Hi so after i flashed cyanogenmod on my gs4 international version i cant get any cellular connection at all. there are no bars and im im unable to make calls or send sms. my baseband and imei are unknown. i did a surf on google. I tried to backup efs folder with efspro while on stock rom and then restore when i used cyanogenmod. EFSprogam cant connect to my phone eventhough busybox and debug usb is set. i tried to manually change apn but still a no go. So is there a problem with my efs folder? Hope to find a solution soon since cm rocks..
mine also having same issue last week..after flashing some mods my s4 suddenly lost connection.Bar signal up and down like crazy.When i try to access ussd code it show "no network registered".
I try everything such as flash stock rom few times, wipe data/factory reset and do rooting process on every stock roms.But it seems noting chg..At last i send to Samsung service centre to check wht going on with my s4..After half an hour it done..everything back to nornal.I ask to tech person, they inf. that my S4 just missing few digit of imei..So, they might do recovery imei.

I recently try to flash golden eye (tmobile) rom to my samsung galaxy s4.
I used this guide
http://forum.xda-developers.com/showthread.php?t=2363523
however once i finish flashing the rom I realize my internet connection kept dropping so I try calling tmobile to make sure if that area had coverage. Well there came another problem...I could not make calls not even to customer service. Then my brother told me he was calling me and it kept going to voicemail.
So I used clockwork mod recovery to install goldeneye.
After this issue I used odin to install the stock firmware and then I re rooted the phone to install triangle away and delete my counter and repeated the process by using odin to install stock firmware to unroot my phone.
And I am still having the problem of not being able to make or receive calls and worse my internet connection drops. :crying::crying::crying::crying:
How can I fix this problem the phone load regular just my connections to my network is not there
Hi,
So my father had his S4 (9505) about 4 months. But as of today the bluetooth wont turn on. The cool thing is WIFI works (!) as normal.
I tried :
install custom recovery and wipe everything
flash newest rom (even with PIT-file)
flash new modem and nonhlos.bin
opened the device to clean antenna
nothing help....only wifi and normal network 3g/4g still work as normal....
I knew there was once a fix to disable/enable LTE in /data/property/..... maybe there is the same for bluetooth?
is it possible to log this error anyhow ? if yes please tell me how /what program....

Hey,
anyone here with a ZTE Blade L6 and a running (stock) rom? I bricked mine using some chinese adware-root. After flashing a described as "stock" rom firmware image, i had the phone up and running, branded and netlocked by Digicel. With a little dirty work i now have it mostly unbranded and with another modem even online.
Now, my problem is the modem/baseband. Some give me emergency-calls and a working data connection (but only GPRS/Edge), some even the ability to make phone calls. BUT: I never got back the 3g/wcdma. The Mediatek Engineering-Mode tells me, its using the bands 850/2000(2100), 900 is grayed. As i am in Germany, this should be the issue.
Is anybody in here, who has a working L6 rom or knows how to unlock the wcdma-900 band?
My NVRAM doesnt seem to be changed, my IMEIs are still there..
Thanks in advance!
"Even if it was unlocked, your antenna wont do it!" isnt the right answer, it did before so why shouldnt it now? And its just 50 Mhz..
Same here, I need the real stock ROM or a working C-ROM for the ZTE Blade L6, not the Digicel FW. My phone has been "SIM-slot is permanently locked" after inserted a Sim Card which wasnt supposed for this ROM/Provider, it seems.
I would appreciate it if someone has the S- or C-ROM or knows how to unlock the permanently locked slot again. OEM Bootload unlock (via ADB - I needed to confirm the OEM unlocking with the Powerbutton on the phone but it doesnt react) and ReInstalling the Digi-ROM wasnt helpful.
I unlocked mine using the modem of the L5 Plus-rom. The modem goes to emergency mode every few minutes and data isnt working good too (no 3g, even though i fixed the bandmode somehow), but it gives you a little bit connectivity.
Just grab the L5-Rom, mount the system-images of the digicel-l6-rom and the l5 and replace the modem in /etc/firmware with the l5-one.
You can flash the L5-system too (only system, nothing else!, at least NOT the boot.img). But for me it shows a data connection but cant use it..

Nice, as soon I have time, I will give a try on this. :good:

Like said, doesnt work properly. :/ Crashes and disconnect. Well, it´s just my fun-phone to test out some roms and recovs, so it´s not that important.
Ok, since I´ve managed to revive my "playphone", I´ve made a fastboot-flashable nandroid backup. It includes also i.a. a custom recovery from TWRP in an extra-folder.
If someone just need the custom recovery w/o loading the whole ROM, click the 2nd link.

Hey guys! yesterday I just downgraded my device(i9500) from stock lollipop to cm11 and what I realized was that the network signals were gone. Although phone is detecting sim card as I'm able to see all the saved contacts even I am not signed-in with gmail account. I tried restoring the EFS I made when I was on a custom touchwiz lollipop ROM but I think there's something wrong with that backup as that didn't work for me. I know simply flashing the firmware using ODIN would solve my problem but I haven't got internet connection these days neither time as my exams are going on. I've only got 20MB of data to use everyday. So, I can't download firmware as its size ranges in GB's.
I've installed back stock ROM but problem didn't solve. The problem isn't with IMEI as I'm able too see it. Instead of the network name on the status bar when in lock screen , I'm seeing EMERGENCY CALLS ONLY message
Please help me. Better send me the backup of EFS! Thanks in advance
Could be that your SIM tray broke and it simply coincided with the ROM flash.
