We decided to make a video on how to remove the "black epoxy" and two methods to desolder the TSOP flash on new Hitachi 0078fk drives.

This black epoxy (not glue) needs a higher temperature. Anything between 100-120°C is ok.


now enjoy it!

I need a programmer, some adapters, and a pyro pen.

AGREED!!

all I can find so far for a pyropen is by weller seems to be 2 types one being a junior.

However they say they blow a TORCH which I do not see on the video and cant imagine using a torch.


Textbook did you find anything?

That is an amazing movie. Haha I wish i had those kind of "skillz"

I get it.. it is all in the tip. you have tips that are torches and tips that are hot air.

i wonder if a programme will come to be able to flash the latest hitachi drive before i have to learn thease skills

I have removed and replaced many 48 and 56 pin tsop chips this way, once you get the hang of it its easy. A great hot air (pyro pen) for 29 quid or 39 for the full kit is available from maplins. Irodo solderpro 120. and if you want to program the the chip in question you will need a "14mm 32pin tsop adapter suitable for the programmer you use) these adapters are a miniture version of the tsop adapter, do not get a normal 32pin tsop adapter. And make sure you have a programmer capable of programming a 39lv020 chip.

Hi Ice-9

Found the pyropens you mentioned here
Would any of those pens/kits do the job or would it HAVE to be the 120?

Any chance of a link to the best programmer & adapter too?

Cheers

You could use the Solderpro50, I have. Also search eBay for the willem programmer 4.5 with 14mm tsop adaptor.

how does he solder it back to the board? How does he remove the solder? Jeeze that's amazing.

I practiced this last night with a crappy broken down dvd drive (not a 360 drive)

Not the epoxy just removing the chip.

I did just as the video did....

A good soldering iron helps alot..
put a line of solder across the legs on one side....

then take exacto knife and put pressure on one side while taking solder iron and running it through the solder back and forth back and forth.

I only have a 15watt soldering iron.. I suggest using a slightly higher wattage because 15 seems a little low to warm up the whole line of solder quickly enough.

anyway finally you start to see the legs lift from their pads...
do the same to the other side... and boom its removed.

clean up the solder from the board very easy.... then with barely any solder on the tip just graze the pads left behind and they will be shinny which means they are tinned ready for the chip to be put back on.

the chip has very small legs and you need to clean them up also when removed... again just drag the dry soldering iron across them ever so slightly and the solder will come right off the legs.

becarefull not to bend the legs when removing ... make sure they are flat again before putting back on.

put chip back on tinned pads...

line them up (magnifying glass helps alot) line up the connections by tapping each corner leg to align properly otherwise if you start with one then go around in order it will more than likely move by the time you get to the end of one side.. causing miss alignment.
once tapped down.. tap the rest of connections running soldering iron down the legs not perpendicular but the same direction the legs are laying down.
you really do not need solder on the iron for this since you left the pads tinned.. so your solder really if done right should not cross legs. thats why I did not go across the pins... rather move iron down the pins.

tested with multimeter and all connections were good!

now for a programmer... thats another ball game and is quite expensive


the person in the video makes it look VERY VERY easy and is amazing..however if you practice enough its not that hard.




Make sure you read about the pyropens... I have found alot do a torch (flame) which is not what you want... it seems it depends on the TIP you use for some. So when you purchase one.. make sure the tips that you get with it do the HOT AIR way not a TORCH! just a suggestion.

do these wiliems work? can't seem to find any that specifically say 4.5

27C256 & Enhanced Willem EPROM Programmer BIOS FWH MCS
27C512 & Enhanced Willem EPROM Programmer BIOS FWH MCS
27C32 Dual Powered (USB/AC) Willem EPROM Programmer
27SF512 & Dual Power Willem Universal EPROM Programmer

all of these are about 40$
but there are others that are 100$+/-

could someone point to what they KNOW for sure would work on ebay? Keep in mind pricing for some of us. No need to spend 100$ if the 40$ will do it.

In the video in this thread he uses a pyropen like a blowtorch, im sure i see yellow flames.

Can the samsung have the black epoxy?

No need to remove it on a sammy unless you need to do the VCC trick or fit one of those useless modchips.

So there is no point for a dual firmware anymore? Since all the stealth stuff?

Definitely some soldering skills there.. To those who don't want to invest in a pyropen.. you can use your hot air gun (It gets more than hot enough to melt solder...) in a similar fashion; just use several layers of aluminum foil to mask off the surrounding board area so you don't end up accidentilly desoldering/melting things you don't want to.

Wow those boys are pros. I'd be so terrified of melting chips.


Another sweet vid from these guys. Thanks!

Damn fine soldering skills there. I wouldn't have a steady enough hand to tackle that.

What will M$ do next? Titanium enclosure welded shut with poisonous gas enclosed to kill anyone who opens it? Better not give them any ideas.

SHIt i dont even give a shit about the point of all that.I was just blown away with those skills(i cant even keep my hand steady).

MUHAHAHAHAHA

God vid XM but the average user will over heat or use too much pressure on the board and damage it.
I reccon average joe's should not try this unless you have cash to burn!

I have a friend that bought this. Cheaper than s Pyro Pen with great results. Im saving to buy one. Its a must have for those electronic projects.

Nice Video.

Nice vid. one problem there though.

The vid indeed starts with an 0078 drive, however once the TSOP removal starts the board has been swapped for an earlier version of the Hitachi Board. The reason that this is important is that underneath the flash chip on an 0078 drive more epoxy is placed probably before the TSOP is placed and then reflowed.

This epoxy underneath the TSOP is always there and consitently in the same place, ie on the ground plane. therefore the TSOP removal takes much longer than in the vid and much more troublesome from a point of view track/pad damage. It is possible to do, as I have done a few without damage.

I am not having a go at the vid it is nice work, i just think it could be a little misleading for all the noobs that are going to run out and buy a pyro pen and more than likely trash there dvd controller board very quickly.

I was thinking the same thing when I watched it. I remember reading about the epoxy being underneath the chip as well. Then, he pulled that one up and there was nothing under it. I agree that part is slightly misleading, but at least he showed how to remove the TSOP.

Those vid files are Great , i'd like to be able to save these to my computer , is this possible via YouTube ????? or do i have to keep my fingers crossed that they will never be removed ? would be nice to have them to hand if and when needed.

I had removed the black epoxy before this video came along but its a good tutorial. Now i just need to find a working hacked image!!

how dose he get the solder to stick to the the iron. solder just runs of mine (cheap 15w antex iron)

Before I start seeing a load of people asking for help becuase they killed there drive attempting this, although he makes i look easy, its not. You can have all the right tools and still f**k it up, so before you go out and buy tools understand that it was done by professional, this is not for everyone.

You need to clean your solder tip, or re-tin it using solder flux paste or similar.

if i tryed that the chip would probably explode. Im still gonna try it.

I used a SolderPro 50 with heatblower attachment. I'd consider doing the direct solder blob method but I'm a little unsure as to how to clean up the bridged TSOP legs..

Scary as fook in here.

quote: 'How do I get solder to stick to my iron?'

I dont build Houses and never would, nor will I try, I dont try and put a new engine in my car when its blown and will never try.

Stick to your knitting simple as that, regardless of this vid if you are not VERY experienced and at least experienced at soldering 0.5mm legs on IC's to rebuild the damage you will probably do, dont go and buy a poor excuse for a hot air station in the form of a cheap ass weller pyro whom incidently make the most unreliable poor ass excuse for a soldering iron known to man. Handles get hot, heater burns out etc etc.

I dont mind the DIY philisophy but I fear this is taking it an expensive step too far.

Earlier in the thread someone asked where to purchase Willem programmers. I bought one two months ago from http://www.sivava.com/ (in Thailand), version 4.5(B?) with a bunch of adapters thrown in, including the TSOP 14mm/20mm. For about $40 + $20 express shipping (not bad for 5000 miles).

Just a FYI for those interested. Works on most PC BIOS (why I got it). Component quality and construction far better than expected. Good buy.

Stupid question I am sure here.. but I do not have a 78 in my posession and am wondering what the number of the chip is??

well do u know of any compatable programers. i dont care really about price im more then willing to make the investment so i can do somthing like this. thanks

Here is a link for a firefox extention that allows you to save youtube and google videos. Hope that helps you.

The programmer needs to be able to read/write to a 39lv020 according to a previous post. I have a labtool clone which will do it in seconds http://www.jabsplace.co.uk/shop/index.php?...d568b9213482f06

I have looked at the vid and am ready to try this I have a hot ait rework kit seems to pull chips off the board very nicely but where I am stuck is the external progamming itself there seems to be no guides on external programming or injecting the key into the hacked fw how do I do this?

quote from Maximus.Xtreme.1_5.for.Hitachi.v0078.REVISION2

Dont forget to put your keys onto it before flashing
(you can use firmware toolbox 1.2 or hex editor)
Dont forget to crypt the file before flashing

crypt? can some please explain in more detail for us sub-noobs

cheerz

Nice video, does not change much from the white epoxy...

btw, the music is not by Jean Michel Jarre!

Cool vid. A few more items to add to the toolbox. It's a great thing working in the IT world. When you want to learn how to do something, just pull an old one out of the stock room. practice, practice, practice.

all you have to do is press generated encrypted file in firmware toolbox after your replaced the key

has someone actually flashed and run a backup with this drive?

ALDI do the pyro soldering kit about £20.00 butane is under £2.00

the vid is removed

somebody stored the vid on his drive ?
