Bricked the Onn 100003561 - Walmart Onn Tablets General

I bricked it and adb wont dectect it on adb, i tried to flash the magisx rom on it and then it just didnt make it past the boot screen and gives me the orange state error, ive tried everything but its still not dectected by the adb thingie

just use the preloader, get mtk-client and then plug it in with power off. Sometime you hold volume up/down same time.

Get the mtk-client from GitHub, turn it off, sometimes you hold just the volume buttons and sometimes just plugging it in. The preloader only works when it is off.

it died and it turned into a paperweight and i cant turn it back on and i charged it for a while

You have to get the preloader to start. Also it is very touchy as far as how you get to it. You should at least get a error when you try mtk client and we can worth threw that.

I just bricked my kid's old one, but finally reflashed it. sp flash hands on the preloader part of the "shipping" image I found, but the newer "100003561_12-17-2020_Firmware" flashed & I got it running again. seems like it's preventing the downgrade. *sigh*
my biggest issue was getting the preloader drivers installed. finally found this file "Windows 10 MTK VCOM USB Preloader Drivers" to work on this hand build 2016 PC running a ryzen 1600x (LoL total dino) running Windows 11. found a youtube video, (sorry if this links not allowed but it helped me, please remove if this violates any rules)
but I didn't actually have to remove the battery ever. just has to let it set about 10ish (try counting to 30? LoL) seconds before connecting. basically...
get drivers installed
get stock rom downloaded & extracted
get sp flash installed
get sp flash ready (*open, *load generic d-a bin file, *load the scatter from the stock image)
then while holding vol-, connecting the usb-c cable from tablet to PC
sp flash then starts doing its magic, ends with a yellow bar, & a big @$$ green check mark
then I got back to this (LoL top secret) Chinese menu, vol- to last item, hit PWR to select (reboot cellphone) & then watch this onn. logo for what feels like days as it comes back up wiped clean as a baby's bottom
hope this helps

F'd up my vibrant i could use some help!!

hi guys... so i don't know how i got this vibrant soooooo far gone .. im afraid i have gotten it too far...

omg!!! so im freaking out.. anyone know if there is a way back from this?? i can't even get back into recovery mode!!
please any help will do......
there was a thread about that issue, turn off your phone, unplug the usb cord, plug the usb cord. hold vol up and vol down and the power button. it will come on but when it goes off release the power button and keep holding down the vol up and vol down. should go into auto download mode. then u can reload it via odin.

this is normal just continue to download mode as normal.
http://forum.xda-developers.com/showthread.php?t=741027
you can save your device through odin, plug your phone in to your computer and try to go into download mode may take a couple tries, and flash the stock ROM you can find on these forums
i have already tried the sequence to get it into download mode... it doesnt work... tried adb and nothing registers....
anymore ideas? looks like im going to have to do a warranty exchange.
The only way I can reliably get to download mode is: power off, remove battery, replace battery, hold both vol buttons, plug in usb. works every time though.

ok so that actually worked!!!! i pulled the battery ... pluged the usb cable in and while holding volume up and down buttons i forced the battery in.. and now its in download mode!!!!
now here is my next road block.. whenever i tried to use odin i cant get pass that file analysis part and nothing happens..
any ideas? i looked it a thread and it said to reboot my computer into safe mode and disable digital driver sig.. still not working..
ideas on how to get pass the file analysis part?
Best way for us to help you, is for you to help yourself first, educate yourself and post this in the right forum please and we would all be more than gracious to help you out

are you using a .pit file? and if so is it the right 512 .pit file?
if both those are yes, delete the one on your system and re-download it.
I had this same exact problem a few weeks back Odin would hang on the pit file, just redownloaded and it worked like a charm.
and just a quick reminder of everything out for the Vibrant right now
Only stock firmware use the 'PDA' option a pit file, and re-partition
froyo firmware use the 'PDA' option and a pit file, no re-partition
JACs kernels use the 'CSC' option and no pit file, no-repartition
i have a Bell Vibrant and all the methods don't work. i tried the 3 button (remove batt,place in batt, plug USB, wait for the the ''star" to appear, hold VOL+/- and POWER and wait for the screen to turn off, release POWER, but it just goes back to recharging screen. tried it 40 times
tried the power off, remove battery, replace battery, hold both vol buttons, plug in usb. no go as well.
ANything else? I'm stuck at the boot screen (the 'S' glowing part).
This is what always works for me.
Unplug your USB from your phone
Makes sure ODIN is ready to go on your PC
Hold down the Down Volume and Power until the download screen comes on
Then plug your USB back into the phone
fire up odin
pull your battery
connect phone to pc WITH THE BATTERY OUT
hold volume up+down and power
put battery in while still holding those buttons
the screen will light up with....something. Wait for the screen to blink and then release the buttons.
You are now in download mode!
i will try those methods. Thanks.
crap, still no. just keeps showing the battery charging. i remember rescuing my htc magic so many times, but no go on this guy.....
Odin all fired up when doing this......

Did you make sure that the USB was unplugged when you used my method of holding down the volume down button and power button together until the download screen came up?
If you are familiar with ADB. You can also power your phone on and then plug in the USB and then type in the command line:
adb reboot download
to get it to reboot into download mode.
You can also use this command from the recovery console if you are able to get to it.

Dude, the Vibrant is new to us all. None like it. So dev wise its harder to explain and understand when we are used to coming from a one press method, now were using Odin, and Thor's hammer to flash our phones, which is god awful, no pun intended.
Dont flame your fellow Vibrant user cause he doesent understand the 613 steps it involves, and every other way to do so. Help the kid.
I am also in this position, just using a finger in the socket method, if its on it'l shock me, know what i mean. Just try it all. I have a feeling its getting harder and harder to brick phones because the manufacture is not retarded, they fix them right back, and ship them back out to customers who need replacements. I know this as a friend works at an AT&T shipping warehouse.
So cant we all just hit a bong, or get a long? And help?
If someone could explain all this 512PIT, PDA, and CSC, and Phone. It would help so much, sometimes a picture is worth a thousand words. Just sayin.

Yeah man, i'll try it again!! And when do I start typing (sending out the adb command) when the power turns on? Thanks.
Question is: when i press power+vol Down, the boot splashscreen comes on (Galaxy S etc etc).....
I am sorry you have a Bell Vibrant, it is a little different than my phone. I found this hope this helps
HOWTO GET INTO DOWNLOAD-MODE:
- Turn off your Phone
- Hold VOLUME DOWN + HOME Buttons
- While holding VOLUME DOWN + HOME Buttons press POWER Button until you reach Download-Mode
- Release all Buttons
I also read that some of the Bell Vibrants had their Download/Recovery mode disabled.
http://forum.xda-developers.com/showthread.php?t=754673&highlight=bell
As far as the adb command I would start as soon as it powers on. It will say "error:device not found" at first, but just keep on hitting arrow up and hitting the enter in the command window until it accepts the command.
Good Luck

[Q] Nexus 7 bricked on laying robot with red exclamation mark

Right... I spent the last 6 hours reading through the forum and Googling about this problem. I learnt a lot (!), but cannot solve the problem, and I now hope someone can help me
Sorry for the lenghty post, but there's a lot of information to share...
Yesterday, my long-awaited Nexus 7 (8Gb) finally arrived. It worked just fine for an hour or so: I got online without any issue, Calendar, Photos, GMail and Contacts were nicely synching and I was really starting to get impressed about the speed and features.
I did download a couple apps, more specifically Aldiko & Moon+ Reader ebook reader apps, and Facebook).
Suddenly --I believe I just started the Facebook app-- the screen turned black and showed strange stripes. The device rebooted and got stuck on the black screen with the white "Google" text. I let it sit there for a while and then instinctively tried to power-off the device by holding the power button for 10 seconds or so. It did indeed reboot, but when the tablet booted up, it popped back to the black Google screen and just sat there.
FYI: The USB cable was connected all of the time, and the first time I plugged the Nexus in, my Win 7 64bit machine recognized the tablet and loaded the drivers for it.
When it got stuck, I decided to continue charging it, thinking that maybe the battery wasn't fully charged and the cause of the problem. I hooked it up to the official charger in a wall socket and let it sit there for a while, while I started searching the web for a solution. After about 30 minutes, when I had read about the power+volume button combination, I tried this combination (until then the Google page showed for more than 30 minutes). The Nexus indeed showed the Fastboot screen, and I had to plug it back in the PC's USB to get the buttons "start", "recovery mode", "power off" and "restart bootloader" working. None of them had any effect.
The fastboot screen showed the product name "grouper", the lock state as "locked"; the bootloader as version 3.34 and the HW version as ER3.
I downloaded the "Nexus root toolkit" from WugFresh and tried to flash it back to "stock" with Android 4.1.1 JRO03D. The tool did show my serial number, btw.... Until then, I had good hopes, but then it went wrong: the tool downloaded the files, unpacked them and said something about "wiping flash" and everything froze. After about 20 minutes, I concluded it had locked-up and unplugged the device.
It now seems to be completely "bricked"...
I can no longer get to the fastboot screen; Not even with the 3-button trick... it always shows the Google screen and immediately shows the "dead robot" screen with the exclamation mark.
The Nexus does not start up Android, so I cannot activate ADB/ USB debugging...
The device is no longer recognized by my PC; the PC doesn't make the "USB hooked up/disconnected" sound anymore
I tried uninstalling the drivers and installed the "naked drivers", no solution -- they show up with yellow exclamation marks
I installed the SDK, and "fastboot.exe devices" shows nothing
I downloaded the "Nexus 7 Toolkit 2.0"; I cannot access the tablet, no serials show, drivers cannot be installed
FYI: I did not try to root it or unlock it. I rebooted my PC, I power-cycled the Nexus, I changed USB ports, sigh...
I'm afraid I actually bricked my device... If so indeed, and given the fact that I cannot access the device with any of the tools/toolkits, is there anything I can do to put it back to factory settings?
Someone else may chime in with some help, but I think using the toolkit screwed you. Had you just used fastboot while you had the bootloader up you could have reflashed the stock rom yourself using the file from here and these commands.. but since you can't get into the bootloader now I think its hosed, but I could be wrong though.
I just noticed that when I press the power + volume up button, my PC detects it as an "Asus Transformer Prime APX Interface"?
Would this be another "way in"? (found something about NVflash on Google?)
Here are two threads on the topic, however I don't think they restore it that way since mostly its done thru the bootloader
http://forum.xda-developers.com/showthread.php?t=1879228
http://forum.xda-developers.com/showthread.php?t=1882753
and people still continue to use toolkits because its easier. in reality its just easier to mess upon your device. reading through the forums i have yet to see someone that messed up their device with fastboot oem unlock amd fastboot flash recovery recovery.img.
To be honest; I feel the toolkits are great for people that know what they're doing and understand the process and are just looking for a quick way to do it.
People that are new to the rooting scene and don't understand the process are the people that SHOULDN'T be using these toolkits. They need to learn about the process and do it a few times manually before even attempting the toolkits.
OK guys, I got the message and yep, shouldn't have used the toolkit. **guilty** :cyclops:
But what advise do you guys have? Would the APX/NVFlash path make sense?
Or can you advise how to get support from Google/Asus in Belgium (bought tablet in Staples US )
thanks!
Considering it doesn't seem anyone has used NVFlash to restore it looks like you are going to have to return/exchange/RMA whatever option is available to you, unless its figured out
i see you pressing volume up and down and power button to get into the bootloader.. but thats wrong. its power button + volume down to get into the bootloader(maybe thatll make a difference for you). but yea, chances are that youll need to go for an exchange/repair.
Nvflash should work though. I haven't used it since.my last tablet and.unfortunately I forget how to use it. I don't think zip files can be used. I think someone could help him that knows how to set up a folder of files for nvflash.

Dont think you can flash those files thru recovery, I already posted that link for him unfortunately without the bootloader I think hes hosed
In order to use these files, you need to have the fastboot tool in your PATH. That tool is compiled as part of every configuration of the Android Open-Source Project and is the tool used to flash custom builds on your device. On GNU/Linux systems, this also implies that you have configured USB access as mentioned in the machine setup instructions.
Your device needs to be in fastboot mode, with the bootloader unlocked. The relevant key combinations and commands are documented on the page about building for devices.

A20e stuck in download mode

Hi,
I have a new a20e (a202f) out of the box.
I followed another guide to root and install twrp which turns out was wrong. I unlocked the bootloader just fine.
I have no backup, no personal boot.img or anything.
Essentially I am stuck in download mode and restarting takes me straight back to download mode.
Recovery: Error validating footer.

Cheers guys
What guide did you follow? You have to download your stock fw from sites like sammobile then from there you can have the boot.img and etc. Have you tried flashing stock fw using odin?
Note: Usually you flash vbmeta for footer error when you flash twrp.

It was a guide on 'unofficialtwrp.com' - I can't link things here yet.
I have since tar'ed an unpatched twrp (TWRP-3.3.1.0_A20_by_Agrim720.img) + vbmeta.img + boot.img (from https://forum.xda-developers.com/galaxy-a20/help/boo-img-a205fxxu2asfb-t4008739), then I flashed through AP on Odin and now I think it boots past the download mode but instead it now has fuzzy dark red screen with nothing legible.
Oh bugger, I've been a class A plum.
Can I get out of this horrible mess?

Well you have to use your own boot.img from your fw, not all of use the same fw that's why, some are still on u2, u3 and u4. Maybe the boot.img you got isnt the same as your fw.
Well you can start from scratch and reflash your stock fw in odin.

Try holding volume - and power and your phone will turn off, as soon as it turns off press volume + & - and plug your usb cable that is connected to a computer.
No luck with that. It displays the message about running custom os etc and to press power to continue. So I press it and it boots to the messed up red/pink/black display.

Yes that screen. I've tried your suggestion with volume + but that also ends up with messed up screen
Yes so currently I'm unable to get to recovery (not sure it even flashed properly), unable to get to download mode, or to get the device recognised in odin.
I'm unable to power off. The screen is blank and when I press power it flickers shortly with some black/white/red pink colours around the edges, but the screen quickly turns blank.
From this position I can only restart by holding volume - and power.
This boots to the samsung logo and then the 'bootloader unlocked' warning. No amount of button configs have proved successful so far, and then I end up back at the blank screen.
I'm happy to start from scratch. I have downloaded the stock firmware but I'm simply unable to proceed.
Aslo the device is not recognised in windows at any point.
Thanks guys

Are you sure you pressed and hold volume +&- and plugging cable before the samsung logo pops up? You have to do it quickly right after the device turns off. You shoudn't see the bootloader warning if you done this quickly and correctly.

Hello -
Please trust me when I tell you that it can be fixed. I had the EXACT same problem and drove me crazy for 24 hours. You can deffinetly fix your phone once you get to download mode.
I had the same issue where I could not turn the phone OFF it just looped back and I pushed buttons for hours to no avail... Then some one told me it WILL WORK, it is just the timing of
the button pushing, AND the USB cable plug in. Sure enough he was right. It took me alot of tries and I even took my phone apart and un plugged the battery so I could controll the power
ON / OFF better and time the button's easier. Here is what I did ...
unplug battery so phone was 100% OFF.
Plug in battery ( phone is still OFF )
Hold Vol - then Hold Power and Vol -
As soon as the power started IMEDITALY PLUG IN USB ( have USB READY to be plugged in FAST )
DONT let go of buttons ... screen will flash quickly and then Imediatly let go of power keep holding Vol -
IF you timed this right, IT WILL proced to download mode. If not, then start over again from power OFF ( step 01 )
It took me 3 tries to get it ( after 50+ tries before ) lol
Now I am not sure about the battery unplugging ... maybe you dont need to, but it mad it work for me as I could control the power ON part of this now.
Getting to your battery is not very hard and there is a you tube video on how to do it... if you need help just PM ME.
Good luck friend.
When this happened to me all I did was hold volume up and volume down. Kept cord connected to computer. Connected to device during the bootloop and boom within seconds I was in download mode. It catches it once screen goes off in between the bootloop.
Sent from my SM-N950U using Tapatalk
Thanks you guys. In the end the battery died and then I could power up whilst holding vol+, straight to recovery and then I could flash stock rom.
Much appreciation for your help guys, it got me out of a pinch - it is my mother-in-law's new phone!

Cannot unbrick [cannot enter EDL mode]

Hoping someone can shed some light. Rushing to root phone again to send back warranty replacement, in my haste my laptop died mid flash and now can only boot in Fastboot and Crashdump Mode.
I am attempting to restore to factory via the MSM tool but cannot for the life of me enter EDL mode.
With phone powered off and pressing the vol up and down keys while plugging into the PC, it only enters Fastboot mode
I have tried to do it with phone off, rebooting from Crashdump mode, from fastboot and it seems that no combination allows me to do so.
I have also tried just vol up and vol down. App loaded at the flash screen, not loaded, etc.
Thanks in advance

What I did when I was in Crash Dump Mode was,
Press and Hold Power Off and Volume Up button and release when the screen goes off. Now your phone is switched off. Now to enter the EDL mode you need to press and hold volume up and volume down buttons at the same time...and then connect the mobile to pc while still holding the buttons. Done. MSM tool will detect your phone.
NOTE : Also keep the Device Manager window open on the PC while u connect the phone to pc and check if it shows up there.

It always seems to take me several tries to get it right. I think if I don't hit the vol +/- keys right at the exact time that's the problem. Just be patient and keep trying. The first time I did it, it took me what seemed forever. Thought maybe my phone was broken.

I have been doing custom roms since the old win ce devices....and yet you sir have been able to make me feel like an idiot haha. Thanks for this. you had it spot on!! thanks so much
Hello Folks. So i have found myself in this situation as well. MY phone wont go off and keeps restarting to CrashDump Mode. As such can't seem to get into EDL mode inorder to flash. Any tips? I have tried all the above methods nothing seems to work. Is there a different key combination or a fastboot command i can use to achieve EDL? Help a brother i'm going nuts. Device IN2020

You just need to keep trying it. Make sure you hit vol+/- at the same time and hold for a few seconds, plug in the USB cable, then let off the vol keys. It's difficult to do and get right with two hands. Recently did it again as I wanted to upgrade to the 11 beta from a clean system. Seems like it took me forever to get it this time but eventually I did.
Use usb 2.0 port.
After using 2.0 instead of 3.0 and the phone connected stable for a while (after many tries)
able to finish the msm operation successful ..
But phone not booting .. getting black screen after 1+ logo
at this point I thought to clear cache but My phone is locked I cannot use any recovery .. I cannot even go into oneplu recovery LOL .. It seems like I am doomed
For me personally I could only get it to work on USB2.0 ports. On USB3.0 it just puts me back into fastboot mode or when it does go into EDL MSM tool just fails with a communication error immediately.
I kinda bricked mine as well messing around with GSI ROM's and flashing too hastily and to the wrong partition lol.
It has always worked for me with USB 2.0 port and non oneplus cable.
originable cable would not work for me on usb 3 or USB 2 port, but 3rd party cable start immediately with USB 2 port.
I've had the issue where EDL mode works..... for a few seconds, then the phone reboots.
Very frustrating!
The MSM Download Tool does spot the phone, but since the phone seems to reboot, I don't have enough time to do anything!
Any ideas why this is happening?

You need to already hit start on msmtool BEFORE plugging in phone
1- start MSM tool (prepare the settings and choose the right oos)
2-keep the cable connected to one end (I prefere to keep it connected from the phone side first)
3-keep holding volume up/down for 3-4 sec and connect the other end of the cable to your PC
4-your device will be connected directly stop holding volume up/down and in msm tool press start wait for ≈300 sec
5-now your device should work as it was before

After rebooting my pc, and fiddling with drivers, I got it all sorted finally.
Thanks for your help, folks.

What I did when I was in Crash Dump Mode was,
Press and Hold Power Off and Volume Up button and release when the screen goes off. Now your phone is switched off. Now to enter the EDL mode you need to press and hold volume up and volume down buttons at the same time...and then connect the mobile to pc while still holding the buttons. Done. MSM tool will detect your phone.
NOTE : Also keep the Device Manager window open on the PC while u connect the phone to pc and check if it shows up there.

This is a royal pita! I remember when it used to be fun....
Anyway, I've been trying every trick in the book, and then some, but shiznit just isn't going right! The holding of the up and down buttons would be easier if this was the pixel, but it is a tad hard to not mistakenly hit the power button on the other side.
The device manager shows the Qualcomm QDLoader and the msm Downloader is showing the infamous waiting for device... I've been at it for 8 straight hours and if there was a local OnePlus store that sold the international version of the OP8P, that's where I would be heading in a few hours.... It's really frustrating to say the least.
Anyway, when I'm in the bootloader, the device manager shows the Android phone, so I'm thinking that maybe I am in the edl mode when the Qualcomm port shows up, but like I said, the msm is waiting....
tried everything and it is constantly booting into bootloader. I even tried an adjusted fastboot script to boot into EDL but it still boots into bootloader. I have booted into EDL before on a OnePlus 7T, and I have tried multiple times by pressing the OnePlus 8 pro volume buttons at the same time, but always bootloader. Just to check, I tried doing it on my OP 7T again and it worked perfectly fine. Help????
I have had to flash stock 4 times because I land in crash dump mode and it has always been a tricky situation to get into edl.
What worked for me 100% of the time was following the steps in the youtube guide below.
From 2:30 onwards
Hope it helps
I had the same issues, but fixed once read comments as per above. Let me summarize what I did:
1. installed driver Qualcomm HS-USB QDLoader 9008 (I'm using Windows 10) - driver in a cab file should be unpacked using command expand (with proper switches) to preserve folders.
2. launched MSM DT and had it configured and then pressed Verify\Start, as EDL is available only for very short time - 2-3 secs with screen turned off.
3. as my phone was stuck in booting loop I was just keeping presses Vol+/- waiting for EDL to be entered, MDM will find the phone and start uploading data.
Just don't give up trying.

Hoping someone can shed some light. Rushing to root phone again to send back warranty replacement, in my haste my laptop died mid flash and now can only boot in Fastboot and Crashdump Mode.
I am attempting to restore to factory via the MSM tool but cannot for the life of me enter EDL mode.
With phone powered off and pressing the vol up and down keys while plugging into the PC, it only enters Fastboot mode
I have tried to do it with phone off, rebooting from Crashdump mode, from fastboot and it seems that no combination allows me to do so.
I have also tried just vol up and vol down. App loaded at the flash screen, not loaded, etc.
Thanks in advance

Try different ports. My usb 3 port would force it into fastboot but usb 2 was fine.
What to do if the device doesn't have any usb 2.0 port?

Having some big problems - Need help please!!!!!

I got a replacement device from OP and I was unlocking the bootloader and rooting it. The guide i used had the incorrect patched boot image and everything went bad quick.
I can't go anywhere except fastboot now, can't boot to OS, no OS installed.
TWRP WAS booting from fastboot, I pushed the rom from there and flashed it...said no OS installed after, I installed it on both slots.
I can't get into EDL mode, the volume keys work...I think, but the second I let go of them when it's plugged in it defaults back to fastboot immediately. I tried the bat file that people use, says it worked, phone stays in fastboot.
I even tried holding the volume keys the entire time but the MSM tool wouldn't read it enough to flash anything, although it did read it enough to register some data, but was stuck on "waiting for device".
I am in need of some major help. Now I can't even temp boot to twrp, getting an error failed authorization. I'm afraid I really messed things up.
I have 5 days to send my old device back. Please help!
May be a longshot, but does the stock recovery work? Maybe try sideloading the full OTA zip from there?

For EDL mode, you need to hold the buttons then plug it in while continuing to hold the buttons. It won't work if the phone is already plugged into a usb port and then you try and get into EDL.
Really hard to brick a OnePlus device in my experience.

Recovery doesn't work. I was able to get to one of the steps to approve going into fastboot, advanced, reboot to fastboot, but not anymore.

I was doing just that. It seemed to work initially but after I plugged it in and released the buttons it went back to fastboot and disconnected from MSM.
Make sure MSM is ready keep vol up/down pressed, connect cable and immediately press Start in the tool. Have done it like this 3-4 times with my Pro
Please read this https://forum.xda-developers.com/showpost.php?p=82508527&postcount=67
and this https://forum.xda-developers.com/showpost.php?p=82658631&postcount=85
both work for me.

I ended up using the fastboot ROM flash all.bat from this thread: https://forum.xda-developers.com/oneplus-8-pro/how-to/rom-stock-fastboot-roms-oneplus-8-pro-t4083997
I am now booting into the OS and the stock recovery came back. So good news is the phone isn't bricked.
Glad you sort it out
