hi @all,
is there a way to convert a mtd partition to another filesystem?
i've tryed the following procedure:
1.) boot to recovery
2.) login to system via adb (adb shell)
3.) mke2fs -m 5 -b 4096 /dev/block/mtdblock1
at point 3, it gives errors and nothing is happen.
now, i've tryed to flash a ext3 filesystem on this partition via
flash_image system system.ex3.img (found a explanation on how to create a ex3 system.img), but after mounting the /dev/block/mtdblock1 on /system it shows still device as "yaffs2".
would be nice, if someone can explain me if it's definitvly not possible to convert
mtd partitions or tell me a short tip what can i test
ThX
Andy
An anything known about this in the last year BUMP
Never tryed this rom but seems very good :good:
I like switch between roms using this to restore sms and call logs from nandroid backup:
https://play.google.com/store/apps/details?id=com.h3r3t1c.bkrestore&hl=it
..so no good for me use odin to switch to this rom when I need
What happen if:
flash FLYonGB
recovery --> backup
Flash CM 10.1 v7
Recovery --> wipe data, cache, dalwik ..all
--> advanced restore --> restore boot and system from FLYonGB nandroid backup? :silly:

Dont Brick Ur Device
I don't belive I brick my phone this way..
..anyway I will not try
GB roms and JB roms have diferent partitioning, so if anybody will to switch between those roms ALWAYS need a repartition in Odin.
Data,sistem, cache..... Are not in the same partition, this is the main reason of the problem.
Please dont forget this rule or you will Brick your phone.

i never followed traditional flashing trend like full xxkpe > so n so ... i just flashed DXKF1 (Korean version )froyo stock rom with a pit > XXKPQ-PDA(Siberian ver.) > DDLF2-PDA> cm9 >cm10 --- i personally followed this trend and never faced any soft brick hard brick or any thing.The stock roms i used were on multi CSC so that also did not effect. :angel:

One question : Can we merge partition files i mean the code so both CM n GB can read from that single partition file. Don't know it is technically feasible or not .
My idea use FLTOnGB recovery to nandroid backup kernel+ramdisk and system image.
After installed cm 10.1 (so repartitioned the phone) use his recovery to replace boot.img and system with those of FLTOnGB nandroid backup.
Don't know if recovery stuff may work.. anyway I think things to change in ramdisk:
cfroot ramdisk: fota.rc
Code:
.....
# create mountpoints and mount tmpfs on sqlite_stmt_journals
mkdir /sdcard 0000 system system
chown system system /sdcard

----------------------- Journaling Disabler For Pico ----------------------
This is just a simple Zip to Disable Journaling on pico! as we use 2 or 3 extra ext4 partitions for OC!
It even clear's /sd-data,/sd-cache - for aosp
and /sd-ext,/sd-data,/sd-cache - for sense 4
Which means you need not always format your sd-card to switch between roms! .. But if you are switching from aosp rom to sense 4 you need to partition the sd-card appropriately!
Steps to USE:
******* Use this Zip Only when installing a Rom from scratch!... cause it wipes everything! ******
-- clear almost everything you can from recovery e.g factory-reset,/system,/boot,/cache etc
-- install this Zip! as like you do with any other zip (Prefered Recovery TWRP 2.4.X)
-- Flash Your Favourite Rom Now!!
I can use this even if i am not oc'ing?? Just like superwipe?
Disabling journal wont harm anything! Right?

From the wikipedia's article:
A journaling file system is a file system that keeps track of the changes that will be made in a journal (usually a circular log in a dedicated area of the file system) before committing them to the main file system. In the event of a system crash or power failure, such file systems are quicker to bring back online and less likely to become corrupted.[1]

For overclocking, the SD Card is used for the /data and /cache partition. In that case, the SD Card would be read more frequently as the /data and /cache partitions are the most frequently accessed and modified partitions while running the Android system. In that case, using a Journal would slow down the memory access times if the SD Card is not fast enough. Also, as many modifications are made to the /data and /cache partition, the SD Card would be going through the read/write cycle twice the number of times, once for the journaling and once for the "commiting them to the main file system". So, it is likely that the SD Card might get corrupted faster than it normally should. That is the reason why Class 4 and below SD Cards are likely to "go dead" soon when overclocking with cute_prince's new PLL2 overclocking method. And, this is why ateeq72 has made this flashable zip to disable journaling. It would reduce the possibility/risk of losing your SD Card and at the same time allow you to OC your phone.
Using this when you are not OC'ing your phone? I wouldn't recommend that you flash this zip, but you would need a slightly modified zip. Also, journaling, I presume you want to disable in your phone's sd-ext memory. It would increase your phone's performance in case you are using any memory increasing scripts like int2ext which mount the sd-ext partition in the /data folder.

Edit the file named "ateeqscript" using Notepad++.
Make sure the file looks like the one below.
Code:
#!/bin/sh
echo ***************Begin Disable Journaling Partition***************
/sbin/busybox mount -t auto /dev/block/mmcblk0p2 /sd-ext
rm -rf /sd-ext/*
/sbin/busybox umount -l /sd-ext
/tmp/tune2fs -O ^has_journal -c 1 -i 1d -m 0 /dev/block/mmcblk0p2
fsck.ext4 -Dfy /dev/block/mmcblk0p2
sync
echo ***************Data Partion Done***************
echo ***************Finished No Journaling Partions***************
What I have done? Simple. Removed all code related to /sd-data and sd-cache, and kept only commands necessary for the sd-ext partition.
---------------------------------------------------
@OP, I suggest a few changes in your script. First, the mounting commands are run, so, if the sd-ext is already mounted by the recovery (just in case, accidentally it happened), then, you wouldn't (or rather shouldn't) be able to mount it in another folder, namely /sd-data. I would suggest the following change in your flashable zip. Try to make it look something like the one below.
Code:
#!/bin/sh
echo "\"Disabling Journaling\" Script"
echo "Initializing script..."
/sbin/busybox umount -l /sd-ext
/sbin/busybox mkdir /sd-data

echo "Partitions Journaling Disabled..."
echo "Finished no journaling partitions"
Do we need to flash this zip for every new rom or just once is enough?

Can you edit this script with just the wiping part? As it is not necessary to disable journal for aosp roms!

journal disabling is required for only ext4 partition for max performace
if u dont use ext4 use any wiping script
the script keval gave format partitions to ext2 only not ext4

How to convert NAND ROM to SD-EXT ROM for MultiBootloader
Code:
After following this guide, your ROM can be use with [URL="http://forum.xda-developers.com/nokia-x2/development/sbl-multibootloader-v1-00-04-10-2015-t3217360"]MultiBootloader[/URL]
THIS GUIDE IS NOT FOR NOOBs
Requirements
Knowledge about Android Image Kitchen
Notepad ++
A nand ROM extracted
Instructions
Delete the RED COLOR
Add the BLUE COLOR
Step 1: Modifying boot.img (FOR STOCK KERNEL ONLY) - Check post #2 to download the modified boot image, you don't need to edit it yourself.
Use Android Image Kitchen's unpackimg command to unpack the boot.img file from the ROM your want to port.
Go to Android Image Kitchen\ramdisk folder, edit these files:
fstab.qcom
Change like this:
Code:
# Android fstab file.
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK
#TODO: Add 'check' as fs_mgr_flags with data partition.
# Currently we dont have e2fsck compiled. So fs check would failed.

mount ext4 /dev/block/mmcblk1p4 /custom nosuid nodev barrier=1 ro[/COLOR]
Repack boot.img and copy to the ROM folder.
Step 2: Modifying updater-script
Open ROM-name\META-INF\com\google\android\updater-script
Find:
Code:
mount("ext4", "EMMC", "/dev/block/mmcblk0p19", "/system");
or
Code:
mount("ext4", "EMMC", "/dev/block/platform/msm_sdcc.1/by-name/system", "/system");
Add these lines above it:
Code:
[COLOR="blue"]ui_print(" Mounting Partitions ");
mount("ext4", "MMC", "/dev/block/mmcblk1p2", "/system-ext");
mount("ext4", "MMC", "/dev/block/mmcblk1p4", "/custom-ext");
mount("ext4", "EMMC", "/dev/block/mmcblk0p20", "/cache");
mount("ext4", "MMC", "/dev/block/mmcblk1p3", "/data-ext");
ui_print(" Formatting Partitions ");
delete_recursive("/system-ext");
delete_recursive("/custom-ext");
delete_recursive("/cache");
delete_recursive("/data/dalvik-cache");
delete_recursive("/data-ext");[/COLOR]
Find this line:
Code:
package_extract_file("boot.img", "/tmp/boot.img");
Change like this:
Code:
[INDENT][COLOR="Red"]package_extract_file("boot.img", "/tmp/boot.img");
run_program("/system/xbin/busybox", "dd", "if=/tmp/boot.img", "of=/dev/block/mmcblk0p10");
delete("/tmp/boot.img");[/COLOR][COLOR="Blue"]
package_extract_file("boot.img", "/emmc/kernels/[I]your_rom_name[/I].img");[/COLOR][/INDENT]
Find and change all /system/ to /system-EXT/
Find and change all /custom/ to /custom-EXT/
Save.
Step 3: Create the ZIP
Make sure you have copy the modified boot.img to the ROM folder
Select all the files and folders in the ROM folder (custom, system, META-INF, boot.img,etc..)
Compress into ZIP file.
Done.
<EDITTING>
I have modifed the boot.img to boot into sdext ROM:
For stock based ROM: stock_ext.img - thanks to @symbuzzer for adding some features and fixing the ril & sdcard bugs
modified_stock_insecure-kernel.img - (Maybe I've made some mistake in this file. I don't recommend to use this, it can cause some bugs with sdcard0. Better modify it yourself.)
For CM11 based ROM: ext_cm11.img
Great ! Im waiting for this
Bro how can intsall the rom
I m try but couldn't with me
Plz help ??
@SonnySimon this method doesnt work on Stock Kernel/Rom. I will attach stock kernel on XDA today. You can compare mine with yours and update this post. Thanks

[HOW TO] BOOT FROM SD CARD [SUCCESSFULLY] on QMobile Z8 with BRICKED/DEAD eMMC
SimonVN said:
How to convert NAND ROM to SD-EXT ROM for MultiBootloader
Click to expand...
Click to collapse
I have been successfully able to boot from SD card on QMobile Z8 by partitioning SD card on a Ubuntu machine using 'parted' and 'fdisk' commands, replicating eMMC partition table and then flashing factory firmware images to these newly created partitions using 'dd' command. Then I modified "fstab.qcom" & "init.tegra.rc" files in kernel (boot.img) and "recovery.fstab" and "uneventd.rc" files in twrp recovery to initiate mounting and booting from sd card instead of internal memory. It was successful after some experiments. Details can be found here:
https://forum.xda-developers.com/android/help/how-to-boot-sd-card-qmobile-z8-bricked-t3712171
But I have still a few queries to be answered. Please have a look. Any help, comments, information or suggestions will be appreciated.
Hi! I'm a newbie here. I want to ask if the below code is correct for twrp.fstab? Those are the first 5 lines of twrp.fstab.
I change the following lines instead of ".../11120000.msdc0/by-name/system" to ".../11120000.msdc0/mmcblk0p23" and so on.
/dev/block/platform/mtk-msdc.0/11120000.msdc0/mmcblk0p23 /system ext4 ro wait,recoveryonly
/dev/block/platform/mtk-msdc.0/11120000.msdc0/by-name/vendor /vendor ext4 ro wait,recoveryonly

/dev/block/platform/mtk-msdc.0/11120000.msdc0/mmcblk0p24 /cache ext4 noatime,nosuid,nodev,noauto_da_alloc,discard wait,check
PS. My recovery.img was ported using twrp auto porter but it can't mount system, data and cache.
