Full Version: Abandoned Fit Bluetooth To 6000 To Make 6000w
OESF Forums > General Forums > General Support and Discussion > Hardware Mods
speculatrix
I have placed an order with Segor.de, who speak excellent English, to buy two modules for 6000. I shall fit one of them to my 6000, and if it goes well I shall offer to do someone else's... or sell the module on at cost. I shall photograph the process and post results. More to follow... wish me luck!

---- sales@segor.de said on 15th May 2006 ----

The WML-C09-AHR is available in our stock,
price is unchanged:

1-4: EUR 39,00 per piece (including german VAT)
5-9: EUR 37,00 per piece
10+: EUR 35,00 per piece

Freight charges to UK by "international letter" are EUR 7,00.

It it wasn't the complicated retrofitting procedure, i'd be interested... :/

this module is the one "blessed" by Sharp, so it should literally be a 5 minute soldering job. I've now bought some high quality jeweller's tools so am ready to tackle dismantling the 6000 so I can also look at the flash and ram devices too.

the modules arrived yesterday, VERY well packed - box was 3"x3"x5" for two devices the size of my thumbnail and wafer thin! Segor are excellent sellers - respond "instantly" to email and goods arrived three working days after placing order!

I confirm that the devices do have integrated ceramic aerial (as ordered), and look just like the pix that Guylhem posted before.

Stay tuned for more updates, and I will posting pix on my website.

sadly, it seems I was misled - after spending some time carefully dismantling my Tosa, and putting the module in place, it became apparent that the pitch spacing of the pads on the PCB doesn't match the spacing of the points on the module!

taking the Z apart wasn't too hard, but to get to the space for the bluetooth module means a total strip-down, there's practically nothing you don't take apart!

yes, these are the things that slow down my wanting to mod my Z! I applaud your courage and effort smile.gif

If it's not C09, then what module is it? Somehow, I think I've heard about C19, would it be the one used in 6000 series?

OMG! Disaster! I was taking more photos, to measure the pitch of the connectors and the bluetooth modules... when I was reassembling it and putting the wifi adaptor back in, I accidentally pressed down on the other side of the board and snapped the end of one of the Samsung K4S561633C devices, which is a BGA. I carried on putting it back together and prayed the damage was cosmetic but my 6000 is dead as a dodo... not even the OK memo will come up.

Looks like it's completely ruined. I could cry. If it were a TSOP or something replaceable, there'd be more hope. As it is, I think I've reduced my Tosa to a collection of scrap parts. I'm stunned. Can't believe I'm writing this.

That is a real bummer.

Looking at the data sheet it is only 6 X 9 pins. It probably could be repared if you could get one but it won't be easy.

I took close-up pix showing that the C09 is hard metric pitch, the PCB is definitely not. More at some point - I'm still working on fixing my file server whose hard drive died in the week meaning I'm rebuilding from scratch and restoring from backup!
albertr
Ouch! Sorry to hear about your 6000 disaster... Hopefully, the damage is only the DRAM chip itself, and not the CPU's memory controller. If so, it can be repaired by replacing the BGA chip, just reseach the local shops to find one that does it affordably.

It's definitely the dram chip - I can see a line across the surface denoting a hairline fracture.

Even so, I rebuilt it and hoped at least to get to OK prompt, meaning that the lower memory block is working, thus allowing me to do some sort of hack to get Z to boot with just half the memory - assuming that the PXA255 has a 16-bit memory bus. Sadly, no, no sign of life at all.

That's the samsung page on it, if that helps. I haven't been able to trace a distributor yet. . .

very useful link, thanks - I've been reading it.

The original K4S561633C-RL75 has been replaced by equivalent K4S561633F device, which are 4 x 4M words by 16 bits (i.e. 16M x 16 = 32MBytes).

I am wondering whether I could use the K4S511633F which is 4 x 8M x 16, or 64MBytes.

On the other hand, there's space for FOUR devices in my Z:
6000 ram chips
so *IF* it'd take 64MB devices, I could have a total of 4*64 or 256MB ram in a 6000 - which would make it pretty l33t!

(pic taken before I snapped one ram in half).
Ferret-Simpson
It would be good, and would also mean that your Z would work again.

Heh, I'm a fixer at heart, so no problem! Besides, i owe you for your pesistance in helping me with my N00bish inability to make a GPRS connection work.

You should call up those distributors and ask them about parts, anyway. Even if they ask for a minimum of 100 chips, or something, It'll still be cheaper that £400 for a new Zaurus, and you can flog off the spares to other people with problems.

OR make an Open Source PDA. . . . wink.gif
speculatrix
ok, so far... some only sell complete modules, some only do trade orders minimum 1000 pounds. my current hope is with Future who have no stock but might be able to get a small batch.

will edit if I hit gold.

meanwhile, someone on the forums who has successfully done BGA re-work on zauruses (I won't say whom as he might not like lots of people emailing for memory upgrades) might be able to help, so there's still hope!

back on to the topic of WML modules... comparing the spec sheets of the WML-C09 and the WML-C19 devices, the spacing on the connectors is quite different:

WML-C09 Spec PDF
WML-C19 Spec PDF

Having mostly recovered from a major disk crash a fortnight ago, I will soon be uploading pix of 6000 dismantled and this should show the precise connector pitch.

Hello

Since I'm at fault for your Zaurus misadventure (I just didn't measure the exact spacing on the chip - it was looking identical to the WML), let me know if you want me to send you a spare 6000 motherboard. The display connector is dead, and the fuses have been replaced by shorts, but you could certainly use the ram chips and everything else. It works fine in a 6000 without display.

Sorry,
Guylhem

that's very decent of you! I undertook the modification fully in the knowledge that it was risky, and I still think I can use the WML-C09 modules even if I have to use flying leads... breaking my 6000 was pure bad luck and/or incompetence on my part.

I've got two promising options at the moment, a key one being a well known OESFer (I wont say whom as he/she won't want inundating with requests to mod zauruses) who might be able to replace the BGA devices for me... if these fall through I will take you up on your offer, but in the meantime don't be discouraged - if we can pioneer zaurus upgrades and make them easy to do, then maybe we can foster a generation of upgraded zauruses and thus gain critical mass for people to develop better software for them!

Once it's working again, I still intend to upgrade my 6000L to a W, when I know for sure which module is literally plug and play!
guylhem
Thanks - I'm sorry of what happened. I should have been more cautious as well. [the dead display connector on the motherboard I am offering is my fault :-/]

Heh

Do you think we should do a mass grave for dead Zauri? We could put some form of statue up, in the shape of the OpenZaurus dinosaur.

"Here lie The Collies, The poodles, and the akiti, the tosas and the Spitz'. We shall treasure their memories, and the bits we nicked off 'em, forever."

Goodluck on both getting bck up and running! ^^
speculatrix
in case anyone wondered what happened in the end... I bought a part dead zaurus and swapped motherboards. I had hoped that a friend of Anton Maslovsky could fix the ruined motherboard, but it wasn't possible. So, I have one mostly good and one dead 6000. I still hope to get it repaired, if I could remove the ruined ram chip (dremel?) and clean up the board, I might then find someone who could fit the BGA device, if I could buy one.
