3G not working. Please Help.

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.

So, other SIMs are working with different radio versions? I think that your phone is fine.

Might be a trouble from operator side. Check Telenor SIM on other phone.
If it will work - flash factory ship ROM on yor DHD and flash original radion version.
It's strange mystical part, but stock ROM resolves a lot of troubles

No success

This Is strange... Is your device made in china or taiwan?
Reason for asking this question is that, taiwanese made DHD normally generate certain problems out of the bloom that usually makes no sense.
From my understanding, When you flash a rom, you format the data partition and this partition holds every change you made to the os during the time of use. So there isnt any reason why a mode you left your phone in before flashing another rom should have such an effect.
Have you tried inserting another sim from the same mobile operator?
Edit:: And what rom is that? It looks nice. Can you give me a link to it?

It cant be a simlock. It takes more than airplane mode to throw a device in sim lock.
And if it was sim lock, it would only accept one particular sim card and not accept some simcards and reject others.
These made in taiwan Desire HDs develop problems that dont mount up to any proper explanation, as i already said.
Like mine, its taiwanese made and when i take out the simcard, it runs smoothly, but as soon as i insert a simcard, the device becomes laggy/slow. i have tried so many things but they all dont seem to work. This isnt the only problem, there are others.
This only leaves me with the conclusion that, the taiwan made DHDs are immetations/fake.

[Q] No HSPA+ after Kitkat update

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) ??

Here u find almost all modems

Same issue here.
Same issue here. After upgrading to Kitkat, never been able to connect again to HSPA+ signal. When I try network mode "GSM/WCDMA" I get EDGE signal then when I choose network mode to "WCDMA" only, I have a signal but no internet and the symbol "H+" or "H" doesn't appear on the top of the screen.

Can't unlock SIM with unoffical ROM !

I have a Tmobile UK phone running a Cyogen ROM. I want to move to different network (GifGaf), but upon inserting the SIM the phone requires unlocking. I've got the codes for unlocking, but they don't work. After a bit of search it appears that I can only unlock my S4 mini with the official ROM installed which I must admit surprised me.
Therefore does anyone know where I can find an official Tmobile ROM for a UK S4 mini ?

Hi !
You have all firmwares you want at "Sammobile" (internet site) ,it's official and you must be registered for to download ,it's free (with slow download)
It's a known problem...impossible to unlock sim with customs by "classical" way (and i don't know if it's possible by hack)
In theory,you can flash again a custom recovery and after a cystom rom without loose sim unlock...
Be careful !!!!! Don't loose the number of sim unlock !!! Because if you want to flash customised firmware (ste ,N5...) => there are chance that the phone will be relocked at your T-mobile !
I don't know exactly but it's a possibility because i have see that on a old S2 updated with officials => it loose sim unlock after .

Thanks for the info.
Do you know if its possible to re-install the official ROM using Cynogen recovery or do I need to replace that also?
Reason I ask is that I tried installing the official ROM last night in Cynogen recovery and it aborted almost immediately.
