[LG G Flex 2] yellowman82:
Well that's great news for you but you and a couple of other's that are supposedly not seeing the lag anymore or what not doesn't mean it doesn't exist. It's all over the internet worldwide and some here on XDA that received this update is still seeing these issues with lag and throttle/heating up on their device. Either both LG and Qualcomm really screwed up on this device it's not only LG because even there's news of the M9 having this throttle/heating issue so Qualcomm is also to blame.
[LG G Flex 2] bmoses:
with regards to overheating, i've found that using the radios is what makes my phone get warm/hot the most. I can play a game or do any other number of things for hours on end and the phone barely gets warm. But as soon as i start using any kind of data, like doing app updates or speed tests or streaming videos, thats when the phone starts to get warm and starts lowering the screen brightness due to temperature increase. it doesn't matter if its 3G, LTE, or WIFI, using data over any of those connections causes the most heat in my phone. i'm on my 4th phone and its been like that on all of them.
[LG G Flex 2] theveterans:
My HTC One M9 does not heat after the software update. It does throttle, but not as bad as the flex 2 where benchmarks are below Snapdragon 800 Level. On the contrary, running multiple consecutive benchmarks on AuTuTu, phone can still score consistent 55000 - 61000. Geekbench 3 also scores 1100-1350 single core and 4000 - 4450 multi core.

I like both phones, but LG skin is really laggy especially when you are used to the M8/M9.
[LG G Flex 2] force70:
Thats like having a ferrari and not being able to take it out of 2nd gear.

What an absolute waste of what should have been an amazing device.

[LG G Flex 2] robdevil:
Now I do. Its Nexus 6 and is lightning fast. whoopie!!! Just bit too big :)

Worst was browsing internet on chrome. Phone just freeze and I could not do anything just restart. No more LG...until G4 ^^

Seriously G Flex 2 is one of the most beautiful phones now but I cant believe how slow it is.
[LG G Flex 2] kranthirebel:
How to unlock bootloader. And when and how will lg g flex 2 bootloader gets unlocked. Lg g2 and g3 has many roms. I need for my lg g flex 2 also. I want twrp custom recovery and nice roms for lg g flex 2.
[LG G Flex 2] robdevil:
Fck. 2nd buyer returned this piece of ... Aaaaarrrggggghhhhhhh I hate this lag!!!!
[LG G Flex 2] yellowman82:
As for now there's no way to unlock the bootloader and I feel bad for a lot of you guys that purchased this phone instead of waiting. I had the first G Flex and the bootloader was never unlocked there really wasn't no kind of development on that device.

Not trying to be so negative but the way things are going for this device it seems like most likely it's going to be like the first G flex and never have the bootloader unlock and if it does it might be in couple of months and reason is well this phone has a bad reputation already just to start it of and well since the G4 is coming out or unless it's out already and I didn't noticed, a lot of these devs are quite going to skip the flex 2 and jump on the G4 especially if the G4 808 chip doesn't have any issue at all out the box but hey I could be wrong but who knows that's just me guessing.
[LG G Flex 2] probaina:
It seems like no one with the 3GB version is experiencing lag so I assume this has something to do with the Rom and bad memory management. Or perhaps the 2GB version doesn't have the same thermal pad as the the AT&T model. I don't know since I only own the AT&T version.
[LG G Flex 2] Intub8:
Yes and let's not forget android 5.0 has a pretty bad memory leak problem. Hopefully 5.1 fixes that.
[LG G Flex 2] Kidsnd274:
I bought the 32 GB version, yet my phone came with only 2GB of RAM. Must be a carrier version. I thought I could work with 2GB of RAM, but when the LG UI and android already takes up ~700MB, its not easy to deal with.

I really do hope 5.1 fixes all the problems. My carrier doesn't allow returns
[LG G Flex 2] BillyxAllen:
Funny story. I was dicking around in the phone and deleted LGs home screen by accident. The only user interface on the device is Nova. I tried installing the apk for LGs ui but it refused to. Seems snappier though. Not sure what I did tbh. BTW disabling cores 4 and 7 have my battery lasting about 2 days on a single charge with standard use.
[LG G Flex 2] Ronee33:
I think the battery life wariates according to the firmware wersion. Earlier I got less then 12 hours with lag and overheating. Now with updated firmware I got 20 hours. Still
[LG G Flex 2] mkiller88:
I have manage to reduce some lag by selecting in Dev Options to allow maximum 4 background proceses and animations scalling set to off. I hope this will improve also my battery life, as the firmware i have v10c, the phone dose not find a newer firmware version.
[LG G Flex 2] Ronee33:
You can update manually to v10e for EU versions.
[LG G Flex 2] mkiller88:
I will lose my warranty? I also dont have root.
[LG G Flex 2] probaina:
Like others are saying here I think this is a memory management issue with Lollipop. When I had CM12 Lollipop 5.01 on my Galaxy S4 with 2GB of ram it used to lag like crazy after opening a few apps, sometimes to the point of freezing. Someone in the forums suggested to install Greenify app from the playstore which will auto hibernate apps that you choose so they don't keep taking resources while running in the background. This fix a lot of the lag issues I had with my GS4 on CM12. Maybe someone can see if it helps your device here. Once I upgraded my GS4 to CM12 Lollipop 5.1 all the lag issues I had before were gone.
[LG G Flex 2] mkiller88:
http://www.androidpit.com/lg-confirms-the-snapdragon-810-has-battery-problems - Nice!
[LG G Flex 2] Ronee33:
You don't need toot and won't loose warranty. The process is with an official LG tool.

Check for how to manually update LG G3 and you will see what I mean. The process is the same. Just use the correct software wersion for your phone.
[LG G Flex 2] drmilosh:
Well, I read almost all the comments and have to say.. I dont have any issues with g flex 2. It works excellent , no lag whatsoever etc.. Just hopping we can update to 5.1 because of battery drain, but then again, my phone lasts 14h + and I play WOT Blitz sometimes..
[LG G Flex 2] another_smith:
I'm about ready to give in with my lg flex2 and go back to my htc m7. the flex is pretty much unuseable for me
[LG G Flex 2] lowther_hall:
I'm having all of the same problems, and I don't want to lose my warranty from rooting, I'm just twiddling my thumbs for 5.1....anyone have an ETA for the Sprint variant?. it says the Flex 2 to has 5.1 on GSM arena.
[LG G Flex 2] jodeelee:
Just a quick update. I got my 959 with 10b firmware and i updated 10c and 10d. Lagged like crazy. Sent it to the service center and all they did was reflash 10d. Its perfect now. So maybe the incremental update killed it. Maybe everyone should do a reflash 10d
[LG G Flex 2] eallan:
What would rooting help?
[LG G Flex 2] lowther_hall:
For xsposed, or an app to quick the cores
[LG G Flex 2] lowther_hall:
Hell yeahh! Sprints rolling out 5.1 for flex 2 now! Very excited to see if this will fix the memory leak! I'll report back if I see any difference in the lag.
[LG G Flex 2] soosoolhastam:
Disable all the at&t bloatware and you'll no longer have battery issues.

I figured it out after doing before and after tests for a week
[LG G Flex 2] soosoolhastam:
changing thermal settings (http://xdaforums.com/g-flex2/general/thermal-throttling-hotplug-settings-t3106165)

changing kernel i/o scheduler to row

worked wonders for me
[LG G Flex 2] lowther_hall:
Wow, I've finally got the update....and I just have to say what a difference its made....everything overall is just snappier, quicker and smoother. Thank god for this 5.1.1 update.
[One (M8) Q&A, Help & Troubleshooting] dbarrett480:
I have an unlocked bootloader but not s-off am I still able to flash custom roms? if so how do I know which ones I can flash?
[One (M8) Q&A, Help & Troubleshooting] dbarrett480:
Does the old trick of booting to recovery via fastboot still work? I haven't had an HTC phone for a while....
[One (M8) Q&A, Help & Troubleshooting] xunholyx:
Yes you can flash any ROM while S-On. S-Off is not needed for that.

And yes, you can get to recovery via your bootloader. But once you have a custom ROM, the option to boot to recovery will be available when you long press power.
[One (M8) Q&A, Help & Troubleshooting] EddyOS:
S-OFF only really comes handy as you can flash different FW packages that aren't signed by HTC, or downgrade to an older FW package if required/wanted
[One (M8) Q&A, Help & Troubleshooting] TempestZ:
Correct me if I am wrong, but from what I understand you can't flash a kernel with S-ON right?
[One (M8) Q&A, Help & Troubleshooting] xtcislove:
Wrong

U can flash following partitions

system

boot

data

recovery
[One (M8) Q&A, Help & Troubleshooting] EddyOS:
That was the case with the One X a few years back but changed since...

Notes

Disclaimer

These notes are old and do not apply to recent builds.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------​

Side Notes:

I initially made these builds to test some work I am doing with the proprietary apps on the Portable. But since no one else has released cm builds for the tablet, I figured I might as well. Unjustified Dev did the vast majority of the work on the kernel and device tree. I only did a bit of work to enable the modem. Attached are the two patches I made to the framework to allow controller pairing to work. Also attached is a flashable zip of the proprietary apps. Do note that these do not work as intended and should not be used with great expectations. The controller will pair and seems to work indefinitely (unlike on the Portable), but audio is always forwarded to the headphone jack on the controller regardless of something being plugged in. The Shield Hub can be installed, but the Grid section is not even available as a selection (again, unlike the Portable, which gets into the grid stuff but segfaults mediaserver). If anyone has reverse engineering or research skills, help would be much appreciated in smoothing out the problems here.

The North American LTE build is reported to work as expected on the Rest of World LTE model. I have not finished research on what all the stock build differences are. But it should be safe to use the build on either model.
[Shield Tablet Android Development] pjim:
Installing now, I'll let you know. I appreciate the build, I really think this tablet would benefit Cyanogenmod. But they all have locked up the touchscreen for me. Only comes back after reboot.
[Shield Tablet Android Development] FoxyDrew:
Really appreciate you putting this together. Can't wait to get CM on my Shield!
[Shield Tablet Android Development] pjim:
Let it boot up and just basic set up, very smooth and fluid, just like CM should be. I let it go to sleep a half dozen times and it woke right up, touchscreen and all. So far so good.
[Shield Tablet Android Development] danjull:
I'm still getting touch fail, but it's getting better. It took almost a day before it started. But after turning the screen off and on a few times it comes back. Haven't had to reboot yet.
[Shield Tablet Android Development] FoxyDrew:
But...but the ROM's only been up for 2 hours. It "took almost a day" isn't even possible. Unless I'm missing something, which must be the case haha.:confused:

ROM works just fine on the WiFi model, except for obvious (and obnoxious) data indicator in status bar, and mobile network options in settings, any way to just chop those out, maybe in a WiFi build? As like I said it works fine otherwise.
[Shield Tablet Android Development] Steel01:
I posted a link of a prior build to some of the other tablet devs yesterday, that's where he got it from.

Yes, this is a build for the North American LTE tablet since that is what I have. I can run off a build for wifi-only, but it will be tomorrow before I get to that. I eventually want to get a unified build of this that will enable the data stuff for the LTE model and hide it all on the wifi model. Shouldn't be terribly difficult, but that's further down the road.
[Shield Tablet Android Development] FoxyDrew:
Awesome to hear :D
[Shield Tablet Android Development] pjim:
The gps works, took a while for the first lock, but locks in seconds after that. Compass is 180° off, pointing north, indicates south
[Shield Tablet Android Development] Steel01:
Alright, here is the wifi only build. I have not tested flashing it since I don't have time right now. But the only difference between this and the lte build is marking it as wifi only and not including the modem libs. Also disregard the day difference in the filename between this and the lte build, it's the same code base. I'll link this in the first post if I get a couple positive comments on it working.
[Shield Tablet Android Development] FoxyDrew:
Just got it up and working an tested (doesn't work on MultiROM but I figured as much because Pac doesn't either) and everything seems to work 100% fine.

I've tried to get touch to break after deep sleep with no avail. So for now, for me, it's great! Touch responsiveness is great, and its performance seems to be on par if not better than stock, not that I could get stock to even studder at anything.
[Shield Tablet Android Development] matlear:
Does this ROM support HDMI out, Shield controller and the stylus?
[Shield Tablet Android Development] FoxyDrew:
The stylus and HDMI out I can confirm working. The controller I never bought because I owned a Moga PRO before buying the tablet, so you'll have to try that out yourself.
[Shield Tablet Android Development] Steel01:
It should work with multirom as long as you have the latest twrp and multirom. Bogdacutu posted those toward the end of his multirom thread. The official releases won't work.

The stylus works and seems accurate, but none of the specific apps are included and I don't know if the pressure sensitive part works. I haven't tried HDMI, but the report above says it works. Once other show stopping problems like the grid and controller stuff is worked out, I'll look into reimplementing console mode. Should be pretty easy. As mentioned in my second post, the controller pairs, but isn't completely working. Like it won't remember the pairing and you'll have to repair on every reconnect.
[Shield Tablet Android Development] FoxyDrew:
Yes, I was using the latest MultiROM with the latest TWRP.

Also WiFi often disconnects, and stays on "saved" until I reconnect it.
[Shield Tablet Android Development] BitOBSessiOn:
Great news!

Firs of all, thank you for sharing and the team work.

I'm newbie with Android roms but in the past I've compiled and tunned linux kernels (since Linux was 0.9...) I've been playing with cm12 and nvidia sources without success... I've too much to learn... ;)

I ask if this rom is suitable for wx_un_do model (RoW LTE). Anyway, I'm dowloading sources for playing (perhaps to adapt to wx_un_do if necessary and I'm able to...). I would like to help....

One more question... Is it necessary to add vendor directory from nvidia sources... ? How are proprietary (licensed) files managed in the source ?

Thnx a lot again for this work.

PS: Very interesting if we can count with nvidia apps in cm12... it would be the "perfect" scenario :good:

I think answer to myself about proprietary files...

Is this ok?

Thnx.
[Shield Tablet Android Development] Gilbot:
Flashed the LTE rom on my Wifi unit. I have been using it since last night and so far so good, no touchscreen issues yet!

Only issue is auto connecting WiFi. I am very happy to finally be rid of the stock ROM lag ☺
[Shield Tablet Android Development] grv00711:
nice... ..using SuperPichu's Custom Lollipop Kernel, Kernel for the Nvidia Shield Tablet with this rom no issues so far.!
[Shield Tablet Android Development] FoxyDrew:
Check the thread out, there is a build for WiFi model and it works great, Steel said he'll put it on the OP if he gets enough positive feedback!
[Shield Tablet Android Development] BitOBSessiOn:
I usually use TWRP 2.8.5.0 MultiROM patched, with no problem (not using MultiROM at the moment).
[Shield Tablet Android Development] C0BRA01:
Heres a link to the latest CWM in a post which is not linked in the OP, as that one is upside down, and some other issues I guess, Just tried this, and it appears to be working. http://xdaforums.com/showpost.php?p=57781401&postcount=130

The TWRP you are talking about, does it support formatting Boot? Multirom 31 = TWRP 2850?

Formatted boot, and all the other partitions from the latest CWM, and still does not work. I used the CM you uploaded yesterday, and the minimal GAPPS. :(
[Shield Tablet Android Development] BitOBSessiOn:
No, only system, dalvik, cache, data, internal and external.
[Shield Tablet Android Development] Pariahnoble:
[MENTION=5347975]Cobra01[/MENTION] use the cwm in the op on that thread. The right side up one had mounting issues on mine. I JUST got unbricked by dumb luck as I have no pc right now. The upside down one works flawless.

[MENTION=6411851]BitOBSessiOn[/MENTION] so far ur build on my wifi is great. It feels smoother with the better kernel. I'm gonna try to fiddle with some performance settings and see if they stick. The way I figure it. This is the fastest android I've ever held and really no games require the full horsepower of the shield so I'm trying to clock down the cpu, to get more batt life. If i had access to more settings in the cpu and power supply stuff I can tweak power and clock speeds to get us a goodly chunk more up time. I used to use synapse before back on the Galaxy Nexus but it this kernel doesn't support it... Anyway well done

Edit: still no lock screen deaths. Not once so far

[MENTION=6411851]BitOBSessiOn[/MENTION] very well done =)
[Shield Tablet Android Development] albertorodast2007:
Yup, romancer one is a no go. Hope Unjustified Dev updates it to 2.8.6.0 soon.
[Shield Tablet Android Development] Pariahnoble:
[MENTION=993053]albertorodast[/MENTION] as long as the new 5.1 doesnt require an update I doubt it. Far as I can tell it all works so far. But time will tell. Wish we had touch cwm. Tried twistedumbrellas philz touch cwm but it randomly black screens and I had to force reboot.
[Shield Tablet Android Development] albertorodast2007:
+1 on Pariahnoble, this ROM runs in circles around stock. I'll stop flashing like a crazy for a while and stick with it until cm12.1 is stable enough.
[Shield Tablet Android Development] BitOBSessiOn:
Thnx. Nice to hear you, partners... :) Anyway, all kudos to [MENTION=1416222]Steel01[/MENTION] and devs before him preparing the path to CM 12.x in our devices. I'm just learnig a bit and playing with kernel params by the way... ;)
[Shield Tablet Android Development] MiePx3:
Hey guys!

After testing a bit with multi rom I decided to replace stock with CM.

Should I update now or wait for CM12.1 if it gets released?

If not, will it be possible to update to 12.1 from 12 without wiping data again?
[Shield Tablet Android Development] Keithn:
No you want to wipe when changing versions.

Also speaking of cm12.1 I somehow got WiFi to connect. I tried a different kernel just to see how it would react and it FCed as expected. Then I flashed the cm zip again and wiped cache and somehow I could connect to WiFi. No idea why that would even begin to work but I'm trying to figure it out.

Sent from my One M8
[Shield Tablet Android Development] corvus:
I read later in this post that your cm12 version doesn't update boot.img? Maybe this can be the problem. I don't remenber wich version have before yours :D.

The correct way is official shield 2.2, the 2.2.1 and then cm12? or maybe I can tray with some of the custom kernels?.

Thanks for your help.
[Shield Tablet Android Development] C0BRA01:
I think you misread that. It was not CM12 not writing the boot image, it was TWRP not having the option to erase the boot image.
[Shield Tablet Android Development] corvus:
Oh, great....

So should I use CWM better that TRWP, or it has the same problem?
