quote from other thread:

have a corona 4g, kids seem to updated it don't know really how. RGH wont boot. I have orig nand and cpu key. When I reflashed orig retail nand i get a red dot so I guess ldv changed. How can I rebuild an RGH image with the new ldv? orig nand says in jrunner LDV upper right 0, lower left 3, lower right 0. In the updated image, it says upper right 0, lower left 3, lower right 2. which one is my current ldv?

where did this updated image come from ??

you have 2 options:

1. install CR4, flash xell and check your LDV value and then create a freeboot image accordingly

2. install CR4, create latest freeboot image starting with ldv 3 and keep going up by 1 untill it boots

I would go with #1 as it is easier

first one is a dump after update, second one dump after update.
I tried flashing xell and all the switches in CR4 but I only get green blinking light and no xell

Tried also creating freeboot image and all switches and post bit combo with ldv 3-5 but just green light blinking again...

In xell it doesn't matter what image i use right? whether I use the dump before or after the accidental update is fine right?

how long are you testing each dipswitch/postbit setting ?

 

[WalangAlam]

2-5 mins each dip i think. I just on it then play COC then change dip again.

your soldering looks good

wire length doesn't matter with CR4 but I would try and keep it as short as possible..

all I can say is position the CR4 closer to the fan that way you have shorter cpu_rst and postout wire ..

shorten the E wire as much as you can and go through all the dip/postbit settings again.. there's not much to it.. don't know why you're not able to boot xell

I noticed "Use Edited Options Selected" in the log in your original post.. what did you edit?

I don't suspect the soldering too. Must be the way I'm building my xell and freeboot image or my nand source.
just the temp set all to 60s.
