Upgrade stock samsung firmware on rooted device - Galaxy Tab S2 Q&A, Help & Troubleshooting

I'm running stock android 6.0.1 T710XXU2CPD9 on my T710. I'm rooted with latest SuperSU, removed some of the pre-installed system apps and installed TWRP.
I'm still on the security patch of april and want to upgrade to the latest security patch.
I know that I can download stock firmware from sammobile but my questions are:
1. How do I install it ?
2. Do I lose SuperSU / TWRP when I do ?
3. Is there a way to build flashable zips / debloat the firmware before installing?

You install the new firmware with Odin, then reflash TWRP, then SuperSU and encryption disabler. That's the most straightforward way I believe, unless you know how to extract the bits from the firmware and make a zip.... but that seems like just as much work or more, to me anyway.

Rooted + TWRP stock ROM update question

Hi I have a xt1803 G5S Plus, retgb and have recently unlocked bootloader and rooted my stock ROM which is NPSS26.116-26-14.
I have noticed there are higher version numbers available like NPS26.116-61. How do I go about having the latest stock ROM with twrp and root access? I'm guessing the stock ROMs are not flashable via twrp. Would I have to flash the latest stock ROM via ADB like it explained here
https://forum.xda-developers.com/mo...lash-official-firmware-moto-g5s-plus-t3681018
and then unlock bootloader again, flash twrp etc like starting from scratch?
I honestly would not recommend flashing NPS26.116-61 to your device. Despite the version number being higher, that firmware is actually for a different region (I think NPS26.116-61 series firmwares are for India and Indonesia, whereas the NPS26.116-26 series is for EU/UK). If you flash that, you may find yourself ineligible for OTA updates at all, since your build does not match that expected by the stock OTA servers, and if there are incompatibilities between the firmwares - since they are for different regions - you may have issues with IMEI/SIM access.
If you wanted to update though, you'd have to follow the steps in that guide. Though I don't have a G5S Plus, you would have to remove TWRP/root through a stock ROM flash (no need to re-lock bootloader), then update via OTA, then flash TWRP and re-root. If you can find a stock ROM with the same firmware build as you have now, you may be able to preserve your data by omitting the 'fastboot erase userdata' command from the stock ROM flash commands, but I would recommend you have a backup (e.g. TWRP backup) before flashing anything.
There's a copy of the NPSS26.116-26-18 stock ROM (June 2018 stock ROM) here, flash at your own risk: https://forum.xda-developers.com/showpost.php?p=77025728&postcount=507 This build was released as an OTA update to retgb devices as reported here: https://www.reddit.com/r/MotoG/comments/8w0c0c/june_patch_now_available_on_retgb/

Software update and root

My phone is rooted and I have a custom recovery installed, but I'm on stock firmware. When I search for software updates, it doesn't tell me my device has been modified, but just goes on to say I'm on the latest update (August security patch for my region).
My question is: when the September security patch arrives, will I be able to do the update without losing root or any other issues?
If your on the snapdragon note 8 u cant root and never will be able to again

Hi mate,
As long as I know:
- you wont be able to use OTA sine you did root. (strange the is not saying your device has been midified. just install root ckecker from goole play to make sure you are root)
- if you flash any originial rom via Odin, your custom kernel will be replaced with Samsung original kernel and you need to root your device again.
I hope it helps you
An update, if anyone happened to be interested. The September update for my carrier is now available. When I went to check for software update in the settings, the device finally told me the system has be modified in unauthorised ways so I can't download the update via OTA. That means I'll have to download it from Sammobile and flash via Odin and lose everything and start fresh.

Sprint Z3 Play 9.0 OTA update sent to phone 7/7/19

Hi, I have the Sprint variant Z3 Play currently rooted on 8.1 with the last update from January and I received the notification that the 9.0 update is available to download and install. I've been reading on how I can install this update but from what I understand, I have to update/re-install magisk using the patched boot IMG from the stock 9.0 IMG. The OTA is labeled PCW29.85-36 however all the stock firmwares I've been able to locate are labeled PPW29.xx. Can I extract the boot IMG from this firmware to patch or does it have to be the exact PCW firmware. And is there an alternative such as unrooting the device, reflashing the latest Current Sprint 8.1 Oreo firmware, taking it back to stock while keeping the bootloader unlocked, and then taking the OTA and re-root? My only reason for the root was to run Viper4Android and would like to keep this setup. I've also read on methods using LMSA but instructions on a rooted device are a little vague to me. Any assistance would be greatly appreciated.

Question Decrypted stock firmware - Global

Hello, dear fellow 8i-Users!
I got this device just a few days ago. It is running on A32 global firmware and wasn't offered an OTA update.
So far, I have unlocked, rooted and installed TWRP, following the guide provided here.
As I like my phones to be encrypted, I guess I will stay with stock firmware so far. I'm finding it a bit sad though that I wasn't offered an OTA update and therefore am stuck with security patches dated back to November 2021.
Therefore my question: Does anyone happen to have decrypted versions of a newer version of global firmware? And if so: Is it possible to dirty flash these in TWRP?
Thank you!
Cheers,
VV

I doubt it will be possible to flash full ROM through TWRP unless you prepare extra files (like scripts which do the actual work).
Anyway you can decrypt the official firmware (the ones in OFP-format) by youself and flash it with SPFlashTool.
Here are few hints for you:
Download the version you like from here.
Decrypt it with oppo_decrypt
Merge super.img for the region you need (refer to super_map.csv to find out which parts need to be merged; refer to this comment for instructions)
Flash with SPFlashTool in Download Only mode (refer to this guide)
