PS I've posted this before in other threads, but there always seems to be some people that appreciate a step-by-step each time.There are many versions of firmware for the same model BlackBerry, official, unofficial and hybrids.
Load OS to BB: Attach BB to PC, double-click Loader (in AppLoader folder, where you deleted Vendor). Delete Vendor: Return to AppLoader folder, highlight Vendor, SHIFT+DELETE. Re-install OS on PC: Go to your browser's downloads section, double-click OS to start InstallShield Wizard. Delete AppLoader folder contents: Highlight any item, CTRL+A to select all, SHIFT+DELETE to permanently delete. Uninstall the OS: Control Panel\Programs and Features, highlight this BlackBerry Device Software, click Uninstall at top. (Folder where you found Loader & Vendor.) If Vendor is not found anywhere, see below to delete contents of AppLoader folder. If Loader still doesn't make new OS available, search PC for "Vendor". If manually deleting Vendor, always hold down SHIFT and press DELETE to permanently delete.Ħ4-bit: Computer\C:\Users\ \Application Data\Research In Motion\BlackBerry\Loader XML After loading OS, perform several physical battery pulls over first 1-2 days for OS to "settle in." Perform first batt pull very soon after OS is loaded.Ĭonsider trying this new desktop app to remove Vendor from several common locations:. In same AppLoader file where you deleted Vendor, double-click Loader to load OS to BB. (Optional/Recommended) Run BBH Tool (formerly Shrink-A-OS) or BB Boss v2.2 (not as updated as BBHT). On PC, delete Vendor file located here:Ħ4-bit: Computer/C:/Program Files (x86)/Common Files/Research In Motion/AppLoaderģ2-bit: Computer/C:/Program Files/Common Files/Research In Motion/AppLoader. (Optional) Use desktop app like BBSAK or BBMCP to backup 3rd party apps. (Examples: Bellshare apps like BerryBuzz & BerryWeather QuickLaunch Shao's apps like Wallpaper Changer & SixTools etc). Conduct Backup to media card within each of these apps. Go through any 3rd party apps with option to save settings to media card. Ensure Remote Backup is enabled AND also conduct a Local Backup to media card. On BB, go to BBM Options, scroll down to Backup section. Following successful DL, run OS file to install OS on PC. *If 100% certain you previously used FF or Chrome on same PC to DL an OS successfully, feel free to use FF or Chrome again. (For leaked versions, browser is irrelevant.)
Use Internet Explorer, not Firefox or Chrome.
(Optional) Uninstall any previous OS from PC.
Here's my updated OS install guide if anyone needs a refresher.
