[Q] How to manually upgrade TF300TG - Transformer TF300T Q&A, Help & Troubleshooting

Hi I am running a TD300TG with ICS and setup nvflash as well.
Now I wanted to upgrade to JB but already flashing JB with TWRP gives me a failure after a while.
In ICS the update file is as well recognized as an update, but this will lead me to TWRP as well...
I tried following this guide: http://forum.xda-developers.com/showthread.php?t=1845377
Maybe you already did it successfully?
I am roote, unlocked, nvflashed...

”just wanted to share what worked!
1. Grabbed the Firmware file (_epad....zip) from the Asus site.
2. Unzipped twice to get to the blob file.
3. ran: fastboot -i 0x0b05 flash boot blob
-- this failed with an error 0x170003
4. ran: fastboot -i 0x0b05 flash recovery blob
-- ran this even though I would have thought it should have been flash boot. Others have suggested that you just
run this program one or more times to achieve success. The good news is that it worked and after:
5. fastboot -i 0x0b05 reboot
I now have a fully functioning device again. I hope this helps others.”

Hi All,
I have some really odd issue,I have installed new custom ROM(Frankly I tried several ROMs)For some reason in recovery it shows like update completed,however when I'm rebooting the device, it stuck on Asus screen.
Any idea how to fix that issue?
Thanks in advance,

I have tried to flash new stock rom with adb shell, but I got error:
"protocol failure"
So I have solved the issue by replacing boot.blob file.
I took boot.blob from SWM ROM and pushed it into sdcard.
===============================================
fastboot -i 0x0B05 flash system boot.blob
fastboot -i 0x0B05 reboot

[Q] TF300TG Unable to update/flash rom via recovery (both TWRP/CWM) Status 7

Hello!
So, this is my first post here at XDA, so bear with me if my question has already been answered somewhere else. If so, pretty please point me to it and I'd be forever grateful, 'cause I really have searched for it without really getting somewhere. Of course, that might because I'm a real beginner at this and just cannot patch the bits and pieces of info together properly.
Background to problem
I have a TF300TG. I have unlocked the bootloader via official channels, and flashed CWM 5.5.0.4. Then I flashed CM9 stable, and got stuck in a bootloop. This was solved by a wiping of cache/dalvik and maybe a factory reset (don't really remember). Anyway, i managed to boot is, and realized that i could no use the 3G functions. Stupid i know, should have read more about it, but I finally realized that there are almost no custom ROMs for the 3G version of this transformer. So, what I now wanted to do was flash to something that would work.
I've read that it's only stock or the Hydroponic roms that are available for the TG-version, so I chose to try the Hydro. However, I read somewhere that I should use TWRP instead of CWM to flash, due to some kernel update-thingies, that CWM would not be able to do. If I understand it correctly, I needed to update the kernel back to the stock kernel, since I came from a cyanogenmod with a different kernel (?).
Flashing TWRP via fastboot was easy, and then I flashed the hydro TG rom from TWRP, which gave me bootloops again. Now I could not solve the bootloops via wiping cache or factory resets, nothing solved them. I tried reflashing several times, and also tried flashing after reverting to CWM again. This flash also worked, but I still got the bootloops.
Where I'm at at the moment
I have tried to flash the stock ROMs from Asus, both 9.4.4.40 and 9.4.4.28. However, they do not flash at all from recovery. I get a Status 7 error no matter if I use CWM or TWRP. And yes, i have extracted the downloaded .zip once, before flashing.
I have tried the fastboot -i 0x0b05 update update.zip command, but only get this:
Code:
archive does not contain 'android-info.txt'
archive does not contain 'android-product.txt'
error: update package has no android-info.txt or android-product.txt
Extracting the blob from the .zip and using fastboot -i 0x0b05 flash system blob does not work either, and outputs the following in the cmd prompt
Code:
D:\Mobil\Android\TF300TG\roms>fastboot -i 0x0b05 flash system blob
sending 'system' (796653 KB)...
OKAY [140.798s]
writing 'system'...
FAILED (remote: ()
finished. total time: 141.204s
and the following on the tab
Code:
[COLOR="Red"]Failed to process command flash: system error(0x170003)[/COLOR]
I have wiped system, cache, data etc from fastboot, so the pad is pretty much clean from everything except recovery partition. Maybe there's somehing wrong with the partitions, 'cause when I try to format them - system for example - i get the following:
Code:
D:\Mobil\Android\TF300TG\roms>fastboot -i 0x0b05 format system
formatting 'system' partition...
Formatting is not supported for filesystem with type ''.
FAILED ()
finished. total time: 0.005s
My questions are these:
How do I flash back to stock, with a stock kernel, if the above things have not worked? Is there a way to flash via ADB that could work, instead of recovery or fastboot?
What's the deal with sometimes flashing the .zip files, sometimes .blob files, and sometimes .img files? I'm confused.
What does the status 7 error mean? Don't really get it from what I've found in my searches.
Can i somehow use the /staging partition to install? If so, how do I push the file there, and which file exacly should I use?
If anyone has any suggestions, I'd be forever grateful. And remember, I'm not an experienced android tinkerer, I have only a Desire HD with CWM and CM7 since before, which was done pretty much by following step-by-step guides and not much understanding from my side. ;P
If you need more info, just let me know.
Cheers!
Niklas
Update:
I managed to flash the hydro rom via CWM. It is still stuck on the Nexus 7-like bootanimation, though. Can't understand why it does not boot all the way into the OS. Ideas?
Update 2
I followed the tip here., and it seems to work. I managed to flash the non-3G version of the hydro rom, and could boot into the OS. Then id somehow worked to flash the 3G version, without any wipes. This time it said "updating android" and then booted! It does not recognize the SIM card, though, but I'm getting more confident that I will be able to fix this now.
So, I have been able to update to the Hydro rom, and can use the tablet, but since 3G is not working in those ROMs, I want to revertto stock ICS. However, I still get the Status 7 error when trying to flash the stock zip from Asus siste. Have tried .40 and .28 WW SKU, none of which is working. Cannot flash the roms in either TWRP, CWM or via fastboot.
Does anyone know what the problem could be? Can it be that the files are not really base roms, but only meant as updates to previous installs? If so, where can I get a base stock ROM?
Nah the work as full recoveries. What boot loader version do u have?
You can reflash stock kernel, by flashing stock ROM through fast boot.

Hey, thanks for answering. Where do I see the bootloader version? Kernel version is 2.6.39.4-00003-gafee6c5 [email protected] #1
I tried flashing the stock rom via fastboot, using the blob inside the update package
Code:
fastboot -i 0x0b05 flash system blob
I've also tried flashing the ZIP in CWM and TWRP, and I have unzipped the downloaded zip one time as the instructions say.
When you load in recovery mode it tells you boot loader 9.1 or 10.4

Ah, OK. It says bootloader (2.10 e) released by "WW-epad-9.4.4.40-20120704" A03.
I would try to load jb..
Just visiting the threads with the custom Roms for this device makes my device brick...
I'm sure you can bring it back, another thing you can do is let the battery in the unit fully die then try.

OK, then I just have to wait patiently for Asus to release JB for the TG-version. Had hoped to be able to solve it beforehand, but hopefully that will finally solve it for good.
Thank you for your time.

too many details, none of which I was looking for
but here's my questions/recommendations
1. Are you on ICS? If yes what version of TWRP did you install there's 1 for ICS and 1 for JB
I recommend making sure you've installed TWRP for ICS and use TWRP to flash the official ICS firmware from the asus website
once everything is confirmed working then install Hydro for ICS TF300TG
2. If you're on JB. Unfortunately there is currently no going back to ICS. Also the Hydro JB Rom to my knowledge currently does not suport TF300TG, and I'm not aware of any ROM for TF300TG that is running JB
I recommend making sure the correct version of TWRP is install then, use it to flash the official ASUS ROM
hello
yes i'm on ICS
1. i use CWM
hum that's not me that have problem
i answered on the last post ...
sorry for my bad english, i speak normaly in french
Hi nikwid,
thanks for the detailed description!
Here's my story: my TF300TG is on stock 9.4.4.22, and I can't update to stock 9.4.4.28 nor 9.4.4.40. It's working normally, except the ugly screen flicker in the left lower corner and WIFI reconnect delays. The latest ASUS update promises to fix these issues, that's why I really would love to flash it.
History
Unlocked device
Flashed Root + CWM
Everything went flawless up to this point. The TF300TG is still on stock ASUS system.
Current situation
When flashing with CWM and TWRP I get:
Code:
Finding update package...
Opening update package...
Installing update...
script aborted (no error message)E:Error in /sdcard/WW_epad-user-9.4.4.40.zip
(Status 7)
Installation aborted.
fastboot outputs (no matter if flashing to system or staging):
Code:
writing 'system'...
FAILED (remote: ()
finished. total time: 142.102s
I don't dare to try `format` with fastboot, as I don't want to brick the Transformer.
I would be happy for any hint how to successfully update from stock to stock?
See you,
Berny
I seem to be stuck in the same situation.
I cannot install "WW_epad-user-9.4.4.40.zip" from within TWRP2 (2.6, 2.5 and 2.4 tried) and I cannot do "fastboot" as I get the same error messages as the others reported here.
This thread is old, but maybe today someone knows the answers?
I successfully installed WW_epad-user-10.4.3.9.zip by editing META-INF/com/google/android/updater-script in the zip and removing everything except the line
Code:
assert(package_extract_file("blob", "/tmp/blob"), write_raw_image("/tmp/blob", "staging"),delete("/tmp/blob"));
Later on I installed the other two packages (SAM_6260_ALL.fls and TF300TL_AMSS.MRP) one by one.
After this I successfully installed WW_epad-user-10.6.2.3.zip by just removing all "show_progress" and "set_progress" lines in the updater-script.
Finally the original WW_epad-user-10.6.2.6.zip installed without editing it (TWRP 2.5.0.0).
Now I can even check for new updates using the tablet, this didn't work since installing root and CWM
HTH!

By the way, I think that deleting all lines in "META-INF/com/google/android/updater-script" except the following one
Code:
assert(package_extract_file("blob", "/tmp/blob"), write_raw_image("/tmp/blob", "staging"),delete("/tmp/blob"));
will do the same as extracting the "blob" file and flashing it with
Code:
fastboot flash staging blob

Current status: I can install an Asus Stock ROM by extracting the blob file and flashing that with
Code:
fastboot flash staging blob
The fastboot command never reports finishing (in this situation), so I stop it by pressing Ctrl+C in the console window, but only after giving it enough time, e.g. 10 minutes, to finish.
Code:
sending 'staging' (800933 KB)...
OKAY [135.726s]
[COLOR=Red]writing 'staging'...[/COLOR] [I](here it stays forever)[/I]
From this moment on no fastboot commands (e.g. "fastboot --reboot") are accepted until I manually reboot by pressing the "Power" button for 10-11 seconds . During reboot there will be a progress bar underneath the ASUS logo, which moves to completion within 10 minutes. After that the system reboots and the clean Stock ROM is installed.
I tried this on my TF300TG by
resetting it by "full wipe",
then via nvflash to an Android 4.0 Bootloader (if you are on a 4.0 Bootloader, go here: http://forum.xda-developers.com/showthread.php?t=1894867 !!!)
and with the latest Asus Stock ROM
4.0.3 (TF300TG: WW_epad-user-9.4.4.40.zip) and
4.2.1 (TF300TG: WW_epad-user-10.6.2.6.zip).
for TF300T (without 3G) there are different Asus ROM version numbers, you can find them here: http://forum.xda-developers.com/showthread.php?t=1697227
Remember, going to Asus Stock ROM 10.6.*.* will give you Bootloader for Android 4.1 and 4.2 which are not downgradeble to 4.0 unless you already have the nvflash backup files created with 4.0.

I can't read the error from that video but i think you should flash a boot.img via fastboot and then flash CWM or TWRP recovery the same vai (via fastboot). BTW you have to use a boot.img from a JB rom.

HEADER – Header stuff (ignore it)

blob.LNX – boot.img
blob.SOS – recovery.img (e.g. regular boot.img)
blob.EBT – bootloader.bin (ignore)
Do i have to rename blob.LNX to boot.img or i should't ?
Do i need to erase all system boot recovery data?

What do you mean with "Yes i can use nvflash"? You already used the NvFlash tool and have the backup files or is just the fact that you are able to boot in APX mode?
As for the other question, yes rename the blob files ( blob.LNX - > boot.img) and flash from fastboot (fastboot -i 0x0B05 flash boot boot.img). Make sure your battery is full, just in case.
Try to flash the recovery.img, boot.img and system.img using the abive method.

Being able to boot in APX doesn't mean you can use NvFlash to flash your device.If you never used the NvFlash tool to backup your files (and gain NvFlash access) you won't be able to do it anymore because a 9.4.5.26 or lower bootloader it's needed.
I'm not sure if the follow procedure will work but you could try to flash the complete blob via fastboot (rename the original asus blob to something like " tf700t.blob " , something like this : fastboot -i 0x0B05 flash staging tf700t.blob
Someone please correct me if the " flashing to staging" procedure is different.

ATM there's no way to do that ,Asus locked the bootloader pretty tight this time.
If you still can't manage to fix your issue i would recommend you an RMA ticket from Asus.

[Q] Softbricked Tf300t

Hi I have been reading a ton in the forums trying to figure out how to fix my tf300t. A few days ago I updated to the newest CM 10.1 nightly and when it restarted it was stuck at the Asus screen. So I have been able to hold vol down button and get to a screen that says
RCK Android [usb symbol] and Wipe Data
I have fastboot access and thought I would try to fix the problem myself by following instructions on another thread
"pyovue - If you have ADB access then unbricking it should be easy as you can push and edit any file on the system with it as well as fastboot? Or can ADB & Fastboot not mount (not just the sdcard) anything? If you don't care what happens to your tablet MB, then try this....
fastboot -i 0x0b05 erase system
fastboot -i 0x0b05 erase recovery
Then reboot (this should rid you of your bootloop to recovery and nothing should start)
Then download the stock ASUS Rom (from ASUS, look under Firmware)
Then try sending it with fastboot -i 0x0b05 flash system blob (you will have to extract two zips from the firmware files until you get to a file called "blob" then put it in your fastboot)
I almost guarantee if you have fastboot/adb working there is ALWAYS a way to fix it... only a hardbrick is impossible to fix.
"
I get cannot load 'blob' so I tried
fastboot -i 0x0B05 flash recovery recovery.img
seeing as I already had the recovery.img from when I first unlocked, rooted, and put cm 10.1 on it
please help I have no idea what to do and thank you in advance <3

What's the question again? If you have fastboot, you can always flash the system blob from your PC. Or you can push the rom (zip) to your internal storage, turn it off and on again. If you select rck on official recovery, it should look for the zip file on its own and proceed to flash it. If you have custom recovery, get to it and flash the same zip file. Make sure you have the right recovery for the rom though. Good luck.

Please try this:
Go to Asus and dl the latest Stock. Unzipp it 2 times. You should have a blob file now in the extracted folder. Put this blob in your fastboot folder.
Open cmd and type:
fastboot -i 0x0B05 flash staging blob
Let it run. It seems that nothing is happening for about 5 Minutes. The whole thing can take up to 20 Minutes, so just stay calm and wait till it’s finished.
Now you should be back to full Stock with Stock recovery. Good luck!
THanks !

Please try this:
Go to Asus and dl the latest Stock. Unzipp it 2 times. You should have a blob file now in the extracted folder. Put this blob in your fastboot folder.
Open cmd and type:
fastboot -i 0x0B05 flash staging blob

Thank you ... it worked i think
but i used a little different command line i used :
fastboot -i 0x0B05 flash system c:\adb\recovery.blob
now i'm still having problems trying to flash custom recovery i want to root the Tablet
what the problem seems to be for me is that i boot the the tablet (tf330t transformer 4.2.1 JB )
to fastboot mode then i get the 3 choices (RCK, Android,Wipe Data)
but when i try to flash the TWRP recovery img with Fastboot it always gives me an error saying (error cannot load img file)
is there anyway to fix this ? and does this root the tablet?
Dear daveSAPIEN can you give us more information about the file used during the flash , actually am facing the same problem as you but nothing seems to work
thank you
