[Q] Xperia Arc won't boot after CWM crash

I am new at all this stuff but i think I'm starting to somehow get a hang of it. I rooted my phone this week running .587 by downgrading the kernel etc, you know. Today I wanted to try another rom so I followed this guide: http://forum.xda-developers.com/showthread.php?t=1955248 To install Xperia Ultimate HD on my phone with a locked bootloader.
However during step 8 CWM shut down and started to boot. But it doesn't start and I'm unable to get back into CWM My computer won't recognise the phone so I can't flash the kernel or do a complete reset using SUS. What do I do? is it save:able?

Been doing flashtool ftf recoveries whenever this occured. Do not power on arc s with it stuck. let flashtool self boot to flash mode and you will be back in buisness again.

if you could tell me what to do a bit more precise I'd really love you! like a small guide

I assumed you have flashtool since you mention about kernel downgrade. if no get it installed
the step actually same as flashing the kernel with phone power off.

1. Wipe data/factory reset
2. wipe cache partition
3. go to mounts and storage menu and\
4. format /system
5. format/data
6. format cache
7. exit mounts and storage menu

ok first since ur stuck flash back to stock using flash tools n then follow the procedure.. i had a similar problem n i fixed it.. it was a very simple prob.. for installing these custom roms u ve to format system/ , so if ur using the cwm app by pvyparts ul loose the cwm after wiping it.. all u ve to do is after flashing the custom rom ul ve to install CWM back (use cwm version 5 available in the thread by pvyparts.. not the latest one..)
here's the thread for CWM
n post back if it works..

Thanks guys, really appreciate it, will try these methods out.

Still won't work
I tried doing all the different things you said but the phone won't boot holding in the back button and inserting the datacable. The light on the side turns green but nothing else happens.

Mate, press the back button while you connect to PC and flashtool will show "device connected in flashmode" than select a firmware to FLASH and FLASH it. After the process is done disconnect and power it on... =)

Yeah, that I know and that's what I'm doing. When I hold down the back key and connect to the pc all that happens is that the green led lights up. Flashtool won't recognise it and it still says that I should hold down the back key and then connect to the PC...

I was also stuck at Sony logo and it reboots every time just after sony logo. Then i used flashtool, flashed using "LT15i_4.1.B.0.587_Kernel.ftf".....
Now it boot further, but only to XPERIA logo, and then reboots....but certain times i have seen it getting past the logo, like it shows a display asking for pc companion, even the taskbar too with time and blutooth icon on it....but all of a sudden it reboots. i have tried rebooting more than a 100 times, while taking out battery everytime.
Also, I'm not able to get into recovery mode. I tried this using the combination of power on, and when sony logo appears, pressing and releasing volume down repeatedly. I hope i'm doing right.
So what should I do?? am not able to use this phone for a week...
Please help me out.
Ok got it working. I just unlocked the boot loader from sony bootloader site(sorry couldn't post the link, because of low post count)
So, it booted up but show error as soon as put a sim, that "Unfortunately keypad has stopped working".
I figured out the culprit, it is the build version with i flash it. I reflashed it with LT15i_4.1.B.0.431_kernel.ftf, now it working fine like a charm.
So much relief...!!
Hope this may help someone too...so i shared!!!

[Q] Bricked Xperia S??

Hi,
First time poster here. I've done a lot of searching to find people with the same problem but can't. Sorry if it's out there and I've missed it.
Essentially I’m worried that I’ve bricked my Xperia S (running ICS). My problem is this:
First I rooted using this link: http://www.xperiagamer.com/Beginners-Guides/rooting-xperia-s.html
Then I installed CWM Recovery using the RecoverX project: http://forum.xda-developers.com/showthread.php?t=1773227
Then I tried to flash cyanogenmod 9 but failed.
I saw somewhere that it mught help to flash XTXperience so I did that. This failed and my Xperia S boots up to the Sony sign then fails and starts again just cycling through.
I can't get in to fastboot mode via CWM or otherwise. When plugged in to the laptop it is recognised but the computer can’t find the drivers (I've tried to instal manually) and then the phone reboots so the computer can no longer see it.
Can anyone help please??!!
Thanks

Keep pressing Unlock key + Volume Down key until you get 3 vibrates.
The phone is now off and you can connect it into flashmode and reflash your ics firmware.
The other thing you can do is going into CWM and wipe data and cache (that worked once for me when I had a bootloop)
--> you will lose all your data.
For CM you first have to install the kernel via fastboot and then go into CWm and flash the CM.zip file.

Thanks but that doen't seem to work. All i can get it to do is turn off with power and volume up. When it comes back on again it just cycles through again.
Can't get it to communicate with the computer at all - it recognises it but can't find drivers. then the phone disconnects itself in the reboot.

Yes I can connect to flashtool in flash mode. Sorry I'm a bit lost on where to go from here. All help greatly appreciated at this point.

If you can find a way to copy a ROM file into the fone we can flash it. The fone isnt being recognized by the PC , but the CWM works and it cannot mount as a USB Storage as some lunfile is missing . I am also on the same page and struggling for hours

A tip for the newbies out here:
Read everything carefully. Chances of bricking a Sony device is quite low because of Sony's dev support but you will have moments of anxiety and lots of torn hairs. As a way to start, please go through all the top stickied posts in the Dev section and understand what are the many processes happening. It doesn't take more than a couple of hours to go through them but in the long run, helps you to enjoy your device better. Hope you will have a good time with the S

Which cwm recovery do you use ?
Afaik its related to recovery .

i don't remember what recovery i had installed, and i don't have access to the phone right now.
i only remember it was a custom recovery with blue UI and that the power button was "back"
there is any recovery is should flash instead?

I had this with my wildfire, and it never really bothered me lol. Anyway it sounds like you have clockworkmod version 5 or above.

It happened to me as well. The work around is to switch the phone on before charging it. Once you reach the bootanimation plug in the charger and it should work as normal. BTW I am using cwm 4. If your phone is completely dead (ie it won't switch on) then plug it in for 15 mins, unplug it pull out the battery and then switch it on and charge it for the remainder.

It's a problem with Clockworkmod 4.0.1.4. Use one of the newer versions like 5.0.2.7. Known problem, offmode charging bug

You are right,but cwm 4 is stable,and support Aroma install

cwm 3 also is totally stable and supports aroma (; probably this is a bug caused by rooting and cwm and u can't change it

actually your have to first select the rom in flash tool then "wait" for tool to prepare files then the tool will prompt then connect your phone

My ZL has been acting weird lately, powering off on its own, and requiring a power source to boot back up.
I tried connecting to flashtool last night, and it works, but the green led that supposed to light up, just quickly blinks on then off, and stays off.
Yet flashtool is still telling me my device is connected in flashmode..... weird.
I was too scared to try and flash an FTF because i have a feeling the phone will just randomly power off.

My LED does the same, just blinks on and off when connecting to flashtool.
When I connect in flashmode and wait for a minute or so, the phone boots automatically.
But it always behaved like this since I bought the phone .
Flashing works like it should and it always worked. I think it's normal.

okay, ive got another problem. Im trying to unlock my bootloader via flashtool, and after connecting my phone with the volume down button pressed, it does nothing, just asks me to re connect my phone. Any idea whats wrong?

Flash doomlords kernel via fastboot....then reboot to system....if it will not boot successfully then push a ROM zip by adb push and flash it....one more thing just check whether your phone is connecting to PC via fastboot or flashmode.
.
The best way to check is by flashtool...open flashtool software on PC and then connect your phone via fastboot/flashmode and see the status at PC flashtool....if its connecting then flash stock ftf and if not then 1st install drivers..

As far as I know, it is not possible to wipe partition from CWM (if You selected from one of the options from menu) which would lead to hard brick.
Let us start with basics. Can You tell Me which kernel You flashed to get CWM? Also, is there any vibration when You press and hold power button and volume up key together?

Huh, that kernel should have worked. I asked for the combination duration since many people make mistakes there. Since we are clear of that, did You try the rubber band trick from here? That trick sometimes takes more than a day to work.

Yep i did that and i tried many different ways to make it work.. no luck. i got annoyed and i sent it to the repairs today...
