[Sony Xperia P, U, Sola, Go] bluelightkatana:
HELP!

I tried flashing the new official ROM (ST27i_6.2.A.1.100_O2CZ), (instructions followed all the way down) but i got this errors, and now it´s stuck in flashboot mode, but the OS doesn´t start, tried to flash the firmware again, but GOT error reading headers, every time i connect the cable i get the flashboot mode, without holding the keys or anything.

I had a stiock firmware NO ROOT and NO NOBOOTLOADER UNLOCKED, it was stock completely.

Had old Android 2.3

-also my volume up key doens´t work, so if the solution is using it it won´t work for me.

I selected the first boxes in wipe because i read wiping that ones is better to flash a new ROM,

INSTRUCTIONS I WAS FOLLOWING

3. how to install the newest Android 4.1.2 for Sony XPERIA Go ST27i

a) first of all, check your firmware version (if you already have the newest one, you do not need this tutorial)

b) download and install latest Flashtool from this article

c) download also latest Android 4.1.2 (mirror) for Sony XPERIA Go ST27i

d) paste the ftf file downloaded in step c) to folder „Firmware“ included in the XPERIA Flashtool

e) open the XPERIA Flashtool, click on flash and choose downloaded firmware, than click ok. Important - if you do not want to delete any data of your phone, just uncheck flashing userdata.sin file. All data will remain in your phone, but sometimes it can cause additional troubles. So it is better (and I recommend that) to do the backup of your personal data, than proceed with clean instalation and then restore your personal data.

f) turn off your phone and when Flashtool shows pop up window, connect phone to PC with holding volume down button

g) after few minutes all is done and your phone gets the new firmware

NOOT!!!
