What Works/Doesn't Work
What Works:
Almost everything!
What Doesn't Work:
Changing Brightness Settings without the use of a Third-Party App
Resolution (DPI is set to 160 by default and changing it through an App or directly with build.prop makes no changes) - FIXED
You WILL lose Root and Custom Recovery with these methods
Drivers
I used the ASUS Android USB Drivers from the following post for ABD/Fastboot: http://forum.xda-developers.com/showthread.php?t=1706588
Installation
Method 1 for Locked/Unlocked Bootloader with Stock Recovery and/or Root
1. Power off your tablet
2. Download the latest TF300T firmware (XX_epaduser_10_4_2_9_UpdateLauncher.zip) from Asus site based on your SKU location (eg. ww, US, etc): http://support.asus.com/Download.aspx?SLanguage=en&m=ASUS Transformer Pad TF300T&p=20&s=16
3. Right click and extract the downloaded .ZIP file (XX_epaduser_10_4_2_9_UpdateLauncher.zip) onto your desktop
4. Rename the extracted .ZIP to "EP201_768_SDUPDATE" (without the " ") and copy it to your MicroSD card
5. Insert the MicroSD card in your tablet
6. Boot your tablet into Recovery by pressing and holding Volume Down AND Power for 5 seconds
7. A message will inform you that you have 5 seconds to enter Recovery; press Volume Up before the 5 seconds expire
8. At this point the device will go in recovery and should start updating your firmware
Method 2 for Unlocked Bootloader with Custom Recovery and/or Root
1. Power off your tablet
2. Download the latest TF300T firmware (XX_epaduser_10_4_2_9_UpdateLauncher.zip) from Asus site based on your SKU location (eg. ww, US, etc): http://support.asus.com/Download.aspx?SLanguage=en&m=ASUS Transformer Pad TF300T&p=20&s=16
3. Right click and extract the downloaded .ZIP file (XX_epaduser_10_4_2_9_UpdateLauncher.zip) onto your desktop
4. Copy the extracted .ZIP (XX_epad-user-10.4.2.9.zip) to your MicroSD card
5. Insert the MicroSD card in your tablet
6. Boot your tablet into Recovery by pressing and holding Volume Down AND Power for 5 seconds
7. A message will inform you that you have 5 seconds to enter Recovery; press Volume Up before the 5 seconds expire
8. From your recovery menu press Install and select the .ZIP file (XX_epad-user-10.4.2.9.zip)
9. Wait until the install process ends and then restart your device
Method 3 Advanced using Fastboot
1. Power off your tablet
2. Download the latest TF300T firmware (XX_epaduser_10_4_2_9_UpdateLauncher.zip) from Asus site based on your SKU location (eg. ww, US, etc): http://support.asus.com/Download.aspx?SLanguage=en&m=ASUS Transformer Pad TF300T&p=20&s=16
3. Right click and extract the downloaded .ZIP file (XX_epaduser_10_4_2_9_UpdateLauncher.zip) onto your desktop
4. Right click and extract the new .ZIP file (XX_epad-user-10.4.2.9.zip) onto your desktop; you should now have the blob binary and META-INF folder on your desktop
5. Copy the blob binary to your platform-tools folder (C:\Program Files\Android\android-sdk\platform-tools or C:\Program Files (x86)\Android\android-sdk\platform-tools)
6. Plug tablet into your computer
7. Boot your tablet into Fastboot by pressing and holding Volume Down AND Power for 5 seconds
8. A message will inform you that you have 5 seconds to enter Recovery; press Volume Down twice to select Fastboot and then Volume Up before the 5 seconds expire
9. Open a command prompt and cd into your platform-tools folder; or press right-Shift on your keyboard and right-click the platform-tools folder and click "Open command window here"
10. Enter the following command in the command prompt: "fastboot -i 0x0B05 flash system blob" (without the " ")
11. Once the previous command completes enter: "fastboot -i 0x0B05 reboot" (without the " ")
RECOMMENDED but Optional Steps:
If you are using Stock Recovery it is advised to Factory Data Reset or Wipe Data both BEFORE and AFTER the Firmware Upgrade
If you are using Custom Recovery it is advised to wipe ALL partitions
Unlocking the Bootloader
You can use the ASUS Unlock Tool from the ASUS Support site to unlock your bootloader. Despite ASUS saying it's for ICS it works fine on JB. Detailed instructions to come.
Recovery (TWRP) **Requires Unlocked Bootloader**
1. Turn your tablet off
2. Download the latest TWRP blob: http://teamw.in/project/twrp2/105
3. Rename the blob binary (openrecovery-twrp-X.X.X.X-tf700t.blob) to "twrp.blob" (without the " ")
4. Copy the twrp.blob binary to your platform-tools folder (C:\Program Files\Android\android-sdk\platform-tools or C:\Program Files (x86)\Android\android-sdk\platform-tools)
5. Plug tablet into your computer
6. Boot your tablet into Fastboot by pressing and holding Volume Down AND Power for 5 seconds
7. A message will inform you that you have 5 seconds to enter Recovery; press Volume Down twice to select Fastboot and then Volume Up before the 5 seconds expire
8. Open a command prompt and cd into your platform-tools folder; or press right-Shift on your keyboard and right-click the platform-tools folder and click "Open command window here"
9. Enter the following command in the command prompt: "fastboot -i 0x0B05 flash recovery twrp.blob" (without the " ")
10. Once the previous command completes enter: "fastboot -i 0x0B05 reboot" (without the " ")
Root **Requires Unlocked Bootloader AND Custom Recovery**
1. Download the latest Custom Recovery installable SuperSU .ZIP (CWM-SuperSU-vX.XX.zip): http://forum.xda-developers.com/showthread.php?t=1538053
2. Plug tablet into your computer
3. Copy the SuperSU .ZIP (CWM-SuperSU-vX.XX.zip) to Internal Storage
4. Turn your tablet off
5. Boot your tablet into Recovery by pressing and holding Volume Down AND Power for 5 seconds
6. A message will inform you that you have 5 seconds to enter Recovery; press Volume Up before the 5 seconds expire
7. From your recovery menu press Install and select the SuperSU .ZIP (CWM-SuperSU-vX.XX.zip)
8. Wait until the install process ends and then restart your device
9. Now your tablet should be rooted

F.A.Q.
JB seems to be laggy. Any suggestions?
Yes, Wipe!! Even if you've performed a Factory Data Reset or Wipe Data I HIGHLY recommend unlocking your bootloader, installing a Custom Recovery, wiping EVERYTHING and installing the firmware again; preferably using Method 3.
Is there any way to change the Brightness settings?
Yes, through Third Party Apps. The most popular seem to be Lux and Custom Brightness Settings
Are we "SOL" having the TF300 Bootloader when the Tf700 JB Firmware comes out?
Personally I'm not too worried about the bootloader.
Either the official JB for TF700 will have the same bootloader as for the TF300, or it will be a newer version that we'll be able to flash.
The bootloader doesn't seem to be looking for a device check or else the 300 loader wouldn't have installed on the 700.
It really only seems to be doing a sig check for OLDER firmwares, not NEWER.
Why don't we have an Official TF700 JB Firmware yet?
I don't know, ask ASUS. I'm as flabbergasted as you are. We've only found two issues so far!!

UPDATE UPDATE: Kernel configs are also amazingly identical. Most new options available in the JB 3.X kernel aren't even set. Only things that stick out are that CONFIG_SENSORS_ISL29028 (Light Sensor driver) went from yes to not set. Also I keep seeing NFC code EVERYWHERE which is disabled in JB stuff. Does the TF700 have NFC or is ASUS pulling from one base? <-(Hmmm...) CONFIG_NTFS_FS has also been set to yes in JB so we should check out NTFS formatted SDCARDs. Also fun fact; CONFIG_ISO9660_FS (CD/DVD Filesystems) was set to yes in the ICS kernel. LOL. Everything we need is there, somethings just stopping it. It's funny looking through the code you can tell it was written by two different teams as most times configs contain the same info, only in a different order. Makes it hard to compare code though; jerks. No wonder it's not officially out yet.
UPDATE: I just finished comparing /system between the TF300 JB blob and the TF700 ICS blob. 98% of the config files are similar or are only off by a line or two. Issues with screen resolution and brightness seem to be stemming from kernel. I'm gonna see if I can rip the ICS kernel out and transplant it in JB or recompile the TF300 kernel using the config from ICS. They jumped from 2.6.X to 3.X so who knows...

Is there a reason you need to name it recovery.zip? I just named it 300jb.zip, been installing for almost 30 mins here!
Unlocked bootloader, custom recovery and complete wipe.

Nope, just going off what most people named it.

To get root back, its failrly easy.
1. Install TWRP using fastboot. Just check their site for the how to do. Make sure you have fastboot and the drivers on your PC
2. Download SuperSU-CWM pack from the SuperSU topic on XDA.
3. put the SuperSU pack on your SDcard internal or external.
4. Flash that pack.
5. Boot up and open up SuperSU.
6. Update binary and done
Maybe nice to note what is broke if you use this flashing methode.
- Brightness controll is broken. Its on full all the time
- Everything is a little bigger then usual, Or I am a little blind
For the rest I added the tweaks to the build.prob from the tips topic and I am running super smooth.
And I just downloaded that update for the TF300 from the asus site. Extracted it so I got the update zip thingy. Placed that on my SDcard. Wiped all and just installed. Did not rename a thing. And it worked just fine.
Then I did the steps from above and thats it.
Rooted and unlocked with TWRP running JB Me is very happy

Has anyone tested if the lag still exists with a bluetooth headset while viewing a video?

anyone know what causes a data transfer failure with the error "too many links" when using fastboot to flash?
i was able to get the boot blob to flash, but when i try flashing the system blob it crashes with that error. btw i'm flashing things separately because i don't want to have my bootloader updated.

Actually I didn't, or I wouldn't have asked it. If the answer is "you can't flash this system blob with the old bootloader", then saying so would be an appropriate response.
Also, since it could be caused by something else like an inability of fastboot to flash extracted system blobs without the header file, or maybe corruption in the blob caused by using a windows binary of blobunpack, I feel my question is quite valid.
edit: I ended up doing more research and it appears that even if I did get the system blob flashed, it probably wouldn't boot without the updated bootloader due to the 3.x kernel. Even the custom JB roms for the 300 make you update the bootloader on that tablet first.
So, I'm going to put this on the backburner until there's an official bootloader update for the 700 or until someone already on the new 300 bootloader successfully flashes back to the current one.

I added the build.props tweaks and it bricked my tablet at ASUS bootsplash? which ones did you add? can you upload your build.prop?

I would much prefer it if we could install a custom ROM from our bros over at the TF300 forums.
Do those work as well or is it just the ASUS stock stuff?

I'm pretty sure you need to be on the new bootloader for the stock rom / stock-based roms to work. I've been reading through the tf300 forums and so far I haven't found any posts about anyone being able to revert back to the ICS bootloader. One guy suggested this is due to signature checking, different permissions, and possibly an altogether different partition table.

AFAIK, the bootloader can't alter the partition table on Tegra units. In fact, the bootloader is itself a partition. Only way to change the partition table is with nvflash.

Hopefully the TF700 JB Update would be able to flash over the TF300 JB Bootloader, otherwise we will stuck at this "not so perfect"-build for a very long time!
I miss the DPI changing I'm not blind and everything is so ****ing big on the screen.
Guys, did someone else see that the Battery is going low pretty much faster?

If you change the updater-script (attached in zip) with the one in this ROM: http://forum.xda-developers.com/showthread.php?t=1854212
in the subfolder: Asu-JellyBean-HyDRO-R1.zip\META-INF\com\google\android\
You can Install it on your TF700T
I'm running it right now, but I will go back to stock JB because ASUS Settings bring a force close.
All other things are still the same, backlight doesn't work, anything else is fine.

Hopefully someone sees something helpful from this and can make a safe stock tf700 update.
Seems devs here work as hard as asus does.
Thanks guys for all you do

Return to stock recovery.

Hi guys, I have a seriosly problem.
I have rooted y TF300T with 1.1 clik transformer root.
The root is ok but now I want return to full stock firmware.
I follow this:
Step #1: Download the stock ROM zip file from here [Official site], download file that is match to your SKU.
Step #2: Unzip the file you’ve downloaded, it will give you another archive called, unzip that file too. You’ll end up with many files including blob.
Step #3: Turn the tablet off.
Step #4: Reboot the device by holding down volume down and power button until you see a message saying “Press Vol. Up to enter RCK (5s)”, but you don’t press the volume up button, just wait until a menu appear on the device, then within 10 second press the volume down button once to navigate on USB icon, then press the volume up button to select and connect it to the PC using USB cable.
Step #4: Open command prompt and go to a folder where you’ve blob file that you got in step 2.
Step #5: Enter following command:
fastboot -i 0x0B05 flash system blob
Do note that, the transfer seems to fail from time to time, if it happens, try again by going back to this step.
Step #6: After transfer, when you’ve got “SUCCESS” message, enter another following command to reboot device:
fastboot -i 0x0B05 reboot
That’s it, you’re now on stock firmware. Don’t forget to comment below, you can also visit the original thread of XDA here to thanks the developer for this great effort.
but when i go on step 4 i have this screen with only this optnion (no usb connection)
so it's impossible restore the firmware.
Please, anywhere help me.
Sorry for my english.
I returned to stock using a recovery manager, you flash the stock zip in that.

Can You explain better the procedure.
Thanks.
search for wolfs ultimate guide on how to change firmware. it has instructions for changing firmware or just reinstalling current if rooted or not. but remember to read it carefully. get the blob files from Asus website for the tf300. that's how I did mine

Did you only root? or did you unlock bootloader/flash custom rom or whatever?
If only root, can you not just use 1-Click Transformer Root to unroot again? :/
Are you only rooted? did you unlock your pad? im kinda curious here - you state you want stock recovery back - may i ask why?
if you only want recovery back use the recovery.ig from the stock firmware and do a "fastboot flash recovery recovery.img"
but i'm not quite sure what your intend here really is to be honest. From the commands you were intending to use it sounds more like a stock rom flash (which you can do from inside cwm/twrp2 as well reboot and you are back to pure stock after a reboot without the use of adb/fastboot shell
please clarify
cheers
In OP he said he wanted to get back to stock rom. You can either do this via CWM/TWRP or by fastbooting. But it looks like you can't enter USB mode, right?

[Q] How to unbrick my tf300

Hi there, Can anyone help me to unrick my tf300, its stuck on the logo screen.
I have try many things, some guys from hong kong tell me i have to use APX mode to sort the problems out, I manage so far.
Drivers I download the is Universal_Naked_Driver_0.7, also use nvflash drivers, both I try. i still get te samethings when I try to use the nvflash
I turn on tf300 with volume up, few seconds the screen went blank, and hear a beep from my pc, so is connect alright.
I type download.bat command, with prime 1.4 rom in the same folder. after few seconds I get
nvflash start
unknow usb found.
Can anyone tell me what i done wrong here.
can someone show me some step by step.
otherwise is a waste of money, the tf300 not working.

You flashed a PRIME rom to your tf300?
First of all, we should know which firmware do you have before your tablet doesn't boot (Stock ICS, JB, Custom Rom).
Then, you can use fastboot to recover your tablet (i did it a lot of times). Try steps below:
1. Download latest oficial Asus firmware (V10.4.2.13). BE SURE to download your region (WW, US, etc...)
2. Extract downloaded zip and take blob file.
3. Download Android SDK and install them on C:\ (http://developer.android.com/sdk/index.html)
4. Execute SDK downloader and mark tools and platform-tool options for download.
5. OPTIONAL add tools and platform-tool folder to PATH, after that test if fastboot command runs on CMD.
6 Copy blob file on same SDK folder.
7. Connect TF300T with usb cable and put it in Download Mode (USB icon on recovery menu)
8. Wait until drivers are installed.
7. Open CMD, go to Android SDK folder and then type command below:
fastboot -i 0x0B05 flash system blob
wait 2 or 3 minutes and then you'll see a message that send and write was OK. Now type this command:
fastboot -i 0x0B05 reboot
And It should boot again.

Yes, that's right, but I suppost if he tries to flash a custom rom he has already unlocked his device. You can't flash any rom without unlock bootloader.
I cant do anything apart from get on to apx mode, from apx mode how do I use command to flash back.
My tf300 is ics, unlock.
when i connect usb to pc. i press power and volume up. thats only things i can do.
so what do i do next?
thanks.
The same problem.
I only see: "device is unlocked" or something like that. And nothing go on.
Is it totaly bicked or is there any chance to restore it?
Please advice.
Did anybody ever figure this out. I'm in the same boat. Can't do vol down+power to get to recovery. But if i do volume up+power it shows in device manager as transformer prime apx interface (even though it's just a tf300)

no way to unbrick tf300t
Funny, I bricked my tf300t without doing anything. One day it just got stuck in asus screen.
tried to recover, nothing happended.
tried hard reset. Nothing.
Wipe data: result: bricked tablet.
I'm looking for information it is defintely impossible to unbrick it.
Anybody else with the same situation can tell you that.
Nobody has even been able to do it.
If you send it to Asus they provide a new tablet.
Conclusion:
TF300T is a terrible product, as any other asus product i assume. Amazing that you can brick a tablet without even trying to flash it or without even being connected to a computer.
It bricks by itself. Hundreds of other users can confirm it.
My advice: dont by asus products
If you already have one, dont use wipe data as anybody who has done it has ended up with an expensive useless brick.
Odp: [Q] How to unbrick my tf300
I don't agree witch this, only think what you not should use is t the wipe data from bootloader menu - I already flashed many times not working kernel, get really often bootloop - the problem is - much users going to made stupid things when the get a soft bootloop - If you get this first try wipe data from recovery, if this won't help, try to format data from recovery - often happends that the ext4 filessystem get broken. Recovery should allowa us to run fsck on data - I fixed my bootloops many times with it without loosing my data.

OP,
I think your anger is misdirected. The device, as it comes out of the box, works 100% without issues. YOU as a user decided to make changes that could potentially brick it. YOU chose to follow the steps with the full disclaimer that it can/may brick your device. So at the end of the day, its' not the fault of ASUS or the device for "bricking itself"; the responsibility of your actions lies on your own shoulders.
That being said, Asus will not provide warranty support for a tablet that has been unlocked. This is clearly stated in their unlocker app. So no, they won't "send you a new tablet" if you send it to them (unless you pay out of pocket for the repairs).
I've done just about as bad of a brick as I possibly can on my tablet and recovered just fine. It was just a matter of being CAREFUL, reading instructions three times before l followed them, and asking lots of questions. But what ultimately saved me was the NVFlash tool, and for that I am eternally grateful.
Just my two cents.

I have problem that my partitions won't mount at all. I have access to fastboot, CWM, and adb but no matter what i cannot access my partitions and so i cannot install zip from CWM. When i try blob within fastboot my tablet just freezes.....
Hi, what happens if I have no access to fastboot? It loops in the ASUS logo and what ever I do, can't gain access to recovery because it doesn't get into fastboot. So how to solve it via APX? Thank you.
You wont solve the problem unless youve done a nvflash backup. If you tablet is recognised as APX while plugged in PC, then you have an unrecoverable brick. If nothing appears when you plug it, then try on another PC.

Hi,
I am having a similar problem to the one described. I have unvblocked my TF300T and installed CWM recovery (v. 6.0.2.3), but it can't mount any filesystem, so I can not flash anything. The boot menu is gone (RCK, wipe tablet, android) and when I switch the tablet on It just goes to CWM. If I connect the tablet to a PC, I can send commands with adb from my win 7 PC (for instance "adb reboot" will reboot the tablet), but fastboot doesn't work (it keeps "waiting for device"). Prior to this my android version was JB 4.2. I didn't make any backup, so I am fearing the worst outcome. Did I brick my tablet for good?
Thanks a lot for any reply.
TF300T blocked on boot screen
hello everybody,
my name is jonathan, and i have a very big problem.
My Asus TF300t is blocked on boot screen after try to install a new rom on JB 4.2.2.
>My clockworkMod reconvery is v6.0.1.0.
I tried to install several roms, offical or not but the problem is the same, "The device is unlocked" on the boot screen Asus...
I read the previously posts and :
- i installed on my pc the sdk
- i dowload the "blob" file and i placed it on tools directory
- but, the actually problem is whis the lign "fastboot -i OxOBO5.... (i have copied and paste it on schell command) and enter
load_file: could not allocate 820157833 bytes
error: cannot load "blob": not enough space
can you help me please ?
i want to resolve this problem with you to install the best rom for this model.
Thank you very much and sorry for my english, i am french but i understand your paragraph.
See you soon
Jonathan
If you have mounting / PIT errors you could try my solution as described here:
http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
no guarantee though but it basically wipes your device so that you should be able to flash the blob file back.
also if your tab still is ICS- check if you are using the correct recovery - also bear in mind that cm10.1 afaik uses the new 4.2 bootloader and probably wont work with ics based PIT devices.

same problem of space

Hello man,
I try your method but the problem is the same when i want to copy the blob file, "not enough space ..."
fastboot erase system OK
fastboot erase recovery OK
fastboot erase userdata OK
fastboot erase boot OK
fastboot erase misc OK
fastboot erase cache OK
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob PROBLEM
The message is the same like previously, always the problem of space.
I tries the method by copy the blob file on different directory on my computer and on a usb key too.
Always the same problem of space
I think the problem is the space on the tablet but i dont' understand. I erase system, recovery, userdata, boot, misc, cache, i think the tablet is empty.
Can you help me please ?
Thank you very much
Jonathan
which blob file did you use? Was the zip appropriate for your region? also what was the last stock rom version you ran - you said you wanted to update to 4.2.2 - what was the old version?

[Q] Custom ROM on TF300T

HI all,
I am VERY new to this custom ROM stuff, and I am a bit confused. I have an ASUS TF300T Transformer Tablet. It has 4.2.1 loaded, build is JOP40D.US_epad-10.6.1.12.3-20130416. If more particulars are needed, I can provide.
I have rooted the tablet (I used motochopper to gain superuser access), thinking that would allow me to load a custom ROM. I was WRONG (as most of you probably know). I want to load a custom ROM (CyanogenMod), and also not use the ASUS preloaded software. I want something with less bloat, is faster, and something I can customize at will.
So....I have read a ton of posts on this, but I can't seem to find a step by step single, simple process to accomplish this daunting task. Simply put, I need step by step instructions that can get me where I want to be. At this point, I'm not so sure I could be more confused! LOL!
Anyone who has done this, or is experienced with this, I could use some major league assistance!
I want a faster, more "open" tablet. I also know I don't want to brick it. I definitely don't need a 300.00 paperweight!
Any help would be greatly appreciated.
Thanks!!
Scar!

You need a custom recovery! download twrp here: http://techerrata.com/browse/twrp2/tf300t
DOWNLOAD THE ONE THAT SAYS "openrecovery-twrp-2.5.0.0-4.2" and flash it with fastboot in cmd " fastboot -i 0x0B05 flash recovery twrp.blob" make sure you rename the blob to "twrp.blob"
*update your info your bootloader is "10.6.1.15.3" instead of "10.6.1.12.3"
Sent from my ASUS Transformer Pad TF300T using xda app-developers app
You can also follow this guide. It explains what you need to do pretty well. But you do need a custom recovery, which i prefer TWRP http://forum.xda-developers.com/showthread.php?t=2187982
I was confused at first too. I think they need to change the wording in the tutorials. They say "If you're on JB bootloader, this twrp, if you're on 4.2 BL, that TWRP" and i was just thinking... WTF, both of them, 4.1 and 4.2 are jellybean.... it should be changed to 4.1 BL and 4.2 BL, none referred to as JB.

So...does my tablet need to be unlocked first? What do I do once TWRP is loaded on my tablet? When you say "flash it with fastboot in cmd " fastboot -i 0x0B05 flash recovery twrp.blob". What does this mean? This is where it gets very confusing.

if you installed root on your device you should have adb and fastboot, right?
if you are on windows(pc) press the windows key + the R key and type cmd in the search box, then press enter now navigate to the adb/fastboot directory on your pc by typing "cd <the location of the file>" then plug in your tablet in fastboot and type " fastboot -i 0x0B05 flash recovery twrp.blob" what does this do? this command flashes twrp over the stock recovery, with twrp you can install custom roms! after you have done this download a rom you like (watch out for bootloader versions! if you are on stock 4.2.1 i would reccomend the latest unofficial AOKP or the latest official cm10.1) if you download a rom you can see it is a zip file, place this zip file on your sdcard and power up your tablet in bootloader by holding volume down + power button till icons pop up! now press the volume up key when the RCK icon is blinking! now twrp should start, now click on wipe and then advanced wipe and wipe system data cache(you don't need to wipe your data if you prefer to keep it!) now go back to the main menu of twrp by pressing the home button in the top right corner, now click install and navigate to the directory you have placed the rom in, after install reboot!
I've a TF300TG but I think my question is associated to the title of this thread. Do I have to note the sku of my Pad or isn't that important when I flash a custom Rom?
In the threads of many custom Roms I've read nothing about the sku. So I'm not sure if I have to take care for this.

OK, first, I am on a MAC. I have "terminal" for CMD lines, so, it should find whatever files I need it to find just as the windows CMD block will.
I have "fastboot and ADB" in a folder on my desktop, I have named the folder "android". I also downloaded the TWRP for 4.2.1 (renamed to TWRP.BLOB). I think I have all the files I require, it's just a matter of what steps to take. I also have the CM 10.1. This is the ROM I would like to use.
I was also reading that using TWRP, I am not supposed to wipe. I guess, theoretically, I want to be able to boot to the original ASUS ROM in case anything goes wrong. Otherwise, I wouldn't have a ROM to boot from.
I'm not sure if everything I am saying is correct, again, I am very new to this and trying to undertand exactly what I am doing.

I can TRY to help. I have no mac, never used one, dont know the procedures for getting the drivers and stuff installed on mac. So, im going to assume you have the fastboot drivers installed properly.
NOTE: IF YOU'RE TABLET BREAKS, NEVER TURNS ON AGAIN, OR GOES UP IN SMOKE BECAUSE OF MY DIRECTIONS, IT'S ALL YOUR FAULT AND RESPONSIBILITY NOT MINE. GET OVER IT AND BUY A NEW ONE.....LMAO.... really though, i am helping as best as i can and you always run a risk flashing devices and thats your risk, not mine.... but if you follow my directions exactly, you will be jsut fine and not have a broken device...
First, make sure you're on the latest update from asus. Should be a bootloader ending in 15.3 and android 4.2.1 .
Second, unlock your bootloader. Unlocking the bootloader is quite simple. Download this: http://d-h.st/86c Install it on the tablet and open the app (its a RAR file so it needs extracted first) Follow the directions it gives you, if i remember correctly, you just click yes or something, tablet reboots, and the bootloaders unlocked. If it sucessfully unlocks, when you first turn the tablet on, in the top left corner of the screen, it will say unlocked.
After bootloaders unlocked, turn the tablet off. Power on the tablet by holding the power button and the volume down button at the same time. This will take you into bootloader mode. One quick thing to make sure you are on the latest bootloader. The bootloader screen should have 3 icons to choose from, if it has 4, you are on the old/wrong bootloader and need to go back and update your system before proceeding. If 3 icons, you're good to go, plug the usb cable in the tablet and in your computer.
Download TWRP recovery now. This is the part where you dont wanna screw up, downloading and flashing wrong recovery can equal a broken tablet. Download this exact TWRP recovery: http://diesburg.co/tf300t/twrp/openrecovery-twrp-2.5.0.0-tf300t-4.2.blob
Put that file in the folder where fastboot is.
Now in your terminal/command line, go to the directory where fastboot is. With tablet plugged in and in bootloader mode like mentioned above and terminal in the fastboot folder, type: fastboot -i 0x0B05 flash recovery openrecovery-twrp-2.5.0.0-tf300t-4.2.blob and press enter .... this will flash TWRP recovery to your tablet using fastboot.... if you get something like "waiting for device" in your terminal window after typing this and it never gets past that, thats where i cant help, drivers for fastboot or something isnt right.... if it works, hell yea, onto the next step....
Reboot the tablet, type: fastboot -i 0x0B05 reboot and press enter.... let android fully boot up, copy your ROM to your tablet and dont forget the gapps package for the rom..... now turn the tablet back off......
power the tablet back on like before holding power button and volume down.... once in here, RCK will already be highlighted, if its not, use your volume down key to get it highlighted... once highlighted, hit volume up and this will boot the twrp recovery you flashed......
Once in TWRP, (FIRST DONT FORGET CLICK BACKUP AND MAKE A BACKUP OF YOUR CURRENT ROM!!!) now, make sure you can see your cyanogenmod rom file and gapps by clicking install and going to the ocation where its at, if you see the 2 files, click the back button to the main screen.... on the main screen, click : Wipe, then click factory reset.....after that, go back to the wipe screen, and click system to wipe the system partition..... now go back to the main screen again....
Click install, then click to install the cyanogenmod rom.... after it installs, install the gapps package.... after that, you SHOULD be good to go, reboot the tablet by clicking reboot to system.....
I think that covers everything..... now in the future for flashing other roms, always wipe before flashing and flash the roms the same way you did this one.... just so you know, not ALL roms require gapps package.... most specify whether they do or not....
Any problems, let me know unless its the "waiting for device" thing, i cant help with mac drivers, someone else will have to

I simply cannot seem to get the MAC to do this. I just don't know what command lines to use in the "terminal". I am amazed that no one has flashed their tablet with a MAC.
Anyone who has done this with a MAC, please drop a line if you can. I would really like to get this done if at all possible.
I am unlocked, I get all the way to the "flash" commands, and then it seems to not want to cooperate.
HELP!

I wanted to close out this thread and thank everyone who jumped in to try to assist me. I was not able to flash my tablet, nor get the Cyanogen mod loaded. Not sure why, but, as I try to load TWRP, I get a "permission denied" error.
Eventually, I will get my hands on a windows computer and give this another shot. But, it should have worked on my MAC as easily as anything else. Not sure exactly what I am doing wrong, but, my tablet is working just fine so, I know I did not "mess" anything up (YAY).
If someone has been able to "flash" and put a custom rom on their ASUS Transformer using a MAC computer, please get with me and let's chat!
Again, thanks everyone for taking some time to walk me thru this! I learned a lot, so your efforts did not go to waste! I great appreciate it!

not sure exactly how a mac works but i believe its some sort of linux. can you by chance start the terminal with "administrator" priveleges or type "su" in the terminal to get root priveleges? Just my thoughts with a "permission denied" error, you dont have administrator/root access.
In that link i shared above about mac and fastboot, it says to use " ./ " in front of every command. So try the fastboot commands i said above to flash the recovery but do it with ./ infront like this: ./fastboot flash commands

Well, I used Motochopper to root my tablet, so, I'm not quite sure exactly what you mean. So, I am rooted, my BL is unlocked.
My tablets boots in "fastboot", I just can't seem to get the flash done. At this point, I am not so sure I could be more lost. LOL!

In the steps I told you above. The part where you do the fastboot commands in the terminal. "fastboot flash 0x(somenumber) recovery twrp.blob"
put a ./ in front of the fastboot command... so its "./fastboot flash 0x(thatnumber) recovery twrp.blob"

Recovery no longer allows me to select files from memory (twrp)

I updated now I can't do anything. Im able to book ROM and to boot into recovery but am no longer able to select anything while in recovery.. basically if i want to changes roms or whipe data and etc.. i can't do that anymore..

After doing some more extensive reading and trials and errors.. these two threads where helpful
[UNLOCKED BL] Method 2: Update using fastboot
Notes:
You will keep all your data
This is the best method to update your tablet if you want to keep all your data, and the safest one
Ensure you have the correct drivers for the tablet installed on your computer, or you will have a "waiting for device" error
To update using fastboot, follow this steps:
If you don't have fastboot yet, download it from here an unpack it somewhere on your computer
Extract the Asus firmware file and put the blob file inside fastboot folder
Open a command line on fastboot folder (write "cmd" on Windows search bar at the Start menu, and then
Code:
cd "FOLDER WHERE YOU EXTRACTED FASTBOOT"
, or you can just use SHIFT + RIGHT CLICK on the folder and select "Open command line window here" or something like that)
Reboot the tablet holding the volume down key until you see some icons. Use the volume down key to select the USB icon and then volume up to select it
Connect the tablet to the computer if you didn't do so
Write
Code:
fastboot -i 0x0B05 flash staging blob
, hit enter and wait until it completes
Hold the power button for 10 seconds to reboot the tablet
You are now updated to Android 4.2

and to install recovery I used this step from the same thread
[UNLOCKED BL]-- Installing TWRP (Recovery) --
Since this new update brings a new bootloader, older recovery versions from 4.1 won't work at all. Don't try to flash one!
This guide will give you a recovery that works just fine on the new bootloader. And yes, it can read/write to an external SD just fine. Follow this steps to install the new recovery on your device:
Connect the tablet to the computer
Reboot the tablet using the proper button on the power menu, holding Volume down until you see three icons (RCK, Android and Wipe Data)
Download this file and unpack it (it contains fastboot and a version of TWRP 2.5.0.0 that works with the new bootloader)
Open a command line on the extracted folder (you can use the instructions I wrote in Method 2 if you don't know how to do this) and type
Code:
fastboot -i 0x0b05 flash recovery twrp.blob
Wait for the script to complete. Once it is done, reboot the tablet by holding volume down and power button for 10 seconds or using
Code:
fastboot reboot
on the command line. Don't enter recovery directly!
You have now the new recovery for Android 4.2 .

Hi All,
I really hope you can help me out. I am a fairly unexperienced user who was actually quite proud that I succesfully managed to install Katkiss 7.1 a few month back (just to give you the impression what a noob i am in this field). All worked fine until yesterday when i wanted to startup my tablet again. It got stuck at the ASUS screen right at the start.
I've tried to hardboot it via the little hole as well as to use the pwr+volume down option to boot. Both end up at the ASUS screen.
I could get into the fastboot screen but when I enter RCK and can see the different options there, the screen becomes unresponsive so I cannot select anything there. I can also not move the 'swipe to unlock' feature, so I cannot use any of the options there.
The following information is shown when i use the pwr+volume down option:
Key driver not found......booting OS
Android cardhu-user bootloader <1.00 e> released by "ww_epad-10.6.1.14.10-20130801" A03
Starting fastboot USB download protocol
I've tried to connect it to my W7 PC. Via explorer the internal and external memory can be seen and entered. I've also connected it to ADB and enter the command Fastboot Devices. This came back with a response of letters and digits. Then i tried to Fastboot –i 0x0B05 flash recovery boot.blob. That also worked. When I rebooted the device via Fastboot reboot, I got stuck in the ASUS screen again. (my best guess was to repeat the steps i've taken to flash it the first time, but perhaps I made the situation only worse...)
I've browsed many topics but since none of the issues I could find exactly match my issue (my biggest problem is i guess not being able to manouvre in the TWRP menu on the tablet), i'm a bit 'scared' to just try out the given answers there as it might do more harm than it will help.
I would be very grateful if you could guide me in how I can get my Tablet to work again (if at all possible)...
Thank you very much in advance,
Paul
You did not do anything terribly wrong - I think - so let's try to fix it.
To help you understand what you are doing I am going to dissect the fastboot command for you:
fastboot - doh, name of the protocol or program you are using, starts the exe
-i 0X0B05 - Asus vendor code, not strictly necessary
flash recovery - what to do, in this case flash something to the recovery partition
boot.blob - name of the file you want to flash to the partition specified above
So in this case you flashed a file called boot.blob to the recovery partition. Since you did not specify the file path to boot.blob (C:\myuser\fastboot\boot.blob) the file has to be in the same directory or file folder as your fastboot executable.
Now, the question is: What's in boot.blob? Is that a compatible recovery? A kernel? Who knows? Fastboot relies on you flashing the correct files, it has no way of checking if the file you specified is a compatible recovery or your utility bill accidentally renamed to boot.blob. The result suggests boot.blob was not exactly a working recovery.....
So check your fastboot directory for a file called boot.blob. Get rid of it.
Then download a fresh copy of TWRP 3.1 or whatever version you prefer as long as it is 2.8.7 or newer.
Place that file in your fastboot directory, unzip it if necessary. It should have .img extension
You can leave the file name as is or change it to something easier to type - that's up to you
Then flash it to your tablet:
fastboot flash recovery <exact file name>
Reboot and check if you can enter recovery
If you can, wipe /data, cache and Dalvik and reboot
If it still does not boot, format data, reflash the rom and gapps and reboot.
If one of the steps don't work come back here and we'll troubleshoot
Good luck
Hi Berndblb,
First of all thank you very much for your ample response! I will try to answer your questions to my best ability.
So in this case you flashed a file called boot.blob to the recovery partition. Since you did not specify the file path to boot.blob (C:\myuser\fastboot\boot.blob) the file has to be in the same directory or file folder as your fastboot executable.

Yes, I've located this file in the same directory on my PC as the ADB software is located. This i've read in one of the instructions.
The boot.blob file i fetched from this location: http://forum.xda-developers.com/tran...rea51-t3049395
it was part of this package: twrp_tf700t_kang_2.8.7.4-signed
It was the same file I used serveral month ago when i loaded the Katkiss Rom. I see now that it was actually written by you!!

The version I currently have is 2.8.7.4 so this should be OK if I read your description, however it does not have the .img extention, it contains this boot.blob file + a META-INF directory. Since this file worked the last time, i renewed it and send it to the tablet via the flash recovery command which indeed renewed my TWRP!
However, the screen is still inresponsive so I cannot move the Slider to accept to continue or keep 'read only' settings. When the screen is locked after some minutes I cannot unlock it due to the same issue. I've tried to place the tablet in the dock with keyboard and mousepad but with no luck....
Based on this, should i try to download a newer version of TWRP (3.1 as you suggested)?
If so, i browsed the forum but could find a download link to install in on my PC, only via the appstore to send it to my Tablet(https://forum.xda-developers.com/showthread.php?t=1797692)
Sorry for being such a pain....
That sliding button can be very sticky. Try holding it for a few seconds and then sliding or just fool around with it until it releases. Could be as easy as that

I'm afraid it's not in this case...even if the screen is unlocked (when i first enter TWRP), i cannot select any of the tabs as my touch is not recognized....
Btw, i upgraded TWRP to the latest version i could find for the TF700 (3.2.1.0) but still the screen is inresponsive to my touch so I cannot select anything.
Do yo have the keyboard dock for your 700? - NP
Hi Nektopoli,
Yes i do have a keyboarddock, but unfortunately this does not work either. There is no mouse cursor visible and the lock/unlock button does not work either.
Thanks for your help.

Can you try the a mouse with the keyboard to see if it will bring up the cursor. - NP
No, there is no support for the dock or any of its functions in either TWRP or fastboot.
This is very strange and I almost suspect a hardware failure. Maybe your touchscreen died...
Last thing I can think of on the software side is flashing the stock blob in fastboot. That would replace all the original drivers. If the screen is still unresponsive on stock it's gotta be a hardware issue.
Let me find a link on that...
Here are the instructions: https://forum.xda-developers.com/showpost.php?p=72801448&postcount=8
Link to the Asus website is broken again. Get the Asus firmware here: https://www.androidfilehost.com/?fid=817550096634791660
Thanks again for your suggestions!
I do hope it"s a driver failure indeed...I will try this solution as soon as I am back home from my short business trip. I will of course let you know if it worked.
Thanks again,

I use the dock so I have mouse functions in TWRP, on my TF201 I have the reverse X-Axis with the touch screen so having a working mouse, but that is the only way. Like you said no touch-pad in TWRP. - NP

I've downloaded the drivers from this link but on all three mirrors the BLOB file is corrupt according to WinRar. I receive an error message that there is an error in the 'control number' (freely translated from Dutch) and 'the archive is unrecoverable'.
Do you happen to know any other source I can find these files?
Thanks in advance!

Are you erasing the recovery partition with the fastboot command [fastboot erase recovery] before you try to flash the TWRP blob with [fastboot -i 0x0B05 flash recovery c:TWRP LOCATION HERE]? - NP
Did you check the md5 of the zip you downloaded? This file has been downloaded multiple times and always was OK. Winrar does not have any business touching the blob. Why is it reporting it corrupted? You are not trying to extract it or something are you?
But you can try searching for "Asus TF700 Firmware" and see if you can find the Asus repository

No, i did not use this command so far.
I assume I should do so before uploading the blob file i used a few months back?(which the first post was based on; finding a solution for the tablet not being able to boot past the ASUS start screen)
This topic evolved into the screen not being responsive in TWRP but perhaps solving the issue mentioned above might resolve this latter issue as well.
Thanks,

1st you need a working TWRP [recovery console] which is what erasing and flashing the recovery partition should give you, once you get a working TWRP you can wipe the rest of the tablet and flash the ROM, SuperSU and GApps. - NP

But the tablet still hangs on the ASUS start screen.
Then i've uploaded the latest version of TWRP again, but still I cannot use the touchscreen....
I'm afraid this is all that can be done and i need to accept my tablet died, or do you have some final remedy i can try?
Thanks,
You have to flash the TWRC recovery console, not the system. But if you don't have a working touch screen your tablet might be bricked. - NP

The tablet is not bricked if you have fastboot. You may have a hardware problem, but we don't know that yet and the only way to find out is to flash the Asus firmware blob in fastboot.
I just downloaded the firmware zip from my Android File Host site and checked the md5 - the file is fine. But here is the link to the Asus repository, took about 30 seconds on Google to find it: https://www.asus.com/us/supportonly/ASUS Transformer Pad Infinity TF700T/HelpDesk_BIOS/
I don't know what you are doing, but you are not following my instructions, so I really do not know how else to help you. There no "drivers' to download or install. You need to flash the stock blob as I described before
One last time:
Download the 10.6.1.14.10 firmware
check the md5 sum to make sure you do not have a corrupt download. If you do not know how to do that, google it. Plenty of instructions out for that
Unzip the file you downloaded
Copy the file called "blob" into your fastboot directory
run the commands I posted one by one
When done your tablet should boot into a JB 4.2 rom. If the touchscreen still does not work you need to replace the LCD/digitizer combo or give it up for dead.

I'm sorry Berndblb, I was really trying to do exactly that what I understood you told me, however i am really a noob on this so have sometimes a hard time to understand.
Since I do not know how to check the md5 sum, i tried your other suggestion which was to google on firmware. However i see now that you meant a ASUS repository (i dit not know what this word repository meant) so i just took the first decription which seemed to match my search query. The result was a ZIP file containing a META INF folder and a blob file, so I thought i got what i needed. I should not have used the word drivers, I meant just firmware.
Again my appologies. I really did not mean to annoy you.

I have tried again, the download from the primary link is for me really slow (>5 minutes) and is often interrupted. After completion I checked the MD5 (this time taking your advice to google on how to do it) of the zip file i downloaded US_epad-user-10.6.1.14.10. For me the result was that the MD5 did not match the code given on the site. I received this: 8b9553195579ac5958a4a65141009c92 while the site reported this b407002737b48fb76d04b6542b828634

Thank you for the link. This file i could download without any difficulties. However I could not find where the MD5 was stated on this site for the file which i downloaded, nor did i find any .chksum file or anything. I also tried so read the source code of the site, but this is way over my head and could not find anything that matched the MD5 I found of the downloaded file itself.
I would be interested to learn though where I can find the MD5 for this particular file/site when it's not stated like on your own site (I mean https://www.androidfilehost.com/?fid=817550096634791660). Anyway, the MD5 i got for the WW SKU 10.6.1.14.10 download (2nd from above) is a368c6096db38d375dc799273376d804 (I took the ww SKU because that is what my tablet showes when i use power+volume down: ww_epad-10.6.1.14.10-20130801" A03)

I took step 1, 3, and 4 and used the commands you posted in this threat https://forum.xda-developers.com/sho...48&postcount=8 to take step 5.
(step 2 I did not do because I could not find the MD5 stated on the website itself so have nothing to verify the MD5 I found in the file with)
Although I could see on my tablet that the blob file was installed (it displayed a blue progress bar) , the end result is still the same, the tablet does not boot but hangs on the ASUS screen you see directly after you power it on. I've waited for approx 30 minutes, but it does not come past it.
If the touchscreen still does not work you need to replace the LCD/digitizer combo or give it up for dead.

This I could not check as I could not boot up the tablet
I hope I did everything right this time.
Thank you again for your support, i really do appriciate it!!!
