[Q]Nothing will boot from eMMC

Hi all,
I was hoping someone would be able to help me out as I am seemingly in a bad situation. I received my Nook 2 days ago and rooted and tried out a few different ROMS to get a feel for the choices. In any case, for some reason my Nook no longer appears to be booting anything from internal memory. Any ROM I have tried (stock included) has failed to boot, but I can get the Nook to load CWR with the memory card in. When I say failed to boot, I mean a black screen. Like no response from the device at all.
Please if anyone can help it would be greatly appreciated, I really dont know what else to do or what the problem is.
Thanks,
Michaelangelo

Get the nook restore to stock zip and the boot restore zip. Flash those both back to it. Also, make sure you are wiping, System, then Data, then Boot beforehand. And wipe both Dalvik and cache. Nook Color is nearly impossible to hard-brick (in the sense of being unable to recover from it).

This happens because the boot partition is corrupt. This is usually the result of you formatting the SD card with CM7. Due to a bug, when you try to format the SD card, it will wipe out the boot partion as well. Just restore the boot partion and you will be OK.

Is there a way to do that when the screen is not working?
An automated install or do we just push buttons as per the same task on another nook and hope

Okay, so I understand that the problem is that CM7 changed around the boot partition files, that makes sense as that was the last thing I could get running on internal memory. When I was flashing HC v4 to EMMC I also flashed a boot repair, and that still did not work. I cannot seem to find a boot repair file for stock, where do I get that.
Sorry for the noob questions, and I am definitely trying to use search the forums for answers before i ask these questions!

We have life!!! I found a stock boot restore file and it turned out to work, I am back to stock again. Man this is sure a learning experience. I have been flashing my Evo for a while now, but the nook is a different beast all together.
Thanks for your help all, I think I am good from here on out!

You get a microSD card with CWR and the both .zip files for the stock 1.1 and the boot partion, then pick install .zip from SD card and flash both files. When done, take out the microSD card and your NC should be able to boot normally...

How do you know it's booting into CWR on the SD if the screen is not working?
If your screen is not working when booting from a SD card, then.. maybe there is something wrong with your nook???

If I boot nooter 0.2 then the USB plug goes green which apparently indicates booting. Oh and OMAP3630 shows up for a second on booting too.
Thing is I didn't do anything to break the screen and there is no physical damage to the unit. so it's just weird

I thought I had the same issue because of the screen being blank. That said it is highly unlikely your hardware ( ie screen ) is bad. I was able to get mine working correctly last night doing what is mentioned above. However to get it to work right booting into CWR via a bootable sdcard I had to make a new bootable sdcard from the one I had. Not sure if something was corrupted on the card I was trying to use or what. But as soon as I made a new bootable sdcard and put it in the device and powered on it boot right up to CWR off the sdcard like I needed so I could fix it. So my suggestion if you can is take a totally different sdard fro the one you have been using and make a new bootable sdcard and give it a shot.
BTW with no card in the device hold the power key down for about 20 secs to make sure it is fully powered off. Even tho your screen is blank does NOT mean it is fully powered off as I learned real fast last night when I tried working on mine. I thought it was off from the night before but it must not have been because I put a bootable HC sdcard in it and when I plugged it in I got a msg saying battery to low to power on plz try again in 15 mins. About 10 mins later I came back and it was finally powering itself on and booting into HC off the sdcard. So I let it fully charge and then start playing with it to finally get it back up and running again.

NC boot up problem

I flash my NC with CM7.0, now everything seems working fine, but I found there are sometime(not always) it stuck at boot animation, after touch the future of reading, it just stuck there.
this happens alot when I turn it off for long time, I am not sure what is the problem seems it doesn't happen every time.

I am having the same problem, but noticed that if i take the SD card out the NC starts normally. so i am figuring somthing is left on there from the install that is causing the hang up.... or maybe it is something else and i am too naive to realize what it is. Any help would be appreciated.
Using CM7.0 stable.

I tried to install CM7 on my nook color and i didnt follow the proper method and instead saved the CM7 file to the root of my sd card and installed the zip through clockworkrecovery without wiping or cache and now im stuck at the android boot screen. It isnt the CM7 skateboard android boot but rather the plain android root boot screen. If anyone could help it would be helpful thank you! IM crying right now about it

Hold power+n for 10 seconds to turn off
Clockwork bootable sd card, wipe system/data/cache (not boot), install cm7 from zip, install gapps from zip.
This is for a clean fresh install.
I made the same mistake yesterday going from stock nook to cm7 on nook #3 (so used to flashing nightlies on the other 2 i forgot to wipe system first)

[Q] Problem with paranoidandroid

Hello,
first of all sorry for my bad english. I have a problem with my phone and really need your help.
So, what happened:
yesterday I installed baseband 521 V20s and Django Manouche custom rom. I didn't like the rom very much so I decided to move on an another rom. I chose ParanoidAndroid 11. I installed it from CWM, like it should be installed, but then I got a problem. The phone stucked on boot animation (image of paranoid android in the middle of the screen and little androids falling down like raindrops). And nothing happened for 5-6 minutes so I pulled out the battery and turn on again a phone. Then I got message that goes something like this: "optimizing applications" and when it finnished, I over again got boot animation and nothing happened. I waited for 10 minutes, and then finally the boot animation stopped and screen went in black. It respond to touch (soft keys got light when I touch phone), but black screen doesn't disapere.
So, what to do? I didnt do nandroid backup, I erased Django rom from internal sd card so I cannot flash back to it via CWM. The PC doesn't recognize the phone any more so I can't put new rom to internal sd card. I did, however, manage to put the rom to external SD card, but in CWM recovery, it says that "Can't mount sd card".
What should I do??
I hope that you understand my description of problem and that you can help me.

Easiest way is to boot into CWM. Under "Mounts and Storage" choose "Mount USB Storage". You should be able to copy a new ROM to the internal SDCard from your computer.
If that does not work, search this forum for guides on how to use "Smartflash" or "NVflash".

Reflash ParanoidAndroid after a full wipe (cache, system, data, dalvikcache) without flash other kernel or gapps. Then reboot it should work

When I do that in CWM, Windows ask me to format card. What should I do?

Try a factory reset in CWM. (Or wipe /data and /cache).
This should hopefully fix your boot loop.
And when windows asks you to format the card then do it.
Could be that it got corrupted (which would be the reason why CWM can't mount it).
You will loose all data on it, but it looks lost, anyways.

What options should I choose? What "File system", "Allocation unit size"? If I use default options (Fat and default allocation size) Windows pops up this message: "Windows was unable to complete format."
Should I try with another sd card?
Anyway, I did some research and find out that I could use adb to push rom to the phone. But, I stuck there also. I finally found out how to open adb (and even what is it) but when I use command "adb devices" to test if it works, I got "List of devices attached" and nothing else
I know that problem is in drivers, but I dont know how to resolve it.

I finally solved it.
Thanks to PaulOBrien and NVflash.

How do I reset my nook hd+ back to before I rooted it?

leapinlar: Ask the question on the forum. I don't like using PMs.
Recently the update allowing google play store somehow bypassed the anti-update thing on my nook, so now I can use play store on the nook home, but the update removed my root but kept the android system home.. It uses a lot of ram, which i'd rather have free to play games or other resource heavy apps on.
I know I have to get my nook to start unsuccessfully 8 times, but I don't know how I go about doing that, can I get some help?

If you want to do it the easy way, just interrupt the boot by turning it completely off (hold power button for a few seconds) while booting eight times in a row. It will take you back to some version of stock, usually 2.0.0 or 2.0.4 then upgrade again to 2.1.0 when you register again.

After my HD+ locked up when I created a "Guest" ("child") profile and I had to do the 8-reboot process, after upgrading to B&N v2.1.0, I experimented with alternate button combinations at power-on. If I held the "n" button when pressing "power", I got a prompt that allowed me to do a factory reset.
Whether that is part of a later B&N recovery module, I can't say.

That factory reset just wipes data, it does not reinstall the ROM. He probably needs to reinstall the ROM since some of the broken symlinks may still be in /system.
Power + n takes you to stock recovery, which, without other parameters being passed to it, asks if you want to factory reset.

Thanks for the help!

I'd like to return my Nook HD+ to stock, too. It has a Cyanogen mod that precedes that startup, and I think that's getting in the way of the 'eight reset' mechanism for a total factory reset to stock software.
Is there a bootloader, system, and gapps zip that I could just flash from an external SD card that would do the job? Seems like there was, at one time, but it's getting very difficult to find them. Any ideas for a quick factory reset (not a wipe, but a complete reset to original OS?).

Go to my HD/HD+ CWM thread linked in my signature and flash the plain stock zip from item 6 there and follow that with a factory reset by CWM.
And it was not the cyanoboot that prevents the 8 reset, it is because when you originally installed CM you also replaced the stock recovery on internal memory with CWM. Stock recovery is needed for the 8 reset to work.

Hi there,
I have a device that is also candidate for unrooting to stock. The thing is that I have tried both CWM and TWRP on bootable SD to try and fix the situation tith the apropriate zips but unfortunately none of them can mount sd ot any internal memory for me to reset.
Maybe I should also add that the device is charging without turning on except if there is a proper bootable sd inserted.
I presume a rescue bootable SD of OEM type could bring the device back to life.
I`ll apreciate any help.

When you say a candidate for stock, why? Is there something else wrong with it? I am just trying to see if it is bricked.

Maybe Bricked is the situation. The device is charging (the green light is present when plugged to the charger or USB ) but the power button can no longer start any visible boot process on the screen.
The story of the device is nearly the following:
I was using the device for a long time rooted with installed CM updating even with over night builds from time to time.
Once I had a problem booting properly after update but easily booted to TWRP and restored the previouse update.
A week ago the same situation occured, after an update procedure I left the device plugged to the wall charger and on the morning it was stuck on the CYANOGEN universal boot logo. No way found to boot to recovery found.
I figured the recovery has gone bad. Started to prepare bootable SD to try and fox the mess somehow, but could not do the corect procedure of preparing a good bootable SD many times. The only time I successfuly booted CWM recovery from SD I tried to install a zip with CWM recovery and as far as I remember at that time the bootable recovery was able to mount another SD wile it was booted on the device and the zip installed with success according to the software. Sadly after a restart the device was as is, stuck on the bootloader logo.
After 2-3 times successfuly booting both CWM and TWRP recoveries from prepared SD card, doing nothing at all that can alter the device, just tried to see how to mount any usable memory, the device stopped visualy booting without an SD.
Thank you for the reply, hope you can add some wisdome to the happy end

It sounds like it is bricked. If recovery said it installed successfully and it still will not boot normally, it is usually what that means. By bricking, I mean internal memory has become read only and nothing can successfully be written to it even if it said it was successful. Your probable only option is to use a noemmc version of SD CM. Search the dev forum for that term.

No, it is probably from running CM11. That has a history of bricking devices with the faulty emmc chip due to applying trim automatically.

[Q] NOOK HD+ Stuck On NOOK boot screen

Nook HD Plus has been running great. Cyanogen running fully on internal memory with no issues. I was using TWRP and wanted to go back to CWM. So I flashed it and all seemed fine. Then I rebooted, and now it is stuck on the First Nook Splash Screen. I have tried to reinstall everything using a bootable SD card but still will not get past the Nook Screen. I can use the SD Card to boot into CWM and it takes all the installs just fine, but still stuck on the Nook Screen. Any ideas??? I have tried to install everything from stock to Carbon with the same results.

I have not. I did find out that the main issue is the internal drive was somehow formatted and that is why it will not boot properly. Not sure how it happened, but I think the main bump here will be to try and reformat the drive so it can load the bootloaders properly......it works with the SD card because the bootloader files are on the SD.....driving me nuts.

Try and install stock plain rom and let your device charge (must be turned on!) for 5 hours.

Beware that two of the HD+ partitions (see section #16 of http://forum.xda-developers.com/showthread.php?p=34168454#post34168454 for a complete list of partitions) namely /rom and /factory contain your device's unique factory-installed data such as WiFi MAC address, encryption keys, etc. You'd lose all this data, without which your HD+ cannot run, upon reformatting the entire drive -- unless you know how to backup and restore them.

Actually before doing any of those, you will always need to select the wipe data option when you boot to the CWM Recovery. Since you went from TWRP to CWM, you'll need to wipe it, and then flash it. Try that and see if it works.
