I read a paragraph in this <a href="Samsung Electronics considers splitting firm in two - BBC News">news</a> website and I am not sure about the 3 -ing form of the verbs (failing, leading, catching) in the mid point of the paragraph.
> In October, the company was forced to stop production of its flagship smartphone model after failing to resolve battery problems leading to overheating and the devices catching fire.
The first question is that Is there some missing words between the word `after` and `failing`, like `after it is failing to resolve battery problems are leading to overheating and the devices are catching fire.`
The second question is that can I change the verbs to simple past tense? `after failed to resolve battery problems leaded to overheating and the devices caught fire`
