iPad 7 Wi-Fi: TG0B Kernel Panic

Wed, 15 Apr 2026 09:16:23 -0700

Got the same issue

I replaced the battery but still getting the TG0B error. The battery level is fluctuating as well. I checked the capacitor C8923 and I got diode resistanc f .883 not sure if this is too high. FL8900 is good as well. What Iam not sure is the Q8900 which for BATT_SWI_FL.

The C8922 which is for BATT_NTC is ok as well it go straight to PMU chip. I tried to jump a wire from the battery terminal directly to batt_ntc n C8922 in case the connection going to the battery is loose but still getting TG0B ... This issue is a pain.

iPad 7 Wi-Fi: Missing TG0B causes kernel panic, plus fluctuating battery level

Wed, 15 Apr 2026 09:11:02 -0700

The problem began 2-3 weeks ago while the device was charging.

Reboots are not spaced evenly at 180s apart, which probably indicates the sensor is responsive at times and not at others? At the beginning of the issue, I could sometimes use it for 5-10 minutes without rebooting, and sometimes less. Charge level fluctuates around 10-20% on each reboot and just randomly when unlocked. The reboots got more frequent and regular over time. Last night it seemed the iPad was charging very slow.

I took it for repair today,

They replaced the battery and the issue persists.

I've read TG0B is an NTC thermistor in the battery.... what could be the next steps? Any possible issues in the measurement circuitry?

iPad 7 Wi-Fi: CPU Replacement - SN reset to original, but failing activation

Wed, 18 Feb 2026 06:33:02 -0700

Hey all! Hoping someone can drop some insight for me.

Had an issue with an iPad 7th gen being braindead. When I removed its CPU, seems I didn't quite get it hot enough and caused an internal short. So I pulled another CPU from an iP7, reballed it, tossed it on, restored the ipad, Changed the SN through Purple back to the Original SN (no reason to have a different SN), restored again through DFU and am where I am now.

Boots fine, is locked to the owners iCloud, but when connecting to wifi I am getting Unable to activate
This ipad connot be activated without an internect connection...

Do I need to generate or change the BT and WIFI mac addresses as well? If so, it seems I do not have the originals to just program on through purple again. Is there something somewhere that can generate them based on the systems SN?

Hope someone knows this and can help!
Thanks - and Pics for fun.

Damaged :(

iPad 7 Wi-Fi: PPVCC_MAIN Interesting Diode Value

Sun, 10 Aug 2025 09:32:53 -0700

Hello one of my customers brought me an ipad 7 and it is not turning on. When I checked it under the thermal camera saw that big power is getting hot on power supply connected to the battery legs and then sarted measuring PPVCC_Main diode value first and found out that it is around 0.170 and I know that it must be around 0.360 .

Because of this first changed the big power as I thought it is getting hot when I plugged it to the power supply without trigger. Nothing changed then I tried changing U2 and nothing changed with it also. And still same diode value on PPVCC_MAIN line.

What can cause this problem and how can I sort this out?

Will be much appreciated if you can show me a way to sort this out.

Thank you

Emre

iPad 7 Wi-Fi: iPad 7th Gen A2197 - 0.47A Draw, Won’t Turn On - Need Advice

Wed, 15 Jan 2025 16:27:23 -0700

Hi everyone!

I’m working on an iPad 7th Gen that won’t turn on. When I connect it to a charger, it draws 0.47 amps. However, if I disconnect the battery, it draws 0 amps.

I’ve watched a few videos in YouTube (mostly from NorthridgeFix) about this 0.47–0.5 amp draw issue, where the problem seems to be a short on the board. In those cases, the iPad still draws that current even with the battery disconnected. However, in my situation, the current drops to 0 when the battery is disconnected.

I’ve also checked the board using a thermal camera, but nothing seems to heat up. I tried measuring some random caps to look for shorts, but I haven’t found anything obvious.

I’m feeling a bit stuck—does anyone have suggestions on what else I could check or test?

Thanks in advance for your help!

iPad 7 Wi-Fi: No signs of life - charges at 2amps for a second then drops

Thu, 09 Jan 2025 15:58:46 -0700

No signs of life - charges at over 2amps (according to my usb amp meter) for a second then drops to zero then back up over 2amps and repeats.

Already changed the charge port but it didn't change a thing. Would this be a CPU issue?

My daughter's iPad charger port is broken and only charges when you put the plug on an angle, but is really finicky.

I know it needs fixing but Santa is bringing her a new one for Xmas so I'm wondering if there are any tricks to get it to stay charging for the next 9 days without having to get it fixed?

Doing a repair on the power connector, I pulled a handful of pads

I can see from the schematic that the pulled pins are:

1 - ground

23 - e75_dpair2_conn_p

25 - e75_dpair2_conn_n

27 - ground

28 - attached to 26 (ppout_e75_acc_id1_conn)

would I need to do any jumper wires and to where?

I was playing a mobile game recently when my iPad screen suddenly went dark blue, I left it for awhile but nothing changed. I tried force restarting it and the blue screen turned off fully but now it wont turn back on at all. I have tried charging it over night with a working charger. It wont even connect to a computer. Is there anything else I should try? (There is a possibility it tried to update because I had not updated it to iPad OS 16 yet.)

iPad 7 Wi-Fi: iPad 7 Not showing battery percentage or charging when booted

Thu, 03 Oct 2024 14:23:34 -0700

Basically i decided to revive my 7th gen ipad from the dead, everything worked fine till it went in a boot loop

I tried using itunes on my pc which didnt work, then i used 3utools to flash it but couldnt go past 19 percent, then randomly it revived and i was so glad

But when i go to the control centre it doesnt say the percentage, so i go to the settings and the battery percentage was enabled

Bare in mind the ipads in charge but doesnt say it is

A while after using it it shut down saying the charge finished, i know the charger i used worked so i recharged the ipad and it turned on but after a while it turned off again

My problem is not the boot loop but rather the fact that when its out of power it charges but when its on it cant charge

I bought the ipad in 2020 its been around exactly 4 years

iPad 7 Wi-Fi: ¿Why my ipad7 is not turning on?

Mon, 15 Jul 2024 09:16:16 -0700

I come here searching for information and help to repair my wife's IPAD 7 WIFI-2019, model A2197. Iam not expert in phone repair, but i want to learn, so i am reading and searching information.

I sent the ipad to a techincal service, but they did not repair it, so i am trying to fix it. The problem is the IPAD is not booting and no turn on.

This is what i found until this moment:

1) with battery connected, the current draw from the power supply is about 450mA from the charging port.

2) no short circuit in lines VCC_MAIN, VCC_BATT.

3) with the power supply, or with the battery, the 3.7V of VCC_MAIN and 1V8_ALWAYS are generated without problem.

4) the current draw from the power supply, without battery, is about 26mA from the charging port.

5) i haven't the diode mesurements of the main lines if power, so i dont known if i have a fuge in VCC_main or other line of principal power.

6) i dont know what other test or action i have to do to diagnostic the fault.

I'll appreciate so much your help.

God bless you, and thanks for this forum.

iPad 7 Wi-Fi: Boots to recovery can't restore

Sat, 27 Apr 2024 11:25:01 -0700

Hello all, I have a iPad 7th generation that only boots to recovery. When attempting a factory reset using iTunes (on a windows machine) or using Finder it errors out.

Looking up the error code gives the common "lost connection" description. I've tried different cables, computers and operating systems with no change in the outcome.

I've even put the iPad into DFU mode but again no change. The iPad attempts to accept the reset only to boot to recovery while the computer's application (iTunes or Finder) freezes up and eventually errors out.

My question, has anyone remedied this sort of problem or is it more like the memory has failed? I was thinking of changing the charge port (even though it seems to charge fine, and is detected when plugged in) but I was wondering if a "data line" has been broken, if that makes any sense.

TIA

So I was just offloading apps since my memory was full and my iPad was lagging a bit so I decided to restart it.

Can someone tell me why this happened? Is it fixable? Is it expensive? Someone please help me. I've already tried charging it for 1 day d still doesn't work.
