What I Learned

I finally decided to get around to doing this and ran into a few problems along the way. I thought I would share to save someone else the headache. I started at 3.2.3 and flashed the 5.2.2.rar file thinking I would save some time. That jacked my system all up. Had to wipe everything and start over at 3.2.4. I had backed everything up using the Asus built in backup app. I thought it was nice and easy. That was a mistake that I'll explain in a bit. I made it through all the partial updates and got to 6.4.2. Yeah me. I went to re-install my apps and noticed the built in Asus backup app was missing. Fortunately I had a copy of the APK. I tried to install but in would not let me, even with root. After some reading it appears Asus decided to remove that app along with a few others. Point one before you do this back your stuff up with a different backup app. Titanium is pretty simple to use. I couldn't find any app that would open the .abu backups so I again flashed all the way back to 3.2.4. Reloaded my apps and backed up with Titanium. Then I began the process all over again. Finally got back to 6.4.2. Yeah me again. Well then I ran into another problem I didn't know about / slashed overlooked. This point is very important. In Kit Kat apps get kind of locked down. They basically only have rights to write in the folders they create. Including the camera. For those that don't understand what that means here's another explanation. You have an app that you like that we'll call "Joe's Backup". The app has always given you the choice to save those backups to the Internal SD card or the External SD card. You have preferred the External SD card option for years, but you have to point the app to save those backups to a folder on the External SD card. The app did not create that folder and does not have ownership of it. It just had rights to write to that folder before Kit Kat and now it doesn't. This also affects the ability to copy and paste from the Internal SD card to the External SD card. Point two think about this before you upgrade to Kit Kat. Think about what apps you have that you like to save the data to your External SD card. After discovering that I was somewhat upset to say the least. Well after a lot of digging through vast amounts of useless information I finally found a solution to this problem to. I did NOT discover this workaround. I do NOT deserve credit for it. I'm just pasting the link to where I found the solution. ://winaero.com/blog/unlock-external-sd-card-writing-for-all-apps-in-android-4-4-kitkat/[/url] . I had to erase the usual letter found at the beginning of a web address in order to post. Just add them back in. Follow the directions and you regain the ability to write to your External SD card. You will need a file explorer to do this. I prefer ES File Explorer myself. I'm not pushing ES, it's just what I use. I'd like to point out that you will need the latest version of the app to do this. From what I read several of the other file explorer's have problems with Kit Kat and permissions. Even with root. After I performed the above modification I was able to have my apps write to the External SD card again and finally got freakin Link2SD working again. Ohh what a nightmare. Hopefully this will help a few of you. Hopefully I'll get at least one thanks. As for the functionality of the device I haven't noticed any major problems yet. The tethering still works great. Using it right now. No problem with the signal. I think it does boot a lot faster now and doesn't seem as sluggish as before. But maybe it was time for a rebuild anyways. Also thanks to those who discovered the roots, those that contributed to the project, and to the one who put the post together.

I was at 3.2.3 and made it up to 6.4.2. I discovered an issue that required me to flash back to 3.2.4. I was able to do so with the WW_user_3.2.4.rar file and didn't have any problems at all. Everything worked just fine. After I took care of the issue that required me to go back to 3.2.4 I was able to once again go back up to 6.4.2. Never lost my radio, signal, or ability to tether.

I want to make sure I understand you correctly. Are you saying that the issue with the gsm failing only started after the upgrade to 4.4? Have you tried the other method of erasing your phone that is mentioned on page 10 by ---mablue, on July 20th at 12:27 am--?

Is the problem occurring in a location where you used to have a good / great signal? Are there any other glitches happening that you're noticing also?

Mine has worked starting at 3.2.3, then flashed to 5.2.2, then flashed back to 3.2.4, then every partial up to 6.4.2 and then all the way back to 3.4.2 and then once again through all the partial updates back to 6.4.2. If you must know why I went back to 3.42 from 6.4.2 please see my other post around page 20. The tethering worked the entire time.
