[Cautions] before/during UNLOCKING BOOTLOADER

romasalah · Sep 10, 2011

FIRST OF ALL,i would like to thank the_laser for providing us with the tools http://xdaforums.com/showthread.php?t=1253277

I Noticed a lot of confusion here in the process of Unlocking BL -me was one of the confused- so please make sure to do/notice those points before/during unlocking procedure

THIS THREAD IS ONLY FOR CAUTIONS. actual steps are here http://xdaforums.com/showthread.php?t=1254087
THANKS TO 9Lukas5

IF U DON'T KNOW HOW TO USE FLASHTOOL FOLLOW http://xdaforums.com/showthread.php?t=928343

FOR GUIDANCE about SIM lock and which patch to use refer to 9Lukas5's thread and replies.
BUT generally use "qsd8250_semc" if ur phone came
1.pre-unlocked
2.unlocked by code
and use "qsd8250_setool2" if u have unlocked it with "setool"

ANYWAY u can always use the other patch if ur signal is lost after using the first.-i have less knowledge about this issue as my phone came pre-unlocked and didn't try to unlock another one-.

FIRST OF ALL

1.USB Port not broken -can't do any upgrade or unlocking with a broken one-.
2.enabled "unknown sources" from settings/applications
3.enabled "USB debugging" from settings/applications/development. -should display "USB debugging connected" in notifications bar after USB connection IF NOT: pls flash another ROM and root it using aZUZU method as UNlocking won't work for u-.

AFTER FLASHING downgrade aZUZU kernel

4.MAKE sure ur FLASHTOOL -GB ready version- recognize the phone after SE logo displays on ur phone -FLASHTOOL should say "xperia x10 connected" then shows ur busybox version.
5. IF it doesn't recognized ur phone pls...UPDATE ur SE PC COMPANION.

6.if u don't like to update PC companion..USE THIS METHOD as 9Lukas5 describes

You don't need to update pccp or seus. Try the following:

1. open the drivers manager of your pc
2. connects phone in flashmode (without running any program like flashtool, seus or pccp)
3. check if there appears an unkown device, which wasn't there before (if not go on, if yes read under the line in this post further on)
4. no unknown device? Good
5. turn on phone and connect usb cable again and check again for unknown devices
__________________________________________________ ___________________________________
If there is an unknown device, download flashtool 0.3.0.0 (it contains the 2.3.3 adb and flash drivers)

1. In Flashmode is an unknown device: Go to flashtool 0.3.0.0 folder then to drivers and install the exe file you find there

2. After turning on there is an unknown device: extract the x10 drivers archive in the drivers subfolder of flashtool 0.3.0.0 and search manually in that folder for the drivers of the unkown device, then they should be installed.

3. Now check again like I described it above the line for unknown devices, if you can't see them now, try again to unlock your bl.

7.be sure u have disabled all antivirus services and turn off ur firewall

8.close flashtool before starting to unlock BL

9.kill all processes named adb.exe by ur task manager "ctrl+alt+delete/start task manager/processes/sort by name/then kill adb.exe"

DURING UNLOCKING PROCEDURE

10.IF messages like "killing adb server..error" appears. pls make sure again u did points 6+7+8.

11.U HAVE TO WAIT A while and phone reboots in the process

DURING FLASHING Doom kernel v4.0 or stock

12. if messages like start flashing then abort flashing -with GB ready FLASHTOOL- or sending loader then along wait after flashing kernel .sin-with older FLASHTOOL - then u haven't probably unlocked ur BL . SO PLS don't bother ur self trying to re flash the kernel and check if ur bootloader is still locked
DID U follow steps+cautions?!!

13.to CHECK the status of ur bootloader pls download s1tool from

press "DO job" then connect ur phone in flash mode -green LED light-.

14. IF ur phone is UNLOCKED then status should be like this:

Welcome to S1 identify tool

TO CONNECT NEXT PHONES
X10 Xperia,E10 Xperia Mini,E15 Xperia X8,U20 Xperia Mini Pro
LT15 Xperia ARC,MT15 Xperia NEO,R800 Xperia PLAY
PRESS AND HOLD "BACK" BUTTON...

PLEASE ATTACH TURNED OFF PHONE NOW

RUNNING S1_EROM VER "r8A033"

NOTICE THE LOWER CASE letter "r" in "RUNNING S1_EROM VER "r8A033""

14.IF it isn't unlocked u would see UPPER CASE "R" like "R8A033" then try again with more caution then refer back to the thread

AFTER COMPLETEING THE PROCEDURE

15.of course u will see "XPERIA" Logo instead of "SONY ERICSSON" what Doomkernel u chose -v04b or v04-FS-.

16. 'SE' logo stll appears in cases:
1.u still on ur old kernel.
Or
2.u flashed Doom's stock kernel for unlocked bl.

Hi, very good for scared ones to have that thread. One suggestion, I added it to my how-to just now, but it's not needed to update pccp or seus, you only need the 2.3.3 adb/flash drivers. I have uploaded a file which only contains the drivers and explained in the third post of my how-to how to check if a driver update is needed and how to make it. Much easier as use the crappy se programs^^

Regards,

You won't on stock.

Maybe we need to clear up the confusion in the OP when S1tool says SEMC SIMLOCK CERTIFICATE?

This is the information I have been trying to confirm. So I go ahead and use semc bat file? Seems like so much you have to look out for.

MY experience in SIMunlock isn't so much but i added some hints to the thread if there is some evident additions pls post them....

there's a member who used "qsd8250_setool2" for locked sim and had no signal then used "qsd8250_semc' and it worked and restored his signal back

about what S1TOOL SAYS:

Mine displayed: SEMC SIMLOCK CERTIFICATE
and i could unlock it

Some others display:NOT RECOGNIZED SIMLOCK CERTIFICATE
can't assure that they can't unlock bl... I say try to unlock ur SIM first

And...As i said previously,there r member who unlocked his bl with locked SIM

Me too!!

I actually got cought in the confusion of "SEMC SIMLOCK CERTIFICATE"; I thought that it meant that my phone was unlocked using setool2 (because my phone was already unlocked when I bought it, and I don't know how it was unlocked). Anyways with "qsd8250_setool2" I lost the signal and with "qsd8250_semc" I was able to restore it, but only thanks to that post that you mention, because otherwise I would have panic and would't be able to do anything else

I checked my phone with the s1 tool and it showed lower case r, but at boot it still show the Sony Ericsson text

Is anyone aware of this? Is my phone bootloader unlocked?

It is indeed, you just haven't flashed a 'real' custom kernel yet.

If you haven't flashed any custom kernel for unlocked bl yet, your bl is unlocked, but the se kernel is still used --> se logo appears. If you want to disappear the se logo, flash custom kernel for unlocked bl.

Ahh.. Forgot to mention that I did flashed the DoomLord's custom kernel for bootloader unlocked.. But the situation remain unchanged

I was just curious if my BL is unlocked properly

9Lukas5 · Sep 11, 2011

try reflashing the kernel and have an eye on it it gives you any security error, if yes, your bl isn't unlocked. Or test with the s1 tool from the laser, if you can't see a lower case letter, bl isn't unlocked yet.
