Hello Guys!
I have a JAMin G4 that a marketing company gave me for a daily survey.
It's software branded by WIND (an italian mobile provider). I'd really love to flash it with a WM6 ROM but I didnt do that because I'm afraid I won't be able to restore it as it was when they gave it to me.
So...
Is there a way to back-up my original WM5 rom, flash the WM6 and, when it will come the time to give back the Jamin to the owner, flash back my original WM5?
I've tried to find the answer with the "Search" but nothing came up...
Can you help me?
Thanks in advance,
Bodhi3

Cannot use O2 Connect after upgraded to ROM 1.06, pls help !
Any expert can help me with ? Thanks a lot !
You can still use back O2 Connect. Just need to reinstall few of the O2 crap from your old Extended ROM. Had done that on mine, and now able to connect to O2 plus able to run O2 Plus without problem. Off hand I can't recall the exact .CAB file you need to install back. Just give it a try, install 1those .CAB file one after another and test the connection to O2. I didn't note down the exact step previously, thus can't give you the detail steps as how I manage to get it done on mine. Just damn lazy to do a hard reset and start from scratch again.
Oh, great, I will give it a try. Thanks a lot.
But I would also like to know, did you backup your original rom? If so, can I get a copy from you? I didn't back it up, and I found regret about it. Thanks !
Hello,
I have a similar problem. I think it was because I forgot to patch the operator code. Can anybody tell me the operator code of O2 xdaII mini?
Many thanks in advance!
Hey guys,
I tried the WWE-ROM with BigStorage now, but I just want to go back to the original TMO Germany ROM, cuz I don't have big advantages of it but I lose my warranty...
Now my Problem:
Upgrading to WWE was just easy as described in the Procedure.doc on the ftp. But what do I have to do to get the original ROM back?
I saved it as a German.nb1. D I have to use ntrw write German.nb1 h: ? (h: is my sd-card-slot)
That way it doesnt work, the Bootloader doesnt even recognize the ROM. When I backup my WWE-ROM to the SD-card and the use that ntrw command from above, the ROM is recognized, but after having updated it, I can't bot anymore.
Hope anybody can help

Shipped rom?
Hi Stefan,
Seems like there's something wrong with your original rom-dump. Had it myself & it's a pain in the ***. Why not download the original German TMO shipped-rom & try it with the normal usb upgrade method?
Since your magician won't boot the software will probably tell you're upgrading from version blank, but that's no problem it will work. just put it into bootloader, connect usb & start the update program.
Success, M
seems to work, I'm just upgrading it, just had to put it in bootloader-mode again and start the update-utility from t-mobile.de...
will report if it really worked later on
Hi! you would do me a great favour by putting the rom on the ftp! i would really need it!
Please!
are you from germany or from austria?
greets
I don't need to upload it, its not even the most recent version (my original ROM was never, but I didn't find the original from TMO in a newer version :-( )
Just download it from t-mobile.de, I'm from Germany anyway...

The story: Received an new O2 XDA NEO from Germany. Being portuguese I don't know nothing of german idiom. I dowloded the JAMIN Eng. rom from the FTP and tryed to unstall this rom. With the ROMUpadte utility that comes with the ROM I get an error. With the ROM Update Utility_NOID the process stars and go normally until 95%. Here, after some minutes give me an error saying I can't upagrade with the NBF file.
I was a little passed out thinking that instead a phone I had a brick. Pul out the batery for moments. After I turned on the phone and it shows the tri color scren of bootloader. Ok conect the usb cable again and start the upgrade to the RUU_Prophet_2151327_21513121_021921_DOP_ASIA_WWE_Ship-NoVendorID. and voila... the process completed without problems.
The weird thing is why my phone doesn't accept the JAMIN rom?
Anyone has an expplanation for that? Thank you
can you tell me wehere i can download a jamin rom ? then i can test it with my o2 xda neo
I upgraded my Neo to jamin rom without a problem. I was using the RomUpdateUtility by machinagod, which you can find in this forum. But now I have switched to RUU_2151327..._DOP_ASIA_WWE too. To me, the new version DOP_ASIA_WWE rom works much better than that jamin. More fast, more effective. The JAMIN always runs out memories and makes the CE-Star chinese input inactive, especially when WiFi used. The DOP_ASIA rom rarely meets such problem.
Upgrade rom
You can only upgrade rom but can not downgrade. So now you are at 2.15
but Jamin is at 2.13.
Hi,
upgraded qtek s200 with RUU_Prophet_2151327_21513121_021921_DOP_ASIA_WWE_Ship.exe, using ROMUpdateUtility-NoVendorID.zip, which does not check Vendor ID.
No major issues so far. During boot dispays Dopod instead of QTEK .
Besides, few differences I found in voice diler and new program called AutoConfig. Appears, to configure automatic settings for your GSM carrier, but only for ASIAN operators, which is useless to me. No worries, interface still English.
It was mentioned few times in this forum, that you may experience some "delays" during flashing your device - don't panic, don't touch it, just wait for some time, it will finish on its own.
Good luck with upgrades.

Hello all,
I am in crisis situation.
I purchased the touch cruise (polaris) from authorised dealer in the middle east (my polaris is middle east version) came with wm6 SPL 1.28.000. ROM 0.0.415.2 (sorry I had saved the details in one of the files but I guess it got deleted. so I dont remember which ROM version I had)
I wanted to test the diamond TF3d style, so I upgraded. below is the steps I took
1. Hard spl - v2
2. downloaded _HTC Touch Cruise_RUU_Polaris_HTC_WWE_3.13.405.0_radio_sign_25.85.30.07_1.59.42.15_Ship.exe
3. installed the same.
4. Installed HTC-CA-Polaris drivers and TF3d.
5. I read somewhere that it works slow and need to upgrade Radio to 1.59.42.23. I did that.
but now my GPS is not working with Garmin also tried TOm TOM which is installed by the WM6.1 upgrade, no luck even the phone is too slow
I want to revert to the original version. please help me find the ROM download and steps to downgrade to original. I can downgrade the SPL to original but need to have the ROM first bcos I dont want my phone to be total dead.
need urgent attention from the experts.
thanks in advance

In my experience downgrading radio is bad thing to do.
When I did it, my signal has weakened radically, and I lost WiFi stability and almost lost BT.
However, hardware was not damaged, so I have normal reception after turning back to the official WM 6.1. So I guess you will need to hack your device again, or wait for newer ROM...
Oh, yeah... I never did hard-SPL...
