Recovery bug need help

Hey guys I wanted to restore my old backed up data from recovery mode.
So ye I get this error message saying:
E: can't mount/cache/recovery/command
E: can't mount/cache/recovery/log
E: cant open/cache/recovery/log
E: can't mount/cache/recovery/last log
E: can't open/cache/recovery/last log
(something similar can't remember what it said exactly)
I wasn't really bothered about this error before but now that I cannot restore my old data its a bit of a problem.
Any ideas on how to fix this?

Try using FlashTool to wipe your cache

Tried but no luck

Try mounting /cache via the Mounts and Storage menu and then restarting the process.

Doesn't the recovery tool give you the option to selectively restore things? Why not just restore everything except the cache.

ERROR: Format /data

Hi guys i have a samsung galaxy GIO ... i have a problem.
When i try to do format /data or davlik cache , i have this problem:
http://imagebin.org/207052
How to solve? Thank u

Is it rfs+ext4 variant of CWM? I remember switching to extonly after such issues. There's also a flashable ZIP around that formats everything - gio-all2ext4.
You can try.

Hi, i have flashed that .zip but the situation is the same... help please!!!

Maybe you could try v. 5.0.2.6. Everything works fine for me. Further ive no idea what to do :s

its in the cm7.1(!) thread, there you can still download px-cwm-v2.zip, it is v5.0.2.6
here it is:
http://www.mediafire.com/?p7r2bcn9447bpc8
however this version may give problems too, as this is the changelog from cwm v2:
Code:
New CWM v2
special thx to ZimniY
fix error mount command
remove rfs support
but also :
Code:
Based on particle's CWM Recovery, only add ext4 support for system, data & cache
\
but this one is working for me fine too, only sometimes after going from ext4 to rfs it gives problems, then flash 5.0.2.7 with ext4+rfs support..

Hi when i try "wipe data" or "format /data" i recive this error:
Wiping data...
Formatting / data...
Error mounting /data!
Skipping format...
I have tryed restore, i recive
E: format_volume: make_extf4fs failed on /dev/block/stl13
I can replace the file stl13 with that of a nexus S with ADB?
why? i have a CWM 5.0.2.7

Stock recovery and stock ROM are installed when you flash with Odin.
Files and folders in /dev are symbolic - they are created with Linux kernel's and services' startup. They cannot be copied and transferred.
Are you trying to restore ext4-based ROM within rfs+ext CWM? My experience says it's better to install ext-only CWM if you're going back to ext-based ROM.

Hi! i have CWM ext + rfs but i tryed flash ROM with Odin but don't work!
When i finish the flash ROM stock, i have connected my phone using ADB.
I have run:
"adb shell"
"cd system"
"ls -la"
but it's empty...
/data is empty ...
Why?

After you flash stock with Odin, "update" get's installed (the screen with opened paper box) and then it's stuck at bootlogo, you have to turn it off (quickest way: pull the battery off the phone) and turn it on in recovery mode (home + power button) and clean both data and cache to be sure. Then after reboot, stock will run.
If you want to switch back to ext-based ROM, install ext-only CWM (it will complain at startup about not being able to mount /cache), format all partitions (besides /sdcard and /sd-ext if you used it), mount /system and restore from backup.
It has to work.
Download CWM from phiexz - ext-only flashable from Odin.

I can't wipe data. I recive error:
E: format_volume: make_extf4fs failed on /dev/block/stl13
i have flash recovery ext only but i haven't solved

What have you exactly done that you messed it up so hard?
Tell me each thing you did. From the first, when you were still running stock.

I have flashed AOKP for Gio... it's OK... but after 30 minutes i have flashed a kernel...
i have run: wipe davlik and wipe cache partition...reboot and the phone goes in loop in the initial screen
I don't remember name of kernel... "delano-aokp-kernel"
Partition / data I think it is damaged
...

Quite strange to me what happenned. There are metods to repartition internal storage using GNU parted. I haven't ever tried it. I can't help you here. I only suspect something has tampered in partition table.

Hi!
I saw you on Android Themes section yesterday
First, you must install Custom ROM (that support the theme) before install that theme. Any stock ROM doesn't support much theming now.
So, your only choice is flash stock rom via odin, or install custom rom. :fingers-crossed:

I guess since he installed via recovery, the files goes or replaced in /system. So, if the that files on /system that cause bootloop, wipe data/factory reset can't solve this. Since it's only wipe /data (only my opinion)

didn't knew he was on stock
and a flashable zip can have directories to /data instead of /system/app if its only a theme.
and it wipes data, cache,sd ext, and android.secure.

[Q] TWRP Restored Successfully On /Data(f2fs) But Device Won't Boot.

Hi guys,
I am getting interested in these ROM flashing things recently, so I backed up /System /Data /Boot by TWRP after I installed all apps I want.
Just today, I tried to restore from one of my backups but couldn't get it work. CM12 just stuck on the boot animation screen forever.
The backup & restore processes were all perfect without any error, the MD5 also matched.
Here are some basic facts I made:
1. I wiped /System /Data /Cache /D-Cache before restoring.
2. I wiped /Cache /D-Cache after restoring.
3. Reflasing kernel -> NO change
4. Reflashing /System /GApps -> NO change
5. Fix Permission ->NO change
6. Wipe /Data = CAN boot
7. Restoring from another backup -> NO change
So clearly there is something wrong with /Data.
I'm thinking the f2fs /data just can' be restored by TWRP? but I couldn't find such information on the web.
Can anyone confirm this?
Thanks!

Without restoring data, it boots up properly?

Thanks for your reply.
I didn't try that, but I tried to wipe /data(not format) after restoring, and it booted fine.

I see that you changed your file system to f2fs.
Did you flash a modified TWRP to support the new file system after changing it?

I thought twrp2.8.6 supports f2fs because I could format f2fs and browse f2fs /data with its file manager.
Does it need further modifications?

I looked up on the internet and it seems that it does support f2fs.
What about the kernel, does your kernel support it?
I guess if you were using the same kernel earlier with f2fs then kernel should also not be the problem here.
Maybe it's just a faulty backup.
I don't know much about f2fs myself.
Maybe you should contact someone who does.

I'm sure this is not about kernel, because I tried restore /boot and reflash the kernel.
Besides the kernel that I use works fine with f2fs.
I also tried to restore another backup with no luck, maybe they both were faulty...

You mean 2 backups with faulty data partition?
That's highly unlikely to happen.
When you took those backups, did TWRP showed any error?

I read that the last CM nightlies got some sort of new compression implemented and that's why there's problems with restoring data. You'll have to wait for the TWRP creator to repair it

[Tutorial] how to format data & cache from ext4 to f2fs (cm12.1)

Maybe there is someone who do not know how to format the data and cache partition to f2fs (cm12.1 only), so I create this thread. Hope this tutorial can help.
The first step, copy the file mkfs.f2fs from /sbin to /external-sd (recommended). You can use file manager like root Explorer for example.
The second step, reboot the device into recovery mode(twrp recovery), copy back the files mkfs.f2fs from /external-sd into the /sbin
Step three, in the recovery mode, select wipe> advanced wipe> checklist cache> fs option > change fs> and click f2fs and Swipe for change. (if you don't see f2fs buttons, you must have a custom theme for twrp, or reload your themes to make f2fs button is visible. @vbvn thank's for your tips bro).
Repeat the same steps for the data partition.
And yeah,,, now you have data and cache partition in the f2fs formats...
Don't forget to backup Internal sd to safe your data (like a photos or mp3 for example).
For more detailed step, you can ask Google for it.
Greetings.
Sorry for my bad English

Screenshot

Thanks, that worked. I got the option for F2FS immediately after copying the file, though I have to copy it every time I have to format the partition else it says binary not found.

Good tip op. Also one can do a nandroid on data. Once cache and data has been converted you can restore data and reboot.

No it doesn't. And MUI will not read ext4 for you ext card either.

1. Yes, you can use this method to format /system.
2. As /system is read only, and F2FS doesn't really improve read speed, it won't be effective.
3. I haven't tested this, but I have seen no reports or have no reasons to believe miui supports F2FS.
There goes your answers. For next time, please read the thread, and use this little thing called Google. I've heard it's kinda awesome.

Any armani-dev based ROM should work just fine. Which is, almost every source based custom room out there.

Just the way you formatted to F2FS. Except this time, select EXT4.

Thnx for the guide @ippatt
Tip:-
no need to install additional theme. after copying file to sbin, just use "reload theme" option and F2FS option becomes visible...
OP may be updated with this tip.. thanks.

So I just have to do this for /cache and /data, and that will wipe data and cache, right ? Or will that wipe external / internal SD card as well?
I can just backup my data using titanium and do this procedure and just restore the data ?

Edit: just fixed, i had to pull out my baterry twice & now boot perfectly & FAST....)
Edit Again: seem to be if i flash exposed framework from twrp it ended up bootlop at reboot system, gues exposed hasn't fully support of f2fs or maybe there is something wrong with my phone, mcurrently my phone work fastly after flash CM12.1 R18+GAPPS+SuperSU 2.46

@ippatt
Nice tuts. F2FS menu comes out after I copied the mkfs using the TWRP Recovery's File Manager. The only problem is, why did I get the log "E:Unable to mount /cache" after formatting the /cache into F2FS? This happens with the /data too. "E:Unable to mount /data". What went wrong? :S
