Nonfunctional/broken home button (replaced, still broken) - Galaxy S 5 Q&A, Help & Troubleshooting

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.

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 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.

3-Button disabled idea.

Ok, My phone's internal SD decided to quit on me a couple of days ago, so I'm sending it back to Bell/Samsung for service. However, when I was speaking with the bell tech, he asked me to put the phone into recovery mode by doing the following with the phone off.
Hold Vol Up, Home and Press the Power Button.
When the Samsung GT-I9000M logo appears, let go of both Home and Power. (Keep holding Vol Up)
Now, I did happen to have one with 3 button modes enabled. But I tested it anyway and it worked.
Hopefully it's worth a shot if someone could try this with 3 button disabled.
Tried and no go for me (i9000m)
Didn't work for me neither..
Any Idea why the 3 buttons are disabled yet?
Wanna try the same thing, only keep holding power and vol up. Let go of the home button when the logo pops
If I Hold Vol Up, Home and Press the Power Button, I go into FORCED UPLOAD by KEY PRESSING mode, not recovery mode... what is this mode for and how can I get recovery mode? So my buttons arn't disabled, they just go into this mode. I am on JM1. Is this going to cause me problems if I have a bad flash? I have seen elsewhere that this FORCE UPLOAD mode should be accesed by vol down home and power
don't work
the 3 button combination you mentioned is the normal method to go into Recovery Mode, there is no secret there
for a moment i though it was a new combo

The normal way of doing it was to release ONLY the power button. He asked me to release the home button and not the power button. Hence me asking someone without the mode to try it. Nothing more. My phone is working and goes in every time, so I had no way to know. I apologize for wasting your time.
Ok, well i'm glad this thread is started, i was about to do it before i noticed this one!
Right well, i've spoken with an engineer yesterday at a Samsung service centre near me - and he said that the 3-button recovery/download modes has to work, as this is what they use themselves in order to flash customer handsets with their own flashing equipment. So basically, he said if the 3-button modes don't work, it's a fault, and they would send the phone back to Samsung! He did in fact add that he hasn't come across this problem himself as yet. However, he went on to say he's not sure if you could get the handset swapped out purely to access the recovery/download, as customers are not meant to be using this feature!
(By the way the method given by OP didn't work for me, and i've tried quite a few!)
Recovery and download mode work on sasktel i9000m's
hi there, i'll be getting my Galaxy S later on today, just want to ask a noob question here, if the 3 button was disabled and i tried it with the combos, what will happened to my phone? will it brick and i have to send it back to repair? or i can unbrick it myself?
thanks,

Nothing. It'll just start up normally and wont go into download- or restoremode.

ah.... thanks for the quick reply, but how come people are saying that they bricked their phone and need to send it for replacement or so?
kiay reason why people have their phone bricked is because when your phone doesnt have the 3button enabled and you try to flash your phone to another FW and it stuffs up during that time you will get a PC->!->phone pic on your screen which means it wont respond to any button presses unless you put the phone in recovery/download modes ... obviously if you dont have the 3button to be able to put them in its respective modes you will have no choice but to send it in for either a fix or replacement
hope that makes sense... thats why phones with 3button disabled will have to return their phone to get fixed where as phones with 3button active it will be hard to brick a phone

Because something happened to their phone (via firmware upgrade, changing system files, or other things) and most of the time to restore these easy fixes, we need Recovery/Download mode and it's disabled on a lot of Galaxy S's.
can some one try these buttons?
http://forum.xda-developers.com/showpost.php?p=8130971&postcount=31
when i do it on my phone all it does is bring up task manager and volume max
still disable
So, is there an alternative if the combo is not working on the phone?
coz, as i read in the earlier posts, end users are not supposed to know this...and the dealer might refuse to take the handset back for this "fault"...

Any way to save my phone?

I was running Fusion 1.1 recently, and when the Core v1 kernel was released, I flashed the 1.2ghz version, but experienced freezes.
I figured my phone couldnt handle the OC, so I flashed the 1ghz version, my phone started freezing worse. I tried rebooting and it froze during the Galaxy S boot animation.
I then adb'd into recovery and tried flashing Fusion 1.1 again, but my phone froze during the flash and now it wont boot past the Vibrant screen. When plugged into the computer, it only boots up enough the show the battery charge screen, but freezes before it even displays a battery level.
ADB doesnt seem to recognize any connected devices.
Maybe Im getting the hardware button combos wrong, as far as I know, a device that wasnt previously hardware locked cant become locked, right? I know for a fact mine wasnt locked before.
If someone could post the exact hardware button combos, cause Ive seen conflicting posts on this. Or any help for that matter, Im desperate.
try turning the phone off, holding volume up and volume down, while holding those two plug the usb cable in.
see if that gets you into download mode.

Nope, just pops up the battery screen and freezes.
A question about hardware locked phones, the combo Im using to get into recovery is, hold down vol up + vol down + power, and when the Vibrant screen disappears, release the power button, but keep holding the volume buttons.
However when I do this, the Vibrant screen just pops up a second time, which wont happen unless Im holding the power button. If I am to take "hardware-locked" literally, then the power button wouldnt even do that, right?

I just get stuck on the Vibrant screen.
Unless your Vibrant is actually hardware locked, this method should get you into download mode. I have always entered download mode using this method.
1- Power off your phone.
2- Make sure you have the correct drivers installed on your PC for the phone. (I assume you do if you were using ADB).
3- Open Odin on your PC. (I recommend using Odin3 v1.3 or higher, v1.0 has issues)
4- Remove the battery from your Vibrant.
5- Plug the USB cable into your computer.
6- Plug the USB cable into your Vibrant.
7- With one hand (holding the Vibrant on it's side) hold down the Volume up, Volume down, and power buttons all at the same time.
8- While watching the screen, and holding all 3 buttons, place the battery back in the vibrant.
9- Once the battery has been inserted you will likely see one of two things, the "swirly" thinking icon (most common) or the battery icon will pop up. Keep holding the buttons until the initial icon disappears and you see a full black screen is shown.
10- As soon as you see that black screen, release ONLY the power button, continue to hold the volume keys and if done correctly, the Vibrant will go into download mode.
11- Verify Odin sees the device. There will be a box that turns yellow with a Com port shown
12- Load up the .pit & .tar files for the stock rom and flash away. (May have to use re-partition, not sure though)
Hope this helps/works! Good Luck!

You are 100% sure you aren't hardware locked? My wifes phone was hardware locked and I couldn't get her's into download mode with that method. If you are hardware locked you may have to make a jig to get up and running....i should have bookmarked that thread....now I have to search.

I havent had to use to the hardware keys in a while, so maybe I am.
I thought you couldnt use volume keys to navigate recovery if you were HW locked?
If it turns out I am locked, do you think Id be able to access download with this method?

This kernel nearly bricked me much like the problem you're experiencing. It does seem like you may be hardware locked...it locked me out of recovery with the use of 3 hardware buttons, but luckily Odin came through.
You do have the samsung drivers installed on your computer correct? This might be the reason why you can't get into download mode. I also noticed that even though I got into download mode it did not immediately show the COM notification showing I was connected...I hit start anyway and it immediately started flashing the other kernel I used to recover (JAC OC/UV 1.0). There is something seriously wrong with this kernel on certain Vibrants and I don't think I'll be flashing it again, even after updates.

I would definitely have to agree with you there, it froze during a flash with me, which is anything but safe.
Either way, I went out and bought the correct resistors, but I've never done any soldering so I got the micro usb breakout board since its a little easier. I suppose that will come in a week and then Ill have to put it all together and see if the homemade jig works. Wish me luck!

Did your phone get hot? One must be careful when flashing oc kernel. It is quite possible to ruin your phone if the temperature gets out of control...

Good luck man. I too had Fusion 1.1, flashed Core 1.2 which caused freezes, I flashed back to stock and when attempting to reload Fusion I messed up the USB and it bricked, and I was hardware locked. I made the "Jig" and it worked fine after a couple tries plugging it in, got to download and flashed back to stock without any problems.

Strange, I release after the second Vibrant screen.
OP: it certainly sounds like you're hardware locked. And no, I don't think it means you can't navigate recovery, it means the buttons don't work when trying to get into recovery in the first place (I was hardware locked and couldn't enter recovery/download without adb; I used the flashable fix to remove the hardware lock).

[Q] Nexus 4 Damage Help

So first some back-story, I'll get right into it. I recently dropped my phone in some water. As soon as possible I dried off the outside, and let it sit. That was the only thing I could do at the time, I had no rice, no tools to open up the phone, anything. I ended up with a solid red light, and everything unresponsive.
The next day I got some tools to open her up. There was pretty extensive corrosion to the motherboard, so using some alcohol I cleaned it all off, rinsed it, and let it dry. I also took apart everything else and cleaned any corrosion. The inside looks brand new. However, this isn't the point of the thread.
It appeared my cleaning helped quite a bit. Upon re-assembling and plugging in, I immediately got a charging sign on the phone. However, after trying to power on, I got no response. Additionally, The charging signal went out after about 20 seconds, and the whole phone became unresponsive again. I can do this process as many times as I want, but the same thing happens every time.
So I tried a different approach. First I hold down both volume rockers plus the power button, and plug it in while holding them down. This puts the phone into "download mode" However, once in download mode the phone is, again, unresponsive. After plugging into my laptop, my computer recognizes the phone, but not as "Nexus 4," but as "Full JellyBean on Mako."
Is there anything I can do about this? I've heard about drivers being able to be installed when in download mode, but I would not know what these are, where to get them, or how to install them. I really don't mind if my phone never works 100% again, I doubt it would. I just want to be able to get into the storage so I can recover some of the files I lost.
It's also probably worth mentioning I have not gotten a solid red light after the clean. Once in a while I will get a blinking red light after plugging it in, but after less than a minute it stops and goes through the charging/stop charging phase I'm so familiar with. Any help at all would be appreciated, and thanks in advance.
The charging block and/or battery could be wrecked, for safety reasons and because it will probably become faulty soon you should change the battery anyway. If the charging block is broken flashing your phone could fail. It's also possible the board was irreparably damaged, but it's probably worth a try as the parts aren't too expensive.

After trying to figure more things out, I kept it plugged in for a while. It appears my battery actually holds at least a pretty good charge, as the indicator is full when I plug it in now. However, I don't know what you mean when you say charging block.
Also, I seemed to determine my power button isn't working either. I always thought no response to pushing it meant there was something else going on, but I am able to put it into "download mode" by just holding down the volume rockers and plugging it in. Is there a way to turn on the phone another way besides the power button? Also if not, will buying another power button fix the problem? I don't want to buy one then later figure out the reason it wasn't turning on was just a board problem, and not a problem with the button itself.
You can short the power button with a screwdriver or something should turn the phone on., By charging block I mean the secondary board that the micro usb port is a part of, it can be replaced fairly easily if necessary.

With a screwdriver? Enlighten me, I'd have no idea how to do that. If I had a faulty charging block, then my phone wouldn't be able to charge correct? My phone was plugged in for a while in download mode, and it gained a full charge from a relatively low charge. I also took the block apart and cleaned any corrosion, so I think that's still functional.
Some more progress, upon further attempting to turn the phone on, I was able to get it into fastboot mode. When plugging into the computer it is recognized, but as just "Android." I will type out what information is displayed here, minus serial number, as a new member cannot submit links in posts apparently.
FASTBOOT MODE
PRODUCT_NAME - mako
VARIENT - mako 8GB

Also, fastboot at the top (as far as I know) usually says "Start" or "Recovery Mode," but mine says "Restart bootloader." When I try switching with my volume buttons, nothing happens.

Now that you're at this point, have you attempted to flash the phone with a stock image? I'd be weary of what the other poster said though and ensure your USB connection is holding steady because you don't want it dying half way through a flash because then you'll have a brick.

I have tried actually. I used the Nexus Root Toolkit v1.8.0 to try and flash it. At first it wouldn't find the device, but through device manager I manually installed the usb_driver onto the phone. After this, the toolkit was able to find the phone. I attempted to flash the image, but it ended up staying in fastboot mode. The program then suggested I try to enable "force flash," which I did, and this time it was never able to finish because the phone tried to restart, but went through that "charging to unresponsive" state I described in my first post.
Upon trying to flash it normally again, it looks like maybe the phone has to be unlocked to do this properly? I then tried to unlock with the same program, but in order to do that, I need the power button to confirm I actually want to unlock the phone. So yet again, I need that power button working.
Any ideas/suggestions/solutions would be amazing.

Problem is the power button doesn't work, and the flashing fails. It looks like the flashing fails because the phone isn't unlocked. To unlock, I need the power button. Kinda stuck.

Keeps resetting..help please..

Greetings fellow geeks.
i have a problem with this i9500..
it was working fine, suddenly it resets.
it keeps resetting every 4 seconds.
won't let me go to recovery.
i can go to download mode. but it won't respond to volume button, and resets after 4 seconds.
i have a custom ram on it.
if i place a battery back in, it will power on and keeps resetting every 4 second.
what should i do?
Maybe your power button stuck in? But if you can enter download mode then not I guess. You can always flash original firmware if you haven't necessary data on it.

Ok sorry my friend, read that you can use download mode well. I think there is something with your power button. Did you drop your phone? It shouldn't reset every time in every state, that looks like hardware failure. You can easly open your phone with little screwdrivers, but you will lose your warranty. If your power button is broken you can always order new ones from China, I did it with $1,3 (power and volume).

100% your power button is stuck. Try to wiggle it lose or replace it.

TNX mate.
if i may say something, the button isn't stuck.. it's pretty clicky and sounds like working fine. is it possible the cause is coming from something else?

No it's your power button for sure.
I had that issue with my S3 LTE. It is indeed the power button since it does exactly the same that my did, try to use some alcohol in a swab and pass on the button (let it penetrate the button area, next click several times to try to clean the button from inside).
Good luck.

I have the same problem with my i9505, I always fix it like this:
1) remove the battery
2) let the phone rest w/o the battery for min. 10min
3) put the battery in and try to go in recovery
4) if you can wipe cache and try to turn it on
If the problem happens again:
1) remove battery
2) short the pins like this x/-/x/- , then x/x/-/- and then -/-/x/x (x is the connected pin) with something that conducts electricity like a metalic ring or high resistor or s/t
3) do step 3) from the previous one
(Anyways what you do is that you drain the capacitors in the phone, and on the power button, that capacitor is the main problem)
If that doesn't help, then try to leave it w/o the battery overnight
EDIT: well that is not a permanent fix, the fix is probably that you need a new power button, or in the worst case a new phone

Solved: 2nd Hand Galaxy S5 locked

Hi!
To make a long story short. I bought a second hand Galaxy S5 with a busted screen and heavily dented frame. I replaced the screen and the frame, screen works fine but after boot I found two problems:
Volume up/down don't seem to work (or the phone is blocked by the carrier?)
Phone is blocked via pattern
I contacted the previous owner but he doesn't remember his pattern (it took me two months until I found the parts I wanted and repaired the phone) and also doesn't remember his PIN. And since the volume keys don't work I can't enter neither in Recovery nor in Download mode.
The phone is being recognized in my computer, I tried to make the phone boot with adb but since it's locked it doesn't work. I guess the USB debug options is not switched on.
Is there any alternative method to make the phone boot into recovery? I'm fairly new with adb so is there is a way please post dumb-proof instructions :silly:
Thanks a lot in advance!
Just to double check you are using the correct key combo
Recovery: Volume Up & Home & Power
Download: Volume Down & Home & Power
I can't think of anything off hand, so would concentrate on trying to get those buttons repaired
Possible you have either dislodged something during the repair, or whatever damaged the screen / chassis did

Thanks for your reply!
Unfortunately this means removing the screen again, which won't survive with my basic tools, I guess I have a new door stopper now

Doesn't look like you need very advanced tools at all, a piece of plastic and a screwdriver

I had to do this with an S4 a few weeks ago, and it was very simple to get to the volume buttons without any issues, 1 minute job

To remove the S5 screen you need first to warm it up with a heat gun, the AMOLED screen is very sensitive to heat and extremely thin, I'm quite sure that the new screen won't survive my removal attempt according to what I read in the web (to remove the old one I just used a hair dryer, since it was already broken I did not need to be much careful).
Additionally I used a strong 3M double sided tape to install the new one.
The sensors for the volume keys seem to be on the frame (according to my poor visual analysis), so if I need to buy a new frame (and probably a new screen) I may end up looking for a new S5 to get repaired...

Just remembered as I was typing, you need a USB Jig, insert that into the USB port when the phone is powered off, and it forces the phone into download mode without the need for buttons
Either make your own (I did for the S4 with a dead power button) or buy for a couple £ on ebay

Thanks! I just bought two in $bay, one for €3.99 and a second one for £0.99, just in case... I'll report here how it goes...

Great, I ordered one from ebay but was going to take a week, so went to the town and bought the resistors and a cheap USB lead, made one while I waited, so I have a couple here now too
Yea let us know how you get on, if the volume keys are physically dead, I'm sure there will be plenty of apps you can use to remap volume to soft keys
I also ordered two because one is from HK, the other from Europe
(what does not rule out the possibility that the HK one arrives first)
Just thinking out loud, could it be that the carrier (Swisscom in this case) blocks a device in order not to enter in Recovery/Download mode? Is this technically possible?

No they don't have that low level access to stop buttons working before the ROM loads, they could block an IMEI, so the phone won't work on the network any longer, but not physical buttons
Download mode is available even if you wipe ROM & Recovery, nothing to do with the carriers
Ok, I got the Jig, plug straight into the phone and it boots in Download Mode!!
BUT!! I open Odin, flash the new 6.0.1 Firmware and after the reboot the S5 is asking for the pattern again!!
I guess I'm missing something with Odin, which one of the options sets the system back to its delivery status? Re-Partition?
Thanks a lot in advance for the help!
Cheers

Check the "NAND Erase All" option, should wipe the phone back to factory settings
Did that, unfortunately the S5 now doesn't boot. It freezes at the start screen, I let it "hang" for 40 minutes, then removed the battery, press the power button for about 30 seconds, put the battery again and rebooted.
It's still hanging (15 minutes so far...)

Did you flash the ROM again without that box checked, once you had done the wipe? Try that (Some people saying to flash a few times)
Next step I'd try firmware recovery with KIES
http://www.samsung.com/uk/support/usefulsoftware/KIES/
Try that, then if still having problems, try below
Flash the ROM with the PIT file for that model S5
http://forum.xda-developers.com/showpost.php?p=52329647&postcount=2
PIT in PIT section
ROM in AP
Flash together
Uncheck the Wipe NAND box first, make sure repartition checks itself once you add the PIT file
Which model S5 is it ?
