DO NOT turn your secureflag on unless on a stock,signed hboot.
s-on with an eng signed or patched hboot will hard brick your device immediately.(read: permanently bricked,unrecoverable)
in other words,ONLY use the writesecureflag 3 command AFTER running an RUU. never before.
im sure were mostly to excited to want to go back to s on just yet,since we just got s-off
but its a matter of time before this comes up,so here ya go:
-that you know your stock CID and build number(x.xx.xxx
.x for example, xxx=531= tmobile, xxx=401= htc europe)
if you have a relocked
bootloader,and want to reset the lock status to read locked
,reference this thread: [how to] reset your lock status flag
if needed,flash "lock_bootloader.zip" in clockwork recovery,then procede to the following steps.
1)restore your mid,if you changed that.
2)donwload and run an RUU for your most current STOCK
3)open a cmd window. plug in phone,charge only mode,usb debugging on.
4)run the following:
adb reboot bootloader
fastboot oem writecid xxxxxxxx
is your stock CID. example: HTC__001 or T-MOB010)
fastboot getvar cid
(verify your stock CID)
fastboot oem writesecureflag 3
*verify you are locked
