Member: 121052 Status: Offline Sonork: 100.107126 Thanks Meter: 80,766 | @ maktel mobile, All of the Downgrade files available for download from the Free Sigma section at Boot-Loader.com Please notice that full firmware files is also required. Original full files can be downloaded from an Internet. Before performing any operation double check manual! NOTE! The downgrade operation is very risky! This feature is intended for advanced users only. Do the operation at your own risk. Best Regards GSMServer team Last edited by GSM_Support; 08-26-2020 at 06:28. |
