SM-G389F Marshmallow Port to SM-G388F

SM-G389F Marshmallow Port for SM-G388F
Hello Everyone,
So we all know that the SM-G389F has Marshmallow as it's OS,
But when we look on the side of the SM-G388F, we still have Lollipop as it's OS, So I decided to port the OS version of the SM-G389F to the SM-G388F while configuring it to be compatible with it's hardware! :laugh:
I might need some help....
But we can start by Converting the Firmware Download to a Zip for the Custom Recovery to flash it
(Link to Download)
Thanks for Tuning in,
I will keep you all Updated soon! :fingers-crossed:

Hello Everyone,
I've wasted plenty of time trying to extract the SM-G389F Marshmallow Firmware but it was all for nothing. So now I am asking you all who own this device to flash the ROM link above using odin (https://www.sammobile.com/firmwares/galaxy-xcover3/SM-G389F/BTU/download/G389FXXS1APK1/114774/) and then creating a backup via TWRP including the system.img and the boot.img and sending it to me via Dropbox, Google Drive...
Anyway I would like to forgive myself for failing to do this operation without owning the phone because of the md5 protection, but now I will be leaving this part in your hands
Thanks in Advice,
Diamond26

For all intents and purposes consider the two devices as completely separate/different. First of all the got completely different SoC's (not revisions but completely different brands of SoC's). I started try to compile LineageOS (my sources are up on github), but I was facing completely obscure or unheard of errors that where difficult to fix and the amount of free time I have has changed so I more or less have stopped doing that for the time being.
I will be writing up all the info I know off the device but that task has gotten away from me at the moment due to computer problems.

Well in currently typing it from my Samsung xCover3, with the Marvell SoC, so it's the SM-G388F

Oh ok!
I was just eager to see if someone with a SM-G389F has come, maybe he could back up his 6.0 Stock ROM and maybe I could modify it.
That's why!

Please re-read my initial post in this thread, it's not possible. Your dealing with two different types of SoC's, so what your proposing is not possible, compiling from stock Android sources is (if you can fix every compile error)

Do what ever you want, you can still mess around a lot, you just can't transplant files from the value edition to the Normal edition.
There is some cool mods you can do if you modify system apks.

PX5 Oreo ROM

MTCD Oreo ROM Extract/Dump is here: ROM
An example of XDA teamwork - Thanks to:
 @ikerg
@xdamember2 @RedScorpioXDA
 @kumarai
Solution see post 159, thanks @kumarai
Process video again thanks to @kumarai
- note the approx 5 minutes of grey screen before "erase" is seen, proceeding first SDCard install of android 8 recovery files.
Team effort. Noted no BT with wd725 (integrated wifi/bt.)
Technical details of the 'Upgrade" - maybe useful in other upgrade scenarios:
- The Android 6 [update.img] [miniloaderall.bin] has been replaced with the Oreo [miniloaderall.bin] from the Oreo OTG ROM Extract.
- The modifed Android 6 update image is used to create a bootable SDCARD. containing the the Oreo Miniloader.
- SDCARD flashes the OREO Recovery images to NAND.
- With Oreo Recovery installed, .ZIP upgrade images can be installed.
Hi,
With resellers not proving a PX5 Oreo ROM image and no other member having OTG and as I have OTG and the jig/tools I could provide a ROM extract if the community provides a PX5 Oreo core board or complete unit.
Any supporters for either loaning a PX5 Oreo SOM or funding a complete unit?
If loaned I would extract ROM and return SOM within 2 days.

I will likely be able to loan a unit or SOM within a week or so. I noticed the SOM rev 8 (used in the Oreo hu) has more header pins than the earlier version though some may be blank. Is your hardware compatible?

A ROM Image has been availible here for almost a week now.

I'm a bit new to this. I see when I click the link there's an image and also a "download" button. If I download there's a jpeg sharp enough to read the silkscreen. (Unless Samsung is only allowing downloads to Samsungs?) I took the pic with my cellphone, I could also do one on the dslr.

I zipped the pic and now I should be able to attach it directly. Please let me know if higher res is required.

Does anyone know if the interface board provides better (i.e. multiple) USB ports now (i.e. not a single USB port split with a hub), and/or if the USB is better than the prior USB speed and power provided?
Ditto -- now Bluetooth 5.0?

So it is HCT PX5 SoM Rev8.0 Designed 2017-06-09 Interesting.

Why would you say that ? My MM 4Gb RK3368/PX5 SoM is also rev8.0.
@marchnz you could try using MTCD ROM Builder (here, needs a Linux machine : https://forum.xda-developers.com/an...re-development/tool-mtcd-rom-builder-t3475444 ) to make an image using the files in the zip. Theres the option to use FUSE which may get a round any partitioning problems.
I use Linux so I can make an image if youve got somewhere I can upload it to.
Maybe I ll try it myself, its just the hassle of trying to unbrick it if it bricks.
EDIT: just re read that thread and see youve already posted in it and used it on your RK3368/PX5, not sure it would work anyway as I think it requires a proper image already, dont think it can make one from separate images.

To create the image we need the partition addresses....so..unless we got an update with the classic .img or we could dump it from an already MTCD px5 under android 8.
I am going to receive a 4gb/32 px5 board with preinstalled android 8...but I don't know how to do for my pc to recognize it in order to dump the software...(I did before for android tv under rk3288)
Any suggestion?

But would we need the partition addresses if we create a FUSE ROM ? - MTCD ROM Builder will make one big partition surely ?
I could try using an MM RK3368/PX5 image and adding the separate images from the Oreo update.zip.

Currently there is no GSI working on this model AFAIK. Wait for device specific ports instead.

I am using Project elixir for almost 2 weeks now. So far so good.
I suggest you dont flash it but instead usi it via DSU. Autobrightness is not working, fingerprint too. There are gcam ports wich are also compatible with our device. Battery life is better than miui. Even adding a card to google wallet works fine, until a reboot.

You shouldve just used google to understand better. But basically its a subsystem method wich was implemented to allow a/b partition devices to be able to run gsis' for testing purposes, without the need of flashing and deleting the original os. Think of it as dualboot for android. The only thing is that if you're using it via dev settings, you dont have the choice of selecting what to boot, but your device will directly download google's official gsi (wich is not very functional and its ugly).
Thats why you just need to download the DSU Sideloader app from PlayStore. The app will do everything with a gsi of your choice if you follow the instructions.
The only thing wich is mandatory is that the BL of your device must be unlocked in order to use dsu.
There are videos on YT showing this. If you want to try the gsi I mentioned, download it from their website.
