[Nook Color Android Development] atrociousNK:
help cant get into recovery mode

For some reason I can't figure out for the life of me how to get my NK into RECOVERY MODE.

I am following the following directions found on the first page:

I have tried other suggested Power & N button combinations to no avail. What can I do?

I'm trying to get into recovery mode so that I can get Dalingrin's OC Kernel for SD Card to install on my NK. HELP!!!!

Any suggestions are truly appreciated, total NOOB on here.
[Nook Color Android Development] zombieflanders:
Are you running nightly build 88 or higher for CM7 and version 1.21 or 1.3 of verygreen's installer? If so, just boot into normal CM7, press the power button until the menu comes up, select restart, and when it gives you the option, choose "Recovery".
[Nook Color Android Development] atrociousNK:
I'm actually running CM7 stable version, version update-cm-7.0.3-encore-signed.

I decided to run stable version since it was the first time running CM7 of my SD card, so unfortunately selecting Reboot to Recovery doesn't work on my version. :(

I also tried selecting reboot into recovery from ROM Manager and didn't get me into recovery mode either.
[Nook Color Android Development] verygreen:
If you installed using version 1.3 of the installer, you should have used version 1.2.1 instead as per the warning in the instructions. Now you need to replace the u-boot file on your boot partition with uboot.bin from update.zip
[Nook Color Android Development] atrociousNK:
I'm not understanding what I need to do, can you provide with verbose guide. I'm complete noob and my knowledge and familiarity with system is slim. will this solve the boot issues I'm having?
[Nook Color Android Development] verygreen:
If you mean boot into recovery, that would be solved.

Get the update-genimage-1.3.zip file referenced in the "upgrade" section of the first post, unpack it, extract "u-boot.bin" file.

Mount first partition of your sdcard (labeled boot) on your PC, copy the u-boot.bin file you got from the zip file onto the sdcard instead of the file that is already there.

unmount the sdcard and plug it back into the nook.

Turn on the nook and you are ready to go.
[Nook Color Android Development] Bonnie_Raitt:
I want to make my NC run 7.0.3 stable from the SD card. I understand I need the generic-sdcard-v1.2.1.img file instead of the 1.3 version. However, I am having trouble finding it. Can someone point me to a link or point out the error in my reasoning? Thanks
[Nook Color Android Development] verygreen:
in the download url replace 1.3 with 1.2.1.

the result is something like this.

after you re done installing CM7, upgrade to installer 1.3 with the upgrade.zip, the initial old-CM7 unfriendly u-boot is only contained in the original image, not in the update.
[Nook Color Android Development] lschroeder:
I would love to use phiremod-nook-v7-TEST.zip with v1.3 Size-agnostic installer. Any simple way since I am currently running nightly 99 on SDcard. Its name is phiremod-nook-v7-TEST.zip. There is also phiremod-nook-gapps.zip to install plus a launcher pro backup.

Pretty sure we need changes to [CWM][CM7][HC][NOOKCOMB][PHIREMOD]CWM for Flashing Roms to SDcard + More! [5/31]. I made a similiar post there.

Edit: over at post below the orginator of the thread posted that he will be coming up a fix tonight. He also thought that maybe we can just rename using our OP specification and install it here.

Edit1: is there a way to make boot partition larger as my update-phiremod-nook-v7-TEST.zip is around 22 MB too large. I have tried EASEUS window 7 partition program. It only let me shrink the 4th partition but not add the needed MB to the boot partition.

http://xdaforums.com/showpost.php?p=14744990&postcount=265

Since this is 7.1 instead of 7.0 this technigue earlier in this thread would also be invalid?

[Nook Color Android Development] atrociousNK:
Problem solved, could finally get into recovery mode.

I just went back and performed clean install using the nightly build 102 and was able to get into recovery mode with no problems.

The stable build was not working for me. I was able to now install gapps and Dalingrin's OC Kernel on my NK.

MISSION ACCOMPLISHED. THANKS FOR ALL THE TIPS!!
[Nook Color Android Development] chumpster:
I have kind of a noob question. I am running the following:

- generic-sdcard-v1.2.1.img

- cm-7.1.0-RC0-encore-KANG

- kernel version 2.6.32 (051311)

I would like up to upgrade to one of the new nightly build (post -87) and the new kernel. So my question is what order should I do my update? My assumption is that the kernel update should be last, but I am not sure if I should update the installer first (from 1.2.1 to 1.3) or CM7.

Any advice would be appreciated.
[Nook Color Android Development] verygreen:
Yes, installer, CM7 then kernel.

You probably can combine installer and CM7 into one step (make sure you have at least 1M free space left after you drop 2 zips to the first partition).
[Nook Color Android Development] chumpster:
Thanks for the reply. But if I install CM7 first, won't I run into the same problem that atrociousNK ran into where I would need to update the u-boot file on boot partition?
[Nook Color Android Development] verygreen:
Well, I am not telling you to install CM7-n87 first, I am telling you to update the installer update first, then CM7.

The -87 and later images include their own u-boot already and it would override the installer's u-boot after that so you will have zero problems.

(besides the u-boot in installer's 1.3 update zip is the same as in 1.2.1, it's only

the u-boot in the sdcard image that is different to avoid the issue of some people having screwed up bcb and not able to install as a result).

If you do the double update of installer update + CM7 update - just copy the installer update first, I believe the processing is in readdir order which for fat is just the order in which you copy stuff to the fs.
[Nook Color Android Development] chumpster:
Thanks. I give it a try. I really do appreciate your work. Just to let you know, one of the reason for me to update is to try out the USB host function.
[Nook Color Android Development] androidmonkey:
I followed the instructions but when I put the SD card in my NC and turn it on, it boots right into the standard home screen.

Does the NC have to be rooted for this to work?
[Nook Color Android Development] AReynante:
Does installing a new nightly wipe anything?
[Nook Color Android Development] chumpster:
No the NC does not have to be rooted for this this work. If you follow OP's instructions, it should just boot of the SD card without any problems. I think there was a thread here about a month ago where a defective NC would not boot off the SD card, other than that, I think it should work.
[Nook Color Android Development] chumpster:
According to OP instructions, all of the user data and apps are not touched. I just did my first update and I can confirm all my apps and data are still there.

If you are concern, you can make an image of your sd card before you update to the new nightly (this way you can always revert back).

I am writing this assuming you will be following OP's instructions on updating the CM version and not wiping out your sd card with a new image.
[Nook Color Android Development] androidmonkey:
Thanks for the reply. Crap, I cant get this to work. Im using a Class 4 Sandisk 16GB mSD card. I also reformatted the card and redid the image. I dont get it. If its a bad SD slot, then I wouldnt see the card and contents.

What should happen during the bootup process? First thing I see is a screen that says "Read Forever", then the "N" screen, then the "nook color" screen.

Oh, another thing I dont understand is the installer image is 8MB, then 120MB unzipped. Then when I write the image to my SD card it only takes up about 8MB. Is this normal?
[Nook Color Android Development] AReynante:
So just take the "cm_encore_full-105.zip" put update in front of it, and then it'll flash itself?
[Nook Color Android Development] hoodred:
repair parition 3 with recovery ?

Is there anyways to check/repair the card partition in recovery without flashing it again?

I think my partition 3 went beserk. All apps goes force close and comes with error.

and Cant use ROM MANAGER either since it also gives error.
[Nook Color Android Development] verygreen:
Connect with adb and do rm -rf /cache/*

then reboot.

If you suspect that your partition3 went bad, just plug that card into a linux box and runs e2fsck on it (of course if it went bad, when you connect with adb and do a dmesg, you'll see tons of ext4 errors there)
[Nook Color Android Development] chumpster:
Don't need to change the name. Just put it as is under the 'boot' of the SD card and boot into recovery mode. If you need instructions on how to boot into recovery, see OPs first post.
[Nook Color Android Development] hoodred:
can I just use recovery to recover partition 3 ?
[Nook Color Android Development] hoodred:
well Im trying to help my cousin. and she doesnt has linux or know how to use adb.

Im hoping there is a way to either put a file on partition 1 "boot" or use recovery boot to check or repair partition 3
[Nook Color Android Development] verygreen:
Well, if she has CWM installed on the emmc, you can boot into emmc recovery and erase cache.

If she does not have cwm and the issue is like what I have seen in the past with some early pre-87 nightlies where everything just crashed, I guess flashing a more stable nightly might be a good idea.
[Nook Color Android Development] AReynante:
I had tried without putting "update-" in front and it didn't work, so before giving up and just reflashing it all, I tried adding that on, and it worked perfectly. But thank you though :)
[Nook Color Android Development] acme2ajax:
Hey DizzyDen.....Thanks for your advice....but....sadly...

It doesnt work.....

I pressed n button, then pressed power on and kept holding both buttons 3-4 sec after the touch future reading screen comes....

At this point...if i leave both buttons, the nook never boots.....

If i keep on holding......nook boots into the existing installation....

No sight of any penguin........

Will like to clarify this though....

I have not installed verygreens image from this thread...you know...the one which is 9 mb expanding to 130 mb....

I have installed the sd card BT version he had posted quite some time earlier....it is this installation i try to update......Maybe i am doing something wrong....or may be i am plain unlucky.....

Would like verygreen to create a 2gb bootable version of the latest nightly though....

Thanks for all your help :)
[Nook Color Android Development] DizzyDen:
Acme:

If you downloaded the uRec images and placed on the root of the boot partition... try doing this.....

Turn nook off by holding power until it completely shuts down....

Press and hold N button

Press and hold Power button

about 5 seconds after seeing touch the future screen... release power.. keep holding N button...

See if that helps

Green:

I guess I'll install Ubuntu dual boot on this computer... my Ubuntu computer had crashed...

Perhaps I will be able to assist you further that way.
[Nook Color Android Development] acme2ajax:
Mr. DizzyDen...... You Sir....are simply awesome....

It worked.........

================================================

Press and hold N button

Press and hold Power button

about 5 seconds after seeing touch the future screen... release power.. keep holding N button...

=====================================================

The nightly updated.....the elusive penguin showed its face......(let me tell u...I was never this happy seein a penguin :) )

Thank You very much......

Now....if only u can sort out the 16gb card problem ;)
[Nook Color Android Development] aludal:
Thanks, verygreen. It was just a big bunch of interesting commits today. Will wait till regular 31st nightly shows up. Please do not hesitate to post your 2.6.35 kernel for CM7/HC when it's ready for testing.

DizzyDen:

Thank you, DizzyDen, for your discovery. Will try it with n31. BTW, anyone can list n30 improvements as compared to n27 or earlier?
[Nook Color Android Development] littlejohn07:
I cannot seem to get market to download any apps it just hangs on starting download. I installed gapps along with cm7 all at once when first loading sdcard.

Any suggestions?
[Nook Color Android Development] :
I successfully followed verygreen's instructions and am now running CM7 off my 8 gb sd card on my Nook.

One major issue I'm having is that maybe every 10-20 seconds CM7 on my Nook freezes. If I press the screen at this point, I will get pop up with the option to force close whatever process or to wait. If I click wait, I may have to wait 10-20 seconds before I can continue.

I'm using a class 4 8 gb sd card. I'm wondering if I'm having this problem because some process is trying to write to my sd card and it's causing issues with the scheduler (?)

Any ideas? Any others experiencing this issue?
[Nook Color Android Development] lekofraggle:
Giant Rider,

What application does it want to force quit?

What happens if you select quit?

Do you have logcat installed?

Verrygreen, thanks. This is wonderful.
[Nook Color Android Development] :
It happens with every app. I've been selecting wait. I'll select quit tonight. I'll post logcats.

I am guessing it's not the rom because of the behavior (total guess). I'm guessing it's something to do with read/writing to the sd card while trying to execute whatever process. It happened a lot while I was downloading a few apps from the Market which could be a key.
[Nook Color Android Development] wallyw:
I follow your steps and everythign comes up fine. I am using an 8 gig card and CM7 sees it properly. The problem is, when I take the card out and put it it my windows machine to add the gapps, it asks me if I want to format the card and doesnt see any of the partitions anymore. It just sees a 130mb raw partition. Sadly I don't have a linux box handy.
[Nook Color Android Development] verygreen:
Hm, this is certainly strange and unexpected (though I don't have Windows to really try it).

Anyway an alternative approach you could take is to mount your boot partition somewhere like this (in adb shell):

mount / -o remount,rw

mkdir /boot

mount /dev/mmcblk1p1 /boot

then do adb push of your gapps to /boot

then in adb shell again:

umount /boot

mount / -o remount,ro

then power off and restart in recovery mode.

Or you can export the resulting /boot partition as a shareable space in and mount that in Windows directly, though I cannot quote you the commands necessary for that off the top of my head.
[Nook Color Android Development] wallyw:
Thanks for the quick response. I will try that. I think windows 7 has a problem where if the first partition on an sd card isn't fat32 then it cant see the rest of the card. Anyone else have this working on windows?
[Nook Color Android Development] anonim1:
When I waited 5 seconds, I ended up releasing the power button right after the Touch the Future of Reading message, and it did not go into Recovery mode. This is what worked for me:

1. Hold both the power and the N buttons down.

2. 2 seconds after the Touch the Future message comes up, release the power button (but keep holding the N button).

3. As soon as the Touch the Future message disappears, let go of the N button.
[Nook Color Android Development] 12paq:
@Wallyw. Some internal card readers will not read High Capacity sd cards. I can get my 8gig card to read on some newer machines but not my older ones with older card readers. It will ask me to format it, if it will even see it at all. I have to use a reader that is HiCap for anything 8gig and up.

Hope this helps.
[Nook Color Android Development] wallyw:
Thanks - I wish it was that simple. It had no problem seeing the 8gb card when it was one fat partition. Nor does it have a problem with my 16gb card. It sees the card fine after I burn the first image to it too. Once I boot the nook and it creates the other partitions then when I pull it out windows can no longer see it...
[Nook Color Android Development] anonim1:
I was never able to get this utility working, but maybe you'll have some luck with it.. http://xdaforums.com/showthread.php?t=952456
[Nook Color Android Development] wallyw:
You sir are amazing! Thanks that worked. It let me mount the boot partition and now I'm happily installing gapps.
[Nook Color Android Development] FishDoc:
A truly great gift!!

I'm running this on a SanDisk 16gb class 4 card and I'm amazed----and I don't say that often. This is a great program and a piece of cake to install. My thanks to the author.

[Nook Color Android Development] Lights218:
Awesome job thanks. Simplified thing for me.
[Nook Color Android Development] :
Note: I am new to the NC and figuring things out. I think I'm having the wifi issue. My NC seems to run CM7 great off the sd card provided I turn off wifi and don't try to do anything that requires network connection. The bad part is I am struggling so far to find a fix. It seems there may not be one....?????
[Nook Color Android Development] hoodred:
the emmc is the factory nook color without cwm.

I was the one who gave her the card installed with stable cm 7.0.3 encore.
[Nook Color Android Development] GTT1:
I have a spare SD card which I use every once in a while to see how the latest nightlies are performing.

I simply put the zip files on the partition 1 and reboot.

I keep reading about people clearing cache and Dalvik cache. I don't clear anything but haven't noticed any major problems other than my wifi doesn't work properly on wake up a lot of the time. It will not connect and I have to reboot to get a connection.

Should I be clearing something before doing the update? If so how?

I don't have cwm on emmc or sd have never used it.

Have used file explorer to look on EMMC and on my SD but don't even see any cache/data directories that seem to have anything in them.
[Nook Color Android Development] nook-color:
Is there an alternative place I can get Android Market download.

The wiki-link in the OP - I've tried the past 2 days - and it sets off my Virus software as a Malicious link - that I don't want to download.
[Nook Color Android Development] verygreen:
I don't clear anything myself and with only upgrade I see a cache being rebuilt in logcat anyway.

That said I did have a problem once that manifsted itself in everything forceclosing in one of the pre-85 cm7 snapshot that I was only able to clear by removing cache and rebooting, but that only helped until next reboot, so basically required a cache cleaning every time you boot and it was obviously a problem with cm7 at the time.
[Nook Color Android Development] Aerlock:
This may be a stupid question, but can you build the sd card for this from within android? I currently have my NC rootedand no access to a computer for several days (posting this from my phone) and have ask the files neededbut no way to make the initial sd card other than my phone our nook.

Thanks,

- Aerlock
[Nook Color Android Development] verygreen:
Should be doable as long as you can stop vold from mounting sdcard (just ejecting it should be fine). You need to have rooted device obviously.

Just unzip the image on the nook and then write it to sdcard with dd, target device is /dev/block/mmcblk1 (not no pX part at the end).
[Nook Color Android Development] cirehawk:
A couple quick questions. I am running the 100 nightly. If I update to the latest, will I have to re-install any mods Ive made (i.e. the netflix mod, my honeybread theme, nook tweaks, etc.)?

Also, where should I be looking for information on bluetooth fixes. I paired the NC with my BT headsets, but the audio keeps breaking up. I hear something a few seconds, then nothing, then it comes back. If I move my head, it breaks up. Is this a function of the rom, or are there separate tweaks for BT issues?
[Nook Color Android Development] verygreen:
BT problems sound like a generic range issue. Get real close to the nook ;)

The installation of a newer version should not wipe any of your older changes unless they were to files included with nightlies.
[Nook Color Android Development] cirehawk:
Well I was within 2 or 3 feet as it was (nook on my desk right in front of me). If I have to put my head right next to the nook for it not to break up, then that kinda defeats the purpose of having wireless, don't you think? ;)

Thanks for the info on the upgrade. I assumed that it wouldn't wipe my changes, but wanted to be sure.
[Nook Color Android Development] DizzyDen:
It will overwrite your netflix changes... you will have to edit build.prop again... this is installed on every nightly.
[Nook Color Android Development] Aerlock:
Thanks verygreen! I was hoping it would work but was having a hard time confirming the device for the sd card once I had it un mounted to experiment myself.

- Aerlock
[Nook Color Android Development] :
Flashing to N106 borked my su/superuser.apk.

A fix was suggested that I flash su via recovery. But that method seems to require clockwork recovery mod which isn't supported. Tried to install by renaming update-...zip but that gave me some errors that made me think it didn't complete during recovery and it didn't fix the problem.

Is there any other method you guys can suggest for me to try and fix su/superuser.apk?

Edit...just redid the image and its working again now.
[Nook Color Android Development] DizzyDen:
VG... is the black screen on subsequent updates that is still present due to the multi-boot in CM7 nightlies... or did the issue you discovered before not get into 1.3 ?
[Nook Color Android Development] stolenmoment:
Always reboot into recovery?

When I install a new nightly as in the OP, my NC always boots into recovery, finds nothing to do, and shuts down. I've started replacing the u-boot with one of the menu u-boots (makes it much easier to boot into recovery when I want to) after running the installer. So far, that's easier (for me) than replacing the u-boot in the nightly zip before installation.

Is there some file somewhere that I should delete? That the installer should be deleting? I do see something like "clearing recovery flag" then the output of a very short "dd" at the end of running the installer.

Thanks!

Dennis
[Nook Color Android Development] verygreen:
It did get into 1.3. Works for me, I did 3 or 4 subsequent updates yesterday for some testing and no black screen updates.
[Nook Color Android Development] verygreen:
the recovery request is written into bcb file located on 2nd partition of emmc.

It is cleared after installation is complete so should not have a second bootup there.
[Nook Color Android Development] rhester72:
I saw the 'black screen recovery' as well, but only when rebooting into recovery from the Android power menu...going into recovery from fattire's u-boot always worked properly.

Hi,

i just flashed nightly 108 and afterwards the newest Dalingrin OC Kernel. After booting i get into a loop: When CM sign appears the rotating arrow is shown for a couple of seconds and afterwards the CM sign appears again and the procedure starts newly. Is there something how i can break this loop without loosing all my data?
[Nook Color Android Development] ionepig:
my NC is rooted with nightly build 87. I read the op on updating to latest build but my NC just does not update. I put the nightly build 108 on the SD card, no change to file name. Reboot NC to recovery mode but it always jump to the andriod start up. anyone has encounter this prob? the clockworkmod is updated to latest from andriod market.
[Nook Color Android Development] verygreen:
looks like some service is not starting that prevents the android startup.

If you are not keen on connecting with adb and checking logcat output, just reflash some previous nightly that was already working for you.
[Nook Color Android Development] verygreen:
If you have the "loading..." white text when booting, try updating the u-boot.bin file with the one from update 1.3 referenced in the first post.
