Hi there,
I think i bought a fake Samsung Galaxy S6. But it works well, and it looks identical and has most of the futures of the real Galaxy s6.
As a fake Samsung phone, it doesn't have any Odin Download mode in it. So i tried to get into the bootloader via adb "adb reboot bootloader".
When i get there, i try to unlock the bootloader "fastboot oem unlock".
On the screen of the Phone i get a message about the fact im trying to unlock the bootloader etc. Press volume up to Unlock, Press Volume down to cancel.
The problem is, I can't press Volume Up for some reason, only Volume down. So i can't unlock the Bootloader to install custom recovery via ADB and finally install custom ROM.
Anyone any help? I can only access Stock recovery menu, some chinese test menu and the bootloader. Thats it.
Any help would be appreciated, i can provide any info you will possibly need.
grtz, Alex

Hello there,
I followed the steps in this thread http://forum.xda-developers.com/showthread.php?t=1710755. But, at the last step, after I typed in the code, the tablet tried to restart and stopped with two lines at the upper left corner: "Bootloader version JB-653b3d3 (unlock mode)" and "Bootloader VJB-653b3d3 (unlocked mode): starting fastboot use download protocol". Then it just freezed here with a big ACER in the middle of hte screen. I had to turn it off to reboot it. However, even it says the bootloader is unlocked, the combination power+volume down didnot work. It doesn't go to the bootloader mode. So has anyone got this issue before? Is there anything I did wrong? Thanks.

Power+Volume down is only part of it. It sounds like you want to get to recovery... correct. If so:
Press and hold volume down and press power until the tab vibrates.
continue to hold volume down and release power until the tab vibrates again.
move to volume up and hold until the tab vibrates a third time and release all.
You are in recovery.
Stock recovery is extremely limited.
You would be better served with a CWM recovery to flash ROMs.
This is done on the computer.
If you are looking to return to fastboot mode to flash a recovery, this is also done on the computer.
"ADB reboot bootloader"
wait for the tab to reboot
fastboot flash recovery C:\path\*recovery*.img
Hi I'm hoping someone can help or at least point me in the right direction if i've missed a thread, i'm on Windows 7 64bit.
I appear to be stuck in a boot loop on my original Shield Tablet, stuck on nvidia screen when i try to go into recovery mode i get the "dead android" picture.
I have tried to unlock the bootloader and i get FAILED <remote: <>, device shows up under fastboot devices command, device shows up as Android Bootloader Interface in Device Manager.
I've searched the forums and seen this problem but everyone else seems to be able to unlock easily, this is the same but no replies https://forum.xda-developers.com/shield-tablet/help/nvidia-shield-unlock-bootloader-failed-t3178865.
Any help anyone can give me would be appreciated. Thanks in advance.
Check the recovery images section for your device here: https://developer.nvidia.com/shield-open-source
Instructions to unlock the bootloader:
Unlocking the Bootloader
Your SHIELD TABLET may have shipped with a locked bootloader. To update the device,
you must unlock the bootloader using the following:
- fastboot oem unlock
- Press the "Volume Down" button to select "Unlock bootloader" option on device
- Press the "Power" button to confirm the unlock. Your device's bootloader is now unlocked.
Click to expand...
Click to collapse
You need to already have adb set up and the Shield connected to the PC to do this. If you don't have USB debugging enabled, this may not be possible, but you should still be able to get into recovery by booting the tablet with Vol- and power button (hold volume - and then just press the power button, don't hold both at the same time).
Yes I've tried that (I know the steps of unlocking the bootloader) that's when i get the FAILED error. When I try to enter recovery I get the "dead" Android picture.
Hi,
is it a problem to relock the bootloader ?
What steps do i have to do ?
Greetz
adb devices
Now, you will see a serial number in the command prompt window which indicates that the device is connected.
adb reboot bootloader
As the device booted into Fastboot mode, type the following command to lock the bootloader.
fastboot oem lock
Now, a confirmation pop-up will appear on the device screen. Use the volume buttons to navigate the highlight to “Relock Bootloader” and press the Power button to confirm it.
And after this, what will happen? Especially when you are rooted? Will it wipe all your data and can you start all over again, or will you face errors/issues/bootloops?
Person I wont just relock my bootloader. Your hash records are broken and you won't get working upgrades anymore, it's even the question if you still can oem unlock it again..... Besides this I don't know if, when you will brick your device, the msm tools still work. If you want to go back to stock better use MSMtools directly and go back to stock. https://www.xda-developers.com/how-to-unbrick-oneplus-nord-msmdownloadtool/amp/

Is this a safe method ? I dont want to brick the phone.... because i read a thread,where the relock ends in a bootloop..... THX
Im not test it but i have last week close BL on my O+ 8pro without any problem!
But before you close BL read this:
https://forum.xda-developers.com/on...de-fix-persist-img-loss-finger-print-t4125909
So i make it. And everything works without any problem.
If you have root remove it.
Flash last original firmware!
(so if you use patched boot.img you have now the "original" again!)
Then relock bootloader...
After that i test it with FP,Face Unlock and OTA update!
Everything is fine ...

This 10.5.11.AC01AA version is ok?
I've spent hours searching and cannot find a definite answer to my question. I see others have asked HOW to fix this issue, I just want to know if it is possible.
Is it possible to factory reset my device or not?
Bootloader is NOT UNLOCKED, and I am stuck on bootloader screen.
"Bootlinux Failed: Not started" when trying recovery mode.
"Slot Unbootable: Load Error" when trying to start.
My device is obviously not found under adb devices as it is locked, but does show up in fastboot devices.
My computer does recognize the android device as well.
Is it possible to factory reset my device or not?
Is there any way to flash a custom ROM and get it operational?
I'd say you're out of luck, I've had the slot unbootable error/ authload error and both usually require re flashing the bootloader, radio, boot.img or a full factory image restore via flash-all to restore via an unlocked BL. I haven't seen any other methods available for the walleye with a locked bootloader I can offer either.

Thanks for your reply,
Surely Google or some super nerd would know how? But I think I am also out of luck.
Thanks though.
Hi! I don't know if could helps, but did you try to sideload full OTA through recovery mode? This should be go with locked BL too, but I am not sure if you have to have enable usb debuging...

Hey Somin,
I haven't fully looked into that option yet, started to give up. But I can't access recovery mode or even get out of bootloader, and usb debugging is not enabled, oem is locked.
If you have any further information or ideas I would be really keen to hear.
Thanks,
Alex

Did you tried to get to recovery from bootloader screen or with key combination too?

I do appreciate your help, but as I just mentioned, I am stuck in bootloader screen and get errors when trying to access recovery, download, start or any other option. Obviously using the hard reset only brings me to bootloader where I am stuck.
Is this what you're referring to with key combination?

Hi! No Shut down your phone and try "the game" with power button and vol+ btn... I didn't find any tutorial and it is slightly lottery, but you could get directly to recovery mode if you will press this btns in correct way:
- try to hold them for long time
- try to hold power btn and quick pushing vol+
If you will get to "no command" screen, press again pwr+vol up and you should be in recovery mode. Good luck

Interesting, I get the same error message as I do when I try to enter Download Mode. So this is different than the power and volume down, and different than just restarting it.
So far I just keep getting back to bootloader screen saying operation denied. But might keep trying it here and there haha.
Thanks for your help.
I had the same problem. I was able to solve it by selecting the download mode in the bootloader. There was an error message. Then I fastboot flashing unlock on the console. Then the bootloader is unlocked. No idea why this worked.
Maybe this will help someone who encountered the same problem.
Wanting to root the device via magisk, I tried first to unlock the bootloader of my phone but apparently failed.
I started by activating the developer mode, set oem unlocking developer option in the settings then tried adb reboot bootloader : no success, the phone simply rebooted. A fastboot oem unlock just hung out waiting for a device.
I can go into download mode or recovery mode if that may help...
Any idea how to unlock this bootloader ? How can i check it is effectively unlocked ?
Thanks in advance for any help
It's well known that SAMSUNG mobiles don't have the Fastboot feature: there it's the Download mode.
FYI:
Power off your device. Press Volume Up + Volume Down and plug in your device to a PC to boot into download mode
When you enter download mode, Long press Volume Up button to unlock the bootloader.
ok well, let's forget about fastboot command then.
I'll answer myself on the original question, to unlock the bootloader:
switch off the phone
press volume up and volume down key
plugin a usb cable
choose "device unlock" with a long press volume up
after released the key up, choose "unlock" with volume up again
Now I'm looking to enter the download mode which I can't reach anymore. Any idea xXx yYy ?
Answer myself again
Apply the 3 first steps of my previous answer, you'll be in the same unlock screen as before but the first option will be "Continue". Choose it with volume up and you will end up in download mode !
Now I'll try rooting with magisk...
Rooting with magisk 25.2 done by a classical patching of AP from november release: AP_G736BXXU1BVK2_G736BXXU1BVK2_MQB58744363_REV00
It appears that this is the only thread on the entire forum for this phone?
Having just bought one for the removable battery and the dual SIM, I discovered that samsung in their infinite wisdom disabled the multiple users feature in their oneUI ROM, which really sucks because that was part of the reason I wanted the phone, to segregate certain apps into their own user account.
This all made me realize Root + custom ROM is probably the only way I will ever get that basic functionality returned.
So here I see that rooting is doable, but there appears to be zero results for un-samsung'd ROMs.
Which market is G736B? I was looking at ordering but I am in the US and the Samsung site is giving me the SM-G736UZKEXAA. Would the classical patching work on that?
The G736B model is sparsely distributed in EU, Asia, Africa and Oceania (see here). Your G736W US model is also based on Snapdragon 778G, it is probably the same phone with a few subtleties concerning 5G support (if any, can't find out) and software bloatware. I'd be surprised the above patching doesn't work but ... it's only a guess !
