[Desire Q&A, Help & Troubleshooting] s300pmu1:
4. Troubleshooting ROM installation

4.1. It won't flash the rom!

1. Attempt to flash modified ROM without toggling signature verification to disabled

If you modified your ROM.zip file, you have to toggle signature verification off; e.g in Amon-Ra it's in the menu Other\Toggle Signature Verification.

2. Corrupt ROM file

- You may want to check MD5 signature for the rom file just in case (see link to software to check MD5 code in the Downloads section of this FAQ)

- If you modified the rom.zip - make sure you did it without extracting stuff with consequent recompressing; make sure you haven't deleted anything not meant to be deleted

- If you tried integrating kitchen mods into rom.zip file - try flashing a vanilla rom, this way you'll determine the cause (maybe you modified rom.zip incorrectly, corrupting it)

4.2. I'm stuck on first boot!

Usually, failing to flash\boot the rom has the following causes:

1. Incorrect card partitioning - perhaps number one among other reasons.

To check for it, reboot to recovery (if you can't reboot by key combination, pull the battery). Try mounting sd-ext in recovery.

If it fails, this is indeed a problem.

Solutions:

- delete sd-ext partition in any partition manager such as Gparted \ minitool Partition Wizard and recreate it again, then try reinstalling rom by repeating steps starting with step 10 of the above flashing guide.

- if above fails, repartitioning the whole card (fat32 backup may be necessary if you have needed data on it), then try reinstalling rom by repeating steps starting with step 10 of the above flashing guide.

- if all above fails, ask the gurus such as anderl78 or rom-author, and don't forget to press the THANKS button once they have solved your problem

2. hboot - rom incompatibility, such as:

- flashing data++ rom on a device which is S-ON and\or has stock hboot (Solution: if so, S-OFF your device and flash correct hboot)

- flashing data++ rom with Bravo CM7 r1 hboot (Solution: flash Bravo CM7 r2 hboot)

- flashing a2sd+ rom on Bravo CM7 r2 hboot (Solution: flash stock hboot)

- flashing rom on old hboot (<0.93): may take several tries, though I'd suggest S-OFFing as an easier alternative

3. Corrupt ROM file

- You may want to check MD5 signature for the rom file just in case (see link to software to check MD5 code in the Downloads section of this FAQ)

- If you modified the rom.zip - make sure you did it without extracting stuff with consequent recompressing; make sure you haven't deleted anything not meant to be deleted

- If you tried integrating kitchen mods into rom.zip file - try flashing a vanilla rom, this way you'll determine the cause (maybe you modified rom.zip incorrectly, corrupting it)

4. Unrooted phone

5. Other causes

If your problem does not fall under the above list, ask the gurus such as anderl78 or ROM-author in the MAIN THREAD, and don't forget to press the THANKS button once they have solved your problem

4.4. I downloaded the data version and its flashing now and says now flashing leedroid... a2sd+ ?!?!
