[Q] SGH-M919 - Black screen after entering encryption key - T-Mobile Samsung Galaxy S 4

Re-typing this entire question because the forum ate it before posting it.
SGH-M919 (NOT T-Mobile, but a carrier called GCI.)
Contract was bought-out by another carrier so I could get an iPhone. Trying to get the Galaxy reset to factory condition so it's re-usable.
Galaxy was encrypted to comply with work email requirements. I needed to reset the phone quickly and couldn't find the factory reset menu option so I gave it the Volume Up + Power salute. I chose to erase user data / factory reset. I later read that this method may cause issues if the phone isn't DEcrypted first.
When the phone boots up it wants the encryption key. (I wanted the user partition WIPED, not just emptied.) If I intentionally give it the wrong key it keeps asking for one. If I enter the correct key it briefly shows the outline of the green Android logo then the screen goes black. Phone is not dead because my Mac recognizes it as a network interface when the phone screen is blank. The menu and back keys don't respond or illuminate, however, if I reboot the phone, enter the encryption key and then repeatedly tap the menu button until the green Android image disappears the buttons will stay illuminated.
I don't care about what was on the phone. I wanted it to be as if I had just turned it on for the first time.
Should I try having the carrier, who no longer services the phone, try to re-flash it? I've tried making heads or tails of how to flash it myself but the fact that it's locked to a tiny carrier it's next to impossible to find any helpful info. Any suggestions would be appreciated.

how to unlock htc touch without password

Friends,
I've just joined the forum. My HTC touch has just been locked itself and I can't unlock it because I didn't set a password. I still can receive calls but can't make calls, the screen is password screen, nothing else. I can't shut it down without removing the battery.
I tried PIN, PUK, IMEI, 0000, 1234, etc but didn't work. I tried soft reset but didn't help. Tried hard reset but it didn't reset. I tried the SIM card in other phones, it works, thus, the problem is the device.
Any help will be appreciated...

You want to double check about that hard reset. I think you've probably only done a soft reset. A hard reset will reset the machine back and wipe off ALL your data and settings, including the password.
The front screen password of which you are referring to NOT any of the ones you have listed, but instead it is something you would have set when setting up the device.
Have a try with some of your usual passwords
I have tried hard reset (pushing green and red buttons at the same time pushing the reset button with its own pen) but, didn't reset (since there appeared no message on the screen like "the data will be lost"). I think those two buttons are not functional because of password. Every time I tried hard reset it has done the soft one.
thanks anyway

I'd suggest you query this in the HTC Touch forum rather than the General Forum for everything, as they have more intimate knowledge to help you
Hi there, my HTC touch just did the same today. I never set a password.
I contacted my IT guy and he mentioned the following:
Try number 1 once, and then tap unlock.
WORKED BRILLIANTLY!!
The HTC Touch does that all the time.
All you need to do is hold down the Send and End Call buttons down firmly and push the stylus up in the little hole near the usb port (Reset Button) and wait till the screen says that the phone is going to format and all data will be lost press the soft key to continue. Then when it says that press the center button and it will show Fat formatting and Rom formatting. This will erase all data on your touch so make sure you back up.
After turn on the phone and go through the set up and it should be perfectly ok.
You can do this for two reasons.
1. To reset the phone locks.
2. To repair the touch screen if it stops working.
Hope this helps. Enjoy
Dotybizz, I guess the O/P wanted a way to recover without wiping his data. However, due to the security reasons I'm sure you know about often that isn't a suitable option.
Not working

A Hard Reset restores the device to its default settings - the way it was when you first purchased it and turned it on. Any programs you installed, data you entered, and settings you customized on the device will be lost. Only Windows Mobile software and other pre-installed programs will remain.
There are 2 ways to perform a Hard Reset on this device:
Menu path
* 1. From the Today Screen, go to Start>Settings.Select the System Tab and then tap on Clear Storage.
* 2. Enter in the password provided on the display of the device (should be 1234) and tap Yes.
* 3. The device will begin the Master Reset Process.
Keystroke Method
* 1. Power the device off.
* 2. Press and hold the Volume Down and Center Navigation Button at same time, do not release.
* 3. Press Power button and hold for a 3 count (quickly - say one thousand one, one thousand two, one thousand three). 1-2 seconds is too short, 4-5 seconds is too long.
* 4. The screen will instantly show the text to hard reset (this is a white screen with Blue text that provides the next steps to complete the Hard Reset. If you do not get this screen, power the device off and try again).
* o Warning! Your device will be set back to factory default settings. Please ensure any additional installed programs and/or user data is backed up before proceeding.

Hard reset not working

After having thoroughly read the 280 pages of the UM of my Rhodium, I've tried several times (three digits number !) to hard-reset my machine, but alas, without success.
I've tried every possible combination of ON/START/STOP buttons but none works.
I either happen to make the message "do you want to switch off your mobile" (in french, as French am I) or the menu to activate ringer/vibrator etc to appear, but never ever got the ability to hard-reset my unit.
What's wrong with me/my Rhodium ?
Thx in advance mates !
Instructions on how to hard reset are in the wiki. Don't know what these "ON/START/STOP" buttons you mentioned are. The buttons involved in making a hard reset are the Power, Call Send, and Call End keys.
Alternatively, you can go to "Clear Storage" in your settings and follow the directions on screen.

You do know that you need to turn off the device first? Alternatively, do a "clear storage" as mentioned above, if you still have access to your device.

Yes, I do know, thank you for your response, and I tried either way unsuccessfully !
I do have access to my machine but needed it to be fully reset.
"clear storage" works fine, but that does not explain me why the "three finger salute" fails...
You are keeping the SEND and END keys down whilst you turn the POWER on aren't you? then releasing only when you see the tricolour screen
I updated the wiki page the other day to make the steps a bit clearer.
Give it antoher go .

Problems with Hard Reset on a Verizon Touch Pro 2
Hi Guys,
I've had my Verizon version of the phone since the beggining of the week and I cannot make a Hard Reset work either. The combination of Send/End/Power buttons do not work, and on my Verizon version there is no "Clear Storage" item under the system tab in settings. I've watched the U-Tube clip in the Wiki, and I note that HTC's site for the Verizon variant refers to using "Clear Storage".
Looking in the Windows directory there is a Clear Storage html file but there is no ClearStorage.exe. I have extracted a ClearStorage.exe from my Tilt and inserted it into the Windows directory of the Touch but to no avail.
Does anybody have a fix for this? Could this be another "exclusion" by Verizon to stop us working with our phones?
Sorry to insist, but you have turned the device completely OFF, right? So it's not just in "stand by/screen off" power saving mode, but completely off? So that when you press the power button, the phone starts loading WM etc.
Again, sorry to insist, but I couldn't figure out any other reason for the hard reset not to work.
Don't mind you insisting because this issue is stupid. Yes I have turned the phone completely off by pressing the End button until the phone states "Your phone will be turned off. Press No to cancel.
When I attempt the Hard reset it the phone merely restarts regardless of how long I press the buttons.
All this would not be so much of an issue if "Clear Storage" was available. Short of waiting for the first cooked ROM (and therefore Hard SPL) to appear for the CDMA phones, is there any way to put that back? Obviously it requires more than copying the .exe to the windows directory. My Tilt has a 6.5 cooked ROM. Is is possible that the .exe is slightly changed in that one vs 6.1?
Other Verizon phone owners - can you confirm that the "Clear Storage" is missing?
Edited:
On my Verizon, the Clear Storage is on the System tab, under 'Memory'. Select 'Memory' and select the Clear Storage sub tab.
Taken from ppcgeeks:
FOR VERIZON TP2 ONLY (Sprint & GSM have different settings)
Soft reset
Hold down the end key till the device powers off, then hit the end key to start your phone. You can also hit the reset button under the battery cover.
Hard reset
Hold down the end key till the device powers off, then hold volume down, send and end till you see blue text. Follow hard reset prompts.
Security
Hold down the end key till the device powers off, hold vol down and end to get to security(rainbow screen).

I just confirmed that this works on a Verizon phone. I got the hard reset prompt with this key sequence.
For Verizon users that want to do the clear storage through the OS, it's located under Memory in Settings on the Clear Storage Tab.
Settings -> All Settings -> Memory -> Clear Storage
Happy formatting :-D
Thanks everyone
Thanks everyone for resolving this.
This is what HTC Touch Pro2 (Verizon) site says under FAQ "General & Others":
"Q. What does a Hard Reset do and how is it performed?
A hard reset removes all information from your device and returns it to a state just like it has never been used before. All contacts, messages, emails, 3rd party applications, etc. will need to be reinstalled after performing a hard reset. To perform a hard reset, navigate to Start > Settings > All Settings > System (tab) > Clear Storage. Follow the on-screen prompts to complete. This process will take 5-10 minutes".
Clearly no reference to being under the Memory Icon. The link is:
http://www.htc.com/us/faqs.aspx?p_id=294&cat=90&id=110490&f=t
Could we ask the moderator to arrange for the Wiki to be updated for the CDMA vcersions?
I have a Verizon TP2. Clear Storage on my phone is located at Settings/Memory and then the Clear Storage Tab. It asks you to enter a number to reset your phone and restore Verizon default settings.
Edit: Bah, guess I didnt see the second page )

HARD reset - changing phone

I've been trying to find the right information but struggling. I am having my Desire exchanged for a new one as mine has a minor fault. T-mobile have been great in getting this exchanged.
My issue is that I want to be able to store all my information somewhere first and I think I know how to do that on to the SD card.
My more important issue is to be able to delete all the information from the phone after my backup so things like my facebook details, gmail and everything else is deleted. Will a HARD reset do this and how do I do that? Is there a different way to perform a full reset to ensure everything is gone?
|Thanks...
Factory restore/hard reset, and then you'll need to format the SD card (or remove everything on it)
Turning automatic backup on:
1. From the Home screen, press MENU, and then tap Settings.
2. Scroll down the screen, and then tap Privacy > Back up my data & settings.
3. Select or clear the Back up my data & settings check box to turn automatic backup on or off.
After you do a factory reset, your phone will restart and let you restore the saved data and settings in your storage card back to your phone.
Your phone backs up the following types of data and settings whenever there are new additions or changes:
* Text and multimedia messages
* Settings in the Messages application
* Web bookmarks
* Keyboard dictionary
* Settings in your phone that fall under these categories:
o Wireless & networks
o Sound & display
o Location
o Applications
o Date & time
o Language & keyboard - only the Locale setting
Performing a factory reset (hard reset):
This returns your phone to the state it was in before the first time you turned it on (factory settings).
Note: Factory reset will not remove the data and files that are in your phone’s microSD card.
This will permanently delete all your data and customized settings, and will also remove any applications you've downloaded and installed. Be sure to back up any data and files you want to keep before you do a factory reset.
Performing a factory reset via settings:
The most convenient way to do a factory reset is via the phone settings.
1. From the Home screen, press MENU and then tap Settings.
2. Scroll down the screen and then tap Privacy > Factory data reset.
3. On the Factory data reset screen, tap Reset phone, and then tap Erase everything.
Performing a factory reset using phone buttons:
If you cannot turn on your phone or access the phone settings, you can still perform a factory reset by using the buttons on the phone.
1. With the phone turned off, press and hold the VOLUME DOWN button, and then briefly press the POWER button.
2. Wait for the screen with the three Android images to appear, and then release the VOLUME DOWN button..
3. Press VOLUME DOWN to select CLEAR STORAGE, and then press POWER.
4. Press VOLUME UP to start the factory reset.

Thanks
I rang them up to say the battery life was absolutely dreadful. They said give it a few days to see if building up the charge for a few days combined with the "new phone and let's play with all the new features" syndrome settled the battery life. It hasn't and they suggested either sending a second battery or exchanging the phone. I went for the exchange....
Apart from that, the phone has been absolutely brilliant. Really pleased with almost everything. My only two hmmm's have been that skype don't do their own app for Android and that the F1 app for the iphone isn't available on android (despite its $29 cost!!!)
Thanks. I'll be real interested to learn if the exchange phone improves your bettery life - be sure to let us know!
I bought a HTC desire from Virgin mobile uk which uses t-mobiles network. I had problems with the browser force closing where it started and then quit. I spoke to HTC and then was advised to perform a hard reset using recovery mode. I put the phone in recovery and then immediately got a phone picture with the exclamation mark... i had to remove the battery and tried it again. same problem.
I have found that the second phone i had did exactly the same when i tried to put it in recovery mode..ouch
I'm going to do the backup first so I hope I'll have the info saved..... that's a weird problem you have.
I will let you know how I get on with the replacement but it will have to be when I get back from OZ......
I was hoping to find a pay as you go sim card to put in but my phone is locked to tMobile and also it seems in Australia their data plans are just not there yet...

Factory Hard Reset Not Proceeding (Fixing from a bootloop, data partition need wipe)

Hey guys, I'm using a stock L-01E (Just a JPN E975), when it heated up one day. Tried to turn it back on, but would only bootloop. Saw the guide here for bootloops (https://forum.xda-developers.com/showthread.php?t=2010624), and got until step 7. Now with a bootloop still occuring, I went and used the hardware buttons to go to the factory hard reset. Got in, selected to continue, but after confirming, it has been stuck on that screen for hours. All other videos I've seen had the device turning its screen off seconds after confirming. Can anyone help me? I really am in great need.
That's old method use this it's better.

Thanks. So going with CSE, the tool gets up to 98%, and the phone restarts, as it should. Problem is, the phone keeps bootlooping, and the tool says that the upgrade stopped due to an error. I checked the link you sent, and some people had the same issue, but no solutions were given. I'm not quite sure what to do with this now.
Master reset with hardware keys
A master reset restores the original factory settings and may delete your personal data on the internal storage, such as downloads, ringtones, images, apps, contacts, and Visual Voicemail. It does not delete data stored on the SIM card or SD card.
If the device menus are frozen or unresponsive, you can master reset using hardware keys.
Back up data on the internal memory.
Power off the device and ensure it is not connected to any USB cables.
At the same time, press and hold the following keys for 8 seconds:
Power key
Volume down key
When the LG Logo is displayed, release the Power key and then immediately re-hold the Power key.
When the 'Factory data reset' screen displays, release the both keys.
Use the volume keys to select yes, use the power key to confirm.
Re-confirm by using the volume keys to select and power key to confirm.

Question Realme C21-Y RMX3263: hard reset - factory reset with black screen / no button

Hello,
sorry to write here, I cant find the C21-Y section.
Direct question: is there a way to perform a factory reset not having the possibility to do it using the combination VOLD DOWN + POWER BUTTON and NOR using the standard Android UI?
Note, not activated debug mode
For more details see here below
I recently did a factory reset in "normal way", I mean using the standard Android user interface through normal menu.
Then, I changed only 3 things (without considering the minimum settings required at the first boot): show battery percentage, start black user interface menu and then after selecting the high contrast display... the display became black.
The display is responsive, because the phone vibrates if I touch in the position of the 3 buttons (back, multi, back).
Then, waking up the phone I can see the black smoothing on the display (hoping to make myself clear...) and I'm able - fortunately - to switch OFF the phone (basically touching the display in the right position and swiping to back, after holding a little the phisical on-off button).
Then, the display is working in the boot sequence (I can see the Android logo and the Realme animation): it stops once the Android system is loaded.
So, I tried booting the phone with the combination VOL DOWN + POWER BUTTON but it doesn't work... It seems an issue that afflict some pieces of this phone (read in some post, video I searched before writing here)
Well, how I can in this situation perform a factory reset?

You should be able to boot in to recovery mode where the device is powered off state and when you use key combinations to do
Keep holding the keys even if you see splash screen, untill recovery screen appears
You can also try holding volume key and connecting to computer via USB cable, without needing power button.
Unfortunately with this phone (or the Android version installed in the one I have) have some issues and... butroon combinations are not working
I think I've tried in every way, different combinations. No luck
Both (button combination and black screen) seems to be "common" (search on youtube black screen C21-Y) and the only way is to flash it and/or force the factory from PC (I don't have at the moment understood if for thios phone the only factory from PC is working)
Being a sw issue I'm trying to intercept Realme support, before trying any flash or something similar... but after the first answer to my mail they didn't come back again
I just call Realme support for a similar issue on C21-Y. They tell me this model doesn't have a recovery installed and olny way is to send back to factory and they will provide a factory reset.
What a bad product, no words.
Follow this, it worked in my case (without flashing the phone)
