[Q] Cannot update to 15R from 15Q...and more - Nexus 7 (2013) Q&A

I cannot get my N7 to accept the 15R update. I have tried OTA, have also tried flashing the zip and sideloading the zip through ADB..always get an error that looks to be a mismatch of the hash. So ultimately I will end up wiping and re-installing...but my question is more than just that. My N7 is rooted with NRT but with no other modifications. The only reason I rooted was so that I could use Titanium backup. I hear people constantly concerned that they will lose root after an OTA update. I don't understand this because re-rooting is so easy and takes only a couple of minutes. I am much more concerned with not being able to update and having to wipe the device. This requires lots more time and effort...even getting my wireless password into the device (63 digits) takes longer than re-rooting. I have to temporarily change the password on my router to something that I can type in, then change it back after cutting and pasting in my real password, which is too long and complicated to type.
What am I missing and also, is there anything else I can do to get 15R into the device? (I have SuperSU 1.65 already.)
Thanks for helping a newbie.

Something changed after you rooted. It may not have been explicitly something you changed. It could have been one of the root apps you started using. For example stickmount will often result in the hash for debuggerd to fail.
If you post the exact error someone can probably guess what you installed that caused the hash failure. I assure you it only happens if a file was modified or deleted (unless you are one of the unfortunate with suspect eMMC memory that is corrupting on its own)
The quickest way to get JSS15R is to just use this post in JSS15R discussion thread. Use the nowipe factory option and it will preserve your data.

Thanks for the response...I will get into that thread suggested. For the future, if an app screws things up, will uninstalling it fix things or not? You mentioned Stickmount, which I have installed. I went ahead and uninstalled it, but results are the same.
When trying to flash the 15R zip, I get:
skipping MD5 check
no MD5 file found
assert failed-apply patch check [zip name]
error executing updater binary
error installing zip
this is all while booted temporarily into TWRP....I have stock recovery on the unit.
Could freezing useless apps (some system like Google Books and useless keyboards) with Titanium Backup cause the update to fail? I tried unfreezing everything that I had done...still no luck. I'm just trying to get a feel for what to do and not do in the future...
Thanks much!!

OK...followed your thread ...read everything and since I saw an error about debuggered somewhere on my N7, I used your debuggered update, flashed it with TWRP and then was successful in flashing the 15R update.zip. So it must have been as you said...Stickmount was the problem and it messed up the debuggered file. I'm still wondering if freezing apps with Titanium backup will mess up an update or if I did not need to defrost everything before trying to flash the zip???
Thanks so much for the help...another success story and noob learning more and more about what the heck is going on in Android.

It has nothing to do with freezing apps. Freezing apps won't have any negative effects on your ability to use an OTA successfully.
Stickmount backs up debuggerd, makes some changes to it, then restores the backup, but sometimes it gets out of sync. When it gets out of sync, your original debuggerd is lost even though there is a backup file because the backup is of the wrong file.
Uninstalling stickmount wouldn't have fixed this issue because it already made the modification to debuggerd.
Keep in mind, normally it isn't root that causes the OTA to fail. It is the use of those capabilities root gave you, to modify or remove files, either directly or indirectly through a 3rd-party app that causes the OTA to fail.

Gotcha...thanks for the help...your debuggerd script fixed everything...I've put it away for possible future use. Titanium Backup and Stickmount are the only apps I have that require root...I will keep this in mind. To a lesser but similar extent than in Windows, I like to keep a system lean and mean....I think Android can benefit from this also.

[Q] Titanium Backup Failing Since License.

Not sure where this question goes, I figure here but...
Last week I planned on trying out a few ROMS, I've been using Titanium flawlessly but with 48+ apps I decided to buy a license to bypass all the prompts.
And this is where the problems started. I still have not tried without the license file installed, I know I should.
I create a backup, verify the backup, flash a ROM and 1) flash install Titanium or 2) install from the market, start restore and the phone crashes back to the bootanimation, verify the backup now and every backup will have errors.
I posted this on the official Titanium forum and got not response.
Update busybox
I've tried that both before backup and before restore.
when titanium restores it kills the process it is restoring. if you are restoring the whole system instead of just your user apps, what you are saying will occur.
I am not restoring any system files or even system settings.
Only user apps and data.
I removed the lic file. Next flash I'll try a backup/restore and see what happens.
Tha'ts the only difference.
email the dev. he is great at helping and is damn smart.

That was one of the issues. The license was sent from a noreply address and support is direct to a forum.
However I just checked my paypal and sent an email to the address I paypal'd the donation.
I deleted the lic file from the SDcard and even rebooted and Titanium still shows as registered.
I'll hope that's a good email address and wait for an email response.
Sounds like you are having a similar problem that I was having. Are you letting TB auto restore settings from your sd cards? I turned that off... Deleted the files from the sd card... And haven't seen that problem again. I used mostly default settings so id prefer to just have to remember to adjust the few settings I liked whether I did a reinstall. (also.. Now that I'm thinking about it.. I also adopted trying to flash tb and inse instead just install it from the market... ) give both a go.

Not sure what you mean by that. It the same settings I've been using.
Again the only difference being the license file.

Debugging has always been on since before using Titanium.
Now to make it really interesting.
I've been playing with ROMS the last few days, I'm cooking a ROM from the latest RUU so I'm done now.
I've backed up in Sense, with the lic. I restored in a clean install of Cyanogen.
I also made a backup in Cyanogen and restored to a clean install of Sense.
I had to install each program manually with prompts but no errors and everything worked. No missing SDCard of data not working. I left those problems out.
I have a clean backup made in a Sense ROM and will try to restore to my new Sense ROM.
I previously deleted the backups through Titanium and also deleted the folder on the SDCard.
I once formatted and restored my files to the card while all this was happening.
As of now the restore seems to be going well.
-edit: Restore is finished and everything is working. Not sure what went on unless Titanium just doesn’t like the Snap Kernel.
I had this same TB problem after getting the license file. In trying to figure out the issue, I discovered that I had somehow managed to lose full root (i.e. NAND re-locked, s-on), my radio reverted to like 1.39.x (and reflashing the latest would not stick), and my HBOOT version had changed to .79 (or whatever the original shipped version was -- as opposed to the .76 version from Toast's root part 2).
I seriously doubt that the TB license caused all of those problems (though I can't for the life of me figure out how on earth that happened), but for others experiencing similar problems, double check that you have full root.
Is it hanging on the restore? Go to prefererences and change the restore type to "indirect."
There is an update on market for tb that says it addresses some license problems.
I did not lose root, All root apps still worked and I was able to flash all ROMS, themes, etc.
Although I do belive the ROMS I was restoring to were 3.29 OTA based. My current is 3.29 RUU based.
Nothing was hanging for me, just a crash, not an app FC, and all backups then being corrupt.
It's worked great when I flashed my current ROM. I even went back and forth a couple times playing with Cyanogen.
I don't know what happened.
did you get a response back from email
Same thing happened to me. went from a rooted Stock with s-off to Myn TwoPointTwo and formatted new SD card with A2SD (SD-ext) partition and backups verify as all corrupted. Tried Traditional restore and some could not be parsed. Also the Data for some completely corrupt.
What is odd is that some older backups were fine but newer ones where not. Even tried re-copying from a backups from PC and Dropbox.
Finishing re-install then going to wipe backups and try again. Its a real pain to manual reinstall and setup.

Defrost frozen apps before OTA?

Hi, I've frozen (but not removed) some bloat apps such as "My Account" and "Tethering Manager". I just want to know when an OTA is available for me to install, do I need to defrost these frozen apps before I accept the offer? Is there something else that I need to do before accepting the OTA?
defrosting before an OTA would definitely help
as it would expect some of the software to be updated already present in the system
if they are frozen, whatever it needs to be updated, might not be found, and could cause some unexpected problems
also after OTA you will most likely need to re-root the phone again, as some OTA removes the root if it needs to update the system files

Thanks for the answer!!
Does an OTA update completely flashes a new firmware, or does it just updates some files / install some apps / etc on the original firmware?
Also, after a OTA update, if I factory reset the phone, do I get reset to the old system, or do I get reset to the system after the update?
Sorry for these noob questions....
it depends
it will come in the form of update.zip
that the stock ROM will pick up automatically to flash, so it depends what comes packaged inside the update.zip file

Maybe it should be mentioned that you need TWRP to flash the zip file. Thanks for the efforts, though. I'm sort of dead in the water until I am able to get my unlock code.

LOL. Good point. Sorry about that. It just wasn't very obvious. I guess I got excited and jumped in.
So, does this script removes the app that tries to police the background apps from running? I think it was protected apps under settings? If so.. awesome. we wont have to manually add them after install.
Is it possible that if I was on one of the restricted battery profiles when I ran the debloat script that it could have stuck?
When I first got the phone I put it normal mode and found it pretty good. Even running the Google launcher. However, I have now unlocked the bootloader, installed twrp, rooted, installed MOAB ad blocker and debloated the phone feels slow and janky?!? I figured dumping all the bloat would help to speed it up some. Any suggestions or thoughts?
Thanks,
Justin

Try removing the unnecessary zram operations using the no-swap method at -
http://forum.xda-developers.com/hon...ipt-disable-enable-swap-honor-5x-kiw-t3308321
When you debloated you removed a number of unnecessary processes and now it's trying to use the ram you freed up by keeping more of your apps in memory - with a constant compression/decompression process that adds lag on the 5X (and every other phone I've checked out that uses it).
Huawei - like every other phone maker with a new launch - will also be releasing performance improvements soon. I've tested both of these mods with the update coming next and you'll still want to use them.
The normal power mode ought to be sticking. If the no-swap mod doesn't help then it's probably a good idea to regress back with a nandroid backup, ensure normal mode and then de-bloat and remove swap.
Edit - and be sure to protect all apps in settings so that you get standard Android task management and not EMUI task management.
Is there anyway to selectively re-install some of the apps that it removed? Im curious because I think it some functionality like HwThemeManager_Local removes the ability to change the lock wallpaper. and if any other issues come up that i want to undo. (Can i somehow restore the individual items from a nandroid backup?)
And thanks for providing a nice commented script!

I don't think that you can do it directly.
Right now, it's restore your nandroid backup, modify the script here and debloat again.
I've started into an Aroma installer for this so you can just select the bloat you don't want. That's on the back burner with no ETA yet.
Meanwhile - if you want to wait until later today or tonight, I'll pull the file you want and you can reinstall it by hand.
If you don't want to wait, copy your nandroid system.ext4 to your pc (if not compressed) and rename it to system.ext4.tar - I believe that 7zip will work to extract it to your pc and you can find the file and put it back from there. (And I'm going by memory here so you'll want to be prepared for hiccups.)
There may be a utility for this - I think there is, but can't remember it.
OK - just checked another option for you -
My system nandroid spans volumes.
Copy system.ext4.win000 to system.ext4. win000.tar on to a large sd card.
Check out "ZArchiver"
https://play.google.com/store/apps/details?id=ru.zdevs.zarchiver
See if you can extract with that, and if you can, repeat for all volumes.
No promises but you'll probably find the attempts very informative.
Thanks for the info. messed around for awhile trying to get something. I found out Titanium Backup has an "extract from Nandroid backup" feature. you select the backup and it lists the apps that you can restore. The only one i found that looked like the theme manger was: com.huawei.android.thememanager i click on that and restore and it takes a long time (which makes me think TiBu is not working right) about 1-2 minutes (but it does eventually say success), reboot and still cant change the lock screen wallpaper. I also copied the system.ex4 files to windows and renamed them tar. extract them with 7zip and it kinda locks up after a bit. it extracts some extension less files. So maybe im missing some additional files, or Tibu is not really doing anything. i tried mounting system as RW just in case. No biggie, i dont think i want to spend much more time on this. Thanks for the info though. Ill take a look again later.

Ok, so I was going to try and just go back to the fully bloated stock, rooted rom.... however I messed up and somehow didn't do a backup first.... so I have nothing to restore. I tried to download and restore the "full Stock" backup from the other thread, however I'm getting errors for no partitions. I then downloaded the factory firmware from Heuawi, but when it tried to install it seemed to be working, but then booted into TWRP and won't go further. Anyone have suggestions on how I can return this thing to stock?

Ok, I was able to get it all sorted out, I just had to calm down, think, and teach myself some new comand line skills hahaha
I downloaded the stock Firmware, however I wasn't able to install it since I had TWRP and it was blocking it.... so I found this tool, Huawei Update Extractor that can be found here: http://forum.xda-developers.com/showthread.php?t=2433454 Then used this Extractor to expand the firmware and extract the stock Recovery.img out of it. Then flashed that to the phone via fastboot. Now, I was able to run the stock firmware update via the factory EMUI update app. Once that was done I was able too boot the phone back up and I was suprised to find that it didn't wipe the phone, I guess it ran it as a true "upgrade" instead of a nuke and pave.... BONUS!
Anyhow, then I was able to flash the new TWRP recovery back in place and now I'm currently creating a backup.... which if I had taken the time to do in the first place none of this would have happend. Oh, well... who needs more than 3 hours of sleep..... its not like I work full time and have 5 kids under 5 :silly:
Hope this helps someone who gets flash happy and forgets to make a back up like I did!

Does it work with KIW-L21?

It might. Pre-installed apps may vary by region, the Aroma installer (under construction) is intended to be intelligent about that.
Either way, make a nandroid backup before trying to debloat and you won't be stuck if anything goes wrong.
Worked for the most part.
There were some apps left (mostlygames that came preinstalled as well as Shazam and Instagramm)

New Tab S 10.5 Owner! Need Help/Suggestions

I just ordered this beautiful tablet. I've never owned a tablet before. I've actually always wanted a laptop, but things are changing. I have an Amazon Kindle Fire HD from many years ago. It's actually worked pretty well for me for ebook reading, limited web browsing and email using. But, the last few months it's really started acting funny and not working right. So I've decided it's time to upgrade. Did a week's worth of research and decided this is my best option. I haven't received it yet, but I'm really excited to dig in and do a lot more than I can with my Kindle.
So that brings me here. I don't remember where, but through my research on which tablet to buy, this website was mentioned as a major resource. To be completely honest, I'm 100% lost. There are things I want to do but I don't even know where to start. I love tinkering and figuring things out, but I need a little push in the right direction.
One of the biggest things I want to be able to do is make a complete low level backup of the entire system to store on my home server should anything happen and I need to restore it.
The other big thing I want to do is remove all the excess junk that comes pre-installed that I'll never use. With such a small area of space available, having half or so used up in unnecessary stuff is just pointless.
I'm sure there are other things I can do and may want to do in the future, but for now, these are the major keys. So... any help? Did I make the right choice? What other features/functions should I be looking at or considering?
Thanks guys! Looking forward to getting a lot of great use out of my new tablet and this site.

Root with chain fire root, flash via Odin.
This will allow you to have root access allowing you to remove unwanted app amongst other things
Flash via Odin: TWRP Recovery for Chagallwifi (assuming it's a Samsung T800)
This will allow you to create a back up.
I believe the order of this can be inverted. IE. Flash recovery with Odin and then have TWRP flash the CFAutoroot zip and the SuperSU (the app that will "manage" your root)
Install Titanium Back up and freeze/uninstall unwanted apps. There are lists of removable apps on the forums. I prefer to freeze but it's up to you.
!!!Make a backup prior to this step!!!
Will update post when I am home with more suggestion's.
Thanks, that's somewhat helpful. At least it give me the names of programs. I have no idea what I'm doing though. Can you give me a link to a step-by-step guide, or at least explain what the different things are and what they do? Sorry for being such a noob with this.
Instructions
MAKE SURE TO DOWNLOAD THE FILES FOR YOUR SPECIFIC DEVICE (T700, T705, T800, T805, etc.)
You will need Odin (This is the software that will allow you to install the root and other files [FLASHING])
CF-AutoRoot (Will provide Root access for your device): You will be flashing this with Odin
Optional: Install custom recovery TWRP. This is also done with Odin. This will allow you to make backups and flash .zip files, including custom roms, apps, etc.
Just google for guides on rooting Samsung Galaxy Tab S. They will show you step by step on how to do the Odin flashing, PDA, settings, autoreset or not, etc.
I recommend backing up your device at this point. Reboot into recovery (instructions will be in the rooting guides), go to backup and backup everything for now. In the future when you feel comfortable enough that you can/will select to only backup what you deem necessary.
Your device is now rooted, the first boot after installing CFAutoRoot will take awhile +/-3 - 5 minutes.
Now download Titanium Backup, and you can google or search XDA for a list of "safe" things to uninstall. Just go into TitaniumBackup and look for the app you want to Freeze (This will prevent the app from running but it will NOT delete it, thus it will still take up space) or Remove.
Busybox: Will be required by certain apps.
Optional:
Link2SD App, this allows you to install/move/link your apps to the SD Card, it essentially frees up your internal memory of the device and tricks the device into installing apps and their data files onto your second partition of your External SD Card (Google or Search XDA for guides on Link2SD). This will allow you to install a lot more apps than you normally would be able to. (Example: Vice City, San Andreas, Plants vs Zombies, etc. I mention these because of their large data size). Not all apps will work when linked, just trial and error. I can't seem to get Word, Excel, Powerpoint linked to my SD Card without at least one of the failing, same with Facebook. You will have to test each app and see what files you can link/bind and which you can't.
Adblock Plus: Self explanatory
Xposed: A bunch of customization options for your device
ES File Explorer Pro: The best file management/directory app IMO
Greenify: Battery saver
Aptoide: Secondary App Store
Hancom Apps: I feel these work better on occasion then the Microsoft Office apps (Example large excel files with multiple formulas and filters)
NovaLauncher: Custom launcher, a lot more customizations then TouchWiz will provide you. (Your home screen)
Tasker: Limitless possibilities with this app (Search google/XDA for info)
TWRP Manager: TWRP Recovery app.
VLC: Video player
4way_multiwindow: This will allow you to have 4 apps open at a time and 3 apps "minimized", this also allows floating windows (Moveable apps running in "windowed mode" essentially.) There is an aesthetic bug when minimized, I have not found a fixed version of this yet, maybe others can provide link. Just load up TWRP manager and choose install, and select the .zip file and it will reboot into recovery and install the file for you. Or you can boot your device into recovery and install it the same way. I am attaching the .zip file.
If you are happy with your device up to this point, I would create another backup after you are done with the initial set up and have installed the apps of your choosing. Save a copy on the device, PC, NAS, etc. just in case you lose one of your copies. Some TWRP versions do not allow you to backup directly to the external SD Card, you may have to backup into the Internal and then transfer the information over to the external SD Card.
Good Luck.

Doesn't installing Chain Fire Root via the previous link also contain the TWRP Recovery? Or is this a special version I need to install after running the first root through Odin? What is Chagallwifi?

This is just an app I get from the Google Play store right? Or is there a special version I need to get, or install manually? I think I saw in a YouTube video that I need to install something called GApps if I want install something from there after rooting, is this correct? Also, if Titanium Backup IS an app, how can I get a backup of the entire system when I'm booted into the OS? I think I read somewhere, or saw screenshots that show this basically creates backups of your installed programs, so you can easily restore them without having to re-download them. Maybe I'm wrong, as I said I'm completely new this and probably don't know what I'm talking about.
My biggest concern is that I'll screw something up and find myself with a tablet I can't use, without having had it no more than a couple days, and having spent nearly $600 for it and the accessories. I know that rooting/etc voids the warranty, but I also have seen where people are able to put the whole system back to factory default for repairs, etc. That sounds like something I really need to learn how to do and be confident I can do should something happen.
Thanks again for any help!

This link works, although there are newer versions of TWRP, you can install these after however, no big deal.
Doesn't installing Chain Fire Root via the previous link also contain the TWRP Recovery? Or is this a special version I need to install after running the first root through Odin? What is Chagallwifi?

The previous link contains TWRP, read above. The normal CF Autoroot comes with CWM Recovery I believe (A custom recovery similar to TWRP). You can use the link you posted. Chagallwifi is the "nickname" of the Galaxy Tab S 10.5 WiFi, it is one way to search for a device, the other being the model number T800, for instance or the long commercial name.

You get the app from the playstore, correct. I am not sure about GApps, I want to say it isn't necessary unless you will be installing a custom rom (you can double check this on the rooting guides, if it asks for GApps, then flash the GApps)
The system back up is done via TWRP or CWM, boot into recovery and choose backup.
Titanium Backup allows you to back up the app and its data file. So you don't lose the progress of your games. Also backs up email, WiFi passwords, etc.

Most of the errors cause soft bricks, you can recover from these. I would recommend you backup after rooting, in case you mess something up toying with Titanium, Link2SD, SuperSU, etc. You can always use SamMobile and find a Stock Rom to flash back onto the device, again via Odin. Not sure if the KnoxTrip flag will still show up, you can trying Googling how to root without tripping Knox, I know there are methods, however I have never used them. I have soft bricked my device before, I deleted everything with TWRP, I wanted to factory reset, and I selected erase System..... scary times.
Stock Rom: SamFirm (Outdated) or Updato
Thanks for all your help and advice. I just got my tablet today. Still kinda playing around with it. I probably won't do anything for a couple of days. At least till my next day off from work (Thursday) so I can concentrate on what I'm doing. I was really scared when I first turned it on, everything was in Korean. I had to find a YouTube video showing how to go through the initial setup to change the language. All good now. Once I got it fully running, it downloaded a 350mb update and rebooted. I'm now running Lolipop 5.0.2. Is that going to cause any issues? Also, I can now confirm that it is model SM-T800.
Thanks again!
ChewVodka, once your past the learning curve rooting etc. can be done in your sleep. After some research, I rooted a 10.1 tab 4 a while back with no problem. Definitely better o have more control over the device, I think. Just got a new 10.5 also, and am looking around for the best way to administer the Android system - the Galaxy Tab S for Dummies book seems to me to be actually a good place to start. I'll check back here with any choice info I find on the 10.5.
Also, I have this case for my 10.1, and this is the best under $20 case you can get for the 10.5 - so cheap I bought two of them! Type in search: Xtra-Funky Exclusive Samsung Galaxy Tab S, 10.5 -- the black and navy blue are cool -- the others kinda garish.
Easy Way, allow installation of 3rd party apps in settings download this for android https://kingroot.net/ run it select install anyway when you get the pop up, and root device , open Playstore download flashify for root users, run it allow it access , click recovery image then download twrp choose the 3.0.2-0 release and install to your tab and reboot into recovery, at this point you can use it to make a backup of your current rom or install a custom rom (following the directions on the page for the rom that you choose), this is easier method if you aren't familiar with odin and don't have the drivers and all set up on pc. You can also change kingroot over to super user in a few different ways can download and use supersume from play store and run it or, just flash the newest superuser in twrp and remove whats leftover from kingroot manually after reboot. If you intend on doing a custom rom i suggest choosing first and having all files available before you start. However if you intend on using odin You might want to install this first http://forum.xda-developers.com/showthread.php?t=2317790 so you have full communication with the device in case anything does go wrong there will be other options. This is of course if you are not already setup with this already. Also I would like to note there are a few roms here based on the stock firmware if you like it just look through the forum see what you like, and read everything.
What are the benefits to a custom ROM? I assume you're talking about things like Cyanogenmod. There are some people in another forum I visit that like it, but I don't know what it is or why I would want it. Does it allow installing pirated software or something? It's probably not allowed to be discussed here, and I'm not saying I would purposely do something like that (not that I wouldn't if possible lol). It all comes down to the fact that I'm completely new to the tablet world, other than the fact that it's a bigger and better Kindle Fire that I can get more usage out of by not being limited to Amazon's ROM and store for apps. The biggest things I'm looking to do is get rid of bloatware that came preinstalled (of which a lot was added with the update) and the ability to make backups of the entire system should something screw up.
It sounds like "rooting" is essentially giving you the administrative control access to the system (like in Windows) instead of being limited to a generic "user". That allows you to install more system accessible programs, where a generic user would get a UAC prompt and then be told and Administrator needs to preform that action. As for "recovery", it sounds like that is sort of like the CMOS/BIOS of a PC. It's the first "program" that runs when you boot up (even requiring a specific keypress to enter). This allows you to access the system before the system boots, to get you backup/restore functions, and the ability to install new OS's. It also sounds like the built in version from Samsung is what is getting changed (like updating the BIOS of the PC) to allow more functionality (like backups, etc). The only thing you don't have access to is stuff like disk drives, but things like RAM and CPU can be adjusted once you have ROOT.
The more I learn about it, the more I'm eager to do it. I really don't like feeling confined to a predetermined set of available things to do, and I really don't like having somebody decide to install software I'll never use on my system that just takes up space. I especially hate that said programs can't even be uninstalled. Looks like this is what I'm gonna have to do!
Decided not to wait and rooted it tonight. I have the freedom now to play, though I'm not sure where to start. Currently I have the CF-Autoroot thing done, and it installed SuperSU. Then I did the TWRP recovery, and made a backup of all the partitions. I was kinda hoping I could backup remotely (like on the computer) rather than stored on the same device. I have a microSD card ordered and on the way, so my next task will be to back up to that. There is a tool I use on my Kindle Fire called ES File Explorer. I'll see if I can get that on this. Then I can find the backup and transfer it over the wifi.
I'll check out your other recommended apps as I have time. Thanks again!
Now I'm having a bunch of trouble. I was able to get the Chainfire root to go through, and verified it with a Root Checker. I then installed the TWRP recovery so I could make a backup. I even have a few backups. Then I went and installed an app called TWRP Manager, that was supposed to enable me the option of making backups LIVE (without having to boot into TWRP). It wasn't working, so I went to do a "Classic Backup" which reboots into TWRP and starts the backup then reboots normally. Well, TWRP never booted. I just had a black screen. Nothing seemed to work. I couldn't power on with the power button, and I couldn't manually boot into TWRP. The only option that did anything was ODIN (Download) Mode. I'm really freaking out at this point. I found a way to connect to XDA's IRC Channel and talked with some really nice guys and was told to try re-flashing the stock. I did that, and it worked. But now I'm stuck again. Basically starting from scratch with a stock system, I went through to install the Chainfire root again. It seemed to work ok, and SuperSU showed up. Ran the Root Verifier and it confirmed it was successful. I then went to flash TWRP. ODIN says it passed, but I still can't boot into it. Here's the kicker.. even if it appears that it's not working, if I do the keypresses on my tablet correctly and wait like 2-3 minutes then try again, TWRP will actually be up but the screen locked. WTF??
So did I something wrong? I'm really lost. Like I told the guys in the chatroom, I'm going on blind faith here, not really knowing what I'm doing. I figured once I have stock installed, I'm basically back to square one and can go through the whole process again. Doesn't seem to be working. I have to go to work now but hopefully somebody has something of a suggestion I can try by the time I get home.

4way_multiwindow: This will allow you to have 4 apps open at a time and 3 apps "minimized", this also allows floating windows (Moveable apps running in "windowed mode" essentially.) There is an aesthetic bug when minimized, I have not found a fixed version of this yet, maybe others can provide link. Just load up TWRP manager and choose install, and select the .zip file and it will reboot into recovery and install the file for you. Or you can boot your device into recovery and install it the same way. I am attaching the .zip file.

Before I try this myself and bootloop, would I be safe flashing the 4way multiwindow on the new stock 6.0.1 ROM? (SM-T805)

Can't move to system

Hi all, apologies for an other thread.
There are so many threads on XDA/ reddit that are sort of related to this, but I can't seem to get the help I need or keep up with them all, so once again apologies, but I have really tried to find the answers myself before asking.
Basically, I did a factory reset/ wipe on my phone, did a clean install of 6.0.1 from the factory images. Side loaded 7 from the OTA update and nougat is great!
I installed the latest TWRP (after a few go's, managed to get it to stick), then installed the latest, N supported SU.
SU is installed and I can run as rooted. However, this is the part I don't understand (very new to all this). While I apparently have root, I can't get an app to move applications over to the system directory like I used to be able to do, doing the same setup.
So, is this something to do with system/ systemless root, or encryption or N, or have I stuffed something?
From all the reading I come up with encryption, then others said it doesn't matter if encrypted... So maybe it's just N and root doesn't support moving to the system...
Anyway, I'm totally lost now. Bottom line is, I can use apps that require root, but no apps that move applications to system can access system, even after granting root access to them.
Cheers.

Something is messed up. TWRP shouldn't take a few tries to stick. The factory images are out now. Flash them and start over.
