Bootloop after flashing SJB 6.0 - Sony Ericsson Xperia Neo, Pro

Hey Guys,
yesterday I took my sisters Neo V to root it and flash Super Jelly Bean 6.0 after that. Getting root with Eroot 1.3.4 was very easy. After that I flashed CWM-Recovery with an App called x-Parts I downloaded from PlayStore. Before rebooting to recovery I did a backup of all her apps with Titanium Backup. In CWM itself I did a Nandroid Backup and after that wiped data and formatted system and cache manually. Then I flashed Super Jelly Bean 6.0 and Gapps package provided SJB's thread. When I tried to reboot the device it got a bootloop. I can see the Sony logo and after that the phone shuts down and boots again showing the Sony logo and again, and again, and again.
As I read in some posts here on XDA I downloaded flashtool and the newest firmware (4.1.B.0.587) from this link right after that. All I got was an error on flashtool, with no further description (look here). I also tried using PC Companion and SUS to repair the phone, but both do not even recognize it.
I really hope that you guys can help me with my problem. Thanks and sorry for bad English

Hey, what you did is essentially wrong.
JB roms > unlocked bootloader. Therefore, you should flash first the required kernel of the rom ( usually provided in the zip of the rom ). Then, after a full wipe ( format data, cache, system... ) in CWM, you should install from there the ROM and Gapss that you've downloaded in your sd card of the phone.
I don't think that your phone is dead, you should try again flashing the ics stock in flashtool. Your pc may not recognize the drivers yet, happened to me in the past, and at the 3rd try it flashed again succesfully.
If it really doesn't work, try again and again with SUS in case that it's a drivers recognition problem.
Tell us how it goes :thumbup:

Hm, on my Desire S that's the way it goes :crying: Think, I have to read instructions more carefully
I tried flashing the ftf-File for about 100 times yesterday, and several times today, getting above error every time. When I connect the device in flashmode and tap devices->check drivers in flashtool, I get the output
Code:
26/019/2013 12:19:17 - INFO - Device connected in flash mode
26/019/2013 12:19:20 - INFO - List of connected devices (Device Id) :

26/019/2013 12:19:20 - INFO - List of fastboot devices :
26/019/2013 12:19:20 - INFO - - none
In my opinion it means that everything is OK with drivers, doesn't it?
Also tried using SUS some more times today, but it still stays at "Connecting your Phone" screen, although it is in flashmode already (flashtool output tells me).

Hi,
Super Jelly Bean is a CM10 ( JB ) based rom.To use a JB rom, you need JB kernel.To flash a JB kernel, you have to unlock bootloader.
If you got bootloop, flash latest firmware with Flashtool.To flash you need drivers.If you haven't installed drivers yet, your device can't be detected.It's in flashtool\drivers-> flash mode + fastboot mode + Xperia Neo V drivers.Its enough I think.
And if you want to use Super Jelly Bean 6.0 rom;
-First Root (After flashing, you have to root again.)
-Unlock bootloader (Unlock your bootloader.Testpoint recommended.)
-See installation instructions for SJB 6.0.If I remember correctly;
-Connect your phone in fastboot mode (Hold menu button and connect phone to pc via USB).Flash -> Fastboot -> Select kernel to flash -> Select JB kernel you want to flash ( Rename kernel boot.img ).Check format .img if you can't find file -> Flash JB kernel (Ex: Lupus (Flash JB..not ICS.) via fastboot.
-Get in to recovery mode.These kernels have full CWM.Press volume down few times when you see kernel logo.
-Wipe everything.Wipe data/Factory Reset.Format data, system and cache.Wipe dalvik cache and battery stats.
-Flash SJB 6.0.Your phone is Neo V.So no need patch.
-Flash gapps.
-If you kernel have modules (Like fusion), you need to flash modules too.Flash it.But few kernel modules built in (Like lupus).
-And it is done.
First boot may be longer , so just wait.Don't touch battery :angel:

My problem is, that I'm not able to flash the latest firmware with flashtool, because I get an error (see my first post).
As I posted some minutes ago, all drivers seem to be installed correctly, but when I try to install the drivers provided by flashtool I get some other error by Windows Device Manager which say that four drivers (three Sony Ericsson, one Google) could not be installed correctly. Don't know why

I solved your problem.Okay disconnect your phone and check;
enable "USB DEBUGGING" from Menu -> Settings -> Applications -> Development
enable "UNKNOWN SOURCES" from Menu -> Settings -> Applications
set Connectivity mode to MSC from Menu -> Sony Ericsson -> Connectivity -> USB Connection Mode
I think you forget to enable USB Debugging :victory:
Hit thanks if I helped you.

I'm very happy that you're trying to help me, but please read my other posts as carefully as I have to read the instructions of how to flash Roms on other phones then my Desire S
I stuck in a bootloop, that's why I try to flash stock firmware. So there is no possibility to enable USB-Debugging. But I think adb is not need in flashmode anyway, is it?

But this is weird as I already installed all drivers in \Flashtool\drivers\Flashtool-drivers
Thanks so much for the help!.

Ok found the problem. Was missing this first step:
enable "USB DEBUGGING" from Menu -> Settings -> Applications -> Development
enable "UNKNOWN SOURCES" from Menu -> Settings -> Applications
set Connectivity mode to MSC from Menu -> Sony Ericsson -> Connectivity -> USB Connection Mode
Added the other two steps so can be helpful for anyone else having issues, make sure all of above is set prior to trying this tool to root the phone.
Thanks so much for the help!

True :silly: . Hmm I can't understand.Two thing left.
1-)Can you tell me which drivers you installed?
2-)Do you have PC Companion installed? Or any other program use ADB.exe.Close PC Companion.Check ADB.exe.If it is working, close it.Then open flashtool.Try again.

No other program uses ADB, only opened programs are Flashtool, Chrome and WMP, no ADB related programs running in background

I solved the goddamn problem :victory:
Just used my PC with Win 7 instead of my Win 8 Notebook. But don't know if the OS was the problem or the flashtool drivers I successfully installed on Win 7. Anyway, problem solved, next try flashing SJB
