[HOWTO] Revive a bricked P500 on fastboot mode (the SHORT way)

The usual DISCLAIMER: Use at your own risk!
Fastboot mode usually comes up if something went wrong when trying to flash a recovery image, for example when flashing AmonRa recovery or ClockWorkMod. It happened to me several times so I tried to learn to revive it without reflashing the original firmware. Note: This tutorial works only if recovery is the only one broken. (If the ROM itself is broken, then that's a subject for another tut.) In this case, the most logical thing to do is just reflash the recovery image. So how do you do it in fastboot mode? Here's how:
Symptom
You tried flashing a custom recovery like ClockWorkMod or Thunderg, or you flashed an incorrect ROM, and when you rebooted, it showed this screen:
Code:
fastboot mode started
udc_start()
and the phone stays there. When you plugin the phone to your computer's USB, it is detected and the screen has this display:
Code:
fastboot mode started
udc.start()
-- suspend --
-- reset --
-- portchange --
-- reset --
-- portchange --
You will need
1) Your PC and your USB cable for the phone
2) USB drivers for your phone (use B2C from LG).
3) Android SDK (download from here)
4) Java, required to run the SDK (but right now I am not sure if this is required to run fastboot!)
5) ClockWorkMod or AmonRa Recovery.
Here's what to do
1) Assuming phone is turned on in fastboot mode, plug it in to the USB of your PC. You will know that it is detected if you see the the lines "suspend", "reset" and whatnot on the phone's screen.
2) Extract the recovery image from the zipfile downloaded from step#5 above (e.g. LGp500-recovery-v12.img). Place the image file in the same folder where fastboot.exe is (usually in the tools\ folder in the SDK). For your convenience, rename the img file as recovery.img
3) Fire up your command prompt and cd to the directory where fastboot.exe is located. Then type the following command:
Code:
fastboot erase recovery
Once you get the confirmation that it was successful, type this:
Code:
fastboot flash recovery recovery.img
Once you get the success confirmation, reboot the phone, or you can also type (optional):
Code:
fastboot reboot
The phone will reboot itself, and with any luck you should be able to go back to your same old Android bootscreen. Note that no settings were modified here, so this is extremely useful for those who do not want a clean slate after a fastboot nightmare.
Also, note that if this is successful, you can now boot to recovery with the usual button-combos, thus enabling you to flash ROMs and other recovery zips.
Note: On some SDK versions, fastboot may not be included. For your convenience, I have attached the fastboot binary I got from my downloaded SDK. I have also attached AdbWinApi.dll which some user reported is missing in the SDK. Place the DLL in the same folder where fastboot.exe is located.
Questions, just drop me a line here

thanks dude, its very usefull

Nice tutorial for newbies like me, thanks...

We already have a tut like this.

@arvinoids
Good tutorial, but you forgot to say that LG USB drivers are needed and that fastboot.exe must be downloaded before (it's no more included in android SDK)
thanks man

You are right! I should add that here. Also, I got the latest SDK to verify and found fastboot.exe under the "tools" folder. Can tell me which SDK version you downloaded?

Usefull, thank you

Wow, that's strange. I have r11 and it is included there. For your convenience, I have attached the fastboot.exe from r11 on the first post. Thanks for trying this out.

i have a question... if we don't see the fastboot line on our breaked phone and we see just stuck at LG Logo and the Recovery is broken too, what we can do?! how we can enter in fastboot mode in this situation?

hey
I run the CMD
executed cd command but the next command
"fastboot erase recovery"
gives the following error ( see the image)
Please help

@arvinoids:- mate your work acted as a GOD to me for now. I solved my above issue by just googling the AdbWinApi.dll, downloading it and putting it in the same directory as the fastboot.exe
Thanks mate

Hi. Sorry I was away for the weekend and just got back. Thanks for reporting this. I just did a search on my desktop and found out that AdbWinApi.dll is included in the platform-tools package. I will add the instructions to download the package from the SDK. I'm glad you were able to revive your phone. Thanks again!

I'm afraid your issue may not be a subject for this tutorial. Fastboot mode is activated when the phone's recovery image is broken. May I know how you are sure that the recovery is actually broken?

[Q] Serious problem

Hi,
please help me! I hope it is not a brick.
I wanted to make full wipe. I made factory reset in recovery and then wiped sdcard.. Now I cannot boot ROM because there is no one and I have nothing on my SD. So I even cannot copy rom or backup back to phone.
Is there any way out? (
EDIT: I think I can push files (e.g. backup) through adb, right? I installed adb for dummies but when I want to execute SDKmanager.exe. it only opens black window and immediately closes it. I cannot continue

Access your commands through a terminal window, like start > run > cmd to get into the prompt.
and from there work your way to your directory where you have placed it, and execute the command from that directory directly.

..

Thanks!
In the end I used adb to push backup in recovery...
All this I did because I wanted wipe my device - today I woke up and got a call and found out that my earphone stopped working I am afraid that it is due to condensation and next oxidation... I did not do anything wrong but when you come from cold winter weather into a warm flat it can happen Now I need to send it and hope the warranty will pass..
Anyway, I was looking for complete unroot process and found several advices. I am not clever from them. Is it enough to flash stock ROM? Recovery will be removed as well??

1.Switch off your phone
2.Connect your phone to your PC throught the USB cable
3.Switch on phone into fastboot
4.Provided that you have the driver for windows for the phone installed open Start/run/cmd (from your PC)
5.From the Android-SDK/platform-tools run the following "fastboot oem lock".
like :
C:\Android-sdk\platform-tools\fastboot oem lock
this will lock it immediately ...

it works only in "tools" and then it just says "waiting for device" and stucks When I tried "fastboot devices" it says nothing... I tried to reinstall drivers but maybe I have some old version? When I am in Windows copying files etc. it works well.

1. Make sure you open the command prompt IN in the folder with fastboot.exe.
2. Put the phone in fastboot mode.
3. In the command prompt type fastboot devices.
It will now show your serial number. If not its either you are such a noob that you managed to screw that up or the fastboot drivers are not installed. Or both.

If you have i9023 you need to add a line into the sdk for driver. You can search the tutorial threads for it.

try this
just check if you have fastboot and adb on the same folder, when I've rooted mine's got this issue, if cmd report "the command is an external one" simply means there is no such program in the folder you are in
copy both adb and fastboot in tools and platform-tools too, so you can run the command in both folder
cd>desktop > cd android>cd android-sdk> cd tools (then run adb or fastboot)
cd>desktop > cd android>cd android_sdk> cd platform-tools (thr run adb or fastboot)

1. Find out exactly what phone model you have if you don't know already.
2. Do the same for your computers os . Including 32 or 64 bit.
3. Combine that info and search the forum or just Google search. How to install fastboot drivers for phone model in step 1 with the os in step 2.

Thank you all. I decided to unroot it and relock it using Odin software which was great and quick. So I am done.... Adb has a lot of problems with drivers, commands, paths. This way was much easier

[ROOT] Acer Iconia Tab A110 (All Things Root)

After lots of hard work by a great team of people (listed at the end), we have finally made a working Root for the Acer Iconia Tab A110.
Warning:
Code:
*I, nor any of the people involved in the rooting process of this
tablet are responsible for any damage you may cause to your device.
*If you brick your device, we are not to blame.
*Your warranty may be void after doing this.
*By using this guide, you acknowledge that you are fully responsible
for any damage you cause to your device and the device accessories.
ACER ICONIA TAB A110 ROOT GUIDE 4.1.2
UPDATED NOVEMBER 13, 2013; Most Recent Version​
You will need to download/install the following before starting:
Acer Iconia Tab A110 USB Drivers (Should install on first connect of tablet)
Android SDK
SuperSU
a110-412-CWM-recovery.img Mirror: a110-412-CWM-recovery.img mirror
___________________________________________________________________________
Once downloaded, extract the Android SDK to a known location, such as the Desktop. (Use an extracting application such as Winrar)
Next, install the Nexus 7 Toolkit.
___________________________________________________________________________
Once that is complete, you can begin the rooting process.
On your device go to:
Code:
Settings > Developer Option
Turn Developer Options on at the top, and enable USB debugging.
Navigate to your Android SDK folder:
Code:
adt-bundle-windows-x86_x64\sdk\platform-tools
Copy and paste the recovery file in this directory, and copy the SuperSU files to the Tablet's SD Card. This will make the process easier later.
___________________________________________________________________________
Bootloader unlock:
The next step will wipe all your data. Remember to create a backup of anything you want to keep before attempting this.
Open a command promt (CMD) window in the directory above by holding shift while right clicking in the window and selecting "Open Command Window Here."
Type in CMD:
Code:
adb devices
Code:
adb reboot bootloader
Wait for the tablet to load into the bootloader, then type:
Code:
fastboot oem unlock
Accept on the tablet via volume and power buttons.
Your bootloader should now be unlocked.
___________________________________________________________________________
Root:
Type:
Code:
fastboot reboot-bootloader
Wait for it to reboot, once again.
Next, type:
Code:
fastboot devices
Code:
fastboot boot a110-412-CWM-recovery.img
Wait for the "OK" notification.
___________________________________________________________________________
Now, you will be booted into the custom recovery.
Right click on the Acer A110, and select install driver. Choose to point to your own path, and point it at the path for the Nexus 7 Toolkit install. (Make sure you have include subfolders checked)
Now, the device should be recognized and the root can continue.[/Code]
___________________________________________________________________________
On the device, use the volume buttons to navigate and power button to choose.
Select Install from SD.
Now type:
Navigate to the CWM-SuperSU-v0.99.zip file.
You should receive a complete message.
Once that is complete, on the tablet, navigate to reboot, select yes at the prompt, and the tablet will reboot.
You are now successfully rooted on 4.1.2!

Stock Recovery
Here is a link to the Stock recovery pulled off of my tablet.
Not sure if it works or not, but if someone wants to try:
Stock Recovery
Installing Applications/Games to the External SD Card
I spent a long time looking for a program that allows me to do this, and finally found one that fully works.
DirectoryBind works wonders.

There is currently no way to make a full nandroid. However, if you want to back up the contents such as apps and data, use an app like my backup pro or titanium backup.
Make sure that it saves on external SD, not internal or you'll lose everything.

How did you try unlocking the bootloader?

after you type "fastboot oem unlock" look at your tab and use the buttons to select it. It gives you about 10 seconds until it reboots back to the bootloader
Oh and I can't get the sideload to kick in. I put in "CWM-SuperSU-v0.99.zip" but it doesn't do anything.
Im wondering if I can push it over using adb install bc adb sideload isn't working?
Thanks

Install the google drivers... I do the sideload of su and it looks like works.... but not root... I am not sure why... Everything looks good... I am unlocked... the recovery image loads well...

Exactly the same results as the previous guys, every step appears successful, including sideload, but no SU after reboot. My Firmware has WW in name.

Anyone any idea what may be wrong?

Wiped EVERYTHING by Mistake NEED HELP

Accidentally wiped everything using TWRP and have no OS now. Can't use ADB or fastboot as when I boot to it it says device not found. Any suggestions PLEASE?

Is it a driver issue? You have to get the drivers loaded or you may be stuck. What steps have you taken so far.
I had this happen to me as well on another device but I loaded up drivers and then used adb to push files back over on a N4

Basically all you can do there is re-install the drivers, cause it seems they're non-existent or incorrect.
-reload the drivers [force them perhaps if on win 7]
-connect to pc with phone in fastboot
-in twrp go to advanced > sideload > start process
-add your rom to your adb folder
open a command window in your adb folder [shift + right click for short] then type adb sideload myfile.zip , and the phone will flash the file, and you can reboot.

Step 3: Run command and make note of code return
Code:

Now you should have 2 sets of numbers. first should be in the format of 0x0000XX where XX is numbers. And the other is 0xSSSSSSSS.
So now use the downloaded file and execute (obivously replacing the entries with what was returned above.
Code:
./cublock.py XX SSSSSSSS
This will tell you you have unlock.signed now. So move that to your fastboot/adb directory and then reboot to bootloader and issue this command
Code:
adb reboot-bootloader
fastboot -i 0x1949 flash unlock unlock.signed
Once done, get back to android and do the following:
Code:
adb shell
su
idme print
You should now see unlock_code: AAAAAAAA and on and on.
Now go flash my TWRP build in OG dev
Original credit goes to @dpeddi & @vortox for the exploit. I did nothing to this code and it is all their work. So give them thanks

This will tell you you have unlock.signed now. So move that to your fastboot/adb directory and then reboot to bootloader and issue this command
Code:
adb reboot-bootloader
fastboot -i 0x1949 flash unlock unlock.signed
Once done, get back to android and do the following:
Code:
adb shell
su
idme print
You should now see unlock_code: AAAAAAAA and on and on.
Now go flash my TWRP build in OG dev
Original credit goes to @dpeddi & @vortox for the exploit. I did nothing to this code and it is all their work. So give them thanks

Hi jmz,
I have a question here- all that was in your ZIP file was the cublock.py file.
Are we supposed to use this with the rest of draxie's tools in the HDX thread? If so, I was able to get an 'unlock.img' file, but nothing called 'unlock.signed'
maybe you didn't upload all the attachments we needed?
either way, thanks soooo much for your work !

sorry, with that tool you only get the unlock.img . I need to correct the post

In my linux box 'cuber' module, required by cublock.py, is not installed; is this the correct source? https://github.com/benesch/cuber
One more question: I forgot to block OTA update so my HD6 updated to 4.5.4, loosing root permissions. What I should do? Need to wait KingRoot supports the new software version or can I proceed to unlock bootloader and install twrp? Or could install, if available, a 4.5.3 recovery through dd? Very thanks.

I sense many roms being ported very soon...

Sure hope so!

I used the tools (cuber) in this post:
http://forum.xda-developers.com/kin...tools-create-unlock-img-fix-boot-img-t3050689

So i generated unlock.img, but i am still unable to enter fastboot mode,
i tried changing boot to 4002, i rooted and tried to execute fastboot file, nothing works tbh, how do you suppose i fix this?
thanks in advance

Need more info: Your computer OS, tablet device model (Settings>Device Options), Fire OS version (Device Options>System Updates). Tell exactly what happens when you run: adb reboot-bootloader.

These unlock instructions are for Fire HDs (4th gen). You need a fastboot cable for KFSOWI. Try G+ KFSOWI modding.

I am new to the tablet scene. This is my very first tablet. I would like to root the device and install custom recovery and hopefully custom Rom. Is this the first thing I do or should I start somewhere else?
