You can use Qfil to restore laf_a and laf_b from stock rom. After that you can get download mode.

Did you fix this problem?

Soft bricked shield tablet PLEASE HELP!

So I bought my shield tablet back in March, used it until about may I think. Was browsing the internet then it suddenly crashed and got stuck on the Nvidia boot screen. tried to reboot several times. Nothing. So I forgot about it and thought I would just google the reset option later when I had time. Now since June I have tried everything! From factory reset to fast boot and adb my pc won't even recognize my tablet. Also I never turned on usb dbugging cause I didn't even know what that was. I even gave it to the IT guys at work and they couldn't fix it. Now after reading everything there is to read on this problem and trying to fix it myself I'm stuck on the no command screen with the dead android robot. And now I hear there is a recall do to the battery, I can't even check what type I have. So if someone can please help me I would be much appreciative. Also this happened after updating to the latest OS.

Hello,
Did you use "Fastboot flash recovery.img" as your command line??
I believe it is "Fastboot flash recovery recovery.img"
If you were able to unlock bootloader you're on the right track.

Yes I used "fastboot flash recovery recovery.img" but every command after that keeps telling me "failed to write file"

TWRP (Team Win Recovery Project) is a custom recovery that you can flash on your device. You can flash it like the stock recovery over fastboot. With TWRP you can make full system backups, installing roms or other stuff, wipe partitions and more. Keep trying to install the drivers on your pc. Try to use another usb slot or boot your pc into test mode to install the driver. If you can still access the bootloader, you have really good chances to rescue your device.
Okay will try that. Thanks man.

I see what your doing wrong. You probably don't even have the recovery img to flash. That's why it's giving you a write error.
There is a tutorial in the general section, that should have all the files and links, etc etc that you'll need to flash TWRP/CWM recovery and root the device if you want

If your referring to the recovery images from Nvidia website I have dowloaded that, also the correct drivers. Maybe there is something else I'm missing?

First off, let me ask, what is your end result for the tablet?? Are you trying to just go a Complete stock tablet or are you trying to do anything custom (ex. Custom rom, recovery etc etc)
I'm assuming that since you unlocked your Bootloader, your trying to do something custom.

Those official nVidia recovery images come with smaller .img files such as recovery.img, system.img, etc. You'll need to flash those one by one ("fastboot flash recovery recovery.img", then run "fastboot flash system system.img", etc. etc.) or you can just run the flashall script that I think is included in the nVidia images.
Otherwise, if you want to flash TWRP, you'll need to download the TWRP recovery (you can rename it to "twrp-recovery.zip"). Then you'll need to "fastboot flash twrp-recovery.zip" in order to flash the twrp recovery to your tablet.

OK. Then the link I gave earlier should help flash stock software onto your tablet.
However, that guide is only to go back to factory "state" Operating System wise. It may not help with hardware. Once your flash everything correctly but device still doesn't boot, its probably not software related.

After you unlocked the device but before trying to flash anything else on the device, try putting the shield into Fastboot mode. At the bootloader, select fastboot using the volume buttons.

So i selected "fastboot protocol" it blipped for a second then brought me back to the bootloader. tried flashing again and once i reached the fastboot flash system system.img it said write failed again. did it not engage the "fastboot protocol"?
Bringing you back to the bootloader was expected behavior. The "write fail" is a mystery to me. Sorry, that is all that I can offer.

Stuck in fastboot

Solution to below problem found in this thread: https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424
------------------------------------------------------------------------------
So I tried to root my OnePlus 7 Pro, somehow managed to get it stuck in fastboot. No matter what I flash or do to reboot, it just boots back into fastboot.
Normally I'd just flash stock recovery / ROM found on OnePlus' website, but they haven't added anything for OnePlus 7 (Pro) yet.
Anyone got any clue about this?

TWRP: Once the flash has completed, Don't use the "Fastboot Reboot" Command Instead
Unplug Your phone then
turn it off
Manually boot it into recovery by keeping Power + Volume Down button pressed.

Does this MSM Tool also work for OnePlus?
To search just with your favorite Search-Engine for this tool is one thing, do you know the link to a trustworthy source?
By the way, I cannot lock my bootloader (just like the OP) and I would like to go back to stock. I found a Video, but it says I need Oxygen OS 4.0.2, if anybody knows where I can get that ?

Question How do I flash stock ROM with locked bootloader?

Hi guys,
so after I got my xiaomi with a global ROM and wanted to update and that is when I accidentally relocked the bootloader. The version of ROM was invalid apparently and wouldn't let me boot and now I'm stuck in fastboot mode.
My problem is as follows:
-can't enter recovery, stuck at fastboot no matter how many times I try and reboot
-adb not working since I didn't enable it
-bootloader locked (miflash says so and it can't unlock it since I didn't check 'oem unlock enable' and I cannot boot ROM so I can't enable it)
-fastboot flashing says 'not allowed in lock state'
-edl mode not available
I've seen tutorials where people opened their phones to force the phone into edl mode via the testing points but is that the only way`?
Any suggestions on how I could unbrick it?
Much appreciated
yes, it is the only way.

you can use this tool to flash the phone on fastboot mode
Xiaomi King Tool - Home.
xiaomikingtool.com
its cost you only 5 credit
Can you flash files by fastboot? if so, flash the global rom images one by one, then reboot

			
				
I know this is a late reply, but I was in a similar situation with my phone and here is how I dealt with it: You need to access EDL mode, it doesn't require disassembling the device like the other user here suggested.

Hello, My Poco X3 System destroyed itself while I was using it, it showed a glitch screen and turned off. Now I went to flash my mobile through Miflash but it showed the bootloader is locked and now I can't unlock it as the system itself is destroyed and can't do anything. So i wanted to know if i can flash my mobile with cmd as you said above flashing img files one by one or let me know if there is any method to flash my mobile or unlock the bootloader? Please me help bro
flashing is possible with modified firehose programmer (no auth factory loader) or with authorized xiaomi account. both solutions are paid service and cannot advertised here.
please -as always- read the thread you posted in. I can see useful information shared already. wait for other replies.

Hi, try to flash the .img files from the fastboot stock rom whit cdm in fastboot, one by one, some files will give error but skip that, then reboot the phone as normal, it should work.
example:
fastboot flash boot boot.img
fastboot flash cust cust.img
etc.

I had a Mi 9T and by mistake I installed a recovery that didn't correspond to it, the phone got bricked, and the only way to save it was like this, I searched and read everywhere but I couldn't find a solution, flashing the .img files was my idea, I didn't know if it would work but it did.

To install a recovery, the bootloader must be unlocked.

Stuck in FastBoot Mode

Hey all,
My OnePlus Nord is stuck in fastboot mode. I tried many different images to flash as recovery with `fastboot flash recovery image.img`; I tried the twrp recovery image by @mauronofrio and the ones on the official LineageOS webpage.
I've seen there some other threads to this problem, but none of the suggested ways seemed to work for me.
What can I do to completely reset the device and flash the original vendor image? Please give me detailed instructions to diagnose and fix the problem. Many thanks in advance!
