Hi. Thanks for the precise and practical guide.
I haven't rooted my Icarus E653 yet, because I've just bought it, and I don't want to void the warranty immediately. Hence my question. Is it possible to unroot the device without leaving any trace that it has been rooted, in case it has to be returned to the shop for an hardware problem? If yes, how?
In section 6, How to unbrick your device, the guide explains how to replace the original ROM with a new IMG. But there is no IMG file for the Icarus model. Is it available somewhere? Or can I safely use one of the Boyue images? In that case, how can I determine if I need the T61 or T62 image? I guess it's the T61, right? Also, how to know if I need the "A", "B" or "C" variant?
Also, the guide explains how to update the device to the latest firmware, and gives links to the update.zip files. Great, but I don't know if I have to update my device. Since I've just bought it, I suppose that it is up to date, but who knows? It runs Android v4.2.2 and the Icarus firmware v1.1.0-2015060820. Unfortunately, trying to update the firmware the official way (from the Settings -> About -> Update -> Check Update Version ) doesn't work. There is always the same error message: "Server threw an exception. Please try again later." I have reported that problem to the Icarus support, but I haven't received a reply yet. Therefore, I wonder if I should try the update available in this thread. But here, there is no version number, and therefore I don't know if it is more recent than mine. Someone can tell me how to find the version number within the update.zip archive? I don't want to risk to end up with an old firmware, especially since it seems impossible to download the latest version officially.
Thanks in advance for any help!
