Technical Notes for Technicians

For optimal results with this new solution, technicians should be aware of several important technical considerations:

1) Button Combinations: Some devices require holding volume keys and power button until the "Reconnect Battery" prompt appears for stable EDL connection.

2) Device Detection: When an Oppo or OnePlus Qualcomm phone is connected, ChimeraTool automatically attempts identification. If this fails, holding both volume keys with the power button usually helps complete detection.

3) OppoDL Mode Handling: In cases where devices enter OppoDL Mode instead of EDL, technicians should:

Manually enter Recovery Mode
Select language
Tap multiple times on "Version" to access the hidden menu
Switch to Download (EDL) Mode from this menu

3) AntiRollback Protection: After firmware updates, some devices may stop entering EDL mode if the new version blocks older programmers. This is expected behavior on certain protection levels.

4) Android 15 Specifics: On OnePlus 13, the programmer only functions after the second boot, which technicians should factor into their workflow.

Market Impact and Industry Response

The GSM community has responded positively to this update, with many technicians noting that it addresses a long-standing need in the industry. While some feel the update doesn't fully match the hype given ChimeraTool's large user base of approximately two million, most acknowledge that it covers numerous real-world use cases, particularly in markets where Oppo and OnePlus Qualcomm devices are prevalent.

The ability to service devices with up to 10-month protection patches on several newer models has been particularly welcomed, as it eliminates the need for expensive JTAG or server-based solutions in many cases.

However, some widely used models such as Oppo A3 4G, A3x 4G, A5, and A5 Pro 4G still don't work on the month-10 patch. The community expects these to be addressed in future updates.

Advanced Features: Firmware Structure Handling

A significant technical advancement in this update is ChimeraTool's new capability to flash the updated Oppo/OnePlus firmware structure where the super partition is split into folders (metadata-style ROM). This feature:

Makes ChimeraTool one of only two tools (alongside AMT) with this capability

Greatly facilitates dumping and writing official flash files

Enables easier repairs for devices with this firmware format

Opens new possibilities for technicians who rely on dumps or JTAG-related methods

Conclusion

This ChimeraTool update represents a significant milestone in mobile servicing technology, particularly for technicians working with Oppo and OnePlus devices. By eliminating previous restrictions and expanding offline capabilities, it streamlines workflows and reduces dependency on server-based solutions.

As the update week continues with more features expected, this release already changes how service centers handle Oppo and OnePlus Qualcomm phones. The community-driven approach to expanding device support ensures that the tool will continue to evolve and address additional models in the coming weeks.
