Opened A Xbox To Find A Hitachi-lg Dvdrom, **MERGED TOPICS** Options

[akzim_inahurry]

Are you sure?
Did you test all type of supports?
Wich diagram did you use?

yep i'm sure tried a platinum 52x cd-r, a phillips 10x cd-rw, a platinum 8x dvd+r, a princo 8x dvd-r and a phillips 2,4x dvd-rw and all could be read(always burned on full speed).. just used the diagram which was posted before in here for soldering.. dont see any problems with that drive.. works fine..

greets

Wich firmware did you use?

Thanks.

Excellent work everyone. These last few post force me to ask this question. Is the 8050 media challenged as a result of the firmware or the hardware? From what akzim_inahurry would have us believe an 8163 moded reads cd-rs without trouble. Which means the hardware of the 8050 is the problem. But I had always believed the firmware was the trouble. This should be investigated. Who else has moded an 8163? Could you guys report any cd-rs that work? I guess, if it is the firmware, I think it would be convenient if there was developed a firmware to patch the 8050 so soft moders like myself could avoid opening the xbox in order to get cdrs to work correctly. Somehow attempting to maintain the ability to return or replace the xbox through warranty or whatever. (Electronics will often die on me.)

Hi there!
I don't want to be a pain in the a** but what about the spindown issue when pausing a video DVD during a few minutes.
If someone who has a modified 8163 doesn't have this problem can post a scematic of the soldering as well as the firmare used, I'd be gratefull

I have the points soldered and the drive flashed with the correct firmware. (Unless there was a problem with flashing the correct firmware over the originally posted firmware.)
(does not read CDRs -btw)
The drive freezes up after (about) a half an hour. Then it won't start at all. If I mess with the connections a little, (unplug and replug the cables) it works again. (but only for a half an hour) It could also be the 10 to 15 minute delay that makes it work.

The wire i used is pretty thin, 30AWG. Could this be the problem?
Also, my soldering isn't the finest. Could too much solder cause this malfunction?

I might want to flash the drive back to its original firmware. (I think Maxamillion posted a way... not sure)
Has anybody else had problems like this?

OK, I can confirm that TruBB's last instruction post (Page 49) does work.

I originally used the mod instructions found on about page 35. It was working, but intermittently.

I had re-modded mine according to page 49 and everything is working as intended. This involved moving two wires and re-flashing.

Now that I know it works I will be ordering another drive, because the head alignment on my current one is off. It has a difficult time recognizing DVDs, it finds CDs without a problem. Too much disassembly and re-assembly I guess.

Thanks for all the great development work!

I followed all of wenid instructions (Page 35) and everything is working fine. I have two drives and neither have a spin down problem, I paused a movie for an hour and I played paused a game for 1 hour also to test. I haven't tried cd-r's yet but I doubt they work.

Not everything!!!! Because the CD-Rs don't work !!!!

Thanks everybody for the work that you done for all of us.I have an xbox 1.0 and for the past few weeks my thomson started to give his spirit away.

On friday i bought a DVD ROM LG 16X52 (GDR-8163BB) Bulk with software for 20EYRO (about 30 dollars).

A friend of mine which i thank him very much came on Saturday and after 1 hour we had a working 8050.

Thank you very to everyone and especially TruBB.Also thanks for the firmware on Xbins.

Everything works like a charm.Every game.3 different types of DVD-R TY02,Princo,TYG02.DVD-RW also and cd-rw.

I didn't try cd-r.

Evox status ok , Open , Close, Init Correct display status.

Also Avalaunch report the DVD as 8050

So again THANK YOU guys

P.S. I will try the DVD movie spin down problem and report on evening

I tried CD's and worked fine

Also no problem with DVD movie spindown.

My installation besed on Truebb instructions on page 49

[liteon6x]

I just want to know before i carry out this mod ,if a resistor is not used will this mod still work and will it short out the drive if it is not present

also whats the purpose of the resistor

[panosvo]

Well i have just bought 10 drives GDR-8163B , JANUARY 2005 , ROM VER.:0L23

I have flashed them with "8050L_FW_Flasher_FIXED" and used the points from page 49 that TruBB post , and i used 3 1K resistors ,
Well the drives work fine they read copies , originals no problem with spindown or "init" but they cannot read CD-Rs , i dont know why ace1774 that i also made reads CD-Rs?

Will do more test...

The resistors are not necessary, but if you want to replicate the original 8050L xdrive, then install them. They are there so that you don't fry your xbox or dvdrom if you hook it up wrong. Hooking these lines up to 12VDC could cause latent defects in the uC of the dvdrom drive.
I suggest for everyone to install them, just to make the mod as similiar to the 8050L as possible.

[ace1774]

Sorry my mistake.Doesnt read CD-R.

Everything else works perfect

Sorry Pano.....

[9alfred7]

The firmware prevents the use cd-rs.

Why didn't M$ also prevent the use of dvd-rs?

Hi all
I have been following your developments with great interest. Here are some interesting obsevations that have been made in my experience in modding 616e running dual f/w. Some modded drives will nolonger read cd in emulation mode; however if the drive is switched to native there are no problems. The major difference between the f/w operation is the the spindle speed. The slower the spin the greater the return laser signal from the disc. CDs inherently have higher return signals than DVDs. Therefore, with CD discs running at slow speed produce laser return signals which are too strong, as result saturating the DSP circuit.
Here are some interesting specs to consider

Max xbox ROM spin is X4 to X5
max pc ROM spin dvd X16 and for cd X32 or X48

Basically there two options to solve this effect is to patch either the native f/w or the xbox one. The method that I choose was to run dual f/w as being the most expedient solution.

Keep up the excellent work!
