Wrong Directions?

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.

Went from ICS-SUPERLITE 5.0 to Stock ATT ICS, stuck at boot animation

In CWM, did the typical things
A Data/factory Reset, Format: System, Data And Cache, And Clear The Partition And Dalvik Caches, Do That To All Of Them 3 Times Each.
ran new radio zip.
Booted into download mode, and did odin thing as instructed following info here http://forum.xda-developers.com/showthread.php?t=1652398
used the md5 for latest stock ATT ICS.
This went thru fine and rebooted.
here I am, at ATT boot animation, just runs once and sits.
I can get into android system recovery....
What do I do next?
please point me if I missed the obvious thread......

factory reset in the recovery

no dice!
any other ideas?

OK I tried flashing different things, went back to CWM, then did stock again.
works!
yuck I hate this bloat ware

one of my recommendations in that post you followed was try factory reset and/or flash the stock again if things are not right, especially coming from custom roms.
but i will edit the radio flashing to do it 2 times and add another warning to reflash stock again

[Q] Help needed - stuck on CM10 boot-up animation

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!

[Q] flashing from cm11 to 12 nightly then PA bootloop help needed

ok so here is what i have done and what has happened. so far google and the search box keep taking me to threads with similar problems but those fixes dont work or do not apply to me afaik.
so i started on cm11s stock rooted on the One. (bootloader is already unlocked)
checking the PA rom thread it said if you are flashing from cm11 make sure to flash to cm12 first, then flash gapps.
once that is working get into recovery mode (twrp in my case) clear cache and dalvik then flash PA rom
done that then ended up in an android apps loading bootloop. i have flashed GAPPS also but still remaining in the bootloop.
now if i go back to cm12 i can get to the homescreen and use it a little. but once i plug the usb cable in (connected to PC) it reboots. it also reboots randomly. i have since just wiped the entire phone. now once im on the homescreen i try to access the internal storage in windows and the device appears but does not show anything. i am trying to copy the PA rom zip and Gapps zip to the phone to try flashing again. since it has been crapping itself i have been using adb sideload to flash files.
so what am i missing, what have i forgot to do along the way?
cm11 to cm12 then PA as per instructed is giving me a bootloop (with wiping cache+dalvik when supposed to)
any help is appreciated,
cheers,
kanjo

The PA thread actually says to flash PA over the top of CM12 while only wiping cache and dalvik cache? No wiping system or data? I'd put money on that being the cause of your problems. The only reason to flash CM12 first is to have the proper updated firmware installed in preparation for PA. Leaving the system and data partitions intact before flashing a different ROM (PA over CM12) is asking for trouble.
Go into TWRP and perform a full wipe (system, data, cache, dalvik cache), then flash the PA zip and the gapps zip and reboot. Don't flash CM12 again because the firmware was updated the first time you flashed it.
EDIT: Exactly which thread are you getting these instructions from? Neither of the PA threads that I'm aware of contain those instructions.

was coming back just now to update whats happening.
i finally got PA to boot. after many many fresh installs of cm12. one booted without a loop. i went back to twrp did a factory reset (wipe of dalvik and cache) (device was already freshly wiped of all data) had tried this many times but it finally booted.
now i have some weird things happening., ie. if i go into settings and enable or disable ADB the phone reboots... it didn't have that happen when i was on cm11. so not sure why it is happening now.
further if i install GAPPS i get a boot loop of android is upgrading. not sure why. the only boot that seems to work is when i run PA no gapps and no SUroot. any ideas why this is happening? or for how long the android is upgrading is meant to loop. ive seen some people say it is normal and could last 10 minutes. ive sat through multiple sessions of this some 1hour+ long. so not sure what is going wrong. i dont usually have much trouble flashing roms. this one is puzzling.
**edit**
forgot to add when it does boot. well when it did,. its now on a Android is upgrading loop after flashing GAPPS and enabling root......
anyway when it did boot the homescreen would show an error saying "settings has stopped" not sure why that is happening either.

Just to be clear, you've wiped system, data, cache, and dalvik cache directly before flashing PA? No CM flashes since wiping all of those partitions?
Also, which thread are you getting those install instructions from? Neither of the PA threads that I'm aware of contain those instructions.

ill try to clean up what has happened here;
have tried booting to twrp. wiped all data,
flashed PA
booted. with weird errors (settings has stopped and reboots on usb plugged in or adb turned off or on)
tried to flash gapps and enable root
now bootloop of android is upgrading.
going to go back to twrp. wipe all data and flash PA again without gapps and without root. will report back in about 10 minutes. will flash by using TWRP and ADB sideload.
do i need to reflash cm12 if i clear all data in twrp? i saw you mention above once i have flashed cm12 once it will have the need FW files to go to lolipop (in this case PA rom) at the moment i am trying to sideload PA rom after wiping data, system, cache and dalvik. is this why i am having the issue?
im dead tired so i admit i can be making mistakes though everything i have done seems to be what i am meant to do. flashed from cm11 to cm12, cleared all data, then flashed PA+gapps and root. = upgrading boot loop and errors mentioned above. tried flashing just PA and it booted with same errors, flashed gapps and errors.
all the files MD5s look good. not sure what is wrong.
--edit--
okay now i am at homescreen on PA.
when enabling/disabling adb in dev settings i get a reboot. is this normal now? does it need to reboot to mount the filesystem or something?
when it does boot after enabling adb i get "settings has stopped"
going to go to TWRP and flash GAPPS now and leave root not installed. will report back in a sec.

You only need to flash CM12 once, ever. The wipes don't remove the firmware.
Right now this is the exact (and only) process you need to follow:
1. Boot into TWRP.
2. Wipe system, cache, dalvik cache, and data.
3. Flash ROM + gapps together.
4. Reboot phone.

Not sure why that's happening of you're following the correct process. Maybe try with a different ROM.

balls, was hoping to us PA, haven't used it since my old s3 and figured it was the rom for me again. will have to check the rom comparison spreadsheet and look into others.
right now i have sideloaded PA alone. will copy PA and gapps to the internal storage to make things easier.
but it doesnt look like it is going to work for me.
going to try it once more like you said but locally rather than through sideload. though the internal storage is deciding when it does and doesnt want to show up.
TWRP
wipe system, cache, dalvik cache, and data.
and flash them both in tandem.
and for the fun of it when it asks if i want to install root i will let it go right ahead.
maybe this time it will work. if not then its a different rom for me. sadly.

okay so now **** got retarded. TWRP has been replaced by the stock cm11 recovery and i am too pissed off to think straight and cannot remember how to get this son of a ***** rooted again let alone to flash TWRP. i dont want to use any toolkits they all seem broken as hell.
can anyone point me in the right direction because ive just about lost my **** and this phone is going to meet my fist head on very shortly...
**edit**
done. after all this i am now on cm11 stock rooted ....seriously. hours upon hours, just to get back to where i started.
man i love when things go smoothly. anyway cheers for your help @Heisenberg . n

SM-920F stuck in bootloop when trying to restore in TWRP

1.Your bootloader status if applicable
2. Rom name with complete baseband/date/version
3. Kernel name
4. Any Mods you are using
5.If you are using Custom Rom, your flashing style i.e dirty/clean or you wiped anything else in specific
6. If you used any guide, link to the guide
7. Root status
8. Your exact problem
9. Any method you tried that failed
10.Any other detail you think would be necessary
1. Unlocked
2.Nemesis [ROM][7.0][DQB7][06/03] Link here!
3. Linux 3.10.x
4. Installed S7 edge battery. guide here!
5. Clean wiped (dalvik, cache, data, system)
6. No particular guide, just random posts through search.
7. Rooted
8. I restore a backup in TWRP and after restore, I get stuck in boot screen (Samsung logo).
9. I've tried wiping several times and restoring different backups. The only way to bypass this boot loop is to do a clean install with no restore. This means flashing everything from the beginning again. I flashed latest TWRP to 10.1.1-0 thinking it might be a issue with bad TWRP. No results.
10. This issue began when I installed S7 edge battery into S6. I would get stuck in bootloop and in TWRP cannot restore my backups so I had to clean install a rom to bypass bootloop. Today I fully discharged and recharged it to calibrate my battery and when booting got stuck in bootloop again. Still can't restore backup in TWRP, so looks like I'll have to do clean install again. Its frustrating cause it feels the slightest change will corrupt my rom and I have no choice but to reflash everything and spend hrs setting everything up. Searched for hours and still couldn't find a answer.

ROM releated issue, you cannot pass that if you don't know which files corrupt... Only you can try wipe dalvik then cache and maybe data... But I don't wish good future to working that XD
