Lg g2 no os at all - G2 Q&A, Help & Troubleshooting

Hi!
First I tell you how I recently messed up my LG G2 D802.
I hadn't had a custom rom for ages and now I wanted to have one (This wasn't the first time. I've done this a lot earlier). I had always had root access, but not custom recovery. So the first thing was to install one and I chose to download Rom Manager from Google Play, and then install ClockWorkMod. So, when I was installing the custom recovery I came up with a problem: something went wrong during the installation (I have no idea why). When I booted the device, white letters and numbers appeared on the top left of the screen, saying something like: "boot certification error" and numbers like "[780] [800]" and so on. The screen went black and the phone didn't load the OS. So I was shocked of course because I had never had such a problem.
So, desperate for trying everything to find the solution, I tried tens of ways to try to fix the problem. Finally I read about thing called SRKTool. So I used it and ended up having TWRP on my device, and no OS at all. I tried to flash CM12 and CM12.1 (downloaded from the official site) but nothing works out. TWRP says that flashing the ROM is succesful but when rebooting the system it doesn't load the OS but it comes back to TWRP Recovery mode - WHATEVER I DO. I can't enter the Download -mode at all. I tried hard reseting (Power + Vol - keys), but once again it boots to the TWRP. I can't understand why the TWRP fails to flash the ROM even though it's saying the process was successful. Or maybe this problem is much more internal - and permanent.
After tens of XDA developers' threads I'm writing this here because I'm in need of help. I want to bring my G2 to back in life. I'm out of ideas. Can you help me? I tried to flash the stock firmware but guess what happened? The installation failed, and the device booted back to TWRP. So all I'm able to do is to use the TWRP Recovery. I appreciate your help. Thank you.
(Ps. I'm sorry if I break the rules by writing a new thread. My problem just seems to be so unique that I couldn't find help anywhere.)

If you have access to twrp than you can do what ever is needed
what twrp version douy you have?
enabel MTP, so you can copy from PC

The solution is easy. Download the stock rom for your model and install it with otg cable. The reason cm12 is not booted is because you need jb bootloader or caf bootstacks.

The current version is 2.8.7.3. Should I try other versions?

Did you solve the issue? Or is it still not allowing you to get into your F/W?

Hi!
I tried to install TWRP version 2.6.6.3, but it fails to flash it so I'm stuck with the version 2.8.7.3. All I'm able to enter is just the recovery mode. I can't enter the download mode so I can't flash the stock firmware.
Currently I'm out of ideas. I can't flash any OS, the TWRP fails everytime and creates errors.

Try flash bumped kernel like lp dorimanx then flash bumped bootstak then lp rom like cloudy or stock. Or google this: lg g2 unbrickable now xda ...that work for me

My phone is back to indian version but its slow, not too much but its slow; camera, gallery and other apps take some time to open. I can't make or rcv phone calls. Now what i did is download the update form System update.
Now i got kitkat rom.zip but twrp failed to install it.

Hello my friend, please help me.
I am trying to flash stock inidan rom 4.2 but.. I installed all CWM for E7 found on the internet and I am getting black screen. I managed to Install TWRP but TWRP cannot flash the rom that I need to flash. I flashed a chinese 4.2 but is piece of garbage..
gngc-download-tool said that the com port is closed.
I have windows 64 is this the problem causing gngc not working?
No its not, it is working on 64bit windows very well.
In TWRP factory reset and format system and data, than install
Chinese 4.2 ROM. After that boot it and try it again.
It should work!

For me...problem!
there´s a cwm recovery that flashes over the kernel...
i flashed it and than i was unable to go to recovery, every time i tried the phone power off
Solution: Flash the stock boot.img
Use the file according to the Android version...
Help
I just rooted my gionee elife e7. Flashed the chinese recovery which seemed to be the only one which would be compatible. But, while changing a few setting using pimp my rom, the software just stopped working. Errors keep showing up on the screen - "system.ui is not working", "android app is not working", I cannot even go the settings because "settings is not working". Third party apps still seem to work, so, whatsap and stuff continue to function. Doing a factory reset or flashing firmware again seem to be the only viable option.
But, when I try to load up the bootloader using the power and volume keys, it gets stuck on the screen showing the gionee logo and it reads 'fastboot mode' in the bottom left hand side corner. So,
a. can you offer any advice which may be useful ?
b. can you share the link from where you got a TWRP recovery which will work on the Elife ?
c. do you have any idea what exactly went wrong here ?
Any help you can provide will be appreciated because, it's my mausi's phone and I will have a very tough time explaining what really went down here.
Regards,

[RECOVERY] [TWRP 3.0.0-0] for Vodafone Smart Prime 6

Hello guys.
I have successfully ported TWRP 3.0.0-0 for our Smart Prime 6.
It's 100% working !!
There are NO BUGS !! :good:

________________________________________
How to install​​
Via app:
1) Download TWRP 3.0.0-0 from the link above and place it on internal storage of your phone.
2) Download Flashify app from Google Play Store.
3) Open Flashify app.
4) Grant root permissions.
5) Click "Recovery image" and then click "Choose a file"
6) Navigate to the folder where you placed TWRP 3.0.0-0 and choose the .IMG file.
7) Press "Yup!" button and wait.
8) After a while the phone will require reboot. So click "reboot" button.
9) Phone will reboot and automatically boot into TWRP, so you can press reboot to system.
10) Enjoy!
Special thanks to Oneb1t for modded .fstab file! :highfive:
edit: you can use Flashfire app too instead of Flashify, but it's not recommended, because the latest version of the Flashfire app is not flashing properly.
Brilliant! Thank you so much! Do you know any custom ROM what is better than the factory ROM?
There is no custom ROM for this phone yet.
But I'm trying to make LITE ROM.

Do you think it's easier/possible to adapt a ROM from a similar device like say, the Alcatel
Pop 2 (5) Premium ? I don't know if there's any ROM for that phone tho, but since it's branded as Alcatel you might get more support from the community here than by using Vodafone's name.
Hello, Demonlord6.
I have tried to make a stock flashable ROM via dumping the system folder and the boot.img file, but without success.
It does not boot properly.. when I tried to flash it without dalvik/system wipe everything was as before.
When I tried to wipe /system and dalvik first and then flash the ROM, it causes bootloop.
So now I'm trying to fix this issue..
I don't know where the problem is.
So when this issue will be solved I will try to build a ROM from Alcatel phones with same specs.

Hey, Andreno306
I don't know much about Rom's in that level of expertise I'm afraid :/ but I did some digging and came across this simple tutorial on XDA:
http://forum.xda-developers.com/showthread.php?t=2387941
I imagine it does not work for every single device out there, at least not with modifying stuff after, but it might be a good starting point I think, in fact I would try to actually make one myself had I a working PC currently at home. But even if I did I had no way of testing it because this is currently my daily driver phone.
Just wanted to say that I'm also very interested in getting a slim ROM for this device. I can't offer any expertise I'm afraid! Just wanted to show that there are people interested in your project.

But I recommend to restore it with the flashify app, because that's how the backup was made.
If, for some reason, you don't/can't restore it, then you can always try Sugar on the PC which basically restores everything to factory settings (recovery, kernel, etc, it all gets reset)

Sorry there about the bootloop but glad u could restore it from TWRP, maybe it was because we have different ROM versions ?

Sorry for the stupid question but... does it works on Smart Prime 7 too?
Has anyone installed that linked ROM? It seems to be what we are looking for... a slim debloated rom.
I presume we need to be rooted, install this TWRP, then flash that ROM?
It mentions unlocking the bootloader, I dont think I've seen any info anywhere about unlocking the bootloader.
Can anyone give a quick lowdown on all the steps required to install that ROM please?
Hi everyone, I discovered that Elephone Trunk and Smart Prime 6 have (almost) identical specs: https://www.devicespecifications.com...ison/c584481c6
So it would be great to "port" (or build ?) the official Nougat-OmniROM for Trunk to VF-895N: http://dl.omnirom.org/trunk/
Last but not least, here's official Vodafone Smart Prime 6 sources: Vodafone_Smart_prime_6_20150413.tar.xz
TWRP for vodafone smart max 4 990N (coolpad 8890u).
I tried this recovery image for vodafone smart max 4 990N (coolpad 8890u).
The phone is in a bootloop state. I think i have usb debugging enabled already.
So, in fastboot mode i can see the device in my pc in adb fastboot cmd.
Im trying to ''fastboot boot recovery.img" but it stops in ''booting..''.
Dont know whats the problem but for sure i can not find a specific twrp image for this device.
If i enter fastboot oem device-info it says ''(bootloader) Device unlocked: true''.
Any ideas ?
hi i was wondering if you could share how you did this or if you can make one for the Vodafone smart n9 (VFD720) it would help a lot of people out looking for this
Needed to root a Vodafone Smart Prime 6 (VF 895N) (got it from a friend because it became unresponsive from all the updated google play stuff ) to get linux-deploy running. Just wanted to leave a big thank you here for Adreno306 for his TRWP 3.0.0-0. it did the job very well!
Only the procedure to get it installed differed quite a bit for me, since Flashify is no longer available.
I wanted to preserve boot and just flash trwp to recover, what worked quite well.
The first thing I did was to boot the phone manually in recovery mode (Power+Vol up) and reset it to factory settings from there. It takes a little while. Then follow the setup, go to phone settings, enable developer mode and set usb debugging. If "unlock oem" is not available there, reboot into recovery again, set unlock there and reboot into bootloader.
The prerequisites are adb and fastboot, both must work. Means adb devices and fastboot devices must show the phone. What can make problems under win10 as it sometimes does not detect the phone in bootloader mode. An actual google usb driver is needed, as provided by google.
For me adb worked well, but when rebooted into bootloader with adb reboot bootloader, fastboot didnt detect the phone. With the phone still connected, the windows device manager showed an unknown device with and exclamation mark (!). Right click, install driver, select driver manually, select driver from device list, mark all devices (first entry) and click "disk", then point to the usb driver director and select "ADB fastboot driver". ( A more comprehensive description is available here )
Once adb and fastboot detect the device, it is time to prepare it. Boot to system (normal operation) first. Make sure that the TRWP 3.0.0-0.img is renamed to trwp.img and then
adb reboot bootloader
fastboot devices
fastboot oem unlock
fastboot boot trwp.img
Now the phone should show the trwp menu, set it up to root the phone and install SuperSU. Reboot into bootloader and
fastboot flash recovery trwp.img
fastboot reboot
Verify with adb reboot recovery, you should see trwp now. Reboot to system.
Now finally go into the app selector, start SuperSU, and root the phone. SuperSu uses trwp recovery mode to install its image and root is done.
Again, big thanks for providing the TRWP image!

Rooted, Custom Rom a huge fail

Hello dear Community!
It is depressing that my first appearance here is to ask for help, but I am going crazy.
So, I tried to Root my phone via Odin + CF Autoroot klte and it seemed to have been a success.
The root checker also said, that my device was rooted so I went on and installed TWRP to be able to install Lineage OS.
After getting Lineage to work I got a few error messages suddenly popping up, telling me that either "Music had stopped" or other android operation were closed because they didn't work properly.
I tried to install Gapps, it seemed to have worked but I was only able to open and enter the store once, afterwards the store never managed to load and then the app closed itself after starting it.
So I checked again with Root Checker, but this time it gave me an error message, too. It said, that my device was not rooted properly.
I guess this is were I made it worse by deciding to just root the phone again. Obviously, it didn't work either.
Afterwards I thought that maybe installing The Original Android OS and then unrooting the phone would be the best solution to be able to start anew.
First I tried to flah Lineage again and that made it impossible for me to boot the phone. The farthest I got was the setup page, were it tells you Hello and were you can choose a Language, but clicking the arrow key didn't do anything at all.
The recovery mode was also not the TWRP one anymore, but the original Android one and that was a huge problem for me.
Then I tried to flash the 6.1 OS for the S5 (I made sure it was the correct version), but now it is stuck at the "Samsung" screen while it boots.
It never boots though.
I don't know what to do anymore.
Please, I beg you, could anyone help me out?
Don't flash the latest Lineage OS ROM
Hello AsylumAlice u shouldn't have flashed the latest Lineage OS ROM because now u will need a new motherboard for your S5 since the ROM corrupts the MMC chip now u will need to get a new MMC chip or a new Motherboard sorry that your s5 is now hard bricked but when u get it fixed flash the DreamUX S8 Rom it works flawless on my S5 SM-G900i

What are the grounds for your claims?
You needn't root via CF-autoroot if your end goal was to flash lineage. CF autoroot was intended to root stock roms with ease and less effort.
Flash The LATEST, official TWRP via odin then do a FULL WIPE. Wipe system, data, cache and dalvik cache.
From here on, you have two options:
1.) Sideload the LineageOS rom via ADB
2.) Transfer it to the phone's storage via MTP and flash it from TWRP.
As for how to accomplish this, the forum search bar and Google has your back. You need only choose one procedure.
If you need the Play Store, flash gapps AFTER flashing LINEAGE AND BEFORE REBOOTING.
Since you were under the idea that utilizing CF-autoroot was a necessity, I suggest that you re-read this post thoroughly before actually putting it into practice.

Thank you so much for your fast reply!
-> I flashed the newest Version for klte via Odin, but I can't get into the boot mode.
I only am able to enter the download mode. What can I do now?
Flash TWRP via odin again, untick the Auto-Reset option of Odin first. Then try booting to recovery via long holding the power, home and volume up button simultaneously without releasing any of the buttons until you successfully see the TWRP splash screen.
If that still doesn't work, reboot to recovery via adb from download mode. You need the adb and the usb drivers for your device.
If that still doesn't work, you might have flashed an incompatible version of TWRP.

Thank you so much, it worked perfectly!
I can now start my phone and use it normally.
But the Root Checker still says:
"Sorry! Root access is not properly installed on this device.
Device: SM-G900M
Android version: 7.1.2"
What should I do from now on?
Thank you so much for your help (agaiN).
And as for why I used the auto-root, well I just followed a guide that I found, it only had positive reviews so I assumed it was a correct tutorial.

I thought about doing that, but wasn't sure how exactly to proceed and what Version to install.
I downloaded SuperSU v.2.82 and put it on my internal storage.
Just install over TWRP the same way that I Installed Lineage and Gapps I suppose?
I guess if it doesn't work out, I just follow the steps from above again and retry?
Thank you so much. I feel like in idiot in this situation.

I thought about doing that, but wasn't sure how exactly to proceed and what Version to install.
I downloaded SuperSU v.2.82 and put it on my internal storage.
Just install over TWRP the same way that I Installed Lineage and Gapps I suppose?
I guess if it doesn't work out, I just follow the steps from above again and retry?

[Bootloop] N9005 not booting after frame (display) replacement

Hi,
as the title says, my phone is not booting anymore, after I transplanted the motherboard from a frame with a broken screen into a new frame (from china).
Abbreviations used:
RR => Resurrection Remix 5.8.5
CWM => ClockWorkMod Recovery 6.0.4.6-kitkat
TWRP => TeamWinRecoveryProject 3.2.1-1
I was using RR from the Rock Stable Setup on it before and it worked beautifully.
What happened:
I performed the mainboard-transplantation according to the iFixit guide
I held the power button to boot the phone:
It vibrated
It showed this screen for a couple of seconds
It vibrated
Back to step 1
And that until I removed power.
Then I tried to boot into recovery mode by holding the key combination on boot:
Same as above, but with this bootscreen
Then I tried to boot into download mode by holding the key combination on boot:
The warning to confirm download mode poped up and I got to see this screen.
I connected it to my PC and opened odin 3.09 and it recognized the device.
I tried to get adb and fastboot to see the device, but nothing worked. (In the old frame and before I broke the screen, it would be recognized at this stage)
I flashed TWRP with odin, odin showed the green "PASS!", but booting to recovery still failed.
I proceeded to flash a stock ROM, which had worked when I had issues with RR.
It worked, I went through the Android 5 setup process, enabled debug and connected adb.
adb saw the phone.
I rebooted to recovery and stock recovery booted correctly.
Sideloading anything with adb failed due to signature verification.
I then went back to download mode and flashed CWM successfully.
It now boots into recovery, but whenever I try to flash anything with CWM, it fails showing this screen
Or something similar (the photo comes from flashing RR 5.8.5)
I have both linux and windows properly setup and used both with adb, fastboot and odin (only windows)/heimdal (only linux).
I checked drivers and usb cables.
I opened the phone back up and checked all connections.
But I can't get any version of RR, CyanogenMod or LineageOS on there.
I've searched the internet, but people that have these kinds of problems after replacing parts of their phones, seem to only have driver issues or skipped steps in the manuals of custom ROM installations.
If you have any idea on what I could try or what I'm doing wrong or not doing, please leave an answer.
I'll keep this post updated below here:
(no updates, yet)
Thanks so much in advance

Your picture shows stock recovery not CWM .
Try flashing TWRP recovery through Odin .
I did flash TWRP and afterwards there was no recovery anymore.
When I flash CWM, I get the recovery shown in the photo.
The stock recovery has a black background and no touch controls for me.
What you saw must have been CWM.
Update: I can flash twrp-2.8.7.0-hlte-4.4.img.tar and it works. It's the only image that works, but I still can't boot into or flash any custom OS.
The only working OS I have at the moment is a stock android 5.0, which is not all that useful...
If anyone has an idea, why I can't or how I can find out what is causing it, please say so.

What do you mean by ANY ??
Well, exactly that.
Regardless of what zip I flash, I end up with a bootloop.
If I flash a recovery zip, the recovery bootloops, but the OS still boots.
If I flash a custom ROM, I can still boot into recovery fine, but booting normally results in a bootloop.
The only way to get software onto my phone has been via odin and only an old CWM, Philz Touch, TWRP (Version 2.8.7.0 and below) and STOCK Android (Versions 4.3, 4.4.2, 5).
Anything else I have tried so far did not result in an error, but I couldn't boot into it either.
If you have ideas for software I can try flashing, please tell. I really have no idea how to get the damn thing to work again...
What happens when you flash correct stock rom via Odin ??
I mean that I can boot into it after flashing it via Odin.
But its terribly slow and bloated compared to ROMs like ResurectionRemix, so I don't want to use it.

In that case phone is OK .
Usual is that user is failing to follow instructions .
Not sure what you mean by fastboot on a N9005 .sounds like not a N9005 .
Personally with TWRP 2.8.70 i would be flashing something like .
https://forum.xda-developers.com/galaxy-note-3/development/rom-magma-nx-rom-t3508672
as its correct TWRP .
I am able to follow instructions.
Thank you very much.
I followed exactly the same procedure that has worked many times when switching between custom ROMs.
Also, the phone has a perfectly working version of Ressurection Remix installed at the time my frame broke and it did get stuck in the same bootloop after replacing the frame, even thogh the software was exactly the same.
I am looking for help analyzing the boot process and some way of capturing the kernel log when booting to determine where the error occures that traps the phone in a bootloop.

Dear Mate..
Have you solved your problem? I have same problem after transplating N900 frame.
Sorry, I gave up, since I dearly needed a working phone and bought a OnePlus 3 cheaply from ebay second hand. It's been working like a charm and I threw the note into my museum after I softbricked it for the n-th time and couldn't get it out of a bootloop that didn't leave me time to go into Fastboot.
Sorry friend, but I can't help with this.
after reading a lot of similar threads, seems like the hardware is the cause of us not able to update to higher versions of twrp(& custom roms)

Lenovo tab 4 10 Plus TB-X704V loop reboots

After failing with installing different versions of TWRP om my tablet (There is no working version on TWRP for my model- system revert itself to the Stock recovery mode), at some point I noticed, that I can power on tablet and get to Welcome screen and start tablet configuration, but right after 20th seconds system freezes for few seconds and reboots over and over. If I just power on system and let it stay without touching screen it will reboots after 20 second.
If I go to the Recovery mode, there is not reboots. I did system hard reset in Recovery mode no help.
I thought it is problem with ROM, and flashed Stock Rom with Lenovo MOTO Smart Assistant. Same issue with reboots, then I tried some other ROM’s regions with same issue. Before I got this issue, other ROM’s used to work just fine.
QUALCOMM flash utility did not help as well.
I am just interesting is this issue with System board or it is software issue and I can fix this.
I have the same issue. I have been able to root through a patched boot image, but cannot get recovery to flash no matter what. It says all went successfully, but then always reboots. I have the 2GB version.
I just want to install an updated ROM since lenovo abandoned our devices.

I've just spent days trying to get my TB-X704V to flash. I finally found out how. The issue I ran into is the recovery mode never worked. I found one that did. Big caveat here. Once I flashed the recovery image, I could no longer boot the stock rom.
I found the recovery image looking for X704A, and ended up with the files at https://drive.google.com/file/d/1QyUGBPi-KZrhSVFLOCs3lHUZ59fpe9KL/view (not my files). This is Chinese/English version. You can change language in the menu.
Follow the directions on flashing it at the quick boot menu and unplug and go into recovery mode.
Download the latest lineage OS: https://androidfilehost.com/?fid=6006931924117916469
Install the OS. The initial boot will take a few minutes, but it will boot.
Most of what I found was in the thread https://forum.xda-developers.com/thinkpad-tablet/general/twrp-root-tab-4-plus-tb-x704l-f-tb-t3664407
Thanks @yener90 for your work!

Thank you so much, I was able to boot straight into TWRP using that Chinese/English image. I spent days last week unsuccessfully trying to boot my TB-X704V into the twrp-3.2.3-0-tb_x704l.img recovery image, but it never took no matter what I tried.
