If you have converted to international for all intents and purposes you now have a GSM1917 international. You can install Derpfest and all the other "regular roms". If you do the "manual method" where you flash each partition you should be good to go.

I'm also having this issue.

And unfortunately there's no way to get TWRP on Android 11 at the moment. Not sure about how else to go about flashing

Not true anymore. If this rom uses "fbev2" which apparently most true android 11 rom's do then nebrassy released a version a couple of days back that works just fine with android 11....I linked to it in the derpfest thread and posted install instructions which should work here as well. Even if you get twrp installed you probably still don't want to install the rom's via twrp...just do manual method and then use twrp for backup's etc.

Would it be possible for you to link me to the source of that TWRP build? I would like to get it on my phone.
Also, that would allow me to build a flashable zip of this firmware.

I found nebrassy's twrp image, but it still does not support decryption.
Also, when I booted to it, it messed up my entire system. The phone was no longer able to boot to android and when I reflashed my boot image it started crashing on boot.

I am looking into how to get this working properly.

If you didn't find the post where he specifically says "here is the fbev2 version" then you didn't install the right one. He has SEVERAL versions of twrp.

yeah, that says "only use if you are on a custom rom and other builds dont work for you"
it ended up soft-bricking my phone
Both Derpfest and Yaap work well with fbev2 and are Android 11 based on AOSP. I'm sorry that happened to you. In future you should use "Fastboot BOOT twrp.img" to boot recovery without replacing the existing recovery...then if it didn't work all you'd need to do if force the phone to power off via holding down vol up and power for several seconds. Still not sure how you soft bricked because I tried installing it in recovery on a non compatible rom and all it did was startup and show available storage as 0. It showed no files...once i upgraded the rom then it worked fine.

If you pay attention to with slot you are booting to and flashing to ,it will help out slot. This will always leave you a option to repair. By just switching to the opposite slot to boot to recovery. If you don't know the command then you should really learn fastboot --help. It's all the same as Python.

Hi, do you have the 11.0.1.3 update as well ? I can't install it through OTA, installation keeps failing for whatever reason...
I have the extracted payload, but im not sure if it's actually usable on the GM1915. I can upload it if you need it, but there are several partitions you cant flash and the system image is not in the proper sparse format.

    Hi, do you have the 11.0.1.3 update as well ? I can't install it through OTA, installation keeps failing for whatever reason...
    I have the extracted payload, but im not sure if it's actually usable on the GM1915. I can upload it if you need it, but there are several partitions you cant flash and the system image is not in the proper sparse format.

    Hey guys. So if this is a tmo 1915 converted thread, maybe you can help me.
    Have anyone tried this rom? Because I have OTA 11.0.2.1 installed on my 1915 and 90hz and QHD make blackscreens and zoom in my lockcreen.
    Do you have same issues on your phone?
    this is another thread with the same issue
