Can't get 4G on previously flashed VZW S3 on 4.3 - Verizon Samsung Galaxy S III

The phone was previously flashed to selectel, I have Odin'd the 4.3 stock TW ROM, but the phone still won't get 4g on a contract Verizon line.
When reading the phone with the sim out (with CDMA Workshop) I can see the old flash is still present.
When reading the phone with the sim in (with CDMAWS) I can see parts of the old flash.
I have a feeling that my EVDO Rev, Mode Pref and a few other things are not set properly.
Any help would be greatly appreciated. If someone has an S3 and can read it with DFS or CDMAWS and let me know what settings you have that are working for 4G I would be extremely thankful.

Well I've never seen that tool before in your edit.
But a much easier fix I think would be to just (re)flash the correct modem to your device.
Glad you got it working though.

[Q] captivate radio set wrong after flashing t-mobile ROM by accident - no backup

so like a kid in a candy store i got ahold of ROM manager and ODIN and started flashing cool looking roms..next thing i know, the t-mobile logo is popping up and i am a not-so-proud owner of a modded T-Mobile Captivate, no longer an ATT Galaxy S!
of course the t-mobile network uses different frequencies and the like, so the phone part of my phone stopped working...bummer! i grumbled as i flashed back to a ROM that worked with the ATT network (FUSION it is called) but apparently that ROM does not mess with the internal network settings thats why it worked so well initially it didnt change the stock cell internals...
so now i have a hybrid phone, half-tomobile half-att half Fusion, and it only picks us signals from the Edge network!!! i barely get any reception so it pretty useless...
so i need some help...i can i get this beast back into a condition where is will work as an ATT galaxy?? also, for whatever reason i cannot mount or download market apps to the phone tho it does pickup wifi connections...
any help/ideas appreciated...advTHANKSance!
- mark
Flash back to stock with odin 1 click. Or try just flashing a new modem with cwm.

ok...i finally fixed the mess i made by using this process...

PLEASE HELP! 2.3.4 and suddenly can't connect to my network (Bell Mobility)

Hello,
Please help if you can! I updated my Nexus S to 2.3.4 the other day, and everything was working fine. Today, the phone at some point lost the ability to connect to my network (Bell Mobility). I was out and about and was turning data off, and might have hit the 2g/3g toggle by accident, and seem to remember reading about that causing problems - though I have no idea if I did for sure (the sun was bright) and am honestly not sure what's wrong EDIT: when I go into wireless & networks\mobile networks\network operators, the phone will only recognize Roger's Wireless (and it was bought at a Telus store!) The UI still works fine, and I can still connect via wifi - just no way to get it to recognize Bell's network
As stated above, everything was working fine this morning - voice, data and sms all good. Here is all the info from my phone:
Android version 2.3.4
Baseband version NO DGSXXKD1
Kernel Version 2.6.35.7-ge383d80 [email protected] #1
Build number GRJ22
The bootloader is unlocked, and I had been running CM7 before flashing the manual 2.3.4. I'm not sure what to do. Tried re-flashing the manual 2.3.4 update.zip, and nothing. I know a very little bit about rooting/flashing (just enough to follow guides), and am wondering whether I need to re-flash a different kernel/radio/rom or something. I did search, and couldn't find anything that outlined my problem exactly (I do apologize if something is out there and I just didn't look hard enough).
Again, the phone was bought new at a Telus store, and found the Bell Mobility network out of the box no problem. Am hoping someone can help!
Thanks so much for reading, and if you are able to help.
Check your APN's to make sure the data info is in there I had to manually enter mine (bought phone from Telus to use on Bell/Sasktel's network) for Sasktel and bob was my uncle
Every upgrade i need to put them back in. No automatic for me, so i would start there
Menu - Settings - Wireless & Network - Mobile Networks - Access Point Names.
If nothing is in there, you need your APN settings. Talk to bell support for the info, and they should be able to help you over the phone (they support android even if they dont sell a Nexus S)
Cheers!
Thanks so much for your response, though I don't think that the APN's are the issue at all; they're still in there and fine. I think that it's the actual radio (or baseband), as the phone will not recognize the bell network, only the Rogers network (and it was bought new at a Telus store!)
I think that I need to re-flash the radio, and maybe the kernel. I searched to try and find the radio image for my phone, but haven't found anything clear enough for me to be comfortable to try - I've read time and again that flashing radios is one of the riskier things to do. I don't think that my phone is bricked (can still boot it up, and all of the ui works and can connect via wifi). Don't want to risk doing more damage.
Thanks again for your response though!
i think i'm having the same problem. i've manually upgraded to 2.3.3 then to 2.3.4. and then i put a sim card in - not used it as a phone before this.
i can get 3-4 white bars lit up but can't connect to any network. the bars turn green when wifi is active, but still can't connect ("can't connect at this time. please try again later" toast appears). not sure if the phone is borked, or if the upgrade wasn't that successful.
I actually have this same issue but using it on at&t in the USA...Really hope it isn't broken cause I have no way to fix it since i'm not in canada
Maybe check if the 2g box is checked in mobile networks. Check your apn settings and if that doesn't help try and flash another radio.

i'm unrooted, and don't intend to root. apn is fine as suggested above, and regardless of 2g checked or unchecked, still no connect
Rogers is the only 2G gsm provider, your phone may be stuck on 2G. If you have the choice, I would go back to 2.3.3 full stock and see if everything then works.

No. you are best to use cwm and restore a stock image for your phone
Sent from my Nexus S
Your best option is to flash back to 2.3.3. Download rom manager from the market and flash clockwork recovery. Once in recovery flash the 2.3.3 .zip file. I saw it somewhere here but i forgot where I saw it. Hope that helps.

Try this http://devsforandroid.com/index.php?board=18.0
I'm NOT SURE if it'll work, but it's worth the try. Make sure to to wipe everything before you flash. I'm not responsible for any damage this may cause. But I hope this helps you out.
If anyone wants to chime in and correct me please do so.

Or if you're not comfortable flashing the stock 2.3.3 rom maybe just try and flash back the xxkb2 radio which I believe was the stock baseband for Rogers, telus, Fido and bell. I have the .zip file for you to try and flash through CWM if you need it. Otherwise you can find it somewhere here aswell.

i'm not looking to root nor use any 'hacks'. i don't trust them.
under the battery, the phone is just a i9020. no letter afterwards.
Flashing a ROM doesn't require root, it requires unlocking the bootloader, which Google officially allows you to do that. You can unlock the bootloader, flash 2.3.3 ROM, then lock it as if it had never been unlocked. Just keep in mind that unlocking resets to factory default and wipes your SD card clean, backup before you do it.
Ahhh yes, I had same thing except with Telus I fixed it once, but the second time I could not get it to work, do this, flash this radio
http://forum.xda-developers.com/showthread.php?t=1044261
it is the stock radio your phone came with, then call up bell and get them to "repush" your sim card... hopefully you will see your network again.

It depends on which ROM you flash. I flashed the official 2.3.3 ROM, it contains the radio image, it'll flash it as you apply the update.
Do you remember which baseband version it came with out of box? That should give us hint as to which radio applies to your phone. I think there are really only two types of radios used except NS 4G, 850/1900/2100 (i9020A radio) and 900/1700/2100 (i9020T radio). You can ask your service provider or check out their website which band you are running on.
Back to flashing ROM, I just realised you don't even need to unlock the bootloader if you are flashing Google signed files. You should most likely be able to flash a 2.3.3 full ROM, then flash the 2.3.4 update file. But if you find the 2.3.4 full ROM, that's even more convenient. I saw a full ROM on the forum, but I that was for i9023 or i9020. Not too sure, maybe others know.
For the Canadian carriers, as stated before, Rogers is the only 2g (edge) carrier all others (Bell, Telus, Sasktel) are 3g (HSPA). go Settings>Wireless & network settings>mobile networks and ensure "Use only 2g networks" is not selected.
If this does not work flash the KB2 modem, the other modems may lose 850mHz spectrum which could be causing your grief.
Solution!!! (At least this worked for me!) - Didn't have to flash anything
Hey all,
I apologize for not posting this sooner, but found a solution that worked for me, hope it might work for others experiencing the same problem.
**PLEASE keep in mind that though this worked for me, I don't know if it will work for you (maybe it might make things worse for some people). Especially keeping in mind that I DON'T KNOW FOR CERTAIN what originally caused the issue for me, nor what specific factors (rom build, phone model, radio image, etc) might have contributed. As well, I am on the Bell Network. USE ANY OF WHAT'S STATED BELOW AT YOUR OWN RISK. Disclaimer stated, read on...**
In the dialer, I punched in *#*#4636#*#* and then from the menu that popped up, selected Phone Information.
From there, in the Set preferred network type: drop down menu (scroll down a little, you'll see it) I selected GSM/CDMA auto (PRL). **Again, remember that I'm on the Bell Network in Canada. Should you be trying this, these settings might not be for you. Again, AT YOUR OWN RISK**
Then, still from the Phone Information screen, I pressed menu button (the hard menu button on the phone), and then chose the Select Radio Band option. From there, I believe I selected Auto, though I may have selected USA (It's been a couple of days, and I can't remember, I apologize).
After that, went back to the Phone Information menu, and pressed Run Ping Test. It seemed to show all of the necessary (and appropriate for my network) settings as ok, and... everything worked!!! Full network connection as before!
Hope this might help someone else! Keep in mind that I'm not sure what caused the original problem; I do believe I remember pressing the 2g/3g toggle, and also remember reading somewhere that this can cause problems. Specifically, that it stopped peoples phones from going back from 2g to 3g - in my case (Bell Mobility) there is no 2g network to drop down to, so if it got stuck on EDGE mode, it probable looked for the only local carrier with a GM EDGE network, (Rogers) and got stuck there. Not sure, but maybe this is what happened. Any wise folks out there that might be able to confirm/offer insight?
Anyhow, thanks so much for all the responses and offers of help!

Skyrocket No Sim Issue PLEASE HELP ANYONE!

Ok guys,
I just bought a skyrocket today, unlocked it to Tmobile. Phone worked great for a while, then I rooted it using doomlords easy root method. The Phone restarted, ever since my sim is not working. I tried EVERYTHING. My sim is working in my brothers skyrocket, its not my sim card. My IMEI and everything else is visible, my baseband is visible. I tried everything I did a factory reset, I flashed to sky ICS successfully and still no luck.... I've been at this for 5 hours now, someone ANYONE please help me! What do i do?
Does your brothers sim work in your unlocked rocket? Maybe try odin back to full stock and see if it works
Sent from my SAMSUNG-SGH-I727 using xda premium
is your sim not working or your data not working ? Those are 2 different issues. Does it day invalid sim. Or no sim . Or is your data just not working
I've had a similar issue while running Sky ICS where it told me to insert a sim. Try flashing a t-mobile radio and see if that helps. I believe someone posted the t-mobile KL1 and the Telus KJ3 radio on one of the other threads that worked for me.
Did you ever get it working? My brother is having this same issue on a skyrocket I just sold him. Just says NO SIM. He tried flashing the t-mobile radio's but that didn't work, and is actually what caused it to start saying no sim.
Another thing...did your skyrocket ever show a yellow triangle after rooting? His didn't, and I thought they should show a yellow triangle at the startup after rooting like other samsung phones.

I never got a yellow triangle after rooting my Skyrocket. and I had that issue with the sim. What I did was delete the APN and redid the APN manually. If on tmobile let me know, Ill get you the APN or you can google it. Also, I use the Juggernaunt 5.0 ROM...worked like a charm. BUT..I did notice that Im not gettin full 4g speeds as I thought...but faster than edge!
So you had a No Sim issue, but it resolved by deleting and manually setting the APN? I'll try that tomorrow, hope it works.
So I fixed the no sim issue...I changed the radio...and it recognized sim but still wouldnt let me set the mobile network and connect to any network (no calls, or internet). So I tried Juggernaut with a tmobile radio...had to manual select tmobile as the mobile network...super poor internet speeds...only 2g.
So I adjusted the bands (dial *#2263#*) to WCDMA 1700, and now I get full 4g speeds (~3500 kilobits per second from a speed test). Woohoo! Thanks everyone.

[Q] SCH-i705 No Data Connection

Hi there,
First post where I feel like I've tried everything and about to give up. Bought SCH-i705 Verizon tab 2 7.0 with LTE, I live in Canada in an LTE metropolis with TELUS service, I rooted the tablet according to here which was successful.
I never was able to edit/add APN's (there was nothing showing or options to do anything on APN setting page...so then made a few edits to build.prop with two lines where I can add/edit and return to default. (ro.sales_code=LOL and ro.csc.sales_code=LOL)
I've edited the apns-conf.xml file a ton of times, made adjustments all over the place comparing to my other android units and forums for TELUS apn settings. I disable the Non-Verizon Sim Card alert just so that I could feel better about maybe getting somewhere.
I'm a noob (and a girl) and this is the first root I've ever done JUST because I couldn't ever obtain LTE/3G data connection. WIFI is great but I bought this unit for the chance to be mobile with it.
Tonight I thought Mr. Hyde's Modem change here would kick it in the butt but still, reboots continually give me "No Internet Connection" errors. Is there a way to tweak in build.prop to get this functional? I really don't want to have to set up a hotspot for this puppy when on-the-go.
Thanks in advance,
Lisa
What i would do is do a clean flash of the rom again before trying various modems. MrHyde03 has two modems i believe that he has posted for the sch-i705 one is the g3 and one is j1. If youve downgraded to g3 i suggest flashing the newer j1 before you reflash his rom. after you have the current up-to-date modem flashed then boot into recovery and do a factory wipe. also make sure to go into mounts and flash the /system. Try to flash the rom again after youve done this before attempting to mod the system since there are no other post for internet connection errors in hyde's thread.
I ran thru doing a clean flash of the rom and steps you outlined. Still no avail... One thing I noticed this time on the locked screen was "searching for service"... when I went on to attempt to add my APN with the 2 lines from my frist post into build.prop so I could add my APN settings, the "searching for service" went away.

<bump> hadn't heard if anyone else had any other ideas to get data working. I don't have a way to test whether a data connection functionality is even possible as outside of Verizon territory at this point. Any other Canadians in Bell/Telus/Rogers regions playing around with this specific device?

[Q] ATT SGH-I747 Hotspot Issue

Hello all, I am new to this site and have a situation I could use some help with.
Last year I bought a new ATT SGH-I747 S3 in the US. I had it unlocked by T-Mobile and now use it in Ecuador.
Here are the facts;
ATT SGH-I747
Android Ver. 4.4.2
Base Band I747UCUFNE4
Kernel 3.4.0-1514807
[email protected] #1
This is the problem, I recently bought a Samsung Tab 4 to use for work. I intended to use the wifi-tethering between my S3 and Tab4. When I try to select hotspot I get a message saying "no data plan and or bad sim". Everything else works fine.
I went to my provider and they said the phone was broken!!? I went to a tech and he said that my provider is NOT in fact a 4G network as advertised and I would need a root to make it work. I have tried several apps to solve this but no luck.
I read that the CM11 Rom would correct this issue even in a NON rooted device, this led to several others issues; can't use Rom Manager on this device, can't make backup without root, I did finally find an app that would allow me to save my efs file but from there I have no idea what to do. If push came to shove I would lean towards rooting and using CM11, if it would solve the hotspot issue.
I have read several one click root, one click this, that posts but they seem to leave out some important pre root steps, like backup, efs file saving etc. At this point I am at data overload and could use someone who can give me the straight no B.S. this is what you need to do steps to resolve this. I am very good with electronics, but phones are not my forte.
Any assistance will be greatly appreciated.
Thanks,
