I have a feeling that these G4s are a 'flakey' bunch (ie. screen coating issues, missed taps and swipes, wifi issues, etc.)

If you want root, obviously stick to 5.1 until someone does something with 6.0.

However, my device is one of the flakey ones; at the beginning, I had lots of missed taps, and my swipes were being registered as taps, etc. It was awful. Almost gave up on the phone. Then, I tried flashing a Telus update on my Bell G4 (Bell was lagging behind on the update) and that made the taps much better. The latest update on Bell which I flashed made the taps much better, and improved swiping a fair bit. But my G4 still did not have a premium feel as far as using it day to day....a missed tap occasionally, tap to turn on the screen was inconsistent, and scrolling and swiping was skittish.

The MM update seems to have eliminated all the performance issues on my G4. No missed taps in a few days, tap to turn on the screen is now flawless, and scrolling is now 'butter smooth.' For the first time since I got my G4, I can say that my phone is behaving like a flagship device. I would sometimes lose my wifi connection if I was streaming a youtube video for any length of time, etc. I have not seen this yet, but have not tested enough. My battery life seems to be no different, so far.

A problem that is still present is the crappy auto brightness. Too low before MM, and too low now still (and I dare say they made it worse).

I would feel pretty good about this phone right now if I did not have a phone in the dreaded 505-506 batch made last spring. I have avoided rooting under 5.1 as I have been worried about an RMA, and I didn't want to have LG try to use that as an excuse to avoid a warranty claim (in case they would be able to tell).

So I would say that if you must have root, then as always you should wait a while. If your phone is working great for you on 5.1, then, as always, there is no harm in letting a bunch of others try the new OS out for you, and grab an update after the rest of us have tried the new OS for a bit. This is XDA, and there is no shame in holding out for a root method, especially if your phone is working great already. One of the oldest lessons you learn if you enjoy root is to avoid updates until other people have figured out the root/bootloader situation.

If your phone has been flakey with taps and scrolling, then my experience says that MM is well-worth it though. Don't be dissuaded by blanket statements that MM is crap, etc. because I believe that each user can decide that for themselves. For me, it was a great update.

How would I get a H815 in Canada? Do carriers let me choose, or am I forced to find a seller on Amazon/Ebay?

Also, I'd like to thank the guys poking around H812 Marshmallow :svetius:
[G4 General] qu3becker:
I wish the carriers let us choose. Haha

Nah, you gotta buy online. H815 is the international/European model.

Side note, Marshmallow update on my device feels snappier and battery life flatlines on idle now, it was draining too much before. Very happy although I do miss having root permission mostly for dual window.
[G4 General] goofball2k:
NCIX sells the H815.

What do you mean by "reinstall my software"? You mean the OS or some apps?

You want to reset your device to stock condition?

You want to update it to the latest version of Android (6.0)?

Does your device works normally right now?
[G4 General] sukham2495:

Software version latest I don't know because when I switch on my mobile it shows mini os and than factory reset status 2:confused::confused:
[G4 General] Spudnubs:
Are you looking to upgrade to Marshmallow? I don't know what carrier you are on, but that is a Rogers KDZ.

This is a pretty decent guide on how to flash KDZs, although I do not think it is the best. I've experienced issues with it and Marshmallow, but it is the only program I've had experience with.

Other users have reported better success using LGup, so that may be a better option for you.

[G4 General] kwarwick:
Anyone having bluetooth problems after upgrading to MM (Rogers release in my case)? I have two bluetooth devices that are experiencing problems. One is a Mi Band that won't pair and the other is a Soundpeats QY7 headset that will pair but won't play music without multiple attempts at turning bluetooth off and back on and reconnecting with the headset. The Mi Band problem I've encountered before on a Nexus 5 when it got upgraded to 6.0 but was fixed with 6.0.1 update. Hopefully 6.0.1 update will be coming to the G4 too.
[G4 General] bitemark01:
I posted a couple of pages back that with Android 6.0 you are now required by Google to turn on your Location Settings in order to have a bluetooth device pair and sync (major reason for me rolling back). If you look up a couple of posts, another guy suggests downloading a location spoofer, though I don't know if using that means you'd still have to leave Location Settings on or off.

Maybe that's your issue? Try turning on Location Settings and see if it will pair. My Garmin Vivosmart refused to unless I did in 6.0.
[G4 General] kwarwick:
I've got Location turned on with Mode: High accuracy (GPS and network).
[G4 General] anterus:
Which version of the Radio (baseband) do we have on MM? That may be the only reason to upgrade. 5.1 has MPSS.BO.2.5.c3-00070-M8992FAAAANAZM-1, is it the same for MM?
[G4 General] mb_guy:
Nope

MPSS.BO.2.5.c3-00109-M8992FAAAANAZM-1 for Rogers
[G4 General] karendar:
Don't have my phone with me, but I'm pretty sure the baseband was updated. I'm getting LTE signal in areas I didn't get before.

Fido (Roger) H81210H to H81210N then MM

Hi, I have a rooted H812 G4 Fido (Roger) with H81210H with Xposed right now. I heard that if I upgrade the system to H81210H to H81210N, then I will lose my previous root. And I saw the H81210N can be rooted. If I upgrade to H81210N, will I lose the Xposed too? or I just flash the MM (H81220E)? my system update center only shows H81210N.
[G4 General] Spudnubs:
If you upgrade any software, you will lose root and xposed.

If you upgrade to H81210N you can just reinject/flash root and flashfire xposed back onto the device.

If you upgrade to Marshmallow H81220E you will lose root and xposed permanently.
[G4 General] cskzhi:
Thx for the answer, seems like I can upgrade to H81210N then reflash the root and xposed back. Do I use system software update to H81210N or use PC to flash rooted H81210N directly? Will lose all my documents after update?
[G4 General] stevenma188:
Any idea when we will get a 20E rooted image?
[G4 General] goofball2k:
You have to get to 10N before you can flash the 10N rooted image. You can't be on 10H and then flash 10N rooted image.

You won't lose anything after the update. At least, I did the update to 10o and did not lose anything. Then I flashed the rooted 10o and xposed using flashfire again.
[G4 General] jainanshal:
If by 'system software update' you mean taking OTA, you won't be able to update to 10n via OTA if you're on 10h rooted. Also, as mentioned above, you cannot flash rooted 10n from 10h.

Best way is to use LG Bridge with rooted 10h to update to 10n, you will lose root but all your data will be intact, even SuperSU will be remain installed (ofc without root). It is however still recommended to keep a backup just in case, coz s**t happens.
[G4 General] eboy_gb:
Sorry if this is a dumb question (the info I'm looking for is buried in this pages of this thread).

What's latest version of Lollipop (ie build letter - E,F,G,H..etc.) that I can flash on my Bell G4? (whether it be from Bell or Telus)

Thanks guys.
[G4 General] s0ulreaver:
You can get H81210E_00 from http://devtester.ro/projects/lg-firmwares/country.php?country=Canada
[G4 General] eboy_gb:
Thank you! but I thought Telus/Bell got up to 10-N or 10-O before Christmas? Unless my memory is off...
[G4 General] s0ulreaver:
True, I did, as well. But the other updates were OTAs and not full updates :)
[G4 General] eboy_gb:
Oh gotcha.

I'm on 10G (for Telus I believe) - which one fixes stage fright?
[G4 General] s0ulreaver:
IIRC vE was still testing positive for one of the vulnerabilities but vO was imune.

---------- Post added at 04:25 AM ---------- Previous post was at 04:12 AM ----------

I have two questions for my fellow G4 users:

- did you guys disable the MLT option in the service menu? many say it is a 'big brother' option and you can get more free memory memory once you disable it. I disabled it on my G4.

- is the Fast Dormancy option enabled by default on the G4? On my Bell G4 I can't say if it is or not.

To see the 2 options, go in dialer and dial *#546368#*812#

-> Field Test -> Modem Settings -> PDP Setting -> Set LG FastDormancy

-> SVC Menu -> LDB -> LDB Setting - uncheck Enable
[G4 General] Spudnubs:
Yes this has been posted before.

I am not sure about fast dormancy
[G4 General] chriskwarren:
I moved up from a Telus rom that I flashed around Sept, to the O update via LG bridge....LG bridge even knew to flash the Bell rom and not a version of the Telus rom I was on.

[G4 General] Spudnubs:
If anyone has any stock KDZ's that you cannot download from from Dev Tester and I have not added to the OP, throw them my way and I will host them and add them to the OP for others to use.

Thanks guys.
[G4 General] cskzhi:
Yeah, I tried to update through OTA and the system said it won't be update on rooting device. So the only option is to use LG Bridge to upgrade, Will I lose my data from LG Bridge update?

PS: The LG Bridge shows the latest version is H81220E, how could I flash 10N to my phone through LG Bridge?
[G4 General] Spudnubs:
You will not lose your data on LG Bridge or flashing KDZ's unless you physically tell it to do so by choosing the option.

If you want to flash H81210N to your device, do it with the LG Flash tool in the original post. That is the program that I am most familiar with. All you need to do is run it, you should already have proper drivers from LG Bridge, load the KDZ into the flash tool, choose English for the language (unless you can read korean), put your phone into download mode by removing the battery, plugging the battery back in, plugging the USB into your phone and computer and holding volume up (dont quote me on this, it might be down, I am typing this from memory), and flashing the KDZ.
[G4 General] cskzhi:
Yeah, and I actually didn't find the stock KDZ for H81210N, neither the link below the Stock KDZ, only 10H and 20E on the Canadian Guide thread. When will the 20E can be rooted? if I use LG Flash tool, will I lose my data?
[G4 General] Spudnubs:
Again, I'll reiterate, you will NOT LOSE DATA if you flash a KDZ to your device unless you explicitly tell whichever flash tool you decide to use to wipe your device and do a factory install. No, LG Flash Tool will not erase your data unless you tell it to. Same goes for the other KDZ flashing methods.

After a quick Google, I was able to turn this thread up:

http://xdaforums.com/g4/general/h812-canadian-h812-n-update-kdz-t3282791

I get very busy and possibly overlooked uploading that specific H81210N stock KDZ, I was probably busy/worried about rooted images first, so I will upload that to my androidfilehost and update the OP.

I wouldn't even think about the possibility of Marshmallow being rootable as it is currently unattainable.
[G4 General] cskzhi:
Got it. Thx for the detailed reply, the stock H81210N in link is for Telus/Wind. My G4 is Fido (Roger). Maybe I will stop here...:crying:
[G4 General] Spudnubs:
The stock H81210H in the OP is the most updated Rogers firmware that I am aware of. I don't think that Roger's has put out an update after that, but I could be mistaken. I run a Telus device.

Side note, I ran that exact Rogers H81210H Rogers image for about 3 months before updating to Marshmallow when it came out, it is perfectly fine to use. All of these updates past ~E are basically identical.
[G4 General] anterus:
Indeed, radio wasn't upgraded within any v10 changes. All else - you shouldn't care much about. Sounds like it is also the same radio for v20, just the build number incremented - probably to be built better with MM
[G4 General] gundamboy:
Is stock the only thing available for our canadian devices right now? :(
[G4 General] Spudnubs:
Since our bootloader is locked, then yes.

Since we are unable to root Marshmallow, also yes.

Best just to stick with Lollipop for the time being.

[G4 General] Spudnubs:
This is the first I am hearing of this.

What exactly is the issue?
[G4 General] bitemark01:
Just as an FYI, Rogers does have a H81210n update, that is only an update on top of the H81210h update (it's 87.5 megs). I've was able to download it OTA on my phone, though I haven't updated it yet because I thought I would poke around and try to extract it (no luck so far). Using LG Bridge they try to push 6.0 and skip over this.

That being said, I've been using the H update for the past few days and seems to be pretty solid -- I'm not even getting the camera issue I was getting after the N update.
[G4 General] bdithug:

I tried taking out the battery and inserting it back in after 5 minutes, Same issue.
[G4 General] Jason123420:
Yeah happened to me. I was using mine tho... Phone froze.. Then the boot loop started. Doesn't let you factory reset, flashing KDZ doesn't help either. Had to give mine to Bell to send to LG.. Took like 6 business days to get it back
[G4 General] Spudnubs:
So weird. Was the device modified in any way? Root or xposed?

Did you get the exact same device back, or did they give you a new one? Did you try to use multiple different flash methods for KDZ's?
[G4 General] Jason123420:
I got the same device back. I restored it with LG bridge also. it booted up for about 20 seconds and then shut off... its definitely some sort of hardware issue. Also my phone was purchased in August with serial number starting 506. Bell in Grande Prairie Alberta said it was the first one they got back for this reason. At the time it wasn't rooted and didn't have the xposed module flashed..
[G4 General] Spudnubs:
Interesting, thanks for sharing. Do you know what they did to get it back to working?

[G4 General] Jok3r10:
We can never say anything about the updates. It all depends on when LG decides to release it and also when the carriers decide to push it to our devices. Although I think that if LG pushes an update the international version would be the first to get it(i m not soo sure).

A question for you experts out there:

Someone just offered me the H815T for a great price. I'm on Rogers. Should I buy it? Will it have VoLTE? Does it support LTE-A? I see that it has all the LTE bands that the H812 has, except for Band 2 (1900) and Band 12 (700b).

I've tried http://www.willmyphonework.net/ but I've found that its information is often not accurate!
[G4 General] Azure1203:
Well, USB tethering works for me through PDA Net, but I can't get the Wifi Hotspot to work through FoxFi. Should I do a factory reset? I tried switching APNs, but nothing helps. I'm on MTS.

I think it has something to do with my built in Wifi Hotspot app always trying to take over. When I use PDA Net USB tethering it works without the native USB tethering turned on, but when I use PDA Net Wifi Tethering it activates the native Wifi Tethering, which doesn't work.

Is it possible to modify the default camera app so that it records 60 fps instead of the default 30 fps? I know there's a modification, but I believe you need to install the zip through twrp. Anyone think you can just use flashfire instead since we have the locked bootloader issue?
[G4 General] Spudnubs:
I don't know what mod you are talking about, but I can tell you this:

Essentially, recoveries are doing when they flash .zip files are taking the files that are compressed and moving them into their proper spots on your phone so if you decompress the zip and locate where the files go on your device, then you should be able to place the files from the zip into their respective spots on the device.

Does that make sense? Always make a back up of the files you are replacing and remember to check the permissions of the files that you are copying over as they are most likely not going to match.

Recap:

Decompress the .zip

Locate where the files go on the device

Back up the originals

Copy over the new files

Check permissions

Good luck!
[G4 General] goofball2k:
Yes you can use flashfire or you can copy the 2 files into the proper directories, set the permissions manually, reboot, and you're good.

Also, 10H is basically the exact same as 10N. All this fuss to have the newest stuff is ridiculous. Are you experiencing any issues running 10H?
