Hello.

I have an H810 (AT&T version without SIM card since I live outside USA) with Lollipop 10b and I am wondering if I can update it directly 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?

Seems easier, faster and the Marshmallow version is newer from the OTA file in here...

Thanks a lot!!!

Completo novato

Hola, soy completamente nuevo aquí y tengo unas cuantas dudillas al respecto. Quizá la más tonta: supongo que los comandos esos se corren en Linux, verdad? :eek: Luego, en mi caso el teléfono está liberado y tengo sim de Telcel, ¿me basta con quitársela para poder hacer la actualización? :confused: Y, bueno, la verdad es que nunca había hecho algo así y hasta hace unas horas me enteré de todas esas cosas sobre Roms y versiones, así que ¿eventualmente puedo actualizarlo hasta la versión 22c si me llega al teléfono o ya se queda en esa mientras no le haga más cambios? Por último: ¿es posible (y sería conveniente) actualizarlo a una de las versiones internacionales H815? Gracias, y una disculpa por tanta ignorancia :P

Technical problems

I have an idea for the problems with the android version 6.0 V21Y, can someone change the version-number of the 5.1. Version, so that LGUP thinks thats a higher version and we can go back to a working version. I think the "V10o" would be the best. My opinion is, that this step could not be so difficult.

Hello,

Thank you for your time into this.

I flashed my LG G4 H81010o as the link describes. Everything went well.

Then I did the steps you have given and when executing the last command the phone screen flashes once quickly and does nothing while the PowerShell in Windows 10 says:

Starting: Intent { cmp=com.lge.lgfota.permission/.DmcEzUpdateStart }

Meanwhile, nothing happens on the phone. The phone is connected with wifi and the desktop also has an internet connection.

Can anyone help me with this?

[Fire TV Q&A, Help & Troubleshooting] JedSpink:
Hi all

Sorry if this is a repeat but hope not.

My AFTV updated to 5.0.5. Claims an installed date of 21 Jan 16, but only recently have I noticed a number of issues, so not sure why they took so long to show up, unless 21 Jan is actually the 5.0.5 build date, rather than install. So here's what I've found (on Fire TV and stick - got both).

1. First Llama stopped working - I used LLama events with Condition/Action setup to start Kodi whenever I started Ikono (and switched logos). Testing the condition appeared to work, i.e. Kodi fired up but the difference was that in the test BEFORE you used to see Ikono fire up for a few seconds then switch to Kodi. After the 5.0.5 the test just fired up Kodi. And then when you start Ikono in the normal way, Kodi does not fire. Same for all my other "shortcuts".

2. Wukong: would not work for a while, the mouse pointer showed up by clicks did not fire off any action on AFTV side. A few reboots and messing around solved it but even now a bit flakey, compared to solid before.

3. Side-loading: cannot side-load apps now! Can connect via ADB, but running "adb install xxxxxx.apk" results in a:

error: device not found

- waiting for device -

4. Apps that update themselves, e.g. ShowBox, are failing (probably for the same reason as 3)

So is this common? I'm assuming Amazon have put in a range of changes to lock-down the device? Are there any workarounds / fixes?

Jed
[Fire TV Q&A, Help & Troubleshooting] bula1ca:
1) Lama does not work under OS5

2) Sometimes I have to reboot as well

3) go in settings/ Developer Options/and turn off and on ADB debugging a three times ....
[Fire TV Q&A, Help & Troubleshooting] JedSpink:
Thanks for confirming 1), I tried AutomateIt too and it seems to have the same problem, so I suppose it's some sort of OS-level blocking of the kind of hooks that Llama and others used in the past? Guess they could argue it was a security improvement as allowing one app to start another could be abused...

Re: Wukong and side-loading being blocked.... I played a bit more and similar results to you.... I don't think the OS is deliberately blocking / preventing but there may be a bug or issue. For example if I do a reboot of the box then, say, Wukong, will work fine but then tried:

adb kill-server

adb start-server

adb connect xx.xx..x.xx

and then quick test with: adb shell

and get the error: device not ready.

Do a reboot, don't connect Wukong and try the above commands and adb shell works (quick test) and then any commands like adb push / install work too. But then Wukong seems blocked, e.g. may connect as mouse pointer but using the click function does nothing, or may not connect at all.

I'll try your fix of the ADB debug off/on instead of reboot; and see how that goes.

Fun times! :)

[Fire TV Q&A, Help & Troubleshooting] El_Nino9:
did you carry on using your device as is with the same data from the old version?i.e. no factory reset after the update?

i ask because things often break after an OTA.

i factory reset my fire stick after the update and then again after kingroot(do not push super su on it yet if you want root-wait for a pre-rooted image if you want super su).

so after re-logging in, i enabled adb, sent kodi to the device and i can launch it from Apps on the left hand side, no need to go into settings anymore or even use llama. it's there. it won't be in the recent apps, i don't know why, but at least it shows up in apps.

i don't use wukong, but i have set up my rooted phone to be a bluetooth mouse, just encase or even use my ps4 touchpad.
[Fire TV Q&A, Help & Troubleshooting] bula1ca:
Lama is broken in OS5. Are you sure about it?
[Fire TV Q&A, Help & Troubleshooting] El_Nino9:
i never said llama works under OS5.

all i said it's not needed anymore due to kodi being available to launch from the apps menu on the left hand side.

My remote mouse for fire tv works fine on OS5 prerooted rom
[Fire TV Q&A, Help & Troubleshooting] JedSpink:
Hi that's what I get sometimes, shows mouse pointer but click does not work. I find a reboot of the fire box fixes... what i've noticed it that once you have got say Wukong working then adb will not do adb - install or push: gets the device not ready error. Again a reboot will fix but then, say, Wukong won't work properly.

So it seems like something is blocking the other process - hence why I was wondering if a bug.

Take on the point about doing a factory reset from [MENTION=2187187]El_Nino9[/MENTION] but then I'll have to reinstall and setup Kodi and my other side-loaded apps from scratch?

Jed
[Fire TV Q&A, Help & Troubleshooting] El_Nino9:
as with all factory resets, you have to redo the setup. there are tools available to back up your setups and its easy enough to adb install apps. plus you might be able to push all the latest versions of the apps back on the fire if you haven't done so already.

it depends what you want to achieve and what you want to eliminate. it all involves doing some sort of work, however i understand the more little work you have to do the better it is. no need.
[Fire TV Q&A, Help & Troubleshooting] JedSpink:
You are right of course. :) Just being a bit lazy. It's mainly Kodi I worry about as I have a lots of add-ons and takes time to setup correctly. I know you can backup your Kodi configuration but never done a backup / restore of Kodi. Will take a look into it and if I can preserve my add-ons then will do factory reset and adb -install them again.
[Fire TV Q&A, Help & Troubleshooting] El_Nino9:
i rooted my device and would use titanium back up. however kodi within itself has various tools.

they have an addon called back up and they also have other features.

however, on the stick, you can use storage easily unless you know how to adb well.

for simple use i would recommend titanium back up and then back up to a cloud service such as gdrive.

each user has different preferences.

if you aren't rooted just use the addon back up too or there is a 3rd party app that also does similar stuff which i've never used so can't help.

if you do decide to root, do not use supersume app after kingroot. stick to king root su until a rooted system image is released for the device. i used kingroot 4.1 from xda thread and despite it saying failed i had root.

if you're not comfortable don't do it

Device: LG-D325

I tried rooting, unlocking bootloader, and installing custom rom (this link).

I successfully gained root & unlocked bootloader. Than it all went down.

I flashed recovery and booted into it, using "fastboot boot recovery.img" command.

I flashed cm12.1 and after that I got the "purple screen" error.

When phone is off and I try to normally turn it on:

1st screen:

Secure booting error!
Cause: boot certification verify

2nd screen:

DemiGod Crash Handler : DBI Err Fatal!
Board Rev.: 1.0
Ram dump mode.
Option : SD card ram dump mode.
Push below files to sd card before test.
rdcookie.txt, rtcookie.txt
Please do following action.
1) Ram dump Mode. Please connect USB.
2) Get the ram dump image using QPST Configuration.
3) If sdcard ram dump enabled just wait for reboot.
4) Collect ramdump files from your pc or sdcard.
5) Send e-mail to W5-BSP-Global@lge.com

The same happens when I plug in the USB cable when phone shut off.

Also, I cannot enter the fastboot menu (previously I could - before flashing CM12.1 via recovery) using volume UP + power buttons. Therefore, I cannot enter recovery.

Any info on this situation?

The test point method is not the JTAG method

Use the test point method. It works very well and it's quite easy. But first I recommend you try "LG Flash Tool 2014" . If that works, no need to open up the phone for test point method. If you are already seeing pink screen demigod error DBI fatal error, no need to go for JTAG I think.
