3G/H+ issue in AOSP ROMs - T-Mobile, Samsung Galaxy SIII

Hey guys, I guess this has been reported before but I've never seen solutions or explanations for it. On AOSP ROMs, data works when it displays "H+", when its in "3G", it stops working, but thing is, sometimes I have to turn off data and back on again for it to work properly because it stays stuck in 3G

That's a rom related issue, not all aosp ROMs have that issue.

Yep, that's the fix I used to use.

Also, simply toggling airplane mode on/off can help. Itll ensure you are connected to the best possible tower.

Using latest md5, can I use that old team sonic flasher that's around here? Also, I've heard of some people saying their phones get hotter with md5, mine does so too, any ideas on that?

You can use it, though it hasn't been updated in a very long time. Only thing we know of so far for the md5 heat issue is to use a different modem.
You can flash any modem as long as it is for your model.

Yep just flashed the previous one from md5 from your thread (ljc I think) and its working better. Heat is less and data seems to be more consistent

Good deal. Let us know if you have any other problems or if it starts exhibiting the same ones again.

REDICULOUSLY SLOW DATA on PA 2.51

I'm using paranoid android 2.51, and lean kernel 1.6 with the UVLI8 radio and my data is VERY slow even with full bars. Do any of you guys have this problem?

Have you tried different radio's and have you edited your build prop at all. I'm using uvlh3 baseband with the same kernel and rom as you and I get great speeds

Also, check your data usage. You may have been throttled if you went over your quota.

Try flashing a different room after you backup and see if you still have the problem... If so then Odin back to full stock and see if it persists.. If so from them go to your nearest Tmobile store and have them take a look

The radio included WILL work, you just won't get HSPA+. You'll only get EDGE.

It took a while to load a Web page and would oscillate between 3g and 4g. Now it's stable and fast. My 3g seems more useful too whereas before 3g was equivalent to no data at all.

The new radio is a lot better. I have considerably better speeds up to almost two megabits down on evdo. The statement that the os itself probably didn't change a ton except how the speeds are reported is true though.

Seems like they would've addressed the inferior radios before JB. Makes me think it was a form of throttling.
Sent from my LG-LS970 using xda app-developers app
Took HTC and Sprint forever to address the lousy radio on the EVO3d when it was released. I was surprised when I went from a Transform to a 3d and was surprised by the slower loading webpages... Yeah not a fun experience to get a faster phone to be hobbled by the actual firmware.

They probably try to do as few otas as possible, to minimize costs and technical errors. Perhaps Qualcomm released new stuff, but I doubt sprint, one of the slower networks, would want to throttle their devices.

Radios can make your performance worse as well. Perhaps flash an old one from zv7,8, or 9
Sent from my LG-LS970 using xda app-developers app
Yes they can, my phone did not want to send text messages after the JB ota, and my 4g signal sucked too.
Does anyone have flashable radios from ICS that i can flash onto this ****ty jelly bean update?

Hmm there may not be any then. I hadn't seen any, but hoped perhaps you would. Unfortunately, I can't help. My PC is down so I can't unpack the tot. Either go in irc and have someone dump the IMG or perhaps you would want to lgnpst and then restore a backup in recovery.

They have an ATT version on their webpage. I flashed it and it worked fine. I didn't stay on it for more than 30 minutes though, so I don't know if it's stable or not.
Everything on ChameleonOS works..
Flash the latest nightly and its incredibly smooth!
Its definitely a DD and never had issues with it. Got rid of it because I really don't like anything MiUi

Unknown for 4G

Precursor: I have tried multiple roms both ICS and JB.
Ever since I rooted GB27 after doing all the OTA after getting my referb I can't turn 4G on. The status goes from Unknown to Enabling back to Unknown. I have 3G just fine, can connect to Wifi just fine, just can't enable 4G. Any ideas? I've tried a couple different things I've found here but so far nothing is working. My next step is reflashing my ROM with no external SD card in.

Have you tried flashing different modems? If you are running GB27, then you have to run a jb modem. But you can't flash modems through mobile Odin, has to be done through pc or cwm.

The modem is separate from 4G. have seen something like this before and it was a hardware issue... Another instance was because of a virus protection app that was installed on the users device.
