[Q] Root problem on Samsung grand 2

Using Samsung grand 2 (SM G7102), can't root my phone. Tried almost everything. Tried Towelroot, CF auto root and RootGenius but failed. Anyone can assist me about it. How can I root my phone?
I have another problem that is after to press and hold hardware button Volume Up+Manu+power together my phone doesn't go in Recovery mode. Anyone have any idea, how can I solve this problem.
Any advice or suggestion will be highly appreciated.

(For a more successful recovery flash, untick the Auto-reboot option in Odin)
8. If SuperSU is telling you "SuperSU binary needs to be updated", just copy the SuperSU you've downloaded just now to your SD Card or internal memory and flash it via recovery.
9. That's it your done! :victory: Happy rooting!

There is only one way to be able to root your tablet, it requires installing a rootable kernel, which yes, requires a custom recovery. This thread has the kernel you need and this thread has the custom recovery you need. We all had to learn some time or another

ok i dont wanna brick anything so im gonna make sure i do this right.. only part im stuck is :
how do ya boot in recovery on step 2 so you can flash in the zip for the kernel..
1: odin in the philz adv. CWM
2: go into recovery
3: flash in the rootable kernel (ill need steps but im guessing i can find that)
4 edit section) will i need to root it at this point or it already is?
(edit)
just found that i can use CF auto-root for my tablet it was on the philz DL so im guessing i odin again the cf autoroot right after the flasinh of kernel
so im guessing : 4: reboot back in download mode to odin in again the auto-root
then 5: restart my tablet
and 6: rooted tablet
edit: added info i found on philz

No cf-autoroot. Once you've got the kernel installed you need to flash the latest supersu zip

ok so :
1 : odin the philz
2 : go into recovery mode
(oh and how do i do that? i know download is home + dwn vol + power but isnt it power + vol up?)
3 : flash in kernel
4 : reboot again in recovery (then again Q2: )
5 : flash supersu
6 : reboot final regularly to start the tablet
did i get most of it? thanks in advance for the answers to #2/4
i know i ask a lot but i dont want to do something bad for 1st complex root(for me that is)
thanks

Download mode : Power Vol- Home . Hold on all buttons then Vol+ .
Recovery mode : Power Vol+ Home . Hold on all buttons .

i'm now the proud owner of a rooted tablet thanks for all your help everyone

any clearer instructions on this? the custom recovery won't take hold in odin for me...

just adding : the kernel and superSU files gotta be on the sim card of the tablet..
you odin in phil'z recovery(links and info on philz page posted earlyer up,) go read on their page how to do it its simple
in the recovery just after; you just read the instructions. kernel 1st then supersu if you read well all should do well too i didnt have trouble so.. just be carefull and READ dont just skip ...

Thanks for the reply. I wanted to know what is recovery.img used for? In the steps I can't see its mention. And I can't see Dalvik Cache in my recovery menu and in Odin only PDA is not greyed out, bootloader,phone,CSC and UMS are greyed out.

Recovery img is same for install recovry if you want to flash recovery i reecomanded use rashr search on play store and ya u must buaybox just download and install it from play store then open busybox and it install insdie it wait it installer in a minute
Then you can flash and recovery img throuh rashr
In odin uncheck all box only check auto reboot and f,rest time the select pda/ap and select twrp.tar
And hit start
But first you need to go download mode in your mobile (vol down +home+power key for 2to 5 sec then realse the key and press vol up to continue then use odin

Thank you so much rashr and busybox worked

Help Root Samsung S5 5.0 SM-G900H baseband G900HXXU1BOL2 BUILD # LRX21T.G900HXXS1BPD2

Hello, I need help to rooting my phone. I am currently using Samsung Galaxy S5 model number SM-G900H with Android version 5.0, Baseband version G900HXXU1BOL2 , Kernel version 3.10.9-5852541, Build Number LRX21T.G900HXXS1BPD2, and KNOX 2.3.
I've follow many tutorials on how to root my S5 but with no luck... it always get boot stuck after flashing CF-Auto-Root-k3g-k3gxx-smg900h.tar.md5 using ODIN3-v3.10.6. What else could be wrong ?

Some S5s don't like CF AR
Copy SuperSU.zip to your phone/microSD
Flash TWRP with ODIN (Uncheck Auto reboot first in ODIN)
http://forum.xda-developers.com/showthread.php?t=2725939
Once it completes the flash, disconnect the USB, and pull the battery to power off the phone
Replace the battery, and immediately boot into recovery with Volume Up & Home & Power
Flash SuperSU
Reboot (If asked to root again from TWRP after flashing SuperSU, say NO)

I did all the step above but after flashing twrp-k3gxx.tar , remove the battery and entering recovery mode, nothing is change there, it just entering the original recovery mode. Do twrp-k3gxx.tar is the correct version for my SM-G900H ?

What happen if I just flash SuperSU directly via ODIN ?

Did you put the phone in download mode, and did ODIN show a connected COM port at the top?
Did it say successful flash?
Try leaving Auto Reboot checked and do it again, let the phone reboot, and then try booting into recovery
You can't flash SuperSU from ODIN, it's a zip file, not an ODIN flashable .md5 or .tar

Yes I did put the phone in download mode, and ODIN show a connected COM port, i know how to used it and succesfully flashing the twrp-k3gxx.tar, pull the batt out and back in, boot in to recovery mode and nothing is happen... i just entering the stock recovery mode. it is like something overwrites the custom recovery right just before the phone boot up.
I think it is likely that Root image doesn’t seem to worked with the newest Android software update version, or maybe Samsung might also try to released some patches to the Android system that might prevent from customizing ?
I also tried to flasing CF-Auto-Root-k3g-k3gxx-smg900h.zip but it soft-break my phone so i have to flashing back to stock rom (luckyly i have download it before)

Stuck with the same issue. Plenty of Auto Root tutorials are available. Each one specifies that tutorial is exclusive to particular model number. G900HXXUIBOL2 is my build number. Once installed CF Auto Root. When verified via Root Checker, it showed success and got root access !!..But Couldn't enter recovery mode since then..was getting stucked in boot loop when trying to enter recovery mode. Had to restore stock ROM...Really frustrated with Samsung's UI. Wish I could change to Cyanogenmod..Any help would be really appreciated..Thanks in Advance

Which TWRP are you trying to flash?
If it is the latest version, then try an older one.
Alternatively, you can try to root your phone first with CF-Auto-Root and Odin (just Google CF-Auto-Root S4) then use an app to flash the TWRP .img file.
That's how I did it, because I was also unsuccessful in flashing TWRP with Odin.

I was using TWRP 3.0.2...
...tried with version 3.0.1 and I was able to enter in TWRP Recovery mode but after swiping the phone I'm no more able to access recovery mode neither by reflashing TWRP.
Any idea?

The app method worked. Auto root ok. Twrp flashed ok. HTC 6 installed... it's more than one hour in the booting screen (devconnect aosp 6.0 screen)... I don't think it's a normal behaviour... do I have to keep on waiting? Do You have any suggestion?
