this guide is probably not user friendly. im a long time htc user, and am just showing how i successfully converted my ATT A9 to the USA Unlocked A9 version 1.12.617.6
this should work for any A9with the MID: 2PQ912000
if you have another MID like 2PQ910000, it may work but i cannot test -see step 2b (thanks @alray)
i also cannot test to see if this ACTUALLY unlocks the phone, because i dont have a nanosim from another carrier
finally, i am not responsible if you mess your device up and make it unusable, this worked for me.
i used SuperCID, 11111111, but this also may work with the cid of the unlocked phone, BS_US001.
Note: if youre using a different cid and/or mid you will not be able to install OTA updates. (thanks @htconeXX and @JochenP)
Extra Note: if you used superCID already, you can change it and try OTA again without reflashing, given you have not modified /system (tested by me)
prerequisites:
1.12.617.6 RUU: Here
drivers, bootloader unlocked from htcdev, s-off using sunshine YES PAY FOR IT IT WORKS AND THEYRE GREAT PEOPLE theroot.ninja
fastboot and ability to use command line
steps:
step 1: boot into DOWNLOAD MODE
this is the BLACK SCREEN that you can get to from the bootloader
from cmd, run
(or use the hardkey method)
which which will take you to the WHITE BOOTLOADER SCREEN
from there, navigate to "reboot to download mode" using the volume buttons and select with the power button
or
by turning off the phone, and holding the power + volume down buttons until you see the htc logo
step 2 change cid
once youre in the BLACK DOWNLOAD MODE screen, from your computer run
from the command line (or fastboot oem writecid 11111111 for SuperCID)
(step 2b if your mid is something other than 2PQ912000 you can change it with the command
which should allow you to flash the RUU (thanks @alray) )
then run
step 3 go back into download mode, verify it says the cid youve chosen , and run the RUU you downloaded from above. follow the onscreen instructions to update your phone to 1.12.617.6
step4: re root, install recovery.
