Ok so my android phone isn't that popular its calleed the samsung transform ultra and I was trying to find a firmwire for the phone but can't find it at all so I was wondering if I find a update for samsung phone for 2.3.4 and put my phone into recovery mode and choose update phone from sd card and choose that 2.3.4 update that was not made speciffally for my phone can I use it? Or is there an app that will back up your stock firmwire? And save it to your sd are computer so that if anything bad happen I could just reinstall the firmwire??
