[Q] How to make custom ROMs?

I want to know how to develop my own ROM for LG Optimus.

custom roms are available so why not instead of coding do it based of another one like i did

ok, and how can I make my rom based on onther custom rom?
I tryed to unpack system.img with unyaffs, and pack it again with mkfs but my phone stuck in boot loop, or superuser doesn't work...
can somebody please write shor tutorial how to develop roms...

dont repack
instead apply in a zip in recovery

what tool I should use? I tried htc kitchen from xda (it should work on gt540), but I can not even boot my phone...

reflash my rom for example then adb pull whatever you want to edit
then put in zip with an update script and apply in recovery
then create a backup in recovery and that system img and boot img is what you can upload for other people to install
dont give the data img because its personal

I am just that I do this activity.
Could you explain the differences between common, full and slim.
What should I use for a clean installation from scratch.

you have a twrp recovery? Make sure its the latest, version 302-5 is the latest. Im not sure what you want to do, do you want to return to stock or flash a custom ROM?

Hello,
Do you still have the bootloader and recovery images? I have bricked my z00UD phone.

Restore original recovery?

Hi guys..
it may sound funny but.. I decided to install Google camera via this tool https://forum.xda-developers.com/mi-a1/how-to/tool-google-camera-root-magisk-enable-t3747585 and.. i didn't read everything and now my phone is unlocked with TWRP. I want to relock it again, but I need stock recovery. Where can I find it?

I think flashing stock boot.img will do.

Hi laymonage, can youn please tell me where to find stock boot.img? Is it kept in the phone internal memory? Or is it accessible through the Mi flash tool once phone is detected?
Thanks

Sorry for the late reply.
You can copy it from the firmware (fastboot ROM) after it has been extracted.

Couldn't update Installation problem with august update

So this week i hadn't time enough to install the august update since my phone is rooted so i decided to do it now. What i did before trying to download the update :
1.Deleted all magisk modules that i had then rebooted
2.Unistalled magisk using restore image then rebooted
3.Went to sys update downloaded and it says installation failed
What do to? I'm not rooted now and i don't have twrp installed.
PS. don't want to install it via fastboot/miflash

Follow this guide in future. https://github.com/topjohnwu/Magisk/blob/master/docs/tips.md#ota-installation-tips
To fix your problem now, find a stock boot image for your update version you are currently on and flash it.

If you don't want to use Miflash (Why ?) you can boot temporary TWRP and flash .zip here:

It doesn't matter. You'll have to reinstall Magisk (if you want to).

I'm facing same issue and I was following the guide.

Same here, can't install set Ota, even after remove magisk.
Other thing, cell won't show screen to put pin to boot, previous pin of sim so I think encryption is disable!? Any idea?

Error Device, pls help!

After Root and Install TWRP, when I want to wipe the data accidentally I also delete the system, and when I want to reboot the device there is a notification "NO os installed! are you sure wish to reboot?"
What should I do? sorry I'm still new to this.:crying:
thank you in advance

You have twrp. Flash any available custom rom or modify the Updater script in stock rom and flash it via twrp.
Go to this thread for instructions regarding editing the updater script.

After flashing the stock rom flash the decrypt zip too.
