Hi Guys,
i decided to open this thread, because in my opinion my questions aren't really answered yet. So here is my question:
I have a Stock Infinity with 9.4.5.21 ICS Firmware and i want to get my NVFlash Files and finally install a Custom JB ROM on it.
But i don't really know in which order i have to follow the already postet guides. I think i have to do it as follows:
1. Unlock Bootloader with official ASUS APK
2. Gain Root (f.e. with the one-klick-root-tool)
3. Proceed with Nvflash (to make it Brick-Safe, because it seems that it happens very often)
4. Install Stock JB Firmware from Asus (But how to flash it?)
5. Flash Custom Recovery (f.e. TWRP with GooManager)
6. Flash Custom ROM (f.e. Clean Rom)
7. Be happy to have a non-bricked TF700
Can someone plz help me to verify these steps? I'm sure it will also help others who aren't certain about unlocking, too.
I would do this:
1. Unlock with the official tool and void your warranty, hope that Asus' servers work.
2. Root is not required at all for using fastboot or a custom recovery.
3. Do the NVFlash backups using fastboot and nvflash. Copy the created files from the tablet to your PC before you flash anything else.
4. Install a custom recovery using fastboot.
5. Flash the Asus JB firmware to get the JB bootloader. AFAIK this can be done from the custom recovery.
6. Restore custom recovery using fastboot, it was overwritten by the Asus JB firmware.
7. Flash custom ROM. If you use CleanROM, it's already rooted.

I see issue with your process. After step 4 (install Stock JB firmware from Asus site), after this you no longer have root/recovery, so you can't proceed to step 5 using GooManager. You should follow _that's recommendation, however at step 5, instead of flash the JB firmware, you just use fastboot to flash JB bootloader only, then you don't need his step 6. Go straight to step 7 (use custom recovery to flash custom rom).
Thanks for your help!
So now I think it should work like this:
1. Unlock Bootloader with official ASUS APK
2. Proceed with Nvflash (Afterwards boot into Stock Android to save NvFlash Files before continuing)
3. Install TWRP Recovery
4. Install JB Bootloader with ADB
5. Flash Custom ROM (f.e. Clean Rom)
6. Be Happy, because now it's unbrickable and ervery Custom Rom can be flashed
But i dont't know what I have to type into ADB to flash JB-Bootloader and where to get the Bootloader-Only-File?

PM me I give you JB bootloader zip file
No ADB, just use TWRP to flash JB bootloader just like you flash a rom.
I finally made it without bricking it
If anyone else have questions, feel free to ask me!
And thank you guys for your help

hi
first sorry for my bad english
My tablet was on 4.0.3 Offical Version , I unlocked it and succesfully root it
Today i Flashed cm-10.1-20130105-NIGHTLY-tf300t with wrong CWM !
For now , i can go to recovery and USB Flash .
But i dont have any rom in my sd card except cm-10.1-20130105-NIGHTLY-tf300t
I Use Cwm back up my "offical 4.0.3" rom before install CM10.1 but now when i restore that it doesnt work and My Tablet hang on ASUS Logo
What can i do ?!
To switch from ICS 4.0.x to JB 4.1.x or 4.2.x (which is CM10.1) you need to first flash the actual official rom from ASUS, flash a new bootloader, i recommend TWRP at this point, via Fastboot.
To flash the official rom you need to unzip it once and then flash the new zip.
Then flash a new bootloader for JB via fastboot.
Now flashing CM 10.1 should work fine.
When I'm in this situation i use my external sdcard to get new roms to my transformer.
If you don't have a micro SD or aren't able to get to it without the transformer you should use ADB Sideload.
Therefore:
-update your android sdk (Tools and Plattform Tools)
-flash TWRP with fastboot: http://teamw.in/project/twrp2/97
-install a new rom with ADB Sideload: http://teamw.in/ADBSideload

After unlocking bootloader OTA Update will not work and there is no way to "lock" bootloader !
Come on... What you are asking for is in the first sicky post on this section... Here is the link.
Hi folks! It has been a while since I have been on this forum; and I have a question about how to update from 4.1.2. to 4.2.2.
The process is not quite clear to me. Can I just download the Asus Firmware and flash through existing TWRP recovery (4.1.2 version)? Do I have to flash a kernel and new recovery using fastboot first? I see some step-by-step guides but also a view warnings. It is a littlebit vague to me what to do.Can anyone guide me through the process please?
I am on Hydro 7 but looking to update preferably to another custom 4.2.2. base rom. Tips are welcome
Best way is to download the firmware from asus website extract it (theres a zip inside the zip) and flash it with twrp, this will get rid of twrp so after the first boot find the approprate version of twrp and reflash it with fastboot, from there you can flash custom roms/ kernels at will
goodluck
I'm not sure if twrp will work. My upgrade path was to use fastboot the official zip from the Asus website, then fastboot twrp. Be careful which version of twrp you fastboot because it will cause a brick. I think twrp-2.5-4.2 should work for the US version for the official blob from the Asus website. For the WW version of the blob I used twrp version 2.4-4.2 successfully. Good luck!

Hi
I'm also still running 4.1.1 on my TF300TG (WW-version).
The bootloader is unlocked with the asus-tool, cwm-recovery (CWM-based recovery v6.0.1.3) flashed with fastboot and the system is rooted with supersu.
Now i want to update to 4.2.1 but it won't work. neither with the SOP for manual update nor from cwm-recovery.
From what i found it should work like this:
- download the 4.2.1 (10.6.2.6) rom file from the asus website
- extract the zip (once)
- open the second zip and open \META-INF\com\google\android\updater-script
- delete everything except "assert(package_extract_file("blob", "/tmp/blob"), write_raw_image("/tmp/blob", "staging"),delete("/tmp/blob"));
set_progress(1.000000);"
- save file and save the zip
- put zip on sdcard and install from cwm-recovery
can someone tell me, if this is correct? or if i should only flash the blob with fastboot?
any help is appreciated!
thx!
My device:
- TF300
- Android 4.2.2. / CM10.1 (10.1-20130621-nightly-tf300t)
- WW_epad-10.4.2.9-20120809 (= 4.1 bootloader version)
- TWRP 2.6 recovery (for bootloader v4.1)
My aim is to update to CM10.2, therefore I need a bootloader version 4.2. I downloaded the latest firmware from the asus-website (TF300T-WW_epad-10_6_1_27_5-UpdateLauncher.zip) and put it on /sdcard.
But I'm in doubt:
- Is the asus firmwire described above the best way to upgrade my bootloader? And can I use TWRP to install this zip?
- If so, do I need to change the TWRP version to 2.6 ready for -4.2 (teamw.in/project/twrp2/97) not at all, before or after I installed the new bootloader?
I know bootloader/recovery issues can easily brick a TF300, so to be sure I ask. Thanks in advance!

I flashed the blob via fastboot. Then flashed recovery via fast boot. Then cm10.2 from recovery. I was on old June build of 10.1 and 4.1 bootloader same as you. Be safe fastboot flash follow guide in q and a section

Same question, but not exactly answered: can you do this without a cable connection with your pc?

Honestly, I'd rather be safe than sorry when upgrading bootloaders. So I would always suggest using the cable connection because it is less likely to fail. You probably could get away without using it to flash stock, but you wouldn't be able to flash TWRP without fastboot, and then couldn't flash a custom ROM. But everything feels safer once you have Nvflash backups.

I was in the same situation as you not so long ago. Was on 4.1.1 with TWRP 2.6.3.0 JB installed. Asked myself these questions repeatedly. I updated via fastboot to the staging partition using the blob within the latested ASUS firmware zip file. The blob file contains, bootloader, recovery, system and boot. This means your are essentially returning to stock everything upon flashing. This was a huge sigh of relief as I didn't want to brick my device because of the same concerns you have. So I flashed via fastboot to 10.6.2.10 then flashed to TWRP 2.5.0 4.2 as 2.6.3.0 didn't work for me for some reason. I heard a number of people say that 2.6.3.0 4.2 is buggy and suggested to stay with 2.5.0 in which I would recommend from experience. Then flash your custom firmware.
Pretty lost by now. I am still (sick of it) on an unlocked Asus stock 4.2.1 with TWRP 2.5. My intention is to change the ROM but was considering CM 11 which I understand does require TWRP 2.6.X at least. I was hoping for a fix for installing navflash on post JB but I believe does not possible so anything that means touching the bootloader makes me very concern.
I was wondering:
- Can I flash TWRP 2.6 (4.2 img file i beleive) directly from my already installes TWRP 2.5 bootloader and then install CM 11? or do I need fastboot process again?
- Is CM 11 worth on the TF300? I just need some stability and reasonable speed after having so many problems with the stock rom.
Thanks.

Yes, CM11 requires TWRP 2.6.3.1.
You can install NvFlash on a JellyBean Bootloader, link and guide is in my signature.
If you bootloader is above 10.6.1.8, you can just flash the TWRP 2.6.3.1 and then reboot and then flash CM11 + gapps.
I think it is super smooth with the OC Kernel.
Hello all,
I consider to install a custum roms on my TF700T, running Android 4.2.1, Build number JOP40D.ww_epad-10.6.1.14.10-2013081
I already know that I have to take the following steps:
1. Unlock by using the ASUS unlock tool
2. Root
3. Install TWRP recovery
4. Select a Custom ROM
After a lot of googling and searching on this forum I am still not sure how to root the tablet with this build number. Can someone help me out? Any other tips are welcome as well of course!
Thanks in advance!

You currently can't root 10.6.1.14.10 without a custom recovery. But you can install TWRP via fastboot on an unlocked unrooted tablet, then simply install a rooted custom ROM from TWRP.
Hi,
Here is my situation:
1) Recieved OTA Upgrade to Lollipop CM12s, not very comfortable with some features gone or not as expected.
2) Looking to go back to CM 11s
3) Unlocked bootloader, flashed custom recovery twrp, rooted
4) Created backup
5) Downloaded the CM11ROM and Updates to be at CM11s
Problem faced:
While flashing CM11 ROM, its failing.
Question(s):
1) Do I need to flash the CM11 firmware and then flash CM11 ROM?
2) Can someone guide me to the steps from here (flash CM11 firmware->flash CM11ROM) and correct firmware files for CM11s?
Relatively new...and don't want to fool around and get bricked
Follow these instructions: http://forum.xda-developers.com/showthread.php?t=2765455
pretty much: download the files, flash it through fastboot and NOT recovery.

So you are suggesting:
1) Device in Fastboot Mode:
2) Copy the Firmware and ROM image in the same ADB and Fastboot Directory
3) Flash 11s Firmware .... (command)?
4) Reboot in Fastboot or just Flash CM 11 ROM right after the firmware flashing?
5) What command to run to flash the ROM in fastboot?
I guess I am confused with the order of execution and commands .... can you help me with that please?
