I have twrp partially working. The screen is displayed vertically, but touch responds as if it were laid out horizontally. Some of the partitions will mount, but not all.

Right now what's holding me back is simply getting logs out of the device. Adb won't start, and it can't write to anywhere I can retrieve the files.

I'll keep plugging away, but any hints would help a lot. I think I'm close to getting it working.

I can't wait to get a clean firmware on this device and finally have a usable tablet without constant Walmart ads and bloat
[Walmart Onn Tablets General] wedgimuss:
You can remove the bloatware apps via adb without root, there's 4 of them I believe.

I've gotten the latest Android 11 pixelexperience unofficial GSI image to flash and it runs great. Magisk is not working, neither is TWRP. I'm needing root to run a custom kernel for a specIfic use case I want for this tablet.

With patched Magisk from the stock boot image, the tablet just boots to fastboot.
[Walmart Onn Tablets General] tek3195:
The touch input is configured at build time with boardconfig.mk. I build mine in landscape for my tablets as it just looks better. There is an example of boardconfig.mk from my Tab S5e attached, look at bottom section and you will see the screen orientation, rotation and whether flipped on x or y axis. I'll have to look but it seems like I remember changing it in resource folder at one time in AIK. Post your /system/etc/twrp.fstab and we'll see what needs edited to get partitions to mount.

edit: thought I was attaching make file. added it but don't see it, will get it on here in a little bit.
[Walmart Onn Tablets General] tek3195:
I don't have a 2nd gen tablet but have looked at some of the .img and .bin files posted here. Don't know if needed but disable-verity may apply to more than just vbmeta as these tablets now have system_meta and vendor_meta partitions that are part of the boot phase. I don't have it front of me to remember what all I was looking at but those were part of the first round of partitions mounted and verified.

For deeper tinkering your tablet has MTK ULTRAFLASH capabilities according to lk.bin and lk2.bin, not much in the way of documentation on it. There was in fact no online documentation for it when I found it in the first gen tabs. It's not something one would want to play around with too much without documentation. It can write protected partitions with fastboot, like bootloader for instance would be bad to have corrupted as you would then not be able to write to it to fix it. Just something I found interesting with these tabs and thought I would add.
[Walmart Onn Tablets General] tek3195:
trying again outside of reply. still not working for me. boardconfig.mk is personal mediafire account, its clean with no bs attached. @rolenthedeep
[Walmart Onn Tablets General] onn.:
Did you have any luck with this? I'm in the same situation now, and am trying the SP Flash Tools, and for a split second, I saw a glimmer of hope, because I think I saw the device get recognized in device manager, but it had a popup that said what I downloaded at https://xdaforums.com/t/stock-stock-backups-images-otas.3998227/ (scatter file) had a version of MT8163 and mine was MT8168. The fact that I saw some movement in device manager makes me think I have a slim chance at possibly reviving the device after a bad boot.img flash.
[Walmart Onn Tablets General] tek3195:
Scroll up or back to post #330, that recovery.archive is not just recovery.img but full firmware minus scatter, but reference is made to scatter. Check it out.
[Walmart Onn Tablets General] onn.:
Thanks for the tip. After googling, I found https://xdaforums.com/t/help-needed-onn-8-gen-2-100011885-no-boot.4246787/post-84949449 which has the MT8168 scatter file I was looking for (as well as boot.img and recovery.img). Now I am researching which files to lump in one folder so that everything is in order for the SP Flash Tools. Thanks for the lead. One step closer to reviving this brick (hopefully).
[Walmart Onn Tablets General] tek3195:
Did you download that archive in #330 ? If so put them all in one folder, SPFT will pick the ones it wants according to scatter and leave the rest untouched. No flash specific folder just keep it all together, cleaner system all around that way.
[Walmart Onn Tablets General] onn.:
I did download the contents, and placed the MT8168 scatter file in that same folder. However, I got the error as seen in the pic. What I'm worried about it the MT8168 scatter file indicates a preloader file called "preloader_tb8168p1_bsp.bin" whereas the contents of the archive have a file called "preloader_mid8011_mq.bin". Apologies also if I should be posting a help thread or anything I already have somewhere else.
[Walmart Onn Tablets General] tek3195:
I wish I had one of these tabs so I could be up to date on versions and variants. I don't know if tb8168 is same as mid8011 with a name change or if totally different device. I'm guessing the bsp.bin is from board support package and don't know of mq.bin. If it turns out they are the same preloader renamed the scatter can be edited, but don't edit without knowing for sure. Wish I could be more help.
[Walmart Onn Tablets General] onn.:
This was my journey by the way. I only recall messing with boot.img so I don't know if that alone caused the brick, or if that caused other stuff to be erased/overwritten. Do you know off hand if you have to have every field filled in SPFT or if you can push individual files?
[Walmart Onn Tablets General] tek3195:
Sounds like you may have patched the wrong boot.img. Other stuff should not have been affected by flashing boot.img as long as you flashed it to boot partition and not somewhere else. Yes you can flash individual files in spft, just select the lines you want in spft gui. Are you on Linux or windoze ? I want to see how your device is detected. Even when it is not showing up for you there are ways to find it.
[Walmart Onn Tablets General] onn.:
Windows user and following https://devsjournal.com/how-to-unbrick-mediatek-device.html I fiddled around with the device yesterday and did some stuff like trying to push only a few files, but I ended up having to reinstall the VCOM drivers. The device previously would stay connected, as confirmed in device manager, if I held the power button down for a while, but after trying to just push the boot.img, vbmeta.img, and recovery.img, it seemed to make the device want to act funny to where if I hold the power button down while the device is connected to my PC, it pops up with a yellow exclamation point on the driver and then disconnects. However, at one point I was able to get a message from SPFT that said there was a target chip mismatch (I assume it had failed to try and flash anything then). This part I can't seem to reproduce yet. As far as the Android ADB driver, it has the yellow exclamation point too.
[Walmart Onn Tablets General] tek3195:
Continuing to hold power button while connected may lead to undesired results. There are different stages that it will go thru when you first connect it to PC, like preloader and brom. Holding power will try to reboot or restart the process. It's been a while since I've dealt with MTK but last one would be detected differently by button combination used when connecting usb. Something like vol- while connecting was preloader and vol+ while connecting was bootloader. Try searching for MTK button combinations, can't remember where I've seen it but there was a list of a lot more than vol- & vol+. Kinda thinking you may need to get someone to provide you a dump from a like device and use all matching files at one time, including preloader.
[Walmart Onn Tablets General] onn.:
I'm currently working on trying to find solutions to my current situation. I'll move to https://xdaforums.com/t/help-needed-onn-8-gen-2-100011885-no-boot.4246787/ where I'm putting my updates in the fix process. It's not listed there yet, but I have tried to select Upgrade option and put everything the other user said, but so far SPFT is giving me a hash mismatch error. I appreciate your help so far, and I will try to move to the more suitable thread there since I have the stock ROM files now (although scatter is slightly different).

[Walmart Onn Tablets General] Sloogle_Flugelmann:
For the 100011886, the gpt image is in a folder and there's a text file stating that it needs to be "cut." Is this file important? I flashed my tablet with this and the wifi and bluetooth don't work. "Bluetooth keeps stopping" constantly pops up and I notice the MAC, Bluetooth, and IP address in settings is "Unavailable"

Anyone have the firmware with Android 11 for this tablet?

EDIT: I got it to work finally. I tried twice already and it didn't work but I tried it once more and resetting Wifi, mobile & Bluetooth in reset options made it all work.

Try it with an Android device using WinZip or Xplore once it downloads you should be able to save it to your Google drive and download it onto your PC from there. Or transfer it using your preferred file manager and a USB connection.

I have a 100003562. I rooted it, then decided to put a gsi rom on it.

I got it to boot. But decided to push the remove telephony button in settings which bricked the tablet.

I have tried flashing every stock firmware I can find for this tablet, and I was able to get it to boot however, the touch input doesnt work and it reboots when the screen turns off.

The power button does turn off the screen(then it reboots), and volume buttons do work.

Can't really do anything to get adb working because otg doesn't work.

Any suggestions to fix this.

Greetings to all,

I am looking for the firmware for a tablet Onn 8 Kids (2021) and chip mediatek MT8168 with android 11, the tablet was blocked to update the system to android 12 and did not finish the installation correctly. I tried to install other systems but all I have found are for chip mediatek Mt8163 and sp flash tool alerts me that they are not compatible. The tablet does not start, I connect it to the pc and sp flash tool recognizes it and I can format and install system, but I can not get it to start.

Can someone please help me with the search for stock firmware for this tablet? Or any suggestions on how to regain access to the tablet?

@tek3195

@diplomatic

I have 2 Onn 8 1st gen tablets with TWRP provided in that thread.

Onn 8" 1st gen - ONA19TB002

Onn 8" 1st gen 100005207

In the past I have used the stock images posted here for the Onn 8" - ONA19TB002 to reflash the rom in sp flashtools.

Does anyone have the stock rom for the Onn 8" 1st gen 100005207 to flash in sp flashtools?

The older one for the may work but But I hate to try that one unless someone has successfully used it on the Onn 8" 1st gen 100005207.

The newer one: Onn 8" 1st gen 100005207 has the same Android version and kernel version, but the security patch date is much newer. In addition the laucher in it is called Quickstep instead of Launcher 3.

I test the latest Magisk debug and and newer test action builds on the Onn 8" 1st gen 100005207. The only original backup I have it my saved TWRP files.

Recently when I boot into TWRP it will not decrypt the data and asks for a password. My lock screen pin for it does not work, nor default password I found in a net search. I can only delete data and or internal storage then TWRP restore the boot, system vbmeta, and others then setup Android again and it works but I can only restore or backup in TWRP using externalSD card only. I even tried reflashing TWRP recovery in fastboot and that did not solve the decryption problem.

In the past TWRP worked fine all of the time.

On my older Onn 8" 1st gen - ONA19TB002 tablet, I test Magisk Delta builds and TWRP data decrypts just fine, as normal.

Anyone have any Ideas how to solve this?

Thanks

Update: I solved the TWRP decryption. It was a stupid mistake. I had reflashed twrp-3.3.1-0-ONA19TB002.img, instead of twrp-3.3.1-1-ONA19TB002.img.

However, I would still like to find a sp flash flashable rom for the Onn 8" 1st gen 100005207.

Thanks

[Walmart Onn Tablets General] martyfender:
I see that my onn 8 has a wireless update, dated 2019-11-11. It states that it will download and boot to recovery and install. My guess is this will fail since I have the latest twrp for this device installed. How can it be installed, if that is the case? The download state is at100% right now. Does anyone know how to proceed from here?

Thanks
[Walmart Onn Tablets General] NFSP G35:
When it finishes downloading, if you wouldn't mind sending me the OTA, I can add it to the collection :good:

As for installing it, you'll probably need to restore the factory recovery first, then let the update run, then put TWRP back.

Have you modified any other partitions? System? Boot?
[Walmart Onn Tablets General] martyfender:
I can't seem to find the update.zip. It downloaded then rebooted to twrp, since the stock recovery was not there.

Yes, the recovery partition was resized in spflashtool, to be able to apply a pre-release version of the twrp provided to me. I don't think it was resized when the release version of twrp was flashed. A week or two ago I had restored the stock recovery and tried to apply your update.zip provided here but it failed. Maybe the partition size change had something to do with that?

Actually today, I got it to start the download again. I will not reboot this time. Where is that downloaded to, a temp folder, because it was apparently gone after rebooting to twrp, last time. It is listed in the wireless screen as: ONA19TB002_20191111 672.24MB Release Date: 2019-11-11.

Thanks [MENTION=4519203]NFSP G35[/MENTION]

I found it in My external SD card: /android/data/com.adups.fota/files/adupsfota. Now where to upload such a large file? I guess I could upload it to my Android File Host site. I will see. The last time I uploaded one of my Nextbook Ares 8A backups, it failed several times before it was successful.

https://www.androidfilehost.com/?w=files&flid=302384
[Walmart Onn Tablets General] NFSP G35:
If partitions were resized, then it's likely going to require a lot more to apply the update... I'm guessing you might need one of the full images and SP Flash Tool

[Walmart Onn Tablets General] NFSP G35:

Added to the OP
[Walmart Onn Tablets General] diplomatic:
It's possible, but that was more likely to do with a changed system and/or vendor partition. Those must be in an untouched condition for the update to work. Can you try to flash the original system image and redo the update? (And unmount System if doing it from TWRP.) If that doesn't work, I'll give you another scatter file to resize the recovery back to stock.

Actually, you don't have to upload the file. There's a URL you can extract from one of the xml files in the /data/data/com.adups.fota folder. Then anybody could download it to any device. This, for example, is the address for the last OTA to the TB003:

And if I flash this in spflashtool it will update my device properly with a resized recovery partition?

I had resized the recovery partitition with an early release of twrp.

I think I was given a way to resize back to default, but I would have to read back to find it in my old PM's/

I generated these from my device that I picked up on black friday I'll be working on twrp next. But to echo what others have said this device is not in the same family as the other onn tablets. It's made by a different manufacturer with a different CPU. It's also pretty bad all around it lags a lot with basic tasks I wouldn't recommend it for anyone who is planning to seriously use it. It looks/feels like a trap for the elderly to get their grandkids a tablet for Christmas.
