SD Card Error Message

Code:
[B]E:unknown volume for path [/sd-ext] [/B]
This is the error I get using Revolutionary and am flashing a new rom using the 'correct' method spoken of here.
This error message occurs after I've wiped Dalvic Cache. The phone still performs as normal without any issues. But I'd like to get rid of this error if i can.
Can anyone help with this or has anyone had or seen it before?

Try re-formatting the sd-ext partition using 4EXT recovery. Failing that, backup your entire SD card contents and re-format the whole thing, then copy your files back. I had a 512MB EXT3 partition on my card for ages from my old Desire days and A2SD+ ROMs. Never got your message but that's what I would try.

Isn't that SD partition? I also have that (when flashing, or doing backup) and I thought it was normal coz I don't have partition of my SD.

Thanks for your answers guys.
@wnp_79 I always format my sd card when i flash a new rom.
@MarlIX I'll try formatting again and making a partition using the whole sd card size to see if it solves it.

I guess that it depends on situation in which you're extending main partition with SD card (as HTC Desire users have to do in order to install ROM which doesn't fit on internal memory). In normal cases you'll have such warning because you don't have extended partition on SD (But someone please correct me if I'm wrong)

ah ok so i shouldnt worry about it then really unless the rom i want to flash requires extended partition?
I can make a partition on Revolutionary i get these options 128m,256m,512m etc etc and then i brings up a menu saying swap size 0m,32m,64m,128m or 256m.
Any guesses on the best way to set my card up?

If you are not using it then use either choose the smallest size, our use 4ext recovery to remove it.
Whenever i did it, a 0MB swap was just fine.

I see an option to remove all partitions and start from scratch so next time i flash i'll select that and maybe that will sort it out.

[Q] apps on my sl force closes and data does not get formatted please help

my galaxy sl does not get formatted and system apps and downloaded apps force closes i have tried wiping data,cache and dalvik cache but the problem is not solved.i have even tried flashing xxkpe and then ddkp3 but its of no use.the problem is not getting solved.i have even tried to flash cm9 and remi ics trough cwm but its gives me the message Encryption unsucessful.please help somebody.i have searched on xda but didnot find any such problem so started a new thread.please help

what do you mean not formatted? Was it the sd card? If flashing a stock rom does not solv the problem "i think" its your sd card which causes the problem. HAve you tried it on different sd card?

by saying not formatted i mean that all the apps which were available before flashing and wiping data remains and i have i tried flashing it without a sd card.so i dont think it is sd card which is causing the problem.can u tell me when do i get a message "Encryption unsucessful" when flashing remics or cm9.

try the below may help you. but you will lost all your data
flash Universal CF-ROOT by amit
reboot into revovery
mount and storage - mount all the partition.
format /data
foramt /dbdata
format /cache
format /system
do not reboot
in advance - reboot download mode
than flash pit file
than flash XXKPE by odin
manual reboot one time
than factory reset
see is you problem solved.

No good bro, the problem is still exist. i faced it too
After flashing stock ROM it says "failed to mount /data (invalid arguments)" and bootloop

@chongns i did all the steps u told properly but still the problem exists.the apps force closes and the data is still not wiped.please provide another solution.

Hi bors if this way not able to slove ur guys problem, than i think ur problem is come from the hardware. Either go to service center or try to make partition in the ext sdcard. Check the thread regarding this problem in here. Follow them.

@Gabuz. Didnt know if this help you. This is a guess.
When flash in odin, check on the option "update bootloader"
There are risky. Cause i did it once when i flash from froyo th GB. but my phone still alive.

@chongns u suggested to format data,cache,dalvik cache and system but there was one more option in mounts and storage (i.e.mount emmc and format emmc)should i have formatted that emmc also.and what was imp of the post u sugested before.

i also formated emmc but its of no use the apps are still force closing and data is not getting wiped.

sometimes after flashing and using the mobile for a while sometimes it goes into kernel upload panic mode.what is kernel panic upload mode and what causes it and how can i not get such a message.please help

i also tried to install miui v4 but it gives the same problem as as remics and cm9 it shows "Encryption unsuccessful"

I would said u having the partition corrupted. So it is wise send it service center than you corrupt it more further

it have similar problem with you, you can have a look

after flashing value pack update for india it shows
E:failed to mount /data(No such file or directory) what does it mean and how to make it usable it is not working.please help

Are u facing a random reboot then you get to 'encryption unsuccessful' screen? Then a reboot would get you back to normal state? I solved this by flashing the value pack via mobile odin pro with ever root. I flashed the latest one by prezket

[Q] Ooops - Tab's funked. Help!

P6800 running Zeta
I was browsing facebook the other night when... shaboom - everything froze. No biggie I thought, I'll just do a little reset (I was getting a few FCs here and there anyway lately) and I'll be good to go...
NOPE. It started bootlooping at the initial Samsung Galaxy Tab 7.7 screen. I'm able to enter CWM recovery and even wipe the cache and flash ZIP files, but when I try to wipe data/factory reset, wipe the Dalvik cache or restore a Nandroid backupI get a System Error. It doesn't look good.
Is there a way to fix my seemingly funked /system without losing all my internal SD card data (where my Titanium backups reside) or to recover it before a full Odin flash?

Just tried again - it reboots and goes into a loop when I try to wipe data and dalvik, and when I try to restore a previous backup it gives me "Error while restoring /system!"
Any help greatly appreciated before it becomes a $600 door stop

Do you dare to wipe the system folder and follow by flashing another ROM?

Do you mean via Odin? Will I lose the data on my internal SD card by doing that? Is there any way of mounting the device in its current state as external storage on my PC to copy all data before a wipe?
ZhenMing: I'm not sure what you mean, but as I wrote above I am not able to wipe the system folder.

yes you will loose your data... i can give you another advice... but do this one carefully... the reason why your device cant wipe any /system or /data is because the corrupted partition... you need to check it... follow the guide in this thread...
USE ONLY PART 3... follow the guide start from this para to check your device...
Code:
Now we are going to use e2fsck to check our new partitions for errors, but not only, it also fixes some erros and it will even for example create lost & found in /data
So let's go, we'll begin with /system. If you're still in the (parted) shell, use ctrl+c and type "adb shell", then issue the following :

Since you can go into cwm, you can mount your storage and then connect to PC to copy all you want.

But won't it downsize the int sd size, if OP tab still under warranty, better to get it fix by samsung for free and not lost any space.

Just reading the 1st post of the ZETA rom thread.
He says he is using stock Kernel.
He says every 5 lines, that you should full wipe...
without giving any sort of warning that it will eventually brick your device.

Tried that one, but it won't mount unfortunately. The external will no problem, but when I try with the internal it just... well it does nothing. It's a bummer cause all my most recent backups are on the internal. Any other way of retrieving my data short of extracting the chip?
Giving it back to Samsung sounds like the best option, but I'm worried cause it has a custom ROM and it's rooted. Anyone has experience doing that?
Also I thought full wipes were good, but you're saying they eventually brick the device? How come? I thought having a custom recovery meant it would be virtually impossible to brick my device... and the weird thing is that it happened during normal usage, not while flashing.
Anyway, my priority is obviously to get my tab working again, but retrieving my internal data is second highest. Isn't there a flashable ZIP that would copy the contents of the internal SD into an external SD card? Surely this has happened to someone before me?
Thanks for all the answers, really appreciated!

nope it wont... the 3rd stage on that thread command for just check and fix the corrupted partition... its like when we force boot windows... it will run on a little diagnostic software to check the drive... same concept.

Gotcha! Will try that one and post result - thanks!

how did your partition check go?
i'm annoyed that some partitions can be corrupted randomly even doing some mundane stuffs
even on stock ICS fw, i encountered DATA corruption by just deleting a contact
i guess you have softbrick..
here is what i did:
-flash stock Honeycomb firmware using Odin
-forced tablet into stock recovery mode
-wipe Cache/Data/Factory Reset
- reboot
when your tab is working again you could backup files from your internal EMMC and you could flash ROMS from there

Thanks for that. I haven't tried anything yet as I'm away till Weds, but I will then and let you know. So you're saying by flashing stock HC via Odin and wiping/resetting everything through stock recovery I won't lose my internal storage data?

that's what i experienced..but i could not guarantee that it will be the same for your device
i noticed that because old folder are not deleted when i rebooted, but i haven't checked if the system folders are cleared
to have a clean reflash i also format/sdcard on recovery..but don't do this on stocl ICS recovery since you might risk increasing the damage
try to format via odin the Honeycomb fw first [don't put PIT file neither enable Repartion, just normal flash]
then force it to enter recovery mode when it bootloops after reset
you might fix your device this way if it has softbrick
just resort to using PIT/repartition as your last option

Again I would not recommend repartition when tab still under warranty. Repartition the last resort only if the tab is without warranty after failing all other alternatives.

[Q] No way out of Bootloop + 'can't open /sdcard/update.zip (bad)' error

Ok..so I've been using HTC explorer for 2-3 months and everything was going fine but the low internal memory kept bugging me so I rooted the phone (i delayed rooting because it voids warranty..)..I deleted the pre installed apps and all other unnecessary crap..but the internal memory was still low so I went for factory reset..:|..and thats how you get into bootloop but searching for solutions..i found that my problem can be solved by flashing new rom..so I downloaded 1 and flashed it (yes i followed all the steps like creating ext4 partition and wiping cache etc).. but suddenly 'can't open /sdcard/*rom*.zip (bad)' popped up..so I went through the forums but didn't found any approved solution but suggestions like re downloading the rom..or checking if signature verification is off or flashing any other rom..i tried all of them..i retried re downloading the rom..I tried flashing cm 9..explode^1..Jaggyrom..even the stock rom but nothing positive happened..I am clueless..Please Help...

What recovery did you flashed, another thing, try with another sd card, or repartiotion this one through recovery after that get some rom on it. If you have a card reader, check if the card is ok.
And don't rename zip's live them with their original names.

i flashed with A310e recovery...and the card is fine..I read somewhere to format the card with sdformatter and flash the rom from there and create the partition after the rom has booted..so i am trying that..I'll update you..thnx for reply btw.. :highfive:

Try installing CM10 Beta 2 on a clean, unformatted sd.
If that doesn't work, change your recovery.

Working fine
everything's alrite now..the thing that was causing the problem was the partitioned sd card...I removed partition and then flashed it and everything went well...:laugh:

[SOLVED] TWRP can't mount internal storage - the problem is coming back...

I wanted to update my rooted Android Nougat to Oreo and also go from SuperSU to Magisk. During that process I discovered that TWRP recovery couldn't mount my internal storage.
I quickly saw on a lot of sites that it's a well-known issue, and I solved it by converting from ext4 to ext2 and back again. Now my phone is running perfect. All apps are installed, data and settings are restored with Titanium and root with Magisk is working fine. But then I remembered about the issue with TWRP and booted into recovery - just to discover the problem is back again. I can't mount my internal storage. So I can't flash zip files, I can't do a backup etc.
When I search xda or the web in general, I can't figure out why the problem has occured again. Also I can't find out how to fix it without losing all my data. Can anybody answer these two questions? Why is this happening again and how do I permanently fix it? And can it be with all my data on my phone - because I'm not able to do a backup.

The problem occurs when you use a ROM which encrypts the software or the ROM your flashing has an encrypted kernal. The only way out is to flash a ROM which doesn't encrypt. It is a known problem with TWRP and we have to wait for the TWRP team to update TWRP to handle quota allocation.

It seems the problem is solved for me. I flashed the TWRP version from this link: https://forum.xda-developers.com/showpost.php?p=77296102&postcount=1243
First I tried from Odin but it didn't work. Then I installed the TWRP app from Google Play and flashed the other file, rebooted to recovery, and it seems to work. I can mount my internal storage, make a backup etc. So this is the solution for me.

I had also similar problem of internal storage 0mb and i was not be able to mount my data
so when i flash color recovery by nobody
It's gone because it's allready patch by him
I think it's issue of encrypt data so just flash this recovery from nobody post

same problem, have you found solution ? please help me

TWRP sometimes can't mount the storage, the storage is encrypted, but don't worry. You can still flash your files and rewrite system partion. But in order to show the Storage, you have to use a different version of TWRP. Why am I saying this is mentioned following:
I installed the latest version of twrp, It didn't ask for any password patter to decrypt my storage. So , different XDA posts made me understand that , formatting everything, factory reset will decrypt my storage. And trust me, I have done it several time, several times my brother but it didn't decrypt my storage. I couldn't backup my ROM and without backing up my ROM, I didn't take the risk of flashing new ROM. I waited. This twrp couldn't even mount my system partion. So I seeked knowledge from different person. It took a lot of effort.
Then I learned that, I should change this version of TWRP. I changed to an older version and it didn't decrypt my internal storage after formatting, but it mounted my system partion. Since, it couldn't decrypt my internal storage, I couldn't take backup of my rom and save it to internal storage. so I inserted a pendrive in my phone, and saved the backup of my rom there.
Permanent Solution​
Flashing DM Verity Force Encryption Disabler will decrypt your storage instantly. But in my case, it aroused another problem, None of the security measures of my phone worked afterwards. FOD, pin, password, pattern none of them worked. I don't know the reason but I don't suggest it with my little knowledge. but almost every rom flasher use them, so I thing I have to study about them to know how they work.​
second and best option: start trying older version of TWRP, the good one will be the one to ask the password the recovery in the beginning. It will decrypt your internal storage.​
I was brief here, if anyone doesn't understand these things, let me know, I will explain them step by step because I know the pain of being NEWB.
