I've been trying some various ROMs to figure out what I do and don't like.
Latest one I tried was Hyperdrive 8.1. Downloaded, checked md5, moved to an SD card and flashed just like normal.
When it boots up after installation and selection of features, the phone states that the encryption process failed and I have to reset data etc.
I'm able to restore to a backup of another ROM through TWRP just fine, but I'm still curious as to why this might be happening.
I'm running TWRP 2.6 now, I was running the latest 2.5 build when I first tried this ROM.
I did a factory reset, cleared dalvik, system, data, and cache before every installation attempt as well.
The phone is up and running fine, didn't brick at all, but I really like the features of Hyperdrive and would like to check it out.
Any help would be greatly appreciated!
Thanks in advance.
Hey guys.
So last night I was trying to update the rom on my Nexus 9 from a 5.02 release of AICP to the latest one. I boot into TWRP and it asks me for my pass code, then I take a backup, clear the caches and try to install the rom (from the internal storage). I don't think it gave any error messages, but when I rebooted and it got to the screen where you enter the password (I'm guessing where it decrypts or something), it said something about an internal error and that I should contact the manufacturer - when I tried to put the password in it just says that settings crashed over and over.
I tried to restore the backup; as well as factory reset and install the new rom fresh; I keep getting /vendor mount issues, etc. I even tried deleting the system partition and installing the new one, still no dice.
So I'm basically dead in the water at the moment (with no OS at all haha), does anyone have experience with this or any ideas for what to do? All ideas appreciated and thanks in advance.
There may be other ways, but I would suggest booting into bootloader and fastboot flash the stock 5.1.1, factory image. Tutorial here > http://forum.xda-developers.com/nexus-9/general/guide-how-to-unlock-bootloader-flash-t3035153
I finally managed to find a working fix for this issue after having found this post. The origin of the problem is TWRP:

Formatting /data in TWRP uses up all the blocks, but encryption from Lineage needs 16kb of free space at the end of the partition to store the headers.

You have at least two solutions to fix this issue:
Resize your /data partition to free up the needed space. Here and here are guides how to do it. I haven't give it a try, so I can't confirm it's working, but several other guys reported this fix working.
If you're not comfortable to resize your partition, you can use an old version of TWRP. Beginning with version 3.2.0.0 TWRP seems to use up all blocks for /data. So you need a version prior to this one. I've used TWRP 3.1.0.0, but 3.1.1.0 should also work. Step by step:
Download and flash TWRP 3.1.0.0.
Boot into recovery and do a factory reset: Main menu -> Wipe -> Format Data (confirm with "yes"). I also wiped Cache and System (Main menu -> Wipe -> Advanced Wipe).
If you're going to flash a Nougat based ROM you can stop reading and start flashing and encrypting
If you're going to flash an Oreo based ROM you now need to update your TWRP version as anything prior to 3.2.0.0 doesn't support flashing Android 8.1. The official TWPR version sucks because you won't be able to decrypt your phone when booting in recovery. I've used the TWRP provided in this post.
Install your preferred ROM and encrypt it.
I haven't tested it, but dirty flashing a ROM (without a factory reset) might also work. But this usually leads to some random ****ups.
Also the TWRP alternative "Orange Fox" was mentioned as a solution in this thread. I actually can't remember if I've used Orange Fox to factory reset my phone or if I've flashed it only after having performed a factory reset using TWRP. For me Orange Fox didn't work (= encryption didn't work). But you might give it a try...

Hi guys,
I'm kind of stuck right now because I cannot encrypt my phone anymore and I don't know why. I got my phone last year and installed LOS 14.1 right away. For security reasons I also encrypted it - without any issues whatsoever. When LOS 15.1 came out, I upgraded my phone, with encryption still working. A couple of days back for some reason I decided to do a factory reset. Obviously, the device wasn't encrypted anymore after the reset. I then installed the new nightly of LOS (20180807) and tried to encrypt my phone once again. When I select "Encrypt phone", I need to enter my PIN, the phone restarts and reboots without encryption being started.
What I've done so far:
I've flashed two different TWRP versions: 3.2.3.0 and a customized one (https://forum.xda-developers.com/re...other-development/rom-lineageos-15-0-t3690465).
I've clean installed different LOS versions (unofficial LOS 14.1 and LOS 15.1 starting from the 20180710 release)
I've clean installed Omnirom (current release and a release from 20180107).
I've even flashed MIUI 9 and reinstalled LOS thereafter because some guy in the above mentioned LOS thread wrote, that this did the trick for him.
I've disabled WI-FI and mobile data before trying to encrypt my phone, because I found a blog article stating that this might help.
Nothing helped. The phone just reboots and stays unencrypted.
Do you guys have any additional hints or ideas how I can manage to encrypt my phone once again? Could another TWRP version do the trick? Is TWRP even involved in any kind when it comes to encryption of the OS? Do you think another ROM could be helpful?

Try orangewolf recovery ....

I'm also having trouble with this. Many days ago, someone told they had successfully encrypted their phone. I tried to replicate what he did, got miui.eu and flashed LOS afterwards.
After tons of restarting, reflashing, all kind of stuff, the encryption still doesn't work. Pfff.

Thanks for the advice. But I'm afraid it didn't help

That's the most ****ed up part. For some people it does work, for some not.
There surely must be some ridiculous small detail we're not getting. Like disabling WI-FI while Bluetooth is enabled.
Things I've also tried:
installed a new kernel: ElectraBlue (https://forum.xda-developers.com/re...rnel-electrablue-kernel-redmi-note-4-t3655651)
flashed an old LOS 14.1 with kernel 3.18.31 which I found here
used different screen lock types (PIN, password, pattern, swipe)
charged my battery up to 100%
reformatted my data partition with f2f
Of course, my device is still unencrypted...
Has anyone any idea why encryption might fail? I mean, it did work in the past with LOS 14.1. So why does it even fail with an old release of LOS 14.1? I don't do knowingly anything different to all the times I've successfully encrypted my phone in the past.
Does the factory reset still leave some files untouched?

Mmm, maybe it's about the firmware? I was almost going to try lineageos 14.1...

Huh... I didn't even think about the firmware. That would explain why the one user who flashed MIUI before installing LOS could actually encrypt his phone. I'll definitely give it a try.

I'm looking forward to hear the results. I'm about to become insane because of this encryption issue.
I've flashed both the dev and stable firmware found in this thread. No success
By flashing I mean factory reset, flashing the firmware and then installing LOS. I noticed, that flashing a new firmware while a ROM is still installed leads to some random ****ups.
After a couple of days of flashing, factory resetting, re-flashing, reading and a lot of cursing I finally found a working solution. I've added the fix to my initial post. Hopefully this helps
I was looking for solutions for quite a while and nothing else worked but did this and my device is encrypted again.
Thank you!

You have save my day "my MIDO" hehehehe
After the 1st PIE Rom the encryption was broken.
Your Step by Step save this and now Syberia 9 was able to encrypt with success :good:
Thank you one more time for sharing.
Thx!

Orangefox worked
is there any plan to fix twrp itself?? thx
Thank you. It worked for me to get Havoc OS 9.0 with hardware encryption on my Redmi Note 3 SE.
I bypassed unlocking the bootloader by doing this. Then I installed TWRP 3.1.0.0 from the recovery, did the reset and everything as instructed here, updated it to 3.3.1.0, rebooted, then flashed the Pie ROM and latest gapps without any further wiping.
I use the first link, I've modified the partition size -> did the trick wihtout formating nor loosing datas
Great, thank-You.
Hi, I want to ask, what is this encryption features you been using? can u tell me?
Today i wanted to upgrade from Nitrogen OS android 9 to PixelExperience android 10 and it didn't work at all...
At first i wiped:
Dalivik / ART Cache
cache
system
Data
And now I just don't know what to do, because after flashing PixelExperience, I got the message: "No OS installed! Are you sure you wish to reboot?".
After that I flashed disable force encryption and rebooted anyway just to see the fastboot screen.
Then i wiped everything again and tried flashing my old ROM without any success (error 7) after that message,
I wiped everything once more and flashed vendor-firmware (it was an old version the name of the file is: "fw_beryllium_miui_POCOF1Global_V10.3.7.0.PEJMIX")
and it still didn't work...
Now I searched online for any solutions and just downloaded a new firmware (filename: beryllium-9.4.1-9.0-vendor-firmware.zip) flashed it,
and after trying to install any of the above mentioned ROM's i got the same results.
I'm kind of desperate right now and don't know what to do. I though that i could maybe format my phone,
I saved all my important files on my PC so that isn't really a problem.
Please help me! (Please let me know if you need to know more info, I hope I didn't forget anything)

I found a old backup, that i made in twrp and after loading that, i was able to flash stuff again, sorry if i inconvenienced anyone
Same happened with me when i flashed PE 10 from PE 9 PIE..
So i flashed Letest Miui 11 (pie) via fastboot then
Installed PE 10 via twrp..
so this is the fix.
Hi
A couple of months ago i decided to change my battery because it was draining for nothing, before that i tried to downgrade to miui 9 and 10, and it didn't change anything, so i thought that the battery was the problem.
But even after changing the battery, i still had this drain issue, so i thought " Miui 11 and kernel?" , so i downgraded again, flashed the optimusdrunk kernel and nothing !
So this morning i decided to tried another rom, the pixel experience, i didn't wanted to do that in the first place because i wanted to keep features such as native call recorder or screen recorder. But i've rather loose thoses features if that can help with my battery issues.
I follow the steps of this tutorial : https://forum.xda-developers.com/poco-f1/development/rom-pixel-experience-t3967593
And after i wiped dalvik, cache, system, data in TWRP, flashed the rom then factory reset, the rom was succesfully installed, i booted the phone, google logo appeared quite fast, then gave me this " Enable Encryption, please wait a while blablabla" , so i wait, at least 15min , so i figured something was wrong right?
So i rebooted the phone after flashing the twrp recovery again (it always dissapeared when i flash a rom i don't know why..), boot into TWRP and i wanted to see if i did something wrong, but i realized that my sd card didn't show up, and all of my roms was not there anymore , and TWRP says that there is no space available (0mb) (because of the factory reset), so i plug my phone into my computer, but i can't transfer anything to it!!
Now i'm stuck with a phone with no system, and no ability to transfer a simple zip file to flash another rom/firmware
Is there any other way to transfer files or flash a rom with adb command ?
Does that have to do with the encyption thing ?
Cheers
