When the phone was rebooted, the phone began to constantly optimize. Phone without Root, the bootloader did not open. I wired with the wipes through Flashtool, everything was done without errors, but it did not help. Then I decided to restore via Sony PC Companion, too, the process was completed without errors, but the phone is again reloaded on the logo. When connected to the usb port, the phone immediately switches to Flashmode, then in a couple of minutes it reboots and so on in a circle. In Fastboot mode, when the key is held, it enters, in this mode it does not reboot while it is connected to the usb port. If I connect the charger, the red LED lights up and the phone tries to boot, but on the logo again bootloop. Because of this, the yellow LED does not light up and the battery does not charge. What do you advise?

Greetings!
The tab is DANY GENIUS TAB G4.
The tab was rooted with KingRoot android app and bootloader was accessed. But it got stuck in bootloader. My assumption is that I may have selected fastboot mode by mistake. But nothing happened after it, just stuck on the same bootloader screen. The battery died and tab didn't boot again in any way, nor did it showed to be charging.
One of the solutions related to charging it for a while worked to some extent as it finally showed charging screen. But upon booting up, only the LCD turned on with nothing but dark screen (no logo, nothing) - and that too only till the power button was held down. However, the bootloader was accessible. But in bootloader, nothing seemed to work. There are three options in the bootloader:
- System Recovery
- Fastboot mode
- Reboot
I tried entering system recovery but when I selected it, the tab would turn off immediately. I then tried selecting "Reboot", the tab again turned off immediately with no screen/logo or whatsoever. I did not try connecting it to PC at this point.
Could it be that ROM has been damaged? I already found and downloaded its drivers and ROM on PC. The tab hasn't booted since last time nor gets detected by PC, so I'm once again leaving its battery to be depleted for hours and try charging again. I plan to reinstall the ROM on it, if it does gets detected by PC.
My question is,
1. Is there anything else I should try first?
2. Any way to make PC detect it if it doesn't gets detected next time I boot into bootloader/flash mode?
3. Why isn't bootloader working?
Any help would be greatly appreciated!
Here's the list of things that I tried before charging it worked:
1. Hold power button for 1 minute while on charging, as well as without charging.
2. Hold power + volume up (bootloadder combination) for 60 seconds. While on charging + without charging.
3. Connected to computer. Repeated step 2 and 1 along with it.
4. Flash a bright light on its light sensor while holding power button. Also try volume down or up button along with it. As well as on charging + without charging.
5. The charging one was actually tried before, but it only worked when I left it for about 10+ hours without charging and then to charge till the charging screen showed up on its own.
More Information:
The tab was first Factory Reset from the settings, then rooted with the KingRoot 'android app' (not PC). But since there was no SuperSU or related app automatically installed, SuperSU was installed separately. Upon installing SuperSU, a messsage appeared saying something like,"Binary not updated".
The bootloader was accessed to wipe cache partition. It took sometime so it was left alone. It rebooted normally, so assuming it was successful, it was booted into bootloader again.
It was at this point that bootloader got stuck, and I assume that it may have to do with selecting fastboot mode.
Resolved!
It's the third day, and the tab was once again left for its battery to be depleted for around 15 hours and then plugged in to charge for about an hour. It once again finally showed charging screen, but screen would turn on with no logo or anything else (same as before). Thou, before charging screen showed up, tab was removed from charging for a little while this time.
The tab was left to charge for about half an hour before charging screen showed up and then booted again. This time it booted normally and was working fine!
For those who may encounter the same problem, keep trying for at least a week before finally giving up. Here's a few suggestion that some people gave me to try:

3. Play dumb. If it's on warranty, do a warranty claim. They won't be able to tell it's rooted since it doesn't boot up and nothing works.

After a busy day, My phone Charged down to 1% I have put on charging and after 5% i pulled the charger out. Put an alarm and slept. After waking up in the morning I saw it was Off, I tried to Charge but red light didn't respond. I tried to switch on, the screen blinked black light for 2 seconds. Later I have tried pressing Home+Vol Up+ Vol Down, I have tried Recovery mode and Factory Mode it turned off after blinking for 2 seconds. Thats it and dead. Now no response from phone even I charged the battery from another phone and put in this. There is no screen blinking from then Onwards
I tried :
Flashing with SP Flash but when connected to PC It is not detected as Mediatek Driver 'USB Device Not Recognized' In Device Manager it shows 'Unknown USB Device' Port Reset Failed. Re installed Mediatek drivers and tried VCOM too. nothing worked.
Last year I have updated to Lollipop officially connecting it to wifi and selecting 'Software Update' in Settings. From then USB is not detected whenever I connect PC, It only charges the phone there is no option of USB Mass Storage. So I have never turned on USB Debugging option.
I never:
Tried to Root, Flash or Change ROM and any Software related works.
Please help me in this issue. How to Recover It. How to Flash it and Install any Lolllipop firmware without losing Phone Storage Data (If possible).

If you did not do any software related work, you bootloader must be locked. Which means you cannot flash any ROM by yourself. The only thing you can do right now is to hand it over to the service center. There is absolutely no other way.
But such a case is absolutely impossible if you are not rooted. If it is still under warranty, exchange the phone. Or your phone must have been refurbished at some point of time.
my problem
Is there any other way that can we do anything by ourselves rather than giving it to service center
so yesterday i was playing on the phone and suddenly the whole phone freezed and a strange cracking sound come from dthe speakers, i turned it of by pressing long the power button and it never turned on again.(blugged on a charger and try on pc if its recognice any qualcomn driver but nothin)
in the morning i tried again to charg but noting and i give a try on pc and suddenly a red led is started blinking after 3 hour it booted up and started to charge by 10%hour. (pc cannot recognize the phone while booted up)
so i try to uninstall every xposed and magisk mods
it turned into a bootloop (with stock recovery and unlocked bootloader) and nothing can recognize it in fastboot .
Any advice??
I recently updated Magisk from 16.0 to 17.1. The installer asked to reboot after finishing up. After rebooting, however, the phone gets stuck on boot animation. I've tried to let it run all night and I've tried charging/discharging a few times. The bootloader is still unlocked (the opened lock icon shows up under the Google logo on boot). I can't get into recovery/fastboot mode: Holding power+volume down turns on the phone but gives a black screen with backlight on. My computers also don't recognize the phone. I haven't found any similar issues here while searching so I am at a loss on how to fix it.
Possibly related: Charging the phone has been weird for a few months: the charging LED indicator only turns on when the phone screen was on. It seemed to charge slower compared to previously and the OS doesn't recognize that the phone is charging.
With the phone off, hold the volume down button and connect the phone to your computer. This may force the phone into fastboot mode.
Thanks for the advice! Although that didn't immediately work (it still booted to a black screen w/ backlight on), I tried one or two more times to boot holding down volume down + power with the phone unplugged. I got lucky somehow and it finally booted to Fastboot. From there, still neither my MacBook nor my Windows computer recognized my phone (nothing in device manager). I booted to TWRP, and saw that Magisk had .zip's of previous versions stored in /sdcard/MagiskManager. I flashed the last working version, 16.0, wiped Cache and Dalvik, rebooted and finally got through boot animation.
Time to backup!
Hi Everyone,
Recently I have unlocked the bootloader and flashed twrp after upgrading to OOS 13 after that I have not able to access any storage(including OTG) so I had changed the format of disk. Now its stuck is bootloader and show qualcomm icon when starting and just keep on trying to boot(stuck at logo not a loop or anything). I am not able to get into the EDL mode or fastboot for that matter any suggestions
Video is uploaded to show the icon it continues to normal oneplus logo boot and stays there
can you hold vol - and power with it unplugged until the screen goes black, then fast as lightning hold both volumes and plug it in? I used to have this device and I'm trying to remember what I did to get out of that.
I had always waited till the phone got discharged and then tried again EDL used to work when I had the flashboot but now it not a possibility it resumes into the unlocked bootloader alert (sometimes press power to pause or continue to boot) and then logo not matter which combo of the buttons I tried
If nothing works you can always take the back off and unplug the battery.
Doesn't discharging the phone will also do the same or are you suggesting me to go into edl by removing battery cover and plugging in like the old mediatek recovery method
Have you tried unplugging the device, using volume up and power to fully shut off the device, then wait a second, and switch to volume up and down, while plugging in? Important to keep it unplugged until going into EDL.
It's already fully shutoff when I discharge it to recover from the boot animation. The keys combo don't work at only power button work to continue or pause boot
