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.

If it's working then boot to the bootloader. And use fastboot flashing unlock_critical

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
Hi friends
I have problem like this:
My phone is turning on only to bootloader.
In bootloader works only vol + but it works like vol - button ( when i press + it goes down not up, power button don't working too)
2 times i don't know how I turned my phone in to safe mode.
In stucked bootloader my computer (win 7) don't recognise phone.
It is recognised in safe mode.
Now phone is in those bootloader.
What can I do? Is it brick forever?
Thanks

No ;/
In bootloader if you plug the cable it shows "Fastboot USB"
If not your HTC driver & ADB driver are broken. Re-install them.
Re-flash recovery.
Hi, it all started when I tried to install another ROM for my moto g xt1033. I accidentally deleted OS and storage.
Now it is struck at Warning bootloader unlocked screen. I can't even go into recovery mode.
I guess I hard bricked it.
Please help.
Thanks.
Have you tried to reboot into fastboot mode? Hold power button 5 seconds, after it reboots hold vol- key for some time and release it. If You booted into Flashboot mode you can install recovery or restore full system.

Yes I tried. It reboots with a small vibration to bootloader unlocked screen again.
It's not detected by fastboot when you connect it?

Hi !
I recently unlocked bootloader and installed TWRP on my device.
The problem is that when I try to load bootloader (adb reboot bootloader) my phone reboots in normal mode and I can't use fastboot.
Any idea to solve this problem ?

My phone is struck in bootloop after failing to root it.How do I factory reset it? What programs do I have to use and what comands do I give, preferibly linux ones?
You can try booting into the stock recovery: Hold down the volume DOWN button and power button until the SONY logo appears. When you see SONY, release the power button but hold the volume down button until the recovery menu appears. Then you can factory reset from that menu.
Or, make sure you have platform tools (adb) and the Sony USB drivers installed, and you can boot into recovery by:
Making sure the phone is off. Plug in a usb cable into your computer but NOT the phone yet. Then hold down the volume UP button while plugging in a usb cable and release the button when you see a blue light. The blue light indicates fastboot mode. Then, in a command prompt, make sure you have the device connected by entering:
fastboot devices
If your device is listed, then it's connected. If not, repeat the above steps. Then enter:
fastboot boot recovery
Your phone should then boot into recovery which will allow you to factory reset the phone.

; fastboot boot recovery
fastboot: error: cannot load 'recovery': No such file or directory
Then head on over to this thread: https://forum.xda-developers.com/t/...re-and-gsi-rom-flashing-without-twrp.4344373/ and go through step 7 with Xperia Companion
I tried that but it gives me the error:"Xperia COmpanion cannot update the device: the bootloader was unlocked"
ok I had to do `fastboot oem lock`
ok thanks I've fixed it!
OP reported the issue was fixed, thread locked to avoid further bumps.
