How to install Android with LB

Hi guys,
I think I messed up my phone big time. I had problems with turning on wlan, so I tried Rebooting and Factory Reset but without success. Next I wanted to reinstall android via TWRP like I would do it with my PC. Now I have a Phone with an empty internal SD Card, locked bootloader and no idea how to fix it.
The PC Companion or any other program does not recognize my phone.
Is there any way to install Android again with a locked bootloader or can I unlock the bootloader without android?
Hopefully anyone knows a solution and I do not need to buy a new phone.
Thanks in advance!

thanks a lot but so far did i get myself before even posting here ...
i cannot enter flashmode via android obviously and via the volume button is not working, the led does not flash and flashtool is not recognizing the phone when i try it

Plug it into a wall charger for 24 hours and then try again.
Also, sone information from your device manager in your pc may help and what scaly you flashed in recovery to get into this situation. Its very difgicult to offer advice on such limited information.

Problem is fixed, i got a new mainboard ...

[HELP] Bricked Oneplus 6 - Qualcomm CrashDump - already tried everything

Hi everyone!
Well guys, sorry to bring this subject on thread again (because this forum has a lot of guides to solve this problem).
But I'm without hope with my phone at this moment.
Let me tell you guys my sad story...
I have an Oneplus 6 since december 2018, and never, NEVER, tried to use any modification on my phone.
I am from Brazil (so sorry for my bad english =] ), and here we CANNOT use Oneplus Support services (I've tried but only received the response "sorry I cannot help you on your country"), so because of this, I've decided to never apply any modification to avoid problems.
This week after a simple reboot my OP6 started with "Qualcomm CrashDump" error and my despair begins.
I'm not able to enter on Fastboot Mode. When I try, the systems attempt to boot (the fastboot mode logo appears) and fall down into crash again.
I'm not able to enter on Recovery Mode either. This method shows nothing, only black screen and after some time the crash screen comes again.
I do not have Bootloader unlocked too.
Any suggestion to use TWRP via fastboot.exe or ADB are useless, because I cant make the connection. At least I think that is impossible because the 'adb devices' command does not find the device.
I followed a lot of guides from XDA to solve my problem, including the Mega Unbrick Thread.
I already downloaded at least 8 different versions of msmdownloadtool in consecutive attempts of unbrick my phone. Nothing really helps.
The most weird situation is that msmDownlodTool can finish the proccess with success. The driver installation is working... everything seens OK using the tool but my phone does not revive
Someone have a suggestion for me?
Any suggestion, tool or alternative method is welcome in my actual situation.
Sorry if I posted at wrong local, just tell me and I can fix if necessary.
Thanks in advance to all of you guys.

Hi!
Thanks for your reply, but I think you do not read my entire post
As I said, i've already tried at least 8 different versions of msmDownloadTool.
If you have any other suggestion, I'll appreciate.

so you can't boot into fastbootmode anymore?
Had the same problem once before and solved it by flashing the correct twrp by fastboot

Yes, I am unable to enter into Fastboot Mode.
When I try, the logo saying "fastboot" appears, but after 4 seconds, the systems stucks on CrashDump error screen again.
That way my PC cannot find my phone with ADB or FASTBOOT commands.
The only tool that works is msmDownloadTool, but even with a success run with that tool, my system does not start and stills under CrashDump error.
I was thinking if exists some version of msmDownloadTool that justs restore the fastboot and unlock bootloader with brute force.
Thats my last hope

Source is a videotutorial. google oneplus 6 hardbrick and click the video of Max Lee
(it worked for me)
the download takes an awful lot of time
first get your phone into qualcomm download mode by holding down volume up + power button and plug your device in your PC.
(first unzip the hardbrick zip folder) then the oneplus 6 folder and than the .exe file and click 'start' if it detects your phone.
That is flashing every chip and Hydrogen OS 5.whatever.3 but that is not important. Your phone should boot and than you can install Oxygen OS with android 10(thats the other zip folder) using the local upgrade feature.
(make sure to enable google play services after upgrade from hydrogen OS)
Hope it will work for you too if you haven't tried it already.

Your device is corrupt. It can't be trusted and it will not boot

Hello,
So, apparently i messed up. I installed nethunter on my phone, everything was working well, finished the configuration and then i had the idiotic idea to lock the bootloader since it was locked at the beginning when i received the phone, so i locked the bootloader not knowing the consequences of that.
Now i don't have how to go to enter in recovery mode, i can't boot. The program adb and fastboot doesn't detect the phone when i do adb devices or fastboot devices. I don't know how to proceed from here.
Any ideas ?
Kind regards,

Fastboot, Samsung Galaxy A51

Hello, i wanted to ask how to fix the fastboot mode.
Everytime when i try to access it, it just says "Entering Fastboot..."and thats all.
I dont want to close it, thats not my problem, i just wanna flash a recovery.img, and the fastboot seems not working. Any ideas?

this could be because the galaxy A51 wasnt built with fastboot, and the code to launch this option was just reused from a different device, or because something isnt connecting properly.

Hello, I have the same ... Android 11 (and currently 12) (from Frija). So it is not the fault of incorrect configuration or with connecting. Only something is wrong with this phone ...

I have this device and this solved it for me:
Enable OEM unlocking in developer settings
Shut down the phone
Hold volume up and volume down
Plug in a USB cable connected to a computer (the computer being turned on)
Keep holding
You're in download mode!
Side note: This might not work in USA or Canada, I am from europe and it works here. I have no idea if it works in another region. Also, you can't just flash a recovery.img on Samsung since there is no real "fastboot", you have to use download mode and Odin.

But I know how to enter download mode... Problem is Fastboot mode...

There is no fastboot mode on a modern Samsung device. If there is, it's fake and you cannot flash anything with it. As you can see even from Wikipedia, Odin is the Samsung replacement of fastboot.
So no fastboot, only download mode.
If a guide is saying to use fastboot, it is not compatible with Samsung.
If you would tell me why you specifically need fastboot, I'll be happy to tell you how you can do it with Odin, if possible.

Because I have Samsung Galaxy A51 5G (A516B) with new Android 12 and I can't do a root! Because I can't upload TWRP (custom recovery) because I haven't OEM unlock option in Deveoper Option. I tried trick with set back date by 7days but not succes. Everything I;ve metioned here - I did at my phone with Android 11.
And... I have read that I can turn this fu**ing OEM option by comend at ADB: fastboot oem unlock.
Phew ...
So this fastboot method is the last method to do a root with my phone.

Upload TWRP by Odin in download mode -ends red warning - of corse...
Have you any ideas?
I would be grateful for help...

I have read this fastboot method at:
How to Unlock Bootloader On Samsung Galaxy Phones [EASY GUIDE]
Are you looking for a Complete tutorial on How To Unlock Bootloader on Samsung Galaxy Phones? If yes, then you have come to the right place.
www.guidetoroot.com

Yeah, that guide is not relevant on any modern Samsung device. Besides, even if it was, which it isn't, you would first need to enable OEM unlocking from the Developer Settings.
But the fact that you don't have an option for OEM unlock is weird, since I have the exact same device model and it is there for me.
May I ask what is your region and is your phone locked to a telephone carrier?

My region is PLS - Poland. And not - phone is not locked. Have you the newest system Android 12?

Yes, I do. It's weird that there isn't even an option for you.
I'll try to come up with some new ideas if I have time...

I'll be glad for it...

Hej, do you have any idea?

Yes, I did. Evething exept the last one...

You could try it. It might be risky, but it's the only option I personally can come up with right now.

I've tried this option but Odin stuck on "files verification". Any help?

have any of you encountered this problem?
And how did you solve it?

You can also try searching for combination firmware for your device online

Question Rog Phone 5 Brick

Hello to all,
I apologize in advance for this message.
I mistakenly bricked my phone,
It was running WW-18.0840.2201.226 (Android 11).
I'm not sure if I'm going to be able to use it again, but I'm sure I'll be able to use it again in the future.
The recovery mode does not work anymore. It remains stuck on the logo.
Concerning the device manager :
In Bootloader, nothing is detected
When I test the recovery mode, it detects 'Android Composite ADB interface'.
However, the ADB commands do not work (Unauthaurized)
This is a call for help, I don't know which tutorial to look at to help me.
Do I need to get a Deep Flash Cable to restore the phone?
Excuse my English, I'm French ^^'

Hi, I'm not sure, but I think you will have to delete this POST... It doesn't respect the forum rules... That said, you can follow this link for your problem. https://forum.xda-developers.com/t/...to-unlock-bootloader-to-modify-country-cn-to- ww.4353865/não lido

Hi Rico,
If I have to delete the post I will do it, it's not a problem.
Do you think I can put this post in the topic you gave me?
I had come across it in my research but I didn't know if it needed a Deep Flash Cable
I didn't know that my problem was similar to the one in the post because I don't have a 9008 mode

There is nothing wrong with your post at all.
Do you have access to see and send Fastboot commands to the phone when on the bootloader screen? You need to get that right first and get your driver on your PC sorted. Forget ADB, that's not going to help you here.
Once you have sorted the above, doing a RAW flash following one of the guides you can find on this form with a rom version that matches your device should get you back on track.
At this stage you shouldn't need EDL or a deep flash cable before exploring the above option.
Good luck.

Hello Andrologic,
Thanks for your reply
I only have access to the Bootloader with 'Start / Restart Bootloader / Recovery Mode / Power Off'.
I bought a Deep Cable, this one detects me when I connect it to the pc, previously my other cables did not want it
So I can indeed use the Fastboot commands whereas before I couldn't

Thank you very much Andrologic!
The phone works like magic again, I can't believe it T_T
When I should do the updates, should I reflash the phone?
It doesn't offer me any new ones even though I'm on Android 11

Nice. No, I would suggest updating the conventional way, i.e download ROM for ASUS and let the device pick it up and flash it. If you have TWRP installed, you can flash from there too, but there is no need for that unless the first method is not working
