AT&T Samsung Galaxy S5 DeBloating

Commodore 64 · Apr 15, 2014

Hello to all the fans of less programs/apps forced on the user.

To begin I'm listing what I have disabled/turned off from the stock rom, and I'm getting a better battery life and see less junk.

Note: I'm not using any of the apps/services listed above, and I have not run into any problems. If you are going to use them then don't disable them.

Battery life has increased enough to be noticed, but not dramatically.

Next Project: Make an Odin flashable DeBloated stock ROM in both rooted and unrooted versions.

I got a full Stock ROM download from Samsung Kies to start Debloating and adding Root using Android Kitchen.
This file contains four files:

AP_G900AUCU1ANCE_964333_REV00_user_low_ship_MULTI_CERT.tar.md5
CP_G900AUCU1ANCE_964333_REV00_user_low_ship_MULTI_CERT.tar.md5
CSC_ATT_G900AUCU1ANCE_964333_REV00_user_low_ship_MULTI_CERT.tar.md5
BL_G900AUCU1ANCE_964333_REV00_user_low_ship_MULTI_CERT.tar.md5

Accomplished:
System folder is located and the apps listed above deleted from "AP_G900AUCU1ANCE_964333_REV00_user_low_ship_MULTI_CERT.tar.md5"

Also ran this through the Kitchen and got it rooted, signed, zipaligned, ... (Choosing the lazy option for now) and got my output .Zip

Stuck on:
1- the Android kitchen .Zip file is flashable using a custom recovery mod. e.g. CWM or it's PhilZ version, which isn't currently available for this phone.
I don't have previous experience that these .Zip files can be flashed through Odin. So I assume it won't work.

2- Cannot put the System folder I Debloated back together to get accepted and read by Odin.

I'm sharing my Android Kitchen's Cygwin window screenshot of the file information.

so what needs to happen now is the content inside that zip file need to get converted to "system.img.ext4" file, then I will put that file back into the tar ball "AP_G900AUCU1ANCE_.... .tar.md5" and load it up in the PDA section of Odin.

So that is where i'm stuck; in re-packing all those files back into "system.img.ext4" file. There is a delicate way to do this, also discussed in parts somewhere on the XDA forums. One has to know the final partition size to include it in the command used to pack those in to a "system.img.ext4" file.

That is awesome. I can't wait to see this finished. Seems you found a way to root it. Are you going to make it so that a "noob" like me can do it?

even if you get it back in the tar your not going to flash it in odin, the AT&T bootloader is locked odin will not flash a file once you have rebuilt it because it does not contain the samsung signatures. i have already got a fully built flashable ROM for the AT&T just waiting for root and BL unlock.

your on the right path, so dont get discouraged but it just isnt that simple.

P.S. Before you even ask, yes i have tried multiple iterations of building the system.img.ext4 file and signing it.
P.P.S if you really want the best experience from building a rom build a linux box (either linuxmint or ubuntu) the kitchen is a great tool
but running under cygwin in windows there are many limitations including not being able to create a system.img.ext4 file or generate the correct md5sum.

Thanks cstayton for giving me a glimpse of what i'm dealing with here. From your comments a I searched further and found

Standing by for SM-G900A root release. I'm taking down my DropBox Dl link above since it is no use any more.

No root = No dev on the ATT or VZW versions of the S5 this is because of the locked BL. Likely that there won't be a BL unlock or bypass like Loki. Eventually a root exploit will be found just a matter of time, but no one knows how long that will be. There likely down the road after root will be safestrap which will allow custom TW roms based on the stock TW kernel. What likely won't happen is AOSP.

CF-Root does not work and never will as long as the bootloader is locked due to how it obtains root (modified stock recovery to push root). /System cannot be modified to root the ATT/VZW S5, this has already been cofirmed by Chainfire. An exploit on Kit Kat has to be found. Sadly anyone who got the ATT S5 expecting great Dev support right out the gate picked the wrong variant.

Has anyone tried safestrape?

I don't believe that the S5 is on his supported device list as of yet, and even then Safestrap requires root.

Duh Thats true. So first step is ROOT!

A friend of mine mentioned that the note 3 has a locked BL and Knox but is still able to be rooted. I am wondering if the root for the note 3 would work on the s5. Has it been considered or tried? I would try it but I do not have the knowledge necessary to undo it if something goes wrong. It seems like something that could really mess up the device if you don't know what your doing.

Don't try it @TheSheibs. Just wait for root to be announced. It'll be a big deal if and when it does.

Srixun · Apr 17, 2014

@TheSheibs Try it! if it works youll be the man!
Just be aware of the issues.

I have the rom cooked and ready and it was ready to go in odin 3.07. Well the thing is if I'm willing to part with the one year warranty since it will advance the knox counter and at the end of the day that shouldn't matter anyways because even if a root solution/exploit is released, flashing it by odin will still advance the counter ...

Once root is achieved (hopefully soon-ish) will we see prior AT&T devs flocking to the device for things such as SafeStrap and TriangleAway. I assume once we have root we will have a way to trip the knox shortly after. Root is key.

Simer03 · Apr 17, 2014

My s5 is coming in a matter of hours! I'm looking forward to root but I don't mind staying stock for a while as long as I can disable apps! The part I'll have to get used to is no more "Greenify" app but oh well

So what at&t and verizon did was not only lock the phone's bootloaders but encrypt them. The encryption part is problematic for now.
If we can't flash with odin then we can't load custom recoveries like cwm/twrp then this phones becomes less attractive for developers. I have made a rooted version of stock ready with android kitchen but currently I don't have a way to load it on my device to test it.

I tried and Odin crashed, knox counter did not advance.

Well your right, Odin will not flash any custom rom with locked bootloader, once you touch the stock img.ext4 you break the samsung signatures, nothing you can do will flash that file.

If it was as simple as re-creating the system.img.ext4 and flashing with Odin we wouldn't have to worry about locked BL.
