Unbrick ZenPad Z170CG - XDA Assist

It's stuck at the ASUS logo. A friend gave it to me to fix since it wouldn't download apps from google play which led me to believe that it had software problems so I decided to update it. It's worth noting that it kinda bricked itself after factory resetting before the current brick. It wouldn't boot and it was stuck at the ASUS logo, but somehow it fixed itself after several reboots. After it fixed had itself, the problem with not being able to download apps was still present. One time I turned it off and it wouldn't turn back on. I tried to go into recovery, but then I realized that the recovery was gone too. It was stuck at "no command" screen, so the only way to modify the files was through the bootloader. I found a firmware zip with the .bin files in it, so I flashed them one by one and I got the recovery back. Installed the update via a good sd card and it was stuck at the ASUS logo. I sideloaded it through recovery and got the same result. I also tried sideloading it through the bootloader which also gave me the same result. I'm all out of options I can think of. If anyone has any idea, please share it.
Thanks in advance!

[Q] How-to restore a TF300T with the newest firmware that is not starting up

Dear guys and girls,
I have a problem. Since 2 days my tf300t is for some reason not starting up anymore. The start screen does not go away. Before it worked like a charm. I have tried almost everything, I can think of. As far as I know the latest firmware is installed. The problem is also that the tablet isn't in developer mode. So my options are limited afaik to fastboot. I have installed the naked drivers version 0.73. But windows is saying that the device is not started. Only fastboot is started as device. I have tried to reinstall the firmware by usb, but to no avail. It sends but doesn't write... I have drained the battery to zero level. Can anyone help me with this? What am I missing?

I'm also having this same issue. Tablet was working fine and then froze up. After rebooting we are now stuck on the Asus screen with the circular logo going. Waited over an hour with no change. Tried to boot into recovery and recovery crashes and gives me Error! This is a stock tablet that hasn't been unlocked or anything.
Update: Did a Data Wipe and the device rebooted and came up. Doing all the updates again. Hopefully it wont mess up again.
So you have an unlocked bootloader ?

[Completed] Secure Booting Unsuccessful error

Folks, I have seen some threads on here so I will understand that you will probably hate me but seriously none of those did well for me. So that's why I am creating mine. As an owner of LG G2 mini I had been closely focusing on CM12 progress re lollipop that InvaderJohn was working on. There was a camera overexposure issue so I tried to use some working lib files and vendor/lib files and created a flashable file for TWRP recovery. I screwed it up as upong the flash my phone with CM12 didn't boot up. I wasn't able to get into recover thru adb so I pressed volume down and middle button and got myself into factory mode. I did factory reset and was in TWRP recovery again. Good. Then I reflashed the phone and there was an error saying that secure booting unsuccessful. I have LG Flashtools and tot file with dll for my LG D620fr on my laptop. This method I used once when getting the phone bricked and it worked and I was able to install stock 4.4.2 ROM. But this time... not sure why but the tot flash got stuck with 94% and while the phone was supposed to get restarted it didn't and the message above of the secure etc. popped up. I am able to get into my TWRP recovery (weird) but nothing else. I suspect I got my bootloader locked. Is there any way how to figure this out, please? I was trying the fastboot method but my phone is unrecognizeable. Any help is much appreciated.

Sounds like the bootloader is locked.
Check this thread: How to check for locked bootloader? ... but it's for the LG G3.
Best place to ask is the G2 Mini Q&A, Help & Troubleshooting.

[Completed] Verizon LG G4 (5.1) stuck on Verizon Screen after boot

I rooted my phone not too long ago and today during a quick reset to update some modifications I made on Gravitybox, it has gotten stuck in a sort of boot loop. I've tried wiping the cache in modified recovery, booting in safe and download mode, and even resetting factory defaults. But every time I have tried those things, after the LG and android logo screen appear and the Verizon logo screen appears like during a normal boot, it appears the phone is stuck at that Verizon logo screen. I am thoroughly baffled as what to do, because I cannot even manage to get download mode.. I have looked thoroughly throughout the internet but cannot seem to find anyone who has had this problem, so, I decided that maybe someone here might know what to do.
Thanks in advance for any help that anyone can provide!

[Completed] LG G4 h811 unable to factory reset or enter download mode.

Hey guys,
Sorry if the answer to this found somewhere else, tried searching but foud nothing for my situation.
My buddy, who is a super basic user and was not attempting to do anything with his phone, has a G4 that suddenly stopped working and went into a boot loop.
We tried factory resetting it and it got about half way through the apps before stopping, going back into a boot loop and was unable to get back to the same point in the factory reset.
I tried flashing the ROM using LGUP to H811-20o and it said that it went successfully on LGUP as well as the phone itself, but after it rebooted it went back into a boot loop.
Now the boot loop goes faster but is still looping and we cannot get back into download mode to try again or potentially try a different ROM. It goes to the first screen of download mode with the 5 blue dots but doesn't get past that, I've removed the battery waited for a while in between attempts and still nothing.
We can get to the factory reset screen and click yes, it will then go to the green android guy with his cog wheels exposed but then immediately goes back into a boot loop.
Any help is appreciated, even if its just a confirmation of being SOL.

[HELP] OPO can't boot into fastboot/recovery. Stuck at boot logo

Hello.
First of all, i'm sorry if this question have been asked before. Believe me, i've tried searching even through Google's 2nd page but still no luck in finding answer.
I had a OPO 64GB version. It was working fine until i decided to do ROM update. My previous working ROM is "CM13-20160812-somethingsomething-SNAPSHOT.zip". It is rooted with Xposed installed
I tried to update it using TWRP. the update is "CM13-20161216-somethingsomething-SNAPSHOT.zip". It got stuck at "Patching system image unconditianally"(probably wrong spelling there) for more than one hour. So, i decided to force reboot it and it is now stuck at boot logo(not bootanimation)
Thing is, i cant get it into fastboot, nor recovery. it just stuck there and i've tried to Power Cycle but still no result. I tried to plug it into my computer and it does detect it in "Device Manager" under "Portable Devices" with name "A0001".
I wonder if it soft brick or hard brick. I'm asking brilliant mind in here, if there's a way to restore it. I just revived it from broken screen since 2016(talk about bad luck) and i don't want to completely replace as the device is still in good condition.
Also, if there's no other choice then i had no other way than to follow this guide here, which completely unbrick my phone(also losing me 30+ apps)
http://www.androidbrick.com/unbrick-oneplus-one-two-3-3t-qualcomm-hs-usb-qdloader-9008/
or
http://forum.xda-developers.com/oneplus-one/help/guide-unbrick-oneplus-one-t3013732
Nevermind. i got it to work by installing QPST driver. for some reason it enable adb at boot logo(yes at boot logo). got into recovery and recover my system partition(which is broken).
I ask the mod to delete this thread. Thank you
