[Desire Q&A, Help & Troubleshooting] ze7zez:
How do I get

*** UNLOCKED ***

or

*** RELOCKED ***

or

-Revolutionary-

or

--- AlphaRev ---

in the header bootloader?

My story is as follows.

1. I bought a second-hand HTC Desire with

- hboot 1.03.0003 *** UNLOCKED ***

- CWM Recovery 5.0.2.0

- CM 7.2.0.1

2. I needed to flash 4EXT Recovery.

3. I did not have Unlock_code.bin

3.1 I generated token:

[FONT="Courier New"]fastboot oem get_identifier_token[/FONT]

3.2 With the help of htcdev got Unlock_code.bin and for checking I have done:

[FONT="Courier New"]fastboot flash unlocktoken Unlock_code.bin[/FONT]

4. With the help of a PC in fastboot mode I locked the bootloader again:

[FONT="Courier New"]fastboot oem lock[/FONT]

Now in the bootloader was the headline:

[FONT="Courier New"][COLOR="Magenta"]*** RELOCKED ***[/COLOR][/FONT]

5. I made a downgrade hboot to 1.02.0001 with RUU_HTC Desire Android 2.3 Upgrade (Gingerbread) .exe

6. When obtaining S-OFF with Revolutionary received the message:

7. I tried the method unrEVOked 3.32 ( nw_28556_reflashpackageexe.exe) - That was my big mistake!

8. Currently I do not have access to recovery.

I can only upload RUU_HTC Desire Android 2.3 Upgrade (Gingerbread).exe again.

Attempting to upload RUU_Bravo_Froyo_HTC_WWE_2.29.405.14_Radio_32.49.00.32U_5.11.05.27_release_224699_signed.exe comes back with no connection to the device.

9. By the Android operating properly adb communication mode.

10. In bootloader mode does not work fastboot connectivity.

No fastboot command does not work, because there is no communication with the device.

It is working properly:

[FONT="Courier New"]fastboot getvar all

It does not work properly:

11. During start-up in bootloader mode LED blinks continuously in pink.

Headline bootloader is different than at the beginning. Simply, there is no first line.

12. After 14 seconds from the entrance to recovery mode, proceed to the update mode.

A second later, a red exclamation mark

I would be grateful for any suggestions on how to regain access to fastboot mode.
