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.

It wont, using files from this thread might brick the device.

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
Hi, i've had my Z2 two years now and I've rooted, UB and installed roms on it many times but for some reason I can't get into recovery anymore. I flashed a different ROM a few months ago to try get it back to stock but since then, no recovery!
I've flashed the TWRP 1 click installer (only seems to work on laptop, on PC I get waiting for device but it says it worked on laptop) but still I can't get into a recovery to flash a custom rom.
Any ideas? How do I get recovery back? Please be a bit simple with me, i've googled it and just get overwhelmed by the info so figure I should ask and find out what actually applies to me..
Thanks.
David
If you have flashed a stock rom, you probably have locked your bootloader, try this (hope you have done a TA backup the first time you unlocked the BL...):
Download the Androplus kernel in development section, unzip it.
Then, download and use flashtool (install the drivers if need them) to unlock your BL again (BLU button).
Once you have unlocked it, disconnect the phone from the computer BUT DON'T BOOT IT.
Close and reopen flashtool, and select fastboot mode from flashtool and use the kernel flash option.
Select the boot.img you have unzipped from androplus (change the file extension to .img), and your are done.
Disconnect, reboot and you will be able to access the TWRP recovery from the kernel when you see the led, then flash a stock based custom ROM (with recovery), or CM one, try to have one of them downloaded and placed into your ext-sdcard.
PLEASE! My English is not good enough to explain this in a better way, if you don't are familiar with flashtool, fastboot mode or you don't understand any of the steps, wait for a better explanation or read a lot about it BEFORE doing nothing.
PS. Your internal data probably will be lost, make a copy of all your photos, docs, etc. You can relock your BL if you choose a stock based custom rom like eXistenZ, just restoring your TA backup after flashing it.
have u try flash via adb fastboot? it's easier when u have UB, try erase it first, "fastboot erase recovery" then flash the img (the latest twrp img is available on their site) "fastboot flash recovery recovery.img"
Hello, I'm kind of new at this (this is my first post) so be gentle
So, the last few days I've been trying to install a new rom on my phone (Redmi Note 4X) and the problems started with the model. I only seem to find Redmi Note 4 roms, and as I've come to find, mine is supposed to be the mido one (correct me if I'm wrong though). I have unlocked the bootloader, I have installed and enabled the fastboot on my phone, so the next step was to install the latest TWRP.
There came more problems; I tried doing this through the app and it just wouln't flash it. So I found a guide on how to root my phone and install a new recovery through adb and I followed it. It didn't work. I couldn't find the right twrp version for my phone. When I finally did realise my phone needed mido, I found the latest from the TWRP website. It wouldn't load through adb again. I found a thread about a fixed mido version, which finally worked for me. But my brother who was helping me, and isn't as much of a noob as I am (he has flashed rom and recoveries many times on his Nexus 5X), decided that I necessarily need the latest twrp if I'm going to flash a new rom, so he flashed the new twrp through the old one, and soft bricked my phone (I think). So I'm searching for a guide to unbrick it. (Which I can't seem to find to work at least).
To conclude;
I have unlocked my bootloader
I have access to the fastboot
I tried to flash a recovery
I failed many times, but I managed it
I flashed the latest twrp and bricked my phone
I don't have access to the recovery
My phone is still on a bootloop
I am not sure about which phone model I have
Help!
Thanks in advance.
1. Just check your phone model on its box. If its Snapdragon version (Mido), then just install it via fastboot. (code: fastboot flash recovery twrp-midoxx.img). If you are success, then try to reboot to recovery (fastboot boot twrpmido-xx.img). After booted, then you just manage to rom.zip you want to install. If you don't have it, then download it before from your PC and push it to your phone. Or just enable Mtp checklis from TWRP n copy that file to your internal phone/sdcard. Wipe all/factory reset except internal storage. Then you dan install rom.zip normally. N reboot. (Note: if you are on MIUI and wanted to always stay on it, just flash the file called lazyflasher.zip. n' wipe cache n art cache only then reboot). Flashing custom recovery on stock MIUI Will manage the device Going to bootloop)
2. If you have mediatek version (nikel), searching the fastboot Rom from miui website and flash it normally via fastboot. (SP Flash tool)
Warning: flash the wrong rom file into wrong phone Will make your device brick. So becarefull n knowing what model/code name you have.

Hello and thanks for the reply. I have the snapdragon version, but all I'm asking is how am I supposed to flash the lazyflasher without accessing the recovery? Through adb?

Firstly, enter fastboot mode on your device. Connecting to pc and flashing the twrp for mido. "fastboot flash recovery twrp-mido.img". Then boot to it using " fastboot boot twrp-mido.img". Then you will enter the recovery (twrp) in a second. Copy the lazyflasher into your phone (enable mtp first in Mount option in twrp) that you downloaded from pc. Just flash the lazyflasher.zip and reboot.
And why you don't want to flash lazyflasher when it very easy to flash it using recovery twrp? adb? You mean android debugging? Actually, you cant flash a .zip file into your system partition except through fastboot mode. However, fastboot mode (in cmd) only recognize a .img file. I just try to tell you the easier method to make your device boot up.

As I said above, I can only access the fastboot, and I get errors in the adb when I try to flash the twrp image.
