[Xperia Z Q&A, Help & Troubleshooting] camhiliciouz:
Hi everyone!

i hope im not repeating anyone question or asking something that was already asked, because i have search not only in xda but on the web my case and i cant seem to find an answer for this.

so i was trying to root my Sony XPeria Z with the latest firmware .244 and found the guide created by [MENTION=2784807]DooMLoRD[/MENTION]. however, i cant flash the old kernel as there is this persistent error i cant find the solution to. below is the log from my flash tool:

so i was wondering, how can solve this ERROR:

ERROR - ERR_SEVERITY="MINOR";ERR_CODE="0017";ERR_DYNAMIC="0x8009001C ";

i have enable all the necessary tricks such as enabling the usb debugging, unknown sources and the followed the correct installation of flashtool. i did flash the latest .244 firmware via flashtool and flashes the new .244 kernel whenver the old one fails.

so please please please help me!

this is the first time i was trying to root an Sony device since im used to Samsung (Galaxy NOte and Galaxy S3)
