I would suggest booting to boot loader. Then....
Fastboot format cache
Fastboot format user data
Fastboot reboot
Note that this will wipe your SDcard and data.

Htc Eris stuck in andoid screen

can some one please help me, i root my htc eris and i install a rom but now the phone wont turn on, is stuck in the android screen.
i allready did a master reset, by holding VOL DOWN + SEND + END
I also can get in to recovery mode and i did a wipe date/factory reset, but is not working.
and when i try to do a RESTORE is telling me that there is no sd-ext.img
and no android_secure.img
can some one PLEASE help me. THANKSSSSsss........
In your recovery are you able to flash images? If so I suggest you download a ROM and try to flash it. That usually solves my problems.
Yea try reflashing a ROM, deleting everything off your sdcard, wiping factory data, davlik cache, and sd ext partition.
Wipe anything you can pretty much ha.
You should only really have to flash the ROM. I can't imagine how replacing the ROM wouldn't totally fix everything. Do a wipe first.
Also understand that it can easily take 5 to 10 minutes to boot for the first time after flashing a new rom let it sit for 20 then worry.
As long as you can hit recovery you haven't ****ed it up too bad though, that's a positive.
Nice i just run the RUU and now my phone wont turn on at all

Q- Hanging on Cyanogdenmod Splash Screen after flash?

I have just flashed my Galaxy 5 with Cyanogenmod latest and it is now stuck on a reapeating splash screen of a little blue droid guy, its not doing nothing i cant access my phone as it wont advance from this splash screen, i have removed my battery but nothing has worked.
Any quick tips/fix please?
have you wiped data, cache, and dalvik cache?
I havent a clue what you mean so i'm guessing not aha:/
whats your custom recovery?
for amonra, there should be an option called wipe and it has everything i just said.
for clockworkmod, theres wipe data/factory reset, wipe cache partition, and under advanced, theres wipe dalvik cache
I am not 100% positive but i used Clockworkmod v4 in order to get Cyanogenmod 7 onto my device if that answers your question? (im new to all this stuff).
All ive did is;
Installed clockworkmod v4
rebooted my device.
installed cyanogenmod as a zip from my sd card
rebooted my device.
Turned it back on and just this splash screen repeating
Im sorry i suck at this aha
with your phone off, hold home+vol down+power.
when it boots into clockworkmod, on the first menu, there should be an option to wipe data/factory reset and another one to wipe cache. do both.
then after you are done with that, go into the advanced menu and select wipe dalvik cache. now reboot
When i hold that combination down it brings up Download mode for some reason :S
oh yeah. my bad i was thinking about my phone.
try reinstalling the recovery (using odin) and see if it boots back into recovery (do this at your own risk; since i dont have a phone that uses odin, im not sure if this will work or not)
Could this damage/brick my phone?
Thank you so so so so much sir! Id take my hat off for you, if i wore one!
I love you.
im guessing it worked, right?
no problem
Yes ahah, longest 3 minutes in my life though! Thanks alot.

Did you wipe the dalvik cache? If you didn't, go into recovery, then click advanced, then click wipe dalvik cache.
i whipped dalvik cache, still sits in the boot logo

Maybe you've had a bad install. Try wiping everything again, and then re-installing. After you've reinstalled, wipe everything again just for good measure.
This happened to me before, just download CM7 again onto your sd card and then go into your recovery menu and wipe dalvik, wipe cache, wipe data, then try reflashing the new CM7 zip you have on your sd card and reboot

I think this maybe my problem
http://forum.xda-developers.com/showthread.php?t=1219956
cause I can only access my internal memory, but I have a bigger problem it says my battery is to low to flash and it doesnt seem to be charging. Iis there any mode under those options when you hold power and down volume that would charge the phone?
Try the method I posted on that thread to charge your phone, its a video on youtube that tells you how to.

Moving to Q&A
It's "normal" that you get a bootloop, pull the battery out, try to reboot phone again if it ends in a bootloop again, wait until led blinks blue and press vol down to go to custom recovery and wipe cache an dalvik. Then try to reboot again.
If you didn't make a clean install, best thing to do is wipe data, cache and dalvik, reflash the rom you want and try to boot again
OK

[Q] Bootloop on any rom, after wiping cache, data, etc.

Hi,
Last night my I9300 decided to randomly reboot and get stuck in a bootloop. This morning I took the time to wipe my cache, data, etc. through CWM but it still would not boot. I did a wipe data/factory reset, wiped cache again and installed the latest AOKP nightly, but it still will not boot.
I can start the bootloader through CWM and I can also get into download mode, but it just won't boot Android.
ADB does list my device while in the bootloop, but I get a "device unauthorized" message.
I've had bootloops before and wiping cache/data/factory reset/installing a new rom always worked, but in this case I am clueless.
What can I do? Is there maybe a way to connect logcat without unauthorizing, or authorizing from CWM, or something?
Do you have the newest CWM?? Or try any other custom recovery
As above, use the latest recovery then manually format system, data, cache preload and data/media/0

How can I do this if I cannot authorize a ADB connection?
If yours recovery works flash the newest version
If not flash a stock ROM via Odin
dalvik cache

On Cwm click advance and try wiping dalvik cache if that doesn't work install your stock rom
