Hello,
Last night, I tried to modify the Screen DPI on my tablet ASD Digital MID 162... After the device restart, splash screen not ending... I reset my build.prop to the default value, and make a wipe cache with Adb and instead of write wipe /cache, I write wipe only... And my device don't boot and I can't use adb shell... The error is : "Permission denied (13)"
Someonee can help me ? Please ><
(Sorry for my bad english, I'm french)
How did you modify the DPI exactly?
Through an app?
Editing the build.prop?
Laughing at you while eating Jellybeans
Sounds like a messed up build prop and the device is bricked..
Yes I've modify the DPI in build.prop file...
What can I do for repair the boot ?
One help ?
Gonna have to reflash. You pretty much wiped your device so you will need to reinstall the os
Wayne Tech S-III
I know that, I have to reinstall the OS.. But I don't have recovery mod on my tablet... The only one I have it's an recovery stock (I think, I'm not sure).. I can do "adb ls/", "adb pull and push" , that's all... One idea ?
[I've tried to push a shell in /system/bin in recovery mode, but I've got a error (permission denied), I want to push a shell for execute "flash_image" tools with an new OS .img file for solve the problem ]
I've had similar problems with my myTouch when I've done things it didn't like. Providing that you can boot to the stock recovery that gives you the options to reboot or apply update then your almost saved. Because if that's the case then ya can
copy the custom recovery.zip file over to the root of your sdcard (I used a computer for that as when I killed my phone it wouldn't boot past sock recovery or boot-looping)
rename it to update.zip then boot into stock recovery,
apply the update from sd and your device should, hopefully, temporarily start the custom recovery so that you can
wipe re-flash or restore from backup.
This all assumes that your device has a way for you to access the sdcard without your device.
Hope this helps/use at your own risk

I go to make a meditation on this idea... The problem is that I can't do anythings with the "stock recovery", It's just a screen with an open [dead] droid with red exclamation mark, and that's all. Nothing to do when I push one touch like Volume - or +, but when I boot with another key as Power Up, A black screen appeared, and it's all... (I want to show a photo with a screenshot, but I'm a new user, I can't :'( , I've no luck !!!! >< )

That is not recovery that is the kernel panic screen. Only option is an Odin install of stock

Ok so I read the post about kernel panic screen and agree mostly, however, I've seen the panic screen and gotten past it with a combo of volume + and power button at the same time, it then returns an error message on how recovery wasn't able to be read from its expected source, it then blanks out for a moment and boots the stock recovery, from there I apply the update.zip that I renamed and placed there with a computer, and then everything is good again.
Note: I don't have the specific device you do, or know the method that you usually used to use to boot into recovery.
Usually, its a combo of two or three buttons like on my htc product it's volume up and power button and on my Samsung its volume down and power and camera button. Note: when I do actually get into a custom recovery on my htc the power button then changes to turning the screen off and on instead of selecting things, which made it a hair pulling experience until I figured out that the directional pad on my device was the select button. (Moral of the story, power button sometimes controls the power to the screen, sometimes its used for selecting things, odd but be persistent and try combos because I thought my phone was killed till I hit the power button a second time and the screen came right back on.)
Odin should resolve the issue though for sure if fiddling around with your devices' buttons get to be frustrating, I just figure that any time I touch a computer to re-root my phone I've not done enough trouble shooting.
One other thing you can try is a targeted google search
Eg: 'solved [device name] [issue with device] site:[address of site to search]
So for example when I had a problem with my Samsung I used
'Solved epic 4g bootloop site:xda
Note I had to shorten the site as I'm not allowed just yet to post links but you'll want to include the .com
You can also replace the site: with similar: to search sites that are like xda with similar results.
What's the name and manufacture of your device? I'll see what I can dig up for you.

Good ! Thank's youuuuu !! I've can access recovery mod with combo of Volume + and Power... My device is "ASD Digital 162"... Tonight, I go to make an update.zip with an android OS img file... Thank's !!
Where I can find an image file of my Rom ?
This device don't have many popularity on google, and he have no constructor website... Where can I find a ROM or Custom Rom ?
For information, I've one another tablet (Exactely same device) arround of me.. Can I extract the ROM or a backup that could me restore the Android OS ? I don't want do stupid things with the other tablet also like I do this time...
(I want to precise... On my SdCard, a folder named "nandroid" has apparead , he content kernel file, system .img file, cache .img file, etc etc.., if you have any suggest on what can I do with it )

You could try it, though I wouldn't as internal hardware can differ inside identical devices, you could end up 'super' bricking your device which I don't think is a real term it just sounds less scary than 'muten' bricking. The phonomonon can be observed when someone flashes an epic 4g touch rom on to an epic 4g and things are never the same. Not saying that's the case just my perinoa speeking up here.
Actually I think there are guides floting around on how to make and scrub your own custom rom, maybe you could do a full copy of the working device though the usb debug bridge, scrub the user data and dependencies from the copy and push it to the not-yet working device... or you could blase the path allready well troden.

now when you're going to your sd card are you talking removable sd or internal?
Some devices don't have an external or its inaccessible,
other devices make it confusing by also having a partition on the internall memory labled sdcard which looks a lot like the sd card that can be un mounted and re mounted (I believe it to be confusing because the sdcard is also lables sdcard),
And yet others are really easy to spot because its the only thing labled and removeable as an sdcard
Any who if your talking about viewing your sdcard with prisice then likely what your viewing is the old contents of the card (what ever you had on it before this learning experieance snuck up on you) and I would treat it like pizza from last night's party. Meaning that the backed up apps could be used and there could very well be a good backup in there if you made one in the before time, but I wouldn't force my device to choke down leftovers when I could start anew.

You're Welcome; knew you weren't out of options.
Make sure to reroot from the start of what ever guide you used (as a gard against myself and the decisions I make I always keep my costom recovery flash zip for all my devices in the root of my sdcard and labled as update.zip or whatever the manufacture's recovery software by defaults to looking for. That way I can always reinstall if the device still turns on.) as you'll likely want to flash and mod with furver, I know I always do, keep a clear head and it should all work out.

Yeah just spent the last hour or so looking for asd mid 162 tablet in google, tried a few modifide search quaries, and such to no avail. Saw your question on a few other boards too. I've a feeling that you've run into the same problem with low popularity and lack of documentation. If you got any other discripters I can use for searching I'll be back on the case after work today

On recovery screen, is marked "SDK : MID-A13-Android4.2-V1.0-20130121"...
This tablet is the 9' inch model of ASD Digital 142...
Looks like that's the rom, could try flashing it again, just google the 'a13 9 inch tablet' and you'll find info on allwinner.
Happen to know what the ASD stands for? All I'm getting is autism results. (Which putting the word autism in this thread and adding '[minus sine]autism' might help)

I don't understand what you say... :/
Can you use easiest word or terms ? (If possible)
Sorry about that.
The first part of last post was discribing a search quary I used to find info on the rom you may be using. Looks like a cross platform compatible rom on the face of it but I'm still looking into it.
The second part of last post was stating that when I search for your devices' model 'asd digital' I'm getting results for human medical problems and not hardware related information. So I put the main word that was triggering that into this thread so that I can then search 'asd digital -autizem' and cut those results automaticly from the google search results.
Still working on this with you, just have split atention with trying to finish my first guide for android/linux dulebooting (unrelated to the issuess that curently plage you but still may be worth a look at when you've a system up and running again.)
At this point doing a restore from a working device's backup like you where saying might be the best bet on reviving the simi-bricked device, but I'll have to do some more reading before I really feel comfortible sugesting that you go though all that.
Now that you where able to boot a recovery screen; have you tried anything to get it back up and running? Such as restoring from a backup created after rooting the first time around?

I just currently opened my box fresh out and installed z4root to root it... Sucess!
Now im trying to downgrade as i am "supposed" to according to this thread.
http://forum.xda-developers.com/showthread.php?t=1036956
This is what is in my about screen under settings so you know what version ect i have http://img546.imageshack.us/img546/1476/20110427032325.jpg
from the aforementioned thread i downloaded the 4349_Downgrade.zip and placed it on my sd card... Renamed it update.zip and closed usb connection, and then powered off and powered up first pressing and holding the "+" on the volume rocker on the top of the tab. and then pressing power.. When i say "+" i mean Volume + witch is on the top left of the tab closest to the right in the direction of the search home menu and back keys...
When im holding this combo of buttons the screen boots up after a second or two says recovery key detected or whatever in the top left for a few seconds and then goes to the g tablet white screen... THen it shows a box with a downarrow on it and a progress bar for a few moments and then shuts off and reboots into the homescreen.......
I read in this forum a topic how the guy experienced the same results but turned out he was holding the Volume - key... I made certian i wasent doing what he did and literally just held the Volume + key on the right edge with the tip of my nail and held power... Same results..
I have tried with the program root explorer going into the file manager... (Why is there a file called sdcard2?? never seen that before) i go into /sdcard find the update.zip i put from the renamed 4349 file and then back up to the "/" dir and mount as r/w and paste the update.zip in there then mount as r/o back out to home power off.. i repeate the aforementioned process and still the excat same thing...
The origonal update that was put on there when i first put in my newly formated fat32 sd card i deleted.. i have searched and search and have no idea what is wrong or how to fix this... Certianly i couldnt be the only one with this issue?
Please help, im just killing time sitting here waiting for help lol.... Thanks..
My end result is im trying to get CWM 08 on there and a great and stable rom witch i choose that RC1 of vegan.. Unless u know of a better one. And once this is all done is there a good kernal i should be flashing? Why and how do i do it.?
Thank you in advance..
1) The downgrade is only necessary if you were on 4349 to begin with.
2) what you described is exactly what should happen in stock recovery for 3588 and older.
3) No... it is not exactly what others have said about holding the wrong volume key because when you do hold the wrong one the screen goes black after a few seconds.
4) SDCARD is your internal storage. SDCARD2 is the mount point for your external (MicroSD Card) storage.
5) It sounds like nothing is wrong...
6) Install CWM... http://forum.xda-developers.com/showthread.php?t=865245
Ooook
The thread i mentioned in my first post the first link if u click it the title of tje topic reads
[STICKY] [ATTENTION] - 3991 and 4349+ VIEWSONIC-LOCKED BOOTLOADER INFO here
Also it has a link to a pic of my about phone so cant u tell from that?
I am lost i did excatly to a T as described in the tutorial in step 6 in your reply and im getting the same thing i hold down volume + it says recovery key detected for a few secs in goes to gtablet screen and flashes to that down with a down arrow.....
What am i missing? Surely i dont have the only tablet with this problem..
Yes, I can... Your TAP UI version is 3391... LOWER than what you are trying to downgrade to. So you don't need to. You are seeing exactly what is supposed to happen with the version you have. This is the normal behavior for that version.
The only thing you are missing is the knowledge that nothing is wrong...

From what i gather from that link is that i am to take the files insides cwmod_microsd.zip witch are update.zip and recovery folder that houses command and physically take the microsd card out and mount on my computer witch is technicly SDCARD2 and place those files in that root directly... and then the power down insert card and vol up and power.....
I am getting the same issue same box and same nothing.
Most likely because you aren't following the directions. Take some time to learn at least the basics about your tablet. Then read the instructions again.
you can do it on either the internal or external. It depends on what the line in the command file says. Once you boot once whether sucessful or not the command file is deleted. Your making this harder than it is
Then what am i missing? I got this tablet yesterday at 2 pm and stayed up till 3 am trying to get CWM on it!
I cant imagine what im missing, ive read dozens of posts tried atleast 15 times putting either the downgrade or cwm sdcard update files in the internet "/" or "/sdcard" or "/sdcard2"
And yes i noticed that it deletes the update and recovery folder if i drop it in /sdcard2 or "/", ill put the files there either directly to sd card from the computer or thru root explorer and when i hit vol + and power it does the same thing.
This has to be the most frustrating tablet/ android device ever!
The last time i had something this hard was when i bricked my iphone in early 09 and figured out i had to reload the ipw file via a brand new install of itunes from a virgin computer (that computer turned out to be me using the librarys lol)
so i just got both the internal and external cwm files from this post
http://forum.xda-developers.com/showthread.php?t=865245
and put them in both /sdcard and /sdcard 2 for some reason when i used root explorer i noticed that for somereason in /sdcard2 there was a recovery/recovery/command so i pulles recovery to /sdcard2/recovery and pasted it there and deleted the other recovery folder.. re did the whole process and low and behold i was lookin at a CWMN screen! so... i have no idea, but if i ever meet the man who created the Vewsonic g tab ill kick him in the nuts.
Now i followed this guide
http://forum.xda-developers.com/showthread.php?t=865245
and i mounted the usb put the Vegan Rc1 rom in the ROMS folder and choose zip from sd and installed... and im just stuck at the view sonic screen, so i powered off did a wipe data factory reset and wipe cache and then went to advanced and fix permissions... Then to choose install from sd card choose my vegan rom and installed then backed out to home and hit restart and again its been ten mins or so and im still staring at a viewsoniv screen still..... Is this normal or any more suggestions?
There is a fix but as much trouble as you had installing clockwork I'm suggesting you avoid that fix so I'm not even saying the name. Stick with froyo roms
Thats not very helpfull... Just please tell me what it is i can ifgure it out on my own, i obviously did with the CWM now i just cant get the rom installed for some reason i have a tablet that just boots to the view sonic screen at the moment
Just to update...
I fixed it. THanks for your help and no thanks for your sarcasim.
Was stuck at the viewsonic birds screen
So i did so more, searching... its now 5 am and figured out what nvflash is and
via this thread http://forum.xda-developers.com/showthread.php?t=861950
and making sure u extract EVERYTHING in all the zip files with the exception to the USB folder u drop in the nvflash folder as directed, because if u dont u will get a error when u run nvflash_gtablet.bat
Once that is complete follow this thread
http://forum.xda-developers.com/showthread.php?t=865245
Word for word to install Vegan from stock... It may save a lot of confusion to just nvflash from stock and then drop the CWM recovery and update on the sd card and go that route..

With a bootable SD card are you able to.use ADB? If you are you might be able to push a normal build.prop to /system and be able to boot back into your rom. If not then like old fart said you may have messed up your partitions.

assuming you have adb setup correctly the commands aren't too difficult. i believe the following should suffice. i only know windows commands so yeah..
open your start menu, type in cmd and then enter.
navigate to directory where you have adb installed. in my case it was -> cd C:/ntroot
then connect your NT to your computer, make sure usb debugging is enabled which it most likely is if you can get into cwm.
use adb devices, and there should a string of numbers which is your serial number. if you see it then that is a good sign.
then adb remount, which makes the file system writable.
next make sure you have the normal build.prop in that directory that you have adb installed in.
then do adb push build.prop /system
should be very quick, if all goes well you should be able to boot back into your rom. otherwise, your partitions are likely screwed up...
if your partitions are screwed up, there should be a couple of links in the android development section that tell you how to repartition so you can start anew.
good luck.
When I connect to adb I get 0000000000 as my serial does this make since can anyone point me to a link to re do partitions I will look around also
but it is just easier if some one can point me to the right area

So I have bricked my Nook dozens of time but when I do I just download the acclaim_update.zip from one of these threads and go to a file in it.
Go to /META-INF/com/google/android/updater-script and then I just edit the first two lines. Edit both parts where it says "blaze" and change it to "acclaim". If you're on ubuntu then all you have to do is press saveand it will ask if you want to update the file (or something like that) and click yes. Then just make a CWM bootable sd card and flash that file Hope it helps!
I WANT TO START OFF BY SAYING THAT THIS IS THE FIRST TIME I HAVE MADE A THREAD ON THIS SITE.

The tablet that I am dealing with is a "Cruz Velocity Mini Tablet" running android 2.0 and no means of installing apk's.
Currently this is the situation:
A friend of mine lent me her Chinese reader tablet.
I told her that I could probably flash a newer version of Android on it, thinking that I could finally try my hand at making a ROM because I know for a fact that there aren't many ROMs if any at all out there for a chinese off brand reader like this.
After rooting the tablet I deleted the pre installed bloatware via ADB commands (shell) including a file manager (Astro) that I believe was the only way that you could browse files on the tablet, as well as some other pre installed applications that must have been necessary in retrospect. There is no existing vending capability or market application.
I am looking to make a custom ROM (Using android Kitchen and Cywign) through following this tutorial by lokeshsaini94 yet I feel like following that tutorial won't even get me where I need to be.
Click to expand...
Click to collapse
Things that I have tried at this point include:
Attempting to connect the tablet to my computer with the SD inserted (with and without debugging turned on) [Failed to show up on my computer as a device or anything]
Downloading the APK that I need from a file sharing website [Downloads fail]
Uploading the APK that I need to my Google drive and downloading it from the tablet [Says waiting for data connection and doesn't download even though connected to our WiFi]
Inserting the SD card into my computer, copying the APK I need over to it, then inserting the SD card back into the tablet, going into the browser and typing "File:///sdcard/<name here>.apk" to install an APK but getting an error in the installer after pushing 'install' -> 'Application not installed'
Trying to perform a factory reset; this simply makes the tablet reboot with everything the same as it was before.
Essentially guys and gals, my tablet here is running Android 2.0, I want to update it by making my own rom for it to something at least >4.0, and it seems that I've made things worse and have no way out of this mess. I think I've essentially bricked it even though it still works. :silly:
What do I need to do to make a custom ROM let alone flash/wipe this tablet?
All help will be incredibly valuable
There should be plenty of info here http://www.slatedroid.com/forum/93-velocity-micro-cruz-reader/ to get you on the right track. Not likely you'd be able to get anything beyond Gingerbread on there running due to lack of source code. Your only hope would be to see if there is a newer tablet with the same chipset that has something newer on it to port over.
Still no paddles

Thank you very much for your response. It looks like on that website I've already found multiple useful roms!
In fact I already downloaded one and put it onto the SD card. Apparently for these tablets you're supposed to, while powered off, turn it back on by holding the power button and the volume up button but all this seems to do as a whole load of nothing.
I fear that what I've done to it by deleting potentially sensitive programs previously, I have somehow managed to make this process impossible.
Is there some kind of way that I can plug this tablet into my computer and be able to completely wipe it so I can, at the very least, have a functional tablet that will work at all? I've done approximately 5 factory data resets yet the background image that my friend has on the tablet as well as seemingly every single setting and application is remaining untouched..
Try the ones here that also install a custom recovery: http://www.slatedroid.com/topic/33586-a-clockworkmod-rom-compendium-for-the-cruz-reader/
You'll want to make sure and rename the file exactly as mentioned there on the OP. Install instructions are included too. I don't think there is a way to reload via the PC. The right zip should get everything working properly.
The multi user and guest account feature is not available on either of the two recent releases of Lollipop for the Z3v. I did some research and it appears this is the case, not only on other Verizon handsets like the Droid Turbo and the Galaxy S5 / S6, but a few other non-VZW devices as well. I'm not sure why it was removed but apparently it's just hidden. It can be enabled and I followed the instructions for doing this for the various other devices and can report that it works for our Z3v (see attached screenshots).
I've kind of cleaned up the instructions and put them below. Usual disclaimer - I'm not responsible for anything that may happen to you or your cat if you choose to do the following. You DO need root access to edit and write to the system file.
** To be safe, please make a backup of your phone and/or a copy of the build.prop file that you are going to edit.
Get ES File Explorer. Run it and enable Root Explorer setting. (You may be able to use any file explorer and editor with root access but this is used most in the instructions and works.)
With ES File Explorer, go to device/system/ and find the file: build.prop
Choose to edit it with ES Note Editor.
Scroll to the end of the file and type in the following:
fw.max_users=5
fw.show_multiuserui=1
Save the file.
I'm not sure if the next step is required but it was in half the instructions I saw, and I did it myself: Click and hold the file, go to Properties, and then change the permissions to Read, Write & Execute. [all three]
Reboot your phone.
When you're up and running, access multi user mode by pulling down your notification shade and then clicking on your user icon at the top right corner.
Notes so far:
A guest user does not have access to the original user's files on the internal drive - the guest user has their own file directory. The guest CAN access the External SD Card, though.
Therefore, an app such as Movie Creator can and will create a "highlight" movie that is composed from photos that are saved on the external SD Card. Just keep this in mind as far as privacy.
There is a per user option that lets you decide whether or not the additional users can use the phone and access the text messages. If you disable this ability, while they cannot open the phone app to make a call, the CAN receive an incoming call.
You can find out more about the nuances of additional users with your Google Fu.
Enjoy!
Wow! Great work!

Thanks! I really wanted this feature and it seemed like not many people care too much about it. It's my way of circumventing the awful permissions control we currently have in Android. That is, there are apps I want to use but refuse to install because of their overreaching permission requirements (contacts, etc) and so I can now create a second user with a new "dummy" Gmail account that has no sensitive information and install these apps without worrying.
By the way, something neat I figured out about this. Additional user accounts are not allowed to side load apps (the toggle to install from unknown sources is grayed out). I figured out that if the main user / owner restores an app through Titanium Backup, any other currently existing user will have it installed for some reason. I don't know why this happens but it's a neat glitch that gets you around that restriction.
Well I think most people simply don't let others touch their phones and so don't have a use for multiple user accounts. I find that my phone, as big as the screen is, is becoming more and more of a computer / tablet replacement. I like the idea of a multiuser functionality, but mostly to hide my own stuff. I'll silk never let anyone else touch my phone!
The use for multi-user that I've seen that makes the most sense is people with children. They will create a user profile for the child so they can't get into any of the parent's stuff or settings. That or the guest profile which will let them do whatever the heck they want without screwing up the phone.
Aside from that I have read that devs find the feature very useful for testing. Heck, that's not a bad idea to install and test apps, in general.
uh oh.
Well something didnt work. Maybe a certain build I have to be on or what. I followed the instructions to a t. Now stuck on endless boot loop. Only bad part is I'm on as hotel room working out of town without a laptop Or pc to fix it. I used a one click root just today and didn't install a proper recovery. Any thoughts

I had a problem with this also twice cause I'm always doing stupid things to my phone my guess is you didn't change the system to r/w but modified it anyway or you used a editor that would let you input the correct values I used s manager I think. As far as getting your phone working you could try safe mode or maybe a factory reset if you can hold power and the volume button down and enter recovery.

I believe the mistake was made when i changed the permissions per instructions. I finially got to my house and im using adb to freeze the loop then going to push a script over to fix the permissions. I will update when i get it done and I will post my fix. Also I used ES file explorer, which i have already used it for years now. Never had anything like this happen before. it just baffles me. I have never got any instructions off of XDA that led to any malfuntion of my phone. But oh well, sh!+ happens.

Hey! I'm so sorry! I got a couple of new phones (Droid Maxx 2 and LG G4) and have been using those phones so I haven't been checking these forums like I was when I just had the Z3v. Really sorry to hear that you ran into that kind of trouble . Thing is, the instructions above are culled from 4 or 5 different sets of instructions for various devices that I found across the web. I performed them step by step myself while cross referencing them to each other and combined them all to the instruction set above as I did it. Did you ever fix it with the method you mentioned? I'm curious if it was the permissions thing (odd, because it worked for me).

it is guys if done right your system needs to be switched to r/w then go back to r/o after modifying the build prop if you modify in r/o you will get bootloop to a hard brick it depends.

Well I kinda fixed it. I went and bought a HTC M9. Lol but not yet, I'm still working on it. I have found scripts to run, even a specific build.prop fix to push, but I have windows 10 and couldn't get adb to find the device. Plus I'm a little rusty. So I broke out my old windows 7 laptop I have used just for rooting an modding phones and tablets. I did get adb and fastboot to find it once. Then some reason lost it. I didn't have it ready to go. But I'm almost 100 percent sure I can get it. Just need to play around with it a little bit more. Having trouble with drivers etc. I will let you know when I have it.
And didn't really hurt my feelings getting the phone I truly want. I never had problems with HTC since I was flashing roms on my old window phones. I just want my pictures I cannot replace.
"Run it and enable Root Explorer setting. (You may be able to use any file explorer and editor with root access but this is used most in the instructions and works.)"
Alas- I am not rooted, and therefore can not enable "Root Explorer" option. Unless someone has some other suggestions- I think I can't do this unless I'm rooted.
Well this is probably what I did to brick my first z3v.
I don't suggest anyone do this at all. There does seem to be an issue with the permission setting on the build.prop file. If it's not reset correctly after editing, you'll get stuck in a loop or worse. I'm stuck in bootloop, but can get into recovery. I made a backup hoping to learn how to edit the build.prop (delete it and rename the copied original to set it back as it was). But I can't even run the original zip that GigaSPX made up for us. (I don't have a backup like I hought I did.)
Anytime I try to install the flashable prerooted zip it tells me it's done after 2 seconds and says;
set_perm: some changes failed
I'm typing this on my z2 tablet, which has the multi user feature enabled. I'm going to see if RootExplorer will give me some clues as to why this doesn't work.
In the mean time I'm hoping someone can help me out?
If love to get this feature to work, but it has to be safe.
Just checked the build.prop on my tablet and got no clue.

a backup usually means going into your twrp and hit the back up button and make a copy of your system including data and all that. This is mandatory before messing with the build prop. If you want Pm me your build prop and I will send it back to you. With multi user enabled.
Yup, I know what a back-up is and how to do it, and I know it's a must before messing with the build.prop. I just really thought I had done it recently...
-and I had! But I forgot that a few days ago I bought myself a Christmas present; a 200 Gb micro SD, and copied most of the contents to the new card from my old one. I chose not to copy the backup because I had planned to make some changes and create a more recent backup. Never happened though because I got side tracked loading music and such. Lol!
So I'm all back together, but would still like to play with this feature. So I'm going to give it another shot.
A guest user does not have access to the original user's files on the internal drive - the guest user has their own file directory. The guest CAN access the External SD Card, though.

Perhaps the wrong thread but: enabled multi user on a Cube T8 only to find that guest and other user can access INTERNAL sd but not external sd. I'd rather have it the other way round. So the kids (other users) can use the whole of 32 GB sd card rather than me having to share the small internal sd with them.
Any ideas how to fix this? Phablet is not rooted btw.
got bootloop..... but i'm safe as i've backup.... through recovery..
I've inserted two lines and fell in bootloop
Thanks bro.. working....!!!! but second step is not needed...
Hey! I am trying to get Cyanogenmod 12.1 on my stock Nook Tablet. I no longer use the Nook Tablet as often and would like to give it a new life by making it an Android. After reading a ton of articles and forums, I have tried a ton of them, but none of them seem to work successfully. One of them I tried was, Install CM for acclaim on the wiki.cyanogenmod.org website , the process went successfully until I rebooted and it continued to boot me to the regular Nook setup. I think it is because the Clockworkmod Recovery is outdated. I also see that Cyanogenmod's latest recovery is also available, but how do I put it on my SD card successfully. Please provide a step to step guide for me. Thank you!

I just did this about a week ago (finally) and there are no better instructions for getting started than those provided by digixmax here. Just ignore the statements about CM 11 and forge ahead. Later in that thread there are a variety of recommendations for file substitutions in the method if you are aiming for CM 12 instead of 11. I followed the ones here. These also work.
My own discovery was that you should ignore the TWRP error messages about being unable to mount '/bootdata'. I finally came across that somewhere and it proved to be true for me.
Take it slow. Gather together all the files you will need first. Then prep the SD card (don't forget to set the flag). Then copy the files over in the order specified. It matters. Then go for it! (don't neglect to backup the stock system before wiping things--you may be glad you did).
My start-up with CM 12.1 was really rough and I thought I might abandon it but after a few days and quite a number of reboots things settled down. Maybe that has something to do with coming from CM 10.2.1, maybe not. Anyway, the system is no worse than CM 10.2.1 and I don't have trouble with cold or warm boots hanging like I used to with CM 10.2.1.
My pet peeves are listed here and/or here but may be idiosynchratic to my device or particular flash.

I literally just finished sending a message to digixmax when you posted this. I remember seeing you in the other forum, trying to get CM12.1 to install. I did all this instructions over and over for hours, but I keep getting stuck at the CyanoBoot section. I get the Boot Menu, but then the SDC Recovery option isn't available, I see it, but it isn't clickable.

Wow, everytime you mention digixmax, he replies. He just privated messaged me in return.
If you can get to the CyanoBoot menu but its menu entry for "SDC recovery" is greyed out then it's because CyanoBoot (flashing_boot.img) cannot find a recovery.img file on your bootable SDcard.
Which version of SD-based recovery did you download and use?
You might want to wait for and check against the answer to my inquiry post at http://forum.xda-developers.com/showpost.php?p=65016892&postcount=41 (I no longer have a NT and as such cannot vouch for any specific recent recovery versions).
I'm sorry, I should have been more precise. I don't know if it will help, but this is the TWRP recovery image I used successfully when I tried this process. That's v. 2.8.6.0

Don't give up. If you're using a Windows machine to prepare the card then whether the .IMG is displayed or not depends on your settings. It does not show on mine but a look at the file properties shows it is an .IMG file.
So that's the wrong tree. SDCards have been known to be problematic so if you have another around you might want to give it a try. You also might do a slow (complete) format on it before preparing it from scratch.
The other thing, of course, is the integrity of the individual files. Checking the MD5 values is a pain but sometimes reveals a bad download.

I've already shut down my computer for the night. I'll have a look at the size that an image of the card would be. Maybe that's the easiest way if there's room in my dropbox. If you've read through the CM11/12 thread you know I ran into problems and if you were to look at the CM10 thread you'd find me floundering around there also, so I know how frustrating it can be. And then suddenly it just works.
I'll let you know tomorrow.

As @nmyshkin pointed out, it's most likely because your Windows Explorer is configured not to display the file-name extension, so when you try to rename "flashing_boot" to "flashing_boot.img" you in effect end up with a file with name "flashing_boot.img.img".
This is likely also the root cause of your original problem: if you now just rename the TWRP recovery file you had downloaded (which already has the hidden .img extension) to "recovery" (and not "recovery.img" lest you end up with a file named "recovery.img.img") then CyanoBoot will see the recovery file.
For avoidance of doubt, just set your Windows Explorer to display file-name extension.

You are totally correct. I enabled Windows Explorer to display file-name extension and the TWRP recovery file turned out as "recovery.img.img" I am going to try it out now and reply with if it works or not.
