Elimde 2 adet 5s bulunmakta ancak bunların anakart sorunu bulunmaktadır.Tekniker olarak bunlara herhangi bir işlem yapamıyorum.Türkiye de sadece anakart tamiri yapan yerler var mı ya da ben anakart tamiri yapmaya kalksam video kaynaklar bulunuyor mu ?Bu konuda yardımlarınızı acil bekliyoru.Çünkü bana çok fazla anakart tamiri için cihaz geliyor bende yapamadığım için geri çeviriyorum.Şimdiden teşekkür ederim.

I'm thinking that if I put the original Operating System back on (iOS 7 I believe), then I wouldn't have to deal with activation lock.

Guess what though, iTunes will not let you put the original OS back on. So, I downloaded the firmware, but I can't restore it because I don't have a program to do it.

I have found several 3rd party programs out there that claim they can do it, but I do not trust them, plus they won't work until I pay over 60 dollars in advance.

So, where do I go from here?

I have an iPhone 5S running iOS 7.1.1 which is quite rare these days and has sentimental value to me, so I want to avoid upgrading iOS at all costs.

The phone is stuck on the activation screen and shows "Searching…" in the top left corner permanently. I connected it to 3uTools and noticed the following:

• IMEI 1 & 2: None
• Baseband Version: Empty
• Baseband SN: Empty
• Baseband Status: BBNotReady
• Cellular Address: Shows a valid MAC address (84:B1:xx:xx:xx)
• Coprocessor: None

The phone also randomly displays a blue screen (kernel panic) approximately 1–3 minutes after booting and then reboots.

I exported the real-time logs via 3uTools and found the following repeating errors throughout the entire log:

AppleD2045PMU::_readADCGated(x) ADC read bad state: 1
AppleD2045PMU::_readADCGated(x) failed with status=e00002d6
CLTM: Could not get value for PMU tdev1/tdev2/tdev3/tdev4/tbat/tcal/tjunc
CommCenter: com.apple.AppleBasebandManager.RadioNotReady
CommCenter: CSI state dump requested: modem boot up failure
BBUpdater error 3 — Failed creating a communication transport to baseband

Every single ADC channel (2, 8, 10, 11, 12, 13, 14) is failing with kIOReturnNotReady consistently throughout the entire log without a single successful read.

The phone has had a screen replacement done previously. Long screw damage was considered but ruled out because the phone actually boots, reaches the hello screen, and works for a few minutes before kernel panicking — classic long screw damage usually results in immediate boot loops or no power at all.

My theory is that the D2045PMU chip has a partial internal failure — specifically the ADC block is dead while the core power delivery functions still work (hence the phone boots). This would explain both the kernel panic (iOS can't read sensor values) and BBNotReady (baseband can't get proper power/communication).

My questions:

1. Does this log pattern confirm a D2045PMU hardware failure?
2. Would a reflow be worth attempting before replacing the PMU?
3. After PMU replacement, will iOS 7.1.1 recognize the new chip automatically or is any additional firmware/software work needed?
4. Any chance this could still be a software issue given that the cellular MAC address is visible?

Thanks in advance.

But when removing the screen, it seems like I only have lifted part of the screen?

My home button stayed in place and i also can't see the internals.

Kinda stuck now. Any suggestions?

Does that mean I would need to replace the LCD in order to get rid of it?

First time trying to fix an iPhone so any insight is greatly appreciated!

So after a look around the internet I couldn't find anything the same.

I tried changing the charger to another working one in our house. still the same

I tried doing a reset (holding down the power and home button until the apple logo comes on then releasing)....still nothing.

I tried clearing the phone and fully resetting every, nothing still.

I do keep my phone updated, however this happened long after.

So sounds like the battery right?....

I changed the battery and it charges like a trooper, woohoo!

First thing I notice is that it seems to stay at 100% for too long.

After 2 days it starts to drop to 95% and won't charge again.

So I change the battery again, and it charges again...

Same thing as above.

after fitting the battery the 2nd time around, I charged it for 8 hours as they tell you to when buying a new phone?

but still no joy.

I'm wondering if theirs something you're supposed to do when fitting a new battery?

Or... do you think the board is gone?

Or..just another faulty battery?

Seems funny that they all do the same.

Before all this, my original battery was just fine.

Hi, Nothing went wrong with the change over at all. I'm not a repair guy but I'm quite handy with this sort of thing.

I just find it funny how it charges for 2 days then stops.

Unplugging the battery for a few minutes doesn't get it charging again either. the only way to get it to charge is to fit a new battery. almost like it's popping a fuse inside the battery? might be over charging?

If it's not the battery, then the original battery must not have been at fault in the first place.

But still can't understand why it charges when changing the battery.

The power button seems stuck down. No click or movement felt when pressing it.

Connecting the lightning power cord gives an immediate Apple logo for ~20 seconds, sometimes followed by a brief full-screen red flash, then the screen goes dark for a few seconds before the Apple logo reappears. This cycle continues indefinitely.

Thoughts? Many thanks.

Update: The red-screen doesn't always happen.
