I had the same problem, turn on my nook remained loaded in 99, which was to remove the sd memory and finally finished loading and lit, that was my solution till I discovered I had to format my sd memory in FAT32 format then of this I have not had any problems
sorry if I have drafting errors, English is not my language and I'm using google translator, I hope that works for them greetings
My nook hd was fine until over thanksgiving they offered Fifa soccer for free(usually like 6 bucks)..then the trouble started...library kept syncing over and over..podcasts took forever to download,battery drain and finally the 99 percent problem...my nook hd did a factory reset on its own(much to my dismay)..but its working again..for how long i dont know...so looks like google play games might be the cause of everyones problems
Sme thing happens to me, I am stuck on 99% Wont do anything further, I held the home button and on off button, it does turn off, but when i turn back on , I am back to square one... stuck on 99% , This is obviously an issue with BN and this update. Fix it soon . Give us instructions that would work. This is really bad as i hve 2 nooks ... What are you doing BN?
You have to hold the nook button and the power button when you turn it on, not when you turn it off. Keep holding both buttons for several seconds during the startup.
Ours seem to do this everytime it does an update... Ours wont let us do a soft reboot, I have to do a factory reset... This is the 3rd time now... I am tired of this!
I'm had mine for 10 days and this issue showed up yesterday. I came here to find it's very common. The 99% thing started and I couldn't do anything with it. As the day went on it became very warm. I didn't know about the factory reset til now and during the night I feared it fried itself. Unless the battery just wore down. I will try charging it and try the reset. BUT I have not put anything on it, no apps, no games, no google anything. All I did was signed up with my local library. And I am the only profile. I may be going back to the store today.
When people with this issue come into the store I work at we do a couple of things. First, as many have described in this forum, we do a factory reset. But, the next thing I'm always sure to do is reload all the software updates up to 2.1.1, which addressed this issue. As a store, we have been provided with a micro SD card with the updates loaded on to it. Once we do that we download 2.2.0 for you via wifi and help you reregister your nook. We have had good success with this solution.
Also, I always make a note that the customer is having this issue in a system we use. Nook specialists at all stores and our 1-800 number can log into and see this information (it is logged under your serial number). At our store, if we see that you have had this issue in the past and that our solution has been tried, then we replace the device for you under your warranty.
We have not been able to make a correlation between use of a micro SD card or temperature. We are looking into the other correlations (profiles, Google Play, etc).
One thing we recommend to our customers generally, but especially if they are reporting temperature or battery issues, is to install a battery monitor app. My favorite is GSam Battery monitor. It can be purchased through the Nook Store ($1.99, with a free trial available) or Google Play (free). That will record the temperature of your nook as well as battery usage, and what is using battery power (screen, specific apps, etc).
I hope that this will help some of you.
Interestingly enough, we bought 4 Nook HD+ devices for Xmas for our 4 kids... we have had several devices black out / reboot during game play (yes... one of the main reasons we bought the nook for our kids - 12/10/8/6). I'm guessing this happens when the processor gets too hot? I'm wondering if this is also case dependant? We bought B/N cases though the kids bought different varieties...
However, this was quite manageable until the other day when my sons Nook HD+ just froze up when we were switching profiles (to an "adult" profile, having more access and having a password to key in on). It seems many people report this exact same thing happening. So we clearly aren't alone. I'm wondering what B/N response has been... is there a fix coming? Does B/N know about it and are they working on addressing it? Similar to another writer, we spent $600 on these devices and it will stink if the answer is to be doing hard-reboots all the time (resetting all the kids games, which can lead to quite a bit of disappointment). Or many people have said B/N simply hands them new devices (which again, is great, but not a solution as I see people saying they are on their 2nd... 3rd device...).
So to try to figure things out more, it was striking reading "kmm76" post about when she installed temple run (and hobbit I think). Of the 4 devices, the one having the 99% bug now we uniquely had just installed temple run, temple run 2 and then a day or so later, we installed clash of clans (which has been on the other 3 devices for a week or so) and my singing monsters.
I think the more details people post (what games and apps they have installed) we may (as a community) be able to help B/N determine if there are problematic apps. I know for me we won't be installing temple run or TR 2 on any of the other nook devices....
Can other people chime in on whether they have TR or TR2 or these other apps installed? Maybe some other apps?
This clearly "ruins" the device if the solution is to hard reset it on a periodic device...
I went to a Nook HD/HD+ class at my local store, this past week. The guy said to get the 2.2 update via your computer and put it on the Nook by USB cable, that the WiFi stream seems likely why we are getting bad updates.
I'm sorry to hear that some of you are still experiencing this error. Our recent update 2.2, has a fix for this very issue. If you aren't already updated, please download the file here:
For anyone still having issues, please follow the steps to reset your device (erase/deregister) via the setting menu.
Finally, should you still be experiencing a problem please contact us via Chat or Phone support.
We can't get to the Settings menu if the device is stuck when loading from a startup, stuck at 99%. At that point you only have buttons and the power cable to manipulate.

Passing along more information if it will help. My Nook HD is at version 2.2 and still had this issue happen. One thing I recently did was create an additional profile where one of them was password protected. When the initial problem happened, I was logging into the password protected profile. Everything froze and upon rebooting was stuck at 99%.
I was able to resolve the issue by doing a factory reset. I'm just hoping it won't happen again.

Both of my Nook HD+ have the latest software updates and they both just did this to me the other day. Not a good day for me as I was home with a sick lil man with autism who just wanted to read his book!
The 2.2.0 update didn't help with this problem at all!

Mine has stuck and nothing is helping. it charges supposedly, but Ihave tried holding the home and power buttons for a minute, nothing. I was switching between profiles and it froze, then cut off. Now; it will start booting up , but stop at 99%. Is there any hope???
