WiFi password loss after each and every reboot on MEIZU Pro 5

AlainW94

@ubuntoutou If your phone works well under Android, it is not an issue with a broken EFS partition. Under Android if you get your WiFi, Bluetooth and IMEIs working well, then the problem can be more related to the firmware. This is only my thinking... Do you get access to the log files of previously connected Wifi router to your phone ? If yes, try to read the previous log to see if you can find your old wifi mac address in your dhcp offered lease history, then compare it with the one of your phone under Android, like that you will be able to see if Android is not able to read the EFS partition and take a default MAC. But again, if that was the case, you should see the error message in your logs. what kind of WiFi band is your actual phone compatible ?

ubuntoutou

@AlainW94 I haven't tried to re-install Android and I am a bit reluctant to do so unless I have some evidence that this is the way to solve the password issue. I haven't tried the WiFi on Android. I replaced the factory OS with UT as soon as I got the phone. I have no reason to think that there was any WiFi problem with the factory settings. I don't know what WiFi "log files" are nor where to find them. I also don't know what WiFi band my phone is using.

AlainW94

@ubuntoutou I understand that you won't came back to Android ... anyway if you did it it's really easy to do, simply boot on twrp, copy the update.zip on your internal storage then use the install button from twrp and select your zip. The phone will reboot on flymeos. to switch back to UT, flash the recovery of Ubuntu, do a normal boot, activate the dev and debug mode, run the ubports-installer ... you only need the correct flymeos version, the one that has the bootloader unlocked or unlockable. I didn't read all your posts from the begening, sorry, was your issue present since the begening ?or since an ota update?

ubuntoutou

@AlainW94 from the beginning.

@UniSuperBox said in WiFi password loss after each and every reboot on MEIZU Pro 5:

The EFS partition is custom to the phone. Since you have Wi-Fi working correctly when you have Android on the device, it is unlikely that the EFS is the problem. It's more likely that your unsupported device has some hardware difference from our supported devices.

any idea how to investigate/fix this?

I do see that I get different mac addresses after reboots

adb shell ip link show wlan0

00:11:22:35:52:e4
00:11:22:7f:bb:5c
00:11:22:a8:1f:39

Edit:
I see "my" mac here

Intf0MacAddress=001122A81F39

instead of, I guess this line:
https://github.com/ubports/android_device_asus_flo/blob/ubp-5.1/WCNSS_qcom_cfg.ini#L36

and that file has a change date of today

ls -l /android/data/misc/wifi/
total 48
drwxrwx--- 2   1010 1010  4096 Mar  3 22:07 sockets

drwxrwx--- 2   1010 1010  4096 Mar  3 22:07 wpa_supplicant

and I have a file

cat /android/system/etc/init.flo.wifi.sh 
#!/system/bin/sh

# Workaround for conn_init not copying the updated firmware
rm /data/misc/wifi/WCNSS_qcom_cfg.ini
rm /data/misc/wifi/WCNSS_qcom_wlan_nv.bin

logwrapper /system/bin/conn_init

echo 1 > /dev/wcnss_wlan

that rm's this file

AlainW94

@ubuntoutou can you try this :

cat /var/log/syslog |grep wl0

For me it give :

Mar 4 23:01:48 ubuntu-phablet kernel: [ 4877.390473] [4: NetworkManager: 3207] [c4] ** Firmware version = wl0: Nov 24 2015 11:23:00 version 7.45.71.r5 (r587357) FWID 01-ec3fd0c **

I might have a fix for my nexus 7. Not sure whether this applies to other devices. And I'm, not sure whether this is save in all cases to do. Proceed with caution

strace /system/bin/conn_init shows that it looks for this file open("/persist/wifi/.macaddr", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory), but indeed, I don't have this

root@ubuntu-phablet:~# find /persist/
/persist/
/persist/sensors
/persist/sensors/sns.reg
/persist/properties

After I created them,

mkdir /persist/wifi 
echo 001122deadbf > /persist/wifi/.macaddr

that mac address remains and wifi is reconnected ok after reboot.

AlainW94

For a Meizu Pro5 the WiFi MAC address should start by 68:3e:34, this is the vendor id of MEIZU Technology Co., Ltd. the 00:11:22 vendor id is from CIMSYS Inc.

doniks

@AlainW94 oh, right. You can of course use a different number! You probably should. I just made one up. The "fix" is just that it remains the same after reboot

Marathon2422

@matteo ok, thought it might help,as it is annoying reentering, as there is no option to reconnect.
all your "symptons", are the same as on my m10 fhd.
except the "nvram 0x10 error " .
did you try the "skyneel" fix tho.

ubuntoutou

@AlainW94 "cat /var/log/syslog | grep wl0" gives no output at all.

AlainW94

@ubuntoutou Strange I have two Pro5 and both have this entry, can you please post your syslog ? Is your Wifi activated ?

I'm glad to come in here now with my experience. Which is exactly the same as described by @ubuntoutou and @matteo ; and specifically I have a MEizu Pro 5 TD-LTE edition. Albeit, as it is my stable daily driver device, I do not choose to flash it to the devel channel and install Anbox in the hope of getting a fringe benefit that it might somehow fix this issue. I have raised this before on the Telegram supergroup, but unfortunately to little avail. I suggested that the donors could crowdfund the developers to obtain all Pro 5 variants, including the TD-LTE version which has perennial availability on eBay, to triage problems which are observed on device flashes apart from the vanilla 32GB bespoke 32GB version. @dobey said to me in response (partially with regard to hotspot problems on the device, but also to this issue): "and let's say some dev agreed to help with the purchase of said device. what happens if they can't reproduce the same issue?. Well, this concern seems nullified given the confirmations of the problem by other users in this topic and elsewhere. Now if he/the other developers want other users to back up the hotspot problems to further justify the purchase of this specific device, well I'm sure those hotspot problems have been cited by other users in this forum, on the supergroup and certainly on issue reporting pages e.g. Github. But I would be happy to help move that forward by summarising the history of those bugs and clarifying confusion/issue drift where ever possible. So most certainly it seems that the next step is to create a funding tier to permit the 64 GB variants of the hardware to be purchased by the devs, and so that they can then look into these problems and hopefully triage them.

@AlainW94 I tried again and I got the following output for syslog:

cat /var/log/syslog | grep wl0

AlainW94

@ubuntoutou ok, then it seem that we have the same firmware version on the two models, there is another issue. did you find a specific error related to the wifi in the syslog or in dmesg ?

ubuntoutou

@AlainW94 Here are some errors found in /var/log/syslog:

cat /var/log/syslog | grep -i error

@ubuntoutou said in WiFi password loss after each and every reboot on MEIZU Pro 5:

We have to investigate this line

AlainW94

@ubuntoutou do you have this file : /data/calibration/mac_addr ?

phablet@ubuntu-phablet:~$ sudo ls /data/calibration/
/data/calibration/mac_addr

On my phone this file contain the mac address of my WiFi adapter.

ls -l give :

-rw-r--r-- 1 root root 18 Feb 11 13:31 /data/calibration/mac_addr

Try also this to check if there is a mac address inside :

sudo cat /data/calibration/mac_addr

Can you also make a search for that "@@@@ MAC" in your syslog ? on my phone it return WiFi MAC

ubuntoutou

@AlainW94 Yes I do have a /data/calibration/mac_addr file. It contains the same MAC address as the one displayed on Settings -> About.

Regarding the syslog file, here is the output for a search of @@@@:

cat /var/log/syslog | grep @@@@

AlainW94

@ubuntoutou Ok, we progress... normaly SN should display the serial number of the phone (the one you get with adb devices. And the two line should display your WiFi mac addresses.

on my phone it give :

Mar  6 19:02:40 ubuntu-phablet kernel: [    1.246534]  [5:  kworker/u16:1:   59] [c5] @@@@ SN 860BCMSxxxxx

We have now to find what part of the kernel is giving thoses informations, if anybody had an idea ... you are welcome
