I got the base rom to run pretty good once I turned off all notifications and animations, and set the max number of background processes to 4

I like los14.1... but I've barebones the build by deleting everything I don't want and then I added some tweaks to make it feel real good.

All the custom roms are more or less the same (except for stock based like stock+ rom) because they are all made from Steel01's sources baked with custom rom specific files. So pick the one you find the prettiest or the most useful...

Hi All
What is latest ROM , there is any stability one from end of 2018 . Maybe someone working on new one ?

It depends what you're going for on your tablet. If you're aiming to keep all the Nvidia specific features I would recommend the 5.4.1 stock+ rom. If you don't care about any of that I believe that lineage is the way to go. Between the two, performance is the same for the most part, lineage is based on 7.1.2 though instead of 7.0, so you get a few newer features. If I have time later to come back to this I'll link them.

I've been trying the 5.4.1+ rom. For some reason it crashes and boot loops after installing Swift Keyboard Damn, I really like that keyboard. Then I updated Magisk on it, to get a message saying the new Magisk app isn't supported. So I uninstalled it to download the previous version and that caused a bootloop now too
Just flashed it again, hopefully it works better this time.

I am also wondering what is the best ROM for my K1 is?
First off, I bought this tablet used. Did some research and found out about the battery recall, mine is not one of them, as in I have the newer/better battery.
Secondly I did update the stock rom to 5.4 but the battery drain was horrendous. No gaming, just surfing facebook or the internet was a draining the battery in a few hours. Even in standby on my nightstand, battery was almost dead the next morning. Then after some research many people said to downgrade to 5.2 which I did and it pretty much fixed the battery drain issue.
Then I found out about LineageOS and decided to install 15.1, performance is good, but does still experience some battery drain issues, but not as bad as 5.4.
I also know that earlier this year LineageOS has returned support for the Nividia Shield K1 tablet, but is that for OS 17 and how long do I have to wait for that version?
Any advice would be greatly appreciated.

On 5.4 to get regular battery usage you have to enable custom cpu profiles, the default profile doesn't idle properly and the cpu's stay in a higher frequency state. You can then have all 4 cores enabled and it will idle properly (well it does for me), and you have nvidia driver support for the original wifi game controller which i have.
Otherwise, if you use a LineageOS 14 build, you can have full hardware video acceleration, on 15 builds you won't have hardware video acceleration.

So what your saying is I can go back to 5.4 and just play with the settings? Any special apps to do this, or just all within the android settings that need changing in order to have the performance and stop the battery drain problem?
If it's just the android settings, what are the settings I need to change? Tutorial?
Thanks

AOSP extended from bit obsession is a bit old but still snappy!

honestly, i think we are all screwed
my tablet wont charge at all now. it shows the icon on the screen saying it is charging but it doesnt charge at all. sometimes i can get about 10% on it.
the computer no longer recognises the device and i have only ever used official ota firmwares for it
spoke to Nvidia and all i got was the out of warrenty response.
they no longer care in anyway about shield tablet users and as it is discontinued its not like you can even buy a replacement. you cant buy secondhand either because theyll all just have the same bollocks battery issues we have on ours now.

I'll contribute a data point for anyone reading in late-2019 going into 2020:
I'm on Stock+ 5.4.1 on my K1 and it has been great for me so far in the last few weeks since I flashed it. I had been on the stock Marshmallow firmware for the past three years and was having the typical lag issues on wake. It was so severe that the tablet was completely unusable coming out of a deep sleep. It was also a chore to reboot it because even the lag on holding down the power button was agonizing and unpredictable. It was worse than booting Windows with an old hard drive.
I've had no lag-on-wake issues with Stock+ 5.4.1 so far. It's like coming back to remember why I liked this tablet in the first place after hating it for the past couple of years. I hadn't used it for anything other than daily alarms over the past year and change, but lately, I've been using it for bedside reading again instead of my phones.
To address a few of the issues that have been brought up in this thread:
I haven't had any battery drain issues with Stock+ 5.4.1. It seems to do about the same on my K1 as Marshmallow did, which was 100% to 15% on idle except for daily alarms (and snoozes) from Sunday through Saturday.
I ordered a new 6000 mAh replacement battery from AliExpress and will be installing it when needed. My current battery life isn't great, but it's not horrible either. I think it still manages to have about 80% of its original capacity.
After installing Stock+ 5.4.1, I flashed the latest Magisk 20.1 zip (Stock+ 5.4.1 came with Magisk 16.0) from within TWRP at a later date with no issues. Magisk 18+ is not compatible with Magisk Manager versions older than 7.0.0, but the old versions of Magisk Manager were bad in that they would always ask you to update to the latest version regardless of what version of Magisk you had installed. Basically, Magisk Manager was asking you for permission to nuke itself.
I have never used the official Facebook or Messenger apps, but virtually every comment I've ever read about them say that they're battery killers. Use a third-party app that combines both and has a smaller memory footprint.
I used to be an avid user of SwiftKey, but I've since soured on it. I haven't installed it on my K1 since the firmware upgrade and I don't know if I will going forward. The biggest benefit of SwiftKey used to be the dedicated number row, but its predictive swiping was the worst I had ever used. I'm on Gboard now and it seems to be working well. The only feature I miss from SwiftKey is the arrow keys to move the text cursor.

I am also wondering what is the best ROM. I got a K1 used as well not too long ago, and I mostly want to use it as a study tool for some CompTIA certifications in 2020, so viewing PDF's/word docs, exam simulations, and tutorial videos will be it's primary function. I do like comics so I would like it to perform snappy.
I really have no interest in gaming or social media.

I went with a stock-based ROM because I still wanted all of the tablet's functionality to work as designed, even though I've never played games on my K1 using a controller or created an Nvidia account. However, as long as retaining those features won't cause the device to run poorly and there isn't anything inherently poor about the stock experience, I don't mind. Stock-based ROMs are usually easier to set up and install. Nvidia stock firmware isn't known for being particularly bloated or heavy like that of some phone manufacturers, but of course LineageOS is still going to be faster at the cost of some device-specific features.
Given your intended use, as long as you use something newer than the stock Marshmallow firmware and its wake lag issues, you probably don't need to worry about much else.

I decided to dig my K1 out of the closet and have a play with over the holidays. I just flashed the stock recovery 5.20 but for some reason I cannot update or download any apps from the Google Play Store. I keep getting error 963. I searched how to fix this but nothing has worked.
Anyone else been able to fix this?

HTC U Ultra no updates since Feb 2018... still safe for daily use?

I have a two years HTC U Ultra as a daily driver, battery duration and other minor annoyances aside, I am pretty happy and I don't feel the need of replacing it. What worries me more is the lack of updates for the last 18+ months, what makes me wonder if it is really safe to keep using it "as is". I know there are alternative custom ROMs, but I already walked this route with other devices and they just don't meet my needs, the overall user experience is worse and the unlocked bootloader gives me headaches with apps like netflix and others. What leads me to the question... is an Android device with 8.0 and no security updates since early 2018 still safe to use?
Thanks.

If it is safe? I think it still is, thinking about some who still use android 4.4 to 7. It has of course more exploitable holes in system, but it depends on what you visit online, what you download, apps you use, etc. I think that with the encryption, the stock could be safer than the custom ROMs. I am on Android Q and is not as stable as stock, the camera is also not so stable. I'm using it because this version has better battery life and speed than stock. But that's the story with almost all phones with custom ROM, an adventure .
It is a shame that HTC stopped the support for HTC U Ultra so fast, so we cannot have all.

android Q is better or 9.0 in terms of stability , camera , battery ?
and can we take any legal steps against htc to force them update the u ultra to the pie update as it has to do so as the device should have 2 years of updates , i think a legal case can be made against them

i like the stock too , specially in camera as other custom roms doesn't support the focus of camera and the laser autofocus , but now i have a strange bug that the device tries to launch something in a fraction of second and then it doesn't open it . so u see that strange empty pop up that makes the device really bad to use , did u face it ?

No, that didn't happen to me so far. The worst problem it has, after two years of use, the battery duration just sucks. It never was that good, not even new, but now I can't stay too far from a charger. I haven't had good experience with third-part replacement batteries in the past, so I am not replacing it for the moment.

[Discussion] my experience with custom roms in 2 years with this device

I am just telling my experience, all the Dev's are best, they are the ones who let me explore more in around android and it's versions.
I used custom roms on k5 plus 3gb for 2 years i think.
It was like first few months i used the original rom and then i voided the warranty with custom roms as i saw more possibility and newer versions of android coming better than what i had. I kept exploring every part of the phone, and whatever softwares i could use and get more from this phone. Few roms lasted around 4-5 months. I love the nougat roms still, there is a Android Q rom already here, amazing. It was a good experience, until this last few months i started to have battery drain faster when i would use the hotspot feature or use bluetooth for headsets, and gps was like the most battery drainer. I kept changing roms and seeing what would give more bettery life while using, the sleep/screenoff state uses like no energy and then opposite happen if i use in full brightness outside and gps
Then
today i just tried to see the stock rom backup is working or not, it did, and now i realise that the most stable rom is the stock rom that comes from lenovo. The battery life is just way better than any other roms (+1hour than what you get in current Oreo and pie roms), the performance is back, Dolby Atmos is back and works, the inbuilt vr works.
The apps which were quite heavy lagged in animations in custom roms, stock does it smoothly, and i didn't need to get a small gapps package for performance this time, stock has like most gapps i think and it's smooth.
New stuff like play protect, assistant, well-being, etc are now available for this old lollipop rom as well, most of the features in the future versions are now available to use with simple downloads and a few majisk modules, without harming performance.
i am not sure how secure the rom/os it self is with old security patches. But yeah original rom got to be top 5 in best rom/os available for this device in terms of overall usability in daily life.
Tell me what your experience has been, i will use the stock lenovo again now for sometime. And might get back to custom".:laugh::good:

just to add you could try the latest stock ROM our device got wich is MM, and tell us your experience. I'm on it since a lot of time, and I won't move from it anymore.
don't you know the link?
here it is:
https://drive.google.com/file/d/1OGx6L4kTsoH1e_RxIRA_S6shIEiRBqT9/view?usp=drivesdk
it's a TWRP backup made by a Brazilian user and posted here on xda long time ago.

quickly instructions?
here we go:
go to TWRP and restore only /boot and /system partitions. that's it.
You could share with us how did you feel it compared with LP.
PS: everything is working flawlessly for me. a6020l37 (sd616 2gb RAM single SIM)

Okay I will check this out, also you don't need to quote long messages

Lenovo stock ROM wasn't that bad but after installing Android 10 (AOSP) Custom ROM on my Vive K5 Plus, it's feels a relief.
Yes there are some minor issues & bugs but over all satisfactory experience.
Personally I will always stick with this ROM over Lenovo stock 5.1
Thanks.

Yes, I extended a bit, but not that much as you unnecessary long OP, just to say stock ROM is more battery saver than any custom ROM.
BTW learn that this kind of experiences sharing shouldn't be posted in the guides section.

Yep aosp 10 feels good.... I will use it when it gets a bit more updates

AOSP 10 has got another build. I guess the last possible build since Dev may be moving out of Vibe K5 Plus platform.
I have just upgraded to the new build & it's stable enough.
Yes although performance can't be called butter smooth but it's better than previous build & most of the phone features that I may need in daily usage are working fine.
Standby time is good but SoT is on lower side, but I can't blame the ROM, it's my battery which is very old & worn out by now.
Thanks. :fingers-crossed:

The best rom with extended battery life was AOSP extended. i used it for 2 years with Dolby atmos mode and it worked flawlessly. Stock rom eats up battery too fast.

Is Android 10 worth it?

Title says it all...is upgrading to Android Q worth it?
Currently running Sky Dragon ROM and the current build I believe is based off Android 9.0.13. I've been so pleased with it I haven't thought about flashing anything else until I saw we got a stable Android Q build.
I've read plenty of threads where users were having issues flashing and just GETTING to Android 10 on the 6t. Nevermind the issues I've seen with people who are on 10 with apps misbehaving, bugs, etc.
Just looking for honest mini reviews of the 6t's latest OOS experience before I embark on the journey of getting there.
So, those of you who have made the jump, is it really worth it?
Thanks in advance!
-Pain

There is no question of worth it or not, Pie support (security especially) is now dropped, you won't have a choice if you want to keep an up-to-date and secure device.
And problems reported only concern a minority a people. And now there is a fully working TWRP for A10.

I'd say it is worth it. There are many new features which make using the phone very convenient. I haven't faced any issues with the ROM itself, just some times magisk prompt won't appear when an app requests root. ROM is stable. Also installed radioactive kernel now its running even better. I clean flashed android 10, it is always better to clean flash such major updates.

In my experience, I have a stock T-Mobile variant, converted to international version. And updated to A10 and didn't last a week without wanting to revert back. All the bugs reported in other threads all happened to me. From random reboots (just twice happened), fingerprint animation staying on after unlock, some lag on the screen when scrolling, the loss of the Play store certification along with the GPay because of this. I just decided to revert back. Downloaded the full wipe downgrade which kind of soft bricked the phone but nothing the MSM tool wouldn't fix and now I'm back on 9.0.17. I'll just wait for a more stable release. For me at least I'd say it's not worth it yet...

I wanna say wait for the official OTA release. I see a lot of people are complaining about issues with the new update. But there are also people who are full satisfied with the update with no issues. If you are using your OP6T as a daily driver I would say wait for a week or two more to see if the new update drops officially and do that.

Definitely worth it. I've had one random slowdown (resolved with a reboot) and a single crash reboot where I got stuck on the boot animation and had to hard boot, but they're the only negatives. There's a bug with the haptic vibration on key presses being stuck on maximum, but the benefits are many - great battery life, apps open much faster, fingerprint reader and general UI responsiveness is much better.

For me it's worth it especially since the baked in swipe to go back into the os, I've been using 3rd party apps for that functionality since early days...

I think it is worth it specially once I figured out how to get root. I don't have twrp installed and not sure I need it. Battery is good and I really like the launcher. No need to install any themes at this point.
EDIT
Just flashed Twrp with Magisk works perfect.

Is it worth Jumping from Nougat to Pie

Im currently still on 7.1.1 Nougat with Oxygen version 4.5.xx
Its working stable and pretty good so far, have not encountered any issues (Other than occasional android system draining battery issue once every couple months which is solved by clearing cache.) Should i be upgrading to PIe?
The reason i did not upgrade was because i read a lot of posts about oreo not being stable and having battery issues and Pie having perfomance issues.
I want to know how good the lastest Pie version is, Is it stable enough and how does it compete against the old Nougat versions.
The main things i'm interested in is
- Battery Life ofcourse (I Commute a lot, thats why its of utmost importance to me)
- Perfomance (A Friend's OP6 has been observing some lags since updating to Pie, I Dont want that to happen)
Havent rooted, Not planning to do so. Had fun doing that with my Xiaomi devices, Just want to stay on the official Kernel, Roms for now.

i was in same ship as yours, i also didnt update my system from 4.5.14 to any newer version major reason being bugs as generally i have seen company give their 100% to roms when its newer ( in my case before 5T is launched ) after that it just case of mouse and cat. Sometime it works sometimes dosent and you had to wait for next update to get rid of certain issue but the new update brings some exceptional issues with them as well.
But had a conversation with someone from this forum and finally though of upgrading. First reaction was Awesome. I dont know what exacatly has changed in UI but it looks quite polished, more than OP6 that my friend has. Maybe due to the fact that i am on OP5 so no gesture control and hence no lag due to that. Its more refined and everything works fine for me. Battery life is also pretty good considering its an 2 years old device and i am a pretty heavy user myself with daily screen average usage of 6 hours ( excluding music which i listen screen off but it also take battery quite much with some high def music. So your choise now. But one thing to note is that i have heard going back is pretty hard and not as simple as downloading the rom and booting to the bootloader and flash it ( which i did quite time in nougat but that was between nougat versions as i never went to oreo ).
