This is not my work and is simply passed on as i successfully managed to do this! This is in my own words
however and would like to personally thank the people who made it possible!

I recently found out i had an Toshiba Samsung ms28 and mtkflash has problems reading or flashing these drives with the new revision. Luckily the lads at another well known forum helped out and now i wish to share what i have learned!

Error problem

IPB Image

You'll need to strip the dvd drive open and take the controller out!

You notice the big SST chip and just to the right is the vcc resistors, you must remove the resistor in the
middle as the pic below shows already done. Then you must connect a wire to either blue point and a wire
to the red point. You can purchase a simple on/off switch to make this operation better but is not required!
You can simply put the wire ends together when needed.

IPB Image

After doing this and you now have removed the resistor, attatched wires and maybe an on/off switch
should have something looking like this!

BACKING UP THE KEY AND MS28 FW!

Assuming your sata is detected and everything is working etc Boot into dos, but make sure your wires are
not connected to each other, or if using a switch it is turned off. Go to where your mtkflash is and
type the command as you would usually for the normal method to backup the key but dont hit enter yet!

I.e Mtkflash r /m ms28.bin

Now either join the wires, or turn the switch on! hit enter on the keyboard and you should if done correct
see the ich5 channel or whatever sata port is used. Hit the option for your drive and it should be now
successfully reading the drive and not giving the error as before!

FLASHING YOUR MS28 DRIVE

Word of caution here, KDX will not work with reading and injecting the key out of the file you backup!
You can hexedit the file you backed up and notice from the 4000 mark onwards is a c0 then followed by
your key which is followed by FF's. You can copy and paste the key into the xtreme firmwares you have
already be it the 1.2 or 2.0's and then flash the firmware as normal.

Dont worry about the hex editing! its important to get it correct of cause but your essentially doing the
exact same thing as KDX and copy pasting from the backed up file, to your xtreme.bin etc

Ok so once you have managed to hexedit the key into the xtreme.bin you can now reboot back into dos
making sure the wires were disconnected 1st and ready to redo the flashing stage same way as backing up.
You cannot boot up with the wires already in joined as the sata detection may cause a prob and wont detect it in dos or at the mtkflash stage!

Assuming you have got the wiring still correct and nothing moved out of place, you can now execute the command to flash! i.e mtkflash w /m xtreme.bin

Tools from maplins

1. 12w soldering iron 14.99
2. 30 gauge wire 1.14
3. On/off switch single pass through 1.30

Many thanks and happy to give back if this helps anyone!

enjoy this is confirmed working by me and others!

regards

No there is a new replacement for the samsungs it seems!

The ones available in the masses at the moment are the ms25's which work with no fuss!
However this is a new wave of drives and a new response to xtreme firmware!

These will become more popular, so the quicker people learn this the better!

Didn't take too much and isn't that risky! get a 12w soldering iron and 30 gauge wire!

thanks

All you do is put the wires on the points after removing the resistor! they act as an on/off when joined or unjoined! anything in picture that looks heavy is probably just the pic! you dont touch the SST chip at all!

Dont worry about any epoxy or anything like that! thats how it is already!

We could see other revisions but utlimately the drives are the same hardware!

On the sticker you'll see at the bottom

FW=ms25 or FW=ms28

there has also been other versions previously like ms07 and ms19!

They have never changed the hardware though! meaning there should be a little way round any they do!

May i remind people this is not my work and is purely put on here through my eyes after it worked!
I dont wish to take any credit other than for this simple tutorial put in 1 place!

Redline at XBH showed me this last week. There is another method to try, which doesn't involve any soldering...


Basically, just go about flashing your samsung like normal. When you get to the part where it asks to press 1 or 2 for Master or Slave (just before you flashthe drive), turn off your 360. After it powers down, press the correct channel button. On screen, it will look just like a normaly flash, but it will be in pause mode, waiting for a response from the Sammy drive. After having the system turned off for about 10 seconds, turn it back on. Now that the drive is on, it should flash immediately. This is also known as the Flash Recovery for Sammies. If this doesn't work, then try the VCC trick. This is nicer and safer for those people who aren't skilled with soldering techniques.
