Hi,

I have RB1000 with ROS v3.22 since I bought.
Yesterday, I successfully upgraded it to v4.5.
What I did was :
1. Upgraded the bootloader
2. Upload the .npk to "File"
3. Restart
4. Update the license key.
Everything ran smooth, even the soft ID had updated to 8 digits successfully.

But I saw there was 2 bad blocks.
I know that 2 bad blocks is OK, but yesterday was not a busy day and I had a lot of time in my office so I started to play with format NAND tried to remove the bad block.
What I did it.
1. Console the RB1000
2. Choose 'e' option to format NAND.
3. Connect using Netinstall.
4. Upload the ROS v4.5. (Netinstall)
5. Install the ROS (Netinstall)
6. Reboot

Then I checked the license, it was Level 0 and winbox said that the RB1000 does not have any license and I should buy new license.
I tried to update the license key but failed, it said something about "Wrong SOFT ID"
Did I do something wrong ?
Actually, before I did format nand I did not backup anything or wrote a note about the license. So I do not have any info about the prevous license .

Then I tried to downgrade the ROS.
I tried 3.30, 3.25 and 3.22 but the result was the same.

Then I downgrade to 3.10, and the license shown normal and it has level 6.
But since then, every time I tried to upgrade v3.25 or above, it will failed.

Then I brought the RB1000 to my supplier, they are well known mikrotik distributor and trainer in my country.
And I ask them to upgrade the RB1000, but they failed. Even they have all information about my device, but they still failed and end with the same result.
Then they suggest me to wait their boss coming from MUM till 10 March and they will ask their boss about my problem.

So rather than just wait their boss, I like to know your opinion about my problem.
Any suggestion will be appreciated.

Thank you

NAND format erases license information. you should not do that w/o support request

Hi Chupaka, thanks for your reply.
Would you please explain to me what do you mean with "support request"? Do I have to contact mikrotik first before I "format NAND"?

Actually, before I format NAND, I searched wiki and forum first to make sure that format nand is safe. At that time I could not found that format nand will erases the license.
But today I just found a thread that Normis said format nand will destroy the license

I wish I read that before

So the only way to upgrade is buy new license?

Or contact MT Support (support@mikrotik.com). They have all soft-ids and licence keys

yep, only Support can help

You guys right!!

Yesterday I contacted support using my account with attached suppout of my RB1000 with v4.5 installed and replied by them within 24 hours with the license key for v4.5.
And now my RB1000 working normally.

This is great. Mikrotik support is rock!! Good job guys

Lucky you - I tried contacting support with the same problem and received no response. This is the second time I've had no response before the time-out period (if at all) when requesting key support
