HP Prime - usbtool.exe - bluesun08 - 12-10-2013 There are websites which describes the firmware-update of HP Prime by means of the "usbtool.exe". What is the advantage/disadvantage of this update method compared to the ConnKit? Re: HP Prime - usbtool.exe - Tim Wessman - 12-10-2013 That tool can overwrite your bootloader as it has no limits and can fully write anywhere in flash. It was never meant to be publically avaiable and was given to early testers in the Prime development. I would highly recommend not playing around with it. The code that writes to the flash is identical in both, but the connkit one has limits to prevent overwriting things like the bootloader. If the connkit doesn't update properly, that tool will not work either. TW

Re: HP Prime - usbtool.exe - bluesun08 - 12-10-2013 Thank you very much!
Re: HP Prime - usbtool.exe - Erwin Ried - 12-10-2013 If you mess the bootloader, how can you recover it?
Re: HP Prime - usbtool.exe - bluesun08 - 12-10-2013 Good question ...
Re: HP Prime - usbtool.exe - Tim Wessman - 12-10-2013 There is a special software tool that is supposed to be able to do this, but I have no personal experience with it at all. Edited: 10 Dec 2013, 1:56 p.m.
Re: HP Prime - usbtool.exe - fabrice48 - 12-10-2013 In general situation like embeded electronic's : Re: HP Prime - usbtool.exe - Mic - 12-10-2013 USBToolkit right works for that.
Re: HP Prime - usbtool.exe - Namir - 12-10-2013 I highly recommend following Tim's advice. A few days ago, I experienced a problem updating the firmware on my Prime. The error rendered the Prime invisible to my PC (any one of them) as a USB device. The calculator would turn on, display the initial screens, and then be stuck there!!! Plugging the USB cable did nothing!! I thought I was dead in the water. Fortunately, the Prime did not lose its bootloader. Tim saved the day and helped with simple instructions that allowed the PC to once again detect the Prime as a USB device. I was able to update the firmware and the machine came back to life!! Losing the bootloader is akin to playing Russian roulette with your HP Prime!!

Re: HP Prime - usbtool.exe - Erwin Ried - 12-10-2013 What are these instructions? I am always a bit scared playing with devices I don't know how to restore (i.e. makes me feel safe to know I can reflash wrt into my router via the programming pins)
Re: HP Prime - usbtool.exe - Les Koller - 12-10-2013 I did just that, and HP sent me a zip file with usbtool.exe in it and a PDF of instructions to use it, and it worked flawlessly!. It is marked HP Confidential at the bottom, so not sure whether it should be posted here or not? To err on the safe side, I won't, but email me if you have questions about it.
Re: HP Prime - usbtool.exe - Namir - 12-10-2013 Hold the Symb button while you use a pin to do a reset on the back side of the calculator.
Re: HP Prime - usbtool.exe - Les Koller - 12-10-2013 I've tried sending the files with both yahoo and gmail, but they won't allow me. Any other ideas?
Re: HP Prime - usbtool.exe - Erwin Ried - 12-10-2013 You can upload it to skydrive, google drive, etc?
Re: HP Prime - usbtool.exe - bluesun08 - 12-11-2013 i also interested in the instructions. i send you a pm.
Re: HP Prime - usbtool.exe - bluesun08 - 12-11-2013 What are the differences between the following resets: Re: HP Prime - usbtool.exe - bluesun08 - 12-11-2013 I have the same problem. The calculator would turn on, display the initial screens, and then be stuck there. (x^2+y^2=1). When i press "ON" the calculator go "Off". Can you give me detailed instructions how to fix this?

Re: HP Prime - usbtool.exe - Joe Horn - 12-11-2013 Quote:1. Simple warmstart. Restores most recent power-up state. 2. Enters recovery mode (firmware update mode). 3. Not a reset. Same as turning on (unlike turning on while holding down Symb, which is the same as #2 above). Quote:Reflash the firmware. The currently supported (safe) methods are: (A) Run the Connectivity Kit, right-click the calculator (if it appears in the list), and select "Update firmware". If it does not appear in the list, use method B instead: (B) Run the "Updater.exe" program directly from the installation folder of the Connectivity Kit. A third method is floating around which involves running a very dangerous program called "usbtool.exe" which has the possibility of nuking your Prime's boot loader. Don't use "usbtool.exe" unless explicitly instructed to do so by HP, and even then be VERY careful to follow their instructions exactly or you'll brick your Prime.

Re: HP Prime - usbtool.exe - Namir - 12-11-2013 See my comment above.
Re: HP Prime - usbtool.exe - bluesun08 - 12-11-2013 Just a minute! Do i have to enter the recovery mode before i can update the Prime firmware with ConnKit or Updater.exe???
Re: HP Prime - usbtool.exe - Tim Wessman - 12-11-2013 The updater.exe does not set the device into update mode. The connkit does that.
1. If you calculator is running normally, it will show up in the connkit tree. The firmware update command a)sends a command to the calculator putting it into update mode and then b) launches the updater.exe TW
