Bootloop and can't access to TWRP - Asus Transformer TF700

Hello !
Well, after long research and testing some solutions, I create this post because I'm stuck at one point.
So, after a wipe in the fasboot mode, my TF700 get stuck into a bootloop with no access to recovery (The more I can have is 5 second with the TWRP splashscreen before rebooting). The ROM that was installed on my tablet is Cromi-kk.
I followed this help thread : http://forum.xda-developers.com/transformer-tf300t/help/guide-t2854495 and I'm stuck at the last point
Code:
fastboot -i 0x0B05 flash system boot.blob
Here is what it said on my computer :
Code:
[email protected]:~$ sudo fastboot -i 0x0B05 flash system boot.blob
erasing 'system'...
OKAY [ 2.355s]
sending 'system' (800927 KB)...
but nothing is moving on the computer, and the tablet is still displaying the fastboot screen...
So I really don't know what to do now, I hope one of you can have a solution
Thank you in advance !

Heck! I cannot believe this went undetected for so long!!! @lj50036
Hey Josh, have a look at this and make the edit! LMAO
@nhibel: Assuming you are trying to flash the stock blob in fastboot and you extracted the stock rom zip twice and put the file called just "blob" into your fastboot folder, the command to flash the stock blob is
Code:
fastboot -i 0x0B05 flash system blob
Nothing is happening because fastboot cannot find a file named boot.blob. Which makes sense since it does not exist. Unless you unpacked the blob.....

I don't think it's because of that. On the help thread it is said to rename the blob file into boot.blob, what I've did ^^
I tried again with renaming the file to blob, but it's the same, nothing is happening :/
Code:
[email protected]:~$ sudo fastboot -i 0x0B05 flash system blob
[sudo] Mot de passe de camille*:
erasing 'system'...
OKAY [ 2.431s]

Maybe you can try the BUSTER99 way to access your bootloader.

Show me a screenshot of your fastboot folder with "show extensions" enabled and make sure the blob is not named blob.blob.
I probably would start from scratch: Delete all blobs from the fastboot directory, extract the blob from Asus firmware, drag it "as is" into fastboot directory and use the fastboot flash system blob command

Here is some good news !
At first, I was trying to flash the blob from a Linux computer, but it wasn't working. So I tried again from another computer, which running on Windows 10. Again, it didn't work, exactly the same than on the Linux computer.
Finally, I tried something else. When I was looking for solutions at the beggining of my problem, I've dowloaded a twrp.blob, but I was unable to flash it at this time. I just tried again, and thank of the help of the help thread, I finally succeeded to flash TWRP (I had to try 2 times before the flash succeeded), and I should be able now to flash a rom !
Well, I lost everything that was on my device, but it works !
Thank you so much for spending some time to help me !

[LINUX] FastBoot Protical On Your Vega (DEV)

Hi iv been testing this for a while and iv gotta say ..... its amazing the vega can do something the xoom cannot .... fastboot boot. Witch for a rom dev saves a lot of time
Ok this is relatively safe but is dev only thing so use with a little cation :-D as always dont blame me for a brick
[Video]
Watch it here
http://www.youtube.com/watch?v=llZ3qYSlLUE
[GUIDE]
From recovery
1) extract the .zip from below and allow the fastboot binary to be executes
2) reboot to recovery
3) format boot partition in recovery
4) reboot (now your device will drop to fastboot)
5) it will do this every boot until l boot.img is restored
From NVflash
1) extract the .zip from below and allow the fastboot binary to be executes
2) boot into APX mode
2) format boot partition with nvflash ( ./nvflash --bl bootloader.bin --format_partition 7 -go )
3) (now your device will drop to fastboot)
4) it will do this every boot until l boot.img is restored
[OTHER INFO]
Seeing as the vega reports as a different vendor we have to specify this in the fastboot command some examples can be found below
./fastboot -i 0x955 -b 0x10000000 boot zImage ramdisk

There is a video of this now in the main post
What is the advantage of this fastboot for a developer?
I remember getting that prompt when I switched from USB Slave to USB Host on Paul's Modaco ROM. I was quite clueless (I opened a help thread both here and in Modaco) and only re-flashing the stock ROM helped me any.
Nice work!
Does this allow you to push e.g. kernel images from my pc to boot on-the-fly or does the images need to be on the device already?
Sorry if that seems like a dumb question
FastBoot means that the device boots off a ROM image on your PC, instead of a burnt ROM. This has no advantage to non-devs (other then possibly brick protection, but they are pretty unbrickable as is).
To be clear: This does not make it boot "faster" and it probably has no use for you. Move along
Just checking. This'll be really useful in testing all of my broken kernel builds
how exacly does this work. Ive tried building roms in the past for my defy but got fed up with bricking it trying to bring the defy back to life was a real pain in the ass.
I would like to have a go with the vega if this makes it simpler.
Does it mean i can boot an image that is on my pc whilst leaving the internal image the same?
and can i simply re boot and have every thing as it was befor?
thanks in advange for any help!
I've extracted the advent .exe file to see if it'd be possible to re-flash the full stock ROM without having to use Windows. I got successful in reaching Fastboot mode, and when I execute ./fastboot I see a command which says "flashall", which would flash "boot.img", recovery and system.img. Would that be enough to boot safely? I see as well the possibility to execute an "update" command. If I converted the adventupdate.exe to adventupdate.zip, would said command flash the contents (aka the ROM?).
I may be saying foolish things, but I am curious about this.

[Q][Kernel][i9023] Help : flashing kernel killed my phone

Hello everybody,
Before telling you about my issue, i should mention that i am a complete newbie regarding flashing kernels. This was my first try, and it didn't work out too well.
I needed to test the USB OTG/Host Functionality for a project at work, and i read that it was possible to enable it on the Nexus S by flashing a custom kernel (kernel_usbhost_build5_icsnexuss from sztupy). It's probably worth mentioning that prior to this i updated the phone to Android 4.0.3.
So i started this morning by rooting it, unlocking the bootloader and installing CWM.
At that point i realized that the recovery mode wasn't accessible : the graphics of the droid with an open belly appears for half a second, and then it gives me the black screen treatment for about a minute before rebooting.
However since there are other ways to flash kernels, i figured i could do without recovery so i didn't look more into it.
I then flashed the kernel using fastboot with this command :
Code:
C:\Program Files\Android\android-sdk\tools>fastboot flash:raw boot H:\data\Downloads\kernel_usbhost_build5_icsnexuss\kernel\zImage
creating boot image...
creating boot image - 3446784 bytes
sending 'boot' (3366 KB)...
OKAY [ 0.422s]
writing 'boot'...
OKAY [ 0.500s]
finished. total time: 0.922s
From the trace i figured that all went well, but when i reboot it stays blocked on the splash screen with the Google logo. Since then i tried flashing several other kernels, without any success. Also tried to flash an update.zip (both ICS and GB) over fastboot but i get this error :
Code:
C:\Program Files\Android\android-sdk\tools>fastboot update H:\data\Downloads\upd
ate.zip
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
So to sum it up i now only have access to the bootloader, without recovery mode.
Before you all jump on me, i know what i did is bad habits (i should have tested the kernel before flashing it), i did it in a hurry without checking i had all sufficient knowledge, and to be honest i would probably have been more careful if was doing it on my personal device.
Truth is now i'm really desperate because i turned my company issued phone into a brick and don't have the slightest idea what to do about it...
Is there any guru out there who knows how i could get out of this ?
Thanks a lot !
Download clockworkmod recovery and use fastboot to flash it.
Fastboot flash recovery yourfilename.img
Enter recovery and mounts and storage and mount USB storage
Transfer the kernel you want to your SD card. The one you flashes isn't a kernel I'm almost sure.
Try a different one.
Then transfer a rom to your SD card.
Factory reset/full wipe, then go to mounts and storage and format everything except your sdcard.
DO NOT FORMAT YOUR SD CARD!!!
Once that is done go to install zip from sdcard and flash the rom and then the kernel and reboot. Should be fine then. Keep me posted.

The image you need would be this ClockworkMod img. Save it somewhere, cd to the sdk/platform-tools/ directory and then do:
Code:
fastboot flash recovery /path/to/saved/file/recovery-clockwork-5.0.2.0-crespo.img
Just drag and drop the file in your terminal, after typing the space after "recovery".

Ha ha oops! Forgot that part!
I usually just cd to the one where I have recovery saved!

Thanks a lot for answering so quickly !
I'll give it a try on Monday, let you know how it goes.
Election Day said:
Yes, you can also do that, of course. In that case you'd have to provide the full path for fastboot. Or maybe you don't have to on Windows? I don't really use that operating system to be honest.
In that case it would be something like:
Code:
C:\Program Files\Android\android-sdk\tools\fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
Looking at OP's quotes that is probably the most logical way in this case, you're right.
Click to expand...
Click to collapse
No I just cd to downloads (where recovery file would be) in terminal, type: fastboot flash recovery xxxxxx img
And that's it.
I set the path to fast boot and adb in environmental variables in device manager.
Maybe that's why.
..
Just tried out your tips, worked like a charm !
However I had to wipe everything twice before it would let me update to 4.0.3, I would get this weird error :
file_getprop: failed to stat "/system/build.prop": No such file or directory
Anyway now I'm back on ICS and, following your advice, i found another kernel to flash : Matr1x. No problem with this one, now I can test USB OTG.
Thanks again, you guys rule !

[GUIDE][BRICKED] [BOOTS ONLY TO RECOVERY][All ASUS TRANFORMERS]

This is a general users guide to unbrick your Transformer tablet.
This guide will help you if your Asus tablet will only boot into recovery
and the command
Code:
adb reboot-bootloader
does not work to get you booted back to bootloader screen ..
If the above command works then skip to the first fastboot command ..
WHAT YOU NEED
An Asus tablet that will only boot into recovery …
Woking adb and fastboot on your PC
Windows drivers (if using Windows)
A fully charged tablet
Asus data cable
Stock firmware blob (from Asus's web site, make sure you get the right one)
_that's bootit.ko (unzipped and placed with fastboot.exe)
Downloads
Asus Stock firmware---MAKE SURE YOU GET THE CORRECT SKU FOR YOUR TRANSFORMER TABLET
click me
_that's bootit.ko----click me
INSTRUCTIONS
Extract your stock firmware in your downloads folder twice...You will see a blob file rename it boot.blob and move it to the same folder as your fastboot.exe or if in linux to your home folder
Unzip the bootit.ko and place it wth the above blob file.
Let start with this command to make sure that your PC can see your table as an ADB device in recovery
Code:
adb devices
OUTPUT
Code:
[email protected] ~ $ adb devices
List of devices attached
015c7d7a445c260c recovery
Then lets push the bootit.ko to the root of the device like this
Code:
adb push bootit.ko /
OUTPUT
Code:
[email protected] ~ $ adb push bootit.ko /
673 KB/s (27690 bytes in 0.040s)
Then lets insmod this .ko file
Code:
adb shell insmod /bootit.ko
This should reboot the tablet into the bootloader menu, lets verifiy.
Once in the bootloader screen lets make sure your PC can see the device in fastboot.
Code:
fastboot devices
OUTPUT
Code:
[email protected] ~ $ fastboot devices
015c7d7a445c260c fastboot
So now its time to erase the misc & cache partitions, as that is most likely the partitions that is making it boot to recovery...
Code:
fastboot erase misc
OUTPUT
Code:
[email protected] ~ $ fastboot erase misc
erasing 'misc'...

erasing 'cache'...
OKAY [ 2.096s]
finished. total time: 2.096s
Once these two command run with OKAY as the OUTPUT .
It is time to make sure we can reboot into the bootloader with the hardware buttons
So from where you are at in the bootloader screen use the VOL DOWN & POWER buttons to boot the tab back into the bootloader screen ..
Run these command in fastboot in this order
The next command is to just verify your computer can see your device
Code:
fastboot devices

A message from _that
_that said:
Here is the original thread where the bootit module was tested for the first time -> http://forum.xda-developers.com/showthread.php?t=2291974
The problem was that the installed recovery was too old and incompatible with the bootloader and so could not access the eMMC at all. The bootloader command to boot to recovery is stored in the MSC partition (mmcblk0p3), and the recovery could not clear it. Since the bootloader checks the MSC partition before checking for volume-down, it is impossible to get to fastboot without some additional kick in the butt (aka "bootit.ko").
The correct bootit.ko file to use is the one in "bootit-bootloader.zip": http://forum.xda-developers.com/attachment.php?attachmentid=1985941&d=1369339132 - the older version turned out to be too weak. Note that this is a zipped kernel module, not a recovery-installable ZIP. You need to unzip it on your PC before adb push.
After making it to the bootloader menu and working fastboot, you can fastboot flash a current version of TWRP and install the custom ROM of your choice. No real need for the stock blob, unless you want to make sure you have the current bootloader and a known working ROM.
Here is another thread where bootit.ko didn't help, maybe it was really a hardware problem. But lots of good background info from me. -> http://forum.xda-developers.com/showthread.php?t=2437376

It's gonna be a PITA to install that hard drive on this computer as I built this computer because of that POS. I'm unsure but hopefully I can figure out a way to connect both hard drives and have some sort of dual boot to use this hard drive with my new processor as opposed to the AMG with 1 gb of ram in the previous one from 5+ years ago. I already gutted it cuz it's of no use to anyone other than parting out. I have windows 7 on an old laptop I don't use anymore but I'm unsure of how to use that hard drive as to whether I can connect that one to that of my new desktop in a way/shape/or form so to speak

[Q] TF300T TWRP bootloop. Return to stock?

Any help would be greatly appreciated. I recently flashed the new TRWP using fastboot. Went fine. I then tried to wipe and flash the newest version of KatKiss. I thought it also went fine but after reboot, it bootloops TWRP. I can tell the tablet to boot Android, but it just hangs. Then when I try to boot back into TWRP, it starts the bootloop all over again. Here is what it's doing during bootloop.
Running OpenRecoveryScript
E:Could not mount /data and unable to find crypto footer.
E:Unable to mount '/data'
E:Unable to recreate /data/media folder.
Updating partition details...
E:Unable to mount '/data'
...done
E:Unable to mount storage.
E:Unable to mount /data/media during GUI startup.

E:Unable to mount /data/media/TWRP/.twrps when trying to read settings file.
Processing AOSP recovery commands...
E:Unable to mount '/data'
-- Wiping DATA Partition...
Formatting Cache using make_ext4fs function.
After about 1 minute it will follow with...
E:Unable to mount '/data'
-- Data Partition Wipe Complete!
Done processing script file
It will then reboot within 3 seconds after displaying the last line, and begin it all over again.
I'm hoping someone can tell me what options I have at this point. Would I be able to return to stock using fastboot and ASUS's blob from their website? Again, any help is greatly appreciated!
Solved.
I had already figured on buying a new tablet regardless, so I figured I'd go ahead and try to recover using fastboot. It did work. I noticed this post had a few views, and on the chance there were other people having the same issue, I'll post how I did it. I recommend using Windows 7 for this.
Download the appropriate firmware from ASUS's website. (WW, US, CN, JP etc...) Unzip the file twice until you have the META-INF folder and blob file. I placed both of these into a folder named "TF300t" directly on the C drive.
Install your device drivers, I used the Google SDK drivers.
Boot into fastboot.
Run these commands...
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system c:\TF300t\blob (Again, this is where I saved my blob file.)
You should see something along these lines, when flashing your system...

I had already figured on buying a new tablet regardless, so I figured I'd go ahead and try to recover using fastboot. It did work. I noticed this post had a few views, and on the chance there were other people having the same issue, I'll post how I did it. I recommend using Windows 7 for this.
Download the appropriate firmware from ASUS's website. (WW, US, CN, JP etc...) Unzip the file twice until you have the META-INF folder and blob file. I placed both of these into a folder named "TF300t" directly on the C drive.
Install your device drivers, I used the Google SDK drivers.
Boot into fastboot.
Run these commands...
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system c:\TF300t\blob (Again, this is where I saved my blob file.)
You should see something along these lines, when flashing your system...
C:\>fastboot -i 0x0B05 flash system c:\TF300t\blob

What happened if you dont have the blob???
I had a tab, i complete erase all the partition and i cannot install any app, always had error 963
How i can recreate all the partition of my tablet?
It running android 5 lollipop
Regards,
Shouldn't be any reason you don't have the blob file. You can download it straight from ASUS's website. When you download it, it comes in a zip file. You have to extract it twice. So unzip the original zip file downloaded, then unzip the file you get from unzipping the original. From there, you should have the blob file needed to flash your tablet back to stock using fast boot / sdk tools.

Thanks

Hi
After many tries and plug the usb cable in the back of my tower i successful install the firmware
Regards,
HI to rstore to stock using twrp, is it as simple as downloading the file to the tablet, unziping once then flashing the resulting file, or is it a bit more difficult than that?

Returning to stock, where can I find the stock image?

I need to warranty a phone but I need to turn it back to stock. I am using an older version of TWRP, I am guessing here but do I just download the factory image and flash it and I am done? It seems like everything I get when searching is geared towards the Pixel XL and using ADB rather than TWRP.
Thanks in advance.
Beacuse I part time as an internet troll, I have to chastise you for not reading threw this forum, because well that's why it's there, but hey we all can't use our Brian's all the time, but yes download the factory image for your phone Marlin for Pixel XL and Sailfish for Pixel unzip the file, make sure you have lastest usb drivers installed and click the flash all.bat.
Fastboot and flash factory image.

I'm not a good developer so I cannot answer you that question, but on Google official page, it is recommended to use fastboot or adb to flash factory images...

Because recovery and boot are sort of intermingled now. You would be writing over twrp at the same time you are trying to use it to flash.
Use the flashall bat file. If you want to save data edit out the -w from the bat file.

I am on linux let me just get that out of the way.
So I used adb to fastboot the factory image but nothing happens
the file is in downloads and in the fastboot file. So I type cd Downloads, cd fastboot, fastboot sailfish-nmf260 it all looks good and you can tell adm is working but nothing happens on the phone.
I am current only able to get the phone into fastboot mode I dont know what I messed up but I can no longer even boot into TWRP.
I must have succesfully removed the twrp recovery because no i get the no command screen. If I hold power and press up I can get into the stock android recovery. Is there a way to install the factory image still? Or is the process still the same and I need to adb fastboot? I might need to just do the abd fastboot on a windows computer at work tomorrow.

Download the factory image you want here. Unzip the entire contents to the same folder fastboot is located in. Then boot the phone to the bootloader, then plug it in to you computer. Then, if you're using Linux, double click the flash-all.sh file that got unzipped to your fastboot folder. If you're using a Windows computer, double click on the flash-all. bat file instead of the flash-all.sh file. Then sit back and wait. That's about all there is to it. One note. If you want to save your data, open the script you're going to use in a text editor and remove the -w toward the end of the script (remember to save your changes). If you want the phone wiped clean and like new again, just leave it as is.

On the phone nothing happens. It appears that all I am getting is a list of options but none of the options seem to be working either.
I might add that the fastboot folder I am using was downloaded back when I installed twrp is it possible my fastboot file doesnt have the correct files to get the job done?

Have you tried putting phone in fastboot mode and doubble click the flash all.sh file? That's how it is done on Windows.

Basically yes. But with linux you cant just double click. So in terminal I typed "cd Download, cd fastboot, fastboot flash-all.sh" that command will attempt to launch that file.
I feel like the issue is with adb on my laptop I tried making sure its updated but i got nothing so ill try to do it on a work computer when I get free time.
Its pretty crappy right now because I am without a phone but heck I pet the dog today during lunch instead of reading the news feed off my phone so I guess the dog is happy lol.

I don't think you can flash it with fastboot. In Windows, at the command prompt, you just type flash-all.bat and the batch file will run. It contains all the necessary fastboot commands. Perhaps that's where you're going wrong. Try just typing flash-all.sh. Leave the fastboot out.

Try this for sailfish (fix accordingly if marlin, username of course is common sense, if still confused, you shouldn't be using linux)
I build and use debian sid
Code:
cd /home/username/Downloads
tar xvf sailfish-opr3.170623.008-factory-bb8bb3a3.zip -C /home/username
cd /home/username/sailfish-opr3.170623.008
tar xvf image-sailfish-opr3.170623.008.zip
cd /home/username/sailfish-opr3.170623.008
./flash-all.sh
If you need the latest adb/fastboot name it something like google.sh
Code:
#!/bin/bash
wget https://dl.google.com/android/repository/platform-tools-latest-linux.zip
unzip \platform-tools-latest-linux.zip
cp platform-tools/adb /usr/bin/adb
cp platform-tools/fastboot /usr/bin/fastboot

Sorry I wish I could try this. I had access to a windows computer at work and I was able to get everything done. After doing it at work I have a feeling I wasnt placing the files in the correct folder together to get it to start the update. It can be hard doing this on something other than windows for a dummy like me because most of the tutorials for things like this seem to be windows oriented. Regardless its done. I couldnt lock the boot loader on the windows computer though oddly but no big deal because I can do it on my laptop.
Thanks for all the help guys.
