Hi. To answer you question, you may try this:
First you must root your phone and install custom recovery TWRP.
Here:http://forum.xda-developers.com/lenovo-p780/help/rooting-tutorial-kitkat-t2835605
And here:http://forum.xda-developers.com/len...oot-install-twrp-custom-recovery-kit-t2849538
Now go to my post How about some modems, here:https://drive.google.com/folderview...&usp=sharing&tid=0B2ORIgaV4iacOVpDTDcxYW4taDQ
Download and flash ONLY the ones from EUROPA.
Good Luck.
hello. for now still no sucess, the message "unfortunately the process com.android.phone has stopped" keeps pop up, i tried several modems and none of them work. i will go on trying and them i will give feed back. thanks for the help
hello, maybe could you help me. i returned to the previous version that i had, installed, which is version X-viberom by xakep. the baseband version for that rom is the V52, which i presume is for chinese version. i think that the x-Viberom as chinese version for base.
with that baseband i never had any problem with the SIM cards, the two work without any problem .
the question that i would like you to help me is the following: with that baseband V52 i have to install a chinese rom or is it possible to install that modem over a ROW version ?
thank you very much for the help
hello. i already solve the problem, and after all it was so easy. i disable automatic date and time and automatic time zone and went to apps, phone and then i perfomr clear data and voila, the phone works perfect. thank you for all

gsm signal problems after flashing different firmwares

hey,
I have Lenovo P780 with 4GB ROW.
I have tried to install lot of different custom roms through different methods. I have lost the IMEIs, and I have installed MIUI via SP flash tooll . IMEIs also gone, but after that I have restored very old backup of nvram only (done via other version of twrp)
IMEIs gone back. Right. But from both cards first (SIM1) I have very strange problems as I live in big city.
The phone very long looking for GSM signal, after that It looses signal frequently. The second SIM (SIM2)has the signal very rarely.
When I am going through the city centre the signal on SIM2 was very poor, rather there wasnt any it.
On the first SIM I have porblems with normal calling, but is better than SIM2.
I have tried different radios, all via install via TWRP. That not helps.
I suppose that I have probelm with baseband, kernel or maybe IMSI ?
PLease help me, I havent any other phone which would be as best as that one.
Thanks in advance !

Bro, you are not the only one here. I too was facing the problem and somehow mangaed to get them working.
First go here and follow the steps.
And then flash non-hlos.bin from the ROM which is working for you. And, in this process, my IMEI got lost and I manually had to enter using the tool in the above specified thread.
Best of luck

Both sims detected and No service.

I just got a Note 3 with SD. After years not not running custom roms on my phones ( samsung note 2 days) I came back.
So I tried to flash and unlock the bootloader so I can have a custom recovery,Root and other stuff. I used miflash/adb fastboot rom method and failed, after a lot of google and time on forums I managed to get the phone to work.
The problem is that after 10 custom roms and flashing many different miui fastboot roms and modems files, I still cant get my cell radio turn on no matter what rom/modem.zip or other trouble shooting method I try.
This is my last resort, and that is too beg for help.
Both sims are detected, but "search networks" results in error while searching and dialing *#*#4636#*#* shows the radio is off.
Grateful I will be, for any help!
Thanks

Hi, have you solved the issue? I need help if you can help me please with the same issue

Lost IMEI restored succesfully but the signal never came back

Hello Guys, so as described in the title it all started when i wanted to unlock bootloader unofficially, im not a newbie but didn't expect Xiaomi to act like samsung in terms of making it a big headache to unlock the device...
anyway the unofficial method consist of flashing MIUI 7.1.8.0 while i was on 8.0.x.x if im not mistaken
I had my sim in my main phone in the process so im not really sure when did i basically lose the IMEI, baseband, MAC address all these things but i discovered that i lost them and spent like 2 weeks searching and tryingdifferent tutorials (i have like 50 bookmarks and maybe downloaded like 30GB worth of data!!)
Final/Current situation:
IMEI1 and IMEI2 recovered --> can log in to Mi account
MAC address recovered --> can connect to wifi
Service NOT recovered, phone detect the sim, it shows the sim number in settings, even the access points are read from the sim and shown in the Access Point area but whatever i do the sim card shows No service
last thing i did is i flashed MIUI9 beta official, locked bootloader, stock recovery...
I hope this thread get some attention for me and many others as well...ready to answer any extra clarifications
It's Redmi Note 3 Special Edition (SE)
[Product Code is 2015161 which is for kenzo according to thsi http://en.miui.com/thread-449310-1-1.html]
Qualcomm Snapdragon 650 CPU
