Flash a ROM or the OTA update and use this method to re-root.
Every time I try to install the update, it gets blocked. I am a novice to this, please help!!
I just did help. I offered two viable solutions for you.
Help me to help you. The more information you can give me, the better. Which one do you want? Keep in mind that flashing a stock, rooted ROM may also require that you wipe your phone; the contents of the SD card will remain and your contacts are backed up with Google in the privacy settings (go check them now).
If you're going to install the update you have to do it manually -- otherwise SPRecovery will block it. This is what it's designed to to. If you followed this guide to root you're familiar with the process of manually installing an update.zip file via recovery, so that shouldn't be an issue once you have the file. If by help you mean links to manually download the 83D file, I can do that easily enough and will be happy to do so. If you wish to flash a ROM, well, that's beyond the scope of this thread but it's performed in the exact same manner and I will PM you links to a couple of ROMs you can try. Just let me know what you need so I can help.
