Keep in mind, this method is not confirmed working if you're running android 2.3.x [ Gingerbread ]. So do not use this if you're running it. Also dual sim ones aren't supported from what I see it tempers with the phone, I haven't tested it but many have reported it doesn't work on dual sims.
Lets get started shall we? Firstly I have gathered up some useful resources that will help you get started. Make sure you read this guide first, from top to bottom. Then continue. As you must have a clear understanding on what you are going to attempt. If you have any queries don't hesitate to ask on the thread itself.

I have performed these exact steps and have successfully unlocked my bootloader and rooted the phone. So if you're worried. Don't be. After attempting this I haven't noticed any issues either.
Okay, first of all you will need to download Unlockbootloader ---> View attachment unlockbootloader.zip
Once you have downloaded the said .zip extract the .exe file inside the .zip to your desktop.
Continue by turning on USB debugging on your G300. if its already switched on then skip the part below..
Go into Settings>Developer Options and tick the USB Debugging option.
Once its switched on, plug your phone to the computer using a USB cable.
So far you've downloaded Unlockbootloader, have switched USB debugging on, and your phone is connected to your PC.
Now run the .exe file you have just extracted. Click "Root" and let it do everything, it will prompt up with a few warnings saying don't use your keyboard because CMD is running.
Once the setup finishes, your phone should be rooted.
Head into the app drawer, and if you see "SuperUser" you're now officially rooted.
Reboot your phone to finalize the rooting and exploits.
Ok, now for the bootloader.
Once your phone is on, and connected again to the PC with debugging mode on, run the .exe file again and this time click "Unlock BootLoader".
Wait for it to do its job, once done reboot again and you now have a Stock Rooted and Bootloader unlocked ICS phone.

I am trying to root my Huawei g300, (from vodaom uk, unlocked) have followed your guide BUT I Have No usb debugging option anywhere under settings. Why? Still awaiting official ics update from vodaom / Huawei, impatiently.

Hi, assuming you have installed the g300 adb drivers, once the device is hanging on the boot logo and you connect the usb cable. You need to wait for windows to fully the load the adb driver before you use the unlockbootloader.exe program.

What you have to do is,turn on debug, then power off device fully by pulling off battery then putting it back in, now you must power on by golding the volume down button and power button at the same time, this should get it to be stuck on the huawei logo screen, now plug in your USB cable and wait for you PC to detect the phone and it should automatically install the devices driver's, one its done the now open the folder and run .BAT files, If you are experiencing problems here's a link for another guide : View

Hi,
After the "Unlock BootLoader", my phone doesn't boot. When the logo appears it stars to reboot again and never goes beyond that.
Any ideas ? Have I killed it ?

Turn ur phone completely off. By pulling out battery then apply the battery again.
Now hold volume down and power button and it should be in boot loader mode. If ur logo is stuck well this is in boot loader if not and it continues well.. idk

Hello krishneelg3,
I have tried a method on http://huaweig300.com but I'm stuck with the problem.
Installing USB drivers/Root/Backup IMEI went OK. Then by mistake I skipped the Step on page 5. Check Baseband and kept continued by Bootloader & ClockworkMod all went OK until the step 10. On page 6. After executing BootloaderG300.exe the phone rebooting cyclically, My operator screen appear for a approximately one second and the phone restarts again. How to resolve the problem and is there any hope to return to official ROM?
Thanks in advance, I really appreciate it.

What was ur baseband and were u running gingerbread?
If u r on official ics then this guide is for u, if not notify me.
PS : If you are running Gb I refer you to look into this guide, as long as your phone can boot into bootloader your fine, and I'm sure it will boot into Bloader mode : http://www.modaco.com/topic/353386-how-to-root-your-huawei-ascend-g300-for-windows-mac-and-linux/

Thanks krishneelg3,
my baseband is 109808, and I'm running GB.
The problem is that I don't know if I'm in a Bootloader mode when I see a pink screen?
When I press VOLUME DOWN + POWER it starts same as when I press POWER, first logoo (in my case picture of my operator) it lasts for about few seconds, then phone reboots and start doing it cyclically.
The other thing is that, when I press VOLUME DOWN + VOLUME UP + POWER, it then turns into a pink screen.
In that state (pink screen), when I plug in my phone to my PC, PC recognize my phone without reading sd card or internall memory.
So what should I do?
Thanks man, really appreciate it!

Guys,
I solved the problem.
I've just followed the instructions in step 5. on the site http://huaweig300.com and put a new update.app (1 KB) and copy it to the dload. After that I've used main dload (ICS folder, aprox abot 600 MB) and everything updated and installed successfully.
Thanks.
p.s. if anyone has or had the same problem, do not hesitate to ask.

hi all
sorry to hijack the thread
I have just got my son an ascend 300 which is locked to vodafone
its on android 2.3.6
the build number is
u881v100r001c02b892
i have a download of HDU88151079V100R001C00B934 which is the ICS but i dont think that will work for my build
ideally i want ICS but dont mind too much waiting.
but i do want to be able to get of all the bloatware.
I guess i need to root to do this.
the link to the modaco site is down and it seems this is for those lucky enough to be on ICS
would i be better off upgrading to ICS then following the method above or would i be better finding a method to root under gb (If so where)
many thanks

OK get the official pics update b927* must be that build.
After its done downloading, extract its contents to your memorycard of the phone.
Make sure the update.app is in the root of SD card .
Then power off phone, remove battery re apply battery and hold the three buttons "volume up, volume down and the power button" until a screen pops up it will then install the stock ics once its done it'll reboot twice.
If only one it doesnt matter.
Setup the phone. Now to install b934 or newer versions use cwm for dazzozos repacks or the update force method. But I advice u to look for help on modaco. Thanks.
Modaco name : krishang3

krishneelg3
Thanks for that by b927* you are referring to a different version of HDU88151079V100R001C00B934 ?
where would i be able to get this from?
so this would give me the stock ics
what is the advantage of then installing HDU88151079V100R001C00B934 ?
Thanks

Your on gingerbread so your baseband Is 109808 and if u flash any b934+ stock using the combinations say goodbye to your phone. I did that to my brothers and it bricked.
So to get to ice you must install b927 version of ics then your baseband will change to the new one *2030* now you can flash any b934+ stocks because you now have the new baseband.
Go to modaco and enter the G300 forums and look at the first dew pages all the info and guides you need. Procedure is simple.

[Q] And I mannage to soft brick....

Hey guys me again, I have been trying since 2 hours to unbrick my 2 days old Galaxy tab s 10.5, After successfully rooting my new tablet I decided to make a back up of my stock system, I used TWRP recovery to do so, after booting successfully on TWRP, I wanted to make sure I will have a clean image, I manually erased every possible thing on my table by selecting every option on TWRP, once done and on my way to reboot, before quitting TWRP warn me that there wasnt any system, and even with this warning I quit. Result I bricked my tablet hopefully "soft", to get even better I remembered that I didnt had a micro sd card on my tablet and by consequence I must have erase TWRP and every possible restore solution, the table get stuck with the Boot logo and thats it... I can get at least into download mode,. I tried Kies 3 but Im getting an error that my device is not recognized and for Odin I do think is connected but I dont know how to use or what to install or what to do. And I don't get it why my program seems so buggy and I can´t select any of those options.
at least I could root my phone easily.
ps: I did try every possible combination to get into recovery mode and is just impossible there is no way.
if anybody rescue me I seriously cant thank you enough I googled around and did search a lot on the XDA forums, I'm now more scared to tweak around and make things worst , and maybe if not to late permanently dammage it.

So the big problem is that after I manually selected every option System etc... can´t remenber but I do know I did wipe out EVERY SINGLE THING, And I did exit even receiving a WARNING you dont have a SYSTEM.... and I did yes quit.... Than to find myself stuck on the samsung logo and being totally blocked since than, I discovered with regret that I actually DIDNT had a Micro SD card and I did wipe out everything including the Restore program if Im getting it right.... I dont know if its already to late and I can go cry on a corner for waisting 500$ in 2 days or is there anything I could do ???, I can get at least into download mode,. I tried Kies 3 but Im getting an error that my device is not recognized and for Odin I do think is connected but I dont know how to use my Zip unofficial downloaded rom and install. And I dont get it why my programm sems so buggy and I can´t select any of those options.

Hey maxal, thx for replying, my English is really not the best, if you think its not understandable I will re edit and try again.

You will need to find and download your firmware from Sammobile http://www.sammobile.com/firmwares/database/SM-T800/BTU/
and use odin to reflash your stock firmware.
Read this too. http://theunlockr.com/2014/08/09/how-to-unroot-the-samsung-galaxy-tab-s-10-5-wifi/
TURNING THE DARNED THING OFF:
Here's the problem. If you are at the Samsung splash screen or boot looping Recovery, you cannot turn your tablet off by just pressing the power button and you can't pull the battery. This prevents you from getting back into Recovery or download mode to restore your nandroid backup or use Odin
So here is what you do:
1) Plug your tablet into your computer (this is important!).
2) Hold down the home, volume down and power buttons until you boot into download mode. Once you are prompted, push the volume up button to enter download mode completely.
3) Now, once in download mode, hold down the power and volume down buttons (not the home button this time) until you screen goes blank (your tablet MUST be plugged into your computer for this to work!). Release the buttons and you will see the battery symbol on your screen. Your tablet is now off - thank god.
4) To enter Recovery mode, hold the home, volume up and power buttons down until Recovery loads.
5) Restore your nandroid backup if you have one.

Thank you so much Maxal I will do it so, indeed the text was terribly written I tried to make it better and more understandable, I read that actually Kies was the way to go for flashing back a bricked device, and odin was actually a risky thing, is that right ?

I believe kIes is for stock unrooted devices and Odin is for rooted devices, I may be wrong. I did get my self in a mess and I was stuck on the Samsung logo and with the help of the forum and what I have told you I managed to get my Tab S to turn off, I then boot in to download mode and used Odin to flash stock firmware again

all right almost done downloading the firmware, could you give me the tutorial you followed for bringing your tablet back to life ? or any good tutorial, Helping me to get out
thx again

I don't know which firmware you should have as I don't know where you are from, but I don't think it should make much difference, the firmware I gave the link for is the UK one.
Maybe someone else can help with a link for the correct firmware for you.

But please keep in mind for the future that the load to your Tab better the original firmware that corresponds to its original CSC Region code. This can help you avoid some of the problems in the firmware flashing. How it may be defined, you can read in this thread:

Hi maxal,
Download via KIES will not check root If you do not connect the tablet to a PC. It only checks the serial number and model type of your Tab for search new updates firmware with determine the correct CSC Region code. You can even download the correct firmware by KIES to your PC without having to connect the tablet and then save the file firmware (this requires some tricks) and flash it via Odin. To do this, you need only enter the serial number and model type of the device in KIES menu Tools -> Firmware Upgrade and Initialisation. More details have here:
http://forum.xda-developers.com/showpost.php?p=58527780&postcount=5
In this case you no need connect the tablet to PC. It also confirms ashyx here:

CM13 Update result: (Soft)Brick

Hi Guys,
yesterday i wanted to update (dirtyflash) my lg g3, because the 2312-Build of CM13 was extremely buggy (Restarts, Blackscreen by ingoing calls, etc.) I´ve done this before about 10thousand times and on 100 other phones, but yesterday after the flash in TWRP the TWRP wasn´t able to delete the cache.
I tried to flash again to delete dalvik and cache afterwards clean, this time it worked. The phone was booting to the PIN-Entry but it freezes - no entry possible.
I want to try flash back an older build, but phone stucks in bootloop - so i have to manually enter recovery to get into twrp. I flashed an older cm13 build 1812 and cache deleting was not possible again.
Yesterday was Xmas so i thought i will fix it today, but on first time when i tried to get manually into recovery mode, the question for deleting all data appeared, but after that TWRP wasn´t starting, just the stuck lg logo again. (Battery was pulled out for the whole night)
Now im not able to boot into recovery mode anymore or do something else. I tried the download mode (Vol+ and then plug in USB) without access.
I cant do something, just look at the beautiful LG Logo - have you guys some advice for me? What could i try?
THX

I have almost the same problem.
Try to charge the battery without starting the phone. After it had 100 percent I was able to start the recovery..

When i plug it in to charge, after 20 Min. fastboot starts automatic!? Is this normal and will the battery get charged in fastboot mode?
I don´t know if it was on 100% battery after about 1 1/2 hour of loading, but the same issue: It asks me for entering in recovery but didnt start TWRP, Logo Bootloop again.

I tried to fix it with adb/fastboot, but no chance. I get the phone listed, but its offline.
Tried to reboot to recovery with the recovery.img (TWRP) and reboot recovery - it starts twrp but stuck on twrp logo.
Somebody help :crying:

Same thing for me on cm13(18-12) with flash other kernel,i get LG Logo and "Security Error" message under it,i couldnt solve it,then flashed stock rom(.kdz) via usb-download mode and solved problem.

Same problem here.
First the phone freezed a couple of times. Pulled the battery out. Then tried to reinstall, the reinstall failed for some reason. And from then on... Stuck in the LG Logo. When I try to charge the phone the battery icon appears but doesn't show progress.. after many be 20 minutes the phone boots in "fastboot mode", but even then when I connect the usb cable it says that the USB cannot be enumerated.
I managed to take some log from the devices right before it freezed the last time.

Flash stock would be great, but i have no possibility to enter usb-download mode. Just Fastboot - and just with offline device.
I can start TWRP with the newest TWRP in the ADB Folder as "recovery.img", and then reboot recovery.img - but it get stuck at TWRP-Logo. The phone react to the commands.
I would need a solution to do a factory reset or flash stock with adb/fastboot and offline device.

same here.

Please read carefully before you try and flash something - both methods requires USB-Download-Mode, which is actually in my case NOT possible anymore.
Today ive got time and will try a few things, if it works i let you know.

Today ive got time and will try a few things, if it works i let you know.

i've tried both KDZ method and TOT method - both not working cuase my phone can't go to download mode and does not recognize correctly in PC.
but this guide: http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
seems to do a lot more than this guide: http://forum.xda-developers.com/showthread.php?t=2785089
you sure it is also pointless?
you all should also follow @maxauvy posts in this thread: http://forum.xda-developers.com/lg-...ogenmod-13-0-nightlies-lg-g3-t3257951/page102
he claims he had this problem and solved it!
he is writing a guide right now!

Nr. 1 of your link could work, but it´s the last method for me i will try because i have to open my g3 (de-virgin it) :laugh:
Nr. 2 isn´t a option, look at point 4) Enter to Download Mode and plug USB into your PC -> Download Mode isn´t possible on my coma g3
I think this is the "easiest" solution (Click here) (based on your 1st links solution - but without opening the phone), but i´m not sure i have to donate for the files.
I´m still reading the tutorials and will report how it worked for me.

Hi there,
I just posted a how-to, as @omer323 said above. Glad to see there's a dedicated thread, instead of "polluting" CM13's one (even if it's CM13-related, I think).
The guide I wrote is there, we can discuss about it right here if needed.
If I can help, let me know

That was the hardest and longest thing i ever done with an android-phone but hey, it really worked, my g3 is alive :victory::victory:
Here are some "impressions":
My motherboard is a little bit different, but i tried it with the 2nd pin and it was magic! Look here
Disassembly the g3 was a little bit tricky-er as i thought, but i´ve done it, maybe some help for somebody to see the parts you can take off, see here: Parts 1
Parts 2
You have mentioned in your guide, that you´ll need a 3rd hand to plug in usb while pointing at gnd and the pin - in my opinion a 4th hand would be better - but i´ve created a "connector" to be able to fix it on ground and on the other side a needle, to be sure just to point just the pin2-solder-point, look here: SelfmadeConnector
Flashtool v1.8 didn´t worked for me (on Win10 64-bit), tried to flash instead .kdz with FlashTool2014 with success. Before that i had to lower the com-port to port 6 - i dont know why but it didn´t worked with port 41. for example com6
:fingers-crossed::good: I wish i could click on "Thank you" twice
One thing left:
I am rooted on stock with TWRP running but no IMEI. (IMEI: 0)
I´ve got an efs-backup of my g3, but no .img-file just folders with about 2GB Data in it - about ~20 .win and .md5 files.
Can i restore the imei and the other stuff i´ve lost through the wipe with this files or should i just restore the imei like mentioned in your guide? (What if I don’t have any EFS backup?)
Thanks for that guide and adventure

Those files you're talking about, how did you get them ? Using TWRP ? If so, just use the "restore" menu of TWRP and point to the directory where your files are stored. It should recognize the backup.
Happy to hear that you've been able to unbrick your phone

Thanks for that advice.
Yes i had these files from a TWRP-EFS-BACKUP, but i wasn´t able to point to something, the list in twrp/restore was just empty.
I moved the files in the TWRP Folder on Internal Storage and voilá it listed the Backup and i was able to restore everything: IMEI, MAC, ....
My G3 is right now not just back from coma, its like re-born :fingers-crossed:
Thank you mate!

This hasn't happened to me but just curious if it has been tested to skip the erasing EMMC part and just rewriting each partition with LG Board Diag?
Partitions to write would be:
PrimaryGPT
modem
aboot
rpm
tz
laf
recovery (I'd replace the stock recovery bin/img with a TWRP img file... this way you can just boot into TWRP after writing everything)
dbi
sbl1 (write sbl1 last if possible)
then boot into TWRP... flash the latest modem/rpm/tz combo required to CM 13... then flash CM 13, gapps, etc...
if you still get stuck at boot up... boot back into TWRP and hit the Wipe button > swipe slider to factory reset data.
I ask because I'm sure there are some who haven't backed up their EFS... this might be a way to avoid that? Of course.. depending on what parts of the emmc were messed up... it may be possible a full wipe is still needed like the guide above mentions. But any chance at avoiding that step would be ideal in my opinion.

maxauvy's guide worked perfectly for me!!

Need modified .tot for LS980

Hi everybody, is there any one who can give me a link of .tot modified file with hex editor, I flashed my phone (LS980) with wrong firmware (D802) and when I try to flash it with the right file wich is destined for LS980 the flash tool consider the phone as a D802 model, I tried all methods I found on XDA to restore my phone but nothing done, my phone still brick, and the only way to flash it now is to modify the .tot file with a hex editor soft, if there is someone who can give me a link to that file, or to show me the exact line to modify in the file and which hex soft to use it will be a great help for me.
Thank you in advance (Please try to give the help I demand, because I tried every methods)

Hello kakah2011, First of all i'd tell you to calm down its gonna be alright. secondly can you explain briefly the previous version of software you were running. Android version and the software version, if you could mention would be of great help. And did you flash D802 rom yourself, as if it were running LS980 previously or did you buy the phone already flashed with a fake D802 rom. I can guide and provide you on how to resolve the issue but first i need to make sure which partitions are flashed to your phones memory currently.

just relax. i had exactly the same issue and it got sorted out. My phone(hardware ls980) came with a fake 802 software on it. So i assumed its a 802 and flashed 802 roms on it till it completely got screwed up. the touch went crazy and the phone got into a auto restart loop.
I have the edited file, but i dont know how to give you a 2.5 gb file. Any ideas how it can be shared.
I edited the original file using flexhex. You just need to change the first instance of the word LS980 to D802. the trick here is that in hex editor format when we replace L with D , S with 8, 9 with 0, 8 with 2,0 we replace with a spacebar. The last parts a mistake. 0 should be replaced by a blank and not a spacebar. Copy a blank from nearby and insert it. or try a 00 value. I dont remember exactly what i did. but my mistake was that i was replacing the 0 with a space bar.
after the format, my phone stopped getting into the download mode. Instead i got stuck in some fastboot mode which was getting activated by using the volume up key while inserting the wire(before this, i was getting download mode in volume down+usb wire insertion). had to struggle a bit to get the phone back to download mode. I used something called adb tools to get this done. If you konw these tools, its just a 2 min job.
After that i reflashed the original tot file of ls980 and the phone started working great.
if you need anyhelp, call me if you are from india on 9700000678. Else pm here or email on [email protected]
dont forget to thank me.

Thak you Mr, I think that the previous Firmware before I flash it was a LS980 (4.4.2 or 4.2.2), and I think that the version that I flashed the phone with is 16GB, and I can't use adb fastboot with PC to because it don't recorgnize the IMEI and the only way to restore it is the download mode (No Philz recovery) and I must notice that the screen is not normal (when I push it in an area it moves in another), I think that it's bricked for ever!!!!???

The .tot can only be flashed in download mode, on a serious note i'd suggest you here to give your phone to some expert it wouldn't cost you much. But if you'd like to follow.. download mode can easily be restored using the method in the link i just provided earlier. When you get into download mode only then your rom can be restored.. btw please follow as instructed cause if something wrong goes here eg flashing wrong image in fastboot or wiping all at once.. could lead the phone to hard brick and would cost you double as much later to get it fixed. My personal suggestion is to pay $15-30 for this operation and get it over with.. do you have any suitable repair shops in your area?

First I want to thank every one who helped me to restore my G2(especially Krunal Jain who shows me the first step which is the key), finally you've just to download the LAF file and flash it in order to get back download mode then you can flash the .tot firmware of the LS980.
The prbleme now is that there is no more adresse MAC when entering to Wifi settings, and also Cellular network, I guess that these two things need a lot of search to restore them !! Any suggestion??? THANK YOU GUYS

Hello brother
I fixed mine yesterday, i ll tell what to do
If you want to get access to download mode, just remove the buttons connector ,then that metalic plat that its glued in just to get access tothe ic chip and motherboard , of course to do this u need to takr off the baterry and all connectors, once u takr off yhe buttons reconnect every connwctor except the one of buttons and baterry
Thrn connect the the phone to the pc by using a usb (without baterry) then u need a liyyle screw driver or a wire to short the capacitor c5000 and c5004, keep trying till u heard thr pc detect new device named qhusb
Great , for that you need to download srk tool 2.1 just google it
Then selectfix utility then unbrick qhusb and select the correct drive
It will flash : haf, boot , aboot
Thats good for now ur download mode is back to life
Then for ls980 u need to install stock tot file (ls890zv7.tot) flash it with lg flash tool use manual mode u need a dll file (lgls980_20130904_lgflashv151.dll) download it on google... i ll send you links later hiw to do this,im using my phone
Once finished , ur phone is back to life but no signal
Easy ,just need to root. Then install twrp recovery
After that u need to install via recovery mode the (ls980stockuniversal to d802.zip)
And u re phone is getting signal and being fixed
edit: here the tutorial links that helps ya how to do everything
1- to get your phone alive ( to be detected as qusb_bulk)

Trouble rooting tmobile g4- phone disappeared from devices after OEM unlock

I found the guide to unlock downgrade and root 20i, but since i was already on 20i i figured id just skip to the unlock part.
ADB connected.
Got the oem unlock to work flawlessly, tried to boot TWRP, and it said file sent, cannot boot, file unsigned (or something similiar, can copy paste the actual text when i get off work tonight)
I got annoyed and just booted the phone normally and it worked fine and is unlocked-
But cant get the phone to show up on adb again.
Maybe try the universal drivers? Seems to hang on the drivers- the laptop has them installed but the phone doesnt know that they are and keeps asking me to reinstall (which doesnt work)
Any ideas?
Should i start over,upgrade the stock rom and then downgrade, like the directions actually say?

The LG driver you've installed on your laptop is most likely no longer functional for the phone. If it shows in Device Manager when you're trying to connect it, uninstall it (mine didn't work either after unlocking/using FWUL, or something else, for whatever reason).
Once the current driver is uninstalled, turn off your computer, plug your phone in with the USB cable and then turn on the computer and let Windows install the driver now (It worked on mine).
See the attachment below for a screenshot of the current driver for my LG G4 that is working completely.

I got it to show up, but I've realised I have the motherboard issue common to G4's.
The phone hangs at 'bootloader unlocked' lg screen.
Hope the seller will give me a refund or exchange.

It may just be a 'soft brick' you've encountered, in which case you should be able to it overcome relatively easily. First thing to try, is just unplug the phone and take out the battery. Put the battery back in and see if it will boot up. If not, see if you can get into Download mode and flash your rom version for your phone model with LGUP-NEW.
With respect to TWRP, if you can get into bootloader/fastboot mode, refer to this thread: https://forum.xda-developers.com/g4/development/recovery-twrp-3-touch-recovery-t3442424 and follow the instructions to flash by fastboot commands. Use the latest preview version for your rom version, i.e., MM, N or O.

Thanks for the tip. I already tried ADB (wouldn't boot reliably), LG UP (completes successfully- the phone, when LG UP sends the reboot at 75% or so, just hangs on the LG screen forever (though LG UP says it was successful). I also have LG Bridge, but haven't reached any level of success with it either. Luckily all these bookmarks will come in super handy with my replacement.
(Also the day it broke, somehow the camera activated in my pocket. I detected the warmth, but working an assembly line, under a cameras watch, I couldn't pull it out and fix it quickly.

I already tried ADB (wouldn't boot reliably), LG UP (completes successfully- the phone, when LG UP sends the reboot at 75% or so, just hangs on the LG screen forever (though LG UP says it was successful). I also have LG Bridge, but haven't reached any level of success with it either. Luckily all these bookmarks will come in super handy with my replacement.
(Also the day it broke, somehow the camera activated in my pocket. I detected the warmth, but working an assembly line, under a cameras watch, I couldn't pull it out and fix it quickly.
Thanks for the reminder, I'll try to remember.

OK - one last thing to try if you want to try it. Using the power and volume keys, see if you can get into Recovery mode to do a hard factory reset
- refer to this link for the how-to for entering Recovery mode: https://www.androidexplained.com/lg-g4-recovery-mode/
