Is there a way to backup the current ASUS OEM ROM 9.4.5.26 before starting the rooting process?

Thank you!

Supposedly you need to unroot for automatic OTA updates to install. You can also manually apply updates with the method in this thread. To do it manually you actually need to have root.

The only way I know of to backup a rom is with a custom recovery and to get that you must haven your bootloader unlocked. Rooting is not needed but makes installing (TWRP at least) a custom recovery all that much easier. It's not a huge process to root this device, and using the tool provided here takes just a couple of minutes.

You'll no longer be able to receive OTA updates from ASUS when you unlock your bootloader, however that isn't a problem. The odds are favorable that someone will keep a copy of the their OTA update file, and it's trivial now to make that OTA update a TWRP flashable zip which works with unlocked devices. That's how I based this ROM.

Also, just so you know, this ROM is the ASUS ROM- the only change is that it's been deodexed. If you want, you can go to ASUS site from the link in the OP and download the ASUS Official 9.4.5.26 ROM.

Once you unlock and install TWRP, you can also back up your current stock ROM in TWRP.

The only thing you can't do is re-lock your bootloader. Unlocking the bootloader is permanent as of right now.

You may not have any luck unlocking- I've been reading that there's problems with the network connection when trying the unlock tool. You may want to check it out and post here.

Thank you for the prompt response. You rock!!!

Can now flash the ZIP without losing TWRP or needing to run through fancy hoops.

Could you please explain what the problem was? I'm trying to create a blob myself, with no luck.

Sure!

I had to use a kanged version of blobpack. I was having problems where the blob just wasn't updating on reboot. I ended up PMing the dev for TWRP, since his worked flawlessly to install recovery. He pointed me in the direction of the CM9 blob tools. Following his advice, I just kanged the latest blobpack source with the CM9 repo files, compiled, and blobpacked with -s to sign the blob, and that worked fine!

If you want, you can download the windows EXE blobtools I used here (MD5: 741152b9e6b97eb2050edb8fb02f46e5).

Just don't forget to pass the -s parameter when using blobpack!

Kernel packing

blobpack -s \blob(target file) lnx \boot.img(source file)

Ah, I used the blobtools from https://github.com/androidroot/blobtools. They don't have that parameter.

EDIT: Where can I find the source for your binaries? I'm on a Mac... :/

Just merge the files here with the official blobpack project sources and compile!

Credit to Dees_Troy for this! He helped me out when I had the same problem.

Still Tries to Download OTA "Camera Firmware Update" after Flashing 9.4.5.26

---

Hi Guys, I am rooted, twrp recovery flashed, and I just flashed this ROM. OTA updates are still coming through in the notifications panel, saying I have a "Camera Firmware Update" even though I am now on 9.4.5.26 firmware. However, when I cancel out and go to Settings > About Phone > System Updates, it says "No Updates Available". Really strange... I want to be finished with the updates for now, so wassup??? Anyone else having this issue?
