Nasty Bootloop after Flash on Sprint G2

Last night I installed geefree on my phone from the app store and used it to install TWRP. I downloaded a nightly CM11 and an appropriate gapps. Using geefree I rebooted to recovery (never figured out the button combination to boot to recovery "naturally") and installed both of the zips. This could be where I made my mistake, I installed both at the same time.
Now my phone loops, displaying the LG logo for a few seconds, then shutting off and rebooting before repeating the process. I can't seem to get it to go into download mode or the recovery menu. I've tried power+up, power+down, down+up and each of those while plugging the device in, etc. I can get the device to a hardware key control mode, though it doesn't seem too useful.
How can I save my phone? This forum has been a great resource in the past and I'm very grateful for the many tutorials I've followed rooting other devices. Hopefully you guys can save the day once again!

Volume up plus power is how to access recovery on sprint.
What stock sw version were you on before you flashed cm?
Did you wipe data before flashing?

I was using stock 4.2.2, I believe. I didn't wipe the data (shame on me), a bad habit that I picked up from my first rooted device, the Samsung Moment. It didn't ever matter on that one, afaik. Thanks for the reply!
Edit: Volume up and power whether plugged in or not takes me to the hardware key control mode screen.
Second Edit: http://forum.xda-developers.com/showthread.php?t=2432476&page=35 I also found this thread where someone seems to be experiencing similar issues and they fix it with "LG Utility." Is that a PC application? It's a little vague to google, but I've been trying!

I have a bootloop issue every time i flash a rom i have to wipe all but sd flash roms and gapps the i do a restore from twrp and oly restore my boot image only and they boot no prob

I'm kind of starting to suspect my power button doesn't work at all for whatever reason. I have a lot of difficulty getting the phone to shut down, then it doesn't seem to easily power up. It's a strange collection of problems. Would a Sprint repair place be able to fix this?

If they have parts on hand if not either a swap out or a sendoff

Same problem here - bootloop and no download mode - CWM works! - urgently need help
I guess I have the same problem as InlineFourPower (apart from that my power-button has no problem).
I am stuck in bootloop since I tried to upgrade to Kitkat a few days ago. Now I can´t get into download mode any more, nor into fastboot or anything else. Only CWM works.
From within CWM I can successfully flash ROMs but that doesn´t help, since afterwards I am still stuck in bootloop. It is possible, however, to push files via adb-commands while I am in CWM.
Does anybody have an idea how to go from here or how to get download-mode back?

Device is recognized but can´t be mounted - bricked forever?

I tried a few things on Linux.
After terminal-command "ls /dev/sd*" when the device is unplugged from the computer I get "/dev/sda".
When the device is connected via USB, I get: "/dev/sda /dev/sdb"
So sdb is my LG G2.
So I went on to the next command: "gdisk -l /dev/sdb"
As a result I get: "Problem opening /dev/sdb for reading! Error is 123."
Does it mean that the phone isn´t mounted or what? Now I´ve connected my phone to another Linux machine with the same result. It is recognised (p.e. as sdd), but there is no sdd1. Seems as if it is recognized, but can´t be mounted. Does that mean my device is bricked for good? That´s it?

to get the phone into download mode you have to plug the usb cord in and hold VOL+, so to get this right as I have a case on mine, plug the usb into the phone first then hold VOL+ and plug into usb port on the computer.
it does take a loooong time to power down the phone with the button when stuck in a boot loop, just keep holding it until it shuts off, it will shut off eventually!!
plug the phone in while in download mode to install drivers and set com ports, then unplug before you begin your flash with LGFlashTool, hope this helps you out.

Thanks Cronic2009 for your advice.
There are, however, szenarios where download-mode is not accessible any more. Neither by using the hardware-keys, nor by using the adb-command.
After four days of resarch and a lot of trial and error, I finally unbricked my F320L using the two adb-commands outlined at the beginning of that thread: http://forum.xda-developers.com/showthread.php?t=2451696
Worked like a charm.
Thanks everyone for your advice.

no problem buddy, glad you got it figured out, good luck to you from here on out!
FYI, that link doesn't work
I just wanted to ask anyone who might know, since the bootloader of the LS980 is locked, we cannot "break" this correct, so no matter what commands we decide to run through root, we cant touch the true bootloader there for LS980 fail safe? (Besides Acts of God, EMP, ect)

Thanks for letting me know. I corrected the link in my previous post.

Be sure if you use a aosp based rom to flash the ZV8 modem. Your can use dr87 or furnance kernals after you flash the zva modem althought i have encountered soft brick due to this.

so i'm having this exact issue and i don't know how to get out of it. i just need to transfer the radio to my phone somehow but nothing shows up under adb devices. i'm trying to the lg mobile support tool now. its downloading the software. but if it doesn't work does any one have any fixes?

Hi all
was just about to start a new thread but didn't want to get into trouble..anyway I am in need of some assistance please.my ls980 has been bricked for some time now been searching all over the internet for a solution to be stuck back at square one.found this video on youtube which is pretty much exactly what my phone is doing.I have used lg flash tool to revert to stock and still nothing I lost root doing that but last night,I managed to regain root access I have no idea how but it happened when i clicked ioroot batch file i went into download mode and it stated bottom left ROOTED in red so i managed that but that is it still doing what is being shown in the video its on youtube
watch?v=PjLF-pBhZSY
please if anyone has the know how I would like to fix this phone rather then bin it thank you all happy 4th everyone

After using tot and flash tool to get back to stock, did you try going into stock recovery and do a factory data reset? I know it sounds stupid especially after a tot but try it. Couldn't hurt

Borderline noob here, so please bear with me...
I have been using TWRP 2.7.0.0 to do all my work, and I was able to get the Lego ROM installed with ZVA. I got into too big of a hurry and forgot to make a backup of stock. I've also been unsuccessful in trying to install ZVC modem and firmware. Thankfully ZVA works as does the LEGO ROM, but I'd like to have stock there to access as well. The stockZVC that's on the Android Development page has been getting stuck (bootloop?) on the Sprint Spark logo. I've done TWRP's factory reset with no success. Any help would be great.
Thanks in advance!

Yes sir I've tried that and more to no avail is there anything I can do through adb I'm on stock recovery phone doesn't stay on long enough to install anything

Help! - stuck in "kindlefire" boot screen

Hi!
I have a kindle fire hd 8.9 running the 8.5.1 version.
I managed to root it using the key root master app (i think it was an indonesian/chinese language, which was suggested by one poster), although it was kinda weird because it didn't install the superuser app. Then, i tried to install the 2nd bootloader and twrp using the fireflash app from this thread http://forum.xda-developers.com/showthread.php?t=2277105. But somehow, i couldn't get it to fastboot mode, although it wasn't needed according to that thread. I flashed it using the fireflash app, however, i couldnt get it to go to the TWRP recovery. Then, i noticed that there was an option to go into recovery from the fireflash app, which i pressed, and now, i'm stuck in the bootscreen showing the kindlefire logo. i could turn it on and off, but that's it.
sorry, im quite a relatively newbie at this. from what i've searched, maybe the KFHD srt tools can help with this. Will it work even if i cannot go into fastboot mode?
Thank you. any help would be greatly appreciated!

hopefully you backed up all images first? i made that same mistake with fireflash to "boot into recovery" yep booted mine right into a brick, after several different types of "softbricks" i finally got mine back straight and now kinda scared to try the 2nd bootloader OP again, because idk which bootloader i am on right now and cant find a way to identify it! i will try to find the thread that got me back straight, give me a while

Thanks @Mike. It kinda reassuring to know that somehow you were able to fix your kindle. BUT i have a big problem, i was not able to back up the images (i wasnt able to go into fastboot, i think my windows 8 pc has a problem with that, or is it just me?). is it possible to use your images? (we're both 8.5.1).
Thanks again mike. I think i'll be scared to try the 2nd bootloader again too.

First off you have got to get adb and fastbook working, if not you will probably never get it back useable. have you installed android sdk? if not go here >http://developer.android.com/sdk/index.html#Other< and download the android-sdk windows zip file and install, that should get your drivers going so you can access adb and fastboot. for help installing the sdk manager go here >http://developer.android.com/tools/help/sdk-manager.html< after sdk manager install check your C:/users/yournamehere/ folder and make sure it put a .android folder there (sometimes it don't) and it should be a file in there called android_usb.ini, if that don't get you hooked up to adb and fastboot (assuming you know how to check if adb and fastboot is working correctly) install the Kindle driver package found here >https://www.dropbox.com/s/c0w3po7r65fwltb/Kindle%20Fire%20HD%208.9%20ADB%20drivers.zip< and if STILL you can't get adb and fastboot working i will help you edit that android_usb.ini file(what i ultimately had to do to cure my fastboot woes on this windows 7 box) that i mentioned earlier in this post. once you get adb and fastboot working correctly i will try to help you get your KFHD back up. keep me posted and i will check back as regular as i can! GOOD LUCK!

thats good news! adb and fastboot working now? i hope i helped in some kind of way! you can surely get it back straight now! and btw if you were successful in installing that 8.1.4 bootloader when it messed up, IT DONT GO AWAY! i flashed mine twice with MY factory backup images and still retained the 8.1.4 bootloader from Hashcodes OP. and retained root! anyway im so stubborn and determined to figure things out like this, i decided to try again only after i figured out i still had the 8.1.4 bootloader, and THE ONLY way i could figure out which boot loader i had was to load up fireflash again and see if it give me the RED WARNING in the first line about flashing or not flashing the 8.1.4, sure enough it showed no warning with 8.1.4 bootloader! SO instead of using fireflash i just used fastboot to apply the "stack override script" and flashed the freedom boot 8.4.6 image and the 2.7.0.0 TWRP and went smooth as butter, booted up in TWRP recovery and then rebooted several times to make sure all was good and then last boot in recovery i did a wipe with TWRP and installed CM11 and GAPPS zip and all has been good every since! :laugh: it really is a whole new tablet with CM11! :good: if you need more help i will do my best, trust me i know what it feels like to have the RED SCREEN and stuck in fastboot! keep me posted!

Thanks again @Mike. However, i wasn't able to do my factory backup images. and secondly, what did you use to restore the images? Did you use KKFA or the KFHD SRT? i'm sorry, i kinda scared now to proceed on my own.

From what i've read, you use the KFHD SRT for bricked devices USING a factory cable, is that right? from http://forum.xda-developers.com/showthread.php?t=1951254. Or do i use the KKFirstAide tool from this http://rootjunkysdl.com/?device=Kindle Fire HD 7in ?

no, you DO NOT need a special "factory cable" for the 8.9 inch just the regular cable that come with the KFHD 8.9 or ANY usb/microusb cable like the one that come with your kindle, it's nothing special to that cable. and although i tried using those utilities you mentioned in your previous post to fix mine, NONE of them worked for me! the only thing i used was adb and fastboot commands and a recovery image DOWNLOADED from a thread here, thats was what ultimately booted my kindle back up in "factory" recovery mode (NOT fastboot mode) and it went through a couple prompts (on the kindle screen) and using the vol up/down and power buttons to select and enter respectively to do a factory restore all from the kindle screen once i finally got it to boot into it's own factory recovery. do you have fastboot working? if so i think we can fix it! mite have to go to a IM kinda app or google hangout or something for realtime communication but i feel like it can be fixed!

Thanks a lot @Mike!

I have been reading XDA for years, My KFHD 8.9 recently stopped booting also
My KFHD (Kindle Fire HD ) 8.9" (JEM) recently stopped working one day (about a month or 2 ago) while it was sitting plugged into a wall charger . Mine , since coming back to it while it was charging, stopped running and I can't remember if it was on or off while I charged it, but it's 100% stock and now it only boots as far as the non-animated part of the "Kindle fire" logo screen, and stays there indefinitely until the battery dies , or until I hold down the power button long enough to shut it down. I'm pretty sure it's either bricked (for whatever reason) , or has some part possibly broken on it (internally) ?
--- sidenote: one time I was given a case for a tablet, and without thinking about it, tried to see if my 8.9 inch model fit inside it and it didn't. Without forcing it in, as far as it did get in, caused my KFHD to reboot on its own?!
my only question here is , Is this a similar enough case , or is there anything else I should do to fix this? my device beeps on multiple computers I've attached it to , notifying it was detected by windows, and about 1/4 second later it dings the disconnected sound and I've never managed to get KFHD SRT (of any version) to work for me at all. Fastboot does not detect my device, even after installing drivers (have attempted this on a windows 7 64 bit computer, and a windows 8 64 bit computer, neither have shown any sign of functionality with fastboot)

I dont think this is the same case @Umisguy as you have not tinkered with your tablet (100% stock), while mine happened while trying to install a custom ROM. Maybe the amazon guys can help you?

Do you have 8.5.1 or 8.4.6 system image and the boot and recovery files

Folks,
I got in to the same trouble able to mess up the KF and get a redscreen but used KFHD SRT to reflash the 8.1.4 system image, boot image, recovery image but now I ended up in the boot loop mode where it shows reboot kindle or Reset to factory Dafaults but as I flashed every thing am unable to reset to factory. As I got the tablet recently it came with 8.5.1 so I need to try with the latest image I can get.
If there are any suggestions i can try please let me know.

Which stage of bricked are you at? I don't exactly understand how far you got or didn't get? Red screen? Orange kindle screen? Boot loop? If you can give a little more detail I may be able to help

I was on 8.5.1 when i did mine, BUT the boot image you will be using is the freedom BOOT image is 8.4.6 from Hashcodes thread and the "2nd" BOOTLOADER is 8.1.4 also from Hashcodes thread.....I also have "my" STOCK BOOT IMAGE from 8.5.1 from my backup i did BEFORE i started this OP
Hope this helps and not confuses you more!

I am at the boot loop where it shows the kindle reboot or factory restore option and it loops into that screen forever. Before that I hit with a redscreen and able to get the device into this loop mode by using the 8.1.4 system image, boot , recovery images. Now I ended up in this boot loop so I wonder If I have the actual 8.5.1 system,boot,recovery images I can flash them in the fastboot mode on the device. Also another issue am facing is ADB command cannot recognize the device even though am in the fastboot mode.
Thanks for the prompt reply mike.

I'm at work so kinda limited to my replies and quickness, and I'm by no means a dev or pro at this, I just learn by trial and error and lots of reading, especially when it comes to the kfhd! I went through this same mess SEVERAL times with my kindle before I finally got it straight! Bricked mine several times, once to the point I thought it was toast! So I no how you feel! 1st thing u need to know is adb only works when device is booted up in the os, that's why you getting device not found, but fastboot will work as you know, if you successfully flashed the 8.1.4 boot loader then its there to stay at least in my findings, after flashing back all my stock images and multiple factory resets I still had the second 8.1.4 bootloader installed. I'm using tablet now at work and I have the thread bookmarked on my PC at home that ultimately got me back up and going but I will try to find it and get you a link, if not I will post the link when I get home after work around 5 30 est, there is a recovery image that you will need to flash that should get you back into factory recovery mode and work instead of looping

I am at the boot loop where it shows the kindle reboot or factory restore option and it loops into that screen forever. Before that I hit with a redscreen and able to get the device into this loop mode by using the 8.1.4 system image, boot , recovery images. Now I ended up in this boot loop so I wonder If I have the actual 8.5.1 system,boot,recovery images I can flash them in the fastboot mode on the device. Also another issue am facing is ADB command cannot recognize the device even though am in the fastboot mode.

hopefully you backed up all images first? i made that same mistake with fireflash to "boot into recovery" yep booted mine right into a brick, after several different types of "softbricks" i finally got mine back straight and now kinda scared to try the 2nd bootloader OP again, because idk which bootloader i am on right now and cant find a way to identify it! i will try to find the thread that got me back straight, give me a while

Thanks @Mike. It kinda reassuring to know that somehow you were able to fix your kindle. BUT i have a big problem, i was not able to back up the images (i wasnt able to go into fastboot, i think my windows 8 pc has a problem with that, or is it just me?). is it possible to use your images? (we're both 8.5.1).
Thanks again mike. I think i'll be scared to try the 2nd bootloader again too.

ok @krishnasanga go here http://forum.xda-developers.com/showpost.php?p=37278819&postcount=193 and grab the boot image from step 3 and the recovery image from step 4 and place those in C:/ or wherever you have your adb and fastboot tools, should be in C:/ to make things easier but don't HAVE to be if you know how to enter correct paths in the command prompt. IGNORE all the Kindle First Aide stuff, you will just flash these with regular command prompt running as ADMIN (right click command prompt,click run as admin) start at step # 6 (ignore first aide stuff) and open command prompt running as admin and go from there EXACTLY as it says with kindle plugged up to usb and powered OFF. most likely HOPEFULLY you will not have to go past the reboot in step 8 and you will be in factory recovery and will be able to "reset to factory settings" assuming the recovery file is flashed successfully, if you do get to step 8 without issue and get to the fastboot erase userdata -i 0x1949 command, don't panic if it seems like it's taking a long time, i have seen this userdata erase take up to 40+ minutes! IF you get that far and userdata gets erased properly the next command to reboot "should" put the kindle into factory recovery where you can "reset to factory" and will not keep looping. GOOD LUCK! hope this helps and works out for you and i will be around the rest of the evening if i can help let me know and i will try

Mike,
I tried with this new boot and recovery images but still stuck in the loop , can you upload your backup files of 8.5.1 system.img,boot.img,recovery.img I think that will be my last shot to try to unbrick this device.
Thanks,

[Q] Need help fixing my Gnex

Hi,
it is the second time my Gnex went into endless reboot loop sessions.
It will boot, load crash after few seconds and reboot again.
I had it unlocked in the store i bought it, and had stock rom (Not sure about the version).
Tried to do factory reset from fastboot, from recovery, and from android. Also tried to flash custom boot loader, Nothing works.
Although fastboot writes it successfuly completed the action so does the factory reset. The phone will work for few seconds but no more.
Also tried using WugFresh, for factory reset and for Flash Stock + unroot in soft-break status
I have no ideas what to do next,
Please help.
Mike

Hi Mike, I think more information is required.
- What action did you take immediately prior to having your phone get stuck in the bootloop? Were you trying to install a Custom Recovery or ROM?
- You mention that this is the second time this has happened. Do you know what caused it to bootloop the first time, and if yes what fixed it?
- When your Gnex is in Fastboot/Bootloader mode, and using a tool like Minimal ADB and Fastboot on your computer, does the tool recognize the Device ID after using the fastboot devices command?
You may also want to read through this thread.

Hi thanks for the reply, i am a simple user, prior to the bootloop i was using whatsapp, actually the android crashes few seconds after getting a whatsaap message (i recieve notification and it goes down). Previous time also i didn't do anything special. i never installed custom recovery or roms... previous time it was fixed by a lab the phone was on warranty.
And yes the tool recognize the device.

So your device receives a WhatsApp message/notification, restarts, and then gets stuck in a bootloop?
That is very strange, as personally I've only ever encountered bootloops after bad ROM flashes (usually after I accidentally skipped a step somewhere during the process). Bootloops usually don't happen to regular users who are just using their phone purchased as-is from a store/carrier.
If you can get it to boot back into Android, try uninstalling WhatsApp and see if that helps. Hopefully it's still under warranty, as you may have to take it back to the store and have them look at it.

Tried to uninstall whatsapp but it crashes before i manage to do so.
even managed to access memory via TWRP and delete whatsaap manually but somehow it appears again after restart.
Something is terribly wrong

Let's see then. Be prepared to spend at least 30min reading, and re-reading, until you actually feel comfortable in what you're doing/typing in. If you're not sure about the technical terms and what lies behind them, read this thread's #1 First Post.
What's your device variant? maguro? toro? toroplus? This will tell which factory image you need to flash.
You need to flash latest factory image, which is (for maguro variant) Android Build 4.3 (JWR66Y). Read #1 First Post on this thread. And I mean, READ IT! Do not do anything else to your device until you do.
After you flash the factory image, that first boot will take a while to reach Android. Chill out. Go get yourself a drink. Take your time. It should have booted into Android already when you get back. It should be fine, but if not, you need to enable USB debugging under Settings > Developer Options, to check the system log.
If after 15min, it still has booted yet, pull the battery out, wait a few secs, put it back in.
Use the 3bc (3-button combo) to reach fastboot mode again. Flash a custom recovery. That's done by downloading the latest TWRP or CWM (i'll leave that choice up to you, be mindful that you might wanna try them both in the future), and running on the host (the PC):
Code:
fastboot flash recovery recovery_filename_here.img
Don't reboot the device. Use the volume keys to "Reboot to recovery" straight from fastboot. After a few seconds, you should be seeing the custom recovery you've flashed with the fastboot command above.
Now comes the part where ADB is required. I hope you've already read the answers to questions "Where do I get the driver for my PC?" and "Why do I need to install the driver twice?". If not, read them now. Also, read "What is ADB?". TIP: When a custom recovery is actually running on the device, ADB mode is already active by default, so when hooking up to the pc the device will show as an ADB interface, so installing the driver (if needed/not done yet) is piece of cake.
After you get ADB to recognize your device (like, you see your device's SN on the output of command `adb devices`).. You need to copy a custom ROM to your device, and flash it. That will get you, most likely than not, Android's USB debugging by default (read answer to "What is an insecure boot image?" on the first link), and that will allow you to see the system log, WHILE Android is booting up. Why do we wanna do this? Cos we want to see if any errors show up, something that may tell us what's failing.
When choosing a ROM from the Android Development section, ask around in the thread if the ROM has USB debugging enabled by default.
Read "What are the ADB commands?" in the thread I first linked to. You'll need to learn at least `adb push` for now.
Once you get the ROM in your /sdcard/ or whatever folder you like, disconnect the USB cable, wipe data/factory reset, then install zip from sdcard (that zip you pushed before).. Forget about gapps for now.
Connect the usb cable, reboot, and once you see padlock screen go away, start trying to run `adb devices`. Do you see your SN in the output? Once you see it, good, it already connected to adb on the device. Run `adb logcat` and try to look out for errors. Logcat is the system log.
To know how to grab that output to a text file so that you can share it with us.. Google it, my fingers hurt.

Thanks beekay201,
As a matter a fact. shortly before you posted this answer i gave up and gave my phone to a local lab.
But unfortunately they were useless and didn't manage to do anything claiming they don't have spares for my phone, tried to explain that it is not a hardware issue, but all in vain .
Anyway, ill go over your instructions and ill update the results soon.

Unbrick a FireTV

So, I've been trying to fix my Netflix playback issue. I uninstalled Netflix before I started this process.
My FireTV was running 51.1.6.0 rooted, the boot loader was unlocked, I had the boot menu installed, etc.
From what I'd read, it looked like I may have installed a pre-rooted version some time back that had an issue with Netflix, that was corrected in the "updated" version of that release. I didn't have Netflix at the time, so I didn't know I had a problem. So, I loaded the 51.1.4.0 rooted+updated and 51.1.6.1-rooted onto my FIreTV /sdcard/ directory, ran the md5sum to make sure the files were transferred right, then loaded 51.1.4.0 via recovery. After it rebooted, things weren't quite right. I couldn't install the Netflix app (when I selected the icon, I think the screen flashed and it was back to the same screen). PlutoTV would load, but Mediaah complained. On the Apps section, it said something to the effect of "Your apps will show up here soon". I could still launch Kodi and it seemed to work fine.
Anyhow, I entered recovery mode via ADB and installed the 51.1.6.1. Now my FireTV is sitting at the animated FireTV screen. It no longer gives me the boot menu as it boots up.
What did I do wrong? Did I need to do some more steps while running 51.1.4.0 before loading 51.1.6.1? Did I need to install another version between 51.1.4.0 and 51.1.6.1?
So far, I've not been able to make any headway recovering. I can't connect to it via ADB to enter recovery mode. I don't have a USB PC keyboard to try the ALT-I-PrintScreen trick on boot. I've just ordered a USB A to USB A cable to try the fast boot recovery, but if loading 51.1.4.0 has broken by bootloader unlock, then that probably won't work either.

Installing 51.1.4.0 wipes out the boot menu. Since 51.1.6.1 requires the boot menu, you soft-bricked when you installed 51.1.6.1 without having a funcitoning boot menu.
The good news is it's a simple fix. You should be able to get into recovery using the ALT+i+PrintScreen if you can get a hold of a USB keyboard. The A-to-A USB cable will also get you back to working order if you prefer to go that route.
Just follow the instructions carefully here: http://www.aftvnews.com/how-to-unbrick-and-prevent-bricking-an-amazon-fire-tv/
EDIT: I've added a warning to my ROM page, next to the 51.1.4.0 download, to help people avoid what you unknowingly did. If you used my ROM page, sorry the warning wasn't there earlier. Please feel free to PM or email me if you need any additional help recovering.

Thank you for the explanation. I thought it was something like that.
Is there any specific time during the boot process that I should be trying to hit ALT-i-Print Screen?

There isn't really any indicator. Just continue to press it repeatedly through the whole boot process. I don't mean hold it down the whole time, but rather, press, release, then repeat. If you can't get it to work, just follow the steps under the "Repair Recovery with Fastboot Mode" section of my guide. With that, there's no guess work, and you'll get into recovery immediately.

Got it with the USB keyboard!
But only after I read this link (http://www.aftvnews.com/how-to-unbr...ry-mode-and-factory-reset-the-amazon-fire-tv/)...
Before reading that page, I assumed I just had to hit it at the right point in the boot process, like entering a computers BIOS or something. But that page explained what the system did when you hit ALT-i-PrintScreen, so I knew not to give up.
I have a USB A-to-A cable that will be here tomorrow that I don't need now, but it was cheap insurance.
Thanks again! Your web site is a very valuable resource! Not to take anything away from all the hard work of the guys who frequent these forums, but having everything curated in one place, with instructions for mere-mortals is great.

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.

Please read carefully before you try and flash something - both methods requires USB-Download-Mode, which is actually in my case NOT possible anymore.

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

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?)
THX a lot

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!!
