[Q] Loss of 3G/3G+ - HTC One V

Hi xda community,
Here is the status of my phone :
HTC One V (GSM)
Bootloader unlocked and phone rooted.
Rom custom installed "Primou OMEGA".
Rom tested : MIUI, SlimBean, Shpongle.
Since several month now, my HTC has a loss of network when it is in "WCDMA prefered" mode. It arrive to connect to the network just after a reboot, but 2/3min later, it fails. Sometimes it can reconnect but it immediately fail when I try to use internet.
Here are the things I have tried to solve the problem :
Change the Rom : KO
Change the APNs : KO
Use the SIM in another phone : OK
Use a new SIM : KO
Change Operator : KO
Change Radio mode to CDMA/GSM auto : KO
Change Radio mode to GSM auto (PRL) : KO
Change Radio mode to GSM // Force to 2G : OK
Force my network to 2G is the only solution which allow me to have a stable connection to the network, to call someone without losing the call, and to have a little access to internet (really slow...)
After several months of research, I don't really know what to do. THe last thing I've not tried yet, is to update the Radio firmware but I've read that there are a lot of things to check before, and not all devices can do this upgrade. Am i right ?
Have you some ideas that I can try ??
Thx a lot.

Rooted Desire - Now no data connection

Just rooted my Desire using instructions from Modaco, but have the following issue :
I have no data connection. No matter what I try it always tells me 'unable to connect, you need a network connection in order to..... etc. Wifi is off at present (not one around at work) and all the settings are to Vodafone as they should be. Can make/receive calls without issue. It's a fully unlocked phone so no idea why it's suddenly not able to connect data wise. This is the case whether I try to setup Exchange, browse the web or open Facebook etc.
Any ideas please anyone? I've checked all settings, rebooted etc but to no avail.
Someone, somewhere said that in some cases (don't remember which) APNs presets are missing after rooting. Check your APN setting.
1. Make sure your APN settings are 100 correct.
2. Go to Menu--Settings-->Wireless and networks-->Mobile Networks-->Network Mode--Switch to GPRS and then Back to Auto
Worked for me.

Mo
GOod call, it was the APN settings. Added one as below and all connected straight away :
Name : Vodafone
APN : Internet
Username : web
Password : web
Cheers guys

Are you using a Branded or UnBranded Desire??
see this thread for more info

But at a guess you might need a GoldCard and then Flash it with a new ROM/Radio settings

[Q] Network not allowed issue

Hi,
Since a couple of days my Desire won't register on the GSM network. The sim is working fine if I put it in another phone, so that's not an issue.
The message I get when trying to manually choose my network is "Your simcard does not allow a connection to this network"?!
After some browsing on the web it seems that this happens sometimes but I cannot find a way to get it resolved. One of the tricks should be to manually toggle the network mode to GSM only or WCDMA only. The strange thing is that when I try that the phone instantly swithes back to GSM/WCDMA auto. To manually change network mode is not possible. Is this an indicator that something is wrong?
I have tried to re-flash the rom, installing the latest radio, toggeling flight mode on/off, etc.
What else can I do get it resolved?
Currently running my rooted Desire with:
LeeDroid 3.0.7
Radio 5.17.05.23
Appreciate the support!
Thx!
Anders
I think you should try the offical RUU .. than you can make out if it is a hardware problem or software.. make sure to prepare all thing while your phone is in working state, before flashing offical RUU make sure u have usb debbuging enabled, adb driver working. and a goldcard..

[Q] 3G advanced configuration (help me please)

Hello there, this is my problem...
I flashed my phone and now I can't make 3G work. I have tried all this:
- call to my phone company and enter the exact parameters in configuration (user, password, server, etc)
- flash with another custom ROM
- flash with the original stock of my country (Chile) (via Odin, from Doky73 firmwares)
- backup from another GT-S5360L and restore in my phone
- enter into the servicemode *#*#197328640#*#*
Nothing of this have worked.
PLEASE HELP ME!
¿DO YOU KNOW A 3G ADVANCED CONFIGURATION MENU?
¿IS POSSIBLE THAT 3G IS GONE FOREVER?
HMM...
Did you try changing ur network mode to WCDMA? If its on auto mode then change it.. if still u dont get 3g or the H sign near ur network then its the fault of ur service provider

yes i tried changing to only WCDMA and I lost the signal.
I put the my SIM in another SGY and I changed to only WCDMA configuration and 3G is totally ok... =/
Maybe your current location doesn't have strong enough signal for your SIM card, try changing location
Sent from my GT-S5360 using XDA
It seems to be a really weird problem.. try asking your service provider for 3g setting FOR galaxy y. If it still doesnt work then ur 3G receptor is not working.
try turning on the packet data, and switch to WCDMA only.
if it does not work turn off packet data, then goto flight mode switch to GSM only and back to WCDMA and turn on packet data again. this also happens on my phone sometimes.

Network Signal Dropping every time after update to 6.0M (Poland)

When i bought D855p it came with 4.4, then i updated to 5.1, all official. After this i installed Cyanogenmod 12.1 and everything were fine. But when i installed 6.0(poland) my network signal keeps droping the intire day, it changes to UMTS and HSPA. I cant use my phone as a phone. The only way to solve this is, every time that i turn off the cel or put in airplane mode, is enter in MOBILE NETWORKS > NETWORK OPERATORS > SEARCH NETWORKS and choose GSM. (but i need to do this EEEEEVERY TIME that my cel turns off/airplane mode).
6.0 is the only ROM that i can choose GSM and the signal keep ~stable~. At least i can use my phone as a phone !
I did a backup of my IMEI before installing cm12 as well.
Things that i already tried :
-Flash ALL modem (ALL) , including 21C.
-intall cm13 and after cm12. Using TWRP 2.8 and 3.0.
-stock 4.4 , 5.0 , 5.1 and again 6.0. Using LGFlashTools
-MANY factory resets and wipes !
anybody can help me ? :good:

Try this. However in your case download the Polad specific .kdz files

Doesn't work , sadly :crying:
i also tried to put in Network mode : GSM/WCDMA ( worked ) but when i choose GSM/WCDMA/LTE auto , signal drops every time. It is a solution to do this, but i cant use my LTE, and it sucks ...
Disable VOLTE n go to ur models service menu (check google) for me it was
*#546368#*851# (my model = d851)
*#546368#*XXX# (ur model=D8XX) verizon sprint numbers are differently
go to field test >network mode>set GSM permanently (try different gsm 850,990,etc)
Back > RAT selection > select GSM
U cant have network problems now cuz ur permanently set to gsm dont use 3g or 4g use wifi
hit like it helps

I'm sad to hear that. Try also flashing modem 21C. There are also other guides for restoring your signal around the forum, different things seem to work for different people.
