Trying to use ADB to flash_image on Desire Z

Hey, I've been following Cyanogen mods guide about flash_image to flash PSFmod onto my phone. I can use ADB to push files to my SD card and stuff, but when I follow this:
Code:
Temporarily allow app to run from the sdcard (use mount to find the correct device for your sdcard, ie: the /dev/block/BLAH part)
mount -o remount,exec /dev/block//vold/179:1 /sdcard
cd /sdcard
./flash_image recovery /sdcard/recovery.img
But I get this error:
Code:
error scanning partitions
Does anyone know how to fix it?

You get that error from which of those commands ?

From flash_image.
Whenever I run flash_image from my phone now, I get that partition error.
Is it because I'm on a Desire Z?

Where did you get the flash_image utility from ? Was it from somewhere that has verified it to work on DZ ?

Dude u might brick ur phone lol ...try using Rom manager .....its safer

I would use fastboot to flash a new recovery. You're sure what you're flashing is ok for the Vision, right ?

How do I use Fastboot? It should be okay for it, as it's the G2 version of Psfmod.

If you've got adb all setup via installing the SDK etc, then fastboot should work fine too. I think you need the engineering bootloader though.
Boot the phone into fastboot by holding down the trackpad button and holding the Power button, with the phone off. Or you can put it into hboot with Volume Down and Power and then select "Fastboot" from the menu.
It should then say "Fastboot" on the phone. With the USB cable plugged in that should say "Fastboot USB", and if you run "fastboot devices" on your PC it should show up your phone in the same way that "adb devices" normally would.
If that's all working you can run "fastboot flash recovery filename.img" to flash "filename.img" to recovery.

You haven't got S-OFF. You need S-OFF to flash a custom recovery.

I do have S-Off, I followed this and when I boot into fastboot it says "S-OFF" in green text at the top.

Do a checksum on the eng hboot before you flash it, as per the guides, to make sure it's not corrupted.

plug the phone in fastboot, you should see fastboot usb in red.
Open a cmd as admin or terminal as root in the pc
type: fastboot oem rebootRUU (you will get a black splash with silver htc)
fastboot flash zip "nameoffile.zip" (no quation marks)
Once it is done (it says OKAY. finished in the CMD session)
fastboot reboot
Make sure that u are in the same folder (in CMD) where the zip file is...This will only be feasible for a RUU...not a rom. It also works for radios and CWM recovery....:good:

It shouldn´t take that long. Make sure that you are using the oem cable. That USB ports are working fine and there´s no other stuff connected to your USB ports.

Many thanks!
I too had this boot problem on a bad flash through the Hack Kit
(my fault by the way). From power on it took 20 mins to get to the first white HTC screen . Then a further 10 mins to start normal boot.
Apart from the LONG boot, everything worked perfectly. Using TermEm I could boot into bootloader and recovery. The rom, IceColdSandwich worked perfectly in every respect but the corrupted boot was doing my head in.
Using your tutorial, I managed to flash the correct bootloader and now all is good.
hboot before was 0.85.2007
hboot after is 0.85.0024
Sorry if this is a long post but I think it is worth it. Here is a log of the fastboot process:

I have to say that the timings, because of the LONG boot, are completely wrong, . I was tempted to pull the plug on a number of occasions but I gave myself a talking to and went for a coffee.
The whole process took about 2 hours and I am now the delighted owner of a normal booting DHD.
To anyone who wants to attempt this procedure, the watchword is patience. Whenever you think nothing is happening, DO NOTHING!
The different stages will eventually happen just as laid out as per Glevitan. Good luck with your attempt.
Once again, many thanks.
Edit: Just an afterthought, at one stage Windows had a failed attempt at installing usb drivers that ended up as an 'Unknown Device'. Just ignore it and keep going.

Edit: I just tried again and it worked, nevermind!
Just fyi: if you get an error after flashing the ZIP, just flash it again.

Thanks! This was helpful.

Toolkit Rooting Question FAILInvalid Command"

I'm confused.... I'm following all the instructions using the toolkit v10.
I was able to unlock the bootloader without an issue, but when it comes to rooting, I'm having problems.
I use option 16 for the build, then option 4 to root. In the fastboot screen, the bottom Fastboot status says FAILInvalid Command as soon as it pulls up, then it goes to "reboot" after the 30 second wait.
It doesn't reboot automatically, so I press the power button to reboot it myself. then it reboots and then goes back into fastboot with the fail invalid command. Then this comes up:
downloading 'boot.img'
FAILED (remote: Invalid Command)
finished. total time: 0.006s
Waiting for device.
I'm at a loss. I feel like last time did this, I had to get the factory image and the boot.img file from somewhere and place them in the folders within the c:/galaxy nexus toolkit folder.
Any help would be greatly appreciated!
Thanks,
Nick

put on your big boy pants and root your phone this way:

I have tried that... i get a similar message:

then the fastboot status on the phone changes to "download 005d9800"
not sure what to make of that either.

is the cwm/twrp image actually named recovery? and is it in the fastboot.exe directory?
are you typing the command correctly? ( fastboot flash recovery nameofrecovery.img

It's in the same "platform-tools" folder that the fastboot.exe file is in. it's called recovery-clockwork-touch-6.0.2.3-toro.img, so i type fastboot flash recovery recovery-clockwork-touch-6.0.2.3-toro.img and hit enter. That's what made sense to me in reading that post.

nexus 7 lte 2013 stuck on the merging circles

I tried the guide "How to root Android using Ubuntu" to root my device. It's a matter of overcome absurde limits like the otg, and stuff. My hope was to be using a step by step guide, but that's not completely true, as I sadly discovered. The procedure involves some operations with fastboot to unlock the bootloader and superuser utility to complete the task (already copied the recovery image through fastboot, of course). Now, I didn't realize, nor it was written on that <MOD EDIT-SWEARING> guide, that the su utility had to be put on the internal sdcard BEFORE to start the job.
Thus I started the job, unlocked the bootloader. Then I should have installed the zipfile (the superuser.zip) but not having it on the device, I chose to reboot from the cursor menu. The logic behind this was simple: I have unlocke the bootloader, not erased the os or whatever, thus it shoul restart; I don't have the needed file on the device, thus after a reboot I might copy it over through usb cable, enter again in recovery mode and "install the zip from sdcard".
From then on my device is stuck with the 4 merging/bouncing circles and I *cannot even turn off * it.
I'm a gentoo user, used to read and write guides "in a certain manner", everything was done under gentoo, where I'm now.
Situation now:
Code:
# lsusb
Bus 003 Device 027: ID 18d1:4ee1 Google Inc. Nexus 4 / 10
# fastboot devices

Before my mistake, it was:

or
Code:
Bus 003 Device 014: ID 18d1:4ee0 Google Inc.
and
Code:
# fastboot devices

The exact procedure I followed:

nexus: turned on in fastboot mode (hold volume-down + switch)

To that point I faced the fact that to continue I should have copied the superuser utility before, and rebooted with the hope to be able to copy it on the device and continue from there on. What has been proven false: I'm now stuck on the bouncing circles, any experiment to hold down the 2/3 buttons in every combinations led to nothing, and "fastboot devices" shows nothing.
only positive point, a little hope: it shows a vendor and product ID via usb:
Code:

Please help! :crying:

Can you go to recovery?
Edit...
You can turn it off by pressing power+volume down, same for going to fastboot/recovery...
In recovery you can flash via adb sideload...

Thank you for the tip. At first, apparently it was not working, I hadn't written that message in such a panic, otherwise. I said myself: another guy, expert on the subject is saying this... must retry again. Worked.
I fully recovered the device by flashing it under windows with the Nexus Root Toolkit, and was able to definitely root it by following a more updated guide for my linux habitat.
Given that, as a newcomer I'm not supposed to post any link, I'll give easy directions (searchable through google) to other panicked newbies like myself.
Part1: the recovery issue (windows)
The communication under windows isnt' that easy, due to the difficult coexistence/conflict between mtp an adb drivers. For the purpose of flashing we need adb drivers. The best way, shamingly overlooked by me, is to read and try (possibly understanding the concept behind) step1...step4 accessible by mean of the large button in the main windows of root toolkit.
Part2: rooting succesfully (inux)
I found a functional guide, with working links, kindly offered by Gregory Schier. Had I followed that one from the start, the process had gone smooth at first shot.
Let me add, for the linux addicted, a reference to the file-transfer-via-usb-cable topic. In my case it was easy and quick after the very short explanation on MTP found in gentoo wiki.
Thank you for your support :good:

Good for you!!!
There are actually many ways to root our device ,specially with unlocked bootloader...

I just used fatboot OEM unlock I find it easier and most definitely safer toolkits work 99.999 % of the time but when they don't you got yourself a mess

[Q] Nexus 7 2013 Problems...

A couple days ago, I was browsing the internet, then my Nexus 7 2013 suddenly froze. I did a reboot, but it got stuck on the boot animation. So, since it wasn't booting back up, I tried to load from one of my old backups. I managed to get the back up to work, however I needed to download the 4.4.2 update OTA through TWRP. It never officially said it finished, but I restarted the tablet and it's been stuck on the Google screen. I've went to fastboot, but it wont let me into TWRP recovery since it only loads the Google screen. I've also tried this ( http://www.androidbeat.com/2013/11/flash-factory-image-nexus-device/#.U0o0z3nn_0x ) and it didn't work.
When I try to reset through WugFresh, I've flashed KRT16S 4.4 and KOT49H 4.4.2, and and I get
Code:
sending 'bootloader' (3911 KB)...
FAILED (command write failed (Invalid argument))

I've also tried a few other ways of restoring to factory settings but nothing has worked :crying:
Any help is much appreciated!

I deleted my OS on my nexus... Oops? what I did is I did a ADB Sideload custom rom but if you can't get into twrp you are screwed. Maybe send it to Asus or return it if it is under warranty and get a new one. Just remember don't listen to me, in just a child on a tablet at night trying to unpack full posting privileges.

Couldn't you go into your bootloader, erase your recovery using ADB, and then flash it?

Alright, thanks I'll try this as soon as I get home. Though, when it says to type "fastboot flash bootloader bootloader-grouper-3.34.img" will I just be able to substitute the new 4.4.2 factory image stuff instead of the older? Also, does it matter that I can't set my Nexus into debugging mode?

Yes you will need to replace by the "bootloader-grouper-3.34.img" by the name of the img in your device archive.
For my Razorg / deb (The LTE version) it will be :
Code:
fastboot flash bootloader bootloader-deb-04.02.img
and
Code:
fastboot -w update image-razorg-kot49h.zip
And for the Razor / flo (Wifi version) it will be :
Code:
fastboot flash bootloader bootloader-flo-flo-04.02.img
and
Code:
fastboot -w update image-razor-kot49h.zip
For reminder, factory images can be found there : https://developers.google.com/android/nexus/images?hl=FR#razor
Debugging mode / ADB is not nessesary until you write the bootloader in fastboot mode
But don't forget to install drivers, except if you already do this step
I hope i helped you.

You mustn't flash grouper bootloader on flo/deb!
Only the bootloader that belongs to your firmware.
Yet I'm not sure if your USB driver is installed properly.
Are you 100% sure it is?

that link is great!...
Don't worry you are not screwed...just follow the link the person above posted about how to hard reset your nexus device. Since you have a 2013 nexus just make sure that you download the correct nexus image and make sure you flash the correct files and you will be fine. I have used that same tutorial on my nexus 7 2013 flo and deb to fix issues.
Trust me it will work...

The files in folder look fine now
Did you update your SDK manager to the newest version? (Especially sources regarding API 18 and 19 are important). Move the firmware files elsewhere before, because by major updates whole platform-tools folder will be replaced.
Try to use different USB port on your PC. Once when you are in fastboot mode, does this command work?
Code:
fastboot reboot-bootloader

Well, just my 2 cents... I read somewhere else on this forum from someone having the same issue that replacing the cable he used actually did the trick for him. You might try that. Won't hurt..

Did you update your SDK manager to the newest version? (Especially sources regarding API 18 and 19 are important). Move the firmware files elsewhere before, because by major updates whole platform-tools folder will be replaced.
Try to use different USB port on your PC. Once when you are in fastboot mode, does this command work?
Code:
fastboot reboot-bootloader

I haven't updated the SDK. So when I do, just be sure to move the image files and whatnot, and then put them back after the update, correct?
I'll be doing this later

Yes just move your firmware files (bootloader and image.zip) out of the folder.
Updating is easy, double-click SDK manager application (you will see it as soon as you open SDK folder) and there you can choose what to update. You just need an internet connection.

i am intrigued to see if this person was able to fix his tablet...
I think that all the suggestions above are very good ones. Making sure he has the most updated software...
Make sure he tries another usb cable or make sure you are using the stock usb cable.
And trying another usb port...
However from this fastboot devices output it did show that his device was connected which i don't think would happen with a default usb cable.
Okay so here is what i think may be causing the problem.
I think you need to unlock your bootloader before you can erase it. Try following this tutorial -> http://forum.xda-developers.com/showthread.php?t=1907796
You have to unlock it before you can erase the bootloader. So you need to do:
command 1: adb reboot-bootloader
command 2: fastboot oem unlock
then you can do:
command 3: fastboot erase boot
try that and see if that helps....
If that does not work then try flashing the new bootloader over the old one.
I hope this has been helpful.
Don't give up...

LOL, good point @droidshadow!
Hey, @PieceofSlice, is your bootloader possibly still locked? Please make photo of the text in bootloader mode on bottom left and post screenshot of it.

I'm pretty sure my bootloader is unlocked, my tablet has the unlocked padlock at the Google screen. I'll take your advice and try a new cord too

So I actually tried to do this because, even though I updated the Android SDK, when I typed in "fastboot erase boot", it basically froze on "erasing bootloader." When I tried the first command, "adb reboot-bootloader", it said
Code:
C:\android-sdk\platform-tools>adb reboot-bootloader
error: device not found
So I take it I have a problem with ADB or something?

There are two generally different modes by using Android Debugging Bridge:
1. ADB (device booted in OS or recovery)
2. FASTBOOT (device in bootloader mode)
When I tried the first command, "adb reboot-bootloader", it said
Code:
C:\android-sdk\platform-tools>adb reboot-bootloader
error: device not found

So, if you have tried this command above when your device was in bootloader mode, it was wrong command, as the command should have started with "fastboot...." instead of "adb..."
If the device was booted in OS, this command would have been correct and such response could have two reasons:
* USB debugging was not enabled
* drivers are not installed properly
After updating SDK manager, it is always highly recommended to check if the driver still works.

Careful, mate, I hope you didn't try to erase your bootloader? That would have fatal results. Actually "boot" means kernel! As long as your bootloader is there = your tab will be fine.
By flashing a factory image the order of doing things is
* erase all (kernel, system, userdata etc)
* flash new bootloader
* reboot bootloader
* flashing whole factory image zip file
