LG G2 Wont power on (bricked?) - G2 Q&A, Help & Troubleshooting

I have the D803 and I was trying to get KK before the OTA as Canada we never get an OTA.
I rooted the LG, I installed the custom Rom, I installed an updated GAPPS and it wasnt working. I then went and installed another GAPPS overtop and I got stuck in boot loop. After I tried recovery from ADB I tried to restore from TRWP and it didnt take. After I rebooted nothing turned on, no LED, I tried ALL button combinations and nothing comes on at all. I am wondering if the phone died and now will not charge...I started with 60% but the last time i saw it it was down to 15% just thinking maybe it died completely and without any software to boot it wont charge...I have had it on charge for 8 hrs since and still nothing...ADB does not read it.
Please help!

Usualy is good to have at least 50% battery. Did you tried to charge it trough the wall charger ? Can you enter in download mode ? From fully shutted down , hold vlume up while plugging it to the computer. It should start by displaying Download mode logo. If you get to this point then the device is not bricked, and from here you should be able to reinstall the original 4.2.2(in my case is D80210A_00.kdz, because i have the 802 variant ).

Thanks for your reply,
I did have at least 50% and I believe I blew through the 50% during the process. I tried through wall charger for 8 hours yes Still nothing. I tried entering download mode (I tried all button combinations while plugged into the computer, plugged into the wall, not plugged in). I would love to be able to reinstall the original 4.2.2 This whole process has discouraged me from furthering my Custom rom use lol.

We're you trying to install a lg based kit Kat Rom or an aosp based Rom. You say you wanted to get it before the ota in Canada so it makes it seem as though you were wanting to flash an lg Rom but you say you flashed gapps. Gapps are only used on aosp based custom roms

"This whole process has discouraged me from furthering my Custom rom use lol." Not at all. Just a few days ago I "soft bricked" my phone. I had D80210a and i forgot to update it to D80210e, and went streight to root it and add recovery twrp. Everything was oky doky till i started updating the 10e the OTA way. It just stoped. I had no download mode anymore. But I was lucky enough to still have the twrp recovery . So I used the terminal command inside the twrp . I unbricked it using this command : dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
Note that if for some reason if I didn't had any recovery mode my other option was adb . Of course this thrilling adventure didn't stop me to customise my phone.

Sorry to sound dumb here, I am pretty much a rookie at this stuff I just follow directions well lol.
Where did you use that command?

I am guessing this was done through Ubuntu Which i do not have. What is the best way to run ubuntu on Windows? I have done some searching and would you think the virtual box (virtual machine) would be best?
Thank you again!

[Q] Cant Seem to Root EL30. Need help!

Ill start this saying, yes, im a noob. I rarely post or visit unless i have problems.
But i do have experience rooting this specific phone before. But this time around its giving me a LOT of problems...
Ill start with:
Samsung Epic 4g (D700.0.5)
FM 2.3.6 (GB)
BB EL30
K 2.6.35.7
Now i will attempt to explain all the problems as well as what i have done to try to fix them and i will give as many links to the pages that i used for guidance as i can.
As i said, i have experience rooting this specific phone in the past. I ran a stock rooted ROM and everything was fine other then some glitches that i just learned to live with. But about 3 months ago i got a few more problems that have been driving me crazy so i desired to reroot.
When i power down the device, it will not turn back on just by pressing/holding the power button. Removing the battery, reinserting it, and holding the power also dose not work. I finally figured out that i have to remove the battery, replace the battery, then quickly (before the on-screen battery disappears) insert a charging cable thats connected to a power source. Then when the battery turns green (even with minimal power or full power) i can then power it on, but only when the on screen battery shows green. If i wait too long and it disappears it will not work and i have to start over from the beginning. (Removing Battery...) That was the 1st problem.
Soon after this happened (maybe 1-2 weeks) my phone started doing random shutdowns and not powering back on (i assume because it didnt have a power source connected). This would happen at anytime of the day or night, even when it was connected to a charger and actively charging. Yesterday i finally had the last of it and started researching this problem. I found that apparently some/all of the epics have this problem in time. From what i read the micro(or mini im not sure) USB port dosnt fit 100% snugly. So it causes heat. This heat causes corrosion and eventually leads to this problem. (I have never got this phone wet in the 1.5 years i have had it, i take very good care of my electronics.) Around the time this started my phone also would drain its self in about 2-3 hours, this was due to it constantly thinking i was plugging and unplugging it from a computer and requesting that i choose from the 3 options of mass storage.... Eventually the whole screen turning black with the android and the 3 buttons went away but the pop up on the notification bar continued, and as already said, it will drain the battery quickly.
NOW on to the rooting problems.
I dont remember what rom i was running originally, but following a few videos from QBKing77.
I odin'd back to EC05. This went fine no problems. (Useing odin 1.85)
I then tried to use the e4gtauto.zip file and running the "RUNFIRST.bat"
Used option A (install Root not EL13/newer)
Everything went though like it was suppose to. No errors or problems. Phone rebooted into recovery rather then to the lock screen.
Not remembering how to use recovery, i did some research, apparently the camera button is SUPPOSED to be the select button, but this did not work for me at all. After several manual reboots (pulling battery) this was the only thing i could get to (not even download mode to try to flash back to EC05 again). I did some research and found a post that said the "home" button on the front of the screen was his selector for some strange reason. This worked for me. I selected "reboot now" or something like that (the 1st option) and it rebooted into what i was thinking was a rooted rom, checked and there was no SU, or BusyBox (as said would happen in the e4gtauto).
I downloaded an su.zip and figured i would flash it with CWM (last time i installed CWM it was "purple" or 3.1.0.1)
Well it seems that my CWM is gone... i did the ever famous "3 finger salute" of Vol Down + Camera + Power and nothing except that i had to select "reboot phone" again from what i believe is stock recovery. Which booted me back into EC05.
By this time it was late at nite (2am or so) so i went to bed, over night apparently it updated and is now EL30. Thinking this was a good thing (and deff proving im not rooted) so today i tried rooting it as EL30.
Still do not have CWM seemingly.
Also would like to note, inorder for me to get to download mode, i have to take out my SD card, take out my battery, plug in the phone, and hold 1+power when the green power indicator comes on as stated above. This is the only way i can get into DownloadMode (if that helps at all)
If i could get any information on how to root from EL30 i would appreciate it greatly!!!
I will answer any questions as fast as possible, and i will provide as much information as you request when as soon as possible.
Thank you all in advance.
LATE:
Im not able to post links... so i cant give all the steps ive followed so far, I have attempted to take out all infomration already stated related to a link or video... Sorry.
I can do this for you remotely via teamviewer 7 google it and install it pm me the id and password and ill do it all for you
Oh and you used the epic touch one click root... not ours.. and el30 doesn't work on one click root.

As i was writing the above i thought of something. What if i do the same thing i have to do in order to get into download mode to boot into CWM.
No, this dosnt work, it brings me back into the what i believe is stock recovery. I decided to mess with the "install from sdcard" option. I tried the various .zips i have on there and they all fail a signature check.

You have the wrong recovery installed... you used the epic touch one click root... ... just go get teamviewer and ill fix it for you.
oh but now your on stock recovery because samsung has a script in the kernel to restore the stock recovery upon boot.
The rooting has been fixed.
I didnt install a CWM file apparently
and i also did a lot of bad things

[Q] After 4 1/2 yrs on XDA I am finally stuck! Bricked No download mode, No OS.

Hello my fellow XDA Members. I am stuck in a tight spot and after reading and re-reading some things the situation doesn't look very promising. I hope this is the moment that Karma shows up and I can get some help on this. Here it goes.
Specs - LG G2 D801 Variant > TWRP V2.8.3.1 > NO OS Currently
I was running Cloudy G3 Rom smoothly and got bored and decided to flash that new rom that is a 5.0 Rom all variants. Did the usual back ups and flashed it. Something happened when I flashed the rom. It went through the Aroma installer and then said "successful" but stuck in a bootloop. I tried it again and nothing happened. Then I tried to wipe everything again and started getting an E: Cannot mount (data or system I forget which as that error went away after I completely formatted data, wiped everything and reflashed Cloudy Stock. )
> Cloudy stock bootlooped and nothing is happening in TWRP. I Am using the USB OTG method of getting files on the phone and getting it charged but anytime I try to do anything (flash a rom, an older version of TWRP) it just immediately restarts TWRP and thats that. I have No OS at all.
> I tried to use one of the methods to get into download mode and flash a stock KDZ but the phone acts like it is going into DL mode (shows the little blue transition screen) but never gets into the ACTUAL download mode where the PC or flash tool can recognize it.
So in a nutshell > No OS > I can get into TWRP but it does nothing > No Download Mode > Don't want a new phone > Don't want to take it apart and try to short circuit anything if possible. LOL.
I am totally stuck here. I am done alot of work and even helped friends and family out with their devices over the years. I am just not sure if I need to consider it a done deal and get a new phone or maybe one of you guys know of something easy and obvious (please let it be the latter) I am missing. Thanks for any help you can offer. I Will be standing by.

I haven't thought about flashing a bootloader. How would I flash the bootloader if I can not the phone into either DL mode and or TWRP doesn't do anything either? Is a bootloader file just a flashable file like any other .zip file?

The first one I can not do as I do not have any knowledge at all of Ubuntu, Linux, or any of that. It would take forever to get a working knowledge of that software in order to get things going again. I would probably just have to either take it to a cellphone repair shop or get another phone before I could do the first link.
I have not tried the second one but it is a viable option. I was looking at it online and trying to talk myself down from having to do that. I would reallllllllly rather not have to take my phone apart if I can keep from so that's kind of what this post is all about. Just trying to see if anyone knows of ANYTHING else before I go taking apart my phone.
Can you describe more about "twrp doesnt do anything"?
Does twrp boot up?
Can u see/wipe partitions?
Can u install any rom in twrp? Does it finish?

TWRP boots and I can go into wipe, advanced wipe, and format data and it says it's successful. I can use file manager and move items back and forth from USB OTG. If I try to flash anything it just reboots TWRP immediately so I can't install any .zip files at all.
My guess is that your bootloader is damaged.
The only option i can see for you is that Ubuntu thing i shared with you. So, lets stop acting lazy and do what needs to be done. Dont scare since there is nothing to loose. LG G2 is unbrikable
Booting up ubuntu or any other linux os is so easy. And there is nothing much to learn. Trust me.
Go to ubuntu website and download their newest iso file. Burn it on dvd and boot it up. You dont have to install it, just choose "live mode" and it boots up. Just like that. Then yiu can proceed with tutorial mentioned above and it shouldnt take more than an hour from you. Its all typing some commands in terminal (remember CMD in windows!).
Just make sure to download the files mentioned in that tutorial before proceeding.

First of all calling people lazy is not nice. I'm not lazy I am trying to play it safe. I wouldn't want to brick it to the point to where I don't even have recovery and it can not even be charged any longer. I have Ubuntu on my desktop upstairs. I have used it a little. It's not that I am completely ignorant to Ubuntu I am just a total novice. Also the issue described in that post doesn't exactly match my situation. I am not in a black screen. It's more like a bootloop that I can not get out of because TWRP is not doing what it needs to do and I can not flash TWRP a ROM or get into DL mode at all. Also that post says,
"VERY IMPORTANT!!!!!!! You must use the img files that correspond to the ROM you have installed before getting the problem to avoid breaking your phone."
I don't have a rom on my phone soooo...
You didn't answer my question well. If on TWRP you can finish installing rom without any error, and you keep coming to twrp after restarts, that's another situation. Try this:
http://forum.xda-developers.com/showthread.php?t=2451696
But if you cant even finish install in twrp (twrp gives you errors or just restarts before giving you "successful", either you have problem in rom you try to flash or you need to build everything up from start.
That lazy thing was for encouraging you to do it.
And you cant brick your device. There is always a way on G2.
For img files: find them from last stock rom that was working on your phone.

D802: [720] Fastboot Mode Started

Hi All,
I realise you guys must be sick of these kind of posts but just thought that one of you would be able to point me in the right direction before I do something else wrong!
I was rooted on d802, Cloudy 3.3 with TWP 2.8.6.1 installed. I was trying to get magisk to work but after flashing the various zips etc I left my phone for a few minutes and a toddler came along and swiped the install superSU prompt on TWRP that comes up before rebooting :/:/:/.
So now I am stuck in this "[720] Fastboot mode started". When I plug it into my computer I get a few other things popping up and on device manager it comes up as "Android Bootloader Interface", Device type Kedacom USB Device.
Before messing around with all these things I made a full backup with TWRP so if I can just get back to that I am hoping I will just be able to restore it? At the moment I am unable to get to recovery mode, it just keeps rebooting quickly showing the LG logo and proceeding to fastboot mode. I have tried the holding down power and vol d button but it happens so fast and doesnt seem to do anything.
Where should I go from here? There seem to be a lot of different methods and various things, the more I search the more ways I find!! What is best in my particular situation?
Also could somebody definitively tell me if Magisk will work with cloudy 3.3? I can find no mention anywhere on the internet of someone saying they have done it/got it to work.

Good luck!
Thank you very much for your prompt reply !!
I kept trying with the power and volume down and managed to somehow get back into recovery, and then I recovered using the backup!! All back to normal now !
I've since updated to the latest twrp and that all went smoothly aswell.
Any word on whether magisk V9 will work with cloudy g2 3.3 ? I'm tempted to give it another go...
Use the unsu zip , uninstall xposed using the zip , then flash magisk , phh superuser and finally the cbump. I'm really tempted to try again but not sure if it was doing that , that messed it up last time or if it was twrp trying to install super su (Im quite sure it is probably the latter though). Any thoughts ?
EDIT: incase this helps anyone else, I think what I did was to keep the power and vol down held for a long time , if I remember correctly it seemed to cycle a few times through logo and then the fastboot screen until it finally switched off. Prior to this as soon as I thought it was off it would just start again. This time though it went through into the factory reset screen and then recovery.

OP6T won't boot

Hi all,
I'm facing a really strange & annoying issue ... I'm running latest OOS version, unlocked bootloader, TWRP installed, root via Magisk. & substraturm theming.
I uninstalled all my overlays, rebooted my phone and boom, here the deal : my phone won't boot at all.
I tried to press the power button for something like 30sec, nothing, not even a vibration.
I tried to reboot in recovery/fastboot via the volume keys + power button, nothing happens.
I tried to charge the phone, maybe I was running out of battery..? Nevertheless, nothing happens ...
I tried to reboot into recovery via `fastboot boot twrp-xxx.img`, but fastboot can't detect my phone as it stay totally powered off....
Anyone get a idea about the how to fix it & how it happend ? It's really annoying as I'm in travel and I don't get any extra phone ...
Thanks all
edit: Ho yeah, I'm running linux & I don't have access to any windows computer

You don't want a custom ROM. Fingerprint sensor doesn't work under custom ROMs at the moment.
Also trying to charge with the phone off with Magisk installed will give the perception of a brick.
You will need to jump through hoop to get the device to boot again.
Don't ever try to charge with the phone off with Magisk.

What are you talking about. I charge all the time with my device powered off and I always have magisk installed and never got the perception of a brick like you describe it. And custom rom are all extremely stable for this device fp is the only issue and it's got work being done and its already working on custom in the test groups on telegram. And they is always face unlock which is better than fp anyways.

Actually not. With the latest, I guess one or two releases of Magisk this is now fixed. Magisk forces something other than a normal boot from a patched image. My Essential had the charging while off for a year and this phone up until I installed the latest release.
So you are correct current version of Magisk does not cause the issue.
Another thing which is strange.
Since that bug yesterday I can't connect my phone to the computer to browse the internal DD.
Instead my file explorer (on the computer) display me a unknown dir in which I've got some sh script & window exe (I think they're there to install the op drivers).
No one get a idea of the why & how to fix it to go back to the OG behavior ?

That's odd.... It sounds like a driver issue with your computer more than anything. BUT, do you get an option to change to file transfer mode from your pull down menu? I had an issue where it wouldn't even give me that option, and what actually worked for me was to plug my 6T into a USB 2.0 port on the BACK of my computer. Try these things out.

Yes I get the option to change to file transfer mode. My computer only got USB 3.0 port, I'll try to connect it to a 2.0 when I'm back from my trip. Thx for the tips

- can't test usb2 on linux

Odd. Yeah these newer Android devices are just weird like that! I've been told the Pixel devices are just as finicky as the 6T and I'm sure others out there are as well! Glad you're able to get a connection on Windows though! [emoji106]
After 2 month or so I think I found the reason of the bug : tremble !
The bug occured since I did the last oxygenos update (at the time) - maybe it came from the fact that the update was installed on the second partition !
I gonna try to make the new oxygenos update (which will be installed on the first partition) to ensure that. I'll come back here once it's done !
It was that ! After a update to the last OOS (which was installed on partition A) I can finally access my internal storage from a usb 3 on linux

tmobile s8 boot loop-ish

hey all,
Saturday morning a wake up to my alarm on my phone (SM-G950U T-Mobile Stock since new) and turn off the alarm and proceed to check email and scroll social medias. A few minuted later phone turns off and starts boot looping. Occasionally it would boot to home screen and i could unlock it but then maybe 30 seconds later it would start boot loping again. Now it either just boot loops or boots straight to recovery . I have tried flashing current firmware in case it was corrupted and i have tried accessing it through ADB. I know for a fact USB debugging is on because I just used abd to pull wifi passwords 2 weeks ago, but when I try to [ abd devices] if comes up as unauthorized and I cannot proceed. I know everyone will suggest a factory reset, but I am hoping someone has a trick for extracting files. I dont care about most on my phone, but I would like to save the pics from my GF and I trip this past august. Apparently I didnt have my photo library set to sync to cloud -_-
thanks

update: it appears there is a pattern. it boot loops or boots to recovery (after a blue failed system update screen) 99% of the time. the 1% it boot fully and then crashes is only when battery is 0% . it for some reason is only trickle charging and isnt getting enough juice when it does boot fully to stay on . But if i leave it charging a while it will then only boot loop or boot to recovery. Strange...any way I had enough time this past boot to reauthorize usb debug.....wish me luck with adb
....nevermind. still shows up as unauthorized

Ive had similar cases happen with older models. May be time for a battery. They will do crazy **** when the battery crashes. When you flashed stock firmware you lost adb authorisation. Need to get the system back first for that.

Cheapest fix in my opinion. I saw another thread a guy dropped his. Now detects 9008 how to fix. More than likely a phone wont just not boot. Or lose programming unless a hardware issue. So if it was just running and quit. Not modding stuff really. More likely than not its gonna be some form of software. But hardware.

Replaced Daughter board and battery. No improvement :/ bummer
the only time i can get it back into recovery is after a "successful" flash with odin. by successful i mean that it says it worked but it just continues to boot loop or boots to recovery. attached is a picture of the info i get in recovery every time. hope someone can shed some light in the issue. im using my old phone so i dont feel pressured to call the data a loss and try a factory reset just yet....my old phone is a POS though

Yea some one tried to root it using the edl safestrap thread. Only wsy to fix it is filled the steps and reflash jrkruses pie rom. One of my mother boards are in the same state. That's the only way dm verity fails. Is his rom method.
There's some easy to flash a cache wipe in Odin but I hadn't found it yet. I have 2 mother boards and one is identical. I flash this stock and lose download or recovery. but the errors you show are only from doing that edl safestrap
Ill be honest..i have no idea what you are talking about. Ive messed with the software with previous devices and never heard of safe strap. This one has been bone stock since I got it from Tmobile and i haven't attempt to flash anything until i had this issue. never tried to root it

https://forum.xda-developers.com/galaxy-s8/development/root-t3904613. This thread can help you at least get pie back up and running. I wouldn't mess with no more. I haven't had much luck with mine. But I did get it booting again
