Need Heelp.
the router turned on for a long time and i found out in log this

Thu, February 29, 15:23:44 2024 core.warning the kernel: [ 1.182507] GPT: The main header considers Alt. the title is not at the end of the disc.

I really shouldn’t have searched the Internet for advice and understood what it was. and I found such commands

root@Brume2:~# sgdisk --backup-table /dev/mmcblk0
root@Brume2:~# sgdisk --move-second-header /dev/mmcblk0

Warning! Secondary partition table overlaps the last partition by
33 blocks!
You will need to delete this partition or resize it in another utility.

oot@Brume2:~# parted -l

Error: Partition(s) 6 on /dev/mmcblk0 have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use.  As a result, the old partition(s) will remain in use.  You should reboot
now before making further changes.

after the reboot, the green (left lamp) light is constantly on. recovery via u boot is fine, but after the firmware is completed, it restarts and the green light is blinked 2 times and on constantly again, but there is no network.

What do you mean by it? Just CPU or many processes writing on the flash memory?
For me this sounds like the flash memory is done …

3

I wrote it wrong. not overloaded, but turned on for a long time
is it die? Or there is a chance?

4

is there an option in brume2 to flash via uart and will it help if the problem is due to the parted command? If so, how to do it correctly?

5

Can you email to support at glinet.biz and we’d like to get it back to investigate.

6

I sent this by email support@glinet.biz

7

Thank you. Now it is working :+1:

8

May you share the solution?

9

support sent me a gpt file

10

but every time the router boots, warning messages appear in the log, but I decided not to take any more risks with Parted

Fri Mar 8 18:12:39 2024 kern.warn kernel: [ 1.182372] GPT:Primary header thinks Alt. header is not at the end of the disk.

In this situation can you reflash the firmware in normal way?

12

If you give me a that file for me, please?

It is same issue I’ve already seen, but support team don’t solve the case,
just suggest a discount coupon and buy a new one.

Best regards.
