Has anyone tried the ROM from dumbdroid.eu?

Based on Lineage OS 21

I flashed it and it works pretty nice. Google and Vanilla available.

Google version passes basic play integrity (for now)

Don’t know possible bugs, I asked on their discord.

If it’s solid, I’d rather build on top of this then 1.1.1

Didn’t try it, but I’ll tell you from now, pin, Bluetooth, and maybe Wi-Fi don’t work. Period. Everybody, stop falling for those.

Just verified, all three work. Slow boot times though. Haven’t tried with a sim yet.

EDIT: cannot delete pin once set

annnnd bootloops. You are most definitely right.

Anybody ever used this on Verizon? MMS in Google messages?

8

I think it doesn’t work with a sim card…. I’m aiming is like the Android 13 one but I could be wrong

9

Anyone tried the latest version yet?

10

If anyone has any difficulty flashing latest (no space, 1.1.1 boot, etc…)

Here’s a super with latest dumbdroid instead (made by me)

Must erase userdata (and metadata?) post flashing.

Can you patch this rom with your verizon fix? Install Dumbdroid yourself on a compatible device https://dumbdroid.eu/ota/stable/lineage-21.0-20251014-UNOFFICIAL-dumb_gapps30-signed.img.gz

I asked a while ago if anyone tried it with Verizon…

Have you?

13

Yes, not working

14

What works?

What doesn’t work?

15

Doesnt connect to Verizon at all

16

I have to ask. Flashed U.S. bands? Rewrote your IMEI?

If you have time, flash the super below and let me know if there’s any difference.

17

I did not. IMEI did not change US Bands I assume did not change either. I dont believe this touches those partitions.

With the stock 1.1.1 it connected to verizon

No difference with your version.

18

So, just to be clear, you did not flash us bands.

Did you flash anything in-between stock and dumbdroid?

Had us bands “outt of the box”?
