I'm trying to revive an old stock v20 with random reboot issues but I can't access download mode because the physical up volume button is broken.
The bootloader is unlocked and it is on software version 10k. I have access to ADB and fastboot - both working.
Is there a way to enter download mode with this disability or is there another way for me to upgrade the software to 10p, then 20h?

or as I assume:
Code:
adb reboot bootloader
I don't have this model.
Thanks for the quick reply. ADB reboot bootloader works for fastboot but not for download mode.
I was able to get the phone to reboot into download mode using Uppercut (LGUP did not work) and selecting upgrade with the 10p kdz. Once the install is finished I should be able to continue on with Lafsploit. I will report back with the results.
[SOLVED]
Okay so here is the workaround for this:
Use Uppercut to reboot the phone in download mode and unplug the cable just after the phone restarts. Now you have access to download mode and can connect the phone to another PC running FWEL for Lafsploit. After this you can boot into TWRP and flash normally

Hey guys, I've been trying to unlock my bootloader so that I can try and root my Maven 3 via Magisk. The problem is, I can't get into the bootloader. If I try to reboot to the bootloader from recovery mode, it just restarts like normal. Same thing when I try using adb commands in the cmd prompt. I am on Windows 7.
I think it could be unlocked trought EDL mode. But we need some expert help
I unlocked my phone with at&t but I think it only unlocked the SIM.
I enabled usb debugging and oem unlock, but when I issue the command (in ubuntu term)
adb reboot bootloader

is just boots into the android system.
Any clue on what to do?
I have the same question - bootloader mode will not load when I issue "adb reboot bootloader", nor will it go into bootloader when I go into recovery mode (via POWER + VOLUME UP) and then I choose the "Bootloader" option. The phone just boots into the system. When I use "adb reboot recovery" it does go into recovery mode, and I am able to get a shell and copy files via adb just fine. I am using the latest platform-tools.
This is a ZTE Z835 (Maven 3), AT&T, carrier unlocked phone.
I don't think there is a bootloader... I have not found any fastboot-compatible mode on this device nor have I heard anyone else find one. You have FTM mode (Power + Volume Down) and EDL mode (adb reboot edl). EDL mode lets it work with QFIL, and with QFIL, you can literally dump and modify any partition on the device you want... I'm not sure what else you want. There's a new method for unlocking the bootloader https://www.xda-developers.com/unlock-bootloader-zte-phones/. I found that my devinfo partition was already unlocked, but you may need to check. I'm going to try and figure out how to create a recovery.bin partition able to be flashed in QFIL.
LG V20 910
On boot, it shows the LG logo, but does not start.
When I hold Vol up and plug in usb, the same thing happens
When I hold Vol down and plug in usb it does boot to fastboot
Factory reset gives a kernel crash error
adb does not recognize the device
fastboot via command prompt in windows does recognize it
LGUP does not recognize it
Is there a way for me to flash back to H91510e_00_VTR_CA_OP_1205.kdz with Fastboot, or is there another method to get download mode again?
How did you brick your phone? If you just turned it on one day and this happened, it is more than likely a hardware problem.
Since you say that you can get to fastboot -- I am guessing you were rooted since the H910 doesn't have fastboot without the engineering bootloader.
If so, then fastboot boot twrp.img
If TWRP will boot, you can fix your phone from that.

The good news is that you've got the dirtysanta bootloader installed (that's why it's reporting us996) so you should be able to fix it without using LG UP and having to redo most of the process.
Install twrp by doing fastboot flash path/to/twrp.img .then pull the battery when done. Then enter twrp by using to volume key method (hold volume down, press power until the screen turns on, then tap power repeatedly until a menu asking to factory reset appears, say yes (while twrp is installed it won't actually wipe anything).)
Flash a rom (a stock one is here), and magisk.
If you can't use an sdcard to get them accessible to the phone in twrp, in twrp you can go into advanced then sideload and connect to a PC and do adb sideload path/to/rom-or-magisk.zip

to totally back out and bring your phone to totally stock use download mode (from powered off hold volume UP while connecting to the pc). The screen will be still messed up but it will still work on the pc.
Use patched LG UP in partition dl mode to flash everything with a stock h990(ds) kdz.
Once you start using dirtysanta next time (if you decide to try again) be very very careful when using LG UP (easier to just use stock flashabile zip) unless you want to redo the above and flash EVERYTHING back to stock (if you ever flash the aboot partition in LG UP and anything ISN'T stock it will brick you! This mostly applies to partition dl mode since upgrade mode flashes everything, but partition dl mode is the only mode you can even potentially flash things and keep root (but I don't encourage this... its easier and saferto just use zips in TWRP to flash firmware (mostly stock basedrom or so called stock flashible zips tend to also flash all of the firmware except parts needed to keep root. )

But did you use partition dl mode? It alone bypasses the model checks.
Partition dl mode isn't in regular lg up, you need the special patched version I linked (replace the files of your regular lg up with the special version)

Try uppercut then. Use upgrade mode if it works but partition dl mode is missing. Note uppercut asks for lg up version 1.14 . I can't remember what version the patched one is but you may have to reinstall that version instead.
I got a LG V20 H910 model and I cannot reboot the phone into the fastboot mode to get the device ID. I tried to do this on Windows and Linux and everytime I enter the adb reboot bootloader command, it will just reboot the phone but not into fastboot mode. I even tried to turn the phone off and tried booting it up by holding the power button + volume up and power button + volume down and it will still boot up normally.
Any help will be most appreciated.
follow the h910 root instructions, the bootloader doesn't actually get unlocked, instead the bootloader is replaced with a developer bootloader ** do a backup dump using LGUP even though the instructions say you don't have to!!(I ruined a phone by not)..... check antirollback too

Hello,
I guess I ****ed up big time.
My G6 is currently in the state of rebooting over and over again. Can't access EDL Mode through volume up.
I only manage to get to factory data reset, but it does not change anything.
My mess up:
I unlocked the bootloader with this guide just fine: https://forum.xda-developers.com/t/...urrently-supported-eu-h870-usa-us997.3614719/
Until step 9 everything was fine.
But using the factory reset trick to enter the TWRP 3.5.1 it just didnt work. The phone would boot into normal android.
I then rechecked the LG Unlock guide.
The command "fastboot flash boot boot.img" seemed familar.
Not realizing the difference between recovery and boot I used the command above to flash TWRP.
Now the phone only reboots. No chance to enter EDL mode (I see it poping up for a split second, then the phone switches to a normal boot).
No chance to boot into android to use adb commands.
I guess my only option is to try to open up the phone, shorting two points and use the following post to get into edl mode?
LG G6 TestPoints for EDL Mode (9008)
Simple af. Just short them. For incase that doesn't work;
forum.xda-developers.com
Or is there any possibility to recover it through the "factory data reset" menu?
Big thanks to anyone ready to provide some support!
EDIT: Nvm, sorry for "spam".
After trying over and over again I could get the phone into EDL mode. I then could fix the phone via LG Bridge. Will try my previous steps again with a older TWRP version (this seems to be the solution to my first problem)
