Kdybyste to nahodou nekdo zkousel, tak je to velka legrace - upgrade WP 8.1 na W10 mobile, Lumia 1520.
1. Baterka 100% nabiti stejne nemusi stacit, pac je stara, ze jo. Takze otevrit telefon, najit vyvody spojeny s konektorem baterky, pripajet na ne draty a pripojit jinou Li-Po plne nabitou na 4,2V . V mym pripade 2x18650 2700mAh+StepDown.
2. Prehriva se to. Takze odlepit telelnou pasku z kovovyho krytu procaku, pridelat chladic a cely to strcit do lednice, jakmile se uz updatuje.
