How to force 3g only on exynos model?
I've been trying for a while now to force 3g only on my device and by that I mean change HSDPA revision to disable H+.
On my research it seems you can accomplish this by the service menu but I constantly get invalid code errors with special/"secret" codes, only a few work like imei.
Is it possible to access the menu in a different way or maybe something I can change to force the phone on 3g only?
Thanks in advance and if you want to know my reason is because h+ its not good signal but 3g is always strong.
