Power button got screwed

Hey ... I have A BIG problem. My power button on my HTC TyTN got screwed. And I don't know how to fix it. Tried dissassembling and the button isn't as elastic as the other ones.
So - any underlay or whatever. Could it help? Anyone who had the same problem?
I checked it ... and the button [the small black thing] doesn't "click" ... so - what can I do with that? My warranty has expired few days ago.
Or, is there another way to get into the bootloader except OK + Power + Softreset? I wanna flash new ROM (which I really need, this one is kinda weird) and I'm afraid of doing it (just for sure if I brick the phone).

You have to take the plunge and flash the unit using RUUwrapper.
Another alternative is using MTTY.exe (or another terminal too over a virtual USB connection) to place the phone in bootloader mode among other things.
If you know how to use JTAG (I'm just learning about this), then you have nothing to wory about.

But ... it has to be connected to activesync. And if thar ROM will be bad (won't boot) or flashing fails, I won't be able to connect phone to RUUwrapper.
Or can mtty put "dead" phone into bootloader?

Yes it can. I do not remember the command right now.
NB: A 'bricked' phone will always be in bootlader mode anyway.
You can run the terminal command "r2sd all" (this works on Charmers/Magicians) (so you'll have to look up your variant) to back up the current ROM to the M2 card (using a RAW writing method) in MTTY.exe (or any other suitable terminal program).

Well, I'm still a bit scared that mtty won't put the phone into bootloader.
And can you please explain me this? "NB: A 'bricked' phone will always be in bootlader mode anyway."
If i have bad XIP or whatever, it just has white screen and nothing happens. Will mtty be able to put phone into bootloader even after this?

Same problem Here
Hi Friends,
I screwed my HTC Hermes power button while trying to fix its earlier problem.
Now to turn the backlight on ..i changed the settings and I can now use any button to bring it out of Sleep mode....
I used a program available on this site to enter bootloader.
However, the problem remains when "power button" is to be pressed.
Any advice on how to get over the "Press power button" to start the ROM flashing....

Has it just popped off the board slightly?
Does it click with some applied pressure in a particular area?
I just yesterday repaired the power button on my hermes, it had popped out from the PCB on one side.
Bit of soldering managed to re-attach the metal outer case of the switch to the PCB, all seems to be working again.

Its completely come out of the PCB... I tried but doesn't work for me...
Also, further damage has been done as the Battery connector has come off the PCB......

[Q] Going back to stock.

Hi, been trying this for a long time now. I need, for warranty purposes, to return back to stock from nand android. Unfortunately i can't get to bootloader, the tri-color screen. My phone boots directly to Magldr. My phone on/off key is broken and i need it to get to the tri-color bootloader.
My question is, if there's any way i can get the stock winmo 6.5 rom flashed from magldr. USB Flasher, or by CWM, NAND Toolkit, or any other trick so that i can get it to repair?? PLEASE BEFORE ANSWERING NOTE THAT I CAN'T GET TO BOOTLOADER, I DON'T HAVE ON/OFF KEY AND THAT KEY IS NEEDED TO GET TO TRICOLOR SCREEN
My microphone is failling and the hard keys also... need them fixed.
Thanks.

You don't need the on/off keys to go into the bootloader, just the volume down rocker.
Press & hold it, then boot up the device.

Tried it a million times... it's a no go!!! It doesn't work, try it on your HD2, push the volume down and reboot the phone by taking the battery out and back in, or by pushing the reset button. That the only way i can reboot my phone. You need to shortly press the on/off button to get to bootloader.

Okay, try to install Android. After that, from within Android reboot your phone using "Reboot" option . And while it is rebooting, keep the volume down button held.
]P.S[ I just tried rebooting from within android, and then holding the volume down, WITHOUT EVEN TOUCHING THE POWER BUTTON and it went directly to the bootloader. Are you sure your volumes are working ?

You have MAGLDR installed. Power off your phone and connect charger with Vol. down button pressed. Your phone will start in bootloader.

I guess my volume keys must be down too... they work on magldr, they work on android but i can't seem to replicate what you guys are saying. But there's no way i can do this from usb flasher inside magldr?? or inside cwm?? or with nand toolkit?? without having to be in bootloader?

Those are some solutions I have been able to gather from various threads, with the same problem :
Solution #1 :
jonas2295 said:
Okay try this :
Remove battery,
With left hand press and hold volume down,
With the other hand you put the battery back in and press AND hold the power button, so power and volume pressed and hold, wait until you see the bootloader.
This will work (at least it worked on my phone 1min ago)

Some times, Bent Battery Pins can cause unpredictable issues (However, I have not seen one like this.).
You may want to check your battery pins, straighten them delicately if they are (even a little) bent.
You could try sd card flash method?

No no no no no and NO!!!!!!!!!!!!
There is nothing in MAGLDR that can make your HD2 go into bootloader. The only this.g that can get you into the bootloader besides the external hardware buttons is the bootloader.exe that can be run from inside Windows Mobile. It can only be run from inside Windows Mobile. MAGLDR is a custom bootloader that runs after the HSPL bootloader and has no way of communicating with the HSPL bootloader.
At the OP, you may have a faulty volume button ribbon that is causing you not to be able to boot into the bootloader. Check out this thread you will see what I mean. Read post #10

I had the same problem ...
I could not enter the bootmanager in android brief button press to end a call, we moved the menu to shut down, reset, etc, the same menu that appears when you hold down the button longer to stop calling ...
This defect appeared to me after I lay HD2 due to large changes in ambient temperature ...
After a few days of research, opening, drying I removed the defect, so I pulled out and cleaned the keys below the screen (Home, Menu, Back, red and green) and wipe the foil that these pressures are the same buttons ...
My HD2 has been working for 2 weeks with no errors

It seems my phone has a little more problems than i tought. I got another HD2 with a broken digitizer,but i can reproduce what you are saying about the volume key down,no need of on/off button. I guess i have to get the courage to open up the beast.
Thanks for all your help guys.

by the way, it's not possible either to flash radio also if i can't get to bootloader??
flashing with fastboot, and .img files and what not is just for android based devices right??

Correct.
If you can't get to the bootloader, you can't flash anything.
Fastboot is only for Android.

I understand that if you are getting the phone serviced directly by HTC, they won't have a problem with you having Android on it. Buy, if you are going through your service provider, that may be a problem.
good luck

I've been to HTC service. They didn't repaired the phone claiming that there was a non original software on the phone and there was water between the digitizer and the screen. Even though none of the stickers were showing red or pink or other color than white.
In fact there is something trapped inside but it may be alcohol. I had an accident with the phone on a boat. Got wet by a wave and it must have gotten to the phone too that was inside my "purse" (it's a man purse ok?!? those bags that we guys use to carry stuff!!). I didn't noticed and instead of taking the battery at once i tried to turn on the phone... all hell brake loose. I then toke the batt of, and let it rest for a couple of days. Then burried it in rice to absorb the moisture. Then read that alcohol could "push" the water out, and splashed some near the hard keys because they didn't work and i thought that may have been salt water, or salt crystals blocking my keys.
Concluding, the phones works with a few limitations. The only keys that work right is the call and the windows keys and volume keys. And my microphone doesn't work right too. People can only barely hear if i speak directly to it and shout, and still they hear me in the bottom of a well.
I've bought another HD2 on ebay, with a cracked digitizer. Was thinking of maybe taking it for parts, since mine is in mint condition. But i might replace it's digitizer and repair the two phones. I'm only affraid to open it up because it looks very, very difficult.
Thanks anyway for all your support.

Hello, i´m an electrician and i have an idea.
Important is to dry it completely before put the Battery in.
I have opened some "normal" earlier Cellphones (not Touchscreen Phones) and cleaned it with distilled water.
It seems to be impossible to get the functions of the Hardkeys back without open your Phone.
You may try to flush out the corner of the hardkeys with distilled water to remove possible contamination with crystals or minerals that could cause block the keys.
I remain this would be the last chance before opening the phone.
i can not say what happens when you do this, normaly the componets have no problem with water, only the microphone and the cable connection can hold the moisture for a long time.
I hope i could have helped you with this idea. Please be careful it will be a risk the Digitizer is also in the bottom right corner.
if you don´t want to take the risk bring your phone to a independent (not HTC or Service Provider) Phone doctor.
excuse my bad english

[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.

Another update, just in case anyone is still listening..

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.

The easiest way is plugging the usb cable (which is connected to your computer) to your phone while holding volume down button. No need to press power button. From download mode you can boot to recovery etc with the help of your pc.

did not work

This sounds more and more like a case for Yota's repair center. If there wasn't something broken in the device one of these methods described in this thread should have worked.

Sounds like hardware to me.

I had the same issue. Left it on the table with the e-ink screen on top, came back hours later, the clock was 90 minutes behind and the phone dead. Resetting with 10 Seconds ON/OFF button didn´t work. Had to send it in. 2 weeks later got it back. They said they had to change the whole motherboard, even got a new IMEI with it. Then a few days later I tried the main camera and it did not work, error message by Android, unaccessible camera... Then by pressure on the camera it worked sometimes, sometimes only misty lines, sometimes splitscreen mode, sometimes not. Maybe a mistake by the service while reassembling the phone? Anyway, had to send it in AGAIN, got it back, sold it on ebay with 130 Euros loss and bought a new white one because I love the principle and options of the second screen so much. The white one is a newer batch, they say with some new (and probably more reliable?) hardware, so up until now I am completely satisfied, no error for 6 weeks (fingers crossed...)
My old black one was maybe a monday batch

Hi Petra. Since you're using a Yotaphone as well, could I ask you to do a small favour for me please? After I had my YP rooted I accidentally deleted the system app "back screen manager". My back screen has stopped working since then. It'd be fantastic if you could just extract the system app from your phone and send it to me so that I can manually place the system app on my phone root folder. You don't have to root your phone for this. All you need is an App extractor from play store. And it will take less than 5 mins to extract and send it to me(Assuming that you are well versed with android OS). Here's my email address [email protected] or you could send me a link to the shared file. Do let me know if you are willing or not. Thanks a ton.

Nonfunctional/broken home button (replaced, still broken)

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.

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.
