[Omnia 7 General] chemeng:
I'm sharing my experience with Mango update...

Omnia 7 ex T-Mobile but now unbranded

from NoDo 7392

Initially, I didn't get any update message when connecting with Zune and trigering Search update from Zune Settings -> Phone -> Update.

I tried the disconnection thingy about 10 times without success. At that point, on my phone, I had disabled WiFi and Data Connection, but I was connected to the carrier network. I disconnected Internet on the pc after 3-4 seconds. I tried multiple times altering that timeframe to no avail. Some say that u have to disconnect quickly less than 3 seconds, almost after searching for update.

My next guess was to go to Airplane mode on my handset, and after the first try - voila - I got prompted that there is an update, 7.0.7403.0, clicked OK, connected Internet back on the PC and continued with the installation. I can't be sure if getting the phone to Airplane mode did the trick or I got the disconnection timing right, but you don't lose anything trying this.

The update failed shortly after, because of low disk space on the PC (required for the backup). Estimate about 10 free GB's of free disk space on the hdd that you have installed Zune.

I freed some space connected again the phone to Zune and I got the prompt again without trying any disconnection work-around. Proceed to installation. Update to 7043 was successful and was prompted automatically to a new update, the long awaited 7.10.7720.68 Mango. After some steps, I can't recall at what step, I got a message that the update was not successful due to low disk space on the handset this time. I had about 320 MB's free before the update. Any worries for 'brickage', did not arise at all as I booted with the 7403 o/s, which was operatable 100%. At that point fw / radio / bootloader had NOT been updated.

Freed about 250 MB's of phone settings, bringing free space to 570 MB's, and that did the job. I connected to Zune, got prompted for Mango, completed update. Funny thing, that after the Mango update, free space was not lower than 570 MB's, but close to 800 MB's

So, summing up, get your phone to Airplane mode (may or may not help), ~ 8 GB's free on the PC, ~600 MB's free on the phone, and do not worry, very bad luck is required to brick your phone.

I didn't get of a 3rd update, as some have reported, the OEM update, but my firmware / radio / bootloader all have been updated to:

fw: 2424.11.8.5

radio: 2424.11.7.2

bootloader: 5.8.1.9

So, I assume, for those updating from NoDo, the OEM update is included in the Mango update.

Now running Mango, the ui is faster than NoDo, unbelievable. All apps keep on working, except for sideloaded homebrew apps that use native code and most patched OEM apps of other OEM's (but not all of them), all other apps, sideloaded or downloaded from Marketplace, homebrew or not, continue to work. All games still work, I could not spot any performance difference from removing the 30 fps cap.

In the Samsung section of the MarketPlace, or after searching for Samsung Electronics Co.,Ltd., I spotted a lot of new apps, some known, some never heard of. The apps not existent for NoDo are: AllShare (DLNA client), high fidelity position (GPS settings, adding GLONASS support), Mobile Print (I am not sure, maybe existent on NoDo), FunShot, MiniDiary, RSS Times, advanced text messages, Video Call (video calling through your operator 3G, chargeable)

A strange thing is I haven't received any pushed notification from the Marketplace to update any app. I have updated a couple manually without need of uninstall/re-install but not automatic notification whatsoever.

If you get a message saying when attempting to run an app, something like ''Microsoft has invoked the use of this app'', it means that (if you have a Developer unlocked phone) your phone has been locked; you have to repeat the Unlocking proccess with the Windows Phone Developer Registration option of Windows Phone SDK 7.1 tools. However, the maximum apps limit has been as well lowered to 10 apps (or 3 if a student dev), so I can't sideload any app (so no homebrew to assign max apps / or registry editor). Any ideas (other than hardressting and installing assign max apps, or uninstalling apps till u reach below 10 apps)
