How do I update rooted shield tablet to marshmallow?

OK, so I have a shield tablet that is running a rooted stock android version 5.1.1 and I want to update it too marshmallow and retain root. I have TWRP as my recovery. What's the easiest way to update? I found a thread for updating to marshmallow and it said it had the auto update file removed (which is good) but the downloadable files were removed from the thread by the OP... I should mention that this tablet is the newer recall replacement tablet that I'm trying to update, and that I still have the old recalled tablet with the auto update file removed so it never got killed. I'm not updating the old one though, just the new one.

You have to take care, not to overwrite the recovery partition. At least for the K1 there is an MM stock ROM on the official website. The version for linux simply contains partition images and a script, which fastboot flashes those. Commenting out the line which flashes the recovery would do the trick.
I'm not sure though if there is a similar ROM for the original.
Ah... no, with a locked bootloader it's slightly more complicated, since a 5.x twrp won't start on with a 6.0 staging blob.
Ok. Assume you've got the partition images. You have to (fastboot) flash everything but the blob and recovery first. Then boot into TWRP (the rom does not boot now) and flash your favorite SU tool. Then fastboot flash the blob. Now the rom should boot and give you root access. Finally update Twrp to 3.x.

Oh OK, thanks. I think I'll just wait. I'd rather flash a community stock/rooted rom. I don't want to flash an official ROM and have to re-root and flash recovery and all that... That's all just too much work right now just for marshmallow lol. My 5.1.1 is working fantastic so I'll just leave it for now. I'm curious why its so complicated now though with MM? I don't ever remember any previous build jumps requiring so much work to update to... My nexus 5 wasn't difficult at all. I just downloaded the full rom zip (MM Cataclysm cause I was on Lollipop Cataclysm), booted into TWRP, dirty flashed the zip, and it was good to go. I'm looking for THAT kind of update for my shield tablet.

If you unlock your bootloader (which is recomended for using custom roms), then getting root is simple, since you can fastboot flash any partition image.
Independend of your currently installed rom you can always get root by
1. (fastboot) flash the correct (2.7.x for Android 5.x, 3.x for Android 6.x) TWRP recovery
2. boot into TWRP an install a current SuperSU zip.
On the shield tablet you need to flash a new staging blob for MM in any case.

I am attempting to update to marshmallow as well so i can install kali nethunter 3. but i am unfamiliar with rooting i havent done it since 2010. where would i acquire these files that i need to flash to the shield?

Can/Should I install update?

I have my Pixel (obtained from Google) rooted. I have not installed any Kernels or Roms.
I received a notification that there is an Android system update. Is is OK to install this update?

Based on your comments, I assume you are not on Verizon - if that is the case, whether you do an update or not is completely up to you - I have the GOOGLE PIXEL - am using ATT service and I am also rooted - I updated - ultimately I had to re-root - install Twrp and flash the rom I wanted to use - but beyond that - no reason not to - completely up to you. Good luck.

So, if I install the update, I will lose TWRP and root?

You never want to take an OTA update if you have a custom recovery. Can and will brick your phone. As long as you have stock recovery your more than welcome to take an OTA update.

Restored factory boot.img to boot_a and boot_b
When I try to install the update, it says "Installation Problem"

[TESTING] Flash Patched boot.img to achieve Systemless Root

WARNING:
Please do every preparation that could fix your phone to original state before doing this trick.
DOING THIS MAY VOID YOUR WARRANTY, DO IT AT YOUR OWN RISK
I managed to unpack the official firmware of Nokia 7 and 8, and patched their boot.img with SuperSU Systemless Root.
But I don't know if it works on them.
Patched boot.img can be downloaded at:
https://mega.nz/#F!igsBmarT!3rIjD4ZaZN8ueOTVmciGwg
Here's the method you need to do:
1. Install OST LA and patch it, and OPEN IT FROM INSTALLATION DIRECTORY DIRECTLY.
2. Flash required firmware before proceed. If you don't do that, you won't be able to access Wi-Fi after the boot.img flashed.
For Nokia 7, you need to use the firmware "C1N-0430-0-00CN-B05" which I haven't released to public for some reason.
For Nokia 8, you need to use the firmware "NB1-435J-0-00WW-B01" which released in this topic: https://forum.xda-developers.com/showthread.php?t=3678487
If you've already flashed required firmware before proceed, you can skip this part.

3. Use the Service Purposed Bootloader trick I've mentioned in the Nokia 6 Root Guide: https://forum.xda-developers.com/showthread.php?t=3702354
4. Type these commands:
Code:
fastboot-android flash boot_a E:\NB1-435J-Boot-Patched.img
fastboot-android flash boot_b E:\NB1-435J-Boot-Patched.img
fastboot-android reboot
For Nokia 7, use C1N-0430-Boot-Patched.img instead. I've attached the Firehose, rawprogram0 and patch0 for Nokia 7 in case you want to use EDL Mode on Nokia 7.

5. If it's accepted by the system, the phone will reboot twice, and you'll see SuperSU appeared.
However, if "Verification Failed" appeared on your phone, then the trick failed. You have to flash original firmware to restore your phone to factory state.
If anyone know how to fix that in boot.img, that's a breakthrough of Nokia Android Devices.
You may want to use Flashfire to flash Xposed Framework or something else, but DO NOT RECEIVE ANY OTA UPDATES after your phone rooted.
I'm looking forward to a boot.img manual patcher on PC or Phone available, which could patch boot.img to achieve Systemless Root either SuperSU or Magisk and bypass Verification Boot.

This looks exciting. I have to look deeper into recovery options before I dare this kind of experiment...

Tried on a retail Nokia 8 TA-1052 running 00WW_4_35J_SP01
Boot passed but unfortunately no root
End up having to upgrade to 4390 using 4G
Update: Can't install 4390 even when I download the update multiple times. Flashed 435J using OST and tried flashing the kernel again but still no root.

Thanks for feedback.
I'll check if anything wrong.
Can you check if you can install SuperSU manually from Google Play?
After you installed it, is root available?

Nope. SuperSU said "Root not available"

Many thanks for your efforts on this patch, I would love to be able to root my Nokia 8.
Having an unlocked bootloader I am not really worried about, but having root access is a big feature for me.
Any chance this patch will become available to firmware version 00WW_4_390 which is the current latest? (And what my phone is currently running)
Not sure if I can downgrade it to NB1-435J-0-00WW-B01 or not, but I can try that if it is not able to be patched to the latest firmware image.

Thnx hikari_calyx for your hard work!

Hey we need developers here on Nokia!
And what we need to is a dev who build twrp for Nokia8. The recovery is inside the boot. IMG.
If you want build a one for the community. Thanks

[GUIDE] How to root your Nokia 8, and keep the ability to do official OTA updates

So as the official bootloader unlock broadened the audience of this from tinkerers/developers to basically everyone I thought this guide might me helpful for some...
PREREQUISITES:
- Unlocked bootloader (official or unofficial)
- latest magisk manager installed on phone (https://github.com/topjohnwu/Magisk/releases)
- latest fastboot and adb binaries from google(https://developer.android.com/studio/releases/platform-tools)
- latest twrp.img to boot (NOT FLASH), zip not needed (https://eu.dl.twrp.me/NB1/)
- Fully stock partitions (if you do not have this reflash latest stock via ostla), as OTA updates will do a integrity check.
- PC with WIN/OSX/LINUX with USB port^^ (on windows you might have to add .exe to the commands)
- disable automatic system updates in developer options, as you will still have to manually root the updated partition, so this makes sure you don't miss it. You still get notifications on available updates and can apply them easily(as you will see)
SETUP_STEPS:
1. Go into Magisk manager and "just download" the latest zip
2.1 Run
Code:
adb reboot bootloader
or reboot into download/fastboot mode via other means
2.2 Run
Code:
fastboot boot twrp-3.2.3-1-NB1.img
(change this when your version of twrp differs)
2.3 Flash the .zip magisk downloaded in 1.)
2.4 Reboot.
Congratulations you now have root!
STEPS_TO_UPDATE:
1. Go into Magisk Manager -> Uninstall -> Restore Images
2. Apply Update, DO NOT REBOOT YET
3. When step to finished and it promts you to reboot go into Magisk Manager -> Install -> Install to inactive Slot
Congratulations you can now reboot and will have an updated Android while keeping full root.

ALTERNATIVE GUIDE (without twrp, using prerooted boot.img)
(works for newest patch level, where twrp isn't working yet)
this guide works on newest patches as long as someone provides a prerooted boot.img.
So basically you either need a boot.img available or twrp...
Hopefully this helps until TWRP is compatible with September Security Patch
LINKS:
stock boot.img: (may to october patches)
https://cloud.vault81.de/s/fnoizKwi8kNF3Rg
prerooted boot.img: (may to october patches)
https://cloud.vault81.de/s/AeHiE5HR2qonb3N
PREREQUISITES:
- same as above minus twrp
- patched/prerooted boot image (either create it yourself or use link provided here)
STEPS_TO_ROOT:
0.
Code:
adb reboot bootloader
or get into download mode otherwise
1.
Code:
fastboot boot NB1_prerooted_boot.img
1.1. The phone will boot into an temporarily rooted state,
2. Use magisk manager-> Install -> "Direct Install" to persist the root.
3. Reboot
Congrats you now have root even on versions where twrp isn't working yet....
Edit1:
Added link to all stock boot images from may to october security
Edit2:
Did the same for magisk prerooted
Edit3:
Added November images thanks to @czupyt

TWRP isnt working right now so whoever updated to September patch cant do anything except unlock bootloader. Unless someone can pull a boot.img from the newest patch so we can all patch it through Magisk and get root.

I have working magisk on september patch so I should have both prerooted and Stock (cause Magisk backups those)

That would be much appreciated. Alot of people who just unlocked bootloader cant root and the maintainer of our TWRP will take a couple of days

Simple Solution: A/B Partition System.
One Slot is the September Update, the other is August Update.
Update to September, Unlock, witch to other Slot with August Update, Boot Offical TWRP 3.2.3-0 (-1 not booting tho).
Now you can Install the Install Zip for the August BL and Magisk.
Bootup and use Magisk for Inactive Slot.
So did I, but I'm still on August Slot, I'll try to root the September Boot Partiton, and Install TWRP later when Fix arrived.
But rooted September doens't seem very... Stable

I'm already about to install the September patch again. I downgraded to May so I could root my phone and provide the clean boot.img from the stock September so people can root without twrp. And honestly A/B partition is still new to me that I still don't understand it

A/B system is not Complex at all. It's just having 2x a Partiton Group (Boot, System, OEM and Recovery I think) and having the ability with Fatboot to simply switch between group A and group B.
You Inital Set up Partiton A (Nokia did for us with Nougat 7.1.1). If you Update, the Update will be extracted to Partition B, aftzer finishing you reboot to Partiton Group B, leaving group A untouched in Case of Error on Partition B.
That's it pretty much.

No I get that but its just that I forget cuz this is my first phone with a/b partition. Anyway I got the phone to latest patch rooted so I'll see if I can get the untouched img

On what step? Was it after you completed the guide? Or did the patched image not boot already?
If the patched image worked but it din't afterwards, you should reflash the stock_boot.img and redo the guide again because you probably flashed twrp and broke your bootloader...
As you can see in the prerequisites this guide requires a stock bootloader to start.

So did the prerooted Image Boot?
If so it basically has to be your boot/system partition(I had mine compromised too and couldn't fix it with just flashing boot.img had to reflash everything via ostla)
If even the prerooted Image didnt boot im sorry i don't really know how to help, as I have working root with Magisk on September patch and the Image boots just fine for me....

Also you could Switch slots to revert back to august Patch and use the normal twrp guide then... And run the September Update via the magisk method

Hey everyone;
My Nokia TA-1004 is on the July SP (4.88B_SP02) with unlocked bootloader (unofficial method), TWRP and Magisk installed.
Where can I find a stock boot.img to flash? I tried flashing the boot.img on this thread and although I can boot fine my wifi will be broken (I tried and had to restore nandroid backup). I also tried following the guide here but my OSTLA won't get past "Flashing Service Bootloader".
Any help?

Flash the full Stock build (i think its even may patch), via ostla (https://forum.xda-developers.com/no...ia-8-official-firmware-links-updated-t3678487), then follow this guide then reapply all updates by following the update steps...

So which file do I have to download from https://drive.google.com/drive/folders/1t64iHuQQjmMnzcujZtjYplh6ipbiF6Cw ? I tried with the 488B one and got stuck on "flashing service bootloader"...

Install twrp on android 11 rooted

I just rooted my samsung s10 G973F / DS via Magisk (not without some bootloop issue and a couple of times I had to flash the stock firmware and then the patched one).
I would try to include havoc custom rom which has great reviews for wanting twrp first.
So that the March 2021 update for Android 11 support is out, but I need a guide, in fact I wonder if I flash the twrp 3.5.2. from odin, do i need to reinstall magisk from recovery twrp or is my root safe?
Thanks to who will answer me!

Have the exact same question in mind. Hopefully someone will respond soon
