I went on stock rom for better batt life.

I'm going for wanam3.7.
I think I'm not ready for aosp ROMs. Even though the ROM is pretty smooth, the batt life sux and sometimes the launcher FC or stop working. And I'm already missing the airview.

Hi,sorry for disturbing,but I need your help in reviving my gf's note 2

I bought my gf a note 2. I updated to latest version,DMF2, rooted with CF auto root,backup efs.

But I don't know why the phone got no radio/data. After reading through forums,I suspect it's the EFS folder damage? So I restored the efs I backup earlier. At first boot after restore still no signal,so I restarted the phone and got the signal,imei,mac address everything back. But the EFS seems to corrupt again when I reboot the phone the next time.

I then restored the EFS again and first boot no signal,second boot got back signal/imei/mac address everything working, third boot EFS corrupt again.

I got 2 backups of EFS.img at my PC,I tried to restored both but both give the same result.

Never installed custom rom on the phone,just need root to use some apps.

Anybody please advice what to do?Thanks

Bro. U should read this. It's on the 1st post.

Did u check ur imei whether it is the same imei before u update?
Most probably I think u have to flash different modem.

Hi bro,thanks for the quick reply. Yup I did check the first post and did some readings through XDA

But I am not familiar with samsung system. I did flashed the recommended modem(mf1) from ROM XXDMF2-XME as the thread here http://forum.xda-developers.com/showpost.p...2&postcount=134

When should I flash the modem? Before or After restore of EFS? Or the power off time when I confirm the restored EFS is functioning? Very confusing, please guide me, thanks & sorry 

Edit: Yes,my backup EFS imei is correct 1,same with the imei provided in the phone box also

Try flashing older version of the rom. Meaning downgrade. Then change modem. If still no imei then restore ur efs.

Hopefully turns well. U should have posted or asked earlier when everyone is not asleep yet.
Btw referring from  dr. Ketan's post, did u flash the modem first or restore ur efs after flashing the latest firmware?
According to dr. Ketan u should restore efs first and check whether there is radio/signal or not.

Hi, thanks for the help. I couldn't just post the question when I face some problem without digging more into forums/tutorials. I am not noob in android, was messing with Motorola for 2.5 years and now using Xperia, so I know I should find the answer by myself first. But I am Samsung noob 

I forgot I flash modem first EFS second or EFS first modem second,I tried every sequence and still ended up the signal lost after 1~2 reboots. I tried every possibility I could think of, triangle away, EFS repair, asking question here finally. After 4 hours of messing around with the phone, I tried few reboots/shutdown and finally it could still works after booting. I hope this is permanently fixed.    (I not yet flash older fw to downgrade,the problem seems fixed after messing around)

Don't ask me how did I fix that, too many tries & errors I made and I can't really tell which steps fixed the problem.
Early morning drama. Glad its fixed. Try downgrade the FW n backup backup.
Finally would like to thanks for your kind help again,appreciate 

Please share yr arcane secrets
