Stuck on Download Mode Samsung Galaxy Tab S 8.4, How To Solve Download Mode Samsung Galaxy Tab S 8.4

Stuck on Download Mode Samsung Galaxy Tab S 8.4
How to solve stuck on download mode samsung galaxy tab s 8.4

Download mode is used for developer to download software needed to samsung galaxy tab S 8.4
in my case i was going to root my tablet, but unfortunately i choose wrong CF auto root file and different odin version. So step by step instruction instructed on google stopped working and my tablet got stuck on download mode.
some people recommend to remove and re attach the batery to solve this problem, however as samsung galaxy tab S 8.4 has unremovable batery i need to come up with other solution.

to enter download mode we need to press 3 button at the same time and hold it for some seconds,
those three button are; volume down button, power button, and home button.
apparently to solve this download mode problem we can use the same button and same action, for my samsung galaxy tab S 8.4 i just did the same thing.
press volume down, power, and home button together and hold it for a while, but it took longer time than when we want to enter download mode.

hope it can help you 🙂

this is my warning message when i try to run my program

How to get admin privilege in Windows

How to get admin privilege in windows? how to create admin account in windows? how to clear and reset windows user and password?

i have been trouble with this issue since i dont have any account with admin privileged in my newly given laptop. the result of not having this administrator privilege is that i couldn’t install any software i want. i couldn’t event change the desktop background. demm…

up until that time i don’t know that there is a way to get admin privilege, create admin account, or clear and reset windows user and password. (or i know but wont bother think about it because i didnt have any issue with my own laptop).
so the solution was to install my own windows os as second boot/first boot. this method will leave the laptop with 2 windows operating system and separate folders, because i choose to install my own windows 7 in different partition (you should to this too if you want to install second, or third operating system. Partitioning harddisk is easy task to easily managed different OS)

but after browsing/searching for a while i get even brighter solution!. Hiren Boot :)…. this Hiren is crazy software. these are steps you need to get admin privilege in Windows

1. Just download and copy hiren boot to CD or create flash usb bootable and make your laptop to first boot CD or flash usb disk.
2. you will then will boot to hiren CD. press enter to continue boot.
3. Hiren software will display list of programs that can be use to tweak your laptop. Choose offline password changer for windows. or something that sound/look like that. (containing words ‘OFFline’ or ‘Password Changer’). press the number of that list (example : 4. Offline password changer for windows). Press 4
4. Follow the instruction. the simple step would be edit user privilege.
5. Choose edit user account/user privilege.
6. Choose user to edit and do the editing, make that user as an administrator.
7. Save.
8. reboot.

The next time you boot your account that has been granted admin privilege will be displayed as administrator account in control panel.

download the hiren boot here

Now, you get the answer of these questions :).

User that has examined ticket are free to enter or go in or out the place, for example once u have logged to, in new tab or window, you don’t have to enter log in information again, because your log in state has been stored by your browser through http cookie.
