Chinese tablet: Help with bootloop - Android Q&A, Help & Troubleshooting

Hello friends, I ordered a really nice looking Android tablet from AliExpress, and in the process of attempting to get to the goal or rooting it I have apparently broken it, I have searched through forum after forum for clues on how I can go about fixing it, but I have come here to ask for support from the greatest community on the internet, you all. Here are the details:
For reference, here is the link to the tablet I purchased:
https://www.aliexpress.com/item/10-...912.html?spm=a2g0s.9042311.0.0.78df4c4dxi2Tgy
I am able to get to the "Factory Mode" screen, choosing "Version", the following info is shown:
BB Chip: MT6580
MS Board: KT107
Build Time:
2018 03 06
11:43:04 CST
Kernel Ver.:
3. 10. 72+ ([email protected]jty) (gcc version4 4.8 (GCC) #4 SMP PREEMPT Tue Mar 6 11:45:14 CST 2018
Android Ver.: 7.0
SW Ver.: KT107_L1_20160428
Custom Build Verno.: unknown
IMEI1: unknown
IMEI2: unknown
Modem Ver.: unknown
Bar code: unknown
How did I get to the point where I am now? I enabled OEM unlocking in developer options, then enabled USB debugging, then I rebooted into fastboot mode. After that I ran the command "fastboot oem unlock", I was then prompted to tell it yes or no, I said yes, and it then brought me back into fastboot mode. I rebooted it, expecting it to perform a factory reset, and ever since then it just hangs on the boot screen indefinitely. The screen is animated (the normal boot sequence) but it never gets farther. I'm able to get into "Factory Mode" as well as the screen prompting me to choose "Normal Boot", "Recovery", or "Fastboot".
I have not been able to find a working recovery (downloading the img then trying "fastboot boot xyz.img", it tries to boot but then says "unknown command" before failing). Even if I were able to load up a recovery like TWRP I don't know how exactly I'd go about trying to fix my situation.
For clarification I haven't flashed anything, I've only tried to unlock the bootloader. I then tried to relock the bootloader, same result.
Any help would be appreciated! I would hate to think I spent that money and broke my tablet without even having it for a whole week! Thanks again in advance!!

Hi there,
This will be impossible the only solution I could think of is contacting the manufacturer and asking for the stock ROM.
However all is not lost you can try and search your ROM on this website.
www.needrom.com
I'm not really sure but you can try to boot up a custom recovery using adb and then reset the whole tablet it might work
ONLY BOOT THE RECOVERY AND DONT INSTALL THE RECOVERY AS IT MIGHT NOT BE COMPATIBLE.
yet I will research more about this tablet to help you out in any way.

Resolution
Thank you for the resource for roms (NeedROM). Though I didn't find a recovery or custom ROM for my device I did try several fastboot commands, and turns out running "fastboot format cache" and "fastboot format userdata" made the device bootable. Handy info to have if ever you are in such a situation!

Updates?
I think I've just purchased the exact same device and was wondering if you made any progress whatsoever? I'm in dire need to overclock it for that extra horsepower among other things. I've scoured high and low across many forums and have had no joy in finding anyone's success story. It's killing me that I spent £60 on the thing for only 1 reason and it can't even do what I need ??

I managed to build a working twrp recovery for this device. If anyone is interested then I will post it up somewhere. Would be really nice if someone had a working open OS, lineage etc for this. If anyone gets one I would be real interested. I tried a few things Hexagon, Infinix could not get them to work even though I followed the 'guides'. Two fruitless days wasted on this and the frustration shows now. Anyway enough griping from me, point is : 1.I got twrp on this device if anyone wants + 2.would love a lineage os(or equivalent) ROM.

I did exactly the same, I tried to flash many ROMs but none works, I don't have a premium needrom account to download this https: // ww w.needrom.com/download/jty-kt107/[/url] which is the Rom that I need to try and I think which is the tablet
Could you solve somehow? Or do you have a needrom account to download this ROM and try it? I would thank you and thank the other members of the group if they could help me, I will wait for a favorable response, happy day.

I could use the stock ROM/firmware too. It would be greatly appreciated if you could make it available, or direct me to where it could be found/downloaded.
