Thanks for digging that up. It seems the flasher I have is definitely bad, as the SPI communication is corrupted. I'm not going to spend any time on fixing this and will just wait on the new one that is arriving tomorrow.
Something like this might need to be done for adding XM25QH64C to OpenWrt:
But we still need to confirm whether this is the issue. If people with affected devices can provide full serial console output for OpenWrt 22.03.3 and any Snapshot builds we can check for presence/absence of lines like these:
[ 0.990803] spi-nor spi0.0: XM25QH64A (8192 Kbytes)
[ 1.000637] 4 fixed-partitions partitions found on MTD device spi0.0
If it sees none, thats a good indicator its not supported. @klojsch suggests this could be working in some snapshot builds with specific kernels, but we need to see those lines in the kernel dmesg console log to know for sure what chips it is seeing.
Here is this chip in uboot. Here are one, two patch attempts for upstream Linux, there seemed to be some ID conflicts so not sure where this ended up. I got no hits in a search in Linux kernel or OpenWrt sources on Github, but maybe it is in some version..
On my own WPA8631P v3 (which the kernel log tells me has a XM25QH64A flash chip), I upgraded to OEM firmware 3.0.1 Build 20220330 Rel.52768, then installed openwrt-22.03.3-ramips-mt7621-tplink_tl-wpa8631p-v3-squashfs-factory.bin and it runs OK. This rules out issues due to new uboot or new OpenWrt 22.03.3 version.
So it looks like the problem is due to lack of support in Linux/OpenWrt for XM25QH64C that is showing up in some newer devices.
To fix this, we'll have to submit a patch into OpenWrt. However from skimming the LKML threads above it sounds like there are some ID conflicts for this chip, so we'll have to get someone knowledgeable to review.
Until such a patch is merged and tested in 22.03-SNAPSHOT or the 22.03.4, I'll leave a banner on the wiki page discouraging installing OpenWrt on these devices, as it is not possible to tell which chip a device has without opening it up first, and these are huge pain to debrick without automatic TFTP recovery or an externally accessible serial console.
Here is a patch that might work, but it will need some testing and I don't have a device with that flash chip. If anyone can test it that would be great, (just have a flash programmer handy in case it breaks). (I'll upload some test build images later).
If some people can test and confirm here that it works OK, I will make a PR to get that merged into /master and /openwrt-22.03 so it will be included in the next release.
Update: Here is a build of the above patch applied to /openwrt-22.03.

Thanks! I can try the patch once I unbrick my device.
Is it possible to send me a backup copy for SOIC-8 flashing?
When I read back the current content of the (bricked) device, it's mostly 0xFFFF, is that normal? I'm using ch341a and flashrom 1.2-1094-g748575ab mentioned above
Could it be that the bootloader is stuck in a loop (when powered by the 3.3V of the flasher) and not allowing proper SPI access?
Message me with your email and I will send you a copy.
Yes, it can be a bit tricky to get a stable read/write on the flash. If you also connect to the serial console, try interrupting the boot so its idling at the uboot console, that will guarantee the flash is not being accessed while you are using the SPI flash.
Mine startet in a read-only mode after some trial and error. Connect it to a switch and plug it in with reset and LED buttons pressed. Hold them for 10 seconds and wait for the LAN connection.
You may need a few tries.
Connect with SSH to 192.168.1.1 and do a jffs2reset. Restart the thing and it might work again with default settings. If it keeps forgetting settings, flash a new image without keeping settings.
Edit: That does not help with the wrong flash obviously. Sorry, if that is the wrong thread, I was just happy to have mine resurrected.
Just in case people haven't seen it, here is a build of the patch on top of the openwrt-22.03 branch.
https://drive.google.com/drive/folders/1A0OO-DnMyVc6sHrr9GAS3HslYcQutBo6
It includes Factory, Sysupgrade and Initramfs images. For those who already installed OpenWrt 22.03 and bricked their devices, from the uboot console you should be able to boot the Initramfs image over TFTP into RAM, then check the dmesg logs to see what flash chip and partitions were detected (see log examples in this thread). If they show up OK, then post them here. We should expect to see the XM25QH64C be detected. If one person can confirm this and provide the kernel logs, I'll submit the patch.
At that point, AFAIK you can use sysupgrade to flash the sysupgrade file, then it should boot as normal. (There is no LuCi support, it wouldnt fit in this debug build). Then you can revert to stock using sysupgrade (see wiki, you can use the wpa8631pv3_eu-up-ver3-0-1-P1-20220330-rel52768-APPLC.sysupgrade from the directory above) or wait for 22.03.4.

Thank you very much for providing the firmware. To be honest, after having version 3.0.0 on my device, I didn't expect to have the new flash chip installed. Here is a log excerpt showing that OpenWRT is booting with it:

Great, as expected. Do you have that image installed to the device and booting OpenWrt on its own? (i.e. directly from flash, without uboot tftp initramfs loading). Can you post a full copy of your dmesg output here? I'll link that in the PR.
These lines look to be this issue here. I'll just mention them in the PR but it looks like we can ignore them here.
First, I updated from 3.0.0 to the 3.0.1 version you provided, and then I installed the factory image, all through the TP-Link web interface. My adapter is still unopened since serial access was not necessary.
Sure, here is the complete kernel log:

Thanks for providing the link, that puts my mind at ease about that.

Patch submitted. Thanks all in the thread for finding out the cause and testing.
A few days after this is merged, it should be possible to use the 22.03-SNAPSHOT images and they should be reasonably stable, but if you want to be sure your device will work and not be bricked, its better to wait until 22.03.4 is released and tested.

I installed openwrt successfully thanks to your work and the info in this forum. Now I have the problem that I can't install luci due to a lack of free space. What can I do to help that? Thanks in advance for any hints.
Those images I built above are just for testing this patch and aren't meant for general use.
What is your output from
dmesg | grep "spi0.0"
If it shows the line below, then you can install the current official 22.03.3 release:
# Safe for 22.03.*
spi-nor spi0.0: XM25QH64A (8192 Kbytes)
If it shows the line below, you should wait for this PR to be merged and 22.03.4 to be released. Installing any earlier version will brick your device. Building your own images can easily brick the device and the only way to recover is flashing the SPI flash directly, so as stated on the wiki its not recommended.
# Only safe for 22.03.4 when PR is merged
spi-nor spi0.0: XM25QH64C (8192 Kbytes)
So that means I could install the master right?
No, XM25QH64A means you can safely sysupgrade the existing official 22.03.3 release. Copy the file to your device somehow, then just do:
sysupgrade openwrt-22.03.3-ramips-mt7621-tplink_tl-wpa8631p-v3-squashfs-sysupgrade.bin
See the generic sysupgrade instructions for more information.
Do not use the -F force option, there is no need with OpenWrt sysupgrade files, and not using -F helps prevent accidentally flashing the wrong file which can brick this.
You are brilliant! Thank you so much!
If your problem is solved, please consider marking this topic as [Solved]. See How to mark a topic as [Solved] for a short how-to.
Thanks! 
That was for a side issue, the original thread issue of specific flash chip support is still open, pending PR merge and follow up testing, so we should keep the thread open until then.
Thanks for getting old threads closed though
