lxvd 5 Posted June 8, 2023 Share Posted June 8, 2023 Hi. I'm looking for a live Pro1 (QX1000) system board. Perhaps someone has a phone with a broken screen or a damaged case for sale. Please contact in DM. 1 Quote Link to post Share on other sites

Power management chip was replaced two times. After first replacement the phone was working two weeks and died in process of charging. After second replacement it died in process of first test charge. Guys in service workshop say they cannot do more without the diagram. 2 Quote Link to post Share on other sites

At least for the Pro1-X, the battery connector directly contacts the cell electrodes. Otherwise charging with an external PSU would not be possible in the way that has been shown to work. I'd be surprised if the Pro1 was any different in this respect ... 1 Quote Link to post Share on other sites
