[Q] downgrade xperia j from jb to ics? - Sony Xperia Miro, Tipo (Dual), J, E

Hello Guys.
my sister has got a xperia j. I updated it to jelly bean.
But now i see that rooting isnt possible without bootloader unlock.
So the question i would like to ask is:
it possible to downgrade the xperia j via flashtool to ics or will it brick?
Second thing. I would like to install cwm on it (there is a version for locked bootloaders) and flash paranoid rom.
Do i have to unlock the bootloader after this or can i just flash the rom with locked bootloader?
Thanks in advance

i never brick my phone through flashing ftf and kernels....so go to general section and find stock.ftf rom for your j....then download flashtool (google it), connect your phone to flashmode (i think it is vol - and connent to your pc), select stock.ftf file to flash and flash it....after that if all will be ok your phone will boot after 10-15 minutes so be patient... if you have errors during flashing just post the image flashtool or the logcat... paranoid rom is for unlocked bootloaders because has a custom kernel...if you want a rom, go to install gimlo, paradox, ultrabeast etc...

If your sister is using it then I would suggest flashing the jb firmware. Coz its sorta best when compared to older stock ROMs...
If u wanna use it for your own benefit then unlock the boot loader, download the xperia j(Jlo) CM 10 FXP from freexperia project site...
Download gapps.zip for CM10
copy both the files to sdcard
then flash CM 10 kernel and then power on repeatedly press volume buttons you will enter into CWM in that select install zip from sdcard flash the CM 10 FXP.zip file
Flash gapps.zip
Wipe cache
Wipe dalvic cache
reboot
Phew !

[Root] [CWM] Xperia J

Root and CWM for Xperia J Finally!
Thanks to srl3gx and Bin4ry for their awsome work!
and ME for taking risk!
Make sure u are in 11.0.A.3.28 or 11.0.A.3.18 firmware ALONE with Locked Bootloader..
This method Dosent Work on 11.0.A.7.5 Firmware! (working on it! )
for .28 firmware download from here and flash it
if u dont have a flash tool download it from here for windows and install drivers located in C:\Flashtool\drivers (choose all drivers)
since flash tool does not have xperia j drivers..u may hav flashing problem...for that
1.download and extract d ST26.zip ive uploaded
2.open flash tool
3.click devices>import
4.navigate to d file u've extracted
5.now xperia j driver is installed
u can now flash without problems
Now back to rooting...
Root first! thn apply CWM!
Steps for Rooting:
1.extract Root_J.zip
2.make sure 'usb debugging' is enabled in devolpment settings
3.double click Runme.bat file for windows users...runme.sh for linux users
4.wait for process to finish (mostly should work)
Steps for CWM:
1.extract CWM_J.zip
2.'usb debugging' on
3.double click 'install.bat' only for windows (linux not working! my bad..)
4.wait for it.....installed! close the shell program and switch off the phone..
Plug in charger or USB....the phone switches on....press up and down volume keys repeatedly when SONY logo flashes.....voila u get into CWM!
You need plugged in charger or USB to goto CWM! Else CWM wont Work!!
reboot to system and see if supersu is installed finish! ur phone is rooted and cwm is installed !!
CWM has little bugs ..but its a never mind stuff..
use arrow keys to navigate..power button to select and 'go back' option in cwm itself to go to previous options.
Comment if it worked for you...let others know!
Tested on my xperia J and Miro
Dont restore factory setting or else CWM will vanish...n u hav to reflash whole firmware again
for questions and problems ask srl3gx
HOPE I HELPED...hit thanks
Sorry for the last update! It Dindn't Work for many devices!
wow finally it arrived.
Anyone tried this already?

Followed your instructions on my Experia J. I have build 11.0.A.3.18 (UK on orange/EE). I decided against flashing to 3.28 and to try with 3.18, but to get the Flashtool working I did the following:
Once the ST26.zip file is extracted (using Winrar) I then have to open this extracted file again in WinRar to get the files that should live at C:\Flashtool\devices\ST26 (loader.sin etc.). I then had to copy the original file ST26.ftd to c:\Flashtool\devices. I enabled USB debugging in the Developer settings on the phone and Flashtool started working properly.
I was able to root and CWM the device as per your instructions on buiild 11.0.A.3.18. Cheers.
The major problem with this CWM method is that it's designed for the Tipo, so when you try to flash a zip made for jlo, it fails. I had to remove the assert from the top of the scrip to flash with this.
Thanks for trying on .18 firmware... I'll update d thread

Have you tried flashing a compiled ROM? It fails as the CWM thinks it's on a Tipo device.
Plus if you wipe your system partition, you lose CWM, it's not a good solution. I've posted a CWM as a boot.img in my CM10 thread

OK, plus this will work for people who cannot unlock their bootloader. But perhaps you should put a warning as some people may want to wipe their system partition before they restore a backup (which will work) but if they for what ever reason try to reboot the phone they will be lost and will have to restore via flashtool!
thanks for report...updatd
very good work thx!

I've updated my xperia j to firmware 11.0.A.7.5 and now i can't root it with this method...
Any help?
Yea im the same 11.0.A.7.5 cant you flash the phone with older firmware?
Okay i flashed that firmware from first page and now my phone is rooted thanks alot
If we can get ftf file of 11.0.A.7.5 firmware and flash it with Flashtool without wiping data (just wiping cache) maybe we don't loose root... but where can we found that ftf file???

X-Parts problem

It's not working when I boot my phone,pressing Vol button down or up,NOTHING!
When reboot with app,then works like charm.
Why can I not boot to CWM manualy?
I have Xperia mini official ICS 4.0.4 .
Do I have to unlock bootloader and flash it?
Well,that's how x parts works!
If you unlock bl,you won't need this.... You can install a custom kernel which has cwm pre installed and you can access manually
Sent from my MT11i using xda premium
But I don't want to install custom kernel.
I'm gonna try to flash the cwm with RecoverX.

have any idea where i can get CM9? CM10 doesn't really work well
There's no CM9 for Tipo/Miro/J and there will probably never be so.
CM10 is still in development phase.

Wipe data and cache etc before installing.
Sent from my LT18i using xda premium
Wiping app data from Applications menu also helps, if you have problems after updating.
As a rule of thumb - if anything Force Closes, wipe it's data, if it persists, wipe all the data using CWM.
use any other keyboard
same thing happened for me once and then i reflashed every thing was fine after that:good:

ok listen...can you flash stock.ftf rom to your tipo? just download flashtool (google it) and find stock.ftf from general section...one other way is to flash vergeance kernel with flashtool, enter cwm and flash a rom from android development (or cm10 from original android development) if you dont understand something tell me....
P.S. after you flashed stock rom or vergeance kernel turn on your phone and put charger to see if it charging

wtf this is the error i see when i try to flash the ftf file
it seems that you have wrong header.sin or you didn't enter the flashmode properly. make sure you get notice 'the device is plugged with flashmode' or something like that when you plug in the usb to your pc. to fix the header.sin issue you'll need the correct one. you can find it on the same thread where you got your tft.

i think that ico98 dont know how to fix header.sin and its better to flash a kernel from fastboot...its more easy...do you agree?

I'm not sure about that. he didn't give any specific info about how messed up his system is. if he install any stock ICS based rom (without any custom kernel) his problem mostly could be fixed by reflashing the rom and wipe the data. flashing a kernel won't fix this issue. aside from that scenario, there are several more scenario i.e:
1 he could have install a JB based rom then he install a ICS rom, completely dead. need to flash complete tft or reflash JB rom and wipe data.
2 ICS rom with custom ICS kernel. can be fixed by flash a stock kernel
3 etc etc...there are a lot of scenario
my main point is that flashing a kernel doesn't always fix anything. in most cases, I only suggest that step for more advanced user. without enough data about the system condition flashing a complete tft will be a general and always working method.
anyway, before we do any 'flash' thing, IMO wipe data might be a good choice. most new member forget about that important step and ended up with a bricked device.
ok then...i said to flash kernel and to choose a custom rom (gimlo, paradox etc) but if ico98 download again ftf file will he have this problem again? (header.sin)
P.S. sometimes i forgot to wipe system and data when i am to cm10 and i want to go back to ics and the only problem i have is some apps to force close....no brick only fc
P.S.2 i installed kernels from xperia mini pro and insecure kernel E dual and my phone didnt brick, just not boot...maybe my phone has immunity at brick ahahahahahahaha

well...it doesn't means that your system is immune. you're just lucky enough to never experienced a hardbrick.

[Q] Xperia Tipo Dual - Wont start after flash

I tried to flash my Tipo Dual with KangXperiaProject and after i flash it with clockwork its not starting.
When i plug the usb and press vol- the led turns to green and flashtool reads it in Flashmode (the same thing with vol+) but flashing with Flashtool stops at "Reading device information"
I relock the bootloader, i tried SEUS (No software for your phone) and PCC (No software available for your phone/tablet)
Any idea how to wake up my Xperia ?
you can first install the vengeance kernel..it has cwm inside it. once you're done flashing this kernel, you can flash stock based roms like Gimlo 2.0
all the best.
Try like flashing a custom boot.img like from cyanogenmod via fastboot..you will
Have recovery...
And then flash any Rom..
No software available means that,the bootloader is still unlocked..
