Hello! Well, that is a secret 😁. Joking! I'm using a custom made power supply based on XL4005 IC. I know that is a short because power supply is jumping from the blue led to the red one (you can't see it because of the camera shutter speed) then to de green led and so on! You can see that even on a usb power meter that is fast enough.

Roman sunt! Merci pentru comentariu! Spor!!!

Thank you

12 mini has a very problematic motherboard! 100% you need to separate the boards!

@PhoneRepairRO to be honest I find it very hard to sort out the pads otherwise reballing wouldn't be a problem... Is iphone 12, 13 or further models have problems with pads also as i have seen lots of videos that all them just did reballing to fix a no imei issue...

Hello, UNI-T UT171B

@@PhoneRepairRO thanks, It is a little pricey. I use a Fluke 17b+ multimeter. Have you used a UT61d+? It does the same thing, but I am not sure how it operates.

@@Sherifone78 Never used the UT61D+, i that also has usb! And about the fluke, i played once with one, but i don't like because seems to have a bit of lag on diode mode!

@@PhoneRepairRO Ok, thnks for replay, subscribed to channel, all best wishes.

In this case i don't think is some cap shorted. You can try and inject 1.2-1.4v / 1-2Amps and see if something is getting hot. 80% baseband cpu is gone. Try to take BB out and check. Have a nice day!

@@PhoneRepairRO thank you ! I did injected and a capacitor turned hot on a heat camera but also looks like there are more capacitors defect do you think is Posible ? Because there is another one that also get hot when I Inject

@@j537nl The phone had water damage? Take out caps that are glowing on thermal camera and see from there on!

Thank u new subscríber 💪🏻

@@PhoneRepairRONot that I know, I didn’t Heard from the previous owner thet it water damage had. If so would it explain the short ?

Thank you!

I'm using Wuxinji, but there are many programs that do the same thing!

@@PhoneRepairRO thank you for your response. I have a few questions if you don’t mind me asking. I have a 12 Pro Max that was boot looping due to storage full, I tried to restore or update, fix flash on 3u tools, I unplugged everything on motherboard except battery, lighting port, and power button, nothing gets it working. Now computer sometimes reads the phone in dfu mode and most of the time there is a usb error saying it doesn’t recognize device, the phone takes a charge at 0.438 amps but nothing showing up on screen, have you dealt with this before? what could it be? Also at 3:41 I see you are checking from the battery point J10000 to another ground point on the upper motherboard and say there is no short anymore, how is the short gone when you are reading from a ground point from battery connector to another ground point on the motherboard? Also, what points on the motherboard do you apply power to see if something is short circuiting without shorting anything else? Is it power and ground in a certain circuit? The circuit lights up where powers and ground is for a particular component in Wuxinji program, sorry for the long comment and questions but I’m just trying to understand, thank you.

@@ThatDIYguy862 Noo, at min 3:41 i just read the resistance of my multimeter leads, then if you look till min 4:00 you will see that i measured on the + terminal ( i know, the text on the screen is a bit off - i will start to make videos with voice in future ). I normaly apply voltage / current only on vdd main, but never on battery conector ( on 12 / pm vdd_main is conected to battery connector with a .0025ohms that might blow up ). Wuxinji and other programs lights up all components that are conected to a certain line ( ex vdd_main, pp1v2 and so on ). To find where is vdd_main you go close to PMIC and there will be lots of capacitors conected to vdd_main - never go up with amps! Regarding your problem, the phone now is in dfu. Have you put the motherboard in another known good case? This will be the first step! Have a nice day!

@@PhoneRepairRO What should the resistance value be when connecting one lead to number and the other to number 4 of connector J10000 (battery connector)? Power pin to ground pin is what it that is. I am getting a resistance reading but I am not getting a continuity reading on it. And do you have any idea what on the J11200 connector circuit would case a short or something so that computer cannot read the phone?

@@PhoneRepairRO I also found another weird thing, after I freeze the phone in freezer for 5-10 minutes, the computer start to read it again, when it warms up, it doesnt work anymore again, you think something is shorting it?

Hello!!! Well, i went to a light store / LED light store and i bought an LED spot light with one big LED ( you can buy 2 LED spot light ) and i mounted that spot on a flexible arm then i fixed that arm on the microscope frame!. And here's your anti glare light under 10-15 euro! Have a nice day!

@@Sherifone78 preheater video is in the making, but i don't have time :))! As you can see the last video i posted is about 2 months ago, and man, i have so many videos to post....

@@PhoneRepairRO subscribed, waiting for other videos too, you have gr8 videos. 1 advice to raise your viewers. Its hard maybe bur Air and Temp is very important if they are described on videos. Thanks

@@Sherifone78 hello! Multimeter is one from UNI-T UT171B with usb connection!

@@PhoneRepairRO thank you!

Hello! Is isolated wire from iphone 6 or 7 earpiece speaker.

Hello! I always check the continuity and it has the continuity, the problem is when it start switching, the wire inside the coil drops continuity to 0 sometime. So somewere is a crack or some break point. Is like on the iphone 12/12 pro earspeaker, the wire is ok, but when you check under microscope you see that is broken :D .

Thank you!

Bucharest, Romania!

Hello! At that time i didn't had the reball stencil for iphone 14 series, so what shall i do - refuse the client? Never!

Hello, No, the phone had no water damage! What you see there is flux, and that green stuff is UV mask!

Thank you!

Hello, I can help you with the repair, but i don't know if it's ok for you to send your phone in Bucharest / Romania.

@@PhoneRepairRO It's a bit too far Im afraid, I thought you were in china or the state. Thanks for uploading these helpful videos!

@@1point689 Yes it is! If you want, i can recommend you someone from USA. Very good tech!

@@PhoneRepairRO i would love to know the info!

@@1point689 Here www.ststele.com/mail-in/ this is the site, and this is his youtube chanel www.youtube.com/@ststele . Again, a very good tech, i learned alot from him!

Glad it helped

Never seen one of these Asus EKWB with an air cooling. It might be possible!

Hello, charging IC on Iphone XR is different than Iphone X. What is the problem, is not charging or the charger is not detected? Shows 1% battery? When the phone is off and you plug the charger, the phone is powering up?

when i plug a charger .phone on but not show charging icon after few mint fone restart again and again

@rsrepairinglab4311 battery data! Battery does not speak with the phone somehow! Check battery connector on motherboard, test with another battery!

try with new battery but same

fone can't connect to computer

Hello, What model is the iPhone? That error is a software one!

@@PhoneRepairRO it's iPhone 11

@@PhoneRepairROThank you how can it be fixed,?

@@NancyChoto-y3o Use iTunes, not 3uTools, update your operating system first.

@@PhoneRepairRO Thank you!

Hello! I took out a shorted capacitor! There are many others on that line in paralel! It works whitout no problem!

Hello! I don't have a repair shop. I do this as a hobby!

@@PhoneRepairRO 😔 Looks like these iphone12 are all garbage. Mine doesn't power up and overheating. Tried everything. Don't know if I bring it to Apple if they will warranty it

@@rickmucci4785 You might have a short on some nand line or somewhere else. If it is under warranty go to Apple ( i hope you have some backup on icloud or on your pc ) - they will give you another phone. If not, go to a repair shop that do microsoldering ( all will say that they do microsoldering - look on reviews ). Where are you from? Maybe i can recommend you some repair shops! Have a nice day.

@@PhoneRepairRO Thank you so much. No warranty, just heard that since they had problems with these things that they might do the work for free as a recall or some but I think it won't happen in this life time 🤷 Montreal,Canada. Can it be a capacitor?

@@rickmucci4785 If they don't have a recall program, not a chance! It's a 50/50 the thing with the capacitor, but you say that is overheating - that means the phone try to power up till a point - there are some power lines that come on after you press the power button / or you promt to boot with the charger - so it might be a short somewhere. You can send your phone here www.ststele.com/contact-us/ , the shop is in Sarasota / Florida / US (much closer to you than Europe / Romania). Jason is a guru in this industry, is the guy that made Apple to recall all iphone 6 / 6+ that had "touch disease".

In time some ceramic capacitors get shorted! They are badcaps :D

@@PhoneRepairRO thanks !!

Hello, If you are talking about those 2 black rectangular parts, those are mosfets used by cpu to speak with battery. If you have an open line when you measure the 2 data lines on battery conector in diode mode and on one of them you have open line, one of the mosfet is disconected!

Glad that the video helped! Is a common fault on this model. Have a nice day!

Hello, I injected on PP_VDD_MAIN. Have a nice day!

Hello! Yes!

Thank you!

This repair stopped me to post any video for more than 3 months, lol!
