[Q] HARD Bricked LG G FLEx?

[Q] HARD Bricked LG G FLEx? - LG G Flex

hello i would like to know if someone knows how to unbrick the lg g flex ls-995
i can enter to download mode and i know how to flash again the .tot file but unfortunately when i plug the device my pc won't detect and i can't set the device to port com 41.
adb commands don't work and when i power up normally the device it will boot but will restart in less than 2 seconds.
any idea??

Drivers issue?
Clean your usb port...

did you do the master reset by pressing volume+ & power key
hold both the keys when you see the lg logo release the power key and press it again immediately.
try it...
and yes also reinstall all the lg drivers
hope this helps

achieve APX mode and other tricks adhoc

Since this model is new, i assume all facts are new too.
- SAFE mode is started by holding Vol+ and power button at the same time at startup.(adb shell is enabled, nothing is running(single user mode?)
- FIRMWARE upgrade mode seems to be Vol- with USB cable connected at power-on.
- APX mode is started by holding Vol+ and Vol- down at the same time at power up(when pressing power).
* since we do not have a bootloader.bin yet, it will be hard to try anything. can we use htc onex bootloader.bin?
* tegra3 is also locked with a SBK, which we do not have either (i believe).
-Battery mode
Turn off mobile. attach USB cable to pc and mobile. turn on mobile.
- adb reports shell not found and some root details?
im still digging into the fastboot mode, so information can be extracted on the rom rel. etc.. maybe someone already knows?
ill keep this updated, if i find out more.

APX drivers
Do you have APX drivers for 4X ?

not yet, i assume those for asus prime should work as well?

it not work.

@Dexter_nlb
I read that Asus will release NVFlash for Asus Prime.
Do you think it will also work for us?

I believe they for a fully working apx mode since prime got a full recovery using apx mode?

recovery details added.
thanks to 911rsr

Nothing happens. Nothing shows on screen. When i hook it to computer, it makes a noise that it found some device, and in device manager shows as APX, instead of as modem or anything else....

Bricked. APX mode only
Did you find how to fix it?. I have the same issue after a failed upgrade using LG mobile support tool.
No SW upgrade mode, no screen or leds activity, no nothing. When is connected to PC, APX device is recognized. I found some drivers and the APX device is displayed now as "NVIDIA USB Boot-recovery driver for mobile devices". I'm stuck there. I was looking into NVflash utility but after the command "nvflash --sync" only get "unknow device found"
Can anybody help me please?.
How can I get into SW recovery mode or something that shows some activity from the phone?.
Thanks and regards

i guess not much can be done. sent mine to the service center and got it back 3 days later fully functional. i guess it's easier to restore for LG since they have all the tools and magic keys.

Hello!
just happened to me.
apx mode you solved anything?
one can solve?
Thank you!

NVflash doesn't work, at least after upgrade to JB.
Before give your devices as bricked, try to enter in S/W without battery a few times and after with battery on.
Sometimes stressing the device have some results.
But the best you can do is take it to service.

Thanks gingerboy92. I follow your advice and my phone is in a LG service center now. Hope they can fix it.
I think that's the only safe way to recover it. Looks like Tegra 3 devices have security keys that are unique for each processor and without them you can't go further.
Amigo ruedaslocas, I tried many times to do what you say, unsuccessfully. Thanks anyway.

P990 total dead?

The info:
Windows 7 64bit
LG P990 stuck at a double LG boot screen. The phone enters download mode (pressing Vol down when plugging USB). Windows finds nothing when pressing Vol Up + Vol Down when connecting to USB.
Tried to NV flash but nothing happens which makes sense since windows don't find anything when double pressing the buttons and connecting it. Am I doing something wrong?

Hello,
Have you ever heard about this useful tool? http://forum.xda-developers.com/showthread.php?t=2020737
Repair your device with it. Also you should have installed all of the USB and APX drivers.

Yes I saw that and downloaded it. But my problem is that the PC doesn;t even find the phone connected. I have installed the drivers. And the phone does find the PC because if I only press down button it goes to download mode.

Use option "Repartition your device....". Follow the instructions.
/*Have you already tried to remove battery before plugging it in to the PC? And while you are plugging it in, you should hold VolDown and VolUp. Screen stays black but PC starts recognizing your device. At least, it works for me.*/

That's my problem...When pressing the buttons and connecting the phone(without battery) the PC (tried 2 systems) finds nothing at all.

need help maybe brick my lg d405n

Hi, I have a problem after uploading a lollipop phone LG logo is on and turns off factory reset does not help, re-upload KDZ by LG Flash Tool 2014 is not possible, because it does not see the phone, drivers installed with this topic: http: // forum. xda-developers.com/lg-l90/general/guide-flash-stock-kdz-offline-lg-l90-t2803479

Definitely it's driver's problem. Try them all you may find - https://yadi.sk/d/oC7kXZbvhc2Hh
https://yadi.sk/d/cqLxmIKTcFyH6
you have to get LGE AndroidNet USB drivers in your device list, when you connect phone to computer. remember, you have to connect in power off mode while pushing volume up button. Then you'll have to press "retry" button in LG KDZ install tool, and wait while install finishes

Thanks Man for help it works it was a problem with drivers

[Help] Bricked Lumia 1020 - Blank Screen - USB Undetected

My 1020 got bricked while flashing through WPInternals.
In the middle of the flashing the USB got disconnected and after that I have blank screen. The power button pressing does make phone vibrate. Also soft reset combination makes vibration. However I am not getting anything on my laptop on USB connection. No connection notification. Nothing on device manager. I tried combinations to get it detected but nothing works.
So the question is, Is there any way I can blindly send force flashing to one of the USB port and make it happen ?
JTAG is the only option ?

same me hichic

Flash Mode
Hello,
try this: power off/reset and power on holding vol-up key. You should get a flash-and-cogwheel sign on your display. If so, you cna reflash your (valid) .ffu file using PhoneImageDesigner/Lumia Flash Tools (->google!).
Are you sure your USB cable or port is not broken?
Best whishes,
Joachim

Okay, I have already tried that, since the USB got disconnected during boot loader flash, it does not display anything on the screen when I start with power button or reset combo. It only vibrates.

I have changed the cable too(USB flex cable of my lumia and USB cable too), It does charge battery, does keep flashing the start button once in a while when the cable is connected. I am sure USB is working fine. But not getting detected in PC.

Hello there... Any solution you found? I am stuck with my zuk z2 in same situation ?? any help ?

I have a similar problem.
What caused the black screen? -
History:
I booted to test mode at 2.5.033 ST, the phone got stucked at this menue there was no way to get out. TWRP Restore to Nandroid bougt only black screen after 2nd vibration and ZUK logo.
I fixed the Test mode bug, by flashing the ZUI 1.9.104 ST Stock ROM via QPST.
After the phone was "repaired" I unlocked the bootloader, installed TWRP, made a nandroid backup of fully stock ROM and restored a nandroid backup from before the test mode problem.
The nandroid restore was successful, I rebooted the phone and it was "dead". Black screen, only rebooting (perioldy vibrating) there was no end, until the battery was empty.
I got no luck to reach any mode with tricky button pressing (vol+ pwr; vol- pwr; vol+ vol- pwr; usb in vol-) nor Windows detecting the phone. That's why I decided to remove the back glass cover, to got access to the battery.
Now I'm able to get the phone detected by my PC.
What I did: disconnect the battery, connect the phone to my computer, pressed the vol- button and connect the battery.
This made my PC able to detect the phone, but no I have an other problem. Windows only detects the phone as "unknown usb device (device descriptor request failed)". I don't know any way to install the driver....
Maybe anyone is able to help me or has any tip?
Thanks!
Cheers,
m_atze

What id shown in unknown device.
Like ven_9102&dev_1234
Maybe with editing quallcom drivers for your device id, you can still install it.
and if luck qpst can recognize it as qualcomm debug mod

Alright bro, there is one method you can try.
http://zukfans.eu/community/threads/howto-flash-a-stock-zui-rom-zuk-z2-pro-z2121-only.57/
I assume your phone is a brick now. The only method you can use is the 9008 unbrick mode. (AKA QBST)
There are a few things you need to prepare before you save ur phone. U need to download the require application that the website provided above, after you set everything up,
make sure you download the latest 2.5 QBST rom,
http://bbs.lenovomobile.cn/z2pro/t554654/
Because ur phone wont be able to enter 9008 through software, thus u need to do the following.
1. Load the content XML fille,
2.Turn off your phone. After it's fully shutdown
3. press and hold the volume up button for 3 seconds
4. press power button while hold the volume up (press it for 0.5second and keep holding it)
5. after 0.5 seconds, plug in the usb right away
6. the QFIL tool should appear the Qualcomm usb QD loader
7. the download button should turn blue
8. flash it and wait for reboot

Thanks for your tip.
I followed your described procedure, but the phone will not be recocnized by the PC.
1st: I loaded QFIL XML file. (By the way this tut is made by me)
2nd: I disconnected the battery (The phone can't be turned off normally!)
3rd, 4th, 5th
6th: nothing happend!
7th: "-"
8th: "-"
The only way the phone will detected by the PC:
1st: disconnect battery
2nd: plug in USB (PC and Phone)
3rd: press VOL+ or VOL- or PWR button (doesn't matter which one)
4th: connect battery
5th: detected as "unknown usb device (device descriptor request failed)"

I will report the result.

OK. I made the deepflash cable.
After using it there is no difference between pressing one of the button combinations I recently mentioned (VOL+ or VOL- or PWR).
The phone will be detected as Unknown device. After intalling my modified driver to match the unknown ID, QFIL don't detect the COM Port.

Hello had the same problem, only with the difference that my battery was not completely discharged.
What has helped:
1 Start QFIL Tool
2 Press the volume +
3 Connect the original cable to the PC
4 QFIL Tool recognized the phone and I could play an original Rome.

Ps. Is now the battery cover (glass) broken?

No, I used a hairdryer, a razorblade, plastic tool and a suction cup to lift the backcover glass.
The glass is fully intact no damages.

You have good nerves. I would not have expected that.
But in the end, it does not matter if it does not start anymore.
Thank you again for your great instructions for playing and rooting the mobile phone.
I hope you get your phone back.
Mfg

Good and bad news
The guy unbricked the phone successfully, I received it today.
Now I have an other problem:
The phone is very very slow and laggy now.
The problem occurs everywere, Recovery, boot (the bootlogo laggs), booted System, also the test mode laggs now
Furthermore the sceen flickers sometimes and at the right side the sceen is mirrored sometimes.
Did anyone has an idea?
What I did today:
reflash through qfil
1.9.104_ST
2.3.044_ST
ZUI_2.5.335_ST

Hi m_atze, I am exactly in the same situation as You. After using deep flash cable method, I got "unknown usb device (device descriptor request failed)". Could You tell me what was the solution to unbrick the phone?
