My phone is booting to Fastboot after update. Any ideas?
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Axendo:
31/7 build: power off alarm not working (on my device).
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Palo_:
Happened to me as well. Reboot to recovery and formatting cache fixed it.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] SkubiDoo:
Didn't help me.

EDIT:

I've tried to revert my backup that I have done just before installing new update.

TWRP says me: can not mount /system (structure needs cleaning)
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Condemned87:
With touching fingerprint reader (while unlocked) the screen wont goes back to homescreen. That's feels new since update 31.07. - possible?
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] SkubiDoo:
:) finally after few weeks of updating phone without issues my phone is broken.

Can not do anything:

can not mount /system (structure needs cleaning)
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Dobsgw:
Format /system and /vendor from wipe menu

Then flash los again

Personally I updated as normal and had no issues so this isn't a universal problem.

Doesn't sound good though

If all else fails

See if you can move anything from the phone to PC and as crap as it sounds use Flashtool to reset the phone.

Fastboot twrp and wipe everything and restore your backup
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] neXus PRIME:
That is sad dude. What happened?

You can try downloading MIUI Fastboot ROM and use MiFlash to return your phone to stock status (there is also option not to lock bootloader)

That way you can return to stock and then use fastboot to flash TWRP and try other custom roms again.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] SkubiDoo:
I have wiped /system and /vendor partition - installed previous build and I was able to turn on the LOS.

After that I was trying to restore my backup and again it failed after 100% with an error: can not mount /system (structure needs cleaning)

How to restore my backup now?

What should I restore to make it work back with my appz and settings?

Please keep in mind I had Magisk 16.7
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Dobsgw:
Personally I would use miflashtool to completely wipe the phone clean and it will fix any parituon issues like system.

Then start from scratch either clean installing LOS or you could try to restore the backup

Update error

My xiaomi mi 6 will not boot after upgrade lineage microG 15.1 from 17.7 to the 2 newest ver. When I reinstall ver. 17 July it works fine. What can be the problem?
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Dobsgw:
You need twrp with treble support

If you use magisk you need the latest beta 16.7

Search here for treble to get results
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] fex42:
On the latest 20180731 build, Bluetooth is not working correctly: it is connected but still plays from Smartphone speaker. Also everything seems a bit slow. After going back to 20180724, everything works.

Another problem I have is that OTA updates do not work anymore. TWRP is booting but neither asks for the PIN nor starts upgrade.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] alasulumurat:
Use Shev twrp
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] SkubiDoo:

[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Dobsgw:
Read the thread.

LOS is treble now.

So you need magisk beta 16.7
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Chandler Muriel Bing:
GOT IT! Thanks.

I just tested a bluetooth speaker and sound is fine. I don't know about the slowness, but I don't remember changing anything.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] fex42:
I already do. Now I upgraded from 3.2.2-0 to 3.2.2-2 and it is still the same: starting an OTA upgrade from Android reboots the phone to TWRP but neither asks for an encryption password nor starts the installer automatically (as it has done in older versions).

Btw, I've got a number password, not a pattern.

---------- Post added at 05:26 PM ---------- Previous post was at 05:24 PM ----------

After some reinstallations it works now and it also is fast. Don't know what was the reason.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] JeeHaa:
Same here, I reverted to TWRP 3.2.1.1 which works fine.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Thorst1:
Sorry for my slow reply and for the brevity. You're entirely correct of course.

I use my phone as a daily driver, so I stay with LOS and I meant that with all my LOS updates, I've never had to factory reset, or even wipe.

I thought bluedeathscreen meant that we need to factory reset after each LOS update, but I must've read it wrong ?
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] sami.khawaja:
I just noticed in the latest ROM that the deep sleep is not working.

Is it working for you guys?
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] khanjui:
It's working fine for me.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] alasulumurat:

[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] LemonChoms:
:)Hey, I can't enter the system after I falsh the stock version of opengapps, but the pico version is all right. Is the stock version unsupported?:o
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] alasulumurat:
I've been using stocks, I've never had a problem. Before I install pico and set up google camera and then go to stock gapps
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] LemonChoms:
I flash ROM and then flash STOCK. After reboot, I can't get into the system,it will come back to TWRP.

Everything is carried out in accordance with the steps,all was wipe and format data.If I flash rom and pico will be start the system normally

I have no idea for this:eek:
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] khanjui:
Same here. You can also use mini variant of GApps.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Shiw Liang:
No offense here, the ROM is quite stable but the graphic performance is just really bad...imo...any good kernel suggestion?
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] TheFatality:
Los and RR has the best graphic performance for custom roms

You can't find better graphic performance in other custom roms. I can recommend hasty kernel, I had used with pixel rom and it was good.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Henkl:
Uhm.. hasty kernel does not seem to work with treble
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] TheFatality:
Hmm, you may true.v I have no idea about some treble compatible kernel.

[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Thorst1:
I use up to date global Dev firmwares, never had an issue with fingerprints.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] khanjui:
Same. It seems like something is wrong with the stable ones.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] rtk217:
I want to switch from global beta miui 10 to this rom. My phone has FBE and I don't want to delete all the files (i don't mind deleting system/data/cache/etc).

I have installed already twrp 3.2.1-1 (with the encryption support). Can I install this rom without full wipe of the entire phone?

Also how is the camera compared to the stock miui camera?

and one last question. I use the phone as the authenticator for my 2-step authentication with google. can this be damaged in anyway because of the system and data deletion?
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] cangqilai:
Hey guys, I met a problem using a console app called Termux to adjust some system values on my Mi6.

When Termux was just installed, settings service worked well. After a day or so, it became like this, "Failure calling service settings: failed transaction".

I've updated my LOS version multiple times but the problem is still there. Anyone who knows what this description means, and how to make it work correctly?
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Thorst1:
<I added number to your questions>

I'm not sure what you mean with FBE (guessing file based encryption but not sure how this relates to the full device encryption by Android I'm using) and how that affects the move to LineageOS. Answers to the specific questions:

1. No. You'll need to format your data, losing all your files. This is a requirement with the move from stock MIUI to any custom ROM, for as far as I know.

2. I do not really like the LineageOS stock camera, but I'm using both a MIUI cam (for portrait and zoom) which has identical quality to the MIUI stock camera, and a Google cam port, which has superior quality.

3. Not sure I fully understand this question so I'll answer a bit expansively: changing to LineageOS will mean a complete device wipe. So you'll need to set up the authenticator again. But using LineageOS (especially with Magisk) I have had no issue whatsoever using authenticators (using a few for my work and for my private accounts) or even stuff like banking apps, even with my device rooted.

Hope these answers are useful!

[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Farkat:
No any reaction adb and fastboot. Only physical programmator helped. Now phone clear and miui. Trying to restore.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Henkl:
Which last fw?
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] SkubiDoo:
Can you confirm last update does not brick the phone? :)
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Dobsgw:
LineageOS updates are absolutely fine.

Been running it since the moment it released.

I think they meant firmware packages?

Idk I am 99% sure it was user error. It would be hard to brick a phone with firmware built for the device

That said I haven't updated my firmware since the OP one lol
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] neXus PRIME:
i always flash the latest firmware available on XenonHD and did not find any brick. And I don't think a simple user can REALLY brick a phone unless he REALLY tries to.

These phones have really smart protections and fastboot is able to fix usually 99% soft brick issues.

I remember the HTC desire days where we even used to change the bootloader and custom partition sizes which was really risky but we did it.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] SkubiDoo:
Yeah brick is not the right word in here - however "brick" that happened to me, that I had to reflash everything from the beginning last time ;) I don't want the same situation..

EDIT:

Downloaded last build - flash from TWRP and phone is ok! ;)
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Shiw Liang:
Firmware can get your phone bricked! Mine couldn't turn on after flashing one, I had to go to a mi store...
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] neXus PRIME:
agreed, I believe there are some scenarios however that's probably when using corrupt firmware or wrong files
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Ericwyn:
Hello ，I saw a new branch on github android-device-xiaomi-sagit called lineage-16.0

so this means that sagit can get official lineage16.0 support? ?
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] neXus PRIME:
why not? definitely
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Dobsgw:
Of course when official LoS becomes 16.0 then we will start receiving builds for 16.0

It seems to be how LOS works

However it may be a while before 16.0 is launched by the LOS team as they will have to adjust the ROM accordingly. 15.1 only just recently became feature rich
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Kamil Kupiec:
It is better than MiuiPro?
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] neXus PRIME:
MiuiPro is also essentially android.... give him an answer which helps him.

---------- Post added at 12:21 AM ---------- Previous post was at 12:18 AM ----------

it's a custom rom based on AOSP which is open source code.

It's framework and apps are different and there are no miui services like mi cloud. just Google related stuff.

It's light weight and could give a bit better performance and battery but that usually depends on your apps and types.

stability is a bit less but not that it will bother you.... miui also has stability issues so it's a draw.

Try it and you can judge yourself. take a TWRP backup so you can revert to MiuiPro if you don't like this one
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] TheFatality:
When will the Lineageos 16.0 release?
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] movsesyanpv:

When it's released, it will be ready I reckon. :good::cowboy:
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] neXus PRIME:

This branch is even with lineage-15.1.

The actual commits dont really show any thing new , but i think he is only coding offline now and has not pushed the latest changes to git.

There is a new TWRP by Shev (3.2.3-0) would this be ok to use now I guess?

Probably... I just updated to the last version of LineageOS, using Shev's 3.2.2.0 version. No issues yet.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] alasulumurat:

Just flashed 07/08 update and it installed Magisk 16.3 with it? I'm now stuck in a boot loop! If I update to 16.7 magisk will this solve the problem? Advice?

EDIT: So I reinstalled via the Offical TWRP, still installed 16.3 Magisk as an addon but that may have been because I was using that before? Tried to flash Magisk 16.7 but gave me the ERROR 1 code and didn't update, it's booting now so will see what happens.

EDIT 2: I cannot flash Magisk 16.7 now as I still get the Error 1 message any ideas?

Hi guys! Is there a Miui camera for treble that we can use with treblized lineage?

Thank you.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Dobsgw:
Check my android file host page. Under los extras I made one a while ago with blankaf it works fine

---------- Post added at 11:07 AM ---------- Previous post was at 11:05 AM ----------

The person saying the official TWRP works for LOS treble is entirely misinformed.

I tried it to be sure and while it detects /cust it doesn't seem to detect it as being vendor so it will be hit and miss what works.

Stick with the shev-t recoveries for now.

Its hard for the strix to coordinate an official treble version when most ROMs don't need it
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] mELIANTE:
Cheers!

On another note, my smart lock settings are blank after I updated to treble lineage. Can anybody check if theirs is the same please?

I just want to say thank you so much for this Rom, the last few updates have been rock solid for me and the most recent update with the latest dev fw seems to be even more slick than the last, and I've not had anything to complain about with regards to the speed and performance on the previous ones!

Great work!!! :)

[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] singularity0821:
Be sure to set the permissions.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Thorst1:
Same here. I already had the original Verevka cam installed, flashed the A2 cam, permissions were still set, only force closes. I deleted app data and cache, no dice. Reinstalled the original app from Verevka, gave permissions, and that at least works.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] singularity0821:
Which firmware are you using? I'm on the latest one.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] SgtWendigo:
Reboot may help, but you may have lost Face Unlock since Treble support. Other functionalities should still remain working.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Thorst1:
I just checked. The very latest one, 8.8.9 I believe, doesn't have a distinction between Chinese and global, so I didn't install that one. So I'm on 8.8.2. quickly reapplied that and tried the camera again, still not working. But that might be due to the fact I have the old Verevka cam installed, of course.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Dobsgw:
Reflash the latest LOS

Then install the new verevka cam

The old one isn't treble

New one is

They conflict :)
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Thorst1:
Right, I hate reflashing, lol, so I used Titanium Backup to uninstall the old MIUI camera app and installed the A2 version again. After giving permissions, it works!
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Dobsgw:
Reflashing isn't the best lol

Your method is equally good :)
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Palo_:
I don't know what I am doing wrong but always when I install miui camera, I see application name "60" instead of Camera and it FCs all the time. I tried everything including wipe of system and vendor and reinstalling LOS. Camera related magisk modules removed. Any advice what shall I do to make miui camera work. Btw, I am on FW from 8.9.
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Thorst1:
I had exactly this issue ("60" is very familiar), in my case it was caused by installing the wrong MIUI camera (the 'by Verevka' one, made for non-treble Oreo). For me, removing that app and flashing the A2 cam was the key to success. I sadly cannot think why you're not having luck even after wiping everything.

issue with /vendor partition during magisk installation

Hello, second time encountered problem with magisk installation:

I've installed latest update to my phone from system updater, no any exceptions, but then i checked magisk it was not installed, so i went to twrp, and tried to install it using install button. installation failed with error: cannot mount partition vendor

then i opened /etc/fstab file and added record for this partition, mounted from terminal it, and installation of magisk was ok, but system can not start, so i had to install back 11 june version - magisk installed automatically and everything seems ok. so i suspect here is a bug in latest version.

can try to reproduce this - could you provide action plan, which logs should i collect.

also this problem occurred on my friends phone. maybe if affects only on "beggar" version of mi6 - we both have 4/64 version
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Dobsgw:
Are you using the treble enabled shev-t version of TWRP?

If it can't mount vendor then your twrp isnt recognising /cust as vendor
[Xiaomi Mi 6 ROMs, Kernels, Recoveries, & Other Dev] Reylonds:

Because the ROM ist treble enabled now.

You need to install shev-t TWRP like mentioned above. Download link should be found in some earlier posts. And you have to install Magisk 16.7 to get it to work.

Search continues

I've been trying almost all ROMs for Mi6 and I'm still getting random radio drops when I'm using 5ghz Wifi. If I switch to 2.4ghz it doesn't happen too often, but it still does. I found that stock ROM was more stable but I was still getting random drops. Sometimes it's so bad that all radio signal stops working and I have to reboot the phone.

Has anyone experienced this and have found a good working ROM for it?

Thanks.
