Please help me, im newbie, i installed Open wrt on my re200 v1 a year ago, and can't find detailed instructons how to rewert back to original firmware, can someone tell me detailed step by step how to do that, and what software i need to do that?
How to modifiy/prepade original bin file, in which program, and how
"Download an OEM firmware from TP-Link and prepare it as follows (we need to strip the first 0x200 bytes TP-Link header and the next 0x20000 bytes U-Boot):
dd if=re200v1_eu_3_14_2_up_boot(160329).bin of=re200v1_tftp.bin bs=1 skip=131584
Transfer this file to your RE200 running OpenWrt:
scp -O re200v1_tftp.bin root@192.168.1.1:/tmp
Install it by forcing a sysupgrade:
sysupgrade -F -n /tmp/re200v1_tftp.bin
Flashing this relatively big file takes some time, so be patient. Afterwards, you should be back to stock."
And then how to upload it, with putty or i'm wrong? Sorry i'm not programmer
dd is a program
https://man7.org/linux/man-pages/man1/dd.1.html
If there's enough space on your routers /tmp, you could copy the firmware file to the router and run the commands on there.
scp is a program to copy files.

These are all Linux terminal commands. dd and scp are to be run on your computer while sysupgrade needs to be exexuted on the RE200 (e.g. via ssh).
