Downgrading from TMob 1.72 in order to upgrade to NEW o2 1.7

I've looked for this extensively now but can't find any definitive guide / advice.
I upgraded to 1.72 Tmobile on my XDA2 and of course, now I've done that o2 have released a major update too. I now need to downgrade the phone back to 1.60 or 1.66 in order to then upgrade as it won't allow anything new to be installed - not even the Application Suite will install.
Can someone point me in the right direction to find out the best / safest way to downgrade it?
Many thanks
Anthony

you don't have to downgrade (in this situation not so easy), you have the country code problem. You can search on this forum how to change the country code of the new O2 release.

Thanks for the reply. Just to clarify, if I run the upgrade downloaded from o2, then I get a message saying the program cannot be run as it wasn't designed for my device / software or something. Is this consistent with having the country id problem?
Cheers
Anthony

Sorry ignore me, I've just realised it says in big red letters about it being a country id error.
Cheers, I'm reading dcs's solutions as I type this.

Rom was for XDA II's. PDF on website said get restore rom but i cant find a link to that anywhere anyone got a o2 restore rom? i can try?

xda_IIs_LaunchROM_v1.12.162_178.exe is the restoration ROM
is it an original O2UK? operator id O2___001
did you do another upgrade prior to this one? Then it may have overwritten your operator id in your xdaiis
xda3nbftool, ER2003EDIt are useful tools
http://forum.xda-developers.com/viewtopic.php?p=78053#78053

i had same problem with you, just do the update again ignored what displayed in the screen.

ANYHELP??

Maybe this needs to be clarified on here and made into a sticky. The SourceO2 rom has been listed in error and calls to have it removed or even tested to prove its wrong are being ignored. Subsequently people such as yourselves are finding your devices have been turned into bricks! (Luckily not forever :wink: )

Unfortunately as far as I know there is not yet an official O2 rom for the Blue Angel device that is freely downloadable. But you will find in this forum roms from other operators that can be made to work as a perfect replacement.
Ash

Can anyone with new XDA2s just do image of all files on the XDA and affter that we may just upload that to these bricks wich we have now?
Please

Well my units gone bak to o2 to reflash if i can do a back up of the rom for the forum and its needed if somone told me how to i would certainly do that and upload it somere
Russ

How much it will cost and how long it will take to refresh tat in O2? An what reason You give to them?

Fixed?
Hey
Just got an e-mail back from source O2:
Hi Ashley,
apologies for the incorrect file published and thank-you for bringing it to our attention.
The error has now been rectified & I can assure you, tested. Its is available at the same link as previous;
http://www.sourceo2.com/O2_Developers/Devices/O2_Xda_II/XdaIIs_launchROM.htm

Anyone with a Blue Angel (XDA 2s, MDA III, PDA2K) like to see if re-downloading this and trying it works?
Ash

It is installing but we will see if it is working after 20 min.

Ok it is working properly
Thanx for help

hmm
Well iv told them it just stopped working. Am still under the 14 day period so I can cancel with them for any reason I see fit. Said it be 7 days, so free.

Hmm
Well I guess us and few other will be back with our XDA II's back with o2 Rom.
From wot iv read the to have ROM is the I-mate one. But am scared to try this now. Does it drasticly get better on this rom.
Scared Russ

MDA PRO ROM upgrade

Hi all
My first post as a new MDA PRO owner HTC universal if I am not mistaken.
My question is that I am with Vodafone UK and am tying to flash my device with their latest ROM downloaded from their site.
I keep on getting the following message from the setup program i.e. "ERROR 120 COUNTRY CODE ERROR" 38-38-44-44-44.
What am I doing wrong as I thought these machines were all the same! Or is it just an attempt by Vodafone to stop me from putting their ROM on a Tmobile phone. If it is is there a work around?
Thanks in advance
Brian.

There are 2 ways to get it working.
1. Use MaUpgradeNoID Utility
2. Change some parameters with BAL666's HTC64 Tool
If you search the forum you should normally be able to find a manual for this.
If not, do not hesitate to use the Wiki:
wiki.xda-developers.com
section Universal

Thanks for that much appreciated

As I am new to this I think must be missing something as I have tried using MAUpgradeUT_NoID with no luck. I have also seen on the threads here about MAUpgradeUT_NoID_886 but cant find a download link for it.
If someone could give me a real idiots guide would be most grateful.

All done managed to get my thick head around it.
Just like to say what a great site this is and reminds me of early Psion days.

check buzzdev.net register there and go to the download page.
If you know something about computers, then try to reset the parameters. this was working for me! the NoID.exe doesn't look for these parameters, but that doesn't worked out for me.

How to help: Installing T-Mobile WM Upgrade on non-branded S620

Can anyone post a step by step how to on installing the T-Mobile WM6 ROM on the non-branded Euro version of the Excalibur?
I've tried a couple of times following pieces of info, but unsuccessfully.
Any help greatly appreciated.

Second that....keep getting "invalid vendor id" even though it is sim/cid unlocked. Won't even run the bootoader! Help!

sounds to me that the CID unlocking might not have been done properly
let's just say that the ROM/bootloader in question isn't the problem ... YOU SHOULDN'T encounter the "invalid vendor ID" message whatsoever ... because that's what CID unlocking does !!!

As far as I know there is no way to CID unlock the HTC S620 yet. However IMEI check have a work around to get the t-mobile WM6 Rom on there. The instructions are on the forum somewhere but I can't seem to see them right now.

not a workaround ... very straight forward and works !!!
I paid & followed their instructions here and it works straight up:

and then followed this particular post ( not others workaround ) ... and now I can upgrade/downgrade WM5 <<--->> WM6 whenever I pleased:

Ok..I used GSM Liberty to unlock the HTCs620. It is definitely SIM unlocked as I can use any SIM I want to. I have seen the IMEI-check work-around & am hesitant to try it because the work-around includes changing part of the ROM code to read IMEI-Check. Not sure how that would work with a GSM Liberty unlocked phone. Does it matter? Anyone know for sure? Anybody else used GSM Liberty to unlock their phone?

So UnicornKaz, you have a Tmobile Dash then? I'm pretty sure the first post in this thread is talking about the HTC S620, although he uses the word "unbranded" which is weird.

I have the HTC S621 (Rogers Canada ) ... which is the same machine as S620/Dash/Dopod C720W ...etc
They are the same beast ... just market brand in different part of the world.
It came originally locked with Rogers carrier ..etc ... then I went to the above link and paid for the CID/SIM unlocking service .. plus I went on to do the AppZ unlocking myself ... Now I can upgrade/downgrade as I wish ... no problems whatsoever.
...except for the bugs of each indivual OS .. LOL
Non-branded meaning the phone having HTC's logo instead of the carrier's branded logo
mine is also non-branded.

All I can think of is that imei-check have updated their software and now it is a real CID unlock. When I first flashed the WM6 imei check sent those hex editing instructions in an email (your first link) and that worked for me. So people should probably ensure they unlock with IMEI checks latest version and try that second link with the instructions if your phone really is super cid. If you still get invalid vendor then give the first link a try.

I've figured it out. The instructions you are suggesting involve downgrading the bootloader from 1.19 to 1.11. Where as the instructions that imei supplied don't require the downgrade but do involve the hex editing.
I just tried UnicornKaz's suggested technique on a Rodgers HTC-S620 and they worked fine, so that way seems easier to me. It seems when you flash to WM6 it updates the bootlooader to a newer one again which doesnt show the red text on black background at startup.

don't forget to use it again when you do the downgrading to WM5
makes for easier/error free ... to run it everytime !
and keep in mind that after each ROM upgrade/downgrade ... your phone needs to be "app unlocked" again

do you even need to pay imei-check? Perhaps it works withthat boot loader without even needing a cid unlock!!

I'd already did and make sure mine is totally customizable ... perhaps someone else can test that theory of yours ...

Hi All, I've ordered euro version from amazon and they sent it to my relative there, who came here to egypt, now I found it is T-Mobile version, so I can't get arabic rom, or install programs, (when I do it says "can't be opened either not signed with a trusted certificate or one of the component can't be found), also I'm unable to sync, when I connect nothing happens although I have WMDC v 6.1, sorry for being noob but this is my 1st winmo device

If they sent you the wrong version, then they are at fault and should allow you to return the device for a refund or exchange it for the correct version. If you are at fault for not reading the list thoroughly enough, then your simplest recourse would be to learn to flash a custom ROM. This would allow you to install the language support you need. If that will be your direction, then read the thread HERE to learn what you need to do.

Thanks so much, no it's not my fault, it's their's but I'm now in egypt, and it's too hard for me to return it back, (also there's a few governmental problems here), most of the problems up are solved now, but I'll try to flash a custom ROM, so any suggestions on the best one that I can use with T-mobile version?

There's no such thing as a "best" one. There is a link in my signature that will point you to most of the ROMs available for this device, however. Basically, just flash different ROMs until you find something you like. Asking for the best ROM is like asking a stranger what the best pants are. It varies based on opinion.
