Thank you sir for what you did while you could.
[Shield Tablet Android Development] Scavenger87:
Thank you for your work to keep this great Rom updated its sad to see it go now because for me its still the benchmark of a good working and fast Rom for People that just want to use this Device as a normal Tablet
[Shield Tablet Android Development] :
Thank you very much!
[Shield Tablet Android Development] TheKicKer69:
Tx man i will keep using the latest 15.1 Build for my shield! u did help tons by creating this ROM. Cheers, Roger
[Shield Tablet Android Development] yrp888:
Has anyone managed to flash this fresh recently?

I had reason to wipe my K1 that has been running the 14.1 20201101 build since end of last year, and while I can flash 14.1 20210610 or 20210312 with latest GAPPS, and it boots up fine, after I connect to the WLAN it sits at the "Checking for updates..." screen forever (like over an hour) without progressing.

Full Wipe in TWRP, everything except External SD.

I've looked at the WAP and router, watching the traffic stats and after an initial burst of W activity it stops with basically no traffic flow. All other WAP devices access the internet just fine.

I want to keep using Saint2k's ROM on my K1 as it has been the most stable and responsive one I've tested.
[Shield Tablet Android Development] Scavenger87:
Just skip the part with the wlan connection and login into the playstore and do it after the setup wizzard and you should be fine.

@The-Saint2k

I'm glad you decide to release a another build ;)
[Shield Tablet Android Development] yrp888:
Sorry I missed this, I was in a bit of a dilemma and ran up AEX which sailed past the "Checking Updates" screen.

If I have to retry loading up this ROM now I know the trick, thanks for the tip.
[Shield Tablet Android Development] narflynn619:
I know I'm being stupid but I can't seem to flash the 14.1 zip on my tablet via TWRP. It's been a while (like 3 or 4 years) since I flashed a device of any kind. Tablet is currently updated to 5.4. I'm getting this error (see picture):
[Shield Tablet Android Development] tissot:
Are you running on latest twrp?
[Shield Tablet Android Development] narflynn619:
Most likely, no. Been a while. So need to use which version of TWRP?
[Shield Tablet Android Development] moonhop7:
The picture looks like TWRP is fine but can't install the zip package because it's incomplete or the wrong version .
[Shield Tablet Android Development] ogremalfeitor:
It's just showing that it's incompatible with the data you have. You must wipe your data partition or else it won't proceed. Be sure to backup anything of interest first.
[Shield Tablet Android Development] narflynn619:
Thank you all guys. Apparently it only needs full wipe of data. Installed properly this time. Now I'm having problem installing GApps. Which version do I need to flash? It keeps giving me "corrupted zip" on TWRP.

EDIT: Disregard, folks. I ended up installing Pico version and it installed fine. I only needed access to Play Store. Thanks everyone!
[Shield Tablet Android Development] nunitofiman:
I have just installed lineageOS 14.1 versión 2021 and I can say that it is the best rom.

14.1 FIx Wifi: Go to the router and in Type of client allowed WPA (+WPA2) in the connection
[Shield Tablet Android Development] BellerophonM:
How bad are the effects of the lack of hardware acceleration on this when compared to the stock rom? Is it something I'll notice when using it to watch content?
[Shield Tablet Android Development] moonhop7:
Download the rom from Nvidia Gameworks Developer (Extract in folder)

While in fastboot mode:

fastboot flash recovery (drag recovery)

fastboot flash boot (drag boot)

fastboot flash system (drag system)

fastboot flash staging (drag blob)

fastboot reboot

These tablets are very difficult to hard brick . If the the tablet can be seen, you can reflash the firmware. The battery is also soldered to the board. If it is not able to be fixed by this, search XDA for "Nvidia Shield APX Mode Fix / Brick "
[Shield Tablet Android Development] ITA-Berserk:
Hi everyone, i decided to go for a custom rom for my Shield K1, so:

- Flashed TWRP 3.7.0_9-0 (everything fine)

- Formatted Data and Advanced Wipe done (Cache and System)

- Tried to flash LineageOS 14.1 via TWRP ADB Sideload and it gives me the ERROR 7

( E3004: This package is for device: shieldtablet; this device is . )

- Tried to flash LineageOS 15.1 and everything goes fine.

I would like to flash 14.1 since i mostly use this tablet to watch videos and i read about the video artifacts and HW acceleration problems in 15.1

Is there a way to avoid that ERROR 7 for the 14.1 flashing?

EDIT:

SOLVED BY FLASHING A PREVIOUS VERSION OF TWRP

(TWRP 3.3.0-0 worked nicely)
[Shield Tablet Android Development] Roger9111:
Hi All. I'm new here but just successfully put a new battery in my Shield K1.

How do I get rid of the notice to upgrade my software when I open the tablet. I had upgraded and it really slowed the tablet down so I went back to the original. I want to disable the notice to upgrade.

As well, could I get any input on what operating system is current? I'll keep searching this forum for ideas as well.

Thanks
[Shield Tablet Android Development] TheToxicant:
So if I read what your saying right this next 14.1 build requires a full wipe to install if your running the july one?
[Shield Tablet Android Development] The-Saint2k:
I'm afraid so. I'm sorry.:crying:

But build 20190803 doesn't contain security updates from August yet, they are not released yet.
[Shield Tablet Android Development] TheToxicant:
Well damn but I guess that's half the fun of a custom OS.

[Shield Tablet Android Development] The-Saint2k:
Hello, everybody,

I have uploaded a current build for the month of August. It contains the latest August security updates. The August update 14.1 will follow as soon as it is completely available (including security string).

Direct Link (August 15.1.)
[Shield Tablet Android Development] The-Saint2k:
It went faster than I thought. Enclosed the current 14.1 build. The 15.1 build from yesterday was still tested, but now I stay at 14.1.

Security Level August (14.1)
[Shield Tablet Android Development] Snah001:
Thnx.

The mandatory full wipe still necessary?

And only for this build?
[Shield Tablet Android Development] Cm4nXD:
It depends on where you are updating from. If from a previous unofficial build then no, as long as it's from the same developer. If you are updating from an official build, then a fill wipe is necessary. You can find your answer in the thread here:
[Shield Tablet Android Development] Vankog:
Hi,

I am a first-time cyanogen/lineage flasher. So I'd like to get to know the tidbits of this particular ROM installation.

Could you state in the first post if this ROM is for all variants?

In particular, I am looking for confirmation about the LTE ROTW variant.

Also, could you point me to the documentation about what the linked "Firmware Update : N/Stock 5.0" is about?

And what to do with it?

After some searching I found this official installation guide: https://wiki.lineageos.org/devices/shieldtablet

Could you please link this in the first post as well?

It is a good starting point for beginner. However, I cannot find specifics in this guide, so these questions remain, I'm afraid.

It seems Magisk can be used. I guess this should be installed instead of the "LineageOS’s AddonSU" mentioned in the guide?

Or is the Addon complementary?

Or what root app/framework do you suggest? (I don't care for systemless on my Shield.)

general questions:

Seeing there are video issues with 15.1 (Oreo, right?), I guess I should stay on 14.1 (Nougat?) for daily driver?

Particularly in the light of using it mainly for my Youtube and Netflix bedtime routine nowadays.

Has anyone tried CF.lumen with 14.1? I need to tint and dim my screen for bedtime quite drastically (especially to not disturb my girfriend) and I couldn't find any alternative to CF.Lumen that isn't just using an overlay. :-/ )

Thank you very much! It is awesome to still see progress for this device.
[Shield Tablet Android Development] Snah001:
Well you thought that I did not know that???

Look at my joining date at XDA so before making such a comment and just check if you're talking to a noob.

Oh and read the statement of the dev but you probably didn't do that.:angel:
[Shield Tablet Android Development] Cm4nXD:
I'm glad you found your answer! Sorry I guess I misunderstood your question. ¯\_(ツ)_/¯

On another note, I don't bother looking at people's profiles, I don't really care how long you've been on the website. If you look at mine you'll see I'm a "noob". Only trying to help you find the answer. I find directing people is better than answering, just in case I'm wrong. ?

---------- Post added at 05:51 AM ---------- Previous post was at 05:22 AM ----------

I believe that this ROM is continued work on LOS seeing as [MENTION=2941722]steal01[/MENTION] isn't updating the official one anymore, and if that's the case, probably? There's a discussion in the official thread about the it being installed on the LTE varient. Try it out, if things go badly, you can just fastboot flash the stock firmware.

The "Firmware Update : N/Stock 5.0" I'm pretty sure that's just a staging blob thing for the bootloader. So as long as you installed the latest version of STOCK Nvidia software (I'm guessing you did because you said first time flashing), you should be fine.

As for root, you can use LOS add-on su, but there isn't really any benefit over Magisk. Magisk has the benefit of passing saftynet, and a framework for mods, so in my opinion it's better than the included root.

I would recommend 14.1 over 15.1 definitely for daily driver. Lack of HW Accelerated Video Decoding is a huge lamo. No Netflix without it. Unless there is a patch to make it work, I haven't found one.

As for CF-lumen, I've never even heard of it. But again, try it out, if all else fails you can always return to stock.

Just make sure to back up your data before you go messing with stuff. ;)
[Shield Tablet Android Development] wgorham:
Stupid question. Does this build still have the Nvidia apps? I am really only worried about having three apps. Nvidia games, Shield console, and Shield accessories I actually use and would hate to lose. Unless someone knows of a better way to stream play steam games on it.
[Shield Tablet Android Development] The-Saint2k:
Super support! :good::good::good::highfive:

I was about to write almost the same as well.

- it's correct that build 20190803 14.1 was buggy, i don't know that anyone could update from this build correctly, so a full wipe is necessary

- the text from the OP is from Steel (I just took it over,sory), but it's correct, the ZIP is not necessary if you were up to date with the stock version

- in the version 15.1 of the HWC buggy therefore Netflix doesn't work for example (I only use the 14.1 version now)

- i can't say if it's compatible with the LTE variant, but i suspect it is. Because on the LineageOS page the specifications of LTE are talking.

You're absolutely right that I only build the image from the sources. I don't make any changes, only Steel or others can do that.
[Shield Tablet Android Development] Cm4nXD:
Shield console mode is included, I believe Nvidia Games & Accessories can be installed via the play store.
[Shield Tablet Android Development] Vankog:
Thanks for the clarification.

However, the device of question is currently still on stock M.

Does this mean I should flash the latest stock N first?
[Shield Tablet Android Development] p3dboard:
If it's on Stock M, then it might be a Tablet that was part of the battery recall, otherwise you should have received OTA Updates to Android 7 (nvidia 5.4 build being the last released).

If that is the case, someone probably removed the nvidia ota update system after getting a replacement Tab from nvidia. If this is true, if you flash a stock nvidia rom, if you don't flash the remove ota script, you could end up with a bricked tablet as Nvidia were pushing out an update to disable any old tablets that were part of the battery replacement program.

Just warning you, so you don't end up with a bricked / disabled tablet.

You might want to look in the other shield forums about getting the nomoreota.zip, to be able to remove the nvidia over the air (ota) updates
[Shield Tablet Android Development] Vankog:
Thanks! It's nice of you for taking care! But the "someone" was me. ;) (Though, the OTAs were not working properly anyway, because of heavy root usage.)

So the answer is: Yes, I have to upgrade first?
[Shield Tablet Android Development] p3dboard:
Yes, to get to the Android 7 (5.x) boot loader / firmware.
[Shield Tablet Android Development] tmacher:
Hello,

I've installed the rom 14.1 and gapps without problem but now I can't enable magisk. I flash it in recovery without problems but magisk manager day it's not installed. Some advice?

Edit:

Ok, I'm stupid... Magisk menager was installed on sd card. After transfer to internal storage it works.

Edit2:

Can dev [MENTION=9451302]The-Saint2k[/MENTION] add offline charging option?
[Shield Tablet Android Development] jemail:
I would recommend Nougat as the most reliable and stable android version for the nvidia shield tablet.

I have used 14.1 with CF.lumen exactly for the reasons you gave, it works with no problems.

I use Vanced YouTube Magisk module with no problems.

I use Magisk latest as my root solution.

I currently use bit obsession's AEx ROM with BitObbession's Bit-O-KX10-003 kernel.

I would switch to the newer 14.1 ROM posted recently on these forums but no OMS support for substratum themeing is currently a deal breaker, bright white screens at night are a no no for me.

I do have a 14.1 ROM with OMS support that was kindly built for me by [MENTION=7929484]MSe1969[/MENTION] from the the Motorola G 2015 forum in February 2019. It works well and I'll probably change to it after the summer is over.

I did ask [MENTION=9451302]The-Saint2k[/MENTION], the developer of the 14.1 ROM here to contact [MENTION=7929484]MSe1969[/MENTION] about OMS support but he/she seems reluctant to do so. A shame really as it's possible to produce a 14.1 ROM with OMS support and current security updates which would be the dream ROM for our device.
[Shield Tablet Android Development] The-Saint2k:
You mean when the tablet's off, it's just a charging screen? Because that works for me.
[Shield Tablet Android Development] The-Saint2k:
Hello, jemail,

it's correct that I haven't made contact yet. There are several reasons for this. First of all, I am still gaining experience. Also, a build environment needs a lot of memory and time. I would also have to test it, which can lead to data loss, which takes time again. In addition, MSe1969 has documented its things well, so I will try it myself. Currently I can only do such gimmicks on weekends, because a completely new build takes 20h and I do it on my business laptop. I hope that excuses it a bit.:fingers-crossed:
[Shield Tablet Android Development] tmacher:
Checked one more time and it works. I don't know why for the first time I've checked the tablet turn on when I contacted it to the charger.
[Shield Tablet Android Development] TheToxicant:
[MENTION=9451302]The-Saint2k[/MENTION] I just updated to your latest build and I must say it runs quite nicely.
[Shield Tablet Android Development] Hack_AR:
I run into some incompatibility. After I downgraded from last official 15.1 to 14.1 from here, the tablet cant connect to one of my routers. Neither 2.4 nor 5 GHz will work.
[Shield Tablet Android Development] Snah001:
That build requires a full wipe mentioned by the dev himself.

Maybe forgot to do that?

Verstuurd vanaf mijn Mi 9T Pro met Tapatalk
[Shield Tablet Android Development] Hack_AR:
Just removed the sd card, went to Recovery, formatted and wiped everything possible.

Flashed the 14.1-20190813 from this thread with pico open gapps, official su addon and TitaniumBackup.

Still, neither 5GHz nor 2.4GHz will connect.

Just installed the 15.1 from this thread. WiFi works.
[Shield Tablet Android Development] Saison2018:
Strange.

I was on 20190803 (full wipe/clean flash) and now my tablet uses 20190813 build (standard upgrade with TWRP) and I am able to connect to 5 Ghz wifi. My router is a Asus AC68U.

Just to share with you another setup (if it could help).
[Shield Tablet Android Development] The-Saint2k:
Now it's getting weird. I now have the same problem myself. I have installed 14.1. and suddenly I can't establish a WIFI connection. But I didn't do an update or anything else, it came suddenly.

I will now test around a bit. But unfortunately I am not a DEV, even if I would like to be :). I just compile everything from the sources. I will install it completely clean. Do any more have these problems?
[Shield Tablet Android Development] Snah001:
I have no problems with WiFi. Both 2,4Ghz and 5Ghz work fine.

[Shield Tablet Android Development] TheToxicant:
No Wi-Fi problems on mine
[Shield Tablet Android Development] The-Saint2k:
The update to 15.1 also helps with me. Since the LineageOs team uploaded the September security updates, I will build the next build tomorrow evening. Then the bug in the 14.1 build might be fixed, although I couldn't find a relevant entry in the changelogs.

So this weekend there will be new builds for 14.1 & 15.1.
[Shield Tablet Android Development] Snah001:
Hope that the 14.1 can be flashed dirty

Hello to all , i installed the 14.1 version , all seems fast and nice but cant connect the controller of shield ? Is there any program i should add ?
[Shield Tablet Android Development] aliveanddead86:
Hey,

You need to use an OTG cable to connect the controller directly to the tablet. I use a micro usb splitter for 2 inputs into the tablet. One goes to the controller, other to a charger.
[Shield Tablet Android Development] The-Saint2k:
Shame on me. Some time ago I activated a security function in my router. Since I don't use the tablet every day, I couldn't find any connection. The tablet has a problem with PMF WIFI. After deactivating it everything works again.

I also uploaded a new build for LineageOS 14.1 with September Security Update. (Download)

September Build Lineage 15.1 comes tomorrow.

Have fun and sorry for the confusion.
[MENTION=9685034]Hack_AR[/MENTION] Search the router for a setting called PMF(wiki) and disable it or use 15.1, but unfortunately without HWC.
[Shield Tablet Android Development] Snah001:
Thanks for the 14.1 with September security update!
[Shield Tablet Android Development] Vishal P:
Will this ROM work on MI Pad, which has the same chipset? We have some ROM's based on shield blobs, but they are not updated anymore.
[Shield Tablet Android Development] The-Saint2k:
LineageOs 15.1 September is now ready for download. Download
[Shield Tablet Android Development] The-Saint2k:
No, I don't think so. If there was a "local_manifest.xml" from one of those who have already built it successfully, it would probably be easy to rebuild it with current sources. But I couldn't find anything on the fast one.
[Shield Tablet Android Development] Snah001:
Flashed 14.1 this morning and dirty flash was succesfull!!!

Thanks again! :good:
[Shield Tablet Android Development] Vishal P:
Where should I look for that file? Can I get it from github sources of existing custom ROM's?
[Shield Tablet Android Development] Saison2018:
Dirty flash latest build over 20190813.

Everything seems OK until now.

Will report back if something happens.

Thanks a lot.

Sources for a building the lineageos 14.1 from scratch

Hey, Can you share the sources and all the required proprietary vendor files needed to build the LineageOS 14.1 for the Shield tablet K1? I can't build the from the guide, it doesn't pull all the necessary proprietary files from either a previous version of lineage rom or its flash-able zip file. It needs some extra files which it doesn't find.
[Shield Tablet Android Development] The-Saint2k:
Pls look at https://github.com/TheMuppets/proprietary_vendor_nvidia. The Rest comes from the lineageos repo.
[Shield Tablet Android Development] The-Saint2k:
This is a Local_manifest of a motoG5. many devs are releasing their manifest (for Shield i dont need one).

Oh okay. By the way, how much time it takes to compile? And what is specs of your pc?
[Shield Tablet Android Development] ocarinaz1:
Hey I am kinda new to this but I flashed my shield tab to the lineage 15.1 rom. I see the September build released recently how do I install this do I need to do a full wipe. And what is the dirty install method? My apologies for the noob questions
[Shield Tablet Android Development] silvershadow:
Thanks for the 14.1 builds!

I had a question regarding 14.1:

At first glance it seems like everything works fine, but after actually reading through this thread, it seems like some things don't work (its not clear if they just dont work all the time, or if they work but that particular user was just doing something wrong). would someone be able to confirm?

- all nvidia and shield apps can be reinstalled and they work as expected

- shield accessories

- shield camera

- shield console mode AND mirror mode

- hdmi out

- nvidia games (including working gamestream)

- nvidia dabbler +stylus works as expected like stock

- gen 1 shield controller wireless (i read OTG wired works)

Thanks in advanced for clearing them all up!
[Shield Tablet Android Development] p3dboard:
Wifi connection for Gen 1 shield controller doesn't work, that requires special nvidia frameworks. You need to use it via usb otg. I am using stock nvidia rom because of this
