@tarask1n - I'm sure that reply must come from tier 1 minimum wage workers that do not care, sad to see. Yes, I agree, no need to send it in, confirmation that "other than your system" is affected is this thread (Thus we know for sure BIOS 205 is rubbish)
And we tested 205 fixed just like you did, it's broken BIOS, I don't know something wrong with BIOS not working well with ME FW, EC FW, or just the BIOS itself is broke, but clearly you are not alone and there is an issue with 205 BIOS

You can transfer your serial, UUID, MAC ID, windows keys, NVRAM and all that into the other BIOS, but due to moving NVRAM a lot of other edits would also need done (Setup, AMITSE, AMITSE/SetupData would all need swapped as well)
Best to stay on 203 and update it with stuff, if you don't know how to do that I can do it for you. I can also probably unlock all the hidden BIOS settings for you too, I've not looked at this BIOS for that, but it's my specialty so I'm sure I probably can on this model too.

Once enough people start reporting it to the low-level tech guys they'll have to pass it along to the BIOS team, then they will find and resolve the issue. Until then, nothing we can do except wait for 206 on this model or update 203 to be better than 205 anyway

@Lost_N_BIOS - thank you very much for your supporting words.
I've encountered some difficulty with restoring setup settings for 203 BIOS.
This is the link with dump flash after 205 BIOS update failure. nonwork_205_BIOS
It will be greate if you can help in restoring proper setup settings for 203 BIOS.
Thank you in advance.

@tarask1n - Sorry, I'm not quite sure I understand what you mean/need? Do you need fixed (proper model) 203 BIOS like I made for Techsavvydad?
If yes, please confirm the above linked dump is from your board after the first time you bricked board using 205 BIOS while on 203 before that (ie not other model BIOS, or not programmed in stock BIOSof any version then dumped etc)

@Lost_N_BIOS - Yes, you are exactly right. This linked dump is from my board after failed attempt to upgrade to 205 BIOS.

@tarask1n - Thanks for confirmation, Please give me images of the stickers inside your back casing (if any), sticker on the bottom outside of the case, and images of any and all stickers you see on the backside of the board, be sure to check on, around the memory slots, and under the memory too.
Your serial is removed, and your LAN MAC ID is missing too. See if you can find this in your router logs, it may not be on a sticker

Or, do you have any dump of the BIOS, using any method (even software), before you tried the 205 BIOS??

@Lost_N_BIOS - It has only one sticker on the back lid SN: EBN0CJIRR04A458 you could see it at offset 0x230000 in flash dump file. It doesn't have onboard LAN, only WiFi.
Unfortunately I don't have any flash backup before I've been stuck with 205 update.

@tarask1n - Yes, that one is there I saw before asking, but it's not the serial I was referring to. Great no onboard LAN, but that is different than Techsavvydad's system, how is this possible?
Well, nothing more I can do than, except give you this with your info padding moved over and updated fixed ME FW into 203 BIOS. I can update CPU microcodes too if you want?
This has your NVRAM from dump, may = brick. If so, let me know and I will put in stock 203 NVRAM only (Actually, just included both, try "WithNVRAM" first)
FD Unlocked in both, so you can use FPT to flash in windows now once you program either in (BIOS lock may need disabled via grub, but I left that as-is and I can show you how to disable later if needed)

@Lost_N_BIOS - About your comment that @Techsavvydad laptop had other configuration. It is not possible ASUS Q302 https://www.asus.com/us/Laptops/Q302/specifications/ doesn't have onboard LAN adapter.

Well I mainly meant that his MAC ID was stored in BIOS by default where yours is not, so I assumed it was onboard LAN. It was odd to see your info area not similar to his

@Lost_N_BIOS - thank you very much for provided BIOSes. Please update the microcode data to the latest.

@tarask1n - OK, I can do. Did you test already? If yes, which one worked OK? I will edit that one only
I'll do NVME mod too if you want?

@Lost_N_BIOS - thank you one more time for your help and support.
I've tested your NVRAM version before, it is completely matched with mine prepared for restore except FD write access six bytes. It is Ok. I found that my laptop has two additional hardware problems. The first one - the cable which connect HDD is damaged and the problem "Inaccessible boot device" was not in BIOS settings... The second - the CMOS battery is discharged (1,2 V) and the problem with Windows 10 sleep and reboot failures also was not in BIOS settings. So initially I had normally fixed BIOS but due to these problems I resoldered and reflashed BIOS chip three times

Did you have any information about discharged CMOS battery may lead to problem with BIOS update ? I mean that successful 205 update may be possible if battery was in normal condition.

@tarask1n - You are welcome!! If HDD cable is damaged, then you can't boot to any HDD attached to that cable. Are you sure it's damaged, or maybe just not inserting correctly?
Yes, Inaccessible boot device is not a BIOS setting this is letting you know you need to set main HDD to be first in the BIOS hard drive boot priority @ Boot >> Boot Option Priorities - but HDD may not show up if cable is damaged

Sorry, unsure what you mean about sleep/reboot problems. This may just be BIOS bug, if you can't sleep and resume system, or could be related to the CMOS battery (unsure, replace it and you will find out)
Yes, sometimes if CMOS battery is not good it may not update BIOS properly during a normal BIOS Update, and every time main power is lost BIOS would be reset to fail safe instead of optimal defaults. Replace the CMOS battery and that should go away (battery should be 1.3V or so)
1.2V may still be OK, but I would replace it soon. Does the clock time keep if you remove main power cable and main battery and wait 10-15 minutes, or BIOS and clock is reset after this? if reset, then you need to replace battery soon as you can.

No, BIOS 205 is broken, this is Asus issue we confirmed on page one, it's nothing to do with your machine at all.

So you want update microcodes in "WithNVRAM" BIOS I sent you? Order SOIC8 test clip with cable, so you don't have to always solder/desolder

@Lost_N_BIOS - Yes, please update microcodes in "WithNVRAM" BIOS you sent me.

Yes, HDD cable is damaged by the edge of HDD tray holder. I've ordered the new one from Aliexpress. CMOS battery should be 3.0 V, so mine is inoperable. If I disconnect AC power and battery connector the time and date reset to 01.01.2009. I replaced the battery yesterday and sleep mode and reboot working fine. I have SOIC8 test clip with cable but for that laptop model signal forming is not enough to get stable communication between the programmer and BIOS chip soldered on motherboard. It leads to data distortion during read / write operations.

I was sure that "no detected HDD" / "inaccessible boot device" and sleep / reboot failures in Windows are BIOS NVRAM incorrect problems. But it is not a valid case.

@tarask1n Duhhhh Ohh my!! Yes, sorry, for some reason I was thinking low voltage memory or something Yes, CMOS battery should be 3.3V new, less than 3V and it starts going bad.

For your SOIC8 / programmer issue, probably just wrong software version for your chip ID (or you need to leave main power cable and main battery installed, or remove both if you were doing with)
What is your BIOS chip ID?

Here is WithNVRAM + all microcodes updated to latest (which = 1 updated, other was already latest) + Fix FIT
ME FW I already updated to latest previously
