[Q] Bricked bootloader. How to factory reset it? - XPERIA X10 Q&A, Help & Troubleshooting

Like 6 months ago i unlocked the bootloader and unlocked the simlock too.
But now I wanted a custom rom that required locked bootloader, so i locked it.
That's where my problems start. It isn't in fact locked, but it cannot be unlocked again, because s1tool now doesn't recognize my bootloader, therefore cannot unlock it (Flashtool doesn't help either). And the worst part: now it doesn't accept any SIM.
How can I reset this phone now to a state, where it becomes usable again?

Will Upgrading the ROM re-lock a phone I had unlocked?

When you unlock the phone, what gets unlocked ? The phone or your sim card ? Here is my real problem:
I originally had the XDA 1 from T-Mobile, bought an XDAII on Ebay, was told it was unlocked, but it was not. Ran the xda2unlock program from your website, it unlocked the phone so I could use the phone itself with my old SIM card from T-Mobile. Now I see there is a new ROM from O2, the question is, if I run that, will the unit be locked once again, and since the Radio verison on the new ROM is 1.17, and the xda2unlock only works on 1.10 radio stack (as said on the download site here) will I then be stuck with a phone with a new ROM that is once again locked - that I won't be able to unlock ? I don't want to try this unless I am fairly certain it is a safe thing to do... :? :? :?
it wont re-lock the phone if you upgrade
When you unlock the phone, what gets unlocked?
Where is the information stored that determines if a phone is unlocked or locked then ? If it's on the SIM card itself, then I could see that a phone upgrade wouldn't (shouldn't) have any effect. If it's on the phone, wouldn't that lock/unlock information be overwritten when the phone's ROM is upgraded? :?
re-locked
Nope, I unlocked my XDAII then upgraded the ROM to the latest and nope it didn't relock it stayed unlocked!

It's not on the sim card
lock information is found in the bootloader of the device, so it wil be not affected due a normal firmware upgrade
so if I replace the boot loader of the device then will it unlock the locked phone.

Can i do the sim unlock via davinci after i've unlocked my bootloader? - Yes(ish)

I unlocked my X10 bootloader when it was released, since then i've realised I still had credits in my davinci account, so I thought I'd have a crack at sim unlocking it.
The question I have is, will this brick my device if flash the 2.1 software back, perform the unlock and then flash back to cm7?
Maybe no-one has tried it yet, but I'm looking for a sensible answer with some evidence to back it up.

OK, So yes I can sim unlock it with davinci, But now I'm back to having a locked bootloader which is probably because it rewrote s1_boot in doing the sim unlock.
Soooo, now I can use another network sim which is my main priority as i just switched contracts.
But I'd like to have an unlocked bootloader so i'm not crippled and can go back to FXP and not SE GB.
I know I could unlock the bootloader and not have network access but that defeats the object of having it sim unlocked.
Looking back, There are a few things that would make this a lot easier....
Hi!
I had the same problem.
I was able to unlock bootloader and running Linuxdx+GingerDX.
Then i wanted to unlock my phone, did it with davinci app and worked all just fine, but after trying unlock my bootloader again the sime network crashes.
I have tried both choices on my phone both semc unlock and seetool unlock.
The same problem.
Only way to rescue my bricked phone is to make a "new" unlock again.
Now i have paid a unlock a couple of times so i dont dare to try unlock bootloader again.
Well i really like LinuxDX+GingerDX.
I beleuve that i am stock with STOCK kernel and GingerDX until a solution is here...

Many Questions

Phone: Live with walkman
For a while i have wanted to unlock my bootloader but i cant.
I have found a thread where you can unlock your phone using the test point method.
Using this tutorial - HERE
I have some questions
Can i use this method if unlocking the bootloader is not allowed?
Is there such thing as bricking? If i do it wrong will it brick my phone?
Will it effect my INSURANCE (not warranty)?
I have no experience over unlocking via test point method, so I am unable to help with it.
There is no such thing as bricking, although you can get your phone bricked, if you try to update your phone firmware over the air(3G or WiFi), while having unlocked bootloader.
But don't worry about that, chance to make it completely bricked is quite low, if you know, what you are doing.
About the insurance, check your contract details, can't help with that.

About the bootloader:
The s1tool method might work even if the phone is branded but if you want to unlock the boot loader to flash custom kernels and roms you will need to enter to fast boot mode which is disabled in all the branded phones that I know of, you can try to enter the phone in fastboot mode turning it of and connecting the USB cable to the PC and the phone holding down the volume up key, if the notification led turn on blue then you can flash custom kernels and rooms once the bootloader is unlocked if not then you will need to pay to unlock it if that is what you want.
About the brick and the insurance the answer was given in the previous post.
Cheers!!
If i get unlocked will it also allow me to unlock the bootloader?
After some searching.
If your phone has SIM-lock(locked to a specific network), you cannot unlock the bootloader. The only way currently is to pay some money and it will remove SIM-lock and unlock bootloader also.
Can't remember the provider exactly.

[Q] Unlocking bootloader on network unlocked phone

Hi all. Im about to order this phone on ebay and just have one final question. I am unaware if wether this phone was factory unlocked or unlocked from a network. I know on some phones (xperia) if they were network locked at any stage you cannot unlock the bootloader, is this the case with the HOX+?
So basically I want to know is there a possibility that I wont be allowed unlock the bootloader of this phone and be stuck on stock rom forever?

"Bootloader unlock allowed: no", but on a phone that was previously unlocked??

Hi all,
I have a Z5C and I unlocked it in the past. At the time I needed online banking and got annoyed with not being able to hide the fact my phone was rooted, so I restored stock Android 7.1.1 onto it.
I came back to this after a year or two and thought that I could just root the phone again. Lo and behold, it now says the bootloader cannot be unlocked and everyone says that means it's the end and nothing can be done.
Is that true? Is it possible to unlock the bootloader, but then permanently re-lock it somehow? That seems really strange to me, but perhaps that's what happened. Anyone else have any input on whether this can be reverted somehow?
Thanks,
