[LG V20 Themes, Apps, and Mods] Ice Fire:
Not 4, fairphone 5 it was released about two months ago. There are no guides for that, that perfectly apply to the V20 the filepath differe on every phone. With some phones you need the terminal to debloat with the V20 total commander is enough.

Lineage os supports 4G mobile data on the V20 so that is a mainboard or provider problem.

I know these cheap boards from ebay but they are either broken unrootable or have american frequencys. A new board would not help with the data stuck on the old board. I have my US996 and the F800. Consurning aliexpress i heard german adresses where possible at some point but peculiaritys in my name and adress make it impossible. I dont trust them beyond that. A new board isnt the issue to begin with. The V20 is to slow for my day to day stuff and thats why i got something new after 6 years.

You cant use generic guides as they will just tell you what you want to hear. I had my troubles belive me i am at a point where i can discount a websides by the first statements when it consurns the V20. They often toute some extreme nonsense.

You have to look exacly for the V20. Installing Lineage OS is actually an extra step in unlocking a stock rom the steps are virtually the same but you have to make sure that TWRP sticks with Magisk as a stock rom will reinstall the stock recovery if you dont. Meaning after twrp has been flashed with the command you turn the phone of by any means and root first. Also i have found that the latest versions of magisk softbrick the v20 leading to you having to start over which is one thing mentioned nowhere for example becaue the phone is so old. The last one that works is 22.1 that goes for the magisk version the app version can go higher but you wont have any benefit from that as the magisk version counts.

Talk about frustration i worked more than a year on and off on getting VoLTE to run.

The H990n would be soft converted into a H990DS consurning the Volte registration only. It will still remain a H990N for the rest of you software. It is paramount that you back up all the stuff i am talking about in my guide i am sure i mentioned that. At least the VoLTE registration files are accessible with the H990s or anything else that does not come from the us. But they just had to give the offical unlock to the us version. I can only activat it for tmobile there.

On how to get back to stock at first back up your stuff your phone will obviously be autowiped during that process. You need the a correctly set up lgup (man am i glad that i dont have to bother with this nonsense anymore). There are a lot of versions and ou have to find one the works when you plug your phone into your pc in download mode. Then you need to go to lg firmwares website and pick the one you want choose carfully as you can only do two downloads per day. For volte you need two possible three versions. One Oreo and the one Nougat version for the dirtysanta process. Pie and Nougat for the F800. You cant make a complete wipe after the unlock because the new android version dont have some settings in the engineering mode (when you enter +#546368#+990# in your dialer on stock) that will only be present if you upgraded from nougat befor if you directly install oreo they will be missing as oreo does not have them but wont overwrite them if they are still present from nougat.

I have all the knowlegde and eeverthing i did on or for android on a 1 tb harddrive which is already 75% full. I wrote down the more difficult to remember stuff on there but a root guide is to of topic for this subtopic and the overall topic with it behing themes apps and mods.
