[HTC One S] Sneakyghost:
Here is a PM i got today and since the nature of it is actually a public support request i put it here so others can benefit from it too. I do not really like giving private support in this extend as it is quite time consuming and ineffective for the community. It defeats the purpose of a Forum completely.

Unlock can be reverted to stock if you are S-OFF. I would recommend to go S-OFF anyway as it usually doesn't really affect any warranty stuff and can only be done until you decide to flash the new 401.9 OTA. After that not any more.

There is a guide by some dude called Scotty/something (not sure, look for some scotty in dev section, search for "revert to stock" or "reset unlock flag" or something like that). You can make it appear untampered, locked. BUT: the very very most warranty cases are not caused through unlocking/S-OFF and so it doesn't matter for it. The only thing not covered by warranty is a Brick and if you encounter that, it really doesn't matter either if you're locked or unlocked as its not covered anyway. Bricks are almost everytime caused by the user, so they will refuse to warranty it anyhow.

Depends. It can be very unstable and sh.it if you do it wrong and it can be rock solid. I have had both. Very important: make sure you use a good recovery. I recommend to start with a RUU. Then first thing: unlock. Then flash Philz Touch recovery (just dont bother with TWRP if you are concerned about issues) and then wipe the system very clean with it. After that, flash 2.1 ROM, then clean cache and dalvik, boot the phone, set it up (just basic setup is enough for starters), then let it settle some 5 minutes and then reboot into recovery and flash the 2.2. OTA file. Once that is booted up, make sure you delete the appdata from Venom Tweaks in /settings/Apps and also change from the default Sense5 Theme to a HTC Stock Theme and then back to the Sense5 theme if you wish. That way, you will get rid of faulty graphics, Lags and FC's.

Sometimes, a flash doesn't work right even with Philz Touch.

Start over again then, always start with the RUU.

If you decide NOT to do S-OFF, you will HAVE TO flash the Kernel with "fastboot flash boot boot.img" before booting the ROM!

To compensate for WiFi issues (if you get them at all, i never did!) choose Tecardo's Radio Installer V6 and flash the right radio (1.15 EU, includes already ADSP and WCNSS partitions) but usually without the Wifi fix. THAT you would only choose if updating Radio to 1.15 is not enough to fix wifi.

This FAQ is outdated and not maintained anymore. Some of the bugs you get are outlined in my answer above. They all are fixable. Most important thing if you have issues: your flash didn't go right! The ROM is ROCK SOLID if flashed right! Definetely!

You seem to be thinking that i can support you a lot in private and you have very special interests.

Let me just explain: typing this answer takes me about 20 minutes in which i actually wanted to flash the next HTC ONE test build from Torxx and report errors to him so he can soon release another build. I have soon to go to work again and so i am reluctant to spend my time supporting only one member. It benefits only one.

Sorry, i hope you understand.

The ROM can look mostly stock, yes, just tick or untick options however you like in the Aroma Installer.

I do not understand what you mean by Quicklinks in Taskbar. Do you mean Horizontal or Vertical Extended QuickSettings (EQS)? They can be disabled in Venom Tweaks app.

If you do not like all these options flash a stock ROM like they are offered A LOT from other devs or pick Torxx's Trickdroid.
