[Xiaomi Mi A2 / 6X Questions & Answers] yisao:
Hi guys.. Thanks for this article!!!. It was very useful. I had my Mi A2 bricked, I was in QDLoader 9008 state, but I didn't need to disassemble the MI A2, I think as Lurensu my device was already in the QDLoader state. I reached this state trying to manually update to the November patch, then "fastboot" didn't flash the aboot_b image, yes sure; I didn't realize this until the reboot.

I had the error "Cannot receive hello packet" with fails trying to flash with MiFlash, but the solution finally, was to have pressed the Power button for various seconds then the device was again ready for flash, and finally this was flashed to the September patch. I had this image files from some tools for rooting and updating.

Thanks again!...

I'm pretty sure your problem is more simple than you think. Perhaps this is not the more adequate Thread, you need the windows drivers for Mi A2. This trouble is easily "googleable" :good:

Con la herramienta Mi Flash de Xiaomi lo puedes recuperar fácilmente, todo está en Google. En parte es tener el programa MiFlash y que te bajes una ROM OEM de este sitio, lo flashees y queda como nuevo; todo esto suponiendo que no tenga un daño peor, pero eso es raro

This guide has not been tested on Mate 20. It's fine on Mate 10 Pro Pie, but the big question is if that TWRP works or not. So someone with a Mate 20 would have to test that first. Don't proceed with this guide if you don't know how to restore stock recovery (I haven't seen any firmware for Mate 20 yet, except for a early test version released as BLAOVS on FF).

I downloaded the firmware but still getting error "kernel rev. check fail. device:1 binary:0

please another suggestion
[Samsung Galaxy S7 Edge Questions and Answers] smamow:
that error means that your device is in "binary 1", and you are trying to install a binary 0, so make sure you have the latest firmware.

Try unchecking "BL" in Odin and then flash.

this occurred to me after flashing LineageOS 15.1 and getting Root from stock Oreo 8.0.

Hi all,

I wanna use the S8 with Dex as low energy consuming entertainment system in my mobile home.

I tried the LG G5 and I'm nervous now ... Some unfixable problems ...

Some questions please

1. In Dex mode, goes the screen in standby?

With my LG G5 and MHL adapter the screen is staying black ... And never standby ... Waste of energy

2. If you let the phone in the station is the batterie staying full? With lte network, Wi-Fi hotspot and some usage like netflix.

My LG G5 is not staying full batterie ... Sometimes till 0%...

Greetings Chillcamper
[Samsung Galaxy S8 Questions and Answers] Nazty111:
Screen does go off on the phone while docked, and the phone charges as normal on the Dex, does not drain while using.
[Samsung Galaxy S8 Questions and Answers] Chillcamper:
Hey Nazty,

ok cool.

But I'm talking about the monitor.

I'm using an Asus 27 inch monitor.

The monitor is at the moment never going in standby.

It's just black and it is not stopping ... It will never go in standby. This it a huge energy drain :(

Is the connected monitor going in standby with the Dex station?

Would you check this please?

Greetings Markus
[Samsung Galaxy S8 Questions and Answers] Chillcamper:
Push, common please, it's important for me.

Is the connected monitor going in standby if you let everything connected and stop usage like at the pc?

I wanna let it permanent connected together.

Magisk 17.3-e1a65276 failed fastboot P3XL; error booting boot.img

Huge thanks for topJohnWu for his amazingly prompt Magisk update! I'm hopeful we'll see a working version of this quickly enter the Beta or Stable channels.

I've set my Magisk update channel to Custom, and successfully upgraded my P2XL to Magisk 17.3-e1a65276, but this is NOT yet working for my P3XL.

Canary Channel "How to"; (circa 2018-Oct)

Open Magisk Settings : UpdateChannel : Custom

paste the url (after removing spaces) ;

https://raw.githubusercontent.com/topjohnwu/magisk_files/master/canary_builds/canary.json

https :// raw.githubusercontent.com /topjohnwu /magisk_files /master /canary_builds /canary.json

Patched File sizes:

When patching "boot.img", I'm not seeing major discrepancy between input and output file sizes ; P2XL compared with P3XL. Both patched_boot.img file sizes are significantly smaller than original.

P2XL (2018.10.ppr2)

boot.img; 40 MB (41,943,040 bytes)

17.3 patched_boot.img; 24 MB (25,321,472 bytes)

P3XL (2018.07.pd1a)

boot.img; 64 MB (67,108,864 bytes)

17.3 patched_boot.img; 30 MB (30,953,472 bytes)

Failed ">fastboot flash boot patched_boot.img":

When attempting to reboot, following successful "flashboot boot patched_boot.img" command, the P3XL fails to load the patched_boot.img file, citing cause as "error booting boot.img" (See attached)

Recovery:

Issuing "fastboot flash boot boot.img", using the originally extracted factory boot.img file, restores expected boot behaviour, albeit without root.
[Google Pixel 3 XL Guides, News, & Discussion] Golf c:
I don't know if this will work. Did you try renaming the patched boot image to just boot.img and then fastboot it.

For those having trouble setting their Update Channel to Canary:

Canary Channel "How to"; (circa 2018-Oct)

Open Magisk Settings : UpdateChannel : Custom

paste the url (after removing spaces) ;

https://raw.githubusercontent.com/topjohnwu/magisk_files/master/canary_builds/canary.json

https :// raw.githubusercontent.com /topjohnwu /magisk_files /master /canary_builds /canary.json

maybe the attached images can overcome whatever wrinkles are happening with copy/paste?

As regards file names:

You can name your patched boot.img file whatever you like on your local PC file system. Syntax suggested by Magisk itself is "patched_boot.img" but you can clip that to just "boot.img" or rename the file to include the build and Magisk version, such as "20180720pda1_17.3_patched_boot.img". The local filename simply identifies the data source, to be transferred by fastboot, to the boot_a (or boot_b) partition.

I found it interesting that screenshots from the P3XL show little notchyness! They simply don't show status bar info where the notch is. Compare the two Magisk screenshots; P2XL with 17.3 installed, and P3XL without. The only hint of nachos is the absence of status stuff.

I am ****ed now, after I install the patch_boot.img, the wifi and sim is not working help, do you need to unlock the bootloader? which I did.

guys, I don't think it's working for me, at least the unlock version is not working. I had to re-lock the bootloader in order for the phone to function. I can't install magdisk, after I apply the patch_boot.img its not working.

I used the guide that you posted and flash it to both boot slot and then it's working. I think they need to update the original documents regarding a/b boot slots thanks for the help.
[Google Pixel 3 XL Guides, News, & Discussion] _EnemyWithin_:
Didn't work on my Pixel 3 XL. The patched_boot.img file is only 30MB. Is that correct? I attempted to boot the patched image and it didn't do anything. I flashed it (it went to boot_b) and it booted with stock boot image. I then flashed it to boot_a and it said invalid boot image (or something like that) and wouldn't boot. I flashed the stock boot image back to boot_a and now I'm running again with the stock image.

Any suggestions?

'fastboot boot patched_boot.img'

It says "booting" and I see my phone still in the fastboot mode, nothing really happening.

---------- Post added at 01:53 PM ---------- Previous post was at 01:45 PM ----------

Ok did both of those. Said on both

Sending 'boot_a' OKAY

Writing 'boot_a; OKAY

Finished. Total time: 1.547s

And the same for b

After doing the above, I type 'fastboot reboot', I hear the jingle sound like it's restarting, but nothing happens, still on the same screen

[Google Pixel 3 XL Guides, News, & Discussion] lollyjay:
Yes as I wrote originally you should flash stock boot.img to both slots and make sure that you can boot up

I think you may have a corrupted img

Will try now
[Google Pixel 3 XL Guides, News, & Discussion] lollyjay:
That's the correct one I think

Edit: have you received an OTA? If so then you will need another boot.img
[Google Pixel 3 XL Guides, News, & Discussion] Zorachus:
Ok...

I typed '.\fastboot flash boot crosshatch_boot.img'

that looked to have write good

I then typed '.\fastboot reboot' and it WORKED, I am back into the phone now :) Now what?

I did not receive any type of OTA. Are you talking about the October Security Patch ? Far as I know that's not even out yet for the Pixel 3, or at least my 3 XL never got it.
[Google Pixel 3 XL Guides, News, & Discussion] lollyjay:
