My nook color recently got stuck on the boot screen for CM7 where the blue android text just chills out in the left corner. This happened right after my nook ran out of battery power.
I have gotten it to boot all the way into CM7 occasionally. However, it is not reliable at all, so I've tried to restore it to stock and reflash the whole thing.
I tried to do this by booting into recovery and then flashing the restore to 1.01 stock zip file, but when the nook rebooted it was still stuck on the android text. I have tried flashing everything related to restoring nooks, but to no avail.
I thought that maybe my CWR was broken, so I tried making a CWR sd card but even when I flashed the restore zip, my nook's boot still gets stuck on the android text.
What do you think I should try to do now?
You are able to boot into cwr though? If so have you tried downloading the stock image file again? Could be the file is corrupt.
I just downloaded it again and it still doesn't work.
I don't think that the problem is the zip files. I think that CWR is the problem since I've tried formatting /system and /data and tried repartitioning boot, but nothing happens...
I just tried to restore my nook to stock through ADB, but it still tried to boot into CM7. I guess that rules out CWR as the problem...
I also made an ext4 compatible CWR SD and tried the restore 1.01 zip again. This time I got past the android text and instead got to the grey android text from the rooted nook boot. However, it just sat there, stuck in a loop.
Odd, that even after wiping system and data that you'd have anything to boot into. You aren't leaving a bootable sd card in place are you?
I make sure to take out the SD card before rebooting.
Is it possible to check to see if CWR/ADB is actually writing to the correct partitions?
EDIT: I do not think that my nook is keeping any changes that I make to it...
I managed to boot into CM7 and I uninstalled a few apps and changed the max clock to 800mhz. Then I rebooted and eventually got back into CM7 and my apps magically came back and my max clock was reset to 1.1ghz.
okay that is very odd. Unfortunately I've never run into this or even read about it before. Hopefully someone here will be able to give you a tip that will help you fix this.
I've been having same issue for a week now. I tried everything I was able to find here but nothing is wokring. It seems like my nook became a read-only device. No matter what I do it goes back to previous stage.
I was running CM7 RC4 and system hung so I rebooted and that was it. It displays "Android_" on the bottm for about 10-15 sec and reboot.
I tried
CWR 3.0.0.5
- Repratition to stock nook.
- Getting error when I try to format system and data - I thought it was because CM7 was setting system to ext4.
- ADB and DD boot.img, System.img and copy Factory to mmcblk0p3
- Try to restore from back up I made
- Nothing works but goes back to boot loop
CWR 3.0.0.6 - One I got from CM7 install to emmc thread
- System format works
- Install latest nightly
- Restore from back up
- ADB can't find device - This is odd and couldn't find a way to fix it yet.
- Tried to install Stock zip but going back to CM7 boot loop
CWR 3.0.1.0
- Can't format data/system
- ADB to delete partitions and create them again but it doesn't help
- Tried all zip files to bring it back to stock - no go
- ADB to copy Factory.zip to emmc partition - umount and mount again then file I copied is gone.
- Deleted partitions and reboot but some how I got back to CM7 loop
I see people start to talking about CM7 boot loop issue. I saw this thread and man this is same issue I'm having! Let me know if you some how resolved this issue. I will do the same if I can find one.
Naw, I haven't resolved it yet...
I will post the solution if I do though!
Perhaps it's just a coincidence, but I am also stuck running RC4. Maybe there's some weird glitch in RC4 that makes the file system read only or something...?
I went from RC4 to stable with no problem. I did notice that CWR was not mounting the system and data partitions so I did have to do that when updating. Not sure why they aren't mounting automatically.

Download either the Rootpack, or the Clockwork Recovery image (1gb).
Next visit this link and download the 1.0.0 or 1.0.1 restore to stock files:
http://forum.xda-developers.com/showthread.php?t=914690
From this link you should also download the very last zip on the page. It is titled-flashable boot repartition zip. or something of the like. If you followed all these steps and still nothing, I would recommend flashing this as it can fix a completely screwed boot partition.
I had to use that last file after my hard crash. Seems that te /boot gets corrupted and tis seemed to fix it for me. After this you will probably need to do a full wipe and reinstall.
My order was...
rebuild /boot
reflash to stock
reflash to CM7
not sure why this worked...just did.

I tried this too but mine didn't come back.
Hmm. dunno. Maybe you can get samuelhalff to chime in...he was helping another guy out with something similar. searc in the threads for his name and your problem...wasn't to long ago.
edit---http://forum.xda-developers.com/showthread.php?t=1022941 this was the thread I was talking about...doesn't appear they came up with a solution.
I tried all the things you suggested guys, but nothing worked...
Although I think I made some kind of progress... I tried to dd stock boot.img and system.img files onto my nook and now CM7 just bootloops instead of hangs!
Hopefully we can get this sorted out soon, or else I may try what one member suggested about microwaving it so that you can get a new one...
Several users have complained that they get blank screens and cannot flash new roms to their Nook Color. And sometimes they end up in a recovery bootloop where it will do nothing but boot to recovery no matter what they choose in the boot menu. Sometimes this is due to corrupted partitions on internal memory.
DizzyDen has prepared some .img files that can be burned to emmc to repair some of these issues, and they work well. But some of the files are very large and it takes a little knowledge of adb commands on the part of the users. And some users cannot get adb working on their machines. So I started investigating other solutions, and I have made some tools that work that I hope are user friendly.
Dean Gibson has a thread that describes how to repartition emmc to set the partition sizes for data and media to the user's preference. He repartitions partitions p6 (data), p7 (cache) and p8 (media). In studying his zip, I figured out how to make his tool repair partitions p4 (extended), p5 (system), p6 (data), p7 (cache), and p8 (media). And I was able to add additional commands to also repair partition p1 (boot). I asked Dean's permission to post his tools as modified by me and he agreed. Thanks Dean!
So that takes care of partitions 1, 4, 5, 6, 7, and 8.
Partitions 2 and 3 are very special and one must be very careful with them. Partition 2 is 'rom', which holds information that is specific to the user's device (serial number, etc.), and it is used by the system to set flags for deciding whether to boot to recovery or not and set the boot count that is used to decide whether to do a reset to factory conditions (8 failed boots). Partition 3 is 'factory' and holds the factory.zip file used by the 8 failed boot reset (if you want to learn more about the 8 failed boot reset, go to my tips thread linked in my signature). It also holds a backup of the device information in partition 2. So it is possible to repair partition 2 if partition 3 is still intact.
A few users have somehow managed to flash Nook Tablet ROMs to their Nook Colors and really messed up partition 4. (Edit: and now I know how it happened, some idiot recommended that they remove the first line of the updater script. NEVER do that! That line is a safety check to make sure you are flashing to the right device. You can also defeat the safety check by using an old CWM that has the toggle, 'disable asserts'. Never do that either.) And since partition 4 is the extended partition that holds partitions 5, 6, 7, and 8, they get messed up too. To repair those partitions along with partition 1, use CWM recovery to flash the two zips attached below. Be warned that everything in emmc media (p8) will be wiped out, so you may want to back that up first if you still can. The first zip to flash is 'NookColor-emmc-repair-partitions-1-4-5-6-7-8.zip'. It will recreate those partitions on emmc. As soon as you have sucessfully flashed that zip, you must reboot the Nook Color back to CWM so that the updated partition table is read by CWM. Then you need to flash 'NookColor-emmc-format-partitions-5-6-7-8.zip' (partitions 1 and 4 do not need formatting). It will format the newly created partitions to the correct structure. Now you can use CWM to restore an earlier nandroid backup or flash your favorite ROM (including stock, get version 1.4.3 that I have modified to be flashable with CWM here, or DizzyDen has posted some excellent 1.4.1 stock ROMs here). If you are going to flash a stock ROM, you must be sure to use the format zip or the stock ROM will not boot properly.
If you are in a recovery bootloop, the first thing I recommend trying is to use my CWM version 5.5.0.4 bootable SD that is discussed in my tips thread linked in my signature and has been modified to help get out of some kinds of recovery flag bootloops. If you are in a recovery bootloop that just hangs, it may get you out of it after exiting my CWM with the 'reboot' command in the menu. But if you are still in the loop after doing that, it may be because your device info is missing or corrupted in partition 2. It will not boot to a ROM without this info. (Specifically, it needs a file in /rom/devconf named DeviceID. It is a text file with your 16 digit serial number in it followed by a line feed, 17 bytes.) Try flashing with CWM my 'NookColor-emmc-repair-partition-2.zip' attached to this post to recreate that info. But I recommend this as a last resort, since messing with that partition is risky. That zip will recreate the partition, reset the flags and copy your device specific information from partition 3. But your partition 3 must be intact for this to work. If it is not, the zip will abort and do nothing.
Additionally, for those that do not want to use CWM, I have made a bootable SD that has an older version of TWRP here. Newer versions of TWRP will return an error message when trying to flash these zips. It also has been modified to get you out of some kinds of bootloops.
Two points of information. First, I have included a temporary copy of CWM 5.5.0.4 on the boot partition of my repair so that if tries to reboot to emmc before you put a ROM on it, it goes to CWM. It will be removed as soon as you restore a backup or flash a ROM. Second, the new partition scheme created with my zip is for the original Nook Color's 1GB data and 5GB media. If you want one of the other schemes (5GB data/1GB media or 2GB data/4GB media) go to Dean Gibson's thread and flash his zips after you have repaired your system with mine. See his thread here.
I'm adding a little extra information about emmc partition structure for those interested. With any MBR disk there can be a maximum of four primary partitions. So to have more than four partitions the last primary partition is created as an extended partition so multiple logical partitions can be made inside it. The emmc structure is: p1 (boot, fat, primary), p2 (rom, fat, primary), p3 (factory, ext3, primary), p4 (extended, going from end of p3 to end of the disk), p5 (system, ext2, logical, inside the extended), p6 (data, ext3, logical, inside the extended), p7 (cache, ext3, logical, inside the extended) and p8 (media, fat, logical, inside the extended).
You save my nook color
Thank you so much. My serial number and other information were recovered successfully. Without those information I could not boot into any rom. If you cannot boot into ROM after following the first 2 steps, try recover partition 2. It works for me.

My nook has been stuck in a "will not boot" state for about a week. I could run CWM and cyanoboot, but when ever I tried to boot CM I would get stuck at the "loading..." screen. I tried loading both CM7 & CM9 but neither one would boot.
I ran both repair scripts, reloaded CM7.1 and success!
Thanks Leapinlar! :good:
THANK YOU!!!!!!
Right from my 1st install I couldn't get the bar at the bottom of the screen, which made using the Kindle app more than a little difficult. This finally cleared everything off so I could start with a clean slate, and BINGO! I know have the bottom bar on all the screens. I assume when I go in to the Kindle app it will be ok now also (I just have to format a 16gb microSD and put in the Nook Color 1st).
I can't thank you enough!!!!
Ugh! Tried this method too, and I still cannot get the nook to boot into CWR or CWM. I tried the 8 boots thing too, but I don't know if I ever did it right because I have cyanogen mod installed on emmc. Not sure how to repair the partition if I cannot even boot into anything that allows me to flash the zip to the chip. I thought it may be the sd, but the sd cards work on my other nook. I have now basically dissembled my nook color trying to find any other solution I wish I knew what happened in the first place.

Did you try my version of the CWM bootable SD card? It is on my tips thread and has been modified to boot in certain types of recovery bootloops. Unless you get CWM running you cannot flash things to internal memory. And depending on where in the boot process it hangs, you may not be able to get adb working to put things there either. And the 8 failed boots will not work unless you have stock recovery still on emmc.

Yup. Tried the card. I believe I replaced the emmc with cyanogenmod back in the day. Starts, goes to loading, turns black, then done. Cannot do anything after that. Bummer, sounds like it is actually toast.

If you can get adb working while it is sitting there black, you can push the stock recovery files to partition one. Then you may be able to do the 8 failed boots. You can extract the stock recovery files from my zip in my tips thread.

Worth a shot. Have nothing more to lose other than time. Maybe adb will work with you card in it. It didn't work with everything else I tried.
OMG OMG thank you soooo much for this thread , you saved my reading addict self from going insane ......
You've done a great job on collecting all of these useful things, especially for those who are stuck with their Nook Color boot looping. (I was once that guy) Dean helped me out with his data zips as well way back! Thanks for all this! :good: :victory:
Much thanks, leapinlar. Restored a nandroid with TWRP that was corrupted and lost my boot partition. I used your first 2 repair zips and I'm back in business. Your many contributions are greatly appreciated.

OMG! Thank you so much for putting this up! Back at the beginning of the year I was having problems with my NC not going into USB Mode and only showing a black arrow when trying to load books and following this finally fixed it. Great write-up and instructions, thanks for the hard work.
I've been trying to restore my NOOK for about 2 weeks and this post has gotten me the farthest but i'm stuck at the point where my nook will start up, the "Read Forever" splash screen will come up and then it attempts to recover the system since i see an greenish Android screen come up for a second and then i get an error screen saying "Install Failed" with an image of a nook with an exclamation point in it's screen. I'm assuming i've really messed the nook up but here is where I am.
I've reformatted the partitions using your 1-4,5,6,7,8 zip
Rebooted to recovery
Formatted partiions 5,6,7,8 with your zip
Flashed your 1.4.3 stock rom
At this point I can't get any further since it appears something else is wrong and i didn't want to attempt the reformatting of partition 2 without asking if there is anything else i should try. Any help would be appreciated.
Thanks

Do the partition 2 repair. That is what is messed up and causing the reboot.

Oh, that is really bad news. That means your partition 3 is corrupted and there is no way to retrieve your device info, like serial number, etc. PM me and maybe I can help you get it partly working, but much of the device info is lost if that partition is truly corrupted.

During reboot it should automatically go to CWM because everything else is wiped. The boot menu only lets you make the first choice because that is all that is there, everything else is wiped. You need to continue to use the CWM to flash the format zip next. Then you can flash a ROM. If the CWM that pops up is not working, use the bootable CWM SD.

Thx for replied, the Nook just stock on loading and it won't let me do anything except for power up and down
(For reference, I have a MAG2GA FW v6 dated 10/2012) -- yes, I have access to CWM and ADB
Had verygreen's CM11 (1-18, eMMC install) on my HD+ and it was working without any major issues -- came back home one day and the screen was frozen. Did a power + N button reboot, and now the CM logo on boot spins incredibly slowly (completely hanging at several points). After a few minutes it will either bootloop or get into CM11 -- if it does make it into CM11, the system will be very unresponsive and eventually reboot on its own [no matter what I select].
Booted into eMMC CWM 6.0.4.6, formatted /system, /data and /cache and reinstalled CM11 1-18 + PA GAPPS. On reboot, I see the exact same behavior (slow/freezing CM logo, eventual bootloop). When it does sometimes make it back into CM, I see my widgets / wallpaper for a brief moment before it bootloops again, implying that my format/wipe in CWM did nothing...?
I then booted into bokbokan's CM10.1 I had on a MicroSD lying around -- I installed the eMMC brick check app from there (which checked out fine, including a test on the full 16gb). I'm trying to do an ADB push now of leapinlar's NookHDplus-factory-2.2.0-plain-stock.zip so I can install it and try to get it replaced under warranty but it either [tried both SD-based CWM and eMMC-based CWM] :
1 - hangs forever (implying some issue with my internal storage)
2 - says transfer complete, but when I navigate to /sdcard/0/ I don't see it
3 - the one occasion I did manage to transfer stock back over and the system could actually see it, I got a '"Failed to retouch '/system/lib/libemoji.so'" error when installing (and yes, I'm formatting /system every time)
In additional, the eMMC CWM behaves very erratically, sometimes taking over a minute to navigate through folders or respond to a volume button click. Pretty sure my internal storage is damaged somehow.
It seems like no matter what I do in CWM, my HD+ continues to try to reboot back into my old CM11 installation. Any thoughts or ideas on what I can do next?
Edit: Okay, so using a 4GB SD card image, I tried to erase /system, /data and /cache and flash cm 10.1 and twrp just to see if anything would stick. Removed the SD after flash, reboot, and the system goes right back into CM11 boot loop. Trying to reboot into TWRP brings 6.0.4.6 back up -- looks like nothing I'm doing will stick. Brought up ADB shell and ran "mke2fs -T ext4 /dev/block/mmcblk0p8" to wipe system, still reboots back into CM11 no matter what I flash in SD CWM.

I have the same issue, but on my HTC One S. My eMMC chip: MAG2GA.
Looks like its TRIM brick.
I can't wipe or install other rom, and recovery allways say "E:/can't mount /data"
My system works well, but after reboot the system returns to its previous state and all new data (SMS, calls, files) delete.
All it happens after 27 January after installing nightly update for CM11
Leapinlar has the knowledge and info on fixing the partitions. Might be just refreshing them up might fix it. Trim bug can also cause physical damage... don't know which that could be here if its it.
I've played a few minutes with the 29th(?) nightly and had not received this problem though that build had quite a few issues for me. So Korshun could be on to something.
Just swapped it instead -- seems like physical TRIM damage, given that nothing I changed [even writing 0s to disk] would stick.
I have a new LG Optimus L90 (D415) with stock 4.4 ROM, and TWRP 2.8.0.0 (and previously, Philz 6.58.7) for recovery. Obviously, the phone is rooted and now has an unlocked bootloader....
My problem is that neither recovery will back up (or even mount) "/data". Note that I put that in quotes because, without having "/storage/sdcard" or something in front of it, I presume that it's an internal folder and not something to do with the external SDcard.
My first guess would be a problem with encryption, because both the phone and the external SD are using it -- and I never get asked for the password. Either way, the actual error in TWRP says "E: Unable to mount 'data'", while Philz says it can't access /data/philz-touch for the .ini file.
I've made several Google expeditions to find the answer, and have come up empty-handed with all of them. I've seen all kinds of fixes, from claims that I have to run chkdsk against the SDcard, to backing up the entire /data partition with a tar file and reformatting it with command line nightmares.
I'll do what I have to in order to fix this, but I'd rather not embark on an experimental goose chase. Any ideas?
I have this same problem. But only for wiping and flashing.
I have no idea for fix if backup also not working !! (Noob)
1.TWRP click backup. Select all except SDcard.
Finish backup.
2.go to Wipe menu.>advanced wipe>select all except System and Sdcard.
Wipe.
(It will skip the error files)
3.Install menu. Select ROM to flash.
Was what I did.

I'm not flashing anything, yet. First I need to make a backup of the entire phone (not including the SDcard). That way, if something goes wrong, I can just restore my old, working configuration -- all at once -- and start over.
I can back up and restore apps individually, using Titanium Backup. But what I need here is a Nandroid-type backup... and that generally has to be done from the recovery partition. There is one other way to backup everything, using a laptop/PC and ADB. But I've never tried it, and it wouldn't protect against a ROM meltdown.
Solved, somewhat...
So I did some further experimentation concerning this error. I did a test run to install CyanogenMod, and I found that I couldn't even factory reset certain partitions because of these "Unable to mount /data/" type errors.
What was ultimately the problem? The encryption. Once I decrypted everything, TWRP was able to see, mount, and backup, those partitions.
But I was under the impression that TWRP handles encryption, e.g. asking for the password, or some such. I mean, how can you do a Nandroid-type backup on a phone, if no recovery can mount those kinds of partitions?
So, for the record: "E:Unable to mount" was definitely due to the encryption being turned on for my internal storage. Thus the solution (so far) is to decrypt storage. A wretched solution, but at least it works for the time being.
BTW, In furtherance of this research, I formatted my internal SDcard to NTFS, just to make sure it wasn't misaligned or whatever when it was just FAT32. And I discovered that NTFS takes forever to format (32GB on the order of a couple hours)., FWIW.
The plot thickens. It may not be sufficient just to undo encryption, there may be something wrong with the way that partition was created, or otherwise is constructed.
Even though I now am able to mount /data, I'm not able to format it.... in TWRP it says something like "unknown filesystem 'auto'".
But there is a thread here that describes using Philz recovery to unmount and then format this mess, and I'm about to try it, I just have to flash Philz in place of TWRP. Now let's hope this version works without issues, because I'd have little recourse if things go bad there.
Hello All,
Long time lurker, first time poster (and, as usual, asking for help)
I have a Samsung Galaxy Tab GT-P1000, stock, rooted. Was installing an app yesterday from the play store, when the device rebooted and now it seems to be stuck in a boot loop.
At first I was afraid that it was the dreaded internal SD card corruption issue mentioned here: http://forum.xda-developers.com/showthread.php?t=1463756
However, when connecting with adb, I was unable to locate any references to the error mentioned in the post above :
Code:
<3>[ 4.802004] mmc0: error -110 whilst initialising MMC card
(Also tried the alternative option to list contents of /dev/block and was able to see several references to mmcblk)
Having said that, I haven't yet tried a wipe data/factory reset from the stock recovery because I am not sure if this will wipe my internal SD card contents. I do want to try to save/ copy out my pics etc. if there is a way to do this at all prior to wiping it. (And yes, I am kicking myself hard for not having backed this stuff up.)
I guess what I am asking for is:
a) Is there a way to recover from this without a complete device wipe?
b) If I do need to wipe from recovery, will I lose media/user data on the interal sd card?; and
c) If so, is there a way to retrieve all this data to a PC prior to wiping?
I have also attached the adb logcat file recorded during the bootloop.
Thanks All!!

I guess this forum is not quite as alive as some of the others, which makes sense considering the age of this device.
In any case here is a quick summary of what I went thru to successfully get the device working again. (and I still have all my pics/videos )
a) Answer to my first question below - After a loooot of googling, I couldn't figure out a way to recover without a wipe.
b) Answer to my second question - You will NOT lose data on your internal SD card when you do a wipe from (stock) recovery.
c) Answer to third question - There may be, but I was unable to figure it out. I'm fairly certain you can mount the internal SD manually from ADB if you have root and attempt to pull your files to your PC, but my device didn't have a rooted kernel, so I couldn't quite get this done.
Anyway, my other issue was that my Stock recovery was unresponsive as well. On selecting the wipe option for example, the screen would clear itself of all text and just display the Android w/ Exclamation background. I attempted to flash CWM recovery based on the steps in this thread: http://forum.xda-developers.com/showthread.php?t=2430190
However, I ended up with a corrupt screen when attempting to access this new recovery. (Don't know - May be because of improper rooting?)
I was able to successfully restore the device by flashing the stock recovery and ROM based on this thread http://forum.xda-developers.com/showthread.php?t=1133590 ,following the instructions for un-softbricking .
When I booted into recovery and attempted to wipe/factory reset, I got an error.
Code:
rfs format failed on /dev/block/stl10
There was an additional step I had to take, which is clarified further below in the same thread. http://forum.xda-developers.com/showthread.php?p=27979493#post27979493 , which is to flash dbdata as well.
Doing this let me successfully wipe the device, which in turn let me finally get out of the damn bootloop.
Anyway, I hope all this helps someone. Thanks for being a great resource as usual XDA! :good:

Hi, guys.......new to the process....rooted my galaxy tab p1000 2.2 froyo with z4mod.
Then initially I installed cwm with ROM manager for galaxy tab T because there wasn't any specific model of cwm for p1000.
But but when I switched off and booted recovery, stock recovery always came......I could access cwm only through the ROM manager ("boot into recovery")....and that too if i choose any function it starts to load and when I press home twice it says "replacing stock with cwm" and that goes on forever...
So I installed cwm with Odin as I couldn't access functions like "install" in cwm without going into the loading phase.....but as the process in Odin finished, my tab started to boot and at "galaxy", the sceen got all pixalated and it went till " samsung " and the whole process looped........ Help!
