Hi, I've recently encrypted my M8. After using it almost a Month I've to say that performance has decreased a lot.
I don't want the Encyption any more, but when I try to decrypt the phone going to "Settings/Storage/Phone Storage" Encyption option is grayed out.
Ok, so I tried getting wrong 30 times the password when it boots, but when it says that is going to perform the Factory Reset, suddenly stops and restarts whitout wiping the phone.
As well when I get into Hboot and select Factory Reset, and also using TWRP option to Factory reset the phone the next text appears on the log:
===================================================

Hello,
You have to have stock recovery before you are able to do a factory restore. If you know your CID you can download the correct recovery for your device and flash it.

He's not trying to do a restore, he's trying to do a reset, which you can most certainly do without a stock recovery.
He can also do a "factory restore" without a stock recovery by flashing a stock backup, which he can get from many threads here.

Do you have a nandroid from before you encrypted? Flashing that should solve the problem. You could also try flashing a new ROM with a full wipe.

I had latest TWRP and came across that same error and it's mentioned in other threads about that same version TWRP giving mentioned error.
Flashed 2.8.0.3 and never receive any errors
Its a known bug in twrp altogether....not just one build or another....

Ok, I have given a try twice.
I flashed "openrecovery-twrp-2.8.0.3-m8.img", first try was doing a Factory Reset from recovery and the second using my 30 password attempts wrong on the encryption screen and nothing different happened, same error.
I used this options as it was the easy way, but since it didn't work for me, I'll flash a Nandroid backup or StockRom.
I apologize I didn't reply before, I'll report any issue just in case someone goes through the same problem.
Thank you all.
Been developing a long time...not a debate..lol...and your right you wouldnt have that issue with "philz" as its cwm and not twrp....

You won't believe what the solution was...
1.- Download the latest TWRP available (openrecovery-twrp-2.8.1.0-m8.img).
2.-Enter to Recovery.
3.-Go to "Wipe->Format Data" and type "Yes"
4.-All Wiped! (Internal Storage)
This option was developed to remove encryption, I didn't know about that before.
But now you know as well.
Thank you again for your help!
hello,
does someone know what problem i have and how i should fix this?
first of all, when i was wiping my phone it all went fine but it took to long so i turned off my phone and turned it back on, i got in an boot loop and couldnt even get into recovery mode because that would also led me into a ''teamwin'' bootloop, anyway i reflashed my recovery so luckily i can get back into recovery, but i still have bootloop for the system so i cant start up, but now i also face this problem.
i wanted to flash stock rom and this is the full error log i get ( i also tryed with custom rom but same problem)

I also tryed wiping my phone, i tryed advanced wipe and full wipe and also factory reset, but i always get this same kinda error.
anyone know a fix for this?
Which version of twrp do you use?
i use Twrp 2.8.7.3
Try the last one : https://dl.twrp.me/Z00A/twrp-3.0.0-0-Z00A.img.html
Your zenfone 2 is WW or CN?
its CN
sorry for the kinda late answer tho,
well i wanted to flash the 3.0 twrp version, but it gives me an weird kind of bootloop, so thats why i downgraded to 2.8.7 :/
that's strange, are you sure it was for Z00A?
Look at this : http://forum.xda-developers.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596 to change to WW version.
Can't install iron rom 3.1 because of
"Failed mount /system(invalid argument)". After clicking install in AROMA, there is failed mount /system and formatting system...
After I see formatting system tablet boots only to recovery and dw mode.
Tried to reinstall firmware and TWRP. Nothing
Solved! Just changed to F2FS then to ext4 via twrp
Help! I flashed the Android Oreo Pixel 2 Mod over Android Oreo 8.1.0 with my apps and data on it, and then the phone wouldn’t boot. So I went back into the recovery (TWRP 3.2) and tried to wipe the phone. TWRP wiped everything except for /vendor, returning the error “Failed to mount /vendor (invalid argument),” and "Failed to mount /system (invalid argument)". In TWRP I also tried mounting /system and /vendor, but it wouldn't let me check the box. So tried installing the stock android from the google page, and while sending sparse file ‘system’, It says FAILED (data transfer failure(Unknown Error)). Please Help, I’m a pretty much a noob at this kind of stuff.
EDIT: SOLVED
After browsing online, I wiped the phone one more time, re-flashed TWRP, tried a few commands, I tried repairing the file system of /system, re-installed the vendor.img(probably this), then It worked!
I'm just thankful it works now.
TWRP won't start after updating from 3.3.. to 3.4.0-0 using fastboot. Output includes "Failed to mount '/data'" - see following post.
I guess because I accidentally ran fastboot unlock although it was already unlocked. (The TWRP website fastboot update procedure starts right back with installing the tools and I jumped in at the wrong place)
Tried installing previous TWRP version but no dice.
Any ideas?
I did a TWRP backup before all this. Not exactly sure where it's located but would like to recover it if possible. Will a factory reset likely overwrite it?
