That's right I have the 8 inch... it was on the May system that was on it out of the box... never got an update notification when I first got the tablet. As soon as I installed twrp I made a clean back up of the tablet partitions (except recovery). When I went to update I restored my backup and flashed the stock recovery (downloaded from op's drive).
[Walmart Onn Tablets General] Jiharu Ikumiya:
Hi, I just bought the ONN 8 last night and as far as I've been able to make it in the process of this is installing twrp and unlocking the boot loader

Problems/Questions:

I believe the original recovery keeps overwriting twrp, why? (Am I missing a step?)

I can't install a ROM from twrp, just says that my zip is corrupt. (Wrong ROM?)

If we're running 9.0 how do I get xposed onto it?

Any help would be appreciated, sorry I'm fairly new to this. Thank you guys.
[Walmart Onn Tablets General] CaffeinePizza:
When I get a chance, I'll do a dump with the newest 11/11 OTA that went out for the x002 so it can be added to the other thread.

Does mtk-su still work on the latest update or did they patch it?
[Walmart Onn Tablets General] DB126:
I think that's the question everyone as waiting to get answered. I ain't gonna update until mtk-su is confirmed working.
[Walmart Onn Tablets General] CaffeinePizza:
Well, for the x002 and x003, my dumps of the stock firmware include the boot.img which can be patched in magisk app and flashed with fastboot, assuming your bootloader is unlocked. mtk-su is not needed.
[Walmart Onn Tablets General] DB126:
That's great for those who have gone that route. I opt to remain on stock (locked) and use mtk-su on rare occasions when root is needed. I find stock performance is acceptable and don't have to play games hiding root from financial and streaming apps. For me it's the perfect balance as the burn to spend untold hours messing with gizmos has long passed. That said, I still want absolute control when needed (hence mtk-su).

If you enter fastboot with hardware buttons that's it. It stays mid-screen or so with the arrow pointing at fastboot. You have to select it with volume - for it to actually go into fastboot. There is no indication as to whether you've just stopped scrolling or made a selection I am NOT a fan of what I guess is what I see people referring to as bootloader screen. If you enter fastboot with "adb reboot bootloader" fastboot will be in x-small font bottom left of screen.
[Walmart Onn Tablets General] nl3142:
That's good to know, I was planning on picking one up to replace my current 7 inch Tab 4 (which is still stuck on 4.4). A couple more things, does it pass safetynet with magisk installed and does adoptable storage (using the sd card as internal memory rather than as a separate drive) work?
[Walmart Onn Tablets General] DB126:
Several method including one you quoted:

>> Tablet connected to PC use "adb reboot bootloader"...
[Walmart Onn Tablets General] tek3195:
Yes and Yes . That is also including EdXposed being installed.
[Walmart Onn Tablets General] martyfender:
I'm not sure if it is true with this device, or not, since I don't yet own one, but on my Nextbook Ares 8A tablets I found that simply enabling the option to unlock the bootloader in developer options, was enough to unlock. Originally, on my first tablet, I had used the option in fastboot to unlock it: fastboot flashing unlock, I believe.

If someone builds a working TWRP for it, I think I will pick up one of these 8" tablets.

Thanks
[Walmart Onn Tablets General] NFSP G35:
It's unlockable, and I was able to splice together a TWRP image that would at least boot... which means getting a working TWRP is just a matter of time/effort.

I haven't had much time to work on it yet, but I was going to take another stab at it and see if I could correct the issues I was having with my Frankenstein TWRP while also trying to build one proper.

You should go ahead a pick one up. You might even try putting together a TWRP image yourself if you have some time, patience and are comfortable working in a Linux environment. Because it's definitely possible.
[Walmart Onn Tablets General] martyfender:
[MENTION=4519203]NFSP G35[/MENTION] Maybe if I get another drive and setup a full Linux system. I have been running Linux Mint Mate for over 2 years from a High Speed, 16 gb USB thumb drive I created with a persistent, casper_rw partition. The problem I have in using it for dev, is I only have 2 gb of space left.

To download the git repo for TWRP requires a huge amount of space, from what I remember when investigating it for my Nextbook Ares 8A tablet in the past. Plus I couldn't temp root it to pull the kernel. Ended up paying someone for his, which I have a link in my Ares 8A root thread for.

I rarely ever boot with the internal HD into Windows, anymore, but I need to keep Windows 7 on it. Partitioning and duel booting is not really an option on that 500Gb drive without loosing alot of files on it.

Maybe I will buy one of the tablets anyway. One question,though, is this the exact command I need to enter to backup the boot.img and do I do that from a terminal emulator on the tablet, or do I do it from a terminal started from my Linux PC with mtk-su?

dd if=/dev/block/by-name/boot of=/sdcard/boot.img

The other thing I forgot to mention was that I have use AIK to modify boot.img's but my only attempt to try to do a modification of my working TWRP did not work, but that was only a brief attempt as the mod was not really that important at the time.

Thanks

UPDATE: I unpacked TWRP v3.1.0-0 for my Nextbook Ares 8A in AIK, ui.xml has: resolution width="1080" height="1920", is this the same for the Onn tablet? If so, maybe if I provide you with that ui.xml file, it will work in your twrp. I could also provide any others such as portrait.xml and splash.xml. Done. My guess is that the proper permissions may also need to be set for the files. There are font, language files and images in that twres folder also that could be useful. I'm not sure what version of TWRP yours is so some of those could potentially have changed.

I don't think that other files will be useful in this recovery, since The Ares 8A's are Intel x86 devices. Please let me know if I can provide anything else. The twrp.zip contains the font, language and image files from the unpacked twres folder, also.

I just had a thought, you are on the 10" tablet, so this may be all in vain. I do know some 10" Ares 10A users were able to use my recovery, but not sure how it worked for them, apparently enough to be able to use it, though. I looked it up and the Onn 10" has a 800 x 1280 resolution. I see the resolution listed in both the ui.xml and splash.xml files. Maybe just changing those values to 800 x 1280 resolution will be enough. Let me know how it goes.

Thanks
[Walmart Onn Tablets General] NFSP G35:
This is correct, but don't forget your recovery image as well!

Updates (such as they are) on my "progress"

I decided to have another go at building TWRP instead of repacking with AIK.

So I used TWRPbuilder and pulled down minimal omni sources on the 9.0 branch, fought with it for a while, then finally got it to build but it was 19Mb which was never going to fit in a 16Mb recovery partition, so I started over with the 8.1 branch, and even after stripping it down I could only get it to 17Mb. So I started over yet again with the 7.1 branch and was finally able to get it to finish building and produce a 14Mb image, which I then flashed (via dd method) and it didn't boot... So I re-flashed it via fastboot... Still no joy. So back with the stock recovery image again, and I'll go back to the drawing board.
[Walmart Onn Tablets General] martyfender:
For recovery, would it be:

dd if=/dev/block/by-name/recovery of=/sdcard/recovery.img

Thanks, I updated my post with some files which could be useful via the AIK route. Out of curiosity, how much approximate disk space is required to put TWRPbuilder, other required files and pull down the sources? Is Android Studio required, also? TWRPbuilder something new, that wasn't available when I looked into it for my Nextbooks. Here is thread I got info from, by the TWRP author:

https://xdaforums.com/showthread.php?t=1943625

I do have a new 250 SSD I bought at Christmas time, but have never installed it. I did plug it in with a USB adapter and install Linux on it. I haven't booted it up since, or installed it in my desktop, since my current setup has worked well and I guess I have been a little lazy to get a new drive setup. The SSD should be much faster, though.

Anyone use both the Onn 8" and the amazon HD 8? How do they compare?

I read a review somewhere that claimed the Onn screen is slow to respond to touches.
[Walmart Onn Tablets General] martyfender:
I don't yet own the Onn, but tonight before I left the store that I work in, I tested the touch response on the display model and the touch response seem good to me. It has a 1.3 MHz quad core, ARM processor.

However, the only other Android devices I own are Nextbook Ares 8A's, Intel x86, 1.9 MHz, Android 6.0.1 tablets, which were in the same price range. I am on the verge of buying one, even though I don't really need it, I am just looking for a new challenge to put Magisk on, with a newer OS to play with.
[Walmart Onn Tablets General] DB126:
I own both. The Onn is equal or superior in all important characteristics except two: audio quality and aesthetics. No issues with touch sensitivity. I generally run my Onn unrooted as the stock Android 9 ROM is clean and lean. No futzing around with FireOS; fully usable right out of the box.
[Walmart Onn Tablets General] * Kara *:
I have both. My Onn has the Google apps disabled, the HD 8 (7th gen) has the Amazon apps disabled, and both have my user apps set up identically. I have noticed that the Onn's screen is a bit less responsive, and the system overall a little more sluggish compared to my Fire. The Onn also runs a little hotter, and the battery lasts about half as long. Still, though, for $64 I can't complain. It is nice having nearly stock Pie (I removed the Walmart softkey on the nav bar through adb, and disabled the included Walmart apps). I'm not sure which one I'm going to use as my main tablet, as both have their pros and cons. I still have an HD 10 waiting to be tinkered with, too. :o
[Walmart Onn Tablets General] DB126:
The Onn sluggishness is likely due to a large zram allocation with an aggressive swappiness setting. I dialed back swappiness to 10 via temp root which strikes a nice balance for my use case. Overall I find the Onn screen a bit brighter with more favorable color representation, but that could just be a sample issue. I agree with your drain observation but at the 70-75% level which closely mirrors battery capacity differences.
[Walmart Onn Tablets General] NFSP G35:
Sorry for the late response... For 7.1, my directory is under 10Gb.

8.1 is about 20Gb and 9.0 is about 30Gb
[Walmart Onn Tablets General] martyfender:
Have you had any better luck with TWRP?

I just installed Linux Mint Mate 19.1 (based on Ubuntu 18.4) on my SSD and am thinking of going back to 18.3. There are just to many issues and hoops one has to jump through that I didn't on 18.3. I'm not sure if I want to install all that is required to build TWRP, that is a huge amount of disk space!

If need be, I can take mine back stock then relock and apply update. Find out if mtk-su still works as well as fastboot and unlocking with the update. If anyone else can confirm all of it still working let me know soon so I don't do all of it for nothing. Let me know?

Try "fastboot oem reboot-recovery to prevent overwrite after flashing TWRP.

I don't understand how you're trying to flash a rom with twrp if stock were overwriting it. What rom zip are you trying to flash? I am not aware of any ROM's for this device other than GSI's which are flashed by image unless someone has put together an installer to zip it up with.

Use Riru core and EdXposed from magisk manager to get Xposed working on Onn firmware. If you switch to a GSI leave Xposed alone as it does not work well with some of the changes made to make the gsi work. With the customization and options available with the gsi's there is really no need for Xposed and gsi maintainers do not want to hear problems or see bug reports from trying it. Stock rooted Onn gave no problems with EdXposed via Magisk Manager when I had it installed.

Use sim tool or something small and press reset, it's just below power button. As soon as you let go of reset hold power and volume+ until you get bootloader screen. Volume+ to scroll and volume- to select fastboot. Once in fastboot follow instructions by [MENTION=8132642]diplomatic[/MENTION] in the twrp thread for our device. The commands for fastboot are really simple but must be entered correctly, you have to make sure you cross your t's and dot your i's and not the other way around. Are you sure you unlocked it and that it is flashing the image ? Next attempt get a screenshot of fastboot output so we can see what you're doing or not doing that's causing problems. All three installation methods that diplomatic lists work spot on and the recovery is next to perfect, but just in case something went afoul downloading twrp-recovery.img erase the one you have and download a fresh copy before flashing again. Hang in there, you'll get it.

Also make sure you download correct image for your device: 8"=002, 10"=003, 10"w/kb=007 I believe that's the pecking order for them.
[Walmart Onn Tablets General] diplomatic:
Yeah, mtk-su still works on the October update on the 10". Tested it myself. So it's a pretty safe bet it works on the other models as well.

Did you use magisk install after ota feature?

I have no idea what he uses, but I'm guessing probably not. I would imagine he is a diehard mtk-su fan. Again, I'm only guessing.
[Walmart Onn Tablets General] DB126:
Appears the OTA update server/service is offline and has been for awhile. I've been holding off on applying the 191111 build until mtk-su vulnerability status was determined. Opted to go for it earlier this week but url no longer resolves. I suspect no one is watching the hen house; will probably rematerialize at some point. Kinda what you'd expect from Onn and Wallyworld.

[Walmart Onn Tablets General] CaffeinePizza:
All right, boys and girls, here is mtk-su working on the 20191111 stock firmware, since I see posts of concern of whether it works or not.

I took a screenshot of a root shell on the x002 with the 20191111 firmware.
[Walmart Onn Tablets General] diplomatic:
No, not me. :) The tablet I'm using is not really my personal one, so it's all stock except for TWRP. (Well, I'm not heavy into modding anyway.) But you would have to reinstall Magisk for sure after the update, because the boot partition will be reset.
[Walmart Onn Tablets General] Jiharu Ikumiya:
I apologize for the slow reply, my tablet reboots itself upon selecting fastboot or recovery. I'm assuming its not actually charging either. The screen has been stuck on a charge symbol and keeps going back to that screen.
[Walmart Onn Tablets General] tek3195:
Sounds like you let the battery die. That can be a real pain, I've recovered from it a few times with different methods. All being unorthodoxed of course. [MENTION=4519203]NFSP G35[/MENTION] had written a script to get out of it somewhere way earlier in this thread. I was able to get enough charge one time to flash stock recovery and it charged from there. Another I piggy-backed off of another tablets battery with the backs removed and internal parts dangerously close together(do not recommend). If that's what you've done maybe try leaving it connected to good charging source overnight and see if it will gain enough charge to do anything. If still doing the same then give update and somebody will get you out of it.
[Walmart Onn Tablets General] Jiharu Ikumiya:
Looks like its still dead, can't pass the option menu. Goes back to the green charging symbol. :/
[Walmart Onn Tablets General] tek3195:
Dang, it would be nice to know what state it is in as far as recovery that is on it or where you were as far as flashing when it died. Not being sure of what you have to work with I'm thinking something like flash stock recovery through spft. It should charge in recovery if you boot straight to recovery after flashing. I believe spft will flash w/o battery and I say stock recovery so you will know what you have to work with after. I'm not all that familiar with spft but you would load your scatter and select recovery only to flash single partition I believe. If I'm wrong somebody will correct me in short order. Wait a few minutes and if no better ideas pop up give this a try.
[Walmart Onn Tablets General] NFSP G35:
Looks like you killed the battery. Same state I was in.

Your machine Linux or Windoze?

You can start with this script and modify or rewrite it depending on whether you need bash or bat:

https://xdaforums.com/showthread.php?t=1658084

The general idea is that it reboots constantly into fastboot, and somewhere between all the reboots it picks up just barely enough juice to slightly increase the charge level.

When I modified the script, I made it output the battery voltage each time so I could see that it was actually charging. I don't have access to the laptop with the bash script on it right this minute though.
[Walmart Onn Tablets General] Jiharu Ikumiya:
If I select fastboot the device restarts itself. Would it still work even if I can't get into it?
[Walmart Onn Tablets General] diplomatic:
I had the same thing happen. It lost charge and kept bootlooping whenever the charger was connected. None of the boot menu modes worked. What finally fixed it was connecting it to a PC. I set up SP Flash Tool to do a short readback. I'm not sure if SPFT had anything to do with the fix or if it was simply due to the USB interaction with the computer. But afterwards I plugged it into the wall charger and it started the proper charging animation and I was able to boot it up. It probably just needed to be powered off internally and it wasn't doing that on its own. Funny thing is, that glitch hasn't happened again even when the OS shut down from low battery.
[Walmart Onn Tablets General] DB126:
I have seen this happen with a couple other cheap devices: won't recover from a fully depleated battery; connecting to a PC was the remedy. Thoughts:

- presence of a data connection altered the charging mode; and/or ...

- low current provided by legacy USB2 ports (~0.5A @ 5V) allowed the battery to slowly adsorb a charge and exit the 'critically low voltage' stage

No direct evidence to back either supposition; pure speculation at its best.
[Walmart Onn Tablets General] FanboyStudios:
SP Flash Tools will flash without a battery. I use the Linux version (Solus OS for my distro, should work with most distros), because the Windows 10 version won't even detect this device even with the drivers installed. After flashing you can put the battery back in and try to boot (plugged in of course) if you have a little bit of charge and it may work.
[Walmart Onn Tablets General] Jiharu Ikumiya:
Is there a teardown guide anywhere I should follow, or can I just pop off the back as I see fit?
[Walmart Onn Tablets General] FanboyStudios:
Use a plastic card and gently stick it inside the edge and go around carefully. If you have a microSD card inserted, remove it first! If you don't you may break the microSD slot while removing the front panel. The front panel is held on by plastic clips so be gentle. After you take it apart, disconnect the battery. Then try using SPFT.
[Walmart Onn Tablets General] diplomatic:
[MENTION=2056161]Jiharu Ikumiya[/MENTION], [MENTION=6673664]FanboyStudios[/MENTION], you probably don't need to open the case to try SPFT. The tablet is going into download mode anyway. Any transaction in SPFT will do, successful or not, as long as it shuts down the device at the end.
[Walmart Onn Tablets General] mrmazak:
I know there situations with spflash tool, where an interupted flash, or failed flash makes device get stuck in preloader mode. A low battery can also cause the device to get stuck like this, in flash tool.

In these cases, the solution is often as simple as plugging into wall outlet , sometimes over 24 hr has been needed. Some solutions I read online say you might get faster result by keeping device plugged into wall outlet and wrapping a rubber band around the power button. YMMV.
[Walmart Onn Tablets General] tek3195:
F.Y.I. for everybody. Just looked at output for fastboot --help and seen some new stuff since last time I looked at it. That's been a while so may not be news to anybody but worth looking at.
[Walmart Onn Tablets General] martyfender:
Yes, I saw that myself. I wonder if these commands would disable the boot message that we get that delays boot:

--disable-verity Set the disable-verity flag in the

the vbmeta image being flashed.

--disable-verification Set the disable-verification flag in
[Walmart Onn Tablets General] tek3195:
No, those won't do it. It takes a lot more than that to remove verified boot state and the splash screens that go with it. You're talking about the orange boot state for an unlocked bootloader, but there are more. Green you don't actually see, device just boots. Yellow is from firmware from an outside or untrusted source and Red when the device fails verification. There are some devices that have disabler scripts in a zip that can be flashed and some with modified .img files. If I'm not mistaken the img to be patched or modified varies by device and method used. I know that trying to remove it can result in a hard brick. Found that out twice while attempting to port a disabler to one of my old tabs, which still has that unlocked splash at boot as I decided not to go for third strike.
[Walmart Onn Tablets General] martyfender:
It sounds like it would not be worth the potential risks involved to attempt to get rid of it, as it is not that big of a deal.

Thanks
