Have the same problem.
Chinese model, flashed ROW, and regardless of Vibe or not on top of it installed, my second SIM doesn't work.
After testing with different modems, I came to the conclusion that whenever I install a modem that works 2100 and 900 Mhz WCDMA for SIM1, then SIM2 refuses to work.
After installing a modem for 2100Mhz WCDMA only, it should work.
See my post http://forum.xda-developers.com/lenovo-p780/help/test-radios-4-row-t2761568/post52947423 for a list of modems I had problems and no problems with.
Does that solve the problem ?

Hmm... Seems to me your phone is bought and produced in 2014. Try to do this:
1. Flash 124 ROW ROM with a custom preloader you will find around here.
2. Then do OTA update.
3. The update will install for your phone ROW( rest of the world) modem. For me worked(pentru mine a mers ).
4. PM me iff this don't work.

Thanks for your response. So it will.be on experimenting modems but it will be simply trial and hit and risky especially wid a new handset nd im a newcomer. I have already returned one lenevo p780 and this is my second p780. Is there any reference mapping like against which model version compatible with which modem version. Anyways thanks again.

I flashed a stock ROM on moto e 2015 xt1506(Indian) but the ROM was from different country. It booted up and working flawless but the only problem is the Radio is not working. Sim is detecting but there is no signal.
I've tried *#*#4636#*#* and found out that the Radio is turned off. I think i need the Indian Radio files to get the Signal.
Please help me with this problem.

Indian stock rom
Hi ,
I have an Honor 7 PLK-AL10 ( chinese version ).
I decided to flash a custom rom to remove all the chinese apps ans parameters..
So i find the huawei multitool and succeded to change the model from PLK-AL10 to PLK-L01. So next i tried to flash the custom rom "Yoda".
This worked fine but there is a pertty big problem .. ^^"
My sim card is only detected in "2G mode".
There is two emplacements for sim card in the phone, so i can choose the emplacement wich will use 3g/4g network, and the other will only have 2g network.
So the only way i find is to put the emplacement of the card sim in 2g mode so the card is recognize. But not in "3g/4g" mode
Any ideas ?
I tried to flash a stock rom but i'm not sure how to do that.
I put the update.app in the right dload folder, restart the phone with volume +/volume -/power buttons, i saw the installation began but it stuck at 5% during 1 hour ..
I will try with an other stock rom, any suggestions of a stock rom version to use ?
Sorry for my english, i hope you will understand me !
Thanks
Valnuro
You can report the problem to the Rom maintainer.
Yoda rom is for honor 7 PLK-L01 and not for PLK-AL10, even if you modify your model name to PLK-L01 the rom is not gonna work like it should be because component in the chinese version of the honor 7 are not the same than the ones in the eu version.
In the yoda rom specifications section :
Base ROM: MM 6.0 PLK-L01C432B370
