[Shield Tablet General] robstyleX:
Hey there, good post! Thanks for the info. :)

I am a new owner of a Shield Tablet K1 and looking at modding some things (like adding the stylus features back in and gaining root). I am quite experienced in modding and that stuff, I do know how to operate fastboot and adb, so the basics are covered.

I still have some concerns and wasn't able to find something yet since most posts are about the "old" Shield Tablet, so I am sorry to bother you with a few questions (since I want to be extra sure and not assume both are the exact same).

Can you tell me whether unlocking the bootloader leaves a trace? If I happen to need to file an RMA request, will flashing back the stock stuff and relocking the bootloader make the tablet look "as new"? I know some devices put a "tampered" flag in the bootloader screen or say "relocked" instead of just "locked" so anyone looking at that will instantly know that I've tampered with the software and deny warranty claims. Could you please tell me what you know about the possibilities of reverting to stock without leaving a trace?

Thanks in advance :)

Oh, and have fun with the new hardware! :)
[Shield Tablet General] Techamazon:
Heya. As for losing warranty due to unlocking the bootloader, that's something you'd have to ask Nvidia since they also tell you do it when re-flashing as seen in this README.

Either way, a retailer couldn't tell otherwise unless they were provided by some diagnostics tool that specifically showed some hidden logs unless a dev here could fill us out on that? I'm in the process on getting my K1 replaced by a new one since the wifi related issue I have is due to borked hardware.
[Shield Tablet General] robstyleX:
Okay, thanks for the answer! :)

I think I'll do some further research and then see if I go ahead and root it. What's that re-flashing thing about? Is it a guide by Nvidia to restore if something gets corrupted?

Hope your replacement goes through without problems!
[Shield Tablet General] Vartom:
What version of firmware is installed on Shield tablet K1?

Where it can be downloaded?
[Shield Tablet General] Techamazon:
Indeed it is

They actually offer you files to reflash Stock in case of any hiccups or whatever. Warranty at best is covered by Nvidia but not by the retailer if they're still living in the 80s.

K1 firmware is not yet available. But flashing the firmware for 1st gen is there and compatible with K1 (both are 3.1.1/5.1.1)
[Shield Tablet General] markstibbyspot:
Nm...still confused. Lol the firmware links posted are stock or modified? How did you get max performance?thanks!
[Shield Tablet General] Techamazon:
Firmware links are directly from Nvidia. As for Max Performance, Optimal, and Power Saving... It's in SHIELD Power Control.
[Shield Tablet General] markstibbyspot:
Ahh makes more sense! Works perfect!

[MENTION=5614267]PixelVixen[/MENTION] did you try [MENTION=5123642]lj50036[/MENTION]'s 2.8.7.3 TWRP he released? Could you try it please.

If it works we know that the K1 is compatible with our roms going forward as well
[Shield Tablet General] Beyondcr:
Do you think there would be enough room to fit a pigtail over to a dipole wifi antenna where in the stylus chamber?
[Shield Tablet General] Beyondcr:
Ok it looks like you could get a u.fl to sma cable to fit but you will need to have the sma connector protrude out of the case, I guess it will then look like a old portable tv with an antenna sticking out of it... If I was not giving this as a gift I would experiment further but I will leave that decision to the person receiving the tablet.
[Shield Tablet General] Techamazon:
Heya. I'll do some testing come weekend as I've been quite busy with IRL and projects that I've been working on!

edit: 2.8.7.3 is working as intended \o/
[Shield Tablet General] T-Keith:
Any room to add wireless charging?
[Shield Tablet General] ruoani:
It's a hardware thing, not a "room" thing.
[Shield Tablet General] Techamazon:
Just a head's up: Flashing 3.1.1 FW will brand your K1 to a 1st gen device and the 6.0 update now avail will not appear (yet).

edit: I'm still surprised we still have no ways of recovering K1 devices to K1 3.1.1 FW or Android 6.0 for that matter in case of any borkups.

Nvidia if you see this, push it to your dev section! Source is not enough!

Muchas gracias!
[Shield Tablet General] philipp21897:
Could you unzip it for me? I dont know how to do that :(
[Shield Tablet General] DannyBiker:
Any instructions on how to flash the stock Lollipop image ? It doesn't look like a standard zip with all the .img files...

Edit : oh ok, I got, you have to use cygwin for Windows to extract the content of the .sh file and then flash it.
[Shield Tablet General] Techamazon:
Or you could just use 7zip like any sane person would.
[Shield Tablet General] Techamazon:
Uploading mirrors of the STOCK and OTA packages. I've recompressed them with 7zip using LZMA2 at 601MB and 545MB each. This is about half the size of the original links if I'm not mistaken. The same logic applies for applying them. These should come up within an hour or so.

edit: Links are up!
[Shield Tablet General] melendi:
Who can provide me with K1 stock /system TWRP backup?

Only TWRP please.
[Shield Tablet General] 31aces:
Nvidia shield zone.com that guy has everything dealing with nvidia devices. currently waiting for my tablet to get charged and I will be rooting asap. I'm on marshmallow with the 1.1 update have everything except twrp. Last time I checked cpu twrp was still downloading. When I root my tablet I'll check back here dee if still need help but instant answer is that website
[Shield Tablet General] Techamazon:
Just a big fat reminder that anything CM based (12.1/13) will make apps such as RetroArch and Kodi not working properly (no touch function avail).

[Shield Tablet General] chrisjz:
Anyone know if the 2-18 OTA fixes the 'Miscellaneous' battery drain?
[Shield Tablet General] sotoqwerty:
I installed the stock nvidia image, then upgraded to OTA 1.0 and then to OTA 1.1. I flashed the experimental TWRP and made a backup of boot and system partitions. Here is the link: https://drive.google.com/file/d/0B8-42LJtMhdZWGNCZWdzZmJudUE

I think somebody could find it useful.
[Shield Tablet General] crying:
Yeah!!! Last ota? Wifi dix ? Root ? I flash this via twrp and go ? Thank you very much
[Shield Tablet General] Techamazon:
Finally got the Cover and I have to say I'm 99% satisfied with it. I recommend everyone to get it even if you're an casual user as it adds an extra layer of protection. The price is a bit on the expensive side but totally worth it in the long run if you carry it in a messenger/bag like me.

Not planning on doing a full review, though I might add a small one once I review the Shield TV and controller!

Btw: Anyone getting a stretched out Google Keyboard sometimes whenever in landscape and then switching back to portrait? I had this issue on both Stock and now on CM. The only solution I know as of yet is to force close it.

edit: Also coming up in a near future: Logitech K810 and MX Anywhere 2 (been a proud owner of the 1st and 2nd gen MX Anywhere. Sadly these are not compatible as they require a dongle.)
[Shield Tablet General] sotoqwerty:
mmmm. Yep. last OTA and Wifi is working but is not rooted. Anyway you can root it with BETA-SuperSU-v2.67 (just google it).

But the install is a little more complicated. You need to "Restore" the image and should also do a full wipe.

The steps are: (stolen from SharkcpN at another guide )

1- Go in TWRP recovery > Tap on Backup > Select backup location from top bar > Select "System + Boot" > Swipe to Backup > Go Back > Reboot to system. This process will create TWRP directory inside Internal Storage or External SD card depending what you have selected.

2- Download the TWRP backup file from above

3- Extract the contents of the zip. You will see "04244158063450050f8b" folder, open it & you will see "2016-02-19--04-25-34_MRA58K.41524_664.1902" folder.

4- Using File Manager or a PC, go to your TWRP folder inside your Shield K1 where you have backed up your previous ROM.

5- Open TWRP Folder, inside it there should be a "BACKUPS" folder, inside it there should be a folder having your "Serial Number" as its name.

6- Open that "Serial Number" folder & copy the extracted "2016-02-19--04-25-34_MRA58K.41524_664.1902" folder in this "Serial Number" folder.

7- Finally it should look like this : Internal Storage or External SD Card > TWRP > BACKUPS > *Serial Number* Folder > 2016-02-19--04-25-34_MRA58K.41524_664.1902

8- Go in TWRP recovery > Wipe > Factory Reset > Go Back

9- Tap on Restore > Select the location of the copied "2016-02-19--04-25-34_MRA58K.41524_664.1902" folder from top (Internal Storage / External SD Card) > Select 2016-02-19--04-25-34_MRA58K.41524_664.1902 > Select System + Boot > Swipe to Restore > Go Back

10- After going back to Main Menu of TWRP > Reboot > System. It will prompt to install "SuperSU" > Select "Do Not Install"

11- Be patient, 1st boot will take a long time.

Anyway, it seems more complicated than what actually is. It is faster than the whole downgrading + twice OTA procedure.

hey any one know ... if can i instal this stock rom via twrp ?

my k1 dont work! i edit the file build.prop and now only nvidia logo appears

i need to intall this stock rom ??

help please :rolleyes:
[Shield Tablet General] djkinetic:
Why not just push the stock build.prop back in recovery via adb.
[Shield Tablet General] xanthrax:
[MENTION=4979027]sotoqwerty[/MENTION], what's this all about?

Just flash twrp via fastboot and then the superSU zip, don't allow twrp to install root and that's all, no need for all the hassle you described

Sent from my Darkside of Edge plus
[Shield Tablet General] blumzzz:
- I already did that with ADB but dont work may be something gone wrong
[Shield Tablet General] xanthrax:
What is not working? Recovery flash or supersu adb sideloading?

Sent from my Darkside of Edge plus
[Shield Tablet General] sotoqwerty:
The hassle is about using twrp to install last OTA from a twrp backup. It is not about rooting. Basically you create a backup, then use the structure of directories to copy the backup I provided and just restore it
[Shield Tablet General] xanthrax:
but why ? can`t juat be flashed via fastboot ? what`s the problem with it ? or , is it related to the K1 tablets only ?
[Shield Tablet General] blumzzz:
i dont know i try with adb and i put this

- adb devices

(my device appears)

- adb pull /system/build.prop (here say the de system/build.prop does not exist)

and then i put this

-adb push build.prop /system/ (here show some archive was uploaded)

something I'm doing wrong?
[Shield Tablet General] xanthrax:
ohh.. i was talking about recovery , can you try a dirty flash ?
[Shield Tablet General] blumzzz:
dirty flash? sorry i dont know what is this :angel:

can you explain me?
[Shield Tablet General] djkinetic:
In order to access /system within TWRP via ADB you have to manually mount /system from the mount menu within TWRP, once you do that

you can either adb push build.prop /system if you have a backedup stock build.prop or adb pull /system/build.prop and make any edit you need... one thing you must do when you push the build.prop is set permissions with this command: chmod 644 /system/build.prop if you dont set the proper permission you will boot loop.
[Shield Tablet General] blumzzz:
m... i put this comands

-adb push build.prop /system/

-adb shell

-cd system

-chmod 644 build.prop

i see the NVIDIA SHIELD Tablet K1 Factory Image, do you think I should install this image??? or not?

It is simpler than what I think? to instal this image ? or I should try something else?

sorry but i actually I'm desperate... :crying:

and this is the build.prop that i think is ok...(?)
[Shield Tablet General] djkinetic:
that should work, if it still doesnt boot, then go ahead and flash the factory image.
[Shield Tablet General] blumzzz:
i try again and nothing hapens! whit adb ....do you think might be the supersu.zip ? i was reading and reading and i found this (post #10)

http://xdaforums.com/shield-tablet/help/bricked-shield-tablet-t3319254

he said about supersu compatible with shield tablet this apply to my k1??
[Shield Tablet General] djkinetic:
Adb commands will only work within twrp not stock recovery or fastboot.
[Shield Tablet General] sotoqwerty:
I'm no sure that you can flash a twrp backup with fastboot. Anyway I did this because I didn't found any image with the last OTA for the K1. Please just be indulgent with me, I'm not an expert of this.
[Shield Tablet General] blumzzz:
thanks a lot to you guys finally my k1 works!

I install a new image (stock nvidia k1) and now is alive!

thanks to sotoqwerty .

he helped me in the process :good:
[Shield Tablet General] Techamazon:
Heads up! Dirty Unicorns is by far the most customizable ROM as of now. Temasek is the best in CM territory, but what all basic CM13 ROMs lack is real Quick Settings management. Like being able to hide the freaking edit tile button (is that so hard?). Me and myself usually have 3 quick settings on a tablet like Wifi, BT and Rotation since there's no flash/light support or anything other I can see being used that often.

View attachment 3670538

This has bugged me the most in terms of quick settings management which took a turn when CM12 came out if I remember correctly. Even AOSP based ROMs with GravityBox did a way better job or some stock ROMs for that matter.

Out of all I've tried so far extensively, DU is #1 as of now with both RRO Layers and CM Theme Engine (How??? Shut up and take my money!). It also comes with so little pre-installed on /system. SuperSU 2.65 comes pre-installed as well which is also an added bonus. Dirty Tweaks outmatches anything out there so far. You can remove system apps with the builtin tool in case you need to remove excess stuff from the get go.

View attachment 3670540

This was with Xposed and Open GApps pico so yeah, as light as you'd expect. This group really deserves kudos and donations for what it's worth.

so in a sense:

CM + AOSP + über customization options? Pick DU.

CM/13 base with extras? Pick Temasek CM13.

As close to AOSP you can get if you prefer no customization whatsoever? Leave the Stock OS be and don't ask questions on why /system is almost full.

Update: BT is unfortunately as broken as on CM and even FC's if used. Display settings also crashes so keep that in mind. The rest is working as intended.

RetroArch daily (play store) and nightly still lack touch support (CM bug), which I assume still applies to Kodi as well.

Is the new k1 factory img fixed everything?

Or is it going to b a waste of my time flashing?
[Shield Tablet General] zarish:
The new factory image (if like the 2014 Shield Tablet 4.0.1 image) will be the same as the 2016-02-18 re-release of 1.1 (should just call that one 1.1.1 now).

So if you've already updated to the latest, it will be the same.
[Shield Tablet General] skooter32:
So what's new then if its just going to have wifi and miscellaneous bugs gotta luv nvidia lol
[Shield Tablet General] zarish:
To be able to simply and quickly rebuild a device at that version and OS level as a a clean/new device. Pretty much it.

Hey PixelVixen, do you have a fool-proof(ish) method to go from Rooted Lolli to Dirty Unicorns on the K1? If so, can you post it in one of your original posts. Been doing some digging, but info is a little confusing.

[Shield Tablet General] Techamazon:
[MENTION=3401122]XNine[/MENTION] I aim to please ;)

I'm picking up the Shield controller once da money rolls in later this month. As many are aware by now, six axis doesn't work on MM yet so no go there.

My plan so far is to test all known emulators out there and bring up a status report.

As for the most popular one i.e RetroArch, it currently lacks touch support (works fine on Stock ROM) which makes post-setup terrible if you prefer playing with settings (and 3rd party controller for that part) so no go there. I assumed this was a CM13 bug at first, but even with DU which is AOSP based the issue persists.

Kodi also had this problem but was later fixed in an update. Not sure what code is to blame here, that is from the ROM or RetroArch itself.

Update: Shield Controller and Sandisk 128GB 80MB/s reviews coming up during the weekend.

Update2: Finally got the controller! sdcard should arrive any day now.

Update3: SD card review up! Controller, Stylus and Cover will come in a all-in-one-review in XYZ days.
[Shield Tablet General] Techamazon:
Figured I'd bump for the sake of updates. There's currently no Shield Controller support on any Custom ROM, even DU which is AOSP based. It shouldn't be that hard to port the dependencies required to make it work though... I'll have a look at it when I have time but my Android dev experience is pretty limited, but I'll do what I can.

I've also updated the review section which is found on post #3, while adding more nifty stuff to post #2 so give it a go. ;)
[Shield Tablet General] Techamazon:
Huge bump on TWRP. You can find it here (twrp-3.0.1-0).

I'll report in a bit on fixes for our device.

update: do NOT flash as it'll reboot when you're trying to access TWRP.

update2: seems it was made for L bootloader.

[Shield Tablet General] Techamazon:
I'm just gonna shout out this warning since I'm not sure where the current issue is and frankly tracing it isn't exactly fun.

Any custom ROM (like the ones mentioned in post #2) have issues with the screen.

From what I can tell; there's screen flickering, which is very noticeable on white background.

Second of all is that this issue also keeps going on even if the screen is turned off. This leads to a very low standby time of <12-32 hours in my case. I've tried different things to try and trace the real issue at hand but come up empty handed, but my guesstimate is that it isn't kernel related at least.

Stock has no issues (in my case) as the standby time is very close to my N7 2013 which is 4-6 weeks.

My best guess would be that the ambient sensor is borked (ROM/lib wise) since even with adaptive brightness turned off it still keeps acting up.
[Shield Tablet General] stab244:
Does this work properly with adoptable storage?

EDIT: Decided to flash it anyways. Nope it doesn't work with adoptable storage still. Doesn't detect the microSD card. But it does work for other stuff. I just have to use an OTG drive to flash files since I can't seem to access internal storage anymore in Solid Explorer to put zip files.

Yeah. I read some devices got decryption of adoptable storage supported in TWRP 3.0 but I guess this device wasn't one of them. BTW the latest beta for SuperSU works with the latest update (v1.2). I didn't try the stable SSU.

I really hope they ditch AOSP keyboard in the April~ update as they have Google Keyboard as well and they differ very little today (AOSP having slightly less functionality). From what I can remember, AOSP and Google Keyboard branched together and then split sometime when KK was a hot topic and times have changed... so don't leave anything there when a superior version is already included (Nvidia if you are reading this)!

This will cause less confusion among users not to mention having one app less to purge.

Then there's the fact that you can pre-install insert app here in /data (I'm looking at you Fallout Shelter), I mean we saw what happened to Trine 2.

It looks like your flashing the newest k1 update on an og shield. If i remember right the system is a different size and you can't flash the k1 image because it is larger than your partition.

Hey all - read through the thread and bits and pieces here and there from various threads, but not sure I have this all straight... I just got a new K1, it's on 5.1.1 and says there's an OTA available. I've read around that several folks said it's not necessarily a good idea to upgrade to 6.0. Is that still the prevailing wisdom? If I should stay on 5.1.1, then basically the drill is to fastboot oem unlock, flash twrp 2.8.7.0, and then supersu from twrp, right?
