Rooting Nokia 8110 - Success with trial and errors

This page doesn't tell the detail of how to do Rooting, but this is the addendum to make it. 

Following is the lesson learned from trial & errors of rooting Nokia 8110, untold in the web site: https://sites.google.com/view/bananahackers/home?authuser=0
This site is the only & wonderful source of how to do Rooting, I just added more comments on something untold or unclear for me.

1. Safe Method using Firefox 52.9ESR was not working for me with Nokia 8110 ROM 14.0, Under Windows 10 - Cannot do "Open package App: OmniSD", but Under Ubuntu - Cannot do "Remote Runtime at port 6000". Both OS are the latest as of 2019-04-01. 

2. I recommend to use Alternative Way at Ubuntu (Windows doesn't support this ) : https://sites.google.com/view/bananahackers/install-omnisd/alternative-jailbreak?authuser=0, but you may suffer from one thing with an error : XPCShell : File Not Found. No solution for this with hours of googling, but some hint at this site : https://groups.google.com/forum/#!topic/mozilla.dev.b2g/kzzdiL1pzVc

Summing up, you have to download "xulrunner-18.0.2.en-US.linux-x86_64.sdk.tar.bz2" not "xulrunner-18.0.2.en-US.linux-i686.sdk.tar.bz2" though you're using 64bit of Ubuntu due to compatibility issue. FYI, I have VM of Ubuntu under Windows 10, and connect Nokia 8110 to this guest OS.

3. Though you choose the right xulrunner, you need to modify a Makefile in "make-kaios-install" directory, and here is how to : https://github.com/digitarald/make-fxos-install/issues/6 

You need to change the last line of Makefile like : (xxx is your home directory)

@env LD_LIBRARY_PATH=/home/xxx/firefoxOS/xulrunner-sdk/bin ${XPCSHELL} install.js ${ID} $(PORT_LOCAL)

There is no comment about heading "@", but you need to do it, otherwise you will face another error. This is to avoid of missing library to run XPCSHELL, otherwise you will see "File Not Found" error.

4. Do not in Debug mode of Nokia 8110 when installing OmniSD, otherwise you will be stuck at "Connecting..." message in your Ubuntu terminal. Rebooting is one of way to be out of Debug mode for me.

5. You need to install OmniSD again after success of installing it as explained.

6. There is no guide how to install custom apps after into developer mode : You need to copy those Apps into SDCard under "Apps" or "downloads" folder in .zip format intact. You can install those in OmniSD app installed at step 5. Or, you can copy those by using USB connection into internal memory.

7. SDCard should be formatted by FAT32 format (exFAT is not supported in Nokia 8110). You may need to use the 3rd party tool like : http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm

There is no comment on this on the manual, I cannot believe it.

8. Do not insert SDCard into slot 1 of USIM1 slot, you can see where to insert it at page 8 : https://www.nokia.com/phones/en_int/support/api/pdf/nokia-8110-4g-user-guide?locale=en

If you don't read through the manual carefully, you may make this mistake.

You can do rooting Nokia 8110 with these trial & errors successfully.

P.S: If you're not into Linux, you may need to know how to unzip tar.bz2 file :
