Hello Community,
I got my Hisense A5 as a second hand device – possibly from chinahandys. It had google apps installed and no visible chinese bloatware.
Played around a bit for a few days then enabled developer settings and by accident checked some screen / hardware acceleration options.
Immediately after, the eink display did not update showing vertical lines. After rebooting, I still see the Hisense logo and immediately after that, vertical lines / glitches.
Obviously, the phone works as I can answer calls (by sliding my finger "blindly" across the spot the UI elements are) but I cannot see what I am doing as the screen never refeshes anymore. However, I can confirm the screen itself is working as it cleans/resets and shows the clean logo after a reset. Immediately after that, it freezes again and shows vertical lines only.
I tried holding down Vol down + Power and resetting the phone (deleting user data as fas as I could translate the CN font) but that did not reset the system / wipe the settings.
As the screen does not respnd / update, I cannot even select the transfer mode after connecting a USB cable. ADB cannot connect the device.
Can anybody help?
Thanks!

in case you don't have bonded google account, boot into Android System Recovery <3e> (in english language!) and factory reset device.
Warning: Don't do this if you forgot google password, factory reset from recovery mode will trigger FRP lock.

Hi and thanks for your advice.
I was able to reset the phone via the VISION recovery (I don't know why the phone did not load into bootloader).
For anyone coming across this: I used another phone to translate the chinese text using google translate / camera and found out the reset & wipe option requires you to press VOLUME to confirm. In the past, I only selected the one available option button but that turned out to to be "abort & reboot".
Thanks again!

Hi,
yesterday I forgot my unlock pattern and now after too many attempts to unlock, I am getting google sign in option but when tablet was lock my tablet wifi was off so my google id is not letting me sign in,
So can anyone tell me can I start the wifi of my table in locked mode so i can login with my google account?( I tried the keypad wifi hot key buts is not working) or can I factory reset my tablet (my USB Debugging option is also off )
please help if anyone has any other idea to unlock the table.
Thanks
Guys plz help
If you don't mind factory ressetting try this (BEFORE DOING THAT CHECK IF YOU CAN COPY YOUR DATA FROM INTERNAL STORAGE TO YOUR COMPUTER USING THE USB CABLE WITH THE SCREEN LOCKED, AND DO IT. WHEN YOU WIPE PROM SETTINGS IT SAYS THAT IT ERASES PHOTOS (SO I THINK IT ERASES INTERNAL MEMORY)):
Turn off the tablet, I think you can do it from the lockscreen, if it doesn't work press the power button for a long time.
Turn on the tablet holding volume down and power until some text appears in the bootloader screen.
Then wait for the tablet to ask you to confirm what you want to do before 10 seconds (boot android or wipe data).
I don't remember if it was volumen down or volume up, anyway don't worry it appears on the screen. One of these buttons will allow you to choose what you want to do. The other will confirm what you've chosen. Remember to do this last thing in less than 10 seconds or the tablet will boot android normally.
I hope you can wipe this way without having to enter the pattern.
Yesterday i rooted my htc wildfire s A120b model. Then after rooting i deleted the unwanted files . Accidently , i deleted system files . THis caused continious restarting of the phone. I then used power+ vol down key and did factory reset. Then after doing factory reset the device works
"only once" but you cannot access the home screen only notification bar (which gives acess to settings wifi etc). till the display is on the phone works then if the display is timeout or press power key it goes on continious restart again and you have to repeat the same process of factory reset.
even in recovery mode it gives red exclamation sign. and says e: cant open /recovery / command something like that
now my question is
Is there any way to get the deleted system files via usb cable connecting the pc?
plz help

A factory reset would not restore missing system files. It only wipes user data. It sounds like you don't have a custom recovery either so your only options are:
Unlock the bootloader and install a custom recovery and flash a rom
Run the RUU to restore the phone to stock
There aren't going to be any options to keep your data unless you enabled USB Debugging on the phone and the computer is able to recognize / access it.
Hopefully someone can help me, my child has a Pendo Pad 7 Model no.PNDPP44QC7 with Kitkat 4.4 and it ended up with lots of malware/viruses and barely usable. This tablet only has a power button and no other buttons so I did not know how to boot into recovery mode to do factory reset and after trying reset through settings which made no difference so I gave the device ROOT access so I could try and delete the malware etc but of course i did not do any sort of backup and did not add CWM or TWRP recovery. I ended up deleting something wrong and now the device just hangs on the Pendo logo screen. I have since worked out how to boot into Recovery Mode and also Fastboot mode now but a bit too late I tried to do a wipe data/factory reset and this made no difference still hangs on Pendo logo.
I can't seem to find a CWM or TWRP image file to suit the tablet and possibly try putting tablet into fastboot mode and using ADB on computer and flash the recovery to tablet. ???
in recovery mode options i get are
apply update from ADB
apply update from sdcard
apply update from cache
wipe data/factory reset
wipe cache partition
backup user data
restore user data
but i can not seem to find any correct files to work with this tablet any help to get this tablet working again would be much appreciated Thanks
Good day! how did you manage to boot into Recovery Mode or Fast Mode?
After pressing the power button and seeing the display turn on. Keep spamming the power button and a menu will pop-up on screen with boot options. Short press of the power button cycles through the options, long press selects the option.
Mine was also stuck on a boot loop, even though I had not played around with any settings or tried to root etc. I was able to revive it by going into recovery mode and doing a factory reset.
Hey OP I've got hold of the same tablet I'm working on getting a rom dump atm. Bare with me I'll try and send a link for the img. If u can get into recovery mode where u can update zip. That's good if not try and via pc. Once u have a link to the tablets boatloader, rest is history.
Hi,
Wondering if I can follow up on this.
Mine is stuck on the PENDO boot screen, and I have tried the reset button, as well as the se commands PENDO suggested....
1. Press On/Off Switch (Power), wait for the Pendo Logo start up screen, and then press On/Off Switch (Power) twice right away.
2. Factory mode menu comes out after 10 seconds, two fingers touches panel together to move to select the one like the following picture shows (no need to understand the Chinese words, just follow through as what the picture shows)
3. Press On/Off Switch (Power) and the following picture below will show, press On/Off Switch (Power) again to proceed on Recovery Mode, and wait for system to restart.
Unfortunately, nothing still happens.
ADB will not reveal what device it is, nor will Win 10 recognise the device for it to show in Device Manager or connected devices.
Windows responds with a ding ding, but nothing shows up.
I am stuck, and any info gladly accepted.
Thanks
bump please

not working in my pendotab window 8
Hi,
I could get no further with mine, the same as you.
I contacted Pendo Support, and explained it would work but not boot, I even asked for the image file so I could reload it in recovery mode, however, they did not have access to it, the Chinese manufacturer had not made it available to them.
As I described it was not damaged, but simply not working, they agreed to send me a replacement, even though it was out of warranty, as really, as I said to them, it was not fit for purpose.
I had to send the old one back, but they sent me a satchel in which to do so, at no cost to me.
They sent me the new one very promptly.
Hope is not lost,
Someone has finally manage to extract the factory ROM for the pendo PNDPP44QC7. Just search the model number on needrom.

Hi experts,
Trying to keep my kids from using my own tablet, I recently changed the screen lock and forgot the new pattern afterwards
I have the credentials of 2 google accounts opened on the tablet and my fingerprint is already enrolled on the device, I thought I could live with the finger print but discovered that I must enter the screen lock once every two days !
Now the device is locked, and it doesn't give the option of "forgot your pattern" or reset using your google account.
I'm trying to poweroff the device to restart in recovery mode, but even the poweroff function requires the screenlock pattern. I had to let it till battery is empty to poweroff, and yet I can't start it in recovery mode (power + volume up)
The WiFi is ON on the device, and it's connected to Internet, but though Google android device manager can't locate or connect to it !
My 2 Questions are:
1- How can I unlock the device with my google account or fingerprint ?
2- If the above is not possible, I need the photos and videos on the device :crying:, is there anyway I can unlock the device without needing to wipe out the data and reset it to factory ?
Please help & Thanks in advance.

I believe fingerprints and passcodes are stored locally on the device. They wouldn't have anything to do with Google. Hook it to a computer and see if you can save your files cause it's probably going to take a factory reset to get rid of that. If you can't access the tablet to do a factory reset that way you will probably need to use Odin to return it to stock and start over from there.

Can you access TWRP? May not function on the S5e, but on another device it works to use Advanced - File Manager, navigate to /data/system and then delete the locksetting.db file. This effectively removes the lock settings on reboot. Good luck

Might be a little drastic, but you can follow the instructions for unlocking the bootloader. That will cause a factory reset. You will probably need to let the battery run down. Then, plug the USB cable into a PC and NOT the tablet. Press and hold both vol up and down and then plug the USB into the tablet. This should get you into the unlock screen. It will also get you into the download mode to use Odin.

If he can't get into the tablet at all he's not able to tick the oem unlocking toggle in Dev settings. Don't you have to do that in order to unlock bootloader?

If you let the battery run down and then use the method I gave, you CAN get to the unlock mode. And, no, you don't have to enable OEM or Dev mode to unlock the bootloader and reset the tablet. But after doing it, you will need the google login info, which the OP claims to have.

The device did not has TWRP installed before. and it's not rooted, it is with the stock ROM
Can I install TWRP from Recovery mode while the tab is locked ?
and if that's possible, is there any pitfalls or tricks that I should be aware of when installing & using TWRP ?
I went through searching and reading about how to do it, and got questions
- choosing the TWRP version to download, should I pick twrp.me/samsung/samsunggalaxytabs5elte.html or twrp.me/samsung/samsunggalaxytabs5ewifi.html ?
- I read that the only way to install TWRP without rooting, is through Odin which I never used. but what I read in
getdroidtips.com/twrp-recovery-galaxy-tab-s5e/,
getdroidtips.com/flash-twrp-recovery-samsung-phone/ &
getdroidtips.com/how-to-unlock-bootloader-on-samsung-galaxy-phones/
mentions that the device data will be wiped in the process. Is there anyway that does not involve wiping the data ?
Thank you for your support
Hello!
I bought an Oppo phone from somebody but after I got home I saw that the phone was demo or in demo mode. I google it to try to find a solution, I found a solution to enter my gmail on the phone and to erase it remote and after that "wipe data" would appear in recovery and I would get rid of demo mode. But after remote erase, wipe data didn't appear and the phone got stucked in recovery. I tried to online update but when I press it, it searches for wifi and the power off message appear like I pressed the power button. I tried to manual update with otg and usb stick, the update went well but the phone is still stuck in recovery. Sometimes when it enters recovery, after I select language it gives me this error: kindly reminder, system error, after selet language, please select online update(keep data) to recovery system, thanks!
Any idea to recover the phone? I read about edl mode, msm...Can I do something?
Big thanks!
