SM-A300FU - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

So look,
I rooted my phone succesfully.
Now I want to encrypt my device using the device encryption feature. Ok.
I enter a password and it shows me an Android guy doing his job. Then I dont see anything anymore on my screen... I press volume down plus home plus power and I see this famous error: Encryption failed blabla, I need to reset my phone in order using it.
So, I dont want use the originally firmware, I need a rooted phone... I also need an encrypted phone, so my question is how can I solve it? I downloaded a legal root file and no corrupted.
Please help me, everytime I try to encrypt it I need reset it again.

Help
Bump, I need the help, this is a real issue for me, thanks.

Help
Dont want to spam but someone must have a solution for this issue...

Help
Again asking for help its a serious issue

your failure could be due to root, which causes a permissive kernel. I may be wrong with the terminology as i dont encrypt at all, nevertheless, this question is not really specific to the device, hence why nobody can actually add anything.
Try a more general forum.

Factory reset your device then encrypt. It should work then.
Once encryption is confirmed then you can root.

Unable to decrypt samsung galaxy s4

Hi, I have an i9505 which I have rooted with the help of some of the guides on here.
Anyway, I encrypted my phone from settings -> security not really knowing what I was doing. I was just thinking that it would make my phone more secure or whatever.
Anyway, following this I now have to enter a password every time I lock my phone screen which I find very inconvenient and I understand that I can't install any custom roms in the future.
I have tried to decrypt the phone from settings -> security but the process doesn't seem to complete.
It says that the decrypting process is irreversible ect ect.. it will take one hour ect... ect.. then when I click to confirm it and begin the decryption process the phone just seems to switch off then it turns back on by itself within 30-60 seconds and that is it. The phone is still encrypted?
Can anyone help me please?
I am really gutted!!!
Thanks
I am experiencing the same problem right now, did you ever find a solution?

Encryption is irreversible without a factory restore.

I was keeping my hopes going because there is a "decrypt device" option in the security settings, but that wouldn't work and I was hoping I was ****ing it up somehow. Guess device cleansing is my only option.

Decrypting a Samsung Galaxy S4
Had the same problem several times. Make sure "USB Debugging" is off in the "Developer Options" section of the Settings screen.
Dont fret....go to settings<lock screen and then change it to swipe....Hope this works!

Last night i had the same problem but i managed to fix
If you press decode it says password and then enter a password of at least 6 digits AND AT LEAST 1 NUMBER to activate the decoding part i tottaly missed that but i realized it a few hours after.
And then it started decoding for about half an hour and it was fixed.
Hope this was usefull so you wont need a system reset.
Given that the original post was in 2013, the OP likely had to reset, if none of the other posts from 2013 in the thread helped.
4.1/2 years on - there must be someone out there that knows how to decrypt the GT-I9195 ??
I spent yesterday researching pro's & con's of encrypting my phone. Couldn't find anyone saying password had to be entered EVERY TIME I USE the phone, just people wrongly advising that I would have to enter password every time I switch the phone on. I could live with that, I thought, so I encrypted it. Big mistake. Why anyone wants a phone that needs a password on every use, I do not know.
Please help me decrypt my phone. Thanks

[Q] Nexus 4 security

Hello,
I didn´t find anything about my issue so i´m posting, i have a nexus 4 rooted with PA rom.
Now any rooted phone can be powered down and if stolen that person can try the keys combination to enter into recovery mode, from there its easy to have a brand new phone.
So my question is how to prevent this?
Regards
Rui
There really is no way, at least to my knowledge, to keep people from factory resetting your phone after stealing it. Even if you managed to find a way to get a custom recovery to have a password, which currently doesn't exist, people can still boot your phone into the bootloader and factory reset your phone, even when the phone is encrypted.
Basically, if you choose to root your device, there is no way to secure it so people can't factory reset it to get a "brand new phone".

Help needed, bootloop. spyware?

Hi guys I have a problem, I am using miui7 developer ROM and my phone has been compromised twice, I have had my bank account hacked(long story but calls where diverted and bank log in details changed) and 4 days ago someone tried to log on to my banking app remotely 5 times and so it was locked down, bank has confirmed it was my phone and my WiFi provider that was used and I know it wasn't me, so I have tried to flash 2 ROMs using all the correct methods and it always results in the same, a boot loop, I am wondering if partitions have been messed with, or if there is something hidden on the file system causing this, what I would like to do is wipe everything, I don't mean just system data cache etc I have tried all that unsuccessfully, I mean fully wipe and reset all the partitions memory emc chip and totally start fresh, can anyone help please, I really need to sort it out I know my phone is compromised because of things that have happened. Any solutions please. Anyone experienced malware in miui7 ROMs? Your help is really appreciated.

Redmi note 4g single sim doir, bootloader not sure never unlocked so presume locked, rooted and unrooted tried both methods, flashed plenty of ROMs in the past without trouble.
Sorry but i cant really help since i do not own the device. It would probably be best to try to find a solution on miui forum, directly ask a member of a Dior device team. And don't know if you flashed through recovery or fastboot mode - try both mehtods, also developer/stable rom. I think flashing through fastboot also acts as a full factory reset. There must be a tutorial for unbricking or resolving bootloops. Also try some custom cm/aosp based roms to see if the phone will boot. And since miui is chinese, you can presume that there is some data leaking, but i don't think that it contains malware - it would be too much even for xiaomi (unless you "picked up" some shady script/trojan/whatever along the way).

[SOLVED] - Moto G4 Plus - Encrpytion PIN/PATTERN/PASSWORD Problem

Hi all,
I have encrypted my device and using PATTERN as the security. I do restart device once in a week and it asks encryption pattern to start Android. Today when i restarted, it asked me PASSWORD instead of PATTERN. I tried Google password here but it does not work. I dont understand y its asking for PASSWORD when i have selected PATTERN.
I cannot start my device now. I cannot afford to factory reset as the data is imp to me
Please help/advice/guide.
SOLUTION - http://forum.xda-developers.com/moto-g4-plus/help/phone-password-instead-pattern-solution-t3424457
Guys, Do not encrypt your phone. Motorola dont have any resolution for this problem.
Infact their Engineer told there is no such option which enables pattern/password at the boot up (Can u believe it?). They have such ppl on their support.
My only options are:
1. Delete all data
2. Install custom recovery to access encrypted data. But i believe that will void my warranty.
If anybody has any other solution, please advise.
Solved it
Guys i have solved the issue
Saved my data too. no need for custom recovery.

Need help unlocking my phone, it's really urgent for me

Hello.
I have a serious problem.
tl;dr:
I forgot my pattern lock combination and I need my messages so I don't want to factory reset. Is there any other way?
Long story:
So I've forgotten my pattern lock combination and I have a job interview tomorrow at the address I received in a message.
I can't unlock my phone. I didn't write down the address anywhere else. And if I try to factory reset my phone it will get rid of all my messages.
So far I've tried:
dr.phonw - but for some reason it doesn't work on p9 lite
I've read online you can delete the password file for the pattern lock and it will unlock, I've tried using usb cable to access my files but I can't access the phone while it's locked.
I've tried installing a file manager from a sd card in recovery mode, but p9 lite doesn't have that function.
Do you have any other ideas I could try.
It might seem like a strange question, but I'm really panicking right now, the job interview is tomorrow and it's really important to me.
Any help is greatly appreciated.
