Hello, I'm A Young Teen And I Wanted To Get Jelly Bean Stock On My Phone.. I Flashed CM10 Boot.img and got An Xperia play Recovery (BY ACCIDENT) and Flashed It, My Phone Would Work In Fast Boot, I then Had To Go Out. I Came Back And My Phone Didn't Work. When I Plug into USB The LED Tuns Red. If I Charge It Goes Off After An Hour-ish. It Doesn't Recorgnise/Go Into Flash/Fastboot Modes. Any Fix, Is My Phone Dead/Bricked? Please Can You Help Me, This Phones My New/Best One So Far.
Hello I've Bought It From Amazon Sim Free, I've Unlocked The Bootloader And I Flashed Through Fastboot CW10 Release 202 And Lately I've Read The Latest Stable Release Was 154, I Didn't Transfer The OS's Files To My Phone. Could That Be The Reason? I Don't Get A Green LED So I'm Guessing It Can't Flash After What Has Happened, I Was OK Getting Into FASTBOOT.exe But after Transfering The XPERIA PLAY RECOVERY And Boot.img Without The Files Present On My Device I Couldn't, When I Charge The LED Goes Off After 10-50 Minutes. The PC/Flashtool Don't Recognized The Device Only Under Device Manager - Universal Serial Bus Controllers Sony Erricson seehcri Control Device I've Reinstalled Flashtool Drivers ETC.. Thanks

I will thank you but can you give me instructions, I don't seem to get into the fastboot as well as no blue led starts? My phone isn't coming on and It only charges in my PC and isn't recorgnized
Hi guys,
I'm not an Android expert, but AFAIK is a Linux system.
I'm quite familiar with Unix/Linux world and wondering if there's a way to see the messages during boot just like on a console?
I'm asking, beacause my ray hangs at sony-ericsson logo, and can't figure out what's wrong with it.
Thank you!
to solve problem .. flash your stock .ftf again with flashtool
Well u can use adb for that...use adb logcat...search in xda if u don't know how to use adb...it will give u a complete log as u need
Cheers,
AJ

tried to flash stock gb .42 ftf, but still the same, and cwm is gone now, since custom kernel was overwritten by stock one.
regarding adb, all the adb tutorials mentiones to use usb debug mode, but how can I activate debuge mode, once my phone doesn't boot?
thanks.

i think usb debug will not work anyway if ur phone powered off
try to flash custom kernel again , then u will have CWM , then remove your SD Card and put it in reader , then put any ROM in it , then put it again in ur phone , then flash it with CWM , i made that before with CM ROM & it worked :good:
I tried to flash cutom rom with cwm before flashing stock, but didn't work .
The phone is not powered off when flashing, it's either in fastboot or in flash mode.

Do you know why it's not booting? Did you flash a new rom, did you install a special app, did you do an update over the air (using WiFi)? Or any other idea?

I flashed a custom rom.
Actually, i was on ICS, and wanted to try custom GB illuminative.
Flashed the v10, everything was fine, but Ant+ wasn't working, and dev of the rom was helping me to get ant+ working on the device, so he added things to rom required for ant. I did flash some times the rom without issues, but the last was unlucky .
By that time, my BL was locked, so I had to root my phone to install cwm.
Interestingly the cwm was gone after each rom flash, not sure why, so I had to take the process over and flashed GB .42, rooted with doomlord, script, installed x-parts, then cwm from x-parts, and then flash custom rom from cwm.
basically these were the steps I was doing, and after a cwm flash of the custom rom, the phone ended hanging at sony logo.
I then tried different kind of stock firmwars ( ICS, GB ) to flash with flashtool and SEUS as well, without any luck.
afterwards, I unlocked my BL, flashed cusotm kernel with flashtool ( containing cwm ) , then flash a version of the illuminative custom rom which was working before, but still the sam. somebody then advised to flash again a stock ftf, I did a stock GB .42, but still the same.
now, cwm is gone, as stock kernel overwrote the custom one.
That's the story .
As i remember i can enable usb debug even phone not boot to system. By charging phone with pc(not standard charger) then hold power button and at windows(or else) will ask for driver
Ps. I did that with X8, didn't know with 2011's phone.

Hmm okay you could try to flash the unbricking ftf (you can find it in someguyfromhell's sticked thread) and afterwards stock gingerbread or ics again, but I don't know if that could work or maybe make it even worse (normally it's to unbrick if you did an ota update on unlocked bootloader, but let's see). Maybe it's worth a try
The problem about cwm that's gone: if you are still able to boot into fastboot mode, you can flash another kernel and for example try to install cyanogenmod or any other rom. Just try cm10 or cm10.1. Maybe in the end a rom will boot
Sent from my SK17i running stock ics (.587)
tried, and still the same.
The only reason I can think of is that I may forgot once to enable usb debugging, and used flashtool with usb debugging off. could that lead to this kind of issues?
How could I enable usb debugging, without being able to start the phone OS?
tried eswawan's advise, but didn't work.
PS. when I connect the phone in flash mode, flashtool says phone connected with USB debugging off.
Is you connect phone(off) to pc then it goes to offline charging mode???

No, USB debugging off shouldn't lead to such a problem
Try to reinstall all drivers for all devices/modes from flashtool-> drivers. Then you turn the phone off, take off battery, wait 15 seconds, reinsert battery, hold volume up and while holding volume up just connect the phone via usb to your pc. The blue notification led should light up now and then you should be able to flash another kernel. Try it again

during my unbrick journey, I did reinstall my windows, and drivers, and didn't help, so I don't think it would make any sense to try once again ...

With the procedure I posted above it shouldn't simply boot to offline charging mode, so maybe it is a driver problem. Try it step by step like posted above, maybe it could work. If not it was worth a try
Sent from my SK17i running stock ics (.587)
what does it mean if it goes to offline charging mode, also what does it mean if it doesn't go?
PS. not sure if it's right, but when I connect the phone to pc, connects in flash mode, even if I don't hold vol down, the notification led is solid green, then the led turns off, Sony Ericsson appears, then the battery with the power sign and finally notification led turns orange. when I short press power button now, the battery with power sign shows up on screen.

Normally while having phone switched off and just holding volume up and connecting to pc the blue led should light up and you are in fastboot mode. If it goes directly into offline charging mode are the wrong drivers installed or you do something wrong or phone is hardbricked...

Umm...as much as I cud understand....u have used sus before flashtool with unlocked bootloader which MIGHT cause the problem...Try these steps(@mihahn though mentioned earlier) -
1. Uninstall flashtool and delete everything related to it.
2. Now reinstall it to your c: drive.
3. Go to C:/Flashtool/Drivers and install flashtool-drivers.exe with all the drivers.
4. Now download this http://www.multiupload.com/Q103V01CV1 and keep it in C:/Flashtool/firmwares(delete everything present in it already)
5. Now start flashtool.
6. Remove battery from your phone and keep the battery out for 15 sec.
7. Reinsert the battery hold down vol-down button and connect your phone to usb cable connected to pc.
8. Now click on the flash icon and select flashmode and flash the files.
9. Now download this - http://www.mediafire.com/?2j7i7rruqxnui3q
10. Now keep it in firmware folder. REMEMBER to delete any previous files prent in the folder.
11. Now go to flashmode in the same manner and flash it.
12. Now boot your phone, it must start

Sorry, I think I wasn't clear enough. I thought I should be connecting the phone without holding any of the volume buttons, just to try if it's charging in offline mode. Here's the exact status.
1. If I do not hold any volume buttons, the phone goes into flash mode ( solid green led ), and after a short while ( 20-30 sec ) led turns off, Sony Ericsson logo shows up, then goes away and battery with power sign is displayed when I short press the power button
2. if I hold vol down, phone behaves the same way as at 1.
3. if I hold vol up, phone goes in fastboot mode ( solid blue led ) and stay solid blue, it is not going into charging mode.

I may not be clear enough here either. I didn't use sus after unlocking BL, I know it bricks he phone, anyway, I did flash the unbrick ftf mentioned by mihahn. here are the steps I did so far :
1. I was on ICS ( Iced Bean 3.4 ) , with BL lockedand phone rooted and wanted to try custom GB illuminative.
2. I flashed the rom with cwm, and everything was fine, but Ant+ wasn't working, and dev of the rom was helping me to get ant+ working on the device, so he added things to rom required for ant. I did flash the rom several times, without issues, but the last was unlucky .
3. Interestingly the cwm was gone after each rom flash, not sure why, so I had to take the rooting process over and flashed GB .42, rooted with flashtool, installed x-parts, then cwm from x-parts, and then flash custom rom from cwm.
4. and after a cwm flash of the custom rom, the phone ended hanging at sony ericsson logo.
5. I then tried different kind of stock firmwares ( ICS, GB ) to flash with flashtool and SEUS as well, without any luck.
6. afterwards, I unlocked my BL, flashed cusotm kernel with flashtool ( containing cwm ) , then flashed a version of the above mentioned GB illuminative custom rom which was working before, but still the same.
7. somebody then advised to flash again a stock ftf, I did a stock GB .42, but still the same, now, cwm is gone, as stock kernel overwrote the custom one.
8. tried to flash someguyfromhell's unbrick ftf, which is for the FOTA brick whith BL unlocked, as I understood.
9. reflashed stock GB .42 with flashtool, but phone still hangs at sony Ericsson logo.
In this status, could I connect to the phone using adb, so I could do a adb logcat ?
If so, please advise how.
Thanks.
@nroberto13 Do you mind telling us which ftfs u flashed?

Hi
I have xperia neo v 11wxx
- performed unlock with test point (paid service) - all went ok
- flashed new soft with CWM - all went ok - flashed kernel in zip ICS_Spacious_Smooth_Light_ODEX_v2
After flashing phone stays at SE logo nothing happens
I Can't enter fastboot and flashboot mode
in fastboot the diode flashes blue for a sec and nothing happens
in flashboot (flashtool or companion or suse or manul) nothing happens
The phone is not detected properly (in flashtool i have to select my model manual) in companion it say "null"
In flashtool after manual selection it says that the phone flash is emty (no files in /system folders etc) no root ........
In s1tool after identify it gives some usb device error and missing file.
Iv also tried 3 diffrent computers (win8 - with driver signing off, 1x xp laptop , 1x win 7 laptop)
Tried diffrent drivers and diffrent cables
It look like kernel problem. Did you flash a kernel from zip package rom?
When you will want enter to fastboot mode turn off you device and put menu button and now connect phone to PC.

It's good.
It seems like drivers problem.
But when you enter to fastboot mode the led blue flashes every time or fleshes on the moment and off.
If blue led off it's mean drivers problem for me.
I dont understand...if you cant enter fastboot mode,so you cant flash any kernel.My question,how you flash kernel from the zip actually?
flashes on the moment and off
iv tried many drivers nothing works
iv flashed zip in CWM

Try to do hard reset. Remove the battery for 15 minutes.
Or try connect your phone to the mains without the battery for 15 minutes.
I see...actually you are not flash kernel,because kernel cant flashed through CWM.kernel ONLY can be flash through PC...

Your phone is not bricked. Had you unlocked your bootloader? New kernel can only be installed with unlocked bootloader in fastboot mode.
Open PC companion and select update phone, then remove battery, wait for 30 seconds, reinstall battery and connect phone to PC while pressing the back button, now follow instructions on PC. If this does not work you will need 'Sony_Ericsson_Update_Engine' which is no longer available on Sony website. If your bootloader is unlocked then you can install the stock kernel through fastboot mode and then flash stock ICS ROM through flashtool.

When you connect phone to mains does battery is charging?

SUS (not SUSE) not detect phone too? In SUS is repair options.Your phone isn't brick SUS should repair it.
I spoke with a guy who had a similar problem. PC not detect phone and hi can't enter to fastboot mode. His phone has problem to battery. System kept that battery is low (0%). Exchange battery helped.

Hi there,
I have a rooted xperia u with unlocked bootloader. I've tried to install the cm9 following a guide where the requirement of the installation was having an original Sony firmware installed on the device. I didn't saw that requirement, and I installed it with a custom rom on my phone. So after flashing the kernel I turned on my xperia...
Bricked.
It made only the vibration but no Sony logo appeared. So, I connected it in flashmode on my computer (with windowsXP) with green led working, but flashtool gived me the message that I must install the phone drivers (even if I had already installed them on my pc). I tryed to reinstall them but nothing canghed.
I also tried to connect the phone on a windows 7 pc always with flastool (and drivers installed) but in that case neither fastboot mode or flashmode, nor any vibration was working (pc doesn't detect it).
I tried to connect the phone with removed battery or also a reset with power and volume up buttons but nothing...
It's still like this, with fastboot mode or flashmode not working with any pc... :crying:
Is there anything that I can do?
Thanks in advance.
Head to Sony service centre

Sorry Cwikla, I didn't flashed the kernel, but the rom. I wrote it wrong.
Try getting into fastboot. Even without drivers, you might be able to do so. Bring up the fastboot menu in flashtool, then plug in your phone in fastboot. Quickly hit reboot into fastboot (via fastboot). Then flash another kernel and restore a nandroid backup(if you have one)
Hello guys, i have another problem with my M4. After i flashed Xposed (but no wipe cache) my phone does not work perfectly (errors with some application in sd card) and i decided to restore it to stock firmware. The firmware i am trying to use was already flashed other time and it work fine. But now, when i try to get into flashmode the green led light up for 1 second, then light off and another time light up but not stuck into flashmode. I have all drivers on my pc and it recognize the phone as SOMC flash device, but the green led is down and Flashtool not start flashing.... What can I do? Fastboot and recovery mode works fine.

Did you try twrp sideload adb push ?
yes, i tried adb sideload but say a thing like: protocol fault (no status)
Here is some thing that worked for me, even i could not get into Flash Mode.
turn off your phone
run flash tool, select the firmware you want to flash and click flash, wait for the tool ask you to connect the phone.
Now connect the USB cable to the phone with the Volume down pressed and do not let go of the volume down button until the flash process is done.
if the phone is still not detected, do the same but change the USB port.
it happens to me that if i let go of the Volume down button, the phone disconnect from flash mode.
if you are able to boot to home screen then it best to boot to fastboot using the option in Flash tool and then disconnect the USB cable, and then start the Flash process
