E:cant mount /dev/block/mmcblk1p1 (or /dev/block/mmcblk1

been getting this error "E:cant mount /dev/block/mmcblk1p1 (or /dev/block/mmcblk1" with my g2 I cant flash from my sdcard or boot into os and when i restore a backup that I have using fast boot it just hangs when I try to boot up the system I do have clockwork recovery on the phone and adb access but cant mount the sd card please help thanks

A little punctuation please pal!? That was hard work to just read it.
OK, what are you trying to achieve? Is it just not booting under any condition?
... and you also cant restore a backup through "fastboot" or recovery?
Have you already tried a fresh flash of a ROM or is that a last resort to preserve data/apps?

Boot up into recovery > mounts and storage > Mount sd card > Flash a ROM or restore a backup.
I mean I'm just speculating, I've never had this problem before.
...and yeah wileykat's right, you can't restore from fastboot

Why couldn't you just use flashboot to flash the boot, system, and userdata partitions with your backup images? I thought flashing these types of partitions was the main purpose of the fastboot protocol to begin with. I hadn't heard that this doesn't work on the G2 (not sure why it wouldn't---is it something specific to the eng. hboot?).
And yeah, more details are probably needed to better understand the issue here.

I got it fixed. I had to bend the prongs on the sd card holder up to provide more contact. Thanks guys.

I am having the same error when I try to do a backup or rom upgrade. The strange part is that I can see the SD card in recovery mode......

nothing freezes on me, but EVERY single time (besides nandroid backup) I get that exact same message.
Does anyone have an actual answer? Like a workaround or something?
Or does it really matter as long as everything flashes
cheers

[Q] Can I access storage memory from CWM?

I have a Galaxy Nexus that won't boot. It goes through a boot loop. I've tried everything to try and get it working. I've wiped data/factory reset, I've formatted system and re-flashed ROMs that were already on my phone, I've tried restoring backups from several nandroid backups. It never gets past the initial Google splash screen with the unlock symbol.
I'm going to send it in for service, but I'm wondering if there's a way to try to access the flash memory to copy all the data to my computer? I've stupidly done tons of regular backups (Titanium, SMS, nandroid) to my flash memory on my phone, but never backed it up to my PC. I can see the directory structure through CWM 5.5.0.2, but I can't mount it as a USB storage device from CWM and I assume I actually have to be booted up to use ADB.
Any suggestions?

You should be able to do adb with the device in recovery mode. I'd recommend doing something like
Code:
> adb pull /data/media sdcard
This will copy the entire contents of the pretend SDcard on the phone (/data/media) onto a new folder on your computer called "sdcard".

I don't think there's a way to access the internal memory through CWM. For CWM to do that, is that to unmount that partition, and it cannot unmount data (where the sd-cad resides) as android wouldn't run without the /data partition, or so I've heard.
Feel free to correct me if I'm wrong.

Recovery is not Android, it will run fine without the /data partition mounted (though there isn't a whole lot it would be able to do then, since that's where all your flashable goodies would reside). CWM accesses internal storage all day long when you're flashing ROMs and kernels and whatnot.

Thanks! I assumed ADB wouldn't work in recovery because I tried it quickly on a PC that didn't have the drivers installed. I plugged in it on my upstairs PC and I'm doing a very lengthy adb pull as I type this. Thanks!

what exactly gets wiped when i wipe data?

Hello everyone,
after more then 2 years with my trusted N1 i finally had to move to a new phone because i broke the screen of my old one.
having the GN now for allmost a week, and within the first few hours of owning the device it got 3 OTA updates and is now at 4.1.1. i am quite happy with it but 2 days ago i startet messing around wiht it. so i ulocked the boodloader and rooted and got myself franco kernel on the GN.
as expected everything worked fine.
today i wantet to give some 3th party roms a try. i tried installing MIUI and euroskanks cm10. both with rom manager.
but on each of them i got in a bootloop after flashing, just showing the franco kernel boot animation.
i flashed both roms without wiping the data (just the cache)
i suspect that is my problem.
i am a little bit scared about the wipe data option for flashing new roms. on my N1 it worked fine since all my files on the sd card where not touched and i could get started allmost immediantly.
unlocking the bootloader of the GN wiped everything out off my phone and i had to copy it all back from a backup.
if i choose wipe data will that also (again) wipe my complete device or just the "OS part" and leave my data alone?
if it wipes everything how do i avoid having to make a backup of my data and restore it afterwards after each and every rom i flash?
i have noted the mnt/sdcard folder on my GN that (apparently) just links back to the root of the memory. what is the puropse of this folder? just to be compatible with "old" apps that insist on writing files to the SD-card or something else?
thanks for the info

no data from sdcard gets removed.
its basically a "NON REMOVABLE sdcard"... think of it that way.

1. It will wipe your "OS part" + apps. Will leave data in "sdcard" alone. Factory Wipe clears the virtual "sdcard"
2. Can't be avoided, I use Wugfresh's toolkit to make app backups a breeze. Takes a little more time than it used to when I had my OG Droid with a EXT partition but hey, at least you'll always have a current backup of your apps.
3. Yes. It'd actually be less obvious it's still called /sdcard/ if you weren't rooted and poking around . I believe JB switches this to sdcard0 now to account for devices that have external sdcards to be mounted as /sdcard1 and so on.

Ok, I guess I get it.
Just one more thing to make sure.
It looks like all my files are in the root of my phone and mnt/sdcard has just one folder but with the same files as the folder with the same name in my root.
When I wipe data now will it keep everything or just the files in my mnt/sdcard folder?

Custom recovery (AKA not CWM or TWRP or whatever you're using) will wipe your SD card. Just remember that.
All the custom recoveries wipe /data/ while keeping /data/media/ (your sd card).
Nothing on your "SDcard" will be lost.

I'm in the same situation as the original poster and would like a "definitive" answer. CWM has both a factory reset and a format /data option (in a separate submenu). Which preserve the content of the virtual sdcard ? Which is the raccomended way to try out a JB rom? I have 10+ Gb of data in the sdcard and i would like to avoid moving everything forth and back via MTP protocol...
Thanks

IF you are using CWM recovery, "wiping data" will erase the entire userdata partition EXCLUDING /sdcard. This means that everything under /data (except /data/media which = /sdcard) will be erased. This includes all apps you have installed in /data, and most data for those apps.
IF you are using a stock recovery, "wiping data" or "factory reset, will wipe the entire userdata partition, including /sdcard.
Wiping data or factory restore/reset/whatever does NOT touch the system partition or return the device to "factory condition". So if you have installed apps in /system or have root, the will still be there.

Touch 6.0.1.4 backup problem

Hi,
Trying to do a nandroid backup with touch 6.0.1.4 and it does not work. I try on sdcard and external sdcard and both fail.
Message I get:
No /sdcard/,android_secure found. Skipping backup of applications on external storage.
Backing up cache...
No sd-ext found. Skipping backup of sd-ext.
Backup complete.
Backup take like 15 seconds and the size is only like 20k so it is not backing up much.
I did reinstall touch a few time and fix permissions.
Any idea whats wrong?

I know this isn't a fix, as I don't use cwm atm, but I've had nothing but success using twrp(team win recovery project) perhaps give it a whirl, or wait for someone for familiar with cwm touch

I tried the same version of cwm as you. After a couple of days, my external sd unmounted and wouldn't remount. Since the recovery was the only thing i had changed in almost a month, i knew it had to be recovery. Flashed back to 5.8.4.5 touch, but had to take my external out, pull everything off, reformat, and put everything back on it. (Real pita considering i have a32gb card).

TWRP Restore Failed ATT GS3

Flashed the latest stable Carbon rom yesterday and decided it wasn't for me so this morning I rebooted to TWRP and tried to run restore. The restore failed and the only error i see in the console is
Code:
E: error opening '/data/lost+found'
I went ahead and did the standard wipe (which also gave the same error, though it did not say failed) and rebooted, assuming it would just throw me back into carbon, but it got stuck in sort of a slow boot loop. I finally got back into recovery and now I'm at a bit of a loss. I saw only 2 suggestions, one being wipe /data and the other to flash back to stock with Odin. I'm not against wiping /data if someone could could either confirm that it would work or tell me if it's possible to backup some stuff from /data to my external sdcard or pc.
any advice would be appreciated, thanks
also sorry if this is the wrong place to post, I didn't see where else it would fit, says I can't post in the GS3 troubleshooting area.
ATT Galaxy S3
TWRP v2.6.0.0

fixed
Ok, I'm up and running again. I ended up formatting /data through twrp after I found out i could copy files over to external sd through its file manager.
so in case someone else runs into this:
assumes you have a twrp backup on the external sd
1. move important files with twrp's file manager to sd card
2. format /data
3. reboot recovery
3. standard wipe
4. restore backup from external
5. reboot system and cross fingers
