Does Honor 7 support full phone encryption?



Hi,

I'm thinking on buying the EU version of the Huawei Honor 7 device (PLK-L01).

The one thing that is still an open question for me is the support for full-phone encryption.

Can anybody please verify if it is possible to fully encrypt the phone?

Thanks in advance for your help.

Regards,
Pawel S.

Boot Sound locked when using Encryption



Hi Guys,

I just want to preface this by saying I cannot root my phone. Not because I am incapable but because this is my corporate phone and I would no longer be able to use it for work related things if I rooted it.

I am using a Bell Canada Samsung Galaxy S6. Every person I've come across that has an S6 or newer samsung phone is able to boot up on silent and not get the samsung noise when the logo comes up. I tried doing a hard reset on my phone just to test to see if my phone would boot silently if I set it on "Mute" mode and it did WITHOUT encryption but I am forced to use encryption by my company's device management policy app or I can't access other things like my e-mail.

Having said all this, does anyone know how to get the device to boot silently without rooting with these factors in mind? I reached out to samsung and they were clueless. As far as the support knows, the phones cannot boot without the noise even on "Mute" mode which is clearly not the case.

I'd really appreciate any help and insight. I've tried the Silent boot app as well with no success. I've noticed this happens only when encrypted and upon checking the volume settings on the screen where you have to put your encryption password after booting up, the volume settings are kicked back to default. This has to be the dumbest and most annoying oversight ever.



"Encryption Failed" - Phone Will Not Factory Reset



After searching through countless threads on this site, I've had no avail in resetting my Rogers Samsung Galaxy S6 running XtreStoLite 2.2.

A little while ago, I thought it would be a good idea to encrypt my phone with a custom ROM installed. I knew I had recovery and download mode, so I thought It'd be no biggie. Left the phone on overnight encrypting, came back 24 hours later and knew that it hung somewhere. Booted it up and this screen came up: Reset it and restored from TWRP backup, the same screen right here came up: http ://i.imgur.com/J37aZaq .png (sorry XDA will not let me post links, remove spaces) after this, I tried pressing the "reset device" button without success. It just rebooted the phone. Tried to restore from a different backup, no avail, then I tried to flash my custom ROM again through TWRP, no avail. I download ODIN and flashed stock Samsung firmware onto it and it still gave me this screen when I was done. Tried going into TWRP and factory resetting (where it wipes all partitions) and nothing happened. Currently, I'm trying to flash my Samsung Galaxy S6 with the stock firmware through ODIN with the "re-parition" box checked.

It seems there's a hardware flag of some sort stopping this from working. I mean, my file system is brand new, reset to factory defaults, I even checked with ADB and everything has been formatted. Checked with TWRP file manager and everything is good. But I can't get past the "Encryption Failed" screen.

Help me! Thanks.

Encryption fails??



Hi
Anyone have an idea, why after installing a custom rom eg. blispop/excodus or whatever, after flasjing and booting the first time (whit or whitout gapps) i get a encryption fail . saying this was interrupted and not done....try factory resetting (button at middle off screen, says reset) and doing so don´t change anything, manual wiping also changes nothing...??

I´ve never seen this prompt before and not sure what it exactly means?
It happens after flashing cos official 2.14, with twrp 2.8.7.2 , all flashed just fine and working...in cos.
Flashing custom roms gives no errors and seems fine, it boots to the point where this encryption thing shows up?

Tried fastboot oem unlock, which adb says went ok, but no changes whit this error!

Oh and i merged internal sd when i was in cos 2.14 recovery and it works just fine

thx in advance guy´s :D

Device Encryption vs unencrypted Device



Hello there. I have some questions regarding device encryption. If I have a unencrypted device and I secure it via password (no PIN), I can't get access to the device and its data, without entering the password.

What's now the benefits of encryption?

BTW: if I understand correctly, I can access a smartphones data also via some special Bootloader (UFED Cellebrite). This seems to be also the case, if the device is encrypted. Is this correct?

seeking ROM with specific reqs: no encryption and 'native' true silent mode



Hoping to pick the collective brains of XDA forum members:

Do you know of a stable, customizable, frequently updated ROM with good battery life which doesn't force encryption (although I found this in case I have to work around my encryption requirement) and has built in true silent mode? If such a thing exists, I'm all ears.

tl;dr special snowflake details:
I can't work out what benefit encryption brings me other than a performance hit, so I want to ditch it. The NSA is welcome to look through my somewhat mundane photos and documents if that is how they get their jollies.
The xposed implementation of true silent mode seems buggy when I ran it on 5.1.1 stock (sometimes volume down would make it go up, then down after a few more presses).
Having my battery last all day is pretty much my number one concern, followed by lashings of customizability.
Bonus points would be some way for me to override forced screenlock on corporate policy--as long as I can still remote wipe.

If it does all these things, has a good sense of humor and likes to take long walks on the beach, then you've found me my daily driver.

How does the WhatsApp's messages storing encryption work?



Hello everybody,

This is my first message.

What I would like to know is how WhatsApp encrypts the databases. I mean, does it use simple encryption or asymmetric (public-key) encryption? In case it uses simple cyphering, it would be possible to create a cyphered database from a SQLite file by using the key file located in the "hidden" WhatsApp directory but, in case it uses public-key cyphering, I don't know where the public key is located nor how both keys are generated.

If you root the device and the encryption is simple or symmetric, it would be easy to generate a "false" database but, in case the encryption is asymmetric, it wouldn't be so easier and it would be necessary to generate a public-private key pair.

Does anybody know how does it work?

Thank you very much!!!
