Problems installing custom ROM

Thank you for posting the guide!

I have followed through the guide several times. I'm able to dual-boot and boot successfully into the rooted stock 1.2 ROM with out any issues holding down the "N"ook button.

However, I have tried installing CM7 7.02 zip image several time through CWM and after every attempt to install it hangs as the "N Color" Nookdevs boot screen. I never see the cyanogen7 boot screen.

I can boot this image on SD and all works fine.

Any suggestions on what I am doing wrong?

Update:

I flashed my NC back to complete stock and tried the steps again - with the same result. I then tried indagroove's guide and finally success. This late at night I don't have the time - sleep beckons - to compare the two methods in more detail.

[Nook Color Android Development] rajendra82:
Thanks for your guide. With its help I was able to get my Wife's nook to dual boou Phiremod 6.2 as primary, and Stock unrooted 1.2 as secondary. She was very skeptical with me saying it would work better than rooted 1.1 setup (which I had to keep off WiFi for the past week to keep it from updating). I went to dual boot because of a lack of 1.2 autonooter equivalent that works without issues so far, and I am now convinced that this is the better setup anyway. After she saw the dual boot, she exclaimed "this is cool", which is great, because otherwise I would have been sleeping on the couch until she could explore the B&N app store for herself.

The only questions I now have left are the backup and restore capabilities of CWM 3.0.2.8. When you launch into internal CWM recovery, and do a backup, do both the primary and secondary boot setups get backed up? When restoring, does it restore only the primary boot partitions, or does it restore secondary as well?
[Nook Color Android Development] jm20:
rajendra82, I think CWM just backs up the Phiremod part of the partition when you do a backup. I backed mine up and I think that is all that is in the backup file. From what I understand you can flash a new ROM and it will replace the Phiremod but leave the stock ROM alone as long as you don't overwrite the boot file. I haven't tried it yet because I finally got this thing the way I want it and don't have time to mess with it for a few weeks. If anyone has more information about this I'd also like to know if there is a way to back up each partition separately.
[Nook Color Android Development] rajendra82:
After studying the internals, I agree with this assessment. CWM only backs the original partitions up to mmcblk0p8, and does not look at mmcblk0p9 or mmcblkp10, where the secondary /system and /data files live. Since I hardly do anything significant on the B&N stock side, it would be a piece of cake to get everything back the way it is in the rare event if the system had to be rebuilt from nothing, by following the guide steps again, but when it says to install ROM via CWM, restoring the backup instead. On the B&N side, I'll just have to download any purchased books and apps, but that takes just a few minutes anyway.

The part of the scripting, that set up this dual boot, that I am now trying to figure out, is the commands where the stock ramdisk was unpacked, edited, and repacked as a new file, so that it now works in a dual boot situation. I can understand some of the sed commands to replace partiton names of mmcblk0p5 and mmcblk0p6 with mmcblk0p9 and mmcblkp10, as that's where the /boot and /data were cloned to, but there are a couple of other sed lines that are playing around with syntax for /cache. Can anyone in the know explain what those are trying to do, and why? That way if B&N comes up with an update to 1.2 with a new uRamdisk, I can edit it before applying it to my dual boot setup, and keep everything on the phiremod side untouched.

After installing CM7

I have found that every time you change the rom version (ie. 2.1, 2.2, or 2.3) on the primary partition you must perform a factory reset in CWM as the last step of the procedure or you will get stuck during the initial boot. The reset does not effect the secondary boot OS. This might help those getting hung up while setting up dual boot on the Nook.
[Nook Color Android Development] Kayak83:
Now if we can just have a dual-boot thread dedicated to all of the current ROM's, packaged specifically for dual boot Emmc and SD.
[Nook Color Android Development] METDeath:
So if I wanted to revert back to complete stock, how would I go about doing that?

I've looked at some of the stuff in the old dual boot threads, but they don't quite seem to apply.

[Nook Color Android Development] notinterested:
Followed instructions to a T in the end stock wont boot just stuck on the big N.

Figured it out, prep dualboot needs to be done on CWR from internal because of a permission issue when doing it from SD. Every other step can be done from CWR on the SD.
[Nook Color Android Development] :
I am getting the same error. I can't seem to get past flashing that prep-dualboot-0.1.zip. Any ideas?

Edit... never mind, I fixed it myself.

[Nook Color Android Development] jdellingson7:
Just a few questions. I just flashed this and was wondering #1 if it was safe to flash a oc kernel? And #2 what method do i use to undo the dual boot if needed?
[Nook Color Android Development] TDO:
Why are you doing it the hard way?

Here you find an image with dualboot.

And the best - it leaves your internal installation completely untouched!

If you want to flash also a modified Image to your internal memory just replace the modifed CWM with a stock one and you are ready.

[Nook Color Android Development] saber0091:
THIS.

This saved my sanity.

For some reason my NC just refused to boot after loading the custom ROM, following the directions in the OP's post. ...which aren't very different from indagroove's directions, so what gives?

Edit: just tried booting to rooted stock, unit loads CM7 no matter what I do. Fail again.
[Nook Color Android Development] saber0091:
Not safe.

Believe it was in the Original Post.

Dalingrin might have released an update to the OC kernel though, so be sure to check with him! :)

[Nook Color Android Development] Eddog4DROID:
I have got this to mostly work with 7.03 stable, but, I keep getting media process force closes. I know that has to do with the file system. I think? Any ideas on this?

Have newest CWM and 1.2 partition unrooted is working great...

I'd prefer to use nightly 87 but that seems to overwrite the second partition.

EDIT: Clearing Data Cache on "Media Storage" seemed to fix it in the stable version. Anyone know if you can dual boot the newest nightlies with this?
[Nook Color Android Development] tubmanx:
I CANNOT get past this step! I get this same error every time. It's driving me nuts. Little help anyone? I'm using CWM v3.2.0.1. I have a feeling it has to do with the /media partition but I'm not sure how to fix that.
[Nook Color Android Development] slugbug2010:
Am I reading correctly that I need to get back to rooted stock NC in order for this work? I am currently running emmc CM7 102 nightly and really want to be able to boot to rooted stock.

I am VERY happy with my set up and will make a solid back up of course. I prefer the actual stock B&N reader to the app and want to to use that for reading.
[Nook Color Android Development] whoojong:
Is there any way to deregister the stock nook partition after you used this method to dual boot? Thanks!
[Nook Color Android Development] zavien3:
Boot menu?

Here's my problem and I didn't see anyone else with a similar problem on here. I'm using stock 1.2 and a CM7 nightly with a Dalingrin OC Kernel. Dual boot worked until I flashed the nightly. Now holding the N button takes me to a dual boot menu instead of just loading up the stock 1.2. Changing the boot device and boot mode to ALT and selecting "boot now" it says "booting: one moment.." and just hangs. Where in the world did this boot menu come from?
[Nook Color Android Development] zavien3:
..Answered my own question. Sorry. Nightlies with Nook Tweaks installed covers it. Buttons change on boot. Holding N goes to boot menu, holding Volume up/down boots alternate.
[Nook Color Android Development] oakleyrdc:
How do I go back to single boot if I need to. Just wipe everything, or are there commands I have to enter?
[Nook Color Android Development] godgib:
So when you flash new stuff how is CWM determining what partition to install to? I'm assuming there's still only one CWM installed, if not how would you access it?.
[Nook Color Android Development] AidenM:
CWM always install to the main partition unless the package says differently.
[Nook Color Android Development] loganthered:
I have a weird problem. If I'm using the u-boot version .3 or .4 I can only boot into stock. Not pressing a button just had the device sit there, but I can hold the n button and get into stock. If I use the multi-u boot by j4mmer or that comes with cm7 I can boot

Cyanogen but selecting the alt boot never loads and it will sit there asking me to wait while it loads. Any ideas?
[Nook Color Android Development] jasoraso:
Your problem is that the cm7 alternate boot is looking for the dual boot to be named uAltImg, vlvut the dual boot file you used named it uEimg.

This file will copy the 1st boot files to the correct name.

http://db.tt/SvVAQrx

You will need to go back to having primary boot be barnes and noble softwarez then flash this file to copy the bn software to the dual boot partition, and it will create the dualboot files that cm7 is looking for.

EDIT:

Or, if you have the dual boot already set up, you just need to rename the files:

FYI on how I renamed the files:

using ADB (via adb wireless) from cm7:

adb shell

#mkdir /data/tmp

#mkdir /data/tmp/boot

#mount /dev/block/mmcblk0p1 /data/tmp/boot

#cd /data/tmp/boot

#ls

(at this point I noted my files were uFImg and UFRam because of the modified uboot.bin I had been using to load 1.2 froyo instead of 1.1 Eclair - thus the switching of F instead of E).

#cp uEImg uAltImg (adjust this as neccessary from E to F w/ any necessary extension)

#cp uERam uAltRam (adjust this as neccessary from E to F w/ any neccessary extension)

#cd /

#umount /data/tmp/boot

#rmdir /data/tmp/boot

#rmdir /data/tmp

#exit

adb reboot
[Nook Color Android Development] loganthered:
Actually I already renamed the files. Used the naming convention the boot manager specified. Still no love.
[Nook Color Android Development] TJNooker:
Thank you! That worked just like you said it would.

I tried to get my phone unlocked today, however ever since then my phone hasn't been able to connect to any networks. I had to give my Imei number to get in unlocked, is there some way this could have been used to block my phone?
[Hero, G2 Touch Q&A, Help & Troubleshooting] pulser_g2:
Yes in theory it could. Try the old sim and see if it works.

To block an imei requires access to the network systems, although you could phone them up and perhaps maliciously block an imei.

Did you use a reputable unlocker?
[Hero, G2 Touch Q&A, Help & Troubleshooting] johno86_4:
I used one off ebay however they had 15000 positive feedback.

I rang T-mobile and they say my phone is not blacklisted but its also not been unlocked. I dont know if this is true as when I put my unlock code in it said unlock ok and now when I put another network sim in it doesnt ask for the code. Ive since tried to use an orange sim card in it and this works but I dont know if this is anything to do with the fact that Orange and T-mobile have merged. :confused:

If it isnt unlocked then i dont know where to put a new unlock code in. :confused:
[Hero, G2 Touch Q&A, Help & Troubleshooting] pulser_g2:
Lol you are fine.

Tmobile don't know it is unlocked. It worked fine if the sim doesn't ask for the code now.

If an orange sim works then phone is OK. What is original problem again?
[Hero, G2 Touch Q&A, Help & Troubleshooting] johno86_4:
Lol sorry I havent been very clear.

Ive bought a Tesco mobile sim and that is what I want to use however when I try this sim it wont connect to the network. Ive also tried a O2 sim with the same result however an Orange sim does work :confused:

I really have no idea what could be causing it and ringing Tesco/T-mobile has been no help at all lol.
[Hero, G2 Touch Q&A, Help & Troubleshooting] snailydale:
Might be a stupid question but are you sure you can get Tesco Mobile signal? Both Tesco Mobile and o2 use the o2 network. So that's probably worth checking.
[Hero, G2 Touch Q&A, Help & Troubleshooting] johno86_4:
Ive tried it in my girlfriends iphone and it works perfectly so I cant imagine its the signal. I'm totally flummoxed, the only thing I can think of is if the phone isnt unlocked, but then why then does the orange sim card work? :confused:
[Hero, G2 Touch Q&A, Help & Troubleshooting] johno86_4:
OK I've come to the conclusion that it hasn't been unlocked and the reason the Orange sim card works is something to do with their networks being joined. If this is the case is there a way of re-entering the sim unlock code?
[Hero, G2 Touch Q&A, Help & Troubleshooting] imadiamond:
TMOBILE has blocked your sim, you may need to root

TMOBILE has blocked your sim, you may need to root. My experience is this: I have a rooted HTC that works fine, however when I put the sim in my S2 or a second T-Mobile phone I get the error message "cannot connect to network" even though I have 5 bars.

I will not take any credit for the link below, but i wanted to share this with everyone.....It is by far the easiest rooting for the HTC Inspire....

You follow instructions, and all will be well.

only have to have the following before hand:

1) HTC drivers for your phone installed on the computer (get that by installing HTC Sync.....then you uninstall the HTC sync program w/o removing the drivers)...you can't have HTC Sync when you are doing this on your computer.

2) get the latest .net framework.

Here is the problems i have had which i have fixed thanks to some snazzy guys in here that helped me:

1) GPS was not working for me, but i installed the ginger bread Radio in the place of AT&T's radio....then all worked fine.

Take the SIM card out of the Thunderbolt and put it into the MIFI/Samsung Hotspot device, and see if you still get LTE connection from the MIFI/Samsung device? I would like to buy one of those things but only if I can get unlimited data with it.
[Thunderbolt General] mcmillanje:
Wont work. Lte =/= GSM. It uses dual authentication using your unique imei (device id). Also: it will recognize the device_type as an aircard.
[Thunderbolt General] Topher227:
mcmillian is correct as you can not use the $30 unlimited data in an aircard, Verizon would see the device ID and turn off your data... however to add a couple additional pennies on the topic...

you can use your LTE sim card in ANY LTE device. I've tried it with other Thunderbolt (hmm, my phone replacement, ugh) and it worked flawlessly. I really do miss that about GSM carriers as i would take the card out of my nice phone, and put it in a crappy prepaid phone when i went to the beach, or Six Flags. If it fell out or got lost.... oh well!
[Thunderbolt General] mattgattis:
Hmm if it worked in other thunderbolts I think it's definitely worth a shot in the aircard. I'm less concerned about Verizon seeing it and shutting it down at some later point... I know how big companies work and it would likely go unchecked for years before they decide to care enough.

It doesn't go unchecked for years, it registers the MiFi to that line the second you put the SIM in and puts a compatible data feature on the line automatically. So you won't magically get unlimited data they will just convert the plan automatically.
