Rio Chiba Upgrader Error

try hitting power and menu at the same time see if that helps because its usually what buttons put the player into upgrader mode and see if doing so has the reverse effect

try puting a cf card in it or look up problem on google if this doesnt help hold in menu and power for 4 seconds see if this helps in undoing the upgrader message if not try connecting it to a windows pc with xp or 7

YOU MIGHT HAVE INSTALLED THE BATTERY WRONG RETRY.....YOU MIGHT ALSO HAVE TO REFORMAT

I tried you solution mowcius (except the part about burning it) and it didn't work. It showed up as an unrecognizable USB device in windows Vista and nothing I did got rid of the "Upgrader" screen.
I did get it to work, but remember the stuff I did could destroy the player. It worked for me, but if it hadn't I was going to pull the CF card and chunk the player.
I plugged the  2100 into Vista. Vista stopped responding during a file transfer and the 2100 went into "Upgrader" mode. Nothing I tried worked. A google search gave me this page so i tried it. 
I wasn't going to spend money on a CF card as I already have the broken volume wheel, so I thought "what if I took the CF card out, put it in a CF card reader, re-formatted it, reinstalled it into the 2100, then re-installed the firmware". 
I did that, but I couldn't get the "Upgrader" screen off during all of this. So I figured I'd try something that would either clear it or destroy it - i used a screwdriver to cross the positive and negative leads on the battery for a second. The screen went blank and I figured it was dead as it wouldn't respond to the power button. I plugged it in with the USB cable and the Firmware flash program saw it finally. I reinstalled the firmware and now it works fine. 
This may or may now work since crossing those wires could've burned the whole thing up or blown the battery up. I did this knowing these undesirable results were more than possible. However, it appears to have worked. 
If you're going to chunk yours and don't care about a possible fire/explosion you can try this.

go to rio's support page and download the drivers for it. i did this too cus my cd rom drive dont work. however when i installed the drivers it picked uip the rio player but windows wouldnt give me any suggestions when the player was plugged in. it just gave me the option to do nothing. so i have yet to find a solution for this. i am still trying so ill try to update you asap. jacob ray

my mp3 player will not come on and stay on, it keeps blinking on and off.

UPGRADER is a mode that purges the firmware from the Rio player prior to flashing the unit. Firmware is basically the operating system for the player, so if it is corrupted any number of things can occur. You can enter UPGRADER mode to update the firmware on your player by holding down the MENU button when you power the Rio ON. Flashing the player in this mode erases all content. Try the following to get the unit out of UPGRADER mode, if powering OFF the unit will not correct it. ALL PLAYERS - If you accidentally entered UPGRADER mode, turn the unit OFF and then back ON again. - Download the latest version of the firmware for your player and upgrade the unit. Visit http://www.digitalnetworksna.com/support/rio - It may be necessary to run the firmware update more than once. - This process may erase content from your player. - If the player is detected by the computer, it is recommended that you format the player, which WILL erase content from the player. - Macintosh user's try flashing the player on a PC. FLASH MEMORY PLAYERS - Remove the battery and replace it, this will reset the unit. The Rio Forge, Rio se510, Rio Cali [Black Rio Stick], and Rio Chiba [Black Rio Stick] can lock up causing the player to be unresponsive. If this occurs there are two things that need to be performed to resolve the issue. First you want to remove power from the player this includes the battery and a USB connection for 20 minutes to reset the player. There is a capacitor on the player that stores a charge that holds the player in the locked state. By waiting the duration the capacitor will discharge and the player should function as normal. Second you will want to upgrade the firmware to the latest version and format the player to prevent future occurrences. HARD DISK DRIVE PLAYERS - If you have a Carbon, Nitrus, Eigen, or Karma, use a paper clip to reset the unit. Your Rio will power off automatically when it has been reset. It may be necessary to connect the player to AC power and then reset the player if it will not turn on. If you are still unable to have the player exit UPGRADER Mode, then try it on another computer. UPGRADE FIRMWARE - Connect to the internet - Go to http://www.digitalnetworksna.com/support/rio/ - Click on the appropriate player - Click on the FIRMWARE tab [showing by default] - Click on the latest firmware file [example: RioForge_firmware_133.exe] - Click SAVE when prompted - From the SA
