[Xiaomi Redmi 3s ROMs, Kernels, Recoveries, & Other] Krishna1204:
The OP has mentioned the procedure for installation but I'll just elaborate it a bit more from my experience of trial and error while installing the firmware. First of all, as in the OP, you can find the original thread and universal GSI (by [MENTION=8302434]fxsheep[/MENTION]) and the GSI created by [MENTION=6757262]Abhijeet Rajgor[/MENTION] specifically for land. I installed both ROMs by both methods, universal GSI by the method mentioned by [MENTION=8302434]fxsheep[/MENTION] and this land GSI by the method advised by [MENTION=6757262]Abhijeet Rajgor[/MENTION]. I also installed the universal GSI by Abhijeet's method.

So here it is:

1st attempt: Universal GSI by original fxsheep's method:

1. Download the universal GSI .zip file from the original thread by [MENTION=8302434]fxsheep[/MENTION] and unzip it.

2. Download treble twrp(I used 3.2.1-0) and treble Android 8.1 ROM (Carbon ROM)

3. Flash recovery. and ROM. Create a backup of any partition through twrp (Just for the location where you have to place the GSI files). Boot.

4. Now transfer the files of the zip file into TWRP/BACKUPS/(your phone's serial number)/(date and time of backup)/

5. Reboot to recovery. Mount everything except USB OTG and Micro SD card. Go to restore and swipe to begin restore. Done. (I referred this from the original thread.)

What I got: Fastboot.:( Yes. That's it. No matter how many time i tried to reboot, all I could get to was fastboot. I even repeated the procedure, but the result was same. I learned form somewhere that it maybe due to vendor partition.

2nd attempt: Universal GSI with Abhijeet's method.

1. For this to work i downloaded the boot, vendor, modem folder from the OP and pasted the files in the universal GSI folder.

2. I fastboot flashed stock miui 8.8.23 and flashed treble twrp, but for some reason my phone didn't boot after that.:rolleyes:. I tried with non-treble twrp (of course after fastboot flashing the ROM again cause flashing .zip of stock miui didn't seem to help:laugh:), but the phone still didn't boot up. So i booted to recovery, transferred the carbon rom through adb and flashed it. The phone booted.:good:

3. Again took a backup of boot partition, booted, transferred the fxsheep and abhijeet combined files to the backup folder, booted to twrp, and restored vendor, boot and system. And then, :victory: there i was at the MIUI 10 welcome screen.

3rd attempt (just testing): Land GSI with Abhijeet's method: The procedure was the same as 2nd attempt (minus the repeated fastboot flashing as i restored the GSI over the universal GSI).

Now, for the comparison of both images and my review.

1. Screen flickering, brightness bug and camera issue (due to screen flickering) exists in both. But that's not a big deal as gcam works flawlessly, even better than i have found them to work on some AOSP based ROMs. I used GCam by tolyan v5.1 test 1.4

2. VoLte works perfectly.:good:

3. I own a 2g/16g Redmi 3S, so I can't comment on FP working.:silly:

4. FSG works nicely, except there is some lag in swipe up to home and recents in both ROMs (nothing like a dealbreaker).

5. Both ROMs are fluid without any stutters while navigating through the phone though didn't play any games or anything. but I think they'll play fine.:D

6. The status bar is too thick to be comfortable (atleast for me).

Advantages of Universal GSI over Land GSi:

1. App Vault works. It doesn't in the Land GSI.:confused:

Advantages of Land GSI over Universal GSI:

1. Google Play Store is preinstalled.

2, You get an advanced boot menu.:cool:

The screen flickering issue is fairly irritating. And, I couldn't root the phone with magisk 17.1 and 16.6; got stuck at "Constructing environment". It was about 1 and a half hour before i force rebooted the phone and it booted normally.:confused:. In my opinion, this is a great initial version and only if the screen flickering issue can be solved, it can be an easy recommendation for a daily driver. So I'll be waiting for a more stable build, till then reverting back to PE Pie. Many thanks to both devs, [MENTION=8302434]fxsheep[/MENTION] and [MENTION=6757262]Abhijeet Rajgor[/MENTION] for this ROMs.:cool:

Edit: Just some grammar and spelling here and there. It's a long post.:rolleyes:
