Need help/suggestions on how to flash ArchiDroid on an untouched/stock XperiaM

Hi guys, been following this awesome community for a while now. I got a OnePlus One and I managed to unlock/root it thx to a thread on this forums (even if I'm not that "pro" with phones), but now I have my father's Xperia M (which has never been unlocked/rooted/flashed or anything) that is updated to Android 4.3 and I need help on how to proper install a custom ROM on it (I'm interested in the ArchiDroid one in particular). I don't like Sony's stock ROM, it's acting badly on some things (video recording for example) and in general it just sucks imho, so I want to upgrade to a custom Lollipop one (ArchiDroid). Can someone kindly explain me all the initial steps I have to take to, at least, install a custom recovery on the phone (possibly the TWRP since I used it for the OPO aswell)? Do i need to unlock the bootloader or something? Thx a lot!
Yes, u need to unlock your bootloader.U can do it through fastboot mode.Detailed information is available on Official Sony's Developer world page. Then flash custom recovery like cwm or twrp.Finally download the zip file and start flashing it.
Yep I managed to do all the stuff just yesterday, but thx anyway! Although it was not easy AT ALL, took me all day and was just a nightmare lol. The phone went immediately in bootloop after unlocking the bootloader, so I had to flash an appropriate firmware with flashtool, and I even had a problem at the very end of the process while trying to install the ROM itself (I choosed the official stock CM 12.1 nightly btw), because CWM was giving a stupid error. Thank god a guy here on the forums reported that CWM has problems with some SDs and posted a method to solve them all (by doing a total format of the SD with a program called SDFormatter).

yes, cwm recovery for now is not good for daily use. because they still have old commit. i suggest you to change to TWRP recovery, try look at here http://forum.xda-developers.com/showpost.php?p=61626285&postcount=1 we've got official support for this recovery:laugh:

Flash Stock Kitkat RUU on htc820u (Unsolved)

Hello everyone,
i bought an htc 820u recently and in the settings > about, software update is missing. Therefore i cannot upgrade to lollipop, that is my main problem.
I think that the only solution would be to install another stock kitkat rom so i can do the software update. i am used to flash samsung roms but when it comes to htc i know nothing. it's been 4 days i've been searching desperately but i cant get any tutorial to flash a kitkat rom. i managed to get a solution where it says to restore the kitkat rom through a twrp backup. i told to myself ok, i made a search on how to get twrp recovery and to my disapointment i find out that i need to unlock bootloader.
Once more i told to myself ok and go forward trying to unlock bootloader but i can't figure out how to do that correctly. All that struggle only to get a lollipop update, i'm really tired of that i'm losing all my time with this. If anyone can help me that would be appreciated. Feels really discouraging to look for something that much and not getting any results wow...
I managed to do it on my own finally after so much time. Thanks to ale those who saw the post and decided NOT to help. Topic closed.

Have you unlocked your bootloader ?
No not too sure how to do that. Any good threads you guys reccomend.
Many thanks
So I know this is scary for you and because it is something new, therefore be sure that you want to live with the responsability if something goes wrong.
Now, the next forum thread tells you how to flash an already rooted image BUT, and this is very important, this works only if you have the version 10c installed (Check in About Phone>Software Version)
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
If you have the latest version of the software (20a) the best thing is to unlock your bootloader, void your warranty in the process, and flash a custom recovery. After that, you just need to flash the SuperSu zip file and you will have root.
To flash custom ROMs, just access recovery and flash the zip file of your ROM.
I'm using the unofficial CM13.0 and works very good for me, but I do miss the official camera app.
Thankyou very much for your advice okarr. Will look into this

Can anybody quickly check my specs before I mess the tab up? :P thanks!

So..
My note's battery is pretty bad now, if I use a drawing software it will sometimes go from like 50% to 15% in minutes and then immediately after to 5%. I am almost 100% sure it is due a battery replacement but, since I always wanted to try rooting it I thought to do this as well anyway and see if it gets better.
(I've rooted my galaxy s4 a few times in the past but it was really long ago, so I somewhat understand what needs to be done but just need confirmation lol).
I plan to insteall Lineage OS 14.1 on it.
Question: it says that to do so you need to have a lollipop bootloader. Then it says "If the last Samsung ROM you had was 5.1 Touchwiz, you already have lollipop bootloader and don't need to follow these steps.".
I am on 5.1.1 as this never received any further update. On Droid Info it says: Bootloader P600UEUDQF1. OS version Lollipop MR1 (5.1.1).
So, I don't need to follow that step, right? I know, it's the dumbest question ever but I am not sure about it still.
Secondly... someone just please kindly confirm these are the correct steps:
1- (if needed) do the bootloader thing
2- install twrp. On the guide it says it must be ShevT's from here:
As far as I understood from the guide, rom already has root so I don't need that
3- factory reset from twrp
4- flash rom from twrp
5- flash gapps from twrp
Done?
Am I missing something?
Thank you a lot for taking time to confirm this

RM5G Android 11 7.60 to Custom Rom

Greetings everybody!
I recently got an android update to 7.60, which made the phone less worse, but didn´t cut all of the problems i had. After some new installations, I got sick of this firmware and decided to unlock the bootloader and switch to a custom rom. Unfortunately I am not able to unlock the bootloader with the instructions and got to the conclusion, that I have to downgrade android (don´t I?).
I am not very experienced in unlocking, rooting and so on, so I would love to have a full guide on how to get from android 11 7.60 to, what I believe is my best choice, Ressurection Remix.
I know there are many treats about this, but it seems not consequent and straight forward how different people get through this process.
Some links for the relevant files would be nice, especially for the unbrick tool, that I have to use and the rom, I have to downgrade to.
Thank you very much for your help and keep healthy
