SM-G920A cannot flash stock, repair modem

[Tom Book]

I receive phone unknown baseband, null/null IMEI. I know the IMEI and baseband because ROM is 5.0.2 and I have it printed on the phone box. I attempt repair with Octoplus, imei remains null/null. Baseband unknown. I try to flash stock with Odin. G920AUCU1AOCE is PDA from Octoplus output, but flash never starts. Flash stops with NAND WRITE START. Please help.

phone no longer boots

[Tom Book]

I try to post output but GSM Forum prevents me from sending PM or posting it

Firmware write failed, BOOTLOADER, PARAM, CM write successfully

BOOT fails

File used is g920aucu1aoce_g920aatt1aoce_att_android_5.0.2 DOT OCT

I am in blue screen that says update error, but it appears to be DOWNLOAD MODE because I can attempt reflash

I go into Advanced Mode to disable Hidden but there is no hidden

[Tom Book]

RECOVERY also fails

Odin flash stops at NAND START.

I am not asking of support of ODIN, Octoplus is not even connecting to write EFS or flash recovery and I cannot provide logs because of GSM Forum restrictions. I was temp banned for a day trying to send PM's. I can only post until logs are sent.

Please, upload log files to some file share and post here link or send us link into PM.

I do not have Skype because of MSN. I have tried to contact via AIM and get:

I will try to flash software backup first, then update Octoplus on this computer before attempt again. Now that I am at 10 posts I can post logs

You say to flash with different firmwares, but I do not understand since there is no root for 6.0.1. Asking to update to 6.0.1. with baseband, HW modem unknown and IMEI null/null is asking to brick the phone, because I cannot root the phone to repair IMEI

moreover, you have not answered my question about IMEI. on qualcomm device, IMEI is read in the Read info output. But when i Read Info on Exynos, IMEI is listed as XXXXX- and not in the output, even though this is a new, unrooted phone

is because of lock?? both phone is lock and I intended to unlock, but wanted to repair null/null first.

there is baseband but IMEI is 000000000000000

when I go to write IMEI it is XXXXXXXXXXXXXX|X

this is how phone was when I receive it. no IMEI in output, different from Qualcomm which lists IMEI in output

Galaxy S6 marshmallow has the same appeareance with XXXXXXXXXXXXXX|X
