network question - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

i got a rooted s3 and i like to flash roms. i recently flashed dandroid but i went back to stock by odin. originally my icon is H+ but after i used stock firmware from sammobile ( i got an unlocked, non carrier version s3) the icon became 4g. i notice since then my speed has been worse because its really unstable, the signal doesnt drop but it never connects. I mean like those tiny arrows that tell you if theres any data moving dont do anything. Even using a lightweight browser like opera mini is slow now. Is there ny way to go back to before? btw i already tried reflashed and wiped data.

Have you tried a different modem?

Download, then flash in recovery, just like a ROM...

Stock rom shows 4GLTE no matter what you are getting. Go to the "about phone" and look for the current data type. For me it says LTE:13 or something to that extent.

A word of caution, cause it just happened to me. Be sure to backup you IMEI if you haven't done so and put it in a safe place, or two! I don't think you have this problem now. In settings-about your IMEI would be 0. I had a backup but freaking lost it somehow and had to get a new phone. I could not get data even though my arrows were moving as well, but it only showed E and G networks. The list of modems is in the Sticky and there is no better one. It depends on your area. Have you checked your APNs? Sometimes you have to enter or reenter them manually. There are tools to back them up. Its in the settings-more-mobile-access point names. The newest one i believe is titled phone. might say pta as well.

[Q] No service whatsoever

*Bad english ahead*
The problem is that my phone seems to refuse to get any service at all. The signal icon just shows a big "X" and it is stuck in "Searching for service".
Phone status shows that the Signal strenght is on -79 dBm, so i guess the anthena is working just fine. But below Service Sate it just shows "Out of service".
Im using a EB13 Modem with the SyndicateROM.
In fact, the phone was working just fine with MidnightROM until i flashed the SyndicateROM over.
Already tried reverting it to Stock rom and nothin, any suggestions?
Did you try reflashing (Just) the modem through ODIN?
Let me try...
Does this one should work? (The odin one)

Did you flash your Epic to Telcel? If so, that process might be causing you some problems. After using Odin to get back to stock, install CWM3 then SRF1.0.1, then once you're stable there, try the carrier flash again.

What do you mean by "Flashing my epic to telcel" and that "Carrier flash?" is on Iusacell, since Telcel dont support CDMA.
And one last thing, what is SFR1.0.1?
EDIT:
Im reverting back to DI18 Stock rom with odin to see if i can do something.

Oh okay - the banner under your username says Telcel, so I figured they were it. I thought I'd read they support CDMA but I was mistaken.
SRF1.0.1 is SyndicateROM Frozen 1.0.1.
On the flash, let me rephrase - did you do anything special to get the Epic to work on Iusacell, or did it work there out of the box?
That's the reason then. You can't change ROMs if you're on a carrier other than Sprint, it will revert your phone back to Sprint.

Nope, the phone was working just fine out of the box. It had signal (Roaming) and all.
I even flashed like 3 roms before Syndicate and it was working just fine. Was just yesterday that i decided to try this ROM out and got the problem.

I'm not entirely sure what to tell you - there's nothing in SRF that should/will/can cause any problems of that sort. Going back to full stock via Odin didn't help?
I followed this guide: http://forum.xda-developers.com/wiki/index.php?title=Samsung_Galaxy_S/SPH-D700 to return to Stock rom, but i can't get this thing working
Im pretty much lost as well.
EDIT:
Oh god what the... I was just messing around with the phone. Turned on the Flight mode. Made a Factory reset via Privacy setting, Rebooted the phone, turned off the a Flight mode and suddenly had signal again.
I dont know what happened, since i tried the factory reset before with no luck... But well, im glad its working now. Thank you to both of you for the help anyways.
I have a similar problem as the OP, and I'm pretty sure it's ClockworkMod that's causing it.
Seems like every other time I do something in CWM, I get no service and an unknown Baseband and Hardware version in the phone's settings.
So far the only reliable way I've found of fixing it is to Odin all the way back to DI18 and start fresh.
For some reason Odining the modem or EB13 doesn't work (I still get no service).
And I must say, it's incredibly frustrating.
I guess I'll just have to get SRF flashed and never touch CWM again (because doing so almost always breaks my phone).
I'd like to be able to make Nandroid backups though, but unfortunately, doing so breaks the modem (which really doesn't make any sense).

Impossible to get network operator

I flashed CM10.1 on my S3 and had the same problem as others where data was intermittent. It worked for some time and after one nightly, I lost my IMEI. So I got back to stock, used the procedure with QPST and got back my IMEI. I got back to cm10.1 and unsurprisingly, I had a hard time having data. But worst off, I had a hard time having cell connection anymore, not even voice or sms. Tried AOKP without any luck. Tried different modems, not luck either. Now I went back to stock and still doesn't work. There's something that is not resetted between flash of ROM that keeps messing up my connection. I also found out that only one network provider is ever found, one is Rogers Wireless (I'm with Bell), or one is EXT. But never any other provider is ever found. And also in *#*#4636#*#* under phone info I can'T change the radio band like I can on the phone of my girlfriend.
So there it is. I'm stuck. I don't really want to buy another phone. It is a software issue for sure. But how can we solve that? Is there any way to restore the EFS to factory default? Could it be buried there? What is the ERI? Could it be that? My stock ROm says that it can't get the ERI version.
Any help is welcome.
my stock telus ERI is unavailable but i think thats normal... i have no problems
from what i understand imei and apn settings are the things to check into

IMEI and APN are good. IMEI will get me data, but I can't even get a cell connection now. No radio at all.
whats your radio band set to?
if i set mine to anything but automatic it wont find networks like yours..
*#*#4636#*#* dont work on my telus s3.
i use a different method
*#197328460# then
UMTS > Debug Screen > Phone control > Network Control > Band selection >
Automatic...
beware what you change in here as there is no return to default

Neither of the two works. *#*#4636#*#* was working with CM10/10.1 and AOKP. But not with stock. And the one you suggest after is not working either.
But I remember going ot *#*#4636#*#* before flashing stock rom and I wasn't able to selet any band. On my girlfriend's android phone (HTC) I can.
if it were me.. i would try reflashing stock again... after flashing stock do a factory reset thru recovery... seems to help for clean stock setup.
if still no network i would check that band selection is set to automatic.
maybe someone else with more experience would have a better idea.
you mentioned you changed your band selection and now cant change it back.
i dont think flashing stock changes this.
i think that might be your problem.
ifso you first need to fix phone to use *# code... i have no idea why its not working
it works on my stock telus 4.0.4 and 4.1.1
maybe bell blocks from using *#code?

if i were u i would first try your girls sim in your phone and vise versa and if no luck do the qpst instructions to regain LTE not imei .and if u still cant manually find network operator after that i would format both sd cards and odin back to stock rooted and do the imei injection again for the hell of it and the LTE fix ..and stay on stock rooted or 4.1.2 until u get this figured out cause 4.2 builds are gonna have more probs then 4.1...I know u are having cell connect probs and these instructions are for imei and data but it sounds like your out of options....i lost imei once and had to manually inject with qpst and my reception was one bar til i did the LTE fix and it worked awesome..one more thing is my phone will not select a radio band ever unless i manually select my network operator first or i have no sim card in phone..i have also had sim cards crap out for no apparent reason..good luck

Thanks for your answer. Really appreciated. I've flashed so much time that I don't see the point of doing it again. I also had, at some point, to inject my IMEI and it worked with QPST.
What I find really strange is that a stock reflash doesn't put everything back to when I bought the phone. Funny thing, after the flash, it knew what my Wi-Fi router password was! So obviously there are some part of the config that is not overwritten. Which I find odd.
I also started playing with the service menu and found a lot of settings for the radio band. No luck yet.

Your WiFi password could have been restored by google just like it puts your contact info back.
If you are doing a Odin to stock that should wipe it clean.

This thing is so strange. There's only one network that my phone can see now, and it is 302720. Bell is 302610. No other network is visible. And since I'm with Bell, then I can't connect to 302720. I'm in for emergency calls only. That's why I thought it may have to do with radio. But it seems Rogers (302720) and Bell use the same bands. A channel maybe? But this should be all automatic! It's a pretty stupid bug let me tell you!
Maybe a SIM card issue? That would be quite a coincidence that it happen exactly when I'm playing with ROMs...

Ah that's a good possibility. I didn't know it was saving passwords as well.
So if it wipes clean, how come this bug stays? There is obviously something that is not wiped and overwritten or else it would work.
How can one tell if someone losses their IMEI number? Unable to make phone calls? No 4g/ lte?

When you go to info about your phone, in status you usually have your IMEI number. It'll show 0 if it's corrupted. Or sometimes it's a generic IMEI dans is used when the real one is unknown. It's 049 something I think.
Without an IMEI number you can do phone call. But you'll never have a data connection.

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.

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

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

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

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.

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

Ok so the baseband is I747MVLDLK4 and build version is 2.4? lol
I will unroot and flash back to 4.0.4 with a factory reset and then update this post.
Really appreciate ur help
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.

Yes, this I understand... but with the 4G displaying, I get NO fast dormancy causing download issues and on top of that, my download speeds are 11-12000kbps.. when showing h/h+, Im getting half the speeds and constant toggling from 3g/h/h+ is driving me up the wall!!
again, Ive never seen this on my Telus TW roms..
I will be unrooting and going back to stock with odin...then doing a factory reset..it will still show the h/h+ unless I do 1 of 2 things....either do a hard factory reset using *2767*3855#, or by simply doing a Samsung update...then after one of those, 4G will be back and so will my speeds.

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.

Radio issues with 4.2 Roms

Hi all, I am again posting about having radio issues. (NO T-Mobile signal) Any 4.2 Rom I try to install, I am unable to obtain phone service. (signal)
Here is what I did:
1. Start from scratch, total erased phone and sd card and micro card.
2. Odin flash stock Rom and Odin flash latest TWRP
3. Copy Rom to SD card and flash. (flash is fine)
4. No signal, flashed newest UVM6 radio, all kind of wipes.
My phone is SGH-T989 T-Mobile. I even changed the APN, but still only pick up AT&T which still having no signal bars. I tried flashing all radios available with no help at all. I am able to use certain 4.1.2 Roms such as Infamous 3. I even tried different kernels, different wipes and just can not get any T-Mobile signal service. I have tried searching for any and all radio issues for this phone. NOTHING works for me. Can anyone or does anyone have same problem that came up with a solution to get a signal for T-Mobile for these Roms? I am currently using the Infamous 3 Rom using Arc kernel. Actually the only other Rom I can use it the stock deodexed rooted base. Very frustrated not being able to use these great looking Roms, HELP please! Thanks for any information or solution. BTW, I have tried everthing and every type of wipe to no avail.
do you still have your IMEI or does it shows blank and unknown ??
I am having the same issue. It does show my imei # though. How do I fix this?

Oh boy.....again.
K....here is about everything. If none of this is your problem, since you say you've checked everything....and yes, I have read your other thread....in which you repeatedly say you tried everything, then you have a hardware issue, or are simply doing something wrong and telling us you did it right.
Not getting a signal.....
- not using latest T-Mobile or Telus radio. Maybe you flashed it, but is it actually showing as that radio in settings??
- APN settings are wrong or don't exist. Lets pause here. You said you checked apn and only pick up at&t. Or am I misreading that. If you don't have the correct T-Mobile apn settings, then you wont get a signal or data. Period. This has to be correct before bothering with anything else. You said you checked. Against what?? I've seen plenty of apn settings when Googling it, some simply don't work. Maybe they are old settings, wrong phone, whatever. I'm Telus, so can't help you with the settings for T-Mobile.
- what has already been posted above needs to be correct.
- maybe radio file you flashed was wrong one or corrupt. Perhaps try the Telus one. Should work too. Since T-Mobile radio works on Telus.
- restoring any system data after a flash? Huge no no.
- wrong mobile band selected?
- and a possibility .....simply no signal where you are. Or it's a weak signal, and your assuming it doesn't work?? Ignore this if you have a very strong signal usually where you live. 4.1.2 to 4.2.2 shouldn't affect signal much if any.
Anyway.....that's about all there is to it if you are CLEAN flashing roms and following instructions to the letter. I am confident you will say all the above is good....and if so....I am afraid you will probably find no answers like your other thread. Meaning you have an extremely rare issue. Or a wierd hardware issue, sim card maybe....tho before you dismissed that as a cause. Another possibility is that you aren't correct when you say apn is fine, or the radio you flashed is fine. Not accusing you of misleading anyone, just saying perhaps you are innocently wrong when you tell us this or that is fine when it is not.. I've done tech support.....happens all the time! !!
So, good luck. Hope you find a solution ......tho this is your second thread on same issue....so you may have some rare issue....and may be boned.

I have been dealing with this problem for weeks, and I can almost guarantee you don't have the radio right and that's the problem. http://forum.xda-developers.com/showthread.php?t=2385987.
Here is the link to a radio I just flashed literally 5 minutes ago and started running 4.2 roms after weeks of struggle and frustration.

That would certainly make sense!
He's got something wrong for sure. Or he's got a strange phone that won't work with 4.2. And I doubt that very much.
He's got wrong radio, or wrong or missing APN settings.
Or wrong phone, sim or carrier.

Thanks for helping and I think your right about being boned or hardware issue. I have tried different downloads of radios, both Telius and Tmobile and copied APN settings from working stock Rom. Maybe bad Sim, anyway I will have to stay with what I have until I get new phone, which is soon. Thanks again!
Stumbled across this. I've never heard of this particular issue before, but sure sounds the same as your issue. Try this fix if you haven't already.
Everything below is copied from another thread......
i had this problem with slim too. i thought something went wrong with my phone or my area. but nope. what you need to do is go to mikeyman777 cm10.1 thread and find the uvmc6 tar file, then use odin to flash it. apparently just flashing the newest radio with twrp isn't enough because it's missing some files or something like that lol.
anyways i haven't had signal problems since flashing radio tar file. i've lost signal like once. before i was losing it everyday. hope this helps.
