[Q] Strange recurring radio problem

Hi guys, this being one of my first posts here, please tell me if i'm missing some information
Ok so, i've had this radio problem with my HTC Desire for the last 2 or 3 months, the phone randomly disconnects the cell towers and cant connect to mobile data, send or receive sms messages or phone calls.
I've put the logfile in this paste bin having put some comments along the way with it.
well okay i cant link to outside the forum apparently but ill just attach the file then
1. It all starts perfectly fine
Lines 0-30
To this point it works perfectly fine as it sould, but somewhere between then and ~1½ hour, this happens (there are no time logged in the radio logs (or anywhere?) anyways, i turn on the phone from sleep, and notices an notification about android not being able to connect to TDC Mobil and the signal indicator showing a cross above the bars:
2. Then something goes wrong
Lines 33-130
(the last lines repeating them selfs) is me asking the phone for available networks and trying to connect to my operator "TDC Mobil". The phone's display just reads something like could not connect to this network at this time in a toast, and nothing more.
I'm not sure if the phone drops the network when i turn on the phone, but i believe the phone had been without signal for like 30-45 minutes.
So, i change the phone's radio off by turning on airplane mode:
3. I try to fix it
Lines 140-203
When its gone airplane mode i wait a few seconds and removes the airplane mode again, and the phone connects just fine to the cell towers once again:
4. It works again
Lines 208-430
At the moment i'm using adamg's Oxygen 2 RC5 with radio 32.49.00.32u_5.11.05.27.
But i've tried everything, 4 or 5 of the different radios available, the recommended radio adamg suggests and its been a problem since OpenDesire 2 or 3. The same problem persists.
The phone is S-OFF (with the N1Table) and before that the problem also existed. The only thing i can read of the above logs would be some issues about the sim card, if you look then the phone reconnects to the network after coming out of airplane mode theres some sim icc_io errors, should i replace my sim card?
Any help or suggestions are very welcome, and happy new year

changed icc, seems to do the trick

[Q] [SOLVED] T-Mobile G2, no service anywhere, error while searching for networks

I've been struggling with a problem that I just solved in a stupid way so I'm posting to help other googlers.
As I was using my phone recently, I lost service like I had gone into an area devoid of towers, but service never came back. I verified that another TMobile phone (similar plan) found towers and service just fine. I tried everything I could think of from upgrading Cyanogenmod and the radio to reverting to the stock firmware. No matter what I did, the phone would not get signal. When I went to Settings -> Wireless & networks -> Mobile networks -> Network operators I would simply get "Error while searching for networks".
It turns out that the SIM card had seen the end of its days. I went to the TMobile store and had the SIM card switched out for a new one (free) and everything worked again.
The explanation I was given was that old "legacy" SIM cards sometimes will just stop allowing you to connect to the towers with no other symptoms.
TL;DR: If your TMobile (maybe other carriers too) phone isn't connecting to the towers anymore, don't panic. You probably need a new SIM card and you can probably get one for free.

Seeing the exact same problem in the last few days
Found your post by googling the error message - I've got the exact same situation on my G2, the behavior started this last weekend. The phone sometimes connects but is very, very inconsistent. I'm missing almost all text messages, or getting them up to a day late. I guess it's off to a t-mo store for a new SIM card if this doesn't stop. Funny thing is this phone was purchased with a (supposedly) new SIM card - hard to call it "legacy".

Thank you, I just stopped getting service today randomly and nothing I did could get it back. I went in to panic mode and was flashing and wiping and everything I could think of then I saw this post. I didn't think it could work but sure enough it did.

way to be....i learned my fact for the day.

mine just bit the dust.
called t-mobile and they suggested a new SIM as well.
ah well

I had the same issue and after doing tons of troubleshooting i seen that there was a space right under the keyboard that was fully flush with the phone. I lightly pressed until both sides snapped back into place and full service returned. So if you have this issue check to see if there are any spaces open and snap it closed.

Mine has been doing this sporadically, it comes and goes and sometimes I cannot get it to find a service provider. I have to keep doing it over and over and over. Sometimes I have to set phone down and come back in a few minutes to do it again and it finally shows a provider.
The question I have is if you take your phone into Tmobile store to have sim. card replaced do you have to revert phone back to stock G2? Will they say something to you if you are rooted and running CM?

This problem happened to me too and a SIM swap fixed it. They don't check if you are rooted- they might ask you to reboot and change some settings to rule out the obvious stuff like airplane mode, correct carrier, etc.

Maybe not same issue, but also have a soultion for similar issue on G2X
Maybe I didn't have the exact same issue, but I had the exact same symptoms, so throwing my solution up here for other Googlers trying to troubleshoot this as well...
I actually have a G2X, went to Canada where I disabled roaming data and used the t-Mobile wifi calling stuff primarily...
When I got back home to the USA, I couldn't get a signal, but I also didn't have the little x next to the icon... When I went into my settings, I couldn't seem to get the "Use 2G Network" setting to stay off, and of course I couldn't make calls or anything over the mobile network...
So I figured I just needed to force the phone to register on the local network, maybe all the roaming got it mixed up or something, but when I went to the "Network operators" setting, I couldn't "Search Networks" and "Select Automatically" didn't work either, I kept seeing the error "Error while searching for networks".... spent some time playing with libril.so and friends, but it made no difference.
Anyway, long story short, it turns out that there's a setting in the T-Mobile "Wifi Calling" app under "Connection preferences", if you select "Wifi Only", it applies to your setting all the time, even when wifi is disabled, disconnected, and even if the "Wifi Calling" app is disabled too !! So just change that setting back to something else when you're done requiring that behavior and everything will work again, Yay!

I can verify that this is the solution that works. I have the LG G2 w/ T-Mobile. I hadn't had any problems until today. Stumbled upon this thread after the T-Mobile chat support couldn't help me. Went to System Settings and turned wifi calling off completely. Back in business.

Can't find operator

So I am using non rooted, vanilla htc one v. Installed the updates regularly. I didn't messed with my device bcs. it's my work phone.
Yesterday, I had a plane trip back to my country. While I was in plane, afaik the phone was connected to the operator (local operator of other country). I enabled airplane mode and put it in my pocket, didn't turned it off. I did same thing to my wildfire s also.
So I came back to home from airport, put back my original sim card and now it says it can't connect to network. I choose automatically network search and it says error happened, I tried manual search and it only found one operator (vodafone) not the other 2 operators in my country.
I tried resetting the device with factory data reset. Now it can't find any operators at all, and just says error occured when I try to search networks automatically.
I have no clue about how it happened, it's brand new phone not even a month old. I am wondering what should I say to my company and I also wonder what may be the cause.
Anyone have an idea? or maybe solution to try?
edit: It have some problems with wifi also I guess, it disconnects from wifi frequently and shows signal level too low even though my wildfire s shows full bar for wifi.

Take your phone to service center. That's all I can say. There are network issues with One Series bt I think its been solved.

SIM card detected, but "Emergency Calls Only"

Hi. Recently, my signal bars on my phone went blank and I can't get my signal back. I tried to remove/reinsert my SIM card and after a few tries, my phone stopped detecting it altogether. I got a new SIM card, but the problem still persists. Searching for service providers gives several results, but all of them are "unavailable at the moment". Factory reset didn't help either. Please help

If it was working fine and you didn't change anything and all of a sudden you just get no signal, I would first call your service provider and have them check it out, and if they say everything's OK, you should get a new sim, and have them switch the number to it, and if that doesn't work, it's probably a hw failure. The only things you could check on the phone is if you accidentally switched data off, or hit airplane mode, etc.

Airplane mode is off, data is on. I already got a new SIM, but the problem persists. Sadly, I'm not sure I can call my service provider, since I'm studying abroad and I'm yet to learn the language. And I'm really hoping it's not the hardware, it shouldn't be. Also, I don't have signal bars

No Internet Connectivity on my HTC 10 - Please help..

So I got this phone from my Grandpa who recently passed. I was able to insert my AT&T SIM, reboot, and use the phone as normal on 4G+ without any issues what so ever.
Fast foward 24 hours and after rebooting my phone a couple of times and accidentally "Updating Profile" my 3G/4G no longer wants to connect. What's strange is Voice and Text still work as long as the text isn't a MMS since that server is also no longer connecting.
I have confirmed the radio is functioning as I can switch it off, verify it's receiving signal from the nearest WCDMA tower through the 4636 menu.
As well as airplane mode and wifi are working
Sometimes my wifi will not connect first-time unless I "forget this network" and use WPS button on Router to connect - it's like my phone won't authenticate the network once a password is entered. Once connected it stays connected without issue.
Some things I have tried already:
I have attempted to change APN settings to strictly AT&Ts 3G connection - no luck.
I've installed custom ROM, Recovery (Bad Boyz HTC 10 Oreo Stock ROM, TWRP) - no luck.
I've reinstalled stock firmware from HTC RUU - no luck.
Got a new SIM from AT&T and had a tech "diagnose" my phone - no luck.
I've searched all over the internet and found multiple threads about having no signal or no IMEI, but this doesn't completely fit my issue as you can see in my pictures I still have a valid IMEI and cell signal. AT&T said everything is fine on their end regarding my phone, but since it is not an AT&T phone any other support I'm going to have to find elsewhere (Screw AT&T)
The only other thing I can think to try is purchasing a Sunshine license to S-OFF and try manually deleting the radio partitions and then reflashing an older radio or stock radio, but I'd rather not spend $25 for this solution to not work or further complicate my matters.
My question is has anyone experienced this random loss of 4G connection but still have the ability to call and text on their HTC 10? I know this is an older phone, but I really like this phone after using my LG V20 for so long.
UPDATE: Put the SIM in my LG V20 that I was using prior to switching to this device and it is also now having the same issues.... Wtf is going on?
Thanks for any responses!

At your own risk, this:
In the bootloader enter these commands:
fastboot erase modemst1
fastboot erase modemst2
(this will wipe the faulty modem partitions we are about to reset)
