I have the 7" model which has Android Pie Go on it, MT8167 SoC, 16GB of Storage, and 1 GB of ram. Also, it uses ARMv7l instead of ARM64. See the CPU-Z screenshots attached to this post for reference of the 7" model.
[Walmart Onn Tablets General] Vortell:
So it's there any way free tool to make a backup of the 10.1 with keyboard? It model 007 ;). Sptool had seemed to be the go to in mtk for a grip of time but all the nightmares I have read about it makes me hesitate. Can a backup brick your device if using the wrong scatter file?

Either way a link to be best sptools and walk through would be neat.

Also where is ota kept before it's updated? Would like to capture it for restore ability. Got two of them for under $30 each!
[Walmart Onn Tablets General] NFSP G35:
What kind of backup? Full device backup? System? Boot? Data? Trying to restore apps?

The location will depend on whether or not you added an external SD card.

I have captured an OTA from my wife's 007 model, I just need to upload it to AFH
[Walmart Onn Tablets General] Spatry:
Get the SP Flash tool from their website, I can vouch for the Linux version! Windows versions are available too. And once again, the step by step tutorial and factory images for onn 8' and 10' are on page 20 post 192. For the life of me I cannot imagine the KB version being different from the one without... is the KB connected by bluetooth or is it plugged into the device? Either way, the kernel would provide the driver support for the keyboard, so I would imagine that the STOCK 10' backup would be fine... I could be wrong though...

My procedure for flashing on Linux:

1. ensure your drivers allow adb and/or fastboot access
2. power off the tablet completely.
3. open the spflashtool DOWNLOAD section: input the scatter file from the stock rom you will flash
4. go to the format tab, auto format flash and format except bootloader should be checked
5. press format- then push vol down on the tablet and at the same time plug into your computer
- you will see activity on the progress bar; once completed, close the green check mark.
6. Unplug tablet from computer then go to download tab.
7. press download and then press vol down on tablet while plugging into the computer
- the stock rom set takes about 5 minutes to install... when done, unplug your tablet.

When you turn the tablet back on, it will take a few minutes to load as it is performing a factory reset and it will work as it did when it was new ootb. Of further interest, you can take the back cover off of the onn and do this same procedure with the battery unplugged from the tablet... Then you do not need to press the VOL button when plugging in.
[Walmart Onn Tablets General] NFSP G35:
The keyboard version has physically different hardware. The keyboard plugs in with a physical connection, and the charge port and SD card are in a different location
[Walmart Onn Tablets General] CaffeinePizza:
Yes, at some point I'll provide a tutorial on how to perform a backup using the tools I used. The caveat is that it requires Windows to use Wwr.
[Walmart Onn Tablets General] Spatry:
For those who are anxious to get that backup tutorial, you can find one HERE at the hovatech website... I imagine that Linux users can run Wwr in WINE if necessary. It also includes a video tutorial and you may need to turn the captions on.

Edit: I can confirm that Wwr runs on Proton3.7 (should work in newer releases too) and I was also able to get it working in WINE 4.0-staging (64bit) using Playonlinux. One of these days I will try out that tutorial and see if I can get the whole thing to work without having to fire up a VM to run Windows.
[Walmart Onn Tablets General] CaffeinePizza:
That is the correct guide, but it is missing some things that are specific to this device. Wwr does not automatically extract the items.ini for you, and the scatter file has to be edited manually. The items.ini is a partition (plain text actually) that specifies to the device firmware the display model and digitizer model, accelerometer support, etc.
[Walmart Onn Tablets General] Spatry:
I kinda gathered that the scatter file was "piece work" but was completely unaware of the items.ini, anyway your previous mention of Wwr sparked my curiosity and I went online to seek a Linux alternative, in not finding one I decided to try it out in wine and it ran well... I still need to complete the whole tutorial when I get some free time later this week. =D
[Walmart Onn Tablets General] martyfender:
UPDATE: 11/5/19: I found out last night it was the Linux version of spflashtools that was the issue for me on my Linux Mint Mate 64 bit install.

I did a flash last night booted into Windows With spflashtools and it worked very well under Window 7 Home.

The version I tried under Linux was SP_Flash_Tool-5.1916_Linux. Someone else mentioned using it on Linux Mint I believe, not Mint Mate, like me. maybe I am missing something in my install. Any advice would be greatly appreciated. I hate to have to boot into Windows just to do this. Windows 7 boots so much slower than Mate. Even if it was on an SSD like my Mate install.

Thanks
[Walmart Onn Tablets General] Spatry:
The only thing I can think of is that you are missing a dependency required to properly run SPF. I am running 5.1916 on Arch Linux and it works very well. I have libpng, libpng12, android-tools, android-udev and gvs-mtp installed. I noticed there are a few tutorials online for installing SP Flash tools on an Ubuntu (or derivative) type system, a Google or DDG search should get you what you need. Good luck.

Edit:

You could also try running "./flash_tool.sh" in your terminal and see if there are any errors. It will give you a clue on what it needs to fully function.
[Walmart Onn Tablets General] CaffeinePizza:
off topic, but do I recognize your name from YouTube?
[Walmart Onn Tablets General] Spatry:
I have not released anything new in a few months... but yes, I am Spatry from the Cup of Linux show.
[Walmart Onn Tablets General] CaffeinePizza:
That's lovely! When I get a chance to writing a formal tutorial on this series of tablets, I'll be sure to write one for both Linux and Windows. I have my T430 with Arch ready to go.
[Walmart Onn Tablets General] Spatry:
Participants of this thread (and some of my own research) have taught me enough that I could do a few video tutorials of the onn myself. Since Android is Linux powered (kernel) it would fit in the format of my show.

WE NEED a good FOSS rom for this device, including an open bootloader, recovery, the whole shebang!
[Walmart Onn Tablets General] CaffeinePizza:
Unfortunately, a completely open ROM won't be possible for the device because of MTK blobs. I will be trying to port TWRP when I get time. (I'm chemistry undergrad). I spent two days dissecting this device, essentially, to figure out how the MTK flashing system works. Also, a lot of things on this device is in Chinese (items.ini partition for instance), so Google Translate with the camera feature is a godsend. I'm willing to organize some instructions and assist you in compiling some kind of tutorial, if that is of interest. I did all the work on my Windows desktop because of the Wwr software, but I'm sure it will successfully run in WINE.

Additionally, there is a 7" model, which has only 1 Gb RAM, but not much is known about it yet.

Most of the discussion around these tablets is in this thread, but it's beginning to get to be too much going on in a single thread.

[MENTION=4519203]NFSP G35[/MENTION] what I got was this,

Well technically it wasn't getting enough posting/views to get a forum but I have compromised and given it a single "General" forum. At least it will allow ew threads to be made in a single place:

Mike

I looked for new device forum request and missed it somehow. I'm surprised in a way that we got what we did. When I couldn't find correct place to post I sent my request via pm to Mike Channon. He was pretty cool I think , for giving us the real-estate that he did, but I don't think I'll try that again. Just thought I'd drop a note, cuz if you stay signed in like I do most of the time you won't know it moved.
[Walmart Onn Tablets General] NFSP G35:
[MENTION=8491352]tek3195[/MENTION], very cool. Thanks for the update! Yeah, I would have totally missed the thread move lol.
[Walmart Onn Tablets General] Spatry:
YAY! We now have our own category! Should make this page easier to find... especially as Christmas rolls around, I imagine many bargain hunters will grab one of these tablets and come here to root it... HE HE

[MENTION=8491352]tek3195[/MENTION] THANKS!

Now there can be separate threads for TWRP, Roms, tools, etc...

WOOT..
[Walmart Onn Tablets General] martyfender:
I was wondering if anyone has had similar experiences with this Onn 8 with an unlocked bootloader and Magisk installed. My memory is not so good, considering it happened a couple of weeks ago before I was hospitalized, briefly, for a life threatening event.

I found where the wireless update app was and opened it. It stated that there was an available wireless update available, dated May something of 2019. My current version is dated February something, of 2019. When I clicked update it stated that there was some kind of error downloading it. I closed the app, I believe, don't remember. Later I opened it again and it stated I had the latest update available: February, 2019.

Is this happening because it is detecting an unlocked bootloader/ root?

Any Ideas would be appreciated. Maybe it would have succeeded if I had found and run it before unlocking and rooting it.

Thanks
[Walmart Onn Tablets General] NFSP G35:
FWIW, I thought that may be the case with mine, but it downloaded an update a few days ago dated 10/15

I haven't installed it yet, but I backed up a copy of the update.zip on AFH.

...which reminds me, I think it's time to put this new forum section to good use :D
[Walmart Onn Tablets General] Vortell:
So wwr is where you got the scatter file then I assume?
[Walmart Onn Tablets General] CaffeinePizza:
Yes, but what it spits out has to be modified, or you'll end up with a soft brick device.
[Walmart Onn Tablets General] martyfender:
I have never used custom kernels before. Are there any available for this device, or does one have to also delve into the custom roms? [MENTION=5488402]DB126[/MENTION], what are your thoughts on custom kernels?

Thanks
[Walmart Onn Tablets General] CaffeinePizza:
We don't have kernel source code and project files to build a kernel for this device. However, I'm looking into this further soon.
[Walmart Onn Tablets General] martyfender:
Sorry, I knew that, I guess I was thinking of the overall source code when that was mentioned previously. In other words it isn't easy to reverse engineer a kernel?
[Walmart Onn Tablets General] DB126:
Kernel optimizations/tweaks can be powerful depending on interests and goals. A fan favorite is DT2 (double tap to wake) along with an expanded selection of governors, schedulers, etc. I generally find stock kernels to be adequate, stable and generally superior to those a few generations back. Kinda goes with the territory when optimizing for power consumption.
[Walmart Onn Tablets General] martyfender:
Does anyone know the maximum MicroSD card size this Onn 8 handles? I hope it will at least take a 128 Gb card.

Thanks
[Walmart Onn Tablets General] NFSP G35:
I have a 64Gb in mine currently and it's fine with it
[Walmart Onn Tablets General] Spatry:
I can confirm it will take 128GB - I think it takes up to 400?
[Walmart Onn Tablets General] martyfender:
If that is the case, then I may try adopted storage instead of portable storage. I have never tried it. I do know that Magisk will not work properly if Magisk Manager is in adopted storage. Is anyone aware of any other issues with adopted storage. Sorry, I guess I should search xda first, but I wanted specifics to this device>

Thanks
[Walmart Onn Tablets General] extrem0:
I also confirm it supports 128gb. I hope it does support at least up to 400gb. I know amazon's fhd 8 does.
[Walmart Onn Tablets General] martyfender:

[Walmart Onn Tablets General] Spatry:
Adopted storage prevents you from pulling the SD card out when the device is off and then transferring data from another source, this is by design. The data is encrypted so only your device can read it. INSTEAD, I use Magisk FBind. This handy little gem lets you have your cake and eat it to. Basically, you can link your OBB and Data folder to the ExtSD Card saving internal storage space AND you can also remove the card when the device is off and read it on your home computer. Unlike the play store apps which require multiple partitions to move data to sd, fbind only requires ONE partition on the sd card. Presently I am using the default FAT32.

It works very well on the 'onn'. I have my entire ANDROID folder linked to my 128gb card - Sometimes it is necessary to reboot after installing large games. It behaves much like a simlink, but since fat32 does not support these links, fbind will mount your folders at startup. It stands to reason that the SDcard is not as fast as your internal memory but I feel it is worth the small amount of loading time in order to have a huge software library installed on the tablet.
[Walmart Onn Tablets General] martyfender:
When I get a new, larger card, I may try FBind. I seem to recall you posted the other day about it, but I forgot about it. I currently use Apps2SD on a 32Gb card with a 16Gb FAT32 partition and a 16Gb EXT2 2nd partition that apps are moved to. However, I like the Idea of not having it split up into two partitions and I don't like the idea of being locked in with adoptable, even though storage is cheaper now than it ever has been.

I only have one big game installed, which I hardly ever play, most of my storage needs will be in the future for TWRP backups, if it is ported to this device. You and I know that it is being worked on by some smart people here.
[Walmart Onn Tablets General] tek3195:
Don't know if everybody is aware of this but stock scatter is on your device. Its location is referenced earlier in this thread. That is the absolute stock factory scatter.txt file which should work perfectly for flashing stock firmware img's. No mods needed and with no bricks experienced as of yet.
[Walmart Onn Tablets General] martyfender:
Thanks for reminding me. I had noticed that also after I first rooted the device.

Thanks
[Walmart Onn Tablets General] CaffeinePizza:
Yes, I forgot about this! It can probably be used with Wwr for extracting from the ROM_1 dump.

[Walmart Onn Tablets General] CaffeinePizza:
anyone else having issues with the x003 stage-lighting? It seems one corner of my display has come partially unglued from the panel and creates a dark spot. If I press the back of the tablet, it goes away.

[Walmart Onn Tablets General] martyfender:
Do I need to uninstall Magisk and relock the bootloader to install the ota update.zip linked in the stock backup thread. I restored the stock recovery and tried from there but it fail,. Some message like it was not an official update or something like that. My current rom patch date is February 2019.

Thanks
[Walmart Onn Tablets General] DB126:
Everything must be pristine to install an OTA update via conventional means. At minimum recovery and system partition; often vendor (if applicable) and others. Life gets much harder the moment you update (enable write access) for any of the above. An enthusiast's dream: hours of geeky busy work trying to reassemble Humpty Dumpty. :)
[Walmart Onn Tablets General] martyfender:
I'll just leave the device as is, because it works great without the latest patch. I'm not sure what, if any, the update.zip fixed, anyway.

Thanks
[Walmart Onn Tablets General] DB126:
Exactly. Why flash something with unknown benefits but almost certain workload and possible heartache if it don't work out like the storybook says? Let's see, found a pill on the street. Maybe I'll take it and see what happens. What could go wrong?
[Walmart Onn Tablets General] Spatry:
I would have to agree... When removing all of the bloat through ADB shell and using the FDE.AI magisk module, this performs rather well, arguably as good, if not better than any of the other roms I have tried. I have my onn pimped out nicely and it handles most tasks I throw at it satisfactorily.
[Walmart Onn Tablets General] martyfender:
OT here and a rant:

Actually, Sam Walton would be turning in his grave about the current state of Walmart. Sam was all about customer service. When Sam died Walmart went in an entirely different direction. The priority became pushing more product with much less customer service. They will say they are all about the customer, but in reality, not so much. Get the product out, push employee to the brink. Over a 3 year period Walmart got a lot of pr about raising wages, but in doing that they started pushing employees much harder. Many stores now close over night. They are pushing 1st and second shift employees to get stocking done so they can eventually eliminate the the third shift who get paid more.
[Walmart Onn Tablets General] NFSP G35:
As [MENTION=5488402]DB126[/MENTION] mentioned, edits to system will prevent the OTA from installing. I found this to be the case for me when I tried to apply an OTA. Furthermore, I lost my backup of the system partition. Big tanks to [MENTION=9936108]CaffeinePizza[/MENTION] for their backups though, I was able to download one of those, dd the system image over mine, then apply the update without any trouble.
[Walmart Onn Tablets General] tek3195:
You may consider that if some people didn't wonder what if and then try it, everyone wouldn't have been able to unlock these tablets when they did. You can't be afraid to go out on a limb, that's where the fruit is. Unless you're content with waiting for it to be handed to you, anyway. To each their own.
[Walmart Onn Tablets General] CaffeinePizza:
I mean, I bought one of these tablets fully expecting to brick it. I did soft brick my first one, 10", until I realized the items partition was important. :p
[Walmart Onn Tablets General] DB126:
There is vast space for appreciation, meaningful contribution and enjoyment between those extremes. Don't assume unwillingness to hit useful gizmos with a blow torch equates to spoon feeding tendencies. Risk-reward balance. Rooting/unlocking/modding/etc vs applying routine updates are very different things that warrent different actions, risks and potential sacrifices (including wasted time which perhaps I value more than others). I do agree with your last point.
[Walmart Onn Tablets General] martyfender:
Maybe it is just a coincidence, or most of you are college students studying for that final stretch before the semester break, but there has been a serious lack of many post here and on the xda forums that I frequent, such as Magisk, etc.

Now that twrp has been released, I think that it has much more potential for improvement without dire consequences.

I certainly am busy also, in the final stretch to Black Friday sales, or in my case, Thanksgiving.
[Walmart Onn Tablets General] CaffeinePizza:
You are correct about the college student part. :eek:
[Walmart Onn Tablets General] DB126:
I think what you are seeing is a shift away from mainstream rooting/modding as modern devices are quite capable in stock form. Once upon a time unlocking (or at least rooting) and custom kernels/roms were all but essential for enthusiasts given limitations in available hardware/roms/apps but that has slowly shifted from 'need' to 'want'. Of course, there will always be die hards who will munge everything they lay hands on but the size of that community is definitely shrinking.
[Walmart Onn Tablets General] tdawgg777:
I had no issues flashing android 9 roms on the 8 but on the 10 all roms have issues with no sound from the speakers but sound through wired & bluetooth headsets some roms have graphical issues some have bluetooth... but all seem to have sound problems... and some will not boot past boot animation.

Roms I got too boot were phh's 9, beast rom, bootleggers, bliss and liquid remix. Liquid remix runs the best so far... but on the 8 not the 10.

I can deal with the graphical issues but what I can't seem to fix is the sound issue (not coming through speakers but does come through wired/Bluetooth headsets... has anyone experienced this? Does anyone know a fix that works? I tried the flashable gsi sound fix I found on xda, but no luck

Onn8 system update

Today I restored my stock back up and there is a notification for an update. Anyone take the update yet? Curious what was changed... All it said was a bug fix in the wireless update app.
[Walmart Onn Tablets General] NFSP G35:
Which model and what's the date on the update?
[Walmart Onn Tablets General] tdawgg777:
My bad... I forgot to mention its the 8 inch... release date is Nov 11... downloading now and prepping tablet to install it. (first try ended in error... I didn't restore vendor & vbmeta I did that and have to download the update again)

File size is 652.47MB

After it downloads I'll attempt to pull the update before I install it this time.

Edit: I can't seem to find the update.zip
[Walmart Onn Tablets General] NFSP G35:
Do you have an SD card in or not? It puts the update.zip in different locations depending...

should be something like:

/storage/<id of sd card>/Android/data/com.adups.fota/files/adupsfota/update.zip

or /data/data/com.adups.fota/files/adupsfota/update.zip

I'm just going off the top of my head, I don't have my tablet with me to check.
[Walmart Onn Tablets General] tdawgg777:
Thanks. I found it. Got error again, I side loaded it so I got to see the error. Apparently my system building # doesn't match...
[Walmart Onn Tablets General] NFSP G35:
Did you restore different versions of system vs. vendor?

Also, was the version you restored on the October update or the May update?

Also also... if you can get the update.zip to me somehow, or upload it somewhere, I'll add it to my OTA/System image collection :)
[Walmart Onn Tablets General] Vortell:
I can probably pull it from my tablet if they don't since I have an idea where they put it. I was surprised a search for "ota" from root on device didn't show it. There is update.zip so it's not a full be firmware. Unless im in wrong place. I found the update.zip at root/data/data/com.adups.fota/files/adupsfota/update.zip

Here's the link for it.

https://www.androidfilehost.com/?fid=4349826312261636209
[Walmart Onn Tablets General] NFSP G35:
This is the October update for the 10" w/keyboard model, correct? [MENTION=4283058]tdawgg777[/MENTION] has the 8" and said the update was dated November.
