Hi!
I'm just wondering if it's safe to flash the old GB bootloader, the one that allows to use the USB JIG to reset flash counter, and stays with this old bootloader, while using JB ROMs (mainly AOKP or CM).
Is someone using this old GB bootloader with newer JB ROMs??
Thanks in advance.

Thank you!
By the way... is there any way to know wich bootloader version are you using after flashing a new ROM?, I know most custom ROMs (AOKP, CM, ...) don't contains any bootloader, but not sure about others or about Samsung leaks.
So... is there any way to check if flashing a ROM changes the bootloader?

Sir all stock rom did't touch your bootl oader, coz they are zip file and flashing through recovery, and boot loader flashing only with odin . After flashing boot loader will erase your phone. And to flash this do some search first.

Flashing with Odin in .pda section, if I'm not mistaken. I dunno if you can back up your boot loader. But is good to have ICS and GB boot loader in 2 different tar files, just in case you want to switch back.
You can't back up a bootloader on SGS2. And frankly, given the reason you're wanting to flash it (so you can use a jig) & given there's an alternative (Triangle Away), I'd advise you not to flash it.
You don't need to. You only mess with bootloaders when you have a specific reason to do it; I.E the rom you want to use won't boot without a 'recent' bootloader.
Given the risks of rendering your phone unbootable & only fixable by JTAG if it barfs & given there's an alternative, wanting to use a jig doesn't strike me as being particularly sensible.

I've got to give one of the units back and need to decide which.
Since it's possible to flash CW recovery using ODIN both locked/unlocked bootloader devices, is there a benefit to having an "unlocked" bootloader?
I've been able to flash both locked/unlocked as well install Kernels..
I understand, nvflash can't be used on locked bootloader units.. but it seems (from what I understand and have read via searching), most everything can be accomplished via ODIN + CW.
Thanks!

Lock vs unlock means that if you are unlock you can flash kernels made for ubuntu and other linux distro. Locked bootloaders are generally limited to the samsung kernel so it would be harder to flash other things and make some serious mods that would require nvflash.
Thanks for the reply. Will keep unlocked. Cheers.
Sorry for the noob question, but do these ROMs require the phone to be rooted?
Yes, all ROM's require the phone to be rooted.
yo
Start out with HTC Unlock. Lots of info on this site about it.
Then install a custom rom. It will already be Rooted,
After you've learned more, then you make it S-0ff.
Then you can go backward and forward in radio and other
options without worries.

Wrong. You don't need root. You need to unlock the boot loader. All instructions for that are in HTCDev.com
you need to Unlock your bootloader first in order to flash a Recovery like CWM or AmonRA which will then allow you to flash/install rooted roms.
Note: if you are on Gingerbread and are going to flash an ICS rom, PLEASE download the required kernel they provide for you to flash as well as the ICS rom. but kernels are flashed through the bootloader/hboot and not in recovery. unless your S-off. if your'e S-on, flash kernels in bootloader.
I am returning my HTC One, and am trying to put it as close to stock as I can. I have followed other peoples advice, flashing a stock rom and recovery, then relocking the bootloader through fastboot, but once I do that, it wont boot into the rom anymore. It will only boot into HBOOT. Once I unlock the bootloader again, it will boot right into the rom again. What am I doing wrong?

Looks like after relocking you need the Stock ATT RUU to flash it before you can boot the phone which is currently not available . So at this point you wont be able to relock the bootloader , i learnt about it just yesterday when i was trying to exchange my phone.

rom needs to be completely stock and a rooted ROM is not.

So here is my issue. I updated my android on my Xpreia U St25i to KitKat and in the prossess I had to unlock my Bootloader and now I cannot lock it. I tryind flashing it with flashtool with many ftfs that I found on the internet but the result is always the same. After the flash the phone does not start. I click the power button but the led flashes for a sec in green light and thats it. It seems like the phone is stuck into flash mode. If anyone has any ideas, phease help!
Thanks in advance!

You unlock the bootloader to enable boot custom kernels not made by Sony. If you relock it won't boot custome kernels because the bootloader is "locked" to boot Sony kernels only.
You wank kitkat, bootloader must be unlockedm and there is no real reason you will want to relock your phone.

Well one thing is that I cannot update my PC Companion to a newer version so I cannot restore a backup and I read that this is because of the unlocked bootloader. Also there are occasional reboots of the phone with no particular reason.

PC companion is updated regardless of your bootloader, it will update without a phone being connected.
I don't think you can restore backups to custom non-tock-based ROMs with PCC anyway, you must choose stock(or custom stock-based) or custom ROM.
If you want to re-lock, you must use stock ROM and kitkat does not work with it.

OK than. Thank you, and one more thing, does Jellybean work work with stock ROM ? Will I be able to relock the bootloader?

I don't understand the question, what kind of jellybean work?
If you mean custom non-stock based ROMs like CyanogenMod than no.
Ok so after I posted a previous question about not having bootloader access, I've realized there is something wrong with my xzu. HOWEVER, I CAN get into flash mode to flash factory firmware. The bootloader was unlocked using a tool that I downloaded, but without access to the bootloader, I can't flash any custom recovery so I can flash a different rom.
My question is: Can an FTF file be created from CM, or aosp, and flashed using flashtool? There is a guide over at xperiablog (Here), but they don't mention anything about non-official firmwares, and I don't see any in the forums here, so I'm assuming that it's either not possible, or not worth the effort for most people.
Can this be done? I have no other options.

I don't know why you cant get fastboot - the bootloader unlock is done in fastboot mode

I'll take a video of it tomorrow. It doesn't want to respond to fastboot. I never get the blue light when booting holding volume up. It just blinks amber and green real fast, then it's in flash mode no matter what I do. And like I said, I used some tool to do the boot loader unlock, I think it may have even been flashtool.

Okay you must reflash the stock kitkat Firmware, that is the onliest way to recover the fastboot mode.
