[Q] black screen no boot animation yet fastboot still works? - Nexus 7 (2013) Q&A

I have a Nexus 7 LTE tablet, I recently did a Paranoid android update and everything went smooth. I performed my nandroid backup as I normally would. At some point during the day, my screen went black. I tried rebooting the tablet, but the screen was still black. The device appears to boot fine. I have no boot screen, I cannot enter TWRP or any other boot loader. The notification indicator light blinks and I was able to access the device via adb.
I decided to flash the default nexus 7 firmware using the official google files - 4.4.2 (KOT49H) assuming this would work as per the directions I read in similar threads.
My issue continunes. I still have a black screen. I can no longer access ADB. Fastboot on the other hand works just fine.
Here is the output of my last flash attempt.

Even after a clean flash I still get a black screen and only fastboot is accessible.
What can I do to get rid of this black screen and get my tablet back in working condition?
Any help is appreciated.

I have the same issue, but I am stuck on google boot loop. I have tried going back to old factory roms, but still no good.
Have you tried using old factory roms? And were you able to go to recovery from bootloader? I can't even flashing stock recovery.

I have no bootloader available as the screen is black. I can only access fastboot. I tried flashing the original google supplied firmware as well with no luck.

As I look at the script it looks like that was a very fast flash. Did you check the MD5 to make sure the file was not corrupted? Because it does not even look like anything flashed.
Edit: At best, maybe, the system flashed but boot and recovery were done in a couple seconds. I'd check the MD5 or reflash the images.

For the 4.4.2 (KOT49H) Image (NOTE: The original flash that I showed the output for was for the later image 4.4.2_r2 (Verizon) (KVT49L)) In the past I have had more success with the KOT49H image and will continue testing using this image.

I agree that these write speeds seem a little too quick
Sidenote: Before I tried this last flash I was able to confirm that the digitizer is functional. The devices appeared to boot into the factory image (screen was still black) I was some how able to get the accessibility options enabled so that the devices would speak out my actions. I did not complete this tutorial. This leads me to believe there is some more bizarre underlying screen issue. Possibly a loose cable?

Hopefully something here can help.

Asus RMA was not horrible
I want to close out this thread with some answers about my experience.
I requested an RMA from Asus and sent my device to get checked out or repaired by them. I was fearful that they would notice that I had tampered with the device. I removed the backing to check the battery, unlocking the bootloader and flashing 3rd party ROMs etc.
I ended up re-locking the bootloader since I had fastboot access and tested my luck. I bubble wrapped the devices as Asus said they do not supply padding or any packing material for return of the product.
I was able to check the RMA status page and saw that my tablet arrived in TX at the repair site. They did not update the status page for 3 days with no indication of what caused the issue. Finally the status was changed from < Received > to < Repair Complete >. I had to contact support as they did not supply me with a tracking number. They gave me the tracking details and I got my tablet back yesterday. Asus did not use any of my bubble wrap and the tablet was free floating in a barely reinforced cardboard box.
No explanation was given as to the cause of the failure, I got back the exact same back cover as well as the screen. So either they changed some internal part or flashed some part of the device that I am unaware of.
Anyone else who has a similar issue and needs to get an RMA I would recommend the following.
1. If you still have access to fastboot relock the bootloader. You can check using
Code:
fastboot getvar all
1. Take photos of the device and all physical imperfections so you have some recourse if someone breaks the screen
2. Bubble wrap the device tightly to ensure no damage occurs on the way to the repair site.
3. Tracking & Insurance is a must. If you can prove the screen broke due to USPS or whoever then at least you can get a new tablet with the insurance money. Don't cheap out, get the $250 or $350 worth. The whole cost of shipping should be less than $10 and is worth the piece of mind.
Finally I just updated my tablet to 4.4.3 as it was returned with 4.4.2. Here is what a successful flash looks like, as well as how long each part takes to flash. Compared to the previous flash times one can see the difference.

My overall experience with the RMA process was great I did not have any of the nightmare problems that I read about on other forums.
Good luck to anyone going through this headache.

I had previously tried this with a few others such as MOB30D, MMB29V, MMB29Q, MMB29O with same results. Thoughts?
You are using an obsolete version of 'fastboot'. Get another one or try fastboot on Windows.

How can I check fastboot version? I just went through and downloaded what I thought was the latest version. Afterwords, I tried flashall again. I did 2 seconds further down into the install:

Stuck in bootloop, NRT doesn't help

My Nexus 5X was on 7.1.2 and rooted. But I wanted to go to 7.1.1 (for some compatibility).
So, I went on Google APIs and downloaded the 7.1.1 N4F26T, Mar 2017 build and together with Platform Tools I used "flash-all".
But... at a certain point, I get an error and it stopped.

So, I tried an older build, N4F26O.
This one worked, kind of, some errors in the process but it managed to finish the flashing.

Fixed the problem
So... until today, I always used the USB-C cable provided by Google/LG. I used it on the Thunderbolt 3 port on my laptop.
I ordered a new cable, a cheap one, USB-C to USB-A 2.0 and I tried again to flash the device from Soft Bricked with Nexus Root Toolkit and it worked!
This reply is for future people who may have this problem. Looks like Thunderbolt is not always the best move.

Trying to flash factory to my unlocked bootloader P2XL. Please help!

I'm trying to flash a factory image. I'm using the guide here: https://forum.xda-developers.com/pixel-2-xl/how-to/guide-unlock-flash-root-pixel-2-xl-t3702418 . I really have no idea what I'm doing wrong... the procedure is so simple, download the factory image and run flash-all.bat It goes, but I get errors. I searched but all I could find was a guy flashing the wrong image. I am using "taimen-opd1.170816.025-factory-907c4030" from https://developers.google.com/android/images. I was on 8.1.1 and want to go back due to multi-touch issues. Below is my log:

Well, it always happens this way - I create the thread and the issue is instantly fixed. I was using a usb2 hub hearing it was more stable. Remove the hub and flash and it works... FYI if anyone runs into the same issue.

Glad you got it fixed.
Adb & flashing rules:
1. Connect phone directly to computer. Don't use USB hub
2. Use the USB cable that came with phone, if possible
3. If it still fails, try a different cable or USB port
If adb recognizes the device, that means your adb environment is setup correctly and adb is working. If flashing still fails at this point, that means your cable or port is bad.

Running into a problem trying to go back to stock on Pixel 2 XL...

Hey all,
I recently got a Pixel 2 XL, and decided to unlock bootloader, and install Resurrection Remix. All went ok, until I got back a message stating, the stock images were incorrect. So, I decided to just go back to stock, and go back to it later. Well, I got the factory images from Google.
Im using Ubuntu 18.04. Within terminal I used ./flash-all.sh It kept coming back as, "Fastboot too old".
if ! grep -q dtbo.sig $(which fastboot); then
echo "fastboot too old"
exit 1
fi
fastboot flash bootloader bootloader-taimen-tmz12bb.img
fastboot reboot-bootloader
sleep 5
fastboot flash radio radio-taimen-g8998-00202-1802061358.img
fastboot reboot-bootloader
sleep 5
So, I removed the first bit of script, and it starts to download. But, it doesnt appear to download correctly. Still on RR when I restart? Heres the script that comes back:

I have never really run into this on a Google device. If anyone out there has any insight for me, id really appreciate it. Ill buy a beer to anyone who can help me out.
You could've just ignored that. It doesn't interfere with the device. Just reflash how you normally do then if you get that message again just flash the vendor image.

Well, after much research, and experimenting, I found that using the oldest image, from Sept 2017, fixed my issue. This whole time I was using the newest April image. Defiantly different with the a & b partition. That threw me off. But, all is well in Pixel land now.
