Audit13, thank for the reply. I'm sure I have 2017 MacBook Air, under post screenshot my System report.
I found that another users MBA 2017 have MBA71.... boot rom also.
Example: Macbook air 2017 SSD Compatibility with Samsung SSD

Here: Upgrading 2013/2014 Macbook Pro SSD to M.2 NVMe
User have older boot rom and NVME drive is available (omit the boot problem).

I don't have original drive so I can't update system and boot rom. Actually system is installed on external drive USB.
You are correct and I was wrong. I see that 7,1 in the bootroom is for an early 2015 and 2017 Air.

Just want to confirm that you are using the disk utility from a high Sierra or Mojave usb installer.

The hp ex920 uses the same controller as the Intel 760p and Adata sx8200 pro.
 
Yes, I tried. High Sierra, Mojave usb installer and Ubuntu live don't see drive. On PC I formated and created partition on drive, but no good results.

When I put an Intel 600p in my early 2015 13" air, I did not have to use Linux or my PC to create partitions or format the drive. I was able to erase and install High Sierra from a usb installer.

Have you tried removing and reinstalling the drive and adapter?

Is it possible that some of the pins on the adapter are making contact with the metal cover over the motherboard SSD connector?

Is the adapter from Sintech?
 
Have you tried removing and reinstalling the drive and adapter?
Yes, repeatedly.

The pins I covered kapton tape. Adapter I bought on Allegro - the bigger auction portal in Poland. It's look like Chenyang, but don't have any logo etc.

I can only assume the adapter isn't working, your MacBook Air doesn't like the adapter/drive combination, or the drive itself.

I have a sintech on order and will either use a Intel 760p, Adata sx8200 pro, or HP ex920 don't they use the same controller.
 
Hi, I received the package with new adapter. Success! I installed new copy of macOS and all work fine. Old adapter has a defect, I found it tomorrow. Thank Audit13 for your commitment and advice.

BTW, 960MB/s read and 1530MB/s write - is it not enough?

Congratulations of your success. Those speeds are much higher than my Intel 600p in an early 2015 Air and look great :)

After installing Mojave, did the bootrom change?

I tried the method of @denj with the new SSD inserted, but it did not fix my hibernation issue.
(Extracting MBP112.scap and MBP114.fd from latest Mojave Update and replacing the NVMe driver)
I got the MacBook11,3 Late 2013 15" btw

I went into recovery and ran
Code:
bless -mount / -firmware MBP112.scap --recovery --verbose

The installation seems to have succeeded (or not? see screen #1) and the "MBP112.scap" file also appears in the EFI Partition under /EFI/APPLE/FIRMWARE.
But under /EFI/APPLE/EXTENSIONS there is the old Firmware.scap file. (see screen #2)
Do I need to replace it maybe? And/Or rename MBP112.scap to Firmware.scap? Or do I need to run it from the original SSD (still got it). Or maybe upgrade another way.

The following commands
Code:
sudo /usr/libexec/FirmwareUpdateLauncher -p "/Tools"
sudo /usr/libexec/efiupdater -p "/Tools/EFIPayloads"
did not work as it said that there is no newer version available (see screen #3 and #4)

After I restarted I got freezing again after I hibernated and had to force restart. Any idea without the
CH341A? The SPI to J6100 adapter seems not to be available here in Europe. At least I could not find it.
As I use filevault for encryption I'd like to hibernate and destroy the filevault key for maximum security like I had it before

I updated Mojave 10.14 to 10.14.3 and boot rom didn't change.

Thanks for the reply.

On my early 2015 13", I removed the Intel 600p, installed an original Apple SSD, installed 10.14, and re-installed the 600p. This process had my Air running a 10.14 bootrom.

When I upgraded from 10.14 to 10.14.2 with the 600p in the Air, the bootrom got updated.

I haven't original Apple SSD so I can't try this solution. All work fine and I'm happy that it finished successfully. Only one issue that I noticed is huge power consumption in hibernate state. I saw solution for this, I will try it.

You mean when you close the lid?

Choose hibernate mode 25 which should help.
 
Hi guys.
I have a MBP mid 2014. I'm replace the stock SSD with ADATA 8200 + adapter (it's not important I think what adapter for SSD You use. I have 2 sintech and any Chinese and all work with same result for me. Connections between all of one are different, but works)

But Yes everybody knows that HIBERNATION mode doesn't work on this older macbooks (year 2013-2014).

On models from 2015 and newer if You change hibernatiom mode from stock 3 to 25 it's fine. I replace SSD in MBA 2017 with ADATA 8200 PRO and it's work great. I only change this hibernation settings to 25 and battery power drains is 1% per day. Im thinking its OK.

But what with older MACs?
I try really, really, to much setting, I browse half of internet for this issue. Test and test and repetly test the various settings, but without satisfactory battery power drain.

I find this video:

Why do Macbook Pro's Drain Battery While "Sleeping"?

... and its only one options what I find with good/relatively smal battery power draining. I have about 3-5% per day. It's much better than 20-50% before.
But I don't know what exactly this settings doing, but pc work fine.

If anybody have some other great option what to do, please let me know. Thanks.

you mean hibernation doesn't work in 2013-2014 models, unless you mod your bootrom with an 2015 NVME driver, right?

Hi. Yes it's a solution, but is riscy. You can brick Your mac.
use a Matt Card instead, is about 60-65€
and the EFI-ROM Converting board J6100 for an SPI programmer will cost you around 50€ so in that case a Matt card is a better solution and you don't have any risk

Can you elaborate a bit on this solution? Afaik it's only to unlock EFI/bypass firmware password. How can you use it for this usecase?

No, many people in this thread have succesfully used a Matt Card to load the mod rom with the nvme driver on late 2013-mid2014 models
You can flash It with the same procediment that the user ohnggni explains on Page 62

what does that exactly mean, because hibernate mode 3 works pretty fine on my macbook pro mid 2014.
Hibernate mode 25 is sometimes called deep sleep where the ram contents are written to the SSD and the MacBook powers off. There is no trickle charge required to keep ram contents from being lost.

then use mode 3 - problem solved.

With hibernate mode 25, there would be no battery drain because the MacBook actually powers off. With mode 3, there is battery drain and the amount of drain depends on the drive. Some people experience lots of overnight drain while others experience a few percent.

I think a simple solution for 2013 and 2014 MacBooks woulld be to use hibernate 3 and shutdown if the MacBook will not be used for a few hours.

i have it on mode 3 and overnight it loses 3%, which is pretty okay i guess.
