PurpleRestore is a tool made by Apple and is used for flashing iOS devices. It provides far more customization than iTunes, and is known to be used to flash internal firmware to prototypes. Little is currently known about which versions it "supports" for restoring as such. PurpleRestore is installed by RestoreTools.pkg or Home Diagnostics. A CLI version of PurpleRestore is included (mobile_restore).
This tool can (and is meant to) handle multiple restores. When performing restores, PurpleRestore color coordinates the device in the table, and when the device is about to receive the AppleLogo, it will set the background color of the screen to the color assigned to the device. Like iTunes, PurpleRestore communicates with devices using a usbmux connection.
PurpleRestore 3 is the latest known version of PurpleRestore. It was initially leaked on Twitter in October 2016 (2016-10). The update sports a redesigned user interface and icon, support for IPSW files, and reveals the existence of an internal PurpleRestore wiki, which most likely requires access to Apple's internal VPN. A "Restore Issues" wiki is additionally provided.
The boot screen on the device doesn't turn purple when restoring with the tool without a debug UART cable, unlike previous versions of the tool. PurpleRestore 3 also has full macOS Sierra support, which was broken in most of the previous builds.
PurpleRestore uses "Restore Bundles" which can be obtained from a server specific to versions of iOS, such as afp://fieldgoal.apple.com/RestoreImages/ and afp://endzone.apple.com/OldRestoreImages/ (among many others). Unfortunately, these afp servers can only be accessed through Apple's internal VPN. PurpleRestore is essentially useless to the general public, because it can only install currently signed iOS versions without having Apple VPN access.
You can create your own bundles by extracting an IPSW into a folder, and restore them if they are being signed; or if you have SHSH blobs saved for an A4 device (and below) then you can either stitch or use TinyUmbrella to assist in a downgrade without the need for iTunes; you will still need to put your device into pwned DFU Mode.
Bundles for iPhones have an old iPhone icon, iPads have an old iPad icon, iPods have an old iPod touch icon (likely all taken from iTunes), Apple TV Bundles have a disk that has the text "ATV" on it, and the rest have generic folder icons unless stated in the list below.
As with iTunes, PurpleRestore can personalize builds for iOS devices (since recent Bootroms expect a valid APTicket). The tooltip for the "Personalized Restore" checkbox reads "Your ticket to the Orwellian cloud." This may suggest that Apple developed TSS in part to control access to internal build variants (i.e. prevent leaks of "interesting" builds of iOS), in addition to preventing production users from downgrading.
By default, PurpleRestore comes with three pre-made restore settings: "Update Device", "Erase Device", and "Erase Device + Wipe NVRAM". Those restore settings are property lists that define the options PurpleRestore will use when restoring a device.
One problem on older versions of PurpleRestore (common) is getting stuck at "Executing iBEC to bootstrap update". This is likely a signing error; the device may have rejected the iBEC image due to an invalid or missing APTicket, trying to use AppleConnect, the TSS server is no longer accepting signatures for the version you are installing, or the nonce has been mismatched.
If you check "Allow baseband roll-backs", disable "Allow AppleConnect", and uncheck using of LwVM under Editor, selecting Personalized IPSW will cause PurpleRestore to freeze on "Waiting for device" and creates another session with "IDLE" status. If you then try to select that new session and try the same settings, it starts the restore process and successfully restore the IPSW to device.
Older versions of PurpleRestore 3 can not usually restore newer software such as iOS 11 and up natively. However, this can be resolved by replacing MobileDevice.framework in PurpleRestore 3.app with the latest one (which you can grab from /System/Library/PrivateFrameworks/MobileDevice.framework.
+1 I have the exact same problem , windows client , right click restore option does not work says : cant connect to server , backing up works , restoring from webUI works . Anyone solved this issue ? I have no idea where to start with this .
Im thankfull for any insight or location where i can gather more data why this happens as this feature is very usefull and its non functioning is relatively big problem.
Im also keen on actively engaging in this post to get to the root of this bug.
This post describes how to change the client and server to debug logging, where it is stored and where to send it to if posting is not possible: Having problems with UrBackup? Please read before posting
I have tried to use the windows function for restore file.and another file.
Weird thing , the tex file i tried to restore it threw the error as described in the first post . The .msi installation file i t ried to restore threw no error but instead just launched as if i double clicked it ? (i have tried this twice).
Thank you i tought that setting was only for internet access , now it works with the other files but the msi , file does not open the website with its versions rather it still executes the local msi file as if i double clicked it with left mouse button .

I have selected the option "Restore previous session". Normally, it works fine, but if the last Firefox window closed before was in private mode, it doesn't - instead I get the last sessions of this private window. I'm not quite sure, but I think this behavior was different (= Firefox restores always the tabs from the last non-private window) before one of the last updates.
Sometimes when surfing, I end up accidentally closing the window.A bit of a hassle getting it back but I found a better way.When I start the browser, I drop the first window to the taskbar.I then open a second window and do my work in it.Now if I happen to close the work window, I use the first window to call it back.
That's what I would expect, but obviously in my case it works inversely: When reopening Firefox, I always get the tabs of the last closed window, even if it was private. What I want when I open Firefox (and what I got before one of the latest updates, if I remember correctly) are the tabs of the last non-private window.
I was sure I could (and did) reproduce the error before I opened this problem, but now I can't :-(. Maybe I unintentionally opened multiple regular windows and mixed it up with my private window (normally one), so that the last window closed was indeed a regular one. So I will mark this as solved until I get the "error" again.
