[Q] Problem with loading Ubunto

Hello team,
i try to start the ubunto on my HD2 and after starting the haret application ubunto is loading and its hung on screen with the error
"mount: mounting /dev/block/mmcblk0p1 on /sdcard failed: invalid argument failed"
Failed to mount the SD card, Cannot continue.
/bin/sh: can`t access tty; job control turned off"
Could someone help me... Try to format the SD card but this doesen`t help.
The Host os is WM 6.5 1,66 stock rom. I`m thinking that my be the problem is comeing from bootloader because its stock . But if this may be cause the problem i will change the bootloader.

it failed to mount the filesystem because it could not find the folder "linux" on your sd card.
see the readme.txt.

i was facing a similar issue...i realized then that my memory card partition was typed as logical instead of primary...formatting my card as primary solved the problem for me....maybe u shud try it too...

[Q] mount external sd in recovery

hi,
i use Reflex rom from Civato (many thanks Civ:good.
Everything work fine in normal use (also the data/file in external microsd)
My first problem: when i install V8UNLOCKED multi ICS BOOTLOADER installed whit CWM
the process end fine but in recovery i see at the top: CWM Recovery v5.5.0.x(thor2002ro/digitex rev1.7.3)
And, after istallation when i back to Power menu i have:
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
The second problem, maybe connected whit the first:
Each time i try to install a rom update from external sd i have the following message :
E:Can´t mount /sdcard/
If I remove my SD, and insert it again, it mounts and i can update the rom.
I'v tried to wiping cache & dalvik partitions but both problems remain...
p.s.sorry for the mistakes in English and the noob questions..

? The MicroSD card that you can remove from the top should mount as /external_sd/
As for the messages about not able to open the log files could be...
1. The logs do not exist
2. The mount or location its referencing does not exist or is not mounted
3. They exist but you have no permissions to get to them
Sorry I cant be of much help in resolving... I am sure someone will pop on with a solution for you...

Right. The log files do non exist in sdcard. or in external_sd.
But. why I see. :CWM Recovery v5.5.0.x(thor2002ro/digitex rev1.7.3) at the top after I install the V8UNLOCKED ?
And what about the probmem whit read the external_sd in recovery mode:
E:Can´t mount /sdcard/
If I remove my microsd and insert it again, it mounts perfectly ?

A500 inexplicably bricked

Dear Experts,
Happy New Year
This is my first actual post on xda-developers but I rooted my beloved A500 with the advice on here just over a year ago.
The other night I plugged my device in to charge, all was well. When I woke in the morning the device was off, booting it would only take me to the first screen which shows the Skrilax_CZ ROM welcome screen. I tried booting it a few times, as you do, and each time I got the same result.
I was able to enter the boot recovery menu fine.
In green text I got the following:
E: can't mount cache/recovery/command
Under that it said:
E: Can't mount /sdcard/
E: Can't mount /cache/recovery/command
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log
I am able to get into APX mode, I only know this because the 'blackthund3r A500 Manager' is able to see the device when I try to manually put it into APX mode. I don't know if it helps at all...
I am now unable to get into the boot recovery mode since playing with the A500 Manager ion APX mode.
I found a similar thread:
http://forum.xda-developers.com/showthread.php?t=1953751
This suggests it is proper broken.
Does anyone have any advice on what I can try? If the device is dead then is there any way to retrieve my data which is not on the SD card?
Many thanks to you all,
Robbie

All i can suggest is you power down tablet , remove sdcard and put it in a card reader to save any data on it / format it / put it back in n see if u can do recovery ? or use different sdcard ?

Hi Brysie.
I have had the SD card removed while I tried working on it so that I wouldn't risk affecting my data on it. I seem to get the same results now whether I have the SD card inserted or not. Although I just had another try and it is now allowing me to enter the recovery mode again which it wasn't a couple of hours ago.
I am north east of the Shetland Islands on an oil rig just now and I didn't bring my card reader with me. I will try what you suggest when I get home which will hopefully be within a couple of weeks.
Hey RoverP4,
I was wondering if you manage to find a fix to this? I have had an extremely similar bricking. My message is a little different.
Code:
E:Can't mount /cache/recovery/command
Kernel: thor-kernel_v1.16mini
Updates on TegraOwners.com
Setting CPUO & CPU1 to 1GHz...
Done!
Fixing A500 Boot/Recovery Chechsums...
Running itsmagic
Done!
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/reovery/last_log
E:Can't open /cache/recovery/lazy_log
Thanks for any help.

You can try running babsector (search on the forum), that will attempt to repartition and format.
If that doesn't work then it is most likely due to hardware failure of the eMMC chip, so a motherboard replacement is the only real solution. Same thing happened to me, cannot install anything on it as nvflash cannot write to the device. Haven't gotten around to replacing the motherboard.
Install Skrillax_CZ's bootloader.
Install TWRP (I use version 2.4.0.0).
Wipe System and Cache partitions.
Install a compatible ROM. If you want something fairly vanilla, give Lightspeed a try.
Thanks for the suggestion. But Im almost sure the mother board was fried. It wouldn't let me mount the SD or flash drive. So I couldnt install anything. Replacing the MoB wasnt that hard. Heck I took it out 3-4 times.

please specify the exact partition layout achieved with minitool. we might be particularly interested in the presence/absence of other partitions (intended or unintended), their relative order to one another, and which ones are primary or logical partitions, etc.

[Q] Sd Card Partion

Hey Guys,
I am new this forum. I had Done my rooting and i installed a custom rom. I thought of increasing my Internal Memory by moving apps to sd. I rooted to CWM and partition my sd to 1 GB. And install Link to SD. Everything works fine. Guys i need a help is there any way to repartition to 512mb instead of 1 GB. So i could use more memory On my Sd.
Also
Do i need to uncheck everythning that i made during using link2sd in the process
Soloution
I know i may sound stupid for posting the solution since i am the one who asked for solution. I searched the whole internet to find the solution. Its easy to do that you don't need to partition etc etc. All you got to do is go to Settings -> Sd Card and Storage -> Unmount it -> And just format Boom You get your space back. I am writing this solution to people who have problem in removing the partition space
you can use cwm ro repartion your sd card or use computer to do it
cant mount sd
