[Q] My phone bricked. Need help please..

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.
Please help me on this problem. Thanks.

Trouble installing new recovery

Im trying to get my new XOOM from unlock to root and having a nightmare!
I have read and followed guides from the forum but still can't get the new recovery on?
I have done fastboot oem unlock and followed the instructions on the tab and at the end it says complete. Next once it reboots enabled usb debugging and rebooted into bootloader, all ok so far but when I try to run the command "fastboot flash recovery recovery-tiamat-r4c-100611-1150-cwm.img" it comes up with "cannot load"? I have tried with and without the. img at the end and also renamed the file "recovery" and "recovery.img" and still the same thing.
Has anyone had this same problem and can get me back on track please.

if you have adb installed.
copy files from platform tools folder to "tools" folder.
put tiamat recovery image in tools folder.
rename recovery..tiamat as recovery(not recovery.img)
commands:
adb reboot bootloader
fastboot flash recovery recovery.img

Ok, will give it a try when I get to my computer and will report back.

First of all, it really doesn't matter if all your files that you need are in Tools or Platform tools, as long as they are all in there and your command window is operating out of that folder.
Second, you are making a good point re: the img file extension...in Windows, it sometimes is set to hide file extensions, so it is possible that someone could already have the img file extension there and not see it and add it again, making recovery.img.img which of course wouldn't work.
I don't think this is the OP's problem, but you never know.

Error: can not load recovery-Tiamat-R4c-100611-1150-cwm

So I have my Xoom unlocked and I am trying to flash the recovery in order to root. I have the recovery in the platform tools folder along with fastboot and all that, and I'm able to get the Xoom into fastboot from adb, but I can't get the recovery to flash. I'm typing the name correct. And I'm putting in 'fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img' without the quotes. Honestly I'm a little bit stumped at this point.

I used the same guide. It just makes no sense that I can control the Xoom and unlock it, but I can't flash the darn recovery.

I tried moving the files from the tools folder to platform tools still no luck.. all of this for the I C S flash I'm going to keep working on a solution I will let you know if I have any luck!

So I have the android sdk in c:\ , and in the sdk folder I have everything, and in the platform tools I have my fastboot and recovery. I then use cmd to get into adb, then I put the xoom in fastboot. From there I try to flash the recovery, which always fails. I must be doing something wrong here.

Try downloading the IMG again. Or try out the rogue recovery. I actually like rogue better.

I finally got it. In command I needed to direct it to the platform tools folder and then it flashed just fine. I am now rooted. Now to learn about flashing ICS
Thanks for the responses and help guys

Think you have to be stock to flash to ICS, at least that was the word yesterday.
I gave up trying to root just as I found out about the ICS update.

Two simple errors:
1) not opening the command window from the folder where you have fastboot and the image files you're trying to flash; and
2) not realizing that you have hidden file extensions in Windows, and typing ...recovery.img.img

I assume that you've set up a path in environment variables to run adb and fastboot from ay directory... and are running the flash command from a folder other than where your .IMG file is located. In order for fastboot to find the file you're trying to flash, you actually have to run your flash command from the folder your file is located...
So, cd\...\platform-tools and then flash

The simplest way I perform all of my operations for this:
I leave everything installed into it's default locations. I download tiamat's CWM image and place it into the platform-tools folder.
For Windows 7, I use Windows PowerShell.
For example: Open Start Menu > Type "power" to search, "Windows PowerShell" should show up. (For me, its default at the top - so I press enter to open it)
Once opened: I type this configuration EXACTLY as is: (Keys in <>)
Code:
cd C:\Pr <TAB><TAB> An <TAB> An <TAB> Pl <TAB><TAB> <ENTER>
This above brings me directly to:
C:\Program Files (x86)\Android\Android-sdk\Platform-tools\
Of course, this will be different depending upon your computer setup. I've nailed this routine to get to the path the quickest.
to use FASTBOOT (XOOM already in fastboot mode):
Code:
./fastboot flash recovery rec<TAB><ENTER>
This auto completes the filename as ./recovery-tiamat-r4c-xxxx.img
Of course, depending on how many files/folders you have, you may have to hit <TAB> multiple times. I have to do it 3 or 4 times to select the recovery image I want.
Auto-complete is a nice thing. "./" is added to command from the working directory.

This is kinda confusing can u use teamviewer and help me so you

What stage are you in? Have you got clockworkmod-recovery installed?
I assume you are referring to superuser zip file. DO NOT unzip it, copy the zip file into your Nexus S sdcard, any folder.
Copy clockworkmod-recovery image file to C:\Program Files\Android\android-sdk\platform-tools\
1. Reboot into recovery: Power off, hold Vol-Up and long-press Power button. This should get you in FASTBOOT MODE
2. Flash clockworkmod recovery via fastboot: Go into Windows command prompt
Code:
cd C:\Program Files\Android\android-sdk\platform-tools\
fastboot flash recovery recovery-clockwork-5.0.2.0-crespo.img
3. Once fastboot is finished, choose "RECOVERY" option on FASTBOOT menu. That should put you in Clockworkmod Recovery menu.
4. Select "install zip from sdcard"->"choose zip from sdcard" and select the superuser zip file that you copied earlier.
5. Reboot and you should be rooted.
Hope this helps.

OK
So it says sending recovery. But its just stuck on saying that and is it supposed to take long?

If you are on stock rom, clockworkmod recovery may be replaced by stock recovery upon each boot.
You can re-flash clockworkmod recovery each time you need it, or disable the recovery restoration. Search this forum for instruction on how to make recovery stick.

Have you got Android SDK-tools installed? Did you install the "Platform Tools" package via SDK manager? fastboot.exe is not installed by default. You may want to install USB driver too. See attached picture.
Test if fastboot is available and working: plug nexus s to pc:
Code:
cd C:\Program Files\Android\android-sdk\platform-tools\
fastboot devices
If usb driver is working, you should see some device id being displayed.

Acer Predator 8 TWRP 3.0.2

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..

Ok so in "C:\adb" i put all files i downloaded from step 1 then I opened cmd in that folder , then i typed "fastboot flash boot unsecboot.img" and it said that i cant load or open unsecboot.img
Any idea why or where is my mistake ????

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..
