Hello
I've got my greedy hands on G1. Phone was free so I can't loose on that lol. Gal who gave it to me said that all it does for her when she powers it up is going into Hboot screen I applied dreaimg.nbh, got it to boot into rc29 and realized that I had no simcard in it. I powered it off, put sim in it and powered it back on and now I'm looking at Hboot screen again. I can boot into recovery just fine though but selecting reboot from that menu takes me back to rainbow. I can also reboot with 3-finger salute but again, it takes me to Hboot.
I have a feeling that this is a problem with camera button rather then software, did anyone fix this successfuly? Is there a way to physicaly disconnect camera button from main motherboard? Any insight is appreciated.
I'm not a noob, I can troubleshoot software issues but i've never taken this phone apart so I'm clueless.
Thanks in advance.
Ok, so I found this thread and I guess there's no easy way to just disconnect camera button. I still would like to know if anyone recovered from such a problem. Thank you in advance.
I have not taken the G1 apart, but I was a hardware troubleshooter for much of my professional career. My first guess is that the button is stuck not shorted. Always try the simple things first. Look at the button cover, does it protrude from the case slightly, or does it look pressed in. Even if the button cover is not pressed it, it is possible the button itself is stuck. in this case, tap it against a hard surface a few times. Hey it was a free (broken) phone, what have you got to loose. You can probably tap what would seem to be a little too hard without hurting it. If that doesn't work, then you may need to take the phone apart and check the button state. Does it push in, pop back out. If not you may be able to physically pull the button back out. If it does, then it's possible the button is messed up/shorted inside. By the looks of the pictures, the only fix is to unsolder the button.
Those are the steps I would take. Always start simple and work up from there. And always be open to something that seems unrelated that you may find along the path but ends up being the problem.
Hope it helps

I don't have t5/t6 screwdrivers handy so I did not quite take it apart. I did nowever pry the camera button (plastic part of it) out slightly, enough to see inside. I found that the actual button does work, i.e. it goes in and pops out on it's own. I tried tapping it as well, harder then most people would probably. Still the same problem. Oh well, I have one more trick up my sleeve. When I got the phone it was super cold because it was left in the car overnight (way below freezing temps, those MN winters you know) so may be I can do it again... who knows, like you said, what do I have to loose?
Thank you for your opinion.

Hello Everyone,
I have a BA and I want to flash it but the power button dose not work..opened it up and found that the mechanism under the button has dropped and hanging on by a thread. The device works but I need the power button to get into bootloader mode.
So the question is this: is there a way to get into bootloader without using the powerbutton?

From Jadel....
First, some advice. Several people have asked this question and it has been responded to in other threads. On forums, ALWAYS try and use the search function before asking. It might save you some time, and it also may give you further ideas or solutions to the problem. Now on to the response I gave someone else last year. Read the whole post.
IT IS POSSIBLE!
BUT DO THIS AT YOUR OWN RISK!!! I'M NOT RESPONSIBLE FOR ANY DAMAGED OR FRIED PDAs
I know because I myself have done it on an I-mate (Himalaya). It took some trial and error but I am now running WM6. In my case though, I had to completely remove the power button from the device. The previous owner dropped it on its head, and I got it for free, unfortunately most of the top is missing, including the power button.
SO, on to how I did it. I took a paper clip (metal) and put it about 1cm down, slightly to the right of where the power button used to connect to the motherboard. Make sure you have turned your XDA/IMATE on before doing this. You'll find that when you find the right area, your device will turn off, or the screen will go dark (like holding the power button for a second or giving it a quick tap).
If you manage to hold it there for the right period of time, while pressing the other bootloader buttons, then you will be able to enter bootloader.
This took me close to an hour to get just right, on both occasions I have done it, but it eventually worked.
Note: I have no idea how exactly this worked, but it did. My IMATE was useless without me updating the rom, so I had no worry about frying it if I did something wrong, that is why I was OK with playing around with its insides. BEWARE that you MAY DO DAMAGE to the device.
Good luck.
If you have no clue just don't post!!
First off I have searched here and the internet as a whole and your suggestion didn't work! I have taken apart and modified to add a camera to my working BA ( yeah I got 3 of them) so "..playing around with its insides. BEWARE that you MAY DO DAMAGE to the device.." is no worry of mine. Second off, if you had taken notice I have been on this board since Feb 2007 and I have only had to ask 3 questions, which means my searching skills might just be working on some level.
Maybe I should have been more specific: is there a software boot loader for the sx66?

I lifted this directly form another site I have subscribed to
http://relaysgoldens.com/sx66/tools/ROM_Update_Tools.rar
Recently I've been having issues with my power button. When I attempt to press and hold it to bring up the "Power off," "Reboot phone," etc. menu, it immediately just shuts off the screen. It isn't recognizing the long-press action. Pulling the battery is almost always the only option I have to shut down the phone. Very frustrating. Anyone have a similar issue or suggestions on how to remedy the situation? Thanks.
Well if you're trying to reboot or go to recovery/fastboot you can download quick boot from the market. Not sure how to fix your shut off screen problem though.
Yeah, I've been a Quick Boot user for quite some time. It's actually shutting down the phone that I'm having a problem with. I just can't figure out why it won't recognize my long-press anymore. It just immediately turns off the screen. Very frustrating.
I have the same problem
I tried with hard reset and different original rom but the problem persists, I think it's a hardware problem.
there's a post around that describes how to clean the power button which usually fixes it. will try to find it.

EDIT: I was having to use a Gscript to power off/reboot the phone.
Leave "su" checked and make a gscript. In it put:
Code:
reboot -p
for shutdown
don't forget the carriage return at the end.
I've been having the same problem for the past couple of days. The most annoying thing is that unlocking the phone can take several attempts.
I finally had time to try to clean the button. I took the back off and took a small brush and stuck a few bristles down the side of the power button and wiggled them around in an attempt to clean around it, then blew around the button with some air. I used an air compressor but a can of compressed air should work the same. This was 5 minutes ago and, so far, it seems to have fixed my power button problem. Hopefully it was just dirty instead of faulty.

Wow. Well, I'll have to give the brush and spray method a shot and see what happens. Thanks for the tip.

Where exactly did you stick the brush? I just got this problem :I
I realised this issue when I started using the desire rom port by Paul. I've since then switched to the Froyo build and don't encounter this anymore. Don't know if it was just a coincidence.
I've tried cleaning with a brush and compressed air, but the problem still persists. Grrr...

I took the back off and just stuck a few bristles of the brush down the button hole. If this helps you visualize it, the phone was vertical and so was the brush. The bristles went straight down beside the power button and I wiggled it around a little. I tried to get all four sides of the button, but can't remember if I was successful. I don't know if the brush actually did anything, but it's been working better after brushing and blowing it out.
I have this problem randomly... My way is to hold the power button down the whole time while pushing the shutdown button and the okay when the prompt appears!
I seem to have finally fixed my power button. Basically I just took the battery cover off and then gently pried back the plastic power button toward the rear of the phone until I could see underneath it. Then I carefully shoved a safety pin between the plastic button and the actual electronics beneath it and lightly wiggled it around a bit. I repeated this several times, testing the functionality of the button in between attempts, and eventually got it back to proper working condition. If you're brave enough to attempt this, it might work for you too.
I dropped my phone yesterday, and the power button doesn't do anything now. It doesn't seem to move much, either. I popped a little of it out using the stylus, and couldn't find any wires so I don't think there's a solution. The button itself seems fine, but I think it got dislodged a bit from whatever mechanism (spring or latch) that tells it to turn on or w/e. Looks impossible to open up the device. (don't see any screws. looks soldered in)
Anyway, the phone itself works. I resetted it and it'll load up Android fine. I just can't get into Android because you need to press the power button to get out of the standby screen.
Is there any way I could
a) assign a new button in Android (say the center button?)
b) fix the button (or if I brought it to a Sprint store would it cost less than the phone? ($60))
c) get rid of Android and go to Windows without using the power button (power+reset code)
Thanks for the help!

There are 4 Torx screws (1 under the warranty void sticker) essentially at every corner, so if you get a small enough torx screwdriver you can open it up
Here is a guide albeit in Russian, but the pictures are self explanatory
http://www.pdacenter.ru/razborka/razbor_htc_touch/
Is there any way I can reassign the button to the Back button or something? I need a quick fix so I can use the phone now for calling. Its probably built on to the motherboard because there's no wiring from the looks of it. Not sure where to find such a screwdriver, but I'll look into it.
I had a similar problem with my camera (back) button. It was a fairly easy fix. You will need a tiny Torx to get it open. There is a complete teardown thread on this site to help guide it. Once I had the right Torx driver, it took a few minutes. The switches are surface mounted and are held in place with clips. I had to bend the clips back into place and then reflow the solder joints with a soldering iron. I dropped some solder onto the clips to hold them together.
I tried to roll an alternate ROM with different key assignments...the build process is not well documented, IMO. I asked and was basically told to go make friends with a developer.
I just noticed my volume down button isn't working anymore. I don't use it very much, mostly just when I'm flashing a different rom. My first thought was "it's just a bug" so I tried using the registry editor to see if that would help but no luck (not 100% sure if correct but the registries matched what was posted). I watched a video on how to disassemble my phone and that seems to be my next step but I wanted to see if there were any other things I can try before going that far.
Any ideas?
Right now I'm on the intrinsicROM and I can't get into boot loader mode because of my volume down button so I cant just try a different rom. I read the intrinsic thread, I'm only one with this problem so I don't think it's the rom. It's just hard to believe it could be a hardware problem, could a button could go out that easily? and only down?
Thanks!
EDIT!!
I decided to take it apart, took out the flex volume button and it was easy to tell that was the problem. I ordered a flex volume button for 15 usd and now I'm waiting on the mail man. For anyone with the same problem, I watched the youtube video about replacing a cracked screen except you don't take the screen off or peel the circuit board off. All you need is the back cover off, then move some wires out of the way of the flex button, unplug the flex button, the flex button has a sticky backside so you have to separate the button from the phone using something really skinny and pull it out with some tweezers. That's how I got mine out but if someone knows a easier way fill free to share. Be careful with trying to take the flex button out, if you don't know for sure that's your problem, it can be easily damaged if being careless.
I have my Galaxy Exhibit (II) 4G for about a year and two weeks now. Warranty period is just over. I used Stock ROM in the beginning and have been using CM10(.1) roms for about 10 months.
Yesterday early night I noticed my battery suddenly diminished about 60% in 15 mins. Then I had it in the charger later, and I think I let it fall one time, like that happens sometimes. Since then my phone has been randomly rebooting and then looping either the battery sign or the Samsung sign.
Usually I can get it to boot up again with holding the power button, but sometimes I just keep pressing everything until something happens.
I can get into recovery. I tried wiping everything. I have tried deleting battery stats. I have tried other (non-oc) ROMs.
NOTE that sometimes it happens in recovery mode too, usually right as it is getting into it, so it might be totally non software related.
Do you guys think my phone is broken? Or is it worth trying to buy a new battery?
Turns out the phone thinks its on/off button sometimes is pressed, so it keeps rebooting. If I press it a couple times it's over. But then then next time there's always like a 50% chance that it gets stuck again...
Did you solve your problem because am facing the same problem. I can't even make it far enough to boot into recovery

I'm stuck in the same problem, first I thought it was a physical problem but I had to get technical assistance of an expert and he confirms its rom problem. he's going to install stock again via some freaking hardware because with my pc I couldn't. Any suggestions?
Enviado desde mi GT-I9100 mediante Tapatalk
Defintly this guy couldn´t fix it, he reinstall the previous t-mobile original firmware and nothing happens, still rebooting. Another technician check it and told me he must replace a bootloader IC, I hope it works.
Now the "new technician" couldn´t fix the phone. He told my wife that previous Rom (cyanogenmod unofficial)"must have a virus and it infected the boot". I keep thinking is a hardware malfunction. Any suggestions?
If you got the ROM from xda I doubt it had a virus. Have you tried Odin back to stock yet. If not try that first.

I dubted too, the problem is it can´t boot. I have the samsung logo, then it apears the Exhibit logo and shuts down, it keeps like that again and again. I managed to get download mode but the same, 3 sec after it shuts down so i can´t install anything.
Then ya i would have to agree that the device is defective.

I had the same problem and i use to solve it by hitting the phone from the back and after i let it fall accidently it back to normal
I have the SAME problem!!!
ok so, my phone was awesome but since this is vacation time I decided to try a new rom, It was fine but then it started rebooting all the time. HOWEVER, I was able to try other roms after several attempts and think it's related to the calibration of the power button. It tries to stay awake but when I try and press the power button, that's when the problems start. Does anybody know of a way to calibrate the power button? I think that would be the solution, in case that's even possible. If not I'll have to buy a dumbphone for I don't have the money to spare on a new phone just now...
I had something similar happen this weekend. This may not apply to everyone, but I found that after pressing the power button over the course of two years the thin plastic "arms" that hold the power button inside the case have become stretched and weakened. Went back to stock to eliminate every conceivable variable. It would continue to reboot even without touching it, with or without a case. Essentially, the power button is resting against the motherboard's power module, or rather stuck and wreaking random havoc.
I fixed it and haven't had a reboot this week by using tweezers and squeezing the posts that hold the power button arms in place tightly against the outer shell. The objective is to create as much resistance as possible and have the power button spring away from the mobo. The power button has rubber pads that, when pressed, pushes against the mobo power module, so to create more distance I filed down the pads a few mm's. If it happens again I will resolder the points and remap the keys, until then I went ahead and cleaned the solder points with a q-tip and rubbing alcohol.
Removing the outer shell takes some time to break the glue apart without damaging anything, so take that into consideration and move at insect speed if anyone considers this approach for the first time. The best reference I can spot is at http://www.youtube.com/watch?v=I3dAOv2Oke0&t=6m11s where the power button is on the right hand side of his right hand. I'll try taking photos or video if it happens again.
I'll try this
