i have googled this and tried multiple ways of installing it but i always get a boot loop. Whats going on?
Hey if you just want to get your phone back again, just flash another firmware from the one you used. Should start up just fine.
have done already but i actually want to install cyn mod. I managed to get as far as the main screen buit then immediately reboots. I cant find wifi modules for latest doom kernel either they arent in his thread.
FLASH KERNEL FIRST (from cyanogenMOD or doomkernel for CM7 etc)
Than flash cyanogenMOD
any other way will make your phone bootloop.
I think you have to unlock BL via SE in order to flash CM..
of course you would likely broke your warranty.
this based on my experience (I'm a newbie too in the android's world). this is what I've done :
1. unlock BL via SE (not all carriers allowed this!)..
2. flash .42 fw
3. follow the instructions given on CM thread by fxp.
it's worked for me.
goodluck.
I've had this problem before. Did you wipe the delvic cache, wipe data/factory reset and wipe cache partition in CWM before you flashed the update.zip?
It would seem it was a specific version of cm that was making it bootloop the one from dooms thread 7.2.0 works fine and also the one before the latest stable release also worked fine. I however found a problem with the spacebar on the keyboard when using the phone in landscape so am now going to try arconium and doom kernel its a shame really because cm from what i used of it looked really nice.
Try 7.1.0.1.
I got bootloop too with 7.1.0.2

Aye thats the one i used but ended up having a problem with the spacebar not working in landscape so am on acronium now which is all good but superuser keeps crashing meh always something eh.
at first im also having the same problem,just follow the instruction by FXP : flash bb56,flash fw.42,flash FXP kernel via fastboot,flash update via recovery,wipe dalvik cache,reboot..

I have this exact same problem
I've done everything I was supposed to, I think, and still doesn't work. It boots, shows me the little Android "Welcome!" screen, and before I have time to press anything or begin setting up my device, it reboots into the Cyanogenmod loading screen. I've tried different kernels, different basebands, every time wiping Dalvik cache, etc. and it REFUSES to work. I'm pretty desperate by now because I really wanted to use this ROM so any help is greatly appreciated.
I also followed precisely rashid.fairus' instructions and it still does the exact same thing.

Sometimes you DON'T WIPE ANYTHING AT ALL. Just flash CM and Google.
Works for me on Xperia Acro S.

Only when you upgrade to a later version of the same ROM.

Wipe dalvik and cache when upgrading to later version, wiping data will reset phone to factory settings and you lose all personal data.

Ok if you can access recovery then get out the sd card and put it in another working phone then add few more default ROM-s and try them till it's boot.because maybe problem is kernel and you dont know what kernel is in there.
Or just try to flash an other proper kernel.

First of all, don't post questions in the development section, to answer your question, read the guides and stickys which should have been your first port of call.
no real need to put sd card in another phone.
just boot into cwm, goto mounts and storage. and look for something like mount USB storage.
and voila, your sd card will appear on your pc.
p.s try wiping /system from mounts and storage and flashing rom again

First if you want a custom rom on your phone, you will probably need a custom kernel ass well . Kernel is the bios for your phone and rom the OS. Go to the Rom thread and read there witch kernel is recommended for that rom. After flashing the kernel, go to CWM (Recovery) and flash the custom Rom and finally flash the wifi modules associated to that kernel.
CM based Roms does not work at all with stock kernels, they have their own kernels.
If you want a recommendation (for Kernel, Rom, baseband) look in my signature, you have links included !
Don`t forget the procedure for installing custom Rom (wipe everything : factory default, /system, /data, /dalvik) and only after wiping all install the rom.
Problems (assumed):
1. Locked bootloader
2. Didn't flash kernel
Fixes:
1. Unlock bootloader
2. Flash kernel via flashtool.
I have a problem with the installation of JB. No matter what ROM I install, after boot, when home screen appear, my touch screen does not respond. I've tried a lot of roms and a lot of kernels. I have unlocked BL. In stock rom I have no problems.
What could be causing this? Should I format system before installing rom via recovery or just wipe data, cache and dalvik? When I should flash kernel? Before/after installing rom? I care about CM10. Plz help.
P.S. sorry for my english

I have Neo,and this is how i'm installing it: first wipe everything (data,wipe cache and Dalvik cache),flash the rom,and then flash the kernel.

I've tried to do that way but but not succeed
Certain ROMs require phone-specific patch, make sure you install it!
Other ROMs have different downloads for different phones, make sure to download correct one!
If you install wrong phone ROM, touch dies.
All question threads belong here in Q&A so please post in the correct sections going forward.
Thanks

The problem is caused by the kernal. You MUST have JB kernel to flash any JB ROM. Generally, for each ROM you will find the recommended kernel and the required steps. Do exactly like posted by OP.
As an example, see here: http://forum.xda-developers.com/showthread.php?t=1979829
You can make an idea on the steps to follow.

Ok, so now I have installed Xperia T rom (7.0.A.3.195 v6.0 for ARC/ARC-S). Should I flash V77 baseband, then flash kernel from CM10 FXP150 pack via fastboot, make a wipe (data, cache, dalvik) then install ROM via Recovery, and then install GAPPS and it should work? This is what i'm gonna do, so if I'm wrong please tell me.
EDIT:
(edited in case someone had same problem)
I found the solution:
I had to flash BB 72 and libs, then flash ROM+GAPPS and libs once again, then everything works awesome. (edited in case someone had same problem)

I'd got a touch screen problem.
Could you please tell me that how can i flash 'libs once again' So, I can try on my Arc.
Thank you very much.
Hello! I am new to the Xda community, and I have a Xperia S. I went throw a lot of Rom threads and read all, even video tutorial and because of that I got confused. Can anyone spare some time (aprox. 10 mins) to answer me some questions, by chatting or here. Please do not make a fool out of me like some other guys around here.
1. if i go into bootloop after flashing CM10, can i restart the phone and go into CWM without flashing again boot.img, and flash the rom again?
2. if i go into bootloop after flashing CM10, do i have to flash the stock rom using flashtool?
3. tell me a simple way to get out of bootloop.
4. flashing the CM10 on my SXS with built number *.2.55 will work?
If I have made anymistakes by posting this here, i would like someone to take it down. Thank you for your time.

I dont have an Xperia yet, but from reading and experience from other phone ...
1) did you wipe data, cache and dalvik cache? if not, try to do it and check again for bootloops. If not possible then reflash the firmware and try to wipe these things directly after flashing the firmware.
2) if you wiped, try to restart with flashing the firmware again and wiping everything.
3) if nothing working reflash stock, boot stock once to see if it is working without bootloops and then restart from scratch.
4) if also not working .... is it the correct firmware? did you forget something?
There are good instructions for the firmwares, if you do everything as explained, you shouldnt get bootloops. But ... no howto is perfekt.
Its mostly trying as much as possible, till you have the correct way to flash a firmware. Bootloop isnt that bad ...
If you have a way which works for you, keep the steps for later flashing and tell the community what you had to do differently or if you missunderstood some points, even then tell it, because that can make these instructions better.

I would say that it doesnt matter which firmware is on the phone, as long as you unlock the bootloader and the fastboot or flashtool is working.
The custom firmwares use the same methods but might have added recovery for easier flashing later.
You should even be able to downgrade to older firmware with unlocked bootloader and flashing the ftf file.
Its only important to wipe the data, cache and dalvik cache that the firmware is working.
thank you very much but still to solve all of my problems:
You said "1) did you wipe data, cache and dalvik cache? if not, try to do it and check again for bootloops. If not possible then reflash the firmware and try to wipe these things directly after flashing the firmware."
what do you mean by that? which firmware to reflash CM10? how by restarting the phone? and will i be able to go into CWM without the boot.img?

With different phone and different firmware i had some issues with recovery, specially if i didnt wipe directly after flashing the new firmware without reboot and without reboot into recovery ...
I hope i dont mix anything up. CWM is the recovery (?)
The recovery function is part of the kernel image which is exactly the boot.img.
You can see at the freexperia project page howto install CM10, i cant post links at the moment.
3rd point is flashing the CM kernel (boot.img)
4th point is booting into recovery
From that recovery you can flash the custom rom as described in point 5.
Point 6 is wiping the device, which is neccessary for first custom rom or if you change version (eg. CM9 to CM10) or if you change to a different ROM.
Most bootloops happen if you forget to wipe the device. I am not sure, but most important is dalvik cache, if that one is wiped the next boot takes longer, as it will be rebuilt during boot.
If you get into a bootloop after flashing kernel and custom rom, go into recovery and wipe the device, try rebooting.
If still in bootloop, try to reflash the custom ROM as in point 5 (starting at 4th point) and wipe device after flashing
If it didnt help, try reflashing the kernel and ROM, starting at point 3 and include the wiping the device.
If that didnt help, try to go back to full stock (kernel and rom) and repeat.
But check if you got the correkt ROM for your device.
Play a bit around with the steps, you can even reflash the kernel and leave the rom. I had once a bad situation with bootloops, but they are easy to fix. More important is the part with the kernel, i think there you can brick your device.
But when you follow the instructions you shouldnt have too many problems, just dont jump over a step at the first flashing. But as allways sayd, every custom rom, every kernel flashing can harm your device and you're responsible on your own.
But if you get into problems, write down what you did and you will get help here.
Edit:
"if not possible then reflash the firmware ..." There i had once a problem with a different device. I forgot to wipe after flashing a new version and got into a bootloop. In recovery i couldnt wipe the device fully, something got bugged, but reflashing helped. Reflashed wiped and i could reboot into system. As it was longer time ago i dont remember what exaclty happend, but i think the problem was about forgetting to wipe the device.
Wow Thank you soo much, you lost allot of time explaining this to me, I really appreciate it i understood everything I owe you really
ooh and what do you mean by wipping - all: factory reset, cache and dalvik or just cache?

didnt take too much time
in case of first custom rom, changing custom rom version (e.g. CM9 -> CM10) or changing to a different custom rom: all: factory reset, cache and dalvik
in case of updating (e.g. CM10->CM10): dalvik should be enough, maybe cache and dalvik.
If something not working, do a complete wipe.
As I understand from what I read, you flashed cm10 and are now stuck at boot, did you fastboot the kernel? On my xperia s I always need to fastboot the kernel after flashing a ROM, especially when changing from an ICS to a jb ROM.

No, he has no bootloops, from what i understood he is scared to get into bootloops and doesnt know what to do if it happens.
Hmm, kernel flashing after upgrading from ICS to JB? or all the time?
By kernel flashing you mean the boot.img flashing with fastboot, and its the same file as flashed before?
I've only ever fastboot'd my first kernel, advanced stock kernel. Any others have always been in recovery and never had any issues

It seems that you got the wrong Kernel. I'm not sure, of course.
But I had that issue some time ago, and a fix it flashing the right kernel that I found on xda forum. Ohh, dont forget to do the proper wipes.
I hope u solve this as soon as possible.
For some good info on recovering a phone read through the recovery thread in my signature.
Even if you don't have any issues now, you can see what others have done wrong & right.

am doing all the steps mentioned, and am still on locked boot loader.
thats your problem you cant have custom roms on locked bootloaders.
when you install other custom roms you should follow those steps
factory reset
cache partition wipe
wipe davlik cache (cwm>advanced)
(i also format system but its optional)
install rom zip
reboot... i do this and i have never stuck on sony's logo
