Corona V3 Problems

[Tag234]

EDIT: excuse the title, it is a v4 NOT a v3

Hello,

Forgive me if this is in the wrong spot. I did not really see a better place to put it, and I am trying to flash the DGX ecc to the console... I am having issues Reading/Writing from the Corona v4. I have the 4GB QSB all soldered in, and I have an SD card reader that I know has worked for V2s in the past.

This console has the Samsung BGA Chip, but still has post out points. In J-Runner, I get these problems:

IE the NAND shows up at 3680MB, so it says it is odd size. When I try to read it anyways (hit OK) J-Runner throws an exception.

I followed a different picture and did bridge the resistors R2C7 and R2C6, but those are just for E and F. The R2C10 resistor already has a resistor in place, so I figured I did not need to touch it. What am I missing here? I tried to search around, but can't find any info on what I am doing wrong... It is my first v4, apologies.

The Samsung BGA is a v4 and shouldn't have a post out?! You're sure it ain't a v2?

Please post some pictures of your mobo and soldering.

Correct if i'm wrong but isn't that QSB meant to v2 and v4 coronas (without hdd)? not v1 and v3. V3 has 16mb NAND. that's why you have NAND mismatch.

I do not know if you are correct or not, but I do know that after reading the NAND with a NAND-X (which I did first because I was not sure), I got a flash config 0xC0462002 which indicates Corona 4GB. It also said Header is Wrong

I am sure it is a 4GB, either v3 or v4. I did not take a picture of Post Out on the bottom, but the points exist on the bottom of the board.

My camera isnt too great so thats the best pic i got, but I did multimeter all of the connections next to each other and none were shorted


EDIT: Correction: It is a v4. I just learned that although the points look like they exist on bottom, they arent really there. My apologies. I still have the same issue tho, its just a v4

Does the console still boot?

its a v4. did you remove the clamp to see if there are traces concering post out.
if you don't have traces running there you need a post-fix adapter

With the switch on R/W, it does not, just beeps. When it is on X360 it boots fine

You are correct, it is a v4 and ive got a postfix adapter so ill install that later, but for now i just want the nand readable
