[Q] CM9 problem Bricked phone (no response at all) - Sony Ericsson Xperia Neo, Pro

Hello
My phone: sony ericsson experia Neo (MT15i)
I tried to instal CM9 but something went wrong and now i cant start my phone.(normal, recovery nor fastboot)
I downloaded CM9, extracted the boot.img file, and placed it in the fastboot folder.
Then i placed the Zip and the google apps on the SD-card.
I then rebooted the phone in Fastboot and flashed the boot.img file.
Everything looked like it went fine but the phone wasn't rebooting. I've tried alot of things now but nothing works.
The only thing that happens when I try to put on the phone is the slight vibration in the beginning and then nothing happens.
Can somebody please help me? I cant even go in recovery with CWM

I also had this problem with CM 9. You just have the flash the old kernel back. Or you can flash the whole firmware again: http://talk.sonymobile.com/thread/35239
Edit: with Flashtool.

I would have tried that, but the problem is i cant go into flashmode anymore. Nothing works.

Fastboot?

Doesn't work either

Follow these steps
1.Download Sony Ericssion Update Service (SEUS)
2.Hold the volume down button key of ur phone and connect to the USB connected to your PC
3.If this does not work remove the battery and put it back again and do step no 2.
4.SEUS will detect ur phone and install the latest ICS i.e.4.0.4
5. U will have a bootloader relocked and rooted phone :fingers-crossed:

2)why volume down?
5)seus nor pcc doesn't relock bootloader, plus if he unlocked it via official way, he won't be able to use pcc nor seus.
@OP: what happens when you try connecting in fastboot mode? No blue led? Hows your phone named in device manager?

@madfysh
I had the same problem with that CM9 kernel and I had unlocked bootloader & I recovered my phone using SUSE by the same process I wrote that's y I suggested him those steps

I will give this a try.
I think there might be a problem with the Trim Area though. I have been looking for a solution but it seems hard.

I was thinking there was a trim area problem so I was looking for a solution.
At first there was nothing, no device recognized when I attached it to a pc. No flastboot, no flash, no recovery, no leds, nothing at al (exept for a slight vibration in the beginning).
Then I followed the method for unlocking the boot loader with testpoint and then te pc recognized the device as a neo. But thats all. Nothing more, stil no reaction when i try to turn the phone on in any way.
I disconnected the device and now when I reconnect it it isn't recognized anymore.

Use Flashtool, flash an Official Global ftf from SONY, then let it boot up. It will work. Only way to do it. PM me if needed
Is this the OFFICIAL CyanogenMod 9 RC1? The boot.img does not work. Use the boot.img from FXP's Unofficial CyanogenMod 9. It works. Personally though, use FXP's CM9 cause it's working better then the official one.
Before using the full restore method (The Flashtool thing) try flashing the boot.img from FXP first. Still doesn't work? Flash official, boot-up, turn off, flash FXP kernel, full-wipe, flash ROM, reboot.

My Phone is fixed.
Alejandrissimo helped me with rebuilding the Trim Area.
Everything works fine now, except connecting to 3G/HSDPA. I used to be able to connect to it but now it doesn't anymore.
Does someone knows a solution for that?

bricked

Please Help, tried to Flash phone, Error phone Cannot Reboot.

Hey Guys, I hope you are having a good day. Mine is not a good one.
I wanted my experia st15i phone to be back on stock again so I can root it. I am running a .62 firmware. I have read on doomlords thread that .62 firmware cannot be rooted, so I decided to flash it back to the stock phone .368.
I followed all the step on the flashing on the phone.
-downloaded the flashtool for experia latest version. Followed the steps
- installed the necessary drivers -adb, flashtool drivers.
- then I followed the steps to flash the phone
This error came up (see Attachment) after that I haven't been able to turn on my phone since then. Even If I tried again, still comes up the same error.
BIG PROBLEM! My phone now cannot be turned on, it keeps getting back to flash mode whenever I connect it to the computer.
Please help!
I am sorry but I only follow steps throughtout the flashing method, I don't know if I had to unlock my bootloader before I flash it, or root it.
Please help, I am currently researching now If I can turn back my phone again.
flash to stock rom.. .42 firmware is good if you want to keep root..i saw the image from that are you flashing any kernel..?beacause you are in fastboot mode..but to flash ftf file you have to be in flashmode
Error with the flashtool, phone stop working
No, I am not flashing any kernels. I was in flash mode. I was never in fastboot mode.
Ok thanks for the heads up, I'll use .42 instead.
But still currently having this problem. I can't do anything because I can't turn on the phone. If I turn it on, the logo doesn't come up and the blinking light is on GREEN, so that means I am still in flashmode (even without the connection to the computer). If I connect the phone when the flashtool is there, its says on the log that it's on flashmode.
The Big Problem is, How can I turn it on back to normal mode. releasing the flash mode. If that really is the problem, when the error came up.
Second Question. Do you have to unlock the bootloader to perform the root or flashtool. I already have installed the adb drivers.
first there is no need of unlock bootloader to flash ftf file..just download ftf file then put in firmware folder..then open flashtool... click on flash and then click on flashmod then just select your ftf file and press ok..switch off your mobile..then press volume down button and coonect your mobile to pc using usb cable..flashtool will flash that firmware...
Thanks...
But, I have already followed all those steps you said. then that error comes up (refer to the thumbnail above). After that I haven't been able to turn on the phone.
When I try to turn on the phone, the logo screen won't show and the light that blinks above the phone is green. Meaning its kinda stuck on flashmode.
I am so scared right now, if I can't fix it.

Can you explain with more detail about "connecting to flashmode in flashtool" ?
I read in some posts-connect your phone to flashtool and flash the stock firmware files to get back your phone
I connected my phone with the volume key down to flashtool,but it stated an error and didnt proceed..
You erased everything, obviousely. But Flashtool should still work.
I'll go searching for a user who I know already did the same as you... maybe he'll have useful information
EDIT
Which error?

Which sony logo, The first at boot or the boot animation one?
Are you able to boot your device in clockworkmmod?
Ok, let's do this:
-Start Flashtool
-Plug USB cable to PC
-Turn off the phone
-Press and hold volume down button
-Plug microUSB to the phone
-Post the complete Flashtool log
By the way, did you install flashmode drivers?

He formatted everything, CWM included.
I installed the flashmode drivers..
It gets stuck at the black sony logo at the start and does nothing,I had to switch it off after removing the battery..
When I connect the phone in flashmode,it says error and says device disconnected and then the phone remains at sony logo..
I'll post the log soon
GOOD NEWS!
I tried flashtool again and this time it WORKED!!
THANK YOU TO ALL
p.s-Now I'm on stock GB .58
Try to flash a different ftf file and see, preferentially an old GB Build.
If this doesn't work,
Try updating to latest Flashtool.
Install the exe at /flashtool/drivers folder.
Then flash again.
Thanks,
Rick
Edit: Okay, never mind. It's done.

[Q] Xperia U stuck in boot loop (more in the post)

Hello everyone,
I encountered a problem while flashing a new rom on my new (actually 1,5 years old) Xperia U.
I rooted it and managed to instal the CWM touch recovery (using the CWM-instaler) and when i tried to flash a new rom (eXperiance V2.1)
the rom stopped installing (it has a special installer where u select apps and stuff, u probably know of it) and it didn't move on... i had no other option but to take out the battery. When i tried to turn on the phone again it just showed the sony logo, then automatically restarted, showed the logo again for a few seconds and restarted, and kept doing that until i took out the battery again...
So i tried the flashtool and i can connect the phone in flashmode (green led), but i cant connect it in fastboot mode (it connects but then suddenly disconnects as the phone restarts). I wanted to flash a new .ftf file but somehow when i put my file in the /firmware folder and turn on flashtool it is not visible in the files i could flash (just the stock x10 file is there) so im really at a loss...
Anyone got any ideas?
i did backup my previous rom but since i cant boot my phone into recovery that's not a lot of help...
I might also mention that the phone was running ics 4.0.4. and that the bootloader was locked ( i did have root tho...)
If you want any extra info just ask
Any help would be appreciated thank you
Solution: I did what dara007_168 said, which was:
1. Put the file into folder firmware(make sure the file is FTF
2.open flashtool don't do anything
3.select lightening icon and select flash mode then select the download firmware
4.wait for the pop up said
"Turn off your device....."
5.turn off your Xperia u at least 30 second
6.press the volume down key with the same time connect your phone to computer via usb (make sure to have driver install)
7.wait till it finished done
at first this didn't work for me since i had some problems with the flash tool but then i re-downloaded the older version of the flashtool and the firmware and also reinstalled the drivers.
After that it worked and i could normally flash the generic firmware.

How could you flash the kernel with a locked bootloader?
Have you installed the drivers from flashtool drivers directory, what windows version you have?

Bro u can't flash custom kernel when your bootloader is locked the only way to fix it is to flash back to stock rom via flashtool or Sony update services

Sorry for no reply for so long but i made a video and here's the screenshot of my flashtool
I am using Win 7 64x and i have installed the drivers in the flashtool driver directory.
There is a chance the phones bootloader was unlocked though... i didn't check (honestly i didn't know how)

Thanks for trying to help
(sorry i haven't got enough posts to post links)
Edit: I tried using sony update service and it gave me an error stating that the software installed on my device cant be updated... probably becouse it has a half of a custom rom flashed, or am i missing something here?
Bro I think you should flash stock firmware. I think u know how to use flashtool that easy.
1.charge battery until it full i don't know if u can charge battery or not but u should
try. I have the same problem by flash the same rom as your but mine is different it stuck on the boot animation so it can charge but u I don't know
2.download stock firmware
3.flash it

Firmware is flashed in flash mode not fastboot, see how long can you stay in flash mode, though fastboot should be on forever.
Did you unlock your bootloader?
@ dara007_168 I think the phone should be reasonably charged, since i started doing things on it with a full charge and didn't really use it much, so i don't believe that's the problem. I downloaded the firmware u said and again i have the same problem with flash tool... i put the file in the correct folder, but when its time to flash it to the phone (which is correctly connected) it just isn't there, i cant select the the file i downloaded.
@ ChikeD The flash mode stays connected for about 45sec and then it goes into boot loop and about the boot loader i actually think i managed to unlock it a few hours ago (i did the necessary steps on the sony site and got the code before i bricked the phone) and now i entered the number in the flash tool and i think it actually did unlock my boot loader... although i don't know how to check that...
Oh, and fast boot mode stays on forever i think (ill let it charge a bit in fast boot mode, since the red light beside the camera is on so i think its charging)

Yow man, thanks for helping me out like this but there is a problem when i try to do those steps.
At step 3. I select the lightning icon, and the small pop up window appears and i select flash mode, and then
the window opens called Firmware selector, but the firmware is nowhere in that window and i don't know why...
i know where it should be i checked some videos it just isn't there...
Would it help if i posted screenshots of all the steps?
ow and another thing.
would it work if i tried to use fastboot and flash a kernel from that option? or maybe even flash the firmware?
And i guess this might be a useful peace of information, i am using Flashtool Version 0.9.12.1 built on 2013-06-04 22:50:00

There are many ways to get your phone into working condition.
1. The first thing you should do is, try repairing your phone through PC companion.
2. If your fastboot mode is working and have unlocked bootloader, try flashing stock ftf ROM into your phone via flashtool.
3. Try flashing recoveries via fastboot and then clean reflashing ROM
Let me know if you have problem with above
Regards,

pc companion can't find phone
flashtool (emma i found it on sony site) is not supporting xperia m
Is there any specific error, when you connect your phone to computer?
Try factory resetting phone through stock recovery. It might help you.

Flashtool only detects fastboot mode, stuck on Sony logo

Hi there,
my mate gave me his Xperia Z2 asking if I could fix it. He said it's stuck in boot loop. I thought it'd be an easy fix but I am experiencing a problem that I think (I hope I'm wrong) is hardware related.
The phone is indeed stuck on the sony logo and won't go past it. It responds to power+volume up (buzzes 3 times). I can put it into fastboot mode (blue LED, flashtool recognizes the phone in fastboot mode). However, I can't put it into flashmode (LED goes green, but flashtool doesn't recognize it, Windows and Sony Companion doesn't either btw).
Has anyone had this problem before and knows how to fix it or is it indeed a hardware issue?
TIA guys
Cheers
Edit: All the drivers are installed, I have tried two different computers, previous flashings were no prob.

Is the bootloader Unlocked???
If yes then try flashing a kernel that has built-in recovery and clean flash a new rom
It may helps
Hi, thanks for the reply. I'm afraid the bootloader is still locked, tried to flash a kernel already, it won't let me so I assume it's locked.

Maybe you can unlock bootloader and then flash a kernel(try it at your own risk)
Okay, thanks, will do that. I would have liked to find a way without unlocking the bootloader (wanted so save keys first) but it seems that it's the only way since I can't make it into flash mode. Will give an update after!
Hi there.
Unfortunately I couldn't unlock the bl. I assume, USB debugging isn't enabled. Any ideas?

I think there is some gadgets out there that will force your phone to boot to flash mode(im not sure) or you can search "how to force Xperia phone to boot to flash mode" it may helps
If you cannot access fastboot or flash mode there is nothing you can do
Cool, will do, thanks.
Just to clarify: I can access fastboot mode fine, it's just flash mode that isn't recognized! Will post an update.

Ah, I see. Well, anyway, I tried to find a way to force the phone into flash mode but nothing worked. Very annoying but I think I'm gonna call it quits.
Thanks for your help anyway, appreciated!
It seems like a firmware issue than a hardware one.
It's either falshtool compatibility issues , a soft-bricked phone or both.
1 - Try using an older version of flashtool like 0.9.18.6 and see if flashmode works.
2 - If you know the current firmware version
you can just flash the stock,signed kernel via fastboot.

Are you sure you have the proper flashtool drivers installed? What's the Windows and Flashtool version? And have you connected any other Xperia device in flashmode mode to the same pc before?
I am saying that it is 90% a driver issue..
-Try disabling Driver signature on Windows 10 or 8 then reinstalling Flashmode AND Xperia Z2 drivers from the folder drivers in the main flashtool folder, then restart the pc..
- Try connecting a different USB cable
- Try connecting to a different USB port..
- And when you want to flash the firmware.. Select flash.. Select the firmware.. Check the wipe options (optional).. Press flash.. And after that when flashtool asks to connect the device in flashmode connect it.. Do not connected it BEFORE pressing flash..
Hope this will help you.. Have a good time..
Bye
