Does anyone have a working link to the virtual repartition twrp?

Seconded. Also, what about a recommendation for a GApps package? I keep getting not enough space errors and the seven I've tried so far, even Open GApps at pico is still too large.

You need to flash the lanchon repartition zip. I posted the full steps I used a few posts back. I used open GAPPs nano and it worked fine for me.

Help Please. I have been trying to flash this ROM but after rooting the step to resize the partition seems to have me stuck. I used PC ODIN to flash a PIT file but then when I boot into recovery I get the following error: E:failed to mount /system (invalid argument). I can wipe cache and data/factory reset but when I tried to load the Lineage.ZIP file I get the same /system error. I tried another pit file but it was exactly the same. ODIN says the pit file was completed successfully. Any advice welcome, any new pit files that I can use? Thank you. I then tried the lanchon repartition zip. but same error cannot mount system.

One step forward and one step backwards. I found a tar file for the i777 and flashed that at the same time as the pit file. Now the phone will boot and it does have the new larger storage. However the tar file was the original Android 2.3. I rooted the phone again and went into recovery but when you select the external SD card it shows an empty folder and so the 7..1.2 Rom that is ZIP'd on there I cannot flash. I need to do some more reading how to move forward from there. Any quick hints welcome, at least I've got rooting and resizing completed.

I am still stuck. Does anyone have a link to a valid i777 tar file? The stock recovery won't see any files on the SD card. I tried internal storage but then it says there is an error checking the ZIP. I tried a few alternative ZIP files so I think the recovery is the issue. I can still get to ODIN so if I could find a more up to date tar file I can flash that way. ANYONE?

I went through multiple times trial and error. I still not sure the right order but finally got it to work

1. Use Odin 3.07 PDA slot
CWM-KitKatCompatible-i777 v6.0.4.5
USB connected +/- power for Download
USB disconnected +/- power for Recovery

2. Flash SGH-i777_TWRP_v2.8.7.0
3. ‎latest Omni install boot reboot recovery
omni-5.1.1.20150711-i777-HOMEMADE.zip
4. ‎install virtual repartition
5. lineage-14.1-20171008-UNOFFICIAL-u1att
6. reboot into recovery TWRP 3.1.1.0
7. Load recovery image and do the data format and partition wipes
8.. SD card no longer works so load files thru MTP
9. Boot lineage-14.1-20171008-UNOFFICIAL-u1att
let it boot and config before gapps

gapps mini fits but nano is good enough

disable animations
force gpu

Thank you for the guidance. I have made some progress but cannot get this working. I have spent time googling and trying solutions but if you have any ideas I would appreciate it, my goal is to get Android 7 installed and WIFI working. My stretch goal is to getting it working with phone calls.

I used Framaroot 1.9.3 APK to root the phone.
I used ODIN 3.12.3 to load the i777_4GB data - 45mb preload - 1GB system.pit
I used ODIN to load CWM recovery which allowed me to load TWRP 2.8 (I cannot find TWRP I777 3.1.1.0)
Using this I can then wipe and load lineage-14.1-20171008-UNOFFICIAL-u1att.zip (I have also tried cm-13.0-20160927-UNOFFICIAL-u1att.zip and GalaxyS2Root.com_SGH-I777_UCLE5.zip)
I then wipe Cache, Davik etc and reboot
It hangs on the ROM logo and just stays there. (Ie gets past recovery)

Then I tried avatar-3.0-arion-1344-20130629-i777.zip which loads fine. I can load GAPPS for this and the phone appeared to work until I tried to load a SIM. Then I find there is no IMEI number in the system (IT is still physically printed on the phone). So with this Android 4 software and WIFI the phone seems to work fine.

Trying to get to Android 7 I reinstalled TWRP 2.8 and it says cannot mount /efs (In Avatar I can install root file manager and browse /efs so it only seems TWRP has this issue. )

I have tried GS2_repair apk but didn't resolve. I tried Chamelephon but it doesn't work on GS2.

The only other suggestion I read was to reinstall the stock android and that may recover EFS but I cannot find a stock I777 Android to download.

Thanks
PS Found a the EFS Professional Tool. This can repair NV Data File Permissions:
Checking device connection... Device is connected!
Detected EFS partition location: /dev/block/mmcblk0p1
Re-mounting ROOT file system... Okay.
Mounting EFS folder as read/write... Okay.
Repairing ownership of 'efs/nv_data.bin'... Okay.
Operation successful!
In the EFS folder I can see many files from 2014. Eg .nv_core.back; .nv_state; nv_data.bin etc but when I check in settings IMEI is still blank.

I think you are close. After you get to TWRP installed follow post #2 instructions

I want to install the ROM on my i777. But there seems to have been too many changes in the installation process since the beginning, ex. . Virtual repartition recovery TWRP and the Lanchon virtual recovery cannot be found. Would some one be kind enough to post the final step by step process in one post?

TIA

This project is EOL.

And also, I don't development SGS2 family anymore.

So, I can't support your problems.

Sorry.

Thanks OnyxClover.

Perhaps someone else who has already installed the ROM may be able to help PLEASE?
