So I have successfully installed LineageOS 17 gsi I downloaded here. => https://sourceforge.net/projects/andyyan-gsi/files/lineage-17.0/
flashed using these command and using stock vbmeta.img
fastboot --disable-verification flash vbmeta vbmeta.img
fastboot erase system
fastboot flash system name_of_your_gsi.img
fastboot oem reboot-recovery
it boots, kinda, it gets passed the boot animation but sticks. the only thing I can get to show is the power menu....it just has a black screen, any ideas?
I initially tried the first file lineage-17.0-20191117-UNOFFICIAL-treble_arm64_bvN.img.xz. the second doesn't install to the correct path

Try issuing this adb command during boot:
adb shell setprop debug.stagefright.ccodec 0
Thats what i did to make phh aosp gsi boot. I also flashed vbmeta with the --disable-verity and --disable-verification options.

Amazon Prime G4: Cannot install Nougat OTA, stuck at fastboot screen.

So I tried to install the nougat update, but my phone, which has been booting to fastboot ever since I messed around a little with it on RSD Lite, will not turn all the way off and the Nougat update fails. I have tried several times. My bootloader is locked and I am running completely stock with the ads. It shows up in the boot logs as "fastboot reason: utag bootmode configured as fastboot" . Anyway to fix this so I can upgrade to nougat? Thank you.
enter into fastboot mode and run this
Code:
mfastboot oem fb_mode_clear
mfastboot reboot

Thank you so much. That fixed the problem!
Where did you find the nougat update ,my xt1625 prime is bricked and I need that to try unbrick it .
If anyone else reads this; I had the issue and I just selected reboot recovery so I could manually tell the phone to apply the update. When it booted into recovery, it actually continued to install it automatically.
Does anyone have a backup of boot and recovery images for nougat xt1625 amazon?

Does this command have to be run from a specific directory?
'mfastboot' is not recognized as an internal or external command.
Thanks

You have to open the cmd in the folder where you have the fastboot and run fastboot or mfastboot depend or which version you r using .

Heard that there are two Oct updates, may I know if yours is the latest?
.15 is the second (latest) October update.
Guys, my phone is currently in august update (and I've unlocked and rooted the device with Magisk to enable camera api 2). What should I do to OTA successfully and safely? Thanks in advance!
Can't flash through miui flasher. Is it possible to flash this through recovery?
Are U tested?
I tested, it worked. Updated to Oct update thru fast boot.
There's a minor glitch - you have to remove the space of the folder name, otherwise windows cannot find correct folder location.

There is a space between "Android" and "8.1.0", the space must be removed or replaced by other characters.

I researched for such a long time on this, I'm exactly the same in your situation, rooted with magisk, camera2api substratum things like that on august patch.
Later on i figured myself a way to update without losing any data or wiping the phone which is :
1. download the full stock rom of august patch, it should be tgz files, extract it.
2. Make sure u got adb fastboot all the stuff installed on pc, and also mi a2 drivers.
3. On the phone, go to developer options and turn on usb debugging, guess u already done it since you rooted the phone.
4 now connect the phone to pc in fastboot mode.
5. After extract the tgz august stock rom, locate to folder "image".
6. Hold shift and right click open cmd or in my case open windows power shell.
7. Type fastboot devices to see if your phone is connected properly.
8. Paste these codes and hit enter.
9. After that the phone will be rebooted and after success booting go to settings > system update and start installing the ota without issues.
The codes :
fastboot flash bluetooth_a bluetooth.img
fastboot flash bluetooth_b bluetooth.img
fastboot flash devcfg_a devcfg.img
fastboot flash devcfg_b devcfg.img
fastboot flash dsp_a dsp.img
fastboot flash dsp_b dsp.img

fastboot flash splash splash.img
fastboot flash mdtpsecapp_a mdtpsecapp.img
fastboot flash mdtpsecapp_b mdtpsecapp.img
fastboot flash storsec storsec.mbn

Guess that every patches on mi a2 will work with thus method, haven't tested with any version other than august patch. Let me know if it's work !

Search google for mi a2 manually flash firmware.
The result that said "techdroider.com" will be the answer you looking for.
If you don't want to lose any data but still wanna update, remove line "fastboot....userdata.img"
No November update?

Stuck in Fastboot

Hi! Seems like there are many different reasons why a Mi A1 can be stuck in Fastboot. I found others having the same symptom but the proposed solutions didn’t work for me.
Not matter what I do, my A1 won’t leave Fastboot:
- holding power button reboots to Fastboot
- holding power and volume up button reboots to Fastboot
- holding power and volume down button reboots to Fastboot
- `fastboot boot twrp.bin` does nothing (`sending`, `booting`, nothing)
- `fastboot flash recovery twrp.bin` complains `partition table doesn’t exist`
- `fastboot flash boot twrp.bin` complains `partition table doesn’t exist`
I basically followed the installation guide to install Lineage OS, used CosmicDan’s TWRP though. That didn’t work. Found out that I had to partition the storage for Treble. Flashed TWRP. Used “tissot manager” to partition. No I am stuck in Fastboot.
Any clues what is happening here?
There is a mistake in syntax for the flash command.
After the fastboot command you have to provide the slot for flashing boot.img
example: fastboot flash boot_a boot.img
In order to not screw up your device, download stock boot.img and write to both A and B slots then execute the reboot command.
This should do it

not working
The command is [only for Windows] NOT FOR LINUX.
fastboot flash vbmeta vbmeta-sign.img --disable-verity --disable-verification
u entered it wrong ie fastboot --disable-verification --disable-verity flash vbmeta vbmeta.img
If it stuck at writing vbmeta then u need a custom signed vbmeta image
fastboot --disable-verification flash vbmeta vbmeta.img, not working for me though: fastboot flash vbmeta vbmeta.img worked for me on a Lenovo tablet. The only problem was that when I installed custom ROM I have had a bootloop on Lenovo logo twice and then booted on TWRP and not on custom ROM... Any ideas?

Bricked - Don't know what to do

I accidentally disconnected my OnePlus 8 Pro while running the MSM Tool to restore back to oxygenos from lineage. Now it is stuck in a loop where it says:
<Error!>
Upgrade download failed!
This is caused by download interruption. Recommend you use download tool try again.
You need to confirm if there is failure message on download tool or not when you see this error.
also please check if you disconnect usb or click stop button when the download is not finished yet.
You can press any key exit this message
I can boot into fastboot from this state, but I am unable to flash a recovery or use a fastboot rom.
The recovery just doesn't work when I try to boot into it, and the fastboot rom gets stuck at
"Flashing is not allowed for critical partitions"
and when I try running
fastboot flashing unlock_critical
it says something along the lines of 'device already unlocked'
I cannot boot into EDL mode either, and trying to do so doesn't work.
I feel as if I am out of options, and am very worried about my phone.
Please help!!!
I was able to successfully follow all the steps for a fastboot rom, but it still didn't work. This was through using fastboot boot on the lineageos recovery.

Use MSM Tool. Hold all buttons very until your device appears in msm tool. YOu can start before you connect it and it should work.

I understand that. When I do so, it just boots into fastboot. And when I tried to enter EDL through using 'fastboot boot' with a custom recovery, it did the same thing. Now I can't even use 'fastboot boot' anymore for some reason though.

Yeah, you need to wipe internal storage. In fastboot you can type
fastboot format userdata
fastboot format cache
Also, you can type

This happened to me. I tried downloading Qualcomm drivers and reinstalling them and moved my platform tools to root of C:\, among other things. I was using OEM red cable and had been having to flip it a certain way to get WARP charge, so in desperation, I switched to a non-OEM cable, C to C, and that got me back in EDL. Good luck.
