Greetings,
I have read alot about this problem on the interent, I have contaced HTC for this and I got no suitable answer they keep asking me strange questions about how do I operate my mobile, This is my 6th android mobile since 2009 and I never saw a problem like this which I cant switch to 3G mode, the option is grayed and I cant force to change it even throught "phone information" from GSM Only to WCMDA prefered, tried both sim slots, tried another sim, tried some google play apps, tried factory reset... none did work out.
I did also read about an update to HTC 820 software which was applied to "some HTC 820" that would reslove this problem, but my phone wouldnt get that update.
Now the question is, Do i try and apply a RUU from HTC which is not mine? since my mobile is Indian and I think gettings a chinese RUU might solve the problem.
please advice.
thank you

Hello.
Since yesterday I can't get any reception from my HTC Desire. All it says is "Limited Service, emergency calls only".
It seems to come from my phone apparently.
I have a HTC Desire branded Orange (France) and I flashed the official HTC Desire rom on it then updated to Froyo via update.zip.
It worked fine until now.
I tried flashing 3 other radio, including the orange one, but it doesn't change anything.
Tried wipe data factory too, nothing more.
Can anybody help me please?
Did you flash anything before you werent getting signal or did it just randomly go? Tried searching for networks manually? You should be able to get the joint Orange T-Mobile network.
I didn't flash anything. The only thing I did was update an app via Market.
Searching network manually never end, it keeps searching again and again.
I tried with another sim card and it works.
Thank you

is the sim card for the same network? your provider will be able to just swap info on it , so that sim card becomes your old one
Yes it is.
I will try to check with them when I get off work.
Thank you.
Dear All
first of all, sorry for my bad language.
my problem started when i purchased an used Inc2 from swappa, i am expert in flashing ROMs for HTC phones.
when i got the phone, i s-off, installed recovery and installed custom ROM supports GSM, as i am living outside USA, and everything was good (GSM and data)
one day, suddenly the phone was not able to get a H data, only E, so i decided to factory reset to solve the problem, i return to stock ROM using RUU, then when i turn it on for the first time i discovered that its still connected to verizon Network and gave me a roaming signal, i know nothing about verizon network or how to disconnect my phone from their service.
don't tell me to contact the original owner, because i purchased this phone more than one year ago and i totally forgot from whom i toke it.
THE MAIN PROBLEM NOW, every time i insert my local SIM, the phone switch from roaming mode (CMDA) to global mode (GSM), which is OK, but when i receive or make a call, it restarts automatically !!!!
i had tried all the ROM, RUU, radios in the development section, with no hope, so, i think the problem is occur from the conflict between CMDA signal an GSM signal!!!???!! or something else, so i guess the first thing i have to do is disconnect the verizon service, BUT HOW?? somebody please help me
any thoughts folks?
Can you post your phone's settings, mainly the ones under "About Phone" including kernel, mobile network type, service state & software information, etc.?
With a local Sim card, it is possible that you device would boot up & switch to Global Mode (by default) with preference for CDMA, but you should be able to manually change it & semi-lock it to GSM only? What happens when you tried that?
There is a # of GSM only Rom that you can flash, assuming you've rooted it again & maintained S-Off with a custom recovery re-installed - and, that it was properly Sim unlocked.
Im on GSM with chilly's beanstalk 1.30 (4.2.2) and I have no problems, check if a wipe with antivenomSDW, helps.

You will need to flash a radio/baseband that matches your cid. Mismatched radio baseband can cause all connectivity to fail. If you don't want to modify your phone, that's your only option. Sorry.

Flash cyanogenmod, do the baseband change again. Switch to automatic. Only cyanogenmod has the automatic network selection option. Stock rom don't have.
This is the only way as I also experienced the same.

I have a oneplus two and went through the same problem . I read a lot of threads on various sites and found that this question remains unanswered. Very disappointing .I was tinkering just to find something to make my sim work . Fortunately ,I found the fix.Its very easy and a person like me who doesn't even know how to root a phone can solve this problem .
Solution.
Wipe data and cache.
Download the latest stock ROM available and flash it .
Type *#*#4636#*#*. Go in phone information.Open options . Select radio band 40. Just don't select USA.
Download Shortcut Manager lite.
Search engineering mode.(search 'eng')
Scroll down to find
com.android.engineeringmode.network.BandMode
And
com.android.engineeringmode.network.BandMode2.
Find 'Auto' option after opening one of the bandmodes.
The sim should start working.
If the sim doesn't start working , change band and reselect Auto . This should do.
PS. If u don't have any other radio band than USA then try these repairs on USA band . Hope it works. If this works please share this info on other sites and help people.
Cheers !
Anyone found any solution, I am facing same problem after changing radio band from phone test menu.

Am facing the same problem but with D816w, you see, my device is a Vietnam source (HTC_059) and after receiving the Android 6 update I lost my IMEI numbers due to Unkown Baseband, after some research I did find Android 5 Firmware which is compatible with my CID, I have restored my Baseband with IMEI along but with no Coverage, when i go to *#*#4636#*#* am only left with Automatic band , NO USA No Europ No African or even ASIA,
My device is rooted but with S-ON , anyone can help me with that?
Hi all, I've been battling this problem for days now. Airplanr mode is stuck 'Turning off...' and wont connect to my mobile carrier. Things I've tried:
Restarting phone with and without SIM inserted
Factory reset from settings
Factory reset from recovery mode
Flashed to the same build twice using the flash from SD card method (build 3.36.709.3)
Turned airplane mode on and off with wifi/mobile data/NFC turned on or off
I have no idea what to do next. I doubt it's a hardware problem as the phone detects the sim card when I put it in and asks if it's O2 pay and go or pay monthly, so it can even read it, it's just the phone wont come out of airplane mode.
I am on holiday without a PC but feel free to post ideas that requires one. Device is currently S-on and unrooted. I would rather not root or s-off the device just yet, and would rather stay on stock ROM as it's still in warranty. Problem is, it's in the UK and the warranty is held in Taiwan, which means sending it internationally to get it fixed. It's also a problem as there is a language barrier between me and their support for phone calls and their live chat button appears to always be greyed out.
Edit: I found this for the M8 which I think is in the right direction:
"Even I started thinking same way but it wasn't hardware issue.
I used ##786# to reset the phone completly (it did asked me my MSL/SPC) and everything was wiped from the phone. ( I am sure this reset is different from normal factory reset)
now my phone is up and I can toggle Airplane Mode On & Off however now there is another thing which I came accross
1. No roaming option or extended options in "Mobile Data" option under Wireless & Settings
2. No Network Sharing option
Even tried after running RUU_M8_WHL_K44_SENSE60_SPCS_MR_Sprint_WWE_Harman_2 .16.654.4_R2_Radio_1.08.20.0612_4_NV_SPCS_1.52_003 _release_384670_signed_2"
How do I do this with the M9? aLogcat comes back with no MSL so I need a free unrooted way to get that, and that # code doesn't do anything on the M9 either!
Edit2: Tried*#*#4636#*#*
Option is there to turn on the radio, but pressing it does nothing. Changing preffered network type does nothing either (I select any option from the drop down and the original choice remains). SIM is with O2. Currently set to GSM/WCDMA/LTE
Please help -_-
damn you really tried an m8 RUU on M9? please don't be stupid! it will never work lol. is your phone unlocked, so you could flash twrp recovery? otherwise you need to find a RUU matching your mainversion/CID. but this time not from m8 lol

The M8 RUU was a quote from someone having the same issue on their M8. Sorry if that wasn't very clear. I am running a fresh M9 latest RUU, I'm not dumb enough to put an M8 RUU on it and the stock flash utility (download mode) isn't either.
I still haven't found a solution to this. Can anyone help?
tried in *#*#4636#*#* on the menu button the frequency option? if you are fully stock, ask HTC, if they have no other fix, send it for warranty
I've tried everything in that screen. Here is what I have also tried today:
Bootloader unlocked
Custom recovery installed
Rooted
Model number and CID changed to developer model
Developer rom installed (android lollipop) same problem
Latest developer edition firmware installed
ViperOne 4.3 installed, same problem
Cryno... Something... I forget the name, but another custom rom installed, same problem.
It's fair to say that the problem is probably hardware related. The SIM card is detected, but the radio willnot turn on. In this instance, what is the most likely hardware cause? Is it worth replacing the sim card reader or is it more likely to be a chipset issue? I would be happier replacing the sim reader if the sim was not detected at all.
Btw, all the custom software stuff was done because HTC Taiwan said they wouldn't touch it. According to them it's out of warranty even though UK support say it's in warranty with the taiwan support centre.
Hi all
Ok I have searched around the internet and the problem I have is my settings for internet dont save. It just says it did but does not. Resetted the phone cleared it and no joy. O2 have said they cant send a text message to update the phone i am not sure why. I have read that this happens with o2 sometimes and cant find a solution. The GSM works fine but not the 4g.
I can put my other sim card in like vodafone and EE, it works fine. Anyhow it's on android 7 and the last thing I want to try is put stock android but I don't know how to do that as it might be glitch on the android system files.
The problem is strange as it only does this with o2 but not with other sim cards as you don't need to go and manually put internet settings in. Even if you did manually put it in does the same thing... as it says saved and then does not.
I have updated a samsung with Odin and a guide off sammobiles site but not sure what the HTC secondary official site is, as I want the original rom and how to install it.
Any help would be nice.
Thanks
When you insert the sim card you should get prompted for O2 payg or O2 monthly etc.. If you don't get a prompt then it could be a simcard issue. Does the O2 sim work as it should in any other device?
Beamed in by telepathy.
Stock roms can be found (together with flashing instructions) in the ReadMe thread. Take a look at the RUU section of the thread.
