LineageOS finally boots on realme GT 2 pro 😍💫

realme GT 2 Pro Fundraising update

So far we have collected ~100 USD and the development has been progressing well considering we were able to unbrick devices with TWRP, custom roms to boot and custom kernels to work as well. Things would go much faster if people can contribute small amounts for my work which would help me test things first hand and make things stable quickly.

Almost everything works with LineageOS except for

Issues :

* Recovery doesnt boot with oss kernel modules (So ,we have to flash custom made vendor_boot to access recovery)
* FOD flickers when used

Otherwise everything from charging control to gestures to all basic features work fine incl payment apps

Contributors can PM me if you would like to test initial builds.

As for crowdfunding status, ~110 USD is collected so far achieveing 1/3rd of the target goal. Kindly contribute if you are planning to use custom ROMs.

Common tree is now opensource since it would help other oplus devices with same soc.

We now have usable stable builds of lineage OS where almost all features work with a few bugs

* Recovery doesn't boot with OSS kernel modules, so you have to flash custom vendor_boot
* FOD flickers when used

If you have contributed to the fundraising and if you wish to get access to the builds, let me know via PM.

Fundraising status:

We have crossed the 200$ mark for the purchase of the device for development. The current builds seem good enough for daily usage without much issues although there is a tiny bit of bug fixing to do.

Check here for the current status:

Remaining funds needed to reach the crowdfunding goal
INR : 9174
USD : 111.89

Fundraising Update :

Thanks to each and every one of you who contributed towards custom ROM development. We have reached our target goal of 26000 INR and you can check the crowdfunding status here in this spreadsheet.

As for the current status of the development : Almost each and every basic features work. The bug list includes :
* FOD flickers when used
* Random video playback issues
* Stock cam app crashes randomly
* Occasional freezes (Rare)
* NFC is yet to be fully tested

Apart from these issues, everything else works fine and the other software features like pickup sensor, touch gestures, double tap to wake, high touch polling, auto high brightness mode, screen off FOD works fine.

Credits :

* Credits to lineage OS team for their work on previous devices
* Credits to @grewal and @Chandu_Dyavanapelli for their work on oneplus11R and oneplus 11
* Special credits to early testers @Veyssso @PS_DEV @DrM0_Elaa who did brick several times and had to spend their own funds on unbricking their devices

The community did a great job the past few days and had an important part in encouraging others to contribute towards making this a success. It's 2023 and digital hygiene should be a thing and i'm hoping the trend grows in the future too.

Guide to using adb and fastboot/ Installing onto Windows PC ( Universal guide )

🗝 Download Platform tools from Google

Adding it to system environment variables
1. Search "system environment variables" on the famous windows search bar in desktop
2. Click on Environment variables
3. Select "Path" and click "Edit"
4. On a separate line, add C:\platform-tools (Making sure the platform tools you downloaded is copied on that directory)
5. Save and exit
* Now you will be able to access fastboot and adb just by opening cmd prompt without going to that exact directory of platform tools

🧨Minimal adb and fastboot 🧨
Its old and made in 2017, ofcourse it doesnt work reliably for dynamic partition devices. Uninstall it before you perform the above steps.

Common commands that can be used with this tool for dynamic devices:

1. Basics
Note : fastboot and fastbootD are different. fastboot has limited functionality whereas fastbootD can do a variety of things. You can flash GSI only via fastbootd.
fastboot = fastbootd
bootloader = fastboot

adb reboot bootloader and fastboot reboot bootloader takes you to fastboot
adb reboot fastboot and fastboot reboot fastboot takes you to fastbootd
Similarly, adb reboot recovery and fastboot reboot recovery takes you to recovery

You should be able to flash only boot,dtbo,vendor and vendor_boot from fastboot
You can flash everything via fastbootd

2. Fastboot boot
This command can be used to temporarily boot the provided Image.

sm8350 devices come with virtual AB and has recovery in the boot partition (No dedicated recovery partition) or vendor_boot partition as recovery.

sm8450 devices and later have dedicated recovery partition, so you can flash recovery image using
fastboot flash recovery recovery.img

* All mediatek virtual AB devices has this feature broken and during such exceptions, you have no other option but to flash bootimage.

3. Switching slots
fastboot getvar all
This will give you a  long list and near the end should be your current-slot : Either A or B or you can simply execute
fastboot getvar current-slot

If by any chance your current slot is not working properly- bootloop or any other issue, you can try switching slots with this command
fastboot --set-active=b ( if your current slot is A) and vice versa

4. Formatting your data
Caution : This deletes all your personal data
If rebooting the device automatically boots into recovery, you might have to format all your data. "Format data" option in recovery is superior to doing fastboot -w in fastboot or fastbootd

5. Flashing partitions
GSIs are system images which can be flashed with this command
fastboot flash system system.img

Flashing any other partition
fastboot flash {name of the partition} {path to the partition image}

🔸Tip : If you flash dtbo manually, flash vendor_boot too else it might not boot

6. Deleting and recreating partitions
Example :
fastboot delete-logical-partition product_a
fastboot create-logical-partition product_a 0 # Zero is the partition size and it resizes when an image is flashed.
