[Q] No 3G on HTC Desire Z after perma-rooting and flashing World ROM

So I followed this guide (http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_G2) to root, S-OFF, etc. my HTC Desire Z which is on Bell's network with a data plan and everything, and everything was going pretty well. Then I downloaded this ROM (http://forum.xda-developers.com/showthread.php?t=822908) to de-brand my phone and it worked as well and everything is fine, except for one thing. The mobile network isn't working. My Wi-fi and normal cellular network that handles phone calls and SMS works, but I can't access the internet when there is no Wi-fi. Normally, when I would connect to the network, an icon would appear in the status bar showing when it was sending out and receiving information and what kind of connection it was (3g, etc.). Now, it doesn't appear when I turn on the Mobile network and I can't connect to the internet without Wi-fi. If anyone could help me fix this, I'd really appreciate it. Thanks.

Is it enabled in the settings and did you choose the right network type to use?
I recommend setting it to automatic.

Yes, and yes. The network is set to bell and the network selection is set to automatic.

Disabling 3G on a TF101G to save battery

G'day all...
I have a TF101G and I have noticed that the mobile broadband seens to be consistently at the top of the battery usage list even when I have mobile data disabled and (get this) even when I have the SIM card removed.
My TF101G spends most of its life within WiFi range and I only need the 3G when it's out of the house.
Does anyone have any idea how to disable the mobile broadband transmission? Maybe I'm mistaken, but it seems dumb that it's still using battery to check in even when I tell it not to use the 3G.
Thanks,
Alex.

How have you disabled it?
I've seen many widgets/apps that say they're capable of disabling APN connections but the only thing they do is modify the APN connection name, so the 3G is still active but it never connects due to APN's changed name. The problem is that since 3G is not disabled at all, it might still use battery.
If you disabled from System > Wireless and Network > Mobile Network > Use packed data then 3G is turned off for sure. Also any system app that could manage that should be able to enable/disable that option.

Thanks for the reply.
I did actually try changing the APN as well as removing the SIM card. I still see continuous battery usage for Mobile standby at the top of my usage graphs in Aplications > Battery use.
I don't actually have the "Use packed data" option under System > Wireless and Network > Mobile Network - I only have Data enabled, Data roaming, Access Point Names, Use only 2G networks and Network operators.
I can always to to flight mode for no connectivity, but I can't for the life of me figure out how I can make the TF101G WiFi-only. Surely there must be some way of doing it. Maybe the forthcoming ICS update will fix it - we live in hope.

Sorry, I was refering to "Data enabled". If "Data enabled" is toggled, 3g is enabled despite the APN name's. Maybe you could try to disable "Data enabled" and see if it doesn't consume more battery.

First thing I tried!
No joy there.

Problem solved.
See post by Notdawa in http://www.transformerforums.com/fo...p/16657-no-firmware-update-me.html#post149760
It's simply a matter of putting it in flight mode and then manually enabling WiFi. It works a treat!

I have now TW 9.2.2.4 FW and still if i do flightmode and then wifi on, i see cell standy as the biggest power consumer . to me it seems somehow the modem hardware is not properly switched off. anyone knows what modem chipset it is? or what could be the reason why this behavior?

If i do reboot with 3G modem off (so flightmode but with WiFi on), i get 'cell standby' as big power consumer after few hours. But reboot with 3G on (but no mobile data enabled) and also WiFi connected, then goingto flightmode + WiFi does not show 'cell standby' in battery chart . I had many problems and reboots with first ICS {9.2.2.3}, hopefully now i can get long and controlled battery life and no empty battery beeps in middle of night.

[Q] Disable Roaming "R" icon in status bar.

I am using an MVNO (Mobile Virtual Network Operator), so I have always had to activate "Data Roaming" in order to be able to establish a connection over the mobile data network.
Usually in my S3 which i was using before, I could see a sign next to the reception gauge which indicated me which mobile data standard my device was using at the moment (H+/E/G), even when I was roaming at these times.
Nowadays on my new Nexus 5 with stock Android 4.4 I am justing being shown the "R" sign next to the gauge, without any indicator for the standard it is using at the moment (LTE/H+/E/G).
Is there a way to disable the roaming indicator ? can anyone tell me or create a xposed module for the same if possible ?
thanks in advance. it is such a small issue but its annoying since i dont get full connection always and want to check whether i am getting 2g or 3g

Are u using Lycamobile?

Which country & network are you in?
My operator is a MVNO in the UK, but don't get the Roaming flag.
That said, when I was living in India if I travelled to a different state it would behave as you're saying - so wonder if it's more related to that than the fact it's an MVNO?

Yes am using Lycamobile and I live in Virginia, USA

Hi,
I have the same problem in Spain, also using a VMNO and on stock ROM I also get the R.
When I was using customer made roms (Cyanogenmod or AOSP based) this did not happen as in the settings menu there was an option of setting National Roaming.
I am using another different device than yours (Xperia V), but it is a common problem. If anyone knows a solution, perhaps with an Xposed Module, or whatever it would be very helpful
Thanks

Same problem, I miss the data indicator while roaming
This app helped to solve my problem. It's a network monitor but it also indicates on which data network you're on.
It's called "2G 3G 4G LTE Network Monitor" available in Play Store

I have a similar problem. Not on an MVNO, but I'm using an unlimited Telmex plan in Mexico, which give lets me use my phone and data normally when roaming in Canada and US, so i really don't care to know that on roaming, but i would like to know what sort of data connection i have, if any.

Mobile Connection

Anyone got any idea why i keep loosing mobile connection on my Shield tablet...
Sim card works just fine in any other device. Only tried phones though...
Do I need to do something special with the sim? any special app I need?

Do you need to set your APN up correctly for your network provider?
I know I had to do that for a MVNO I use here in Australia recently on my N5.

I found the problem (in my case) I had to reduce the preferred data protocol to 3g instead of LTE. Everytime my tablet got LTE connection it lost it's connection... Airplane modus on and off, and then reconnect... 5 min later.. bang... After I tuned it down to 3G this stopped...

mobile data stop working

Hi, my mate 9 mobile data stopped working today for no reason, only thing I did was connect the phone to the hotel wifi last night, not sure why is doing this. I tested the sim card on another phone and mobile data works fine so is not a service provider issue, has anyone experienced same behavior before? I already restart the phone and verify mobile settings but issue persist and have no data traffic unless I connect to wifi

Have you checked Settings -> More that data is turned on for mobile? Also check your APNs. Settings -> More -> Mobile Network -> Access point names.

yes all settings checked, I even disable restarted and enable them again

Are you on T-Mobile? If so it's an APN bug.. You have to create a new APN with the same settings and use that. The default one causes mobile data to keep being lost...

Thanks, this fixed it for me.

Was driving me nuts, took some trial and error. FYI i think some of the newer roms no longer have this issue, although because of the stupid Huawei blocking updates by IMEI you might need to install via FirmwareFinder.

Great thanks!! But I keep mine stock.

lost data
hi, Thanks' for your help, but in my case are not working.
I'm in France with Free Mobile, Since yesterday I lost data after being connected to a wifi.
I checked the settings and are fine
Mobile data: on
4g: on
Apn: erase the olds and make the 2 new following instruction on their site
mobile operator: auto
Any other solution ? or maybe is the phone operator?

I got the solution calling my mobile operator. They blocked for some unknown reason my data.
Thanks again
