Q. Help me I can’t find my build in the Model Selection Screen
The Toolkit includes a selection of Insecure Boot Images to cover all the different builds available. As there are very many different builds it is impossible to include an image for every single build but some builds share the same Boot Image. If you have a build that isnt listed on the Model Selection Screen you can therefore use a similar build. The best way to go is up to the next available build as it should offer more compatibility with the build you are using but if that isn’t available then try the next build below your one as it should still be almost identical as long as it is the same version (ie. 4.1.1).
The Model Selection Screen is there so that if a task in the ToolKit requires an insecure kernel [to perform adb root commands] and your phone doesnt already include one, a compatible boot image [with an insecure kernel included] can be flashed to provide adb root access.
If you have a Custom Rom flashed to your phone then it will most probably have an insecure kernel included so it doesn’t really matter if your build is not listed on the Model Selection Screen and when asked [by certain functions] if you have an insecure kernel on your phone you can answer ‘yes’. However if the function fails then your kernel may not be insecure in which case you can flash one from the ToolKit. If you need to do this make sure the right build [or closest available build] is set so you flash the right image for your phone.
Q. What is ADB Shell?
Adb shell is a linux command line tool (because android is based on linux) used to send commands to your android device. For S-ON devices, this is crucial for modifying files in the /system partition (where the rom sits) as you cannot modify anything in /system when the rom is running without S-OFF like removing system apps.
Q. Is there currently no way to root the Samsung Galaxy S3 without voiding the warranty?
All methods of rooting will void your warranty in some way as you will have superuser files on your phone that arent supposed to be there. Flashing a custom kernel or recovery to root will increase the flash counter and also void any warranty. If you dont want to risk it or you aren’t sure then you shouldnt really be flashing your phone and should just leave it alone. Its your choice .
Q. Will flashing Stock ROM via odin using the toolkit replace everything that was flashed before? recovery? etc?
Yes a Stock Image flashed via Odin will replace all your key partitions (boot, recovery, system) with the stock firmware. If you want to reset the phone back to an ‘out of the box’ state then you want to enter recovery and do a wipe first which will reformat your userdata partition.
Q. I flashed Custom Recovery but each time I reboot the Stock Recovery is back
There is an auto recovery restore system on certain Stock Android Builds that will reflash the Stock Recovery if you flash CWM on a Stock Rom.
Use Root Explorer to Mount the system folder as R/W (or use a free app from Google Play such as ES File Explorer). Rename the files /system/recovery-from-boot.p and /system/etc/install-recovery.sh (requires root). Now when you flash Custom Recovery it will NOT be overwritten after a reboot. You can also do this via the Toolkit.
Q. My AntiVirus program says the Toolkit files may be harmful
The exe compiled files are not digitally signed with a Microsoft certificate (as they cost money) so certain AntiVirus programs (mainly Norton and AVG Free) may pick it up as potentially harmful when it is not. They will pick up ANY file that doesn’t contain a purchased Microsoft certificate in the same way. Just Restore the deleted file and exclude it from further scans and it will be fine. Or switch to a better AntiVirus program such as BitDefender.
Q. I am having trouble getting adb working with the drivers installed
Try switching your connection type from media (MTP) mode to camera mode (P2P). To do this open the notification area, click where it says connected as and change from MTP to PTP.
Q. When connecting the phone I get ‘USB Device not Recognized’ and no serial number shows in the ToolKit
I actually had this problem recently and what fixed it for me was to make sure that the drivers have been installed, then shut my phone down plug the usb cable in and restart it. The phone booted up and the device was recognized and drivers installed correctly. May not work for everyone but worth trying.
