NexusHD2 Android Forum

I'm running NexusHD2-KitKat-CM11.0 V4.3 on my HTC HD2 1024Mb phone.
The phone has been running fine for the past 1+ month since I flashed it with this ROM.
All this while, I've been swopping out depleted battery with freshly charged battery because my USB port is a little loose & makes charing difficult.
Last night, after shutting down the phone completely and replacing the battery, I could not get it to boot properly to the home screen.
It would stay indefinitely on the cyanogenmod logo screen with the spinning arrow.
I left it in that state for more than 30 mins and no difference.
I've also tried formating cache partition and that did not work.
What else can I do besides rebuilding the phone from scratch?
I've a 1 week old Titanium backup & just created a CWM backup from within recovery.
Appreciate any help & advise to get this work back to working order again.
Thanks!

Remove the battery and turn it on and repeat until the home screen appears.

Thanks for your advise.
I've already done that many times and it was not getting anywhere.
I eventually figured out that it could be caused by bad blocks in the NAND.
There are a few error output from the installation log.

Code: Select all

Formatting /cache...
mtd: erase failure at 0x02140000
Done.
Formatting /data...
mtd: erase failure at 0x03ba0000
mtd: erase failure at 0x05480000
mtd: not erasing bad block at 0x09be0000
mtd: not erasing bad block at 0x09c20000
Done.

I decided since most of the bad blocks are in the /data region, I went ahead and rebuilt my HD2 using /data in EXT4 in the SD-EXT.
Phone is up & running & is working well so far.
And I was able to upgrade to v4.4 too.

Thanks.
Why are your recommending against using Titanium Backup?
I've been using that for all my rooted Android devices & it has saved me on numerous occassion.
I've also used CWM Recovery backup from time to time except that this time, the backup was performed after I ran into that issue not before, so I think the backup is unreliable at best.
After rebuilding my HD2 with /data in EXT4 in SD-EXT, I backup up my phone with CWMR after using my Titanium Backup to restore all the apps & data.

To prevent this problem from occurring again in the future, I recommend that you resize your system partition to 400 MB.

I've already done that as a precaution.
Even though the log did not indicate any bad block error in the /system partition, which was 280Mb, I went ahead to repartition it to 445Mb using HD2 Toolkit before reinstalling the ROM in it's current setup.
