Looks promising thanks for putting this up! I look forward to seeing if this successfully works on the various types of bricks.
Edit: Not sure what's up with your links or hosting, but yeah...doesn't work, just ads, then redirect to ....another ad. No download.
Edit2: Ok I've tried 6 times, no download, and I should mention links like this are frowned upon by XDA Mods, so you may want to switch to a host that doesn't require going through steps to get to the download, like dev-host. Looks like now I can't go past unless I sign up for something, which I may or may not agree with, which is kind of forcing users. Or I'm blind and not seeing it, always an option too lol

yes you can do this

In my case it does not serve for anything. Because as it does not recognize me the tablet by any means. The usb does not even sound when I connect it .... it is a pity, tomorrow a messenger comes to take her to him to the SAT. but thanks for the work
I have a photo of the current condition of the tablet, but they do not stop me to place external links...

I made a little video maybe this helps

This won't get any farther then any other current method on a locked boot loader. This is for those having issues with recovery not responding so a rom install isn't possible.
What kind of brick do you have? There's a few kinds now.
Tapatalked from my Galaxy S II.

I don't know what type it is if I had to guess I would call it a complete brick but fastboot works (locked mode) and it sometimes will work with adb (also in locked mode)

The last step...

E:failed to mount /data (No such file or directory)

That md5 error is normal, and isn't causing the install to fail, its the pretty much brick status your device is in that's causing that. Basically all those errors are saying you have no partitions on your device, so it can't do anything until that's corrected.

any idea where to start or how to get it back so i can return under waranty

Get it back how? Acer knows of the problem so just use the warranty.
Edit: sorry just realized what you meant. Sorry but no in its bricked state you can't restore it back to normal. You could try to fast boot the stock recovery and adb the stock boot loader, but it may or may not work. Doing any if the Modding voids the warranty anyways.

M8 not able to Decrypt

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.
You can find it here: http://forum.xda-developers.com/showthread.php?t=2701376

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!

[NEED HELP] TWRP wiping + flashing ERROR, Bootloop

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.

Infinix Hot 8 lite X650 MT6580 Authentication file

Please Help !!!
While trying to flash stock rom on my Infinix Hot 8 lite X650 (chipset MT6580) using SP flash tool v15.19, i am getting following error.
"ERROR: S_AUTH_HANDLE_IS_NOT_READY (5000)
[User] This is a secure Base-band Chip! Please select the authentication file first.
[Hint]: "
I have selected "MTK_AllInOne_DA.bin" which was already there in the folder of SP Flash Tool, and Scatter Loading File from the ROM folder.
Have been searching for auth file of Infinix X650 on google for the last 4 days but no luck.
Have tried almost every solution available on internet.
Please Help, my phone is soft bricked!
PS. I rooted my phone using TWRP and Magisk after which the Wifi and Bluetooth stopped working. Then I attempted a Factory Reset and now my phone is not booting, it just directly goes into TWRP when I power it on.
And while trying to install the ROM using zip file from twrp, or while trying to wipe it, or repairing the partition, it gives following errors:
"Failed to mount '/system' (Invalid argument)
Failed to mount '/vendor' (Invalid argument)
Failed to mount '/data' (Invalid argument)
