First of all, if you want to unlock your phone, check the date of manufacturing first! It is well documented here plenty of examples of newer phone brick when unlocking bootloader, so better be careful!
Secondly, if you ran into problem, you need to re-lock your phone using flash tool. Then re-unlock again! I previously lost my phone GSM radio when unlocking bootloader (while on GingerExperia). I have to flash into stock ROM (it's a must) using flash tool, and relocked again.
Finally, it is safest to unlock bootloader in stock rom.

No, you don't need to unlock it again. BL is the flash partition of the phone, what contains a secret code. When you unlock the BL, you'll remove the code and the flash partition will be open. When you flash a new ROM, it changes the system partition. When you flash a new kernel, it changes the flash partition but nothing else. So you'll not need to unlock BL again.

S1 Boot problems

HI Guys,
Today i tried 40 times to install S1 Boot drivers.
How can i make it work , cauze i want to install custom ROM.
Thx

You don't need any s1 boot driver to install custom rom, just root your phone install cwm and flash your custom stock rom. unlock your bootloader ( if you can) and you can enjoy cm10 aokp... All in one thread can help you

Thanks but how do i get in fastboot mode? For root you need to get in fastboot mode?

For enter in fastboot you need an unlockable bootloader but for now fastboot is just for flash kernel. But if you can't you can always root your phone on a. 303 firmware with flashtool install The cwm ( you can find it in dev theard) and flash à custom STOCK rom but you don't need fastboot or Just if you cant unlock your bootloader fastboot is not enable in thé phone so you cant flash cm10 aokp.... Whose need custom kernel

Are you trying to unlock your bootloader?
If so, there's a page of instructions in Sony website. The instruction page will provide a link to download Android's SDK and the S1boot fastboot driver.
Have you done that step yet?

[HELP] Recovery Mode

Hello everyone, i am pretty bad at english so dont judge me becouse of this, and i am also noob here
So, i have problem. Why i cannot enter into recovery mode? I want to flash custom rom in my phone, i already have succesfully rooted with this method http://forum.xda-developers.com/xperia-z/general/guide-how-to-root-10-5-1-0-283-t2872873 and now i want custom rom, but i cant flash it becouse i cant enter in recovery mode, whats the problem? And another question, did i need unlocked bootloader for custom roms? What if i need it but i have already rooted? Did its big risk to unlock bootloader for already rooted phone? Sorry guys i am noob here, thanks for help!

First, did you install any recovery like CWM or TWRP or Phil...
on the page it talks about XZDualRecovery: you may choose any other if you prefer
if not there is no GUI based recovery in Sony Software and you need to install them separately.
Since you have already Rooted the Phone..
1. Start with This, go to the below link and backup your TA partition
http://forum.xda-developers.com/showthread.php?t=2292598
This backup is very important if you want to revert back to factory image so keep it safe. WITHOUT THIS BACKUP DO NOT UNLOCK YOUR BOOTLOADER
2. Only on successful backup of TA, think about unlocking your bootloader. from your dialer dial *#*#7378423#*#*, and check if you have "Bootloader unlock allowed: Yes"
Unlocking the bootloader means you can install any of the ROM's available for your phone. If you don't want to unlock or cannot unlock then you may be restricted ROM's with Sony Kernels only.

Rashr app help

Hello my friends i just want to ask you about an application that i just install to my HTC One m7.It's called Rasrh.
I'm thinking about to flash from this app TWRP touch recovery.
Should i do it?
If i do it i will lose all my data from my phone?
I don't want to use pc to flash custom recovery and I'm trying to find another solution.
Sorry for bad English.
I don't want to advertise anything.
Thanks for every help.

I use flashify, and it works great

Will it erase everything in my device of i install custom recovery with this program? Also I'm S-ON will i have a problem?

Flashing a custom recovery doesn't wipe any data, unlocking the bootloader will. Is your bootloader unlocked? It must be unlocked to flash a custom recovery, even if flashing from an app.

Oh i understand now.Now my bootloader is Tampered-Relocked so i will have to unlock it and erase everything.Thanks my friend.

Hello, I want to unlock my bootloader on my phone, but I don't have bootloader unlock code and i don't want to pay for any service and I just wanted to know if it's possible to unlock bootloader with custom firmware or just install custom recovery (TWRP) i know it's possible and i had tried it but idk how to open EFI.img in UPDATE.APP, and in 7-Zip it just says "Unsupported data format". So is there any program that can open it and change data?
