Hi, currently on carbon 4.4.4,unlocked bootloader on xperia zl, unlocking is simple using flashtool once u have imei #.instead of using above steps from cmd,connect the usb to phone n laptop, just click unlock button from tool,turnoff the phone, come back in flashboot mode using volume down key, it will flash,turn off the phone n connect in fastboot using volume up key, put the imei number n unlock. It will save the file n using same file u can relock later.: -)
In the above steps, instead of imei #,it should be bootloader key. Sorry for confusion
Unlocking is now an easy job…
And relocking service gives us more power to perform more testings, developments n hackings.
So my question is “Does this official relocking service restore DRM keys (TA partition)?” I mean, we all know unlocking bootloader loses DRM keys in TA partition.
It’ll be great for those who didn’t back up TA partition before unlocking BL.
After unlocking bootloader if i flash original ftf then will bootloader relock???
what about xperia e1 dual, not listed under device. So, how to unlock this device, any suggestion. Thank you.
