Solution For Interface AP-OS: Error Flashing Subscriber Unit Error 0xE0020086


Recently (actually a while ago) , one of my friend passed a broken A780 to have a look, It only has the basic function of receiving the phone call, partial sms function ( only number keypad) . The scary part is every one is turned into exclamation mark and the memory is full error.

I have dug through Google but it seems lots of people having the same problem but the only solution is to bring the phone back to the service station.
Since the EZX phone is NOT market in New Zealand and the phone itself has no warranty. I had a quick look of the file structure with df

Filesystem           1k-blocks      Used Available Use% Mounted on
rootfs                   54468     54468         0 100% /
/dev/root                54468     54468         0 100% /
/dev/roflash2              348       348         0 100% /usr/setup
/dev/mtdblock2            5312      1564      3748  30% /ezxlocal
/dev/mmca1              991488    535728    455760  55% /mmc/mmca1

What happened to /diska and /usr/language?  DiskOnChip is damaged?

Here is solution.

1. The phone has to be modified first to be able to run startup script.
2. Mount diska and usr/language from memory card.

However, the memory card is not mounted at the booting time. Hence we have to manually mount the memory card before mounting.

So here is the script. You will need to extract cg33 into the language directory first.

insmod /lib/modules/mmc_base.o
insmod /lib/modules/ezx_mmc.o
mount -t vfat /dev/mmca1 /mmc/mmca1 -o uid=2000 -o gid=233 -o iocharset=utf8 -o shortname=mixed -o umask=002 -o noatimemount –bind /mmc/mmca1/.system/diska /diska
mount –bind /mmc/mmca1/.system/language /usr/language

Now the A780  is working again ;)
