Hi,
I'm new at te forum but i have made over 500 installs of rgh and jtag ect. I would like to share with you my experiences with corona v6 motherboards. I have already made few installs on v6 and everything went smooth until yesterday. I had 3 consoles that after reading the memory and injecting ecc in it stopped responding at all. No power and thats it. After many hours of debugging my work i figured it out.
First one had burned resistor on CS line which is wierd because for MMC is active low.
The second one had bad block at first 64mb of SKHynix e-Nand memory. After replacing and programming it got back to life.
And third one had f***ed up Southbridge. I desoldered one from my Corona and placed in dead one, and guess what? It got back.
My conclusion here is that either e-Nands are more fragile to current on MMC reader or i was very unlucky. I used the same reader for over a year and something like that never happened to me before. Of course after the first fail i got new reader, but as you can see it havent changed a lot. Well everything went well because i was able to fix the consoles but i got very nervous about it. For those who got same problem i suggest to chceck the resistors on e-Nand and chceck the memory itself.
If you think it is worthless just erase this post but i think it might be helpful for those who got stuck in such situation.
Sorry for my bad english. I'm not used to write post in foreign language.
Regards.
