Hi ,

i just flashed the factory image for android 11 with full wipe ( was on last beta ).

My phone refuses to complete the face unlock configuration. Telling me that it can't add new face data and that i should remove one before retrying...

i'm rooted and i already tryed a magisk module supposed to fix face unlock but no luck

help please ? ^^

Did you find a solution?
[Google Pixel 4 XL Questions & Answers] baleskoil:
Nope
[Google Pixel 4 XL Questions & Answers] baleskoil:
I found someone with the same problem here :

https://support.google.com/pixelphone/thread/24855830?hl=en

Any Idea how i Can try to reproduce the same effect without having to lock/unlock my bootloader ?
[Google Pixel 4 XL Questions & Answers] fezzy102:
As of right now me and you are the only two that seem to have this issue.when I get home from work I'm going to go ahead and I'm actually going to relock my bootloader and and do everything and then I'm going to unlock it and see what happens.I can let you know in this thread if it works for me and that way you don't have to waste your time unlocking and relocking
[Google Pixel 4 XL Questions & Answers] baleskoil:
Yes please :)
[Google Pixel 4 XL Questions & Answers] Suavie103:
i would say lock and unlock again and just install everything again
[Google Pixel 4 XL Questions & Answers] fezzy102:
So i locked the bootloader ,then unlocked it and did a fresh install of 11 and i have face unlock back
[Google Pixel 4 XL Questions & Answers] baleskoil:
Good .

I need to reflash the Factory image before relocking right ?

To be safe
[Google Pixel 4 XL Questions & Answers] fezzy102:
I locked the bootloader then rebooted back into the boot loader and unlocked it and then flashed
[Google Pixel 4 XL Questions & Answers] baleskoil:
Works for me too.
[Google Pixel 4 XL Questions & Answers] neo_lithic3K:
In past issues with face unlock, the fix was to perform a factory reset (Settings - System - Reset options - Erase all data) before flashing a new rom. Supposedly the chip that face data is stored is not cleared until you do a factory reset. Unsure if a full wipe clears the chip. You can try this next time ... may be easier than doing a bootloader lock/unlock.
[Google Pixel 4 XL Questions & Answers] fezzy102:
I tried that and it's a no go. Looks like bootloader is the way for now.
[Google Pixel 4 XL Questions & Answers] seipersei:
Hi, My face unlock is also messed up after updating to Android 11 (it keeps saying “fit face into frame” without letting me register my ugly face...)

Did you encounter the problem after rooting? I’m trying to figure out how to solve this, as I had no success with factory reset or flashing OTAs and factory images :(
[Google Pixel 4 XL Questions & Answers] mcbooth:
I had the exact same problem as you. face unlock became unreliable after the Android 11 upgrade, so I deleted face data and tried to set up again. It keeps saying 'fit face into frame' no matter the angle or the lighting. Did a factory reset and no improvement. I have never rooted or unlocked the bootloader on this phone. I informed google support and they are sending me a replacement.
[Google Pixel 4 XL Questions & Answers] dwj:
Just to share an experience with the community: After android 11 update I was having glitches with face unlock. (Totally stock, no root & all latest ota) This got worse until it wouldn't work at all. Deleting face & starting over didn't work as it just refused to even acknowledge trying to register anything. Then the auto brightness starting flicking up and down and finally half the screen disappeared under green flickering. A factory hard reset made no difference. I even did it twice but the welcome screen on rebooting was still covered in green flickering. Searching for a new phone reluctantly. I picked up my pixel 4xl again to see if I could think of a way of selling it for any purpose & it was fine! Set up & reinstalled a backup & everything including face unlock works perfectly like new. What was all that about!?

Can you describe full algorithm for noob, please?
[Google Pixel 4 XL Questions & Answers] 10kopt:
Stiil don`t working

I've done relocking bootloader, but it didn`t help, face unlock still not working, OC is stock, latest.
[Google Pixel 4 XL Questions & Answers] kingkong0821:
I dunno what's the situation of you guys

But let me share my experience

I was having lock screen lags in Android 11

So I flashed the previous Android 10 image

It broke the face unlock and still broken even after flashing the full Android 11 image with wipe

What I did was flashing back to Android 10 again

Then update to Android 11 through OTA

This also was the method in r beta to fix face unlock issues
[Google Pixel 4 XL Questions & Answers] xRogerxC:
This is a known problem, and so far Google has not fixed it. Unsure if they ever will.
[MTCD Android Head Units General] Flole998:
Hi everyone,

I updated my PX5 unit to Android 10 and since then it's impossible to get it to connect to my WiFi. I used Wireshark to find out what's going on and noticed that the device tries to use Fast-Transitioning instead of 802.1x for the association attempt, which will obviously never work. How can I properly report that bug so that it can be adressed? I guess updating wpa_supplicant should be enough..... Or can I do that myself somehow?

Thanks for your help

[OnePlus 3 Questions & Answers] orlan7:
Please Help!!!! New to all of this.

Firstly my phone hung and wouldn't turn on. Finally later at night after non stop trying I realised it open in recovery and fastboot mode.

Recovery had the following options: (Didn't try fastboot)

- Install from internal storage

-Install from ADB

-Wipe data and cache

-Advanced

-Exit

Tried all options finally did a wipe cache and partition in data and cache

I wanted to save my data so didn't try adb

later the next day when i tried again it wouldn't turn on at all. Brick mode.

Checked online came across. https://xdaforums.com/oneplus-3/how-to/guide-mega-unbrick-guide-hard-bricked-t3405700

used the Method 2. Managed to get recovery installed the OS as mentioned with the thread. Nothing dif.

It wouldn't boot completly. It would go to "installing Android aps" and then reboot.

It wouldn't open in recovery as well, just fastboot. The next day even the OS stopped loading it would brick again and only load fastboot "Device State: Locked"

Tried the above method again. Used the MSM tool few times but still doesn't go past. Will only boot in fastboot mode.

Can't find any other option.

Anyway to proceed?
[OnePlus 3 Questions & Answers] TNSMANI:
Re-download everything and try again. If still not successful, try the later versions of the MSM Tool (search XDA for a thread containing all the versions) and with it the later versions of OOS.

If still not successful, it might be a hardware fault.
[OnePlus 3 Questions & Answers] orlan7:
Tried to find the later versions of MSM tool. The one i used was 3.0.

I managed to find the updated OS.

I found a link for MSM tool 3.0.6 but it has limited download size of 1gb before you sign up & the file size is 1.5 GB. Will continue looking for another link.Hopefully it works.
[OnePlus 3 Questions & Answers] TNSMANI:
Check THIS thread.
[OnePlus 3 Questions & Answers] orlan7:
I have. Even though it mentions MSM tool 3.0.6, on dowload it is 3.0.0. Even though still gave it a shot, but its the same output. Only fastboot with device locked.

I have searched through Xda as well as google for MSM tool higher than 3.0, been unlucky. Didn't come across any for OP3.
[OnePlus 3 Questions & Answers] TNSMANI:
I don't know which file you downloaded. The one downloaded by me last year and successfully used was Android 9 OOS 9.0.6. It contains version 4 of the Tool and OOS 9.0.6. Version 3 of the Tool will not work with OOS 9.0.6. The Tool is specific to the OOS version.

Prior to that I used version 3 of the Tool and OOS 3.1.2 from the Mega Unbrick thread you linked and that too was successful.

Be patient and try again. I have also noticed that sometimes for some people, a few repeated attempts are required before being successful.

Good Luck!
[OnePlus 3 Questions & Answers] orlan7:
My Bad. Was under the assumption OS n MSM tool were seprate. Got it. many thanks.

Had to use the MSM tool more than 10 times, finally the phone started.

Thanks alot buddy. Appreciate your help and patience.
[OnePlus 3 Questions & Answers] orlan7:
So it worked for a while. Was downloading all aps, restoring settings. Then switched off again. Turned on 3-4 times loaded and turned off again.

[Samsung Galaxy S8 Questions and Answers] sunilgeorge:
After the most recent update, the phone got stuck in a loop with a message ‘Your phone is encrypted, enter your PIN’. Entering your PIN showed the lock opening but it took you back to the same screen. I tried to boot it in safe mode and it was showing a message ‘Optimizing apps’ and then it went black and died. It won’t turn on in any way even in a recovery mode. Connecting to a PC shows the Qualcomm as a device but doesn’t recognize it as a phone.
[Magisk] Sui77:
So I updated to 11 on my Pixel2XL and installed TWRP, no problems so far.

After that, I installed Magisk and got stuck at the Bootloader.

I flashed the stock boot.img and just booted into TWRP (no install) and installed Magisk -> Success

However, I want to install TWRP (permanent) and Magisk , but right now I don't know what does the trick.

[Magisk] V0latyle:
The canary project has been shut down and the canary manager apk is no longer available.
[Magisk] Didgeridoohan:
Uhm... No it's not and the Canary Manager is available for download on John's GitHub.
[Magisk] V0latyle:
The Canary project has been closed - it says so in the thread title.

The Canary manager APK available is only the debug one.

I was able to successfully root my Pixel 2 running Android 11 using this; currently Magisk does not play nice with TWRP, so you can either have root or have TWRP, not both.
[Magisk] Didgeridoohan:
The XDA thread for the Canary releases was closed, yes. Because the thread was no longer serving any kind of purpose (it had simply become too cluttered with useless noise). And the only difference with the debug version of the Canary releases, compared with the "release" versions, was more logging in the debug release. John decided a while back to only provide the debug release since the purpose of the Canary releases is to test and provide information to the developer.

Yes, this is known and that will likely not change until TWRP has been updated for A11.
[Magisk] V0latyle:
Yes I see what you're saying, I got an update for the Canary manager this morning.

Is the recovery issue known to be isolated to TWRP? From what I understand, someone can have a custom recovery installed on A11, OR Magisk, but not both.
[Xiaomi Mi Note 10 Lite Questions & Answers] ykjae:
Hey all,

I've never had this problem before with any other device. When you download a app such as snapchat or cashapp.. Even Facebook messenger it comes pre-installed with the apps specific notification sounds.

My MI note 10 automatically set all notifications to either silent or the default notification sound.

I can go into every app settings and download the correct sound but that just seems like a very time consuming way of correcting the problem.

Any suggestions? Thank you.

I will mention I'm using the masik rom but I don't think that has nothing to do with it because I had this problem on my stock Rom as well.
[MTCD Android Head Units General] lundapag:
Hi,

I have a Seicane PX5 for 2009 Toyota Avensis. I have upgraded to Hal9k 4.10 and upgraded MCU to MTCE_MX2_V3.56. (it came with MTCE_MX2_V2.88).

Everything else works fine but the unit is supposed to switch and display rear camera when it detects that reverse is engaged. However nothing happens.

Camera is connected to "Camera in". Also it does not seem that either of the two wires with "Reverse" on give any voltage when reverse is engaged.

Camera works fine as I tested in aux-video in.

The system is also supposed to switch to "Camera in" when it detects videosignal on there (according to seicanes website).

Anyone have a similar problem or any tips? :)
[MTCD Android Head Units General] Bob_Sanders:
Try manually feeding +12v to the reverse trigger wire (orange wire on Dasaita.. not sure about siecane) on the head unit and see what happens.
[MTCD Android Head Units General] lundapag:
Thanks for a good idea!

There are two cables labeled "Reverse". One goes into the "AVIn/out" the other comes out of the "ISO-port".

When I trigger the one from AVI with 12v it switches to the camera input.

When I trigger the on on the ISO-port with 12V it also switches to camera input.

So that one must be two reverse-triggers? :confused:

The one from the ISO-port I assumed is supposed to go to +12V when reverse is enabled but it does nothing when reverse is enabled (measured with voltmeter).

I do not seem to be getting any voltage from "Cam power" either (which I assume is to go high when reverse is enabled).

I have set this up with the supplied wireless receiver and transmitter and according to the manual from Seicane it should automatically switch over when reverse is enabled or it detects something on the input.

When I run it from the 12 directly and trigger either of the "reverse"-cables it displays the rear image perfectly.

Problem is that I cannot trigger either of the "Reverse"-wires as it is now.

Is it a problem with the MCU-version? I guess I can connect an extra trigger via wire from the reversing lights. but it is extremely hard to get wires into rear hatch (stationwagon ).

Any other ideas?
[MTCD Android Head Units General] lundapag:
Solved it by routing +12v from reversing lights to the "reverse"-trigger wires.

[Fuhu Nabi 2] timtech:
Hello,

I have a Nabi2-NV7A-US on Android version 4.4.2.

Kernel version 3.1.10-g812486-dirty

According to product version tapped multiple times:

Version 3.0.13; Bootload Ver 5.3; Device mt799

Recently, without changing anything or using the device for over a year, the Wi-Fi stopped functioning. I would momentarily pick up a SSID now and then but could never connect to it. I believed it was a hardware issue with the wifi chip but, after reading throughout the forums, I think it might be related to the firmware.

I tried to install 3013stock.zip by unzipping the contents and using NabiLab “return to stock” method and installed the stock recovery but this did not fix the Wi-Fi. Maybe I didn’t do it right? Next, I successfully installed TWRP 2.8.7 and rooted the Nabi. After reading literally thousands of posts, I started trying to troubleshoot via ADB shell and the TWRP command prompt to fix the Wi-Fi. I’m not Linux fluent at all but I gave it a go by what I was reading online. IP LINK SHOW tells me wlan0 is in “...state dormant mode dormant...” and I can’t get it to change. iwconfig is not an available command but ifconfig is. I tried installing Reverse Tethering 3.19 so I could access the internet through USB but that required at least one connection to Wi-Fi after each boot which I can’t do. That application installation could have screwed up a few things as well.

The built-in Wi-Fi tests (tapping product version multiple times) failed with “Read config file error. /storage/sdcard1/test_config.txt: open failed : ENOENT (no such file or directory). I wondered why it is looking in sdcard1 so, for grins, I put a copy of wpa_supplicant.conf into the directory and renamed it test_config.txt. This resulted in “Read config file error ./nValue update_config of type java.lang.String cannot be converted to JSONObject. After all the fiddling around, the Wi-Fi no longer finds SSIDs at all and the Bluetooth doesn’t work.

After three 8 hour days of toying with this thing, I am at my wits end. I know this device isn’t supported anymore and isn’t worth much, but I can’t stand to be defeated. Can anyone steer me in the right direction? The most confusing things I have read have to do with the TWPR/recovery versions I have to use when reverting to previous ROMS (ICS, JB, KK). Also, I can’t find the original fuhu_nabi2_back_to_stock_from_scratch.zip stock version 1.9.12 or the fuhu_nabi2_wifi_fix.zip that people have been using to fix their Wi-Fi. I guess I need a step-by-step route to get my Wi-Fi working again either with NabiLab, TWRP, ADB shell, or all three.

Thanks in advance
[Fuhu Nabi 2] BlueMarble:
I guess it's probably best to do a factory reset. I recently had success in resetting mine using this method outlined here https://xdaforums.com/showpost.php?p=63060270&postcount=2 . TWRP was not able to run any of the ROMs I used and resorted to this method as a last resort. I also used 3013stock.zip as the restore file for TWRP. It was able to go through factory reset, and I also have Wi-Fi working. Before doing a restore, I pretty much tried to use all of TWRP's methods of wiping to get it as clean as possible.
[Fuhu Nabi 2] timtech:
I initially factory reset via NabiLab. I then restored via TWRP by using the unzipped 3013stock.zip files in my recovery folder. However, that didn't involve any "wiping". Maybe I'll try it again and use TWRP to wipe/factory reset.

Thanks for trying to help me out.

I wish there were some wpa_supplicant or other linux wifi commands I could use to reset the wifi back to factory. My wlan0 disappeared and a "dummy0" took its place. Although, dummy0 doesn't have the same MAC address I see in my system status reports for the wifi module. I've been trying to teach myself rudimentary linux troubleshooting but with the limited commands available in this Nabi and my limited knowledge of linux, I'm running out of steam.
[Fuhu Nabi 2] BlueMarble:
Yeah I don't think resetting WiFi is necessary. Maybe try to use the original ROM that came with the Nabi or another, but updated to the latest OTA (would have to find the file as the servers are down). I don't think you need to use NabiLab as it might be causing a problem. I would do TWRP -> Advanced Wipe -> Full Wipe. Then, restore with 3013 or maybe with the original ROM updated to the latest OTA. I would also suggest root and then debloat if possible to see if that helps. I chose to flash the .zip file found here https://supersuroot.org/download/ (v2.82), rather than using the root option usually found at the end of TWRP.
[Fuhu Nabi 2] BlueMarble:
Also, the guys here were able to get their WiFi working again by deleting wpa_supplicant.conf . (https://xdaforums.com/showthread.php?t=2202688)
[Fuhu Nabi 2] timtech:
wpa_supplicant deletion

I already tried deleting wpa_supplicant but the one I deleted was in /system/etc/wifi. I just deleted the one in /data/misc/wifi with no improvement. WiFi is on and it shows "Searching for Wi-Fi networks" but never finds any. No change. :(

The wpa_supplicant.conf file rebuilt itself but now has much less information. One change it made was from cntrl_interface=/data/misc/wifi/sockets (an empty folder) to cntrl_interface=wlan0 which is an interface that does not exist in my system. I have lo, dummy0, sit0, & ip5tn10 of which only dummy0 has a MAC address although it isn't the same as what is shown in the system status for my wifi card. ip5tn10 is a link/tunnel6 with a 16 digit MAC of all zeros.

It seems like I need to get wlan0 interface back with the MAC of the Marvel SD8787 card and get wpa_supplicant.conf configured to use that interface. Looks like the wipe path is next.
[Fuhu Nabi 2] timtech:
I just went into TWRP/wipe/advanced/wiped everything but SD card. Recover 3013 from SD card successful. Installed KK3013bootloader.zip. Rebooted system.

Still finds no wifi. Wi-Fi test (tapping product version multiple times) failed. However, I do have wlan0 now using "ip link show" and it has the proper wifi board MAC address but shows a

state

and

mode

of dormant. If I turn Off the wifi with the soft wifi switch, adb shell/"ip link show" shows wlan0 changing from Dormant & Dormant to Down & Default. Turning it back ON goes back to Dormant & Dormant. "netcfg" shows wlan0 as UP.

Question, why do I still have TWRP when I boot into recovery kernel? I thought wiping everything would put me back to the stock recovery. What does installing KK3013bootloader.zip do. I'm confused.

https://bbs.archlinux.org/viewtopic.php?id=117204 seams to address my wifi issue. However, the iwconfig command isn't available to me. "dhcpcd wlan0" gives me the same waiting for carrier and timed out as the poster in that thread[IMG="dchpcd result"]https://photos.app.goo.gl/ZFWTEobXh9wRurCr8[/IMG].

I still think there must be a magic linux bullet to reconfigure my WiFi. However, with the limited command set available on the Nabi and my limited linux knowledge, it is out of my reach. I wish some XDA gurus could chime in and show me the way.
[Fuhu Nabi 2] BlueMarble:
Oh I meant to say format data. What was the original version of your Nabi (Disney, nickelodeon, original?) , do a restore with that Rom. The partitions may be different for different versions. Do not use Nabi Lab to restore, use TWRP method I linked. If format data was used and the restore was flashed, then your recovery kernel will be different. Instead it will show the broken Android logo and allow you to factory reset. Factory reset. That should return wifi. No need to reinstall bootloader, that was used to unlock your bootloader.

Edit: also have you made any changes to your router during the one year?
