Dear Everyone! First and foremost, excuse me for not speaking Polish!
I am too in need of an original Telekom ROM. As the community in my country for this phone is not that great, I must look elsewhere. I tried installing the given Telekom backup, given in the previous post, but every time I try to restore, I get an error, and then when I try to launch the phone, it goes into a bootloop as the guy shown on the picture. If anyone could help me, I would be in his or her debt forever. 🙂
