Missing files on sd card

hey guys, when i try and update my recovery through terminal emulator I get an error
after the line
"mount -a"
i get:
mount: mounting /dev/block/mmcblk0p2 on /system/sd failed: No such file or directory
mount: mounting /system/modules/modules.sqf on /system/modules failed: No such file or directory
mount: mounting /system/xbin/xbin.sqf on /system/xbin failed: No such file or directory
What is wrong here? it seems as if my sd card is missing files?! Can someone give me the files i am missing or would an sd card reformat fix it?

The first error means you don't have an ext2/3/4 partition and you should be fine
The second and third are common errors and don't really mean anything
Just continue flashing the recovery

alright cool, i have now got the new amon recovery!

factory.zip to mmcblk0p3

I am pretty sure my factory.zip is corrupt or nonexistant from my mmcblk0p3. How do i move the factory.zip file over there from this thread http://forum.xda-developers.com/showthread.php?t=919353
Thanks

I just did this last night. First I booted into clockwork recovery and hooked up the nook to my computer and started up adb. I tried doing this when it was booted normally but I could not mount mmcblk0p3. Anyways once you are in recovery mode go to where adb is installed. Then these were the commands I did
Code:
adb shell mount /dev/block/mmcblk0p3 /emmc
adb pull /emmc/factory.zip factory-1.0.0.zip
adb push factory.zip /emmc/
The second line is me backing up my old 1.0.0 factory zip, just in case things went bad. Then I did the 8 failed boot reset and then reset /data

Thank You! I had something like that except i was missing emmc in the first line and i couldn't figure out why i couldnt mount mmcblk0p3. I want to make a how to once i reach 10 posts on this.

Hate to bring back an old thread, but, no matter how I have tried, I cannot mount /dev/block/mmcblk0p3... I always get invalid argument error... any help is appreciated.
>adb shell mount /dev/block/mmcblk0p3 /emmc
mount: mounting /dev/block/mmcblk0p3 on /emmc failed: Invalid argument
I have yet to be able to mount mmcblk0p3 to copy factory.zip to it.... hoping this would fix my install failed error on the 8 failed boot install.
NM.... fixed it... had to mke2fs /dev/block/mmcblk0p3 before I could mount it... got it fixed... the 8 failed boots works as it should again.

complete linux errors ???

Hello I'm trying to get complete Linux to work with our Razer but when I try and boot one of the images I get checking loop device... FOUND
mount: mounting /storage on /data/local/mnt/external_sd failed: Invalid argument
No user defined mount points
net.ipv4.ip_forward = 1
chroot: can't execute '/root/init.sh': No such file or directory
Shutting down Linux ARM
umount: can't umount /data/local/mnt/external_sd: Invalid argument
I need help getting this to work tryed editing the bootscript.sh can't get it to work

Phone won't accept decryption (FDE) password anymore.

My device: HTC One M7 Android 4.2.2, S-ON, Root, CWM recovery (years old version)
My ultimate goal was: Get xposed framework. Install via app failed after rebooting due to S-ON, so I wanted to install through recovery. (this is irrelevant to the issue IMO)
What I tried to get there: Decrypting my /data partition in adb (because CWM doesn't support it)
What I found: https : // forumDOTfairphoneDOTcom/t/how-to-mount-encrypted-data-in-recovery/25724
Everything(!) I actually did: (commands after $ means executed on host machine (ubuntu), prefixed by ~ # means run on phone in adb shell)
$ adb shell
~ # setprop ro.crypto.state encrypted
~ # vdc cryptfs checkpw "<wrong password>"
200 0 1
~ # mount /dev/block/dm-0 /data
mount: mounting /dev/block/dm-0 on /data failed: no such file or directory
(( a couple commands like ls and cat to find out what my /data partition should be ))
(( ended up finding out in fstab that it's mmcblk0p37 ))
~ # mount /dev/block/mmcblk0p27 ((accidentally wrong one))
mount: mounting /dev/block/mmcblk0p27 on /data failed: Invalid argument
~ # mount /dev/block/mmcblk0p37
mount: mounting /dev/block/mmcblk0p37 on /data failed: Invalid argument
(( notice i entered wrong password ))
~ # vdc cryptfs checkpw "<right password>"
200 0 2
~ # mount /dev/block/mmcblk0p37
mount: mounting /dev/block/mmcblk0p37 on /data failed: Invalid argument
(( a couple more tried of the previous two commands for no legit reason ))
~ # mount -o rw,remount /dev/block/mmcblk0p37
mount: mounting /dev/block/mmcblk0p37 on /data failed: Invalid argument
(( exit adb shell ))
(( execute $ adb remount )) (( as google suggested (on host machine, not in adb shell obv) ))
$ adb shell
~ # mount -t ext2 /dev/block/mmcblk0p37 (( accidentally wrong fstype ))
mount: mounting /dev/block/mmcblk0p37 on /data failed: Invalid argument
~ # mount -t ext4 /dev/block/mmcblk0p37
mount: mounting /dev/block/mmcblk0p37 on /data failed: Invalid argument
~ # mount -t ext4 /dev/block/mmcblk0p27 (( why not? ))
mount: mounting /dev/block/mmcblk0p37 on /data failed: Invalid argument
~ # exit (( i got frustrated ))
Before I did all this the phone was working normally (after install xposed via app (which gave me xposed version 3x because I had that one previously installed via receovery. But I wanted the newest (5x) so I went all that way)). After I did all these steps - which to me are readonly things which shouldn't brick anything - I got frustrated and wanted to give up, so I rebooted. Now everytime I enter the - 100% correct - password, it tells me to "try again" (guessing it means wrong password? idk).
The whole xposed stuff is irrelevant in my opinion, because after I've installed it using the xposed installer (APK) I rebooted twice and decryption worked fine both times.
What the hell have I done (I'd say I'm a linux expert and I honestly don't see how I could've possible broken anything by what I did) and how can I fix it?

UPDATE: I got myself the cryptheader from the "extra" partition using the read_emmc vulnerability. That way I got the encrypted key and salt. (cryptheader)
I then used this and a modified bruteforce script to check if my right password is still right. Result: It doesn't seem so.
My password contained special characters and was 15 chars long, bruteforce is not an option.
Is there anyway what I did could've changed the password? If so, can I reproduce and get the new key somehow? The cryptheader is not corrupted and still intact. The /data partition (encrypted) is not corrupted and still intact. (I assume this because the encrypted partition's hexdump starts with "This is an encrypted partition", which is a HTC easter egg.)

I'm far from being a linux expert but the simplest would be to factory reset using htc's recovery to remove /data encryption and start from scratch (unless you have some really important data that must be saved from your /data partition)

I have decided to give up on trying and did a "factory reset" (formatted /data and /data/sdcard through CWM, rebooted, set up device for first use, formatted /data again through CWM to result in clean system).
Fun-fact: Before I did what bricked the system I actually made a backup. The device (µSD-Card) decided to go corrupted filesystem though. I managed to recover most of the files but the /system partition backup (which might have saved me) remained corrupted. I was able to restore all my personal data though, so doing a factory reset wasn't that bad for me.

Data recovery, how to mount messed up /data - Internal SD - sda25 in Recovery/ADB

Hi:
I've messed up my Note 9 pretty bad, such that no partitions mount in TWRP except cache - I'll need to do a data wipe, but I need to save data that I have in the Internal SD.
I've discovered via fdisk in TWRP that the media part - the Internal SD is partition sda25 - however can
t mount it in the terminal through a simple: mount /dev/block/sda25 /mnt
I get an error: mount failed: Invalid argument
I've tried: mount -t sdcardfs /dev/block/sda25 /mnt
This gives me also an error: mount failed: Not a directory
Mounting with -t vfat or exfat gives the Invalid argument error.
Anyone can help me with how to mount it, so that I may copy data off of it manually? I don't want to lose it. Many thanks.

cant you simply wipe the affected partitions(except data of course)? then flash a rom?
have you tried;
mount /sys/block/sda25 /mydata
or
mount /dev/block/sda25 /mydata
or
adb
mount -o rw /dev/block/sda25/data /mydata
in both cases /mydata is just the mount point so I believe it can simply be called what ever you want including just /data
have you read:
https://android.stackexchange.com/q...data-partitions-in-recovery-mode-in-adb-shell
edit:
by any chance when you first flashed twrp, did you forget to format data?
if yes then flash back stock AP file(original phone's firmware) in Odin AP slot only and you should be good to go.( you shouldn't loose any files in internal storage)
