hey guys i flashed the stock without keyboard on my 10.1 but the screen stays black and no recovery, nothing
[Walmart Onn Tablets General] lexcin:
onn surf 7

hey hello, I've been trying to flash majisk on the 7 inch tablet, and spflash tool seems to turn it down,

ok I've tried to flash stock got two times to download

with red download bar showing, using an old p.c, spflash tool crashes before the green check, about a minute...holding both the volume up and down buttons at the same time

the question would be does the 7inch root or can a stock image be flashed

also fastboot says patched boot accepted, after reboot no root

anyone ??
[Walmart Onn Tablets General] lexcin:
root onn surf 7

sorry I missed thread, so fastboot patch to recovery

, do you know the button combination

I have no go charge battery...so far ? thanks

Options to restore a tablet?

ok [MENTION=10059830]Viva La Android[/MENTION] I have been looking through your post all day, I bought one of these thiking it would be something at least useable to study on, but since I got it, it has been doing bootloops. I think someone tried to flash it or something, but all I can get out of it is a bootloop. I have tried flashing via SPFT, and am downloading anothe rfirnware right now. I can boot into recovery, and at one point one of the files I had even had it with TWRP as a recovery. At this point, I would just like to use it to give it to my son, so, if you have any ideas on how I can save this you would be a lifesaver! I have already thrown money at this stupid tablet, but am not afraid to buy you a beer if you can point me in the right direction!

onn tablet 7

from what I saw, was a rom with blocked root

and BusyBox like you say other developer s

might design a rooted rom that could be flashed to the tablet, if it was possible, if the tablet s features are patched, I don't really see custom recovery working here

but mine seemed to accept stock images rather easily

just put your stock.img in spflash tool and eat it dude :crying:
[Walmart Onn Tablets General] tek3195:
7" can be rooted. I posted a thread with instructions last year. Without looking back to it I believe I used fastboot to flash instead of spft. Also you have to set Magisk manager correctly in advaned settings and patch recovery.img. I didn't keep the tablet, really only bought it to root, post instructions and return. But it is definately rootable.
[Walmart Onn Tablets General] Viva La Android R.I.P.:
Sure. I don't mind trying to help. Just so I am completely certain, do you have the 100005208 model? Also, could you please state exactly how your device ended up in a boot looping state. Did you attempt rooting or modifying it, or was it boot looping as soon as you got it?
[Walmart Onn Tablets General] jdelfin85:
No mods, bootlooped from day one (it was a refurb via a certain outlet and chain store) it is the 10.1 w/o keyboard, ends in 003 (sorry but I'm on my phone) I have access to fastboot and recovery, and soft. Whatcha got?
[Walmart Onn Tablets General] Viva La Android R.I.P.:
Run the command:

fastboot getvar all

List the output for me so I can fully identify your model and bootloader status. Thanks. Sounds like you have the ONA19TB003 but I need to be certain. In fact I think it's safe to assume that yours is the TB003 model. You should be able to successfully fastboot flash your device back to life. Do you have the Minimal ADB & Fastboot tools installed on your PC or laptop? If so I'll list the instructions for restoration using fastboot. If you don't have the tools installed, I'll get you a link for the latest version.
[Walmart Onn Tablets General] tek3195:
For 003 there is firmware and flashtool here https://www.nathanbar.net/files/android/

I used his 002 several times and he has a guide for them somewhere. You can search [MENTION=9936108]CaffeinePizza[/MENTION] and find it. His guide worked on 002 flawlessly so 003 should work the same if you download spft from his server to have correct version. You can also flash images individually via fastboot.
[Walmart Onn Tablets General] Viva La Android R.I.P.:
[MENTION=4002472]jdelfin85[/MENTION], once you have the latest Minimal ADB & Fastboot tools installed and set up, download these 003 images from the beginning of the thread: system.img, boot.img, recovery.img, vendor.img and vbmeta.img. Place these images in your ADB & Fastboot directory, connect your device to your PC/,laptop, open a command window in your ADB/fastboot path, and execute:

fastboot devices

If you're properly synced, the command window will return an alphanumeric string synonymous with your device's serial number. Now, execute the following fastboot commands, preferably in this order:

fastboot oem fb_mode_set

fastboot flash vbmeta vbmeta.img

fastboot flash boot boot.img

fastboot flash recovery recovery.img

fastboot flash vendor vendor.img

fastboot erase system

fastboot flash system system.img

fastboot erase userdata

fastboot oem fb_mode_clear

fastboot reboot

As long as you are using the most current Minimal ADB & Fastboot tools, version 1.4.3, the system image will be converted to a series of sparsechunk files and systematically flashed to your device (you don't have to do anything except execute the above commands -- fastboot will do the rest). Initially, fastboot may indicate a header size notification, but just be patient and allow the process to complete. It can take 3 to 4 minutes for system.img to fully flash.

This should get you up and running. If you want root after unblocking your device, there are some great guides here in the device forums.
[Walmart Onn Tablets General] tek3195:
Need to check oem unlocking in developer options. If you cant get in to menu then will have to use spft.

I don't know if ultraflash works with locked bootloader or not, it allows flashing protected partitions and bulk transfers. Just don't know about in locked state. To enable it you use "fastboot oem ULTRAFLASH_en" then "fastboot oem ultraflash:system" then "fastboot flash system system.img" of course without quotes and sub your img in place of system. Ultraflash is a manufacturer tool that is intended to be removed but joyar left it in the first gen Onn tablets. It will flash system without converting to sparse chunks and allows bootloader and other protected partitions to be flashed with fastboot.It can actually be quite dangerous if you don't pay attention to what your flashing.
[Walmart Onn Tablets General] jdelfin85:
I am going to try and get it to spft one mroe time, see if it will let me go to developer options. It had booted into the system once, and was a bit stable but after that I could not get back to the main android system. Ultraflash command did not work, so unfortunately with a locked bootloader I think I may be borked...

---------- Post added at 10:14 AM ---------- Previous post was at 09:33 AM ----------

new update: was able to get TWRP installed from one of the files from the thread, boots to the welcome page and then reboots and enters bootloop. Are there any files I can flash from TWRP that might save the tablet?
[Walmart Onn Tablets General] tek3195:
If you go to the link I posted and get the files from CaffeinePizza's server you can fix it if it can be fixed with software. Grab files for your device, that copy of SPFT and those MTK drivers. When installing drivers make sure it is recognized as mediatek and not kedacom device or whatever it is that these tablets show as when plugged into windows. Drivers have to be correct or it will not work. If your on linux and have spft working follow instructions from CaffeinePizza and it should work. I say should as I have never gotten spft to work correctly in Linux, but if you use windows it will work, it will format your device and it will flash it complete stock to the point it will take an ota via adb. That is the only way that I know of that works because I have done it several times with mine. I'll look and see if I can find his instructions for you.

here it is. it works if you do exactly what it says. Alter or omit anything and your pissing in the wind.

[MENTION=245884]tek[/MENTION]3185 is 100% correct [MENTION=4002472]jdelfin85[/MENTION]. When fastboot doesn't work, the only surefire way to restore it is with the SPFT as [MENTION=245884]tek[/MENTION]3185 has explained it. This method will even recover a hard bricked device in most instances.
[Walmart Onn Tablets General] jdelfin85:
Sad to report that neither method worked, which is leading me to a hardware problem, which doesn't merit to fix. It will now load to the welcome screen, but then immediately freeze or reboot, then get stick in boot again. It was a good fight but I think bad hardware won the good war. Thank you both for your help!
[Walmart Onn Tablets General] tek3195:
If you can get twrp on it with SPFT there is another option. If you can find someone on here with 003 willing to take the time to pull protected partitions by using dd command. You can place them on ext_sdcard then dd the imgs to their appropriate partitions with adb shell thru twrp. That would be time consuming and can get confusing if done by-name. When I have done it in the past I used /dev/block/mmcblk0p? that way if you lose your place on your list you can just look at last number copied. If I had 003 I'd pull them for you. And yes, I know here are quite a few 'ifs' in this possible solution. But, if you can get imgs you have nothing to lose at this point.

You do have a hot battery, right? Dead battery will cause all kind of problems with these tablets.

---------- Post added at 07:46 PM ---------- Previous post was at 07:41 PM ----------

just to let you know you can flash a .bin file with fastboot
[Walmart Onn Tablets General] jdelfin85:
I bought a replacement battery because I saw that these had issues with batteries and hoped mine would be that solution. I will have to wait to be patient to see if anyone in the thread has any insight they could give me on those protected partitions. I find it rather incredulous that a janky Walmart tablet can beat me... At this point I just want to do it to really drive the point home to where I bought it that they have crap quality control. I am going through this with this one and a ticwatch- both bought refurbished. I guess I learned my lesson the hard way buying refurbs and being out of the US. Should I check out the other thread you sent me to see if that has any other information about the partitions? At best I'm just cleaning up someone's bad software job, at worse a walmart lemon.
[Walmart Onn Tablets General] tek3195:
There were a bunch of times I felt that way with these tablets. I started that other thread and got the Walmart general section started. You should have tried it when there was no thread to turn to, it sucked. You can look around and see what you find, there are a lot of threads I haven't even opened so I don't know what all is available now. when you enter a thread use the search box at the top with a few keywords and it will make it a lot easier. You can look for post by people with your model and ask them directly if they have or will get. That can be done by a simple reply to post instead of PM.

Also, I would try running it through SPFT a few times making sure it was done correctly. Green checks where they should be and get creative with partition selection. I can't remember now but once I had to flash mine in sections so to speak. I posted it somewhere about recovering from a brick. It made no sense then or now but was what I had to do. It doesn't seem like yours would boot or loop then freeze if hardware, still sounds like firmware or software. Either keep at it or cut your losses but don't consider it a loss, rather the cost of learning about refurbs. You got away pretty cheap if you look at it that way.
[Walmart Onn Tablets General] jdelfin85:
So things are starting to get a little more interesting... Today I was able to get it to boot up to get access to the system even for just a few moments, I am going to charge it up again overnight, and see if I can get anywhere with the bootloader unlock. If I can get that far, are there any other software options I can look at? I will have to be doing most either through recovery or through fastboot, and while I have been doing pretty well over the last couple of days, I am still a little rusty on flashing ROM's (I ahve been in the pixel world the last few years, and havent had the need to flash. Any options for me if I can manage to get that hurdle cleared?
[Walmart Onn Tablets General] jdelfin85:
[MENTION=8491352]tek3195[/MENTION] I started ed fiddling with it a bit tonight and came down to hardware... When the processor starts getting warm it kicks into bootloop. I power it down, put it in the fridge for a few minutes and boots right up. Reminds me of a problem with the nexus 6p that had to be put in the freezer to apply a core fix. For this tablet I'm assuming that means the motherboard is burnt. Unless there is a way to patch the processor (and even then, I don't know what part is getting warm) I think it's safe to say I have a lemon. I'm still up for ideas if anyone's got any, but this is going to go in the drawer of parts, o spend the rest of it's days with my infant son so he stops with our phones.

I really hate losing, and since I have already had to do a chargeback against the seller, I bought a board and having it shipped. She will live again!
[Walmart Onn Tablets General] tek3195:
Don't do like me and keep at it til you have to much in it to let go. I've got a Tab S2 that I have way more money in parts and repairs, not including original price, than what I paid for my new Tab S5e. The midframe plastic piece is the only original part left, but each time something went wrong it was cheaper to fix than buy new tab.

Anyway, cool you got one coming. Where did you find a board, ebay ?
[Walmart Onn Tablets General] jdelfin85:
I started down that road this year with my pixel three, sometimes it is easier because I am out of the country to order parts but you gotta know when to let it go. I bought a 4a and I'm waiting for that one to come. I got a refund on the tablet, so I only have the battery that I bought and a motherboard. $45 into the tablet, and if this doesn't solve it for any reason I'm at my cost for what it would have cost to send it back to the states and I'll cut my losses. Did a quick search on Ebay and it was one of the first ones that came up. The tab is going to go to my son, I had to get a replacement anyway for school, so alls well that ends well I guess.

ANYONE HAS FULL STOCK FOR Onn 100005208

i have a tablet thats bricked saying i need to enabled dram failed
[Walmart Onn Tablets General] Viva La Android R.I.P.:
I have not seen an official stock firmware package for the Onn Surf 10.1 (100005208). But I do have a set of stock firmware images I pulled from my own 100005208. Are you able to access fastboot mode? And is your bootloader unlocked? If you can access fastboot mode, you will likely be able to unbrick your device by fastboot flashing the unmodified stock images from my device.
[Walmart Onn Tablets General] jjvcuyler:
I think I'm in the same boat. My bootloader is unlocked, and I can access fastboot. If you share those images with me, it'd make my week!
[Walmart Onn Tablets General] Viva La Android R.I.P.:
This link is for an archive containing six partition images for the Onn Surf 10.1 (100005208). These images correspond with the Android 9 Pie firmware, Build No. 100005208_20190731. When you extract the contents of the archive, you will have these six images:

boot.img

system.img

vendor.img

vbmeta.img

dtbo.img

metadata.img

These are pure stock, untouched partition images.

Getting your device to boot up may be accomplished by flashing only the boot.img and system.img. However, to ascertain that firmware doesn't get mismatched with software, flashing all six images would be wise.

https://drive.google.com/file/d/1-KPwc_bCSs_zWkLzlkSTaPySabmgd_HB/view?usp=drivesdk

If you do not already have platform tools or the Android SDK installed, I would recommend using Minimal ADB & Fastboot v1.4.3 https://drive.google.com/file/d/1Qj4XzdXcq_YDhQ6bcipBx-vCg3rNj_Lz/view?usp=drivesdk

Note that the system.img is a rather large image file (2.50 GB). When flashing this image with fastboot, you will receive a header size notification in the command window. Disregard it and be patient. Fastboot will automatically convert the system.img into a series of sparsechunk files that will systematically be flashed to your /system partition. This can take several minutes so just be patient. Also, this archive does not contain the stock recovery.img. Should you want the stock recovery let me know and I'll try to locate it. To get your device up and going, you won't need the stock recovery but it is handy to make OTA updates easier to install. Here's a link to an untouched OTA update.zip for the 10-10-2019 update. https://drive.google.com/file/d/1-XYanOXS_SClKmGocQKesQF_jschzdNW/view?usp=drivesdk as well as a scatter file for the 100005208 tablet https://drive.google.com/file/d/1uuYranunZVjiT9RidUSMuixXSTCnhT5F/view?usp=drivesdk

Once your tablet is booting properly, if you want root, just flash this boot.img with fastboot or TWRP recovery. This boot.img is patched for systemless root via Magisk v20.4-stable, dm-verity disabled and force encryption disabled (opt encrypt). https://drive.google.com/file/d/11Q7_ggVqfai-3jTNbfeiL79pKqshsLle/view?usp=drivesdk

[Walmart Onn Tablets General] KaosKreationz:
To be quite honest they are pretty badass for the price. My 10.1 is sitting with the 8 core at 2.3ghz and the flu is pretty decent too. After the root and bloat ware removal they are pretty speedy little tablets. I’m having a hard time finding the Walmart button system app. Curious as to what it might be named as it’s not the same as the 7 I have it was plain as day. I did run across an app called wmapps which I figured was acronym for Walmart apps I removed it but the button is still there. Maybe when I reboot it will be gone not sure but I am going to start developing an aosp rom for both devices and I’m definitely looking into an Ubuntu touch distribution that I can possibly

Get the drivers for and build it up specifically for thieve devices. Should do well with a Linux destro. Imho. I really wanna contribute here and get further in my personal project so.
[Walmart Onn Tablets General] will160628:
Roll backs

From my experience with other tablets in the Onn line up there shouldn't be an issue if you do a full install in sp tool. I can confidently say a partial restore from differing ota updates will soft brick you in most cases but I don't think Onn does any anti-roll backs on these devices. I've only done a restore from about 3 updates difference though. I haven't had a need to go any further back yet.

---------- Post added at 01:26 PM ---------- Previous post was at 01:21 PM ----------

The wmapps will kill the button from opening anything but adjusting the actual buttons has been a bit difficult given google removing most of that functionality in android 10. I'm actually considering restoring that apk since the button causes a crash without it.

By the way if you haven't already tried it, changing the cpu governor helps make these tablets even more responsive but they do take a pretty hard hit in battery life.
[Walmart Onn Tablets General] KaosKreationz:
Thanks for the info what app are you currently using for OC or cpu governer change. im not concerned about battery live however i am concerned at the rate at which they charge. curious if the magisk charger module will help them quick charge or possibly slow it down even more.?

Also what and where is the button stored in? Could possibly recompile whatever apk without it or at the very least change the icon of it and program it to be of use. I was thinking like a utility launcher or magisk manager launcher. either way I really want this gone. starting to develop an AOSP for it ill inform on that once i have something of value to contribute.
[Walmart Onn Tablets General] will160628:
Mods

I generally use ex kernel manager when custom kernels aren't available. There are more granular apps I've used in the past but android 10 has made most of them obsolete. On the charger front, most of the plugins I've seen will actually slow charging to help extend battery life. Given the type C charger your best bet is to get a belkin or other reliable brand charger that supports quick charge. I don't think these devices have quick charge support but using a better charger does seem to help. Personally I use nekteck chargers from amazon. Just be careful what you get. Try to make sure anything you get has USB-IF certification or you run a chance of burning up device charge ports. No aliexpress cables/chargers if you can help it. ;)

Its been so long since I tried editing the bar directly, I honestly don't remember much about it and I don't think much of it would apply in 10 anyway. I'm not sure if its true or not but the actual icon looks like its named orchid if you look through everything installed in titanium backup. I don't know if removing the icon files will cause it to disappear or if it will cause android to completely crash. I haven't gotten around to trying much with it for a couple days.
