[G4 General] vsTerminus:
Well, as of this morning my G4 has a loose charge port.

It's still under warranty (I can un-root it without any trouble) so I can get it replaced, but I'm concerned about being able to get back onto one of the more recent LP updates without being forced onto MM (and losing root).

Is there a Rogers KDZ somewhere?

Can I manually flash v10h (or similar) somehow?

Sorry - I know someone's just gonna tell me to use the search, but I haven't had much like finding the answer to either so far.
[G4 General] milan187:
Is anyone using an unlocked G4 on Wind? I notice sometime data is not working. APN is good. It shows H+ but nothing is going through. Phone is originally from Bell. I have WCDMA only selected in Network.
[G4 General] kwarwick:
I think you'll find that's a problem with Wind rather than being related to the G4. Lots of folks complain about the same thing with Wind and the general consensus seems to be that they have issues with capacity on the data side.
[G4 General] milan187:
Thanks for the reply. That makes sense. I am new to Wind, hope they improve things.
[G4 General] kwarwick:
My Mom had pretty much the same problem with Wind using an iPhone. Some areas in Toronto would show full signal strength but data was slow or non-existent. She ended up switching to Koodo and the issue was completely resolved.
[G4 General] Gorship:
Is everyone really throwing out their G4 because MM isn't rooted yet? It hasn't been all that long since release. The phone is still great with lollipop.
[G4 General] :
Is far as mine goes, Mmm just loving it right now with MM!

Battery life just improved really nice! 36 hours, 4-5 SOT.
[G4 General] milan187:
Man how? I only just bought the device so never used it on L but the battery life is pretty bad on mine. Device is hot even of I use it to browse a little. I tired 3 factory resets already. Have nothing special installed. Even went back to stock launcher to see if it would improve things. My wifes s6 seems to last way longer. I am lucky to get 12 hours out of the device. Love the phone just want better battery life.
[G4 General] Miketyler:
I had the same problem just bought the phone as well and the battery life wasnt so good so I went on amazon and picked up the powerbear battery and the thing is a beast lasts for days, give it a try you wont regret it.
[G4 General] milan187:
I can't really get over what it does to the looks of the phone. I really like the way it looks with the leather back. I would consider that if I always on the go though.

What kind of scares me in keeping the G4 now is that LG will stop sending updates and since we have a locked bootloaded we will be stuck with the last version they release.

It's my first LG phone, how are they in providing updates? Are they still supporting G3?
[G4 General] buski:
I had the g2 ,g3 and g4 and usualy its one big update like kk to lp or lp to mm.My gf has g3 and she still on lp no updates available....i usually just sell the phone before it loses tooo much value and add a bit of money and get the newer one.
[G4 General] three-armsally:
So apparently i can't update to MM because im rooted. How do I get around that?
[G4 General] milan187:
I did see in g3 forums that M is avalible for it but I guess not the Canadian models?

This phone would be so awesome with an unlocked bootloader.
[G4 General] milan187:
Can I downgrade my Canadian H812 back to L (5.1.1)? Will I be able to root then?
[G4 General] Opacac:
Well I guess my time with the G4 is over. No root on MM means its over... Back to the 6p
[G4 General] jmcorlett:
Notifications not sounding

Ever since the MM update, I've noticed that after an hour or so of use, when I receive a text or hangouts message, there is no sound. It seems to fix itself with a reboot but the problem comes back again when the phone jumps to the second WIFI connection. I've tried calling LG and they say I need to reset the phone, which I've done twice. Apparently their fix is to go back to L. Is this a WIFI issue? Has anyone else dealt with something similar? Aside from this, and the obvious bootloader being locked I've been fine with the MM update.
[G4 General] milan187:
Well I am now happy with the G4.

Downgraded to 5.1.1 L, and then rooted.

Nothing new in M that I use, even disable the Now on Tap.

With root I can change the dpi, 560 seems to be the sweet spot for me.

No annoying Priority notification always present.

I have H81210n.

Just did all this and having root is awesome.

Anyway I will update in a few days how happy I am with L, since I never used it on G4.
[G4 General] greganka:
is there any special procedure how to downgrade? or do you just flash the lollipop KDZ back on the phone?
[G4 General] milan187:
Nothing special. Used LGUP and flashed H81210N (refurbish), then followed root procedure to update to rooted H81210N.
[G4 General] milan187:
XPOSED also work on rooted L, man I see no reason to go back M now unless root comes.
[G4 General] karendar:
Just got my phone back with a new board and camera... Back to Lollipop. Guess LG doesn't like Marshmallow!
[G4 General] milan187:
Board was probably loaded before M released. All boxed phones come with L too.

I was on M but sticking with L for now.
[G4 General] AmonX:
Does the 812 have an option for flashing firmware stored on the SD card in the service menu? If so has anyone tried that option? On my way home I remembered about service menus as that's how you could network unlock the Samsung galaxy S3 for free (provided you were on 4.1.2). A google search for the menu gave me the code 277634#*# I do not have a sd card in and cant find the option. Is there that option with MM? The page was written for the 815 so it may only be in that version.

Though I am sure someone else considered this first lol here is the article http://www.phonearena.com/news/How-to-access-the-hidden-service-menu-on-the-LG-G4_id71670
[G4 General] Spudnubs:
IT would probably be just as easy to flash the firmware using LGUP
[G4 General] salsadoom:
Anyone have a working download link for Bell stock H81210E_00.kdz? The links on devtester.ro seem to be bad, I've adjusted the download links as per the page's instructions but I get "Not found!".
[G4 General] tahiriqbal:
I have G4 H812 (Rogers) and upgraded to Marshmallow right away when I received the notification. Now I curse myself why I did that. Anyways, the MM software version is H81220E. What do i need to do to root? Downgrade? If so, which System image would I require to downgrade to root.

Thanks a billion and one in advance.
[G4 General] milan187:
I did the same with Bell variant.

Anyway instructions are the same, if you want root you will need to go back to L.

Look on the first post of this thread. What I did was used LGUP and loaded H81210N (link in first post) to go back to stock, also download the same version that is rooted.

Anyway here are quick instructions from me for Canadian variant for anyone that wants to do it:

First go back to stock:

You can also read this and follow my instructions below which are the same just condensed

http://xdaforums.com/g4/help/lgup-install-kdz-mm-lp-t3249803

Download LGUP and install both the DLL and LGUP

http://xdaforums.com/g4/help/lgup-install-kdz-mm-lp-t3249803

Download and install Windows Drivers:

https://www.androidfilehost.com/?fid=24052804347823763

Use LGUP to load stock firmware, to do this open LGUP select upgrade then find the stock KDZ file, then close LGUP and open it again. Now select refurbish, your KDZ file should still be selected, click START.

Once you are booted copy extracted rooted image to the phone main directory. Should be named something like rootedsystem.img and should be around 4GB

Once you have done that use the procedure here: http://xdaforums.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765

This is the command you will need for Canadian variant, found on the second post of the thread above

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

Any issues let me know.
[G4 General] AmonX:
It was just wishful thinking... but yeah phone will brick if you modify it from stock and flash it with MM with a locked bootloader...
[G4 General] Miketyler:
Im having some problems installing Xposed Framwork, I have installed flashfire and the up-to-date zip and different versions, placed it on internal and external storages and nothing seems to be taking have tried multiple times, the screen just goes black for 20 seconds and reboots itself. Could it be a problem with flashfire? is there any other program I could use?
[G4 General] milan187:
First time I did same thing happend because I was loading the wrong framework. You need to do SDK22 for arm64, I did version 80.

Before that I was doing SDK21 which is meant for Android 5.0, and SDK22 is for 5.1.1.

Also make sure you are using flash fire 0.24 version.

If you installed the wrong framework you may want to run the unistall first, not sure if you have to, I did. then installed SDK 22 for arm64.

When things went correctly I saw the optimizing apps screen on boot up.

---------- Post added at 03:34 PM ---------- Previous post was at 03:29 PM ----------

I did 10N on my Bell device, then loaded 10N rooted (should be the same version you have stock) and as I understand 10N in the latest for Lollipop.
[G4 General] Miketyler:
Thats the file I downloaded xposed-v80-sdk22-arm64.zip and still nothing even tried the version 79. any ideas how and what to try next?
[G4 General] milan187:
It looks like H81210O may actually be the newest, there is a rooted image on the first page but is there a stock image for H81210O?

---------- Post added at 04:01 PM ---------- Previous post was at 03:59 PM ----------

Which OS version are you running? It did say on the instructions that it would not work for some people and they had to try multiple times.
[G4 General] Miketyler:
Thanks milan,

Got it with the different version of flashfire 0.24 had the latest one installed, Cheers buddy
[G4 General] milan187:
No worries, others have mentioned that we must use 0.24 for G4, I tried 0.27 originally as well and the phone rebooted in 2 minutes and nothing happened.
[G4 General] milan187:
Can anyone confirm what is the latest stock version for the H812? is it H81210O? If so where can I find the stock version, the main page has rooted version of O.

I am very happy with L and want to stay on it just want the best version.

Been using it for about 3 days now, rooted + xposed and I love it.

I have H81210N so if there is something better I am willing to move to that too.

Thanks guys.
[G4 General] eeeaddict:
Is there any support for TWRP?
[G4 General] Spudnubs:
Our device is locked up like Guantanamo bay, son.
[G4 General] newonsh:
Purely curious question but why is no progress being made on unlocking the bootloader? I see no real benefit to rooting the h812 if I can't install custom recovery or other roms. With twrp you can achieve full backups, flash custom Roms, reflash stock, etc. This phone has been out for almost a year and the G5 is coming in a month and I can't even flash CM yet. I would've figured unlocking the bootloader would be priority #1 for developers. Although LG could make it a hell of a lot easier if they just allowed unlocked bootloaders on all variants.
[G4 General] milan187:
Maybe it's secure enough that there is no way for developers to do an unlock. Really wish I knew what the status is.
[G4 General] Spin01:
So... does anyone know how I can mod/unlock the B3 frequency on my LG G4 H812 so that I can access a particular LTE network while abroad (i.e., Belgium) ? Or point me in the right direction?

I recently picked this phone up on sale and really love it...but I also recently realized it won't access 4G networks in Belgium...and I'm headed there for a good chunk of the year...I feel stupid.
[G4 General] myth_237:
is this method without bootloader unlock?
[G4 General] milan187:
There is no way to unlock bootloader.

Here is my update after a few days back on L and rooted.

Just got 4.5+ hours of SOT with 45 min of clash of clans.

Running great with xposed too.

Will stay on L for sure.
[G4 General] tahiriqbal:
Thanks a lot for your reply, [MENTION=6598013]milan187[/MENTION]. I had bought the G3 and I was not able to use 4G services in Pakistan because the LTE/4G band used in Pakistan is different than Canada. That's why I thought I should root and try to override the bands to be able to use 4G services. But then I returned the set and bought G4 818p and now I can use 4G services.

Thanks again for your time.
[G4 General] milan187:
Glad to be of help.
[G4 General] SaHiLzZ:
Anyone has the firmware file for Marshmallow update for any of Rogers/Bell/Telus?

[G4 General] AmonX:
Too bad we cant modify MM add root to stock and trick the phone into thinking it is the official unmodified update
[G4 General] tk2porte:
Hello,

I currently have a rooted version of H81210g installed and am wanting to upgrade to the rooted version H81210o. I understand that I need to flash the stock H81210g before flashing the newer rooted version, however the DevTester firmware link for the stock H81210g is unresponsive. Can I download this elsewhere? Please advise...

Thank you.
[G4 General] pegcitygeek:
Which L firmware is the "best" version? The last one before M I assume? Gonna stick with L until root is available for M (hopefully). I have a Rogers variant.
[G4 General] velveteen71:
So....just to be clear: if I want to go back to LP from MM, I should -

Using LGUP, install the H81210H kdz, then, to go get root back, I should install the rooted H81210H.

CORRECT?
[G4 General] Buddyjohn:
yes

OK - thats not what I am looking for.

To repeat... does ANYONE has the MM KDZ for H812?
[G4 General] milan187:
Look at the link on first post of this thread.

Pretty sure there is some M downloads there.
[G4 General] Azure1203:
So anyways guys, I sold my G4, and switched to a M9.

Some people PMed me and asked me to come here and post my thoughts.

I think the M9 build quality is better. With a similar case to what I have on the G4, I just think its a much better looking phone. More comfortable to hold. Usage wise I think I get slightly less battery life, which is expected with the smaller battery, but its still over 4 hours SoT with decent usage. I have Wifi all day and almost always 5 bars service on 3G so don't expect same results where you are in different environment.

The phone is snappy on 6.0, and I have it rooted which is super simple with the official bootloader unlock from HTC. The biggest problem is getting a custom ROM on there, as HTC has firmware that you need to have matched to the firmware that the ROM developers use. So the Rogers 6.0 firmware is 3.38 and most of the ROMs use 3.35 firmware so it can cause a lot of issues. There are a few ROMs like CandySix and CM13 that don't depend on firmware but there are still in early beta stages on 6.0 so lots of bugs.

This is an easy fix if you want to spend $25 on the Sunshine app to set the security of your M9 off, and then you can roll back your firmware or upgrade it or even install the developer firmware from HTC which gives you option to do anything you want with your phone. See, even if you do unlock bootloader, HTC still has a security features that prohibits you from rolling back firmware or doing other stuff like custom kernels etc, etc. The developers of the Sunshine app figured out a way to hack that but they charge you $25 to do it. Well worth it going from most replies to how it works in HTC section.

The Snapdragon 810 is super snappy, the screen is super great, the speakers are super great. I just think its a great phone. Screen is slightly smaller so you have to get used to that, but I think its a better size. I get what people were talking about now when they mention the build quality of HTC phones. Much better than LG.

Give it a try!
[G4 General] Ramsey:
I had the M9 first, then G4, and now S6.

S6 is really the best one for me. I loved the G4 but it had some issues. The m9 was/is really good and Sense is superb, though TouchWiz has officially beaten them all for me (it looks and functions greatly). I had some issues with the m9, it would roam a lot, heat up so much it was uncomfortable to hold among other things but a solid phone.

I hate that firmware thing on HTC phones, it was annoying and almost made me brick the m9, and hate locked bootloader on LG phones. Samsung is the easiest to root and to restore. Actually the Oppo I once had was even easier, you could even update ota while rooted.

Nevertheless, I am eagerly waiting for the M10, to see how it is.
[G4 General] Azure1203:
Yeah the firmware deal on HTC phones is stupid. Not sure why it is needed outside of HTC just wanting more control over the phone. If you're going to unlock the bootloader for people anyways, why not make a phone where they can do whatever they want afterwards?
[G4 General] spartan268:
I remembered the firmware business on the M7. I was dead in the water for a month or two since I didn't want to risk doing any form of a firmware downgrade.

I actually wanted to get the M9 instead but the S810 basically shot it down before it even got the chance. Now that it's 'cleared' up, the M9 is already toast due to all the bad rep. Ironically the 6P is getting praised left and right.

That aside. How's the camera on the M9? I got the G4 cause the purple tint left a bad taste in my mouth so I wanted something that excels in that department. The M9 on paper seemed alright but I saw some video reviews of how the camera is still trash compared to something like the S6 or G4.
[G4 General] Azure1203:
I'm not actually a big camera guy, but I do know from experience that the G4 had a great camera. Don't think I can truthfully answer that question. Sorry.
[G4 General] geminihc:
sorry but i cant even past the first step of LG flash tool the KDZ , it's giving me the Connection to server failed message (in the back it does go up to 9% and stops), not matter how many times i "retry" ... i've done this before ont he same computer for g2 and g3 before, so it's weird. i un and ininstalled the LG drivers ON this thread.

any ideas..?

im on the wind lg g4 (currently H81220x (6.0)) and flashing H81210n_00_1204.kdz

what does happen if go from H81220x to the rooted system images which is H81210x ?

UPDATE: well, screw LG flash tool.. didnt work for me no matter what i did, LGUP worked perfectly.
[G4 General] geminihc:
quite sure the answer is no.. but can we use flashfire to flash a custom rom..?
[G4 General] spartan268:
As you predicted... The answer is no. Need a recovery for that which requires an unlocked bootloader and yadda yadda yadda
[G4 General] geminihc:
Question , if I have a WIND H812 LG G4 (locked to WIND), and I successfully flash a TELUS ROM (stock->rooted) in OP's post, will my phone still be NETWORK LOCKED to Wind or is it now LOCKED to TELUS?

Thanks!
[G4 General] mb_guy:
Still locked to Wind. Sim unlock still required, you may not be able to unlock after you flash Telus. This may not happen with LG but is an issue on HTC with non stock roms. I would use cellunlocker or similar and unlock first.
[G4 General] geminihc:
I do still get the dialog window to enter the unlock code when I insert a sim card, so hopefully it will work. The issue is that cellu locker or other places say my imei is not able to unlock... Weird...
[G4 General] koontzy65:
Way to gain root ???? :D:D:D

http://thehackernews.com/2016/03/android-root-hack.html
[G4 General] PsychoAssasin:
Try ebay? I always get my unlocks from there. It was like $5

Just make sure you find specifically LG G4 with Wind, as many only do certain carriers.
[G4 General] geminihc:
yes i tried 2 different ones on ebay.. same result. I think it may be because of this...:

Abit long story, but I bought this new from WIND a few months ago, but switched to another carrier (Mobilicity) recently and unlocked it fine. But soon, the G4 had issues so I received a warranty replacement with a different IMEI. During this warranty process, the service center asked who the original provider was, so I said "WIND". I assume that meant that the replacement was locked to WIND again.

OK, np I thought, I would just get the replacement and unlock it again. But for some reason no one is able to unlock it. Is it because this new phone has never been activated with any carrier..? How am i supposed to do it? I no longer have the WIND sim either.

Thanks,
[G4 General] milan187:
If they sent you a phone that was locked to Wind you would not be able to use it on Mobilicity...

What SIMs does the phone work with right now and have you tried any that it does not work with?

Is it possible your phone is locked with Mobilicty and you need to request an unlock for that?

It does not matter if the phone was ever activated or not.

There is also a small chance that some IMEIs are just not in the database for unlock codes. If that is the case you can probably unlock the phone by rooting it.

Answer the questions above if you can.
[G4 General] AmonX:
How?
[G4 General] milan187:
Did not try it, saw a few methods online for other G4 models. If the $5 method does not work I would try this if I had to get it unlocked.
[G4 General] geminihc:
it is locked to Wind, i can confirm that. I brought it to a Wind shop to put in a Wind SIM and it works. Any other SIMs, it would pop up the "unlock code" box.

can you elaborate on unlocking the phone by rooting it? I did root it via the method here (so thats why its on Rooted LP (telus, i dont think this really matters)). any links I can research? ... the $5 dollar ebay unlocks are not working... maybe my IMEI is too new and not in database?

I did do a search on the IMEI and it is clean , but it said that it was "produced" Feb 2016 (very new).
[G4 General] geminihc:
great news, i finally did get my g4 unlocked... no ebay sellers could unlock it, only cellunlocker was able to but it took one week long , requiring an alt database

anyone know how to disable that annoying update notification since we are on 10x?

thanks,
[G4 General] buski:
Root and freeze software update with titaniumback up
[G4 General] psor:
What do you mean ?
[G4 General] AmonX:
Root your phone and then use the app Titanium backup to freeze "software update". You need to buy the app to do that. A lot of reviews are negative for that app is it worth it?
[G4 General] TheSynysterLG:
Successfully downgraded and upgraded to root on H81220f Wind Variant, which was hella scary because there isnt anything about that model number anywhere online ?but to sum it up. Put all my stuff onto my sd card, powered off. Flashed the H81210n STOCK KDZ using LGUP. Followed the root steps on the main page of thread and did without a hitch. All in all took around 20 minutes total being very careful. I can write up a simplified guide to anyone in the same spot I was. Literally just rooted for 60fps glory, ??
[G4 General] fleagalbaum:
How do you get 60 fps. I thought we needed an unlocked bootloader for that
[G4 General] TheSynysterLG:
No you just need to manually install the zip using es file explorer as opposed to using twrp which isnt available yet for us. Root privileges are still required though. Follow his guide exactly. Download the highest bit rate version and the stock just to be safe if you ever want to return to it. https://youtu.be/dQQt9VnMV6M Takes less than 5 minutes just take your time and go step by step. Any questions or if you want a similar explained guide just ask!
[G4 General] fleagalbaum:
Thanks for the info.
[G4 General] milan187:
Are you saying you have root on 20f? I don't think it's possible.

Sent from my LG G4
[G4 General] TheSynysterLG:
Then Im the first one to do it? My phones model number before was H81220f, purchased from a wind store and use on the wind network. successfully reverted it to H81210N then to the rooted version.
