In SP Flash Tool, Error 1042 (often appearing as BROM ERROR: S_TIMEOUT) indicates a communication failure between the software and the device's Boot ROM (BROM) or Download Agent (DA). When paired with "Verified Boot," it typically means the device has security protections that are blocking the flashing process. Core Causes
Timeout: The PC sent a command but didn't receive a response within the expected window.
DA Mismatch: The Download Agent (MTK_AllInOne_DA.bin) does not support the secure boot configuration of your specific phone.
Security Lock: "Verified Boot is enabled" means the device requires a signed firmware or a specialized "Auth File" to allow flashing. Verified Solutions 1. Adjust Connection Settings sp+flash+tool+error+1042+verified
Change Download Speed: In the SP Flash Tool menu, navigate to Options > Option > Connection. Change the speed from "High Speed" to "Full Speed".
Battery Mode: Go to Options > Option > Connection > Battery and set it to "with battery" (or ensure the phone is connected with a charged battery inside). 2. Bypass Verified Boot
Use a Custom DA/Auth File: If your device has secure boot, you must manually select a custom Download Agent (.bin) or Authentication File (.auth) provided by your phone's manufacturer or a reputable developer community like Hovatek. In SP Flash Tool, Error 1042 (often appearing

Solution C: Verify Scatter File Version
If you are flashing a Stock ROM, ensure you have the exact version for your specific device model number. Even phones with the same name (e.g., "Tecno K7") can have different hardware versions (e.g., H718 vs H719).
Tecno, Infinix, Itel (Android 12-14)
These are the most common culprits. You must use auth_sv5.auth. Without it, Error 1042 is guaranteed. Also, ensure you are using the "Secro" DA that comes with their official firmware. Tecno, Infinix, Itel (Android 12-14) These are the
Frequently Asked Questions (FAQ)
Q: Does unlocking the bootloader fix Error 1042 automatically? A: No. Unlocking the bootloader is necessary but not sufficient. Verified boot is separate from the bootloader lock. You must either flash a signed image or disable verified boot via fastboot commands.
Q: Can I get the Auth file from the manufacturer? A: Typically no. Auth files are leaked by OEM service centers or extracted from factory firmware. Search forums like XDA, 4pda, or Hovatek.
Q: What if my phone is completely dead (no display, no vibration) after Error 1042? A: Don’t panic. This is a "preloader loop." Use Method 4 (MTK Bypass Tool) or Method 9 (test point). Your phone is likely still in BROM mode.
Q: Does this error occur on Qualcomm devices?
A: No. Error 1042 is specific to MediaTek processors in SP Flash Tool. For Qualcomm, similar errors are Sahara or Firehose errors.
