[Q] 3.6.21 MIUIandroid Cell Connection - T-Mobile, Samsung Galaxy SIII

I'm running the Miui v5 rom and it works great in every way except my cellular connection is rather unstable. I have a T999L and I flashed the LTE modem after flashing this rom but it didn't seem to help.
Any advice? Thanks!

If its a rom issue, most likely you'd probably get more help posting in the thread.
Shouldve been no need to flash the modem unless you specifically did something to yours. The rom wouldn't have touched it.
You certain its not a network issue. Maybe they just started working on the tower nearby and it has nothing to do with the phone.
Call support to ask.

[Q] Intermittent Data connectivity issues (Telus)

Hey guys, for the past few days, i have been getting disconnected from data services from Telus (Montreal area)
It puts me in roaming but i still see the Telus network ID. I need to reboot the phone to get it working again.
The first time this happened was on Mr.X's Stock Telus ROM. I switched to the MIUI ROM and im still getting the issue. So im beginning to think is a network related issue.
Anyone else having this particular problem?
Just curious,
How long has this been going one? Are you using a Telus radio or flashed any other??
There has been the same problem with flashing TMO ICS radio's

No Signal after Flashing Jedi Jelly/Blaze LB7 Radio/Skyrocket JB Port

Hi, after I flashed the Official Skyrocket port for Hercules and the Blaze LB7 4G radio, I do not have signal. I had signal whenever I was on the ported rom, however, after reverting back to CM10, Jedi Mind Trick, and even stock rom, I do not have signal at all. Does anyone know what is going on and if there is a solution to this?

Did you reflash your usual radio after flashing back to jmt or cm10?
Try a different radio

This happened on my daughters LG Mytouch. Its a T-mobile issue. Call them and say you lost signal, they'll fix it on your end, reboot your phone, and you should be good
Well I get a signal after a fresh install of a ROM, but after a reboot, it loses signal. Is that the same Case as with your daughters phone?

No, it had CM9, then I put CM7. Nothing. Signal never showed up till I called T-Mobile.
Did you wipe system when you flashed rom? Fix permissions....and try flashing the radio a couple times. Tried other known good radios.
Other than that....try the call t-mobile suggestion.
Dis you check your apn settings

I've tried flashing other good radios but it leads me to the same problem. I guess it wouldn't hurt to call tmobile
I'm not an expert....but if u install rom and radio...I don't see how any previous roms or radios can affect your phone. but maybe im wrong. I did have to manually add my apn info flashing telus radio on jedi jelly. Maybe you have to now for some reason??

Same problm but mine didnt even workd after uvlc8
And your sure you have no signal? I only ask because you know that one the new SR JB ports like Jedi Jelly the signal bar shows that it has no signal, but in reality it has normal signal.
Mine shows no signal, but I have full signal in reality.

in reality it shows no signal and when i search and try to register on network it wont. and same happens on stock.
After doing more testing and flashing on different roms, I think the problem for me might be that I only use the GSM/2G networks rather than the WCDMA/GSM auto or 4G/HSPA+ option. After switching back to the WCDMA/GSM auto option, it seems to work and I get a signal on all roms except skyrocket ports...I wonder why it does that. This should definitely be looked into.
Skyrocket 4.12 roms work...but show no signal. It's a known issue.

[Q] Issues with LTE on CyanogenMod 10.2

Hey there,
I hope someone can help me as I'm sort of at a loss. I just flashed Cyanogen Mod 10.2 and everything is working great, except this issue I have with LTE. When I am in a LTE coverage area, or places I would normally have LTE, instead of getting 4G or 3G, I get no data at all.
I've tried wiping the phone and reflashing the ROM. In my mobile network settings, I don't have an option to choose LTE/CDMA/EvDo or any other kind of setting either. Does anyone have any idea would cause this and how I would fix it? I would be very, very grateful even if I could set it to EvDo only so that I could get some data. Thank you, to whoever helps me.
From what I've been reading there are some issues with 4.3 and Sprint data. The powers that be are working on it so my advice is to find a working 4.3 or even 4.2 AOSP and keep reading. The brains will have this issue fixed soon I'm sure.

I'm having the same issue.
I never had a problem on the unofficial builds though. The toggle to switch between different CDMA modes is gone too.
Same Issue Here.
Same but I switched Roms , for know I'm just waiting for a fix

[Q] Galaxy S3 ##72786# reboot issue?

Flashed my Sprint Galaxy S3 with Wicked Sensation Rom Mk3 v.01 and then v.02, both ran fine... then I did a ##72786# the other day while at home and my S3 went nuts. Contiuously reboots and cycles all the way to the lockscreen, then reboots, and reboots... went as far as to odin flash back to stock, unrooted, but reboot issue continues. Reflashed MK3 Modem and wicked, same issue. The one time I was able to actually get into the phone settings, everything under About Device/Status stated unkown, not connected, etc... However.. whenever I leave my home, the reboot cycle stops and everything appears normal. Seems to be a radio issue, and I'm trying to isolate whether it is 4g specific... Has anyone out there experienced the same or similar issues?
Sprint Galaxy S3
Wicked Sensation Rom MK3 v.02
L710VPUCMK3
Kernal Version 3.0.31-dkp-geb5b561
Update... The issue has nothing to do with ##72786$.. I flashed Wicked 4.3 v.02 on my daughter's S3 and having the same issue when she comes into our home. It's definitely a 4G issue. Again, anybody on Wicked Sensation Ron 4.3 v.02 having radio issues????

Sounds very similar to the problem I'm having and I described here: http://forum.xda-developers.com/showthread.php?t=2609888
I stopped the constant reboots by flashing the stock kernel bundled in the MOAR ROM but that leaves me with little to no connectivity to Sprint's tower. I do remember that the Sprint tech told me the new update was causing problems with 3G and 4G handoffs on some S3's but it continues doing it even in CDMA only mode. I've already tried flashing the stock MD4 ROM with the MD4 firmware/modem/kernel with no improvement.
I'm not having the issue in cdma only mode... In either phone... and I have learned my mother's stock S3 is getting no data signal in my home. Appears there is a tower issue in my area. Good job sprint... good job.

As Jessooca stated, if you are on an MK3 Rom. You should flash the MK3 Modem. You can find it HERE.
Yes.. original flashed mk3 modem... THEN 4.3 rom. .. pretty sure there is a tower issue in my area.

[Q] force roam onto Verizon towers with sprint s3?

I remember seeing a thread on this a long while ago but my search has turned up nothing aside from qbkings video, but I see that a touchwiz ROM is required, I'm using an aosp ROM and was just curious if there's still a way to do it on aosp, or if anyone can pm me with some direction, I'd really appreciate it. I'm stuck out in the Boonies with no signal other than WiFi.

You can do a Nand Backup, and flash a TW Rom. Then you should check out THIS thread. BTW roaming constantly can get you booted from Sprint. Have you tried calling Sprint, and asking for an Airwave ?
