Hello. I have an I.TIM branded Atrix MB860 and I want to unlock The bootloader to install a custom recovery and a custom ROM.
How can I do?
Thanks in advance
If U want unlock bootloader search for file intl-fix-try1.sbf download it and flash with rsd lite, now boot phone in fasboot mode and type ''fastboot oem unlock'', cmd should display long numer which is device ID number) now type ''fastboot oem unlock xxxxx'' (xxxxx is ID of device) and after few seconds ''fastboot reboot'' now phone should reboot and at startup display ''Bootloader unlocked'' , after this flash cwm or other recovery and U can flash some custom rom.

Hi,
I have unlocked my bootloader officially through the unlock tool and wanted to flash a custom recovery and also root my device (Redmi Note 3 - Snapdragon).
I was on Global Dev (6.5.19) before I even started to unlock my bootloader.
After unlock, I was succesffuly able to flash Cofface TWRP recovery through fastboot (well the command prompt didn't throw up any errors and had a success message).
However, when i reboot into recovery (either through button combination or "adb reboot recovery", I just get a screen that shows an image of a phone and USB cable" (similar to the image on the official bootloader unlock tool.
I checked whether the bootloader was unlocked (fastboot oem device-info) and it was indeed unlocked.
I have factory reset and reflashed 6.5.19 (Global dev rom) with MiFlash and this hasn't made any difference.
I also relocked the bootloader with MiFlash Beta and then unlocked successfully with the official unlock tool.
All of these steps still haven't made a difference.
Can someone please advise on the next step to do (as unlocked bootloader is pretty useless if I can't install a custom recovery).
P.S. I also get the same phone and usb cable image when booting into stock recovery
find it weird problem
if you dont,then first just boot the recovery
code:- fastboot boot xxxrecovery.img where xxxrecovery replace your own recovery img name in fastboot folder.
you must success and see twrp recovery
then again transfer img to sdcard and to flash from recovery.
then flash it from recovery and when you reboot ,just swipe to diseable rom to replace it with stock one.
find it really weird ,i did it hundredths of time in my offi unlocked and every time goes fine flashing recovery from fastboot
Hit thanks if i helped
please follow this... it does help for me.

I have the same problem .How u solved your problem?
You can easily flash this one ZCX Twrp. Is the best i didn`t encountered any issue until now. I`ve flashed custom roms and miui roms as well.. The install process is very simple, follow this one https://forum.xda-developers.com/redmi-note-3/how-to/zcx-twrp-install-twrp-flash-supersu-t3462448
Hello!
Today i was trying to return to factory conditions on my mido (recovery, ROM, bootloader, etc) but i locked the bootloader with "fastboot oem lock" instead of doing it with miunlock.
Now i am unable to flash anything, from fastboot roms, to custom recoveries, to anything.
Is there any way i can try and revive my device? I tried using miflash, unlocking again with miunlock, all to no avail.
Thanks in advance,
Carlo
Try this
Boot into bootloader and then connect to pc install mi flash tool and then after downloading rom click on clean and lock
Solved by using miunlock version at this link http<colon><slash><slash>en<dot>miui<dot>com<slash>forum<dot>php?mod=redirect&goto=findpost&ptid=204866&pid=
I unlocked the bootloader succesfully (amazingly!), flashed the fastboot rom with miflash and phone revived!
Hope this can be helpful to people with my same problem!
how to root vivo Y17 android 9. I have done a variety of ways. but nothing worked
help me master
I have vivo y17 also
I tried to unlock bootloader using this codes:
fastboot oem unlock
fastboot oem unlock-go
fastboot flashing unlock
fastboot flashing unlock_critical
fastboot bbk vivo_bsp unlock_vivo
Bootloader still locked, so no point of unlocking bootloader
I have theory, might not true, if you install the stock rom of the vivo (yours) and modify some files
Then you manual wipe data, and manual install software that has been modified
I not yet tried that yet
I also have vivo y17 1902
I also try everything from fastboot to every tool to unlock bootloader (fast boot commands also)
Nothing work for me
I think it not working because get_unlock_ability is set to 0 by manufacturer and Turning on OEM unlock will not make get_unlock_ability to 1 and it's because manufacturer is permanently lock bootloader.
I have idea we can just replace stock recovery from firmware to custom recovery (twrp) simple then we don't even need to unlock bootloader and we can flash magick .

I was unable to flash aex rom and so I flashed stock rom through twrp and now I am in realme UI with a stock recovery but an unlocked bootloader. and when I try to relock bootloader by using "fastboot flashing lock" or "./fastboot flashing lock" in my pc it just shows a list of commands.....what do I do?
Hi, so several months ago i installed MIUI 12 weekly to my Xiaomi Mi A3, and now I wanted to upgrade to the stable release. When i was flashing a boot image file, after restart, my twrp dissapear. I tried to flash the rom using Mi Flash on PC, but i touched the cable and the phone disconnected, locking the bootloader in the process. I have no OS, my bootloader is locked. Is my phone truly dead?
I also forgot to uninstall Magisk root from my phone, so it's my full mistake. adb doesn't recognize my phone. I can only turn on the phone, leave it on boot until the battery drains, or the fastboot. Is there any chances that I can save my phone?

I can't. It says i cannot flash while in Lock State. Basically i can't do anything without unlocked bootloader.
well unlock it, you have 2 comands to put.
fastboot flashing unlock
fastboot flashing unlock_critical
FAILED (remote: Token Verify Failed, Reboot the device) after i used the commands you told me.
What should I do next?
And Mi Unlock tool can't unlock the device, because I need to change some settings in Developer Options, and I have no rom.
did you try switching slots?
fastboot getvar current-slot
Getvar Variable not found
f###,
then only some recovery option with
mi tools.
Download mi a3 platform tool file then download fastboot and fastboot unlock critical file paste these both in platform tool folder then plug device through fastboot to pc then first click on fastboot unlock and then fastboot unlocking critical it will be unlocked then install the rom through mi flash
