[Q] TF300T upgrade 4.1.1 to 4.2.2 - Transformer TF300T Q&A, Help & Troubleshooting

Hi!,
I have my asus TF300 unlock in version 4.1.1 with the BlueROM (this is since Oct 2012).
I would like to go for 4.2.2 (mainly flash 11 support is the cause)
Ive been searching and I can see a lot of brick devices...
Mine is already unlocked and rooted in 4.1.1
Is there any guide to go for 4.2.2?
Do I need to:
- update bootloader
- install room
- root 4.2?
Or what? I am confused...

update done with success!

hey im in the same boat. im on an old CROMI rom 4.1( rooted and unlocked boot loader) and i want to go to stock 4.2 and then re-root.
how did you complete this. im worried about bricking it.
i was planning on flashing the stock 4.2 (10.1.6.15 update) from asus then rooting it with the new method to avoid bricking.
is this what you did?

I'm afraid it didn't work.
I tried the oldest version though, the only one with the sh script.
Hello,
I managed to run the latest version and it seems we've got a problem. Apparently Transformers and Nexus 7 are not "permeable" to the exploit.
Needs to be investigated, there is a post in the Nexus 7 section...

[a700] Stock JB update or CM10

Just got my a700 today and enjoy immediately got a notification that the JB update was available. What I would like to know from some of the more knowledgeable members (and almost everyone is more knowledgeable than me) is should I go ahead and install the Acer JB update or should I root, unlock the bootloader and install a custom rom? I. have read that because Acer has not released a certain type of code, that with the stock JB update I will not be able. to root or unlock the bootloader.

I have flashed my a700 to Pawitp's latest CM10 Nightly build. the screen reaction is better than the stock one. And all the stock apps are removed. Nice!! But once my a700 suddenly rebooted, maybe the conflict of apps. All in all i will suggest flashing to the CM10. Sorry for my poor English.
Stock JB ROOT or CM10 ??
Hi,
sorry if I post here but I can't post in Android Development forum.
I could not resist JB OTA when I turned on for the first time my tablet
Now, can I root OTA firmware??!
I unlocked the bootloader and I tried flash CWM recovery, unlock work, but CWM didn't work :/
Can I now flash CM10? How? (back to ICS?)
Sorry for asking too many questions and my poor english
Thanks
Regards,
Lorenzo

Hey,
Your CWM doesn't work, as it's for the ICS Bootloader. They (Germans) have a CWM for JB, but.... due to issues in the past with some early CWM's, a lot are a little afraid to use it. I haven't seen a lot of problems on the German site, so maybe it is ok. I have it installed on my 701, but haven't had the need to use it yet.
As with root, wait another day or so, and my Mate Civato will finish the modded boot.img for the JB 700, so you guys won't have to do a mess of things.
Will be a simple root.

[Q] Upgrading to jelly beans manually

Hello guys.
I'm sorry for the noob questions, but I'm very new to the Android world.
I just bought an Asus TF700T and I decided to root it.
This wasn't possible as my device had JB installed, so I decided to downgrade it to ICS with a method that could keep it locked.
After that I rooted it without any problems
First of all my first question is this:
Is it normal that my tablet now is full of chinese applications? I downloaded the firmware from the asus site so I'm just wondering why it is like that and how to fix it
Also is it normal that I don't have the google play store application installed?
After this I wanted to know the correct steps to upgrade it again to JB keeping the root at the same time
Thanks a lot
Sounds to me like you flashed the Taiwanese firmware.

ye you are totally right...
I'm trying to install the WW version now.
Anyway after I installed it and rooted it how can I update to the latest version of JB?
thanks
Edit: I tried to download Root Keeper and to update it to JB, but the root is gone
So I'm stuck at the upgrading part
You need to install voodo before you update to JB, save the root and then temp un-root it.
If that doesn't work as easily as that (which it didn't in my case) then follow this guide

That worked great for me

root method after unlocking on 4.2.1?

hi recently update to the oficial 4.2.1, and was wodering since its a rather recent release if its been rooted yet
If you are unlocked, as the thread name indicates, you can easily root it.
Follow the guides, but be really careful to pick the right TWRP version: 2.4.4.0-4.2
You can easily brick your tablet using the wrong one.

[Q] Rooted, unlocked on 4.1.1, How can I update to 4.2x?

I have a rooted and unlocked tf300t running 4.1.1 and CleanRom 2.5. After being away from the scene for awhile, I came back to see that they had released 4.2 for my device. Is it possible to update my device to 4.2 or am I stuck at 4.1.1 seeing as how I am not running an Asus firmware. I am really overwhelmed right now, and getting very frustrated. Any insight would be a tremendous help. Thank you very much for even taking the time to read my post.

I would say....
Return to stock Asus ROM v4.1
Reflash appropriate recovery...
Once stable, flash stock Asus 4.2...
Reflash appropriate recovery which will be different than 4.1 recovery.... Read the twrp thread carefully for info on this. If in doubt, there's an upgrade guide in the general section.
