[REQUEST] Build system.img - General Questions and Answers

Hello,
I have an ASUS K01A tablet with a blank system partition and unusable recovery. I can flash img files to their respective partitions just fine (boot.img, droidboot.img) in fastboot, but 'system' in the stock firmware zip is a directory instead of a flashable image. Of course, this (and other reasons) means I can't just flash the stock firmware in fastboot, nor flash over the entire 'system' directory.
I need a system.img to recover my tablet from softbrick, but I can't for the life of me compile one. I've exhausted every method and tool I could find in both Windows and Ubuntu.
I beseech the community; if there is anyone reading this who could build such a file for me, I would be eternally grateful. I believe I only need the system.img to recover the tablet.
The stock firmware is at the ASUS website. Here is the download link: UL-K01A-WW-12.8.1.41-user.zip.
Thanks in advance!

Why not extract the system folder of the ZIP linked to, then pack it into a ZIP what you then convert to IMG using an online-convertor that does the job?

"Why not" indeed; that sounds like it would more than suffice. Can you please recommend one?

Anyone? I have been unable to find this "online-converter" despite days of searching; still at square one.

Only as example ( found via Google search !!! )

Thank you, but I've tried this one and all the others on Google, and none will handle the filesize (~650 MB). It must be purpose-made for Android .img files it seems, which I've been unable to find.

I built it finally using IMGBurn to create the raw img and Sparse Converter to convert it to sparse img fragments.
But now the tab has formatting error, and with -u option, flashing errors (all partitions and imgs now). Ah, well.
Thank you to everyone! Hopefully someone else reading this will have better luck than me.

Download the attached file from the link at the bottom of this post and unzip it somewhere on your PC. It is a temporary recovery launcher. We'll come back to it in a moment. Based on your original post I'm assuming you already have your stock firmware downloaded as well as ADB and Fastboot setup. From your stock firmware unpack the following files: fastboot.img, splashscreen.img, and boot.img and place them in your ADB/Fastboot folder. Copy the stock firmware to your sd card (in its original, unzipped form...the way it was when you first downloaded it). Put the tablet in fastboot mode. Run the following fastboot commands from a command prompt.
- fastboot flash fastboot fastboot.img
- fastboot flash boot boot.img
- fastboot flash splashscreen splashscreen.img
Reboot back to fastboot mode. Go to wherever you unzipped the temp recovery that you downloaded earlier. Double click on launcher.bat. Type accept in the window, then type T2 and your device should boot into CWM recovery. Now choose install zip>install from se card>and choose the stock firmware.zip that you previously copied to your sd card then let it do its thing. Once its finished go back to the first page of the CWM recovery that you're in and select reboot system now>no>no. You should be golden now. Post back if you have any issues.

what's the difference between an NBH file and a rom in a ZIP file?

from what i understand... you can apply an image file with an NBH extension through fastboot... and you can also apply an image file with a ZIP extension through a flashed recovery mode.
what's the difference between these two kinds of files and two methods of flashing?
also... the instructions that i followed on the cyanogenmod website had me perform these steps.... 1) flash NBH in fastboot, 2) flash recovery using app installer, 3) flash cyanogenmod through recovery mode. my question is... why was the first step (flash NBH in fastboot) necessary? why couldn't i have just gone straight to flashing the recovery mode and then flashing cyanogenmod using recovery mode?
thanks for the help everybody!
anybody? somebody must know the answer to this.
i think nbh file contains all of the rom function such as spl, radio, system,image while zip file contains onyl apps, boot image and system folder

So let's get started
First of all download & install 'android image studio'
1: open it and click on repack/unpack
2: select the port ROMs boot or recovery img.
3: we get two folders
a.) Split_img --->> contains kernal zimage.
b.) Ramdisk----> contains init.rc recovery. Fstab etc..
4: to delete any file long press on it and click delete
5: to import any file click on import button in right panel & select the file
6: after making desired changes. Repack the img using repack button
7: a file will be created with the name image-new.img

I need more help, trying to open a .IMG boot file for Samsung s5, it gives the "No Image Supplied" error
Screenshot
Using AIS. Trying to port custom recovery but first thing I've tried is to just unpack and repack stock recovery. When repacking output of AIS is new IMG and new ramdisk. New IMG is smaller than original but from what I've read this should be okay. Flashed new IMG and attempted reboot recovery and all I got was black screen. Flashed stock recovery and it booted recovery fine. Not sure what I'm doing wrong. I used AIS to open the new image it created and then kept doing file/folder comparisons on the output. I narrowed down the difference being recovery.img-ramdisk.cpio. But when I unpack with cpio the contents of the archive are the same. Additionally, I repacked the contents with cpio but it still comes up as not matching the original recovery.img-ramdisk.cpio. My device can and does make replacement recovery images using applypatch with bonus files and boot img. Any help greatly appreciated!

Need boot.img FRD-L09 B404

Hello everyone.
I unlocked a bootloader in my freshly bought Honor 8 last week and I the first thing I did was to flash a root package (obviously). I'm used to SuperSU, so tha's what I flashed. Then I found out about Magisk. I want to try it, but I need to flash stock boot.img in order to install it. My build number is FRD-L09C432B404 (EMUI 5.0, Android 7.0). Could anyone upload corresponding boot img? I'd be thankful.
Do it yourself! ^^

Hello!
You can do it yourself, just follow these steps:
1) Download your firmware (update.zip) from hicloud url: update.zip
2) Extract zip
3) Download "Huawei Update Extractor 0.9.9.5" (zip file): HuaweiUpdateExtractor_0.9.9.5.zip
4) Extract zip
5) Open "HuaweiUpdateExtractor.exe" extracted from previous step
6) Click on the 2 dots button and navigate to the file to add the "UPDATE.APP" file ( extracted from step 2) ), it will show you all the files like boot.img , recovery.img , recovery2.img , system.img , etc.
7) Select "BOOT.img" and right-click > "Extract Selected". Choose this destination folder: Where fastboot/adb are installed.
8) Use fastboot command to flash "BOOT.img":
Code:
fastboot flash boot BOOT.img
Hope it helps you!
I'd rather not download 1.3GB of firmware for the sake of one small boot.img which can't be bigger than 50MBs, not to mention additional software I'll use probably never again, so I'd be thankful if someone sent already extracted boot

[Q] Installing System raw image with flashable .zip

I'm trying to make a flashable zip for TWRP to install a Lenovo Z6 Pro stock ROM. I create the .zip file with Boot, System and Vendor (I'd add the rest of the firmware later). Boot and Vendor are installed but system.img is not installed. I know that I could use .dat files but I'm specially interested on using the image files.
I took as template another ROM which uses .IMG files too with the function 'package_extract_file'. I just replaced the .IMG files making sure that the names are exactly the same, and also I'm sure that my system.img is raw. When I try to install the flashable zip from recovery it prompts the uiprint "Patching system unconditionally" but nothing is installed and skips directly to patch the vendor partitions which is successfully patched.
Any help or clue will be much appreciated. Thanks in advance.

Download the stock recovery and any TWRP from the internet for your device. Downlaod carliv image kitchen and extract your stock recovery. Copy recovery.img-kernel and “recovery.img-kernel_offset”to any location in your pc. Now take the TWRP for your phone that you download but it's not WORKING. Extract it in the same way using carliv image kitchen. Form this extracted TWRP of your device delete recovery.img-kernel and “recovery.img-kernel_offset” and replace it with the file you copied from your stock recovery in the first step. Then repack this image and flash it. BTW is your bootloader unlocked?

Yes, my bootloader is unlocked (if you mean to ask if i have checked OEM/USB debugging in developer mode), I unlocked it first time i tried to run TWRP.
By "repack this image and FLASH IT", flash it using Odin, right?
My current TWRP is unaccessible

[TUTORIAL] How To Extract Files From a TAR.MD5 Stock ROM (SPH-D710)
I've received a TON of PM's and emails asking how to do this and I've decided to do a write-up for everyone. Now to start off, this does not automatically make you a Super Duper Developer, this does not show you how to make your own TAR ROMs...
forum.xda-developers.com
Open carliv.bat batch file.
Copy your device’s stock ROM’s recovery.img and paste it in the “recovery-resources” named folder that is located inside the unzipped folder.
In the Carliv Image Kitchen window, type in R and press enter. Next, type 1 and hit enter again.
Type 1 to unpack the image file that you downloaded earlier.
If you get a message, “Your image is unpacked in recovery folder”, you have successfully unpacked the image file.
Now open the recovery folder in the Carliv unzipped folder. Look around for a folder named “ramdisk” and other files.
Create a new folder somewhere and name it “stock” (you can name it anything you want). Copy and paste all the contents from the “recovery” folder (ramdisk folder and all 10 other files).
Next, delete the recovery.img file that was left behind on the “recovery-resources” folder before.
Also, delete all the contents in “recovery” folder.
Copy and paste the custom recovery image file, the TWRP that you want to port into the “recovery-resources” folder.
You will need to repeat the same steps as before.
never delete the custom recovery image in the “recovery-resources” folder.
Copy the “recovery.img-kernel” and “recovery.img-kernel_offset” from the stock folder and paste it to the TWRP which you extracted in recovery folder in carliv image kitchen . Overwrite it to replace existing files with the same name.
In the Carliv Image Kitchen window, type 2 and hit the enter key.
A message notifying that the image file was repacked will appear. You can view it on the output folder named “output”. This is the brand new TWRP ported image file.
Copy the newly made image file from the “output” folder and paste it to a new folder. Rename it as you want with any name of your choice. Hope it helps. If you are still stuck I'll do it for you

thx,thx,thx for the support!. I have done the carliv protocol but in the end the new compiled twrp failed in Odon. Maybe the new image converting to ,tar is the culprit? after that i tried to do the method in the video but twarp was 3 seconds visible and then back in bootloop!. i shall DL the magisk 20.3 edition. maybe that makes the difference'I bought this A7 last monday after a HUawei, that has no posibilities whatsoever for twrp or root, but in this Samsung I totally surprised that it, untill now, is so umbeatable, albeit unlocked!

Convert TWRP .img to .tar (for ODIN)[Easy]
Sometimes the latest version of TWRP is in ".img", so some people use an older version instead, which is in .tar, so they can flash it with ODIN. The thing is that the ".tar" version is just the ".img" compressed XD, so I'm going to show you how...
forum.xda-developers.com
i had done this with z7 myself already, but to no avail, but: i began, in a moment of despair, with Odon to try all the .tars i had collected sofar , to flash and when i flashed PBRP (it was not the first time) it worked!!!. after a week the gizmo do have a recovery, that is not stock! Little new prob: By rebooting system he bootloops (for a change!) in bootloader mode.
