[Completed] Help needed with rom development!!! - XDA Assist

Hey guys. This is my first post to XDA Developers. But the most important thing is that --- I AM A NOOB
I am making my first ROM for Moto E 1st gen. I just wanted to mod some files. I had CM RESURRECTION REMIX 5.1.1 on my moto e. So i took a nandroid backup and extracted all the files. After all modding, I removed all text in updater-script as the script was for system.new.dat format. And i then added a new updater script from Android Script Creator and saved it. And then i used dsixda's Android Kitchen For zipping the file and zipaligned all the apps. But when i flash the rom after wiping system,cache,data,internal storage--- I get error while flashing
Code:
mount: failed to mount /dev/block/platform/msm_sdcc.1/by-name/system at /system :Device or resource busy
First everything goes well It detects the file system but fails to mount:crying: and at end it gives
Code:
output script succeeded:result was [/system]
Updating Partition Details
and TWRP says flashed succesfully ! BUt when i reboot it boots to bootloader and Fastboot reason says- Fall-through from normal boot mode
Anybody? Please help me !! This is killing me now!

SCROLL DOWN to 2nd POST FOR THE WHOLE GUIDE...
GUIDE
So here is the full guide:
PARTITIONING SD CARD TO MOUNT /SYSTEM AND /DATA
Take the backup of your sd card data first
Make sure you have partitioned your sdcard before.
Connect your phone to your computer and mount usb storage.
Download the EASEUS partition manager from here.
Open partition manager and delete all partitions of your sdcard.
Right click on the 'unallocated' and click create partition.Don't label it select partition type as primary and filesystem as FAT32 and enter the partition size bot remember this will hold your photos,media etc,you should leave about 600 mb space free click OK.
right click again and create partition as primary and filesystem as EXT3 and size of 250 mb click OK.
Repeat above step again.
Apply all the changes by cliking on apply tap and you have succesfully partitioned your sdcard for dual booting.
​
GUIDE FOR THE TOOL
Extract the downloaded zip file extract to any concinient directory.Here I will explain the guide as a cygwin user.
Extract the zip to directory say c:\
The extracted folder will look like 'Modify-boot".Now open the terminal or cygwin bash and mount the directory by typing
cd c:\modify-boot
Click to expand...
Click to collapse
Now drop your boot.img in the WORKING_313 folder and execute the script by typing
./modify-boot.txt
Click to expand...
Click to collapse
It will mod your boot.img for dual booting.Output boot.img will be in the WORKING_313 folder as boot.img.
MODDING THE ROM FOR DUAL BOOTING
Open the ROM.zip.
Get the modded boot.img from the tool and replace with the original one.
Now download the attached updater-script from 1st post and replace the orignal one with this modded one(path to udater-script META-INF/com/google/android).
Zip up the rom.
ADAPTING A ROM TO INSTALL IN THE SD CARD
If you want to mod your own rom other than the posted here,then you have to mod the updater-script in the rom
For that open your rom zip go to /META-INF/com/google/android and open the updater script
Now replace every line looking like following as;
From
mount("yaffs2", "MTD", "system", "/system");
Click to expand...
Click to collapse
TO
run_program("/sbin/mount", "dev/block/mmcblk0p3", "/system");
Click to expand...
Click to collapse
and this one
From
format("yaffs2", "MTD", "system", "0");
Click to expand...
Click to collapse
TO
run_program("/sbin/mkfs.ext2", "dev/block/mmcblk0p3");
Click to expand...
Click to collapse
and add the following line next to the line written above
run_program("/sbin/mkfs.ext2", "dev/block/mmcblk0p2");
Click to expand...
Click to collapse
Save the file and zip up the rom.Your rom is ready to install to SD CARD!!!!
FLASHING GUIDE
Remember, before partitioning the sd card you should wipe data and cache in the recovery during NAND rom installation or it will erase the partitions created before.
First flash the rom you want to install in the NAND,do not wipe data or anything do it before partitioning.
Then install the rom without wiping data or anything.
reboot the system. You will be in your sd card rom!!!
Now create folder in the sd card as /sdcard/multiboot.
Take both boot.img from NAND rom and cm9 rom rename the cm9 boot.img to bootsd.img and keep the NAND boot.img as it is.
Copy both imgs to multiboot folder.
Now download attached(or use above link for unregistered users) bootnand.sh and bootsd.sh and place at the root of the sdcard.
Open terminal emulator,type su and execute bootsd.sh to boot into sd card rom or execute bootnand.sh to boot into NAND rom.
THAT'S IT . ENJOY DUAL BOOT ON YOUR ZTE BLADE!!!!

I've found that making four partitions and installing /data to mmcblk0p4 and /system to mmcblk0p3 helps with certain roms that have S2E configured.
I'm also trying to get it to boot two mounted loop filesystems instead, i installed SSRLS7 and GB-Gapps as per your instructions in the OP (just changed the partitions for installation and the updater-script and init.rc so that it would work) did a dd of the entire partitions to files on the sdcard and edited the init.rc like this:
Code:
on fs
# mount mtd partitions
chmod 777 /sbin/busybox
symlink /sbin/busybox /sbin/losetup
mount vfat /dev/block/mmcblk0p1 /mnt/sdcard
losetup /dev/block/loop0 /mnt/sdcard/multiboot/snow/system.img
losetup /dev/block/loop1 /mnt/sdcard/multiboot/snow/data.img
mount ext2 /dev/block/loop0 /system
mount ext2 /dev/block/loop1 /data
mount yaffs2 [email protected] /cache nosuid nodev
on post-fs
# ZTE_JCD_CTSCONFIG, 2011.05.03, BEGIN
mkdir /system/lost+found 0770
chmod 0770 /system/lost+found
# ZTE_JCD_CTSCONFIG 2011.05.03, END
# once system is setup, no need to modify /system , ZTE_BOOT_LIWEI_20110331
mount ext2 /dev/block/loop0 /system ro remount
I also copied busybox to /sbin in the ramdisk before letting the process finish and make bootsd.img
It doesn't work though and i have no idea why not. I've mounted the system.img and data.img files on the phone via the terminal to test if the procedure works and it does mount them just fine.
If anyone has any clue why this doesn't work then please tell me.

Actually, it'll work on any phone that runs android and has a working recovery that can be used to install boot.img and system files via an updater script.
It works fine on my Mini and Huawai G300.

[DUAL_BOOT][ANY_ANDROID]Dual booting in an android phone with external SD card

So here you come. To read and perform this tutorial, you obviously need a first hand experience on flashing a ROM and/or kernels. Otherwise this tutorial and my efforts to get you a device with two OSes running might end up giving you a bricked device. So, if you're hearing the terms "flashing" or 'kernels' for the first time and thinking it's kinda good food, then bro, just go and taste those first.
Something's to remind before we gonna dig deep into this tutorial->
Noone but you will be responsible for what you end up with.
The warranty of your device will be voided after this if it isn't already after rooting. For MI users, the good news is that you can reclaim it by just flashing the fastboot ROM for your device.
Enough lectures. Bro let's get to work.
Things you'll be needing =>
One working Windows PC(because I doesn't know any replacement of bootimg.exe on any other OS. If you know, then let me).
ADB, fastboot and the device drivers (easily found in XDA)
Any custom CWM based recovery installed.(since TWRP is most popular, I will demonstrate using it. You can use any other you want overall process will be the same)
A custom ROM and kernel for your phone(the second os)
A class 10 memory card ( I recommend 32GB for the spaces)
PART 1: MODIFYING THE BOOT
At first, how does your device boots up? What are the partitions called /data and /system? The answer is quite simple. It's your kernel that points out the location from where the OS should be picked up. So for booting into the second OS we need some modifications to it at first.
Search and download bootimg.exe on XDA, I'll post a link later. Create two folders. Name them "Internal OS" and "External OS" respectively. Put the zip file of the OS you're currently using to the first one and the OS you're gonna use on the external storage to the second one. Rename the second OS to originalExternalOS.zip. Extract originalExternalOS.zip. Pick the boot.img file from the root of the extracted folder and move it to a new folder named "boot2". Extract the IMG using bootimg.exe. Navigate to the initrd folder and you will get a file named 'fstab".
Basically it's the file that tells the kernel which partition does the OS resides in.
Open the file in your favourite text editor.
Replace every instance of the first line with the second one:
/dev/block/bootdevice/by-name/system => /dev/block/mmcblk1p2
/dev/block/bootdevice/by-name/userdata => /dev/block/mmcblk1p3
/dev/block/bootdevice/by-name/cache => /dev/block/mmcblk1p4
Save the file without giving any extension to it. Repack it using the same tool. You'll have boot-new.img and boot-old.img. Rename boot-new.img to boot.img and replace the one in the root folder with this. Basically what we're doing here is replacing the old boot.img with the modified one.
For your knowledge, blocks are the partitions of any storage you have on your device. For example, your internal storage is partitioned to near about 30 different blocks each starting with prefix "mmcblk0p". We here just told the kernel to load the OS from the blocks mentioned. We'll be creating these blocks in the external SD card next.
PART 2: PARTITIONING THE SD CARD
Connect your device with the memory card inserted to your PC. If you haven't installed fastboot, ADB, and the drivers, do it now.
READ THE FOLLOWING CAREFULLY
Reboot the device to recovery mode. Type the commands in cmd:
Code:
adb shell
parted
unit MB
print
quit
umount external_sd
Read and store the minimum and maximum capacity of your card. Since different cards will have different capacities I will point it as variable MIN_SIZE and MAX_SIZE. You'll need to calculate and put the values in the commands. Now type the following commands on cmd:
Code:
parted /dev/block/mmcblk1
rm 1
//START_BLOCK = MAX_SIZE - 5000
mkpartfs primary fat32 MIN_SIZE START_BLOCK
//SYS_START = START_BLOCK+1
//SYS_END = SYS_START + 1200
mkpartfs primary ext2 SYS_START SYS_END
//DATA_START = SYS_END+1
//DATA_END = DATA_START + 3500
mkpartfs primary ext2 DATA_START DATA_END
//CACHE_START = DATA_END + 1
mkpartfs primary ext2 CACHE_START MAX_SIZE
//We have partitioned the memory card. Let's format them. Ignore all "Do you wish to continue" question in the next commands as we're already mentioning yes.
mkfs yes 1 fat32
mkfs yes 2 ext2
mkfs yes 3 ext2
mkfs yes 4 ext2
quit
//Now they are almost ready. Just make the newly created blocks readable by the OS.
make_ext4fs /dev/block/mmcblk1p2
make_ext4fs /dev/block/mmcblk1p3
make_ext4fs /dev/block/mmcblk1p4
//Now you get where does the blocks come in the kernel right?
exit
//You've covered up the hardest part. Let's get some coffee.
PART 3: MODIFYING THE NEW OS
You've left the OS extracted in the "External OS" folder right? It's time to do some magic in it. We're gonna tell the OS to be installed in the blocks we created just like the kernel. But wait, where does the OS know before installing where it should get installed? Well, the answer hides in the updater-script in the folder META-INF > com > google > android. Navigate yourself in it. Open the updater-script file in your favourite editor ( I use notepad++ ) and modify it in the same way as the boot.
Replace every instance of the first line with the second one:
/dev/block/bootdevice/by-name/system => /dev/block/mmcblk1p2
/dev/block/bootdevice/by-name/userdata => /dev/block/mmcblk1p3
Leave the /dev/block/bootdevice/by-name/boot as it's the fundamental block and we can't replicate it. Don't think for the /cache partition as we've already done that in the boot.img file. Now navigate to the root of the folder where you extracted the External OS. Select all files, add them to a zip file using WinRAR. Name the file to newOS.zip. Open newOs.zip and originalExternalOS.zip with WinRAR and compare them if you find any change in the folder tree. They must and they should be exactly the same. You're 80% done.
PART 4: MODIFYING THE RECOVERY
We often flash many zips including very popular Xposed and other mods to our OS right? They also look for the /system partition. So what are we gonna do? Modifying each of them? Nah. Let's modify where they get which one the /system is. The recovery. Extract the img of the recovery you're using with the same bootimg.exe. Modify exactly the same things. I.e.
Replace every instance of the first line with the second one:
/dev/block/bootdevice/by-name/system => /dev/block/mmcblk1p2
/dev/block/bootdevice/by-name/userdata => /dev/block/mmcblk1p3
/dev/block/bootdevice/by-name/cache => /dev/block/mmcblk1p4
in the following files : initrd/fstab.qcom
initrd/etc/recovery.fstab
initrd/etc/twrp.fstab(For TWRP only)
Save them. Repack. And you got your recovery-new.img and recovery-old.img. Put recovery-new.img and newOS.zip in the same folder. Now wake up, it's time for some action.
PART 5 : INSTALLING THE OS
Open cmd in the folder where newOS.zip resides. Reboot the device in fastboot mode. Type the following commands:
Code:
adb push newOS.zip external_sd
fastboot flash recovery recovery-new.img
fastboot boot recovery
Now your device should boot up in recovery mode. To check if everything has gone fine mount system using TWRP. Use twrp's built in file manager and navigate to system folder. It's empty? Yup. You've done a great job. Now flash the newOS.zip using TWRP and your device should boot up in the new OS. To cross check again remove the SD card and try to boot. If you're headed towards recovery or bootloop after that then it's a win. Put the SD card back again and watch the new OS to boot.
PART 6: SWITCHING BETWEEN THE TWO
Extract the boot.img from the "Internal OS" zip file and put it together with recovery-old.img. To check if your old system is untouched type the following commands in fastboot mode:
Code:
fastboot flash recovery recovery-old.img
fastboot flash boot boot.img
fastboot boot system
Your device should take you back to the old one. Surprised? Now let's make a switch between the two. There are two methods.
METHOD 1: USING FLASHIFY
Create two folders in your SD card. Put boot.img and recovery-old.img to one and boot-new.img and recovery-new.img to the other. To switch to the external OS, just flash boot-new.img as boot and recovery-new.img using flashify. Ignore reboot now dialog and reboot directly to the system. To go back, first install flashify in the new OS and flash boot.img and recovery-old.img. Easy right?
METHOD 2: USING ZIPS
I'm gonna tell you that tomorrow as I can write no more today.
More to come....

Yeah I Know I Can Try But i Need To Know Method 2 To Switch ROMS Because Second One Is Faster Using Zips Otherwise Great Post And Guide ,Thank You
Good Luck With Your Exams
Nice tutorial.
Dual boot for Mediatek devices is so easy to me. But I don't have any idea for Other devices like Samsung or Sony.
When I bought some SD Card, I'll try this one.
Keep it up!

Thanx a lot
BTW flashify is also very convenient method
1)Just choose boot image from the option
2)Find and select the internal or external boot image to boot
3)Have a normal reboot

I am gonna try this anyway, maybe tomorrow
Because i want two ROMS mainly, one for CM cuz i love it, daily drivers and everday usage, second one mainly focused on battery life (when i don't use my device much)
Another Question ,How do I Flash Zips (from recovery) To A Specific ROM?
And I Have CM 12.1 And Im Using M5 Kernel so Where Do the Edit Goes?

The edit goes to the recovery. At the end of the process you'll have two different recovery files for two OSes. Flashing any zips via modified recovery will flash them straight to the new os. Switch between those recoveries as required. Read the TUT carefully.

I am getting the same error as this, what should I do to fix it?
Have installed python v2.7.13+3.6.1, latest java jdk and jre and .NET framework v4.7 and running windows 10, it had worked on the first try but started showing this error suddenly.
It works, but after install ROM the battery discharges very quickly and heats up... I think that incorrectly exposed file permissions, because if i flash "system" folder with setting simlinks and set_metadata in updater-script ROM works fine and battery is ok.
ROM work only with system.img, system.new.dat dont flash, error 7 in TWRP...
best tools ,thanks!!

The link is not working.
You need to have a custom ROM, and in it system.transfer.list and system.new.dat.
Use this method:
[DEV] sdat2img 1.0 - img2sdat 1.2 ◦ Unpack/re-pack android DAT files
For a long time I use and have not found Android ROM 5.1.1 - 8.0.0, which can not be unpacked using sdat2img.py.
Thank you authors @xpirt , @luxi78 , @howellzhu !
You dont need a custom rom or the system.transfer.list, or system.new.dat. This unpacks images just fine. It will not unpack factory images tho. I got it to work just fine unpacking nexus 6 system.img by placing the image in the output_converted_dat_to_ext4 folder then telling the bat file what the size is and unpacking it. Do the same thing for oreo and the ext4 exe crashes.

rom isn't booting after editing system.new.dat. any help ?
For anyone having syntax errors converting systemsparse.img to system.new.dat just download the updated img2sdat files from the link below and extract all files ending in .py to the tools folder of this batch tool. There's also an updated sdat2img.py linked below which goes in the same tools folder. Overwrite all the old files when prompted.
Edit: I've attached a zip that has the tools already updated. Maybe the OP can update the first post?

[Guide] [SC8830/SC7731/SC9830] Custom Recoveries Porting guide for Spreadtrum phones.

Code:
[CENTER][COLOR="Red"]Your warranty is now void.[/COLOR]
I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research before asking help and reporting bugs and please read the entire OP.
YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you.
A lot.[/CENTER]
All suggestions and helps are welcome here so please help me in improving this thread by suggesting your ideas.
This guide will work for any SPRD phone (any SPRD chip) from Old versions of android to latest Oreo but recoveries that I provided in this thread will work for devices from KitKat to Marshmallow no guarantees for older or newer versions.
Buckup! Backup! Backup!​
Before modifying system it's highly recommended to have full dump of your device. So don't forget to take backup.
It's simple to get custom recovery for rooted users as they can directly backup, modify and flash recovery or boot images on the go with the help of root. But non-rooted users need to do some extra which will be explained later. Follow the below steps:
=>Download and setup AIK (Android Image Kitchen)
=>Grab your stock_recovery.img
For rooted users​Install Flashify, Rashr, Partitions Backup or like apps (available on play store for free) and backup the stock recovery. If you are using Flashify to backup you have to rename the backed up image with .img extention
For non-rooted users​Download your stock firmware which will be in .pac extension extract it using this guide and copy the recovery.img
=>Now download custom recovery (for downloads see 2nd post)
=>Port recovery
For PC version of AIK​
• Extract the AIK on desktop in a folder (extracting inside other folder(s) is not recommended)
• Place stock_recovery.img (use the name recovery.img only I added stock to refer the image) in earlier extracted folder
• Now double click on 'unpacking.bat'
• Now you'll see two folders 'ramdisk (mostly executables)' and 'split-img (kernel to boot recovery) rename those folders like this 'ramdisk.s' and 'split_img.s' (renaming is used to avoid copying/moving needed files)
• Now delete the earlier pasted stock_recovery.img and paste custom_recovery.img (rename it to recovery.img)
• Unpack it just like stock_recovery
• Delete the split-img and rename the 'split_img.s' to split_img
• Open recovery.fstab from /ramdisk.s/etc (stock recovery's fstab) and /ramdisk/etc (custom recovery's fstab) using Notepad++ or with your favorite note editor. In case of TWRP recovery this file will be named as twrp.fstab if there is recovery. fstab you can ignore it.
• Edit the partition names and mount points in custom recovery with your stock recovery's fstab. But in most cases the mount points will be shown like this 'mmclbk0p17 for system partition' in that case you need to change custom recovery.fstab with the mount points of your device, to find out mount points of partitions install Diskinfo from play store and enable all options in it which will show complete information regarding each and every partition on your device
• At last double click on 'repackimg.bat' now you'll see 'image-new.img' which is ported custom_recovery.img for your device
• The final step is flashing the recovery. It's easy for rooted users simply use Flashify app to flash. For non-Root users you need to flash it over fastboot mode for this look at this thread.
For mobile version of AIK​
You can also port the recovery on-the-go using AIK-Mobile unfortunately to use this needs your device must be rooted with BusyBox (Stephen (stericson) is recommended) installed.
It's a flashable zip but you can extract the zip and place the files manually. Follow below steps for setup:
• Extract the AIK-Mobile.zip
• Paste the AIK-Mobile folder under data/local of extracted zip to /data/local
• Paste files under /bin of extracted zip to /data/local/AIK-Mobile/bin
• Make sure all files including folders are having these permissions "-rwrx-xr-x-".
For placing files, changing permissions and executing scripts 'Explorer' by speed software is recommended.
For porting follow above steps (steps in PC version of AIK) the only difference here is .bat files of PC version will be as .sh in mobile version which are to be executed as root for unpacking and repackaging images.
Note:Follow the instructions properly, don't quote entire OP while asking for help. Due to some touch related drivers missing in kernel of recovery in some devices touch recovery won't work in that case please use Non-Touch recovery. In lollipop or later versions don't flash <3.x.x versions which may result in SD card mounting issues and even flashing errors. First test the recovery that you ported by flash a simple mode (I prefer AIK-Mobile since it doesn't modify the system partition hence there is not chance of bootloop. Also see whether wipe options works properly or not in some devices wiping (even cache) takes ~10m in that case goto settings check the option "use rm -rf instead of formatting".
Hit thanks button instead of posting thanks it'll boost me to create more threads like this.

you wrote that delete only split_img.s.....

Is there any problem will arise when repacking with ramdisk.s with ramdisk and split_img of custom recovery?

Read again carefully you have to pack custom recoveries ramdisk with stock split_img and reversing the process will mess up the recovery and then you have to flash the stock recovery. So read the guide carefully step-by-step and follow the process exactly unless you know different working method.

Give it a try it may work. But none of the recoveries that are provided here will work for your device, you need to find Android 7.0 and later recoveries which will be compatible with your chipset model.

TWRP has nothing to do with boot.img. If you are not able to boot to recovery try different key combination. Is you messed up recovery too then flash it via fastboot and then flash the stock Rom.
