Have I bricked my modem??

[farkkraf]

Hi, I'v been trying to reflash my cable modem. I managed to unlock the console using console unlocker, then used softJTAG and put bootloader 2.1.6d on it. When I used hyper terminal I managed to get the p option and got to the part where you type in 250hack_dump_telnet. It would not connect to this so I pulled the power out of the modem, I redid the steps and had the same problem again so I pulled the power again, when I went to reload hyperterminal again it would not connect to the modem, just had a blank screen. Iv tried to use console unlocker again but it says its unlocked and I have tried to use softJTAG but it just says "ERROR: Unable to connect to modem". The power light is steady on the modem but the ethernet flashes. I am thinking I have bricked the modem but I'm not sure as it only seems to happen through softJTAG from what I have been reading. Can anybody help me sort this out? Thanks

My modem is a AMBIT255 aswell

Connect the modem by max232 open hyperterminal and connect power to modem.

If no output, modem is most likely bricked.

Thank, think its bricked then. How do I go about sorting it out. I know you have to do a tsop lift but do I need to replace the tsop with another one or just take it out and put the same one back in again?

You'd need a steady hand, good soldering skills and a SPI/Willem Programmer (bout 20 quid). Keep the same TSOP by the way.

Or send it to Bad_Ad and he'll fix it for you.

I don't know, but you may be able to get test clips to suit that TSOP and program it without removing it. But that works out to the same cost as a new flashed modem!

I bricked my 250 had to send it to bad who sorted it out a treat.

Ahh, so I have to remove the chip the reflash. Thanks, you've been really helpful

SPI Programmer is for ambit 256 only, for tsops the cheapest way is a willem (around 20-25 quid) + 8/16bit tsop base + tsop 48 header (approx £30-35) if you want to unbrick moto's (intel tsops) you require the 16 bit base which is around £20 without the tsop header as you can use the one from the other adapter.

There are test clips for tsops, but they are specialized equipment and cost around £300-400.

then you need the skills to lift and replace tsop without damage.

As I said, this is the cheapest method... ive just replaced my old willem with a new USB one + adapters which has run me for £280.


Anyway, back to the topic at hand, yes the modem sounds bricked.

Thats a little pricey, think its cheaper to buy a new modem as I would only be using it for myself. If I were to send you my modem would you be able to unbrick it for me and how much do you charge for the service if so?

Ive replied to your pm regarding that.
