Release Reasons:

1. Combine PLUS, MINUS & DL+R writing capability into one firmware
2. Support more DVD+R & DVD-R media.

Great that they did it
...i've it not tested yet.

Works great on -r and +r but no dl to test on yet. Very happy here. Now, Dangerous Brothers patch this rpcII for us alright?

Check this out



..thought, there´ll never be a time without SwitchTool ...

CoOoOoOoOoOoOoOoOoOoOoOoOol.
Finally.
Now, Dangerous Brothers patch this pleeeeeeese for us alright?

anyone try this on dw800?

will DL work on it

Oh wow! Sweet! Now I am impressed with BenQ - I thought we would never get beyond the switch tool

I wonder why they didn't enable QScan for the new firmware - I don't think the drive has to have some special features for the QScan magic, I guess it's all about firmware...

yes it does, but flashing to 822 fw has cause problems for some

Can you elaborate? What sort of problems?

It's just a hit or miss. 800a's laser (using doctor evil from austin powers quote with my finger)may be be good enough for DL but no problem with single layer

hi. how can i downgrade from B3KC to B3IC or even better B3HC? i'm having some troubles...

If it won't cause harm to try, I'm game. I'm willing to risk making a DL coaster to see if it will work.

Did you figure this out yet?

Make sure your drive tray is empty. Flash at your own risk!

Go to http://dvdpro.club.st/firmware/BENQ_FW.htm, download WinDWFlash.exe and the b3hc.cvt file, run WinDWFlash.exe, select your BenQ drive, click the "Select flash image" and point it to the b3hc.cvt file, click the "Flash the drive!" button.

That should work.

Here is my result with TDK DVD+R 8X (RICOHJPNR02) and my "DW800A":

Now a quality scan of the disc:

Btw: for what I can seen, it's a very fast burner and with great quality. My Nec 2500@2510 has also great quality burns but it's slower because it starts the 8X burns at 4X then goes to 6X and finnally about the 2GB starts burning at 8X. On the other way, the burning graph is much more smooth because the speed drops occur only when it changes speed (just 2 times) and not all the time like the benq.

Mustang > Looks like a good burn but due to CPU usage i'd use this instead > http://www.cdspeed2000.com/ Better program to use (free) and run disk quality under the extra drop down for already burned disks at 4x or 8x

well i already have a 800@822 using b3jc fine so i justed wanted to flash it

gonna do it later now that i see some ppl have done it

Downloaded the firmware 3 times but kept getting a CRC checksum just before I flashed. It ask me if I still wanted to continue, I tossed a coin and said yes :-) Running great so far on my CD burns, no DVDs yet though.

hmmmm - using current Nero only offers 1x/2x/2.4x for Ritek 8x -R . . . . . . . not exactly what you'd expect to see when the f/w 'supports more media'

I have problems with Fuji003 DVD-R 8x rated Philips discs.
They are not supported at all and with nero only available speed is maximum.
When I burned a disc it burns at 1.2 - 1.3x and the disc can not be read.
Can someone try Fuji003 discs?

. . . never thought I'd be happy to see Q-Switch . . . WinDWflash plus B3HC.cvt did NOT work for me; but happily B3JC-2 did . . . . would advise extreme caution with this new B3KC f/w . . . I switched back after Ritek R05 wasn't recognised properly (see above) & produces a poor burn w/ PIE at over 200 ave & then some crap media took 1hr 50 minutes to burn (set at 2.4x), & was unreadable. All this w/ a genuine 822A.

actualy the cpu usage has improved from what it was and if you minimize the graph the cpu will be almost none existent.

thanks for the reply. i already tried this way but i always get crc mismatch error. i will try again when i'll have windows available again. maybe i'm using the wrong flash tool?.
i know that if i flash it again with b3kc i get a warning (it says that the loaded firmware is newer than the ona i'm going to flash) which i can skip, but at the starting of the flashing procedure i get a failure of some kind... same thing happens with other firmwares, always a failure or a crc mismatch.
i also downloaded the dos flashing tool, and i got a failure with that too...

i'm going to explain why i want to downgrade, maybe someone has some idea... (sorry for my bad english.)

i have a philips DVDRW824K/20, original firmware 2.2 (with +r AND -r writing support)
i flashed it to b3hc and than to b3ic. than i was able to flash it back to philips firmware 3.3. than i flashed it to b3kc, but i'm having problems with -r burning.

the reason why i switched so many firmwares is that i was very disappointed with the burn quality with -r media, and even more with the reading of the burned media. i gave it a try with a windows+nero setup (i don't use windows on this box, had to lend a hard drive from a friend), but with not much better luck, so i flashed it, and several time, because with any firmware i had problems. sometime i couldn't read reliably, sometime i couldn't write, and so on... with this firmware i'm apparently able to read and write with good quality +r media (more tests needed), but i can't even start a burn on -r media.

i can probably go on with only +r writing support (if reliable...), but it is a bit disappointing.

why b3kc cvt is so small? is this the correct size?

2,1M B3EC.CVT
2,1M B3HC.CVT
865K B3KC.cvt

It's small because of how it's packaged, BenQ had to change the packaging because newer drive models only have 2 MB of RAM, and it is impossible to hold the entire firmware in RAM without displacing the heap and stack required by the software on the drive.

There are a number of CVT files on JetStudio's site that are not correctly formed, and the DOS flasher will report errors with them.

The following is a 2 MB version of the CVT. http://tdb.rpc1.org/original/822AB3KC.ZIP

An RPC1 patched version was posted yesterday http://tdb.rpc1.org/#DW822

Is there any trick to getting this to work with an 800a?
I'm currently 800@822 b3jyc

I used 800@822fw_Patcher.exe to patch b3ec and get to 822
Then I just updated with the stock fm's to b3jyc

I'm trying to use the new b3kc but can't seem to get it to go

First it reports that it's an older version than what I am using
If I say OK anyway it attempts to flash, but fails a fraction of a second after it begins. No damage seems to be done, and the drive remains at b3jyc

I also tried b3kcRPC1 with the same results.

Any thoughts?
