DJI Phantom GL300A USB Repair fix no camera view

[@eddyeisenberg5740]

After three years this still holds up quite well. bought a P3A from marketplace for $250. Ended up figuring out the connection problems must be related to this board. This is the only real guide I could find and it was so dead accurate. I cannot express my gratitude enough. I would have hated to spend another $150 on a controller! YOU SIR, ARE A GOLDEN GOD!

[@tjones99]

Awesome. This is what makes it worth doing. Thanks.

[@eddyeisenberg5740]

@@tjones99 after some time has passed, I have now done this method twice. The first board was damaged recently after the controller was dropped and hung by the cord (broken usb port) instead of replacing the port, I bought a "untested" board from Ebay. Did the same thing as before and got the same result. There is something to add that is not mentioned in your video or comments that I am sure can help someone other than me. It occured both times, the first time making me wonder if confirmation the board was working was false hope. When you flash the firmware given by your zip files, it can only communicate with Apple devices, android devices will still remain in the same disconnected state, even with usb debugging and every cord and device I own. I only have android devices. After a week of struggling (the first time) I finally found the solution. The controller needs to be updated to 1.3.2 before it will work with android. From there is needs to be updated even more to be used, this can be done ota through the controller. My dads iphone 7 saved the day twice now. Happy flying!

[@tjones99]

[@toobulous]

I wanted to say thanks, this video helped me recover an otherwise "dead" GL300A board today. Definitely keep making videos like these :). It was a little bit finicky, but I eventually got it working on a windows 10 laptop, and running the command prompt as admin and with "use legacy console" option checked. I figured as I had gotten far enough to see BOOTME, and the first flash attempt there was something out of "sync" with their TX and RX messaging. In case it helps someone else, when I didn't go that route I kept getting stuck on the second flash attempt with and endless loop of these error messages (which I couldn't find much out there searching these): "Image data sent... Waiting for DONE... Target: UART Receive Error Target: Starting UART Boot... Target: BOOTUBL Waiting for SFT on the DM36x... Target: Starting UART Boot... Target: BOOTUBL BOOTUBL commmand received.

[@tjones99]

Thanks for the feedback. Sometimes it is hard to get the FTDI drivers to install in Windows 10 because some of them use unsigned drivers. There is a special boot mode in Windows 10 that you can get into for one restart that allows you to install unsigned drivers. Great instruction on that at www.maketecheasier.com/install-unsigned-drivers-windows10/ And I can't take full credit... all the details posted by others in the forum made this video possible.

[@ourgangmn]

I was really excited when I watched your video, because a week ago my P3Pro exhibited this exact problem for the first time. Mine does have HDMI, and the bottom of the RC clearly says GL300A. Unfortunately, the controller board does not have the markings as the one in the video to specify what the contacts are. I wonder if it actually still has a 300A board or if during the HDMI upgrade (previous owner) the board was changed to a 300B 0r 300C controller board?

[@tjones99]

Not aware of a solution. Sorry.

[@ourgangmn]

@@tjones99 That's what I am finding out, but thanks for confirming that. I know a new board can be purchased for a boatload of money on Amazon, but how would I know for sure that this is the problem? The symptoms are the same. The drone sat for 9 mos and then I flew it three times in a week with no problem. 2 days after the last flight I started up the drone and the RC but the video would not connect. I can raise and lower the gymbal, but I'm really afraid to fly without the video feed.

[@anthonyc2630]

Hi Terry, Thank you for putting this together. I'm still having some issues with the controller after following this tutorial. I followed the instructions and everything seemed to match up perfectly; same error codes, same dialog during the flash process, and same dialog once it was flashed. I reassembled everything and now I'm still not able to connect to the controller (no auto boot into DJI go app, not able to go into camera view, etc.). All it does is start charging my phone or iPad. I reconnected the board to putty and it's still showing a successful boot. Have any other thoughts on how to proceed?

[@stevek731]

Terry, a question about how you soldered the leads on the board. I noticed you just touched the tip of the iron on top of the stripped lead wire and pad but didn't have an obvious source of solder. Do you use a paste on the pad or the stripped end of the lead? Or solder the end of the lead and then melt that again when pressing the lead against the pad? Also, I've got a GL300B controller that just this weekend progressively stopped showing the video stream and then stopped being recognized by an Android tablet (using two different USB cables.) Also tested unsuccessfully with an iPhone 7 and an iPhone 6. I can get into the Go app but it says "disconnected" and no amount of fiddling seems to restore the connection. It worked fine the weekend prior to this. I'm hoping the control board for the GL300B will behave the same with this process as those with an GL300A. Thanks. Edit: Just opened up the GL300B controller and the USB control board looks nothing like the one in the video. The bottom of the board (the side opposite the USB connectors,) is completely blank with no SMC's and no pads other than the ones for the USB connectors themselves and two copper colored dots marked 1765_P1 and 1765_P4. There are some SMCs on the side with the USB connectors and what might be pads but none are labeled. There's a label saying: P01213.02 and a sticker saying: 04EJA 57104. Guess that takes care of that.

[@tjones99]

Sorry, for some reason I missed that you had posted a message. I think in the video I "tinned" the pads on the board which if you don't spend a lot of time soldering means you make sure they are coated with a fresh blob of clean new solder, and off camera I did the same for the ends of the wires so both wire ends and solder pads on the PCB (printed circuit board) had fresh solder so then all you have to do is put the two together and apply heat and they melt together. Soldering 101... So your board looks different... do not give up... Have a look at the pictures at phantompilots.com/threads/fixing-flash-programming-in-dm365-chip-within-gl300-remote-controller.144123/ and see if that looks like your board... if so then my video is just a reference and those instructions should apply.

Never heard of an ftr32 board... ftdi and ftdi 232 board will work... virtually anyything that is seen as a COM port on the PC and translates the communication at a 3.3V logic level will work...

[@tjones99]

My understanding is that the flash cells may be deteriorating and losing their ability to retain which sounds bad BUT as I understand the issue the act of powering on refreshes the cells so the key is to not leave your drone idle for months. Just turn it on every month or do.

I assume you are talking about the little red wires that have connectors on the end to plug onto the FTDI board (USB FTDI board). Those are just simple dupont connectors on wires.

If you get a strong charge and it never goes away, is it pretty safe to assume it’s not dead?

You mean if you get a strong battery charge? I actually believe it should be turned on infrequently as well because I am pretty sure the flash cells get their charge when read _OR_ written and that only happens when on as far as I know. But I am leaning towards this happening more frequently when battery is flat.

Thanks for an awesome video. I'm getting an error with PuTTY saying "error reading device" every time I plug the 5v pin into my FTDI programmer (using an arduino uno - maybe that's the problem?). Any advice?

[@tjones99]

What it sounds like to me is you are confusing a "USB-ASP" type programmer and an FTDI adapter. You can use an UNO as a programmer, and I suspect there is a way to program an UNO as an FTDI adapter (overkill)... but you really want to be using a simple USB to TTL adapter not a "programmer". I have a USBASP programmer that I can program devices by connecting to their ICSP port, but that is a more low level type communication using data and clock lines to transfer data where the FTDI adapter (USB to TTL adapter) is just a form of RS232 type serial communication over logic levels rather than real RS232 levels for long distances.

[@devindorius5449]

@@tjones99 Thanks for the reply. I thought it was just a simple USB-TTL converter. I followed the instructions in this video: kzbin.info/www/bejne/p6K2faqBZqmDbrM I am using a nano clone though so it may have its own weird nuances making things tricky. I'm able to write arduino sketches to the nano so I think the drivers are all in order but can't get the controller's usb board to talk. I'll probably just spend a few dollars and a few days getting one like the one you used. Thanks!

[@devindorius5449]

I wonder if it could have something to do with not being able to select the logic level with the arduino? Since you can select 3.3 or 5v with the adapter you used. Oh well, ordered one. I hope it works!

[@tjones99]

@@devindorius5449 OK, thanks for the link to the Arduino to FTDI approach... that falls under the heading of "learn something every day". I just took a NANO and jumpered RST to GND and talked to it with PuTTY and it worked fine... (are you using an UNO or a NANO? First comment says UNO second says NANO?) But... Your next comment IS spot on (but not the only issue I believe). You can buy a NANO in 3.3V or 5V models... So to get correct logic levels you should be using a 3.3V NANO. So a NANO does have 3 power pins... 3.3V, 5V and Vin (and I suspect that's the same on both the 3.3V and the 5V models from what I read but I only have 5V NANO on hand) and specs that I read say that max 50ma is available from them. This may be too low to power the DJI board... or it may be that the power on surge when the 5V is connected to the NANO causes a momentary power drop that resets the CH340 chip that is talking to PuTTY... or it may be that your DJI board has other issues and is pulling 5V too low due to excess current drain. If you are using a 5V NANO then you are pushing too much voltage into the DJI board and that's not a good thing and that can cause the chips to get into odd modes that draw too much current. But if you are using a 3.3V NANO then you might try powering the DJI board 5V from another source and see if that works better.

[@devindorius5449]

m j putty not seeing your ftdi boards is the first issue. The ftdi should be 3.3v. First get that working without the gimbal board even connected. Connect ftdi Tx to ftdi Rx and plug the ftdi into your computer not connected to gimbal board. Should show up as COM Portland with Rx to Tx what you type in putty should appear in putty window. Then find a way to provide 5v power to the gimbal board. What might work is your second ftdi board set to 5v and only hook up 5v and ground from it. First ftdi at 3.3v hook up Rx Tx and ground for communication only. Alternatively get a 5v dc power adapter.

@@tjones99 Everything ends at the 1st stage of loading when you need to press any key to reset the error. And the download actually starts but ends with an error. I use windows 11. I think maybe I should try to install windows7 specifically. And here is the message itself: Interfacing to the dm36x via UART failed. Please reset or power-cycle the board and try again.

@@ДмитрийФедотов-р3п I am using Windows 10 and I do not expect much difference with 11 so I do not think that is the issue. If the download ends with an error I am worried that perhaps your flash chip has failed and not just lost its contents.

Thank you for the Vid and the files.. After flashing the board my phone now detects communication with the Remote Control. (before it was just detected as charging device). However I still dint get access to camera on the DJI GO app.. On my windows 7 computer when i plug it in, I only see "DJI USB Virtual COM 4" in Ports.. the DJI Assistant Does not detect the Remote Control.

[@tjones99]

So while recently working with some LightBridge units I found there are multiple versions of DJI Assistant... at least 3 versions... and I found that one version detected my LightBridge 1 unit but not my LightBridge 2 unit and a third detected only my drones... I suspect you may be using the incorrect version. It seems you can download and install all versions on the same machine... www.dji.com/ca/downloads/softwares/assistant-dji-lightbridge www.dji.com/ca/downloads/softwares/assistant-dji-2 www.dji.com/ca/downloads/softwares/dji-assistant-2-consumer-drones-series So try the different versions of Assistant and see if any of them connect...

[@tjones99]

@@luisvaldez6204Sorry... I was just working on some LightBridge units and the above reply was applicable to them not Phantom 3 Professional... I do not believe that I ever connected the Phantom 3 Professional (P3P) to my PC and had anything more than what you are seeing on the PC in device manager... at least not connecting to any DJI software like Assistant... Once I had done the flash procedure using the TI flash utility and Putty etc, I then connected the controller to my phone and used the DJI GO app on the phone to connect to the controller and the drone and get live video. I just did it again to test and with my iPhone running the DJI GO app without the controller connected I see the connect to your device screen, and as soon as I plugged in the controller via USB lightning cable the app immediately knew it was connected to a Phantom 3 Professional and said Aircraft Connected. When I click Camera I see the drone camera view. But... my recollection when first doing this was I ran into a number of issues when I was using different cables to my phone (tablet) and different phones (tablets). Specifically your cable must be a charge AND sync cable... many are charge only. And regarding phones... I had some android devices that I was never able to get DJI GO to work with. So make sure you are using a device that is known to work with the DJI GO app. I have personally successfully used iPhone 7, iPhone 12 mini and iPhone 12. I recall using a couple of different Android phones and tablets successfully but I cannot test today as I no longer have the devices or they are no longer running the stock Android on them... I do recall you had to enable USB Debugging in the Android OS before they would work.

[@tjones99]

@@luisvaldez6204Oh, and another viewer posted the following comment recently "When you flash the firmware given by your zip files, it can only communicate with Apple devices, android devices will still remain in the same disconnected state, even with usb debugging and every cord and device I own. I only have android devices. After a week of struggling (the first time) I finally found the solution. The controller needs to be updated to 1.3.2 before it will work with android. From there is needs to be updated even more to be used, this can be done ota through the controller. My dads iphone 7 saved the day twice now. Happy flying! "

Would it be easier to do it on windows 7 or 10. If it is easier to use windows 7 can a use a vm(virtual machine)?

[@tjones99]

I had no issues on Windows 10 so not sure adding the extra layer of complexity makes sense.

Will this work with GL300C controller too?

[@tjones99]

Sorry, I can't say. No experience with the 300C. For sure you would need different firmware than what I link to in the description... pretty sure the firmware I point at would brick the 300C

Hi, thanks for the video, seeing it done is alway useful. However I am deaf and reliant on the subtitles which I have found are often rather difficult to follow on ANY youtube. Can you please clarify the following points, 1) around 13 minutes you disconnect the +5V, why and is it mean to remain disconnected for the reprogramming etc.? 2) Around 15min you 'say' "this time I'm gonna hold the BTS 15:11 ALV wire onto the 3.3 volt as I plug it 15:15 in we will get different messages so now 15:19 the board has booted into a boot me mode 15:24 and it just sits there saying boot me " Are you talking about connecting BTSELV pad to the 3.3V pin on the USB-TTL device? If so is it a momentary contact or do you leave it connected?. In a phantom pilots article phantompilots.com/threads/fixing-flash-programming-in-dm365-chip-within-gl300-remote-controller.144123/ a wire is soldered between the BTSELV pad and an adjacent 3.3V pad. I have followed you video and see what you show etc. i.e. repeated bootme's, then the program running and halting etc. and requiring the reissue of the command after which it seems to work and I get the "operation completed successfully" message but when I reboot the board I am back to the repeated bootme messages. Any ideas?

I will address you’re queries when I get home from the lake and am on a fast internet and a full sized screen.

[@metalmikey2]

@@tjones99 excellent, thanks.

[@tjones99]

OK, let me have at it and thanks for making me more aware of this issue so I can try to be more descriptive in future. 1) around 13 minutes you disconnect the +5V, why and is it mean to remain disconnected for the reprogramming etc.? I disconnect the +5V but leave the FTDI adapter plugged in to keep Putty happy just so I don't error out of Putty and keep having to reopen Putty... lazy... 2) Around 15min you 'say' "this time I'm gonna hold the BTS Just before that I show a boot without the BTSELV connected wire shorted to 3.3v and it fails to boot, then I say I am holding the wire to 3.3V and power on and I get the BOOTME message. 15:11 ALV wire onto the 3.3 volt as I plug it 15:15 in we will get different messages so now 15:19 the board has booted into a boot me mode The above 3 are related to 2... to put the board into the special boot mode to receive the upload you have to connect BTSELV to 3.3V on power up. 15:24 and it just sits there saying boot me " Are you talking about connecting BTSELV pad to the 3.3V pin on the USB-TTL device? If so is it a momentary contact or do you leave it connected?. In a phantom pilots article phantompilots.com/threads/fixing-flash-programming-in-dm365-chip-within-gl300-remote-controller.144123/ a wire is soldered between the BTSELV pad and an adjacent 3.3V pad. So good question here... It is a momentary connection on boot I found. The BTSELV wire connects to the 3.3V pad on the board that is close to BTSELV. This is the soldering part at 8:04 where I say I am soldering the wire to the BTSELV pad so I can hold it to the 3.3V pad on power up. I have followed you video and see what you show etc. i.e. repeated bootme's, then the program running and halting etc. and requiring the reissue of the command after which it seems to work and I get the "operation completed successfully" message but when I reboot the board I am back to the repeated bootme messages. Any ideas? If you do not disconnect the BTSELV wire from 3.3V it will continue to boot in special boot mode and repeat BOOTME Hope this helps!

I did everything according to the instructions, but there were errors in nand, it was stitched without problems as in the video from the second time, I put nothing changed as I did not see the remote control, the phone does not see it. the procedure was performed on windows 8.1 (32) USB-TTL CP2102

[@tjones99]

If there were error messages when the sfh_DM36x -nandflash program ran then my suspicion is the NAND chip itself has failed or has a solder problem on your board. That is not an easy fix usually requiring special soldering equipment and skills.

hello my friend from indonesia i tried to follow the method you taught in the video, but when i try to connect the ttl to computer, my dji device doesn't read. please help my friend, thank you.

Well the first thing to try is to confirm that the TTL adapter is working. If you connect Tx to Rx directly on the TTL adapter and open the putty connection you thould be able to type and the characters will appear in the putty window. Confirm that works first.

I looked at that German video and basically the exact same as my video but using different files that the author makes available on Google Drive to download. Same FTDI adapter, same PUTTY program, same procedure just solder to the pads he shows in his video and use the files he has on his download. Just ignore the words and follow my procedure with his file and his connection points.
