Everything Seems OK-But NO SIGNAL- HELP !!

I now have the following :
Firmware : 1.5
Baseband : 62.50S.20.17U_2.22.19.26I
Knrel : 2.6.27-00392-g8312baf
[email protected] #72
Build : CRB17
After the first install, i did a wipe and then as fellows --
This is my present situation now--
I go to Mobile Networks (Data Roaming is ticked and Use only 2G networks is also ticked) , then i go to Network Operators... then i click on Search Networks.... here i sometimes get "Error while searching networks" and sometimes i get the name of my network along with the otehr networks but when i click on the network name..it says "Your sim card is not allowed to connect to this network"
I have ried it with LOOP MOBILE (earlier BPL MOBILE) and also with AIRTEL.
The sim cards work perfectly fine on other phones, but not on this.
Is it a hardware problem? if it were a hardware problem, then i would probably not get the list of network , right?
Any suggestions...HELP !!!

Same thing happened to me after I upgraded to the latest radio, I live in a att/verison only area so I am roaming. My g1 just shows an x like there is no signal while my dash is on EDGE and full bars. So if anybody can help out, more than one person needs this info.

a new thing i just realised in my phone.
when i stand very close to the a GSM tower...i get about 2-3 bars and as soon as i move away from the GSM tower... i dont get network.
i guess my problem is an hardware issue... ???
Or maybe not..!!!!

[Q] Network selection issues, not wifi related

Anyone on froyo have this problem?
This includes anyone using custom rom
The only way I can get it to switch back to 3G is if I use samserv debug to change my band to WCDMA only.
if i do the following I get this problem:
1) From WCDMA/GSM (auto) or WCDMA only -> Change to GSM only
2) I get GPRS signal -> then i get emergency call only due to bad 2g reception in my area
3) Change GSM only to either WCDMA only or Auto - it does not change back to 3G and stays as is in GPRS mode, and I lose connection. Won't turn back on to 3G again.
Never happened in 2.1. Only in 2.2.
The problem with staying on 1 band is:
My home has bad GSM signal, but 3G does not have a very wide coverage in my region. So in some areas, if there is no 3G signal I lose connection totally and people cannot get me. When I am at home I cannot be on GSM because I get no connection. Whereas 3G signal is not too bad where I live.
Anyone have any ideas how to solve this? Or is this a hardware issue? I'm not entirely sure if its hardware related because I can get the bands if I force it to via debug. But it won't auto switch nor will it switch inside the regular settings menu.
On all 2.1 versions I never had this issue.
On 2.2 stock DXJPA i started having this problem.
Now on darky 8.0 and this problem is still here.

HELP!

WCDMA signal horrible

I've flashed my phone countless of times now over the past months and one thing I was hoping for would be better signal strenght for WCDMA mode... I live in Switzerland and my provider is sunrise. Whenever I'm using WCDMA mode the signal is just horrible. Mostly 1 bar or sometimes dropping to zero. 3g and H works most of the time, but the signal is bothering me.. I've tried different modems etc.. but nothing seems to change.. Does anyone else have this problem?? what can I do about it? GSM has full bars most of the time and that's why it's so weird.
also worthy to note is that people hear an echo sometimes when they're talking to me both in GSM and WCDMA mode.

it would be great if someone knows how to solve this problem...

have you been on your providers website to check the coverage in your area ? they could be a fault on their part affecting your signal strength
Im on Vodafone UK and i have terrible 3g signal, I can only use 2g/GSM otherwise my phone doesnt recieve 1 bar of signal - bit of a bummer when you have a smart phone and unlimited internet
Finally, How was your signal before you flashed ? when the phone popped out of the box ? was it still poor then ?

[Q] Any way to force 3G instead of H or H+

Guys I have an odd problem.
Where I live, the signal on the HTC One switches erratically and constantly between H+, H and 3G. At every switch of course the data connection goes offline. It's driving me crazy.
Is there a way to force the phone to one of the three: 3G or H or H+?
Please see image 01.
I've tried going into *#*#4636#*#* but the choices baffle me (see image 02). I've tried a few of the available choices but it seems that 3G, H and H+ fall into the same category.
It's probably a dead end, I can't imagine what else to do ..... has anyone else had the same issue?

The 3G logo means it's on voice only, and H+/H means there's data incoming/outgoing. They're using the same radios and frequencies, it's more like an idle state when it shows 3G. 3G will still periodically go up to H+/H to check for any incoming data then goes back to sleep at 3G.

I have the same problem with my connexion. It is only stable when I have the "3G" symbol. I did not find a way to force "3G". It seems the switch to "H" is on demand...

It's normal behaviour, if you have a good H connection it will switch to this when there is data traffic but when there isn't it will switch between 3G and H

Weak (no bar) 3G signal after back from 2G

Anyone with Android 6.0 experience this issue?
So, when the phone enters an area with weak 3G signal, it will go to 2G (GPRS).
This is normal behavior.
Then, when the phone enters an area with strong 3G signal, it will go back to 3G.
This is also normal behavior.
Except, the restored 3G connection is weak. The icon shows with "no signal bar". It is connected to 3G though.
And it will stay like this until I recycle the connection by going to airplane mode and turn-off airplane mode.
My device is Nexus 6, international model. I installed Android 6.0 by flashing the image.
It is not rooted though and it doesn't have much apps.
And yes, I can reproduce this issue every time, as I know exactly the weak 3G area in our building.
Thanks.
