Hi all !
I have a Samsung A8 (model SM-A800F) which was working great. I ran Kingo Root to try to install Youtube ad free. The next time I restarted it, it didn't load, and restarted in an endless loop to where "Samsung" logo appears (then restarted again). I booted into System Recovery and chose to reset to factory, but it didn't help. Then I tried flash it using Odin in Download mode. I installed the Windows drivers, downloaded the 6.0.1 firmware for Vietnam (where it was purchased), loaded the file into the AP field, and once verified clicked Start. The progress was frozen when reaching mid-way every time I tried, until it said "an error occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software"...
I downloaded Smart Switch and installed in Windows, but the drivers were not able to install correctly, and failed on the component referring to the ID or something... while Modem driver was installed correctly and the phone appeared in Device Manager. Smart Switch didn't recognize my phone and said "unsupported device".
Now I cannot get the phone stay constantly ON, and the screen shuts down and loads in an endless loop, to the "Error occured" screen... When trying to boot to the ODIN Download page, it loads, I press UP for Continue, and then it again shuts down and loads to "Error Occured".
I tried to charge over night but it didn't help. It does the same thing when the phone is connected to the charger...
However it seems that by IMEI it is sill under warranty. I'm not sure if I voided it :/
Here's what the Download mode page says:
ODIN MODE
PRODUCT NAME: SM-A800F
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
FAP LOCK: ON
Secure Download: Enabled
KNOX WARRANTY VOID: 0
AP_SWREV: 1
Would appreciate any help, this phone is almost new but now it's dead :/
Your warranty is not voided. Your Knox E-Fuse still intact.
Also this is for S8 not A8 forums.

Thanks,
I just couldn't find any A8 forum, and thought there would be more people here who can help.
Would appreciate any help on this... thanks in advance

No worries, your phone is not dead.
Try to find a firmware that correspond to the one you got :
http://updato.com/firmware-archive-select-model?exact=1&q=SM-A800F
and use ODIN : http://dl.sammobile.com/Odin3-v3.12.7.zip
You should be good to go.
EDIT : Also for that error occurred thing, try to be faster than it by starting odin flash before it appears.
Thanks,
The problem is that neither the error nor the Odin page would stay on for more than a few seconds. Once they appear, the screen would go dark after 5-10 seconds and then the "error" page would load again (after being darks for another 10 seconds or so). So I can never have ODIN or Smart Switch connecting to the device (the drivers won't connect in Windows)... making it impossible to upload any firmware.

Could you take a picture of that error ? I've never heard/seen such thing
Hi, thanks for the help !
The error is this:
http://statics1.grupoandroid.com/up...1850.jpg.d2bb2a8b77e4fba5fc6467f3d1547886.jpg
I *think* I have some direction... here's what I did/found:
- I installed Smart Switch on my Mac, and chose "Reinstall Device Driver" from the menu. Then restarted the MAC
- I loaded Smart Switch, and Chose "Emergency Software Recovery and Initialization". Then chose the "Device Initialization" tab
- Added the model number "SM-A800F" and the device's serial number (which are physically written on my device).
Smart Switch determined the firmware version to be used for initialization, as:
PDA:QC3 / PHONEG3 / CSCH4(XXV)
- Smart Switch asked to:
1. Power the device down
2. Load recovery mode by pushing Power+Vol Down+Home, then connect the device to the MAC and choose "Continue" to start the initialization...
The problem/s:
My device won't turn on at all, if I do not connect it to either the charger or the MAC (which acts as a supply source?) - which makes me think the battery is fully drained ? i.e when not connected at all, it won't power on.
But when connected to either the charger or MAC, it would bootloop endlessly. i.e it will load the "error" page mentioned above, shut down itself, reload again, shut down and so on.
(I have to mention, that when I first noticed the bootloop, I reset everything to factory settings, cleared cache etc, and it still bootlooped on the Samsung logo).
If when it shuts down during the loop, I push Power+Vol Down+Home, it would boot to ODIN recovery page, where I can push UP for the Download page, but it will still reboot and will again load into the "error" page, which will again reboot endlessly. If I take the charger off the device, it powers off and won't load with any combination of button push.
I also cannot just make it shut down when the charger is connected, using any of the possible button combinations...
I wonder:
- Is there there's a problem which prevents the battery from being charged at all ?
What's strange is that the original problem which made me get into this whole issue, was that is was endlessly booting to the "samsung" logo - but when I booted to System Recovery or Download/ODIN modes, it stopped rebooting endlessly and stayed on... it was also showing the charging indication when powered off... the battery was charging well ever since.
- Why would it bootloop when connected to the charger ? is it possible that the bootloader went bad during my attept to install firmware using ODIN ? I know it always went through the boot.img and recovery.img successfully and only got stuck at about 50% when installing system.img...
I think the current bootloop problem began only once the battery ran out of power. But why wouldn't it charge at all now ??? It's supposed to still charge in this state, isn't it ?

Hmmm, the thing is, the battery charging process is actually held on some kind of "mini-boot" OS on Samsung I believe, where the phone boots into a certain state, with that said mini-os to display the battery charging info and this kind of things.
My guess is that you *might* have, or more likely your phone did corrupt the flash at some point for x or y reason.
What I'd do is :
Let the phone on a charger a whole night doing its bootlooping thing. And see from there if the battery would charge.
I'd try another computer with Odin just to be sure something is not triggering the reboot process at some point.
And if all the above fails, you still have the warranty, so beside time, you would not be losing any money..
I'm going to write a long post. But I believe it will help a lot of people having a similar problem.
Long story short - problem solved! but it took much of my nerves (and time).
I'll start with the "warranty". The so-called Samsung "warranty" which basically worths nothing!
Calling Samsung international service center, they "informed" me that I must contact Samsung Vietnam, where I bought the device, although I am not there anymore... Needless to say the local dealer in my country refused to take care of this situation, saying Samsung's warranty is regional based, rather than international... which means, only Samsung in the original country where the device was sold in, are responsible for the warranty (and therefore repair!). I had a chat with a Samsung Vietnam representative, who just kept saying "I'm sorry", and refused to let me sent the device out to them for repair! asking me to "bring it to them", although I noted him a few times that I bought it as a tourist and I am not in Vietnam anymore.... Thank you Samsung !! From now on every traveler in the world will know they basically have NO WARRANTY if they buy any Samsung device in a "foreign" country while traveling abroad!
Now for the solution:
I started by letting the device staying connected to the charger overnight, which didn't help. With the OS now installed, I realize that the battery was NOT CHARGED ! it was completely drained, although connected to a charger for long hours... So, know from now on that if your boot data is corrupted, it may cause the device NOT TO CHARGE THE BATTERY at all. Luckily, my desktop PC could use the device while connected to it although the battery was empty, until the problem was sorted out. I did get a crash on my MAC tough (Log said it was USB related), while using Smart Switch, so one option is that it could not supply enough power to the device to keep it keep working at all, or working correctly... So my suggestion is to use a desktop Windows PC in this case, which can potentially provide more power to a device with 0% battery power.
After scratching my head, and considering removing the front panel for replacing the battery (a very risky procedure) I decided to keep on investigating....
I followed a youtube video who suggests that you should install Smart Switch on a PC, choose "reinstall driver" from the menu, restart the PC, then use Emergency Recovery and Initialization, enter the phone model number in the search box (as appearing on the back of the device) , and once it recognizes the model, also to enter its serial number. Here's the video:
https://www.youtube.com/watch?v=1yXQUFrEWg4
This basically brings up a popup message saying Smart Switch detects a compatible firmware for this device, and is about to download and install it. It then asks the user to do the Power+Vol Up+Home push combination trick + pushing UP once the page is loaded in order to "Continue" and bring up the ODIN Download screen, which worked for me if did that as soon as the device shuts down (in the middle of the bootloop). As I couldn't make it load at all with no charger connected, I had it connected to the charger, and once I saw the Smart Switch message asking to do the push combination, I quickly connected it to the computer using another cable which was already connected to the PC USB port on its other end.
Somehow, I could at last make Smart Switch finally start downloading the firmware from the web, and the device again disconnected (bootlooped), but luckily Smart Switch didn't care about it disconnecting, and kept on downloading the firmware. At about 85% of the progress bar state, I could find the downloaded firmware on the temp folders, which are described in this thread:
http://forum.gsmhosting.com/vbb/f777/samsung-firmware-download-belongs-his-serial-number-2038404/
I had to make sure it wasn't still downloading, and watched the "last modified" state of the file to make sure they are not being downloaded anymore. CAUTION: although the AP was not downloading anymore, I know it was probably not good as ODIN couldn't verify it when I tested it. USE ONLY SMART SWITCH !
I quickly copied the folder to which the app extracted the BL and AP files it downloaded, and finally had an officialy bootloader (BL) image, which I could use in ODIN in order to reupload a correct, "official" bootloader to the device....
I hoped the device won't bootloop in the middle, but luckily ODIN was fast enough to send the image successfully, with a "PASSED" status, and the device booted with a nice "Samsung" logo directly to a System Recovery page!
What I exactly did, was loading ODIN, then loading ONLY the BL file into the BL field in ODIN, having it verifying it, and once verified I connected the device, and as soon as ODIN recognized it, pushed START. It managed to upload the image into the device in a few seconds! It seems then, that the bootloop was not caused by a bad battery, but as a result of a corrupt upload of an AP image through ODIN - or because I possibly was using an incorrect version when I tried to upload an AP files to the device on my first attempt to flash it.
Note that I did search for the correct, compatible AP file, by country and model (on Sammobile) but it didn't' work (stuck at 50% in ODIN) ! so I really suggest everyone TO ONLY USE SMART SWITCH if they want to be sure that the correct firmware is being used, and avoid similar situations...
I then deleted the temp files from the PC (the actual ones which were in the temp folder), reinstalled the drivers from inside Smart Switch (just in case), booted the device to Download mode (WHICH DIDN'T BOOTLOOP this time), let Windows installing the drivers (checked in Device Manager), then restarted the PC, and ran Smart Switch again. I repeated the procedure of loading Emergency and Initialization, entering the model and serial number, having it fully downloading the firmware (again) from the web, and installing the firmware into the device. This time it completed the process, and I finally had the device installing and booting into a fresh version 6.0.1 of Android!
Hope it helps!
History:
I have a samsung tab S6 lite LTE version. The tablet freezed out of nowhere when I was working and restarted but stuck in bootloader. After a while, and after removing the sd card, the tablet functioned properly. The tablet had more 80% of battery charge.
I thought the new update might fix the issue. I installed the update. it restarted and stuck in bootloader again. Power and Volume Down buttons will restart the tab, but it never went past the bootloop.
Left it for 12 hours without charging, and then the tablet went into recovery mode. I wiped the cache and when figuring out the other options in recovery it switched off and did nothing. When connected to a charger, a circle with lighting icon showed up. No combination of buttons worked.
Took it to the service center, and was told the motherboard needs to be replaced. I knew it was a software problem so I came home without replacing the motherboard.
I put the tablet on charge for a while and pressed volume up and down button and connected it to the computer. The tablet went into download mode. I immediately downloaded Odin and stock firmware and tried to flash only the BL file to the tablet. It failed few times, maybe because of faulty cable. I used another working cable and tried to flash the full firmware and the tablet disconnected again from the pc.
But now the tablet showed "an error occured while updating and use smart switch for emergency recovery". Smart switch on pc did not detect the tablet, but Odin did. The device manager detected the device as samsung mobile usb composite device. I used a new usb cable and flashed the stock firmware using Odin. The process was success but the tablet died.
It does nothing when connected to a charger or pc. No display and no buttons worked.
I opened the tablet by removing the display, and disconnected the battery physically. But nothing happened.
I tried several times to connect to pc, and for once it was detected by the pc.
This time I flashed the stock firmware using odin with nand erase and repartition. extracted the pit from csc file and added it to Odin.
The flash was a success but the tablet remains unresponsive. I checked the display to see if I had cracked or damaged it while opening, but it is good.
Now Sometimes, the tablet gets detected by pc as samsung mobile usb composite device and I could even flash the firmware with success. But the tablet displays nothing and is unresponsive.
Can Anybody advice What I can do now?
PS. I used the correct firmware meant for s6 lite LTE version every time I flashed.
Disconnect devices from PC USB port & uninstall official Samsung USB drivers. Reboot & re-install drivers. Connect to another USB port preferably at the rear PC.
Flashed latest Android 10 instead of the latest Android 11 stock firmware (AP *super.img.tar file ONLY) using Odin (I used official Odin3_v3.14.4) with Auto-Reboot, Nand Erase and Re-Partition. Input *.pit file. Flashing process might take 'years' but be patient until it ended & auto boot up successfully. Try another USB port if it failed. Therafter, flash the rest of stock WITHOUT Nand Erase & ONLY Re-Partition, Auto Reboot & F. Reset Time.
Once it successfully got flashed & auto reboot, wait patiently as it might also take a longer time than normal to boot up. Charge the device to optimal. Done!
Optional (Remove Knox Guard)
Connect to the internet. Login to your Google & Samsung account to update everything & reboot upon further updates. Thereafter, boot to Download Mode & flashed AP (Magisk Patched *boot.img, blank *vbmeta.img & patched *vbmeta_samsung.img) + BL (Blank *vbmeta.img) WITHOUT Nand Erase & Re-Partition. After successful boot up, reboot back to Download Mode & ensure there's no 'KG State' on the list before deleting('root delete' not ADB) Knox Guard or app named Payment Service as in Android 10.
Thanks. I will try.

By chance is it going to work for KG:Locked status device? I'm on F62, i bought this (second hand) few days ago from another city. Tapping on build number doesn't give any response, When i try to flash any firmware I'm getting response "All binaries are not allowed to be flashed" I'm pretty much confused what's happening here
