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
Hi all!
Occasionaly flashed blue spark twrp v41 (for OOS 3.x) while on Sultans ROM with locked bootloader.
No root access, didn't flash supersu. Kingroot and other 'on one click' methods somehow don't work.
Now, when I try to use fastboot to flash recovery it denies as bootloader is locked. When I try to unlock bootloader using 'oem unlock' it tries to boot recovery which doesn't boot (stucks on logo).
Any chance to solve without hardbricked solution?
I'm on OOS 2.2.2 and have done the same thing (flashed blu spark v41)... same result as you though, a phone I can only boot into fastboot mode
This was the advice I was given (from OnePlus forums)...
https://forums.oneplus.net/threads/...lus-logo-help-me-please.462406/#post-15248530
Here are the steps to get TWRP without messing up your recovery partition
>> Grab Bootloader file (emmc_appsboot.mbn) from OxygenOS Lollypop stock rom
>> Place it in Adb& fastboot folder and flash it via fastboot
fastboot flash aboot emmc_appsboot.mbn
>> Now Type
fastboot reboot-bootloader
>> Now temporarily boot TWRP official recovery for OPX with fastboot
fastboot boot "yourTWRPfileNAME.img"
You should be able to boot to TWRP recovery now
After Flashing and stuff reboot to fastboot and
>> Grab Bootloader file (emmc_appsboot.mbn) from Oxygen OS Marshmallow stock rom
>> Place it in Adb& fastboot folder and flash it via fastboot
fastboot flash aboot emmc_appsboot.mbn
Reboot and enjoy

Edit: Maybe you'll need to flash the emmc_appsboot.mbn file from the Sultans ROM though???
The above didn't work for me. I had to UnBrick
You cannot install a recovery on locked bootloader,your phone is not going into stock recovery because of some boot failure, just turn off your phone remove battery if its removable then try again to go into recovery

I have extensively searched this forum and couldn't find to answers to the following!
Looking for experts to guide..
Query #1: TWRP Backup of Stock ROM causes bootloop!
I had unlocked Bootloader of Redmi Note 4 and used temporary TWRP (fastboot boot twrp.img) to take a backup of stock ROM and found that the device cannot boot back into Stock ROM.
I had tried to restore 'boot.img' using the TWRP stock ROM backup (and also from downloaded stock ROM) but that didnt help.
Same problem seen in Redmi 4 as well.
When booted to TWRP using fastboot boot (without flashing), in which partition TWRP is stored (boot or cache)?
After I had booted into TWRP (without flashing), is the backup of boot partition that I took still a stock version one?
Query #2: Relocking and unlocking Bootloader
I had unlocked bootloader using the MiFlash unlock tool (miflash_unlock-en-3.5.1108.44).
If I relock the bootloader using the MiFlash tool, would I need MiFlash unlock tool again to unlock or would 'fastboot flashing unlock' work?
Thank you!

1. That bootloop *probably* happened because you swiped the "allow modification option" in twrp.
(One more advice : in twrp backup you should backup the "system image" and "vendor image" not the "system" and "vendor", If you don't want bootloop after restoring. (Or If you got a bootloop already flash that verity removal zip)
2. You will need mi unlock again.
Hi,
So long story short, I tried to get good phone for someone for a good price, I ordered a Xiaomi Mi 10 from China - But it came with a bunch of Chinese bloatware so I wanted to flash the Global ROM and have Google on there
I added it to my Xiaomi account, unlocked the bootloader (waited 168 hours), then followed instructions from a youtube video (
)
It worked well - I used adb to flash TWRP, and was able to install the Global ROM from xiaomi.eu using TWRP (version 12-11) (filename: xiaomi.eu_multi_MI10_V12.2.9.0.RJBCNXM_v12-11)
This worked well and everything went smooth, and I thought I was done, then I wanted to remove the device from my Xiaomi account, so I did remove the device from my account via Mi Cloud, and then I went to factory reset the phone, and then it just keeps booting into Fastboot.
I tried to hold buttons to boot into TWRP (volume UP and Power) but just goes into Fastboot, I tried to flash TWRP again via adb using "fastboot flash recovery twrp.img" but am getting this error when I run "fastboot boot twrp.img" - FAILED (remote: 'Failed to load/authenticate boot image: Load Error')
Please let me know if there is anything I can do - even to get back to the chinese stock ROM
Thanks in advance
Hi all - I solved the problem by using the Global Fastboot ROM and MiFlash tool - I got a CRC error "update sparse crc list failed" but followed some advice to edit the "Flash.all" script and remove the 2 lines that contain "CRC"
Then the Flash process worked and the phone did boot into Global ROM
The xiaomieu stable version has a problem with custom recovery, so you grabbed fastboot.
if you want to use recovery, you need to boot recovery via ADB with the command fastboot boot recovery ....
Do not use on a stable version of xiaomieu recovery via the restart button to recovery
Actually, one can boot to recovery via restart button, but only after flashing the twrp 3.4.0 little turtle.
However, this recovery isn't able to decrypt the partitions, and could be used for flashing ROMs only from OTG drive.
The one that does decrypt and could be used in "normal" way is twrp 3.4.2.1206, but this one can only be booted as you said with fastboot boot recovery.img
