Operating Precodure #'s 2-13 - GoTo OP#1 comment

TWRP install - obviously done or I wouldn't be able to flash a ROM (yes, there are other ways but none so easy)

Install instructions:

- download rom zip - done from link

- place on sd card of tablet - done

- boot to recovery - done

- go to advance wipe in TWRP - done

- select data, cache, dalvik cache and system - done

- swipe to wipe - done

- press home icon then install button - done

- select rom file you downloaded and swipe to install - done

- when completed press reboot - done

- allow 4-8 minutes for first boot - done for 10-15 minutes MINIMUM 3-4 times with a completely black screen - one time with a minimum 30+ wait (Could have been an hour - I ate dinner)

Now, some education for you since you're learning:

1> Rooting has nothing to do with custom ROMs. You don't need to be rooted, you just need a custom recovery method. You can flash any ROM onto any device without being rooted.

2> Rooting is a a method to get Linux/Unix "root" account access to the operating system. Android is a version of Linux. You have to be booted into Linux to use the root user account. Thus, if you're flashing via CWM, TWRP, ADP, FastBoot, etc - you don't need root because you didn't boot into the Android operating system. If you're a Windows user, this is the same thing as having your Administrator account in Windows password protected but someone yanks the hard disk from your computer and hooks it up to another. They can access any file because they didn't boot from the version of Windows that has your administrator account.

3> Wiping the system erases the entire OS - thus bye bye Android. If you wipe it, Linux and Android are no longer there, there's not a possibility of extra files still hanging around. (Not there at least) or missing files because they are all gone. The Android OS gets put back in there from what you put in the system directory of your .ZIP file/custom ROM.

I'm not a developer.

I can follow instructions.

I understand the process.

I have been rooting and flashing since the HTC Dream/G1 (first commercially available Android device) which I had since the day before it was available. (T-Mobile sometimes ships faster than the official release date!) Stated to show time frame and not the possibility that I bought it used last week.

I understand you're doing this for fun, not money.

I'm reporting problems to help you which in turn helps me and all the others with interest in this ROM.

SUMMARY:

I don't believe I did anything wrong in my process. I have a perfectly fine working device using a different ROM at the moment and have had two different ROMS working fine after flashing, but not so yet with TOOLROM. The X factors are which keyboard to use, I choose Google in all cases, and how long I should wait. The wait is in the instructions but that amount of time didn't work for me, multiple times. So I'm not here to give you hell, but I'm not here to be chastised or treated like an imbecile either. This isn't rocket science. It's pretty damn easy for someone who is a computer tech since the 80's. Precedent has been set, I can flash to my hearts content and make it work with other ROMs. There is a problem. I'm reporting it. I'm trying to help. Please see this as an assist and not a fight. You're time/work is appreciated. Or, to be honest, it will be when I can get TOOLROM to boot/work. :D Until then, please be thoughtful and read what I have posted as I have taken the time to try to express myself well and provide good information to you in solving the problem.
