LG G4 Boot Loop Chip-off Data Recovery - 100% Success!

[@beckyshock3099]

YEA !!! SOMEONE ACTUALLY SPEAKING!!! THANK YOU.... I WENT THROUGH ABOUT A HALF DOZEN VIDEOS TO FIND THIS ONE

[@ALPHAJACK78]

Good video but I just wanted to let everybody know at two minutes 57 seconds on the video you’re pointing to the memory chip, what I did was apply heat from a 1500 watt hair dryer to the center chip, for 10 minutes, 1/4 inch away, reassembled the phone and was able to boot up and recover all my important info, pics, videos, etc. Now, I said that to tell everyone that I’m sure it’s not a permanent fix, but it was enough for me in my circumstance to get what I wanted, then do a factory reset and destroy the phone and never buy LG products again. Thank you for this video and your services to help others, it was very educational.

[@SamFBM]

gonna do this to mine soon , get all my old stuff back from bootloop probs

[@douglasjensen8986]

I hope this convinces LG G4 users to back up their phones to the cloud or a microSD card.

[@MPRF12345]

I had my photos and all in a micro sd card. Then it got full. Only took me like a week to get a new one. Problem was: we were on vacation during said week, meaning loads of important photos taken daily, that I didn't have the time to backup because it stoped working still on said vacation and I was going to do it once we got back home :(

[@douglasjensen8986]

@@MPRF12345 I know this is easy to say, but: when traveling, especially anywhere other than in a major city in a first world country, assume that you will have problems and prepare for them. For example, I always have a spare empty large capacity uSD card for my phone, and at least one spare battery for the phone, plus at least one spare of every kind of cable that I normally (and perhaps not normally) use. None of these take up much space. I even always have a spare phone. And I do all this even if I am going to downtown Manhattan.

yes

[@carloisdoingstupidtechstuff]

@@RoUt204 well, can an eMMC work without DAT1, DAT2, DAT3 as long as it has DAT0, CLK, and CMD? I am going to solder it on an external SD card reader if it would work

[@delmarfenn7068]

Just for anyone that didnt know, the boot loop failure is a thermal failure! You can put you lg g4 in freezer for 1hr and ne able to start it up to download info on computer for 5 min! Rinse repeat till all needed info collected.

[@flashfixers8180]

We've heard of both freezing and/or heating as possible solutions to the boot loop problem.. If it works for you that's great. We've been getting 100% of these recoveries for some time now. Our chip-off data recovery is an option after you've tried everything else and nothing has worked, and the pictures on the phone are really important to you.

[@harveydavis2311]

Will a similar process work for a LG G5?

[@alessiovecchiet]

Is it possible to install the eMMC chip to another g4's motherboard? How much temperature does the motherboard and the emmc support after they become unusable?

[@flashfixers8180]

I haven't tried this before, but it should work. I try to keep the heat under 400C.

[@patrikstaron]

You should also reball the chip properly and position it correctly. It is kind of a hard one. To do resoldering, choose balls with melting point that are fine with the maximum temperature the device can get to, so that something like bootloop on snapdragon would not happen to this chip. Then heat the board in a linear fashion and the chip as well to melt the balls on the board. The multi-layer board can withstand temps up to 400°C for about 10 minutes but do not bend them. This is and extreme situation. Use as little temperature for as short time but enough to melt all the balls and all the pads both on the board and the chip. The chip temperature depends on the technology and internal parts. For soldering, follow the steps of [pre-heat, pre-reflow, reflow, cooling]. There are temperature/time graphs on the internet (reflow soldering graph). Adapt them to your needs.

[@stevemojacar6562]

will this work for lg spirit lte ?

[@madadventures3407]

Has to be running android 6.0 or lower for no encryption

[@AndrewMooreJ]

Thanks for the video. The way I usually do it is running a beveled iron; LEADED solder, over the bottom of the BGA after removal. After I have enough solder on each sphere, evened out as much as I can. I rub it over a piece of paper until they are even, and replace. I like your method - Can please please link the exact model of the SD adaptor/reader for me? That seems like a cool alternative in case something goes awry with my method. Thanks in advance.

[@portercooper3121]

[@deviantlinux]

This is awesome work! Nice!

[@ryanrydel9114]

Anyone ever have some of the solder mask (from the motherboard, the green resin coating) come off with the chip!? At first I was worried that I left some of the chip on the motherboard, but nope, it's just a layer of the green stuff glued to the chip! (I have a decent rework station, I thought, but I was wondering if it wasn't hot enough. My final round was with 740 degrees F, because it just wasn't doing anything for way too long!) In any case, thank you for the great video!

[@noe8615]

Is the flux mandatory ?

[@TheSlothman3041]

Awesome video! What kind of tip are you using on the soldering iron? Is that a blade tip or more of a blunt tip?

[@flashfixers8180]

Thanks Alan! The soldering tip is flat angled angled tip. It's important to put the chip on a flat surface. I use some flux when removing the epoxy underfill. A solder braid also helps, but be careful not to scrape the chip too hard and expose the etches.

[@flashfixers8180]

Its more of a blunt tip. Not too sharp.

[@Tostaki92]

can i use this chip to another motherboard same model?Is this possible ?Just an idea!

[@flashfixers8180]

I've never done this before, so I don't know if it would work. If you try it let us know!

[@itechcarezhao389]

I am curious too, please let me know.

[@faysalbest1]

my g4 is encrypted. would you be able to recover any data from it?

[@flashfixers8180]

No it's not possible to get the data using chip-off if your G4 is encypted.

[@faysalbest1]

FlashFixers anything else cold be done? Money is not an issue. I want to save my data. I encrypted my phone using the Android operating system.

[@JUST_ONE_ID10T]

If you watch videos on youtube there is a way that mostly works to get the phone to reboot again by taking the phone apart and putting something inside the phone that when you put it back together it applies pressure to the chip. then the phone boots without issue. I have done that to a few phones. Sometimes the phones will work for ever and other times it's just a temp fix. the only way to repair the phone is to reball the chip that is getting the pressure applied too. There are youtube videos showing you how to do so.

not necessarily...mem array still might have had damage from heat or electrostatic discharge, while the file allocation table seems valid, the actual file data still can be corrupt. nevertheless, dude's fine , could save the chip in one piece, a chip which was never meant to be removable. and it actually worked !

[@adamidan3792]

can you make recovery from the emmc if i have pincode lock on the device ?

[@flashfixers8180]

Yes. Chip-off works even if the device is locked with a pin code. The security layer is after the userdata and does not block its direct access.

[@adamidan3792]

Nice

[@Mark-hs8ys]

After the 400c preheat, what was the temperature of the hot-air machine?

[@flashfixers8180]

Temperature is a variable based on your hot air equipment and the circumstances of the chip (amount and type of underfill). You'd have to try different settings and see what works best for you.

[@maxmustafaful]

Or you can hear the board about 4 minutes and it's should power up

[@bas182341]

seems easy. is this doable for someone with almost 0 knowledge of soldering and soft/hardware? is the emmc chip damaged fast in this proces?

[@flashfixers8180]

Like anything, your technique and confidence grows with practice. I've done hundreds of chip-offs.. but you still have to be very deliberate and careful with each one because you only have one chance to do it right. I'd suggest that you buy some used phones to practice on first, before attempting on your own. If you'd prefer to have it done professionally with best chance of recovery, or rather not buy the equipment for infrequent use, you're best to hire a data recovery company with a proven track record to do it for you.

[@bas182341]

hmm thanks for the response. had contact with a recovery company and they ask 900euro. well..thats a lot but ok, worth it. but it also takes 4weeks and since im in a hurry i guess im kinda forced to do it myself unfortunately

[@flashfixers8180]

After we receive eligible phones for chip-off we usually turn them around in 24-48 hours. We accept all international shipments, and to save time can upload recoveries to cloud storage where they can be downloaded from any location. Visit our website www.flashfixers.com for more information on submitting your case.

[@bas182341]

hmm looks interesting. my case is special though. i cant get into my phone because of a bootloop and i actually only need the Google authenticator (2fa) app. is this possible? (i do know you can redownload it and use 16digit key, but it doesnt work somehow and im 100% sure its an extern mistake)

[@jayajaya1884]

[@DIYTy]

What type flux are you using?

[@flashfixers8180]

Amtech RMA-223-TF. You want something that is not too thin and runny, otherwise the epoxy won't mix with it well.

[@MrLucasBS]

But how about the bootloop ? after this is it fixed ?

[@flashfixers8180]

Chip-off is for data recovery only. We don't fix the boot loop. Anyway the phone can't function without it memory chip, but you have a way to get your photos and videos back..

[@anirangs]

Does this process works if the phone was in encrypted state before it went for boot loop error?

[@flashfixers8180]

Whatever is on the memory chip is extracted. If the phone has encrypted memory, chip-off won't change that.

[@jdaz5462]

My phone, LG G4, took a really hard fall (in other words, I threw it at the floor) - Now it doesn't power up at all. What can I do? I have a lot of important info - Does this get contacts? Text messages?

[@flashfixers8180]

Yes this chip-off data recovery process works for physically damaged phones as well and recovers the phone's entire internal memory. It works for contacts and text messages as well. Here is a direct link to our web page dedicated to boot loop recovery: flashfixers.com/lg-g4-bootloop-data-recovery/. You can outsource the chip-off process on your phone to FlashFixers by clicking on the link on that web page and completing the online form.

[@muhammadsaeedkhan1930]

is the boot loop can not be fixed/repair

[@makunouchiippo2542]

yes it can, but do you really want paid over 200 for it ? what happens is the cpu overheats and breaks the solder , what you need is reballing the cpu, if is just boot looping remove the thermal paste, the heatspreader and put a new heatsink and some new thermal paste, or cu tape double side to spread the heat around the battery but if is on a infinite boot loop the cpu is done

There is an investment required for the proper equipment and fixtures. As an option, we also offer chip-off as a data recovery service through FlashFixers.

[@davidtorres8426]

I always thought these nands were better encrypted Does a method like this exists for iphone?

[@flashfixers8180]

iPhone NAND memory has been encrypted since iOS 4, so this method won't work. For new Android phones with factory installed 6.0 or higher, encryption is enabled by default same as iPhones. Legacy Android devices 5.X and below (AND those that upgrade to 6.0) can still use the chip-off method for data recovery. Some newer phones (eg. Samsung Galaxy Note 5, S6, LG G5) use UFS memory instead of eMMC. UFS requires a different fixture and programmer, but that's another video.

[@kierstensowell2569]

So if my HTC came with 4.1 but was updated to 6, it would not be encrypted? I know for sure that it had lollipop at one point, but I don't recall if I updated again after that. And thank you so much for your useful videos! Definitely the most well-made one I've seen so far on this topic. I'm starting to feel like there's finally some hope for my data.

[@flashfixers8180]

If the phone came with Android 4.1, it should still not be encrypted even if it was upgraded.

[@kierstensowell2569]

Awesome, thank you! Are eMMC's really as durable as they appear here? I lost 3 years of photos and can't afford professional data recovery, but I have access to the necessary tools (minus the reader and software, I'd have to find those.) Would I be likely to damage the chip if this is my first time doing anything like this?

[@virtuelllife2677]

Here's a solution -it sounds really stupid- My phone became in bootloop situation and then i hit the top of the phone with a wall and kept in its position hit it multiple times and turned on and it worked on my lg g3 hope it works with you. important dont hit the phone really hard I dont think it will stay for long terms
