Hey everyone, I just unlocked my bootloader, only THEN to read that after doing so, I lose something called 'DRM keys'. And now my phone is refusing to boot (soft brick). I fear re-installing the android OS will permanently make me lose these keys, as I never had the chance to back them up. Is there any way I can still get these keys back??? AND ANY WAY TO GET MY PHONE WORKING?

PLEASE respond ASAP, I need to make calls with this phone for my job.

Ok I see your phone is on bootloop... you have to flash stock firmware if you don't know what file was removed/modified who knows haha :P

Download the latest FTF file for your device, check here Xperia E Official Thread [ROMS, MODS, ROOT, FTFS, HOW TO]

You have to flash that file with FlashTool, if you don't know how to use this, check here [TUTORIAL] HOW TO FLASH STOCK ROMs WITH FLASHTOOL is for XZ but it's the same procedure for XE and all sony devices...

Finally DRM Keys...

Quote:

Some time ago, we talked about the importance of backing up the TA partition on Sony Xperia devices. Doing so on Sony Xperia devices saves your DRM keys. Why is this important? These keys are required in order to use a few proprietary software bits such as Bravia Engine in the Gallery app and OTA updates.

Hope you can get back your device, have a good day / night!

Reflash stock FTF - that always works.

Oh, wait... MatsPunt's guide tells you to do exactly that... whoops.
