[Q] Chinese tablet hangs after being fully booted, anyway to hard reset? - Android Q&A, Help & Troubleshooting

I've got a Chinese tablet that boots properly up to the unlock screen, where if I'm quick I can unlock, I can see wifi is connected, etc. but around that point it completely freeze, even the power button doesn't turn off the creen and I have to reset it by long pressing the power button.
I tried all combinations of keys to bring up a recovery (power + volumes) without luck so far. If I press any volume or back key while powering up, the tablet doesn't power up and stays black. adb isn't finding the tablet. I opened the tablet, there are pins to connect a rx/tx serial. I could do connect a serial adapter to it if that could be of any help.
Actually, at this point I don't care much about the tablet but that could be a good opportunity to start learning a bit more about Android hardware development, just don't know exactly where to start.
Any tip?

[Q] Stuck in APX mode - I believe?

Hi everyone
I'm desperate.
My TF201 (stock - not rooted - and successfully updated to the current version) works flawlessly for the first 3 months and then one day the Volume UP key stop working. Whenever I tried to lower the volume, it will automatically up it again. When this happened, I tried to reboot with the power button but the tablet wouldn't respond. So I pressed the power button a bit longer and it will shut down. But, when I tried to power it again, I will feel the buzz but the screen will remain blank. The first few times that this happened, I used a small pin to reset the tablet and it will reboot normally. However, now this procedure also has stopped working and I cannot get the tablet to boot again. When I plugged it into my PC, it will recognize it as an APX device. I found that if I let the battery drain completely, it will then power up. I have read and tried the different methods mentioned in the forum but to no avail. So after reading sledgie's post in one of the thread, I thought that perhaps the Volume UP key is definitely stuck and that's why it's booting in the APX mode every time. So, I bite the bullet and open the tablet to see if I can fiddle with the volume keys. But alas, even after making sure that the volume key is not getting stuck, the nightmare continues and every time to boot the tablet I have to let the battery drained completely. What I could gather though is that it's definitely the Volume UP key because every time if I could get the tablet to boot, after draining the battery completely of course, when the ICS Home screen will appear the volume icon also will appear by itself. I found that so long as I don't the touch the Volume key, the tablet will work flawlessly and I could press the power button to get it to sleep and to wake normally. But if I touch the Volume key then the power button will not respond.
So, as I said I'm desperate and if anybody has a solution, please advise.
Thanks in advance.
Help!
Anyone?
i think you should exchange it or send it back for RMA. Make sure you contact Gary Key with regards to APX state. I wrote in the other thread without seeing this thread, but this is what it sounds like.

Another kind of situation that nvflash would be useful.
Sent from my i9250
agreed.
Sorry to respond very late but I want to know what this 'nvflash' means and how will it be useful in my situation. Should I 'nvflash' my tablet in the circumstances?
It's not possible yet, unfortunately. Asus retains the locked bootloader key. We have a way to flash it (SBK I believe) but without the unlocked bootloader, we are not able to proceed further. This is unfortunate for both sides - customer and Manufacturer

I havea Hipstreet Titan HS-7TB4-4BNDL with WiFi 7" Touchscreen Tablet PC
I uninstall/installed some apps from the tablet like (app installer,Sitting,System UI ,Packet installer,Etc) and the next Boot when I turned it on, it quitted booting and the screen froze with the HIP-STREET still in the center of the screen than going blank.
I had tried a lot of ways to make it boot again including hard power off (pressing the power button for more than 5 seconds), reset the device (pushing a small pin to the small hole at the side of the screen, there are 2 holes: one for microphone and the other for reset button,try to press combinations of various keys I can find on the tablet pc. They all failed to fix this
Can Somebody help me or guide me to bring back my hipstreet tablet back to the original state.

[Q] Xperia Tablet S (SGPT1211) not responding to reset/boot comands

Hello,
I think I might be at the end of the road with my tablet. I've never rooted it or tampered with it in an way, however yesterday it locked up so I did the usual soft reset (hold power and vol+ for 10 seconds) I then turned it back on and the sony logo popped up, but there it just hung. If I press and hold the power button it switches off, a brief press on the power button brings it back on in the same state. So I go Googling, including looking at threads on this site, all seemed to advise to try to get the Android recovery menu up. on the Sony this is done by holding the power and vol+ and then releasing the power button (only) when the son logo appears (this process to be started when the tablet is off) so I did this, and no response at all. Worse than that, where it would turn on and instantly hang, it now doesn't turn on at all. Hooking it up to my PC I can see the device in device manager, but it tells me my usb device has malfunctioned.
At the moment, my thoughts are to open it up, to:
1. Check that the power/volume buttons aren't stuck in some way (preventing the boot command being given correctly)
2. Remove and resolder if necessary internal battery to force a power cycle.
3. Bin it and get something new (it is 2.5yrs old so no big loss i suppose)
Any ideas where to look or similar experiences?
Thanks

Reset the Phone
You need to do a factory reset. Hold volume 'up' button and power button at same time for a minute or so, then choose factory reset.

The battery is taped into the case with double-sided tape - in other words, very gently pry the battery out (from bottom of battery) & leave it out for a minute or two. Then put it back in & try again.
Fixes for the Boot Loop/Frozen ANS UL40
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. :highfive:

Great advice. Have had an ANS UL-40 for over a year, & they truly stink if you can't root them - which I can't since I've no computer access (for ADB). I honestly miss the old android Jellybean phones that could be rooted with just an app. Oh well.
I have a UL40, I tried the factory reset method, it reset but the phone is still suck on the blue assurance wireless screen.
Ps. It's been like this for days. It stays on the blue screen for about 5 minutes, then the screen is completely black. When I try to turn it on again, it's blue for five minutes then goes black.
Help...?
My ans ul40 keeps restarting. Every 2 to 5 seconds, on its own. I tried to factory reset it with the steps listed above and I can't tell if it works because when I hold the volume up and power button, it does two things, the phone will either shut off again and go into the constant restarting or number 2, it will show me a white screen as if to say the holding down of the volume and power button worked, but then it just goes back into the constant restarting... at this point I'm thinking I have to call for a new phone.
I have a ul40, technically 2 because one wouldn't hold a charge and now this one keeps crashing and giving me error codes. I can't afford to just drop money on a new phone (hence why i got this one) and I am FORCED to do a factory reset every 3-5 days because the memory gets so full, even if I erase memory, disable or delete apps and barely use it outside of texting or calling. Its frustrating to high hell. The code that shows up is either "GOOGLE SERVICES FRAME WORK KEEPS STOPPING", or "COM.ANDROID.PHONE HAS STOPPED"
Any advice is helpful advice.

i have a similar problem except it gets to the blue assurance screen and then it turns off and then reboots i can't fix it and i don't know what's wrong this is the only phone i have (don't laugh) but i can't not have this phone
Have you tried taking out the battery for a minute or two, then powering up? (Battery is only held down with tape - it can gently be pried out). The other option is a complete reset - instructions on holding the power & volume keys, etc, are posted already.
this phone seems to ship with a lot of malware factory-installed (and possibly more built into the firmware?) so it's critical to go into Settings->Apps and disable everything that looks suspicious, including the less obvious "notepad" app and "voice recorder" app. this should help your phone run somewhat better but there's some adware still running that i haven't figured out how to disable, so a perfect solution in theory would be to root the phone as discussed in this thread. unfortunately so far there doesn't seem to be a working root for this phone.
I did fatory reset from recovery until arrivet to let us go then skip sim then next as new device/retrive from cloud then lis of wifi appear and stop at this point nothing else appear to enter
what the solution please?????

HELP

Samsung Galaxy S9+ No custom, Just a normal phone from T carrier.
The situation is as follow. I wake up everyday and cannot turn on my phone, the screen is black but I hear it beeping when i press the volume keys. I do a Vol down Power to restart thinking it will , it restarts but the screen is black and unresponsive no matter what I do, the Power button is still functional at this moment.
What I quickly did is I connected the phone to my monitor using USB-C and i have a mouse connected to the internal KVM of the monitor- , perfect got excited that the phone at least works, on the monitor it shows up perfectly, I can control the phone with the mouse, enter my 4 digit password, works. That was the situation yesterday. Should have backed up then but didnt.
Today I wake up, the Power button does not work, so I read and find out that I can go downlead mode which I did using the Vol down and Bixby and plugging the charger.
tried the Vol Down and Power to restart it does not, so again I go in to the download mode and accidently press Volume up, Now I am completely stuck on Downloading... Do not turn off target
1. Power button does not work- I have no idea how to get the past Downloading screen now
2. Would I be able to recover anything it its really dead?
3. Any tips?
