Hey all, new to xda. Hope I'm not asking stupid questions.
My friend gave me a Galaxy S to fix. Model: GT-I9003.
It has a boot loop problem, cycling the Samsung introduction animation (and sound first time round). The recovery mode didn't work to start with - also trapped in a boot loop.
I followed the instructions here (using Odin3 v1.85) and flashed XXKPE. It seemed to all work fine, but the boot loop remained. I booted it into recovery mode and the following error messages appear.
E:failed to mount /data (No such file or directory)
Click to expand...
Click to collapse
and under -- Wiping data...
E:format_volume: rfs format failed on /dev/block/mmcblk0p3
Click to expand...
Click to collapse
then
Data wipe failed.

From my research I believe it's a corrupted internal SD-Card and is fixed via parted? Could anyone go into more detail on how I would do this?
Many thanks.
I am facing a similar problem on my Galaxy SL... Need a solution too... I would appreciate any help...
Data partition has been corrupted, try flashing userdata.rfs with heimdall. A friend of mine had an stock/untouched phone and this happened to it, even with the corrupted partition i was able to boot cyanogenmod, and tried a lot of things, but nothing worked, it was on warranty, so i flashed back the original firmware and he took it to the service center.
If you want to try do this:
Flash bam kernel PDA_BCK_CF-root_universal_beta14fix.tar (http://forum.xda-developers.com/showthread.php?t=1355675)
Then from CWM flash cyanogenmod (i used cm7, but you can try with cm9)
after that the phone should boot into cyanogemod and give an error on the notification bar
extract the 6 files off the zip i attached and copy them to /xbin
from terminal emulator or adb shell run this for the 6 files:
Code:
chmod 0755 <file>
then run:
Code:
parted /dev/block/mmcblk0 mkfs ext2
When it asks for the partition number, enter 3
finally reboot, and if it worked you can flash a stock rom again, thats it, good luck
My phone boots up, but there are random reboots. Tried a lot of stock and custom ROMs... Nothing works... Warranty expired last week...
Thanks for your time. I appreciate it.

Sorry, I'm very new at this - my first hour doing this kind of thing. Could you explain the procedure in more detail - I would like to learn (make the best of a bad situation).
Am I right to say that the Bam Custom Kernel gives super-root level privileges? Allowing the CWM to fiddle with partions?
I've downloaded the normalboot.img for BCK. How do I flash this to my device? Could you link me to a tutorial?
EDIT: Alternatively could you point me to all the prerequisites I need to properly understand the problem and the methods required to fix it?

I tried that... My phone was booting up...
I have Android SDK on my PC... It includes some tools like ADB.
If your phone is rooted, you can use ADB to do things, like formatting...
Connected my phone. Booted into recovery. From Command Prompt, I went to ADB folder, then typed "adb shell". Then, typed in the parted command, and followed steps. Successfully done...
But the problem continues...
I have found many other users have faced this problem -- http://forum.xda-developers.com/showthread.php?t=1736118
I am disappointed. My phone is no longer in warranty... I am too late...
it is possible that using cyanogenmod and S2E (simple2ext) will work as a workaround until you send it to service center.
grab a copy of s2e and push it to /system/app/
Repartition your External-SD using the same method used for phones with low storage capacity, warning: it will erase all the data in it, so make backups
Start s2e and mark to move:
App and Private app
Applications data
Dalvik and download cache
This makes another partition, and it does not fix data, but at least you should be able to install apps.
I face this problem too. Please someone give us the solution.
Update: I flashed BAM Custom Kernel and put it in recovery mode. Attached it to the computer, but I'm stuck at this error message.
Thanks again.
More information
EDIT: There doesn't seem to be a /data partition at all! I feel I'm getting closer to fixing this.
There are 2 storages chips on this phone, one is mmc and the other is onenand.
I think the mmc chip is dead... it contains both /data and internal-SD, the onenand still works, it contains (system cache and dbdata), you can still use the phone with cyanogenmod if you mount everything that should go on /data on a partition in the external-SD, (the method i described with s2e). However there are some drawbacks, the SD needs to be class 6 or above to maintain the system speed, and the life of the sd is going to be reduced because of the more intensive use.

Thanks. Is there a way to replace the mmc chip without sending it to Samsung?
I've flashed XXFPE then Bam Custom Kernel then when I try install cm7 from CWM it gives:
Checking state of RFS/EXT4...
assert failed: run_program("/tmp/updater.sh") == 0
E: Error in /emmc/update-cm-7.1.0-GalaxySL-Kang-singed.zip
(Status 7)
Installation aborted.
Trying with MIUI instead.
EDIT: MIUI does this too.
How do I get around this? Can't I flash cm7 via Odin like the stock roms?

I think that the problem is when /tmp/updater.sh tries to mount /emmc your internal memory (EDIT: I've just noticed you tried with CM7, so, if I remember correctly, /emmc is the external memory, but I think that the problem is always the impossibility to mount the internal memory.) to backup your /efs directory. Because of the not avaible internal memory (/emmc) it simply exits and aborts the installation.
A simple change in updater.sh will allow you to install CyanogenMod, but wait for a confirmation from alfrix, maybe there's something more.
Anyway here there's a thread of a user with the same problem, he solved this by using the external SD as internal SD, as alfrix suggested.
strange, before touching anything try with the release i used that time (14.12.2011), if it doesn't work, then edit the updater.sh and remove
Code:
if ! /tmp/busybox mount -t ext4 /dev/block/mmcblk0p3 /data ; then
/tmp/busybox umount /data
/tmp/make_ext4fs -b 4096 -g 32768 -i 8192 -I 256 -a /data /dev/block/mmcblk0p3
fi
EDIT: is there any mmcblk on /dev/block?
Code:
ls /dev/block/
Weird the has mmcblk0 reappeared.
Code:
~ # ls /dev/block
ls /dev/block
bml0!c bml6 loop6 ram13 ram9 stl6 tfsr2

I started learning Rom cooking and when I learn that ( more or less ) I am thinking on moving on to theming , CWM cooking ( if that's how it's done ) kernels etc . I used dsixda's kitchen , and so far I made roms for my G Note 2 , my friend's note , wife's flyer .... so i am getting the hang of it ... until I tried making Rom for my Galaxy note n8013 . I am getting status 0 on flash . ( Flashing it with darkman's CWM ) . N8013 being great tablet right out of the box don't need much work . I just want to root it , deodex zipalign theme it a bit and that's it .
I am on windows 8 x 64 usng Cygwin ( FULL Install . ALL options )
This is what I did so far :
I changed api level to 17 for deodexing ,
I extracted recovery.fstab it looks like this
Code:
mount point fstype device device2
/efs ext4 /dev/block/mmcblk0p3
/boot emmc /dev/block/mmcblk0p5
/recovery emmc /dev/block/mmcblk0p6
/cache ext4 /dev/block/mmcblk0p8
/system ext4 /dev/block/mmcblk0p9
/data ext4 /dev/block/mmcblk0p12 length=-16384
/preload ext4 /dev/block/mmcblk0p10
/sdcard vfat /dev/block/mmcblk1p1 /dev/block/mmcblk1
#/modem emmc /dev/block/mmcblk0p7
and followed guide to add device in edify.defs folder
( I beleve it should look like this )
Code:
# Samsung Galaxy Note 10.1 GT-N8013
change_mnt=yes <-- I tried with NO and other combos with fix boot with same results
param1=ext4 <-- I tried changing emmc and ext for param 2 it's a no-go
param2=EMMC
param1_sdcard=vfat
param2_sdcard=MTD
sys_mnt=\/dev\/block\/mmcblk0p9

sdcard_mnt=\/dev\/block\/mmcblk1p1 /dev/block/mmcblk1
modem_mnt=\/dev\/block\/mmcblk0p7
fix_boot=yes
I did everything kitchen tells me to do and at the end it ask me to
convert update script to updater-script
I did that too and voila! Status 0 on flashing
I followed some more guides and PM-d few devs , it all comes to Update binary and updater script , but the guides that I am finding online are
not that clear to noob like me . ( it's basically like you are in the dark and you ask for flashlight , and somebody hands you a flashlight without batteries ) . Any developer that has made n8013 rom , can you share some wisdom , or files ? ( Like updater_script , binary , device support file for edify_defs folder so I can add N8013 to supported devices ) ANY and ALL help is welcome )
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.

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:
.....

#THIS GUIDE IS ONLY FOR ADVANCED USERS, WHO KNOW HOW TO COMPILE AND MAKE MODIFICATIONS TO KERNEL AND MODIFYING VARIOUS PARAMETERS IN RAMDISK IN THE RAMDISK LEVEL #
Hey guys this guide will tell you how to add support for Dual bootinga as primary ROM.
YOU MUST USE ATLEAST CLASS 6 OR ABOVE SDCARD WITH MINIMUM 8GB CAPACITY
First you need 3 EXT4 partitions on SD-card, using minitool partition wizard
1) around 400 MB - SD-SYSTEM (ext4)
2) around 1 GB (or can be less) - SD-DATA(ext4 format),
3)around 75MB (can be less) SD-CACHE(ext4 format) (refer to the screenshot):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
This is very important : You should remove any memory increasing script that you were using. Because /data partition is now on SDcard, using memory increasing script will cause conflict and makes ROM unbootable.
Now making kernel level Changes :
Step 1- open the defconfig of your kernel source and make this change in it
Enable LBDAF (for multiple partitions to work)
Code:
[COLOR="Navy"]CONFIG_LBDAF=y[/COLOR]
Now compile the kernel.
Step 2- Ramdisk level changes:
All modifications are performed on init.rc file.
Step 1- Search for this line :
Code:
mount yaffs2 [email protected] /system
mount yaffs2 [email protected] /system ro remount
Replace it with this :
Code:
[COLOR="Navy"]# Mount SD-SYSTEM
wait /dev/block/mmcblk0p2
wait /dev/block/mmcblk0p2
wait /dev/block/mmcblk0p2
wait /dev/block/mmcblk0p2
mount ext4 /dev/block/mmcblk0p2 /system
mount ext4 /dev/block/mmcblk0p2 /system ro remount[/COLOR]
Step 2 - find this line :
Code:
mount yaffs2 [email protected] /data nosuid nodev
Now replace it with :
Code:
[COLOR="navy"]# Mount SD-DATA
wait /dev/block/mmcblk0p3
wait /dev/block/mmcblk0p3
wait /dev/block/mmcblk0p3
wait /dev/block/mmcblk0p3
mount ext4 /dev/block/mmcblk0p3 /data nosuid nodev noatime nodiratime barrier=0 data=ordered commit=15 noauto_da_alloc nouser_xattr errors=continue[/COLOR]
Step 3- Find this line :
Code:
mount yaffs2 [email protected] /cache nosuid nodev
Replace it with :
Code:
[COLOR="navy"]# Mount SD-CACHE
wait /dev/block/mmcblk0p4
wait /dev/block/mmcblk0p4
wait /dev/block/mmcblk0p4
wait /dev/block/mmcblk0p4
mount ext4 /dev/block/mmcblk0p4 /cache nosuid nodev noatime nodiratime barrier=0 data=ordered commit=15 noauto_da_alloc nouser_xattr errors=continue[/COLOR]
That's it now pack the ramdisk with the kernel you made earlier
All of this is much similar like pll2 Oc by cute_prince.
Now the Updater-script changes
This was the real pain in finding out, It took me nearly a month to figure out how to extract system on the partition, and learn the mount function.. If you are using it PLEASE give me some credits
Step 1- one the updater-script of the ROM find these lines :
Code:
format("yaffs2", "MTD", "system", "0", "/system");
mount("yaffs2", "MTD", "system", "/system");
package_extract_dir("system", "/system");
Replace them with these:
Code:
[COLOR="navy"]run_program("/sbin/busybox", "mount", "-t", "auto", "/dev/block/mmcblk0p2", "/system");
run_program("/sbin/busybox", "rm", "-rf", "/system/*");
package_extract_dir("system", "/system");[/COLOR]
That's it you've Successfully added support for the rom as primary ROM !!
Head Over here : http://forum.xda-developers.com/showthread.php?t=2409236

IF YOU WANT TO PLL2 OC BOTH PRIMARY AND SECONDARY ROMs GO TO THE GUIDE BY @Arslankirmani HERE : http://forum.xda-developers.com/showpost.php?p=45063954&postcount=84
Now if you are using it for adding support for ROM , please PM either me,adityalahiri13 or galaxyfreak the download link so that we can add on the dual boot thread.. IF you are a ROM developer ,i kindly request you to let us also keep the download link for the primary enable ROM.
The Yin-Yang Way!
Procedure
You MUST know how to unpack/repack kernels, and their ramdisks.
If you unpack your kernel, you would find the folder named sbin where you'd unpacked the ramdisk. Place these two files busybox.7z and bootsdcard.txt in the folder. Rename them to "busybox" and "bootsdcard.sh" respectively.
Additionally, you will need to create a folder named "tmp" where you've unpacked the ramdisk.
Now, open up init.rc and find the lines:
Code:
on fs
# mount mtd partitions
# Mount /system rw first to give the filesystem a chance to save a checkpoint
mount yaffs2 [email protected] /system
mount yaffs2 [email protected] /system ro remount
mount yaffs2 [email protected] /data nosuid nodev
mount yaffs2 [email protected] /cache nosuid nodev
After these lines, you are most likely to find these lines (or similar lines):
Code:
# once everything is setup, no need to modify /
mount rootfs rootfs / ro remount
Add the following lines to the above:
Code:
chmod 0777 /sbin/busybox
chmod 0777 /sbin/bootsdcard.sh
exec /sbin/busybox sh /sbin/bootsdcard.sh
En total, it should look like this:
on fs
# mount mtd partitions
# Mount /system rw first to give the filesystem a chance to save a checkpoint
mount yaffs2 [email protected] /system
mount yaffs2 [email protected] /system ro remount
mount yaffs2 [email protected] /data nosuid nodev
mount yaffs2 [email protected] /cache nosuid nodev
on post-fs
chmod 0777 /sbin/busybox
chmod 0777 /sbin/bootsdcard.sh
exec /sbin/busybox sh /sbin/bootsdcard.sh
# once everything is setup, no need to modify /
mount rootfs rootfs / ro remount
Click to expand...
Click to collapse
Now, you can repack the ramdisk, and repack the kernel. In most cases, you should be able to flash the kernel with the busybox included. If you are not able to flash the repacked boot.img, please post the boot.img along with thread from which obtained/sources.
P.S. For the curious, this is what bootsdcard.sh looks like:
Code:
#!/sbin/busybox sh
MOUNT="/sbin/busybox mount"
UMOUNT="/sbin/busybox umount"
MKDIR="/sbin/busybox mkdir"
RMDIR="/sbin/busybox rmdir"
TOUCH="/sbin/busybox touch"
$MKDIR /tmp/sdcard
$CHMOD 0770 /dev/block/mmcblk0p1
$MOUNT /dev/block/mmcblk0p1 /tmp/sdcard
if [ -f /tmp/sdcard/.bootsdcard ];
then
$TOUCH /tmp/.bootsdcard
fi
$UMOUNT /tmp/sdcard
$RMDIR /tmp/sdcard
if [ -f /tmp/.bootsdcard ];
then
$UMOUNT /data;
$CHMOD 0770 /dev/block/mmcblk0p2
$MOUNT -t ext3 -o nosuid,nodev /dev/block/mmcblk0p2 /data
$UMOUNT /system
$CHMOD 0770 /dev/block/mmcblk0p3
$MOUNT -t ext3 /dev/block/mmcblk0p3 /system
$MOUNT -t ext3 -o remount,ro /dev/block/mmcblk0p3 /system
$UMOUNT /cache
$CHMOD 0770 /dev/block/mmcblk0p4
$MOUNT -t ext3 /dev/block/mmcblk0p4 /cache
fi
Now, to switch to the other ROM, please create a file named ".bootsdcard", and to switch to primary ROM, delete the ".bootsdcard" from your sdcard.
I know this post looks wierd, and outta place. the busybox.7z and bootsdcard.sh file can be obtained from here: http://forum.xda-developers.com/showthread.php?t=2413642
until I edit this post...
P.s. @omerjerk made an app for this purpose... he'd release it shortly.
What if?
@ayushrox
U said on facebook that the sd-data is only for primary rom and the data for the secondary rom is on the NAND Partition ....
So , can't we make changes in the boot.img of Secondary Rom so that it uses the SD-DATA Partition for its data ......?
So our apps can be used in both the roms......
ayushrox atleast can you make CM10.1 as primary rom for who dont know how to compile , etc... and please make primary rom support Pll2 OC.
good work!!!!!

I can do this.. but it may cause errors since we can dual boot even GB with 4.3 so the app's a pi level may cause conflict .. but anyways I'll try it

OK I'll add cm 10.1 as primary ROM.with pll2OC ... And BTW devs : u can add pll2OC easily by using the edited acpuclock or editing the ramdisk of pll2 OC Kernels just as I indicated
..
That f*cking awesome!!!!!!!!!!! If we use pll2 oc, does we need extra partition or just partition order on dual boot thread?

nice guide :good::good:
is that CONFIG_LBDAF=y enabled in sense 4.1 kernel cause it uses multiple partitions?
if not can u provide kernel with it enabled
edit : solved
Just signed in, and thought I'd check up on how far you've gotten up to on this project... I think it should be easy enough to adapt the script I made for the HD2 to automate this quicker. I'll put up a file and instructions in a day or two; all being well, if anyone wants to test...
In terms of having the same data file/folder between different ROMs - this isn't something that we managed on the HD2 as there seemed to be permissions issues caused as well as the issue of differnt api levels, it's still worth a try though.
any chance for a noob guide?????

Not a guide but yes.. i'll be posting edited updater-scripts and premade kernels.. for adding support
and guys LBDAF is enabled in all pll2 OC kernels(pandora,aries,etc.) you can take their boot.img ,unpack them,edit the init.rc file as i said and repack it.. and rest the updater-script thing should be easy !!
and @HypoTurtle i thought of giving our script a try..but didn't have time for it.. you can PM me the script , i'll test it
@ayushrox
can u build a kernel that can work with the boot manager app
with it we can boot up to 5 or more roms
is it possible???....
One question. What about gapps for primary rom? If we flash gapps just like that wouldnt they go to /system..! we need then in sd-system!
UPDATE: I compiled a kernel doing the ramdisk changes, enabling lbdaf and also edited updater-script. Formatted the partitions as SD-SYSTEM(EXT4) (455mb)---- SD-DATA(EXT4) (900mb)---- SD-CACHE(eXT4) (85mb)
Rom flashes. But it kinda finishes very early. I checked the sd-system partition using mini partition tool just after flashing and it doesnt seem to have changed..I double checked updater-script. It just stays at HTC logo.

Im trying on my aokp 4.2 build. Yep I did make the changes correctly.. But i think its something with updater-script as it flashes and finishes too soon and i checked sd-system just after flashing rom and the 'used' field is unchanged!

I found that your updater-script was fine.. the problem must be with the kernel.. here's my kernel : http://d-h.st/q91
Download it just take out the boot.img(its named "boot3.img" --rename it to1)boot.img use in rom 2) cm.img (put it in sd-card)
Now, also take the modules part.. then i think it should work fine.. if problem still persistes.. i'll also attach the updater-script !!
And guys the kernel i have uploaded will work for all android 4.2.2 roms .. just use the modules and boot.img
*wifi may not work
and the kernel source is same as mine pandora kernel's
So, I read somewhere that what you've thought, might already have been thought by someone else. Dual-Booting the pico, as most people now know it, isn't something new to this device. When I had made this thread here, most of you might have noticed the init.rc tweak in the post 2. The day before I had written the post, I was experimenting with the possibilities of dual booting my phone, and was successfully able to. How? By changing the mount points, simple.
Now, the problem arises... How many boot.img's do you have to derp? And, how many times would you have to keep flashing your boot partition??? So, I figured out something, which I will be discussing in this thread, which allows you to boot any and any ROM if they both use the same kernel. Therefore, you don't have to flash separate boot.img's everytime you need to change between your primary ROM and secondary ROM.
There is a small change in terminologies:
Primary ROM: The ROM in the internal partition of your device. The name itself is pretty explanatory.
Secondary ROM: The ROM on your SD-Card, secondary, as in second or something like that.

So, how will this help me?
No need to repeatedly flash your boot partition (though it ain't gonna cause any damage).
Easier switching of ROMs.
Doesn't need SU (super user) permissions.
So, all talk no show?
Code:
You seem to be the typical TDLR; case :laugh:
Again, sorry to interrupt you, but there are a few things you'd need to know. First and foremost, this:
Code:

* YOU are choosing to make these modifications, and if you point

*/
Note: If this is to work with Sense 4.0/4.1; or with the new PLL2 OC'ing method, appropriate changes will have to be made, which I would be discussing in later posts. As of now, this method works with all AOSP and derived ROMs, excluding Sense, and those with PLL2 OC'ing.
How it works:
So, this is what most people want to know! Here's how. :angel:
When the device boots, the init.rc is run, if I remember correctly. Here lies the trick. What I planned to do was creating a place_holder in the SD-Card, use it as a, well, place_holder, and execute <insert-awesome-script-name.sh at bootup, which is bootsdcard.sh in this case.
When is bootsdcard.sh run?
After the internal /system, /data, and /cache partitions are mounted.
Click to expand...
Click to collapse
What bootsdcard.sh does?
It basically is an if/else command. If exist /sdcard/place_holder, which is /sdcard/.bootsdcard, in this case, BTW, it unmounts the /system, /data, and /cache partitions, and mounts the partitions on the sdcard in the /system, /data, and /cache folder.
Click to expand...
Click to collapse
So, how to do that?
Here's where I was confused. Checking for file existence, in init.rc? Then, I remembered that some init.d scripts run the same way. Searched the init.rc for /etc/init.d, in vain. Finally, found this thread, and opened up the ROM's zip. There was indeed a file named [Isysinit[/I] in /system/bin/sysinit, and it contained commands to run the files in /system/etc/init.d. What's more important is that the exec commands could be executed using exec /something After hours of searching, I found this: http://forum.xda-developers.com/showthread.php?t=1598803&highlight=dual+boot. Cool! The Samsung Galaxy Y has had dual boot before pico, thanks to irfanbagus. Still, it had a lot of bloat, and couldn't be used directly for our device. So, I saw how it worked, and, it was efficient. So, I decided to port it to our device.
Prerequisites:
Patience ~ Learn it, if you don't have it!
Two ROMs that boot with the same kernel
Linux or Notepad++
file-roller or WinRAR
partitioned sdcard, in the order: fat32>sd-data>sd-system>sd-cache
Procedure:
1. Preparing the ROMs
Get any two ROMs' zip files, which run with the same kernel. Decide which ROM you want as secondary, i.e. in the SD-Card. Now, open up the zip of the ROM which you want in the SD-Card and extract the updater-script from its META-INF/com/google/android/ folder and make the following changes:
Delete these lines:
Code:
format("yaffs2", "MTD", "system", "0", "/system");
mount("yaffs2", "MTD", "system", "/system");
Insert these lines:
Code:
run_program("/sbin/busybox", "mount", "-t", "auto", "/dev/block/mmcblk0p3", "/system");
run_program("/sbin/busybox", "rm", "-rf", "/system/*");
If you feel you aren't doing it correct, please post the updater script of the ROM here. I will edit it.
Drag and drop the changed updater script into the same /META-INF/com/google/android folder. Hopefully, it should be updated within the zip.
Copy these two files to your SD-Card using *any* means possible.
2. Flashing the ROMs
Open recovery, and flash the zip for primary ROM.
Reboot recovery.
Go to Mounts and storage (CWM) or under a similar option, and unmount /data, /cache and /system.
Now, flash the zip you've created for secondary ROM.
If you reboot, you should go into the Primary ROM.
3. Installing modified kernel
You can do this using fastboot too!
Download appropriate pre-derped kernels, or provide the boot.img for derping.
Then, it is pretty simple.
Code:
fastboot flash boot <derped-boot>.img
or via Terminal Emulator
Code:
su
flash_image boot /sdcard/<derped-boot>.img
4. Switching ROMs
Primary ROM to Secondary ROM:
As I said, the place holder. It plays an important role. So, if you want to switch to another ROM, just create an empty file in your sdcard named ".bootsdcard" without quotes. You could also do this via terminal emulator using:
Code:
touch /sdcard/.bootsdcard
Secondary ROM to Primary ROM:
Remove the .bootsdcard from your SD-Card, and you will boot the primary ROM. This can also be done using terminal emulator using:
Code:
rm /sdcard/.bootsdcard
P.S. An application for this is being developed by @omerjerk, to make this easier.
Anything else?

Editing the kernel
Procedure
You MUST know how to unpack/repack kernels, and their ramdisks.
If you unpack your kernel, you would find the folder named sbin where you'd unpacked the ramdisk. Place these two files View attachment busybox.7z and View attachment bootsdcard.txt in the folder. Rename them to "busybox" and "bootsdcard.sh" respectively.
Additionally, you will need to create a folder named "tmp" where you've unpacked the ramdisk.
Now, open up init.rc and find the lines:
Code:
on fs
# mount mtd partitions
# Mount /system rw first to give the filesystem a chance to save a checkpoint
mount yaffs2 [email protected] /system
mount yaffs2 [email protected] /system ro remount
mount yaffs2 [email protected] /data nosuid nodev
mount yaffs2 [email protected] /cache nosuid nodev
After these lines, you are most likely to find these lines (or similar lines):
Code:
# once everything is setup, no need to modify /
mount rootfs rootfs / ro remount
Add the following lines to the above:
Code:
chmod 0777 /sbin/busybox
chmod 0777 /sbin/bootsdcard.sh
exec /sbin/busybox sh /sbin/bootsdcard.sh
En total, it should look like this:
on fs
# mount mtd partitions
# Mount /system rw first to give the filesystem a chance to save a checkpoint
mount yaffs2 [email protected] /system
mount yaffs2 [email protected] /system ro remount
mount yaffs2 [email protected] /data nosuid nodev
mount yaffs2 [email protected] /cache nosuid nodev
on post-fs
chmod 0777 /sbin/busybox
chmod 0777 /sbin/bootsdcard.sh
exec /sbin/busybox sh /sbin/bootsdcard.sh
# once everything is setup, no need to modify /
mount rootfs rootfs / ro remount
Click to expand...
Click to collapse
Now, you can repack the ramdisk, and repack the kernel. In most cases, you should be able to flash the kernel with the busybox included. If you are not able to flash the repacked boot.img, please post the boot.img along with thread from which obtained/sources.
P.S. For the curious, this is what bootsdcard.sh looks like:
Code:
#!/sbin/busybox sh
MOUNT="/sbin/busybox mount"
UMOUNT="/sbin/busybox umount"
MKDIR="/sbin/busybox mkdir"
RMDIR="/sbin/busybox rmdir"
TOUCH="/sbin/busybox touch"
$MKDIR /tmp/sdcard
$CHMOD 0770 /dev/block/mmcblk0p1
$MOUNT /dev/block/mmcblk0p1 /tmp/sdcard
if [ -f /tmp/sdcard/.bootsdcard ];
then
$TOUCH /tmp/.bootsdcard
fi
$UMOUNT /tmp/sdcard
$RMDIR /tmp/sdcard
if [ -f /tmp/.bootsdcard ];
then
$UMOUNT /data;
$CHMOD 0770 /dev/block/mmcblk0p2
$MOUNT -t ext3 -o nosuid,nodev /dev/block/mmcblk0p2 /data
$UMOUNT /system
$CHMOD 0770 /dev/block/mmcblk0p3
$MOUNT -t ext3 /dev/block/mmcblk0p3 /system
$MOUNT -t ext3 -o remount,ro /dev/block/mmcblk0p3 /system
$UMOUNT /cache
$CHMOD 0770 /dev/block/mmcblk0p4
$MOUNT -t ext3 /dev/block/mmcblk0p4 /cache
fi

Adding support for G-Apps
You'd also need G-Apps for your secondary ROM. Here's how-to:
Open up any G-Apps zip, and extract updater-script from META-INF/com/google/android folder.
Find the following line:
Code:
run_program("/sbin/busybox", "mount", "/system");
Replace it with:
Code:
run_program("/sbin/busybox", "mount", "-t", "auto", "/dev/block/mmcblk0p3", "/system");
That's it! You can flash your modified g-apps for secondary ROM.
Reserved
In case the boot.img doesn't flash after re-packing, it is very likely that there isn't enough space in the boot partition. I will add the procedure, for that case too.
finished post, reviews welcome
another one , good work bro :good:
is it possible to dual boot Thinkingbridge and stock ??
how about memory scripts ? will it work on both primary and secondary roms !!!

Not possible by the Yin-Yang. One prerequisite is that both the ROMs should use the same kernel.
You could try the other method by ayushrox, which involves using separate boot.img's with different mountpoints.
Memory increasing scripts? That's easy, but you'd need four ext3 partitions, and a modified int2ext. Procedure:
format sdcard in following layout:
fat32>sd-data>sd-system>sd-cache>sd-ext.
Open the memory script int2ext, or int2ext+, and change the following:
Use the search and replace function, it would be helpful.
Replace:
Code:
/dev/block/mmcblk0p2
With:
Code:
/dev/block/mmcblk0p5
