[TOOL] PRFCreator - easily create pre-rooted firmwares

[zxz0O0]

Introducing my new tool called PRFCreator. With this tool, anyone can easily create a pre-rooted firmware.

What is a pre-rooted firmware
A pre-rooted firmware is a firmware, which already includes root. This is for example important if you want to update the firmware to a version, where there is no public root exploit. To flash a pre-rooted firmware, you need a recovery menu. An unlocked bootloader is not required.

How does the tool work
The tool should be self-explanatory. SuperSU zip can be downloaded from here. [NUT]'s dualrecovery (*.flashable.zip) can be downloaded from here. Recovery is optional and if your device is not supported by dualrecovery, you can use any recovery (just has to be a flashable zip).
Depending on the firmware size and your computer speed, generating a pre-rooted firmware can take up to 7 minutes. The pre-rooted firmware will be created in the directory of the executable and called flashable-prerooted.zip.

The order for the extra files is

1. Extra flashable
   • In the order you added it initially in the GUI
2. APKs

TWRP is recommended for flashing!

Note: If you do not include the kernel in the pre-rooted firmware, it's recommended to flash it afterwards with flashtool (check "system" under Exclude).
Note2: I am not responsible for any damage done to your device or if you end in a bootloop.

Credits
Androxyde - some helpful information about sin files from his flashtool
[NUT] - used his flashable scripts as base
E:V:A - sgdisk utility compiled for arm
dotnetzip developers (note I'm using a slightly modifed version with a bugfix)

Requirements
Microsoft .NET 4.0

I have a question!

• What should I check under 'Include' ?
  

  • Kernel: Personally I recommend to check kernel. For some firmwares it's important otherwise the phone won't boot.
  • FOTAKernel: This kernel is used for OTA Updates. I recommend to include it.
  • Modem: This is the baseband / modem. Some updates can give you slightly better battery life and signal.
  • LTALabel: This is a partition with regulatory informations. It should not really change the performance of your device. I recommend to include it.

  .
• Do I need to include a recovery?
  

  No, recovery is optional. If you do not wish to include recovery you should add this flashable zip under Extra Files to be able to mount system as rw: https://github.com/dosomder/SonyRICDefeat/blob/master/RICDefeat.zip
  Note: If your bootloader is unlocked, this is not needed as RIC will be disabled anyway.

  .
• Can I edit system.ext4 inside flashable zip?
  

  Yes, you can edit it on a linux machine. You don't have to change anything else in the flashable zip. See here for more info: http://forum.xda-developers.com/showpost.php?p=55547862&postcount=246

  .
• What is zip signing?
  

  For a proper flashable zip, zip signing is used. It generates a hashtable of all the files in the flashable zip to verify its integrity. Note that zip signing might double the process time of generating a flashable zip.

  .
• Does it wipe my user data?
  

  No.

  .
• What is extra zip?
  

  With this feature, you can include additional flashable zip files. An example is to include Xposed directly (you can find the flashable zip in the Xposed apk).

Will try this on the next FW release, thanks! :good:

Thanks for the tool. Looks great. I'll try it.

Hi,

Thank you.. Looks really good! What do the Kernel, FOTAKernel and LTALabel checkboxes do? Also, will this work with the latest .133 ftf?

Regards,

Alan

It will include those in the flashable zip. FOTAKernel and LTALabel are not really important but I thought why not include this feature. Kernel is more important and I recommend to always use the kernel from the firmware you're using.

It should work with all the current ftfs (the tool is built for sin version 3).

Thanks for the reply... What is sin version 3? Also, what are your recommended settings? Tick all boxes or just the Kernel box? What devices/ROMs has it been tested on? Sorry for all of the questions! :laugh:

i just used the xperifirm tool to get the latest z2 .323 update, then used flashtool to create .tft, then your prfcreator tool to make the flashable zip. everything worked perfectly fine (many thanks to the dev's for all this nice and easy to use tools btw), this .zip rom should now be flashable from twrp (i got a locked and unlockable BL) no matter what i have installed on the phone right?

Thanks for your help, i'm new to sony devices and my z2 is only 20 days old, i'm trying hard not to brick it

Wow! Is this magic?

There was a dev who would create pre-rooted images you could flash on Galaxy S3 phones... that was something very cool!

So, I should be able to flash the zip this creates and have a "pre-rooted" phone image...

I'd half thought you were creating a root-injected FTF file... but this is actually pretty cool as well... (saves the pain that I normally go through to root the image after flashing it... thankful I have an unlocked boot loader...)

The first byte of a sin file (contents of ftf file, the ftf is just a zip) is the version. Currently Sony uses version 3. Well if I would create a pre-rooted zip for myself I would tick all the boxes. I have tested the tool a handful of times on my Z1C.

Good to hear. And yes, that is correct. I still recommend to take a backup in TWRP before flashing it (just to be on the safe side).

It's actually not possible to create modified FTF as Sony uses RSA2048 signatures. And yeah, the tool is mainly aimed for those on locked bootloader

NICE! I was just waiting for a root method for my Xperia M2 with KitKat.. The only problem is that there's no Dual-Recovery for it... Would be possible to try the T2U Dual-recovery on my M2?

 

[Ticklefish]

Very clever, thanks!

 

[exodius48]

Make for samsung please...

What is the filename of the second file? Are you sure it's created by PRFCreator?

Hi @zxz0O0

Thanks for your reply! This is definitely for locked bootloaders - correct?
