no more 4g - T-Mobile, Samsung Galaxy SIII

I rooted my tmobile S3 today and it worked fine. Later I installed a cyanogen nightly sang noticed it was only getting 3g, so I did a restore to the stock rooted firmware through ROM manger. With that I got just bars, no indication of 4g or 3g. The phone wouldnt go to the internet, it said no connection available. I had to restore back to cyangen to get the phone just to work... but regardless of which settings I chose the phone is stuck in 3g. What is the fix? I'm going crazy here

Did you check your imei? Did you back it up?

No clue what you are talking about... so I guess no, lol

I don't know much more than you sorry. I know imei can get corrupted when flashing and it causes problems like that.

3G on cm is the same as 4G on tmo stock rom.
Try checking your apn settings on the stock rom since I think your imei is fine, without it you wouldn't have gotten 3G at all, even on cm.

Wait, are you just looking at the icon without it doing anything. Many aftermarket ROMs will show 3G when the phone is doing nothing. It will show 4G or H when you make it work.

T-Mobile 3G and "4G" are basically the same technology.

Did you fix permissions clear both caches?

It is not an LOL deal, if you have no clue that means you didn't bother reading anything about flashing a rom IMEI is mentioned all over, IMO you deserve no help what so ever since you think LOL is a proper response to not reading how to do the job the right way, enjoy your slow data speeds maybe if you learn to read it will work again

Slow Data on CM9/10

I've been looking for the answer to this question, but I can't seem to find it.
Does anyone know the reason WHY there are slower data speeds on non-stock based ROMs?
Laugh at me if it's a stupid question, but I'd still like to know...
Thanks!!!
hahahahahaha. alright i'm done

Actually, I'd like an answer to this. Even though I've been reading the CM10 thread from the beginning, I've missed some things.
I'm glad the OP asked this in the Q&A forum instead of clogging the original thread. Thanks for being a **** to him, though.

Even tho I been following alone with cm10 development and what not, no one has give us a straight answer, my best bet would be the reason is that cm10 is only working on hspa, and those that are on a 42mbps don't get their speeds like on TW, it only makes me thing that because the galaxy nexus does the same and is build from Google like that,when you run cm10 you only see H but when you run TW customs run and have H instead 4G, you see H+ while using it,I'm not sure if this is correct but that would be my best bet

Do you think that it's something that they're working on; something we can expect to see eventually? Or do you think that we'll always only have 3g speeds with a CM based build?
Thanks!!

I am on cm10 and still get 20mbps down at the same spot the factory ROM was so I didn't think there was an issue.

I have no idea we will have to wait for someone wiser to explain if that's the reason or not, Tmobile has hspa, hspa 21mbps and hspa+ 42mbps, I think cm10 works with 21mbps but not 42mbps, I haven't seen anyone go over 20mbps, I have gotten up to 14mbps tho, on stock I have an speed test for 26mbps

But yeah its known to happen on CM even the newest build hasn't been "fixed" yet.

Thanks for the replies, everyone.
There are a few build.prop edits floating around that are 'supposed' to improve data speeds. Has anyone had success with them?
I tried a couple and got absolutely no where.

Interesting...
Are you running the clean nightlies or a modded build?
I'm on the latest AOKP from WhitehawkX and I'm getting 9-11mb down. Better but I was getting 17-20 stock roms.
Sent from my SGH-T999 using xda premium
I've seen this asked in a few different threads now and some are saying that the CM devs are not planning on directly addressing this problem until they have a stable build worked out. Of course I can't say how true this is but I've seen it a few times now.

Goodbye guys.

Thanks for having me, it's been a really nice run and for the 3 days that I had semi-official JB it was amazing. Unfortunately, I lost my phone this morning and Lookout wasn't installed because of a problem with build.prop in Jedi Jelly 2 or something causing Market problems with not letting you download certain apps. Hopefully, I get a GS3 as my replacement. Anywho, thanks again guys, I wish you the best and oh, you can use anything I have done in your ROMs.
how much you pay for the s3?

Can't t-mobile trace its location? It's still connected to the towers right? And data is on? I'm sire they can pinpoint its location with some serial number or imei.

They won't do it. I lost my phone a couple months ago. I asked, they said they can't. Personally i think it was bull. Looks like they got some thing with lookout if you ask me.

idk what happened to the signal..

i was rooting my friend's s2 and he wanted paranoid android. so i downloaded that, installed the rom and gapps and his signal gave out. he had the phone for over a year and he used it to tell me he was outside so for sure it isnt stolen. i thought maybe it was the rom so i installed slim bean and still nothing. i tried my sim and nada. i didnt mess with any of the apn settings. the signal with no data would come in for about 3 seconds then give out again. maybe i should update the firmware? would anyone know where i could find the latest one? im so lost hah.. thanks xda community

Unrooting

Just got my t999L today, and almost done pulling all the data off the internal card. Would like to unroot it before I send it in the return sleeve but i want to ask what exactly is a Flash Counter? I see a few threads saying how to reset or avoid tripping it, but nothing quite explains what it is. Should I bother resetting it for a simple warranty exchange? And I assume I could simply do an Odin stock flash and that will take care of my unrooting issue?
Triangle Away will reset it.
THEN odin the stock firmware.

By the way, how's the t999l? Notice any big differences in download and upload speeds?

No no doc, please keep the answers coming! Wasnt compaining XP
And yes actually I have noticed great increase in speeds. Certain areas getting as much as 30up and 15down. Others are about the same down wise but the up speed has greatly increased.
Even if the speeds were in fact the same, I love that only select few roms work and there are bugs aplenty. I grew somewhat bored of everything working perfectly on the standard t999. Its like having the evo 4g all over again! Time to be a test mule

After some searching I can only figure out that sprints s3 and virgin mobile phone are the same, true or false???
If it is true does that mean all the work here will work on my phone

Radios are different, I believe virgin is more like Boost. You can use ROMS here but you must remove asserts from the ROM 1st to keep from getting errors in recovery.

You should definitely read post 1 and 2 carefully HERE. A lot of info to take in. I know from experience that you can only have 3g and MMS, or 4g and no MMS on AOSP roms. If you flash the 4g fix it breaks MMS.
