JHT Posted July 22, 2023 Share Posted July 22, 2023 Hi, I wanted to upgrade my Wifi pineapple MK5.8 and I used a wrong NANO firmware. At first, I use recovery method form this link but I download the latest NANO firmware upgrade and insert that. After I upgrade a while, I recognized I used the wrong NANO firmware, which has to be TETRA firmware and I tried to access 192.168.1.1 but it said the index could not be found, that means I cannot do anything now. The UART and ETH can be connected normally. I can access uboot with Putty via UART and I can change the ETH ip to upload via tftp, how can I recovery the bricked wifi pineapple TETRA MK5.8 via UART? Big thanks in advanced! Quote Link to comment Share on other sites More sharing options...

Just want to be sure you have actually tried that. I.e. holding the reset button and apply power and hold the button for 10 seconds followed by accessing the Tetra using the Micro USB ETH port (as described in the link in your post).

JHT Posted July 23, 2023 Author Share Posted July 23, 2023 Yeah I tried the firmware recovery procedure from that link to first upgrade the firmware, but then I realized I chose NANO firmware instead of TETRA, I saw the yellow LED just stay solid so I removed all the power source. After that, I tried that procedure again but it said the index file could not be found and so that I cannot upgrade firmware with that way. I then tried to do recovery via UART and found this youtube link so I tried to do that but no succeeded and seems like something broke the UART connection too, is it because of command `erase`? I tried to find the document for u-boot command but those command explanation made me confuse. In case if the command `erase` the NAND chip, how can I recover that, by inserting u-boot image via a special device to NAND chip or send it back to the factory and how to do that?

dark_pyrro Posted July 23, 2023 Share Posted July 23, 2023 Well, there's no valid factory to send it back to. The Tetra has been end of life for years now and has also reached end of support status. Even if it was supported and still sold, it wouldn't be the correct way to send it to the factory anyway. No idea if that YouTube video is valid for the Tetra. The only OpenWrt Hak5 device that I've seen being "reset" using serial is the Signal Owl. Don't know at all if that procedure is applicable to the Tetra. https://forums.hak5.org/topic/49420-recovery-reset/?do=findComment&comment=325670 1 Quote Link to comment Share on other sites More sharing options...
