O2 Firmware

Go to the rom section and have a read about flashing.

The process is quite simple and you can choose any rom you like.

You will need to:

1) Unlock your phone so it can connect to any network

2) Replace the onboard Boot loader (SPL)

(This allows you to copy a rom image onto the memory card, press a

couple of keys and reset the phone and it will flash itself)

3) Choose a ROM and copy it to the memory card and reflash.

The current O2 firmware contains Windows 6.1 but you can try 6.5 from the ROM section.

Google this and you will find the current O2 FW for the Stellar.

[XPERIA X1 ROM Development] qweqwe99:
Hey fellow beta testers and chefs... I decided to create this thread so all of us are aware of what ROM's can we actually use and not have to sniff for bugs (that's if your purpose is solely for testing). I know theres a ROM library stick thread but it's still not clear especially to the noobs as to which ROMs are completely bug free. So let me do the honours of posting the first ROM :

Touch X 10.1 ULTIMATE X-TREME "FINAL"

Feel free to add on the thread so we can have a list going please! And thanks for reading my post!
[XPERIA X1 ROM Development] JadeSimon:
UnOff v5 by Spikegotti - bug free, 100% original xperia on top of wm6.5, stable, fast and very battery efficient.
[XPERIA X1 ROM Development] qweqwe99:
Ok here's the issue I faced with the v5 UnOff and older ones. The Xperia dialer skin has to be disabled in order for the scrolling bug. But I really like that skin and it represents our X1's; without the skin it's nasty. Please correct if theres a fix without removing the skin. Thanks! So basically when I mean bug free..It has to be PERFECT!
[XPERIA X1 ROM Development] smaberg:
There won't be any one "perfect" :p you can always expect one or more bugs atleast, as this is windows we are talking about :D
[XPERIA X1 ROM Development] qweqwe99:
smabergg!! I consider your rom perfect...OK OK near perfect...lets use Touch X 10.1 as the basis of comparison... lol Alright completely forgot that this is windows mobile we're dealing with...so the purpose of this thread is to extremely narrow down the rom's and be as strict as we can with no room for a little more than minor bugs..so we can all peacfully flash our roms knowing that almost everything will work as expected..hope I'm making myself clear!

P.S. almost forgot..THANKS TO ALL THE CHEFS OUT THERE FOR COOKING THESE AMAZING ROMS, WITH FEATURES THAT AN X1 IS NOT EVEN SUPPOSED TO DISPLAY...THANKS FOR YOUR HARDWORK!
[XPERIA X1 ROM Development] drhussamm:
I am not a professional user. My little experience with good X1 roms is:

WM 6.1

1. nX1i v1.04 [SuperLiteSpeed]: exceptionally fast and stable ROM even after installation of your staff. Norti provided all needed programs in separate installation. For me, it is a perfect ROM.

2. Jack V3.x

3. touch X 10.1

WM 6.5:

I believe that Agent_47 provides the most stable and fast ROM. For me, the best releases are

V 2.3

FS 2.9

Experio 1.8.5: my favorite

UnOff roms, Christian's roms, and Energy roms are also good but I usually feel them less responsive after installation of my staff. Grab's Barebone rom is also good but I felt that it has some troubles with 3D applications.
[XPERIA X1 ROM Development] yingyotc:
I agree with you for WM 6.1.:)
[XPERIA X1 ROM Development] Sfkn2:
Ah, so it's normal that the phone lags up after you install programs onto the UnOff rom. I posted a question asking others if they had the same problem, but have yet to get a reply. Thanks.
[XPERIA X1 ROM Development] ulysse84:
one vote for JackV4. for daily use, it's really bug free and responsive.

Here it is... I don't recommend the newer ones yet, bugs still haven't been squashed.
[XPERIA X1 ROM Development] spikegotti:
everyone complains about bugs, but do you guys know that the builds which were leaked were not the final? the builds are still being worked on by microsoft so dont expect anything bug-free.

almost every rom wears a different build, meaning different bugs and speed,

and dont complain about the rom becoming slow after installing apps, every single operating system slows down after installing apps, even linux and apple os x...

if your storage drawer is filled with clothes, obviously it would take you longer to find a pair of socks than if it had just 3 items, the same thing applies to any computer device

if you install 32 apps and games to be exact like i do in total you should not have a slow device, but obviously it wont be as fast as when its like first use, mine is never slow and i been installing these since day one on 6.1

if you need anything bug-free, there is always wm 6.1, but as for now, wm6.5 is not yet completed, so expect bugs of some sort
[XPERIA X1 ROM Development] drhussamm:
I agree. But the response after apps installation is different. ROM like Norti 6.1 nX1i v1.04 [SuperLiteSpeed] shows excellent response after app installation while others show marked slowness. i think there is something different in memory management between different builds. The same happens with different 6.5 builds even if from the same Chef.

[XPERIA X1 ROM Development] Darkchaser:
I give my vote to Touch X. The latest versions are indeed buggy, but then again so are most ROMs. But at least Mr Rusch is very quick in providing fixes. For me Touch X is a great balance between speed and eye candy, especially with 10.8 with the Leo icons and animated weather wallpaper :)

EnergyROM is great

I tried Touch-It v14.2.1 but it was full with bugs, Then I switched to EnergyROM (The build from 09-22-2009) and it is great. It is very fast, very stable and very "polished"
[XPERIA X1 ROM Development] eDaniel:
spikegotti's is my favorite. Rock solid and fast as well. There is a slowdown in the scrolling in the start menu but it's expected because I have a huge collection of installed applications/games. The cure - use folders to group this mess.

Congrats spikegotti
[XPERIA X1 ROM Development] kitman:
for me the most stable and fast rom WCX http://www.wcxxperia-nce.com/index.php

all the roms release have their own unique experience, energy = speed and eye candy, agent47 = latest stuff & options, spikegotti = clean xperia 6.5 and many many more like touch-X, touch IT, jack, christian etc ........ thank you to all the chef for the customise rom.

my suggestion is to try all the different type of rom and see which one fit your need.
[XPERIA X1 ROM Development] amandeepphull:
Well, in first place by a mile (IN MY HUMBLE OPINION!) - PC TECH 4 U

1) PCTech4U - It has eye candy, stable,Loads of apps, and VERY FAST, even after you install all your crap! lol http://xdaforums.com/showthread.php?t=536551

2) Touch X 10.1 (By smaberg) - http://xdaforums.com/showthread.php?t=493848

3) Christian's Lite 2.903 (NOTE: LITE version) New Build, looks good, and the first of the new 6.5 builds that work well in terms of speed and stability - http://xdaforums.com/showthread.php?t=542664

4) x1owner's X1Ov1.2 LEO WM6.5.1 23060 MANILA2.5.1919.2828 R3A ENG (WWE) http://xdaforums.com/showthread.php?t=564298 REASON : VERY quick, looks good, TF3d is FAST and i mean faster than some 6.1 builds. Touch Flo 3d Doesent work in landscape, but it doesent crash, and titanium works fine in landscape.
[XPERIA X1 ROM Development] ani_fan:
Agreed

I've been following this thread and was surprised that PCTech4U wasn't mentioned until the last post so I'd definitely second that :D For me Winmo 6.1 is still the fastest and most stable and uses the least amount of ram even with TouchFlo running.

As for Winmo 6.5 Roms, I like the Energy Roms. Very few bugs after the prescribed fixes and good combination of eye candy, speed and smoothness for Winmo 6.5+Touchflo 2.5 or Leo.

Touch-IT v15...check it out
[XPERIA X1 ROM Development] harveydent:
Hi Myke! Is Touch-It 15 REALLY stable? Was using v14.2 and it kept hard resetting spontaneously...
[XPERIA X1 ROM Development] x1owner:
thanks for supporting my rom. i use it since i released it and it works stable and really fast. only landscape is not working in htcsense since it's not yet developed by htc. give this rom a chance.. you won't regret it....

enjoy all the nice roms here at xda-devs.
[XPERIA X1 ROM Development] Jezza0:
I have to agree that PCTech4U v2.0 is one of the greatest (and perhaps least recognised) ROMs for the Xperia. The fact that it has not been updated for 3 months testifies to its stability.

The only reason I don't use it regularly is because it has cooked in a few things I don't want, like S2U2 and fingerkeyboard. That, and I'm a flashing addict :p
[XPERIA X1 ROM Development] jlhc87:
I'd like to know whether anyone has used Jack 4.x for WM6.5 and actually found another rom to be more stable than that?

[XPERIA X1 ROM Development] plymman:
this might be a stupid question but how much does the choice of rom affect battery life? what rom gives good battery life as well as stability?
[XPERIA X1 ROM Development] steryd:
Touch X 10.1 was really good, but then Touch X 10.5 was an absolute failure - lots of bugs, much worse than its predecessor. So I decided to give another try to a WM 6.5 ROM.

I chose EnergyROM (built 22/09/2009).

And it is superb. As fast as Touch X 10.1, but much more decent. WM 6.5

is finger friendly and new HTC interface with beautiful color icons is simply perfect. There are no issues with this ROM. Best one.
[XPERIA X1 ROM Development] whitemdx03:
I am also using NRG's EnergyROM 'Photon' Ed (Manila 2.1, built 9/22/09) for the past week, frozen 1, haven't encounter any other bugs from daily use. I don't like Manila 2.5(LEO) b/c it doesn't have the program tab:(, I use it all the time.
[XPERIA X1 ROM Development] amandeepphull:
I Can't agree more! PCTech4U is defo the best overall ROM i've used. I disabled Slide 2 Unlock 2, and the only complaint i used to have was fingerboard

BUT i realised that fingerboard is actually faster if you just have to punch in a word or two (a few seconds saved), because the screen does not have to re-render to landscape making faster to type words where i'd use the keyboard and we all know sliding the keyboard out n the screen rendering itself slows it down sometimes.

THe only change i wanted to x1owner's ROM is the xperia panel, because i like to use the CNN panel while im on the toilet haha.

(and flashing is an addiction!! I;ve been pretty blown away by X1owner's rom because most 6.5's with a load of stuff crash and also Christians 2.903 LITE.)
[XPERIA X1 ROM Development] guibao:
I've been using Smarberg's rom for a few months since I bought my x1 and today I decided I wanted to give a try on winmo6.5.

Most of the ROMs suggested here dont handle landscape mode so well like Smaberg's did.

I tested 3 of them and they failed on many parts, Home screen, dialer, sms, etc.

Am I missing something?
[XPERIA X1 ROM Development] MykeChester:
yes...stable enough...official winmo 6.5 + manila 2.1 (1919)...hometab weather is animated, similar to leo;)

and watch out for itje's new "clean ROM"...test ROM already available
[XPERIA X1 ROM Development] vietdoan20062006:
at the moment im using offical 6.1 rom after months of flashing many roms here

- Touch IT Xperience

actully i dont like firestorm rom

[XPERIA X1 ROM Development] Draqula:
I'm glad someone started this thread!

One doesn't have time to test all the ROM's by itself so it's great to have feedback from other people who are also looking for stability.

X1 is a senior, we have had fun experimenting but before cooks move on to newer devices it would be nice to have them put all the experience they gathered into some bug-free, fast, stable and battery-efficient ROMs!

Xperia 6.5 UnOff by SpikeGotti. Haven't got any problem with it. Did have a slowdown when I installed it but is now back to being zippy after a soft reset :D
[XPERIA X1 ROM Development] M.Ozturk:
Is there an integrated version of the official window 6.5 for Xperia available?
[XPERIA X1 ROM Development] vsinha71:
have been using unoff rom for the last 8-10 days and would like to say that it is the most stable and smooth "xperia" rom among all that i have used. there has been abso no issues with speed, apps installation et all. Memory is good at 250mb storage and 145mb program memory- the highest(program memory) among all other roms used till date. combined with the option of uninstalling the media panel alongwith suduko, bejewelled and radio panel (i use power and resco radio) the storage memory goes upto 280 mb which is really cool.

having 145 mb as program memory is really cool and fast. the rom is pure xperia which i am really hooked and is fantastic for day to day use.
[XPERIA X1 ROM Development] qweqwe99:
Alright about this UnOff Rom, how did you guys solve the dialer skin problem without disabling the skin?
[XPERIA X1 ROM Development] THE GRIZZ:
PCTech4U for me.

its a bit outdated and has many things that i dont use but still the best for me

i hate all leo roms they all have this "proof of concept" feel into them
[XPERIA X1 ROM Development] jackleung:
Well, some people just happy to see a big number on free memory and don't realize having lots of free memory is simply a waste.

I remember I could make a lite rom w/ 150+ mb free but I rather use the ram wisely for ramdisk and caching to speed things up.
[XPERIA X1 ROM Development] xanadu:
You're right, 80-100 MB free ram is enought with balanced ramdisk, paging pool and cache. Tried all available english and german roms but your v3.11 is the best for me till now on my SEX1.
[XPERIA X1 ROM Development] ulysse84:
Totally agreed. But only one point: where is your next? :D
[XPERIA X1 ROM Development] spikegotti:
hopefully there will be a more recent build of wm 6.5 that can solve this issue, or someone with the x2 prototype can share the dump with us

about solving it without disabling it, you can use a 3rd party dialer/contact management app (which most windows mobile users does), the default one sucks anyway

thanks for those who tried n use the UnOff rom

personally i think this thread is useless: you try the roms you see, what you feel comfy with, you stick with it, simple... obviously everyone will state the ones they are using, even if they haven't tried another
[XPERIA X1 ROM Development] VNMenIeu:
Jack's 3.11 rom has the best battery life so far.
[XPERIA X1 ROM Development] bigbelly72:
I was rapidly flashing most of the major ROMs until I tried Jack's 3.11 Medium.

So far it has been rock solid stable, and the video performance and web browsing are very fast (tweaked Opera). I stayed with it for about 1 week, tried a bunch of other ROMs again because of the hyperbole in the threads, now I'm back to Jack's again.

Stable, fast, and perfect for my real world use.
[XPERIA X1 ROM Development] xxdeesastr:
I wanna know if it's possible to translate the best 6.5 rom for Xperia, it should be possible for a cooker. I don't have see a lot of french rom for windows 6.5, the Xperom is the only real alternative for the moment

Do you know an other rom in french?

Thanks to all the people :D

WM 6.5 Leo:

Didnt have lucky with energy. I got several bugs (sms, settings, music, etc etc) and my phone got hot with it... (dont know why i loose my hsdpa with it, maybe a config that a noob like me dont know yet)

Tried Firestorm 3.9 and it is running flawlessly. A little slow compared to wm 6.1 but i cant find any errors. Ah and its battery consuming ;P.
[XPERIA X1 ROM Development] VNMenIeu:
Yeah, but there are couple annoying bugs on Jack's 3.11 medium rom like the menu graphic on certain programs mess up and the active sync. I'm using Mr. Rusch 10.8 Ultimate. I think it's the best, very stable and not very buggy.
[XPERIA X1 ROM Development] xicloe:
From first time my X1 in my hand just 2 days with the official WM.6.1 RA1xxxxx, then until now I used Touch X 10.1 perfect it's been 3,5 month. :)

Maybe this time to flash again :p touch X 10.8 ??? energy ??? touch IT ??? don't know, just patient waiting something perfect again :D
[XPERIA X1 ROM Development] emarek:
I tested a lot of ROMs. The best result I had was PCTech4U v2.0 WWE - still my favorite. :D
[XPERIA X1 ROM Development] sambir:
with Mr. Rusch 10.8 Ultimate my phone was unreachable. When i called my number it was always busy like it was calling someone. I replaced it with 10.1 and the problem was solved :S
[XPERIA X1 ROM Development] xanadu:
With 10.8 Ultimate on my SEX1 alarm was only popup message, no sound. 10.5, 10.6 and 10.7 was better.
[XPERIA X1 ROM Development] blacklion33:
Well, not quite useless ...... not everyone is a flash-freak and has the patience to flash every single piece of rom on the forum. :)

I flash almost 3 roms per week and right now i'm following these 2: NRGZ28's standard (few bugs in the last rom doe) and Mr Rusch 10.8 (stable and fast and no bugs so far).

So, after all i think this thread will help new ppl, new to Xperia i mean.

Tested the nww Firestorm 4.0. Runs perfect on my X1a.

Allmost anything working. No bugs, no slowdown...
[XPERIA X1 ROM Development] spikegotti:
this is why i said what i said

everyone is not, that's true, but im sure before a person flash, they read to find out what they need first, example: if you want manilla, you would search or the manilla roms and check the threads...clean:same thing

no one just see a rom download it and flash it, every person read some kinda info on the related thread about the rom first, bugs, speed and so on; the entire or some feedback rather than a thread about peoples opinions

few weeks ago if this was asked i would have answered christian's clean rom, but that's bias, bcos i only tried 3 roms here on xda, how can i answer about the others? its a 1st user experience thing, not hearsay, we have SE fanboys, and we have flashaholic fanboys :D

but a thread like this is very bias...its like polls, polls are useless unless you ask every single person who is related to the poll...this is why i only follow election poll ballots :p

you will never get an accurate answer by asking over 10,000 people, when only 61 answered...what if more than half are lefties? or even all?
[XPERIA X1 ROM Development] CommanderThor:
Ah the best is to first find the cooker you like(meaning he includes things you want in ROM) So you dont have to install to much and mess things up. Than you go and in stall his versions right after they come out. Eventualy one version will be bugfree. For example i install agent's ROM's and 2.9 was the first ROM i used for 2 months, 100% bugfree. even instaled it for i friend, taht has no clue how to use Xperia at all:)

But than i am flashoholic and wanted to try new roms:) Noone from 3.x branch waas 100% perfect for me. Maybe one from 4.x will again be the replacement for 2.9.

I just love the new build with startbutton on bottom.
[XPERIA X1 ROM Development] Osama Shah:
Mr.Rusch's 10.8.1 feels good, seems 99% perfect... the 1% bugs don't hinder day to day use.

like someone here said, not one ROM would be perfect, after all we have to realize they are using a Microsoft base!
[XPERIA X1 ROM Development] guibao:
Well the thing is

I spent the last 2 weeks testing the top 3 winmo6.5 roms I found on many suggestion threads. Then I tested the top 3 winmo6.1 roms, following the most recomendations I found.

WinMo6.5 wont go landscape but in one or two tabs.

Some 6.1 ate a lot of battery, one went crazy with bluetooth, anoter didnt load the browser.

Guess what?

Back to Smaberg's!
[XPERIA X1 ROM Development] demster:
I am a big fan of Touch IT Xperience by Itje. Though not always as stable and fast, there are a few version that are. The 15.1 beta is incredibly fast and I have not encountered any bugs so far. You will be really surprised how fast Manilla responds!

[somewhat offtopic]

There is a thing I am wondering about though:

-why would you want a version in your own language if there is an English version? I have seen French, German, Danish and Swedish people asking for roms in their own language, but what is that good for if you understand English? I know not everyone understands English evenly, but it is a good way to get to know it. I am Dutch and I want everything in English (Windows 7, Windows Mobile), because most of the manuals and programs are in English and the first updates are most likely to arrive in English first. Again, I am aware that there a are lot of people that don't understand English that good, but I'd like to know why lots of people want to have roms in their own language instead of English :)

[/somewhat offtopic]
[XPERIA X1 ROM Development] tictac0566:
Well, most probably like many other people here at XDA, I originally bought an X1 because it was a promising device. After just a short while of using it, I was not really happy.

Threads like this led me to the ROM´s I have flashed - and I am thankful to both the chiefs and the users contributing - myself, I am not really a frequent poster here. Shame on me. However, I think it is also a good idea to make a donation from time to time to keep things running.

I have flashed maybe a rough 50 times so far. From my own experience, it seems that hard resetting is utmost important to avoid many, many effects which sometimes seem to be a bug.

Also, the selection of the radio version can be important - especially when battery usage is kind of unexpectedly high.

In the sum, I was stuck with the 10.1 Touch_X ROM for a long time, then I went on to NRG´s ones up to the 09022 standard version, only to go back to Touch_X 10.x.x from Mr. Rusch - which offers exactly what I want and need, including stability, performance, and some eye candy.

The best "basis" IMHO is to go for a "clean" ROM which is offering useful applications, and which can be "extended" with additional cabs if you like more eye candy.

Anyway, thanks to everyone who is contributing - if this forum would not exist, my X1 most probably would not be mine anymore since quite some time!
[XPERIA X1 ROM Development] vpmohammed:
