[ARC/ARC-S]Autoroot for unlocked bootloader - no flashing needed

[Bazoocaze]

Hi

This is an automated rooting to Xperia ARC / ARC S with unlocked bootloader. No flashing needed - so this does not wear your internal kernel flash memory.
It's a "connect and press enter" solution - no command typing.

You must have the ADB and Fastboot drivers installed and configured.


Compatibility

Tested: ICS .431 and .587
Must work: GB roms


How it works

It boots "in memory" an alternate kernel carefully crafted to root the system, and then rebooting into the original kernel of your phone.
It install the Superuser APK, su binary, and BusyBox.


Requirements

- ADB and Fastboot drivers installed and configured.
- Unlocked bootloader
- Settings - applications - Unknown Sources (first option) checked
- Settings - applications - development - USB Debugging checked
- Press the thanks button on this forum

Included

- BusyBox v1.18.4
- Superuser APK
- su binary


How to use

- Download the latest script version in the [Script downloads] section
- Decompress the 7z file to an empty folder
- Run the file runme.bat
- Connect your phone (powered on)
- Wait for the blue ligth (fastboot mode) on the notification LED
- Press ENTER to root
- Enjoy (and then press the thanks button on this forum )

FAQ

[Q] How to install ADB and Fastboot drivers on Windows?
[A] The most annoying process is to install and configure the ADB and Fastboot drivers, but you can use the Flashtools bundle to install the drivers for you (search for Flashtools on the forum). Simply download the latest version of Flashtools, fire the installer and then choose to install ADB and Fastboot drivers. This way you will have installed the drivers.

Flashtools latest version: http://forum.xda-developers.com/showthread.php?t=1000012

Later, to configure the drivers, you must let windows bind the driver to the device. To do this, you must:

- ADB driver: connect the phone, powered on, to the PC, and then let Windows configure the driver automatically

- Fastboot driver: connect the phone to the PC in Fastboot mode. To do this:

1) Switch off the phone
2) Press and hold the menu key
3) Connect the phone to the PC via USB cable
4) Way a few seconds for a blue ligth on the notification LED
5) Release the menu key
6) If you get the blue ligth you are now in Fastboot mode. Let Windows configure the driver automatically.
7) To leave Fastboot mode, disconnect the USB cable.

[Q] I cannot get the blue light during the script execution?
[A] Verify if you have correctly installed and configured ADB and Fastboot drivers. Maybe you still have a locked bootloader - if you wish to try to unlock your bootloader, see the tutorial / guide threads on the first page of the forum.

Yes! And it's working flawlessly on my unlocked bootloader Xperia Arc, so I expect it to work for you too.

The idea is "no command typing" and "no extra downloads / file copying", so this is way easy (at least for me, a lazy dev).

 

[Sandro8771]

You know now I am a bit scared.
Because after reading the FAQ on how to install adb and fastboot and the configuration part.
Anyway iam going ahead with this attempt.Wish me luck,I will need it.

Guess you are right, but I need to get into cwm anyway at first boot after a firmware flash (Aroma + mods) and I have a bat file executing my hotboot for me.

How hard is it to read requirements?
You need to have unlocked bootloader. That's what fastboot is calling root.

And fix your caps lock.

well looks like I cannot do this as my LED does not turn blue when connecting which means I cannot unlock my bootloader

It doesn't say that its unlocked, but that you are allowed to unlock it.

Sorry to ask this but you are saying .42 rooted still can get "ota" update to .62 to retain root, is it still available to update, I thought their ota only for ics, no more .62?

Edit
I'm ota to .62 right now, thanks.

LED goes blue (fastboot mode) only WHEN you have an unlocked bootloader.
To see if you have an unlocked bootloader, try this:
1) Switch off your device
2) Press and hold the menu button
3) Connect the device to the PC via USB cable
4) Wait for the LED to turn blue (fastboot mode)
5) Release menu button
6) Disconnect to leave fastboot mode
If you get blue LED, you are in fastboot mode, and so you have an unlocked bootloader.
The device default setting is locked bootloader, so you must unlock the bootloader to get your bootloader unlocked - hoho. If you want to unlocked your bootlaoder, see the guide/tutorial stickies.
