@nolramlb  just so you know, @Himanshu6 suggests this because reversing firmware (software) upgrades has a very real possibility of "bricking" your smartphone (i.e. rendering it useless), particularly if you're new to process/have not done it before/are a "typical" user... Therefore, most of us regulars will not offer advice regarding such a process, as we don't want to encourage you to potentially "break" your smartphone.

 

Over at Xda Forums though, they deal exclusively with non-official firmware (software) upgrades, so among other things, many of the regulars over there have far, far more experience than most of the regulars here - which is incredibly helpful if you get stuck during an upgrade/downgrade process.


  • I can't help you if you don't tell me what mobile device you're using & what version of Android it is running, in English (you can use Google Translate - http://translate.google.com).
  • The more information you can give me, the easier I can help you!
  •  Please kudo this post if you think it has been helpful; or mark it as the "solution" if it fixed your problem, so that other users facing the same issue can find the solution!

As Nolramlb siad to you got to XDA forum with this question, i'm sure you will find answer and method how to downgrade yours model. Coz in this forum i don't think that somebody from Sony will explain you how to unofficial to flash smartphone. I will not do that too. It's not acceptable Slightly smiling Face
