my phone doesnt't boot using power button. it only boots when it's conected to the computer (the green led comes, and after a coulpe of minutes it boots) but doesn't pass the M logo (which by the way is teared beacuse of the ROM (epinter 4.2) <--- that is normal) i try to enter fastboot mode by hitting the vol down (or up) button when booting but it can't enter fastboot mode.
i've searched this problem but none seem to have it my way (i mean no boot, no fastboot). any help would be apreciated.
Code:
adb shell toolbox reboot bootloader

I got a tablet device (Omega OT107) I've rooted it using
Code:
ro.kernel.qemu
method.
Next I'm triying to flash Custom Recovery and my problems started here.
What I've tried:
1.
Code:
flash_image recovery
- no success process of flashing never ends
2. Install bootmenu to /data/bootmenu
3. Installed 2 different 2Init's
None of this worked or even had an impact on how device works (it always boots in android correctly).
I've tried to boot it to fastboot mode to flash recovery from there but there is a problem that I have.
Volume(up or down) + Power buttons starts device to Android not to bootloader (I've read you need to remove and reinsert battery to make it work, but device has a build in batery and needs to be taken apart to remove it so I did not tryed it)
Code:
adb reboot bootloader
- boots to what I think is a bootloader (screen is black(no light is comming out of it)) when connected to Windows PC it is seen as Android Bootloader Interface (Android-SDK driver).
Code:
fastboot devices
does not discover any devices, clicking volume or power button does nothing.
Code:
adb reboot recovery
- boots devices it what seems to be useless recovery mode. At start there is a standing android dude with fireball on his chest, and imidietly changes to a lying position with his chest oppened and an exclamation mark comming out of it (I've red it is ok and I need to press Volume(down/up) + Power buttons to open recovery menu but it does not happen).
My question is:
Is it normal to some devices bootloader to look like mine? How to make it discoverable to fastboot?
I had this issue and I fixed with "press all the buttons!" and suddenly I sow recovery menu...to factory reset. if it doesn't work repeat with rebooting with pin
Does someone knows a way how to hard reset this thing?? ^^
about firmware
Any idea where find the firmware for this tablet?
Mine is now freeze on recovery logo
hard reset OT107
1.Turn off our tablet.
2 We press the MENU button at the same time + POWER HOUSE click and hold
3.Wait until the Android image.
4.Then VOL + button and the POWER and appears to us to Recovery Mode
5.Navigation is Vol-i + and confirmed by pressing POWER.
I accidently wipe system and stuck on boot! :crying:
How do I access to recovery? I want to restore the system. Is there anyone knows how to boot into recovery by using something else?
Hold down power for 10 + seconds until phone is fully off, then try the hardware button press again
( volume down button whilst powering on.)
Usually the hardware buttons will override and stop it trying to boot
If not will adb recognise it if you plug it into PC?
plug it in and in cmd type 'adb devices'
if recognises try 'adb reboot recovery' in the cmd prompt
I tried to enter recovery to unlock the bootloader but all i get is a blank screen with the LED shining blue.
I tried it through adb ( adb reboot bootloader) and the button combination (vol. up + plug in cable).
Also tried adb reboot recovery, but it only reboots back into the system and vol. down + plugging in cable results in the same blank screen but with a green LED.
Please help!
No recent Sony device ships with a recovery.
In order to unlock your device follow the instructions in https://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Next time before opening a new thread read the forum. Chances are your questions are already asked by others. Good luck unlocking, flashing and freeing your phone.

Hi,
I tried to flash lineageos 16 on my bkl09 emui9.
It was working but it was impossible to install app by play store... I tried many times to re-flash lineage img.
I'm actually blocked on TWRP. But it doesn't launch. When i start my phone, it boots on twrp, and the phone stays on the twrp boot screen but doesn't launch.
I can't turn the phone into fastboot mod by pressing vol- and power . It just restarts and reboot recovery twrp and block on boot screen twrp without launching...
I plug my phone on my computer, it reconized as adb devices but when I try to turn into fastboot mode by adb, nothing happen...
I hope there's a solution !
(and sorry for my english ... :/
power off the phone, put USB port in phone, press volume down key, now connect USB port to PC with volume down key press. it should boot to fastboot.

hi. Please, help, i cant reboot to fsstboot. If i do this from app or from adb my phone just reboots twice. I can boot into recovery and into download mode
Don't reboot into fastboot, boot into fastboot.
1st hold the up and down and power to start up so that it shows more than that "...is now booting". Then power off and press "down" and "power" with USB plugged to enter fastbboot. In fastbbot, flash the userdata.img and the cache.img (This cleans data and cache totally) from Huawei's updates, then you will be able to get into TWRP without being stucked.
Hello,
my phone is unlocked (did this a year ago through miflash_unlock tool when fastboot still worked) but after flashing latest stable global firmware and latest TWRP I cannot enter fastboot anymore.
- When I hold volume down and power key for a few seconds the phone powers on but the screen stays black. (The screen is clearly on but it's just showing black.) If I keep holding both keys it just powers off and on again, again to a black screen.
- In TWRP if I choose to reboot to bootloader I get the same black screen.
- If I'm booted into the ROM, USB debugging enabled on phone, connect to my PC with adb and run "adb reboot fastboot" the phone boots directly into the ROM.
- If I run "adb reboot bootloader" instead it boots into the black screen.
What is going on?
