[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.

make sure in cwm before installation
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

towelroot not
towelroot no working em xperia T2 dual

Towelroot works fine in T2 Ultra Dual.
First install SuperSU from Play Store
Enable USB Debbuging
And then follow towelroot steps.
And if you get stuck in a 'Clean' message on the prompt,just disable and enable USB Debbuging without disconnecting your phone.
It works for me. Try it for your own risks.
Sorry for bad english.

What version do u have?...If its 4.4.2 then u must try EasyRoot Toolkit. It works like charm.

The only method that worked was this:
In the 19.1.1.C.0.56
1. flash 4.4.2 stock kernel
2. root by Easyroot tool
3. flash 4.4.3 stock kernel
4. Install recovery
5. Flash Supersu on Recovery

select all options except the kernel and uncheck data. After giving Flash the kernel 4.4.2, the screen will turn black, so this leaves the USB enabled before the deputation process. After restart, wait for 10 minutes and do the root.

Yes...after flashing the 4.4.2 kernel...the screen will be black...so after switching the phone on.......wait for 5 minutes with the black screen...and then root it with the easyroot toolkit. and flash back the 4.4.3 kernel....after rooting is done switch the phone off..if ur having hard time switching off the phone cuz its black screen.....then do this >> prepare the kernel to flash......plug in the usb when ur phone is switched on.........now when flashtool prompts you to connect the phone.....switch off ur phone with pressing the volume up button and the power button.....when the phone reboots immediately press the volume down button and the kernel will be flashed...

Here is what to do in order to get your T2 Ultra Dual rooted:-
Assuming you are on stock KitKat 4.4.3 ROM. First thing you need to do is.. You need to enable USB debugging and Installation from Unknown Sources....Accept your computer on the phone screen if it prompts to do so...check these thinigs before u flash the 4.4.2 kernel cuz afer flashing it u will endup with a Black screen and wont be able to do the changes.
1) Flash the 4.4.2 kernel with Flashtool.
After flashing is done ...reboot your phone.....your phone will boot with a black screen on....you would be able to hear the boot up sound tho and the touch sounds as well when u press the volume rockers. Wait for the phone to boot properly with the black screen for about 5-10 minutes and then move for step 2.
2) Root your phone.
While its with a black screen but u have already enabled USB debugging and Installation from Unknown Sources ...You are good to go...Just plug the USB in and root your phone with Easyroot Toolkit....Move to step 3.
3) Finally Flash back the 4.4.3 Kernel.
Now this is the final step to get your monster rooted with 4.4.3. You need to flash back the 4.4.3 kernel so prepare ur Flashtool and wait untill it prompts you to connect the phone. The phone is with a black screen so there is no way you can normally shut it down with the soft keys. So this is what you are supposed to do. Connect the phone to the PC while its "Switched On" and press the "Volume Up" Button and the Power button together (Hard Reset) ...The phone will reboot...but here is the trick....You have to press the Volume Down Button before the phone vibrates and reboots. If the phone reboots..Flashtool will not detect it...So press the volume down button at the right time....right before it vibrates..If you can find another way to switch the phone off....that will be more easy....atleast i couldnt find a way lol.Once you successfully connect the phone to Flashtool it will flash back the new kernel and Voila!! You have Root with KitKat 4.4.3.
Show me your Love once You succed

thank you so much for your detail instructions, i will going to try again and back to you, i think i tried to root my phone while it was in black screen but it was not success anyway i will try it again..

HELP Needed - Sony Xperia M Dual on BootLoop after Bootloaded Unlocked

hi guys, need some help here. I'll try to keep this short and precise to describe how i ended up in the problem
i did not have (and do not have) any custom recovery installed before this day, never needed to go in recovery mode.
1. Root using TowelRoot app (no problem so far)
2. Installed SuperSu app (no problem so far)
3. Unlocked bootloader using Fastboot and followed official sony guides
---after unlocking the bootloader, phone went in bootloop. It can go in Fastboot mode. It can go in FlashTool Mode, but when I tried flashing FTF file, it ended up in boot again. instead of Sony logo + colourful animation. now it's stuck at sony logo only.
I tried using Sony PCC, to repair it but it says there's any error, can't proceed - it's a dead end.
Do you think it's cause I actioned in incorrect order i.e. should have unlocked bootloader first before rooting?
Thanks for all the help/advices/direct links.

3. Unlocked bootloader using Fastboot and followed official sony guides
---after unlocking the bootloader, phone went in bootloop. It can go in Fastboot mode. It can go in FlashTool Mode, but when I tried flashing FTF file, it ended up in boot again. instead of Sony logo + colourful animation. now it's stuck at sony logo only.
I tried using Sony PCC, to repair it but it says there's any error, can't proceed - it's a dead end.
Do you think it's cause I actioned in incorrect order i.e. should have unlocked bootloader first before rooting?
Thanks for all the help/advices/direct links.

What model xperia do you have?
What did you do to your phone? Did you try and flash a boot.img or something.
Need more detail to help fix.
Maybe power off your phone. Hold down vol- as you plug USB cord and maybe PC companion will then see you phone
Or maybe
Download the phones firmware as a .ftf file
Flash firmware with flash tool.

I Have the Sony Xperia M (C1905)
I try to put the cyanogenmod android 5.1 and i was following a tuturial in youtube and i have made some mistake or i not did well the flashboot and for some way my phone its looping in sony logo, i unlok the bootloader and now the pc companion dont let me recovery the phone because have a unknow software installed....
exists some way do recovery the boot and the original software without pc companion?
I am very greatfull for the fast response and disponibility to solve this problem!

You said you unlocked the bootloader. Did you replace the boot.img? If so have you been able to get into recovery by holding VOL + while phone starts?
What video did you watch on YouTube and how far did you get?
Unlocked bootloader
Replacing boot.IMG (OK installed recovery)
Enter recovery and flashed ROM.
Have you tried turning your phone off. Open up PC companion. Then connect up your phone while holding VOL - down?
Read the following link it'll guide you through recovering your phone with flash tool.
