Huawei Mate2-l05 has the same CPU as Huawei P6, is it possible to flash P6's CPU info topic

Hi guys,

I bought a Huawei Mate2-l05 (Chinese model) which I thought will support AWS 1700/2100 but not. The American model (Mate2-l03) uses a different CPU though so it won't help to flash the firmware of it.
However, I found P6s support AWS 1700/2100 and has the same CPU as Mate2-l05.
I extracted both firmware and try to figure out which img file is about the CPU but I am unable to find further information.
The firmwares are about 1GB for each so I am unable to upload them. I am unable to provide the link since I am a new user, sorry about that.

After comparing both files I found only files sizes are different which are:
CRC.img
CUST.img
MODEMNVM1.img
SYSTEM.img
VERLIST.img

I don't know if I am in the right direction that I just replace the img file related to the CPU and then the blocked bands will be released.

Thank you all for your help

PS.
I got a feedback that it might be related to the modem of the phone.
As mentioned above, the only difference between them about modem is the "MODEMNVM1.img“.
Does it mean if I replaced this img, I may be able to unlocked the bands?

Thanks again
