Hello guys,
i want to write a update-script that makes some changes on the phone,
but before i can extract files, set symlinks, etc. i have to mount some partitions.
The format of the partitions is MTD, but i don´t know how to find out which block is for /system, /hidden, /data, etc. and where is the block?
I searched much in the internet, have read the instructions for edify-scripting and so on,
but i´ve never found it for MTD and never found how to find out which block is which partition.
I hope you can help
Every phone is different, so for you to get useful advice you need to state what you are using.
I've always found it very helpful to look at the updater script for custom ROMs since they have mount instructions for /system.

I realy have to thank you for your reply
I´m using a Motorola Motoluxe XT615 and the problem is, theres no custom ROM out there.
A friend has developt a awesome JB-Design for it and we know how to mount system, but anything else doesn´t work.
The command we´ve used:
Code:
run_program("/sbin/busybox", "mount", "/system");
Thats the output when i´m in /dev/block and enter command "ls":
Code:
dm-2
dm-1
dm-0
vold
mtdblock11
mtdblock10
mtdblock9
mtdblock8
mtdblock7
mtdblock6
mtdblock5
mtdblock4
mtdblock3
mtdblock2
mtdblock1
mtdblock0
loop7
loop6
loop5
loop4
loop3

loop0
mmcblk0p1

mmcblk0
Maybe this is usefull, too. Output of command "cat /proc/mtd":
Code:

Well, that will work if a ROM with busybox is already installed.
Here's what's in the updater script for the HTC Desire S ROMs:
assert(getprop("ro.product.device") == "saga" || getprop("ro.build.product") == "saga");
mount("ext4", "EMMC", "/dev/block/mmcblk0p25", "/system");
...
format("ext4", "EMMC", "/dev/block/mmcblk0p25", "0", "/system");
mount("ext4", "EMMC", "/dev/block/mmcblk0p25", "/system");
package_extract_dir("system", "/system");
Nope this helps. I think you need to use MTD instead of EMMC. And, obviously mtdblock9 instead of mmcblk0p25.

Finally i got it, thank you
It wasn´t even that hard. The right command is:
Code:
mount("MTD", "userdata", "/data");
mount("MTD", "system", "/system");
mount("MTD", "hidden", "/hidden");
Thanks for your help
So, i was looking for cyanogenmod 12.1 for mt6582 and i saw this CM 12.1 for sprout 8

I'm having blkdiscard error. Im using TWRP. Any help?
Bump, anyone?
My old trusty P8000 stopped reading it's sim card and I have to get a new phone, so I thought this would be the perfect time to do a little hacking on it.
I'm a total noob to android, I've managed to root the phone and install CWM.
I've also cooked up a custom rom in android kitchen, but I'm having some problems passing the proper mount command to the update-binary.
My updater script reads:
Code:
format("yaffs2", "MTD", "system");
mount("yaffs2", "MTD", "/dev/block/mtdblock5", "/system");
show_progress(0.500000, 0);
package_extract_dir("system", "/system");
When I run the update.zip in CWM it comes back with installation complete, but the log says unmount of system failed: no such volume.
Does anyone know the proper mount commands for these old MTD flash drives?
Yes I'm sure the "system" partition is /dev/block/mtdblock5
Code:
~ # cat /proc/mtd
dev: size erasesize name
mtd0: 008c0000 00040000 "boot"
mtd1: 008c0000 00040000 "recovery"
mtd2: 00f00000 00040000 "fota"
mtd3: 09880000 00040000 "cache"
mtd4: 002c0000 00040000 "persist"
mtd5: 0e940000 00040000 "system"
mtd6: 00280000 00040000 "splash"
mtd7: 20a00000 00040000 "userdata"
The format command only works if I use:
Code:
format("yaffs2", "MTD", "system");
It doesn't work as:
Code:
format("yaffs2", "MTD", "/system");
Something to do with the MTD partition table being hardcoded into the kernel.
Also, is there any way to view CWM installer logs other than from the advanced menu on the phone. I'm only able to see the last few lines of the log, and it doesn't give me any clue why "/system" doesn't mount.
Thanks for any advice you can offer.
Ok, I fond the answer in this thread http://forum.xda-developers.com/showpost.php?p=17594598&postcount=30
Code:
mount("yaffs2", "MTD", "system", "/system");

The only thing what i wanna do is that the /system gets mounted, then, the system should install, and then, /system should be unmounted.
Can someone help me? I have a Redmi Note 4X and TWRP 3.1.0.0. Thanks.
