I have a rooted stock g2x. I tried scanning the set cpu barcode on here and it downloaded. I opened rom manger and the phone restarted but I don't see the app. Did I do something wrong?
Also I'm trapped in my contract and have NO 3g/4g in my area. Is there a way I could unlock my phone and roam other networks? (I have my phone set to data roaming with zero success) Or is AT&T 3g in a diff freq band? Also are there any benefits to changing my baseband ?
Would I still be able to make wifi calls if I used CM7? Is CM7 more stable than stock froyo?
Thanks in advance
TMO 3g and "4g" are different frequencies than ATT and other carriers in the US, so there is no way to mod the phone to use them. I'm not an expert but messing with the baseband seems to be a recipe for disaster based on my browsing of this forum.
Also I recently went from stock to Eagles Blood 2.2 which is based on cyanogen. Wifi calling works fine. SMS works fine, however mms over wifi doesn't seem to work, its a known issue. Overall the rom is noticeably faster plus there are additional options and eye candy available.
Hey xda!
I'm getting a SGS3 soon, and I was wondering if getting the i9300T model (as i've only been able to find T models) is worth getting, especially if I'm considering installing a custom ROM (cyanogen) to then use it only for calling and texting via my OPTUS network (SIM), would I have to flash another modem on to it JUST to get the network to work (e.g. texts and calls), or would I only flash another modem on to improve the 3g internet speeds.
As i'm not looking to use 3g Internet on my i9300T with Optus SIM, would I be good to go without flashing any modem on?
I'm kinda new here, so please go easy on me if I've mistaken anything,
Any help or guidance would be appreciated

Hello everyone,
I would like to share big problem what I have and killing me.
Sometimes (1 time in a day or 1 time in 2 days), GSM signal is lost and I have to restart my nexus. What I have done so far,
* I checked my IMEI number and that's OK
* I checked my sim card againts to damages and scratches and that's OK. But these is gap between sim tray and card by ~1mm. The gap is only on long side of tray, short side is fully matched.
* I checked signal power and asked to carrier (TR AVEA) and that's OK.
* I installed hidden menus from Google Play then go to setting -> testing menu -> Phone Info
- preferred mode : GSM auto (PRL)
- If I select "select radia band" from pull-down menu, only one possibilities "USA Band". Even If select this, GSM and data signal loss.
- I tried another carrier sim card (Vodafone TR) and applied same settings above (USA Band), and failed again.
- I understand that "USA Band" is not suitable for us
My device is D821(E) and use 4.4.3 full stock firmware. No root, locked.
Can anyone help me? Thank.
After I updated to 4.4.3 (via purity ROM and Flashing the new Radio/Baseband) I noticed my data connection was constantly droppping in and out
So today I decided to flash the old radio from KRT16M (4.4.2) to see if it made a difference and it seems to have so far. I haven't had any loss of connection in the 2hrs since flashing, whereas on the new radio it was constantly dropping in and out. I will test for longer but i think the new radio in 4.4.3 may not be optimised for some networks (i'm on Optus in Australia)

2 months ago, someone from Turkey who use same carrier (TR AVEA) has noticed signal loss problem with 4.4.2
I remember that he has mentioned neither stock and customs has same problems. I think this is completely baseband problem.

I had same problem. Devs seem to think radios are the same for both phones. If they are why are there different models for usa and Europe? If you put a usa radio in uk phone it will work poorly as it has SOME bands and vice versa i found one marked d21 radio and back to normal. You are treated as a moron for thinking that the radios differ. Look at Wikipedia

Can you please share the name of baseband that you found?
And I checked the wikipedia and could not find any useful things as you said.
This is a photograph of the baseband I put in and another of the different frequencys the two phones use. Using D20 in uk drastically affects h+ as you will see by the difference

On lte , which includes h+on most, you can see the d20 radio is usless in the UK i was getting h at best and 3g most. Now im back to h+all the time. The experts say that there is no difference so take your pick.

Same baseband that I use with 4.4.3 OTA.
I always use 3G "Preferred Network" option.
Same problem here with the new 4.4.3 radio. Incredibly weak LTE signal (fine if I select 3G in Mobile Networks) and sometimes no signal at all. I may try flashing the older radio this evening.
I realised it was happening more often when my gps was locked.. As soon as i switched off gps my signal restored..
Running rooted 4.4.3 stock rom

I'm still having some issues with the older radio, not as many as with the new, so there may be something inherent in the 4.4.3 update as well, this is annoying as my phone was running perfect on 4.4.2, may have to restore my backup
Really nice phone and cool design.
But weird problems without solution

Guessing from the last line, you had updated to 4.4.3 through OTA? You could try to reflash the radio img but that would require you to has custom recovery.

That's because flashing different modem images (D280/D281) does not change your available phone bands. It is a hardware limitation, nothing to do with with firmware.
That was not on my phone. I put it on. As you can see in the pic above there is a world of difference between the two models. Depending on where you are if you get a d20 radio in a d21 your going to get no data like i did
# 47386
As far as I know, it depends on your network capabilities. I have a D281 running the latest D280 radio, everything works as fine. Faster LTE even.
am not sure what is wrong too but am facing this issue quite a lot as well. But it is not restricted to Nexus 5 only. I have another phone Samsung Galaxy Grand 2 and face the same issue.
Am not sure what to do on this, however, after some search I found a site where the author claims it gets fixed after uninstalling updates of the following apps:
Google Launcher
Google Search
Google Maps
Google Hangouts
Google Newstand
One or more amongst the apps might be causing some issues. See if it fixes your problems. I will be trying it too but will uninstall all updates from one of the above applications at a time to see which app is the real culprit. Please share with all of us in case you get to know before me or have another solution for us to try.
PS: Hit 'Thank You;' if this helps.
Hello guys,
I have a you yureka plus phone which I bought a week ago. I'm facing network problems with it since the time II switched it on. I am not able to get network coverage and therefore very less Internet speed in my home whereas my older phone gets amazing coverage and very high internet speed.
I have contacted the sim card operator and they weren't able to help.
I tried almost all possible ways to get rid of the problem.
I tried the *#*#4636#*#* thing.
I tried changing different apns.
Rooted my phone and tried different custom ROMs and kernals.
So far global ROM miui v8 is the best one as it gives network bars but the internet speed is stilp very low compared to the other phone.
I flashed a different modem file found here in xda but that also didn't work.
I'm out of ideas and I'd really appreciate any help.
Sim cards- jio and tata DoCoMo
Current ROM - global miui v8 based on android 5.1.1
Kernal - velocity v10.3
Thank you.
Hi !
This seems to be a device specific issue , maybe your network doesn`t match the device basebands , try changing them from settings/prefered network type and also get in tuch with your provider about this
Cheers !
i tried all the options in the preferred network type with no success. my provider said there's something wrong with phone's software and he couldn't help with that

Are you sure that the phone supports your carriers bands ? You may find that you are only able to get 3g or only have one or two of the bands that your carrier uses
Regards
Sawdoctor
I'm sure it supports 4g, because I get good 4g speed in my workplace. I'm having this problem only in certain areas like my home and college. How do i check the exact bandwidth capabilities of my phone?
Hello everyone,
so basically I need some help (obviously ) and my problem is that I can only get an E (Edge) mobile data connection, and I know for sure that my Simcard provider does support (European) 3G and a download speed of up to 4MB/s. I Tried a lot of stuff that I could find here on the xda-developers forums like dialing *#*#4696#*#* -> Phone Information then changing WCDMA preferred to GSM only and then back to WCDMA preferred and then going on options and selecting Europe from the "Select radio band" option. I've upgraded my radio from 1.20.50.05.16_10.31.50.08 to 1.35a.32.45.27_10.144.32.34aL with no success. I have tried flashing different ROMs for hboot2.16 starting from Android 4.2.2 up to 7.1.2, Sense based ROMs and AOSP ROMs, also with no success.
I've been trying different stuff, looking on other websites, even in different languages for a way to fix this with no success.
I'm starting to give up hope as I don't feel like getting POed because of this problem (although it was a great amusement to my BF to see how I act when I'm raging :good: xD )
Right now I went back to my normal ROM that I've used for the past couple of months which is Lineage 14.1 (I've clean flashed the newest release of it).
I really hope someone could help me because it's starting to go on my nerves ^-^
Thanks in advance!
EDIT:
I also wanted to say that I have an HTC One S (European S4 model) and my carrier is VodafoneDE and my Simcard is an "Edeka Mobil" card.
I've seen that about 100 people have seen my thread, a bit of help would be nice >.<
