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!

I too have the same problem.I tried flashing stock firmware via odin and even officially tried to upgrade to froyo but still the problem persists.

I'm currently using CM 6.1.2 on my Milestone.
If I switch to 2G mode in the mobile network settings, I have no connection.
If I use the Toggle 2G app, it doesn't seem to really do anything. If I set 2G to use one of the options that don't disconnect me (WCDMA, CDMA or GSM 2g/3g) it still shows 3G in the status bar so I'm not sure what the point is in using the Toggle 2G app.
Wondering the same thing myself...
Does anyone knows the answer?

I am not certain about this (i use rogers), but i believe that telus has no 2G (edge) network. They built a 3G only network just in time for the olympics to replace their cdma network:
So the toggler probably cant find a valid connection and retries 3G.
Manual mode cant find a network at all.
On rogers, i can fallback to 2g. This is normal according to what i think i know.

thanks for the info.
That's what I thought so have given up on the idea of getting 2g to work
I guess when it comes to 3g and saving battery life, juice defender will have to do as it can turn off data when the screen is off but still have the phone working.
Well, I think I made some progress with this.
On my phone, I was also loosing the connection when switching from 3G to 2G but it's working now. I can get calls, it's only the data aver 2G that doesn't work now.
I have the Cronos rom on my phone, I can tell you what I did if you're interested.
Yes please do.
If it works on cm6 then at least I can also save juice by not using juice defender... oh the irony... lol
edit: hey look at all them Canadian flags, eh?!

Took me a lot of time to find the right switches combination.
Anyway, I have Toggle 2G auto managing the 2G/3G and for the bottom 2 options:
2G network: WCDMA preferred (3G/2G)
3G network: GSM auto (PRL)(2G/3G)
If I check under Setting/About/Phone/Status, I see written mobile network type UMTS.
Hmm... I had those 2 settings reversed when using toggly2g
I will try that.
Right now, my mobile network type shows up as HSPA.
Your post prompted me to find the difference and came up with these 2 useful pages just before my head exploded.

Is this not the same then as just shutting off data?

Not sure but I don't think so. You can turn off the data but have the phone connected to the 3G network, right?
I think you could get data over 2G but it's just very slow, right?
With Telus I don't think they allow data over 2G.
zeppelinrox, I wonder why yours shows like this, what do you have active under those settings?
What ROMs are you guys using?

When I'm on 2G it shows as UMTS
With 3G (mobile data enabled) I see it alternating from 3G/UMTS to H/HSPA.
I'm on CM6.
My phone always shows HSPA except if I set it to use 2G then it shows GPRS - which is when I have no data and no phone signal.
I did use the Telus baseband file in AOR though... I wonder how it will behave if I use the Canada baseband....
Also, here's a neat trick....
dial *#*#4636#*#*
A Testing App will show up....
Select Phone Information and then goto the bottom.
You can set your preferred Network type.
Ok so that listbox shows all the different options.
The only options that will save are:
GSM only (2g - I get nothing - shows as GPRS)
WCDMA only (3g - shows as HSPA)
GSM auto (PRL) - (3g - shows as HSPA as well)
All the other options either are not selectable or just revert back to GSM auto (as is the case with WCDMA preferred)
I just did a few speed tests and I seem to get faster speeds with GSM auto than I do with WCDMA only
Gonna try that Canada baseband now....
Edit: Same thing. Except the speed test is slower for both WCDMA and GSM autio so best off using the Telus baseband.
The dial trick doesn't work. I dial the sequence as a phone number, right?
It disappears then nothing changes.
ah.. yeah sometimes it takes 2 or 3 tries...
do you use adw launcher?
If so, you can actually create a shortcut for it... I figured it out today.
1 Press and hold on homescreen and select Custom shortcut
2 Press "Pick your activity"
3 Select the second item on the list ie. Activities (with the ADW icon)
4 Wait for all stuff to load, scroll down to Settings, and press the arrow next to it to see the long list of activites that Settings.apk can do.
5 Scroll down near the end of the list, you will see Testing(.TestingSettings)
6. Select that and press OK on the next window.
I also made one for Battery History, which is actually part of the Testing app but is usually only accessible through Spare Parts.
I still can't get the trick to work... doesn't do anything on my phone
Right now I'm on the 2501 rom (latest 2.2.1 from Motorola) and I can say it's the best I've tested so far!
Outstanding battery life!
I found another way to run Testing App.
With Google gesture search you can set it to launch Settings actions
Let it scan and then write "testing" on the screen
Edit: oh crap I mistyped the code.
Its *#*#4636#*#*
I had 4536 before so I fixed it

Well, after doing some more tests and trying different apps (2G/3G switchers) I can say those apps work only if your cell phone company has both 2G/3G network.
In Montreal, only Rogers has both.
Easy to test (btw: I'm using the FroyoMOD rom): go in "Settings" -> "Wireless & Networks" -> "Mobile Network Settings" and check "Use only 2G networks".
See if your cell phone company is listed when you do a search under "Network Operators". If it's not, don't bother using a 2G/3G switcher.
When doing this, in Montreal I see only Rogers listed. If I uncheck "Use only 2G networks" I see all 3 of them: Bell, Telus and Rogers.
Hope this helps!
My carrier has bad 3G operation, whilst HSDPA works fine. The problem is that phone sometimes switches between 3G and H, and when it does switch to 3G, there is no internet until it swithes back to H or down to E. I'm almost sure that this is caused by carrier, and I can't fix it with firmware. So I would like my Tab to avoid 3G mode at all, while using H and E. Can I set it to do so?

Unfortunately, it's impossible, you can either choose "H" & "3G" with wcdma/umts or "G" & "E" with GSM in Mobile Networks. You can't choose to leave out 3G when it's doing H, cause both of them are under wcdma mode.
Of cause, if you leave your "Network mode" to auto, it will jump around gsm and wcdma when it see fit. By choosing it to run GSM mode only, will keep your network connect to "E"/"G(gprs)" ONLY; Or WCDMA for "H"/"3G" ONLY.

Hey Guys!
I'm from Argentina and I have bought (via Amazon) this amazing phone. It is the Developer Edition 32GB, XT1053. I think it runs the T-Mobile rom. I bought it because it is the global GSM version and its LTe bands works down here (same bands as US) well.
So far so good with this little and fast phone, but I was really surprised when i went on to check the preferred network types options, and found I only have 2 options: Automatic or 2G. There is no "3G/2G" option as I use to see in other phones. Normally you would expect 3 options here:
LTE (which includes 3G and 2G also), 3G (which includes 2G also) and just 2G.
Thing is, so far I don't mind this since Its cool to have it automatically, the phone will always try to find LTE and if not, 3G... and if not, 2G. The thing is, Argentina is currently setting up LTE over the country these days (yes, we suck), and in the future the operators 'might' charge an extra cost for using LTE instead of 3G, and that's what worries me... not having the option to limit the phone to 3G/2G was something I wasn't expecting and honestly I don't want to flash the phone to another rom, not at least in the near future.
Anyone knows if this "Automatic - 2G" setting is normal to see in this version ? Do you know if there's some kind of workaround to make it work under 3G/2G only in case I need to avoid LTE in the future for extra fees and so ?
Thanks for your help guys!
Edit: Forgot to mention, the phone came out with 4.4.3 but I upgraded it via OTA to 4.4.4 right away.
Yes the Automatic - 2G option is normal for the xt1053 retail stock. Android has hidden menu that gives more options tho.
Use this app to access hidden menu: https://play.google.com/store/apps/details?id=com.snclabs.radioswitcher&hl=am
Scroll down to where it says set preferred network type and change to whatever you want. gsm only being 2g, wcdma only being 3g, and so on
If the setting doesn't stick after reboot you can try toggling data off then on after changing the setting. try a few times it will stick after reboot.

Thanks man! That app will be really helpful to me if it happens that the operators start charging extra fee for LTE use in the near future.
Btw, I don't understand that much all that names. What would be the options for having 3G and 2G ? Should it be "WCDMA preferred" ? (I guess that takes away LTE) I will not use it under 3G only since I will be without signal if I happen to run into a 2G zone. (yes, we still have a lot of 2G zones in this country )
Thanks!!!!
I use rom Pure Nexus rom and have only 2g 3g and Lte option in seperately. Pls someone advise wherever or any rom have option for auto switch network like 3g priotiy then weak signal will switch to 2g
Tks so much

the phone will do this automatically in either setting, just leave it on lte and it will have the better tech whenever it finds it and if it looses it it will switch to the lower one within specified thresholds. i know it will switch to 3g from LTE at -120dbm but i dont know what the threshold is for 3g-2g
