 |{{:manual:warning-145066_640.png?100 |Warning!}} Installing **newRPL** will overwrite the entire 2 MiB of flash in the calculator. This includes the ROM, and also all user flash banks in Port 2. Using **newRPL** for the first time will also erase all RAM, including __TEMPOB__, __USEROB__, __PORT 0__ and __ERAM 1__. Remember to backup everything, including your libraries in Port 2 before installing the **newRPL** ROM.|
+====newRPL ROM installation Instructions (for Prime G1 model only) ====
+  - **First time install only**: Connect the cable and start **the Connectivity Kit that came with the calculator**. Make sure it downloads the latest Prime firmware version. Do not need to flash it to the calculator yet.
+  - Run the **Prime Firmware Bundler** application distributed with newRPL Desktop. Follow the 3-step process: The first step needs the directory where the Connectivity Kit stores the firmware. This should auto-populate unless you have some custom installation, in most cases no action is needed. The second step needs the location of the firmware file **newrplG1.bin** downloaded from the links above or from Sourceforge. On step 3 simply press proceed and watch for any errors. If it shows success, then newRPL was bundled into the firmware correctly.
+  - Start the Connectivity Kit again, this time update the calculator firmware as usual.
+  - After it's complete, the calculator will start normally. To switch to newRPL, press **On+Symb** to reset the calculator, then quickly **Esc<sup>hold</sup>**. Don't release Esc until you see a message from newRPL saying that "Install will wipe out RAM"
+  - Once **newRPL** is installed for the first time, all future updates can be made using **newRPL Desktop**. Doing it this way will update **newRPL** without affecting the Prime firmware at all.
+  - **Important**: If you wish to update the Prime firmware to a newer version, don't forget to run the **Prime Firmware Bundler** after the Connectivity Kit downloads and extracts the file, and before you flash it to the calculator. Flashing a stock firmware without **newRPL** bundled in will completely remove **newRPL** from the calculator.
 ====How to revert to the stock ROM====
-To revert back to the stock HP ROM that came with the HP50g, just follow the directions above for loading the **newRPL** ROM, the only difference being the ROM file used.  In this case, use the stock HP50g ROM file.  For this case, the contents of the **update.scp** file would need to be changed to reflect this new ROM filename.

-The ROM update will take about 2 minutes during which time a series of hexadecimal values will scroll down the screen.  At the end of the update the total size of the ROM will be printed, press **ENTER**.  If all goes well you will be presented with the stock HP50g screen.

 The latest HP50g stock ROM file (if you don't already have it) is currently available on the **hpcalc.org** website at [[http://www.hpcalc.org/details/7097|this link]].
 The downloadable ZIP archive contains another zip file, **2MB FIX.zip**, which contains a ROM image that can fix problems with Port 2.  Because **newRPL** overwrites all of Port 2, **this ROM file, //2MB_215f.bin//, is required** in order to revert back after the **newRPL** ROM was installed.
+For other models, always try to find a ROM image file that is padded all the way to the end of the flash memory. This will guarantee **newRPL** is completely removed from your calculator and Port2 will be fully functional.
+On the **Prime G1** model, reverting back to stock ROM does not require removing **newRPL**. Press **On<sup>hold</sup>+A<sup>hold</sup>+F** then press any of the shifts **Shift<sup>hold</sup>+Help** to reset the calculator. Very quickly press **Esc<sup>hold</sup>** and don't let go until you see HP logo and you are back to Prime world.
+To completely uninstall **newRPL** from a **Prime G1** model, simply go to the Connectivity Kit folder where the firmware is and delete all files in there (these files contain **newRPL** bundled in). This will force the Connectivity Kit to re-download the latest version of the stock firmware. Then flash the stock firmware as usual and **newRPL** will be gone completely.
