I've been having issues with my phone for a while. If I let my phone battery die to the point that the phone shuts off, it is nearly impossible to get back on. I can boot into bootloader but that's it. The status will say "Battery OK (charging)" which is a lie. The battery is not OK and it is not charging, which is why I can't leave the bootloader and boot android. It also says "Connect USB Data Cable" even though it is connected but I'm not sure if that's typical. I usually have to play around with various combinations of restarting my phone/unplugging the USB cable until it finally starts accepting a charge.
Anyway, I'm trying to flash M but when I get to the point of using the bootloader, fastboot does not work. fastboot devices returns no devices and it fails. ADB works perfectly fine and can detect my device. I know my drivers are good because a) they were untouched and worked previously and b) I fully uninstalled everything and installed Android SDK and can access my filesystem.
I believe these two issues are related. I'm running 5.0.1 LMY47I and my phone is decrypted using whatever method Wug uses in his toolkit.
Addressing your points.
1) just because adb works doesn't mean fastboot will / should
2) SDK doesn't install drivers.
Do check device manager and uninstall the driver and reinstall the naked driver following instructions in my thread. Nexus general > sticky roll up > adb and fastboot.
You're probably right, they may well be related but I just wanted to point out that 1 and 2 don't necessarily point to that being the case.
well I did get further but it is not fixed. It is a driver issue possibly. I think I may have messed my phone up, its stuck on the "google" splash screen now
Each time I loaded something to my device, ie radio, it went back to "Connect Data cable" but if I disconnected it and reconnected it, it would then transfer.

This sounds dodgy and could be multiple issues.. Really.it's a case of ruling out the hardware.. Cable, USB port,.computer. .it's tricky because it could be driver related too.
So I tried again right after getting stuck on the Google screen and got Marshmellow working, but I still had to unplug the cable after every fastboot command completed. Windows would popup with an "Unrecognized device detected" window, and the device would show as Unknown Device in device manager under USB ports. After the fastboot command completed the message would go back to "Connect USB Data Cable" and would not work unless I re-plugged it..
I tried reinstalling the naked drivers but Windows says they're all the same and that there is nothing to update. I also have gone through the full uninstall using USBDeview . I have tried other cables, even with the charging fiasco. The one thing I have not tried is another PC but that doesn't explain charging issues.
Sounds like my Nexus 7's dodgy USB port. It's gotten a bump somewhere along the road and doesn't connect properly with the USB cable anymore. Only way I can flash anything is by firmly pressing the cable into the port the whole time.
What I'm trying to say is that it sounds like your USB port is broken. Possibly...
Well I'm just going to stick to stock Marshmallow so I don't have to worry about fastboot and I'm never going to let my phone battery die. I'll see how long I can go

Earlier today I was at my brother in laws house, was gonna copy some music from my phone to his computer (always have a usb cable in my car ). For some reason windows (vista) kept giving me unknown device and the option of mounting the sdcard never appeared.
I thought that was odd, never had the problem before, was short on time and didnt mess with it besides tryin to unplug and plug it back in. Well I get home and I see there is a new cyanogen build (a couple actually, mine is about 2 weeks old).
I plug in my phone with the normal usb cable I use and nothing. The phone charges (as it did on my brother in laws computer) but I the option to mount it doesnt come up on my phone. I dont see it in device manager and adb also cant find the device. USB debugging is turned on as well.
My only worry is that it is not a software problem because I got pretty drunk the other night and fell on my phone. The touchscreen is cracked a little but its just cosmetic damage, the phone has functioned 100% after that until now. Is there anything I can try here short of wiping and flashing my ROM again?
Tried searching but "sdcard mount issue" and other similar searches come up with pages and pages of unrelated stuff
Vista never sat well with my phone, ADB was a pain to get working and then, of course, I lose my data cable
But as far as that goes, I'm not even sure Vista works with the Android SDK, because I never got it to work. I was able to succesfully mount and unmount like it was a stock phone.
Your best bet is to, indeed, wipe and reflash. Use Cyan's recovery to make a backup and you can restore that after you sort things out with the sync'ing problems.
Well I have had the SDK working just fine, well adb and fastboot is all I have used on both my desktop and laptop.
Guess I will have to dig around for my adapter and give try giving it a wipe.
Well I just wiped and flashed the lastest cyanogen, before doing that I booted into recovery, hit the back button and it went into fastboot mode. I tried giving it the command to reboot, fastboot reboot, cmd prompt showed as it should be successful but it would never reboot.
I didnt think that was a good sign but I went ahead and wiped and flashed, same problem still persists. The sdcard worked fine in the adapter and both my ext3 and fat32 partition are working fine through the phone.
Anyone have any ideas? Would be nice if I didnt crack my screen, although its just cosmetic damage (phone functioned 100% for weeks now), I am pretty sure that will void my warranty if the phone were still under warranty.
This problem isn't huge, would like to be able to use adb again and not have to turn my phone off and use the adapter if I want to flash a new ROM.
Have you tried uninstalling/reinstalling the drivers in Windows?
It isn't showing up in device manager (only way I know to uninstall the drivers).
I think it has to be a hardware issue though, tried multiple computers, couple of different usb cables, wiped and flashed a different rom. Guess it's time to call up asurion

try that. if that doesn't work, its a hardware problem.
Yeah that didnt work either. Thanks for the help though guys, just sucks this is gonna have to cost me money through insurance for a stupid crack in the screen.
I'm trying to fix a friend's G1, which he bought on ebay from US.
I've no experience whatsoever dealing with Android, so this is new. But I'm fairly capable of understanding every technical process you could use, so I think I'll understand your explanations.
Whenever I connect the device to a PC via USB, the computer detects an unknown device, but the phone just restarts at the splash screen. Notice that it has two different behaviors: When there's no cable connected, it just shuts down after 2 or 3 seconds at the Android screen; when I connect a USB cable, instead of shutting down it restarts continuously.
The first thing I did was to unroot the phone and put the official RC29 rom. Unfortunately, the problem persisted.
I have access to the recovery menu and the bootloader (I don't know if this is the correct term, it's the Camera+Power menu).
The major problem (I think) is that I don't have access to the console, as the recovery menu I have is the original one.
So, can anyone help me with this? Thank you.
Options:
Root the phone and use a custom recovery.
ADB also enables use of the terminal through the shell command. -- You could also use ADB to get a logcat and see what happens before the reboots.
But I don't see how the terminal would help, it sounds like hardware failure if it does it with a stock and custom rom.
Don't I need access to the OS in order to root the phone?
Which SPL do you have?
A boot loop or crash at startup can be caused by many, many things.
Get hold of the android sdk.. inside the /tools folder are 2 programs called ddms and adb, you can start the phone while connected by usb and use either of these programs to grab a startup log. Post the log here and we can hopefully see what's causing the crash.
You probably shouldn't have unrooted the phone.. that's going to make things more difficult.
adb and ddms can't find the device. There's an "Android Phone" in the Device Manager, but as the phone keeps restarting, I guess it isn't on enough time to be able to be detected by adb and ddms.

Did you install the usb driver that's packaged with the sdk? the one windows installs by default doesn't work for adb or ddms.
If you've got this driver installed and ddms doesn't see the phone, that's pretty ominous.. it should show up there as "offline" as soon as you power it on.

Thanks, I fixed that and I got the ADB drivers, but the same thing happens. I can't get the attached devices, nothing appears on the list.
One note: this last time I tried to connect the phone via USB it booted, but I couldn't sign in, because as soon as I slid the keyboard, the phone shut down.
So, now I have a "Android ADB Interface", but still no devices listed with adb device.
Right now sometimes (like in 40 tries) the phone turns on and I can use the touchscreen, but when I need to sign-in, it tells me to slide the keyboard and it shuts down.
I still can't get the attached devices using adb, even after trying in other computers.

what happens if you start with the keyboard open?
you know, it could be a hardware fault, a dry joint or loose wire
the sliding of the keyboard just jolts it.
Hey guys,
For some reason, I can't mount USB unless I'm in debugging mode.
I plug the cable into my phone. The phone will bleep. I'll see the little USB logo and in the pulldown, under ONGOING, I can see it there, but usually there is two lines of text, but I only see one. When I click on it to be presented with the mount option, I hear the bleep when I click it, but nothing comes up.
Or maybe my PC isn't recognizing it unless in debugging mode? I have all the drivers installed. I'm positive I do, because it was the only way to get the super one click root. I've never had problems mounting.
On a side note, maybe it is relevant, my wifi connectivity has gotten really bad the last few days. My connection has stayed the same, and I've check all the usual PC settings, power cycle, etc. I can't check my Twitter, I can't send emails with attachments. Uninstalling and reinstalling the Samsung drivers didn't work. When in debugging mode, and I plug in, I did notice in the device manager, there would be something "ADB" popup. That's what's not showing itself in non debugging mode.
I'm not sure what I could have done. Any ideas? Thanks!
Go in to settings, usb settings and choose mass storage, if it's set to ask on connection it sometimes doesn't bring up the mount option in the notification bar, you'd think it would mount auto magically but it doesn't.
Edit; sorry didn't read the whole post, sounds like a driver issue..

I figured that much. The combination of things I've attempted so far regarding the drivers has not been successful.
Mounting USB on Rogers
Hey there I've noticed the same problem until I actually pulled down the top menu bar at the top where the USB symbol is. You pull that down and look for the USB settings icon tap that and choose MOUNT and or UNMOUNT.
Hope this helps....I only noticed this on Eclair 2.1 and not on Froyo where it actually brings up a dialogue box.
Just a word of advise, when you unlcok it with the unlock software from here beware you might end up with a generic or false IMEI number as I did.
I get the drop down, and I see the USB option, but clicking on it does nothing. The PC won't recognize it.
For those who are having this issue, the only way I've manage to fix this is:
1. Uninstall Samsung drivers and delete extras manually.
2. Restart PC.
3. Reinstall driver.
4. Restart PC.
5. Plug in device and give it a few minutes.
I'm on Windows 7 64bit. I've had to do this twice so far, and it worked both times. Hope it helps.
I had this problem also and after looking around I found several people that suggest switching to a USB port right off the mobo. After doing this it connects every time.
Hello,
I unlocked my device by using ASUS unlock tool. Everything went well. I also can see the message "Device is unlocked".
Then I tried to connect my tablet with my computer to install TWRP and further a cutom rom, but this is not possible. If I connect my tablet with my PC nothing is happening at all, means tablet is not recognized at all. I'm using Windows 10. Anyway, my mobile phone is recognized. I already tried to set it back to factory settings, flashed the latest Asus ROM, but nothing helped.
The other curios issue is that the tablet is not able to recognize that the battery is charged. LED is lightning and battery is charged, but tablet says power adapter is not connected.
Any idea? Could it be the cable? I already tried to connect the table over the dock, but same behavior. Dock LED is lightning as well.
I'm really frustrated. Hope anybody can help. I really need to establish the connection to my PC to go ahead.
5.11.15 - Update:
I realized that it seems to be an issue with USB. As mentioned above USB to tablet is not working (no PC can recognize it). If I connect the keyboard no USB device will be found. Charging the tablet is also not working, except I connect the power adapter and cable directly. Any idea?
Thank you.

Duchman or Dutchman? I'm having again exactly the same symptoms. Tried 3 different USB cables too. Dit yóú manage to get this sorted? I know it was 4 years ago but my TF701T is still working properly, for the most part.

That is exactly the same behavior. Best for now is to charge with the device powered down. I'm about to open up mine to doublecheck if the USB connector is seated properly.
Weird thing is that the keyboard also fully works which should not be possible if the USB port on the tablet was malfunctioning right?
I'm having a lot of apps not displaying anything anymore so was going for the KisKatt rom to see if that fixes the lot. Also I see after some time some apps keeping the device awake all the time so battery is always drained when tablet is closed.

My TF701T is sitting disassembled in one of my drawers after an unfinished screen replacement attempt. I did manage to install TWRP on it, however, I don't remember what I did exactly to accomplish that.
I might have used one of those shady rooting apps that I'm not sure if I'm allowed to mention here. Then I probably flashed the TWRP with Flashify. Basically, circumvented having to connect the device to a computer up to the point where I had a working recovery on it.
Don't ask me for the exact steps because I wouldn't be able to remember anyway. I'll lay out a basic plan of action:
1) Find an app that lets you root your device without connecting it to a computer. Be warned, those more often than not come bundled with malware, so exercise caution. I'd back up all the important files and information and do a factory reset before attempting this if I were you.
2) Install Flashify, grant root access, download TWRP zip on your tablet, flash. Do some research on how Flashify works and how to use it before you attempt this.
Good luck, and if anything comes out of this, be sure to come back here and report on what you did in case some other poor soul wants to install a custom recovery on their 7 year old tablet without using a USB cable.
I just had mine crap out for some reason and needed to reformat everything and re-install. Connecting the USB to my PC, the PC makes the connected sound but no drive or anything showed up. I couldn't be bothered to figure out why so I just used adb to put the files on the tablet.
adb push yourfile /sdcard

MTP mode vs camera mode?
Does kies recognize it?
Also as strange as it sounds, you may toggle developer options and usb debugging on and off. I did this on a family members ASUS tablet that displayed the same issue and then the PC recognized it. I was just trying everything I could think of.
Edit: I just realized you said Odin and not just connecting as a normally powered on device. Do you have it in download mode when connecting to the PC with Odin running?

unfortunately i cannot get the phone to bootup as to get into the hidden menu and turn on the MTP that way and yes if i am trying to connect to the phone to use odin i am in download mode when i try to connect.. the phone does not want to connect to the computer no matter what i do ive finally managed to get it to download mode and now am going to try and flash a different custom rom in the hopes it will boot up.. if it will do that i ill try and get mobile odin.. but even that hasnt been working. when i install a new rom and click on reboot the phone just shuts off. the phone wont turn back on after that unless i leave the battery out for several minutes then put the battery back in and press the power button. upon doing that the phone instantly boots to recovery.
This happened to me.
I even replaced the USB Port (Then dropped the phone while it didn't have the frame on and cracked the LCD)
The phone's USB port still didn't work and I had to replace the phone.
it is a very, very odd bug with this phone that multiple people have been experiencing but no one knows the cause of it.
It may just be faulty phone. Several people recently have had this bug.
my phone was made in Korea, Region: USA-Revision Q8R2.
N910T (UD)
So. Sadly, the only way as of right now to fix this is to get a new phone.
I tried a lot of things with my phone before I broke it to attempt to fix the USB port.
And the issue also lead to slow charging (220mA) and when I plugged it into the wall it would say USB Charger not AC Connected
Are you using the oem cord that came with the phone. I've experienced issues using non oem cords.
Yes sir I've tried multiple OEM and non OEM cords still won't recognize the phone

Did you try ask the different USB outlets? Did you try a different computer? For me USB 2 works, but not 3. Also I've had trouble with those on the front of the case. I always use the ones on the back. Just throwing a few things out there. It's possible you have a bad USB port on the device.
