PLease Help me! on what to download and what to do. im still new so i cannot understand if someone post link and not posting instruction please help me guys! Please!!!

First, you may want to reboot and just try again.
Press power + volume up at the same time for some seconds, when the phone reboots try to access TWRP again by pressing volume down some times.
Edit: sorry, volume up is philz recovery, you need to press volume down on reboot for TWRP. My mistake, I corrected the post.

Download a ROM for your S3 that you know will work (Stock Samsung or CM10 or something stable) from the S3 Android Development section (Should be a zip file).
Copy it to your SD Card and reboot into ClockworkMod Recovery.
Then backup everything by selecting "Backup And Restore"> "Backup".
Then select Format Dalvik and Format Cache, then go into Mounts and Storage and format your /System.
After this return to the main menu and install the ROM you downloaded earlier.

[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

It would help if you said where you got the boot.img
And ignore the sony logo, focus on the led, when it lights up, press vol+ repeatedly (dont know how many times, i just keep doing it until its in recovery lol
If you installed doomkernel v5, try swapping vol+ for vol- or camera button, vol- = twrp (think thats right) and camera = philz

Problem with CM 12.1

I bought a phone from China - JiaYu G4s. It came with Android 4.2.2, so I decided to install kitkat. Kitkat worked well, but I knew it is not enough. I found Cyanogenmod 12.1 for that phone. I installed it, but forgot to wipe /data and /cache and it was crashing. I tried to access recovery, but I didn't know how (Clockworkmod recovery carliv 4.4, I had a custom ROM, where when I long pressed power buttom, there was a option to reboot in recovery). My preloader never worked, so I couldn't access files from computer. So I rebooted my phone and in setting press factory reset. My phone rebooted to recovery and a sign "Processing" appeared. But It crashed and I had to reboot my phone. Now I'm stuck in boot animation, I can't go recovery, I can't access my phone from computer. I can't do anything (I think so). Can someone help me?
Power off your device then try these buttons one by one to enter recovery
1. Power button + Volume up + volume down(this one should work)
2.Power button + Volume Down
3.Power button + Volume Up
Try volume down + power button to enter the fastboot mode and flash your recovery or rom again
