Q1: Can this tool write IMEI without a computer?
No—this is a Windows-only tool. For Android-only solutions, you need root and apps like "IMEI Changer" (less reliable).
Q2: Does writing IMEI void warranty?
Yes, modifying system-level identifiers voids warranty in most jurisdictions. However, restoring the original IMEI after a software flash might be considered a repair.
Q3: Can I generate a new IMEI randomly?
Technically yes, but the phone may fail network registration if the IMEI doesn’t match the correct TAC (Type Allocation Code) prefix. Always use the original.
Q4: The tool asks for a “DA” file – what is that?
Some V11 versions rely on a Download Agent (DA) file to talk to the CPU. If yours asks for one, use MTK_AllInOne_DA.bin (search online). The "Full" version usually includes it.
Q5: My anti-virus flags the tool as a virus. Why?
The tool writes to low-level memory sectors, which heuristic antivirus engines classify as "HackTool" or "Riskware." It’s a false positive if downloaded from a trusted source. Disable AV during use, then re-enable.
