TWRP 3.7.0-12 for Sunfish[Testing]

[RECOVERY] TWRP 3.7.0-12 - TeamWin Recovery Project




Introduction:

Team Win Recovery Project or TWRP for short, is a custom recovery built with ease of use and customization in mind. We started from the ground up by taking AOSP recovery and loading it with the standard recovery options, then added a lot of our own features. It's a fully touch driven user interface , no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

Key Features:

Touchscreen driven with real buttons and drag-to-scroll
XML-based GUI that allows full customization of the layout true theming!
Settings are saved to the sdcard and persist through reboots
Ability to choose which partitions to back up and which to restore
Ability to choose to compress backups now with pigz (multi-core processor support for faster compression times)
Onscreen keyboard
Easy selection of internal/external storage

In addition to the above new features, TWRP features a scripting engine that allows an app to send commands to the recovery for the recovery to perform during startup. We call this scripting engine OpenRecoveryScript. This engine will be put to use immediately in the GooManager app. GooManager will be able to install recoveries automatically for most supported devices. The app will also let you choose to install multiple zips from within Android, wipe, and run a backup.

We are looking for other talented developers, themers, and device maintainers if they are interested in helping with a free, open source project.

Hello, this is a test build for sunfish users.

It has decryption working, touch, adb and backup and restore seems to work. Super partition volumes can be mounted, and the super partition can be backed up.

It's tested FW version RQ1A.RQ1A.210205.004(Feb FW).
I don't test any other FW version.
It doesn't work 'Install Recovery Ramdisk'. It's only for fastboot mode.
I'm working fixing it and build TWRP with June FW.

Andriod10 FW https://drive.google.com/file/d/1PZaU9PpYmdcAHlyi0zhNwEGnBsAHDW_E/view?usp=sharing
It's tested both FW version QD4A.200805.001 and QD4A.200805.003.
And my custom kernel is OK too.

What to backup

What to restore

Repacking TWRP into Boot partition
To repack TWRP into the boot partition to override stock recovery when rebooting to recovery, perform the following steps
1. adb push <latest_twrp_boot.img> /sdcard/
2. reboot to bootloader and fastboot latest boot.img of TWRP
3. Go to Install
4. Touch Install Image
5. Select your TWRP boot.img from /sdcard
6. Install recovery ramdisk
7. Swipe to confirm flash
8. Reboot to recovery and android to verify installation
9. Reinstall magisk, if you want

To install TWRP, you need LZMA support kernel.
My custom kernel is here

Why is there a custom kernel needed?

Because stock kernel doesn't support LZMA ramdisk.
It's needed to install TWRP.

Better to boot vs install until build is proven. Yep, a bit annoying but keeps options open while allowing fluid OTA updates if that's your preference. In boot scenario custom kernel should not be needed.

This is big news and so awesome!

 

[HolyAngel]

Nice!! Congrats on getting it built and posted! Thank you for the mention

Witch FW version you use?

 

[Archangel]

Has anyone used this to create a back up and then restore it properly without problems?

This kernel is good or no?

My apologies if this has been asked/answered before, but could someone ELI5 on why it's so difficult to get custom recoveries running on Pixel devices?

The short answer is - recovery is no longer its own independent partition. Instead it's embedded into boot.img which also contains the kernel for the OS itself.

Recovery used to be its own partition because OS updates looked like this:
- OS downloads new OTA file
- OS boots into recovery
- Recovery installs the OTA
- Reboots back to OS

Now on "A/B" devices OS updates look like this:
- OS boots from "partition A".
- OS downloads new OTA file.
- OS installs OTA on "partition B" which it's not currently booting from.
- OS switches the active partition to B and reboots from that.

No recovery needed anymore. So it's no longer a partition of its own. Which is great for Google but harder for Android do-it-yourselfers.

The only A/B phone I've ever worked on was my Dad's Mi A1, but that had TWRP running just fine.
I remember reading a few things about Project Treble back then, is that related to this?

It's for android 10 version.
I tested QD4A.200805.001 version.
It may work QD4A.200805.003 version(it used same boot.img), but I didn't test.

I used his kernel as a reference, and I added LZMA ramdisk support.
So, his kernel isn't fit TWRP install.

Did you use LZMA compression because the partition where the ram disk is has very little room like the pixel 3A? The pixel 3A did not have enough room in the partition so TWRP was stripped down of features and compressed with LZMA to get it small enough to fit. I believe, but could be wrong, LZMA was used because it yielded the smallest image.

Does the Pixel 4A have the same space issues as the Pixel 3A?
I'm only asking because on the Pixel 3A TWRP never became functional enough to use much because of lack of partition space to reside even after uniquely compressed with LZMA. If the pixel 4A has more space maybe LZMA compression and a specific kernel that requires lcma might not be necessary?

 

[jhill110]

I've never had an a/b phone before and am thinking of getting this one.
A couple of questions :

What is sunfish

Does anyone regret getting this phone

Is it a pain in the azz to deal with a/b

Sorry, I don't know it's needed LZMA compression.
I used pixel4 TWRP made by @bigbiff as a reference, and I used LZMA compression as he did.
