[Q] My Nook refuses to boot or power on. Help! - Nook Color Q&A, Help & Troubleshooting

I have been running the kanged builds of CM9 for a while, but it began to get bogged down recently and would freeze up almost daily forcing a hard shutdown and reboot.
Sometime yesterday, it began to boot only into recovery no matter what option I tried in the Cyanoboot menu. From there I tried a factory reset and wipe dalvik to hopefully get back into CM9 and here's where the strangeness really kicked off.
Clockwork (which was running off emmc) would freeze in the middle of the factory reset just like it would when CM9 was running (the graphics would degrade slightly upon inspection of the screen).
So, I grabbed my old sdcard with clockwork recovery on it to boot from sd, and I run into the same problem again. Freezing before a wipe, factory reset, or install from sd can complete.
Now, after each failed attempt in clockwork (sd and emmc) it sticks at a backlit black screen and after a hard shutdown refuses to boot (sd or emmc) for about an hour, only to repeat the madness again.
Does anyone have any ideas what I can try from here or familiar with a similar situation?
My sd clockwork version is 3.2.something and I've also tried 3.0.1.something.
UPDATE: For reasons unknown, my Nook seems to be booting regularly as of this morning. However, I am still unable to get a successful flash out of any rom. The closest I've gotten to success is stuck in a boot loop. I think from here I'll likely be able to figure it out, but just as before...
Any help is welcome and appreciated!

I had the same problem with the black screen when trying to install different roms on mine. I just kept clicking the power button and after a few minutes it would kick back on every time.
There is an entire thread specifically on this
http://forum.xda-developers.com/showthread.php?t=949699
As far as CM9 I can't help you much there. I would just try to install a different rom, and hope that works.

Thanks!
I had seen that thread, but I thought my experience was a different; either way, I've managed past that problem using a method similar to yours.
If this helps any, I have been trying to to 7.2 RC1 for a while as well, but it will not get me any further than the stuck boot screen same as the CM9.

Have you tried to follow the tread on returning it to stock ?? I would reformat and repartition it and return it to stock ... then make sure it runs. After that I would try to reinstall the new roms ...
Just my 2 cents

[Q] Need help for my Vibrant

Here is the story. I've got my Vibrant as a replacement for my older one two weeks ago. The old one had a problem with Home button responsiveness and at the end I decided to go with replacement. After some testing with identical firmware (freshly flashed) on both phones I found that the the new one boots much faster - around 12 sec difference (the time my audio widget is fully loaded) and overall I was very happy, until today when my phone screen turn of during some work on the browser. The buttons light was on and the screen became black.
1. I did battery pool. First boot was very slow. Force close for some koush process ( probably clockworkmod) came out .
2. I did 'wipe cache' - multiple force close after that
3. Factory reset - it was somewhat booting very slow and I decided to go with Odin.
I was able to put the phone in downloading mode and flash JFD with repartitioning. Everything looked ok during the process, but after reboot it plays Tmobile animation, startup sound, shows the letter S and stucks there.
I am able to get in stock 2e recovery. If I choose reinstall packages it goes to clockworkmod recovery (I thought clockworkrecovery should disappear after flashing with odin, but it is there) I tried flashing different usb ports - no difference.
The phone was with stock JI6 firmware, rooted with OCLF, ROM Manager with clockworkmod installed. Was working fine till today. I didn't experience any lag issues and neither of the lag fixes were installed or tested.
I played with clockworkmod recovery options format: system, data, sdcard.
I was not able to format boot - some error.
I am not a very good writer... sorry if somebody gets upset.
I will appreciate any help or idea.
Thanks
Fix for your problem
Sounds like some of the rom is either corrupted or the factory reset did not have J i-6 in it.......not enough info. Personal message me and i ll help you fix this problem.

Tried to install CM7 - now I can't get anywhere.

Hi all,
I'm having a little problem. I have researched but everything I've found leads me back to square one...
So I followed this guide to installing CM7 on my M2. Please note that I have in the past successfully rooted my phone, installed the Argenstone ROM and one other basic Great Britain Rom. So I'm not a total nub. However at this stage I have a phone that's is useless to me...
My phone is rooted. I have Droid2Bootstapper installed and I managed to get the CWM 3.X installed. I downloaded the all-in-one.zip file from the CM7 ROM thread (the zip is actually called EndlessCM7-110901-nightly_build.zip - hope that's not an issue?)
I booted into CWM and applied the EndlessCM7-110901-nightly_build.zip and after (without a reboot) wiped everything (I had backed it up previously).
I rebooted the phone and...well I get the Google logo with the Motorola M and the Cyanogen bot as the 2 'O' characters. Then after a while a 3D rotating 'square' and the android writing and logo 'shimmering' in and out but that just goes on forever. I left it for an hour at one point and just gave up.
Now I can't even get past the Google logo. I've tried restoring my previous back up but that won't work either. I can't boot into the OS to actually use RSD lite to flash a known working ROM over the top.
When the LED turns blue and I hit the volume key it displays "Android BootMenu <v1.0.3>" which is different to the CWM 3.X that I was getting prior to applying the EndlessCM7-110901-nightly_build.zip file.
From here I can select to recover the last 'latest recovery' which when done loads into CWM-based Recovery v4.0.1.6-defy.
Basically I'm at this point where I seem to be able to load just about every boot menu under the sun and do everything but actually launch the damn OS.
How can I get out of this hole? Preferably I'd like to get everything back to the stock ROM the phone came with so that I can start from scratch again.
Any bodies help would be more than appreciated.
Cheers,
- Matt
EDIT: I have even used CWM 4.X+ to try and restore the Argenstone ROM. it goes through the whole process of checking the MD5 sums, restoring the system and boot images etc and seems to work without any issues. I then wipe all data and reboot. Nothing - still the same cyanogen Google logo and the only thing I can do is boot into all the CWM menus.
*sigh*
Argh feel like a true idiot now. It took me about an hour of searching earlier but I've only just found/remembered how to get RSD lite to see my phone (pwr+volume+camera) and I'm wiping the whole thing to the factory (vodafone) ROM. Might take the opportunity to take it to Vodafone and tell them it never gets a damn 3G connection lol...provided this flash works (touch wood).

[Q] Nexus 7 boot problem-kernel/rom issue

Hey there! I was updating my version of Paranoid Android and my kernel and it seemed fine at first but It yield some odd problems. I went into Clockworkmod recovery and Flashed my rom and kernel I then proceeded to wipe my cache and dalvik cache. I have done this many times before on many devices. I encountered a problem when I rebooted for the second time, I got the Android is updating apps display and I continued to get it every time I booted. The device would also randomly turn off when the screen dimmmed. I proceeded to set out and fix it. Here are the steps I took and the problems it caused.
Flashed stock rom-would not boot properly
Flash RESET kernel-I messed up and though this was a real kernel, my problems escalated from here.
Flashed stock rom and recovery.
Flashed reset kernel and then real kernel-Still had problems.
Flashed stock rom
My problems from all this accumulated somewhat and I can barely boot into fastboot. I get weird static screens and weird white noise sounds. It does not always let me boot into android and will get to the google logo 1 out of ten tries.
These is really unnerving and I have no clues whats what.
Note: I am using Faux123's kernels and his reset kernel.
Thanks a lot for any help!!!

[Q] Fastboot flashing stock didn't fix bootloop?

TL;DR: I have flashed the stock 4.2.1 image through fastboot, and yet my n7 wifi still reboots continuously at the google screen with the little unlocked lock.
Background: I have had the device for about 3 months, no real problems with it before this. I was reading yesterday night and i fell asleep, and thus instead of being on my desk all night the device was under a blanket. When i woke up, I opened the cover and found it on the google screen with the lock. It was warm, but not incredibly so. I thought it was weird that it had rebooted and apparently frozen, but i held down the power to turn it off. when i turned it back on, it started the google screen, then went black, then started the google screen again. Seems like there may be some sort of a kernel issue that is keeping it from booting. The next thing i did was to go into recovery (had CWM at this point, and it was rooted as well but that's a moot point if i can't get into the system.) and i did a backup, then wiped data and did a restore from the backup that i had just made. after rebooting, it made it all the way into the system, and seemed ok. I set it down, and a few moments later it turned off and started doing the loopy google screen thing again. Next, I went into recovery and wiped data/factory reset, and tried to boot up. no luck, still looping. Next, i grabbed the 4.0 toolkit from the dev section and tried to flash the stock recovery from that, but it was proving troublesome so i just downloaded the image myself and fastbooted then replaced cwm with the stock recovery, wiped everything, and flashed the 4.2.1 image. that should have worked, from what i understand, but no, still being loopy. I re-wiped and flashed, tried 4.1.2 instead, that didn't work, and i re-did 4.2.1. after flashing 4.2.1 and then leaving it boot looping for a little while, i noticed that it sometimes made it into the boot animation and then the animation froze and it rebooted and looped more. after a few more tries, powering it off, leaving it for a few min, and powering it on again, it booted all the way to the welcome screen to pick a language and then froze. some number of loops later, it made it all the way to picking a wifi network and froze. I have yet to make it past that point. Thinking it may help, i fastbooted CWM onto the device, so i have a more capable recovery now. I am now going to look into pushing a non stock rom to the device to see if that will help at all.
Any ideas on what on earth could have caused this? Was it just that the device was a little warmer than usual for a while?
Any ideas on how i can fix this? Much appreciated!
Lastly, should i consider looking at sending it back to google? I didn't think there was anything wrong with the hardware, but i'm not sure.
Thanks!
Update: After leaving the system repeating it's loopy boot thing for about 45 min, it seems to have finally booted into the system, and has yet to reboot again. I have no idea why this happened in the first case, nor why this finally worked in the end, but so far it seems ok.
More: Ok, so it still seems to be looping a lot. I have no idea why still. I'm having trouble getting it to boot back into the system, so hopefully something helps fix this.
Ok, so a day later it seems to have settled down such that there's very little looping on the google logo screen any more; now it just tends to randomly reboot when in use. this is quite frustrating, but seems more similar to what others have reported to be the case with 4.2.1. oddly, i never had these reboot issues before it decided to fail the first time, so i'm not sure if this is just because ii'm on 4.2.1. I may look at flashing back to 4.1.2 and staying there, i suppose it can't hurt. does anyone else have any ideas as to what could be going on?

S4 hung on boot

I restarted my S4 this evening and now it won't boot past the SAMSUNG logo. I have tried a variety of things to get it going but none have worked.
1) Soft boot
2) Pulled battery and let it sit awhile
3) Tried to boot into Safe Mode (stuck on the same spot with no indication of going into safe mode)
4) Wipe cache from CWM recovery mode
5) Reboot from CWM recovery mode
Everything is pretty well backed up but after looking at my sdcard it appears that my camera reverted to internal memory about a month ago so I am after any ideas to get those images.
My phone is rooted and running an old 4.2.2 stock Android OS with USB debugging enabled. I was wondering if by re-flashing the OS it might fix the boot issue and be able to recover the images. Or maybe even flash CM. Or maybe some other thing. I found something about adb but I don't want to do anything else yet until someone more savvy than me weighs in.
Unless it's a hardware issue, then flashing a ROM might work.
The other option is to try a reflow. Reflow means heating your phone up so that the solder becomes liquid and any cracks in the solder (which can cause a bad contact), or any piece that isn't seated right, will be remedied.
did u tried to flash stock firmware using odin?
Deleted
I got it going. I first spent a number of hours getting to know adb which was a dead end because I couldn't get it to see beyond the base directory. I then just flashed the stock rom and everything was there including things that shouldn't be like apps, contacts and texts. The phone is back exactly where it was before it boot locked without having to mess with a single thing. I am grateful but a bit confused.
