The recently released Samsung Stratosphere 4G has been rooted by the guys over at Rootzwizi. The device, which is similar to the original Galaxy S, was released on the 13th and is the first device in Verizon’s lineup of 4G capable devices to feature a QWERTY keypad.This guide will provide a step-by-step method to root your device, however ifyou’re unfamiliar with rooting, it’s advised that you read up on the subject first (check out the Rootzwiki link above) as we can’t be held responsible for any problems you may encounter. Following the advice of the developer we’ll be using Heimdall rather than ODIN due to compatibility, however if you’re familiar with ODIN you’re free to use that.
Before we begin, this DOES void your warranty, so you need to be aware of that. However, if you take a look on the link above, one of the comments suggests how to unroot, which would (in theory) remove all traces that you ever rooted, and therefore bring your warranty back.
Step 1. First things first, make sure you have the Android SDK installed along with the Android Debug Bridge prior to installation. If you haven’t you can grab the installer from here.
Step 2. Download Heimdall from their website and extract the downloaded .zip. I recommend you get the latest version (which was 1.3.1 as of this post).
Step 3. Okay, so now we can get going; put your Samsung Stratosphere into what’s known as Download Mode.If you’re unfamiliar with how to do this, simply turn your device off, then then hold the Volume Down key and turn it back on. Make sure to keep holding the key until you see “Download Mode Do Not Turn Off Target”.
Step 4. At this point, you need to connect your phone to your computer via USB. Windows users will have to install the drivers (you can do this by going into the extracted folder from Step 2 and going into/Drivers/zagig.exe. Using this, just click on “Install Driver” when asked and then disconnect + reconnect your device. Note that you may be required to do a PC reboot.
Step 5. You now need to download these two files: Stratosphere Root.zip and Stock Kernel.zip. You then need to extract their contents to the same folder you extracted Heimdall to earlier.
Step 6. Depending on your system, open either Command Prompt or Terminal and navigate to the folder you extracted earlier and type:
If your device is connected, type the following:
heimdall flash –kernel root-zImage
This will flash a custom kernel to your device, and upon reboot you should see a yellow warning symbol. Don’t worry about that at the moment. (Make sure to read on after the end of the post in reference to this)
Step 7. Now on your device you need to enable USB Debugging, which you can do by going to Settings > Applications > Development.
Step 8. Make sure that your device is still connected to your computer by typing:
and you should hopefully see something along the lines of:
List of devices attached
And afterwards you need to remount the file system by typing:
and again, you should see the following:
Step 9. The required files now need to be transferred to the device and their permissions set accordingly, so enter the following:
adb push su /system/bin
adb push busybox /system/bin
adb push Superuser.apk /system/app
adb shell chmod 4755 /system/bin/su
adb shell chmod 4755 /system/bin/busybox
Step 10. And now your device should be perfectly rooted; you may want to download something like ROM manager from the Market to check.
For those of you who want to get rid of the yellow triangle, my proposed suggestion is that you just reflash the Stock Kernel you downloaded earlier using the same method as above. I haven’t tried this, but if my other Android devices are anything to go by, it should work just fine.
