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.
Sent from my SM-N910C using XDA Free mobile app
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
No matter how I try to flash the TWRP recovery image to the recovery partition, TWRP gets replaced by the crappy stock recovery!! This is absolutely maddening!
Specifically, it seems that no matter what method to use to flash the TWRP recovery, it gets overriden by the stock loader when the phone reboots.
My bootloader is UNLOCKED and I've installed a custom rom just fine by using the command fastboot boot twrp.img to boot into the twrp image. This is the only way I'm able to use TWRP at all.
I've tried:
fastboot flash recovery twrp.img
Booting into TWRP, and flashing the image over the recovery partition
Flashify to flash the TWRP over the recovery partition from within the rom
Trying to flash cyangenmod's recovery from within the rom (was pretty desperate at this point..)
I've also tried many different versions of TWRP, I can boot into them just fine but none of them stick when I flash them to the recovery partition.
It always says it's successful when I try to flash it, I reboot into recovery, and it boots into the piece of crap EmUI stock recovery screen every time
Anyone have any pointers here? It's not the end of the world but it's pretty aggravating having a completely useless recovery if I'm not near a computer,.
Try using Flashify or Flashfire.
Sadly didn't work. It doesn't seem to matter how I flash the recovery, the bootloader replaces it with the stock recovery when it boots. I'll update the OP to clarify, but thank you
I am having same issue have you found a fix
Have you tried starting completely over? Like, downloading the official MM build (b331, C564D003) from Huawei (Assuming you're on L24)?
On the new, freshly installed ROM, make sure that USB Debugging is and enable OEM Unlock are on in the developer settings.
Then, try flashing this build of TWRP again.
Before rebooting, do a Cache/Dalvik Wipe.
Boot up into the stock rom, then use 'adb reboot recovery' to see what happens next. It should work...
Hi mate,
It'd be easier to help you if you could post a screenshot of your FASTBOOT screen. There will be a line that will say FRP=LOCKED/UNLOCKED something like this.
if it is locked,
you have to install stock rom & enable OEM unlock from setting.
Then relock the boot loader. Then again unlock the boot loader.
For myself, I unlocked my BL unofficially, & this problem occurred . I solved it this way...
Hope it helps.
Cheers!
So I actually tried installing the TWRP a couple days ago. When I tried to boot to recovery with button combination Vol Up+Power Button it always booted to stock recovery. The thing here is that from the fastboot tool when i boot to TWRP with
Code:
fastboot boot twrp.img
after
Code:
fastboot flash recovery twrp.img
it boots to TWRP and everything works fine. However, since that day i tried flashing the TWRP my phone is lagging very much. I tried to Hard Reset it but it still lags seems like there are some bugs and sometimes a "System UI has stopped" error pops up and it suddenly reboots.
First question: What causes the lags?
Second question: if i re-lock bootloader will the problem stop?
Third question: May that be the case that the .img file of the TWRP has been installed but cannot boot so it might corrupt the bootloader re-lock and hard brick my device?
I'm thinking of relocking it with
Code:
fastboot oem lock
Also sometimes wifi suddenly turns off and won't turn on unless i reboot and it doesn't always work and some system apps stop working as well. when i reboot for the couple first minutes the phones works great no lag no bugs, nothing. Plz someone answer asap i'm going to need the phone and i cannot work with all those lags.
Download the latest fastboot stock rom from here : ( not recovery rom, download fast boot rom.)
https://mirom.ezbox.idv.tw/en/phone/platina/
Flash it with mi flash tool and check the option re lock. Or lock something like that. And the problem should be fixed. Your bootloader will be relocked and your recovery partition should go to normally.

If you want to relock your bootloader, then simply flash the official firmware for fastboot, then select the clean all and lock option in the miflash tool, then the bootloader will be locked
