Akai mpc 2500 want read jj os 3.10

I pick up a brand new akai mpc 2500 w/cd rom drive with verison 1.00 from the pawnshop for $350, i played with the machine all weekend, then i upgraded the mpc to v1.24 from the akai website, then later today i upgraded to the free version of jj os. now my mpc is stalling when i turn it back on!!!!! the screen say, "akai mpc 2500 16mb installed" that's it!!!!!! I think I erase the os 1.24 from akaipro.com because now my machine don't work at all!!!! it don't get off that screen, i need help asap!!!!!!! any advice, do i need to buy a new hard drive and install the os from akaipro so it can work again!!!! or throw the damn back to the pawnshop!!!!! it work before with no problems at all, then i **** it up!!!! HEEEEEEEEEELP!!!!!!!!!!!!!!!!!!!

have you tried installing the OS from the CF card again?

the screen is stuck and the cd rom is flickering like it's trying to find something. i tried to hold down erase when i power the unit on, but no luck! i wish i can just go back to v1.24, i hope i didn't erase the hard drive, if so, how can i reset the whole unit!!!! i can't reinstall the os since the screen is stuck!!!! I might just take it to one of these guitar centers outsource, to have them reset the unit this weekend!!!!!!! shiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiit I'm better now!!!! but i need help!!!!!!!!! i have this unit link to my emu e4xt sampler and i have a session this weekend!!!!

did you try holding down WINDOW before you turn the power on?

the instructions are at:
http://www.akaipro.com/stuff/contentmgr ... update.txt
start from ">>>How to update MPC2500"

Im at the mpc2500 os update screen and it say, "insert memory card" i did that but the unit isn't reading the card damn!!!!! i was only using the cd rom to load sounds never the memory card from this past weekend. I just copy the mpc2500.bin to cd rom and load the cd into the unit by doing what you told me (w/o memory card) but the unit isn't responding!!!!! OMG 4 days before my studio session


P.S.

whoever is the first person to help me fix this issue, will get a huge sample collection from bangin-beats.com (nearly 50mb) So far Pastor of Muppets is the only one trying to help! Thanks

turn the MPC power off
put the CF card in a computer's card reader
put mpc2500.bin on the CF card
put the CF card in the MPC
hold WINDOW on the MPC
turn MPC power on
...
profit!

Nah, try what Pastor said and see what happens.

The screen is still stuck, can i just open the unit up and disconnect a few cables and put it back together then it will start up hopefully!!!! I think i erase the os on the akai daaaaaaaaaaaaaaaaaaaaaaaaaamn!!!!! Im screwed like travis the ape I hit window when i power the unit on but i can't get the unit to read the mpc2500.bin on cd rom or memory card i want to take it back, but my head is spinning and thinking that its not bad as it seem heeeeeeelp anybody

umm, yeah ... that might work

you could also try hitting it with a hammer, setting fire to it and then pissing on it

well that might be my final hope back to reason 5 until i can figure this thing out Thanks for the advice guys

adjust the contrast...


JJ OS adjusts the contrast of LCD by a [STOP]+ DATA wheel

How can I enable my compact flash card reader in my unit? I can't get it to read. Is it possible to go inside of unit and see if the cable connected? I think I can fix this unit today but need a little advice, it don't reads the CF drive, only the CD-RW drive only...Yes the screen still stall though! but i can hear the unit trying to load the something but not sure. I install 128mb this morning! now it reads MPC2500 (128MB installed) also i bought a original 2GB AKAI CF CARD.
