Did anyone tested this procedure??

YES, IT WORKS.
After this procedure, just update your Recovery (CWM or TWRP), using Flashify, available in PlayStore.
Thank you!

Did you use freegee to install cwm or twrp?

Hello, guitarboy21. Yes, I used FreeGee to install TWRP (version 2.6.3.6, something like that), ant then updated it to the TWRP 2.8.1.0 modded version using Flashify. And all worked out ok.
But first, before doing like explained here, I tried using LGOG Pro Recovery + TWRP using Flashify, and it softbricked my phone. So I unbricked it flashing the Stock 4.4 KitKat KDZ and did the procedure following the steps in this topic.
Gladly, now I think it's all good.
Thank you for your help!

Hey man! Congrats! Sorry it bricked your phone but its nice to hear that it worked. If you had flashed using freegee directly it wouldve bricked ur phone. Anyway, hows the experience? Is everything working good?
Do you have the option to disable capacitive keys and enable softkeys? I can help if ud like it.

Does this work on E98820b-MYS-XX with build number KOT49I.E98820b ?
When I reboot into recovery, it still shows:
Fastboot mode
udc_start()

This worked for me when nothing else would. Many thanks! I now have CWM Recovery where I had NOTHING before! :good: :good:

It isn't really an unlock. It is more of a boot certification bypass.

GASP!!

I can't believe I've found a custom recovery that actually...lol...backs up stuff. Other than the absence of Loki-fying Kitkat, this is not bad.:good:

This tutorial saved me a ton of headaches. Thanks so much.

It is work for me,too.Thanks.

got it working on 4.4, 20a ROM
thanks

Wow this actually worked when all other methods failed, thanks so much

Thank you so much!
This tutorial helped me to get out of the "Secure Booting Error! Cause: boot certification verify" error when try to boot recovery in a LG G Pro E989.

TWRP confirmed working

Today I had to backup my unlocked Razr M (XT905) using TWRP, wipe and then restore. I can confirm that it all worked.
I did have some issues with backing up to the external sdcard tho.

External SD really isn't well supported on the RAZR.. even in the os itself it doesn't really use it.
However that aside twrp works well on the Aussie hardware.

Thanks cellzealot.
Tried flashing it using "fastboot flash recovery twrp-recovery-scorpion_mini.img" in fastboot mode but still got stock recovery? My bootloader is unlocked.
Help? My phone's gone crazy and kept rebooting itself randomly.
Hmm...not sure what to say. That is the image I have on my dev XT907 and should work fine on XT905 with OEM unlock.
Have you tried the one originally posted here by P3Droid?
Either should work although the updated one has better support for JB.

Thanks cellzealot. It turned out, I forgot to get adb working on my computer but after I fixed that, TWRP flashed fine.

Tester needed

Anybody willing to try a flashable zip file on locked bootloader using flash gordon app? It's a stock kernel using andro-SYR method of flashing kernel via recovery but on locked bootloader I'm a little reluctant at the minute as this is my only device. I need someone with more confidence than me and not afraid to reflash stock firmware if it fails also I don't know if it would be possible to do it with the system running. Pm me if you want to try for me or any info you have that might be really helpful. I know your meant to have unlocked bootloader for custom kernels but testing is required

Bro I flashed it and during the flashing no system apps or nothing crashed and I was like its going to work and it said reboot required so I rebooted the phone but powered off but didn't power back on so I took the battery out and tried to power it on it just vibrates but doesn't power on.I guess its bricked or half-bricked. I'm flashing stock firmware again.
UPDATE:it's not bricked after flashing firmware again it turns on:good:
After testing the result is this doesn't work.
Thanks for trying mate just a shame it didn't boot maybe needs tweaking or something

UPDATE: Mate I tried to flash the boot.img via Flash tool & ADB but I get error's.

When I try to flash it via Flash tool:
I really doubt it will ever work with Flash Gordon.... It already bricked my device twice so I wouldn't rely on it to flash something like a kernel and the dev said it won't work for roms.

[Q] Bootloader, CWM & Rom help

I have managed to root my device after the 10P firmware! FYI, I used Android Kingo Root.
After looking into many posts, forums, etc... I have come to the conclusion that unlocking the bootloader is going to be trickier than any other device I have been successful with. I want to install CM 10.2 and CWM 6+, however, I cannot find solid information on how to unlock the bootloader for this unit. I would have liked to install the latest 4.4.2 from AT&T, but the device was rooted prior and AT&T will not honor the phone for the upgrade. At this point, I feel it would be easier to just install a custom ROM instead of trying to put the AT&T stock back into the unit.
Most of the info I see seems overly tricky and doubtful. I have downloaded FreeGee, but, in version 1.9.23 there isn't an option for unlock or disable security,(I have emailed the devs for the app). I also have gprorecovery.apk, but, I am deathly afraid to use it as I cannot find ANY material about it anywhere and I am worried to brick the one phone I absolutely love.
If someone has the knowledge, please share. Also, feel free to add in your experience and pitfalls with this device after manipulating the software. I am not 100% sold on CM, so if you want to suggest a great ROM...Feel free.
I appreciate the help and suggestions in advance.
No unlocked bootloader for the gpro. Sorry dude.

And then reboot to recovery as normal to install the ROM? I have read so much information that states you have to do some special presses of the buttons to get recovery to load. What are you running on yours?

Once you install recovery press power + volume up (asuming you powered down or resetted your device of course) until the lg logo appears ( some white letters will appear on the top left corner, release power button when they do). That will take you to the recovery. I'm. Using a cwm/twrp combo. I flash everything i need with cwm, twrp i keep since this phone has a tendency of going into a recovery bootloop and only twrp can get you out of it. Always keep your flashing files on the internal storage, sometimes flashing from sd card wont work.

Cant flash TWRP

Hey guys I'm kinda new to Android I've had a chappy phone and now an LG g pad after attempting root about a dozen times I finally managed to get it root now I am trying to get TWRP to backup the tablet and change the boot animation later but every time I tried on my pc it would fail so I installed flashify and tried with that I then I got a boot error saying security issues. The tablet stills boots but I believe the problem is the locked boot loader. Thanks for any help offered.

Have you installed root checker or another program to confirm that you do, in fact, have root? Start with that.
If you haven't installed a superuser app to handle permissions, I'd do that as well before trying to install TWRP.
I'll admit I had troubles installing TWRP as well, when looking at the forums, make sure you're downloading the version for your EXACT version of android and firmware, and following the instructions for the right version as well. Good luck!

[Need Help] ZE551ML Bootloop and No Fastboot

So, recently I tried to use this ROM: http://forum.xda-developers.com/zenfone2/development/stock-rom-ul-z00a-ww-2-20-40-168-t3354526
after revert back from CM13 custom ROM: http://forum.xda-developers.com/zen.../rom-cyanogenmod-13-0-nightly-builds-t3264492
But the result is my phone stuck in Asus logo.
Tried to access recovery by pressing power button + volume up but cannot go into recovery.
Tried to connect phone to PC via USB cable but the phone is not detected (cannot try fastboot from PC).
Here is what I did before my phone bricked:
1. Reboot into recovery (I'm using TWRP)
2. Wipe everything except MicroSD
3. Install SuperSU (downloaded from the thread)
4. Install ROM v168 (downloaded from the thread)
5. Reboot system
After that my phone stuck in Asus logo.
Tried to search solution from many sources still no luck. Already posted in the thread but still no answer from anyone.
Please help because I don't have backup phone :crying:
Thanks.
Did you really flash supersu before you flashed the Rom? That's probably the cause. Have you tried any of the bootloop solutions posted here yet?

If you cant go recovery try using this method..
It goddamn works ��
Requires sometime to understand it though. But you'll get it ��

I've followed the steps provided in the thread so I assumed that superSU was flashed already.
How to verify if it's flashed or not? Can I verify before moving on to the next step?
My phone is resurrected now thanks to steps provided by summit.
Could it be because I was using TWRP before?

1. Make sure your device shows up for awhile during boot
(when the phone vibrates upon boot)
2. Make sure you selected MOOREFIELDS.
3. Once done selecting the files " change the gp override flag under OPTION to 0x80000807"
