The power button of my tablet has been broken. I would like to download and delete my data before i send it to repair. Is it possible to turn on the tablet or do a factory reset without this button?
If you're lucky the power button hasnt snapped off from the solder lugs, from there i suppose you could remove the plastic power button and put the tablet back together and hit the button with a pencil or something and get into recovery. Unfortunately i have had 3 of these buttons break on 3 separate tablets and every time for me the power switch has completely broken off from the PCB, so data recovery was not an option.
And Lenovo, for whatever reason has deemed it easier to replace the whole mainboard by default (the power board itself is not connected to the main board at all) and upgrading you to the unrootable OTA version. and giving no option to retain customer data. though they seem to be pretty good about preserving data on Laptops and dekstops. so even if you have a nandroid backup theres no way to restore it because you cant install CWM! and no way to run any good backup software on the tablet without root! Lenovo completely lost my respect. since i lost a hundred or so hours worth of work my tab (sketchbook adobe suite) has turned into a bookend, I really hope you are able to make a backup and if not hopefully you get to keep your data, and hopefully all my *****ing and complaining towards lenovo will help somebody out
My Galaxy S5's physical power button has stopped working. I've rooted the phone and reconfigured the keyboard configuration file so that my physical "home" button now serves as a power button. I've also disabled the two backlit buttons on either side of the physical home button and have enabled the stock Android softkeys for navigation. (The backlit buttons were malfunctioning as well, so I disabled them.)
The phone currently works great... the problem is when I try to change batteries. Since the normal power button doesn't work, I can't use it to turn on the phone. (The keyboard configuration tweak kicks in when the phone boots up, so the central button doesn't wake the phone after the battery swap... the phone has go through its boot procedure before that button would work.)
I figured out that if I can get to recovery mode, I can select the reboot option and the phone will turn on just fine.
The problem is that I can't usually get to the recovery mode, since the power button usually doesn't work. Sometimes it seems to work (and I can press power-home-up volume to reach the recovery mode).
Is there anyway that I can reach recovery mode without using the power button? Is there any tweak I can make to a BIOS or other pre-boot configuration so that the phone can reach recovery mode (or just turn on) without using the power button?
I can't take the phone back to Samsung for repair because I broke the screen and had it fixed by a third party. I've rooted the phone in order to reconfigure the navigational buttons, so I do have root capabilities. I'm using the stock Samsung firmware, which I'd prefer to keep using since it has the best camera driver for the phone.
Thanks!
There are apps that let you boot to recovery, check Play Store
Also ADB commands you can use, a quick google should find them, I can't remember them off hand

Thanks for the reply. I browsed the app store, but the apps seem to be widgets that let you enter recovery mode. My problem is that after the battery is swapped, the phone needs to be turned on before I can get to an app. I can't seem to reliably turn on the phone because the power button usually doesn't work.
Is there an app or configuration process that will let me configure the physical home button to have the power to turn on the phone? Currently, I have the home button configured to wake the phone, but to get the button to that state the phone must first boot up and go through the key mapping routine. So, the home button currently won't start up the phone if the phone is fully powered down (not just screen off).
I'm open to any other suggestions for how to restart the pone when it's truly fully powered off.
Maybe I just need to take the phone to a repair shop for them to repair the power button, but I was hoping to avoid the expense through reconfiguring the phone, if possible.
Ah I see, does connecting the charger not power it on ?

When plugged into the charger, the phone lights up to show the battery charge level (green battery with bubbles rising from the Home key). To get the phone to boot up, I still need to use the power button, which usually doesn't work. It's really frustrating, because the power button is temperamental. I basically have to keep trying to get it to boot or go to recovery mode, but it can take a long time and I fear that the power button will give out completely soon. Currently, it seems to work maybe 5% of the time.
Otherwise, my phone is fine, so long as I don't swap batteries or fully power it down.
The problem is that I often need to swap batteries in the wilderness, while on backpacking trips etc., so I don't have a laptop or charger handy to help out. I was hoping to reconfigure the phone somehow so I could start it from a full power off state without any external helping device, like a laptop or USB cable. I use the phone for topo map navigation. I'm pretty good with map/compass navigation, but I'd really like a reliable way to reboot the phone in the wilderness.
Thanks again

1
With your phone turned off, press and hold the Volume down and Home buttons.
2
While holding the Volume Down and Home, use a USB data cable to connect your phone to your computer.
3
Continue holding the Volume Down and Home button to until your phone will boot to Download mode.
4
Once your phone boots to Download mode, press on the Volume Down button to cancel the Download mode.
5
Once the Download mode has been cancelled, your Galaxy S5 will reboot.
Wait for your phone to completely start.
6
You have successfully turned on your Samsung Galaxy S5 without using the Power button.
Thanks. That sequence of steps will work great when I have my laptop handy. Do you know of a solution that would work in the wilderness without a laptop, USB cord, or power outlet? Generally, when I need to swap batteries and power down the phone, I'm in the wilderness.
I don't unfortunately, that was the only workaround I could find
Maybe you could fool the phone into thinking it is connected to a PC with some clever rewiring of a USB cable? Not sure how you would wire it, but Im thinking there may be a way to connect just a cable up so connecting it to the phone outside will make the phone think it's connected to a PC and allow download mode
It's possible that a USB 'jig' might help.......

I'm thinking now that I should visit the repair shop to see how much they would charge to fix it properly. I really depend on this phone in the backwoods and wouldn't want a work-around to fail me when I need it most.
I'll keep you posted on the repair/cost. Thanks for the help.

I've watched a couple of 'teardown' videos for the S5, and from what I've seen, the screen has to be removed in order to get to any of the power, home or volume buttons.......and it's very difficult to remove the screen without risking damage........I certainly wouldn't want to try, and that's speaking as someone who has repaired a number of Samsung phones......
In the short term, you could try the jig.....I know it works on the S2, just can't remember if it boots the phone *fully* into download mode or just to the screen where you have the 2 volume button options to either enter download mode or restart.......

I took the phone to the repair shop yesterday. It turns out that the S5's power button is just a thin tab with two metal contact squares inside the phone. There are prongs on the interior of the phone that make contact with these squares. If the prongs aren't properly aligned or properly bent to make contact with the tab's squares, the power button won't work. The technician was able to get the button to work by pressing his thumb on the screen by the power button while pressing the button. He's confident he can realign the prongs to make good contact. You do have to take off the screen to access the prongs, but since mine is a replacement screen already, he said it's pretty easy to remove.
My capacitive buttons were also dying and I had configured the keyboard boot files to disable the capacitive buttons. I had enabled the stock softkeys instead. The repair shop will be able to replace the "dock" component (which includes all the stuff at the bottom of the phone, like the capacitive keys, the charging port, etc.). That, too, requires removal of the screen, so while replacing the dock he'll fix the power button prongs. The entire repair is estimated at about $100.
I'll let you know if the repair succeeds. Yesterday I popped my SIM into an old Windows Phone (Lumia 521 running WP 8.1), and was reminded again at how much I dislike Windows Phone and how much I like Android. Absence makes the heart grow fonder... After a few hours of fiddling discontentedly with the Windows Phone, I put my SIM into my trusty Nokia 808 Symbian phone, which I'll use until the Sammy is ready.
Lol.....I moved from 'dumbphones' straight to Android.....so I've never had the experience of windows phones....though if it's anything like their PC OS, I'd have probably ended up embedding the phone in the wall........
Good luck with the repair, I hope they get it sorted for you.

Funny. Yesterday evening, I switched to my Symbian because I knew I was about to hurl the Windows Phone across the room if I kept using it.... The WP phone can do much more than the Symbian phone in theory, but in practice the old Symbian phone does everything it does really well and predictably, including multitasking. With WP, I'm never sure what the phone is up to as its multitasking is a joke. Some apps do in fact multitask, but others don't, and as a user, you can't tell which is operating in the background and which isn't, until you return to a background app and discover whether or not its been processing.
I've never used an iPhone, so I can't compare WP to iOS. But compared to Symbian or Android, WP will lead you to drink, and probably to drink heavily.
Lol.....having never experienced it's delights, I can't comment, but if it's anything like W8 on my wife's laptop I can see where you're coming from

Did you get anywhere with this? I have a Samsung Galaxy S5 G900F, the fingerprint scanner is for someone else's credentials and I don't have the login password etc. ADB is not an option as I cannot boot the phone to enable debugging mode. I have tried all methods of booting into recovery including Vol Up + Home + Power, this does not work.
Any suggestions would be appreciated
Have a good Easter bank holiday weekend!

If you are travelling this method also works with a battery booster (i have a bud one from a beer case...you charge it and take it with you..... ) it s stored energy backup battery that you plug in for a crappy charge)
so... when your on the road or in th woods, any power supply that you can connect (car charger, booster, etc will trigger the download mode and enable this solution. )
THANKS!!! MADE TWO USELSESS PHONES USEFUL AGAIN!!!
Hello guys,
I own LG G2 Intl version. A couple days ago the device has suddenly stopped charging with only rising 2% after 12 hours of charging then kept discharging until reaching 0%. Then it would never go above 0%. While connected with the charger, I can switch the device on. On the lock screen it says it is charging but in the Settings it says not charging. I read a lot of posts here in XDA and outside suggesting once a software issue and another a hardware issue.
Anyways, I have tried then a lot of chargers like original Samsung charger, Laptop current, original ASUS Tablet charger with all failing to charge. According to LG Live Chat and summary of different posts, it looks like a hardware issue. But because the device is still less than three months old and still on warranty, I contacted the Reseller (Amazon), who said that I could return the phone.
But since then I have been trying to reset my phone to factory settings (as some suggested it may help as well) and more important to get rid of my personal data. But I cannot. When I go to settings to restore to factory settings, a 5% battery is required to restore. While on charger trying to reach the recovery menu through (Power-Volume-Down then release then both again after displaying the logo) does not either work.
Any workaround how to restore it to factory settings?
I tried to connect my phone through BT to BT-ADB my phone and adb reboot it into recovery, but did not work, as my device could not get IP for bluetooth assigned!! Strange!!! My device is not rooted and I do not want to root it, so that it does not get the warranty lost.
Any workaround how to restore my device to factory settings?
Thank you!

You forget to tell us what firmware version you are on, if you aren't rooted I assume you're using Kitkat/Kitkat bootloader?
Kitkat: Hold Power + Power Down, when LG Logo appears, switch to holding Volume Up + Volume Down.
Jellybean: Hold Power + Power Down, when LG Logo appears, let go and repress Power + Volume Down.
Note that doing a factory reset doesn't really stop your data from being recovered from nosey people, it just puts your data in a "last overwritten" state. To the naked eye you've wiped your phone but to be really safe it's good to wipe your hard drive using cryptographic algorithms multiple times, about 10. It may not make your data unrecoverable but at least anyone who wants to recover your data will have a hard time doing so. I wouldn't really worry about doing this in your case though.

Thank you for your reply. I know that to totally erase my data a multi-write cryptographic erase is required. But the point is that I just want to restore to factory settings, so that notifications do not get easily read, in the case someone tried to open my phone and discovered it is still not restored. I will try doing 7-pass erase. Do you suggest an app?
Besides, your method did not work either. I am on KitKat 4.4.2. This is what I have done (while on charger, as I cannot remove the charger: 0% battery!!):
1- Volume-Down first pressed and held, then Power button pressed and held.
2- Waited a couple seconds until the LG logo appeared. Then I let go the Power Button while still holding the volume down, then held the Volume-Up.
3- The phone booted normally!!
I tried the steps again and again, and many times with releasing both buttons upon logo appearance then holding both V-Up and V-Down (after also releasing the V-Down), and still no luck
What for an annoying problem

Hello,
I have tried the search feature to no avail in regards to following the appropriate troubleshooting steps to ensure that I can at least boot to fastboot, however I cannot boot into the fastboot menu.
These are the steps I have tried so far:
With only the Power, HDMI, and MicroUSB to USB connected
1) Disconnect the Power
2) Hold Nvidia Button Down
3) Reconnect the Power
4) Release Nvidia Button (~2 seconds)
5) Press and Hold Nvidia Button (~5 seconds)
again, I am still at a black screen with no output whatsoever.
I have also tried allowing a full power cycle (where the Nvidia TV is left alone for approximately 15 minutes)
I also tried the Nvidia chat support who suggested that I try plugging in the controller and pressing the A and B buttons simultaneously, etc. to no avail.
Is there anyway to force a fastboot interaction via console? I would just like to reflash to stock. Even if this method requires altering the hardware via soldering.
You need to connect (Depending on your Model), either a MicroUSB, (2015, 16Gb, Pro / 2017 Pro), or a Male Type "A" to Male Type "A" (2017, 16Gb) between the Shield TV, and some Computer. I prefer to use a Netbook running Win7. But, This should be equally valid for Linux, and Mac.
So with you PC / Netbook turned on, and connected to the Shield TV via USB. Leave the USB style plug in the Shield and if possible yank the Brick (Wall Wort), instead.
Start a Two beat count.... 1... 2... 1... 2... (It would work better if you had a Clock that had a Second Hand.) But once you have this 'beat' drop in the Wall Wort on count Two. And THEN tap the Power Button, hold this for Three counts, than release (Pro Uses might note the SSHD will start to wake at this very moment), and immediately re tap, and hold the Power Button till you enter the Recovery Mode.
This is a very time sensitive attack, and 2/3s of the time will land you at the nVIDIA Logo. (Where available), and your only option here will be to start over again. Or boot completely into Android, and use
$ adb reboot recovery
To force the Device to reboot into recovery mode.

I appreciate your reply but again I am not getting any output what so ever after attempting to apply an update to the Nvidia Shield TV. Is there any procedure to force the device to flash even over hardware?
Depends on if you have a 16Gb or not...
Let's put it this way, if you have a 16Gb it's pretty a wrap. If you have a Pro then you have a few options. Like ripping the SSHD out of it, and attaching it inside a PC running Linux. Or at the least a PC running a live install of Linux.
Which is critical to maintain your private keys. Everything else can be discarded. But, not those DRM Keys. Not if you plan on ever using anything that will need Widevine L1.*
Now that is wholy your choice to make. Either way you will probably want to down that Torrent, which is a backup of someone else's Shield TV. It WILL reserect your Device. But, if you haven't managed to recover your own Keys you will not be able to rewrite them back later on. And, the upshot of that will be the loss of all Widevine L1 Services. e.g. Amazon, Netflix etc...**

I have the 16GB model and I am not sure what would be the best way of resurrecting my device upon a bootloader that is corrupt.
I think your forked... The only way it could possibly be done would be to pull the ROM Chip, and clone this in a not so dissimilar fashion, and then flash a working 'Image' back onto it. Before resoldering said Chip back onto the Mainboard.
Again, Not something just anyone could do.
Look I have no idea how old your Shield is, or if you still have, or have ever had any Warranty Rights to begin with. Assuming that you still had any of these 'Rights'. I would recommend playing dumb, and attempt an RMA, and pray that it works out.
If that also fails, then I guess you are what is termed as being SoL...

Thanks Ichijoe I tried to also to boot into recovery using alt + print screen + i (on an external keyboard) in order to restore the device however this did not work.
I wanted to pull the ROM chip but I don't know of any software available to allow such a feat. Does anyone have any information on utilizing J1D1 or J1D2?

This is getting oh so over my head now. So take it for what it's worth. But, as I understand it One would need an EEPROM Programer, and the "Software" would just be written as a RAW Data. Again not entirely, not unlike taking a certain 'Raw' backup that someone tossed up to the Net as a Torrent File. For bricked Pro users.
Pulling the ROM Chip off the Board is not something just anyone can do without destroying the Chip, the Mainboard, or both. The EEPROM Programmer is also an additional cost, of which I would have no clue. Needless to say, in the long run it's just unfortunate as it is, to just get a new Shield.

let's try this way :
unplug your power cable of the shield tv
plug your lan cable on your shield tv ( be sure DHCP on your local network is turning on)
plug your new shield controller on the usb port of the shield
plug the power cable and DON'T TOUCH THE CONTROLLER for 1 minute
now hold down home button and left button ( on the X) for 3 seconds
normally you can see the blue signal of the controller 3 times. this mean the procedure working good ( if not retry till it work)
now let your shield working around 2 hours ( depend of your download speed)
afetr this time, normally the shield finish downloading the update and restart... now you normally can see the screen
I have a G900T that had a smashed screen. The battery was bent as well so the phone took a serious beating.
I replaced the screen and everything is working except the home button. The phone is PIN locked so I can't do anything in the primary OS until I factory reset which I can't do without a functioning home button.
I replaced the home button just in case but that made no difference. I didn't think it would since the home button is a physical switch on the daughterboard not electrically connected to the button itself. The physical button switch on the daughterboard is working fine (tested with multimeter).
Before I rip out the daughterboard I figured I would ask for suggestions if someone has any hints. Seems odd that something so simple would break while everything else works (all other buttons, charge port, etc).
I did get a message about "check back cover" or something in the OS. Does the phone have to be fully assembled for the home button to work or something? (that doesn't make sense to me but what do I know).
It's like I'm missing something really easy. I can't figure it out.

Not very clear. You have the following possibilities:
1. Either flash TWRP and remove pin-lock.
2. Or perform a factory reset form recovery, the Home button is not needed.

You are right but seems you don't believe yourself
The real Home button is really on the subPCB, the fingerprint sensor only pushes it.
Anyway you should feel a "click" when the real button switches.

Ok, if you don't have a spare subPCB (daughterboard) you may want to remove the fingerprint sensor and try to press the Home button with something sharp enough.
But I'd try to replace the sub-PCB.

Not very clear. You have the following possibilities:
1. Either flash TWRP and remove pin-lock.
2. Or perform a factory reset form recovery, the Home button is not needed.

Is this really possible? I can't see how. There is no way to enter recovery without home button (Power + Volume + Home) and the phone is PIN locked so no way to reboot into recovery from the OS. Am I missing another technique? That would really help.
It's possible to flash TWRP without OS/root or booting to recovery/bootloader mode?

Oh, I'm sorry. My fault.
You're right, you need home button to boot Odin mode or recovery.
But if you have a USB-jig you can boot Odin mode without buttons at all. Seems you can DIY without buying.
Then you can flash a factory "full-wipe" firmware, this will erase the phone's memory including pin-lock. (but not reactivation-lock if enabled).

Thanks, yeah I haven't been able to get any jig to work on this phone. In fact I can't find anyone ever saying for sure the technique works on the G900 S5. I built my own jig as well (I build a lot of USB-OTG cables so have the parts) and tested all sorts of resistor values around 300K and nothing makes it enter download mode.

I can say it for sure.
I have a jig made by myself and it does boot G900T to Odin mode.

Huh, then maybe something more than just the home button must be wrong with this thing. I guess I'll have to pull out the board and take a look or replace it.
In the OS it does recognize the jig with a "buzz-buzz" when it's inserted/removed. Very odd that it won't boot to download load. I can't figure this thing out.

It's a good idea, I think.
Don't forget to heat everything when disassembling. Hair dryer is suitable. (Sometimes it's convenient to have a wife)
Given that the jig has only two contacts, "buzz" means that it works.
Still looks like a sub-PCB problem. Try to wash it with some alcohol.
BTW you need to power off the phone to use the jig.
Pull the battery off, insert the jig, then insert the battery and see what happens.
