Why unlocking befor flashing?

I want to flash my samsung with the newest firmware from "samsung-firmwares",
but why i have to remove before my simlock (it´s a branded from A1).
And what happens if I flash without removing the simlock?
Thanks.

I also have the same question on my thread, no body seems to know if we can really flash simlocked units.

errors on boot i suppose ?

So Android phones actually combine simlock with different firmware locking (CID lock?) ??
The hell with that, then. In any other phone we can flash the firmware without the worry about simlock.

i rooted mine and it is sim-locked. never tried to flash tho.
just chiming in that we need some sort of confirmation/assurance that flashing is/ain't possible.

i got the same qeustion, mine is root as wel but can some1 confirm that we can flash the phone when its locked?
and is there a way to check if your phone is simlocked??

Mine is SIM lock (i think, never tested) because it was A1/Vodafone branded when i bought it..
After flash the brand was gone, but dunno with the simlock, as i have A1...

you can flash a locked phone without any problem. it will stay locked though after reflashing. if you flash a generic firmware you will get rid of the carrier personalisation.

YEAH...what the proper prepaired????
this my answer..
1) look on my signature (easiest guide unlocking bootloader)
2) flash custom kernel and flash rom (no need back to 2.1 or stock)
3) Yes Unlocking with stock rom
4) It depend on U (for me i wanna the rom with the nice and beauty colour one)
I use "TIM3 v1" + "nAa v8b" ( I mean where u wanna go with fast speed?)
5) YES
6) Use flash tool and download stock kernel (search it on XDA)
7) NO -u can unlock by easiest guide (on my signature there)
8) U can't DIY...(if your phone still under warranty send to them)
for me i got 4 times hardbricked and they repair for me without fee
BUT PLEASE MAKE SURE YOUR DEVICE IS 11W28 BELOW
(see on phone..PULL OUT YOUR BATTERY AND YOU CAN FIND THERE
hope this help

1.The easiest way to unlock bootloader is with s1 tool. Just connect your phone with usb debugging on and open s1tool and unlock bootloader.( It might brick your phone, I dont recommend you to unlock bootloader)
2.Unlocking bootloader does not change your rom, If you are on 2.1 then it will not affect it. Switching between roms is very easy, just use recovery.For kernel use flashtool
3.You dont need to be on stock rom to unlock bootloader, it can be done through custom roms also
4.From my opinion alfs v6+gingierdx is great. It is very fast for daily use but not very good for hd games.
5.Dont know
6.You can always return back to stock kernel using flashtool and stock kernel ftf
7.Your bootloader will not be lock if you go back to stock rom
8.You cant unbrick your phone if it is bricked during unlocking bootloader, you have to send it to sony ericsson for repair

Thanks very much guys, but I am scared if I brick my device as I can't unbrick it then

I told u...check the MFC date (pull out your battery)
see the **W** (date of manufactoring)
If '11W28' = 2011 week 28
bellow 11W28 is safe..
Above 11W29 is risky..
but nobody force u to unlocking it..
but (also) some nice and beauty rom need custom rom
it totally can't run on stock rom...that why i got my 4th bricked yesterday..
and got a new X8 today with 11W23....
release my tension because can't unlocking bootloader

NO.. not for a hardbrick....
check out some newest threads here which hard brick because of bootloader unlock.. almost all of them not solved and go to SE center..

Ya unlocking bootloader is a bit risky!
Be Careful if your planning to unlock it.

Thanks guys for your help, I really apreciate it. For me the date is not a problem. However is there a possibility of getting bricked during unlocking the bootloader? Well atleaset has anyone bricked their device by unlocking the bootloader and fix it without sending the phone?

U mean if we go back to stock 2.1 with unlocked bootloader, we get bricked?

1) What is the best and easiest way of unlocking the bootloader? From 2nd reply.
2) After unlocking my bootloader, how do I switch ROMs, Is it like normal or do I need to go back to 2.1 first AND GO BACK TO STOCK KERNEL?
You don't need to go back to stock. The unlock won't do a thing with the rom.
3) Do I need to be on stock ROM to unlock my boorloader?
I could only unlock my bootloader from stock 2.1 (tried under GingerDX), but from stock it was easy.
4) What is the best kernel and ROM combination for you? - PLEASE ANSWER THE POLL ABOVE.
For me it's FroyoPro 2.3 ans Alfs
5) Can I Sim Unlock my phone later after unlocking the bootloader?
Can't say... mine was simfree out of the box. (If your phone is not simfree be aware! not all can be unlocked and could cause hard brick)
6) How do I return back to stock kernel?
Just flash back stock kernel file.
7) If I go back to stock ROM will my bootloader be locked again?
No, the bootloader cannot be locked again.
8) If my phone gets accidentally bricked during bootloader unlock process, can I unbrick it?[/B]
At home it is really unlikeley. There are special cables that can do the trick, but they need an expertised technician and a lot of money (for the cable)
Hope it helped for you
My phone is a 11W23 white one with cypress and is unlocked. For You what is the best? What You want? Speed, stability, low battery drainage, cool 3D games etc... For me it was little battery use and high speed with a tad of cool UI.. for this FroyoPro 2.3 and Alfs (Alfs is not needed for froyo pro! so no need to unlock only for that)

Ok thanks guys for answering all my questions about unlocking bootloader. All my doubts are clear

[Q] Can I get my guarantee back after i unlocked bootloader?

My X8 was rooted and unlocked bootloader. I know that I will lost my guarantee.
But I have problem with my LCD touchscreen. It's the hardware problem, not software. So, I think I can get my guarantee.
how SEC identify the rooted and unlocked phone?? Can I get my guarantee back??

Re-lock bootloader, flash stock firmware and send your phone to Sony

I read that re-locking a bootloader with a custom kernel installed would brick your phone, is that not correct? I belive the correct way would to be to reflash your phone to stock using SEUS and then lock the bootloader?
I'm not saying that eagleeyetom is wrong, I'm fairly new to this type of thing but I do remember the unlockbootloader guide stating not to relock bootloader with a custom Kernel installed as you'd brick the phone. Just trying to help

thanks for help.
my touchscreen is broken. I wanna change it to the new one.
I should relock my phone, right??
Are they check the software?? I think i've got the hardware problem..

Yeah, you're right. You should first flash stock kernel and then re-lock.

thanks.. i'll try it..

[Q] Does Stock Rom needs Locked bootleader?

Hello. I want To flash 4.3 Stuck Rom For my Xperia TX. Its Unlocked . Should I relock it Or something else ?
please tell me

Unlock is Unlock bootloader or unlocked to work with all sim?
If you have unlocked bootloader just do it next step:
If you want to flash it with Flashtool, you don't need to lock your bootloader.
If you ask for update with Pc Companion or Update Service, furst lock your bootloader and then try.
Best regards.

How to go back to stock and relock the Bootloader?

Hello
i have to sell my device so i want to get it to stock again.
My current Setup:
Bootloader Unlocked, Stock Recovery, Rooted with Magisk, Stock ROM 9.0.0.283
What are the Steps to go Back to Stock and wipe everything?
Ive read that if the bootloader relock again it is not able to unlock the second time? Is this correct? I want to get the Unlock Code to the person who buy it but if its real, he cant use the code anymore..
anyway is it possible to do the job with the Stock E-Recovery in the current state of my phone? Without bootloader Relocked? Or is it necessary to relock the bootloader again?
Thank you very much

Ask the buyer if they want it locked. Personally it wouldn't be worth my time if it couldn't be unlocked again. Better to check first..

If you want to lock (not relock) bl justdownload your adequate firmware from androidhost.ru and flash fw using Usb-otg method.
You can unlock/lock your bl using unlock code anytime you want (provided you haven't changed your mainboard in the meantime).

I thought you wanted to go back to stock. I've already gave you solution to bring back all the way stock.
I m not sure if it's even possible to re-lock bootloader using fastboot when you're on pie.
Bootloader status re-locked still means your warranty is void.

Hey I've tried this otg method but without success
If I try it with the dload folder option and try to force flash the emui updater throws an error.
Even with the dialer code method.. same..
I'm not able to get it to stock.
I've tried the Huawei suite on PC and phone in fastboot mode..same..massage this phone can't be reset or so..
What can I do next?
Current state, halfway working phone that's boot into os 2 times from 10 reboots.
