[Q] Softbrick help requested - fixes not working - LG Optimus G Pro

[FIXED]
After installing CWM via FreeGee on my G Pro F240L, the device became softbricked (booting only into CWM). I tried various methods to unbrick. including the R&DTool flashing method, but encountered various errors, including the infamous battery error. When I looked at the device this morning, however, it had rebooted itself overnight and was now stuck on the LG boot logo, with the following small text in the top left corner:
Secure booting Error!
Cause: boot certification verify
The device no longer appears to be recognized in adb from my PC, and though it is still capable of booting into download mode I have had no luck with the methods posted by others for bypassing the battery-level error in the Support Tool/flasher. If anyone could help, that would be immensely appreciated.

Can you still get into recovery? And when in recovery does adb then detect the device?

No, I can't enter recovery, the only method of modifying firmware available to me seems to be Download Mode.

So you have tried flashing back to stock using the flash tools? It's not ideal but it get the phone back up and running. I own a e980 so im not familiar with the battery error you speak of.

Yep, tried several variations of the flashtool method. The battery error: at about 50% through the flashing process, it throws an error essentially saying the phone's battery needs to be at 100% in order to continue, problem being that the error comes up even when the battery is at 100% - and also comes up if I try with the battery removed from the phone.

Has anyone experienced a similar issue? I'm getting quite desperate.

Man if you could just get adb enabled.

That would certainly make things easier, but it seems impossible to do seeing as the phone either can't boot past the logo, or only into Download Mode.

Add my e980 to the list =/ just hit this problem as well. I have it worse though since I don't have a windows PC. Can't even get into recovery. All I get is the Boot up screen with the same message you received.

hello
i have f240l i returned back to stock backup which i made CWM i received an OTA i accepted the phone restarted and after that its stuck in recovery mode only. what can i do to make this work again

I also used Freegee and it messed up my device. I don't think this tool works correctly for the OGP (e980).
Can anyone tell me if I can get back to the AT&T stock ROM using TWRP ? If so, how?

[Q] Unable to get into Bootloader [Bootloop]

So I bought myself a Galaxy Nexus from Ebay and it arrived today.
The problem with it is, that the seller told me he did an OTA Update that in the end causes endless Bootloops.
I thought to myself that this should be easy to solve by just flashing a custom rom but I don't even get to the Bootloader.
Whenever I press Volume Up + Down + Power the Google logo appears without vibrating or anything.
Then it goes on to the Nexus Bootscreen till it just restarts.
Any Ideas?
Does adb recognizes your de vice?
Sent from my Galaxy Nexus using xda app-developers app
Isn't it necessary to be able to boot to check that?
So it looks like my phone is soft bricked.
There's still the problem that I'm unable to get into the bootloader aswell as into download mode.
I also already tried the OMAP flash tool.

It will get you into Odin mode similar to pressing Vol down + Power, then you can use Odin to flash a new firmware which is very dangerous and could brick your device if done wrong

[Q] Bricked GNex?

I was doing a lot websurfing and the phone got hot but didn't think much of it. Then my screen imagine became distorted and a loud noise came out of the speaker. I had never seen it before. I figured the phone crashed. The power button didn't work, so I removed the battery and put it back in. Now the phone can't get past the "Google" screen (which blurs after a few moments). My phone is unlocked and rooted. It's been so long since I've flashed my phone that I don't know if the usb debugging is turned on and here's where my problem lays. I can't get the phone to be recognized by any of my computers. I've tried a bunch of tools, installing different drivers, and Odin. All of them can't see my phone. I can boot into Fastboot and Odin. I can sometimes boot into CWM, and if I do, all I see is "ClockworkMod recovery v5.8.0.2" and no other options. After 15 seconds, the phone will exit CWM and reboot.
Anyone have any ideas on how to fix this?
Can you boot into recovery and maybe full wipe and re flash? Have you tried a backup? Have you tried mounting in recovery? Should be SD or USB mount try that maybe. I'm not a Dev. But I would try all those first. Post back if possible.

Since you can boot into fastboot, then follow this if you want to return to stock immediately and start fresh, or keep this method for later if you want to try some other solutions first. It is your choice

I think it is bettER to uninstall the drivers you have already, and try another USB port. Did you try that as well?
Download the galaxy Nexus toolkit and that will apply the stock image vai google. You can restore your phone from scratch back to stock.

Okay, I figured out why my computer couldn't see the phone. The USB cable was bad. It charged the phone, so I assumed it worked. Tried another cable and now the computer sees the device. Stupid cable!
So, I got going using fastboot but now I have another problem. I can connect to the phone and my computer sees it, but when I try a flash command like "fastboot flash bootloader bootloader.img", I get "Failed (status read failed (Too many links))". I've been doing some reading and see this is not a good thing.
I haven't tried Odin, because I read in another post by efrant, not to use Odin if I'm getting the "Failed (status..."
I probably have a hardware issue, right? Any suggestions?
Thanks to everyone for their input!!!
I tried using fastboot to boot into the latest recovery .img file. Again, all I got was the title "ClockworkMod Recovery Mod 6.0.1.9"

Try using fastboot to flash TWRP recovery image not CWM.
Download it from here if you have GSM GNex (Maguro), otherwise, just choose your device from the same website
And what about returning to stock using fastboot? You changed the USB cable so seems this should work with you now.

I just tried TWRP recovery and got "Failed (status read failed (Too many links))".
I also tried using fastboot to return to Android stock rom. That didn't work either.
I think I'm screwed. Man, I didn't even overclock the cpu. :crying:

Well, I searched for that error and found this thread. I checked it quickly and there are many suggestions up there to solve the issue like changing the cable, ports, and so on. So please take some time to read through it and try the various solutions so hopefully this error will be solved
I too have had issues with cables. Never that same error but I've had read and write errors. I've resorted to using a 3yr old Motorola Droid power cable because it seems to be built the best. I've also had success using different ports and computers.
Also instead of updating the drivers to the newest try deleting the device out if device manager and rebooting and then installing the device new. That has fixed a "hardware component ID" error I had

Gnex constant reboot

Today my Gnex randomly rebooted, then got stuck rebooting. it now starts gets all the way to the home screen then reboots, then the cycle starts over. I am rooted runny shiney rom. nothing new installed recently and as stated before the phone was running normal the rebooted out of the the blue.
I have cleared cache, davik and done factory wipe, all to no avail.
the text on bottom of my bootloader reads:
Product name-tuna
variant- toro 32gb
hw version-10
bootloader version primemd04
baseband version-i515.fk02 cdma-unknown
carrier info-none
i cant flash the factory image because the phone doesn't stay powered on long enough to stay connected to the computer. apparently when i re flashed and root i forgot to make a back up so i can not restore that way either.
You could try pulling battery put back in and hold volume buttons and power to get into fastboot mode and flash factory image. Maybe you already tried this but maybe not so thought I'd throw my thoughts your way.

Debugging mode is only important when you are trying to use adb while booted into Android. In the bootloader, debugging being on or off doesn't matter. It also doesn't matter in recovery either.
Something is wrong somewhere, drivers are usually the best place to start as it is probably the most common reason why the device doesn't communicate with fastboot. Other things to try are different USB cables and USB ports.

Well looks like you know what your doing so looks like you have a major issue beyond my skill level. Sorry i couldn't help. Never tried it but Odin may be a thought. If you can get into recovery you could side load using adb also.

Have you tried the flash-all it seems to do some formatting that may help but I think it does that later after the radios. Warning it will wipe your phone including sdcard.

Have you tried connecting it into download mode, and then flash an odin image through odin? with that method you wont need to actually put the image onto the device but rather odin just copies it over for you while flashing the phone at the same time.
Same issue
My phone started randomly rebooting, and wont stop, it can't get past the lock screen without crashing on me. However i went into recovery, wiped everything, and flashed back to the stock rom ( i was running the shiny 4.3 rom) and the issue is still persistng, anyone know what can be done, or is something possibly wrong with the hardware?

Workaround:
Make use of your installed/reinstalled recovery system to restore a rom or better nandroid-backup that is already as close as possible to your stock firmware. From there the kdz flasher should work (at least according to my own experience).
This backup worked for me(E986)

I had 2 times problems with low battery issue. I passed it only changing from Diag mode to emergency.
And also it seems to me that the kdz flashing procedure passes only randomly without battery issue. But only on emergency.
I also reinstalled all drivers to reactivate usb ports. With some patience it should pass through

[Q] Stuck at bootloader

Hi!
A few days ago I flashed Gohma rom and smart me, pressed reset device at the settings. after that there was bootloop. I tried to flash stock image through fastboot, it flashed succesfully but now I cannot get out of that bootloader screen. I have tried every stock images but no luck... Whenever I power on the device it vibrates three times immediately and boots to bootloader.
So, do you have any advice here?
In the gohma ROM zip, there's a return to stock script. Try to remove the two adb commands from that script and run it to flash your watch.
It's helped some other people.
