No need of patch.xml
[T-Mobile LG V10 Android Development] cambiala:
I already unlocked it, mine is a H901 with 5.1.1, and it is only possible to put that rom and I can not find it., do you still have the LGH901AT-00-V10c-TMO-US-OCT-07-2015-ARB00 + 0.kdz? or a rom kdz 5.1.1 original ?. It is only possible to load that rom. Thank you.
[T-Mobile LG V10 Android Development] PramodJT:
I don't have H901, mine is H961N.
[T-Mobile LG V10 Android Development] PramodJT:
Sir, I used your code to create the full 61GB image for my bricked H961N. The phone's emmc seem to be fried, so I used SDcard to boot the phone. The problem is, the phone is shown as H960A in LGUP. I need some help regarding this. Thank you.
[T-Mobile LG V10 Android Development] darkcremona:
Can i used 16gb sdcard class 10? I already tried with 16gb, and write dump img to it. But still no work. Format to Exfat or FAT32??
[T-Mobile LG V10 Android Development] black_horse_88:
Thank you very much!

Almost gave up and bought new board!

I bought a refurbished H901 that came with 5.1.1 VS990 board, updated to H901020J and bricked.

Flashed all H901 firmware, non worked.

I tried your method with VS990 firmware, my phone booted up!

Can't thank you enough!!

Even though it's pretty much useless as bricked now lol -_-
[T-Mobile LG V10 Android Development] xzlo:
Good day. I have the same case ... you can throw off the files that are written on the card for vs990

Добрый день. У меня такой же случай ... вы можете сбросить файлы, которые написаны на карточке для vs990
[T-Mobile LG V10 Android Development] black_horse_88:
The SD trick did not work with me, I used this method:

https://xdaforums.com/tmobile-lg-v10/general/unbrick-h901-f600l-board-2017-t3635697

Download the attachment files:

1- Without battery, hold volume + and plug the PC USB to boot in to Qualcomm and install driver manually ( make sure driver is not marked with yellow triangle ) If Driver 1 doesn't work try Driver 2, not sure which one I used.

2-Download the F600L20e firmware from here https://lg-firmwares.com/

3- Open LG extractor, open F600L20e, check all files and extract to DZ ( make sure to choose target folder)

4- Move XML file to the DZ folder.

5- Install QFIL and open it ( C:\Program Files (x86)\Qualcomm\QPST\bin\QFIL.exe)

6-Select programmer: Select the EMMC file

Select build : Select the XML file in the DZ folder, and cancel the patch.

7- Click on download and wait few minutes.

8- When download succeed, remove the USB and insert battery.

9- Hold volume + and insert the USB cable, you should see Korean download mode.

10- Download firmware refers to your main board "VS990"

11- Use LG extractor to turn the KDZ files to DZ.

12- With LGUP flash the VS990 DZ file to your H901 and wait, it should boot right after.

Notes:

If you fail to flash QFIL try reinstalling driver or QFIL, or try different version if this one doesn't work with you.

If you get VPN error on boot, try different firmware.
[T-Mobile LG V10 Android Development] xzlo:
where to get the Patch File.xml file?
[T-Mobile LG V10 Android Development] xzlo:
if to cancel patch, then not active download
[T-Mobile LG V10 Android Development] black_horse_88:
In Qfil.

Do you see Qualcomm 9008 port?

If not reinstall the driver.

Do you see the XML file like in picture after cancel the patch?

If not, you are using an old QFIL.

I tried flashing different official rom to avoid the VPN error and now it's bricked again. undetected by PC at all.

Those locked bootloader ver loves to brick

Never had any problem flashing the H90120J so many times -_-

[T-Mobile LG V10 Android Development] PramodJT:
check this below link. Use H961N xml and mbn files attached. Download QPST 2.7.460 to flash all the bin files listed in the xml file. To get the bin files, use WindowsLGFirmwareExtract-1.2.6.1 (it will extract your kdz to dz and finally to bins). Rename the bins to match the names given in the xml file.

Use F600s xml file. Don't use others, they don't match. Or modify it to match yours. You need to set the memory locations correctly to match your phone's partitions, otherwise it won't work.

Hi guys

Dear [MENTION=4965298]tungkick[/MENTION]

A friend of mine has a LG G3 D855 with the same issue of demigod-crash-handler screen message error :(

I think that the .img file linked in OP post cannot be used because it is related to another model

Do you know where may I download the relevant file for LG G3 model ?

Do you have the image file ? And if so... make it available?

Would be much appreciated.

THANK YOU!!!!!!!!!
[T-Mobile LG V10 Android Development] paulsg63:
OK.. maybe I am unclear what a hardbrick is... I did the stock recovery from another post and all was working fine. My phone then downloaded the MM update. And lets just say.. it was told go ahead and update. When I got to the phone.. it was off. and would not come back on. Even when the power cord was put in, nothing. no indication of charging.. nothing on the screen at all. I assumed this was a hardbrick.

So I tried this method to recover. have the SD card with the image. put it in the phone, put in the battery, tried the "vol-up" button. But still nothing at all on the screen.. no indication of power at all.

I'm now wondering if somehow the battery got wiped out and wont come back. Just weird.

Again, just wondering if my idea of a hardbrick isnt whats going on with my phone. But something else.

Thanks everyone for your help.
[T-Mobile LG V10 Android Development] demkantor:
Hardbrick is when your phone is useless as a brick - when caused by software/firmware failure there is sometimes a way to change this, our phones have a special Qualcomm USB mode, which is kind of a failsafe

This method is for this circumstance - you would plug phone into a Windows PC and a driver should recognise this mode, if it does then great - follow procedure

If not more troubleshooting is needed but if it is hardware than no go - unless somehow randomly it is a fried battery which i kinda doubt
[T-Mobile LG V10 Android Development] paulsg63:
OK.. somehow missed the "plug phone into PC".

Anyway.. did that. Then tried the volume up.. still nothing on the screen.

I even downloaded QFIL and when I plug the phone in the PC.. It sees the service port. but still wont show the loading screen... hell... NO screen... just dead.

I'm wondering if there is some kind of hardware issue.
[T-Mobile LG V10 Android Development] demkantor:
I don't believe anything will show up on phone

Once you plug phone into Windows PC you should see if it finds your device, check drivers, you need PC to recognize phone in Qualcomm USB mode to continue
[T-Mobile LG V10 Android Development] paulsg63:
When I plug in.. It shows up in PORTS as Qualcomm HS-USB QDLoader 9008 (com3)

I then tried the "volup" but nothing happened....
[T-Mobile LG V10 Android Development] demkantor:
Did you follow the steps prior to that? It won't bring you i to download mode until you do so

Just go through each step in op again
[T-Mobile LG V10 Android Development] paulsg63:
mode :(

Yes.... did the steps exactly.. but after I hold "volup" I dont get the download mode :(

hmmm
[T-Mobile LG V10 Android Development] demkantor:
Then i believe you will need to ask [MENTION=4965298]tungkick[/MENTION] for help, or someone else who went through this procedure
[T-Mobile LG V10 Android Development] paulsg63:
Yes.. looks like it... thanks for all the help so far..

If anyone has gone through this and could point out some gotcha's.. that would be cool.

I've gone through the steps.... but cant get past the "volup" to download mode step. :/
[T-Mobile LG V10 Android Development] supreme329:
This is exactly what I did:

1) Formatted sd card just for my own reassurance.

2) Wrote the dumph90120j.img to my sd card ( I personally used dotNetDiskImager_0.5.83.23)

3) Removed the sd card from my computer and inserted it into my phone.

4) Held the up button on my phone and connected it to the computer. Turned on and booted into download mode.

I also did some searching on the internet and found the latest qualcomm drivers. Now im not sure if this matters but im just telling you what my process was and it worked.

Also make sure your battery to your phone is some what charged.
[T-Mobile LG V10 Android Development] paulsg63:
I did all the same steps.. but when I get to where I hold in the up button and connect it to my computer... It never turns on... just nothing.

I see where it shows on my USB list in Device manager... but then phone never turns on.

I'm wondering if there is something more thats wrong with this phone.

Thanks for your help though..
[T-Mobile LG V10 Android Development] supreme329:
Hmmm yeah sounds like it. Have you tried a different sd card?
[T-Mobile LG V10 Android Development] paulsg63:
No.. I bought a brand new Samsung 32Gb.. just like the picture...

But I guess I can try

(edit)

So I tried to format it.. now it says its locked. When I look at it with DiskManger.. it shows a crap ton of partitions. In file Explorer, it shows an Image directory with all the files. so I think its ok.
[T-Mobile LG V10 Android Development] supreme329:
Thats a good sd card. Have you tried contacting tungkick on facebook?
[T-Mobile LG V10 Android Development] paulsg63:
OK.. Thanks... I sent a skype request..
[T-Mobile LG V10 Android Development] KanBorges:
Can you let me know what you did if you fixed it? I have the same problem. Mine wont go into download mode or do anything. :rolleyes:
[T-Mobile LG V10 Android Development] paulsg63:
well try as he might.... tungkick tried a bunch of things.. but it would never give me the download mode.. He thinks its my SD card reader.. having issues.

I dont know.. maybe..

I think I am just going to get a replacement phone.

Just dont want T-Mobile to know I was modding.. lol

Thanks everyone... looks like new phone time...
[T-Mobile LG V10 Android Development] OriginalShinken1:
You could try one more thing.

https://www.sdcard.org/downloads/formatter_4/

Anytime I have ever had an issue with reading an sd card, this has fixed it.

Does anyone remember the 32/64 SanDisk cards that kept unmounting mainly in samsung devices? This fixed that.

(and on a sidenote; I brought this to SanDisk's attention and they made it out like I'm the only one)

-sent using this app on this device.
[T-Mobile LG V10 Android Development] paulsg63:
OK.. received my replacement phone...

sending back the brick. Hope T-Mobile doesnt dig too deep.. (not that I think they will try or even could get into it anyway.)

But, again, I thank everyone who helped and tried to get this working.

Much appreciated.

[T-Mobile LG V10 Android Development] KanBorges:
Dude, same thing. Its no use. I talked to him and we couldn't figure it out. I sent mine to repair with LG. Go to their website and click the repair part and if your EMEI is clean they will take it to repair. The V10 came out in October last year so you should still be good for the 1 year manufacturers warranty. Good luck.

How to make dump.img?
[T-Mobile LG V10 Android Development] kazem2277:
i have h960A can you halp me ?
[T-Mobile LG V10 Android Development] emdroidle:
[MENTION=4965298]tungkick[/MENTION] how did you create the dumph90120j.img file?

The first slightly over 100MB is simply a dump of the H901's firmware. This can readily be obtained from the appropriate KDZ file. After the end of the aboot portion though it differs from the standard H901 firmware. Didn't appear to merely be padding with zeros, but I haven't looked that closely yet.

I'd like to recreate this for other members of the V10 family...

EDIT: Hmm, upon further examination I'm now forced to wonder if I'm looking at a bug in my code. Could perhaps be the dumph90120j.img file really is a straight copy of the first 1GB of the KDZ/firmware. Need to track this down since this could fix another observed problem...

EDIT2: More examination and I'm left suspecting what I spotted was an artifact of the tool tungkick used to create the dumph90120j.img file. This leaves me suspecting my tool may work better. This thread does give me some interesting suspicions.
[T-Mobile LG V10 Android Development] emdroidle:
Dunno, you've given no detail about the sort of "halp" you desire. I'm certainly not qualified to give mental help.

Note, these instructions are using experimental tools that have unverified reliability. They should work, but I don't have sample hardware in front of me to test. I'm also making theories based upon what I've observed of various tools and these theories may very well be wrong.

On the presumption you've got a H960A in 9008 mode, I may be able to provide some suggestions. Two resources are needed. First, get the appropriate KDZ file for your device (URLs for most devices are here). Since you've mentioned a H960A that would be this file.

Second, get a copy of my KDZ tools from here (this file). This will need Python installed.

Run these commands (adjust paths as appropriate for where you've downloaded things to):

> unkdz -f H960A20b_00_0817.kdz -s 0
> undz -f kdzextracted/H960A20b_00.dz -i

While the file "dzextracted/image.img" will be rather larger than the one tungkick provided for the H901, that is due to it being rather more complete. Only the first 1GB or so needs to be loaded onto a SD card, plug that into your phone and that should be sufficient to get your phone into download mode.

I'm left with a bunch of speculation based upon what has been described. Pretty clearly it appears Qualcomm's firmware is capable of booting from either an internal eMMC chip, or an external SD card (they're basically the same thing). I'm left wondering if it can be caused to boot from external SD even if the internal eMMC is valid. This could be extremely helpful for development since you could load your beta image onto a SD card and boot from there and not have to risk the internal memory.
[T-Mobile LG V10 Android Development] tungkick:
IF you have phone in hand h901)

Use command backup mmcblk0

adb shell

su

dd if=/dev/block/mmcblk0 of=/data/media/0/dumph901.img bs=1024 count=1048576

reboot phone then copy dump in phone memory.
[T-Mobile LG V10 Android Development] emdroidle:
Thanks, that answers that.

Now I'm left wondering whether the raw firmware images produced by `undz --image` can be used for this same purpose. Clearly there is a bit of change to the on-board flash during some phase of the phones life, but is the extra data genuinely needed to boot the phone? (I suspect not, but I lack certainty) I'll be examining the differences and seeing whether I can divine anything.
[T-Mobile LG V10 Android Development] devcon69:
Confirmed Emdroidle, your tool is working. But we needed at least 60GB free harddisk space when building the raw image file for V10 cause it has all the partitions including system and userdata. Download hdd guru raw tool and run it. Insert sdcard on pc and flash the raw image file to your sdcard. Yea flash it. Wait until hdd guru stops with an error at about 50-70%. Eject from pc and insert sdcard on your phone. Now try to access download mode if it works.

Your undz tool is a great tool for making dump files from compatible kdz files and for people who does not have a good phone for making backup.

Worked on bricked F600s when it was wrongly updated and got the Qloader 9008. But download mode does not stick cause of the Secure boot error bootloop. Same issue with the G4's who have the Qloader 9008 when they downgraded their phones or flashed a wrong bootloader. Still waiting for a fix for this.
[T-Mobile LG V10 Android Development] emdroidle:
Well, I do have another idea, but it seems a bit crazy and I consider it rather risky (but if your phone is already in bootloop, it might work). You might try the thread author's H901 image, while it isn't meant for a F600S, it should be self-consistent and due to sharing the same processor may be able to boot your F600S to the point of getting into download mode. At that point simply try using LGUP to install the F600S KDZ file. Failing that according to this thread using a hex-editor to replace the two instances of the string "F600S" (might be "LG-F600S") with "LG-H901" should convince the download mode of the H901 image to install the F600S image.

I'm suggesting what I consider whacky ideas, but they might just work. :fingers-crossed: Now I'm coming up with more ideas of things to look at that might just produce results...
[T-Mobile LG V10 Android Development] emdroidle:
What was the state of your phone at the time you made the backup referenced in the first post? Pretty obviously it was rooted, but was the bootloader unlocked at the time? Do you have an image with the bootloader in the other state? (I'm curious whether we can identify which portion(s) are modified when the bootloader is locked/unlocked)

I'm trying to come up with ideas for how to unlock other V10 devices. Might be easiest to grab the H901 bootloader image and merge it with the kernel and system image from another device. Trick is to have the bootloader unlocked first so it doesn't object to the other device's kernel.
[T-Mobile LG V10 Android Development] devcon69:
:good: Tungkik's H901 backup does not work. I've tried that already. Dump from F600S and F600K enables download mode but will only run for 2-3 seconds cause of the boot error.
[T-Mobile LG V10 Android Development] Sippi4x4man:
did you ever get this fixed? I have the same problem, this method does not fix it
[T-Mobile LG V10 Android Development] emdroidle:
As long as your computer uses anything other than FAT for it's main storage, while it may appear to be a 60GB+ file, it won't actually take that much space. If you look at the free space, it should only decrease by around 4GB. The file is "sparse", so most of it doesn't take storage space. Alas, this doesn't solve anything. :(

I got some examination of the image done. Looks like the image has boot, recovery, factory, and system areas modified. The amount of modification means trying to identify which portion unlocks the bootloader isn't going to happen from this image, too big of a haystack.

Based on some of the subsequent reports, I'm left suspecting while the bootloader explicitly looks for the unlock flag in the on-board eMMC chip. It may not accept that off of a SD card. How extensive was the damage to the on-board storage that the image was able to recover from? Was the boot area corrupted or incorrectly modified? Was the recovery area corrupted or incorrectly modified? (question is which areas can be loaded off a SD card and which areas must be loaded off internal eMMC)

Any idea of the extent of corruption/damage to the internal eMMC? As noted above, it could be the bootloader wants to load at least some of the boot data from the on-board eMMC, if the boot area was unintentionally modified it may be impossible to get a match between the bootloader and kernel and we're sunk. :(

I'm going to have to echo the above. You can hope bilek06 shows up and either reports steps or gives enough data to recreate what was done... :(

Hmm, interesting reading one starts finding when looking at information on 9008 mode...
[T-Mobile LG V10 Android Development] Sippi4x4man:
My situation was unique I think... I did not attempt this "fix" because I flashed something I wasn't suppose to. While visiting the Santa Monica Pier in CA, I was taking a ton of pictures pretty quickly. Most of them were panorama's and I was clicking the capture button very rapidly to get as many photos as possible. Out of nowhere, the phone froze while taking a photo, so I just pulled the battery and rebooted. Several photos later and the same thing happened. This would eventually happen 3-4 times and the last time it did not recover. When I pulled the battery the last time, all I would get is the Red/Whi LG logo and the phone would boot no further.

I attempted to flash the Stock KDZ and same result...Just the LG screen and it wouldn't boot any further.

I was stock-rooted on H901j build with an unlocked bootloader. When I attempted this "fix", I got the same exact result as before except that now I have the Red text in the top left that says something like "boot image verification fail" and it this would just repeat over and over until the battery was pulled.

I eventually had to go to T-Mobile on a Sunday after I flew back home and filed a Warrany claim and now I have a new V10...

Just to share my experience....
