I get that too. I have no trackpad at all so I use Rom manager and get that error. Also I've emailed you koush just wondering if its possible to add alternate confirm button for recovery. Power or many or something. I need to buy replacement trackpad otherwise lol.
I get the same issue. I tried ext2 3 and 4.
Can't wipe ext so it makes the recovery not very useful as I use a2sd.

I had this problem when using an EXT4 partition, fine with EXT3. I would try formatting your EXT to 3 and try again.

I am using the latest and no previous desire compatible recovery has worked for me. I will try formatting via Linux and try again
Currently got ext4 but had ext3 previously to no avail either

Seems like you got the partition tables messed up.
I'm no pro so I don't know what could be done.
Hey All, Thanks.
Fixed it some how.
First downloaded FOTA bricked. followed the steps.
Then tried to flash latest GB with his latest/old flash tool (linux). but that didn't work
tried older Flashtool windows Version 0.2.9.1 with firmware 4.0.A.2.368 (This was my rescue)
Finally phone booted

What? You flash tar files with Odin not zips, and are you using the PC version?

Did anyone ever find a solution to this problem. I'm having the same issue after doing a soft reset through the settings menu. Through Philz touch recovery wiping dalvik cache does not work and same error messages you receive come up when trying to wipe user data/factory reset through recovery. This is becoming really frustrating because I know there is a fix I just can't find it anywhere. Please help!!!!!!!
You need to debrick image and reflash/fix the corrupt partition on your phone. Go to the following thread. .http://forum.xda-developers.com/gal...a-unbrick-t-mobile-s-iii-qhsusbdload-t2904318 and if you follow exactly, down to the millisecond, as instructed, you will succeed, that is assuming your device is still able initiate into "download." mode and MOST IMPORTANTLY, you have your device specific debrick image. . If and when your device does succumb and is back online, give your utmost thanks to docholiday77.

Problems with data partition

Hi,
I tried to flash viperOS using squid twrp for moto G5S, but something in the process i think i did wrong.
My phone model is montana xt1790.
I unlocked the bootloader.
I tried to install the recovery, but had same problem than @dau999

Bootloader gives me a notification that the img is not signed or corrupt (squids one)

I tried to flash "no-verity-opt-encrypt-5.1.zip" file posted as solution here https://forum.xda-developers.com/showpost.php?p=74813124&postcount=23.
After this i have working the recovery, but i believe this is what did wrong:
With debug mode enabled, after a wipe clean (Cache, Data, Dalvik/ART and system) and format data (wipe all your apps, backups, pictures, videos, media and removes encryption on internal storage) got this errors:
Code:
Could not mount /data and unable to find crypto folder.
Failed to mount '/data' (Invalid argument)
Unable to recreate /data/media folder.
Unable to mount storage.
Unable to mount /data/media/TWRP/.twrps
Failed to mount '/data' (Invalid argument)
After this errors i flashed ViperOS, but after first boot it, first thing viper OS ask me was the phone password, after i enter it, the phone show up a message saying that password is ok but data is corrupt, restarting and trying to fix my phone without success (same errors like failed to mount /data)
Also i tried to use the "repair or change file system" selecting Data partition, twrp show me this: http://oi65.tinypic.com/2prin8y.jpg, also i got this errors:
Code:
/sbin/fsck.f2fs /dev/block/mmcblk0p54 process ended with ERROR: 255
Unable to repair Data
What should i do?, i don't know is related with an encryption on data partition, or if this can be solve.
EDIT:
Found the solution in reddit: www.reddit.com/r/AndroidQuestions/comments/7w5c75/used_the_format_data_option_in_twrp_recovery_on/
Just fixed the issue after making a second format in TWRP ( WIPE > FORMAT DATA)
