1.- Is there any difference between the method below, and the one with test pointer?
2.- Im saying the problem is the bootloader cuz i cant pass the logo of sony or sony ericsson depending in the rom i flash, and i already flash al the stock roms for xperia ray, but nothing change. im using flashtool to reflash every rom (.tft file).
3.- I already try pc companion and detect the phone, "restore or repair" the phone, and when i turn it on, appears the logo and thats all.
Using SEUS same, or SUS neither.
by the way, every time i reflash to any stock rom for xperia ray with flashtools, in VER=R409 , according to the guide capital R means not unlock, but it suppose to be unlocked now.

Need Working CWM sony xperia J

I need working CWM for sony xperia J
I already tried and search it for a while and got no luck, most of them always cause my blank screen after startup and exit from recovery menu.
And i try to use kernel vengeance ,http://forum.xda-developers.com/xperia-j-e/orig-development/kernel-vengeance-t2134810 , but i can't access the recovery menu at my sony xperia J
Then i try something called TWRP , from http://forum.xda-developers.com/xperia-j-e/development/tipo-twrp-t2131727 , and nothing happen at all...
I just want to do my backup and restore in case something happen, because there's no custom rom for sony xperia J
FIRST OF ALL: IM EXPLAINING FOR JB CWM, I DON'T KNOW THE METHOD FOR ICS CWM.
Hi, first before do nothing, do you have bootloader locked or unlocked? You can check in the service menu dialing the next code: *#*#7378423#*#*
Then go Service info/Configuration, in Rooting status check if the text say Bootloader unlock allowed: Yes or Bootloader unlock: Yes.
In the first case, when Bootloader unlock allowed: Yes you can unlock the bootloader following the instructions of this website: http://unlockbootloader.sonymobile.com/ or you can use this method for avoid losing the warranty (this work too in case Bootloader unlocked allowed: No). If the case of Bootloader unlock: Yes you must follow the instructions of this post.
Greetings.
i rooted my phone and unlock my bootlader already, and after searching for a long and night, it just impossible.
Since nobody create permanent CWM for sony Xperia J yet , that's why i can't find the working CWM correctly.
They only offer some feature and can't boot , need to reflash it with other kernel without CWM so it will boot again

Help Unlocking Sony Xperia E3 Bootloader D2206

Hi,
I'm trying to Unlock the bootloader on my Sony Xperia E3 D2206, When I do the Special number in the dialer to get to the Service Menu, It says my unlock status is "no"... I was gonna try to flash a custom Recovery/Rom, But I can't unlock, I also can't get into the Fastboot, or Flash mode. I need to flash a Custom Rom because The Stock rom is experiencing major issues. But, how can I "force" it to Unlock the bootloader, or "Force" it to enter Fastboot/Flash mode? Cause I've ran out of ideas.
