Fiesta IC6

Hi, everybody,

I rooted my Fiesta Duo I6C China phone (Fiesta_I6C_V06_2015_1130) using Kingoroot app. It went well and then I got the brilliant idea of replacing kingoroot's su for SuperSU. I followed this tutorial (Step 6 was what I did) but I got distracted and forgot to install Super SU apk (Step 6.1). I rebooted and the nightmare began. I wasn't able to boot anymore, phone stayed stuck at boot screen.

Then, I made things worse. I decided to clean my mess by performing a factory reset using the built in bootloader (Android System Recovery <3e>).

What happened? well now I have a non booting phone that does not allow adb access because USB debugging is no longer enabled.

I am a linux-only user, with moderated skills, and I am open to suggestions.

fastboot can be initiated, and both phone and computer can see each other.

$ fastboot devices
0123456789ABCDEF	fastboot

Solution seems quite easy, isn't it? Install TWRP and then flash stock rom again. However, there is no information about this phone anywhere, or at least I couldn't find any. What can I do?

When I perform phone's own system check from the built in recovery, it detects the manually manipulated files (su, for instance).

When I try some other fastboot commands, this is what I get:

$fastboot oem unlock
(bootloader) Start unlock flow
FAILED (remote:
Unlock operation is not allowed
)
Finished. Total time: 12.030s

$ fastboot oem bootlog

$ fastboot oem mmcinfo

$ fastboot oem info
FAILED (remote: unknown command)
Finished. Total time: 0.007s

This is the phone: Fiesta_I6C_V06_2015_1130

Any help will be really appreciated.

Regards.
