nah im 100% sure i flashed correct firmware.... check out the tot flashing method here. http://xdaforums.com/tmobile-lg-g3/general/firmware-t-mobile-lg-g3-t2818667 he specifilly stated it and it fixed all my issues....u maybe could ask him what the difference is.
[LG G Flex 2] hyelton:
If you have a H950 you shouldn't be flashing the H950PR firmware. That would be the reason why.
[LG G Flex 2] Yania1991:
The exact reason is that I'm tried to install flash-mods without rootedimage.img in the internal memory, which is necessary for normal installation and for recovering in case something will go wrong. I forget that I deleted it.

Next time, I will be paying much more attention to what I'm doing with my phone:)

Thanks again!
[LG G Flex 2] maxmotos:
so did anyone solve the issue with "prepareAfterDload" is it a driver issue?
[LG G Flex 2] hyelton:
That doesn't sound like a driver issue. If it was a driver issue it would detect the phone or attempt to flash. Explain a little more? Where do you get that error ? Screenshot?
[LG G Flex 2] maxmotos:
I have a device which im trying to flash btu stops at 4% but shows a message saying "prepareAfterdownload" then stops tried several computers.

I've honestly never seen that error before

yup same here seems a bit strange.
[LG G Flex 2] jwhite326:
I was sort of confused by the instructions at the beginning of this thread. Is this supposed to remove root and reinstall the stock firmware? At least for me -- I have an AT&T H950 -- it didn't work. I was able to reinstall the TOT file provided, but I don't think it is actually a stock AT&T rom. It's missing several AT&T bloatware apps (not that I mind), and it's already rooted. But because of this, AT&T won't let me download OTA updates, as it says the phone is "suspected of rooting." I also tried it with the LGUP app. Again, I was able to flash the TOT file, but the phone was still rooted. I thus suspect that the issue is with the TOT file.

Anyway, if anybody's in this same situation -- you have a rooted AT&T Flex 2 and want to go back to stock so you can receive over the air updates -- you can try the other thread with the LG Tool: http://xdaforums.com/g-flex2/genera...-stock-tool-h950-t3171550/page23#post67664637

That worked for me. I was finally able to get my phone back to stock, and I'm now downloading OTA updates as we speak.
[LG G Flex 2] hyelton:
Its most likely a prerooted TOT. Which is the only tot available for that model. That link is very helpful but its still not a factory tool, it restores the images for the factory firmware.
[LG G Flex 2] Behkho:
Hi. I had rooted my G Flex 2 with ZV9 but had trouble activating it on Ringplus. They said no flashing or such, so I tried getting stock rom following http://xdaforums.com/g-flex2/general/guide-lg-g-flex-2-stock-firmware-to-t3037593.

It failed at 85% when my phone was in Mini OS 3.1. Now all I can do is reboot by holding power and volume down buttons. It goes back to Mini OS. Any suggestions?
[LG G Flex 2] hyelton:
[Guide] LG G Flex 2 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

You have to press the on screen button that says reset/reboot. Remember it failing after 80% is normal. Rest is rebooting.

Also the link you provided is to this extract thread :)
[LG G Flex 2] paul618:
hi when i go to download the dll file for a uk device its a kdz file and not a dll file
[LG G Flex 2] hyelton:
Huh?? If your downloading a kdz you don't need a dll file..
[LG G Flex 2] jwhite326:
Okay. So I totally get that you're doing everybody here a favor and are not getting paid for your efforts.

But still, maybe the title of this thread should be updated, as it's a little misleading. It says "RETURN TO STOCK TOT METHOD!, AT&T, T-Mobile, Sprint, Verizon . . . "

I followed the instructions verbatim several times, yet kept getting the same result: a modded, pre-rooted image. I figured that I was doing something wrong, and that I wasn't flashing the file correctly. But I'm pretty sure the issue is with the AT&T file that's provided: it's NOT stock as the title suggests, but is rather a modded, pre-rooted file. In the end, I wasted several hours repeating this method quite a few times.

Again, I don't blame you for anything, and I think you're doing the community a great service. But if you read through people's comments, I think you'll find that I'm not the only person who was misled by the instructions. Now that we've identified that there's an issue with the file, I think it would be appropriate to note it. It would only take a minute or two to do so, and it might save other users a lot of time and frustration.

Otherwise, seriously, I appreciate the help and keep up the good work.

[Guide] LG G Flex 2 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

Thanks :)

it's only the AT&T model tot that is rooted. The rest of the models are factory stock. The thing is the tot is stock just rooted but it's the only tot for that model in case it's ever needed. Sadly AT&T has always been tot if it was like the non us models we would have a factory kdz.

Also the title of the thread doesn't include any specific model. At the top of the thread it does not but the title itself.
[LG G Flex 2] jwhite326:
Okay. So why not mention that in the original post? It seems like a pretty important "detail" to leave out. The title as much as states that users can follow the instructions in this post to return their AT&T phone to "stock." In reality, they cannot.

---------- Post added at 08:32 PM ---------- Previous post was at 08:30 PM ----------

Also, as I mentioned in my earlier post, the file's not actually "stock" either. It's missing several -- granted, worthless -- AT&T bloatware apps. But still, it's not stock, and AT&T will not provide OTA updates because of it.
[LG G Flex 2] hyelton:
I changed my post a little which you may not had seen sorry about that.

The OP has so much info it will still get overlooked by some users even though it being in plain text. But I did make a change at the top of the OP.
[LG G Flex 2] Behkho:
Heh, yeah. Silly me. Thanks.

I got out, and software info shows ZV8_01. But for some reason, it's still rooted and won't activate Ringplus. Doesn't seem to look for update to ZV9 through Wifi either. Am I missing something?
[LG G Flex 2] hyelton:
[Guide] LG G Flex 2 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

Rooted or not shouldn't matter for ring plus it should still work. Does ring plus use an app like FreedomPop for its texts and calls? If it's rooted it won't update that's why it won't update.

You also activated it ring plus with your imei? Etc correct? If so you've already went to settings and selected update prl , and update profile?
[LG G Flex 2] Behkho:
It goes through hands free activation w/o a problem but fails at PRL update. I checked IMEI through their site, so I 'm pretty sure it's correctly set. Someone on Ting site mentions failing PRL due to bad SIM, so I'm wondering if that's the case.

Shouldn't Android try to update to ZV9 since I'm currently on ZV8 from the link you provided?

Ringplus tells me to enter ##MSL#, but when I do so, with pounds and MSL number they gave me w/o pressing anything after last #, nothing happens.

[Guide] LG G Flex 2 Stock Firmware (Go Back to Stock) KDZ &amp; TOT Method

And do you have the Sprint model? The LS one? I'd suggest you go and relook at the instructions.. I clearly stated that Sprint models cannot be downgraded and in which you must of downgraded. If you had a newer firmware and you flashed ZV5 then you downgraded. So there's no false info. Remember everything and anything you do here is your own risk and is at not ones fault.
[LG G Flex 2] sirwanesmail:
I

I was on zv 5 already and by the way the .dll file you provided was for sd 800 and by using that file you completley destroy your phone all i wanted was to get rid of root and go to stock zv5 but your false information and lack of info did wahat happened and now that instead of saying air please help me will help me?
[LG G Flex 2] hyelton:
The dll file doesn't play a role in bricking a phone... If the dll file is incorrect you cannot flash at all. It's the firmware file that plays a roll.

There's no false info in my OP.. Also if you look at who your quoting I'm not the one who said what firmware to flash. But either or it's no ones fault.

If you downgraded a sprint model it's fully bricked there's no way around it besides a motherboard replacement.
[LG G Flex 2] outlogic:
Tried to flash my LS996 (with ZV7). When I use the UPGRADE DL option, it flashes 100%, but I get the blue screen with the "Factory Reset Status 2". When I use the BOARD DL option, I only get to Mini OS and it fllashes 85%. Tried multiple times. But after a factory reset I was able to find the Normal Reboot option in the Mini OS after pressing Vol Up and Power buttons. Now the only problem I have is that I can't pass the Google Account Recovery. Tried to change my password to no avail. But may be the password changed caused the 72 hour lockout.
[LG G Flex 2] outlogic:
How did you bypass the verification screen?
[LG G Flex 2] outlogic:
deleted
[LG G Flex 2] hyelton:
First of all anything after 80% flashing is DONE. it's going to almost always fail after that. That's normal.. About the Google account recovery you must use correct info there's no way around it. If you entered it wrong several times and reset your password you need to wait the required time before trying again.
[LG G Flex 2] outlogic:
Waited for about 2 days, but eventually I managed to log in. GSM works fine on LS996 without any additional manipulations, although handsfree activation closes with some error. Thank a lot!!!
[LG G Flex 2] staticx1:
please advise... can I go from AT&T 11z rooted to 5.1.1PR?
[LG G Flex 2] hyelton:
And is your phone an H950PR? That firmware is not for the AT&T model..
[LG G Flex 2] staticx1:
got my phone with att 5.0.1,

flashed 5.1.1PR

Flashed ATT 5.1.1 11Z Rooted

now I wanna go back to 5.1.1PR

is it possible?
[LG G Flex 2] nacho113:
NO, cannot be done.

The AT&T rom has an anti-rollback feature, flashing anything other than an AT&T update to a higher version will cause the phone to be bricked.
[LG G Flex 2] staticx1:
Even if the rom is rooted?
[LG G Flex 2] hyelton:
Root has nothing to do with flashing stock firmwares since its stock.
[LG G Flex 2] staticx1:
So there's nothing I can do now..? Married with AT&T?... [emoji33]
[LG G Flex 2] hyelton:
Well your phone is an AT&T device. It's not even supposed to be flashed with PR firmware. But yes your stuck on your firmware and or future updates for the AT&T model.
[LG G Flex 2] nacho113:
I was in the same boat as you; couldn't get the AT&T 5.01 to 5.11 update since I wasn't an AT&T customer, jumped in early when the 5.11PR apk was posted (really liked it but it bothered me that it didn't show LTE), saw the OP's tot for stock AT&T 5.11 and have been running since Christmas time without issues. Again, it sort of bothered me how it had all the Chinese stuff during boot up after flashing this tot and the fact that it was already rooted means no OTA updates. So I used the method found here to get rid of root and restore full AT&T system setup http://xdaforums.com/g-flex2/general/p-restore-recovery-to-stock-tool-h950-t3171550

There was a recent update from AT&T that I managed to get OTA using an AT&T Go sim card and a $2/day plan. They updated 5.11 to rev 12d, so I'm hoping this is the precursor for the Marshmallow rollout.

FYI: If you go back to the original thread about using the 5.11PR kdz to update, there's lots of warnings (and horror stories) about people bricking their phone by trying to flash 5.11PR back over the AT&T 5.11

I WANT TO GO BACK STOCK 5.1.1. I HAVE DONE it ONE TIME ALREADY IN MY G FLEX 2 H950.

After installing xposed framework, when I want to go back again to 5.1.1 using this method,.I have got an error " Failed previous load"..attached. please help.

[LG G Flex 2] hyelton:
That's usually a computer or tot file error. But remember on 5.1.1 you may brick if downgrading /flashing older firmware.

i upgraded my h950 from 5.0.1 to 5.1.1 using this guide almost 4 days ago .

2 days ago my h950 stopped to boot up at all.

It just keeps bootlooping on the LG screen .turns off and again LG.

When I try to use it plugged in ,it works normally .Also my phone remains always really hot .

I think it is a hardware issue.maybe with the battery?Guess only ?

Anyone here has a idea/solution ?I am currently outside us .
[LG G Flex 2] hyelton:
What firmware did you flash to get 5.1.1? From the OP? You didn't flash the PR version correct?

But yes sounds like a hardware issue. First guess would be change battery. But there's no specific I reason or clue why it's doing that other than hardware issue.
[LG G Flex 2] parmar.saab:
I have an AT&T H950 that I've been running on the rooted 5.1.1 H950PR firmware. Lately, the phone has been unusable as it freezes up ~10-15 seconds after boot. I need to reset it. My question is whether I can flash the AT&T 11Z tot, or do I have to reflash the PR version?
[LG G Flex 2] hyelton:
Your not supposed to flash the PR version in the first place.. That's a different model for PR. You may not be able to go back. If you do it will be a risk of full brick type or thing.
[LG G Flex 2] febkosq8:
I have used the ATTh950_11Z.tot available from the link mentioned on the main post .

Its rooted ATT 5.1.1 .

also forgot to mention that about 2 months ago the device started to reboot randomly at various occasions mostly when it was very very hot .

I have no idea if it's anyway related to software other than hardware ?:confused:

also none of the shops nearby have the replacement parts as i am outside us .
[LG G Flex 2] hyelton:
Sounds like a hardware issue or battery. Best bet it to buy a battery online. If that doesn't fix it then it's definitely a hardware problem.
[LG G Flex 2] clickanu:
Thanks for the reply. I am actually not want to downgrade, just try to reflash your 5.1.1 on the same version that I did before. but this time, with thee same file I have got the error. Is there any kdz of H950 for 5.1.1?

thanks in advance
[LG G Flex 2] hyelton:
If your flashing the same file thats on your phone then theres no worries. What is the error? that would be helpful :p It can mean anything. And as stated the AT&T model is TOT method only.

This is the error, I always have while trying new flash with 5.1.1 by your method.

That error usually relates to a file error(bad download) or a computer problem. Did you redownload the file? Reboot the computer?

Using a USB 2.0 only port right as well?

Hi, my phone started boot looping the other day, which is frustrating because this is the first phone I've ever had that I didn't root or hack in some way... Lol anyway. I took it to sprint and the tech there said he couldn't do anything with it so I found and followed all of your instructions here and it successfully flashed zv8 tot, but when it went to reboot it never came back on and now it doesn't even respond to the charger cord.

This guide bricked my ls996 sprint flex 2 . It's either that zv8 wasn't the latest or some misguidance of the dll's . It's on qualcom now , my phone was working fine before this , i made a mistake of returning to stock . Please some mod look into this, thanks.

I've uploaded the log for further guidance. People with sprint ls996 don't make the same mistake i did, don't follow this guide at all.
[LG G Flex 2] hyelton:
This guide didn't brick your device. Also the DLLs are more of recognizing the device and wouldn't have anything to do with bricking. I'd suggest you read the OP about downgrading a Sprint device. You most likely had a newer software version which should of been checked. B

Remember anything you do here is at your own risk and no fault of others.
[LG G Flex 2] mafiadog:
I know that, i've uploaded the log file in previous post for your consideration . Yes i admit it is my own risk and fault so on second thought i'd suggest sprint owners to stay away as it does result in brick.

Edit : I further take my words back , it was my mistake after going through the logs. I downgraded from zvb which was the latest version indeed.
