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.

Hi guys been searching all day when I can grab some free WiFi, basically I rooted my s4 gti9505 with auto root and then installed custom recovery, and flashed PAC rom. I'm unable to make calls or receive mobile data but can use WiFi. My settings say baseband unknown .. I'll attach a picture of my settings here in this thread. I have attempted to flash a modem/radio in Odin but this didn't seem to make any difference, the problem is I'm not sure if it was the right thing to do (didn't make a back up of my phone foolishly before flashing PAC rom)
I'd appreciate any help with this guys! My network is vodaphone UK if that makes any difference to any advice given...
Thanks in advance!

will do this too, have just finished flashing MGA modem twice using your steps, will flash rom again..i wonder if i should wipe/factory wipe as i would when installing new rom...ill try it!
no luck -still no network. im running out of ideas
network - unknown
mobile network type - unknown
imei unknown
imei sv - unknown
going out now for a while but thought id ask - do you think that installing official stock rom (perhaps from your s4 unrooting guide) would help flashed via odin? from searching i can see that some folk suggest that stock will reinstall everything i need...im hoping so, i really wouldnt mind going back to stock, anythings better than this

did you put modem in "phone" in odin?
hmmm weird! i guess your imei is not corrupted, sometimes while flashing rom in cwm, efs partition is not detected, so flashing modem twice should work
you can try with an other modem, use new one (but im sure to flash it twice)
another option is trying to flash your stock firmware

yes put it in "phone" mode, thats the second or third one i have flashed now so im not sure it wont help but for sure ill try again!
are you able to determine that its not corrupted? would it state as such if it were? im going to flash a stock firmware as a last resort. lost after that haha
edit - installed cwm using sgs4 flasher and re-installed my custom rom and gapps, booted no probs and network now working - sorted!! thanks for your help i dont think i would have reflashed the rom without your advice to do so
So I'm practically in the same boat. I'm currently on P.A.C. man nightly 09/18 (Vodafone Germany branded device). I never had similar problems, but now I can't call (or be called) and I'm not able to use mobile data.
I nearly tried everything:
1) I checked the IMEI (saved it before switching over to custom roms), but an IMEI number is still there.
2) Went back to stock to see if it's a problem of P.A.C. man ROMS or not. On stock it didn't work either.
3) Went back to P.A.C. man ROM and flashed modem XXUBMF8 via Odin 3.04 (from this thread: http://forum.xda-developers.com/showthread.php?t=2192025)
4) Flashed the modem again after I flashed the ROM because it didn't work either.
So I'm completely lost now, I really don't know what to do next. I had mobile data for a couple of seconds every now and then, but nothing stable. And since the problem came up (yesterday evening) I can not make any calls at all.
Can someone help me?
Edit: The very strange thing is that I have full reception balks in the notification area (only in grey). But still, I guess this means that the device is somehow able to detect a signal but can not connect to it?
Edit2: I apparently have no Device-ID. May that be a problem?
So I took some screenshots to show you guys my problem a bit better. For some reason my mobile data now works (currently HSPA, but it's extremely slow). But I still can't make any calls (or get called too). =/
Edit: So to sum this up: the strangest thing about this problem is, that even when I go back to full stock I can't make calls. =/ What could be the problem? An IMEI number is present in the settings (althouh the 'IMEI SV' under 'About phone' --> 'Status' was one digit below the current one that I can see under those stats). The whole problem makes me believe that my provider can't sort my phone number to my device (I'm on Vodafone; but if that's really the case: why the hell does mobile data works sometimes?!). The other possibility: something with the modem/radio is broken. Could this be the problem? The thing is that I also tried to flash a custom modem, but the problem is still there...
I'm really concerned that my phone just became an expensive paperweight
Slightly different than my problem in that I didn't even have any bars for reception..my problem was fixed by changing the custom recovery software (originally I used philz to flash PAC), But I flashed cwm and then used this to again flash PAC, and all was good..don't ask my why but it helped me so you might want to try this...

Thank you for your answer!
You also flashed a different modem didn't you? Did this help or was it only the custom recovery? I'm confused because I used CWM before and never had problems. But then this mess all came up...
Yes I flashed several modems, that didn't help..only using a different custom recovery to flash my custom Rom again helped..hope you get sorted!

So I tried to flash PAC with TWRP 2.6.0 (it worked before), but the problem is still there.
I'm really confused. I really don't know what I can do or try to fix this mess... Is there some USSD code or something to find out if my device is missing some ID codes or if the modem is messed up or something?
Edit:
Update: For some reason I now can receive calls/SMS but only when I'm on GPRS speed. Outgoing and ingoing calls are no problem then. When my device is on HSPA or HSPA+ speed however, the old problem of not being able to call or be called is back. On one hand it's good that I'm somehow able to make calls again on the other hand it gets stranger and stranger. I know that it's a bug on PAC man ROMs that you can't change the mobile data speed options (LTE/HSPA/GPRS etc.), but I think that this could be the problem (or at least a part of it)...

Actually I can change the data in my phone between 3G and 2G (don't have LTE support here in my country)
Have you checked your APN? Think that might be a problem.
Also please post the steps you take before flashing PAC (ROM, kernel, recovery, etc)

Within Wireless & Networks --> Mobile Networks --> Network Mode? On PAC? It always crashes when I try to change something there. In the PAC bug post this seems to be a known bug, my mode is also set to GSM/WCDMA/LTE. But whenever I enter the settings to change this, only 'LTE' is chosen as option. I don't have LTE on my plan and I read somewhere else that Vodafone has major problems with it's LTE network here in Germany and that it may be better for customers without it to turn it off.
About APN: there is definitely something strange. I can enter the settings and I see three different APNs that were not created by me (they must be the standard carrier ones): they are called Vodafone DE (for Germany), 1und1 (pretty strange because the settings are the very same on this one, only the name is different) and Vodafone DE-MMS.
The strange thing now is that I can't change any value of the Vodafone DE APN... When I go into its settings, everything ia greyed out. This was the same on the stock ROM...
Now when I create a new APN with the correct provider settings (found via Google on the VF homepage), the phone still won't work. When I put the device aside for a few minutes, the Vodafone Deutschland DE APN is the selected APN again although I never went back to it...
Is there some option to take a deeper look into the modem stats to see what's the problem?
Install stock ROM

I tried that already, but it didn't help. Same problem...
I factory resetted the phone, wiped cache and dalvik cache and then flashed my Vodafone branded stock ROM via Odin that I had on my device when I got it. Didn't help for some reason... But: should I also try to go back to stock ROM via KIES? I haven't tried this method until now...
Edit: About my flashing method: I went from the stock ROM to rooted (via CF Auto root with Odin). For PAC I then flashed TWRP 2.6.0 and then in recovery factory resetted the phone, wiped cache and dalvik and then installed PAC. After that I installed GApps. I used this method before and it worked without any problems...
Edit2: I found this thread, it appears to be the same/a similar problem with the S3: http://forum.xda-developers.com/showthread.php?t=1805709&page=6
Now is there something similar for the S4? I think I tried calling ##72786# on stock ROM and it didn't work...

Delete the unused APNs.
Do you have mobile data?
Also I asume that you're running the latest vertigo's build, because with me GSM/WCDMA/LTE is always selected.

Sometimes I have mobile data, but only for very limited time; for the majority of time, I don't have mobile data and can not make calls.
I also tried to delete the unused APNs, but still no change =/
I tried to use a different Micro SIM in this device, but the same problem appears. No data, no phone although I have grey reception balks.
any update on this one?!
Recently flashed Wicked v. 9.1 onto the stock slot using safestrap recovery, so far the rom has been working fine, and I've set up the apn. When looking at device info it shows I am connected to AT&T and LTE, but my mobile network state is disconnected. Any solutions for this?

Check to see if you still have the same modem as you started with.... I flashed a rom, I had connection but would cut out now and again... ended up relashing the same modem that was on the phone before... (modem did not change) now I have data and solid connection for phone calls.

Google the kind of phone you have and ATT is your provider I take it? Include which version of android also so something like..... i337 modem att android 4.3 of course swtich the proper name and provider that you have. You don't want to be flashing the wrong modem you could end up with a paper weight....
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.

Hi Guys,
I am writing this Thread believing that I will get a solution as Yota company has not provided any solution after 15 days trouble shooting. I just brought the phone from Russian seller through eBay.com to India and after 2 months of fight from the local customs office I just got my phone. I was very happy and was floating in air to have the first dual screen phone in my hand. The phone was flawless with dual screen was working awesome. The phone came with lollipop update. I switched on the phone with out inserting the simcard, the phone prompted for a small 350 MB update and I just update the phone. Then I just inserted the Simcard after which i started facing issue. The issue was the phone is able to read and shoe the service provider name but there was no network signal and it was showing only emergency calls. When i tried to make calls it showed network no registered. I tried with different simcard which resulted in the same issue. I though it might be a simcard issue and checked with my old phone but there was no simcard issue. So i just contacted the Yota tech team through mail to help me on this issue. They asked me do some basic troubleshooting but there was no use after 15 days they asked me to ship the phone to nearest service center which is in Russia. The issue is to and back from Russia customs will cost me the price of 2 Yotaphone fist generation phone price. So I through of resolving this issue myself and researched in online. I found that Samsung phones were also facing the same issue after update and tried all the solutions given in internet but there was no use. Finally there was a solution asking to root the phone and install the ariza patch which would solve the issue. I just rooted my phone and when I installed the ariza it showed it was not compilable for yotaphone 2. I just searched in XDA forums and could not find anyone reporting the similar issue with a solution. So I through of creating new thread in hope of getting a solution in this issue. Please help me in this issue by creating a patch or any solution which will me help me out of this. I am not able to use the phone as the basic call function is not even working reset the phone is a heaven.:crying::crying::crying:

They asked me do some basic troubleshooting but there was no use after 15 days they asked me to ship the phone to nearest service center which is in Russia. The issue is to and back from Russia customs will cost me the price of 2 Yotaphone fist generation phone price. So I through of resolving this issue myself and researched in online. I found that Samsung phones were also facing the same issue after update and tried all the solutions given in internet but there was no use. Finally there was a solution asking to root the phone and install the ariza patch which would solve the issue. I just rooted my phone and when I installed the ariza it showed it was not compilable for yotaphone 2. I just searched in XDA forums and could not find anyone reporting the similar issue with a solution. So I through of creating new thread in hope of getting a solution in this issue. Please help me in this issue by creating a patch or any solution which will me help me out of this. I am not able to use the phone as the basic call function is not even working reset the phone is a heaven.:crying::crying::crying:

Do you still have this problem?
I wasn't sure at first, I thought it was my sim card, but I have tried 2 different networks sims and they both get no signal in my Yotaphone 2...
The network's name does appear, so the sim must be being read somewhat, but I always get no signal.
I literally have no idea what to do.
I too turned the phone on without a simcard, flashed the RU latest rom, flashed TWRP, rooted it etc, surely that has nothing to do with it...?
@bharath9962 ! I fixed it!
I have no idea why this happened, and I spent a few hours trying to fix it, very angry. I downgraded to 4.4 to see if it would help, put back the native China rom that came with my phone (accidentally deleted my backup too...)
I bought a new sim card just for this phone because the old one did not 'work'.
This is not a popular phone so it's hard to find information, anyway... I'm very relieved now. I can only imagine you gave up...
I found the answer here - thewichitacomputerguy.com/blog/how-i-fixed-your-sim-card-does-not-allow-connection-network-g1
1. Open the phone dialer
2. Enter: *#*#4636#*#* (Once entered, you will be taken directly to a "Testing" page) [4636 spells INFO]
3. Tap Phone Information
4. Scroll to the bottom of the screen and you should see a button that says radio off. Hit this button and when it reads radio on Hit it again to turn the radio back on. <-- (Not a Typo)
I rebooted and waited a few seconds, no signal. I turned on airplane mode, turned it off, and it worked!
Now I can go back to RU 1.99 and reinstall all my stuff...

My country is in Asia but I believe this does not matter - the problem was that somehow the radio (cell phone function) was 'off'/glitched, and had to be turned on+off to make the phone function again. Using a different country's sim card would not fix this problem.
As I wrote above, we both share the fact that we first turned our phones on with no sim, and updated. Maybe just a coincidence...
Just try the guide and please let me know if it is fixed!

Fix for Yotaphone 2 YD206 from China
If you already flashed the phone to latest EU 5.0, you can skip 1-5
1. download via FTP: fw.ydevices.com/YotaPhone2/YotaPhoneFlasher/yotaphone2_flasher.exe and install
2. run flasher and download latest EU rom (2 - 5- 7)
3. turn off the phone and turn it on while holding volume down - this will boot the phone in "downloading..." mode
4. in the flasher press 1 (Flash the cellphone)
5. the phone is now on 5.0.0-EU1.1.124b and 2G is not working at all and 3G is connecting only to 2100 MHz (on my cell network)
6. download via FTP: fw.ydevices.com/YotaPhone2/Firmwares/CN/4.4.3-S01-003-CN1.0.3.32a.zip
7. unzip the file and copy \radio to c:\program files (x86)\yotaphone_flasher
8. run cmd and go to c:\program files (x86)\yotaphone_flasher
9. repeat step 3.
10. run next lines:
fastboot flash modem radio\NON-HLOS.bin
fastboot flash sbl1 radio\sbl1.mbn
fastboot flash rpm radio\rpm.mbn
fastboot flash tz radio\tz.mbn
11. reboot the phone and enjoy 2G and strong 3G signal

Hello!
I try to figure out what you did but I get stucked in number 10.
Actually I flashed my Yotaphone with the chinese radio the first time, but I don't get good connectivity.
Anyways I try to do what you wrote, but when I tipe the first line (first fastboot command), cmd keep saying waiting for the device... maybe is that I'm impatient but nothing happens.
I try other USB ports and nothing works...
So actually I don't know if I'm doing it right or if I have to wait for a longer period of time (10 minutes or more).
Any help would much appreciated.
Cheers!
Hi there,
you don't have ADB drivers installed. Google for "universal adb driver" and install. There is driver included with yota 5.0 firmware (C:\Program Files (x86)\yotaphone_flasher\Driver\Google), but any other adb driver should work as well.
And use original yota usb cable!!!
It shouldn't take more that a few seconds for those commands to execute.

Had the same problem
Hi all, I had the same problem when I flashed russian firmware (YD201) over my phone which originally had honkong firmware (YD206).
I can inform that for me it also worked to flash the Chinese firware with yotaflasher.
However, when I tried to only flash the radio, it seemed it did not work. So I flashed the complete chinese kitkat firmware with yotaflasher and then afterward just removed/renamed the radio folder when flashing the newest russian lollipop firmware. Everything working great now, even was able to do some ota's without any problems since the ota's did not update anything of the radio img's.
And indeed you first need to make sure that you have the fastboot drivers installed and your device gets recognized as fastboot device by your PC.
You can test this by doing "fastboot devices". If you device turns up there as a fastboot devices, then the drivers and connection from pc to phone are ok.
Good Luck!
Thank you deepmnd and tomgaga.
Actually I had to activate developer options... And then reinstall the ADB cause, aparently I had it but it didn't work.
After that the instructions worked perfectly, but I still have network issues.
I don't know if it is because I have a MVNO (Mobile virtual network operator) and the phone has to change between the networks ( the one that provides the network and the MVNO).
I think that when it changes from one net to the other is when I lose connectivity and sometimes I have to search the network and choose it manually.
So this problem actually happened to me and the solution was to activate Roaming services (but I dont' know if is actually the same problem).
Anyways I can see that I connect to EDGE, HSPA/HSDPA and LTE.
For sure there is a way to monitor the network and check wich ones works.
Another guess is that being a phone for the chinese market, and the lack of the 900mhz band is causing this ¿?
So at the moment I'm losing signal just by walking on the street and I live in a big city. It seems that LTE and H works fine but I don't have a a way to assure this.
When I will have a spare time I will try to reflash the phone with the instructions deepmnd provided and see if it will work.
Thank you for your help!
Any advice will be appreciated!!
Update:
I try tomgaga approach I will test it just to see if is the network or my provider
Does anybody know which bands different firmwares support?
Reception is incredibly bad in my case (206 flashed with EU firmware).
It'd be nice if somebody has any info on unlocking different bands for yotaphone2.

Here you have the bands
https://www.frequencycheck.com/compare-devices/qkjseR/yota-yotaphone-2-yd201/yota-yotaphone-2-yd206
I have the same problem as you, I will try this weekend to downgrade to the older chinese rom and check if the reception get better.
And if then to the latest RU rom.

Thanks for that, it helps a lot to clear the situation regarding the two models.
Now, taking in account deepmnd´s solution above, would it be possible to find those missing bands from the original 206 which are not available to the updated (and then international, 201-) version and add them individually, file by file via the fastboot flashing?
I followed deepmnd's instructions, and my phone now connects to GSM/EDGE, which was not possible before using the EU Radio (latest EU rom). Thanks for this!
Unfortunately it now preferably (!) connects to EDGE, although the LTE/WCDMA-Option is prioritized. I can force the phone to connect to WCDMA by using the WCDMA-only-option, but in this case it does not commit a fallback to EDGE if 3G is missing and I have no connectivity at all, unless I change the band-options and force a connect to EDGE. I'd like it to switch between the bands automatically, as my YD201 did without problems (in Germany).
Any hints to solve this problem?
Thanks in advance, Knut

Thank you! I had missed calls and did not know what caused them. Then I noticed this happened when I was not on LTE network but on WCDMA or 2G network. And this seems to have solved the issue for me as well.
