Can you edit factory rom/firmware then use rsdlite to flash?

Can you edit factory rom/firmware then use rsdlite to flash?

My main goal would be to swap out the old dialer with black background to the Google dialer with the white background? It's it possible to swap out apk's and then flash that system.img again?

[Tutorial] Edit your Note 4's Boot Splash Screen!

I've tried to find a tutorial for this, but seems like it doesn't exists. So I've learned about S6, Note 5 and even a russian Note 3 Neo tutorials to make it work. So let's start!
What do you need?
-Patience
-A PC with a Photo Editor (Paint.net should do the trick)
-Terminal Emulator with a little of practice
-(Optional) an external keyboard, since you have to execute quite a lot of commands and there's no way to copy paste into a terminal like in CMD.

1)We start by pulling "param.bin" file out:
It's located in /dev/block/mmcblk0p8 so we have to execute these commands:

Code:

---

su
dd if=/dev/block/mmcblk0p8 of=/mnt/sdcard/param.bin bs=4096

---

2) This will extract param.bin to your main sdcard folder, then we have to create a new folder and then untar it, by executing this:

Code:

---

mkdir /sdcard/param
cd /sdcard/param
tar xf /sdcard/param.bin

---

3) If everything went fine, you should see a folder called "param" with all the bootloader's images. We will focus on logo.jpg, but you can change the others like download.jpg and warning.jpg. Extract these files to your PC and edit them, make sure that the images doesn't go up to 400 kb, otherwise they will not show in the device. To achive this you can downgrade the JPEG quality from 100% to 80% or any % you feel confortable to use. Once you finish the editing process, place them inside your main /sdcard folder.

4)Now we have to paste your edited images inside /sdcard/param folder and retar param.bin, we have to execute these commands:

Code:

---

cp -f /sdcard/logo.jpg /sdcard/param/logo.jpg
(OPTIONAL) cp -f /sdcard/warning.jpg /sdcard/param/warning.jpg
(OPTIONAL) cp -f /sdcard/download.jpg /sdcard/param/download.jpg
rm -f /sdcard/param.bin
cd sdcard/param
tar cf - `ls | sort -t.` > /sdcard/param.bin

---

5) Last but not least, we have to place param.bin back again in the system, so:

Code:

---

dd if=/sdcard/param.bin of=/dev/block/mmcblk0p8 bs=4096

---

If everything went fine, reboot and you will see the new logos come up! Make sure to backup param.bin once it gets extracted, in case if something goes wrong. There's no way to brick the device, the major risk is a blackscreen while booting, but the device will boot fine so you can repair it without problem (IF you made a backup, otherwise you will have to reflash the bootloader in ODIN).
I hope you like it! Leave your questions below and I'll try to answer them ASAP. Cheers!

Unable to edit build.prop with rooted phone

Hello everybody,

I'm new to the forum and not that of a newbie concerning Android but since I've updated to Marshmallow on my Nexus 6 I cannot edit the build.prop, even if I'm root.
I already tried a lot of things, since now I used ES File Explorer to edit the file, but now when I want to save it it doesn't work that message appears "Error occurred when trying to save the file. It will not be saved.". So I say ok I'll try using a Build Prop Editor App, it requests root access, I allow it, then fails.
So after many tries I try to completely reinstall the system a second time, thinking maybe there was something I did wrong the first time I installed and rooted, I installed a root checker, it said my phone was correctly rooted, so I try again with ES File Explorer (With root explorer enabled) still the same problem.
Then I find a tutorial on how to get the build.prop via adb shell, which I try, and I have a message saying "Read only File system", so I try to remount but it still the same problem.

Just for the info, the first time I installed Marshmallow and rooted was with a guide on "theandroidsoul" (sory I can't post links since I'm new). And the second time was with the one on ibtimes.
It might not be useful but I tried two different kernels so it might give you some extra info.

Could someone please help me ? I hope I gave you enough information and sorry if I made mistakes, English is not my native language.

Thank you very much for your help.
