Hello everyone, i rooted my Evo 3d about 4-5 months ago via HTC unlock method and when i go into fastboot screen (holding down Vol - and Power when phone is off) it says S-ON and all that. (just so you guys have an idea where im coming from)
now the thing is every time i want to flash a ROM or kernel or even go into recovery i have to flash the recovery image via fastboot so i can THEN go into CWM.
The other day one of my friends showed me his EVO 3d and he had an updated CWM recovery that was touch screen based (with bigger options) and he could access it from the phone per-say without having to flash the image via fastboot like i have to everytime i want to update my ROM.
Where can i go about finding out how to update my CWM recovery or should i first UNROOT my phone then re-root it to install this new recovery? My primary concern is just being able to access the Recovery without the need of fastboot.
Im afraid to mess things up since i lost my warranty when i unlocked via HTC method.
I am sorry to say that. You can not downgrade your hboot version and forget s-off (for now) does not matter which c.recovery you use. If you dont want to boot in recovery with your pc , you can use GUI app. Sorry. MY friend

The cwm recovery can be booted without using fastboot too.
I think you always use "fastboot boot cwm.img" command to boot the recovery right?
But if you use "fastboot flash recovery cwm.img" you can always boot it without the use of fastboot.
And if you want to use the recovery like your friends 3d then download and flash this -> http://www.clockworkmod.com/rommanager
Or you can also flash TWRP 2.0 touch screen recovery from here -> http://teamw.in/project/twrp2
I prefer twrp 2.0 than clockworkmod as cwm is littlebit buggy.
NOTE: Even though you can boot recovery from your phone itself without using fastboot, you must boot recovery from fastboot for flashing kernels or ROMS with kernels different than your current one.
I am on a (completely stock) AT&T HTC One (4.4.2) and I was thinking about trying out some custom ROMs. Can I just use the HTC dev tool to unlock the boot loader? How would I root after that?
I am still new to it so that's about as far as I've gotten in the process. Especially since most of the tutorials I've seen are older and do not exactly mention 4.4.2.
P.S. ~ Kingo root seems to have a very simple HTC boot loader unlock tool as well as an easy method to root. I used the root method on my GS4 a while back and it went pretty well. Are there any downsides to using these?

Getting started with rooting and putting Roms on your phone is no time to get Lazy !
The steps are very simple but learning it the correct way comes in handy down the road.
unlock the bootloader at htcdev.com
use the drivers and adb/fastboot I'm posting below
after you bootloader is unlocked
you use fastboot to flash custom recovery on the phone
TWRP 2.6.3.3 is recommend - Download TWRP
The commands to flash it are
fastboot flash recovery openrecovery-twrp-2.6.3.3-m7.img
fastboot erase cache
fastboot reboot-bootloader
Now enter recovery and on Exit it ask to Root the phone
choose Yes - swipe to root
when the phone boots up go in the app drawer and open SuperSU
it will ask to update choose yes and TWRP method of install
Your phone is now unlocked / rooted / with custom recovery
Now is the time to make a backup in TWRP and copy it to your PC for safe keeping. Your now all set to flash custom roms

Alright, thank you very much. I will look into this.
please help me i cant root my device sony xperia z2( D6503 ) and i cant boot into recovery mode
i tried many methods to root my device and i cant do this any one can help me and i cant boot into recovery
i flashed new stock room with flash tools now i have a lollipop 23.1.A.0.690
i have attached a photo of my problem
sorry for bad english
1) Completely and utterly wrong section, this is Original Development. This is a question, it belongs in the Q&A.
2) You cannot use current root exploits to root lollipop. You either have to downgrade to kitkat, root that, flash locked bootloader recovery, and then install a pre-rooted ROM through recovery. Or you can unlock your bootloader, flash a custom kernel with Recovery, flash the SU zip in recovery and then you're good to go. Be warned that you WILL void your warranty if you unlock your bootloader, you will also lose your DRM keys and some functions (although lost functions are debatable). The first method (downgrade) is preferable.

You have to flash a custom kernel what has a recovery in. For example, AndroPlus v50+. And you do realise that now you have voided your warranty and lost your DRM keys? I did explain that in my other post.

If your drm-keys are intact, your bootloader probably isn't unlocked.
You may check if you go to caller app, push *#*#7378423#*#*-service info-configuration. what is written under rooting status?

Well my friend, then you should be good to go download kernel with recovery.
unpack kernel zip and find the boot.img
Use flashtool, connect your device in fastboot mode.
under flash symbol, select fastboot mode. Then choose: select kernel to flash.
select boot.img wich you just unpacked.... done

You can use an app called "root check" to verify root.
---------- Post added at 11:28 PM ---------- Previous post was at 11:19 PM ----------
You should probably use a kernel for 690 firmware if you are on lollipop rom. andopluskernel works great. also with twrp. use v50 or higher.
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.

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"
