Bought a Flyer with HC on.
I did not want to unlock bootloader htc method.
So I tried this and it worked. Thank You
A few notes
First I downloaded "CID getter" from the market.
CID_001 Wifi model.
So I looked for a WWE GB version and found this RUU_Flyer_HTC_WWE_Wifi_2.27.1114.31_.............. .........
Changed this line to " adb shell /data/local/misc_version -s 188.8.131.52 "
I skip this line " fastboot oem lock " , as you only need this if you have unlocked the bootloader
RUU installed first time, if you get a error, you have wrong RUU.
S-OFF and Recovery via Revolution
No rooting needed, as I went in recovery and install a GB custom rom already rooted
About 40 mins to do everything.
Hope this helps some one
