Nexus 4 hardware reset (recovery mode) entry the real way. - Nexus 4 General

[Q] Bell user - Phone switched off to enter 3 button recovery mode?

I read something in one of the other threads about the 3 button issue that the phone needs to be switched off before you can get it into recovery mode. I queried what this person meant by "phone switched off"... if he meant the device itself (which makes no sence) or if he meant that the phone needed to be in "airplane mode" with NO signal to get into recovery. I have not gotten a reply yet but here is why I ask this...
I have been to many bell stores who are out of stock on the actual devices themselves but have the instore display models and EVERY one of the display models I tried went into recovery mode EVERY TIME with the 3 buttons. Now obviously these phones dont have any signal to them and ALL of them went into recovery mode with no problems.
Hmmmm... Does ANYONE have any feedback to provide here?
Seems I may have misread the other thread as now I see that they were talking about download mode and not recovery but I am still wondering about this being a possibility as to how we can get into 3 button recovery. Samsung Mobile Canada on facebook says that they are working on a software update to fix this issue so I wonder if this could be the cause of this issue?
Still curious... Any ideas?

[Q] Pattern lock -> Too many tries

I was playing around with the pattern lock and eventually got the 'Too many pattern attempts!' message, with it asking for my Google username and password to log in.
No matter what, it doesn't accept my username/password. I am 100% sure I've typed it in correctly.
This bug has been around for over a year with many people reporting 'bricked' phones without even doing anything particularly naughty with their phones.
This is the Google bug that has been posted on it: http://code.google.com/p/android/issues/detail?id=3006#makechanges
As you can see this has been around for over a year. The 'null'-in-password trick doesn't work, nor does the spamming-home-button trick.
My phone is rooted and with the Voodoo Lagfix-only custom kernel. Any suggestions?
Do a hard reset / wipe. That's my suggestion.
Try booting into recovery (Home Button, Vol Up + Power), and resetting your cache and wiping it. Then try logging in with your Google account. If all else fails, try changing your Google password on the PC then logging in on the phone. And then if it still fails, looks like you need to flash the phone again. Next time, don't enter the thing wrong! Stop rushing haha .
I wasn't rushing, I was playing with the lock. It takes about 30 times before it's permanently requiring the username/password. But really...you can't blame me for not expecting this. :/
I'm currently trying to flash a new ROM but I've run into another problem - I can't get it to boot into downloader/recovery. It's not the lack of the 3 button combo - I've managed to reach Recovery and Downloader ONCE each in the past, but never again since.
And now with all my efforts to boot into recovery/downloader, it now cannot boot into normal usability mode (or in my case, locked mode). Instead, the Galaxy S logo loops endlessly.
Sigh.
Have you read the thread for the fix for Galaxy S variants that are lacking the 3 Button Combos? It's in Android Development. Maybe try that? Or, can you still connect the phone and connect with Kies?
I can't turn on the phone anymore, meaning no changing to USB debugging etc. And I'm having problem accessing recovery/download, even though I definitely HAVE done each of them once before and therefore do not have the 3 button problem.
Without turning on my phone, Kies can't detect it
So what happens when you power on?
Now, it shows the first Galaxy S splash screen, then shows the boot logo, then nothing. The boot logo continues to glow endlessly.
Be patient, i waited up to five minutes. If you see the s logo glowing/shining youare ok

Yeah it's continuously shining. Haven't left it for up to five minutes though... And even then it probably won't help since I'm still locked out of the phone, and unable to access download/recovery mode to reflash it.
After waiting for a long time, the logo disappears, screen goes black. Menu and back buttons light up. Nothing else.
Looks like your going to have to reflash your phone again. Download the desired firmware, open up Odin and put your phone into download mode and start the flashing procedure. Be more careful next time.

Good advice considering he said his 3 button combo stopped working =))
All I did when I got that black screen was adb reboot recovery and wiped and phone bootedup fine. But only if you have debuging enable and and sumsung drivers. Hopes this help.

Ok i did the same thing, and spent hours googling.
Tried the key combinations to restore, but never worked.
Heres what worked for me, but, be warned all your contacts will be lost if stored on the phone.
From another phone, call your locked number.
Answer it on the locked phone, then hit the "back" button.
This gives you full access to the phones menus etc.
Hang up on the phone you called from.
Now, go into Applications / Settings / Privacy / Factory Data Reset.
This worked for me whereas all other methods did not.
Once your phone is up and running again, be sure to create your google account on your phone.
That way your protected again. If you didnt previously have the account set up from your phone, like i didnt, then you cannot log in of course.
This works...give it a try. Hope it helps.

dear friend dont worry or panic... i'll tell you a trick , go to the samsung customer care and tell them that your phone gets heated up very often and today it just refuses to boot up normally...
since your device cannot get into recovery mode or download mode the company will never know that you had played with the system files in the device or not... (rooted )..
since the samsung people will also try to get your device in recovery mode.. but when it will not go to the recovery mode you will get a mother board replacement under warranty.....
this heating up of the device is a common problem in the galaxy here in india.. so use this excuse and i know it works 100% ... (just dont tell them that you had rooted and lagfixed your device )
What you describe sounds like a very large security hole if I am reading it correctly.
Are you saying that even if your phone has been locked out from too many lock screen failures, that just answering an incoming phone call gives you full access to the phone? Really?
I just checked on my phone and while I can answer an incoming call while the screen is locked, if I hit the back button or menu button, I just get the lock screen.
I'm missing something here...

UNBRICK your SEMI-BRICKED Galaxy S - Solution

Hi. Just a few hours ago while I was on my way home, I was browsing some news feeds with my SGS and I noticed some lag so I thought of restarting it, but to my surprise.. it was not booting anymore and it was stucked displaying the "S" screen then after a while it will go black although the buttons are still lighting up but there is no response or any activity in the screen and the only way to turn it off is to pull out the battery.
Upon getting home, I browsed the internet to find similar cases with most of the suggestions on how to "fix" this was to bring it back to Samsung Service Center and I'm not ready yet to do that so I dug in deeper to research. I just want to share the steps I have done to UNBRICK my almost Semi-bricked SGS.
First of all, my SGS doesn't have access to the 3 button mode recovery (Volume up + Power + Home) thus basically leaving me helpless because I cant reformat my phone from there and worst, in this case, my phone wont even boot up.
Secondly, it was fortunate that i had my phone rooted prior this.
Now, the process:
You should atleast have:
* KIES installed
* Android SDK
* USB Cable
First thing I did was:
* Connect my phone to the USB cable
* Turn phone on
* Wait for KIES to detect it and for windows to install necessary USB drivers (my phone was detected by KIES even if it was hanging in the "S" screen)
* When everything is done, go to COMMAND prompt in windows
* Locate where you initially placed the ANDROID SDK then Tools folder by typing it, example: (C:\Android-sdk\tools)
* when you are already in the right folder type in ADB REBOOT RECOVERY
* Check your SGS and it should be rebooting to the RECOVERY MODE wherein you will now be able to select format options
* move your selection by pressing up and down volume keys
* confirm your selection by pressing home key
* then reboot again and presto.. your phone should be up and running again
Anyway, if you cannot access the recovery mode by using the 3 button process, it could probably because your operator intentionally locked this feature out. There is a fix I found from XDA that works search for : 3 button mode fix
Hope this helps and drop me a message if you have queries.
By the way, i'm trying to restore my apps again so ciao for now.

you forgot to mention something
You must have USB Debugging mode set to enabled before hand, before all of that happened, else if you simply plug the USB cable to the PC with the 3 button disabled, there is no way for it to accept the ADB Reboot Recovery command
The next best thing is as many have commented before
It's to use a hair drier to heatup the phone to get access to the 3 button recovery, for those that got stuck before installing the 3 button recovery fix
also forgot to mention that this has been asked, posted, discussed many many times already. i am glad, however, that you got your phone to work
but he has it listed in a very nice an easy to read format, compared to the other ones we have seen previously
my phone did that a lil while back but i have an early ship date phone there fore i have the hard ware recovery option but this is late coming how is it that every one always says to use odin to recover a bricked phone yet i guess im totally noobish but what good is a back up recovery tool if you cant mount storage

Hello guys
I was trying to unlock my vibrant(i was messing with my nv_data.bin) and then all of a sudden it rebooted and i couldnt connect to my service. It keeps going on off on off. My data doesn't work too.
Any thoughts on how to fix this?
THANKS (
Just restore the backup you made of nv_data.bin. You did back it up before you messed with it didn't you?!
Thanks vincler.....
you solved my problem. i made the jig after 2 months but i did it.
i combined the resistors with no solders and just touch the pins with my hands and i got download modes.
thanka again.
i must see how u did this witout soldering

It worked to recover my I9000 that was stuck in the "S" startup screen!
Thanks for sharing the idea; I didn't even thought that adb would work if the phone was stucked there (I thought it wouldn't finish loading it)
oh man mine wont even boot PLEASE HELP!!!!

K01A - Lancher (and other system apps ) are dead (?!)

Hello Everyone!
I got a Asus K01A tablet from a friend of mine.
He said it "only show black screen" so I naturally thought it got bricked but he wasn't mess with it at all.
And now I'm facing with the strangest thing I have ever seen!
The tablet boots up properly. but it seems like the launcher and the rest of the system apps dead.
Battery, Wifi visible at the top, the bottom icons are also visible (home, back etc), you can drag down the quick settings bar and even (strangely) start the calculator app (?!) from it, but everything else (sadly this includes settings as-well) won't start. (Tap than blank black home screen)
I think it runs the stock 5.0 android.
I booted up recovery mode (stock recovery) but it won't able to restore the device (it starts and after a few seconds it say: "Error!")
I tried to connect to it via adb but it won't show up I guess the developer mode is not enabled on it.
(also it say "connected as media device, but I can't do anything about it cause nothing happens when I tap on the notification)
Any idea what can i do about this "schrödinger's brick" situation?
Or should I tell my friend that his tablet became an old-school calculator
Update:
I just realized that the recovery mode is fastboot (Sorry I'm unsure this is the proper name of it) and I was able to connect to it from terminal so most probably:
1. My friend did messed with the tablet...
2. I don't think it is the original recovery menu (or is it?)
3. Maybe I can flash some new rom on it!
Can you guys recommend something? I have no experience with fastboot at all.

Galaxy Tab Active 2. No odin / download mode.

Long story long.
Friend buys a load of tablets at auction, buried in there is an almost brand new (looking) sm-t395.
When turned on, it goes to a home screen with 2 buttons at the bottom, "Administrator" and "User".
Of course, these appear to passwords and of course, we have no idea what they are despite the scribblings all over the boxes.
No problem, says I confidently. We'll factory reset it.
So I boot it into factory reset mode and it does nothing, other than tell me that MDM will prevent factory reset.
Duckduck go explains MDM is like KNOX, a lock to stop devices being reset but it also reveals that it is possible to flash the stock firmware back into it and voila. Which is how you deal with googles FRP essentially.
OK, thinks I, this is sammys version of googles FRP so I think, ok, ODIN.
Now I have used ODIN about 4 times in 10 years or so, so I am not entirely familiar but I know that the android device has to be in download mode and HERE is where my master plan falls apart.
I **cannot** get this thing to boot into download mode. Recovery mode, not a problem but ODIN mode, nah having none of it.
So, would someone please tell me what and indeed IF I am doing something wrong. Tried vol+, home then power then release at same time which takes me straight into recovery mode, same but with vol- does the same.
Am I urinating into an oncoming breeze or can this thing be salvaged? He's promised it me for payment for fixing the others. Usual stuff, cracked screens, faulty usb ports, run of the mill stuff.
Thanks for any assistance.
