[Q] Problems Downgrading to 4.1.2

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.

Upgrade firmware without losing current apps + data

Hi,
Currently i'm running in 5.0.2.
Is there any way/possibilities to upgrade my firmware to 5.1.1 or the latest firmware without losing any of my apps + data (include messaging, etc). I only knew the way is to backup all my apps using titanium but i'm afraid when restore back it will cause some error due to the new 5.1.1 environment. Need some advice. Thank you.

if you can do what you have to do is if you do it by flashtool you should not tick the option, apps and user log data and if you do not do the same recovery from wipes just install the rom.

Thank you. Will try as your adviced.

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.

How to Update an rooted device with Stock Rom?

Hey everyone,
i would like to root my P10 with Magisk and stock firmware before i can´t get any bootloader unlock key from Huawei anymore.
My question is is it possible to update the system to the latest Firmware Versions from Huawei (via FF or TWRP) later on without to re root the device ?
Regards.

Use my guide:
https://forum.xda-developers.com/p10/how-to/guide-manual-updgrade-to-update-oreo-t3758286
It does exactly what you want, but you still need to reinstall Magisk-Root because /system will be overwritten.
Personal data, settings and apps will be untouched by the update but do a backup just to be sure.

Bought 2nd-hand XZ1C, update fail over and over

hi everyone,
i bought a 2nd-hand xz1c and it's been great but it had a custom rom installed and was rooted then reflashed with stock rom when i got it, that's what the seller said anyway but i can't get in touch with him anymore.
i haven't been able to update anything since i got it. the system downloads and fails to install the update over and over. i have no idea how to unroot the phone if that's possible or what programs to use to do it, is there a guide where i can just get it to stop downloading and trying to download the newer firmware? ideally i'd like to install the update, failing that just to get it to stop trying would be "ok"... probably not from a security point of view though.
i'm a complete noob sorry. ly

As the phone was rooted, the bootloader is unlocked and the OTA update will fail. It's impossible to relock the bootloader, so you'll have to manually flash the updates.
You can use a tool called xperifirm to download new firmware version and newflasher to flash them. Search the forum for guides.
To stop the updater from tryung, go to settings/apps, check show system apps, find the app called Software update and force stop it. It will restart on phone boot, so you'll have to close it again once in a while.
You can also use ADB to disable the updater for good - again, search the forum for a more specific guide...

If you really feel there is some sort of advantage to having the latest firmware on your phone, then upgrade it yourself, you won't damage the phone or change your warranty status.
Look on Xperiafirm and find a 47.2.A.10.62 customised build - CE1 would be a good option
Download Newflasher and put it in the same folder as the firmware you downloaded from Xperiafirm
Delete Userdataxxx.sin and files ending in .ta (but not in the boot folder) . This will ensure that you don't lose any personal data. Also delete persist*.sin to avoid losing android attest key.
Then start newflasher.exe and follow instrctions.
You might need a copy of the Sony driver
I would make a backup with Xperia transfer before you do anything, if the phone is glitchty after your rebuild, then factory reset it and then restore from the backup.
You'd probably need to read up on janjan's kernel fix to get you working without a green camera.
You'll also need TWRP
