Hi

New member here, so the problem is

1. Phone is stuck on - Powered by Android screen and automatically gets shut down or sometimes need to remove the battery to turn it off.

2 By Pressing volume down + power button = Phone enters in recovery mode which looks like the photo I am attaching here

In the above picture you can see the Errors I am having in recovery mode. 👇

E:Can't mount /cache/recovery/command

E:Can't mount /cache/recovery/log

E:Can't open /cache/recovery/log

E:Can't mount /cache/recovery/last_log

E:Can't open /cache/recovery/last_log

Some say it's emmc chip failure but I read a forum here ( that's for another phone); in that post, someone posted exactly the same errors and he managed to fix the issues. I will post the link to that forum if I found it.

HOW IT HAPPENED

The phone was on charging and I pulled out the charging cable and turned it on and after powered by Android screen this recovery screen appeared out of nowhere. It was on charging overnight.

------------------------------------------------------------------------------------------------

BY FAR WHAT I HAVE PERFORMED

1. I did wipe the cache partition first. - no use

2 Then I downloaded the firmware (2 firmware) and Qualcomm USB loader 9008 drivers and qpst and qpil, after that, I copied the firmware zip files in phone's sd card and tried the " support from SD card" option in " recovery mode ", didn't work, stopped automatically, it was so quick that I couldn't read the errors.

3 Now I tried to wipe data/ factory reset - nothing happened, the process started and stopped automatically.

4 I tried to flash rom on it, ERROR - download fail sahara fail, sahara server fail. Every single time, I changed the versions of flash tool USB drivers, old versions, latest versions, my laptop is flooded with unnecessary versions, it drive looks pretty messed up right now. Zip files and extracted files everywhere.

5 at this point I tried adb and fastboot, adb devices command shows my device name successfully but after that no command works, sometimes it showed failed or sometimes - waiting for device.

Sometimes it keeps saying - *failed to write data 'protocol fault (no status)' *

EXTRA- I don't know if the bootloader is unlocked or locked or USB debugging is on/off.
