[HTC Excalibur] joeskull:
First of all, let me say that so far, there is no Portuguese-Brazilian version of Wm6.1 for the HTC S-621 and maybe this will never exist at all…

If you are new to ROM Upgrading, you MUST read this! - PDF file - 2,5 mb + - (pages 1 to 11 only - keyboard issues are treated here)

That said, let´s cover the main issues you may have (at least the ones I faced) when upgrading to 6.1 for brazilian people.

Before we get started, let me tell you that I´ve tried all 4 flavors of roms available (so far) in this forum (in chronological order, i guess):

1 - Kavana

2 - Kavana remade by Rickwatt

3 - NGR Rose Rom

4 - NGR Rose Rom remade by Ricky and Stylez

And the best one that fits in my S621 (when you talk about funcionality and the little amount of trouble) is the second one (Kavana remade by Rickywatt) in this thread:

CLICK HERE to get Kavana remade by Rickywatt

With all other ROM´s i had some irritating issues, like CAP key nonresponding, comm manager not opening when you click on it, dialing “0” (zero) and getting TAB instead, typing “£” sign instead of “ç” and so on….

The very first change you MUST do is changing emergency number (911 does not work in Brazil – 190 does). All other changes but this one can be postponed, once you are dealing with life!

In order to do that:

Goto START – ALL PROGRAMS – MYTOOLS – REGISTRY EDITOR

Find these Regkeys:

HLM/Security/ECall

Scroll Down to LIST, press Center Button and change the “911” number to “190” (wich is the emergency call here in Brazil) – Confirm Change.

Find

HLM/Security/EcallWithoutSIM

Scroll Down to LIST, press Center Button and add “190” number. Press Done, Confirm change and repeat steps with:

HLM/Security/ECallWithSIM

Add “190” to it the same way.

DO NOT softreset the device yet (it´s necessary for changes to take effect)... there are other changes to do before softreset (Just to not waste time resetting it several times).

Needless to say that by doing this, you´re setting your phone to dial 190 (the emergency number here in Brazil – Remember, this guide is for brazilian people) even if keypad is locked.

______________________________________________________

Now let´s change some regional settings to best fit our needs here in Brazil.

Goto START – SETTINGS – CLOCK AND ALARM – DATE AND TIME.

Change TIME ZONE from London,Dublin (mine is at it – Who Knows why?) to GMT -3 Brasilia. At this point, you are able to change clock top to 24 hour format (I prefer) by changing values on CLOCK ON TOPBAR item (this step is optional)

Yet in settings, goto REGIONAL SETTINGS and change LOCALE to PORTUGUESE-BRAZIL. Press Done then OK.

Remember DO NOT soft reset yet.

Click done twice.

Is it done? Cool... now let´s do the trick: Goto START – ALL PROGRAMS – TEXT NOTES and click NEW to create a new one. DO NOT TYPE ANYTHING YET! Press FN + SPACE Keys to bring the language menu. Navigate to LANGUAGE (3) Choose PORTUGUESE (8). At this point, try typing a single letter, like the “a” character. You´ll notice that the XT9 dictionary will suggest you to use “a à á â ã” (for those out of Brazil, we use this special symbols very often). This is the predictive text working as it should be in all other ROM´s, but unfortunately, things are not as it were supposed to be.

Let´s go on...

Try pressing FN key and type the “J” letter... You´ll get an £ (Libra) sign instead. Type FN key again and type the “K” letter…. You´ll get an $ (Dollar) sign. It´s wrong… at least in my keypad, if you press “J”, “K” or “L” with FN, you should get the “ç”, “º” and “ª” signs.

Nevermind… let´s fix this…

Done with your annoying “ HEY! this is not the key i wanted to show up” thing? Ok. Now you can discard the note (press MENU button and choose CANCEL).

Remember the “eT9.Excalibur.0409.kmap.txt” file attached here? Did you got it? Put it in your mobile´s Windows folder, replacing the existing one. Your keyboard is fixed now, but do not test it yet, because it needs a reboot to apply changes.

________________________________________________________

NOW is the time for the first soft reset. Press IE key (this will bring Celetask) goto MENU – UTILITIES – REBOOT – confirm and wait.

Get back to text notes (START – ALL PROGRAMS – TEXT NOTES and click NEW to create a new one), and try typing something, like “jo”. You´ll notice that the XT9 Dictionary is giving you some options, like “jô jogo José jogos jogadores jornal”. It means the dictionary is working properly, as it should be in all other roms, but unfortunately, it only works in Kavana´s remade by Rickwatt. God knows why!

Now, try to type any vowel (a e i o u). Let´s take “e” for example. The XT9 give you some options like: “e é ê”. You see? Again, it´s the predictive text working as it SHOULD be in ALL other ROM´S...

Let´s try one last word... type “versao". It Will give you the option to use “versao versão”. (Just for your knowledge us-citizens, versão means version).

Ok? Done? Are we even? Now, let´s make it more confortable to use...

Some will say: “Hey, there is a Free RAM utility already built into the ROM!” or “Hey, there is CELETASK that does this trick!”.

Ok... I agree... I totally agree and I surrender. Use it! You done? Now, go to main screen and try to go to Comm Manager... close it using celetask. Try to open it again…Could you? Me neither. It´s a very common and strange bug among alternative ROM´s.

Oxios memory does the trick without this issue!

Whenever you want to free up some RAM (and speeding up your smartphone as a consequence) use Oxios Memory (the icon is a skull with a black hat and a red stripe on top of the hat). It´s completely harmless and best of all – free and works!

That´s it… Rom developers, I hope you see this topic and try to help us here in Brazil by including at least the keyboard layout and the predictive text in your future rom´s.

I´m waiting for comments, thanks! I also hope to help other people in trouble, like I once was.
