[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.

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

[Q]Touchscreen, menu, back and search keys dead

*snip*

Christophelaures said:
Hello people,
I've got a problem on my phone. The touchscreen isn't working, the back key, the search key and the menu key aren't working anymore.
I don't know whats the problem, the software part of the phone seems to work (everytime I start the phone, I get into recovery (automatically, I don't know why)) I can flash zips and I can navigate trough the recovery using the home key and volume buttons or using the gamepad. I entered the key test, and I pressed the three keys there, but I didn't say anything. I also had some zips using aroma, and there, the touchscreen didnt work either.
Last time I used the phone, I did work well, but then I started an emulator and slided the gamepad out; at that moment the keys(only search at that moment I believe) and the touchscreen weren't working anymore. I restarted the phone, and now I can't boot into the rom, it always puts the phone in recovery.
I was using the MIUI Australia Rom by Cosmic that with the kernel which came with it. Once it didn't work anymore, I tried flashing another Rom or reflashing MIUI again, but naturally, that didn't help. I can't enter fastboot mode or flashmode, since the needed keys don't work.

Had this problem before but it was my home key that died. Could not enter flashmode either to flash back a stock ftf. How I solved it was doing an update with Sony Update Centre. All my problems had disappeared. Same thing happened ti another user on here a few months back, he solved it the same way I had.

With PC companion I'm pretty you don't need the OS all you do is hold back with the phone off and plug it in to a pc and wal-la it will walk you through the rest bit I think you need USB debugging on for it to do that though I'm not sure....I never used it

[Q] Mysterious problems with used Phone... HELP!

Hi guys!
So, my sister got a Galaxy Ace II yesterday with some ode stuff, then I decided to install Cyanomod 11, BUT more problems appered:
1 - My Windows 7 (64bits) doesn't recognize the drivers.. so it no even list the phone as conected. I tried using Kies to detect and a bunch of packages of drivers of this smartphone model, but till now haven't made any progress... what can I do?
2 - I reseted the phone to original especifications by his own menu and tried to acess its Download and Recovery mode by pressing the 3 buttons at the same time(Vol UP + Home + Power), but for my surprise it didn't boot like it should, jus initializing normaly...what can I do?
3 - I realized, when it booted, that the boot animation has been changed, samsung logo doesn't apper ever and including I found some stuff installed that doesn't seem to be something that generic stock roms have instaled; this made me think that the room installed is not its stock. If that's so, maybe the problems listed above are resolved, but still so I don't know what to do...
I want to install Cyanomod 11, but need the phone recognized for Windows, it rooted and in download mode, but haven't find a way to begin if my computer doesn't reconize it...
Any Help?

Yes, I hold the 3 buttons at once and waited to it boot, but it jus performed the normal boot, it didn't get into download or recovery mode... I tried many times, but it's always the same...
And I know that CM has it's own boot animation, I know it, but it's not it this time... it's another one... and for what I know, it's not the samsung original one...

Having Kies installed is counterproductive to installing flashing drivers (and if you sync contacts and calendars with Google I can't even think of why you need it :angel
Try unplugging the cable while entering recovery, the LPM mode (charging while "off") screws it up (but download mode should work!)
And by "no Samsung logo", you mean not even the firmware's "Samsung GALAXY ACE 2 GT-i8160"? Sounds like you got a fake then...
But if it boots, you should check the Settings/About menu and tell us the "build version", often that's enough to know what ROM is on it now

About that trick could you be more especific? Do I put the phone off with the cable plugged to PC and when I press both 3 buttons I unplug it?
About the version it is :
DM_BASE_12A_W12.43|sc6820_modem|11-02-2012

Recovery mode is: with power off, hold up+home+power (if it's on, it will reset since you're holding down power... keep holding it) and download mode is the same with down+home+power...
But that version is VERY dubious, the standard Ace never had "SC6820" (maybe it's the L model?) and I don't even think it was out at the start of 2012...

2nd post there mentions "Star I8160"

You surely can't use roms from these forums... There may be other roms for your device but you'll have to find out what it actually is first, which can be somewhat difficult...

[HELP] Soft brick ZL C6506.

Hi All,
If you have some experiences with some situation like this, pls give some advices.
I have my Zl, upgraded to 5.1.1 (10.7.A.0.222) , it work fine for some week, then usually shutdown suddenly, 5.1.1 upgraded from 5.0.2 with rooted, installed xposed and some modules (but not unlocked bootloader) .
After some random hanging and rebooting, i try to flash brand-new from ftf file .
and BTW, i unlocked bootloader, after flash new ftf, system cannot boot up, only show up the Sony logo, then down, after that fastboot and flash older ftf ones normally , event i try to relock bootloader.
while unlocked bootloader, i try to install CM ROM, flash boot.img one but still not up.
While connect the charger, logo sony blink for every 10s (estimation) .
I consider the TA partition affected to booting processs. (i have backuped TA but still don't know how to restore via fastboot/flashtool)
Thank and appricated for reading till this point.
Hope you can give me and someone who encounter this situation some wise advices , i will report each try
This is more clear explanation (just read this ):
My case:
1./ first version is 4.4.2, then i try to flash to 5.02 via flashtool (as i remembered i flash ftf version for Generic US)
2./ Then root/install xpose .... and update to OTA (failed), success with updating via Sony Companion, after that, backup TA.
3./ using normally for some weeks, then occur suddenly hang, reboot, lose signal, i commit to flash a brandnew one
4./ After that i unlockbootloader via sony site, Flash 5.1.1 (10.7.A.222 but customized os)
5./ Try some solutions:
5.1/ (unlocked bootloader)Try to flash some other custom kernel (ex: CM12 kernel, one in this dev subforum) but the symptom as case 5.2 below
5.2 try to relockbootloader install the 5.1.1 Generic US/Customized US still doesn't boot up,
- Unplug charger, press and hold power butter, red light blink for 3 times (although connected to charger all night)
- Connect to charger, not show up the charging progress bar, just blink Sony - Xperia around every 10 s
Still consider to battery issue , hope to hear any experienced/wise advises

TA Partition, what's that?
Emma bring you back the original Sony stock Rom without root. Bootloader will be untouched. Have fun...

I really need your help guys. My ZL got updated yesterday, and then a random reboot. After trying to repair it, it keeps getting into Flashmode direcly.
It does not boot into system, but flashmode. Tried to repair again with PCC, no luck. I don´t know booting process to figure out and get out of bootloop. I can access fastboot, flashmode, TWRP, with UB. I flashed ROM a couple times via TWRP, but no luck again.
I think something is messed up with partitions or something.
HELP.

Did you try to flash stock rom with flashtool?

Yes. Phone boots into system now, but only when plugged in charger. If I unplug it, it will shut down.

You mean you cannot boot up, stil flash the logo while connected to charger right?

My case:
1./ first version is 4.4.2, then i try to flash to 5.02 via flashtool (as i remembered i flash ftf version for Generic US)
2./ Then root/install xpose .... and update to OTA (failed), success with updating via Sony Companion, after that, backup TA.
3./ using normally for some weeks, then occur suddenly hang, reboot, lose signal, i commit to flash a brandnew one
4./ After that i unlockbootloader via sony site, Flash 5.1.1 (10.7.A.222 but customized os)
5./ Try some solution
5.1/ (unlocked bootloader)Try to flash some other custom kernel (ex: CM12 kernel, one in this dev subforum) but the symptom as case 5.2 below
5.2 try to relockbootloader install the 5.1.1 Generic US/Customized US still doesn't boot up,
- Unplug charger, press and hold power butter, red light blink for 3 times (although connected to charger all night)
- Connect to charger, not show up the charging progress bar, just blink Sony - Xperia around every 10 s
Still consider to battery issue , hope to hear any experienced/wise advises
