Quiero rotear mi dispositivo
[G4 General] අධිරාජ (Adhirāja):
Hi,

So I have the Canadian H812 model. Now the command for that is the following:

dd if=/data/media/0/rootedsystem.img bs=8192 seek=65536 count=548352 of=/dev/block/mmcblk0

The file was simply named 'rootedsystem.img'. My question is, do I have to rename it to include the model number of the phone?

Also what if I didn't copy the rootedsystem.img file into the /data/media/0/ folder, but a different folder? Will I have to change the command?

Thanks guys.
[G4 General] divineBliss:
Name does not matter and of course path in command must match actual location of img file in internal storage - otherwise how will the command access the file?
[G4 General] අධිරාජ (Adhirāja):
So you're telling me if the actual path is /x/y/z/systemimage_abcd.img, i'd be ok with putting /x/y/z/systemimage.img

?
[G4 General] divineBliss:
Nope, that will fail and why would you want to do some ridiculous like having the command filename/path not match the actual filename/path?

Just follow the instructions given.
[G4 General] අධිරාජ (Adhirāja):
So why it is not mentioned in the instructions that the path for the if parameter has to match the place you copied the image file to?

Does it assume you always copy it to /data/media/0/ folder? Because I just copied it to the root of internal storage.. /sdcard/

so for me (H812 user) the command will be

dd if=/sdcard/rootedsystem.img bs=8192 seek=65536 count=548352 of=/dev/block/mmcblk0

and does the of parameter change?
[G4 General] divineBliss:
Verify that /data/media/0/ is the same as /sdcard/ . "of" parameter should match the same "if" path you read the system image from before rooting it.
[G4 General] අධිරාජ (Adhirāja):
/data/media/0 is not same as /sdcard/

when i go to /data/ folder, i dont see any folders inside that folder.

also, are you saying 'of' and 'if' path should be same??
[G4 General] divineBliss:
You should look up the "dd" command syntax to understand "if" and "of" parameters. I don't have your phone model, so can't help you any further. Good luck.
[G4 General] අධිරාජ (Adhirāja):
Yes I looked it up. Says dd command is to copy files. So why not just copy them using a file explorer instead?

[G4 General] demoncamber:
I'm going crazy, because I cannot find the current root method for g4's on 6+

[G4 General] divineBliss:
There is no known root method for G4s with Marshmallow that I've ever seen. People downgrade to Lollipop to root G4s.
[G4 General] dvhrkn:
Where is H818n IMG ?
[G4 General] අධිරාජ (Adhirāja):
Ok so I put the phone in download mode and used the dd command, but I'm sure something's not right. First of all, a few minutes into it, I get the # prompt again in the cmd window while running Send_Command.exe, second of all, the Firmware Update screen on the phone still shows 'Do not unplug the USB connection until the process is complete', and the process is still at 0%..

Please help, shall I unplug the cable and reboot the phone manually Or does the phone reboot itself once it's complete?

Also sorry for double/triple posting, I am very nervous I don't want to brick :crying:
[G4 General] අධිරාජ (Adhirāja):
Your post is MISLEADING.

/data/media/0 DOES correspond to the Internal Storage (ie, when you plug the phone into PC using USB cable, the top-most folder hierarchically.

If you copy the rootedsystem.img file to the Internal Storage, and open /data/media/0 with a root enabled file explorer, you can see the rootedsystem.img file there....

You don't have to modify ANYTHING. Please change this post....

[G4 General] Spookymyo:
You can't root Android 6.x marshmallow.

Downgrade to 5 and you can.

See this thread: https://xdaforums.com/verizon-g4/general/downgrade-mm-to-ll-lgup-t3322616/page18

[G4 General] Knowbody42:
You can root 6.x if you have an unlocked bootloader.

You're right but I thought the guy was on Verizon which means locked bootloader.

[G4 General] r4veren:
Hello, developers and enthusiasts, I've spent a lot of time reading these forums, but just can't find the answer:

Is there any way to root the US991**a LG G4 model? The firmware version ending in 'a' denotes a carrier-unlocked model, not US Cellular. I currently have Marshmallow installed, if that complicates matters even more...

P.S. I've no idea why this phone is not more popular. It's a 150$ great camera, perfectly performant modern device.

Oops, sorry was half asleep when i asked this and didn't notice rest of thread.

Just pull back cover off and pull battery as it shouldn't be in the middle of actually flashing anything.

btw, same issue here. dd commands just coming up FAIL for my LB stock MM H812.
[G4 General] divineBliss:
Only Lollipop G4s can be root using this method - won't work for Marshmallow. Bootloader does not have to be unlocked for this method.

[G4 General] ChristosPas:
I know this is a pretty old post, but i still hope someone answers because i cant find anywhere else a proper guide to root the g4. First of all i m following every step as close as possible. But when i have to enter the specific command to run, as well as the ''id'' it just says fail no matter what. I hope someone can help
[G4 General] lt.anthonydelgado:
We need more insight, what variant do you have
[G4 General] ChristosPas:
its the international h815
[G4 General] lt.anthonydelgado:
Which international variant? The 10c is the one I see supported by this guide. I have the Verizon variant which takes a bit more playing around with.
[G4 General] ChristosPas:
i did some research and found out that i had to had twrp, i tried to install it and i m pretty sure its installed successfully but nothing changed. It was still failing. The only thing that i read but did not proceed on doing was downgrading from 6.0 to 5.0 (mainly cuz i just wiped the data by unlocking the bootloader and dont wont to set up the phone all over again. Also even if i downgraded i would still have to upgrade the phone after the root soo...) I really hope someone can help, its really frustrating
[G4 General] lt.anthonydelgado:
The truth is you will need to unlock your bootloader in order to put TWRP and so in short you will need to downgrade to 5.0. you don't necessarily have to upgrade back up to 6.x it's your choice. Since I'm on a locked bootloader on my Verizon variant I'm stuck on 5.0 but I'm rooted and have Xposed and viper working and honestly it's been great. Yes custom ROMs would be awesome but it is what it is. I suggest you bite the bullet, downgrade and unleash your phones potential. I would if I could and that's exactly why you have come here.
[G4 General] divineBliss:
Well, if you didn't downgrade to Lollipop, that's the problem. I don't believe anyone has ever been able to use these instructions to root Marshmallow.
[G4 General] lt.anthonydelgado:
Exactly
[G4 General] ChristosPas:
well my bootloader is already unlocked. Have you tried lgdeveloper, i think i saw an option for verizon phones but i m not sure

---------- Post added at 11:59 PM ---------- Previous post was at 11:59 PM ----------

Thats what i ll try to do then. Do you know of any guide here on xda or should i just search? (i was about to downgrade using lgup but the method seemed a bit too sketchy for me)
[G4 General] divineBliss:
I have used LGUP to downgrade my VS986 from M to L in the past. Just follow the instructions. You'll have to search for them on XDA. Check the G4 section.

I'm not familiar with your phone model. Have you searched for root methods for that model running Marshmallow ?

VS986 bootloader can't be unlocked, so we had to use the OP method for rooting.

Good luck :)
[G4 General] ChristosPas:
yeah i have searched and everything leads back to the OP so my only option left is to downgrade...i m already downloading the 5.0 file, i ll make sure to let you know how it goes, i just hope the phone doesn t get bricked or stuck in a loop or something
[G4 General] lt.anthonydelgado:
You should be fine, if you get stuck hop on here there's always someone around
[G4 General] ChristosPas:
finally i rooted the phone. all i need right now is to go back to 6.0 or to 7.0. The only problem is that i dont seem to be able to find any guides lol
[G4 General] lt.anthonydelgado:
Man you're lucky, wish I could move up too
[G4 General] ChristosPas:
well yeah i guess i am, i just hope i find a proper guide
[G4 General] divineBliss:
Most people have to follow the OP because there's no other option to root for their model and then have to stay on Lollipop to keep root.

Don't know if you have other options for your model that allow you to update past Lollipop. Let us know if you find something :) .
[G4 General] Jostian:

DD comands for LG G4 Stylus H635

Hi hi ! First of all, a lot thank you for the sharing and the good work

.

I have the following situtation with my device:

-LG G4 Stylus H635A, Android 5.0.2

-Bootloader locked

-OEM button not in developer options. I do not think is a case of Kg State or Knox, but something disabled by manufacturer.

-No fastboot mode (trying with ADB commands, just makes phone reboot)

.

After and extensive research, arrived to the conclusion is probably not good idea to use a Oneclick method.

.

So, will give a try to this method, modifying a bit the DD commands, so it fits with my former model:

>>dd if=/data/media/0/rooted.system.MYMODEL.img bs=8192 seek=?? count=?? of=/dev/block/mmcblk0

and doing a root inyection with this

https://xdaforums.com/g4/general/lg-g4-100-root-success-directives-root-t3180586/page90#post81227309

--->You think it may work? Which values would you recommend for <<seek>> and <<count>>?

Have one of these LG antiques and over the years (been discontinued and locked up by Verizon since 2015 ofc) the prospect of rooting a VZW G4 13B got dimmer and dimmer as it wasn't even popular to begin with. Came across the pre-rooted 13B (you know which) and this thread and got the nerve to give it a shot since the goddamn phone is nearly useless and dies in 4 minutes if you run modern apps of any kind on top of the forced bloatware horse**** from Verizon AND LG.

.... and it worked flawlessly here in 2022. Couldn't believe it at first, but it worked and never got a single error or weird crash or bull**** from the VZW LG afterlife trying to take me back to 2015. So, for all 12 of you who still have one of these and wanna get your hackerman on, this will work if you can read and understand the basics of what you are doing on a system level. It's not rocket science, but it is linux sorta.
