Multilaser RE027

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.
DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version (18.06 or later) onto it! See 4/32 warning for details.

1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.
This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

2) OpenWrt support for this device will end after 2019.
19.07 will be the last official build for 4/32 devices. After 19.07, no further OpenWrt images will be built for 4/32 devices. See OpenWrt on 4/32 devices what you can do now.

Also know as Multilaser RE039, this is a rebranded TP-Link TL-WR741ND v1 from Multilaser (brazilian vendor), and will only accept firmwares with Multilaser vendor ID bytes (in the file header).
Other compatible firmwares(TP-Link, OpenWRT, Gargoyle, DD-WRT) use different vendor IDs, or does not come with those bytes (which are needed for switching the stock firmware, otherwise you will get TP-Link error 18005).

Installation

Steps:

  1. Download this tool: Firmware_hardware_ID_modifier.exe - The tool is in Chinese, but it's really simple to use.
  2. Download a compatible TP-Link WR741ND v1 firmware. (TP-Link or 3rd party)
  3. Open the tool, choose firmware, and edit the values: (0x40-0x43) 07410001 [router model], and (0x44-0x47) change from 00000001 to 00280001 [vendor id]
  4. Some message will pop up. The firmware headers are now changed.
  5. Open your browser, and upgrade the firmware normally by the web GUI. (don't do this through wireless)
  6. Your router will then restart with the TP-Link / 3rd party firmware.

For the next firmware updates, you don't need to change vendor ID bytes again.

Everything can now be done like it was an original TL-WR741ND v1

* This can be applied to many other rebranded routers using the same hardware.
