Hard reset on qn9080

By mistake I write after the m_data  ORIGIN = 0x04000400, LENGTH = 0x0001FC00.

change to LENGTH = 0x0001FD114 at qn9080 DK-v1.2.

I want to perform hard reset to configure the chip to manufacture parameters (with working bootloader).

 

I try to flash one of the sdk example programs and the ide write me an error:

 

'MCUXpresso RedlinkMulti Driver v10.0 (Jun 22 2017 23:31:55 - crt_emu_cm_redlink build 272)
Reconnected to existing redlink server (PID 4294967295)

Connecting to probe 1 core 0 (server PID unknown) gave 'Ee(36). Could not connect to core.'
Connecting to probe 1 core 0 (server PID unknown) gave 'Ee(36). Could not connect to core.'

Failed on connect: Ee(36). Could not connect to core.
No connection to chip's debug port
error closing down debug session - Em(02). MEM-AP is not selecte'

 

Can you help me?
