[ROM] Pipo Max S2 Stock English Firmware tweaked by mrsaccess - Miscellaneous Android Development

I got my S2 on Tuesday and thought that the default firmware had a few shortcomings. Hence I took the stock English firmware and tweaked it to my needs.
Maybe you will find my ROM useful too.
So, what I changed:
Enlarged the data partition to 2.5GiB. I did this for two reasons. Obviously one is so we can get more space for apps. The other is that inside the /data partition are not only stored apk files, but the application's data files (which get written and read frequently). When a partition on a flash disk gets full, it also gets slow. So hopefully with 2.5GiB you will always have enough free space to keep performance up.
Rooted and the new, open source Superuser included.
Replaced the default launcher with the latest Nova Launcher.
Included Titanium Backup.
Changed the read ahead of the flash memroy to 1024KiB from the default 128KiB. While there isn't an overall best setting, I feel that this helps a lot with Chrome, which had huge delays while trying to load a page from its cache.
Changed the default io_scheduler to deadline. it gives better responsiness.
Default notification ringtone changed to something that won't cause heart attacks.
I added proper OTG support. Our tablet supported usb devices only on the OS level and not on the Android apps' level. So while a hardware keyboard would work, camera tethering with DSLR Controller wouldn't. Maybe Pipo did that because the tablet's usb system isn't solid. USB OTG doesn't work always, but at least it always works after a reboot for me and it is awesome to control my DSLR from the tablet.
Added support for cifs (smb).
Removed some apps and widgets which I think aren't that useful.
You can flash it with RKBatchTool. The first boot will take a bit more time until it gets to the launcher screen.
There may be some S2 tablets with a newer front camera module. If that's your case, your front camera may not work.

if you know a better host, please suggest
Disclaimer: If you break it, you keep it. I won't take responsibility for broken tablets.

I got CWM on my Pipo s2. I can install the ROM through there, yes?
Also, think we can see CM 10 on it anytime soon?

This ROM can only be flashed with the official tools, it doesn't support CWM, nor it installs it. If you flash it, you will lose CWM.
As for CM, I don't think we will ever see it. Chinese vendors do not give much information or any source code, so it is practially impossible to do a port.
Some guy started working on a CM port for RK3066 devices, but as far as I know he hadn't much success other than a very alpha rom for his device (not the S2).

Ah I see. Well thank you very much for providing this ROM! Is there any way you can provide a short step by step tutorial? I've downloaded the rkbatchtool but alittle unsure of how to proceed.

Great ROM .....Many Thanks For This Great ROM .... Now Downloading .. Please Check My PM And Please Reply ......

hi mrsaccess, still possible to get new links for the custom S2 rom ? thx in advance.

[ROM] [3.2] Vegacomb 3.2 Build 9n and 9b Update3

Ok,
here is our new release.
Well... Here we are at last! Whole new ROM, whole new thread
For a long time we have been working to build the best possible version of HoneyComb to the Advent Vega. It has been a LONG road, with many hacks and pitfalls along the way. We started with the messiest set of files anyone has ever seen, and we have now progressed to this. Full-fledged, GPU accelerated, NATIVE, Honeycomb 3.2 on the Advent Vega.
There's no going back now. I'm so happy with this ROM that I'm actually going a little crazy with affection. There are still some bugs... Rebooting to CWM causes a stale boot, you have to hold power to turn the tab off, then on next bot you get CWM. Still no camera, bluetooth isn't working. But other than that... Well, I'll let you guys see for yourself.
On the speaker issue, I feel I must put a quick note here... We BELIEVE that the "Overheating speaker" issue is now resolved. Audio levels are now well within the safe limits, and voltages are back at what should be a very safe level. But as always, please be VERY careful, unfortunately we cannot be responsible for any hardware failures resulting from using a custom ROM, but we are very confident that this issue should now be totally resolved.
VegaComb 3.2 Build 9b und 9n Update3 Features:
Update1+2 included
The clock and date issue should now been fixed for all
GPU RAM reduced to 96MB , more RAM for Apps
support for high Wifi channels like 12 + 13
new Honeycomb market
support for the soon coming GPS App included
Downloads, please choose the right Version (original ROM download is at the bottom of this thread!)! (or you Bootloop) :
Update 3 for Build9n: VegaComb_HC3.2_Build9n_update3.zip
Update 3 for Build9b: VegaComb_HC3.2_Build9b_update3.zip
VegaComb 3.2 Build 9b und 9n Update2 Features:
Fix for Bluetooth MAC addressing to hopefully make BT work correctly now.
Above fix should now also make WiFi considerably more stable.
Fix for people who were experiencing issues with the Market not being able to install apps.
Downloads, please choose the right Version (original ROM download is at the bottom of this thread!)! (or you Bootloop) Update 2 can be installed directly over 9n OR 9n-Update1 (it includes all of the Update 1 and Update 2 changes in a single package):
Update 2 for Build9n: VegaComb_HC3.2_Build9n_update2.zip
Update 2 for Build9b: VegaComb_HC3.2_Build9b_update2.zip
VegaComb 3.2 Build 9b und 9n Update1 Features:
Working Deep Standby
Updated camera lib
Re-added App Drivemount
VegaComb 3.2 Build 9b Features:
•Coarse location discovery (based on WiFi connection) is now working correctly.
•Updated camera libraries to the latest version thanks to the development effort by many (including Eduardo and Redscorpion) over at MoDaCo. Google Talk video chat should now be working, as well as the stock Camera app. Other apps have been tested but there is a possibility that not all of them work (please test and let us know!), but we felt that it was more important for Gtalk to work as the camera isn't much use for actually taking pictures
•Added Eduardo's accelerometer patch. This should allow much more responsive accelerometer with no lag.
•Power management for bluetooth/wireless has been fixed. Hopefully this should stop them interfering with eachother when one is disabled.
•Screen calibration functionality built in to the kernel to calibrate on the fly.
•USB on-the-fly host/slave switcher integrated in to the kernel, this should allow switching between USB host/slave on the tablets side USB port without the need to reboot!
•Disabled device suspend when the tablet is connected to an active USB connection, preventing the USB connection from being severed.
•Added a brand new app called: Shuttle Tools which includes the toggles for the above two options. Allowing you to calibrate the screen or switch USB modes from within Android.
• Better language support then 9n, newer Gapps
• No apps are moved to data
• It have a bigger system partition then 9n, so when you have bad nand blocks, this could be work better for you
• When you use the Full Rom Installer you don´t need to flash ModdedstockV2 (Beware when you flash the new full rom it is like the ModdedStockV2 install, you loose all data)
• All future updates after this Full ROM will come as CWM update zip, so that your data are save
VegaComb 3.2 Build 9n Features:
Please be aware that although there was a "version 9" release on some German forums, this update was never integrated into the full build process, and was a side-project by rebel1 to acheive 2 goals. 1) To greatly increase the /system partition size (from 150mb to 200mb) and use that size to add larger apps that have increased language support for non-english speaking users. This build is unrelated to the previous "build 9" and as such has been labelled 9n (new, or newbe5, meaning that it has gone through the usual build and testing processes by myself), an alternate installer based on THIS build will also be provided by rebel1, including the expanded /system partition and enhanced language capability, this alternate build will be labelled 9b (bigger system, alternate build) and will be an nvflash installer rather than a CWM image.
•System image has been shrunk considerably, this should help people who have a lot of random lockups / install issues due to bad NAND blocks. Build 8.1 was using 149.5mb of the allocated 150mb provided by ModdedStockv2, Build 9n is only using 139.8mb allowing much more room to avoid bad blocks if you have them.
•Google Books has been removed entirely. It looks nice, but it's pointless as you can't even access the Store outside of the US. Install this manually if you want it for some reason.
•Google Maps and Street View have been moved in to /data to save space and because they can both be installed/updated from the market, so there is no need for them to be in /system.
•Coarse location discovery (based on WiFi connection) is now working correctly.
•Updated camera libraries to the latest version thanks to the development effort by many (including Eduardo and Redscorpion) over at MoDaCo. Google Talk video chat should now be working, as well as the stock Camera app. Other apps have been tested but there is a possibility that not all of them work (please test and let us know!), but we felt that it was more important for Gtalk to work as the camera isn't much use for actually taking pictures

•Power management for bluetooth/wireless has been fixed. Hopefully this should stop them interfering with eachother when one is disabled.
•Screen calibration functionality built in to the kernel to calibrate on the fly.

•Disabled device suspend when the tablet is connected to an active USB connection, preventing the USB connection from being severed.
•Added a brand new app called: Shuttle Tools which includes the toggles for the above two options. Allowing you to calibrate the screen or switch USB modes from within Android.
Current issues:
On rebooting to recovery, the tablet will "hang" on a stale boot. Hold down the power button until the screen goes completely off, and then power back on to get to CWM.
More? Probably! You tell us

Oh... I might have done some stuff too
Remember, this MUST be flashed over ModdedStock v2 or it will not work!
This is the one and only way to move to our image:
modstock -> data wipe -> vegacomb 3.2.
Dont ask for help if you dont follow this steps.
Download VegaComb_HC3.2_Build9n.zip NOW! This is for all users that comes from an previous build like 8.1 or ModdeStockV2
For users that comes from my Build9 they can download and flash it with CWM recovery Download VegaComb_HC3.2_Build9b.zip HERE!
And the last file:
Download VegaComb HC3.2 9b Installer.zip HERE!
This is a windows installer for the 9b Full ROM, you don´t need to install ModdedStock before, it makes it all for you
We hope you enjoy VegaComb.

Great job guys!
I can hardly wait to test this one out!
Very very speed rom..
Thanks
This week, I'm going to receive my Advent Vega. I believe this is the best Honeycomb ROM available (better than Vegacomb 1.7), is it correct?
Thanks!!
wow, loving this as it really does fly, very impressed.
I've just installed it. It really does fly. Just installing my apps now. Will let you know if I come across any problems.
Sent from my GT-I9100 using XDA App
SHWIINNGGGG!!!
Thank you gtablet gods!!!!
I must say i just installed it and its fast!!!
Faster then my gtablet on gtabletcomb 3.3.
OK so you vega gurus. whats the difference between advent vega/viewsonic viewpad 10s and the gtablet.
why can the roms be ingterchanable and whats the difference.
thanks for the roms guys, Now I dont have a reason to sell it.
youtube restarts itself when you rotate the screen.
Apps from market forcloses...
was using opera for a bit with some flash content, went to the home screen and went back to opera and the tablet resetted itself.
what do you mean by "Native App2SD has been added back in (is not present on 3.2 ROMS as standard)."
Does that mean we dont have to get the app2sd app?
I looked for the app2sd in the settings and is unable to find it.
can you please explain..??
I love it, thanks for your hard work.
awesome build
much much better than beta 1.7
thank you so much for that.
just one question, compare to 1.7, all icons look too big.
different resolution or different density?
I don't think we can change the resolution.
Thanks.
Edit: I use LCD density to make the icons smaller, got wifi error, after uninstall lcd density and reboot, no error.
aarrggg... I'm at work and can't get this till I get home.
5pm can't come quick enough now
Been playing with this since yesterday evening.
You can change the screen Res in your build.prop file. I'm on 140dpi at the moment, many people seem happy with 127
USB host mode doesn't work yet, hopefully not too far away
Everything is really fast. No lag at all. There are a few little oddities here and there but nothing too drastic. An amazing release really.
HDMI out is working? My TV didn't recognize it. Pretty fast. I set the density to 140. Looks better now. Thanks.

You need to hold power button until you see the power down menu, select recovery then it'll hang on reboot, hold the power then until the tablet is forced off and when you power back up, it'll boot into cwm recovery
could someone with an official dock please try and see if they can still connect usb peripherals on this rom, I know you can't directly until they fix it, but was wondering if it still worked via the dock. If so i'll buy one
thanks,

Hi there.
I have been running this for a few hours, i have got to say, its fantastic. So quick and smooth. I think i will be running vegacomb from now on.
Just curious about the keyboard, it seems very small. Is that the stock one for 3.2? No major problem just installed hackers keyboard.
Still not sure about the pixel density, but i can easy change that.
Love the first boot screen, should make it more difficult to bang out a vegacomb clone on ebay
Any tips on getting the accelerometer working properly with games?
Many thanks to you and TeamNewCo, this is a fantastic ROM
Legendary. This rom is awesome.

[Q] Simple Google ROM for GT3110

hello,
It may have been already posted, but i would like to put on my GT3110 a simple & stable ROM without any additional SAMSUNG layer or any other modification.
i've tested the ROM provided by default, very slow and too much stuff that i don't want in it.
i've then tested the CyanogenMod 10 nighlty build, but the Keyboard wasn't working even after having done the clean as recommended on the web.
i've then tested the ROM RomsWell but it contains the SAMSUNG layer.
i'm now using the Paranoid Android 2.51 but the paranoidSettings seems to modify the resolution of the tablet and icons are not positionned correctly when moving from landscape to portrait.
i don't forget how big the work done by all these people providing this for free mainly, but as this tablet is dedicated for a gift to someone not android addict nor interesting in changing ROMs regularly,
So i would like to implement a Google stock ROM with nothing more/less than what is provided by google. even if i loose some performances or other things.
can you tell me where i can find this for the GT3110?
thank you in advance
If you install a launcher like Nova Launcher Prime, you'll find much of the Samsung layer gone. Some of the Samsung apps are superior. Email, Contacts and Planner come to mind. I would call the system easy for unsophisticated users and reliable as well. There plenty of help and a real user manual.
I've been flashing roms for years now and decided to stay with a rooted SGT27. Custom roms, even AOSP aren't that easy to use and there are always bugs.
This .....

If you (or the person its for ) isnt into modding Android, stick to stock. I use Apex launcher (Free) and to be honest they are all pretty much the same. Touchwiz isnt that bad and Samsung stock apps are really cool.
I would suggest updating it to JellyBean stock via Odin/Heimdall or just wait for the official update via Samsung.I personally use AOKP M1 but its a little confusing to set things up at first and needs tweaking.NOT noob friendly at all and takes time to work it out. ( but that's why I like it).
I would be careful giving "Root" access to inexperienced users as they may get themselves into trouble with it....Remember it gives them full access and control of the ROM. I would suggest a start up manager either way ,to stop all the junk starting up when you boot. Samsung loves bloat lol.
If you want pure Android, flash an AOSP no frills ROM.

This does not exist, in fact it does not exist for any device. Stop dreaming of the mythical "clean" ROM that is 10x faster. There is a lot more to a functioning ROM than Google open source Android. There is no such thing as a pure AOSP ROM for any device because its takes Android + kernel + drivers + libs + apps + bootloader + etc. to have a functioning ROM. and everything except the base Android API is device and version specific.
The Samsung touchwiz launcher doesn't slow anything down and if you don't like the way it looks, as suggested above, install one of the good third party launchers and its not even used.
I find this tablet running the Samsung stock ICS to be very fast and clean, So one would wonder what are you doing to it to make it "slow" There's only a few Samsung apps included and unless you run them, they just sit there doing nothing. You can hide them if you don't want to see the icons.
thank you guys,
i'll try the JellyBean standard ROM as recommended and try another free launcher

Got ideas how to achieve root? KitKat method or any specified methods?
Amazing work, Daniel. Thanks so much for your effort.
My impressions on this release: battery life is AMAZING, a lot better than official firmware; I am unable to play any kind of video, Youtube included, that´s the only thing that is really bothering me since I use chromecast to watch movies from it; Incredibly fast and responsive; some screen tearing when browsing the web (using Chrome); I don´t know if it is just my imagination but the color scheme seems to be a little "off", contrast is a bit down; some reboots here and there, it doesn´t seem to have a specific reason.
Well, that´s it. Thanks again for all your work!
cm 12
Its super awesome we are seeing lollipop on gt6810 all though there were some fixes need for video decoding and others. I did try it out but all the roms I've tried don't quiet give me the simple stable experience paranoid 3.68 gives me especially with camera flash everytime its opened for new pictures to be taken and browser distortions which is hardly experienced in pa3.68. Looking at the paranoid rom, do you think lollipop could use abit of the old experince of paranoid just incase the new updates coming out of lollipop pose abit too much of difficulty?... I really would love to see this awesome lollipop interface you've given us a chance to experience on a paranoid kind of feel...u know... Also, compared to how light paranoid is, the kitkat and others seem to perform under alot of pressure. My tab practically gets really warm when watching a video on low screen light and a minimized volume. These things are scaring the crap out of me so I've reverted back to paranoid. Would love to have a positive feedback, hopefully... Once again, Thank you for the work you've done so far.. You're aweSome!
---------- Post added at 05:38 PM ---------- Previous post was at 05:32 PM ----------
My laptop got stolen recently.. Really wanted to tinker with this new build. now I have to do that directly from my tab somehow...really depressing and stressful but all goes well, hoping for a better future with cm 12.. :cyclops:
I Need Multi-User Support
Thank you Daniel. I love it!
I hope that the multi-user support will be added in the next build. Your efforts are greatly appreciated.
Happy New Year!
test results for 5/1
very usable but not too stable,random crashes,auto restart,freezing
apps start fast but then lag a little
over all almost can be used as daily drive other than lag and random random crash and reboot
miss xposed and themes engine,lollipop has an annoying green-white theme ,yuck
Some issues with 10th Jan build
Hey Daniel,
Firstly, thanks a ton for your hard work. I check this forum on daily basis to check out new builds if any. I really love your work. I am still using my 3 year old tab just because of you.
I have installed the the 10th Jan build. There is one major issue I want to report. When I leave the tablet on for sometime untouched on charging or anything. I come back and try to use it at the moment the screen never switches on. I have to push the power button and hard restart the device again.
It seems to be dying out after going into deep sleep and need to be restarted to start using again.
If I am missing some solution for this please let me know so i can fix this. Otherwise this new build and new kernel is awesome. Even the speed of device has tremendously improved.

reboot into recovery
hi
I installed this cyanogen rom on my P6800 , but in "Rom Manager" app i couldn't Reboot to Recovery.
when i press "Reboot to Recovery" my tab doesn't reboot!!!!!!!
Great Rom
This ROM is by far better than kitkat on many ways...and its much more stable... So far everything works perfectly...the only small thing is, I think lollipop is abit too heavy on the tab 7.7. Cm 12, I'm really enjoying the feel... Thanks Dan.
So how can lollipop feel lighter but with the same features? In terms of its memory management, speed at which it can process one or more things at a time and considering where tab 7.7 is coming from, it doesn't seem all that simple...
Also, you we could tell you if there were any problems.. No distortion or anything but there are minor flickers which kinda scares me..I hope its nothing. The flashlight function don't work. Any gapps higher than the micro version, I get this error "insufficient internal storage-aborting installation'. I use the latest TWRP.
Is it possible to get a camera app with photosphere? I really love that function in a camera..
Everything else works just fine...WiFi works better on da kk versions and much better on da lollipop (cm12). Like I said from the beginning, seems the lollipop weighs the tabs overall performance down a lot.. I couldn't find anything in the root folder that helped so maybe you could teach me a thing or two about that area on android lollipop...
I have a tab gtp6810
Thanks
And o, the previous ROMs that some people complained about the charging running down the battery instead while plugged in and running at least one app like the browser... I did a power supply reset in the terminal... I don't know if worked but I'll give a feedback here if I see any improvements for everyone using any of Dan HK ROMs...
fifth try
Well, I only installed the cm12 without gapp.. I'm going to fix in the apps I want from the gapp... So far, running abit smoother than with gapp install along cm12 together... For the torch, I'm going to take the one from cm11 and try make it a system app.. Also, the camera...the flash only works when every time you open anew and take the first picture or select through the flash settings.. Just like all the previous ROMs from carbon to slimkat... Only PAC and paranoid 4.2.2 are the last that works the way you would want..but graphical interface ain't as good as this..hehe
---------- Post added at 09:10 PM ---------- Previous post was at 08:57 PM ----------
The dalvik heap size allocations...do they work through the system's available storage, ram or some separate caches space separated? I sort of change those area abut..there was abit of change around the graphic performance and processor...couldn't really tell but it felt abit different... Will those sort of changes affect anything negatively as well somewhere in the custom firmware? I want to be careful I'm not doing anything wrong...
runs good
I think it run better without gapp....only difference is, you won't have all the Google service interface eating away your battery and stuffs power related.. Also, recent app button, the apps take abit more time for the close sign to appear... Its basic issues still remain like the missing torch function But in all, it works very good.. U think this new cm 12 could actually become an OS on it own? I've been going round the web seeing as how Aroma installer are popularly used with different cool installer interfaces... Cm12 so far ROCKS!
For those having battery charging problems, get the stock recovery (it worked for me) and flash in the pit file for ur device as well, seems to help somehow...you can try sbl bin but I mean, its just an idea... I lost my laptop so I can't manage going back and forth from friends houses all the time...
few cm12
Bluetooth..pair and connects with some av control. Didn't realize the tab was my PC now. Sending files..-"no bluetooth device found" (while paired or with the extra a/v connection).
Tab turned off, trying to charge under twrp 2.8.2.1, "battery draw jpg cannot load" or sth like that. Not sure what that means but a white one shows charging after the error.
Mobile Odin can't see nor access external SD.
On first install, Google search appears after turning off in launcher settings, open recent apps tab (show up here insteadv big and white), go back and turn on in setting,"heeeyyy, you're here!! Welcome back to my screen..lol".. So its not ICS version I see on the home screen.
Live paper on, turned on Bluetooth first time and device restarts. Surfing over 5 tabs on browser at the same time, restarts. Also, using an app like torrent to download one file while watching a movie (tab get very warm & freezes completely and unresponsive till I keep on power button till it restarts the device)
But I'm only testing all this with a fresh installation and gapp 5 beta 12 nano. I haven't changed any settings at all. Just want to help out with more feedbacks on overall performance.
Most responses to apps opening and closing can be slow in moments where about at least three or four apps have been opened.. So I have to manage an app at a time while clearing my recent apps. And surface a page or two unless with a different browser like UC browser, its okay.
Colors, everything feels cool. Flashed lollipop font and system sounds (don't remember where I got them but I'm sure it was on xda). It sort of felt like I was using the kitkat version that's why I changed them. Runs and feels abit better than my first time install cm12.
I don't know if there are any memory forced to leak but maybe you could hover around to see if something's is abit off about it from what I've said so far.
So between recovery and custom ROM, seems there's some unstable thing going on from within their interactions... I don't know, maybe recovery also needs an update....I guess...?... Well, you're the expert so these are my user experiences so far... Will let you know if anything else comes up
This new lollipop really is different. I can't even tell in the lib files are supposed to be in the apps or lib folder or both when trying out an app like the latest Google camera. I've tried but I only get as far as paranoma and it stops working at photosphere. Sometimes it opens but da circle has no use when the pictures are supposed to be taken. Read from file to file, I must say...I have never been this lost in android...hahahahaha
updating on cm12 issues that could help, hopefully
Lollipop looks light but feels heavy on performance i think cos of how much memory it over-uses.. Maybe its the kernels or sth so I'll wait for what Daniel will help us with to understand more (thank you again Daniel. U're awesome!)
What I noticed today was, when the memories goes to its limits in usage is some areas I think, the tab glitches, slows down abit and restarts if anything else opens... I was only watching a movie series (homeland TV series) from my 32GB SD card, and downloading a ROM from media fire with all my apps closed but the system running. No other recent tabs were opened.. Before I continue, I limited the memory use so between 5mb to 256mb does seem enough unless u r da type that multitasks a lot more (but that should not the case, right?...weird tho). I did this cos when I increased it, with a bit extra apps (about 1 or 2 etrxa apps running), its kept either freezing badly or restarting. So I just had to test this to see if its me or this new OS is going to be hard to work with...
Secondly...I use MX player a lot... Sometimes hardware works but when switched to software decoding and back to hardware, suddenly hardware is not supported unless I close the current video or app itself and start again. But will still fail at hardware decoding and sometimes restarts unexpectedly during software decoding.. Too much info?...haha... Naaah.. Lol
JESUS! The cursor is abit difficult to move around with a huge finger that covers it completely...lol
In case you are wondering,"where did this guy come from"...I assure u, I have been a fan of xda for about a year or two maybe or more cos I remember using my first tab its been almost or over two years. I only recently joined cos android has fascinated me in many ways and by having alot of great customization options and being an open source if I may add... I'm happy old devices get to meet the challenges that people have doubts on.. I'm grateful that I still use some of my old devices with a lot of confidence...

hi
I installed this cyanogen rom on my P6800 , but in "Rom Manager" app i couldn't Reboot to Recovery.
when i press "Reboot to Recovery" my tab doesn't reboot!!!!!!!
Click to expand...
Click to collapse
Really? How did you install it? And did you do a factory reset after install ROM or clearing cache and dalvik cache? Have u tried a long press on the power button to shutdown first?
As for ROM manager, I can't say for sure I can help u with that but I also noticed some things like mobile odin don't fully run all its functions on my tab p6810 with the p6800 kernal I found for mobile Odin to work o my tab.. I can't see the external SD unless i copy da file I want to use to the internal storage... So cm12 is still a working progress I guess.. Refer to the original cm12 post...Daniel said sth about the we probably will have to end up with our own new custom kernel to use I think due some out dated resources...For now, if no options works for u... If u know how to open the tab gently to take out the battery's connection and back in to enable u go into recovery to do a back up just in case... The u can sort out the ROM properly...and only if ur tab doesn't allow u to shut it down manually... At ur own risk..u can watch YouTube videos on how to handle ur tab p6800 with care when opening..
I've used twrp recovery and cwm recovery (which cwm needs to be rooted before flashing ROM), they all worked well for me so far.. A feww issues I've already pointed out but could be sorted eventually..
I searched da web for info and made a few changes to my build prop. Would share with u if interested...but remember, I'm only using the WiFi version of ur tab..
---------- Post added at 02:20 PM ---------- Previous post was at 01:57 PM ----------
I think the last cwm recovery works abit better (if in case u have charging charging issues and don't want to use the original stock recovery).. U flash that and root ur device through the recovery, restart recovery to root or fix root then install cm12 with mini or nano gapps 5.0. Battery draw is missing in ROM but don't worry, it will still charge.
I want to share my super su which I flashed to root the device but I can't get the upload button to pop up any window to find the file on my tab in the system's browser on the cm12. Well, all the same...Good luck!
I wonder if this is what they call a memory leak...
Three words...poor memory management... For an old device, lollipop settings over use tab hardware resources..though its performance is better in terms of gaming.
OK...I said I made a few changes to my build.prop...well, here they are:
#
ro.sf.lcd_density=180
ro.HOME_APP_ADJ=1
#
wifi.supplicant_scan_interval=84
dalvik.vm.heapstartsize=7m
dalvik.vm.heapgrowthlimit=49m
dalvik.vm.heapsize=294m
dalvik.vm.heaptargetutilization=0.72
dalvik.vm.heapminfree=788k
dalvik.vm.heapmaxfree=7m
dalvik.vm.lockprof.threshold=600
These are lines I made changes to (p6810)
******
I'm using nova launcher as system launcher
Flash some L fonts and sound I found on YouTube
And boot animation
Just to try get it to feel like lollipop as much as possible..
I notice a white line that flickers between long minutes like about 45mins during a movie playing on my MX player.. It also happens during charging the device when running twrp I guess...i see that on my lockscreen when on landscape mode...don't really know what that means...but I take out the charger for some time and plug it back and it stops for a long while but I switched to cwm.. Da MX player thing still shows though..
I removed that performance tweak app... Can't risk overheating...sorryyyy...I get scared a lot when I know my device hardware has its limits and way of coding to the responsiveness to whatever android versions out there....and I guess it all depends on the hardware make or build period and its sources..
Well, catch ya'll later... Still waiting for kernel and/or some ideas...
Cm file manager don't do much aside from viewing files and folder or install apps..
I tried material manager pro...that too crashes when I try to select everything at once in a folder...have no clue what that means either but will make time for the apps later.. Right now, cm12 needs a good workout till I feel its stable enough for extra updates from Daniel and others who enjoy helping g out....
PEACE!!
tasty lollipop
arrrghhhh! Wish I had an 'F5' button on my Google keyboard!!!
Just messing around..lol... But seriously though, you use it for abit with different apps running and closed...then remove all recent tabs...restart, you have most apps you opened which a lot are related to Google running as background processes......mmmmm....didn't realize the system takes me abit too seriously...Haha
So now, I have 'ccleaner' and 'the cleaner' installed. Ccleaner runs... 561.6mb ram of 770.97mb used. Okaaaay..........analyze....clean processes, empty folders, cache....no changes to memory.....awkward...lol..
Now, 'the cleaner' app- analyze, 197mb or sth to be recovered...nice! - 'clean'.......384.84mb in use...shows in ccleaner....wow!
This is.....sth......
Ok so, system bootup........Google+ and YouTube are background processes.... Sometimes 'music' pops up....weird....I.....don't think I'm ready to dance just yet... But after a while they get tired and leave, leaving YouTube behind.......maybe it wants me to watch xda videos....... Ok, so Google app pops up when I've l've literary stopped all its functions... I haven't force closed it, no no no...well....not yet but I will....
I once saw Google service and Google play service pop up...are they related?
Also, I would like to make guess or assumption; I think it takes abit longer to load everything compared to previous ROMs... Even when its already booted to home screen..
Ok, so some was last night's observations.. I think this gapp is going to make me saaad.
Will use only cm12 without gapp and run the Google apps manually instead to avoid multiple background processes at once...gms core.....interesting and can be quiet a strain...o well.....laterrrrrrr

While awaiting Android N for our Pure (XT1575)...

I decided to try out simplifying my phone and reduce issues that I've come across when using various custom ROMs, modified stock ROMs, etc... and used the Restore-To-Stock tool found in these forums. I then updated the phone via Settings, About, System Updates... then once that was done (Several times...) I was fully updated and ready to go. I flashed the latest TWRP & then installed the latest SuperSU for MM via TWRP... went into the file system and removed the APPs I did not want or need on my phone, wiped the caches and rebooted... I did this a few days ago and am insanely impressed by it. I forgot what stable and issue-free felt like... There's no fancy custom edits, no oddball quirks randomly from whatever was modified from various ROMs and after I installed xPosed, a few basic modules, setup Nova Launcher and all my APPs (Did a full fresh no restore of anything run through of it all)... I am the happiest I've ever been with my Moto X Pure (XT1575).
Once N pops in, I'll go through the whole process again, of course... but I think I might start sticking out simplified setups from here on out. I wanted to get the next Google "Nexus" phones released this year, but after seeing the Pixels and the prices... no thank you, I'm staying with my Pure for a while. I'm VERY happy with it... Dual front facing speakers are pretty much a necessity now for me. Internal Storage and Removable Batteries (prior to my Pure) are no longer my requirement. I've adjusted to pretty much using Google Drive and Google Play Music for all of my Files & Music with T-Mobile's no-data-cost of Google Play Music Streaming, I download my favorites (All I ever need would fit on a 32GB phone easily)... and Google Photos auto-backup has prevented me needing tons of storage options anymore... Battery you say though? No... I've YET to have a phone I wasn't able to charge on-the-go or even have a battery go bad.
Rambling here, this post was probably more for me than anyone who might read it, lol... I wanted the Moto Z so bad... but if I can't get an unlocked one that has the shatterproof display to use on T-Mobile... I don't see myself getting one at all. I want my next phone to have a fancy AMOLED hopefully shatterproof display with dual-front facing or at least a mod for sound / speakers like the Z and perhaps smaller top / bottom bezels. Not sure if I care about a fingerprint sensor yet or not. Anyway, have a great day everyone!!!
Have you compared debloated stock to tru pure x?
I've been thinking about doing something similar for the last few days. I've been running the latest TruPure since it came out several months ago. It might be the longest I've ever had an Android device without doing a clean flash of something, and things are degenerating.
I've always been a huge fan of TruPureXMM but have run into a few minor quirks here and then over time and definitely feel this is proving to be a much more stable experience. I removed (debloated) pretty much everything TruPureX did when it comes to APPs, but I believe TruPureX had a lot more going on than just that, which is what prompted me to go this route.
Since we're all sort of waiting for the official N, and we all know it won't be here amazingly fast... I've opted for this route to stay with the official run of things until N is stable and available through the official channel. I'll go through the full official update process and then TWRP and Root after... I'll be able to stay away from xPosed at first simply because the only things I'm using now are making MM more like N and I won't need to do that with N. I'm hoping once I can TWRP, Root and debloat by deleting the many APPs I don't like... things will be great!

You've made me interested in trying this out as well. Is titanium backup the best way to remove system apps or is there a better alternative?

What I've always done is go into TWRP and remove them myself. Going full fresh no restore means no real need for Titanium. Return-To-Stock first, then OTA your way up to current... THEN TWRP and SuperSU... then boot in, make sure everything is working and jot down on a piece of paper or Google Keep from your computer a list of the APPs you don't want.
Then power off, get into TWRP and mount /System, go into Advanced, File Manager and within /system/APPs and /system/PrivAPPs (Or something like that, memory just blanked) and find what was on your personal list... enter the folder for it, hit button bottom right, choose delete, done, go back and do the others... then wipe Cache / Dalvik and power off / boot up for the absolute freshest experience you can have with a stock ROM.
The trick is to NOT restore ANYTHING... install all your preferred Google APPs first, do the whole Google Phone install if you removed the stock Phone app, etc... (I remove it and the messenger, and a bunch of other stuff like the gallery, mail, etc... because I solely use Google services now).
I removed my case cover and have been carrying the phone around bare.
It's like I bought a whole new phone.
Have you guys tried a quality AOSP based ROM like Dirty Unicorn or BrokenOS?
Super stability. Nothing at all like running a CM ROM.
Testing cm14 now. Hashbang is doing a great job getting it daily worthy.

10/11 build will I bet. :highfive:
What apps/services did you remove? I'm running stock rooted myself and honestly I only see a couple of things I'd get rid of, nothing that would have any real impact on battery/storage though. This phone's stock ROM really is close to AOSP.
same too what apps did you remove tnx.. im not rooted .. tried uninstalling apps and guess what it got temp bootloop.. did hard reset using stock recovery and got fix again started tru welcome menu.... may i know guys what apps not to unistall tnx
Did a side by side comparison of apps in TruePure and stock. I counted 39 apps deleted from TruePure.

It seems that contributing to LOS building ROM is not anymore tolerated, this post is deleted.
Maybe @Scavenger87 wants to take a look here ;-)
I guess it's better to have an own dedicated thread.
Thanks for setting up a distinct thread. Things were getting confusing!

Hey John great idea with opening a new Thread because i also think its really confusing already
john_matrix said:
@Scavenger87: Steel01 advised to let 15.1 (I think he is right because it's too old and because lot of changes have been done between 15.1-16.0)
Also have found this during LOS 16.0 debugging and when application is crashing:
Starting from Android 9, LMK can be implemented in userspace and needs new optimization settings:
Low Memory Killer Daemon | Android Open Source Project
source.android.com
Will see if this new userspace LMKD can be tuned.
@Trevor_g: can't say... I don't have an Nvidia controller to test.
Click to expand...
Click to collapse
Ok yeah i think he's right for multiple reasons
- 15.1 had still unsolved issues aside of broken omx like the crashing nv games app and not working screen mirroring which is working so far on 16.0
- 16.0 is Android 9.0 based which is the same as the actual Software for the Shield TV. That means there is maybe a chance they can use some Codes or even Apps like the Shield Accessories to makes things like the First Controller working again over WIFI.
I even found a lot Nvidia OEM Apps here on APK Mirror : https://www.apkmirror.com/apk/nvidia/
I think i start testing around with those apks as soon i installed the lasted 16.0 build
@Trevor_g
For your question i have to check that again on 16.0 with the old Controller but i think its still only working over a OTG Adapter.
Like i mentioned above maybe the Shield TV Accessories App is working.

Someone even mentioned this Linux Driver for the Controller
But to be honest dont suspect too much on lets say all this bonus functions because first the LOS Team have to work on the base build to make it stable and running right
Ok i installed the latest build (4/1/21) yesterday on my LTE Tablet over sideload because i had no extra SD Card to format it to FAT32 and with the new TWRP 3.5-9.0.
I installed also the Pico Gapps and then TWRP said when i was about to Restart that there's now OS installed.
But thats seems to be a bug with TWRP itself because after the restart there was the LineageOS screen waiting for me and after a freeze for about a minute or two i was able to complete my installation.
After this i now can say its the most stable LOS 9.0 Rom so far !
It has very less apps crashing so far i only had to start them twice sometimes and also the hw acceleration working now most of its time at Chrome and on the Youtube App.
I can really see there has going again a lot of work into this Rom and its really a pleasure now to see how it get more stable everytime.
Big thanks to @Steel01, @npjohnson, the whole LineageOS Team and of course to @john_matrix
Btw @john_matrix did you change anything on the partitions you mentioned earlier on this build ?
@Trevor_g
I did a short test yesterday with the controller and as suspected it doesnt recognize by the tablet. I soon test out those Android 9.0 based Accessories App from the Shield TV
Thank you for the rom
Can I just flash this over Lineage 14.1 or do I need a factory wipe?
Did anybody test gamepass streaming yet?

Yes you have to wipe the device first in TWRP to install this rom.
Maybe a little general guide for everyone here who want to try this build in this early state and help tracking bugs
For an clean Installation its important to wipe the device first with TWRP like shown on the first Screenshot.
After this go to Advanced and choose everything choosen on the second Screenshot.
Now you shutdown the Tablet and insert the SD Card or plug in the cable for sideloading.
After turning on the Tablet and choose Recovery Mode again, first install the Rom of course then choose Wipe cache/dalvik.
Now you have to install Gapps if you want to use it. Its recommend to use only the Pico Package.
Wipe cache/dalvik again and restart the device.
If you use Sideload it might says in the Shutdown Menu :
No OS installed !
Which is a bug in my opinion of the new TWRP 3.5-9.0 Package but please use this Version of TWRP in any case that the basement of the installation is everywhere the same !
This is IMHO the way to install a Rom in a clean way and helps tracking down bugs better when everyone used the same methodes.
@john_matrix
I installed the Rom today on a K1 16GB with the methode i described above and did it with my regular SDCard i use in all my Tablets. In comparsion to installing over sideload it didnt get the No OS installed! message at TWRP and i didnt had that 1 minute freeze at begin of the install-wizzard after the LOS Logo.
Also the Rom seems to be same stable as the one on the 32GB model.
But i have to test it a bit more side by side to make valid statements
Also Nvidia Games working nice as you can see on the Screenshots
Hi guys, so, long story short i got scammed on a dutch advertising portal and ended up with one of them shield tablets which were recalled a few years ago. Yep, those with the defective battery that may burst in flame one day
Anyways, i figured that since it hasnt happened until now, i might just be lucky and give it a shot.
Its great to see that there is still some active development of this device! flashed this rom and i gotta say im positively surprised. Its running nice and smooth and even though it crashed on me a few times after the first boot, but a few reboots later and its running like a charm! i didnt bother with gapps, root or anything yet though. really great job devs!

My tablet was completely wiped with no OS so I just pushed the ROM, pico gapps, and magisk over USB onto internal storage with MTP/TWRP. Flashed it all from there and it worked fine. No issues or errors. I don't think it's at all necessary to sideload to use an external SD.

In this Thread beginning from here i share my informations so far about the two type of batteries and changing them out if you interested:
Finding Replacement Battery in 2017?
Anybody know where to find a battery that will fit in the Shield Tablet? I know there are several threads online (here on xda, on GeForce forums, and other places) that discuss replacing the shield tablet battery and a few different part numbers...

I did these two type installation because @john_matrix mentioned to use a SD Card which is formated with FAT32 instead of exFAT. I didnt had one lying around so i used sideload this time.
Thank you everyone and Scavenger87 for your feedback! ;-)
About stability, I guess the culprit is the fact I have played with the new userspace LMK but for me it's not stable enough to be used as daily.
For example, Youtube often continue to play videos greeny and blocky and this is annoying
I will try to fine tune the best settings for LMK.
About battery, I have changed mine too with this one:
https://fr.aliexpress.com/item/32807531204.html
It works good but require to use the board of the original battery.
Seems to be going well so far for me, battery life seems good and for the general use I have had time to do it's worked well.
One crash that caused a reboot, after testing the hdmi output the tablet rebooted when I unplugged the hdmi cable from the tablet.

Ok that means there is still some kind of memory leak problem with our tablets or is the memory managment on android 9 and higher not really suited for our low ram devices ?
I also read something about drawbacks with the in-kernel LMK as you can see here :
Drawbacks of in-kernel LMK driver
Android deprecates the LMK driver due to a number of issues, including:
Low-RAM devices had to be tuned aggressively, and even then would perform poorly on workloads with large file-backed active pagecache. The poor performance resulted in thrashing and no kills.
The LMK kernel driver relied on free-memory limits, with no scaling based on the memory pressure.
Because of the rigidity of the design, partners often customized the driver so that it would work on their devices.
The LMK driver hooked into the slab shrinker API, which wasn't designed for heavy operations such as searching for targets and killing them, which slowed down the vmscan process.
Is the zRam function now activated by standart on Android 9 and higher to compress amount memory is needed ?
I try to stresstest it today with a website that have a lot pictures sadly i cant use instagram anymore because you need a account now
Shield Tablet can't be considered as a "low ram device" as Google defined them with up to 512MB (Android Go?)
Android Performance Optimization | Android Open Source Project
source.android.com
I also have devices with 2GB that are currently performing Lineage 17.1 very well (Sony Z3C and Nexus 4)
I don't know if zRAM is activated by default in Android but you still have the choice to activate it or no (in the kernel or in the fstab.
Additionnally, I don't know what is the policy to activate zRAM (my Mi9 have 6GB RAM and have zRAM activated by Xiaomi so...)
Another thing about zRAM is there are lot and lot of options you can activate such as compression, lz4, clear caching, etc... depending of your needs and I am not skilled enough to say exactly what will be the consequences of these options (but it cost nothing to try).
You also have to keep in mind that zRAM will consume more CPU times (as KSM).
Similarly, you can fine tune the CPU governor and IO scheduling (often I see CFQ by default but on the other way I have saw that Noop and Deadline gives best results).
Feel free to share your experience and if you have other ideas on what you would like to integrate in this ROM (as the best possible).
You are right to stress test the OS, you can also debug the memory and the weight attributed on the processes.
Ok but 2GB is really not much these day also this article from android source is really old i think i read there something about kitkat or so
But your right i also was suprised to see that my xperia z3 compact i have lying around is able to run lineageos 17.1 and even is supported by the LOS Team
Which leads me to the question is the memory managment on the Qualcomm SOC so much better ? Ok the Ram there is on the SOC itself instead of external like on our Tegra based devices.
I think i install tonight Triodexes 15.1 with zram to compare the effect it has.
I also noticed the hw acceleration crashes the most on the firefox browser like i told in the 15.1 Thread you can start one video and it runs if you leave everything untouched but your not able to start a second one even with autoplay.
Btw about the LMK i know its maybe a dumb question but did you try the original settings from the Oem Rom ?
Edit : The original values in minfree are: 18432,23040,27648,32256,36864,46080
And zRam is already activated on the LOS 16.0 Build with 511MB same like the oem rom

Thanks SO much for looking into this for me! You mentioned later that the controller wasn't recognized by the tablet, however I'm also curious if the Accessories app from the ShieldTV might help. Thanks again, in advance!
Fwiw, there's a bunch of framework patches needed for the wifi direct controller to work. I've yet to get them all straight. Haven't had that working since cm-12.1. See the incomplete set for 16.0 here:
https://review.lineageos.org/q/topic:shield-blake-p
That's on top of:
https://review.lineageos.org/q/topic:nvidia-shieldtech-p
And there's no nvidia pairing app that works with a touch interface. It's a mess atm. I did get blake to pair to foster on 15.1, but only while the pairing wizard was open. As soon as I hit back to close it, the autonomous group goes down and the connection is lost. And now, it's close to impossible since nvidia didn't release the nvwifi prebuilt jar to link against. And the one from O doesn't work on P.
Hi @Steel01
Thank you for keeping us updated on your work with the controller and also for your work for this device in general
I already tought its not easy to bring wifi support back for the old controller but i think also there is no high priority since the second gen is working fine over bluetooth and they already cheap to buy used.
Other than this the rom is suprisingly good running for this early stage and most of the stuff is working
Is there something that needs special attention for testing at the moment to help you developing ?
Like i mentioned in a other Thread i have every generation of the Shield Tablet and Controller. Only on my LTE Modell the SIM Card Reader is unfixable broken
But i still hunting for a fully working device.

Well i dont know if its really needed to wipe the internal storage but i think by the reason we testing here a new Rom in a really early stage we should give it the cleanest basement as possible to exclude problems that might caused by left over data that interference with the Rom
