[Q] Sprint lg g2 boot certification verify - Sprint LG G2

Hello. I've spent about the past 2 hours trying to figure this out. So, how this started was, a while back when I first got the phone, I wanted 4.4, so I rooted my phone, and tried to flashify a recovery like CWM and TWRP. Both of these failed. I tried many times, and no matter what I tried, flashing always failed. But guess what, my stock recovery was erased in the process. I forgot about it until today, where I found the OTA update to 4.4 was released, and attempted to do it. To my dismay, I forgot I had no recovery mode, and instantly got the "boot certification verify" error screen. Now All I can access is download mode, to my knowledge. So I've been trying to fix this, either by installing stock recovery, or another way to install a custom. All to no avail. When I use the lg flash tool for the stock recovery, it fails at "BIN CRC Check". Every.... Single.... Time. Despite downloading multiple replacement files. I would be perfectly content with installing a customer recovery, but the ways I see require the phone to be on, and use the built in recovery mode. At this point, my phone is bricked, and I am looking for any and all ways to either A) boot back up normally without installing a recovery and fix it later, or B) install a recovery, even if it's the hard way.
Update:
I followed this thread:
http://forum.xda-developers.com/show....php?t=2582142
It looked like it was going to work. I am using a Xubuntu virtual machine. I was copying the files over, and every time it finished copying a file, it unmounted and remounted my phone (I don't know if that was suppose to happen, just worth mentioning if it wasn't suppose to). I was super excited to do it. Hard rebooted my phone. And now it's just a blank screen. I have no logo, no error, and no download mode like I had before. Seriously need some help here.
Update#2:
I have the flash tool correctly working. Awesome! But..... I still have no download mode here.... So I can't use the tool....

I'm decently surprised NO ONE has replied here.

is this **** bricked??

its just sitting on the freaking LG screen... every time i vol dwn + pwr and double press power it goes normal but then cwm doesn't come up and it just restarts and hangs at LG again. i ****ing hate this phone can someone please help me out? why won't cwm load
can you describe exactly the process you took to port CWM into your phone? Let's see if something happened along the way to cause it to not work properly.
Also, is CWM the one not working, or did you flash a ROM on your phone and something went wrong, and you are trying to get to CWM to restore your phone but not getting anywhere with it?

followed the steps on the cwm thread. used terminal emulator. worked great. was working fine until now. i flashed kernels beta 2 and only wiped cache and dalvik and now nothing is working. no cwm to restore, can't even get to the at&t boot animation. this is a mystery.

Sorry to hear that. Unfortunately I can't help much at all since I haven't done either yet (CWM or Kernels/rom installations) so rather than making things worse for you, I'll leave it to the Pros here to help you. Im sure one of them will respond back soon enough.
Try this:
Disconnect the phone and pull out the battery.
Put battery back in and plug phone to a wall charger. Let it boot to the battery charging screen. Once there press and hold POWER + VOLDOWN
Depends on type of the problem, it helped me 9 out 10 times...
tried it at least 20 times now. just realized that i didn't format /system nor did i update cwm yesterday. probably the root of all these problems. I'm just gonna start fresh with the kdz. I'm on a mac though so its going to be a long night starting with boot camp.
I'm having the same problems...well kind of...
I followed all the instructions for CWM and everything went great. No real issues but had to reinstall the .img twice and then was perfect thereafter. Saw the beta 2 ROM and figured what the hey...downloaded and installed to SD Card. Used CWM/Nandroid to do a backup then installed the zip for the ROM from the sd card.
It took a matter of 10 seconds and said it was successful/done and restarted phone-got a boot loop on LG screen for about 15 minutes and finally did a battery pull-tried several times to get it into CWM with no luck and finally was able to get in-but had to plug it into the wall and wait for charging screen to show. Was able to restore and all was well until turning the phone off.
Turning off the phone now causes the phone to loop on the ATT screen-I can get into download mode and can get into CWM and restore and all is well until turning phone off.
I figured it just needs a fresh install so I've been trying to flash the kdz but the firmware updater keeps faulting and never makes it through the process...so I'm stuck...have all the files I need (I believe) and have everything in place...just can't get it back to normal.
Any ideas from here?
Thanks in advance!
Yeah, sometimes it could be quicker just start over and restore backups...
While you there, would you mind do this: Needed SystemUI.apk from SU640
[EDIT]
@fishscale28:
did you do kdz unbrick before? If not, then perhaps you are not doing it right...btw, kdz file for LU6200 didn't work for me.
Nope-never done a kdz unbrick before-I have the kdz v10i_00 for the 640. I have all the drivers installed, the parser deal installed, windows enabler program running and use the kdz updater to update the firmware. Is there something Im missing here? Seems like several people have gotten the updater to crash when trying to update the firmware...any ideas why?
---------- Post added at 05:51 AM ---------- Previous post was at 05:38 AM ----------
I went through a few of the threads and saw there was a .dll file to be deleted in the updater folders so I did that and now I can do absolutely nothing with the program. Only start and exit...am unable to select anything, view anything, get anything to function...

I installed from the kdz yesterday and didn't have to delete any files. I'm on Win 7 x64. The first time it ran it told me to restart my phone cause it didn't see it, but the second time it ran until my phone reboot and I killed the program. Be sure you have the KDZ_FW_UPD_EN with UpTestEX_mod2_marwin.exe in it. Hope this helps.
Thanks for your help. I did all that...again...I even deleted, reinstalled all the updater stuff, tried running as admin, tried running in compatibility mode, ran it after deleting the recommended .dll file and the option to do anything was gone, put it back in and was able to run everything fine and a little after extracting the kdz it would crash. I unplugged the phone and re-ran the proggy and it went through the check, noticed the phone wasn't hooked up and finished the check. Plug phone in, start process over and proggy crashes.
I don't get it-I would say its the wrong kdz but its not. I installed all the drivers and it still doesn't work. I've tried every combo of everything and the proggies keep crashing.
Now I was finally able to get into CWM to flash another ROM and was able to get one going-was able to boot into the os but same as before-once the phone is turned off it starts the boot loop. Now its even harder to get back to CWM but a restore works from there. Any ideas on why the boot image keeps reverting back to whatever was screwed up? Has to be something that happens once the system starts up again as it's after a restore and when the phone is turned off. Stumped and would love to be able to use my phone...It seems like flashing the kdz would be the sure fire way to get it done-are there options aside from the updaters that keep crashing?
Thanks in advance!
Maybe http://www.microsoft.com/windows/virtual-pc/ can help?
alright so i got to the 4% thing and my phone rebooted but it kept looping to the screen LG Optimus LTE bootscreen with the pink candy cane. thats it. i did vol dwn + pwr and got the android arrow and box with loading bar no text, then it rebooted back to the optimus lte screen. never got to the setup screen. tried the kdz again and my phone died. now when i plug it in i only get download mode... does it charge in download mode and why did it not get to the setup screen?!

Even after running the kdz, my phone still does that after installing CWM. I don't know if it's something with my ROM or something with CWM, but if you can't get into CWM you probably don't need to run the kdz. I couldn't get into CWM anymore when I ran it.
So you're saying you go into the boot loop after turning off your phone even after unbricking?
I don't get it-now I can't get into recovery and it keeps up with the boot loop. I've tried running on the virtual PC/XP deal and it doesn't crash but now it doesn't even see the phone...reinstalled all the drivers, etc. and still no luck. Is there anyway to get the kdz installed without this updater?

Yes. I don't think that was happening until I put CWM on. But I can live with it until the issue is solved. I don't think I'm the only one having it.

Can you enter recovery?

Ouch bud you are hard bricked pretty much. It sounds to me from what you explained all the partitions are wiped clean. I don't think there is any recovery from that unless you have a nand programmer

Im confused you said you had download mode then didnt? If it works try using the alternate G2 dll named 8974, because the second time I used Flashtool only the alternate dll worked which is weird because just hours earlier I had used the original, the original said wrong model/download failed the second time.

As I explained in my update, the method I used didn't work and had removed all modes I could boot into, including download mode.

Then use LG Flash Tool, the Verizon guide works for LS980. Except use LS980 dll, and you must use Verizon USB drivers (Not T-Mobile, ATT etc), or Flash Tool wont work.

I definitely hope you only semi bricked..... Tell me if that works.

[HELP] I think I screwed up, factory image/bootloader help

EDIT: SOLVED. After some hours at work I was able to boot back to the bootloader and flash the images individually.
TL;DR at the bottom.
Hi, I've been rooting and ROMming for a while now, and last night I made a mistake that set forth a chain of depressing events. I have a N7 2013 LTE, and was running AOKP up until last night. I wanted to flash the 9001 L preview, despite having no access to data. Simple right? Wrong, you forget to realize I'm a tired idiot last night. I downloaded the zip no problem, rebooted to TWRP and commenced my advanced wipe. Some how, I mistakenly checked off "wipe internal storage" during the process. So I go back to the Install screen, and my heart sinks. F***. At this point I decide to let it lie in recovery until tomorrow (today) and keep it charged.
Fast forward to this morning, I'm at the office. My device is charged and waiting in recovery. I decide I'm just going to flash the factory image to stock 4.4 and start with a clean slate, wiping all (even though it's wiped). Reason for factory image and not just adb push the ROM is that I'm having a seemingly-unsolvable issue of incorrect storage. It tells me my 32gb device only has 11.6 gb total storage. This has persisted through multiple clean-wiped installs of various ROMs, but I don't know if it started out like that when I bought it, since I didn't think to check before unlocking and putting a ROM on it.
So I get the SDK and images on my work PC, and commence flash-all.bat. Working great until it gets to system.img, then it fails. Try again twice, same thing. Open the image zip and extract the files, then try to flash one by one, now it's saying the commands are invalid (fastboot flash system system.img, etc). So I wonder, because sometimes these devices are wonky in ADB, maybe it installed and just said it failed? F*** it, I'll try to boot. Google logo for an hour. Ok, cool, I'll go back to the bootloader. NOPE. The device either won't power on at all, or it will get stuck at the splash screen and hang there. Any idea where to begin to fix this?
TL;DR: No OS on phone, failed flashing system.img in flash-all.bat, now device won't boot to bootloader or (missing) OS. Any ideas?

[UNBRICK] Getting into recovery/unbricking V410

I'm posting this just because it might be helpful for others, as well as providing some warning for anyone else who might one day get into the same situation.
I was rooted and had installed TWRP on my new Gpad 7.0 V410 and everything was running just fine. I've been modding Android devices for years and thought I knew what I was doing. I didn't like the AT&T boot animation and thought I'd replace it. I found the stock animation in system/media, and replaced it (with a Nexus 7 ani) just like I'd done on previous devices.
When I rebooted, the animation started and ran. But then it hung, and rebooted. It was now stuck in a bootloop. Well, no problem, I thought, I'll just get back into recovery and restore the stock ani.
That was when I discovered how locked down the firmware is on this device. No fastboot. No standard Android bootloader. Not even, as far as I could tell, anyway of rebooting into recovery using the hardware buttons.
I could get to the factory reset screen and download mode, but neither have any way to get to recovery. ADB could not connect. The LG support tool found it, but did nothing but tell me the firmware was up to date. Lots of searching and reading turned up similar tales of woe. I began to worry that there was no way out.
Having no other ideas, I tried doing a factory reset. It ran, and lo and behold, kicked me into TWRP. From here, I confirmed that the device was wiped.
However! I had had the foresight to create a TWRP backup on my external sdcard, and that was still there. Restoring it got everything back in working order.
The moral: If you're up and running now, make an external backup. It could save your butt just as it did mine.
Amen
I'd just like to add that you can enable fastboot on this tablet for anyone who might read this thread. If you follow the method described here you'll lose download mode, but the tablet will fall back to fastboot when download mode fails. :good:
Without a kdz file released for the V410 the download mode isn't really good for anything, but fastboot gives you a fighting chance of being able to flash your way out of trouble if you brick your V410. Probably advisable to keep a backup of the laf partition just in case you need it someday.
Aha, thanks, I had seen that referenced several times, but wasn't sure where to go with it, and wanted to try less extreme methods before attempting something like that.
I've been spoiled by modding HTC and Nexus devices up to now, so this is a bit of a culture shock over here.
Edit: Decided to bite the bullet in case of future problems and nuked laf. Ah, sweet fastboot. :highfive:

[SOLVED!] Problem getting ANYTHING onto the E980

Well, as usual, I've managed to mess things up and here I am again. Somehow, I installed something or other that required rebooting. When I did, I kept getting an error that the systemui was messed up. So I decided to try to flash a custom ROM since it appeared this thing was already FUBAR and that's where the fun began. It WAS running stock 4.4.2. I wiped everything in preparation to flash the stock .tot file. Went to flash a zip from the external sdcard, and it refused telling me it couldn't mount the card! The only hopeful thing is that it powers up, I can get into download/recovery, and it's recognized by the PC through LGFT and ADB.
I can't flash anything, can't push or install through ADB, can't sideload anything. LG flash tools gets to about 38 seconds and then fails. It's like the devices permission were all changed to read only. The device is rooted and has CWM recovery. Is there a way to completely slick this thing (except for recovery - I'd do that too if need be) to reset permissions.
Any/all suggestions gladly accepted.

Surprisingly, there was nothing wrong with the phone nor the software nor the PC. After screwing around with this for a couple of days, I had a thought to try a different USB cable. So, I popped it on and, lo & behold, I'm able to flash to stock! Lesson learned: Don't use cheap cables and try changing cables when you're have weird problems like this. :good:
