Hi,
Maybe this is a n00b question but i won't brick my device so i ask the professionals here at xda for advice
I have a Asus TF300T with stock Asus ROM, build JOP40D.WW_epad-10.6.1.27.5-20130902.
My tablet is very slow and i want to tray a custom ROM. I already unlocked the device with the Asus software and when the tablet is starting i see the text "Device is unlocked".
Now i need to install a recovery rom. I have adb and fastboot installed and my device is recognized.
My first question is: wich recovery must be installed?
I checked TWRP and there are different versions.
I see "JB", "ICS" and "4.2" versions till TWRP v 2.8.0.1. Latest version is only available as 1 version and doen's have "JB", "ICS" or "4.2" editions.
My second question is: do i need to rename the file to .blob and flash it with adb? Or can i use the .img extension?
Please help me choosing the right version
Thank you

I just picked up a used TF101 and have been reading the threads learning more about my new ( used ) toy.
The tablet just recently updated itself to ICS 4.0.3 with Kernel 2.6.39.4 & 9..2.1.27 and now I would like to root the device and look at the possibility of loading new roms etc.
I have read the forum until my eyes hurt. Is there someone that can point me at the correct thread to root my device safely?
Thanks

To get root & custom recovery, the following methods are reported to be working with the latest Asus ROM:

I have personally used the first method about a month ago, no problem with my tf101 and the latest ROM (9.2.1.27)

I've can also vouch for the first method on TF101G with latest ICS ( [TOOL]PERI-0.4 One click root+recovery/fix-bootloops+soft-bricks ALL Devices V0.4). Just install it on the PC, run the .BAT file and follow the instructions to root and install Custom Recovery on the Transformer.
The only issue I've had is that its custom Recovery won't seem flash the ASUS stock ROM for some reason. So what I do now is use the above tool to get root and Custom Recovery, then use that to flash ClockWorkMod Recovery v6.0.1.4 NoTouch Hybrid from http://forum.xda-developers.com/showthread.php?t=1855686 - click the Download link and get the cwm-6.0.1.4-notouch-hybrid.zip file (apparently the Touch version is currently broken).
From CWM recovery you should be able to flash any custom ROM and kernel etc., and also return to stock by flashing the ASUS stock ROM from their download site (make sure you select the right one for your model and unzip it first - for some reason they put the zip ROM inside another zip).
If you do return to stock, don't forget you'll also lose root and custom recovery so you'll need to start over.
Good luck!
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.
I recently bought a TF300t second hand and I really need some help! Some years back I was playing around with custom roms on Android devices but im very out of touch.
I would like to install one of the more recent roms on this device. Any suggestion here appreciated.
The device has already been rooted and has TWRP v2.6.3.1 installed. I understand that I need to upgrade this to 2.8. to install the latest roms but im having issues doing that. For a start im unsure how to find out if I have the latest Bootloader 4.2
I really dont want to brick this device!
I tried using ADB to update TWRP but the usb connection never seemed to find my device in the right mode.
The device is currently running Android 4.2.1
Custom ROM CROMi-Xenogenesis 5.4 - 10.6.127.5 WW ODEX.
Any help and advice really appreciated )

Android 4.2.1 is newest official.
10.6..... is bootloader version - newest there is.
flashing recovery and/or ROM will not overwrite bootloader - it stays the same.
You can go to twrp official website and get 2.8.0.1-4.2 blob to flash (unless your target rom states different version needed - see 1st post of yout target thread) - I got it from there - flashed KatKiss using it.
ADB - when android is running.
fastboot - on bootloader screen (booted with voldown+power - RCK / android / wipe data icons) - used to flash twrp blob

Ok got it all fixed now. Thanks!
So, not to hijack, but I'm actually in a similar boat. I'm currently rooted and unlocked on 4.1.1 TWRP 2.3.3.0 and am looking to flash the new 5.0 Rom.
Does anyone have a handy guide on what I should do? Do I just need to flash a 4.4 compatible TWRP version, then flash the ROM? Would like to avoid bricking my tablet.

Yes here you are ....
Get the SKU from your bootloader screen .....
Then go to the Asus website and get the firmware for your SKU ending in 27.5 ...
Then unpack the zip and there will be another zip unzip it you will find a file called blob ....
Flash this blob from fastboot ...
Thx Josh
I have a Asus TF300T that I had BakedBeans on, until I tried to flash to KatKiss. I tried this on TWRP 2.6.0.0 (current version of TWRP installed on my tablet) I saw that it was unable to flash, so I researched and I was told I need the newest version of TWRP to install the KatKiss rom.
Since I have no OS on the tablet (wiped when I tried to install KatKiss), and when I plug my tablet to my pc I get "unrecognized usb device", I am limited to using the external card to do any modifications to the tablet.
I went and got the newest version of TWRP and tried to install it through the TWRP manager, but it says "select zip to install" and the file is a .blob (I don't know how to update TWRP through the main menu I guess)
I have no idea what I should do. I would like a new rom for my tablet, but I will be ok with reverting back to an older rom if that is not possible.
using bootloader version 10.4.2.20-20121228 please help
I managed to find an old version of BakedBeans and installed it, but I can't figure out a way to update do the newest version of TWRP without using the PC USB method, help please.
