fastboot mode and recovery mode not working

ok so my gf was on stock 2.1 .
and i wanted to put cust ROM on the phone .. i could not get into fastboot or recovery and found that i need 2.1 with fastboot kdz . so i downloaded that installed via kdz updater . and could still not get into it. so after some searching i found a clockwork rom kdz and downloaded installed that and still cant get into fastboot or recovery ..
here is what my phone is saying in about phone after clockwork kdz flash
gt540
2.1-update1
2.2.29 [email protected] #1 tue oct 5 15:18 edt 2010
gt540-v20a-oct-05-2010
i personally dont think either of the kdz's i flashed worked
also she is rooted
can anyone give me a hand please so i can put cust ROM on her phone

Ok first i need to know what KDZ with fastboot you flashed, second did you check that the KDZ show -- FINISHED -- after 5-10 minutes that takes the process to finish?
What are the combo buttons you're pressing for get in fastboot?
The proper way is CAMERA+POWER BUTTON ( Hold camera button for 1 sec then hold power button without put down camera button, so both buttons needs to be pressed)
The phone will boot , you'll see LG LOGO then after that you should see a dark-blue clean screen (no logo, no letters, NOTHING! just a clean screen). If you get in the mode, congratulations, you are in fastboot now!

Hi IM not on PC at the moment. But I downloaded the 2.1 with fastboot from Modaco (I think) and on the kdz it said all things like param 1-128 call ended and a few other things but noting said fail and then it said finish. I did leave it for about 5 mins after it said finish before I exited and unplugged. I also done camera power and it just boots phone normally.

ok now that you there try with the KDZ modified by Mur4ik so you get data2system method too...
so follow this:
http://forum.xda-developers.com/showpost.php?p=13620585&postcount=1
Advantages: Its the lates stock 2.1 ROM released in March 2011, it has fastboot and support for recovery as well plus it has been modified for get 238MB of space for install apps.
PS: *When it get stuck at --apram 244 - 245 you done is normal (you wont see -- FINISHED --)
* the process will take 5 minutes, not even 10
* the fastboot screen is blue, more like electric blue with white letters wich is very different than the normal fastboot mode we are used to, so dont panic is normal.

Is the screen blue with white letters?, if so then you are in fastboot.
What O/S do you have xp, windows 7, 32, 64 bits? you need to install the proper drivers for your pc recognize your phone in fastboot mode
Download Drivers for your computer recognize the phone in fastboot mode. Unzip and put the files inside the folder in C:\android-sdk (take a look of the 3th image)

Look for a file v10d_downgrade.kdz in the net, you have to flash that. And the flash whatever kdz you want
It wont work with other kdz.

It does not work, the KDZ throws me the same error. Look:

DELETED sorry wrong post

First of all reinstall the drivers on your computer
Then, did you try to remove the battery, plug the phone to your computer (without the battery), then try to start the phone in Emergency Mode?
If you get to the Emergency Mode with the correct drivers installed, you should be able to flash anything from KDZ.
This method was the only way I could get my L7 in Emergency Mode AND recognized by KDZ, so you could be in the same situation as me maybe?

That method never worked for me, did you get a "UpTestEX_mod2_marwin.exe" in the packge that you downloaded? Use that, select emergency and the v10d_downgrade and flash! (follow a tutorial, you need to install small http server before...... like here)

have u tried "vol down" + "power button"
and when buttons light up, press the "menu" button
and do it a couple of times?

Nothing I've read has worked for me, trying to read the information on the device I get this:

Let pass without touching the screens and it appeared this, the touch screen does not work at this point, I touch it and nothing happens.
At a time when one of the combinations I appeared the cwm recovery, but when I restart the screen turned white and yellow of the previous photos.

Hey friend. I have already almost lost my phone several Times.
But persistance is the best to resolve your problem.
Firstly ur phone isnt bricked as it turns on!!!
So try this:
1° turn off phone
2° bottom up + down + turn on
3° should apper "emergency mode" [if this didnt work, try And get in this screen"
4°flash KDZ ( MAKE SURE ITS ON EMERGENCY MODE ON KDZ UPDATER ! AND THE MOST
IMPORTANT WHEN YOU FLASH IT WILL POP UP SEVERAL ERROS . DONT DO NOTHING LET IT CONTINUE )
5° Phone will boot loop (resolve it making a HARD RESET (bottom down+ menu+turn on)
6° now it will reset everything. Then u must flash AGAIN KDZ UPDATER (BUT NOW IT WONT SHOW ERROS ON KDZ UPDATER )
Job done
Phone recovered
PM ME IF ANY DOUBT OCCOURS
Sent From ... Lg e400 <-- {[Brasilian Here]}

Enter in DIAG MODE vol up+vol down+ turn on
(Just do it IF -> u have tried my tip ABOVE this one.)
After that , make sure u connect ur phone then, flash in KDZ UPDATE.
NO ERROR . THIS MUST WORK FOR YOU . AND AS I SAID
IF IT DONT RECONIZE YOUR PHONE THEN U MUST HARD RESET IT .
Sent From ... Lg e400 <-- {[Brasilian Here]}

Finally I could fix the problem without using KDZ and now I want to share with the community.
1. Remove the phone battery.
2. Press the button '+', and connect the usb (without battery).
3. Wait until the drivers are installed on the computer.
4. With the program of LG Mobile Support Tool, and with the phone connected press "Upgrade Error recovery" within the program.
5. Let it download the rom, you unzip and install.
Note: All this process without the battery attached to the phone.
That's all

Bootloop on CMWR and phone never close, only without battery!
Hello.
Today i want to upgrade my android, and surprise! When i push "install"and phone is was restarted, is entered in a continuos loop restart directly in CMWR mode. Here, it was impossible to install anything or make any changes, only "restart", and again, the phone is restarting directly in CMWR mode. At first I thought I bricked my phone, because even in emergency mode it could not start
BUT all this is madeit with battery inside!
After reading what was written here, I realized that I have to remove the battery, and surprise, on the second attempt i managed to start in emergency mode! (with usb cable connected to PC! ) :laugh:
Good...
Now, i openet the "LG Mobile Support Tool" (with usb connected to PC), and after LG mobile tool i let to check and install the last version of USB drivers , it was able to communicate with my PC. After that, i installed the latest available version of Android, via LG Mobile Tool and now is working.
BUT i lost the root of the phone. Anyway, it's the phone of my wife, and she's not interested in "walked" through it
Thanks to "andersonlima" , i understand that as long as boots, is not bricked !
Good luck in the future, and most importantly, read well, with calmness, that can occur various ideas, along with what you have in face, may lead to solving your problem! :good:

LG G2 D802 stuck on gray lines

I got a new LG G2 D802 today, managed to root and I used AutoRec to install TWRP. The app said it was successful but as soon as I booted into recovery, I get this screen and it's stuck.

Really, really appreciate anyone that can help get me back to a working phone - I'm using a mac.

So when you turn it on your phone after turning off you don't see the LG screen but only the lines? or only in the recovery?

Try entering download mode - poweroff the device -> hold volume up and connect to pc. Then try flashing your stock firmware.

Just tried that - it switched the phone on - the lines moved around again then settled into the screenshot.
Do I need the drivers installed on a PC for this to work? I tried it on a mac with Android File Transfer.

You need windows + lg flash tool 2014 + your kdz, drivers would install through the lg suite.

Unfortunately I can't get to the dialer to get my IMEI. I know they used to be under the battery but thats obviously a no no on the g2.
Regardless, I found the .kdz here http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/Hong+Kong+D802/
Installed the drivers, LG Flash Tool 2014, attempted to put my phone into Download mode (The phone has the grey lines in different places) but the PC still doesn't recognize the phoen when I plug it in and the flash tool cannot read the phone also.
Any other suggestions please? Thanks.

You may also try the tot method.
Can you recognize if the image behind the lines is small (centered on the screen) or a larger one ?
Because it might be that you've got blue circles, which are shown prior to entering the actual download mode..

I don't actually know if its going into download mode or not. I've taken another photo as below which shows what my phone looks like when plugged in, the lines move around like an animation to start of with then settle in this position - there isn't actually anything behind the lines. It's almost as if the screen is messed up and the pictures aren't displaying correctly. I seriously doubt it is a hardware issue as it was working just fine before using AutoRec.
Just so annoyed at myself for doing this so soon after I got it -_-

1. power off
2. hold volume up and connect to pc
3. flash kdz

Did you install the drivers or not ?
I'll send you few links later, please remind me one more time via inbox.

Iam facing the exact same issue right now
Phone was already soft bricked. user to get stuck at the lg logo and download modestopped working , volume + power would bring fast boot so i used adb command prompt and flashed boot,aboot and recovery files and then did a reboot and all i have are these moving gray lines
IF anybody resolved this issue please help with the steps

I have a same problem. Please help me, please !

Where did you buy the phone? Some online sellers combine parts from all variants and sell refurbished phones under D802 so when you flash it bricks your phone.
Do you have IMEI on box?

Same thing happened with mine. Got it fixed for 20$ through Jtech service.
Beware people.

But flash tools fail to connect device. please help me to solve this. I am a Sri Lanka. If you a place to repair my phone. Please advise.
Thank You.

Same thing happened with me when i use autorec, lines on the screen but the phone work normally, receive calls and messages, the touch works normally, every thing work normal but there's no screen output or colors only gray lines wuth black screen. I think it's a refurbished phone with a different board that written on the cover, and we use the wrong autorec according to the board.
I don't know how to fix it. Any help ?

Errors while trying to update LG-E612

So I got this phone off a friend and I factory reset it which all worked fine, then I thought I would update it before I got to far. I have not had any success, I have even scoured the forums and the internet without any success so I'm hoping that someone with some experience may be able to assist or point out something I am missing. The phone is stuck in Download mode - I can't get it to boot to the rom at all.
I have a feeling there may be corruption on the phone - You'll see why a little further down, however I cannot be sure.

I have tried every method to get the update to work that I can find.
I started off by installing all the LG apps and Drivers. The phone is recognised from what I can tell.
I downloaded a couple of stock roms
When I open LG Mobile Support Tool - It says the software is up to date. When I go to 'Options' the only option I get is 'Update Recovery' which I chose and let it download and start installing. Once it gets to 4% is stops. I have pulled the battery and tried over and over again but it keeps stopping the update at 4%. I have even tried removing the battery completely and continuing the install but the same thing happens.
So I tried this over and over with no success. I tried with battery, without battery, I tried getting in Emergency Mode with no success. I tried booting into the OS with no success. So I continued surfing looking for answers.
I found KDZ and thought this might be the missing piece of the puzzle, however this kept crashing every time I tried loading info from the phone and even when I skipped that and just tried installing the ROM.
And the data in the log file looks out of place...
I played around with this hoping to get it to work, but I couldn't. I tried CDMA and it kept failing and it wouldn't even attempt to install the ROM.
So the next one I gave a shot was LG Flash Tool 2014.
This is the only info I can get to pull from the phone.
I am out of options and I'd really like to get this sorted without having to send it off for repair. I see there is an IMEI error - Does anyone know a way for me to repair it?
Any suggestions or experiences you can share that may help would be really great.

I haven't viewed the images, but try this
-Goto download mode.
-Open KDZ updater
-Select the kdz, select 3QCT (something like that) and DIAG (forgot the options, its been long since I flashed a stock ROM)
-Flash the kdz
-KDZ updater will crash, it is quite normal
-Do a hard reset (remove battery, put it back, vol - + power + home, when it vibrates remove power and hold on vol - and home for another 5 sec)
-Hopefully, it should boot..

Bootloop Android 10: enablefilecrypto_failed boot issue after recent update

I got an OTA security update few days back. The update was done successfully. Then I ran out of charge and the phone switched off during usage. When I charged and tried turning back it on, the phone got stuck in the android one screen and it rebooted. It again got stuck in the android one screen and the following message opens up in android recovery mode.
Code:
Android Recovery
Nokia/Dragon_00WW/DRG_sprout
10/QKQ1.190828.002/00ww_4_10D

Use volume up/down and power.
Code:
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.
Then it shows options to select either Try again or do Factory data reset
The following code is shown at the bottom
Code:
Supported API: 3
Boot Reason: enablefilecrypto_failed
I found a similar issue in Nokia 7.1 after January update. The phone does not boot up. Is there a way to solve this issue?
I have some important data in my phone. Is there a way to recover them before resetting the phone?
Note: The phone is in stock condition with only usb debugging on.

Change slot, boot the device make sure there's enough storage available and then apply update.

same probelm , it return to recovery mode , any help

On these phones. If phone stuck on Android One screen.
And when doing factory reset from recovery, if device stuck at wiping data.
Then it is a dead EMMC.

Same problem, can anyone help?

today i tried to flash OSt service tool this type problem facing device... than find [15:15:42::203][03964] [FB]: [Recv] FAILError flashing partition : Write Protected this error.... thats mean motherboard damage.

Tried it and no improvement. Could you explain in detail so that I'll check whether proceeded correctly or will try again.
Is there any way in which I can recover the data even before the problem being solved?

At this point there's no way to recover your data, and the guide to change the current active slot you can find in the below link
https://www.google.com/amp/s/www.te...-stuck-on-download-mode-after-ota-update/amp/
The issue mentioned might not be similar but the solution you're looking for could be it I had a similar problem with a 7.1 that can't boot after a security patch update and everytime the update will download and after restart the phone will throw error and ask to factory reset I couldn't test this method on that phone as the person had set it up for work after a reset and willing to hold till he can visit a service center. And he said he didn't have much storage at the time of update so it got corrupted somehow

I tried the method I mentioned by changing the slot, my current slot is b and update is supposed to install on a, a is corrupt or something as soon I changed active to a the device will bootloop in android one screen and go to failed page and ask for reset after which it will boot on slot b, also tried to install the Feb SP manually which installed fine via adb but again after reboot it will act same, so the only way is to visit a service center or better pay it directly for a bootloader Unlock service to avoid any future software problems

Same issue I was facing but is fixed
So what did I do?
Downloaded stock ROM and installed using OST LA.
Then the update was installing but failed. [I was trying from last 1-2 months but getting same enablefilecryto_failed message but finally I solved it]
I downloaded OTA from website of same update and installed via ADB.
After installin OTA, It said it needs to "Format data" upon reboot.
I formated and mobile now has "Stock ROM".
