Stock ROM flash error
I did follow the guide how to flash stock ROM and came here:
6. Install *.zip from SD-card
7. Connect your device on PC
8. Run ADB and reboot on bootloader
So I installed the stock from SD successfuly, shut down and bootet back to recovery -> fastboot. Then I wrote to fastboot following "fastboot oem rebootRUU"which rebooted the HTC into a black looking HTC screen. So i wrote into CMD folowing "fastboot flash zip firmware.zip" and after a couple of seconds this came onto my screen:
D:\Downloads\Desire500>fastboot.exe flash zip firmware.zip
sending 'zip' (25034 KB)...
OKAY [ 3.467s]
(bootloader) adopting the signature contained in this image...
(bootloader) zip header checking...
(bootloader) zip info parsing...
FAILED (remote: 99 unknown fail)
finished. total time: 4.958s
I tried it a lot of times but still the same error. DO you got any ideas and why is the step with the firmware.zip neccessary? My phone started anyway...
