WiFi password loss after each and every reboot on MEIZU Pro 5
-
@ubuntoutou as @UniSuperBox mentioned, the EFS backup and restore could solve your issue with wifi. You would need to flash TWRP_3.0.2.img from here:http://xep.8800.org/pro5/nougat/ with fastboot, then make a full backup of your UT with TWRP, save it on PC, wipe the phone, install FLYME ( the version with unlocked bootloader), boot and set it up, reboot to fastboot, flash TWRP_3.0.2.img again, reboot to recovery, create backup of ONLY EFS partition, then make a backup of just that EFS partition, copy it to PC, wipe the phone again, reboot recovery, copy the backup of UT and EFS to phone, restore UT ( or you can flash it anew if you prefer), boot and set it up... Reboot to TWRP recovery, restore EFS backup, reboot to fastboot, flash UT recovery. Check it wifi password is remembered. (You might need to delete the wifi profile and create a new one, not sure about that, just try.)
Only this TWRP_3.0.2 has the option to backup EFS partition, not the other 3.0 version.

Thank you @Stefano. I suppose this implies that the Flyme OS image includes the EFS partition, doesn't it?
-
@ubuntoutou yes, it does. Also any ANDROID.
-
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.
-
@UniSuperBox Thank you. Actually, I don't know if the WiFi is working correctly with Android. I removed Android and installed Ubuntu Touch as soon as I got the device. I haven't tested the password issue with Android.
Do you mean the EFS partition is custom to the serial number of the phone or custom to the Pro 5 in general (identical to all Pro 5s)?
I could check what hardware I have in my Pro 5 if only I knew how to install lshw or hwinfo. I am a bit worried about installing anything with apt-get. I once installed a package with apt-get and the phone wouldn't boot afterwards. I had to reinstall the whole Ubuntu Touch OS. Should I use a Libertine container to install such a small package as lshw or hwinfo?

@ubuntoutou
I had this on my m10 fhd, i used the fix on xxx.skyneel.com,which is flashed with twrp, it will stay, thru ota updates ,but if you change rc,to stable etc, you need to reflash it.
I know how annoying it is reentering the passwords !
it says it is for mtk devices ,worked for me tho. -
@Stefano just now I realized I have the TD-LTE one...interesting...so, from what you said, this model is the only one with 4 GB?
-
@ubuntoutou it is possible. I just did it: I have both installed on my phone and they work great when launched with the terminal. I used a software called ATU to install the packages but basically it installs those by apt-get command. I also rebooted my phone after that without any issue. I don't see very useful data among the reported ones with both the commands by the way.
-
@matteo No, there is also LTE international 4GB Ram 64GB version as well.
-
Your WiFi worked with Android, but did you get a WiFi service called " nvram error 0x10".
If you did and you flash UT, it will not show this error, and you will need to re-enter the wifi ,every time you restart it
Put TWRP on your device, flash the nvram zip, from " xxx.skyneel.com" check it out ,reflashing stock recovery,as needed, ota updates fix usually stays, .See if it works for you , while you figure something else out
-
@Stefano yes I have two like this one with no wifi issue
-
@matteo what is this software called "ATU"? Where did you get it from?
-
@ubuntoutou I think he's talking about that @KrisJace's tool (https://sourceforge.net/projects/all-things-ubuntu-library/files/releases/)
-
fwiw, my nexus 7 also forgets the wifi passwords.
-
@Marathon2422 yes I already checked in Flyme several times and I didn't get such a NVRAM error. That's why I excluded this issue among the possibilities. Thank you for asking by the way.
-
@advocatux yes this is it. Thank you advocatux :). @ubuntoutou anyway if you wish to use it, consider this is not an official tool advised by UBports but you have to use it carefully, because apt-get command is not supported on UT OS.
-
@doniks Nexus 7 were built with more hardware revisions, so this is interesting information, seems it might be a hardware compability issue.I couldn't install UT on Nexus 7, untill it got fixed by OTA-7, so this might be simmilar issue for Pro 5 and some Nexus 5 users as well. It's baffling.
-
@Stefano I also have a Nexus 7 (2013) and I couldn't get UT to boot properly until I replaced the version of Android I had with an older version of Android. I have no issue with the WiFi password on this tablet. The nexus 7 works remarkably well with UT.
-
Yes @matteo I would prefer ATU to be on the Open Store. I haven't installed it. I would prefer to install lshw and hwinfo directly with apt-get install or dpkg -i. But there are some dependencies. I know we are not supposed to use these Ubuntu Desktop tools on Ubuntu Touch. However I have managed to install htop with apt-get without much trouble. There is now an app in the Open Store for htop but it may just install htop with one of these Ubuntu Desktop tools, I don't know.

@ubuntoutou Good point, you can maybe try to downgrade first your phone on a old flymeos version in order to get different firmware and then install again UT. if that works, try progressive upgrades of flymeos ...
