thank u so much for reply but i was select SC773X all sldr file on flash option and try but fail as same,
i was try to find flash file which on phone, unfortunately there is no where to find this version file
build number
A1000_S101_170511_TRUE_TH

if any one have this firmware pls give it then we can conect and try unlock this phone

[Brka]

Looks like that firmware have "Hard Lock" (Locked on firmware level).

Solution would be to backup existing firmware, nvm area, then
reflash with ROW firmware and see what will happen.


this is (a little cryptic) description from original ROM release info :

A1000_USR_S113_1705252051_SPRD7731_TRUE_TH

Applicable Country：Thailand/TH

1. To prevent being cracked, brush into illegal software will lead to the phone can not be used normally.
2. After the boot, increase the prompt ""Please ensure to install with Lenovo authorized firmware version. Unauthorized firmware version could damage your device"".
3. Change SIMLOCK requirements, SIM card 1 and SIM card 2 lock card program the same, white list: 52000 20, 52004, 52099 46000/46002/46007, shielding unlock function, when using non-custom card pop-up ""Phone is for Truemov H only"" , Close can continue to use other features of the phone, can not use voice, text messaging and data services.

[fazargsm]
