GSM Problem after flashing ROM

Dear friends,
I have a Samsung Galaxy Note. I tried flashing several custom ROMs. Then I figured out that my GSM modem loses signal every now and then and I have to restart the phone every couple of minutes. (Going to flight mode and returning back also works).
I thought it relates to Custom ROM, so I get back to the stock ROM, but didn't solve the problem. I tried flashing different modems using Odin, but all of them are losing signal... So currently I can't use my phone
I live in Iran and tried the following modems:
XXLA1
XXLA3
XXLA4 (My friend's Galaxy Note official ROM uses this as base band)
Maybe I have to get back everything (include partitioning) to factory defaults from the scratch... But how?
FYI: My SIM works well on other phones.
Please help... :crying:

Check your efs folder. Search the forums.

In my case, GALAXSIMUNLOCK didn't work :crying:
Also I used EFS Pro to recover NV data and still no hope... I don't have any backup from my EFS folder.
Any other opinion?
How can I restore everything to factory data including EFS and all partitions? Could it work at all?

no way to restore efs to factory defaults if you don't have a backup of that time.

Is it possible to copy that from another Galaxy Note in the same network?

havent tried it... but the efs contains IMEI and some mac info ogf wifi and bluetooth.. may be these things will get affected of you do so,,

I don't have any IMEI problem, nor a network lock. When there is signal, everything works fine just as usual. There's even no disconnection during calls. But when I leave the phone alone, it loses signal after 5-10 minutes (sometimes more) and I have to restart or enable and disable flight mode.
Maybe it is not related to efs or network lock at all...

[[Update]]
I figured out that the problem only occurs in my apartment's neighborhood and both SIM and GNote 7000 work well anywhere else. But the problem raised just after I changed the ROM.
Could there be something wrong with the nearby BTS and Galaxy Note? My SIM works well in an old Nokia phone in the same area!

normally it should be fine if you flash the modem/radio on your own region.
when you said you have flashed so many modem file, is it from other region, or is it from your own region ?
Previously when I got problem with the signal / network provider, I will just flash back the modem of my own region. Everything works well.

[Q] Samsung Galaxy S i9000: No Data Network after updating to Jelly Bean 4.2.2

After updating my phone to the latest OS (Jelly Bean 4.2.2), everything was fine, but then all of a sudden I couldn't access the internet. I have tried several different APN settings and even flashed several other roms. I contacted my service provider (giffgaff) but they said there may be something wrong with my phone. I can send and receive calls and texts but just can't access the internet. I downloaded an app of Google Play which showed that my 'Data Activity' was either 'no activity or 'upload activity', however it still said that I was connected to my data. Can anyone offer any help or advice?

same happened to me i flashed darkyrom 10.2 re it seemed to work until i tried to connect to google play and i lost data and network changed from 3 to orange its doin my head in gona try a stock rom see if that helps if not it may be the sim card wife wouldnt let me try hers incase i wrecked hers also hahaha will let you know

I think that if u reflash it by 2.3.6 JVU firmweare will solve ur probléme and then u can update to 4.2.2. Good luck

No don't reflash lol
You just need to put in the APN information for your network manually in settings.

Try to switch airplane mode on and off, then check the APN's and maybe you need to add your APN but that depends on your provider. This always works for me.

the best reason why it happen because the ROM or FIRMWARE that you installed in your samsung galaxy s is not compatible some firmware and roms are only allowed in a specific country because it contains MODEM that makes your cellphone to have a signal on what country you are in OR the Samsung Galaxy S that you have is only for certain country only like my Samsung Galaxy S SC-02B which is NTTDocomo which has 2.2 froyo firmware when i upgrade it to higher firmware such like jellybean or icecream it successfully upgraded but you cant use the cellphone 100% since the signal will lost because your IMEI is fake or your IMEI is none. check your back of your samsung to check the right IMEI.
SOLUTION:
downgrade your phone back to its original firmware and rom make sure it is the original!
and you will see it will back to its default settings your signal is back so as your IMEI

what i did
1 flashed darkyrom 10.2re downloaded apn tweaker from market
2 flashed alliancerom jw4
3 then j w8
all working good

Did you try Settings -> More Settings -> Mobile networks -> Network mode, set it 4G only or auto connect.
Another workaround maybe there's problem with your apn's? For example I had it set to MMS then ahd EDGE available only.
Second warkaround is secret menu, type it in dialer *#0011#.

how to set up MMS then ahd EDGE available only?
and i typed ?*#0011# and its showing

I have exactly same problem with silver.. Have you fixed it? I have tried to fix problem some, but nothing looks like gonna fix it...
I have tried everything that was written on the forum..
When I check *#0011# it shows that only GSM900 is available...
Anybody?

Have you tried changing it to WCDMA. I was having that problem with the 3g service not going above a few kbs, I changed it from gsm to WCDMA nd its back to full speed 3mbs.

Where did you buy it?. Did you see if the modem frequency of the carrier it's available in your phone?, I got the same problem and it's possible that my phone doesn't have the hardware ready for the carrier in my country. I still looking for an answer.

Check your network before purchase as hardware is not flash able .

[Q] 4g problem i9305

Can somebody help me with this 4g problem?
This is what i did:
1.flashed custom ROM (worked like a charm,i did nandroid backup)
2.flashed other custom ROM (didnt like it so I restored the first one from nandroid)
3.everything went well except no imei and no baseband
4.reverted back to stock rom with odin
5.and here is the problem,no 4g signal at all. 3g/2g works fine.
If I post my build.prop can somebody tell me whats wrong?
I have tried to put my sim card in other phone and it works but not in my phone.

Did you enable 4G in Settings?
Sent from my GT-I9305 using XDA Free mobile app

Yes, I did...network mode is set to LTE
Is there a test that I can use to test is it a software or hardware issue?

Maybe an issue of Stock rom you flashed using odin.. Which one exactly have yoi flashed? What modem you have now? And finally, is your S3 i9305 or some i9305T variant?

Check this out:
Typ *#*#4636#*#* and goto Netinformation, then you will find a special-setup for the 2G 3G & 4G.
Sorry about my english. Cause i am german.

Thanks for your replies,I flashed stock german 4.4.4 from sammobile.It worked very good about 2 months.
I think that modem is xxufoa1 and version of phone is i9305 lte international.
If somebody could help me with this issue,I would appreciate that.But no hurries,I got new playmate S6 edge...

try doing a complete wipe of data and cache, then flash stock rom again to see if problem persists

I have tried many times but no help...

Hey, try flashing the parambin.zip file (look for it on google related to s3 lte, you'll find it easily). Another thing to try is just wait with the phone turned on with a valid SIM. I found out that sometimes it delayed a lot to get signal, specially when changing SIM carriers on another country. After a while waiting it finally succeeded (probably unrelated but I also saw on the catlog entries about upgrading the sahara file of the qualcomm chip -the modem-).

Stock Marshmallow Network Error 800-F

Hey Guys. I've a very big problem. i flashed again two weeks to my original s5 mini stockfirmware 5.1.1 the stock firmware (full package) of marshmallow. All works fine, i dont wiped data because all was working. last night the phone doesnt wont anymore to register into the provider network. ive rebooted the phone but it doesnt help.
steps i've tried:
- reflash marshmallow stock
- reflash modem with different version: https://forum.xda-developers.com/galaxy-s5-mini/general/baseband-sm-g800f-t3354355
- flashed cm13
- flashed lollipop back (but this have failed on flash via odin, so i flashed again the marshmallow).
- cleaned the sim slot (the sim card works fine on another phone, another sim doesnt works with the s5mini)
- checked the sim slot pins (adjusted them for perfect contact)
i dont think its a softwareproblem of marshmallow because it had run for two weeks very fine.
any ideas?
hope for help
greetings from austria

Have you tried setting it in 2G mode only, this is a very common problem with the S5 mini. It stop working in 3G and 4G , but everything ok in 2G ( but at the 2G speed )
