If my problem is already exist in other thread, please link me to those thread. So, I think nobody have my experience. I'm still completely clueless, but will try to restore to very original condition tomorrow.
I got very weird issue. My phone not work normally today, as it get low signal for a day and that horrible, make me want to test DX modem speed and signal stability.
So, here it is
I already rooted my device, and flash new modem because I install new ROM. After many reading, I read that my original modem DXUBMF8 one is more stable than my modem atm, the XXUBMG9, so I want to test the network speed. I already test my XX modem, and the result is not that bad (for real, it's good anyway), so I'm about to test my original modem. I flashed the modem, and also custom ROM that support it, and, my phone got the signal but it can't connect to the network (the signal shows bar, but not show the H+ with the up & down arrow, or the 3G). Then I tried to restore the stock ROM that I backed up in the first day after I rooted it (it was normal that day), and same things, the signal bar is filled, but no network indicator (H+, H, or the 3G), then I flashed the stock ROM and unroot it with firmware from sammobile.com. Same things happened, the bar is filled, but no network indicator. So it's like my connection is locked in my ROM which people say it's not stable, and haven't try the connection of my original modem.
Anyone experienced or know how to fixed this things ?

Hi there,
after updating to official Froyo JPO/JPP/JP3 my radio doesn't work no more:
It shows signal after entering the SIM code
I can't make a call as it doesn't seem to connect to the network, although it shows network coverage.
I can't receive calls as well (tested with a landline).
The IMEI is still there and correct.
Product Code is I9000HKDDBT
Restoring old backups via Nandroid doesn't help
I wonder, what could be the reason. Reflashing different ROMs doesn't help (tried with JF3, JPO official, DocRom v8, ...). Supposing it could have something to do with /efs, I already restored my /efs folder to an earlier state, but it didn't work either. Could anyone tell me the correct permissions, owners and groups of the files within /efs? Or is it something totally different?
Thanks for your help!
Noone here that knows something about that?
I have the same problem i think. I can download apps from the market but can't recieve or make texts or calls.
can anyone help?
Same issue here.
Phone shows signal but if you show the status screen it only shows emergency call only.
Signal showing, according to the Debug it is showing 7 antenas nearby, also the network lock code is off for every lock, so i dont know...
is a Tmobile originally branded but flashed with darkys rom. PReviously was unlocked using the one click method,
does you phone display a baseband?
I had a jp3 in today that had no baseband
just flashed it using odin with jpy and it worked fine.
is a Tmobile originally branded but flashed with darkys rom. PReviously was unlocked using the one click method,
If it worked before that install then go back to the original works then you know where the problem is .

Me too, Flash the JPY or other firmware from uk orange firmware, has band and signal covered, but only emergency calls only at some places, specially at home.
hope someone can solve this problem
I'm new to flashing custom roms and what not. I used odin and flashed everything to the point, csc, modem,pda,pit the rom works awesome but i cannot for the life of me connect to the internet. the 3g icon or h icon wont' show up. in the status it says my network type is gprs and i'm roaming and my mobile network state is disconnected.
I'm with fido, the phone is unlocked i have never had trouble with data or anything until i flashed to a custom rom.
Anyone have the same problem or suggest how to fix?
Data Conn. Issue
Hey mate,
Have you gone into 'Settings', 'Wireless and Networks', 'Mobile Networks' and then 'APN settings' and entered your appropriate settings?
That should fix it if you define the correct access point.
Alex
hey man, yeah i did all that stuff, went in there, found my carrier, put in all the apn settings i can find and still nothing. when i put data roaming on then i get data and the edge icon comes up.
Hey dude,
That sounds strange, flashing custom (or even release) roms is never a guarantee especially with weaknesses in the way that ODIN communicates with your phone, What I would do is Re-Flash your stock rom through ODIN then use the "quick" install method from Darkyy.
I am running 5.6 like you, and I had issues doing it through odin (I kept getting random FC's), additionally, the rom; if installed from CWM will keep your apns and apps e.t.c. along with many settings and configs from the base rom you're using before the flash.
That is the best advice I can give you.
Alex
My config is a follows:
I9000 International
16gb SDHC
500HZ Hardcore Kernel
Darkyy 5.6
Whats the process for reverting back to stock 2.1 eclair rom?
Did you keep a record of your firmware version before reflashing?
If not, you may have to ask someone on here what your base firmware was.
Are you familiar with using ODIN? (The software used for reflashing)
Alex
I am having same issue to...I used 5.4 from Darky and it works well...same with DocRom 4.0 works and the next 5.1/6.0 don't work.
Both Darkys and DocRom are based some JPX....which seem to be root cause..
I've have the same problem. Tried eveything but still didn't work. So went to Samsung Service Centre to have my SGS firmware refresh. I notice after the refreshed same issue of data com missing. Told them and they when into the SGS to select the telco operator setting selection. Now data com. working well. Anyone know the SGS handset setting code? I want to reload to Darky's v5.6 again.
hi folks
i have the same problem... my provider is a virtual provider in the network of our biggest provider here in austria. i was using doc's rom based on xwjpa firmeware and everything worked fine without enabled roaming options.
since doc's rom is based on the newer releases (xxjpx, xxjpy) i' only able to use data connection if i turn on roaming. it also shows me that i'm in a roaming network. i guess the cause are the xx firmwares. xw and xx are european firmwares but i do not know the differences between them. maybe someone has more information about the differences? currently i'm using xwjpa firmware because i don't want to use my phone with enabled roaming options.
hey um i'm having the same problem and thought replying here would be better than starting a new thread.
well i installed the rom without having any idea of what i was doing *stupid idea* so i didn't take note of my original firmware.
i didn't use odin to install the rom just clockwork recovery and the rom and everything installed fine except my data network. i can get signal, call, receive the only problem is i get no data transfer. any help much appreciated. if anything can someone help me step by step to reboot my phone to original?
just for future travellers
Sadly this isn't my own gem, but yeah. hold the power button down, wait for the shutdown menu, above the airplane mode there is a data network button, and it'll most likely say "de-activated" if nothing else has worked. Its ok to feel like a chump, I did after rehashing the hell out of this phone for a few days ( the wifes phone, my phone does exactly what its told. )
Anyway, yeah, this will probably be the reason for the lack of the icon "G", "3G" or "H" where it should be.

Background:
- Sprint L720
- International unlocked with GSM SIM
After updating to a new 4.4 ROM (Slimkat) and NAE (modem only from the modem thread), connecting to anything other than EDGE causes, what seems to be, a modem crash. If I force "GSM only"/2G connection, it's stable with EDGE. If I try to connect to 3G, I see "3G" quickly flash on the status bar next to the signal indicator (I have full service), and then the whole mobile connecting drops and resets... then it goes back to having full service, but no data connection at all - until I got to mobile settings and set it back to "2G" and it goes back to stable EDGE.
I am overseas with the phone (it's fully unlocked and I got a strong H+ connection with the old CM ROMs at the same location), so I am wondering if it's an issue with the new 4.4 ROMs not supporting GSM? Perhaps some sort of baseband/modem mismatch? I also flashed NAE (modem only) as well when I did the ROM - I have since downgraded, but perhaps it isn't fully downgrading?
I applied the MF9 full one-click, no joy ... I did a factory wipe and applied the 4.2 factory image from SamMobile, no joy...
Looking at the logcat, I see something along the lines of an error for 'Mobile network type unknown: 0'...
Any help would be greatly appreciated - only having EDGE is driving me nuts, especially when my actual mobile network here is very fast..
Let me know of any information I need to provide - Thanks
Ok, update - I applied the MK2 modem and then NAE, as I saw someone else do because they said that the NAE file is missing some things... no joy
This all seems to have happened after applying the NAE modem-only file - Does SlimKat not support GSM? I don't think it's SlimKat, because, even going back to the fresh "Factory default" flash that I got some SamMobile, I still had the same issue..
Which leads me to what I think the problem is - the Qualcomm settings. Those seem to be persistent across all ROM restores, so how do I go about resetting the QUALCOMM settings to default? Is there something I can do with EFS Professional/CDMA Toolbox or something?
Hello,
I've noticed something strange this past month. I was getting data disconnections and I could'nt figure out why. Each time I look at my phone, turning the screen on, mobile network (voice + data) is missing for a few seconds, and comes back.
Now I know that if I keep the screen on for a while (I tried more thant 1 hour), I don't loose the network, but if let the screen go to sleep I immediately loose the network (I don't receive whatsapp messages in background), and when I turn the screen on, it comes back.
Weirdly, when my phone could reach 4G, I had (almost) no disconnection. It only happens in a 3G, edge, or nodata zone.
I changed my carrier (I just moved from europe to New Zealand), and it doen't change the problem.
I'm using CM11-Nightly (sept) on a I9505. I tried installing an old nightly(from july), and it was really full of error messages, so I switched back to a recent nightly, but in the meantime I had no disconnection.
Thank you for your help

I don't know exactly where this option is, but it's for battery saving. You can choose that somewhere in your settings I think
I think that's true for Wi-Fi, but I never found it for network.
And now it seems that network won't come back if I don't go to airplane mode and back to normal mode.
I'm having the same problem, seems to mostly affect lollipop installs.
Did you find a solution?

No I didn't. It seems that somewhere in july 2014, CM11 included a new version of the modem. So every CM11 build after that and every CM12 build is affected (I don't know about other roms).
I read that it was the way the modem handled finding the best network method. With the previous modem (v5 ?) it tried to get LTE, 3G, etc... but now it fails when it fails to get the prefered network.
4 solutions:
- flash the modem (didn't try it, don't know how)
- You're supposed to be able to choose you're prefered network in the options and choose 2G/edge. Didn't work for me but I'm interested in your feedback.
- get an old version of CM11
- live with it (my current option :'( )
There is maybe another solution, I'm not an expert, just a desperate user.
Hey again, I did fix it for myself.
The modem is the problem (I flashed my modem, and my bootloader just to be re-up-to-date).
If you want to get lollipop for yourself you should do it, its not too hard
Its listed as Qustion 14 on this here page: http://forum.xda-developers.com/showthread.php?t=2419762
I don't mind trying to give some pointers if you need help understanding how to do it, but I did this at 5am while sick so my memory of what I did is not 100%, never the less I would like to help if you need it.
Thank you for the advice (you came seeking for one, and ended up helping me ).
How did you choose which modem version to pick up ? the latest ? Do you have to do it after every CM upgrade ?
Edit:
I found the latest version from one of your links : http://forum.xda-developers.com/showthread.php?p=50965837#post50965837
Is the "Combined package - both modems in one flashable file." ok ?
And what does flashing the bootloader do ?
"What it does"... I am not 100%, I assume it initialize some part of the system, HW or kernel level, but I might be way off.
In any case I did use the dual modem pack to flash both "PHONE" and "PDA", another thread I asked in just replied to another user with the neccessity to flash the new bootloader aswell (dont know if the version numbers applies for you):
u must be using a 4.4.2 baseband and bootloader .. just a 4.4.2 baseband will not work .. once updated ur set

My question is on this page a bit down, and some replies a bit further down than that:

Tip: I had to save the PIT to a file (did it twice to be sure) with heimdall before using odin to flash (couldn't get heimdall to work for that part), all because odin would not play nice inbetween loading the PIT from device and flashing, this might not be a problem for you at all so it's just an FYI.
I managed to flash the modem & the bootloader. So far, no disconnection, so I'm quite happy.

Use the modem for your network as has been said before .
