I feel like an idiot for asking, but I'm having issues with the ROM part. I'm used to working on HTC phones and this tablet has been a little different for me. I have unlocked the bootloader and flashed twrp thru fastboot. I'm confused on how to flash the roms. The tablet doesn't show up like my phone does on my computer so where do I place the zip, Second question is can I get to recovery thru fastboot like on my phone. It was as simple as fastboot recovery, but I don't see this in any guide. Any help would be appreciated. And an FYI I do not have an sdcard.
Hi,
to install the rom is like all the other devices but since the last OTA update 4.2.1 there are 3 version of rom for our devices
1 based on ICS bootloader
1 based on JB 4.1.1 bootloader
1 based on JB 4.2.1 bootloader
now all depend on which version of android you have when you unlock the device, you can found easly information about that.
to start the recovey you have just to boot on fastboot mode select RCK with the volume down button and push volume+up to confirm
when in verify if you can have access to sdcard and make backup of the system and restart the system to be sure everything works fine (already to many bricked devices around lol)
if you have the bootloader 4.2.1 (last OTA of march) probably you will have problem to access sdcard, this because only one recovery at the moment work on that bootloader TWRP 2.4.4.0-4.2 (not TWRP 2.4.4.0-JB) in any case never install ICS version if you have JB
be carefoul when you will decide to go haed most of the guide are for old versions.

I updated my developer S3 phone from 4.04 to 4.11 using the info from this thread (http://forum.xda-developers.com/showthread.php?t=1974114).
I did step 1, worked like a champ. JB runs great, but I had previously placed CWM recovery touch on the phone (via ODIN) so I could back up first, but after flashing 4.1.1 the phone would not boot into recovery. I would get the blue wording up in the top left corner that it was, btu the phone would reboot then right into normal mode.
I then tried step 2 from th above guide, still notta on recovery. Now the dev mode comes with an unlocked bootloader, but did flashing the JB rom basically lock it?
Im wondering if I need to unlock that bootloader again?
Thanks
Hello,
After a couple of months on cm10.1 on my TF300T 32GB, I wanted to try another rom. I was (and still am) on TWRP v2.2.1.5, and after flashing a new rom (I think it was grimlock) it booted, but would crash after a minute or so of not doing anything. Deciding to flash another rom, I flashed paranoid android and it would never boot anymore. So that is my problem, I am completely stuck, and because I can't boot into android anymore, I can't place any files on my internal SD card to flash.
Is my TF300T beyond repair? Will I have to send it back? I also need some explanation on how Bootloaders/Recoveries/ROMS work on the TF300T, because it's really easy on my Galaxy Nexus but here it's all complicated.
EDIT:
It's also worth mentioning that when starting the tablet while powered off with the onbutton+volumedown it will say that the following bootloader is installed:
"WW_epad-10.4.2.13-20120907" a03
Your tab is not bricked but you are going to need micro sd or mount internal memory via twrp to put roms on your tablet

While as above your tablet isn't bricked, flash the latest version of twrp with fastboot, "fastboot flash recovery *name-of-file*" then move a 4.1 compatible rom over to your tf300 and flash it (id suggest the latest stock firmware from Asus but its up to you)
Its pretty easy on the tf300t, but Asus in their infinite misguided wisdom decided to release a new bootloader with their 4.2 firmware that wasn't compatible with kernels built on prior sources, So now we just have to check if the rom/kernel you are flashing is compatible with the bootloader you're on, 10.4.x.xx is the old bootloader and 10.6.x.xx is the new bootloader, (devs call these bootloaders 4.1 and 4.2 bootloaders because of the versions of android they were released with, the bootloaders themselves are capable of running either 4.1 or 4.2 versions of android.)
Twrp is a recovery and a recovery is a kernel, so if you flash a version of twrp that isn't compatible with your bootloader version, it will not function correctly. Plenty of thread that should point you to the right version.

Thank you both. I will try to fix it with the instructions. I am really happy that I don't have to send my tablet for repairs. :fingers-crossed:
I have been on CM 10.1 for sometime but now cannot get anything past the July 6th nightly to boot. Are new CM revisiions only for the 4.2 bootloader?
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!

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
So, the situation is I have moto g xt1033 with :- unlocked bootloader, rooted, stock rom 4.4.4 kitkat (i mean no custom rom). and fastboot flash mode 41.13 2014-06-16 and philz touch 6 clockworkmod v6.0.4.7
I want to know how to update to lollipop with official OTA update (not manually or sideloaded)?
Why I am asking this?
I got the prompt of official OTA available on my phone and then i clicked yes and downloaded the update. But when i clicked on install, it went in bootloop. It boots on the philz recovery mode and then nothing happens just restart again whatever i select.
As of now, as I backed up, I recovered to the before state of the phone. Do I need to lock the bootloader again or what? The official OTA update is not for me? Then how to get lollipop? I read the soak test etc threads but why not official update ?
Locking the bootloader won't do anything,so don't lock it
Ota update requires:
1.Stock firmware(unmodified and unchanged or tampered)
2.unrooted
3.Stock recovery
That probably happend becuZ your KitKat firmware was modified and you have custom recovery,root..
So just reflash the stock firmware
Do that on your own risk as failing this might brick your phone
Thank me if I helped
Thanks mate for reply.
1. I have stock firmware KK 4.4.4 (though xposed framework & few modules are installed currently)
2. Rooted
3. What is stock recovery? (m noob here)
And i guess reflashing the stock firmware wipes out all user data & apps, right?
Any other alternative which does not wipes out my data?

Actually there is no other way you could do it
i tried everything i could to stop the wipe procedure but it obviously wiped everything
you just backup everything you have got on your internal and external sd card ..
1.Stock Recovery:: Android devices come with Google’s recovery environment, which is often referred to as the “stock recovery.” You can boot to the recovery system by pressing device-specific buttons as your phone or tablet boots or by issuing an adb command that boots your device to recovery mode. The recovery menu provides options to help recover your device — for example, you can reset your device to its factory default state from here. The recovery mode can also be used to flash OTA update files.
2.Custom Recovery::A custom recovery is a third-party recovery environment. Flashing this recovery environment onto your device replaces the default, stock recovery environment with a third-party, customized recovery environment. This is a bit like flashing a custom ROM like CyanogenMod — but, instead of replacing your device’s Android operating system, it replaces the recovery environment.
what you have to do is:
Find the Kitkat official update on the internet accrouding to your [Build number],[model number] [system version] you can get this information in about phone....
If you have asia retail then follow this method http://forum.xda-developers.com/showthread.php?t=2700502
ok Here what i am planning:
1. Uninstall all modules & xposed framework
2. Unroot using supersu
3. Restore/reflash stock recovery (just recovery not whole firmware as I already have stock rom)
4. Install the update either manually via recovery or using auto install.
Am i on right path? Pls help me on step 3, any link or step-t-step guide? I couldn't find one, every post is abt restoring whole firmware.
TIA. Cheers !!
