Stuck in recovery mode? Please help !!

Hi,
I was on stock bootloader and stock OTA 4.03 ICS rom. I wanted to upgrade to jellybean rom from tegraowners. I am now stuck in recovery mode.
Here are the steps i did.
1) rooted my A500 succesfully
2) With the Blackthunder APX flash tool i flashed in auto mode the Skrilax_CZ V8 bootloader (with multiboot) also succesfully.
3) Then i flashed with ADB.exe the 1.8.1 Touch recovery image that also went well and succesfully flashed it.
4) Booted in recovery mode and wiped data.
5) Went to install from external zip the latest jellybean rom from tegraowners wich is ofcourse on my sd card.
6) It started to formatting my system partition ( i think it was on 7%) and then it suddenly restarts my tab.
Now the only thing i have is power + -VOL is my recover mode and power + +VOL is my other menu i have wich contain the fastboot menu.
From there i am stuck and don't know what else i can do.
I do have my UID number and SBK.
Here is a screenshot of what i have in recovery mode:
Thanks and hopefully someone can help!
You will have to do a "real" data format. And for more help with ROMs from "other" forums you should ask on those "other" forums.
You will find the moderators here do not condone those "other" ROMs.
Perform a real format, then flash a ROM again (you'd better go to Tegraowners.com for more support), but if the problem persists then it may be a bad download, which means you have to download and flash your recovery again. However at TegraOwners you can also find the latest TWRP recovery.

Help! Cannot access recovery after flashing rom

Hi guys,
I was on android lollipop with a custom rom ( ressurection remix )
I flashed to marsmallow, ressurection remix custom rom.
I followed the instructions and flashed bootstack, then flashed rom and finally gapps.
The problem is gapps are not working and now I cannot access recovery.
I tried to adb push a twrp recovery image.
Now when I try to reboot to recovery I get "boot certification verify" error.
So current status:
-Phone boots normally but no gapps. Get errors for them, don't have even the keyboard app.
-I can see my phone when I plug it with usb on my pc.
-I can access download mode with volume up and power button.
-I have a nandroid backup from the previous rom.
-I cannot access recovery.
Is there a way to install recovery again?
If not, do I have to do this http://forum.xda-developers.com/showthread.php?t=2432476 ?
Also my phone is an international one, If I have to install tot which should I donwload?
Any help appreciated, thank you
You don't have enabled debugging mode on system?
Nevermind I followed the tutorial I posted and managed to get back to stock kitkat.
Now I have a other problems with installing custom rom again but I can at least get into recovery and have a functional device

d801 boots to cm13 but no recovery and no download mode.

I flashed to cm13 nightly 20160302 and my phone boots to cm with no problem but now I am unable to boot into recovery through any method with twrp 3.0.0.4 or any twrp version I tried inside of twrp manager or flashify, I am put into fastboot mode when trying to enter recovery with 3.0.0.4 and a few other I tried while other versions give me unsecured boot message. When trying to go into download mode I get the first download mode screen and then the screen goes blank and brings up 15 system partitions on my pc with only one partition containing a folder called image with a bunch of files. The phone is detectable through adb and as a storage device on my pc while booted into cm and while in fastboot mode the phone shows up as marshal london device- marshal london bootloader interface in device manager with no storage.
I planned on going to cloudyg2 but now I'm thinking about just going back to stock, would I be able to use the lg flash tool to get back to stock? Or possibly use adb recover to stock or use adb sideload to flash the default lg rom?

Having the same issue, after flashing a custom Android 6 rom I'm now stuck with Marshmallow.

Try this to unbrick your phone: http://forum.xda-developers.com/showpost.php?p=66894780&postcount=5
Then try this to downgrade. http://forum.xda-developers.com/zenfone-2-laser/general/guide-downgrade-zenfone-2-laser-to-t3382172
Hello and thank you for your answer
I try out your solutions yours I know you
by cons when I flash the official android 6 it makes me when my phone boot " cant read boot" and I can not find the boot image in file setting has android 6 days
Thank you and good day
I just tried the tutorials its does not work ... I'm still stuck on the Asus screen ...
if you stuck on ASUS logo screen, boot twrp once, it would solve this problem.
download stock from asus site, and flash with stock recovery.
twrp didn't support stock firmware.

Stuck in a boot loop and can't access recovery mode

So I flashed a custom rom and it required a specific TWRP recovery. But after installing the custom rom I had to install another TWRP recovery otherwise it wouldn't boot into OS (this recovery was probably unsupported and thus my phone was forced to boot into OS)
So every time I wanted to boot into recovery mode I had to use an app like flashify and flash the first recovery to boot into recovery mode. And after finishing I had to flash the "unsupported" recovery again in order to boot into OS.
Now with the "unsupported" recovery, I installed Xposed and some modules and then restarted the device. And..........boom! The phone is stuck in a boot loop! And I can't even boot into recovery mode.
Now here's the other nightmares I'm getting:
1. Cant use ADB to flash a new recovery because my device is "unauthorized" and in order to fix that I need to go to developers option which is not possible (because of boot loop)
2. Uninstall Xposed: button combinations aren't working and I cant go to recovery mode to flash the uninstaller zip
3. vol up + vol down + power button doesn't open recovery because the recovery is "unsupported"
4. Can't even boot to fastboot mode by holding vol down + power. It tries to boot into OS and starts boot looping
5. Can't use sp flash tool to flash stock rom or recovery because whenever I connect the phone to PC, the phone tries to boot into OS and....you guessed it starts boot looping.
Now I'm out of ideas and really depressed. If anyone can help me out with this I'll be grateful forever.
My device is: Lenovo k4 note
Chipset: MediaTek MT6753
Currently on this recovery: https://androidfilehost.com/?fid=673368273298981920
Got this recovery from here (recovery2): https://forum.xda-developers.com/k4-note/development/unofficial-resurrection-remix-5-8-2-t3570195
Thanks!

I think the pc cant dtect my device same problem bro after installing new rom it keeps on rebooting after the lenovo logo. Cant also access the recovery mode. Please help me
Bro I'm not an expert. Someone from XDA discord server helped me with this. And I actually forgot the exact thing I did to be honest. I downloaded the sp flash tool on pc and downloaded the stock rom. Then flashed it to the phone. You have to connect your device via USB before. For a detailed guide you can search on YouTube with something like "how to flash stock rom via sp flash tool"
Or ask in the discord server. They will surely help you.
How did you flash that? Can you please explain step by step
Check this link: https://firmwarefile.com/lenovo-k4-note-a7010a48
You can download the stock rom from here. And there is also a tutorial on how to flash it. I followed it. Hope that helps!

Thanks, the problem is my phone is struck on the Lenovo logo, it's not turning off but my computer deducted it as Lenovo device
If ADB can detect your device then you can just flash a new recovery and you should be fine. But as I said I'm not an expert so I'd suggest you to ask for help on the XDA discord server. That's where I got help from.
Did anyone found the solution?
Thanks
Can any one find the solution of that problem , because my lenovo k4 note also stuck on boot looping logo... and vibrate like bootup time
