you told me to make a back up and put the 2 stock roms and add the root flashable zip.....what do you mean by root flashable zip?
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
On jb rooting is usually done with flashing a zip from cwm or twrp and that is what I was talking about. If you are going to flash a custom rom don't worry about rooting; only if you intend to stay on stock.

The custom roms I have used on this tablet are all rooted when you flash them.

My suggestion was to provide a method of recovery with twrp when things go wrong. For instance when you factory reset wipe data from twrp data you have stored on your internal sdcard gets wiped and after reboot needs to be replaced to maintain your second safety net.

I installed version 4.2 on my asus JB tf300t.

I lost the root and when starting in recovery mode, I get this message starting fastboot USB download protocol.

I can not rooting, since I no usb icon appears.

Some would guide me back to rooting and how I can put the TWRP
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
Actually when you get the message starting fastboot you are ready to give the fastboot commands as if you had selected the usb icon. This is one of the changes in 4.2 the bootloader menu.

Hi dudes..

I have a new Transformer tf300 :) Its a good tablet, but I find no option to move my apps to external sd card!? I have only the 16GB version and I thought its no problem.....At my tablet its all original, stock rom, no root....and I will not change that, cause its very new ;)

There are any options, without custom rom??
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
I have never tried app2sd so I can't speak from experience. I looked on google play and there seem to be many choices.

In the past I had heard many horror stories when an update is received but that is history now.

If possible I would put my pics, docs, music, and other data on the external sdcard and try to avoid moving the apps.

Note: I have over 100 apps on my tf300 and the same on my 16gig android tablet and have never had an issue with space. Apps are in general small in size and data is larger. You can have a huge number of apps in 16gig.

Doing everything this way if I have a failure I loose the data which is also located on my pc so I just have to copy from pc to new external sdcard and I'm back to normal.

Note: Asus updates require the standard Asus software to be intact or fail to install. On the surface that is fine but when you take a play store update for Asus software it is now available for most app2sd apps and if moved your next ota may fail. If you decide to use app2sd consider leaving anything that relates to Asus alone.

Good Luck!

Hardware curiosity

Hi,

I've seen some mentioning of the Champagne Gold version (serial no's from C9 upwards) being somewhat different (were delivered with JB).

Mine is the new Black version (with dock) and my serial starts with D2. (Yes, it came probably with the 10.4.2.20 and updated instantly to 10.6.1.8 FW).

Is there any significance of the serial numbers? Or do I only need to focus on being compatible with the 10.6.1.8 FW if I go for a ROM?

Are there any other differences?
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
I have not seen that designation in the past.

Serial prefixes in the past denoted sku (country designations).

Some serials have failed to allow unlocking and had to be placed in the Asus database.

Beyond that yes ensure anything you flash has the new 4.2 bootloader or you may have a brick.

There is a new twrp for 4.2 and is designated as such on the teamwin.com site, ensure you use it as long as you are on the new bootloader.

There have been many bricks for failure to use the proper recovery and rom.

Good Luck!
[Transformer TF300T Q&A, Help & Troubleshooting] Rhian:
Thanks, it must be the specific C9's I've read about.

I do have the patched TWRP 2.4.4.0 from the forum here, although I didn't try the one on http://www.teamw.in

As for the ROM, it's still stock, I'm being very careful.
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
The twrp you have is fine. It was a quick fix and later teamwin posted a release on their site. I believe they are now the same.

One note: Because a rom says 4.2 does not make it safe to flash over stock 4.2. Some of the 4.2 roms came out before the official Asus release and use the wrong bootloader. Look carefully that it is based on stock 4.2 or is compatible with the 4.2 bootloader.
[Transformer TF300T Q&A, Help & Troubleshooting] g_money:
It's my understanding that this is an issue with google play apps or the latest android update? From what I hear, you have to be root to be able to move apps to your ext sd. Twried a bunch of apps, none worked...

Hi all

My tf300t is on Jellybin 4.1.1, i'm trying since a lot of time to get android out but i still have many problems.

First, the official unlocker from asus is ****ed up, i know taht some other people here got the same problem

Secondly, i've see some days ago that ASUS has give a new one, but only for 4.2... tryed it, doasnt work. So i try to get up to 4.2, with the offical maj, doasnt work. Try to force the maj, nothing more.

So i started to get on adb, and after lauching fastboot the next instruction in the noobproof guide ( http://xdaforums.com/showthread.php?t=1845377 ) is to lauche fastboot HEXA-- flash recovery something.blob if i remmember. 2 possibilities are given, the TWRP and the CWM.

Tryed both, still get the same < waiting for device > in my term, and ofc no blue bar on my tf300t ^^

So, wath do you think i should do, or wath do you think i should read ?

Ho, o i did'nt do the part I and II of the noobprof guide, beaucause i'm allready on jealybin i did'nt thought that wath nessesary.

And even one more : I'm french, so excuse my bad english ;)
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
Your English is much better than my French (none).

Since you are not unlocked you can't use fastboot or flash a custom recovery (CWM and Twrp). When you are unlocked I suggest Twrp.

I don't suggest the new firmware 4.2 (10.6.1.8) at this moment. There are many bricks waiting for resolution.

If you must; download it, unzip once and name the resulting zip EP201_768_SDUPDATE.zip. Copy to your internal sdcard and wait for triangle update notification. If you don't get notification in a couple of minutes reboot and wait again.

If it still fails power off. Power on holding power and volume down. When you get the bootloader menu press volume up and stock recovery should take over and in about ten minutes you should be updated.

I can't help with the unlocking problem as there seems to an issue with Asus database of serial numbers. Contact them and hope you get someone who wants to help.
[Transformer TF300T Q&A, Help & Troubleshooting] Rhian:
Strange, my TF300T did recognise the default ASUS naming WW_epad-user-10.6.1.8.zip (from the original TF300T-WW_epad-user-10_6_1_8UpdateLauncher.zip ) without any issues. Likewise with the 10.4.2.20 for downgrading.

(Yes, indeed, up/down-grading without unlocking. Pity my model is very new (black, possibly HW like the champagne version) and keeps dropping out its WiFi connection when running anything based on the 10.4.2.20. So I'm stuck with 10.6.1.8, which makes me wonder what in-between version it shipped with.

@LNRV:

You could try:

1) a factory reset and test the unlock_v7.apk on your current version

or

2) download and try the 'upgrade' to 10.4.2.20 and then try the unlock_v7.apk if you want to stay on your current version. (Useful if you want to run other roms). Please do make sure you have the correct SKU (like WW if it says that in About Tablet > Build Number).

Alternatively, you can upgrade using the outlined steps.

New to Tablet World

Hey all,

First off I'd like to say thanks for this thread and all of the hard work you all put in so we can get the best of our devices.

I just received my TF300T that I purchased from swappa. It has TWRP 2.4.4., unlocked bootloader, and is currently running CM10.1 nightlies.

After looking over some of the ROMS, I am a bit confused with the whole bootloader thing, what I have, and what ROMS I can flash without getting into trouble and can just download and flash through TWRP.

I'd really like to try out JellyBean-Hydro 7, but again confused with - "to clarify this is if you have ota jellybean bootloaders already only..or some form of stock asus Jelly bean bootloader no cm10 aokp aosp paranoid etc..anything not ota doesnt count as jb bootloader or already running jb"

How can I determine what bootloader I have if it's running CM10.1 Nighlies? Trying not to get ahead of myself, and appreciate the help in advance.

Thanks again for all the hard work! I have plenty of time to continue reading. This is my b-day present, and wife said I can't use it till then (end of next month :crying:)
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
I just looked at the Hydro 7 thread and you have to be on an Asus stock JB rom (4.1) - (not-4.2) to flash Hydro safely. It is based on 10.4.2.20. If I were going to use Hydro 7 I would use twrp to flash Asus stock 10.4.2.20. You will loose twrp and have stock recovery instead. Just reflash twrp with fastboot and follow the directions in Hydro 7 and you should be good.

Note: The new Asus 4.2 JB 10.6.1.8 is a third bootloader to consider before you flash a rom or recovery.

At this time to run CM10.1 you are on the Asus JB (4.1) bootloader. I know the thread says 4.2 but that is not declaring 4.2 bootloader. I know this is confusing but Asus has seen fit to make our lives more complex.

Good Luck!
[Transformer TF300T Q&A, Help & Troubleshooting] Dhickory:
Awesome thanks! Been doing some good reading and feel pretty confident in updating to newer firmware.

If I do a nandroid backup of my current CM10.1, then load either 10.4.2.20 or 10.6.1.8, will I be able to restore my backup of CM10.1 at a later time, or not since it is for 4.1 bootloader?

Thanks again for you help!
[Transformer TF300T Q&A, Help & Troubleshooting] tobdaryl:
This is a sticky situation because you asked about two different bootloaders.

In answer to your question about restoring CM10.1 the answer is yes from 10.4.2.20 because they use the same bootloader.

If you have 10.6.1.8 on your tablet then no because the bootloader is different. At the moment the only safe way(I will suggest-and yes I have seen other methods) to go to and from 10.6.1.8 is with 10.4.2.20 and stock recovery.

In the future CM10.1 will probably change but the current version uses Asus 4.1 bootloader not the new Asus 4.2 bootloader.

Confusing? Yes!

You have to keep abreast of changes and make your decisions based on the situation at that time.

To help someone else I made my fifth move between the two JB bootloaders(4.1 and 4.2) yesterday. It went without a problem but of course I used 10.4.2.20 and stock recovery as my vehicle.

While the tablet is in CWM type

adb reboot-bootloader
[Transformer TF300T Q&A, Help & Troubleshooting] Rhian:
FW for android 4.2.1 does change the way the filesystem works. You need to get the TWRP for this FW.

I'm sure you can get it to fastboot. Turn off. Hold Volume-Down + Power, wait for the bootloader to come up (you are on 4.2, so no USB icon), STOP!

Don't touch your pad, just plug the USB cable into your PC, then you can check connectivity "fastboot devices".

If it only goes straight into CWM, then while connected use "adb reboot-bootloader"

You can only install TWRP through:

"fastboot -i 0x0b05 flash recovery <your twrp blob>"

Please see this thread:

[GUIDE] Update/Recovery/Root/Downgrade Android 4.2.1 on Unlocked/Locked Devices

Look for the section: [UNLOCKED BL]-- Installing TWRP (Recovery) --

Download the file and follow the instructions.

The file does contain adb, fastboot and TWRP. So all you need is there, except for the drivers.

CMW is AFAIK not yet JB 4.2.1 FW ready. If it is by now, feel free to search the forum.

Good luck!
[Transformer TF300T Q&A, Help & Troubleshooting] EndlessDissent:
Why can't he use ADB to install TWRP if that's what he has access to?

From the TWRP website:

So, if he can access ADB, the commands would be:

adb shell
su
dd if=/path/to/twrp.blob of=/dev/block/mmcblk0p4
reboot recovery

I would like to say, however, if you can get into fastboot, that's a lot safer than using ADB to flash a recovery -- less chance of a catastrophic typo bricking your tablet. But, if ADB is what you have to work with, work with it.
[Transformer TF300T Q&A, Help & Troubleshooting] Rhian:
If you read the post, he was stuck in an old CWM, giving I/O errors.

I guess the risk on typonese with dd command is a lot higher than using fastboot. The problem stated was that he was stuck in an old CMW, thus no access to the filesystem (see the errors in the original post). So dd will fail and might even make matters worse, so that's why I didn't suggest flashing with adb at all.

Since he's already on 4.2.1, the fastboot bootloader is already available before going into recovery, unlike the 4.1 where the USB icon needed to be accessed.

Also another quick note - make sure you choose the right blob for TWRP (there are ICS, JB, and now 42 variants). Currently the 42 variant is not working (at least not for me, but I can't post in the other forum because of my <10 posts restriction). I'm getting a weird double screen issue that I'm sure will be fixed soon if it hasn't been done already.

Energy is now truly based on the 4.2 stock rom. I don't care for 4.2 but since we appear to have a mix of 4.1 and 4.2 I suggest you unzip the stock asus 4.2 (10.6.1.8) firmware twice. put the blob in the directory with fastboot and flash.

fastboot -i 0x0B05 flash system update.blob

fastboot -i 0x0B05 reboot
