3G connectivity problem after flashing radio 1.27.35.28 and ROM 5.2.1620

The device has been successfully HARDSPL-ed and flashed new radio and rom.
Everything works except the 3G connectivity. When i choose manually GSM/EDGE band the data connection works without a problem. If Auto mode or UMTS band is enabled the device connects to the 3G network but can not establish data connection. It tries several times to bring up the data connection but it fails and after several attempts it loses network registration leaving me wit icon that shows ! sign on top . The same thing happens with all operators here ( T-Mobile Montenegro, Telenor and MTEL Serbia )
Can anybody give me a clue what is wrong.

hi dcetkovic.. your problem is same with mine.. until now no one can solve this problem.. until i gave up unsubcribe my internet broadband 3g.. is useless without 3g

Also haPpens to me with the radio of origin. Anybody knows some solution for this problem?

Problem 3g frequent disconnectios
I had the same problem with the version 1.27. The solution was to change the radio to version 1.58.21.23. The radio, sometimes, is not compatible with the operator. Test it and good luck!

i have changed both OS and Radio ROM to factory versions and still have the problem. It looks like a hardware fault to me.

Hello,
I think you must test with others roms radio. Visit this link: http://forum.xda-developers.com/showthread.php?t=461359&highlight=radio
And good luck!

hi there, is there a program that could set manually the GSM/EDGE band? my current radio is 1.27, it seems that it doest want to choose the HSDPA only. There's HSDPA signal on my location, i have an HTC Advantage and it shows that its connected thru (H) however on my shift. it only shows (E) Edge.

N1 on Three (3) UK?

I've just moved to 3 in the UK (from vodafone) and I can't get a data connection - I get the error "Data connection lost" reported on several threads here, however my old vodafone SIM (which runs out on Tuesday) runs perfectly fine on 3G
on 3 the phone test (#*#*4636*#*#) shows HSDPA connection and the ping test FAILS (with no response)
on Vodafone I'm also on HSDPA - but the ping test succeeds
I'm on
stock Froyo FrF91 -
rooted and unlocked
32.36.00.28U_4.06.00.12.7 baseband
and 2.6.32.9-27227 kernel
So
Anyone have a clue what the issue might be?
If I can't get this fixed I'll have to move (AGAIN!) , off Three - and onto somewhere else. I'm sure there are other 3 users with N1's!

More bizarre
OK - this gets more bizarre - can anyone explain this?
Take my 3 SIM to 3 Shop - plug it into a 3 branded HTC wildfire - and it works just fine. Use their 3 SIM from the HTC wildfire on my machine - and it work great. Plug my sim back into my N1n- it works just fine now. #*#*4636*#*# actually resolves my pings and get great transfer speed
All smiles
Drive home - check again - no name resolution occuring - no data download. still on HDSPA
:-(
WFT is going on here!!

Hello,
I'm on Three with a N1 and unlocked custom Froyo Rom. Works fine for me. Question, are you getting 2g signal, can you make calls etc, is it only 3g you are having problems with?
Are you sure there is Three 3g signal in your area?
Settings>Wireless and Networks>Network Operators
Can you see it there?
Have you tried resetting your APN settings to default?
Settings>Wireless and Networks>Access Point Names>
Menu>Reset to Default
Let us know how you get on.
Cheers.

Have you tried "WCDMA Only" instead of "WCDMA Preferred"? Works better on 3 for me anyhow in Ireland.

Well on the stock froyo rom it doesn't differentiate between 3G and H,but I always get 3G displayed - with 4 bars. Can make calls - no problem
The diagnostics always shows HSDPCA (or whatever!)
however it won't ping or resolve from my house
I drive into town (1 mile) - and it works
I guess its a reception issue??
Phone physically gets hot with the 3 SIM in - at my house - and battery life is appalling (3 hours to flat) - so I guess its trying really hard to connect.
I defaulted the APN again and selected EURO band only - and still no luck. No data connection from my house.
3 network coverage map says I have good coverage - and (as I said) 4 bars in signal strength.
Odd

Remind me - I know I've seen that option somewhere - but I can't find it at the moment
Thx

Set WCDMA Only the same menu you chose Euro Band from. It's a dropdown box.
It does sound like it could be a reception problem all right. There's also a new radio available which might provide stronger signals. Worth trying that too IMHO http://forum.xda-developers.com/showthread.php?t=723839

If u have 2g to make calls and Wifi for Data, then you might have to settle for that I guess, if your phone works 3g in one area and not another, I would say reception issue, do any of your mates have a Three phone they can test at your house?

Here's another tip, try the following...
Menu > Settings > Wireless & networks > Network operators
Select "Data roaming"
Choose "Select automatically" instead of 3
See how that goes.
PS I'm now using the new radio 5.08 I linked to above. Looks like I'm getting a stronger signal.

[Q] Bionic on GSM in India - Tata Docmo

Hi All,
I am starting a new thread for India specific networks on the Bionic.
I am new to this so please don't mind if i write anything stupid which i may haven't understood yet.
I got my Droid Bionic running on Stock ICS from States to India and inserted a couple of GSM sims which worked fine for a while without any tweaks. I used my device for one whole day(made calls didn't test data) and when in the morning i woke up there was no network. At that time in *#*#info#*#* it was showing as detecting network but as soon as the location updated, GSM would show out of service.
What i have done so far:
1. I flashed Eclipse ICS v 1.2 ROM and got network though very weak but couldn't make no calls.
2. I got ICARUS HD - 1.6.1 and applied the tweaks as mentioned in phone and got network stength increased but still no calls but a strange thing happened when i tweaked with build prop editor running ICARUS HD, when i changed to WCDMA Preferred and turned radio off and on it registered on the network gave full strength and GSM: showed in service as well, though this was only for 10-15 seconds and i couldn't test call.
3. Now I'm running CM 10 - released on Jan 18th and to my amaze I can use 2G Data though GSM state is Emergency Calls Only.
Following might be helpful to understand:
Current Network: TATA DOCOMO
Signal Strength: -99 dBm 5 asu
Neighboring CID: Unknown
Cellinfo: Blank
Roaming: Not Roaming
GSM Service: Emergency Calls Only
GPRS Service: Connected
Network type: EDGE(Also shows EDGE2 at times)
Message Waiting: False
Call redirect: false
Call Status: Idle
Preferred network type:
WCDMA preferred
I have changed to gsm only, gsm auto and all others applicable to no help.
I am trying to run my phone in India on network: Tata Docomo which probably operates on 1800 or it could be 1900 on 3G.
One thing which i am sure of now is that this phone certainly has all GSM capabilities and its some tweak which is required which i cant figure out. I have personally seen my phone making calls and now its running data as well.
Please help me on this!
Seems like settings changed with build prop to run on T-Mobile or AT&T dont seem to work for networks in India. Tmobile operates on 1900 and Tata Docomo on 1800
One thing which wont let me sleep is that why did it run perfectly at first and why did it fail if i did nothing to it. Can the network block the IMEI or something of that sort happened. It's been two sleepless nights for me now, now praying to the Radio God!! LOL!

Did you manage to get it to work? You might be right in thinking that it might be related to IMEI. Did you try and find out if the IMEI is considered valid by your operator since this is not a true worldphone its IMEI might not be in their database?

Didn't work. I had to give up on it. There was actually no way in which i could get it checked with the network.
I sold it off on Craigslist last July!
I now have bought another one to test. Waiting to get back to India to test it again.

Not all bionic works with gsm, only wcdma. It's HW A after 36/11 and HW B

It's quite interesting that it did work perfectly initially and then with CM10, the data worked. Did CM10 rom include its own radio as well?
I found something interesting in this thread (not related to Bionic):
http://forum.xda-developers.com/showthread.php?t=945312
Good luck with your new Bionic! Does it work okay with GSM carriers in the US?

I finally got to try it and unfortunately it didn't work for me. Mine is HW A '12 Bionic and I am on ICS. If I go outside my house and search for networks, I get to see only one network(not mine). I see extremely weak signal in the phone info screen and also it shows gsm out of service. I tried 3 sims from different operators. Inside my house, nothing ever shows up. In other phones, I get to see many operators. Seems like it's definitely a signal strength issue if the gsm 900/1800mhz and wcdma 2100mhz bands are not locked. I'm not sure at this point what is the real cause. I even tried flashing just the radios from GB versions as complete downgrading is supposed to brick the device. Needless to say it didn't help. I'm still investigating and experimenting.

Hi,
I have now tried everything possible with the Bionic to run it on GSM network in India but it has failed to respond. I tried both hardware versions and can confirm that it is not registered as a world phone like most of new Verizon devices.
The worst thing which still bothers me is how and why did it work once(Yes, I made and receive calls on Docomo network in India). It will still show network strength , detect network but not register. I cant find no answers to it and have given up on this. The model is now obsolete and is clearly not a world phone in my dictionary but I won't deny it having GSM capability having seen it work personally. I have finally dumped the other bionic as well.
Good luck with your experimentation though!

When I put the SIM i my HTC it is not detecting 3G Network.If I choose GSM/WCDMA it is selecting the 2G Network and for WCDMA Only option
it is not showing any network.
Please note I am having the HTC mobile fro HTC Hongkong and now using the same in India.
Operator: Vodafone
Activity Performed:
Restart the phone and put off the battery multiple time
Factory Reset
Use another 3G SIM which is also workng in my old phone
Toggling between flight mode and WCDMA.
Results:
Just received the 3G network twice and it was sustained for 20 minutes and so.
Please note I am having good 3G Coverage in my locality and with my old phoe it always come full signal.

It happens some time
I have to disable / enable 3G to make it works.

[Q] Unable to connect to Vodafone 3G (C5302)

Hi
I am in Kolkata India and recently switched from a 2G to a 3G plan with Vodafone Kolkata. Ever since then, my problem is that I am unable to connect to 3G using WCDMA. Neither voice nor data works. If I revert to GSM only, then voice and 2G works fine. Wifi has been fine and my saviour at home.
Phone details: Sony Xperia SP C5302 running Android 4.3 build 12.1.A.1.205.
I have confirmed with network service that it is not a SIM card issue, by carrying out the foll. tests already
1- Signal strength in the area of use : At the time when I am unable to connect to 3G, my colleague sitting in the next desk and using a Motorola phone is consistently able to connect to the same 3G network from his phone. So the network strength must be fine.
2- SIM damaged or dirty - I have obtained a new SIM card as replacement, after this problem started, from my service provider yesterday. But the problem is not resolved.
3- Manual network search and connection - I have tried this many times, using WCDMA only or WCDMA(Preferred) options. In either case, only on rare occasions, the phone was able to connect to a network. However, 3G data connection (H+ icon) did not show and then the phone disconnects from network. On most occasions, when I manually attempt to connect to the 3G network, I get the message "Could not register to the selected network. Make sure SIM is inserted."
3- Trying different SIM/Handset - I have tried out both options of switching SIM and handset.
- My SIM on Motorola handset - connects to H+
- Another SIM on my Sony - momentarily connects, then disconnects and then does not connect to network.
Please let me know if anyone has faced similar issues and found any resolution. Thank you in advance.

I think that there's an option to use 2G instead of 3G in the settings menu, have you checked to see if that is enabled?

That is the WCDMA option I've mentioned about, there was no other setting for this.
Anyways, it turned out to be a hardware problem. Got the "mother-board" replaced for free as it was under warranty & now working fine!
