iPhone 7 Stuck In Recovery Mode

Postby compu829 » 18 Jan 2018 04:10

Hello,

I have an iPhone 7 that is stuck in recovery mode. When I take it out of recovery mode, it boot loops. when I try DFU restore in iTunes, it never kicks to the "RestoreOS" phase. I see an empty progress bar, and it instantly reboots back into recovery mode. I see the same thing using "Easy Flash". I have tried 3 different computers, 3 different USB cables, and 3 different OSes (macOS, Win7, Win10). When I use Pro Flash mode, I never get to the restore screen with the apple logo. I get the following log:

Code: Select all

14:53:32   Flash and jailbreak of apple device, please visit official website of 3uTools
14:53:32   Elapsed Time: 00:00:57


Anyone have any ideas? I have been reading things like "Replace the NAND", but I don't know if that is the problem before I open it up. When it is in recovery mode, the "iDevice" tab reads all of the correct info, except nothing is reported for the device size.

Hello,
And what is the error on Easy Flash?
For your information, there is no 3uTools for mac at present.

Hello, I understand that. I was trying to say that I tested with multiple devices with and without using 3uTools.

Easy Flash hangs at 19% with the word "Restoring" in regular flash mode. IT eventually returns "Error Unable to Restore iDevice (-2).

Easy Flash says "Sending Ramdisk", then "Sending KernelCache", and lastly "Restoring". As soon as it says "Restoring" the phone immediately reboots away from the screen with the progress bar. When I am in DFU mode, Easy Flash says that it cannot switch to Recovery Mode even though it eventually switches. When I used "Pro Flash" I got the log that I posted above.

Let me know if you need any more info.

Hello, I think it is about hardware problem. Did you try to restore to another iOS version?

I did. I tried the latest 11.2.5 beta as well as iOS 11.2.0. I noticed that the baseband changed between 11.1 and 11.2, and I am wondering if maybe the update failed.

What is strange is that the main device page in 3uTools reports all of the information about the phone without fail. so I don't think it is a NAND issue. I wish there was a way to see exactly what is failing!

Normally, error -2 would be caused by hareware problem. But not sure which part of hardware, you are suggested to get a repairman to check your device.

I tied flashing it via iTunes, and I noticed that an error about not being able to read the baseband keeps coming up. This error appears more times than on a phone that will flash. I think the kernel can't talk to the baseband chips, causing it to panic. I am going to try and reflow the chip and the PMIC to see if that fixes it.

It appears that maybe your iPhone 7 data files takes up too much temporary space, which easily makes your program crash. For me, I am using Joyoshare iPhone Data Recovery, an iOS data recovery that enables me to find data from iPhone/iPad/iPod touch, iTunes or iCloud backup with high success rate.
