Backup of ROM?

[WreckingBall]

Hello.
I want to change/upgrade my ROM to WM6. But I want to make a Backup of my existing from first (maybe I'm to stupid to do the Update) and to have the chance to get my MDA Vario back to life I want to make a backup of the ROM is installed at this time.

Could somebody maybe tell me how i can backup my ROM? And... How can I reinstall the ROM? I think it will be moved to the SD Card?

Thanks a lot.

Thanks for this.
May problem is that I have a "very" new ROM installed (T-Mobile MDA Vario 2.21.2.8 GER). and I'm unable to complete the the CID unlock process (the Netlock is removed allready with the lokiwiz 3a.).
If I'm entering the Bootloader and open mtty I'm .not able to open the USB port.
Does it mean I need to downgrade?

Thanks Maik

There is a newer public T-Mobile ROM on the T-Mobile website: Version 2.26.2

You need to downgrade your ROM to custom 1.05 (check the WIKI page) in order to run lokwiz CID unlocker!
I tried the version 3 of lokwiz but the only one which worked properly on my MDA was the version .2b

How ever,
the CID lock should not effect the MTTY utility. This is an official HTC procedure and should work on any WIZ.

UPDATE:
I just saw that you're talking about a german ROM? The latest public german ROM is 3.3.8 (check the german T-Mobile site for that!). If you want to keep the older 2.21 you can find it at the Austrian T-Mobile site again after downgrading and unlocking your CID

I am running the german rom AKU3.3 myself - it is much nicier than previous versions and has already some WM6 features integrated.

Ok. So I need to downgrade my Device. to do the CID unlock.
Maybe the system firewall and some other settings are affecting the MTTY issue.
I checked the T-Mobile website for the newer German ROM version.
If I check https://after-sales-service.t-mobile.de/eg_online/t-mobile/t_mda_vario.htm (what my Device is) I only see the 2.21 version and NO newer version?

1.
Go to www.t-mobile.de

2.
Click on top on the menu "HILFE & FAQ"

3.
Select on that site "Broschüren & Software"

4.
Now click on the left site menu on "T-Mobile Software"

5.
It takes you to a new page and asks you for your MDA. Don't worry if your PDA is not in the list! Just choose any PDA. It will take you to a new page and show you the selected PDA. Right underneath you will see a link: "Model aendern" - click on that link and then chose as Manufacturer T-Mobile and you will find the MDA VARIO!

Sorry for being so complicate but the T-Mobile site is set up with Flash, so, you can't just copy the link! You always have to go the loooong way! Be aware that you have to temporarely allow popup's ... !

How ever,
I will try to paste the link here to the direct download and I hope it works:

Hey the link works....
Thanks. I find out that my Device is a G4 device and I also see that I can't unCID this device... Right?
I'm a little bit in fear that something is going wrong during the Update to WM6 and I have no working Backup on my SD card.
Ok. So this steps I will do. Maybe you can currect me if I'm wrong.

1. I will perform a downgrade to the custom rom 1.05 and then I make a backup after running CID unlock.
2. I make a Backup with the MTTY
3. I will install the WM6
4. If not working I can backup from SD card and maybe install the newest ROM

You only should downgrade for CID unlocking your device! This is required for installing other ROMs than from your cell phone provider!

If you want to upgrade to the new german AKU3.3 from T-Mobile - that should work without CID unlock! You also should be able to downgrade to your existing ROM version in case you just dislike the new AKU3.3

BTW:
If you're planning to upgrade to a selfmade WM6 which you can find all over the web: I tried almost all of them! None was as stabile and good as the german T-Mobile AKU3.3! Sure, they look cute with their VISTA-style look but the functionality is far away from being perfect! Also: Lots of the ROMs are very user-personalized and contain no configuration for your network (such as GPRS and MMS) - my advice: stick to your provider ROMs, either AKU2 (which you're currently running) or the newer AKU3.3 from the link above - at least until you learnt flashing and registry hacking on your device! :)

WOW I allready can hack the Registry but having sometimes some issues with instructions here ;). Like I say before... I'm a little bit in fear... ;)

[Junner2003]

Well, it is understandable! Noone wants to end up with a brick! :)

There is always a risk in flashing devices! I do it since years now and was unlucky only once by flashing a SIM locked ROM to a Motorola phone. Haven't had any problems since then. The best thing is READING and if you can't find answers just post your question. Next to it is always helpful to check also other Forums or try to find guides in your own mother tongue!

Hacking the registry is not really riskfully - at leat the only one thing what can happen is that your device won't start up and you might lose your files and data. Other than that you should be able in any case to get it running with a hard reset again by holding CON button and Voice Dial button at the same time and press Reset.

Flashing can destroy the device because of it actually erases everything in the device; even the ROM before it writes the new one. But even here you will be able to enter in BOOTLOADER mode in most cases.

Yeah thats right Junner. Reading and asking... Since I flashed my SDA wrong I'm happy to have a Backup on the SD card to get the Image back. If this is the case I'm happy.

I installed AKU 3.3 and it's looking good and working fine.
Maybe I will downgrade to the custom 1.05 and do a backup. I only want to look how the WM6 is looking.

Are you German? Or german speeking?

[Junner2003]

The ROM backup to SD card via MTTY should work without CID unlocking your device! There is no need to downgrade for that purpose. I had hard times by doing it too. It took me several trials until it worked finally!

The downgrade is only necessary if you're planning to install ROMs from other providers or ROMs in other languages. I asume you're german, so, if you don't believe anything I say - this you can believe: the german AKU3.3 is the best out there you can find for the WIZ :-)

Like I mentioned earlier: all the WM6 ROMs you will find all over the web are user created! They are either taken off from other devices and changed around until they worked on the WIZ or just visual pepped up AKU3.3 ROMs (the one you installed now). Allthough, I did not find any WM6 out ther which did not have issues in one way or another ...

I speak a little bit german , yeah!
We have WURSTFEST here once a year with lots of Sauerkraut and beer ... :)
