[Q] How to downgrade to Kitkat from Lollipop without losing any data? - Xperia Z1 Q&A, Help & Troubleshooting

I'm using locked rooted Kitkat,
updated via Sony PC Companion without wiping anything
after the updating to lollipop, it charges so slow, even when it's turned off
I used all the chargers here.
I'm planning to go back to kitkat without losing any app data.
I have no recovery and not rooted in lollipop. What can I do?

Backup your data using Titanium Backup or something app like that, and copy your backup OUT from your phone.
You can't downgrade WITHOUT wipe internal storage, because Sony implement encryption by default, as Google recommended it for used in Android 5.0.x
You can try downgrade without wipe internal data, if you don't believe what I say xD

I believe in you, But it's just hard to backup my data esp using titanium backup because im not rooted.

I think your only option is to wait for a Root method for Lollipop that does not require a downgrade first so you can use Titanium again. I tried to keep Data last night when I downgraded in prep for a rootable re-upgrade, and it froze during boot. Trying again while wiping the Data partition worked flawlessly.
Honestly, unless there's something stuck in there that you absolutely can't do without, your best bet would be to just take the loss and format the Data along with your downgrade.

I was eager to wait for the root without wiping data on lollipop.
But last night I solved my problem, I uninstalled Xposed and the apps from Xposed.
My phone is not discharging so fast now.

hello guys ,, dev.
i have problem with downgrading lollipop to kitkat on sony c3 d2505 it stop on flashing looder and there is no blue light on phone led .... please help what to do ??

[Q] Will firmware update loose my data & apps? no root cant backup apps

I have a new (2weeks) samsung GT-I9003 which kies report a new firmware update & before doing that want me to take backup but it will only backup my contacts/sms etc. how do I backup my installed apps as I have not yet rooted my phone, I searched the forums & found a way to root but got to know that even rooting will loose my apps/data so what should I do first?
I need the following things
I am testing various apps to find the best ones which I will using long term so as of now lot of install/uninstall hapening, after few days once I settle I want to update new firmware but should I root before that or after updating to new firmware.
Does rooting remains rooted after new FW updates in future?
Once rooted I can install apps like Titanium, unrooted I can't use Titanium yet to back up my apps & its data so its a catch 22 situation for me & atleast once I will have to loose my apps data but this time I should do it once for all so I can streamline future updates.
Hope some one can answer this.
If you update with kies you wont loose anything, if you update custom roms(for the first time) you will loose your apps and data.
Thats a good news for me, so should I 1st update the firmware via kies then root it as 2nd step?
I took backup & then started the firmware update, it downloaded a small file showed 100% complete & then strangely it opened another windows & its now downloading a huge file of 400-500Mb...........is the firmware that big?
The downloading is going on past 10 mins on 1mbps connection.
Finally it gave error in mid way I assume that something happened & made the usb connection loss, I got these screen shots & the phone is now hung displaying "downloading do not turn off the target"
What should I do, need help?
Since i did not get any answer i took the battery out & then plugged in again the phone booted fine.
I now have rooted my phone, if i update the firmware will I need to root it again?

depends on the firmware, most custom roms have root already build in

[Q] Phone freezes after OTA update 4.1.2

Hello there,
I just updated to 4.1.2 with mattlgroffs file 81.5.4002-91.2.26001.Retail.en.EU 4.0.4-4.1.2
Unfortunately the phone freezes quite unmotivated several times a day. The phone freezes with no user interaction or directly after pressing a button.
The following I tried without success:
Reeinstalling the ROM with deleted cache and data
Reeinstalling the ROM with and without applying the Titanium backup
I thought about downgrading to 4.0.4 again, but read that would brick my phone.
Does anyone experience a similar problem? Are there any solutions?
Thank you very much.
Any idea?
Regards
I suggest you to do a full data wype and re-install with RSD Lite. After the install, update via OTA.

So what are saying, tha even on jelly bean we can downgrade to ics??
Uh ... better not. I do not want to have my phone bricked.
What I noticed:
1. After full wipe and reinstalling mattlgroffs OTA rom without rooting I did not have any freeze for days
2. After rooting the freezing started every one and the other day
3. Today me rarz froze for the 5th time in 4 hours.
I suspect it has something to do with the rooting. I NEEED a rooted phone, though!
Is there any program to protocol which app/process caused the error?
Best regards.

[Q] Is it possible to root on 4.1 without losing data?

I was on 4.0.3 when I first rooted. After using the phone for sometime, I have accumulated some data that I'd rather not wipe or spend time meticulously backing up. Today, I successively upgraded to 4.1 without any issues besides (unsurprisingly) losing my root. Is it possible for me to root it on 4.1 without losing my data, and what would be the best way of doing so?

Just use this root method found on the FAQ's. Will give you root without messing with anything else...

Rooting will never erase your data.

[Q] Migration to Android 5.0

Hi,
I have a Motorola Moto G XT1068 - Dualsim, german version. I unlocked the bootloader and installed CWM PhilZ. OTA update does not work so I just skipped it until Android 5.0 is out now.
Questions:
1) I am using Titanium Backup Root for backing up my Apps, SMS, phone lists etc. I did not get any support from them if and how it will work on Android 5.0 due to the rumors that root is harder to enable. Any other update strategies, which programs do you use? ADB?
2) Which Rom (Fullrom?) do i have to flash in order to get Android 5.0 via OTA?
Thx for your answers
AFAIK no flashing of ROM is necessary as long as you're on stock. What you need is a stock recovery. I reckon you flash that ASAP.
Also, you might need to look into your system apps and make sure that you haven't deleted/disabled or converted to user apps.
Besides these steps, you'll be fine and will be able to update.

You have to install stock firmware and re-lock your bootloader. The guide to install stock firmware is on the general sub-forum and should be here.
I suggest using SMS Backup & Restore to backup your SMS. However, I recommend waiting until root is out to flash Android L. Then you can use Titanium Backup to restore your user apps & data.
I'm running L myself so I have to patiently wait for root. Good news though! The Moto X got a root solution by chainfire for Android L already. This means we could get root soon for Moto G.
Thank you for your answers so far.
I downloaded stock rom yesterday and planning to migrate today, due to the fact that a solution for rooting XT1068 comes near.
I just hope i got the right Stock Rom Version for german version and - always a bit worried that someone has put malware in the roms posted on fileshares.
Now I have to find out the right steps with ADB.
Full wipe, wipe cache, wipe dalvik and restore partition required as I am used to do with Samsung crap due to other mounting of sd card? Always did it with CWM the times before and never had to relock bootloader. But I have also read that locking is not required for flashing 5.0.
Okay, lazy saturday, I am going to find it out myself

Nope, no re locking required. Just do the samsung needful. I had one of its ****ty mobile too. So hi5 there.
Anyways, I don't understand why are doing this stuff. Most probably a flashable zip would be uploaded on XDA the same day or max the next day. Just chillax and wait for the good news to arrive, which I hope is any day now
P.S Oh and also make sure that you don't lock your bootloader at all. Because then you wouldn't be able to unlock it, at least not right now, hence you wouldn't be able to root.

[Q] Root and Encryption? (Bootloader locked, Rooted, Firmware 23.0.1.A.5.77)

Hello everyone
I have now finally been able to root my beautiful Sony Xperia Z3 Compact. The bootloader is still locked. I did downgrade the Firmware in order to root the phone. Afterwards I made a backup of the DRM Keys via TA Backup. Additionally I updated the Firmware to 23.0.1.A.5.77. As the bootloader is still locked I did not install any kind of custom ROM and I am yet not planning to do so. The Sony ROM will probably do a good job. (My old phone is a Sony Xperia P which is now running with Root Sony's ROM since 3 years at least)
I am running on KitKat 4.4 and also not planning to change. I have a 64GB SD card in my phone as well.
Now my question:
Can I still use the encryption function or will this interfere or make problems because I have root (Bootloop)?
I am not planning to encrypt the SD card because I do not need encryption on the SD card but encryption for the Android System would be nice.
Thanks for your help guys :good:
Best wishes,
Dicey
No idea guys? Did no one ever try this before?

I'd like to know this as well.
I tried this today. Left it encrypting and when I came back it said encryption had been interrupted and it then did a factory reset, after which I was unable to enter custom recovery.. As I had chosen to encrypt the SD I was left with an empty SD card too.
Somehow I kept root so I was able to install XZDualRecovery again and then restore from nandroid backup.
There's a thread on androidforums where Samsung owners have reported success with temporarily disabling SuperSU while running the encryption.

Anyone tried this method or found another way to achieve root + encryption? It's the only thing keeping me from rooting again.
