[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

[Q] need to update to stock image - i think?

Hello,
I bought a used galaxy nexus S that is on version 2.3.6.
It does not seem to be reading any sim cards and the baseband version is listed as unknown.
I think it may be on a custom rom because of this. I want to flash it back to a stock rom but have no idea where to start. I downloaded 4.1.1
the google site. which I can`t link to because I am new here..
my nexus s is I9020A so i downloaded that version of jellybean but have no idea where to go from here.
Are there any easy to follow guides? And am I even on the right track here?

I still don't understand what SNS stands for?
Google says social networking services... but step 8 is: Make sure the SNS is connected to the PC via the USB cable
So I doubt that..

here they are
read carefully the last image (i wrote some tips in the command window)

looks like SNS just means the phone somehow..

stop after installing google sdk, just plug your nexus in fastboot mode (turn off device, vol+ and power). then go to device manager (type in the search box, windows 7 or 8). and u will see android 1 (with exclmation mark). right click, update drivers, browse my pc, go to file nexussrootnew or got to sdk-extras-usb drivers, click "let me pick from a list...", chose all devices and install "adb android ...." dont know the right name. then u can go forward to the commands and install sotck images

-put your nexussrootnew folder in root of your driver (mine is: local disk(C: ) ) and in there put the images downloaded from here:
https://developers.google.com/android/nexus/images (be carefull to download the right image for your phone!!!!!!)
-unzip one time (in that unzip folder u should have a radio file, a bootloader file, a zip folder,and 2 more files that u dont need)
- put the unzip folder on: (C: ) / nexusstooneew
-open a command prompt (click "windows key+r" then type "cmd")
-check the pics and the commands
help understanding pics:
1: win+r and type cmd
2: "cd.." means go back in the previous folder and "cd" means open folder, hit enter to make the command work
now type:
-fastboot oem unlock (will erase all your data) to get your bootloader unlocked and the nexts steps working
- fastboot flash bootloader (drag and drop bootloader.img file)
-fastboot reboot-bootloader (wait 5 secs)
-fastboot flash radio (drag and drop radio.img)
-fastboot reboot-bootloader
-fastboot -w update (drag and drop the zip file wich is in the main folder of the android image that u downloaded) (see 4 pic, the file is hightlighted) ("-w" means full wipe = clean install)

Blackstone - Fastboot Problem

Well I am trying to Flash the latest fagyi NAND for Blackstone - http://forum.xda-developers.com/showthread.php?t=1914723
So I did everything, but when I reached the fastboot thingy, I did this:
After ROM flashed, took batter out and restarted device.
Blue screen showed up, forced fastboot, ready USB state, so I connected to PC
Then I opened a command prompt, so now what should I enter in the command prompt! I am using fagyi's fastboot!
Thanks, in advance!

Sorry for double posting, but please someone answer me, or atleast give me a tip/advice!

Do you mean this part?
13. Now connect the Blackstone to your Windows OS and open a CLi/Command prompt
14. Within CLi go to the directory where you place the 'adb files & fastboot.exe' files (from step 2)
15. Type: fastboot flash recovery recovery.img (this will flash install the custom CWR)
16. Then type: fastboot boot recovery.img (this will reboot your Blackstone into CWR)

Yeah that exactly!

Step 2 says
2. Extract the 'adb files & fastboot.exe' files to a folder
Click to expand...
Click to collapse
so the 1st question is, do you know what folder you put those files in? Note that we're talking about your computer, not your phone. On your computer, open a command prompt by doing Start -> Run... -> cmd (This is Step 13). Navigate to the folder from Step 2 This is Step 14). Then, type the appropriate commands from Steps 15 & 16.
Still don't get it? Ask away!

Um the files are placed in C:
And when I enter the commands, it says 'File too big to fit in memory"? What do I do now?

So your step 14 should be to type cd c:\, then 15 fastboot flash recovery recovery.img
Is that when you get the error?

Yes, exactly then!

Ok, try redownloading the fastboot program, or install the Android SDK to get the newest version directly from Google.

I've redowloaded it alot of times! And I already have the Android SDK and am using the latest one!

Are you sure that you're using the correct version of all relevant programs? By that, I mean 32 vs 64-bit.

I am not sure about that, how should I know?

Do you get the same error if you type fastboot devices ?

I havent typed that yet!
EDIT: No I get this - "RH104393397 fastboot"

LG Aristo 2 ROOT (LM-X210[Build- X210MA10i])

===============================================================================
TUTORIAL REVISED AND WRITTEN BY @parcek
===============================================================================
FURTHER UPDATED FOR ROOTING NOOBS: 10 Steps
Two Methods: Windows and Linux
Originally posted by @brad2192: https://forum.xda-developers.com/android/development/lg-aristo-2-root-t3746425
Credit to @tecknight for updated files: https://forum.xda-developers.com/showpost.php?p=76837384&postcount=2
@brad2192: Updated Tutorial due to people using TWRP (the original tutorial was released before TWRP was released for this device)
1) Backup all apps and data using LG Backup phone apps
2) Enable USB debugging and Unlock OEM. There are two methods in which you will to accomplish this:
First Method: Smartphone GUI
A) On your Lg Aristo 2 Smartphone go into General Tab (If in Tab View), If in list view, scroll down towards System section
"System Settings > About Phone > Software Information > Click on "Build Number" 10 times.
Now go to "System Settings > About Phone > Developer Options > Enable OEM unlock."
and also "System Settings > About Phone > Developer Options > Enable USB debugging."
Second Method: Windows Command Prompt or Linux Terminal:
Windows:
B) Click and drag "adb" file into command prompt and type "reboot bootloader" after it. Press enter.
Click and drag "fastboot" file into command prompt and type "flashing unlock" after it. Press enter.
Linux:
C)Type in your terminal "adb reboot bootloader" and press enter.
Type in your terminal "fastboot flashing unlock."
NOTE: Below has the information which will teach you how to download ADB and FASTBOOT.
3) Download the following:
Updated - TWRP
Updated - Magisk
(Add this file into your phone's SD Card.)
Updated - boot image
Update: Windows:
B)This is how you download ADB and FASTBOOT for Windows: https://dl.google.com/android/repository/platform-tools-latest-windows.zip
4) Open Command Prompt. Then click and drag the adb file (from the latter download link a.k.a platform-tools) into command prompt then press space and type "reboot bootloader" after and then press enter OR power down phone and hold volume down while plugging in USB)
5) Open Command Prompt. Then click and drag the fastboot file (from the latter download link a.k.a platform-tools) into command prompt and then type "flash recovery" after it and then click and drag "newtwrp.img" into command prompt and press enter.)
6) Open Command Prompt. Then click and drag fastboot (from the latter download link a.k.a platform-tools) into command prompt and then type "flash boot" after it and then click and drag "bootimglistedabove.img" into the command prompt after and then press enter) then follow step 7).
Update: Linux:
C) Depending on kernel, for this sake we will use a debian based kernal.
This is how you download ADB and FASTBOOT for Linux: Open terminal and type: "Sudo apt-get install adb && sudo apt-get install fastboot"
4) Open terminal and type: adb reboot bootloader
5) Open terminal and type: fastboot flash recovery (and then click and drag newtwrp.img onto the terminal) and hit enter
6) Open terminal and type: fastboot flash boot (and then click and drag bootfilelistedabove.img onto the terminal) and hit enter
This applies towards both Windows and Linux: continuation after their last listed step written above.
Step 7) Remove battery from phone, in order to force a shut down.
8) Boot into Recovery-TWRP Mode.
How to boot into LG Aristo 2 TWRP Recovery:
a) The phone is off.
b) Hold the volume key and power key at the same time.
c) When the LG logo appears, let go of the power key (while still holding the volume down key) and then click and hold the power key once again.
d)You will be prompted to LG Aristo 2's stock recovery mode asking you if you are sure you would like to delete ur phone.
e) Go to the option "yes" and enter.
f) It will then warn you that can remove all data from your phone.
g) Go to the option "yes" and enter.
You will be in TWRP after this.
TWRP Mode:
9) In TWRP go to "Wipe > Format Data" and then type "yes" and confirm it. (Do not hit reboot, click back a few time and hit reboot > recovery)
10) In TWRP go to "Install > Select Storage" and select your SD Card. Then look for where you placed the "magisk" zip file. Install it.
Your phone is now rooted.
On TWRP menu: Reboot.

What root means: In terms of PC language, Root means the superuser that has privileges to Add, Modify, and or Delete any kind of system files without prevention. Pretty much, it's like the actual Administrator account on a PC. Natively, whenever we buy a phone, it is as if to say, we are only using a guest account. Since the android OS is basically a Linux based computer (correct me if i am wrong) we can do anything we like... You want iOS emoji's on an android? A custom boot animation? Having root privileges allows you to go beyond your guest user restrictions because you then become the Admin.
Explaining the function of the provided Magisk app: It allows root privileges for programs intended for rooted phones.
There are other popular programs alternative of Magisk app, such as the SuperSU app: http://www.mediafire.com/file/2dljobq6yw93w76/UPDATE-SuperSU-v2.82-20170528234214.zip
--------------------------------
After being officially done setting up your rooted phone, make sure you disable OEM Unlock to avoid seeing the caution message before every boot.
--------------------------
How to backup your phone.
Also, using ADB, backup your phone.
Windows: Click and drag ADB file onto command prompt and paste " backup -apk -shared -all -f "C:\Users\UserName\Desktop\backupfilename.ab" "
Linux: Open terminal and type " adb backup -apk -shared -all -f "C:\Users\UserName\Desktop\backupfilename.ab" "
Update: For those who are encountering "Now unlock your phone and confirm operation" when typing the latter code, there is an alternative and much more easier and safer way to backup your phone.
Boot into TWRP and click on "backup" and then select what you would like to back up and then swipe to confirm the operation.

Brad I have a question, is there any way to get a custom ROM on this phone? If not how come? How does it all work?
And are you with Metro PCS as well? What apps can a safely delete to get this phone as close to a stock version of android as I can? Can I seriously just wipe out EVERY metro app? Hows your phone functioning?

Until there is a custom recovery built, we won't have custom roms. Dont wipe out every metro app. Anything you arent sure about, look up, or just freeze the app and test results. My phone is fine except SuperSU wont work properly due to the binary being occupied, but this is the best we have so far. I debloated no problem.

Root is the only thing needed, not a custom recovery. Apps like Magisk Manager can flash custom images. The reason there is no ROMs built for this device, I can tell you in my opinion there is no need for a Custom ROM. Magisk Manager has plenty of customizations available as well as many other root apps. Basically, custom recoveries are obsolete, it is not needed for gaining root access nor flashing files. Magisk can do it as well as Flashfire.

Hey man, I would press the Windows Key+R and type" "cmd"
Then, as long as your adb is located at C:\adb type: "cd C:\adb"
Then use adb, I hate how Windows 10 forces it on users!

Hey, I am so sorry to bother you but when I enter in the fourth step of your tutorial, it tells me "flash boot" command doesn't exist. Is there something I'm doing wrong?

Okay, after messing around with it a few, I found that once it goes off into fastboot... my computer can't recognize it anymore?

Hey guys, spent a few hours figuring out how to root. Pretty Simple!
1) Enable Developer Options, USB Debugging & OEM Unlock
2) Reboot to Fastboot Mode (Using ADB via PC type: adb reboot bootloader)
3) Add root_boot.img into your adb folder
4) In ADB type: fastboot flash boot root_boot.img
5) After flash successful, type: fastboot reboot
6) Install Magisk Manager App
For those skeptical, proof of root here.

Do I need to unlock the bootloader first? I have it rebooted into fastboot and it's giving me instructions to do that, but won't let me push the boot image. If I do need to unlock it, does it wipe my device?

Yes, that is what OEM unlock means. In doing so you do need to unlock the bootloader.

Just wanted to make sure but does it wipe it?

Yes, when you use "fastboot oem unlock" it unfortunately erases all data. One of our forum members is working on a TWRP at the moment that might be available today. You could wait to do this so you can create a backup.

That'd be cool. But, wouldn't the bootloader still need to be unlocked for me to flash TWRP?

I'm an idiot, yes LOL. Sorry, just got to work and I am tired you are correct. So, if you would like I suggest just using my tutorial. I believe there is ways of using LG backup to save most of your user data.

I posted a test twrp on my blog for aristo 2

What are you typing into ADB to get that error?

Do you have to de-encrypt the phone for root? I am thinking of getting an Aristo2, currently using the MotoE4 (which I hate!), and rooting that requires de-encryption (I love encryption!). This is the MetroPCS version your talking about? Thank you...
