[Q] [HELP] XPERIA P - Update failed during process [SOLVED]

I tried to update my phone to JB 6.2.A.1.100 using Sony PCC. Download process was successful. But, when I was on update process (about 50%), PCC was not responding and closed.

[Q] Untypical Xperia Z brick

Hi, I know there were many similar topics but this case looks different. I've tried to update my xperia Z using PcCompanion (to newest available kitkat) during flashing i got an error and all I saw after turning it on was grey triangle with warning. PC companion see my phone but cannot repair it (I got error 100), during flashing three different OFW in flashtool it always stucks on kernel or system flashing (excluding them in installation make possible for flashtool to finish the job) It gives constant blue light in fastbot mode but when i'm connecting it in flash mode it only blinks green and then red for a second each and remains black. I can make force shutdown only when it's in charger and being in charger it only blinks with red light and when I want to turn it on it only vibrate once and do and show nothing. It's not rooted, has locked bootloader and battery over 60 % full. Does anyone may help ?

[Q] Xperia Neo won't start

Hi. My xperia Neo crashed, I tried to send a photo via bluetooth and the phone just turned off. I tried to turn it on, it appears the "SONY" screen, then the "XPERIA" screen, and then it restarts, over and over again with the same 2 screens. I searched topics, they say that I have to flash it, but I can't start the phone in flash mode, with power and back buttons, any software (Companion, flashtool) don't detect the phone. Is there any solution?
Just like death

Hi, I´ve got similar problem. A year ago my Neo V went dead (I thought so). Just for fun, I tried to connect it to PC yesterday and what happened? It started charging and after few minutes I started it (YAAAY)! So I thought It was just some bug that disapiered after discharging. So I did a hard reset, to gain factory settings, repair the firmware via PCcompanion, everything was OK until I shove a memory card inside. After that it died again. Its not charging, no reaction after connecting to PC, no reaction on ON/OFF button, no reaction for button-hard-reset, no response while trying flashing with EMMA or FLASHTOOL, nothing... Does anybody knows what to do with it or do I have to wait again until it discharge and pray it would work after that?
help
I have the same problem as you did it to solve? :crying:

bricked z2 maybe?

hi, my bro gave a z2 but i dont know what the error, before starts the phone and stuck to sony logo xperia and nothing was happened, now only flash to the top with red flashes and didnt power up and not charging, only testing with pc, didnt have ac charger, i have win10 x64 maybe its another problem i think, any chance recoverying?
nothing to loose
Flash new ROM via flashtool, that's all
If it stucks at SONY logo, there's a softbrick i think
Either that or go on Sony Update Service and try a repair
