Kembali ke stock hboot dan membuang Eng hboot

Sumber tutor: http://forum.xda-developers.com/showthread.php?t=999796

Sebelum melakukan ini, harap lakukan backup dengan nandroid untuk restore jika terjadi stuck di logo HTC setelah melakukan prosedur ini.

1. Download this zip and extract stock hboot file (1.34.405.5 stock hboot for desire z) and copy to your fastboot/adb folder ....

2. Verify its md5sum of the hboot*.nb0 (md5sum is of the hboot file not zip file) file with this

md5sum = 613ddd077d65d51259795c02ccc2023d

3. Then, from your computer go to command prompt and than go into your fastboot/adb folder

adb push hboot_7230_Vision_HEP_0.85.0005_101011.nb0 /data/local

4. After the file is pushed to the phone verify its md5sum on phone (being extra careful here) using this command:

first write in command prompt

adbshell

and let adb deamon start...... you should see a $ or # depending on whether
you have super user permissions or not....now write


md5sum /data/local/hboot_7230_Vision_HEP_0.85.0005_101011.nb0

and it should show up something like this

md5sum /data/local/hboot_7230_Vision_HEP_0.85.0005_101011.nb0
613ddd077d65d51259795c02ccc2023d /data/local/hboot_7230_Vision_HEP_0.85.0005_101011.nb0


5. This next step is CRUCIAL. You must make sure that you are writing to the proper partition here or you could brick your phone. To be absolutely clear- the partition is mmcblk(zero)p(one)(eight) I'd recommend using an adb shell from your computer (with root privileges: just unlock your phone, run 'su' in adb shell, a window will pop up in your phone asking you to allow it to run, check for it to remember, then allow, the prompt in adb shell will change to '#') for the following command, as it will permit you to copy/paste it: ( if your already seeing # than you already have superuser permissions in adbshell)


dd if=/data/local/hboot_7230_Vision_HEP_0.85.0005_101011.nb0 of=/dev/block/mmcblk0p18


That should do it. You can verify that you have the Stock HBOOT by restarting the phone into the bootloader it should say

something like "VISION PVT S-OFF" and the "ENG" would be gone.

RETURNING TO STOCK HBOOT PART 2

If you dont have the factory unlocked desire z and your phone didnt come with 1.34.405.5 rom out of the box dont use the HBOOT file i posted.

But you can use this method for returning to stock hboot.

STEPS:

1. For that you download the RUU file specific for your phone from the sticky stock roms section.....

2. open the RUU*.exe file and while its open find the temp folder and locate the folder rom.zip.....

cant find the rom.zip????? use this Guide... it helped me find my rom.zip on my windows 7

3. open it with any zip explorer (for some reason my windows 7 was not opening this rom.zip file saying it is invalid i used winrar instead)

4. extract all files to some folder and go there to find the file named something like this.....

hboot_7230_Vision_HEP_0.85.0005_101011.nb0 (your file might have different numbers in the end but its name will start with hboot)

5. generate its MD5sum (there are many md5sum generators online use any you want)

6. than use my guide posted above and use your extracted hboot*.nb0 file and using the name of your file rather than what i posted in commands above.....

Download stock h-boot disini

Kemudian langkah berikut ini untuk G2, jika dilakukan pada DZ maka akan brick!!

1. For G2 Eng-Hboot download this vision.hboot-0.76.2000.zip


2. Now simply extract the hboot-eng.img file from the zip and compare its Md5sum of the hboot-eng.img file with this md5sum 7669AE12DC2FAA10AE555A164980EFD0 and copy to your fastboot/adb folder ....

3. Then, from your computer go to command prompt and than go into your fastboot/adb folder

adb push hboot-eng.img /data/local

4. After the file is pushed to the phone using this command:

first write in command prompt

adbshell

and let adb deamon start...... you should see a $ or # depending on whether
you have super user permissions or not....now write


md5sum /data/local/hboot-eng.img

and it should show up something like this

md5sum /data/local/hboot-eng.img
7669ae12dc2faa10ae555a164980efd0 /data/local/hboot-eng.img

compare the Md5sums here from your phone .....


5. This next step is CRUCIAL. You must make sure that you are writing to the proper partition here or you could brick your phone. To be absolutely clear- the partition is mmcblk(zero)p(one)(eight) I'd recommend using an adb shell from your computer (with root privileges: just unlock your phone, run 'su' in adb shell, a window will pop up in your phone asking you to allow it to run, check for it to remember, then allow, the prompt in adb shell will change to '#') for the following command, as it will permit you to copy/paste it: ( if your already seeing # than you already have superuser permissions in adbshell)


dd if=/data/local/hboot-eng.img of=/dev/block/mmcblk0p18


That should do it. You can verify that you have the Eng-HBOOT by restarting the phone into the bootloader it should say IN Second line "HBOOT-0.76.2000"

and your done

Jika stuck di logo htc setelah restart,ini berarti semua partisi telah di-wipe. Masuk ke recovery (abaikan segala macam error seperti "cannnot mount cache"). Lakukan full wipe lalu wipe cache dan akhirnya wipe dalvick cache dari menu advanced.  Setelah itu restore saja backupan dari nandroid backup (jika sudah backup).
