ANSWERED Jasper 512 Green Blinks a few times then stops?

[Shadowlance]

Hey there, im hoping someone can help me out a little, i have a jasper 512 6751, ive tried almost everything i can find. I cannot get it to boot even to xell. what it does is flash green about 5 times then it will just stop flashing, I've checked and reckecked my connections, i've built multiple images using various methods. the latest one is with nandhealer 0.73 and the newest multibuilder. ive tried the cap on A and ground. Any suggestions? or am i SOL. Thanks in advance for any help

Can you post some good clean pics of your soldering of all the points please as this will help us to help you?..
Also have you checked your Ldv is right?

 

[Shadowlance]

that's the crappy thing, all i have is an iphone, i'm very confident in my connections, i've done about 15 successful rgh. besides having the cap on a and ground and between blue and D is there any other ways of cap manipulation or image creation i don't know about?

ldv is 0

Xell doesn't care about LDV.

Did your console still boot with the stock NAND in place? It's right there in the roadmap for noobies, so you should be doing this first.

yes if i put the stock nand back on it boots fine, if i could just get the dvd key i'd be happy as sh*t but i can't even get that

maybe i'll flash the original nand back again and start fresh again, just saw nandhealer .74 out so maybe i'll try that one out, though i don't think it takes all that much to make a xell img.

 

[Martin C]

Have you tried with a normal AV cable?

 

[Shadowlance]

I've tried both with each attempt, flashed back to stock again and all works fine, I'll start from scratch again tonight...

 

[Martin C]

Try and reflash xell again. Do you have any bad blocks in the first 50?

I got 3 dumps last time, all perfect and cross matched, I'm going to try the new nandhealer unless there's something else you might recommend, and just to clarify for me, the caps on A and ground or between D and blue are mainly for slow boots right, also is there anyway to spoof the NAND into like a 16mb one maybe, I came across a thread on it awhile ago but can't for the life of me find it to read more lol

Can you post pics of your soldering / wiring?

i would recommend using a different ecc glitch compiler. sometimes not one compiler works for all motherboard. i found this out the hard way. multibuilder can be a pain in the ass if you have a widows base anti virus as when your anti virus is cleaning up actually takes some stuff from multibuilder and marks it as a computer threat. same goes for jtag tools. when creating ecc try eith rogeros easy gg build or coolshrimps jtag tools. not all compilers are equal. also check your wiring when writing to the nand. make sure you are getting good ground because coolrunners work by grounding the hana that is what the glitch is

I had a issue like this and got round it by re-soldering the points .... Work for me

Havent had a chance to get back to it yet but thanks for the tips, when i get a chance to try them i will report back. Really appreciate the advice.
