OK, for everyone that is getting the errors when trying to flash system and data, getting stuck at N screen, etc I may have a solution to the problem. Please check out this thread:

http://xdaforums.com/showthread.php?t=942324&page=2

For me my partitions were screwed up which what was causing my problems. There is a zip that is supposed to repartition your nook from CWM but it never worked for me even though it looked like it did it successfully. I had to DD over a good working image of the partition that was screwed up for me and then once that occurred I was able to factory restore it.

So the first step for any of you having this problem (get error when trying to format system or data, or getting error 0 when trying to copy the recovery image) is to boot into ClockWorkMod recovery via a uSD. Then once in connect you nook to your PC and adb to your nook. Go into adb shell and run this command:

fdisk -l /dev/block/mmcblk0

Your output should look like the following:

Disk /dev/block/mmcblk0: 7944 MB, 7944011776 bytes
255 heads, 63 sectors/track, 965 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

If it does not, that is most likely the source of your problems. Please post the output and then we can figure out where we need to go from there.

I'll take a look at the link and read through the information provide. Thanks again.
[Nook Color Android Development] JoJa15:
Ok, I am almost positive you are experiencing the same problem I was. To fix it you will want to use fdisk in dab shell to create the missing partitions. While I did not do it parted in the adb shell has a recovery option that may find your missing partitions and recover them.

If you use fdisk you may need a copy of the image of of the ext3 partitions. I messed mine up so bad that when remaking them they came out as ext2 partitions. My mmcblk0p4 partition also extended to 965 instead of 935. The good news is that with frisk I was able to exactly recreate the partition layout and everything is working great now.

If any of the above is confusing let me know and I will try to create detailed instructions for recreating your missing partitions.
[Nook Color Android Development] Humanio:
Thanks again. I read through the forum and ran fdisk with similar results. I also downloaded the mmcblk0p4-logical.img from that forum but I'm a little confused as to what to do from there. I understand that you have to DD the image, but should I be doing it from CWR?

Should I be using it at all if I'm may need a copy of ext3 as well? I'm going to wait to hear back from you before making the next move.

I currently have a working Froyo uSD and as well as a CWR uSD which I used to run the fdisk -l command initially. Although I've performed DD's before I'm a little confused as to what to do after Fdisk. Should I still attempt to DD the mmcblk0p4 thgouh CWR or Froyo? I assume if I toss the image onto the CWR uSD I will have to mount the SD card for adb to find the mmcblk0p4.img correct?

Thanks again for all your help, I'm really happy to finally make some progress.

-humanio
[Nook Color Android Development] DizzyDen:
OK... you will be using CWR boot SD.... put the img I provided on the SD and boot NC with it... in adb DD the image over to /dev/block/mmcblk0p4...

dd if=/sdcard/mmcblk0p4-extended.img of=/dev/block/mmcblk0p4

that command is assuming you did get the file I uploaded when troubleshooting with John and you haven't renamed the file... change the if= portion as needed if the file name is different.

You should then have the correct partition layout.... try the 8 failed boots and see if it doesn't work. And no, I don't think you need to mount the SD to see it in that mode... if you do... just use CWR menu to mount it.
[Nook Color Android Development] JoJa15:
Follow what DizzyDen posted above. Also please post your output from parted using the print statement. I want to see if your 6 and 7 partitions are ext3. If they are not you will need images for those to copy them over and make them ext3. Once you get to that step you should be able to do the 8 failed reboot step and have a factory fresh nook. If you have any problems at that point do the factory data wipe (boot into recovery with no uSD card in the slot). My nook kept rebooting at the all white nook color screen until I did that after the factory restore.
[Nook Color Android Development] Humanio:
Oh man I owe you guys big time. I went ahead and booted froyo, tossed the file in the sd card. DD'ed the image, and did an adb reboot and successfully booted back into my nook partition complete with root and everything how i had it prior to the mess.

Thanks again for all your help. I learned a lot of things along the way and I definitely could not have done it without your time and effort. I'm going to spend some time with my Nook before playing around with CM7 again. :) Hats off!
[Nook Color Android Development] DizzyDen:
Cool... glad we could help and get you sorted out... well your nook anyway ;)... glad its working.
[Nook Color Android Development] JoJa15:
That's awesome! A few days ago I was in the same mess and knew nothing. Fortunately with the help of dizzy I was able to get back to working. I am so glad that I was able to help someone else out.
[Nook Color Android Development] Humanio:
I'll make sure to pass of this info to anyone else in similar trouble. Its nice to have the Nook back again.:)
[Nook Color Android Development] uEih:
Got this back from 1.2, but i can't get passed the initial setup because it has problems registering the NC with the account so i went through Skipping OBBE but i can't add my account and register my NC. Anyone know what i can do?
[Nook Color Android Development] stolenmoment:
Nice and clean!

Thanks for this! I had autonootered and MRP'd my 1.1.0 NC, then went to using CM7 from an SD card, mostly abandoning the stock software. I used the procedure in the OP to reflash to stock, then applied the 1.2.0 update manually.

Smooth as silk.
[Nook Color Android Development] jblues1969:
Tried and failed

Well, I've tried and failed with this several times.

The first time, I wrote the img file using winimage and it booted to the SD card and when I tried to 'apply update from SD card', then 'Yes - Install update.zip from SD card', it told me 'E:Can't open /sdcard/update.zip (No such file or directory)'.

Then I reformatted the SD card and imaged it again, now it won't boot to the SD card at all.

Any advice?
[Nook Color Android Development] jblues1969:
OK, the instructions in the original post on this thread are WRONG.

Shutdown the Nook Color

Put sdcard in the Nook Color and press the power button

Press the volume down button so you highlight the "- apply update from sdcard"

Press the "N" physical button to selected the highlighted option

Press the volume down button so you highlight the "- Yes - Install /sdcard/update.zip"

Press the "N" physical button to selected the highlighted option

If you select 'install zip from SD', then pick the stock 1.1.zip file, it will work.

Would the original poster please go back and fix the instructions? Thanks!
[Nook Color Android Development] Stajdanley:
Thanks for this, Brian. I have tried to return to stock using a couple of the files floating around and all of them left me stuck at the black n screen. Your .img had me up and running in ten minutes. Thanks, again!

I want to know of all the modems out there wich one is the best for a rom??
[Vibrant Q&A, Help & Troubleshooting] jaetm83:
look at this thread:

http://xdaforums.com/showpost.php?p=9734167&postcount=1

there is not the best modem yet imho, nothing is perfect, but for froyo (2.2) many found that ka5 modem is the most efficient, reliable and fast so far.. modem performance can vary depending on where you are, how good your signal strengths is, what kinds of interference there may be.. so on. try flashing each one yourself - it's pretty quick - and see which one works best for you
[Vibrant Q&A, Help & Troubleshooting] daworship:
Im asking cause someone told me to flash Nero V5 told me that rom was one of the most stable and great for everything i have tried out i guess every rom, and by far i can say tha Bionix V and Axura are the most impressive and then the Flagship. But im just searching and testing, to see what i like most.
[Vibrant Q&A, Help & Troubleshooting] jaetm83:
sorry i misunderstood and thought you were just looking for all the modems out there- as i edited in my post i think you should really try each one for yourself.. people get various results no matter how new the modem may be.. i got bad results from the initial bionix-v with ka7 modem. no luck with kb1 either. but as soon as i updated to bionix-v v1.2 that comes with ka5 modem, my download/upload speed over 3g and wifi picked up again
[Vibrant Q&A, Help & Troubleshooting] daworship:
Thanks the thing is im from Puerto Rico, and where im at right now i dont have 3g cause the towers arent near, so im judging most of the rom from my wifi signal and of course quality of sound voice, apps, etc etc, with every rom. So that's why im trying to find something that could give my phone the boost to work great
[Vibrant Q&A, Help & Troubleshooting] jaetm83:
off topic but i wanna talk a bit about sound quality.. i just can't wait to see tw implementing the kernel eugene is testing right now. because of the source code eugene came up with he was able to add support for voodoo sound v4 which will significantly boost sound quality of our handsets. i read hundreds of pages of discussions in i9000 forum regarding supercurio's voodoo lagfix/sound projects, and only heard good things about it although i have not yet tried eugene's kernel myself amidst fear for messing up and being lazy. hopefully teamwhiskey will release a new stable version of bionix with eugene's froyo 2.2.1 kernel with voodoo sound.. it's so exciting already!

I recently flashed Gio's OTA Froyo 1.8.1 and once it had finished flashing, it noted to upgrade my kernel version.

I've flashed at least a hundred rom's onto my phone, but I've never updated or flashed a new kernel. I skimmed the forums and I found a couple threads:

SGS Kernel Flasher I would look into this but 1) it seems it won't work for my MT3G and 2) if it would work, I have no idea if it would be safe to use

ezterry's 2708+ enabled kernel I was looking into using this kernel with the updated radio version, seeing that my radio version is 2.22.23.02, but my issue is with the guide he posted. Generally I can figure stuff out, but thats because I have simple step by step instructions to follow. I'm tech savvy, but not a genius when it comes to hacking my phone.

I just want to figure out the easiest way to learn how to get myself a new kernel, be it a youtube tutorial video, a step by step guide from another forum (or one here on xda that I somehow missed, because I looked...)

Any help is much appreciated, even if you tell me "look at this thread you noob"...lol
[myTouch 3G, Magic General] lucky825:
I should also note that the reason I'm not following ezterry's guide is because I have that feeling I would miss something (because I tend to do that) and end up bricking my phone.
[myTouch 3G, Magic General] 2beta:
- Download a kernel (zip file)

- put it on the root of your SD card

- Go in Recovery

- Backup with nandroid

- Flash zip file (your kernel.zip)

- reboot

- if it's not working (boot loop), simply restore your backup or find a other kernel to flask

Always flash kernel after the rom, because lot of rom has a kernel inside, so you need to flash after to have your kernel.

Flashing a kernel is the same as a rom, no more risk!

Edit :

! Kernel is not the same than SPL or Radio !

U probably won't get a spot-on answer to your question cuz we all sorta stay in different locations...Tk me 4 instance, i'm in Malaysia so hw would i be sure my ROM which works perfectly here (network-wise) will function d same way in ur location & with ur carrier?..i think not...So just go out there & try several ROMs till u find one which gives u d satisfaction u seek...There are no shortcuts..

P.S. Make sure u follow each build's Dev's instructions to d letter...

network issue?

well this was more a question for a developer that might have such knowledge from experimenting in rom development but as a user your self sir ...if you've used multiple roms on your phone then maybe even you might have noticed a difference in signal from one rom to the next
[HD2 Android Q&A, Help & Troubleshooting and Genera] voncrane:
Yes i'm ur average user who has tried multiple ROMs...From WinMo "solo" and dual-booting with android...to full android now...i can't count d number of flashes i've done, so yes i've noticed signal differences (some major, some minor)...Hweva dis issues were not mirrored by d majority of users from d states despite using d "exact" same ROM...Go figure..

[G2 and Desire Z Q&A, Help & Troubleshooting] samuraifez:
Ok guys, I've tried to figure this out using other threads on the forum, but I've still come up with nothing!

I'm running cyanogen mod with clockwork recovery AFAIK. Bought the G2 on eBay already rooted, and everything has been working great until yesterday. All of a sudden the phone gives me the infamous "SD card blank or has unsupported filesystem." Argh! I've tried reformatting the card through the OS, and then it tells me to insert a new SD card. Ok, I reboot... annnnnd the same thing again. Next I tried mounting it through the OS. After it's done it tells me the card can't be mounted because it's probably corrupted. Let me just say I don't think that's the case because I was using it RIGHT before this started happening. When I try to connect through Windows and format it doesn't recognize any storage in the device.

So now I'm here. What the heck do I do, xda?! Is there something in the recovery menu I should use? Any suggestion is greatly appreciated, and if you need any more info please ask!

Alright, now it's getting really bad. I attempted to format that card in the computer, but it actually did seem to be ****ed up, in that the computer saw the card once and then it was invisible. Ok, so I order a new 8GB microSD card, arrived today. I format the card using the above program, succesfully, throw it in the phone, and bam, SAME ****ING PROBLEM. What the ****? This is ****ing BULL****.

Now I'm considering re-flashing the phone, but that's a last resort option. Is there something that needs to be on the SD card for cyanogen/CWR for it to even work? I didn't think this was the case, but if it is, WHAT do I need to put on it?

Again, this is quite infuriating, so any help or direction is greatly appreciated.
[G2 and Desire Z Q&A, Help & Troubleshooting] EdKeys:
This is what I would do. I would format the card on the computer to fat32 format. On the phone I would boot into recovery and select wipe data/factory reset, then still in recovery I would go to advanced and wipe dalvik cache, and then still in recovery I would go to mounts and storage and format system and format boot. Back on the computer I would re-download the ROM (what you have now may be corrupt) and place the zip on the newly formatted card. Then I would put the sd card in the phone and flash the ROM.
