4g problems! - Thunderbolt Q&A, Help & Troubleshooting

So my tbolt has been acting weird lately. I am using synergy ROM with 2.5 radio and have never had any real issues. These past 3 days however my phone has not been cooperating well. When charging it will sometimes turn off and will not turn back on for a while. Also when I did get it turned on this morning I had 4g for a short amount of time then it went away. I now only have 3g and want to have my 4g back. Does anyone know if greensboro NC has no 4G today? And any solutions to my problem would be helpful!

if you updated the newest Synergy, it runs off of the latest 2.11 build. that being the case, the 2.5 radio might not work very well with it and i suggest switching to the new 3.5 radio.

[Q] Radio question

I'm new to the Thunderbolt world. Previously learned all I know from my old OG Droid. Then relearned all from my Droid X. Now on a tbolt. Learned all about this now. Currently running das bamf 1.6.3 and loving it. Sure would love gingerbread but unsure how daily cm7 is.
Anyway my question is this whole bit about radios. I read thru the radio thread and many others but still unclear as to what/which I should be running. I took a screenshot of my settings/about page that shows my current radio.
I'm not in a 4g area. I have not had a single reboot since i got the phone 13 days ago. Been running bamf since 9 days ago. from what i can tell, I'm on the old radio but thats where i get confused. this thread http://forum.xda-developers.com/showpost.php?p=13093559&postcount=1 has different setups and i'm unsure of what one to go with or if it is even necessary to change anything.
Any help would be great. I've been a lurker here for over a year but never needed any help until now. got to get my post count up haha. Thanks guys.

You're on the old radio, if you look in the baseband in the screenshot yours ends in r which is the stock version. The new one ends in w_1.
Im like you, i don't have 4G available to me either. I flashed radios and all i got was reboots. Flashed back to stock radio, reboots stopped, but tethering went to ****. I flashed the 2nd or 3rd radio down on the radio thread, an so far i have not had any reboots. So if its not broke, don't fix it, but if you must try the radios, do it in consecutive order down the list til you find one that works.
I really like the second radio from the top, it seemed to help my GPS lock on faster and I have a better signal. I also had issues of random reboots with the leaked new radio, so far with the second one on that page no reboots and increased performance.
Thanks guys. That's what I figured. Everything is working perfect...gps, calls, even 4G just worked driving thru easton pa. Nice to have everything working but addicted to this stuff lol.
Maybe I'll just leave well enough alone for now. Very happy with the tbolt but would love to see 2.3.3 or .4 with sense. Loving bamf remix but missing gingerbread from my Droid X. Damn phones. Wish I could have multiple haha.

Figures. Soon as I go getting cocky, my gps starts acting up. If I go to Maps, it finds me just about instantly. However if I go to navigation and click maps or driving directions, it says searching for gps. After 2 minutes I just backed out of it. Nuts.
Gps (first time I tried navigation on 1.6.3) worked perfect on 1.6.1. Why would it come up instantly on maps but not nav? Damn. Downloaded all the posted radios. Hoping I didnt have to use any...

Flashed all listed in link. Gps still says searching on every radio. Going with link 1 for now and see how it goes.
The last link in the link I posted is the stock radio/baseband, correct?
Sent from my ADR6400L using Tapatalk
I flashed the first radio on the list but it didn't update my LTE radio. Any thoughts why?
Unsure. I'm currently on the radio in link 1. Going great. Unsure of LTE changing. I don't have 4g here so I can't test if and how it works. Not sure how you check which LTE radio I have anyway... sorry I can't be more helpful.

No matter what I do.. the software and build number don't change.
Thanks for the response.
Just got the Gingeritis Rom, which is a 2.1 sense 2.3.4 gingerbread Rom, and getting the radio to work properly was a pain.
Just noticed my 6 bar reception in Bamf changes from white and full at my house to none periodically. Seems like it does out for a second. Maybe time for stock kernel again...

Rooted tbolt puk code?

when I first rooted my tbolt( a month ago ) 3 days later still running stock rom I plugged my phone into my car charger and left it for about 2 hours came out and it had puk code with the pic of the sim. I just went into cwr and wiped everything and restored the backup that I made. The puk code was gone and phone worked fine. My question is, no matter what room froyo or gb my 4g speed sucks. I'm in pittsburgh pa and everyone else has ok speeds. Should I get the sim replaced?

Could be a possible Radio issue. Especially if you're stock.
I'm currently on the newest radio for gb mr2 running candy 3.5.1 and it is just as slow as stock froyo radio on stock
Sent from my ADR6400L using XDA App
Could definitely be a ymmv kinda situation with your 4g speeds. I am running the PlaneJane ROM with the new MR2 radio as well and honestly I have been experiencing weird things. My facebook app and mail sync seem to be quicker, but things such as youtube and the web browser seem slower. Youtube even cuts out with an error at times and it never used to.
Adrynalyne has this thread that you may find some radios that are a better fit for you and give you better speeds, or some of the other GB roms may have other options as well.
I just would be kinda surprised if your poor speeds are in relation to your sim.
Thanks for the help

GPS fix for iCS ROM's

After many weeks of GPS not locking, or taking 5 plus minutes to lock on the recent leaked AT&T ICS ROM's I have found the problem. Not everybody has a problem, but many of you do.
No matter what I did, GPS simply wouldn't work. Flashing back to stock, re-flashing several ICS ROM's with complete wipes of the phone including EMMC and SD card did nothing. The last AT&T leak, as well as the official did nothing to fix the problem. As soon as I flashed back to sauROM or any gingerbread ROM, GPS would start working perfect, with 6 second lock, but back to ICS and GPS would quit again. Last week I finally found and fixed the problem. I flashed the radio from the gingerbread bread ROM on several ICS ROM's including the new official, and it's worked perfect for the last week. The UCLF5 leak and the New official AT&T ROM. I'm running Flapjaxxx ROM with no issues. GPS locks in under 10 seconds, LTE here in Tampa, FL signal strength is the same as is LTE giving me 21MB down and 12MB up, on this UCLA1 radio. Just because it's an older radio, doesn't mean performance is effected.
Flash with Odin (I'm using v1.85) Don't unzip/extract and place it in the phone space, NOT PDA
Make sure phone is in download mode and you have the samsung USB drivers installed.
Nice work, The quirky inconsistent ics- GPS behavior is consistent with your discovery. I've had Stellar gps on gingerbread, but i have yet to test the gps with my newly flashed cm9 rom. If i experience the degraded performance being reported, i will give your procedure a go. Thanks for taking the time to shareware your findings.

Having had mostly good but sometimes quirky GPS since running Flapp ROM based off official ICS and having nothing better to do at 1am I gave this a try. I will say that on ICS I had either gotten a quick lock or it would take 15+ seconds to over 5 minutes for a lock and it varied with no pattern I could notice (reboots, charging status, time since last used, etc.). In another post I had noticed that my 'in use' satellites had decreased.
Initial results seem positive. Got more satellites 'in use' according to GPS test (compared to just prior to testing) and locks are back down to a couple seconds. Will be able to try it out again tomorrow after the phone has been on charge all night and I can drive with it. Maybe it's voodoo but If nothing else it doesn't seem to have worsened anything.
Urkk..

Same here! I flashed the GB radio on top of Flapp's ICS official ROM and GPS locks like it did when I was on GB...awesome! This kind of reminds me of my Blackberry days, using different radios and even hybrid ones, lol.
I also claim this as fixing my problem. Thanks @ OP!!
Didn't work for me. I had to flash back to uclf6.

Ok for two days using the Ops conf no change it still doesn't lock on under 16 minutes

I have tried this on my last note and it did not make any difference. In the mean time at&t replaced my note and this new replacement seems to be working better so far. However, flashing this modem it takes a while to connect to lte network after reboot but once it connects it works fine.
i will report back tommorrow, need more time to test 2.3.6 UCLA1 modem.
after i flashed ucla1 radio, it locks really quick! then again, i always get fast locks after a reboot.
let see if it still fast locks tomorrow without the reboot.
Thanks a lot. I was having GPS issues where the connection time was taking at least 10mins or more and at that rate I'd reach my destination before I'd even get close to a solid lock. With this radio I am now getting 2 to 6 second GPS connections.
Works
I have been using this for a week... Even before the op posted. Locking satellites as it should when I was using ginger bread. No issue so far with xalls, text, or LTE. However, I found that during navigation with google nav, co pilot and waze. The tracking was drifted, lag behind. Not significant but you miss a turn if it freeze at the right moment. I kinda pissed that they screwed up one of the important function of the phone. Iused this daily so kinda frustrated. I meed to send complain to ATT and Samsung. Just wondered if ATT and Samsung are awared of thi issue.
I dot think its the modem I have tried it. I am on the official CM9 and GPS locks within seconds inside my house using the uclf6 modem.

Thanks for the idea, lf5 working great for me.

Just to verify the GB radio works great paired with Flapps ICS ROM (official), I tested it as I drove around the city today. I was getting instant locks and accuracy within 10'. I honestly get the GPS locks I did on GB! It really works on my device WITHOUT ANY ISSUES and as with all things, ymmv.

Broken 4G data on AOSP roms

I've had my thunderbolt for over a year now and its been rooted for most of that time. Up until recently everything been working fine. I was running CM7, but for the past few weeks I haven't been able to get data when connected to 4G. The 4G icon shows up but is grayed out, but when I toggle airplane mode it turns blue but still does not work. My first though was that my radios were wrong so I flashed a bunch of different radios but none of those worked. Next I tried flashing a bunch of different roms (all AOSP because I hate sense), no help. I finally figured it was my SIM card so I got a replacement from verizon.
So none of this worked and on a whim I decided to flash a sense based rom, and 4G worked!
Is this a common problem with thunderbolts or does anybody have a fix for this? I really want to switch back to CM7 (running MIUI with no MMS right now).
EDIT: I forgot to mention, for some reason 4G data works on the MIUI rom I'm currently running. So for now I'm opting for speed over MMS.
For anyone interested my radios are currently:
LTE: 0.01.79.0331w_1
radio: 1.49.00.0406w_1

Hello,
I have had my tbolt rooted for over a year as well, I am a flashaholic and never had a data problem, maybe u need to switch ur kernel, I'm on ziggys kernel and I've been on since it released and never had a problem, I never really changed my radio, hope this helps.

There are 4G issues with AOSP, you get slower data speeds and for some reason my coverage recording maps don't record 4G properly when using AOSP. Sense works fine.

I did switch to imosyens lean kernel on a few roms after things started acting up. I don't think my kernel is the issue though, seeing as I was running CM7 for so long with no problems.

Odd that it worked for so long and randomly crapped out. You wouldn't happen to know of any fix or work around to this problem, would you? I really just can't stand the notification menu and icons that come with sense.

Newly rooted TBolt won't find 4G?

Hey guys. Little new to the TBolt crew here.
I've been rooting for a bit. Did an HTC Hero, a DROID Eric, an Incredible... Now I've got a TBolt sitting here that I just rooted about an hour ago. It was running 4G just fine both before and after the root, but after installing a CM7 ROM (SFK's to be precise) I haven't seen 4G pop up since. I've tried a couple other CM7 roms, but nothing seems to make a difference - it only runs on 3G.
I was thinking it might be a radio problem, but admittedly I'm pretty novice with this stuff. I just flash what sounds interesting, and if it's not as stable as I'd like I find something else to flash. Does anyone have any ideas what's wrong? And what I can download to fix it?
EDIT: After giving up and deciding to go back to my backup of "stock" that I'd just made... now it's failing to properly back up. This wonderful error about data being corrupted with the only button available being "I'm Feeling Lucky" and still no 4G, only 3G. Now I'm at a complete loss.
I have a Nexus sitting next to me clearly connected to 4G just fine, so I know it's not a network issue. What the heck is going on here?
I'm sure you have, but never know... have you checked your wireless network settings?
Settings--Wireless & Networks--Mobile Networks--Network Mode.
Make sure LTE/CDMA is selected.

most roms are built with a specific radio in mind i would try to flash one of the newer radios they work better drain less battery and are more compatible with rooted roms.
