Can somebody point me in the right direction as to how to do this. Is there a tutorial as to how to install TBH files from their app? I am still new and learning all this so here is my situation and options that I know of. I am on 1.9.9 MIUI build and I have TBH's app. I have never went to GB side before. I bought the app and have no clue as to how to use it. I am wanting to go from MIUI 1.9.9 to MIUI 220.127.116.11. I DL the "Full GB (2.3.3) 4.5.602 All in one updater" from the app but it is in a zip file. Do I SBF this .zip or flash with CMW recovery using ROM Manager. I have already made a Nandroid backup. -OR- would it just be easier to DL .602 SBF file and use RSD Lite. Any help on this issue would be great. Thanks in advance.
