xperia arc s: cannot boot to custom rom

Hi,
I have an xperia arc s Lt18a. So here what happened:
1. I unlocked bootloader
2. used fastboot to enter CWM and tried to install http://forum.xda-developers.com/showthread.php?t=1539752
3. The aroma installer said "install successfully so I restarted my phone
4. After the SE logo appears for a few seconds, the screen goes blank.
I tried to install with some other custom roms but I get the same problem. Thank you for your help.

Important! Only for unlocked bootloader
- Update Flashtool to latest version
- Flash any stock based 4.0.4 rom or official ftf with Flashtool Skip this step if you are already on a 4.0.4 stock based rom
- Go into recovery and do advanced => wipe dalvik cache and factory reset
- install my rom

Did you follow the instructions correctly?

I did follow the steps. I tried to install the custom roms many times. I flashed the official 4.0.4 ftf and followed step by step. I also flashed DoomKernel before install the custom rom.
So far, I can only flash official firmware but I cannot install custom rom because of the problem described.

Try flashing some other ROM..

in order to install ka21 rom, u need stock kernel with cwm.
1)flash .432(4.0.4) firmware on your phone.(dont worry everything that goes wrong can be corrected once you have a unlocked bootloader)
2) flash the kernel from the below thread.
http://forum.xda-developers.com/showthread.php?t=1680793
3) now, enetr cwm and then install your preferred rom.
u also need to wipe catch partition.

dude u havent installed a kernel...thats y u are having this problem

CWM Disappears after installing any new rom.

CWM is no more there after installing a new rom and new rom won't load. Then i have to flash the stock rom again > root it > install CWM. Again when i install any rom it would install normally but nothing gives a blank screen after reboot and the stock rom is not even there.
The situation is occurring with the following;
Phone: Sony Xperia ARC S (LT18i)
Bootloader: unlocked
Android version 2.3.4 (Build 4.0.2.A.42) -
I have made multiple attempts on installing new roms but nothing works. Every time i reboot after installation im left with a blank screen. Can anyone advise what the problem could be ?
Thanks

Did u flash the kernel for the ROM u flashed ? The ROM will not boot without its kernel.

you must be installing CWM into the system through one touch command prompt program.. as such as soon as the ROM changes and you wipe out data and cache, CWM disappears..try flashing a custom recovery kernel which are available even for stock roms.
Also follow these steps for a custom ROM (eg CM9):
download the ROM, extracted it into a folder, copy the boot.img where you can remember, then copy the original cm9 ZIP - not the extracted folder- into the root of SD..use fastboot mode of flashtools to flash the kernel boot.img which you had copied..its a recovery kernel so CWM should open..wipe out SD data..then cache..and then go into advanced option and clear dalvik..and then proceed to install zip from sd..then gapps.zip if u want..it should install fine..and then reboot.
Press Thanks if you think i was of help to you..:good:

Got it - Yes i was installing CWM within stock rom via market. though i tried to install it through adb/windows but still i guess the problem was all about not installing a custom recovery kernel.
Thanks a lot !

Try fastbooting an opensemc kernel just flashing will not fix. You must fastboot. But Rayman made some fixes in his as people were having problems - http://db.tt/LHNtaSay

First try to flash the CWM or TWRP recovery via fastboot. Then reboot into recovery and try to flash your ROM.

[Q] Need Help Guys!

I recently installed CWM after unlocking my bootloader. But realized after that every ROM requires different recovery (boot.img in the roms). But to install custom ROM you have to flash boot.img and that's what I did with the help of flashtool, but after when I'm trying to boot into recovery it's not even starting! let alone booting into recovery! , I think I bricked my phone guys! How to solve it? Please help!

I tried flashing stock firmware ftf with flashtool, and it worked! Now my phone is back stock 4.1.2.
But still one doubt how did flashing boot.img that came with flashtool soft bricked my phone? did I do something wrong? Also that boot.img was of CM 12 that i was installing at that time. Was that because I flashed boot.img even after having CWM installed prior?

Did you flash the rom from 4.3?
*blink*

Ya, I flashed the CM 12 on 4.3. But when I flashed the kernel i.e. boot.img supplied by the this zip-- ( CM11 unofficial FXP-cm-12-20150203-UNOFFICIAL-z3c_2) zip my phone bricked. I think there was something wrong with the zip, Cos today I flashed new cm-12-20150209-NIGHTLY build and it worked!

Can we change the kernel from Cynogen recovery to CWM ? and can CM 12 work with CWM?

Try fotakernel, use either cwm or twrp, they are permanent (until you flash the original fotakernel)
