Locked phone, power button not working so no recovery, please help! - Galaxy S II Q&A, Help & Troubleshooting

My phone (Galaxy S2 i9100) is blocked. I don't know the screen unlock code and at the same time my power button is not working due to water damage. So I cant use the phone.
I attempted to fix the power button/board first with some isopropol treatment but that didn't fix the problem. I then bough a jig from ebay and managed to get into download mode. I flashed a stock rom onto it thinking this would solve the problem, but it rebooted nicely and gave me the same lock screen (and I dont have the password).
I've been trying everything to get this phone restored, but obviously since I dont have access to the software and I cant use the power button to get into recovery mode, I am a bit stuck.
My ideas here are:
- re-partition with odin if I can find the PIT file., would this work?
- find another way to get into recovery mode. (I considered ADK developer tools, but USB debuggin isnt enabled)
- flash another custom rom to override this, would that work/where would I find such a rom?? (cyanogen doesnt have md5 files?)
PLEASE help, I wanted to give this phone to my mom as she needs one, but I am not seeing the light at the end of the tunnel.

Try to open your phone. I mean open the screws at the back part of your phone, then remove the triggers for the buttons. after you remove the triggers. click the buttons many times. then bring back the triggers, and re-assemble it again. And the buttons may/can work again. I also have this kind of issue before. But I did this thing at my own risk.
Just try this thing man, I mean just try or do it at your own risk.

Thank you for your reply. I cant detach the buttons but I got the phone to work ). I still need to replace the power button though.
What I did was I flashed it over and over, I found a PIT file and flashed it, nothing happened. then SOMEHOW it gave me a start screen without the pin lock (as when flashing a new rom). I dont know how this happened, but I think it was a software error. I quickly went through the phone, doing all I could to reset it and remove all pins and passwords and enabling USB debugging, but it wouldn't let me change the pin without entering the old pin. So I downloaded quick boot, hoping to be able to reset into recovery, but I couldnt use that either, because I had lost root access by flashing a stock rom, lol. Long story short, as I was searching for answer, the phone screen timed out and locked on me again, I thought I was going to be sick. I tried rebooting it and it got into a boot loop (you can't make this up)
I then remembered that the one good thing I had done was to enable USB debugging, so the hacking began... .....I rebooted into recovery mode and couldnt do ANYTHING without the power button, lmao... It was like seeing the light at the end of the tunnel and then realizing that it was covered with steel bars. ..BUT... after educating myself and hacking a bit more, I was able to unlock the phone by using the "remove password key" command in adb. It only took me 20 hours of frustration and lots and lots of coffee and sweets. :victory: I hope my mom appreciates it .

[Q] getting into recovery, touchscreen (d2pad, rk2829)

Well, I have a d2pad SN 201301 on the back so its somewhat new
It uses rk2829 rockchip.
Anyways Ive been trying to get recovery on it for the past couple hours to use a new rom, finally got recovery working, did everything installed my rom, and let it restart.
Well, The rom isnt compatible, there was a later version a few pages into the thread that might have been, but the one I got wasnt.
So now I'm stuck, at the intro d2 logo
I only have 1 button and it is power.
Ive tried to get adb working, because it at least says its connected, but with no success anyone have any ideas?

Hey, I realize that it's been a couple years since you posted this question. I never saw any responses. So how did it all end?
Also, there was one critical piece of information you failed to share with the XDA community...you said you worked on getting into recovery with a device that only had a power button and no volume buttons. May I ask how on earth you managed to get into recovery using only a power button? Reason I ask is that I am now facing this situation. NTech Alexis RX3HD8 tablet, rockchip RK2928 processor, power button and no volume buttons! I need to get into recovery but I cannot turn on USB debugging (and the tablet is pattern locked but the pattern was entered too many times....so I am locked out).
At this point, if I cannot enter recovery mode, the tablet is a permanently soft-bricked which is, for all intents and purposes, the same as a hard-brick.
I think what happened for me was, wanted to install new rom, got into recovery to install it, then it bricked my tab, after that I was at the logo
in my case i fixed everything by getting a rkflasher, to reinstall it, and contacting support for the factory image, which is lucky they new something about it, some companies abandon support, or dont know enoguh about what they sell, lol
as for your situation
these are the things i'd try
1. If it has google play, and is connected wifi even if its locked you can try this page
https://www.google.com/android/devicemanager
and then pick ur device and factory reset it is an option (although ive never tried it)
2. search around on the internet for 1 button recovery methods, I've seen quite a few weird tablets, and some I can think of with 1 button recovery
A. a pin hole thats not the reset button or the mic, was an actual button, and that was used to get into recovery with a safety pin, and doing the normal holding it while powering on method
B.. holding the power button, and instead of letting go when u see a logo, keep holding it, till it shuts off again, then power it on
C. plug it in to pc via usb, and turn it on, while its booting, see if ur pc recognizes it at any point during the startup and try to run some commands, ive had a brand of tabs, that give u adb access during boot, but then remove it after finished booting
4. their website is in spanish, and they dont have firmware/manual links available for your tablet
You could contact support for recovery instructions or reflash instructions,, and hope they speak english or you speak Spanish
Most of the time with 1 button tablets, if theirs no info of similar ones online, unless you can contact support, you might be out of luck
PS, my edit:
also, I saw ur post on the youtube video while looking up stuff about this tablet, if that guy can get you a firmware, you have another option of trying to get to download mode too
my tablet, with rk2928 uses these instructions to get it to show up in the RKBatchTool.
https://www.d2pad.info/docs/OSFirmwareInstallInstruction_D2-721.pdf
maybe they can help you get into download mode on urs
all of this being said, I hope my first suggestion will work, IDK if wifi is disabled during pattern lock, or if u can factory reset any tablet, I just know I always see that option when I'm using it to find my devices ect.

Hey thanks for getting back to me. You've been extremely helpful and your response may hopefully be found in future by others who have the same problem.
Here's how it's working out for me with this device:
1. It has Google Play but unfortunately the wifi is turned off and there's no way to connect. But in any event, the little kid whose tablet it is (I'm working on the tablet at the request of her father who is my friend), she doesn't remember the Gmail account name or password.
2. I've searched the entire Internet (LOL) including Spanish and Chinese websites/videos but no luck. I can't find anything about putting this badboy into recovery. The reset button is just for show...it only turns the tablet off in case the power button is unresponsive.
3. I've been to the website of "manufacturer". It's a Portuguese company (I speak the language) but they haven't responded to any contact requests. And they appear to offer the firmware for the devices but download link is dead. So I cannot even get the firmware to flash it. The dude on YouTube has not sent me any link to firmware.
But the bigger problem and the key to the issue is that I cannot get the tablet to be recognized by the computer no matter what I've tried. I've tried all kinds of combinations of power button play but I never get that satisfying BEEP that indicates that there is a connection open. You see, I have the drivers for the tablet but there is no way to install them without the tablet giving the opening (even if it would come back as Unknown Device). So, I'm crap out of luck with this soft-brick.
Again, thanks for your help. After 3 days and probably 15 hours spent trying to reset this thing, I'm going to have to throw in the towel. Important lessons learned:
#1. NEVER PURCHASE AN ANDROID DEVICE THAT HAS NO VOLUME KEYS (or without knowing how to get into recovery). You're only asking for trouble if anything should go wrong. And believe me, this is the THIRD TIME I've seen a device that cannot go into recovery. In one case, I was able to flash new firmware directly on bootup off the external SD card (it was an Android laptop with WM8505 chip). I guess one out of three ain't bad odds...but they are not the kind of odds you want with expensive devices.
#2. ALWAYS TURN ON USB DEBUGGING WITH ANY ANDROID DEVICE YOU OWN AND TELL YOUR FRIENDS TO DO THE SAME. One day, it may end up being the savior of the life of that device because it usually means you can access the device via ADB in case of a soft-brick. LOL.

At last, did we find at last how to enter in recovery mode if there is only one button (power). I am in the same situation with @CVAngelo .Is it possible not to exist recovery mode at all? My tablet is BENEVE R708G with Rockchip RK2928. I tried every combination with power button and reset button but no luck at all.I have boot loop after trying to change the bootanimation.The weird thing is that the new boot animation ''works'' but after that it goes on boot loop forever.

HTC Droid DNA Screw Up -Need help-

So, like everyone else, I rooted my phone and decided I dont need all this bloatware and other nonsense system apps.
I was foolish enough not to back up things I were removing, and nothing SEEMED important, but all of the sudden my "Htc dialer": Has stopped working.
My phone will turn on, but I cant turn it off, it just reboots without actually turning the phone off when I hold the power down.
I cant get it into recovery mode ( power vol up) and when it turns on, it goes to the default lock screen the phone comes with, and then I CANT see my home screen at all. The home button doesnt work either.
I cant get to my apps, I have to use my girlfriends DNA to beam whatever app im trying to get to onto my phone.
I can go to settings, but cant factory reset.
I tried killing the battery to get power it off, but then cant get to recovery screen there either.
I'm not sure if anyone has the system apps apk's just laying around so I can attempt to repair my phone, ( my girlfriend wont let me root her phone, but thatll be the next step if no one can help) but any insight as to what I can do would be appreciated.
Try fastboot flashing recovery and then dirty flashing the rom you were on before you started deleting things. This may help you keep your rom setup. If this doesn't work then go to the moonshine thread run the ruu and start from scratch.

Honestly I don't know where to begin with your post. Its all over the place. The phone turns off by holding the power button for 10 seconds and waiting for the capacitive buttons to stop flashing. If your phone turns on its really not possible for this NOT to work. Yes it will reboot this is normal, though once the lights stop blinking you can quickly hold volume down and power to access boot loader and power down fully from there. Recovery is accessed from bootloader too assuming you have one installed. A lot can be done from both bootloader and recovery to solve problems so finding out if you can access them is the first step. I don't understand your statement about the default lock screen showing and you can't see your home screen. Which ROM is it? Which lock screen are you referring to? Why can't you simply unlock the phone? What is stopping you from doing that? Your home button doesn't work and you can't get to your apps...meaning? You can't access the app drawer? I thought you couldn't unlock the device there is conflicting info there. I don't see how you are beaming tasks one at a time through this painful process but I would just avoid that until you've fixed the problem. You can access settings but no factory reset, why? What can you do from settings? And finally you are asking for some apk's "just lying around".....dude your issues seem severe, obviously you are inhibited from using your phone right now but someone giving you some apps won't solve your problem in fact it would probably make it worse. Get into recovery perform a full wipe and flash a different ROM. Also don't mess with deleting apps if your not sure it might screw up your system.

Alright let me try to be a little more descriptive.
So as for the lock screen, I can unlock the screen, but then I see a black screen, no home page/icons. I cant get into the app drawer, when i try to factory reset, it says "rebooting" for a few seconds, screen turns off, right back on to lock screen, sim card says preparing, and then i'm back to where i was, doesnt actually reset. As for the beaming, I can say, open system app remover or file viewer on my girlfriends phone, then beam it, and my phone will open the corresponding app. This is the only way I can get apps to open, since I can't get to drawer or go to home screen.
When I hold down the power button down, the buttons flash, I get a message saying " continue to hold for 3 seconds" it counts down to 1, and then nothing. I can hold it til my arm falls off, nothing at all happens when it hits 1, I also can't power the phone down. If i try to, the screen goes black, capactive buttons turn white, back to lock screen and phone does " preparing sim" and the network/wifi reconnect as if it was just rebooted.
I have the default rom the phone came with, I believe I have a bootloader, I used a guide from this site to perform my root. The folder I have contains distiller, dnashellroot.apk, boot_secure, busybox, su and superuser.apk
dude your issues seem severe, obviously you are inhibited from using your phone right now

The weird part is, other then not being able to turn it off/get into drawer/see home screen, everything else works. If i get a text, i can drag down and select it and it opens. If i open gmail on my GF's phone and beam it, will open Gmail and function 100%. Same goes for any app we both have that I beam.
I just used my rooting method to force bootloader up, which worked, but when i hit recovery, im looking at a picture of a phone laying down with a orange triangle/exclamation point in the center of it.

Ok - fact of the matter is that you might want to try getting into recovery via the bootloader (vol down + power from off). If you can access the recovery module from there, you are then able to click advanced (using TWRP) then click sideload. You will then need to use ADB to sideload a new ROM onto the phone, then install via TWRP. Hopefully you might even still have the old .zip for the current ROM that you're using and just really need to get to recovery.

I can get into bootloader, i tried recovery, i get a verizon screen bootloader but just resets phone after a few minutes.
At my friends suggestion i just got TWIP installed and now i'm just waiting to see what she suggests next. I figured out thanks to my advance app killer I can get to the play store whenever i need to, and then open any apps i've installed through there. Stupid work around, but hey, it works lol.

Well if you just got TWRP installed via fastboot or goo manager you should be pretty well set. Download a new ROM, reboot into recovery and install. I would suggest wiping the davik and cache - possibly even the system just to give you a fresh start.

Absolutely! I first started out on XDA when I got my first android phone; MyTouch 3g (HTC Magic). I then took my tinkering to full fledged modding where I was charging to overclock, root and unlock phones. It used to be fairly profitable, now there's one click steps for everything. Glad you were able to figure it out instead of having to take it to someone! Good work!

[Q] Phone won't turn on nor enter download mode

Hi, I've been browsing the forums for people's attempts to fix a problem. At first the phone just turned off and I was unable to turn it on because it was stuck in a boot loop. The rom I had running was an ICS stock rom from hk. During this time i was still able to get into download mode but unable to enter recovery. I have tried many times to get to recovery and then tried to flash with several stock roms too. Upon failing around 10 times I moved on to a custom rom.
This one here:
http://forum.xda-developers.com/galaxy-s2/help/guide-26-12-flash-stock-firmware-rom-t2365701
The Jelly bean one here.
Upon failing from this too and unable to do anything but reset the phone and try again. I managed to turn it off... but now unable to turn it on in any way or get into download mode or recovery.
Is there anything I can try to do to get the phone to be working? What can I do?
Try a jig but understand it's very unlikely to get you into download mode. Service centre or local mobile repair shop for diagnosis (I also doubt it will be JTAG'able).
Edit - Also, search for KingRat's 'jump start' method where you try & boot the phone with just the charger/without the battery.

Hi, I've been browsing the forums for people's attempts to fix a problem. At first the phone just turned off and I was unable to turn it on because it was stuck in a boot loop. The rom I had running was an ICS stock rom from hk. During this time i was still able to get into download mode but unable to enter recovery. I have tried many times to get to recovery and then tried to flash with several stock roms too. Upon failing around 10 times I moved on to a custom rom.
This one here:

The Jelly bean one here.
Upon failing from this too and unable to do anything but reset the phone and try again. I managed to turn it off... but now unable to turn it on in any way or get into download mode or recovery.
Is there anything I can try to do to get the phone to be working? What can I do?

Don't loose hope mate...
Try remove battery and insert charger (optional)...
Press voldown+home+power button then let someone (your mother, father, brother, sister, neighbor or friends) insert the battery for you while still pressing those 3 keys...
I hope it will enter to download mode again...and report back please...
Try to use an other battery, my original one is fuked up, it does nothing.
I bought a new one and it works
I tried plugging my charger to the phone and pressing the 3 buttons and then having someone plug the battery in for me, still wouldn't start up. Also tried it with another battery i have on hand, also no luck.
You know what the options are then. Ignore people making ridiculous suggestions which don't work. My aim is to be honest with people, tell them the truth, and have them either get their phones fixed or replaced as quickly as possible in this situation (let's face it, nobody likes to be without a phone), rather than fill them with false hope & waste their time.
I think I fried my mobo while trying to flash it cause it does head up the phone without showing anything. I am going to order parts on ebay. I got this confirmed by someone at a shop near where I live, however they won't replace the mobo for me even if i do find a working one.
=) luckily this isn't my phone but my dad's who works at home and doesn't mind using an OLD OLD flip phone just for calls for the time being.
Side question, even if i replace the mobo and I get it booted but I still get stuck in the boot screen loop and unable to flash to any stock roms what can I do?
If you replace the motherboard you should fix it without further problems. New motherboard = new NAND, no more bootloop - unless you flash again & the flash is bad; you can't mitigate the risk of a bad flash, you can only do all the sensible things like making sure you're using a PC with reliable USB ports, that you're flashing the correct firmware for your device, that you're using an original Samsung USB cable. Basically, if you're careful, the risk with any given flash is very low.
So, fix the hardware problem, flash stock for your country/carrier once you've done that, and go from there.

Lenovo s860 Bricked? How to flash ROM

Hi guys, sorry if I posted this at the wrong place.
I have a Lenovo s860 and it went into a bootloop. It was stock and all so I thought that I can have my files recovered if I just bring it to a service center so they can get the files first before wiping it or maybe even fixing the bootloop without wiping the device. Well, the thing is, the guy at the service center screwed up and now, when I try to turn it on, I still see the boot screen (Lenovo, powered by Android) but the next screen is like an television with bad signal.
I'm familiar with rooting and flashing ROMs, I've tried it on my Galaxy S2 (yeah I know, it was way back), but I think things are still more or less the same: I need to be able to boot into recovery mode in order to root the device. However, when I tried the Power Button + Volume Up, or any combinations of the Power Button and the Volume Buttons, it just goes straight to the dead screen, I get no response whatsoever.
I also tried to check if adb can detect it, however, it didn't seem to be able to do so. I'm using a MacBook Pro so I know I don't have to install any drivers, I also code Android Apps so I have a background on this.
I think my only option would be to flash the ROM on this dead device but I don't know how to do that. I've also seen some posts that suggest doing some things (I forgot the specifics) while the battery is drained, so what I'm doing for the mean time is to leave the phone open and let it drain which might take ~2 days.
Does anyone know how to flash a ROM on a bricked device? Thanks for any leads.

OnePlus Nord N10 Stuck in recovery, touch not responding

I was playing with it, wanted to root it and boot into twpr, but before i could do any of that, i was stuck in recovery mode! First time i restarted it into recovery to figure out how to get into twpr, i got to this screen, entered my pin 3362 and proceded to next menues, didnt find what i wanted so i selected enter to recovery again, phone restarted got to this screen again, but now my touch screen isn't working! I cant type anything! And i cant get past it! I can sthut it down, restart it, go to fast boot mode, but everything leads me to this recovery screen again where my touchscreen isnt working and i cant type my pin or anything!
DAMN THESE CHINESE SOFTWARE ENGINEERS.... i will give my phone back using warranty claim, hopefuly those morons wont fix it and ill just get a new one.... but maybe they will just give me big .I. because i live in corrupt country where law means nothing, so i wanna try my luck here.... anyone have any idea how to fix this?
I'm a newby in this things, once i menaged to unbrick my old chinese phone elephone P something, it took days of googleing trials and errors, but i menaged to install new android version which wasnt supported by my elephone.... but microphone didnt work tho xD So yall need to explain things to me in details coz im pretty noobish, but i can menage....
Man... this sucks so much..... how bad could these engineers be, i cant be first person this happened to, and this is surely a bug that isnt fixed, and i kept my phone up to date.
Happens to me as well. You can still use the volume keys to navigate around; however, you may not be able to go back once you select something. Unfortunately the only way I got around it was by installing a diff recovery, either twrp or the pixel experience recovery kronflux uses.
Don't use twrp on this phone.
Seriously. Do not.
Also, that's not recovery. That's your bootloader menu and only works through using your volume keys and the power button.
(Side note, warranty won't cover a modified device and attempting to turn in a device that's been altered can hurt later attempts at using your warranty for legit concerns.)

There are 2 pictures, second one is bootloader, yes i navigate using volume buttons, first one is recovery that asks me for password, which i can't type, because ''screen'' stopped working, and i cant get pass these screens. Did you even read my post or just saw it with left eye and decided to type a comment so i have to repeat what i allready said?
Anyways, i returned phone under warranty, and i didnt get to root it with twpr even tho that was what i was trying to do, but phone bugged out on me beforehand. Hopefully they wont give me any problems because i did ''install'' twpr in os, but that probably means nothing as it doesnt really do anything at that point.
I was following tutorials i found for this specific phone, probably bullcrap generic articles, i wont try to root it again because it seems like a problem, **** oneplus....
But, if they dispute my claim and ask for money, they wont get any, i will ask them to return the phone to me and i will manually flash it completely or whatever, and get it working. I was refraining from doing so because its under warranty and i didn't want to **** it up.
