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.
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?

Hi there
I beg your help, I wanted to install the aicp pie version on my tablet spg512 model but I don't understand why, I can't boot on the recovery mode, the device always do a normal start.
I've tried to use the buttons combinaison:
Power + sound - : nothing
Power + sound + & usb cable: download mode (blue light)
Power + sound - &+ : nothing
I've correctly flashed twrp with fastboot as described in some tutos, also tried with older twrp versions and the bootloader has been unlocked by sony serial code procedure.
When I ask fastboot oem unlock, the system told me that the device is already rooted but when I ask suchecker/flashify/twrp app told me that the device is not rooted
The device is recognazised by fastboot and adb. What I'm doing wrong to get access to the recovery mode?
thanks for yours helps
edit: in console fastboot reboot recovery : fastboot: usage: unknown reboot target recovery
I'm not sure about your experience, but for me when I reboot the tablet it shows the Sony logo for a few seconds and then the notification LED turns on in a green color. If I then hold the volume down button during the time that green LED is lit it will change to purple which indicates it's booting into twrp recovery.
I also had the issue that TWRP didn't start up on my tablet, no LED lights, no key-combinations. I described it here: https://forum.xda-developers.com/showpost.php?p=83555173&postcount=29 . Maybe my solution could help you?
Hi!
M4 Aqua, E2303
Brief history, what I did before:
- On a full stock OS, first, I unlocked bootloader with fastboot oem unlock, which went through nicely.
- After that, I followed this thread to install custom recovery (twrp). Went through nicely (fastboot flash recovery recovery.img and fastboot flash boot boot.img).
- I was able to boot into recovery (twrp), and with the Install function, selecting Conceptify .zip it installed, rebooted.
- On the boot, the Conceptify gear logo was stuck spinning for a very long time. Then I just tried going into TWRP again to install Conceptify again, maybe for the second try it installs without the boot issue.
After this, I was no longer able to enter twrp recovery again. Okay, tried to flash the .img's again (boot and recovery), maybe I can at least get into TWRP recovery again, but no luck, despite both flash commands going through (both sending, writing were OKAY), without errors.
Current symptoms at this point:
- I still can get into fastboot (vol Up + usb plug in; LED red, then blue), and my PC can recognize the phone being in fastboot correctly, with serial number (in fastboot devices). It can still perform the flash/erase commands, but whenever I try fastboot reboot or fastboot reboot-bootloader, it doesn't reboot the phone. At this point, fastboot devices gives back a device in fastboot mode, but with a lot of question marks (?) instead of the serial number. On unplugging it, LED stays blue, like it is frozen or somthing. I kill the phone off with the power cutoff switch (next to microsd).
- holding just Power to turn on phone: Sony logo on the white background and is stuck. After a while I kill off with power cutoff.
- holding Power + vol Up, it vibrates once every 2 seconds or so. Nothing on screen, when I stop holding the buttons, stop vibrating. It however stays in a weird state, cause I can't get into fastboot for example (vol down + usb plug in; like I can do when it was powered off completely). I kill off with power cutoff.
- holding Power + vol Down: Sony logo on the white bkg, and stuck. After a while I kill off with power cutoff.
- tried the all-button hold: Power + vol Down + vol Up for 30 seconds, it was just vibrating every 2-seconds.
- flashmode with Flashtool: I downloaded a stock .ftf, loaded into FlashTool, but upon asking to connect the phone while holding vol Down, it can't detect it. The phone however lights red, then green on the LED light. Tried with both a new Flashtool (0.9.32.0, and a recommended older one as well: 0.9.18.6).
Is there something else I could try to get a working TWRP recovery again, and be able to boot into it?
Thanks for your help!
My M4 (E2312) have pretty much the same symptoms: can not boot anything and just stuck on SONY logo, Flashtool does not recognize phone in flashmode (Vol -), just fastboot. And using fastboot to flash system, boot, recovery shows finished processes but phone does nothing new. And phone does not response well to USB, only after a reset then it updates the status.
I have Pexo ROM v3, custom TWRP, SkyMelon 9 I think,Rooted SuperSU and Magisk( has conflicts so when I boot some pop up says X app has stopped working. When I install some more apps to use it was ok, then the pop ups show up more and more and then it decides to boot loop to the stage we are now.
I have tried install 0.9.33 and 0.9.23.1( somehow only 0.9.23.1 can install 3 drivers), Xperia Companion, Emma, ggsetup 3.2.0.1, Driver SONY so0104 (so0113 ADB interface- status show it cannot start),
So either it is the drivers on computer, the computer USB ports, the phone's software or hardware defects lead to software that caused it.

Yes, I also tried installing conceptify but it doesnt work. At this point its better if you stick with the stock rom, remove as much bloatware as possible and consider it a phone because almost none of the ROMs here work stability wise, or they maybe stable but some features like display brightness or speakers dont work. So I recommend you install stock rom via flashtool and then unlock the bootloader via flashtool again and install twrp again. Also if possible try reinstalling the drivers for the phone in flashtool. Hope this works mate.

Unfortunately, I still can't make Flashtool recognize my M4 as booted in flashmode. Tried installing the drivers with \Flashtool\drivers\Flashtool-drivers.exe , but choosing the "Flashmode drivers" option, it failed during the install (I guess cause there wasnt a connected device that supports it), tried both with phone being connected in flashmode (volDown + plug-inUSB), and phone disconnected as well.

Can you try it on a Linux PC I guess?
I tried going through recovery to bootloader, but that does not put me in download mode. Any other tips except Adb. Just thinking about what I can do in a boot loop or brick except wipe.

If you're in recovery mode, you can use ADB to command a reboot to bootloader, which for most Samsung devices opens download mode as well - the screen is just black instead of green.
Getting into bootloader mode via the buttons depends on the device, but the universal method seems to be this:
Power device completely off, wait a minute or two
Hold both Volume + and - buttons, do NOT press Power
While holding Volume buttons, plug in USB cable connected to your PC
Device should start in download mode.
If you press Power, or connect the USB cable before holding the buttons, your device will just power on.
Going into bootloader does not put me into download. I ahead to use Adb reboot download and you can’t use Adb in stock recovery
