CM12 to CM11? - ONE Q&A, Help & Troubleshooting

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.

Htc one s bootloop

Hi iv got a HTC ONE S, it is stuck on boot loop is there any way i can get my pictures and data off my phone? thanks
Can you get into the recovery? And are you running a custom recovery?
If you can get into your recovery(cwm or twrp) you can plug it into usb and mount it as usb storage.
If I helped in any way please hit thanks
Just fix the bootloop. Sounds like you gave up on it. Can you get into the bootloader? Hold volume down and power. Till the device shuts off. Then redo that method and poof. Hboot. If you can. What hboot version are you on?

I have the same problem, phone keep reboot and will not turn on, i can get into recovery, but can not get contact via USB, what am i doing wrong?
Any step by step how to get out pictures before setting it back to factory settings
recovery loop
Just rooted HTC One S TMOUS using Hasoon 2000's tool. tried CWM backup of rooted stock, then followed instructions for PA 2.52 + gapps. Got stuck on PA boot screen. Won't boot all way up.
Phone will only boot into recovery. adb reboot bootloader goes into recovery. can't get into hboot to restore stock using RUU.
Advice?
Thanks kindly.
Same Problem here.
I wanted to join a wifi-network, then the htc freezed and now it's in bootloop.
I still read some oder threads in the internet but not realy good ideas I like.
Does anyone know whats happening in HBoot when I use "Clear Storage"? Does he clear the phone-memory or the SD-Memory? Or anything else?

did anyone solve this? I have an unbranded unrooted HTC One S that is also stuck in a bootloop. I was just scanning the WIFI networks from settings and then the phone started looping by itself and only stopped after the battery was empty.
The phone is not modified in any way. I can get into hboot with power-volume down but then what? I don't really feel like doing a factory reset. Is there any other way out? Does the factory reset help?
Hi
I had the same problem and fixed it.
I made factory reset, then when i configured my Google account i disables the "sync Internet" Option.

Ya seen someone say that not sure if it was you but also some people have found having to many saved hotspots can also send you into a bootloop.
in my case for sure it was the google account cause i did factory reset, and had no saved hotspots and still it happened when i switched the wifi on\off after the factory reset(i mead got into boot-loop and needed a factory reset).
it is a serious bug\problem - i can't believe this can happen because of such a silly configuration.
the OS of HTC is not stabled at all!
If your bootloader is locked, then you dont have too many options re getting information off of your phone. Someone else may be able to post ideas. A factory reset may be your only option..
If you have already unlocked your bootloader, my suggestion would be to flash the latest TWRP Custom Recovery (google it). You can connect to your computer via usb through TWRP and access your sd card to get pictures, videos etc off of it.
Through TWRP you can also have access to adb.exe (ie using adb.exe commands and not just fastboot.exe commands, and thereby access all sorts of adb related commands (backups, linux shell, etc).
In order to actually fix the bootloop, well, usualy I find this is due to issues with the Kernel and custom ROM you are flashing (either one or the other), and so would reflash whatever worked before (ie a previous ROM or previous kernel).
But if this is all happening on a device you have not rooted nor flashed anything custom... Well, then that is a good question!

Ya I'm not saying what you said is wrong or didn't work for you but I do think I could be right about kongo09 and Bond246 issue since it did happen when dealing with wifi and seen a few people say the same thing.
I am in a bootloop. What i did to get the phone start is just press first down volume button then power button (keep holding them until the phone goes oof). Inmediatily when the phone go off, stop pressing anything. ANYTHING, BE FAST, and it will boot normally. I am now tryying to get the stock recovery to avoid this sht.

Did the factory reset make you lose all your data? As in: pictures etc? I have read varying stories regarding this, some say you lose it all, some say you don't.
I have some recordings of interviews on there that I really(!!!) cannot lose. Does anyone know if HTC has the possibility to recover files from a phone in this condition?

If you unlocked the bootloader then you could flash TWRP which will let you mount SD for the PC.

Unfortunately not... Unrooted, stock bootloader and all... I spent all day reading threads on different forums, but so far it seems that there is no other solution to this bootloop problem than just doing a factory reset. But like I said, I have some very important recordings on my phone and before I give up on them I want to make sure I tried everything.
If anyone knows of a way to root and flash a new bootloader without wiping all my data in the process, that would be highly appreciated.
Or if anyone knows whether it is possible to somehow approach the storage (maybe through Linux) while the phone is bootlooping (not normally recognized by computer).
But also: I would very much like to hear from people who have done a factory reset from the stock boot loader: has it wiped just your apps and app data? Or has it wiped your files as well (photos, music, recordings etc)?
Like I said: any info would be much appreciated...

Not much you can do then because even unlocking could wipe SD.
Not sure if its possible with a locked bootloader but you may want to try getting into your bootloader then try typing fastboot boot <working kernel file>
Replace the phrase "<working kernel file>" with a stock boot.img that you know works.
As you can see this command is different from fastboot flash boot <working kernel file>.
This may get you out of the bootloop if you had kernel issues, and may allow you to load a kernel temporarily. Not sure if it works on locked bootloaders but it might.
If all you can access is the bootloader and fastboot, then you really have to play around with fastboot commands. See http://android-dls.com/wiki/index.php?title=Fastboot for the list.
Good luck!

Stock bootloader, same bootloop scenario - factory reset wiped everything including photos, music, other files. Clear storage seems to keep everything except the installed apps and configuration. It's the 4th time I'm doing it unfortunately :

Downgrade from lollipop without losing data

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.

[Q] Dual, Tri, or Quad-Boot?

I'd like to quad-boot my Nexus 5 with Android, Ubuntu Touch, Sailfish, and Firefox OS. Can this be done? I would also happily settle for tri-boot or dual-boot. What is the best way to go about this? My phone is not rooted (yet).
Multirom, probably
Thanks, I've been researching this all morning and I've come up with a couple problems.
There doesn't seem to be a way to do a full backup of the stock phone. A Nandroid backup would be perfect but in order to do that, custom recovery must be installed which requires unlocking the bootloader which wipes the phone. One of MultiROM's features is "Boot from USB drive attached via OTG cable". Can I do that and leave the phone's internal memory 100% untouched so I don't have to unlock the bootloader and wipe the phone?
It sounds like MultiROM itself requires custom recovery so I won't be able to receive OTA updates for an Android booted from MultiROM. Does that mean I will have to wipe Android each time I want to update it?
I don't think there would be any need to root the phone in order to set up and use MultiROM, correct?
You do have to unlock bootloader.
Think you are trying to run before you can walk. With 4 roms where would you store apps as well for them all. Most of those have little support anyway
SENT BY ENTANGLEMENT
Aren't apps written to the ROM are you're using the OS like the rest of the user data?
Lack of support is OK.
Can I leave the phone's memory untouched and install MultiROM on a USB stick? I would think custom recovery would be required in order to boot from USB which would require unlocking the bootloader which wipes the phone.
You do have to unlock your boot loader and root your device for multirom to work,
Just back up your data and restore it after you finish the process.
I currently have an N5 with multirom installed and can boot
4.4.4
Dirty Unicorns 5.1.1
Pure White 5.1.1
Ubuntu Touch
FirefoxOS
The storage space is shared on android roms so you can view your file downloads, music and videos. You can view on Ubuntu Touch
The apps are separated by the Roms, so you can install the same app on each rom with different settings.
I have a 32 GB N5 with 580 songs, Copilot GPS app + data on the 4.4.4 rom, and a 2 TWRP backups (one for original 4.4.4 and one for the multirom) I still have 7.96 GB left of storage
qnc, the problem is there is no way to do a full backup without first unlocking the bootloader which wipes the phone. There are various backup techniques available but none of them restore your phone exactly as it was like a NANdroid backup/restore does.
Android shouldn't need to be rooted in order to install MultiROM. That can be done from the command line with the phone connected to a computer via USB.
Have you tried Sailfish OS? That's the one I'm most excited about due to their Android app compatibility layer.

Ahh understood. I missed the full backup.
I only worry about SMS/MMS backups and pictures. I don't worry about app data.
Question what data would be lost if a full backup is not done?
I have not tried Sailfish OS, I will look into it to see what it is.

Google Authenticator stuff for one thing. But in general the point of a full backup for me is I don't have to think about it and I won't be surprised after the restore.

It's created by the former Nokia OS team in Finland. You can actually run Android apps inside the OS.

I see, I don't use Authenticator much, if at all.
I'm guessing that I probably don't since I don't worry about it. I change ROMs on my phone so much it would probably be a hassle for me.
Sailfish OS sounds very cool I will look at it and flash later today.

So when you want to update a stock Android install, you have to backup/restore since you're using third-party recovery/bootloader?
Please let me know how you like Sailfish if you get a chance.
no i dont have to back up and restore for upgrade
since i upgrade manually i just flash everything except userdata image. i get the upgrade without deleting data.
also i flashed sailfish OS. it is really smoorh.
gestures are killing ubuntu.
im posting in sailfish right now.
Nice, my Nexus 5 shows up today (right after the 5 o'clock free crack giveaway) so I'll be dialing in MultiROM over the weekend.
So you keep your userdata on a separate image? How do you do that?

It is just a matter of flashing each image individually.
I'm on my phone so I can't find the link, but there are directions on how to update while saving user data.
You just flash bootloader, recovery, system, boot, radio images and do not flash userdata image.
You systems is upgraded and you keep you user data and apps.
You then must root and ad back custom recovery, but thstcis pretty simple.
There are directions on XDA I just can't find link on my phone right now.

Android 5.0.1/5.0.2 - Encrypted and Rooted - Bootloop/bricked: Can I recover?

Hi guys, here's my dilemma:
Samsung Galaxy S6 with Android 5.0.1 or 5.0.2 (I forget which)
Rooted & Full device encryption
Want to recover my information if possible; no factory reset
My questions:
Is there a way to fix a system to recover my data on a rooted & fully encrypted device?
Would flashing work, and how would I go about the recovery process?
Do I need to know the exact OS (cant remember if 5.0.1 or 5.0.2)
Is there a way to get the encrypted data copied and decrypted so I can read it again? (I heard something called adb can be used?)
Things I have tried: Powering down for a while, clearing cache partition, etc. This is the 4th time it has happened in 1.5 years, and I'm tired of it. Warranty/insurance affected by root status so would have to pay for $150 trade-in. Just want my data and ideally move to a new phone.
Do you not have a recovery backup you can restore ? What exactly are you concerned about loosing in terms of data.. are you worried about loosing pictures saved on your phone or say.. text messages ?
@fOmey - I'm not sure if I had a recovery backup. I did have TWRP(?) installed, though. I am worried about losing many pictures and also app data (to do lists, etc.) that aren't synced with a cloud service.

Boot into TWRP and check if you have a backup, if you don't have a backup you can dirty flash your rom and with a bit of luck you'll boot into your OS.

TWRP Question - so confused

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.
