Just do a backup and upload it. Thanks

No one here from Baltic States?

Hey, just show me how to do it, and I will give you.

hi, please use this guide: http://forum.xda-developers.com/showpost.php?p=8917870&postcount=12
or if you have Thunderg installed, then just do a backup and upload these files.
thanks

Hmm, could you be more specific? I just bought this Optimus One like two days ago, and I'm feeling very newb (it's my first Android).
What do I have to do, to give you that system.img and what is that system.img file?

Hi, the system.img a backup from Android /system partition is a main part of the android. But this guide we just dump that /system partition, it's the easiest way.
I'll try to help you do that:
1. Is your phone rooted?
If you haven't done that, then use Z4Root(super easy app ) and you can get it from here: http://www.upload.ee/files/997919/z4root.1.3.0.apk.html
Download that file and copy to sd card and install.
Open that installed app and root your phone
If you need help with that, then there is little how to here: http://www.worldofnubcraft.com/285/rooting-a-lg-optimus-one-android-phone
2. OK, rooting done, now we need terminal app: You'll find that from Market. Just search "Android Terminal Emulator" it's from Jack Palevich and install that.
3. Now open the Terminal Emulator and enter these commands without "" and hit enter after command, these 3 command should be it:
"su" it asks for a root privileges and you allow that
"cd /system"
"tar zcvf /sdcard/system-dump.tar.gz *" and wait when it finishes. it takes some time. It's done when you see #, it takes couple of minutes max.
4. That file is now on your phone SD card and upload that system-dump.tar.gz file to somewhere and let me know

Are you sure about that?
I'm sorry, but it's not working. It gives me an error "tar not found". Any ideas?

By the way, what you can do with that file? What it contains? I'm just a newb, and I want to know everything about Android.
EDIT:
Is it possible to do that dump with Thunderg?

Go to market and install app called "BusyBox" and download / install BusyBox with this tool. After that it will work.

yes, i forgot busybox install that and give a new try

Ok guys, I got it. Before putting it live, I would like to know one thing. Does it contains any personal data, if so, what exactly? Sorry, for being so paranoid.

hi, it won't contain any of your personal data. Personal data is stored mostly on /Data partition and we didn't dump that. Thanks

Ok, so here you have it.
Optimus_One_Baltic_ROM_dump.zip - 89.2 Mb
And it's only contains branded ROM with no changes? That's great. What program do I need to restore my ROM to the branded one, if I'm going later to change it?

i think you should look to Thunderg... it's best way to make a full backup and restore after

Problem with TAR

when i try to make WORKING ROM folder of SWKTM.tar.md5 after changing it to .TAR using dsixda
i get this error
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_toggle_sidebar": "Toggle sidebar"
}

that means that your tar file doens't have the kernel in it (boot.img) you have to put the boot.img file inside of working folder also

Don't try to use the .tar.md5 file directly. Do this:
- Extract the .tar.md5 file to a folder, lets say "/home/yourname/Stock". You'll get these files:
Code:
amss arm11boot boot.img mibib oemsbl qcsbl recovery.img system.rfs
We'll need to mount the "system.rfs" one. Now, do the following:
- Under your home folder (/home/yourname/) create an folder and name it "mntandroid". Create another folder named "system";
- Open a terminal window, navigate to the folder where you extracted the .tar.md5 file and get root user rights (sudo su/your pass);
- Type the following commands:
Code:
mount -o loop system.rfs /home/yourname/mntandroid
(remember to change "yourname" to your username);
- A new window shold open, it is the "system.rfs" contents. Select everything and copy to the "system" folder you've previously created;
- On the file manager, unmount the "mntandroid" drive;
- Compress the "system" folder - not its contents - to a zip file. The name don't matter;
- copy this .zip file to the "original_update" folder;
- try again now, it should work;
You can make it even better if you download any kernel (like Battery Extender) and place it in the .zip you've compressed before. This way, your zip should look something like this:
Yes, without any "META-INF" dir. Leave it like this.
Also, don't use the kitchen install script, I've read somewhere that it doesn't works. Use the Stocklite or some other stock-based ROM script.
Tell me if it worked for you. At least, this is what I did
Oh, by the way, this thread is where I got the mount rfs thing. I've just simplified it for you.

install recovery using adb

Windows users should already have :
<<adb drivers>>

so u did root. u unlocked bootloader. u flashed a recovery and u installed a new rom. one day u start "digging" things to see if u can delete all the unwanted files so u make the phone faster and accidentally u deleted an important file and now it cant boot and it cant go into recovery. you are wondering what you CAN do now ! The answer is : Everything !
You can either go back to stock rom or
you can re-flash the recovery and then reinstall the rom.
1. Download the platform tools for your machine ( windows , linux or mac-os ). Here i have the adb fastboot for you.
2. Copy the recovery image to a location on your computer thats easier for you. The recovery image should have .img extension. If it is in a zip file, extract the .img file from it before proceeding.
3. Connect the phone to the pc and open cmd inside the fastboot folder you downloaded ( windows ). The others not on windows must use cd [path to their desktop,inside the platform tools where they see the adb file].
** If you are on a boot loop but the pc gets to recognize the phone even for a second then
4. Type
i) adb reboot-bootloader
ii) fastboot flash recovery recovery.img ( the command is: fastboot flash recovery [recovery image path/filename] )
5. When its done , reboot. Hold Volume down and power button to see if u get in recovery mode. :highfive:
Install the rom now the way you already know. There are many guides for that so i won't make a new.
cheers :good:
**Windows users can use this fastboot to unlock bootloader too. Lite fastboot commands guide provided here
**Linux users don't even need to download it , they can just directly download it from their terminal
I hope this thread helps a little those that dont know what to do when they delete an important file. *Pictures coming soon*

To downgrade to KitKat, download the following file to your PC and extract with 7zip or WinRar: https://www.androidfilehost.com/?fid=23991606952608110
Boot your phone into download mode. This is done by powering the phone off, then holding down vol- and power at the same time. Connect the phone to PC with USB. You have to flash all four files with Odin as shown in the following image:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Please be aware that this process will erase any settings, data, and media saved to your phone's internal storage and restore it to its original factory condition, now on KitKat. This process also takes a long time (at least 5 or 10 minutes) and will cause your phone to reboot on its own, and to boot into stock recovery at least once. It is important you leave your phone alone while it is doing so, and definitely do not disconnect it until it boots into the KitKat setup wizard screen.
To apply the security patch, you will now have to flash two files in stock recovery (vol+ and power). First download and extract this file: https://www.androidfilehost.com/?fid=96042739161891196 it should be named 2400258.cfg. You need to rename it update.zip (yes, this involves changing the file type) and save update.zip to your external SD card (it will not work if it's on internal storage).
Finally, you need to download this file to your external storage and flash in stock recovery: https://www.androidfilehost.com/user/?w=settings-dev-files&flid=37222 Please note this file has already been renamed update.zip. They must both be named update.zip for them to work; since this can be potentially confusing I'd advise you to either save them to different folders, or delete the first one after you're done with it.
Follow these steps and you'll be back on KitKat, with that all important security patch. Good luck :good:

[ROOT][VS835] How to root LG Stylo 2 Verizon

Rooting the LG Stylo 2 (Verizon) VS835
credits to hovatek for mtksu, diplomatic for mtksu and suboot, & topjohnwu for Magisk
Needed...
1. Init.d Support Script apk
2. mtk-su_r23.zip
3. Magisk-v18.1.zip
4. MagiskManager-v7.1.1 apk
5. suboot.zip
6. magisk-update-block.txt
DISCLAIMER: I'm not at fault if you f&#$ your phone up.
I'm using a computer to do this procedure, if you want to rework this to be done without a PC be my guest. It is possible without a PC. I just seen people needed root for this device, I happen to own the device, and figured i'd be nice and give back to the same community that taught me android development for years...
STEP 1:
Connect to PC in file transfer (MTP) mode. and make a new folder on the device root directory called init.d
STEP 2:
Extract the suboot.zip file and locate suboot.sh you need to place this file inside init.d
Now you need to create another folder named bin (inside the first folder you made)
STEP 3:
Extract mtk-su_r23.zip and inside the arm folder is a file called mtk-su this file needs to go into the bin folder
Extract Magisk-v18.1.zip and inside the arm folder place ONLY magiskinit inside the same bin folder
if you did this correctly your files should look like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
*note* you DO NOT need to put the magisk-update-block.txt inside the init.d folder. That's just where i placed it. You only need the URL for the next step.
STEP 4:
Now from the phone install MagiskManager-v7.1.1.apk DO NOT LET IT UPDATE
Open MagiskManager and goto settings > update channel > custom
and paste this URL from the magisk-update-block.txt or from below
https://raw.githubusercontent.com/topjohnwu/magisk_files/841e978604f989d04549013cd4dcc7e34aea5288/stable.json
Click to expand...
Click to collapse
Now you'll see that Magisk Manager thinks it is already up to date.
STEP 5:
Install the init.d scripts support apk provided.
* tick/checkmark on "Run scripts at boot time"
* Set Execution Delay to "No Delay"
* For Selected Folder set it the init.d folder you made, and then click save at the top right.
It will say 2 script files in this folder if done correctly
** NOW scroll down and click "Run scripts now"
It's free version so watch an ad... after 2 ads it will grant you pro access for 24 hours.
** Again click "Run scripts now"
You'll see "Show last execution results" appear below the "Run scripts now".
Your results should look like this.
Use root checker to confirm...
Thats it. Enjoy.
