Tak Google po chvíli přemýšlení našel toto:http://www.3q-int.com/support-2/Where can I find the firmware or manual for my device?Most issues are solved with a software or hardware reset. Replacement of the firmware rarely solves an issue and therefore should be a last resort.Please see below on this support page for a firmware download of some recent 3Q tablets and smartphones.We, 3Q International AG, are the Swiss Intellectual Property owner and headquarters of the trademark / brand but we did not manufacture products. We licensed the manufacturing rights to a licensee that unfortunately declared bankruptcy in 2014 without providing us a copy or download location for their firmware or manuals. Therefore unfortunately we are not in possession of all firmware or manuals for all previous models and can only provide them for some models produced in 2014 and later. We sincerely regret this unfortunate situation and apologize for the inconvenience if the firmware of your device is not available on our support page.You might find a firmware or user manual by contacting your local dealer/reseller who should fulfill his legal warranty obligations and make a copy from an identical model as your device. You also can Google your precise 3Q tablet or phone model and add ‘firmware’ to your model number Googled. Finally, if none of the above suggestions provide the firmware or manual, consider writing an official request to the previous licensee, manufacturer and importer of the 3Q products: TRINITY GROUP CZECH, Mr. K. Gustov, Na Radosti 399, CZ – 15521 – Praha – Zlicín, Czech Republic. Tel: +420 257 220 840 – kvg@trinitygroup.cz – daria@trinitygroup.cz.
