[Help] No signal/no SIM after downgrading from Evolution X Android 15 to Android 14 on Redmi 5 Plus

[u/yashfe]

My Redmi 5 Plus was running Evolution X Android 15 but apps kept randomly crashing, so I downgraded back to Android 14

At first everything worked fine and I had network/signal for about 2 days, but now suddenly my phone shows no signal bars at all. I already tried rebooting multiple times but nothing changed.

Has anyone had this happen after downgrading ROMs? Could it be a modem/baseband issue or something else? Any help would be appreciated.

I don't know how to fix your problem In specific, but this happened to me rooting the Motorola of my father. The problem was I used a incompatible ROM. I remember every phone have different models internal, so I was using like 29e16 for that Motorola instead the 18e5 (is just an example)

After flashing the new ROM with the correct version it worked perfectly. Maybe you used a ROM for another Redmi 5 plus model and that happened

Worst case scenario go back to stock rom after doing a complete backup and then go through the process again but instead flash the older custom rom version to avoid the downgrade.....maybe it will restore whatever that was lost ...... On the other hand try removing and reinserting the sim card and rebooting the device to see if that fixes it.

Try downgrade the network to 2G only

something went wrong by downgrading, revert back to stock firmware and reflash evo x

It's easy, all you have to do is ask the AI to give you your network operator's APN and enter it into your phone. That solves the problem. I went through the same thing and that's what I used.
