Bad signal or No service after flashing

Hi there. My device is a i747 on Virgin Mobile (Bell) in Canada. I have no service, or 1 bar of signal (can't make calls at all).
I flashed CM10 in November. Then just the other day I flashed Synergy. Then switched to Galaxy Mod. (I followed instructions for each flash, wiped everything each time etc. even when not specified in the instructions)
Today I switched to CyanogenMod 10.1, I got stuck in a boot loop. So I reflashed back to a stock root image with Odin (root66.stock_Bell_I747MVLALH1.tar). Now I have no service! I can see one signal bar. Under status it says VIRGIN.
EDIT: Now after I typed that, I reflashed another rooted stock image, I have no service at all and IMEI shows as 0.
EDIT: Since posting I have restored my IMEI, the phone seems to be registered on the network. But still no signal just like before
EDIT: March 16: I have tried flashing modems. Then I restored to the latest actual stock (non-rooted) image from my carrier. Same thing.
Please help me out, thanks

Hello.
I just travelled by train and it picked up signals, both voice and data. Possibly because i was passing close to a cell tower. But it quickly stopped working whenever the train moved too far from a cell tower.
Then back to no signal at all.
Will check APNs, but I don't think it would start working then stop if it were a configuration issue.

Yes, the modem is not working properly. Should I flash another modem or what? Thanks.
APN is set correctly.

Yeah, sorry wasn't all too clear. I replied in a rush.
Go in the modem thread and look for modems for your carrier and start by flashing their latest.

I tried the latest modem for i747M from the thread and it didn't work, same stuff is happening. I will keep trying them. Anything else I can try if that doesn't work?

I tried about 4-5 so far. Didn't work. It's the same result. I'm not able to make any calls, it either shows 1 bar or No service.
So far I have set APNs, updated IMEI, and reflashed modems. When I get home I'm going to try more stuff.

Hi there, I just flashed this file from Samsung-updates.com using Odin. It is 4.1.1 from my carrier.
KIES_HOME_I747MVLDLK4_I747MOYCDLK4_538866_REV04_user_low_ship.tar.md5
Then I did a factory reset from inside Touchwiz. What should I try next?

I tried flashing another image: KIES_HOME_I747MVLALE8_I747MOYCALE8_20120523.225040_REV04_user_low_ship.tar.md5
and doing the factory reset code *2767*3855#. Didn't work, still have no signal in general.

[Q] I lost 4g and need help getting it back.

I flashed Sonic 4.1.1 right after I got this phone (in November), and it worked awesome until last week when I tried to flash 4.2 on it.. I lost 4g and now it mostly stays on Edge.. Any ideas...? I did all the fixes I could find on XDA, I flashed back to factory,, Factory reset it, and everything I could think of... I'm stumped and my phone is slow..

Look at this thread. It may help. You will need to be on a Tw ROM.

Thanks mrhaley, I tried removing the RAT restrictions, and switching to Automatic, then choosing all lte, but still no good.. In fact All lte made me lose signal completely.. Any other ideas before I call At&t? haha

Try going back to stock and start all over or flash your current modem/Baseband and see what happens

Choose all lte first then automatic. Since your stuck on edge select all wcdma too. Just select automatic as the last thing you do before exiting that menu.

Got It!
Great directions guys! it's working now.. Whew, I missed my 4g...

Well, you all helped me figure out how to get 4g, Now how do I get it to stay connected.. It will only stay connected for a few mins now, then it goes to E.. I can get 4 g at will now, but it won't stay connected...

Thanks for asking... Yes I did lose the IMEI, and had to restore it.. I also went to radio shack and got a new sim card. I have factory flashed and reset it and did all the steps on the link above..

Radio not working when wifi is on.

I've had this Samsung S3 for almost a year now, and in the pass week, my radio has been acting funny, It dropped the IMEI, and pretty must lost all connections with my 3G network, So I ended up wipe the phone and setting it back to the default S3 ROM, after being on cyanogen mod ROM for a few months. After a bit of fiddling, I ended up finally getting my IMEI number back, and it worked fine.... till I connected to Wifi. After I connect to the Wifi, my radio stops working period. Any ideas on what could be wrong?
I'm running a Samsung SGH-1747M, which is an AT&T version, although my carrier is rogers in Canada.

3G/H/H+

Ok so I have a Telus model and this started a few days ago when I flashed an AOKP rom...
So, I don't get LTE in my area and have always had 4G (or whatever they say it is).. Ive flashed many TW roms and ALL the roms have displayed 4g...and for not having lte, ive been very impressed with the speeds.
However, since this AOKP rom I installed (which was awesome, just wanted to go back to TW), it displayed H+...
Now, I know what h/h+ is and all that jazz about the carriers.. My issue is, can't flash any TW rom now without getting 3g/h/h+ toggling back and forth nonstop and the speeds are horrible!!! Can barely download in the store and loading a page takes a while.....and yes, I realize that its supposed to help with battery and whatnot but I don't like it and just want 4G back!!! lol
So far, I can only get 4g back when I unroot and do a hard factory reset...
And even then, it still shows h/H+ until I go through all the system updates.... then, I go to install another TW rom and I'm back with the h/h+ again...
I have tried the att fix, installing latest modem and still no luck.
I even asked to do a factory reset on my fathers phone (we are on the same family plan) and his shows 4g even when installing any TW rom...
Does anyone out there know what I did wrong?? also, my imei number is fine..
Thanks in advance to any advice or help

Yes apn checks out just and on LTE/GSM/WCDMA.

So it constantly switches between 3g, H, and H+ ? Have you downloaded a network signal app to see what kind of signal you are getting and strong it really is ?
When you say you have done a complete unroot and factory reset, what method are you using ? Is this where to flash an unrooted stock firmware from lets say Sam Mobile and then done a factory reset ? Or are you just doing another type of unroot ? When you root what method are you using ?
You stated you are on a Telus model but flashed an at&t modem ? Are you on AT&T service ?

Getting 5753kbps download and 905kbps upload .
Whereas before my kbps were always around 11-12000kbps for the download speeds.
I always flash back to stock rom using odin and then factory reset.
Oh sorry if I stated that wrong. I tried an att fix as well as flashing the most recent modem for my telus device but both fixes did nothing.
Again tho, ive done this so many times with TW roms and cant figure it out..
Im currently trying to go back to stock and use the most recent CWM to flash and see if that helps

It doesn't seem to make sense that even after going back to stock unrooted 4.0.4 (or what ever it cmae with from the factory) you still have signal problems as the odin packages would flash the correct modem once you install.

Sounds like network issues.

Speeds of ~9000kb are actually pretty standard for actual usage with H+/H/3G. Don't worry about speed too much. And for future reference 4G is H+, its just another name for it. The common misconception is that 4G is LTE which it is not.

Thank you for your reply.. yes I know what it means and its pretty cool. But again, my father and I are on the same plan, with telus with same phones. Going back to stock rom with odin still shows h/h+ when it should show 4g. I kniw they are the same, but the fast dormacy is a pain in the rear. My father and I are currently running the same rom with the same service getting 4g on his and h/h+ on mine

No kidding!! Ive done this a thousand times and have never seen it before..so starting to grt frustrated when told that its normal lol..
So when I get to 4.0.4 its still h/h+, but when I update the first time from samsung, it then shows 4g and my speeds are back to normal. But then as soon as I flash afyer rooting, it gies right back to h/h+ fast dormacy with no way of going back unless i do a hard factory reset again.

Are you sure it is the exact same version that you are running? He didn't update at all, no matter how small the update? If you flash from odin, everything that you did in the past should be overwritten. Go to settings->about phone and tell me what both of your baseband/build versions are

Btw.. I downloaded the whole odin/telus stock tar md5 and recovery about a year ago and have been using that for both of our phones. I will update in a coupke of hours
Also, when I flash back to stock and get the 4g back is there a way to save the modem and/or other files needed to bring over to another rom?
Ok so here is the image I took of my phone info..
I would have to put my fathers back to stock to see if there are the same... but Im now on 4.0.4 with h/h+ still present. Im gonna do a hard factory reset to get the 4G back and then see about trying other things.

general rule of thumb, touchwiz roms cannot be built from source. The only way to mess with these roms is with winzipping and adding apps (i call it bloatware) to be honest, if you want customization go to AOSP. Every single time I use a touchwiz rom no matter how smooth its says it is, I get crashes, bugs, irreversible issues like you have, loss of connectivity, the list goes on. Thats all because of the limitations of not having source code, I would recommend you drop the touchjizz and find an AOSP rom you like, if not, stock rom is the way to go.

I agree.. I'm under the impression its the other way around.

Hey just curious.. I was reading about going back to stock and making a copy of the qcn??
Can anyone confirm that copying this and then injecting it after a flash would work?

That your opinion is somehow fact. That somehow using a TW rom will just give you bugs and ruin your phone, as if a custom rom doesn't have glaring bugs as well. It's quite awesome the amount of customization that the dev's on the touchwiz rom's are able to inject into their rom's. Anyonr who thinks it's just unzipping files and adding apk's is uninformed. Is it on the level of PA or AOKP of course not but with more customization you add the possibility and almost the certainty that you have bugs and instability. We are quite spoiled on the i747 that we have kt and Task developing rock solid custom rom's. Most out there don't have that pleasure. If a TW rom on here is unstable it's because the dev has fallen short some where. I'd say I fall in this category and I am certainly no dev, just a noob cook. Equating TW rom's from 2.2 to the ones we have now is just fallacy. I do agree not having the source code put's dev's on the
In general I have had to deal with more bugs and instability with custom rom's than I have with a stock based rom (stock meaning what came on the phone). Yet that is not a gripe but merely the fact that I don't like to deal with the little things that pop up on custom rom's, and I prefer the aesthetics of TW. Crazy I know as many find it ugly.

[Q] Lost LTE after switching to KitKat

I decided to give Kit Kat another try a few days ago, but since then I have not been able to connect to LTE.
Prior to flashing I was running CM10.2 and my LTE was working fine. I initially lost LTE when I flashed PACMAN. I have also tried AOSB/ProBAM and Beanstalk. None of the Kit Kat roms gave me LTE so I gave up and restored CM10.2, but afterward I was still not getting any LTE connection.
I tried flashing the MD4 modem, but that didn't seem to fix anything. I've also heard that going back to stock could help, but I'd rather not have Knox if I don't have to use it. Which stock ROM here on XDA would be the best (Not planning on using the ROM. I just want LTE and then will flash back to Kit Kat)? Would a different modem fix my LTE issues? Is MK3 better than MD4, or are there any newer modems I should try?
Thanks for the help!

Any of the ROMS that have [TW] in the title should work. Full Knox only comes with flashing a tar file in ODIN, because your flashing every partition of the phone. Modified stock ROM zips do not have knox, unless otherwise noted. Make sure to do a prl and profile update when you flash to stock.

Flashed Wicked Sensations last night with the MK3 modem and I seemed to be getting LTE as soon as that booted. Updated my PRL and Profile, and then wiped. Installed AOSB again, and I seemed to be getting LTE until I rebooted. After the first reboot I seem to be stuck in 3G again.

Im currently running AOSB on 2 devices. When I first flashed them, I had the same issue until I rebooted the phone. After that I never had this issue again.

I think that's the opposite of what happened to me. My status bar said I had LTE when I first booted AOSB (this was after flashing/wiping TW). After the first reboot it connected to 3G and I haven't seen the LTE signal since.
I have updated the APNs, but I was using the same APNs for a while and had LTE on CM10.2 with them.

This is something wierd with Kitkat. I do not believe a fix has been found just yet. but if you dial *#*#info#*#* on most phones you can get into the phone systems and turn LTE back on.

I didn't know about this menu. Thanks for that. I went into Phone Info and tried selecting LTE only but it didn't connect to anything. Not sure what that means. There are other
There are some other options in there for networks (e.g. TD-SCDMA, CDMA auto). Would any of them help picking up Sprint LTE?
Other options include:
Turn off radio, CellInfoListRate
Turn on IMS registration required
Turn on SMS over IMS
Turn on lte ram dump
SMSC:_____________ Update Refresh

KitKat roms are currently having data issues. You could try backing up your current KK rom and go back to Stock, update prl and backup your DNS settings then go back to your backed up KK rom and restore from the dns settings you backed up.

How does one downgrade from kitkat to jellybean? I tried to just flash a jellybean ROM with a clean install and got an error?

It says something to do with missing a partition?

I decided to give Kit Kat another try a few days ago, but since then I have not been able to connect to LTE.
Prior to flashing I was running CM10.2 and my LTE was working fine. I initially lost LTE when I flashed PACMAN. I have also tried AOSB/ProBAM and Beanstalk. None of the Kit Kat roms gave me LTE so I gave up and restored CM10.2, but afterward I was still not getting any LTE connection.
I tried flashing the MD4 modem, but that didn't seem to fix anything. I've also heard that going back to stock could help, but I'd rather not have Knox if I don't have to use it. Which stock ROM here on XDA would be the best (Not planning on using the ROM. I just want LTE and then will flash back to Kit Kat)? Would a different modem fix my LTE issues? Is MK3 better than MD4, or are there any newer modems I should try?
Thanks for the help!

ohhh i had this issue but i figured it out for pacman and most roms just download nova launcher and when you do create a shortcut on nova ad click on setting an it should say apn once there u open it and youll see where it says ehprd something like that click on it and go all the way to the bottom and change where it says bearer to ehrpd and lte should work ^_^

Ok so I finally got it working, although I'm not sure what was wrong with everything in the first place. My buddy said Cyanogenmod screwed up a recent ROM, so maybe that code was in one of the ROMs I was using.
Each time I flashed back to TouchWiz (I ended up using Wicked Sensations) I could get 4G/LTE. I ran a **72786*, did a PRL & profile update. Prior to finding a working ROM, when I went back to BeanStalk/PACMAN I would lose LTE. After I found the updated BeanStalk ROM I flashed and it still had LTE! Happy days!
At this point I was able to send MMS somehow, but phone was having problems being recognized by the network. I could connect to LTE but couldn't use the data. After I updated the APNs everything started working again.
