UPDATE on UBL
Hi Everyone, yesterday i tried to unlock with 2 ways, the first way is with the SONY Official method even though the phone doesn't boot, i can get the IMEI from the back of the phone, and from the BOX (which is basically the same IMEI) and got the code from SONY. but unfortunately every time i'm in the final step i got : Remote oem unlock failed. And i'm sure i'm updated and using the latest Android SDK. i even tried to do fastboot command from other laptop but the problem still there. (Tried to google it for the same questions like that but what i got is only people that had a mistake in inputting the code number) Note: I already cross checked it for many times, that now in my inbox i had 5 same codes from SONY
Next is the Test Point with s1 tools method. But like always in the final step, i got another error which is: test point qcreceivepacket can't get packet start i tried to google it again (which is always leading me to XDA cause here is always the source lol) many people answered that same questions which is because the Xperia you're trying to root got a new version 2012 and something like that.
Note: I'm pretty sure the Xperia Ray i'm unlocking is Bootloader Unlock Allowed: Yes, because when it's still alive i already checked it via *#*#7378423#*#* and 1 more thing is because i already tried to unlock an Xperia Mini Pro that is Bootloader Unlock Allowed: NO. Which is really can't be unlocked because the phone with that kind of status can't go to fastboot (always go to charging mode instead)
Maybe you can say i had a lot of experience with Android, but i'm just creating the forum account yesterday, so i'm still a NOOB here
which is why i appreciate all the help from you guys.
I'm gonna try Contacting the top Xperia developer (which is i still don't know how) ASAP
EDIT: Just read someone questions on Q/A General chat thread. That the reason i'm failed is because i haven't rooted my phone? Is it true to unlock you need to have a root access first? cause in my other Xperia (Active, Sola) i always root first before unlocking so i don't know if unlocking first will do.
