You are in luck my friend I am on the case. Okay this is what you need to do.
Note: Steps 2-6 are needed if something goes wrong with the update.
1.
a. Extract the stock recovery from V20A indian (look at my signature). Hopefully you have the V20A kdz already.
b. Place the extracted recovery (should be labeled "3-recovery.img") into the stock_recovery.zip and flash inside cwm
c. reboot, this will take you into the stock recovery and complete the ota update.
2. Download Lelus Fastboot
http://forum.xda-developers.com/showthread.php?p=41768774
3. Install the omap4430 driver twice (in to different locations). This is has to do with fastboot.
Help if you have problems installing the drivers http://forum.xda-developers.com/showpost.php?p=44578108&postcount=34
4. Place cwm recovery image (name it "cwm.img") inside here "c:\fastboot\yours"
5. Right click on start.bat and select run as Administrator
6. Select option #1 (fastboot) and issue the following when everything is operation properly.
Code:
fastboot devices
fastboot erase recovery
fastboot flash recovery cwm.img
fastboot reboot
not needed you have cwm recovery, actually you will need the above (lol) if the update doesn't go through properly.
I'll add some more info, hold up.

Do you have stock recovery img ?
Extract the stock recovery.img first (from the kdz V20A). This happened while doing an ota update right?
Once you have it, we will continue the process.

LG L9 is totally unbrickable phone and it is told many a times before by me and everyone.
If you keep a cool and follow things in this post and few instructions from others from this post, you can still flash any LG Stock Rom on your phone and recover it.

I had stuck on ASUS logo, after I do a lot of researches, a lot of trials and errors for 4 hours. I managed to fix them and I wanted to share how I did here.
Easiest way to root lollipop WW-12.2.2.27
use KingRoot from http://www.kingroot.net/down ,It is android app which will run exploit to root the device successfully.
Not Kingoroot Kingoroot was unable to root. Towelroot v1 works only on Kitkat, but not lollipop.
To boot into fastboot mode
adb reboot bootloader
OR turn off device, press and hold power and volume up, until asus logo appear, and stuck at asus logo, that is fastboot mode, to exit fastboot with buttons, press and hold vol down and power button.
To restore stock recovery and ROM after you install TWRP or CWM, or unbrick device
First, note that stock recovery from http://forum.xda-developers.com/showpost.php?p=59055653&postcount=29, does not work for me (maybe everyone else as well).
I flashed it using fastboot flash recovery recovery.img, when I try to boot into recovery using, vol down and power, then select enter recovery, it stucks at asus logo.
First you need to flash TWRP_2.8.7.0.img from http://quarx2k.ru/asus_padfone_s/recovery/
using fastboot flash recovery TWRP_2.8.7.0.img It will show that flashing FAILED (remote: can't flash unsigned image), it fact, it was succeeded, now you can go ahead and boot to recovery.
Note that this version of TWRP, and 2.8.6.0, and CWM cannot successfully flash stock zip ROM, it may show errors, or when you try to boot the device, it will stuck at ASUS logo. But now, we are going to need TWRP_2.8.7.0 to unlock bootloader.
Let's unlock bootloader
simply flash http://quarx2k.ru/asus_padfone_s/CrowLock_RC3.zip with TWRP
You can check bootloader status with fastboot oem device-info
Before unlock :
(bootloader) Device unlocked: false
After unlock
(bootloader) Device unlocked: true
Let's flash stock Kitkat Firmware
You have to unlock bootloader becuase, well it is complicated.
The only TWRP recovery that can successfully flash stock .zip firmware from ASUS is http://datbak.com/links/padfone_s/asus_t00n_twrp_2_7_1_1.img
But this recovery has another bug, if you flash recovery and try to boot to recovery, you will get blank screen, but TWRP is indeed working, you touch the screen and it vibrates back. Anyway you have tofastboot flash recovery asus_t00n_twrp_2_7_1_1.img because it will be needed later for upgrading Kitkat to Lollipop.
If you don't unlock bootloader, you will not be able to boot into recovery directly without flashing to recovery partition Now let's get into fastboot mode, and fastboot boot asus_t00n_twrp_2_7_1_1.img, by booting into this recovery directly via fastboot without flashing it first, you will not get black screen bug of this recovery., if you boot to this recovery from recovery partition, you will get black screen as I told previously.
Now let's flash downgrade to 4.4.2 firmware from http://dlcdnet.asus.com/pub/ASUS/Mobile_Phone/PadFone_S/UL-ASUS_T00N-WW-99.99.99.0-user-wipedata.zip with TWRP 2.7.1.1.
This is for only WW SKU, not TW SKU. And all userdata will be wiped.
Browse all firmwares and there is TW SKU downgrade here : https://www.asus.com/Phone/PadFone_S_PF500KL/HelpDesk_Download/
Ok, now reboot to system, and yeah, it finally boots now.
The recovery is still TWRP, not stock one, let's upgrade to lollipop and restore stock recovery using TWRP. Simply place http://dlcdnet.asus.com/pub/ASUS/Mobile_Phone/PadFone_S/UL-ASUS_T00N-WW-12.2.2.27-user.zip to root of Internal Memory, unplug usb, press confirmation in notification to begin install lollipop. After device reboot, it will stay blank screen for 5 minutes, don't worry, it is updating to lollipop, after upgrade is done, it will reboot, and recovery will be restored to stock recovery now.
Bootloader is still unlocked.
Another method to root is
fastboot flash recovery asus_t00n_twrp_2_7_1_1.img (recovery is restored to stock now remember)
then flash https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip?retrieve_file=1 with TWRP.
To lock bootloader again, boot into fastboot
then fastboot oem reset-dev_info
But I wouldn't recommend you to lock bootloader, you will lose ability to boot to TWRP recovery without replacing stock recovery, unless you are going to send your device to service center and claim warranty.

Hi im a noob so ill get straight to the point.
You said "Note that this version of TWRP, and 2.8.6.0, and CWM cannot successfully flash stock zip ROM, it may show errors, or when you try to boot the device, it will stuck at ASUS logo."
I have two question as follow:
1. So can i use twrp to flash stock rom or not?
2. Because I'm still at Kit Kat, I dont need to unlock bootloader and flash Kit Kat firmware right?
3. If so, Can I follow the tutorial until flashing the TWRP? but which TWRP that I need to install?
4. All these tutorial to unbrick needs to be done before you brick your phone right? What should i do if i already brick my phone?
Kindly advise.

The only TWRP recovery that can successfully flash stock .zip firmware from ASUS is asus_t00n_twrp_2_7_1_1.img
If you are bricked, but you can still access fastboot mode, then you can unbrick and reflash stock firmware to your phone
First of all, Thank you so much for this GUIDE
Here are my doubts, and hoping for confirmation from you. My Padfone S is running well on latest kitkat firmware, rooted with SuperSu and TWRP 2.7.1.1 installed. Now, I wished to upgrade to Lollipop firmware.
Can I use the TWRP 2.7.1.1 to clean install the lollipop firmware instead of the stock recovery because I wished to wipe date, cache as well as SYSTEM before flashing?
My concern is I afraid if wipe the SYSTEM then the TWRP 2.7.1.1 would not be able to flash the Lollipop firmware successfully. Do I need to unlock bootloader in my case?
If I can do so, then can I still use the Flashify to flash TWRP 2.7.1.1 on the lollipop firmware, or I must use "fastboot flash recovery TWRP_2.8.7.0.img" method.
Thanks in advance for your kindly reply.:laugh:
Bootlooped
When I am upgrading my SuperSU and it requires a reboot,it automatically boot looped itself.
What should I do?

Hi thank for your guidance on how restoring stock rom . Im having trouble detecting my phone when in fastboot mode, as you said to boot up into fastboot hold vol up and power and we will stuck at asus logo , but after i connect my pc and using adb cmd fastboot devices it didnt detect any devices and cant proceed to next step when i need to fastboot boot twrp 2.7.1.1
Currently im using twrp 2.8.7.0 , i want to use stockcrom because i need to use my padfone station (since any custom rom is not compatible with padfone station), any suggestions for this problem ? Thanks in advabce
I tried to install custom rom in my lenovo p70, I successfully flash TWRP and I backup my device before proceeding in flashing this rom in "www.needrom.com/download/vibeui-3-5/". After I backup my device, I proceed in installing the rom using twrp but when it says reboot, my phone stuck in boot logo and keeps on restarting. The "Volume up + power button" still working and I got a chance in selecting recovery mode but when I choose it, it just stuck in boot logo and restart again. I tried flashing the TWRP again but no luck, I can't enter in recovery mode to restore my backup :crying::crying::crying: Please I need help
Assuming the backup via twrp is still in the internal storage, go to fastboot and boot the twrp image (fastboot boot *twrp.img*) and restore.
I'm stuck in fastboot sir. My previous ROM is android 4.4.4 64bit. Can I flash the stock rom using flashtool?

Download ADB and Fastboot tool. Place the custom recovery image on the ADB and Fastboot folder. Turn on the device and go to fastboot then connect it to the computer. Open terminal/cmd: fastboot boot "name_of_the_recovery.img"
It should boot the custom recovery then you can restore your backup.
Or just flash the stock rom if you have it.
I also have the same problem. my stock rom on Lenovo-P70-A was kitkat 4.4.4. 32bit. i tried to install CM-13 64bit by following the procedure on this link: http://www.lenovoroot.com/2016/10/cyanogenmod-130-for-lenovo-p70-fully-working.html . but something went wrong. i flashed P70A_AOSP_5.1_64bit_v2 using SP Flash tool and then flashed cm-13.0-v1-UNOFFICIAL-P70 but when i rebooted the phone, it is in continous bootloop. turns on, shows logo for some seconds then again boot. i can go into fastboot mode but can not get into recovery. prevously my phone was rooted and i made backup with twrp on my usb flash but now how can i restore my backup from usb flash. i can not boot into recovery even from fastboot and can not flash twrp or other recovery from fastboot.
any help would be appriciated.
thanks in advance.
UPDATE: BOOT LOOP LENOVO P70-A PROBLEM SOLVED.
Before when i posted the bootloop problem. i was unable to turn off the phone and without turning off properly I was unable to flash stock rom with SP Flash Tool, but after searching i found this thread : https://forum.xda-developers.com/nexus-4/help/removable-battery-how-to-shut-phone-t1964992 .In this thread I found how to turn off a phone with a non removable battery. During bootloop when Logo appeared i kept press power button at least for 10 seconds and then phone powered off and no more boot loop. so I was able to flash stock image using SP Flash tool. now my problem solved and phone is working fine.
Hello everybody!
The last day my phone got stuck on bootloader screen. It just wouldn't boot the OS.
So I tried to fix that by flashing other rom. I have unlocked it trough MiUnlock.
Flashed in fastboot TWRP(rosy) recovery. It could boot TWRP but after a reboot, would launch MiRecovery.
After that the Android didnt start no more. After a new flash of TWRP I was able to enter recovery. I tried to flash a custom rom. After that the VOLUME UP + POWER wouldnt launch recovery no more (Also VOLUME DOWN+UP+POWER buttons, wont boot the Recovery)
Now i found an EDL mode to flash rom through XiaoMiFlash. Did it, Made the steps from tutorials. That, has changed the device to COM10 in MiFlash which let me try different official roms, and i always get the same error message: cannot receive hello packet, MiFlash is trying to reset status!
Also tried too flash a recovery img.
Tried everything i found on that, nothing worked to get those packets...
My only hope was to fastboot flash recovery TWRP or MiRecovery. And then flash new rom to fix my phone.
Tried many version of Twrp, but no success to actually flash.
I have tried removing recovery via adb and flashing another. Logs shows success but no effect on phone.
Still can't acces recovery mode on my phone.
Bootloop stuck. Shows MI logo and that its Unlocked.
Doesnt work flashing via fastboot - TWRP or MiRecovery images.
My phone is bricked for a week now. Please share a solution if you got one.
SOLVED
Good news. finally flashed chinese version through miflash tool.
had to rename some files from rom.
Flashed through BOOTLOADER.
