I was on version H81010h...So went for stock .tot... I have researched a bit and I think the radio of my phone is disabled..Is there any way I can enable it?

---------- Post added at 11:04 PM ---------- Previous post was at 10:55 PM ----------

using this code 2945#*810# when I check for network lock...it says "This phone is permanently locked and cannot be unlocked." :(:(:(

This is my only phone...
[AT&T LG G4] hyelton:
Hmmmmm that happened to the previous person. So you where using this phone before with your sim correct? And it was working.
[AT&T LG G4] s.a.maan:
yes it was working fine...
[AT&T LG G4] hyelton:
Did you try reflashing?
[AT&T LG G4] s.a.maan:
planning to do so...
[AT&T LG G4] hyelton:
Update when you do
[AT&T LG G4] s.a.maan:
I went for MM update I thought may be upgrading to MM will solve the problem but no use...Now I am trying to flash Lolipop but LG Flash tool gives download fail error just after start of the process...:(:(:(:(

AT&amp;T H810 Back to Stock Guide (TOT Method)

First you cannot use flash tool to flash a device when it has MM you use LGUP.

But

If you upgraded to latest

DONT. Do that... you'll brick your device. You cannot downgrade from 'MM for that model.
[AT&T LG G4] s.a.maan:
Already done that...Any thing I can do now?:(:(:(
[AT&T LG G4] s.a.maan:
[MENTION=2607037]hyelton[/MENTION] please help me....:(:(:(
[AT&T LG G4] hyelton:
Sorry somehow missed your reply earlier,

If you did and your phone does not boot, sadly no you cannot. Bricked is bricked. Would need a board replacement or warrantied.
[AT&T LG G4] s.a.maan:
No it gets booted... everything is working just fine except for the network signals...I started phone without sim and it says there is no sim but when I insert sim back and boot just network signals dont come up...If I try to make a call.. It says to turn off airplane mode first..Although it is already off...
[AT&T LG G4] hyelton:
Okay good. Thankfully it did not flash. Where did you buy your phone? This seems like it may have something to do with the phone had been tampered with in the past.
[AT&T LG G4] s.a.maan:
Bought it from a shop at very cheap rate in Pakistan...So what should I do now?
[AT&T LG G4] hyelton:
Only choice is to return it or warranty it.
[AT&T LG G4] s.a.maan:
[MENTION=2607037]hyelton[/MENTION] Can't do that :( radio of my phone is off. See the screenshot
[AT&T LG G4] hyelton:
Can't do what? That's the point of why you would need to return it or warranty it..
[AT&T LG G4] s.a.maan:
Can't return and can't warranty it...If there is any workaround please guide
[AT&T LG G4] hyelton:
As I've stated there is no fix for this. As it seems like the seller had tampered with the device in some way
[AT&T LG G4] s.a.maan:
Can I flash 1010o using LGUP?
[AT&T LG G4] hyelton:
That's not going to fix the current problem your having. And if you updated to the latest MM you can no longer downgrade
[AT&T LG G4] s.a.maan:
[MENTION=2607037]hyelton[/MENTION] I successfully downgraded to 5.1 10o Now can u please guide me to some thread with root method for LG g4 h810. And is it possible to further downgrade to 10g from 10o?
[AT&T LG G4] hyelton:
1. This is a stock only thread so no clue on root. Never rooted that model..

2. No as 10o is the lowest and only available tot file for that model.

3. Also remember be careful once your on latest MM you can no longer downgrade.
[AT&T LG G4] s.a.maan:
Is there any thread that will guide how to root a custom rom?
[AT&T LG G4] hyelton:
A custom rom would already be rooted, but to root and flash custom rom guides would be in the general section if there is.

So i might have flashed a broken file onto my G4 and now its completely unresponsive, but when i connect it to my laptop it still shows up. However using the TOT method i get an error at 8 sec and IMEI and PID show "NULL"... What's all this about?
[AT&T LG G4] hyelton:
What do you mean by broken file? You need to explain. Via recovery? What did you flash? Or did you try downgrading? If you tried downgrading and you where on the latest firmware that's why, you cannot do that.

[AT&T LG G4] hyelton:
Huh? That link has nothing to do with an LG phone. That tool is for low end devices with mediatek chips.

There's no physical way to roll back past an antirollback. And doing so results in a non fixable brick.

please help, my mobile is in bootloop , i was using prerooted system rom h81010o , i wanted to go back to stock rom , so i used lgup and stock LGH810AT-00-V10o-ATT-US-SEP-10-2015-ARB02+0_User_Secure file, choosed refurbish and flashed it , but now i can only see blinking lights ,LG LOGO , please tell me what should i do now
[AT&T LG G4] hyelton:
Did you try reflashing it again or trying to use the button combo to perform a factory reset?

Also depends on the boot loop remember bootlooping on the G4 is common for hardware failure.
[AT&T LG G4] Amit2310:
yes , i tried flashing it thrice, also did factory erase, it didnt worked, so i followed one post in xda which said to flash with h810pr for soft bricked device, and it hard bricked my device

and as far as i got to know from google is that i lost the device already now lol. its just detecting as qualcomm device in device manager, it can be recovered via emmc flashing and that emmc file is nowhere in google

i found this link , its for hard bricked LG devices

my G4 is getting detected as qualcomm 9008 device

i am gonna try this
[AT&T LG G4] hyelton:
You Can try that. But I don't think it works with the G4. And never flash wrong model firmware. It's most likely fully dead for sure :(. Also Emmc flashing requires an physical hardware device which is not cheap.
[AT&T LG G4] Amit2310:
no option for g4 in that app, its not detecting mobile , no luck , stupid LG , Samsung devices are better ,atleast it never got hard bricked
[AT&T LG G4] hyelton:
Samsung devices do get hard bricked when you do something wrong like flashing wrong model firmware. And usually a lot harder to recover at times.
[AT&T LG G4] Amit2310:
I flashed wrong modem in s5 many times , it starts working after flashing with right modem

I guess its not hard brick then

Lg g4 H81010i assistance

hi, I have an lg g4 on software version H81010i so i want to upgrade it to H81010o by flashing this stock firmware. my device is not rooted and it is not upgrading OTA. has anyone with H81010i tried this solution? if it is working will i be able to upgrade to MM OTA after this? please help me. I dont want to do anything now by fear of bricking the device, Thanks.
[AT&T LG G4] hyelton:
You can flash 10o. But that won't fix your OTA update issue. I'm going to assume your not using the device on AT&T? You must have an active AT&T sim or AT&T prepaid sim to be able to OTA update with AT&T devices.
[AT&T LG G4] daywalker9:
yeah i dont have at&t sim, so after flashing this what is the most suitable method of goin to mm ?
[AT&T LG G4] hyelton:
The only method is OTA update sadly with the AT&T model.
[AT&T LG G4] daywalker9:
so should i make a backup before flashing this software? or just use it as new?

I flashed it successfully. at first it gave some error. then i disconnect my internet during whole process. and it worked without any problem. maybe you should put that in tutorial. Thanks for help. Now i will flash marshmallow.
[AT&T LG G4] hyelton:
Depends on what you mean by error. Some errors are not actually errors. But disconnecting from the internet wouldn't change anything as nothing uses the internet.

Glad you got it flashed and good luck getting to MM :).
[AT&T LG G4] biggstreet:
did this tutorial work with h81010b ?
[AT&T LG G4] hyelton:
10b is your firmware version not model number. It works with all LG devices.

Then you must of been of been running MM 6.0 which you cannot use flashtools for.

Why couldn't you use google services before?

This does not relock the phone unless the device was tampered with or unlocked in a manner that was not legitimate.

[AT&T LG G4] hyelton:
AT&amp;T H810 Back to Stock Guide (TOT Method)

Use the LGUP / generic dll file and hope that it works.

What firmware do you currently have on it?
[AT&T LG G4] simonwhiteuk:
Yes I tried to do that, using the LGUP_8974.dll, but no success. It even displays 8974 at the top of the program as the model, but I still get the error.

My phone has H81510b firmware, my phone is H810, and I'm trying H81010o firmware from ATT.

But on the flash tool, it says my phone is LS991, which is even more strange.
[AT&T LG G4] hyelton:
I'd return it. Not sure if your the same person I spoke to a few days ago but he had the exact same issue. Flashing the device may end up with a bricked device as it's most likely a refurbished model. It's probably a LS991 running a custom modified firmware so it will work with SIM cards. As it's not meant to other than Sprint.

Only real way to know what model is to take apart the phone.
[AT&T LG G4] fim438:
Hi, i flash my h810 this method on 10o, then on 20n. I have a problems:

AT&amp;T H810 Back to Stock Guide (TOT Method)

You can return to 10o if your still on 20n as someone a few pages back did. But remember downgrading is risky with that model. But if newer than 20n there's antiroll back and which you cannot. When you flashed you choose refurbish correct?
[AT&T LG G4] hyelton:
Sounds like something is up with your computer if you can't simply install the drivers for it. I'd suggest trying another PC if you can.
[AT&T LG G4] fim438:
Thanks for answer, i'm still on 20n. Whether I must to use a LG Flash Tool or LGUP? If LGUP, how to choose correct refurbish. I tried use lg flash tool, but i got error on third second.
[AT&T LG G4] hyelton:
You use lgup when your running MM. Plus it's more safe as if there's antirollback it will stop you while flash tool won't.

On lgup you just choose refurbish ans choose the firmware file.
[AT&T LG G4] fim438:

I am using the LGFlashTool_1.8.1 and the LGUP_8974.dll. Is this not the right combination?
[AT&T LG G4] hyelton:

If you didn't do anything to cause that, that's a hardware failure. Only solution is warranty. Remember this is a very common problem with all G4's

Explain? Why was you flashing? Where you attempting to downgrade? If so was it from latest MM? You would need to use LGUP. Also if you where running the latest version of MM you may have tripped antirollback and bricked the device.

Wait where are you getting the 21y firmware???

When using lgup and getting unknown error usually means the correct dll files where not installed along with it. Just turn On USB debugging mode and have the phone booted into android and it should detect it.

[AT&T LG G4] hyelton:
Perform a factory reset? Strange another member said it fixed theres.
[AT&T LG G4] ry7669:
I assume a factory reset wouldn't resolve it, since I had flashed the TOT and then restored the rooted H810o img file afterwards. It doesn't seem as bad as it was before but it still appears.

Can you recommend a method to avoid wiping but allowing to upgrade, if there is one?

A couple of things..

1. I had never connected the phone to my pc before so the 1st time I tried to upgrade it failed because the mtb part of the drivers wasn't correctly installed. So after installing the drivers it seems to be necessary to connect the phone in normal mode first, to fully install the drivers.

2. the 1st time I ran LgFlashTool a dialog popped up with 4 options, something about Korea, China, test; I didn't know what to pick so I just left it on Korea.
