Hello you all...
I am an idiot living in DFW area. I have had my nook color since last November and beginning of this year, I've rooted the bloody machine. I don't know what I was thinking. Everyone told me that the process takes only ten minutes or so, and it took me two full days. I should have known that I wasn't smart enough to mass with the machine and should have left it alone.BUT, I did root using the auto rooter file.
This afternoon, I decided to take my nook color back to its default setting and did the 8X thing before preregistering first. Now all I see is the scratched up "n" logo with" with the flashing "color" written beneath and the sickening green robot and the "nook color devs" logo at the bottom right.
It was a gift from my husband which means a lot to me, and I am not in position to just chunk it and buy a new one.
So, is there anyone living in the DFW area who can help me in person. I am only asking this because I am not smart enough to follow all the suggestions and directions that I will get (hopefully). I can show my appreciation to your help with small amount of B&N gift card. Please let me know if there is anyone who is smart and kind hearted to help me out.
Thank you.

You didn't do the 8x thing... be patient and try again, sometimes it seems like a 9x or 10x thing. I have done it a couple of times and just resorted not to count but to keep stopping the boot until it starts booting with the update screen.

Hi bluepen61,
Unfortunately, I did see the update screen. After the update screen and the installing process was finished, I got stuck in the same screen.
I am so sickn' tired of looking at the same screen, I am very very close to
throwing the thing on the wall to be just done with it!

First, if you were able to get the thing rooted, then you are not an idiot (even if it took you two days). If the thing boots at all (which it does by your description...it just gets stuck somewhere), then this can be fixed. Don't throw it out, and dont get too frustrated.
I know you don't think that you can do it, but I can tell you that rooting the Nook is actually harder than installing a custom operating system of returning to the stock operating system.
There is a good thread that gives you step-by-step directions to getting your device back. I can let you know which steps to follow, and we can help if you get stuck...just post here again if a step is giving you trouble and we can guide you through it. I will assume that you want to return the thing to the original stock operating system. If you want to do anything more from there, then it will be easy because you will already know how to do this.
First, go to this thread:
http://forum.xda-developers.com/showthread.php?t=1030227
Read the entire first post. If you don't understand what he is talking about, that is OK.
Now go to the section that starts with "On with the guide:" in bold letters.
For step one in this section:
Download the sd card image that is linked in the first sentence. It is a zip file, so you will have to 'unzip' it before you can do anything with it. I will assume that you know how to do this, but if not it is quite easy. If you are using Windows 7 or XP, just double click on the file like you would any other file or folder. It will open up as a folder and you will see a file with the extension ".img" in the folder. Just drag and drop this somewhere outside of the zip folder (like on your desktop). There are also specific programs for doing this - the thread references a program called 7zip that you can download and use if you like.
For step two in this section:
Now that you have the sd card image, you need to 'burn' it (or copy it) to your micro SD card. If you don't have one of these, you only need a 1gb card and they are very cheap at places like Walmart. You will obvisouly also need a way to plug this card into your computer. Hopefully your computer has a place to plug SD cards in - most newer machines do. If not, then you will also need to pick up an SD card reader that plugs into a USB port on your computer. You will need to download either one of the programs linked in this step - either "win32diskimager" of "winimage". I use the first one and it works well. Once you have that downloaded, you will need to run the program as an administrator. This is done in windows 7 by right-clicking on the icon that runs the program, and then selecting 'run as administrator'. If you are on Windows XP, it should work fine without this. Once it is running, follow the directions that they give you in the thread - there is a link there that shows you exactly how to run the program and how to select your ".img" file from above. If you have trouble with this, post the issue here.
Now go down to the section labeled "Epilogue" in bold letters. Go to step #4. You want to follow the link in that step to download the file called "update-nc-stock-1.2-signed.zip". Once you have this file downloaded, copy it directly over to your sd card that you prepared above - do not unzip it or otherwise modify it.
If you have gotten this far, then you have done the hardest part. Power down your nook, put your sd card in the device, then turn your Nook back on. You should boot into something called ClockworkMod Recovery. It will be a text-based list of commands. The volume up and down buttons lets you navigate through the commands on the screen, the nook 'N' button on the bottom front of the device is equivalent to the 'enter' button that you press to select a command, and tapping the power button will let you back up one menu screen if you select the wrong thing. You want to use the volume down button and highlight the command 'install zip from sdcard'. Press the nook 'N' button to select this option. Use the volume down button again to highlight the 'choose zip from sdcard' command, and press the 'N' button again. You shoud now see a list of all the files contained on your sdcard. Use the volume down button to highlight the file "update-nc-stock-1.2-signed.zip", then press the 'N' button again. It will ask you to verify that you want to want to do this - select the option confirming that want to proceed and press the 'N' button again. It will take a few minutes, but a message will appear when it is done. At this point, hold the power button in for 8-10 seconds until the machine turns off. Take out your sd card, then turn the power back on. You should boot into the stock 1.2 operating system and your nook is revived.
It seems like a lot, but like I said if you were able to root it then you can do this. If you get stuck, post which step is giving you trouble and we can get you through it.
IN MY INFINITE WISDOM, I replaced my build.prop with the one from a Motorola Xoom in an attempt to get Sketchbook Pro to show up in the market. Now my tablet is boot looping.
I backed the original up in the same directory, as build.prop.OLD. If I could mount system and replace the file with a PC, I'd imagine that the tablet would work again. How could I do that?
However, THERE IS ANOTHER COMPLICATION! I used the 'Acer Phone Disabler' app to remove the telephony drivers, which means that I cannot flash a rom or the tablet will brick. I'm not sure what this means for Nandroid backups.
The tablet has the leaked stock 3.1 rom installed, it's rooted, and it has Clockworkmod recovery.
Thanks in advance for any help!
Oh god.
I used ADB to pull my build.prop.OLD, renamed it to build.prop, and pushed it back. Now... the tablet boots up, and it shows the Android "Welcome" screen. Clicking the only button available doesn't work. It just highlights as if it is selected, and doesn't do anything when I lift my finger up.
I DO have a Nandroid backup from several weeks ago of the same rom, but from BEFORE I removed the telephony drivers. I am only going to try restoring it as a last resort; does anyone have any ideas? Remember, flashing a rom would result in a brick because I used Acer Phone Disabler. Is a nandroid backup safe?
Thanks guys. I'm really hoping this tablet isn't too screwed.
I'm hoping someone else chimes in here but I am under the impressing that the nandroid backup would override any changes you could make as long as you don't break recovery. As far as my experience goes if you had a backup of your current configuration you could do an "advanced restore" and only restore your "system"

Restoring just system worked! My homescreen is back to stock but all my apps are still installed, so I don't really care. Thanks a bunch, I was so worried.
COOL!!!
Glad I could help.

Help needed for a boot loop
Well as said in the video, i reuse an existing thread about bootloop...
I'm stuck in a bootloop with an iconia A500... but let's look at the steps that got me there...
The First mistake was to answer yes to my friend who asked me to connect his Vodafone k3565 to his iconia A500, but as i read Android was linux based and i did use linux a lot as a student, i didn't even imagine it could go wrong...
Tablet was stating to run :
Android 3.1
Bernel 2.6.36.3-00009-9dddf6f2
Build 4.015.05-EMEA-CUS3
i did root with iconia root 1.3
then added Busybox and a terminal program.
reboot, try a SU and could access the devices
Here is the second mistake... i should have wondered how to restore to normal state before starting, because i don't have any SD card that suit the device ( mine are normal sized ones, you know.. Stamp sized :/ )
Then i got to the thread
http://forum.xda-developers.com/showthread.php?t=1058846&page=7
and i used an usb key to transfer it to the device, but before applying the files i took a look to them and found 3 of them would overwrite actual system files, so i did a backup of them :
/system/build.prop
/system/etc/apns-conf
/system/bin/rild
and looking at the build.prop i saw differences in the values of the one on the A500 and the one in the package so i decided to get only the missing lines from the new system.zip file and add them to the original file
And here is the 3rd mistake, and i guess the reason of the problem : i did that merge on a windows computer, and i fear it did add those pesky CRLF at the end of lines, turning my build.prop into a build.prob(lem).
I'm not sure, as i didn't check before it was too late.
rebooted and... boot loop, with 1 times out of 2, the little android with yellow triangle and exclamaition mark.
Cried, runned in circles, then looked on forums to find a solution.
Reboot with Power+Volume gives :
"Erasing cache before SD update...
SD update cmd:recovery
--update_package=sdcard:update.zip
Booting recovery kernel image"
Then i get the android with gears for a few seconds, then below him is a bar like the one in the android store when you download a file, then half a second later, again the exclaimation mark.
I also tried plugging a keyboard to hit the home key...
( in fact two : Logitech G110 and trust easy scroll silverline )
no difference, maybe because those are gaming keyboards and they arent loaded soon enough by the tab, or maybe it crashes before keyboard loading.
Tried then to install ADB using post
http://forum.xda-developers.com/showthread.php?t=1155664
hoping i could use the USB cable to put the backup files back in place but when i plug the device into the windows host, it recognises an unavailable USB MTP device, whose properties say "Acer iconia tab a500" in the "signaled bus description"(translated from french display, may be something else in english)
I manually force added the Acer ADB interface, but both the devices are unavailable to windows, with a warning sign, stating "this device cannot start (code 10)"
"Adb shell" answers "Error:device not found",which is expected, as windows can't see the devices properly
the strange thing is that, with USB plugged from A500 to PC, the Android with exclaimation stays forever, while without the cable, the system boot-loops
so i'm at this point :
i have a boot looping device, and the backup of the modified files on an USB key, and no way to put them back on device.
I found on the forums a lot of different .imgs that could be put on the /system to reload the device but none with EMEA-CUS3. So if i overwrite the files, i can't go back
I read you need a SD card to patch the device but not all of them work...
And my only computer with a SD slot uses a big one, not micro one, so i also need an adapter to write on the sd card.
Is someone near me (belgium/postcode 4000) having a SD ward working with the device who could lend it or help me doing the job ?
else
i saw in a nearby store ad "Sigma SDHC 4Go" or "Sigma SDHC 8Go", with apparently an adaptor for a normal sized SD slot, can anyone confirm it works or it don't work for sure ?
else
Can anyone tell me an SD card know to work, and being sold currently with an adapter so i have a chance to find one in a store near me ?
Is there a way to create an update.zip that will only update the files i did overwrite ?
if not, has someone an image for the same system i have ?
Well... lots of questions, but i'm very worried, especially as the device is not mine and not working anymore atm.
-> update
Looking closer at the modem (Vodafone k3565) it has a trap that says "SD card" so i guess i won't need an adapter... still need the reference of a SD card known to work for the restoring.
[bump] and more :
this thread http://forum.xda-developers.com/showthread.php?t=834144
lists working SD cards, but don't tell with which device. i'd take the guess it applies to the iconia A500 and take the list to the shop to see if anyone is available...
Did you install the Acer USB driver, found here? http://www.acer.co.uk/ac/en/GB/content/drivers
You might need to go into device manager after installing and right click/update drivers on the tablet, then manually direct it to the Acer driver folder. That's what I did, then ADB worked.

The reason "some" SD cards don't work is down purely to formatting. Normally, reformatting them in an Android phone sorts it out. Not always, but normally. Don't worry about the GEN3 stuff too much, it's just regional variations anyway... More important to get the tab working again, no?
Yes i did ( on 2 different computers, just to be sure )...
and still the device is not recognised as "adb device".
Windows shows a "USB MTP Device"
Tried to manually add the "ACER Composite ADB Interface" and "ACER Fastboot Interface" to the installed peripherals, it shows with yellow exclaimation mark, never shows up running.
Without any useable answer about one week later, i did buy a Traxdata 2Gb SD card with adapter ( the cheapest i found with an adapter from micro SD to normal SD ) and flashed with the Emea_Gen3 ROM from http://forum.xda-developers.com/showthread.php?t=1113878.
Now the tablet works, but is telling me 4.010.42-COM-GEN1 instead of the previous 4.015.05-Emea-Cus3.
Seems to work correctly, so i go on with the modem connexion.
My husbands Acer a500 screen froze when he was playing Zimga a poker game when this happened.
He believes he had ICS but he is not sure of anything speciffic.
He doesn't have any type of backup.
He never had it connected to the computer.
We tried the factory reset.
We tried the hard reset.
We cleaned the cache & whatnot...
Nothing helps.
I've tried to use the GUIDE: Recovering Recovery/Obtaining SKB
Of course we only option we have, because nothing was ever back up, connected to a computer. I downloaded unbumtu 12.04 and installed it onto my laptop.
The requirements:
-ubuntu 12.04
-micro USB cable
-paper clip ....
I also made sure I installed gcc, lsusb, libusb-1.0-dev, & libusb-1.0.x
I get it to show on the desktop ...
I type in: sudo su
Then: gcc apx.c -o apx -lusb-1.0
I end up with an errors.
If I remember correctly it says that line 4 and line 5 of EPPE code was in errors.
The another time it states...
Then it stats su: invalid option -- 'o'
I am by all no means a computer code writer, and hope someone will help me solve this issue.
I just can't afford sending the tablet back to Acer to be fixed.
I even tried flashing the information on the micro SD card, but I believe since his tablet wasn't connected ever to a computer things aren't running as smoothly as I would like.
I've downloaded nvFlash, blackthud3r, and many Roms.
I.ve even tried to flash a few with no luck. Mister Android has fallen and can't get up with the RED triangle and all.
I can get the tablet in Apx mode.
Also I can get the screen with the Fastboot...
I've tried all the tricks with the volume up and power button and toggle switch, AND/OR the volume down button and toggle.
But without the UIP or CPUID those items aren't doing me any good.
The tablet was only updated the old fashioned way. No customized anything.
Hubby mainly used it to get email and play pocker over the internet with it.
Not sure what other information you need, but I hope someone could get me out of this MISERY!
Been messing with it for over a week trying to read and get as much information about others having simular situations.
Thank you in advance & Hope to hear from you SOON!
We've even tried doing things in different computers...:crying:

Well, seeing it a stock tab, not a lot of options.
I would try this, here is a link where I gathered 4 500 ICS updates. Note that I named them with build numbers to keep things in order.
Rename one of the files to only "update.zip" (remove the build number in other words).
With the tab off, hold VOL+ and PWR until you see the update start to install, then release both.
Now, if one of them doesn't complete, then try the other. Hopefully one of them completes the install and boots the tablet.

I appreciate you getting back so quickly.
I've already tried these.
I also tried most of these from this web page.
http://forum.xda-developers.com/showthread.php?t=1816560
Nothing seems to work.
There was a couple of them that would install about 25% but then android would keel over and the red triangle of death took over.
I would appreciate if you had any other suggestions, or if anyone else did.
There has to something I can do?!?
Well, without having the UID number, I think NVFlash is out of the question. Usually we get these quite simply when the tab is operating.
There is a Linux solution, to get UID, but I'm not a linux guy. There's a thread about UID, I think in the dev section. In there are steps to get it through Linux I believe.
With the UID, I think we can run TimmyDeans rollback tool. But as far as I know, you have to have the UID number.

Please post the the commands you run and the exact result you get, it is hard to tell what went wrong without knowing exactly what you did and exactly what results you got.
Just a copy of the terminal buffer as it is would be good.

OK - total noobie here.
Bought my first tablet - Acer A500 off craigslist for $100. Worked like a charm for six months then went to brick status - locked on Acer Screen. BOO! HOO!
I've read and done the factory reset with the paper clip, and the Power Volume+, with no results.
Then I said to myself - "Hey, there's got to be a EASY way to do this. Probably download some software to my PC, plug in via USB, probably some sequence to boot from PC, and I'll be done!"
WRONG!
Apparently, I've got to know my CPUID - is that an acronym for Confused Person Undoubtably and IDiot - cause I got NO CLUE on that one.
And I've got to get an EUU - European United Union?
And I've got to get a Russian DeCrypter?
And.... well, you get the idea.
So, I've decided to exercise my capitalistic privileges!
IF SOMEONE THINKS THEY CAN FIX THIS DANG THING - I'LL PAY YOU!
I figure it'll take me days to figure out what I need to do and download and do it. Or, I can just ship this to someone who wants to make a few bucks and we'll both be happy.
So, if someone wants to help me do some additional diagnostics and make a buck or two in the process - email me at my public site of
rainbow 4 jd @excite. com (obviously no spaces there in the actual email address).

Eh, personally we like to keep things in the forums, as other people may want to chime in and offer some steps others haven't thought of.
For some info, I'll try to explain a couple of things;
1. UID number. This is a number specifically assigned to your CPU. (CUID) which allows us (with a secure bootloader key, SBK) do a low level NVFlash of bootloaders. The issue, is that the bootloader (the first thing that loads) is secure and prevents us from flashing things. Pretty much locked. Unless you have your SBK. Then we can get into what we call APX mode which allows us to bypass security (in easy english terms). And yes, we have a tool that converts UID to an SBK.
If you do not have your UID number, all is not lost. Rumor has it that after ICS, the UID sometimes is the serial number you'll find on your Ext SD cover. Now some people confirmed this, and some say no. But it's worth a shot to use that number when trying to run an EUU file. If not, you will have to install Ubuntu on your PC and use the Linux method of getting it. More later.
2. Also, an EUU which is basically nothing more than an Acer maintenance rom which you run from your PC, requires this UID number because it uses NVFlash. That's why it's important to have it.
3. A Decrypter (not Russian I can assure you ) is sometimes required to install factory roms and updates, as Acer delivers these encrypted. You shouldn't have to worry about this yet, as most of the things we have posted are already de-crypted. For reference, you will find the tool in the Themes and Apps Forum.
For starters, I would like to know which bootloader version you currently have installed. You will find this in the upper left corner when you start the tablet. Should be a series of numbers and letters. Use a magnifying glass if you can't read it... :laugh:
Followup to a bricked Acer A500 - and if anyone can repair?

Eh, personally we like to keep things in the forums, as other people may want to chime in and offer some steps others haven't thought of.
For some info, I'll try to explain a couple of things;
1. UID number. This is a number specifically assigned to your CPU. (CUID) which allows us (with a secure bootloader key, SBK) do a low level NVFlash of bootloaders. The issue, is that the bootloader (the first thing that loads) is secure and prevents us from flashing things. Pretty much locked. Unless you have your SBK. Then we can get into what we call APX mode which allows us to bypass security (in easy english terms). And yes, we have a tool that converts UID to an SBK.

First - thanks for the reply - it was VERY NICE OF YOU.
And just so you know - I spent $100 on ebay and bought a replacement! So, now I can totally devote myself to learning what (if anything) can be done to unbrick my old one.
1. There is no external markings on this tablet AT ALL. No stickers, no nothing.
2. When I open up the SD card slot - I do get a SNID of 13001360415
3. When I do Power Volume+ slide - I get "erasing user data" and immediately below it "erasing cache"
4. It then goes to ACER logo screen and stops.
Logic tells me that A) the motherboard (or whatever passes for a motherboard on this tablet) might be bad. It's trying to go through its boot sequence and there's a physical fault or B) the motherboard could be good, but the inherent "boot disk" software is now corrupted - its locking up - and never getting to the OS software.
Or I could be wrong.
In either case - I feel like I have insufficient knowledge to properly diagnose AND determine if this is repairable at all. And that being said, IF someone has experienced this before, gone through the trial and error, and can say.... "Hey, I've fixed twenty of these, no problems" - I will happily defer to their experience.
Anyway - based on symptoms - if you think I have a fighting chance of salvaging this - I am game!

Thanks for the comments!
$100... wow, I hate to say what I paid for my 501 new here in Moscow But now, I use my a701.
Typically, the a50x tablets have a reputation of being "bullet-proof", although lately, seems a rash of bricked tabs. Perhaps just due to old age.
You're correct about the motherboard, more specifically the emmc memory on it, is the likely culprit due to what you've stated. Or.... it could just be a corrupted file. Who knows until we investigate a little.
For starters, lets do some simple stuff first. Following is a link to some ICS update files. There are 4 of them. I have already de-crypted them. Now, download each to a individual folder on your PC. You will see they are numbered. This is to keep them separate so you know which is which.
Now, choose one of them (really doesn't matter which one, but maybe start with the highest number first). Rename it to "update.zip" (make sure it is not "update.zip.zip" as this is a common mistake. If your PC doesn't show the .zip extension, just rename it to update)
Now, copy it to your external SD card. Power on your tablet holding Vol+ (or minus) and PWR. Continue pressing until you see text about installing the update in the upper left corner, then release. We'll see if it installs all the way. If after 15 minutes it doesn't (it may stop at about 25%), then PWR off, and rename and copy the next update file, and try that one. Might have to try all 4, so make sure your tab is fully charged.
If none of these install all the way, then life becomes a little more difficult......

Can I get in on this conversation? For three days, I've been trying to revive my brother's A500. It seems like every option I come across requires the sbk, or the cpuid. I don't have the cpuid and can't figure out how to retrieve it since the tablet appears to be stuck in apx mode. The power button is illuminated and nothing comes on the screen. Windows device manager displays Acer USB Boot-recovery driver.
I've tried using AfterOTA v1.09 to flash recovery and bootloader files, but not sure if I've chosen the correct files to flash. I found a zip file here on the forums that contained ics_boot_unlk_v6_500.bin and recovery_thor17_403.img that I've attempted to use. AfterOTA just hangs on [2/3] flashing recovery...
Not knowing this all important UID, where do I go from here? Can I hear more about this Ubuntu method? Will that help in this case?
Thank you!

Yep.... UID is all important. Uses what we call "NVFlash" to install bootloader and recoveries when all else fails. You UID is specific to each tab. No 2 are alike (as far as we know). With it, we can convert it to an SBK (Secure Bootloader Key). The stuff acer don't really wanna give us. This allows the use of NVFlash via APX mode (which you have already discovered.
Here is a link to getting your UID via various methods. The ones you want to pay attention to, are the links using Ubuntu (halfway thru the guide) Note that you may have to look at links within links to get all the methods people have tried, as some change a bit of the scripts here and there, but you should be able to figure it out.

also of use, is a tool called "babsector". This tries to repair/workaround physical sectors on some tabs. But you shouldn't need that yet. So read that guide and check the links in it for using Ubuntu.Never had to use it myself, so not a lot of further advice on the technical aspect.

OH MY GOSH - IT WORKED! YOU ARE THE HERO OF ALL MANKIND!!
It took me a bit of minor tweeking - in that I had to rename the file BEFORE copying it to the SD Card - because I was getting some copying errors.
The version that took was #3 - what I mean by that is.... it was the third one in the Windows Explorer naming sequence. I don't know what the name of it is now, because I obviously updated the name to be "update.zip"
So..... it "took" and started giving me a working Android Robot - whereas the others had given me a Dead Android with the Information icon.
I waited through the process - it loaded the operating system and prompted me to select language, country, wifi, log in with google, AND I WAS UP AND RUNNING!
I am going to post these results as a specific FIX and encourage everyone to try it who has a bricked tablet!

Hello, from Spain. (Sorry for my English)
I have this problem in my nook simple touch: appears on the screen: "encountered a problem that requires a system restart"
I've tried all sorts of things I've seen in this forum and in others (update to 2.0.1; recoverys, formatting, etc. and nothing works.
I would like to try installing version 1.0.0 of nook, but I can not find the .iso.
Could someone help me? Thank you very much.
Luisa
Do you have ADB working?
A logcat will tell you exactly what the problem is.
Hello
Thank you for contestarrme.
1. The Nook can not be opened.
2. Nor is turned off completely
3. After it seems a restart, the message "Encountered a problem That requires a system restart" appears
4. Nor do I make the PC recognize it.
5. I tried to fix it using this software uy following the instructions of the forum to do so, but without success: "sd_2gb_clockwork-rc2", "Alpha-FormatTouch-2", "touchnooter-2.1.31", "install_stock_1.1_recovery "" NookManager-0.5.0 "
6. Unfortunately I can not find the original Nook software, to introduce it, but would not know how to do because the PC does not recognize the Nook
7. If you have any idea and can explain it, I will be deeply grateful.
8. Final note. I've been looking for "logcat", as I say, but I have not found the way to do if my computer does not recognize the nook. Is it possible to do another modo¿ give me a link where you explain?
9. Many, thank you very much !!
The good part is that the NST is almost unbrickable.
The bad part is that to get things going is a bit complicated.
(I've also lost track of where the stock images are.)
See the thread on OmapLink. http://forum.xda-developers.com/showthread.php?t=2579521
When you get that error, does it restart itself or do you have to push a screen button?
If you're using Windows, does it "bong" when you plug in the Nook?
Does Windows ever say "unknown device" or ask for a driver?
What happens with a long push on the power button?
I'd stay away from these "super-one-click-nooter" things, they aren't very good when something is wrong.
Hello
I try to understand the link you sent me.
Meanwhile, I answer your questions:
1. When you get that error, does it restart itself or do you have to push a screen button?I am the one that presses the button, to restart. If I do not push it, it does nothing
2. If you're using Windows, does it "bong" when you plug in the Nook? Effectively, when connecting the nook you hear the typical sound, but it does not appear between the connected devices (although once it appeared ... I have tested the cables with other devices and they work perfectly)
3. Does Windows ever say "unknown device" or ask for a driver? Never:
4. What happens with a long push on the power button? If I hold down the button, the display remains frozen (read forever). As soon as I stop pressing, it starts to start (nook.by Barnes ...)
5. More: I tried to press the lower left and right buttons, and a message appears that says install failed
thank you!!

Hello
I have been reading the link you mentioned above. The truth is that I find it difficult. If you have any idea (I do not mind putting the Nook at risk) I'm ready to take it. Thank you !!
Hi.
I've been this weekend trying to figure out how to fix my nook. After trying noogie "and not getting anything (the screen freezes with the message rooted forever) I have come to the following conclusion: maybe I could fix the nook with a backup of some person who wanted to give me yours, and then put it in The nook with the program Roadkil's DiskImage.What do you think the idea? Do you think someone would have a backup of their nook that could lend me? Thanks
Sorry, short response for now.
You know that the point of Noogie is just to put up the splash screen, then mount the entire internal SD card over USB?
It doesn't have any user controls after that.
No, i did not know. I thought it was to restore the nook to an original version.
Thank you
Hi.
I guess the silence indicates the few solutions that exist for my Nook.
Thank you very much for everything, Renate. It has been a pleasure.
Gracias!!
Maybe this?

Awhile back, XDA member @the_alternate posted a link for a region reflasher. If you can get the NST to at least reset, you might be able to rewrite the innards by that method. The link is https://sites.google.com/site/xcdguides/nook/nookregion
Sorry for the speed of my response.
It can be a little tricky to get things working, especially:
If you never turned ADB on.
If you never got the Windows drivers working before
If you never made a backup.
Can you get Noogie to work?
Do you see new disks on your Windows machine?
Do you see any "unknown devices" in the Device Manager in Windows?
Hi, Renata. Before writing I tried the solution you give me about the region change, but it did not work. I think I'm asking for something impossible and, besides, making you waste your time. I very much appreciate and very sincerely the help you have given me A way so disinterested, but taking advantage of Christmas I will buy a new Nook.If you think, we finished this topic. Thank you, thank you. I hope you enjoy the year 2017 and everything is wonderful in your life and in the lives of people around you.
