I have a J7 Pro (J730G/DS) and I was wondering if its possible to install ANY rom that is 64bit as my CPU does indeed support 64bit but my OS is only 32.
I want to use this smartphone as an emulation device but most modern emulators such as Citra and Dolphin require 64bit Android
if its possible, can anyone link a guide on how to change my rom to a 64bit one?
I recommend installing a custom Treble rom, as they are all arm64.
For that I recommend first to create a Vendor partition(with recovery) using the file Exynos7870_CreateVendor_2.0.zip(download from here https://forum.xda-developers.com/galaxy-j7-2017/development/treble-project-treblue-j710x-t4098875)
Then recommend you to install this ROM: https://forum.xda-developers.com/galaxy-j7-2017/development/unofficial-crdroid-6-7-t4119505
And you will have a 64 bit OS.

Thank you for the help, do you maybe have a guide for me? never installed a custom ROM before
[GUIDE][J730X] A beginer's guide to installing custom ROM on Samsung Galaxy J7 2017
In order to install a custom ROM, the general steps are to: Unlock bootloader, Install custom recovery, make a backup of your current stock ROM, and then go to install a custom ROM.
NOTE: It is good idea to note your software version and your baseband version right now(enter *#1234# on dial pad)
This is so you can find your stock ROM on https://www.sammobile.com/ and flash with Odin tool.
Unlock bootloader
In our samsung phone it is very easy to unlock the bootloader. All you have to do is go to Developer options and enable OEM Unlock(something similar to the image below)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
To enable Developer options, you go in About phone, and press on the field Build Number multiple times(something similar to the image below)
Install custom recovery
There are multiple choices for custom recovery for our samsung phone. I recommend to install TWRP 3.3.0(link here https://github.com/ananjaser1211/android_device_samsung_jxy17lte/releases)
You need samsung USB drivers(link here https://developer.samsung.com/mobile/android-usb-driver.html and the
the Odin tool(for flashing the recovery)(link here https://odinflashtool.com/download/odin3-v3-13-1/
1. Turn your phone in to Download mode. For that, first power off your phone, and then hold POWER button together with volume DOWN and HOME button, then connect the phone with USB cable on the computer.
2. Open Odin tool
3. In the options tab, uncheck auto reboot
4. Select the custom recovery image in to AP field(the exact file name of recovery from link is TWRP-3.3.0-j7y17lte-20190417.tar
5. Start flashing.
6. Now, hold POWER, volume DOWN, volume UP and HOME button together until your screen on the phone goes back, then instantly hold POWER, Volume UP and HOME button together, so you boot in to the installed recovery.
7. You should see the installed recovery working.
Set up internal storage so the recovery works properly
Warning: This operation WILL DELETE EVERYTHING ON YOUR INTERNAL STORAGE. COPY YOUR FILES ELSEWHERE.
Use your installed recovery to wipe the internal storage, so it becomes available for usage.
Select the option Wipe, then Format data, and then confirm the operation.
No you should be able to use your recovery for other operations.
Make a backup of your current stock ROM
Use your installed recovery to make a backup of your current stock ROM.
Select the option Backup, and then select all partitions, then confirm the backup operation.
After this, don't forget to copy the backup in your computer. For that, you can plug your phone to PC while you are in recovery, and then you can just copy the backup. The backup is stored in the folder named TWRP.
Install a custom ROM
You can use your recovery to install a custom ROM.
The general steps for installing a custom ROM are:
1. Wipe the partitions Data, Dalvik/Cache, System
2. Download the ROM that is a zip file and store the zip file in phone(either internal memory or SD CARD)
3. Use the install option in recovery to install the ROM
4. Reboot the phone.
Install a custom TREBLE ROM
Treble ROMS are different than regular custom ROMS, because they need the phone to have an additional Vendor partition.
To create a Vendor partition, use your recovery to install the zip Exynos7870_CreateVendor_2.0.zip(download from here https://forum.xda-developers.com/galaxy-j7-2017/development/treble-project-treblue-j710x-t4098875) and reboot your phone in to recovery so the recovery detects the new vendor partition.
Then you need to flash a particular vendor(Either Project Treblue, or H-VENDOR).
After that, you can wipe the partitions(Data, Dalvik/Cache, System) and flash the custom TREBLE ROM.
I recommend to flash this custom TREBLE ROM: crDROID https://forum.xda-developers.com/galaxy-j7-2017/development/unofficial-crdroid-6-7-t4119505
To flash crDROID, first install the zip Exynos7870_CreateVendor_2.0.zip, reboot your phone in to recovery, and then flash crDROID(note that the vendor is included in crDROID).
Revert to stock ROM
You can use Odin tool to flash the stock rom. First find your stock rom on https://www.sammobile.com/, unpack the downloaded ROM, and then use Odin tool to flash all the files(BL,AP,CP, CSC)
To revert to stock ROM using your recovery, first install the zip Exynos7870_RevertVendor_2.0.zip(link here https://forum.xda-developers.com/galaxy-j7-2017/development/treble-project-treblue-j710x-t4098875), reboot your phone in to recovery so the recovery detects that the vendor partition is gone, and then restore your previously created backup.

This is not an error that will break your phone. TWRP will install the ROM successfuly, so don't worry about the error. Since there is a Vendor partition, it is natural that the phone won't have a preload partition, so TWRP won't be able to mount it.
Now how is the ROM working?

it works well! thank you! I tried installing GApps (ARM64, android 10, stock) and that just puts the phone into a bootloop, so I re-installed the rom. maybe you know what it happens?

I don't use GAPPS, so i don't know what would be the problem.
I suggest you install pico package instead of the stock package.
If still not working, then I suggest you install bitgapps.

Do not flash cdroid, flash a treble rom instead. It should have a extension of .img instead of .zip
After flashing Exynos7870_CreateVendor_2.0.zip，flash skyhawk recovery project.
https://forum.xda-developers.com/ga.../unofficial-skyhawk-recovery-project-t4107145, rebooting into skywawk recovery,you should flash H-Vendor.
https://forum.xda-developers.com/galaxy-j7-2017/development/treble-h-vendor-v1-0-t4116277
Without rebooting immediately flash gsi image.

Hello. Sorry for the long reply ahead. I have the same problem of wanting to use 64 bit apps in my J7 pro (SM-J30G/DS). It's my first time doing a custom rom as well and I followed all the instructions detailed here, but things did not go well for me.
The only step I missed is copying the backup to my laptop because for some reason my device is not letting it be copied. Nevertheless, I proceeded to install the custom rom since I was hoping to use the stock rom in sammobile.com instead as backup.
However, I keep getting both the error 7 and "failed to mount /preload (invalid argument)" when installing crdroid. I tried numerous ways to fix it but nothing happens. The following are what I have already tried:
- Install older versions of crdroid (all versions causes error 7)
- Remove assert in "updater-script" (tried it in 6.9 and 6.7 versions but still get error 7)
- Install latest versions of twrp (I cannot find the latest version of twrp for j7y17lte aside from what's here, so I went to other sites that offer twrp for J7 pro (2017). I found j7xelte and herolte but they don't work, so I used given twrp here again)
I can't fix the error and the install was always unsuccessful, so I decided to use another custom rom which is HavocOS. I followed the instructions but I still get the error 7 when installing project treblue. I tried removing assert again but the error is still there. I researched more but I can't find any more solutions to this problem or what's causing it.
One thing to note is that the create vendor zip was installed successfully (but with failed to mount/preload) and only the custom roms receive error 7. My research about error 7 said that it happens when the device is incompatible with the roms to be installed, but I'm pretty sure that my device is J730G/DS which should work fine since it worked with others here that have the same device. If my device was incompatible, then why does the twrp and create vendor work fine? Is it because my phone was not rooted? I saw that a lot of custom roms require root before installing, but it was not mentioned in the instructions so I did not root my phone.
Another problem is that I can't revert to my stock rom anymore. I found my stock rom in sammobile and proceeded to flash it using odin, but then my phone is stuck in samsung logo after rebooting. I tried leaving it for 8 hours to see if it will load but nothing happened. I can still access the recovery so I reinstalled twrp and would try to reinstall my stock rom.
Any help would be appreciated. Thank you!
EDIT: After reinstalling twrp, I tried flashing the create vendor and crdroid again and for some reason, the installation was now successful. But after rebooting to system, it was stuck in the crdroid logo. I then went to twrp again, formatted the data, then installed HavocOS and to my surprise, it was successful! There are no problems with boot and I am currently able to use the rom smoothly.
Problem is fixed since I am able to use 64 bit apps, but if you guys know what happened and what steps I did wrong, please tell me! I am still confused with what the problem is and I don't want to experience the same problem when I update my rom. Any help would be appreciated. Thank you very much!
I want to run 64 bit in J7 max G615F
does it work on nokia 2.3 which is binder64?
