Any way to install modern OpenWrt after upgrade 4mb to 8mb?

Installing and Using OpenWrt
#1

Hi everyone!
Is there any possibility or way to install a "modern" build of OpenWrt on a TP-Link MR3420 V2.3 with 8mb of rom?
(updated by physically corrupt ROM and only find a W25Q64FVSSIG)

Even if it is build 19 or much higher ...

Model TP-Link TL-MR3420 v2
Firmware Version LEDE Reboot 17.01.6 r3979-2252731af4 / LuCI lede-17.01 branch (git-18.201.27126-7bf0367)
Kernel Version 4.4.153

Greetings! Have a nice day!

Yes, but you'll have to build from source with your modified flash partitioning (custom hardware, custom OpenWrt); keep in mind that 32 MB RAM is still a (very) limiting factor.

@slh beat me to the punch. The limited RAM is probably the bigger issue.

I was afraid that 32mb of RAM was insufficient... I had thought about Swap over USB (if it is possible to do it)

Possible, yes… but an utter nightmare for performance. These devices are simply past their prime and there are many reasons to replace them (flash, RAM, CPU performance, 802.11n).

i understand, i am aware that it is already obsolete... i just wanted to see if there was a way to give it a second chance like PrintServer/tinyNAS/OPVN or whatever...

If your device is not internet connected (such as print server) AND on a trusted network, you probably can safely use an older build such as LEDE 17.01 which will fit easily because security shouldn't be a significant risk there (although it is not a zero risk situation). You could then install a print server or whatever other local services you want and it should be fine. Keep your performance expectations very low, of course -- these things will be slow and limited.
