Been researching the unlock/rooting process for my TF300T and have a few questions. I have the 4.1.1 bootloader.
So the process appears to be:
unlock
flash recovery (for 4.1.1)
backup
flash custom rom
1) Should I upgrade to 4.2.1 first? Seems like not as I have read the unlock process is sketchy on 4.2.1. But many of the ROM's only work if you have 4.2.1, so is there a process for updating to 4.2.1 AFTER unlocking and installing a recovery?
2) Getting root seems to be a separate step on this tablet that I do not understand very well. The phones that I have rooted have always obtained root through a custom ROM, but the threads I read here seem to refer to getting root through a separate step. Can someone please clarify this for me as well?
3) Finally, this may be a preference thing, but it seems that for 4.2.1 TWRP is the only viable recovery. For 4.1.1 I can choose TWRP or CWM. Is there a reason for choosing one over the other? I have used both on my phones and been happy with both. I would default to TWRP since there seems to be issues with CWM on 4.2.1 unless someone else has a valid reason to consider CWM. May not be an issue depending upon response to #1 above.
Many thanks!

I just get my Acer Iconia A700 with android JB 4.1.1 installed.
I want to root it, but all I have found is for ICS 4.0.3.
I also want to keep the original rom.
Is it possible, just rooting, not flashing?
thanks in advance

There are a couple methods you can use, and still maintain the stock image.
Look at this thread;
http://forum.xda-developers.com/showthread.php?t=1953917
2 methods you can use.
a. The CWM method. This replaces your Stock recovery with a custom recovery you can flash zip files from.
b. Alternative method (keeps your stock recovery) This offers the least intrusive method of getting root.
CWM has been known to cause issues in the early days, but it seems the more recent versions have settled down. I still wouldn't advise making and restoring backups though. Just from my own experience.
The unsecure Boot.img (kernel) should be the method I would advise. This allows booting via "fastboot" (like when you unlocked your bootloader) and then "fastboot flash boot xxxxxxboot.img) Then you need only to get Superuser and busybox. Note that in some cases, you will need to use ADB to "push" the SU binary. You can can find the commands in my 701 unsecured boot.img thread here;
http://forum.xda-developers.com/showthread.php?t=1934056 Just don't use "my" boot.image as it's for the 701. Use the one in Vorbeth's thread.

So I've been running the stock 4.0.3 Android on my TF300T for a very long time. at one point Idownloaded the asus provided unlocking tool, unlocked the device and installed CWM 5.5 and IIRC rooted the device in prep to run a custom ROM. I never got around to doing this but now I am ready to get this thing updated to the latest firmware ASUS provides ( V10.6.1.15.3)
There seems to be a mess of issues with the 4.2 bootloaders and such. So being a complete newbie to the world of Android I want to make sure I do not brick my TF300T or ruin it in any way.
As I understand... I can simply download the firmware. Unzip the .zip file to my SD card, boot into the currently installed CWM, install the new 4.2 update and all I will need to do in install an updated recovery for 4.2 afterwards correct?
EDIT: My plan is to use This guide >> http://forum.xda-developers.com/showthread.php?t=2187982 << I just want clarification that I can update to the TeamWin recovery after installing 4.2

Make sure you look into nvflash before you go updating to later firmwares because once you leave ICS you'll lose the option. Im not sure how many people here have access to nvflash because they brought their tf300t with JB pre-installed and dont have the chance to use nvflash as the exploit used is patched. But i was lucky and and took advantage of it while i was still on ICS, i would have bricked my tf300t 10 times over if it wernt for nvflash.
It makes your tf300t unbrickable, and lets you flash back to 4.0.1 bootloader if you have issues with 4.2:good:
And to answer your question yes you can update the 4.2 version of twrp AFTER the update with fastboot
So I finally decided I wanted to flash custom roms on my new phone (Sprint LG G2). I did some research on the pros and cons and the risks and thought I was smart enough with tech that I could figure it out. I was able to root no problem, it was really easy to just follow the top root thread step by step. Now I'm trying to install a recovery method to backup my stock rom and flash new roms and I'm finding it really difficult. I'm following this guide http://forum.xda-developers.com/showthread.php?t=2522965
I chose this one because it is up towards the top of the forum. I installed flashify and set the recovery image to the latest version of twrp (2.6.3.3) like OP suggested. I then backed up the stock recovery and the restore kernel in flashify. I rebooted recovery and there is an error. I read through the post and someone suggested using the previous twrp recovery image (2.6.3.2). Now it works, I immediately backed up the stock rom (with root). Now I'm worried about flashing a ROM when it says to use the most up to date twrp (which I don't have and I'm not sure how to update it now). Also I'm incredibly frustrated because I've reached my flash limit in Flashify because I was switching between different versions of twrp. I'm also worn out reading through posts to figure out how to get my recovery working and up to date. It's taken me like 3 hours now to get where I am. Can I install custom ROMs on an out dated version of twrp? Are there additional risks? Any information or resources on the recovery would be much appreciated.
Hi all,
My Asus TF300T is unlocked (because a "This device is unlocked" message appears when i turn on the device), it has root access, but no custom recoveries installed. My device is on ICS 4.0.3. Build number ( IML74.US_epad-9.4.3.30-20120604), Kernel version (2.6.39.4-00003-gafee6c5).
Can someone give me step by step instructions on how to upgrade my device to JB 4.2.1 with ASUS stock bootbloader10.6.2x and TWRP patched 2.4.4.0 ?
Thanks

Here is a link to the best tutorial I have ever found for upgrading the TF300T. Though written for upgrading to JB 4.2.1, it works for any version, you just have to substitute the appropriate files.

Read through it VERY CAREFULLY and don't proceed until you are completely familiar with the steps you need to follow for your particular situation.
If you have questions, ASK. Don't go forward not knowing for sure what to do and wind up bricking your tablet.
Let me know if I can help in any way.
I'm currently running 4.4.3 on my Nexus 5 (stock, rooted, no custom kernel.) If I wanted to update to Lollipop via flashing the image, how would I go about doing that? I have TeamWin Recovery 2.7 installed. I've read the "step thread", but I want to make sure I'm doing everything properly so I don't mess my phone up. I also want root on lollipop.
From what I gather, I'm supposed to do the following (Taken from the OTA help thread):
1) Download the OTA.zip and copy to my phone.
2) Boot into recovery.
3) Flash the OTA
4) Reboot.
Are there any steps in between that I'm missing? Anything else I need to wipe? I know I need to uninstall Xposed first. I don't care about retaining any information, as I've already backed up my contacts, SMS, and other important information with. I've heard that root is only possible with a custom kernel - when would I flash that? Does updating this way require a GAPPS flash as well?
Thanks ahead of time for anyone that helps me. I know there have been a lot of threads asking similar questions, but I didn't come across any mentioning 4.4.3 and I just want to be positive that the steps are the same.
