Greetings.

[Q]; Is it safe ? Yes it is.
[Q]: Will it work for my device ? Try it and U will find out ...
[Q]:Unroot possible ? Sure use option in SuperSu apk or better backup recovery/whole stock rom.

Since many users proposed to me to create a new thread for fullroot of Galaxy Core 2 phones ( some models ), I decided to do so.

It's made for stock recovery for Galaxy Core 2 and for latest update of it.
Stock recovery for G355HN and any other custom recovery.
GC2 stock recovery phones have not fully working SELinux recovery support and the CF instalation of SuperSu won't work. Read : it also work in permissive mode.

Custom Recoveries :
TWRP :
Original developed by @Y300-0100 http://forum.xda-developers.com/gala...55h-m-t2998094
modded by @Dhruvit Pokharna http://forum.xda-developers.com/gala...-2-sm-t3013103
CWM :
Original developed by @cleverior.ipul http://forum.xda-developers.com/gala...alaxy-t2990852

If you have working CWM / TWRP/ Mobile odin ( recovery with full SELinux support) you could use update script from ChainFire to obtain fullroot and install SuperSu or use latest update script by me.

What needed :
Galaxy Core 2 phone with android 4.4.2 able to goto stock/custom recovery, no other preroot attempts needed like preinstalled busybox,preinstalled init.d, because all this need the preroot access and installation.

This update zip is made specialy for G355HN devices. Tested on Galaxy Core 2 SM-G355HN on 4.4.2 Android on both stock roms available,
but it should work on some devices Galaxy Core 2 with stock/custom recovery.

How to :

Code:
1. Shut down your phone until last vibe ... it's OFF !
2. Enter stock recovery - hold 3 buttons (Menu + Power + Vol up)
3. After init select "apply update from external storage", press power button to enter
4. Select the previous downloaded zip . The file you have previously copied to extSdCard - and press power button ...
5. The script will run ...
6. If all goes ok, your phone should be rooted.
7. After boot android will upgrade - Superuser apk ask for update su binary.
8. No internet connection is neccessary for this step ... Select continue,normal way and wait for the success.
9. Hit thanks if it worked 4 you
Thanks for Superuser and binary goes to Chainfire

Powered by SuperSu !

And finaly :
About OTA updates and system status, CF Auto root options :

After rooting the device your system status will become custom ( Device status : Custum ).
You can check it in Odin mode ( download mode ), check current BIN and System status .

You can reset binary flash counter with Triangle Away but you cannot fool OTA update program so easy.

When you are rooted you can't check for updates OTA. There was a lot of chat about whether you had to defrost various apps etc. to fool the update feature. Using Wanam Exposed, under "Security Hacks" you get the option to change (fake) "System status" from "Custom" setting to "Official", and thus allowing you to check OTA using Samsungs update feature. Much easier than having to check Sammobile every day. Hope it helps someone.
... but the OTA removes root, so you have to root the updated version again. The almost same is with GravityBox.


CF auto root by Chainfire is still not available for GC2. Still waiting for it.

Any other posts regarding those 3 questions will be deleted by moderators.

Feel free to post any other questions and infos regarding rooting your devices and root feedbacks/errors.

You can always update your phone via odin,kies or any other updates, only OTA updates are not possible - for now, accept if you flash stock and update it throught OTA.

Nope, I have the Samsung Galaxy Core II SM-G355HN. It's completely new, bought through my mobile carrier. I updated the mobile to the latest version, 4.4.2.

Then I just intruduced a microSD card, transferred the required zip, and followed the easy steps. I've been using my GC2 for 2 days and I'm so happy I found this thread. I removed all the bloatware and all the apps I didn't want, then I installed Nova launcher and now this phone is so fast. I recommend you to install Nova launcher cause, in spite of being way faster and quite more responsiveness than anything else I've seen, the Touchwiz version that comes with this phone is awful, it's different from any other Samsung interface I've ever seen, I hate it. Besides, Nova is ultra customizable, I love it so much that I bought the PRO version. With the stock Touchwiz of the GC2, you can't even create a shortcut to "Manage Applications".

Cheers!
