[Q] Can't factory reset, gives strange error in CWM

I have a US Verizon launch day Xoom that has been rooted since day one. It has been trouble free until now. I recently attempted to upgrade to 2.1 Hammerhead from MantaRay and I got this error in CWM verTiamat R4c-100611 while I was doing a factory/data reset "Error Removing /data/data/com.google.android.location/file/cache.wifi."
I noticed the error but rebooted the system anyway. When I rebooted I was now on Hammerhead 2.1, but noticed several problems. One being I lost function in the Home softkey. I also noticed all my apps and data were still intact as I left them on MantaRay. I like to start fresh with a factory/data reset whenever changing roms to avoid issues so I went back and attempted another wipe and flash of Hammerhead. I got the same error in CWM verTiamat R4c-100611. I rebooted to the same problems in the ROM.
Thinking it might be a problem with the recovery, I reflashed CWM verTiamat R4c-100611, flashed Team Rouges CWM v1.0, and finally reverted back to CWM verSolarnz 120511-2030, and got the same error every time I would attempt a factory/data reset.
I then attempted to do a factory/data reset from within the privacy menu in the ROM. I got the screen with the android and the triangle/exclamation point overhead when I tried. I also unistalled a few apps and cleared data on the google ones. No matter what I do I can not erase the data.
I did some searching around but could not find any info on this specific error. Im hoping I missing something and it is an easy fix. I'm running out of ideas tho. Any advice would be much appreciated!
Pic is of the error message I get no matter what recovery I use.

That is strange and troubling, if indeed this problem just came out of nowhere. I know that you can wipe data in fastboot, though I can't remember the exact syntax right now, but it should be available.
On edit: try: fastboot erase userdata. & fastboot erase cache
I think you do need to wipe/factory reset between Manta Ray and Hammerhead as the framework was changed/fixed, among other things.

Thanks Okantomi! Your advice worked perfect.

[Resolved] [q] formatted samsung epic 4g touch need help restoring please

Hello
Today I was upgrading to the latest starburst rom...this was not the first time I upgraded roms and i did the exact same thing I had done in the past which included wiping data wiping cache wiping dalvik and then flashing....
when i did this and restarted my phone it wouldnt load past the boot screen...after the boot animation the phone stayed black...i repeated steps 1-3 again hoping i just did something wrong...but still nothing
i went back to look at the directions and i say that the developer said to format the system under mounts and storage...in bolded font...i thought maybe thats why it wasnt working so i did just what he said...
now when i load my phone it doesnt load at all and when i open cwm i get a string if e: errors basically saying that it cannot find the drive
if anybody has any advice on how to recover from this I would be extremely greatful

Im having the same problem cant figure out how to fix it.

[Q] Wifi XOOM 3.2 boot loop help!

First off, I have done a search and read dozens of threads, none of which solved my problem...
I have a wifi xoom, which I rooted many months ago without any problems. Recently updated to 3.2 like a month ago or so. I have not made ANY changes within the last month, and the tablet has been working perfectly.
A few days ago, I left the tablet to charge. Once charging was complete, I turned it on and its stuck on the boot animation. I just keeps playing over and over again, I've let it sit for 10+ minutes, with nothing happening...
I tried removing the SD card then rebooting, and its the same result....
Please help! If need be, I can go back and look up all the exact steps I've done to root and get it to where it is today. Like I said though, it has been working perfectly, and I have not made any new changes in at least a month... I don't see why this would happen all of a sudden...

Have you tried to reinstall firmware?
Regards.

No need to panic.
When you rooted, did you install CWM Recovery, and if so, do you have a recent nandroid backup? Have you tried rebooting into recovery?
What steps have you followed to get out of your bootloop?

Yes, I have Clockword Mod Recovery 3.2.0.0 R4c 100611-1150
Upon attempting a restore everything appears to work properly until the end when it gets to restoring data, I get an error, regardless of which restore image I use(I tried all the ones I have). It reads as follows:
"Restoring data...
Error removing /data/data/com.noshufou.android.su/cacheError while formatting /data!"
I also attempted a clean wipe/factory reset with similar unsuccessful results. I get an error during formatting data, which reads:
"Formatting /data...
Error removing /data/data/com.noshufou.android.su/cacheFormatting /cache..."
The rest of the formatting appears to run successful for /sd-ext and /sdcard

Have you manually tried to format the system, cache and data? This can be done from the advanced menu.

From the advanced menu I see:

Sorry, we're forgot talking about Cwm. It's under mounts and storage.

Still the same result as before... I went to mounts and storage > format /data
"Formatting /data...
Error removing /data/data/com.noshufou.android.su/cacheError formatting /data!"

Try format system first then data and cache.

My suggestion would be to go back to stock and then re-root. You can find the stock download on the Moto Dev home page.

Thanks everyone! I was hoping I would be able to fix it without going back to stock, but since I was unable to I just went that route.
Going stock worked, and I am back to where I was before, so thank you for the advice! In case anyone else may have this problem, this is what I did:
Went back to stock using this: http://forum.xda-developers.com/showthread.php?t=1049485
Then rooted using this: http://forum.xda-developers.com/showthread.php?t=1242241
Then got back to 3.2.1 using this: http://forum.xda-developers.com/showthread.php?t=1278214

Infuse stuck in boot logo loop

My infuse is rooted with zues. A few weeks ago, it was stuck on the samsung boot logo and it keeps looping. I wiped data and cache and installed zues again and it was fixed. Last night, this happened... so my phone turns on for 2 minutes max, then turns off and starts the loop. I can only keep on for 2 minutes before it starts looping again. by saying keeping it on for 2 minutes, i mean everything works! talk, text, games, ect...
so i turned it off, went to clockwork or root menu, whatever you guys call it, and i wiped data and cache. Whats weird is that even on boot menu or clockwork, it still wont stay on, it keeps turning off and turns on and loops!
i installed zues again, still turns off and loops
next step? is my phone dead?

Did you have any undervolt settings applied?

The phone is not underclocked, it is not overclocked. It was rooted, I unrooted it. its currently unrooted absolutely factory stock and still doing that. What can I do to fix this?
warranty is over as of 3 months ago

Forgot to mention the most important thing!!!
When I am on the phone with someone, it works perfectly forever, as soon as i hang up, it ends the call. this key thing might help someone find the solution!!

Don't panic just yet... I doubt your phone is dead.
You say you've "wiped data and cache". Are you also making sure to wipe /system and Dalvik Cache?
Try flashing Zeus again.
Boot to CWM, Wipe EVERYTHING (/data, /cache, /system, Dalvik Cache). (Alternatively, get "Clean Wipe" from Qkster's Scripts and flash with CWM to easily wipe everything.)
Flash Zeus and go.
If you're still having problems, perhaps try a different rom?

okay, I read everything you guys wrote.. This is where I am, I am open to suggestions
I am on the stock rom and unrooted. Phone still boot loops. What should I do now? Step by step instructions would be great. Im unrooted, so should i root again? even though im having this problem?

bump! really need help with this guys!

Have you tried going back to stock?
If it keeps looping while on download mode then I would say you are dealing with a hardware issue.
Sent from my sweet & buttery Infuse

It just came to me that it doesn't loop in download mode. It does loop in clockwork, I flashed the stock kernel using ODIN and went completely stock through ODIN.
How do i fix this? i'm pissed that i had it for a year and three months and right after the warranty ended, the phone stopped working! Samsung never again unless this issue is fixed

I'm a newbie to flashing, so take it with a grain of salt. At least two more things seem worth trying to me:
1 - Try factory data reset (assuming you already tried the wipe Davlick and wipe cache). I'm not positive what this does, but I think you may lose some of your data if it's not backed up.
2 - If that doesn't work, try qkster's Heimdall UCLB3 stock (since you can get into download mode...shouldn't be a problem). This is complete back to stock so should be able to clear any software problem I'd think. I know you may think it's redundant since you are already back to stock, but worth trying imo since some things just take more than one try, and you may have had a bad flash the first time around.

Why zeus? try latest ones with jelly bean
Hey,
Try other roms based out of jelly bean. They are pretty stable. CM10 with 09/14 build is the latest
Here are the standard steps if you have CWM enabled.
1. Factory re-set (only when switching between different roms).
2. Cache partition wipe
3. Dalvik Cache wipe
4. Install the zip file
5. Re-start and wait until it re-starts. Initially it will take some time.
I have tried various roms and versions as well. Best would be the CM10 Jelly bean.
Thanks Kran.

[Q] [Help] Stuck on HTC boot screen, other issues in thread

(Just wrote a detailed post and when I went to post, it said I wasn't logged in and erased it...will give a quick run down and can supply more detail where needed as I work through fixing my phone)
Stuck on the white htc splash screen is my most recent problem. Sometimes it gets by that but then boots into recovery. I think bananagranola has the solution in their sig to flash a boot.img. and think I'm comfortable with how to do that, just need to find that file (in the ROM zip?)
What led up to this.
Successfully unlocked and flashed to CM7 back in late Jan/early Feb.
Started experiencing random freezing about two weeks ago.
A week later (last weekend) flashed Jellybean (R10). Worked great for a couple hours then started having the same random freezes.
If things froze I'd have to remove the battery and reboot. After a day or two of this though it'd get to the point that even that would leave me on a frozen jellybean boot animation. So I'd go and factory/data reset in CWM Recovery, wipe cache, wipe Dalvik then reflash the ROM. and I'd be good for a little while more.
Tried flashing back to CM7 but Recovery didn't like the file (it has a good MD5 when checked) Had tried my restore point from early Feb before to no avail, so decided this morning to try other restore points from the last few weeks, right before and after switching to JellyBean. They got further, the first step is something with boot then something with system. It failed on the system part. OK...so I wiped and reflashed jellybean again, and now I am to my splash screen freezes.
I should have asked for help much earlier (lesson learned!) but here I am asking now...what's the first step.
Do I test out and see if I hang on the splash screen again. I haven't turned the phone on in about an hour. Worried of screwing it up more.
Thanks all.
TL;DR Believe I'm stuck on splash screen and know solution to that. Have had phone flashed with new ROM with no prob for months, recently freezing, regardless of ROM. Hoping for advice on getting things working again, starting with whether fixing the splash screen thing first is where to start

splash screen issue seems fixed
Seems I fixed the issue with the splash screen. Booted into recovery and reflashed the Jellytime ROM.
Got all the way into Android. after a few minutes I rebooted into recovery and loaded the gapps. Rebooted, it updated apps (not downloading, the popup that says it updates) and was setting up my account when it froze again as I entered a wifi password. Pulled the battery and tried again, got through that and all the way to the lock screen. froze shortly after that.
Now when I reboot, it locks on the boot animation. The Jellytime screen flashes the brightness as few times as things are loading. after the 5th or 6th flash it just sits there frozen.
a new SD card is in the mail, so I may post again when that arrives to see what I can do with an almost clean slate.

That doesn't sound like an sdcard problem. Are you full wiping?

I'm wiping data/factory reset and cache as well as the dalvik cache.
The steps to flashing a ROM by sashank at link mention to format /boot and /system. I didn't specifically do those...but don't see the option for /boot in any menus I've checked.
A week or so ago I was beginning to suspect there was an issue with the memory but I never found the right search terms to find out how to do a memtest if that's what would have found any problems. Yesterday I did come across some discussion of a corrupt partition/bad chips in some HTC devices. I followed the directions there and through adb ran dmesg | grep mmc0 and the output was similar to the 'normal' one given and showed none of the messages they claimed to indicate a bad chip.
I'm not too concerned with any data from the phone...I backed all that up long ago and the rest restores from my google account. So if I getting things running would normally raise concerns of lost data, that's not an issue for me.
Thanks for taking the time to read. I try to be brief...but don't want to leave anything out.

Wanted to update here before trying to start a new thread and clogging up the board. The title of this thread is not up to date though.
I can hboot just fine and boot into recovery just fine. My phone is unlocked and rooted, ENG S-OFF from when I used AAHK quite a while ago.
When trying to navigate from menu to menu in Recovery I will get the following error messages (best I remember from last time I was in there, I've let the phone be for the last 2-3 days now)
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
This doesn't show up at first though, only after I do a Wipe Data/Factory Reset. And if I understand correctly, that wipes /cache so maybe that's causing these errors?
Anyway, after wiping the dalvik cache I can flash a ROM, I've been using Jellytime, I haven't been able to rollback to CM7, not sure why not.
Jellytime will run though...at first! the first couple of boots I can get in and get through registering my google account and have it begin restoring apps if i make that selection. The time I have to work on the phone before it freezes gets shorter and shorter though. I have to remove the battery to get it to reboot. Eventually I am left with the phone hung during the boot animation. I've left it for over an hour before...it's definitely hung there.
So my reading leads me to believe corrupt partitions. I'm not finding a lot on what I should do to reformat and maybe repartition or whatever I may need to do to recover a functioning phone. I don't care about any data on the phone. I just want to get things working again. I ended up getting a new SD card during all this that arrived earlier. If I can get my phone working, I'd prefer to use that from here on out too. I can use the adb in recovery mode just fine if that's necessary to rejigger things to work.
Can anyone help reset my partitions, if that's what this issue seems to be? If not...any ideas?
Thanks.

Yes. Everytime I've flashed, I've followed:
wipe data/factory resent
wipe cache
wipe dalvik cache
unless there's more I can do.

OK, I'll give this a try. The issue with the freezing is why I moved from CM7 though (which had been stable for four months) so it's reproduced itself in different ROMS. I'll post back once I give this a try. Thanks.

I gave Android Revolution a shot. During the flash it gave a message which might also be why I wasn't able to flash back to CM7. The MD5 did verify.
Code:
assert failed:write_raw_image("/tmp/boot.img","boot")
When I went to reboot, I ended up in Jellytime. Of course I had to sign back in to google apps and those things were reset from the dalvik wipe. Shortly there after the phone froze.
On reboot I tried a logcat. Didn't get it right from the start (you can send the command during the boot animation if I read correctly) but captured the failure of things. It's back around the 09:02 portion of the log. To my eyes it looks similar to others I've collected. Especially the message
Code:
Fatal signal 7 (SIGBUS)
though I haven't been able to figure out much about that, or identify what it is before that that could give another clue as to what is screwy since that's maybe (Probably?) related to the flashing issues.
