How to revive Nexus 7 2013 LTE version?

Question

Android

In general, these signs:
1. With normal power on, it hangs until the battery is discharged on the Google logo.
2. We switch to the "Power + Volume down" mode, it enters, it reacts to the buttons.
3. We select the recovery mode, 15 seconds and a droid with an exclamation mark.
4. When you try to unlock the bootloader, it freezes, does not respond to buttons, and hangs in the terminal:
(bootloader) Unlocking bootloader...
(bootloader) erasing userdata...
The firmware was native, did not drop, did not drown.
PS It's a pity the tablet ... I like it very much ..........

Answer 1

BEFORE the tablet was corrupted, were any updates installed over the air? And what version of the bootloader is displayed in the bottom left corner when booting into pre-recovery? If there were updates and the current version of the boot is 4.21, then this is exclusively a board replacement. In one of the updates there was a broken bootloader, with the firmware of which quite a lot of devices died like that.
Himself literally a month ago I was picking Nexus 7 2012 Wi-Fi. The same symptoms, but they immediately said that he died after some kind of update by air. If you are interested in details, how is it, then google the XDA-Developers forum, I found this info there. In addition, in the caps for topics about Nexus 7, both on the CDA and on the 4PDA, there are footnotes that installing updates via OTA is highly discouraged .

Answer 2

Well, that usually means the mother is dead.
Try to flash the official firmware from the Google site . You will find all released firmware here
. It is assumed that you have all the necessary firewood, all wires-USB ports are working, unzip the archive to files, including flash-all.bat, something like that. Then go to the bootloader and connect the tablet. Look for more detailed instructions on the 4pda forum, in the profile branch, usually if the factory firmware does not help (and you tried different versions -4.3, 4.4.4, etc., this means going to the SC.

Answer 3

I have the same tablet, very often there are similar problems. One question: Do you have problems with the power button/sound freezing/mute or touch screen lag?
