Possible 3 button recovery fix - Captivate General

I hate linking other forums but since it hasn't been discussed much here check this out before returning your phone.
http://forum.xda-developers.com/showthread.php?t=785201
Its a bell I9000 fix and it has also been posted in the Vibrant section, so this might be what all of you need that have bad bootloaders.

will this work for our captivates?

No. Not yet at least. You will most definitely end up with a brick if you try it.
We should also be careful about calling this a "fix". It is more like a patch. It is being speculated (http://forum.xda-developers.com/showthread.php?t=787638) that the defect is at the PCB level (i.e. hardware). The theory being that there are minor variations with our 3 button disabled devices that prevent the hook for the three button press from registering at precisely the right time during the initial boot and therefore it is not recognized. Note that this may also explain why heating up the phone in some circumstances will allow the 3 button method to work briefly. The theory being that by heating it up, the timing of certain physical events (think electrons and voltage changes) is altered ever so slightly which is just enough for the hook to register during initial boot.
The patch hooks the 3 button press later in the boot process (either BML2 or BML4). That means that if anything gets screwed up in the boot process before the patched hook is registered, you could still end up bricked. You could also unintentionally undo the patch if you apply firmware that overwrites the initial boot files.
Edited to add distinction between fix and patch.

This is a useless thread...

Rooting VRALG1 firmware?

My brand new unit has updated VRALG1 firmware and VRLG1 radio. Knowing the original "Root66" was built from VRAF2 firmware, I'm thinking I'm stuck - for the moment, right? I *could* downgrade the SYSTEM.IMG to the insecure Root66 (VRLF1), but still hardware version 10, just like the first ones shipped on "Day 1" in North America.
Any suggestions, folks? I've not found anything specific to rooting VRALG1 firmware, yet. Everything seems to be VRALF2-specific.
This method has worked on VRALG1. I have not tried it personally because I got my GS3 a while back, but others have had success according to the thread. If you're concerned about it, you could post there.
http://forum.xda-developers.com/showthread.php?t=1792342
Just wondering what kind of stuff do you really lose in downgrading? I downgraded so I could get root and I haven't noticed anything different except for the fact that google search can now search contacts, apps, etc.
I've posted this in other forums recently..flashing modems/radios aren't suppose to change anything.... you could always Odin back to vralf2 then flash root66...
But if it were me... and I'm not responsible for bricking your device... of course... try noSympthy's newest OTA. If you check out the post it will tell you what to do for your firmware...

I bought a new phone back after a mandatory download the results of firmware phone to die
Thanks, folks! I eventually found the rooted ALG1 system.img and rooted late last night. The ONLY thing that I have found different is the "dumbing down" of searching to use only the Internet. You know Apple has a patent on that, and Sammy is keeping up a good front to comply.
There might be small changes elsewhere, but that's the only noticeable difference - so far. The phones they are shipping new now contain the updated radio (VRLG1) as well as the updated firmware.
The last one I got reconditioned had updated radio, but not firmware.
This one has slightly less exposed buttons for power & volume. Of the three phones I've returned since day 1, two had lost their power button and one had the volume rocker fall off. The other just started rebooting every 5-10 minutes, even in "Safe Mode". I haven't seen that posted, just hold the power button until the blue Samsung logo shows and then hold the volume down button, letting go of the power button after a few seconds until it boots. "Safe Mode" will show in the bottom left corner for a moment and only things pre-installed will run, programs and widgets you have added will be missing from the screens.
If it doesn't work then, next step is a factory reset...

Replacement touch screen unresponsive

I'm fixing an infuse for a friend who needed the screen replaced simple enough job so I thought as I repair phones and electronics as kind of a hobby. However the replacement screen isn't responding to any kind of touch at all. It displays the puzzle piece lock screen and everything else even shows there's been some missed calls ect. yet will not respond to any kind of touch. I think it's a calibration issue but I can't get passed the lock screen so there's no way to change the setting. Honestly I'm most worried about all the media on the phone most (pics, videos, contacts, ect )
If there is a way I can retrieve that off the internal storage I'll feel better about taking drastic measures. Other things I've noticed is an unusualy long boot up time hanging at the white Samsung letters but this is the first time I've dealt with an infuse so I'm not to sure on that.
Any advice is appreciated.
Thanks,
s1im
There are different versions of screens or maybe it was revisions. At least for the LCD +digitizer assembly. Rev.6.1 and 6.2 and 6.3 if I remember correctly.
Edit....here is a link for reference, also two of the screens were interchangeable but not all three. Sorry I don't remember which ones.
http://item.mobileweb.ebay.com/viewitem?itemId=180914982430&siteId=0&isClassified=false
Edit....my statement regarding interchangeability may not be true. The screen I bought could be used as a replacement for two of the rev numbers. That could mean that it is backward compatible but the other one isn't forward compatible.
The link said this item has been removed, but to be clear your saying not all revisions of screens can be used as replacements that you must find out which rev your original screen is?

Correct mine had a sticker on it.
Bummer I have no idea what kind of screen she had I threw it away as a jumbled mess is there any other way to find out what screen it was... either way thanks for the replies
Wish I could answer that, but here is another screenshot. It shows one for 6.0/6.1 and another for 6.2 so my original numbers were off. Did the new one say what it is?
Do you know of any way to retrieve the pics and other media off the phone without being able to unlock the screen

Just guessing but maybe adb. You could try to edit the title of your thread or start a new one about this question.
Edit..I have an idea but first a few questions , is this phone stock, and would you be comfortable flashing a kernel if it is? This will give you CWM recovery which has mount USB storage as an option in it. All this can be done with the physical buttons, power and volumes.
I found something that may work without having to make software modifications so I'm going to try that first and if not I'll get back to you...
To answer your questions tho the phone is stock and I've rooted /flashed a couple phones with no problems before so I'm OK with giving it a try
Again I'd like to thank you for your continuous help
You should be able to pull everything you need with adb...but the problem is, is adv enabled? And can you pull a whole directory? I doubt you know individual file names for each media file, not to mention that would be a long tedious process as there are likely well over a 100 if not in the 1000s of music/pics/vids
Well..looks like you can pull a whole.directory (sdcard)
this thread may help http://forum.xda-developers.com/showthread.php?t=744454
Btw...you don't have to be rooted to adv pull

UPDATE: I took the phone back apart finally after some grueling hours of adb research that lead me almost in circles and found that the replacement LCD is a rev 6.2 and that the revs 6.0/6.1 are the universal more common screens in the u.s. infuse. I decided to return the screen and get the other rev in hope it will be that easy...
I'd like to thank the 2 above members that gave me help especially adfergurson for sticking with me and my ?s I will post back when the next screen comes in to confirm it worked for anyone else needing this as future reference

ADB was the first thing I thought of, but flashing a kernel with custom recovery in Odin should allow you to get into USB storage. I am not familiar with the stock recovery but you could see what options are there. I believe it would be from device powered off hold volume up+volume down+ power buttons then release power at Samsung screen.
Were you able to resolve the screen issue with the different version? I am having the same problem.

Dropped my phone, won't boot?

Been a watcher on the forums for awhile, now I actually had to sign up and get some help, LOL.
Anyway, dropped my s2 skyrocket, noticed that it kept trying to reboot every now and then when I used it the same day. The next day, I plugged it in in the evening, and shut off, rebooted, but the screen would go black and the phone would vibrate with 2 seconds in between vibrations. It gets to the "Samsung" word, then the screen goes black in the style of an old tube TV (with the thin white line at the end). Then the vibrations start. So far a useless phone. Took it apart and checked connections carefully (I'm used to working with processor boards quite a bit).
What do you guys suggest? Damaged memory? Should I attempt to reflash? Stuck power button (seemed ok, though)? Bad screen?
Well, probably some kind of physical damage, but hard to say. Anyway, you posted in the forum for SGH-I777 but you have the SGH-I727, so I would suggest that you look in the correct forum.

Oh, thanks for the heads up. Yeah I just figured out that the i727 isn't in "Top Devices" or "Legacy," so you have to go to all forums. Ugg. Already moved. Thanks to whoever notified mod.
Anyway, yeah, any help would be AWESOME. What physical damage would prevent booting past the "Samsung" screen and default to a black screen that intermittently vibrates?
I'll be honest, if ur asking that question probably something u don't have the current skill set to fix. Try to Odin back stock, but if it started post-drop you may be SOL and in need of a new phone.
Got it into download mode after multiple failed attempts. Each time I would get it into download mode, the screen would shut off after about 5 seconds of being on. I tried several combinations of plugging it in first, then installing the battery, or holding down the button while I plugged it in with no battery, etc. I had just given up after getting it into download mode briefly for the 20th time, when I gave it one more go while rocking the on and off button. Technically that is recovery mode, but I let off right before plugging the phone in and it hit download mode and stuck.
So what I am thinking is the power button got jammed internally. I have heard of it happening on other forums. Even though it looks good and clicks upon external examination, the pressure circuit on the inside might be in contact. Anyway, just one theory.
For future though, I did discover that you don't HAVE to have the USB unplugged prior to getting into download mode. On the contrary, a power source must be present in order to register that the keys are pressed PRIOR to initiating USB input. Thus, you can actually remove the battery, plug in the USB (power source), then hold the volume keys while replacing the battery. Goes into download mode that way, too.
Will keep you guys updated. Might need a bit more help if the phone starts acting up again.
At this point, if the Download mode still holds ok, should I consider CyanogenMod, or is it easier to get back a good ROM from stock?
icenight:
Thanks for the reply. I don't understand much about smart phones or how they work, but trust me when I say I have had AMPLE experience with electronics, circuit boards, hardware, etc., particularly in the computer/laptop world. I code quite a bit of websites, and understand almost all things networking and OS. Just never really got into it with the phones.
Getting super excited to see the sheer amount of modding you can do though. Would love to break into a hardware modding world if it ever comes available. That's where it's at with electronics for me.
Well glad u got it sorted, lucky guy you are lol.
As for boards and the like, if it didn't work I would've suggested replacing the motherboard and/or power daughter board. But for a skyrocket may not be worth the money.
Since you're a hardware guy, maybe mess around with the phone and JTAG? Finding a way to unbrick without it would be very helpful
Since the problems started after a physical damage (fall) , I wonder how would Odin or wipe and flash might work !
Definitely a hardware damage...
Yeah, it kinda puzzled me, too. I believe the power button might have been internally stuck, but that's just one idea. Could have been a loose connection, too.
Can you lose some solid state memory with firmware on it, but the SS memory still be OK to right another copy on?
More than likely it was your power button

Nexus 5 restarting regardless of ROM

So I've tried factory wiping and installing a few different roms and no matter which one I go to I keep getting these random reboots. This is particularly troubling when I restore an older rom that I know I was not having this particular issue on.
It is making my phone pretty close to unusable since it will often go into an "Optimizing apps!" speil draining battery and taking an obnoxiously long time to reboot. Not sure what is up. Any suggestions?

Try with a clean flash (or the factory images) without user data/modifications and see if your RRs are still there.

The button will NOT seem to be stuck, even if it is, as the contact is made internally. My bro´s Nexus had this problem, and by the end it kept rebooting constantly because the button was making contact on its own. I fixed it by tapping vigorously at the area between the power button and the camera and that made it work.
A way to know if it is stuck could be to press the volume down key as soon as it restarts, if it goes into recovery, then there is no doubt the power button is stuck.
Don´t dismiss hardware problems, as many Nexus are affected by the power button issue and you already tried software solutions which didn´t work.
Hope you sort it out. Remember to use an app to avoid pressing the button so much, such as when waking the device. I recommend Gravity Screen, but there are many other options.

Holding down volume after one reset actually put me into recovery. Plus it's restarting at times in recovery now :/
I doubt it's under warranty since I got it in feb 2014 x.x

If you got it directly from Google, I'd try calling them up and asking for a replacement even if you are a few months off the warranty period, I have read some stories of them honoring warranties in order to get rid of stock. That'd be true even now that the new Nexus is supposedly releasing this year. Nothing wrong with trying, you might get a new, shiny phone.
That being said, don't worry, it's perfectly fixable. The part that gets stuck is not the button itself, but the part that goes into the motherboard, so don't bother fiddling with the black button. I managed to fix my brother's button by doing the following:
- Clean the area between the button and phone of debris or any dirt that could be causing it to be stuck. This is just to be on the safe side, as it is unlikely that it is the cause of the malfunction.
- Take the case off the phone if you haven't, and then put it upside down and tap vigorously with your fingers in the area between the camera and the power button. It might not work the first few times, but it eventually will release the part that is stuck.
- As soon as you can get it to turn on without rebooting itself, install Gravity Screen, or any other app that replaces the power button to wake up or turn the screen off. You are looking to use the button as few times as possible.
After doing that, his Nexus went for being unusable due to constant reboots to working fine. It's been almost 6 months since it happened so it is bound to work, just don't lose heart and patiently work at it. Tap a bit harder if it's not working. Let us know whether you managed to fix it.

Well someone mentioned maybe trying to clean it out somehow. I tried canned air and that didn't do anything so I formed a seal over the button using my mouth and then proceeded to exhale. It has yet to give me any trouble since then.
Had exactly the same issue, reboots over and over again, couldn't boot to bootloader without reboot...
What helped for me was something I read somewhere else, don't remember where, was knocking on the back cover between camera lense and the power switch, did it 4 days ago and it works since than..

You can take the back cover off, and if you are careful there is no sticker or seal that would tell google you have opened the device. It is difficult to pull all the way off, the vibration motor is attached to the case back and comes off with it so it would seem stuck. You just have to keep pulling.

Yeah but you'd need to unscrew a plastic cover that is inside the phone. Phillips head screws, jewelers screwdriver size. Depends on if its dirt or a broken switch though.

Sorry to disappoint everyone but this is a widespread problem that google is aware of fro some time now. It's not the power button but it's burried deep in the software and appreas to have popped up right after the Lollipop 5.1 up date. Check out all the posts on Google

While it apprears to be confined to the Nexus 5 I have had it happen with my nexus 4 just running stock L 5.1
I hope that casts some light on it
Weirdly enough, my power button works flawlessly on 5 and 5.1. Red 32gb from the google play store. I've opened the case multiple times and put Arctic silver knockoff heat compound in sloppily and without regard, no issues other than sprint screwing up their spark LTE rollout.

Sorry, I disagree. While some instances might be related to software, it has been proven that there is in fact a problem with the physical button getting stuck on Nexus 5 phones. You can check it online and will find lots of hits and even YouTube videos, most of them around the time before lollipop.
Best way to check whether it is software or hardware is to press the volume down key when your phone reboots by itself. If it takes you to the recovery, you can bet your cat that it is not lollipop's fault
So I'm suspecting that I have the wonky power button too but.....
I haven't been able to get it to go to recovery when pressing power down and I've defintely had a few restarts very recently.
More importantly, and something that I haven't seen anyone else post about; more often than not my N5 just shuts down. It's usually when I've doing something with the phone (today was flicking through my GPM library). I'll power it back on and it will boot cleanly and then (more often than not) power down again. Other times it will bootloop, but that's rare. It seems to me that if I let it boot up and then don't touch it for a while, it will stay up but I'm not sure that's consistent.
Anyone else seen or heard of the power button causing a powerdown instead of bootloop?

You will need to troubleshoot this the old-fashioned way. Have you installed any updates, apps, mods or anything recently?
Best case scenario would be that you flash a stock image without restoring apps, kernel or any mods. Run the phone for some time, couple of days or so, and be on the lookout for power downs or reboots. After that, you can try adding a few apps at a time and keep checking. If the phone reboots even with a clean factory image, then I'd have to say the hardware is faulty. Could be the power button, could be something else.
Try it out and let us know

Xz premium freezing and resetting when i unlock it. Also no volume up, related?

Hey Guys so i have searched high and low for a solution and still can't figure out a fix. i've read on sony forums that other people experienced the same issue but can't find a fix. I got the phone second hand (risky i know but i took a gamble) and it already have android pie. At first it was working great and i was quite happy with the phone but as i started using it every now and then it would reset itself at random, even in my pocket, then it started freezing when i unlocked it and eventually reset and work again for a bit. from the start the volume up button was not working but i can deal with that. on other threads i have read that some people are having the exact same issue. Help is very much appreciated.
So far i've tried turning off fingerprint unlock, uninstalling apps, turning off auto brightness, turning off the code unlock, factory reset, flashing to android oreo, and running in safe mode and so far none of that has fixed the issue. (although it helped temporarily giving me false hope!)
i'm going to try flashing back to nougat as a last resort but am not going to have too much false hope. Thanks for reading and any help in advance!

So far i've tried turning off fingerprint unlock, uninstalling apps, turning off auto brightness, turning off the code unlock, factory reset, flashing to android oreo, and running in safe mode and so far none of that has fixed the issue. (although it helped temporarily giving me false hope!)
i'm going to try flashing back to nougat as a last resort but am not going to have too much false hope. Thanks for reading and any help in advance!

You pretty much ruled out a software issue by reverting back to Oreo and all that.
Volume rocker isn't something that just fails on these phones, so that's suspicious to me.
In most cases freezing/rebooting is caused by a faulty current supply (battery) and distribution (conectors, cables, capacitors...), if the software issue is ruled out. Faulty screen, screen connector and cable can cause freezes, the phone itself doesn't freeze up, but the image on the screen does, so it looks like the entire phone freezed, but it didn't, just the screen. Again, this as well can be caused by bad power delivery to the screen.
I would take it apart, take a closer look at the board, connectors, possible corrosion and dirt on capacitors, and replace the battery since it probably hasn't been replaced ever, and it's now a fairly old phone, and second hand, god knows how was it charged and treated in general.
If you never opened a phone before, I wouldn't suggest you start with this one, it's not really "novice friendly". Take it to someone who does board level repairs.
My best bet would be the phone was opened and some service has been done on it, but not properly+bad battery/battery connection.
Volume rocker is very easy to mess up, if you don't reseat it well it can fail to register pushing the button.
There really isn't a simple straightforward answer to you issue, if the software is 100% ruled out, the board and battery needs to be checked out, specially if the phone was opened before.

Thanks for the comprehensive reply, so would system ui not responding also be due to the hardware? I just thought it was strange that some other people had posted pretty much the exact same issues.. I'll start looking around for someone to pull it apart for me. I've done some screen repairs on one phones but I'm not willing to screw this one up so I'll find an expert!

Ofcoruse, mostly power delivery. If for example the cpu or the screen isn't getting correct voltage and power, it can missbehave or freeze up as a failsafe to prevent damage.
As I said, I would take a look at the board, and change the battery with a known good one, since I have spares lying arround, to eliminate that variable as well as software.
I presume you're not rooted and you're troubleshooting using oem firmwares. If not, all bets are off.
A faulty battery can be a culprit of many issues that look like software/ui issues, but they're not.
Make a full software repair with latest official version, if it fixes nothing, it's a hardware issue.

Thanks very much, I'll give that a go first!
If it fails where and you are close to me (Melbourne Aus) how would you like a project?
I share with you my personal experience.
The phone is amazing, is very fast, efficient, amazing sound, amazing screen.
I have the same problem with the volume up bottom but in my case it was caused for a fall incident, I took it apart and I discovered there is one flex connector that goes from the mother board and is shared with the volume bottoms, the power- fingerprint sensor, the camera bottom, the lower speaker and the lower microphone.
In fact due to that fall I am having problems with the volume up bottom as I wrote, the lower microphone, the lower speaker and sometimes the fingerprint function does not work.
I think is still worth having the cel phone, I`ll search for the flex to fix it up
I think most of the description Zagreb does of your case can be adjusted to the reality of what is happening, I think is necessary a technical checking of the hardware.
I'M sorry, of course I meant buttons and not bottoms!
Freezing, unresponsive ui and volume buttons not working properly.
I've had this same issue for a few weeks tried hard resets safe mode, etc, nothing helped. So after much frustration searching forums to no avail I set to and tried a deeper investigation into my own device, I accessed the dev options and looked at power hungry services. The most hungry was Xperia home so I stopped it and low and behold my phone hasn't locked up since, still volume buttons are mostly not working but I'm not locked out any more.
Same here,
First randomly reboot, after factory reset randomly system UI failed constantly , very annoying.
Indeed button up volume is not working (properly).
Someone found solution for this? I already purchased a new battery.
@Chernob0g : how you disabled/stopped Xperia Home so I in meantime can use my phone.
Replaced battery, looks better now.
Volume up still not working, but freezing looks solved.
