Bootlooped/bricked/returning to stock ...see the method here

You may be have got attracted to those new roms out there on the internet and would have probably bricked your device.Or maybe did some modding and in worst case somehow your phone bootlooped.
so please follow the guide for unbricking or solving bootloop issues:
CAUTION:
[1] FIRST OF ALL, I AM NOT RESPONSIBLE FOR ANY DAMAGE TO YOUR DEVICE.
[2] NEVER UNPLUG THE USB CABLE WHILE FLASHING IS IN PROGRESS.IT MIGHT PERMANENTLY BRICK UR DEVICE..
ONLY FOR ZENFONE 5,A501CG/00CG
download the required files:
[1] kitkat firmware: for zenfone5(a501cg/00cg only other zf5 users download appropriate firmware from asus support page): http://dlcdnet.asus.com/pub/ASUS/ZenFone/A500CG/UL-ASUS_T00F-WW-2.21.40.44-user.zip
[2] adb/fastboot files: from here
[3] device drivers:if you do not have device drivers download and install pc link on pc from asus website,it will automatically install device drivers on your pc.(download from: http://liveupdate01.asus.com/pub/ASUS/LiveUpdate/Release/ZenFone/APP/LinkRim/PCLinkSetup.exe)
IF U R BRICKED PROCEED FROM STEP 2 ELSE FOR BOOTLOOP START FROM STEP 1:
step 1] try booting into recovery and perform a factory rest and wipe cache if this solves the bootloop(in most cases it should).if it still bootloops then follow the following tutorial
step 2]extract the fastboot files on the desktop and paste the firmware(it will be in .zip)in the fastboot folder
step 3]after copying the firmware also extract and copy the recovery.img and fastboot.img file from the firmware into the fastboot folder. (don't remove original firmware zip)
now your fastbootfolder should contain fastboot files+recovery.img+fastboot.img+firmware you dowloaded(compressed in .zip)
step4]boot into the fastboot by switching off the phone and powering it on by power+vol up key until asus logo comes up
if u r returning from some other rom u need to relock the bootloader so scroll some below to see how to relockbootloader.
step5]once you booted to fastboot ,open command promt in fastboot folder (downloaded earlier) by pressing right click+shift in any blank space on folder screen and selecting open command promt here.
in cmd write:
step6]
Code:
fastboot flash fastboot fastboot.img
step7] fastboot reboot-bootloader
wait until reboot is complete then write
step8]
Code:
fastboot flash recovery recovery.img
fastboot reboot-bootloader
step9] now we will be erasing data and cache for a clean flashing
Code:
fastboot clear data
fastboot clear cache
both of them take time and screen may turn off to save power so don't panic
next use volume keys to navigate to recovery and select it using power key .once your phone boots up showing android with belly open symbol press and hold volume up+volume down until recovery menu appears.if that does not open recovery try this:
hold volume down button, click and release vol up button,,,then finally release vol down button.
i admit it brothers,,it is sometimes really difficult to boot into recovery...but keep trying,,it is a bit difficult but is fruitful
if it doesnt appears it may be due to unssucceful flashing, unplug usb cable,force switch off phone by holding power button for few seconds.now again boot in bootloader by power button and vol up key and repeat from :step[8]
once in recovery select apply update from adb
step10] write on cmd
Code:
adb sideload <downloaded firmware name>.zip
for convenience you can rename firmware to kk.zip or any thing you like so command will be adb sideload kk.zip(it may take 15 to 20 mins)
step 11]once thats done select wipe data and cache in recovery and at last select reboot from recovery menu(dont skip this else you may face freezing on welcome screen itself)
hopefully you will boot into homescreen and be patient first bootup may take upto 20 mins.
[UPDATE] HOW TO RELOCK BOOTLOADER{only for zenfone 5 other device users pls google the procedure}
(USE THIS ONLY IF U R RETURNING FROM ANY CUSTOM ROM ITS NOT NEEDED FOR BOOTLOOPING PROBLEM)
hi guys i know u will be needing to relock the bootloader while returning to stock rom..
so what u have do is use the following steps before flashing fastboot.img that is before STEP [5] mentioned above
[1] download this file (its a zip file extract it using password zenfone-five.blogspot.com)...(link=https://drive.google.com/file/d/0B0o7qWuG7vvVRE9CV0hJWGRJS2c/view?usp=sharing)
[2]follow the on screen instructions
after the bootloader is locked carry on the steps from step[5]

1]unbricking
2]returning to stock rom
3]bootloop issues

Device is not detected when trying to flash TWRP

okay hello people.
here is my situation.
i was about to revert back to kitkat from ED300 CM12.1, and i suddenly wipe off and formatted my internal storage.
and now ofcourse i cant boot in and what i did was trying to reinstall TWRP through fastboot and minimal adb from PC.
*i tried to flash Lenovo_A6000_TWRP-3.0.2-0_x64-L_by_SevenMaxs
*i cant go into download mode (vol+,vol-,power) button.
so i went to fastboot mode (vol-,power) button until the 'powerkey long press can reboot phone' appear , and i plug in my phone to pc and when i type in command for -adb devices, no device appear.
figure out it was okay, i go ahead and proceed with - fastboot boot recovery.img command.
then it shows
FAILED (remote: dtb not found)
and im stuck there. idk what else to do, which guide to follow to bring my phone back to life.
i have did hours of searching but nothing works. really need a magic here.
thanks guys for ur time

BTW if "fastboot devices" not showing any devices then try to properly install fastboot on computer."fastboot boot twrp.img" is command for boot the twrp without flashing.
try "fastboot flash recovery twrp.img" .
p.s:-Try to flash different recovery file.It may be corrupted.

Here is the possibilities:-
1)May be fastboot is not properly installed .I gave a link in the previous post for that. "device not found" that shouldn't be appear.
2)Try vol+ +power button
3)Try if stock recovery can be flashed by fastboot.Link.if can be then let me know.
4)If not then run this command in adb
Code:
adb shell
ls -al /dev/block/platform/dw_mmc/by-name
and give a screen shot.

Did you flash kitkat ROM after this or before this fuss?
If Yes, then you need to flash TWRP for kitkat firmware.

download the above recovery and download flashify from playstore . Flash the recovery that you downloaded from above link with flashify and reboot and in the next step you will be in the recovery

well, i think this caused by relocking bootloader after we flash a new firmware. if that happens, just go in fastboot mode by hold power button + volume down, then unlock it again using mi unlock. reboot it..your twrp is back.
no need to enter edl mode & install twrp again, btw thanks..this is helpful

tips to avoid relocking bootloader, when u want to flash a new firmware..just delete emmc apsbot.mbn file inside the firmware using winrar or etc, or u can use psy-man firmware because the emmc file has been deleted

don't flash official miui from twrp (you better do it in edl mode), but yes you can flash custom miui like miui eu, miuipro, multirom, epic miui etc from twrp. and..after u delete the emmc file inside the firmware which is included on every miui rom, your bootloader will be safe

Probably the problem with bootloader file

not a whole lot of talk anywhere else so i'll try here. i just got my kenzo few days ago, jumped the gun and started trying to get twrp on it. i'm assuming the bootloader was locked. As of right now it wont boot up, its in edl mode maybe... red led flashes and i can upgrade driver to 9008. sometimes its recognized by miflash and when it is and i try to flash stock fastboot it gives me an error. i know thats a lot to take in but i'm trying to cover all my bases. the phone came from overseas so sending it back isnt really an option. any help is appreciated.

Does the rom link given here unzips perfectly?
Because i saw in another thread of Lenovo K8note titled firmware, users unable to unzip due to error in system img. Also downloading from baidu needs a user id. If its possible could you or anyone else reading this upload it in some other online storage drive. Im little bit worried about getting a worse situation while rooting. Even if it goes wrong i can use the stock firmware to make it back.

Yes, I think so. Anyhow there is no need to unlock oem again if you are flashing the rom via TWRP. Anyhow let someone confirm about it.

No need to unlock bootloader again if you use fastboot method to flash stock firmware , & for spflashtool I'm not sure but I think it remains unlocked

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 ) ?
