Strange Behavior after Low Battery - One (M9) Q&A, Help & Troubleshooting

Hi! I'll try to make this short.
My M9 recently died and refused to turn back on for at least a couple of days. Suddenly, it decided to start booting automatically and directly into download mode (no idea how or why this started when it did). While it's in download mode, neither of the volume buttons has any function; only the power button will select the top option. I was trying to figure this out when I came across a thread on another forum somewhere online which made me think that my problem might somehow be related to the charging logic. However, I can't reset the charging logic (which I believe would be by holding all three buttons for 2 minutes) because the phone will not stay off whenever its battery is holding a charge. The only other thing I can do is to boot into the bootloader. However, the unusual button functionality is different in the bootloader; volume up moves the selection up, volume down does nothing, and the power button moves the selection down. I am able to boot the phone into safe mode from the bootloader if I use fastboot (>fastboot continue), but I can only boot into safe mode and so obviously the phone's functionality is still very limited.
I'm not really sure what could be causing this behavior. It's been some time since I've modified the system software (several months since I've modified the actual system software, even still only a couple of months since I last installed an ordinary app). I've tried connecting a new battery with no luck. I would like to just do a NAND dump and then possibly move on from the M9, but I can't boot into recovery mode, I can't use any third party apps, and I can't use adb because, for some reason, I can't enable USB debugging (must be a part of safe mode).
I appreciate any advice you can offer in advance. Even if all you can say is "it's probably just broken, no luck," that's cool with me. I would really just like to know what's going on and if possible, ideally fix it or at least somehow do a NAND backup, but I've exhausted all of the options that I'm aware of for now.
Thanks,

Did you replace the battery after this behaviour started occurring? Or did you do it earlier?

[Q] Tried to install Beatmod ICS, stuck on "screensaver" usb and recovery won't work

[Q] Tried to install Beatmod ICS, stuck on "screensaver" usb and recovery won't work
Hi guys,
I've watched the n00b video and been googling for the last few hours as well as reading through various pages on the XDA forum. I've found a lot of problems that are kinda similar and tried various solutions but don't seem to be quite getting there.
Basically I had Virtuous Affinity as the OS and clockworkmod installed (should be the most up to date versions of both, they were put on no more than a week ago) as well. I also had a backup of current OS and so on on the SD card, as well as the original zip of the rom.
I decide I want to give ICS a go and so I downloaded the betamod ICS and then loaded it. It asked me if I wanted to do a dalvik cache wipe, a dalvik cache + data wipe and a third option I don't recall. I went with the dalvik cache wipe (at the time I was under the impression that was the correct course of action) then put it back in my pocket while ICS installed.
I get my phone out of my pocket later and it's kinda stuck on what looks like (but logically isn't, I'm guessing it was meant to be a splash screen type thing while ICS installed or some such) a screensaver which just loops endlessly. The only thing you can really do is take the battery out and turn her on again, in which case you once again end up in the endless screensaver loop.
I've tried booting to recovery using volume - and the power button and unfortunately it just boots straight into the looping screensaver again.
Getting a bit worried and feeling adventurous I tried seeing what I could do with ADB, however the computer seemed unable to recognise that any device was connected with ADB devices not listing anything.
I've read up a lot and I'm at a loss as to what to do - there's a rom on the SD card and there also should have been a backup but I just can't get it into recovery.
I do have the ability to view the SD card on another device and interact with it, so if there's a potential SD fix, that's certainly not out the window.
But yeah, I'm clueless how to proceed here and very green at the whole rom business. Can anyone advise what I might try to do from here? I don't care what state I end up going back to, or if I lose my data, I can get all that back, I just want the phone in some semblance of basic operation.
I'll be keeping an eye on the thread, if I've left out any pertinent data ask away and thanks in advance for anyone with a clue how I can fix this mess .
EDIT: Post may be better off in ICS thread above and I do apologise if so, I would move it but I seem unable to delete it.
Remove battery for 5 seconds and then try again to boot into recovery using volume -and power button.

I have, it doesn't work. I've left the battery out for a fairly long period. Volume - + power still just brings it back to the "screensaver" loop.
Thanks for the suggestion though.
Turn the phone off completely; pull the battery out for a bit then replace it and don't touch anything. Don't try to turn it on. Plug the phone by usb to your pc (still turned off). At the command prompt in the folder containing adb.exe type "adb reboot recovery" - the phone should power on and go to recovery where you can wipe properly and reflash whatever you want.
You should be able to boot to recovery using the volume down + power button combo (hold the volume-down key, then press and hold the power button and keep both held until you get to the bootloader menu); the only thing that's wrong with your phone is that you've flashed one ROM over another without wiping it first, so the ROM can't load but this shouldn't affect your bootloader or recovery.
Worst case you can flash a RUU which will restore it to the official firmware; you'll then need to re-root and re-install a recovery image to be able to flash custom ROMs again.
Very helpful post, thanks! I'll try all that and see how I go, I'll post if I still have trouble.
Yeah I dunno why I can't boot to recovery it's weird. The volume button wasn't working, so I removed it and am pressing in the volume down portion of the volume button with a pen while holding down the power button. It's possible perhaps I'm not successfully depressing volume down, but I'm 99% sure I am and that that's not it. I am however doing it as you and other guides advise, depress volume down, hold it and then depress power and hold both for about three seconds, no joy!
Anyway, as said, I'll try what you're recommending and see how I go. Thanks!

Curious what you mean by this? Cause there's no command prompt in the folder ADB is in. Do you mean in command prompt, be in the folder, i.e. c:\abd kinda thing? I tried just loading command prompt and typing abd reboot recovery, no device detected - no joy.

Yeah that was what I meant; I've got a feeling that that only works when the phone is powered off if you had USB debugging activated on the phone beforehand, so if that's not working that might be why.
c:\adb
results in error: device not found.
ADB app itself is in C:\adb\platform-tools but when I try that it goes The System cannot find the path specified. I've tried cd/adb and I can get that far but I can't get to adb/platform-tools.
EDIT:
Okay, I managed to get to c:\adb\platform-tools but adb reboot recovery is still advising error: device not found. Guessing perhaps I didn't have usb debugging enabled. Are you able to suggest another work around at all? I'm happy to flash it to whatever, I don't mind losing data, just want to get it in working order again. I don't see how I can though when I seemingly don't have access to recovery or USB...hrmm, must be some way around.
Accidental double post, sorry.
You need to try get into recovery mode, where you can do a full wipe and see if that fixes anything.
Firstly, remove your battery then re-install it, your phone should still be turned off at this stage. Press and hold the volume down button, then additionally press and hold the power butter, until something appears on the screen. If the bootloader appears, you can then boot into recovery from there.
If the above fails to work, report back with your results and hopefully something else will be suggested.

Your only other option to get into recovery is the volume-down/power-on combination. Like I said, I can't think why that's not working unless it's related to your missing volume button (maybe it's not maintaining a constant pressure on the button when you're using whatever to press through the hole).
If you still can't get that to work, I would suggest finding a stock RUU and flashing that. It's an .exe file that runs from your PC and will return your ROM, bootloader and radio back to stock. Obviously that means you'll lose root and your custom recovery so you'll need to do all that again from scratch. There's a sticky in the dev section with a link to a thread with various RUUs (it's named something along the lines of "shipped & test ROMs" - I'll check that and link to it once I've dragged myself out of bed to the computer). You'll lose all your data, but if you took a backup beforehand you can restore that once you're back up and running.
//sent from my Desire HD using Tapatalk; all errors entirely intentional.
Yeah I'm starting to think perhaps the down button is just broken.
What state should the phone be for the RUU, turned off with usb plugged in or turned on? Bearing in mind, that when on, all it will do is the "screensaver". Will it work in either of those states?
Thanks, will deffo research more when I get home. Appreciate the help immensely.

Guessing you mean that as far as the ruu thread. Am downloading a stock rom atm, with shaped internet till tomorrow, meh! Will see how I go. Have a feeling phone was probably Vodafone branded at stock though, so that could make for extra fiddling but yeah, fingers crossed.
If you are able too install a stock-rom you can work from their than install 4EXT recovery
touch than you doen't need the volume buttons.
I downloaded the most recent stock rom on the link above. When I try to install it though, phone off or on, it advises a USB connection error. Is this likely to be because I originally had vodafone stock and need to make a gold card, or should it still at least be recognising it? It does advise not to run any programs on the phone or anything when while installing the update, but of course, as long as my phones turned on it's stuck on the damned screensaver loop.
http://forum.xda-developers.com/archive/index.php/t-841890.html
Gonna give that a go, fingers crossed!
D'oh, just found out my mobile was Three at stock and not Vodafone, the search continues .
Gah, I'm about tearing my hair out here, I want my damned phone back . Stuck using a $79 Huwawei Vodafone thing at the moment and it's so so so awful.
Anyway. I was under the impression that making a goldcard would mean I could RUU a non-Three stock rom on the phone. I made a goldcard following these instructions; http://www.addictivetips.com/mobile/how-to-make-gold-card-for-htc-desire-hd/
Then I turned the phone on as the RUU advises, (meaning it's scrolling through the feckin' "screensaver") and start the process and once again get a USB connection error.
What's the better process at this stage, try and take it back to Three stock? I don't see how I can at the moment, the only Three stock I can find seems to be rom, not RUU, meaning I'd need to load from the phone, which I can't due to no recovery. Or should I keep trying to get the goldcard thing to work, maybe try some different RUU's or something?
I'm open to any other suggestions as well. Had a bit more of a fiddle around with my volume down button, no matter what I do though, I can't get recovery mode. Always boots first to the white HTC screen and then starts the infernal "screensaver" loop.

How come the volume down button be broken. When you were using Affinity Rom weren't you able to use your volume button for music. Remove SD card from phone then press "First - Volume down gently for 2 sec" & press-hold power button when it goes into bootload place your sd card back select option "REBOOT RECOVERY". I think your panicking too much just be patient nothing is wrong, i think your just hurrying it up...
The volume button didn't work before either. I had to manually adjust volume from settings. I thought it was just because of the dodgy plastic button on top, but using a pen to depress the button underneath doesn't work either.
Believe me, I've been trying to fix this for days now, every different way of depressing volume down in order to get to recovery has not worked. Short of taking the phone apart and seeing if I can see what's wrong with the button (doubtful with my level of expertise) then it ain't happening via that method.
Got a little bit hopeful with this;
http://www.htcdev.com/bootloader/ruu-downloads
But that too requires my phone to be in usb debugging mode, which of course, it isn't.
Is there anyway to force the phone into usb debugging mode using some form of hack or some such? The thing is, it is powered and everything, I can turn it on, the screen works and all that jazz and indeed the phone will charge from USB and the computer makes a noise when I plug or unplug it, the phone itself however won't do anything other than the "screensaver" ICS installation loop. I guess I'm thinking where there's life there's hope and perhaps there's some way in that state I can get it to switch debugging on, though I think I'm reaching at this point .

The only option i can think of is "Fix your volume button from your nearest Service centre". Without that you cant do anything. I am Sorry....

Options for Recovering Files & Phone Repair???

Today hasn't been one of the better ones this week. Putting aside my pride for a moment, here's what happened. In my frustration, I threw my phone into a cardboard box. Aiming for the side of the box...it ricocheted of the floor then the side. Yeah, not the best available option to vent!
So...screen spiderwebed and the screen will no longer turn on. Phone vibrates when the power button is used, yet screen is blank.
I'd like to ask for help for the following:
Retrieve several important files that weren't back yesterday: Pictures & program files not synced for privacy reasons, plus TWRP backup from a couple of days ago to internal memory b/c SD full.
Screen damage or more involved? To determine if I spend time fixing or buying a replacement phone.
Phone is the Canadian Koodo T989D running CM11 8/04 with TWRP 2.7.1
Phone Symptoms:
After removing and replacing battery
Pushing power button - Normal 'turning on' short vibrate, screen doesn't turn on (no light/pixels light up)
Recovery Mode - Normal Vibrate, release pwr button and again screen blank with exception of top Left corner showing multiple pixels, unrecognizable
Download Mode - Plugging in the USB cord causes the phone to vibrate every 2 or three seconds and the cycle repeats. vibrate...vibrate...vibrate...continuous
Any thoughts on troubleshooting to determine if retrieving files on the phone is still an option?
Would appreciate ya'll sharing your common knowledge that uncommon while I'm this frustrated. After switching to an AWS service provider (WIND) 2 weeks ago my backup phone isn't compatible - Galaxy Ace GT-S5830D. Thought it was until I tried, then realized it isn't. I'm kind of flustered that I acted so impulsively and doubly because I thought I had a backup phone, ughh!
I believe you deserve to feel bad for having acted upon anger for trivial matters! I'm glad you feel bad too because after all, that is the way we discover ourselves and learn from our mistakes! :good:
As for the phone, I had a gut feeling based on your post that there may be a power/voltage problem (maybe a short?) because the behavior in Download mode seems like the behavior when you try to boot the phone without a battery (using only usb power) and there's not enough juice to do anything useful.
My guess is either your battery is damaged, or a short somewhere in the phone (perhaps the screen?) might be draining too much power.
If you get it to boot and have usb debugging on, you can access your data using ADB. I believe CWM and TWRP both have ADB built-in also so you might have some luck there.
Can your computer recognize the device?

Thanks for the educated guess and ADB suggestion to recover files.
Yes the computer shows 3 drives when attached in Recovery Mode. And darn it I can't remember if debugging on or off. The computer doesn't recognize the phone by default while in recovery mode. If this is the case, would ADB likely allow access to the phone? Not a tool familar with yet.
Unlikely that the battery is damaged if the phone turns on. Still stays cool while on or charging. Which is good news.
Do you suggest installing ADB and checking? If so, which version of ADB? Seems there are more than a few, plus multiple drivers and would rather not get hung up on troubleshooting installation.

I don't understand why you see 3 drives... I'm sure Windows will ask you to insert removable storage if you try to access the drives, right? If that is the case, and you have no screen/touchscreen, only ADB will allow you full access to everything in the phone.

Yes. Here's the tricky part though, in order to make adb work, your computer needs the right drivers for your phone.
I think you should try to follow the HOWTOS (How to Install Android ADB Interface Drivers) on installing the drivers for ADB.
If all goes well, you can check if it worked by typing 'adb devices' from the windows commandline. Then it would be possible to use adb to get your files back.
If the phone boots into the system...if, since you can't see it....you should be able to open the sd folder on your pc and simply copy/move what you want to the pc.
Just checking if you've tried this.

OPPO Keyboard has stopped working, leading me to stuck on a fastboot loop.

Please help. This is a serious matter for me.
Started having this problem at February 14th, 02.10 AM.
Have been looking for the answers in the Oppo Forums too but still got no answers.
Okay, I have a habit, which is moving all of my applications from my internal storage to my external SD card, after I let those applications doing their functions and programs and features and so on for a while. It's not a big deal for me to set up my phone again after I restarted it, and usually it works perfectly. Just restart and I would get to operate my phone again. However, this time, I got a bad luck. The worst one, considering the fact that I'm all-around-gadget.
Here's the results I got from reading a lot of threads (not only from this forum and OPPO forums):
OPPO Swype Keyboard has stopped working? Really?
After restarting my un-rooted Find 7 (9076), I cannot type the password on my lock screen. Like any other Android devices, it would always come back to it's system or default applications, I knew that fact. But this time, when I touched the blank space to type my password, nothing came out. No OPPO Keyboard, which happened to be OPPO's default keyboard. No other keyboards. None at all.
So, I cannot do one single thing to my phone except just turn it on and stared at it like a complete idiot.
Then I decided to turn my phone off and turn it on again after a while.
But still, the same thing happened. No keyboards.
That time, I decided to turn off my phone again and pulled out the battery and my external SD card.
After putting the battery back (External SD Card was still outside), and turned it on again, the same thing still happened.
Sliding my fingers up and down, nothing happened. The touchscreen was still there, showing me my date and time even though I was sliding my fingertips up and down.
Not too long after, I felt my phone got warmer and warmer. I tried double-clicking the home button, which I already set to unlock the lock screen, was also useless. The screen was still black and locked. When it got over-heating, automatically I pulled out the battery without even turning off the phone.
That one was my fault. I knew, and well, honestly speaking, this is the first time I'm in this kind of situation. In the past, my Find 7 would just suddenly restarted itself then everything went back to normal, but not this time.
And here's the beginning of my Fastboot Loop.
Fastboot Loop on un-rooted device
After pressing the Power button and the Volume Up button at the same time, it would bring you to the Recovery Mode. When I did that to my Find 7, it brought me to a black backgrounded screen with cute OPPO mascot and some Hanzi (Chinese handwritings). Picture attached.
I tried to wait for 2-3 hours and found nothing happened.
Pulling the batter out and putting the batter back would do the same.
In other words, I am not able to gain access to my Recovery Mode.
Why didn't bring the phone to the service centre?
I thought about this already.
When I tried to connect my phone to my pc, it can detect the phone but cannot access the files because the phone was still locked with the password.
Usually, the service centre requires us to unlock the phone if there's a problem with it, right? In my cases, yes.
I was searching all night to find out the answers.
I found some threads about the Fastboot Loop thing and etc, but they are only for rooted devices.
I'm using:
OPPO Find 7 (9076)
Color OS 2.0.5i Beta
Android KitKat 4.4.2
Device is not rooted, still original.
Still dealing with the same problem until now (the time I post this thread).
Anyone has solved this problem and guide me step by step to finish this?

boot into recovery and format the phone, this should fix it. If you want to backup your data, just boot into fastboot, connect phone to pc, run fastboot command from sdk tool, push custom recovery, flash twrp, make nandroid backup, fomat phone along with all the storage and then flash oppo stock rom (you need to download) or any other custom rom with gapps. To restore use nandroid manager, do not restore system files if you are flashing custom rom.

Thank you for your help Sir.
But, my Find 7 already operated normally again since I left it for a few days uncharged and off.
Then I got into Recovery Mode by pressing Power button and Volume Down button (not Volume Up button) while in the middle of my fast-boot loop.
It worked. I could gain access to ColorOS Recovery Mode.
So, I reset my Find 7, then re-installed my applications and everything again.
Thank you for answering!

SM-T705 Bootloop

Alright. I've not used this device for a while but now I'm trying to fix it. So far :
1. Device goes on a constant bootloop.
2. I can boot the device if I hold onto the power key. If I let go, it just turns off immediately
3. Can't select anything in bootloader since if I let go of power key (which is to select) it just turns off
4. Tried factory resetting, it's now reset but problem persists
5. When in Download mode, it seems to be able to keep itself on however Odin doesn't seem to detect it. (Windows chimes that a new device is connected (sound only); no warning that device is "malfunctioning", doesn't show up in device manager)
6. Banging the side with the power button also didnt work lol
Extra:
If I put tape on the power button it is able to run perfectly fine. Any ideas?
I'm honestly guessing its a sticky power button. Battery problem is probably not the cause since it's able to hold up normally in Download mode.
Any help is appreciated, really damn confusing. I've never seen a post as such, so if I get this resolved hopefully others can repair theirs aswell.

Same issue
Exactly the same issue here.
I've even replaced the battery, didn't help.
Did you repair it somehow?

Recover files from a Pixel 3 XL that cannot boot anymore

Hello everyone,
I come here because I have a big issue with my Pixel 3 XL.
It's up-to-date regarding the OTA updates i.e. I have the latest firmware installed.
I've never done anything special regarding "tweaking", such as enabling the developer mode i.e. the developer mode is unfortunately not enabled.
I was browsing the Internet and the phone suddenly rebooted unexpectedly. Then it was in a reboot loop. I pressed power and volume down buttons to enter the boot menu.
The boot loop stopped but I was unable to do anything to make my phone boot properly again. In the recovery menu, there is no option to wipe the cache partition.
There should be roughly 400 MB of free space on the phone. I was thinking that maybe this could have been the cause of the issue.
When the phone is off and not plugged to the charger, the percentage of battery decreases. When the charger is plugged, the percentage of battery does not decrease but does not increase either. It seems I cannot charge the phone anymore. Currently remains 13%.
When the phone is off and I press the power button, the Google logo shows up and the progress bar below has just time to appear before the phone vibrates and goes off.
I don't care much saving the phone, but it's extremely important to me to be able to recover the photos it contains (standard DCIM folder).
Most of what I found googleing so far is about wiping the cache partition, but there is no such option on my Pixel 3 XL.
Since the developer mode (USB debugging) was not enabled when the phone was working fine, I cannot use adb to pull files. I can sideload though. As far as I understood, in my situation it is not possible to enable the developer mode.
I've just heard about TeamWin Recovery Project, and still trying to figure out if this can help me.
Could someone please tell me how I can, at least, backup my photos?
Of course the best would be able to boot the phone normally, but really my first goal is to save my photos.
Is there a way to reflash the firmware with the same version, or another version, without losing data, just like what happens on a regular update e.g. when a new Android version is deployed?
Thank you.

I don't think there is anything you can do without developer mode, but aren't your photos backed up to Google servers at https://photos.google.com?

no, I don't synch with the Google cloud.
I've just read that in order to install TWRP, I needed a unlocked bootloader, which is not my case. Unlocking the bootloader would cause my data to be wiped (for security reason it seems). Is that true?

Unfortunately, that is correct. Unlocking the bootloader wipes the data. I know of nothing you can do.
was your problem resolved?
