FLOCK - unlocking/unfreezing S8500/S8530 for free could not be any easier!

Big thanks goes to mijoma.
All you do and enter into your phone you do at your own risk. Nobody else but you take whole responsibility for what happens to your phone!
Remember than flashing of phone is a little risky, however if performed properly, risk of damaging anything is very low.

If your phone locked-up all of the sudden - be sure to read this thread aswell: http://xdaforums.com/showthread.php?t=1787648

Most of bada 1.2 and 2.0 final-release (not ones from beta releases) bootloaders should be supported.
You need some knowledge about flashing.

How to check what lock do you have?
Enter *#7465625# code, you will see list of active and inactive locks.

What do you need?
Wave 1 or 2 phone with bada 1.2 or 2.0
For Wave I with bada 1.2 - FLOCK_S8500_b1.2
For Wave I with bada 2.0 - FLOCK_S8500_b2x
For Wave II with bada 1.2 - FLOCK_S8530_b1.2
For Wave II with bada 2.0 - FLOCK_S8530_b2x

Flash the right FOTA file. Turn off the phone, wait few seconds, and then turn it on holding CALL (so you have to press CALL and ENDCALL, 2 keys) key until white screen with red texts shows up. Release keys.

Be patient, FOTA module is calculating 3 codes (Subset lock, Netlock, Unfreeze) for your phone, it can take up to 10 minutes. After you get the code you are interested in you can turn off the phone.

Write down the codes you need. Turn off the phone by holding power button for 15 seconds or taking off battery.

After obtaining code, do procedure below:
[Netlock], 2 ways:
1. Insert an unsupported SIM card, start phone and after being asked about "Network Lock" enter Unlock Code you had written down.
2. enter #7465625*638*Unlock code# <thanks to homelessghost for tip>

[Freeze]
1. Insert any SIM card, start phone and after being asked about "Freeze" make call and enter code you had written down.

[Subset]
Can anyone provide guide?

That's all - enjoy unlocked phone!

Troubleshooting:
Instead of white screen with red texts, usual booting logo appears and then Bada starts, what am I doing wrong?
Make sure you flashed right FLOCK without errors. If you did so, first - flash APPS from the same bada version, but from ROM that does contain .fota (certain APPS versions can have locked FOTA module), second - if it doesn't work - update your bootloader to some newer/another one and write post here containing information what version of bootloader (bootloader, not bada) you had before that was not working.

Important: Be very careful when writing down and entering unlock code.

If you got any other questions - please ask in this thread.
It is possible that some phones are not unlockable this method. Then the code wouldn't show up.

General method concept (if you are really interested in sources or way how it works - please PM me or mijoma) should work for most of "Samsung 3G" phones - like JET, Wave3, Monte. If you are owner of locked phone of this class and you are able to do dumps of memory - please contact with me.

Wow, that's news to me, I've never flashed because I heard it'd brick a locked phone. Now the noob question, which checkboxes should I tick in Multiloader for just flashing bootfiles and FOTA? Boot Change, Full Download or nothing at all? Or does it require one flash for bootfiles and another flash for FOTA? Sorry - the next post from me should contain a hash!

Boot Change, then select directory with bootfiles and file with FOTA. Try to find some tutorial before you do it.

Sorry, I'm looking for other ways of unlocking too.

Does that mean it's safe for me to flash bootloader and FOTA if my phone is only network-locked?

I won't bet my hand for that it is in all cases. But I'm pretty certain it is.
