hello everybody

I've Flashed my Xperia P with kernel Nemesis_XP_v6.3[ENIGMA]

to recover a backup I've made before in this kernel

after flashing I can't recover CWM backup , it send me MD5 mismatch although I didn't do anything for CWM folder

then I tried to turned the phone off to flash the stock ROM again

but the phone can't turned off !!!

I tried to force shutdown with the power key and volume up for 10 sec then finally the phone turned off

I tried to flash the stock ROM but the phone can't boot to flashmode or fast boot or even boot when it's connected to PC

also I tried to turn it on but it can't with the power button only !!

the phone turn on with "power key + volume up"

please help me what should I do here ??

the phone when is turned off normally you can connect to PC with any mode.

but when I turned it off using Force method (power key + volume up) the phone doesn't respond to any connect to PC !

also it can't be turned on normally (by power key only) !

only when I pressed (power key + volume up) = (the same shutdown method) it turned on

and now I don't know how to let it shutdown normally to flash the ROM

yea , I think the main problem is the battery was drained because after I flash the kernel and can't restore the backup I turned it off from CWM well and plan to flash the ROM but in a moment I decide to turn it on to try to wipe data/Factory reset maybe I could restore the backup .

but the same I couldn't , so I decide to turn it off and flash the ROM , but I couldn't , the phone was not able to turn off from CWM as I did before .

at the end the phone was turned off due to the battery was drained

so I connect it to charger for about 3 hours but as the phone doesn't charge !

and now I'm so scare that maybe the battery or the phone is damaged ..... !

finally the problem is gone

my friend disassembled it and removed the battery cable then re-back

then the phone is able to be charged properly then flash the ROM
