I rooted my phone using this tutorial and I removed some of the "bloatware" like Kindle, Amazon, City ID, Skype and so on. Today, I saw that there was an update available (2.3.340). I figured that I would have to re-root my phone after the update and that's not a problem, but the update fails every time.
I tried to unroot using the same tutorial, but that didn't go as expected. The last command returned an error saying the device or resource is busy (or something like that). I tried to update again, but it didn't work.
Do I have to restore all the bloatware and then update?
Current System version: 2.3.15
