My SAMSUNG Galaxy A8 2018 isn`t work - Samsung Galaxy A8 (2018) Questions & Answers

After rooting my smartphone, I turned it off and on again, and it booted up infinitely. I was embarrassed and touched this and that, then went to wipe->advanced wipe menu and accidentally changed the system file. After that, my smartphone doesn't work at all. I'm posting this because I wanted to know how to turn on this smartphone, so I hope someone who knows about this part will reply.
(OEM seems to have turned off as the OS disappeared when I judged it.)

So can you boot into anything? Try all button combinations possible.
Or it is just black screen without a single text no matter how ?

Now all of a sudden, a lightning bolt icon appears on the black screen, which appears to be charging.

Do not unplug your phone. Press and hold the Power key and the Volume down key simultaneously for more than 7 seconds. As soon as the screen goes black hold down Volume Down + Volume Up for a few moments.

The power button and the volume bottom button were pressed at the same time and pressed for 7 seconds or more. The smartphone was turned off. Since I used TWRP in this state, I have been routed using the powerward button and the power button to move the powerward button and the power button for a long time to move the BACKUP entry, and the system image is displayed, but the system is displayed as 0 MB. And if you try to reboot, the NO OS Installed error will be opened and you want to install the TWRP app, and Failed to Mount / System (No Such Devices) Error appears. Now this is the symptoms of my smartphone.

First, I asked you to go to download mode. How do I have since that? (OEM seems to be forcibly turned off when the OS itself is gone. I turned on the routing before.)

You are in twrp now, but shows system as 0mb?
Can you press mount> system or wipe> factory reset?

No. With OEM locked, even if your phone is locked as tight as bill gates's wallet, you can still boot into download mode. However You can only flash stock ROM in that case. This is the definition of OEM lock: you can flash, but cannot flash anything except stock rom.
You must not be meaning OEM lock.

I've just tried it, and they all give me a "failed to mount '/system' (no such device)" error.

Although I am looking for information on the Internet, it seems that a program called Odin is necessary for Samsung phones. The internet says that you can upload the genuine firmware, but is there any other way to upload this genuine firmware other than using Odin? And what should I do if my smartphone is not recognized?

What happens of you press reboot> bootloader in twrp?

When I enter reboot from twrp, four items are displayed on my smartphone: system, power off, recovery, and download. If you go to system, the Galaxy A8 logo is displayed and it stops, and if you go to download, it goes into download mode.
The bootloader entry is not visible.

When I went to this site, there was nothing of the Galaxy A8 2018 I wanted. So what should I do? Is it possible even if the OEM is locked?

When I went to the path where I had touched the system setting incorrectly and changed the system setting to ext2, what was displayed as 0MB was displayed as 7MB. After I just selected ext2 it was still showing 0MB, but now it shows 7MB.
But the no os installed error is still displayed.
However, the Failed to Mount / System (No Such Devices) error no longer appeared.

1. Then request phone's Stock ROM directly from Samsung.
2. As you were already told flashing a phone's Stock ROM doesn't require phone's bootloader is unlocked.
You reported you have flashed TWRP successfully: this means your phone's bootloader got successfully unlocked.
Take note that TWRP is used to flash Custom ROMs.

Stock rom: www.samfw.com
For odin and usb drivers just search
Flash in download mode

Odin doesn't seem to recognize my phone. Since the USB driver is a Samsung phone, I downloaded and installed the Samsung integrated USB driver. Yet it is not recognized. Download mode is now in the state.

I'm still a beginner, so I don't know how to flash custom roms or anything like that. Is there a way to flash a custom rom or original firmware using TWRP? Now, it enters the download mode and waits for it to be recognized by Odin, but it is still not recognized by Odin.
Does it usually take a long time for the smartphone to be recognized by Odin?

Do you have other phone? Is the cable good and transfering files?

Note 10.1 N8000 Won't start

Hello,
I tried to update my note 10.1 gt-8000 today using the instructions from droid opinion website. I did not remove any partition or stuff. Just uploaded the rom Image in AP, selected auto reboot and F reset time and this i. but when the phone went to restart, it wont start again. Its been 30 minutes and phone is still off. I press the power button, volume + power up or down but nothing happens. Is my tablet hard bricked? Any idea whats wrong with it? Please help me
Edit: I just noticed when I also put it on the charge, the screen doesnt turn on to show charging. So it doesnt even charge, the odin console had 1 pass and 0 fail. Any idea what went wrong?
Go back to Droid opinion they are responsible .
Reread and double check instructions and correct firmware for your phone .
My guess is wrong firmware what was the original firmware .

Thanks for your reply. So it means its hard bricked? When i plug in the charger it dont even show charging sign. Any way to fix it?
Does Odin work? If it works, try to re-flash your device according to the instructions. Otherwise, install the stock firmware.

Sure, I can help you.
What OS do you have? Try to install Fastboot and ADB tools. After that, enter in download mode (not recovery!) and connect your device with computer.
ADB Devices will test the connection.
Next use Fastboot to flash.
If you have questions, pleask ask them. It will protect you from wrong actions.

I got mine working by opening the back cover (check instruction from Youtube)
unplug the power plug (the black small block in the middle with Red/Blue/Black colour cables), leave it for few minutes, plug it black.
This will only work if you have the "Samsung Note 10.1 logo" flashing in loop on screen all the time.
Good luck

Bricked my Mate 8 when trying to go from NXT-L29C636B180 to NXT-L29C636B211

Hello everybody,
I managed to brick my mate 8 as per the title, honestly thinking why did i even bother, that whole saying "If it ain't broke, don't fix it." applies here 100%.
So i have been in the NXT-L29C636B180 which i put with the dload method (original was C636B103) and since then everything was good, all except the video camera that is.
So i wanted to try to get to the nougat update (561?) but i read that you need the 211 first. As i couldn't find it i used the android app: firmware finder, and using the proxy method i told basically the system that a new update is up and download it - so this is the update option in the settings..
So after it downloaded NXT-L29C636B211 then it restarted, starting unpacking, and the installation stopped at around 5% when it restarted by it self. And that was it...
I am in a screen where i cannot use the touch, but only the buttons on the side and have the options
"Reboot system now"
"Wipe data/ factory reset"
"Wipe cache partition"
Tried the cache and rebooting, didn't do anything.
Tried wiping, and reboot, then i go in another page
"Huawei eRecovery" where it asks to connect to the wifi and download but then throws an error message "Getting package info failed"
That is pretty much it, i tried putting the update.app in the dload folder in the sd card and tried to use that method but it wouldnt boot that (used the volume + and - and power buttons) but it took me back to one of the above.
Am i out of hope? Is there anything i can do to restore it?
I really appreciate the help.
same problem!

That happened to me too. you will still be able to enter fastboot. plug your phone to your pc and and press and hold the power and volume down. that should take you to the fastboot screen.
find the appropriate twrp recovery for your phone and use the command
fastboot flash recovery "recovery name".img. wait till its done.
press and hold the power and volume down button till the phone reboots. that will takeyou to twrp recovery. there you could either flash b210 or the beta b521 -- which i am on.

Thank you for the response. I will give it a try today after work i am a complete noob so its the first time for me to see what fastboot is, never heard of TWRP, i was always stock so never needed to mess with my phones.
If i recall doing power and volume down while plugged it was taking me to the page i mentioned to wipe the data, reboot or wipe the cache.
I managed to go to the fastboot page on the phone by pressing volume - and then plugging the phone to the pc. Now in the white page on the phone it shows, Phone unlocked in red. Does this mean just it is carrier unlocked?
So do i need to have the bootloader unlocked to do anything here? How do i do that? I cannot buy the code i suppose now since my phone is bricked i will have to go the Huawei way? And how do i do that, i saw a site to create a HUawei ID but in the registration page it didn't mention UK anywhere (where i live), mentioned Hong Kong and other Asian territories. I bought the phone from Wonda mobile, and being the 636 i would think its the asian model anyway.
Regarding TWRP, i didnt install it from before the phone was bricked will i still be able to do what you mentioned? And for the image i need to use, do i need to go to the firmware i was in before (636B180) or the one i tried to go to (636B211)? I can't seem to find the 180 anymore anywhere.
Sorry for the mass amount of questions, trying to sort it i have the phone for less than a year and i am gutted for messing it up like that.

Remember you need to root your device first.
In order to apply the ne IMEIs, the app requires you to share, you can just share to a fake contact

Hey, thanks for the links and all that but when I press volume up + power, it boots into a screen where it says "kein befehl" (which is german for "no command") and if you then press volume up + power again it will boot into the stock recovery ("Android Recovery"), but not the TWRP Recovery.
I used SP Flash Tool as administrator and it said that the download succeeded.
My phone had OEM Unlocked and USB Debugging active. (Oukitel K4000 Plus)
Could you please help me get TWRP going or maybe tell me an other way of getting root installed?
Any help is appreciated!

You should not turn on your device before booting into TWRP otherwise it will be overwritten by the stock recovery automatically

Thanks for the answer!
But I didn't turn it on before. What I did is:
Unlock OEM in settings + enable USB Debugging
Turn off the device
Start SP Flash Tool as admin, select scatter file, only check 'recovery', set to 'Download only'
Click the 'Download' button, then AFTER that, connect phone to PC
Wait for the downloading process (takes like 3-5 seconds) until it says "Download Ok"
Disconnect phone from PC
Hold Volume UP + Power
Oh and what I forgot to mention is that when I hold Volume UP + Power it boots up until the point where you see the Oukitel logo (not the animated one) and then it just resets and once again boots up until it gets to the Oukitel logo and it keeps on doing that until I let go of Volume UP + Power for a moment and then start holding it again when the Oukitel logo pops up again. THEN it resets into the "kein befehl"-(which is german for "no command") screen (which I mentioned before).

You should let go ONLY the power button as soon as the screen turns on.
Solved
EDIT: Thank you, I used an other version of TWRP (this one) and it works perfectly fine now. Have a nice day

If I let go of the power button (but not the Volume UP button) as soon as the screen turns on (the Oukitel logo is displayed) it will still do what I described (it keeps on resetting on the Oukitel logo).
Edit:
1. I have read something about that you need to unlock your bootloader (additionally to Unlocking OEM and enabling USB Debugging) first. Could it be that this applies to me as well? And if yes, what do I need to do?
2. The first time starting the phone it asked me to do a system update. And I let it do the update. Could the problem be that you need the version of the system that was on the phone when it was delivered? And if yes then I only need to do a factory reset before rooting right?
3. If I dont flash TWRP then I get into the recovery without problems, but when I flash TWRP onto it then it does like described above (keeps on resetting).

White Screen fixable?
Quite disappointed. Used Oukitel models before and have never had a problem adding a custom rom or changing back to a stock version until now.
Ended up with a white screen.
Followed the instructions from this website
https://romprovider.com/2017/08/download-firmware-oukitel-k4000-plus/
Did exactly what it asked which seemed logical.
The stock rom came from here
https://www.needrom.com/download/oukitel-k4000-plus/
However I now have a white screen. How do I go about fixing this? I defnitely have a Oukitel K4000 Plus (sticker in the battery)
Don't worry, I had the same problem. There are two versions of k4000 plus. The newest requires at least firmware version 1.5 and you probably installed 1.3 stock.
Download 1.7 firmware from 4pda. I cannot post the link so search on google...

Thanks for that. Applied version 1.7. Device accepted it which is great. Battery not recharging through but no white screen!. So at least one step closer.

I've rooted my Pixel 3 as described here in the forum.
Everything went well and I was booting in TWRP without any problems; Bootloader is still unlocked. I didn't installed a custom ROM or anything else. After I've selcted "restore backup" my backup (which I've made before with TWRP) my phone is now messed up:
It's starting in Bootloader (Warning Screen for unlocked Bootloader) and than is switching on an white screen with Google logo for ca. 3-4 sec. and than it's jumping back into the Bootloader in an endless Loop.
Any idea what I can do to rescue my phone?
Thanks, Mags

In bootloader mode can you get your computer to recognize the phone. If so, download the latest update from Google website and install using adb. This will wipe the phone but will get it restored. I've had to do this in my pixel 2 before. I don't have the pixel 3 yet as I just ordered it today.

You can also edit the flash-all file to remove the -w and not completely wipe your phone. This way, your data will remain and it still resets the important factory stuff.

Thanks, I‘ve tried with adb devices & no device found. So obviously my computer doesn‘t recognize the Pixel

Thanks. Loosing my data isn‘t the Problem. Actually I‘m even not able to connect to the phone and flash anything.

Have you hard powered the device down and then rebooted to BL with key combo to check connectivity?

Hold down the power button until the phone completely shuts off. Hold power while holding the volume down button (start by holding the volume down and then immediately start holding the power button - it's is technically holding both at the same time but starting with volume down just a moment before keeps you from pressing power first). That should get you to fastboot.

ADB doesn't work when booted to the bootloader. It only works when you're booted to the OS. To see if the computer recognizes the phone when in the bootloader, use fastboot devices instead of adb devices.

Holding the power button didn't had any effect, but holding volume - and holding power button at the same time was starting the bootloader and so I was now able to start TWRP Manager.
So if you could help me from here to fix the OS would be great, e.g. is there any chance to copy the original OS from Google or an custom ROM from my computer (e.g. I wotk on MAC and is there a way to copy via Terminal?) or does TWRP offers any way to reset/ reinstall?

Yes, the computer recognizes the phone (via Terminal on my MAC)

Sorry, but I do not know the Mac commands, but if you are in Fastboot and the device shows/connects it is just a matter of running the flash-all and resetting. If you are not connecting in Fastboot but can get into TWRP, I would start with a reset in TWRP.

The commands on the MAC are almost the same and with your flash-all (flash.all.sh Mac Command) it worked very well with the factory image from google. Now I'm back in the race and my P3 is running again.
Thank you all guys!

Excellent news. On another note... if all you need from TWRP is to install Magisk to root, you do not need to permanently install TWRP. Just fastboot boot the [twrp].img file, install the Magisk .zip and keep stock recovery.
From messing around, it seems that trying to restore system from twrp is messed up. Data backup works fine. The only other way I got bootlooped was by messing with boot, vbmata, and vendor partitions. Out of those three, I think boot is the most likely to get messed up by normal users. I know this is sorted now, but in the future try to just reflash boot.img and see if it boots.
-The vbmeta and vendor thing is specific because I need to get the radio to work here.

sm-g930t bootloop help :(

Hi, I'm new here can anyone help me my phone is stuck on bootloop keeps restarting, I've tried flashing lastest stock rom via odin and it successfully pass, tried factory reset and wipe cache partition on recovery menu but still bootloop. I badly needed help even my local shops here in our town don't know what to do. Lol. Also the recover mode says no command with an exclamation mark and a dead android logo. Any replies will be much appreciated, thank you.

press and hold your phone’s volume up button for 10-15 seconds.
2. Next, without letting go of the volume up button, press and release the power button once. It will display a menu.
3. Navigate around the menu using the volume button.
4. Select Reboot System Now and your phone should be rebooting
Alternatively, you can do the following:
1. When any of the three appears, press and hold the power button for 2-3 seconds.
2. Then, without letting go of the power button, press and release the volume up button, once. It will display the same menu.
3. Select Reboot System Now and your phone should reboot.

OK lets start from the beginning
Where did you get the phone from?
What firmware was on it?
What cell network are you using?
What country are you in?
Can you still get it into download mode?
Where are you getting firmware from?
What version firmware are you trying to flash?

Tried it now, still the same results. Thanks tho for constantly replying to my thread sir.
up please, still didn't solve my problem.
Check to see if you're running the latest odin. New odin software should be 3.13.1. Make sure to right click and run as administrator when running the application. You could also try using different computers and USB cables. Unlikely but if it works, it works.
Also, try downloading the file from a different website, there's a possibility that the file is corrupted. https://updato.com/firmware-archive-select-model/
