How to bring stock voltage parameters. Turn off OC on R1.5.1 : )

My friend

I installed R1.5.1 to escape bootloop after canary magisk flashing and it's working but I don't want any OC :crying:

How to bring it to stock values? Plz
[Shield Android TV Android Development] adroman7:
twrp-3.3.1-0-shieldtv-pie.img doesn't see USB OTG, tried any filesystems available :)

twrp-3.3.1-0-shieldtv-pie.img doesn't see USB OTG, tried any filesystems available including fat, fat32, ntfs, exfat and dozens of high end sticks like transend, kingstone, adata, apacer : )

:eek:
[Shield Android TV Android Development] automaticfts:
I have the exact same problem. I really wish I could do a TWRP backup on the newest build... but I can't until this USB OTG mounting thing gets resolved. If I re-flash to an older recovery image of Shield, then the last stable version of TWRP works fine. Like you said, though... the newest version doesn't see an USB drives.
[Shield Android TV Android Development] dk1keith:
Same thing on my 2017 Pro shield tv. Not willing to try anything with my shield if I can't successfuly backup and restore from TWRP.
[Shield Android TV Android Development] z10m:
Can we expect overclocking to be possible on 2019 shield TV in the future or is it unlikely.?
[Shield Android TV Android Development] skaif:
So I still can't get shield tools to run.

Downloaded all the apks and tried them to no avail. Just get item not found. Anyone got a fix?

This kernel is running great for me since I installed it, but just wondering if this will work with the last 8.2.0 update that just came out?
[Shield Android TV Android Development] bl4dy_pt:
It's just a incremental update so it should be working fine, I'll update later
[Shield Android TV Android Development] go2xraj:
I have flashed 1.5.1 on 8.2 in a 2017 shield tv.

It works great...
[Shield Android TV Android Development] snake218:
HI, please can you help me with a couple of things:

- I'm at 8.2 stock (unlock bootloader, 2017 16gb) can i install this? does reset settings?

- Do you lose wide wine L1 if you root/install kernel? can you still play HD and 4k on Netflix?

Thanks
[Shield Android TV Android Development] go2xraj:
When I installed, settings was not resetted, all contents was playing good in HD and 4k
[Shield Android TV Android Development] snake218:
Thanks for answering, last question. Do i need to use a stock image (currently installed) or do i need to use a developer image? thanks
[Shield Android TV Android Development] go2xraj:
I have tried both, I feel stock was better than developer image.
[Shield Android TV Android Development] snake218:
Thanks for all your help, i will flash kernel today on top stock image, thanks again.

EDIT: Finally could flash it, had problems with bootloop after flashing Twrp, so i reinstalled Stock firmware (Nvidia instructions, didn't factory reset so all was preserved) , and boot Twrp (without flashing) to install kernel.

EDIT2: I would like to know, if someone has been running full Overclock, with max performance mode and fan set to coolest (in normal settings) any issues long term?
[Shield Android TV Android Development] lenana:
I've been running mine on full OC mode for more than half a year, never tampered with fan settings just used the default figures on the kernel. No issues whatsoever (Shield pro 2017).
[Shield Android TV Android Development] go2xraj:
Don’t flash twrp just follow follow these steps

Step 1: boot in to boot loader by the command - adb reboot bootloader

Step 2 : check the fastboot by the command - fastboot devices

Step 3 : use only twrp 3.3.1.0 pie ( don’t use any other twrp) you can google search or find it in the forums

Step 4: now flash twrp 3.3.1.0 pie by the command - fastboot boot twrp 3.3.1.0 (drag the twrp file location)

Step 4: it will boot to twrp and now flash and install kernel 1.5.1

Step 5: now reboot system

Step 6: install shield tools 1.3 app and unlock all performances

Follow these steps let me know if you have any issues.

If you want twrp 3..3.1.0 pie, I can send it, let me know.

https://androidfilehost.com/?fid=1899786940962582857

I'm putting together a megaupload and guide for 8.2.0 w/ overclocked kernel and magisk...should be up tomorrow
[Shield Android TV Android Development] bum2kev:
Ive been reading about people having issues on 8.2. do you think I should just wait till they push some patches before going 8.2 on the OC?
[Shield Android TV Android Development] simonk206:
I dont have any issue
[Shield Android TV Android Development] tha kid2012:
The only issue I had so far after overclocking (everything maxed out, governor set to Performance

and the fan left alone) is when I use the Dolphin emulator, after about 5 minutes the game freezes. I can still hear audio and can still control the game but nothing else. I have to restart the whole Shield because the freeze somehow causes my tv screen to go black every time I try to open any app, I have to guess where the restart button is everytime. Luckily I know how to get to it blindly with no problems but that's been my only issue so far with overclocking. I notice a nice improvement otherwise in Retroarch emulation. The Sega Saturn (Yaba Sanshiro) and SNES (bsnes) core is faster, mainly bsnes when you try to emulate super game boy games, they went from stuttering to 100 percent full speed.
[Shield Android TV Android Development] berpru007:
Dolphin performance are better ? Have you tried not to max out everything ? Dolphin is hard to run on the shield tv... Have you tried mmjr ?
[Shield Android TV Android Development] GollyJer:
Hey [MENTION=4180946]rootfan[/MENTION]. I'm curious if KLapse is something you would consider building into the kernel?

It basically adds "Night Mode" at the kernel level which would be AWESOME for nighttime viewing.

KLapse-LiveDisplay on GitHub

The maker of Kirisakura kernel integrated it pretty quickly when I asked about it for the Pixel 3XL.

Thought it couldn't hurt to ask here. ?

How cool would it be to have your TV and phone dimming with the sunset?
[Shield Android TV Android Development] meksis:
Can anyone say that further development has stopped?
[Shield Android TV Android Development] mrhamed:

[Shield Android TV Android Development] Yooshaw:

Perfect, thanks so much!
[Shield Android TV Android Development] Zacharybinx34:
Curious, how does it run?
[Shield Android TV Android Development] Zacharybinx34:
does this work on 8.2.1? I installed it, but it doesn’t give me any options to change the frequencies higher. Can’t change fan either, and it says “either root is disabled or you are running the wrong kernel.” But root is enabled.

Thanks!!
[Shield Android TV Android Development] kyvaith:
Could anyone please tell me the steps to compile a kernel and build zip for flashing like the one you attached? I would like to add DVB support to it. Thanks.
[Shield Android TV Android Development] Zacharybinx34:
Flashed this, and my Shield just sits at the NVidia logo.

What order is this supposed to be flashed it?

This post REALLY could use some better instructions.
[Shield Android TV Android Development] user_19:
Thank you so much for this! The performance increase is amazing on Shield 2015.

For questions regarding Compatibility: Check that the first five digits of your kernel version under System-> Info match with the one you are about to flash (4.9.140-xxxxxxxxx), that should work, I am on Shied TV 8.2.2 .

Widevine (Netflix etc.) is not affected.

Flashing instructions:

1. Boot to fastboot ( adb reboot bootloader )

2. Unlock bootloader - this will wipe ALL of your data ( fastboot oem unlock )

3. Reboot and reenable developer options

4. Boot to twrp ( fastboot boot your/twrp/image.img

5. Via MTP place the Kernel in the shields /sdcard

6. With mouse flash the kernel using the gui

7. Boot the device

8. Install Shieldtools.apk ( adb install path/to/your/shield-tools.apk

9. Launch Shield tools and grant root permissions permanently

10. Tweak your settings

11. Enjoy your overclocked Shield!

I have maxed out all settings and it is working great, additionally I changed the fan settings for >70°C to max speed, since then I don't get any freezes.

I have tested one game of which I knew performs badly on stock shield settings (Mario Kart WII on luigi circuit) and Dolphin MMJR, on stock Kernel. With all performance enhancing tweaks the max game speed on the first map is 78%, native Wii resolution.

Using the same conditions with maxed out kernel and performance governor the max game speed goes as high as 92% - when there is not too much action going on on screen! It is definitly playable now though.

On 720p Fps vary around 44 and 47 and the game speed is between 70% and 80%, looks nice, but feels slow.

Sling Shot Extreme Open GL ES 3.1 on 3DMark gives 4438 points and Sling Shot on 3DMark gives 512 points, making it better than 95% than all other shields according to the stats.

Thank you very much for this development.
[Shield Android TV Android Development] ruthless10001:
Hi everyone i cant seem to find the latest shield tools apk can anyone provide a link? Thanks in advance
[Shield Android TV Android Development] ruthless10001:
Again, thank you for this @go2xraj
[Shield Android TV Android Development] @muja@:
@rootfan,thanks for great works of your mate, cheers and respect.Keep it up!!!
[Shield Android TV Android Development] brynhh:
Hey there. I've installed things and run other tools on my Pixel before so know how adb works, but could you explain where each of these steps take place please? The nvidia website says fastboot is possible just via a button on the shield 2015, so it would be good to have the exact detail to minimise any risk, rather than discovering as we go along.

Assume this is on PC with USB-A to USB-A into shield.

As with 1

Are developer options on the Shield menu system? Does it need 5 clicks somewhere like on phones?

As with 1

What is MTP and does this mean copy files from PC to shield?

Is this mouse action on PC or Shield?

Remove power and reinsert power I assume?

As with 1

On PC or Shield? How is the grant given?

As with 9.

Thanks very much for any help you can give.
[Shield Android TV Android Development] Dcxtreme84:
Ignore my ignorance, but I have a 2019 Pro, is there a reason that the same overclock work isn’t being done on that model?

Would love the increase in performance for Emulation, doesn’t the 2019 pro still use the same CPU?
[Shield Android TV Android Development] hedgegee:
Anyone know what to do with a TWRP error 1 when flashing the kernel zip? Says system cant be mounted (i tried to adb mount and works fine) I have tried some earlier zips and same thing. I have unlocked the bootloader.

I am on 8.2.2 (newest as of writing) with my TV Shield 2015?

Thanks for the work :)

EDIT: Forgot some text
[Shield Android TV Android Development] tha kid2012:
So let me get this straight as far as the fan settings, the default numbers for Temperature C are 0, 45, 56, 64 and finally 70. You're saying you maxed out each of those numbers and left the following numbers after 70 default? Because I maxed out all those numbers up to 70 and Dolphin still freezes on me after a couple minutes and I have to power off the Shield completely. This is the only nitpick I've been having with overclocking since I installed this kernel. Can you post a screenshot so I can mimic your setup?
[Shield Android TV Android Development] hedgegee:
No one? :(
[Shield Android TV Android Development] Neuken6969:
Seems most if not all shield tv threads are dead.

I'll ask any I'm 8.2.3 can I root and or rom?
[Shield Android TV Android Development] George@xda:
Hi,

I did it on my Shield TV 2017 16Gb with dev OS 8.2.3 and Kernel_R1.5.1._Beta.zip. It`s rooted, overclocked and working fine.
[Shield Android TV Android Development] Ghisy:
Would you mind sharing the process please?
[Shield Android TV Android Development] George@xda:
Sure, I flashed developer OS 8.2.3 according to NVIDIA instructions first. Then I booted into the TWRP and flashed the Kernel_R1.5.1_Beta.zip, according to the information from above.
[Shield Android TV Android Development] toddre:
Ghisy, how did that work out for you? Were you able to install the .zip file in TWRP and achieve root with Magisk?
[Shield Android TV Android Development] Ghisy:
Nope, it doesn't work: I'm getting an error, TWRP cannot mount /system. :( (I used and booted into the latest TWRP 3.5.2._9-0-foster.img)

Ugh, now my Shield TV doesn't boot anymore. It's stuck on Nvidia's logo!! Yeah, it's bootlooping... Great.

Edit: I had to plug in a keyboard to boot into fastboot and reflash the dev image. Now it boots again.

That Kernel_R1.5.1_Beta zip file doesn't work for me to root. Be aware!
[Shield Android TV Android Development] go2xraj:
Find twrp pie image and install it, and then flash 1.5.1 it will work
[Shield Android TV Android Development] rootfan:
I don't think so. Twrp recoveries built for SE 7.2.3 do not boot with the newer bootloader. Also, twrp doesn't work with otas, so you'd have to install the stock recovery anyways.
[Shield Android TV Android Development] imoldchen:
[MENTION=4180946]rootfan[/MENTION] Use the PIE / SHIELD EXPERIENCE 8.0 ROOT METHOD on my 2017 model, It's not work, Twrp to flash magisk_shieldtv_pie.zip, and reboot into bootloader, Unable to enter the system.
[Shield Android TV Android Development] skyline78de:
Hello,

so when I'm on 7.2.3 I have to flash boot_r12.img with fastboot and after that I have to flash ShieldOC_Magisk_Test.zip with twrp?
[Shield Android TV Android Development] oldpoem:
I just flashed kernel with magisk on SE8.0/Pie on my shield 2015 (16gb). Works fine , everything feels snappy, Root works! Magisk modules works!

What surprised me is my chinese p2p iptv which crashed after updated to oreo now works. Very happy indeed.

Thank you for this kernel / magisk / root for pie.

[Shield Android TV Android Development] elliwigy:
cant we pull the vbmeta (if it has one) now that we have root then fastboot flash it and set --disable-verification and --disable-verity??

actually nvm lol.. might not work anymore.. i tried fastboot flashing a patched vbmeta and i got an error.. either way, i prefer to use ur kernel anyways :)

r u tryna do it dirty? i get similar issues if i try to do everything without wiping or starting from fresh stock
[Shield Android TV Android Development] whiteak:
Think you are meant to direct this at someone else? I have no issues, I also always start fresh as well, so that could be the other person's issue.
[Shield Android TV Android Development] elliwigy:
yea, meant to tag the other person who had issues..

im satisfied tho.. everything is working flawlessly here
[Shield Android TV Android Development] BXM500:
Has anyone managed to get it work on 8.2.3?

When I flash the latest 1.5.1 kernel I don't get the root. Meaning the rootfan 1.3 app won't apply the overclock settings.

When I flash the latest Magisk 23 to get the root - I will lose the 1.5.1 kernel.

Catch 22?
[Shield Android TV Android Development] vincentanzalone:
I was having a hard time with getting magisk to work on mine, so once I did I wrote up a little tutorial to root on 8.2.3. Basically download boot-magisk23.0.img then flash in fastboot.

fastboot flash boot boot-magisk23.0.img

Root tutorial for 2017 Nvidia Shield 8.2.3
[Shield Android TV Android Development] toddre:
Interesting, I had no luck getting root on 8.2.3. The boot image you posted was created with Magisk? Have not tried your image but the best I was ever able to get was a loop. Will post a follow up after investigation.
[Shield Android TV Android Development] vincentanzalone:
Yes, the boot.img that I patched with Magisk was pulled from the Nvidia developer firmware, so it should work on 2017 version Shield running on 8.2.3
[Shield Android TV Android Development] toddre:
Anyone else having any LUCK?? Still no luck for me. I have been rooting two of these 2017 Shield's for years and have never had a problem in the past. I will have a go with my second unit since I only used my primary unit as a test bed rooting 8.2.3, didn't see any reason to try on the second. Not really a big deal since having root is not very important to me anymore as in the past.
[Shield Android TV Android Development] Don_Pachuco:
So I only read the first page on this, but does this, or any rom for the shield P2571, work as a one click type thing, or what do you have to do to flash a shield? Also, anything newer in terms of Android version or what have you?
[Shield Android TV Android Development] beatLeo:
So, is it possible to use the kernel on 8.2.3 on nstp 2015? Please, i would like your answers.
[Shield Android TV Android Development] Adromir:
It probably should work since kernel Version didnt change as far as I can see
[Shield Android TV Android Development] beatLeo:
Ok, i'll do it. I've been waiting so long to root and improve my shield. I have a 2015 pro. But i need a recovery image for 8.2.3, just in case i breake my shield. Does anybody knows where can i find a recovery image?
[Shield Android TV Android Development] Adromir:
https://developer.nvidia.com/gameworksdownload
[Shield Android TV Android Development] beatLeo:
By the way, is this ok? My benchmarks are way below the one some people have put here. And i always tought my shiled tv pro 2015 was a litle bit better because it has a 500 gb ssd M.2. And by the way, how can i choose vulkan on 3DMark? i don't find the option to choose.
[Shield Android TV Android Development] xd4d3v:
It's anyone maintaining this? I'd love for the kernel to include the USB tv tuners. That was abandoned a long time ago as far as I know
[Shield Android TV Android Development] beatLeo:
And now with android 11 rolling, is someone going to make this kennel for this version?
[Shield Android TV Android Development] Zacharybinx34:

[Shield Android TV Android Development] rchris494:
rootfan hasn't been seen since feb 2020. it would be nice if someone would pickup this project and update to something current. i have spent too many hours trying to get root on my shield with 8.2.3. i am beginning to think it just isn't worth it to remove the bloatware. i can get root flashing Kernel_R1.5.1_Beta.zip. the minute i use system app remover to remove 1 app. reboot and then it goes to nvidia logo and back to recovery. it will not boot to the os. so i have to wipe everything and start again. it's sad we only have 1 choice for rooting and even that doesn't work
[Shield Android TV Android Development] rchris494:
@rootfan thanks for the kernel update. keep up the good work!
[Shield Android TV Android Development] go2xraj:
@rootfan it works flawlessly on 9.0.2 too,

Thanks for the kernel
[Shield Android TV Android Development] lenana:
Thanks @rootfan for the update!
[Shield Android TV Android Development] andyx1985:
With the newest magisk not having magisk hide will I lose functionality by rooting the shield 2015? Like Hulu, Disney, Netflix etc? Or if they work will the quality be downgraded because of root?
[Shield Android TV Android Development] beatLeo:
Ohhhh this is actually really good news. Good to know @rootfan is ok, and keep working for this dear shield. I'm still on android 9, but as soon as nvidia gets everthing to work ok i will be on android 11. But, for now, i would like to ask some questions:

- I'm on android 9 with root and kernel 1.5.1. I believe i shouldn't update to 11, because i will loose the root. But, being on android 9 with root it supposed to be more easy to enter the recovery and make a clean flash of androd 11 and install the magisk and kernel, right? Sorry if this is a dumb question, it's just that after i made the shield root, i forget everthing about how to make it root.
[Shield Android TV Android Development] go2xraj:
@rootfan on 2017 it goes to boot loop on 1.7 but 1.6 works
[Shield Android TV Android Development] rootfan:
@go2xraj , would you see if the attached kernel works? If it does, it would help if you could post a log by doing the following:
