Sorry for the question, but is there any way to buy the whole motherboard? If so, what is the name, and where can I get one?
I need a motherboard too. Did you find any place where they sell it? I bought the phone as new from China but I found out they scammed me and sold me a dodgy repaired one.
Please search for it on eBay.
I have one for sale in the UK, but since I work in a logistics department, I can ship worldwide for free! My one does not charge anymore. However, I already replaced the charging port. I am willing to sell them as parts. Don’t want to invest more money anymore. Anyone interested, message me: borosidf@gmail.com
Ditto! I got mine from Aliexpress, and it has had a chip replaced. It worked for about a week, needing an occasional power reset by reconnecting the battery, but now it’s just dead. I’m trying to get Aliexpress to enforce a refund, but I suspect they only support Chinese sellers over foreign buyers. Did you have any luck?
