hello, and welcome. i suggest using this rom. its ICS and it's AWESOME!!!!! as for rooting. someone else can walk you through it. once you set up all the files (fastboot&adb) you'll be good to go with a few simple terminal commands.
here's a link to the team Eos ICS rom:http://forum.xda-developers.com/show....php?t=1426838

Thank you, for the suggestion, and on the note of rooting, I've tried the command and I get stuck at the boot loader screen with nothing doing any thing, the computer says waiting on device and the Xoom just sis there at the dual core boot and the words starting fast boot services at the top left hand corner, and it doesn't do anything, I've tried this on two different computers, one using Ubuntu the other win 7 ultimate both do the same thing

make sure you have your adb & fastboot installed to C:/ and no sub folder (this makes sure everything is clean and no interferences). after that you must hard reset your xoom (hold in power button and vol up) than press vol up to access fastboot. after this navigate to your android SDK install directory and hold in left ctrl button and right click on the working folder and hit open cmd here.
also did you try the command fastboot devices? this lists the devices connected to your computer aka your xoom
here's a list of command just in case
Commands:
adb - Android Debug Bridge - One of the two things you'll need to know if you ever want to do anything non-conventional on your android based phone.
List of commands that can be used by adb can be prompted by typing adb at the system shell (command prompt or terminal)
Notable adb commands:
adb devices - If you don't know anything, this is the ONE thing you have to know.
adb devices will give you a list of devices connected to the computer. This is also a good way to make sure that your phone is actually connected to the computer.
adb reboot (bootloader|recovery)
adb reboot - this will reboot your phone normally.
adb reboot bootloader - this will reboot your phone back into the bootloader (white screen with the android on wheels)
adb reboot recovery - this will reboot your phone back into recovery console (either default or amon_ra's recovery).
adb shell - this will shell into the phone and you can now explore the phone. Remember phone's native backend os is linux so know your linux commands.
adb remount - remounts the system partition on the phone so you can you read/write to it.
adb push xxx yyy - will push xxx file from computer into yyy location/file on phone (needs rooted access)
adb pull xxx yyy - will pull xxx file from phone into yyy location/file on computer (needs rooted access)
Fastboot is protocol used to update the flash filesystem in Android devices from a host over USB. It allows flashing of unsigned partition images.
Notable fastboot commands:
fastboot devices - If you don't know anything, this is the ONE thing you have to know.
fastboot devices will give you a list of devices connected to the computer. This is also a good way to make sure that your phone is actually connected to the computer.
fastboot reboot - this will reboot your phone normally
fastboot oem unlock - this will unlock your bootloader - NOTE THIS WILL VOID YOUR NEXUS ONE WARRANTY
fastboot erase XXX - Will erase the partition XXX (such as userdata, cache) - mainly used for resetting phone and clearing userdata / factory settings.
fastboot flash XXX YYY - This will flash XXX partitionn with YYY image.
e.g: fastboot flash system system_update.img will flash/update your system partition with an image called system_update

hi sorry.. had to get to ten posts XD

This is exactly what I did, I used adb to put in fast boot mode and used the command to try and unlock it, tried with files in c drive and in user profile, all just kinda sit there and say waiting on device, though about how long should I wait for it to unlock boot loader? And what will happen once it does, also I'm running Android v 4.0.3

To apply just unzip the contents of the package below into the tools folder of the android sdk
How-to Enter fastboot mode .... While the phone is off hold down "Volume down key" and then "power button" hold both till you get a white screen with the androids and skateboards
to confirm your device is seen by adb use this command
Code:
fastboot devices
you should see your phone listed under the command you just typed. After that type the next command to flash the splash image
Code:
fastboot flash splash1 splash1.nb
Then you should see that it was successful and rebbot the phone and preview your new image by typing
Code:
fastboot reboot
Please Thank and post comments as needed, if there is any trouble i'll try to help if i can i'm rather busy lately...lol
There was a huge thread on how to change splash with win 7 and I am stuck in osx thanks for a tut on how to to it in fastboot
Thanks! I followed the instructions and applied it no problem. Makes booting up look seamless with Fresh's bootscreen
So I have been having nothing but problems with Sync, so have rooted, flashed and changed boot image by using a root file manager (which all have worked fine).
Where on the EVO is the splash screen logo located, so I can just manually apply it?
Thank you

I'm 99.9% sure that this image cannot be simply replaced in a folder but must be flashed, at least that's how it was for winmo
If you think about it this is where the carrier brands the phone the most, im pretty positive this is flashed to a specific partition
Am I missing something? I do everything step by step and it won't find fastboot command in the terminal (using OS X). I can't do anything.

Hmm that's too bad. My Vista sees my EVO, but it has an exclamation mark and the driver won't initialize no matter what I try.
Guess I'll wait till some other time then

Is there a way to flash from the EVO itself? I can copy files with no problem if I connect as a HDD.
add this file to the tools folder of android sdk or i think in OS x anywhere works as long as you direct the command line to it

From what I gather a lot of people have this issue with Vista 32bit and HTC Sync. I haven't been able to track down a solution. Even when trying to use Sync..it always just errors and says:
Unable to find HTC Sync on your PC. Please make sure.....
Kind of a pain, but so far I have been able to do everyting I want just doing it from the phone with files copied over. Using the terminal emu or file manager

Can anyone point me a direction step by step how to root / unlock for my device so that I can flash it with CleanRom?
Really appreciate if got a simple step by step before I can flash it.
and I'm totally do not know what is fastboot, bootloader, CWM and TWRP, anyone can guide me?
If without anything now, can i just download the ROM and flash it directly?

You need to install ADB platform tools (search the forum for it) and proper drivers (I used Universal Naked Driver), then follow the directions in this thread. The driver will enable Windows to "see" your device as fastboot, and the platform tools will allow you to issue ADB commands from within its folder. You need to also put your tab in fastboot mode (if you have custom recoveries such as CWM ot TWRP) by going to recovery menu and select the USB icon.
Note: once in cmd admin mode, you must first navigate to the platform-tools folder, wherever it is located. Ex: cd C:\platform-tools\ assuming that your PT folder is in drive C on your PC.

[KERNEL][28/08/2014]FastCharge kernel for the Kindle Fire HD 7

Disclaimer:I am not responsible if anything I've provided suddenly deep-fries your device or causes alien abductions leading to thermonuclear war.
Hey guys!
For quite some time I've noticed people asking for a solution to the famous battery drain issue of the Kindle Fire HD. To solve this problem,I've compiled a kernel. May I present to you,
The FastCharge Kernel
by SafinWasi​
This is a kernel which has the fastcharge functionality added to the stock 7" Kindle Fire HD kernel. In other words,by using this kernel while enabling the fastcharge function on your device,you can use the full voltage of your AC power source,thereby speeding up the charging like crazy!! Yay!
Features:
By enabling fast charge,reduces charging time using the full power of the AC power source/USB cord connected to PC/car charger/any other power source.
Ensures longer lasting battery life
Easy to use,can be used by complete newbies as well.
Click to expand...
Click to collapse
How to flash:
Download the kernel/boot image and place it somewhere on your PC
Ensure that adb and fastboot can detect your device.
CD (change directory)to the image folder with a command prompt.
In the prompt,enter the following command:
Code:
fastboot -i 0x1949 getvar product
Power off your device and connect it the computer. It should boot into fastboot.
Enter this command to flash the kernel:
Code:
fastboot -i 0x1949 flash boot safinwasi-kernel-fastcharge-20142808-tate-v1.img
Finally,enter this command to reboot out of fastboot:
Code:
fastboot -i 0x1949 reboot
Profit!
Click to expand...
Click to collapse
How to activate and deactivare fast charge:
There are two ways to activate fast charge. 1:Through command line and 2:Through the dev's app.
To activate through command line:
Code:
echo 1 > /sys/kernel/fast_charge/force_fast_charge
and deactivate:
Code:
echo 0 > /sys/kernel/fast_charge/force_fast_charge
Or,you can install the app made by the original developer of the fastcharge kernel. Find it on the Play Store.

Contributors
SafinWasi
Kernel Special Features: Adds fastcharge function to the 7" KIndle Fire HD 2012(tate) kernel. Can be used with fastcharge apps.
Version Information
Status: Alpha
Created 2014-08-28
Last Updated 2014-08-28
[B]Q&A[/B]
Q:My device hangs on the blue Kindle Fire Logo! What happened?
Ans:Your device was running a more recent nightly of CyanogenMod 11,which is incompatible with this kernel. Please downgrade the ROM to an older nightly or the M8 Snapshot. In the meantime,you can access recovery to restore a nandroid or boot into fastboot to reflash your stock kernel.
Q:How can I backup my stock kernel?
Ans:Connect the device with ADB debugging enabled. Then issue the following commands(for Windows):
Code:
adb shell su -c "dd if=/dev/block/platform/omap/omap_hsmmc.1/by-name/boot of=/sdcard/boot.img"
adb pull /sdcard/boot.img

Awesome, Man! I'll flash this as soon as I get a chance. Excellent work!
Figured out why it's not working for me. My wall charger only allows 1 amp to output so I need to buy a new charger.
Excellent. One thing, this kernel have any other feature, or only fast charge?

Sorry, I meant adb in fastboot mode.
Could be device specific, I suppose. @Maromi's kernel breaks my power button. Weird. [emoji51]
Also, I'm running ext4, but I didn't read anything about f2fs in the op.
Not booting past the blue logo for me, either. I tried on F2FS since the guy above said he was on EXT4. It's a dud.
Edit: I am able to boot into recovery and change the file system. I am unable to do much more.

Reflash your rom to get back to booting. You should be able to do it dirty.

Anyone know how to install the ADB Drivers to use adb in recovery?

I know the fastboot and adb drivers are different and I know you can adb from the device while on a ROM but, the adb drivers for recovery are different. Normally, I would right-click on My Computer > Manage > Device Manager & there is a yellow triangle like the one you see in this image above, I right-click on that and select "update driver software". If it doesn't find it automatically, then I > Browse my computer for driver software > Let me pick from a list of device drivers on my computer > Android device > Android Composite ADB Interface. But, that isn't working for me at this time. Any ideas?

[Q] ONE+ Chinese Import / Flash to Bacon issue ? SOS

Hi XDA.
I will try and make as much sense as i can as i am new to rooting etc. Please forgive me if i use incorrect terminology.
Ok so i purchased a Chinese One+ and tried to follow instructions on a YouTube video on how to flash it to the current Cy OS.
This didn't work as planned as my One+ said that there was an issue with "E Footer" so i then followed these instructions to install it via command prompt. (being a new user i cannot post an external link to show you the instructions i followed) However a Google search of E footer is wrong will take you straight to them.
This went well and the install was complete however i was unable to get any signal with my phone network EE. The sim works in my nexus 4 so that isn't an issue.
So i now want to re flash the device using the one plus toolkit but i have hit upon a few snags.
1. I have followed the USB driver guide but cannot find the Samsung drivers on the system to show up to allow me to complete the link between the phone and my win 7 machine.
So currently my One+ shows in device manager as A0001 and not a Samsung android device as the guide illustrates.
2. Do i need o unlock bootloader to flash?
3. The download CM115 link when pressed gives a 403 error so i have downloaded CM11s via an external download but am unsure what one file in the package i need to select to start the flash.
This is all academic however until i manage to get the phone to show as a Samsung Android.
Any help would be appreciated as i am stuck.
Thanks J
Download this: http://builds.cyngn.com/factory/bacon/cm-11.0-XNPH38R-bacon-signed-fastboot.zip
Extract it, reboot your phone to fastboot, connect it via USB and double click the flashall.bat in the extracted folder.
If this works.....
You sir are a legend
Doing it now.....
Im really sorry but there appears to not be a flashall.bat file within the zip.

Right so you have windows good. I'll upload my flashall.bat in a few minutes. Are your fastboot drivers working?
Excuse my ignorance but i have been installing various things all day. I have the phone in fastboot mode however it sounds like what you're referring to is something else.

Go to command prompt and type fastboot reboot. Does the phone reboot?
I've just installed the 15 second ADB installer. However it still isnt working. Here is another screenshot. Thanks again for your help.
Solved the driver issue.
I have jumped onto a dedicated windows machine instead of bootcamp.

Not a problem, anything for a fellow xda user. So fastboot works? Make sure you have the fastboot folder for CM11s on the new PC. Here is the flashall.bat: https://mega.co.nz/#!9UAQRKJS!Kuau0ulgCrxrvE5wBH5Ib54Bv6E64U1RkXje_ONMxUc download it and put it in the folder with the rest of the files and double click it. It should work.

Fastboot is installed however its not rebooting the phone. 4 drivers were installed but it states "waiting for device"
Does the phone need to be in fastboot mode?

Yes, just to test the drivers.
Right got that working but we now have this..
I think we are close!
Ah I see, I think your download had an error
Maybe try it again and make sure the downloaded file is around 487mb

This is the size it should be
Ok re-downloading now.
What state should the phone be in to get this to work. Should I have de-bugging enabled and MTP?

HOW TO UNLOCK BOOTLOADER ON LENOVO TAB TB-7504X

I am using 'fastboot oem unlock' but
Erorr shows me
'fastboot (remote : unknown command)
How to solve this problem
???
Please help me
Download the latest version of fastboot & ADB.
You can see what version adb and fastboot you have installed, just open a command window and type: sudo adb --version (then hit enter) sudo fastboot --version (hit enter key) that will show your installed version of those tools. I believe right now the latest is 31.02 but I could be wrong. It is updated often and using an older release of adb and fastboot can and will cause issues..
Go here to download adb and fastboot. https://developer.android.com/studio/releases/platform-tools
Just download the android sdk for whatever OS you use on your computer, unzip...
What is the device you are trying to unlock? Have you enabled developer options on the phone and changed usb settings to file transfer instead of the default which is charging? Also have if that was done did you keep a close eye on your device because there will be a small box that pops up that must be immediately checkmarked so that your computer can communicate with your device. Have you selected "allow oem unlock"Also in the developer options? it might be good idea to set your lock screen to "none" instead of having a lock set for it. Any time anything is installed on a computer it almost always needs to be rebooted. If you have not done any of that I would suggest doing it all.
Also depending on what device you are attempting to unlock the bootloader on, the wording could be slightly different. My Pixel 4XL uses: fastboot flashing unlock , to unlock bootloader. So keep that in mind as well. If you use Windows OS on your computer some day when you have a minute check out Linux. You can make a "live USB" burn a copy of a Linux distro to a USB drive and boot from it and or install it along with your Windows OS, aka dual boot... The very first time I used Linux, it was Ubuntu and quite a few years ago and I would never return to Windows!! Can't stand it! Linux is made for doing what we do to our phones.
If you need more any help with this some other time and still cannot get it installed message me on here or should I say "start a conversation" with me here on xda. Same thing with the new layout.. My user name is the same here on XDA as it is on telegram. Feel free to shoot me a message any time. It may take a some time to respond depending on what day it is and what time and all that but I will respond.
Here is one of the best guides in my opinion on how to get and setup adb and fastboot tools on MAC, Linux and Windows OS. https://forum.xda-developers.com/t/guide-unlock-flash-root-for-the-pixel-2-xl-taimen.3702418/

Try typing: sudo fastboot --version & sudo adb --version and make 100/% that they are most current and up to date. I'll go grab a link really fast...
Okay idk how you installed adb & fastboot but this guide in my opinion is the best!!! https://forum.xda-developers.com/t/guide-unlock-flash-root-for-the-pixel-2-xl-taimen.3702418/
Try using different ports, reboot your computer..
Did you already have the pop up on your device once connected to computer or no? If not your it won't work at all.
Enable developer options
USB debugging
Now plug in to a different USB port.
Now scroll down on phone to default USB configuration and change it from the default which is "charging" to "file transfer" but keep your eyes on your device screen because the pops up will only show itself for a few seconds. When it does checkmark the box. You should be good then. Windows has driver issues alot of the time!! I switched to Linux years ago and I have no driver issues. Or anything else far as that goes.

Looks like that's not latest. Go here and download latest and install on your computer. See if that helps. Directions in the op of link I pasted in my last post for all OS, Mac, Windows, and Linux.
Type sudo adb devices
What does that do when you are plugged in to pc with phone?
