After doing a manual root, the Thunderbolt connects to LTE fine but when there is no LTE, the 3G won't connect and the phone doesn't receive data.
Advice?
Try checking to make sure you are not in LTE only mode. Dial *#*#4636#*#*, select phone information, scroll down and go down and make sure you are on the CDMA + LTE/EvDo auto option and not LTE mode.
If that doesn't work, try downloading "reset connections" from the android market and running that app when you enter a 3g area out of 4g range. It may be a handoff issue from 4g to 3g towers.
##778# hit dial, edit mode, password is 000000, modem settings, Rev. A, change to enabled, instead of eHRPD, hit menu, commit changes.
try 3G again.
I assume like me, you are in a section where Verizon's Hybrid Network isn't working, and so you must tell your phone to revert back to their regular 3G network.
We have 4G in Pittsburgh, but there's a spot in Squirrel Hill that I go through on the bus in the morning where I drop to 1x, and I'm fairly certain that there is 3G there. However, there are other areas I've definitely seen 3G. So, it seems a little mixed. We're definitely early adopters of this new network
The fix
Phone ##778, edit mode, 000000, modem parms, REV-A change from ePHRD to enabled, menu, commit, reboot, problem fixed.
seems to have worked for me. I was having a problem with syncing too, hopefully this fixes that as well. Thank you!

Not to familiar with TB verizon, but friend bought his TB and I saw there was 4GLTE on it, and now nothing, no icon not in wireless networks, nada!
What is this "fix" for?
Dial *#*#4636#*#* go into phone information scroll down and choose wcdma only and your done default is GSM/WCDMA auto (PRL)

please excuse my ignorance, but what would be the purpose of this?
so that it dosent jump around from 3g 2g if its auto and your not using data it automatically defaults to 2g i think to save battery then switches to 3g oir hsdpa 3.5g or what att calls 4g on demand this keeps it locked on wcdma or 4g to my knowledge

seems like it reverts back to auto after a reboot
This makes the phone work on Verizon, right?

See that's what I thought too. ATT = GSM, Verizon/Sprint = CDMA.

Mine goes back to auto as soon as I back out of the menu. Am I doing something wrong by using the back button?
wouldn't this, by locking it, render the phone useless when traveling out of area that support that network?

Mine does the same thing. did you figure out how to do it? I have been trying but I couldn't do it
I found this here in the forum someone posted and it worked for me thanks for him.

Here's an alternate method I puzzled out (and then afterward discovered it was already posted in thread 751237. It's a bit faster and has the advantage of surviving flight mode; still gets reset upon restart.
Dial *#*#2263#*#* (mnemonic: *#*#BAND#*#*).
This brings up the Band selection menu which you can also access from the above method by dialing *#*#197328640#*#* then going into DEBUG SCREEN > PHONE CONTROL > NETWORK CONTROL.
Select [3] GSM BAND
Select [1] GSM ALL
Select "Select GSM All Bands"
Menu key > END
To switch back, go to *#*#2263#*#* and select [1] AUTOMATIC > Select GSM &WCDMA All Bands > Menu key > END.
Something else I'm trying out is switching the acquisition order so when it is in "dual" mode, it'll try GSM first. Even so, it will still switch to 3g if there's enough signal. Seems to help keep it on 2G though, when it would otherwise cling to a faint 3g signal with 0-1 bars.
To do that, go into the NETWORK CONTROL menu (see above) then
Select [4] AQUISITION ORDER (yes they misspelled it)
Select [2] GSM->UMTS
Select "Select ACQ_ORDER_GSM_FIRST" (at least they abbreviated it correctly)
Menu key > END
This option does not get reset upon phone restart.

I did this and now my sms or text messaging don't work help
I had this happen too, but I didn't use the above method. Don't know what happened, but when I checked message settings, I had no number under "Message Center" did a quick google search and found an ATT number "+13123149810"...now it works again.
Did u call the number
Never mind i fixed it.but now in my network type it says umts is that faster then hsdpa and are there any other number sequences i can use to tweak my phone
I'm getting RAT restricted, which I got on my Vibrant but never my Captivate...
How can I change to show the different bands?

wcdma and cdma have nothing to do with each other. wcdma is also known as umts, the base part of 3g (and 4g when hspa+). hspa is a protocol that runs on top of this cell technology providing higher data speeds. gprs (known as edge, and some times called gsm) is 2g. you can turn one or another off so the phone does not seek and connect to both services, which could save battery life. even though ive yet to see my phone find less than 3g/4g in houston, i still dont turn it off, just in case.

Thanks, John Madden.
Hi all,
I'm new to the Nexus S 4G root scene. I just flashed Miui yesterday, and I am getting no 3G. I couldn't find anyone else that was having this issue.
Everything else works, and I get 1x data, but not 3G. It's not the location because stock gets me full 3G service in the same location.
I flashed this kernel: http://www.peteralfonso.com/2011/08/download-nexus-s-263514-kernel.html?spref=tw
but it didn't fix anything.
Thanks for your help
Edit: After going out with my phone, I realized I do in fact have 3G reception, but it's very poor and constantly switches between 3G and 1x. I normally have very good reception with stock Android in my area. It doesn't stay connected to 3G for more than a few seconds at a time and switches back and forth between 3G and 1x
Have you set up the phone to use 3G at all?
Go to Settings, and find Mobile Network settings, and there should be one box that says something like 2g only.
You probably know what to do from there on.

Under "Mobile Network Settings" there is no option for that. Only "Data Enabled" which is turned to "on"

Maybe I'm just being dumb, but it's not there.
Settings > System > Mobile Network Settings
there are 4 choices:
Data Enabled (on), Always receive MMS (on), Data roaming (off), and System Select (automatic)

Any way to disable (release) HSDPA/HSUPA like on Samsung ROMs via secret codes? Using 3G instead of HSDPA saves a hell of a lot of battery!
Even going down to 2G (GSM) suffices for exchange push sync or any mails for that matter.
Settings -> wireless and networks -> mobile networks -> network mode -> GSM only.
This way it will enable just 2g, as 4g is just a push up of 3g.
In short you can not just get 3g.
Either 2g or 4g.
What you get is
3G+HSDPA
OR
3G+(HSPA+)
The phone should automatically switch to 3G when idle to save power ... Mine does pretty quickly

mine doesnt switch automatically.. it does ONE TIME. but after reboot, it's just constant H. ( yes I do have separate H and 3g icons in my framework)

thanks all for replying!
i don't have the 4G model, the fastest network we have is 3G/HSDPA 21.6mbps
actually let me test how the phone battery holds up with "H" before i try switching to "2G"...
thanks again!
How to Fix AT&T Data Throttle Your 4G - Your Data Usage is Among The Top 5% Of Users
There is a nice little APN fix. Just change the APN to Phone and force your phone to use HSPA in your phone's settings. I have instructions with a screenshot...
http://www.traemcneely.com/2011/12/...rottle-4g-data-anti-throttling-trick-for-att/
How do you perform the first step on the skyrocket?
1. Go to Settings > Wireless and Network > Mobile Networks > Click Network Mode and force your phone to use GSM/HSPA (Auto mode).
I don't see "network mode".
Click Access Point Name..
I am now getting 512k vs 150k.

Found another trick.
I named the access point the same ATT pta, then I put Phone under the APN setting.
Put your phone into GSM/HSPA (auto mode) let it connect to the network,
then go back and put it as HSPA only.....I'm getting 1-2g+ bypassing the throttle using HSPA+ works like a charm.
Att Throttle Samsung Skyrocket
i did all when i click on Mobile networks i see access point names and network operators and use packet data. When i click on network operators is says Default setup doesnt allow me to do anything. Please help
Same here. Don't see 'network.mode' selection. Please help. Does it have to be rooted?

I am still not sure where/how to pick "GSM/HSPA (Auto mode)" on stock rom. Thats not an option.
What I have are:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this
(Cut n paste from another thread, dont know if these are applicable to Skyrocket/LTE)

Thanks for the pointer to the thread but my whole point is that I dont see those options and for some reason my network mode changes dont stick.
So if I disable packet network, switch the APN, change the network mode and then enable the network again, I see that it has gone back to GSM?WCDMA/LTE auto mode again.
So for some reason my network mode changes dont stick. Also, I am on stock rom, could that be the reason!

Custom ROMS give you the options you are looking for.
I am confused ! If the stock radio is *locked* to use LTE if available, why are some people reporting to lock onto HSPA+ network with stock ROM. Are they exploiting some bug?
I have tried various things but I cant switch my radio to anything except GSM/WCDMA/LTE auto mode. It seems to come back to that mode.
Do I need a reboot after changing the mode.
I am using *#*4636#*#* to switch the mode.
Switching APN 's worked like a charm ;o)
