no downgrading hboot 0.80 to 0.75 anymore?

[Guest biker200]

hey.

as i seen in the guide how to downgrade hboot, the cid generator site is down for few days.

is there another way to downgrade to 0.75?

thanks.

imy problem is, i had brand new tmobile, 0.75 tryed to root it with r6 for 0.80, now it keeps rebooting it self even after that i instaled the tmobile rom 1.21 for 0.80 and unrooted the device.

so what im trying to do is downgrade to 0.75, install the tmobile 1.15 for 0.75, maybe it will help, before it will go back to htc.

tnx.

First of all..... you've NOT bricked your device!!

Why has everyone jumped on the "bricked" bandwagon?

You can still downgrade to .75, we just need to manually create the file that the generator created.

The easiest way to explain would probably be if you pop onto the irc channel

#modaco at chat.freenode.net

Its quite an easy job :(

I had the same problem, stupidly I kept the R6 Rom on my sd card and used fake flash to flash an extra to the rom and without looking I hit select without reading and flashed the same rom again. In itself shouldn't have been a problem but it was and I ended up in a loop of just before loading then back to restart.

Did you do a nandroid backup before flashing the rom, if you did then its simply restore and that should sort it, if you didn't I bet you wish you did now lol. I hadn't either cause I hadn't intended flashing a rom and its not a mistake I will make again in a hurry.

What I did was use fake flash but instead of going to flash update.zip I did a wipe cache and data leaving it back at factory default, then after completed I did a reinstall of the rom which came out back to normal as expected.

After that Restored with Titanium backup to the backup i take every night and all I ended up loosing was a few hours worth of texts.

If you didn't have the backups then not much you can do apart from a complete wipe now, but loosing data is the least of your worries I guess.

Hope that helps a bit, I'm far far from an expert but trying to learn what I can.

Downgrading to hboot 0.75:

1. Tools needed:

1.1. Hex editor http://mh-nexus.de/en/hxd/

1.2. rooted desire

1.3. misc.img

1.4. attachment flash_image.zip (in german guide: http://www.android-hilfe.de/attachments/ro...flash_image.zip )

2. creating misc.img

2.1. connect the desire to your pc and start a adb shell with:

----> adb shell

2.2. copy mtd0 to sdcard as misc.img

----> cat /dev/mtd/mtd0 > /sdcard/misc.img

3. edit misc.img

3.1. copy misc.img to your pc (or edit it directly on sdcard)

3.2. start a hex editor and open misc.img

3.3. in line 11 is the current version (example: 1.21.405.1)

3.4. change it to 1.15.405.1

3.5. save under a new name and copy it to sdcard

4. flash modified misc.img

4.1. download flash_image.zip, unzip and copy the content to the sdcard (attachment in german guide)

4.2. move via adb to the sdcard

----> cat /sdcard/flash_image > /data/flash_image

4.3. add execute bit

----> chmod 755 /data/flash_image

4.4. flash the modified image (don't forget to change name)

----> /data/flash_image misc /sdcard/misc-mod.img

(4.5. could need more than one try, seems there is no output on success)

5. applied the HTC Bravo WWE 1.15.405.4 RUU to unroot it: http://shipped-roms.com/shipped/Bravo/RUU_...ease_122704.exe

Now it shows hboot 0.75 in fastboot!

Are you going round every forum and dragging well outdated threads back with this nonsense?
