After 4.0 upgrade, both the Pro Sticks failed

[mstrawn]

On one of my RPI’s, both the Pro Stick on 978 and the Pro Stick+ on 1090 failed. rtl_test -t
shows two radios with really long serial numbers, that are the same and I can’t change them. I replaced the Pro Stick with a new one and set the serial to 978 and 978 started working on that pi. I am still waiting for a new Pro Stick+ to arrive. THIS HAPPENED DURING THE AUTOMATIC UPGRADE. I created a new image on a new SD card and the problem still occurs.

Try following method.
Most likely it will succeed in restoring serial numbers.

Alternate method on Windows:

Changing Serial Number of Dongle by RTL1090

If you have software RTL1090 installed on Windows, you can use it also to change serial number ofthe dongle

Step-1: Open Command Promt, and give command *
C:\rtl1090>rtl1090.exe /eeprom

(My rtl1090.exe is located in folder C:\rtl1090 , that is why I have used this path. You have to use the path in your computer)

Step-2: Click START button on RTL1090 window

Step-3: Set serial number and press Continue button

If above method (i.e. using RTL1090) fails to restore serial number, try this one (using Windows command prompt):

rtl_test -t shows two radios with really long serial numbers, that are the same and I can’t change them.

This usually means a hardware problem (I know the symptom you’re describing, IIRC it’s actually poor error handling in librtlsdr, but the underlying failure is a USB error)

Couple of years ago I faced same problem, and IIRC, I fixed it by setting serial number in Windows. I am not sure I used RTL1090 or rtl_eeprom.exe
