[Q] Question about nandroid backups location

Hi, I've got a Nexus 10 and I already have rooted and installed TWRP recovery. I'm used to get devices with microsd slot. As this is not the case, I have a noob question.
I'm having problems installing certain apps and I want to try wiping the device and see if after wiping, the installation suceeds. Just in case, I have already taken a nandroid backup, but, as the backup is located in the internal SD, I'm afraid that if I wipe the device, it will also wipe the backup. Will wiping the device erase the TWRP backup too?. The backup is located at /sdcard/TWRP/BACKUPS/...... and so on. I think that wiping the device shouldn't wipe the /sdcard partition, but I'm not sure about this.
Can you please confirm that wiping the device will erase only /data and not /sdcard?
Thanks a lot.

I can't confirm anything; but I'd highly suggest just backing up the nandroid to a computer just in-case. I'm pretty sure though that the nandroid would remain as long as you didn't actually format data.

That's what I've done so far. I have copied the nandroid backup to my PC. I suppose that it's possible, in case the backup is deleted, that I can mount the partition from recovery and then using adb, push the backup in order to restore it. Is this the way to go?.
By the way, what you mean is that the backup will remain as long as I don't format /sdcard, right? Because /data will get formated if I wipe the device, I think.
Thanks.

Not entirely sure; I know in TWRP there's some advanced wipe thing with selections (cache, dalvik, system, something else, usb) and then there's a "Format Data" button.
wiping cache, dalvik, system, and factory reset it will not wipe your "media" partition, also known as your sdcard or internal storage. Doing the "format data" will wipe the whole device including your sdcard.

I finally wiped the device, tested the application I wanted to install and recovered without problems from the TWRP backup that hadn't been deleted. Now that I know that wiping the device solves the problem, I have to backup apps and data for every user, wipe again and recover only apps and data.
Thanks a lot.

[Q] Change rom using TWRP recovery

Hi, I'm on PA 3.99 rom and I'd like to install Purity Rom, but it's required a full wipe. My recovery is TWRP, so for a full wipe I need to wipe cache, dalvink cache, system and factory, right? Internal and External card isn't necessary, right? Because It will erase the Purity zip in my memory and I won't be able to installed. If possible I'd like a clear response, so I'd finally understand what to do exactly with no more worries.

That's correct, cache, dalvik cache, data and system. Your external sd and internal sd should be untouched.

A factory reset in recovery wipes /cache and /data ... the dalvik cache resides on the data partition and is thusly wiped also.
You could wipe /system to be "thorough" ... but the Rom zip.should have a format /system line in the updater script.
I only ever do a factory reset between roms.
Thank you very much, it's what I wanted to hear! (Never understood if wipe factory was even wipe data ahah XD)

Meizu MX4 bricked - can't mount cache

I tried format cache on twrp-3.0.0.0 and now I can't mount cache partition. System wont boot and reinstallation does not help. I flashed old 2.8.7 recovery and new 3.0.0.1 but nothing helps. I wont only reinstall Flyme.
Sorry for my bad English.
I wiped successfully my cache partition with this recovery.

CWM-Philz Touch Recovery stuck freezes on wipe/format every time [Philz6.0.4.8]

Is there a known bug with philz and wiping partitions? I cant wipe the cache partition or any partition, The screen continues to load but makes no progress. When I turn off and reset the phone, the cache cant be mounted again due to 'last logs' missing. So If I flash back to TWRP, the cache partition is empty 0mb instead of the usual 4mb residual. Re-formatting fixes the issue but it renders CWM-Philz a little useless when you cant even wipe the cache without issues.
Does anyone know a workaround for this?​
Move to TWRP as a custom recovery. CWM/Philz has not been updated for a long time.
