Unlocking the device by paying $30 sevice charge

Wind mobile app has an option to unlock by putting IMEI code. I learned that $30 fee will be chraged. Does it work? Let say, I unlock the bootloader and downgrade to LP and root the device. Then can I flash CM13 (for h815)? I believe there is no h812 version of cm13.
[G4 General] koontzy65:
this will not unlock the bootloader, it will unlock the carrier you can use with your phone
[G4 General] salsadoom:
Hi guys,

I'm trying to downgrade my phone to root it. Hit a bump here google isn't helping with. I've got my firmware ready (Bell phone, using H81210n_00_1204.kdz). I'm following this guide. When I run the LG Flash Tool 2014 I get the error "Connection to server failed. Try again in a moment." Am I following outdated docs or something? Thanks!

EDIT: Whoops, I WAS using outdated docs. Used the LGUP method, worked fine.
[G4 General] Miketyler:
Hi xda,

Can I reset my phone and keep root? My phone doesn't seem to recognize my SD card for some reason just shut off in the middle of the night.
[G4 General] nahsha:
hi guys, I've rooted my lg g4 successfully using rogers H81210h,

since then I am getting a prompt to upgrade to H81210n I believe. will I loose root if I upgraded to that version (remaining on lollipop)? also I'm on fido and this rogers firmware has volte option...I can't seem to take advantage of volte. and fido and rogers are using the same network...any idea if it's just not enabled for fido customers?
[G4 General] kyleruggles:
Don't upgrade to Marshmallow or else you'll lose root. My G4 just died 3 days ago, Bootloop issue, and I just read about it earlier that day, you may have a ticking time bomb.. I'm also on Fido using a Rogers H812 model, but I can't tell you weather I was using voLTE or not heh. God speed man, hope that bomb doesn't go off for ya.
[G4 General] nahsha:
I meant to upgrade within lollipop, not to marshmallow, would I loose root? you upgraded and got the boot loop? I imagine it can't happen on its own.. did you fix it?
[G4 General] Michael_M160:
did any one else get the new 20V June security update , it just came today for Bell and maybe other carriers
[G4 General] Fr3lncr:
I just received it but I'm on Bell (Virgin) as well.
[G4 General] kwarwick:
I'm on Virgin also, but haven't received this latest update yet. I had to manually install the last one (H81220u) with LGUP, which makes me wonder why I don't get these updates automatically. Could it be because my phone was originally a Rogers phone?
[G4 General] bdasmith:
20v downloading now

Im on virgin and just recieved the update....will report back after it installs.
[G4 General] bdasmith:
Well....its still at android 6.0, not 6.0.1.

Its june 1 security level, and so far caused no issues at all.
[G4 General] kwarwick:
If anyone can provide a link to manually download the 20v update it would be greatly appreciated.
[G4 General] whips:
Just got it today (virgin)
[G4 General] DLM2583:
Hey guys I'm on bell I have the new 20v version how can I downgrade this to root the device only reason I want root is to fix my memory card not being able to write to it

Which kdz. Is lollipop for my phone ...
[G4 General] locutusx:
Nothing on Rogers :(
[G4 General] kwarwick:
Did Rogers even get 20u?
[G4 General] MrTyperoi:
I'm with Fido and still with H81220e !
[G4 General] doomanix:
Question, would downgrading my G4 to Lollipop trip any flash/root counter?
[G4 General] locutusx:
i am still on 20e.
[G4 General] xtremepsionic:
I'm confused, the top post of the thread says no root for marshmellow, then there's a bunch of links for how to root the 812 right below it. So is this doable or not? I just got a Telus 20U.

Thanks!

And if there's no root for marshmellow, is there a guide on how to downgrade my 20u to lollipop with root?
[G4 General] ZeroSkylineX:
What's the difference between H81220H and H81210N for Rogers? Also I'm currently running H81220E and wishing to downgrade, am I to download H81210E or H81210N?
[G4 General] alexvtr:
Roger's update is now available.

Version # is H81220x.

Apparently it's still 6.0 and not 6.0.1 but at least we now have wifi calling!
[G4 General] qu3becker:
Someone has the latest Telus KDZ? I got the May update but I can't find July's. My phone received Roger's because I bought it there but I'm now on Koodo's network and I feel like it'd be better using Telus' modem.
[G4 General] locutusx:
While it may not say 6.0.1, it definitely has some of the bugfixes in there:

- SOT on Rogers 20x is higher than Rogers 20e. By 30 min or more.

- Android OS memory usage is also about 150MB *less* on 20x than 20e. Confirmed by monitoring my phone for past 3 days
[G4 General] alexvtr:
FYI, Wifi calling works great with Rogers!

However, I have 3 LG G4s and none of them could properly activate the function after the update (the option was there but the signup process could not be completed - said that a call to technical support was needed).

Rogers had to change some settings on their end to make it work.

Rather painless but annoying nonetheless.
[G4 General] Shadowdroid78:
Has anyone received or know when we should receive the update from Videotron?
[G4 General] qu3becker:
I don't think videotron released the update yet. I don't know for sure but have you tried LG Bridge on PC? If that doesn't work, you can call Vidéotron's technical support. I used to work for tech support and we received news for the updates every now and then.

hello, i need help i have installed H81210n rooted, and try install xpose with flashfire but no install, say system could no be mounted, any idea?
[G4 General] psor:
I can say that I have a better battery life with H81220x than with the previous version !

Very noticeable !

But, why not 6.0.1 though ??

[G4 General] Gorship7:
I updated my phone to MM and now I don't get service as well in some areas and my battery is awful. Tried a couple factory resets with same results. I'm on h81220u telus. Any ideas?
[G4 General] kwarwick:
Too bad that site requires you to use their downloader... great way to get your machine taken over with malware. Thanks, but no thanks!
[G4 General] phatryde:
I got a question to ask you man before I start my root and install xposed framework.

I used the LGUP to downgrade to H81210F also however I have no clue what I should do with the rooted h81210f image that karendar provided. Should I flashfire that or LGUP it? I'm so confused. Can someone please give me some noob steps.

My phone is LG H81210F on 5.1. I want to ROOT and install framework. I'm reading but just asking these questions to make sure I don't mess up.
[G4 General] gduong128:
Used the following settings in FlashFire:

- uncheck automount

- uncheck mount system read/write

I did it and got xposed working on my H812
[G4 General] Florad77:
Ok so I want to downgrade and root my rogers h812 and I've done some reading but just wanted to double check that I've understood everything correctly. Can some one please confirm if my steps will be correct?

To downgrade my Rogers h812 from marshmallow to lollipop and then root I need to;

1. Download stock H81210n kdz from here http://xdaforums.com/g4/g...lg-g4-t3212449

2. Follow method below to flash kdz

http://xdaforums.com/g4/h...mm-lp-t3249803

3. Download rooted rogers h81210n image from thread in step 1

4. Skip to step 3 of this thread

http://xdaforums.com/g4/g...-root-t3180586

5. Get xposed using this method

http://xdaforums.com/g4/t...ocked-t3181593

6. Profit?

I would really appreciate it if someone could let me know if all these steps are correct and if I need to do anything special or different for my specific model in any of these steps.

Thanks
[G4 General] Unoder:
Anyone? I have the exact same phone & I'm looking to do the exact same thing.
[G4 General] Florad77:
Ok I went through with it and can confirm everything works perfectly. Just follow all the steps in the threads carefully, it'll tell you when you need to do anything device specific.

And for xposed, when flashing the zip through flashfire uncheck mount system read\write. Wasn't mentioned in the thread but i needed to do that to get it to work.
[G4 General] ILIVE4HEAD:
so I have software version h81220u and I want to downgrade back to lollipop so this means that the lollipop version i would need would be the h81210u? I couldn't use any other stock h81210x kdz?
[G4 General] NickSVT-40:
how to install the true 6.0.1 update into H812?

Hi. i'm new to this, i mean really new lol.. i made the switch from iPhone about 1 month ago and bought my LGg4 H812 used. it was blocked to Bell so i had it unlocked to use on Rogers. using treads here on xda i managed to flash H81220x using the LGUP tool. i was so hopping to get those new Emoji's but turns out it's yet another disappointment.

Is there actually a way to install the real 6.0.1 into my phone?

or at least getting the new Emoji's into this H812 model?

Thanks

H81210G Telus

Trying to get the kdz for the H81210G of Telus from devtester.ro...

Doesn't seem to work, tells me "file not found".

Is there a H81210F rooted version, tried to find it without success or the good link for the G one?
[G4 General] milan187:
Look at the first post. No root for MM.

The phone does have 6.0.1, why no emojis I have no idea, I don't really care for them but someone else might know how to get them.
[G4 General] bdasmith:
Look in settings on your phone....about phone software. It will say android 6.0 only.
[G4 General] milan187:
I know that but that does not tell the whole story as LG uses only x.x for version numbering. Even with 5.1.1 it was 5.1.

I don't think anyone uses 6.0, it's all 6.0.1
[G4 General] Faugly:
NickSVT-40, where did you get the H81220x KDZ?

I might be blind but im having a hard time finding it posted(besides that one where they force a downloader app on you). I need to update to Rogers firmware on this phone I just bought (is a Bell phone) to replace my old rogers one with a mangled screen.

Also, as a PSA I sniffed out the Bell KDZ link for H81220v with Wireshark for anyone who wants it:

http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FWB1JI6652TKABC934E50R4/H81220v_00_0621.kdz

seach here in XDA forum [KDZ][H812] New firmware Android 6.0 V20x [Security patch for 2016-07-01]

i am new so i cant post outside link

it works in my h812 no problems

---------- Post added at 01:24 AM ---------- Previous post was at 01:20 AM ----------

only problem is that WiFi calling and Video calling dosent work with my phone because it is originaly a Bell phone. Even with the Rogers latest firmware it still wont work

---------- Post added at 01:35 AM ---------- Previous post was at 01:24 AM ----------

What is the wireshark? i am going to reflash the Bell version into my G4 since i cant get the rogers services to work. seeing all those new buttons ( Wifi calling and Video calling ) and not beeing able to use them sucks i might as well go back to the Bell version
[G4 General] chriskwarren:
Hey guys.... Anyone keeping up with the "Unofficial bootloader unlock" thread? Folks are saying that if you dial *#*#244773825625#*#* and your sw sub is at 0, a bootloader unlock will be available soon. However, the thread says that if you are on US version and you took an ota update, then your sw sub is at 1 and not the unlock would t be available... I have a Bell phone, took an ota, and flashed Telus and I'm on a 0 count

Edit: Here is the thread http://xdaforums.com/showthread.php?t=3222737
[G4 General] Jok3r10:
Yeah i read up a little bit on that, and I think most of the Canadian Devices are in luck for the bootloader unlock. Even i took a few updates and my SW and Anti-rollback is at 0. So i guess now we wait.
[G4 General] Azure1203:
Yup. There didn't seem to be any Canadian users with the sw sub not at 0. Seems like we are pretty lucky.
[G4 General] Jok3r10:
I guess we are but still I m turning off the update thing. I don't want to risk it getting a new update lol.
[G4 General] Spudnubs:
Alright so a little update on this. Turns out that the DPI change I had made was the issue with gapps crashing. Now whenever I try to change the DPI it is not universal and only applies to the stock LG launcher. Status bar, other menus and appliances all remain the same now when I change the DPI.
[G4 General] nabbasi:
Hi may be off topic but does anyone have fido with volte working...
[G4 General] Jok3r10:
I have my dpi changed. I don't have these issues. What did you change u r dpi to?

I thought Volte is Rogers only.
[G4 General] nabbasi:
well fido does support Volte but not lg g4, I just dont understand that rogers support volte for lgg4 but fido not, its same phone and same network.
[G4 General] Touz604:
It says it's turned on on my phone.. Dunno if it's working though...
[G4 General] nabbasi:
Offically fido dont support on lg g4 volte even tho it is same firmware as rogers lgg4 just doesn't work its turn on mine too but doesnt work...
[G4 General] goofball2k:
Currently on the Telus 10G rooted system image.

As a Rogers customer, is there any danger going to the rooted 10H image (first using the stock 10H rogers image, then the rooted image) from the Telus image?
[G4 General] karendar:
G4 tweakbox support. :P
[G4 General] Spudnubs:
540. I've never had issues with DPI changes before. Maybe I will just have to use Per App DPI for now until I figure it out, but I have no clue why I am having so many issues.

No, it sounds like you are going to upgrade properly. Carrier doesn't matter and the only reason why I have the Rogers image separate is because other carrier's G4's do not have VoLTE support so if you were a Rogers user and wanted to take advantage of VoLTE, then you would need to flash a Rogers image or VoLTE would break. As long the phones build number lines up with the system images build number, then you should be good to go.
[G4 General] Jok3r10:
Yeah i have mine set to 540 as well and no issues. Could it be an

Xposed module that u r using, because you said even after a factory reset u still have the same issue.
[G4 General] goofball2k:
Thanks!! All done, and no issues that I can see. I was having an issue with the automatic brightness setting staying on after reboots with the Telus image but that appears to be working with Rogers, oddly. Never really known Rogers to really fix anything, lol :laugh:
[G4 General] Spudnubs:
Well the exact issue now is the DPI change isn't global, it's only being applied to my launcher now which is weird. System UI and other apps are unchanged. I may have to go through xposed and use Per App DPI but I found that to be a memory hog when I used to use it a year or so ago.
[G4 General] three-armsally:
Hello, first post for me I have a couple of questions

I'm with Fido so am I correct in assuming that everything that would apply to a Rogers phone should apply to mine?

I also came from a z3 which I never bothered rooting because apparently the root somehow managed to downgrade the quality of camera. Will rooting the g4 result in a decrease in camera performance as well?
[G4 General] Spudnubs:
Essentially, all of the Canadian LG G4 phones are identical with the exception of Rogers and their VoLTE services. If I am not mistaken, Fido is basically Rogers so they also utilize VoLTE. Now for you, the most important questions are what build is your device currently running and would VoLTE be something that you actually use or care about. If VoLTE is something you care about, use a rooted system image matching your EXACT BUILD NUMBER, however if VoLTE is a feature that you do not care for then you can go ahead and flash any other system image still matching your EXACT BUILD NUMBER at the possible cost of losing VoLTE functionality.

Let me know if you need any help. It's pretty late right now and if you do plan on doing any work on your device, make sure you read everything at least three times. Actually, it doesn't matter what time of day it is, reading and rereading is good practice.
[G4 General] Jok3r10:
Rooting the G4 does not decrease the camera quality. It just opens up more possibilities for example 60 fps video recording which is not available without root.
[G4 General] goofball2k:
Is this available through the stock camera app or some other camera app?

Thanks!
[G4 General] rytay:
I have an LG G4 on Virgin Mobile running MM (H81220v) but I can't seem to find the KDZ file to downgrade to LP (H81210v). Would I be able to use the Bell image to downgrade since they are all cross compatible? Or if anyone has it that would be great.
[G4 General] NickSVT-40:
Thank you very much Faugly for the Bell H81220v kdz. It worked out great, it got rid of my useless wifi calling feature and video calling button from my dial pad. it also got rid of the bloatware from Rogers. And it also seemed to have fixed my screen dimming problem i had with the auto brightness set to off. I had that problem when i flashed Rogers H81220e and didn't go away with H81220x.

Does anybody know if there is a way to flash the real 6.0.1 firmware with all the new Emoji's in the H812 without Root ?

I cant find anything anywhere and to much of a NooB to root my g4 lol
[G4 General] gordo1701e:
ok, paint me purple and call me crazy, but, is it not possible to use systemless root for the g4? I had it on my XT1563 and it ran MM 6.0.1..
[G4 General] Faugly:
Glad to helpNickSVT-40! Also thanks for pointing me in the right direction for the rogers one...just could not find it! Sounds like we should have just swapped phones :) Wireshark is a network analysis tool that I used to find the download URL that LG Bridge gets the firmware from.

Cheers,

Faugly
[G4 General] eboy_gb:
I think systemless root requires an unlocked bootloader...which the H812 doesn't have.

It's annoying being stuck on Lollipop to stay rooted when Nougat is just around the corner....
[G4 General] PDo27789:
I keep checking for a kdz file using the link in the OP, but still no luck. I've been entering my imei - is there a different site / method to find a kdz?

I'm on Bell mobility, so it should be out there somewhere.

I want to get back to lollipop so I can root n rom. If there's no kdz, am I SOL?

- - - - - - -

Never mind. Found a solution to go back to lollipop / root. Milan187's post, post 905 in this thread, describes how to go back.

That being said, I took a stroll through the development forum paying closer attention to version numbers. There doesn't appear to be anything for the 812 ...

Time for a new phone.
[G4 General] NickSVT-40:
My screen dimming problem came back with auto brightness off. I'm sure it's the proximity light sensor that is faulty or in the software. Because when i turn on the phone while blocking completely the proximity sensor it doesn't dim anymore. (knock knock doesn't work while sensor is blocked) but problem comes back if i wake up the phone without blocking the sensor. I have tried it many times and it's the same thing over and over.

Calibration in the hidden menu doesn't fix it, Lux and many other brightness apps iv'e tried don't fix the problem.

Does anybody know anything about this ? and also any new's yet about when and how to get 6.0.1 for H812 ?
[G4 General] djbigd01:
im having a problem with the hidden menu on my phone the bell variant the hidden menu is block or something i cant access it the reason i want to access it is i have replaced the screen on the phone and not the proximity sensor needs to be re-calibrated because the sensor shows a reading of something close to it so knock knock does not work and i cant use my phone while in a call because the screen stays black until the person hangs up i cant check voicemail's because the screen wont come back on to let me type my pin and im really getting annoyed so does anyone know how i can unlock the hidden menu

it is a bell variant

lg-h812

SW:h81220v
[G4 General] qu3becker:
I don't think LG released 6.0.1 on our devices and I don't understand why Rogers and Telus called the update like that. Only difference for our device would have been the emojis which I personally don't mind. Best Buy had the Nexus 6P, Galaxy 7s and G5 on sale on Fido. I was considering the 6P because I do miss root and unlocked bootloader a lot but the G4 is a still a great phone so it's hard to justify a new phone.

Anyway, I needed to vent a bit so sorry about that.
[G4 General] NickSVT-40:
Mine is also from Bell and the hidden menu works just dial *#546368#*812#
[G4 General] n01z:
I just picked up a Koodo G4 today.. It came with 6.0 already intalled, factory sealed with H81220u. GSMarena said it was "upgradable" to MM.. I read up on this too, I know NO ROOT for MM. I'm going to smash this phone if I can't even get root. I already compromised on the bootloader. I'm like wondering how difficult it would be to get an in person meeting with the higher-ups.. Not to try to convince them to be reasonable and help us. More to go breaking lots of heavy, shiny stuff that THEY probably like.

; )

My overclocked GS5 benchmarked way higher, too.. Super disappointed.. I sold it to get this.... >: /

At least Developer Options lets me set monochromacy to get a greyed out blackish theme.. Switching for video every time will be annoying.. Can we get some 1337 h4x0rz to destroy this device?? Come on.. It's a computer, if you can think it- it's possible. Has anyone set a bounty for this?? I'm going to be angry every day until I get root.. Then disappointed every day until the bootloader gets unlocked....
[G4 General] n01z:
Hmmm.. So a downgrade is possible.. I'll give it a go..
