So, I had the Mango RTM 7720 running on my Samsung Focus, but it wasn't ChevronWP7 unlocked. Wanting this, I made a full backup of my phone using hx4700 Killer's backup too. This left me with a 19.5GB folder, containing my entire phone's contents backed up. So, I flashed back to 7004 and after a lengthy and ridiculous process I am now back on 7720, but fully unlocked this time.
However, when trying to restore from the backup I made on 7720 before, both the Backup/Restore tool and the Zune software give me an error. The Backup/Restore tool gives me a blank error message, and the Zune software says an error code of 801812E0. I've tried this restore on two different computers, with every version of the updatewp.exe tool and the Zune software imaginable (4.7, 4.8 betas, 4.8 release) and nothing works at all. I was just thinking though, if I get the restore to work would it just leave me with a locked Mango again? Or would it retain the unlock? Either way, please, what can I do to get this restore to work?
Please, does anyone know? I'd like to have my phone back, hahaha.
If you get it working it will be locked mango again as pone is restored exactly as it was prior to back up.
I had no issues with the tool. To restore back up I use 1.8 tool and Zune 4.7.
Move your mango back up file somewhere safe.
Use the tool to create new back up of current device state.
Disconnect from the internet (stops Zune auto update to 4.8)
Delete current back up file (or move somewhere safe if you want)
Move your mango backup to the correct location
Use Zune to restore back up
This has worked for me but can't guarantee it will for you

as flashmaster correctly states, you will get your locked Mango back. At this point you have to make the decision whether you want your media back from your previous backup or not. If you do, roll back (if you can) and sync your media to the PC. Once your media is backed up, restore the current state of Mango back to the device.
Make sure you make a complete backup of your current state before you do anything else.
I suggest you use v1.4 or v.6 of the tools and the latest (4.8.2345) UpdateWP.exe, Zune.exe) to make the backup. If you read the latest posts in Heathcliffs thread you will see that some of us had problems with the switcheroo the v1.8 does with files.
Only trust backups that give you a completed message and that you can unplug the phone. The phone needs to reboot itself. If you do not get these, then your backup is hosed (somebody bricked his phone restoring such image, see thread latest posts).
If you do not care about the media on your old Mango backup and you already have your media backed up to the PC I suggest you stay with the current Mango and only make a backup of it.
good luck
I have now run into problems with 1.8.
I would go with prev post comments and use 1.6. I've had a much smoother experience using 1.6

i am using jade/touch 3g
today i install the latest rom update from Asia and full restore my backup date
i am using SPBack up software
i notice i cant connect to windows update anymore.
it says something like cant connect to update server. check your data connection setting and ensure the device date and time are correct
anyone can help pls ?
Uh, I can't quite remember the last time this feature worked.
Actually, I believe Windows Mobile Update hasn't been used once by Microsoft, which renders its whole existence useless. In fact, this function has been removed from my custom rom.
So, my question to you is: was it of any use to you before? And another question: can you connect to the internet?
i can connect normally
and what the use? i not really sure as i am not so techie here, anything can be press to update i just press?
how about ms word or stuff? yes i use it rarely but i need windows as an os right? if not i not sure can my phone started?
pls enlighten me
You will have to hard reset. You cannot make a full restore on two different roms. Only restore the pim.
thanks PauloJ5
does it work if i
a) full back up now and fully restore again?
b) clear storage?
I fail to see why you'd want to use windows mobile update.
if you flashed a ROM of your choice and restored a backup, what else would you need windows mobile update for?
So, I had did the Nodo update and all. But wanted to unlock my phone with Chevron and then come back to Nodo. Of course Zune created a nice backup of my phone before it did the Nodo update. Here's my dilemma. Once I unlocked again and everything I plugged my phone in and tried to restore the backup before I did the Nodo update. Problem is, the restore keeps failing with error code 801812E0. Any ideas as to why? It goes through the motions and stays stuck at 0 % and just reboots after a few mins.
I have the same problem I need help! I got no access to my phone, I only got it 2 days ago!! Im only 15 and If I tell my parents they will kill me, Please there has to be a fix someone answer
try the official MS support channel http://answers.microsoft.com/en-us, they have a twitter account too, they are quite active with it. You might get a reply from them

Yup. I think we are screwed. Mine is in the same boat, cant restore.
big goof on my part, I never secured my backup before or after I installed Mango, I uninstalled my zune 4.8 to re-install back to 4.7.
? I have another phone with NoDo, is it possible for me to upgrade the NoDo phone in order to get a new back up and restore both phones back to NoDo

Backups are device specific. So you can only use the backup for the device it was made from.
You may want to use some disck recovery software and see if the backup folder still exists. That will be the eaisest wasy to gte the phone back on NoDo.
Option 2 is to contact MS and use their service to get the phone back on NoDo. The instruction sheet that came with Mango Update has the details.
You will probably have to flash a new rom. It tells you in the beta2 pdf in big bold letters to secure your backup, shame on you I have mine backed up to 3 locations, maybe 4.
Why did you remove zune 4.8? Did it not work with your nodo device?

my windows device manager would not start and my unlock phone (nodo phone) suddenly stop allowing me to sideload, so I did the uninstall, then a light pop say check for back up I looked and it was gone. no power outage just outage just gone weird. no restore point, glad it wasn't my main phone but now I can't sideload and no way to go back to day one, at the moment anyway.
where is the best place to flash my rom at, thanks in advance

check here . yours should be the one with TMOUS. check further in the Forum, there may be a NoDo rom, so you don't have to start from the very bottom.
might be in luck
got damn it the sd Card just went up in it what does that mean
My HTC HD7 has a memory card failure. I return it to factory and now I have the mother board replaced and the phone comes with a new serial no.
Now I have the device with OS version 7004. Is there any chance that I can restore to the system backup that I’ve done during the previous update to 7720?
You've already tried to restore the backup and it failed? Then I think there's no way to restore it =/

Have you tired the old restore file? I was wondering if the restore files are device specific also because I have a new phone but lost the restore file for it. I still have a restore file from an older phone (had to exchange phone because of hardware problems).
Sadly no. The backups are device specific and will not work on other devices. You have to start all over again.
If you use the same windows live ID u used in earlier device, then your contacts will be reupdated. ALso from zune you can view your previous purchase history and reinstall all those apps.
I've been having issues on my phone that are just pointing me into a direct that I should just reflash the stock rom to my HD7 and let zune do my updates to the current release (i've forced updates in the past and ran a few things as test) and my phone differs on how it handles "things" than compared to my wife's phone which I haven't forced any updates on.
My quest is, can I do a backup on my phone and restore it after I downgrade and update after? I don't want to have to go through the process of having to download all of my apps over again. My phone numbers are stored online and my pictures can be restored no problem. I just feel I have issues that may be driver related on my phone.....
Blah blah blah... long story short.
Set a backup.... Flash original rom (however I figure out how to do that) and then restore from the backup.
Happy new year, and thanks for any of the help.
