I live in Bangladesh. Recently I visited Malaysia and bought a Dopod 838 Pro from there. I checked it over there and it worked fine. But after getting back, when I tried the mobile with my country's SIM, it gave a error message saying ' your current network 47001 is not supported, please ask your device vendor for an update' and I got a no service problem. In the available networks section my operator (GrameenPhone) isn't listed.I tried almost everything I could, upgraded to SPL v.7, tried different radio versions, tried different ROMs and modified windows mobile versions like Black version, Pays version etc. The best I got was I got a signal for 2-3 mins. During that time I could make and receive phone calls, it worked fine for that short time. But after that 2-3 mins. the signal drops and the phone starts checking for the signal and eventually I get a no service problem. I tried repeatedly but with the same result. This is so frustrating!!!! I love the phone, how can I make it work?? Hey guys, help me out please. Thanks.

Have you tried to SIM unlock it?? Take a look in the upgrading forum...READ READ READ before doing anything else ok?
Try a different more newer SIM card, or maybe a different provider!
Re:
Tried unlocking, different provider, different SIMs, everything I could think of but alas nothing worked. Any other ideas guys??
Still no luck guys!!
Hey guys, I'm still stuck with my problem here, appreciate your help. And I also need the radio ROM version 1.40.30.00 (that's the only radio ROM I couldn't try because when I clicked on the link shown in the forum I got a '550 Failed to change directory' error. Could someone plz re-opload the radio ROM somewhere and send me the link. Thanks.
Phone problems
Make sure you are SIM unlocked and not just Device unlocked. They are two different things. I've heard of some folks having to repeat the process a few times for it to "take". Good luck.
Hmmm... If an IMEI is reported as stolen etc would it cause the phone to work for a couple of minutes and than lose service? This may be something for you to check into. Just my 2 cents.
Hi there
Ok starting from the start.
My phone is not rooted (it is still s-on).
The phone was bought on ebay a couple months ago.
It has been working fine.
Yesterday, when pressing the power button to unlock, the lights came on but the screen did not.
This happened a number of times after rebooting the phone, then eventually it randomly came on again.
However, the signal, never came back. The phone thinks it's in 'airplane mode' when I press call. There is no airplane icon up top. I have turned airplane mode on and off each way, rebooted, hard reset and cleared all the data from sd card and phone. Wifi works, but signal is still 0.
Still same problem.
When pressing further, I noticed in the 'About' section of the phone, that the BASEBAND is UNKNOWN! So is the imei number etc.
I did a few google searches and couldn't find much; although it was suggested that I reflash the stock rom. I am unsure how to do this.
Please could somebody point me in the right direction, because I am panicing here.
Thanks very much

You can use the European version in Canada as well just fine if you happen to be here.
I flashed it to upgrade my radio version to get rid of GPS issues while using Jikantaru's XE ROM and it worked.
Ended up using the Euro version as my main ROM until 7.2 of Cyanogen from Alquez came out.
Still have an issue with the wifi in that so I, at Alquez's suggestion, use the libril.so from that Euro stock rom in Cm7.2 and it works much better.
The Euro stock release was solid in all regards, strong wifi, GPS, phone signal, etc.
Just follow the instructions on how to flash a stock rom.
Thanks guys. Will let you know how it goes.
I just turned the phone on without a sim card and it all came back (nothing was 'unknown'. Does this mean that the sim has something to do with it!?
Hi guys,
I usually don't create topics because there is already a lot of solutions to my problems if I search well, but this time I'm really stuck since 10 days, I don't know if it's a hardware problem.
I bought my galaxy nexus GSM version in January, I leave in Frane, I had some randoms data drops (1 per day) but I just needed to toggle airplane mode to get it back.
I never unlocked or rooted my phone (since the problem)
Here is what's happening. My phone only get network when I'm home. I turned off the wifi on my nexus, still have network, unplug my internet box, still have network.
So I go for a walk to see if it's still work, I just need to go downstairs and my phone loose the network. Impossible to call or be called. Toggling airplane mode do nothing. I tried to put another sim card (in fact 3 differents sim card from different mobile provider), not working. When I go back home, reboot nexus, everything works fini. I'm trying everyday to understand why my phone only works at my home.
Baseband : I9250XXLA2
Android : 4.0.4 IMM76I
Kernel : 3.0.8 franco kernel Milestone 4
What i did :
Reboot phone and take off battery/sim when the network is lost.
Bought another sim card
Rooted my phone and instal rom (AOKP Build 39, APEX)
Flash kernel (Franco kernel milestone 4, Fugu mod)
Flash baseband (XXKL1)
Changed ril with getRIL
Factory reset, wipe cache/data, wipe dalvik cache
I swear my phone is not fallen on the floor and did nothing wrong to get this problem
My nexus is going for warranty on Wednesday. If you guys have any ideas, or anything I did not already tried, do not hesitate!
Thanks!
Hello,
I have different problem. My Gnex is suffering random signal drops when my phone is on 3g network. On 2g network everything is fine.
Like you, I tried a lot of thing. Root, flash different roms, kernels, radios. Download getril, matched radio etc. Also tried to unroot and flash 4.0.2 stock rom. Nothing changed. Today, I went to Samsung service a they flashed new Samsung kernel... still the same.
So please, someone help us about problems that we suffer.
Thanks.

hi all
i have a droid incredible 2, rooted with cm9, i am now in europe in vacation but after i rooted it it doesn't read gsm sim cards anymore!!
i tried the cm10 and still it doesn't even recognize it!
i tried to use several other cm9 roms (cm9 OFFICIAL GLOBAL, cm9 Unofficial but none of them detected the sim) . i tried a miui, incredible_2_HD, and god knows whatelse (...yes, spent lots of time here) , they did recognize the sim but just kept endlessly rebooting my inc2 after showing the home screen!!!
1) do those non-cm9 roms need aeroevans kernel and googleapps installed too?
the cm9s up are more stable, so i tried the build 4 for cm10 cause it mentioned it worked with GSM networks. no luck, i get data through wifi but it doesn't even see i have a sim card in there!!
oh, and if i recover the original verizon's OS it just keeps rebooting as soon as it hits the home screen...endlessly!!!!!
any idea why that happens!?
so...there is any way i can use a gsm simcard in any rom on my incredible 2?!!?!
thanks
I am curious too... I bought this phone to unlock and it doesn't recognize there is a sim card in the phone at all... It would see the reader isn't reading... I believe it's stock but I haven't even played with it. It needed a new usb port so I fixed it and got the unlock code from verizon. I have successfully unlocked two other phones so I'm not sure what could be the problem... Never had one not see the sim
Edit... Still doesnt see tge sim but successfully unlocked it

I picked up a Sprint prepaid HTC 816 recently and decided to flash this rom below
[ROM][UNOFFICIAL][CM12.1][5.1.1][VirginMobileUS][A5][single sim][1/1/2016 security]
That one
It installed great, had everything everything working after I added my Sprint APN settings. The phone still displayed it as Virgin Mobile and only 3g seemed to be working. But I was making and receiving calls, text messages and had mobile data.
Fast forward a couple of hours, I installed a custom theme from the Play store, rebooted and ever since then I lost the ability to pickup a network signal and access my APN settings.
If I re-seat the sim and toggle airplane mode it will pickup a network signal and I can regain apn setting access again but it drops within minutes.
Ive reflashed the rom, wiped everything reflashed again, same thing. Any ideas on what has happened?
Thanks and appreciate your time!

Are these the APN codes you used(poster corrected a mistake in green text)? Looks like there is a different APN for prepaid /postpaid.
http://androidforums.com/threads/working-sprint-prepaid-apn-settings.920752/
I indeed use the apn settings in the green from that post. They were working fine until I had a reboot. Then everything went to ****. It wont even let me access the apn settings and when I can its briefly and then I lose signal and apn access.

I had an issue with something on my Virgin mobile 816 a5_chl a while back and a member @wxppro was very knowledgeable about APN settings and their intricacies. He had a MVNO 816 at the time with an APN issue and I bet he could help you with this as that was my best suggestion for a fix and it didn't help you.
See if you can direct him here to this forum so that if he can help out the info is here to help others as well. Good luck.
Not sure how much I can help. APN is a tricky business. If your APN settings disappear after some time, it is generally because the cellular network the phone connects to does not match the APN's MCC/MNC numbers. Or it could be the phone is in 3G mode (CDMA EvDo mode).
You can try these things:
Switch network types, from LTE to 3G, wait a minute, and then back to LTE. APNs do not show up in 3G mode. They only show up in LTE (or global) mode.
When you have the APNs show up, check the parameters are correct, you can do a "Restore to default" and then add the new one following that post.
Hope this helps.
I'm having a similar issue as well (except on virgin mobile)
A month ago I flashed squid's version of CM 13 on my phone and everything was fine for a few days, until I completely lost LTE and access to APNs. I reverted to stock and still was unable to get LTE, although I could get a shaky 3g connection if I changed the network mode to CDMA only. I called virgin mobile and they walked me through the troubleshooting steps and eventually determined it was a network outage (even though two desires in my house belonging to other family members had LTE). I called again after they verified that the network was working again and they were still unable to fix the issue.
Recently, a friend upgraded from a desire to a different phone on a different network, and gave me his old phone. I plugged in my sim card and activated this new phone and I got LTE. Figuring everything was good, I decided to flash squid's ROM once again. The same issue happened, I got LTE for a day or two until it cut out service again. No access to APNs, not even any service in stock or on the official build of CM12 with the APN fix (I can't access APNs there either). I'm out of ideas and would appreciate if anyone had any input on my issues.

I have this same phone a5_chl Virgin Mobile. Did you factory reset your device before flashing back to your stock rom? The other thing is and this is just my opinion not a statement of fact or a knock on the wonderful Bigsupersquid but that 13 CM ROM is nowhere close to being stable enough for me to risk flashing it to my daily driver phone. Just read all the posts and his candid responses. You were basically a beta tester .
I'm not an expert in APN's but if you can't get that fixed your last resort might have to be wiping your system and then flashing or running the executable RUU (rom utility upgrade) file found for our device on HTC/downloads . This is a last resort option and wiping your system will remove your existing firmware so have the correct RUU for your phone downloaded to your computer before attempting a wipe. If it's an exe, which I believe the U.S. Virgin Mobile one is ,you will hook up your phone fully charged in fastboot mode then from your computer run the exe RUU like any other exe executable program and wait. It will reformat all partitions and reinstall pure stock ROM. Hope someone else had an easier fix for your data issues and good luck.
EDIT: you will need your stock recovery flashed back and a relocked bootloader before flashing the RUU but I've read that some have flashed their RUU over a custom recovery with a locked bootloader and it wrote over the custom recovery with the stock recovery. I have never personally tried this just the first way I mentioned and that worked for me.

I did try factory resetting and I am on stock after flashing the RUU. It makes no sense as the RUU should have reset everything. That perplexes me the most

OK then you did get back to stock not from a nandroid backup but from flashing or running exe stock RUU? If that's the case then it replaced everything that might have been changed and your issues shouldn't be related to any APN changes. You also removed and reinserted your sim card as I believe, correct?

i posted about my lte issues i had for nearly two weeks, running stock just to verify the data service problem wasn't my rom...
i had to install stock recovery, relock bootloader, download the ruu.exe from htc and extract the .img file in Wine, then rename it onto the sdcard and reboot into hboot so it'd flash. neither Wine nor virtualbox xp talk correctly to any of my phones over usb. and i wasn't about to native install Windoze.
factory reset stock didn't fix it, even trying activation, update profile, etc.
i learned i could get 3g data but switching to lte instead of cdma shut down data entirely.
virgin eventually directly escalated me to tier 2 tech support in my last call, they sent a couple service programming pushes to the phone that got my lte back online.
i tried the various service programming menu options repeatedly, with no results but the prl updated once; but the trigger to fix my lte seemed to come from upstream.
i tried various apns, in cm12, cm13, and stock lollipop. rebuilt init_a5.cpp with different mccmnc and adjusted apns. i really tried most tricks in the book plus a few more.
as far as alpha testing goes, at this point I'm just sharing something cool... i always enjoyed flashing latest greatest on my ov way before i was building.
not too many actual logs to really bug report for either rom.

Some of that was over my head but happily not all of it. Basically what your saying is the fix needs to come from the carrier and it's a reset issue on their end not a custom rom issue? By the way I'm a big fan of your work. Hell I might be on one of your older ROMs right now I've flashed so many I forget. Thanks for the education.

The first time it happened, I flashed back to stock using the RUU.exe. I tried again but the second time I took out the SIM card before running the program, I still can't get LTE.

It does sound a lot like a carrier/account issue as I managed to kill 2 different 816s. I don't think it's the SIM card itself because I put it into a 3rd phone and got LTE, although since it was someone else's phone, I didn' t bother activating it.
I guess you got lucky with support, I tried talking to them and they tried the same thing with me. Although all I got was excuses saying they're logging a ticket with their "network engineers" and to call back in a few days. This continued on for a few weeks until they determined I needed a new phone, which I was also bounced around for another few weeks (I still don't have it).
I'm just completely lost now. I'm almost certain it's my account and it needs to be reset, but I can't get a tech who can help me. How did you manage to get someone in tier 2?

This is starting to scare me as well because I'm thinking of going back to stock once Marshmallow gets pushed to our phone to get my beats drivers back and this is making me think twice. Sorry your having so much trouble.

seemed that way.
i took radio logs before and after it worked, and worked only on 3g, and it looked to me like the sim card responded differently to the ril after things were running right again.
mine might've been a special case, though, it came from ebay with no sim, and virgin had to go to a little effort to get it programmed when i installed the sim initially.
they also claimed for several days that the local Sprint tower was down for lte service.

tier 2 takes luck, time, many calls, and eventually you learn the answers to all the questions tier 1 outsourced from India asks so you can feed it to them so fast they want to shuffle you along. takes a couple of weeks to over a month to get to tier 2 and sometimes they have to be involved multiple times as well.
I've been dealing with virgin since 2009... replaced only two phones, eventually got the rest of the issues hammered out with persistence.
for a little while, twice, i had direct toll free numbers to American tier two even because my issues were so hard to solve. it didn't take too long for those numbers to be disconnected, though.
