I wanted to resize my ext3 partition to make it a bit bigger. Originally I partitioned the 512MB EXT3 using the last section of the following guide: Droid Den - Phone Guide: How To Add Apps2Sd To The HTC Desire - Droid Den ...when I had a modaco rom. I then moved on to Defrost. This was ages ago. My idea was, nandroid backup (inc EXT), mount in recovery, and create new (bigger) ext via partition wizard (PC application - looked to work really well), restore - jobs a good one. No! So I tried to restore nandroid. Looked to go well, all said restored successfully. Rebooted itself and hung at the HTC screen (not even boot animation). Tried to reflash Defrost. Same So Wiped everything and tried to format SD-EXT. Or so I thought, but clockwork wouldn't recongise the new EXT3 partition. I could not mount it either. Each time "error mounting /sd-ext/! I thought perhaps I had done something wrong, so repeated the Partition Wizard EXT partition creation. The same problem. Except this time it skipped the restore of sd-ext. It actually went through the process last time, appearing successful. I deleted the EXT in Partition Wizard again and reformatted the Fat 32, dropped my important files back on. I flashed an old MoDaCo rom, just so I could get a bootable device and this worked fine. This way I could repartition using original method and if it wiped the SD (including my update.zip for clockwork) I could still get files onto my SD card. This did work, and now I have set a larger sized EXT3 partition. I should have just done this in the first place, but don't really like pushing files out to my device like this. But since I was on a ROM I wasn't keeping and wanted to get back to Defrost ASAP, i did it this time. Of course creating the ext and pushing files out (considering I do not have clockwork flashed as recovery -I have an engineering recovery) I could no longer boot into recovery by applying update.zip (my usual method if not using rom manager). So I had to move all my files back whilst Modaco was mounted. Half way through the transfer, the SD card whimped out and would no longer mount. Reboot. Mounted ReadOnly. GAHHHH. If I tapped the "Mounted read only" notification and quickly clicked unmount SD card in SD settings menu, I could hit the format button. I select "Erase all data" but it appeared to do nothing. Mount and format were selectable in the SD menu, but mount wouldn't do anything. Format just repeated the above. Rebooted. Notification "sd card safe to remove". Clicking mount repeated this cycle. Format then gave me the "preparing SD card" Notification. Plugged into PC and copied the files. Booted to (engineering) recovery, applied update.zip (clockworkmod recovery) and restored my original Defrost nandroid backup. I was trying to decide whether to do this or to just do a flash of the rom and a titanium restore. Was not sure if the ext partition size could cause an issue with the restore of its data. Booted up, saw my beloved normal boot animation. Something I hadn't seen for a while (the BIOS style animation). Hmmm Usually I only see this animation once. BOOTLOOP!!!!!!!! Back into recovery, wipe data. Reboot. HTC white screen only. Recovery. Wipe cache, Wipe data, Format SDEXT. "No app2sd partition found". GAHHH Format data, Format System, Format Data Install Defrost from scratch. Nexus 1 boot animation (Well its a start). Boot - Success. Drop my titanium backups from (i'm not sure when) back on SD) and restored quick system info. Sure enough A2SDStorage "information not available". Reboot into recovery, mount. Partition Wizard only shows FAT 32. Back to push files then. Repartitioned EXT3. Rebooted. Quick system info now sees partition. YAY. Copied Clockworkmod backup files back for one final attempt at getting my last known good configuration back (with the increased EXT). Watched the restore process intensely as my .apk's were restored to sd-ext. Looking good. Rebooted. Watched as my bios animation went to a black / blank screen. This is normal as the animation isn't as long as the boot process. A familiar home screen. Quick System info reporting new size A2SD partition and apps working normally. YES FINALLY!!!!!!!!! All back to normal. Feel free to laugh at my stupidity and ineptitude. I now appreciate that my sentimental connection to my engineering recovery is misplaced. Having a true flash of clockworkmod would have made this slightly less painful but all this is leading to a question. What did YOU do today?
