you also can use special FW upgrade procedure to eleminate "stuck in FW upgrade".
By this procedure you can delete the "FW error flag" and get back original error screen without "FW error****, 0801"
e.g.
1. FW upgrade during C6950/ F040 error message
2. system stucks in "error IH pwb, 0801", "mail bin error, 0801" or else...
3. upgrading from CTRL(main), ENG(engine) + Panl(panel) only
4. C6950/ F040 error message again, no more stuck in FW error after restart
5. Exchange from low voltage pwb
6. running complete FW upgrade without ES_Skip.on file
7. Done, system repaired, no more error.
See enclosed sample leaflet.
(Also works on other systems like Alphard 1, Mercury, Tomcat, but won`t work on Iris series, because "FW error flag" would stored on SSD PWB instead of HDD or operation panel!!!)
