[ROM] Pipo Max S2 Stock English Firmware tweaked by mrsaccess

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.

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.

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.

Best stock Oreo ROM to downgrade to? Giving up on Pie for now.

I'm ready to give up on Pie for now, but not ready to unlock the boot loader and go for custom ROMs. So, I think the last stock Oreo release was 47.1.A.16.20? So I think I want to find G8142_1308-6041_47.1.A.16.20-R4B_Customized_US.ftf and flash that with newflasher but I can't find that FRF anywhere. Any hints or suggestions? Maybe just bite the bullet and backup the DRM, unlock, and flash a custom ROM instead?
Problems in Pie on my G8142:
1. Many apps stop updating the screen if you have the screen lock set to None and turn the screen off/on a few times. Fixes for a while if you switch to another program and back. Doesn't happen if you have a screen lock enabled (even Swipe to unlock) but I don't like that. Seen it happen in Bumble, Tinder, OS Settings, Chrome (except there the web page goes black instead of maintaining the previous screen), Piktures (black screen instead of maintaining the image, like Chrome), Timely (where the countdown timer is still running, just the screen isn\'t updating to show that), Play Store, and Acrobat Reader. Even got it to happen IN THE INITIAL PHONE SETUP APP before connecting to my Google account when I reset to see if that helped.
2. Some apps don't work correctly on wireless data (TextNow and 2nd Line VOIP apps won't dial out or take inbound calls if not on WiFi on Pie, Waze loses connection every time you move from WiFi to wireless so you have to exit and re-open once you are out of WiFi range - though I'm not sure if this is exclusive to Pie or not, Grindr can't send or receive chats outside of WiFi - just shows Disconnected.)
3. Pie disabled call recording apps.

I don't have any of these problems and I'm on pie. I guess if u wanna stay on stock oreo u can. But pie doesn't even require drm keys anymore. I'm on lineage stock of pie and haven't wanted to go back to oreo since

Interesting! What do you mean by "pie doesn't even require drm keys anymore"? You mean a custom ROM with the DRM fix included? And good to know that lineage stock pie doesn't have these problems, I'm pretty interested in doing that in the smarted way possible.

That's not quite correct, the camera now works with or without DRM. There are still a couple of other higher function softwares that are disabled, including the bravia engine (X-Reality, Super Vivid) and HD for Netflix. There might also be some audio extras that don't work as well, like DSEE HX and ClearAudio+, but I'm not sure and would like for somebody to correct me on that.

Yeah your right. Basically what he said is correct.

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.

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

Best Android 12 Rom So Far

Hi guys,
after almost 2 years with MIUI, Android 10 and Android 11 with MIUI 12.5, I would like to try a custom Android 12 rom before selling the device after the summer and buy something new.
As usual, there's a lot of custom roms. Even with A12. Onestly I would prefer to focus on a specific rom avoiding to try all the possibilities, this phone is my daily driver at the moment.
So I can see CrDroid, Evolution, Aosp, Voltage, Arrow... etc etc. Maybe seems a newbie question but which could be not a best rom but the first one to be tried ? Mainly I'm using the X3 to make call ( of course ), surf the web ( of course ), take photos to my children ( so the quality is very important for me ) and use it for GPS ( Mapy CZ and Here Maps ). With an eye on the battery duration...
Which A12 rom could be a good initial attempt ? Not so hard to be installed, I don't want to spend hours in bootloops or issues eheheh.

If you want something stable with good long-time support, there's only Lineage, ArrowOS and maybe AospExtended
If you take lot of photos, ArrowOS offers you unlimited storage in Google Photos. In Lineage you can add that feature using a Magisk module.
I went with ArrowOS for the unlimited photo storage and a few pixel features.
I have found a phone app that automatically records all calls and a Gcam that makes great photos.
Everything is better than MIUI really

On other phones, I was happy using AOSP Ext and CrDroid. What about this last one? I can start trying Arrow maybe...

CrDroid should be good as well.
The developer made a break of 2 - 3 because he gave the phone to his wife but now it continues to receive regular updates.

Could you provide the name of that phone app that records calls and gcam which makes great photos?
I am looking for exactly the same thing as the op. Right now on stock but it is so sloow

Here you go
Mod Edit: Link Removed
AOSP dialer has to be installed in Magisk.
GPay SQLiteFix is a fix to make Google pay work, has to be flashed in Magisk as well.
After installing Aspen (GCam mod) create a folder called ConfigsSettings8 on your phone's storage and paste the aspen2.xml there.
Start Aspen, double click on the black area of the screen and select aspen2.xml

@Noter2017: I'm curious here about your setup, so a few questions?
Is Bluetooth working alright with external audio devices?
Does GPS work reliably?
Is general wireless connectivity stable?
Can advanced reboot be enabled easily?
Is button navigation possible and can buttons be reversed?
I see you have Magisk, so no questions about rooting...

1) Bluetooth works fine for me. I use it with my Mi Band and a portable speaker. Personally I never had problems with Bluetooth, no matter which ROM I used.
2) I use GPS on a daily basis and it also works.
3) Works. With a speedtest get 400 Mbps on my 5 GHz WiFi at home (1 Gbps cable).
4) Can be enabled in Settings - Gestures
5) I use button navigation and didn't face any problems. You can revert the layout in Settings - Gestures - System navigation
Only problem I face after moving to ArrowOS 12.1 was that some backups made with Migrate didn't work. A few apps would crash immediately (Tailscale, for example) after starting (had to clear storage), my taxi app asked to verify my credit card again which didn't work. Had to remove and add the same card again.
Also customization is pretty much absent which might be a problem for some people.
I had a long free weekend, so I decided to spend a few hours upgrading. If the ArrowOS wouldn't have worked reliably, I would have changed ROMs to something else. ArrowOS 12 is EOL and I will stick with ArrowOS 12.1 till the end of the year. Really getting too old to do clean flashes all the time

I think CrDroid 12 (8.4) is superior. I use it with ANXcamera and Magisk
