[Q] Samsung Omnia 7 downgrade WITHOUT a backup? - Windows Phone 7 Q&A, Help & Troubleshooting

Hi guys,
I have done a manual update from a dev unlocked 7712 fw version to Mango and everything seemed gone fine. Until I have changed international settings I can upload my apps but after that the deployment app says the device is dev locked! I don't if the international settings change is correlated but now I really need to come back to an unlocked developer version but I don't know how to because the PC used to upgrade is no more working (HD crashing). Please help me. Thanks

You can reflash a factory ROM to your phone to downgrade (in the dev & hacking forum) or perhaps a better option would be to update your phone fully and use the new chevron unlock for $9.00 per device forever.

I've tried following the http://forum.xda-developers.com/showthread.php?t=1311682 thread twice without success. I've used TMU - T-Mobile United Kingdom from Samsung Omnia 7 Firmware XXJJ6 ALL PROVIDERS and a retail version with any luck. I wasn't able to reply to that thread because I'm a junior member but that method doesn't work! Thanks for your help anyway

[Q] HELP! Need help re-branding my Samsung Focus!

I recently unbranded my Samsung Focus on Rogers for the NoDo update, and it worked just fine. I've been reading about some OTA updates Rogers was releasing, and I didn't want to miss out on it.
I've tried using the DeBrander xap found on this site, but unfortunately I debranded using the Samsung Registry Editor so the Debrander app can't rebrand it.
Does anyone know the code I have to input into the Registry Editor to put rebrand it with Rogers?
I'd really appreciate the help!
I was just about to ask for something like this...hopefully someone can help even I want to see how the focus update goes on a att unit *well the firmware update that is*
You need to use the registry editor and rebrand it manually to ATT-US (not sure)

Please go to "HTC 7 Trophy" session and find the corresponding 7004 ROM which matches your Radio version and mobile suppliers to flash your device.
If no matched ROMs, then it's the same as Dell Venue Pro with NoDo preloaded.

With the name "The Heat" I assume your from the US.
If your talking the Verizon Trophy, you CAN NOT roll back to Pre-NoDo. NoDO was requred to support CDMA (Vzw Trophy and Sprint Arrive are both CDMA based phones)
Your only Method to to unlock a CDMA based WP7 device is to go the Dev unlock method. Spend some time looking, you need to get a developer account with MS and get a Unlock from them. If you have a .edu account, it could be free.
Chevron WILL NOT WORK ON CDMA PHONES.
This question is asked almost every day, 10 seconds in search would of found this answer. Also spend some time searching, getting a dev account is a little work but, it's not that hard to do.
Little bit more info
You assumed wrong, i live in Europe, Finland. So no verizon/vodafone. Im a little bit new to wp7 devices so could you link/pm me the correct rom and tell me how to flash it? Sorry for being noob and posting to wrong section
So is it possible to flash custom rom to non-unlocked phone?

Install the DFT Rainbow Rom or some other fully unlocked rom.

I suggest you follow this guide. It's for Focus but the steps are identical.
I'm astounded that people keep trying to use the original ChevronWP7 Unlocker tool. It hasn't worked since NoDo, about a year ago. To make it work on a gen1 phone, you must install a *very* old ROM. The crazy thing is, this was quite well documented, yet people keep trying...

Samsung Omnia I8350, os ...8773. Jailbreak or unlock
Hi Mikaelel,
Nice response! I am looking at the XDA site for several months because I also have a Samsung W with WP OS 8773 preinstalled. (model - SAMSUNG GT-I8350, os 7.10.8773.98, h rev 23.15.0.8, software radio 2424.12.1)
After reading your answer and read all the links suggested by you (actually I had already read), I wanted specifically subscribe to the forum to ask you where, in the above link, is it explained how to unlock the phone with OS 8107, or how downgrade it to 7740 SO firmware??
link 1. The WindowBreak Project - not work with 8107
link 2. WP7 Root Tools - not work because it needs Interop Unlocked
link 3. XapHandler - not work because it needs WP7 Root Tools
link 4. http://forum.xda-developers.com/showthread.php?t=1637222 - link doesn't work
link 5. Bazaar for Windows Phone - ???
So I'd like to know (and I think all who have a samsung with so 8107 forward), if there is a way to do jailbreak or unlock.
Or, if you think we can at least try a downgrade, can you suggest where to find the old firmware version like 7740?
I read that there are a number of Cooking Rom (ultrashot or mwang) for Omnia7. Nothing for Omnia W?
Thanks.

[Q] How can I get an official update from a device with a ROM demo?

Hello all.
I recently bought a Samsung Focus S (i937) on eBay, but the equipment was a mobile phone demonstration of a store, and as such came with a demo ROM (7.10.7739.25), now I want to install on it a normal rom official, can someone help?
My best bet is trying to find an official ROM for it up here, and then flash it.

There is no way to install ROM on this device.
In my opinion, the only way out of this demo version would be to find a CAB file leading to update.
Here is a thread where you can find official ROMs and flashing tools with complete discription.
http://forum.xda-developers.com/showthread.php?t=1306415
SparkW (Verizon Trophy) users had this problem. For the longest time, the only leaked flashable roms turned our phones into demo models! It was terrible because the device would reset itself every day at midnight, and all your data/programming (this is a CDMA phone after all) would be gone!
We where finally granted a solution in that a full Mango rom leaked before Mango's release to Zune, so we could finally "un-demo" our phones. It wasn't for a few months after that that DFT added support for SparkW with their unlocked bootloaders.
If you cannot find a flashable rom, perhaps your phone has an unlocked bootloader available? With that, you could possessively flash a 3rd party rom. I don't know anything about Samsung phones, so I don't know how useful my input is. I do understand how manually pushing updates is a waste a time (it really is.. just a complete waste) as it won't remove the package creating the demo.
Looking at the Samsung Focus S forum.. how is this device not a legacy/low use device on xda? The Spark/Trophy forum is way more active then this?! ;

This thread has nothing to help me.
I'm there to ask questions and nobody can.
Sent from my SGH-i937 using XDA Windows Phone 7 App
With the new updates for wp7.8 had news for the Focus S?
Once the zune doesn't update the device, it can be possible to obtain the update via the SevenEighter?
I've tried but without success.
