Help with flashing anything to my nook - Nook Color Q&A, Help & Troubleshooting

I have tried to flash my nook several times. First with deeperblues honeycomb and then with cm7. On the honeycomb flash it just hangs on the android_ screen and with the CM7 it hangs on the cyanogen splash screen.
Have tried with different versions of CWR and different SD cards. have tried formatting boot and without for the Honeycomb. Always formatting cache, data and system for both cm7 and honeycomb.
Each time, i flash back to 1.0.1 stock, then root, then try to flash the mod again.
It always works returning to the stock 1.0.1 using the cwr complete restore found on the nook color portal. And the autonooter always works as well.
This is frustrating me as im not amble to install any cool mod on the nook. Does anyone have any ideas as to why my NC is resisting any change i make to it other than root stock 1.0.1?

It sounds like a symptom of not wiping data, but you said you're doing that...
Just to be clear, before flashing, you're doing "wipe data/factory reset", then "wipe cache", then "wipe dalvik cache"? Formatting /system shouldn't be necessary but I guess it wouldn't hurt.

I have tried the wife data/factory reset option once when trying to flash honey comb. Still gave me the same issue. All of the how to's i read had me formatting the data, cache and system, and depending on the how to sometimes the boot partition as well. Have been following those to the letters. This is the first time i have heard of wiping the dalvik cache, is that different than wiping cache under the mounts and storage?

Was there a color sticker on the box of your Nook?
Also, have you tried doing an SD only install rather than flashing the internal?

Not sure about the color sticker on the box when i bought it. It was right after it came out so going on a year ago. I have tried the SD only install, that works with honeycomb at least, thats the only one i have tried, all be it laggy because i only have a class 2 card at best.

I did some searching and i think what your eluding to is maybe my partition is the new style(although like i said i bought it within about a week or two of it originally being released)? would running the repartition in CWR make a difference do you think?

The option to wipe dalvik cache is under "advanced" in CWR. Try that in conjunction with a data and cache wipe.
As for the partitions, I don't think it should make a difference. It also sounds like you're on the old partitioning scheme which is the better one to have. You could try flashing the repartition/reformat zips just for the hell of it. Personally I went with the custom 2/4 setup.

Will try once with wiping the delvik cache, data, and cache. I wont wipe the system or the boot. If that doesnt work, il try the repartition and start from scratch. If anyone can think of anything else please let me know.

Complete Wipe How

Just also help me to understand about wipe.. once you are on wipe menu you get 4 to 5 option. How do I do complete wipe. Should the first option to be selected only or all options to be selected one by one. By now I have been selecting only the first option. Is it safe to wipe the SD card with this.
Wipe factory/data settings. Wipe dalvik-cache. You've now completely wiped your handset.
what exactly is in the dalvik-cache? are there times you wouldn't want to wipe the dalvik?

my understanding is that it is used by the java virtual machine for temp data by running programs... not sure if this is correct.
in any event, there doesn't seem to be a reason not to wipe it - and i've seen many posts about a performance gain if you phone starts to get laggy by clearing it.

Clockwork clears dalvik-cache just fine

There has been some confusion over whether ClockworkMod Recovery actually wipes the dalvik-cache correctly. I decided to test it myself. I booted into CW recovery, fired up ADB, and mounted /data. Looking inside /data/dalvik-cache I saw a list of .dex files (the cache, of course). So I unmounted, then used the CW menu to wipe the dalvik-cache. Note, this is NOT just the "wipe cache" option on the main menu. This is a separate option under "advanced." Then I re-mounted /data and looked again . . . and the dalvik-cache directory was completely gone. Rebooting into Android and looking again, it was back (rebuilt) after a long-ish boot time (rebuilding phase), so I'm sure that at least my install of CW v2.5.0.1 is wiping the dalvik-cache just fine.
If you're still not sure, you could use ADB to wipe the cache yourself:
Code:
adb shell
mount /data
rm -rf /data/dalvik-cache/*
Then you can use the Clockwork menu to wipe everything else and flash your ROM. These three commands actually just delete everything inside the dalvik-cache directory, whereas Clockwork appears to remove the directory entirely. Doesn't really matter either way, the system will replace the directory if it gets deleted.
Feel free to replicate my results. That's how science works.
UPDATE: Just did a similar test with the "wipe data/factory reset" menu option. This actually wipes the entire /data directory, which includes the dalvik-cache, so doing a dalvik wipe would be redundant if you're doing a full data wipe anyway. Correct me if I'm wrong.
Thanks I've never had any problems with clockwork, but it seems like there has been a pox on its name since my arrival to the android/evo community.
In particular, I always wondering if I was just being overly redundant going into the advanced menu and wiping dalvik cache ON TOP of a data/cache wipe when flashing a new rom. I'm gonna trust your experiment and stop doing it!

Can't argue with empty directories. The only possible catch would be if there is a dalvik-cache log or something elsewhere outside of /data, but I'm 99.7% sure just doing a "data wipe / factory reset" will wipe dalvik no problem. Still do the other "wipe cache" option as well, though.
Oh I will..I'm just lazy and if I don't have to go ALL the way into the advanced menu too wipe my dalvik I will feel a whole lot better about the world

redundancy never hurt anybody
when you clear the dalvik are you supposed to get some sort of confirmation. whenever i clear it ask me i want to and when i reply yes, it just goes back to the menu. idk if anything actually is happening. (is this what you guys are referring to?)
Yes, that's what we're talking about. Mine is the same way, but it appears to be fine. For one thing, if you do a data wipe first, the dalvik cache goes with it so there would be no real delay even if you then tried to clear it separately. It's already gone. But there should be some sort of confirmation added to the next update, IMO.

I always wipe at least twice, it's cleaner. No one likes leaving any bits behind after wiping only once.

How to PROPERLY Flash a ROM

Since I have seen alot of individuals within ROM threads stating things such as, "Your ROM bricked my phone." or "I can't get your new ROM to install." decided to make this guide. Hopefully it will solve this issue and help educate people.
What not flasing correctly can do:
1. Cause your phone not to boot
2. Cause Force closes and issues
3. POSSIBLY Brick your phone (though I have not seen an Eris Brick yet)
We must also remember that:
1. The devs of these ROMs are NOT responsible for any damage to your phone
2. The devs spend alot of time with testing to make sure the ROM works.
3. A ROM will NOT always flash over a previous ROM
OK.. So onto the main topic..
assuming you are rooted and using AMON's Recovery. I suggest AMON's because Clockwork has had recent issues. Big thanks to AMON for this!
How to install a ROM properly:
1. Boot into recovery ( with either reboot to recovery option or powerdown and then holding volume up and power )
2. Goto Backup/Restore and do a NAND Back-Up
3. Do a data/factory wipe ( NOTE: if the dev says you can flash over an old version you dont NEED to do this, but if you don't do this and the ROM is not booting then I suggest you restart this process [minus the back-up] and do a data/factory wipe)
4. Do a Dalvik Wipe... 3 times (ALWAYS ALWAYS ALWAYS do this)
5. Flash ROM
6. Reboot and Wait ( after a Dalvik wipe and flashing ROMs first boot can take 3+ minutes to load... BE PATIENT )
More to Come...
If you could, please explain what a Dalvik flash does. Thanks in adavnce, and thanks for this thread. I've never had any issues flashing, but it's nice to see someone explain the basics....

"Dalvik cache is a program cache area for the program Dalvik. Dalvik is a java based virtual machine that is the bases for running your programs (the ones that have the .apk extension). In order to make access times faster (because there's not JIT (just in time) compiler installed by default), the Dalvik-cache is the result of Dalvik doing a optimization of the running program." - Taken From Android forums
Basically it analyzes the phone before it boots. Then it sees what apps you have and will use and assigns cache to them. This way they will load quickly and properly.
When you flash a new ROM apps can change, or if you do a data/factory reset those apps are gone. SO wiping the Dalvik allows it to rebuild itself for what YOU are using.
This is also good to do after cleaning out or removing many unused apps from the phone. I usually do it once a week AT LEAST.
With the exception of a 2.1 ROM running apps2sd on an ext partition, is there really any point to wipe Dalvik if you have just done a wipe data/factory reset (which also wipes Dalvik cache)? And what exactly is the point of wiping Dalvik three times - why is once not enough? Is there something wrong with Amon Recovery which prevents a full Dalvik wipe unless you do it more than once?
It certainly doesn't hurt to wipe Dalvik after a wipe data/factory reset, but it should be already wiped.
I'm still fairly new, but I've flashed quite a bit. I didn't know to wipe dalvik x3. that's an interesting bit of info. Any reason why? Thanks

I believe the reason is that sometimes even after a wipe people have reported residual data in the cache, I personally don't do it three times but I do a wipe, dalvik, dalvik, wipe.
Its not going to hurt anything and it gives me piece of mind.

cool. Thanks for the good info.
x3? I do once before and once after. Frankly once before has been enough for me... though I suppose being safe has never hurt.
If the dalvik cache still won't clear after 3 times you can piss on your phone. That seems to really help.
in most cases once is enough but like I said, it's not likely to hurt anything to give it a couple of wipes to make sure all the junk data is cleared.
Let me put it this way...
I wont use a public toilet just by seeing it is clean... ill clean it like twice ...
This is why I dalvik 3 times lol

It would be interesting for someone like Amon to comment on the need to wipe data or recovery more than one time. In my opinion, once is enough. I'm 100% confident than wipes #2, #3, and so on are wiping blank space...

I personally and others have experienced residual data... so is three too much... maybe... but its safe... two might be a better choice... this guide was made to make sure you have no issues... therefore I said three times for safety... if you want to just do it once... be my guest

At the risk sounding like an idiot, I must ask this:
You mention wiping the Dalvik once a week. When you do this wipe, do you replace it (flash) something over it? Or can you simply wipe then reboot.

Yep, just wipe and boot. After wiping dalvik, it will redo your app tree or configuration if you will, just clears all the current info and rebuilds it fresh.
Great thread, people still need it I guess

[Q] Phiremod to Nightly

I recently bought a used Nook Color online and it came with Phiremod 6.3 installed. The main concern for me is the audio. I use a pair of sensitive IEMs and the hiss from the headphone jack is crazy loud.
I read that Nook Tweaks could solve this problem, but it turns out that Nook Tweaks doesn't support my version. This leads to my current question.
How would I go from Phiremod to the CM7 nightly builds? I have read from a thread that I must start from scratch, but I do not know where to begin. I have never rooted an Android product before. In fact, the Nook Color is my first Android product. I have knowledge of jailbreaking iOS products, but that's about it.
Do I simply follow this guide? Link
I am backing up my apps with TitaniumBackup at the moment. What else would I need to back up to be safe?
TL;DR
1. Do I follow thisguide to go from Phiremod to CM7 Nightly?
2. What programs besides TitaniumBackup should I use to back up my current data on my Nook?
Daily bump. If no replies, I'll just try it out for myself
You didn't mention if you were running phiremod on Emmc, or your SD card. If it is on emmc then just download cm7, and go into recovery . Wipe data, cache, and dalvic cache. Flash cm7, flash Google apps, flash kernel if you want, and reboot. Hope that helps.

Sadly, its too late now, but i will mention that had you had any programs/data you wanted on there, the "Wipe Data" step is fully unneeded, and only results you wasting time re-installing everything. Phiremod IS CM7, with some different skinning. Flashing over Phire is the same as flashing any nightly; wipe cache, wipe dalvik, flash, good to go.

It didn't take me too long to reinstall everything. I just restored it through TitaniumBackup which took about 5 minutes. My Nook was still fairly new so I didn't have much on it. Thanks for that bit of information though

Factory data reset in CM7??

I have CM7 on the sd card. If I choose "factory data reset", will it just remove anything I have added, or will it wipe out any of CM7? I hope this doesn't sound like a dumb question.

I don't know why you want to do that but just pull the card first.....
I don't want to remove CM7 but I want to remove my data and especially my gmail account, which from all other posts and what I can find online, and everything I have tried so far, is pretty much locked in.
I'm never aware of the "factory reset" of CM7.
Does it have one?
Factory reset is for the stock ROM from B&N, nothing to do with CM7 since it's a custom ROM that you're running.
Moreover, you're booting it off the external uSD card.
That's what I'm trying to find out. I'm afraid the "factory reset" would wipe out CM7. And I have seen suggestions to reflash the rom, but it was a very big deal for me to do it the first time, and I would rather not start over.
Hold off a bit.
The "factory reset" you said, might be the other name of "wipe data" in CwM.
If yes, it won't hurt your OS (ROM) but it will wipe all your data info on the device.
Ok, now I am quite confused after reading your other threads. Maybe you should just stick to one.
If you want to wipe the data on the stock ROM, just pull the card and do a factory reset. If you want to wipe it on the CM7 card boot into CWR on the card and wipe the data. Reflashing the ROM will not wipe it anyway unless you also wipe the data so it would not help anyway.

You're right, I should have stuck to just one, but got a little desperate, and thought I had more than one issue. Everything had worked perfectly until I started removing data and clearing caches, and trouble started.
I assume CWR is the "recovery" option on reboot? I did select that, but nothing appeared to happen, went black and then I had to restart it.
Thanks very much though. You have told me exactly what I wanted to know. Reflashing does not remove data, and booting into CWR does. There was also the option of going into settings and restoring to factory default. What would have happened to CM7 if I had done that?

Probably nothing because that resets the internal flash memory to stock and you have CM7 sitting on a card. Definitely nothing if you pull the card first.

Booting into CwM R does NOT remove your data.
It waits for you command to wipe it and you do if you intend to, otherwise, nothing happens.

Thanks for clarifying. So is booting into "CwM R" the "recovery" option on the reboot menu?
