4.2.2 upgrade for AT&T GN8

So I'm starting to get a bit frustrated that I'm sitting here with the i467 and have heard nothing on any upgrades. The screen freezing is getting tiring and without an unlocked bootloader, there is no ROMs for us to upgrade to and none in development. At least we have root, but that hasn't solved our screen freezing issue.
So, my question is, does anyone have a clue on when we can expect an upgrade to 4.2.2 or maybe even 4.3? I have been searching and Googling and haven't seen a word.
Am I the only frustrated one here? Sorry to vent.

There is nothing wrong with venting. Unfortunately things are what they are. Products that are not used by a lot of users (i.e., GN8 for AT&T) don't draw too much interest from developers for obvious reasons. And you are at the mercy of AT&T for ROM update (even though Samsung develops the code).
After learning from my experience with Verizon (for Galaxy 7.7), I decided to stay away from carrier-based tablets. Battery life is better and you could use any product specific ROM developed by Samsung. For network access in non-wifi zone, I use Verizon mifi.
Sorry but you will have to wait for your ROM. Hopefully it is around the corner.

I agree completely. Next time I'm going Nexus for my LTE tablet. Unfortunately they haven't been available with LTE and we're likely only getting the 10.1 version next.

Finally signed up just to post my views.
Getting frustrated as well with the screen freezing, I too have searched for answers and have found nothing. We are certainly stuck waiting on ATT at this point. Is there anyway to complain to ATT or Samsung? What a crock of crap that this is still happening months after release.

Complaining is useless. All I can say is that it does eventually happen. Usually 3-4 months after Samsung releases it.

I get it that complaining is useless. What I was hoping was for any info that anyone might have on any possible update. Regarding your comment, does "it" refer to the wifi version? If that's the case, the if we say that 4.2.2 was released around August, that puts our version at Nov/Dec or so?
At Royaltiger, I remember you from the 7.7 boards. I also have the 7.7 (still have it, my wife uses it). I would love to go MiFi, but I appreciate having data built into the device. I could tether from my phone too, but sometimes I'm on a call and need data on the side. In any case, I agree with you and wish I could take myself out of the carrier versions, but there are always tradeoffs.
At dmunjal, I looked at N7 but like the 8" screen much better plus the Note capabilities. I take notes on my device all of the time. In any case, there are always 2 sides to everything. I just wish that we had more info from AT&T.

Ohh....I thought 4.2.2 upgrade for AT&T GN8 already out? no?
is this LTE version? what's your model number N5XXXX?

[Q] To Unlock/S-Off/Root or not

Just as a preface, wasn't sure if this should go in this section or the general section, but figured since this was Q&A I'd pick here. Anyways, I just got my HTC One today and am coming from Samsung Galaxy S3 (droid 3 and OG before that) and had them all rooted with custom roms, but have been reading about the process to unlock/root/s-off this device. I downloaded rumrunner and tried to run the program once already and got a "........f******" error and it closed without working, but that's not what I'm making the thread for. I'm really terrified of messing up the phone because I'm broke and can't afford to pay the insurance deductible if I break it and have to claim it was stolen. All of this back story to ask the question of: Is this one of those phones that NEEDS to be rooted to be worth using or can I expect acceptable battery life, speed, & use by simply disabling as much bloatware as possible and keeping the phone stock? Thank you for your advice, I appreciate it!

Honestly, based on what you wrote I'd say just disable the apps you don't want showing up and call it good. The Sense based ROMs are actually quite nice and HTC has been good about timely updates. Turning things off like Facebook notifications, weather updates, location service, and Google Now if you don't need it will all help. Enjoy your new phone.

I agree with mmuzy. I got my One right after they blocked HTCDev on this phone and the phone it worked perfect with out root. Speed was good, battery life was ok considering the size of the battery. My only reason for being hell bent on rooting this phone was ads on YouTube lol Pretty sure you already know this but disabling the animations in the developer settings speeds up the phone just a tad as well.

First things first, with the latest 4.3 update rumrunner doesn't work so even if you wanted to root and s-off it wouldn't be possible yet. Second, unlike Samsung devices, this thing is buttery smooth with or without the bloat so honestly your experience will still be excellent either way. I had an S4 before this phone that was rooted, all bloat removed, ad blocking, greenify, etc and I can tell you right now that right out of the box the HTC One was STILL way smoother than the S4 with NOTHING done to it. I'm running BoneStock at the moment which is basically just a stock rom, so I think HTC did an excellent job with Sense 5 on this phone.

I'm not going to try to sway you one way or another, just sharing my story. I've had the VZW HTC One since launch (Aug 22nd) and never saw a need to root or unlock it out the box. Everything was running great, the phone was smooth.
Suddenly, the 4.3 update arrived and my previously (close to) perfect phone has been plagued by issues. Multiple FCs from core and basic apps, piss poor data connectivity, and worst of all, terrible battery. Since accepting the update, my phone radio has been sucking roughly 45-60% battery at all time. Now I'm growing desperate for a way to unlock my device and control it. I went from around 14-16 hours of medium to heavy usage to barely getting 8 hours from light use. Once again, this is only my story, but, I know that having more control over my device will give me the ability to change my radio and fix my issues. So I vote yay to unlock/root.

Try a factory reset. I was running the 4.3 OTA rom for a few days and I didn't experience any of the issues you just mentioned. I'm now on 4.3 BoneStock with zero issues as well.

I agree with this. OTAs are nice in that we don't lose all our apps and settings but they're kind of like dirty flashing a custom ROM. If you have a gremlin infestation with the OTA then I'd start with a factory reset and see if things run better when you clean install your apps.

Well, after a few days of time to test after the full wipe and manual restore I'm still experiencing terrible battery life. As I stated before, it was mainly phone radio taking the brunt of the battery, and that still seems to be the case. On the positive side of things, I do have twice the free space available now.

[Q] Should I get the Note 3?

My Jump! just came up yesterday but was too busy to go swap my device. The only real decent phone that catches my eye and criteria, being it must have an sd slot, is the Note3.
Now I have a few questions regarding this. I currently have the s3 and it's rooted; will I need to unroot and triangleaway before taking it in? I've read some reports that tmo wont care if it's rooted and I don't remember where to find the t999L unroot method.
Furthermore, should I be worried about this KNOX thing? I love flashing and trying new things, because over time I get bored with the same setup. I dont plan to ever go through samsung for replacements as that's why I have tmo insurance and warranties.
from what I've seen, this KNOX thing is just a new problem attracting attention to samsung as most US based phones deal with carriers as far as returns and exchanges, not the actual company. Not to mention android itself is open source.

Short answer. Yes. Best phone I've ever owned.

ty for the replies guys. Should I just wait a month or two before rooting? I played with the handset instore for a little and it doesn't feel like it needs rooting right away.
I'm concerned about KNOX. I don't think I'll have to do any warranty exchanges, but it's better to be safe than sorry.
I'm far too lazy to unroot my s3, so I'm just gonna try and swap it while it's still rooted. if they give me problems I'll just unroot it then take it to another store

I'd wait to root. The phone is so much fun, as it is. And the whole Knox thing is a bother worth avoiding, for now. I could see it being worth rooting if there were reliable KitKat roms with TouchWiz. But there aren't. So why bother, for now?

For me rooting is about debloating the phone. Either by removing bloat or (as i have done with the Note 3) just freeze them for now. This gets a very noticeable increase in battery life. Also some mods can be nice. I like a very clean ROM with optimizations to battery and UI. The Kernel can be optimized too but like a stock kernel usually.
I'm coming from the VZW S4 running CleanROM and Bonestock but right now on the Note 3 I'm Rooted on Stock, with Bloat frozen and getting 7-10% battery drain per hour of screen on time (at 35% brightness) depending on what I'm doing.

i am curious how people like this phone, especially compared to the Note 2 and Galaxy S4. i thought the Note 2 was probably my favorite ever, the stock UI was smooth and battery life was excellent. i used the S4 briefly and found it a bit clunky and laggy with all those fancy features(although battery life seemed excellent).
so, how would you say the Note 3 is in these regards?

Phones awesome. Get it. No downsides whatsoever on this phone, sexy build, power, speed, removeable battery and SD card, great stock battery. Big ass sexy 1080 screen, what more do you really want or need from a phone?

My S4 was fine with the slightest of lag stock out of the box. I have the VZW variant from launch day (May 23rd) and i never took an OTA. With that said the 2 ROMs i used 100% wiped out any remaining lag. My S4 was pretty much perfect for me. The reason I am now on a Note 3 is i took advantage of Tmo paying off ETF. So why not upgrade to the Note 3 instead of making a lateral move?
That said, the Note 3 is AMAZING. It's much snappier and faster. I am Rooted with TWRP but stock ROM with just bloat frozen. It has better battery life and the spen functionality is really good. If you haven't you should really watch some YouTube vids to really see it in action. A 5 inch screen is most ideal but I have large hands so 5.7 is nicer for me as i do consume a lot of content (Youtube, SlingBox, Netflix). This wile still on the stock ROM too. I think anyone coming from the S4 or Note 2 will be very happy and would think of it as a worthy upgrade not a marginal one.

To the op question ~ I'm still torn between my Note 2 and this. The volume on this is so low that Samsung is practically begging you to root this phone just for that.
Tough call imo both are good. I believe you can still get the N2 pre 4.3 and not have to worry about Knox.
Software side its the small things that bug the hell out of me like having a white dialer and not being able to open internet pages in the background. Things like this that are enough to piss off the Pope!

I ended up getting it. I had to go back 3 times because my IMEI didn't reflect my account thru my warranty exchange. Went back today and handed in my s3 still rooted. The first 2 they actually checked if it booted, the 3rd just went ahead and did it. But to be fair he was there the other 2 times and was helping me then too. But they didn't go through any menus or anything to verify if modified or not. Just a 3 point inspection: No water damage, Boots, No cracks in the glass.
playing with it for a while..... Holy **** this thing is fast. I though I had stable quick roms on my s3... this thing just ZOOMS. I managed to lock it up once learning an spen feature, but only a mild hiccup. Aside from that I absolutely LOVE this phone. SO worth the minor 9$ bill increase. I can't wait to see what sammy drops for this. I'm surprised kitkat isn't an ota right now. I see no reason why it can't handle it.
Booted into download mode to see what was up. knox hasn't been tripped. I really want to try rooting just to see if I can debloat a little bit, but I'm a little worried to even mess with it. Do we know for sure if it's an eFuse or just software?

If all my reading is correct Root De La Vega will root without tripping Knox counter to 0x1.... it will stay 0x0 but the CF-auto root i think may trip Knox just with rooting. BUT... if you put any custom recovery on it like TWRP or CWM that will trip the Knox counter to 0x1. Knox is an eFuse, its hardware i believe the eFuse is in the Snapdragon 800 chip.

But do we know for sure? I've done a bit of reading too. And from what I've seen it's truly unknown. Even if so, would Sammy actually tear down that far to validate warranty claims?
Is this root method easily undone? Cuz all I really want to root for is my tibu and ad blockers. I'm content with stock atm

There is talk that it can be reset by Samsung, but nothing specific, I rooted via de la Vega and stayed stock to get some basic access without any issues. Very happy with the phone like it is and have no urge to try other roms.

I think Root De La Vega you're safe but not if you put a custom recovery on. just going to have to read through the post. and others can chime in if they did it that way. I put custom recovery on my phone right away so i just used CF-Auto root so i can't confirm from my experiences.

Should I Buy This Phone?

I'm getting ready to upgrade from my beloved Galaxy S4. I'm considering the One M9 and would love to hear opinions from current owners.
I saw another thread titled similarly, but that person didn't mention some of my chief concerns.
My biggest concern is I MUST have a rooted phone. The S4 was a bit of a pain because it was locked down so much, but the amazing people here on XDA always came through and eventually worked up root methods that idiots like me can follow. Other than the root issue, I have loved the S4.
My phone before the S4 was an HTC Incredible, which was awesome. And with a Verizon recently locking up the S6 with updates to block rooting, I thought HTC might be my ticket once again. Then when I came here to do some research, it seems Verizon has similarly locked down the One M9.
So how difficult is it to root the M9?
I saw something about sending the phone off to a gentleman who could unlock the bootloader. That would be an option for me since I don't have to have the phone immediately. If I do that, does that solve the root difficulty permanently?
On top of all that, how is the One M9 as a phone? Is Sense still similar to previous versions, etc.?
I'd love to read your thoughts!

Well, first of all, this question has been asked several times here and there are a handful of responsive threads that answer some of your questions.
1. It's very easy to root the M9, if you have access to one of the individuals in the java card thread. I drove a few miles west on the PA turnpike to hook-up with @dottat after acquiring my M9 and had a rooted, bootloader-unlocked handset within minutes of our meet-up. I had someone else waiting in the wings for me to mail it to him, but this was more convenient. If you aren't near anyone on that thread's map, you'll have to send the handset out. Yes, that's harder than the "gool ol' days" with many of the exploits available on xda and elsewhere, but that's life now.
2. As a phone it's great. If you happen to get another call from someone else with advance calling it is to telephone audio what FM is to AM.
3. The camera is very good. No OIS, but with 21 megapixels, it's pretty darn good. The front facing camera, an ultrapixel camera, is excellent for selfies, if you're into that sort of thing (I'm most assuredly not).
4. The processing speed is very quick with the multi-core processor.
5. Sense 7 is much more unobtrusive than prior Sense versions. I like it very much. I had even flashed a Sense 7 ROM on my M8 because I preferred it to Sense 6.
6. The device can get hot, especially in a sunlit care when dashboard mounted with BT audio and GPS in use. Very hot. The solution is run it naked and on a charger, otherwise your battery will die before you arrive anywhere. Overheating is less prevalent out of sunlight.
Hope that helps.

Just How Hot?
Thanks for the great feedback! I didn't know about the heat issue.
Here's another question: I use my phone at LOT for tethering. I keep it plugged in because the battery drain is so intense while doing so, but if the screen is on for any amount of time even the S4 gets HOT to the point of shutting down.
I'm not saying that's a flaw in the phone ... that's a lot of computing/work for such a small device, but ... do you think the M9 would be unworkable for my intense tethering?

I don't think tethering alone would do. Direct sunshine and GPS seem to be the main drivers

The heat is a luck of the draw thing too. My phone is caseless mounted to the dash and charging any time I'm driving. At a minimum it is playing music and has the GPS active. A lot of times it is running waze/google maps or Ingress. While it will get hot to the touch, I have never seen the actual overheat warning. I think the highest I've seen is ~118°F battery temp. I don't usually check the CPU temp.

Took the Plunge
Thanks again for the feedback, guys. I went ahead and ordered an M9 last night.
Will be sending it off to get bootloader unlocked as soon as it arrives.
Don't know what I'd do without XDA!

How to get firmware to increase my Note 4 battery life...?

Ok, " there's a disturbance in the force" :silly: so I am new to the world of phone hacks, tips, tricks, and repairs. I am pretty good with PC's and Laptops but phones are a new venture. I currently own a Galaxy Note 4 from AT&T. It is mine I have full admin access to all features etc... It has never been rooted or switched roms. I had a note 4 about 2 years back and noticed the battery started dying very quickly. I thought it was just the batteries time to go. So I just upgraded and got rid of it. After feeling nostalgic, I got another one and sure as rain, it was draining fast. I bought another battery even bigger Mah. and still fast drain. My father who works for AT&T advised me that there was a patch or update secretly sent out by Samsung that causes this problem due to their exploding battery issue to avoid any more law suits. My father also informed me that if I brought my firmware back to KIT-KAT 4.4.2 and disabled ATT or Samsung updates that this will restore the batteries longevity. I need to know how to do this. I have looked on XDA for answers but I find only parts and they seem unclear or incomplete for what I am trying to do. Is there a way to do this? if so how? please understand I am no phone guru. but if the instructions are clear to follow I can most certainly get this done. I'd like to thank everyone who has read this, and special thanks in advance to the person able to provide the information I need.

Have you checked to see if there apps that are draining your batteries more than the others?
Also, since your father works for ATT, would there be a chance to ask for the bootloader unlock for the N910A? That way, we can use custom ROMs and kernels which might provide us with the solution for lengthening the battery life and improving the performance of our device!

Thank you for the reply. I got this bone stock. I have added no extra apps onto it. I have even removed and or shut off apps that I will not be using. I have also dimmed the display, etc... as far as unlocking the bootloader info. The only information he was able to pull up is the newest Droid version. He doesn't have access to anything else their systems for employees are basically hyperlinks for problem-solving network and simple issues. he is the one who directed me here. sorry, i couldn't help with that. Moreover, he has to be careful what he does. He is not supposed to help friends or family with any services or he gets terminated..!!! This is what I have gathered from scowering the internet. back all my files up EFS File most important. Then use odin to flash the 4.4.2 kit-kat firmware. then block all samsung or att updates. blocking the updates I do not know how to do. flashing the firmware I can do!!!

If your phone is running Android 5.1.1 or or newer, then I don't think it can be downgraded to KitKat. It would probably be better for you to just try to figure out what is draining your battery. Check the battery information in settings, or if you want more detail then get get GSAM Battery Monitor or Better Battery Stats in the Play store.
