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 tried installing TWRP after turning off the bootloader. I clicked on Recovery in the Fastboot and now it's stuck in "Entering Recovery...". The phone restarts with that screen every few seconds. Holding power+volume down doesn't do anything (unless I'm not timing it right). What can I do?

I know this is late, but I just went through the same damn thing. Twrp 3.1.0.0 forces a recovery loop, install 3.0.0.2 instead.
As soon as you see the "entering recovery" screen, hold volume up and power until your phone restarts. (If it goes back to recovery, wait until it loops and do it again) as soon as your screen goes black from the hard restart, hold volume down and power to boot into your phone regularly.
After your phone boots, use the twrp app to install the previous version of twrp. (Like I said, avoid 3.1.0.0 like the plague. I've already brought this issue up with the recovery handler, hopefully it gets resolved.)

There is an alternative that I've found very useful. And have tested it out several times while attempting to in-OS factory reset. If you're stuck on the 'loading recovery' screen and it continuously reboots, perform the following steps.
1. Press the Power button and Volume Up button at the same time, and keep held for 10 seconds until the screen has gone off.
2. Once you know it's gone off, quickly switch from Volume Up to Volume Down, keep held down.
-This should let you be able to enter into the Bootloader menu. From there, you will require Minimal ADB/Fastboot installed on your computer. Opening up an administrative command prompt within the ADB folder by pressing down Shift and right clicking on the window of the folder(or in my case since Windows 10's new update no longer opens that up, instead opens PowerShell, copy and past cmd.exe from System into that folder (DO NOT CUT AND PASTE, OR DRAG AND DROP)), type in the following.
fastboot devices
-If your device shows up in this list, then you're good to go. Head over to the TWRP website and find your HTC 610 TWRP version, or do as I do and just select 2.8.4.0 and download it.
-Rename the downloaded file as "twrp.img" and drag it into the ADB/Fastboot folder in which you loaded up the cmd prompt from before.
-Next, back to the command prompt you loaded earlier (if you haven't closed it by now) and type in the following:
fastboot flash recovery twrp.img
-This should copy the file over to your device. After this is completed, go ahead and reboot or boot into recovery. This last option I've not attempted immediately after flashing TWRP back to the main system, but that's because I'm working with an older version of CW12.

Just holding volume up and power worked for me.After the splash screen appears continue holding volume up but let go of power and it will boot I to go.e screen as usual.I then just used the twrp app and flashed 3.0.2.0
hey, i've got a problem.
i'm running on Oreo 20r and installed Magisk using TWRP.
after rebooting, my device stucks in a bootloop.
is there any solution for my problem?
flashed magisk 17?
yes...
okay, actually I am currently stucked with the same issue too.
But I just got back my TWRP by doing following :
1) Boot into download mode (https://www.youtube.com/watch?v=_mycJDiFUPk)
2) Still in download mode, press and hold "vol down + power" (this time USB cable is still connected to PC and phone), it will reboot the phone, hold both button till you get in fastboot mode
3) once in fastboot mode, flash back TWRP as per unlocking guide
Now I am still in TWRP, hesitating what to do next. lol
Hope it helps a bit
it's not possible for me.
my device reacts to nothing... no keys, no recovery, no download mode
bootlooping like no tomorrow
maybe you can install KDZ-file using LGUP
or try to flash ZIP-file

I just clean flashed back Boombox 1.3 with magisk 16.0, so far booting up good.
I think you need to try again.
The download mode is a bit tricky, need to very fast hold long power button till off, once off, hold the vol up and connect the USB cable to PC. it should trigger the download mode
The bootloop that you have now, is just "LG V30 ThinQ" and the "unlocked bootloader" msg right? same as me I think

okay, let me try describe my steps in details :
1) Phone is bootlooping, USB cable is connected to Phone, NOT to PC
2) Hold down power button only till the screen becomes "black"
3) Once "black", quickly hold the "vol UP" and connect the USB cable to the PC
4) Now it should show the "download mode"
5) Without removing the USB cable, hold "power + vol DOWN"
6) Once screen becomes "black", release the "power" button, hold the "vol DOWN"
7) Until you see the "fastboot mode"
8) Now you can flash TWRP back using fastboot command from the PC
9) Boot back to TWRP
p/s : yes, the phone cannot be turned off, for long time, but it can be for a very short time. Need to use that short time to trigger all the keys
I have the same problem after flashing Magisk 17. I am in a bootloop between LG black start and root/unlocked bootloader warning screen.
I followed your steps 1-7 in a command line screen (as administrator) and it works but it seems that recovery flash is not working because the command line screen show me a very short time in the recovery flashing work (see attached image).
"fastboot reboot" returns me to the bootloop.
"Power Off" and "Restart" options in the phone returns to me to the bootloop again.
If I unplug the USB cable in the fastboot screen, the phone goes to the splash black screen and does nothing.
WTF!!! it's working.
i tried it one more time like you described it.
think i did it too slow before. booted into TWRP and the rest will be no problem (i hope so).
thank you sooo much!

use this description to enter download mode and flash TWRP using fastboot.
but after you flashed TWRP, you have to boot into TWRP via fastboot using this command fastboot boot TWRP-3.2.1-joan-v0.1.img
1) Phone is bootlooping, USB cable is connected to Phone, NOT to PC
2) Hold down power button only till the screen becomes "black"
3) Once "black", quickly hold the "vol UP" and connect the USB cable to the PC

how did you reflash Magisk 16 after?
@ChazzMatt HAve you looked at this? Some of are having issues after Magisk updated the Magisk app and then lost root...I guess we shouldnt have flashed 17, but when I try and reflash 16 I get the "updater process error" does that mean my only option is to format SD again, or do I have to start from scratch?

No, see the last few posts of WTF thread. You just have to uninstall 16 first.

I am stuck with the same kinda issue. By mistake restarted the Phone after wiping the phone for a fresh rom install. now i can see only the LG boot logo. There is no way to power off the phone. Pressed the power button alone for couple of minute but no use. Tried pressing the Vol Down and power to restart. I get a 1 sec window when the phone is off between the restarts but your method does not work in that short time. Is there a way to power off the phone ?
basically there is no Rom on it and does not detect on the PC when plugged in
Please help if you know anything

Try going to TWRP
1. hold vol down + power till it off
2. Once it shows the first on screen, release the power button and press back the power button (vol down hold)
3. A menu for factory reset will be shown, agree to it 2 times
4. Then it will boot to TWRP ( no data will be deleted )

Hi. I have an LG Stylo 3 Plus (32GB) on Telus, with a locked bootloader and no root.
I am trying to enter recovery mode to clear all the caches, however doing
Code:
adb reboot recovery
just takes me to the screen that says "no command" and has the android on its back.
What key combination do I use to enter recovery? I have tried volume down when plugging in a USB cable, however that just brought up fastboot for unlocking the bootloader.
after you flash a new recovery, take the battery off, an right away press the volume down + power button until you see logo. When you see the logo, just take your finger off the power button and press it again
I accidently flashed the lineage 16 recovery instead of lineage 17.1 recovery. I tried to install the 17.1 update through updater but my phone stuck into recovery mode. Neither I can boot into bootloader nor to android. I can''t flash anything. Power + volume down and connect the cable also not working to go into bootloader. Even bootloader option within the recovery also brings me back to recovery mode. ...adb devices command is also showing "device offline". Any help will be appreciated.
you should start from the beginning
is your bootloader still unlocked?

I can't go into fastboot mode. Is there any other way to check it?
Thank you @stukka2006 for replying me. I guess I saved my phone. So here what I did-
1. Extracted the stock firmware (Luckily I had one but can be found in the forum) and copied the dload folder to sdcard (as I was not able to access internal storage). (@stukka2006 your hint to start from the beginning)
2. Power off the phone and pressed Both volume buttons + power button simultaneously. After the vibration I left the power button while still holding both vol buttons till software update screen appears. But software update failed. So I just touched the reboot now option. The phone rebooted to fastboot mode.
3. I installed TWRP but was not able to reboot to recovery through commands and system reboot command brings me back to fastboot mode. So I again power off the device with cable connected and pressed both vol buttons. This time phone showed recovery screen (Should have worked with normal button shortcuts also, I guess) and I flashed the rom and rebooted normally.
Everything is working fine now except that I lost the data.
Happy you got all clear my friend !!!
