[Android Head-Units] marciosilvadesign:
So after a few weeks banging my head over the no-sound issue on my 8227L head unit on a Peugeot 407, I found the culprit: as the car has a JBL sound system - and amplifier - it needs a special cable and harness. I ordered one, it connects to the main stock radio and plugs the android radio and the car all together.

Great, it plays sound, even some stock radio buttons work and transmit information to the android screen, so on.

But now comes another issue: the default music player just ignores the folder structure, and therefore, file naming.

When playing the songs by alphabetic order, it cycles ALL tracks starting by "01 - ... ", then ALL the "02 - ... " tracks, and yada yada. I could correct this in Windows explorer, renaming all the files and placing a "[album name] 01 - track name " method (I have downloaded a freeware that does that renaming process a breeze, so its not too big of a hassle). Also, there are a few albums with 2 or even 3 CD, and that would imply a further renaming like "[album name][CD#] 01 - track name" in those cases.

Or

I could just get another media player for the android unit. I tried 2 different media players and they see the folders without issue (and play the musics accordingly in the correct order). But they don't replace the default music player and there is no option to change it. All I have is an option to set the default GPS / navigation app, not the radio, not the music one.

Is there any workaround for this?

Here are the unit details (nevermind the can information, the current one is Hiworld W25):

Hi,

I'm a french beginner and I tried to update my HTC x7500 to the radio v1.58.

At the screen of my PDA, it display "Loading...", and I can do nothing because the USB connection doesn't work anymore.

What Can I do?

I have already try a hard reset by press Volume down and reset and I have always the same message at the screen "Loading..."

Also I 've forgot to use "AthenaUnlocker.exe" before my upgrade.

Thanks,

Alex

For all models, the 8.2.3 version needs to erase the userdata partition, which will force you to sign back into the shield again. The 2015 pro (500 GB) versions do not have this partition added to the script, so you will need to run factory reset from the bootloader if your flash hangs on the google logo, and that takes a while, this is why this partition was not added to the 2015 Pro erase script, as it never actually completed for me.

Hey ,i have problems locking the bootloader..

Unlocking and installing all above went fine, i choose the 8.2.3 version.

Using the fast boot menu, or adb, both say they locked the bootloader.. but when i go into the android settings, and go to AI upscaling, it still shows me that the bootloader is unlocked. I also CANT find disney plus in the store. means the loader is unlocked.

What can i do?"
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
@tarreltje You are able to flash back the recovery (Stock) images from gameworks.

I will download those now and add them to the OP, the images I originally shared are the Dev Images, so this is my bad.

The dev images are for people using magisk or twrp and that is likely what is still flagging the ai upscaler bc the build props and other files are different.

I will add the images you need and clarify the post and I will tag you when they have been added;

Sorry for the trouble~! But thank you for telling me about the problem
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] tarreltje:
Hey jenneh,

All is working fine now!! Locked bootloader, AI upscaling works, and as expected i could find the disney plus app again in the store!

Thnx for your time and effort!
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
All of the STOCK images have been uploaded and added to the OP along with the missing 8.1.1 dev image. The dev pack all in one has been repacked and reuploaded.

Yes as soon as nvidia releases it on Gameworks I sure will. If its not done by the time I get bored enough and out of a few projects, I can probably pull the Firmware

an edit I was able to pull the firmware I just dont know what to do with it exactly yet.
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] nooted1:
Long time no talk, Jen! You rock, thank you for this! Care to elaborate on the magisk module for upscaling? I will immediately install it haha, I've waited years for something similar.
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
Hi there Noot Noot! I'm not stuck in a fever dream this year I promise! Haha. Tbh I never tried this personally, I had read somewhere that this was possible using a magisk module but idk which or how. Ever since that day you messaged me about trying to figure out a work around I never stopped wondering.

Let me find that link
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
@nooted1 https://github.com/kdrag0n/safetynet-fix this is the addtional module that allowed some users to bypass. I am curious. I will look at it here in a couple hours when I get bored of reading this avb nonsense x.x

Ooo okay I'll give it a shot right now and let you know!
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
@nooted1 Thank You So Much for taking the Time! I really tried to just get you the answer but I could not figure out how to test it myself x.x could you share how you are able to test the upscaler when you are done? Do you just use a certain video of like 1080p or do you use an app? I just really want to understand the tech but I can't without even seeing it in action x.x
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] nooted1:
@jenneh I'm gonna DM you to see if you wanna be part of my Plex, you can use videos from that for testing.

I discovered today you can root the regular non-developer images and it boots without issues; I'm using Magisk Delta (https://huskydg.github.io/magisk-files/) combined with Displax's SafetyNet-Fix MOD v2.0 (https://github.com/Displax/safetynet-fix/releases) and the app YASNAC is reporting that I am totally passing SafetyNet. The Magisk Hide settings need to be set such that everything under Google Play Services is toggled on EXCEPT FOR the GMS one at the top. Also, toggle it on for Google Services Framework.
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
Thank you @nooted1, for making the Shield Fun Again. Haha. This is super interesting, running root on stock. I had tried this on 8.2.3 and got bootlooped. I will check out magisk delta now and play with things. THANKS YOU now all I can think about is going home and trying to root 9.1 x x
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
Well thanks to Noot Noot, we are now able to patch the STOCK images. I was successful in Rooting the STOCK 9.1 image. I've installed Root Explorer, given it Super User Access, and when the 9.1.1 firmware is finishes downloading to the OTA folder, I will get it pulled, then Using Magisk Delta, I can patch the boot.img for 9.1.1 and then we should have full root on the latest stock images.

So a TLDR. 9.1.1 Root method is coming. Just being tested and then I can bundle things up and write something to make it easy for people learning
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] Sage2050:
😲 amazing!
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
YAYYYY It Worked! It Actually Worked! I'm so happy I could cry haha. Gosh. Why couldn't I understand this stuff a year ago?

I will start with the TLDR: We can achieve root on stock in two simple steps now!

1. Run a batch that will erase the original stock boot partition and flash the new modded one

2. Install Magisk Delta APK and Viola~!

3. Optional - Install Safetynet Module ---edit this did not work how i thought it did for the ai upscaler, this is only for APPS stock apps that you dont want to be root detected

A new guide will be made so this one doesn't get too convoluted. On it I will share modded boot.imgs for all the firmwares ready for flashing. As well as a full technical rundown for those that want to know how to do for themselves and give proper credits to our lovely xda community members who helped to figure this stuff out.

Small technical banter for anyone interested:

I was able to modify that boot.img I collected from the OTA update. Then to be absolutely sure it would work from scratch. I COMPLETELY erased my system, reflashed stock 9.0, manually upgraded to 9.1 , then to 9.1.1, then rebooted to the bootloader.

I erased the stock boot partition in fastboot, flashed the modded one, rebooted, and then you have to install the apk on top of the modded boot.img, bc with delta it comes in at version 1 same as the regular magisk, but for me it wouldn't update on it's own.

So I installed the apk which brought it up to 25.2 and after the reset I was able to install zygisk and verify root with root explorer.

One step closer I think to being able to just pull the system with everything preinstalled and or cleaned up / code tweaks / whatever. Idk but I'm gonna try to figure it out. Then we can make roms. Dang it. I want to make roms and I want the community to be able to make roms.

Good night x.x
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] louforgiveno:
Will this method also work on 8.2.3 stock firmware (with ai upscaling working)?

Not sure i like 9+ on the shield....couldn't playback files i could prior to update...even after 9.1.1 just didn't have the patience to deal with it, and 8.2.3 performs better imo
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
I will test it tomorrow and let you know~! 8.2.3 Seems to be what the people on Reddit prefer as well so I will check it out first thing.
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] louforgiveno:
Thank you for your time!

And yes, 8.2.3 is probably the highest I'll ever go....I'm not a fan of android versions beyond android 9.....10, 11 just seem more apple like with crazy restrictions and obstacles to overcome for basic functionality....even my note 10+ won't be updated past android 9 either.....

Thanks again for your work
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
@louforgiveno I feel discouraged towards later versions of android as well. I find it especially disappointing what features vendors are choosing to use, as well as the features they Omit from the new kernels. For instance, why are we not getting the most out of project treble? It is not even implemented on this device. I think I could really go on and on but I find that feature to be the most perplexing to me to leave out, as it was actually really innovative.

Testing some oddities now while testing 8.2.3 I tried this time to use a separate device with magisk installed to patch the boot.img to see if that would work or if the patch has to be done on a shield. I also tried installing the modded boot.img from the start of a new flash. One or both of these two new scenarios caused a bootloop. Erasing, and reflashing as stock, then will test the modded boot.img one more time to see if it is possible to use images from other devices
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
Okay! So you /Cannot/ use another device to make the modded boot.img. I was curious if I could use an Android Emulator, but somehow it causes problems.

Perhaps its the fact that magisk checks device architecture before running and can detect the x86_64 and builds based off that, perhaps there is another element with keys involved. All ends the same.

For best results, build the boot mod on the same kind of device you are flashing to. (note I am building these for us but a note for anyone building their own)

Another build note is, you /Do Not/ need to be on the Same firmware to be able to patch the boot, just a shield (pro 16gb for this example)

I was able to build the modded boot image and get it flashed on 8.2.3, and we have Root!

I am going to completely erase the system again and try to reflash with the new mod added in from the start to see if that works. Then we can figure out the AI bit according to noot noot's steps
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
It looks like everything is working on 8.2.3 and I was able to work out the kinks. You cannot flash the modded boot.img at the beginning, this would have to be done after the system installs. What happened was, everything installed, slowly. However magisk was missing when installation completed.

@louforgiveno here's the beginning of the guide I am working on https://xdaforums.com/t/patched-boo...stock-firmware-and-keep-ai-upscaling.4524873/

[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] Cecillatour:
Does anyone know where are the OTA images located? We could extract the boot image from there, patch it with Magisk (delta) and flash it.
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:
It's located in data/ota_package if you want to obtain the 9.1 or 9.1.1 boot images yourself. Some research notes are here

If you want to save yourself some time I already pulled those files and modded them here
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] Cecillatour:
Thanks a lot! That is the location I also found online but I cannot find it on my Shield. I must be going nuts! I did this once on my old Shield (darcy) but now I cannot find it. I guess I made crucial mistake by installing 9.1.1 full ota without copying it first. After installation it is gone, if I correctly remember. So I guess I will have to use your modified boot images. Thanks for pointing them for me.

I simply wanted to test on my old darcy first before trying on mdarcy.
[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] jenneh:

The dev rooted 8.2.3 has been reuploaded and the link in the op replaced. It was missing the dtbo file. I went ahead and added a modded boot image to it. Steps are the same as stock, install the dev image and you have to sign in, when it finishes installing reboot to bootloader and run bootmod.bat (this is patched with magisk delta. if you want magisk by topjohnwu change the code in bootmod.bat to bootmod1.img and use topjohnwu's apk instead of the one in the zip)

Hello

I want to flash version 8.2.2 stock (currently LOS is running).

Is it correct that I only have to flash the 8.2.2.zip here?

Can I use the following procedure to do this?

I then just use the last section "Installing LineageOS from recovery" to flash the 8.2.2.zip, right?

[Nvidia Shield TV & Shield TV Pro (2019) Guides, Ne] Manzing:
Hi

I would say no.

AFAIK the provided zip files here are archives, not flashable packages.

So you would have to download the archive, extract and flash img files according to the procedure provided in the first post (using fastboot / USB debugging).

You can probably keep your current recovery if you don't flash recovery.img over it, but if I were you I would double check it will work with stock firmware. It has to be stock recovery or a compatible TWRP.

Hi,

I have been trying to figure out this problem for quite some time, perhaps someone here could point me in the right direction....

Since Nvidia messed up shield remote 2015 with bad firmware v1.38 (codename Jarvis, P2575) I'm looking for a solution to do a rollback to v1.36. Since the firmware itself is unavailable, I've been going through the source code @jenneh provided and not finding anything relevant. Subsequently I browsed and searched for the string 'jarvis' in the system.img itself from 9.0.0 for Shield 2015. I had a hit on a couple of .apks, but after decompiling I did not discover the firmware (.bin). The firmware upgrade bins for the bluetooth shield accessory in my unqualified opinion probably hide in some .apk.

I'd be very interested if someone knowledgeable would know which direction to go
