Hi guys please help.
Dont know if I posted it in the right placed.
I cant post it in the relevant thread since it is a dev thread and i'm a noob
So this is my first android so i'm basically super noob (my technical record was to Jailbreak an iPhone)
My error seem pretty simple but I could not figure it out.
I'm trying to flash the CM10 ROM according to this:
http://forum.xda-developers.com/showthread.php?t=2027304
What i have managed to do:
Unlock bootloader.
root with RootBoot V5.
install SU and flashed TWRP recovery for Intl version with the amazing Hasson2000 all-in-one tool.
Where I got stuck:
now i downloaded the CM rom zip file and the its specific kernel.
changed the kernel name to: boot.img
placed the file in the kernel folder (of the tool).
hit the flash kernerl (marked the 'with this command').
the CMD window opened, and showed this error:
error: cannot load 'Kernels/boot.img'
picture - http://sdrv.ms/YtPHoU
triple checked the file name and the right directory
I would appreciate any help!
Thanks
My device:
HTC One X+ international unbranded
1.14.401.16
I think your making things too complicated using this kernel flasher software.
Just download and install the Android SDK. Once installed find the platform-tools folder, copy your kernel .img to that folder, connect your phone in fastboot mode. Then hold shift and right click, choose open command window from the contex menu. Then just type into the prompt "fastboot flash boot boot.img" (or the name of the .img).

Thank you guys for helping me.
I tried both methods and recieved the same error in both of them in CMD:
error: cannot load boot.img
Lloyr method:
4 files in fastboot folder:
adb
AdbWinApi.dll
fastboot
boot.img
entered fastboot from device ----> plug in to pc (debugging is on by default) ----> run CMD from this folder----> writing command "fastboot flash boot boot.img" -----> error message
AndroHero method:
download the Android SDK (zip file named adt-bundle-windows-x86) and exract it to desktop.
in the folder adt-bundle-windows-x86, i went to "sdk" and then "platform tools".
copied the boot.img file to "platform tool" folder and ran the CMD from this folder.
typed the command "fastboot flash boot boot.img" and boom ----> error: cannot load boot.img
thanks again
>.< you NEED to be in bootloader
type in adb reboot bootloader and make sure you are in fastboot usb (select it if it's not already done for you)
then
fastboot flash boot boot.img

Sorry if I didn't mention that.
i was on fastboot USB.
showed fastboot USB on a red backround.
I tried once again with both methods and i recieved another error message in the SDK methos:
error: cannot load 'boot.img': Unknown error
I attached file with step by step screen shot for the whole process (both methods).
Just thought...did you rename it boot.img? If so and file extensions are hidden then it will be boot.IMG.IMG so remove .IMG and it should work fine

Make sure you installed HTC Sync (htc site) and the drivers will come with it. (you can later remove sync, drivers will stay)
Then enter fastboot trough vol down + power > choose fastboot ... plug your phone to PC and wait sec for driver install.
Make sure u see Fastboot USB in fastboot
Go prompt admin mode and go to your c:/fastboot map (put boot.img in there)
And type
Code:
fastboot flash boot boot.img
After that install recovery and rom and boot.

Thank you thank you thank you!!
Long story short I f'd up trying to install cyanogen. The only thing I can do on my phone currently is enter the bootloader. I've tried going back to stock by using the ruu zip through cmd, yet it always gives me a signature verify fail. When I've ran ruu.exe from my pc it gets to the final step but gives me an error when trying to find my phone.
I'm hoping since I can at least get in to fast boot that there is still hope.
also sorry for clogging the forum with another troubled phone story.
What did you do on the install? Cyan installer, download and install from recovery? A little more info please

This is the instructions posted by Scotty85
I'm just re-posting it for you

here is how you extract rom.zip:
Quote:
the .exe utilities can be finicky,so if you have trouble getting it to run, you can extract "rom.zip" in the following manner:
-start the utility
-check the "i understand" box to move on to the next screen
-hide the utility temporarily out of site
-search your C drive for "rom.zip". you will find it in a temporary location(it will be in a different spot each time you run the utility)
-open the folder location,and transfer rom.zip to a safe location on your PC.
-unhide and cancel the utility,youre done with it.
-rom.zip can be flashed using
adb reboot-bootloader
fastboot oem rebootRUU
fastboot flash zip rom.zip
fastboot flash zip rom.zip (yes do this 2 times)
fastboot reboot
Quote:
here are some directions to flash "rom.zip"
if youre working with a booted,operational phone,you can flsh the file in the following manner:
-open a cmd window
-change to adb/fastboot directory
cd c:\foldername
(cd c:\mini-adb if youve used any of my guides )
-place the zip file you want to flash into adb/fastboot directory
-enable usb debug,disable fastboot,plug in phone
-check for connectivity
adb devices (should return serial number)
-boot to fastboot
adb reboot bootloader
-check for connectivity again
fastboot devices
-flash the file
fastboot erase cache
fastboot oem rebootRUU (will put you in ruu mode,black screen silver htc letters)
fastboot flash zip zipfilename.zip (will send and flash the file. dont interupt it while the cmd window shows its writing, and the green status bar is moving on the phone screen)
*sometimes a file will fail with a pre-update error. this is normal,just enter again:
fastboot flash zip zipfilename.zip
and this time it will finish
-when you get "finished" and "OK"
fastboot reboot-bootloader (takes you back to fastboot)
-reboot back to the OS
fastbooot reboot
you can use this if you dont have an operational phone as well. you just need to manually put the phone in fastboot(select from hboot menu) then skip the "adb" commands and start with fastboot devices
to answer your other question,yes,you will need to re-unlock and re-install recovery after running the RUU. an ruu is designed as an "unroot" solution, or emergency fix,if other attempts have not made the phone operational.

how to flash boot image using fastboot command prompt.... actually i did this while i unlocked my phone.... now i wish to flash baidu rom 4.0.4 by AKA_Noodle....
ramakrisna
What is difficulty?
You need adb and fastboot. If you don`t have it, download from here & unpack it in e.g. C:\Android.
Also download rom what you want, e.g. baidu rom 4.0.4 by AKA_Noodle. Open it via Winrar & take out boot.img, put it in C:\Android.
Don`t forget to copy rom to sdcard
Then open DOS Command Prompt
Code:
win + R > Type "CMD"
Connect Desire V to BB by USB cable & type in Command Prompt window
Code:
CD C:\Android
adb reboot bootloader (your device should reboot into fastboot mode)
fastboot flash boot boot.img
Reboot your Desire V into recovery mode & flash rom via CWMrecovery.
Of course you need a properly installed drivers.
I am using TWRP to install a flash (Because the Phone is getting stuck a HTC's logo) and after I finished flashing it, I reboot and it gets me back to TWRP so it's not working. What to do?
How did you install TWRP on your device? it must be Fastboot-ADB folder where you have already copied the recovery .img file. Open the command window in this folder by Shift and Right click combo and type the following command with the part of command of your recovery image file:
fastboot flash recovery(yourRecoveryFileName) and then type .img at the end of the command – hit Enter
The process of installing of your chosen custom recovery will now start on HTC One Max.
I have four files-
1- Stock ROM file
2- Vbmeta
3- boot.emmc.win
What is the correct order of flashing these files and what ADB and fastboot are required to do so?
Follow these steps to sideload adb
1.Boot into recovery
2.Tap on upgrade from USB
3.Go to your computer and open a command window
"Click Shift and Right click simultaneously"
4. Type the following command
Adb sideload file name.zip
5.Wait for the process to complete
6.Reboot your device
