Hello everybody,
I have a carrier unlocked Xperia Arc. I had flashed .58 firmware, which I had rooted with Zegrush method (bootloader is locked). It was working fine for a few days, then suddenly the 3G stopped working. I am still getting the EDGE (2G) data transfer.
Since my SIM when inserted into my friends Samsung i9003 was giving a good 3G connection and also my friends SIM when inserted into my Xperia Arc was unable to connect through 3G, I thought that the fault was in my Xperia Arc only.
I have
1) Checked APN settings, they are fine. Downloaded and installed them again to be doubly sure.
2) Did a soft reset
3) Did a hard reset
4) Used repair through PC companion
5) flashed .62 firmware with accompanying baseband
6) flashed .42 firmware with accompanying baseband
7) checked network mode. Its WCDMA(preferred)/GSM. On switching to WCDMA, the 3G connection works for a few minutes and then the whole connection drops.
8) I read in some discussion boards that a similar problem arises if the SIM card lock is used but I am not using it.
Is it a hardware defect? Should I unlock the bootloader and flash one of the custom ROMS?
Any other suggestions?
Please help.
Thanking in advance.
call your network provider and say your problem, if they cant solve your problem or says everything is ok then contact sony ericsson repair center.
Using official (as well as silviu's ROM) for Samsung Galaxy S4 mIni duos (i9192) on Jelly Bean, I could use HSPA+ network (when available). However my phone was rebooting everytime I activated my 3G/HSPA+ on one of the two sim cards... very annoying, my only solution was to deactivate 3G and work on Wi-Fi to avoid constant rebooting.
Therefore I tried kitkat version : it's even worse concerning rebooting plus I have no HSPA+ at all (same phone, same sim card, same network, same place) !! Modified ROM of Silviu corrected rebooting issue, but still no HSPA+ anymore !!
Can someone help ?

Hello, thank you for your quick reply !
I'm from BELGIUM and tried a lot of things without success... you are my last hope to solve.
I'm afraid I was too fast in saying rebooting issue was solved with your kitkat rom : it is not rebooting but I still loose network on both sim cards after activating 3G on one of them (and using it). Behaviour is slightly different as I don't get immediately pin code screen or rebooting, but I have to reboot and enter pin codes again to reactivate network.
You may be right about changing modem : what do you suggest ? I found one of your posts on this forum with a lot of modems : are they all usable with kitkat ?

Strange behavior u have there. unfortunately no, only 3 modems for now for KitKat . Russia, India, Chile
I think i only had one full network drop on both SIM since Kitkat and that was caused by Phone.apk crash . But my network came back online in 10 15 seconds or so.
On Jb, i had more Phone.apk crashes but those fully lock the phone and i had to force shutdown . ~1 / week or so
I have no clue what to advise u unfortunately. Sorry
Did u try without PIN-codes ? I don`t use them

Yes, I tried... unsuccessfull
Let me resume, I have now 1 more issue on Kitkat comparing to JB :
a) loosing network when both sim cards active AND 3g active on one of them (i.e. be asked for pin codes, unexpected rebooting, just nothing to see but get voicemail when calling my own numbers from external phone)
b) no HSPA+ (Kitkat only)
I tried to downgrade to JB in order to have at least HSPA+, but it gives an error ! ?
Please help how to proceed for downgrade to JB stock rom ?!
Thank you

Hello
I've noticed there is a new version for India... do you have only the MODEM: I9192DDUCNH1 for download and is this modem compatible if I install it together with PDA I9192XXUCNG2 (I don't want to reinstall everything, but only have bugs corrected in modem) ??

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.
problem solve without rooting and flashing

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.
Please help

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?
few ? the phone is unlocked my problem is why it wont allow data to work no calls text internet.etc it reads my sims shows my sprint number shows bars tried changing the apn settings to sprint but when saving it it disappears i thought wen the phone is unlocked it work with any carrier thanks for any info that yall can give me
And you have flashed the correct baseband and made any needed APN changes ?
Simply unlocking the device will not get you connected to another carrier without setting up the device properly after unlock...g
My friend brought an original refurbish Samsung N910v android version 5.01 which was working with GSM 2G if not 3G until when I tried to update to new version android v6.0.1. In the menu>setting>about when I checked first before anything it showed me N910 F v5.01 but in boot mode Odin it was N910v.The problem started when I just typed *#9090# the phone immediately started reboot loop. I have managed to unlock the boot loader and root the phone installed custom rom version 6.0.1 by Paul Pizz rom VRU2CPJ2.r-1 but still can not have 2G or 3G GSM network. Please help to revive the phone again whether it meant to go back to 5.0.1 that would work with gsm cause am full stack now.
Have you checked to ensure you have the APN information in place? I have a Galaxy Note 4 N910V now (just got it a few days ago) and when I put my T-Mobile SIM in it from the very first time I have to manually put in the APN data - on custom ROMs it's usually picked up and there automagically but not always so, my suggestion is that you check to make sure your APN information is currently there as it should be.
Settings - More - Cellular networks - Access Point Names - make sure the one you need to be using is selected and if it's not then you'll have to put that info in manually and save it.
As for the actual model number, take the battery out and see what the model number is on the sticker in the battery compartment area - if the sticker isn't there then it could be a device that someone has done some experimenting with because that info can be changed. The sticker should be there, of course, but sometimes people take 'em out when they're mucking around with stuff, who knows.
Initially the phone is from Verizon but was working on 2G ,3G GSM network with N910F firmware version 5.0.1.it was working on airtel network until when I wanted to update. May I have the Apn settings,please

The APN will be your network. Are trying to use Verizon? If so, you should have a spot to tic the VZWINTERNET. If not, then you have a sim card issue.
ziggy the how do i sort out the sim card issue ,Since phone says this sim card is not from verizon

Is the sim from verizon? If you have a good account go to a corporate store and have them give you a new one. It's free.
Also, what are your APN settings and I will compare to mine. Everything works on mine.
the fone I have came from china ,am in Africa and remember I told you it was working woth N910f firmware version 5.0.1.All am asking is there anyway I could make this fone work again on Gsm network, cause all it says after re flash is the card is not from verizon
I now rooted this n910v android version 5.1.1 still no network, am in Africa where there is 2G&3G GSM network, how would I make this fone to work again with the gsm network now that I rooted. On the network bar I get a circle with a cross ,how to make this work

- N910VVRU2CPJ2_FullFirmware_NoAboot<--- Full Framework with no aboot so you will not re-lock bootloader, but will unroot and restore back to 100% stock. once your on the full stock check if your connections are working fine, if they are then install custom rom, otherwise change the sim card
go in settings, connections and select network mode to global, should be fine
