Firstly, the power button has gone faulty on my Nexus S and I am due to send it back to Samsung for repairs, so I want to get it back to factory image 4.0.4 IMM76D using the Google image and to relock the bootloader. However, when I reboot into fastboot all the keys stop working and I presume it has stopped responding and the only way to reboot is to do a battery pull. Just wondering if anyone has had this experience before and knows a solution.
By keys you mean volume and power right?
Does a computer recognize it with fastboot. Example . Fastboot devices / fastboot reboot etc?

Volume and power keys don't work while in fastboot and it isn't recognised by that. And when it powers on regularly it say No boot or recovery img. Nope, doesn't get recognised by PC and just says No devices found...
Did it work before in the same system?
Only other thing I could think of to try is download mode/Odin
It was working fine that day. I even flashed CWM on it after trying TWRP. But then suddenly the power button broke, and when I used the key combo to get into fastboot mode using the plug in to charger method it loaded fastboot and just wouldn't respond
So after having my phone successfully rooted with Magisk, I tried to port a twrp.img, obviously unsucessfully. I flashed it to the recovery partition with fastboot... and now the phone is stuck in a bootlop.
Can't power it off, and the method I usedpreviously to enter fastboot mode (power + volume up) doesn't seem to do anything now.
Is this a brick?

So I managed to unbrick my phone.
I needed to use Mediatek's SP_flash_tool ( https://forum.xda-developers.com/t/...-sp_flash_tool_linux-mtk-mediatek-soc.3160802 ) to flash a working recovery (e.g., the stock one) and everything was fine afterward.

Hi, could you be so kind to elaborate on how you rooted this phone? I am stuck between sketchy apps and incomplete help guides.
All I got done is to unlock bootloader.
Thanks!
Using Magisk, patching the stock boot.img with Magisk Manager and flashing it.
hello i m to unlock oem from adb and reboot tablet but it won't start only restart and go to boot mode volum down not working to choose fastboot
If english isn't your main language then use google translate and I'll try my best to understand.
Anyway, does adb recognize your device? Does adb devices returns devices attached and a serial number?
If so then try adb reboot bootloader
Or try manually booting with volume buttons, usually it's (Volume Up + Power) combination, on some devices it's (Volume Up + Volume Down + Power) combination.
You have to enable USB debugging and oem unlock in settings for any of this to work.
After successful booting to fastboot. Use fastboot oem unlock for older devices or fastboot flashing unlock for newer devices.
Then use fastboot reboot after successful unlocking. Note: Most devices use prompt to confirm bootloader unlocking which in turn requires the user to select "yes" with volume buttons.
If your device doesn't boot to bootloader and you have oem unlock and usb debugging on and tried all of the above. Then most likely your device bootloader cannot be unlocked, which explains why you can't find your device in XDA forums.
I did all of the above, but after unlocking oem, this is what the picture became
volumn down not working
I'm not following here, what exactly happened? Did you unlock the bootloader?
yes I unlocked the bootloader but after fastboot reboot it does not turn on it reboots only as shown in the video
Try booting into fastboot again and using flashing unlock_critical
I can not enter the fastboot mod because it does not work for me volumn down
Is your device detected on your PC? Try adb reboot bootloader
after unlocking oem, the tablet does not turn on and does not see the pc
Try connecting the device to your PC while pressing volume button to boot to bootloader. If it still doesn't boot then you can only fix the volume button.
Can you tell me what's your device model?
my model is x101 china model tablet .
boot only working volumn up
I can not choose boot mode
I never saw a bootloop after unlocking bootloader before. Maybe you modified your device in anyway before doing this? Like one click root apps or anything whatsoever?
If you can get volume down to work then you should be fine. Also try power button too pressing it should have the same effect as volume down.
I haven't modified anything. only the power button does not work only the volume up and the volume down is not pressed Please help me how to recovery system

Is your device battery removable? If so, remove it and wait 5 minuets and connect your device to your PC while pressing volume button to boot into bootloader.
If not then completely discharge your phone and wait for 24 hours. and then try connecting it to your PC while pressing volume button to boot into bootloader.

I discharged it but still nothing fixed
Hence the reason not buy cheap Chinese products. You can only take it to a service center to fix the volume down button.

Hey,I want to root my LG V50 (LM-V500N) but my phone can't go to bootloader and Recovery.When i access the above 3 modes it just reboots.Someone pls help me.Thank you so much.
I have the same issue with bootloader and recovery. for edl, sometimes i need to boot phone to download mode (hold vol up) and then hold vol down and power, and as soon as screen turns off, i spam volume up while continuing to hold the other two buttons. it can take a couple tries sometimes but you know it works when you hear the connected sound on the computer
hey, try to boot into qfil, flash engineering abl onto abl partition, and then reboot the phone and hold down volume down to boot into recovery. it should give you access to bootloader and you can get to recovery from there. i dont even know if its possible to break edl, i think if you do the trick where you first boot to download and then try to go boot to edl it could work.
So I succesfully flashed the rom using sp flash tool and now I Think my phone is stuck in edl mode.Can someone say me how to exit?
Just long press the power button or with volume buttons combinations
