LG G4 half-bricked / full unusable

Hi everybody !
I usually (always normally) succeed myself at resolve my phone problems, but this time I can't do anything.
My problem :
I have a LG G4 ; I saw an update of Imperium Rom (v8) this morning, so I installed it, everything worked well until I decided to install a, apparently, ****ed mod on xposed ; and since I have rebooted I can't do anything ; the LG logo shows and just after "UI system as stopped", just one time but, then I can't do anything, screens over screens, can't access parameters, password required, "flex mode" (never saw this before), re-password, system UI restart, loading background, restart system UI; and this in a infinite loop SOOOOO
I decided to reset it, yeah... But I can't access my recovery, wow o/
I followed the step to access it by switch it off and press volume down etc --> It just boot normally, or best in safe mode by magic but same problem ; via parameters but I can't access parameters ; and via ADB buuut my phone isn't recognized even with the complete sdk, drivers, everything you want, there's nothing to do because --> while restarting system UI it deconnects so of course it can be recognized
I removed xposed (while I could still access recovery, as I was thinking it was coming from the xposed module) and so now I can't even access recovery via shutdown menu (as I had put "reboot to recovery" in via Xblast, a xposed module) ; and of course it doesn't change anything
I neeeeed your help so much, I don't mind losing what's on it :crying:

Please ensure you REALLY use the correct key combo! Just saying bla does not tell us what exactly you tried.
If you really can't get in you can try to Boot into download mode

Then use lgup to reinstall stock ROM and do all the stuff again to get twrp, root and a custom ROM.

Thank for your answer ! No it couldn't even boot in download mode
I resolved my problem by forcing again the buttons to reset completely, it finally showed me after about 30 boots or more the reset screen, I said "ok" ; and in fact it just rebooted saying "updating Android", I did not lost anything.
I still don't understand how it happened but anyway !
I don't know if it's possible to set the topic as resolved ? I don't find it

wipe data problem

Hi my Max 3 has gone into MI-Recovery 3.0 mode
The options are (a) reboot - when I click on this it brings up a picture of Miui 10 in background with some chinese options about entering wifi passwords?
(b) wipe data - when I click on this it takes me to 'wipe all data', I click again and it asks me to confirm 'wipe all data', it then gets to about 3% on a spacebar and says 'data wiped successfully', and then takes me back to main menu again
(c) connect with mi assistant - asks me to plug phone in using USB then doesn't seem to recognise it
Any body any ideas please on how to reboot my Max 3?
Thank you

Unfortunately your phone is in EDL mode (download mode). Only an authorized Xiaomi account can recover it.
This is due to ARB which is active in Mi Max 3 and other Xiaomis. If you try to go back to the Android or Rom version (in some cases), this will start.

Mi A2 Lite Bluetooth Audio Problems? Back To Oreo?

Hi There,
Just bought my GF a Mi A2 Lite a few weeks ago and she is loving it compared to her old iPhone 5s but one major issue atm is that her bluetooth headphones seem to be giving her issues!
The audio stutters a LOT even when right next to the phone. Tried resetting the Bluetooth connection but to no avail.
I had a quick scan through the forums and seen that people recommend going back to Oreo to solve the issues.
Is there any clear guides or links on how to do this? I know my way around tech so should have any issues following a guide.
Thanks in advance!

Yes, it's a very annoying bug.... I have it too, but didn't find a solution
That's the reason why I downgraded to Oreo!
If you want to downgrade,
1. you must unlock the bootloader, but this will erase all of your data. So, don't forget to make a backup of your internal storage. https://forum.xda-developers.com/mi-a2-lite/how-to/guide-how-to-unlock-bootloader-official-t3885578
2. Install MiFlash and ADB on your computer: https://www.xiaomiflash.com/download/ https://forum.xda-developers.com/showthread.php?t=2317790
3. Download an oreo stock rom and unzip it: https://forum.xda-developers.com/mi-a2-lite/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824871
4. Boot your phone into bootloader
-> Connect your phone with your computer and enable ADB in developer settings
-> Shutdown your phone and hold Volume Down and Power-Button to boot your phone into fastboot/bootloader
5. Open the MiFlash-Tool on your computer and select the Oreo-Stock-Rom which you want to install.
6. At the bottom of the MiFlash window you must choose clean all, this will erase all of your data!
7. If your phone gets recognized from your computer and the programm, then you can hit the button flash on the top of the window
8. This procedure takes a while, so be patient.
9. If everything works, it will reboot your phone automatically.
10. Maybe you will have the bug of swapped SIMs. You must install TWRP: https://forum.xda-developers.com/mi-a2-lite/development/official-twrp-daisy-t3855396
and flash this file to fix it: https://forum.xda-developers.com/attachment.php?attachmentid=4704476&stc=1&d=1550012435
11. Perfect! You downgraded to Oreo!
I hope this little guide could help you, and sorry if it's a bit complicated

If it's any consolation, I had this issue on Oreo and Pie!
I'm now upgrading to a Pixel 3a, but keeping this phone for development. Might try porting Ubuntu Touch some time. ?

Okay, that's weird ?
Maybe there was a problem with your Bluetooth headset?

If so, it was a problem with every one I tried!
I tried on a generic Bluetooth speaker, two different generations of Echo Dot, and on a current gen regular Echo.

It is channels problem. Bluetooth and WiFi are on 2.4GHz. Some frequencies are busy and it stutters. Turn off WiFi and Bluetooth. Turn Bluetooth on and connect your Bluetooth device. Wait 10 seconds and turn on WiFi. After this WiFi will avoid frequency where is Bluetooth device and use free frequencies.

Interesting... sounds like a pain in the ass, but I'll try this next time I get chance.
Thanks!

But it stutters also when wifi is offline. And on Android 8 I don't have this frequency-problem

You can solve by adding the the missing codecs, all the routes are still there, xiaomi removed licensed codecs

Downgrade helped as of 30.05.2019
Mi A2 lite
Bought Galaxy Buds. Stuttered and eventually lost connection.
NOTE:What comes ahead is my personal experience (with some software errors that doesnt seem to have effect on our goal) downgrading my MI A2 lite to Oreo.
Downloaded Android Oreo 9.6.11 , ADB and Fastboot, Miflash(latest from site) from links in the beginning of the thread.
Very few proper video tutorials (Indian mostlyXD).
Enabled developer options on my phone (tapping 7 times on build number). In developer options enabled allow OEM unlock and turned on usb debug mode.
Turned off phone and launched it it fastboot mode (hold "volume down" and power button simultaneously). Connect phone to PC via usb.
Open folder on PC where you installed ADB and fastboot software. Launch cmd.exe or smth. In black window type "fastboot oem unlock" Enter. The phone reboots (takes a lot of time dont be alert) and wipes data from your phone. You will see a scary message/warning (disappear s after few sec) that asks you to lock bootloader back.
NOTE: somehow my device did not ask for any confirmations for enabling unlocked bootloader.
NOTE 2: I was trying to do this whole process by video and text guides. Some ppl type commands in cmd "fastboot flashing unlock" and then "fastboot flashing unlock_critical" BUT for some reason this commands did nothing. So all I did is oem unlock command.
After OEM unlock command rebooted phone skip all phone setups and open developer mode again (if it is locked) and in dev options check if "allow oem unlock" and usb debug mode is turned on. Turn off your phone and load it in fastboot mode (volume down+power).
On PC unpack Android Oreo files. It should look like a long name folder with some .bat files and folder (avoid unpacking in place with strange name paths).
Launch MiFlash tool. NOTE: it gave me a prompt for installing drivers and after i pressed it gave an error. It is fixed by creating inside MiFlash tool folder a new folder and naming it "log". Then launch the tool again and press install drivers.
Once you are in MiFlash program there is a ling space where you can insert a file path. You need to copy a file path that leads to your unpacked Android Oreo files (the path should lead inside where the .bat files located). Paste this copied path into MiFlash path bar and press refresh button. If there is no error you can proceed by pressing in the bottom right corner a "clear all" option and in the top right "flash" button. This will install Android Oreo on your mi a2 lite.
After the process is done i had an error in MiFlash program BUT the phone reboots on its own with downgraded Android version. Turn the phone off, load it in fastboot mode, connect via usb and run in ADB folder CMD.exe and run "fastboot oem lock" command. The phone reboots, takes a while.
!!!
After it reboots immediately skip all phone setup menus especially wifi and account options and go straight in settings to unlock developer mode. In developer options TURN OFF AUTOMATIC SYSTEM UPDATES! After it you can finish phone setup process ,accounts, networks and everything else.
An Android message "update available" can pop up. To get rid of it for good simply swipe it slowly A BIT (not all the way) till you see a cog sign (options icon) and there turn of this notification.
Now you can go smoke a cigar. Android 8.1.0 Oreo installed AND it wont update automaticlly to PIE. You can use your bluetooth devices properly (or whatever problems you had).
Have a nice day. Gonna probably go buy Samsung A30. This **** is unacceptable. Pie update rolled out long time ago (Android Q is releasing in 3 months from now) and this stuff is still not fixed. Wtf

Solution
I did a simple step to fix pair
Reboot into safe mode, pair the select device, after pair reboot out the safe mode and you see the device paired.

I installed bliss os and it won't boot!

Hello guys, i installed multiply times bliss os on my pc, after finishing the installation when i go run bliss os, it boot up, but after a restart it says: "insert boot media in selected device and press a key"
My bios does supports uefi and i tried everything but always the same, where is the problem?

Disable secure boot
dejanr96; I'm new here, but I think you should go into the bios of your computer and find the option to disable "SECURE BOOT". It could be located under a tab called "authentication" (or something like that).
Another thing you can do is find a setting in your bios called "LAUNCH CSM" (or something like that). "CSM" stands for "Compatibility Support Module".
Hopefully that helps.
EDIT: I think you need to apply both the settings I mentioned together. First you disable "Secure Boot", then that allows you to enable "Launch CSM".

You can use grub2win to make it bootable
Mod edit: Random YT link removed.

Hello everyone. I'm having trouble running BlissOS on Surface Pro 3.
I've installed it several ways and it still won't boot. Automatic install mode didn't work either. After installation, I press the system to start but the system does not start and goes to the bios. I will check if any of the older versions will work. Are android to pc sleep issues a common problem?
I am writing through a translator. Sorry if something is unclear.

Motorola One Action auto update failed now stuck on "Just a sec..."

Hi,
My Motorola One Action is original (so no custom firmware or rooted) and every now and then i receive auto updates. Recently the phone was upgraded to Android 11. Fine.
Last weekend there was an update and in the morning the phone was stuck on Android bootloader with the question "format" or "retry" (cannot remember exactly, but it was 2 questions) and i chose "retry". The device rebooted; android logo showed up and then the google/android assistant showed up with the notification "Hello" and a lanuage selector.
I choose NL or EN and then a white screen with "Just a sec..." appears and this screen will stay there forever. I put the phone on charger and waited 30 hours, still the same.
What i tried:
- reboot;
- press & hold power button long time; reboot;
- turn off and then volume Down + Power key bootloader. There isnt much i can do here;
- from screen above; go to fastboot mode (volume Up + power) but unfortunately there is no whipe cache option; only whipe data / factory reset.
FYI: there are still a lot of photo's on the device; i dont want a factory reset and/or whipe data.
I put device in bootloader mode again, connect with usb and installed "Rescue and Smart Assistant". The device recognized, IMEI is found and more stuff. In this Windows app i can download the correct firmware; i store it in c:/motorola/firware. The file is troika_reteu_rsbs31.q1-48-36-23-2_subsidy-default_regulatory-default_cfc.xml.zip
The the "Start Rescue" button is shown; but the message "Flashing removes all data from device".
I dont want that so i followed this guide:
The conversion went OK and executed the file generated (.bat), immediately a upload process starts; this takes about 5-6 minutes. After that; a device reboot and still... the same result.
Any tips or advice would be very helpful (i hope).

I found this; looks promising

But unfortunately the image browser does not respond.

I have contacted Motorola / Lenovo using their forum. In short their answer is that for almost sure the only way is to completely reset the device that means whiping data.
Is there absolutely no way to access the data partition?

I used ADB to flash a newer and older version of android.
Both version gave a error message directly when phone powered on.
Then i re-installed the current version of android; phone worked again. Unfortunately all data lost.
