[Sony Xperia E3] mbc07:
Updates regarding the modded giefroot:

What variants are supported?

At the moment, only D2202 and D2212 (non-LTE ones). If you have a D2202 or D2212, just follow these instructions I posted before. In most cases, running the modded giefroot once will give you full root access. If it fails, try more two or three times and it'll work.

Help! I have D2203/D2206/D2243 (insert any other LTE variant here) and the modded tool doesn't work. What should I do?

From the many debug versions and possible workarounds, all of them failed. My last attempt in providing support to the LTE versions is the debug version v3 (attached below). Follow these instructions I posted before but use the debug version attached below instead. Run the tool at least 3 times and always save all output from command prompt/terminal console window somewhere (text file, screenshot, etc) then post it here. If the tool still fails, try another 3 times in safe mode (to enter safe mode, hold the power button then hold the Power off option -- a small popup should open asking if you want to reboot in safe mode). Remember, this version won't provide logs anymore, all I need is the output from the command prompt/terminal console, don't forget to post them here!

IF I can't get any useful info that may help finding the issue, I'm sorry guys but you'll be on your own, I won't support LTE variants, only the non-LTE ones. From a lot of reasons, the main ones is that I don't have physical access to a LTE variant (only non-LTE) to mes around and try experimental stuff and that all of my attempts in getting info that could help zxzO0O finding the issue failed.

You promised a proper thread with a noob friendly guide, where is it?!

As I said before, I'm not actively developing it because I'm trying to get LTE variants working. It's my last attempt, if it doesn't work, I'll drop support for LTE variants and will finish and release the guide for non-LTE variants only. Again, I'm sorry...

Unfortunately, dd Flasher is in beta stage and the error handling interface weren't ported from the old Nicki Root yet. Since you got errors during package install, something went wrong and the image didn't got mounted. This resulted in a corrupt system image being flashed in your device and that's why you got stuck in the Sony logo. Here are your current options:

1) Wait until I manage to release a stable version of dd Flasher to tell me what exactly went wrong and keep using the old 4.4.2 firmware. No ETA at the moment.

2) If you hadn't done any modifications to the system partition (other than getting root with the modded giefroot) yet and there's OTA updates available in your region, enable Pseudo Pro mode and OTA survival in SuperSU settings and then update the device through OTA. You should still have root access.

3) If your device's bootloader is locked but can be unlocked, root using the modded giefroot, use Backup TA to backup your TA partition, flash the latest FTF available to your variant/region, unlock your bootloader, flash a custom recovery, install SuperSU through custom recovery, flash official kernel and FOTA kernel from the latest FTF available to your variant/region again and relock your bootloader by restoring the TA backup you took earlier (it'll restore your DRM keys too and your warranty will still be valid). This will result in the latest firmware version available with root access...
