My router is already flashed with OpenWrt can I redo your manipulation via UART to increase the storage space and the UBI version? Thank you I has heard 10 gb work can you confirm ? In version 25.12.3 or not ---

Btw, what happens when you flash initramfs.itb image in an OpenWrt stock firmware not U-boot layout? Will it just boot initramfs.itb? Or not do anything? ---

Dude btw, do I have to add restore to stock thing? I don't even know if that's even possible, never tried. I've tried some, but it seems rather difficult. I will pass on this, someone else should do that. ---

Ok revert to stock is also possible. This is a method I completely thought about and it worked. Didn't know if it was gonna work. TP-Link BE450 return to stock firmware: Now you need a special stock OpenWrt initramfs-kernel.bin file with kmod-mtd-rw compiled onto it. Here is one I compiled, drive link here:([https://drive.google.com/file/d/1eS\_rcjmPdCEhToFRZwiwW0PvJhyS-a8p/view?usp=sharing](https://drive.google.com/file/d/1eS_rcjmPdCEhToFRZwiwW0PvJhyS-a8p/view?usp=sharing)) So, just flash that initramfs-kernel.bin file, from the flash firmware button. You will then boot into that initramfs image. Then scp the required tp\_data.bin and boot.bin file to the router: ```plaintext scp -O tp_data.bin boot.bin root@192.168.1.1:/tmp insmod mtd-rw i_want_a_brick=1 mtd unlock boot mtd erase boot mtd write /tmp/boot.bin boot mtd erase ubi0 mtd erase ubi1 mtd erase userconfig mtd erase tp_data mtd write /tmp/tp_data.bin tp_data md5sum /tmp/tp_data.bin md5sum /dev/mtd5 ``` If both md5sum is equal, then you can just reboot. This step is very important without tp\_data.bin written right, you won't have ethernet. So, now you will be greeted with U-boot web recovery at 192.168.1.1, no static IP setting is needed for that. Just download TP-Link Archer BE450 stock firmware from the TP-Link Website and flash it. After it finishes, it will then ask you to reboot. Do that and you're back at stock firmware. ---
