Configuring flashtool on Linux to root/install custom roms on Sony/SonyEricsson Android phone

This is the easy simple guide to Configuring flashtool on Linux to root/install custom roms on Sony/SonyEricsson Android phone. Using the windows version of Flashtool is easy but, Linux fans can't find a Windows PC to get the work done.

First of all download the Linux version of Flash tool from Flashtool website.

http://www.flashtool.net

Then ensure that you have libusb-1.0 is installed. 64bits system needs the both  64bit and 32bit. If you don't have it, simply download it using the package manager of your distribution version. 

Now type this command the configure some USB settings for Flashing interface 

Settings are saved inside /etc/udev/rules

create new file for settings using terminal/command line as root (sudo/su followed by password for root)

cp /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/80-persistent-usb.rules

then open the file by

vi /etc/udev/rules.d/80-persistent-usb.rules

paste the following lines to the file.

SUBSYSTEM=="usb", ACTION=="add", SYSFS{idVendor}=="0fce", SYSFS{idProduct}=="*", MODE="0777"

save the file and close it.

then go to the place where you saved the extracted Flashtool-xxxxxx.tar.7z by using 

#cd <place_where_extracted_files_saved> 

Run the program using 

#./FlashTool

wait until "Cloning devices from github project" or any other waiting window closes.

unlock network blocked dongles to use any sim card from any operator using linux

Do you have any dongle bought from any operator who blocked the dongle to the particular operator/network?

sinhala translation is available at ලිනක්ස් මගින් ඩොංගල් අන්ලොක් කරමු.

if you are in a hurry and don't like to read the whole article, simply go to the bottom of the article to know how the dongle could be unlocked.

Reasons to network/operator block the dongle from using the SIM cards from other operators.

• To stop using a sim card from another operator who is a competitor of the operator
• to keep the customer with one operator. it will help to earn more money while keeping the customer with the particular operator. 
• customer can't switch to another operator with the network blocked dongle because the dongle doesn't accept the sim card from any new operator than the network blocked operator.

Reasons to unlock the dongle

• to switch to a new operator because the new operator would provide more efficient and economical packages to the customer
• coverage/signal problems to some places of the country. 
• customer service of the operator is unsatisfactory

Be careful

• most of the dongles comes with a warranty for some period of time. that warranty would be avoid if the dongle is unlocked.
• if the dongle is provided at low cost or on an agreement with the operator, it would be violating the agreement with the operator. sometimes some operators provide the dongles with the packages with the agreements. so, unlocking or using another sim card or package form another operator could be illegal. 
• user will have to pay for the dongle if canceling the agreement.

After all you would need to switch to another operator due to any reason and if you had to buy another dongle to be used with the new operator, never buy an another dongle, try to use the old dongle while buying a suitable broadband or 3g plan from the new operator. don't throw out the old network blocked dongle because it would cost your hard earn money and would pollute the environment.

I'm using a linux (openSuse) operating system in my Laptop and I encourage other to use Linux on their computers. My dongle had cost me a sum of LKR 7829.99 on December 2009 (with one year warranty) without any plan or agreement but it has blocked to a mobile network operator from using another sim from other operators. Still I'm satisfied with the network but I needed to unlock the dongle for a fun because I needed to know is it could be done by my own.



Now I would explain how to unlock the network blocked dongle to be used with another operator.

First of all you need to know the IMEI number of your dongle. then you could find the unlock code using a web site in the internet. I used a web site on this url to get the unlock code for my dongle. ( http://www.mapmyplace.com/calc/ )

then I installed "minicom" to unlock the dongle using my laptop.
simply the linux package manager helps to install the "minicom" using the graphical way. but there's the text mode as well.

on ubuntu or debian based systems open the terminal and type
sudo apt-get install minicom

on redhat or fedora based systems (yum installer) open the terminal and type
su yum install minicom

on redhat or fedora based systems (yum installer) open the terminal and type
su zypper install minicom

then we need to find the place which the dongle is mounted. most of the cases ttyUSB0 will be the place which identifies the dongle.
use 

• "tail -f /var/log/syslog" on debian based systems or 
• "tail -f /var/log/messages" on rpm based systems 

as superuser/su to check whether the ttyUSB0 is the port which dongle attached. unplug and plug the dongle after running the command to find the port easily.

open the "terminal"
log in as root/super user using "sudo" (debian/ubuntu) or "su" (rpm) in terminal

type
minicom -s

will open a window like

then select "serial port setup"

type "A" in front of the "Change which setting?" to change the port attached the dongle
change /dev/ttyS1 to the port which your dongle is attached. /dev/ttyUSB0 is for mine

type "E" in front of the "Change which setting?" to change the Bps/Par/Bits

type "C" in front of "Choice, or <enter> to exit. it will select 9600 for current speed.

press "enter" to exit from the menu

then it will show a window like

Press "esc" to go to previous/main menu

select "modem and dialing"

it will initialize the modem. don't worry any message didn't come. then select exit from main menu

then the window will go off and will show command line to unlock the dongle

then type the command to unlock the dongle.



AT^CARDLOCK="12345678"

command should be in capital/uppercase letters and the 12345678 should be replaced with the code you got for the IMEI  of your dongle. unlock code should be within double quotes " and ". then press enter to continue.
it should show a message like "OK" or something if you done properly.

AT^CARDLOCK="12345678"     
OK                                              


you've done.

then insert SIM card (from previously blocked operator) in to the dongle and use it.

thank you Girobiro's blog for the article about "Unlock 3G USB Dongles in Linux" helping me to get an idea how to unlock my dongle.

recover the boot loader and start the computer - Super Grub Disk

Threre are several operating systems in the world and most of them are far differ from the other. It's useful if we have different operating systems. But, how could we buy two computers to install that operating systmes. It's no need to own two computers anymore. 

try to install both operating systems on one computer as dual boot. If you need to use the operating system , you need to boot the system using the desired operating system. Using VMWARE or VIRTUAL-BOX helps to use one operating system inside the another operating system, but we can't feel the real power of the operating system when we run one opearting system inside another.

If you have installed two operating systems in to one computer (may be on laptop or desktop) you need to ensure that the boot loader is installed properly. so, you need to install the latest operating system just after installing the previous version. If you installed windows xp after installing windows 7 or windows 7 after windows 8, it will overwrite the boot loader and will hide the operating system previously installed.

Anotherthing is when you installed any linux distro and if you installed windows operating system on to a partition in the computer, it will simply hide the linux operating system and boots in to windows. but this will not effect to dual boot systems if the both operating systems are linux because linux identifies other linux operating systems well.

if you lost any of the operating system after installing the second operating system, you could use "Super Grub Disk" to recover the boot loader. it could be use to boot the computer using a Live USB or CD.  no need to install anything, just select the desired menu to find the boot loader list and boot in to the latest operating system and then repair the boot loader. it will ensure the boot loader is installed properly.
