More info:
After about 3+ hours, Ldr.bin update.txt dumped the internal stuff to SD and here is what it looks like inside garmin. [Only registered and activated users can see links. ]
Attached file listing dir /s. I noticed it 10gb dump. Few folders are copy's like /voices/n/, /system/ are the same as root. I believe it was caused by update.txt. I also found out that reg 5.bin is sw 6.40 but 14.bin is sw 4.60. Both hwid 827. So we have boot/fw mismatch.
