[Q] A100 bricked after short fall? Help please

I had been running the leaked ICS for a couple of weeks, when after a short fall (1 ft) my Iconia A100 failed to boot. After a power - volume up keypress, I eventually get the following errors:
E:Can't open /dev/block/mmcblk0p5
(No such file or directory)
E:failed to mount /cache (no such file or directory)
E:Can't mount /cache/recovery/command
E:failed to mount /cache (no such file or directory)
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:failed to mount /cache (no such file or directory)
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
E:failed to mount /cache (no such file or directory)
E:Can't mount /cache/recovery/last_install
E:Can't open /cache/recovery/last_install
E:Can't open /dev/block/mmcblk0p5
(No such file or directory)
E:failed to mount /cache (no such file or directory)
Then the Android system recovery utility appears. I can navigate up/down using the volume rocker, but nothing selects any of the options (reboot_system_now, apply_update_from_external_storage etc.
USB drivers do not recognize device, and when I try to boot normally (power button) it gets stuck on the first ACER logo.
Any help or advice would be greatly appreciated.
Thanks in advance.

You could try resetting it with the small hole at the base. You could also try placing the ICS update.zip on your external sd card, then booting into recovery.

I have tried both the pinhole reset - just turns off unit. Also tried ics leak as update.zip on sdcard but I can't get the unit to update. I can get to the recovery screen and toggle between the options but I can it to select anything. I've also tries the power - volume down then orientation lock switch. That process flashes text in screen (erasing cache?) But no change.
Thanks

Make sure the file has the correct name. Just name it update since it is already a zip file to avoid the "double zip" file extension.

If you are seeing text on the screen about erasing cache, you are in the right spot. I've had my tablet sit by seemingly doing nothing for 5+ minutes after starting a hard reset and then it pops up with the configuration screen. Try again the hard reset. You are on the right track.

The text goes away quickly, reboot and then stuck on Acer screen.
How should the selection for recovery screen be? I can toggle between menu items but not select one.

Press power button to select an option

That is what I thought and have done in the past. The power button does nothing during selection but eventually power the unit off (and on again etc). Thanks

Try 'slapping' the device few times.
My A100 hardware buttons (power, volume, rotation) and front camera doesn't work after a short ball, and slapping the device back (precisely, on the back, beside the camera, near the volume button) few times gets those function back, the front camera now works again.

Thanks for the tip. Will give it try.

If you have managed to get the CPU ID, you can restore from EUU (APX mode). But if you don't have your CPU ID, I think you can't do much, just like me.
I sent my A100 to ACSC (Acer Customer Service Center) after trying to restore from EUU, but the EUU begs for the CPU ID, which I don't know.

Stuck at Google Screen

Hi I'm stuck at Google Screen and not sure what the problem is.
I had the below responses in Clockwork Mod when in that recovery and then switched to TWRP, still to no avail. I read that it may be the partitions, but not sure how to correct. I can connect to the phone and ADB to the bootloader and can flash recoveries, but doesn't seem like I have an SD card anymore. Any/all help would be extremely appreciated. I'm not new to android, but this experience is proving to me that I have no clue what I've been doing.

I'm on MAC and it seems like toolkit is windows based? I'm pretty sure I wiped out whatever ROM is on the phone. I tried pushing zip folder to the phone and just got "Permission Denied". I know I'm missing something, because I can ADB to reboot, I can flash recoveries, I just cannot access the SD card or get passed the Google splash screen
Code:
~/Desktop/androidsdk/platform-tools/adb push ~/Desktop/androidsdk/platform-tools/image-yakju-jwr66y.zip data/media/0
failed to copy '/Users/SeeBusiness/Desktop/androidsdk/platform-tools/image-yakju-jwr66y.zip' to 'data/media/0': Permission denied

Should be /data/media/0. You don't have the / before data

[Q] E: Can't mount /cache/recovery/command ?

Hey guyyyss, I'm begging for help. I'm currently using CM11 TeamCanjica Build11 on my device. It worked fine for 2 weeks, but suddenly yesterday when I want to turn it on, it wont start, its stucked at CM11 Logo, I tried to go on Recovery Mode (CWM), but it said like this :
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've tried re-flashing the STOCKROM (after wipe data, wipe cache, wipe dalvik), the ODIN process is successed, but still it can start, i even tried to flash STOCKROM MB4 (with PIT and CSC files too), and even tried to flash it BACK to GB, but it still stuck on CM11 logo (how could it be still CM11 logo since i've flash it many times with stockrom, i thought it should be samsung logo.)
Does anyone know how I can fix this? Even Samsung Service Centre said that they cant fix this up, heeeelp :'(

TWRP failing to mount /data + bootloop

Hi all,
After spending all my morning looking at various solutions I've resulted in opening a new thread.
I was trying to install a stock rom this morning however was stuck in a bootloop on the LG logo.
Trying to go back into recovery resulted in a black screen after the TWRP logo.
I was attempting to re-install TWRP to see if that would fix the problem however I only managed to get into Download Mode (is this the same screen as the Bootloader?) and adb/fastboot couldn't find the device.
Magically, TWRP boots up now however in the log it states the following:
Code:
E: Could not mount /data and unable to find crypto footer.
E: Unable to mount /data
E: Unable to recreate /data/media folder
E: Unable to mount storage
E: Unable to mount /data/media during GUI startup
E: Unable to mount /data/media/TWRP/.twrps when trying to read settings file
If anyone can point me in the right direction in how to resolve this I would be grateful.
Regards,
Ash

Looks like you trying to install stock Rom, Given the account you used a flashable zip. It didnt install all the way. and now your stuck with a messed up unstable device......
If you can get into TWRP, wipe everything at least 2 times.. Then install a Flashable ROM/gapps ect..
If you cant get into TWRP and only into Download mode.. Then you will have to flash stock kdz file...............
you can find all types of guides on that around here............

Thanks for your response, once I got into TWRP I couldn't wipe anything as it couldn't mount any partition nor could I flash anything from the external sd.
When I plugged it in there was no internal memory so I decided to use the TOT restore method to go back to stock which was successful and now I've got my custom stock rom back on.

Samsung galaxy s4 MINI GT-I9195 stuck on logo screen

Hi,
I installed clockworkmod recovery 6.0.5.1 via Odin, rooted my Samsung Galaxy s4 Mini and installed cyanogenmod 11 (from this thread http://forum.xda-developers.com/showthread.php?t=2558685). Everything went fine, but when I enabled wifi connection my device freezed and when I removed the battery it wouldn't power on again: the display didn't light up and it wouldn't even vibrate.
After a full night charge, the device turned on again, but it is stuck on the black screen with the white Samsung logo and a yellow writing saying "Set Warranty Bit: kernel".
I tried flashing the stock rom but it didn't work (https://samsung-firmware.org/download/Galaxy-S4-Mini-LTE/62n1/ITV/I9195XXUCOG1/I9195ITVCOG1/). I then tried installing another cyanogenmod, but the result didn't change, so I flashed different recoveries through Odin, but I can't get them work: I am stuck with the cwm 6.0.5.1 and can't change nor the recovery, nor the ROM.
In the download mode I can see "write protection: enable" on the top of the screen and if I enter in the cwm recovery I get on the bottom:
Code:
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
E: Can't mount /cache/recovery/last_install
E: Can't open /cache/recovery/last_install
Do you have any ideas on how could I get it to work?
Thank you.

Yes I can, but the problem is that when I try to flash a ROM to boot android the recovery says that the installation is complete, but when I reboot nothing changed. Is there an effective way to replace this recovery and install a ROM? Thank you for your time.

Well nooby stuff - did you Clear dalvik cache and cache partition? and do the system and data wipe before flashing the rom?
