Major Problems. Please Help ! - ZenFone 2 Q&A, Help & Troubleshooting

I have an Asus ZenFone 2 4/64 w/ a 128 gig card. In the middle of watching a YouTube Video, the screen stopped responding to touch. However it would respond to Google voice commands. I restarted it a couple of times with no luck. I then tried to boot into recovery mode and it gave me the android guy with the open stomach and an error message. I then tried to use Asus PC link and was able to navigate the phone that way. So I decided to do a factory reset. Now I have the android guy with the open stomach with his guts turning around and it says erasing. It has been like that for at least 20 minutes. I know it doesn't take that long to reset the phone and whenever I reboot it, it goes right to that screen. Also, on the initial screen when you boot into the system, it says that my bootloader version is unknown, the HW variant is not listed, and the "signing" and "secure boot" both have question marks next to them. Someone please help ?

when you see dead android guy hold volume up and press power button see of that works.

Onda v712 I got stuck in upgrade process

Hi all,
I'm really stuck, cannot find a decent tip on the web anymore and need help!
Problem:
Onda v712 tablet is not starting anymore. I can press the "on" button and the only thing that happens is a backlight that turns on.
History:
1. I ordered the onda tab from a webstore in china and it worked great
.... only the market was not working and I could not get rid of the chinese apps that were pre-installed!
2. So I needed to get the superuser rights and install a new ROM. I followed a guide on the web that was for my device:
**New** Root and Full Working Play Store and Google Apps/Root-Explorer Google it and you wil find it (I cannot post a link)
3. In the recovery mode I started the upgrade and it started to run, first ok, then a error about the patch.zip the device rebooted and ended up
stuck in the start splash screen. On my tab it follows after the white android robot image. I waited a while but nothing happened. Everytime I
booted I ended up at the same screen.
4. Usb was not connected anymore and I didn't know any other way to get into recovery other then (adb reboot recovery command from my
laptop)
5. Found a tip on the www that described a button combination for the recovery mode. I pushed the home button and the reset button for 10
seconds. It rebooted and "something" happened because from this moment on no white android robot was shown anymore. I got stuck with
only a backlight or very expensive bad working mirror!!
Everything that I can try from here is very welcome. :good:
Sub questions:
I like to find out how to get into recovery mode again. (what button combination is it)
I also like to know when a tablet/phone is really bricked and how you know it for sure.
I managed to get out of my deadlock!
Somewhere on the web i found this tip about how i could get into recovery:
Next I held down the HOME button while pressing the Reset button for 8-10 seconds.
Keeping the HOME Button down, I them pressed the Power button and held it until I saw the White Android.
Releasing only the Power button I held the HOME button for 4-5 Seconds longer.
The White Android changed to a Big Green Android with some rotating shape in front of his chest.
From there i upgraded succesfully to 4.1.1 and firmware v2.0

Stuck at Google logo screen

So, it's been a fun couple of days.
I was 'tabling' away, as usual, and my tablet suddenly reboots (if it matters, I was just opening FPSE, as I'd done dozens of times before; Skype was on background; every other process was finished). 'Ok', I thought, 'that's weird'. When the tablet's done rebooting, the lockscreen shows up, and when I try to unlock it, the scren just freezes. Couldn't turn off the screen, nothing. So, I force a shutdown by pressing the power button.
When I try to turn it on again, it just stays stuck at the Google logo screen. I tried going in through recovery, but the result is the same. Select recovery, Google logo shows up, little android with exclamation point doesn't.
I tried formating through fastboot -w, but the process just keeps endlessly deleting, while doing nothing at all. I have to quit command line, shut down tablet or unplug the USB cable with a command line message showing up (I once left it while I went for a coffee; two hours of deleting nothing at all). Same thing with trying to unlock bootloader to maybe going to recovery after flahsing a custom recovery.
I don't mind losing everything I had. All pictures are recuperable and the rest is either in the cloud or in my phone/PC. The most annoying thing would be to set up the whole thing again, wich is no trouble at all (that and going through PvZ2 and TD Bloons 5 from the start :crying: ).
I was using Android 4.4 (KRT16S), everything stock.
Is it bricked, soft-bricked, did the aliens get it? I am e-mailing with someone from the store I bought it from, hoping for a solution or (worst case scenario) RMA, but I would rather solve this without having to.
Try flashing system.img, recovery.img, and boot.img, by hand.
Your emmc likely got corrupted
How do I do that with a locked bootloader and no access to recovery? Is it possible?

OPPO Keyboard has stopped working, leading me to stuck on a fastboot loop.

Please help. This is a serious matter for me.
Started having this problem at February 14th, 02.10 AM.
Have been looking for the answers in the Oppo Forums too but still got no answers.
Okay, I have a habit, which is moving all of my applications from my internal storage to my external SD card, after I let those applications doing their functions and programs and features and so on for a while. It's not a big deal for me to set up my phone again after I restarted it, and usually it works perfectly. Just restart and I would get to operate my phone again. However, this time, I got a bad luck. The worst one, considering the fact that I'm all-around-gadget.
Here's the results I got from reading a lot of threads (not only from this forum and OPPO forums):
OPPO Swype Keyboard has stopped working? Really?
After restarting my un-rooted Find 7 (9076), I cannot type the password on my lock screen. Like any other Android devices, it would always come back to it's system or default applications, I knew that fact. But this time, when I touched the blank space to type my password, nothing came out. No OPPO Keyboard, which happened to be OPPO's default keyboard. No other keyboards. None at all.
So, I cannot do one single thing to my phone except just turn it on and stared at it like a complete idiot.
Then I decided to turn my phone off and turn it on again after a while.
But still, the same thing happened. No keyboards.
That time, I decided to turn off my phone again and pulled out the battery and my external SD card.
After putting the battery back (External SD Card was still outside), and turned it on again, the same thing still happened.
Sliding my fingers up and down, nothing happened. The touchscreen was still there, showing me my date and time even though I was sliding my fingertips up and down.
Not too long after, I felt my phone got warmer and warmer. I tried double-clicking the home button, which I already set to unlock the lock screen, was also useless. The screen was still black and locked. When it got over-heating, automatically I pulled out the battery without even turning off the phone.
That one was my fault. I knew, and well, honestly speaking, this is the first time I'm in this kind of situation. In the past, my Find 7 would just suddenly restarted itself then everything went back to normal, but not this time.
And here's the beginning of my Fastboot Loop.
Fastboot Loop on un-rooted device
After pressing the Power button and the Volume Up button at the same time, it would bring you to the Recovery Mode. When I did that to my Find 7, it brought me to a black backgrounded screen with cute OPPO mascot and some Hanzi (Chinese handwritings). Picture attached.
I tried to wait for 2-3 hours and found nothing happened.
Pulling the batter out and putting the batter back would do the same.
In other words, I am not able to gain access to my Recovery Mode.
Why didn't bring the phone to the service centre?
I thought about this already.
When I tried to connect my phone to my pc, it can detect the phone but cannot access the files because the phone was still locked with the password.
Usually, the service centre requires us to unlock the phone if there's a problem with it, right? In my cases, yes.
I was searching all night to find out the answers.
I found some threads about the Fastboot Loop thing and etc, but they are only for rooted devices.
I'm using:
OPPO Find 7 (9076)
Color OS 2.0.5i Beta
Android KitKat 4.4.2
Device is not rooted, still original.
Still dealing with the same problem until now (the time I post this thread).
Anyone has solved this problem and guide me step by step to finish this?

boot into recovery and format the phone, this should fix it. If you want to backup your data, just boot into fastboot, connect phone to pc, run fastboot command from sdk tool, push custom recovery, flash twrp, make nandroid backup, fomat phone along with all the storage and then flash oppo stock rom (you need to download) or any other custom rom with gapps. To restore use nandroid manager, do not restore system files if you are flashing custom rom.

Thank you for your help Sir.
But, my Find 7 already operated normally again since I left it for a few days uncharged and off.
Then I got into Recovery Mode by pressing Power button and Volume Down button (not Volume Up button) while in the middle of my fast-boot loop.
It worked. I could gain access to ColorOS Recovery Mode.
So, I reset my Find 7, then re-installed my applications and everything again.
Thank you for answering!

G4 H815 bootloop/freeze - "The Call of the Bin" ?

Hey guys long time lurker here !
I'm experiencing an issue with my G4 h815 currently with AICP (rev from around April) and TWRP (from around January 2017).
Since the last update of AICP I did (so back in April) everything went fine with the phone.
I did nothing weird with the phone (haven't installed an app for months, neither droped the phone or whatsoever)
It suddenly froze while I was browsing Chrome, then bootlooped 2 times, couldn't get past the "swipe to unlock" thingy.
I then decided to get into recovery mode with PWR+Volume down buttons => "do you want to erase blabla ?" => YES => "Are you sure blabla" => YES.
The "TeamWin" logo from TWRP appeared once, phone bootlooped again, and until then it just freezes after the second "YES" when I try to get to recovery mode and then bootloops again.
Obviously this crap happens when I'm far away from home (and for a long time) so I installed drivers / ADB stuff on my laptop but I can't get the phone to be recognized by win 10 in any way. ADB says : error: device '(null)' not found
I'm a bit lost right now, any thoughts / keywords that could help me getting sorted are welcome !
Many thanks in advance,
Fosco
Ok I managed to go a bit further ... discovered about the download mode thingy (Vol UP while plugin it to computer).
I installed LG UP, picked a KDZ file here.
I was then able to "upgrade" the phone with the stock rom : Complete success from the process perspective. It then froze on the basic LG logo. I removed the battery, entered recovery mode, reset worked, phone went back alive => "android is preparing apps, etc" but then it rebooted and froze again on LG logo.
Am I missing something ?
EDIT : Tried LG Bridge method aswell ... can't get it to go further than boot ... still freezing on the boot screen
Went ahead, disassembled the phone and heated the CPU ... looks like it needed it-ish.
I am still stuck on the LG logo, but atleast now I have the green android guy having his belly "moving stuff" and the blue led is glowing :laugh:
Nah seriously this is getting annoying ... IDK what to do next ... Cure it with lawnmower ?

Problem with booting G4

Hello, I would like to first tell you the story my LG G4 has gone through and then I tell you the error.
So, at first my phone was working absolutely properly. I accidentally deleted some pictures and to do a recovery, I had to root it. And rooting would be useful for later so why not do it?
So I first unlocked the bootloader through the code from the LG site. After unlocking, the phone reset (because it would be just too good to make some memory changes and nothing more.) But allright. Then I was ready to root. I just booted the phone, everything was fine. I unlocked the developer mode and opened ADB. I rebooted to recovery through
Code:
adb reboot recovery
I was expecting to see some menu with buttons (but that would be just too good). However, I saw just android with a red triangle in the middle. Nothing more. No response to buttons, nothing.
So I thought. Allright, let's boot into recovery using hardware buttons (vol down + power) at startup. Unfortunatelly, it seemed like there is no such mode System just normally booted (and that was just after bootloader unlocking. Recovery mode goodbye.).
I tried to send commands to the phone using diagnostic port. Unfortunately, it responded by FAIL to every command.
I reboot to bootloader and booted an image: "boot-em.img" (from here: google: how-to-root-lg-g4-on-android-6-0-marshmallow-20a20b-firmware. I'm a newbie here. thx for understanding.)
After that the console uploaded the image and booted successfully. Then, however, system started to boot up and was endlessly booting (LG boot animation) till the battery was critical.
I was able to access the EMI number through volume-down button and volume-up button pressed simultaneously.
I was also able to access some factory-reset dialog by holding volume-down and pressing power-button several times. I choosed to reset everything and then accepted it with one more 'are you sure dialog'. System rebooted and was stucked in the LG boot animation.
Then I got to download mode, since recovery mode was lost in hell. Through LG-UP I flashed the original KDZ firmware and everything got back to normal, but recovery mode was still inaccessible through the hardware buttons. I got through the process of setting everything up, getting developer, rebooting to bootloader and I booted TWRP.
TWRP loaded and it responded to double-tap on screen to wake it up. I just checked the menus and let the phone sleep.
After several hours I went back to the phone and double-tapped on display. Nothing. Phone was not responding. I pressed the power button and the phone restarted (I think. It either restarted into the system or was not responding to power button.)
So I got to the system and again rebooted to the TWRP (through fast-boot). I tried to back-up one partition to the disk. During the process phone had turned the display off. So I double tapped. Nothing. I removed the SD card and the phone woke, saying that back-up process was not able to complete. Suddenly it stopped responding to double-tap. It woke up through an interrupt. I re-inserted the card, successfully backed-up the partition to the SD-card and I left the phone laying on the bed plugged in the charger. It stayed that way for 4 hours or so, doing nothing. All of a sudden, a yellow screen was there, (and that's a screen of absolute death that was never supposed to come. Little I knew.) saying that an unexpected critical error happened and to do a memory dump, insert a cable, set up some communication (I don't remember what it was, didn't take a picture of it.) and it could send the memory dump to PC or somewhere. I thought to myself. So, the application is not so stable after all. It said that to reboot just press the power button or something.
And now the problem comes:
The first start: Bootloader booted, LG animation went on and finished. The starting up apps dialog came rolling. Then, system restarted.
The restart: Bootloader booted, LG animation went on and freezed. Then, the phone restarted.
Second restart: The same thing as the first one.
Fourth restart up till now: Bootloader tries to boot and restarts before the LG animation.
I got to download mode and it restarted even there. After re-inserting the batterry I can sometimes get to the Firmware Update window and communicate. There I flashed the official firmware again.
No success, as if I didn't even do it. It restarts before the animation.
Can I do anything with the phone? Hopefully I can. No hardware problem occured (except for a situation where the error could fry the wires inside the mighty System On Chip.)
For the software state I cannot even tell but I might say it's cooked just wrong. That's why I came here.
I know I did some pretty stupid steps. But the error was not done by me. It worked fine and after the yellow screen which came by itself, it just (some bad words).
Thanks for replies.

Solution
So, I was looking around and believe it or not, this problem disconnected the pins on the motherboard's snapdragon 808.
I think this happened: The device, although it was heated many times during its life, it withstood that so far.
However, a longer run of the TWRP had finished it off. Memory got disconnected while running and it threw a yellow-screen.
Pins got disconnected and from then on it was just a standard common LG bootloop issue.
The continuous process of dying (First it partially loaded, then only animation, then nothing) is explained by this fact that the pins were so-so there and a couple of reboots just got it totaled.
Temporary fix:
Pre-heated the memory chip to 250°C using Hot-Air gun. After 18 seconds at this temperature I pressed the memory on top of the snapdragon down to the board while cooling.
Then I added a little metal square on the metal part that is covering the system on chip. This part is over the SOC where before there was just some tape.
This can work for several days in sleep mode or a couple of 'heat-demanding' operations on the phone.
Permanent solution should be to reball the memory chip on the snapdragon. That's my next step.
