Just a small update. Figured it's a heat problem, and the phone is choosing to disable wireless connections without warning and/or shut itself off. Happens when I fast charge, play games, or even just bring it into a hot room. It also seems to heat up slightly even when just browsing the web for a while, and then just locks the sim card out of nowhere.
That's an really interesting point. Maybe we damaged the temperature sensor by replacing the screen? I do not even know where it is set?
Putting it under a fan works for me.
I don't think so. I had the issues before replacing the screen. But I was in the hope that maybe if I reconnect the battery it would fix it. I could give a new battery a try. It could really be that part. I think since mobile phones exist the first thing that got damaged was always the battery.
Mhm... That refutes our theroy... But I'll try though. I've already ordered a new battery. There are some improved batterys on the market. So i ordered a 5300mAh one. But it takes about a month for delivery I think. Meanwhile I'll place the phone in the fridge as said before and will test this method.
.This is also interesting. I'll check my baseband. I don't know if it's also gone. But goodthing we have a guide to restore it. But I think its the battery. It's more than just a battery as I learned already.I have DevCheck installed on my phone so I can read temperature. Battery is in good condition, when fully charge and plugged into dc it's 32C. I'm preparing to install RUU. If this won't happened then I'll stick with my Alcatel 1s 2019 for replacement for longer period than few days
After installing RUU problem is not solved. "com.android.phone is not responding". So now I cannot install anything without wifi. So after almost 3 years phone is useless.
Baseband is still unknown. And I think this is the issue here. But how we can repair that I don't know for now.
Don't do factory reset if baseband is gone. I did it and it won't help. I'll give feedback if baseband restore will help. If yes, then it's good to go, if no then...My U11 also suddenly hit this issue yesterday afternoon while the phone was just lying on the table. One minute it was working just fine (I was on my laptop chatting via whatsapp web linked to the phone), next minute both SIM card not detected, wifi cannot turn on, IMEI & baseband gone. If I tried to enter Mobile Data option in setting, a popup com.android.phone ANR appeared. Tried everything except Factory Reset but no use. What did actually happened?? The phone wasn't even overheated or fell down. It was almost 3 years (purchased on Dec 2017) but so far never got any problem, not even lagging, there's not even a crack in the body.... Very2 frustrating
Please share any updates on the issue.. in the meantime I shall backup everything first and tried the factory reset sometime tonight. Thanks in advance!
Thanks a lot for saving me from major headache of factory reset! Looking forward on the baseband restore outcome.
Welp, not the update I'd like to give, and certainly not the outcome I would prefer, but my WiFi and mobile signal is not coming back regardless of CPU and battery temp.
I'm using this tool "gnirehtet" to reverse thether internet connection from my PC to the phone via USB cable. This way we can make file backup to PC, and cloud backup on the apps directly from the phone. For cloud backup I just use the good old Helium app.So, any apps I can use to transfer data to another Android via USB only?
