Don't forget to note actual information about the phone, like firmware version and so on. Doing the backup of the firmware is also a recommendation. | |

In most cases Testpoint has to be used to force the device to FACTORY mode You can use SOFTWARE TESTPOINT for low firmware and security versions. Last edited by Gsmserver; 06-11-2022 at 09:13. |

Member: 2836410 Status: Offline Thanks Meter: 97 | Downgraded via HiSuite Proxy 3.02 method, thanks. But please fix this poblem, because UFS models needs 7th file - .skf downgrade file, but nowhere such file- "STEP 5: Select lower fw version + downgrade file: Open HiSilicon tab and go to Flash bookmark Select DBA adapter port in the ports tab Select files for flashing: Important! You need to select 7 files for downgrading exactly in this order. FLASH FILE 1: PTABLE.APP from update_sd_base folder FLASH FILE 2: PTABLE.APP from update_sd_cust folder FLASH FILE 3: PTABLE.APP from update_sd_preload folder FLASH FILE 4: UPDATE.APP from update_sd_base folder FLASH FILE 5: UPDATE.APP from update_sd_cust folder FLASH FILE 6: UPDATE.APP from update_sd_preload folder FLASH FILE 7: Special downgrade file in *.skf format that fits to your actual model, phone's firmware version and customization version. We prepared it in step 3." |
