If you own a Vivo Y1S (2015 edition)—often confused with the later Y1S (2020) model—and you are facing a dead device, a boot loop, a permanent hang on the logo, or the dreaded “100% TE Hot” error in your flashing tool, you have come to the right place. This comprehensive guide dives deep into the causes, solutions, and the exact flash file (firmware) needed to resurrect your device.
Note: The Vivo Y1S released in 2015 is powered by a Spreadtrum (Unisoc) SC7731 or similar chipset, unlike newer MediaTek variants. This guide is specifically for that older hardware.
| Error Message | Solution | |---------------|----------| | TE Hot 100% | Use battery disconnect method (Section 3.A) | | S_DL_GET_DRAM_SETTING_FAIL | Wrong flash file – redownload correct SC7731 firmware | | BROM ERROR: S_BROM_CMD_STARTCMD_FAIL | Driver issue – reinstall SPD drivers and use USB 2.0 port | | Checksum Mismatch | Corrupted PAC file – re-extract or download again | | Phone stays dead after flash | Dead battery – charge using a universal charger for 30 min before retry |
No. A hang on the logo requires firmware reflash via PC because factory reset from recovery won’t fix corrupted system files.
