What part you don't understand in vBUS is one way? That's a hardware thing. This can be easily achieved by using diodes to prevent electricity from flowing in two directions. If you can change the hardware to break that restriction then great, but the schemas don't lie, the line is one way only.
[Windows 10 Mobile] GeoffreyK:
When I project my screen over USB to my computer (both running Redstone), if I try to move my mouse or type anything, I get a message saying my phone (Lumia 640) is not capable of receiving mouse input or key strokes over the USB port. I guess this is a good indication that there is no two-way stream that can be enabled simultaneously. On the other hand, I get the same message if I project my screen wirelessly, so maybe it's just a question of the phone not having the right protocol. (TeamViewer can send keystrokes back to the phone over Wireless.)
[Windows 10 Mobile] Shad0wKn1ght93:
True, but I think in theory you *could* work around that. It would be pretty ridiculous, but if you manually power the "ID Pin" of the Guest Device and force the Windows Phone into Host mode, it *SHOULD* work. xD

Only proper firmware update can unlock it
[Windows 10 Mobile] ElectroSix:

Hi guys,

i came up with a temporary to unbrick LG G4 H815 , you just need a 32 GB SD card ( i used Sandisk 10 class) , the dump that i will link , and Win32 disk Imager, the SD card must low level formatted.

1- download this dump

http://www.4shared.com/rar/NzSqsBziba/EMMC_ROM1_032G74_1803230737_00.html

2- put the SD card in the PC and chose the dump file and write ( run as admin ):

3- put the sd card in the phone plug the battery and power on.

Bam :) :D

unbrick H811 T-MOBILe

how i can get H811 LG G4 Dump file...?
[G4 Android Development] bender_007:
From the 1st post?
[G4 Android Development] T.E.I.M:
i need H811 Model dump file...the 1st one its for h815 Euro Model!!!!!
[G4 Android Development] bender_007:
Ah I see now. You have to ask someone from 811 thread to dump it for you. Your keyboard "!" got stuck also?
[G4 Android Development] aes1151:
Is the SD Card must be 32 GB?
[G4 Android Development] BySezerSimsek:
no, 8 gb enough
[G4 Android Development] aes1151:
Thanks for the answer.

I tried 8GB SD card before and it working but gave me an error (security Error) when I went to get into Download mode ..or gave Boot loop at normal mode ..

Finally it stopped working .. also when I repeated the steps again not running any more

(but with another dump file.)
[G4 Android Development] culot:
I posted one here for h811 v20o. It booted mine up.
[G4 Android Development] T.E.I.M:
thanx :D:D

size of sd-card you used....?

32 or 8 Go
[G4 Android Development] culot:
32gb.
[G4 Android Development] T.E.I.M:
can i use the full dump "Dump_H811_1GB.img"

http://www.gsm-file.com/files/dumph8111gbzip-2702.html

or i must use dump file *.BIN that i cant find it

link me *.bin file for h811
[G4 Android Development] culot:
That specific dump did not work at all for me. The singleimage.bin I posted worked for me right away. It's inside the archive i linked in that post.

---------- Post added at 03:15 PM ---------- Previous post was at 02:58 PM ----------

Image is is q.zip in the download link in that post.
[G4 Android Development] T.E.I.M:
thanx
[G4 Android Development] ItzShadowz:
Awesome! I'm sure you will be a lifesaver for many people. Now I don't have to worry as much if I try to port ROMs.

BTW, just curious, but does the SD card execute the dump when the phone boots up or something? (just curious as to how it works by putting a dump on an external sd card).

Thanks :)

Plz help me in this meter i tried all kdz firmwares and also custom roms but still facing this problem. My phone model is h811.
[G4 Android Development] steso90:
Any way the same method would work for other models like galaxy s4? Ive bricked it and got qualcom and some numbers.

I have H811. It has V20o but i mistakenly flashed Modem, Boot and Bootloader of V20i. Now its dead. No Download mode. No Charge Light No Boot. I have tried this SD Card Method but nothing happens when i connect my phone.

My system only detects "Qualcomm HS-USB QDLoader 9008" and nothing. Please help me
[G4 Android Development] limaecho:
Hi

Thanks for this.

So I have LG-H815 - Stock 20G ROM

This AM the phone turned off and won't start at all (nothing on screen, no LED). When I connect to computer it shows in Device Manager as Qualcomm HS-USB QDLoader 9008

Will this fix work for me?

Will this wipe my data?

I tried the freezer trick for 30mins or so and it starts up the phone for 2-3 mins with the boot logo only and then it turns off - dead again.

Its in the freezer again.

Also is it possible for you to upload somewhere else - as 4shared requires sign up.
[G4 Android Development] limaecho:
Bump! anyone?
[G4 Android Development] ReeS86:
Out of curiosity does this method of booting from the microsd card work for phones in a normal functioning state where the internal memory is able to boot with no issues? I'm wondering if we could use this to play around with some of the bootloader locked variants without causing a brick by flashing incompatible software (i.e. everything on the SD card). I have a Rogers H812 that has no warranty so I have to be careful.

[G4 Android Development] stojshic:
I don't get how to use this method when the phone doesn't even boot? When I connect it to PC it shows as 9008, only black screen. When I try to boot it with or without sd-card, it doesn't boot, only black screen. Am I doing something wrong, or....?

[G4 Android Development] ahmednsry:
i need to enter download mode which partition is do that

[G4 Android Development] Noksucow1:
You just need to use LG Flash tool and your respective KDZ file and make sure you use the unsigned file. If you have a TOT file you can flash any variant you want by changing the model number to match whatever your flashing to.
[G4 Android Development] rokaxis:
any idea how to get TOT file, I'm sorry again, help me
[G4 Android Development] Noksucow1:
You need to search for it on the internet. AFAIK there is only TOT files for the Sprint LS991 and the AT&T H810.
[G4 Android Development] alain57:
my G4 is bricked (first phone ever that I was not able to rescue :( )

I was playing some game, the screen freezed, i removed battery but the phone refused to boot)

So i rebooted recovery and eraze cache and dalvik cache... and without asking the phone rebooted ?

since them impossible to go into recovery or fastboot

I also tried this dump but did not help either :/

now I need to send the phone to LG... and for sure they will play dumb and say : hey the bootloader is unlocked... no warranty...

because YES the phone turn on and the LG logo (with the unlocked warning) displays... then nothing happen

even adb logcat did not recognize anything...
[G4 Android Development] rokaxis:
Hello I found the tot file for h818, but when trying to upload it gave me the same error that the file KDZ any idea
[G4 Android Development] Noksucow1:
OK, while I don't recommend flashing the wrong TOT here is how to accomplish this.

First get a free hex editor, open up the TOT file and search for "xVLG ", when you locate this string you will see the current model for the TOT file. Simply switch that to whatever model number your phone is and the phone will flash without any problems.

Also to flash the KDZ to a different model you can use LG Flash Tool and a no CRC check DLL file.
[G4 Android Development] softman20:
hello, did you got an answer ? im in the same case, thanks
[G4 Android Development] rokaxis:
hello, try several times TOT process to modify the file, edit the file with a hex dump, but only came to 79% in the mobile and the LGUP, it reaches 74% and introduces me this error.

[G4 Android Development] devcon69:
There are 2 names there to rename if you have that error or maybe it's because you are trying to downgrade. Try to find a tot that has a higher version from what was flashed on your bricked phone. I pm'ed you with regards to the download mode.

[G4 Android Development] Pterka:
Tried both exFAT and FAT32 cards - nothing changes.

As for me I don't understand how phone should know that it's FS is on SD now, and boot from it not from eMMC.

So... no charging, no download mode, no even screen backlight and "RELINK HS-USB QDLoader 9008 (COM22)" in Device Manager.

LG G4 H815 Singapore version

Maybe cause of UHS card? Will try to find 8 and 32 Gb simple cards...
[G4 Android Development] culot:
There is a bit in the LK/aboot that can choose SD instead. It also could be deeper in the boot chain, in the Qualcomm SBL* maybe. It is definitely a feature, though unsure where it lives.
[G4 Android Development] Pterka:
Well, OK, It's perfect that there is such bit but in "manual" - we don't edit any bits... we just imaging SD card and put it in the phone. Autoshifting?

Still tries to find SDcards...
