sorry..double post.

yup - by default it contains both versions of winbond 256kb type tsop

anything else grab the raincoat 0.501 config file and drop that in as that file has most other types that may be missing from the more common tsop types

still a tad scarey though coz you are running/flashing tsop as blind as a bat but does work well without a pc/telnet

I'd put money on it being a soldering issue. Until you've checked your soldering with a multimeter or resoldered them anyway, you haven't checked your soldering.

A VISUAL INSPECTION ALONE IS NOT SUFFICIENT!!!

then you really need to verify it with a multimeter

did you scrape the coating off the points first?

Troed in responce to you e-mail stating not to talk about things you dont know then you are wrong coz you do have to solder points on the bottom read tutorials...those who have tryed to help me thanks but still no joy unfortunatly seems mr gates is using a new winbond chip that is very hard to by pass the serial for the chip is above it DONT in in T it ends in T-90B and NO ONE seems to have the write code for evox or raincoat ive tryed 3 versions of raincoat altered all raincoat cnf. and also altered evox.ini with the information i was given still no joy the manf.date is 03-05-2003

Idiot.

Why should I read tutorials written by people who don't know what they're talking about?

You only have to connect the pre-soldered pads on the top side on v1.2-v1.5 to get write access to the TSOP. On v1.0 and v1.1 one of the pre soldered pads are on the bottom side, the other on the top.

Don't play with things you don't understand.

Hello hello, what's all this shouting? We'll have no trouble here!

Seriously though, as Troed says, on the 1.2 and newer boxes you only need to solder (or jumper with conductive ink) the top pads. The ones on the bottom of these boards are connected directly to the top ones near the TSOP, so by joining these you're only duplicating the connection.

If using conductive ink, try cleaning that section of the board with isopropyl alcohol or isopropanol (in other words, head cleaning fluid) first, to make sure you're joining solder pads and not just joining two pads of dirt or flux.

Letters and numbers after the main chip number tend to refer to chip speed (90 = 90nS) and package (DIP, CERDIP, TSOP, PQFP, BGA, etc), although there are exceptions (29LF020 is not the same as 29LF020A, for example).

Useful info can be gleaned from the manufacturers' data sheets for these chips. Handy if you think you've discovered an Xbox with a new, "unflashable" BIOS and you're starting to panic (you wouldn't be the first).

I flashed a W49F020T last night with the 007 Flash Kit.

It also had the new Focus TV chip, so I used evox M7.

No problems.

This weekend I flashed, amongst others, the following using Raincoat 0.501, same config as in the version that can be downloaded from my sig. below (which hasn't changed for ages):-

Winbond W49F020T-90B (recognised as W49F020)
ST ST29F002BT70N1 (recognised as 29F002)
ST M29F080A (recognised as M29F080A)
Hynix HY29F002TT-90 (recognised as HY29F002)

Oh, and one of them had a Focus encoder as well.

All were done by soldering the jumpers, in the case of the 1.2/1.3/1.4/1.5 boards the bottom jumper was NOT soldered.
In no cases did "Flash not writable" or the 0x00, 0x09 errors occur. If they had, I'd have resoldered.

or try the evox-hach. I updated it today.

WhatsAModchip? · « **Reply #24 on:** October 27, 2003, 03:17:00 PM »

this should do it:
Flash = 0xda0b,"Winbond - W49F002U",0x40000
Flash = 0xda8c,"Winbond - W49F020",0x40000

one of those babies, put them both in

So what is the story with the Winbond W490f20t-90b?

Tries to flash a box and gets the following error.

Have tried to re-solder both points (using the upper ones)

Have done a lot of boxes and this is the first one which I hava problem with.
Added this to the raincoat.conf but i didnt help me.

I have flashed a quite a few of the focus chip bearing 1.4's I use a conductive pen on ONLY the top two sets of points. Scraping is a must with the pen!! It doesnt take much to make a bad connection when using the conductive paint. Obviously when soldering you are getting a clean connection.

Ive used 007 on all but the winbond. And used stock raincoat.5.01 on them no problem.

Just one more thing to clarify,

The box i trying to MOD aint a 1.4 with a focus chip..
