Can't see contents of /sdcard from Amon Ra recovery

Going into the console from recovery, the sdcard folder exists, but is empty. I thought at first it wasn't mounting, but I am able to using the nandroid backup and recovery tool. I was using the console earlier to rename my nandroid backups so that I can differentiate them. After booting into the latest CM6 nightly, this happened.
Also after exiting console by typing 'recovery' and entering it again, I get stuck and am unable to type anything or get out without a hard reboot.
I appreciate the help.

try /mnt/sdcard

I don't seem to have an /mnt/ folder anymore.
I can see things on my sdcard when I go to flash zip or nandroid recovery. But not from console...
I tried to "mount -t vfat /dev/block/mmcblk0 /sdcard" but it says invalid argument.
Output of cat /proc/mounts is:
rootfs / rootfs rw 0 0
tmpfs /dev tmpfs rw,mode=755 0 0
devpts /dev/pts devpts rw,mode=600 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
/dev/block/mtdblock4 /cache yaffs2 rw,nodev,noatime,nodiratime 0 0
/dev/block
EDIT: I got it working, thanks. I flashed Clockwork recovery and then flashed Amon Ra over that. That was strange.

"locked" internal SD (MMCBL0)

First of all, I'm experienced with android hacking/rooting/whatever but not so much with the galaxy tab.
So, I have this weird problem, whatever changes I make to a partition on the internal SD (including /data and /sdcard) doesnt actually gets applied to the internal SD. This include changes made by installing a app, using a file browser, using mass-storage, a shell command as root, reformat in recovery or even when using ODIN and just re-partitioning the whole thing.
Is this a known issue or does anyone have suggestions?

Tried flashing CF-root and formatting from CWM. /data and /sdcard still have all their data after being formatted.
edit:
Tried fsck, umount, and more linux tools. nothings helps.

Im trying to get to the bottom of what sounds like exactly the same issue.
A few more details noted here:
*edit to note I cant post external links*
My current guess is that at some point it's locked "read only". I'd just be happy with a working 2.3 tab at the moment. Forget any other roms lol.
If you get any further with it, I'd appreciate any answers you come up with. Visa versa if I beat you to it.

This exactly is my problem. Has someone here know the problem?

Thats three of us then. I'v found another two instances of the isue on "the Galaxy tab fourm" and posted a long log of trying to resolve it.
Those were both some time ago however and havent resurfaced. There is another thread on XDA comlaining of the same issue but no solutions or fix.
I', still trying to get this sorted so if I do encounter a resolution beyond "pay someone to fix it" then I will let you know.
Unfortunately I cant even do that as without knowing the cause I doubt I'd get it back repaired....
Any assitance would be very welcome, Im using just the browser on a p1000 as nothing else works.... Depressing lol.

I have exactly the same issues with a SGT-P1000 GSM. Tried everything but after reboot all data, that i wiped is back on internal memory. i could wipe partition and create ext4 partition with mini tool partition wizard, but just a couple of moments later after creating the partition successfully the partition changes back to fat32 and all data is back on internal memory, neverending story ...

Further research and a new error message suggests that there might be a link to the "system UIDs Inconsistent" error which has been reported across the forums for a variety of devices.
Im looking into it...

Hello! I have the exactly same issue. Has anyone been able to solve this?
I've tried cyanogen rom, the official (stock) ROM and that does not seem to solve my problem.
I've also tried, with a custom kernel, access the ADB shell as root on recovery mode and anything that I do, doesn't "stick". FDisk, file creation, file removal. NOTHING.
I'm a week like this and this post is the only reference I've found that has the exactly same problem that I do.
Please, do tell your findings.
Thanks,

Little dont understand this, but i try to help
Maybe you can try dd command, i never using this for my tab but i often using in my linux..
dd if=/dev/zero of=/dev/path/your/sdcard
dd is unix or linux tools for low level format and can be used to make image file too. Please backup your data first, i dont responsible for your lose..

[HOWTO] Dual-Boot P31xx

Dual-booting has always intrigued me. I dual-boot between Windows and Linux on one of my computers, dual-boot between stock firmware and RockBox on my Sansa Fuze v2, and I decided to find out how to dual-boot my Galaxy Tab 2 7.0". It took a couple days of work, but I have found one way to do so using the external SD card.
In the future, if I can work it out, I will provide a method for dual-booting using only internal storage. Update: I have successfully tested an internal dualboot setup. I will post details later.
Warning: While I am not aware of any specific way this could brick your device, stuff happens, so don't blame me. I've tested this and found no problems, but you may not be the same.
To use this method, you need a microSD card at least 8GB in size. If you use 8GB, though, you will have pretty limited space for storage, so a card 16GB or greater is advised.
Preparing SD Card
Repartition your microSD card using whatever program suits you. You need to shrink the first storage partition to make room for the new system partitions. The new partitions should take at least 5GB, so be sure to leave at least 5.25GB. You can always resize later if you need to.
After shrinking your storage partition, create four ext4 partitions in this order: system (min 800MB, recommended 1.25GB), cache (min 500MB, recommended 700MB), data (min 3GB, recommended 5GB), and EFS (min 21MB, recommended 32MB).
Verify your partitions on your tablet by inserting the SD card, booting into CWM, and running "parted /dev/mmcblk1" (no quotes) over ADB shell.
Flashing External ROM
Now you just need a ROM to flash. Most ROMs are not packaged to run from external SD card. You MUST either use a provided ROM or edit one yourself. I provide here a repackaged version of the 8/28 CM10 nightly which can flash to and run from your SD card. If you want to edit a ROM yourself, see the bottom of this post.
Boot into CWM and backup. You will need your backed up boot image if anything goes wrong.
Now flash your ROM. It will install to the external SD card on the appropriate partitions if you did everything right. Reboot: you should be in your new ROM.
You'll probably want a Google Apps package. See below for packages for external dualboot.
Using Your Dual-Boot Setup
Your internal and external ROMs do not share internal storage, due to the odd nature of the SD card fuse tool.Your external ROM has an "internal SD card" of its own. You may find a way to mount the internal /data/media to the external ROM's /sdcard. My new ROM conversion script will add attempt to mount the internal ROM's storage to /storage/intSdCard
The ROMs I provide here include a script in /system/bin called "bootinternal." Run this from a terminal emulator or adb to switch from the external ROM back to the internal one. I have attached a script called "bootexternal" to this post. Use it on your internal ROM to switch to the external one (remember to set the executable permission).
In order for the boot switching scripts to work, you must do some preparation. On your external ROM, place the internal ROM's boot.img in /sdcard/Boot/internal.img. For your internal ROM, place your external ROM's boot.img in /sdcard/Boot/external.img.
If you ever need/watch to switch ROMs manually, run the following commands in a terminal emulator or over ADB, replacing "boot.img" with the boot image of the ROM you are switching to:
Code:
cat boot.img > /dev/block/mmcblk0p5
reboot
Alternatively, you could switch boot images using Mobile Odin.
Update: I would skip using my prepackaged ROMs now, because I have uploaded a converter script that will actually do a better job. These will configure the "bootinternal" and "bootexternal" scripts automatically.
If you ever need to wipe your data, cache, or dalvik cache, see the next post for CWM zips.
Downloads
Roms for External SD Card:
CyanogenMod 10 Nightly (8/28/2012)
AOKP P3113 Stable
Note that these are probably unnecessary now, because I provide a script to convert ROMs automatically on Linux.
Google Apps Packages for External SD Card:
Gapps for Jelly Bean - Use for CM10, AOKP, etc
Gapps for Ice Cream Sandwich - Use for stock, RomsWell, etc
If I ever have time, I plan to upload SD card images which you can use to partition your external SD card automatically.
---
Repacking a ROM for Dual-boot from SD Card
Note: You no longer need to do this manually. I have uploaded a script which automates the conversion process. See the next post for download.
First, you need to extract and unpack the boot image. There are tools and scripts available for this, so find one.
Once the boot image is unpacked, you need to edit init.espresso.rc on the ramdisk. Find where the partitions are mounted and change the code to look like this (yours may look slightly different depending on the ROM, but just be sure to replace the default partition mounts with those of your SD card partitions):
Code:
#mount ext4 /dev/block/platform/omap/omap_hsmmc.1/by-name/FACTORYFS /system wait rw
mount ext4 /dev/block/mmcblk1p2 /system wait rw
#mount ext4 /dev/block/platform/omap/omap_hsmmc.1/by-name/FACTORYFS /system ro remount
mount ext4 /dev/block/mmcblk1p2 /system ro remount
#mount ext4 /dev/block/platform/omap/omap_hsmmc.1/by-name/DATAFS /data wait noatime nosuid nodev crypt discard,noauto_da_alloc
mount ext4 /dev/block/platform/omap/omap_hsmmc.1/by-name/DATAFS /data2 wait noatime nosuid nodev crypt discard,noauto_da_alloc
mount ext4 /dev/block/mmcblk1p4 /data wait noatime nosuid nodev crypt discard,noauto_da_alloc
#mount ext4 /dev/block/platform/omap/omap_hsmmc.1/by-name/CACHE /cache wait noatime nosuid nodev nomblk_io_submit,errors=panic
mount ext4 /dev/block/mmcblk1p3 /cache wait noatime nosuid nodev nomblk_io_submit,errors=panic
#mount ext4 /dev/block/platform/omap/omap_hsmmc.1/by-name/EFS /efs wait rw
mount ext4 /dev/block/mmcblk1p5 /efs wait rw
Repack the boot image and stick it back into the ROM. Then edit the updater-script, and change all references to the internal system partition (/dev/block/mmcblk0p9) to the external system partition (e.g. /dev/block/mmcblk1p2). If any other partitions are referenced, change them as well.
Optional: insert the "bootinternal" script in /system/bin and the a script to mount the internal storage in /system/etc/init.d.
Your ROM is ready to go. Flash and be happy!
Thanks to Johnsel for helping me edit the boot image and pointing me to sendust7's work on the Atrix, who I also thank for his precedent.

CWM Zips for Wiping External Partitions
If you ever need to wipe /data, /cache, or dalvik on your external dual-boot partitions, you can use these CWM zips to do so.
Update: Here is a script to automate the conversion of a ROM from standard to external dualboot.

interesting... gonna try this later...

Nice guide! Dual boot with stock and cm9/10/AOKP would be ideal.

Confirmed?

Absolutely. If you're running stock, just follow the instructions to partition your SD card, then flash the provided AOKP package and (I assume you would) the gapps package. You should boot right into to your external AOKP installation. Then just copy your stock boot image to /sdcard/Boot/internal.img and run "bootinternal" from a Terminal Emulator or adb shell to return to stock.

BRILLIANT !!!
A few suggestions:
Possible to have a GUI to switch ROM or even better to have it at boot (through kernel).
Script to Automate the process of converting any(P31xx) ROM to dual-boot. It will take away pressure off you.
Thanks !

thanks for the tutorial.

The GUI may or may not happen, since I, while familiar with partitions and scripting, don't know much about Java or Android development. I'll look into it, though. Having it run at boot through the kernel is beyond my skills. The closest I could do would be an init.d script.
As for a script to automate the conversion process, that seems doable. It only involves two files (init.espresso.rc in the boot image and the updater-script), so I could see that happening. I'll try to do something with that.

This is very interesting!
But I think it is better if we can install dual-boot like CM10 and some porting of Linux desktop version, chrome OS (love it) and other
I follow this thread!

Update: I've added a script that automatically converts ROMs to external dualboot format. I advise using this script instead of my provided ROMs. Just open a terminal in the script's directory and run:
Code:
./convert.sh rom-to-convert.zip
It will automatically edit the boot image and updater script, as well as configure the dualboot scripts. Go back to the second post to download.

Dual-boot question
Sorry for offtop, but your work is very interesting for me. I have GT-P6800 (Tab 7.7) and will try your method on my device. What can i do for it? May be change numeration of partitions inside a script? And firmware counter will be ticked or not? And my current firmware in internal memory will be untoched? Thanks for your work again!

I would assume our tablets are very similar, so my method probably would work as is. To be sure, extract the updater-script from your rom and send it to me, along with the boot image, and I'll check it out. Your firmware counter will not be increased, and your current firmware should not be affected.

marry me. I just asked the dual boot question like a week ago lol

Hi, this is my p680 kernel & updater-script:
http://hotfile.com/dl/170647189/80fec16/P6800.ZIP.html
Please, check it!
Also, i have some questions:
as you know, only 4 primary partition allowing on sdcard. I create 1 partition primary fat32 and 4 partitions logical ext4. Is this ok?
And how can i check partitions directly on tab? Terminal emulator not understand parted command, and from recovery TWRP 2.2.0.0 terminal asking me about from which directory execute commands. I try few directories, but parted/dev/mmcblk1 command show nothing to me.
Thank you for your adwise.

I'm having problems unpacking your boot image. Run the command "mount" on your tab and give me the output. I looked in your updater-script, though, and that seems compatible.

I was able to put 5 primary partitions on my SD card. Are you using an MBR partition table or GUID partition table? You need to use GUID to have 5 primary partitions. Anyway, I don't know if it will make a difference for logical partitions. Once you can check the partitions from your tab, I'll be able to tell you if it will work.

When I first ran across it, I wasn't sure what it was, so I added it for safety.
And what makes it need such a big cache partition?
Click to expand...
Click to collapse
I'm not sure. I decided to keep it close to the original cache partition size, which was 700+ MB. However, I've found in another setup that I can get by with half that. In my internal dual-boot setup, I have a 384MB cache partition.

[Q] erased cache, need help with ....

Well as the title says, while installing twrp I erased cache. Now recovery loops, so how do I rebuild my cache? Does anyone know? I'm rooted, S-off, running stock KK up to date.

Re flash the stock kitkat update. Clearing your cache shouldn't have broke recovery or the rom. You either wiped something you shouldn't have and didn't tell us or somethings broken with your copy of TWRP

Some folks execute a "fastboot erase cache" after flashing a recovery. Do not do that! Instead, either "fastboot format cache" or leave it alone. The fastboot erase cache command just blows the file system away and leaves you with an unmountable /cache partition until it's formatted (wipe will do that if you end up with errors about 'cannot mount /cache').

rebuild your cache partition? or your cache filesystem? two totally different things.
if your disk is wrecked (partitions no longer valid) you're likely into RUU.
If your disk is fine (partitions are there, just no file system), TWRP should boot fine, it'll just piss and moan about /cache not being there. If it keeps restarting to the curtain (the TWRP graphic while booting) no big deal -- adb should still be up. If it does come up, you can 'wipe cache' and it'll rebuild the file system for you. Either that or use fastboot to format it.
Either way -- if you actually placed interesting stuff on /cache (why would you do that?), it's gone. The cache partition is 99% useless to users, so it would surprise me if you put stuff there.
Here's what I'd do:
1) Boot TWRP (get my 2.7.1.1 version, fastboot flash it, start it up);
2) plug the phone into usb:
3) adb shell
4) mount
copy/paste what that last command says and let's see what's really up. If TWRP won't boot, you have bigger problems than you lead us to believe.

Ok, more info: phone works. no recovery it just keeps showing the curtain over and over...... So now ADB....can't do a thing with it. Can't fastboot flash anything.....error: cannot load 'openrecovery-m7wls-2.7.1.1-06-05-2014' so what now?

I have no idea why you think /cache is your problem:
"/dev/block/mmcblk0p38 /cache ext4 rw,seclabel,nosuid,nodev,noatime,data=ordered 0 0"
It mounted fine.
As for flashing TWRP, you have to give fastboot an actual file:
"error: cannot load 'openrecovery-m7wls-2.7.1.1-06-05-2014"
The file is (assuming you didn't rename it) "openrecovery-m7wls-2.7.1.1-06-05-2014.img" -- there's an extension on the end.
If you did rename it, then you didn't place the file where you have fastboot. Either give the *full path* to the .img file, or move (or copy) it to the directory in which fastboot exists.

Thanks for taking the time to help! This gave me a reason to update my tool box for android. It's funny I never had to use a file ext. before when installing. It was that simple! So twrp is up and running again, I wonder why it was looping.....for another time perhaps. Thanks once again tdhite!!!

Internal Memory not accesible after Custom ROM CM12 Installation on Xperia TX

Hi ,
I have a specific problem , i tried installing custom ROM CM12 with custom kernal in my existing android 4.3 . I was able to successfully upgaraded to 5.0 from 4.3 but in turn i belive something went wrong and now my internal memory is not accessible .
Though i am able to down load apps and have dedicated 1.7GB for that , plus have an internal memory of 10 GB , still i cant save picture and neither i am able to access my phone internal memory via PC and cable . Though i have rooted my phone already (Super SU) and when i connect my phone in recovery mode , i am able to access my internal memory .
Please suggest some recovery , as i cant even use Camera and Gallery .
Also my phone doesnt detects external SD as well .
Please send solution at [email protected]
Thanks

Good Luck!

You'll have to format your internal storage from phone's storage settings. You will lose all data on your internal storage, so make sure you back-up before doing this.

1.- It doesn't even seem like that user has an account on XDA anymore, so no point in responding.
2.- In case anyone else reads this... that will work, but you don't have to format your internal memory. Use the search function.

hi finac , i dont have any specific option for phone storage in OS5.0 lollipop. Its only shows SD storage erase , which i believe is not format .
I have also tried reset factory data and erase Sd card , still the same rather nothing happened after that rather phone booted normally with all information intact , with information i mean my apps logged in with personal details .
Any other option ?
Does it has to do something with void.stab ??

Dear Antiga,
1) dont know to whom you are referring to for active account
2) Use search function to search what ? just to re-iterate , i am unable to access my internal memory and due to this all apps related to internal memory like camera, whats app , share function are not working .
Tried flashing ROM many times , still the same

this is also in addition , that i can now see 2 separate internal memory , previously which was showing as one
