[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.

HOWTO: Root without unlocking the Bootloader

A lot of people have been asking, so here are my notes for gaining root w/o flashing or unlocking the boot loader. :good:
Thanks to Chromium and The Jack of Clubs for their initial concepts and documentation.
Download ADB and set up Tools
Download the full Android SDK here:
http://developer.android.com/sdk/index.html#download
(scroll to the bottom of the page -> DOWNLOAD FOR OTHER PLATFORMS -> SDK Tools Only)
Extract the android-sdk-windows zip to c:\android-sdk
Browse to C:\android-sdk\android-sdk-windows\
Double Click and run SDK Manager.exe
Uncheck everything except the Android SDK Tools and Android SDK Platform-tools
Hit the Install xx Packages button
Download Super SU and TWRP
Download the latest TWRP here:
http://techerrata.com/browse/twrp2/bacon
Extract the TWRP image file and save it as recovery.img in the following folder:
C:\android-sdk\android-sdk-windows\platform-tools
Download SuperSU here: http://download.chainfire.eu/452/SuperSU/UPDATE-SuperSU-v2.02.zip
Plug your phone into your computer and Copy SU zip to the phone... (anywhere will work)
Get your Phone into Fastboot
Reboot the phone in fastboot mode (hold volume up + power). You should get a cyanogen guy smiling at you, this indicates the phone is in fastboot mode.
Open a command prompt and do:
cd C:\android-sdk\android-sdk-windows\platform-tools
Type:
fastboot devices
NOTE: You should receive a list of connected devices, this means your PC is connected to your phone. If not, something is wrong with ADB or your USB driver and you need to fix it before you can proceed!
Boot with TWRP and Flash
If “fastboot devices” worked without error, type this:
fastboot boot recovery.img
After the recovery.img transfers, your phone reboots into TWRP. Hit “Install” and choose the SuperSU.zip from the location on your phone that you saved it to earlier.
Once flashing is done, reboot and enjoy root. No re-imaging or unlocking your bootloader necessary.

if you dont want to wipe data, it also sets flags a tamper bit (which can now be reset), or if you just plain dont want to.

Ah ok, i did unlock and switch to PA after second boot , so there were no data that would be lost

May I ad that there is an easier way to get adb. Its a program called minimal adb. This what I used originally in case someone prefers to just download that file. Just an option thats all... :good:
Nice tutorial

Stuck on Boot Animation

Hi,
I was following this rooting guide...
http://forum.xda-developers.com/oneplus-one/general/guides-bacon-timmaaas-how-to-guides-t2839471
And after I completed Step 2 my phone would no longer boot up. It just hangs while the cyanogenmod bolt logo spins.
I can however now boot into TWRP.
I don't know what to do... I don't think I can copy Super User or Rom Files over to my device currently. I do have an OTG cable with a thumb drive and I plugged it in and I can't seem to access that from within TWRP.
Any help would be appreciated!
Also FYI I'm using Windows 7 for my desktop.

Well, if you have access to twrp, you can do into the advanced setup and select adb sideload. Place the rom in the adb folder and typer: adb sideload 'file'.
Example: adb sideload myrom.zip ; this will flash the rom, which you can then reboot the phone and hopefulyl boot.

Ok so I sideloaded UPDATE-SuperSU-v2.02.zip. Thanks so much for your help!
Should I sideload the stock rom the same way? Will that even work? Should I do some sort of a wipe first?
Sorry if I'm asking too many questions... I just want to be careful.

I also notice if I go into the text pane of TWRP it says
Code:
Updating partition details...
E:Unable to mount '/cache'
E:Unable to mount '/cache'
Full SELinux support is present.
E:Unable to mount '/cache'
E:Unable to mount '/cache'

General rule of thumb, if you want to flash a flashable zip but it isn't on your phone then do adb sideload. All adb sideload does is just put the file onto your phone to flash it.
If you drag and drop the zip onto your phone then u can flash it without adb sideload.
If you're switching from 1 ROM to the next, always wipe. If its the same ROM but you're upgrading to a newer version of the ROM, then just flash without wiping.

Go into TWRP -> mount -> check cache.

Well asking questions is how we learn, so no worries.
You can flash the stock rom / any file in the same manner. When you start with the sideload you can choose to wipe the dalvik / cache.
I would sideload your rom only at this point [stock or custom] and then attempt to boot into the os.
If that fails: from twrp wipe: everything except internal storage, then sideload the rom again; this way you'll be flashing on a clean install.

Ahh success!
Ok if anyone is having this issue here is the solution:
1. Put your phone in fastboot mode (volume up + power)
2. Plug your usb cable in. Go to your PC and open the cmd prompt from the folder on your pc that has fastboot.exe (shift+right click in folder, select open command window here)
3. Type fastboot format cache
4. Then type fastboot reboot
Solved the hanging/boot loop.

ROOT Nextbook Ares 8 with Windows

Update: When you flash the recovery and supersu files make sure to have the remove encryption file on sd card aswell and add it to the list and flash and if you hang at boot screen.. boot into recovery and wipe cache.. reboot.
WINDOWS USERS ONLY.... USE AT YOUR OWN RISK
Make sure you have the proper drivers and make sure you have a real good usb cable... This rar has the usb drivers and the files already in the folder just drop onto desktop and run cmd.exe
Files Needed: http://www.filedropper.com/nocturnaladbfastboot
http://www.filedropper.com/removeencryption
DO NOT FORMAT SYSTEM!!!!!!!!!!!!!
Make sure you are in bootloader or this will not work..
Key combo to get into bootloader or recovery via hard keys.
power off
volume up + power = recovery
volume down + power = bootloader
from bootloader you have several choices to boot, just pres volume down to choose, power to select.
1. To make sure you are connected run command (adb devices) enter
2. Once you see your device run command (adb reboot bootloader) Then..
3. Run command (fastboot boot boot.img) wait for downloading dialog...
4. Then run command (fastboot flash recovery twrp_recovery.img) and make sure you have the proper files on sd card.. i put all files in the folder on my sd card to make sure...
5. once the screen says okay on tablet.. push the vol down button until you see recovery mode and then push power to start twrp recovery..
6. Once in twrp flash SuperSU246.zip and recovery.zip remove_encryption.zip then reboot... you should have root on reboot:good:

Instructions
I think I understand your instructions but I have a few questions.
Am I typing all of the commands on my pc? (- SuperSU)
Step 3 has “Run command “(fastboot boot boot.img)” I see 2 files and so those are two separate commands to run correct?
Step 4 Then run command (fastboot flash recovery twrp_recovery.img) and make sure you have the proper files on sd card.. i put all files in the folder on my sd card to make sure... Again is this 2 commands to run? I see the twrp_recovery.img file but no fastboot flash recovery file?
In step 4 should I be using theses 2 commannds;
fastboot flash boot boot.img
fastboot flash recovery recovery.img

run them just as there posted make sure all files on the sd card and you should be fine..

Thanks for your reply. Those commands are run on the PC in the cmd window right? and I copied the files in the directory to my SD card I installed on the nextbook should that be a problem. Shoul this be the SD card or internal memory? I didn't run the commands the way they were written last night & didn't have success. I am getting hung up on 3. Run command (fastboot boot boot.img) wait for downloading dialog...
My pc and tablet are seeing eachother but they both say waiting, I don't think my files are being seen.

Make sure you uninstall and reinstall the usb drivers in the folder and run the cmd from the folder and if still nothing try a new cable and usb port... when you run command adb devices do you see your listed as numbers and some letters?

After the adv devices command it gives me; listed devices YFGV0815002950 device. That should be the tablet, it’s the only thing attached w/usb & it also shows up in explorer.
After the adb reboot bootloader cmd the tablet reboots into bootloader with “Fastboot CMD WAITING “ at the bottom of the screen.
After the fastboot boot boot.img cmd my pc cmd rompt says <waiting for device> and my tablet stillhas the Fastboot screen mode & FASTBOOT CMD WAITING at the bottom of the screen
That is as far as I get. I copied all of the files in your download link in the .rar format and to a directory on my internal tablet storage. It seems like the tablet is waiting for a file but I don't understand why.

there is a problem after you boot into bootloader i had the same problem for days.. i just played with cables and drivers use the ones inside the folder they worked for me...

I'll keep trying. It has be the drivers.

I followed these directions to a T, but for some reason the device can not read the SD card while in recovery. Any clues as to why this is happening?

So I was online shopping for my first tablet when I came across this thread. . . It led me down to the local WALMART and I picked one up. I successfully completed the process, or so I thought. I went to reboot after flashing everything, and twrp says " no OS installed! Are you sure you want to reboot?"
What did I do wrong?

I have tried several times to download the remove encryption file must be a bad link or something. Is there another download site or can someone send to me plz

Nvm I ran it over with my car because I couldn't get the download link to work. If anyone wants it for parts send me a message. Its brand new only been used maybe 2 weeks. The most wear and tear on it was my Buick regal hitting it at about 45 mph in a pissed off rage. don't think all the insides are smashed tho. Possibly a good fixer upper

Is this fastboot and adb custom versions?
I have adb and fastboot in my path (runable from anywhere)..
ADB says the version release is the same number.
do I need to use your versions for the tablet?

internal card has files that the manufacturer put there,

What am I doing wrong?
Any ideas how to fix?
log says 'unable to find crypto file'
and it couldn't mount /data or /storage filesystems
>>>
installed TWRP3 that allowed the installs although it still
could not open /data. It did find the external card installed
from there.
I am guessing the forced encryption made /data unreadable.
hopefully now with the encryption removed the /data
partition will be readable.
>>>
I reran recovery to check and log now has no failures!!!
I'm guessing the changed boot.img fixed the issues it was having.
*smiles*

cant get files. takes me to a site to sign up. can you dropbox link them please?

I just won this tablet in a contest. Anyone have the remove_encryption.zip file? I managed to find all of the other required files but none of the links in this thread work anymore.

whats the problem with the links? site says free but wants me to pay. losing my head here, and it seems im not the only one

Bad filedropper links
Filedroper no links available, asks us to register and pay for stuff that's not there anymore
can you like put them on Google drive, SendSpace, DropBox, Mega.nz and/or ZippyShare

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..

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

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..
