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.

Hi @Mansi_ASUS - Do we have any status update on the fix? It's been 5 full days people are down without their phones now (or stuck on WiFi).

It's been close to two weeks for the ROG 7 people 😞 I'm getting tired of having a half useless Zenfone 10... especially since I've been working on my newly closed house where I don't have Internet at bcuz I'm still living at my other place of rent for the time being.

Wow that's pretty crazy! Really disappointed in how slow ASUS is handling working on this fix considering the urgency of the issue for AT&T users. The least they could do is at least release an update that forces it back to the previous version when everything was working while they sort out a fix for the new one, but for some reason they can't or don't want to do that. I guess the wait continues... 😔

Everyone, apparently @Mansi_ASUS has responded to a new Zenfone 9 boot loop thread, stating that the R&D Team has found the problem and is working on a fix as of 7 hours ago from typing this.

This is great news! Finally we have an update. Makes me feel a little more confident now that we may not actually have to wait forever for the fix lol. 🙂
