Hi,
New to this site but glad I found it, what a handy resource!
I recently purchased a 2nd user O2 XDA II (about 12 months old) which is current setup in its factory default state. I have been reading allot about users upgrading their Himalya models to Windows Mobile 2003 Second Edition and I wanted to know if the same is possible for the UK O2 XDA II's?
Also will this upgrade lock the Phone and/or reduce the functionality of the phone?
What pre-upgrade tasks do I need to perform first e.g apply updates first etc.
Thanks in advance,
Taz
Watch this site carefully to find out about the SE version - there has been a breakthrough in the last few hours in which mamaich has translated the only official SE ROM (a Chinese one) into English. Work continues...
No Himalaya has been sold with an official English WM2003SE ROM as far as we know, but it may be only time....
What is the existing ROM version of your machine? The latest O2 UK ROM version is 1.72 which you can download from http://www.my-xda.com/xda2_soft.html . It's probably worth upgrading to that if your machine is a year old and is still on its original 1.12 (?) ROM.
Upgrading ROM doesn't re-lock an unlocked phone.
Before upgrading the ROM, backup all important data - it'll be lost in the update.
upgrade
THERE ARE A COUPLE OF WIN03 UPGRADES ON SITE AT THE MO BUT STILL IN THE TESTING STAGE.
I HAVE USED BOTH BUT THEY ARE NOT, JUST THERE YET.
AT THE MOMENT I'M BACK ON 1.72 WAITING TO SEE DEVELOEMENTS.
NOT SURE YET IF ITS WORTH THE BOTHER TO GHANGE AS THE DIFFERENCE BETWEEN THE TWO PROGS APART FROM VISUAL IS KINDA MINIMAL TO USE NON TECHIES, AND THERE IS A SOFTWARE PROBLEM IN THE SENSE THAT SOME PROGS DON'T WORK ON SE THAT DO ON 1.72 AND VISA VERSA SO I'M TOLD. ALTOUGH IF YOU DON'T HAVE ANY SOFTWARE LOADED THEN NOT A REAL PROBLEM.
BUT HEY WHAT A GREAT SITE, I'M LEARNING NEW STUFF DAILY, SOON I MAY BE A TECHY TOO!

Ha ha, cheers guys.
Yeah I came across the WM2003SE stuff by accident, was searching the net for some completely unrelated info and came across a link that caught my eye - would you believe it we have not one but two versions to choose from.
I am not too sure if I want to upgrade just yet, one of the reasons I bought a PDA in the first place was to start coding my own apps and as part of a large scale enterprise application I have been developing for over a year now.
If compatibility is an issue then I will hold off for now, I know Microsoft are slowly releasing WM2003SE related development stuff so I don't think it will be long before I take the plunge as I don't mind hacking my PDA's to peices.
As a credit to this site, I was searching various Pocket PC sites on the net (most are to bloated with info or just a bit too American for me) and came across XDA-Developers.com. It was because of the all of the info available on this site that I purchased my XDA II
I have already hacked it apart, I am running the latest 1.72 ROM and 1.17 Radio (is it worth ugrading to 1.18) as well as finally getting Pocket Hack Master to run the thing at 600Mhz with a 200Mhz bus (I will post the correct settings once I have verified that they are indeed the most stable ones).
Thanks again and good luck with WM2003SE!

Hi Gurus
Is it safer to apply HardSPL first then SIM unlock or the other way round.
Maybe it doesnt matter.
Whats your view ?
Asif
I did sim unlock first. then I apply hardspl. now flashing different roms. don't know exactly how the process suppose to be but that's what I did and my phone is working like a champ
I did hard spl, then Sim unlocked, not sure if it matters. I had the same query when I unlocked, but wondered if I missed something in the WIKI, so didn't ask due to a good flaming (if you aint done your research you can get crusified in here). Your braver than me lol
@AsifM3100: U need to do the CID/SIM update first; it will load it's own spl and radio. When U have completed the process, then U should install the hardspl before flashing your own radio and or rom.
Sotian
You post made me laugh. However I have made the same observation but couldnt find the answer in the wiki or other posts. Its one of the reasons why I have put off unlocking and flashing for such a long time. So many people who you feel sorry for, cos they have bricked their phones and who are panicking, just get told to do the research. When you are in that state the last thing you need is research. Its such a contrast to the SAP developer network site that I use regularly where evryone is so keen to help (me included).
Having said that its still the best site for us Hermese peeps. I would be in no state to unlock if it wasnt for this site. I just hope nothing goes wrong.

3 thoughts on this:
1. It is scary when the Germans are nicer than us
2. You gotta feel sorry for anyone hanging around in an SAP developer network
3. We aren't so bad when people have done research. It is the "HELP PLZ!!!!! - JUST GOT MY HERMES THIS MORNING AND BRICKED IT!!!!" posts that get people upset. Or the "CAN SOMEONE TELL ME IF THERE IS A WM6 ROM AVAILABLE FOR THE 8525 BY CINGULAR????" People who do their research and ask don't get crucified too badly - usually.
Oh, and regarding the question - doesn't really matter, since (as galaxys noted) the unlocker uses it's own SPL called SSPL and overrides whatever SPL you have loaded. However, it is good practice to throw HardSPL on their as the first step, since it protects the Hermes from having it's bootloader borked - and that is a good thing!
Hi todd_gj
There are not that many Germans on the SAP dewv Networks. Its mainly asian probably in Southern India. Most of the software is now developed out there, especially sisnce it costs $10 an hour. I bet most WM5/6 is churned out over there.
But I do take your point. You need to do your reading, but i have found a little extra help goes a long way to making sense of it all.

Asif
I have an AT&T 8525 arriving tomorrow and I'm so excited by the possibilities... but at the same time I'm just by all the different jargon and things that everyone seems to know about. I'm coming from a Blackjack which I've hacked the crap out of but this just seems so much more complicated. Anyway, hello, if you have any suggestions for someone who has never had an HTC before, please post them up for me, because I really just don't know where to start.
Thanks!

Oh god... come in sucker.
First of all, before you even start using your phone, SIM unlock it, super CID it, install Bootloader 1.11 but not 1.04 unless you have Olipro 1.02b or you have acces to KITL, then flash every ROM you can find until sleep deprivation affects your marriage your job and you forget the name of your eldest child.
Then after two months of owning a phone that almost never is in a working state, you'll get it stuck in bootloader mode just after you suffered your first white screen of death, and in desperation you will call your carrier with a string of lies and send it back for a replacement.
Then you start the whole process again...
Have fun... not.

LOL - that is funny, but a little pessimistic.
If you have hacked your Blackjack to shreads, you will have no problem.
Start with MrVanx Upgrade Guides to see the process.
Then, once you have a feel for the bits and pieces of the process, read through the wiki and forums and you will be able to sort through the threds of relavence. It is really not THAT hard once you have done a little homework.
Most important thing - the first thing you should do is upgrade the SPL to Olipro's HardSPLv7 - do that first - that way you can recover from just about anything.
Rest assured, if you have a little experience, educate yourself and follow the guides to get started, your device will work 99% of the time. Don't fret.
I am also one of those new users and my 8525 is coming in a few days but i'm a bit technical about computers so i tend to grab it quickly, i DON'T want to play around with my mobile, i just want to unlock it, then put it to some good windows mobile 6, and then forget about it till windows mobile 7 comes, does that mean i use pof's sim unlocker v3a to unlock my phone...
alternative is Hard-SPL, if thati have seen that making your phone supercid seems dangerous and the safer s true i simply apply hard-spl on my phone? (though i don't even know what it does if its a utility or a piece of code integrated into your phone or a custom bootloader ), after applying hardspl, i simply follow the legitimate official instructions to install TyTN Mobile 6 official rom as if my 8525 was a HTC TyTN?
I just want my final goal to be Mobile 6.0 Unlocked in the safest go...

How do you know that WM5 isn't good enough for you? If the only thing you want on your phone is WM6, why didn't you buy one with this pre-installed? Maybe you should spend some more time reading before you get, and break your new toy - all the best links are already posted above and if you'd read them you wouldn't be posting these questions.

That link lists no fewer than five operating systems, for one device, all WM6!!!

...head...spinning...
Thanks for the advice to everyone who gave it... I got my Hermes at 1 this afternoon and it's been sitting on my desk, charging and keeping me from really getting any work done all afternoon. I'm going to assume that all the acronyms y'all are throwing at me will be explained in the wikis...
Don't freak them out guys , get it unlock it install official go to bed happy, if you want to go crazy over installing different versions of roms all the time do so but check the safety steps first (many guides here, Mr. Vanx's is a great place to start) mind you there is no 100% safe option and most of the roms are more or less the same, you can always add cab files of things you want, it's better to stick to a clean rom. If you play with it there might be a chance you screw it... badly (even if you know what you're doing)
Me I just updated the official WM6 (which was released sooooo long later) thankfully in your case you don't have to wait.
Either way congrads on the phone and enjoy it, some small issues aside you have a great piece of hardware there.

welcome... i was like you for a while... i'm a new hermes 8525 owner too... read and learn before you really dive in... understand the terminology and jargon for a while... get used to using your phone in stock mode for a while before moving forward... being familiar with it is important... then the first thing you should install when you decide to is hardspl... good luck...
thanks again to everyone! I have to say that the MrVanx Upgrade Guides link was the best, most helpful thing anyone could have pointed me at - step-by-step instructions to flash my hermes with a new ROM. It was great. The forums also yielded CABs and all sorts of other helpful links that have set me up with a near - perfect phone.
Of course, now I'm bored. what's the next step? 'cooking' my own ROMs? where do I start with that? what are 'kitchens'? I know there's lots out there. thanks again for the help y'all have given!!!

So, I can't read your nick without thinking of the Lethal Weapon movie with Chris Rock. He was detective Butters or something. Anywa, I digress...
I think your next logical step is one of two paths:
1. Cooking and coding - either for yourself or for a new release, if you come up with something you think is different or cool for the community - home cooked customization apps are quite popular - settings backup/recover solutions too - fewer options out there for that right now
or
2. Documenting - maybe something you could work with MrVanx on if you want to pick up an area that is not well documented adn try to document it for folks
For cooking, start HERE IN THE WIKI and see what you can figure out. I am not sure if all the latest kitchen releases are in here, but it is a good start. Follow the links then do some additional searches - lot's of cool stuff... enjoy...
I would like to know why there are no cooked ROMs for the star trek.
Is it purely not enough owners? Or is there some other reason?
I think I remember reading that HTC had some kind of protection against cooked ROMs? How come only in this phone?

At the moment, there is no way to bypass the SPL lock on this phone. SIM and SuperCID unlock are no problem, but to flash a modified ROM for this phone, like all others requires either a patched SPL (bootloader) or a completely modified SPL that ignores signautre authentication of the ROM.
Some of the forum members believe that an SPL mod is possible, but testing it comes at the expense of losing a phone (bricking it). We have half a dozen or so forum members willing to take the risk for the good of the cause, so we are waiting on the developers who think they can do it to roll out some trial plans.
Rest assured, once the SPL is patched or modified, this phone will get WM6 and cooked ROMs shortly thereafter. Stay tuned. . . . . . .
How come all of the other phones it is so quick on? Is this just one of the less popular ones? It has been out for quite a while! The Kaiser was all ready to go super fast! Well, it is good that it will soon be possible!
I am thinking of getting either a Cingular 2125 (HTC Typhoon, just a Tornado - WiFi) or a Cingular 3125, since I can get it them for cheap from Premier. Was wondering which to get!
Typhoon and Tornado already have WM6. You may want to look at those. I have a Typhoon and have it running Sp3Dev's WM6 with good success. I sometimes use this a back-up phone to my Dopod U1000.

Hmm actually the 2125 isn't a typhoon. I do not quite know what it is. Maybe just a tornado - wifi? Maybe it doesn't have its own codename since that is exactly what it is?

Cingular 2125 is listed as a variant of the HTC Tornado in the WIKI. - FYI
Due to my own problems with getting informations about issues mentioned in topic, I'm posting this thread...
Idea is simple: could anyone explain strictly, what is SPL, RADIO etc., PLEASE?? The reason is, that there is really a lot of informations about it on the forum, but as they are everywhere - they are "nowhere"...;/
In advance: sorry, that I'm not spending hours on searching for answers, but the idea is to collect all this basic informations in ONE place...
Hope you will understand and won't shout at me...x)
I bet this page will answer all of your questions. All the basic information is in this one place: http://wiki.xda-developers.com/index.php?pagename=HTC_Athena

Ye, I was there of course, but sorry - no informations found about WAHT particular things ARE, only HOW TO do some things (e.g. how to make them works)... Can't find anything in "Athena for beginners" (and Athena Manual), Athena FAQ's and so on... Or am I blind...??
I have to agree with you that for noobs it can be quite overwhelming.
Here is a list of what everything stands for
http://wiki.xda-developers.com/index.php?pagename=Acronyms
The radio is the part of the phone that enables communication with the cell towers and the gps satellites. Upgrades can help to improve signal strength, battery life and gps responses.
Anyone can upgrade the radio on their windows mobile phone without making any other changes to the phone (assuming that the radio was designed for your phone and not another phone- the latter is possible but requires extra work).
Upgrading the radio is quite straight forward- select a radio rom that you want and then either put it on an sd card or flash it from active sync (xp) or wmdc (vista).
This will have no impact on the operating system (o/s) and as such you will not lose anything.
Upgrading the o/s involves wiping the existing o/s- in this case you will lose all of the info on your phone- you can use 3rd party programs to backup/restore.
There are limitations on the o/s roms that you can use. Official upgrades from the supplier/maker will be straight forward- other (better/newer) roms might require you to make your phone cid unlocked so that you can install the rom.
Here is info on making your phone cid unlocked
http://forum.xda-developers.com/showthread.php?t=315831
This will also allow you to use radio roms not initially designed for your phone
There are other considerations to take into account regarding the memory allocation in the phone. Some of the o/s roms require you to change the memory allocation- more to the o/s and less to the running programs memory. These are defined as spl1.2 or the hacked spl3.5.
To hard spl your phone
http://forum.xda-developers.com/showthread.php?t=316846
Once the above has been done you MUST ensure that the rom SPL matches the spl on your phone- I have made the mistake of using the wrong rom for my spl and ****ed up my phone before.
Should you wish to downgrade your spl then read
http://forum.xda-developers.com/showthread.php?t=405604
If you forget which spl you have then enter the phone bootloader by pressing the camera button and using the stylus in the reset hole at the same time.
You can find out which radio and o/s you have by going to settings/system/device info
I hope this helps- please ask if you need more help- it is ages since I last up/downgraded my phone so hopefully any errors here will be highlighted by others.
Be warned that no rom is perfect (not even the stock roms) and that upgrading is not allowed under the terms of the warranty and is not with out risk.
It is fun though...
Wonderful!! Thank you a lot, imaginarynumber! This informations are really usefull Only two questions at the moment...

OK, but how can I check, or is my device CID-locked or maybe not...? (I'm not the first owner, so I've got no idea...) Or maybe unlocking already unlocked device wont cause any additional problems...?

So the only difference is a size of memory allocations?? Are this amounts constant for each SPL? And so the rule "higher (version) is better" doesn't works here...?
Thank you a lot for all this work one more time...
hi mrkazor
If the phone is not cid unlocked then you would not be able to use any rom other than the maker's/supplier's rom, so for example if you had a cid lock tmobile then when trying to flash it would check the signature of the rom and if it found that it was not a t-mobile rom it would not allow you to flash it.
I believe that you can check the cid status with mtty using the info 2 command (its a telnet program).
I think that it is ok to cid unlock a phone that is already cid locked (but it would be safer to check/ask in the cid unlock post).
Re the spl, there are two allocation sets, spl1.2 and 3.5 with the latter taking up more memory for the o/s. In general the higher spl version roms have more bells and whistles but there is also the risk of more incompatibility crashes/problems with the extra clever new programs. Newer windows mobile versions will require increasingly higher spl/memory allocations.
To date I have never found a perfect rom- some are better than others depending on your requirements.
I went as far as wm6.1 from wm5 and played with many different wm6.1 roms.
At the time of writing MichyPrima has a wm6.5 that looks quite impressive.
The key thing to remember with any roms is that they are based on the buggy windows ce platform.
Good luck
You were right - dont't know about CID-lock, but I had't had SIM-lock on my device before for sure, and now I have already passed all 3 steps (Sim-unlock, CID-unlock) of Olipro's Athena Unlocker, having no additional problems And what could be more interesting: succeed even despite Windows 7 on my PC I've also updated radio to 1.57, but still having SPL 1.2... In the future will be needed 3.5 (e.g. for WM6.5 by Michy ), but I have no idea how to upgrade it Is the SPL avaliable as a file (like radio) to inclose it to RUU...?
hi mrkaczor
Sorry an ommission on my behalf.
There is no single spl upgrade per se. You need to do the ap4 upgrade which will move you to spl3.5 at the same time.
http://forum.xda-developers.com/showthread.php?t=387409
After that you can then try any of the other spl3.5 roms or if you ever want to go back to an earlier stock rom you will need the spl downgrader, found here
http://forum.xda-developers.com/showthread.php?t=405604
These forums are the best single source of info for htc owners but the info is not always as easy to find as perhaps it could be. I guess that there are very good reasons for this but that is cold comfort to a newbie. That said many of the memebers (much wiser than me!!!) are willing to devote a lot of time to helping others. I think that some of the more experienced and established members like to pretend to be grumpy sods... yet they still help those in dire needs.
Welcome to the "club".
Hope this helps
Hope I didn't come across as a "grumpy sod". I thought the wiki was fairly thorough and covered the OP's questions.
One thing I can tell you from experience - if you have 3G available in your area, you want to upgrade to radio 1.58. It has a large network speed improvement over 1.57 and all earlier radio roms.
imaginarynumber, yes - this DO helps...xD Thanks one more time

So does 3G works on your device?? Because I have it available in my town, so I'd rather have efficient video calls...
BTW. And how it is about GPS signal? How long is your device waiting for it? Cause I've had radio v1.45 before, and it took ages for my x7500 to connect with satelites:/ And no chance for that inside the building (and for example my father's Mio p560 connects even from the building, of course not too far from some windows... Could Mio have better radio than HTC??)
Hi Techntrek
My slight wasn't aimed at you, honestly. I recently revisited the wiki after not having played with my ameo for ages and found that although it is comprehensive it is not "easy" to follow.
My grumpy sod reference was aimed more at the SuperGods such as Olipro- I have seen how much hard work he puts in so I assume that it is some kinda elder statesman bravado
I think the main problem is that there are too many assumptions re the experience of the reader. As a first timer it is difficult to follow.
Some of the threads in this forum become outrageously long, for example,
http://forum.xda-developers.com/showthread.php?t=477235
The above is a thread for the touch pro- it is hoped that users will post problems there rather than starting a new thread- there are over 2000 posts- how helpful is that.
I hope that I am not coming across as ungrateful but who has the time to go through such long posts- not even knowing if their problem is covered there or not.
I am unable to provide a better solution and thus respect people such as mrkaczor who have the guts to ask basic questions in-spite of the fear of being shot down. By the same token I also respect people like you (techntrek) who are happy to help others- keep it up
-------------------
Mrkaczor
With regard to the radio options- we have little choice with regard to radios compared to some other handsets- I never noticed any real improvement in GPS- others have. I never make video calls so issues here have never been a concern.
It seems that one radio might suit one mobile subscriber more than others. It might be helpful to mention in the radio thread which provider you are with and ask others on the same network which radio worked best for them.
Good luck
