yeah I've tried various different things to rig the card slot as well but I had already damaged it beyond repair. You could probably just grab a generic system image straight from Google, by downloading Android studio and modifying one of those in order to conform to one of these tablets. I have been able to create them through the source code for another tablet but I never was able to get them to work. But that doesn't mean anything. It really is such a shame though not a bad tablet. It's nice it's clean and it's minimal which makes it easy to screw around with. I'd like to get my hands on a 10 inch tablet to see how those work. I need a new daily driver, but I do love my Nexus 10, but I need something that's more recent.
[Walmart Onn Tablets General] tek3195:
Recent is better. I'm having a hard time wanting to do too much with the Onn tablet. With a gig of RAM and 16 GB storage it's a bit, let's say slower, than my Tab S5e with 6GB/128GB. I don't know much about the newer Onn Pro models other than I bricked one in about 30 mins. But I was actually kind of impressed with the overall build both inside and out, and full metal back. Felt a helluva lot sturdier than the plastic ones. And still a good price.
[Walmart Onn Tablets General] moslondon:
Any update on this thread? I have the ONN10001585-A
[Walmart Onn Tablets General] tek3195:
Not really, development stopped with the first gen tablets. I don't think diplomatic or any of us owns the newer versions.
[Walmart Onn Tablets General] RyuRaiko:
will these images work with the Surf onn. gen 2 8" ?
[Walmart Onn Tablets General] LaikaXv1:
Sorry for necroposting, but I'm genuinely curious and have to ask. Any chance this could be ported to the newer Surf Gen. 2 models, namely the 10001885? I've tried with carliv and can't seem to figure it out.
[Walmart Onn Tablets General] tek3195:
Building it from source is the only way to make it as good as the first gen. Porting or cooking in a kitchen will sometimes work well enough, may be missing a function or two.

You may want to try this guide instead of Carliv. You could try it with TWRP for the first gen tablets and your stock recovery. I would first try it with the Nexus 7 TWRP that is listed in the guide.

If you cant get one to work that way there used to be a functional twrp porting tool from Hovatek. I had success with it on a huawei tablet back in marshmallow times.
[Walmart Onn Tablets General] LaikaXv1:
I'll have to get my dual-boot setup working again on my laptop so I can try this in a full linux environment, I don't really trust WSL given reports of backdoors and stuff hidden in it, but once I do I'll be sure to report back. Right now I'm using WWR and SPflashtool to take a full dump of the android 11 update so that I can patch boot.img and have magisk working on the latest update. Thanks for the tip!
[Walmart Onn Tablets General] tek3195:
You can run a full linux installation from a usb stick. Get one large enough for what you want to do and fast enough to be comfortable. Set it up with persistence and you have a system on a stick. No worry with dual boot screwing with clock and you can take it anywhere. Or wipe windoze and install Linux as main OS. Then you can run windoze from a usb with Win2USB and it's portable. That's what I have, when the need for windows comes up, I take an external ssd out of the drawer plug it in with USB3.1 and reboot. Basically it's windows-to-go from what I read, I dunno, I really don't use windows enough to know anything about it.
[Walmart Onn Tablets General] wedgimuss:
What process did you use to create the twrp recovery? I'm interested in doing the same for the 8" Pro (100003561), but "the kitchen" doesnt generate fstab. Can you give me some pointers? Attached is the stock recovery if you're feeling intrepid and generous.

Thanks.
[Walmart Onn Tablets General] tek3195:
fstab is in ramdisk/system/etc when using AIK
[Walmart Onn Tablets General] Jfuchs2007:
what onn tablet u have i have an 8 surf pro and i got the same thing
[Walmart Onn Tablets General] :
THANKS! What roms are supported for the Onn 8"?
[Walmart Onn Tablets General] tek3195:
These are for the first gen tablets. If you are using a first gen tablet there are a bunch of GSI images you can run.
[Walmart Onn Tablets General] :
What generation is mine? I got mine within the last few months..
[Walmart Onn Tablets General] tek3195:
1ST GEN are the ones with model numbers ONA19TBOO2 .....03 ......04 . 2ND GEN have model numbers that do not start with ONA19TB such as 100003562. I believe that is it, not sure if all 2nd gen have the Surf name or not, first gen was not surf.
[Walmart Onn Tablets General] :
Ok well then mine is 2nd gen
[Walmart Onn Tablets General] Jfuchs2007@:
If anyone has the link firmware for my Onn 7 100026191 (Android 11 GO) Please share it to me bc it is bricked
[Walmart Onn Tablets General] zkennedy1137:
Any Idea about the 8" model this is the only model number info i could find "

Onn. 100003561 8” Tablet MID8011 8 h Tablet"​

but i have found a way to make twrp run but i cant get system to mount even after running another members script called "systemrw.sh" which does enable the ability to mount the system partition in userspace with a terminal even though it is inside the super partition however i did manage to get it to see cache, dalvik cache, and data(although its still encrypted and i cant seem to mount it with the encryption key or whatever i neeed to do" anyways the only true issue with the twrp port i created is i cant get system to mount in twrp hope we can work together and maybe open some more doors with this tablet :)
[Walmart Onn Tablets General] Jfuchs2007:
I wish the 8, pro gets the android 11 go updatw
[Walmart Onn Tablets General] zkennedy1137:
i mean if we get a fully functioning twrp i dont see why that cant be forcibly installed
[Walmart Onn Tablets General] tek3195:
If it came with Android 10 I really wouldn't expect a version upgrade from Onn. Is it still getting security patch updates ?
[Walmart Onn Tablets General] zkennedy1137:
i didnt say it would be from onn haha i said forcibly
[Walmart Onn Tablets General] tek3195:
Who would you possibly get a version update from ?
[Walmart Onn Tablets General] Jfuchs2007:
How do we find the right twrp for the 2020 Onn 8 pro?
[Walmart Onn Tablets General] zkennedy1137:
This whole post is about a custom twrp for that tablet lol like porting twrp to it that is what I’m referring to I have every partition except system mounting in recovery as r/w I do have r/w privileges in user space with root
[Walmart Onn Tablets General] PseudoDistant:
What kind of firmware do you need?
[Walmart Onn Tablets General] zkennedy1137:
To clarify

*UPDATE* I have system mounted as r/w but cannot decrypt userdata. I am stuck and would love help.
[Walmart Onn Tablets General] Jfuchs2007:
I need the onn 8 pro 100003561 twrp file
[Walmart Onn Tablets General] tek3195:
There's not one! This thread was for first gen tablets. The 2nd gen tablets are nothing like them. If someone has one they cooked in a kitchen it won't be here, it would need a new thread.

How's twrp coming for the 007 model with the keyboard? 003's twrp boots fine but no touch input
[Walmart Onn Tablets General] diplomatic:
Well, you're the first to ask about it. I'm currently working on improving TWRP for the next version. I suppose the 007 support should just be a matter of switching out the kernel and model numbers...
[Walmart Onn Tablets General] remainchaos:
How do fix no touch input. Is this happening to everyone so far
[Walmart Onn Tablets General] diplomatic:
Here, try this image on the double-oh-seven, guys, and let me know how it works....

EDIT: Buggy image removed
[Walmart Onn Tablets General] diplomatic:
Really? Has no one here tried this yet? Does the touchscreen work at least?????
[Walmart Onn Tablets General] Vortell:
I mean I was going to be lazy unless we got a good ROM by I can maybe tomorrow since u have to get to a computer... I haven't even updated it at all. It's the standard Fastboot boot to boot TWRP without install right? Is the ram disk install working on the 003?
[Walmart Onn Tablets General] ragtop429:
I have the 007 model with keyboard case and I have been silently following these threads. Thought I'd go ahead and speak up since no one else has. First off, THANK YOU for your work. Lots of us out here lurking in the shadows that are using and appreciating what others do to get stuff working on our toys!

Your version of TWRP flashed just fine, and it does boot, but when I boot into recovery the touch response is opposite of what's on the screen. It loads in portrait mode, but upside down, if that makes sense. So looking at the "Unmodified system partition" screen when TWRP first boots, I see the "Swipe to allow modifications..." but I have to swipe at the top of the screen, not over the actual button to get it to respond. Same goes for all other touch. TWRP seems to be working, just that that touch response is in upside down/mirrored areas.

My tablet is unlocked, and rooted using Magisk. I will be happy to do any testing and feedback for you but just be patient with me. I generally know the basics of using ADB/Fastboot, unlocking, rooting, flashing ROMs and such but I am far from an expert like most people on here.

Expect a lot more viewing on this post from google searches. These are on sale for 55 bucks (10inch) and 28 bucks (7inch) at walmart for Black Friday. I picked up 4 of them lol

A small issue I'm having is that my Win10 doesn't seem to pickup the drivers for when this is booted to fastboot on the 10inch. In device manager, it just sees it as "Android" with the yellow warning triangle symbol next to it under Unknown devices

Update to my issue above, had to disable windows integrity check for the drivers for the device, then installed the MTK drivers from Google

As for the 007 Model, it says the file is too large to flash the recovery
[Walmart Onn Tablets General] callihn:
What about the 7" version? Walmart has them on their Black Friday Sale for $28.
[Walmart Onn Tablets General] CyberstormFox:
Tried and failed

I tried it on my 10" Onn Tablet and and also just had to learn to touch the upside-down side of the screen for your intended presses.
[Walmart Onn Tablets General] dreimond:
Anyone try any Android 10 ROMs on the tablet yet?
[Walmart Onn Tablets General] diplomatic:
Version Update

Hi everyone,

A new version of TWRP is out for the 8" and 10" models. It has major improvements such as:

Mixed adoptable/shared SD mounting

New build for the ONA19TB007

Proper landscape mode on the 10" variants

Now you can install TWRP on a locked bootloader and boot the OS at the same time

Faster bootup

Reduced ramdisk size

I've also uploaded the source code as promised. For anyone curious about it, you can now see "how I did it". :) It has a brief readme file that explains the build process. Let me know if you have questions about it.

Also, not to state the obvious, but please report any bugs with the recovery, etc.
[Walmart Onn Tablets General] Dr.Lost:
Does this work for the 7" model?
[Walmart Onn Tablets General] Xavster2:
I don't see it listed so I wouldn't try it. I just picked up a 7" myself for something to mess around with, it was only $28 after all
[Walmart Onn Tablets General] martyfender:
Thank you for this update.

There is one update method you do not mention in the op that I used. If you already have a previous version of TWRP, the new one can be flashed in TWRP by choosing the install and image buttons. I have never had any issues doing this on an older device, in the past and it works on this one as well.

[Walmart Onn Tablets General] TechX1991:
I have 4 of the 7 inch tablets lol So far, I haven't needed TWRP for anything, but I'll test on my gf's tablet today and let you all know
[Walmart Onn Tablets General] diplomatic:
Yeah, good point. That is a convenient way to update. Although I only listed methods for new installs....
[Walmart Onn Tablets General] Kodeness:
Have you gotten magisk image to flash with the manager?
[Walmart Onn Tablets General] Kodeness:
Complete noob here that would really appreciate some help. I have the 7" Onn tablet and have been struggling to root for hours using this guide.

Problem is I can not unlock the bootloader due to <waiting for device>. I've installed the 15 second adb/fastboot and turned on usb debugging and oem unlock. My pc recognizes the tablet when plugged in as "android composite adb interface" and lists it under adb devices but then when in fastboot mode nothing shows in adb devices or fastboot devices, yet in device manager it's recognized as "android bootloader interface." When searching for resolutions to waiting for device it suggests I should see an unidentified usb device in device manager to update but I only see "android bootloader interface." Automatically updating that turns it into "android adb interface" which still gives <waiting for device.>

What.

Gives.
[Walmart Onn Tablets General] martyfender:
It sounds like you need to update the platform tools to the latest version. Per the 15 sec adb page:

https://www.xda-developers.com/what-is-adb/

https://dl.google.com/android/repository/platform-tools-latest-windows.zip
[Walmart Onn Tablets General] Kodeness:
Good lord such a simple fix that I couldn't figure out. Thank you.
[Walmart Onn Tablets General] martyfender:
You are welcome. I'm glad You got it sorted out.

I went through this a few weeks ago with my Onn 8. I now primarily use Linux Mint Mate and had no problems on Linux. However, spflashtools does not work on my desktop in the Linux version for some reason.

I rebooted to Windows 7 and installed the Windows version of it and it works fine from Windows. It was then that I discovered that, as like you, fastboot was not working. It had worked fine on my Android 6 device in the past. I then investigated and found that message in that thread and updated my own platform tools to the latest version. I may have also had to change it in the device manager, I can't remember exactly.
[Walmart Onn Tablets General] Dr.Lost:
C.a n I flash the 8" twrp on my 7". I realize it is probably a no. I just figured I should ask. I've already rooted with mtk-su and debloated. Figured I'd ask if I could install twrp?
[Walmart Onn Tablets General] tek3195:
NO! I can't imagine anything but bad sh*t coming from that. They aren't close to the same devices in any way, they are just too far apart to attempt it.
[Walmart Onn Tablets General] Dr.Lost:
Understood, thank you anyways. I figured that. Stupid question really but I had to ask. I guess you dont plan to support it either?
[Walmart Onn Tablets General] tek3195:
Support would be on the OP. Someone would probably need to make the tablet available to him for him to do it. Be cool if somebody that picked up extras on black friday just to give away would send one his way. He is definately deserving of it IMO.
[Walmart Onn Tablets General] diplomatic:
Well, it could be done remotely if needed with someone else testing it out. BTW, is someone working on the 7" version right now? [MENTION=4222965]deadman96385[/MENTION]? (Mentioned in another thread.)
[Walmart Onn Tablets General] Xavster2:
I think a lot of us would be willing to test it with our 7" models myself included. So go right on ahead!
[Walmart Onn Tablets General] deadman96385:
Yeah I'll be working on it this week, unless something is really weird with it, it shouldn't be hard to do. I'll keep y'all informed.
[Walmart Onn Tablets General] nl3142:
How do you backup the crypto footer?
[Walmart Onn Tablets General] diplomatic:
[MENTION=4130318]nl3142[/MENTION], it's in TWRP backup options.
[Walmart Onn Tablets General] mrmazak:
I feel late to the ONN hype. I am receiving my 8" model today. Seems like all the readbacks and tests have been done. Great work. TY.

If I need anything, I know where to look now.

It's a small world here on XDA, [MENTION=5312578]mrmazak[/MENTION] :) Enjoy the party.
[Walmart Onn Tablets General] tek3195:
It's been a while since I have looked at the help page for fastboot, but may be worth looking at. "fastboot --help" lists some new commands and functions with latest platform tools. Or at least they looked new to me. Just a little F.Y.I.
[Walmart Onn Tablets General] Josephdbrewer25:
can someone help out? i have the ona19tb002 thats been reset to factory settings with bl locked. I need the scatter file for this model. please help
[Walmart Onn Tablets General] tek3195:
Check /system/data/misc on your device. I think that's where it was. You can also get it in the OTA thread and several other places in these Onn threads. Just hit search and type in scatter at top of thread.
[Walmart Onn Tablets General] mrmazak:
i read this before. And was shocked that it would be on device. I searched on my 8" model. it was not there
[Walmart Onn Tablets General] tek3195:
Big question is did you find it? I don't know why it wouldn't be there unless you've erased it like I have by running different OS's, Can you not unlock it a use mtk-su again? Or is it bricked or need to hit reset? More info would be helpful.

EDIT [MENTION=5312578]mrmazak[/MENTION] I just realized that wasn't you with the question. Sorry about that.
[Walmart Onn Tablets General] Vortell:
Maybe we should start a thread dedicated to the scatter files?
[Walmart Onn Tablets General] NFSP G35:
I could either host them on the thread I made for OTAs, images, etc... Or they could go with the SPTool thread
[Walmart Onn Tablets General] Vortell:
Better idea! :good: hey did you take any ota? If you did how did you install? Do I need to lock bootloader again? Can I run it in twrp? (Wishful thinking I know) Do you take ota then use magisk ota survival mode or twrp retention script... There is a bunch of ways on different devices right now.
[Walmart Onn Tablets General] NFSP G35:
Holy plethora of questions Batman!

Yes I took OTA.

Installed from stock recovery.

Didn't relock bootloader.

Can't run in TWRP.

Repatched boot image with Magisk after the update.

I did this on the 003 and 007. I had fiddled with the system partition on the 003, so I had to get an image from someone else and just did a dd overwrite for system and vendor. Then the OTA installed from the stock recovery successfully. 007 didn't need any of that since it was just stock unlocked + magisk
[Walmart Onn Tablets General] martyfender:
On my device, I knew it was there, because I had seen it in the past. I searched for scatterfile in totalcommander and it did not find it.

If you search for:MT8163_Android_scatterfile.txt, you should find it in the /system/data/misc.
[Walmart Onn Tablets General] mrmazak:
Ahhh, I looked in /data/misc only.
[Walmart Onn Tablets General] mobilityguy:
I just got an 8 inch tablet yesterday, and find I can't unlock the bootloader. I boot to fastboot from adb and use the "fastboot flashing unlock" command. When I confirm, the tablet says "unlock failed... return to fastboot in 3s".

Has Walmart gotten wise and cut off unlock capability? If so, anybody getting a new tablet should make sure you unlock the bootloader before connecting to the Internet and triggering the first round of automatic updates.

One possibility: I tried rebooting into recovery and got a screen full of Chinese characters. I could read most of them using Google Translate but missed the part about Volume Up actually executing the commands, so I may have changed some important setting before I tried the fastboot unlock.
[Walmart Onn Tablets General] diplomatic:
[MENTION=2858132]mobilityguy[/MENTION], have you enabled OEM unlock in developer options before going to fastboot?
[Walmart Onn Tablets General] martyfender:
My thoughts, exactly. I work in Walmart's electronic department and Walmart doesn't know diddley squat about this device. It is simply another device to sell.

I was shocked when I looked in our tablet case yesterday and we had sold all of our Onn 8s. when I sell tablets it is usually the Samsung or the childrens cheap, learning, I call, bumper car tablets, because they have very thick, protective outer edges on them.
[Walmart Onn Tablets General] luigi90210:
so the boot.img doesnt contain a ramdisk and the device uses the ramdisk in the recovery to boot up, obtaining magisk root is done by patching recovery.img and flashing that back to the recovery partition and then booting into recovery, however it does weird things like usb functionality doesnt work(i theorize its because usb needs to manually be enabled when booted into recovery) and you also lose recovery all together unless you flash back the stock recovery

I personally do not like that this functions like that so i am considering about getting rid of mine for a fire hd7 or something thats a little more straight forward with its magisk install

EDIT nvm i got usb data transfer working, if it isnt working for you, you need to enable it in the developer settings
[Walmart Onn Tablets General] mobilityguy:
Yes, thanks! Was this option in earlier versions of Android? I don't recall ever having to set it before, but it's been a while since I unlocked a bootloader.

The first time I installed TWRP, the stock recovery came back. I did it a second time, and it seems to have stuck. The tablet is successfully rooted.

We should thank Walmart for providing an entry-level tablet that's flashable. Intentionally or not, they may spawn a whole new generation of Android developers.
[Walmart Onn Tablets General] martyfender:
For me, that oem unlock function was first seen when I got my Android 6 devices. It was not in my Android 5 device.
[Walmart Onn Tablets General] mrmazak:
I tried to get PHH aosp-10 v207 to boot. I did not have success.

Bootloader unlocked, and still needed to flash --disable-verification vbmeta. And then gets stuck on aosp boot animation.

That part is OT , I know. But it leads me to the point.

After trying to boot aosp, this twrp no longer decrypts /data.

Edit:

Let me clarify. When I flash back to stock Rom, twrp will decrypt as expected. It is only when system has been replaced with gsi.
[Walmart Onn Tablets General] mobilityguy:
I've had a similar experience with a OnePlus 3T. After trying some magic TWRP wouldn't grant access to /data even with the correct key, even though the phone booted into the system and decrypted fine there. The only way out for me was to copy the contents of /sdcard from the system boot, go back into TWRP with /data access blocked, reformat /data, factory reset the phone, restore from a recent backup and recopy /sdcard back onto the phone. After that I could re-encrypt and everything was back to normal.

I've had other phones where changing versions of TWRP broke encryption in the same way. These days I tread very lightly when I mess with TWRP on an encrypted phone.
[Walmart Onn Tablets General] diplomatic:
Yeah, that has to do with this TWRP using the system-based vold decryption. It loads services from the system and vendor partitions to do the decryption step. In addition, this is complicated by Project Treble, which involves different interface versions between system and vendor. It's hard to say what the root of the problem is. It may have something to do with the vndk version of the stock FW. Or it might be something deeper that needs to be investigated.
[Walmart Onn Tablets General] mrmazak:
Same as other devices I have seen. Where they need system vold to fully work.

I am now trying to make way through flashing gapps on gsi with this . After completing a format and recovery reboot. I suspect it will install
