New Update - 34.1004.0204.120 causing constant reboot with AT&T SIM card inserted

[Open1Your1Eyes0]

Installed the update version 34.1004.0204.120 just now and now my phone is constantly rebooting if I have my AT&T SIM card inserted.

If I remove the SIM card everything works, even connecting to WiFi everything works fine. The moment I insert my SIM card back the phone immediately reboots within 15 seconds or so.

Other folks are reporting this issue too on the Zenfone subreddit.

Not sure if it is AT&T specific as someone mentioned with a different SIM card (Tello) everything works fine for them. UPDATE - This seems to be confirmed an issue only with AT&T SIM cards.

This is relatively urgent as I completely can't use my phone right now with my usual SIM card inserted (I'm sure as many others as well).

I was on update version 34.1004.0204.88 just before this and everything was working completely fine since day 1 for me so clearly this update caused the issue, this is not a hardware or unique user data issue.

Some additional things I noted - If I insert the SIM card but the phone is in airplane mode then it doesn't cause the issue. If I have no SIM card inserted and use WiFi it also doesn't cause the issue. But if I insert the SIM card in airplane mode AND connect to WiFi then it keeps on restarting again. If I disconnect WiFi and go in airplane mode (with the SIM card inserted) OR remove the SIM card (and connect to WiFi) then it starts to work again. Seems the issue is related when it is trying to connect to the AT&T network directly (via SIM) or connecting to any WiFi network when AT&T SIM card is inserted. Not sure if this issue is an with other carriers as well but this is what I noticed so far.

I have yet to try a factory reset. I'm not sure if it will work and haven't heard of anyone here trying yet. If they don't issue a fix by EOD tomorrow maybe I'll give it a shot

I read somewhere else that someone did a factory reset and the problem came back eventually. Maybe they meant when it updated again? I'm not sure, so proceed with caution:warning:

I'll wait a few days and see how this plays out. I'm lucky I have a few phones laying around to use in the meantime.

I have similar behavior on my ZF9. I think its specifically related to the Google Play System Update, which is probably bundled in with the ZF update that the ZF10 folks just got.

My phone is behind on the Google Play update (January 2024). If I navigate to the screen that invokes the update (Settings -> Security and Lock Screen -> Google Play System Update), it tells me to restart to apply and then gets stuck in a bootloop. I've been able to get out of the bootloop by quickly turning on airplane mode when it boots.

@Anonymous also experienced something similar with the Google Play Store and posted it in the ROG 8 Bootloop Thread
