GSM 3G/2G signal dropping - Verizon Droid Incredible 2

Well i have a big problem, i'm using the DINC2 over a GSM network with the 900Mhz freq for 3G.
I had the 2.3.4 then i downgraded the rom to 2.3.3 using the method posted in the development section.
Then installed CM7 and everything was perfect until the moment i made a nandroid backup, after that the handset went crazy, first dropping the 3G until the point that it drops the signal completely not even gsm.
I have tried several radio version and the problem persists, i'am willing to go back to official 2.3.4 if the problem is solved but again since i'm not in the US i cannot upgrade the device via OTA.
I need help i cannot use it without 3G.
EDIT: I managed to get it to work stable at 2G, but whenever it makes the handover to 3G it drops the signal completely and return back to 2G, it works stable if i leave it in GSM only.

Can't Connect 3G

My Desire just can't connect to 3G. Also, if I go into settings, there used to be an option to force 2G, that bit isn't there, all I have is the option to use GSM or WCMDA or something.
Doing speed tests, it never gets quicker than 43kbps
Thinking back, when I rooted it, I did the new radio update and it network locked my phone. I then flashed back a radio that someone posted, but I guess it must be related to that.
How can I put the original radio back on to get 3G back?
If it matters, I'm on Orange in the UK.
Thanks.

How is your 3G connection since latest radio install?

This isn't related to any particular ROM as I have tasted this with various sense and none sense ROMS... Has anyone since using the latest radio had issues with connecting to 3G or having very strange fluctuations, where the signal might go dead completely then back up to full?
I seem to be experiencing this with 32.43.00.32U_5.09.00.20
nope seems fine with mine. OD rom in Australia

The mentioned Radio is really poor in 3G Network. Especially change between 3G and EDGE. When I disconnect from Wifi it too often doesnt connect to the GSM or 3G again - the bars are there, you can phone but cant use data connection.
I hope there'll be a updated radio soon!
Im not happy with 5.09.00.20.
Hi,
I'm also experiencing a poor 3G connection with this radio.
I'm not happy with that.
Vodafone Spain, also same while itinerance in Portugal, USA.
Best
this radio has been absolutely fine for me.
having poor reception at singapore here too...
should i downgrade the radio?
Working best for me. From Malaysia.
Not working at all well for me. All was working great until I flashed to this radio. I'm now experiencing complete signal drops at least once an hour, have to toggle airplane mode to re-enable.
I tried rolling back to each other radio bar the first 3 or 4 with the same result.
Could it be something else or am I missing something when rolling back the radio?
It works fine for me as long as I stay in Copenhagen, but I've experienced losing signal altogether when travelling, this didn't happen before, so I think it's because of the radio.
I have a weird issue where I never seem to be able to access the Internet in any way until the connection icon changes from "3G" to "H". Is this normal? I haven't noticed this on the stock radio but then I didn't keep it that long...
Still having this "issue". Anyone else?
New version is working really better here.
Where could one get that version? And is it supposed to work on any ROM without breaking it?
I have the 32.44.00.32U_5.09.05.30_2 radio and am on Telus.
I have the same issue as you. When the icon shows 3G my internet doesnt work at all but as soon as it changed to H (bang) full speed internet..
It did it for me on the 32.43 radio but not on stock. Anyone know what the stock Telus Radio is?
Guys you do know on telus we dont have a 3G network its strictly "H" that would be why your internet does not work. I would like to know how you managed to get stuck in 3G as i never have.
I have no idea - i just updated radio and rom to 2.2 Official (but rooted) - i entered the apn settings from the telus website.
When on internet things will be fine, internet loading (H in task bar) and then suddenly it will turn to the 3G icon and internet will freeze until the H icon comes back. Strange...
When i go into the settings and check my phone model it says its a HTC Desire A8181 - i checked the internet and this model is 3G Dual-Band 900/2100MHz.
Before i flashed a 2.2 rom my model showed as HTC Desire 8182, which is 850/1900 3G.
Could this be why its getting stuck on 3G instead of H?
My model also displays HTC Desire A8181 and I'm running a 2.2 ROM.
I don't remember what it said before on the Telus stock rom, but I could try flashing it back to see, since I have it in backup.
If you could try flashing it back that would be great - i think i have my Nandroid backup but its on my works computer...

[Q] Wifi performance after radio update?

I have been running the original sense ROM on my DHD downgraded from the 1.72 it came with to 1.32 to freeze bloatware and get rid of the annoying SMS notification bug. Was working great until I tried a new radio to see if I could improve my patchy Vodafone UK 3G sig.al at home. I tried the latest stable radio from Cingular and found 3G and GPS was good but wifi was suddenly terrible! Right next to router and only getting 'fair' signal. Thought I'd return to original 1.32 radio using the one in the radio thread but this has made no difference. Wifi signal is now poor upstairs with only my network visible whereas I was getting Excellent with multiple networks nearby showing. Is this a radio problem or settings? I never had best wifi performance ticked in settings. If it is a radio problem does anybody know how to return to the stock one that came with my DHD - UK unlocked used on Vodafone UK network. Any help appreciated greatfully!

Apparently these radios, unless WWE, are designed for a specific area. If you're not in the area you will notice some downgrading in WiFi functionality. Try a WWE radio and see how it goes.
shut down and restart your router and try again the wi-fi. that work for me the first time.
or you can boot into recovery and do a Factory re-set

Have tried most of the radios in the thread over in Desire HD development now with pretty similar results, even tried the UK specific test radio listed there. Currently on Radio_12.28e.60.140f_26.04.02.17_M2.
Have tried a reboot of router also, but that did little. I used to be able to see 4-5 nearby networks also but can only barely see one now.
Hi, would just like to report back to say I think I've fixed it. Is the wifi antenna connector on the battery cover like the network antenna is on the sim card cover?
Was at work and getting a really poor signal to the ADSL line here for external devices, whereas last week had nearly a full signal (2 rooms away). Just removed the sim and battery cover with the phone on so I could soft reset it in the process, cleaned the gold contacts and put back together and WiFi seems to be working great again.
Will report back later when I've had chance to test it at home but seems it was maybe a Darwin moment and I hadn't put the battery cover back on properly or the contacts were dirty?
That's good to know for future reference... cheers!!!

[Q] Sporadic GSM signal loss on Froyo [RESOLVED - SIM HW defect]

My phone loses signal often without any obvious reason - i.e. I've placed it on a table where the coverage is 100% and just leave it like this, but suddenly there's no signal at all. Usually in a while the connectivity is restored, but sometimes it just gets stuck without signal (installed "No signal alert" to monitor it).
I'm in Bulgaria, so there should be no problems with the UK release. I tried with 3.4.3-11 and 3.4.2-155, loosing signal on both. I just downgraded to 3.4.2-145 and the signal is stable for now...
For the record, I tested it with "clean" install - wiped, then flashed the SBF - no root, no clockwork recovery, no custom ROM, no apps...and the phone keeps loosing signal pretty often.
Anyone else noticed such behavior?
Hmm, I'm loosing signal with 3.4.2-145 as well...I'll try with different operator to see if there's difference. The other option is to downgrade to Eclair - which I guess is not an option anymore after flashing Froyo...
I'm currently using the 3.42.155 and haven't really experienced signal losses. Could it be that you must get your hardware checked? I hope you solve it soon! Goodluck!
3g and Voice calls are related, when you receive a voice call 3g is dropped, and when you hang up the phone its resumed, but if you have the wrong baseband it could happen the opposite, signal reception drops when 3g is transmiting/receiving.
This may be your case,
To the point Bad 3g speed / bad signal / drops in signal / drops in 3g, all is repaired just changing the baseband.

Sorry I left the thread without update - it turned out the SIM got defective, it just coincided with the Froyo upgrade and mislead this is the cause. After I downgraded to 2.1 it kept loosing coverage, than I moved the SIM to an old Sony Ericsson and I got "SIM Inactive" error...I don't get it why Android/Motorola can't distinguish such hardware defects...
not sure if it's your SIM, but when i was on 3.4.2-145, i also have this same problem. Had a friend with a Nokia but same operator, had 100% coverage and my phone with EMERGENCY CALL only. But it comes back in a while or so. Not sure if it's the ROM or not, but now with LiquidArc (with 3.4.3-11), signal seems to be very good, or at least on par with the dumb-phones

[Q] Voice and Data

Hey guys,
So I've noticed that I cannot do voice and data simultaneously (call someone and surf the web at the same time). I know its supposed to be possible under 3G and HSDPA for GSM networks. I am in a perfectly good HSDPA region (3G too for that matter, but my phone shows the H icon).
The only reason I can think that it is not working is because I am currently using the Vision_Radio_12.52. 60.25_26.08.04.30 (from *LEAK* Vision_Gingerbread_S_TMOUS_2.13) radio which is not the newest one.
So will upgrading my radio solve the problem (I can do voice and data fine individually.)? Or is it just not possible for some reason with this phone?
You can but only with 4g, the h on stock means 4 or 3g
No same for me and I am on a different radio the one ending .12,data turns off when talking,as to the reason why, I dont know, I just know it does not work.

Ok, but like I said, I am seeing an H indicating that I should be on a HSDPA network (there is a seperate 3G icon when I am in 3G).
Regardless of 3G or 4G, I thought GSM can support voice + data over both 3G and 4G.
Bombadier is using the latest radio and is having the same problem so I wonder what is the reason behind this...
Radio and ROM specs in my signature, I have no problems talking and surfing while in H or 3G.

Quick question do you have mobile network data always on?
Whatever the default is, I never manually turn it off, but I do use juice defender and allow it to turn off mobile data only when my screen is off.
Should of said on the phone running Unity, as I have it set from settings - wireless and network - mobile networks - not always on, will change it to always on and see if the connection stays on while talking.
Edit Just tested and the data connection stays on while I am on the phone,the OP should try mobile networks always on then.
My mobile network is already set to Always On.
When I get back home, I will update my ROM to the latest InserCoin v1.61 and the newest radio and report back. Hopefully, that will fix my problems.
Also, once I flash the newest radio, will I have to flash RIL too?
Just remember, newest radio doesn't always mean the best radio. I'm using an old one that after trying 5 different radios turned out to be the best.
Not sure about RIL's on sense though...
Seems to be all quiet about the need to match the rils,I used to, but had a few bad experiences matching the rils on the new unity releases 2.35+ so have stopped doing it,certainly with AOSP based roms it is not recommended to match,hope you get your problem sorted.
P.S. As the other chap said,the newest radio does not always mean the best radio,a bit of experimentation is required,also be sure to wipe the EFS data when changing radios.Link to a flashable zip can be found in the radio thread.
Updating to the newest ROM, kernel, and radio solved the problem. Thanks everyone for the help!
