Rooting the Samsung Admire

On request of the Samsung Admire community, I decided to root another Android phone.

Update: this exploit is also confirmed to work on the Samsung Galaxy Prevail.

The bug I ended up using is humorously similar to the one I used on the Droid 3. I found that whenever an application crashes (via segmentation fault, etc.) a dump file is created at /data/log/dumpState_app_native.log by root, with world-writable permissions. This file’s parent directory is world-writable, so by placing a symbolic link at this location and causing a program to crash, it’s possible to create a world-writable file anywhere on disk.

The Samsung Admire conveniently doesn’t have an existing /data/local.prop, the properties file I leveraged with Droid 3 to get root, allowing us to create our own. The Motorola-specific property I used to prevent ADB from dropping privileges on Droid 3 obviously won’t work here, but the ro.kernel.qemuproperty will accomplish the same thing.

You can download a one-click root script for Linux and OS X here. Feel free to e-mail me if you find this exploit works on other Samsung phones, and I’ll update this post.

Update: thanks to k0nane, a Windows version is available here.

How To Unlock Samsung Galaxy S II android Smartphone?

The Samsung Galaxy S II is the phone the Korean firm deems the successor to its best smartphone so far. And with a 1.2GHz processor, super-slim chassis and feather-light innards, it’s easy to see why. The dual-core race is set to heat up massively over the next few months, with the LG Optimus 2X already released, and the Motorola Atrix, HTC Sensation and iPhone 5 all set to bring the tech to market too.
Unlocking the Samsung Galaxy S2 requires an unlock code. An Samsung Galaxy S 2 unlocked should work on any GSM phone networks or carrier. Most GSM or SIM based cell phones come with a SIM lock which prevents them form working with unaccepted carriers. The unlock code should remove the SIM lock on your Samsung Galaxy S II.
In order to get a Samsung Galaxy S2 unlock code, I would first contact your phone carrier’s support line and request one. Sometimes they will give you one for free and in exchange will need your Samsung Galaxy S 2’s IMEI number. You can get this number simply by entering *#06# on your phone’s keypad and then pressing enter. If you cannot attain a free Samsung unlocking code, then you can go for a trusted online vendor like UnlockGenie.com
You should now be able to use your unlock code and the steps below to fully unlock your Samsung Galaxy S II to other carriers. Enjoy!
