Hello Raspberry Pi users,
My Raspberry Pi 3 B+ adventure lasted 30 minutes and now it won't boot at all. Any suggestion on what to do next? I have read "STICKY: Is your Pi not booting? (The Boot Problems Sticky)" multiple times and attempted the suggestions it contains, but nothing seems to help.

Raspbian Stetch Lite 2018-06-27 from https://downloads.raspberrypi.org/raspbian_lite_latest
What happened in the beginning:
1. On Windows 8.1, I used SD Formatter to overwrite format a brand new Samsung Pro 16GB microSDHC card.
2. I used WinRAR to extract the content of NOOBS directly to the root folder of the card.
3. I put the RPi 3B+ board in its case, hooked up the monitor and switched it to HDMI, inserted USB wireless dongle for KB & mouse to RPi, inserted microSDHC card and then applied power from the official power supply by inserting the microUSB power cord.
4. RPi started NOOB, successfully installed Raspbian Desktop, started Raspbian and then it went through its first-boot configuration wizard. I skipped updating Raspbian and connecting to Wi-Fi.
5. The first-boot configuration wizard requested a reboot, I let it reboot and my RPi 3B+ has not booted ever since.
6. Read troubleshooting guide at viewtopic.php?f=28&t=58151
Symptom: RPi 3B+ will not boot. Power LED is lit and Activity LED is dim. There are no regular or irregular flashes coming from the ACT LED. HDMI monitor reports no signal coming from RPi.
Troubleshooting steps already taken:
1. Removed power cord and microSDHC card. Let RPi rest. Re-inserted microSDHC card and power cord. No boot. Power LED is lit and Activity LED is dim. HDMI monitor reports no signal coming from RPi. (Multiple attempts.)
2. Verified with RapidCRC the SHA256 checksums of NOOBS_v2.8.2.zip and 2018-06-27-raspbian-stretch-lite.zip. Tested the contents of both zip files with WinRAR. All good.
3. Reflashed card and tried to reinstall OS: Removed the Samsung Pro microSDHC card from RPi, overwrite format it in Windows with SD Formatter, and extracted NOOBS to root folder of the card with WinRAR. Inserted card back into RPi 3B+, powered on. No boot. Power LED is lit and Activity LED is dim. No HDMI signal.
4. Substituted the Samsung Pro card with an used Sandisk Ultra card. Went through a full format and extraction of NOOBS with SD Formatter and WinRAR on the Sandisk Ultra. Tried this card in RPi. No boot. Power LED is lit and Activity LED is dim. No HDMI signal.
5. Overwrite format both the Samsung Pro and Sandisk Ultra cards with SD Formatter, write and read verify both cards with h2testw. The cards are fine.
6. Used Etcher to flash 2018-06-27-raspbian-stretch-lite.zip directly on to both the Samsung Pro and Sandisk Ultra cards. Etcher reported both images verified OK.
7. Tried each card in turn in the RPi. No boot. Power LED is lit and Activity LED is dim. No HDMI signal.
8. Extracted IMG from 2018-06-27-raspbian-stretch-lite.zip and used Win32DiskImager to flash both the Samsung Pro and Sandisk Ultra cards.
9. Tried each card in turn in the RPi. No boot. Power LED is lit and Activity LED is dim. No HDMI signal.
10. Suspected damaged pins on RPi's microSD card reader.
11. A forum post (viewtopic.php?t=217308#p1338686
) said the RPi 3B+ can boot from an 8GB or larger USB flash drive if I use Etcher to flash an image on to it. Used Etcher to flash 2018-06-27-raspbian-stretch-lite.zip directly on to Lexar JumpDrive 8GB. Etcher reported image verified OK.
12. With no microSDHC card in the RPi, I plugged in the Lexar USB drive to the RPi and applied power. No boot. Power LED is lit and Activity LED is dim. No HDMI signal. The light on the JumpDrive did not flash.
13. The pins on RPi's microSD card reader are probably OK. Somebody suggested taking the RPi board out of the case and to not fully insert the microSDHC cards. It did not change anything.
14. Used the official RPi power supply to charge a Sony portable powerbank. It is working.
15. Used the portable powerbank and a Belkin wall charger in lieu of the official RPi power supply and re-tested everything. These two devices can only output 2.1A maximum at 5.0V, but I didn't know what else I could do. No boot. Power LED is lit and Activity LED is dim. No HDMI signal.
I am out of ideas. Is there anything else I can try? Is there any RPi Expert in Sydney Australia willing to lend a hand?
Thanks for reading this post.
