[bhavstech]

first i tried to unlock bootloader it showed me failed in pc!
but when the phone booted the bootloader was unlocked and it showed unlocked too in fastboot!
i tried to install recovery it worked fine!
then i took a backup ,clean wiped and installed resurrection remix but it went in a loop!
then i tried cm12 build april 7 that too went in a loop!
after that when i restored nand backup it worked fine!
So where am i wrong?!

are you on 4.4.4 or 5.0.2?? I mean did you update your rom to soak test lollipop using zip file??
If you try to install 5.x roms over 4.4.4 stock rom you will likely to get loop
try installing cm11 stable version first then install cm12 over it

It's the same on Moto G (2014), to flash 5.x.x ROMs, you'll need the lollipop bootloader... if you have a 4.4.4 bootloader, you will get bootloop.

If you update to soak test, your bootloader will be updated.
