Guys, I'm newbie.

I have knowledge of electronics and this forum is the best on the internet in this matter.

I received a TP-link - C3150 v2(US), with the lights locked.

I tried to record the firmware externally and apparently the Bios is ok, but it doesn't boot.
I tried via UART and I only have the log below.

Could anyone help?

Could it really be software or could I have a hardware issue?

Thanks.

PS: sorry for the writing, I'm using a translator

The Supported Devices Wiki still lists the v1 as a WIP; does not list v2, and no download for either of them. So exactly how did you end up in this situation...?

https://wikidevi.wi-cat.ru/TP-LINK_Archer_C3150_v2.x

You might be able to use this method to recovery if serial recovery and/or TFTP recovery is not available:

Keep in mind, this router is *not* supported by DD-WRT, but we can try to help you de-brick and get back on stock firmware at the very least Cool

There was a power outage and he didn't turn on anymore ..

It was perfectly perfectly.

I've tried this link procedure, but I don't have any answer.

I also turned it on without the flash, and the leds were the same.

should there be any change?

I don't know exactly what you mean "without the flash", but if you tried a pin short de-brick method on this device, that is not advisable. You could likely save yourself a lot of headache unless you have a flash programmer and everything needed to restore the flash completely and just RMA it if you cannot get the CFE web recovery method to come up. I would probably opt to send it in for repair at this point if you can't recover it.

I turned it on without the eprom circuit, to check if the leds have any changes, but nothing.

when turning on the LEDs light up instantly.

I have the ch341a recorder, and I re-recorded a Dump file. I also re-recorded the firmware from the TP-link website, but no change in status.

Was it a true fullflash dump? A standard firmware file would probably not work. This device likely needs to be sent for repair; the power outage likely caused hardware damage.

Some tutorials I watched, there is a key combination to use TFTPD ( WIFI + RST).

Can you inform if there is something in this model?

I do not have this model in my posession; If it has that feature, you would press the WPS/RESET button or RESET button and power up the device with a TFTP server configured at a specific IP address and the device should automatically upload the file and flash it. I don't know of any method that uses two buttons, and the only other method I think uses the QSS button on older devices.

Sorry, I cannot offer anything more specific.

What I recorded was a true fullflash dump!

The equipment is not under warranty, unfortunately.

Thank you very much for the guidelines.

It will cost you a fee, but you should be able to return it for replacement (or possibly repair):

Unfortunately in Brazil, if you don't have the Fabrincante guarantee, it's not worth it.

Tp-link has a bad after-sales service in Brazil.

Thanks!!!
