Has anyone tried changing the cid and maybe tricking the flash tool to unlock the bootloader?

As we know, an Android phone is first controlled by the bootloader.
Only the bootloader can read/write the NandFlash, so, if the bootloader is locked, then flashing commands issued by fastboot will fail.
My question is:
If the bootloader is not unlockable by design, how to root a phone?
can any one help please.
i bricked my phone but did the ruu after relocking the bootloader. Now it says relocked in the fastboot mode.
i tried google to look for answers but could not find any.
by the way i have s-off which i guess is a problem.
so could anyone tell the way around it to reunlock the bootloader so i can root and install updated roms .
thanks in advance.

The method is the same for S-OFF as S-ON. Since, you are S-OFF you can use the Guru Bootloader Reset tool in TWRP after you unlock it the HTCDev method.
You do not have to relock your bootloader to run RUU or firmware when you are S-OFF.

to unlock your bootloader you have to use the method made for your bootloader, if there is one.
downgrade is only possible while s-off, btw.

Hi. Many thanks. I used sunshine to unlock and s-off. When I open sunshine again it says it's already rooted and I can't unlock bootloader. Any idea?

if you used sunshine s-off, you are already able to downgrade. if you are s-off with that method, and most others, you dont need to relock to downgrade. just flash ruu through fastboot. for that issue, contact sunshine. never been in that situation but you should still downgrade if S-OFF'ed.
Hi, I awant to root my H901 by unlocking bootloader (V20J). However, my concern is can it be locked again as I will sell it after a month or so and I don't want any bootloader unlock alert at startup? Has anyone tried to relock? Plz let me know, thanks.

To relock the bootloader follow the following instructions:
Put your phone under the fastboot mode
enter the following commands: fastboot oem lock
Keep in mind that while your boot-loader is locked, you will not be able to root or flash ROMs to your phone.

Thanks. Yes I can unlock the bootloader again to gain root but I have read in unlock thread guide that relocking might have unknown results. Have you or anyone else tried relocking personally?

You should not re-lock you bootloader if you have root but if you are going to trade in your phone or sell it then you should definitely re-lock your bootloader after you flash a stock ROM.
Bump..... Anyone successfully relocked bootloader without any error and got rid of unlocked bootloader at startup?

Hey guys, selling my V30 but i unlocked the bootloader. Its an official UK model.
How do i go around relocking the bootloader and removing all trace that i unlocked it.
Can i just use the bootloader oem lock command or something similar?
Thanks.
Flash a kdz for H930 of your choice first (REFURBISH option), then relock the bootloader using the fastboot commands.
