There is an a new cve for all qc devices.

Maybe there will be something made if it! Since it allows full root access. Image every qc phone instantly being rootable!

Here is what i said before

:cyclops: missed an "a" but u get the point :highfive: Plus i think jailbreaking Amazon devices was pretty popular. Enough off topic for me though.

How do I reset my rooted Onn tablet to the newest firmware?
[Walmart Onn Tablets General] DB126:
You can't - at least not without considerable effort and a measure of risk. Stay on whatever build you're on now and be thankful each time the device boots without drama.
[Walmart Onn Tablets General] martyfender:
I have an Onn 8 from February 28th, 2019. I have flashed the stock backup, 05162019, to it many times without issue by using spflash tools on Windows. I tried, in the past to do it from Linux Mint Mate using that version of spflash, but it always failed.

https://www.nathanbar.net/files/android/ONA19TB002/stock_ONA19TB002_20190516.zip.

I used this excellent guide to flash it:

https://xdaforums.com/showpost.php?p=80574967&postcount=192

Of course, this is truly stock, with the bootloader locked. You will have to setup Android, unlock the bootloader, reflash twrp and Magisk and reinstall all of your apps, etc.

Internal storage is erased, so I am guessing that if you have a twrp backup saved on your external SD card, you could then restore it after the above steps. I however, have not done that, in favor of doing a fresh install. It appears, though, that twrp does not backup internal storage.
[Walmart Onn Tablets General] martyfender:
I just bought the latest Onn 8 which upon the long, download, installed a system update with a security patch of about March 5th. I then installed twrp and Magisk Canary, the latest. The boot animation screen has been revised.

I did not test the temp root to see if it works with this security patch, or not. Swipe sideways is back, compared to my older tablet, in which I have to swipe up to remove recent apps.
[Walmart Onn Tablets General] martyfender:
[MENTION=8491352]tek3195[/MENTION] [MENTION=8132642]diplomatic[/MENTION] On the newer Onn 8 I bought, I checked all partition options except recovery and backed it up in TWRP to my external SD card. Can I flash this newer backup to my older, original Onn 8, with the older model number, to have the latest Android security patch on it? Or am I asking for trouble doing this? I understand that the hardware is the same on the newer model number.

Thanks
[Walmart Onn Tablets General] diplomatic:
[MENTION=8126387]martyfender[/MENTION], you're talking about transferring the FW from the Pro model (Android 10) to the original Onn 8"? No way. I think it was mentioned several times that the HW is different and not even close. The chip on the Pro is MT6762.
[Walmart Onn Tablets General] martyfender:
No, it is not the new model, but newer version of Onn 8 with Android 9 and the only change other than newer security patches is the model number is changed to 100005207 from the earlier Onn ONA19TB002. That is how they show in AIDA64. Other than that hardware appears to be the same. I am using your latest TWRP on it.

Fingerprint: onn/100005207/5207:9/PPR1.180610.11/1584007030:user/release-keys .

Re-read what I wrote, it is not the new Android 10 pro tablet.
[Walmart Onn Tablets General] DB126:
Err... dissatisfied with the currently loaded firmware because... ??

Security patches, while relevant, are not a BFD on android devices. Watch where you surf and don't download sketchy files. Behavior is 98% of the problem and 100% of the solution.
[Walmart Onn Tablets General] martyfender:
Thanks, I fully realize that. My behaviour is very good in that regard.
[Walmart Onn Tablets General] diplomatic:
Oh, then I'm not sure. It might work. I thought the TB002 already had a recent security patch. (That's why I misunderstood your question.) Normally, when you want to transfer a FW to another device, it's not just a question HW compatibility. There's also HW encryption keys to consider. But these tablets seem to not have secure boot enabled, so it might be possible. I wouldn't say it's worth doing though. Doesn't your older tablet have an update from April? Or is it just stuck at downloading it?

Yes... and also true for PCs. Security software doesn't really make much difference when you watch what you're doing.
[Walmart Onn Tablets General] Pix12:
So I've tried to flash the November stock, and it seems to not be compatible with my white box 8", seems that the BL is too small for the download DA. The stock May one is working. Did the November stock images get ripped from a white box model, or was it from the yellow box "surf onn." model?
[Walmart Onn Tablets General] martyfender:
I have a white box model and I have successfully flashed the November update to it several times with spflashtool in Window 7 with no problems. My second one is the yellow box model, and I have not tried to flash these updates to it, since it is performing flawlessly. By the way, I believe the November backup is from the white box model.

I used these instructions to flash it:

Just simply connecting to PC use "adb reboot bootloader" once in fastboot mode use "fastboot flashing unlock" and follow on-screen prompts to unlock bootloader?
[Walmart Onn Tablets General] aaronm32:
Has anyone figured out how to remove the Walmart nav button from the Onn 8" Tablet Pro model (100003561)? I just picked up one and didn't even think about it when it asked me to update to Android 10 June 5, 2020 build QP1A.190711.020.

It looks like MTK-SU is blocked. When I tried fastboot the tablet reboots with "=> FASTBOOT mode..." on the screen, but it is unresponsive and I cannot send it any fastboot commands or connect to it. At this point, I have to hold down the power button to reboot it.

All I want to do is remove the Walmart nav button. I tried some apps, but none of them seem to work 100%. Thanks!

---------- Post added at 03:43 PM ---------- Previous post was at 02:47 PM ----------

EDIT: I figured out how to get rid of the annoying Walmart navigation button in Android 10. Just had to go into settings>System>Gestures and change the System navigation from 3 button to 2 button navigation.
[Walmart Onn Tablets General] tek3195:
Yeah, that's it. As long as you have correct drivers installed. If using windows it installs some oddball drivers that don't work with adb and fastboot. Install MTK drivers if so.
[Walmart Onn Tablets General] tek3195:
If adb works and not fastboot it's most likely drivers. Check device manager to see what is installed. Or better yet, use Linux. The wal-mart button can be a ***** anymore. I flashed my first gen ONA19TB002 back to stock to try something and after update I cant get walmart button off without losing recents button. Now <settings put secure sysui_nav_bar 'space[1.5WC],back;home;recents,space[1.5WC]'> leaves it with back and home only.

If you would please be so kind as to explain this more in-depth for this thread came up when I was searching out fpr on this same kind of tablet with detachable keyboard? I am new to learning android sorry if I am being a bother.
[Walmart Onn Tablets General] codyw1996:
Okay, so the folder in the Google drive in the OP is empty.

Does anyone have the patched_boot.img for a TBBVNC100005207?

I think there are two versions of the Onn 8 inch tablet, I guess i have the newer one?

It's running android 9.
[Walmart Onn Tablets General] tek3195:
Yeah google trashed over half of my files, I need to remove those links. What do you need patched.img for? If wanting it for root access just flash twrp and install magisk from recovery.
[Walmart Onn Tablets General] martyfender:
Hello everyone. I have been away from this thread for a while. I am an electronic associate at an Indianapolis Indiana store. I was on vacation last week and came back to work to find that a new version of the onn 8 tablet is available in our store. It, as I remember, from reading the box, is called the gen 2 onn 8 tablet. Since there is no mention of it on walmart.com, I am going here on my memory: It has a faster processor, 32g of internal storage, Android 10 Go and the desktop looks very similar to the previous tablet version. I wish I had taken a screenshot of the specs on the box, since, as I mentioned earlier, I do not see it listed yet on walmart.com. I am speculating that it is manufactured by the other company that did the pro version of the tablet. I also saw, in my limited time to look while working that there are new 7 and 10 inch models with similar specs. The only other box I had time to look at was the 7 inch and it had much better specs than the original, poor, 7 version. It was a surprise for me at this time of year, as I have usually only seen new models launched in the spring to summer months in the years I have worked here. I wish I had more insider info on these new releases, but I do not. I am doubtful that these would be able to be easily rooted since they have Android 10 Go.

If anyone has anymore info on these new devices, please post here, or maybe even better, a new thread could be started for this new model. [MENTION=8491352]tek3195[/MENTION] [MENTION=4519203]NFSP G35[/MENTION] [MENTION=8132642]diplomatic[/MENTION]
[Walmart Onn Tablets General] nannycrick:
Hi guys. Been away for a while. Bought an Onn 8.0 running Pie, and having trouble unlocking bootloader. I run W10 x64 on my Dell AIO, installed ADB systemwide, disabled driver signing, hooked up the Onn in fastboot mode, typed in - adb devices to be sure I had connection, typed in the CMD command to unlock, and it just keeps saying..."waiting for device".

Where am I going wrong?

I'm not necessarily a noob, but this thing has stumped me!
[Walmart Onn Tablets General] nannycrick:
*UPDATE*

Got this baby rooted...AFTER I managed to get the latest Mediatek driver installed.

Now we have TWRP, Magisk, and all the other goodies installed to fix this tablet up, I'm good to go.

Thanks for everyone's hard work on this cheapo!
[Walmart Onn Tablets General] Crumplet:
What kernel manager are you using for modifying?

Or are you using init.d manager in stead?
[Walmart Onn Tablets General] nannycrick:
I use Magisk Manager (latest version). You have to flash magisk zip after TWRP recovery flash. Then, after reboot, download & install Magisk Manager as a regular app. Works great. Both the apk and the flashed zip work together to manage the kernel.

This one with MT8168

Hi guys,

I had the new model onn8’’ Gen2, Build 100011885_20200703, Android 10.

If I understand correctly the OP with mtk-su by @ diplomatic will not work but CaffeinePizza's post #192 may.

Without windows at home I followed @Spatry #286

fastboot flashing unlock
fastboot --disable-verification flash vbmeta vbmeta.img
fastboot erase system

Will it work for the surf pro though is the real question
[Walmart Onn Tablets General] Tofor:
So far... on the 8in pro this method does not appear to work using either --disable-verity or disable-verification. It gives the code "flashing vbmeta with the offset 0" And still goes into a bootloop. I havent tried it yet but i think it may work if that command is used with all 3 vbmeta img files and not only the primary one. I will try this after i get off work and I'll post results.
[Walmart Onn Tablets General] zmance:

[Walmart Onn Tablets General] Tofor:
Okay. You definitely want to check this firmware out and make sure it's for the 3561 model. I honestly do not remember having this and I had the 8in surf pro tablet. Not just the pro one. But from the name It does not say surf in it. Only pro so it should be the right one based on the name only. Just do not trust that and make sure. I am not responsible for any brick bricking

Need Help

how do i know if the adb is installed correctly? ive been banging me head all day and cant seem to figure this out and i dont see anyone else having this issue
[Walmart Onn Tablets General] NFSP G35:
If you can use ADB shell, it's fine. Sounds like the problem is only fastboot. Could be driver related, or the fastboot executable.

To be honest, Linux is so much better at interfacing with Android that anytime I want to do anything ADB or fastboot related I just boot up in Ubuntu instead of Windows 10. Maybe try making a bootable Linux thumb drive. Prob less time consuming than banging your head against the wall all day
[Walmart Onn Tablets General] St0n3r4202019:
i think all i need are the device usb drivers used for adb when the onn 10 is in fastboot mode it doesnt show up but it does show up when in adb i dont understand ive tried the google usb drivers ive tried the mtk drivers and the mediateck drivers please help thanks
[Walmart Onn Tablets General] NFSP G35:
Yeah, I only mess with ADB and fastboot through Linux, I've never even tried with Windows 10... Maybe OP can help?
[Walmart Onn Tablets General] tek3195:
It sounds like you may need to update your platform tools. If you look at 15 sec installer thread you will see where [MENTION=5988026]Redline[/MENTION] mirrored newer version. I use Linux so I'm not sure. I say update because just as the commands have been updated so too should be the tools ie "fastboot flashing unlock". Only thing that comes to mind plus I can't remember when or where but read someone else had similar issue and that was the solution there if I'm not mistaken. Newer stuff can't hurt and it 's worth a try. I think.

fastboot -i 0x0e8d devices

The old versions of both ADB and Fastboot relied on a hard-wired list of USB vendor ids.

If you have an old version of Fastboot you need to add the vendor id of Mediatek, 0x0e8d

The "-i 0x0e8d" clause has to be added for any Fastboot command.

The Onn 8 is a bit strange since the ADB interface and the Fastboot interface both use the same USB VID/PID, 0e8d/201c.

The driver for either of these is the generic WinUsb driver which simply gives you a pair of bulk endpoints.

So you could see "ADB interface" in Device Manager (devmgmt.msc) and you have Fastboot working correctly.

Or, the other way around, see "Bootloader interface" and have ADB working correctly.
[Walmart Onn Tablets General] Renate:

Is there any news on getting TWRP working on the 8 inch tablets?
[Walmart Onn Tablets General] tyderian:
I had the same problem even though I updated platform-tools first. I went into Device Manager and it showed a generic "Android device." I had the Google ADB drivers installed already--other devices work fine and adb on this device worked, just not fastboot. I used Windows' built-in tool to search for an updated driver anyway, and that worked.

Maybe there was an update to the driver? SDK Manager didn't show one.
[Walmart Onn Tablets General] Mycroftski:
Not to be a pain, but can someone please help explain how to root this and unlock the bootloader. my goal is to put Kal Linux and Android Pie dual boot. if possible that is.

[Walmart Onn Tablets General] NFSP G35:
^ not to be a pain... But everything you asked for is covered in the first post. Granted it's not spoon fed in a step by step way, but it's all there.

Basics are:

- Unlock bootloader via devtools and fastboot command

- Use mtk-su to pull the boot image

- Use Magisk Manager to patch the boot image

- apply patched image with fastboot

- profit
[Walmart Onn Tablets General] beefy1986:
If anyone wants to throw a cleaner ROM on this device (after unlocking the BL), I found that the GSI image named "system-arm64-ab-gapps-su.img.xz" from this page worked well: https://github.com/phhusson/treble_experimentations/releases/tag/v119

Obviously (by the name), this rom is pre-rooted and contains gapps, so you may want to choose a different one from that release page.
[Walmart Onn Tablets General] tek3195:
I would like to see some screenshots or logs to qualify your statement. These tablets are A-ONLY and that is an AB-ROM. There are different designations by [MENTION=1915408]phhusson[/MENTION] for a reason. According to the FAQ on Github "What does "AB" and "A-only" mean? Should I use an "AB" GSI or an "A-only" GSI?

phh has provided "AB" and "A-only" GSIs. The terms "AB" and "A-only" (or just "A") refer to the partition style used by a device.

The AB partition style was introduced in Android N to support seamless OTA updates.

A-only, A, or non-AB refers to the legacy partition style.

If you have an AB device, then you must flash it with an AB GSI. If you have an A-only device, then you must flash it with an A-only GSI. The two types of system images are not compatible with each other."

here is link to full page

https://github.com/phhusson/treble_...-mean-should-i-use-an-ab-gsi-or-an-a-only-gsi

Put something up to verify it if it worked for you. If not, then please do not litter XDA with false information as there are some who believe what they read here to be true simply because it came from an xda thread. Don't tarnish that.
[Walmart Onn Tablets General] OgremustCrush:
I don't claim to have actually tried it (ordered a refurb tablet that hasn't arrived yet,) but on the on the supported devices page phhusson GitHub it does say:

Why should I use GSI for A/B devices to some A-only devices? : On Android 9, Google changed the requirements and all devices shipped with Android 9 must use "system-as-root". Before this change, only A/B devices were system-as-root and GSI name was separated by A-only and A/B. For this historical reasons, you have to use GSI for A/B on the devices shipped with Android 9+.

Since this tablet ships with Android 9, it seems like A/B would be the correct choice.
[Walmart Onn Tablets General] beefy1986:
I was going to post the note about using AB GSIs on A devices which shipped with Android 9+, but @OgremustCrush beat me to it. I'll be happy to post whatever log you like; which log (or part of a log) would satisfy you that this GSI booted successfully on this device?
[Walmart Onn Tablets General] tek3195:
I don't know exactly what would show it, but your response does it a good bit of justice. Looking back at my post, it wasn't meant to sound the way it probably does. This device is system_as_root but all of the treble compat checking apps came back with A only and no support for AB or seamless updates. That was where the skepticism of it working came in on my part. If it works, cool, glad to hear it. Although I can't try it just yet. Mine is a sad brick for the time being. Unless someone has a scatter based backup to flash through SPFT or MiracleBox mine's toast with no fastboot.
