Editing Aruba AP-225 (section)

== Flashing process ==
What you'll need:

* Cisco flavored serial rollover cable, RJ45 to DE-9
* optionally a serial -> USB adapter
* a TFTP server
* 30 to 60 minutes
* the firmware images. The firmware is downloadable through [https://networkingsupport.hpe.com Aruba's service portal], but you need to go through various steps and hoops to create an account there. You can ask {{U|Nik}} for the current firmware.

 - Connect AP to a serial console with a rollover cable, settings are 9600 8N1
 - At the "apboot" prompt, stop the autoboot process by pressing enter: <code>Hit <Enter> to stop autoboot</code>
 - Set a country code:
   - generate a SHA1 hash of the country code + serial number of the AP:
     # on macOS
     $ echo "DE-CNBHHMV57F" | shasum -a 1
     31b4fe935816bd03af2388dd0485640c316d9393
 
     # on Linux
     $ echo "DE-CNBHHMV57F" | sha1sum
     31b4fe935816bd03af2388dd0485640c316d9393
   - set the code with the command
     <code>proginv system ccode CCODE-<country code>-<hash from before></code>
     for example:
     <code>proginv system ccode CCODE-DE-31b4fe935816bd03af2388dd0485640c316d9393</code>
 - then, run the following commands:
   # unlock the bootloader or sth, idk
   <code>invent -w</code>
   # get an address via DHCP
   <code>dhcp</code>
   # set the TFTP server IP
   <code>setenv serverip 10.23.92.185</code>
   # flash the two OS slots with the Instant OS
   <code>upgrade os 0 ArubaInstant_Centaurus_8.6.0.24_89728</code>
   <code>upgrade os 1 ArubaInstant_Centaurus_8.6.0.24_89728</code>
   # reset all settings
   <code>factory_reset</code>
   # save the country code and boot image names
   <code>saveenv</code>
   # reboot the AP
   <code>reset</code>
 - Done! :3
