What if no unbricking methods work?

I've searched, researched, and tried most every method I can find or conceive of. But my phone (D800 stock unrooted will not stay alive long enough to do a factory reset, won't mount, won't communicate in download mode enough to replace firmware (it seems that it returns nulls for all requested fields). I was once able to get to the login screen before it crashed, but now it tries to update files, and crashes anywhere from 1 to 20 of the 100+ files it's trying to update. It seems to crash pretty quickly trying to do a factory reset. Sometimes it makes it to displaying the Android image, but usually shuts down before that, after about one second.

I'm a linux user, and if I could get it to mount, I think I could resurrect it, but it won't mount. I believe it is in charge-only mode, to make matters worse. No way to reset it from the phone. I also a Windows version in a VM for running various automated programs. I have the drivers working (except MPT, for some reason), and LG Flashtools acts correctly until it's time to do the actual update, and then it gives an error because (it seems) it is getting nulls for all the info fields from the LG (imei, id, etc).

This all happened after I did something that, looking back, was probably foolish. I wanted to unlock the phone from AT&T, so I got an unlock code, and instructions to put in a non-AT&T sim card. So, I had just switched to project Fi on my Nexus 5X, and tried using that sim (in a nano to micro adapter). I was curious to see what would happen, and didn't think it would destroy the phone. But, it did not like that. I do wonder what would happen if I put in a compatible sim, whether it could reverse the damage? If it's possible, I'd invest the few dollars for a sim.

I'm just about ready to give up. Can anyone suggest anything new?

PS I do charge the phone, so that's not the problem. Although, it's sometimes hard to get it to even charge, which makes me think it's not always off, just appears to be. Sometimes, I plug in the cable and it starts up and charges normally, and other times it does nothing. Also, sometimes it will be charged, turned off (it appears), and the batter will be dead the next day.

Cannot Write Files on Spring LG G2 As Root

Hello, I'm having some trouble with following step #3 in this thread:

http://xdaforums.com/showthread.php?t=2655133

Where you're supposed to copy the files to the carrier folder. I've tried everything with the root browser, using Total Commander 7.55 and everytime I copy the files over, it looks good.. then I reboot and they're gone. When I copy them within the root browser, it doesn't give me any error that the files couldn't be copied.. it simply says 'pasted 19 files successfully'

I downloaded the mount /system app from the play store to try to remount the system as rw, but that hasn't worked for me, even when selecting the option to make the system folder rw upon boot.

I didn't flash a ROM, as I only saw one in the sprint LG G2 forum

phone info:

model: lg-ls980

android ver: 4.4.2

Kernal ver: 3.4.0

Build: kot49i.ls980zvc

Software ver: ls980zvc

Trying to get the phone to work with straight talk. I appreciate any help on the matter.

Hi guys, been thinking about buying g2, before doing so, i have a concerned with thermal throttling.

I know all device does, but does g2 throttles sooner than most devices? Thank you
[G2 Q&A, Help & Troubleshooting] XxZombiePikachu:
well I can speak from personal experience I put my device through a lot and I mean a lot of thermal struggles which is mainly because I test the dolphin emulator(play gamecube games/wii games are starting to get some fps but still ways to go) and I can go for about 45 minutes the device gets super hot but performance doesn't struggle that much by the 30 minute mark I can still get about 15-20 fps from about 30-45 fps in beginning so I would have to say that the g2 handles thermal throttling really good compared to some of my past devices(s2/s3)

[G2 Q&A, Help & Troubleshooting] XxZombiePikachu:
The only thing that gets tripped is a file on the phone which reports a rooted flag for when you are in download mode, using the back to stock method removes this flag and you are able to use warranty, but I have noticed some of the kit Kat kdz/tot files after being flashed if you enter download it would show rooted even if it wasn't but there is a thread in the general section with a fix to make it show unrooted on kk even if you are rooted(which you need to be in order to use the fix)

Does sombody know if I can downgrade my LG G2 D802 from custom ROM 4.4.2 (Paradus HD) kitkat to a custom OR official 4.2.2 jelly bean?

Hi, i have an D802 Europe open Lg g2, rooted.

Clockwork Recovery v6.0.4.4 is installed on my phone. Android version is 4.2.2. Using stock rom.

Recently ive receive a FOTA update for my phone, ive read that i cannot update my phone if it's rooted so i used SuperUser Elite apk to temporary unroot my device to install the update. i also checked the box " OTA survival mode". after i tried to install to update, phone boots only to clockwork recovery mod and my phone wont boot properly. I tried to factory reset and restore my cmw backups, but no luck.

What i need from the good people of XDA is guidance. What should i do?

In my searchings for solution i found this threat http://xdaforums.com/showthread.php?t=2451696&highlight=cmw - will it work for CMW recovery as well?

Or should i try to go back Stock Firmware with this guide? http://xdaforums.com/showthread.php?t=2432476 its a guide for kitkat 4.4.2, it will work for my version? (4.2.2)?

Please guide me on what to do in order to fix this guys, im not sure what i should do and im been careful not to brick my phone.

I would really appriciated any help ASAP since im stuck without a phone at all.
[G2 Q&A, Help & Troubleshooting] XxZombiePikachu:
Well first thing is to clarify you can ota with root, the only time ota is a no no is when you have custom recovery. Anyways the firts link you provided should work with the adb method(I have done so with philz), if by any chance it doesn't work then your only option is to try to get into download mode and return to stock

Thanks for the quick reply, so thecubed's thread works with cmw recovery? or should i install twrp over cmw? if so, can i simply flash twrp using cmw? ( flash zip from sdcard)

[G2 Q&A, Help & Troubleshooting] Sunandroid:
This sounds like a hardware issue to me. Something like corrupted memory I imagine. I doubt it's related to the SIM-Card. But you can try to start the phone without SIM and SIM-Tray, as an act of helplessnes.
[G2 Q&A, Help & Troubleshooting] martyfried:
Thanks, there's no sim card in, and I did try without the tray, too.

I'm sure it's related to trying the foreign sim card, but it could be something to do with the use of the adapter, perhaps. Not sure how robust the connector is to a mis-aligned sim card, but I would think it would have to be fairly forgiving.

But I'm not really sure what the sim card would do, exactly. Like, does it modify the system software in some way? I'm guessing it probably does, and it probably crashed because it was the wrong phone. So if I could somehow get access to the system drive, I could copy the partition info into it. Problem is, I think it crashes before I can do anything. I can hardly get it to go into charge mode. I think it might crash shutting down or something.

Perhaps it's the rare case of a true bricked phone. I'm glad I have the Nexus now, but I really wanted to give this to a relative.

PS. I'll take a look at your post I see in your sig "Nothing Works anymore". Might be something there.
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Well. Can't do anything if you are sure about it. But I still doubt it. Only thing that could be is that the adapter or whatever created a shortcut, but that's almost impossible.

It's indeed possible that it loads an app from the SIM to the phone. But that shouldn't affect the bootloader at all. So I don't think it's sowftware related. But anyways. Keep trying and show me the opposite! Would love to see that. ;D

Yeah I see. Congrats for the nexus btw. ;)

For the guide working in my sig, you need at least qhsusb_bulk in windows device manager. You can also use srk tool for the G2. It basically does the same thing as I explain in the guide.

As last step you can try to short the capacitors to enter the qhsusb_bulk mode (from where it should be an easy one to recover if everything works properly):

Everyone shorts different pads, but the results seem to be the same.
[G2 Q&A, Help & Troubleshooting] martyfried:
Thanks. It's a real mystery so far. It seems like it's getting worse - I haven't even been able to get it into battery charging mode. I suspect it may be crashing just trying to shut down so it doesn't totally turn off. If I turn it off, sometimes it starts up when I connect the cable, but I think it dies now. But if I try safe mode, it gets to the point of trying to update a lot of apps, and makes it through a few before dying,

Project Fi has that feature of switching carriers, so I wonder if it installed something to do that, and screwed some partition up.

When I connect it to windows or Linux, it gets recognized, and has a mfg ID and device ID - different device IDs depending on whether it's download mode, normal, or one other that I can't recall right now. I've gone through the factory reset (recovery) about 100 times, but it never seems to finish.

I'm pretty good at troubleshooting and repairs, including electronics in the past, so I hate to give up, but I'm reaching the end of my rope. I'll try the shorting of the capacitor and see what that does. Maybe it'll at least let me charge it up for some more tries. :(

Searching for a sensei

Respect to all the experts in here

Especially the noob friendly

I recently purchased an LG G2 ( yes i'm not up to date ) from a dude in the market, it runs well actually no particular problems.

However when tried to update the android version from jellybean, I got this message saying ''authentification error, please try again'', samething happens when I try to update PRL+profile+unlock UICC, the only thing updatable is LG software ( on system update ) .

There is also ACTIVATE THIS DEVICE (self service) , it sais ''sorry we experienced a system problem...call customer care'' and of course I should precise we don't have that in my country, at least not the one mentioned.

Now the phone it self says ''SPRINT SPARK'' when I turn it on , has this application ( which doesn't do much when I run it except blue screen ) that says kingo root, so I guess it is rooted , even though I tried an app that checks the root , but it says '' this phone isn't properly rooted ).

I've read and viewed lots of videos, some say to unroot it and use a stock room ( something about original rom ) , some suggest I use CM and a custom room, etc etc..... but the truth is even though I have a basic knowledge, I don't think I can do this on my own or even being able to tell the risk ( it coast my whole paycheck I swear)................ so I humbly ask of you dear experts for guidance !!!!!!!!!!

Searching for best battery life

Hi everyone,

I am a fresh owner of a wonderful used LG G2 D802 32GB, with rom stock 5.02 (v30d) and never rooted/flashed etc.

Now I have used the phone for 4-5 days, and I like it a lot, but the main reason that made me buy the G2 was

the great battery life... and at the moment, with my use ( almost no wifi and a lot of 3G Data) the battery life is only "good".

So, I promise: I have searched a lot before... but I have found only very old answer to my question. (6 months and older)

And the question is: In order to achieve the best battery life, even losing a bit of performance (I'm not an antutu guy!)

what combo Rom - Kernel do you suggest?

My use: almost 0 gaming / lot of web browsing - mail - whatsapp - calling - and the usual 30-40 apps.

I need: Great battery life, bug free (or close), double tap to wake, working irda, camera and gps.

I don't need: Overclocking / hyper benchmarks / cool graphic... I always install Nova prime with the same icon pack.

Thank you very much in advance.

Modified Software status with no firmware update/ download mode

Hey guys wondering if someone can help me out. I've been trying to get my G2 back to stock since it was stump rooted and then not unrooted properly. Sadly at the time I was less experienced and had no idea what my friend was doing. So I'm stuck with my phone software as modified status. In the process of trying to fix this I figured out that I cant boot into the firmware update/download mode. I've done the whole factory reset and factory hard reset to no avail. When I push the volume up button and then plug in the USB I wait to let go and then the screen goes dark like its going to go into download mode and then the LG symbol appears again and boots normally. Can't figure out what to do and I can't seem to find any forum posts that can help me.
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Did you hold the vol+ button till the very end?

If you still have root you can use autorec to get a proper bootloader and a recovery. With the bootloader comes the download mode. It might be that after autorec your android won't boot anymore, but you have a recovery and a working download mode for this case.

Make sure you flash the right files for your model.
[G2 Q&A, Help & Troubleshooting] Bender415:
Yeah I've tried holding it down for serveral different variable lengths of time. Everytime though the LG symbol appears again and it boots normally. Or if you continue to hold it down the LG symbol appears then goes black and then appears after a few seconds and then goes black and continues to cycle in that manner. I'll have to re root it and try autorec but at the same time the main thing I want to do is go completely back to stock wiping everything so I can reroot and actually use an xposed installer with greenify and other things to fully take advantage of my phone's capabilities. It's 2 years old and I recently swapped out the battery and it still has the worst battery life I've ever seen. Also it was getting super slow anytime I had data turned on. So you can imagine why I am wanting to fix this the way I am. If there is an easier way I'd love to know it. thanks for your help.

then on playstore i installed autorec lollipop for my variant. opened auto rec and it backs up the recovery and it tells you its ready to flash just click on flash twrp and when its done you have twrp recovery...

now you must use blastagator twrp with thermal to protect your screen.. download zip. then go into recovery, i use link2 sd it has reboot into recovery with one click or use the button combination... once in twrp flash blastagator and go back to main menu and reboot but click recovery to reboot into recovery.. then check on top right corner that says 2.8.7.3. then you are all set.. to flash stock roms if you want to flash cm or aosp roms... flash bootstacks

you can use hybrid for stock and 5.1.1 and cm13 6.0

you must flash bootstack first then reboot into recovery again.. then rom and gapps if its aops or cm12 or cm 13.
