[TUTO][A3] 5.0.2 Xposed without Custom recovery or Knox Tripping - Galaxy A3, A5, A7, A8, A9 General

Hi,
what started as an Idea seems to be working now. For once i wanted a phone that has warranty for more than two weeks (or at least a chance for warranty).
DISCLAIMER:
Do all of this at your own risk. Even though we will not be flashing a custom recovery, technically the warranty is lost the moment you root your phone.
None of the Tools is actually written by me, i just tinkered a bit and came up with this tutorial.
1. You will need
- Galaxy A3 (mine was an A300FU but i guess every one that can be rooted without flashing should do) on Lollipop (5.0.2).
- Minimal ADB or some other software that brings debugging drivers and adb.
- KingRoot 4.60+
- SuperSu-ME (from play Store or an older version is also fine) or any other way to go from the Kinguser Root Management to SuperSU
- Deodexed apks matching you phone model
- Flashfire Beta
- Xposed Installer, I used 3.0alpha4
- Xposed bridge for Samsung lollipop I used xposed-v75-sdk21-arm-arter97-snapdragon_requestConcurrentGC
2. If something goes wrong:
- Odin and a stock LOLLIPOP ROM for your device!
This is Important: Since we dont have a custom recovery, whenever something goes wrong the only rescue is going back to a stock rom and thereby wiping. If everything works in the first go there will be no wipe.
3. Rooting
First we need to root. Thanks to KingRoot thats very easy and just a matter of waiting. Install KingRoot (has to be 4.60+ for Lollipop), Click try to Root, wait for it, done. Know we need to get rid of the KingRoot stuff again and install SuperSU (FlashFire does not support KingUser but SuperSU) thats what we need SuperSU-ME for. There Will be some Left overs since KingRoot converts itself to a system app, you can remove this with Titanium Backup or a ROM Toolbox of you choice.
4. Deodexing
Next step is gonna be Deodexing. This one is a little Tricky without a Custom Recovery. Flashing the Deodex using FlashFire will leave you stuck at the Boot Logo.
Unpack the Flashable Deodex zip. you#ll find a META-INF and a system folder. Copy the system folder (or rename it, doesnt matter) to your SDcard or the phone memory using USB. At this point you can also copy the two Xposed files (zip+apk). Next we need USB Debugging. Install the minimal ADB, browse to the install location and start "adb devices" once (this will start the daemon). Now take your phone, browse to settings / phone info and tap the build number like 10 times (this gives you developers options) now go to settings / developers options and enable USB debugging.
Connect you phone via USB. This hould bring up a dialog granting your PC permission to connect. Click Yes.
Connect to the phone and request root using
Code:
adb shell
su
Now turn on the phones screen there should be a root request, allow it.
Next is the following commands, assuming the location of the extracted system folder is /storage/extSdCard/deodex_system
Code:
mount -o rw,remount /system
rm -Rf /system/app
rm -Rf /system/priv-app
rm -Rf /system/framework
cp -R /storage/extSdCard/deodex_system/* /system
chown -R root:root /system/app
chown -R root:root /system/priv-app
chown -R root:root /system/framework
chmod -R 755 /system/app
chmod -R 755 /system/priv-app
chmod -R 755 /system/framework
rm -Rf /data/dalvik-cache/*
reboot
This will replace all system apks with the deodexed ones, sets the right owner and permissions, clears the dalvik cache and reboots. Booting is gonna take a while and then you're enjoying you're rooted, deodexed stock ROM without flashing anything so far. So now about installing Xposed.
Don't be to slow with thus step. Deleting the three folders will make the phone go crazy and at some point reboot, you should be done by then.
Edit: I did this on a second device now, for some reason the remount did not work. In this case try disabling SElinux (http://forum.xda-developers.com/devdb/project/dl/?id=12178) and then remount.
5. Xposed
Install the XposedInstaller apk file like any other app, no need to start it yet. Next install FlashFire and launch it (granting root access) now select the Option "OTA or ZIP" in Flashfire and select the flashable Xposed zip you downloaded earlier. No further settings needed just hit Flash! The next reboot is again gonna take a while, but after that you can launch the Xposed Installer and start Installing Modules. We're done.
Whenever you do a factory reset (from the recovery), You need to root again using Kingroot, replace it with SuperSU and install Xposed again.
Once more, I did not develop any of the tools mentioned, all credits to their respective authors.
Cheers,
prometh
Edit: I did not try too many modules yet but Wanam for lollipop works just fine and that useless S Whatever bar is a thing of the past

Hi.
I already have a rooted Galaxy A3 (A300FU) and I have TWRP as my recovery so my warranty is already gone and I'm not too worried about that. However I have had no success at trying to deodex my rom to be able to install xposed.
Would it be possible to just flash the deodexed and the xposed zip from TWRP? And with regards to the deodexed zip would it matter if I flash it over the top of my current rom when I'm using a carrier rom rather than the BTU unlocked rom?

I think this would be a question for the deodex thread I linked but heres my 5 cents: The procedure in your case should be Flashing Deodex (eventually also gapps_replacement from that thread if you get Google Apps FCs) flashing Xposed, booting, installing the xposed installer. The Deodexed zip is meant to be flashed on top of your system. What I described is basically doing manually what the deodex zip file would do (deleting copying...). Since you have twrp already, I guess a system backup wouldn't hurt.

Many thanks for the help. I'll make a nandroid backup of system first just in case and then give it a go.
Thanks again.

Impossible with my SG A3 A300FU
Hello, I already have the root and TWRP installed, but if I try to type the command line with ADB it doesn't work and if I flash the zip, it doesn't work too. Any Idee ? With the first or the second method boot loop with the samsung logo !!

If you try the adb commands whats the exact error? Permission Problems? Anyway the Command line should do nothing else than flashing the zip file (I dont know what the zip file wipes after flashing but I assume its dalvik and cache).

Great work prometh696 !!! I managed to get xposed on my A5 with knox 0x0 !!!
Some other steps I followed to get it for my A500FU; first I extracted my own system folders system/app/, system/framework/ & system/priv-app/ with root explorer to my ext SD card and then copied it to my computer.
On the computer I batch deodexed those folders with joeldroid's batch deodexer:
http://forum.xda-developers.com/and.../script-app-joeldroid-lollipop-batch-t2980857
Had some issues there as not every Java version seems to deliver the deodexed folders without errors; more details in that topic.
Then I followed your adb commands and installed xposed, and as you said, knox didn't change and is still 0x0 !!!
Thanks again !!!

The command lines are for copying the deodexed apks (so not in a zip). The zip is for xposed and is flashed by flashfire.
But as he already got TWRP (and thus knox 0x1) I see no use for him to use your method anyway

When I type the first command line after this one "rm -Rf /system/priv-app" or this one "rm -Rf /system/framework" I don't know when exactly my phone reboot and bootloop on samsung logo (dynamic one) ???

My mobile restart before end of commands line
Hi,
your solution seems really good but my mobile (A300FU) is retarting before I typed all commands line.
Do you know a solution ?
Maybe cause I've no ExtSDcard and use the internal card ?
Thank you for your help !!
Regards
Virtua
update : I tried with trwp and made the necessary but the mobile does not boot.
This phone is a mess
It's the first time I can't do what I want with a phone. All posts seems to be a hoax. ;( ;(

Whenever you do a factory reset (from the recovery), You need to root again using Kingroot, replace it with SuperSU and install Xposed again.

This is actually incorrect unless root is systemless.
Root remains in system, and so does xposed. A factory reset does not touch the system partition.
You lose root after a reset because you need to reinstall superuser. If you make it a system app you won't lose root even after a reset.
The same with xposed just reinstall the apk.
