[GUIDE] Download ANY firmware customization from Sony & create an FTF with Flashtool

Part A: changing your customization number to download a different firmware customization (optional)

Requirements:

• Rooted Xperia smartphone with locked bootloader:
  - For firmware versions 10.1.A.1.350 and 10.1.A.1.434, use goroh_kun root exploit
  - For firmware versions 10.1.1.A.253, 10.1.1.A.307 and 10.3.A.0.423, use perf_event root exploit and remount-reboot fix
• Build Prop Editor
• The customization number of the firmware you want to download (see list, only customizations for the same phone model)

1. Start BuildProp Editor.
2. When a Superuser request pops up, tap 'Grant' or 'Allow'.
   
   
   
   
   
   
3. At the first start, a backup of 'build.prop' will be created automatically, which can be restored in case of any problems.
   
   
   
   
   
   
4. Scroll down to 'ro.semc.version.cust' and tap it.
   
   
   
   
   
   
5. Change the value to the customization number of the firmware you want to download.
   
   
   
   
   
   
6. When asked to reboot, tap 'No'.
   
   
   
   
   
   
7. Tap 'ro.semc.version.cus_revision' and change the value to 'R1A'.
   
   
   
   
   
   
8. When asked to reboot, tap 'Yes'.

Part B: downloading firmware with Sony PC Companion

Requirements:

• Sony PC Companion
• Xperia smartphone with locked bootloader

1. Delete this folder if it already exists:
   - Windows XP: C:\Documents and Settings\All Users\Application Data\Sony Mobile\Update Engine\db
   - Windows Vista/7/8: C:\ProgramData\Sony Mobile\Update Engine\db
2. Start Sony PC Companion.

• Case A: new software version available
  
  
  
  
  
  
  
  

  1. Click 'Update'.
     
     
  2. Click 'Accept'.
     
     
     
     
     
     
  3. If you only want to download the firmware without updating, disconnect your phone as soon as the "Downloading software..." screen appears.
     
     
     
     
     
     
  4. If you disconnected your phone, this window will appear, which you may close. Otherwise your phone software will be updated.
     
     
     
• Case B: no new software version available
  
  
  
  
  
  
  
  

  1. Click 'Your Phone / Tablet is up to date'.
     
     
  2. Click 'repair my phone / tablet'.
     
     
     
     
     
     
  3. Click 'Next'.
     
     
     
     
     
     
  4. Repairing your phone will delete your personal data and settings. If you don't want this, see step 6. Click 'Continue'.
     
     
     
     
     
     
  5. Tick the checkbox and click 'Next'.
     
     
     
     
     
     
  6. If you only want to download the firmware without repairing, disconnect your phone as soon as the "Downloading software..." screen appears.
     
     
     
     
     
     
  7. If you disconnected your phone, this window will appear, which you may close. Otherwise your phone software will be repaired and your personal data will be lost.
     
     
     

Part C: creating an FTF file with Flashtool

Requirements:

• Flashtool
• Firmware files from Sony PC Companion or Sony Update Service (see part B).

1. Start Flashtool or Flashtool64 (for 64-bit Windows).
   
2. Click 'Tools' > 'SEUS Decrypt'.
   
   
   
   
   
   
3. Select the 'Source Folder' (copy-pasting this path will not work):
   - Sony PC Companion (Windows XP): C:\Documents and Settings\All Users\Application Data\Sony Mobile\Update Engine\db\13740270\blob_fs
   - Sony PC Companion (Windows Vista/7/8): C:\ProgramData\Sony Mobile\Update Engine\db\13740270\blob_fs
   - Sony Update Service (32-bit Windows): C:\Program Files\Sony Mobile\Update Service\db\13740270\blob_fs
   - Sony Update Service (64-bit Windows): C:\Program Files (x86)\Sony Mobile\Update Service\db\13740270\blob_fs
   Move all 'Available files' to 'Files to convert' by selecting them and clicking the right arrow button.
   Click 'Convert'.
   
   
   
   
   
   
   
   
   
4. Enter the following details:
   - Device: your phone model, e.g. 'C6602', 'C6603', 'C6606' or 'C6616' for Xperia Z (see 'Settings' > 'About phone' > 'Model number').
   - Branding: can be found in the first columns of these tables by looking up the customization number, e.g. 'Customized US'.
   - Version: the build number of the firmware, e.g. '10.1.1.A.1.307'.
   Move all files from 'folder list' to 'Firmware content' except *.ta files (e.g. simlock.ta, preset1.ta, cust-reset.ta, ...) by selecting them and clicking the right arrow button.
   Click 'Create'.
   
   
   
   
   
   
5. When you see 'Bundle creation finished', your FTF will be in 'C:\Flashtool\firmwares'. If your combination of device/branding/build is not yet available on xda-developers forum, please be so kind to share it (see part D).
   
   
   
   
   
   
6. To save about 2 GB of disk space, delete this folder:
   - Sony PC Companion (Windows XP): C:\Documents and Settings\All Users\Application Data\Sony Mobile\Update Engine\db\13740270\blob_fs
   - Sony PC Companion (Windows Vista/7/8): C:\ProgramData\Sony Mobile\Update Engine\db\13740270\blob_fs
   - Sony Update Service (32-bit Windows): C:\Program Files\Sony Mobile\Update Service\db\13740270\blob_fs
   - Sony Update Service (64-bit Windows): C:\Program Files (x86)\Sony Mobile\Update Service\db\13740270\blob_fs

Part D: sharing your FTF on xda-developers forum

1. Upload your FTF to a file host. I use Dev-Host for this purpose, but it only supports files up to 512 MB, so I use WinRAR to pack my FTF with the following options: 'Compression method' = 'store' (since FTF is already compressed), 'Split to volumes, size' = '512 MB'. Of course you can use a different file host and archiver if required. Please note that Google Drive, Dropbox and Box all have bandwidth quotas, so your shared files may be disabled if they are downloaded too much.
2. Create a new thread on xda-developers forum in 'Xperia Z General' and include at least the following information:
   - Device
   - Build number
   - Android version
   - Customization version
   - Region
   - Branding
   - Download links
   Here is an example: [STOCK ROM][FTF] Xperia Z (C6603) 10.1.1.A.1.253 Generic BE (Unbranded/Belgium)

Is a locked bootloader really necessary for step A?

Is a locked bootloader really necessary for step A?

Not really for part A, but it is required for part B (because Sony Update Service will only work with a locked bootloader) and part A is useless without part B
However, if your bootloader is unlocked, you can use "Flash tool for Xperia™ devices" (Sony Emma).

even after restoring a TA-Backup? sorry, I'm still new to the way sony handles this...

After restoring your TA-Backup (or doing a relock with Flashtool) and flashing a stock ROM, you can use Sony Update Service again.

[*]If you just want to download the firmware without flashing it to your phone: watch the download progress very closely. When the end is near, start holding the USB connector. As soon as the download is completed (see screenshot), IMMEDIATELY DISCONNECT YOUR PHONE. Timing is crucial here. If you disconnect it before downloading is finished, the download will stop. If you disconnect it too late, you might lose data. I used this method several times without losing any data. My experience is that the download progress bar suddenly goes to 100%, before you would expect it, so be prepared!

Thank you for your guide.

I just want to add that with "PC companion", I disconnected my phone before the end of the downloading and it didn't stop. I make my own .253 FTF without problem.
Somebody could confirm ?

You're right!
When restoring with PC Companion, you can disconnect your phone during the download.
The downloaded files will be in 'C:\ProgramData\Sony Ericsson\Update Engine\db\13740270\blob_fs'.
The only thing I'm not sure of, is if PC Companion also downloads the full image when updating?
I will download my next update with PC Companion. If the files are the same as with Sony Update Service, then I will update this guide.

What I can tell you is that I made my 253.ftf and 253.zip from an updating PC companion process between .434 to .253. But I didn't compare if the files are the same as with SUS. I use flashtool to flash the ftf and TWRP to recovery flash the zip and didn't have problem...

As soon as the .307 will be available here in France, I will try to reproduce the same process and let you know

Changing build.prop not worked for me
Sony update service downloads same customization version - before change file.(phone restarted after change)

Are you sure you changed the right value? There are multiple entries with your customization number in build.prop, but it's (only) this one you should change: 'ro.semc.version.cust='. After changing this value, save and close build.prop and open it again to check if it has been saved correctly. Also, did you delete the folder 'C:\Program Files (x86)\Sony Mobile\Update Service\db' before starting Sony Update Service?

Yes i am sure. "ro.semc.version.cust" was 1270-7689 (generic UK), and i changed it to 1271-5145 (generic Turkey). And i duble check the value after save it, delete db folder.

That's very strange. I successfully downloaded three other customizations by using this method. A guy who PM'd me was also able to change from 'Generic UK' to 'Vodafone UK' by following this guide. Are you sure SUS was downloading 'Generic UK' again?

I think you need to change also the id for ro.product.name=
And ro.semc.version.cus_revision=

That what i did to make it work.

I didn't have to change those values, but something just came to my mind: I had ro.semc.version.cus_revision=R3A and I downloaded firmwares with R4A, R6A and R11A (all higher).
The guy who changed from 'Generic UK' to 'Vodafone (UK)', changed from R14A to R16A (also higher), but he said he first tried to change to 'Generic ES', which is R5A (lower), and it didn't work.
When I check the latest firmware versions with the URL you can find here (see browser bookmark), I get an empty response if the 'cdfVer=' in the URL is higher than the one of that customization, so I always use cdfVer=R1A there.
This will probably also do the trick here!
@relicks, could you try to change your values to this (without changing anything else):
ro.semc.version.cust=1271-5145
ro.semc.version.cus_revision=R1A
and see if that works? I think it will

nope
It says Your phone has already latest firmware.

 

[Apollo89]

nope

Does Sony Update Service still offer the option to do a factory reset? I have had this problem where factory reset wasn't even available anymore.
I had to restore the original build.prop from my backup, then I rebooted and SUS gave the factory reset option again.
After that, I modified build.prop again, rebooted and then it worked.

If that still doesn't work, you can try this:
ro.semc.version.cust=1271-5145
ro.semc.version.cus_revision=R7A

Don't forget to do a full reboot each time you change something in build.prop and delete the SUS db folder.

Close pc companion and use update service.

What did the trick? You just tried again with 'R1A'? Or did you use 'R7A'?
No, unfortunately it is not possible to download previous firmware versions from Sony. You can only downgrade if you can find the right FTF file online.
