Unable to active device on iOS 11.2

[truonggiang0710]

Hello @nikias ,

Lib cannot activate device on iOS 11.2. Please help me resolve it ? Here's log log.txt

[nikias]

It breaks down to the following error message:

ERROR: HandleActivationInfoWithSessionRequest: Request contains invalid key: ARS ({
    FunctionName = "init_lockdown_server_block_invoke";
    NSLocalizedDescription = "Request contains invalid key: ARS";
    SourceLine = 197;
})

I need to understand what the actual problem here is.

[truonggiang0710]

Do you need more detail information or more time to investigate this issue ?

[nikias]

I could figure out what's missing and am working on a solution.

[nicolassan]

Yes, same problem for US, tested with iphone 5s, DFU is Ok but fail on activation.

Do you need more datas ?

I try but it's still unsuccessful. Here log log2.txt

same as @truonggiang0710

"Failed to activate device with record."

i printed out the result plist for the mobileactivation_send_command_plist call:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

Failed to activate device with record.

[nikias]

Hmm... So the device gets the actual signature (the ARS it complained about before) but something seems still wrong. I will check again. Also @truonggiang0710 you didn't compile libimobiledevice with --enable-debug-code :)

[nikias]

I think it has todo on how we pass the activation data to the device. It is parsed from xml to plist format in libideviceactivation and then back to xml (and again to plist data) in libimobiledevice so my guess is that this will make the data not match with the signature.

ok, it's working with the 2 patches !

Ok to activate with iPhone 5s and IOS 11.2

I'm testing the other exe (recovery, info, DFU etc..)

[nikias]

Awesome. Will rework the patches a bit and push to master

[nicolassan]

We test all executables (deviceInfo, recovery, activation) all is ok for me, many thanks @nikias

[truonggiang0710]

I test with iPhone 6, iPhone 7, iPhone 8 and iPhone X (iOS 11.2), all is ok for me, thanks @nikias
