Xperia Pro recovery mode to install CM ROM questions - Android Q&A, Help & Troubleshooting

Hi,
I've Xperia Pro MK16i, with stock 4.0.4 ROM, boot loader unlocked and rooted.
I really want to install recently released CM9-RC1 ROM but have been unsuccessful probably due to CWM recovery.
I was only able to install CWM auto installer which would only boot into recovery if i do it from within booted stock rom, but not manually when i reboot and try to go into recovery mode. i tried all key combinations like volume key down/up when at reboot sony logo flashes bright and led turns blue for a second.
Nevetheless i tried to install CM90RC1 by following official cyanogenmod instructions in which i failed when the guidelines states to fastboot and flash boot.img extracted from CM9-RC1.zip file and then reboot from fastboot. it just stuck there and would not even flash sony logo.
I relocked the bootloader and installed the stock ROM through Sony PC companion repair option.
Now i have again unlocked the bootloader and rooted. but not sure how to proceed now.
I guessed may be i need custom ROM with CWM recovery builtin. i came across this site
http://forum.xda-developers.com/showthread.php?t=1315904&highlight=108
kindly guide me if the link above will help me installing Cyanogenmod ROM and does it come with CWM recovery built in.
Also whats the difference between multiple downloads on the above link like FXP129 and CM9 baseband?
What files do i have to download now, to install Cyanogenmod ROM?
Regards

[Q] Recovery for Custom ROMs

Hey guys,
I recently flashed my Z2 yesterday with the PAC-Man ROM and now want to try flashing other ROMs, but realised that my TWRP has disappeared!
Prior to flashing, I was on stock and used XZDR to flash the ROM, but i didn't flash the "Z2-lockeddualrecovery[VERSION]-BETA.flashable.zip" as I'm on an unlocked BL + custom kernel, which XZDR doesn't support.
I've tried two different methods to getting TWRP installed into my phone, one via fastboot flash recovery and the other via Terminal Emulator, and although the cmd/TE shows the commands and scripts running and all, the recovery does not seem to get installed.
So my question now is how do I get any form of recovery installed into my Z2 (so i can flash a ROM!). I know I can use flashtool to reflash stock firmware and go through the entire procedure again to get recovery and subsequently other ROMs installed, but that doesn't seem to be a sustainable long-term solution!
Thanks in advance guys
Non stock custom roms come with a custom recovery %90 of the time
Press volume up when the orange or purple led turns on when the sony logo shows

[Q] Can anybody help me replace the Cyanogen Recovery with TWRP or CWM?

I've recently flashed CyanogenMod 12 Rom on my Xperia T.
Yesterday I tried to install BRAVIA Engine 3 by flashong a .zip, but I got an error "E:cannot load volume /misc!".
I've read some threads and the comments below and what I understood is that the Cyanogen Recovery can't flash ZIP files...
That's why I want to replace it, but I'm not sure how. I flashed TWRP on Xperia T's stock ROM with adb in fastboot mode and what I want to know is - if I flash it again through fastboot will it work properly and is it safe?
If this is not the way I need some help with replacing it with TWRP, CWM or any good working recovery......
I hope someone will answer this.....
Solved
I've used "Rashr - Flash Tool" and flashed TWRP. It shows you the latest version of TWRP and flashes it.
Working fine on me Xperia T with CM12.

Issues with no working recovery.

Ok long story short i'm confused as to what's up with this device. I just picked it up and started messing with it. Looks like it has mako bootloader unlock and cwm 6x recovery installed. The only roms it can flash is cm12.1 and the factory ATT images correctly. I tried to update to the newer version of CWM or TWRP via fastboot and the flash takes but no recovery is present. Things i've tried =
Full factory reset via LGE970AT-01-V20j-310-410-MAR-08-2013 (this leaves me with no bootloader/fastboot/recovery) It boots but black screen on bootanimation.
tinybin (both options) only the altern will boot but. (have fastboot but no recovery.)
So long story... In stock firmware I can install freegee and unlock via mako but there will be no recovery if I choose TWRP and CWM won't install anything bt CM... I'm attempting to install Blisspop btw.
Any help would be great. Thank you

Unable to access bootloader

Hi,
I have a Sony Xperia Z2 Wifi tablet (SGP511). It currently has the outdated Cyanogenmod 12.1-20160807 (castor_windy). Because it has a lot of software issues, I decided to switch to a more recent ROM (since CM is discontinued). When I tried to access the CWM recovery I had before, I only got the Cyanogen recovery that came with the CM (where it is impossible to flash anything else but CM updates). So I decided to flash the recovery again using bootloader. The flash was done, but caused a startup loop. The sony logo is displayed and the device swiches off and on again, no matter if I leave it or try to access recovery. It seems that it is bricked, but I figured that by continuously pressing the red button besides the SD hole I can still force it to boot into the CM that is installed. So now I can boot into the old CM, and access bootloader by rebooting it via adb. What should I flash to gain back access to recovery?
Nevermind, I fixed it. By accessing the bootloader by ressetting the tablet using adb command I was able to flash the dual recovery from [NUT] . It worked, so I was able to flash the new AICP ROM from it.

I really need help

Hi, today I was more than seven hours on PCr and tried this....unsuccessfully... I'm really desperate
I have:
-Xperia Z2 (D6503)
-Android 6.0.1
-newest firmware 23.5.A.1.291
-UNlocked bootloader
I am trying to install root, twrp recovery and custom ROM ( specifically this ROM ). But i cannot enter to the recovery mode...
Official twrp-3.0.2-0 succesfully flashed in fastboot but when i try command "fastboot reboot recovery" the mobile only load android and turns on normally... the combination hardware buttons also do not work.
The next question is, What is a kernel ? I have successfully installed this kernel .... Could this be the reason why I can't load the recover mode?
Please help me, I don't know what to do anymore :crying: all I want is root and custom rom
EDIT: okay, i successfully root phone and finally i have access to recovery mode (TWRP 3.0.2-0) by THIS TUTORIAL now i need help with installing the custom ROM step-by-step because if I turn something wrong and phone will be bricked again, I guess I'll kill myself xD so What is next step for install custom ROM please ? Can I just download THIS, install the zip in TWRP and that´s all ???

Click to expand...
Click to collapse
before you do this you should backup all your important data
1-wipe data factory reset
2- wipe cache
3- install zip rom
4- download google apps and install it by recovery it should be a zip file
5-repot system and enjoy
the recovery is like twrp or cwm it's not a kernel
there is 2 type of kernel :
1-kernel itself
2-kernel with merged recovery
about the kernel and recovery, there is deference the kernel is very important for system to work it connects between the hardware and the software and every operating system has its own kernel but here in android they sometimes merge kernel with recovery but when you flash-kernel or recovery every one replace each other be careful and know that, don't worry you won't brick something in the near future when you will install custom ROMs you will notice that.
if you need any help you can ask me
