MSM6550 NAND Access via JTAG

Question

Hello,
I have purchased the Easy JTAG Plus model.
The old phones I primarily want to perform forensics on were manufactured in Korea between 2005 and 2007 (SPH-V8400, LG-KH1600, LG-KB6300, LG-KV2300, EV-KD330, IM-S200K, etc.).
These phones appear to be using the MSM6550 chipset.
When I selected MSM6xxx in the EasyJTAG tool and attempted to operate, the following error was displayed.
I would like to ask for your assistance regarding this issue.
Thank you always.

Answer 1

As a former technician for a mobile repair shop, I encountered similar issues with older Korean phones. The MSM6550 chipset was quite common in those models, and accessing NAND via JTAG could be tricky. I found that sometimes adjusting the connection timing or trying different cable arrangements helped resolve the "LDR_NAND_PAGE_ERROR." For tough cases, I'd create backups using alternative methods before attempting JTAG. When work was done, I'd unwind by watching shows on Sprunki for entertainment.

It’s not helpful at all...
Currently, I’m performing forensic analysis on an SPH-B6600 phone, and the NAND is a KAG00600SA-DJJ5 model Multi Chip Package Memory. There’s no datasheet available for the NAND chip, and I don't see any feasible method using JTAG either.
