Witam serdecznie,

spotkał się ktoś z takim przypadkiem, że po wymianie LCD w telefonie HTC zapętla się recovery? Nie można przejść do systemu, po wyjęciu baterii i restartach non stop odpala się recovery. Ma ktoś pomysł, jak przywrócić system?

Hello!

Check, if any button is jammed and activated continuously.

W bootloaderze volume up i volume down działa normalnie, przyciski wyglądają ok. Nagle telefon leżał na biurku z odpalonym bootloaderem i się wyłączył i nie da się włączyć. Jak podpinam pod ładowarkę to miga się tylko pomarańczowa dioda. Wie ktoś co się stało?

In the bootloader, the volume up and volume down works normally, the buttons look ok. The phone was lying on the desk with the bootloader mode enabled and suddenly turned off and unable to turn on. As I plug into the charger, only the orange LED flashes. Anybody know what it's happened?

Najczęstszym "nieszczęściem" przy wymianie jakichkolwiek taśm, są nieuważnie uszkodzone elementy SMD w pobliżu konektorów FPC. Obejrzyj dokładnie płytę pod mikroskopem i zobacz czy "coś" nie "odpadło".
Następne w kolejności uszkodzenie eMMC :(

Sprawdź przycisk głośności w dół.Jeśli nie to odbezpieczyć trzeba s-off bootloader i wgrać rom .Miałem kilka sztuk które dostałem z recovery lub martwe miga tylko dioda.Po podładowaniu od razu recovery. Niestety po wgraniu softu po kilku dniach znowu recovery i skończyło się na wymianie kości emmc.
