[Q] Need help in restoring the device to Kitkat from lollipop - Xperia Z3 Q&A, Help & Troubleshooting

Hello All,
I want to restore my xperia z3 D6603 back to its factory settings.
I received the device with Telekom.DE xxx.5.77 ftf
then i flashed the device with D6603_23.1.A.0.690_Customized_US.ftf without root or unlocking the bootloader.
Now i want to load the Telekom.DE xxx.5.77 ftf back and set it to factory settings .
Please help me with the steps.
Thanks & Regards,
Kishore Kumar.

Use Xperifirm to download the desired firmware.
Then build ftf file with Flashtool and flash the resulting ftf file via Flashtool.
Note that downgrade from lollipop to kitkat will need to wipe everything on your device.

Repairing Xperia J With PCC

Hi Friends,
I wanted to have my Xperia J with ICS 11.0.A.7.5 firmware to be backed up. So following some post here on this forum stating that first repair phone using PCC and then go to db\13740270\blob_fs and copy 3 files with name "File....." and then convert the file to ftf using Flashtool.
So I first repair it using PCC. It succesfully repaired but after repairing, I found that now it is not ICS 11.0.A.7.5 but its JB11.2.A.0.31.
Also instead of 3 files with name starting with "File..." in db\13740270\blob_fs folder, there are 4 files starting with that name.
Can someone please guide me out of these 4 files, which files are to be selected in Flashtool for creating .ftf file to keep the backup of 11.2.A.0.31 firmware?
Also we know that there are some bugs in JB 11.2.A.0.31 as well as its hard to root this version. So if I want to go back to ICS 11.0.A.7.5, how can i revert back.
Thanks very much.

Regarding the backup I'm not sure exactly but from what I understand you want to save the .31 firmware for future flashing. If so, if the .31 firmware is unbranded you won't need to save it because there are links to the .31 Central European version ftf file on these forums.
And regarding the getting back part, if you ever wanna go back to ICS you can just flash the ICS .ftf file ( again you can find the links in the threads here) and you're done. BTW, if you wanna update to .31 I would recommend rooting the ICS and then updating OTA so that you can keep your root.

Thanks Sir for your guidance.
I did it this way...
Previously it was ICS unbranded and I rooted it sucessfully. Then I Repaired it with PCC (for getting backup of ICS) but it was repaired with JB .31 and root was lost.
Should I follow this way ?
First Flash ICS 7.5 .ftf file, then root it, then OTA update with JB. I also want to know that :
1. Will instead OTA updating with PCC work?
2.Is there any way to get back ICS by flashing with PCC instead of flash tools?
Thanks

Not a problem man.
To answer your questions :
1- If you update withe Pc companion you will loose your root. Only updating over the air will keep the root. ( after you finish the updating process you simply need to update the superuser app from the playstore).
2- Unfortunately, if you use the repair function Pc Companion will give you the latest version available, there is no way of choosing which Android Version to install, it will choose it for you. So if you want ICS you need to flash the .ftf file with flashtools

[Q] Flashing Stock ROM on Sony Xperia L - C2105

I have Sony Xperia L - Jellybean 4.2.2 - 15.3.A.1.17 - Rooted Stock ROM - Locked Bootloader
For some reasons I have to make a hard factory reset with Sony Update Service program, but instead of letting the program re-download the firmware then installing it on the phone, I already made the FTF file that I downloaded in the past by using the Flashtool.
Now The Question Is:
Have I worry about losing the DRM Keys when I flash this FTF with the Flashtool ?, or this kind of flashing will not affect it ?, or I have to check Exclude TA in the Flashtool ?
Hey , anyone please help me

You dont need to unlock your bootloader,just find a ftf and flash it with flashtool...there are many guides on the internet
Thanks for the info, can you provide me a link where I can find official Sony ftf files?
How secure is to use random ftf file from the internet? I use online banking on my phone, so I want to be sure that is secure.

There are no "official" ftf's...You can make one by using xperifirm (i doubt the kitkat files are still in the servers)
ftf in xda are trustworthy most of the time
Thanks, can you or someone else send me the theme where I can download the ftf file for my Xperia from xda?
Don't think there is any KK ftf's left on expirifirm Sony usually remove them pretty quickly. There's bound to be one on here somewhere. I think I've still got a pre-rooted KK zip somewhere for the D2303 lte, also I don't know who told you that you need to unlock your Bootloader to downgrade/use flashtool, you don't it'll work on totally stock unrooted devices. You must however wipe user data+cache+appslog when downgrading from lollipop to KK and when Updating from KK to lollipop via flashtool.

Flashing your phone using Flashtool will solve eveything.
Get the required ftf (download from the ftf post or create your own). Use the FSC when prompted.
This flashing here have nothing to do with TA.
