Question Lenovo Legion Y70 custom roms tested and working GSIs - Lenovo Legion Phone Duel 2

Since the Lenovo Legion Y70 doesn't have it's own section, I'm posting this here.
The Legion Y70 unfortunately doesn't have a global rom, only CN. Luckily, it ships with the bootloader unlockable straight out of the box. I've tested several GSIs listed here, and they all work! This phone is great value considering the high end specs, so it's great to know we can install customs roms on it.
No hardware issues aside from adaptive brightness; doesn't work because the GSIs are missing the device overlay.
vndklite images do not boot! Just the ARM64-ab images boot (non-vndklite).
I've tested the following GSIs:
Lineage 20 (Andy Yan)
PHHusson Android 12.1
TrebleDroid 13
Pixel Experience
All working with some bugs. Namely SMS and phone calls randomly stop working!

Unfortunately no, there is no option for it in the GSI rom.

I know, but this is a very early version

I think this phone deserves its own section for easy communication because the foreign community about this phone is quite small. Also, I cannot find any guide or tips so would be great if someone put a tutorial to guide some newbies like me on how to install new ROM or other amazing stuff. Btw, I tried to unlock my Lenovo legion y70 by enabling OEM unlocking in the developer setting and trying to access fast boot but I saw that my phone state is still locked, not sure why. This phone is high value and has good specs so I'd love to see if the global community can grow bigger

checking the OEM unlocking option simply allows you to unlock the bootloader.
To actually unlock it, you need to do so via fastboot:
1. Restart the phone into Fastboot mode via the command: adb reboot fastboot. You should now be in fastbootd mode.
2. Type command: fastboot flashing unlock
3. Then type command: fastboot flash unlock_critical

Is there a way to create a section for this phone? I hope we can install stable roms to get the most out of the device

I've tried Lineage 20 (Andy Yan) & evolution X, both of them can't receive texts. Everything else works great.

oh thanks, this issue is what I am searching for, thought that's because of hardware issue. I am using Pixel Experience plus, phone not receving SMS text but somehow it received in bunch then not anymore.
If anyone know how to fix this, please kindly advise.
Thank you

Hi, what version of pixel experience plus are you using?
I looked on the official website and didn't find anything about the lenovo Y70...
Could you describe step by step how you installed this rom?

Hi, I am using the latest version of PE GSI rom here: https://github.com/ponces/treble_build_pe/releases
There is no official Custom ROM for Y70, however, we can use GSI Rom for any Treble compatible device.
These are my notes for step-by-step installation, do it at your own risk:
Install GSI Rom: Copy GSI rom (only use vanila arm64-ab version) file to “platform tools” folder and rename to “system”:
./fastboot reboot fastboot
Then, enter Fastbootd mode on phone (by pressing power off + Vol down)
./fastboot flash system system.img
./fastboot -w
./fastboot reboot

Is there anyone using GSI ROM on Y70 can receive SMS text?

I also have this issue. I'm able to send SMS text messages, but not receive them. This was an issue with Android 10 GSIs, thought it was fixed... Looks like it's still an issue.
I'm trying to find what the solution was for those who had this problem before on other phones.
I tried PHH Treble settings --> IMS features --> Install IMS APK for Qualcomm S+ vendor and request IMS network options but neither work.

after trying endless scenarios, I can conclude this issue is related to LTE.
I have to reset network and check if 3G is enabled instead of LTE, then rebooting. The flaws are that I cannot use LTE and this solution only work for 2nd sim slot

Does it work on legion 2 pro?

Can confirm receiving text messages is now working. I did the following (same fix as other phones on GSI)
I don't know what fixed it exactly, it's possible only 1 of the below actions fixed it:
1. put my sim card in tray 2 instead of 1
2. In settings --> PHH Treble settings --> IMS Features --> Create IMS APN
3. In settings --> PHH Treble settings --> IMS Features --> Install IMS APK. Click it, then install the downloaded APK
4. In settings --> PHH Treble settings --> IMS Features --> Check Request IMS Network
5. In settings --> Network and Internet --> SIMs --> Preferred network type: 3G
Reboot
After doing the above, SMS text messaging is now working both sending and receiving.
As mentioned, it's possible only 1 of the above settings fixed it but now that it's working, I don't want to change anything because I'm using it as my daily driver.
