SIM not working, no IMEI or IMSI

[TheCrazyDirectioner]

Was just casually using my Amaze today with the official CM10 I've always had on it, and all of a sudden in the middle of a call the call dropped and the phone restarted. I thought it was just a random reboot as they are nightly builds. After it restarted there all of a sudden was no signal. I was a bit confused as just a minute ago before I started the call I was getting full bars on 4G. I tried rebooting multiple times, changing SIM's (the phone is unlocked), even trying different ROMs. All of them had the same problem. No cellular signal. I tried the *#*#4636#*#* to set the network to WCDMA, however it was always stuck on "unknown". No matter what I changed it too it would always reset back to unknown. Then I finally thought I had to resort to an RUU.

After reflashing the Mobilicity RUU (stock one that came with the phone) on gingerbread, the signal FINALLY worked! I was so relieved and went to download the ICS OTA update so I can start flashing ROM's again. Then all of a sudden in the middle of the update the phone restarted, and when it booted back up again, no signal again. I then went to check for software updates again and just wanted to try downloading it over WiFi. I accidentally clicked the phone info screen instead of software updates and I noticed that the IMEI, IMEI SV, Phone Number and IMSI were all "Unknown". This was really odd. *#06* also brought up an empty IMEI box. Then I clicked software update and it said there were no updates available. What? It just worked a while ago before the signal broke again!

I then pulled the SIM out to run the phone WiFi only until I could figure this out and I noticed that it wouldn't say "No SIM" with no SIM card inserted like it normally would, but would continue to say "No Service" as if there was a SIM but there was just no reception in the area.

I've been trying all day to flash multiple RUU's and the only one that fixes the problem is reflashing factory Mobilicity GB RUU. Then signal works again, however after any restart signal will break again and won't work anymore until another RUU reflash. Is there anything I can do? This is the only phone I have to use and it's driving me nuts! Any help would be greatly appreciated!

Please acknowledge that I am not asking for a way to obtain or change my IMEI, as I know that is not allowed. I am asking for a way to fix the No Service issue I've been having.

Now another thing has arises. I try to use it as an iPod/Media player now and just use it connected to WiFi. However the battery dies after about 5 hours of just standby, untouched. It's all because of "Cell Standby" using up battery. It uses up 4 and a half hours of battery and 100% of the time it's without signal. However, even if airplane mode is turned on to disable the cellular radio, it doesn't make any difference to Cell Standby.

I have had this issue twice ... first time it happened maybe 9 months ago and stayed like that for 3 weeks with me constantly flashing and wiping and s-offing no no avail ... one day I pulled out my sim and memory card and when I switched on the device it says "no simcard" it never said that b4 so I switched it off and put back in the sim card and memory card and poof it was suddenly working again...

The first time I recalled not installing anything for months before that event other than one app..... "What's App" I installed what's app and used it fine for 2 weeks and the phone just dropped in the middle of a call and never regained signal.... so I said since that was the only app that I had installed its probably the culprit, so I will never use it again since the phone started working again.

Sadly 7 months later a girl i was talking to kept insisting that I install whats app because she wants to chat more... Against my better judgement I went ahead and did it and it worked for 2 weeks and one morning .... poof "no service" no imei .... and the culprit .....? WHATS APP!!! sadly I have been in this state for a month now with no sign of it fixing itself again... thank you whatsapp... let me know if whatsapp was installed prior to your loss of imei

Actually my Amaze started working again as well! One day around two weeks back all of a sudden it decided to start working again, but I just left it there as I had already bought an Xperia ion to replace it. One day my friend asked if he could borrow it for a week or so, I let him and when I popped his sim in it worked, checked imei, apns, everything was good. However later that day during the lunch hour he took it out and told me there was no signal. First thing I did obviously was check the imei and of course, it had disappeared again. Nothing in window when typing #*06# and in settings imei would say "unknown"

I never used whatsapp before and he doesn't use whatsapp either, it's never been downloaded on the phone so it's not the problem for me. If I reflash GB RUU it will work again and imei will come back BUT only until you reboot, after reboot it will lose imei again. Honestly it seems to have a mind of it's own when it comes to working or not.

Having the same problem too!
Tried removing the sd and sim, rebooting without, reinstalling them, rebooting with, and no luck.
I'm planning to flash the Debloated Stock rom to try that, then I'll try the latest RUU, will report back... (could be a few days)

 

[billteeth]

Debloated stock did not work. Latest ICS RUU did not work. Original, very first, RUU didn't appear to work until I did a restart (without the Sim inserted).
So it's working for now, although it's Gingerbread...

Really? I've tried literally every RUU available for Amaze and still nothing. Before, after flashing a gingerbread RUU the IMEI would work during the first use but would break after restarting. Now when I do any RUU, IMEI won't work under any condition.
