I am in US, have HMA-L29 (confirmed with customer service this is Singapore version), and I am stuck on May security patch. Current version is 9.0.0.270. I tried change Hicare region (China, HK, UK, Singapore etc.) but failed all. I contacted customer service in Singapore, they say I need to insert local (means Singapore) sim card to receive update. I contacted China customer service they say they can't help because they only support Chinese version. I guess I will never receive any update unless I move to Singapore... SH******T.
