Unofficial EFIDroid for Samsung Galaxy S5 (Qualcomm)

[afaneh92]

EFIDroid is a easy to use, powerful 2ndstage-bootloader based on EDKII(UEFI).
It can be installed one-click with the EFIDroidManager app. You can add/remove/edit multiboot ROM's.

There's no special support needed by ROM's or RecoveryTools(no kexec etc).

EFIDroid official/generic thread here

FAQ

• this is a UEFI port, can we port Windows?
  no, trust me.
• Can I still use fastboot after installing this?
  If you flash to the boot/recovery partitions, UEFI will be overwritten.(dd in android/recovery instead). all other partitions work as usual.
• I FOUND A BUG
  Report it on Github. If there already is an issue for your bug and you don't have anything useful to add, just hit the thumbs-up button. This way I know how many people are affected and can adjust my priority list. I will not keep track of all bugs reported in posts of this thread. If you want a bug to get fixed, report it on github

Installation

• Just download the attached EFIDroidManager App, the EFIDroid Manager app from the Play Store won't work.
• Open the menu (at the top left), and click "Install/Update".
• Click the big orange Install button.

Multibooting

You can use EFIDroid as a multiboot manager. To add a multiboot ROM, do the following:

• Open the EFIDroid Manager app. Press the plus button at the bottom right side of the screen to start adding a multiboot slot.
• Under "Location", there should be a couple paths. Select the one containing "/data/media/0".
• You can give the slot a name/description by using the appropriate fields.
• Press the checkmark at the top right side of the screen to create the multiboot slot.
• Reboot. When EFIDroid comes up, select TWRP, then select the newly created slot.
• Go to the "Wipe > Advanced Wipe" menu. Select "System", then swipe to wipe.
• Install all the zips you want on that slot.
• NOTE: To prevent accidentall data loss when booting in recovery the real /sdcard gets mocked so you are not going to find your .zips as usual under TWRP's /sdcard. To acces the "real" /sdcard go to /multiboot/data/media/0
• Reboot, and when EFIDroid comes up, your new slot should automatically be selected. Press the power button to boot, and enjoy!
• IMPORTANT:your main ROM should boot without changing any configuration on EFIDroid but secondary ROM's are used to fail because of selinux denials. I strongly reccomend you to enable Force SELinux to permissive under EFIDroid options (the Gear icon in the main screen placed at the top right) - Once you kwon your secondary ROM is working you can try to boot without this option disabled - If you end up in a bootloop logcat and dmesg are welcome.

Please add klteaio to the list of supported devices - it's a Snapdragon S5, but it gives me an error that there is "no device value".

Can't believe this is true [emoji1]

Does this use the Qualcomm S5 bootloader vulnerability that is going to be fixed with the Samsung March Security Patch? If so, people may need to revert/prevent updating to avoid problems.

No, you need unlocked bootloader and root only!

My build.prop good sir

This is cm13 build.prop, I meant the stock one, any way if cm13 for klte work for you, EFIDroid works.

 

[Mike20017]

Wow this is some cool stuff. So....Any ROM is compatible? Stock? Aosp? Custom stock based?

This is a cool thing to have because it doesn't forbid you from using several ROMs like multi ROM did.

From the app, press on the slot rom you created for a while then delete it.
Multiboot currently not working on kltevze, dont know about other variants!

Any way I was working on multiboot recovery and got it to work on s5, I will release new build soon.

Thank you bro. Sure I'm going to test your new build :highfive::highfive:

Well... I'm in a sh*ithole at the moment. I updated my ROM (CosmicOS) or maybe was it because of updating Magisk?)) & now I can't anymore boot to it nor can I go to recovery... When I try to boot the ROM (says Android 7.1.1 (internal)) then it's on the "Booting Android 7.1.1..." phase & then?

Error
can't find tagloader for type 'RAW'(-1)

Is there a way to bring back my ROM to life? Only the fastboot & Download mode work...

EDIT: I managed to get TWRP to work, which is a little success... But it now redirects me to it when I try to boot the ROM
EDIT 2: Well, unfortunately, I had to wipe the OS & install it again but this time it booted normally, which makes me happy & doesn't at the same time... If the dev could answer me on all of that, would be gr8
