Is there a way to add other dictionaries to Nook Touch WITHOUT it being rooted? I know that some people managed to add hyphenation rules for other languages without rooting while these rules are a dictionary actually.
Modifying your NST without permanently "rooting" it is possible, but requires the use of a custom boot image, either just for temporary adb access so you can do your modifications manually or you can use it to run a set of scripts to carry out the modifications automatically.
The latter is what I use in nookRestore which is simply based on the original 1.0.0 boot image that I extracted from my own NST.
But if you don't know u-boot, how to modify init.rc or write your own shell scripts, then no, there's no way that I know of to do what you're asking without rooting it first
Have found one custom image with dicts, will try it later.

Can you give us more information about this custom image?
If you can read russian here is the post with "no root" images. http://4pda.ru/forum/index.php?showtopic=253792&st=400#entry9306857
If not, I might translate it. I use "mini04" image.

Hi just asking if anyone knows any links or archives or anything i can read through, im looking to build my own ROM. any help would be much appreciated and dont mind donating to someone that can help me start to learn.
Thanks
Well, first of all you need to be able to compile Android. This is pretty easy and it's explained directly in the developers google website. If you're not running a Nexus One or a Nexus S, you can't actually compile a working android copy for your own phone "as is" from AOSP. Because of this, you firstly need to change / create some dirs and files in order to add the support for your particular device. I'd start searching on CM repositories for this (I've got the Nexus One and thus I don't have such problems).
After you've compiled Android for your device and your changes (for example root), you'll have some disk images (you can find them all under out/target/product/PHONE_MODEL/, they are the .img files). You can directly flash them via fastboot ("fastboot flash boot boot.img" etc.). You can though create an update.zip file, and this can be made extracting the system.img file in a folder. Remember that you'll have to recreate the symlinks (to toolbox and/or busybox if you want to include it in your build) and set permissions, as zip doesn't save the permissions of the files once compressed.
Thus so far, if you succeed making every single step you should have your ROM on your phone
If this is the wrong thread I'm sorry and mods please move it.
My nook is currently rooted...
I have tried all the 3rd party e-readers different launchers.
I'm really over the idea of being rooted with the exception of "Current book cover screensaver + custom shutdown image" hack and possibly resizing my partitions.
Is it possible to replace the Uramdisk with one that had adb enabled and then just manually push over the modded files?
or am i going to need to install busybox, su, and superuser.apk?
I would like to keep it as close to original firmware as possible...
Can anyone shed some light on this?
Ok so i'm guessing busybox is required to be able to run the Current Book Cover Screensaver.
1st i turned on adb wireless.. installed the files per the instructions over ADB
rebooted and I was stuck in a boot loop
2nd restored to a fresh firmware.
Installed adb wireless, superuser, su, and busybox.
Then installed the files per the instructions over ADB
rebooted and everything works great.
Now i just wonder if i can uninstall Superuser or busybox...

hi,
while i'm not totally sure, i suppose you can definitely uninstall both superuser and busybox.
In any case, the modified ramdisk with ADB enabled (either WiFi or USB) is enough to allow you to push/pull files to Nook, and to open a shell (as root).
Busybox is just convenient if you plan to use shell sessions since it includes commands like cp to copy files, and others, but you can live without it (using ADB push to copy files, or using command dd, for instance).
Superuser, if you refer to android application (APK) it's just used by all other applications requiring root privileges (like RootExplorer, for instance), but if you don't plan to use them, then it's not needed.
In any case, you have practically my same configuration (as close as possible as stock firmware): after all, i use Nook just to read books, so don't need custom launcher and google apps! I would just mention XorZone modification that is really useful for me, since it's can act as a sort of launcher, and can deal with useful features like button remapping. The only other application i have installed is this PDF reader, since the stock one is really poor, while this one has a better zoom management, and also has specific features for e-ink devices and expecially for the Nook (like partial refresh).
Of course, to install the applications, i just use ADB.

Ok so something must have gone wrong when I installed your screen saver mod if i was stuck in a boot loop. Because I assuming you have it installed on yours with out superuser, and busybox... i just i can just install them now and then it should still work.
I also just use the nook to read EPUB book, i have a very nice android tablet that i use for anything and everything else. I would much rather have a high battery life on the nook then bells and whistles i don't ever use.
If you're running linux or have access to a linux box, you could just grab noogie and it should show all partitions. With this you could make the changes without ever having to touch the uRamdisk or ADB or needlessly installing anything to actually root the device.
As it is if you were to try this your way you'd have to first root it using like Minimal Nooter or TouchNooter then remove everything you don't want afterwards (su/superuser/busybox/gapps/etc).
Personally what I did was I installed touchnooter and because I like my devices to appear stock I left all the buttons unmodified while leaving a very faint button savior icon on one side that'll allow me access to android launcher the app drawer etc. This way I can use it like a proper android device without having it appear as anything more than a basic reader.

Hmm interesting...
What i did was i restored to stock... so my nook was completely unrooted...
Switched the uRamdisk using noogie then ADB the following files over and set the permission...
android.policy.jar [needed only for "current book cover screensaver"];
services.jar [needed only for "current book cover screensaver"];
Settings.apk [needed only for "current book cover screensaver"];
framework.jar [needed only for "custom shutdown image"];
What your saying is just use noogie and linux to replace the files and set the permissions.
I plan on Dual Booting my G-Tablet with linux so i can resize the partitions on the nook, I'm going to try your suggestion and see how it goes..
Forgive me if I have a gross misunderstanding about the hardware in the NST, but in my eyes it should be possible for the Nook to sleep but retain the screen, perhaps with a small banner indicating it's in sleep state and you need to press the 'n' to wake. It just seems silly having the benefit of an e-ink display only for the screensaver to kick it when it sleeps. If it didn't do this, I could (for example) leave a map open in OsmAnd and refer to it still while the Nook is sleeping. The only 'solutions' to this I've found involved plain and simply keeping the Nook awake! A hack I can think of would be to somehow bodge something together to take a screenshot just before the nook sleeps and set it as the screensaver image. Seems silly though... I've had a search around and can't find anything related to this specifically, more either people wanting to keep the nook awake or disable the slide to unlock.
Any thoughts welcome!
I had the exact same thought,
so I'm making an app that takes a screenshot every 1:50 minutes and saves it at a screensaver,
to be displayed when the nook goes to sleep.
hopefully it will be ready this weekend so stay tuned
It should be be simple enough.
Modify /system/framework/android.policy.jar
The class is com.android.internal.policy.impl.LockScreen
What puts up the "screensaver" is updateBackgroundImage()
The layout is in /system/framework/framework-res.apk,
res/layout/keyguard_screen_gossamer_unlock.xml
I'm not sure if changing the layout to transparent and not updating the image should be enough.

Oh I wish you would have said that two days ago...
It seems a far better solution than my app, maybe I'll try playing with that later.
I tried replacing updateBackgroundImage()
with a stub, but the screensaver still comes up as usual,
Only difference is the "slide to unlock" screen now has black background, so that's what this function is doing.
Time for plan B (or C, really):
If I were to modify framework-res.apk as you suggest, Will I need to resign the whole system, as here?
Update -
The function that sets the screensaver is createScreensaver(), in class com.android.server.PowerManagerService, found in /system/framework/services.jar
I modified it to make the screensaver invisible, but unfortunately it also means there's no indication that the nook sleeps.
Anyway, it's better than constantly taking screenshots, so I'll stick with that.

How did you do that? I'm using the screenshot sreensaver app for that and I find it very useful. But the above mentioned way seems to be less power consuming. Could you explain it for somebody with very little knowledge about manipulating apk, though I know how to manipulate apk with xdaAutotool.
I don't know xdaAutotool, I use apktool but you can probably use whatever tool you like.
First you need a patched /system/framework/services.jar
the one I attached here is for firmware 1.2.1 rooted with NookManager, so it also includes the NookManager patches.
if this is your setup as well, skip to 4
if you run a different firmware or don't want the NookManager patches you will need to patch it yourself
patching /system/framework/services.jar - some vauge instructions:
you will need apktool (or XdaAutotool or whatever) and the android-sdk.
1) use apktool to decompile services.jar
2) modify createScreensaver() in file smali/com/android/server/PowerManagerService.smali according to the attached patch-services.txt
notice - this patch is for firmware 1.2.1 with NookManager patches, it might not be ready for use with other versions - not only the line numbers, also the register v6 might not be a good choice if it is used later in the code without being assigned a new value first.
3) recompile with apktool.
replacing services.jar with patched version - complete instructions:
4) making a full backup before messing with the system is good practice, although the nook is notoriously hard to brick.
you could use NookManager to do the backup.
5) connect to your device with adb
6) apply these commands:
Code:
adb push pathced-services.jar /media
adb shell stop
adb shell mount -o remount,rw /dev/block/mmcblk0p5 /system
adb shell cp /system/framework/services.jar /system/framework/services.jar.backup
adb shell cp /media/pathced-services.jar /system/framework/services.jar
adb shell chmod 644 /system/framework/services.jar
adb shell reboot
7) relax, first boot takes a few minutes, this is normal.
with this patch the screensaver is invisible, so there is no indication at all that the device is asleep.
also, there's no magic button to change behavior - if you want to the screensaver back you need to replace services.jar with original version
Thanks for that extensive description. I'll try the next days to implement it in my system which differs from yours, since I'm using the custom rom from pinguy1982.
Got it.
I compared your PowerManagerService.smali with the one in my services.jar and made the changes.
Recompiled the services.jar.
Exchanged the original classes.dex with the new compiled classes.dex in 7zip.
Signed the jar file.
Had a lot of problems with adb, which didn't recognize my device.
Lost my temper, packed it into a ZIP-file and replaced it via CWM.
Everything is working now. Thanks!

Here you are:
Patch (nivieru's method) via ZIP, tested only with modded ROM from pinguy1982 and installed Nooter-Part1.zip. Install via CWM, to be safe make a backup before you do the patch.
Services-org.zip=original services.jar

Hi everyone!
I've patched the jar and now enjoy the last image in sleep mode. But, I'd like to wake app the Nook every few hours, update the page in dolphin and go back sleep. Page in dolphin has a meta refresh. But I can't wake up the Nook on interval. Is it impossible or I missing smth very important on this topic?
If anybody has some experience on topic, please comment.
Update, my solution:
Re-signed the system with personal cert and implemented an app instead of dolphin+web page.
App wakes up every few hours, updates view and throws device to deep sleep. Hope to get an uptime up to 10-15 days.

I've done exactly as described in points 4-7 on NST firmware 1.2.1 , rooted with Nook Manager.
I used Root explorer for replacement and rename of patched-services.jar.
After rebooting of NST, it works as intended - the screensaver is unseen, but it appears other problem.
When i click at random .apk, nothing happens, only the screen is flickering once and that's all.
I cannot install apk-s, nor uninstall them....? WTF ?
Someone with explanation...?

Replacing services.jar while the android system is running can cause problems, that's why I suggest doing it through adb after issuing the "stop" command, which stops android while leaving the underlying linux (with adb) running.
You should try that and see if it helps.
I will try, but before that another question from me.
Is there a chance the file "patched-services.jar" to be remade as .zip file and installed thru CWM.
If this can be done, i will be glad somebody to share the .zip file, because i think it is more comfortable for installation than using adb shell....
thanks
P.S. Adb don't work correctly for me, so the only available option is obviously flashable .zip file...

Has anyone tried this with FW 1.2.2 yet?

If the original services.jar was patched, it will break NTMM since that relies on patches. But if you can discern what the additional patches are you could patch the 1.2.2 file used in NookManager.
Edit: but if you just want to see how it might work, you can probably use the 1.2.1 jar without any problems. When I first started working on the update to NookManager I used the original 1.2.0 jars that were provided with FW 1.2.2 and saw no evidence of problems. A diff showed very minor changes. Depending on how extensive the patching is for this mod, it might be easier--if you still want the use of NTMM--to patch the file in post #8 for NTMM since the patches are well documented on github. Otherwise you have a lot of diffs to look at and sort out.
Hey guys! This my first post on XDA, I'm a new member. I'm fluent with scripting and general OS. I hear often the phrase of a dirty flash, which I'm understanding to be flashing a new ROM without wiping the system first. I assume that may include not wiping the data partition as well. It's my understanding that is accomplished by editing the updater script within the ROM to be flashed. I understand that can easily be accomplished by unzipping file, making edits and then zipping back up. It's my understanding that can be accomplished without unzipping the entire ROM, by editing the contents in place using a PC and even with some native Android apps. relative to Android app that does one that does that extremely well, I'd appreciate that feedback is one point of this post. What I'm looking for is a way to zip the existing flash file into a new flashable ROM with a pre-built script that in essence calls the previous lines of the script and executes the code sequentially, while watching for the "delete" entries for partition like system or data and avoid executing those lines of code. My main purpose would be to avoid having to save two copies of a ROM on my sd card, one that wipes and one that doesn't, for purposes of space. Additional info. I'm currently using safestrap on a Samsung, I am not asking about aroma or a kitchen solution as they are not compatible but standard update.zip scripting type code. this seems easy with standard shell commands, but I must move out how that would relate back to the update.zip commands available. it may not be possible, and/or there may be a simpler solution I have not heard of otherwise. What is the standard practice for other people wanting to do a dirty flash on a ROM that they've downloaded that white partitions by default?
Hi everyone. I'm scratching my head here and struggling to find a solution that doesn't require root.
I've got a hosts file that I love as it blocks nearly all advert servers on my phone.
I know there are several adblocking apps but they all require root.
I have had to remove root as I have some critical apps that still don;t work, even after hiding magisk from the apps within the Magisk Manager.
I've got a magisk patched image that I can "fastboot boot" with and can edit the hosts file (after remounting /system as rw) but when I then reboot afterwards, the hosts file has been overwritten.
Can anyone help me please or give me a pointer of how to make the hosts edits remain following a reboot?

You can't without root even if you do it your system partition will be modified and it will result in phone not booting or just safetynet won't pass.

Interesting idea regarding spoof VPN.
Do you know how the hosts file is generated? If it's copied over from somewhere during boot then could I edit the source file it's copied from?
If it's generated procedurally, might I be able to script it to add my edits during creation?

System partition ? so that's a good idea but you'll have to compile a rom to change this file. On Linux distro the host file is a thing you can modify easily. On android it's just deprecated by google as it's use mostly used as an adfilter. And google is an ad company. That's my guess.
Anyway host file will always need root even on Linux.
Simply because it can be used against you.
The problem is more on apps that blocks you because you're rooted than being rooted for changing this file.
If any app could modify host then bang you go to YouTube and it redirect you to something else.
Maybe for you it's just an adblock file but it's a little more than that.
So sorry but it's root or vpn.

So? Could I possibly extract the system.img from the stock ROM, make the edits there and then recompile?
(I've got a copy of payload.bin that I extracted a few weeks ago, when trying to flash the August security patches (this was before I did a compete flash of stock ROM using fastboot)
That actually seems like it wouldn't take too much effort

Ok I understand.
How does the device 'know' that the system partition is corrupt? Does it perform a hash check perhaps?
How would compiling my own custom ROM avoid this same problem?

Search "dm-verity" and "safetynet". The first one is what will look at any r/o partition like system and kernel. It's been a long time since i dig into this. I'm not into this anymore.
But You can disable it but you'll loose safetynet, encrypted partition etc... (i may be wrong but you got the idea). And safetynet look if partition have been modified and you are a certified device if it won't pass the banking app and apps like Pokemon go etc won't work.
Magisk hide the fact that the kernel img have been touch and most app that detect it detect just the app itself. That means magisk capability (su, hide and module)
So you could maybe compile stock rom with a custom host file. Never touch vendor partition! Make a backup before! By booting and not flashing twrp. Do not flash twrp just use the "fastboot boot command"
You'll need to make a custom kernel and system img to flash in order to do it.
I'll try to do a rom without anything modded except kernel without dm verity and system with your host and i guess it needs change too.
I dunno if it will pass safetynet after.
Just don't brick your phone ?
Keep in mind that you'll loose ota. There's a chance that the rom work with just some changes but i can be a mess to do.
Why not trying a custom rom like lineage os?
Using their supersu zip won't you be able to replace the host file then remove root?
Once you make a backup a move it to a pc as a savestate. You are free to try different solution
