I messed around with my R6250 flashing back and forth from tomato back to Genie to dd-wrt, then bricked it. Finally, I managed to unbrick my router following the instructions at https://midnightme.com/2015/03/16/how-to-unbrick-or-fix-a-netgear-ac1450-router/, except for

- Step 12: I set up a ftpd server using ftpd64 on my laptop with IP address 192.168.1.5

- Step 13: I put the R6250-back-to-ofw.trx from Tomato to the router using the following commands
CFE> flash -noheader 192.168.1.5:R6250-back-to-ofw.trx nflash1.trx
CFE> go

(btw, for step 13 I tried many other firmwares like the Genie initial release 1.0.0.62, dd-wrt, open-wrt, advancedtomato, but none of these were accepted by the router.)

Now my R6250 was back to Genie and functioned well, but stuck with R6250-back-to-ofw from Tomato (= R6250-V1.0.1.84_1.0.78.) I have tried to update to many other Genie versions, or switched to dd-wrt, openwrt, tomato but failed.

Any advise is much appreciated.

Use the tftpd command at the CFE prompt. Other way is to put it into recovery mode via reset button.

the problem may be the R6250-back-to-ofw.trx firmware you used to restore originally, from memory you have to leave the user name blank on initial login then factory reset from gui.

personally i would connect serial back up, break boot to cfe and force an old version of stock firmware with tftp.

Many thanks for the advise.

Turned out the router's Board ID was incorrect. I followed this post https://www.myopenrouter.com/forum/changing-board-id-charter-edition-r6300v2-dd-wrt-firmware to correct the Board ID. Then everything is fine now.
