Backing up stock 4.4 - MeMO Pad 7 Q&A, Help & Troubleshooting

Hey,
I'm trying to install LOS on my ME176C, but it looks like that I need to be on 5.0 first. The problem is that back in the days I upgraded to 5.0 on release, but for whatever reason it bugged and the tab very often restarted itself. I later fried my mobo, so I don't know if this was fixed, but I have a new mobo now with 4.4.
Anyway, before doing anything I want a backup of stock 4.4, because it's questionable whether stock 5.0 will work properly, but apparently I need 5.0 to even download the unlocked bootloader (according to this), let alone to install TWRP to make backups.
Is there any way I can make backups of 4.4?

Updating after root

Forgive me if this has been asked before. I did search, but I couldn't seem to find an answer to this.
I have a dev edition model. I really want to root, but have been holding off because there are bugs with the current build of Lollipop and I'm kind of hoping Moto will release a 5.02 update soon to kill the memory leak and other issues. That being said, I have really been itching for root.
If I did root, what would I have to do to this phone to update it to the new version? Would I have to completely return to stock and wipe? Or could I ADB sideload? Seems like I was reading that you can't update at all when you're rooted, even if you disable root.
Without any idea how much longer it'll be before the next update, I'm finding it harder and harder to hold off on root, but I don't want to go through hell to get it back to stock and update it.
Thanks for any help and sorry if this has already been asked.
From what I understand, root is fine. It is installing a custom recovery that will stop you from getting the OTA. You can very easily undo root. As a matter if fact, you can pretty easily reinstall the stock recovery also.

Thanks for the reply.
Most of the time, that's true. I have updated a lot of phones by simply unrooting, applying the update, and rooting again, or using ADB sideload and then just rooting. But from what I have been reading about the Moto X 2014, you have to completely restore it back to stock before doing anything, even if you just use the temp boot method to root.
Is that wrong? I can't seem to find any info that confirms either way.
I've installed custom recovery, how can I reverse it and install the original recovery for update?
One advantage of root is you'll have Titanium Backup, so even if you do have to do a full wipe before applying the update, you could just update it and restore everything back quickly using TiBu. With lollipop, apparently the update file checks for the entire system checksum as a whole instead of each file so any slight modification to the system will mostly require pure stock and this is the same even with the nexus. So yeah, you most likely have to wipe your device before updating. I'd say, wait till Xposed for Lollipop is out, its almost there, once it comes out go ahead and root it, it'll at least be worth the hassle then
If you're rooted with lollipop and want to take an OTA update you can flash stock recovery and the stock system image. At that point you should still have all apps/data and be able to take a OTA update. The recovery and system files should be the exact version you already have and of course anytime you flash realize you could lose data!

Right. All you need to do is flash the stock /system partition and also the recovery if you replaced it. I don't know why everyone's talking about having to wipe the entire phone with the all the stock images.

[Q] Will this work for keeping root while upgrading to D41510E?

smart-root.com/f-a-q/keep-root-ota/
Can someone with D41510c try this and see if root stays when you update to d41510e?
No. The OTA Update will break the root and your be back to being partially unrooted (some apps may still work). Basically, the OTA Update doesn't actually do anything other than screw things up. It's still KitKat 4.4.2, just less customizable. If you still intend to do it, though, I would suggest making any changes you desire BEFORE the update. The changes should remain. Also, make sure to make a nandroid backup as there are threads with info to roll-back and re-root. (I had to do that to root in the first place. I got my phone with the 10e firmware.)
I do believe that there it's a stock debloated ROM that has root and is version D41510e. Unfortunately some of the essentials are not working properly, but hopefully that will be fixed. http://forum.xda-developers.com/lg-l90/development/d415-modified-stock-v10e-t3013602

[Q] Lollipop OTA question

I recently upgraded my phone to an AT&T S5 (I decided I didn't like the S6 specs). Currently, the phone is 100% stock, unrooted. I know that previous Samsung phones had problems with OTA updates when they were rooted. Now, with the possibility that the Lollipop OTA is coming soon, I'm hesitant to root until the OTA comes out. Here are my questions:
1. Should I wait to root until after the OTA hits the streets, or is there a strategy to root and still safely apply the OTA?
2. I don't want to be one of the first to get the OTA since it may be buggy. Is there a way to delay the OTA if I'm not rooted?
So, nobody has any thoughts about this?
I can't tell you what you should do but I can tell you what I would do. I would root now, load Titanium backup, and wait for 5.0 to come out. With TBU I freeze the OTA so it's not pushed without my permission. Additionally TBU will backup everything going forward so I can easily move up and restore my apps.
I believe the current process to root will work so be patient.

I wouldn't even take the OTA. Lots of issues with it. I am pretty sure LP will be the same.
I rooted mine, installed SafeStrap, and installed the XDK ROM, which eliminates all updates. My phone works great, does everything I want it to. Don't need problematic upgrades to downgrade my system.

Thanks to both of you for your suggestions. I think I'm going to go ahead and root and stay on the stock rom for a while. If the OTA shows up soon and looks worthwhile, I'll give it a try. Otherwise, I'll install SafeStrap and try a custom ROM.
Sure. Here's an easy answer: if you search for S5 AT&T and lolipop, you'll find lots of things that will say that AT&T will be taking its SWEET time putting an ota upgrade for lolipop out.
It is available from Samsung thru Kies, and I think I am personally going to take a new rom, and try and upgrade and unlock this piece of junque (and I upgraded from a Galaxy SII! )

Rooted kitkat to new 5.1.1 release help

Have n901t. Rooted it after being talked into 5.0.1 by Tmobile rep trying to improve it. No good. So went back down to KitKat and rooted that. Obviously I cannot receive ota update for 5.1.1 now. Do I just get the stock file and flash with the phone as it currently is? Or should I flash KitKat back to it's un rooted state before updating phone? Am still a novice in the taking control of your smart phone world and would rather not brick something if it can be easily avoided. Thank you.

You could get the official software and use odin to install it but there are a couple of things you need to be aware off. First once you upgrade to 5.1.1 you cannot downgrade back to kit kat and you will be stuck on that version, secondly in order to achieve root you might need to install a custom kernel before rooting. For that last part I would suggest you hit the forums since there a couple of posts about rooting this new version.
don't know if I am ready to start messing with kernals yet. Am patient. New root will show itself before we know it. Did the update through Odin. So far smooth sailing. Tested Simpsons tapped out since with 5.0.1 it lagged so bad it was unplayable. Still not as smooth as it was on KitKat but can still play it at least. Haven't tinkered with anything else yet.
Personally I'm waiting it out. I don't like not being able to go back, and I've had 0 luck with 5+.. So I'll wait until someone "fixes" it, if ever.

Root 5.1.1 or 6.0.1?

I have a TMobile Note 4 SM-N910T. It's currently on 5.1.1 stock and I just got the OTA Marshmallow update notification. I'd like to try Marshmallow out, but if I allow the OTA update, will I be able to root it later? Or is 6.0.1 unrootable (for now)? If I root it now (before updating to MM) will I still get the OTA update? And will it still be rooted after the update? So many questions!
ota then root
I OTA'ed, now the phone randomly reboots several times a day, and some apps don't work correctly. Great.
factory reset.
*sigh* I was afraid you were going to say that. Now the problem is backing it up. I have a Titanium Backup Pro license, but I only use it on my old rooted GS2. The Note 4 is not rooted so TB won't run on it. All the rooting tutorials say "back up your phone before you root" but you need root to run TB. Chicken or egg? I guess I could try Samsung Kies, don't know if it will back up everything. My photos are backed up to Google Photos, I guess everything else is replaceable, but I would really rather not have to reinstall all my apps one by one after a factory reset.
That brings up another question: when you to go Settings/Backup and Reset, I have "Backup my data" set to On and linked to my Google account, but nowhere can I find documentation of exactly WHAT gets backed up or to WHERE (it says to "Google servers" but what the heck does that mean? I can't find it on my Google Drive or anywhere else on my Google account dashboard.)
I do greatly appreciate your help, by the way.
You could try reinstalling through kies or smart switch. Make sure to clear caches before and after. And see if that works. If it doesnt help, you could flash recovery, root, try to backup as much as you can between reboots and then factory reset. Your apps should automatically download from play store. But without the titbackup files you'll lose settings and data in a lot of apps that Google doesn't backup.
I unlocked your mum's bootloader.

Were you able to downgrade back to 5.1.1? My phone also download the MM ota but I haven't installed it. I rooted 5.1.1 first and am trying to locate where exactly the MM ota downloaded to.
Been hearing too much about problems with MM.

There aren't that many problems with MM. Just superficial stuff like not having mobile data toggle. The problems you are hearing about a factory reset will fix. Like lag, jankyness, apps loading, phone freezing temporarily. You won't be able to do OTA. It will fail because of root. You need to titanium backup or whatever method you prefer of backing up data and flash through kies, odin or smart switch. Probably easier to go that route unless you only did minor things with root like just block ads, then you can probably get away with flashing stock recovery and then OTA. You still might have to factory reset like I had to even though I flashed whole rom through smart switch. If you have xposed or modified something like swapping recent apps and back key like me, then you'll need to flash marshmallow whole and start over after backing up.
Afaik, you can't downgrade to 5.1.1 unless somebody figured out a workaround or you only flashed everything except bootloader.
I unlocked your mum's bootloader.
@Shad0wsabr3, my phone gave me the choice to delay the upgrade for a while, but eventually just did it without my consent. I suppose you could download stock 5.1.1 from sammobile if you really wanted to downgrade. I just wish I could figure out how to back up my (unrooted) phone so I could then do a factory reset and see if it helps the problems I'm having.

Iv never backed up an unrooted device so I wouldn't know. Glad you nrought that up as Iv been meaning to look into that.
Would you happen to know where the downloaded ota file location is? My phone downloaded it and I keep postponing it.
Sorry, idk exactly where in the file system it is. All I can caution you again is, I kept postponing it and postponing it, and then one day the phone just popped up a message saying it was going to reboot and update, whether I liked it or not. Well, it didn't actually SAY whether I liked it or not but it did decide that I had postponed the update long enough and it was going to apply the update, giving me no option to postpone it any longer. That sort of pissed me off.
Please let me know if you come up with a backup solution. I've tried SimpleADB or whatever it is called these days, and another app that claimed to be able to back up an unrooted phone. Neither of them worked as advertised.
Where are the root instructions for completely stock 910T with MM update?

I'm still researching what your dealing with. As for me I found the ota file. For those looking for it this is how and where I found it....
With RomToolbox I went to root browser. Then to data folder and a folder named fota. Within the fota folder is the ota update named update.zip. I erased that and then went into Titanium Backup and chose to freeze both software update files. So far no constant reminders that I have an update ready to be installed.
Hope this may help.
