[Q] Backup problem using CWM recovery mode - Galaxy S II Q&A, Help & Troubleshooting

Hi, I have a question about the cwm recovery mode (zip file).
My phone is Galaxy S2 with android 4.1.2 (I remember it should be) but I can't boot into android. I only can boot into "Download mode" and "Recovery mode". I want to back up data (eg. photos) then reset factory setting.
I found "CWM recovery" has a function to backup and restore the phone data. I tried to use it by installing update from sdcard.
Then I backed up things. However when I read the sdcard through PC, there is nothing except the recovery zip file.
Then I tried to backup again, it said
"SD card space free: 0MB"
"E: unable to open ums lunfile (no such file or directory)
After some investigation, I found my GS2 RECOGNIZED some of the INTERNAL STORAGE as SD CARD to do the tasks above.
How can I instruct the phone to "know" my real sdcard...and then I believe I can do the backup correctly. I know that the phone data is still here.
Thank you in advance!!

[Q] Can't do anything from the CWM recovery menu

When I'm trying to do a Nandroid backup I get this error:
"Can't mount backup path."
and when I try to flash a custom ROM (Cyanogen 7.1), it says:
"E:Can't mount /sdcard/"
I searched a bit, only found people having problems with a certain boot loop. I don't have that problem. Just can't do anything from CWM recovery menu.
Anyone who has a suggestion? Thanks.
edit: i just noticed a similar topic about this under this one :x
edit2: seems it worked when I tried to backup on the 'internet SD card', gonna try to flash it that way too.
Hello,
I am getting the "Can't mount backup path." and I don't know what to do now. Also, FWI, the first time I tried to backup, it started, and few minutes later, it stopped because lack of memory, so I switched to a bigger SD card and this is where I am: Can't mount backup path.
If I go to the "mounts and storage" menu, I can mount everything but the /sdcard.
I don't know what to do. I'll keep googling, thanks.
Have you tried backup to internal sdcard? (4th option, if present)

Oh, that's it!
Thank you very much!
That's what sebas156 meant by "internet SD card" (LOL), the internal one.
Thanks again.
Also, I've read several problems on google with the "Can't mount sdcard" error, should I be worried?
Thank you SO MUCH!!!
I also had the problem with "can't mount backup path" and I thought that it was a CWM problem. Was thinking of making a new topic, but apparently I wasn't the only one who had this "problem". This topic made things clear.
Thanks!
Can't mount backup path - I want to backup to internal memory
I am using CWM Recovery 5.5.0.4 on a Galaxy Tab 2 GT-P3100.
The phone is not rooted. Do i need to root the phone before backing up?
I am getting an error - Can't mount backup path every-time I try to backup.
I do not have an external SD card. I want to backup to internal sd card.
I don't have the 'supposedly 4th option' to backup to internal memory.
Is it because this version of CWM does not have that feature?
I went into 'mounts and storage' and could mount everything except '/sdcard'
Kindly help me out here.

you are currently in the galaxy s2 section, if you have a galaxy tab, go to that respective section to find help.
also, how did you get cwm without root? and now you want to create a nandroid backup?
are you sure you know, what you are doing? no offense, but it is important that you do or you might seriously harm your device. also, you should not flash anything from this forum section, as it is meant for another device and will brick your tab.
CWM
I'm getting the same error.. I tried Internal SD card also, but it won't allow me to back up my stock ROM

Rom Manager with CM7

Does this work on the Nook Tablet? Mine doesn't appear to function when I try to do a backup.
ROM Manager
I am using ROM manager on CM7 alpha12 without problems. I use it to boot to CWM recovery and back. I use TB and CWM for backup so I can't verify backup with ROM manager.

So you are saying that you did the newest CM7 upgrade and your CWM works without using a SDcard? When I try to do a backup in ROM Manager my tablet will reboot and then it comes up with a screen saying to power cycle again and if this don't fix it call B&N support
ROM manager
Correct - if I want to use CWM I just start THE RM app and select to reboot to recovery. The tablet reboots into cwm and I do what I need,for example,backup and repartition data and media then select to reboot to regular CM7 ROM w/o changing SD card.

Bummer Mine doesn't work and I have no idea how to fix it
I cant do a backup directly from ROM manager either.
BUT if you follow his directions and boot into CWM first, you can do a backup from there without a hitch.
If you want to name it yourself you need to go to the file in your file manager of choice, and change it there.
Can someone tell me where backups to internal storage are stored?
Thanks.
sdcard/clockworkmod/backup
I do believe you need a sd card for your backups.
It sounds like you do not have one, thats why you are not able to do a backup?
I have one and it creates a backup via internal. But when I try to backup to sd card, it tells me it failed to mount. So I backup via "internal storage." I can then go to restore and I see my backup from the internal there.
Dont have my tablet in front of me but it somehwere like: /mnt/emmc/clockworkmod/backup
You should find a clockwordmod in that general area if its like CM7 for other devices
You can manually mount and unmount your SDcard through clockwordmod as well. Have you tried to mount it manually before backing up
I just decided to try it again, booted into CWM and clicked "backup" and now its backing up to sd (free space showing as 30017MB, 32gb card so that makes sense).
Earlier when I tried manually mounting the sd card it was giving me an error (failed to mount). I have no idea what fixed it but its working now and I'm sure I'll be able to find the sdcard backup at the very least.
Thanks for your help.
The SD card doesnt always mount on its own in these devices. I HAVE noticed that..
Hell,it doent even want to mount with guidance, as you have just shown, and I have experienced as well..
Glad it worked this time..
sd mount
As has been noted in other threads, sometimes you have to take the card out and reinsert to get it to mount. I have had times when using the CWM menu option to mount sdcard failed. Turn the tablet over,click the card out and back in and it will mount

Definitely the case, but when in CWM it doesnt always mount even by ejecting and re-inserting the card.
At least from my experiences.

[PLEASE HELP] I formated /system and can't restore

Hi, I was installing a ROM and I formated /system and rebooted but the ROM didn't work it repeatedly said process android sopped or something like that, so I rebooted to CWM recovery and was going to restore from my external SD card but there wasn't an option for that there was an option to restore from internal SD card but it said no files found so now i'm in cwm recovery and when I try to reboot the samsung logo appears and disapears constantly and nothing happens. The CWM recovery version is 6.0.4.4. I have the restore file on my PC. Is there any way I can send it to internal SD card? I can't access it even on my computer because the phone isn't fully booted. Please help me
My phone is Samsung Galaxy S2 and PC is Win8

[Q] Format EMMC by mistake - Please help!

I am a complete noob and got my lesson for messing up with my phone. I have an already rooted SGH i777 and was trying to flash OMNI Rom for 4.4. I wiped emmc by mistake. Although I did back my stuff up, they are no where to be found.I get cannot mount SD card error through CWM v6. I read somewhere that this is resultant of having no operating system in my phone anymore.
My phone is not recognised by computer. But I can access an external microSD card while booting recovery using CWM. Please help me as I am completely lost without my phone. You patience is deeply appreciated.

If that's the case, you should be able to put a rom on the micro SD card and simply flash it in recovery. You may have lost your backups, but if you can flash a rom via the SD card you ought to be fine.
Let us know if you need any more help,
sent from the i777
I'm not clear what you mean by "I wiped EMMC." Can you please describe exactly what you did, and describe the options you used if it was through recovery, which I assume it would have been.
If you put the phone into download mode while Odin3 is open on the desktop, does Odin3 recognize the phone?
FYI: TWRP file browser sees internal memory as "emmc". From the advanced wipe menu of TWRP, exists the option to wipe internal memory.
edit: really annoyed that I am limited to eight thanks at a PC, which has a much more comfortable interface than the XDA app, where I have unlimited thanks to offer my peers.
This is what happened
Dear all,
Thank you for your help. This is what I did. I tried to install Omni ROM for 4.4. I I downloaded the .zip file for the ROM and Gapps package zip and SuperUser zip. I went to CWM based recovery mode and wiped data/factory reset and wipe cache partition and in advanced wipe dalvik cache.( I did not run any wipe script as mentioned in this forum. I would have avoided all this if i actually paid attention and read the correct way of flashing here.)
I then went on to mounts and storage and did format/cache , system, data and preload. But also format /emmc
After that no ROM could be flashed and I could not access any recoveries. I realised my error when I saw the log that No files are found and couldnt open directory.
Update :
My phone is not recognized by Odin v1.85 and I also put a SAMSUNG_UCLE5.zip for SGHi777 given by a friend on to a microSD card and tried flashing that ROM from external microSD.
The log says:
I:Can't partition unsafe device: /dev/block/mmcblk1p1
I tried to partition just to see if it works. This time the log says
I:Can't format unknown volume :/external_sd. I never had an external sd card, but I gather that the system was partitioned in such a way that one chunk is considered external_sd.
Odin doesnt recognise it in download mode. I tried every USB port, changed data cables, tried different drivers available on Samsung website.
Please tell me I didn't ruin my phone. Any help is deeply appreciated.

This is beyond my level of understanding. I'm not sure what block 1p1 is. All of the partitions are designated as 0px where x is a number 1-15~.
I assume you've tried all the variables to get Odin to recognize the phone in download mode. Since Odin doesn't recognize download mode, I don't know of anything else to do but send it to someone with jtag equipement. It'll cost you maybe 40 or 50 bucks, but at least you can get your phone back. The person most trusted in the forums here for this sort of repair is Josh at Mobile Tech Videos.

Galaxy 3 SM-T2105 Kids Tablet stuck in CWM Recovery mode, 4.1.2

So, I screwed up my kid's tablet trying to allow for more than just in-device storage because Samsung gave it a Micro SD port that it can barely use.
Anyway, I used Odin to install <recovery.tar.md5> from Zip folder: T210.CWM.6.0.4.5.recovery.tar
I had tried installing T210.TWRP.2.8.0.0.tar.md5 but could not get a successful restart.
This is the instructions I followed: (Ooops! Can't post outside links, yet.)
Installed Samsung USB Drivers and enabled USB debugging. (Had issues getting all the drivers to install. But had no problems with Odin).
Copied android-armeabi-universal-root-signed.zip to the SD card on the tablet.
Sent CWM recovery file via Odin.
Rebooted into CWM recovery
Installed from Zip on external SD
Rebooted again as "Android updated"
Initial Root check said not rooted, but downloaded SuperSU by _______? (can't tell at the moment) And then it came as rooted.
Downloaded App2SD and partitioned the external SD card. Had to use Format option instead of Create for it to work.
In APP2SD, selected something about Linking apps. A prompt came up stating to reboot into recovery and do 2 things which I quickly forgot.
Rebooted into CWM and have been stuck ever since.
Attempts to turn off the Tablet end up in a restart into CWM. I did discover that if you press and hold the Power button and the Home button, it will force a shut down, which gave the screen a rest.
I've used most wipe options in CWM, accept the dalvik cache.
When I choose "restore from /sdcard," the image "2017-08-22.16.41.29" results in "Checking MD5sums... MD5 mismatch!"
I was able to remove the MicroSD and add the android-armeabi-universal-root-signed.zip folder back to it. However, after installing this zip successfully in CWM recovery, it just reboots me right back to CWM.
In this adventure, I have used ADB to re-flash CWM but nothing changed. I'm brand new to all of this as you can tell.
I need to get this tab back in working order. What do I do?
CWM recovery gives MD5 mismatch on restore
OK, got a TWRP to work (T210.TWRP.2.8.7.0.tar.md5). Now, I at least have a factory reset, working tablet.
But there is still a backup file from CWM, right? The "2017-08-22.16.41.29"that results in "Checking MD5sums... MD5 mismatch!"
Any chance I could fix this error and get back some or all of my missing stuff?
Wrong forum im afraid...
Ever considered flashing stock firmware with Odin?
Read up on it Itll solve most of your issues
Which is the correct forum, then?
What I really need to know is how to link apps to my SD card. Or some other procedure that allows me to use SD as internal storage.
