Hello,
I have a galaxsy s5 906k and I've been reading on how to unlock the bootloader as I'm trying to install Remix OS and it seems I've come across a lot of misinformation.... and if possible can someone tell me what exactly I need to unlock the bootloader, as I can't find a list of the appropriate tools? Do I need twrp for my specific device?? Some have said yes and some no.
My phone is already rooted.
Also post unlock bootloader question, can I use the 900k rom from remix to install on my 906k?
EDIT**
I can only boot into download mode, not fastboot mode. adb devices returns the device, but fastboot devices returns nothing. Tried adb reboot-bootloader`and it just shows waiting for any device.
These all boot into download/odin mode!!!!!!
adb reboot download
adb reboot bootloader / adb reboot-bootloader
fastboot oem unlock
fastboot flashing unlock
Only one that boots into recovery mode! Then I go to Reboot to bootloader and it comes back to recovery mode!!!!!!!!!!
adb reboot recovery

Hello.
Long story short:
I have a OnePlus2, I can boot in Fastboot mode and my PC does recignize the fastboot device.
fastboot oem device-info says that Bootloader is locked and when I try to unlock (fastboot oem unlock) it states "okay" but cannot boot into system because there is none installed. -> Bootloop
I cannot boot into recovery nor install a recovery due to the locked bootloader.
My Question:
Is there a way to unlock the bootloader in fastboot and/or install a boot.img?
I am happy for any help that I get.
Have a good day/night

No, but why you don't have system?
You have stock recovery download official signed full zip and flash it. Recovery.
Also unbrick guide using the one you need Qualcomm drivers

I stupidly flashed a wrong file and lost access to twrp and root. But that is cool I got back ups etc because I was in the process of rebuilding anyway
Symptoms :
If I restart phone it'll get stuck on logo until
Fastboot continue
OS loads up but....
No root and no access to bootloader, can not fastboot flash recovery recovery. Img
Failed Device is locked
Cannot flash anything onto it seems I am locked out an unlocked then locked bootloader without root??
See attachments for more details
Is there a way out of this mess, lol what have I done :crying:
Just to clarify I have adb enabled, cmd promt and terminal have access to it under abd /fastboot devices = id, I just can't flash anything so is there another way to get root and install twrp if I can't flash?
I can't seem to get ADB or Fastboot working in Recovery or Download Mode.
In recovery if I select the option 'install update from adb sideload' then my device shows up is adb (not useful to me right now) but not in fastboot, which is what I need to execute the 'fastboot oem unlock' command (is that the right way? I've already enabled oem unlocking in settings). I can flash files via Odin, do I need to flash twrp or something?
Any help would be appreciated!
EDIT:
So it turns out that the toggle 'allow oem unlocking' unlocks the bootloader. The reason i thought it didn't was because when I flashed the cf-auto-root file I got stuck in a bootloop. Turns out I had to flash the file, then go into recovery, then reboot which solved my problems.
Samsung devices do not support fastboot mode.
The device is already OEM unlocked. You should be able to boot into Download or Odin mode and flash pretty much anything.
ODIN only
Can anyone point me to a guide for re-locking the bootloader and going back to stock on the A2017U? Right now I'm on the universal bootloader with TWRP recovery and LOS, but I need to send my phone in for warranty service.
I tried ADB flashing the stock recovery, which I extracted from the A2017U B15 update on ZTE's support page, but the phone gets stuck on the ZTE splash screen when trying to boot to recovery to flash the stock B15 update. Any guidance here would be greatly appreciated.
Use one of the stickied threads to reinstall stock
Then boot into fastboot and use this command:
fastboot oem lock

Yes, you are not on fastboot mode...
Another way would be to use axon7toolkit, it should install a bootloader image with fastboot enabled if you don't have one
what i messed up?
i have installed custom official cynogen14.1 rom and twrp recovery. everything was working fine.
but i messed up with bootloader. I have locked oem from fastboot mode without enabling option for oem unlocking in developer settings.
Now as my phone have custom rom and twrp installed it went into bootloop and only shows zuk logo and again restart.
What i diid till now?
i have opened backcover so that i can turn of bootloop and phone by disconecting battery.
I can enter into fastboot mode by pressing vol.+ and vol- buttons sumultaneously and connecting usb cable.
But i cannot unlock bootloader as it says unlocking bootloader not allowed. I have tried device specific commads like "fastboot -i 0x2b4c oem unlock" and "fastboot -i 0x2b4c oem unlock-go" but nothing works.
i have stock recovery image but cannot flash while bootloader is locked.
i can enter into adb sideload by following method:
by loading stock recovery by typing "fastboot boot recovery.img" (this does not work with twrp as it says signature varification failed)
and then selecting apply update >> selecting apply fron adb
this much i can do does anyone knows how to recover from such a state.
please help me or my phone will be a waste.
is there any way to install stock recovery i think phone will boot properly if i managed to install stock recovery.
