Installation Instructions
Make sure you have a second partition on your SD card before flashing!!!! This can be created with minitool partition wizard on Windows or gparted on Linux.
If on a BML rom (stock-based GB)...
0. Read "Things to take note of" below
1. Reboot to recovery
2. Make sure your version of CWM is at least 5.x
3. Install zip. It will reboot a couple of times, don't be worried.
4. If you want root or Gapps, flash them now
If on an MTD rom (CM7 and all ICS+)(I tested CM9, CM10.1 and CM11)...
0. Read "Things to take note of" below
1. Reboot to recovery
2. Wipe data, and cache paritions (just in case). If updating to a newer build, you can probably skip this step
3. Install zip
4. If you want root or Gapps, install them now
The first boot can take several minutes. Be patient. If it takes 10+ minutes, pull the battery and reboot to recovery.
Things to Take Note Of
Humberos (the i9000 maintainer) has moved on to different projects which means no first-gen Galaxy S devices are being actively maintained. Builds may break at any time!
I actually have a T959P, not a T959V... It was released by Telus in Canada. It is a very similar device (I can run ROMs for the T959V with limited problems - ie sometimes I get wakelocks and the gps never works), it has a different GPS chipset and also uses different cell bands (but I can still use your guys modems but I lose access to the 850Mhz band). I have created a build specifically for the T959V as best as I can guess and also provide T959P builds.
The USB connection is MTP and not mass storage as Omni has removed mass storage. In recovery there is still an option to mount as mass storage device.
This build is very close to the official omni source code. This means that the recovery is TWRP and there aren't any added "features"
In order to get it rooted, you need to install SuperSu.
Gapps reportedly slow down the device significantly so tread carefully.
Backup Backup Backup! I'm not responsible for you losing any data.

Thanks Time!
This would not have been possible without the following people:
Thanks to humberos for bringing Lollipop to the first-gen Galaxy S series. This would not have been possible without his work.
Thanks to FB and Dao for their work on the CM-11 device tree. I used several of their fixes.
Thanks to noiphonehere for his device trees and kernel, most of my work was based off of his.
Thanks to bhundven and the other members of teamacid for their work on the aries kernel.
Thanks to all others that have helped get this phone to where it is today!
Thanks to vcmerritt. A name you're probably not familiar with, but he was the only one to create something for the T959P and without him I'd still be on stock...
Build your own!
Follow the instructions at http://docs.omnirom.org/Setting_Up_A_Compile_Environment using the android-5.1 branch
Before doing a repo sync, put the galaxy_s_series.xml file from the Download folder in .repo/local_manifests folder of the source tree.
After syncing the source, open a terminal and in the directory where you downloaded the source code type "source ./build/envsetup.sh" and then "brunch galaxys4gmtd"
Changelog
Changelog for 07/03/2015 Build
Newer Omni source
Added volume controls and flight mode toggle to power button menu
Added Bigmem option. This increases available RAM by ~20mb but breaks 720p video recording. Humberos created the kernel setup and I integrated a toggle for it into Advanced device settings.
Selinux is now in enforcing mode. I had to modify the GPS startup to have any chance of getting here. Please let me know if it still works/doesn't work/never worked
Notifications are sometimes wonky. To fix, in Settings, go to Performance, then Advanced. Select Force high-end graphics and reboot your phone.
Changelog for 2015/07/20 Build
The data partition is now the second partition of the SD Card as opposed to internal storage
Gapps now work. If you get error 461 when installing from Play Store, a full data wipe should fix it. You can try experimenting with clearing data for the Play Store and/or Play Services or removing and re-adding your Google account if you don't want to do a full data wipe.
HSPA vs UMTS settings in DeviceSettings has been fixed
High-End graphics are forced by default to fix notification issue
ART parameters have been tweaked
Miscellaneous other tweaks, see my Github for details
Changelog for 2015/07/24 Build
Stabilized bluetooth connection
Fixed typo in GPS initialization. Does it work?
Added ability to use f2fs file system on /data. Supposed to give better performance
Added force fast charge and touch wake to kernel. Touchwake is accessible through its sysfs path, fast charge through Performance Settings, BatterySelinux currently denies these requests...
Changelog for the 2015/07/29 Build
This is a maintenance build. Very little has changed
Some more RAM freed (disabled some debugging stuff, TV-Out driver, IR driver)
Sepolicy updated for fast charge and touch wake
GPS initialization tweaked - unsure if works. If it doesn't, a dmesg would be appreciated
Changelog for 2015/08/02 Build
SElinux changed to permissive - this build only
GPS sepolicy changed - unsure if all necessary things are implemented
Changelog for 2015/08/13 Build
Selinux back to enforcing. Thanks to @anoymonos for the dmesg and @DerPugNa for offering to send me one as well
Fixed encryption
Changelog for 2015/08/31 Build
Updated Android version (5.1.1_r5 to 5.1.1_r12)(upstream Omni Change)

Awesome work @xc-racer99!

Wow, bringing this ole device back from a coma here. Nice to see someone else willing to work on lollipop for this oldie but goodie. Keep this device alive man.
Edit: If you are in need for some GFX for this thread, let me know and I'll see what I can brew up for you.

I hope I can keep this great little device going a little longer, however it will probably get tough. I did a repo sync earlier today and things are starting to break. The last few builds haven't even booted. With humberos no longer maintaining the i9000 and aries-common, I've had to fork the aries-common repository to try to keep going. The only upside of this is that I now have a little bit more freedom and can add things in if I want to.
Thanks for the offer of the graphics. If I can get a new build working, then I'll probably take you up on your offer. I think I've traced the problem but I'll have to wait and see...
For anyone that is trying/has tried this out, I'd be very curious on the status of the GPS on the T959V. I'm interested in creating the sepolicies for it so we can put selinux into enforcing mode but I don't want to go to the effort if it doesn't even work right now.

I've downloaded the zip and one of the smaller Gapps packages...won't be able to flash until early next week...I'll be out of town...will post results later...thanks for keeping this phone current.

New Build Uploaded!
Download is still at the same link as before, just use the 2015-07-03 build
I managed to find out why my new builds hadn't been booting - it was because the syntax for using a custom kernel toolchain had changed.
Anyway...

Selinux is now in enforcing mode. I had to modify the GPS startup to have any chance of getting here. Please let me know if it still works/doesn't work/never worked
On another note, I've had a look at re-implementing TV-Out support. It doesn't look promising as several of the functions in the android frameworks that it used have been tweaked.... Still working on it but don't hold your breath.
Also, if somebody could test dock audio that would be appreciated. I don't have any way of testing it. If it doesn't work, I do have an idea on how to fix it (for those interested, another almost-aries device, the Infuse 4G, had to modify things slightly to get it to work. I would try to emulate their solution).

Omg download nowwww....thanks my friend

Alright, I'm having some issues on the latest build with notifications and the lockscreen. I'm still working on tracing down the reason for the problem...

Hello, im a user of a t959v. And I've been using this rom for three days. Everything is fine and very smooth on this rom except that, I can't install anything from the playstore. I always get (cannot install app due to an error 963). And Ive tried all the gapps, even the new link provided but still no luck.

Good to hear that that's its (mostly) been working for you. I was hoping that the gapps problem was just me
Out of curiosity, which of the alternate gapps did you try?
A brief google of the error brings up a couple of possibilities...
Try an older gapps version. The ones from devloz on the i9000 thread devloz and the oldest revision for 5.1.1 are probably your best bet. Please be aware that Google Play store will automatically update!!! In order to prevent this, you will need to create a folder called "com.android.vending-1.apk" in /data/app (use a root explorer such as ES File Explorer or adb if you know how). If a file with that name already exists, delete it first.
Another thing to try would be to unmount your sdcard first before trying to install an app. I know, its a terrible work-around but it should work. This is because the error is that Google Play is trying to save some data on your sdcard but then for some reason it fails (I'm not sure why).
I'll hopefully get around to seeing if its a permissions problem after I find out what's been causing the issue with the notifications on the latest build.
P.S. Does the GPS work?

Early update...
...ROM flashed fine...a little slow to boot...about 3 minutes...but it booted.
...Gapps flashed fine...used 20150513_5.1.x package
...Installed Super SU (although I don't think that's necessary) and TB.
...So far only gave a quick test to camera and web browser...no problems.
...Am now in the process of re-installing user apps and data from TB...this will take a while.
When I'm done with that, I use Link2SD to link most of my user files to the SD card. After that is all set up, I'll test stuff like GPS, root access, etc. I'll post back later...maybe tomorrow.
But so far so good.

OK...I did some testing tonight and here's some results.
Working:
.it boots
.root
.browser
.playstore
.camera
.link2sd (about 180 mb free in internal)
.camera
.wifi
.email
Nor working:
.bluetooth
.google search/voice search
.just about all the rest of the Gapps
.tons of force closes including Maps so can't test GPS
Won't be able to do anymore testing until next week.

Alright, thanks very much for the update. I'll do some more testing here and see if I can solve anything. For me, bluetooth file transfers to the phone work but not from the phone.
I've been looking at the notification "error" where the lockscreen notifications do not appear correctly. It appears to have been introduced upstream with a merge. I'm having difficulty finding out exactly what changed and since no errors are being thrown in the logcat, it could be a while...
For testing the GPS, there's an app from the Play Store called GPS Test which does a nice job of showing satellites and whether or not you have a lock on them.

you're the man!
nice one! its nice that this device are still alive.! and now were on 5.1

No, it should be Humberos is the man! I basically re-hashed his code for the i9000 and used bits and pieces from people like Bhundven, noiphonehere, maxfierke, Dao, and FB to get things to work properly.
For a status update, I figured out the lockscreen notification problem. I have a new build being made that I hopefully will be able to upload in the next couple of days (internet dependent). TV-Out looks totally broken as the proprietary blobs no longer function. I don't have the know-how to make ugly hacks to get them to work. The new build will have SElinux in enforcing mode and have the different GPS initialization (like the last build) until someone tells me that it doesn't work
Uh-oh, looks like I jumped the gun.... Having problems once again

Any updates on getting the play store to work? I have searched, downloaded, and tried every gapp made for 5.1. I found that I can load any app on the rom, if I get the APK version of it.

Darn, so its still not working. Not surprising. I've been struggling on the notification issue and am at my wit's end as to what the problem is. I don't think its only our phone as several i9000 users have been reporting it as well. Whether it is only the first-gen Galaxy S series that is having the problem or not is anyone's guess. My programming skills are insufficient to fix the issue!
I'll have another look at gapps over the next couple of days and see if I can figure out a combination that works 100% of the time.
I'm assuming the error message is still 963 or does it silently fail now? Its probably related to the fact that we have only an external sd card and no internal sd card like most devices...
All the problems with the notifications that I've found are:
Only one notification will show up at a time
Large notifications such as the music player do not render properly. They are cut off at the normal notification size and occasionally it seems as if there are two layers there (one for the small version, one for the bigger version) (see attached picture, taken with VLC as the media player, but also appears with Apollo)
Notifications don't always show up. A little icon appears in the top left corner of the status bar but no notification is present. Seems hit or miss
The words No notifications appears in the lockscreen just above the clock when there are no notifications. Otherwise, a notification (and only one) which can't be clicked covers part of the clock

[ROM] iPioneer Slim 10c v0.1 for LGV521 - Rooted, busybox, init.d, debloated, etc...

ROM Ipioneer Slim 10c v0.1
A light, clean & faster rom!!!

***/
iPioneer Slim 10c v0.1 is a light, clean and fast custom rom designed for the Lg G Pad X 8.0 (T-Mobile variant only) and it's aim is to become a replacement for the default system of this device.
iPioneer Slim 10c v0.1 it is light because it only takes 519.8Mb of disk space which is a big difference when you compare the 1.2Gb of a stock rom, it is clean because it only contains the essential apps to make it work properly and it is faster because the whole system have been 100% optimized.
iPioneer it have been designed with the User Freedom in mind, it only provides you with the basic OS so you can do what you need to do on top of that.
Features:
Based on stock (10c)
Rooted
Busyboxed
Init.d Support
Extremely debloated (very serious)
Deodexed
Zipaligned
Nova as default launcher
Installation instructions:
Download the rom to your desire location (link to download to the end of this post).
Boot into Twrp recovery and do a standard wipe (factory reset).
Install the downloaded rom .zip.
Reboot the device.
Be patient, is going to take more time than a regular stock rom to boot into the system, at first is going to be stuck at T-Mobile logo but after few seconds is going to enter into App Optimization mode and after that you will be able to setup your system.
Enjoy it.
First things to do after you install this rom:
Add your google account (if you didn't complete that step at the first setup).
Download your favorite app manager (Rom Toolbox, Titanium, etc.).
Freeze the application called App Updates in order to stop the system update beacon for OTA. I removed 3 core apps in order to stop OTAs but it seems to be very integrated with the system, there is no way I can remove it from the rom without breaking the system. This is the most practical way to my knowledge right now.
Optionals things to do after you install this rom:
You can uninstall Nova Launcher if you want as is not part of the system apps, but before you need to install your favorite launcher. If you don't install another launcher and remove Nova you will have a broken system and most likely you'll have to re-flash the rom.
On purpose bugs and missing options:
On purpose bugs are bugs that comes when you remove a functionality from the system but it can not be removed from a third party component, example: LG VPN app it has been removed but the options remains in the Settings of the device and when you tap that option you will provoke a crash event, the way to resolve this is to decode the third party component (very difficult) or reinstall the missing part (in this case the LG VPN app).
iPioneer Slim 0.1 it comes without some apps that can not be removed from the system setting options, this is like that because I believe that these apps are not necessary for all people, if someone need them they can be downloaded/replaced from the Play Store or I will provide a flashable file with these apps so you can install them.
On Purpose bugs (located at settings):
From the Share & Connect menu:
File Sharing that contains BLE and Android Beam doesn't work, package SmartShare it has been removed.
Media Server (DLNA) doesn't work, package SmartShare that also contains SmartShare.MediaServer it has been removed.
Lg Airdrive doesn't work, package LGAirDrive & LGAirDriveSettings were removed.
From More>VPN menu:
LG VPN doesn't work, package VpnClient_LG it has been removed. Basic VPN it works.
From Display menu:
Home screen doesn't work, packages LGHome, HomeSelector, LGHome_Theme_Optimus, com.lge.launcher3, com.lge.launcher2.theme.optimus were removed.
If you need these options to be available on your system just download these app on Play Store if they are available or just wait until I have ready the System Apps flashable zips.​
Missing options (located at settings):
Smart Cleaning not present, package LGSpringCleaning it has been removed.
Cloud (cloud integration in settings) not present, package CloudHub (maybe dependant on SmartShare package) it has been removed, please also note that this cloud integration it was integrated on the stock File Manager, so... if you want a full integration of the Cloud service on settings maybe you will have to install the stock File Manager provided by LGFileManager package.
From Backup & reset menu:
LG Backup is not present, packages LGBackupLauncher and LGBackup were removed.
From About tablet menu:
Update Center and its content (App updates & System updates) is not present, packages com.lge.appbox.client (app updates), com.lge.updatecenter & LGUpdateCenter (main menu for updates) were removed.
If you need these options to be available on your system just download these app on Play Store if they are available or just wait until I have ready the System Apps flashable zips.​Flashable zip with system apps:
Coming soon when I have a free time.
What to do if you get the OTA notification:
Freeze the app called App Updates with your favorite app manager.
With your favorite file manager go to /cache and delete the update.zip (the downloaded ota).
Tap on Restart & Install button on OTA pop-up, the pop-up it will start counting to 0 in order to restart but your device won't restart because there are 3 core apps removed from this rom plus 1 app that you just disabled (all these 4 app controls the OTA), the notification is just gonna disappear, push recent button and clear the ota pop-up window.
Bugs Report:
If you find a bug in this rom just notify me about that in this thread, please, just use the title as "Bug Report" so I can pay close attention to that, my time is very limited. Thank you.
Feature Request:
If you want a feature to be added into future revisions of this rom just notify me about that in this thread, please, just use the title as "Feature Request" so I can pay close attention to that, my time is very limited. Thank you.

How fast does it run compared to the stock rom?

How fast it can go is a subjective matter:
It will depend on hardware lifetime span (how you use it and how other people use this tablet).
It will depend how much apps and content you put in it (the more things you download the more slow android is gonna be, this is kind a Swap area).
I did not do a benchmark, when I declared that is faster than a stock rom is because that speed response enhacement it comes based on the Deodex and Zipalign process. It can be or maybe not noticeable to your eyes but based on deodex and zipalign process is for sure that is faster than an odex and not-zipaligned rom.
The best answer is that you need to try it on your own and see the difference.

Poll added at the beginning (not visible in tapatalk or xda app).
Please only select the apps that you really need or you really think that should comes with the next revision of iPioneer Slim rom.
This will help me to build a better version with features that users needs.

C'mon guys... only 3 users have use the poll...
I need more data background in order to release a new version of the Slim line version (may be the last one).
All V521 users please contribute with this.
Right now I'm testing a new build that it seems to have success stoping ota download and notification & I have removed even more bloat background packages.
As of today I start the syncing process of CyanogenMod for our device, so all I ask is that V521 users vote in the poll so I can build and release what I think it would be the last Slim version (iPioneer Slim 0.2) based on users needs.
Once I start the developtment with CM I will not pay attentions to the Stock & Slim version until I finish with what is gonna become iPioneer CM 13.
Thank you for your attention guys.
BTW: sorry for my english, I try so hard to write all this in a good way. Arriba Mexico Papa!!!

The reason is that the xda app can't see the vote going on.
Personally, I will be excited to see a cm/aosp custom build, which will sure draw much more attention.

Another reason is not many users are interested enough in a slimmed stock rom. The benefits of a slimmed stock rom may include less system storage usage. But the free uped system storage is not accessible for users to use as data storage anyway. Speedwise, I wouldn't expect noticeable improvement from a slimmed stock rom. As a result, the benefits of a slimmed stock rom is not enough to draw users' attention or interest.
I am a flashholic but I actually not interested in slimmed stock at all because I already have root.
I personally advise you to not spend too much time on modified stock rom.
I appreciate your work and look forward to your future possible cm rom, which I will definitely try it out and will draw many g pad x users here. And don't forget there is a bounty for custom roms like cm.

Another reason is not many users are interested enough in a slimmed stock rom. The benefits of a slimmed stock rom may include less system storage usage. But the free uped system storage is not accessible for users to use as data storage anyway. Speedwise, I wouldn't expect noticeable improvement from a slimmed stock rom. As a result, the benefits of a slimmed stock rom is not enough to draw users' attention or interest.

You are right about working in a stock version. The reason why I'm doing this is because we all know that CM most of the time has bugs, bluetooh problems, camera issues, data conectivity troubles, etc...
Sooooo, if the version of CM I'm going to compile it results with many bugs there is gonna be the option to go back to stock slimed or stock bloated.
I can build a CM verion but Im not the kind of guy who inverts his time in CODE MODIFICATION, so hopefully the build it comes with no bugs at all or at least no major bugs.
The other alternative is that I can sync, compile and build and one more guys can do the bug fixes.

That would be great! I think if you took a poll most people would prefer a CM build to a slimmed down stock build.

Yeah, I know that. Wish me luck.
Right now I'm stuck trying to get the Blobs for this device and compiling the kernel so I can build the CM recovery, once I have the recovery done I can start compiling CM and start testing.
I'm trying to by pass the kernel (as is not need it right now to build the recovery) but for some reason the system is demanding an standard and working kernel... weird...
But honestly speaking is gonna take lot of time. So be patient guys.

There is already a TWRP recovery for v521. Why you need to compile cm recovery?

Ik, is just a prebuilt because our device doesnt have a device tree or structure already, so making this at first is gonna help me to buil the cm zip.
Is not need it if a device tree already exist but not in this case, just see it like a pretesting of code for this device.
When I try to compile this recovery things are gonna break so you get info of what is missing, what you need, log, etc... So you fix everything you can in this step and then you build the cm.zip in a better way (less issues).

device tree has been around for a while, it obviously will need some renaming to work for cm source but its a good foundation to start with.

These are your device tree for twrp 4 b3 right?
Let me see if I can work with that, I was almost done building the cm.recovery and fixing some boot.img issues but if I can take your files that would save time.
Did you forked that device tree or u just build it from scratch?
If you forked them, from what device?
I was thinking on pulling the v500 just to figure out some sort of missing info I havent been able to catch from ramdisk.

i built it from scratch, id be careful looking too much at the v500, it's a snapdragon 600 SOC which is very old and is a quad core. the 615 in the g pad x is octacore and much newer. even the ramdisk is going to have big differences in how its handled.

[Treble GSI] [Umidigi One Max] GSI Experiments

Now that the Umidigi One Max has TWRP, it is now very easy to flash GSI ROMs.
I will try to keep track of different GSI that works (or not !) here, alongside with bugs. Testers are welcome !
I highly recommend GSI based off phhhuson's work, as he did great job to fix MTK issues. Some other GSI may work better. We definitely need testing !
10
Apparently it works as shown here: https://forum.xda-developers.com/showpost.php?p=80319007&postcount=13 credits to @4ctiv_
9.0 Pie
phhusson's AOSP :
Everything works as expected. Notification bar is of the wrong size, may need to create a patch for it. Tethering doesn't work with data ON !
Camera is good ! All cameras are recognized. Fingerprint sensor OK. Torch not working under 15% like in stock, this seems like a hardware thing.
Ongoing calls and SMS will not work first boot. Just reboot and it'll work.
Magisk 19+ doesn't show root prompts. Fix here
Pixel Launcher crashes, but it seems that it's the only google app that doesn't work. Google Phone works.
NFC doesn't appear at all. There is a fix with magisk tho ! See here (NFC4PRA)
ctsProfile doesn't pass. Using MagiskHidePropsConfig fixes the issue, but choosing "vendor fingerprint" bootloops​
Testers needed
8.1 Oreo
Testers needed
Do not hesitate to post what you find or your testing.
NOTE : Installing a GSI can be done via 3 methods : TWRP Image Flash, SP Flash Tool, or fastboot (needs unlocked bootloader)
For the first two methods, unlocked bootloader is not required ! TWRP can be flashed via SPFT aswell.
Enjoy your beautiful and modded phone

Make sure to check out my guide on installing GSIs at https://forum.xda-developers.com/android/development/umidigi-one-max-custom-rom-modding-t3942521/

I downloaded system-arm64-ab-gapps-su.xz, extracted the file, booted into TWRP, did a full wipe, and installed "image" system-arm64-ab-gapps-su.img. TWRP asks which partition to install it to. I selected "system". However, after install I go to reboot, and TWRP complains there is no OS. Am I missing something?
I did a complete backup in TWRP of all important partitions first (nvram, modem, system Etc.), so going back to my stock setup was not difficult. Those trying this, backup all important partitions from TWRP on to microsd!

For everyone, make sure you download AONLY images, not AB !

I posted this in another forum, but for the life of me I do not know what is causing this issue. I installed RR rom located here:
https://get.resurrectionremix.com/?dir=gsi/
system-190120-arm64-aonly-vanilla-nosu.img
I also install, Gapps (pico), and Magisk.
It runs great, for the most part. However, if I start streaming a video from any app or start streaming music, after a short amount of time my Umidigi One Max:
A.) Announces, "Powering Down"
B.) Boots directly into TWRP
C.) If I reboot, it again boots directly into recovery. Almost as if the partition became corrupted.
D.) Try to recover a backup I made in twrp, reboot, again boots straight into recovery.
E.) If SP Flash can communicate with the phone, I can usually push all the stock images back to the phone. If not, I have to push the images via fastboot with my Ubuntu PC.
If I do any other CPU intensive task under a GSI ROM, it doesn't have this issue, only when I stream video. I haven't tried any games to see if it causes this behavior.
I have tried multiple GSI Roms located here too, same problem:
https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list
I do not believe the device is overheating, it's usually around 32-34C from the TWRP menu at that point. I really like the RR Rom, but if I cannot figure out what is causing this, I'll have to stray away from GSI for now.
As a sidenote, this issue of the device suddenly powering down after starting to stream a video, does not happen with the stock ROM. I am kind of at a loss on this one.
Weirdest thing I have experienced running a custom ROM.

Yeah it happened to me sometimes as well... The phone goes straight into recovery and then never goes to system again. I haven't found the cause of it.

Did you try the NFC fix for the one pro (I got it from the umdigi forum one Pro and then the thread custom ROMs)

phhusson's AOSP is mostly good. But I noticed the wifi often gets disconnected and has performance issue too.

I don't get any performance issue. The only issues is that some ongoing calls doesn't come, and sometimes 4G totally glitches out. Other than that it's pretty much all.

@ _cab13_
i cant find the vendor folder in twrp in the mount section or in the file manager.
what have i done wrong? ok i started from scratch and then it worked porfectly
thx you for your work and help

Engineering mode access or work around
On the 9.0 ROM I cant seem to access engineering mode via the keypad, I need to sort the handset speaker out. Is there any other way to access it or some way of tweaking the voice settings through the shell?
Any help would be appreciated.

Please help

did you use the a only or ab image?

I've tried flashing multiple android 10 GSIs from the phhusson GSI wiki list.
I've tried phhusson's AOSP ROM, CAOS, Lineage 17.1 and POSP. It seems like they all freeze at the splash screen and get stuck loading forever (confirmed, I left it on all night last night). I've tried disabling force encryption, I've tried not installing magisk. Not really sure where to go from here with Android 10.
I've also tried Android 9 with much more success: it boots, it works, but the only thing I can't seem to get is NFC. Has anyone found a way to get NFC to work on any android version with this device? Or do I have to go back to stock android 8?
Thanks!

I'm in the same boat bro. I've just tried both the latest phhusson AOSP 10 ROM as well as an older version of the same ROM, and both time I get caught in a loop after install. Completely wiped beforehand, tried installing with and without Magisk/Disable-Force-Encryption. Going to have to bring it back down to Android 9. I wonder how 4ctiv_ got it working?

so first you have to no encryption then erase and format data
flash android 10 arm 64 a without gapps build (image) to system i use havoc 3.5 and everything exept nfc works
then install gapps (it failed for me so i had to resize system in twrp and install gapps again
last step is to flash the custom phhson magisk
then just reboot wihout wipping

Thank you so much for your work...
Hi, I'm a long time Android user and I used to code apps, if I can be of any help please let me know but I'm now disabled wheel chair user with dystonia so I find it extremely difficult to type now so I use voice to text... I really enjoy using the umidigi one max it has the storage and usability of a much more expensive phone, also functionally for me the wireless charging and NFC make my life so much easier as I find cables akward and payments at shops much easier.
I read about the Treble programmea while ago and recently read this article and if it is possible to get the NFC working on this update, I will be so greatful as it will extend the life of this great phone for me.
Good luck with your work and thank you in advance.

This is an unofficial Pie build for the S3 LTE (i9305) based on LineageOS 16.0.
!! Please note that all thanks and credits go to @ChronoMonochrome because he ported the necessary changes to t0lte and got Pie to work for that device, especially the kernel thingis!!​
And below is a quote from his release, where he mentioned in his t0lte thread all the involved devs and credited to all the people helped to get pie running for our "old" devices.
This work is heavily based on works of PoisonNinja, Option58 (thanks for device tree, kernel and device patches for LOS 14.1).
A full credit for Pie bringup goes to rINanDO (thanks for device tree, kernel and device patches for LOS 16.0).

nice job dev @rodman01
Well done

Hi, thanks for your great job!
Almost features are fine. I recognized only two stuffs for now.
** 1) phone call **
I set up a VoIP phone app on a phone which was flashed this rom, and called another phone.
The echo back is heard on the VoIP app side, but I could not hear the voice I talked on the receiving phone.
Do you think above phenomenon is related your attention "Call recording, call forwarding and else" or not?
2) FTU was appeared a few times
When I started using this rom, FTU appeared twice or more after I went through FTU.
But as for now I don't see FTU anymore. Thus, this is a trivial issue.
Anyway, I am looking forward to seeing the next updated version!

small update
Hi There,
gapps pico are working, but graphical glitches are occurring in youtube app, youtube browser is working fine, google films is working fine.
Bluetooth sending and receiving is working, device name is still wrong, shows still Galaxy Note 2, which does not matter and can be changed in settings manually.

Fantastic . I will keep an eyes to this.
thank you so much !

trying the rom
What file should I download from the root link ?

new build is up: 20200122
Hi There,
made a new version nd its uploaded now.
Based on yesterday evening leo sources and small update in device source.
- Youtube App is now working and Google films too
No other bigger changes.
And since there are no reports yet about serious problems, I changed the status to from Beta testing to bBeta.
Whats App, Instagram, Facebook and other messengers as well as other social media apps needs testing and would be glad, if someone can report back.
GPS most probably won't work. I am getting no satellites and no fix

Im trying to install this custom rom but everytime I got stuck on LineageOS loading logo forever. Anyone have this problem too?

some problems...
on 20200118 ver.
1) following apps sometimes crashed.
LINE, Adobe photoshop express, Amazon Shopping, Proton Mail.
I felt these apps often crash especially when a first invocation and registering an account to every app via network.
After registered my account, crash frequency decreased.
2) following apps couldn't be installed by Google Play Store
LINE, Google Drive, Google Spreadsheet
* For LINE, I installed older apk manually.
I cannot download 20200121 ver. via AFH yet. I'll test further after the rom is updated.

Have you wiped out data, cache, and Dalvik cache before install the rom?
If you didn't yet, try it but ALL OF YOUR DATA WILL BE CLEARED!!
Be aware of what you're doing and do everything at your own risk.

I got the same issues .
I keep it stuck there for almost 40 minutes 2 times but it didn't work.

@rodman01
I intend to flash and test the ROM this weekend. However, I've issues to download it as AFH doesn't find any mirror. Do you have another DL available?
Another question: Anything against not to use your given and linked root solution but to use Magisk? As you provide a separate root solution, I assume Magisk is not incorporated into the ROM.

Depending on from which rom you are coming, it could be better to flash an other custom rom first. You can try RR or cm14 and test whether this is working. And if yes, that follow the steps in op for a new and clean installation. It can also depend on the recovery you are using.

Sorry for the issues with afh. I will try to fix it with uploading the version again.
@Oswald Boelcke no specific reason why I linked the root to leos. Magisk should work as in previous versions. I tested it a couple of weeks ago with a prototype version and it worked. So its worth to try magisc, yes.

Rom new uploaded, afh should find mirror now. Sorry for circumstances:

I could install all your mentioned apps via google play store. It last a bit, the download is not fast, but worked on my end. Amazon is crashing on my side too, the others not, but I haven't tested them much, because I don't have accounts or ids for for example photoshop express or want to create or share my phone number or personal details.

By flashing this you take responsibility of anything that happens.
Process at your own risk!
Special thanks to Exynos5420 team and LineageOS for all the sources.
Use SM-T900 build at your own risk. I can't guarantee you it will work, because I have no device to test it on.

Damn!! Just installed and working.
Really good work! Thanks!!!!
i found a bit problem, starting android it loops between voice assistant and set lock for tablet. i needed connect earphones with microphone to finish voice assistant configuration and then it continued.
Thanks for rom!

@TechDriver can You build a LineageOS 17.1 ROM for SM-T900 who is used the same Exynos5420 CPU?
If is necessary I can be a beta tester.

Did you install on the t520 or the t900? Did you really go back to the Samsung official build first? (I'm on t900 lineage 14.1)

You don't need to go stock, just backup your data using TWRP and follow installation steps above. I am little unsure about build for T900 because I do not own this device, so I wait for someone who can report me if it works or not.

@TechDriver Clean flashed 17.1 over 14.1 without flashing stock on T900 using twrp-3.5.1_9-0 and it flashed great. I plugged in a headset but my Hey Google was already recorded and didn't give me any trouble. I don't know what would have happened if I hadn't plugged in the headset. Play Store does not recognize my already purchased apps. This usually means something is not right and I wonder if not flashing stock first is related to this? Can be very smooth but can be a little glitchy as well. Still experimenting and trying things. Bluetooth Keyboard and Mouse work great. Thank you for this.

It has probably something to do with missing play protect certification. I will try to sign device for certification but need someone with T900 who will cooperate with me. For now easiest way to avoid problem is going to browser version of play store and installing paid app to specific device from there. It should work fine. Also thanks for testing and reporting that T900 build works.

Just for understanding, these are still 32 bit builds, vor did you switch to arm_64?

@TechDriver SELinux is not enforcing. That may be why Google Play does not recognized my purchased apps. Installing purchased apps trick from Google Play on the web worked as expected. Booting tablet, it does not accept passcode on the first try, but works on second try. This is repeatable. I will be happy to be your T900 tester if you make some test builds.

Exynos5420 is 32bit SoC. It doesn't support arm64

@TechDriver The pass code works the first time if you are not impatient and click the accept arrow before the last number changes to a dot. There is a delay and the passcode entry is laggy and you have to be patient for a few seconds. twrp-3.5.1_9-0 is able to back up and restore 17.1 with no problem.

@TechDriver The first login with PIN after booting will fail. The second and future screen saver logins will work with the caveat that you are patient until the last number turns into a dot.
Pixel launcher does not work correctly with mouse clicks and has a focus graphics glitch. It works right as long as you don't click the mouse. If you click with the mouse to open a group of icons in a folder it leaves a residual grey box behind. You can see this same grey box where the PIN numbers appear on the screen saver as well. I changed to Nova Launcher and the problem improved with the grey box occurring if I open the icon folder and actually open an app but then disappearing on moving into a different folder. This is all with the exception of the PIN screen saver which causes the same grey box on both launchers. Something is not quite right with the graphics using mouse.
I mostly use this tablet with keyboard and mouse and Nova is more acceptable now. I prefer Nova Launcher anyway as it is much better at using the whole screen.
The camera is extremely basic. Open Camera seems to be an improvement. Any Google Camera port available that might work?

Just to make things clear, I am not developer of code and not skilled enough to make changes in it. For this job, there is team exynos5420 and other cool contributors to make device sources. I use their device sources from exynos5420 and LineageOS github to build together final product... Rom.zip you install on device. I can't fix bugs, i only can wait until some contributor fixes it and I will build rom with fixes and updated security patches included.

@TechDriver Got it. Will the devs be watching this thread for feedback?

I am unsure about that, most of original devs for n2awifi and v2awifi stopped developing code for this devices. Keep an eye on exynos542X github for new commits.

First of all I want to thank you for the this ROM.
I tried this ROM with the latest TWRP version for two days and I want to inform that it is working good with some small non-conformities:
I had some random reboots and the system crashed and freezing
After rebooting there is a long time after entering the unlock pattern, sometimes it is necessary to enter the pattern several times.
I have installed ROM, gapps nano rebooted and after that install Magisk 22.1
my model is SM-T900

@TechDriver ,Great work on this build! Never thought I would see this accomplished. Many thanks and keep up the good work. This is fully usable with Nova beta 7.0.27.

Works perfectly on my T900, many thanks! Keep up the good work!

Can you provide a link for this latest Nova beta? APK mirror seems booked.
Nova 7.0.27 Works smoother and scrolling and moving icons is better. PIN screen on first login is same problem and will not work on the first try. Mouse clicks and mouse related screen painting remains an issue. If you don't use a mouse you may not notice any problems other than first login. Come to think about it, 7.1 had issues with the mouse most noticeable when I used Collabora and I had attributed it to the app.
