Denver TAC-70061 Tablet stuck - Android Q&A, Help & Troubleshooting

I've looked through similar thread on how to boot into recovery menu, but non of them work for this lame Denver p1ece of sh17 product. The tablet loads only to the 3rd page, and never gets passed it. I've ben trying to set it back to the factory default, but whenever I hold the volume down button and power button, the sh17 takes me to a screen with the robot laying down and exclamation mark inside of a triangle over top of it. I don't end of seeing anything else, like there is not list of options to choose from. Although I got this p13ce of hardware for free, any1 know how to reset a Denver specific type tablet back to the factory default settings right quick? If so, how do I do it before a slam it on the floor?

Recovery mode of Denver tablets
DENVER ELECTRONICS A/S explains to access the recovery mode (e-mail) – maybe this helps you:
You can factory reset the tablet the following way:
Plug in the adapter. Press the reset button on the back of the tablet and wait for approx. 20 seconds (until the battery icon disappears and the screen goes black).
Press the power button for 5 seconds.
When the Denver logo appears, press the power button 2 times (short fast press). (If the tablet powers of for start with “Android” – start again at step 1.)
Wait until you enter the recovery menu. Press the power button 3 times (don’t hold the button, short fast press).
“4. Wipe data/factory reset” must be marked.
Press and hold the power button for approx. 3 seconds, then release.
Use short fast presses to get the cursor to “8. Yes – delete all user data”.
Press and hold the power button for approx. 3 seconds, then release.
“1. reboot system now” must be marked.
Press and hold the power button for approx. 3 seconds, then release.

[Q] Factory reset

Hey Everyone
Im stuck...
I broke the LCd in my streak (for a second time). And am selling the unit for nearly nothing to a craigslist buyer...
Since the lcd is broken, i cannot get through the menus to do a factory reset...
Can someone give me the step by step to boot and do a factory reset.
I hold both volume up and down, power it up and release the keys. then i need to press either volume up or down to get to the factory reset then press the camera button. I just can't figure out how many times to press each button.
Anyone??
Thanks so much!
Just did a quick check, it's the first option of four so press your v+v- and power, then just press the camera button, should do it for you.
For my case, once holding down volup + voldown and the power button, the recovery screen will appear with the following:
1. Factory Reset
2. Update from update.pkg (Highlighted)
3. Screen calibration
4. Power off
Option 2 was the default highlighted (or selected whichever you want to call it) option.
So i need to press the volup button once to move the selection up to option 1 and then press the camera button.
Am using Simple Streak rom if that makes a difference in the screen display options.

question about bootloops???

i haven't experienced this but in case it happens, what if the phone enters a bootloop, how does someone go about turning the phone off (since you cant battery pull) and get into the bootloader/recovery??
hold power key for about 10 seconds or so.don't let go until phone turns off.
EDIT: Here you go Page 24. It says Note: If the phone hangs and the touchscreen does not respond, press and hold "power" for about 10 seconds to restart the phone.
EDIT 2: Also found this here
Symptom #2:
If the device cannot power on, and seems that it cannot be charged, it could be that the device is not in default operation mode. This can be caused when the “volume up key” was pressed while pressing the “power” key when device was last powered down. To power on and off the device normally, please be careful to not hold down any other hardware key while pressing the power key during power up operations.
How to fix:
1. Press & hold the power button for up to ~ 20 seconds. The capacitive keys (three keys at bottom of screen) should begin flashing. This indicates that a reset is imminent. Continue to hold power until they stop flashing.
2. Release the power key
3. Press the power key again for 1 second. Wait a few seconds and the device should then power on

Yeah I don't think that actually helps with a true bootloop. Restarting the device is just looping another boot. lol.
Try just holding down the vol-down button through one of the bootloops. Not sure that will work ... but worth a try.

Don't know which tablet i own (images)

Update - While holding power button and volume up then letting go of volume up after
2 or 3 seconds while both screen black or on first boot screen for a nano second I
get a standing up android with blue atoms going around it's stomach. then goes
onto the lying down android with red triangle. Will I need to insert an sd card with some
kind of software downloaded on it for this whole format to work?
Here's all the problems. Woke up in morning and tablet chose to be stuck on 'android' animated(shine effect going across 'Android')
boot screen. I have made no modifications to the files etc, just stopped working.
To help you maybe know what tablet i got here are the two boot screens:
(Well i would post images if the forum didn't have silly restrictions on it)
#1
s9.postimage.org/7e6ws3f73/CIMG3093.jpg
#2
s8.postimage.org/4xsov8n8l/CIMG3094.jpg
Anyway looked all over the net and the seen power button & volume key and it doesn't work. Here's what I get and what i tried.
#1 (tried both volume key plus and minus button)
Hold volume and power button until first screen
appears then next let go of power button but still holding
volume key just goes and get stuck at 'android logo' screen.
(I have also carried on holding power button through to second load screen too.
But! Holding down power button and volume up button until 1st screen with tiny
little android in circle then releasing power button takes me to the green android lying down
with red triangle
#2 (tried both volume key plus and minus button)
Hold power button until first screen appears
then next hold volume key and still holding
volume key but release power button just goes and get stuck at 'android logo' screen.
(I have also carried on holding power button through to second load screen too.)
Basically to cut it short I have looked via google search and come across plenty of forums
and tried to access the screen which lets me format the device but so far has become uncessesful
I hope the images help you know which device I have and also the photo of the tablet it's self to help you know
(it has no buttons on it except the power and volume key and has no small(tiny) or big reset button to press
from what I can tell.
(Again i would post an image here too if it didn't have silly restrictions)

Venue 7840 turns itself off while having half the battery percentage

Hi, I couldn't find anything about this issue here, on Dell forum there was discussion about it 2 years ago but it wasn't solved, but it seems that a lot of people face this issue and I'm honestly surprised no one talked about it here.
So I just bought this tablet, it's used but whatever, at 56% of the battery it shutdowns and there is no way to power it back on without connecting to the charger. Can't even access bootloader menu, it's just dead.
Has someone faced this issue and has any idea how to prevent this from happening? It renders the tablet unusable and I don't really want to pay the service for changing the battery if it's gonna do the same thing
Thanks
I got the same problem but no solution. The only thing I recognized, is that the tablet things it got 11.000 mAh instead of 5900 mAh. But why?

Found something:
Try the following and see if this resolves the problem. This is not a master reset so your information will not be deleted.
1. If your device is on, turn it off.
2. Press & hold the Volume down button. While holding Volume down, press & hold the Power button until the device turns on. You'll see the word "Start" with an arrow around it .
3. Press the Volume down button until you highlight "Recovery mode."
4. Press the Power button to start recovery mode. You'll see an image of an Android robot with a red exclamation mark.
5. Press & hold the Power button. While holding Power, press the Volume up button once. Then release Power.
6. Press the Volume down button until you highlight "Wipe cache partition," and then press the Power button to select it.
7. Press the Volume down button until you highlight “Yes,” and then press the Power button to select it.
8. Wait until the cache is wiped. You’ll see the words, “Cache wipe complete.”
9. Press the Power button to restart your device.

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?????
