This Thread is outdated!
I will update it soon!
Thanks for your understanding
Hello everybody,
as there is no sub-forum for the new nook simple touch (help to get one),
all information are split on several posts in the nook color forum.
I want to create a central thread which list all the knowledge and work that is already done.
The most solutions are NOT my work!
I will link to the post and add the author,
please thank them for their work.
Basics
Update
There is an update for the nook touch!
(not recommended for now)
Checkout the discussion: Nook STR update 1.0.1
Screen Refresh
To avoid ghosting you can easily refresh the screen by pressing the n button twice (open and close default launcher).
Hidden back "button"
You can easily go back by swiping in the middle of the topbar from right to left.
(You may need this in stock apps / settings, after getting root you get 2 buttons for menu and back on this area)
Hidden Browser
you can access a browser by typing in an url into the searchbox,
but the browser doesn't work well...

Page-Turn Buttons
The main thread is from xboxexpert,
the user aruangra shows how to map the keys to volume up/down so you can use it for scrolling in some applications
Softbutton
Softbuttons can add little buttons to your user interface which simulate the normal android buttons (Home, Back, etc.),
Button Savior is working very well.
OMGWTF_BBQ modded it for the eInk Display.
Market & gapps
If you have already rooted and want to enable the market by yourself you can use the tutorial on nookdevs from the nook color. GabrialDestruir have tested this and confirmend its working.
Additionally i have written down some steps to activate it by using resources of the touchnooter script.
GabrialDestruir updated his script, i dont know if my tutorial still works
AFTER you get the market working you can
update the market and gapps
or, just update the market.
This will fix the market search too
Language / Locale Settings
If you live outside of the USA and managed to get a nook,
there are a few steps to customize the system to your locale / regional enviroment.
To change the system language and the keyboard you can look here:
customize language
Timezone and 24:00 Clock can be set on the default settings menu
(On first-start-setup you can only choose US-Timezones)

What's the consensus as to the best launcher to use...
I currently use ADW, which seems to work ok. Biggest complaint is I can't see the text on the settings menus...

I prefer a white backgounnd. So ADW seems to be an only option. I am using ADW EX.

updated the fist post,
thanks to DenisTheMenace for the info about adb usb drivers,

iam using ADW too,
i like it more than Go Launcher or LauncherPro
but when i tried them i recognized some empty settings menus too,
so i dont think its the launcher that shows the settings menus without text...

It's not without test, the test is white on white background, that's why we don't see anything.

I got pulse to work, I used the pulse from the nook apps shop.

mkenney12 wrote me a pm.
he wants that everybody consider the consequences of using a rooted nook touch.
its definitely a point that everyone has to keep on mind!
rmkenney12 said:
Hi,
I'm not sure who to send this to in the xda-dev
community, but noticed that you were maintaining
the KB articles for the Nook Touch root. I tried
posting to the touchnooter dev thread, but I don't
have the requisite 10 messages, so I couldn't even
thank them.
I've been able to root my N2E with the
touchnooter root: the most recent 1.6.24. I'm
extremely happy with the results, but am having a
major concern that doesn't appear to be getting
proper coverage in that or other roots. (I initially
tried the noogie root with lesser results).
<Rant On>
IE, adb wireless/wifi access.
Nobody seems to be expounding on the fact that
it's an enormous freaking barn-door-size gaping
hole in the security of the N2E(or doing anything
to eliminate it). You yourself mention it in
passing in your KB article, but only give it a single
line.
Essentially, once these things are rooted, they
are -enormously- vulnerable if they are taken out
into the public, either at a Barnes&Noble store,
or at any other hotspot. All it takes is for a hacker
sitting there at that hotspot with a laptop, scanning
all of the IP's in that subnet for IP's that respond
to the adb port, and they can do a simple
#adb install MyFavBotController.apk
or somesuch thing. If adb pukes on them(IE, it's a
non-rooted Nook), then they just keep scanning.
Unless you're sharp and see the notification tab
popping up, you may never notice it. They can
install any freaking thing they want on your Nook.
Evetually you've got hundreds or thousands of
infected Nooks running bots, or some other fun
little thing(s) implanted on them.
Everybody seems to be incredibly happy about how
easy it makes their experimentation, and all of the
root developers seem to be focused on making sure
that adb wireless is enabled, either in the startup
scripting or even in the uRamdisk as with the
touchnooter root.
Sure, you can install the adbWireless app from the
market, and it will turn off adbWireless, but:
a) when you initially run the adbWireless app, it
doesn't even properly report that the adb wifi
function is on. It reports it as off, even though
it's actually still responding to adb connects.
So now you have to remember to turn it on,
and then back off. That does work(for a little
while).
b) it's not permanent with some roots, like the
touchnooter. I disable adb wifi with the
adbWireless app, it's off, and everything is nice
and safe? if I put my N2E through a power
cycle, guess what. It's been turned right back
on again. That's completely whacked.
1) For one thing, as an older person I may
forget to use adbWireless to keep turning
adb wifi off after power-cycles. Over and
over and over again.
2) Even if you remember, there's a window of
access during power-up that's about 30-60
seconds long before you'll be able to run
adbWireless to shut things down. A hacker
could do a lot of damage to your Nook in
that time.
3) I have heard rumors of Nooks turning
turning themselves back on after being
powered off. So now you could be in a
hotspot, your Nook could turn itself on in
your knapsack without you even knowing,
and the hacker sitting there has all the
time in the world to beat on your poor little
Nook.
It's BONEHEADED. adb Wifi should NOT EVER be
automatically turned on by the bootstrap. NEVER.
If developers of these roots want to make it easy for
the users or other devs using them, then simply
bundle the adbWireless application along with
SuperUser, Yahoo, and the other apk's they've
included in their root distro's.
Let the -users- decide when and where it's safe for
them to use adb Wifi. Devels are NOT doing them a
service by forcing adb Wifi on them, or encouraging
them to use it under dangerous circumstances.
</Rant Off>
Sorry, but I have a rooted Nook that I'd like to take
outside the confines of my home. Unfortunately,
I don't dare to now. So yah, I'm feeling cranky :-(
rev0l. -please- pass this on to any developers
you might have contacts with.
Thank you!

i dont know if someone can disable the access over adb by default...
may you can use apps like tasker or automate it to disable wifi when your accesspoint is not in range or start the adbwifi app while connecting to a public wifi.

I love Zeam.

I think that the best way to avoid the wireless adb security hole would be to enable adb over usb and disable adb wireless if it is possible.
I have read on irc someone (maybe JesusFreke) saying that we just have to do something like modifying adb or doing something else (I don't remember very well)

I'm also trying to find out how to adb with usb. In particular I'm looking to get my N2E to connect to my iPhone running MyWi 4.0. I've read that the nookdevs Ad-Hoc_WiFi wpa_supplicant file for the NC will work with the N2E, but I haven't found a way to connect with USB and I'm too scared to try it over wifi in case it goes wrong and I won't be able to connect with adb over wifi to fix it. Any help would be much appreciated.
Edit :
Managed to get ad-hoc wifi working by pushing the fixed wpa_supplicant.adhocfix file to the /system/bin/ folder with adb over wifi.
Then, I switched the wifi off on the N2E and opened terminal emulator and did the following :
Code:
su
adb shell mount -o rw,remount -t ext2 /dev/block/mmcblk0p5 /system
mount
cd /system/bin
mv wpa_supplicant wpa_supplicant.old */make backup of original wpa_supplicant file/*
mv wpa_supplicant.adhocfix wpa_supplicant
chmod 755 /system/bin/wpa_supplicant
exit
I am now able to connect to my iPhone's MyWi hotspot.
For security when connecting to a public hotspot, I have installed the ttxapps wifi adb app from the android market and turned off adb over wifi, meaning I can toggle it on only when I wish to connect on my home network.

does anyone have system restore image?

another pm from a user that cant post
J.Harmon said:
I figured out how to get a full factory "re-image" of my nook touch.
I followed the instructions for the nook color here:
Method two: Set the Boot counter to 8 by typing
http://nookdevs.com/Flash_back_to_clean_stock_ROM
I rooted my nook touch using touchnooter. Loaded up the amazon app store and played around for a while. But I found after I rooted the nook that the nook store didn't work any more. So i wanted to get back to factory state. I then installed the wireless adb app. I logged in to my nook using my linux pc and followed the above directions. After the re-image you have to do a data reset by going in and restoring to factory settings in the nook itself.
As soon as I gave the reboot command it started the re-image as seen in this link:
https://lh3.googleusercontent.com/-p...2E_Restore.JPG
I'm sending you this message because I'm a "noob" and can't post in the developer forums. So if you wouldn't mind reposting for the others to use.

Was anybody else able to get to "Restoring Factory Image..." dialog?
It happened to me after 20+ resets, I was just searching for bricked N2E solution and kept on pressing the button... I would like to know how to replicate this again

i tried it with the 8 times boot failure method, it brings up the factroy reset screen, but it does not the reall factory reset, root and some other stuff were still n the nook after this "factory reset" don't know..
and don't tried (or even read) the method from the pm...
too busy at the moment :/

Inspired by rmkenney12 (and rev0l), I updated the uRamdisk file from TouchNooter 1.6.24 so that adb over wi-fi does not run at boot.
Disclaimer: Don't try this unless you know how to restore your nook in case it does not work.
To install the new uRamdisk:
Unzip the attached file somewhere, then...
Code:
adb connect <nook>
adb shell mkdir /cache/boot
adb shell mount -o rw -t vfat /dev/block/mmcblk0p1 /cache/boot
adb push <path>/uRamdisk /cache/boot
adb reboot
Cross your fingers and hope it works.
You will also want to download an app to turn adb on and off. Search market for 'wifi adb'.
P.S. Does anyone know specifically what needs to be changed in the uRamdisk to enable adb over usb?

This guide isn't working for me. It says that after you create a noogie sd card, just pop it in, start the nook and it will mount the 7 partitions....
What 7 partitions? They never show for me. When I start the nook with the card inside it mounts the "boot" partition which is 64.8 out of 74.7 megabytes.
That's it. That's all I see. Inside of this partition are the files that were contained in the noogie image.

which guide do you mean?
anyway, i don't know if windows can recognize all partitions...
download a live cd linux and try again

Ok... This is on windows 7. I dont know how to use Linux.
I am trying to root the Nook STR and using the guide provided here. It just gets stuck at the rooted forever screen, and the rest is as described in previous post.

How to disable carrier-check for native WiFi Tether (no root)

*EDIT* This appears to only be working for people with NON-unlimited data plans. I apologize for the inconvenience...
Saw this over in the AT&T subforum, originally posted by @ExTREmE99 , just reposting here.
This will disable the carrier check on your Verizon G4 and allow you to use the native WiFi tether - no root needed!
1. Enable developer mode (Go to Settings -> About phone, and click on the build number until the developer mode is enabled).
2. Enable USB debugging under Settings -> Developer options
3. Connect the device with a USB cable to a computer with the Android SDK platform tools installed
4. Start an adb shell: adb shell
5. In the adb shell, run these commands one by one:
settings put global tether_dun_required 0
settings put system tether_entitlement_check_state 0
reboot
When your phone comes back up you will have a fully functional native WiFi tether

don't use the hotspot app - in fact, disable that one.
You want to use the built in functionality to tether (not technically an app)
Go to settings, More (under wireless networks), then "Mobile Hotspot". You can setup your SSID and password in there. Also, you can create a shortcut in your notification bar by scrolling over to the right side, clicking edit, then checking the box next to "Mobile Hotspot"
Hope that helps.

Could you try disabling the verizon hotspot app? Mine was disabled way before I discovered this so I may need to add this step to the instructions. you may want to go through the steps one more time after that to ensure everything is set correctly. Don't forget to restart either. It works great on mine so it should for yours as well - unless you took the update a week ago?
Let me know - Thanks!

hmmm i think I'm confused. My Hotspot app is apparently still in my app drawer. When i click on it it just takes me to the native hotspot functionality.
Honestly I'd attempt to run those commands again. It would help if you took a screen shot of the command prompt window after running all of the commands. After each command it should pause for a second or two then jump to the next line with no errors or responses.
Is your USB debugging on? Also, are you in MTP or PTP USB mode when plugged into your PC?

Have not taken any OTA.

When I attempt to enable hotspot I am greeted with the "Use of this service requires a subscription..."
FoxFi seems to work, I just HATE having to change my lock screen in order to use the damn thing!
I'm willing to run further tests and commands if you would like, please just let me know.
I have NOT taken any over the air update. I used the Debloater tool and blocked/hid the app.

Here's a screenshot of my terminal window:
I'm using the native tethering just like everybody else (Settings, More, flick the tethering switch to On and receive the service check). Haven't taken the OTA and have the service disabled via debloater tool. I appreciate the help!

At this point I'm not sure why some are reporting that this works while others aren't. I added a message on the original post warning that this isn't a for sure thing. I'll be sure to update if/when I find a fix or what is going wrong, but for now I think I have enough info to look into this. thanks for your help everyone and I hope that I can find a fix for this. Worst case - we have to wait until we have root to enable this.

Rooted amazon fire tv booting to black screen.

Hello, today one of my rooted fire tv's became stuck on black screen and basically none of the important stuff can be accessed. This has happened to me a few times in the past and I am usually able to get the settings menu launched by playing around with the remote and the voice functions or if all else fails usually disconnecting my network will prompt the network connections menu which then will jog the main settings again and from there I can force quit and get it back up and running. But today I have gone through pretty much every method I know of and still no luck just a black screen. I run xposed on my fire tv so it is set to use spmc as the homescreen launcher. Any other methods out there that I have not tried? I wanted to avoid having to do a factory restore and reinstall everything if I can.

Nobody? LOl

If you just need to get into the settings menu, then connect to the Fire TV via ADB and run the following command to load up the settings menu:
Code:

If you just need to get into the settings menu, then connect to the Fire TV via ADB and run the following command to load up the settings menu:
Code:
adb shell am start -n com.amazon.tv.launcher/.ui.SettingsActivity

Is there anyway to access settings without abd. I know I can change resolution and restart from the remote is that all?

The only other way is to hold the home button until the popup menu appears with the settings option. You have to be on one of the newer software version for that to work since it was recently added.

[MOD]No notch ? Welcome to the immersive mode ! Remove the notification bar

Hi,
Our Xiaomi MI 9T is splendid with its great AMOLED full screen without any notch or hole.
However, the web browsers like Chrome (and others apps) doesn't propose the possibility in the settings to remove the notification bar and to get a true immersive full screen mode.
No problem, adb is there!
No need to root the smartphone.
EDIT: I have tested "Immersive Manager Application" from Google Play Store and it's perfect. Very simple and it works even when you reboot your phone.
No more need to type adb commands below except at least few adb commands to grant the Secure Settings permission to the app. This is well explained by the application when you launch it the first time.
I let the adb commands below for information in case we had some "purists" who prefer adb than an immersive app.
1/ Enable the Developper mode
Go to Parameters/ About the phone
Click many times (at least 10) on the MIUI Version to activate the Developper mode
2/ Enable USB Debugging
Go to Parameters/... Others parameters/Developper options
Click on USB debugging
Click on Install via USB => You will have to connect to your MI account
Click on USB debugging (security parameters)
3/ Launch adb on your PC
Get adb.exe on the net (very easy)
Put it in a folder of your PC (for instance C:/adb)
Connect your smartphone to the PC
Launch a DOS command window
Go to the adb folder => cd /adb
To check if your smartphone is ready, type:
Code:
adb devices
If it's the first time, there will be a popup on your smartphone to authorize the adb commands
Then, normally your device will appear after typing "adb devices"
4/ Get the list of applications installed on your smartphone
Code:
adb shell pm list packages
Retrieve the name of the application(s) you want to remove the notification bar.
5a/ For instance, hide the notification bar only for Chrome and Google Photos
Code:
adb shell settings put global policy_control immersive.status=com.android.chrome,com.google.android.apps.photos
Note: Each time you enter this command, you cancel the previous one. You need to type only one command with all the apps you want to remove the notification bar (names of app are separated by a comma ,).
5b/ For instance, if you want to hide the notification bar for all the applications
Code:
adb shell settings put global policy_control immersive.status=*
6/ If you want to cancel this setting and put back the notification bar
Code:
adb shell settings put global policy_control null*
Enjoy your brillant full screen mainly when you are in dark mode.
:good:

Pls the screen..

The setting is reset on reboots. How can it be persisted?

Do you have root permissions? If the asnwer is "yes" you can do this:
Install terminal emulator from google play store. Open it and writte "su"
now writte this:
settings put global policy_control immersive.status=*
Tachan! you have immensive mode active. Only save the command in a note app. Always you reboot your phone the only thing you have to do is open terminal, su and paste your command.
A lot more easy and fast than do it with adb. the only "problem" is you need root.
If someone knows how to add an exception, please say so.

How do you show it on lock screen? Any ideas?

Enable USB debugging (security settings) under developer options.
I used SystemUI Tuner as it allows for blacklisting apps (sucha as whatsapp) that don´t manage full screen well.

Thank you! It worked, but as stated above, it reset after phone restart.
Maybe running a tasker command at boot might fix it ?
Edit: Use the Immersive Manager app (thank me later!)

No, it's not necessary to unlock the bootloader.
You have just to activate the developper mode as I indicate it.

Yes, it's true. Each time you reboot the phone, you should loose the setting.
And good point, thank you Ramsyst, I didn't check on Google Play Store the myriad of immersive mode applications!!
I have tested "Immersive Manager Application" and it's perfect. Very simple and it works even when you reboot your phone. :good::good:
I had previously created a task with Tasker and AutoTools (paid version) to change the immersive mode with the "Custom Setting" feature. But knowing that there are many apps (free and paid version) doing that better than AutoTools, it's not usefull to describe how I did it.

With Tasker you already have an option to make all apps you want to go immersive! There is no need to use any other command or app.
I believe everybody in the world should buy tasker
Is the best Android app. It may looks hard in the begining, but your imagination is the limit to do whatever you want.

Hi how can i used this on split screen but in full screen mode with status bar and navigation?

You're right. I had never tested the split screen function. The notification bar is not hidden on split screen mode even when immersive mode is activated. The result is a bit weird as there is a mix of notification bar and app on the top of the screen.
"Google search" indicates that you are not the first one to face this issue... but apparently no solution has been found so far.
If somebody can help.

Broken display. How to unlock the smartphone and recover the data?

Hello everyone,
I would like to recover the data from my Xiaomi Mi 9 SE (stock and non-rooted OS), including photos, videos, and email accounts. However, the display is completely broken (it does not display anything) and I cannot access the internal memory through ADB because I cannot unlock the display. Is there a way to unlock it via ADB or other software? In the worst case, can I buy a cheap display (not the original one because it costs about 200 euros) and connect it to the smartphone mainboard? I don't know if there are differences among display connectors or they use a specific standard.
Thanks in advance for any suggestions!

Try using a Usb-C to HDMI adapter to connect it to a Display. But then you need to connect a mouse...maybe there is a single to connect 2 usb devices.I'm not sure

You may try (if you didn't already) to enter unlock pin/password via ADB - didn't test, not sure if it works on MIUI:

The following works for me to unlock the screen by ADB, but:
- ADB must be already enabled on the phone
- PC you are using must be already granted ADB
- Phone must be rooted
- ADB must be already granted root access
(Otherwise e.g. Magisk pops up to grant root-access to ADB but screen is still locked and you cannot confirm)
First, verify ADB, enter the shell and su mode
Code:
adb wait-for-device devices
adb shell
su
At this point press Power button (if screen is ok, it would light up).
By the first command you swipe the screen (if screen is ok, you would see popup to enter the unlock pin/pass)
By the second command you enter your unlock pin/password
Code:
input touchscreen swipe 930 880 930 380
input text <your-screen-unlock-pin-password>
At the end, exit su and shell:
Code:
exit
exit
So, I have two SIM cards (both locked by pin) and lock screen (all the same).
Keyevent 66 means Ok.
The following worked for me to unlock the phone on reboot:
Code:
adb wait-for-device devices
adb shell
su
input text 1234
input keyevent 66
input text 1234
input keyevent 66
input touchscreen swipe 930 880 930 380
input text 1234
exit
exit

Btw, I just tested on my unrooted Huawei Mate 9 (EMUI 9.1, Android 9) and it works without root, hence without su command
But on Xiaomi (mine is Mi 9T with MIUI 11, Android 10) it requires root and su command
You may try without su command on your Mi 9SE, but probably it won't work without the root and that su command

I'm having the same problem, broken screen and no image, everything else is fine. But I have unlocked bootloader.
Just delivered an adapter type-c to hdmi+usb, so I can connect to a display and use a mouse. I'll give it a try
