Confused and need help

Hello xda members,
I own a Xperia Arc, was running android 2.3.4 and decided it was time for a new rom for the phone, i carried out a couple of steps but in the end i got stuck, and i can't get into cwm recovery to restore or install a new rom, and i cant even root the phone, here are the steps that i carried out in order to try and install a new rom( Sorry they are long):
1: rooted my Arc using a program called "Eroot v1.2", I enabled usb debug mode and connected, pressed the button and it rooted it, I managed to see the superuser app installed and i also downloaded an app called "root checker" which verified that my Arc was rooted successfully.
2: I downloaded a program called "recoverx" to install cwm recovery on my Arc and once again it was done successfully, i switched the phone off and back on while holding the volume up button and i got into cwm recovery.
3: I went into cwm and made a rom backup
4: I downloaded the new rom (Xperia Ultimate HD Rom) onto my sd card and went into cwm recovery and deleted everything such as wiping the
data, and a factory reset, and i deleted the delvik cache and the bettery stats
5: I went to the install from sd card, and installed the new rom, and at the end i unchecked the "Reboot" button, and it took me back to cwm recovery and pressed on reboot into cwm
So after this point everything seems fine and to me im sure iv carried out all the correct steps, but....
6: after this point the phone rebooted, and after the sony logo, it gave a black screen and was stuck at that screen no matter what, at that point, i could not get into cwm recovery anymore.
7: After reading and searching the internet I managed to educate myself that i was supposed to flash something called a kernel, so i downloaded a tool called sonyericssson xperia flash tool, and downloaded a kernel called lt15i_4.1.b.587_kernel.ftf and flashed it, turned the phone on only to find that my Arc was stuck in a boot loop, it was restarting after the sony logo immediatly.
8: I then downloaded another kernel called lt15i_4.1.b.431_kernel only.ftf and flashed it which cured my boot loop and the phone booted successfully, however my main problem now is that I can no longer root my Arc, and I can no longer get into cwm recovery no matter what.
Iv also read about using the fastboot method to install kernels but when i do it, it says failed as the phone is not rooted, so now i have no way at all of rooting or installing the cwm recovery.
I currently have a locked boot loader as well.
So if anyone can please tell me how i can sort this problem out it would be amazing, or if you could just tell me what i did wrong or where i went wrong and how i can sort it out, I really want to install cwm recovery and just restore my old rom back, or even install a totally new rom.

You can't flash kernels
Try SEUS or PC Companion to repair your phone
Then root it, install CWM and restore your backup
For UHD you need ICS kernel so update your arc to official ICS, then root it, install CWM and flash UHD

Odin flash the stock kernel which you had before installing the International kernel.
Good luck!

If the above doesn't work use the efs bootloop fix and flash it via twrp

[Q] CWM works, but boot loop on multiple ROMs, can't revert to stock

Please help me unbrick my phone! (panicking slightly)
A few days ago I received a new XP1C, and I immediately (without ever booting it into stock) unlocked it, flashed boot.img from the newest CWM nightly, and proceeded to install cyanogen's newest nightly.
BOOT LOOP.
I've tried:
1) other ROMs (both from Cyanogenmod, and other developers). All result in boot loops.
2) using flashtool to try to return it to stock. It connects to the phone, but fails during the process.
3) connecting with ADB - device is not showing up.
when I do a wipe data/factory reset I get some errors:
Error Mounting /data!
Skipping format
...
E: unknown volume for path [/sd-ext]
...
Error mounting /sdcard/.android_secure!
Skipping format...
I would be most grateful if anyone had any ideas of things for me to try. I have been all over the forums and am totally out of ideas... :crying:

Did you backup TA partition?
Cause from what i understand you need to restore those keys before reverting to stock rom.

I did not back up or change anything when I got the new phone. I just took it out of the box, plugged it in to the usb on my laptop, and did the Sony unlock process.

Flash a stock firmware in flashtool (e.g. http://forum.xda-developers.com/showthread.php?t=2768044 )

Flash stock rom using flashtool and boot into os first, then proceed to fastboot and custom rom.. You have not reboot after unlocking BL, and flashed kernel using fastboot.. Thats why u r getting this error..

Problem with recovery in lg f240k

Hello guys, I have a problem with my phone. I need to install a custom recovery in my LG F240k but when I install one recovery my phone brick. I tried to install twrp and philz recovery but when I install and I restart my phone, my phone only start in recovery mode or show me the error "error boot certification verification". I think the error is because I don't have the phone with bootloader open and also I need help to unlock the bootloader. I use the app "freegee" but i don't have the model e980 and this program show me a error. I have LG F240K model, android 4.4.2 and software version "F240K20H". I don't use android 5.1 because the recoverys and tutorials working in android 4.4 and when I install custom recovery I make the wipes. Also I need help with the vibration of the phone, I can delete complety the vibration of my phone, editing the build.pro maybe?
Someone help me? Thank you for the answers :fingers-crossed:

You're on KitKat, FreeGee isn't working with KitKat aboot and never will. Use GPRO recovery apk from forums (if you can't find it in forums, tell me, I'll upload it somewhere, but really try finding it on forums first) to flash compatible recovery, then flash from freegee or simply flash twrp with flashify. Or even better, flash stock jellybean and use freegee on it.
About vibration issue, I don't understand. You want to completely disable it? Just go in notification settings and uncheck vibrations and haptic feedback everywhere you see it.
