[Sahil_info]

my friend update his rgh xbox 360 corona v2 thru online ofw update.now xbox not boot.power on green light & fan speed & noice like jumbo jet.
i dont have original nand dump or cpu key or xebuild image dump

anybody help ..if understand my problem

 

[Martin C]

He'll need to build an image using the existing dump and CPU key. Hardware will be needed to write to the 4GB NAND.

 

[Sahil_info]

sorry sir ..i dont have existing dump or cpu key

so it mean .... XBOX 360 DEAD

 

[Martin C]

Not at all - the dump that's on the console will be enough to build a new one.

 

[Sahil_info]

ok .. i remove all wires & chip ..but it wont boot ...so how ??

 

[Martin C]

You need to dump the existing NAND, write xell and get the CPU key. then built a new RGH2 image and write it back.

 

[Sahil_info]

ok martin G ..i try then i reply

 

[Sahil_info]

got cpu key but when i put this key in jrunner using dumped nand jrunner says wrong cpu key

 

[Sahil_info]

see this also martin i got cpu key ..check & input carefully but says wrong cpu key

 

[Martin C]

it just means the original image is corrupt. You just need donor files from a Corona 4gb (decrypted). You can then build a new image.

 

[Sahil_info]

from where & how i got this ? donor nand ...i have many of consoles clean nanddump

 

[Martin C]

Extract the files of any clean 4gb dump (as long as you have the CPU key). Then use the J-Runner PDF to help you build an image without nanddump.bin.

here, read this until martin gets back to you. he's smarter than me...:crazy:

[Martin C]

Because you didn't follow the instructions. You need DECRYPTED files, so your NAND dump you're using as a donor needs to have the CPU key with it in order to get them.

plzz help

 

[ezzda1]

You have built a retail image with donor files. This is why you get flashing red and green lights.
For a retail image the kV has to be the original one from the console you are using it on.

 

[Martin C]

Why are you building a retail image?

I thought you wanted an RGH?

Did you not read the sticky which was linked for you?

"These steps can only be carried out to completion if you created an ECC from your original NAND. If you used a DGX ECC (or a >14719 ECC PRIOR to J-Runner 0.3 (build 1)) then you won't be able to restore a stock NAND. However you can use the steps to build an RGH NAND."

I have a suspicion that the image you wrote to the console isn't corrupted at all. You wrote someone else's image to it, which is why there's a mismatch on the keyvault.

I strongly suggest you stop ALL modding until you fully understand what you're doing.
