N8 after downgrade Write CMLA Key - Failed <<< SOLVED >>>

[Frenzy_2020]

Hi ATF team,

Got this N8 for user lock as I did not have the latest firmware I tried to downgrade it by erasing and then reflashing the older firmware

I followed the following Steps


1. Backup RPL - IMEI and LOCKS->IMEI->Backup RPL
2. Backup Full PM - PM/PP->Read Full PM and simlock data in IMEI tab
3. Full Erase Phone - Flashing->EraseFlash->Scan->Erase
4. Write Flash with lower version - Flashing->WriteFlash - ENO needed for supported models
5. Write Backup RPL - IMEI and LOCKS->IMEI->Write RPL
6. Authorize Phone - ATF Network->Login to account-> Authorize a BB5 NEW HASH Phone
7. Repair SD and Writing PM Backup - PM/PP->Stand Alone SX4->SX4 PM Authorization->Select PM Backup

However I get CMLa keys failed every time I try also tried repairing the keys via ATF network it does says fixed but and not sort out the problem, Now the phone stuck on three dots blinking

Hi friend

I've been reading your post here
http://forum.gsmhosting.com/vbb/f609...olved-1624011/

I did a downgrade on a Nokia 603 and I also have the same CMLA keys not found, how did you fix it?

I was able to install only 12 version of firmware which is Belle FP1 but If I try to put 11.030.0609 which is Belle Refresh the phone is stuck with the three dots loading.

How did you fix it?
