Help with an Audiovox PPC-5050 .. upgrade to Win Mobile 5

Hi there - I'm a total n00b here, so thanks for your patience!
I have an audiovox PPC-5050 CDMA phone through Bell Mobility in Canada. I also have a Windows Mobile upgrade package, but am having problems upgrading from Mobile 2003 to Mobile 5. I used the XDA tools to create a rom image of my device, but when I try to restore the data, the tool reports a communications error - "cannot execute the remote communication program".
My question is - do you think I should continue trying to do the upgrade, or instead try to restore the ROM? So far, both have failed!
Thanks for any help and suggestions on how to proceed!

A google search at PPC 5050 shows me that it's a Wallaby, no way to upgade to WM5, sorry!

Darn - really??

is your device, i think it's not upgradable.
But it seems that the PPC 5050 is not a real Wallaby, it's a modified. Maybe another User has experience with it.

Yes - I saw that the PPC-5050 was based on the Wallaby .. so it's hard to tell ..

Build 10581 Downgrade Fail - Lumia 640

Screenshots tell it all:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
As soon as the fail in the recovery tool happened, the 640 showed a red screen with a progress bar for maybe half a second, then restarted itself. The same thing happened even after having build 10581 reinstall itself from scratch. This happens when using multiple computers.
If this means anything, when I hold vol. down + power when it first boots up, my computer sees the entire filesystem of the device as a drive called "MainOS."

Nokia Care Suite's Product Support Tool For Store 5 program says "not supported product" once it detects the device.
Trying to manually flash via Windows Phone Image Designer instantly fails to flash the files:

I'll try a third download, this time using NaviFirm+, which looks like it's downloading the same exact files.

Try to revert back to any working version of the issued G-app. FYI, this issue is similar to "Google keep". I have to uninstall/reinstall the previous version whenever google play updates them automatically.
Here is a temporary workaround:
Go to the below website & find your app with the latest working version https://www.apkmirror.com/ E.g.: this one for Google Keep | arm64-v8a/armeabi-v7a
Save App.apk inside the compressed file (.rar format) for later use. [&& To avoid Xiaomi Cleaner from detecting & auto-deleting]
Using Winrar apk. Install/re-install your G-app normally when required.
I hope it helps.
Anyone who has other suggestions/solutions, my ear is all hear.

MRX-AL09 Can't update to HarmonyOS 2.0

I have 11.0.0.227(C432E3R1P6) version on my Matepad Pro 10.8. I switched region to China in device settings, in My Huawei app and in App Gallery. Updater didn't find any update. I've even done factory reset and it didn't help.
Maybe there is an option to manually download and install HarmonyOS?

Same problem here, been looking for a few days on if it is possible to update to harmnoyos or not. Starting to point towards no.

Guys @mimss , I don't know how long this solution will last. Today I wanted to test an app which enables to use the tablet as a monitor or drawing pad. When I connected to my tablet to windows PC(with included USB cable) the HiSuite opened and required me to update it. I updated it to 11.0.0.650_OVE. After connecting the Hisuite with the tablet, I clicked on update, It showed me a new available update HarmonyOS2, so I hit download. now it is downloading and installing (Not done yet). A week ago I changed the My Huawei region to Vietnam also the App Gallery. so you should do it to. I also have the MRX-AL09.

Hello. I got myself a Surface RT and realized it's basically useless today. I can not even use it for simple school work... so I set out to find a solution. I ended up following a guide to install Windows 10, but now I'm stuck with this error I don't understand at all.
I cannot get the device to boot back into RT 8.1 now and am forever stuck on the Recovery screen.
Tragic, I know.
I have very little experience with command prompt, so this could be a really dumb question... but I was not getting good answers from google.
So what does this error mean and what should I do? heh-

hello
am i missing something but i see no error message on your screenshot?

With the caveat that it will still be useless with 10 on, have you tried Media Builder?
