I have 32Gb SDHC card. I found the pin layout from the site and soldered on circuit board.

Now the Flash tools detect the chip Id Perfectly.

while creating the dump of chip it gives error.

Hello!

It's a controller influence. You can read ID but controller in SD card block access to NAND core. Possible solutions:

1. Physical destruction of integrated controller (for example - make X-RAY picture, found where controller is and drill it);
2. Influence with power supply. Try to send not VCC but V2 power supply with default 3.3V;
3. Try to reduce power voltage from 3.3V to 2.6 - 2.8V;
4. If your SDHC has additional VCC contact on pinout, you should send power supply also on this VCC.

Hello,
I would suggest you play around with power and reduce it ,An Xray would be cool i have no idea which kinda Xray is necessary
