Xperia v boot problem

vibogd · Apr 28, 2014

Hi, i have xperia V (protoype). It was working fine, until i decide to put new Android (i was 4.0.4 on it). I don't have much of experience in flashing, but i did success already with my two other phones (ARC and P ), so i thought this time will be easy as usually. but...
phone was dead as stone..i spend more than week to trying all methods what i was able to find. now it's a big mess in my head and my PC, but now i made phone to start in recovery menu. thats all. tried install different roms, cyanomodgens-nothing... it just shows me SONY-->cyanomodgen and freez. at the moment flashtool can't see my phone.
if anyone can help me what to do( step by step), how to make this phone working again -i will be very happy person.
sorry for english.

Try a clean install :

Wipe Data + Cache + System + Dalvik

just make it clear.. is it menu when need to press volume button when "sony" appears on the screen?
i can't tell you exactly how i did it- i did it with flashboot (boot.img or something), don't remember. didn't touch the phone for week, because i don't know what and how to do. as i said, i need step-by-step advice from beginning. if anyone will help me-i will be sooo happy

1. Is your bootloader unlocked - and did you test if your BL is/was unlockable?

If BL is unlocked correctly:

2. Try to flash another kernel in recovery,such as http://xdaforums.com/showthread.php?t=2223534
Then try to install a CM-ROM for example.

1. i did kernel install
2. CM install shows me some errors. can you drop me link for rom, please?
p.s. tried another CM-and again: "sony"->"cyanogenmod"->blank screen (phone is on)

We cannot help you unless you answer our questions correctly.

BL unlocked correctly?

Already tried another kernel?

well, i did unlock ( i was thinking i did it-got code, entered it). and now i got message on flashtool
- Reading device information

when i do that "fastboot.exe -i 0x0fce oem unlock 0xxxxxx" it says "phone is already unlocked! "

yes, i tried different kernels.

there are so many files with *.img, sin, elf, ftf -i don't have clue what has to be done.

when phone was OK i checke in service (?) menu and it was "bootloader unlock allowed-yes"

i'm trying to answer as much as i can.

That sounds strange - because you said that service menu allowed unlocking bootloader. To be honest, I don't know what happens if try to unlock a bootloader which is not unlockable.

Regarding flashing: Take the NKernel from my link, open the ZIP file and extract the kernel.elf.
Then flash elf file via fastboot: fastboot flash boot kernel.elf

And then try to get into recovery and then try to flash a CM ROM like this from your external SD: https://download.cyanogenmod.org/get/jenkins/39793/cm-10.1.3-RC1-tsubasa.zip (10.1.3-RC1).

It's in #7 where I asked you the first time to try another kernel!

http://xdaforums.com/showpost.php?p=52279445&postcount=7

Try installing the ROM with NKernel recovery, otherwise you can flash the boot.img from the CM ROM (inside zip, also via fastboot). Can you install the ROM with one of the kernels?

ok... i installed kernel.elf, when i reboot into recover mode i was unable to choose anything-touchscreen doesn't respond, buttons does nothing aswell.

i'm sure i do everything ok, but every time phone stuck on second screen after "sony"
after flahsing boot.img phone stuck on first screen"sony"
p.s i don't know if that is important, but almost every time pc trying to instal drivers, but...MTP drivers was not instaled

That's normal, you can't boot a CM Rom with NKernel (which is for stock 4.1). You always need the right kernel for every Rom (and Rom generation - a CM 11 kernel won't boot with CM 10.2).
It was just to test if recovery is working. But you say it doesn't respond? Of course tochscreen is not working in CWM! You have to navigate with Vol up/down and enter via power button. I hope you know that?!

Go ahead and try different kernels/Roms. Like this: http://aokp.co/devices/tsubasa
Install boot.img from zip via fastboot, go into recovery and try to install the AOKP Rom from your externel SD card. Does recovery work? Can you install Rom?

yes, i know have to use vol + -, but noone button works.
one more q.. it doesn't matter prototype phone or not? uufff.. i'm almost give up. looks like i'm doing same and same every time and no effect.
thanks for helping and not leaving me alone with that head pain

p.s. just installed boot.img, but when tried to run recovery-just dead androbot appears on the screen

dyfk3l · May 1, 2014

Sorry, but I've got no idea.

I never had the problem that a flashed kernel's recovery is not working - and I don't know why. Sorry.

Must have to do with the Flashtool message that your bootloader cannot be unlocked. There is sth. really strange...

I suggest to flash stock ROM and then relock your bootloader
