Latest unofficial TWRP backups bootloader and firmware (if you select it)

Nevertheless I ALWAYS recommend to do a backup with SALT at least once as this backups really EVERYTHING ( full mode can even backup your full internal storage which can NOT be done with TWRP) . A SALT backup is just a double protection as a full TWRP backup is usually all you need.

Restore in TWRP your TWRP backup and for SALT backup files you would use TWRP plus the dd command in an adb shell if needed (e.g. dd if=/sdcard/cust.image of=/dev/block/bootdevice/by-name/cust).

But again: restoring SALT backup files is for the worst case only.. But for that case it's good to have them..
[G4 General] ThePiGuy:
Would you recommend latest Marshmallow or Nougat unofficial TWRP (I'm backing up Marshmallow but I would be restoring it from Nougat or Oreo)?
[G4 General] steadfasterX:
If you do not encrypt just choose latest N one. Regardless of which ROM you currently use or will use in the future.
[G4 General] ThePiGuy:
Ok thanks. I just booted into it and had a look at the backup - I can see bootloader, and I can also see Carrier. Is the Carrier option the modem that is referred to in the v29a update?
[G4 General] steadfasterX:
Nope. Firmware = Modem
[G4 General] ThePiGuy:
I have just tried to do a backup with SALT, and it was working really well and then it froze on the System backup. Looking in the log, it appears there has been a timeout error. Could this have been because my Ubuntu VM locked whilst the backup was happening?
[G4 General] steadfasterX:
Well there is one open issue in SALT atm: it does not warn you about too less disk space. The result is it freezes on backup if you have not 32 GB disk space available and choosen the full backup.

In VirtualBox you can setup shared folders which then can be auto mounted on FWUL (choose persistent folder and to auto mount in vbox settings)

Choose a folder with at least 32 GB free space and choose that one in SALT.
[G4 General] ThePiGuy:
My VM has 58GB free space at the moment. The python error in the log was a usb timeout error
[G4 General] steadfasterX:
What FWUL version? Persistent or forgetful? If forgetful the disk size is defined by the RAM. If persistent the max avail is 30 GB. So out of the box none of them can handle a full backup atm without modifications..

...or do you have mounted a 58 GB disk in vbox and store the backup there?

Some devices / firmwares got a timeout issue like you describe in big partitions. I adjusted the timeouts already and fixed it for the most ppl. If that happens go to advanced menu and grab the log. Use a pastebin service like hastebin or pastebin and share the link
[G4 General] ThePiGuy:
I wasn't running it in FWUL - I already had a Ubuntu 16.04.3 LTS VM set up so I was backing up in there, and the allocated disk space for the VM had 58GB free. It only had 4GB RAM allocated though, so maybe this caused an issue. I can try again on a true Ubuntu machine to see if the VM was the issue
[G4 General] steadfasterX:
Just use your Ubuntu one is fine!

The RAM is just interesting when we talk about FWUL forgetful.

So just do it again and when it happens again grab the log as mentioned above.
[G4 General] ThePiGuy:
I just ran it on a native Ubuntu machine and it worked perfectly - I think the USB timeout must have been my VM.

Just out of interest, looking at the files, I can see a modem file (and also modemst1 and modemst2 - If I use the modem backup, do I need to flash these as well?), but I can't see a bootloader file. Is it under a different name?

Finally, now that I have a backup, where would you recommend getting the v29a files and how would you recommend flashing them?

Thanks for all your help
[G4 General] ThePiGuy:
Having said that, I just got an md5 mismatch error on my userdata.bin. Is there any way to backup just that partition rather than the entire thing again?
[G4 General] steadfasterX:
Nope modemst1 and 2 are when you have issues with your imei. Nothing which you need to restore usually. Those are also get backuped by TWRP when you choose EFS.

Regarding the way to go to N? Well when you're unlocked and you have TWRP: flash the zip from [MENTION=5461026]kessaras[/MENTION] . If you flash the full ROM ensure that it does not contain the recovery image as it would overwrite TWRP. I would also remove the laf file from there to ensure SALT will continue to work (some ppl have issues on N laf).

Was it really a mismatch so ERROR or a warning?

Yes but not in the GUI (yet):

Open a terminal

sudo -s

cd /root/programs/lglafng

sudo python3 partitions.py --dump YOURBACKUPFOLDER/userdata.bin userdata
[G4 General] ThePiGuy:
Ok thanks - I'll get going :)

Unfortunately it was definitely an error. I reran the entire backup and I got the same error - "These files are corrupt (md5 mismatch): userdata.bin" under the errors tab after md5 verification
[G4 General] steadfasterX:
Share the log
[G4 General] ThePiGuy:
I would but I made the mistake of closing and reopening SALT and it all got deleted. Would you like me to run a third backup to get the log again?
[G4 General] steadfasterX:
If you don't mind.. Maybe it's an issue I can fix. Up to you. :)
[G4 General] ThePiGuy:
I'll get it going
[G4 General] ThePiGuy:
All done! :)

How would you recommend sharing the log (it's massive - 39mb and XDA won't accept a file that big as an attachment)
[G4 General] ThePiGuy:
Ignore my last post - I zipped it and now its fine
[G4 General] steadfasterX:
Ok great. The reason is clear now.

The command to generate the checksum on the device just takes too long to get a result and so you get a timeout. The backup was created successfully though.

I will implement a better solution for this but it is only an issue with the ultra big userdata partition..

For the moment I can not fix it but I can say your backup is still fine ;)
[G4 General] ThePiGuy:
Ok great - thanks for everything :)
[G4 General] ThePiGuy:
One more thing, if I download the zip from your mirror (a link is present in the thread by [MENTION=5461026]kessaras[/MENTION] - https://xdaforums.com/g4/development/h815-nougat-stock-t3659860), do I just flash the LG-H815_Official_v29A.zip as I would for a normal custom ROM?

And, should I need to downgrade again, my TWRP/SALT backup won't cause any downgrading issues (my anti-rollback appeared as 0 in SALT)?

Thanks again
[G4 General] steadfasterX:
Yes just flash it in TWRP as usual.

Before that open the zip and remove the recovery and laf files.

Restore in TWRP is fine to rollback. It's the safest method and is enough.
[G4 General] ThePiGuy:
Ok that's brilliant - Thanks :D
[G4 General] ThePiGuy:
It does give a zip signature verification failed warning. Is this because I removed two of the files from the zip?
[G4 General] ThePiGuy:
It gives a zip signature error. Is it still safe to flash (I'm aware that if the bootloader flash goes wrong, I effectively have bricked my phone)
[G4 General] steadfasterX:
pls keep in mind the following:

When you ask for help (here or elsewhere) the ppl NEED the logfiles always. Even if you think its not needed it is good practice to share them anyways.

The reason is simple. Besides the fact that misspelling of errors can happen logfiles contain important stuff which often is not shown to the user in a GUI.

A logfile is the first start point even when you think its totally clear what is happening.

Your current issue is a good example.

You get a "zip signature error" but I guess its not a signature error but a checksum one. If you had shared the log it would be more clear. Maybe the message you see there is not a signature error or maybe its just displaying wrong. If I would had the log i dont need to guess here again.

So logfiles can help to identify the problem and also it can help a developer to fix an issue which may occurred unexpectedly.

Thats why i say: no log no cookies.

It costs me much of my time without a logfile. I need to re-download the ZIP you are trying to install (as I dont have it on any PC or phone). I need to search and identify if thats really a signature error and then trying to guess what has happened to you. This all takes about 1 hour of my time. If I would had the log.. all that is done in 1....5 min instead.

This is a general thing and is refering to ROM issues, TWRP issues, flashing issues, SALT issues, whatever..

so back to your problem. no log no cookies. ;)

.
[G4 General] ThePiGuy:
Sorry. I didn't realise logs were so important. Where do I find the TWRP log?
[G4 General] steadfasterX:
thats why i explained it ;)

I have just found it. I'll post it later when I have access to my PC
[G4 General] ThePiGuy:
Sorry for the late reply. I have finally tried again and got a log (attached below). It appears to be a zip signature error. Is this simply because I modified the zip to remove recovery and laf?
[G4 General] ThePiGuy:
Never mind - I risked it and it worked fine (it must have been my tampering with the zip)

[Xiaomi Mi A1 Guides, News, & Discussion] ludlum123:
What is AptX?

Click here to find out

I noticed that the custom bluetooth codecs( like the aptX, aptX HD, LDAC, etc.) are not working even if we have devices that support it( like earphones, headphones, soundbars, etc.) For example, I own a Samsung Level U wireless headset, which is compatible of aptX codec, but whenever I connect it with my Mi A1, the codec in Developer options switches itself to SBC.

So, I found a workaround for it on OnePlus 3/3T Device Forum. [MENTION=3927764]theduke7[/MENTION] has created a Magisk module which enables aptX/ aptX HD on One Plus 3. I flashed that module, and Voila! The codecs started working on my phone.

How will this help you?

AptX increases the quality of audio transmitting over bluetooth considerably. So you will be able to hear nearly lossless, CD quality audio from your device.

Just flash the below given Magisk module in Magisk 14.0+ and reboot.

For those who can't find the option,

Go to Settings >> System >> Developer Options >> Bluetooth Audio Codec

Link to the thread

Just thank [MENTION=3927764]theduke7[/MENTION]

Before posting, please check whether your wireless bluetooth device supports any of the above mentioned codecs.

No matter wich codec I choose, always revert to SBC....
[Xiaomi Mi A1 Guides, News, & Discussion] ludlum123:
Your wireless earphones are not aptX/aptX HD compatible, mate. I googled them just now.

Also, the module is sometimes unstable. It reverts back to SBC even when we choose aptX or aptX HD. A simple reboot should solve that problem. After rebooting, before connecting the wireless, go to developer options and manually select the supported codec, and then connect.

I have a Chinese version huawei mate 9 which has this issue, but another 2 Chinese version huawei devices (kiwi and cherry, which are honor 5x and 4x) don't have such issue.

There is a file called services.cn.google.xml in /system/etc/permissions on Chinese version of devices with Play services built in. (at least on my friend's S7 edge, which has 404 error when using Play store).

On my Pixel and Nexus 9 I can't find this file (no problem when using Play store). So you may try deleting this file and reboot device to see if it makes a difference. (I don't know if this will work as my friend's phone is not rooted he can't delete the file. Always make a backup before modifying system files.)

UPDATE: Confirmed working. Just delete the file and reboot your device.

It can also be done by deleting the following line from the file (If this doesn't work for you, delete the file).
