The Samsung Galaxy S Plus GT I9001 smartphone which followed the 1900, may be described as not so popular to due lack of tasty ROM support. All that will soon be history, with this easy-ter-follow guide on rooting your GT I9001 Android device.
Before you commence the rooting process of your Sony Tablet P, please note than rooting the OS on your device may void the warranty. Any issues or damage that may occur due to rooting your device by following this guide will not hold Android.gs responsible.
Before you begin....
1. Backup all the data on your phone. Data loss is not probable, but may occur on some instances. Here’s how to back-up different types of data you may have on your Android tablet:
Text messages – Use the “SMS Backup & Restore app”,
Phone Contacts – Sync with Gmail, this is probably on already on your device, but it’s worth the effort to double check:
Pictures, Music, Videos, Files etc.– Copy to internal / External SD Card,
Internet & MUMS Settings – Backup all the settings from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names”
2. Make sure your device is charged to at least 75% battery level – provided your battery is relatively new (under 2 years, which is obviously applicable if you’re reading this article anytime close to the publish date). Otherwise try to charge it 100% or consider buying a new one before you attempt to root the Android device.
3. Download Root-i9001-Signed as well as the UnRoot-i9001-Signed into your computer [external links]
The actual rooting process
On your Samsung Galaxy S Plus i9001, enable “USB Debugging”. This is done by navigating to Settings > Applications > Development > USB debugging. The option should be ticket, like in the screenshot right down here...
Now copy the two zip files from above (remember the ones you downloaded to your PC?). You can copy them anywhere, as long as it's not a place difficult to find or too "deep" in the file system on your phone.
Next, remove the USB cable from the Samsung and shut it down. You will need to enter recovery mode.
How to enter Recovery Mode? You need to long press the Volume Down Key + OK button, and holding both simultaneously press the Power Button (good thing nature gave us lots of fingers). Once you enter into the recovery mode, be glad! And then choose the options Wipe data/factory reset as well as Wipe Cache partition. Cleaning up people, cause it's spring time! Course you can do this any season, but just saying.
Look closely and you'll see the “install zip from sdcard”, click on that and you can pick to bravely Root your device or take the path back home and Unroot (provided you rooted in the first place using yours truly's little guide). After you select, press the power button to confirm your selection. Bamm! the process is not beginning.
Last step would be to reboot the phone, after the process is completed. This can happen automatically, in which case good for you go have a coke. Or, if the device appears to be back in Recovery Mode, there's a neat +++ GO BACK +++ option for you to select. One way or another, you'll be booting in the new firmware. Congrats!
