To Hkan - Thank you so very much for all your work with the Pioneer players firmwares. Three months ago, I've bought a DV-420V with firmware YKB9326C and upgraded to your firmware and it has worked wonderfully. I really like the new logo and very thankful that I can now see the whole filename of the movies.
To Finn Femfel - Thank you for sharing your experience with your upgrade of Hkan's recently firmware toward the new 2010 model having firmware YLH0319A. I've just recently got another DV-420V for my dad, and this one is the newer 2010 model with firmware YLH0319A. Unlike you though, I stupidly went ahead and try to upgrade using Hkan's current v2.3 firmware meant to be used on the 2009 unit. The player can power on, and the dvd tray can open, but it will not close. When manually closing it, I also got the "no disc" message.
I've taken some time to gather the parts, learned how to solder, and put together the 3-wires serial data cable shown on Hkan's page. I don't have the original YLH0319A firmeware, so I have used the YKB9326C_uncut firmware from Hkan's site. It took me several attempts.
On the first few attempts, I've noticed that the HDMI led light on the front panel stayed lit on. After the upgrade reached 100% and finished, I tried to power on the player and it won't power on. It was still dead.
On one occasion, somehow the HDMI led light on the front panel was off, and after the upgrade reached 100% and finished, I tried to power on the player and it power on, and it has the word "WELCOME" on the led display. Other than that, it won't let me proceed to do anything else. The DVD tray won't open, and it won't even power off after pressing the power button again.
Hkan and Fin Femfel - I'm wondering if any of you wonderful folks have had any success in extracting/obtaining the new YLH0319A firmware?
If any of you do, may I ask for your kindness in posting it up or sending me a copy so that I can try to revive my dead player? Thank you and best regards!
