Hi All,
I'm in a bit of a unique pickle. I have a Lenovo ThinkPad Tablet 1838-CTO, it is a US 32GB wifi-only tablet with all stock hardware (with disconnected keyboard folio).
I am running build number ThinkPadTablet_A310_02_0037_0075_US
It is not liking to play more than 5 minutes of a video before saying video cannot be played, video it played fine before. Tried all the standard steps, recopying, rebooting, etc etc. The device also sporadically reboots 20-30 minutes into use, sometimes. I have root, rootprotector, and I have CWR. I have not used my tablet since about a week after the first update from my current version above: my device went loopy, THEN the update failed, and I stuck it in a closet, $%^@%$*&@ed off at it for not working.
I want to either (depending on difficulty, and recommendations here) update my device to the latest Lenovo ICS *OR* Run a custom JB ROM (perhaps http://forum.xda-developers.com/showthread.php?t=1778375 though it is for ROW not US, unsure if that matters). Priority on maintaining root access, could care less about what recovery is used, etc.
OTA updates are failing since I had to get CWR , and I am not sure how to use CWR to manually patch/update.
As for the glitching and all that, I am fairly certain it has something to do with when I rooted it, I was a very early adopter of the first permaroot (I place no blame except myself for any and all issues, and muchly appreciate the efforts of others in allowing me to root my device, whether it bricks it or makes it 10x better). I just want to update my device to ICS and start using it again. I have done some searching but am finding that almost everyone is using 0089 or later with the same issue I have, trying to get back to stock bootloader. Honestly I would like to get it on Lenovo ICS, maintain root, and go from there.
I appreciate any and all advice, it's a personal device so I am fairly lenient on what I am willing to try.
Update: I would most appreciate a stock Lenovo ICS dump flashable from CWR if someone knows where to get one, again though any help at all is appreciated.
Update 2: CWM 5.5.0.4 unable to mount the SD card (/sdcard - not even sure if it is trying to mount internal or external, I have ALWAYS had nothing but issues with the external ALWAYS being write-protected no matter the position of the physical slider switch, though it always reads fine - Sandisk 32GB micro-SDHC with Sandisk MicroSD to SD adaptor), so flashing anything from CWM is a no-go. I want to take this thing and send it on a flying ride out the window, the only thing stopping me is it would probably survive just fine to spite and mock me. Sorry about being long winded, rather give you guys as much as possible info.
Is rooting the tablet all you've done? Did you remove any stock apps? I had the same problem with my TPT when I tried upgrading to ICS(from build 0089_US on wifi only 16GB)but only because I had a corrupt busybox file or something. Try going back to complete stock(NO recovery no root) and try to do an automatic OTA 2, then OTA 3. It should work.
How do I go back to stock recovery/bootloader? I rooted back when you had to swap in ClockworkMod Recovery, so my updates fail consistently when I have to reboot to apply, my guess is that the updater tries to pass calls to the lenovo bootloader that do not exist with CWR.
If there is a way to restore my bootloader then I should be all set, otherwise I think I need to find a good cooked rom

I posted an ICS Nandroid from a US 32GB TPT, exactly what you are looking for, here:
http://forum.xda-developers.com/showpost.php?p=28240019&postcount=14
It will return you to stock Restore, losing CWM, but you can reinstall a proper CWM for ICS afterwards. See the Development Forum for the updated CWM version that works in ICS/OTA3.
You will have root, but you must download and use OTA Rootkeeper to bring Superuser back (don't forget to download and open SuperUser from Play store).
Good luck!

Going to try it tonight/tomorrow. Updating my Vivid to a non-corrupt CWR then flashing HolICS 1.3 from 0.9b tonight. Oh the adventures I get myself into... XD
Thanks for the upload, I'll let you know if(when) it works, either way I appreciate the effort!
I have been reading for many days and there is no way I can get into fastboot , to install new system ,no boot logo, not fastboot.
I have some other way to repair fastboot?
Is it possible to delete the fastboot?
If so, can it be rewritten?
thanks
Pro, or Standard?! I don't know what to tell you about the Standard though.
If it's the Pro we're talking about I would slow down FAST! And, have a look at the SSHD to SSD Migration Threads here first. Namely the bits on cloning it. Which might at first seem to be pointless. But let me explain.
Each Shield TV has a hidden Partition inside the SSHD that contains the valid Widevine L1 Keys. In short you will want these if you have plans to use either Amazon, Netflix or <Insert other heavy handed OTT Service here!>.
While you may have forked the Bootloader to a permabricking state. You could use the Op's Backup Image of his own Shield TV which he was generous enough to make public.
That however would way out your own Keys FOREVER! The practical upshot would be like an XBOX Live Permaban.
So heres the "Idea", you backup what's left of your SSHD Under normal circumstances you should never have need to touch the Security Sectors of the SSHD. Once you have made that Backup... Following the info from that Thread. Go ahead and install Ops backup Image to your Shield.
(Full disclosure) It's to late for me, so I can't tell you exactly which Partition you need or which DD command to enter, in order to flash back your personal Security Sector to your Device. I think I may have inquired about it in that Thread. But not having bothered to make a backup even at that point means I no longer have those Keys, even if I do have a working Shield TV. But as long as you can replace the correct Partition with the One that came with the Shield you should be able to recover.
Now outside of that advice. You really don't need to ask me anything further. Again I never managed to get that far. I was going on what turned out to be false information at the time that only Netflix would be affected, by a broken ESN. What the people in that Thread probably faild to realize was that it was the Widevine Keys that were to blame. So I thought ok fork Netflix! As long as I can use Amazon.
Needless to say: WRONG ANSWER!
But, if I were in your shoes​ now, the above would be my plan of attack. But, I'm not the One to be asking about how to do all of that. Besides most of the foreseeable questions should already be answered there.
if you cant boot into bootloader or fastboot mode, at least in 16gb, your screwed. Better request for RMA.

If you have a "Standard" (i.e. The 16Gb), then it's pretty much the end of the Road for you. As there is no way outside of a nVIDIA Factory, that I'm aware of that would allow you to recover your Bootloader on an eMMC Chip. Without some very expensive equipment, and some very MAD SKILLZ. Apperently someone here managed to do that by upgrading the Chip to 32Gb's, from the usual 16. But, this is likely beyond the scope of most People.
It kinda sucks to say it, but I think it's time to start looking for a replacement.

It is possible to delete the fastboot if you've performed this command
fastboot erase bootloader
If not, I suspect that you just can't deal with the hardware trick to enter the bootloader which it is tricky indeed
- with the TV box disconnect from the power cable
- Connect the hdmi both to TV and TV box
- connect the USB cable to both pc /laptop and TV box
- connect the power cable and on the next split second hold the power button of the TV box for few seconds, it should go to bootloader
From there, use the Nvidia TV box recovery image to flash it, there are instructions on website about how to which consists on a set of fastboot commands
Before starting be sure that the fastboot drivers are correctly installed and functional
Sent from my Darkside of Oneplus 3T
it is clear that OP's device is in that state because he already flashed something (wrongly) and nuked the bootloader.
If he already flashed something, it means he knows how to get into fastboot or bootloader mode, so that is not the issue. The issue is that OP bricked his device by flashing wrong bootloader, and if the bootloader gets corrupted in 16gb model you won't be able to boot into that mode, thus not able to flash anything anymore.
Best advice is to request for RMA.

Hi there,
i got a little question prior rooting my Shield TV 2017 pro.
I read a bit about the L1 +L2 Widivine keys on the shield so my question is, does rooting the shield has any influence with the keys, for example will Amazon + Netflix 4k stream work after?
The second question is, is twrp on the shield able to create a backup of thoose partitions in case the hdd bricks or something went wrong during flashing?
EDIT:
In case anyone needs the answer, too just read the two following posts by lavero.burgos and mr-tee and some warnings from ichijoe in 3rd, which are very detailed and helpfull
Thanks in advance

Hello, the answer is NO, rooting your device will NOT mess with your keys nor damage them, simply because as systemless root it only safely modify boot.img and the rest goes to the data partition, so it won't touch sensitive data. The recommended method is to install SuperSU which is developed by Chainfire (the guy know what he does, he's an excellent dev).
Netflix and Amazon work for me with root, but yes there are services out there with their own apps that don't allow root. If they detect root you won't be able to play their content (IMO bad practice, i would change service if that is the case).
About TWRP, no it won't allow you to backup the relevant partitions because TWRP handle standard partitions that every Android device has, so unless someone makes a custom TWRP to include that the only way i know off is running dd comands from linux distro to backup the needed partition(s). I have done it myself in the past (many years ago) with the old Nook Tablet.
I made videos about that but you first need to know the partition block name, for example mmcblk0p8, once you have that info you can go to YouTube and search how to backup partitions with dd command and also check the following playlist where you can find the videos i made long ago:
Community Forums: http://www.youtube.com/playlist?list=PL216837379418927A
I'm very curious why many 500 PRO users have bricked their devices. What you really need to be careful with is the bootloader (blob file), don't mess with it. You can no longer downgrade bootloader from Nougat or newer to MM or older and in case you want to upgrade your hdd with a ssd and clone it then you also have to prepare to damage your device in the way.
I only have the 16GB 2015 model but would be great if someone post a screenshot of the famous backup a user has posted for the 500GB PRO, i would like to see what is inside.

First of all I would say, try root first, see if it affects the apps you want to use.
Don't FLASH TWRP, yet tell fastboot to boot the recovery image. But even flashing it won't harm anything. There are stock ROMs on the nvidia developer website, with the original recovery image, so you can always flash back the stock recovery, but well, not flashing a different recovery will save some effort and time.
If you have installed supersu you'll be able to fully UNROOT inside the supersu app. So, first try it out, without changing any system files, see if the apps you use work, then you could consider going further with customizations. But you can always return to stock, just don't mess around with files outside the system or vendor folder. And especially not the bootloader (blob). But there is a blob file inside the official stock ROM from nvidia.
One warning: DON"T use the flash-all.bat file included in the nvidia ROM.. use the commands manually...!!
Thanks for the detailes answers, yeah i know about dd commands, and fastboot or adb, just wanted to be sure that nothing strange happens.
Cause i never got any Widevine L1 certified device
So tonight rooting a shield...
To answer some of your questions.
Rooting will NOT mess with your Keys directly. But, sooner or later nVIDIA are going to start lobbing Updates again. And, if you have a setup which involves say a 4k (2160p) TV*. Then you CAN NOT just simply load up TWRP from some location. To do your business (i.e. rooting it), then exit back out and leave the Shield otherwise stock. (e.g. you never actually replaced 3e (or whatever nVidia calles the Recovery, with TWRP.)
This does not mean that you can not install (i.e. replace) 3e, with TWRP, and then just boot into that. That, would work perfectly, and that's what got me into the deep Dodoo.
Again whatever you do DO NOT replace your Recover with TWRP! Sooner or latter this will bite you in the 455! The moment when nVIDIA decide to push out an update, and sends your Device into a bootloop. Which will make you want to downgrade, and then hardbrick the Device.
But, beyond all that, there are plenty of other good reasons to make that backup of the original SSHD. Beyond having a simple backup of just the Keys. As these Drives, like all Drives eventually fail.
* I gather those with them old fangled 720p, 1080p Sets out there will NOT have this problem. Which I can confirm, as I can load up TWRP just fine over the fastboot command line on my Old Man's 1080p Samsung. Alas back home it's just the One 4k Set. And that will not work. Unless loaded directly on the Device.

Thanks for the hints, the way i would root the shield would be:
-Unlock Bootloader
-fastboot boot twrp.img
-flash the su stuff
I got no need atm to replace recovery, so i keep it stock, just want root for droid mote, launcher and maybe xposed, and a dd backup of the whole shield hdd

As long as you do NOT replace the Recovery with TRWP. But, just call it up though Fastboot ~boot recovery <path to TWRP> then you should be nearly 100% safe.
But, having learnt my own lessens I would personally recommend leaving the Shield alone I'm not sure what good Rooting it actually has. And I'm a very big fan of AdAway, but AdAway just doesn't seem to do jack on the Shield. And, though you have to root to add Unofficial channels to Plex. At the end of the day. Those Channels have like for like Kodi Addons.
But again as long as you don't flash (replace) the stock Recovery with TWRP, you should be ok. Assuming an Update rolls along, (as they do), you should just be able to load up TWRP, like before, and flash SuperSU, and then go on with your business.

Those steps are correct, just know that in a 500gb PRO model unlocking the device will securely wipe your device and that task takes around 2 hours to complete in that specific model.
You can also use adb to sideload SuperSU package while in TWRP (Advanced >> ADB sideload):
adb sideload supersu_package_name.zip

As title. I have just purchased a 2017 Shield TV, and it came rooted with Pie 9.0. Now, I don't really care for that at all. I mostly just use Plex with my devices, and that's why I bought this. Save me turning on my Xbox One X just to watch a movie, ha ha. I don't really want an extra "warning" screen when I boot it up, and would prefer it to simply just work from the remote (I may consider selling on the controller as I have multiple xbox / PS4 / Switch / 8bitdo controllers if required).
Anyway, as it has full Android on there, rather than the original Shield OS, do I loose anything with respect to the Plex app (which is my most used app), or Amazon Prime Video? Are there any other media limitations that I may experience from running a rooted system?
I am relatively happy with flashing firmwares and such (I regularly play about with CFW on my Switches and Vitas). So is there a guide anywhere that will show me how to put this shield back to stock? Rooted or otherwise.
if you want to flash the device back to stock go here
https://developer.nvidia.com/gameworksdownload
make sure you read everything about how to do it first and make sure you download the correct rom image for the correct device otherwise you will brick the device.
i have the 2017 16gb model with the developer rom (stock rom with root capability). i rooted mine with magisk but really i don't see any reason to really root it other than adblocking. i use mine mainly for plex and iptv. i do use atv laucher pro. i don't like the stock home screen setup. also i can download just about any app from https://www.apkmirror.com/ put the apk on a usb stick and load it with es file manager or even the stock file manager software.

Thanks for the help. I got there in the end. Had a panic when it refused to boot, and couldn't get into fastboot to try a factory reset, but plugging my keyboard in, rather than the controller, and locking the bootloader helped that.
Now back on stock and got it all set up and running. As expected, Plex is MILES better than on my Xbox One X...
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.

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`.

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.

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.
