Is there a way to turn off LTE CM10? - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Yeah that's right turn it off! Seems they just added a tower in my area but I get crappy signal in my house and on HSDPA+ I get full bars. I thought this phone automatically connects to the "preferred network" but LTE in my house sucks and it keeps connecting to it.

I tried that on multiple radios and can't get it to stick. I also tried disabling it with the optional LTE toggle but even with it off the damn phone keeps connecting to LTE, gives me 1 bar and about a half meg down. I get full bars and almost 10 meg down with H+. Its not just the cm10 ROM because I went completely stock with your very helpful stickies and it does the exact same thing.

Setting, wireless networks, more, and scan network manually. Set AT&T and than you can change network modes. Rogers or bell radios only. I prefer bell 757 radio. My phone is not unlocked and I'm on aokp.

That worked for me great. I followed your directions even used the i757 modem and it worked like a charm.
Edit: This also works on att uclf6 and ucli3 radios.

Toggle to cdma prl in York LTE settings and reboot. If I have LTE set on I get 1x all the time. Not sure if its the real problem or fix but seems to work for me. I'm also in a 3g area.

Same issue here.
This morning I wake up, and my thunderbolt is stock on 1x. If I switch to 4G, it will do 4g, but back to CDMA only, and stuck on 1x. I have 4G at home, but leave it on 3G because I normally am at work with no 4G coverage.
I flashed the stock mr 2 rom just to confirm and used the official radio just to be safe. No change.
Googled around a bit and here is a fix that worked for me...
Dialer -> ##778# ->Call -> Edit -> 000000 -> modem settings ->Rev A
Switch to enable from eHRPD and then hit back once. Menu->Commit.
Solved for me, but I don't know if it has adverse effects...

This makes your phone use the "old" version of EvDO. Basically what all 3g phones that don't have 4g radios use. If your area doesn't have 4g, doing this change shouldn't effect you at all and might get you 3g if you are stuck in 1x.

1X here all morning too. I'm in San Francisco.
On the plus side, my DL/UL speeds suck, but ping is 9 ms, so Mobile Hotspotting is still relatively fast.

Dont think you can use data while on a call when using EVDO, like you could on LTE.

You can in 3G with the Thunderbolt. I did it yesterday. I work in 4G but live in 3G, but this feature is what finally made me pick the TB over the Charge.
I started this morning with the 3G/4G toggle on 3G only, to save battery, and around lunch I switched 4G back on and it has been there since... I haven't had issues with 1X. Must be a regional thing.

Yeah this is a possible problem. The back has connectors for the antenna, and not having it properly secured could cause connectivity issues. Also a bad SIM card is something to check as well.
Try the OTA MR2 radio. It's working great for me. The newly leaked GB radio from chingy gave me some odd wifi issues.
On a side note, if you work in a place with stainless steel walls, you won't get 4G

Galaxy S2 Skyrocket i727R crappy connection on mobilicity

hello
I set up my unlocked i727r to work with mobilicity, however, it has very crappy reception. I tried the t989 KID modem, the vk1, the telus kj3, and the blaze modems. They all give me weak signal (anywhere between 0-2 bars with mobilicity), whereas my galaxy nexus has 3 bars. It tends to lose connection when I go inside a supermarket, and sometimes disconnects from the network and doesnt want to reconnect. I have the gingerbread, and I want to keep it. So, is anyone using this phone with mobilicity and getting a good signal strength? Do you mind sharing with me what you did?
thanks
Bars aren't really a good indication of signal.

yea what i meant to say is that its very unstable, it would take a long time to dial a number, it has crappy reception, etc. Right now my phone is connected to the mobilicity network, but under mobile network state in status, it says disconnected. What could be the cause of that?

I'm more or less in the same boat... in particular upload rate is horrible ~40kbps.
OP: any progress in your experience with mobilicity and in your search of a suitable modem?
It's the network not the phone. I was with them & got the same results with a Lumia 710 & the 727r. I tried all the different modems & the best is the Blaze 4G IMO.
Did you guys also have to change your kernels to get it to work?
I have tried the usual 4 radios combined with SKYICS and also with the stock OS (latest Rogers version) without much success.
I get some signal but as soon as I try to call the phone would hang on me (it would dial out incidentally).
Thanks a lot
Nope didn't have to do anything other then flash the recovery, to allow me to flash the radios from zip files. The Rom and kernel were stock GB or ICS. I did go into *#2263# and set WCDMA option from all to 1700, & the mobile network option from automatic to manual selecting Mobilicity or its network ID #.
Actually a couple of weeks ago I flashed the t989 juggernaut rom, with the faux kernel and vkl1 radio and its somewhat better.

LTE not working for me. (90% SOLVED)

Update: 4/13
I was just able to figure it out and for the most part. The basic problem is that my network mode was stuck on GSM/WCDMA. Here is the solution:
1. go to settings/more.../mobile networks/network operators.
2. Once you click network operators, it should start searching automatically. If nothing comes up, then hit "search networks". FYI, sometimes, it decides to act wonky, so you'll have to exit out and come back in to get it to work. Eventually, it'll show you carriers in the area. Being an AT&T customer in Philadelphia. I saw three results. The first two were AT&T. The last one was T-Mobile. I don't think there is a difference in the AT&T options, but I just clicked the first one.
3. Once that's finished. Go back to the "mobile networks" menu and click on "network mode" and change your preferred network mode to LTE/GSM/CDMA.
4. The last step is change your APN. In the "mobile networks" menu, click on Access Point Names. Click on ATT LTE pta. Scroll to the bottom and click on APN Type. Change that to default,admin,fota,mms,supl,hip. Then hit okay. Hit File and Save. Then just select the circle next to ATT LTE pta. To be honest, just selecting ATT LTE PTA might be all that's necessary. You might not have to edit it.
Now, here's the catch. All of this stuff resets (with the exception of the edited APN) when you restart your phone. But it does work everytime.[/COLOR]
So, I just got the skyrocket (AT&T in Philadelphia) and have the 03-24 nightly on it. But for some reason, I can't get LTE to turn on. I've played with the different APN's. I've flashed the at&t radio on Chopstick's webpage, but no dice. I'm only getting H+.
I even called AT&T to make sure my data plan was LTE provisioned.
The only thing I can think of is that the ROM currently cannot change preferred network mode and mine is stuck on GSM/WCDMA preferred?
Please help.

How old is your SIM card?
When I got my Skyrocket, all network modes except LTE worked.
It ended up being an older version of a sim card that didn't support LTE.
Swapped out for a new one...no issues since.

I doubt that's the problem. I actually flashed back to Stock this morning and LTE worked great. I had speeds around 35mbps. However when I restored the backup of the CM10.1 rom, same issue. Only gettings H+ and speeds around 2mpbs.
THIS IS SO FRUSTRATING!!!! I don't get it. Am I really the only person with CM10.1 not getting LTE? It doesn't make any sense.

Would you kindly answer these questions so that I may ascertain whatever is it I'm doing wrong?
1. Are you using an AT&T Skyrocket? or is one from Rogers/others?
2. Are you using the official CM10.1? Which build?
3. What your baseband version?
4. What APN are you using?
5. In the mobile network settings/preferred network mode dialog in settings, what option is checked?
The only thing I can think of is that the preferred network mode for me is stuck on GSM/WCDMA preferred?
