TB-X505F Which Treble GSI to choose? - Thinkpad Tablet General

TB-X505F Which Treble GSI to choose? - Thinkpad Tablet General

Hi there,
i'm thinking about to flash a GSI on my x505f. Which image of a GSI do i have to choose?
The "Treble Check" app says the tablet has a-only partion, but "Treble Info" app claims the partionscheme is a/b. "Treble Support Check" app says a-only too.
"getprop ro.build.ab_update" and "getprop ro.boot.slot_suffix" returns nothing, so i guess it is a-only?
Addition question: is it necessary to use twrp to flash the gsi, or can i simply "fastboot flash system <myimage>"?

Just for the record, i managed to boot some Android 10 and 11 GSIs.
Here are the steps:
- Assuming that the bootloader is already unlocked
- Download and uncompress an arm64 a/b gsi. I successfully booted phh-aosp (10 and 11) and lir-lineage (11). Copy it to the tablet.
- Download this zip: https://forum.xda-developers.com/t/...ncrypt-disk-quota-disabler-11-2-2020.3817389/
- Rename that zip to "Disable_Dm-Verity_enfec.zip" (this is the most important step!)
- Install TWRP and Magisk from https://forum.xda-developers.com/t/...ial-twrp-3-5-x-for-lenovo-tab-m10-hd.4211221/
- Boot to TWRP
- Flash the gsi as system image
- Flash Disable_Dm-Verity_enfec.zip
- Format data (not the simple wipe!)
- After that the tablet should boot up fine
However, when the tablet is up and running there will be no navbar...
For Lineage you can do this: https://forum.xda-developers.com/t/unofficial-lineageos-r-mod-lir.4237683/post-84670345 (thx to @Heeni)
For AOSP you can go to settings and enable gesture controls, however only swiping from the bottom will work. Swiping from left/right does nothing which means you can't go back. The above workaround doesn't work on aosp. Maybe i figure this out in future.
Switching between GSIs:
- Reboot to TWRP
- Flash new GSI (no need to flash Disable_Dm-Verity_enfec.zip again)
- Format data again

FWIW, I am on 8.1 from 8.0 Nov patch and did not factory reset, just flash-all with -w removed (actually I run each command in that file myself). Everything works fine and no data/app loss...

Yeah that's what I thought. I think he just writes it just as a precaution, in case anything goes wrong on 8.1, first factory reset and then write the problem if it still persist

Supersu or Magisk
Which rooting method is best for the Pixel XL. Supersu or Magisk

Update worked like a charm on my standard Pixel.
But somehow TWRP will not decrypt, keep asking for password even though I always had a pattern which worked flawlessly in TWRP. Any suggestions so I can get rooted again?
EDIT: After a few password attempts, removing the password altogether worked. When installing TWRP.zip the command window says E:This TWRP does not have synthetic password decrypt support, that must be why I had problems.
EDIT2: SuperSU does not seem to work

Supersu wasn't even in my app drawer after flashing the zip so after rebooting I just went into the zip and installed the apk manually

Thank you for this thread....it worked. I did #9

Can confirm #10 works like a charm. Thanks for the separate thread. Both your guide threads should be stickies.

Just use adb sideload...
If you want to keep all your data, just sideload the OTA via adb, instead of flashing the full factory image...
My Steps:
1) Flash stock boot.img (November for me, I used TWRP)
2) Reboot recovery
3) Choose: Apply Update from ADB
4) adb sideload marlin-ota-opm1.171019.011-9e7f2bb8.zip
5) reboot system
6) set screen lock to "none"
7) copy twrp-pixel-installer-marlin-3.2.0-0.zip to your internal storage
8) reboot bootloader
9) fastboot twrp.img
10) Install: twrp-pixel-installer-marlin-3.2.0-0.zip
11) reboot recovery
12) Install: SR5-SuperSU-v2.82-SR5-20171001224502.zip
13) reboot system
14) profit!
If you knew this, great, if you didn't, you do now :good:

Good Information!
Did you flash a Custom Kernel (ElementalX-P-3.00.zip) or UPDATE-suhide-v1.09-20171001222116.zip to pass SafetyNet?

There are three reasons I recommend #4 - 'Wipe Data' prior to rooting:
a. I write all my guides with step by step instructions for noobs.
b. Some have reported data corruption when not doing #4 - 'Wipe Data'.
c. When upgrading the OS, I always start with a clean install.
If you want to upgrade without a clean installation that's ok too, but it is much easier to trouble shoot problems if you start with a clean installation.

Don't you need stock recovery to be able to apply OTA?
I don't see a step doing that, and I suppose you're on TWRP, or were you already on stock recovery?
If so, then better make that a clear step.

Don't you need stock recovery to be able to apply OTA?
I don't see a step doing that, and I suppose you're on TWRP, or were you already on stock recovery?
If so, then better make that a clear step.

Since boot and recovery are on the same partition, flashing stock boot will give you stock recovery. I flashed my stock boot using TWRP, however, it can be flashed via fastboot as well.
AFAIK, this can be done for all updates (I've used this method since Oreo came out), it's just like taking the OTA from Gooble, you just download it yourself :good:

PS, I did flash full factory image when upgrading from Nougat to Oreo, just FYI

Thanks for the clarification, didn't know that was the case.
I never flashed boot using twrp, would it do it for all slots, I guess it would.

* * * [Pixel 2 XL] - UPDATE Monthly Factory Image / UPGRADE To New OS * * *

WHO IS THIS GUIDE FOR:
Anyone updating factory images within the same OS version (10 to 10)
Anyone upgrading from one OS to another (9x to Android 10)
Below is a QUICK REFERENCE guide for those who have done this before, and a DETAILED STEP BY STEP guide for the first or second timer who needs each and every step outlined. Links to all required files are also provided (make sure you are selecting the latest version)
UPDATE TO THE LATEST FACTORY IMAGE . . . UPGRADE TO THE NEXT OS. . .
PREP WORK:
* Unlocked bootloader. (*performing critical_unlock only required with bootloader versions PRIOR to TMZ20a) read it here.
* Latest SDK Platform Tools found here.
* USB 2.0 & 3.0 cables available (trust me)
* Remove screen lock security before starting
* Remove all substratum overlays
*Download and extract the latest Taimen factory image (place the second extracted folder in Platform Tools folder)
CLEAN FLASH (wipe everything) or DIRTY FLASH (keep data)
Decide now whether you want a fresh OS that will restore your device to factory setup OR if you want to flash the latest factory image but keep your data.
For a clean flash: leave the FLASH-ALL file intact, change nothing.
To retain your data: EDIT the FLASH-ALL file and REMOVE the -w near the end of the script. Save the file and reopen it to ensure the -w has been removed,
When UPGRADING from one OS to another I reco a CLEAN FLASH (leave the -w intact)
Place these files on your sdcard (either before dirty flash or from PC after clean install):
* Latest TWRP.ZIP
* Your preferred customer kernel zip, I use ElementalX kernel
* Magisk uninstall instructions In the event you need to manually uninstall and reinstall MM
* Latest Magisk.zip
* Latest Magisk Manager APK
NOTE: On Android 10, when flashing TWRP Installer, kernels, magisk , etc. in TWRP, ignore the warning "FAILED TO MOUNT '/system' (invalid argument) this is a known issue with TWRP + 10 but affects nothing :good:
QUICK REFERENCE GUIDE for updating/upgrading Pixel 2 XL:
Once you verify 'fastboot devices' on command prompt
Type flash-all to install factory image (allow it to install, and boot into system)
Hold vol down and power button to boot into bootloader
Fastboot into twrp 3.3.0-0.IMG
Flash the twrp installer 3.3.0-0.ZIP,
Flash custom kernel, I use flar2's ElementalX Kernel. SELECT THE CORRECT 9X OR ANDROID 10 KERNEL
Let the system boot up to verify.
Reboot back into twrp and flash latest magisk
Reboot to system
Profit
DETAILED STEP BY STEP GUIDE for updating monthly factory images, or upgrading to the next OS (ie: 9x to 10x)
I reco a CLEAN FLASH (leave the -w intact) when jumping from one OS to a new one (not necessary when doing monthly factory updates within the same OS version)

If you get stuck at the G screen, or bootloop into TWRP, try these steps:
-Perform a hard reboot (long press the power button) or
-Get back to TWRP (whether by booting into it from fastboot, or rebooting into bootloader -long press power & vol down- then boot into recovery) and reinstall the Magisk Uninstaller in TWRP a few times.
- If you are bootlooping into TWRP with Magisk installed, READ THIS!

Make sure you have all the correct and/or latest versions of SDK Tools, factory image, TWRP.img and TWRP.zip, and Magisk
Note: as a matter of superstition, I reboot back into recovery each time after installing TWRP, cust kernel, and magisk, prior to booting into system. It is NOT required, but it works
Again, HUGE thanks to @Badger50 for his invaluable input

Sometimes it takes 5 minutes or so on first boot. If it doesn't work, do a hard restart a few times. If that doesn't work, flash magisk again in twrp.

So your bootloader _critical partition isn't unlocked?? Which can't be right either since you've been able to boot fastboot the update to P. Guess I just don't know what your trying to say.

If you flashed the factory image with no issues, then you must have completed critical_unlock as well, otherwise the new bootloader shouldn't have taken (as far as I understand).
I'd start from scratch again, and make sure you follow the process exactly. Many users have used this with no issue, so maybe you missed something? The first time I flashed the factory image to my 6P (my backup) I totally skipped flashing the boot.img, and wondered why it wouldn't boot

Kudos, just what I needed to update!

Something just seems fishy to me. I've never heard of anyone not unlocking _critical, and being able to fastboot the factory image. However, it seems that you have somehow. All I can suggest is to fastboot the 9.0 again to both slots, and let it boot up each time.
Then fastboot into twrp, flash the installer zip, and let it boot up. Then go back to twrp, flash magisk uninstaller zip, then flash custom kernel, and let it boot up. Then go back to twrp, and flash magisk 1674 again.
If none of that works, I'd unlock _critical, which will wipe your phone, and then start over.

Not mandatory, but it keeps TWRP touch screen working among other things...

Just wanted to say thanks for this!
I didn't have time to update from DP5 yesterday, but I guess that was a good thing because now there's this guide, and it worked perfectly. Upgraded from DP5/flash 2.44 and who knows what Magisk version to all the latest and greatest in no time at all.
Thanks!

Looking for thorough flashing guide

Hi,
Does a thorough guide exist on how to flash custom ROM on this phone?
I have done quite a lot of flashing in my life but can't a ROM flashed for the love of God.
Got TWRP installed, ADB works, cables are good.
Thanks!

After quite some hours I finally managed to get Havoc Pie running (GSI ARM64 AB, downloaded here).
My first problem was the fact that you need to be on stock Oreo before starting, this took me a while to figure out.
I used the most recent 'back to stock' Oreo from this page.
After installing this, I booted up, and went straight for enabling USB-debugging in Developer options.
Then do ADB REBOOT BOOTLOADER to enter fastboot mode.
There I erased system on both A and B partitions by using FASTBOOT ERASE SYSTEM command, then FASTBOOT SET_ACTIVE OTHER to switch to the other partition, and then once more FASTBOOT ERASE SYSTEM to also erase the system on this partition.
After that I ran FASTBOOT FLASH SYSTEM Havoc-OS-v2.0-20181027-GSI-ARM64-AB-Official.img, on the one partition, then FASTBOOT SET_ACTIVE OTHER and after that FASTBOOT FLASH SYSTEM Havoc-OS-v2.0-20181027-GSI-ARM64-AB-Official.img to flash it on the other partition.
After that I installed TWRP by running FASTBOOT FLASH BOOT twrp-3.2.3-0-mata.img (downloadable here).
After that, I rebooted into TWRP recovery by running ADB REBOOT RECOVERY.
There, I put twrp-installer-mata-3.2.3-0.zip (downloadable at the previously mentioned TWRP website) on internal memory and flashed it.
This automatically flashes both A and B partitions (switching between A and B at the reboot screen).
After doing that, I wiped /DATA on both A and B.
Then I put the Havoc-OS-v2.0-20181027-GSI-ARM64-AB-Official.img on internal memory and flashed it on /SYSTEM for both A and B.
Then it is time for GAPPS.
As I prefer Stock GAPPS with my own GAPPS-CONFIG.TXT, I ran into the Error 70: because of the large size of Havoc, there is not enough room for large GAPPS.
So because of that I needed to do the Resize /SYSTEM partition for both A and B (in the Advanced wipe menu section).
After that I was able to flash my Stock GAPPS on both A and B.
Now I need some rest to regain my sanity before I tackle rooting the ROM.
I probably did too much double stuff, but it is not easy to know when only A or B needs to be done.
Comments and tips are welcome.

Wow, here's all i did :
Flashing ProjectTreble GSIs on the Essential using TWRP
1) either boot or fastboot into TWRP
2) Wipe Cache, System, and Data (1 GSI required internal to be wiped, i forget which)
3) From Main Menu, select Install and Flash UN-ZIPPED A/B system.img
4) Reboot Recovery (It's going to say there's no OS, act like you didnt see it.)
5) Reboot System and Enjoy!
6) Most of the later GSIs from October to Present I have flashed and am happy to say
they all contain pre-installed Magisk and ALL but 1 contains Gapps.

Next time i will try your method.
For some reason, if i did anything different, the phone would just keep rebooting into recovery.
And of course, the ROM that i chose (Havoc) did not have Magisk pre-installed.
I am now back to stock and liking it, which says a lot about the PH-1 software!

It does have Magisk installed, it should if its one of the newer builds and all you need to do is install Magisk Manager which in turn activates Magisk

Installing Magisk manager was one of the first things I did, but unfortunately, the latest version A/B Havoc at the aforementioned link did not have Magisk.

There's about 6 or 7 and probably a bunch of YouTube's

Install method explained
Hello!
Since the install steps provided on OP maybe confusing I thought on sharing here the steps I've made in order to get TWRP working....let's call it a "noob friendly guide", ok?
Here he we go:
0 - Your bootloader must be unlocked. If it's not, then follow step 1 of the instructions provided HERE.
1 - Download both twrp-3.3.1-15-laurel_sprout-mauronofrio.img and twrp-3.3.1-15-laurel_sprout-mauronofrio-installer.zip files present on OP
2 - Download latest Magisk Installer, Magisk Uninstaller and Magisk Manager from HERE.
3 - Copy all of the above to your phone internal memory (since current TWRP doesn't allow sdcard nor USB OTG yet...)
4 - Connect the phone to your PC
5 - Reboot to bootloader
Code:
adb reboot bootloader
6 - Check your current active slot
Code:
fastboot getvar current-slot
7 - Flash TWRP image into the current inactive slot (we do this just to leave the current active slot with no changes...at least for now)
If your current active is slot b, then run:
Code:
fastboot --set-active=a
Or, if your current active is slot a, then run:
Code:
fastboot --set-active=b
And afterwards, run:
Code:
fastboot flash boot twrp-3.3.1-15-laurel_sprout-mauronofrio.img
(of course that img file must be on the same path where you have adb and fastboot...)8 - Reboot to TWRP:
Code:
fastboot reboot
NOTE: Long press Vol+ button before hitting "ENTER" and leave it pressed until you see the Android One logo (just to force boot into recovery)
Just a heads up:
Now we are on TWRP booted on the "previously inactive slot". The "previously active slot" continues unchanged. Nothing "bad" really happened until what we decide to do next. If we want, we can just make a TWRP backup of the current slot and nothing else. Afterwards, we could always reboot to bootloader, change to the "previously active slot" again and boot system. If we do this, we continue without TWRP and root but we would now have a TWRP backup of the system present on the "inactive slot". Anyway let's presume you really want to permanently install TWRP and ROOT your device....so let's continue.
9 - While on TWRP, install twrp-3.3.1-15-laurel_sprout-mauronofrio-installer.zip
Note that, by doing this, TWRP will be permanently installed into both slots. This means that, if someday, you want to revert to stock, you'll need to reflash stock boot.img on, at least, one of your slots.10 - After installing TWRP zip, go to reboot menu, change to the active slot (the one you had on the beginning of these steps) and reboot to TWRP
11 - After TWRP reboots, install Magisk installer zip
12 - Finally, reboot to system
13 - Enjoy
Thank you @mauronofrio and Jyotiraditya Panda for your work on bringing TWRP to Mi A3 (laurel_sprout).
I just hope you're able to fix USB OTG and SDCard bugs and, of course, make this TWRP official.
Cheers!

Uninstall method explained (aka revert to stock)
Get boot.img, system.img and vendor.img from your stock ROM build type (EU or Global) and store them on the same folder you have adb and fastboot
Uninstall all Magisk Modules you have installed (do the same for Substratum themes, if any)
Reboot to TWRP
While on TWRP, Flash Magisk Uninstaller Zip
Reboot to bootloader
Code:
fastboot getvar current-slot
(just to make sure which slot is currently active)
Code:
fastboot flash boot boot.img
(from your stock ROM build type)
Code:
fastboot set_active [B]b[/B]
(or a, if you were on slot b)
Code:
fastboot erase boot
Code:
fastboot erase system
Code:
fastboot erase vendor
Code:
fastboot flash vendor vendor.img
(from your stock ROM build type)
Code:
fastboot flash system system.img
(from your stock ROM build type)
Code:
fastboot flash boot boot.img
(from your stock ROM build type)
Code:
fastboot reboot
By doing this your phone will now boot to the previously inactive slot, where an older system build is installed, with all your userdata preserved.
Now you just have to wait for the OTA to arrive and install it in order to have the latest stock Rom build installed without TWRP and Magisk.
NOTE:
This procedure is also intended for everyone that want to install latest stock OTA without losing userdata. The Magisk OTA Installation Tutorial could fail if you tampered with system or vendor partitions, that's why I've decided to share this procedure

There's a way to relock the bootloader???

X2Pro - C.29 Stock to LOS with Magisk

Firstly, I would like to thank @karthick mostwanted for his work and a thumbs up for keeping Lineage OS updated.
I have an Indian Unit of X2 Pro with 128 Gigs of RAM and I got the ROM working with FP and the payment apps at once. Everything works good here. Only thing which I did not like is the camera, so I'm using PixelPlus GCAM on this ROM.
Coming to the steps (assuming ADB & Fastboot drivers installed) -
1. Unlock the Bootloader. For the same Install the In Depth Test app (pm if you do not get the links for the app on Google) and apply. After a successful review message on the app, use the following commands.
adb reboot bootloader (For reboot into fastboot mode)
fastboot flashing unlock
Select the confirmation dialog on the screen and its done. Then type fastboot reboot for the phone OS to boot. It will erase all your data too.
2. Next step is to install TWRP img file by Mauronofrio (Google it). Download vbmeta.img also, you will get in LOS thread downloads section. Copy the recovery file and vbmeta into the ADB folder where the powershell/cmd is running so the you can fetch it. Reboot into the fastboot mode and give the following command.
fastboot flash recovery recoveryfilename.img
DO NOT REBOOT YET. Immediately type fastboot flash --disable-verification vbmeta vbmeta.img and enter. Don't reboot, with help of Volume and power button combination, boot directly into recovery. Remember, do not reboot phone in any other mode or even the present OS because it will wipe the recovery installed.
3. Format Data. (Don't Wipe, Use FORMAT DATA Option). Wipe Cache & Dalvik.
4. Keep the Files in a USB Storage such as Lineage OS, Magisk 20.3, Open Gapps Nano ARM 64.
5. Insert the USB drive through an OTG and go to TWRP mount option and mount external storage. It will start showing files. Now go to install and select OS. Wait, don't run now. Add Gapps to the same queue and then run.
6. After successful installation, wipe cache and dalvik and reboot your phone.
7. After you setup everything, again boot into TWRP recovery and install magisk 20.3.
You are done and all set !
Note - Do not remove/uninstall system apps using root access in LOS, it may break. Happened with me when I tried to uninstall DuckDuckGo, it went into bootloops.
Will be happy to answer any doubts for this installation. Comment below if you need further help !

Do you mean by using apps like titanium backup, systemapp remover or similar?

Did you rooted with new lineage OS 18 ?
