Before you flash twrp with odin unchecked autoreboot, when done, reinsert the battery and try to boot in twrp by pressing up+home+power.
Or did you try this :https://forum.xda-developers.com/ga...uide-rooting-g800f-marshmallow-6-0-1-t3558915

Hi, I have the same setup and I've tried both methods to get root with no success. I had TWRP but the quickroot took it back out. Error shows binarys not installed so was wondering if unlocking the bootloader might fix the issue. Any suggestions? Also SuperSU has been updated according to Play store.
Thanks in advance.

Hello,
You must first install stock recovery in order to manually update through Updater > Local update, and yes update.app must be in the dload folder on the SD card. (connect your device to your PC, install adb, reboot it to bootloader using 'adb reboot bootloader', put 'recovery.img' into the same folder as adb, execute 'fastboot flash recovery recovery.img', then do 'fastboot reboot', once your device is fully booted go to the Updater app, and do a local update.)

That is exactly what you need - adb reboot bootloader (<- it's one word!) gets the phone into fastboot mode (same as flashify). From here you can flash the recovery. On the PC, run fastboot flash recovery <path-to-stock-recovery>. This will get you the stock recovery on the phone. Now you can use the 3 button method to flash the stock ROM.

You must get it into fastboot mode. If the phone restarts and does not boot into the OS, then it's a huge problem. You may try to restore the phone with HiSuite, but my bet is that you'd better get it to a service - you probably flashed the wrong bootloader.
You might have luck with the recovery though - hold down VOLUME UP and POWER when turning the device on. This might get you ADB, so you might boot into fastboot mode.

You are right i have to get it to service its not working at all cant even find in fastboot neither in recovery .. this goes so expensive
Press power, volume-down and connect device to PC simultaneously. You will get into fastboot mode. Flash boot image and recovery image that was exactly from your firmware version.

try flashing TWRP 2.8.5 the official version and you should be able to boot to TWRP Recover.

Ok, so the ROM by pabx, This rom does not have in built arrangement for TWRP, you will have to compile it on your own.
You will find the steps here http://forum.xda-developers.com/xperia-z/general/turorial-add-twrp-to-boot-img-t2951658
and then flash TWRP to Fotakernel first and then flash boot.img

could I flash a philz recovery?
I can't find a .zip and can't do "fastboot recovery.img "the philz.img
thanks
I have not tried Philz, so i cannot give you an answer.
you may want to head over to this link http://forum.xda-developers.com/xperia-z/general/z-xzdualrecovery-qa-t2477769
Had the same problem.
TWRP Recovery wasn`t available after I flashed yuga.
Used "TWRP Manager" (only with root) which worked for me even when the app said that the installation failed.After rebooting I was able to enter TWRP again.
SO I installed This and I now have TWRP 2.8.
0! My rom won't boot any more, but who cares I can now install CM!..............I hope
have you tries the hack that oliver has on his thread http://forum.xda-developers.com/showpost.php?p=57718351&postcount=2
flash Olivers TWRP to FotaKernal and then from cm recovery flash the hack, reboot and enter recovery and check
I have not personally check but give it a try if you like.

Unlocking bootloader and installing Custom recovery [Sprout4] [Marshmallow 6.0]

So i have successfully installed a custom recovery on my phone running Marshmallow and also unlocked the bootloader!
Its quite simple actually!
I am not responsible for any damage you make to your phone!
Steps-
1. Download the zip file from the link and extract it.
2. Install both the drivers and then proceed!(The drivers are universal and work for Windows 98,xp,vista,7,8,8.1,10 but in 8,8.1,10 you might need to turn off the digital signature verification-Make good use of google)
3.After installing the drivers , connect your phone in switched on and remember to turn on usb debugging in the dev options!
4. Open the unlock_bootloader_... and run the .bat file and follow the on screen steps( All the data will be formatted so make a backup beforehand)
5.After doing this you will void your warranty so make sure you know what you are doing!
6. Open the one click installer folder and replace the recovery.img with any recovery that you want.
7. Now again connect your phone in switched on mode and usb debugging on and run the .bat file of recovery installer.. and follow the on screen steps!
8.As soon as the the recovery installation is over do not let teh phone reboot just press the vol up button as the installation process stops and then go to recovery!
9.Boom!! Now you have a phone with unlocked bootloader and a custom recovery installed on marshmallow!!
10.Flash custom Kernels,Boot Animations, Logos and root your phone running marshmallow and brag!

Recovery Kernel?
Hi bro just a quick question did you use the MM kernel in the custom recovery?
On our None AOSP standard Mediatek devices the rom does a Kernel check to ensure both the boot and recovery Kernels are of the same version eg KK boot = KK Recovery LP boot = LP Recovery so I just wondered if the MM Kernel still works in the Philz recovery or are you still using a kernel from a older version of android eg KK or LP.
Hope that makes sense to you :laugh:
How to open the unlock_bootloader ??? There is no such option
how about rooting? what method did you use?

Can't open superuser?

Hey guys I tried to root my HTC One Mini 2 using Kingoroot which says it succeeded, however the superuser kingo installed does not open, in fact it just pops up an error saying: "com.kingo..." has stopped working. I tried to restart the device and re root it but it still pops up the same error message when attempting to open superuser, anyone know what is the problem here?

Then instead of using Kingroot, try flashing the SuperSU zip through a custom recovery.
I did not find the need to use SuperSU when rooting the One Mini 2, just unlocked the bootloader, flashed custom recovery and then flashed the ROM.
Works super fine..

You have TWRP installed? Use Method 2 of the unbrick guide. Now you want to wipe every partition then adb push your rom (not sideload) and manually flash it. Make sure you are on the latest Bluspark twrp.
