[Q] Problems Downgrading to 4.1.2 - Xperia SP Q&A, Help & Troubleshooting

Following a number of guides I decided to downgrade to 4.1.2. I backed everything up using PC Companion and flashed the genereic uk 4.1.2 firmware.
when i tried restoring my backup only the photos appeared to restore. I decided to try a factory reset to see if that helped - no joy. I used the sony update service tool and it installed 4.1.2. but still no joy with the restore.
If i type in and call someone that would have been in my contacts list, their name does appear on the call log, so its almost as though the contacts are on my phone, just not in my contacts list.
Also now that I've rolled back to 4.1.2, both my phone and PC Companion recognise this as the most recent update. Does this mean when the 4.3 update comes out, i will have to wait for someone to post the firmware and flash it via flashtool rather than update via pc companion?
Thanks!

The backup you made will only work on android 4.3, root android 4.1 and flash android 4.3 ftf for keeping root, then restore your backup and create a new one using titanium backup(make sure you change the destination folder to a folder in your sd because flashing will format your internal memory) then flash android 4.1, root it and restore the titanium backup

Ah makes sense.
Thanks for the reply. Have you seen anywhere for 4.3 generic uk?
I can only find generic global.

[Q] android update

hi,
I own a Samsung Galaxy S I9000,
I never updated the system.
my Firmware version is 2.2
I was told that when you update the system it erases all the info on the phone, is it true?
I would like to know what is the latest firmware version for SGS and how do I update the phone. I believe there is already a page with instructions but I couldn't find the right one for me.
Thanks

1. If you update via OTA i.e. Update center, you will retain everything and system will be updated.
But if you flash the. 67 ftf you can still uncheck wipe data, app etc. to keep your data.
2. Without root you can use PC companion or backup app from sony... But 4.1 backups won't work on 4.2 but surprisingly 4.2 backups work on 4.1 too (it worked for.me when I flashed 4.1)
I think an app called "helium" can backup without root but I haven't tested it.
Your best bet will be to root and use Titanium Backup.
3. Savinh your Rom stuff can only be done via CWM recovery which can be installed after root. However you can make backup by sony's app and flash old ftf to rollback.
4. Haven't used the pc companion backup but the backup and restore app works perfectly. You can save the backup externally by copying the. semc-fullbackup folder from your chosen location of backup.

[Q] XPERIA SP C5303 Still stuck on 12.0.A.1.211

I bought a unbranded XPERIA SP two months ago and I am still stuck on Android 4.1.2 and the phone has the build number 12.0.A.1.211
Using the OTA and desktop update I keep on getting that my phone is up to date.
I looked up the customization number with *#*#7378423#*#* > 'Service info' > 'Software info' > 'Customization Version') and it is 1273-0043_R2A
Using XperiaUpdateChecker.exe and Google I cannot find anything about the customization number.
Based on advice from some users I rootded the phone and changed the Customization Version and still did not get the update.
How do I upgrade to the latest Android 4.3 version?

Thank you. This was helpful. I am now using the latest firmware and Android 4.3.
Unfortunatly I made a backup using Sony PC Companion and it does no longer allow me to restore all my files. So I have lost everything except pictures and the things Google saves, like contacts.!
For anyone reading this and want to update. Please do not use Sony PCC as a backup tool! Find some other way.

I had exactly the same problem. I used this guide to retrieve my data from the PCC backup:

The procedure is quite tedious, because you have to basically extract one app at a time from the backup. But it works.

[Q] Firmware Backup via PC Companion

I've posted this in the support forums over at Sony but am not sure how often they are visited so I thought I would repost it here.
Just purchased the C6906 and notice that the firmware it arrived with is 14.4.A.0.108 (Android 4.4.4).
I've installed PC Companion and both the app and the phone have notified me of an available update. The phone itself is reporting the update to be 14.4.A.0.108 (approx. 2mb's in size) which makes no sense to me since it's already installed on the phone. PC Companion has identified and apparently downloaded the available update as 14.5.A.0.242 (Android 5.0.2).
I've noted that there are a series of steps that PC Companion performs as part of the update procedure. I cancelled the procedure prior to the start of the third step which appears to be the actual flashing of the firmware because I wanted to check the forums here and at XDA for opinions of its stability.
Feelings on the new firmware tend to be mixed overall and that has caused me some concern, and I've yet to find the C6906 variant of the firmware the phone currently has installed (14.4.A.0.108) in the event I want to rollback. The fact that this particular firmware is reportedly easy to root appeals to me since I root all of my android devices.
My question is this: I've done the research and found that PC Companion backs up firmware before updating the phone, placing the necessary files in a folder labelled "blob_fs". But what isn't spelled out is whether this folder contains a copy of the device's existing 14.4.A.0.108 firmware or a copy of the newly downloaded 14.5.A.0.242 firmware which I cannot seem to locate on my computer. Does PC Companion push it to the phone at some point during the procedure? If so would a factory reset or a repair done thru PC Companion eliminate the update file from the phone? Or would either of the aforementioned options merely wipe the phone and then install the new update?

The only way you will get OTA to work via PC Companion is buy putting your phone back to stock (no root, no recovery). It might be possible to use flashtool to restore a stock build without wiping data, but if it goes into a bootloop, then you will have to wipe it to fix it, loosing everything.
You could use Titanium backup to save all your apps/settings onto the SD card, then force PC Companion to 'repair' your phone. But then you'll be stuck with trying to root your MM build so you can restore your TA backup (Don't be tempted by Kingroot).
Have you considered moving to an MM custom rom? Slim works with a locked bootloader and is very popular, or an MM stock prerooted build. Both of these have install instructions that recomend a wipe, but it may not be necessary.
Several users in the Slim thread have said they successfully flashed without wipe.
There are still lots of glitches and problems with the MM build, are you sure you want to go through the pain of being an early adopter? Another month or so and they'll all be fixed.
Make sure you do a TWRP backup before you start, preferably onto the SD card.

Does the custom roms unlock the bootloader?

No, neither does using a stock prerooted.
Generally, is it says 'stock' or 'LB' in the title of the thread, then you can use it without having to mess with the bootloader.
