I tried to relock my Xperia V (unlocked BL) with latest version of flashtool (v.0.9.16.1) and it seemed successful.
After I unplugged the cable and rebooted my phone (It had a normally working stock FW of 9.2.A.1.120), it stucked right after the SONY logo for some minutes and powered off automatically
And now every time I try to power it on, it does actually the same thing:
1. shows the SONY logo
2. shows this.
and stays for about 5-10 minutes.
3. becomes blank screen and does not try to boot again.
As it could be set to Fastboot Mode and Flash Mode, I also tried to solve it but of no use. Here are my attempts:
1. Using PC Companion or SONY Update Service to repair both results in failure
2. Using Flashtool to flash FTFs gets following error messages
ERROR - ERR_SEVERITY="MAJOR";ERR_CODE="0026";ERR_DYNAMIC=" 08 : TA flush failed";
3. Also tried to re-unlock the relocked BL...
On the first time of trying after a reboot, the fastboot.exe says: FAILED (remote: oem unlock failed!)
and on the following attempts it keeps telling me: FAILED (remote: Phone is already unlocked!)
(but actually it's still locked)
Now I could neither flash anything into it, nor unlock the BL...
Totally confused about this situation. Would relocking BL brick a phone? Is there any solution to this?
