[YU Yuphoria] ajaykumarsapra:
Hello [MENTION=5641921]Naman Bhalla[/MENTION]

I use YU Yuphoria 5010 since more than a year with original cyanogenmod updated via updater to 12.1 without root and locked bootloader.

Since a month i have been facing force closure in many apps so i downloaded the cyanogenmod 12.1 reovery rom and did dirty flash via recovery solved settings app force closure but not all FC. Then I decided to clean flash a custom rom since cyanogenmod is closed now and also lineage and Yuos have no Volte support.

For this i read many posts forum properly unlocked my Yuphoria with Doomlord's method then rooted it and then flashed TWRP 3.0.0.0 on it and then did clean install of MIUI by Gaggu,and then Rohan successfully and used them but volte was not working. Then flashed stock rom by Yukick and everything (volte + vilte) was working fine exceptfor phone shutting down at 40% of battery.

Then decided for resurrection remix (5.8.1) and flashed it successfully. Tested it for three days some force closure were there also Vilte (not Volte) also not woking. Then saw a RR update (5.8.2) on resurrection remix download page for Yuphoria downloaded it and first time done a dirty flash (every previous flash was a clean flash this time I thought i am already on RR so no problem should be there).

There starts my problem the phone stuck at YU logo then tried to enter the Twrp recovery but could not. So flashed twrp via fastboot again and then wiped cache, delvik cache but no use could not start the phone. so tried to clean flash original cyanogenmod 12.1 rom ( that i used as for dirty flash many times to rectify some fc before) but could not.

Then read many threads on Yu forum and XDA forum and tried many things but no use.

Now the present condition is i can enter Fastboot mode by pressing vol up + power button with

cyanogen fastboot written on screen and can execute various fastoot commands but cannot flash rom as

Fastboot -i 0x2a96 flash system system.img

fail to write system.

I can't enter recovery with vol down + power button (after i entered the command Fastboot erase recovery previously i can enter the recovery by pressing vol down + power button, I did so to replace the TWRP with CWM recovery but no success) Phone starts YU logo appears for some time and then Blank screen.

But i can enter recovery via Fastboot with command

Fastboot -i 0x2a96 boot twrp_3.0.0.0_lettuce.img

but in twrp cannot mount system, data and cache partition tried various things like full wipe and repair file system change file system but no use. Twrp shows intenal storage 0 mb. also cannot flash other custom recovery if i try to flash other custom recovery via fastboot it says ok but cannot boot into recovery but when tried to enter via fastboot command phone enters in cyanogenmod recovery. it can also boot in recovery of Fastboot stock rom via fastboot command.

Fastboot -i 0x2a96 oem device-info

shows

device tampered false,

device unlocked true,

Charger screen enabled true.

I can lock the bootloader also by command

Fastbbot -i 0x2a96 oem lock

then device-info shows

device unlocked false

(without bootloader restart if restarted it shows device

unlocked true).

when enetered in TWRP 3.0.0.0 via fastboot command the phone is also shown as MTP device in Windows but only memory card is shown as storage no internal storage.

if i try to start the phone by pressing power button it stucks at YU logo.

if i connect the phone to computer while it is poweroff it is shown as Android Phone (Android

bootloader interface) in Device manager on my windows 7 laptop.

any other information or screen shot if needed I will provide.

Will you help me in booting my device back.
