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
Hey guys,
I flashed the latest official 32.4.A.1.54 (german unbranded) version through flashtool. I now want to install a custom rom but Im suddenly running into problems.
Here is what I did in order:
- Flash official 32.4.A.1.54 via Sony mobile flasher (wiped everything)
- Reboot, go through setup and enable OEM unlocking and USB Debugging
- Check if bootloader is unlocked (it is)
- Flash Zach's Kernel for 7.1.1 through fastboot (fastboot flash boot <name>.img)
- Flash Latest TWRP (tried many many different versions) (fastboot flash recovery <name>.img)
I can not get TWRP to work. When trying to boot twrp through fasboot the screen just stays black and the LED keeps on glowing in blue. Flashing TWRP to boot results in an immediate reboot too.
When I start the phone I can see however that the kernel did succesfully flash.
What is happening here, how can I solve it?
Edit: After doing the same procedure for the third time I could suddenly boot into TWRP. I still can not install it though.
Have you tried booting TWRP by holding volume down on power on?
(fastboot flash recovery <name>.img)

flash twrp to the recovery partition, rather than boot
fastboot flash recovery twrp.img

that is weird
When u are in command screen connect fastboot mode and enter this code fastboot boot recovery.img
If it doensnt restart end enter twrp it mean you should solve driver or flashtool version problem.
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.
