[Q] eMMC fail? - Nook Color Q&A, Help & Troubleshooting

Is there anyway to check if the eMMC fails?
I was using ICS for several days, and I powered on the Nook after it was out of power one nite. Suddenly, it stops at the Cyanogen "loading..."
I'ved tried to boot into Recovery, and it stops at the Cyanogen "loading into recovery" ..
After several tests and trying, I finally use bootable uSD to boot into CWR 3.0.2.8, and now it shows can't mount boot/system/data if I try to format these partitions.
I am wondering if the eMMC is broken, and how can I fix it.
Appreciated and sorry for my bad English.

Help~~ I can boot into CWM on uSD card, but can't mount /sdcard

I don't know what happens I was stuck like you then loaded that post onto a 4gb SD and hoped to boot into a Tom but recovery posted up then all I did was push reset and bam miui booted [previous ] rom and configuration I don't know if what I did really helped but all I know was it was bootlooping at cyanogenmods logo with booting symbol. Since its my wife's tab I just through 1.4.1 nook rom so she's happy now.
Did you try what I did to see if it would help out at all and do anyone know what is going on with this flashing was never this weird 6months ago when it was mine running honeycomb..

Yes, I did try the method you mention. The only thing I got was a blank screen.
I tried the "fdisk" method, and found that there is no block device, so I think the hardware (eMMC) was broken. Just need to confirm that.
Thx anyway.

I think I bricked my myTouch 4G installing Virtuous Unity?

Help anyone!
I rooted my MT4G, download and installed Rom Manager, loaded Rom Manager into the memory, download Virtuous Unity Rom. I rebooted into CWR, I wiped the data, wiped the cache, wiped the Dalvik cache and then installed Virtuous Unity.
The install went well, the phone booted into the rom (at least into the start up screen where you pull the link) then a black HTC screen stayed on for about 15 minutes (I didn't want to damage anything so I waited) I pulled the battery from the phone and it wouldn't boot anymore.
I held the down key to boot into the HTC recovery screen I still saw the S-Off so I selected recovery and it rebooted the phone into the CWR but it won't show my anything but the lil guy in the hat No Text or Nothing. I knew at this point I was screwed.
I tried to load the stock recovery PD151MG.zip file but it wouldn't load.
Please tell me there is a way out of this? I did some research and I saw something about an ext partition . Can I get CWR to work again or am I screwed??

EDIT: i didn't fully read your post, sorry.
You can use adb to flash CWM image again
I didn't do a Nandroid.
When I hold the down button and launch into the HTC recovery screen (where I see the S-Off) I click down to Recovery and press the trackpad (nothing happens) it says " Power" to select item. I press power while recovery is highlighted and then it rebooted to the Hat with a green half circle with a arrow point back to the hat.
Below the hat it says: ClockworkMod Recovery v.3.0.2.4.

what happens when you are on the screen with the hat when you press the back button on your phone?
do you have the engineering bootloader? do you have abd setup?
I know how to use ADB but I don't know how to flash CWM. Can you lead me to the link? Please man!!!
Can I use ADB even though my phone won't boot into a Rom??

Just making sure, but you put it on your sdcard and then went to hboot and it didn't recognize it? Usually that works flawlessly...

you have to select "bootloader" on the white screen then it will try to detect it

Stuck at CM7 green logo "loading" screen, cant boot to recovery

Hey guys, I have not used my nook in like 6 months now, and I decided to pull it out yesterday only to remember what had happened to it. When i try to boot it, it gets stuck at the green CM7 logo that says loading... under it. When I try to boot to recovery, it is the same screen, but it just says "booting into recovery...." I tried formatting the SD card and flashing clockwork again, no luck. I even tried a different SD card. All I got to was "loading..." If I remember correctly, when It first broke 6 months ago, I think I was trying to go back to CM7 from CM9, but I cant remember clearly. Hopefully someone knows what to do, thanks!

You are in a recovery bootloop with no recovery. Go to my tips thread linked in my signature and look at items A8 and A10. I have a specially modified CWM SD that will get you out of that.

Fixed bootloop, back in bootloop. Crap.

How it started: I use a NC with mirage 7.2 flashed to the emmc in my car. It runs Torque to display engine data, and is switched in and out of sleep with the ignition. Two days ago I started the car and got the low-battery "exclamation point" icon thing, so I figured the charging cable must have come loose*. I took it all out and left it charging overnight, but when I went to boot it in the morning it was stuck in a cyanoboot loop. I couldn't power the device down or enter emmc recovery. When I completely unplug the NC I can't do anything, the screen remains black no matter what I press, except it flashes white every 5 seconds or so. If I manage to plug it on, get to the cyanoboot loading screen and unplug it while holding the power button down at the right time, I can sometimes get it to power off completely.
What I have done so far: Tried various recovery SD methods, none of which worked. Wiped cache/data/system, factory reset, tried loading 7.2 again over the top of whatever is left in there, lol. Basically after it first happened I probably made a big mess of the file system in a desperate attempt for some kind of stability. I tried this recovery SD: http://forum.xda-developers.com/showthread.php?p=25354258#post25354258 ; section A10, and managed to get into CWR. I've never felt such joy in my life.
What finally worked: I repaired the 2nd partition with the help of this thread: http://forum.xda-developers.com/showthread.php?t=1759558 . I did not repair or format any other partitions though. After repairing the partition, I did a factory reset and flashed mirage 7.2 and gapps back onto the emmc. Before I rebooted, I swapped a clean SD in but it still went back into the bootloop..BUT...when I put my recovery SD back in it booted into 7.2! I set everything up and was happy to have it running again. Battery level was at 88%.
What made it stop working: I was testing to make sure the NC would enter sleep mode when disconnected from power, so I unplugged it. Everything went black, no "sleeping" screen, just a hard shut-down. I powered it back on and I'm now back in a cyanomod boot loop.
So...any ideas? If there's a way to completely wipe and reinstall everything I'm OK with that. I've never used ADB before but I'll give it a shot if someone can lead me in the right direction. Thanks in advance.
*I'm using a 2amp USB car charger with a modified data-looped cable for a/c style charging in the car. I know the supplied nook cables are prone to going bad, and this may have happened with the vibration of the car and all. Not sure.
Little update: I can sometimes get into TWRP by selecting the "normal emmc" boot from the cyanoboot screen. I don't understand how that's possible, as I flashed that on my original install of 7.2 months ago. Guess I need to figure out how to completely wipe and re-flash everything.

To completely wipe and reflash everything, do the other two zips that you said you did not do from my partition repair thread.

No luck with that. Here's exactly what I did, so tell me where I might be going wrong:
1) Burned an image of the 6.1.0.2 recovery onto SD, then put the (2) recovery zips and the (1) format zip as well as the mirage 7.2 and gapp zips onto the SD.
2) Booted into cyanoboot, it took a few tries to get out of the loop and into CWM. Note that I can't power on at all unless it's plugged in. As soon as I unplug the NC it turns of except the screen will flash every 5 seconds or so. Once I got into CWM, I installed both partition repair zips, starting with the 1-4-5-6-7-8, followed by the 2. Rebooted. There were no errors at all.
3) Again it took a few tries to get out of the bootloop and into CWM. Installed the format zip and rebooted again.
4) Installed Mirage 7.2 and gapps and restarted, but went straight back into bootloop. I know that the rom requires a clean formated SD card, so before rebooting after I installed the zips I took out the SD card, formatted with SDFormatter and reinserted in into the NC.
I'm beginning to think this is something hardware related. :crying:
Sounds like there might be some bad data in emmc, I had this problem before and fixed it by formatting everything , even emmc and wiping dalvik cache. Then boot off a SD card using the latest cwm.

It is possible that your partition table is messed up. The only way to find out is to boot to recovery, connect your USB cable to the PC and run ADB. It is also possible to make a CM bootable SD and use terminal emulator to check it out.
Once you get ADB shell or terminal emulator working, type the following command:
fdisk -l /dev/block/mmcblk0
It should say 965 cylinders, 4 heads, 63 sectors.
If it does not, we need to do a manual repair.
You can also abandon emmc and just run off SD.

nook color dead after updating cm10.1

guys my nook color was running as smooth as a butter.i brought it one year back.i initially started out by running cm7.2.then i got clockworkmod recovery.and i updated to cm10 nighties and later cm10.1.i used to update nighties of cm10.1 daily by using cyandelta.however i installed rom manager and it showed me a new recovery so i downloaded and installed it.after that the cyandelta used to download update but those had to be manually flashed by rom manager.
About two weeks back i downloaded nighties through cyandelta and flashed it through clockwork mod recovery.ever since that time its refusing to power on.when i put it for charging ,the orange light of the pin lights up and on full charging it became green .i tried to open nook to remove battery but found there are three battery connectors covered with some rubber material .i disconnected and then reconnected .but it is refusing to show any sign of life.on connecting to laptop and trying to switch it on it momentarily tries searching drivers.i have read all posts.made bootable sd card used all leapenlars files but of no respite.Infact once while trying to write image to my sd card i wrote the image on my ext hard drive and lost all my data.finally i gave up and have ordered nexus 7.i am a doctor nephrologist i need tablet for reading articles and book . if any one can help me out i willl be pleased . i have been trying since last two weeks as i always believed nook was indestructible .please help me
Do you know anyone else with one of these Nooks? I've heard of the charging cables going bad and causing all sorts of freak-outs, and you can't just use another android cable to do it. I know if your Nook is completely dead, you won't get any response out of the screen even while it's plugged in, until the battery hits something like 10%. Might be that the cable thinks the Nook is charged when it isn't.
Another dead nook color after updating - any suggestions?
I too, have a dead nook color that has been my pride and joy for the past year and a half. Always running smooth without problems as I have gone from CM7.2 -> CM 10.1 RC5. However things changed for me when I tried to install the zip from SD card, using the latest CM10.1 nightly from 6/18, 2 days ago. Half way through the loading/install process the screen when black, and would no long respond or boot. No mater what I do, I can only get it to boot into recovery, using my trusty SD boot disc. That is when the errors start. At the bottom of the recovery screen it says:
ClockworkMod recovery v3.0.2.8
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
When I try to install zip from sdcard, the error I get is...
E:can't mount /sdcard
Without being able to mount the sdcard I can't figure out how to upgrade or fix my nook...
Any help would be much appreciated.... I Love My Nook!

I can only boot my device w/a "boot" sdcard in the slot...and with no ability to mount the sdcard, I can't install anything from it....
holding the power and home keys didnt work for me so I opened the nook up and unplugged/replugged the battery pack and it fired up immediately.

I also tried to partition my sd card using twrp.
Flashing of twrp seemed not successful using fastboot. So I unplugged the USB-Cable and restarted in recovery and twrp was there!
So I went further and tried to partition sd. Unsuccessful. Then I decided to give up and rebooted to system.
Phone screen remained black. I tried everything to boot phone. No reaction at all. No vibration, nothing. Only when I connect the charger the buttons light up for 5 secs. But no way to boot, not fastboot, nor recovery or system. Just nothing.
I tried then to disconnect the battery (It's a replaced battery already) but also this did not help.
No I really need help...
Unfortunately above links are outdated....
Has noone an idea what else I could try please??
