[Q] L3 can't boot on recovery

Aim: Flash CM9 ROM
Friend's L3 E400, bricked his phone and somehow managed to unbrick it and root it. No idea what kind of ROM he had on. It was GB though.
Got it on my hands today, tried to get into recovery by pressing Vol- + Home + Power. Phone got wiped (not exactly factory, but reset) and was asking for Google info as in starting it up for the first time.
So no access to recovery.
Rebooted to bootloader and flashed CWM recovery. Same thing happened, phone reset itself.
Downloaded the LG KDZ flasher, and the Greek Cosmote KDZ file and flashed it.
Tried to boot into recovery, still no luck.
Phone is no longer rooted. Tried to root using the usual script and i'm getting permission errors.
"adb reboot bootloader" : is working fine
"adb reboot recovery" : resetting phone
"adb reboot fastboot" : same as "adb reboot recovery"
If anyone has any tip for me I would be really greatful!
Tried a lot of things without any luck.
Tomorrow I'll have a discussion with my friend and elaborate a bit more on the issue.

1. Reinstal system
- Download latest system for you from http://lg-phone-firmware.com/index.php?id_mod=11
- Install normal by KDZ
2. Root phone
- Download attachment (maybe you should deactive antivirus for 10 minutes)
- Connect phone with USB Debbuging
- Open SuperOneClick
- Check "rageagainsthecage" in progam right side
- Click root
- After installation click "Yes" (root test), "OK" (su promp confirmation), and "Yes" or "Not" (donation)
- You have root
3. Install CWM
- Do that: http://forum.xda-developers.com/showthread.php?t=2405279
- To open CWM boot phone: Vol Up + Home + Power if not work use Link2SD or other app to "run in recovery mode".
4. Press "thanks" and dance for me!
- Regards!

On my LG L3 e400, it's volume down + home + power. And when the phone vibrate, I release the power button. I wait to be in recovery mode to release the others

You should have over 1 MILION likes of that post! Thanks mate, that's works!
I wanna dance for you: *shaking ass*

We managed to root the phone with your way!
We are now at the point where we "install/update" the CWM from ROM manager...

Why does it show that i have 2 recoveries installed?
Clicking any of those 3 buttons gives me an error, that it couldn't connect to the cwm's server...
Being more descriptive:
1. Installed the KDZ.
2. Rooted the phone using SuperOneClick.
3. Installed Terminal Emulator and ROM Manager.
4. Tried to use the ROM Manager and got the "can't connect error"
5. Tried VolDown+Home+Power to boot into Recovery. Phone opens up but factory reset. (Terminal Emulator and ROM Manager not installed anymore, but phone is still rooted)
6. Tried the Terminal Emulator to installed the recovery and at "# dd if=/sdcard/cwmrecovery.img of=/dev/block/mmcblk0p17" i get "Cannot open for read. No such file or directory"
7. Tried to boot into bootloader and fastboot install the recovery zip into the recovery partition.. Seems to have worked fine but when booting into recovery phone factory resets again.
PROBLEM SOLVED BY REPEATING STEP 7!
Managed to get in the recovery after all, and therefore installed the CM9. All good! THANK YOU ALL

Xiaomi Redmi 2 2014811 bricked after updating SuperSu binary in recovery?

I'm not rly good with electronics etc, my phone came with root access permissions via Security MIUI app so I installed SuperSu to manage it easier (MIUI app reqiured to manually check each app to allow access), no custom ROM or anything installed, the way it happened was
1. updated supersu from google play
2. entered supersu app,it asked me to update su binary
3. I clicked yes through recovery
4. it rebooted and got bootlooped.
It's stuck at the "mi.com" screen when turning on, can't go into recovery, fastboot mode only shows an image of Miui mascot without any fastboot options. I've followed some tutorials online and got the thing below from minimal adb.

Fastboot will show that android icon only.
No fastboot options will be available there.
Now you need to perform some steps to recover your device..
Note - Your data will be wiped. Also, remove memory card (if any).
Now let's start the process -:
Download MIUI Fastboot ROM file.
Here's the link..
1GB RAM model - http://update.miui.com/updates/v1/fullromdownload.php?d=wt88047_global&b=F&r=global&n=
2GB RAM model - http://update.miui.com/updates/v1/fullromdownload.php?d=wt88047_pro_global&b=F&r=global&n=
Also extract this file and put in C Drive.
Now turn your PC on..
And install latest Mi flash tool. http://api.bbs.miui.com/url/MiFlash
Turn your device off. By pulling battery. (Assuming that your device is in bootloop).
Go to fastboot mode (power + volume down)
Now turn your PC on.
Open Mi flash tool.
Connect your device.
Click on refresh button in flash tool.
Now, it will show some random numbers. (This is your device).
Now, select your ROM fastboot file which you downloaded and extracted.
After that, choose 'flash all' and click Flash..
It will take some time.
After that your device will be rebooted.
Voila! Your device is back to life!

I have problem with recovery. Help please !

Hi. First i want to say is sorry for my bad english.
I unlocked the bootloader of my g6 and i have flashed Twrp recovery, but when i try to go to recovery mode i have this messege : " your device cannot be checked for corruption . please lock the bootloader ".
Can anyone tell me how to resolve this because i want to flash custom roms but i cant because i cant go to recovery mode..
Help me please.
Sorry if there was a topic like this, but i can not find a solution to this problem.
Now i see when i go to ADB folder and write the command " adb reboot recovery " after the reboot it says " No Command " and i cant do nothing .. I cant flash.

If you mean this screen ^ that is a normal screen that appears, with every power up / restart, after the bootloader has been unlocked.
I think of it as a "red badge of courage".
As to the question about adb commands, what is it that you are trying to accomplish?

Some more information is needed to help you.
What is your model (h870, us997)?
Are you sure you properly installed twrp (reboot to bootloader, fastboot flash recovery twrp.img)?
Which version of twrp did you use (official, Melina, eliminater's (recommended))?
Regarding your adb problem - do you fail to reboot to recovery using adb from within? Have you tried to turn it off and on again?? I mean, turn it off and try the button combination to enter recovery (turn on holding vol- and power, when logo appears, release power and quickly press again and keep holding both until "factory reset", confirm twice).
Information is key!
PS as the previous poster wrote - if you unlock your bootloader you get the warning screen, just ignore it.

the "your device cannot be checked for corruption" screen is normal, it happens when you unlock the bootloader, no issue there, in order to install TWRP you must:
1. plug your phone in and type 'adb reboot-bootloader' to boot into fastboot mode
2. flash the twrp image via 'fastboot flash recovery TWRPIMAGENAME.img'
3. This is important!: type 'fastboot reboot' and hold the rear button and volume down during the shutdown!, when the LG logo shows up quickly release JUST the rear button and press/hold it again, you should see a factory reset prompt screen, press yes both times, and you should be dumped into TWRP, at this point you can reboot from within TWRP and you should be fine.
Explanation:
the stock LG rom with overwrite the recovery if it determines it has been changed, by booting to TWRP before booting the ROM, TWRP will modify the ROM to stop it from overwriting the recovery allowing TWRP to stay after booting.
I hope this helps

THANK YOU SO MUCH .. It works .. The problem was in the buttons.

I have another problem.. When i try to go to recovery..the only what i see is the logo of TWRP and then the phone just reboot and i cant do nothing.. The phone is h870. What i have to do to have normal TWRP because i want to root it..

Try another twrp version. For Oreo afaik only Melina and Eliminater (which is a continuation of Melina) work. I recommend Eliminater's version, it's up to date (v3.2.3) and backup works - at least for me. I'm on H870 Oreo 20b.
For Nougat I have no experience, as I got my phone recently and never downgraded. But as I understand it from others' experiences, for full custom ROM functionality (e.g. fingerprint) Nougat bootloader is preferable. Search the forum, the information is there!

Yes, I use Melina TWRP, flash Version rel_o2 (or latest) using the method I said above.

Where i can find those versions of Twrp ( melina, eliminater ) ?

[Solved] H990DS only able to boot into fastboot and static screen

Hi,
I was trying to install Super Rom but unfortunately I am unable to boot the phone. I had rooted the phone a while back. When I try to turn the phone on I get stuck with the dreaded static screen which is normally an easy fix however I can't boot into TWRP as that gives my a static screen too. The only thing I have access to is the fastboot menu and when I try "fastboot reboot" I get stuck at the LG "lifes good" screen. I have tried to flash two different versions of TWRP (one given in dirty santa and the most up to date for H990DS).
Any ideas will be greatly appreciated!

Don't use fastboot reboot. That starts it booting the stock rom, which before the first boot into twrp reflashes the stock recovery again. You need to pull the battery to leave fastboot, then boot into recovery by holding volume down, holding power until the screen turns on, then tapping power repeatedly until it asks to factory reset, say yes. When twrp boots swipe to allow writing to system and flash something. Then booting the rom won't eat twrp anymore.

So I can now boot into SuperRom but I am unable to go back into TWRP. When I do the usual button procedure to get to TWRP I am asked to do the LG reset thing, I press yes twice and then I am met with this screen:

To boot into Android I need to open fastboot and reflash the recovery, then reboot but I still don't have any access to the recovery. Any ideas?

I'm fairly certain that's the one I'm using, but ill re-download it and try again.
Just downloaded your version and it was indeed the one I have been using already. I did however download it again and tried to reflash it using the method you stated above but I end up with the same screen. The only way I can get it to boot into Android after that screen is to boot into fastboot, flash your recovery then "fastboot reboot".

Problem solved! Solution:
1. Download the TWRP app from the play store
2. Using the app, flash Phoenix591's TWRP (here)
3. Use ADB and reboot into recovery using "adb reboot recovery"
Once I did these steps I was able to use the usual method (volume down, release power for one second etc) to boot into TWRP. Happy days!

Mi A1 Bootloop after ota update and Locked Bootloader

Hi,
I've installed an ota update and the device didn't boot... it is stuck in a bootloop....
When i try to flash via fastboot, it appears an error saying that the device is locked ant cennot erase...
via fastboot oem unlock i get the error message: Remote: oem unlock is not allowed
via MiUnlocker the unlock gets to de 50% and gives an error and on its logs it says: Remote: oem unlock is not allowed
I tryed to flash TWRP with command fastboot flash recovery but the error is the same: remote: partition flashing is not allowed
Can anyone help me please??
I'm stuck on the bootloop i can't go to setting - developer - allow oem unlock option!!

Have you tried doing a Factory Reset from stock recovery?

This is a strange behavior, even if an OTA update corrupted the system for some reason, the phone should boot from the original slot.
Have you tried switching slots manually from fastboot ?

How can i do that?

Hello!
I've faced the exact same problem yesterday.
You need to force the phone to boot in EDL mode by opening the back cover and short circuit 2 pins as shown in THIS video.
After you have the phone in EDL and being detected by your PC (you need the correct drivers, you may get them on THIS thread by @CosmicDan), you may use MiFlash Tool to flash official PIE Rom, access developer options and enable oem unlock to be able to unlock your phone again.
If you wish to revert to Oreo, please use THIS guide.
Cheers!

Actually you have a recovery. You need to long press the power button and, afterwards (not at the same time), press the volume + button. You'll see that all options will appear.
