[Q] how do i wipe cache via adb?

I'm trying to load different Tom's and nothing has worked. Running darchdroid 2.8 now and whei think nothing is installing cus I can't wipe cache via recovery. It tells me to wipe via advanced and I don't know how or the commands. Is this probably the reason I can't get any other Roms to load?? Please help!!

Dalvik Cache?
Just do a system wipe. Most ROMs wipe cache when they are flashed (causing a long boot time, which makes most ppl think it isnt working )

If you're using recovery Amon_RA v. 1.5.2, it still does wipe dalvik cache through the recovery console even though it tells you "run dalvik wipe via adb!". That is merely an output error from the recovery console, it still actually does wipe your dalvik cache like it's supposed to, it just outputs the wrong text string when it's finished. So that is not your problem installing ROMs, it must be something else. What steps are you using when trying to do this?

I tried installing a couple froyo roms.did system wipe then tried cache and when I tried the Rome I got status 7 and some unsigned error

Please tell us exactly what steps you did, in order, so that we know if you are trying to flash a ROM correctly. Also tell us which recovery version you're using (should say at the bottom of the recovery screen).

Anytime I go from sense to any aosp Rom then back to sense, I have to reformat and reparation SD card. Then just drag items back into SD, wipe, and reflash. All will be right and make SENSE.

Check to make sure the ROM is from a good source... if it's not signed then it won't be recognized as valid.

[Q] Whats wrong with my HTC hero?

So I used to have CyanogenMod running on my phone, but it was messing up so I decided to flash the FroYo rom. My hero is sprint and the rom was for sprint phones. But when I flashed the rom my phone wouldn't start up. It just stays on the big "HTC" screen. Ive tryed everything. Any help?http://media.xda-developers.com/images/smilies/frown.gif

Did you wipe (everything!) before flashing the other ROM?

As andythegreenguy asked, did you wipe everything prior to flashing?
Also, how long has it stayed on the HTC screen? Booting a new ROM for the first time can take as long as 15 minutes...

What is the correct procedure to wipe everything off? If I plan to reinstall the same ROM?

Boot into recovery, and do a full factory wipe

Getting stuck there is a bootloop.
It's usually caused from not wiping the cache(s).
New Rom:
(Boot into Recovery)
Wipe Data/Factory Reset
Wipe Cache
Wipe Dalvik
I like to wipe Batt Stats but you don't really need to.
Just Factory Reset, wipe both caches.
I assume the recovery is similar to the evo's, I've never seen the hero's recovery so it might be different.
A new rom will take a little longer than usual because it needs to rebuild the caches while its on the HTC screen.

[Q] Why clear Dalvik and cache?

So every single rom for any phone I've seen says to clear the dalvik and the cache (or maybe its just the "dalvik cache") but when I went from stock to Thriller, I forgot to, and nothing went wrong. In fact, all my settings and apps were all intact from the previous stock rom.
I've considered that the only other phone I'd done any flashing on was a backflip, without Apps2SD and maybe that's why all my apps and settings were intact, so that still leaves me with the question: why clear it?
This may be a noob-ish question, and I apologize. Thanks for any help!

If there are any compatibility issues between the apk dalvik cache of your previous rom and the apks on the new rom wiping dalvik clears the previous apks stored dalvik cache. In most cases you can flash without a problem. But I recommend wiping between rom flashes just to eliminate any potential problems. Flashing something like Thriller over the stock rom you can probably get away with not wiping anything since all the apks are essentially the same. Flashing kernels you don't need to wipe anything. When flashing a rom with a completely different firmware I recommend a full data wipe. Restoring recovery backups such as nandroid require no wiping at all.
Also, wiping dalvik shouldn't affect any of your settings.

When switching ROM with different base apps, it is generally better to wipe caches than to get stuck in a boot loop, or having your apps and launcher FC on you. You never lose anything as the cache rebuilds itself on the next reboot, except maybe a few minutes

If you followed the instructions you did a full data wipe. When you do this the dalvik gets wiped as well. To just wipe dalvik look under the Advanced menu in cwm recovery.

clearing cache
i am using a nand rom in my HD2, and i also want to install another rom via SD in Magldr, but because of kernel issues i cannot load the Rom from SD unless i use the kernal i am advised to use. I am instructed to clear the dalvik and cache, but does this mean that i would lose anything from my current NAND rom? I still want to be able to use that of coarse so i just want to make sure there are no major risks when clearing cache.

Clearing dalvik and cache wont make you lose anything, used to do it with my shift because I'd flash about 10 zips a day sometimes...
Also when it comes to flashing any ROM I format system data cache wipe dalvik cache and do a factory reset just to be sure nothing from a previous ROM is left over also wipe my SD ext partition when running an a2sd ROM, my question is can I safely manually format the emmc partition of the thrill from the mounts and storage option of cwm

[Q] CM7 bootloop initial boot

Well, i am stuck at bootlooping after flashing CM7.1 onto my friend's device, we've tried many times flashing it with different ways, but it seems to get stuck everytime at the bootscreen, i know the initial boot can take up to something like half an hour but after 2,5 hours we gave up, downgraded to 2.3.4 again using odin, and tried again on a different way (different recovery)
this is how we flashed it:
-made sure we had 2.3.4
-wiped data and cache with CWM 4.0.0.idk (the odin package for this CWM was included in the thread)
-installed CM7, everything went smooth
-rebooted, and then it got stuck
I really want to get this to work for him, any help from you guys?
is it because i wiped after flashing ?

Well the process should be like this :
1. Wipe data - Wipe cache - Wipe Dalvik-cache - Wipe Battery stats
2. Flash ROM
3. Wipe data - Wipe cache - Wipe Dalvik-cache - Wipe Battery stats

So twice?
He's not here right now with the device, but i want to gather enough info for tomorrow to retry

Yeah, it is safe to wipe before and after flashing.
And you're sure you did wipe dalvik-cache right ?

errrrmm, i don't remember, i think i did tho, i will, as again, retry tomorrow with also wiping dalvik

Well, as for me, when something went wrong, i flashed my device back to stock froyo first.
Then flash GB, Flash CWM, clear data and cache, flash the rom, clear data and cache again.
Reboot.
That's it

Always explain what went wrong, if someone with the same issues is reading the thread they'll know what not to do then.
So, what went wrong before?

[Q] Endless Boot & Gapps issue

Received this phone a month ago, just got around to rooting it yesterday. Root with motochopper went fine. Unlocked the handset with motopocalypse, everything went fine. Installed latest CM10.2 nightly and everything ran fine, even restarted phone and it worked fine. I then realized I forgot to install Gapps, So i went to CWM and installed the Gapps through "install zip from sd card". Now phone will not progress past the bootloader unlocked warning screen. I can restart and put phone into recovery or fastboot no problem but I don't know where to go from here. I tried a factory reset and reinstallation of CM but to no success. I am a bit of a newb when it comes to external programs like RSD Lite and haven't used it. Is there something obvious I'm missing in my progress of trying to fix my phone?

clear cache and dalvik cache under advanced then restart.
if you still loop do the above steps plus data reinstall cm10.2.
if you still loop do all above steps but also format system under mounts be re-install.
if you loop after all that then try a different ROM.
PS what version of gapps did you use.

i can't post outside links yet but on the wiki.cyanogen site in the Gapps section I used the 10.2 20130813 1f51b5cc6370c1f45dc951109b6ce6ed release. I will attempt those steps once i can find a legitimate charger in my house. Phone doesn't accept power unless its on and i need just a bit of juice to boot it up

Here's the official name. Installed cm-10.2-2-130814-NIGHTLY-mb886.zip for the cm and gapps-jb-20130813-signed.zip for the GApps, both latest versions I believe

none of the above steps worked unfortunately. Is there a set order of certain things to be mounted and unmounted in the mount section? Such as the system or sd card?

did you flash gapps before flashing the ROM because the ROM flash will overwrite the gapps.
PS I suggest using zgapps http://forum.xda-developers.com/showthread.php?t=2240652 because they are stripped down which tends to prevent a lot of issues and if you want a 4.3 ROM try skeevydudes PAC ROM it is more stable plus has more features.

Thank you for all the help. PACROM is up and running swimmingly, all of the features are there and it is definitely better than CM by itself. Thanks again
