Lock Bootloader

Hi, I unlocked bootloader but I want to lock it back because I pooped everything. How to do that?
Also why eRecovery always writes "Getting package info failed"? I have PRA-LX1C432B172 Doble SIM.
Sorry, I'm a newbie and I regret my decision. I don't understand anything. I want to turn everything back.
But please help me!

1)Connect your phone with the USB Cable to either it's charger (not a third party one) or your PC.
2)Shut it down and wait till it shows the charging animation.
3)Press the Vol.+ and Power buttons together and after the Huawei Logo appears, release the Power button but keep holding the Vol.+.
4)Keep holding even if the "Your bootloader is unlocked" warning is displayed.
5)If all goes well you will be at the eRecovery part of your recovery. If you go to regular recovery try again switching from Power to PC and vice versa and keep trying with the buttons.
6)Connect to your WiFi (no need to have set it up from Android in order to work, it has a minimal interface with keyboard to do that).
7)It will show the latest stable release of the OS (around 2.3-2.5GB, I hope you have fast connection) and choose to download it.
8)After it downloads and installs EVERYTHING from scratch (it will also relock everything, so keep your phone above 80% battery life and don't overcharge it), it will restart and after that shut it down again, if I remember correctly, if not choose to shutdown.
9)Without a USB connected press Vol.+ and Power buttons and after the Huawei logo appears release the Power button and keep holding the Vol.+ button.
10) You are now in stock EMUI Recovery, do a factory reset and Wipe Data/Cache and restart.
11) Redo the setup and you are good to go.

Hi,
I have J415 in hand and I believe you can follow these steps:
1. turn off the phone
2. hold vol up+ vol down and connect usb
you should be in download mode now.

Recovery
Plz i want link to twrp (recovery) of samsung j4 core (SM-J410f/ds)

I also have a this issue. Power & vol+ & vol- plug in USB, Samsung logo then a blue screen, possibly with an exclamation mark, but only for a split second. The reboots and does the same continuously. I was on android pie uk and tried to flash twrp, failed 3 times. Tried to reflash 8.1 which ended in a fail and now it won't boot, won't boot recovery and won't go into download mode. Does this mean a flat battery? Should I leave it on charge with no sign it's charging? Hold the 3 buttons on reboot for 5/10 minutes?
As it stands now, it's not bricked but I can't do anything with it.

I solved it by holding all 3 buttons and plugging into USB, it did the whole rebooting thing as usual but I kept the buttons held for about 15/20 reboots and then it FINALLY went into download and I could flash stock rom. If important or not, I'd left it charging all night but showed no sign of life whilst it 'charged'

have same problem same it is kind of security to avoid writing Combination

(help) Bootloop after OTA update

Hello
My stock A515F/DS received an OTA about 3 days ago. After it restarted to finish the update, it got stuck in the boot logo. It will reboot on itself from time to time, and I was able to reboot it manually by pressing vol down + power, but I can't get into recovery or donwload mode (by pressing vol up as soon as it reboots). The screen flickers for a moment, but it reboots again. We are under quarantine by federal law so I can't get my phone to samsung. Is there any way you guys know to flash it without going into recovery/download mode? I don't mind losing my data, everything is on my drive account, I just want my phone again
Thanks in advance

I think there is no way without entering in download mode or bootloader. Try with this:
When the phone is on, no matter which state, press Vol down + power until it reboots. As soon as the screen goes black, change to Vol. up+power. If this is successful, you can then select Reboot to bootloader to enter in download mode.
If this doesn't work, the next solution is waiting the end of quarantine

I Flashed My Note 20 Ultra With Recovery.img And Now Its Stuck On Orange State "Bootloader Unlocked" Warning Message!

Ok Guys So I Shouldn't Have Done This But I Used Fastboot To Flash Recovery And I think I Did It Wrong. It Said "ok" And Finished And I Rebooted Phone It Resetted And Then Stuck On The Orange State Bootloader Message. I Do The Recovery Mode And Goes Black And Nothing Is Responsive For a While, Sometimes Longer Than Others. This Happens If I Start Phone Normal Or Try Fastboot Or Download.
Because Of My Mistake I Cannot Connect To Pc Software And Im Not Sure Of What I Can Do. I Feel Like Im Not Going To Like The Answer For This But I Got To Take The Blame For This.
Btw i Have A Samsung galaxy Note 20 Ultra Sm-N986u

I think your phone is hard bricked

so you can't get fastboot using volume up+power or via adb?
rescue from manufacturer site pos or just device not being recognised?

It isn't hard bricked it's just way of Samsung trying to make life of simple people more difficult, people who paid for Samsung phones lots of money.
To sort that screen issues what you can surely do is,
Simply press volup + voldown buttons at the same time, no matter if you're on that orange screen or whatever just press those those two buttons at the same time and keep pressing them while you connect your phone to pc. you will boot into download mode. Then flash stock firmware for your phone. After stock of flashed Reboot and start your phone, go to developer options see if oem unlock option is there if it is then oem unlock it if it is not then go back to settings manually change date to year ago, then go to updates disable auto update, connect to WiFi, and press on update several times untill window shows up saying no updates, then go to developer options you should see oem unlock, unlock it.
Then boot into download mode and make sure you have working copy of recovery.
And make sure you follow instructions of whoever recovery you installed on how to boot into recovery. I have S20 plus and too had troubles with it, and the only working recovery for my phone is twrp customised. To boot into it after flashing recovery from odin auto reboot disabled I pressed voldown and power, USB cable connected, then after screen goes off I changed from voldown to volup while kept pressing power button and cable connected. Orange screen with warning showed up for 5 sec I kept pressing and it bottled to twrp and then I was able to install custom rom beyond rom and while installing in aroma I was able ti choose option to remove orange screen.
That's it.

I ran into the same error. I mistakenly loaded twrp's recovery into userdata instead of ap section. The phone was stuck at the orange screen and nothing was happening whatever i pressed. I waited till the battery to dry out and with 0% battery, i directly connected to pc and was able to get into download mode. Then i flashed stock and everything is now back to normal.

Not able to get into EDL or Fastboot

Hi Everyone,
Recently I have unlocked the bootloader and flashed twrp after upgrading to OOS 13 after that I have not able to access any storage(including OTG) so I had changed the format of disk. Now its stuck is bootloader and show qualcomm icon when starting and just keep on trying to boot(stuck at logo not a loop or anything). I am not able to get into the EDL mode or fastboot for that matter any suggestions
Video is uploaded to show the icon it continues to normal oneplus logo boot and stays there

can you hold vol - and power with it unplugged until the screen goes black, then fast as lightning hold both volumes and plug it in? I used to have this device and I'm trying to remember what I did to get out of that.

I had always waited till the phone got discharged and then tried again EDL used to work when I had the flashboot but now it not a possibility it resumes into the unlocked bootloader alert (sometimes press power to pause or continue to boot) and then logo not matter which combo of the buttons I tried

If nothing works you can always take the back off and unplug the battery.

Doesn't discharging the phone will also do the same or are you suggesting me to go into edl by removing battery cover and plugging in like the old mediatek recovery method

Have you tried unplugging the device, using volume up and power to fully shut off the device, then wait a second, and switch to volume up and down, while plugging in? Important to keep it unplugged until going into EDL.

It's already fully shutoff when I discharge it to recover from the boot animation. The keys combo don't work at only power button work to continue or pause boot
