Hi

Its interesting to see how a running LineageOS 16.0 Rom is out for a device thats so close to the normal Shield Tablet. Also those ATAP's are interesting devices with the 4GB Ram they must be a lot more future proof as the Shield Tablet. I think when i would get hands on such a Device i would definitly give this Rom a try.

But until then are there any plans to make this Rom for the Shield Tablet also ?

hats off and THANK YOU to npjohnson!

this is quite amazing, and impressive, all the work done to get Yellowstone back from the dead. Android 9 offers the best of the best , and to me, 10 & 11 seem to be more google than android.

i didnt see these asked , so here goes.

-with LINEAGE, can we read/write to micro SD cards? (this is broken on stock os)

-does the ddr3 4gig of ram cause any bottlenecks? (ddr3 seems outdated)

-i understand the camera stuff is proprietary, so what can we do as a community, to bring this back into life?

-does the micro HDMI port work and/or can we use this to capture HDMI in?

-using TWRP, is it possible to switch between LINEAGE/STOCK ? (after the initial DD to lineage)

-What mods/tweaks do you recommend to LINEAGE and kernel for best performance?

***unrelated but may be helpful***

*the micro usb port on project tango, can and will pull 2.1 amps @ 5volts from a USB supply, but its not common. ( confirmed with meters ) (hundreds of USB chargers, and i have 3 that work for this)

* the TV show GHOST HUNTERS with ZACK... the SLS camera used for stick-figures is NOT a kinnect, and the computer runs linux. the software is a one-off custom build application from there ghost gadget guy (bill c?) i have been searching for years, for this single built application, as it should be capable of running on android.(no luck so far)

--i am not looking to make a project tango into a ghost stick-man device. the stick-man stuff is too far out for me, but the IR 3D live view is one of my favorites and is a very cool tool. (i spent months searching for old project tango APK's and found one that has full real time 3d imaging. ( many of these are incomplete apps)

--has anyone ever found the application ( stock project tango ) that is always shown in pictures ? ( its a graph/block room, with rainbow colors to show real time depth as you walk around )

once again, thank you for building this. its so nice to have speakers that face the user, along with all the other perks of this device.
[Shield Tablet Original Android Development] npjohnson:
Nah, Aaron does 16.0 for shieldtablet - no need to duplicate work.

1. Yes

2. No

3. Write an OSS Camera HAL and finish importing support into the kernel - in other words, don't waste your time, the Camera's on this are crap anyway tbh for modern standards.

4. Yes Micro HDMI works, never tried to capture, but probably works?

5. No, you need to APX flash to go back to stock - it involves repartitioning, so TWRP is a no-go.

6. None, we really tune it out of the box on this device. Changing things will negate those optimizations.

USB Amperage: We don't want to take chances - what stock does it what we will do, use the dock if you want quicker charging.

App you're talking about: Never seen that, sounds interesting tho.
[Shield Tablet Original Android Development] Scavenger87:
Ok thanks that means the 16.0 for the shieldtablet which you can found here : https://updater.oddsolutions.us/yellowstone#/devices/shieldtablet/builds

is from Aaron (Steel01) ? :)
[Shield Tablet Original Android Development] npjohnson:
Lol no but they're built from his service
[Shield Tablet Original Android Development] Scavenger87:
Ok now i get it you build them from Aaron's repo.

Well in any case thanks for the work and keeping those devices alive and i saw recently at the Changes section of your site there's already bugfixes planed for the next update.

Is there any bugtracker available or a different way to help you guys out with logs ?
[Shield Tablet Original Android Development] npjohnson:
not really, no.

Hi

I tried installing LINEAGE-16.0-20201127-UNOFFICIAL-YELLOWSTONE.ZIP but it failed to boot up. The releases prior to that were fine. I was hoping to be able to use mobile with it. Is there a version that supports it?
[Shield Tablet Original Android Development] npjohnson:
Newest one - try that.

You have a shield tablet - DO NOT use this - this is for the Google Project Tango tablet.
[Shield Tablet Original Android Development] _shagohod_:
Hi

I can use the 1126 build for shield tablet.

But the 1127 and 1210 can't boot 🙁

@lahuze @npjohnson
[Shield Tablet Original Android Development] Scavenger87:
Hi

The 1127 does work for me on my shield k1 tablet but the 1210 is stuck on a bootloop at the nvidia logo. I tried multiple different installs like updating from the 1127 build, install it over twrp directly, install with the los_recovery ( this one has also issues like no rotation and no touchscreen).

I added here the dmesg.log i pulled with twrp i hope its any helpful.
[Shield Tablet Original Android Development] mprudic0404:
Followed directions perfectly , going from stock project TANGO (android 4) and now i have reached a stop point.

i don't use win10, so power-shell was out of the question for me, but KALI worked great. then i reached this step, ( If you’re on Linux, run ./flash.sh ) tried using 32 and 64 bit laptops (all KALI) with no luck. thankfully its a bat file , so after moving all work to storage media, i was able to run the flash.bat on an old WIN7 machine. success !

after this long FLASH.BAT runs, the tablet boots into LINEAGE with success. Again following what is in the guide, did a wipe, and updated (from lineage recovery) with adb sideload. these all work and tablet reboots, but then keeps rebooting until forced off with the three button combo.

ok..., i take a step back. run FLASH.BAT again, and this time i don't upgrade. tablet boots fine , runs great. until i notice the battery about to die. plugged in tablet to usb charger (micro-B) port and notice no current on my meters. ok, weird.. maybe it charges when powered off? no sir.

the only time the tablet charges is when its in recovery mode. ( in recovery it pulls around 1.75 AMPS @ 5volts )

i have two of these tablets, and am already in motion to restore android 4 for the time being. any ideas or help ? ( LINEAGE disables hardware charging?- PS:i don't have the dock anymore, but i am sure i could make up a 30 pin connector <very similar to apple connector> if i had to, because the 12v source is stepped down internally )

notes:

-tried the lineage SU from the WIKI, makes no change in boot loop or charging.

-tried using a older build 11/27 i think? , still loops after upgrade.

- i know you don't like MAGISK , ( @npjohnson ) but i tried flashing it when it seems like all was lost, no change.. (tried multiple ways with MAGISK, but none worked.)

- i want to turn the project TANGO into a android boombox ( i have high end speakers, amps, wood/fiber for a small yet powerful boom box frame.< i will post pics of final build if anyone wants to see it>

-may i ask, after restoring this to android4, can i use TWRP to install a previous version of LINEAGE? (i don't need Bluetooth or cameras, )

- Nvidia has a tool for DEV's listed on the site, that seems like it could port android 5 to the tango. (i am probably wrong?)

-any ideas why the tablet ONLY charges when in FORCED RECOVERY?

... and can we try using other variations of TWRP over LINEAGE RECOVERY? (this recovery is new to me, so want to run back to familiar TWRP, even being its outdated.)

-is there any version of LINEAGE without GAPS ? (if i use this as a media device, no need for GAPS)

The work you have done to bring this device back to life is awesome, and no doubt , took many hours of efforts. what do you recomend i try doing differently ?
[Shield Tablet Original Android Development] npjohnson:
You have a Shield Tablet - please don't use this or try to use this! You can, and will either damage your device, or brick it.

If you have a yellowstone, post a dmesg pls, if not:

You have a Shield Tablet - please don't use this or try to use this! You can, and will either damage your device, or brick it.

You have a Shield Tablet - please don't use this or try to use this! You can, and will either damage your device, or brick it.

You have a Shield Tablet - please don't use this or try to use this! You can, and will either damage your device, or brick it.

Dock is needed to fast charge - our USB port is WONKY.

If you go back to stock, yeah you can probs use CM-14.1 from hwstar, not sure.

And I can see about TWRP for the new partition map, I'll see what I can do.

And no, I don't have lineage without gapps - you can build it yourself though!

I'm using this : https://updater.oddsolutions.us/yellowstone#/devices/shieldtablet/builds

And this topic is in Shield Tablet.

Is it a bug from the new XDA ?
[Shield Tablet Original Android Development] npjohnson:
Project Tango has no forums of it's own, so we are using Shield Tablets as a home for now.

Additionally, the shiledtablet builds you linked are unsupported test builds - there will be no support provided for those.
[Shield Tablet Original Android Development] Scavenger87:
Ok i think we just wait for the next build then maybe its working again and have some more bugfixes
[Shield Tablet Original Android Development] _shagohod_:
Ok, now I understand.

Thanks.
[Shield Tablet Original Android Development] mprudic0404:
is it possible to relink the previous builds for the TANGO? tried 11/27 & 12/10 , but cant get them to fully boot. (i noticed you have a few more files DTB.img , boot.img. would flashing these AFTER the 12/10 version prevent a bootloop?
[Shield Tablet Original Android Development] npjohnson:
It was a bug on my end - I fixed it, newest build boots fine.

Enjoy!
[Shield Tablet Original Android Development] mprudic0404:
could you possibly send me a LINK ( or email? ) to a build before 11/27/2020 i cant seem to get any new builds 11/27-UP to boot?

does anyone have the version before 11/27 ?
[Shield Tablet Original Android Development] mprudic0404:

12/18/2020 - UPDATE -- so if anyone else has this similar issue, running the FLASH.BAT scrip again restores device to the first step in LINEAGE, don't push ANY UPDATES, instead under options, go to system updates, and auto-install the DECEMBER 16 update package. This works and works amazing.

following the guide, i kept trying to UPDATE over ADB-SIDELOAD, but had no luck.

QUESTION to

npjohnson

- SAILFISH OS , ( which i have never tried ) has some method in the building process , that "forks-up" propitiatory components , to the newest OS version. again, never used this OS, but my question is, might this offer a way port the camera ?

-PS- trying my hand at a lineage build , with no google, for my speaker project.

your work on this yellowstone tablet is freaking awesome. THANK YOU

Update on "dead" Tango

ok my issue "seemed" to be the wonky USB port i tried several times to get it going and sometimes it would cut out at the beginning sometimes ibn the middle of flashing the persist.img and sometimes it would complete persist.img and cut out on persistbk.img finally tonight i had some free time and tried again on 3 different computers, same problem.....so i pulled out dock to see if that would connect and of course it doesn't register the docks usb port so i left it in dock and plugged it in and successfully flashed everything!!!! Yay!!!

now i only get a dead battery icon and it wont boot into recovery or connect to PC.....leaving on charger to see if maybe battery was dead but i saw someone else write about dead battery icon (and i haven't read the whole thread)

UPDATE: Success!!!! booted up after 10-15 minutes on charger guess maybe the battery wasn't charged (it had been on usb charger for awhile both before i started and while connected to PC) anyway it's fixed!!!!!!

UPDATE 2: So i tried updating through USB while charged at 90% not on dock and it kept failing so i put it on dock and presto...even if the dock doesn't connect to PC i am assuming this is some "power interruption" or something? I dunno but it's flashed and up to date, so if anyone else has failures when writing while in fastboot/recovery put on dock and it goes through
[Shield Tablet Original Android Development] mprudic0404:
may i ask two questions about the dec 16th build?

1- charging by USB MICRO stops working after installing this update. what changed in the update?(weirdness part, if plugged into a QCS 3.0, starting from a cold boot, it charges for the short boot moment then stops just as the LINEAGE logo transitions to home screen. -- wont charge when off, and wont charge when on, only this short window from boot)

2-under display , themes, the green color if selected, turns everything blue?
[Shield Tablet Original Android Development] akw701:
I have a similar experience to 1. Last full charge 3 das ago, which corresponds to the finaly successfull update to linageOS 16. I used the dock and several power supplies. I tried also to switch to recovery for charging, which was mentioned before in this thread. Did not work for me. The battery symbol changes sometimes when I unplug an replug the powersupply either dock or micro USB.

I am down to 15 minutes display time (63% accu capacity) which also is wired.

I just retried and I booted into recovery: it fast charges now in 15 Minute from 61 to 93%

2-The Display I can not verify. Green works fine one other color too. More I will check later.

Otherwise LOS16 works fine so far with this limited power capabilities. Some severe hurdles to pass until I got here :)

Anything I could do to help on the power issue?
[Shield Tablet Original Android Development] mprudic0404:
using a ROOT file explorer or ADB, (which ever works best) anyone know if its possible to copy the files used for charging on stock 4.4, and paste them into LINEAGE16? (not folders, just a few files) ( i am asking this question too- these files are for OFFLINE charging, as dosent the KERNEL handle charging when powered on?)

i was randomly digging around with a file explorer in VIEW ONLY and found the folder which contained the POWER OFF charging animation, but couldn't find the associated files for charging. (i have not looked at the first LINEAGE16 IMAGE, just the DEC16 update)

doing the same digging on the stock 4.4 , makes one really appreciate the work done to get this tablet up to date.

i belive its dangerous to add/move files around while the device is running, so to properly add/mod anything would be best served to DL the 16th build and adjust that, before re-signing it, flashing it.
[Shield Tablet Original Android Development] harrison-matt:
I have been following the wiki install steps and when I attempt to "make it ra1n" using towelroot v3 it reports that "this phone isn't currently supported."

Is there another way?

Can I continue the install steps without root?

Please advise.

Additionally, I am attempting to update my device to turn it into my family's entertainment for a trip where we will not likely have internet access. I am hoping I can after updating to this ROM install Disney+, HBO Max, etc So, a couple of questions:

Anyone experience any issues with accessing or video playback on these apps:

Netflix

Disney+

HBO Max

Hulu

Amazon Video

etc.

Does the micro HDMI work well for watching videos?

Your thoughts and experience are appreciated.
[Shield Tablet Original Android Development] wywerny:
Thank you for the latest update
[Shield Tablet Original Android Development] ryanbg:
I will look into this. The drivers for the charger and the external connector (dock charging component) were written for 3.4, and the driver is SUPER hacky. I had to port it to 3.10, but it really needs a clean rewrite to play nicely. The tablet has a pretty high power budget and often the MicroUSB port might not be able to provide enough amperage while the device is in use. The NVidia charging code is somewhat cryptic and it takes a while to reverse what is actually going on. There's some odd behavior with the interrupts handling switching between USB and the dock for charging. Inside the charging IC there is a switch to enable 12V input (charging via dock), and sometimes this can get into an inconsistent state. There's technically TWO batteries wired together as one battery that requires a higher voltage (~8V) than say your typical battery which is usually running at 3.7V.

Part of the problem is that in order to use 3.10 effectively (Secure Storage, some DRM stuff, etc...), we need ARM PSCI support (especially if we look beyond 3.10 in the future). TN8 (Shield Tablet) received this while Yellowstone was still stuck on Trusted Foundations TEE. There's a handful of binaries that use some of the newer TOS functionality as well.

I had to kang the TN8 early bootloader (nvtboot) in order to load the newer PSCI-compatible TOS (TrustZone image) according to the newer mechanism (Yellowstone OEM bootloader doesn't support this loading mechanism). One problem is that the TN8 early bootloader doesn't support the charging or battery ICs on the Yellowstone, so the chips come up from boot in an inconsistent state that needs to be cleaned up by the kernel.

I did come across a more recent TOS image that was released for Yellowstone that fixes some of the off-mode charging and standby/sleep charging, but it still doesn't address loading the PSCI TOS image correctly. I had to reverse engineer both bootloaders and do some patches to make it play nicely with the newer kernel as well. It may be possible to embed the TOS loading code into the Yellowstone early bootloader, but this is extremely tedious and time consuming and requires extensive testing.

I did start writing the PSCI code from scratch in assembley for their PSCI implementation so I could have u-boot replace the early stage bootloader, but it requires a significant amount of effort and intimate knowledge of the hardware. I simply don't have the time to do so.

I took a hiatus from programming about a year ago because I had spent about 18 months working on this device non-stop and other security research work and burned out. It wasn't fun for me anymore and I didn't have as much time. I will have a bit more time now and the will is returning so I am hoping to pick up where I left off.

the latest update Github link is not working.

appreciate your work👍👍👍
[Shield Tablet Original Android Development] mprudic0404:
thank you for your time and efforts, its such a unique device.

may i ask a question, ?

how tricky would it be , to port a version of the MS software (windows version) onto this device for use with 3d imaging. ( i understand the camera is a RGB, not TIME TO FLIGHT ) they seem to share enough , that it may be possible to have a slightly degraded version of kinnect on this tablet ?

PS : is there anyway i can help you in your work on this device>?
[Shield Tablet Original Android Development] npjohnson:
Had to pull it, it's back up.

Porting an MS Windows app? With no source? hard as hell lol.

The camera will likely never work past 4.4.
[Shield Tablet Original Android Development] akw701:
Did somebody try the lineage-16.0-20211009-UNOFFICIAL-yellowstone.zip build.

After the second reboot, the first worked seemingly well, the boot process stops after displaying the first lineage logo parts.

The battery symbol that is displayed after pushing the power buttom again, always displays a full battery, something that occured seldom before.

pushing volume + and - and power to get into recovery does not work.

Any idea what to try to get it into recovery mode?
[Shield Tablet Original Android Development] npjohnson:
hold all the buttons to reset it. But yeah it works, I updated my ys myself to that build.
[Shield Tablet Original Android Development] akw701:
Did this for several times.Battery symbol showed always 100%. After approx. one hour of repeated tries the symbol changed to empty battery. I charged the tablet in the dock. The next morning the boot of lineage worked perfectly.

So for me the main issue remains, that the power managment is not working properly.

Right now it still shows 100% even after one hour of continous use.... I expect the tablet to switch off all of all of a sudden.

Did you work on the power management lately?
[Shield Tablet Original Android Development] npjohnson:
Sounds like your device is having some issues with the fuel-gauge sensor - my tablet with YouTube open just ticked down to 90% over the course of 40 min watching videos.

Hello, I recently found a bunch of these tablets at work and have been trying to get them running again using lineage. I have followed everything I can find and I am running into the error 7 because I have not repartitioned.
