I know this is not a development thread but I must insist we have something like this in this area. I feel it's important to all development for accurate results and debug information.
I see this all the time. People think they are fully wiping when a developer asks for it. I believe that some people still don't understand what a full wipe is because there is no such single option in ClockWorkMod Recovery. Most likely the reason for that is because Koush didn't want too many posts about "I'm stuck on Google logo" or "my phone won't boot". So here is a test you can do yourself: Backup your ROM of course, and then do a full wipe. Then don't install anything and just reboot. If you end up pass the Google logo and onto the boot loop screen, then what you think is a full wipe is incorrect. If you are stuck on the Google logo and nothing is happening however, then congratulations... you know what you're doing 
For the rest of you, here are proper steps to fully wipe without leaving any trace of ROM on your phone:
* wipe data/factory reset
* format /system
* format /boot
Now most people think that the first option is enough. That may often be the case but because the developer can drastically change the contents of the /system folder, things can get messed up if you don't format it. And guess what, that first option will not do it. Wipe data/factory reset only wipes the /data folder which contains your personal settings and all the apps you installed. The ROM is then left blank as if you just flashed it and you can start over. FYI, the format of boot partition simply wipes the boot animation and you can restore it using the advance option in recovery from ROM to another.
I've seen some zip files which do this automatically so that's fine but at least you know what needs to be done to fully wipe.
There you go. I hope this clears some things. Now lets flash some ROMs!

i cant get rid of the boot logo.. tried it hundred times, but the problem remains.. after flashing any rom, i first get the canvas logo, and then the rom boot animation starts,,, and cant even see the "format\boot" option.. is there a problem with the CWM recovery or my device?? CWM recovery is "CWM-based Recovery v6.0.1.2" (compiled by Bruno Martins)

You can't exactly Wipe or remove the boot logo, but you have to Overwrite it! So just choose the boot logo you want and then download it and flash the zip file! Here is the Stock Boot logo.
thanx buddy this guide really helps me

I'm all ready to flash a custom rom on my device and came across this: How To Load Custom ROM on Your Android Device (After Using the Revolutionary Method), ( <---- type this link into google apparently im not allowed to post outside links so just type it in to google) however no where in the instructions is he wiping the cache partition or dalvik cache, I've heard from most people if you don't wipe the cache you could end up with a phone eating a bowl of boot loops, or having a paperweight, so is he wrong or is it not important, please explain?
Yes it is very important when flashing a rom or flashing just about anything else to wipe cache and delvik cache. Also if flashing a rom for the first time you must delete all data/factory reset. Wiping the caches will never hurt anything it will just make your phone take a while to boot the first time so don't be afraid to do it when flashing anything
Sent from my SGH-I777 using xda app-developers app
It is important as the last person explained. Though check your phone model and see if it has a hidden recovery or boot loader. Phones like my triumph let me get my phone back even it gets stuck in a boot loop or corrupts the recovery menu.
Oh okay thank you both, its just I have an htc aria, and I want to flash a rom, but I don't know how, I have it rooted, but i don't know how to flash a rom successfully, because I don't want to brick it.
Hi All,
I have the Telstra HTC One XL, and have just recently attempted to install CM10 ROM - however have run into some problems that I would appreciate some advice to rectify. I had recently updated to Jelly Bean OTA.
I followed the guide on these forums - http://forum.xda-developers.com/showthread.php?t=1859478
I Successfully unlocked bootloader by following the steps at HTCdev.com
I Successfully installed TWRP Custom Recovery
I Downloaded CM10 as per - http://forum.xda-developers.com/showthread.php?t=1790032. I transferred this as well as Google Apps onto my phones storage.
When attempting to install CM10, I created the Nandroid backup as recommended, and proceeded to wipe the mentioned items using TWRP (a guide I saw said to wipe everything). This is when my Nandroid back-up got wiped. TWRP gives you the option to wipe cache, delvik cache, factory reset, system, external storage, internal storage and format data. I did alll of these, and this was my mistake I believe? I proceeded to try and install CM10 and gapps from internal storage (I had to re load these back on after I wiped everything), and the install of CM10 displayed as successful.
Upon rebooting to system, the HTC screen comes up first and then goes to the CM10 animation. The phone then stays on this animation (rotating circle) for up to 10-15 minutes.
I have read thread after thread with people experiencing similar issues, and have tried rectifying my problem with various versions of roms and different guides out there. I can still boot into recovery (TWRP) mode via bootloader, and this means I can still mount my phone's storage onto my PC and have access to the storage directory. As I have deleted the Nandroid backup though, and because the ROM's won't install, I am stuck in no man's land.
There must surely be a way to have a ROM installed (even if its back to stock Telstra) from the position I am in, it would be greatly appreciated if someone may be able to point me in the right direction.
Thanks,
Robbie
maybe yall need to "fastboot flash boot boot.img" now

Why do people keep doing this??? Just because TWRP gives you all those options, doesn't mean you should use them.
Sometimes, people will say to do a "full wipe" when flashing a ROM. But that term is a bit misleading. Factory reset (from TWRP, never from hboot), wipe Dalvik and wipe cache is all that is technically required when flashing a new ROM. Some people like to wipe more "just in case". But if you aren't completely confidant in what you are doing, keep in simple and don't make it more complicated than it needs to be.
I don't know if wiping everything is the cause of your woes, but it certainly didn't help, and caused you to do some extra steps.
Flash boot.img via fastboot as previously suggested. Otherwise, just try to re-download and flash the files agin. Its seems that some people are having troubles booting after flashing CM10 (even after doing the correct wipes and flashing boot.img). Doesn't seem to be much rhyme or reason, but just flashing again has fixed the problem for at least one person.
Thanks so much, such a simple fix! That has me booted up into CM10.
I have installed cm-10-20130107-NIGHTLY-evita and cm-10.0.0-evita , however with both of these versions, my touch screen is not working once it boots up. I can function with the volume up/down, and with the power buttons, but cannot get past my SIM card lock screen.
I noticed this thread http://forum.xda-developers.com/showthread.php?t=2083314 (no solution yet)...
Does anyone have a solution to this issue that seems a common one?
Alternatively, more than happy to get an alternative ROM on my phone in the interim...Can someone recommend me a ROM?
Again, I really appreciate the quick response to my problem, very happy my phone is in operation!
I am a relatively new android user but do enjoy flashing roms, kernels etc
My problems began when i was trying to flash a new rom on my Nexus 5
I was trying to flash this rom http://forum.xda-developers.com/showthread.php?t=2655722 but despite doing a factory reset and wiping the dalvik cache and cache it refused to boot in to the new rom
I tried to flash the rom multiple times but without success, eventually when trying to boot into recovery to try again i was greeted with an unthemed TWRP recovery asking for a password despite the fact that i had a custom theme and multirom installed I tried to proceed anyways but was greeted with E: unable to mount storage
In desperation i tried to solve this problem and found this
UsoftTech :: WwW.UsoftTech.CoM ::
TWRP asking for password
After unboxing my Nexus 5, here's what I did:
1. Booted into bootloader
2. fastboot oem unlock
3. Flashed TWRP v2.6.3.0
4. Booted to recovery
The screen that greeted me says "Please Enter Your Password".
I can hit the cancel button below this which takes me to the normal TWRP screen. I then pushed SuperSU to /sdcard, but when I flash it it fails because it's unable to mount /cache or storage.
When I reboot to the system, it takes an awfully long time (approximately 30s) to progress past the "Google" screen, and then it just seems to sit on the booting animation forever.
Any help?
EDIT: Solved my own problem.
Hit cancel at the password screen, then go into Wipe and then do a factory reset by swiping. Then go back into Wipe and press the 'Format data' button. You have to type 'Yes', and it will take a few seconds. After that everything should work normally.

I now fear that i maybe without both a rom and all my files such as my music that was stored on my phone.
Is there any way for me to undo the damage i may have done to to my phone?
You can't recover the data. But you can push files over with ADB.

About two weeks ago just before CyanogenMod's announcement of its closure I updated my Moto G2015 (1GB) to the latest nightly, which was CM14.1 released on the 25th of December, with its corresponding GAPPS version also released on the 25th of December (ARM, android 7.1, Full)
Yesterday the 7th of January my Google Apps decided that they didn't want to open, at first I thought it was just updating and since my battery was low I plugged in my device, I later realised that my device randomly went to a boot loop and stayed there. I grew impatient so I restarted the phone and went to the Recovery Mode (To Re-Flash the ROM), but to my annoyance the recovery (TWRP) just stayed on the 'Teamwin' logo forever, it would randomly go black then return to that logo. infuriated I turned on my phone and went to backup/reset and clicked 'factory reset'. it annoyingly booted me into recovery to reset the device, which of course I couldn't do.
Now the simple answer would have been for me to go and wipe the cache and data from 'google play services' and or 'launcher3' but I did, either it always shows 'calculating' preventing me from clicking 'manage space' or clearing 'cache' or when it did finally show, after I did click the button for the cache and or data to be cleared it would say 'calculating', and a quick check would discover that nothing was actually cleared.
Kind Regards, and Thank You to any help recieved,

Boot TWRP or CWM Recovery (not sure if it's still called CWM Recovery now that LineageOS has replaced it) with the command 'fastboot boot recovery.img' but replace recovery.img with your actual recovery image filename. If TWRP won't boot wait, sometimes a theme or corruption in the TWRP directory on internal storage can pause the startup of TWRP by several minutes, if that still fails boot CWMR and remove the TWRP directory or wipe internal storage.
Once you can get TWRP to boot properly, backup everything (MPT works in TWRP) and wipe and reflash, should be good to go.

Thanks for the reply, what you're saying makes sense and would probably work, but I found a simpler work around. I'm actually annoyed I didn't do it earlier.
So simply put, I downloaded my stock recovery which worked and then I just factory reset my device from there, that reset the CM14.1 ROM and let my Google Apps work again. Now about the recovery, I'm a bit skeptical about Re Flashing it, but I think I'll try it next weekend and post the results.

Have you tried it since you wiped? It might just work now that the reset wiped internal storage...

Right, so I reinstalled and flashed the latest version TWRP, when I opened into it, it took about 1 minute before it opened up, it ran a quick operation that I just glimpsed, it looked like it was wiping cache and user data, my phone was rebooted and I was right, my phone had been reset for the second time today (I'm almost a pro at reinstalling all my apps). I rebooted into the recovery and Look and Behold, it was working.
Thanks slot for your help and time.
Hello, I was using my phone normally and then I decided to turn it off because I was having a bug with an application, then I turned it on but in that process I accidentaly push one of the volume bottons and end up on what it seems a boot menu, I went for the english option and then to "exit" and "power off" so I can exit this boot menu, but it comes back again to this menu over and over I don't know why,.
I go to boot reason and appears this: fs_mgr_mount_all
Unable to parse kernel log.
I need help, don't know why I can't exit this menu because I entered by mistake and did nothing else than trying to exit. I have never root my phone or anything related to that, please help me to not lose my data!

Maybe this help you

Ok just done that but it is still stuck on boot, maybe there is another solution to this problem?
Hmm looks like your 8T is caught in bootloop. As far as i know there is only to try in Recovery the Wipe All step which deleted all on your Phone. If that also not works then MSN Tool which has the same result as the Wipe All, the only differnce is that MSN Tool sets up your Partitions fresh and complete clean.
But i can be wrong with that what i Knowing, maybe a more smarter guy can help you out with your problem.
If your phone bootloader not unlocked, the only way i know is fastboot flash .img file from official full update.zip
If that not work, wipe or MSM, but they all causing data loss.
