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!
bought this phone used and I don't think it was rooted but never checked, confirmed. Last night it turned off and will not turn on anymore..
Tried the pwr button for several minutes and no change. Plugged it in with several different cables and no change.
Any other suggestions or options? USB to computer detects something but says it can't install the driver.
Any ideas?

Can you enter to the bootloader menu? Maybe you can enter recovery and wipe the cache and dalvik

negative, either the phone is totally dead or the screen is dead but NOTHING happens when pwr is pressed
here is what I have tried:
1. Press and hold PWR button for over 3minutes
- Plugged in and unplugged into ac - no change
2. Press and hold volume DOWN + Pwr for over 3minutes
- Plugged in and unplugged into ac - no change
3. Plugged into different a/c power outlets with 2 different chargers - no change
NOT sure what else to try or do?
Funny thing is if ya plug into a computer it does indeed detect "something'
However it says it can't load the USB drivers something about QU_***
Open to any ideas and suggestions.. WHILE I would love to get the phone working whats more high priority for me now is the 20gb's of pics that apparently did NOT back up.

Funny thing is- that "something" is the solution to your problem. Capture the error message completely and search the 6P forums for that. Several threads on the "something" issue.

fixed that issue, aka QHSUSB_BULK is now working properly according to Device Manager.. but Nexus 6P is not detected, and doesn't even show up in Disk Management either.
Any other ideas?

If you found the right EDL_9008 thread, there is Qualcomm software to download for your PC. If your phone is in the right downloader mode you can use the PC software with a special recovery.img. I don't know anything about it, just read through the threads long ago. It's a mixed bag with some success stories, some not. Keep looking though, I think you are on the right track. The original poster was "Tenfar" if I recall correctly. Good luck.
Try cleaning out the charging port.
Hi there,
I think we are in the same/similar boat. My phone shut off while using it (screen froze, then went black) and seems to have bricked itself. I *am* able to get mine to turn on, but only about once per day after it has been left plugged in for a few hours (although there is no indication it is charging while plugged in - never gets warm, no lights, etc.) I can get into recovery if I am lucky (usually get to the android bot laying on its back, then PWR+VOLUP just causes the phone to shut off instead of actually getting into recovery menu.) I've been able to clear cache/factory wipe from recovery menu with no luck. I never did unlock the bootloader so I am unable to use fastboot to do anything. I tried to flash a few OTA (full and incremental) images using adb when I am able to get into recovery, but they always failed in one way or another.
I've been trying the methods described in the 'tenfar' threads - using the xiaomi flasher and QPST tools. The xiaomi tool always fails for me. I have been able to get the QFIL tool to successfully 'download' about 3 times now, with tenfar's recovery images. However, after the success message, the phone doesn't do anything (I read in other threads it should reboot itself) - and after unplugging, the behavior of the device seems to be the same - just stuck and won't turn on at all.
Right now I think I am stuck in 'EDL' mode where the only evidence that the device isn't completely dead is that it shows up in device manager as 'Qualcomm HS-USB QDLoader 9008 (COM3)', and the factory imager tools do recognize it.
It *seems* like the only way forward is to somehow get one of these factory tools to flash the right set of files onto the device - I've tried a few now with no luck. I even tried extracting the relevant *.img files out of the google factory image download and replacing tenfar's image files with them. I was able to load those onto the device with QFIL. This morning my attempt at turning on the device has me stuck on the white google logo, which is new behavior for me - usually it shows the logo for ~5-10 seconds then the device powers off. I've left it on for a while stuck on the white google image, but I'm not sure if I'm doing anything useful here.
Here are my reference threads:
tenfar's 'debrick' thread
QFIL thread
If anyone has any crazy ideas, I am open to try them. Thank you.
Maybe disable big cores?

I have the 100% same issue. Screen froze,then went black and now its stuck in EDL mode. I need my data. Recovery access or anything else would be fine/enough for me. I have had LineageOS and TWRP on the device. With TWRP i can access my data.
How have you got your device on? Mine dont start once a day or so. Its always in EDL mode ( 9008 ).

Sorry bud - I never was able to get any further than when I posted this. I eventually gave up, got a full out of warranty refund through my CC after the manufacturer wouldn't help me at all, and upgraded to a Pixel XL. I still do have the device, I should try to boot it up again . I didn't have any data concerns on my device so I was able to give up... good luck!
Hey guys,
Guess today it was my turn ****ing up.
I apparently have completely bricked my Axon 7 after trying to go from LOS 15.1 to stock oreo beta. The only thing I seem to be able to boot to is DFU mode and for some reason, if I press the Power button + Vol Down I will get stuck on the ZTE Logo and my PC will detect my phone through the ADB interface but every time I try doing something it says my device is unauthorized. Is there any way I can authorize the device whilst being completely bricked?
The only other thing I get is the unlocked bootloader warning screen. If I don't press anything the phone will be stuck there, if I select recovery the phone will simply shut down and anything else will result in a reboot. I have also tried a deep flash cable that that only results on the phone being stuck at the unlocked bootloader screen.
I cannot access the bootloader,
I cannot access EDL mode
I can access ADB, but device shows as unauthorized.
I can access DFU mode.
Any suggestions would be appreciated. I have looked at the Hard brick guide that involves taking the phone apart but that's not something I really want to do.
Thanks in advance.
Edit: My phone gets detected by MiFlash but every time I try flashing I get a cannot receive hello packet and object reference not set to an instance of an object.
ZTE axon 7 EDL tool detects it in ADB mode but says ERROR! NO ANSWER FROM PHONE!. Possibly since its not authorized with ADB.
Ouh....DFU? I think this thing is totally bricked.
I can access my phone in ADB. If only I could make it reboot to edl or something like that through ADB even though my device shows as unauthorized. That is the only problem why this thing is completely messed up.. ADB works but I can't do anything with it because my phone shows unauthorized. Does anyone know if there's a workround or a bypass for that?

Hi Victor !
Like we discussed before there is nothing much left as to use the DFU unbrick-disassemble guide or buy something like this to be sure you tried everything.
Good Luck mate !

Thank you for your help . It's a risk you take when flashing phones.
Can you get custom recovery in it some recovery allow you to get in to EDM from there you can flash stock rom with Mi flash tool.......try to push both volume buttons at the same time don't touch the power button this might get you in to EDM.

Nothing, you'll have to use my guide for that (the one that raystef linked). Otherwise try entering FTM mode (Power and Vol-) but it's surely not gonna work. If it does, you'll see a screen with a square that says "FTM", and you'll be able to do " adb reboot edl" and flash stuff from there.
Unbricking by disassembing the phone is the most reliable method; an EDL cable just might save you the hassle but it's not guaranteed to work; some phones won't accept it for some reason. In this case just follow the guide unless you want to try your luck with an EDL cable

Hello. Thank you for your advices, it is as I feared.
I have however already bought another Axon 7 which I'm using at the moment, and I have plans for mine since it was only bought new about 8 months ago and I believe I could get a replacement for a fee even if its bricked to fault of my own. So I will try that since I'm not in a rush.
This thread can be closed.
Cheers!

In that case you can just pretend that the phone got in that state by itself, it's not too morally correct but some people here pulled it off...
twice now i have gotten an axon 7 into this state. while mine have been a2017u models, i dont know that they are different than yours in that regard.
What worked for me the first time was letting the phone completely die. Being unable to boot into anything, it was somewhat a task to actually make it die, so i kept powering it on (which merely made the red led indicator come on). i did this over and over again over the course of a day at work whenever i noticed it had powered off.
eventually, the phone had no response at all. then, i plugged it up to my laptop, and left it, convinced i had killed it. a dialogue popped up after a minute or two on the phone screen saying to charge the phone by plugging it up. i had no access to fastboot or EDL mode prior. once i got that 'plug in to charge' screen, i switched it to the wall charger, and left it to charge a bit (50-60%) from that state, then, i unplugged it again, and somehow, i managed to get edl mode to work by unplugging it and pressing all three buttons and holding them (typical edl boot).
once there, i reflashed via MiFlash an earlier build. i rolled back using MiFlash as far back as i could. in the process, i lost my imei and serial, which i have yet to successfully recover, but i did get out of DFU pergatory. the imei thing seems to be caused by going back to MM which i did on both of my IMEI-less a2017u boards, but im only guessing. my dd axon 7 is the only one of the three boards with imei and serial, so maybe MM is a bad idea. lol.
The first time i recovered from DFU, i did it inadvertently by letting the phone die and then flashing in EDL mode as well. (i left it for a few weeks as i had given up on it.) after it died completely, and i plugged ut up to the computer and had the same experience, I flashed the beta oreo build for a2017 using miflash. the screen had stopped responding. and i ended up doing a RMA. I now know the screen response thing was bc of a faulty EDL file of B15. (happened again to another of my axon, so i retraced my steps and realized it was when i flashed b15 that it died) . the fix if your screen ever stops responding, but isnt physically damaged? re-flash via EDL a different file. it may take a few tries, but eventually a build will work. for me, it was Marshmallow. I still do not know for certain, but that possibly is what killed my IMEI. but hey, it boots and the screen works.
I genuinely hope posting my idiocy in toying with axon 7s has helped someone out there.
I have a redmi note 4 mediatek variant and it's been stuck in bootloop for the past 2 days. It keeps restarting and doesn't go into fastboot mode.
The bootloader is locked. It won't go into recovery or fastboot. Sometimes it turns on when holding the power button but then goes into a bootloop.
This was the message last displayed on the phone:
RED STATE
YOUR DEVICE HAS FAILED VERIFICATION AND MAY NOT WORK PROPERLY
YOUR DEVICE WILL BOOT IN 5 SECONDS
And then it shut down and hasn't responded since.
Going to a service center probably won't help since this is a chinese variant and I live in India. The service centers here are mostly useless.
All help is greatly appreciated.
You can always try to do test point. Download official rom file and flasher, make sure to install fastboot drivers. Take apart your phone and connect two golden contacts on the motherboard while plugging in USB cable connected to PC. The phone should boot up to bootloader and you should be able to flash rom.
Test points should look like this: http://en.miui.com/thread-646232-1-1.html (scroll down, there is one photo)

I somehow got it working by completely draining out the battery and then booting. It worked for a while normally (around 30 min) and then went into a bootloop again.
I have some previous threads on my Redmi 7A dead... but no one responded, some did but said I can't fix it, buy a new phone. I am not in a financial condition to buy a new phone. All I can do is fix this phone and continue using it till I get a new phone. But since 3 weeks I am not able to use my Redmi 7A. I was hopeless that this phone could be repaired or could be used again but I went through a few videos on YouTube and saw a ray of hope but still I was helpless I tried booting it into EDL mode using the test point method but nothing worked out. Please I NEED HELP to fix this phone. I have a brief description below of the timeline about how it
crashed, how it was in the service center, what happened after it.
Alright so,
At March 13, It was on AOD (I know it is not supported keep reading), running nusantra os latest version for (Mi-439 aka Redmi 7A, 8) which was last updated on Dec 4, 2022. So when It was on AOD I tried to unlock the phone and it froze. So I rebooted it abnormally. After it was booting it stuck on the Redmi logo but it wasn't going ahead, not showing the boot animation. So I tried to boot it in recovery mode, when it was booting in recovery mode the phone was just shutting down and trying to reboot itself again but it couldn't. So I tried to wipe everything using fastboot commands and the command which I used was -w. So after that instead of waiting at the redmi logo it was stuck in a bootloop, in fact booting in the bootloader (fastboot mode). So after that I lost hope and gave it to the nearby service center. Please note that the phone was turning on before giving it to the service center. After like one day I went there to check if it was done, they say that it's a hardware problem, they are not able to fix it, When I came home the phone didn't boot neither in the fastboot mode nor It was turning on. So I thought it's not charged so I charged it for 1.5 hours but still there was no sign of life. I asked them about the phone not turning on they told me that it's a hardware issue and hung up the phone, said I am in a hurry I will call you later. Till this day I received no call. So Now I am posting this because I see some hope of EDL mode. I even tried to boot it in the EDL mode but still it was neither booting in the EDL mode nor my computer is detecting my phone (I have all the drivers installed). Please help ASAP.

1. does the led light up when you charge it?
2. what does you pc device manager show when you plug it in? (do you hear the windows sound?)
try every button combination that is possible. i mean two buttons at the same time, three buttons, all buttons... and for about even up to 1 minute (because this brought my 7A back from just led light when charging to pc detected a usb device)
i can't reproduce your brick but i managed to debrick via edl mode once on a "complete dead" (only led lights up when charging) so i think you can do that too.
also as long as you work with the EDL Tool, deactivate your Firewall (and don't forget to activate it again) just so be sure.
3. are you trying to enter edl mode via adb terminal? i would say you have to open the back cover and enter edl mode via hardware bridge from edl point to ground.
and as far as i can remember you have to be really quick between "starting" (booting) edl mode on the phone and make the phone "accept" edl mode. i think i first made the hardware bridge and then pluged the usb in.
i will dig deeper again in the next few days so i can give you better info's
