[Q] How to make a system folder into a system.img - GT540 Optimus General

Hello XDA, I'm kind of new to ROMs etc. and would appreciate some help. I am trying to install mikegapinski's 2.3.7 ROM (v5) through fastboot and whereas in the past I have seen a boot.img and a system.img, there is a boot.img and a system folder. Is there a way to make the folder into a system.img file that I could flash onto my GT540?
In short, how do you make a system.img file out of a folder with system files in them?

hey there !
(system.img + boot.img) is for fastboot
fastboot flash boot boot.img
fastboot flash system system.img
and the (system folder + boot.img) is for recovery
use any recovery
select zip from sdcard
select the zip
i dont think you can convert the folder to a .img(or the other way around) . and if the rom you are talking about mike's aosp v5 then i wont recommend it as for now there are problems with the ram and so it becomes very laggy. i would recommend mur4iks swiftdroid asis but the choice is yours

I know you can 'extract' images using 'unyaffs' but I never made an image from a folder (except when dumping partitions). I think there is a way though.

If you have Linux on your PC, then you can use the 'yaffs' tool. Search it on Google.
This is how even AOSP compiles system folder into system.img

I got it. If you use Linux, you can create an iso file of the system folder, and then convert it to .img. Just follow it:
In a terminal(CTRL+ALT+T):
Code:
mkisofs -o /path/to/the/system/folder ~/system.iso
dd if=~/system.iso of=~/system.img
rm ~/system.iso
Your system.img will be on your home directory.

and it work's too ? (when you flash it from fastboot)

pls if you find a solutuon please pm me. And do you think flashing the system.img will solve booting probz?

suggestion
take a look at this url, and examine the zip file contained.
you could boot into cwm and install the zip (not suggesting, its what i did)
if u make a zip file in the same layout you could install your zip and it will update the system partition.
as you have a desire, heres whats required
on phone: place phone into fastboot mode
on computer: unzip to a folder , place the img file in such folder,
open a command prompt, (navigate to folder using the cd command)
and type: fastboot boot bravo-cwm.img
mount sd card, toggle usb storage, place your zip in root of sdcard.
then untoggle, go back, select option to install zip from sdcard.
choose select zip file.
find your zip.
tap on the file, and it will install...
you SHOULD by this point have an updated phone as you desired (lol)
if it does not work as you expected, have a look for a standard system.img for your phone, and put that into a zip
name the zip (i put it in caps, weather needed i dont know) PM99IMG.zip
place it into root of sdcard, and put phone into the first screen of recovery menu, the white screen.
it will analyze your zip and ask you to install, press up to flash and then the required option to reboot when its done to revert your phone back to normal.
hope this helps there buddy,
ill most likley forget to check back, so if u need any help pm me and ill see what i can do,

Is this working

Quick rom customization question

Im trying to add some ringtones and apps into one of my favorite roms so things will be a little easier when Im testing out other roms...I think the new zip file I make though needs to be signed. Can anyone point me into the right direction??
Amon_RA said:
You can get any custom ROM working on your Rogers Magic and basically on every HTC branded Magic around. If you like to "port" a custom Google-branded ROM to a HTC-branded ROM follow these steps :
- I assume that you have basic Linux knowledge and that you know how to set up your own environment and tools, unpack gz files and cpio them etc...
- Download these tools. They contain the JesusFreke's SignApp, William Enck's splitboot using my recompiled mkbootimg-H binary (including the HTC branded offsets), and a repack pearl script.
Now the actually work :
1. Get the boot.img and recovery.img from your original HTC branded Magic (fastboot my recovery image and use nandroid for this).
2. unpack the boot.img and recovery.img using unpack-H.pl.
3. move both kernels somewhere save, you'll need them later.
4. Download the google branded custom ROM you want to port, most of the custom ROMs come in the form of a update.zip file.
5. Extract the boot.img and recovery.img (if there is one) from the update.zip.
6. unpack the boot.img and recovery.img (same as step 2).
7. replace both kernels with the ones you saved previously in step 3.
8. repack boot boot.img and recovery.img using repack-H.pl
9. copy both boot.img and recovery.img in the update.zip package making sure you overwrite the existing ones inside with the new ones.
10. Sign the update.zip file with SignApp (see readme inside rar).
11. Copy the update.zip file to your SDcard.
12. fastboot my recovery image and choose data wipe and then update.
13. reboot
Good luck

This is where I get confused at. I read this "Usage:
java -jar signapk.jar testkey.x509.pem testkey.pk8 <update.zip> <update_signed.zip>" But I dont know how to do that...Im using OSX right now is there any way to do it or do I need linux?
Can anyone give me some advice??

[UPDATE 22/08/12] ROM Cooking Guide (One Package)

This is how I made ROM, I'll try to write the steps as simple as I can. For advanced users only!
Update 22/08/11:
Revised packaging steps.
Update 13/08/11:
Removed unwanted method for ROM cooking.
Update 04/08/11:
Modified extract and repack ROM guide and added extracting system.rfs guide.
Things you need:
Base firmware
Archiver software (7zip recommended)
Any Linux environment to build ROM or Cygwin
APK Manager to optimize and decompile *.apk files
MagicISO (Optional) if you want to extract system.rfs
And the last thing is... You need enough experience in android world
So, here is the steps to cook a ROM:
Flash your phone with your desired base firmware
Make required modifications
Pull system.rfs from your phone by running this command on adb shell or Terminal Emulator:
Code:
dd if=/dev/stl12 of=/sdcard/system.rfs
Extract any *.tar.md5 files from your base firmware to your working folder with 7zip
Replace the current system.rfs with your modified one
EDIT: Pack your ROM by running this code via terminal or just pack it with 7zip/WinRAR as *.tar
Code:
tar -H ustar -c * >> ROMNAME.tar
change ROMNAME to your desired, well, ROM name.
Here is (yet) useful guide to modify your ROM.
Extract system files on system.rfs to make modding easier:
Extract PDA file (*.tar.md5) files with 7zip
Open system.rfs with MagicISO
To extract it, just drag and drop
NOTE: Never edit your ROM with MagicISO because the file permissions will be ignored, use MagicISO only for extracting files from system.rfs
Deodex, and Zipalign (optimize) your ROM apk files:
Ready to use deodex + root for KPN: http://forum.xda-developers.com/showthread.php?t=1196230
Ready to use deodex + root for KPH and other firmware: http://forum.xda-developers.com/showthread.php?t=1118048
Open APK Manager
To zipalign your apk files, in apk manager folder /place-apk-here-to-batch-optimize put your:
framework-res.apk, twframework-res.apk and all system apk
but not these:
AxT9IME, Calculator, Camera, Email, MMS, Phone, Screen Capture, Settings, Swype, Thinkdroid, Voice search
Choose Choose option 15
Then choose both (zp)
Let it run and done.
Now put back the apk files where they belong in the ROM.
How to put these apk files to my ROM? Copy these files to appropriate locations, such as /system/app to your ROM's /system/app, and etc.

As Linux, MagicISO read RFS image as a FAT filesystem. File permissions can not be maintained. A better way but need linux:
1. Mount system.rfs as FAT and mount it to /tmp/rfs
2. Make ext4 image, and mount it to /tmp/system
3. Copy /tmp/rfs contents to /tmp/system
4. Make modification inside /tmp/system
5. Fix file permissions inside /tmp/system
6. Umount both image
7. Make ODIN flashable image, contains system.rfs (now in ext4 format) and CF-Root-S5830 boot and recovery image (for ext4 support)
8. Boot to Windows and flash your new firmware using ODIN.

[Tutorial] Add TWRP to AOSP LP 5.0 boot.img

I've updated the boot.img for paxb build 504 with TWRP to replace CWM. Some were asking how to do this.
Always keep a backup of a file known as working. If your device doesn't boot after flashing a modified file, just reflash that backup.
To perform this mod on your own follow these steps:
1. Download and unpack the Android Image Kitchen
2. Extract the boot.img from the downloaded ROM to the kitchen directory
3. Unpack the image:
Code:
unpackimg.bat boot_cwm_pabx_504.img
Output:
Code:

BOARD_TAGS_OFFSET 00000100
Unpacking ramdisk to "/ramdisk/" . . .
Compression used: gzip
9694 blocks
Done!
This process will overwrite previously extracted contents!!!
4. Create a directory for the original image content, e.g. "boot_cwm_pabx_504" and COPY the created directories "ramdisk" and "split_img" into it. This ensures you can recreate it if necessary or access its original contents
5. Repeat step 4 for a downloaded TWRP (or any other recovery) image, e.g. "openrecovery-twrp-2.8.0.1-yuga.img".
6. Locate the "*-ramdisk.cpio.gz" file in the dirs from step 5, most likely in "split_img".
7. Ensure the "ramdisk" and "split_img" directories in the kitchen root dir are those from the image you want to modify (i.e. copy back from the folder created in step 4. Then remove the "*.cpio" from the "ramdisk\recovery" directory
8. Extract the TWRP "*.cpio" file from the "*-ramdisk.cpio.gz" in step 6 to "ramdisk\recovery" and rename it to "ramdisk-recovery.cpio"
9. rebuilt the image with the updated content:
Code:
repackimg.bat
Output:
Code:

board =
base = 80200000
pagesize = 2048
kernel_offset = 00008000
ramdisk_offset = 02000000
tags_offset = 00000100
Building image . . .
10. Step 9 creates a file called "image-new.img". Rename it to something more self-explanatory, i.e. "boot_twrp_2.8.0.1_pabx_504.img"
11. To flash the file flash it like any other file using the new name:
Code:
adb reboot bootloader
fastboot flash boot boot_twrp_2.8.0.1_pabx_504.img
fastboot reboot
That's it, enjoy your new recovery.
Note: I had issues getting TWRP 2.8.1.0 working, so I'm still using the predecessor 2.8.0.1.
The latest pabx "boot.img" modified with TWRP is attached.
Known issues
after restoring a Nandroid backup access to the internal storage isn't allowed anymore
Open a terminal or run through a adb shell:
Code:

Thank works dobře.TWRP I like long ....
cant understand what you mean in step 7 and 8..... i just unpacked boot.img (the img that i want to put a recovery on it) and then i created a folder and i copied split_img and ramdisk into it.....then i unpacked twrp.img and it replaced the previous split_img and ramdisk folders with the twrp ones..... i still have the folder i created with the original split_img and ramdisk folders from boot.img but i can understand what to do next....
well, sorry for that,...i think i got it now that i read it about 20 times..... one question though :
i copy ramdisk.cpio.gz from the twrp and i move it to the recovery folder of the boot img without extracting? just renaming it from ramdisk.cpio.gz to ramdisk-recovery.cpio ???

Yeah I didn't fully understand that either, but i just tried it.
You delete ramdisk-recovery.cpio from /ramdisk.
You extract ramdisk.cpio.gz to the /ramdisk folder.
You rename it to ramdisk-recovery.cpio.
Repack image.
(note that when the kernel you use is already a dualrecovery kernel -lightning for example, cwm philz+twrp- and u want it to be multirom twrp, u need to edit init.sh also found in /ramdisk folder somewhere)
BTW thanks for this guide! I was messing with this a few days ago and I couldn't get it to work, thanks to you I now understand why!:thumbup:
I tried to put latest twrp into latest boot.IMG of Thomas lollipop 23/11/14 build and I thought it worked but I press volume up and down to enter the recovery and it does nothing....it doesn't boot,it just freezes with the led lighting.... please help I really want twrp to work with lollipop

Reread what I wrote.
You probably didn't extract ramdisk.cpio.gz, or you putted it into /split_img I think. Cuz I had that too, but if you follow the exact steps it will work!
no I did exactly what you said... I fully understood the instructions,I extracted it , I named it right and I moved it right... well, I will try again tomorrow but I don't think it will boot into it... Thomas boot.img has a cwm recovery ,does this have smthg to do with it?

What version of TWRP did you use? 2.8.1.0 will likely not work, use an older one instead.

Adjusted the description of step 8, should be more clear now what to do.
I've also added a note to point out explicitly that each run of "unpackimg.bat" will overwrite existing data.

thank you sooooo much.... i did it with the second try...the only thing i changed was that i downoaded a previous version of twrp because it wont work with the latest one...thanks a lot.... what about cwm? is it the same proccess?
CWM is included already. But you could split the latest cm boot.img and grab ramdisk-recovery.cpio from ramdisk/sbin to get the most up to date version
is this mean can add TWRP into .FTF files ?
that will be awesome
Can anyone share their twrp included boot.img for the latest thomas release?

Look for a *.cpio or *.cpio.gz file and replace that accordingly. The place doesn't really matter for you, the ROM knows where to find it. CM might expect it respectively at another place. Will take a look later if I can find something...

Won't work like that. Needs a script to be inserted into the ramdisk, @pabx style, plus the recovery folder with ramdisk-recovery.cpio inside.
was thinking why the latest TWRP was not working, then realized that the TWRP is written to be loaded into the FotaKernal.
then it worked with TWRP flashed into FotaKernal.
have pabx_aosp_yuga-509 installed
1. Followed your steps exactly to create a new boot_pabx_aosp_yuga-509.img (with the latest TWRP image "recovery-twrp-2.8.4.1-yuga.img").
2. Flashed recovery-twrp-2.8.4.1-yuga.img into the FotaKernal.
3. Flashed the new boot_pabx_aosp_yuga-509.img
it works

2. Put it on the root of my SD card.
3. In TWRP click install and find the .zip.
Wonderful. Just a question: is this recovery for Idol 3 4.7 (6039) or 5.5 (6045) ?

Convert TWRP Backup into flashable rom zip
I found these instructions that explain how to take a TWRP backup and turn it into a flashable zip file. This would allow someone to create a "factory" rom pre-rooted to be flashed.
For TWRP Backup
Transfer the TWRP backup from Phone to PC.
You’ll see a file named system.ext4.win which is the System partition backup of your device. Rename it to system.ext4.tar (Changing its extension from .win to .tar)
Extract the system.ext4.tar using an archive software like Winrar or 7zip.
If your TWRP backup is not in compression mode, you will directly get the system folder, else you will get a file named system.ext4, which should be renamed again to system.ext4.tar and extract it to get the system folder.
Take the boot.emmc.win file and rename it to boot.img.
Now collect a META-INF folder from any custom ROM which is made for your device. Make sure you get the correct Meta-Inf folder, else the Zip won’t work and might worsen the condition of your device.
Select the META-INF, System folders and the boot.img and right click your mouse and select add to Archive.
In the Archive settings, choose the extension of the compressed file as Zip (Make sure of this part)
Now you can use this Zip file to flash it on your Custom recovery.
we dont have the meta-inf folder...there is one in the update i got, but i dont know if this id the right one.
and we dont have custom rom to get meta-inf from.
also the main thing is, that i cannot unpack the system win file when renamed to .tar i dunno why (i got latest 7-zip app).

What they primarily want is the "update-binary" which is device specific. I don't remember if the update had one....I did take apart an update-supersu.zip and it uses a script as it's update binary...thought about trying to convert that. Theoretically you could take a meta-inf for another device's rom...and use it's meta-inf making sure to replace the update-binary. It also has an installer script that tells it to mount system and data....extract files from the zip and where to put them. I learned a bit when I was trying to make an update.zip to fix my build.prop.
It untar'd fine for me on my linux pc:

i allready build some roms for my older device, so i know what it is about.
For the proper rom zip you have to make the updater script with all the simlinks and metadata ...in the latest update there were no simlinks in the updater script...
without them you can brick your phone.
for example simlinks from 4.4.2 Os from zte V5
Code:
symlink("/data/misc/audio/mbhc.bin", "/system/etc/firmware/wcd9306/wcd9306_mbhc.bin");
symlink("/data/misc/audio/wcd9320_anc.bin", "/system/etc/firmware/wcd9306/wcd9306_anc.bin");
symlink("/persist/WCNSS_qcom_cfg.ini", "/system/etc/firmware/wlan/prima/WCNSS_qcom_cfg.ini");
symlink("/persist/WCNSS_qcom_wlan_nv.bin", "/system/etc/firmware/wlan/prima/WCNSS_qcom_wlan_nv.bin");
symlink("/system/lib/modules/pronto/pronto_wlan.ko", "/system/lib/modules/wlan.ko");
symlink("Roboto-Bold.ttf", "/system/fonts/DroidSans-Bold.ttf");
symlink("Roboto-Regular.ttf", "/system/fonts/DroidSans.ttf");
symlink("libGLESv2.so", "/system/lib/libGLESv3.so");
symlink("mksh", "/system/bin/sh");
this you cannot copy from another device....
Never mind. I installed the second build.
How do I boot into the custom recovery? Is it power up + power button on the Idol 3?

Reboot or power on till you see the alcatel screen pop up....right away hold down up arrow and it should go into recovery.
Thank you so much...been waiting for this....
so now let ROM's start pouring in )))))))
Hmm odd. I had to reflash it. For some reason it didn't take the first time I flashed the second build TWRP to my Idol 3.
What partitions should I backup using TWRP? I'd assume: Boot, System, and Data? Should I include System Image too?

The default of boot, system and data should be fine for personal use however if you have not yet rooted please read here first! http://forum.xda-developers.com/idol-3/help/want-to-able-to-install-ota-updates-t3163745
So Awesome! best looking twrp Ive seen yet xD. Also, works well too. I havent tested backing up data, but I did a successful restore of the system and boot So far so good!

Nexus 6p stuck on Google screen during boot due to replacing build.prop

I Replaced the build.prop on my rooted Google nexus 6p running Android 7.0 with the build.prop file from the pixel to run Google Assistant.The phone is now stuck on the Google logo during boot,PLEASE HELP.
Did you make a backup copy of the file before replacing it, are you rooted, and have TWRP installed?
If so, reboot to recovery, use TWRP Terminal function to copy the backup of the build.prop to the modified one.

I did not make a back up but I am rooted and have Twrp installed.What can i do from here?
If you can boot to bootloader you should be able to replace the file with a standard one.

1. The build.prop contains the settings for a specific build for a specific phone. You can't just replace it from another build, not to mention another phone. Well, I guess, you already know this.
2. You should know exactly which build you were on. Exactly. Then:
* What I would do, is download the factory image from https://developers.google.com/android/nexus/images#angler
o Extract it, extract the image-angler-...zip, and mount the system.img, find the build.prop and adb push it to the phone.
o Reboot
* But you can also ask somebody who has the exact build as you do, and ask for the build.prop. Then push it to the phone.
Either restore from backup or edit the buildprop (if possible) I guess.
You only needed to edit 2 lines in the buildprop though, why replace the whole thing?

First thing's first. Since you didn't just edit your build.prop, but replaced it with another, try setting permissions.
Step 1: Boot to TWRP > Mount > Select "System"
Step 2: Advanced > File Manager
Step 3: Navigate to /system/build.prop
Step 4: Select "chmod" and type "644" (don't include quotation marks)
Reboot and see if it works. If the permissions weren't right and you didn't change them, you'd most likely be in a boot loop. If this doesn't work you can just flash your system.img again. It won't wipe your internal storage, data (installed apps, etc.) If you have custom host files for ad blocking, you may need to apply them again.
If that does not work;
I'm going to assume you were on stock Nougat. Download the factory image (same build you were on before) and unzip the file. You'll end up with a folder with another zip archive in it. Unzip that as well. Inside you'll find a file named "system.img"
Move that system.img file to your ADB/fastboot folder. Shift+Right Click that folder and select "Open command window here"
Hold volume down + power to boot into the bootloader. Connect the phone to the PC and in the command prompt, type "fastboot devices" (no quotes again. ) It should show your devices serial number. If it does, perfect. If not, check your ADB/fastboot installation.
Once you get fastboot to show your serial number all you need to do is type;
Code:
fastboot flash system system.img
That should do it. If you need any more help, just reply back.
Edit: @istperson, AFAIK, you cannot pick out files from a .img file like that. When I right click it on my system and choose mount it tells me the image file is corrupted. Tried downloading again and hashes match. Windows 10. I use 7zip as well, and that can't open it either. Is there another program to use or is something whacky on my end? Wouldn't doubt it. Just took a Win10 update yesterday and it's been acting up on me all day. :/

It's a sparse image, you have to convert it to normal mage with simg2img. Then you can mount it normally.

Flash stock boot, system and vendor img files.
Sent from my Pixel XL using XDA-Developers mobile app
Same thing happened to me at first (though I did not use the build prop from a Pixel). I just dirty flashed my ROM (Octo N) and it then got passed the Google screen and loaded with no problem. I updated my build prop manually in order to get Google Assistant to work, and it's been working great ever since.
