I disassociated a device from my dev kit for another merchant and now associated it with new merchant account, now I would like to move the device back to the previous merchant that is working. I associated previous merchant account to the devkit and entered the activation code into it. I am getting problem to setup the merchant account in final step as mentioned in the screenshots. I have factory reset the device a couple of times, but every time I got white screen as in the screenshot attached you. So please look this issue and suggest me why am I getting this error into this device.
Thanks in advance!
