I am attempting to put lineageos on my new Mi A1, following the installation guide here https://wiki.lineageos.org/devices/tissot/install
I have previously installed lineage on my old Moto G LTE and a Samsung Galaxy S4 and have not run into issues.
I have unlocked the bootloader and all that but I can't get twrp to boot.
I boot into fastboot with
Code:
adb reboot bootloader
that works fine, then I
Code:
fastboot boot twrp-3.2.2-0-tissot.img
This seems to have no effect, other than my phone 'disconnecting' from the PC.
I get the following terminal output
Code:
./fastboot boot .\twrp-3.2.2-0-tissot.img
Downloading 'boot.img' OKAY [ 0.682s]
booting OKAY [ 0.623s]
Finished. Total time: 1.336s
However nothing happens on the phone, it still just has the fastboot logo on it.
At this point if I manually reboot (long-press power) it will reboot into stock rom.
If I manually reboot into recovery (long-press power+volume up) it will reboot into stock recovery
I have ensured my sytem tools are up to date, and tried the previous version of twrp, and there is no change.
I WAS able to get twrp to boot using the "Mi A1 Tool" i found here https://forum.xda-developers.com/mi-a1/how-to/tool-xiaomi-mi-a1-tool-drivers-unlock-t3742857
However I was not able to install lineage due to an error.
I did not copy the exact output but it was something along the lines of
error 7, kInstallDeviceOpenError
After this attempt, I reflashed the stock rom using Xiaomi tools, and am back to the beginning.
The phone is fully up-to-date with stock updates, Android 8.1, July security update.
Once again went through the bootloader unlocking, and everything, but have arrived at the same result.
Anyone have any ideas?
any help would be greatly appreciated!
Thanks!
Hey, could you try this TWRP made for Oreo? https://www.androidfilehost.com/?fid=818070582850498337 (thread: https://forum.xda-developers.com/mi-a1/development/recovery-twrp-3-1-1-0-touch-recovery-t3688472)
I've also had some issues booting TWRP, but running
Code:
fastboot oem unlock
was enough to boot it successfully (
Code:
fastboot boot recovery-3.2.1-2-oreo.img
)
Thank you!

This recovery image worked great, AND installed lineage, thank you very much.
However, I am now unable to get gapps working.
I was pointed to this changelog here https://lineageos.org/Changelog-19/ by a user in the lineage subreddit.
I rebooted from twrp into the lineage recovery, chose Apply Update -> Apply from ADB
On my PC I run
Code:
./adb sideload .\MindTheGapps-8.1.0-arm64-20180610_024023
.zip
and after a pause I get the output
Code:
serving: '.\MindTheGapps-8.1.0-arm64-20180610_024023.zip' (~0%) adb: failed to read command: No error
and sometimes I get
Code:
serving: '.\MindTheGapps-8.1.0-arm64-20180610_024023.zip' (~0%) adb: failed to read command: Connection reset by peer
What happens on the phone has been a little different each time I have attempted this.
It either pops up on screen that it is unable to verify the file, install anyway?, doing so doesn't work.
OR it is hung up on a progress bar screen, with the following log output, or a slight variation of it
Code:
Stopping adbd...
Now send the package you want to apply to the device with "adb sideload <filename>"...
Finding update package...
Opening update package...
Verifying update package...
E: Signature verification failed
E:error: 21 Restarting dbd... Installation aborted.
After many attempts of this, reflashing lineage, and trying again, it did miraculously start doing the transfer at one point. It got to 47% then failed again.
Can't you just install from recovery?

Hey,
Install GApps also at TWRP. Signature verification is failing most probably because the Lineage Recovery should be accepting only Lineage-signed ZIP files.
You can install TWRP in your current boot image (so you don't need to boot TWRP everytime through fastboot) with this ZIP: https://www.androidfilehost.com/?fid=746010030569959456 (yet, you need to boot to TWRP through fastboot so you can flash it, but no need to boot it manually after installing it). Notice that after every system update you may need to install TWRP again (same for Magisk), as boot images get replaced.
Also, if sideload fails, you can just do a
Code:
adb push filename.zip /sdcard/
then install the ZIP directly from the "Install" section on TWRP.
Thanks!
Thanks a lot!
I found and was able to follow this guide
https://forum.xda-developers.com/mi-a1/how-to/lineageos-gapps-magisk-twrp-dolbyatmos-t3762939
instead of the one on the lineageOS website, and I am up and running.
Thank you very much for your time!
Can't boot to recovery or fastboot
I'm totally not getting the problem, i am having network issues on my Mi A1 on both Oreo and pie. So I decided to install a custom ROM but I can't boot my device to fastboot or recovery, it simply reboots . I tried the hard keys as well as through the PC using command prompt it just reboots normally. Any suggestions on what should I do Please?

Hi all.
I am going to flash LilneageOS 15.1 on my brand new A1.
We all know it DOESN'T contain any firmware blob (I mean, the stuff that usually drives the baseband modem, the wifi, the touch screen and so on) so I'd need to be sure I am on the latest one before flashing the ROM.
I've been unable to find here a "firmware only" release, also because in a few threads the word "firmware" is used as "ROM".
Is there anyone willing to point me to the proper post?
Please, be patient with me as I'm new to the Xiaomi world, but not new at all with Android and custom ROMs and recoveries.
Thanks in advance.
Hi, I recently flashed Lineage OS 15.1(Latest version) coming from Stock 8.1 August Update.
I suggest you follow the guide on the Mi A1 Lineage OS wiki which I followed and also use GApps(this survives OTA updates or something) provided by Lineage OS maintainer in his thread + 17.x magisk.
However ok Google does not work from Google App, assistant, maps, etc but the mic works fine.
I have seen people say flashing 8.1 May Beta modem(firmware available here) fixes the issue - see attached image - although I haven't tried it myself.
Hope you have no issues with Lineage OS, it's a bit complicated to flash on this device as it is A/B partition. Ok Google hotword is the only problem I have faced which is outweighed by the many essential features Lineage provides over stock.
If you need additional help please ask, because I myself found it tough to flash initially.
Edit: Having flashed stock GApps zip I also had the issue of camera FC, which was fixed by installing this camera through Magisk, which I will recommend anyway for better photo quality.
I have just started the process with TWRP recovery by following the LineageOS wiki up to step no.5.
The device is not booting to recovery but rather to system. So I am stuck here.

If you have already done the
Code:
fastboot oem unlock
then reboot to bootloader(Hold Volume Down + Power) and once again do fastboot boot "recovery.img". That will get you into recovery mode.

Yes, I did the unlock.
What you say deviates from the original wiki.
I am now updating the system so maybe I get the latest firmware.
I will try again soon after.

Nope. It doesn't reboot, even if the command line says it did.
I have found something about this problem, but am really puzzled as the official wiki isn't mentioning anything about A/B slots.
Hi - I am trying to reinstall TWRP on my OP6T after upgrading to OOS 10.3.0.
I am running Minimal ADB and Fastboot v1.4.3 on my Win10 PC. I have connected my phone to my PC, and entered Fastboot mode. The OP6T is detected when I do a fastboot devices command.
Next, I try doing a temporary Recovery Mode boot into TWRP with a fastboot boot twrp-3.3.1-1-fajita.img command. This is where I run into a problem ... While the Minimal ADB and Fastboot window says that the TWRP image was sent to the OP6T, I am still stuck on the Fastboot screen, and the phone is locked up and doesn't reboot the image.
What is going wrong?

Thanks, @jp0469! This helps a lot!
Just to be clear (and to get to a successful conclusion without a bricked phone), I won't be installing a TWRP installer ZIP file after booting into this TWRP image (The old style method), but instead installing the same TWRP IMG file as a "Recovery RAM Disk", correct?

Need a little more info before you proceed.
I know you said that you're currently on Android 10.3.0
Are you rooted with Magisk? If not, are you planning on rooting?

I was rooted with Magisk, but that got lost when I did the 10.3.0 update. Definitely planning on TWRPing and rooting again, as long as it's safe.

Once booted in twrp via fastboot flash the installer zip. It has always worked and will always. Always latest version. And flash Magisk after.

Put the latest Magisk zip and TWRP installer (zip file) on your phone's internal memory if you don't already have them there. Now you can fastboot boot the TWRP img file (Q version). Next flash the TWRP zip to permanently install TWRP into recovery. Reboot back to recovery to make sure it worked and then flash Magisk to re-gain root.
Reboot
Thanks, guys - The only reason I asked about the alternate "RAM Disk" method was because it was listed as the installation method by the developer on the link that @jp0469 provided earlier.
I'll try the old-fashioned method, since y'all say that it works OK.

I always install the latest directly from Google. There is a link on this page to the latest version of Windows ADB and Fastboot. Just unzip the file you download into a directory of your choice.
Everytime I try to boot twrp It says waiting on device. What's that mean

After doing the fastboot boot twrp-3.3.1-30-fajita-Q-mauronofrio.img in Fastboot Mode, I installed twrp-3.3.1-30-fajita-installer-mauronofrio.zip in the booted TWRP Recovery Mode, and everything is working fine again.

Hi all,
I have this X00TD model, and I recently updated firmware to WW-16.2017.2002.061. The phone has Android recovery, and I want to install Lineage OS. Whenever I try to install Lineage, I get the error 21 "signature verification failed". I read somewhere that I can disable the signature check in TWRP. But TWRP fails to install, whatever I try. I tried 3 different unofficial versions of TWRP (as my phone model has no official version of TWRP) and in fastboot, when I give the command "sudo fastboot flash recovery <filename>.img", nothing happens, and the process just freezes, and I need to kill the terminal to end the process. I have Ubuntu 18.04 installed. ADB and fastboot seem ok. When I type "sudo fastboot devices", my phone entry comes up. Any help would be welcome. I don't have windows os.
Thanks.

If you can't install TWRP on pie, try reverting to Oreo with AFT and then flash TWRP in fastboot. Also make sure you have unlocked the bootloader whether by the official tool or the unofficial method. THIS WILL DELETE ALL DATA SO BACK UP.
Thanks arko. Is there Asus Flash Tool available for Linux also? Will try and revert. Thanks :svetius
Tried reverting to Oreo with AFT, doesn't work. I installed windows 10, but fastboot doesn't work.
#fastboot devices gives me no output. I have the Oreo zip file, any alternate way I can install it? As you mentioned, there seems to be an issue with the pie ROM on my phone. Any way I can downgrade to Oreo using windows/Linux?

Windows 10 ? Its bcuz Driver Signature Enforcement
Disable it and reinstall adb and fastboot drivers, it will work for sure.
Windows driver security wouldn't accept drivers without proper Signatures,so like i said, just disable it and you are good to go.
:good:
Tried steps you mentioned, doesn't work. In fastboot mode, #fastboot devices gives me no output. Looks like my pie ROM is buggy. Basically, I need to install lineage on the phone.
Hi all,
Finally got everything done in about 5 mins I booted up Ubuntu Mate (32 bit) on my other laptop, and found I'd already installed adb and fastboot on it from the repositories (not from google). I booted my phone in fastboot mode, and tried the #fastboot devices command, and voila, my phone got detected! After that, it was a matter of a few minutes, following the installation instructions (of twrp and lineage) from the lineage website. Thanks for all your inputs and help
P.S: I realised (again), after more than 2 decades, that windoze mighty sucks lol.
Hi,
Today I wanted change my recovery. I had the Lineage OS recovery, but i was trying to install the twrp recovery.
So, the guide of twrp says that you should boot the twrp via fastboot boot twrp.img and install via the booted twrp. But I mistaken the command and I wrote fastboot flash boot twrp.img, I tried to reboot and the device booted himself in fastboot with the enter reason "error boot prepare" and I can't boot into the system or recovery.
I tried to flash the official image downloaded from the Google Developers website, but when i run ./flash-all.sh, console get stuck. I waited for about 15 minutes but nothing. I tried even the official Android Flash Tool but after 10 seconds it says "Your device stopped responding. You may have to select restart in the bootloader menu in order for it to be recognised again."
Does anyone know how to help me? Thanks in advance.

It depends if your pc were authorized, if it was, you can use fastboot to flash the stock version of Android 9, just running the flash-all(.bat) script.

I just had an encounter with this. I was rooting my device (Pixel 3A) and messed up my partitions through accidentally attempting a downgrade which broke all my ****. I was unable to easily reset this device to factory, so it took me several days to figure out and root. I'm getting better though as a hacker, because a year ago this would have taken me a month.
I was able to enter recovery mode (lying down Android, NO COMMAND). From this recovery mode, adb devices -l recognized my device, although I was unable to get a shell.
At first, ADB was telling me the device was authorized, but I messed with a bunch of other stuff (tried to flash a bunch of different partitions and monkey around in general trying to install Magisk) and then ADB started telling me it wasn't authorized when I used devices -l.
Once it said unauthorized, I was unable to issue the device any commands with ADB, so I just used hardware keys to get into recovery mode. From there, I selected OTA update, and it got into sideload mode. At that point, I used adb sideload with the OTA package that I downloaded here https://developers.google.com/android/ota
^^^ That operation did successfully restore my device to factory
This following guide here describes the details of how to use hard keys to enter recovery on this phone (don't download anything from there tho, and make sure your adblock is on)

I just wanted to say, I've been wrestling this hardbrick for a couple of days with my Pixel 3a.
I've finally overcome it by sideloading the most recent OTA update after using a hard key combo to get into recovery mode. The hard key combo is hold Power Button, tap Volume Up, then release both. Then, all you need is to use the command:
adb sideload <OTA.zip>
^^^OTA wasn't the actual filename though, you can download OTA packages for Pixel 3A here: https://developers.google.com/android/ota
the OTA binaries are NOT the same as the factory images, which is here

Sideloading the OTA package brought my phone back from only having fastboot and recovery mode, even when flash-all.sh from the official downloaded firmware failed. Now I know how to undo damage that I cause by rooting this thing. Since I sideloaded newest firmware, it was also like applying an update. I easily got root after that, and I've logged the process. I'll make it into a guide soon
I'll just note that if you accidentally flashed the TWRP boot image instead of simply booting into it, I believe all you have to do is flash the stock boot.img to fix the problem. Obviously you can sideload the entire rom image, but that shouldn't be necessary.
Using the Windows computer (or whatever computer you are sending ADB commands from), download the full stock image directly from Google. Unzip it and then upzip the folder inside. You should find the boot.img file inside that folder. Take that file and then flash it to the phone using the normal ADB command: fastboot flash boot boot.img
While I haven't tried this myself recently, it should work in theory. The command "fastboot flash boot twrp.img" flashes the boot partition with a non-working twrp image, so replacing the faulty image with the stock boot.img should fix the problem.
If I did the same I would first attempt to manually put device in bootloader/aka fastboot mode then fastboot flash the stock boot.img , sudo fastboot flash boot boot.img --slot all
I only read the op (first post here);but I betcha that would have worked. Then sudo ./flash-all.sh and let it do it's thing.
