This is a guide for XPERIA ACRO S (other xperia users can also refer needed information)
[Below procedure looks lendy, but you'll just need max 30 minutes if you have every downloaded file.]
I make this guide for noobs as there weren't such guide (even for my first time of flashing ROM I didn't get any such guide, so I decided to make one)
This Guide is especially for flashing BPaul's 5.1.1 ROMs (B3||B2||B1)
To Flash Different Versions Of BPaul's ROM follow Respective Guide:
Beta1 threads POST #13
Beta2 same thread
Beta3 threads POST #40
So here I'm giving detail process to install Bpaul's 5.1.1 with every links needed.
we are going to take below steps;
1. unlocking Bootloader
2. flashing kernel with recoveries
3. backing up stock ROM
4. installing BPaul's 5.1.1
Special Thanks;
@BPaul (for awesome ROM)
@cobrato (for stock kernel)
@jajb (for gapps)
-Here we START-
Note: Before Unlocking Bootloader, I suggest you to Backup your TA Partition. (Trim Area) IF in future something goes wrong with network signal related issues or bootloader issue, you could restore this backup. TA Partition can be backed-up ONLY before unlocking bootloader. To backup TA follow this "Guide" and after you could below steps. Also your phone needs to be Rooted to backup TA, if your phone isn't rooted, follow this "Guide"
*_UNLOCKING BOOTLOADER_*
(unlocking bootloader will erase everything on your phone, i suggest you to take backup of your data)
First check weather you can unlock your bootloader. To do so type *#*#7378423#*#* in dialer and find bootloader unlocked status.
IF bootloader unlock allowed = YES (you can unlock)
IF bootloader unlock allowed = NO (you can't unlock)
IF bootloader unlocked = YES (already unlocked)
Then you need to take unlocking code from official Sony website (link below)
LINK1 Unlocking Bootloader
after clicking on above link, on the page just scroll down
1.select your device
2.provide your IMEI
3.you'll get unlock code (save it properly)
Next you need to download minimal adb and fastboot (link below)
LINK1 Miniamal ADB and Fastboot
install it to your computer.
Now we have to connect phone in fastboot mode, follow below steps
1.Turn on usb debugging mode.
(setting > developer option > usb debugging)
2.Turn Off your Xperia Acro S
3.Press and Hold volume up button and then connect usb to computer.
(If you see Blue LED of phone, then everything is going right)
(Let your computer install essential fastboot drivers)
[If blue LED disappears after some seconds and phone starts charging, that means your PC isn't installing fastboot drivers. In such situation REFER Q&A thread POST #4 ]
Now open minimal adb and fastboot (we installed previously)
Type below command
-fastboot devices
-fastboot -i 0x0fce oem unlock 0x(your unlock code without this brackets)
-fastboot reboot
DONE
(Now you have successfully unlocked your bootloader)
[ To check that if you have succeeded in unlocking bootloader type *#*#7378423#*#* in dialer and find bootloader unlock status.
ALSO you'll notice that your phone is factory resetted]
