Well. There are few simple ways.
First is can you enter the recovery?
If not, then just use the command "fastboot flash boot boot.img". As boot.img select some kernel with custom recovery (doesn't matter if lollipop, kitkat etc.). After that just flash some rom and optionally a proper kernel for it.
However if your bootloader is locked you may just flash an ftf with flashtool.

If you don't have unlocked bootloader, then fastboot is useless for you.
As they guide users over your post in a locked bootloader just flash stock firmware for your model device with Flashtool.

Then there's probably something wrong with your adb drivers.

did you read good and do this?
HOWTO
to flash cm7 rom you have to take 3 steps (after unpacking the 7z archive)
step 1 - copy update.zip to sdcard
step 2 - flash new kernel (always use the kernel provided in CM7 / it is incompatible with stock ROM)
ON PC - run fastboot flash boot boot.img (an black window will open and will stay open untill kernel is flashed)
ON PHONE - put phone in fastboot mode (power off then press lower right key and plug usb cable) and phone LED will light BLUE
step 3 - when phone is booting (first 5 seconds) press volume down key several times to enter recovery and choose apply update from sdcard
WARNING - if you used another rom (stock or custom) you have to wipe data or device will not boot
DOWNLOAD
look in my signature
please don't mirror (we want to have download conunt)
Hi
When you were installing CM7 on clockworkmod did you remeber to wipe everything? before you install the rom, on the first screen of clockworkmod you see wipe data and wipe cache. Wipe them both then go to advanced and wipe dalvic cache and battery stats, after that install CM7. So what should you do:
1. turn of phone
2. connect to pc on fastboot and flash kernel with built in recovery (Command: fastboot flash boot boot.img)
3. now disconnect phone and go to cwm and wipe everything like i said
4. install cm7
if works hit thanks ^^
btw. sony ericsson logo, seems like you didnt even flash kernel?
Since u are saying u seeing sony ericsson logo seems u didnt flash kernel properly, use flashtool in xperia neo dev section makes things way easier.
Good luck bro hope this helps !

just flash that kernel via fastboot. don't use apps to flash kernels
fastboot flash boot nameOfKernel.img
I think you forgot to flash the custom kernel,cos if you flashed the CM kernel it should not show Sony Ericsson boot logo,it should show CM boot logo
update
I flashed .42 firmware again using flashtool and the device is now working
Now i realized that the problem was that i didn't properly unlock the bootloader...what i want now is a way to unlock it..bcz everytime i try it gives me this error
(bootloader) Unlock phone requested
FAILED (remote: oem unlock failed!)
finished. total time: 0.003s
I searched the forum and tried this thread

but it didn't give any kind of solution, Anybody can help ?

[Q] How to enter recovery?

Hello, I recently rooted my Sony Xperia Z2 because I wanted to install a custom ROM, but this is where it gets tricky....
so i got root access and the bootloader unlock allowed is on "yes" so that's good right?..
anyway I've been trying to get into recovery mode but it just doesn't work at all, i also tried installing CWM and TWRP and even Philz but it was a failure because there is no way to get into recovery mode so, is there a way or something I could do to enter recovery mode to install a Lollipop ROM ?
ps: sorry if this thread is already made, i didn't find anything useful
Update: I have shut off my device, held the volume up connected to my pc and the LED turned BLUE! HOWEVER, there is nothing on the screen is just BLACK.

This is fastboot mode, not recovery.
Have you actually unlocked you bootloader? It needs to be unlocked before you flash lollipop. If it is unlocked, just download a kernel and flash it via fastboot.

Never seen that before. What are you typing in? Copy what you type and the response into a post.
Nowhere not confirmed that the bootloader is unlocked, but that can be unlocked. You wrote this - " /so i got root access and the bootloader unlock allowed is on "yes/". If you have locked bootloader, then don't try with fastboot flash boot boot.img. Just downloaded version of Dual recovery Installer for Pc.

Stuck on cyanogenmod Recovery with bootloader locked (oem locked)

Hello guys. I unlocked the bootloader via adb (fastboot oem unlock) and flashed the cyanogenmod Recovery and after that i flashed Cyanogemod 13 (the official nightly).
Then I relocked the bootloader (fastboot oem lock)
Until here everything is fine. The problem is: After that I use my phone with CM13 normally, but I wanted to go back to stock, so I turn on developer options then i turned on the OEM unlocking thing, and usb debuging. And when i entered in fastboot mode to unlock the bootloader again i wrote via adb fastboot oem unlock the phone rebbot and now i am stucked on cyanogenmode recovery with the bootloader locked.
Another thing: if i flash the cyanogen 13 again the phone will allways reboot to recovery.

Never lock bootloader unless you are on stock ROM (oos). Now you need to unlock bootloader.For that you need stock ROM and stock recovery. Are you able to boot to any ROM,cm 13?
@ateresabelo maybe you have to flash stock Rom. Hopefully then it will allow you to unlock bootloader. Best of luck mate.

Thanks for the reply.
I can flash CM 13 ROM with cyanogenmod Recovery, but when the flash finish, when I reboot, the phone boot into recovery mode, and not boot into the ROM. So it flash the ROM without errors but boot into the Recovery again.

Flash stock ROM. Download it from oneplus website. And use TWRP recovery instead. Cwm is kind of obsolete and i m not sure if it works perfectly.

The thing is the recovery that i have is not CWM is the cyanogenmod Recovery (with oem locked). I only can boot into CM 13 ROM if i go to the fastboot mode and then type: fastboot continue. If I do that I can use the phone with CM 13.
But when I reboot my phone from the ROM it come back to the cyanogen Recovery and not boot to the CM 13 ROM. And I have to repeat the process: Go to fastboot and type fastboot continue in order to boot on my ROM.
So is any way to unlock the bootloader, like fastboot oem unlock (with the cyanogenmod Recovery instaled) in order to flash the OPX stock recovery or the TWRP recovery?

Ok, do one thing. Download flashify app and flash stock oxygen recovery through it. Remember this is an app. After that when you go to recovery, you should have stock oxygen recover. Flash oxygen os after that from stock recover. Try and let me know.

Just another question: for that task (flash the OPX stock recovery do I need root access?) I am asking this because I do not have the SUperSu installed. So maybe I need to use the cyanogenmod Recovery to flash the SuperSU and hope it works and then use flashify, right?

Thanks a lot. So, I am ready to do that. I have the stock Recovery for the OPX from OnePlus website and now I am ready to flash it via Flashify.
Just the last question, If I flash the stock recovery with the bootloader locked, does it will hardbrick or softbrick my phone? I just ask that, not because I dont trust you, because I trust, but because I read that is not a good ideia flash recoverys or roms with the bootloader locked.
Thanks again in advance, mate.

Just look at ROM section and decide, Its raining ROMs for oneplus x. ROMs( like zephyr, orion, ownROM etc) compiled with UBER toolchain are smoother, so you may wanna try them to get awed.

I installed the flyme rom now no recovery, fastboot and flashmode

Good Mornig
:crying: I installed the latest Flyme rom on my Togari but now i can´t boot in to my recovery.
But if I boot into the Rom I don´t have Problems.
I only cant Boot to the Recovery and also i don´t can boot into fastboot or flashmode.
Sry for my English but im from Germany
If i try to boot into flashmode only the led is going for 1 sec. yellow and my phone turns off.
Also if i try to boot into fastboot, my Phone vibrates 3 times and then it turns off.
If I try to boot with the NDR Utils App into the Revovery, my Phone only makes a Bootloop.
I used this Rom :FlymeOS_4.5.1.1R C6833/02
and here is the thread :http://forum.xda-developers.com/xperia-z-ultra/development/rom-flymeos4-5-1-1r-c6833-02-t3165834
ADB is installed. The Phone is also Rooted. for Recovery i Used NDR Utils.
Thanks for Help
NDR utilities....I guess you are using NUTS XZU dual recovery well mate it clearly said that whenever you flash a rom using xz dual recovery....you will lose your recovery...there was a flashasble zip which needed to be flashed after flashing rom which won't erase your recovery
Now regarding your fastboot or flashmode.... Are the latest and proper drivers install....don't care about the led flashing does the PC detect the device In flashmode? If yes just reflash stock back using androxyede flashtool and make sure you install the new bootloader next time via Emma which has a separate recovery partition in it.....regards if you need any help feel free to PM
You can flash dual recovery or download twrp manager, follow instructions and you'll be granted twrp recovery

Don't use install img option on twrp it may not work always
Instead of that you can flash recovery using fastboot with "fastboot flash recovery (the name of recovery).img) command

Note that the Z2, like most other Sony devices does not have a proper bootable recovery. As such you have to install a kernel that includes a recovery with it. For a time I will try to continue to supply updated stock kernels repacked with TWRP in them. If you are running one of my kernels or have a custom ROM like OmniROM installed, you can install TWRP in the FOTAKernel partition to stay on the latest version of TWRP.

To install a stock kernel, boot the device into fastboot mode and then from your computer: fastboot flash boot path/to/filename.img

However is it true? With latest updates there was bootloader update which brings (or at least should as Sony said) /recovery partition (or more gives access to it, coz partitions was probably always there).
However how it exactly works? I always thought that onee flashed update with newest bootloader will leave new bootloader and this partition forever. But I got Z2 with .291, downgraded it to 4.4.2 for Root and TA backup and than tried to flash recovery to recovery partition, but got error: FAILED (data transfer failure (Unknown error)).
Does it mean that only on latest update(s) there is possibility to use this partition?
Never tried it on my ZU before. I just started form latest 5.1.1.
EDIT: OK, so what i assumed was right - on 6.0.1 I was able to flash the recovery to it's partition.
Now the problem is with booting into it. How? With Power + Vol- it still stright to boots to OS...
EDIT2: adb reboot recovery boots to different bootloader screen (Power+Vol- gives SONY screen and adb gives SONY + XPERIA screen.
However it still boots strght to Android...
Any idea what I'm doing wrong? I have 23.5.A.1.291 + unlocked bootloader + TWRP 3.0.2-0 (official) flashed with fastboot flash recovery img.
I'm 100% sure that SONY screen (w/o XPERIA) is the right one as I have identical one on my ZU when booting into bootloader-recovery mode. But why here it don't boot TWRP, but OS?
HELPPPP
Pleaseeeee tell me how did you flash twrp 3.0? I have tried almost everything it now seems impossible for me... Pleaseee helpp me T_T ... Thankk youuu
