Here it is: Stock WiFi images

This is the boot.img and system.img from a stock Wifi xoom!
DO NOT USE TO RE-LOCK YOUR ZOOM
How did I get it? I flashed the tiamat boot to my recovery partition, and booted to it. Then I pulled the pristine boot and system partitions.
The system.img is here: http://www.mediafire.com/file/2fknnmy6nw6i19n/StockWiFiSystem.zip
IMPORTANT: These are unmodified images from my stock xoom. You can't re-oem-lock with them (probably due to the lack of userdata.img). If you do, you run the chance of a brick. (After seeing a complaint of this, I verified it with my own xoom.)
-Jim

Have you verified that once you are rooted, you can flash back this stock image and relock the wifi xoom?
Is this all we need to flash it back to stock? I looked at the official Stock images from Motodev for the 3g version and their zip file contained 4 files: boot.img, recovery.img, system.img, userdata.img. It looks like you extracted boot.img and system.img. Are the other 2 files (recovery.img and userdata.img) needed?

Recovery shouldn't be change, as there is no aftermarket recovery yet. Userdata will create itself on boot with the new system.

If you should need it for some reason, you can get the recovery image from this thread.

ok guys, i tried this this morning.
pushed the stock images and relocked.
now i'm stuck at FAILED TO BOOT LNX 0X0004.
can't get adb OR the computer to recognize the xoom now.
any ideas??
Chris

Has anyone else tried the stock images posted in this thread?

I've reflashed, and booted with them multiple times with no problem. BUT, they don't appear to be enough to do an oem-lock. If you do, you get the "FAILED TO BOOT" error.
-Jim

Since I was the guinea pig and tried this how do i get it running again?
Windows won't recognize that the xoom is pugged in. ADB just says device not found.

Chris. Hopefully an expert with this stuff can answer your question soon. If not, do you have the receipt so you can exchange it at the store? I am sure they will take it.

Sure I have the receipt but REALLY don't want to have to return it if I don't have to.
Hoping this can be fixed. I'll just have to wait it out for a while.

You are braver than I, your problem ids one that CAN be fixed..... but not at the moment that I know of.
What happened is, your device tried to OEM Lock but did not have all of the files. So it did in fact flash you back but is missing 2 other core files that were not pulled.
The only way that I know there is to fix this is to actually flash the SBF file through RSD Lite....... there is one problem though. Motorola has not released this yet.
Honestly, your best bet is to take it back and get a new one because who knows when Moto will get off their thumbs and push some simple files online for everyone to use. :-/
Good luck

RSD would be nice but the xoom doesn't even show up there, not really sure if I CAN sbf back since the computer doesn't even know the xoom is connected.

Well I ran into the same problem with the 3G version and SBF recognized it but nothing else would. Like I said, best bet would be to just take it back and say it is defective and hope they trade it out.... or wait for the complete dump to come out.

Someone did provide the system dump for the wifi version. Not sure if this will help though.
http://forum.xda-developers.com/showthread.php?t=1011484

No, sorry I meant something else.
I meant Moto needs to release the SBF and the Stock everything so developement can actually get kind of started. The ability to root and un-root is great..... when we can un-root.

The system.img supplied by OP corrected my wifi xoom that I'd bjorked by installing the 3G unlock/root on.
In the interim I'd installed the wifi modules. It ran fine but because it considered itself a 3G it wanted to download and install HR166 update which was getting annoying.
I don't think that these imgs will get you back to OEM/locked but that should be available soon enough from MOTO.

Exchanged....I will no longer be a guinea pig. Lol

This is the problem with being home with a broken femur and hip for the past 3 months. I do nothing but get in trouble. ;-)

would you be able to flash 3g abf to xoom and then just reflash everything back to stock once you get it out of the "lock"?

[Beta] Custom ROM (system.img) without unlocked bootloader!!!

FIRST TRY... Edited system.img (KERNEL 2.6.36.3 only!!!)
WARNING: ONLY USE THIS IF YOU HAVE A BACKUP OF YOUR /DEV/BLOCK/MMCBLK0P3 IF YOU DONT HAVE ONE YET, MAKE ONE BY USING THIS:​
IF FROM ADB:
ADB SHELL
SU
IF=/DEV/BLOCK/MMCBLK0P3 OF=/SDCARD/SYSTEM.IMG
IF FROM TERMINAL EMULATOR:
SU
IF=/DEV/BLOCK/MMCBLK0P3 OF=/SDCARD/SYSTEM.IMG
THIS IS A FUNCTIONAL FILE SYSTEM, I AM WORKING ON A CUSTOM ROM WITHOUT HAVING TO HAVE THE BOOTLOADER UNLOCKED.
THE ONLY THING THAT HAS CHANGED ON THIS SYSTEM.IMG IS THE BOOT ANIMATION (INSTEAD OF "ANDROID" IT HAS THE HONEYCOMB BEE) AND THE FONT HAS CHANGED ALSO...
AGAIN, THIS IS JUST A TEST, IT IS THE FULL FILE SYSTEM TO BE USED ON A DAILY BASIS BUT DOES NOT HAVE ANY OPTIMIZED FILES AT THIS TIME.
Alright, now that you have read the warning... download this file here:
LINK = http://www.megaupload.com/?d=1YZSDVZI = LINK
You can then push the file through ADB by typing:
dd if=/sdcard/blk0p3_sys.img of=/dev/block/mmcblk0p3
Post if it worked for you or if it did not, this will help me troubleshoot...
PLEASE MAKE SURE THAT YOU MAKE A BACKUP OF YOUR FILES FIRST!!! THIS FILE IS BASED ON USA MODEL 1.104.05_GEN1 ACER A500. I RECOMMEND TO TRY ONLY IF YOU HAVE HAD TO UNBRICK YOUR TABLET BEFORE. I DONT WANT TO MESS UP YOUR TABLET!!! YOU HAVE BEEN WARNED!!! JEJEJE
Please post if it has worked for you or if it glitched, I am currently in trial and error so... my tablet gets bricked 1-3 times a day because I am testing different things on the system images... hopefully, I can find a way to have root on the image or at least include:
1. File manager
2. ROOT or at least the Gingerbreak.apk already installed.
3. Terminal emulator
4. Custom background upon boot
As stated, it works for me but I have only 1 tablet so if you are daring enough, please dont hessitate to help me in getting this up and running...
I AM NOT A DEVELOPER SO PLEASE BARE WITH ME AS I AM TRYING TO LEARN AS I GO... JEJEJE

props to you!

Applied your image & got the honeybee and very small print. no other changes notes, moving back to previous system image. still can not get updates due to Chinese ROM unbricking, but that will come in time.

cant figure out how to multiquote as clicking the buttons dont do anything.
but just look at "Crsdr37"'s post in general with the imgs and update zip to get back to stock and updates!!!
and to the person who made the IMG keep up the good work. im not gonna flash it and im happy with being stock and getting updates now ;D

Have you figured out how to apply the incremental updates to the img?
I suspect it's just replacing files, I'll look at it when I get to a PC.

Ive been away from my tablet today. I put the post up and went out tonight... jejeje
Thank you guys that tested my image... if it worked for you, THANKS!!! if ou didnt, then let me know what did not work...
THIS IS NOT NOT NOT AN UPDATED IMAGE, IF YOU CHECK THE DESCRIPTION, THIS IS A TEST IMAGE TO GET A CUSTOM ROM OVER TO THE ACER A500... I AM TESTING SO I WILL NOT ANSWER QUESTIONS ABOUT UPDATES... THAT IS FOR MY OTHER POST... SORRY PEOPLE.

Never did. Am back now on the EMEA version and going to wait until someone cracks the code. I have reflashed so much I can do it with my eyes closed.

i am going to try it as well nice thing you guys do

Great
Cheers man, !

So, pulling your system image from /DEV/BLOCK/MMCBLK0P3, then modifying it, then pushing it back works?
Let me try and understand here:
I thought the whole locked bootloader thing checked signatures on the images that are about to be loaded into memory, such as the image in /system.
According to this:
http://www.reddit.com/r/Android/comments/hkbf3/so_you_want_to_know_about_bootloaders_heres_the/
It says:
What does a bootloader do with digital signatures?
It uses them to check any update that passes through it.
So: dd any partition we want to modify, back it up in a safe place, mount the img we get from that, make changes within the img, and dd it back, = all good?
ie: signed bootloaders only have to do with installing update.zips on the sdcard?
Can someone clear this up for me?
Thanks!

Unfortunately, I don't know how to answer that... I have to make my changes through the tab and then pull the system.img. Everytime I make edits externally, my tablet crashes... That's why I'm in testing right now.
sorry guys, I'm not a developer so there are going to be some things I can't answer but if someone is willing to explain it, please do as it is a learning experience for us all... jejeje

If you'd read my question before making an all-caps rude response you'd see that I was asking if you've made any headway into applying the updates, not if you had already done them.

Dude, chill man... You are right, your question does ask about headway for the updates but here are the facts:
You are asking about updates on a BETA Rom that is just in testing...
I took your question to be if the ROM file had the updates (My fault for sure). I was not yelling per say nor trying to be rude but rather making sure that people are aware this is in no way an updated image and should not be treated as such... THIS IS A TEST ROM and since your question was posted within its thread, I took it as if it was directed to the image itself and not toward me and my development...
Look, as stated, im not a developer man, this stuff is a little hard for me to do. I do apologize because I did not answer your question correctly/completely but as far as the comment... Its what I meant. jejeje

Have restored to complete US stock. Had a lot of problems related to SD cards, had to swap them out to avoid errors on the actual update.zip file, but am back to normal. Now if I can just keep my hands off until the 3.1 update comes out, or there is custom ROM...

been installing custom fonts and trying to change some of the system settings from other customized roms directly from the tablet.
Instead of reflashing wouldn't it be easier to just provide the files to push into the tablet? just my 0.02

Yeah, I can provide files for you guys to install but what I was going for was an image that contained everything already setup so you can just flash it over ur old one allowing the "customization" to appear upon install/pushin the file... jejeje

Getting BootManager!

Alright i have been keeping an eye out on a few things and came across BootManager which is a newer app that allows you to easily flash between several roms! Which of course is awesome if you want to try new ones out without reflashing as often. Unfortunately im am not quite as wise in the Android scene yet as i like, new to it with my Acer Iconia as i am, BUT i have been corresponding with the developers for BootManager and they have given me a link so we can submit the Acer Iconia to be added to the devices that can use Bootmanager!
I just don't know how to give them the variables they need!
Could someone that does know how to get the variables needed, (through adb shell or whatever) kindly submit it to them? Here is the link they gave me for submitting new devices, if you do do this, please post it here, so they don't get a bunch of repeat submissions on it, also, so i can keep an eye on the app and get it when they update it accordingly! Thanks very much!
Edit: I can't post links yet, cause i have not posted often enough. Please send me a message and i can give you the link that way! Or just close the space below and use it.
init2winitapps. com/submit_device.html

I'll do it in the morning.

Make damn sure they know they have to run "itsmagic" before/after ANY flash operation (I can never remember which, that's CWM's job!)

I did it too and i sent also a mail to the developers about itsmagic script!

good luck
If you read the information about this program.how it works and the phones that it supports will tell you it will most likely work on our device.THEY SAY WORKS ON PHONES ONLY.and only those WITHOUT LOCKED OR SECURE BOOTLOADERS
But you never know. They might put the efforts to write a new bootloader for this device.the program works by moving the bootloader.well no fifteenth then any other boot manager.
if im wrong and they make it works. I would buy it first.
Goddess erica.

This was posted a while ago and it doesn't appear that the a500 has been added to the supported device list. Has anyone been successful in getting this to work? I want to try it but I'm not sure what issues I might run into if it doesn't work. I need to make sure a Nandroid restore can fix whatever issues might be caused before to try it.

IF i remember right it says on there site this can ONLY WORK WITH UNLOCKED and not encrypted BOOT LOADER DEVICES. I TO Talked to the dev way way long ago..as for this to work they change the boot target in the boot loader to look at there software . then it will boot from there..
kinda like grub to a normal pc.. with the bios being the primary boot . If this makes any sense..
so i think it cant happen.. in the linux thread in our dev area .. someone in the first few pages it talkes about this very app and the flashing the bootloader out.. Dont think they ever figurerd a way around the security..
sorry simple answer is ABSOLUTELY NO WILL NOT WORK
THANKS ACER

I'm confused. My a500 doesn't have a locked boot loader. Thats the reason I got it. I have Thor's recovery loaded on it and I have been able to flash Roms without issue. To boot into recovery I just hold down the volume button and boot the device. I can load custom kernels or pretty much anything else I want. Am I misunderstanding what an unlocked bootloader is?
I had a Razr previously which had a locked bootloader and the only way to flash was to use a bootstrap because it had a locked bootloader. I had loads of problems with it which is why I swapped it out for the Galaxy Nexus when it came out. Both my a500 and Gnex are flashing like champs.
Where there later version of the a500 that had a locked boot loader? I don't think mine does.

[Q] unbricking selfbricked stock A500

My colleague brought his stock A500 to me in a bricked condition last week.
I need a way to restore it. If I try to do a wipe it will say bootloader error if i try the recovery the droid falls down with the red sign with the exclamation mark.
This tablet has never been rooted, my colleague is not in to such things, it's lived its life with ordinary acer otas and the occational very young human (5 year old) trial wich it has survived.
He has installed all the OTAs he ever got on the tablet and this is in Sweden so it would probably be a 4.0.3 acer stock on it now.
I'm guessing it has died during a OTA or something. if i turn it on it will sit at the acer logo indefinitly.
I Bricked my A500 during a rooting atempt resulting in me needed to flash a stock rom to get it working again, but i cant find the thread i read to un-brick my A500.
Please Help!

we're assuming the tab is full stock and currently on ICS...
and we're assuming he never tried to 'fix' his tab by flashing one thing or another...
the bootloader error worries me...what exactly does it say...
Yes the wipes are really important!! and not being able to use the button method to do so is concerning...
what happens with the Over The Air (OTA) updates is its just that...an update...it leaves all your settings/data intact. When you OTA from one build to another, like Gingerbread 3.0 to Honeycomb 3.1/2 and then to ICS 4.0 - you drag all your apps and settings with you and of course some things that work with 3.2 will not work under ICS....fjor instance, lots of folk had trouble with wifi disconnects, once they got to ICS - or they had apps force closing and other 'glitches'. This is why everyone tells you to do the wipes - as this fixes these things! In the case of stock ICS my gmail would f/c all the time no matter how many times I wiped/formatted....So for a smooth running tab - flash a custom rom!!!!!!
But getting back to you...
From that link i gave you...download the 3.1_Full.zip....its decrypted so just extract it and get the "update.zip" from it..
This "update.zip" is not an incremental "update" but the full stock rom....
once installed you'll be on GB you will need to root it with iconia root and then use acer recovery installer to flash cwm....(get these from the playstore)
do a backup or adb devices so you can get your CPUID....this is important...if anything goes wrong at any stage this is the only thing that will get you unbricked....see the cpuid link in my sig for more on this, please take the time to read it, even if it doesnt make much sense to you, read it anyway....
AFTER you have retrieved your cpuid, you can nvflash the patched bootloader/recovery pkg which means you are able to flash ICS/JB custom roms
they cannot be flashed via cwm like normal...you must use nvFlash to do it....
OR
take the OTA route to ICS...this takes a bit of time...I did it last week and it was a good 6-7 hours to go from GB to ICS
there are pre-rooted stock roms if you wanna stay stock see civato's stock rom thread for that here http://forum.xda-developers.com/showthread.php?t=1633907
official stock rom list by blackthund3r are here http://forum.xda-developers.com/showthread.php?t=1816560
civs guide to flashing the unlocked bootloader here http://forum.xda-developers.com/showthread.php?t=1622425

I am in a similar situation. Push the power button and it goes to a screen with white acer on black and stays there. Totally stock ICS, no root. I tried the update.zip thing and after automatically rebooting it says "Boot verified failed...". I don't have my cpuid, or have installed previously CWM or anything like that. I can get into APX mode. This guy here: http://forum.xda-developers.com/showthread.php?t=1751978 could only get into APX with no cpuid as well, but i don't understand all of the ubuntuu and command line stuff. I would love for someone to be able to walk a dummy like me through this mess. Thanks for any help.

if u got boot verified fail error you need nvFlash to repair that....as u know, with nvflash you need yr cpuid....wot about usbdeview? if you've never plugged yr tab into yr PC - then it won't work and the ONLY other way is Linux....
might be best to start yr own thread with a descriptive title, not just a help I'm bricked no uid, thread there are hundreds of those....the more effort u put into the title the more likely you will attract the attention of someone who can actually help...and remember you just don't need a bit of help but a blow by blow description of what to do and how....this will be very time consuming....at the very least get ubuntu installed, maybe just try a few things, anything to show you are capable of at least giving it a go yourself..
there are others who would like 2 know how to do this as well...having a specific thread of its own would be great
good luck

yup...usbdeview.zip see the bottom of the OP in the cpuid guide in my sig

Thanks alot for your help. I used usbdeview and got my cpuid. Now I should use nvflash? Know where a good step by step is for that one?

"To install one of these roms you will need a custom recovery and to get that you must flash the patched bootloader FIRSt - once its patched you can install a recovery any old way you like"
Looking at that guide, would you please tell me what a custom recovery is and how to get one? Btw, I don't plan to do a custom ROM yet, I just want to get the damn thing working first. Was thinking of using the HC EUUs from the firmware files list. However there are two files, a .rar and a .exe listed. Which do i use?

The .rar EUU is for an A500, the .exe is for the A501, which do you have?

I've got the a500. However, I decided to go with a custom ICS rom after all. I managed to put a new bootloader and custom recovery on using the a500apx flash tool. That part went fine. I flashed this rom:
Acer_AV041_A500_1.054.00_WW_GEN1-FULL-ROOT (original odex)
and that appeared to go well according to twrp, but after rebooting, it just shows the bootloader again and stops there. Not sure what i did wrong.
I renamed the rom update.zip. Should i not have done that?

well congrats for getting thru the flash process with no probs!!!
as far as renaming to update.zip that was not such a good move...hopefully things havent been screwed up too much
just go back into recovery and do a FULL wipe/format
then to flash use the option "install from zip file" not sure where that is in TWRP but it will have one

Okay. I will reflash the rom after completely wiping again. Thanks.
On a different note, why do roms require particular bootloaders?
Also different, how do you like your SGS3? If i can manage to fix this thing, perhaps I'll root my phone...

The stock ICS BL is encrypted - more or less - the only way to 'flash' a recovery or rom is to have the "key" that "unlocks" - it more or less - if you dont use the right key then the OS will not boot - the 'key' is based on your cpuid which is why everyone is forever telling you to save it somewhere safe....

I have a case for it now, and its gr8 - I havent installed a rom on it yet...the forums over there are jampacked and I have no idea what I'm doing, lol - its the first android device I've had that I've left stock for so long...but it does what I want...the camera is awesome -burst mode is the bomb - BUT do I think it was worth the money???? Still on the fence about that one.....

Ouch. Sorry to read about running over your phone. That would kill me. I really like my SGS3. I think I'll look into rooting it just to be able to back it up and get rid of the bloatware. I did that on my Captivate and prior to today, thats all I've ever done modding wise to an android device.
So, I managed to get my tab up and running again. Yay! I reflashed the rom w/out changing the name and worked like a charm. Now If only I knew why this happened in the first place... Thanks for all your help.

yeh sometimes happens with the tab for some reason - thank your lucky stars it didn't get stuck in apx mode...if that happens its normally a hardware fault so theres not alot u can do...I'm just pleased you got sorted without too much drama and it was as easy as reflashing the zip....so now you have the v8 BL - you're gold!!!

When you OTA from one build to another, like Gingerbread 3.0 to Honeycomb 3.1/2 and then to ICS 4.0 - you drag all your apps and settings with you and of course some things that work with 3.2 will not work under ICS....fjor instance, lots of folk had trouble with wifi disconnects, once they got to ICS - or they had apps force closing and other 'glitches'. This is why everyone tells you to do the wipes - as this fixes these things! In the case of stock ICS my gmail would f/c all the time no matter how many times I wiped/formatted....So for a smooth running tab - flash a custom rom!!!!!!
But getting back to you...
From that link i gave you...download the 3.1_Full.zip....its decrypted so just extract it and get the "update.zip" from it..
This "update.zip" is not an incremental "update" but the full stock rom....
once installed you'll be on GB you will need to root it with iconia root and then use acer recovery installer to flash cwm....(get these from the playstore)
do a backup or adb devices so you can get your CPUID....this is important...if anything goes wrong at any stage this is the only thing that will get you unbricked....see the cpuid link in my sig for more on this, please take the time to read it, even if it doesnt make much sense to you, read it anyway....
AFTER you have retrieved your cpuid, you can nvflash the patched bootloader/recovery pkg which means you are able to flash ICS/JB custom roms
they cannot be flashed via cwm like normal...you must use nvFlash to do it....
OR
take the OTA route to ICS...this takes a bit of time...I did it last week and it was a good 6-7 hours to go from GB to ICS
there are pre-rooted stock roms if you wanna stay stock see civato's stock rom thread for that here http://forum.xda-developers.com/showthread.php?t=1633907

I googled your error - the consensus from what I read is a corrupt OS due to running OTA updates...
Some had luck with rebooting. Others had to send it to Acer.
Did you run the update.zip? so what happens when you run the update.zip
Are you able to get into "apx mode"? If you can, hook up to your PC and see if your tab is recognised as an "apx device" - check "Hardware, Printers in win7"
Thats all I can suggest atm - if your tab does get into apx mode OK then you can find your cpuid by running Linux -
Maybe ask the guy if he's ever had the tab hooked up to his PC like to transfer files and stuff - get him to download "USBdeview" to his PC -
this will show every single device thats ever been connected to the PC and it will show the "cpuid"...
Even if we do get the uid theres no guarantee it will fix the bootloader error - but we may as well explore all the options we can....

USBDeview will only work when you have previously plugged your tab into the PC WHILE you were running HC Rom and BL
1. If you haven't plugged your tab into this pc before, do so now, before you run the program. HC ROM/BL ONLY
1a. Run the exe and you will be presented with a window of all the USB devices you have ever plugged into your computer.
2. Click on "VendorID" column along the top to sort them
3. Look for the number "0502" under Vendor ID AND "3325" Product ID
4. In the serial number column will be a 15-digit number this is your device ID.
5. Write the number down and put a 0 in front of it and now you have your CPU ID!!!

Onn 7" Model 100026191 TWRP Development

Alrighty... So I'm in the weeds here after going through three variants of the Samsung JPop (Which have bootloaders locked up like Fort Knox) and decided today to break down and dish out $59 for this bargain device. First thing I did upon getting it home was fastbooting it, and was able to unlock the bootloader with no issue. (So easy, a caveman could do it)
I've read just about every thread in here and though there seems to be TWRP support for quite a few models of the Onn tablets, I didn't see this one in here. Right now I have a throwaway laptop which is installing ubuntu for building TWRP for this device. Now, I have NEVER built TWRP. But I have plenty of free time, ambition, and am willing to learn. I have the basic guide to building TWRP open elsewhere. I will take whatever help I can get on doing this, big or small. Building a basic TWRP image should be easy enough, but the guides don't really go into device specific details (as expected), so this is where I could use some veteran help.
Device Specs:
Model: 100026191
Out-of-the-box Android Version: 11
Display: 7" 1024 x 600 Resolution
Processor: 2.0 GHz Quad-core CPU
RAM: 2GB
Cameras: 2MP front & back
USB: Type-C

Ubuntu just finished, and I am getting the build environment ready as we speak. Will keep this thread updated with progress and hickups that may occur along the way. Wish this noob some luck!!!!

Alrighty, so here's what I've been able to come up with as far as more detailed system information. Sorry for the late post, had trouble getting wifi working on ubuntu but got it going.
I suspected a MediaTek CPU and was eager to do a readback with SP Flash Tool, but as you can tell from the provided screenshots, it's actually a Cortex-A53 CPU. my goal here is to some how pull my stock recovery out of here. I thought about dd'ing it but someone in another thread advised against it. Does Onn have stock firmwares hidden away in the internet somewhere? Or is there another tool I can use to pull recovery?

Good evening guys and gals. New day, new opportunity. So i'm still stuck at pulling off boot and recovery from this tablet. I used
Code:
/adb shell cat /proc/mtd
to no avail. Permission denied just like with dd.
Today, I got the MTK droid tool and hooked the tablet to it and got these results. Still no scatter file, still no progress on pulling these partitions. (I apologize for my dumbness yesterday, this device is in fact MediaTek)

Alright. Eighty of you have clicked in this thread, zero of you show any motivation to do anything to contribute. You guys must hate this tablet because I went through this entire board, and each thread that even mentioned this model were left with no response. I just want the boot and recovery partitions off of the stock tablet. I am willing to do the rest. I said before, I'd take any help I could get but since this device is "so" insignificant, I'm not trying anything else on it.
I don't know if you guys dodge this device because it's Android 11, or what. But the least you veterans could do is either tell us it's not going to happen (given that you tried), or give us some other ideas we could try. Hell I'll paypal you enough for you to have the device in your hands in order to help. But that's where I stand. Moderator can lock this thread if he wishes. There's nothing else I can do for this device at the moment.

guess i'll return it to walmart
was hoping to root it easily with twrp
just gonna go grab the 8' if this is how it ended for the 7'
thanks for the help though!

I need a firmware for the 100026191

I have the boot and recovery images if you want them.
I unfortunately accidentally deleted the original boot image, but I have a magisk patched image still present.
I can walk you through the process of extracting the original if you would prefer that, it's quite simple, I just don't feel like buying a second Onn tablet at the moment.

Just note that if you want to extract the original boot image, do NOT flash the Magisk image, it will permanently erase the original boot image. There is another way, I can walk you through it.

I oicked up one of the gen3 tablets. Do you think your way of pulling the boot image would work on it?

My way of pulling the images should work on any Android device that ships Android 8.0+, however if you got it brand new, don't update it.

Factory reset it if it downloaded an update, then disable OTA updates before enabling Wi-Fi.
You can run `adb logcat` while the update is downloading to find out where to download the OTA, and dump the boot partition from that.
From there, if you install Magisk, you can dump the recovery partition with `adb shell`.

Ok I will have to reset it then go from there. Do you have a guide on how to pull the image?

When doing first time setup, don't connect to Wi-Fi.
Enable Developer Settings
Disable OTA Updates
Enable USB Debugging
Connect to Wi-Fi
Connect the device to your computer
Run `adb logcat > ota.txt`
Reenable OTA Updates
Go to Software Updates and start downloading the Android 12 update (If it's not the Android 12 update, disable OTA updates again after this one finishes installing, then try logcat again after rebooting)
Search for a link that looks like `https://android.googleapis.com/packages/ota-api/package/827ee737174e0e8f761bcaeb12738221a924c810.zip` in the logcat.
Put the update link in your browser, and download the zip file.
Extract the zip file
There's your boot.img, very conveniently.
The update link I have provided is for the 100074181, the 3rd gen Onn 7, if you happen to have that one then go ahead and just use my link.
Though update to Android 12 before actually using that boot.img with Magisk, it won't work with Android 11.

After you're done with that, and you're rooted.
`adb shell`
`su`
`dd if=/dev/block/by-name/recovery of=/storage/emulated/0/recovery.img`
Then connect your tablet to your PC and enable file transfer in USB settings, then just pull recovery.img out of your tablet and you have the recovery image.

Update to Android 12 before using Magisk, just in case.

I will look for it. Saved it to a USB drive and of course it decided to be stupid and it is repairing now. Slow going but as soon as it gets done I will look to see if it survived and if so I will get it uploaded.
