Hi everyone
I received an update notification a couple of days ago and updated my oneplus one to lollipop. however I really don't like it, it messed up with many of of settings(taskers,profiles settings etc) and I want to downgrade now back to how it was before.
I didn't backup before updating, is it possible to downgrade without losing data?
thank you

Yes you can downgrade without losing internal storage data only!
All apps with it's data will be lost
I followed this guide for that :: https://forums.oneplus.net/threads/guide-how-to-revert-back-to-cm11s-from-oxygen-guide.290605/
This will work only if you have unlocked bootloader and you are on TWRP recovery(As I tested on it and this works for CMOS12 or any other lollipop based ROM too)
thank you for the reply. Losing apps data it's a problem then, I have apps with data,configurations,settings etc and if downgrading ends up resetting them then it's a problem.

Do you have root? If not, root the device and then you can use Titanium Backup to backup all of your user apps (along with their data), then once you've reverted to KitKat you can root again and use Titanium to restore your apps.

Nexus 5 stock 4.4.2 ROM.
What would cause this on rebooting? After the popup error booting continues and the phone seems to work correctly.
I deleted both cache and dalvik cache but that didn't help.
What is Process system?
Thanks.
Maybe you need to factory reset your device. Or if you rooted clean flash your rom.
Probably some of the system files got messed up? If it's bugging you, Flash the stock system, boot images and re-root.. Apps and it's settings can be backed up and restored via Titanium Backup.
Seems pretty radical. I was hoping for something less radical.
If I reset won't I lose all my system settings, accounts, and who knows what? I don't think tibu can restore those, can it?
If I accept the ota update to 4.4.3 (despite the problems about the radio, etc) would that overwrite all the system files?
I have nandroid back-ups and TWRP if that is helpful.
I am now having problems with widgets not working, Tapatalk not refreshing, etc.

It takes about 10-15 mins to setup your google, other accounts and system settings.
No, OTA update won't delete anything. But if you have changed any 4.4.2 system files you shouldn't install the OTA as it would break and abort installation.
If you have the nandroid backup of your complete stock rom, you could restore it and then proceed with the OTA. Kindly refer to the OTA helpdesk in the General forum which will clear all your doubts.
Thank you again.
I took the plunge, uninstalled xposed, and accepted the ota. It updated with no problems - but I lost root. So I will spend the 10 minutes rerooting instead.
On the good side, after the update, the error no longer appears and the widgets work again.

That's great! Good to hear.
Thanks. I wanted to post my solution so others might benefit.
While searching for a solution I discovered that several others have faced this problem. So it is not that rare.
First, I apologize if this has been answered already.
I'm currently running DH GPE Lollipop 3/6/15 due to an update issue that forced me to downgrade.
Last week I updated TWRP to the latest version, then tried flashing the most current DH GPE Rom and ran into a boot loop. 20mins with nothing happening. Restarted and reflashed, still nothing. Flashed the version I had running before and same thing. I ran a TWRP backup month ago, so I just flashed that but lost all my SMS/MMS and current apps.
My question is, what is in your opinion the best way to backup SMS/MMS and Apps?
I hear a lot of things about Titanium, but I don't find it very easy to use and complicated. Would I be able to backup Apps and my text messages with TWRP and reflash them after I install a new update?
Thanks

my best option is my backup pro.It is best for SMS/MMS/Apps/Contacts/Aps..
SMS/MMS I use this always.

They also have call log backup too if need. Works flawless like 3 clicks

why do you say titanium is complicated?? Its quite easy. I've been using it since my Galaxy S days. Once you make your backup just move it your external sd card. I also never restore data, just user apps.
+1 om SMS Bacup and restore. I always back up to my google drive.
When I wipe my phone first app I download is Titanium, then I restore my apps, the restore my sms/mms with SMS back up and restore, takes about 20 minutes, maybe.
Hello folks,
I dont really like the CM12 update.
I have some weird battery drains..
Is there any way I can downgrade to CM11 WITHOUT earing my user data (photos & whatsapp backups for example)
If so how?
If not, how then?
Thanks for helping!

You can easily go back to KitKat without erasing your personal data (images, etc). Backing up your apps requires root though, which requires a custom recovery, which in turn requires an unlocked bootloader. Herein lies the problem, unlocking the bootloader will erase your personal data, so unless you did this when you first got the phone you're kinda stuck.
I've grown tired of bugs in Marshmallow (clock/time issue and notifications rarely working to be specific). I'm planning on downgrading to Lollipop. My question is... is it safe to restore apps and settings with Titanium Backup after doing so?
I was worried the settings for some apps might be saved based on a Marshmallow configuration, so if they were restored on an actual Lollipop configuration, it could cause problems.

It should work fine as long as you don't restore system data.
If you downgrade and the phone is stuck at the boot animation, you may have to perform a factory reset.
Hi all.
Hope someone can help me. When I got my Samsung S8+, I quickly installed TWRP and then rooted it with magisk the same day I received it.
After that I removed a LOT of bloatware and installed hundreds of apps and everything was fine for 6 months.
One day it gave me a weird lock error, because I think I accidentally removed the OEM Unlock and the phone went crazy.
I had no phone for a few days but eventually I managed to flash stock rom and phone went back to normal.
I lost root, but I managed to keep all my data.
Now I want to see if I can get root again. However, all the tutorials to get TWRP require that I wipe my phone.
My questions are:
Can I root my phone without wiping all my data? Is there a chance that my bootloader is unlocked already or did flashing stock rom remove that?
If I have to wipe my data, how can I keep all my apps (and the app data). I have Titan Backup but that needs root to work so I don't see how to save the app data?
Thanks

Inorder to root, you need twrp and in order to get twrp working you need to wipe everything first.
I don't know if there is the possibility to backup app data without root, however i found this articel.
Just because I'm curious, which apps are important for you to have a local backup? I went through all my apps and didn't found a single app which isn't either naturally stored in the cloud (like whatsapp, FB, Snapchat,..) or has the function to export/backup things like tasker. :fingers-crossed:
Hi Jaannis.
I have a lot of apps that do not store their data in the cloud but locally in the phone. Without being too specific, some of these are notes, some are social apps (connections with hundreds of different people around the world with conversations, pictures and videos) and some are personal collected data.
I managed to migrate all the data the last 5 years using Titan and I think it's silly after managing to save them suddenly to lose them. On the other hand it kind of looks like there is no other way. Without Titan backup working, I will need to lose everything.
