My Xperia Z3 Compact purchased from Kogan (singaporean stock, singtel software on phone) stopped booting the other day, and their PC Companion software won't touch the phone. After contacting Sony to arrange a repair, they said that it isn't possible due to the phone being non-local stock.
What are my options?
I would go back to Kogan and try to make it their problem by pointing out that Sony won't touch it 'cause it is non local stock. They might come to the party as a good will gesture. (Worth a try anyway). Not sure why people persist in buying "grey imports" through places like Kogan. Even if you can convince the manufacturer to do local repairs it is usually a hassle.
