Hi all,
This question must have been asked a thousand times but not precisely as follows.
I have TWRP installed with Cyanogenmod 12.1 Nightly on my HTC One M8 (International)
If I were to encrypt my phone, through settings --> security --> Encrypt storage/Phone that is,
What effect would that have on recovery backups?
Lets say I encrypt it,
Go to recovery and make a full nandroid backup. would that be possible in the first place, And if so what would be the result of restoring this backup? would I have my encrypted /data partition again that I can acces with my pattern unlock screen which is also still the same.
Would I end up with a bunch of unreadable files?
Or would TWRP not allow me to backup my data in the first place?
edit: the reason I'd like to encrypt it is because I have an unlocked bootloader with TWRP and cyanogenmod and therefore anyone could simple hop into my recovery from boot and extract all my data to an otg-usb or something along those lines.(BTW, is the performance hit in real life significant?)
Thanks
Hi, thank you for using XDA Assist. You know, the best place to ask is in your device's specific forum here,http://forum.xda-developers.com/htc-one-m8/general. But if you back up an encrypted device with twrp it'll restore it to just like it was when you backed it up, encrypted.

Thank you, that answers my question
cheers,
Great! Don't forget to use your device's forum in the future. I'll close this thread.

This is probably a silly question, but I hope some more experienced Android experimenters can help ease my mind. I'm an Android noob, but I do know enough to follow instructions and I've successfully installed aorth's CWM Recovery and made a backup. (If I understand correctly, this is called a Nandroid backup and represents a complete backup of the system. Please correct me if I'm wrong.)
Now my Tab boots into CWM Recovery when I hold the volume-up key. It sees my backup when I select the "restore" option. All that looks as I would expect it to.
My question is: How safe is it to play around with flashing other firmwares, for example CyanogenMod 10? Will I always be able to get back to where I am now simply by booting into recovery and restoring? Or is it still possible for something to go so horribly wrong that that won't work? On a scale of 1 - 100, how high are the chances of being able to recover no matter what?
(BTW, I do have a copy of the backup on my PC, so if it got wiped from the Tab I would still be able to get it onto the external sd card.)
I am not a developer by any means. But I love to tinker. My rules are. Read everything. I have never been unable to restore a backup if somthing seems to have gone wrong. These guys are not out to mess up your device. Once you understand the terminology and flash a few it will bring new enjoyment to device. Go for it.

Hi guys,
I've got 60 phones to setup, and that's just the biginning. I looked for some solutions to mass deploy them, the fastest way possible. I of course already know titanium backup and applications like that, but i would prefer not to root phone...
I was pretty confident about a nandroid backup : flashing the recovery of the phone is really quick, and i would just have to backup on card or on usb on the go on the master phone, and to restore the backup on all the phone remaining. But it didn't worked as expected, it happens that on each phone, twrp is generating backup in a folder named something like "420khg66g6cca200" and which is different on each phone, and when you put the card in another phone, this one doesn't see the main backup.
I of course tried to sneak arround and generate a backup on the second phone, which i replaced with the content of the first one, but the phone doesn't even boot anymore.
I used twrp because i dind't find another recovery avaiable for the phone, which is by the way a samsung Xcover 3 also known as SM-G388F.
I tried to backup only system, system image, and data and to restore it and the phones is stuck on boot screens.
I tried to backup again with boot partition, same thing happen'd. There's something i don't understand tho, there's some warning about /system partition which can't be mounted when i look around on the recovery of the slave phone.
I'm on stock rom, no root. I looked for similar post (really), but there's mostly guys which make backup / restore on the same phone, and i didn't find my answer.
My questions are : is there someone's who did this before ? Why the phone doesn't boot anymore ? Is there something that's making the backup unrecoverable on another phone ?
In this case, is there anyway to bypass that ?
Thank you by advance.

ok, sorry for the wrong category.
Alright, i messed up real good.
I bricked my note 4, i did root it no problems there
then i installed TWRP, and it all works just fine
but then i did the mistake (such a rookie mistake iknow) i haven't been flashing for a while and i forgot
i wiped the whole thing instead of just the cashe, with that being said i can still boot into the stock recovery and the TWRP recorvery but no system nor the backup i made because im a dummy
i cant really figure out what to do next, hope someone can provide a solution
Hello, and thanks for using XDA Assist.
What you should do in this situation (since you didn't make a backup first ~ always make a backup) is download a ROM onto your PC, transfer that ROM to your extSD card, then boot to TWRP and flash the ROM. That'll install an OS back to your device.
For future reference, there is a dedicated Note 4 help forum that you can post to, where members who own the Note 4 can give you expert advice with any other issues that may come up later in time.
Good luck!

Thank you! ll post there, i haven't been on XDA for a while, and the frustation was killing me
i did make a backup but it's gone gone gone :!
I'm some kind of experienced with ODIN, but I'm not sure with some things, I'll be very grateful if you can answer my questions.
Will flashing a stock ROM *touch* the /data partition ? There is nothing related with data in my Rom package, and NAND Erase All is not enabled. I have some important data to be recovered so I can't let it be touched.
Also, what software do you recommend when I am trying to recover deleted data on a Android device? Either an Android app or a PC app is okay.
Thanks a lot.

Could someone please send me a twrp backup of the Alcatel pop 4 ( 5051x ) or the stock rom to fix the bootloop im stuck in.
I tried the mobile upgrade tool but it, just says device is on latest version available, so im unable to reset it back to factory without a backup of the device or the original rom to flash.
Any help would be great.
Thanks

This EXACTLY why we make such a big deal out of MAKING A BACKUP BEFORE MODIFYING A DEVICE. It is the very FIRST thing you should do just as soon as you get a custom recovery installed, you should make a backup BEFORE doing ANYTHING else. Some people never learn.

I did make a backup but I can't seem to find it on my hard drive anywhere :/
I usually make more than 1 backup but didn't this time.

It is wiser to store backups on an extsdcard inserted in the device.
Keeping TWRP backups on PC instead of the device can lead to not being able to use that backup if the device can't connect to PC. If your device will only boot to recovery but won't connect to PC to transfer your backup then it leaves you unable to restore the device.
Keep backups on PC for alternative safe keeping but it shouldn't be the main or only place where you keep backups.

I have now fixed my device, and I have made a github page on how to restore/un-brick the Alcatel pop 4 (5051x), back to factory rom.
If need link to my github. Please private message me.
Thank you
