Hi guy's,
it is possible to TWRP recovery or CWM recovery back to stock Asus recovery?
Just flash the asus firmware.

Download the firmware you want to flash back to from the ASUS Website. Unzip the file you download to get the flashable firmware zip file and flash that through your recovery. NOTE** You CANNOT flash a .30 or before firmware to one that was already updated to the OTA JB bootloader, it will hand at bootscreen if you do. Also, you must flash to the latest .30 firmware if you are currently on ICS and want to flash to JB bootloader, you cannot simply recovery flash the firmware file to the latest release.
I am now on custom romjb based on asus fw ... I downloaded right asus.it the latest fw based on jb .... please tell me the procedure to get back the stock recovery?
Other question:
it is normal that after flashing a custom rom the twrp recovery remained?
This is my procedure for installation custsom rom;
installed with the fastboot twrp recovery after flashatola customrome if I go into recovery I still have the twrp recovery ... is this normal?
Thanks

I have a asus tf300t running 4.2.1 with unlocked bootloader and root. I am running twrp v2.5.0.0 and I have already made backups of my apps. I am trying to install a custom rom. Preferably PACman rom but at this point any will do. When I try to flash the rom it go through the whole process then reboots but does not get past the asus splash screen.
What is the problem? Is it that the new bootloader does not accept any custom roms, if so how do I downgrade to 4.1? Otherwise I am open to any advice.

You must be on Jelly Bean 4.2.1
with the Asus Stock bootloader 10.6.1.8 and TWRP Recovery patched 2.4.4.0
or
Bootloader 10.1.15.3 and TWRP patched 2.5.0.0
You will find all versions of Stock firmwares and Stock kernels here
And the TWRP recoveries here

I am currently running the 10.1.15.3 bootloader and TWRP 2.5.0.0, yet it still does not finish flashing the ROM. I even tried to flash a more simple stock based ROM, ie. black beans 8. This did not work either. It went through the twrp flash and restarted but when it got to the ASUS boot up screen it simply stopped. I waited about 10 minutes for it to possibly load however it never did. So I am restored back to my stock and am awaiting any further help.

In the OP for PACman rom it says you must be on android 4.1.1 to flash his rom. You need to pick a rom for your 4.2.1. I am also on 4.2.1 and run CROMI 4.6.6 with no issues. Have also succesfully tried the Energy rom. Read carefully the OP for the rom's you are considering and make sure they are for 4.2.1

I am having the same problem! I am running 4.2.1 and im trying to install blackbean 8 using twrp 2.5.0.0. I factory reset in twrp and wipe cache and dalvic. I then install the the rom and reboot but it will not go past the first boot screen with the tegra logo in the bottom right. It always flashes for a second but then does nothing. I have even tried cm 10.1 and it does the exact same thing. I am still able to restore back to stock. This is my first time flashing a rom so any help would be appreciated!
For the latest [ROM][4.2.2][ OFFICIAL] PAC-man v23.0.0 [OC up to 1.7GHz][New Update 22/06/2013], if you read the installation process, you need to be 4.1.1 and not 4.2.1 and also you need installed custom recovery for JB 4.1 BL !
For the latest [ROM]ASU-JellyBean-Hydro 8 (6/29/13)Liquid Butter..- Tf300 -Official 10.6.1.15.3 Base, you need to be on 4.2.1 and 10.6.15.3 bootloader
and you will see to the changelog:
...not sure if any bootloader will work...

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!
Hi... im currently running
CROMi-X v5.2.2, which is based on rom 10.6.1.27.5 with twrp 2.5.0.0 and my bootloader says is the one that came with us10.6.1.15.3-20130416...
To install omni kitkat, im been asked to have the latest bootloader, to avoid screwing up im planning on insalling the latest stock from asus...
However, each time i install a stock through twrp or cwr, the new image not only updates the bootloader and deletes all my data, but rewrites my recovery, for which then i have too reupload using fastboot to upload the recovery...
Is there any way to make sure i dont loose the recovery after flashing a stock firmware... or a way to flash the recovery from the recovery before rebooting after flashing the stock?
Thanks everyone!

Flashing the stock ROM reverts the tablet back to stock, so the recovery must go. Luckily, the bootloader you are on is compatible with the KitKat recovery (10.6.1.15.3) so you shouldnt have to flash the stock ROM at all. If you were on 10.6.1.8, you would have had to upgrade.

Hello.
i have problems rolling back to stock ROM.
currently i have Pacman rom 4.4.4, i tried to go back to official asus rom, downloaded from asus web site.
i read that i need to have 4.2 bootloader, so i noticed that in my TAB i have TWRP 2.8, i flashed to TWRP 2.5, and after that tried to
flash couple of roms,include the official rom, unfortunately, without success. after each flash, i got the asus logo, and that's all.
when i try and get into bootloader, i get the android with a ! mark and i need to re flash boot loader.
after couple hours i flash back to TWRP 2.8 and restore pacman rom.

You can do this with the zip you got from asus as long as the SKU matches what is on your tablet ....
So do this unzip the zip you downloaded .. There will be another zip, unzip it as well ...
Inside that zip there will be a blob file.... This blob file can be flashed using fastboot ...
This blob will return you to stock.... Let me know if you need anymore help ...
Thx Josh
Hi,
I am currently running Zombi-pop 5.02 B4 and has TWRP 2.8.7 Kang on my TF700T. I would like to have nvflash access, can I downgrade to a JB stock version that allows such access? and if yes which stock rom and which boot loader?
many thanks

You don't need to downgrade, you can install the flatline recovery, pull your blobs, then reinstall TWRP.

Really, this is helpful. I was under the impression that a stock JB boot loader is required for nvflash to work. I shall give it a try and report back.
Many thanks
I have successfully done the nvflash access and generated the blobs for my TF700T and stored them in triplicates. My question now is that I have been left with AndroidRoot 10.6.1.14.4 bootloader and a primitive flatline recovery, can I flash TWRP Kang 2.8.6.0 back without problem?
many thanks once again.
Congrats! Yes, flash TWRP kang, reboot, then flash the stock bootloader from here: http://forum.xda-developers.com/showpost.php?p=55238386&postcount=3
Reboot
All is good
Flatline CWM recovery couldn't flash the zips for bootloader and TWRP Kang, so I flashed the TWRP img via fstboot first, then booted into TWRP recovery and flashed the bootloader zip and it worked fine, no bricking whatsoever.
