P3X [0800, 1500] Module Problem
Looks like he had V01.03.0020 and upgraded to V01.04.0010. During this upgrade, some modules were left intact. This includes:
[00013627][15 00][00] v1.1.2.0 -> v1.1.2.0 [00014004][08 00][00] v0.12.0.4 -> v0.12.0.4
This is where the issue started - he probably force-upgraded instead of force-downgrading.
Since then, the devices are "not detected":
[00028638][15 00][00] device not detected. [00041488][08 00][00] device not detected.
This means those two devices are still at firmware from V01.03.0020. To make them work, he needs to get the rest of the drone back to V01.03.0020 too. And I mean all components - they should all be at this version:
[03 05][00] v34.2.0.8 [03 06][00] v2.1.6.18 [04 00][00] v1.40.0.0 [09 00][00] v1.7.0.3 [11 00][00] v1.7.0.0 [12 00][00] v1.8.0.0 [12 01][00] v1.8.0.0 [12 02][00] v1.8.0.0 [12 03][00] v1.8.0.0 [15 00][00] v1.1.2.0 [17 00][00] v1.1.1.2 [17 01][00] v1.0.2.4 [19 00][00] v1.0.8.59 [01 00][00] v1.23.3419 [01 01][00] v1.23.3419 [08 00][00] v0.12.0.4
Now since he seem to have panicked and started trying every version he had, this will not be as simple as installing one downgrade. He should downgrade slowly, version by version. After he reaches V01.03.0020, he should post the log - we will compare his current versions with the list above to check which firmwares are not in its original state.
I think trying to up/downgrade the problematic modules will do nothing - the rest of the drone cannot communicate with them, so it cannot send them a new firmware. But I'm not 100% sure if it works this way.

So i will try downgrading my P3P with the m0800 and m1500 module problem one by one from the latest firmware v1.11.20 to v1.01.8. This drone was given to me. The last working firmware version is unknown. Currently i have flashed v1.11.20 to v1.09.6 with no success. Right now i am trying versions v1.08.8 all the way to v1.01.8 then after that upgrading to the latest v1.11.20. I am saving all logs for reference and any errors. If this is successful then we can confirm that this method works with the m0800, m1500 problem
01.10.0090 log attached is the hidden log and the result_ab. Failed. P3X_FW_RESULT_AB.txt P3X_FW_LOG_AB.txt
01.09.0060 log attached is the hidden log and the result_ab. Failed. P3X_FW_RESULT_AB.txt P3X_FW_LOG_AB.txt
01.08.0080 log attached is the hidden log and the result_ab. Failed. P3X_FW_LOG_AB.txt P3X_FW_RESULT_AB.txt
You've cited my post from over 4 years ago. It was speculative. Since then, we've got full understanding of the m0800/m1500, and how the modules work in general.
Downgrading may be required, but only in some rare cases. The module m0800 just needs to be fixed.
Read the project wiki for details.
Hmm, seems that the hyperlink is not working on the "By Chip Maker Method" (https://github.com/o-gs/dji-firmware-tools/wiki/Firmware-m0800#by-chip-maker-method) would you mind replacing it?
Oh seems that the processors.wiki.ti.com is now end-of-life. But i found an internet archive snapshot (https://web.archive.org/web/20200615014317/https://processors.wiki.ti.com/index.php/Writing_Kernel_Image_to_NAND_Flash)

"Downgrading may be required" Since it always fails to complete the firmware upgrade is there any chance of success by downgrading one by one to the oldest version using P3X_FW_DEBUG file then upgrading one by one without the P3X_FW_DEBUG?
Any suggestions and tips for flashing it without the serial port?
it always fails to complete the firmware upgrade
Stop thinking about firmware as one thing. It's a package.
Without serial port - don't know, I only used the serial port method.

Is there any guide that you can share?
Everything is on the wiki.
Alrighty. Connect my 3.3V TTL converter to service pads. which is 368_U0_RXP, 368_U0_TXP and GND for the P3X
I was really hoping for an easy way such as flashing it with a bin file but hopefully in the future. For now we can solely rely on the Serial Port method. I will report back here if the serial port flashing is successful.
Since this problem only come from the m0800 module i shouldn't need to touch/repair the m1500 module since if i fix the m0800 module it also fixes the m1500 right?
Do you have any recommended guides on how to disassemble the Gimbal Board of P3X?
