Trick with LOCK [not RELOCK]!!! - HTC Desire X

Hi folks,
I found a way how to LOCK device temporarily when it was UNLOCKED. It means in bootloader will be written 'LOCK' not 'RELOCK'!.
1. go to bootloader
2. choose fastboot
3. connect phone to PC via USB
4. type command in you PC (in folder where fastboot and adb commands are)
Code:
fastboot oem readsecureflag
it should return something like
Code:
...
(bootloader) ›ŻtjHTCE
(bootloader) Done!
(bootloader) HWIO_SDC1_MD_REG_ADDR=0xA86000A0
(bootloader) HWIO_SDC1_NS_REG_ADDR=0xA86000A4

(bootloader) Wait for AMSS ready
(bootloader) AMSS is ready
(bootloader) readsecureflag: secure flag: ON
(bootloader) [usb_ep_write] ep1in prime failed (0x0)
(bootloader) ed
OKAY [ 91.385s]
finished. total time: 91.385s
5. In BOOTLOADER choose on BOOTLOADER.
6. Voila, you have it.
It is fully functional LOCK. As test you can do:
Code:
fastboot oem lock
...
(bootloader) Device was already locked!
OKAY [ 1.010s]
finished. total time: 1.010s
Or you can do LOCK again via Unlock_code.bin from HTCdev - works
Or you can update ROM.zip from RUU - works
After reset of phone it will be UNLOCKED again!
Funny is that I discovered it with pure coincidence while I was finding how to install ROM.zip from RUU. Maybe this trick works only for my phone, so will be good if somebody will check it.My problem was still not solved regard wrong EMMC partition, but this trick can be helpful for somebody. Especially for phones where classic method with FASTBOOT OEM LOCK fails with error "Lock failed! FAILED (status read failed (Too many links))"

by doing this can you make the bootloader say LOCKED instead of RE-LOCKED???
EDit: Yeah it says LOCKED sorry I havent read your OP more carefully

Man u don't know how much u contributed to our device.

It's awesome what you've found out dude! But I have one question: It will appear as "Locked" but if you turn off your phone and turn it on again, it will show "Unlocked" right?
It would be awesome if it only showed "Locked" because we could regain our warranty!
Have a great day and thank you!

Holy crap, this is awesome

Hmmm,, is this safe enough?
Can you:
Lock -> Unlock -> Use this metoth to Lock -> Unlock ?

In my method I'm NOT using
Code:
fastboot oem writesecureflag 3
Just only
Code:
fastboot oem readsecureflag
It is safe. For unlock just use standard method
Code:
fastboot oem unlock

Any one tested ?

Yes, it's a trick that shows LOCKED instead of RELOCKED.
Note: your warranty is still void.

Yes but maybe they have another system to see if you unlocked your bootloader or not, for ex. a count like Samsung phones.

After doing that I reboot bootloader, and it showed "Unlocked" again.
