Description of problem:

Hello, friends. As the title says, I decided to try to RGH my Jasper console and I'm stuck on the first step, I just cannot get two matching nands.

I watched video tutorials about 10 times, installed the JR Programmer drivers without problems, soldered everything, got Jrunner to read the nand, during reading I get two errors - Error: 250 reading block 7A0 and Error: 210 reading block EFF, errors are the same on both reads but every time it finishes the reading I get "Oh no" sound and message that nands are not the same, when I click ok to show differences this is the message I get:

Comparing...Takes a while on big nands
0x0EFF

I resoldered and trimmed the wires a couple of times,  used multimeter to test for continuity between points on the board and on the JR Programmer, tried to read the nand about 5-6 times and I don't know what to do anymore, what am I missing or doing wrong? Any help is appreciated. Thanks.

Your soldering is good, i would try to take your dumps and just use another tool to check if they match. Jrunner might not like the big files for some odd reason

Thanks man, I will try that. The funny thing is, I just tried to RGH another Jasper console (with 16mb nand) and everything went without a hitch on the first try.

At least I know that the programmer is working fine.

jrunner shouldnt have a problem with it.. 

i'd suggest using a different version of jrunner.. yours is putting the nand into a jrunner 0.2 folder.. you can always PM me the nands.. and i can check on my end??

 

edit:

ok, so i would also try re-dumping the nands.. since your nand difference is only in 1 spot.. is what that code is at the bottom..

 

edit 2: and also they used to recommend dumping your nand 4 or more times.. and definitely do NOT touch the programmer.. as the wires could be loose at the connector.. and cause an error
