[E1] Bootloader Unlock Problem (important!)

So. I would like to unlock the bootloader. All fine, I get the code, and when I type in
Code:
fastboot -i 0xfce oem unlock 0xcodehere
it says
Code:
FAILED: Command did not succeed.
However, when I do it the second time (enter the command right again) it says OKAY but the device will end up on a bootloop next start, and when I try to flash a kernel, it says not allowed.(fastboot) If I flash when unlocked without restarting device, the device will shut down at SONY logo. Is it possible that I got a temporary unlock? How could I unlock the device successfully?(permanently) I tried it with Flashtool, and the same results. I literally tried everything. I also cannot install the permanent OS-independent CWM because of the shutdown at the SONY logo. I didn't yet contact my service provider, but I don't think they would like the idea. I really want CyanogenMod on my device, and I'd also like to fix some problems if I can. Please try to help ASAP. Thanks!

I have the same problem. Did you resolve it?
Open Phone and dial *#*#7378423#*#* go to Service Info->Configuration if Rooting Status says Bootloader unlock allow: No you can't unlock it. If it says Yes go to Sony's official website for unlocking and follow the instructions.
Good Luck.

Bootloop Mi4C please help

Hi all,
I really need some help. I was trying to update my Mi4c to MIUI 10, but something went wrong and now I it is in bootloop. It is locked and I can't unlock it anymore.
Since Fastboot is working I tried to enter EDL mode via ADB but it says this
PS C:\fastboot> .\fastboot devices
ecc1a647 fastboot
PS C:\fastboot> .\fastboot oem edl
...
FAILED (command write failed (Unknown error))
finished. total time: 5.002s
Please help,
Thank you
why not you try to flash the miui rom using fastboot mode instead of going to EDL.
You can get the rom file from this url https://mifirm.net/model/libra.ttt

Fastboot commands not working. Anyone please help

When i type
Fastboot flashing unlock
Fastboot oem unlock
Or anything and press enter
Fastboot interface exits itself.
And command gets failed
I get this message
FAILED (command write failed (no error))
finished. total time: 0.003 sec.
Anyone please help.
Try enter bootloader (Fastboot Mode) using adb command on Home Screen and make sure EOM Unlock Enable on Developer Options.
adb device -> Make sure Device Detect
adb reboot bootloader -> Reboot to Bootloader
Click to expand...
Click to collapse
If same Error try reflash current version firmware and try again.
I have tried
Still no fastboot command working.
Try change your Adb and Fastboot

reflash current version firmware or reset to Factory and try again.
Thanks a lot
