Hello, I want to unlock my bootloader on my phone, but I don't have bootloader unlock code and i don't want to pay for any service and I just wanted to know if it's possible to unlock bootloader with custom firmware or just install custom recovery (TWRP) i know it's possible and i had tried it but idk how to open EFI.img in UPDATE.APP, and in 7-Zip it just says "Unsupported data format". So is there any program that can open it and change data?

Hello from Greece.
I have a Doogee X5.
Firmware: DOOGEE-X5.2016/05/04
Kernel: [email protected].2016.05.04
Version Nr: DOOGEE-X5-B-Android5.1-2016.05.04
I want to install custom rom. Cannot install custom recovery, due to locked bootloader. adb oem unlock ????????????????
Do i need a 16-digit code, or can i unlock it somehow?
Every time i unlock it, it automatically wipes data/factory default.
Maybe i don't know via flash tools.
Thank you in advance.

The doogee x5 is a device that use mtk(mediatek) processor, and so you don't need to unlock the bootloader. You can flash a custom recovery with spft(SP FLASH TOOL), or if you can root with an app you can flash custom recovery with mobile uncle MTK tools
What is mobile uncle tools ? The secret engineering mode menu ?
Do you have something like: Go engineering menu > find OEM Unlock
OEM Unlock should be ticked
After that, you should be able to flash stuff
Hi guys. I have few questions for you and would be happy and very grateful if you could answer and help me. First of all i have huawei P10 lite which i have bootloader unlocked it, installed twrp and also rooted. I also made backup of the stock rom with twrp. Now i want to restore my phone as new, i mean i want to get back to the stock rom which i made it with recovering but now how can i delete twrp and then lock bootloader? I saw that i have to use img file to delete twrp recovery - The model number is WAS-LX1 and the build number is WAS-LX1C432B124. I wasn't able to find this firmware and i am stuck now. Can i use other firmware for the model number WAS-LX1 or i will brick my phone? How to resolve this issue? I want to get back to stock.. Please help me..
Also is there any way to turn off the warning that says that the bootloader is unlocked and the device can not be trusted or just hide it? I tried to flash logo.bin file but it didn't work for me.
Thanks a lot guys.
Install recovery image from another firmware for WAS-LX1C432.
You can relock bootloader via fastboot using your code and the proper comand. This would get rid-off warning screen. All the info of firmware and oem info must coincide. Otherwise system won't boot unless you unlock the bootloader again.
Hello together,
i bricked my device. Unfortunately now i have bootloader unlock and frp locked !
i cannot install twrp anymore.
can anybody help me with a solution `?
please
Flash stock firmware, once you boot stock, go developers options and enable oem unlock
cannot go back to stock rom... phone locked frp locked, not possible via fastboot to unlock device anymore.
booting into phone is also not possible. and firmware downloading via erecovery failed.
please need help !!!
You could up grade your Phone vía dload o sdcard, when you put the firmware in the sd or internal, it auto flashes, Just flash the signed firmware for your device
ok guys so my dad has bricked his nokia .8.. i managed to get Twrp working again. and that's about it.. the bootloader is unlocked but i cant can't unlock "bootloader critical" it says something like " (remote command not allowed)" when i check the device info it says bootloader is unlocked but bootloader critical is not.. iv tried flashing via the ost but it says i need to unlock the critical bootloader..
another problem is that i cant flash in twrp. it says invalid zip file or something...
has anyone got a Twrp Backup they could upload so i can try and get this thing working again? or a zip i can flash via twrp?
cheers.
Did you do "fastboot flash unlock <path to unlock.key>" before trying to execute "fastboot oem unlock_critical"?
Did you maybe have an unlock key that was generated through the unofficial unlock (every build before august 2018) and are now on a newer build that supports only the official unlock?
If you can't manage to unlock the bootloader to critical, get some stock boot image (I have some at https://bit.ly/nokia-nb1), flash that to your active boot partition in fastboot (overwrite TWRP with it), then boot into stock recovery and sideload a full OTA package (which will restore all partitions that might be corrupted). All 1.5 GB files you can see in the OTA folder at the link I posted are full OTAs and will work.
ok so just an update i managed to get a rom on there, i found the right key and did the unlock all over again.. all booted ok, problem now is that i have no signal... i cant send any mssgs or phone calls. i tired to update the smsc. via this *#*#4636#*#*. and going phone info etc, but it says update error, iv also tried the encoded number for ee, but still says update error. i can put the sim card into another phone and it will send messages etc, i did read that i could update the smsc on a diffrent phone then put it back into the nokia and it will work, but it did not for me...
again there was another video showing how to fix this via backing up the firmware folder on rom then replacing with the one that dose not work . but ... i dont have a rom that works lol . iv also tried to install diffrent roms or systems and still the same problem.. i use the NOST tool. to update the firmware
any advice????
also this is his account hence a diffrent account name lol
cheers
After using the motorola smart tools and trying to flash the smartfone
the device only starts up to the bootloader
the bootloader is locked
I'm not in the recovery mode he always jumps back to the boot loader.
if I connect the device to the pc then it starts without turning up in the boot loader.
is there still a solution, or do i have a new paperweight

Did you try blank flash yet?
Forget everything, and try to manually boot into TWRP.
Download TWRP for payton from the TWRP site (Img and Zip files for V3.2). Download and install Minimal ADB, Copy TWRP img file into the ADB install directory, put your phone into bootloader mode, connect to PC and run "fastboot boot twrp-3.2.3-1-payton.img" on the ADB commandline. The phone will boot into TWRP. You'll have to mount the storage and copy the TWRP .zip file into your phone and flash that from TWRP. Now you got TWRP flashed as the recovery.
Now it's a matter of flashing a ROM. I'm not really sure about stock firmware because i haven't flashed them before, but if you want to flash a custom ROM, make sure you flash TWRP after flashing the ROM without rebooting into system or recovery.
PS: I assumed you know how to do this with this explanation. Let me know if you need more instructions.
the bootloader is locked and I cant unlock them
because oem unlock option is not activ
the last time my pattern was requested, nevertheless
I havent access to twrp. it was blocked
is there another option?
