Installation

Prepare the card as usual, dumping the appropriate version (Regular or speed reduced) into your card. Firmware file will be replaced.

********WARNING*********

USERS OF FlashAir CARDS are advised to perform ALL file copy operations locally on their PC/MAC and NOT over the air.

*******IMPORTANT NOTES**********

  • If you’re a user of a Perixx PS/2 keyboard or a keyboard with a similar controller (ie certain Lenovo PS/2 keyboards) you may find yourself after upgrading without a functioning keyboard. In that case locate the [AlternativePS2] section in your config.ini file and switch it from 0 to 1 or vice-versa
  • Default config.ini settings assume an HDMI monitor. If you’re using a VGA monitor you should delete your config.ini file located in c:/tbblue/ and replace it with the config.ini.VGA file (also located there) renamed to config.ini

Flashing the new core

1. For people with functioning keyboards after boot and/or membranes (but which also have PS/2 keyboards)

Let the machine boot normally, then press and hold U on your PS/2 keyboard, then tap momentarily on F1 (still holding U) and release U when you see the updater module. Press Y, wait until all flashing is completed, then power down the Next and REMOVE ALL CABLES. Wait a little and then plug everything back up again. If you have a VGA you need to replace your config.ini (see above) or edit it and set the second number after the machine type to 0. If you’re in Brazil, Japan, the USA or Canada or any country that uses normally an NTSC TV signal (or a PAL 60 signal), chances are your monitor only supports 60Hz, so go ahead and tap F3 now -or alternatively you can change the [50_60] setting to 1 from config.ini or by editing the settings at boot time with the EDITOR module (Press SPACEBAR when prompted on boot then press to edit your settings)

2. For people with Perixx PS/2 keyboards and/or keyboards with a similar controller on board AND people with membranes that are not functioning or having trouble entering the UPDATER module.
  • Enter AntiBrick (AB) mode by removing all cables (including HDMI), pressing and holding M1 and Drive (simulaneously), then reapplying power (no HDMI or VGA yet) waiting a few seconds (2-3) and releasing the keys, then reconnecting the display lead that worked for you previously. Press Y for update. If Y cannot be pressed then the press M1 button for or Drive button for N
  • Once the flashing is completed and before booting, take your card to a PC, edit the config.ini as described in the Important Notes section above to enable the alternative keyboard controller
  • Follow the instructions in Step 1 to boot the system.
