if you by this mean that you press the tip of your stylus into the hole in the left part of button of the xda once then yes
then try to turn it on using the turn on / off button
I tried, but it did not turn on, when I put it to cradle led is green, but when I get it out of cradle I do not see any light on led. I tried to power it on pushing that button, but nothing happens
is anybody able to help me?
If it neither works in the cradle or on battery power then I would suspect a component on the charging circuit has died or your battery is kaput, by doing a reset it should switch on automatically.
but holding power button and doing soft reset I could get to wallaby bootloader, so battery does work. any other suggestions?
If holding power and rest works then the power button is functional, have you attempted to flash the xda before this happened? What happens if you push the green telephone button bottom left of your xda? Have you tried a hard reset, using the unscrewed top half of stylus to push once in the tiny hole bottom right of xda, leave for 1 minute then push once more. You will lose all data but your data isnt much good if you cant switch on.
yes, I tried to hard reset it several times, but had no result. now I am trying to wait for several minutes during hard reset. when I press green button - nothing happens. I did not try to flash my XDA before those problems appeared. no it did not turn on even after 5 minutes... :-( please help!!!!
I had installed KSE TrueFax 2 and this power issue happened to me. Could not switch it on at the XDA at all, and had to so a soft-reset to get it to switch on. After I uninstalled the fax sowftware, everything worked okay again.
so you can power phone on pressing button and dping soft reset. yes? what do you see? wallaby bootloader? what to do next to run operational system? I just see 4 color stripes and below GSM OK, that is all, what should I press?
dmjass, it seems to me that you have lost or corrupted your rom, if you havent been flashing the xda its beyond me why this should happen. I would download a new rom, not radio stack, just the rom and use the sd card method of flashing, this should restore your system if the hardware is all ok, you have a working bootloader and an intact gsm stack so give it a try as you have nothing to lose by doing this.
I think trying to do the SD-card ROM update is your best bet as well.
If it turns out that you cannot get your unit running again, I would be interested in purchasing it for testing purposes and replacement parts.
Good luck!

thank you friends for your advices, but please let me know how to perform flashing rom by sd card. I will appreciate all your help, please describe that process in details. ok? thank you.
PDA bad ROM?
I am experiencing the same problem after having dropped it off my belt clip. Now the unit just says "Welcome to T---Mobile, G324e4 // R6.25.02 // 4.01.16 and none of the buttons work except for the boot stylus ones. Can anyone help?

Can't Remember Unlock Code

Hey,
I lent my phone to a friend a few months ago, and they put an unlock code on it and can't remember what it is. I know the gmail account and password, but every time I put the email address and password in it says invalid username/password.
Is there anyway I can do a factory reset of the phone. I tried holding down Home and Power On, but this happens http://c848462.r62.cf0.rackcdn.com/b4bdfe9625ba680f1724fb8e1f461772.png
I tired swapping the SIM for my friends (phone is carrier unlocked) which also has 3G data allowance, but it still wouldn't accept the email.
Thanks,
Charlie
I read somewhere that you can do the reset if you power the phone on while holding Home and Back. I'm not sure, though...

After pressing home and power you need to press power and volume up I'm not sure but I know it is something volume up or volume down try power first then you can wipe it from there

SCH-I915 demo unit

i purchased a tablet today a verizon galaxy tab 2 4g lte the model number on the back is sch-i915 but it seems to be a demo unit every 2-3 minutes it starts a video like you would see at the store and also whenever i delete the vzw demo showcase program it reinstalls it self and starts up again anyone have any idea how i can make this unit a regular tablet again thanks
anyone can help?
Have you done a factory reset in recovery?
I'd walk you through it but I no longer have a stock setup so I'm unable to give detailed instructions. I'm also not sure if the Galaxy Tab 2 is the same as the first generation (the SCH-i905 is somewhat supported in this section of the XDA forums, the SCH-i915 is the Galaxy Tab 2 version which is not and you should go here if you have that model: http://forum.xda-developers.com/forumdisplay.php?f=1596 ).
For the SCH-i905 what one does once the tablet is shut off is hold down the UP VOLUME button and then hold the POWER button. Immediately release the POWER button once the samsung logo appears on the screen and you'll be greeted by the bootloader menu allowing you to toggle from Download mode to recovery mode (open box with arrow pointing to android). A single press of UP VOLUME moves your selection to recovery and a single press of DOWN VOLUME acts as the enter key. You'll then be in recovery and somewhere within the stock recovery should be a factory reset option.
You will lose all of your files when you do this so be careful, back things up first.
If this doesn't work what I'd do is look into rooting the tablet, get it rooted and then use Titanium Backup from the Play Store to FREEZE the application.
I have that model now too. I haven't had that issue. I too would recommend a factory reset.

ANS UL40 from American Network Solutions (Assurance Wireless) Virgin Mobile

American Network Solutions (ANS) mobile phones provided by Assurance Wireless (Virgin Mobile) have been known to boot loop, freeze, stay frozen, crash, (right out of the box, brand new) and worse there is inaccurate or completely wrong information on how to do a factory reset and reboot the device. Below I will outline how to reboot the phone and perform a hard factory-reset with no home button on this cellphone.
Problem: Phone won’t turn off, won’t restart, or is stuck on and has no removable battery.
Solution: Keep the phone on and unplugged until battery dies or perform a hard reboot (see below).
Problem: My cell-phone is stuck on and there is no home button to do a hard reset
Solution: Perform a hard reboot. To restart a phone without taking out the battery, simply hold the Volume Up button, the home button (do not press if there is none obviously) and the Power button at the same time. While you hold these simultaneously, the phone will reboot in about 5 to 10 seconds.
Problem: I can’t factory reset my ANS UL40 phone (American Network Solutions) from Assurance Wireless by Virgin Mobile because I can’t get into the recovery menu.
Solution: Turn the phone off (or do a hard reset by holding the Volume-Up Button and the On-Button. Phones with no home button all reboot like this so just wait a few moments and the phone will restart.
Problem: My new mobile phone from Assurance Wireless gets stuck on the loading screen!
Solution: Perform a hard reboot (Volume Up + Power) then when it restarts and you’re on the white Assurance Wireless screen, stop holding power and only hold Volume Up. Keep pressing-and-holding the Increase Volume button and after a while you will be navigated to the Factory Reset Menu. You can wipe the cache partition only or perform a factory reset (which will also wipe the cache). To move around on the menu, use the volume keys (increase volume goes up, decrease volume goes down) and to select your entry simply use the power button (the on button). If this still doesn’t work, see further instructions in the solutions below.
Problem: Phone is frozen on loading screen, stuck in boot-loop even after factory reset/wiping cache partition.
Solution: After you have factory reset or wiped the cache partition you can also choose to install an update from the internal memory or sd-card. If you select this option it will perform a more rigorous factory reset then since you won’t have a package to install it will cancel. I’ve noticed my device getting out of the boot loop once I did this process and it was stuck on the boot screen even after I did a factory reset.
Problem: Can’t get to the recovery menu with my government assistance phone.
Solution: Turn off the phone and with the volume up button held down, power the device on. Keep holding both buttons until you see the white “American Network Solutions” screen with the outline of an eagle. At this point release the power button and continue to hold the volume-up key. After about 5 seconds you will now be inside the Recovery Menu and can do a factory reset.
Problem: My phone has no home button and I need to hard reboot to get to the Recovery Menu and perform a factory reset!
Solution: Hold the Volume-Up Button and the Power Button at the same time. for at least 10 seconds. Your device will restart and after the white ANS screen shows, stop holding the power button. Continue holding the increase audio key until you are at the Factory Reset / Recovery Menu screen. Use the volume buttons to navigate the menu and use the on button to select your choice.
Problem: My phone hangs on the blue Assurance Wireless screen.
Solution: See Above.
Even on the Virgin Mobile and Assurance Wireless websites and in the owner’s manual it says to hold the Volume Up + Home Button + Power Key and to keep holding them until you’re in Recovery Menu. This isn’t going to work for two reasons on the UL40: 1) It has no home button! and 2) it will just keep rebooting every 5 seconds if you hold the power button down constantly. You have to hold the Volume-Up Button and the Power Button until the phone reboots and then let go of the power button while still holding the volume up button. Keep holding the volume up key until you’re into Recovery Mode.
I hope this helps as the information online is either incomplete or completely wrong. Some places say to keep holding the power button along with the volume up key and if you do that the device will just keep restarting, effectively creating a boot loop where there wasn’t any before. Genius! lol. I figured this out after my device, fresh out of the box, froze while charging on the blue Assurance Wireless screen. Finally OCD is good for something! These phones are supposed to be a “Lifeline” but I’d be hard-pressed to get ANYTHING on the line with this potato. Avoid at all costs unless absolutely necessary.
Enjoy.

Is it possible to swap my UL40 for a normal phone I can use JUST to make necessary calls to relatives or EMS folks for help if I need it? This Obama phone is far to smart for me.
You have to call ASSURANCE; or go online to your ASSURANCE account and try to SWAP phones. Good luck.
Note: The UL40 is pure JUNK. DOJ is looking into multiple fraud claims.

Cell phones are like min-computers. For instance, if you don't like ads on the internet you have to use an ad blocker. It is the same with cell phones. Apparently before smart phones the Assurance Wireless phones were not as much lie computers and did not have ads, but now they do.
Does anyone know of a way to bypass the lock screen?
My father died suddenly with the phone in his pocket. Looking to get pictures off of it as well as investigate any communications leading up to this death.
Willing to do anything to prove this is legitimate. Sign a document, show my identity, even pay someone to unlock it, etc.
And to those "give the phone back to its rightful owner" people in advance - my father's body was not discovered until ~3-4 days after his death, so it was partially decomposed. I can send pictures of the UL40 phone soaked in the bloody ooze from his decomposing skin if you're interested. Took hours of cleaning to make the stench of death go away :victory:

How to get into recovery mode for S7+? Nothing worked for me!

I tried the usual key holding combinations but they didn't work. I even tried connecting headphones as suggested on reddit, but that didn't work. I'd like to wipe the cache partition and troubleshoot a font issue.
My S7+ tab is NOT rooted. Thanks
You need to plug it into a computer via USB for it to work.

Thank you. Can you confirm what the correct procedure with Android 13 is once plugged in? Thanks
Android 13? Don't you mean 12?
Samsung hasn't released Android 13 for the Tab S7/S7+ yet.
My bad. Yes, I mean 12. I noticed the fonts are now small, even after doing a factory install.
For instance, when using Google Sheets app and selecting a file from the device, the name, size, etc. fonts are all tiny now. Has anyone else noticed this?
BTW, I wasted hours and I lost some data because I couldn't do a clean reset as I wasn't able to get into Recovery Mode with S7 tablet connected to my PC.
I'm sorry to hear that. Being connected to a computer via USB and holding the power and volume up buttons, then releasing as soon as the Samsung splash screen appears is the only way to get into recovery mode.
Hey, I don't know if you still need to know how to factory reset your tablet from recovery mode, but I had the same problem and I've followed this quick guide and it worked for me
1) Press the "Power" and "Volume down" buttons simultaneously until "Switch off" and "Restart" appear on the screen.
2) Press the red "Switch off" symbol on the screen and confirm again. The tablet shuts down.
3) Connect the tablet to a PC with a USB-C cable and wait until the final battery level is displayed in percent (the percentages count up and the circular ring around the battery level becomes brighter and brighter). No "recovery mode" without USB-C cable!
4) With the tablet still switched off and connected to USB-C, press the "Power" and "Volume up" buttons until the tablet has entered "Recovery mode".
5) In "Recovery Mode", the menu items can be selected with the "Volume up" and "Volume down" buttons and confirmed with the "Power" button.
6) Exit the "Recovery Mode":
Remove the USB-C cable.
For some reason it only worked after I installed Smart Switch...
has samsung acknowledged this new procedure?
is it documented by samsung?
I spent 45 minutes chatting with Samsung support yesterday and one of the things they asked me to do is clear the cache from the recovery menu. I tried many many times using just the pwr/v^ buttons and they kept repeating the same instructions, then told me that I must have a faulty device. Eventually I quit the chat and came to look here and I can confirm 100% that when connected via USB to my pc the pwr+v^ method works.
I think the, plugging it in to a PC via USB requirement was implemented when it was updated from Android 10 to 11.

I downloaded the latest version of the user manual (Apr 2022) and it was not documented.
I don't remember where I first saw the change. But it has been over a year; I think when Samsung updated it to Android 11.
