Cable Modem gone down in my area.

[dark-ripper]

Excellent sounds like the way forward. Still have yet to sort mine. Going to be doing it this weekend now, as i have no spare time at the minute. Will let you know how the alternative options go. But the lad on ebay sounds like hes got it right.
Cheers for letting us know about him Alex.

no fix for bricked modems. cant reprog chips
not all flashed modes have gone off

[dark-ripper]

Hi all. This is latest i know of regarding these damn modems. If you can access your modem via your command centre, get the password and login changed, then lock the frequencey to 23, and you should be ok. For all those who can't access their modem, your gonna have to reset it manually through TSOP. Once you have sussed, you may have to refl*sh the firmw*re (Doesn't need to be done with 255's as far as I'm aware) once this is done, you still going to need to change the log in details and lock the frequencey. Hope this helps.

is there a way to put original firmware on a 250 with infinate ? on original firmware is the only one that works

[lincsat]

I have infinite working perfectly here. The MAC's and serial numbers are setup to match and the telnet login has been changed. It's been running for 2 Weeks now without a hick-up

HELP!!!!

******(this is info i pulled from another forum)******
Virgins attack cloners head on. New modem countermeasure the encypted configs
--------------------------------------------------------------------------------
Across the country slowly area by area is the all new encrypted config data.
this started with a small certificate update in the modem ready for this. Not only that the mac broadcast on the older modem is affected. Older 200 down to 4100 are affected.
250 and 255 as you are aware do not broadcast themselves onto the network hence the lack of them in dhcp sniff etc. So virgin have decided to attack the cloners head on and use encrypted config data.
Simply put the config is sent to the modem in an encrypted packet and the modem unencrypts it and stores its information. Currently your forcing the modem up to 20 meg or similar by requesting that packet for your modem to be sent to you.
Well the server now sez sorry p off dont recognise that packet dont have that stored to me.
for instance you send in plain english.
250 cfg high please.
it expects the packet sent to be encrpted so it aplies its algo and codes the packet to this
zxexcreddfdjhwedfdfd
goes hmm dont have that erm bye logs modem off network 1k up 1k down. Its initial setup config.
but what you should of sent is i want dshgdsjfsjg9oruo config send it.
it decrypts packet ahh you want 120 mid config. and sends it back.
now heres where the fun is the data is encrypted on a modem by modem basis no 1 modem or 1 modem ack packet is ever the same. I.E. THEY aint scannable. A cloned modem dont work as it carnt force a config.
Some people say erm well piece of p atm dead easy let the modem accept the normal config dont force one. Okay lets look at this for a mo.
120 gimme a config. okay vm check do you have new certificate installed no okay ill let you have it this time.
120 gimme a config. hmm still no certif update k this time.
120 gimme config look you should of taken an update now ur a clone
1k up 1k down. Modem banned of network.
Think this wont happen, ladies and gentlemen its happing right now ntl areas are updating as we speak. Happened in my area last week and modem banning is there now.
enjoy the time you have until uk full rollout.
************************************************** *

All this makes sense to me because i have some 250 which i have reflashed with the normal 250hack_dump_telnet.bin and also with Infinit-dump-new.bin.
I have then changed user name and password put a new mac (scanned from another ubr in my town on october 7th)
changed the docsDevSerial to the same as the mac but without the colons.
Set the usual stuff annex tuner ds ect.
Disabled config file forceing and used the macs normal config. then rebooted.
i then get the usual boot. on 192.168.100.1 i can see that the config is encrypted as its gibberish, but none the less it proceeds to register on the network then renew the ip to wan ip eg 81.115.**.** (strangly tho no matter which mac i use i always get the same ip?!!?)
Once the ip has changed i get basic internet connection at say 4mb ds from a light mac.
Its enough to load google and sometimes enough for a couple of other site but then after 2 mins or so it goes to 1k up 1k down (ie says website found waiting for reply then wont load any pages up, if u leave it for a good minute the page will eventually load.

Im stumped ive tried everything.

Any Ideas?

This is my reason for wanting to revert to original firmware.
I've tried to download the original image off a 250 (successfully) an then put it back on another 250, it wrote the image no probs {even if it did take 16 hours} but then failed on the crc hcs.
Does anyone know why would this happen?
Does each modem have an id which is used in the crc algo?
I would have assumed that an exect binary copy of the firmware would have the same crc as the original if nothing was altered

cheers in advance mick.

looks like it could be the end of hacked modems
shame i was so slow getting one, only recently bought mine but thats the risk with this, no guarantee of it working indefinitely.
hopefully somebody that has a clue ie. not me will find a new way to bypass this a some point.

That post is very difficult to read with little punctuation.

I have heard that with the encrypted config files you cannot force a config, but even with infinite firmware you can get the default config file for the MAC in use and surf the net.
