Band Issue was fixed with the latest update....
****************************
I investigate more about it and the problem is only in VODAFONE DE hardware so far, so I can say is safe to do ---> Do not change from 821 to 820 your bands will get screw, always will show the LTE bands for the 820, even if you flash back to 821 pre-portico and portico. Now my phone is not working properly, every time I go in network search the phone reboot...any help from anyone will be appreciated?
****************************
I am going to explain in an easy way, assuming you have some basic knowledge to flash any other produces like 820 to another 820 or from 821 to another 821:
Case 1: Nokia Lumia 820 or Roger Product RM-820 to International Version RM-821
a. Do not connect the phone.
b. Download the FW that you like.
c. Create the folder in ….\Products\RM-820
d. Copy the files for the RM-821 FW that you previous download in that folder.
e. Open NCS, open product, select RM-820 and it will highlight the FW that you put in that folder.
f. Press start, the NCS will validate the FW and explain to press volume down + power and retry key to proceed to flash.
g. At this time with the phone off, press volume down + power and as soon the phone vibrate, connect to usb and press retry.
h. That is it. Your phone from RM-820 will be recognizing as RM-821.
Note: The original product code will always remain.
Case 2: Nokia Lumia International Version RM-821 to 820 or Roger Product RM-820 or any product converted before as RM-821
a. Do not connect the phone.
b. Download the FW that you like.
c. Create the folder in ….\Products\RM-821
d. Copy the files for the RM-820 FW that you previous download in that folder.
e. Open NCS, open product, select RM-821 and it will highlight the FW that you put in that folder.
f. Press start, the NCS will validate the FW and explain to press volume down + power and retry key to proceed to flash.
g. At this time with the phone off, press volume down + power and as soon the phone vibrate, connect to usb and press retry.
h. That is it. Your phone from RM-821 will be recognizing as RM-821.
Note: The original product code will always remain.
I hope that clarify how to do it and help others to enjoying flashing. A thanks click will be appreciated and I am not responsible for any damage caused by this procedure to any of you.

I try again from DEV 821 to 820 ATT fail. From DEV 821 to 820 Roger Working. From 820 Roger to 820 ATT Fail. I old version and Portico to go to ATT fail.
************************************************************************************************************************************************************************************************
For some reason there is no way to change a RM-820 ATT and RM-822 to RM-821. Everything else RM-820 can go RM-821 and vice versa.
