Unlocking + custom ROM's? - GT540 Optimus Android Development

I'm on Openswift 2.2.1 and I'm thinking of unlocking my phone, I think I'll have to go back to 2.1 to put in the code using a USSD code, but when I flash various custom ROM's, will I lose my unlock?

again no lol

[Q] Unlocking on the official Froyo ROM

I have my unlock code from 2.1 "just in case," is it fine to use in Froyo? Because I thought I heard Samsung was patching the exploit to get free unlock codes, but I already have mine.

[Q] Unlock code and flashing

Hello All;
I am using my AT&T Captivate on Canadian Rogers network with a seller supplied unlock code, as well as a "sgs unlock.txt" file in my phone.
If I ever do either OTA upgrade to Froyo, custom leak upgrade to Froyo, or any kind of flashing such as stock ODIN and such, will the unlock code ever change or can I be using the same unlock code, if the phone ever decides to lock itself again?
Cheers!

Hmmm....good question. I thought i read somewhere in these threads that when you flash ANYTHING (beyond eclair/ jf6 build), that you do lose the unlock code. I could be wrong. These are one of those times that i wouldn't mind being wrong. lol

Root and carrier unlock are different things. Carrier unlock requires a code from your provider.

Would he need to do a carrier unlock even in the case he installs a new ROM on to it? (even the ODIN One-Click stock ROM?)
Sorry, just curious myself!
What he describes is the fact that in 2.1 ROM, carrier unlock code is very easy to extract from the phone (it is not encrypted). But once you flash to any 2.2 ROMs, the unlock code is now encrypted and much difficult to extract but still doable.
Flash back to 2.1 will not give you back the encrypted unlock code. So, it is important that get get the unlock code while still in 2.1 and write it down somewhere.
There are instuctions posted in dev forum about how to extract the encrypted unlock code in 2.2.
Regardless which ROM you are on, your unlock code stays the same unless you flash to a custom ROM that is not properly ported to Captivate and it will likely destroy your IMEI, product code and unlock code.

Ah I see! So much like the CM7 ROM then
So I'm guessing my phone was already unlocked somehow beforehand...
Call ATT, make up some BS about going to Europe on a trip. Tell them you already bought a prepaid sim card for an international carrier and you need the sim unlock code for your phone.

Custom ROM has nothing to do with unlock status.
Exactly, that's what I'm meaning
I've never unlocked my phone, yet it's unlocked.

How do you know it's unlocked? Are you using it on a different carrier than when you first purchased it? Are you using prepaid SIMs in it? That's what carrier unlocking allows. Rooting allows access to the base OS so you can run certain apps and make mods that involve the system. You can be rooted and locked or unlocked and you can be locked or unlocked and not rooted. One has nothing to do with the other.
I never said they had anything to do with each other, I'm much aware of how they both work. I'm both rooted and unlocked (not bound to any carrier, and yes I use prepaid SIMs).

if your phone has root access simply download galaxy s unlock from the market by helroz and run it. it's pretty simple. to know if you have successfully unlock your phone just dial *#7465625# it should should show network lock off. and you"re good to go any carrier sim you want that supports your phone baseband. if you're not at&t way to go....

[Q] Xperia X8 Unlock-Sim question.

Hello! I'm sure I have read a post on the forums about this a few months back but cannot find it for the life of me so apologies if its been asked already....
I want to sim-unlock my SE x8 E15i. The phone was running custom kernel and ROM (with unlocked bootloader).
I've now restored the phone to stock (both kernel and rom) and relocked the bootloader - Its nowe back to "factory" settings.
I'm now ready to call and pay my provider for the sim-unlock code....
My question is, once the phone has been SIM-unlocked am i free to unlock the bootloader to flash kernels and roms WITHOUT loosing the sim-unlock which i have paid for.
I've tried to find out more about how the IMEI number and the unlock code behave (e.g. where the unlock code is saved to. Im not sure if it's in the bootloader. If it is will unlocking the bootloader mess up the unlock codes? etc).
Many thanks in advance.

2 tap to wake for locked bootloaders?

Hello fellows
Is there a way to port or put into the official stock kernel the 2 tap to wake funcionality for locked bootloaders?
Locked bootloaders only can flash official stock kernel, so theres a way to do that???
Cheers
No, as soon as you decompile a kernel and recompile it (Even if you make no changes) you cannot flash it on a locked bootloader.
