Please tell me where we can find working version of "Shannon DM" tool
We definitely do not want our phones automatically connecting to the "strongest" signal available in the area. That system is a total failure in fringe signal reception areas and in many other circumstances. The "strongest" signal has nothing at all to do with which signal might provide the best quality of service.
The menu we are talking about has been standard in Samsung phones for many years.
This allows selecting specific bands to keep locked in and rejection of bands with known service issues despite whatever the phone might think about the signal strength.
In many cases, the phones are quite useless without access to this menu and it's THE ONLY REASON WE PAID FOR A SAMSUNG PHONE.
Now some "security update" has revoked permission for us to run this vital utility. Phones we purchased in good faith have been sabotaged by the seller such that they no longer work.
"security" patch!? What the hell does locking the user out of selecting a channel on their radio have to do with security?
Now people who have been wronged by this are seeking out security exploits to bypass security in order to access this menu again, making the phones far less secure than they were before.
I think Samsung has performed a criminal act by selling phones with this useful feature, then disabling the feature after making the sales.
Last March 2023, I bought a used SM-N975U1 from Amazon, and "HAD" the same issue, but got it to work by fluke!
Until today (2023.04.12) there was no solution, until now!
I am I in FW N975U1UEU7HWB2.
At this point, my device warned about SIM CARRIER setting applied phone will reboot,
Check to see if network selections witch works!
QUOTE ME IF THIS WORK AROUND WORKS FOR YOU TOO, CHEERS!
REDMARKER - The Alliance app does not ask for Knox validation what so ever, at this point, for fw 7HWB2, your option didn't work for me.
