I have the original LTE model.
[Shield Tablet Android Development] Triodexe:
I have the Shield K1 without Lte so could be that Icera didnt work right and hard for me to fix this

are you able to get a boot Logcat and Dmesg and can send it to me maybe error is loged there inside .

Greats Triodexe
[Shield Tablet Android Development] ModSmacked:
Installed on my K1 without issue. I didn't know it was capable of running this fast. The only thing I've run into so far is Google Maps on first boot it complaining about it not being installed correctly and that it needs to be reinstalled. Thank you for this ROM.
[Shield Tablet Android Development] Triodexe:
Hi

Yes the Shield runs smooth with this Rom The Google Maps error could be that your Gapps are little old.

Working on new Version hope to get Netflix HD running Atm it shows Widewine Level 1 support but i only hear the sound and no picture guess there is a problem with the Keystore cause Crypto runs.

Btw to get Netflix app from the Playstore you need Magisk with the Props Modul to change the Build Fingerprint and currently the Liboemcrypto Fix to get it play in SD Quality.

Nvidia Games now starts too without errors but right after loading game it crashes.

Ah and the new Version will come out first with Stock unmodified Kernel need to find out what exactly causes the random Bootloops.

The Quickcharge 2.0 Dtb Mod still works with the Stock Kernel its so nice to see the Shield charging in 50 Minutes to full and the Battery didnt go empty anymore when heavy Gaming :)

Can anyone verify if they have ethernet working on this ROM?

I have a micro USB to USB adapter then a USB to ethernet. I know it has worked before. I haven't tested in probably at least a year. Just seeing if I need new adapters.
[Shield Tablet Android Development] Triodexe:
Hi

Cant help you with that didnt have such a adapter and dont know if it needs kerneldriver support

I have one of these but don't think it works. I didn't try it, but I did try my shield controller connected with OTG and it was not recognized. Works on LOS with the same OTG cable.
[Shield Tablet Android Development] JPX87:
Hello,

I just flashed the ROM and it works, apart from some bugs like the camera (as said in the description), the audio (loss of quality in a rare way) and the video on youtube but that after restarting youtube the bug was not there.

But I don't mind the only thing I miss is the shield applications like "shiled accessory" for the controller as well as the others because my controller has become unusable.

otherwise thank you for this great ROM hoping to be able to install these applications.
[Shield Tablet Android Development] amanguver:
I have also installed the ROM (with zram, no dtb) and it works fine for the most part but I'm facing the "low quality audio" issue too. Same thing happens with Lineage OS 14. It is most noticeable on games like Battle Bay or Brawl Stars... If you compare the audio between the stock ROM and this ROM it's not the same...
[Shield Tablet Android Development] Triodexe:
Add Info

Hi

For the Controller i tryed it right now with a PS4 Dualshock Bluetooth Controller and everything working wish only Nvidia Games would work :)

For the Audio and other things currently i try to get the Vendor Files from Lineage16.0 compatible

For the Netflix problem there is still a problem with 264.secure decoder tryed so far all avaible Omx i found

but none of this one works with Netflix.

Maybe when Steel01 is further in his development with Lineage 16.0 i find a way to get this working

New Rom is soon on the way when my changes are stable :)

[Shield Tablet Android Development] FLEXITRON:
Hey Guys,

what version is "faster" for daily use (websurfing, instagram etc.) Z-Ram or no Z-Ram?

Thanks!
[Shield Tablet Android Development] Triodexe:
Hi

Rom without Zram is faster and battery drain and cpu usage is little bit lower

but multitasking is not so good without Zram Apps in background closes more offen then

And my feelings are the Zram Rom runs overall smoother and didnt lag when Filecopy tasks in background.

Btw New Rom comes tommorow optimized the Kernel and Camera works now too :)

So only Nvidia Games and Netflix in HD didnt work right but with Props Fingerprint mod and Liboemdecrypt from Magisk you can download Netflix in Playstore and it runs in SD without problems.

For the Netflix problem in HD i didnt find a way to fix problems could be Widewine/KEystore or Overlays from AospExtended cause the sound plays nice only Video is black.

Will Try to build a LineageOS 15.1 Rom with my Vendor/Device/Kernel files to see if Netflix runs there

Maybe some more experienced Dev. could help me with that :)

[Shield Tablet Android Development] FLEXITRON:
Downloaded and tried the new version.

Flashed stock nv-recovery-st-wx-na-wf-5.2.0 for nvidia shield tablet, flashed TWRP, wiped everything except sd card and then flashed the ROM and 8.1 mini Gapps.

Stucked on AEX Bootlogo for 15 minutes :/

Any ideas?

Should I allow the stock ROM to boot up one time before flashing twrp and the new custom rom?
[Shield Tablet Android Development] Triodexe:
Hi

Did u use Twrp 3.3.1 and whiped cache/dalvik after flash ?

Greats Triodexe
[Shield Tablet Android Development] moviefirst:
Flashed the latest ROM with zram, and everything is running just fine for me. I'm definitely experience better battery life.

Thanks for this ROM Triodexe! Great work!
[Shield Tablet Android Development] amanguver:
Hi, how does one update to the latest version? Just by flashing it on top of the old one? Or do I have to wipe everything?
[Shield Tablet Android Development] Triodexe:
Hi

You can Hotflash over the Old Version :)

Only Wipe Cache/Dalvik after that

Greats Triodexe
[Shield Tablet Android Development] FLEXITRON:
Triosexe,

I repeated the steps an everything works flawless.

What Kind of Voodoo magic is it?

In comparison to the modded Stock Nougat with custom Kernel the Speed of this rom is breathtaking.

Why is it so fast? Just because of the new Oreo? Better Kernel? I really would like to understand, what you did there... Maybe in simple words :D
[Shield Tablet Android Development] amanguver:
Yeah, I'm really impressed, my tablet has never been this fast! And the battery is very well optimized too, it no longer lasts 1h:30 like on the stock ROM ?
[Shield Tablet Android Development] Triodexe:
Hi

Its a mix of two first Oreo is faster not my work, but second i did optimized the Kernel and tweaked the Init Files the new Schedulers did the rest .:)

Btw with my standard Settings Rom is optimized for Battery Life.

When you need more Power change to Tripndroid/Interactive with Tripndroid/Zen/Sio Scheduler and Cpuquiet to balanced, but be warned Performance is incredible and Battery drain too :)

But since QC2.0 working with the Dtb its no problem Charger still charges the Akku when on heavyload with only 2,5 Degree more Temp on the Battery :)

Already working on New Version compiled with Sabremod5.1 for the Rom and Archi5.1 for the Kernel when all tests run well i will release them soon .

Greats Triodexe
[Shield Tablet Android Development] xconwayx:
I was looking in the settings on the device, not finding where to modify the kernel settings. Is there a place built in or do you recommend a specific app?
[Shield Tablet Android Development] Triodexe:
Hi

Best is using Kernel Adiutor from playstore

You could manually edit the init files in system folder but thats more complicated :)

Theese Files are needed to modify init.t124.rc and init.tn8_common.rc

The changes i do inside the kernel you cant modify :)

Greats Triodexe
[Shield Tablet Android Development] Triodexe:
Hi

So short Info on LineageOS15.1 Netflix works in HD so there must be some difference to the Aosp Drm handle or Framwork/Overlays.

Try to fix this but since AospTeam didnt update the sources anymore i need to manually copy/modify the Files from LineageOs

Hope i get it fixed soon

sorry i've been out of this for awhile. I did some custom rom thing a long time ago on my shield so the OTA no longer works. Where can I find a stock recovery to flash so i can be on latest firmware (as directed) before flashing this rom? thanks!
[Shield Tablet Android Development] Triodexe:
Hi

Here you go https://developer.nvidia.com/shield-open-source

select the right Recovery Image let it boot one time then reflash Twrp3.3.1 and then you can flash Custom Rom

Hello, first off I'd like to thank you for your continued support of this amazing device, it seems nvidia gave up quite some time ago even though they're still incredibly capable machines.

I'd like to ask, what models of shield tablet is this targeted towards? I tried to flash this on my OG shield 32gb with LTE (Worldwide 5.4 nvidia stock) and even though it could see the network my sim card was on, couldn't see that the sim card was inserted. Am I doing something wrong? I've reverted back to my 5.4 backup for now but will be trying your builds again in the future for sure

Once again, thank you for your time Triodexe

[Shield Tablet Android Development] LouMinartey:
Oh awesome, I'll give it a spin and let you know how I get on, will report back within the next hour or so. Once again great work!

EDIT: I tested the zram enabled version of 29th feb build (todays upload) and it seems I still have the same problem (showing network but not registering simcard inserted). Is there anything I can do to help pinpoint the cause? I can send a logcat if it'll help

For reference I did the following:

Wiped Sys/Data/Cache/Int

Flashed ROM zip

Flashed OpenGAPPS Mini ARM 8.1
[Shield Tablet Android Development] supertory:
Can I dirty flash from a zram variant to a non zram variant ? I'd like more battery life as I think something's wrong with my shield's battery
[Shield Tablet Android Development] Triodexe:
Hmm you could try enable/disable Airplane mode and see if it register then or try out switching from LTE to 3G 2G and Enable/disable Data Roaming cause if you see the Network its a problem with registration to your APN .

More options to fix you can see under DeveloperMode.

Did you tryed remove/reinsert the Sim ?

Logcat could help when the Error is loged :)

Greats Triodexe
[Shield Tablet Android Development] LouMinartey:
Reflashed non-ZRAM version this time to see if that had anything to do with it;

Tried reinserting the SIM card first time as some of these tablets have a defect where the simcard isn't detected after suffering a knock but that wasn't the case as it always fixes after reinsertion.

Can confirm toggling airplane mode doesn't fix, after toggling airplane mode the network name disappears and is replaced by 'No service' for 20 seconds, before returning to the 'No Sim Card - NetworkName' status.

Also all mobile data and mobile network related options are greyed out for me, so I'm unable to go in and pick different network types.

I was also unable to find anything to help in Developer Options. I can attach a logcat but the file is over 5000 messages long, and contains multiple errors (one that stuck out was related to GMScore)

Once again, thank you for your assistance
[Shield Tablet Android Development] WilderSu:
Flashed it on K1, works very well, with DTB flashed QC 2.0 worked of the bat giving 2600 mA, with my fairly recent Aukey and Anker chargers.

It doesn't even get hot surprisingly.

Basically gave it a new life, before it was charging slow as ****.

Thanks!

One thing that I've noticed is that it seems to throttle during quick charging and becomes quite unresponsive to the touch. Is it normal?
[Shield Tablet Android Development] Triodexe:
Hi

Hmm didnt noticed that for me it still runs with good performance on Quickcharge

You could try to change the CpuQuiet from runnable to balanced with Kernel Aditutor

Greats Triodexe
[Shield Tablet Android Development] Darkside281:
I have always found the touch screen is less responsive when charging on any rom.
[Shield Tablet Android Development] WilderSu:
It's quite annoying, typing becomes infuriating. Did anyone investigate this, is it a GPU throttle, CPU?

Does Wi-Fi range/power have any relation to QuichCharge? Or I'm seeing things? It seems that it's more likely to kick in on with WiFi turned on and max signal, which is just weird....

In summary its reliability is worrying.

Edit. QC is definitely tied to signal strength in my case, it only kicks [ 2600 mA ] with full signal, not if WI-Fi is off, otherwise it below 600mA

Does anyone have any idea what's going on?
[Shield Tablet Android Development] WilderSu:
Smartmax seems to be very inefficient, spends a lot time in max state without any graduality, plus gpu was locked into perma max state [ min was set to max ] which burned through battery really fast. Changed some stuff, we'll see how it goes.
[Shield Tablet Android Development] Triodexe:
Hi

Changed the Smartmax Io is busy to 1 and ignore nice load to 0 to get good mix of performance/battery

change theese two back too IoBusy0 and Ignore Nice to 1 for more batterysavings but then Tablet starts to lag in heavy Load Situations

Btw the Gpu Display in Kernel Aditor is not right the Gpu ramps not so much like you said

under Normal Load i reduced max Gbu Clock to around 380 only on Heavy Load it ramps up to 850

Greats Triodexe
[Shield Tablet Android Development] WilderSu:
It seems to have more problems, it doesn't go into deep sleep with smartmax in my case, with ondemand it does, I'll test around.
[Shield Tablet Android Development] Triodexe:
Hmm i didnt have this problems with smartmax 96% deepsleep for me overnight.

You should look if there are any wrong Alarms or Wakelooks prevents the Tablet goes into sleep.

You can set a sensorblock for apps in Aosp Tools that could help.

Greats Triodexe
[Shield Tablet Android Development] WilderSu:
Yup, my mistake, one of the apps was holding it up. I've applied the smartmax changes you've mentioned and it seems to be running fine for now.

The last remaining odd thing is that QC seems to be related to wi-fi and signal strength, when it's low it doesn't do QC, is the Wi-fi so power hungry, inefficient?
[Shield Tablet Android Development] Triodexe:
Hi

Yes Download and Save on Storage is most hungry think on the Tablet when i do Downloads with 5G and around 6Mb/s Powerdraw is around 3000mA but even in this situation my Qc2 Charger charge the Phone with around 500-1000Ma. compared to -500- -1000Ma Drain without QC2.

BTW Quickcharge2.0 on our Shield Works with 9V 2500mA so Max is 20 Watt Charge Capacity and under HeavyLoad Powerdraw is 4V 3500mA 14 Watt little Lower then Stockdraw cause ov the Underclock of CPU and GPU i Did.

Maybe i could tweak this a little bit more so it charges higher on Heavyload but the Risk to Blowup the Battery is to high for me :)

Greats Triodexe
[Shield Tablet Android Development] WilderSu:
nvidia seriously borked something here.. just sayin'

I've got another question, which TWRP are you using? stock doesn't have f2fs as option, does this ROM use sdcard-fs by default?
[Shield Tablet Android Development] Triodexe:
Hi

I use Twrp3.3.1 and yes SdCardFS is on by default no really need for F2FS Atm the Performance of SdCardFS is really Nice i got on Adopted Storage with Sandisk Extreme Pro 60 Mb Write and around 80Mb Read :)
[Shield Tablet Android Development] WilderSu:
Thanks! good to know that I won't have to bother with F2FS.

And just to be sure, Shouldn't the WI-Fi situation be considered a bug? I don't think that any device that I've ever owned had such drastic power draw spikes due to it

Any improvements on 6.7?
[Shield Tablet Android Development] Triodexe:
Hi

I dont think the Wifi is the Problem guess the flash to the Nand takes lot of Power

For the 6.7 not really its Experimental Build to see what is running on Pie

5.8 is more stable. ;)

Greats Triodexe
[Shield Tablet Android Development] WilderSu:
In my case, The QC drops without any transfer or writes, just with signal drop. So I'd still argue that it's a WiFi issue.
[Shield Tablet Android Development] garethj7:
Hi I was just wondering if anyone could help me please? I am trying to revive my Original Nvidia Shield Tablet Wifi version with TWRP 3.3.1 installed, but I just cannot get this ROM to boot it just loops, I've had Lineage 15.1 and 14.1 on it before so I think I'm on the right firmware I just keep getting bootloops.

Hi all,

What is your recommendation? I using the Stock 5.4 Rom and I'm thinking about to go on with Lineage, but then I can't use my Shield Controller and Gamestream anymore, right? BTW Gamestream is too slow to have fun with the games...

Is it possible to use Multirom with a Stock Rom and this 5.8 together?

How is the performance?
[Shield Tablet Android Development] TheKicKer69:
hate to break it to u but not a single Custom ROM for the shield will have ur Nvidia Controller working - that's why i sold my controller! just so u know and no u can't have 2 OS on an Android device
[Shield Tablet Android Development] migo1979:
Hi, I have already installed a multi-rom twrp and installed the stock as internal+and 2 other ROMS. Only the internal works with magisk root for the other ROMS SuperSu is needed to get root access. I was not able to install a ROM on an external SD but on the internal SD it works. What I observed is that I must remove and insert the SD to see the content of the external SD card. That means that this is probably a bug of multi-rom twrp for Shield tablets...
[Shield Tablet Android Development] fernseher:
No posts from dev for weeks - is this rom dead?
[Shield Tablet Android Development] xanthrax:
Most probably he is busy with his real life and if we look around we can see plenty of reasons that may keep people trapped somewhere. Secondly there are those bugs mentioned several times here that are hard to deal with.

For now, this rom provides what we have expected, a better experience than the stock, of course, with some compromises.

I'd have not said "is this rom dead?" instead, "thanks for your hard work so far, wish you well and to be strong enough to provide us with some more"... sounds more encouraging , don't you think?
[Shield Tablet Android Development] AngryCoffeeTable:
Finally decided to root and flash my K1 this morning. Tablet is working just fine and feeling so snappy and fresh after how Nvidia left it. But for some reason, despite multiple flashes & attempts at side loading. I still never had root after installing the new ROM.

What am i doing wrong?

::EDIT::

OK NVM - I done goofed... I was using an older version of supersu from a guide from back in 2015 (beta 2.71) Ive now sideloaded the correct version (2.82) and everything is gravy.
[Shield Tablet Android Development] jemail:
Try Magisk an open source up to date root solution.

You can find it here on XDA.
[Shield Tablet Android Development] AngryCoffeeTable:
So far this has been working well. Except I have noticed that my tablet has a habit of powering itself off completely or randomly rebooting itself once in a while. The shutting off happens if i maybe leave it untouched for a few hours and the reboots just happen out of the blue.

When it restarts it will either spend a super long time at the Nvidia screen or the AEX animation screen. Doesnt always happen but once in a while it does. Not sure if this could possibly a kernel issue???

Good day! Newbie here. How do you flash the .dtb file? I already typed in on the cmd (fastboot flash dtb tegra124-tn8-p1761-1270-a04-e-battery.dtb) and it only says it is waiting for device
[Shield Tablet Android Development] TheKicKer69:
why not flash it thru TWRP? a lot easier - just install it from recovery

[Shield Tablet Android Development] lucifero13:
It did recognize my device using the "fastboot devices".
[Shield Tablet Android Development] TheKicKer69:
then the zip is corrupt. maybe u used a download accelerator or something
[Shield Tablet Android Development] yrp888:
Agree, this ROM has been a breath of fresh air for my K1, especially the deep sleep battery life.

My random reboots are different, I'll sometimes grab the tablet in the middle of the night and find it sitting on the TWRP screen, so it has rebooted to recovery. Not a battery % issue, last night TWRP reported 30% battery.

I'm fairly OK living with this minor inconvenience considering how much better the tablet is with this ROM compared to other ROMs I've tried. I'm even tempted to replace the battery!

Hats off to Dev!
