flashkit -- a new way to flash your phone

[maxx_730]

because the /ezxlocal directory is a different partition of the DiskOnChip thingy or whatever its called. do a df -h to see what partition ezxlocal is

I am trying to modify the gaintable on my E680 (original firmware). Reading some threads here, I figure that I have to first copy my root filesystem, mount it on my PC, edit it and reflash the filesystem using flashkit.

I can't figure out how to copy the rootfs.
When I telnet to the machine:
# mount
rootfs on / type rootfs (rw)
/dev/root on / type cramfs (rw)
none on /ram type ramfs (rw)
proc on /ram/proc type proc (rw)
/dev/tffsa on /usr/language type cramfs (rw)
/dev/roflash2 on /usr/setup type cramfs (rw)
none on /dev/pts type devpts (rw)
/dev/mtdblock2 on /ezxlocal type vfm (rw,noatime)
/dev/tffsb1 on /diska type vfat (rw,noatime)
/dev/mmca1 on /mmc/mmca1 type vfat (rw,noatime)

# cat /proc/mtd
dev: size erasesize name
mtd0: 00020000 00008000 "Bootloader"
mtd1: 000e0000 00020000 "Kernel"
mtd2: 00580000 00020000 "VFM_Filesystem"
mtd3: 00020000 00020000 "Logo"

Turns out, /dev/root isn't actually there. Also, the flashkit guide refers to mtd5 and upwards which aren't listed. So I tried using flashkit.

After loading rwflash.o, I telnet back into the phone and this is what I get:
# cat /proc/mtd
dev: size erasesize name
mtd0: 00020000 00008000 "Bootloader"
mtd1: 000e0000 00020000 "Kernel"
mtd2: 00580000 00020000 "VFM_Filesystem"
mtd3: 00020000 00020000 "Logo"
mtd4: 000e0000 00020000 "R/W Kernel"
mtd5: 018e0000 00020000 "R/W RootFS"
mtd6: 00020000 00020000 "R/W Setup"
mtd7: 00020000 00020000 "R/W Logo"

But again, when I try to create a cramfs file of my rootfs:
# dd if=/dev/mtd5 of=/mmc/mmca1/my_rootfs.cramfs
dd: opening `/dev/mtd5': No such file or directory

So how do I get hold of the filesystem with /usr in it? Can someone help me out with this?

use flashkit to unlock the mtd partition, or whatever its called. after that then you can dd it out: dd if=/dev/mtd5 of=/mmc/mmca1/my_rootfs.cramfs

[antrixangler]

yantz, that's exactly what I did. Unlocked the mtd devices and tried dding it but /dev/mtd5 doesn't exist.

[yantz]

you have to carry on with start.sh, it will unmount the rootfs and mount miniroot

[cyph]

Problem is.. /dev/mtd5 node is created on the phone. So you have to create it yourself.

mknod /tmp/mtd5 c 90 10
dd if=/tmp/mtd5 of=/mmc/mmca1/rootfs.cramfs

Note that mtd char minor numbers are incremented in multiples of 2. Even numbers are read/write devices while odd numbers are readonly.

e.g. mtdX is created using mknod mtdX 90 X*2

[antrixangler]

thanks yantz & cyph. I can read from /dev/mtd5. But a new question now

The guide says I should be using 'bs=4096' when writing the cramfs image to the phone. Should I use the bs=4096 when copying my root from the phone? I get different record numbers..

root # dd if=/dev/mtd5 of=/mmc/mmca1/myroot.cramfs
50944+0 records in
50944+0 records out
root # dd bs=4096 if=/dev/mtd5 of=/mmc/mmca1/myroot_bs_4096.cramfs
6368+0 records in
6368+0 records out

Which one should I use? I would like some confirmation before I try to flash this image back on the phone

[yantz]

hehe i just used flashcp -v

Hi all,

I tried to use the first part of the flashkit procedure(steps 1-4), in order to add another language to my phone. I saw the flashrw_status file (`unlocked`). When I tried to change something in the folder usr/language/string, I got ` operation not permied` message. I also couldnt delete the flashrw_ststuas file. What did I do wrong? Do I have access to change files through the telnet using this procedure?

Thanks

This doesnt actually make the RO fs's RW'able, it unlocks them for reflashing.
