Flash this kernel by @ShadowElite with fastboot: http://forum.xda-developers.com/xperia-z2/development/kernel-elitekernel-v1-t3427540
Turn on your phone, when the yellow led comes up press volume up, Then flash this zip, Recroot v4 (TWRP RECOVERY): https://drive.google.com/open?id=0B6aEcBP7FwsWNmJDbXRkNDlCS1k
After you have flashed Recroot, flash this (SuperSU 2.76 SYSTEM MODE): https://drive.google.com/open?id=0B6aEcBP7FwsWa0c5TmFURjhVUTQ
Good luck!
Also, check out my customised stock rom based on 23.5.A.1.291: http://forum.xda-developers.com/xperia-z2/general/stock-root-xposed-twrp-ub-lb-d6503-mm-t3433442

[Q] How to enter recovery mode in Xperia P

I have a stock Jelly Bean 4.1.2 installed on my xperia P handset. I wanted to install the custom rom CM 11 on my xperia. So I first rooted my handset using Doomlord Easy rooting toolkit. Then I copy pasted the custom Roms zip file in the internal storage. Then in order to install the custom rom I need to boot into the recovery mode of xperia P.
So I first tried using Quick Boot but it goes on rebooting to the regular jelly bean OS and doesn't enter the recovery mode.
Could anyone guide me which step I actually missed for installing the custom rom. If a perfect guide is provided I would be very grateful.
press power button + vol up button for 5 seconds... it will vibrate 1 time.. it will reboot.now keep pressing vol down key or power button ((because in some kernel key is different.)) key until it displays a menu in blue fonts.it's clockworkmod recovery.:good:

I tried doing the steps as guided by you. On pressing the volume up key and the power button it vibrates 1 time then I kept on pressing the power button. So then the phone booted in safe mode again and again and then when I stopped pressing the power button the phone booted normally again in Jelly Bean. Is there any problem with unlocking the bootloader. I have received a key for unlocking the bootloader on my GMail account when I requested it on the sony's website.
did u tried with volume down key to enter recovery..? u said that u wanna install cyanogenmod ..so u need a custom kernel which can be found in same zip file of rom named 'boot.img'.& & a custom kernel needs unlocked bootloader. if u have to unlock your bootloader ..u have to search ..it's very easy and can be found on this forum,too(( if not pm me i'll send detailed steps.)).& yes,u are gonna need that key which you received to unlock bootloader .
u can always use ( fast boot ) to flash cm11
it`s better and best ......
any ways u could inter recovery mood by pressing volm+ 2 time`s after the phone vibration ....when sony log show...
its always work
If you installed CMW, to enter it I push about 10 or 15 times, while the phone is turning on, until it loads the cmw

If u wanna help at least write it the right way...
For CWM, turn on phone, when it first shows the Sony logo start pressing various times (Volume - ) key (don't push one time and keep the finger on the key!!) until it enters cwm recovery.

For me it works only with Volume '+'
In CM11 zip, u have the boot.img... flash it using fastboot (doesn't work on Windows 8 or 8.1), then u'll have the CM11 kernel... turn on the phone and when it is starting, it'll vibrate when showing sony logo, just tap the power button when vibrates and will enter in CWM, then just follow the tutorial in CM11 topic.
so what's the right way to reboot in recovery mode? I've this kernel http://forum.xda-developers.com/xperia-u/p-development/rom-cyanogenmod-11-0-t2626639

I got same problem to reboot in CWM mode. Following all recommendations in this thread. Did not work.
However when coming back to one of the Xperia Phone instructions to reboot in CWM, I tried again to follow those instructions given by following links :
Sony Xperia P CyanogenMod 11 Project page Thread on xda-developers https://sites.google.com/site/androdevlinux/xperia-p/xperia-p-roms/cm11-download/
Here are extracts which I strictly followed :
First time flashing CyanogenMod 11.0 your device, or coming from another ROM? You need to be on Unlocked bootloader
Fastboot kernel(boot.img) from the rom zip
Press power button when Device vibrates at boot splash/logo to enter TWRP recovery
Format data and cache
Flash the Zip
Reboot​
The "Press power button when Device vibrates at boot splash/logo to enter TWRP recovery" is really the trick to enter CWM mode ....
i installed a custom rom, but due to some reason it hasnt installed properly and not letting me access settings. and moreover i am not able to install CWM recovery as vol - button way is not wrking.
Wht shd I do?? please help

Root and recovery are two different things.
To have recovery you need to install one, for locked bootloader I assume.

If you're on nemesis kernel, press power button several time, if you're using CWM for locked bootloader, press volume down key for several time until u saw the recovery!

There is no recovery built-in Sony stock kernel, as I said you will have to install one, either recovery for unlocked bootloader, or flash a custom kernel that has one built-in.

G925FXXU3COI9 Root

Is there a possible way to root the g925fxxu3coi9 5.11 S6 Edge? I've heard some guys tried to and got stuck at the bootscreen. And if it is possible, could somebody please reffer me to a guide on how to do it safely? Thank you.
Hey rsnail_valy! I guess you are looking for this thread. I haven't rooted my one yet though TWRP Recovery 2.8.7.1 and Root for G925F Android 5.1.1 (unofficial)
Yeah I saw that thread but it's not really explicit at all, I can't really understand what I have to do reading what it says there, maybe someone could explain...
Hi, Yesterday i root my 925F through this method Just do it bro download all three files. TWRP, Kernel and Super User..
Copy Kernel and Super User file to your phone..
then power off and go in to recovery(Holding Vol Down + Home + Power) ...Flash TWRP through ODIN(Uncheck Auto Reboot in options) After Flashing Holding Vol down and Power to turn off mobile.
After that Go to recovery by Holding Vol up+ Home + Power .
You now in recovery Now Flash Kernel and Super User then you are Ready to go

Umm ... I'm in the same issue as the OP. How do you flash Kernel and SuperUser with TWRP ? You just flash them with ODIN while you are in the Recovery tab, or how ? Please explain, because I tried once to root my COI9 and I got stucked in the bootloop and I just don't want to repeat this again.
After I flash TWRP with Odin then I proceed to flashing Kernel and SuperSU (which I previously copied on my phone) with TWRP from the recovery menu shown on my phone's screen? And also, after this rooting method am I going to be able to use fingerprint scanner on the lock screen? I heard some guys lost this feature of the phone after rooting, is this true?

Hi, thanks for the thread. I've been able to enter TWRP. But, after I reboot into the system. I'm having a bootloop, then I can still get into Odin mode and repeat this step. But, when flashing TWRP. Either I'm too quick to turn off my phone. Downloading is at 99%. What can I do to fix this? Then whether to install TWRP when it will reboot to the system? Thanks.

Can you have access to the fastboot (blue light VOL+UP + Plug) ? If you can flash TWRP custom recovery and flash the stock rom via TWRP
No, can't boot into fastboot. After pressing power+volume up/down it shows green led and charging icon.

to enter in fastboot don't touch the "Power" juste hold volume up and plug your sony
Tried that too but not working. No blue light
Solved.....by reinstalling drivers and some magic. Don't know what.
Closing the thread.
