My phone was building up too much cache so I decided to go on TWRP and do a wipe of cache and dalvik cache, but after that it started to lag *a lot*. After booting the phone takes a lot of time to load the launcher, Google feed works after 5 minutes of the boot, everything lags, it doesn't detect the Sim card unless I pull it out and in again. What did I do wrong? I what cache is and why does it exist but I didn't think this would do so much harm.
Should I reflash the ROM or something like that? Don't know what to do.
I thought after a few boots it would build up enough cache again to work properly but it has been a week already and every boot is the same, it takes at least 10 or 15 minutes to work properly

Are you sure you haven't wiped any other partition?
Are you on stock ROM?
Anything installed to cache like the loopback bug fix for magisk?
Usually the wipe of cache and dalvik causes no problems, the first boot will take longer but after that everything should turn back to normal again.
If the problems persist a factory reset or if that doesn't help a reflash of the ROM may solve the issues.

I decided to flash the ROM again, I am on the Pixel Experience rom, didn't have any fix or anything like that, but after reflashing it has been working better, guess I'll wipe dalvik only when flashing something like a Magisk module.

I haven't wiped dalvik/cache for over a year now while flashing magisk, different modules and other stuff. I personally think wiping cache and dalvik is overrated on newer devices.

I'll surely not do it again because it ruins the launcher an awful lot.

Hey, first time posting. Flashed Shooter RLS 4.4 (first ROM) and everything was GREAT. I decided to change the unlock Screen from Android to Honeycomb (because it didn't show who was calling if the phone wasn't unlocked) and it said that I needed to reboot. So I did... And then it's been stuck on the white HTC Evo 4G screen ever since. I took out the battery and tried restarting, nothing. I took out the battery, booted into recovery, attempted to reboot via Amon Ra,...back to the white screen. Anything I can do other than re-flash the ROM? I don't have a nandroid backup (yeah, messed up).
Thanks in advance for the help.
Did you try wiping the Cache and the Dalvik while you were in recovery?

Just did and so far it's back up and running. A lil sluggish right now but I'm sure it'll work itself out.
Appreciate the help.
What exactly does wiping Cache and Dalvik do, if you don't mind explaining.
Thanks either way.
You need to wipe everything before flashing a new rom and cache and dalvik before flashing a theme or mod to a rom, cache and dalvike are temp files that need to be erased and rebuilt, you have to wipe everything else when flashing a new rom to get rid of all the data just like formatting a hard drive before installing a new OS

Since installing CM10, my N7 shuts down/crashes overnight on charge. and after rebooting, still on the charger, it will shutdown again usually. Any ideas what this may be? Never did it on stock. Is there a CM forum to report this?

How did you flash to cm10. I would re download the latest cm 10.. (these change very often ). Do a Full wipe dalvik cache System and so on.. Then Flash the fresh copy.. CAUTION: if YOU WIPE DATA. You will have to adb push cm 10 back to device while in recovery/boot-loader..
Reflash after the full wipe.. Boot back into recovery after flash before first boot wipe dalvik/ cache . then see how it does.. Could be just a bad flash.. Or nothing more then a bug on that nightly of cm 10..
Your request for help is very vague on what and how you flashed. The more info you give the better answers you can receive .....

I will try that. I thought I did a complete wipe, but I may have flashed over another rom. Sorry for the sparse detail, I was seeing if this was a known issue or likely just a possible problem in my install. I'm using twrp recovery, if I wipe data, I can flash from otg-usb mounted flash drive.
Thanks!

Yes you can but make Sure before you wipe data that you can see the otg drive Sometimes from in recovery twrp you need to select reboot reboot recovery.. for it to show up.. not sure if its my drive or what...
Good Luck.

Wiped everything, I did have to do the reboot recovery thing to see the USB, but all went well after that. Seems to have fixed it, it woke fine this morning. Not mush loaded, so if it was an app, I'll find out as I load them back slowly.
Thanks.

Well, I flashed 1130 nightly over 1129 nightly, and it did it again. This is frustrating, What are the correct steps for flashing a nightly?

Hi,
Coming from PureNexus, I wanted to give CM13 a try. Made a nandroid backup so none of my data is lost, and put that backup on pc. I installed CM13 which went fine. It stopped at the CM booting animation and did not go further, so I cleanflashed Purenexus to restore my backup later on. Now PureNexus won't boot either. I'm out of ideas to try, and I want to get my phone back up and running ASAP.
Can anyone help me with this issue?

When you clean flashed, did you also wipe system? If you did and you're still hung at boot, your best bet would be to flash the factory images via fastboot and start fresh.

Are you wiping properly (system, data, cache, dalvik cache) before installing a ROM? Are you making sure you flash the appropriate vendor image after flashing the ROM? When you made your backup which options did you check? And which options are you restoring?

When I try to wipe, it's only wiping cache for some reason. My backup consists of everything except cache.

What do you mean it's only wiping cache? Explain to me how you're doing the wipe. Also, when creating a backup (and restoring it) you should only be selecting system, data, boot, and vendor.
PS. You didn't answer my question about whether you're flashing the vendor after flashing the ROM. If you want help you need to answer the questions that are asked.

I'll keep that in mind. When I boot up TRWP, I wiped system, dalvik, data, internal storage and cache. After that I pushed CM13 through adb. That's where the problems started.
EDIT: I flashed the most recent vendor after I flashed the ROM.

Ok, you definitely don't need to wipe internal storage before flashing so don't worry about that part. Only system, data, cache, and dalvik cache. You said before only cache was being wiped, can you please elaborate on that?
Are you sure the ROM zip didn't become corrupt during the download? Did you check the MD5 to ensure that it didn't? That could be what's causing your problems. Also, what gapps are you flashing?
If you want to go back to Pure Nexus just to get your phone working you can just restore that backup, just make sure you only restore system, data, boot, and vendor.

It won't wipe anything other than cache, no matter what I'm trying to do. Now when I'm trying to push a ROM through adb, I can install it but it won't boot.

I found your guide by googling, thanks for making that! Flashing the factory image worked, and I succesfully restored my backup. The only problem left is that it won't accept my pattern lock. I have used the same one for years across multiple android devices, so I'm absolutely sure I have the right pattern. Any way to bypass this?

You need to remove all security before making a backup because the security information is encrypted and doesn't get backed up or restored properly. You can delete some files using TWRP (see section 3 of my guide) in order to remove the security so you can get into Android. This will cause problems with Smart Lock though.

I installed Naptime (rooted phone). Put my 6P into standby. Worked for 15 minutes. I went away and came back and the device was in a bootloop. Can't believe naptime could be the cause of this, but things were fine before this was installed. Symptoms sounds like the bootloop others are complaining about.
Wiped the Davlik cache. Made no difference.
Tried to restore my TWRP backup and that reboots after about 90MB. If I choose verify the MD5 backup, TWRP reboots after about 30 seconds of verification. So it seems like any I/O attempt on the system partition is causing the 6P to reboot. Is there anything else I can try before resorting to an RMA w/Google?

Wipe everything except internal, and not only the cashes, and try your restore again.
You can also try to install a full factory image from the Google website using flash-all.bat command.

Tried a full factory install of 7.1.2 (was on 7.1.1). Didn't help. Shows the Google boot logo and then reboots.
What is interesting is fastboot was able to write the system image for 7.1.2.

I'm on TWRP 3.1. Just noticed its crashing wiping any of the items (cache, Dalvik cache etc.). The reboot happens after it shows updating partition table.
Was finally able to get a clean Dalvik cache wipe. I noticed that in all cases, there are three TWRP errors about mounting the cache partition before it does the wipe. Is this normal?

I don't know if it's normal but I've seen the same errors on my device after installing the 7.1.2 factory images and wiping the cache in TWRP 3.1. I assumed it might have to do with no cache partition being included with 7.1.2.

What does your reboot loop look like? I see the Google logo for a few seconds then the device reboots. I never see the animation start.
H'ola,
so i'm running MIUI 11.2 latest beta from xiaomi.eu on my 9T , rooted with twrp. i like to "reset" the phone, just soft-reset .. deleting everything, a complete wipe.
When i'm using the miui option for it, the phone going to restart into twrp and then nothing happens?
maybe someone of u know, how to do it?
thanks
From TWRP, format data, wipe cache and reboot.
thanks, i was a bit unsure about that .. coz i read a couple of times "never wipe system,data partition on a 9t" ..

I confirm that you should never wipe system or vendor on the 9T, even prior to flashing new ROMs. Doing so causes soft "stuck in fastboot" bricks on many Xiaomi devices.
Wiping or formatting data is totally fine (well assuming you want to lose your data). Formatting data is required after flashing a different ROM or if you want a true Factory Reset.
I just wiped data and cache, it worked.
Thanks
