Uninstalled wrong app, LG K61 stucks in boot - Android Q&A, Help & Troubleshooting

I have uninstalled with adb the google package manager on my device, now it does not boot up. Does anybody has an idea to bring it back?
P.s: In developer options I have unlocked usb debudding and oem unlock. I can not find the fastboot mode.

Reflash Stock ROM.
FYI:
Fastboot is merely an executable you can operate on device's bootloader once it got unlocked.

I have found this tutorial, is it right? There are also the firmware files I need on this side.

Thank you very much, I have managed it!
I did it with the great lgup utility and the firmware you can get you can find here (for my
LG Q630EAW).

LG V10 H960A Root (Require Clarification)

Hello,
I recently purchased the H960A model (European Version). I've read several threads about rooting this phone, but I want to be absolutely certain I'm following the proper procedure.
1) Do I need to unlock the bootloader prior to rooting? My understanding is that this model recently had the bootloader unlocked by LG Developer.
2) Once I've followed the instructions to unlock the bootloader, I'm assuming I need to go into the developer options of my V10 and enable "Enable OEM unlock" and "USB debugging"?
3) Once I've done the above two items (if all of that is necessary), what next? Can someone direct me to the correct process for root?
I was hoping to add TWRP but it seems that there is only an unofficial process currently.
Any help on accomplishing root (safely) with this phone would be greatly appreciated. Just want to be certain I'm following the proper steps so I don't brick my beautiful new international V10.
Thanks
You need to enable usb debugging and OEM unlock before unlocking the bootloader then flashing twrp unofficial then flashing supersu file
Hi,
yes, you need to unlock the bootloader before you can root your phone. Please be aware that this will also initiate a factory reset of the phone, so if you have already a lot of apps installed and data on the internal SD card be sure to make a backup. For the apps you can use LG Backup. You need to have an external SD card and be sure to select this as destination for the backup. Otherwise it will be deleted during the factory reset (if it is on the internal memory; that gets deleted as well).
Then just follow the description on the LG developer page step by step and then the TWRP thread to get root. As vip57 already pointed out you need to set USB debug and OEM unlock before trying to unlock the bootloader but that is also described in detail on the LG developer page (step 7 and 8).
Thanks to all who responded. I unlocked the bootloader successfully. Then installed TWRP, rooted, and installed XPosed. All went perfectly, no problems or glitches. LOVE MY V10!!!
More clarification please
Hi, I need more clarification, not the OP, though.
I read some of the guides explaining how to root this phone. Thanks for the info regarding the bootloader, I didn't know that. I also don't know what this TWRP is.
I want the stock LG ROM, I just want the root, is this possible? I want the standard camera, galery, capture+, all the standard LG things. I also want the standard updates, so I want to get a
system update via LG bridge, when my friend (unrooted phone) gets one.
Is this possible, or do I have to install an unofficial "kinda like the stock" ROM, to get root access?
Thanks in advance!
Hi everyone ;
I have a problem to reboot in bootloader mode ; LG USB drivers are installed ; debug mode and OEM unlock are ON ; H960A still with original firmware (5.1)
When I type 'adb devices', my phone is listed.
When I type 'adb reboot bootloader' the phone reboots, but in android, not in a fastboot mode
when I turn the phone OFF, press Volume Down and attach a USB cable from PC : it reboots to android
when I turn the phone OFF, press Volume Up and attach a USB cable from PC : it reboots to some download mode (firmware upgrade, don't disconnect the cable....). I have to remove battery as it's unresponsive then.
Any idea to help me ?
thank you
edit : it was simply not possible to access the bootloader from android 5.1.
I updated to android 6 (with LG Bridge), and then 'adb reboot bootloader' rebooted in bootloader mode.

bricked :(

Hi! I just bought a Honor 9 STF-AL00, build: STF-AL00C00B201.
As it is the chinese version, I wanted to rebrand it, so I follow the instructions on https://forum.xda-developers.com/honor-9/how-to/guide-honor-9-t3653719.
Unlocking bootloader was successful and as chinese firmware, it did not had a FRP lock.
The first time, rebranding stopped just before the menu.
The second time, I could access the menu and did the install.
But it looks like it did not go as expected because when the phone booted, it did not load TWRP but eRecovery.
So I booted in fastboot, it says phone locked & FRP locked.
I booted once again in eRecovery to download package from server and recovery but it says getting package info failed.
I tried to install stockrom from sd but it didnot work out.
I still have the bootloader code, but now i cant even install TWRP.
Can anyone please help me?
It is a brand new phone, I even havent use it yet and it's already bricked :'(
I install an service full repair stock via dload
http://androidhost.ru/v5
it is working right now.

You can always re-unlock your phones bootloader again, the key is always same, then flash or boot twrp with fastboot.
Some developers says the command for oreo is: fastboot flash recovery_ramdisk [file name] but I used this: fastboot flash recovery_ramdisk_a [file name]
You even can try to just boot twrp without flashing it to your recovery by simple typing: fastboot boot [file name]
If fastboot can flash twrp, turn your phone off then hold volume up/+ and power button same time and hold them until the state of unlocked warning appears.
You can use dload method or you can use HuRupdater method to flash firmware. You'll find introduction for how to do it.
Just search on xda

Xiaomi Mi9T/K20 Hard brick recover tutorial

Hello to everybody.
Dear friends I post this to guide (only unlocked bootloader rooted phones) you through the steps that I used to succesfully recover my Xiaomi M9T
from a hard brick (by that time only edl mode was available).
Since Xiaomi has decided to lock down their Mi flash tool, and only special authorized accounts have an access to their utility tool.
was almost impossible (by yourself) to recover your phone from a hard brick situation.
I found a way arround to xiaomi tool with a 100% succesfull 1st atempt with my own phone it worked flawlessly.
Forget the point to point jumbers with a required open phone procedure.
Forget the authorized account holders with a teamviewer use of your computer and a fee for their services (logical).
Forget returning back your phone to any authorized repair center for a revival for what ever cost.
Below you will find al the steps one by one.
First thing you need is to install: minimal_adb_fastboot_v1.4.3_setup. https://forum.xda-developers.com/showthread.php?t=2317790.
Run it and put "Y" and hit enter all the way through.
Second you need to install: TOOL_ALL_IN_ONE_2.0.1.1. https://forum.xda-developers.com/android/software/tool-tool-one-driversunlocktwrpfactory-t3358711

Press tab advance options.
under the advance options window press first the tab Set ADB and fastboot privileges system wide.
It will asc you for confirmation press the tab again with the same Set ADB and fastboot privileges system wide.
Then press the tab Open a free terminal with ADB and fastboot privileges.
and type in the terminal the cmd fastboot oem edl,
It will say ADB boot oem edl OK. (unforunatelly I have no screen print from this one).
You will know at once because your phone goes from fastboot (bunny) screen to black screen and enters edl mode, is normal do not be alarmed.
In your computer you will see now under setting> devices> Qualcomm HS-USB QDLoader 9008. That is a good thing you are now in edl mode.
From there go back to already running all in one tool.
Press the tab Flash Factory images, you will go to the respective screen (below).
Select Flash all, and press the download factory image china.
Immediately will redirect you by a pop up window to the chinese site of the MIUI.
Scroll down and you will come across the Redmi K20 rom, downloaded and save it to your desktop.
Once is done decompress twice from tgz. file, to tar. file, to ready to flash rom file.
Now come back to all in one tool, and select the rom from the browsing tab, go to the desktop folder where you have previously download the roam and select the ready to flash (unzipep file) once is loaded hit flash Rom and seat back.
The ADB terminal will start the flashing procedure you will know from the very beggining if everything is normal,
Because the terminal shows the file is being prossesed and the time for each action with a followed OK
During the procedure it will break up between two or three stages of the flashing, momentarily again do not be alarmed.
If everything goes well the operation will finish with a gorgeous redmi bootup logo.
(once again I apologize no screen shot taken in advance for this step)
It will finally bootup to system, allthough it might not, But one more time do not be worried, officially you have succeded reviving your hard bricked phone.
From there if is not completing bootup simply press volume up+power botton and you have the official recovery, (in chinese of course) but you can easily
find an image with the english tab designation, hit wipe data, and reboot again, voila there you are back in bussiness.
All the gredits go to the developers of the above used tools, since I just was lucky enough to find the way through.
Good luck to all Mi9T/K20 xiaomi owners with your phone revival process.
Best regards to all of you.
P.S.
Forgive my English for any syntax or grammar errors.
I wish I had more time to spend for a more comprehensive guide.
Works for k20 pro aswell?

Hi there I have not tried since I have only Mi 9T.
But yes, I am sure pretty much is the same think, instead of downloading the K20 rom, simply download the K20 pro one,
I wish you a good revival.
wow, this is too good to be true ? hope it will works for ppl who have brick. thanks
Awesome news, THX
Thank you for providing us an alternative way of reviving hard bricked devices. I hope this also fix similar problems but with a locked bootloader.
btw can i just unlock bootloader easily from this tool?
@Fantomduck Wait wait, i missread in your post "(only for unlocked bootloader)" So this is tutorial for those who have already unlocked bootloader to unbrick device or what? im confused now... bcs if we have unlocked bootloader there is no point to do this steps u described then, we can simply flash any stock rom on unlocked bl and unbrick drvice.
Yeah from what I understand, it basically flash the rom via EDL mode, but for unlocked bootloader. But why bother with EDL when the bootloader already unlocked? Also, I thought we can only flash ROM via EDL with authenticated tokens?
If this app can flash rom via EDL without special authentication, it should works for both unlocked and locked bootloader, though it might be different for Mi 9T Pro.
Very interesting nevertheless.
Hello again,
Just a clarification regarding, "I tried one more ultimate time, and boom success".
I ment tried one more time, by using alternative ways such the one that I post .
Not the Mi flash tool.
Well I guess thanks for taking the time to write this guide, however it's not applicable to hard bricked phones, and all the AIO tool does is use fastboot commands, that's the reason it requires fastboot access with unlocked bootloader.
Hard brick means :
- No fastboot at all. No way to boot to it on the phone. Plain black screen and nothing else.
- Stuck in fastboot with bootloader LOCKED and wrong ROM installed ("system has been destroyed"/"this MIUI can't be installed on your device")
Unfortunately for hard brick cases your only option will still require an authorized EDL account (and short the test pins for the 1st case) and only by using Mi Flash Tool.
Hi, yes I flased my phone via EDL Mode since I had no other option, (hard brick) the system was erased by a terrible mistake and the phone was only opening to fastboot mode, no matter what. And if you have hard bricked device you can not flash it in fast boot mode simply because your computer can not see the phone.

If your phone can boot to fastboot and the bootloader is unlocked then it's not hard bricked and can be recovered simply with fastboot commands. If you couldn't see the phone on the computer it was probably because of missing drivers or possibly fastboot/adb not running with admin rights, which I guess the AIO tool seems to fix with the "set ADB and fastboot privileges in system wide" option...
Yeah I thought so, as that app is basically a GUI version of fastboot and adb command. But I appreciate the effort to help people in here to recover their phones.

Dear ShiningScias.
Hello, well I guess then, I was on the shoft bricked side?
Thank you for making that clear to me, I then have to apologize, to everybody that I have mislead, with an assumption that was not the correct one.
I misunderstood what the hard brick is, I think probably i had jumped to that conclusion because when I was searching for rooting my phone I came across with so many tutorials and advices not to make any mistake while shifting between roms with ARB or else the outcome will be a hard brick.
Best regards.

Dear yumm91,
Hi, yes I flased my phone via EDL Mode since I had no other option, (hard brick) the system was erased by a terrible mistake and the phone was only opening to fastboot mode, no matter what. And if you have hard bricked device you can not flash it in fast boot mode simply because your computer can not see the phone.
Thus not adb debuging authorization to comunication with the device for reflashing. So only EDL Mode that qualcom put in place for such an awkward situation
At that time the only tools and knoledge I had regarding my newly purchased phone Mi9T was:
A) Flashing through Mi flash tool (which is locked for everyone to use without special account) I found it out afterward.
B) the all in one tool, that I found when I was looking for help in xda forums, which is for unlocked phones, as it states in the main window.
Said that before, I started looking for how to flash it in edl mode.
Nobody new then (a week ago) how to revive, bring back to "life" their phones( Mi9/K20 and Pro variants).
The general idea that was floating around regarding hard bricked devices.
Was the option of having a person with authorized account for flashing, to enter to your computer, and flash it for you,
( after opening the back cover and disconnect the battery, while make jumper between the the special points on the PCB).
To return the phone back to have it repaired, Xiaomi's suggestion.
I tried many times the mi flash tool, even when I was logging in, my xiaomi account said "this computer is bound to your account you can start now", but with no luck.
So Before I take my phone and bring it to a service center, for flashing for 55 euro.
I tried one more ultimate time, and boom success.
From what I know locked phones, can not be hard bricked since the system will not let you roll back, or flash not original xiaomi rom.
I posted the way arround to the Mi flash tool, that I came accross by trying to flash a bricked device , for everybody to overcome the authorization problem.
I am not a developer nor an expert regarding android programming, I just have little experience from previous devices that I messed arround by trial and error.

You haved probably problem with fastboot drivers for your phone. Bcs this tool u used to boot EDL mode is also using fastboot first to boot in EDL so how u boot EDL if u told before that your phone can't be recognised by fastboot on your pc ?
I guarantee u can easily unbrick device with unlocked bootloader using only miflash or using fastboot command on adb. So there is no point to do all steps in description.
Wait. If i will unlock bootloader, and for some reason it will fail and brick, it will be bricked on locked bootloader or unlocked?
Is this method works with a GLOBAL image flash to a chinesse K20?

maybe someone can try to do this tutorial if they have bootloader locked and bricked
Hello sir , i would like to ask that if u use AIO tool method, so will fastboot be locked after unbrick process ?

ODIN does not flash

Ok, yes, I found my old Samsung GT-I9505, decided to root it.
Understood what I need to do (however OEM was forcibly locked (I could not find the setting in dev options)).
Got into download mode, and: ODIN does not flash AP! It just does not. I pick the TWRP image, open ODIN, start it, and it just stops. No fails. I can only unplug the device to stop ODIN.
Yes, disabling Windows Defender and firewall and running as admin doesn't work for some reason.
Can anyone help?
Patching Android OS requires device's bootloader is unlocked. If OEM unlock option isn't offered in Developer options signals that unlocking the bootloader is denied.

LG K40 bootloader unlock

I just received an LG K40 and wanted to root it or potentially install a custom OS.
Unfortunately, it forced me to update upon resetting the device, which locked me out of being able to use mtk-su, the most viable root method. I regained hope upon seeing that I was able to tick "Enable OEM Unlocking" from the developer options, so it would be easy to unlock the bootloader.
For some reason, it seems like LG has completely disabled fastboot mode on this phone. If I hold down volume down and power at boot, I get LG's horrible stripped down recovery which is only a factory reset dialog. If I do the same but with volume up, the phone boots normally. If I hold down volume up with the phone off then plug in USB, I get to LG's download mode which can only be used to flash stock ROMs with their proprietary Windows-only software. With volume down, I get the "low power" screen that I would get if the phone's battery was dead.
These combinations are not documented anywhere and I have compiled them from various random sites and people from all across the web. I have tried many drivers, running adb reboot bootloader (which just reboots back to Android), and every possible combination of keys, but I cannot get to an environment where fastboot can be run.
Does anybody know of a method by which I can unlock the bootloader without using fastboot (OEM unlocking is enabled)? Or at least an alternative root method for this device not involving recovery or fastboot? This is a very tough issue to tackle.
there is a long outdated method to force (hidden) fastboot by erasing LAF partition, but I guess fastboot is meanwhile removed entirely so this would most likely just brick.
however you could try to unlock from mtkclient (should able to by-pass MediaTek Secure Boot)
Code:
python3 mtk da seccfg unlock
Perfect, I was able to unlock the bootloader from download mode with that application and install Magisk from there. Thank you for this!

The steps are outlined in this section of the README. The only difference is you should use stock Magisk instead of the outdated Chinese fork they used (the changes in that fork have been in upstream Magisk for a while now).
