No 3G after flashing, only EDGE

Hi !!
Looking in the forums, i have seen this problem in other models
The solution, normally, is to reset the APN settings to default (haven't worked for me)
flashed to stock firmware ... still with EDGE
Someone have experienced the same problem ?

Try a factory reset

u flashed back to stockrom using odin?
i have no idea bout this problem
but if you flashed stockrom using odin and did hard reset should fix the problem.
make sure its not about a network trouble from the provider

you might try this...open setting>wireless and network>mobile network. untick use packet data. network mode, choose wcdma only. tick use packet data.

This is what i've done
1- Flashed to an Indian firmware version, no backup (my mistake). From that
moment, losed 3G/H connectivity
2- Flashed various firmwares, no success
3- Thanks to Doky, i was able to get the original firmware of my phone, installed it and change the country via *#272*_your_imei_# and reboot
4- Still with EDGE ....
In a previous flash, i used the "WCDMA Only", but i lost my mobile network .
Going to test in another phone to see if it's a provider problem .....
Thanks for your help ...

when i used "WCDMA Only", my current network changed (i'm from Colombia, my SIM is movistar, changing the setting changed the current network to Tigo) ....

based on your explanation, it seems that you have bad signal reception dude...

Try some other South American modem from the OP in my topic!
Flash only the Phone/Modem part of S5360L and S5360B packs!

There's something special with that version ? ... i'm trying to not flash my phone unless the firmware has any sort of light to solve my problem (avoiding factory reset ... my phone must be dizzy ... so many resets ... )

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
edit. my bad i thought your girl also had gs3..maybe the sims are still the same

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.

[Q] Insert Sim to Access Network Service.. IMEI Null

Hey Guys,
I have an AT&T Model SGH-1317 Note 2. For use on other networks, I unlocked the phone using the *#197328640# menu option. However, the phone failed to start the hot spot stating Mobile data was unavailable or Invalid Sim. However, I am able to tether perfectly using the same sim on an another S3 so I was sure its nothing to do with the sim or network operator settings.
I looked up and found XDA website with tons of information. I assumed my phone was locked by AT&T. Hence, I rooted the phone using CF-Auto-Root, backed up complete data using Titanium and using Rom Manager I installed the Crash Aroma 4.1.2 Rom. I wiped the data and cache 3 times as suggested. However, after the boot I am unable to connect to any mobile network. A Click on Mobile Network says "Insert Sim Card to Access Network Services". Dialling for IMEI number prompt a Null.
During Installation I noticed the Crash ROM has overwritten the Radio.. and I am assuming this is were the problem lies. but I leave it you experts.. Request Help!
Sunil.

Am currently on Du - A network in Dubai, UAE. I have been reading more forum information and some suggest that this may be related to the EFS folder getting corrupted which may cause the IMEI number to fail. Some suggest that there are software to rebuild this information by using the IMEI number behind the handset..
I also noted that my phone model has also changed to GT-7100 instead of SGH-1317, Wonder if the Crash ROM was apt?
Would you suggest installing a Jedi Rom specifically built for SGH-1317... or is the damage already done?

Back Online
Since I found no replies.. I had no choice but to give it to the Pros.. I handed my phone day to one of the Unlocking experts at a mobile store… He was confident that his technicians would resolve this. But after 2 Days, they have given up.. He suggested the phone would fetch me US$ 10 if someone used it as a demo unit at a mobile shop..
I was sure this was something to do with the Modem, IMEI and the all important NV folder. I was able to find a Stock ROM for the SGH-1317 and I also found a link at XDA about using EFS pro to change the IMEI.
Using Odin software, I flashed the phone with the stock rom. Unfortunately, there was one error when it tried to communicated on com1. Having no choice, I continued. Restarting got the AT&T style boot but it again froze on the Samsung screen. Dreading the communication error, I restarted several times with no results. Finally I realised if would be due to the cache and user data. I reset the phone to factor settings wiping out the user data and Whola.. The phone sprang back up..
Lessons learnt.. Backup your rom and data before playing with custom roms. Read Read Read and don’t flash in the middle of the night..
Since I am back online, I plan to stick to the stock and crappy 4.1.1 with all the AT&T dead weight. Will live without the ability to Tether until my fingers get warmer.. It won’t be long as I am already bit by the Custom Rom Devil..
Don't Give Up Easy..:good::victory:

Please I am having the very exact same issue and can't seem to have it fixed
Using CMW I also flashed it back to stock rom, didnt have any problem or errors doing it but im still getting No SIM Inserted. I have deleted cache and user data several times... Tried flashing CM10 and CrashRom see if they made a difference and still No Sim Inserted... tried 3 different kernels and still same issue

I have the exact same problem since yesterday. I've tried everything and anything to no avail. I'm very close to returning the phone.
I would really appreciate any input.

Same issue
I flashed crash rom 4.5, over the stock kernel and it gave me that same message. I've tried everything I could think of, which included everything in this thread to no avail... any further advice would be greatly appreciated.

Your username suggests that you have the N7100 device ??
If so. ..you are in the wrong place for support. ..As this is the SGH-I317 section.
If you are showing IMEI NULL with no baseband you may have to restore your backup image to correct the problem. .
If no backup image exists. ..you will need to flash a factory N7100 image from your section.
Look for the return to stock thread for your specific device and that should fix you up...
The CF AUTO ROOT files are device specific. ..so I hope you haven't damaged the partitions.
Good luck. ..g
Edit:
This will help. ..and will place you in the right section. ..
Just go to page 1...good

[Q] Network Unavailable After Flashing New Rom

I have a Note ii n7100
I flashed to Paranoid Android earlier in the year and thought I'd try out something else for fun again this morning.
I first went to monxdified (monxDIFIED-N7100-XXDME1-13-01.zip) and there was cell signal but I couldn't get onto a cell network (I'm a three UK customer). It would say registered on network but would never actually register.
I then tried selecting a different radio in the installer, the top one, rather than the 2nd one - I was guessing that this was the issue. Same problem.
I then tried going to cyanogen (what I saw as a more trusted/well known rom to try that out) - this time it finds the network but says there is no signal and that (3UK) is unavailable.
I've been reading and I may have wiped my imei number, at this point I got scarred and thought I'd check here before messing this up any further.
I hope I've put this thread in the correct place. Thanks in advance.
Note: I can still read a value for my imdi number in settings, hopefully this means it isn't lost?

I've gone right back to defaults now with odin and am beginning to think it's an issue with my SIM.
Just closing this thread.

Don't forget to take your EFS backup.
Maybe you will live that problem again.

no it is not a SIM problem, i have the same problem, i did a backup for the previous rom but there is no network signal at all.
it would be great if anybody will help.

I didn't take an EFS Backup, the last time flashed a new ROM (Paranoid Android) I didn't need to. I assumed this would be the same story.

To what version, which file and how? Like I mentioned in my last post, I've gone back to absolute factory settings and now my phone counts as unrooted. I'm thinking of just sending it to samsung. I assume they'll fix the issue if I pay them?

After looking into the issue some more it seems my IMEI has been wiped. Not sure if there's anyway out of that one...

[Q] (RESOLVED) Slow 3G since installing Cyanogenmod

Hello,
I've just got a Nexus from my father.
Unlock and rooting are OK.
I've made a backup of my stock rom
Then I've installed a cynogenmod 4.4 and see that my 3G download speed is very slow (arround 5Ko/s)
Then I've returned back to my stock rom -> same issue.
I'm in France using Free Mobile (which is using roaming)
Please help me!
EDIT: RESOLVED
I've tryed a new SIM Card and the speed is OK.
Next I used my old sim card, the speed is OK too.
Strange...

I really need help because I am unable to get a good 3G connection.
Have reinstalled the last radio -> nothing
Have reconfigured APN -> nothing better

Really need help, take 1h to dl 20Mo
EDIt: The signal is full

Someone could help me ?

I've found that the issue happens only when I'm in roaming.
If I am connected directly to my provider antenna, no issue.

Its probably just an issue with your operator, the ROM most likely doesn't have to do anything with it, especially as you said if you flashed the stock radio.

Sorry but no, like I said, it worked before the flash, and now, it is not working anymore.
In same time, it works really well with my 2nd phone, with the same sim card.
