My jetson nano developer kit 4gb is powered on. the green led is on. But it doesn’t desplay any thing on the screen using HDMI cable directly.
we start boot using the sdkmanager. After we select to download only OS, the download is completed. But it doesn’t complete the installation. it gives Failed to install.
We press repair button and go back to step1 but it gives the same error.

Dump the log, please.
Couldn’t understand
I have the same Issue with same board module Jetson nano 4GB Dev Kit ( P3450 )
- I use 64GB SDcard
- 5V - 2A from DC jack
- I try using force recovery mode to setting it up with SDK Manager but my host Ubuntu was 20 (Jetpack not supported only ubuntu 18.xxx)
- My flashing method was using Etcher tool to flashing the Jetson OS image
what I see in the HDMI connected screen : loop white board with nvidia big logo …
Then you need to follow above page to dump the boot log.
But no matter what situation, you may need ubuntu18.04 host in the end.
for now, unfortunately I don’t have the cable that used in the video for debugging
Do you suggest something else to do instead of logs?
Then you need to reflash your board with sdkmanager from another x86 ubuntu 18.04 host.
Ok, I’ll try that…
But I have question…
is that mean I cannot use custom Jetson Image ? and only re flashing and setting up using SDK managaer?
Nope, because you don’t dump log, what we can provide is limited.
If this is your first day using sdkmanager, then we can talk about custom image later because this is too early for that.
can I use ttl instead of this cable.
Yes, ttl cable is fine.
I have same problem with jetson nano developer kit 4GB.
I connected my jetson to my pc with windows plat form using TTL then with software serial program which is putty i got this log

Ok, please reflash your board with sdkmanager. Trying sdcard image does not help.
i installed sdkmanager on ubuntu 18.04 host then i tried to installing jetback just OS using it, downloading was done successfully but i faced an error of installation, then i tried to return to step 1 and repair but it didn’t work.
Then tell us what’s the error of installation.
There is a export logs button on your sdkmanager GUI. After you got flash failure, click it and attach the whole logs here.
i will provide you with these logs , but i want to make sure of something .
i am running ubuntu from a USB, is this a problem?
We don’t know. Your log will tell.
