Over the last few months, downgrading firmware has seemingly been all the rage. Not because the newest firmwares aren’t great, and not because there’s anything wrong with them—it’s because downgrading is often the last recourse left in device rooting troublesome devices. There are other reasons as well, but no matter what the reasoning is, users of the Asus Transformer can now downgrade as they choose, whether they’re rooted or not.
XDA Forum Member wolf849 has written up a few useful methods for downgrading your Transformer to the firmware you want. There are three methods altogether, the first for rooted users only, the other two for unrooted users only. Let the downgrading begin!
All of the methods are similar in that users have to put a BLOB file onto their internal storage and then execute several ADB commands. This is nice because any user going through the process more or less has to run through the same experience, just with different commands. Just be sure that you’re doing the correct method before you get started because, as wolf849 says:
Note that downgrading method for unrooted devices is highly experimental and may turn your device into worthless brick. Read this WHOLE thread carefully before you start doing anything with your Transformer.
So as always, be extra careful about which method you intend on following, and be sure you fulfill all of the prerequisites. Otherwise, you could potentially damage your device permanently. It should be mentioned that these methods are also compatible with the Asus Transformer Prime as well. As with the Transformer, be sure you’re doing the correct method depending on whether or not your device is rooted.
For those looking to downgrade their Transformer or Transformer Prime, head on over the original thread for full instructions, credits, downloads, and warnings._________
