It has now become a trend among manufacturers to take advantage of the popularity of one of their smartphones by launching a mini version of the device. Samsung started this in the past with the Galaxy S3 Mini and later with the S4 Mini. HTC, a major competitor of the Korean giant, caught the idea and came up with cut-size version of its most popular device the HTC One. And now the company has come up with a maximized variant of the One with a whopping 5.9-inch display to counter Samsung’s Note line phablets.
The HTC One Max has the same premium feel of its predecessor and it’s impressive too but, at the same time, it is pretty bulky. It’s the heaviest phone I have ever carried!! Anyway, if you have this big avatar of the HTC One and are now planning to get rid of its locked bootloader and root it, the present tutorial will help you do that easily. Besides rooting the One Max, we would also tell you how you can install the ClockworkMod or TWRP Recovery on your device.
Before you proceed, please be informed that gaining S-Off and root access on your HTC One Max will void its warranty. Moreover, the method given below is considered risky too. That’s to say, it can send your phone to a state of bootloop and might brick it. Whether it be case of success or failure, you’ll be solely responsible for the same. A good tutorial always requires a good follower. The procedure has been duly tested and found working, so just be careful while doing things.
