LG G3 "No OS Installed" - G3 Q&A, Help & Troubleshooting

Hello I have not been here long but anytime I need help with something pertaining to a phone I come here.
So here it goes. I got an LG G3. I got root then I installed Bump'd as it was released. I then installed a custom rom and all seemed to be good. A few weeks later my phone got stuck on TWRP custom recovery. I managed to get that fixed by finding a thread on this web site. Now I was going to install candy rom from the Sprint LG G3 section but as I wiped Cache and all that other good stuff what ended up happening is that it may have wiped something it should not have . Because now the phone will now only boot to TWRP, and it keeps informing me that "No OS is installed."
Now here's the tricky part. It doesn't seem to want to go into download mode either.
So all I can do it TWRP.
So I have two questions
1. I heard that you could possibly put some sort of file on an SD card and flash it on TWRP to fix it. Is this true ? If so, can someone direct me to how to do so with instructions?
and
2. If #1 does not work... does that mean that my phone is screwed and there is nothing I can do with it at this point ? I have soft bricked phones but never something like this.
Help anyone as I would like to get this fixed ASAP if there is some way to fix it.
Please and thank you!

[Q] Whats causing this problem?

Sup, so in my last post I was told to read some info, get a better idea of what to do and how to move forward.. Problem being is, Where do I start? There is no actual help for the situation I am stuck in.
Im on a unlocked M8, no carrier version. I rooted the device and installed TWRP. This restored my Kit Kat 4.4.4 to 4.4.2. This is the google play edition, I believe.
Here is the Situation.
followed a youtube guide by "unlockr" which seemed to cover every aspect. after the root and with TWRP, phone bugged me to do a update to 4.4.4, I did, went back to TWRP, booted to system and got stuck in a loop.
I was recommended to delete the OTA file to stop this.. I did. Didnt stop the loop, bizarre...
Along this process, In fast boot menu my phone had a *tampered* label up top- further research this is nothing to worry about.
but without the OTA file, and just entering fastboot>twrp>system, this is where the boot loop still persists. S-On is back, no longer S-Off.
I've done my research etc and aware what needs to be done, but unsure on the safe methodology to reach this point. A friend who is helping me has better knowledge for SSung Galaxies and struggling to help me along.
He detailed I need to get back to 4.4.4(to stop this pissing 'you need to update your phone' pop up) - create a back up of this, then root and then from this point I can install custom roms ETC.
How do I install this, set up phone to a point Im happy, make the back up without the boot loop stopping me from doing so, then continue with experimentation etc...?
Like I said, Ive read plenty, but it doesn't help the situation I am in, so please, please don't just tell me to go educate my self, when there's no resources to help me with my problem. I still dont know which OTA is safe for me to use, or how to inject this without the bootloop ruining my life.. again.
P.S in work, Will reply when possible.

As far as i know there is no way your android version would downgrade by flashing a recovery. Most likely is you were and still are 4.4.2

Also pretty sure flashing a recovery can't turn S-ON and you have to be 100% stock for that anyway (I believe) which you are not. How did you get S-OFF in the first place??

There are a couple of things I'm not sure on, I think you have done the following so far
1. Unlocked using HTC dev
2. Rooted using the tool kit
3. Tried to install the OTA
4. Got a boot Loop
Is that correct?
Can you get into TWRP recovery?
Also you have a thread about this open already. Either delete that thread or this one.
As far as i know there is no way your android version would downgrade by flashing a recovery. Most likely is you were and still are 4.4.2 - Nope, Upon taking out the box on day 1, there was an update required and did it straight away.. then a smaller one. Guessing thats 4.4.3 and 4.4.4.
Golden rule - Never Never Never take an OTA when running a custom recovery - hahah, Ive established this now >.< I originally saw rooting as a "inject" sort of methodology.. before the os booted.. Thats not the case!
Also pretty sure flashing a recovery can't turn S-ON and you have to be 100% stock for that anyway (I believe) which you are not. How did you get S-OFF in the first place?? - I rooted following "TheUnlockr" video guide, It did say S-OFF, Bootloop and **** up with the OTA removed this I think. This was using the Hasoon2000 AIO tool.
Samsung are completely different. I know as I've rooted my GF's and it was painful - Good to know, I wont take too much advice from him, he did highlight a tool called Odin. Would that be any benefit to myself?
1. Unlocked using HTC dev
2. Rooted using the tool kit
3. Tried to install the OTA
4. Got a boot Loop
Basically.. yes.
Yes I can get into TWRP, but as I say, when I boot to system, this is where the loop starts.. phone starts up normally.. gives me 1min before restarting over and over.
I am sorry, Im aware that another topic is open. I did try to close it, dont have permissions on account. havent used forums in a few years and its all over the shop now hahaha.
Sorry for late reply.. hectic couple of days.

[Q] LG G3 not working at all after root

Hey guys I really need your help with something! I recently rooted my LG G3 using stump and downloaded an application that needed to restart my phone so I did and now when i try to turn my phone on all I see is the LG load screen but nothing will happen after that. The LED continues to flash at the load screen, but it wont go anywhere. Also, I have tried to wipe cache, factory reset, and apply updates in the recovery area but nothing seems to work. I have also tried doing a factory data reset but like everything else i can only make it to the load screen. This is the first device i have ever rooted so I am very new at this but I really need some help!
Sounds like the app did something malicious. What app?
I would like to make a suggestion for you and for other noobs planning to root and mod their devices.
Firstly every single person whom ever tweaked their device flashed custom ROMs, Kernels etc either has or will need some help at some point.
The most valuable point that I can stress is this, before you root, find out how to undo it and how to fix or troubleshoot different senarios.
If you see the LG animation then this means you have any number of ways to fix the issue(you're not doomed), check the tutorials, do some reading and search its all here, you managed to find out how to root etc so now do a little more to find out how to fix, good luck.
Can you enter download mode?

[4.4.2][CWM Recovery][E98020h]LG Optimus G Pro CWM Recovery Error/FreeGee Error!

Recently, I have been introduced to Android Rooting and I have successfully rooted my phone with Towelroot. My friend installed Cyanogenmod 11 on his Galaxy S3 the other day and I have been having many problems doing the process myself. I have ripped xdadevelopers to pieces trying to find a solution, but nothing has ever been simple enough, well really efficient enough to fix my problem.
I have ROM Manager installed on my device and the latest CWM Recovery and when I get to the "Recovery" mode it does not give me all the options a normal "Recovery" screen would give me. I can not backup my current stock rom because there is no option. In doing this I accidentally wiped my phone and had no way to recover, so I lost a lot of temporary things, very frustrating.
Basically what I need to know is how to get CWM Recovery to work on my device, etc. Also I forgot to mention before that FreeGee messes up too. It says something about "loki" or something. I am sick of trying several methods that fail in the end. If you can tell me how to get CWM Recovery to work on my phone. I do have an SD Card and my phone is rooted. Please help me! I apologize if all the information is not present, but if you need to know anything specific I would be more than happy to answer your question!

Have you tried installing the recovery from G.Pro Recovery first? Freegee will not work for me, giving me similar errors, until I first do that. See the to the Bountyman G3 v4.x thread under 'Optimus G Pro Android Development' for more info. Works for me every time (though I choose TWRP; friggin' *hate* CWM).

No OS on galaxy n4 sprint. No back up or restore point

No OS installed. I have twrp installed. So literally when i turn it on it goes directly into recovery menu. Apparently I have no back up or restore point. This is a Sprint galaxy note 4. Does anyone have any suggestions. I have been looking for a factory reset firmware somewhere online cant find one. Funny thing is my wife has the same exact phone. I thought making a back up and restore point for her phone would work on mine, but it didnt lol. Please I would be very grateful for help.
Hello, you could get the official software and use odin to get it back all the way to stock, or you can also just flash a custom rom since you already have twrp. To install a custom rom, all you need to do is download the rom and place it on a micro sd card, boot into twrp, and flash the rom from the micro sd.
Thank you for your reply how ever my trouble is finding an OS that works for my note 4 sprint device. I have downloaded dozens and dozens of different roms and so called " factory firmware" but seem to have no lucks. i have the recovery software installed twrp. when i go into there and try to load rom i still get error that says no os installed..
Thanks for the input i will close this thread now. my problem was not being patient at the bootload screen. I automatically assumed that something was wrong because it was stuck at the sprint spark yellow screen how ever little did i know a little bit of patients would have saved me numerous amounts of hours of research. Lost sleep, called off of work, and canceled weekend plans due to a little lack of patience. Well you live and you learn i really appreciate you taking time out to reply.

Soft Bricked LG G3, trying to get LineageOS on it. (Success!)

I was needing a new phone and saw a Linus Tech Tips video where he took an LG G3 and put LineageOS on it. So I thought I'd try it out for myself following his guidelines at https://linustechtips.com/main/topic/1058206-lg-g3-lineageos-tutorial/
I bought an LG G3 D851 (T-Mobile version) off EBay for this. It's my first Android phone (yes, experimenting on my first Android Phone), I've always used Windows phones. This is what I've done to the LG G3 so far:
I reverted back to KitKat. Everything seemed to have gone just fine.
Then I downloaded the the Full Purple Drake Root and ran that after I figured out that .gz files are a compressed file and that can be decompressed. Everything seemed to have worked fine.
Then I downloaded the TWRP app on the phone and tried to backup the recovery via the TWRP app, which I'm not sure if it worked correctly. But anyhow.
Now that I'm writing this I see I missed this step:
number seven: Select the TWRP file we copied over earlier in the app, flash it to recovery, and then reboot to recovery
Click to expand...
Click to collapse
I guess I just didn't understand what was meant by flashing it over and has just copied it to the phone's memory which I later wiped.
Well then I went into TWRP recovery and tried to do a recovery backup, which it seemed to do just fine. I rebooted and tried copying it over to the computer, which seems to not have worked. I just have an empty folder on my computer as we speak.
Then back in the TWRP recovery, I selected Wipe>Advanced Wipe, and select Dalvik, Cache, Data, Internal Storage, and System – then swipe to wipe.
Then I downloaded the latest version and nightly of LineageOS zip file and the Opengapps zip file but then had a hard time figuring how to get them to the phone.
I figured out that I could stick them on an SD card and slip it into the LG G3 that I'm working on and could see the files from the TWRP recovery menu.
So I tried to install the LIneageOS zip file several times and it didn't work. I'm guessing it's because I forgot to flash a certain file to TWRP recovery and am not sure how to do that, especially now with the phone only booting into recovery mode with the TWRP menu since it's wiped clean and will just display the LG logo and turn the LED different colors if I try to normal boot the phone.
Well I still want to try to fix the phone and go for LineageOS. I spent nearly all night working on it so I may give it a rest for a few days. But any help or pointers would be greatly appreciated.
Now that I think about it, I didn't do what I mentioned ok #4 above about flashing the TWRP recovery because TWRP recovery was installed with the full Purple Drake root. However, the Linus Tech Tips instructions point to them rooting the phone with the lite version of Purple Drake (root only) and then flashing the newest version of TWRP recovery. So I wonder if my problem has to do with my having the latest version of TWRP recovery on my phone.
Ok. So I think I'm making progress, although that's just a feeling I have since I'm not suite what I'm really doing.
Anyhow the error code was something like "Unknown Error, Error Executing Updater Binary in Zip, Zip is for LG G3 D851, this phone is...(blank)". So I found an article in DroidThunder.com talking about this very problem. It suggested unzipping the rom on my computer and looking for the updater-script file and erasing some lines that apparently only have to do with verification. Then re-zip and retry.
Now I'm getting a "No MD5 file" message followed by an "Error flashing zip" message.
Edit: After reading this I take it I have an older version of TWRP, that is, v2.7.1.0, whereas the newet versio (for this phone?) is apparently 3.3.1-0. That seems to have an effect on this. I wonder if it's possibly to flash a newer version of TWRP onto this bricked phone. Anyhow, I'll have to look into that later. It's time to call it a day.
So recently I've been focusing on these two threads:
[GUIDE] LG G3 D851 Unbrick Qualcomm 9008 Fully Working... Unbrickable D851! by Omar-Avelar
And:
[GUIDE][FIX][DISCUSSION] LG G3 Hard Brick Recovery by l33tlinuxh4x0r
But I can't get either of them to work. I guess the only other thing would be to try to find a ROM, preferably the original KitKat that came with the phone, and hope and pray that I can get TWRP recovery v2.7 to install it.
I have the original as a tot file. But as far as I understand, I need a zip file that's set up for TWRP recovery.
Anyhow, trying to get this phone running hasn't been easy and has made other problems. Now every time I turn on my Surface 3 I have to go through BitLocker authentication. Hopefully turning bcd Test Signing off will stop that. But I'm getting to the point that I'm feeling like giving up.
Well that's it. Last night I found a zip file for the original Marshmallow ROM for my G3. I got it onto the SD card, went into TWRP recovery, saw it install, restarted and...
Now it's hard bricked. I cannot even get into TWRP recovery. The screen won't show a thing. I tried several times to get it into any mode possible, normal boot, TWRP recovery boot, download mode, and that jumping the pins trick, and I can't get it to where I can do something with the phone.
So I'm giving up on all this rooting, custom recoveries and custom ROM stuff. It all seems like a good idea, and I'd love to be a part of it all. But I take it this isn't for me. So I give up.
Thanks to all who have worked on this and have made the helpful forums about these phones! Maybe if I were more competent I would have figured it out.
Well, I said I was giving up. But maybe not. I did give up trying to recover the phone from being bricked and sent it out to a JTAG shop. For about $40 the phone is supposedly fixed and on it's way back.
But when it's back, do I just leave it alone this time, or should I try to get Lineage OS back on it again? Well, this is something that I haven't made my mind up yet. I see where I had made several mistakes when I first tried to get LineageOS on it. Maybe I know enough now that it won't happen again. But at the same time there's no guarantee that I won't me it up again, and have to pay some $40 again to have it unbricked.
SUCCESS!!!
So I got my phone back with stock Marshmallow working. Then I carefully went through every step on the Linus Tech Tips site, including installing the latest version of TWRP, and the next thing I know I'm running LineageOS 16 on my phone!
This is great! It's my first Android Phone and I've got it setup just about perfect! The only thing I kind of miss is Wi-Fi calling. But that didn't work so well on the Alcatel Window's phones I had anyway. But I got all the apps and most of the music I need installed and am ready to go! I also have two batteries, and the original isn't too bad, so I might carry that around as a backup until I'm sure how much battery I'll be using.
I'll be coming back and thanking all the ones who's posts and work have helped me individually. But if you read this and are one of those who have worked on TWRP, LineageOS and anything else that has helped me, Thank You!
