My tablet currently has TWRP (latest version from the StockOTA tutorial on the forums) installed as well as a custom rom (CyanogenMod) installed on to the tablet. I'm looking to restore Stock or an optimized Stock rom onto the kill switch wifi K1 tablet, but the problem is I can't find the latest available OTA download? Is it the Recovery OS on NVIDIA's site?
Are these the right steps to have me running the proper setup?
Boot TWRP Recovery
Flash NVIDIA SHIELD Tablet K1 Recovery OS Image (5.1.0)
Flash TWRP Custom Recovery (Supposedly this gets erased in the process from what I've read on the forums)
Flash 'nomoreota.zip'
Flash 'SuperSU' from the stockOTA thread
Delete some sort of (Nvidia or Stock)OTA.apk file in the system partition
If anyone has any suggestions or tips, please help if you don't mind. I've read through a couple threads here, and honestly, I'm pretty lost...I just think that my current rom is lacking in performance, but I don't want the device to brick.

My device:
- TF300
- Android 4.2.2. / CM10.1 (10.1-20130621-nightly-tf300t)
- WW_epad-10.4.2.9-20120809 (= 4.1 bootloader version)
- TWRP 2.6 recovery (for bootloader v4.1)
My aim is to update to CM10.2, therefore I need a bootloader version 4.2. I downloaded the latest firmware from the asus-website (TF300T-WW_epad-10_6_1_27_5-UpdateLauncher.zip) and put it on /sdcard.
But I'm in doubt:
- Is the asus firmwire described above the best way to upgrade my bootloader? And can I use TWRP to install this zip?
- If so, do I need to change the TWRP version to 2.6 ready for -4.2 (teamw.in/project/twrp2/97) not at all, before or after I installed the new bootloader?
I know bootloader/recovery issues can easily brick a TF300, so to be sure I ask. Thanks in advance!

I flashed the blob via fastboot. Then flashed recovery via fast boot. Then cm10.2 from recovery. I was on old June build of 10.1 and 4.1 bootloader same as you. Be safe fastboot flash follow guide in q and a section

Same question, but not exactly answered: can you do this without a cable connection with your pc?

Honestly, I'd rather be safe than sorry when upgrading bootloaders. So I would always suggest using the cable connection because it is less likely to fail. You probably could get away without using it to flash stock, but you wouldn't be able to flash TWRP without fastboot, and then couldn't flash a custom ROM. But everything feels safer once you have Nvflash backups.

I was in the same situation as you not so long ago. Was on 4.1.1 with TWRP 2.6.3.0 JB installed. Asked myself these questions repeatedly. I updated via fastboot to the staging partition using the blob within the latested ASUS firmware zip file. The blob file contains, bootloader, recovery, system and boot. This means your are essentially returning to stock everything upon flashing. This was a huge sigh of relief as I didn't want to brick my device because of the same concerns you have. So I flashed via fastboot to 10.6.2.10 then flashed to TWRP 2.5.0 4.2 as 2.6.3.0 didn't work for me for some reason. I heard a number of people say that 2.6.3.0 4.2 is buggy and suggested to stay with 2.5.0 in which I would recommend from experience. Then flash your custom firmware.
Pretty lost by now. I am still (sick of it) on an unlocked Asus stock 4.2.1 with TWRP 2.5. My intention is to change the ROM but was considering CM 11 which I understand does require TWRP 2.6.X at least. I was hoping for a fix for installing navflash on post JB but I believe does not possible so anything that means touching the bootloader makes me very concern.
I was wondering:
- Can I flash TWRP 2.6 (4.2 img file i beleive) directly from my already installes TWRP 2.5 bootloader and then install CM 11? or do I need fastboot process again?
- Is CM 11 worth on the TF300? I just need some stability and reasonable speed after having so many problems with the stock rom.
Thanks.

Yes, CM11 requires TWRP 2.6.3.1.
You can install NvFlash on a JellyBean Bootloader, link and guide is in my signature.
If you bootloader is above 10.6.1.8, you can just flash the TWRP 2.6.3.1 and then reboot and then flash CM11 + gapps.
I think it is super smooth with the OC Kernel.
Hi everyone,
I'm on custom recovery TWRP and everytime i download the OTA 1.2 and try to flash the tablet goes on the custom recovery but doen't flash the update.
Probably because of the custom recovery.
Is there any way to manually flash the 1.2 update?
Thanks
You can flash the stock recovery, ensure all the apps you've frozen are unfrozen (this mattered when the 1.1 incremental was released - checksum matches require all apps present in the previous build to be "visible"), and then apply the update.
Someone else may have a work-around.
There are no fully working custom recoveries for the Nvidia Shield Tablet so far. I would suggest staying on the Stock recovery until they are working correctly, just my opinion.
I recently bought a TF300t second hand and I really need some help! Some years back I was playing around with custom roms on Android devices but im very out of touch.
I would like to install one of the more recent roms on this device. Any suggestion here appreciated.
The device has already been rooted and has TWRP v2.6.3.1 installed. I understand that I need to upgrade this to 2.8. to install the latest roms but im having issues doing that. For a start im unsure how to find out if I have the latest Bootloader 4.2
I really dont want to brick this device!
I tried using ADB to update TWRP but the usb connection never seemed to find my device in the right mode.
The device is currently running Android 4.2.1
Custom ROM CROMi-Xenogenesis 5.4 - 10.6.127.5 WW ODEX.
Any help and advice really appreciated )

Android 4.2.1 is newest official.
10.6..... is bootloader version - newest there is.
flashing recovery and/or ROM will not overwrite bootloader - it stays the same.
You can go to twrp official website and get 2.8.0.1-4.2 blob to flash (unless your target rom states different version needed - see 1st post of yout target thread) - I got it from there - flashed KatKiss using it.
ADB - when android is running.
fastboot - on bootloader screen (booted with voldown+power - RCK / android / wipe data icons) - used to flash twrp blob

Ok got it all fixed now. Thanks!
So, not to hijack, but I'm actually in a similar boat. I'm currently rooted and unlocked on 4.1.1 TWRP 2.3.3.0 and am looking to flash the new 5.0 Rom.
Does anyone have a handy guide on what I should do? Do I just need to flash a 4.4 compatible TWRP version, then flash the ROM? Would like to avoid bricking my tablet.

Yes here you are ....
Get the SKU from your bootloader screen .....
Then go to the Asus website and get the firmware for your SKU ending in 27.5 ...
Then unpack the zip and there will be another zip unzip it you will find a file called blob ....
Flash this blob from fastboot ...
Thx Josh
So I've been trying to update my Shield LTE ROW since this Friday from the stock based rom LL (version 3.1.1) to the MM-based rom (version 4.2) and spend a dozen of hours failing to update :crying:
When I install a MM-based rom the shield boots and the nvidia logo shows a few seconds and then the screen goes black. When the tablet is attached to my pc I noticed that the tablet is not turned off but booted in APX-mode.
These are the things I've tried:
Installing the recovery image 4.2 (fails)
Installing the recovery image 4.1 (fails)
Installing the recovery image 4.0.1 (fails)
Installing the recovery image 3.1.1 (works)
Installing several full and incremental OTA updates to 4.x (fails)
Installing CM 13.0 (fails)
Installing carbon 5.1.1 (works)
Followed the guides mentioned in topics: http://forum.xda-developers.com/shield-tablet/help/unable-to-update-to-marshmallow-rom-t3444124 and http://forum.xda-developers.com/shield-tablet/general/unofficial-update-original-shield-t3281541 (fails)
I've tried a lot of things, but now I'm out of ideas.
Has anyone a explanation why MM-based roms don't want to boot on my tablet? And has the knowledge to fix this?
All feedback is welcome and appreciated.
You are currently able to flash and boot with 3.1.1 or stuck in apx mode?
I'm able to flash and boot with 3.1.1. Only MM-based roms are stuck in apx mode when booting.
You are probably on the Lollipop boatloader still. With that bootloader MM based roms don't work. Flash the latest stock from here, root it with cf-autoroot, flash twrp and MM based roms should work.
Thanks for your advice, I'll try it this weekend.
Just a quick question, why do I need to root and flash twrp? Shouldn't it work if I only flash the latest stock?
Hi,
Hardware: Original ASUS Transformer tf101
OS: Latest official ROM / update (Android 4.0.3)
Trying to make this thing usable again, which it really isn't in its current state.
It's been incredibly frustrating and confusing even getting this far (mostly because being an absolut noob (somewhat experienced Linux Admin, but no idea about Android, ROMs and Rooting) and also because the tf101 is obviously antiquated), but somehow I managed to both root the device (or at least the Root Checker App tells me so) and install a custom recovery (CWM) - but now I'm stuck because CWM won't let me mount anything containing the ROM I want to install (KatKiss 6.0, seems to be the newest available; not great, but better than 4).
So I tried installing TWRP instead of CWM - but I really don't know how. There are several ROM utilities that should be able to do this, but the only one that has been working so far was ROM Manager, which I used to install the currently active CWM. The TWRP App keeps telling me that it can't find the recovery partition, which I'm guessing is happening because it's looking for the original recovery and not CWM?
