[Completed] Zenfone 2[551ML] 2.20.40.59 update not working. - XDA Assist

Hello
My device is running on 2.19.40.22 & it is rooted.
I am trying to update the firmware to latest update which is 2.20.40.59.
I tried 2 methods, viz:
1. Copying update file in internal memory & restarting the device.
2. Using ADB sideload.
Result
While trying to update from internal memory, it shows installing system update for some time & than shows "Error" with a dead android bot(same which is displayed when entering recovery mode).
While updating using sideload method, it transfers the file successfully to the device & when it tries to install, it says file is not proper.
Please help someone.
Thanx

[Completed] [Q] Note Tab 8 broken

Hello,
I have a Samsung Note Tab 8, China version so it does not have Download Mode so I may be able to root it and install a custom ROM neither can upgrade the Android version to a later Android version. As far as I explore, the tablet has a Fast Boot mode where I can send commands via CMD from Windows 8. Tried to flash a ROM using ADB, but CMD says there is no device attached to the laptop. I am very stuck, and the tablet entered in LOOP when you boot it. Also the tablet has a Factory menu but is in Chinese and I do not understand a thing from that menu. As stated, Android version was 4.2.9 and the tablet model GT-N5100 according to About section of the tablet.
Is there any way I can make it work again ?
PS: All this started when I saw that the Android shown that out from 16 GB of storage, I was able to use only 4, and after I installed 4 or 5 applications the OS told me that I do have insufficient storage to install another app.
Regards,
Cosmin

[Completed] LG Tribute successfully rooted and running cm 12, suddenly cut off from root access.

I actually have several errors here that I need help with.
1. Superuser is telling me to update the binary and giving me two options. Cancel and Recovery Install. The first does what it says but the second brings up an error message, which says,
"There was an error installing Superuser. Please send a log of the error to the developer. "
I click OK and check the log file, but its empty.
2. The file manager tells me that I cant extract the UPDATE-supersU-.zip that I pushed from my computer because I don't have root access.
3. The app Device Control doesn't register that my device is rooted and thus will not function at all.
4. The screen will turn on immediately after timing out. The phone isn't set to be always on.
5. The only way I can boot into twrp recovery is through the app Flashify.
If someone out there helps me it would be much appreciated because my tribute is my only phone and I need it to function

[Completed] The operating system on your device has been modified in an unauthorized way .

I can't check for updates or update my OS (My device is a Tab S) .
I remember using a program that needed usb debugging to recover deleted files from android and it said it would make a one-click root then remove the root after it's finished but the program never worked and got stuck so I unplugged my tab and I suppose it changed something in the system files trying to recover the deleted files or didn't remove the one-click root , I tried removing my sd card then wiping my cache partition but this didn't work . The device was never rootes or modified in anyway , any ideas ? The device works fine except for this .
I would appreciate any ideas .
