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!)
