Ok thanks it’s also been quite sometime since I’ve messed with android. I mean really got into it. I did a lot of stuff in 2014 with the boost max I had. I had also been working as a software quality assurance engineer at that time and had a full sdk environment setup for building and running automated tests for our mobile product. But that was so long ago I don’t really remember much accept super su and tethering was the thing to do lol. Now there are so money new tools to work with I wish I had whatever MTK is using to build this software not sure if it’s sdk or some other form of android building environment. But what I am working on now is trying to strip this operating system to a bare minimum and back it up to share with everyone. Also I’m working on an AOSP build hoping to be able to deploy it onto this device I’m still learning what really can be done on these and android 10. I have hopes in starting my own Custom Roms and Deployment kits or CFW flasher / bootloader but we will see what truly can be created and achieved. I haven’t been in the software industry for quite sometime and a lot has changed. Like having to learn how to walk again.

AOSP

I think the last time I tried to compile android was for a samsung S5 the first time devs started to abandon them. People started working on them again and I just stopped messing with it. I still prefer that phone to most of the stuff coming out now. I still don't understand when removing functionality got to be a feature on high end devices.

There's a post on page 19 of this thread about somebody that managed to run aosp on the 100003562 already. I don't think that's the only person I've seen mention it either. My guess would be getting drivers is a bit difficult. That seems to be the main issue for years now.

I swear this is my single biggest gripe about phone manufacturers, and there seems to be no exceptions.
[Walmart Onn Tablets General] will160628:
The preloader was missing out of my shipping and October firmware so I took them down until I can get the fixed and reuploaded. If you're bricked the September firmware should work from what I can tell. I'm also working on uploading firmware for the 8" Pro and adding them to a folder on my GDrive. The folder is currently empty but I'm uploading as fast as my crappy internet connection will allow. Here's a link for when the files finish.

[Walmart Onn Tablets General] TheHeroBilly:
does anyone by chance have the latest one that just released within January?
[Walmart Onn Tablets General] NFSP G35:
For which model?
[Walmart Onn Tablets General] TheHeroBilly:
I apologise, I have since bricked and returned the 10in tablet, the root on these is fairly unstable and honestly it wasn't worth the time to keep them working
[Walmart Onn Tablets General] will160628:
Got all but the earliest firmware for the 8 & 10 uploaded. I also managed to pull the update.zip for the 8" December 2020 update if anybody is interested in it. Its in the 8" december folder with the backup. I had a time applying it on my moms tablet (its rooted). It kept erroring on a "sideload" folder. I believe restoring back to complete stock would have fixed it but I pulled a backup off the new one I got for my niece and used it instead. Be on the lookout on the pro models for updating issues after root. Might just be that tablet though.

The earliest 2 backups should be up in a couple hours. I'm using cellular to speed up the process and avoid my crappy DSL.

EDIT: All uploads for both tablets are completed. Every OTA I've gotten is available through those 2 gdrive links.

EDIT2: Just got the 12-18-2020 update today so I'm uploading that firmware now. I also managed to pull the update.zip for it and its already finished uploading. Just a warning if your rooted that you may have to do a restore before trying to apply the update. I had to for other issues anyway but updates don't seem to want to apply for me without restoring the stock firmware.

I've tried downloading this twice. Windows throws the following error when extracting the contents. Is the upload corrupt, or is my machine (aka "me") being stupid?
[Walmart Onn Tablets General] Doomwake:

Download

Try it please, portable version if you don't want to install
[Walmart Onn Tablets General] notorious.dds:
That did it. Thanks!

You wouldn't happen to know of a backup for the gen2 100011885 8 inch, would you?

My tab's currently bricked (hard) and I am desperate for a working backup with the scatter file and preloader..
[Walmart Onn Tablets General] tek3195:
Downloaded and uploaded to my Mediafire account. Both in same folder. https://www.mediafire.com/folder/nyv40qvb98hu7/Onn_Tablets. @NFSP G35 if you want to add them to OP let me know if I need to link them seperately.
[Walmart Onn Tablets General] appleknight:
i need stock for mt8168 100011885, ive been all over and maybe im just not finding it? my buddy bought a returns box from walmart and this tablet is asking for the previous user's gmail info even after several hard resets, any help would be great!
[Walmart Onn Tablets General] will160628:
This may sound strange but you should be able to pull a backup with SP Tool and WWR MTK. In WWR there is an option to create a blank FRP file which would fix your issue if you load that FRP.img file in fastboot or SP Tool. The option you want in WWR is "Collect Firmware for hard reset" under Assemble Hardware under the Auto mode tab. I think I have one of those tablets around here somewhere. It had some battery issues so I kind of laid it somewhere and forgot about it. If I can find it, I'll try to pull a blank file for you. It's not terribly hard to pull a backup on mediatek devices if you want to try it yourself. There are numerous youtube videos about using SP Tool.

Sorry I don't have the tablet in front of me to give you the file and exact commands.
[Walmart Onn Tablets General] will160628:
I kind of got distracted playing with a 15" type C monitor on my phone so I haven't messed with my tablets much lately. I saw an update when I turned on my 10" pro the other day so I pulled a backup and it's uploading now. The update.zip file for 3-3-2021 is also in that folder with the backup. I imagine the 8" Pro likely had an update too. I'll try to get ahold of my mom's tab and pull those files soon.

Thank you all for all the work in putting this together cause of it was able to unbrick my onn table 100005206 but can't unbrick onn 100015685-a link on that forum is dead
[Walmart Onn Tablets General] TULOA:
I was curious if anyone knows the steps for pulling the image from a 100003561 8" onn tablet?

Looks like there was an update from the one on here and I dont mind pulling it and hosting it somewhere but I dont know how and cant find a guide so far.
[Walmart Onn Tablets General] tek3195:
Been a while since I've messed with an Onn Tablet, but do they no longer store the OTA on the sd card prior to installing ? Used to be able to postpone the update after it downloaded and just copy the OTA.zip from the updater app folder. OTA had all that was needed to unbrick without need of pulling firmware. Have no idea what the new ones are like, but should still be able to just grab ota before post-install deletion.

edit: have to get someone to grab ota before it installs
[Walmart Onn Tablets General] TULOA:
I am not sure if it came this way or not. But I suppose this means that I cant get it myself then.

Dang lol.

Do you suspect there would be a difference in the boot.img files from an earlier update? I am basically trying to get root and if they shouldnt be different then I could use one from the end of last year.
[Walmart Onn Tablets General] tek3195:
Man on the first gen tablets I kept the very first update and would unbrick with that rolling it back and then letting it update again. I would use an older one if I were trying it. If boot has changed to the point of not working then roll it all back if you have access to a full ota. Remember all my experience was with first gen models, I honestly couldn't count the number of times I had to unbrick. Must have been somewhere close to a Metric ButtLoad of flash files. Yeah, I would try an earlier version, but that's just me, a recovering flash-aholic.

The first gens would or did at one point change partition sizes for different partitions. Boot could definitely change or could very well be exactly as it was in earlier version. Would be best to work with full ota if you can.
[Walmart Onn Tablets General] TULOA:
Ok I can try it. I do have an earlier full ota but wasnt sure if it was gonna work on this being newer. I will give it a shot and report back later today.
[Walmart Onn Tablets General] TULOA:
Yeah it failed. Now it is stuck looping the Onn logo and going blank.

What would be the process for the 100003561 to get it back to the full earlier OTA?
[Walmart Onn Tablets General] tek3195:
Take images from ota and flash in spft would be first guess.
[Walmart Onn Tablets General] TULOA:
Yeah I used its scatter and files and its working again. And I can now get the update and then I will share the files to mega or something and link them in the firmwares page.

Edit: I used the How to flash section of this post: https://xdaforums.com/t/how-to-unlo...-walmart-tablet.3945284/page-10#post-80574967

I also had to use version 5.2104 of sp flash for it to work.
[Walmart Onn Tablets General] tek3195:
Glad you got it, I figured it would work, there is a full dump of the 10" ...3562. I would imagine it would work on your ..3561 with an edit or two. For emergency use only that is. I'm talking about rescue of a dead brick. And would of course use diffoscope or at least cmp to find differences. Now that I've said that, which was too much, don't do it. Never flash any files that are not for your device, firmware files for a different device, no matter how similar almost always ends badly.

From looking at updater.script I would also avoid altering anything with system, metadata, product or vendor, those are dynamic partitions. May be that I would only flash them with ultraflash enabled and with super.img. I am only talking about brick recovery if needed in future. Never flash incorrect anything to your device.

Yeah caffienepizza had the only guide that I was ever able to use to make spft work. I don't use it if possible, I have other service tools and paid software so I don't have to use it. I despise it.
[Walmart Onn Tablets General] TULOA:
Yeah. I was hoping to get magisk on here but sadly it looks like when I patch the boot.img from the firmware and send it back then flash it with fastboot even with all unlocked it bootloops.

I will have to keep digging to see what I am missing to get this to work. Now that I am on the same version as this backup and I have the scatter and all that I should be able to get this at some point lol.
[Walmart Onn Tablets General] tek3195:
When you patch image with magisk, does it show ramdisk yes or no ? If it says no then it needs to patch recovery instead of boot.
[Walmart Onn Tablets General] TULOA:
Ramdisk does say yes.

I am going to try a few lines to disabled integrity checks and see if it helps. I forgot about them.

Edit: Also finally got the update prompt and I have delayed it. But it seems they are not storing the data to the normal /sdcard/android/data/<appname>/files area.

I dont remember its full app name as I had to shut it off to ensure it doesnt update. The scatter shouldnt change though right? Couldnt I back it up with that scatter file from before after the update?
[Walmart Onn Tablets General] tek3195:
Scatter is questionable. Didn't use to be but now with dynamic partions and ota's altering part sizes as needed the scatter can definitely change since it has linear and physical start addresses and partition sizes. For the most part I don't think it is something that happens often. For some devices it would be never. Think about how likely they are to push an update other than security and bug fixes, They are working on next project and not interested in new features or functions for an update to an old device. Anything that's not the new project they're working on is old to them.

You can back up with that scatter, but I never really got the point of the backups if one has ota or firmware to recover device with. It is too easy to sync data and data backups to a cloud. Something goes wrong, restore device to like new condition and pull data to it. Not trying to make physical backups daily or three days. That's just me though, I don't keep much on any of these droids and nothing like online banking or anything I could lose. Some credit card numbers stored in some browsers, those can't be lost they're synced to 23 other devices I've signed in on this month.

Yeah you should be able to back it up with that scatter.
[Walmart Onn Tablets General] TULOA:
Ok so the missing step was when you go to send the magisk patched img you need to do these:

"fastboot flash --disable-verity --disable-verification --skip-reboot boot /path/to/your/magisk_boot.img"

then

"fastboot flash --disable-verity --disable-verification vbmeta /path/to/your/vbmeta.img"

The vbmeta.img will just be the one from the rom you are on. So im my case from the full firmware image i was using with no changes needed to it.
[Walmart Onn Tablets General] tek3195:
So, you got it working ?
[Walmart Onn Tablets General] TULOA:
Yeah. Fully working and with hiding magisk is passing safetynet.
[Walmart Onn Tablets General] tek3195:
Cool, if you pull recovery.img I'll see about porting TWRP for it.
[Walmart Onn Tablets General] TULOA:
Is there an easy way to do that? I assume use SP Flash to pull the start and length of the listed recovery?

I could still use the needed normal steps however I will attach the recovery from the firmware zip I am using now.
[Walmart Onn Tablets General] tek3195:
You can use dd to get copy from PC or on device with terminal emulator.

For PC

adb shell
su
dd if=/dev/block/bootdevice/by-name/recovery of=/sdcard/recovery.img

you can change path for destination to place it in your Download folder instead by using

dd if=/dev/block/bootdevice/by-name/recovery of=/storage/emulated/0/Download/recovery.img

To use terminal emulator on device you just eliminate the adb shell command.

I'll just use the one you put up though.
[Walmart Onn Tablets General] TULOA:
Ok and yeah I didnt think about that. I need to get the update installed and see if I can keep root or repatch the boot.
[Walmart Onn Tablets General] TULOA:
Soo... Oddly enough it seems to be failing to install the update now.

I have the update zip which has a scatter file. Can I just flash it with SP Flash Tool and not lose data?

Edit: Ok it wont attach. Ill upload it elsewhere one moment.

Edit2: https://www.dropbox.com/s/tw55t7s7b3korq2/update.zip?dl=0
[Walmart Onn Tablets General] tek3195:
I don't know if you can flash with spft and keep data or not. You should be able to flash it though.
[Walmart Onn Tablets General] TrueChart251:
Heya folks, im not too new to this, how does one flash the stock updates to the tablets, fastboot right??

edit: i cannot get into the tablet literally left it alone to boot for 3 days, nothing happened, did not boot into system, left me at the boot animation
[Walmart Onn Tablets General] TULOA:
It depends on where and what kind of stock image.

From what I have seen you want to use SP Flash Tool. The image should come with a scatter file.

Also tek3195. I cant get the update to install and I will prolly have to use the scatter and the images in the update zip to update. Theoretically I shouldnt have to lose data but the update isnt enough to make me want to deal with that yet even though it only has like a couple of apps lol.

I did swap the nav bar buttons so it would be more aligned to the Samsung line of phones I was used to though. I will wait for the recovery though so if nothing else I should be able to backup the data.
[Walmart Onn Tablets General] TrueChart251:
Now my next question is what happens if I can't even get in to turn on OEM mode, am I screwed? Also I don't have a recovery mode, only Factory Mode
[Walmart Onn Tablets General] TULOA:
Assuming the device is unlocked you just need to get SP Flash tool I had to use version: v5.2104_Win

You need to extract the firmware image to a folder and then copy the scatter in with the firmware contents if its not already. Then load it and it should mention a path to the img for each partition and it should be stored where that scatter file is.

Assuming you have the drivers installed for the MTK USB drivers you go to choose for the scatter which should look similar to one of these filenames and choose it:

100003561_Android_scatter.txt

MT6765_Android_scatter.txt

In some cases it could be scatter.txt

Then hit download and then with the tablet off you connect it and in my case it started the process from there. Otherwise you may have to tap power or hold power and volume down.

Beyond that I suppose people here would need to know your model to help ya further.
[Walmart Onn Tablets General] TrueChart251:
Yeah I'm screwed this is my brothers tablet and he's not very tech savy, so OEM wouldn't be on anyway so unlocking it is impossible. Its a 10.1 Gen 2 100011886 (MT8168)
[Walmart Onn Tablets General] TULOA:
I suppose not necessarily as I could be wrong. But I am not sure on these tablets.
[Walmart Onn Tablets General] TrueChart251:
Ah ok, guess I'll wait around here for awhile lol
[Walmart Onn Tablets General] yadada23:
i'm looking for a pre mtk-su break update stock backup to flash for the 100005207...every link i see thats hosted on it has been pulled mainly by google. Does anyone have the stock image files to the tbbvnc100005207??
[Walmart Onn Tablets General] chris1892006:
I know I should have read the whole thread but I cannot seem to get it to flash. I installed the driver. Can someone link me to a working USB driver? Also I have my 100003562 10.1" tablet off when I plug it in to flash. I plugged it into the USB 2.0 port if that's correct? Thanks
[Walmart Onn Tablets General] chris1892006:
Can someone help me flash my 10.1 Pro 100003562? I keep getting this error.
[Walmart Onn Tablets General] TULOA:
If it fails try with it off and plugged in holding volume down and power. I had to do that a couple of times for mine.
[Walmart Onn Tablets General] TULOA:
Hey tek how is the TWRP coming for the tablet? Would still be nice to have to make a backup with it.
[Walmart Onn Tablets General] Real1337:
My 100003562 is stuck on Android 10 20201217. It won't pick up the 20210303 OTA for some reason. Anyone know how to manually download and install?

Thanks.
[Walmart Onn Tablets General] RyuRaiko:
I am looking for a stock boot.img for the ONN 8" Surf Gen 2 100011885 Android 11 tablets if anyone could provide a link to one that would be amazing
[Walmart Onn Tablets General] wedgimuss:
TULOA, I've got a bricked one I'm at a loss to recover. Can you explain in a little more detail how you flashed yours to bring it back? I've pulled your files, but the same version of SPFT says the scatter file format is invalid.

Any help you can offer is greatly appreciated.
[Walmart Onn Tablets General] TULOA:
Try the below scatter from an update I pulled and should have used.

I needs to be the same model as mine to work so it has to be a 100003561 onn tablet. Otherwise ya might need to find a scatter someone else used. But its been so long since I did mine I am hoping these are right:

Scatter: https://tpras.com/100003561_Android_scatter.txt

If you need the recovery files let me know and I can get you the ones from 12/17/20 but it will take a bit as its big and I need to finish compressing and uploading the file.

Edit: If you are gonna root it make sure you run the following commands in there or it wont boot:

"fastboot flash --disable-verity --disable-verification --skip-reboot boot /path/to/your/magisk_boot.img"

then

"fastboot flash --disable-verity --disable-verification vbmeta /path/to/your/vbmeta.img"

Which was the reason I had to do this myself lol.
[Walmart Onn Tablets General] wedgimuss:
I think the preloader is completely hosed. I'm not getting anyting going with the files I have. Any last minute advice before this thing goes flying into the bin?
[Walmart Onn Tablets General] TULOA:
Yeah mine was a pain in the butt. The thing with my model is i had to do this:

Try with it off and plugged in holding volume down and power. I had to do that a couple of times for mine.

This was the only way to do it on mine.
[Walmart Onn Tablets General] wedgimuss:
Your new scatter references files not specifically named the same way in the dropbox files I pulled. Have you got a new archive I can pull that brings it all together?
[Walmart Onn Tablets General] TULOA:
Yeah try this archive and let me know how it goes:

Recovery Archive

ya may need to put the scatter file in that path once extracted then use the scatter and it should be good. otherwise I will be home soon to see how i did it.

Edit 2: Reuploaded to google drive since the file is pretty big. Dont wanna slam my server lol.
[Walmart Onn Tablets General] wedgimuss:
You, sir. Thank you. 🙏

Great success.
[Walmart Onn Tablets General] wedgimuss:
@tek3195 Any chance you've ported twrp for this device? I'm willing to do some testing with mine now that my spare is alive and well. (thank you @TULOA)
[Walmart Onn Tablets General] wedgimuss:
I took a stab at it. I don't understand what's supposed to be done with the device-specific fstab that's usually generated for other models during the porting. It's not being generated from the stock recovery on this model.
[Walmart Onn Tablets General] tek3195:
I haven't done anything with it really, in and out of hospital. But recovery.fstab should be in /ramdisk/system/etc. If you try working with it in AIK you may want to pay attention to the first_stage_mount flags and the multiple vbmeta. I haven't had to deal with them before so don't know about them.
[Walmart Onn Tablets General] wedgimuss:
I'm close. I've made a living using Linux, but the fstab instructions out there are pure sh1t3.
[Walmart Onn Tablets General] tek3195:
you have to edit the fstab making the factory one with the twrp flags. there should be no mention of tegra.3 it should be your device name.

once you get the fstab worked out you will have to format /data when you first install recovery.
[Walmart Onn Tablets General] wedgimuss:
Yeah, the fstab on these is all f*cked and cryptic. I'm going to need to get root and see how partitions are mounted before trying put a twrp version together.
[Walmart Onn Tablets General] tek3195:
Not sure I know what you mean by that. The partitions are mounted exactly as the fstab has them. If you mean the flags and what they actually mean, I would search source.android and TWRP threads for the flags and which partitions are needed and not needed for recovery. It used to be that we could get away with only 5 partitions mounted in recovery but those days are long gone.
[Walmart Onn Tablets General] TULOA:
Reupdated my link above so anyone with the link can access it. Sorry about that lol.
