Guys,
I dont know what I did but I can no longer do a factory wipe.
CMW says "Error: Can't mount /sd-ext" Ive tried reformatting / repartitioning the sdcard. it just keeps saying cant format.
I tried CWM 2.5.1.2, then i even flashing it again and tried a 3x version of CWM.
I just wanna be able to flash roms again. Please help
ANY HELP / SUGGESTIONS IS APPRECIATED.

Hey, there are a couple of threads that talk about
"Error: Can't mount <something>" ... you should check them out. I also recommend doing a search for "Cant' mount" you will find a lot of threads talking about a related problem.

Also. it seems i have 2 different CWMs. 2.5.1.2 when i flash into recovery from ROM Manager and 3.0.x when i go into recovery manually.....how is this possible and how can i fix this?

you shouldnt need to mount the external sdcard in CWM. you flash things from the internal sdcard

when i try to wipe data to flash a new rom it says
"
Error: Cant mount /sd-ext/
Skipping....
Done
"
im unable to wipe data so im currently unable to flash anything

thats completely normal.
wiping data has nothing to do with flashing anything.

CWM is unable to mount the sd-ext on our phones because it has a different location (sdcard/ex-sdcard) than most phone (mnt/emmc)

Can't turn on my phone

Hey there,
First let me explain what happened.
I had CM10 installed on my device and last night it kept on restarting and never getting to the bootloader so I first tried to reflash cm10 but the same happened. I had a cm9 backup on my device and tried restoring that but no luck there either. same problem. Then I decided to flash the phone back to stock and work my way up from there.
I opened odin, loaded the pit, pda, phone and csc files and hit start.
Odin showed me the green light with pass but my phone does not load. It enters recovery just before it was supposed to start booting.
I get the following message with the respective colors:
-- Copying media files...
Successfully copied meida files.
-- Deleting files...
E:failed to mount /data (file exists)
E:delete_data_files:Can't mount /data
your storage not prepared yet. please use UI menu for format and reboot actions.
--Updating filesystem...

already updated filesystem. finished
Successfully updated filesystem.
--Wiping cache...
Formating /cache...
Cache wipe failed

So can anyone help me? Please?

[Guide][Script]How to increase the Internal Memory

HI ! In this tutorial i am going to show ya all How to Increase the Internal Memory on SGA GT-S5830i.
This tutorial is not my work. I have taken other tutorials and made one full. As many people were a bit confused about doing this , here it is the all in one tutorial
What do you need :
- CronMod Script
- CWM
- Brain
- Latest Rafael.Baugis Kernels
CronMod Script by Styrke link : http://forum.xda-developers.com/showthread.php?t=1955422
- Now download the "Cronmod Unofficial by Styrke" from the thread ( I strongly recommand it , not the other versions because it doesn't lag and GPS works )
- Place it on SD Card after 1st step [ Partition SD Card step ]
Now we are going to make a partition to the SD Card so backup all your SD Card before doing this ( It formats it )
ClockWorkMod Recovery link : http://www.mediafire.com/?a4j6zsoyaihhy60
- Place it on SD Card after 1st step [ Partition SD Card step ]
Link2SD : Link in PlayStore ( Download when it's time to download on the installation steps lol :silly: )
OK , Let's start now :
Partition SD Card :
1) Open CWM Recovery
2) Go to "Advanced"
3) Select "Partition SD Card"
4) Choose your SD-ext size (if you’re using a 2Gb SD card, choose 512Mb. If your SD card is 4Gb or greater, you can choose 1024Mb)
5) Select "0M" Swap.
6) Wait for the procces finish.
7) Reboot.
8) Now download Link2SD from Playstore.
9) Open Link2SD you will be prompted to choose between ext2, ext3, ext4 or FAT32.
10) First , Choose ext2. If it don't work then restart Link2SD and when then don't choose ext2 but ext4. ( Don't worry , it works )
11) It will say mount script created. Reboot your phone now.
12) Open link2sd and if the message doesn’t show up, you succeded.
13) Go to Link2sd>Settings>check the autolink.
14) To check your memory, select “Storage Info”. This will show you the current state of your internal memory, FAT32, and ext2 partition.

Click to collapse
Placing the 2nd partition of SD Card to internal.
15) Now your SD Card is formated .
16) Place the CronMod Script on your SD Card ( Cronmod Unofficial file )
17) Open CWM again
18) Foramt /data /sd-ext /system
19) Mount /system
20) Flash custom rom
21) Remount /system
22) Flash "Cronmod Unofficial " script.
23) Reboot
Click to expand...
Click to collapse
Alternative mod : If you have already your custom ROM just do these easy steps :
1) Format /data /sd-ext
2) Mount /system
3) Flash "Cronmod Unofficial" script
4) Reboot
Click to expand...
Click to collapse
NOW YOU SUCCESFULLY INCREASED YOUR INTERNAL MEMORY
How to delete 2nd partition and revert to normally :
1) Go to CWM
2) Go to Mounts and Storage
3) Choose " format /sdcard "
4) Done
Click to expand...
Click to collapse
Note : Backup everything again or you will lose every app installed on 2nd Partition too.

any thing other than mini tool partision wizard ??

is this to download?
Data2sd-ext Fixed.zip
As the other one is not there

No no ! No tool needed and what do you mean to format it ? Ah, if you mean the 2nd partion just format/wipe the /sd-ext on the mounts and storage on CWM . But it is unnessesary becouse the 2nd partition is transfered to the the internal memory.

recommend fresh rom... rom with lot of appk maybe bootloop...no need link2sd... easy way, flash rom, flash kernel(boot.img & module) mount system & flash cronmod unofficial by styrke(latest script).. done... depend of what rom, maybe no need to mount system... kernel also, no need flash if rom include lattest kernel...:silly: adios...
#remember, create partition with cwm its totally format your sdcard... before do this, save data sdcard to pc/laptop... only left behind cwm.zip... when done, move back saving data to sdcard... when all its ready, happy flashing lol...

Hey I followed your whole procedure,
but I got stocked when I wanted to apply the data2ext-fixed file
During my stock rom, I had partionated my sd-card on windows computer, not with CWM, but after I used ur guide, I partionated it again with CWM, so now it should have the structure given by CWM, right?
But here is the problem. In CWM I don't get the option "Format /data /sd-ext" there are just the following options: format "/data or /sdcard or /system or /cache" but no option "Format /data /sd-ext"
So might it be that CWM didn't apply the extention right?
When I open Link2SD it does all the things it should do, but the internal memory is rising, so maybe it is not putting the files in the right place, someone said instead of putting them to "sd-ext" it is putting them to "sdext2"
Another point: In the tutorial u mentioned after step 14)
"Placing the 2nd partition of SD Card to internal." Is that a point I have to do?
Because right now the 2nd partition is sdext2, but it is still not preventing that the internal memory is rising.
Hope u can help me to solve this problem.

LOL. Of course there is no such option like Format /data /sd-ext. What he mean is format your data and sd-ext one by one. Meaning you should format data 1st, After finished format sd-ext.
And for your second point problem, it is a title. Not a step to follow.

Ok, but in CWM there are only the options "format data" and "format sd-card" so in this case "sd-card" and "sd-ext" is the same?
Because I don't want that the ext3 which i partitioned before will be deleted and the sd-card will only consist of one partition and not "sd-card" by itself and "ext3" part on the sd-card.
If i push "format sd-card" it will not destroy the partitions which i created before?

LOL , data2ext script is only for ext2 first and you should go to mounts and systems and format /sd-ext and data as i said in the instructions . If you can't see any , buy some glasses You haven't seen correctly ! Follow d steps carefully. It's a bit complied so you should keep an eye to the thread and an eye to the phone .. And yes if you format /sdcard your partition will revert back , so you will uninstall it

So yeah maybe the CWM version I'm using is outdated.
So let me ask this
in this thread there are some files to root and also have CWM.
My phone is rooted, so which file (i think they should be most up-to-date CWM-files, right?) should I download and use for CWM?
http://forum.xda-developers.com/showthread.php?t=1551156
So another question, so you said the partition should be ext2 not ext3, otherwise the data2ext script doesn't work, right?
I think I can't see the "format sd-ext" option, because my CWM is outdated, which version should I install? Where is the link for the most current- or usable version? Should I get the ClockWorkRec_S5830C-i-M.zip from the thread mentioned above?

[Q] Restored to Factory with Odin; still won't boot

HI, all,
My phone was kind of unstable for a while, with lots of error messages saying "this app needs to close." Last night the battery died during the night, and when I replaced it with a charged battery and turned on the phone, it would only boot to the devil kernel screen, then it would stop. I spent hours reading on the Internet and in these forums, and it seemed my best bet was to restore to stock via instrux on this thread: http://forum.xda-developers.com/showthread.php?t=731989
That seemed to go well, but at the end the phone didn't reboot like it should have. I get to the At&T screen, then the phone shuts off. Not only that, I can't even get into recovery mode now. I don't know what to do now, and I honestly can't understand most of the lingo in the threads to know if there's already the instruction I need out there. I'm sorry to ask you all to repeat yourselves. I'm totally new to this. Please help.
The phone had been rooted and had devil kernel and CyanogenMod 10 (i think). It was running a version of jelly bean that was out on this site in August. That's all I know (ex-bf rooted it for me). Any advice is much appreciated!!!

Try 4-2ndtwin's one click Odin stock kk4 ROM. Maybe without bootloader version, assuming you haven't lost the GB bootloader.
http://forum.xda-developers.com/showthread.php?p=18370912
You will need to get into download mode. There are stickies in this forum that tell you how to do that.
Designgears thread won't help you, I think. It's pre-gingerbread.
If you can get to KK4 ROM, then flash the Corn 7 kernel with Odin, then you will have CWM recovery and can flash the CM10.1.0 RC-2 ROM which will be better than what your bf had available in August.

Thanks for this advice. I flashed the Odin kk4 ROM, and now I get the GB bootloop. Might that mean that I need the bootloader after all?
EDIT: When booting, my phone was also flashing colorful, scrambled-cable-looking screens. I found another thread in the forums where someone had this issue, and the response to that person's query was that the person needed to flash the bootloader. So, I went back to the link you gave me and got the version with the bootloader. I flashed that, and now I still have a bootloop, but it loads a couple of more screens. The colorful screen is gone. Any suggestions now? In reading other threads, it seems like there are a few options. I'm not sure which to go with.

It involves setting up an external SD card to act as an internal one by partitioning the card through CWM. I have no idea how to get into CWM. Maybe I'll still play around with it to see if I can salvage something, but I think I'm going to get another phone to use at this point.

[Q]Wiped clean to install rom, now can't access sdcard

Hello.
first I want to apologize for my, sometimes, bad English!
Second, i want to apologize for my novice touch in this topic!
The story:
I've been using SweetRom for a while, but tonight i wanted to try another rom.
I loaded up SuperBean(not really relevant to this story) on a microSD.
Rebooted my phone into recovery
Philz Touch 5
I choose "Wipe Data/Factory Reset" and then "Clean to install a new rom"
Then i tried to "install zip"
"Choose zip from sdcard"
But then i get: E:Can't Mount /sdcard/
I've tried to format the sdcard, exfat, fat, fat32, ntsf but nothing worked, still the same error.
I can access the internal storage and i can boot into download.
I thought that maybe i'll try to install the newest Philz but when in download mode
my computer wont recognize my phone (i'm using Windows 8)
i'm stuck! please help me out!
I've searched everywhere for answers but i can't find any!
What are my options?

Boot into Philz recovery again and go to mounts and storage and mount USB. Then connect it to pc. Check if the any drive shows up. Then move the new rom to the internal storage.

is /preload equivalent to /dalvik-cache? but then what's the point of format /data/factory restore if "clean to install new rom" is present?

No. It's different. Preload is a separate partition and dalvik-cache is in data partition.
The option you mentioned only exists in Philz recovery not in standard cwms

is /preload equivalent to /dalvik-cache? but then what's the point of format /data/factory restore if "clean to install new rom" is present?

No. It's different. Preload is a separate partition and dalvik-cache is in data partition.
The option you mentioned only exists in Philz recovery not in standard cwms

So, to be clear, is it necessary or advisable to do any of 'Wipe Data/Factory Reset', 'Wipe Cache Partition' and 'Wipe Dalvik Cache'? Or is 'Clean to Install a New ROM' merely an amalgam of the above (plus added formats?)?
Thanks

It's usually not necessary but it is ALWAYS advised to format /data /preload /system and cache before flashing a new ROM. If you don't do those wipes then you can sometimes end in a bootloop, random force closes, battery and performance issues et cetera. Basically if yoou want to flash a new ROM (unless it is an update to your current ROM) then always do a full wipe,
If you are just updating your ROM (ex. updating one nightly to another) then you just have to flash the ROM in recovery and wipe cache, dalvik cache (in advanced)

Thanks very much for that - much appreciated.
I've read elsewhere that many seem to recommend wiping cache and dalvik after they've flashed a ROM? Is this something you'd advise and, if so, why (or not!)?
Many thanks

If you're updating then yes, it's enough that you flash the ROM and then wipe cache and dalvik cache.
If you're reflashing from start then you should first do a full wipe, flash the ROM, gapps, su and that is all. No need to wipe the cache or dalvik cache again

Ah right. So if you're flashing a new ROM - then clean install is all that's necessary. If upgrading to a newer version of existing ROM, then it's better to wipe cache and dalvik post-install? Why? What does it do and how does it help?

reset before installing zip, now no super su ... cannot mount usb
Hi,
The title says it all. I have been reading and searching. Many similar stories. I apologise if this is in the wrong place but this is very similar to my problem.
I have a galaxy i9505 trying to install a DjeMBeY ROM from TWRP.
I factory reset and wiped cache's BEFORE I flashed the .zip file so then had no .zip file to flash!
Also have erased my system backup and the USB WILL NOT SEEM TO MOUNT to copy it back onto the card.
I have read and read I am very struck.
I am not familiar with all the processes yet. Please help.

i recommend going to here

Similar prob

Boot into Philz recovery again and go to mounts and storage and mount USB. Then connect it to pc. Check if the any drive shows up. Then move the new rom to the internal storage.

You can go with the download mode and install a stock ROM or use the 'adb sideload " feature of cwm recovery to install the zip of your ROM if you have it saved on your PC.
