Yesterday, I decided to give CyanogenMod a try and installed cm9-rc2 in my Samsung Galaxy S (i9000). I all went fine at first, but then I had to reboot and after I inserted my SIM unlock PIN was greeted with the infamous "Encryption Unsuccessful" screen. I had never seen any mentions to it in CM's wiki, where I got my instruction on how to install cm9. Afterwards I saw lots of forum posts about the problem.
I tried to recover my phone by installing CM7 (via CWM) and Samsung's stock image (via odin). Nothing worked. All I got was endless boot loops, looking at the animations. I was convinced I had bricked my phone. I went though google and this forums. I found lots of solutions for preventing the problem, but none for solving it once it had happened.
In the end I came up with a simple solution which got my phone back to life. I'm posting this as I did not find it mentioned in the forums. Maybe it's not new and I simply didn't look hard enough. If this is so, I apologize.
As my internal memory was not recognized, I used the microSD card to host /data, just like mentioned in the many threads that explain how to prevent the problem. All I had to do was to create a second partition in my microSD card. I used gparted (I use GNU/Linux) to shrink my microSD partition and created a second one (with 4GB) formated using ext4. From then on, my microSD card filled the role of the internal memory when that is not detected.
I was latter able to install CM7 and CM9. Both worked. I'm currently running CM9 and have a very weird behavior. Every other time I boot the internal memory is recognized. As such one time I get all the apps that are installed in the internal memory, the other I get the ones that are installed in the second partition of the microSD card. In any of the cases, the boot costs me any setup I do of the homescreen; I always get back to the reset state.
Even though I love ICS, I think tomorrow I'm going back to CM7 for the meanwhile.
Hope this helps anyone.

I use odin to just flash stock rom and move forward from there. it also fixes datadata error and if you find the right file if your phone dont see odin, odin will fix that. If i can help you anymore let me know. I had problems also but now can flash roms and kernels

Hi,
I've searched the forums but haven't found a solution to my problem. I rooted my Nook Color (1.1.0) using auto-nooter 3.0. Everything worked fine, then I tried to flash to CM7 using CWM. When I subsequently rebooted, the Nook goes into a boot loop where it never gets past the "Touch the Future of...." display before it reboots.
I've can't get into ADB because the unit reboots before I can get access. Also tried booting into CWM (3.0.0.5 and 3.0.1) on an SD Card. When I do this, it shows the "loading..." display for a few seconds then reverts to the boot cycle. Also tried nooter 0.2 but same result.
Tried doing 8 successive boot cycles by trying to turn it off before it reboots, but no luck.
I've noticed that others have had boot issues also, but it seems that everyone else has been able to eventually boot back into CWM via SD card.
If anyone has any suggestions, I would definitely appreciate the help.
Thanks.
I experienced this exact problem and never did get it working. I was running Nookie Froyo on SD with overclock when it suddenly started rebooting. Doesn't matter if the card is in or out, it gets to the point you describe and reboots. All of the "restore to stock' tricks failed because it keeps rebooting, even when booting into CWM from SD. I ended up replacing it with another new NC and put the the first one in storage hoping I someday figure out the problem. I've never found anyone else with quite this problem. I'll be anxiously watching this thread!
Not sure whether I should start to panic because you never got it working, or feel relieved because I am not the only one to experience this issue
You can add another person who is having this problem.
Yesterday I asked Rom manager to boot into recovery and that was all she wrote.
The nook gets through "Touch the future of reading," then the screen flashes for a fraction of a second before repeating the process again.
Holding 'n' and power while booting also has no affect; and it seems to ignore whatever is in the SD card slot.
Got it working!
Not exactly how this worked but here is what I did.
First off I used another SD Card Reader Although the idea of using another card reader doesn't seem to make sense; I had seen it on another forum.
I also Used a new uSD card
Used Win32DiskImage to burn the image to the uSD card (had been using DD on a linux box)
The images used was the Clockwork Recovery image (2GB,) look around and you should be able to find it.
I also copied the removeclockwork.zip
This should be available with a google search as well
From there it just worked like it was supposed to. The nook booted off the micro SD card and I used the removecwr.zip
Hope this helps
Where to begin...
So I based my install off of this YouTube Video: youtube.com/watch?v=88qRbLLEAPQ and after I got done following everything to the T, I was not able to format /data. I feel this may be my problem. After doing all the steps minus that one I tried to install CM7 and it would boot the second time around in CM7 (Something I read was common). IT would get the the skateboard screen and then it would just stay there with the arrow continuously looping around and around. I let if sit for quite some time before I had to power it off.
I called up my buddy who told me I would more then likely have to install it manually with the Android Developer tools (Or whatever he called it). I did not have those tools so I kept poking around online. I found that sometimes the SD card caused problems so I bought a new 4Gb class 4 card. This was not the issue.
I poked around alittle more in CWR and I accidentally formatted /boot. The unit froze up so I restarted it. It booted into CWR just fine and after trying to wipe the /system, /data (Still not working) and /cache and rebooting, it has now just turned to a black screen that I can't even boot from a card.
Now before I just cash in on my protection plan, What can I do to get this running again? I hate having a paper weight sitting on my desk..
Thank you so much!
tl;dr, Tried to install CM7, can't format /data, tried new card and re installing, accidentally formatted /boot and now it won't boot at all.
Honestly, I can't watch Youtube at work so I am clueless what instructions you are following.
1. What version of your NC? 1.2? 1.1? 1.0?
2. What version of CwMR?
3. You tried to install CM7 in the eMMC or uSD?
I don't know which Nc it is... I just got it 2 weeks ago today.
I do believe that the cwr was 3.0.0.3 or something like that... it was supposedly the newest.
and it was the latest stable version of CM7.
My problem now is that my computer has totally crashed and it won't start in safe mode even. I am fairly sure it has something to do with having the files on my computer.. I just have to get that part figured out, then I can get the rest of it working..
Latest CW is 3.2.0.1 if I recall.
I know when I leave my imaged microsd card in my adapter on the laptop that the laptop won't boot. You don't have the card in an adapter on the system do you?
Also, I assume you are trying to install CM7 to internal memory?
You have to use CWR v. 3.2.0.1. Earlier versions will not wipe/clear everything. Do that and you should be ok....
If it has been around 2 weeks ago, then it most likely be v1.2 which you need CwMR v3.2.0.1, which reportedly fixes the format /data issue.
Give it a try again.
Ok, got the Nook to boot back to the Nook software. Won't get past the loading screen, but atleast it is booting..
I got my computer working finally after booting in Safe mode and deleting all the zip files and images from the computer. So now I am back to a clean slate.
Where do I get CWR 3.2.0.1? And then where do I get the CM7 latest release? I feel like I should be listening to you guys rather then listening to the YouTube video.. It was nice to see things happen on there, But it did not work for me.
Thank you guys SOOO much for having this forum and the "How to fix the black screen" tutorial! I would be lost without it!
I am at a loss. I got this working just fine and then started tweaking things and ended up jacking my NC and restoring it.
I wiped out and reformatted my SD card and did the verygreen method all over again. I want to run CM7 off my SD card. Everything went smooth and I saw no errors.
The first night I charged my NC over night and woke to found the battery drained and it wouldn't charge until I removed the SD card. After that I got the boot loop.
Came home and redid it all over. Once again it worked wonderfully until I restarted my NC and then it gets stuck in the boot loop again.
I have started fresh and have no idea why the issues. I have the latest stable and gapp. Am I doing something wrong in settings? Do I need to mess with ROM Manager at all if booting from the SD card?
Back up and running but still needing questions above answered.
Is there a thread that helps with CM7 or ROM settings after a successful install?
I just want to be sure I am not changing settings that are causing this. I downloaded Nook Tweaks this go around and not sure if that would give me issues. I didn't do this the previous times when I didn't have problems.

What kind of card are you using? Anything other than a SanDisk Class 2 or 4 can cause strange instability.
16GB Transcend Class 6. I guess I will search for a Sandisk Class 4 and see if that doesn't solve everything. One day it works perfect and the next it melt downs when I have made no changes. Maybe you are correct and it is simple as that.
I don't know how you doing but reading what you said ".... until I removed the SD card. After that I got the boot loop.", it doesn't make any sense, maybe you have done something wrong? because booting ROM off uSD shouldn't have any ill effect on the local internal OS.
You still have a boot loop w/o the uSD plugged?
What CM7 version are you using?
Also, are you using Rom Manager, or just Clockwork Mod Recovery directly to install CM7? Idk if things have changed, but when I was on an sd-card install, Rom Manager would always want to install things to emmc so it was easier to reboot into recovery and install updates manually.
I was also using an "off brand" sd card and would get force closes on apps. It might be possible, but I would suspect this is more of an installation issue than something with the card. That said, Sandisks are still supposed to offer the best reliability and performance.
You should only have a normal Nook Color OS come up every time you boot with the uSD out. It sounds like you may have flashed your emmc somewhere along the way.
I had a similar boot loop situation when i was trying to charge over USB with a dead battery (the nook kept restarting and running out of juice mid boot.) It corrupted my emmc CM7 somehow and it was fixed by reflashing once i had charged it from the wall plug.
Verygreen's method doesn't require rom manager.
Sorry for any confusion. I am not having any problem with the NC booting when I remove the card.
I just ordered a 16GB Class 4 Sandisk and I am going to give that a try. This current install is working fine but I haven't messed with any settings really.
Hi. Ok so I rooted my NC to CM7 sometime last year, and now with all the blah about markets not working and having to do more about it, not to mention the PIA it is to get books on, I decided to put it back to stock. Which apparently was a big mistake.
First I mounted an older version of clockwork to the SD card, then when I figured that out (having format data error) I did the newer 3.2.x.x one. So that went good, I went through the steps and reformated data and system, and then went to upload the zip from the choose zip part, but it says there are no files. So I backed out, took out the SD and put it in my computer(Macbook pro) to try to put it in again but it wont show up at all? I tried looking in Disk Utility too and its not there. Any ideas where my card is? What do I do next?? I have nook complete restore 1.0.1, 1.0.0 and nook color update 1.4.1 on my desktop, I thought I had 1.0.1 on the SD card.
I've been reading and googling all over, I can't find what could've made my SD card disappear?
Thanks, I know you must get these all the time and I really appreciate your help-
Ok I didn't do anything, but it just started up to the little silver N and is now sitting there? Is that a good thing?
Don't panic. The NC is very hard to permanently brick. From what you've described, it sounds like your SD card may have gone bad or been corrupted. I'd just try again.
The 'n' logo is a good thing, but if it hangs there, be sure you've followed all the steps carefully. That's typically a sign that /data wasn't formatted, though from your description, you got that step.
Sorry I can't offer up anything more specific. Do be aware that you can restore back to 1.3 if you don't want to go back to 1.01
It happened to me and what I did is plugged my sdcard into my android phone and format it and start over again.
I did that couple time during first attempt to install CM7 on my nook
Hope this helps ! Good luck!
Try plug it into different computer(s) along with using usb-adapter.
The Eausus Partition program works well to wipe/format cards too...
My apologies for what is (hopefully) a simple or obvious issue and shortcoming on my point. I've used xda to flash my very first custom ROM, and managed to get things sorted without having to resort to asking you, the assembled phone-modding-guru's but I'm at a loss and don't want to dig myself in any deeper and make more of an issue of this than it already is.
I've got a UK HD2 with a sandisk ultra 32gb micro sd (with a 2 gb partition) and the ROM, Android 4.0.4 On HTC HD 2 NexusHD2 HWA V2.7
All was good and I'd even managed to overcome the lack of internal memory by installing Link2SD and placing the new Apps on the SD card. All was good until this afternoon when I set up a recovery app (or whatever it was classed as) in Avast.
I kept getting a message saying that something had crashed then Avast started flagging issues and finally, things refused to connect to the WIFI - google chrome, the stock browser, google play store. I tried following some instructions on various forums (stop google from syncing) after typing out what the prompt was but then my broadband went down and I lost what I'd typed.
I tried to restart my HD2 but then it refused to boot up. I managed to find that this is called the Boot Loop and followed through this thread Please Help!!! HD2 Boot loop, making a recovery which I've stored on my pc (I took out the sd card and used an adapter to connect it) and used the zipped ROM that was on the sd card but alas, back to the boot loop.
I've checked the battery pins and non are bent, although the one on the right hand side does seem to be a tiny bit shorter than the other two (I'm talking fractions of a mm) and checked to see that I'd mounted the SD card.
So, I guess my question is, where to go from here?
Well I don't know if it was the ideal way to sort things but after following the instructions on another site, I managed to get rid of the boot loop but now can't access the apps through Link2SD...
For future reference, if anyone else is unfortunate enough to have this issue, have a go at following this...
pull the battery, put it back in, hold down call-end whilst booting to boot into to MAGLDR, launch AD recovery, clear the cache partition, clear the dalvik cache, clear the battery stats and fix permissions then restart, I have to at least clear the dalvik cache every single time I reboot ANY android nand rom on my hardware (LEO512-TELSTRA) otherwise mine boot loops or just gets stuck on the black background and green htc.
try also Fix Permissions under advanced and "wipe data/factory reset" options in the AD recovery menu's
I do NOT use EXT4 partition, there could be something screwy on your card though, try booting it up without your SD card in, if it boots then you know there's something crap on the card you need to clean up
I'm unsure about being able to post external links on here (this is my first post after all, and one borne out of panic!) so if that's a no-no then please accept my apologies once more but I thought that if this can help one person, it was worth me writing this last part!

Thanks but non of those contained anything specific to my problem - I've looked through each one at different times.
