3 weeks ago i rooted my phone and installed a custom ROM but it got stuckk in wiping the cache but somehow i fixed it and installed a stock ROM (4.4.2) after doing all this my phone worked fine for 2 weeks and suddenly early morning it went off and dint boot-up and now its stuck in the bootloader menu, and no recovery, so i tried to get it back to Stock so as i started i got my Phone into re-lock state and made it S-ON but now it doesnt accept the RUU and even The OEM RUU BOOT fails! and if i try to UNLOCK AND S-OFF again it says no device found.
m7_WLV PVT SHIP S-ON RH
OS- 1.10.605.8 (1.10.605.10)
so now it only boots up into the bootload
when i try to unlock+S-OFF it says so devices found
and when i try to flash the RUU and type 'oem rebootRUU' this shows up
"bootloader) Start Verify: 3
(bootloader) SD: write failed in CMD25.
OKAY [ 1.492s]
finished. total time: 1.582s" (phone goes off!)
Here is how to fix it
Download this RUU file which matches your hboot
then put the file in your fastboot / adb directory, and rename it to Rom.zip
Put the device in fastboot mode
(Volume down and power until menu appears, select fastboot using power button)
Connect the device to the computer
Enter the following commands from terminal/command prompt in the fastboot directory, one at a time:
fastboot oem rebootRUU (this puts the device in RUU mode)
fastboot flash zip Rom.zip (rename file to Rom.zip)
It will say that the update did not finish, to flush again, so repeat the above step:
fastboot flash zip Rom.zip
Then when it finishes, type "fastboot reboot"
PS - NEVER s-on your phone. You do not to be s-on for ANYTHING. But being s-on will stop you from doing pretty much everything. The only reason to EVER revert to S-on is to send your phone in for a warranty replacement.
As soon as you finish those steps, go ahead and use rumrunner for your hboot version to get s-off again. Once you are s-off, you can take all your ota updates to get the newest firmware / stock rom, then flash a custom recovery through fastboot, and flash superuser or a custom rom from your recovery. You NEED s-off though. If you were s-off now this would be a simple fix, just flash firmware / recovery and a rom, but since you are s-on you are going to have to go to the matching stock RUU for your bootloader, and start from scratch. Hope i helped.
