Hi all,
I have a rooted Z3 with dual recovery and locked bootloader running firmware 23.1.A.0.690.
Since the OTA to firmware 23.1.A.1.28 is minor, I was wondering if it is possible to flash an update zip file while keeping root and modified recovery.
any idea ?
thanks

Modified bootloader? Do you mean unlocked? If so then you cannot do OTA, is says so explicitly on the Sony site about unlocked bootloaders. But you can make a backup in recovery, flash a stock FTF of that version (System only) then just flash back your custom kernel (Before booting the phone) and restore data from a backup
If you mean locked bootloader then you can OTA, if its a small update then the chances are it wont format system so you will keep root, but if its a large file the chances are it will format system then re-install it so you will lose root.
Just flash a pre-rooted version of the updated ROM in recovery
Sorry, i meant keeping root and modified recovery (not bootloader).
My bootloader is locked indeed and i am on stock kernel.
So, to your point, i should be safe upgrading minor OTAs?
If so can I anticipate sony's rollout of the OTA and flash the update zip? And where can it be found?
Thx

Maybe.... it all depends on whether or not the OTA formats system and reinstalls it. If it a minor update they may not do that so root and recovery (Which is in system for locked bootloaders) are not deleted.
Its a gamble...
to be 100% safe, you will need to get a prerooted flashable zip and flash it
Hmmm... Ok, but upgrading with a prerooted zip involves flashing a full rom not just the update right?
I am ok with that but would rather save the hassle.
Thanks for the advise
Hi,
Happy to report back that OTA process went smooth.
I am now running 23.1.A.1.28 and still have full root & dual recovery!

Benjieb,
Sorry friend but it was not clear to me... you updated via OTA and keep the root?
Yes that's right. I fixed the typo in my last post.

How do you do it? I mean,you were stock .690 berofe ota?you delete anything of stocks apps??because i test to do the ota update but at the end of processus it's says "verrification impossible" and i saw somewhere that's if we touch or delete stock apps we can't ota ....ans if possible,nobody van do a flashable ZIP with just ota update????
I was stock indeed, and you are right playing with system apps probably prevent OTAs.
That's why I deactivate system apps rather then delete them.
I guess you will have to do a full rom flash.
I'm on stock ROM rooted. Updated to. 28 via OTA just only. Root access still available!!

If I root the latest stock 4.4.2, will I still be able to get future OTA Updates without braking the root or custom recovery, well if root gets lost I can always root it again. Just asking, maybe I won't be able to get OTA Updates at all after rooting but I don't know so that's why I'm asking it here.

The OTA will download but not install. You need stock recovery AND any system file that is updated by the OTA needs to be stock as well otherwise OTA install will fail.
Plenty of threads on XDA speak of this.
If you look at the OTA updater file you will see if uses MD5 (or similar) to check each system file it updates to make sure its as it was originally.
When you root it alters some system files.
Best thing is to install custom recovery and take a backup before rooted. Then root. When you get an OTA just restore backup and flash stock recovery. Then OTA will re-download. Let it install, then flash custom recovery and re-root.
Thanks, well I'll just stay unrooted and make the best out of it, the Moto G is just as amazing as Motorola developed it to be.
No stock recovery it's no need. I updated last ota with Philz recovery without problems.

Do you mean you downloaded OTA and flashed manually via recovery. You can do that I agree, but what you can't do is let OTA install naturally the way Motorola intended.
No. I had Philz recovery. System stock partition. Downloaded ota normally, reboot like ota update ask, phone reboots in philz recovery and this last flash ota automatically without any problem. There is not need to reflash stock recovery or flash ota update manually with custom rec, only need a non root stock system partition. I dont know if stock cwm or other rec like twrp work in same way but i doubt, always used only philz recovery.
You do not need stock recovery, I don't know who made this stupid rumour up. I use twrp and it flashes fine.

Hello Guys.. since I'm a nexus 4 user before...not familiar with this new phone want to ask if using Giefroot and successfully root my phone Can I still do a system update specially when lollipop comes..without any issues? my rooting purpose: just want to install root apps like titanium back up to uninstall bloatwares, greenify without xposed installer...
You will be notified by update center when Lollipop update is available even if your device is rooted or not, but not sure about if you will be able to install the system update or not.
I had seen some rooted devices could download the OTA but failed to install the update.
But there's nothing to worry since you can always flash the ftf file via flashtool, without wiping any of your data..

I can install any ftf.file right as long as it is for my device..also when ota is available the ftf. File is also release right?

Yes, someone will make and upload an FTF.
In an extreme circumstance it may need Flashtool to be updated, but Androxyde will do that and push another version.
In the meantime, you can always relock your bootloader and use PCComapnion to update officially, then unlock the boot again
You can also use Xperiafirm to dowload the ftf files.

Doesn't the root process require downgrading though? So it'd make updating through PCCompanion redundant.

Not really, if you have an unlocked bootloader you can relock, upgrade, unlock, flash an insecure kernel**, flash SuperSU and you are done. no need to downgrade, that's a locked bootloader method.
**Someone will upload an advanced stock kernel within minutes of it hitting our devices, its not much of a tweak to make it insecure
(Just changing a 1 to a 0 in the right place)
Hell, they may even throw in recovery in a couple of minutes as well....
Yes but I was replying in the context of the OP who said 'using giefroot' so I assume it's the locked bootloader method he is asking about.
So I have an xperia update alert. Is there a way to update to the latest and retain my files as well as root access?
No. If you are on KitKat flash a pre-rooted Lollipop.
If you upgrade you can root only if you unlock the bootloader. It is the only way to root Lollipop directly.
There is no sense to upgrade, then downgrade to root. Do that now, since you are on KK.
In short : Do not upgrade officially, upgrade by flashing a pre-rooted Lollipop. You can do that even with an locked bootloader with Flashtool. Find an appropiate ftf.

I'm not on KK, Im on lollipop but I believe there's a newer version to LP for the Z3. I'm on 23.1.A.0.690
What size is it? Maybe it's not a firmware update.
It's an Xperia system update I can't pull up details about it without beginning the install process
you would have to flash a pre-rooted flashable rom to retain root, ota updates generally tend to kill root

Thanks, I've been a little out of the game when it comes to flashing and rooting. I rooted my phone about a week ago and put lollipop on it. I assumed it would be the case that i'd have to flash the updated version I just wondered about retaining my files because i've gone through a bit of trouble debloating and tweaking the phone.
you'll most likely have to go thru that process again of debloating depending on what rom you install as it will most likely put most of the stuff you have removed back into the system

I suppose I don't mind debating again but what can I use to make a backup of my apps and app data? to then restore once updated... are there any full proof tools?

I'm on the XT1540 and I got my OTA notification and went back to stock recovery (still rooted and unlocked bootloader) but it fails halfway through flashing everytime. I reflashed TWRP and captured the OTA into a zip but get an error about updating binary or something when flashing it. Is there something I need to delete from the OTA zip to allow it to flash in twrp?
Sent from my MotoG3 using xda premium
You cannot update your systems software using the OTA update if you are rooted and have modified the system in any way as there are checks of original system during the auto update over the OTA. This means having the original recovery too. Wont work on TWRP or CWM. So no root and no custom recovery for OTA. Unlocked bootloader is okay.
In case you want to try the OTA update then what I have noticed on my XT1550 dual sim APAC version is that even unrooting it using the SuperSu unroot option is not going to help. In my case I could download the OTA and waited till it replaced the system software but got stuck midway of the boot animation.
I had to flash the 23.72-33 version of the stock ROM and opt for the OTA update. This time though I was successful.
Hope this info helps.
Yes, what arunhebbare says. you need to back up al your data and restore your stock firmware and than update via ota.
that is the best way of doing it

This...do a full factory image restore, then adb sideload the ota file. It's signed. TWRP can't install it.
Just use fastboot to flash the factory image for the version you want ... screw wiping your user partition like the above recommends.

This...I can't understand, for the life of me, why everyone is wiping userdata with fastboot....that wipes your android data, and internal storage in one shot. Cache erasing is another totally unnecessary step. All that's necessary, at the most, is a factory reset with TWRP to wipe the android data and both caches....but even that shouldn't technically be necessary for an update like this. It's not like this is the marshmallow update!!

@arunhebbare I've got the APAC version of the G3 as well, which ROMs are you flashing? I could only find images of the India version, did you use those?
I'm using a rooted HTC U11 with the latest TWRP and Magisk. Since yesterday I get a message that tells me to upgrade my HTC U11 to version 1.27.401.5. I can't install the downloaded ota so I need a complete rom. Where can I find that?
Maybe next door
Too much info error... So it's possible to flash an OTA over my rooted stock rom using TWRP?
Since the OTA is already downloaded to /data/data/com.htc.updater/files can I just copy it to the root folder and then flash it with TWRP?

No, TWRP cannot handle an OTA completely. You have to reflash stock recovery.
And even if you reflash stock recovery the OTA could fail to apply.
Have you modified your system partition after rooting? Any mods that install to system instead of data?
If you have modified the system partition the OTA won't apply. You have to reset to stock, i.e. by using an RUU

I'm still on the stock rom with TWRP as recovery. Afaik I didn't use any mods that install to system instead of data.
I just want to install the current version 1.27.401.5. If that's not possible by OTA then a full rom would also be welcome.

Then you might get the OTA applied by
reflashing stock recovery
