[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] globalsearch:
This is my first post here so please be gentle. I have a Note pro 12.2 (p900/WiFi) tablet that I purchased last year after 2 months of reading/doing research/and hands on between it and the Surface3 pro. Biggest problem was I had to go to Florida to actually get my hands on a Pro because no one in the tri state area (MD/PA/NJ) had it in stock or even as a display. And when I bought it i HAD to order it.

Past all that, the Note has been invaluable to me, 64GB plus 128GB card. I use it every day, 8-12 hours minimum. I have not rooted it because I am worried about support. I also have a Note 3 running 4.4.2 - I turned off the auto updates and have refused to allow the upgrade to Lollipop on that device because of all the problems I have been reading about. That device works perfectly. My wife's first S4 did and auto update which completely messed up that phone. So I have experience trying to get those children at the Sprint store to try to help. _anyway, I digress. Today, I checked, an update is available for the Note Pro (+1GB file to download by the looks of it) I would not mind trying it but first I want to do a complete backup snapshot of my device. Just like I do on my pc's and laptops. For example, I use Clonezilla and can image the whole thing, perfectly, and restore it COMPLETELY - at will. I have not found ANY tool that allows me to do that to ANY android device. It is like I am being help hostage. I hate it.

1. I want to be able to get a complete (Clonezilla style image) of my NOTE PRO and I want to be able to restore that should the Lollipop experience be Lollypoop.

2. I want to be able to capture that snapshot of the device with all its settings intact - including the Knox

Can this be done? What tool is there that allows a real complete snapshot of an android device and allows you to restore a previous or older version, SHOULD I CHOOSE TO (from 5.02 to 4.4.2 - something the Sprint children told me is not possible with android)

Any useful help and pointing into a direction that can do this would be greatly appreciated. I know that I am not alone in this frustration with Google forcibly controlling EVERYTHING ( I was livid last year when my Notes upgraded to 4.4.2 and I lost the ability to write to the external card on nearly every app that I had paid for, even sent multiple e-mails to Samsung, to no avail)
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] dcartwright:
Following along

I'm curious about whether that is possible as well beyond a nandroid backup. I'm not likely to upgrade to the 5.02 firmware because I have the logitech keyboard case. If

I've been an XDA member for nearly 7 years, but I don't usually ask much in the way of questions. I hardly post at all, actually. I can usually find my answers by searching and reading the forums. This is my first Samsung device (I've always had either Nexus or HTC phones. & Nexus tablets) and I find working with it to be kind of frustrating. I've kept it stock at 4.4 because it works 95% of the time. The only problem I have is with wifi at times.

I'd like to put an alternate ROM on it and find a way to keep most of the S-pen functionality, but so far the array of "X works, but Y" doesn't info associated with various roms I've read about is daunting.

serious lack of understqnding

Can you imagine, making an upgrade and blowing out a major manufacturer like Logitec? Not some hokum chinese knockoff, but a name brand. This is exactly what is wrong with android. It seems inexperienced and oblivious children are driving it. That is one of the major reasons android was lacking serious professional support and respect all these years. Making boneheaded decisions that destroy existing functionality, for what? A new color scheme? A flat screen lay out? Really, thats what we need?

And when they PUSH the upgrades, its like you are trapped. A cloned backup and the ability to restore to a previous good setup is absolutely essential. I have looked at all these mods of the kernel and tweaks, etc. The fact is that NONE of them have 100% functionality. You always lose something, sometimes a lot. And the gains do not seem to be worth destroying the stock setup. ESPECIALLY WHEN YOU CAN NOT UNDO IT.

The loss of direct access to external sd cards for example, because google is pushing phones with no external sd slots. Really? I avoided apple products EXACTLY because there was no expansion slot. Then google goes and kills it.

Here is a suggestion. NOT ALL DEVICES ARE PHONES. Tablets have been around for years. Enough already with phone upgrades for tablets. Tablets should have their own firmware and operating system.

Here is a novel idea. You want loyal customers? Give them what they are clamoring for. Give them the ability to save their systems. Then upgrade fo your hearts content. BUT IF IT IS A CRAP UPGRADE. Allow them to undo it. Think about how much less bad feedback and emergency support you can avoid. Thats real dollars being save.

And by the way, as unresponsive as Samsung has been, they see the writing on the wall. Android on Samsung devices is heading the way of the dodo. Some skinned version of a tablet/phone linux replacement is coming. It will be one of the first major rejections of google power grab by a major player in the market.

So give us the ability to backup our systems. WITHOUT HAVING TO ROOT, when even that does not guarantee 100% sucess

and the list grows

Judging by the slew of problems, an ever increasing list, Lollipoop is so not a worthwhile upgrade. This is exactly why we need to be able to snapshot/backup the complete system BEFORE ANY UPDATES.

After two days of waiting, it is disappointing to me that no answer has been posted. I thought if any place had it it would be here. I might be wrong.

As you've guessed, you're basically looking for an answer that doesn't exist, at least not the specific one you want. The one you don't? . . . Root and install custom recovery? . . that's the only answer at this point . . and yes it trips Knox . . it is what it is . . Trust me, you're not the first or only person to lament about the situation. I've been up on my own soap box many times too.
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] globalsearch:
ah..

I had a premonition, considering how no one touched my question. You can get a lot of answers by just by asking the right question, even when they don't answer.

As long as Android remains attached to this childish, closed sandbox and its restrictions, then its days are numbered. From the standpoint of a business owner, if I was a major company with product in the pipeline that needs something to run as the basic operating system, I WOULD BE LOOKING SOMEPLACE ELSE.

Google is not the end-all be-all of software. There were other operating systems before them and there will be operating systems after they move into the dustbin of history. I hope they are paying attention here. I personally have been in the field since the mid-70's, I see a strong pattern here.

Anyway, thank you for flipping on the light bulb. I will contain my rage and re-direct it to something more productive (like those dweebs at Papyrus - jesus)
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Sterist:
I was searching the forum looking for an answer to something like this... I have to say, I'm also shocked there have no answers given

regarding Knox... no you cannot restore that under any circumstances.

snapshot of everything else... yes and no. you cannot snapshot (aka nandroid aka twrp backup) your bootloader or STOCK recovery.

bootloader: you can only change this via Odin or OTA updates, and depending on the specific update cannot downgrade these below a certain point of the currently installed (if at all)

recovery:

you can freely flash new versions without a pc, but you cannot backup the stock recovery in a nandroid because the nandroid is generated using twrp -- a custom recovery that takes the place of stock recovery (mostly useless). if you find a copy of the stock recovery on the forum, you could then flash it back using Flashify from Google Play, but you'd then lose the ability to restore your nandroid until TWRP is restored.

also, you cannot take OTA updates while TWRP is installed, and in some cases at all / ever again after installing TWRP or root.

edit:

I can confirm that OF4 (the initial lollipop update) can be downgraded to NK1 (the newest kitkat update). if anyone can confirm for me whether or not OI1 can be downgraded to kitkat NK1 I would greatly appreciate it!
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Beut:
Depending on what version of Note Pro you have, LTE versions have locked bootloader, so they cannot downgrade.

Wifi Note Pro doesn't have locked bootloader, but downgrade from Lollipop to Kitkat you need bootloader for Kitkat along with the firmware NK1. If you read the threat LogicTech keyboard not working after update to Lollipop, you will see the link to Kitkat bootloader.

Without this bootloader, your tablet will hang at boot up after you flash the Kitkat firmware.

http://xdaforums.com/showpost.php?p=62371717&postcount=125

This is my current Lollipop OI1

[IMG="Lollipop"]http://www.mediafire.com/convkey/a136/9a3j8r608jlc94f6g.jpg[/IMG]

I downgrade it to NK1, this process only takes 5 minutes

[IMG="Kitkat"]http://www.mediafire.com/convkey/e867/7k88a8jb04usmbz6g.jpg[/IMG]

I did it only for demonstration but personally I think Lollipop has a better graphic interface, then I go back to Lollipop .

I can go back and forth from Kitkat to Lollipop with ease as long as right bootloader is loaded.

Since I loaded the OH2, the tablet is updating now to OI1 and it's wifi version SM-P900 Note.

[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] ShadowLea:
That's not entirely true. ;)

The USA LTE versions have a locked bootloader.

The International P905, however, does not. (Device-locking of any kind is illegal under EU law.)

Now, whether you can downgrade the P905 I really can't say, because mine has been comfortably sitting on 4.4.2, and I have no desire to let Lollipop anywhere near it. :laugh: Just thought I'd clarify that the US and EU devices are not the same :)
[Galaxy Note Pro 12.2 Q&A, Help & Troubleshooting] Beut:
If you can post your tablet with back cover removed, I can tell if it's different from US device. I once opened a tablet sold in England, I did not see any differences from US device except the hardware code indicates it's not from US. I swap a mainboard from SM-P907A, an LTE tablet from AT&T to SM-P905V, an LTE tablet from Verizon, it runs normally except the software customized for AT&T. I don't change anything from the Verizon tablet, except the mainboard from AT&T.

Even with a LTE mainboard, I can use any part of a Wifi Note Pro SM-P900 except the rear camera as they are exactly the same.

Or I can change a LTE Note Pro to a Wifi Note Pro by swapping the mainboard and rear camera, the rest are identical.

From my experiences of varieties of Samsung tablets, I don't see any major differences of Note Pro LTE and Wifi versions as they almost use the same parts.

By using a mainboard of Tab Pro in a Note Pro tablet, I can even change a Note Pro to a Tab Pro as they are using the same parts except the Tab Pro mainboard doesn't have S Pen cable connector, it works normally as a Tab Pro.

That means I can downgrade a LTE Note Pro to Wifi Note Pro or Wifi Tab Pro by only swapping mainboard and rear camera.

Given the fact that LTE tablets sold in US have different names but actually they are Identical , I can tell Samsung makes the same tablet but the differences

are software and firmware loaded into it, like SM-P905A, SM-P907V, SM-P907T, they're branded by LTE providers but the hardwares are the same
[G Pad 8.3 Q&A, Help & Troubleshooting] Wolfeman0101:
Hello,

I've seen a lot of people complain about the screen brightness but the X8.3 seems to be bright enough but the auto-brightness is just too low. It's like it is calibrated wrong and I have to switch it to 50% manually or it's just too dark. Any tips on how to fix it?
[G Pad 8.3 Q&A, Help & Troubleshooting] player911:
I noticed mine is real dark too. I have a nexus 7 2013 which is the brightest. It has a really red hue to mine too. I played around with a temp app and had blue turned up to 33% and green to 20% to make the whites look normal, but it makes all the other elements look a little out of place. Still looked worlds better but the app always had to run and I think just put a transparent layer over everything which caused missed touches and unresponsiveness.

A kernel level app would be much better to adjust the actual levels. The LG x8.3 was still the darkest device I owned. The G4 and GPad 7 both looked better.

I am half tempted to replace it because it looks so crappy compared to its G4 companion.
[E 2015 General] squid2:
I just discovered a very nifty little system and application profiling app called Trepn made by Qualcomm. You'll find it on the Play Store. I used it to examine the idle and low load CPU behaviour on several phones and ROMs. I was quite shocked by how terrible the CPU governor and hotplug behaviour is on stock Motorola ROMs (with the default interactive governor and mpdecision etc.)

On the Surnia stock 5.1 ROM, with the mild periodic load of the profiler (and no other apps running), all four cores were simultaneously staying above 1 GHz most of the time. The average (normalized) CPU load was only 14% when running the profiler. Switching from interactive to the ondemand governor improved things a bit (two CPUs at full speed, two at idle), but it was still pretty silly. These results probably explain why my phone gets so hot after half an hour of navigation with google maps. Google maps navigation is not that intensive, but the governor keeps all four CPUs maxed out at full speed, burning through battery and generating excessive heat for a moderate load.

I highly recommend curious users to try running Trepn on their own devices. Be aware that the profiler has some overhead and causes the CPU to work a bit harder than when at idle. For low overhead profiling of idle behaviour, I recommend going into the Trepn Advanced Mode and just running "Profile System" without showing real time graphs. Run it for 30+ seconds, then click on the stats button and look at the average results. For profiling medium/light loads, try the "Performance Graph" mode from the list of preset profilers. For profiling other heavier things, you can run the app in the background and also display overhead graphs if you'd like.

Anyways, in light of this appalling behaviour of the stock kernel/ROMs governor and hotplug, I've been inspired to work on addressing this battery waste and unnecessary heat generation. I might incorporate some existing custom hotplug and governor things in my kernels, or I might build my own governor+hotplug+thermal throttling system. Actually, I'm tempted to do the latter because it sounds more fun and I have a bunch of ideas floating around my head.
[E 2015 General] Ace42:
Why are you shocked? Stock Mpdecision has always been poor, hence the alternatives such as intelli plug, alucard, msm, and so on. Also interactive seems to be popular with stock kernels, but the scaling is extremely aggressive with no bias for battery.

Sent from my XT1528
[E 2015 General] squid2:
The stock surnia ROM actually doesn't even use mpdecision (it is commented out in the init scripts). I was shocked that Motorola would let such an inefficient configuration go by. I suppose that the battery was big enough for them to not notice the waste.

Interestingly, my 2014 Moto X is also running a fairly inefficient configuration (4 CPUs active all the time, with three at 1.2 GHz and one at 2.5 GHz when idle). The 2014 Moto X does have a small battery and would benefit greatly from optimization.

Anyway, I ended up accomplishing a lot more than I expected this evening. I actually created a new governor (based off conservative) that I called "Lionfish." My new governor combines the conservative approach with a a go_hispeed_load type feature for better responsiveness, and features more aggressive frequency reduction when the load goes down. I've been testing my new governor and I'm very pleased with the results.

I also incorporated faux123's intelliplug into my kernel, and it too is helping a lot.

I hope to release my new (and greatly improved) kernel in the next week or two.

Ever thought about making a cm kernel? Love your work with stock!

Hi I am currently using a d855 running Cloudy 2.5 with CTT 75 mod.. Mostly using my phone for playing emulators of retro consoles.. Should I have gabriel kernel installed instead of the CTT mod or both ?. Basically looking for a setup or some tips that will give my retro emulation the best performance possible on the G3 without overheating the phone. Thanks for any suggestions.
[G3 Q&A, Help & Troubleshooting] tunichi01:
Go for it

If you're on stock kernel then definitely give Gabriel kernel a try. I'm also on Cloudy 2.5 but without CTT Mod tho you can use Gabriel kernel with it. And there's also a flashable zip to fix bootloop (just in case) for those who have CTT Mod installed.

Performance were noticeably improved when I play GT Racing 2 unlike when I was still on stock kernel. I'm currently using 'Bumblebee' settings provided by

horsetastic

for Gabriel kernel. There's ton of settings so go check them out and see which one suits your needs:

Hello, this is herna from XDA Assist.

I´m sorry for what you faced with your device, but this is the main problem about buying and using clone devices. I can´t help with that since there a ton of clones and most of clones use to be very poor devices.

My suggestion is you to try to reach whoever sent you the device or the company which created it, or try to search on Google for someone who also has the device.

As a personal suggestion, if you are out of money, next time you buy a device, and wanna custom it and play with it like you tried with your device, try to reach some Motorola or "most famous" device, where you will have a bigger development under it, and you will have solutions for almost all the troubles.

I wish you get back your device on working, and also wish you to spend a nice weekend.

Hi,

The Bluetooth A2DP stuttering bug on Lollipop is unacceptable, and I have heard that KitKat users did not have the same problem.

Is there a compatible KitKat 4.4.4 factory image that I can use to downgrade my XT1072?

I believe the XT1072 (Moto G 2nd Generation with 4G LTE) has never been factory loaded with KitKat Android. Is there another Moto G model that has been, whose KitKat image is compatible with an XT1072?

Cheers,

Sunkai.

You are right. My understanding of the situation is better now, and I realise that there probably is not a KitKat or CM11 image that I can use with a Thea device.

I posted in this forum, as I thought there may be a different set of eyes on it than the Moto G 2015 forum, and that there may have been a Titan image that was known to be compatible.
