This update focuses on expanding support for Xiaomi and Vivo devices, particularly for bypassing account locks and system restrictions:

Auth Bypass (Disable DA/Auth) for newer secured MTK chipsets. Format/Factory Reset and Partition Manager access. Official Access & Downloads

Do you need help checking if your is supported for the MiCloud bypass or OTA disable feature?

Enhanced support for factory resetting and removing locks on Vivo devices using META mode. MTK Universal Functions: Read/Write Firmware and Scatter files. Reset FRP (Google Account Lock).

Be cautious of sites offering "Cracked" versions of v5.1. These often contain viruses or Trojans and may permanently damage (brick) the phone's bootloader during sensitive operations like MiCloud bypassing.

The most secure way to download is through the UMT Support Access Tool (official site) or the Ultimate Multi Tool support threads on GSM-Forum (Martview) , where the developers post official setup links.
