HTC Kaiser Windows Mobile 6.1 Certificates of Emission?
I used the harem and Android application once and then turn off my phone. When I back on there was a message about an untrusted application etc. I didn't take note and then tried to flash the phone to 6.5. I took the card of mem, sim battery as instructed. The software in the first Kaiser intermittent wouldnt run Rom (trusted certificate error, etc) and then re- put in the SIM card and microSD even harem, or a bunch of other applications would work. Apparently, the phone will not work unsigned applications now Why would this be and how I can fix it? Haret no harem, typo
Is your Kaiser CID unlocked? If so, go to Start> Configuration>> Clear storage system to do a hard reset. After that is completed, the flash ROM of his new assignment. Hope that helps.
