Htc explorer hboot downgrade - HTC Pico (Explorer)

how to do downgrde hboot for pico? pls help. sorry bad englısh.

You cannot downgrade the hboot to a lower version.. AFAIK.

This method may work but I haven't tried it yet. So be careful if you attempt it
1. Reboot into recovery
2. Connect to your PC and enter adb shell
3. Within the adb shell type:
Code:
cd /
cat /dev/mtd/mtd0 > /sdcard/misc.img
adb pull /sdcard/misc.img
This will dump your misc partition on your PC
4. Open misc.img in any hex editor and find your version string in the format x.xx.xxx.x and change it to 0.00.000.0
5. Push the modified misc.img back to the sd card and flash it back
Code:
adb push misc.img /sdcard
cd /sdcard
erase_image misc
flash_image misc misc.img
6. Relock the bootloader using fastboot oem lock and flash an RUU containing an older HBOOT version

And you've tried to boot phone completely, plug usb in phone and pc and in Windows press start, then in the text field right above stay type:cmd and enter. You now are in command line. Now type arbeid devices, enter. The output will tell you if you are in adb mode. If yes, type adb reboot recovery and enter.
I don't have HTC, but this works for my LG o2x, LG 4x, xperia arc s and xperia mini pro. It should work on HTC if normal method are vol- and power pressed and held simultaneously.

Google adb set-up..
Or...
Another idea.. do you have a windows computer?
If so, download this: http://www.androidfilehost.com/?fid=9390275921635705032 (taken from this post)
-unzip the restore-to-ics_win-batch.zip files to a folder on your desktop (no spaces in the folder name)
(don't worry about the restore to ics .bat file - you need the other files in there)
-make sure your phone is off, then power on by holding power + volume down buttons for a few seconds (only hold those two buttons - count to 10 and let go) - this should boot your phone directly into fastboot mode
-connect with usb
-hold Shift and right-click on the new_folder with the adb and moto-fastboot files > choose "Open command window here"
-type in the command prompt:
Code:
moto-fastboot devices
Hopefully it should give you a device id.. If so, then type these two lines (hit enter after each line):
Code:
moto-fastboot erase userdata
moto-fastboot erase cache
Done.. data wiped (and cache, for good measure).
You can type moto-fastboot reboot to reboot your phone normally.
***
Or you could first try with adb by using those files in that same zip (but you probably need usb debugging enabled)..
Just boot your phone normally, then open the command prompt on that same folder as described above, type these lines (hitting enter after each):
Code:
adb shell
su
wipe data
exit
exit

Edit:
1. should I type "adb shell second line [email protected]:/ #" after the new path is set and press enter?

Was much easier for me, don´t know why.
Solution for me:
1. Turn device into Bootloop
2. Connect it via USB (PC founds it)
3. type in CMD "adb reboot recovery"
4. device is in recovery
Requirement is a working Android-SDK.

Going from CM 10.1 to 10.2 upgrade.

So I am currently on 10.1 and am looking to upgrade to 10.2 however I'm lost on one step. I know I have to upgrade my bootloader to the latest stock OTA and I have the file from Asus's site. I also know that I have to flash it in fastboot. My problem is I'm unsure on the command to type in adb to flash it. Is it the same line as if to install twrp just change the file name to what I'm flashing or is there another command.

[UNLOCKED BL] Method 2: Update using fastboot
Notes:
You will keep all your data
This is the best method to update your tablet if you want to keep all your data, and the safest one
Ensure you have the correct drivers for the tablet installed on your computer, or you will have a "waiting for device" error
To update using fastboot, follow this steps:
If you don't have fastboot yet, download it from here an unpack it somewhere on your computer
Extract the Asus firmware file and put the blob file inside fastboot folder
Open a command line on fastboot folder (write "cmd" on Windows search bar at the Start menu, and then
Code:
cd "FOLDER WHERE YOU EXTRACTED FASTBOOT"
, or you can just use SHIFT + RIGHT CLICK on the folder and select "Open command line window here" or something like that)
Reboot the tablet holding the volume down key until you see some icons. Use the volume down key to select the USB icon and then volume up to select it
Connect the tablet to the computer if you didn't do so
Write
Code:
fastboot -i 0x0B05 flash staging blob
, hit enter and wait until it completes
Hold the power button for 10 seconds to reboot the tablet
You are now updated to Android 4.2

Thank you have fastboot and all the files just needed the adb command for fastboot. Also when it's done just type "fastboot reboot" and then it automatically reboots for you. Now this taking it back to stock without losing any user data coming from CM 10.1?

Your phone must be rooted... If you have root your phone follow these steps:
Turn on usb debugging from the developers menu
Then connect your phone to your pc
Navigate to the directory you have installed the android sdk
and open a cmd line window
And type the following:
Code:
adb shell
su
cat /proc/emmc (find the patitions recovery and boot and their numbers)
dd if=/dev/block/mmcblk0p[COLOR="Red"]xx[/COLOR] of=/sdcard/[COLOR="red"]name[/COLOR].img
Where is xx is the number of the partition..!
Thank you very much , every things OK

quick reboot? why
Either your rom has a option in the settings to get a detail reboot menu (with the recovery option).
Either via adb program with your phone connected to your pc
1-Download adb and install adb drivers for your phone
2-extract the files to your c directory in a folder named adb(creat one)
3-once the files are located in c:\adb go to start menu then search for cmd
4-type in
cd c:\adb then click enter
5-type in
adb devices it will show the connected devices
it should be bunch of numbers
6-if you can,t see them it means adb drivers for your device are NOT INSTALLED
7-THEN FINALY IF YOU WANT TO REBOOT
Boot loader
type in
adb reboot boot loader
if you want recovery
type in
adb reboot recovery

Go into the settings of your superuser app and select "full unroot"
