How do I reset my Revo?
If you find that you cannot exit a program normally,
move to the System screen and select the List open
files command from the File menu. Select the
program from the list and tap the Close file button.
If this does not work, or if your Revo appears to have
“locked up”, perform a “soft reset”. This should restart
your Revo while preserving most of your information.
Use a soft reset if the keys on your Revo do not
appear to respond, or if your Revo does appear to
switch on and you are sure the battery isn’t too low
(especially if the contrast adjustment still appears to
work), but the screen is otherwise blank.


· To perform a soft reset: open your Revo, then
gently press something like an unfolded paperclip
into the reset hole marked ‘1’. Do not insert
anything in the hole marked ‘2’ at the same time.
After a soft reset, your Revo will ‘beep’ twice when
you switch it on. Any changes to open files, messages,
or OPL programs, will be lost. Files and messages
which are not open will almost always be safe.
It is possible (although unlikely) that a program failure
causes the soft reset to lose the information on your
Revo; it could even prevent the reset from working at
all.
If the soft reset does not fix the problem, you will
have to perform a “hard reset”.

Important warning
A hard reset resets your Revo completely, and all
information on the machine will be lost.


· To perform a hard reset: open your Revo, then
press both ends of an unfolded paperclip into the
reset holes marked ‘1’ and ‘2’ at the same time.
Press the On key twice to switch on your
machine.
To switch on your machine after a hard reset, press
the Esc (On) key twice. Your Revo will beep once
when you switch it on. If your Revo beeps twice, you
have performed a soft reset. If this happens, perform
the hard reset again, making sure that you press both
reset holes firmly, and at the same time.
Note: If you have backed up your Revo using PsiWin,
restore the files to your machine after the hard reset.

General advice: Before you buy a new cell phone or new tablet, please try the following procedure to repair your device in a software way. First charge your battery, backup your important data if possible and in most cases take out SIM and SD card before doing factory reset. It is impossible to recover your data after doing a hard reset, so online backup is always important. For all of your data, a backup should be done on an external device, hard drive, raid system or media. With or without insurance, if your cell phone lost, damaged or stolen at least your invaluable data is backed up in a safe place. If you are about to sell your phone and you want to wipe your personal data, or if your phone affected with virus you have to do a hard reset. In some cases, you can delete the forgotten password or lock pattern from your device as well. All information is for devices with stock based ROMs. If you are using rooted device, always back up your EFS folder first, containing your IMEI info, etc.! Please also note, that a hard reset operation will not unlock your mobile phone's SIM lock or network lock, but it will remove the unlock pattern, remove the user password or PIN password (NOT the SIM card's 4 digit PIN code). Also note that the firmware version will not be affected in any way, it will not be downgraded, it will remain the same you are using and if you have rooted your device, root privileges remain also unaffected.
