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] Nexus One losing 2g/3g signal

I have a problem with mobile signal on my nexus one. Sometimes it shows no signal but it gets some (one or two bars out of four) if I try to make a call. I can actually make a call in third attempt. Sometimes it show four bars and my number is unavailable.
If I try to change settings to 'use 2G only', it loses signal completely (with 'x' above signal bars) and I have to reboot or turn on airplane mode to get signal back.
Model: Nexus One not rooted

Any ideas what may cause the problem???

I have the same problem, anyone knows how fix this signal lost???
Nexus One:
Android: 2.3.4

Same Problem
I changed my chip from GSM to 3G and having some problems with data connection. I know I have Internet when the bars and 3G icons turns green, but I don't have when they become gray... And I don't know why this happens... I installed the app Network Signal Info and when I saw the results I realized that it's a section saying... "Phone Type = GSM". Is this the problem? and how can I change it? Thanks in advice

Network Issue

I have a redmi 4x.
I am backed from cardinal aosp rom.
I am flashed miui 9 global stable rom by fastboot method.
Not working network search and 2g mode.
Please Help...
Pictures attached..

same problem here.. but little got a bit different
My XIAOMI REDMI 4X phone only can connect to 4G LTE and cannot find or receive 3G / 2G network signal.
Because of this problem i only can use one SIM at a time it coz when i use SIM1 for using mobile data, SIM2 will showing "No Network" this happen cause of SIM2 couldn't get 3G/2G network signal for its connection. Same issue if I switch SiM2 as my mobile data. SiM1 will be "No Network".
I really hope someone here could give me some solution to SOLVE this problem. also the SIM that i use to get mobile data it has problems that its cannot make out and receive any incoming call. Just regular Messaging are working.
another thing MMI short code also didn't work out it will pop-up with error msg like "cannot connect to server or no network connection" something like that.
This problem has haunted me more than a year and i still cannot get it fix. Need help because i am out of budget to buy new mobile phone .:crying::crying:
