Your machid and hw_version variables are as-expected, so the image I gave you probably isn't going to work. You will need to get a serial port to find out what is going wrong.
Hi jmomo,
I've tried to flash your new nohwcheck firmware image using the TRENDnet Recovery Mode method
but the device still boots up with the TrendNET OEM firmware. Three repeated attempts produced the same result
Have you seen any difference in the fw_printenv output I provided?
Best regards.
Hi jmomo,
Once I get the USB/TTL module (it probably takes several weeks from China), I will provide you with the necessary console debug log.
Thank you for all your help.
Best regard.
You can usually get them locally (well, a seller from the same country, at least) for a reasonable markup (~5 EUR/ USD vs. ~1.20 EUR/ USD), but those will arrive within 2-3 working days at most. Ordering them directly from china makes a lot of sense if you're buying a number of them, but for a quantity of 1, I wouldn't quite have the patience to wait for the delivery.

Hi slh,
I had actually ordered them about a month ago from Ali. Unfortunately, I did not pay proper attention to the order at that time so I actually ordered only the USB/TTL cables instead of their combo of cables/modules :-). I corrected the order later so it would take more time for the modules to come.
Best regards.
Hi buddy thanks for your great work! I could calmly install as it is in the tutorial the first failure as it worked! . I have a problem installing "WireGuard" or "OpenVPN" or "MiniDLNA" I get this legend:
The installed version of package kernel is not compatible, require 4.14.171-1-0894164c… while 4.14.171-1-3579383f… is installed.
estoy ejecutando "/files/lede/TRENDnet_TEW-827DRU_20200301190427_OpenWRT_v19.07.2_luci/bin"
what do you recommend to do? . I'm a noob in this world of openwrt! 
It sounds like there is an unmet kernel or kernel-module requirement, but that should not happen.
I need to know exactly how you are trying to install those packages. Are you following a how-to document or someone's forum post? Are you using the command line or the luci web interface?
I enter the address "https://192.168.1.1/cgi-bin/luci/admin/system/opkg" through the luci web interface, look for the package or program in "Filter:" and then by pressing install .. me It displays a list of packages or additional programs needed, giving me an item "INCOMPATIBLE VERSION". I don't know what happens if you install the package or program, avoiding that mention of incompatible

Hello! after installing the package anyway as you mentioned, minidlna is working anyway! . I also have the torrent client and a samba server installed. everything is working delivering better values than with the original firmware, even the wifi power is extremely higher in 5ghz AC network, it reaches points in my home that previously had no coverage, I hope the router does not suffer damage.
I only have one problem! The connected hard disk never turns off and I don't know why, nobody is requesting it, neither torrent nor minidlna nor samba. Formerly with original firmware it would shut down after a period of time only. It is configured in the firmware of my Seagate 2Tb expansion hard disk that after 15 minutes it turns off, but Openwrt reads it every few seconds unnecessarily because I see its light blink. Do you have any suggestion ? thanks for the hard work to run Openwrt
I can't help you with that one. I suggest you make a new post in the main help forum about it. You might be able to use a tool like "lsof" to find out what is using the disk.
Good luck

Mister Jmomo! I was able to investigate what is happening from your command. I found a solution. I leave the link maybe someone needs it.

Trendnet is selling TEW-827DRU v2.0R recertified.

This appears to be a Mediatek based version that would be significantly castrated.

Hi jmomo,
I've finally gotten the actual TEW-827DRU recovery console log when unsuccessfully attempting the method "uboot http Recovery Loader". It looks like the LEDE script failed to recognize the NAND FLASH in my TEW-827DRU (and those of some of the other users as I had previously mentioned.)

FYI,
Using the method "Console uboot tftp", I was able to successfully flash my TEW-827DRU with your 19.07.2 firmware.
However, the method "uboot http Recovery Loader" failed 100% on my TEW-827DRU with the aforementioned NAND flash error.
Best regards.
Hope you will see the message notification...
Here's the important part from your log:
LEDE TEW-827DRU script START.
Flashing the UBI image...
Removing MTD device #0 (nand0) with use count 1
Failed to set ipq_nand: Quitting.
resetting ...
It's failing on the ipq_nand command. This command is built into uboot and it prepares the SLC NAND flash for writing, which means assembling the UBI.
The strange thing is that the tftp method also runs the same script which calls ipq_nand.
I'll think about this for awhile. I might ask you to dump some of your partitions and upload them to me for analysis.
Hi jmomo,
I did some other tests and found that the "uboot http Recovery Loader" method also failed with the same "ipq_nand" error when using Trendnet OEM firmware images, so there was nothing wrong with your OpenWrt images. Nevertheless, the "Console uboot tftp" method always works for both your OpenWrt images and Trendnet OEM images.
The problem may be either the crappy Trendnet uboot http Recovery Loader (and its recovery GUI's fake upgrade success message) or some timing issue when invoking the command. The script may need to add some additional delay and/or attempt the command several times in a loop.
If you don't think neither of these workarounds may work, please add a note to your OEM http upgrade tool section about this possible failure on some TEW-827DRU routers, and indicate that users will need to use the "Console uboot tftp" method in such cases.
Best regards.
Thanks for confirming that the OEM firmware install also fails. I was looking at the OEM image FIT script yesterday and suspected it would also fail because it has a similar ipq_nand command string which exits on error.
I think this might be something that can be worked around, or at least I can figure out why it's happening.
The ipq_nand command in uboot prepares the NAND by mounting the UBI. This command only needs to get run once, and if it is run twice, it throws an error.
Normally the recovery loader should not be running ipq_nand, but it's obvious that sometimes it is.
I looked in my old dev logs and found at least one instance where this happened to me too, so I might be able to reproduce it.
For me, it only happened to me once or twice out of a hundred or more recovery loader boots, but for you it's happening every time. That strongly implies an environmental issue.
It might be caused by the reset button not being held down at the right time, for long enough, too late, or something similar.
We have the source code for the recovery loader, so I'll go take a look at it later. It's probably a race or something stupid.
It may be a few days before I get back to this. I'm a little busy this week.
Interestingly, I had no problem reproducing this issue. In fact, I can't get it to stop! WTF.
I tested the recovery loader as recently as a month ago when someone else had asked about a similar problem and I tested re-installing the OEM firmware and then re-installing OpenWRT.
I wonder what has changed.... quite the mystery.
