[Q] Hard Brick D800 - Please Help! At a loss

Any help is appreciated! First some background:
Flashed device to stock using KK 4.4 version d80020c following steps found here http://forum.xda-developers.com/showthread.php?t=2432476. Successfully rooted using directions (and ioroot25) found here https://www.youtube.com/watch?v=HKuedInhdjU&noredirect=1.
Here's where I got into trouble...Downloaded TWRP 2.7 recovery img and flashed via Flashify. Since this step, my D800 has the exact same symptoms found on this thread http://forum.xda-developers.com/showthread.php?t=2582142.
- No download mode (tried many times)
- No recovery (tried many times also)
- Secure booting error
- LG detected as qhsusb_bulk in device manager
- Device is recognized as 15 different drives, one of which contains a folder named image with 79 different files being .B0X files and Microsoft Access Add-in Data files
- Upon restarting, LG logo with secure booting error, then the screen goes black while your phone is still on
I've followed the steps in the thread that matches my G2's symptoms, run ubuntu 13.1 in VM, apply usb filters for my device which is then recognized as either LG Electonics Inc. QHUSB_BULK or Unknown Device 05C6:9006 when running in VM.
Upon running command ls /dev/sd* in VM Ubuntu Terminal, all that is returned is /dev/sda /dev/sda1 /dev/sda2 /dev/sda5 which are the partitions for Ubuntu, no LG.
I've tried to download and update the Qualcomm drivers, device manager tells me that the drivers were recognized, but cannot be installed and do not pass the hash check (Note: PC is running Windows 8.1).
I've spent over 12 hours on this trying to fix this problem, researched and searched everywhere. If I could get ubuntu to recognize the device, I would be able to continue on with the instructions on this thread http://forum.xda-developers.com/showthread.php?t=2582142.
Links for windows 8 qualcomm drivers, suggestions on how to get the device recognized in ubuntu vm, experiences from others in similar situation, or any with experience working with LG to get a repair done if I'm SOL (as in eMMC is fried) would be so helpful right now.
Thank you all!

After flashing recovery did you flash a patched kernel to boot stock kk?

I had the same, also with a lot of drives etc.
Screen is black but low backlighted?
Then try with pluged USB Cabel in Phone, hold Power button until screen is realy off, then hold the Power Up Button and plug Cabel into PC.
So I got download mode after I tryed many times

I had problems a few weeks ago getting mine to go into Download mode... turned out that the cable I was using was great for charging, but sucked for everything else. Once I switched to a different cable things worked fine and I was able to load D80010c on the device.
I was running D80020c this morning (with the D80010c boot.img to have a custom recovery) and decided to do an update. Since you can't load D80020k if you have the older bootloader I went all the way back to D80010c, updated to D80010o, D80010q, D80020c and finally D80020k. I was able to root that using IOroot and have restored everything back onto my phone.

Thanks so much for the responses! I've tried endlessly to get the device into download mode, and tried a new cable to no avail. Any other suggestions?

The URL you've linked to will help you solve your problem.
So once you power off your device, hold volume down and power till the lg logo shows, then release shortly and hold them again together till the white window with "factory reset appears", you should notice a text behind the white screen it's fine. So right now when you think it's gonna enter recovery mode the screen is gray(not black), now you connect your device to your ubuntu or whichever linux. You will notice the screen repeatelly blinking when linux is trying to automount the partitions. Figure out which device it is according to the messages it throws. (sdc, sdb, sdX)
This way you should proceed according to the instructions on the thread you linked.
d800 partitions are here

Still no luck

Thanks for your advice.
I got the white screen asking whether or not I want to perform a factory reset. If I choose No, the phone sends me right to the LG Logo with the error screen. If I choose Yes, it does the same thing. If I plug my phone into my computer while on the white screen asking if I want to perform a factory reset, the device isn't recognized and the PC doesn't see it as plugged in or mounted. I'm not sure what you mean by the timing of when I should try to plug in my device. Thanks again for all your help.

As soon as in the background of the white menu (factory reset) the secure boot appear plug it in. I'm not sure how much usb filter helps you(maybe it does) but try installing ubuntu over WUBI installer so your win remains. Or at least try ubuntu from usb stick. So you can know for sure if it's working.

Hi Sneaky E. I have the same issue you have. I'll be following your thread. If I figure anything out I'll let you know. I am also having an issue getting mine to charge now. Have you tried downgrading your TWRP?

VirtualBox Error
VirtualBox recognizes the device is plugged in, but won't allow me to push the device for use in linux. I keep getting this error message:

I've tried all USB ports, 2.0 and 3.0. I feel like if I can get past this there should be no reason linux can't see the partitions in the phone. Please Help!!!

Ok so thank you for your help so far. I was able to install Linux on a USB drive and ran the commands and pushed appropriate files from there. I pushed all files including recover.img but the phone will not boot into recovery. Please help!
Thank you!

you are not alone dude. i had the same issue since sunday and i have spent almost 46 hours already trying to restore my LG G2 F320S korean model.
i followed that instruction in linux, everything went well but then I ended up with a phone not going past the LG logo. the screen no longer dims like how it used to with the secure boot fail error. again, it stucked at the LG logo and thats it.
pressing the 3 buttons though for 5 seconds shows a white screen with 3 options and a bar code under.
but all of these options will just take me back to the LG logo.
I went to a phone technician today, and they said the doing a JTAG fix is the only way to resolve the problem because after trying to fix it with linux, it is no longer identified by my PC.
what are your solutions so far?
anyways before this issue came up, i tried to flash TWRP using flashify, it failed. then went back up. tried to update the OS via OTA then thats it.
i home someone could help us out.

Mode download doesn't work

Hello,
I want upgrade my LG G2 with a new rom 5.xX
This phone have only the operator update. No custom, no trwp, nothing...
I installed drivers and when i want access to download mode. I can't. I use the good proccess with vol up then plug usb cable always with vol up presses.
follow this procces after a little moment my phone show me battery logo charging.
So i can't access to download mode.
I would use this process
t was NOT bricked. I finally tried playing around with the LG Mobile Support Tool (B2CAppSetup.exe). Of course it detected that my phone already had the latest firmware from T-Mobile, but then I clicked Options>Upgrade Recovery.
It downloaded for a while then I noticed it had put my phone into download mode (it said "Rooted" in red letters at the bottom). Then it flashed the same firmware over and I immediately tested, it entered download mode right away. But I didn't end up needing that as Stumproot was able to brute force it now after the recovery flash.
Anyway, I couldn't find an answer anywhere else. Most results also have a bricked phone, but that wasn't my issue. This solved my problem and maybe it could work for others.
but it's impossible for me to install B2appsetup on my pc the installation begin then stop after 5s then nothing.
I have Win 10.
Do you have a solution for me , please??

[GUIDE] [d855] How To Install Lineage OS - A Compilation (Downgrade/Root/TWRP/GApps)

*EVERY ACTION YOU PERFORM FOLLOWING THIS GUIDE IS AT YOUR OWN RISK*
That to be said, let's start: i am currently running the latest official nightly build on my d855 and it took me a while to get there. I couldn't find any (real) step-by-step-guide, where i would not have to google any errors or anything else.
Everything you find here is NOT my own knowledge, it is just compilation of sources, that i found on the internet.
Note:
Android 6.0: if you are on 6.0 and you always updated so you're on the latest security-patch-level the one-click-root-method won't work. I recommend downgrading your phone, which will be explained in the following.
Android 5.0: if you're on 5.0 you need to upgrade to 6.0 anyways, bc you need a different baseband-version to install LineageOS. This will also be explained in the following.
1. Make a backup of your phone
this is recommended, although i didn't do this, this is why i am not gonna explain it one here. I just saved my pics and contacts and did a factory reset, restarted my phone, did all the "first time turned on stuff" and connected to my wifi.
Note: Make sure your phone is charged to 60% at least
2. Download the following
a. Download LG G3 Drivers 4.0.4 and install them (i believe there are more recent ones, but this worked for me)
b. Download LG UP
- Download: LG UP Ver. 1.14: LGUP_Install_Ver_1_14_3.msi and LGUP_8974_DLL_Ver_0_5.MSI
- Make sure to install the DLL first and then the other .msi
SOURCE: Thanks to hyelton
c. Download the proper KDZ for you phone.
Note: I got this infos from a german site.
This is the 30C KDZ for the 32gb AND 16gb version: Download here
SOURCE: Thanks to mr bo
3. Downgrade/Upgrade your android-version
1. Turn off your phone.
2. Run LG UP (the tool you just installed) and press okay when you see the error message, that no phone is connected.
3. Press "Volume Up" on your phone and HOLD it, connect your phone to you computer via USB 2.0 PORT! This is important, bc connecting via 3.0 won't let LG UP recognize your phone.
4. Your phone is now in download-mode and LG UP should have recognized your phone.
5. Press SELECT, click on UPGRADE, then click on FILE PATH, choose you prefered .KDZ.
6. i recommend refurbishing your phone (This will wipe your entire system and make a clean install).
CLOSE LG UP and start it back up. The .KDZ should still be there. Now select REFURBISH and click on START. Wait until 100% completed and you phone has booted up completely.
Source and further information: Hail hyelton!
Also here is a youtube video: Thanks to kiaTech
4. Root your phone
1. Download the latest kingroot.apk from here.
2. Connect your phone (turned on, after all the "first time turned on stuff") and move the .apk to your Download-folder.
3. Open the (stock) filemanager on your phone and navigate to Downloads.
4. Install the kingroot.apk (enable third party .apk, when asked)
5. Open the app and root your phone (it's simple, believe me).
6. Your phone is now rooted (leave it turned on, DON'T restart)
5. Install TWRP and update to the latest version
1. Download this pack and unzip it.
2. Move the AutoRecMMD855.apk to your phone and install it just like kingroot.apk before.
3. Open the app and follow the instructions.
4. You now got TWRP on your phone.
SOURCE for #4 and #5 till here: Thanks to tute123456
5. Boot into recovery mode (either with the app itself i think or manually. If you have to do it manually. Turn of your phone. Press POWER and VOLUME DOWN at the same time until the screen shows soemthing. Release and immideatly press again. Your phne will ask you if you want to FACTORY RESET. Press YES and YES. If everything is working properly, TWRP should start up).
6. Connect your phone and download the latest TWRP.img you. In example here's the european one Latest LG G3 TWRP EUROPE
7. I assume you never disconnected your phone since moving kingroot.apk to it. So now you just move the TWRP.img to your Download folder.
8. Choose INSTALL on your phone and search for the TWRP.img. Select RECOVERY and flash it.
9. Choose REBOOT and then RECOVERY.
10. Your phone will boot into TWRP again. It should be updated to the latest version 3.0.2-0.
SOURCE: Thanks to everyone who contributed
6. Flash LineageOS and install GApps
1. Download the latest version of LineageOS (nightly) from here
Optional: make a backup of your phone using TWRP and safe it on your pc or internal SD Card, bc in the next step you will wipe your entire system, to get a clean installation.
2. Press WIPE in TWRP and select ADVANCED WIPE. Select everything but "Micro SD Card" and perform the wipe. This will wipe your entire system!
3. Move the .zip file to the Download folder on your phone and press INSTALL in TWRP. Search for the .zip and flash it.
Note: you'll see two red error messages. This is normal!
4. Wipe cache and dalvik as recommended.
5. Download your desired Open GApps package from here. Use "ARM" and "7.1", i recommend the "mini"-package.
6. Move the downloaded file to your Download folder on your phone and flash it just like you did the LineageOS file.
7. Wipe cache and dalvik.
8. In the main menu of TWRP choose REBOOT and then SYSTEM.
9. It will take a while to boot up, don't worry, just leave it there.
10. You succesfully installed the latest LineageOS build on your phone - you can now unplug your phone from your PC also :good:

Hi pheb92,
Big Thank You, If I had to do it bymyself it would have take me hours!!
-3. Downgrade/Upgrade your android-version -- I had trouble finding the right DLL on my Windows 10 system, onetime I managed to use LG - Up. At that moment the DLL loaded was 4.2.0.0. date 23-8-2016 device name "LGE AndroidNet USB Serial Port (COM6)"
- 6. Flash LineageOS and install GApps -- I flashed straight from a uSD card inserted in the LG G3.
Thank you for the great Setp-by-Step!

as far as i know LineageOS doesn't have an inbuilt root access (so far) like cyanogenmod did. you can only enable root access via adb in the developer options.
i did not root lineageOS myself so far, but you can try the following:
- Download superSU.zip from their official website and flash it via TWRP.
i would appreciate it, if you would share the outcome

LineageOS does have built in root management, but it doesn't ship rooted by default.
This change was made so SafetyNet doesn't get triggered by root and you can use Android Pay on your device.
Just download the su zip from LineageOS download page and flash.

I am stuck on this step. My d855 gets into download mode and LG UP recognizes the phone, but I'm getting the "You have to select a known model, please" error in LG UP. I have uninstalled and reinstalled LG UP and the DLL multiple times, same problem. I also tried uninstalling and reinstalling the driver, and I tried other drivers, same problem. I tried the tip in another thread (https://forum.xda-developers.com/showthread.php?t=2785089) to change the port to COM41 in device manager, but it didn't help. Btw I also unrooted my d855 (it has 4.4.2 currently) in case that's why the tool couldn't recognize it. Please help!!
Also @hyelton if you can help...
 @engmia since you were helping me earlier...

hi supperbowl,
are you sure you're using a USB 2.0 port and the original LG-USB-Cable, that came with the phone?
as far as i experienced it, 4.4.2 should not be an issue.

Have you tried it with the phone booted into the OS? With USB debugging on? Also if running 4.4.2 why not just use the old method?

No I've only tried it with download mode. I have USB debugging enabled in the OS. I am now trying the old method with LG flash tool, so far I'm getting stuck with the LG mobile support tool which keeps saying "upgrade stopped due to an error".
Edit: LG UP doesn't recognize the handset at all with it booted into the OS.

If it's at least detecting unknown device while in download mode it most definitely should show up in lgup when boot up.
Choose MTP mode? And it's not just in "charging mode" or try vice versa?

what also worked for me once was just retrying the process --> turn off, go into LG UP, go into download-mode. if LG UP does not recognize the phone: put the battery out of your phone, close LG UP and start the process again (also with different USB ports and other USB-Cables).

You did not installed LG UP DLL properly
supperbowl said:
I am stuck on this step. My d855 gets into download mode and LG UP recognizes the phone, but I'm getting the "You have to select a known model, please" error in LG UP. I have uninstalled and reinstalled LG UP and the DLL multiple times, same problem. I also tried uninstalling and reinstalling the driver, and I tried other drivers, same problem. I tried the tip in another thread (https://forum.xda-developers.com/showthread.php?t=2785089) to change the port to COM41 in device manager, but it didn't help. Btw I also unrooted my d855 (it has 4.4.2 currently) in case that's why the tool couldn't recognize it. Please help!!
Also @hyelton if you can help...
@engmia since you were helping me earlier...
Thanks.

Bricked a G2 (D802) pretty unusual

Hello guys,
So I bricked my D802 , how? first it was bricked because of a wrong version of TWRP, untill here no problem, i tried many tutorials on how to go back to stock rom, then i found that it was a Qualcom thing problem, so I found that tutorial about replacing the .img files etc... , pretty easy, i could enter the recovery menu, but it had no rom, i downloaded the stock rom kdz file , started flashing it, then, for some dumb reason the flashing stopped, I ... plug out the usb cable... I didn't notice untill I saw that the program froze, and now the phone is stuck at the LG logo, impossible to do anything, pc doesn't recognize it, can't go to recovery menu, can someone help me please? or at least tell me if I should just throw that phone or keep it if it has a chance of living a bit longer

I had a very similar problem with it getting stuck at the logo after pushing supersu to the phone. I followed Supersport every single step of the way in his video. I think his links are the only valid ones online now, so just download them and reflash your phone. If your G2 is anything like mine, drivers will never appear to be installed correctly and it never restarts, only shuts down.
His method is:
1) Download and install LG drivers on PC
2) Download and install the flash tool and patch it
3) Download and load the .tot and .dll files into the flash tool
4) Enter download mode on G2 by holding volume up while connecting USB
5) Switch G2 Com port to 41 in device manager
6) Once Flash tool shows that all ports are ready, power down G2 and disconnect
7) Hold volume up and reconnect to get back into download mode
8) LG Flash tool starts flashing
9) Complete
Note: If your G2 was screwed up as bad as mine, it'll say failed but all the main system files will load to the device before it restarts and it'll even shut itself off while doing it's installation on first reboot. Mine somehow was still revived from this state with his method.

Lenovo Tab 3 8 (TB3-850M) - Hard Bricked

Hi,
It looks my tablet got hardbricked. Apparently, it looks like it was turned off completely automatically, when in sleep mode. When it's powered off now - pressing power button for a while makes nothing. When connected to charger - white LED flash is blinking only and when trying to power on, and there is no "Lenovo" logo at all. I've tried some of "power cycle" tutorials - but no luck. Once, when using power button, tablet was vibrating crazily and screen blinked, but it was shut down after moment.
Sorry, if there is existing similar thread - this tablet is not very popular. If there is any "magic trick" to make it work, I'll be grateful, if now - probably I'll need to flash new firmware. Currently, I'm discharging it completely.
Best regards.

Are you still bricked? There is the firmware flashing method using SP Flash Tool which restores both the 850F & 850M to full factory condition. Let me know if you need the method and I'll get you links to the guides here on XDA.

Yes. I've asked for help guy from unauthorized repair service, he said device is completely bricked, probably EEPROM chip is broken. But ok, you can send me this instruction of course

I've had two 850F devices hard bricked and was able to recover using SP Flash Tool and a stock firmware package. I'll get you the method posted here. But, out of curiosity, how did you hard brick yours?
(The 850F is pretty much an 850M without SIM/data connectivity support. They also have slightly different chipsets, but many of the specs are very similar. So, I know the method will work on both variants of the Tab3 8.

Hey, thanks for you reply! As I'm not owner of the tablet, it's hard to say how it was bricked. It was on stock firmware, it was not rooted and TWRP was not installed. I've helped to configure this tablet, tablet was turned off everyday at 11PM automatically, and powered on manually, by device owner. She said sometimes instead of powering on to Android, it was booting into FASTBOOT mode (green android image). Once, it just failed to boot, without any reaction. I've tried to recover it using Windows machine, when plugging it into computer (no matter, with, or without Vol+ pressed) it was recognized as Unknown device (instead of Qualcomm, or something). I've tried many drivers - but with no luck, device was not recognized. Also, I've tried 2 machines with Win7 & Windows XP. I've managed to reboot device using power key long pressed, but starting from this point device was not recognized at all... When plugged into USB, nothing was happening. Service guy said he was able to make his computer recognize device using some technical cable plugged directly with motherboard, but all methods to flash firmware failed. He said probably EEPROM chip is broken completely and replacing this part is half of device cost. Thing is, this tablet was bought from China - so no guarantee at all. Well, probably she need to buy next tablet from local electronic store...

Yeah, the service guy is full of it without any doubt. Using a modded fastboot cable, like he was likely referring to, will not only fail to push firmware to the eMMC, but will very likely damage or corrupt the partition index. I can't promise my method will work, but I can say with some certainty that it will. Ok, first things firstt: install the latest SP Flash Tool on your Windows PC or laptop. Also, you will need to install the latest vCOM drivers (for the Mediatek chipset). Do you know how to do this or do you need links? I can post a link for unbricking the 850F, which has been reported to work on 850M, but the thread is a bit erratic and non-concise. It will be much easier if you and I do this step by step. Also, you will need a stock firmware package for your 850M (build version is not relevant). Do you have one or do you need a link?
In a nutshell, this method will do an emergency recovery by directly pushing a stock firmware package to the device's eMMC flash memory. Although your PC is not currently recognizing your device, the vCOM drivers/SP Flash Tool, & your volume down button, will force recognition of the Mediatek chipset. Again, I cannot promise this will be successful, but I can say I've not yet seen a single hard bricked Tab 3 that could not be recovered from a hard brick this way.
Step 1 -- install the latest vCom drivers on your Windows (7, 8.1, or 10) PC/laptop. Here is an excellent XDA tutorial that provides sources and detailed instructions. https://forum-xda--developers-com.c...-10-mtk-vcom-usb-drivers-32-64-t3267033/page1 Sorry for the lengthy url.
Step 2 -- install the latest SP Flash Tool on your PC or laptop. Go to this website for download sources; https://spflashtool.com/
Step 3 -- download a stock firmware package for your TB3-850M. This is a link for a solid firmware package, confirmed to work (take note that build version isn't a factor. The SP Flash Tool will push a downgrade, upgrade, or collateral installation {same build version}): https://cloud.mail.ru/public/LHhe/NkpAi7WuL
When you've completed the above 3 steps, let me know and we will go forward with the firmware recovery process. :good:

I have the same issue. I dont know how but i got hard bricked completely. I was flashing rom on it and it got bricked. Now service centre guy is saying that i have to change motherboard altogether. But your post seems convincing. Please let me know the next detailed process.

i have the same issue.
one day stop working
