How do you update a Project Treble GSI image ?

Hi friends, so there's a lot about installing gsi images on various phones that support project treble but i cannot find anything about how you update them. I installed OmniRom beta3, via fastboot, on my H9L and 3 days later they put out an update. The rom works fine and i set it up to my preference with magisk and it even shows up as Play certified, so all is good. However, with the update I prefer not to go through the whole magisk uninstall/install again. Anyone here knows how you would update an existing gsi images ? If I use fastboot to load the new update wouldn't that erase everything again, as stated on the openkirin.net installation instructions ? or could i jsut fastboot the new beta3.1 over beta3 and just not do a factory reset as recommended ?
Weird everyone writes about installation and no one things about updates ?
thanks.

Good question mate. Since you're on omni I rom do you think it's better than ressuruction remix?

for me, yes, because one of the most important feature i need is safetynet to pass. Omni was easier to get it to pass safetynet checks (via magisk) then RR. I also like the way Omni implemented the dark theme, obviously all of these are just preferences both roms are good daily drivers.
UPDATE: so i fastbooted the updated img file with stock recovery and did not do any wipes. All was fine including root and certification.

ok i'll try this one, i also see this as a solution about the issue but i don't want my apps to be wipe and install again via backup because it's hassle, that's why i'm trying to get an answer on it without getting a data loss from my current applications installed.
anyways thanks bro for answering my concern. :good:

OK, I can confirm a couple things:
1. With this boot.img I have magisk
2. With this boot.img I have TWRP
But...
I have no MAC ID, so no wifi.
After a complete reset, including formatting data, still no MAC, no wifi
Could this be a difference between the international version and the US version?

So will this do all the necessary steps to root my phone and add twrp ? Im still stock and unrooted.
If so, anything i need to do prior ?

Yes, make sure you're on first android Q beta and you have unlocked bootloader.

[ROM][10.0][Xiaomi Mi 9][UNOFFICIAL]LineageOS 17.1 CLEAN, STOCK + Signature Spoofing [2021-01-21]

** Standard Disclaimer: Unlocking your Bootloader will Void your Warranty. I take no responsibility for this or for any bricked devices. These thing should go without saying at this point, but there they are. If you are here, I assume you are familiar with LineageOS, TWRP, and moving from MIUI to AOSP-based ROMs**
I've built a clean version of LineageOS 17.1 for Mi 9 that includes Signature Spoofing, but no other modifications.
This will allow those who are interested to get full MicroG support without the need of using any sort of Patcher or Magisk/XPosed Module. YOu all may have used my previous LineageOS Clean,Stock ROM and this is just an updated build of that ROM + Signature Spoofing to make life easier for those who want MicroG.
I flashed this and followed the simple steps of installing F-Droid, adding the MicroG Repo, and Installing the necessary packages via F-Droid and confirmed MicroG Self-check passes all the tests (once you finish granting the necessary permissions for each).
I prefer this over the NanoDroid or other patching methods as a much cleaner way to use MicroG with LineageOS.
Proprietary Blobs/Device Tree are DRG-Developer's as referenced in their post: here
Kernel source is by DRG-Developer: here
Xiaomi Hardware package used is the primary LineageOS from their github here
My reason for this is that there does not seem to be an officially-supported build for our device on the LineageOS for MicroG project or a recent, unofficial build.
What Works:
Pretty much everything from what I can tell
Fingerprint Sensor it working like a champ so far.
DT2W/DT2S
NFC Seems to be working but I don't have a device to test against
Known Issues:
You tell me...
Download:
849.98 MB file on MEGA
mega.nz
Prerequisite:
Make sure you are running a current AOSP/MIUI ROM with the latest firmware flashed and TWRP Installed
Install:
From TWRP:
1) Wipe Date (standard wipe)
2) Format Date ---> 'yes'
3) push ROM zip to /sdcard/
4) Flash ROM zip
4b) - OPTIONAL - Flash Magisk Zip for Root
5) Reboot to system
If you want to to install MicroG, just follow the steps outlined here in the "Install" section to get F-Droid installed, add the MicroG Repo, and install the handful of apps needed. No need for any of the patching steps.
DRG-Developer's device trees were last updated on 2020-10-18 so expect this build to reflect that. So far everything seems to function very well.

Does it support GApps too or it's only for MicroG?
Edit:
I test it and It's working well with GApps
Thanks for your build.

Sure,
I'm using this ROM for daily use since yesterday and seems like very stable since now and battery life is good.
I missed `Internet Band-with Speed indicator` and `three finger swipe screen shot gesture` that I think these features are not available in LineageOS.

Hi,
I've just unlocked my device and flashed Mauronofrio's TWRP afer that, i've installed this rom. And everytime it seems to be bootlooping. Showing the MI logo and after that it turns off and goes back to the Mi logo again. I've tried flashing it a few times, wiping data / system ETC. At the moment I'm restoring it with flashtool to get it back working. But am I doing something wrong?

Did you wipe data AND "Format" Data? When you Format data is asks you to confirm by typing "yes" in the TWRP Recovery. Try Wiping and Formatting data, then push the ROM to the phone and Flash.

Ah that was probably it. ADB Sideload wasn't co-operating so i've flashed the rom first and after that wiped + formatted the data. Thanks! I've just restored the phone but will try this later again.

Hi, does screen off fod work?

Your rom is really simple stock rom, but there is something that I can't make it work. Waze has been my pain, the map dont load and I cant make it run. Anyway you did a good job. You discovered how can we put updates in the rom?

No, you have to double-tap to wake or hit the power button to wake the screen before you can use the fingerprint scanner.

After installing, did you Install F-Droid and enable the Magisk repositories to install the necessary Magisk Modules and Location Backends? Then in the MicroG settings ensure all the checkboxes are checked?

Thanks for making this ROM. Really appreciate it.
The only small issue I am noticing is that my finance apps (example: banking apps, stock trading apps) popup an alert saying that my device is rooted (even though it is not) and this could be a security risk. The apps do still function but its a bit annoying to see this alert every time I launch the app.
Is this because the ROM has been signed with public keys? This alert does not appear when I used the iode OS ROM for Mi 9 or when I use the official Lineage OS for MicroG ROM on my Mi 8.

I'm not sure. It could be the Signature Spoofing aspect. I don't think iode has that and I know stock LIneage does not.

Development [GSI][12] Unofficial LineageOS 19 SM-X200

Instructions:
Flash LineageOS for tab a8 sm-x200
Format data from TWRP.
And wipe all partitions, then just reboot into fastboot and flash your system image
fastboot flash system system.img
(system being lineage or google gsi or whatever)
then once i have created the folder select the .xz or .gz or .img
also a fastboot -w after flashing for additional wiping wouldn't hurt
make sure you have a unlocked bootloader and have twrp installed.

According to @Vinpinto this only affects android 13 ROMs and lineage 19 is on 12, so should be no issues. I'm going to give it a try this weekend.

Edit:
Can anyone who's had a successful flash comment on any performance improvements? I want to update assuming that changing apps, navigating ui etc. will become more responsive

WARNING! This won't work on a bootloader with version U4! Flashing won't work and so you will not be able to use this guide. Unfortunately, you can also currently not downgrade the bootloader, making it impossible to get any custom stuff (custom recovery, custom ROM, etc.) on your device...
Hello there! This is another guide from me here on XDA Developers! Today, I will show you how to install LineageOS 20 on an SM-T290 and SM-T295, and yes, it works on both! Let's get started:
Prerequisites​But first, make sure you have all of this:
An SM-T290 or SM-T295 tablet
TWRP (v3.7.0 recommended for SM-T290 and v3.5.2 for SM-T295)
Unlocked bootloader
1. Download LineageOS 20 ZIP from here (There stands it is for gtowifi, but it also works on the LTE model).
2. Choose the nightly build for the ZIP, it is very stable even though it is nightly.
3. OPTIONAL BUT I DO NOT RECOMMEND: You could also choose the recovery, but that's more like the stock recovery and I recommend you to keep TWRP as it has better features.
4. Download the ZIP that has the format 'lineage-20.0-YYYYMMDD-nightly-gtowifi-signed.zip'
- OPTIONAL: Download the recovery image for LineageOS 20 with the format 'lineage-20.0-YYYYMMDD-recovery-gtowifi.img'.
5. Download MindTheGapps from here.
6. Choose the one with the format 'MindTheGapps-13.0.0-arm64-YYYYMMDD_BBBBBB.zip'
7. Follow the links to download the ZIP file.
8. Place the LineageOS and MindTheGapps ZIP to an SD card or USB drive. If you choose to also take LineageOS recovery, you will also need to place the .IMG to an SD card or USB drive.
9. Insert the SD card or USB drive into your tablet.
10. Boot the device into TWRP.
11. Go to 'Wipe' > 'Swipe to Wipe'.
12. Then go once again to 'Wipe' > 'Format data' > 'Swipe to format'.
13. Go to install, make sure that it is not install image but as flash ZIP!
14. Use the select storage button to choose the storage where the ZIPs are saved.
15. Choose the LineageOS 20 ZIP and swipe to install.
16. Wait until it is done and now install MindTheGapps.
17. Optional step (depending on whether you have the following things):
- Install Magisk (root) ZIP if you have it. You could also do this later on.
- Install LineageOS recovery ZIP if you have chosen to use it. This can also be done later.
17. Click on 'Reboot system' or go to 'Reboot' > 'System'.
18. Wait until the boot is done.
19. Go through the setup, but WAIT! First read the step below.
20. Depending on whether you have LineageOS recovery or TWRP, you need to enable the option 'Auto-update LineageOS Recovery/LOS Recovery' in the setup if you have LineageOS/LOS Recovery and disable that if you have TWRP.
21. Once the setup completed, you are done!

That was easy to follow. Thank you.

Yes. I was previously running a GSI, but I like this better.
I'm not using Gapps, so I just skipped para. 16. I did install Magisk.
Does OTA update work with TWRP, or only with Lineage recovery?

It does work with TWRP. It uses an OpenRecoveryScript. If you have Gapps (which you don't have), you need to reflash them afterwards. Also Magisk needs to be reflashed, but it is much easier to do than the stock!

How does this tablet with LineageOS work now?
Has it become more responsive than the original Samsung ROM or does it continue to suffer from the same exasperating slowness that characterized it?

Hello, thank you for the installation guide. Used my T290 and everything was working perfectly fine... I then decided to use LineageOS for MicroG and also everything ist working...
LineageOS 20 for MicroG:
gtowifi
My other SM-T295 is now on Bootloader5 (T295XXS5CWA1) so I think there is no way anymore to get LineageOS 20 on it. I now ordered a "new" SM-T295, which is supposed to be on Android 9. When I use the Guide above, is the cellular modul and LTE working with the CustomRom? Or should I use the GSI? Why is it such a different between those two devices?

Hello there! LTE will not be included, but you have 2 workarounds:
Make a hotspot over Wi-Fi with your phone or any other SIM device
Use the GSI ROM, which may have support
Well, LTE doesn't work, because of this: LineageOS is made on base of the drivers and packages of the device. And, they are almost the same I think, that's why the other stuff will or should work. But, the SM-T295 also has a driver and/or package for the SIM, LTE and so. And because it was originally made for the SM-T290, instead of an SM-T295, it will not include those drivers and so the support for it. You could try a GSI, although I had issues with it. But I may have done it wrong or so.., I always say: if there is an official custom ROM, use that over GSI, because it was really made for the device and includes the drivers and packages for the device. Although I don't really know whether GSI is bad, it may also work correctly..., if you try GSI, and it doesn't work, you could take a look at this: https://forum.xda-developers.com/t/gsi-lte-fix.3925151/

That's I think because your bootloader version is 4 or higher, instead of 3..., this updates after an update, and it can also not be downgraded for now. Bootloader version 3 has not got this protection that disallows flashing custom things like TWRP. Bootloader version 4 and higher do have...

Hello, I ordered a "new" T295 with Android 10, but it is T295XXU4BUD3 as well, like my old T295. Is there still no way to get LineageOS on it.
I must say I am very disappointed now. I tried so many things bought 3!!! Devices.. It is just to much work to get LineageOS on a tablet. Is there any (small Tablet) that I can put LineageOS on with LTE which is working. Man, I am trying this for 2 years now..... What about Sony Tablets?

Well, an old Samsung Galaxy Tab 4 with LineageOS 18.1 (Android 11). I helped someone today to get it on his device! It was very easy to do, so.
