[Q] Does my N1 have a RAM defect? - Nexus One Q&A, Help & Troubleshooting

Up until a few weeks ago, my N1 worked fine. Rooted, CM7.
Then I got lots of FCs and decided to re-flash CM7.
It worked fine for a week or so until last night. It was fine before I fell asleep but dead next morning.
I can VOL.DN + POWER on and switch between FASTBOOT and BOOTLOADER/HBOOT
I can boot into ClockworkMod recovery.
Booting CM7 presents coloured X; then a blank screen (it may be off) and sometimes I get softkeys lit or flash once. Usually N1 vibrates slightly every 5 seconds or so. Only way out of this is to remove battery.
I have a very recent backup. but it or any of it's img files have MD5 errors.
So, either this image is bad, or perhaps I have a RAM error that also prevents phone booting?
Is there a log file I could look at (I can connect using adb)?
Is there a way to test RAM? Is there a PASSDIAG.ZIP or PASSDIAG.NBH image I could try?
I also tried re-flashing CM7 - no change.
Any other ideas?

Did you try to use another SD card to use in your device? It could be a SD card failure and is easier to fix than a RAM failure. I also remember reading in other threads that a SIM failure could make reboots and freezes in these devices
I had a similar problem in my Nexus One with the original ROM, but in my case I think that the failure was in some corrupted file in the system partition.

Doubt SD card nor SIM is issue
Same defect when SD card and/or SIM removed (except I can not attempt a restore with SD card removed).
So I don't think either is at fault.
SD card mounts fine when USB connected to a linux laptop under FASTBOOT (I think I did this) or RECOVERY.

Mine have a like problem, i only do a full wipe and start without SD and it worked

[Q] Bricked, with Oddities

I went to install Phiremod v4 from the EXT4 CWR. It did something funky and wiped out my internal memory (dont know if its just boot or what.)
Oddly, before I was also using NF on a SD, but now it will not work either. I tried other SD cards, and other rom to boot from, with no luck.
When I power up, it is a blank screen. Oddly enough, when I power up using N+power, windows recognizes it as new hardware for a few seconds, but then fails.
Anything else I can do?
I can probably return it, since it seems there is nothing on the emmc, but want to tinker with it for a while.

I did try to, but it wont even boot from an SD card.
Trying again wont hurt, though.
Hold down the power button non-stop for over a minute straight. Then plug it in and hold it down again.
A few trys of this (mainly while plugged in) has always gotten me out of non boot. My computer shows the same things, even though my drivers installed.

i tried this, all i get is my computer makes a sound like: duh-duh-duh very quiclky, byt nothing else happens...
My Nook will not turn on...
I'll bring it back to B&N and tell them the power button isnt working..
i've only had it for 3 days
When I dd'ed clockwork and then looked at it in GParted, it said nothing was there. But when I put it in my nook, it at least tried to boot this time. Then I tried NF again, but this time it wont fit on my SD for some reason.
Your sd image gets reduced due to the partition of clockwork. You can boot into the clockwork sd card, remove the card, (your nook will still be on and in clockwork) format the card via your computer, put the image you are going to flash, then insert the card back into the nook and flash your zip.
Edit: also make sure you're using the right booyabl we sd for your rom of choice. Nookie froyo requires ext3 format whereas cm7 needs ext4 format.

Usually at that sound my nook powered on...sorry bro

Odd, it got out of the Black screen for about a day, but I had trouble booting an sd card.
Now it is a permanent black screen (the screen is off, not just the color)
I was in the same boat as the OP the other day. Odds are there is nothing wrong with the device. Its almost next to impossible t obrick a Nook. Speaking for myself for whatever reason my bootable sdcard was hosed. I went and grabbed a buddies 1Gb card to test and after I redownloaded and burned a 1Gb bootable sdcard IMG all was good to go again. that said if you have a spare sdcard ( any size ) I'd downlaod the current 3.0.1.0 IMG and burn it to the sdcard. Once done toss the card in the device and power it on and it should boot directly into CWR off the sdcard. If it does power down and then move a ROM over to the sdcard and frie it up again so you can reflash it
Edit: Most current bootable sdcard IMG file can be grabbed from here Post#4

Ok, I will have to pick up a new mSD card sometime.

[Q] Nexus One Randomly Rebooting

For the past few weeks, my phone has been randomly rebooting. I would say about 20 times a day. I cant nail down a pattern. Sometimes its while im using it, sometimes its while its idol. Here is what Ive tried so far:
Reinstalled Rom (different versions)
Reinstalled DT A2SD
Whiped Everything (dalvik, SD, and everything else).
Formatted SD card with Amon_RA's recovery.
New Battery
I've tried running a logcat, but this doesn't tell me anything. It just stops when it reboots.
The only thing I havent tried is purchasing a new SD card. I want to see if I have any other options before I do that. I feel like there is something i'm missing. Ive read something about formatting the SD card in windows, instead of in the phone. Are there any other things I can do to troubleshoot? Log's I can check?
Phone Details:
Nexus One
Amon_RA Recovery
CM7 Nightlies
16GB Class 10 SD
DT A2SD
EXT3 SD partition for apps & Dalvik
Thanks for any help that can be provided
It's a known hardware issue.
You have to send your device back to HTC for repair.
I've seen a few claims that similar problems are actually caused by a bad SIM. I've no idea how accurate this is, but it's easy enough to test...?

not accepting SD card/install on emmc

Have had NC rooted w CM7 since April w no problems.
As of month ago, SD card has not stayed in. Seems spring that locks card in is junk. Tried other cards and same thing so has to be hardware.
Because of this, can't download any files, update CM7, CWM, etc. Total bummer.
Can I flash CWM and CM7 directly to emmc or is that impossible w/o SD card?
Have searched multiple forums for resolutions to this issue but no one else seems to have this problem.
Would hate to lose this functionality and have a crippled NC.
Thanks in advance
I never done that but according to my read, you have 2 options
1. Flash CwMR (aka ROM Manager) into eMMC and using it.
2. If you can get ADB working, you can push stuff over.
I had exactly that problem and it happened right in the middle of an update and would not reboot at all. Here is what I did:
Fished out my original, bootable SD card with Nightly 86 and the apps pack, put it in the slot and held it all the way in. Booted up and reinstalled CM7 to the eMMC. (I did not wipe anything but Davlik so I still had all my apps and settings. Then, rebooted into CM7 while holding my regular SD card in place, opened ROM Manager and reinstalled Nightly 201. (I had to hold the SD card in throughout this process to complete which was very strenuous.) Now I am back to where I was, except the SD card slot is basically useless. I called in under warranty and a new Nook is on the way. When I get it I will go through this tiresome process one more time to revert the current Nook to stock before i return it.
If you were only running CM7 off the SD card and still have a functioning stock Nook, forget everything i just said and call them up to request a replacement under warranty. If your warranty is over, you are either stuck with stock or you will have to root the way I just mentioned above.

[Q] CM9, Encryption, and Locked SD Card

So I installed CM9 on my TouchPad, Alpha 0.6. It's been running fine for close to two weeks. I went to turn it on after it had been sitting and charging (it was at no lower than 60% when I hooked it up), and it wouldn't turn on. I tried all combinations of holding down the various buttons nothing worked. Then, out of the blue, while trying to figure out that problem, it held down power and it turned on.
So it started booting into ICS, but instead of the home screen, it said that the encryption failed or something, and that I had to do a factory reset. I booted into CWM, and tried everything, including re-installing from zip, installing Alpha 2 from the zip, wiping the SD card, doing a factory reset...everything. Every time, I go back into the SD card and all the folders are still there. That's making me think that the SD card was locked by ICS somehow, and now isn't letting go, and as such, nothing can wipe the system.
Any ideas for a fix to this? I love CM9 on the TouchPad, but...this sucks.
Wow, nothing, eh? I've tried everything I can think of; the tablet is getting stuck at 12% when I try to run WebOS Doctor (and yes, I've tried every "stuck at 12%" trick I could find), and in general, it appears that writing to any part of the device is locked. I guess I'm going to warranty return it back to HP, unless anyone can think of something brilliant.
Can you boot to webos, maybe if you take the sd card out? If you can, do a full secure factory reset. Also try formatting the sd card (backup your files to your PC). You should try with another sd card also . If these don't work I guess HP warranty is the way to go. Take the sd card out before you send it back. Good luck.
Thanks for replying.
Yeah, I can boot into WebOS, but any changes I make there don't keep (i.e. if I install an app and reboot, it's gone when I get back). There isn't actually an SD card in the TouchPad, the internal memory just gets partitioned and made into an "SD Card", so that's out.
Probably just going to have to send it back...
Duhh! I knew about the sd card and the TP, I was thinking about my cell phone.
Try calling HP's butler service. I've been lucky, the guy I talked to was knowledgeable, but I've read that you can get someone who's useless.

Nook might really be dead - HELP!

I am helping a friend with his Nook, and i've run out of options for fixing it. I have gone through every help thread here, tried things I've found on other forums; no love. I'm hoping someone can review the situation and maybe point me in another direction.
I don't have the exact history on this Nook. I believe that when it was last working it had an early ICS (full-o-bugs) ROM installed on the eMMC. It's definitely been rooted/rom'd/cwm'd in its life.
Here's the status:
--The battery is working and will charge to "green" status. Leaving it unplugged for a few days then plugging it back in will result in "orange" charging back to "green".
--There is no visible indication that the Nook is turning on. Holding the power button for a few seconds up till a few minutes never engages the screen backlight, or any other sign of startup. Same goes for holding "N" with power, holding either/both volume buttons with power.
--If I plug the Nook into a PC, the PC's device manager shows a device connecting (OM??? or something) for maybe one second, then drops off immediately. Unplugging/plugging after that will result in no connection attempt. However, if I unplug, then hold the power button for around 10 seconds, then plug back it, it will attempt the brief connection again. Same goes for just holding the power button down while it is connected, after around 10 seconds you'll see it connect and immediately drop.
--The above situation occurs with the SD card removed, or with a "boot imaged" SD card installed. I'm using a 2GB card that has been setup using Win32 Diskmaker and the ISO downloaded from the Help thread here. I believe it has CWM 3.0.2.8 on it.
--Have opened the back cover and disconnected the battery for as long as a day, no effect.
My assessment here is that the device is still functional, but it is unable to boot. Or whatever it is booting to is immediately locking it up. I really appreciate any guidance here; I hope I can help my friend get his Nook running as beautifully as my Phiremodded one is!

The first step I think I'd take here is to create a working bootable SD card with CM7 on.
Follow the verygreen method and use the latest CM7 from the MiRaGe thread.
http://forum.xda-developers.com/showthread.php?t=1000957
http://forum.xda-developers.com/showthread.php?t=1344873
Use win32diskimager to create the original SD card from the verygreen img file and use a real USB card reader not a slot on a PC. Using other methods can result in cards that won't boot.
You can do all these steps on your Nook without endangering or changing its contents because all this is doing is creating a bootable SD card with CM7 on that you can check on your Nook.
Once you have that working just put the Sd card in your friend's Nook and it should just work.
Having proved that you can then choose what to do next. E.g. You could repeat the process but create an SD card that will load a ROM to the internal emmc memory using the Eyeballer method. If you do that DON'T put it in your Nook as it will change yours.
If I read this carefully enough...you are booting to a black screen, right? In many cases the nook is working but the back light isn't coming on, sometimes because of an erased partition. If you still have an intact ROM partition in the emmc, then you can do the 8x failed reboot, and it will return to out-of-the-box stock.
It can be a little tricky w/o a screen, but hold down the power, n, and both volume keys for 8-10 seconds. The nook will turn off and restart (I believe it restarts, if not do it manually, this is from the top of my head) as soon as it starts booting (1-2 secs) do it again for a total of 8 times. If you let it run too long the process will have to be repeated, so if it doesn't work the first time, try the entire process again.
If it works, it will restore the read-only-memory partition that holds the b&n factory firmware. To be safe, login to the b&n registration, go into settings and do a factory wipe from within the settings. Then you can restore a backup or start over.
If this doesn't work, then you may have wiped your ROM partition, which requires a little more aanced work. Post if it doesn't work and I may be able to help if neither the bootable sdcard or reset methods fix it.
Update: I tried the 8 failed boots thing and wasn't able to get any response from the Nook. It's kinda difficult to know if you're doing it right though when nothing ever lights up on the Nook.
I tested the SD card on my Nook (the functional one), and it does work. The bootloader had the little skull and crossbones guys, and then it loaded up CWM.

So the SD card from your friend's Nook which doesn't do anything in his machine will bring up CWM in yours?
I think this could mean one of two things. The SD card may be booting through to a CWM install on your emmc and therefore when used in his machine with a screwed up emmc then it doesn't work. Or there is some dependency on the emmc which is also allowing it to work in your machine but not his. I'm not sure what these dependencies are but I could see that if it was a full OS like CM7 then it may need a working emmc ROM partition at least, but CWM I thought was pretty much independent when run from the SD.
I still think your best initial bet is to prepare a new SD card on your machine with even a basic eyeballer CWM boot. Prove it works on your machine and then try it on your friend's. That at least proves that it is functioning hardware wise and booting as normal of the SD.
Well
You could take it to B&N even though the warranty was voided
