hi again, so i've updated my H815 with the new official KDZ (v20c or d), and rooted with the new system.img.

strange thing : the command "dd if=/data/media/0/system.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0"

just took 1 second, and the # appears...

root has worked but the first root 10 days ago (with v20b or c) took 2 or 3 minits.

do you have had the same experience?

my att g4 keeps on saying security error at boot up after I inputed that command. help
[G4 General] RoyHinkley:
So yesterday morning I did the same thing a previous poster did - I ran the command in step 10 before I realized I should have stopped and come back here. The difference is my phone is a VS986. I pulled the battery to reboot thinking the worst but everything is working fine and I have root. Battery life today has been fantastic. Should I be worried that I screwed up something that hasn't reared its ugly head yet or should I be fine? Just wondered if I need to take action now or just let it be. Like I said, so far everything is working fine - mobile data, sd card, wifi, etc.
[G4 General] neo_lithic3K:
Do you have an AT&T H810 10B version and did you flash the AT&T H810 10G image? I did that and got the security error.
[G4 General] Mirzatron:
i ended up fixing it by using kdz method and flashing the puerto rican rom
[G4 General] zaferaxu:
where can i find the new system image for H815TR?
[G4 General] androidbotz:

The root method will work but make sure you use the 10b SEA rooted image and not 10b EUR/Int'l or anything else otherwise, you will loose exFat for your external SD-Card.

For 10c, same set of principles apply as above. For your phone it has to be ''SEA'' if you want exFat intact
[G4 General] hikku13:
if LG is really pushing out OTA monthly based like Google and Samsung (due to security concern like stagefright, improvement, etc), then how the root method will keeping up with the update?

isn't it gonna be hard to keep maintaining pre-rooted images? or we're forced to stick with the old firmware.
[G4 General] AvivEliyahu:
I just got an update of v10f in my h815l (Israel).. Any idea how to root it? I have the kdz as well.
[G4 General] Medizinmann:
I would use the inject root script and the dd-line for H815 in the startpost - this should work.

[G4 General] AvivEliyahu:
The system image given in the op is for 10c,wont it cause issues?
[G4 General] Sean473:
There are too many bricks with this manual method. Seriously, devs need to get a move on and make a 1 click method to prevent all this crap from happening.. Too much element of human error in this method..
[G4 General] Medizinmann:
That's why I wrote use the inject root script (as found in Post #446 of the Dual Sim thread in General) and make your own System.img

Then flash use the the dd-line from startpost to flash your rootedsystem.img.

Greetings

Medzinmann

---------- Post added at 02:16 PM ---------- Previous post was at 02:07 PM ----------

I don't see so many bricks.

But one could say use this method only if you have a KDZ for your phone available.

I am pretty sure the devs would give us a 100% save one click root, if it would be possible right now. Till then we will have to stick with this method.

I am actually much more interested in a bootloader unlock right now.

[G4 General] mic141414:
Hello,

I received my G4 (h815) a few days ago and have been reading the thread to root it.

I have the SEA version. I was wondering if this root method apply to it. Seems so. Correct?

But you say to use the SEA rooted image. I only see system.rooted.H81510c-EU.img in the first post. So i guess i cannot use that to root my SEA version ?

Could you please clarify for me as i really don't want to mess up anything. Thank you.
[G4 General] Jammin72:
lol at the idea that the Devs *need* to do anything. They aren't beholden to any of us that can't figure this stuff out on our own.
[G4 General] Shadicbypass:
You need to read the 2nd post. Our version is in the second post by autoprime
[G4 General] mic141414:
Thank you for that. I wonder how i did not see that.

You have been able to root it with no problem your SEA version? no problem after (battery etc)?
[G4 General] Shadicbypass:
Yep no problem at all. Microsd works fine formatted as exfat and i have not had any problems with anything at all. I would advise like the op says to make sure you do everything correctly.
[G4 General] Lock-N-Load:
Come on man, no one is saying anyone "needs" to do anything per se, you understand the OP of the comment is just explaining - which I 100% agree with - that this is not in any way a "low effort" root and that in 171+ pages is somewhat telling and people are messing up and botching the numerous steps it actually takes to do this root method. You are just nit picking his comment due to 1 word. The OP of the comment is clearly just explaining a true 1 click method would be truly "low effort". it is a suggestion, not a requirement. I think, in this case, a well knowledgeable & experienced dev finds something like this pretty low effort, but the average guy out there.... not so much: proper downloads to find, cryptic commands to type, drivers and environments to setup, multiple pages to refer to, etc.

I have rooted many, many, many devices (phones and tablets) of mine and friends/family and I have been doing it since root started being done and was even more convoluted than this. I

love

root. But, I have actually not pulled the trigger yet on this root method - as much as I want root - as it honestly seems like a bit of a pain and having dealt with so many root issues & methods over the years, I am/was hoping for an even easier method given I have less time these days to jump through hoops and run issues down should they arise. So, for now, I am holding off. Does this mean the devs "should" and "need" to make a 1 click method? Nope. Would many more love it and dive in? Yep. I dig and appreciate that this method even exists. No doubt. Personally, I would pay/donate for a 1 click method.
[G4 General] Shadicbypass:
I dont know if thisis important but i was able to backup the laf partition to my sdcard using partitions backup and restore by wanam. I was wondering if the laf partition might be important to achieving a bootloader unlock. I have the sea version of thisphone

Just got my VERIZON version today. It says I am Software VS98610B , build LMY47D. It asked me to update to a new version. I am trying to root with the system image posted on page 94. Am I on the correct version, or should I update?
[G4 General] STIKID:
U can root using 10b. Theres a root img and aend command for it. But if u want to update there is also one for 11a which is the update. I personally kept 10b.

[G4 General] ssmaster:
I didn't realize the file in the OP was 11A. Thanks for the info.
[G4 General] 6bowmans:
​

No, Sean473 is acting like a whiny, demanding ass, "devs need to get a move on." As mentioned previously, the devs owe us nothing.

As far as "low effort root" this method was easier than rooting the Epic 4G, Photon 4G, Evo 3D, Evo, and S2. The S4 and Note 10.1 were easier. If a one-click method were easy, then I am sure some other website would have posted it. I mean the devs lay out the steps to root plainly as well as providing steps to inject root. If one-click root was that easy, then it would have been done already.

If you have any of the variants and firmware listed in posts 1 and 2 and follow the extremely simple steps, then root is easy. The bricks have come from those not following the steps correctly, using the incorrect images, messing with build.prop, or attempting to inject root themselves. The only edition/correction from the devs might be to warn Spint users that there is no tot file to go back to stock to fix a brick.

[G4 General] indianx:
my phone is stuck at the lg logo anyone can help? I get sometime in the download mode ports.bat tell com4 port but i cannot run any commands anymore.

anyway i can get back at stock rom ?

I cannot even get into the recovery. Any solution?
[G4 General] AvivEliyahu:
Get the battery out and out it back. Get into download mode and use LG flash tool (I think that the name) to flash kdz that fits your phone model.(kdz=stock rom)..

Choose the ces option when using the tool, it will work (takes around Five minutes) and will boot. Note - it deletes everything on the phone.
[G4 General] AvocadoBaby:
woohoo I did it. 815T Taiwan version. I used the Hongkong prerooted img in Autoprimes post.

Took me forever. First android and didn't realise that "internal sd card" means main memory not the sd card.....

I wasted alot of time formatting my card into exfat so I could fit the img on there.... d'oh

exfat still works btw as KoalamanX pointed out in the Q&A
[G4 General] the_scotsman:
Nope, they don't need to do anything. If someone isn't comfortable doing things manually, then they shouldn't even attempt this. XDA is about smartphone development, and learning. It's not about spoon feeding. If you take time and read things properly, you won't have an issue, and you will hopefully actually learn something in the process.

And there have been very few bricks (that cannot be recovered), so I don't see the issue.
[G4 General] iamtha1:
Any att users out there.... How did this root go for u?

Edit: nevermind rooted first try.... Easier than peeps may think.... Thanks devs
[G4 General] dilligaf56:
Perhaps slightly OT, excuse this, but a quick question. I have a VS986 on Verizon.

T-Mobile here has a good deal on now which would save me $100 a month on our 4-phone plan. I have an unlocked G4 so shouldn't have issues with going to a GSM SIM.

If I switch from Verizon, do I need to flash a T-Mobile-specific image or will certain functions (e.g. Hotspot, which I use frequently) still work with whatever network it's connected to?

I don't use any other Verizon-specific apps. I use Handcent for SMS and Google Voice for VM.

Kids are on iPhones (5 and 6)...I'm pretty sure that they will work on GSM networks also, or so I've been told.

Thanks, and pardon the diversion...

"International H815 10c Version (NOT H815T, H815TR, H815P, etc - you will lose internationalization and possibly features):"

Where is the link to this hong kong version? I have an Aussie H815T and some say the international link does work, but I am hesitant to use an image that specifically says "NOT H815T".

Is there a better link lost in this thread? If so, can we move it to the first post under H815T?
[G4 General] the_scotsman:
The International one works for your H815T just fine. Many people have done it.

But there is also a rooted system specific to yours. it's in the second post under pre-rooted system images, H815T 10B HKG:
[G4 General] AvocadoBaby:
I am in australia. I read some people who used international for h815t lose exFAT compatibility for their memory cards. Not a big deal I guess since I was using FAT32. but I used the prerooted image in the autoprime link which is post #2.

I downloaded H815T 10B HKG in the prerooted images section. I was stuck for a while because I didn't realise internal SD means main memory coz I'm not up with the lingo. Then you use the command in the same post (Command to Flash System.img (All Variants): for the H815T for step number 7 in the original post.
[G4 General] Medizinmann:
You should still be able to get into download mode and flash KDZ like described in the back to stock thread.

Try normal flash first and if it fails CSE flasch(you will loose Data)

About to go get a new phone. My G4 is always hot and has the finding location icon. I know that out of the box, it needs to to an update to 11A. Should I stay on 10B to root or proceed with updating it to 11A when I get it and then root?
[G4 General] thatkindaguy:
Come on guys - If you would follow the directions word from word, from the very beginning to the very end, you won't have an issue. Everything will go flawlessly.

does it matter whether i'm on v10a or v10b of H815 SEA?
[G4 General] sefirosu0522:
Ok maybe I'm confusing myself but I have a question. The first set of instructions say to use system.rooted.vs98610b (I have the Verizon G4). Why does the run command have

if I downloaded the system.rooted.vs98610b file? Currently, I'm downloading this:

.

Once that is extracted, should it replace system.rooted.vs98610b on the phone's internal storage?

Sorry I just want to make sure I have this right. I just picked up the phone and I am on 10B.
[G4 General] :
As long as your the rooted system image matches your current Version it's good.

Yes, if you flash a different version you will loose exfat support. I advise OTA to most recent version and/or use inject root script if you are unsure.

[G4 General] antus:
Thankyou Medzinmann for the most helpfull post ive seen on this issue. In my opinion rooting your own image as described in the link you provided is the correct and best way to do this.

Personally ive been using a fedora linux live dvd iso in vmware as im currently on holidays with just a win laptop. Any live linux cd/dvd image should work fine in vmware workstation/vmware player/virtualbox provided it supports usb2 or faster usb passthrough.

You recommend OTA to latest then root with these tools? This is good to hear as i feared updating past 10b or 10c looses the ability to read/write the system image. My phone however has an older baseband than is shown in the HK 10b image thread and it'd be nice to officially update to latest to make sure i have the best firmware for use with my carrier, and unlike some carriers images there isnt much bloat and the carrier usage wigets are nice (though ive allready ripped the apks for those).

Now will i be tempted to root on the plane on wait 'till im home hehe. Tools downloaded.
[G4 General] billybob275:
If you're phone is on version 10b then use the system img and that command for (system.rooted.vs98610b) on page 94.

If you're on 11a then you'll need to use the one on page 1 with the command for system.rooted.vs98611a
[G4 General] nash211:
Hi:

I followed the directions and when I select the dd script to run nothing happens, I selected the right port, shows up in my device manager but does not load the new image, what am I missing, watched both videos.
[G4 General] varaonaid:
Huge thanks to the devs and everyone who has helped make root possible. I'm really grateful for all of the time and effort everyone put in to give this to the G4 community.

Couple of quick questions I wanted to clarify before proceeding...am I correct that this essentially does not alter the LG ROM that each phone variant comes with other than giving the user root permissions? Meaning this isn't flashing a different system (such as stock vanilla Lollipop or a fully featured G4 ROM rather than the carrier crippled versions) and whatever version of the G4 one has on their phone to begin with is what they will have after this process only with root access, is that correct?

Secondly, I noticed that it was mentioned two or three times in the flashing instructions that the devs will still be seeking a different rooting method, even though it's been achieved through this process. It seemed as though this wasn't the way they would have preferred to attain root. Am I correct on this? Is there a reason to wait if it isn't critical to have root right now? I've rooted my phones before but don't fully understand all the reasons why one particular method is preferable and what each one offers in terms of pros and cons. Any insight to help understand this better would be awesome. If I've missed the info somewhere, please just point me to it.
[G4 General] android404:
I believe you're correct: if you do all of this right, you delete your system and flash the same type of system, prerooted by op. If you do it a bit wrong though, you end up in a situation that might be hard to recover from (reflash kdz with flashtool, no kdz for some versions of the phone yet), and if you do it completely wrong you destroy your phone. I guess that's why a one-click method would be preferred.
[G4 General] Medizinmann:
Well you have a # then punch in the dd command and after a few minutes you get a # again - that's it.

After reboot you should be asked to update SuperSu - do it reboot and you're done.

I think it won't hurt anything. You're just asking it to run a script, but you never put that script on it, so it will just not do anything.

If i accidentally forgot to go back and to step 10 on the other website link is that okay? Because i followed everything here and after typing Leave it reboots so i assumed i was done, but totally forgot about the previous website to run the root script. Do i need to do this and if so, just go back into download mode, paste the command and done?
[G4 General] tedescop:
Ha thanks I needed that laugh.

Sent from somewhere via Nexus 6
[G4 General] RenaKunisaki:
There's no root script to run on the G4. You just push the system.rooted.img file, reboot into download mode, run the dd command, and run LEAVE (in all caps) to reboot.

There is a script which will modify an existing system.img to give you root. That's useful if you don't want to download a pre-rooted image (since they're huge) or one isn't available for your phone. It needs to be run on a Linux PC though (or another, already-rooted phone). If you downloaded the rooted image, you don't need that script.
[G4 General] Mystikalrush:
Ahh okay, then im good then. Thanks for the help. Everything seems fine, ive already got my rooted apps installed and now freezing and backing up all my stuff. So happy to have root on my G4!

If you use one of the prerooted system.img from the startpost you don't need any script. The inject root script is only needed if want to create your own rootedsystem.img.
