[Q] Can you turn off LTE in any of the ICS ROMs?

Hey all,
I tried searching the forums first, and couldn't find a match to this question.
I was able to successfully install the initial skyrocket 4.0.3 leak, but I abandoned it because it didn't give me the option to disable LTE (under 2.6.35.11 it's Settings -> Wireless and Network -> Mobile Network Settings -> Network mode).
I don't have an LTE package, this isn't a reason I got the phone, and I've seen how much it can drain the battery even just having it on.
So my question stands: are there any ICS ROMs where this option is available? Is this something I'll have to wait for in a potential 4.0.4 release?

Try Embryo ROM.

My understanding is that we would need to wait for a Rogers rom. So far, all the leaks have been AT&T roms.
There is a way to switch networks on the ICS roms, but it's not particularly convenient. You pull out your SIM card, and do it through the RAT settings (*#2263#).

There is no actual way to disable the LTE radio, even on gingerbread. One of our members used radio monitoring hardware to check, and even with 2g only enabled, the LTE radio was still active.
With that being said, u can change your gsm frequencies using the rat unlocked *#2263#* method as already mentioned

Bah. I didn't realize it wasn't actually disabling the radio. I do appreciate the information though, so thanks

A Question about Unlocking and Rat Locked Radio

I have a Galaxy S II running the UCLE2 ICS Leak, I love the phone but there are many times I'm in a area with a real weak LTE Signal but a great HSPA Signal and times I'm in a 2G Only Area.
I know that the AT&T Modem is Locked so you can't switch off LTE or set it to 2G Only, If I got the Unlock code would that also remove the Rat lock? if not can you use a Rogers Radio on a AT&T Rom?
Thanks

No removing the sim lock will not help i believe the only radio that is unlocked is the rogers KJ7. Not sure what rom your using but some have a selection in the network screen i am using ChimeraVsSkyrocket_Beta2 and it has that option sorry i was trying to get you a screen shot but the usual buttons are not working

So is it safe to flash the rogers radio with me being the AT&T Radio?
If I flash the Rogers Radio with the AT&T APN's Should everything work as normal?
And If I decided to go back to UCLE2 Radio is it you like your basic flash with CWM or would I need to do the Samsung 1 Click to restore the phone to stock?
Thanks so much for your help

Rogers radio will work with att... though signal and speeds will be different. maybe better, maybe worse. its different for everyone.
and it will only work if the rom you are using has the option in it. such as a rogers rom or some other custom roms.
and flashing back to ucle is through cwm. exact same as when you flash the rogers radio...
i'd try the new rogers radio if i were you. it should be RAT unlocked. i get drastically better signal over every other radio (though i am a rogers user).
you may need to switch roms though. if thats the case i'd advise using the chimera rom. since its confirmed to have it. (not very many AT&T roms do.)

The latest rogers modem works with SKY ICS. I flashed it but the signal sucked so I went back to ULALC4(Best for me). Not sure if this is what your looking for but theres an options in your wireless network settings that allows you to use only your 2G networks. Actally has a sub title the suggests it saves battery. Might wanna check it out.

T-mobile 4g Radio

OKAY so I decided to update this thread:
There are two versions of the One X. One with aws bands and one without. I have a device without AWS (I am about 80 % sure). There are reports of people getting 4g on AWS with the Rogers Version as of now, and more testers need to check it out as it could still be possible on ATT.
This flash here theoretically could enable the One X radio to lach onto AWS (The radios here are for the One S Ville.)
http://ville.giev.de/?page_id=42
I have flashed all three, and although I did not get 4g, I got faster ping and a near immediate connection onto T-mobile. To all the people saying this will "brick" the phone, it does not and you have nothing to worry. But as always make sure to do a backup. The radio hacks for the Skyrocket/Note were also based on flashing the Galaxy S2 radio directly on top. This should work the same.

I'm interested in this as well. What does is involved and the risk? I don't have warranty on my phone, so I'm a little bit leery in being first.

if your rooted ull should be fine just make a back up of ur current set up. this is just a clockwork flash, it may not even flash, but if it does then there's a high chance of 4g.
i've done radio hacks before for the droid 3/skyrocket/note all from a similar concept. ex. flashing the t-mobile galaxy s2 radio on the note, to enable 4g.
if anyone could provide me with a better solution for an unlock i am sure i can get this to work. seems that the htc unlocker server is down right now
it's the same thing as flashing different radios via clockwork posted in the One X android dev forum

I'll give it a try, hopefully it won't mess anything up. So I just flash the radio in recovery. If no good, I just flash the correct radio again?
There is a one click no HTC Dev bootloader unlock in the Dev forum.

I flashed:
Radio from RUU_Ville_U_HTC_Europe_1.78.401.2 [Recommended] (update by rhcp)
0.16.31501S.17_2_10.23.31501S.10L
From your link. It flashed correctly. The phone on data and voice still works. I confirmed the version in Settings is not my original:
0.17.32.09.12_10.86.32.08L
I'm still on Edge, but I'm in a crappy cell area, so still not certain if radio or my area. I might give the:
Radio from Stock T-Mobile US (update by rhcp)
0.16.31501S.02_10.18.31501S.08L
Radio a try too.

good to hear no negative results got my phone unlocked so i will be testing tonight. also do u guys have the newer sims or older ones?

I have an older sim I believe. It is one that came from an activation kit I bought off ebay. I tried the T-Mobile radio and same results, still on Edge, but still could be my location.

What in gods name are you guys doing! ? Are you trying to brick your phones? It's already been confirmed that the hardware on this phone does not support the proper bands for T-Mobile 3g!

It's not just the SOC that determines hardware compatibility. There are various radio amplifiers and filters which are tuned to the specific frequencies that the phone is likely to encounter. If a phone is going to be sold in multiple markets, sometimes the hardware filters are set up for all frequencies and some are disabled via software, but often times this is not the case.
It's not impossible that a radio reflash can make it work, though highly improbable.

Interested in this. There might be better luck flashing the tmo radio since I don't think any European operators use AWS bands, correct me if I'm wrong.
Can anyone explain why flashing this radio from a different device won't brick our phones?

I have a tmobile one s, but i also have the one from att and i am so interested on using this phone over tmobile 4g let me know if i can of help. I am using my micro sim that came with the one s and i am getting edge (asume its the latest from tmobbile 4g mucro sim. I am on 1.85 rooted but i did not unlock. though i am sure we can flash through CWM. any ways i am sure there is a way out to get 3g or 4g on the one x on tmobile did not find the way yet.

flashed both of the t-mobile modems no luck for me either, although my ping is significantly higher and connects to t-mobile a LOT quicker.
does anyone know how to edit the LTE settings. it is odd but for most ATT LTE phones they have the 1700mhz frequency i think it would be a matter of just defaulting that....
the radios also show up in my baseband so i have successful flashes
EDIT: one more thing, before i was not able to use data at all considering i had the newer t-mobile sims but now data works but on edge speed.

it's just a file in your system. it could potentially brick your phone but you can always get into recovery and restore. which is why i stated you should create a back up of your device before trying it out.
however, i was fairly certain it wouldn't do that because the internals of the One S/One X are nearly identical, they both share the same processor and most likely similar (if not same, radios).
either way, the the radios work, getting me higher ping, and working data without having to switch out my sim for an older one, hope there is a way to activate the 1700 band !
http://www.gsmarena.com/htc_one_x_at&t-4614.php
EDIT 2: apparently there are two models of the ATT One X/XL one with the 1700 band and one without

Likely the software has been changed to support T-Mobile, but the hardware (filters, amplifiers, etc) are non-existent, so you'll never get actual 1700 MHz AWS support.
Of course, this is just a 50,000 foot view perspective without actually trying it myself.

you might be right about this one but there are certain One X/XL's that do have the 1700 band found out through some searching and trying to figure out the reason behind it.
If that's correct.... the people with the 1700 band would have 4g when they flash this radio! also use *#*#4636#*#* to change network type to lte/gsm
--- for other phones though like the Skyrocket/Note they were directly compatible with T-mobile radios.

Okay, I flashed the Tmo One S radio and did not receive a brick. What I did receive is a not-so-good connection that will switch between HSPA+ and 3G quite often.
I don't have a WIND sim to test with, but I tried running AT commands on my phone and they don't seem to be working. I tried doing a network scan with AT+COPS=? waited forever and had nothing displayed.
Strange...

Rebooted and ran the commands again. Still don't see any AWS carriers.

Don't you need a wind sim to connect im pretty sure the Canadian version will work on aws

Confirmed on my end that even with the T-Mobile radio, I'm not getting HSPA+. Even when I drove by the Moscone center where 1900Mhz was refarmed during Apple's WWDC (maybe it was just that day?). I was hoping this would be like the Note and Rocket where I can flash different radios.
Any other new phone capable of this? The S III? If not, I may have to either wait for 1900MHz refarm or switch to Straight Talk.

Picking up an att s3 today to test it out. Most likely there's two versions of one x one with aws and one without. I know mine doesn't though.

I'm not exactly sure of this one.
If someone is willing to let me cut up their WIND sim (or lend me their WIND microsim), I'll re-flash the tmo radio and meet you somewhere to test it (Toronto, please).
~dan
-----edit-----
Just popped in an old WIND sim that I used to test AWS connectivity at first. Saw WIND Away with the standard radio, and after flashing the Tmo radio I see WIND Away and AT&T (AT+COPS=? shows Rogers, ATT, Telus, Bell).
I live by the lake, that would explain why ATT shows up.

[Q] Disable 4G (LTE) and General Radio Help

Sorry if this has been posted somewhere else but I did a bunch of searching and couldn't find anything that explained what I'm looking for. Just got the Skyrocket and I'm trying to disable the LTE. 4G is awesome but I'd like to conserve my battery as much as possible and I don't need the super awesome speeds when the phone is just sitting my pocket while I'm at work. I've looked at a few different ROMs, both ICS and JB, and with the stock radio (UCLI3) I can't tick the check box for 'Use 2G Networks Only'. It checks then unchecks and then grays out. I tried a few different radios too, UCLL3, UCLK4, UXLF3, and a radio for Bell for the I757 that I suddenly can't find the info for. All of them work and give me 4G just none of them work with my ROMs to let me use just EDGE.
So far the ROMs I've tried is the new Dirty Unicorn JB ROM, AOKP ICS, and CM9.1 which I believe is also ICS. What am I missing? The last phone I used I didn't have to mess with any radios so this is all new to me. In short, what radio do I need to make this work with the ROMs I've already tried or can I get a recommendation on a ROM/Radio setup that accomplishes this? I'd prefer a ROM that is AOSP since I'm not really a fan of TouchWiz (It just doesn't feel right for some reason).

Did you try going in settings to mobile network click on mobile network mode and change the setting to gsm only? That should give you up to hspa and hspa+ for data speeds. As for using just EDGE I can't help you with that...sorry.

I believe the UXLF3 Radio is RAT Unlocked and that's the one I'm using now with Cyanogenmod 9.1 and I managed to get it to use 2G only. Not sure why it wasn't working with AOKP which is also ICS. I'm not sure if there are any RAT Unlocked radios for Jellybean yet but now that I've got it working I'm afraid to try any other ROMs lol
All this radio stuff is still making cross eyed though. I feel like someone needs to do a really good write up explaining it because it's not easy to wrap your head around if you've never had to mess with it.

[Q] Flashing T-Mobile radio onto at&t skyrocket

I have a rooted and unlocked at&t skyrocket on jellybean 4.1.2 with very slow speeds, so I tried flashing the radios UCMC1 and UXUMA7 through cwm and nothing has changed. After messing with the APN settings a little my data is no longer working. It shows the bars but I can't get a connection.
I flashed the radio UVLI1 in hopes that I would get lucky but that caused my bars to go away to be replaced by a slashed circle. I flashed back to UCMC1 which is showing the bars, but still no data connection. I have broken my back googling and searching forums on this matter but I can't seem to figure this out. Any help please?

http://forum.xda-developers.com/showthread.php?t=2349914
Don't double post

I think UCMC1 and UXUMA7 are ATT and Rogers radios respectively. UVLI1 is the T-Mobile SGS2 ICS radio, which may not work on your JellyBean rom.
Try UVMC6, which is the radio for T-Mobile's SGS2 Jelly Bean update. You can find it here:
http://forum.xda-developers.com/showthread.php?t=1895400
Results can never be guaranteed, but this is the radio I use, and it has worked fine on every single rom I've tried, Touchwiz or AOSP, even in areas w/o the 1900Mhz refarm.

Can I flash the radio change w/out having my phone rooted?

It depends on what you observe using either of these..
Try them one by another and see which one is better (UCMC1 vs UX radio) in signal and data speeds ... Personally I couldn't find any difference in my location ... Both gave me the exact same signal and data speeds (TM LTE).

The UX gave me faster data speeds. Call clarity is about the same. I see 4G more than with the UC radio... I was wondering about the T-Mobile radio
Sent from my SAMSUNG-SGH-I727 using xda app-developers app

T-Mobile radios would give you the ability to connect to T-Mobile 3G using AWS bands 1700/2100 Mhz Band4...And no LTE (or 4G) of course since the Hercules and Blaze (or the note one from TM) devices have no LTE radio chip...
If you live in an area in which T-Mobile deployed their new LTE(and most likely they already refarmed the PCS 1900 band), use UCMC1 or the UXMA7 radio,whichever you find better...Setting the apn to fast.t-mobile.com is essential for sure to get the service...
If you live in an area that T-Mobile is still at their 3G service (AWS bands for HSPA+) use the newest blaze JB radio...
Edit : when you say faster data speeds UX vs UC , any speed vs speed measurement you can share ? probably I didn't give each radio enough testing and jumped to conclude that they have same data speeds !
