Vivo Y71 model1801 (Philippines, 2018): which firmware and chipset? Forgotten screen
Vivo Y71 model1801 (Philippines, 2018): which firmware and chipset? Forgotten screen
19-10-2026, 06:08 AM
Hi, I'm the original owner of a vivo Y71, box label model "vivo 1801" (Philippines version, made April 2018). I forgot the screen lock, no account is linked, and the service center says they no longer have the unlock software. I don't mind losing data and want to reflash stock firmware myself.
Questions:
1. Is model 1801 the same as PD1731F in firmware lists?
2. Which chipset does the 1801 use: MSM8917, MSM8937, or MSM8953?
3. Which firmware package and tool (QFIL or QPST) should I use? Is the "Philippines" PD1731F 1.10.1 package the right one?
4. Does this phone need test points to enter EDL (9008) mode? If so, does anyone have a photo of where they are on this board?
Thanks for any help.
