Hi to all, I have a problem on my N9 and im loosing ideas on how to fix it. so this is what happened,

I have a n9 64GB with product code 059J232. When update started rolling out for other brands last feb 28, I got excited about the update and checked on my phone if I already can get one but unfortunately, I have no updates to download yet. So in excitement, I downloaded PR1.2 of north europe (059J187). While waiting for my download to finish, I cleared my device (settings>reset>clear device). This time, I think something was wrong because it took longer than the usual, and my phone is just on the standby screen, and when I press the lock button it just displays nokia (just like when you boot the phone) and when I press it again it just goes to standby screen again.

So what I did is just reflashed it with PR1.1 of 059J232. It is the original image for my brand, and it is the image I use to flash before (and it works, I have reflashed it many times) but now, I got an error. What I noticed is the cmt-mcusw cant finish it. it finishes the writing state, but when it changes to finishing, it just gets stuck on 0%.

then after flashing, of course ill get an error saying:
ERROR: SU_GET_UPDATE_STATUS_REQ terminated with error code : Unknown error
Fetching error list:
bb5_rdc_cert_read failed

[Pipe 7] Finishing in error state with status 1

error failed to flash images.


so thats the error I got, but the phone can boot it self normally, but noticeable it has files missing. For example is when I go to settings then about product, it freezes there and cant display the info's. Also, it says There's a problem with your SIM. Which makes this unusable for me.
Iknow that its not my sim because I tried it with other phones. And when I go to settings>mobile network, it says no mobile network settings or something like that.

then I tried to install the north europe 64GB black PR1.2 which I downloaded, hoping to just fix my problem. The flash finishes, saying in the end update SW release success.

But when I boot the phone, it just displays WARNING: You have modified the device software, leaving the warranty permanently void etc etc. I dont know why it showed this, so I just reflashed with the same image. But still with the same problem.

I am so frustrated at this point, it took me a day to do this things and got nothing. So I tried to reflash with PR1.1 my own variant, and I still get the same error with flashing with PR1.1 before BUT not the downgrade not allowed something, then when I boot my phone it starts, shows the tour, but still same problem (no mobile network).

So at this point, I just thought of having OTA. So at first, it was okay, downloading the update. But when the DL'ing finished, and started with updating, it is just stuck at 0%. my phone is already hot but still no progress.

At this point, PR1.2 for my own variant appeared on navifirm. So again I downloaded it again, flashed, including EMMC. The flashing was successful, just like when I tried the North Europe variant. But again, when I start the phone, same warning shows.

So I am VERY hopeless this time. I have no idea what more to do to fix this. I tried flashing with pr1.1 again and strangely, when it checks my sw release, (not the software im going to upgrade to) it still shows 20.2011 (PR1.1) even when flashing with PR1.2 said was successful.

I also thought my pr1.1 file got corrupted so I redownloaded but still the same issue. So anyone has any idea?

PS: To add, when in pr1.1, together with the mobile network error is the sync and connect. because I also tried to update using NSU. but it wont detect my phone. I know that it is on sync and connect because even NSS cannot detect my device.
