Mio P550 reboots but does not take any touchscreen inputs

You'll need to find the firmware (ROM) image file (Google) and then: Connect the mio p550 to PC
1.put the Button of the PDA in ON position
2. hold the joystick downward and press the reset button
3.choose "Image Upgrade tools"
4.choose "0=Image by USB"
5.intall the usb driver (PC require the drivers). The driver in the
folder "USB driver"
6.open the software "dnw5.0e"
7.(if you want to make a test of connection USB, click the" USB
port/Statute". If all is ok go to step 8
8. click "USB port/transmitted" and to show the way of the file
"MioP550 - Osc260A R05_P09.nb0"
9.press the reset button to restart the mio p550.

Good luck!

oprn that folder and there you find the licence detail and fill in the licence detail and then turn off and turn on device and it will be done.

The important thing is the ampage. If you have your old car charger check the ampage output. A higher amp rating charger will be ok as the p550 will only draw the current it needs. The voltage you listed sounds like a house charger not a portable car charger. cars run at 12v and the output should be something like 5v dc - 1amp (normally anyway).

if you have xp you will need to download microsoft active sync from www.microsoft.com and if you have vista you will need microsoft sync centre, these will be the latest versions and should work fine good luck

Try this : Open your device ( it have 5 screws). Inside next to the sd card reader are two metallic sponges. Take them off ( they are glued on some electronic parts and it's shorting the circuits)

hi
i think you must know the difference between hard and soft reset.

soft reset is the small hole you put the edge of your stylus to reset the device without erasing anything. (software restart)

hard reset (hardware restore) is:

switch the on/off slider button to OFF. keep the joystik pushed UP and without leaving the joystick slide the from OFF to ON and wait about 30 seconds.

do all that while connected to the power charge. I'd prefer you do that with a wall charger, and not with a USB cable connected to your computer (we dont like this charging state from USB ports)

let me know what happened after that. if possible, upload a video showing us what you did.

thanks

It sounds like the device is not reading the ROM card at all. This most likely is not a home type fix. Check your warranty and see if there is a solution there.

Had the same issue with my Mio P550's using an Airlink680W Wireless N Router and security mode WPA-PSK, TKIP & Password. I had to disable "Block WAN Ping" on the firewall and life is good.

BSL

on/off switch in "off" position for at least 30 seconds, then turn it in "on " position, power on and "reset". You'll lose all your data and all the installed programs.
Alternative: using the screen options, go to "system info", and choose "hard reset".
Beware: pushing the joystick down while doing a reset will get you a boot menu with memory-formatting options. Choose "exit".
Otherwise look into xdadevelopers forum (Google it or go to, say,
Mio P550 / P350 ROM upload [Archive] - xda-developers
)
A good idea would be to backup your data in the first place- just a hint.
Enjoy.

Try a other usb cable had same problem new cable fixed it of other device
