Adding LTE bands to Huawei Honor 4X (Che2-UL00)

[LNX9]

Hi,

First of all, I don't know if Kirin processors support more bands than it's actually claimed to, but considering the fact that most (if not all) of Huawei Honor 4X versions (Che2-XXXX) have the same hardware configuration, but different bands compatibility, it might have some software imposed restrictions just like Qualcomm devices have, in which case I'm interested if someone managed to add more bands (specifically LTE800 MHz, B20).

On the internet there is a tutorial for Honor X1 7D-503L, but it's not well written and I can't even understand the software used because it's in Chinese. Also, in Balong Debugging mode my phone shows up in Device Manager using some COM16-21 ports which that program doesn't even have.

I look forward to hearing from you.
Cheers!

Hello, I already bought a Huawei Honor 4X (in fact a friend of mine bought it in China) but unfortunately it does not support band 4 (used in Argentina). I was wondering if it is possible to add more bands to this phone model by soft.

Thanks in advance,
Fernando

Guys, its not software, its hardware thing. You just cant add bands!

If not, how come devices with Qualcomm modems become compatible with previously unsupported bands? I know that in most cases you can't make a phone work in TDD if its hardware only supports FDD, but when the same phone, with the same hardware specs, comes with different frequencies support in different areas of the world, then some restrictions must have been made by software. It very possible to make a phone that is compatible with a certain band not to show it when scanning for it.

Cheers! :highfive:

PS Here is how you can add Unicom China LTE bands to a TDD phone: oiostore.blogspot.com/2014/11/how-to-unlock-fdd-lte-4g-band-support.html
