Hi all -

My trusty G4 took a dump, so I got a replacement. It's on MM 2AA, so trying to use this method to downgrade back to LP. However, computer (booted up Winblows 10 to do this, wish I could do it in Linux ;) ) won't see the phone ("no handset connected"). Tried this:

multiple times, but no joy. Any other ideas?

Also, if I do get it to work, can I use it to flash the rooted 13b system image directly (I think I did this the last time, about a year ago, with another replacement G4, but not sure) or do I have to flash the KDZ only with this, then do the "low effort root" method?

Thanks!
[G4 Q&A, Help & Troubleshooting] dilligaf56:
Answering my own questions:

Have to go into USB mode. After that, LGUP sees the phone just fine.

Have to flash the KDZ. Trying to flash the rooted system.img fails. KDZ flashed fine, then did the "low-effort root" method again - no problem, nice and slick, new phone is rooted.

To downgrade from 2AA, you must get the new 8994.dll file (see post from WAIDroid).

Hope this helps anyone else.

Upgrade from Lollipop 10b to Marshmallow 21y directly?

Hello.

The first post is very old now and I read some of the last pages in here but still not sure about this...

I have an H810 (AT&T version) with Lollipop 10b and I am wondering if I can update it using LGUP with the 8974.dll and Marshmallow 21y KDZ found here:

storagecow.eu slash index.php?dir=Xda%2FLG+G4%2FH810%2FAT%26T%2F

Anyone tried this?

Thanks a lot!!!
[G4 Q&A, Help & Troubleshooting] sdembiske:
While I don't consider LG Flash Tool 2014 to be necessarily the best or safest alternative to upgrading or downgrading stock kdz's (my reference go-to is LGUP-NEW, a generally safer method IMO), I recently ran into a situation where having LG Flash Tool 2014 in the arsenal proved invaluable. I softbricked my rooted H812 with some build.prop modifications and was unable to get the phone recognized with LGUP-NEW (yes, LG mobile drivers were installed, etc., etc), or any thing else for that matter to reinstall a stock kdz. I was almost ready to send it back to the carrier for repair but decided in a last ditch effort to give the LG Flash Tool 2014 a try and flash a known, proven stock kdz I had used a few times before with LGUP-NEW. While the phone wasn't recognized per se, the LG Flash Tool 2014 worked flawlessly to get me rolling again.

I wanted to let other members know to give it a shot when all else seems to not work, provided they have a known proven kdz on hand.

Hi! I'm sorry if this is a noob question, I am one: I have a refurbished H815 which might have a different variant motherboard.

[G4 Q&A, Help & Troubleshooting] sdembiske:
You could check out this link and use a Hex editor (WinHex) to modify the H815 kdz/tot to reflect H811 model (if I understand correctly that your model is in fact an H811), if you haven't tried it yet. https://xdaforums.com/g4/general/howto-flash-models-tot-file-avoid-tot-t3282938

I havent checked if i can downgrade or not. I had installed 7.0 from TWRP because there is no KDZ file as far as i know for 815. Had major heating problems and thought of downgrading to 6.0. Tried with LGUP but keep getting errors. Now the phone boots only to download mode. I cant make it boot to recovery.

Hello, im having a lot of issues trying to flash a friends g4. Has no idea what he did to it. all i know is it now says bootloader is unlocked and it freezes at the tmobile logo. I have tried relentlessly to flash it with lgflashtool using the h811 kdz in the op. But i keep getting the server error and i let it sit there for over 30 min multiple times, waiting does nothing. i am trying to use lgup but i have no idea how to get the tot for this phone i have searched high and low iv tried extracting the kdz to get the dll and the dz but no tot. can anyone point me in the right direction or is this just dead because there are no tot files to tmo g4.

Don't select refurbish, but the second option at first. It will let you choose a kdz.

Then close LGUp and restart it again. Your kdz will still be selected and then you can choose refurbish.

[G4 Q&A, Help & Troubleshooting] sdembiske:
You could try Uppercut: https://xdaforums.com/lg-g5/development/uppercut-lgup-loader-g5-variants-t3511295

Or, failing that, you will have to search for the correct dll file for your phone model/kdz version and plug it in - there are guides in some posts on how to do it - just do a thorough search on XDA first, then Google it.

Last resort: You could use LG Flash Tool 2014 (https://xdaforums.com/showthread.php?t=2797190) but I would suggest that if you are trying a stock kdz that you have not used and verified beforehand, you run the risk of bricking your phone. The safer bet is using LGUP-NEW with the correct dll.

Hello! I resurrected a device from hard bricking, but now I have the device recognized as "Mediatek USB Port (COM4)". I installed correct versions of Mediatek VCOM drivers, also for 64bit (I have Windows 10 64bit).

The Device Manager shows it's Hardware Identifier as 0E8D:0003.

I understand 0003 is for generic MTK devices or with software errors.

The chipset of my recovered device is mt67xx.

Cannot complete flash! LG G2 D800

Every time I try to flash a TOT, it gets to around 15% and my phone shuts off, then goes to black screen/9006 qhsusb status. I then use SRK Tool to unbrick and try flashing again but nothing changes. Same result every time. Also same with 2 different versions of LGFlashTool. Have repeated this process probably 100 times now with each of the three D800 TOTs provided here in user hyelton's thread: https://xdaforums.com/showthread.php?t=2432476. It seems nothing will work.
