-===== ClockworkMod, root =====
+==== Get into Recovery mode ====
+  * hold down //Volume Up// + //Home// + //Power// buttons
+  * red exclamation mark appears in the top left corner of the screen
+  * ''# ./adb reboot recovery'' will work as well
+==== Get into Download/ODIN mode ====
+  * hold down //Volume Down// + //Home// + //Power// buttons
+  * or via 3x100K resistors in series connected to the two pins closest to the headphone jack on the USB port(unverified)
+  * ''# ./adb reboot-bootloader'' will work as well
+===== ClockworkMod, root, CyanongenMod =====
+==== ClockworkMod ====
+  * get CWM [[http://www.clockworkmod.com/rommanager|here]]
+  * reboot SGS3 into ODIN mode
+  * # heimdall flash --RECOVERY <path_to_CWM> --no-reboot
+  * reboot SGS3 into recovery mode manually
+  * once in, create full backup of your phone and off-load it via ''adb''
+==== Get root on S3 ====
+It's fairly easy:
+  * boot into ClockworkMod recovery
+  * push SuperSU(search xda-dev forums) via ''adb''
+  * install image from zip
+==== CyanongenMod ====
+There is not much to be written about CM as it's all described [[http://wiki.cyanogenmod.org/w/Install_CM_for_i9300|here]].
+CM works on SGS3, however I was scared off by contacts, "you must create an account" and the fact camera didn't work for some
+reason(despite not being on bug list; might have been mistake on my part).
+  * download pre-build CM release or create your own
+  * reboot phone into CWM recovery
+  * push CM release via ''adb''
+  * //install zip//
+  * //wipe data + factory reset//
+  * reboot
+It's possible CM will stuck in an endless loop on boot up. Possible fix is to do //wipe data + factory reset//, //wipe /cache//, //wipe dalwik//.
+At least this did trick for me.
+===== Restore stock ROM =====
+If you find yourself in a need to restore stock ROM like I did, use backup zip image you've created earlier. You did that, right?
+If you haven't created backup zip image like, for example, me, there is another way.
+Find stock ROM based on your //Baseband version//. You can find these on intranets. They're being extracted from Samsung Kies
+software. And having said that, I don't understand why are these files being taken down under DMCA. So it might take you a while
+to find stock ROM for your SGS3.
+After you've downloaded stock ROM, unzip it and unpack tar inside. Then compare files/images from stock ROM pack with your PIT file
+to see what goes where. Once you're clear on that, get SGS3 into ODIN mode and issue the following command(which is just an example!)
+and have fingers crossed:
+<code>
+heimdall flash \
+  --BOOT boot.img \
+  --BOOTLOADER sboot.img \
+  --CACHE cache.img \
+  --HIDDEN hidden.img \
+  --RADIO modem.img \
+  --SYSTEM system.img \
+  --TZSW tz.img
+</code>

 ==== Tizen ====
-Despite Samsung got S3 with Tizen officialy certified, there is no public release and, pretty much, nothing else.

 Information can be found at [[https://wiki.ubuntu.com/Touch/Devices/i9300]]. However, it seems there are some issues and phone
 isn't much of use on the phone part. This isn't much of a surprise.
+===== Links =====
