Here we are not going to make an android app but its just MODDING
Tools REQUIRED
-APKTOOL
-Notepad++
-An Apk to work
first just decompile a apk by Apktool.. Then
Find These files
-> res
->smali
->apktool.yml
->androidmanfiest.xml
Now open apktool.yml and search for these lines
Apk file name- Snigdho.apk
PackageInfo
Cur_package: com.bel.android.snigdho
Orig_Package: com.bel.android.snigdho
For Example change them to:-
Apk file name- mynew.apk
PackageInfo
Cur_package: com.mynew.app
Orig_Package: com.mynew.app
Now save it and open AndroidManfiest.xml
And search for these lines
package="com.bel.android.snigdho "
Change it to for Example
package="com.bel.android.mynew"
Now open smali>com>snigdho
And rename “snigdho” to “mynew
It will look like "com.mynew.app
And save
Your Package Name is Changed
Now to change app name open AndroidManfiest.xml and search for these lines –
<application android:label =”@string/appname” android:name= “.SnigdhoApplication”
Rename It to –
<application android:label=”mynew" android:name= “.SnigdhoApplication”
And save it now!!
Now open res>values>strings.xml
And Search for these lines –
string name="app_name">Snigdho</string>
Rename it to for example
- string name="app_name">mynew</string>
And save it!!
Now if you want to customize it open res>drawable nodpi and there you will see some pngs customize them according to your wish
Now recompile and Sign The apk!!!

Hi there. Old dilemma on how to expand the number of Android phones into a pre-made fonts (4-6-8 pieces which normally used to be) just a piece of your favorite font, or even at 20-40. There are several possibilities for this already; flash recovery from flash zip from the XDA,fonts changer applications in the Play Store, etc, etc. Our current solution for our good, that we can not install the fonts chosen by the type and number of pieces of others, but what we want, and as much as we want. Lollipop and KitKat operating system as well, so far I have tested LG phones. I did not feel harmful slowdowns or system errors after 30-40 font. Finding the appropriate fonts on the Internet will take much more time than the change itself. TTF fonts look for.
What it needs for this operation:
1: Root
2: Root file manager
3: Notepad ++
4: A new font or fonts lack, and a few minutes of your life
By default it looks something like the font selection menu, depending on your phone / rom 4-10 pieces chosen from the letter:
After the change is then this:
Take the letter or letters you want to use a file manager to copy the system / fonts folder, and then modify the permissions to this: rw- r-- r--. If you enter more letters copying, modification group should be done faster. Feel free to highlight all the letters as well. Do not just folders, folder if the fonts folder.
Now, you can edit the file fonts_lge.xml, which is located in the system / etc folder. Because even copying the letters in the fonts folder, depending on the system still will not see it, but after editing this file.
Notepad ++ looks like the original xml file's:
After the change this way:
As you can see, but that's all that we need so that we insert name of copied letters:
<family name="Arial">
<font weight="400" style="normal">arial.ttf</font>
<font weight="700" style="normal">arialbd.ttf</font>
<font weight="400" style="italic">arialbi.ttf</font>
<font weight="700" style="italic">ariali.ttf</font>
</family>
Since the type arial four species were also found, (normal, bold, italic, bold italic) should therefore enter and inserted into the original xml file. But where there are only two (normal, bold), there's this:
<family name="Tahoma">
<font weight="400" style="normal">tahoma.ttf</font>
<font weight="700" style="normal">tahomabd.ttf</font>
</family>
Which entries are nothing but a plain ttf, there is this:
<family name="Hwedding">
<font weight="400" style="normal">hwedding.ttf</font>
<font weight="700" style="normal">hwedding.ttf</font>
</family>
It may find that some letters than we can find only three kinds of (normal, bold, italic), the more so, enter:
<family name="Garamond">
<font weight="400" style="normal">GARA.ttf</font>
<font weight="700" style="normal">GARABD.ttf</font>
<font weight="400" style="italic">GARAIT.ttf</font>
</family>
The editing syntax pay attention to the layout, images and Notepad ++ help him. When you are done, you copy the modified xml file in the system / etc folder, but not before the original file, create a backup or just rename example fonts_lge.xm away. The new set fonts_lge.xml file permissions: rw-r--r--.
Here you only need to reboot the phone, and if everything went well, the letters appear. It is not hard on the whole, it can be done in a few minutes, and you can use any fonts out what we want .... enjoy ....
If you have root, you can use iFont from play store, it is much easier...

True .... easier ... faster ...
But.....the iFont may contain errors and bootloop. Have I ever experienced. And in this way no matter how many fonts can be done ..... just one, or 200. And you can choose how the font should not have to choose a predefined blind. You just have to search the web you like the true type font, thousands of them.
But thanks for the tips and useful comments.

Tried iFont on my H955 V15c , and no bootloop, everything work fine. iFont replace you default NewSmartGhotic font with one you chose. It is easy to restore to factory font because backup is created automaticaly. I have downloaded some TWRP flashable fonts zips from LG G3 forums, extracted and copied to internal storage, than from iFont you can select fonts from folder on phone storage. Before apply you can see a preview of your desired font. So far, helvetica light looks amazing

Thanks OP, your solution worked like a charm! iFont refused to do anything because it couldn't detect that I was rooted.
I used LG smartword to download and just apply the new fonts in Settings>displays>fonts
you may have noticed this post at the modding thread (and maybe the Q&A thread), the reason im double posting is so others could see this one visibly, while the other is just a substitute to get the 10 post requirement (sorry to add the unnecessary spam / post)
requirements:
Rooted phone
file manager
some patience
and a healthy working mind
and twrp (in case of bootloop)
now anything you do below here is considered "DIY" if your device gets f***ed dont blame me
1. open your file manager
go to : /system/etc/permissions
make 2 new files
android.hardware.vulkan.level.xml
android.hardware.vulkan.version.xml
2.
open android.hardware.vulkan.level.xml
add this :
<permissions>
<feature name="android.hardware.vulkan.level" version="0" />
</permissions>
save & close
open android.hardware.vulkan.version.xml
Add this:
<permissions>
<feature name="android.hardware.vulkan.version" version="4194307" />
</permissions>
save & exit
3. Now the fun bit
go to /system/vendor
open lib/egl
copy libGLES_mali.so & paste it to lib/hw
rename libGLES_mali.so at the lib/hw folder to vulkan.mt6757.so
next
open lib64/egl
copy libGLES_mali.so & paste it to lib64/hw
rename libGLES_mali.so at the lib/hw folder to vulkan.mt6757.so
4. reboot and hope it doesnt bootloop
tadah, you're ready to game hard! , open aida64 and the devices tab, you will see "Vulkan Device - Mali-T880"
if you think this helps, do press the thank button
Hi. How can I root this Phone?
Sir,thanks for his post is very interesting for me..I now working on some port Samsung that have many files Vulcan including the files that you takes.. thianproces is possible to do trough the super.. and change the file names 7870 for the names mentioned for you?!and do it manually? Thanks for is for his support..are the same file including on firmware Samsung doc 7870 y 7884b
May be will can working it? What do you think
Hello, recently I looked into LG backup and restore application using static analysis.
Note: this is based on version lg bnr 8.0.26 from 2020-02-13, tested with 7.0.20 from 2008-12-31
Here is the extract tool:
https://github.com/Mysak0CZ/LBFtool
And here is the technical part (you don't need to read this, if you just want to extract your data):
The file contains 2 headers (one of them is referred to as "new")
These are XML documents encrypted using AES/ECB/PKCS5Padding + SHA256 and null IV with static password
Code:
cd562f61-5399-3978-ac76-7c54b0508010
And they look like this:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<BackUp>
<Common>
<Name>LGBackup_200217_1</Name> <!-- Name of the backup file -->
<Id>Randomly generated UUID</Id> <!-- Id of the backup file -->
<IsNew>True</IsNew> <!-- IsNew is same in new and old header -->
<Version>1.00</Version>
<Attr Name="product_model">LM-X525</Attr>
<Attr Name="os_version">9</Attr>
<!-- And other attributes including google email -->
</Common>
<BackupItem Category="settings_DB" StartOffset="59392" DataSize="136626" />
<BackupItem Category="MEDIA_DB" StartOffset="901169" DataSize="78393344" FileName="external.db" />
<!-- Other backuped items -->
</BackUp>
The "new" header has more information than original header, but same structure.
The attribute "IsNew" signals the presence of the new header. (and is True in both files)
All numbers inside file are in Big-endian.
And this is the structure of the file (decimal position):
Code:
0: Unknown - 0x00 for me
1: Int32 - size of the new header
5: Int64 - offset to the new header (usually 13)
13 ... EOF-33: data
EOF-33: 20 bytes - SHA1 hash of the password (if present, otherwise still data)
EOF-13: Int64 - offset to the (old) header
EOF-5: Int32 - size of the (old) header
EOF-1: Bool - Lock byte - the file is (0x01) or isn't (0x00) protected by password
The password is only checked during import, not used to encrypt data (so to remove password, just set the last byte to 0)
Every "BackupItem" entry has a "Category".
Special case is Category="APPLICATION" with this structure:
Code:
<BackupItem Category="APPLICATION">
<APPLICATION Name="com.lge.ime" StartOffset="19221586" DataSize="2385983" Package="com.lge.ime">
<Attr Name="com.lge.ime">com.lge.ime</Attr>
</APPLICATION>
<APPLICATION Name="org.exmple.app" StartOffset="1429652009" DataSize="3420160" FileName="org.exmple.app.tar" Package="org.exmple.app">
<Attr Name="org.exmple.app">org.exmple.app</Attr>
</APPLICATION>
<!-- ... -->
</BackupItem>
All applications are tar files that contain 2 folders:
app - contains the apk file
data - application's internal data
All other items have:
StartOffset - Offset inside file
DataSize - Self explanatory
FileName - Not all have this, but most do; it is the original name of the backuped file.
The files are not compressed nor encrypted.
Footnote: This is my first post on XDA, so sorry for any mistakes I made (including my english) and feel free to correct me/give me advice.

Nice job dude! just a the quick recommendation: I would suggest that you put your code on gitlab or GitHub so it will become easier for others to contribute
Sent from my OnePlus 6T using XDA Labs
Hi. I'm trying to use this tool but I don't know how to use it. I followed the instructions and downloaded Python. but none of the other steps are working for me. I have my backup on my PC and am trying to extract my files into normal formats as I wish to move away from the LG platform. Thank you.
---------- Post added at 07:20 AM ---------- Previous post was at 06:57 AM ----------
Nevermind, I found a work around.
For anyone else in the future wondering: If you select backup with the app on the phone and backup to the internal memory, it will create .pdf files of all text/images in internal storage>>Quickmemo+. This doesn't help to retrieve the audio or video recordings, but at least that way you can retrieve your text files/images.
Tried script on old backup, failed with error.

Hi! Your backup seem to be at least partially corrupted. (The new header position seems to start at 7021235167904623918, however the file is only 597864605 bytes long). Fortunatly there are two headers in the backup and the old one seems to be ok (You got "[+] Header read OK" for the old header). So you can try ignoring the "new" header.
To ignore the faulty header just set the relevant "FORCE_*_HEADER" to True in the script header. In your case just set "FORCE_OLD_HEADER = True".
Also note, that extracting contacts in readable format is beyond this script's current scope. This can however be done manually. After you get your data successfully extracted, look for export/data/contacts_DB file. This is a TAR file in which you need to find file "data/data/user/0/com.android.providers.contacts/databases/contacts2.db". This is the contact database as your phone stores it. To actually extract the contacts, you will need to find a way to convert the database to some other format (I have't looked into how the contacts are stored, you will need to do your own googling)
Files extracted but...
hello guys,
I also managed to extract my files using the hack mentioned above (force old headers to TRUE) since by using the default script i was also getting a similar error as above.
However now all of my files (pictures in particular) are corrupted and i cannot seem to be able to open them using several editors.
Anyone else had the same issue?
Thanks in advance!

Yes I have exactly same issue as you have. All exported files cannot be read.
Hello @tking2000 and @serlal, this script was written based on versions that are available to me. There are two possibilities of what is happening:
1) The file was badly corruped, however the old header stayed itact. (This is the likely case, if you are trying this tool because your phone refused to restore the backup)
2) The file was made by version that does something differently and the script doesn't account for it.
In the first case there is nothing anyone can do (short of trying some corrupted file recovery software hoping the corruption is only minor)
In the second case, you can try sending me a PM with following information, so I can have a look and confirm whether this is truly the case (and improve the script)
1) The script's output
2a) The <Version> and <Attr Name="settingVersionName"> from the <Common> part of the header
2b) If you aren't concerned about privacy or it is just easier for you: just send the whole header file
3) The version of the com.lge.bnr app (LG Mobile Switch); this is not necessary, but may help me
Feel free to censor anything you are sending with [CENSORED] (like your email or filenames)
I have no experience with python, but I have one of these lbf files and I'm trying to figure out how to make it work and all I get is couldn't get library pycryptodome. How do I get Python 3.8.3 to get this library?

Hello everyone,
I just finished an update, that should enable the tool to extract backups that have multiple files.
If you received "Exception: Invalid header length." in the past and your backup has multiple files, try the script now; your backups are likely to extract correctly now.
This is the likely case for: @Ninja_Toad @serlal and @tking2000
This was made possible thanks to @cheesyzombie who sent me the data I asked for.
@kamikazkid, You don't need to know Python to use this tool, the easiest way is to enter the commands in quotes on the github page into the console (To open the console Shift+Right click in the folder with backups and choose "Open command window here").
Just:
Download the zip on the github page (Under "Code" button)
Make sure the extract.py and your backup are in the same folder
Follow the usage, skip the 4th step and replace xxxxxx to match your backup name.
I figured it out, it was something with windows 10 and the version of python installation I used. Microsoft garbaging things up as usual, thanks for the help though. Thanks, I recovered my files from my old phone successfully.
I have no experience withc++, but I have one of these lbf files and I'm trying to figure out how to make it work, it is a great this forum
Is there a way to import the _DB files (contacts, messages, call logs etc.) back to a phone?
I asked before:

Thank you so much for this! I was able to extract the Messaging data from an LG G8 ThinQ. Does anybody know the easiest way to view that data on my PC?
Hi, you can follow these steps to extract data fron _db files:
1) Send the _db files like contacts_db, messages_db to any android phone
2) Double tap on the file and open it using File Manager (which is by default on Mi phones)
3) The file will now open as a folder. Continue opening the folders until you reach to the last file.
4) The last file is the database file. It won't open directly. Select the file and extract the file.
5) Now transfer the file to computer and you can now view it using SQLite DB Browser if its a contacts file or you can use any VMG reader if its a messages file.
Hope this helps you.
Hi @Mysak0CZ, just follow your instructions on GitHub but when I run the command on Command Prompt, nothing happens. Just like this:
F:\>python -m pip install pycryptodome
F:\>python extract.py LGBackup-201031.lbf
When I enter nothing happened. Kindly help to advise for this.
Thank you

Hi! Your backup seem to be at least partially corrupted. (The new header position seems to start at 7021235167904623918, however the file is only 597864605 bytes long). Fortunatly there are two headers in the backup and the old one seems to be ok (You got "[+] Header read OK" for the old header). So you can try ignoring the "new" header.
To ignore the faulty header just set the relevant "FORCE_*_HEADER" to True in the script header. In your case just set "FORCE_OLD_HEADER = True".
Also note, that extracting contacts in readable format is beyond this script's current scope. This can however be done manually. After you get your data successfully extracted, look for export/data/contacts_DB file. This is a TAR file in which you need to find file "data/data/user/0/com.android.providers.contacts/databases/contacts2.db". This is the contact database as your phone stores it. To actually extract the contacts, you will need to find a way to convert the database to some other format (I have't looked into how the contacts are stored, you will need to do your own googling)

Hi, I am trying to extract via your method but in the power shell in sending the command "python extract.py LGBackup_1x0x07.lbf" it does not execute and brings me back the initial path line. Do you have solutions in this regard? Thanks in advance
Ps. I use Win10
Worked so well. I only needed to recover images and audio recordings after realizing that LG backup tool won't restore on other brand phones.
Thank you!!

Hello, recently I looked into LG backup and restore application using static analysis.
Note: this is based on version lg bnr 8.0.26 from 2020-02-13, tested with 7.0.20 from 2008-12-31
Here is the extract tool:
https://github.com/Mysak0CZ/LBFtool
And here is the technical part (you don't need to read this, if you just want to extract your data):
The file contains 2 headers (one of them is referred to as "new")
These are XML documents encrypted using AES/ECB/PKCS5Padding + SHA256 and null IV with static password
Code:
cd562f61-5399-3978-ac76-7c54b0508010
And they look like this:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<BackUp>
<Common>
<Name>LGBackup_200217_1</Name> <!-- Name of the backup file -->
<Id>Randomly generated UUID</Id> <!-- Id of the backup file -->
<IsNew>True</IsNew> <!-- IsNew is same in new and old header -->
<Version>1.00</Version>
<Attr Name="product_model">LM-X525</Attr>
<Attr Name="os_version">9</Attr>
<!-- And other attributes including google email -->
</Common>
<BackupItem Category="settings_DB" StartOffset="59392" DataSize="136626" />
<BackupItem Category="MEDIA_DB" StartOffset="901169" DataSize="78393344" FileName="external.db" />
<!-- Other backuped items -->
</BackUp>
The "new" header has more information than original header, but same structure.
The attribute "IsNew" signals the presence of the new header. (and is True in both files)
All numbers inside file are in Big-endian.
And this is the structure of the file (decimal position):
Code:
0: Unknown - 0x00 for me
1: Int32 - size of the new header
5: Int64 - offset to the new header (usually 13)
13 ... EOF-33: data
EOF-33: 20 bytes - SHA1 hash of the password (if present, otherwise still data)
EOF-13: Int64 - offset to the (old) header
EOF-5: Int32 - size of the (old) header
EOF-1: Bool - Lock byte - the file is (0x01) or isn't (0x00) protected by password
The password is only checked during import, not used to encrypt data (so to remove password, just set the last byte to 0)
Every "BackupItem" entry has a "Category".
Special case is Category="APPLICATION" with this structure:
Code:
<BackupItem Category="APPLICATION">
<APPLICATION Name="com.lge.ime" StartOffset="19221586" DataSize="2385983" Package="com.lge.ime">
<Attr Name="com.lge.ime">com.lge.ime</Attr>
</APPLICATION>
<APPLICATION Name="org.exmple.app" StartOffset="1429652009" DataSize="3420160" FileName="org.exmple.app.tar" Package="org.exmple.app">
<Attr Name="org.exmple.app">org.exmple.app</Attr>
</APPLICATION>
<!-- ... -->
</BackupItem>
All applications are tar files that contain 2 folders:
app - contains the apk file
data - application's internal data
All other items have:
StartOffset - Offset inside file
DataSize - Self explanatory
FileName - Not all have this, but most do; it is the original name of the backuped file.
The files are not compressed nor encrypted.
Footnote: This is my first post on XDA, so sorry for any mistakes I made (including my english) and feel free to correct me/give me advice.

ok I am so lost. And here is the technical part (you don't need to read this, if you just want to extract your data):
that statement would make it appear easy. well the link only takes you to the code, there is no tool and nothing with "new" as header. so ive tried deciphering what to do for hours now and i cant figure npthing out. rooted and flashed my lgv20 and did a backup with lg bridge beforehand. trying to restore and phone connects to computer fine but doesnt regster in lg bridge so that is why i need to extract .lbf file. can someone make this easier?
hello..it ended up successful.but there is no jpeg or mp4 file on DCIM folder..how can i restore them?should i do somthing with the script? i don't know pyton
