Converting S5 G900F to G900M to add band - GSM-Forum

Socketz · 07-25-2017, 19:35

Hi,
I got a Samsung S5 G900F which I bought in Amazon because it's the "international" version.
It doesn't work in LTE in my country because it lacks band B4.
I enabled all missing bands by editing ID 06828 and ID 06829 with QXDM (setting the last 4 digits to 3FFF), but the phone still works in 3G mode.
Yes, there is 4G coverage in my area; I tried my sim in my wife's phone and it works in LTE mode.
I now have a z3x easy-jtag box with samsung activation and I would like to know if it's possible to enable band B4... and what are the steps I need to take...
Is it possible to convert this phone to a G900M or G900H (which do have band B4)?

Thank you for any help!

As far as I know the hardware is the same for all Samsung S5 and bands are restricted in software.

The modem bands may differ any ways you can't change the bands cause it is different model and it is risky and may cause phone death you can try to root and edit the network bands

I did root it and as I explained I added ALL bands by editing ID 06828 and ID 06829 with QXDM... but it still doesn't connect to LTE, only 3G.
