[Q] Fast commands not working

I flashed the ICS OTA on GT-19020 which worked like a charm but now can`t flash CWM with fastboot or even lock unlock.
The error is:
C:\android-sdk-windows\tools>fastboot devices
3634A4391E1900EC fastboot
C:\android-sdk-windows\tools>fastboot oem lock
... FAILED (command write failed (Unknown error))
finished. total time: 0.565s
C:\android-sdk-windows\tools>
any ideas?

Ran into the exact same issue just earlier after I successfully updated my phone to the official ICS (from MIUI). Fastboot flash recovery failed to flash CWM. So I tried to flash teamwin twrp recovery instead, that worked.. I was still not happy why CWM failed. It turned out I may have a bad CWM image. I downloaded a new image from clockworkmod site, flashed it and it worked like a charm..
On a side note, I flashed superuser and su binary but they don't work in the official ICS. adb su commands all worked fine, but in ICS, any app asking for root just fails.. Back to my MIUI ROM now until the issue with superuser is figured out.

It isn`t the cwm image as I have tried several, it is that fastboot can`t write any commands.
Not even lock unlock.
I also get permission denied when I su using adb!
So can`t use flash_image to flash a recovery.
If anyone knows anything please help

I had the same problem. Did you find a solution?

[Q] Can't boot after CM9[SOLVED]

Hey XDA
I tried to install CM9 today, it fail...
I have unlocked my phone using htcdev.com.
Then I followed this:
If you unlocked your phone via htcdev.com, you must flash the included
boot.img after flashing the ROM in recovery:
- Boot into fastboot, either by:
- Turning phone on whilse holding VOLUME DOWN, or
- adb reboot bootloader, or
- using an option in your recovery (eg. Reboot Bootloader)
- Connect your phone to your PC and copy the boot.img from the ROM .zip
to the same place as fastboot.exe and issue the following command:
- fastboot flash boot boot.img
Failing to follow these instructions on a htcdev.com unlocked device will
cause the ROM to fail to boot.
And now it just stands with a mobile and a ret warning sign. I can get in bootloader, but that's all. I have the CM9.zip on the sdcard but I forgot to run it before I did the above mentioned. I have tried to reset the mobile from bootloader nothing helps
Pleas help me what should I do?

So what is your problem exactly ? Do you have a custom recovery like 4EXT ? It's needed in order to apply the CM9.zip.

None
No i have not installed any recovery app. I cant start my mobile

1.install a custom recovery like 4ext or cwm
(2. Backup current system) this time you don't have to do this since you don't have a working system at the moment.
3. Full wipe (data, system, boot, caches... Not sd card) from recovery
4. Flash ROM zip from recovery
5.flash boot.img via adb
6.reboot
7.done
Sent by my fingers to your head.

I'm assuming you know how to boot into fastboot and use fastboot and adb commands. If not, just click on the link in my signature under Helpful links.
Once you're done, just put the attached file in your adb folder, then boot into fastboot and issue the command ;
fastboot flash recovery recovery.img

You will now have the custom 4EXT Recovery. From there, just follow the steps you outlined in your first post, and you should be up and running.
Cheers.
EDIT: I see you already got it working while I was composing my post. Congrats!

@op could you please update the thread title to something like [solved]

tablet only boots into twrp

My TF300T will only boot into TWRP. I also can't access any storage (failed to mount error) and adb sideloading fails everytime so I can't flash the stock rom. I tried using these commands:
adb shell mount -t tmpfs none /sdcard
adb push ROM.zip /sdcard
Which let me reach the .zip file it still failed to flash.
The tablet had Jellybean 4.2.2 installed. The TWRP version is 2.6.3.0.
How do I fix this?

Reboot it into bootloader menu. If holding volume down and power buttons doesn't work try 'adb reboot bootloader' command while tablet in twrp. Then flash rom through fastboot.

Now I can get to fastboot, but if I try to flash anything the cmd window says it worked but all it really does is freeze the tablet.

Did You flash rom or recovery? And does blue progressbar appears?

I was able to flash cwm recovery. So now instead of booting into twrm everytime I get stuck on the splash screen. That didn't really change anything
I tried fastboot -i 0x0b05 flash system boot.blob (the .blob file from the stock rom), and I got the blue progress bar then rebooted but I'm still stuck on the first splash screen.

You do it wrong. So if Your last working firmware was 4.2 You need download this rom from asus webpage. Then unzip it twice and You get blob file. Then flash it with 'fastboot -i 0x0b05 flash staging blob' command.

Thanks. That worked. However now I'm only back where I started. CWM give can't mount error and can't reach a zip file. ADB sideload doesn't work either(failed to write data 'protocol fault (no status)'). I tried TWRP once and that's the reason I had to post hear in the first place.

Did You try only TWRP v2.6.3.0? I use v2.5.0.0 and its work fine. About CWM: flatline cwm for 4.2 bootloader was created with purpose do nvflash backup, so may be here is the cause of not working others functions.

[Q] Cannot Root A510

I have been looking to Root my A510 and drop KitKat on it, but I am stuck trying to install the recovey,img
Steps completed so far:
Bootloader unlocked
adb reboot-bootloader
fastboot oem unlock
fastboot reboot​
Obtained the recovery image 6.0.4.5
Loaded recovery image
adb reboot bootloader
fastboot flash recovery c:\AndroidRootTablet\recovery.img
fastboot reboot (holding volume down)​
Just boots up normally... I can get into the stock recovery using adb reboot recovery, but I see no way to add the recovery image...
A510 version is 4.1.2
I probably have this out of order, but I tried to root the tablet first, but that didn't work either. A few questions:
-- Do I need root before installing the recovery.img?
-- What is the current recommendation for rooting the A510?
This is what I tried to use for rooting:
http://theunlockr.com/2013/06/15/how-to-root-the-acer-iconia-tab-a510/

No need to root before flashing a recovery
You have to reboot in recovery directly after flashing it via fastboot and flash the zip "disable stock recovery"
With a JB bootloader you have to : Hold Volume- (**), and when vibrate, release it and hold Volume+(*) until the recovery load
If you reboot in Normal mode, the Acer ROM will erase the recovery.
Check the initial CWM thread with it's installation guide: http://forum.xda-developers.com/showthread.php?t=1866378
Could be applied with any version of custom recovery

A510 Updated to KitKat
Thank you sir for you help. That hit the spot. I greatly appreciate the work you are doing with the A510.

I would say, from TWRP :
- unistall magisk
- reboot recovery
- flash the rom zip
- flash twrp zip
- reboot recovery
- flash magisk

Sure you can flash it, try 3.3.1-16 !
If you get an error by
Code:
fastboot boot twrp-3.3.1-16-enchilada-Q-mauronofrio.img
try
Code:
fastboot flash boot twrp-3.3.1-16-enchilada-Q-mauronofrio.img
.
