Have You Lost Root? - Can't find or reinstall su (su binary) ?
Issue:
Your Transformer or other device is unlocked and rooted, you have a custom recovery like ClockworkMod installed and you flash a rom or an update and when done you find you have partial root or no root at all.
Some apps that have previously been granted superuser permission may load while others, including superuser, super su, busybox, Voodoo, CWM say you don't have root, you are missing the su binary file.
When you run Root Checker it might look something like this link.
SOUND FAMILIAR?
Most likely the flashed ROM or update erased the \system\bin\su and system\xbin\su files and didn't replace them.
Since CWM requires the su binary file to get root access to restore from my nandroid I had to use fastboot to get into recovery.I went to my SDK drectory, sub directory platform-tools where fastboot resides..
If you do not have an SDK directory just download SDK installer from [url]http://developer.android.com/sdk/index.html[/url] to C:\android-sdk\platform-tools
Once the SDK Manager comes up put a check in Tools (this will put a checkmark in the two daughter files) Remove any other checkmarks..Hit the Install Packages bar at the bottom.
This platform-tools folder has fastboot.exe command and is the folder you will work from. You can also copy all the files you want to push into this directory but for now we will concentrate on our issue..
Connect your device to your PC, then turn off your device and boot into fastboot mode on your device.
If you don't know how:
hold down volume down and power button until you see white text on the screen, let go both buttons, use the volume down button to switch the highlight to the USB icon (this is fastboot mode), now hit the volume up button twice.
On your PC open command prompt and navigate to the fastboot directory which is C:\android-sdk\platform-tools
Once you there type the following:
fastboot -i 0x0B05 flash recovery recovery.img (check the specific recovery.img file that you have. It could be recovery-jb.img or recovery.blob etc).
Once the process is done type the following:
fastboot -i 0x0B05 reboot
your device will reboot.and can now boot into recovery.
Turn your device off and re-boot into (clockworkmod) CWM recovery
(hold down volume down and power button until you see white text on the screen, let go both buttons, now hit the volume up button twice.)
You want to hit wipe cache partition. When done hit advanced then wipe dalvik cache then go back.
Now hit backup and restore. Once there hit advanced restore from internal sdcard (where you put your nandroid) Then highlight the most recent date
In Advanced Restore hilight Restore system
Once done you can exit out (go back) to reboot system now
Once device boot up find and open superuser app, then download "root checker" from the market and verify that you have root.
RECAP:
Connect device to PC and boot device into fastboot
On your PC open command prompt and cd to C:\android-sdk\platform-tools
type
fastboot -i 0x0B05 flash recovery recovery-jb.img (.img file exactly as it is in platform-tools) hit enter
when process is done, at the prompt type
fastboot -i 0x0B05 reboot (your device will reboot).
Turn your device off and re-boot into CWM recovery and wipe cache and dalvik cache
go to advanced restore and only Restore system
go back to reboot system now
Once device boot up open superuser app, then "root checker" and verify that you have root.
Enjoy
I unlock the g bootloader got it to root I have the latest cwm recovery been trying different ones also, but some how when I try to install any rom that's out there it won't boot up it only stays on the boot screen . Any ideas
Me too
I have this problem too.
Guys, please search the forum before posting, so your issues would get resolved quickly.
OK, Now towards your problem.
A lot of people are getting the same error and the results from corruptioning of /data. First try factory reset from fastboot, then reboot. If it doesn't help then do a factory reset again and reboot your phone. If doesn't seen to help either then the only option left is to flash stock firmware through PC. Search the forum and you will get the desired result. Beaware that you will end up losing all your apps and SD card data.

So here's a detailed instruction for you to follow.
1. In fast boot mode connect phone to PC.
2. In CMD (adb) in PC type the command "fastboot devices" without quotes and post the reply to me.
3. In the CMD, type the command "adb erase userdata","adb erase cache" without quotes. (It will wipe all your data and SD card)
4. Now download the firmware (new firmware download it in case there may be issues with the old one you have downloaded) and also TWRP-2.7.0.0.falcon by dhacker. Copy both the files in the adb folder.
5. Rename the twrp-2.7.0.0.falcon.IMG to recovery.img
6. Connect your phone to PC in fastboot mode and flash the recovery by topping command "fastboot flash recovery recovery.img"without quotes.
7. On your phone scroll to recovery option and long press volume up key until the phone vibrates. The phone will boot into recovery.
8. In recovery goto advanced-file manager. And check whether your /datafilleris empty or not (it will be empty)
9. In recovery go to wipe and wipe /system /data /cache. Next reboot your phone to boot loader mode.
10. Flash any firmware from your PC through fastboot. Then reboot your phone.
If it doesn't help either reply to me, there's other workaround too.

This is the same thing a friend told me to do we did it had no luck Did it 2 times just in case I dint do it right the first time
Moto g not booting up.
I hope you have an unlocked boot loader.
The first thing you need to find out is that are your phone's partition writable and readable.
1. Download the latest CM11 nightly to your PC rename it to "CM.zip" and extract the contents to adb folder (adb folder should be in C drive i.e. C:/adb ). You will get boot. img , system (folder), and others.
1. connect your phone to PC in fastboot mode.
2.In adb type the below commands one by one without quotes. And let one command get processed before typing other.
"fastboot devices" (in response it must show you something like TJ9*****)
"fastboot erase userdata"
"fastboot erase cache"
"fastboot push C:/adb\system /system/"
"fastboot flash boot boot.img"
"fastboot flash recovery recovery.img"(flash the philz recovery now)
"fastboot push C:/adb\boot.img /data/"(to verify whether /data is writable or not)
"fastboot push C:/adb\boot.img /cache/"(to verify whether /cache is writable or not)
"fastboot push C:/adb\CM.zip /data/media/0/"(to push the CM11rom to sdcard to flash it through recovery)
Then boot your phone to recovery. And see the logs, it should show
/system mounted
/data mounted
/sd-ext error mounting /sd-ext
/cache mounted
If it shows /data can't be mounted or error mounting /data. Then go to wipe and wipe /data and /sdcard and then again push CM.zip to /data/media/0/. If you don't see this error, then choose to wipe to install a new rom. After this remount /system /data /cache and flash the CM11.zip or you can flash stock firmware through mfastboot.
This method will definitely work since I, myself had this very same issue and got it resolved the very same way.
P.S. Try this method and only of you get some error then reply as I an sure it will solve your issue.

Hi forgotter! I have the same problem... won't boot with any ROM. I've followed your instructions but stil stucked on the boot logo. I will try the second method you provided now, hope that works :crying:

Didn't know why first method didn't worked for you but the second one would definitely work. If you get any error then reply to me, and yes in my second method post by mistake there are some extra space added after full stop (.) e.g. in boot. img (it is boot.img ) do please avoid that.

Don't worry your phone is fine.
Whenever adb shows m mismatched partition it's fine and usual.
I understand your problem now, I just think if I your device now , I would have repaired it within minutes. Never mind, follow the below steps .
Download the philz recovery to your PC, flash it through fastboot on your phone. Then go to recovery on your phone immediately and choose wipe-wipe data and sdcard. And then flash the stock firmware through mfastboot or install any ROM through recovery.
Anyone report which step what must i do to solve this prob

Read post #7 on page 1.
I cant push system to device. What tools must be i have?
If you can't push system to device don't worry , it's of no use at all because you'll format it before flashing the rom. But if you're flashing through recovery then make sure to push CM. zip to /sdcard/.
You need adb tools on your PC, just search Google for adb tools and download it. You need stock firmware of your phone on PC if you'd flash the rom through mfastboot and you need philz recovery ( to flash it on your phone.)
If you can't get anything or don't understand anything then do search the forum for help because all the things are already mentioned and if i had to answer it mostly would be copy-paste. But still if you need help, I am there. Just post your problem.

I'm having similar issues as everyone else here. I unlocked my bootloader following Motorola's instructions on their website, then I used Superboot to root the phone (which I don't think worked as CWM and TWRP kept asking to install SU on reboot). After that I put CM 11 M4 on sdcard and flashed.
This is where it went wrong. I rebooted and got a bootloop, so I looked around online and ended up wiping everything and trying again. It still didn't work so I followed instructions to reflash stock firmware, this didn't work either. By this time the phone had been on ages and went dead. Now it won't turn back on and won't register as charging from USB or from wall plug.
I have no idea what to do as nothing worked before hand and now I can't access it to resolve the issue.
I'm panicking atm because I'm contracted to Virgin Mobile in the UK and this voids the warranty. I just don't know what to do D:

Plug the phone to wall charger and leave it to charge for the whole night, the next when you'd restart the phone it should boot up. Sometimes the phone discharged itself to such a level that it didn't have enough juice left to show the battery charging status even.
After that follow instructions from post #7 on page 1 and paste all output commands you see. Well, the phone should boot up.

Mismatched partition size is usual , no need to worry about that. What do you mean by UBL warning message? And yes, after you flash recovery, enter in recovery mode and wipe data and sdcard and then flash any ROM from fastboot.
And if you get into an error or solution doesn't work then post your problem but detailed so I can get to the main cause of the problem.
so i factory wiped out everything by accident... phone is stuck on team win recovery project... and connects to the computer but only charges... i have no way of putting rom on a storage... am i ****ed? any help would be appreicated...
See if you can boot into fastboot. Then you can simply put the stock image back on.
Hello,
Use the following steps to sideload a rom:
1. Head over to TWRP and perform a data/cache/dalvic wipe.
2. Copy the rom.zip and gapps.zip to the fastboot folder in your computer.
3. In the recovery, go to advanced and select adb sideload and swipe to the right.
4. Now open cmd window from the fastboot folder and run the following:
Code:
adb sideload rom.zip
5. After it's done do the same with gapps.zip.
6. Reboot!
If you don't want to use a custom rom then you can flash the factory images from here : https://developers.google.com/android/nexus/images#hammerheadkot49h
For the steps, follow this guide: http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
Hello,
I have the TF300T and installed twrp 2.5 and the android 5.0 rom. After a some time my TF300T became slow so I went in twrp and did a advanced wipe.
After that I wanted to install the again the rom but I got errors, so I did a reboot and now I have nothing expert the Teamwin logo that keeps booting.
I think the file format of the system is corrupted. Any Idea what I can try? The WIPE in the start menu when you power on the device with power down key I see the 3 logo's.
SOLVED: thanks to fastboot I installed the stock firmware. All works fine now.
Im again in TWRP thanks to fastboot
Code:
1) to have the correct driver for fastboot you can install asus PC sync from the asus website
2)download fastboot from internet and extract to c:\fastboot\
3)download from goo.im openrecovery-twrp-2.4.4.0-tf300t-4.2.blob and put in the fastboot directory
4)boot the tf300t holding power + volume down and connect at the pc
5)open command prompt (run cmd.exe) and navigate to c:\fastboot\
6) to know if the device is connected correctly use the command "fastboot devices" it should show you a string with numbers and letters
7)to install the recovery use the command fastboot -i 0x0B05 flash recovery openrecovery-twrp-2.4.4.0-tf300t-4.2.blob
8)Reboot with the command fastboot -i 0x0B05 reboot-bootloader
Now the big problem that I have is that it cannot mount the /data, /system, ...
Any help would be welcome
My Android phone (Motorola Edge) can no longer start properly after a failed system update. The message I get is: "Cannot load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device."
I've tried restarting it in recovery mode which didn't work. I've read that I may be able to install some software via USB and rescue the system but I have no idea how that's done. I've looked at some different rescue software such as Rescue and Smart Assistant (which would only let me rescue the phone which will erase all data) and Dr.Fone but the reviews aren't convincing and the unofficial software programs generally don't support Motorola phones. Does anyone know how to fix my phone without losing my data?? Any help is much appreciated.
Also; I'm in no way a developer so I need everything explained to me like I'm 12 years old.
hi, kid welcome to xda.
now about your problem, it is very simple.
1) download latest firmware according to your country.
2) boot the phone into recovery mode.
3) if you have windows on pc then install minimal adb and fast boot from this Link
4) connect your phone to pc using adb cable ( the cable in charger )
5)open command prompt type adb devices
6) if you see any thing like 213547448882 recovery ( recovery should be displayed)
7) type adb reboot bootloader
secondly unzip the downloaded firmware you will see many files with .img extension
8) type fastboot erase system
9) type fastboot flash system <----- here don't type system rather drag and drop file in cmd for location of file
10) if result is success then you must boot normally without data lose.

Thank you so much for your input. Unfortunately I can't make it work. When I type 'adb devices', I get this text:
List of devices attached
ZY227HQ2BX sideload
I've attached more info. Not sure if this has something to do with "USB debugging"?
all things right,
that sideload appears because you have stock recovery {no need to worry}
you don't need to erase system, (it is like optional)
and the error ANDROID_PRODUCT_OUT....... is because as i said earlier you have to copy the path of the file not file name.
how to copy path of the file ?
well, simple on windows, open the folder in which system file is present. and again open command prompt type (remember to be in fastboot mode in mobile phone)
fastboot flash {drag and drop system file from folder to command prompt}.
it should look like (but not the same, it is an example)
fastboot flash E:/newfolder/nexus/files/system.img
tell me if you face any problem (also include screenshots like you did, great right?)
What file is the system file in this folder?

Hi again, I've spent all weekend trying to figure it out but so far no luck.
I don't know where to find the system file in the folder I downloader (see attached photo in my reply above this). I also tried making a service-batfile with guidance from YouTube but it seems my phone is locked so it doesn't work.
well sorry i was quite busy so i was not able to reply.
first thing first do you need your data
if so boot into twrp. find twrp image for your phone then use command in fastbootmode
fastboot boot and drag and drop twrp file.
after successfully booting into twrp use option to backup and backup your data in any external storage like sd card.
after that run flash all.bat inside your downloaded folder.
i will completely wipe and reinstall your firmware.
then after it again in fastboot mode boot into twrp and restore your backup that's it.

Will unlocking the device delete my data?

What about your original suggestions - will they not work on a locked device? Fx this:
now about your problem, it is very simple.
1) download latest firmware according to your country.
2) boot the phone into recovery mode.
3) if you have windows on pc then install minimal adb and fast boot from this Link
4) connect your phone to pc using adb cable ( the cable in charger )
5)open command prompt type adb devices
6) if you see any thing like 213547448882 recovery ( recovery should be displayed)
7) type adb reboot bootloader
secondly unzip the downloaded firmware you will see many files with .img extension
8) type fastboot erase system
9) type fastboot flash system <----- here don't type system rather drag and drop file in cmd for location of file
10) if result is success then you must boot normally without data lose.
