[Q] Please help with downgrade to Official Windows release - Windows Phone 7 Q&A, Help & Troubleshooting

Hey Guys,
SO i upgraded to 7712, Its pretty nice, however, there is no Chevron Tool that will unlock this build. Also, cannot edit registry either. And the last thing, I really don't like the "Not for Resale" screen when booting up.
Can someone show me a guide on how to revert back to the original OS that AT&T will support if I need their help with anything?
I have searched, but maybe i am missing keywords.
Thanks!

Just use the backup you created during the upgrade procedure.

[Q] Need LG Panther & Samsung Taylor Users' Help For Updates

So it seems like we'll need to fight over at the Microsoft forums if we're to try to stay up-to-date. I need you to contribute to my post over at msdn here: http://forums.create.msdn.com/forums/p/78753/476964.aspx#476964
Maybe if enough of us hit'em, we can get some kind of answer. Dev phones should have been the first to be updated.
Still no updates for Taylor.
It says in the forums that you linked to that there will be no updates for the Samsung Taylor phones.

Seems like there won't be and update for LG Panthers either.
Anyone wanna trade for an Android device?
Might be a newb question here but....
Did people have to pay for these developer phones? Or did MS just send them out to registered/respected developers?
I suppose, you can flash your phone with the Omnia 7/Quantum ROM at your own risk.

I would like to give th Quantum ROM a try , but I do not know where to start. I am a Bell user in Canada so I think they have the Quantum. I used to flash old WM and Android Devices all the time, but WP7 is new to me. Anyone have a thread or no if anyone has sucessfully flashed a LG Panther to anything else? I can get into a bootloader, but it is probably just Microsofts bootloader.

Looks like it's really possible, because i succesfully connected to the phone using QXDM, and even downloaded NAND's image (it's raw, so for extracting page size required, because size in the partition table is relative to page size). Though may flash it, i think bootloader will work. But you probably can get bricked device. Unfortunally i have no enough time for explorations.

I think flashing the unbranded Optimus 7 ROM would be the best bet for us. There is a registry key named "HasKeyboard" that's defaulted to 0 that we can change to 1. That might be the way to go. Also I'm wondering if we'd have to go the goldcard method to move over to a Quantum or Optimus rom.
The problem is I don't have another phone and there's no MTTY process to unbrick our phones so I'm a little hesitant to try.

Goldcard isn't required. Only HTC devices require it.
I've dumped my ROM, so if bootloader will work (i hope), device can be easily flashed.
Is anyone wanna to try? QPST can flash certain partitions (looks like only dsp1 and efs are required for succesful update). Unfortunally i can't risk my phone, because i'm developing an application.

Not being rude, but are people complaining that a phone that they received for free is not getting the update and not being continued? If you never paid anything for it in the first place, what are you out then?

I am not sure if it is worthwhile attempting a flash. The problem is we are all developers and having no device is probably not worth the risk. I have not flashed anything WP7 so I am pretty hesitant. Is this the link to flashing info you guys are considering?
http://forum.xda-developers.com/showthread.php?t=935605
In reading the other threads, there is no real confirmation on the Panther not getting updated. It is clear the the Taylor will not. I am curious if we are running the exact ROM that another device is? If so, ROM from those devices may work. I am trying to remember what the download name was (was it Pacific or something?). I deleted the file. If I still had it I would consider giving flashing a try. I wish Microsoft had not shut down the microsoft connect site for these phones. Any thoughts?

I got mine off of eBay due to it being the best keyboard phone out at the time (the Quantum is a joke), so it wasn't free for me. Once we get a HTC 7 Pro here that's compatible with AT&T's 3G bands, I'll switch over to that.

Well there is going to be a point where and update or feature will make our phones aka gw910 or Taylor completely useless as for development or testing, so this is something to consider.
Yeah connect has been down since a long time ago I have been struggling to find the FW file provided in the msdn/connect/internet forums, I’m guessing the only way now is to contact either a developer/evangelist/god/msdn who has that file available in storage, with the firmware we can create our own updated custom FW way easier than creating one from scratch and/or experiment with other FW like the optimus 7/Q.
And idea can we consider spoofing the gw910 to an optimus 7/Q .7004 using the registry editor? Making ZUNE update just the components needed.
also im willing to give it a go flashing mi gw910 UsellesGuy any info on how can i dump mi firmware. and posible explanation as in how to recover.I read the bootloader post before but is there anything else i need ?

Microsoft delivers updates using binary patches, they apply only to concrete file version, else they will be broken (or updating will be failed).
Thank you, but i think better way is to wait a bit, until situation about updates will clear up. If update will be not received - i'll begin my work

On twitter I've tired contacting @winphonesupport as far as our phones being updated. They replied: "Let us see if our team knows and we'll get back to you. ^EB"
I haven't gotten another answer back yet. I doubt I'll get one at all honestly.
quick question about updating a developer device
Hi
I'm a complete newby about wp7.
I've two Optimus 7 in my possession that seem to be developer devices.
Here the phones info:
OS Version: 6516Mainline
SW Version: LG-E900AT-00-V08d-ORG-UK-JUL-24-2010
HW Version: E
More info:
OS Version: 6516Mainline (buildlab).20100713-1228
Firmware revision number: 0.8.4.10
Hardware revision number: 0.1.5.0
Bootloader version: 1.4.1.0
Chip SOC version: 0.30.2.0
Now I've tried to update the firmware like in this post:
http://forum.xda-developers.com/showthread.php?t=935578
But it doesn't work (LGDP2 connect to phone start the update but give the error 1002)
Is there a way to flash these phones to be like normal phones? (I don't intent to develop on them) Or my hardware version is to old (prototype)
Thanks for the help

so you are relying on a dev phone that MS was gracious enough to give you as your only device and are complaining that you didn't get the update???
edit: after reading your replies, this wasn't a publicly released phone, so if you don't get the updates, I don't feel you have a complaint.

Downgrade Samsung Omnia 7 Gen1

Hi All,
How can I downgrade my Omnia 7, I've tried the Cab Sender but it remains on the crapp KK2 update not allowing me to interopt unlock.
Is there any easy way if I don't have a zune back up? I just want to go back to a previous version so I can unluck and internet share again
Thanks for the help!
Regards,
Niels
There's a flashing tool for Samsung gen1 phones. Flash an older stock ROM.
Why don't you have a backup?
My laptop crashed where it was on, didn't have it backed up... didn't think it was that important.
Can you share where I can find the tools and stock rom ?
nvm, found it.. took a few hours to get where I wanted but I got it all working again including Nokia Drive 2.0
Cool, glad you found it.
Generally, in Q&A threads, it's nice to do two things when you solve the problem:
1. Add the tag [RESOLVED] to the thread (you can do this by editing the original post).
2. Post the solution (in this case, the link to the flashing too). It would be great to have a single post I could point people to, and say "this person did it, here's how you can too!"
Hi Niels, I have the same issue you had, just got my Omnia, updated to 8107 with no backup, you have a link on how to downgrade from KK2 so I can unlock ? thanks for the help !

[Q] How can a 7.5 backup be restored after a Nokia Care update to 7.8

I guess as the title says..
The phone in question is a Lumia 800
A backup was made of the phone before it went to be fixed. This was running 7.5.. i got the phone back and upon trying to restore to the previous point i just got into a reboot loop. After talking to Nokia they say that they reflashed the phone to 7.8 and in the process disabled the restore function.
The reason for the fix.. a dislodged proximity sensor.
Can anyone here please help? I desperately need the information contained in the backup.
Thank you
Anyone have an idea how i could downgrade the software?
Thanks

i won't be of much help, as i know next to nothing.
but i do remember reading on the forums supposedly the files are kept on your laptop in one of the zune folders, so if it is simple info and short amount of data like contacts, or sms and stuff, you may be able to directly access it with some kind of desktop software, notepad etc. And copy it.

[Completed] [Q] Re-installing stock android

Hi guys, I'm pretty new to rooting so tell me if i need to give more info etc cause I know i can be a bit vague.
So I rooted my phone no problem via the all in one kit thing and installed cyanogen, but this was right before the big android update so I wanted to switch back and update to that, but somewhere along the line i got rid of all the Roms (I think)
The stage it's at now: I can boot normally but the startup wizard fails, I assume this is because the stock operating system isnt hooked up to run, regardless I can't find a copy or figure out how to run it. (before my TWRP seemed to stop running on startup)
Bootloader: I don't know how it ended up relocked after I'd unlocked it but am guessing that is why i cant access the custom recovery at the moment (twrp)
If anyone is able could you walk me through, or point me to a guide to show:
How to unlock a relocked phone,
How to get a Stock version of Android (anything after 4.0 I guess because it will auto update?) running on there
Tell me if I'm being dumb in any part of this (apart from pissing about with things I don't understand, haha)
OK, So i'm unlocked and back onto TWRP, that was easy though, What I do need help with is working out how to install the factory Operating system again, last time I tried that is what caused the relocking etc so any help would be amazing.
Thanks, Simon

Sorry yes, meant to close this post now that this particular problem was kinda sorted but didnt get round to it last night. Unless you know a way to get the correct firmware for the wifi? Just seems strange it'd update wrong.

Umidigi one plus - fingerprint. Please help!!! Please help!!! Please help!!!

I tried to install custom rom an root my new UMIDIGI ONE PRO Android 8.1 Oreo. I couldn't root the phone because it was impossible to mount data partition. No tutorial could help me. However I installed the rom, (I got from the official website of UMIDIGI), the phone is still not rooted, and the worse about all ist, THE FINGERPRINT FUNCTION IS MISSING FROM SETTINGS. And there is no installed "com.fingerprintauthentificationservice installed in the apps. I guess the installed rom doesn't include the fingerprint. Unfortunately, I apparently lost my backups trying to fix the problem with twrp. Could anyone help please. Is there any custom rom for UMIGIDI ONE PLUS sopporting the fingerprint or does anyone know how to fix the problem? I would be very grateful. Thanks in advance
I think that the only solution as of right now is to flash the stock rom.
And if you still need help will root and TWRP give me a heads up, maybe I'll make a post about the whole process.
It's quite tedious but it can be done, and it works great.
Thanks but I tried three difeerent stock rom versions without satisfaction. People said it just gone because I've formatted the whole flash memory (Formatt all + download).
