I've seen lots of Android phones that can enter a 'graphical' HBOOT interface. Why SE devices don't?
All we can do is fastboot and CWM.

I was trying to understand what is fastboot. And then I got caught into all that bootloader jargon and couldn't differentiate one from the other. So I have a few questions. If someone could make me understand this stuff...I would be really grateful. Thanx guaranteed:laugh:
1. What is fastboot? When I run fastboot commands through cmd...I get <waiting for device>.
2. How to get into fastboot mode...should I boot into bootloader? How?....I possess a Samsung Galaxy R...very similar to the galaxy s2
3. I know how to get into recovery...I'm rooted and have a custom recovery CWM. Is recovery same as bootloader?
4. Then what is download mode....how is it different from bootloader mode or recovery mode?
5. I tried running fastboot commands through cmd by entering recovery and download mode...but got the same message as in point 1. Whats wrong???

Answers:
1) [Q] What is Fastboot?
[A] Fastboot is a command line tool used to directly flash the filesystem in Android devices from a host via USB. It allows flashing of unsigned partition images. It is disabled in production devices since USB support has been disabled in the bootloader.
2) [Q] How to get into Fastboot Mode?
[A] I have no idea on your specific device, but I would imagine a little Google'ing and you could find the answer. I'm sure it's like any other device: a combination of certian button presses upon reboot or at boot.
3) [Q] Is recovery the same as bootloader?
[A] No. The bootloader, in literal terms, is code that is executed before any Operating System starts to run. The concept of bootloaders is universal to virtually all Operating systems that inculcates operating systems on your PC, laptop, smartphones, and other such devices. Bootloaders basically package the instructions to boot operating system kernel and most of them also have their own debugging or modification environment. As the bootloader kicks off before any piece of software on your device, it makes it extremely processor specific and every motherboard has it’s own bootloader. This is one reason that all Android phones have different Custom ROMS developed due to high variance of processing hardware present on the device.
Your recovery is, as in Android, a recovery that refers to the dedicated, bootable partition that has the recovery console installed. A combination of key presses (or instructions from a command line) will boot your phone to recovery, where you can find tools to help repair (recover) your installation as well as install official OS updates. Because Android is open and has the recovery source code available, building a customized version with more and different options is relatively easy as well.
4) [Q] What is download mode?
[A] Download mode is for when you want to flash a new firmware using something like odin, If you update your firmware using kies, kies will automatically put the phone into download mode, if you use odin you have to put the phone into download mode yourself.
5) [Q] I tried running fastboot commands through cmd by entering recovery and download mode...but got the same message as in point 1. Whats wrong???
[A] You're confused as to what the difference is bewteen fastboot and recovery mode are. Hopfeuly, this gave some clarifiaction...
Okay I am on the EVO 3D running Viper Rom 1.0.0, (which has been giving me problems from the start and I am trying to remove it and revert to stock) running the 1.58 HBOOT, HTC dev unlocked, and S-On
Also i have windows 7 x64
The problem I am having is that ViperRom is not working at all. It's booting and running ok, but it gives me numerous problems, like apps not being able to run, apps not found in google play, and it randomly shuts down if I am doing something, like browsing the web or listening to music.
I have tried numerous times to flash different roms, revert to a stick rooted rom etc. But Viper doens't seem to want me to let it go. The only Rom that works for my Phone is Viper ROm ICS Sense 4.1, 1.0.0
Now my last resort is to revert to stock and unroot, then start all over. But now, adb does not want to recognize my device. I am using ADB from a different computer that I rooted my EVO on in the first place. But it should work. I try and type adb reboot bootloader and it gives me device not found. I manually reboot to my bootloader, I get fastboot usb, and then i type the command: fastboot oem lock to relock the device.
Still gives me waiting for device. I have htc sync, the usb drivers, java JDK, and android adk. But for some reason, the computer does not want to recognize my phone. Any suggestions?
If you really want to revert back to stock then your going to have to relock the bootloader then install the stock ruu. You can then reunlock the bootloader with teh same bin file they emailed you.
the relock you need to press and hold the vol dwn buttn and the power button. then go to fastboot (on phone) Then in the cmd line type
Code:
fastboot oem lock
Do you have all 3 files? adb.exe, AdbWinApi.dll, fastboot.exe
Also, I'm not sure if it matters but are you using a USB 3.0 port instead of 2.0? Perhaps run command prompt as administrator? Just throwing out things to try. Hope they work or spark better ideas.
i couldn't get twrp to work on my xperia zr so i tried this open cmd put the phone in recovery mode i think (blue led) then "fastboot flash boot TWRP+RAINBOW2.8.2A.img" then "fastboot reboot" the phone is dead just a red led and a small vibration when powered up but nothing light up any help ?
edit : i boot it again the Q now is there any way to install this recovery TWRP
Depends on if your bootloader is unlocked. I don't know about the ZR specifically, but the majority of newer Sony devices need either bootloader unlocked or to use a special kernel+recovery combo that must be installed through the flash tool for devices with locked bootloaders.
Hi
I've had some hard time trying to unlock my GT-I9060I's bootloader (so I can install unsigned custom ROMs) but I didn't succeed.
Thins I've tried so far:
Installed Android SDK
Installed ADB and Fastboot drivers
Changed the android driver to Android Bootloader Interface
The problem seems to either be my computer not recognizing the phone in fastboot mode or simply my phone not booting in fastboot mode (even though
HTML:
adb reboot bootloader
rebooted my phone)
How can I unlock my bootloader?
Hi
I’m trying to unlock the bootloader of my H616 device but it’s not working.
I can reboot to bootloader and just see the green android alien but none of the fastboot commands work. I can see the device listed under fastboot devices but am struggling to unlock it.
Anyone have any ideas?
