Error fastboot when i flash the recovery

[petitbuzuc]

Hello

I try to install a custom recovery on my tf701 (android 4.3, USB debug ON)


here are the previous steps i did :
1/ i have unlock the bootloader using ASUS tools : OK
2/ i have root the TF701 : OK
for this, I installed Minimal ADB and Fastboot
I copy the files found here
and I lauch the command : adb reboot bootloader
then : fastboot boot zImage_dtb ramfs.img.gz

the root is ok
-------------------------------------------------------------------

3/ i try to install recovery
i download the file here : droidbasement.com/asus/tf701t/recovery/
i put the file in the folder of Minimal ADB and Fastboot
and i launch the commande : adb reboot bootloader
then, when the fasboot usb mode is ready on the device : fastboot flash recovery recovery.img

first time :
target reported max download size of 64382
sending 'recovery' (6652 KB)...
FAILED (data write failure (Unknown error)
finished. total time: 5.050s


second time :
target didn't report max-download-size
sending 'recovery' (6652 KB)...
FAILED (remote: (Timeout))
finished. total time: 2.010s



Can you help me please ? I add that, when the device is ON in a normal mode (not fastboot) and connected to the PC with USB, the adb driver interface are ok :
"
C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices
List of devices attached
* daemon not running; starting now at tcp:5037
* daemon started successfully
E1OKCY174091 device
"

i have tried to plug on other usb port ... it's the same ...
i have tried to reboot my computer : ... it's the same ...
i have tried to download another version of adp/fasboot (platform-tools_r28.0.2-windows.zip) : it's the same

without this installation, I can't install a custom rom ..

Many thanks in advance !

There are only two working recoveries for the TF701, one CWM without touch interface which I don't quite trust and a pretty good TWRP with touch here https://www.google.com/amp/s/forum....-kang-twrp-tf700t-2-8-x-xarea51-t3121989/amp/
The one you have there is probably the stock recovery...
The Kang TWRP is a little buggy though. You may come to a point where TWRP tells you it cannot mount /system or any other partition for that matter. All you have to do is convert the file system on /system to ext2, then convert it right back to ext4 and proceed with rom installation.
Good luck!

Hello berndblb
Many thanks for your help

The recovery I try to install is Recovery v6.0.4.6 CWM 11.

Which one is the easier to install for a beginner ?
Because what you said previously seems difficult for me ("convert the file system on /system to ext2, then convert it right back to ext4 and proceed with rom installation.")

Can you explain me how to do ?

Recovery v6.0.4.6 CWM 11 or Kang TWRP : can i install then the Rom "
ROM][N 7.1.2] [ KatKiss - Nougatella #037 ] for asus tf701

?

Many thanks in advance

They are equally easy to install since you just flash both of them in fastboot
But if you are asking which is easier to use, then it is the Kang TWRP. CWM does not have the drivers for the touch interface and you have to navigate everything with the vol buttons. More importantly I do not trust the "format data" function in CWM and that is crucial to install a custom rom. The issue with the corrupt file system in the Kang TWRP is a minor nuisance and you fix it right in TWRP. If you get the "cannot mount....." error, you just go to Wipe > Advanced > Change or repair file system, check the System partition and convert it to ext3 (or ext2 - does not matter). Swipe the button and when it is done (less than a minute) you repeat the step and change it back to ext4. After that everything should be good. If you want to read more about this issue search the Katkiss thread for "cannot mount"

Actually, there is another custom recovery out there which I have not tried and cannot vouch for. But maybe you go for that one, it does not seem to have the same issue and is based on a later version of TWRP: https://forum.xda-developers.com/tr...lopment/recovery-twrp-3-2-1-x-tf701t-t3720912
Read the thread, it seems to work fine. The Kang TWRP is 2.8, that one is based on 3.2.1 - both are fine to flash a Katkiss rom.

You do know that you have to fully format /data before you can flash a custom rom, right? You do that in your custom recovery (in TWRP: Wipe>Format Data, swipe the button). TWRP does a secure erase which wipes and trims every block. That's why this formatting takes around 60 minutes. Do not interrupt it!! CWM does not have this functionality, another reason I prefer TWRP..

hello berndblb and all helpers !

i have installed the Kang TWRP: it's ok
then I copy the custom rom KatKit for TF701 on /sdcard

i do a full wipe : error : "cannot mount..." : so I convert to ext2 and then I convert to ext4 the partition System and data
then i do a full wipe

my problem ... i'm sure you find it : i have erased all my data on /sdcard. No kitkat.zip yet !! :crying::crying::crying:

how to copy the rom on my tablet ?

for your information, when I am in TWRP, i can do "adb devices" on my computer :
C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices
List of devices attached
15C4110C61C00000009FB01C0 recovery


But push commande is failed
C:\Program Files (x86)\Minimal ADB and Fastboot>adb push KatKiss.zip /sdcard/
adb: error: failed to copy 'KatKiss.zip' to '/sdcard/KatKiss.zip': no response:
Connection reset by peer


i put kitkat.zip on a USB Key and I plug it on my docks : it seems not be recognized ...


i 'm really lost


please help !!

Put the Rom on a microSD, mate. You can navigate in TWRP to the card and flash from there

Hello !!
I have nevers seen the microsd port ! I discover it 2 days ago !
Just before your answer, a 'adb push' was successfull ! I don't know why, and the next 'adb push' for gapps ans supersu were unsuccessful...it's strange !

But all IS ok now !
I have just a last 2 questions :
1/ next Time, where Can i copy the rom (.Zip) , somewhere it will not be deleted ?
2/my tablet is not rooted now ... Is the way to root depends on the Rom ?
If I follow the steps i did when my tf701 has the rom stock, IS still good ? (https://forum.xda-developers.com/showthread.php?t=2516215)

Thanks for your help !

1) the safest place is a microSD. You can flash the Rom straight from there. But as long as you do not format your data partition - and you only need to to that if you install a different rom - you can keep it on internal storage. In most cases you only need to wipe /data, not format, and that leaves /data /media where your files live, untouched.

2) First the question is: Do you need root? You should only root your rom for a good reason. If you are not sure if you need root - you don't.
Cyber threats are multiplying. You're safer if the tablet is not rooted.

That said: you can root by just flashing the zip in recovery.

BTW, if you did not flash gapps yet, you always should flash it together with the rom, not separate. To install gapps now flash the rom, then gapps, then root (if needed), reboot
