Solved-soft bricked Allwinner A23 tablet - Android General

I am not a developer...I have a cheap tablet - Allwinner A23 GT90H, rooted. While fiddling with it, I soft bricked it, where, upon turning it on, the Android icon would show, but it would do nothing else. I spent the last 2 days on the internet searching for the fix for this, and did all sorts of combinations of buttons, etc. The common consensus is that the Chinese tablets do not reset with any combination of buttons.
The 'fix' I found - turn the tablet on, and let the battery run down and die. Then re-start it - the battery icon will show for a minute or so, and then....the OS will load again.
As there seems to be hundreds of people on the internet looking for this info, I thought I would post it here. Hopefully it will help someone.

Help.. Home button always on

hello,
I have a android 4.4.2 brand Alps H900 (Clone S5).
My home button has lost strength and is always minimize windows. Just a little shake the phone turns on immediately, even with it in your pants pocket or in the car is always on.
Yesterday, for more than 10 hours, I tried to do what he found here in the forum, but did not succeed. Installed dozens of applications, also did not work.
I just want to lock the home button (center). So when you load it does nothing.
I really appreciate any tips or help.

CHUWI Vi8 dualboot stuck on boot and not working

Hi, I get my CHUWI Vi8 dualboot 16.04.2015. Everything was ok, it worked very good but at the next day morning I wanted to use it and I find that touchscreen doesn't work. I left it for few minutes and when I look at it again It was rebooting, as it turned out - with no end. I finally turned it of when I lost hope and turn on again. This time I get info that my device is diagnosed, then that it's repairing, at the and I saw windows 8 repair panel but all in chinese. I wanted to choose one of two buttons but touchscreen still didn't working. Next time I used mouse by OTG and by lucky choosing some options I eld to reset. But it changed nothing. Then I get info from seller to click vol+ and power button for 20 seconds. It brought me system selection screen, I choose android with mouse and it worked normally just without touch. I don't what else I can do to fix it. Have you any ideas?
PS: I know it's a cliche but sorry for my english;]

System UI has stopped notification stuck in loop right after Nvidia logo.

I have read several threads on similar problems but none that are the same as mine.
I bought my shield tablet (16gb wifi) off Amazon so I can't really tell you much about it's exact specs. All I know is that I was told that only early manufacturer runs had rooting and OTG issues, and that newer runs had OTG out of the box.
Mine doesn't have OTG enabled, and it would not root with most of the common self installing root apps. So I believe it is an older version.
I have been installing all Nvidia updates as the update notification comes up on my tablet except for the latest one released a couple days ago. (waiting for WiFi to down load)
I was running marvel future fight at the time my tablet did a forced shutdown for a low battery.
Later I plugged it in to charge for a few minutes. When I first plugged it in I got the normal warning image of an empty battery telling me I could not boot yet.
I waited several minutes and tried to boot, but the boot process took an extensive amount of time.
But the real issue is that now I have read several threads on similar problems but none that are the same as mine.

I was running marvel future fight at the time my tablet did a forced shutdown for a dead battery.
Later I plugged it in to charge for a few minutes. When I first plugged it in I got the normal warning image of an empty battery telling me I could not boot yet.
I waited several minutes and tried to boot, but the boot process took an extensive amount of time.
But the real issue is that now, every time I boot it up, once the Nvidia logo disappears instantly before the lock screen or anything else can come up, the notification that one of two processes have stopped comes up. Those being System UI, and Cellular Data.
This would normally be no problem but the instant I click OK the same warning pops back up. It is just stuck in the same loop, process stops, I hit OK and repeat for as long as my patients lasts and I try rebooting...
(why a 16gb WiFi only model even needs the cellular data process is beyond me or why it would prevent a complete boot... )
Any way I started research and found the power + volume down bootloader option.
It took me several tries to figure out how to even get the timing right for that to work. But once there it was no help.
First option for Factbook gave this result :
Cold booting Linux
Then the Nvidia logo, and the same system UI has stopped warningtI have read several threads on similar problems but none that are the same as mine.

First option for Fastboot
It says cold booting Linux the displays the Nvidia logo, but up comes the same warning of one of those stopped processes that will pop up as fast as I can click OK, for as long as I will click ok...
I tried the recovery option and that gave me the error of no command with the dead android with the warning sign popping out of his insides.
Just hit the reboot option and as of right now it did not boot... Will try holding down the power for manual reboot. As it will not power on normally now.
Manual reboot to the options again and going to try the power off option.
I am thinking that I might be able to fix this by flashing from a pic... But I wouldn't know as I have never gotten into that stuff before.
Cellular data stopped is still coming up on boot attempt... Only other option I know to try is open the menu back up and try the recovery again or maybe on the of chance hitting continue might do something different that changes things up and let's it finish booting.
I assume it is not actually completing the boot cycle as I cannot bring up the soft keys nor does the lock screen come up.
(don't get me started on the evils of soft keys. )
Anyway any help anyone can give would be great!

Bricked??? Fusion5 108 octa core

Sorry if this is the wrong place to put this in but I´ve been going nuts for hours and finding no solution to my problem.
I have a practically new Fusion5 108 tablet runing marshmallow. Today I was setting it up on first use and I hate that persistant google search bar. Didn´t find an easy way to remove via settings so I took to Google for answers (ironic I know). I found the same suggestion on several sites: going into apps and disable google app, and restart tablet. So I did that, but when I restarted it got stuck in an ¨optimizing apps¨ boot loop... it did 2 out of 2, then seemed it would start and then again back to optimizing. I was going to try just wiping and reseting from recovery mode, but I get a NO COMMAND when attempting recover. I tried EVERY possible combination with the only 3 buttons it has (power, volume +/-) and even tried a small reset button it has (which just resets the tablet) and still cannot go into recovery. I even opened it up and killed the battery connection and reconnected to see if that helped, the only difference it made was that after doing that it said ¨optimizing 2 our of 4 instead of 2 out of 2 like before. At this point I´m about to just throw it in the trash so any ideas would be useful. I never got to enabling debugging to try to connect it via PC either.
HELP?????

I would look up the Fusion5 website and send them an Email explaining the problem as they may be able to help. I had to contact them when I had wifi connection problem and they were very helpful.....it's worth a try before you throw it in the trash.

Samsung Galaxy Core 2 G355M stuck on "samsung" screen

Greetings!! before anything else, my english is pretty basic so apologies for murdering the language.
This morning i found my very old and beloved Samsung Galaxy Core 2 G355M turned off, i thought the battery depleted during night for leaving some app open like steam or chrome, anyway this happened so many times in the past so i just plugged the phone to charger, turned on and it was stuck on "samsung" screen for more than 2-3 minuteS, that was very unusual and it never happened before so i restarted hoping it was just some random malfunction but nope, the phone still stuck in that samsung screen.
I removed the battery and that didn't fixed it, neither removing the SIM card/chip and/or MicroSD.
I watched some videos (and dozens of websites) about the "hard reset" method pressing and holding home button, power button and volume up button... let me show you exactly what i mean with a couple of videos in spanish, the model they have is the exact same as mine the G355M.
then, what's the problem? well when i do it, my phone shows the green android robot with a red warning sign and then it just restarts, no matter how many times i've tried, soon as the little android guy shows up, the phone restarts, it doesn't show the "android system recovery options" like you can see in the videos above.
BUT WAIT!!! i kept trying and sometimes android succesfully loads (no system recovery tho) and then im at phone initial configuration options, you know, with some "welcome" screen, when it asks for your name, google account, samsung account, wi-fi connection and all that stuff you must fill with a brand new device. I thought the "hard reset" worked somehow but nope, now the next problem is that several android and google services crash while doing this "initial configuration" and sometimes the phone restarts itself and if it doesn't i can't continue because those "services" were crucial and the phone stays in some infinite loop trying to validate either wi-fi connection, google account or my name.
What do you thing happened with this phone? it was working just fine last night, i woke up and saw it was turned off then this permanent "samsung" screen.
Is there any PC software that can access the internal memory or fix the entire phone? maybe i can save some old SMS messages or stuff stored there which now is locked or deleted (coz i did this "hard reset?")
I know nothing about flashing, odin3 and that sort of stuff but im very familiar with PC stuff so i guess thats the only thing lef to do, mess around with the phone, there's too much info around so id appreaciate if you guys point me in the right direction (odin3 tutorial, trusty websites with firmwares, roms and that stuff for ancient samsung devices). Meanwhile gonna read everything about odin and how to flash, thx in advance.
BTW this user had almost the same problem like me...
Samsung Galaxy Core 2 (SM-G355M) - Recovery mode does not work.
Helo! I'm new here at FORUM. In a desperate attempt I decided to create an account here and try to solve my problem with a Samsung device. It all started when I received a Samsung Galaxy Core 2 device to fix. It is stuck on the Samsung screen...
