Matrix Infinity clone modchip. Can it be flashed?

[Nightman]

Can it be flashed with the newest Infinity firmware? I saw it at www.r o b o t p i g.com I emailed them, but did not get a clear answer, as they did not know.

I don't need the age old lecture how clones are bad, buy the original, etc. This chip is not for me. I have a customer who is wanting to buy it instead of shelling out the extra couple bucks for an official Infinity.

It cant be flashed because they have added clone protection so it wont work. Sorry to hear about it. Plus some dont work when you change the settings. They are junk anyways. I hope this helps.

My experience say :
NH 9 and MODBO 1.1 CANOT flashed and DONT save any changes you have make in
Infinity option configuration menu :
------------------------------------

Press TRIANGLE + CIRCLE to enter the configuration menu.
---------------------------------------------
Just clone stop to work

[messiahfan2003]

I'd still get the real infinity.

Yep, you guys just gave me the info I needed to talk him into the original Infinity chip. What good is a flashable Infinity clone if it cannot be flashed, lol!

[summ0ne]

you can prolly prevent the clone from dying by write protecting the eeprom on it

villasg - tell me which pins on the little 8-pin chip are connected to 3v3!

EDIT:

i see on the pic its pin3!
just lift pin3 on the little on the modbo/nh9/InfinitySE and take it to gnd when u install it - and it should never die :-)

here is a practical way of doing it (diagram)

Then u have a cheap and safe non-upgradable infinity which works great with its current firmware.

from SAIFUN is conected in =Vcc the legs 3 . 7 . 8
What doing the pin 3 ??

[summ0ne]

not sure its pin3, might be pin7

just let me find the datasheet and make sure.

it is the WP (WriteProtect) pin - if u take it to gnd it protects the chip from being written to

yup, its pin3 B)

[villasg]

You are correct

I try it tommorow .
Thanks

[villasg]

I thing this have not effect .
Mybe is good to lift the pin 5 ( serial input )

[summ0ne]

nooo - it needs to have serial input to boot!

trust me.

if the chip stays dead even after power off - this means that something wrong got saved somewhere. and the only place on the chip info can be saved is on that eeprom. if u writePROTECT it, its PROTECTed. nothing can change it and the data in it stays forever the same!

get it ;-)

[villasg]

I go to workshop to make some tests now.

[summ0ne]

LOL - report ASAFP!

[villasg]

Downgrade to 1.36 OK ---> load copys
Upgrade to 1.39 OK ----> load copys
I go to Infinity option configuration menu :
------------------------------------

Press TRIANGLE + CIRCLE to enter the configuration menu.
---------------------------------------------
change the delay setings from 10 --->2

AND STOP WORK the modchip (black screen)
Dont go to re upgrade (TRIANGLE + CIRCLE ) --->black screen
Dont me disabled ( start pressed ) --------> black screen
Can go to Infinity option configuration menu (Press TRIANGLE + CIRCLE)
Can make changes (like delay setings) no black screen)
Again dont load anithing --->black screen
Again can go to Infinity option configuration menu (Press TRIANGLE + CIRCLE)
Can make changes (like delay setings)(have keeping the previus changes) no black screen


godd bye modbo

[summ0ne]

what do u mean downgrade/upgrade....

how can it do that with eeprom protected :\

you surely did it wrong

[uns97]

Summ0ne: If you set the write protect pin to low, still there is the writeable block according to their Table 10 on page 21. This is the only reason why vilasg was able to downgrade/upgrade it and save the settings. Correct me if I got it wrong.

regards, Stephen

[summ0ne]

you are right, the WPb pin has to be enabled by programming a register in the eeprom.

so getting this fix to work is not for every doityourselfer.

but sure would work when designing modbo 1.2

sorry villasg

[aqua]

the modbo can be flashed using infinity software, they come with v1.38, you can upgrade to 1.39, downgrade to 1.36 and visa versa with no problems. The only major problem is you can't touch the configuration settings without blowing the chip.
This is a shame but dont forget many other chips dont have a config option, so just imagine this dont either!!! If we could disable the chip from blowing when changing stuff in config settings, then this will make this chip safer to use!!
