My phone is unlocked and rooted. My problem is that when I go to FASTBOOT MODE, then go into RECOVERY, then when I press 'apply update from /sdcard' it shows nothing in there. So, I just stuck and unable to flash any rom at all. I tried to go into the SD card through my computer to install a ROM so that I have something to flash, but nexus s has only internal storage. Please help?
Hi
Hi, I bought my nexus s, immediately after I tried to root, and failed, this left me in the same situation as you.
You NEED to install the adb drivers, and boot using odin files. It was pretty tricky but i got there in the end, i was bricking it too , but dont worry, there's a 98% chance its not bricked, ill find the files for you now...
Go to mount drives and mount your storage from there. That's what I did.
Right, first of all, boot into the bootloader on your Nexus S, and i'm assuming that all your drivers are working fine because you have already unlocked your bootloader.
Place the files in the zip download inthe following places
WIN32bitOS: Program files/Android/Android-sdk/tools
WIN64bitOS: Program files (x86)/Android/Android-sdk/tools
Next, open a command prompt, and type in the following commands, (C: is your windows installation hard drive letter, leave as default if you dont know what this means)
if your 32bit type this w/o quotes "cd C:/Program files/Android/Android-sdk/tools
64bit "cd C:/Program files (x86)/Android/Android-sdk/tools
and click enter.
Next you want to make sure that your Nexus S is in bootloader mode, connected to your pc.
Type the following.
fastboot flash boot boot.img
[click enter & wait until it says successful]
fastboot flash recovery recovery.img
[click enter & wait until it says successful]
fastboot flash system system.img
[click enter & wait until it says successful]
fastboot flash userdata userdata.img
[click enter & wait until it says successful]
Reboot and you should go into android 2.3
Next time make a nandroid backup in clockwork mod!

hi cdaly, can you point me to some information on how to install nandriod backup and making/restore a backup right after installing CWM (right after "unlocked" but didnt install Super user yet)?
Yeah
Yeah sure,
Root your phone, go to market place, download rom manager. Open the app and click the button that says, Fash Clockwork Recovery.
Shut down your phone when the operation has completed. Go inot bootloader mode, click recovery. Navigate to backup and restore. Go into backup and restore, click backup. Voila.
If you ever need to restore do the same but click restore. Pretty simple when you know what to do
If this has left you confused, look around on XDA/google, there are a ton of guides
Link added!
Thanks, appreciate it.
Thanks for that. I am using mac computer. Would it be the same typing command for mac as you had mentioned?

Thanks very much cdaly.. I am just a bit confused regarding phone is rooted or not.
I got to the point flash recovery was sucessfuly in command prompt, but when i try to install "su-2.3.6.1-cd-signed.zip" from SD card, it wasn't successful, as in there is no "superuser" icon after reboot and i have tried wifi tether and it says my phone is not root.
Now i havent tried "su-2.3.6.1-ef-signed.zip" because i accidently bricked my phone for some stupid things i did. but my phone is NOT root as long as I don't see the superuser program right?
I thought nandroid is an actual program but it just means backing up through bootloader?
Thanks for all your help!!!

I dont know if NANDROID is a program or not, it just use it via clockwork mod recovery menu and it works so I'm not complaining aha
If you want to root your nexus s, download this zip file and extract, make sure that your nexus s is in bootloader mode and double click "install-superboot-windows" Bingo, you have root.
Thanks for that. I am using mac computer. Would it be the same typing command for mac as you had mentioned?

It wouldn't hurt to try but I dont think so. If you can go into boot-camp or use a friends PC. Or you can try this.
Change your folder to the plaform-tools folder. I dont know how to do this, just referencing off of http://rootzwiki.com/wiki/index.php/Samsung_Nexus_S
Next type
"./fastboot flash boot boot.img"
"./fastboot flash recovery recovery.img"
"./fastboot flash system system.img"
"./fastboot flash userdata userdata.img"
Hi cdaly985
I'd tried it and it works 100%. And, just to share for mac to add on the command "./fastboot-mac ....". I am really impressed with your help. Thanks very very very much.
Hi cdaly985
Now everything is ok with the phone except that it won't be able to go into recovery mode. I had tried by using Rom manager v.4.. and also by pressing vol + power, all failed.

If you have the SDK installed on your computer. Here is what you need to do in order to get back into recovery.
#1 Boot your phone into bootloader, Vol up and power
-Plug into computer using usb while in fastboot(bootloader) and see if it recognizes it. Type adb devices it should list a serial number for your device.
( My SDK is installed in c:\android\) so you would type something like cd c:\android\tools and hit enter and then type adb devices )
#2 If you have installed sdk and pdanet drivers and your computer still does not see your phone in fastboot is this. Go to the folder where sdk is installed and copy everything excluding the folders that is in the Platform-tools folder into the tools folder. After that download Stock Phone files unzip it into a folder on desktop.
Dont run the script yet, what you have to do is after you unzip the stock look in the folder you just unzipped them in and you should see a file called fastboot, adb, and some other .dll's AdbWinApi.dll and etc move only these 4 files to your sdk tools folder.
#3 Now re open a cmd prompt and go back to c:\android\tools (enter) then type in adb devices and your computer should recognize it this time around.
Then all there is left to do is download the recovery of your choice here's mine Recovery and after you download it rename it recovery. After you rename it move it to sdk tools folder and while still in fastboot(bootloader) type in fastboot flash recovery recovery.img
You should now be able to enter recovery and flash roms again
EDIT #1
If you havent setup SDK here is a wiki guide on how to do so http://wiki.cyanogenmod.com/wiki/Howto:_Install_the_Android_SDK
Make sure you are using the most up to date drivers and then use ADB to install recovery again. If I'm understanding it right I think that's what you need to try.

Ok I don't know if you tried this already but do this:
1. download the recovery img from here:
http://wiki.cyanogenmod.com/wiki/Ne...de#Installing_the_ClockworkMod_Recovery_Image
and put it somewhere on ur computer
2. plug phone into comp
3. boot the phone into the fastboot mode with the android guy
4. fastboot erase recovery
5. fastboot flash recovery ____.img
and if you can boot into recovery now, just wipe data, cache, and dalvik cache and flash the ics rom
see if that helps

I suggested this about 7 hours and 3 threads ago.. I think the problem is either he doesn't have the proper drivers or SDK setup properly.

This leads me to believe that SDK isn't set up properly. If it's set up correct you should be able to access adb without the phone even connected.
Yes thank you guys i love u all

this tutorial, is for repairing the huawei g750-u10 in case you flashed the wrong recovery and now you're stuck in a bootloop.
First of all you will need (it's all in the link to download, make shure you have a sdcard on your phone before starting):
-Adb install setup
-Adb toolkit
-vcom drivers
mega.co.nz/#!gURHXDoZ!QNmv7LaK8r4WIQBGaUyoNho3TPX0YZp9jwHaEHgDmII
note:the recovery.img provided on the rar file only works for the U10, the method might work for other models but with a diferent recovery file.
-Installation of the phone mediatek drivers:
-Start with installing th vcom drivers i provided on the rar file, type HDWWIZ on the windows search tab:
Install the hardware manually>Ports(com&lpt)>Have a disk>select the file wich corresponds to you windows>mediatekpreloader usb vcom port> restart your computer. (if this method doesn't work for you try to search for vcom driver installation tutorials)
-Installing adb
-double click on the adb-setup.exe file provided and install it including drivers.
-the adb tool kit doesn't need installation just run the Adb toolkit Gui
on adb toolkit, type the command fastboot continue as shown in the picture
s13.postimg.org/yuauaawpj/Untitled.jpg
Remove the battery from your mobile phone, wait 5s plug it in again. Connect the usb to the computer and pluh it to your phone and at the same time push the power button till it turns on but keep your finger in the VOLUME DOWN all the time, it may reboot 2 times but then you will get the fastboot/repair mode image you can now lift your finger.
When you are in fastboot connected to your computer (the mediatek drivers will install wait for installation to complete).
Now return to the Adb GUI and press the execute command, (it will appear 3 lines starting with something saying error dont mind that it's normal) and wait a few seconds then your phone will restart it self and boot normally.
You're allmost there:
-When your phone boots, select the usb connection to usb mass storage device.
-copy the recovery.img provided to the root of your sdcard, safely unplug the phone from your pc.
-download and install the mobile mtk uncle tools app from the playstore.
-turn off wifi and mobile data, start the app and give it root permission.
-press the recovery update, select the chinese character file that you copied to your sd before and proceed, VERY IMPORTANT when it asks if you want to reboot into recovery select NO.
- get out off the app and restart your device normally, it's all done you have your phone back.
this is my first tutorial on xda, hope it is easy to follow and i'm thankfull for any suggestions to improve it.

Hi, I've followed the instructions you gave and now I'm stucked at the part which it wouldn't reboot by itself after i typed the "fastboot command".
1) Before I've had chance to charge my phone, it ran out of battery and fastboot mode does not charge the phone. I've also tried to flash the recovery image in fastboot mode, but i got Err:0x2017, what is this error about?
2) And the GUI should run in location bin files as my fastboot driver, not the 0KB fastboot in default location.
2) Do all these steps require unlocking bootloader? I don't think I've unlocked, all I did was just root the phone.

Hi
I have a rooted Huawei Ascend Mate but I installed the wrong TWRP recovery a few days ago. My phone keeps booting and I can't use my recovery, because it is a touch version but it doesn't respond to my touch. So, I don't know if I can flash my stock rom or another recovery...
Can I use this tutorial to fix my phone or can you please make one for the Huawei Ascend Mate?
kind regards
TWRP 3.0.2 for Acer Predator 8 ported by Ruben. - If you like my work please donate here, it will also give me a boost to make more things for this device : https://www.paypal.me/RubenCraveiro
----------- -----------
IMPORTANT NOTE ABOUT ROOTING AND UNLOCKING BOOTLOADER:
After flashing TWRP 3.0.2, use the SuperSU 2.46 flashable zip, do NOT use latest version or will result in a bootloop. Good Luck and have fun with rooting. Unlocking bootloader will delete all your data, so please make a backup first. Thank you.
----------- -----------
CREDITS
And also, before anything i would like to say thanks to @arjaylzo for telling me the name of a device with TWRP which helped making this update possible.
REQUIREMENTS
1- Fastboot/ADB Drivers and ADB folder
For drivers: http://adbdriver.com - Download ADB Driver Installer (universal) from the website, extract it, connect device it should detect device(if not, enable USB Debugging and reconnect), and press install, it should install drivers.
For ADB Folder: download this and extract to your main drive(C:/): https://goo.gl/ZTrfBb
2- Unlocked Bootloader (you need requirement 1 to do this)
Instructions for Unlocking bootloader: Go on settings, about device, press build version several times till it says your a developer, go back to settings, press Developer Options, and enable OEM Unlocking. Power off, then press at same time Power and Vol+ button, then connect to pc and open a cmd and write cd c:\\adb and write fastboot oem unlock, then accept the prompt it will give on tablet, and follow the rest of the steps.
----------- -----------
New TWRP bugfix update! Now you can flash stock rom on TWRP without bricking! Download Page updated!
----------- -----------
BUGS:
1- adb shell command needs to be sent before system partition is mounted or it will give an error, after doing adb shell you can mount system and do all the modifications you need.
2- You cant flash any img on twrp it gives an error, im trying to fix.
3- Backups do work, but everytime twrp restarts, the device name seems to change (which means that on /TWRP/BACKUPS/devicename/backupsinside/ changes every reboot so you have to go get the backup inside the old devicename folder and put on the new devicename folder).
----------- ADITIONAL NOTES -----------
Im leaving an unsecured boot image because system seems not want to boot android if anything seems changed. So please if system does not boot after flashing twrp/rooting, flash the unsecured boot img on fastboot
----------- -----------
Steps TO INSTALL TWRP AND ROOT
1. Download and extract the files: https://drive.google.com/file/d/0BxzG5iupOOSKNTdlRC1Wd0VmTlk/view?usp=drivesdk
2. Power off the tablet.
3. Enter fastboot mode by pressing the power button while holding down Vol -
4. Open up command prompt and navigate to the directory where fastboot.exe is located.
5. Pass the following commands:
fastboot flash boot unsecuredboot.img
fastboot flash recovery TWRP.img
6. Reboot into recovery (TWRP) and install SuperSU v2.46.zip

C:\adb is where my adb and fastboot commands are.. on the downloaded files from Step 1 only the SuperSU zip is needed on the tablet so that you can flash it later on with twrp, the rest you leave on pc and use fastboot to flash TWRP, unsecured boot image, etc...

make sure you didnt put a folder inside the adb folder instead of the actual file and make sure your writing the right name of the file..

also its not unsecboot, the name i added on this thread was just so it would be faster, the name is unsecuredboot.img and not unsecboot.img i guess ill have to edit that in order for people following the tutorial by line dont make these mistakes..

If you flash stock rom, i think you have to reinstall stock recovery, the rom itself already brings stock boot.. after flashing stock recovery it should boot since no modifications have happend
Wow good job! Now i have a recovery where i can flash my custom rom for the Predator 8.

On step 4 You need the fastboot files, (adb & fastboot) just search how to install adb and fastboot drivers, choose the directory where to install them and place the needed files inside that folder and open a command prompt on that folder so you can flash the files.

ir I tried finding how to install fastboot driver on Google all showed me downloads links must do survey or download or purchase item to unlock the download files ... So I don't trust it so I kept searching "how to unlock fastboot Acer predator 8"
So for ADB I can search on Google and install it on my tablet ?

no, Search how to unlock bootloader, it should show the method that works for most devices and give necessary drivers..

Yes, and after you unlock the bootloader, you put the necessary files in adb folder and flash them according to the stepts
Ruben Craveiro said:
C:\adb is where my adb and fastboot commands are.. on the downloaded files from Step 1 only the SuperSU zip is needed on the tablet so that you can flash it later on with twrp, the rest you leave on pc and use fastboot to flash TWRP, unsecured boot image, etc...

That means adb drivers arent corrently installed, but i can see you have the folder with adb, all you have to now is download this(drivers): http://dl.adbdriver.com/upload/adbdriver.zip
Extract and open the software eith the tablet plugged in, it should tell of drivers is installer properly or not, and if not you can install, after installing it should work on the cmd the commands..
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.

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 )
