[Q] factory standard stuck at boot - One (M7) Q&A, Help & Troubleshooting

someone on one of the pages on facebook asked if anyone could help, her phone was working fine then suddenly wasnt and stuck at this stage (see pic)
its a factory standard phone, not been rooted, not been bootloader unlocked and S-ON, how to get the phone working again

Well the first thing to try is a Factory Reset, if its been tried already the only other thing you can do is Unlock the bootloader. This will void the warranty if there is any and if the phone still doesn't boot after flashing a rom you won't be able to reyurn it under warranty so that should be considered before unlocking it.
In fact you could try flashing a firmware package before unlocking that may or may not fix it without unlocking the bootloader. Do you know how to use adb and fastboot?

i dont think unlocking the bootloader is an option, any simpler things to try first?

Flashing the firmware is about the only thing you can do. Not necessarily simpler than unlocking the boot loader and won't be a guaranteed solution depending what the actual problem is. But it won't effect the warranty in anyway.

Also Don't Forget unlocking the bootloader will completely erase the phone ...everything on it will be lost.
Boot to stock recovery from the bootloader
the screen will go black wait a few seconds and press volume up and tap power you should see the stock recovery menu
do a clear cache from their and see if it boots
if no go back to the same screen and choose factory reset ... this will erase the phone also but it might boot up afterwords

[Q] Atrix HD wont boot into anything...

My brother just got an atrix hd from a guy at work. The phone will not boot into normal, recovery, or anything else besides the AP Fastboot mode. in the AP fastboot screen the text says:
AP Fastboot Flash Mode (S)
10.9B(*) (sha-2e68372, 2012-11-17 23:3308)
eMMC info: size 8GB
Device is LOCKED, Status Code:0
Battery OK
Transfer Mode:
USB Connected
Fastboot Reason: Boot menu selected
From what my brother knows the guy had the phone in his lunchbox and when he got home from work and tried to turn it on this is what the phone was doing.
Is there something i can try or a way to flash a system image? I've rooted, unlocked the bootloader and installed custom roms on a variety of phones and im sure i can get this phone straightened out if i was just pointed in the right direction. Thanks for any and all the help! its greatly appreciated!!!

Well, firstly, you need to unlock its bootloader IMMEDIATELY then you can try other action (reflash stock roms, etc..). Using Myth Tools is recommended in the post above.
After unlocking bootloader, you can try to download stock firmware from here:
Then flash it with Myth Tools (recommend) or RSDLite
If you satisfy with stock one, just keep it and do further mods or you can flash custom recovery before flashing custom roms.
That's my recommendation but you need to do the FIRST step is Unlocking Bootloader right now
Hope it helps.

I can't even root it, the phone shuts off if disconnected from a charger. And even when on the charger it keeps boot looping.

The boot looping which you mean is going to the fastboot mode, right?
Did you try to enter bootmenu (turn off phone, hold both vol + and vol - then press press powermenu to turn on) and select "normal powerup"?
Can you tell me whether your phone has ATT logo on its screen's bottom?
Maybe flashing back to its correct original firmware by RSDLite can help to bring it back then we can root and unlock bootloader.
But we need to know exactly which is its original firmware before it stucks there.
I've got it fixed...turns out the battery was bad. So luckily I switched it out with an atrix HD with a broken screen we had and it booted right up so I rooted, unlocked the bootloader and flashed the stock logo and a custom ROM. All smiles now! Thanks for everyone's help!

Having a issue with bootlooping, I unlocked the bootloader. I tried to install stock firmware but the phone doesnt even get past the motorola symbol it justs goes blank that tries to boot again. I can get it in to fastboot though. Its ATT version, is there anyway I can fix it?
Did Myth complete the flashing process? Have you tried using RSD lite to flash stock?

think im bootlooped after changing a digitizer
Someone in a club that i am in ask if anyone fixed phones, I'm a hobbyist, but very good with hardware and worked on countless ipods, tablets, Iphones, you name it. Some of you guys are like GOD MODE ON but i get buy, and really was just trying to help someone. (i haven't even cashed her check) so i tell her hey 15 bucks a phone i'll change the glass if you buy the parts.. grrr my mistake. i got this atrix hd. all i did was change the digitizer and now it hangs at the at&T screen... i tried RSD and flashed successfully, i tried myth and flashed successfully. i have no idea whats wrong with this POS.. i can get in fast boot and recovery ok. Does this phone need a sim in for first boot? i'm loosing my mind, i can't help but wonder if it's the new chinese digitizer, I wish i could get a system log outta this thing to see how it's hanging up.... any help would be greatly appreciated.

What ROM was on there before you changed the digitizer? Have you tried flashing a custom recovery and a custom ROM?

There's a chance that it could be the digitizer. About a week ago I replaced my Dad's digitizer and I read a crap ton of reviews before purchasing the one I did. Of the bad ones, a few had people complaining about it not working, most were the top 10% of the screen wouldn't respond to touches (like swiping down the nonfiction drawer), and I saw a couple describing your situation.
If you never had a custom rom installed, were rooted, or had the bootloader unlocked before doing this, I doubt that there's anything you can flash that'll fix this. If the bootloader was unlocked before doing this and there was a custom rom installed on the phone, you might have to flash Philz CWM, format the internal sd, and change its mount point to /data/media then format it again. Not changing the internal sd mount point after flashing a fastboot when coming from custom 4.2+ roms causes bootloops.
This is the digitizer I used to fix my Dad's Atrix HD last week. He hasn't had a problem with it whatsoever. My Dad is an ass of the highest degree so I'd know with a loud angry voice if there was ANY minor issue with it.

Ok so there are multiple questions to answer here.
#1 i do not recall which rom was on the phone.. although it appears it was the lastest AT&T as RSD re-Flashed it with a pass. I suppose i should have checked but i've never ran in to this situation. I was just changing the glass out.... you remove about 16 screws, pop the glass out and put a new one it...
#2 the customer does not want the phone rooted or moded, just stock
#3 the bootloader is locked and mythtool instructions are saying you have to be in debugging mode to unlock.... thats not gonna happen cause it don't boot..
So does anyone know if this thing needs a sim for a first boot after an actuall battery pull?
Also..
I unplugged the digitizer and tried to boot thinking hey other phones will boot without the digitizer, but same thing... AT&T Screen and it's hung. everything on this board is shielded.. so i doubt it got ESD zapped, and i did take static potective precautions.
I bet this thing would look good with a .45cal hole in it.

#1 That's what I'd assume...and it's 22 screws with fine threading... And if you're getting the AT&T boot logo after a fastboot flash, the bootloader is locked.
#2 Customer's loss
#3 Never actually tested that, but I've never once needed a sim for it to boot up....actually, my first boot ever might have been sim free...been a year now so I'm not really sure.
And I didn't take static precautions.
You didn't accidentally warp or mess up the motherboard on the blow dryer part of the digitizer swap? Or any unnecessary bending on the board with you were prying the screen from it? Those two are the only "dangerous" parts in any Atrix HD repair...unless someone isn't steady with a screwdriver, then there are 46 "dangerous" parts to the repair.
Next time you power up the phone, hold down both volumes and power to access the boot menu. Use volume down to scroll to recovery and volume up to select it. Once in recovery, do a factory reset as well as any cache or dalvik wipes available. If a fastboot flash and all the wipes in stock recovery don't fix it, I'm not really sure what will aside from a new motherboard -- in which case you're better off spending an extra 20-30 and just getting a used Atrix HD like I did....I mean, 50 for just a motherboard or 80 for the all the hardware plus accessories...not really a hard choice seeing as the customer will at least have some backup repair parts in case something bad happens in the future.

The only thing you can flash with a locked bootloader is your stock rom with fastboot. That's it. When locked, if manually flashing all the partitions, flashing with RSD, wiping everything that can be wiped, and you're still not booting, then the phone is either truly bricked or you're not doing something correctly.
The only exception to the above is if something went bad during the OTA and you have some sort of partition mix up, in which case the official fastboot for the OTA might fix it for you -- there isn't a stock fastboot for the OTA yet.

[Q] Stuck in Fastboot with no recovery

It seems that your partitions were wiped, since the bootloader cannot get the radio version. You might need to flash a stock rom.
Stock Rom
How can I flash a stock rom when I can't even access recovery to do so?

Unfortunately the problem here is that your radio partition has been wiped out. It would be better that you take it to a service centre. You won't be able to flash the radio by unlocking your bootloader

Bricked Nexus6 stucked in bootloader with locked and stock recovery

Really trouble because of locked boot loader and stuck in boot loader with stock recovery. Try and with no luck cannot fast boot flash anything because it always ask for unlock boot loader allowed in developer mode. Don't understand google on this features at all. All is stock if anyone have anyway to tick the box without boot or force flash with locked boot loader.
your only option is to rma it. theres no way to fix your error.

Sorry, but there's nothing you can do under the situation you describe. You will have to return it for repair/replacement.

well, its a security feature. to prevent people stealing your device, then factory reseting it to set up their own account. if there was a way around it, it would make terrible security.
So if you hit start it just goes straight back into the bootloader?

If your device is bricked, and your bootloader is locked and you do not have TWRP recovery installed, then the only thing one can do is return the device for repair or replacement.
On the other hand, if bootloader is unlocked and/or one has TWRP recovery installed, then it is relatively easy to fix.
still no findaway method so far? of it is possible for me to adb push from stock recovery? Do we have that kind of firmware.zip other than factory image flashing?

everything i've read points to having to flash a new recovery and then a rom. He needs pictures on it. it's of his newborn after she was born. Super sentimental.
Is there anyway to get it to boot or do an adb pull from recovery without flashing a rom and loosing everything?
any help is greaty apprecited.
also, can someone post the link for the mini adb?
edit: He swears he has not tampered with the phone as far as bootloader,unlock or flashing. he said he replaced the screen and thats it.

Using adb from recovery is only possible with a custom recovery, not the stock recovery. Flashing a custom recovery requires to unlock the bootloader, unlocking the bootloader will wipe all data.
Are you sure there is no button stuck? Maybe the volume down button is stock and thats why it always boot in bootloader mode? Test all buttons when in bootloader and make sure they all work fine. Otherwise you'll no other choice than flashing a ruu (will wipe the phone) or unlock bootloader, flashing a custom recovery + a rom (will wipe the phone).
Sorry about your brother's issue mate... But anyways, what gallery app did he use? You might be able to find those photos online if he used GPhotos, maybe even stock Gallery. I think HTC has their own cloud service on there too.

How To Unlock the Bootloader?

Hi, I just got a T813 and I've searched the forums (maybe not hard enough?) but I couldn't find anything about how to unlock the bootloader. Can someone please explain how to do it?
Or is it already unlocked?
OEM unlock is a switch in developer settings, activate and you are set. AND NEVER AGAIN disable it unless you are fully back to stock!

Simple. Unbootable device aka Semi Brick.
Does unlocking the bootloader wipe data (factory reset) on the T813?
edit: So I enabled EOM Unlock in Dev Options. Didn't wipe my data. Now, I just need to figure out the correct recovery image to use for my T813 with stock Nougat.

T813 doesn't have a locked bootloader.
Lots of misinformation about OEM UNLOCK.
It's a security measure implemented by Google. Samsung use it to enable/disable FRP on their devices.
Nothing to do with unlocking the bootloader.

But it has a bug:
"Reboot to recovery loop when using reboot utilities. Use hardkeys combo only to boot to recovery POWER + HOME + VOL DOWN.
If you get stuck in a recovery loop reflash TWRP with auto-reboot enabled."

"Reboot to recovery loop when using reboot utilities. Use hardkeys combo only to boot to recovery POWER + HOME + VOL DOWN.
If you get stuck in a recovery loop reflash TWRP with auto-reboot enabled."
So I switched to the one from the TWRP website: https://twrp.me/samsung/samsunggalaxytabs297wifi2016.html

I appreciate the reply and info. I did find that same TWRP and have it installed.
"T813 doesn't have a locked bootloader.
Lots of misinformation about OEM UNLOCK. "
so does the OEM unlock toggle require switching on to install TWRP ?

It needs to be enabled to flash anything custom and should never be disabled.
