If you went and wiped cache only, not data, and installed a new rom, would all data remain? What exactly is this cache that nandroid wipes?
I'd like to install a rom for a friend but dont want to completley wipe his phone. I just want to install the virtuous rom, which is basically the stock 2.2 update rom and would like to keep all his data on the phone. would just wiping the cache work? I know some people just install without wiping but would wiping cache help?
And I know a wipe is always better, thats what I do on my phone. But its not mine and would like to save his data.
I am trying to install [ROM] Uncommon Sense (v1.0) Release! - xda-developers and it says I need the full wipe! Does that mean I have to wipe? the cache and data? The two options availabe for wipe in the menu? Also, I place the zip in the root of the memory card, yes?
my verizon galaxy tab 7 (sch-1800) doesn't boot, it freezes on samsung splash. I already restored the stock rom, but it doesn't change anything. if i try to restore default with recovery mode, it says E:failed to mount cache.
Screen mirroring broke on my note 2 with the 4.3 update.
I've read one possible fix was to clear the cache partition (?) But have no idea on a non rooted phone how you would accomplish this. The other alternative is a factory reset but I would need to figure out how to back up my accounts/data to do that.
I was flashing CM9 from CM7 on my Motorola Defy, botched it up intially due to a slip of my finger which led to me to Clear the cache first. But then I restarted the entire process by Clearing Data -> Installing -> Flashing Kernel and so on...
But when I tried to clear the Dalvik Cache, the phone didn't delete it. It didn't give me a message that it wiped the cache, but it didn't say otherwise either. This led me to believe that the cache just didn't exist anymore.
As a result, I'm unable to install apps - Says there is no memory and I need to make more. Also, everytime the phone comes on is treated as the first time. It takes me through the whole process of Setting up an account and everything. This has rendered my phone obsolete.
I was just flashing a new ROM for my gio, and made sure that i did a factory reset, wiped cache partition and wipe dalvik cache. but when i went to wipe the dalvik, CWM froze for a bit, then showed the yes/no part for like half a second, then kicked me back to the main menu. It does this every time. What to do? or should i just reflash it?
I changed my default font system and after reboot my phone freezes on boot animation and doesn't boot to system. i have a backup from all my data and rom. If i had to flash what should i do before?should i wipe cache, dalvik cach, factory reset and system? and then install zip?
I have an HTC ONE, and a Samsung Galaxy S4 that I am trying to sell. I know that it's fairly easy to recover data from a wiped partition by using programs like "TenorShare Android Data Recovery", unless data has been written over them at least once.
I had taken pictures of some documents containing highly sensitive data with the phone, and would like to make sure that those documents are not recoverable by the next user.
Neither of them have the USB Mass Storage option in the settings, so I can't just use some secure wipe program.
Wanted to wipe data/cache before i flashed a new rom..so i did it in recovery..but after i did it and rebooted, when i got to the "touch android to begin" the touch wouldnt register..what's the problem? tired it a few times and was the same.
I'm considering installing a rom and I've heard that doing a data and cache wipe is the proper thing to do to ensure success. What I'm concerned about is how easy it is to restore/re-do all of your settings like ringtones, notification settings, app settings etc. How long does it usually take you to set up your phone again after installing the new rom?
If you do not root, you could go from 2.0.1 to 2.1 with no wiping of data and cache, it just installs & away you go. Same with 2.1 to 2.2. No wiping of data and cache and all is still there as you left it: apps, settings, preferences, etc. SO, why is it important to do this if you root? What's the difference? And, who said it was important to do? Is there some exact proven logic on why if your rooted you must do this and if not, your somehow fine? That 1 step difference causes a lot of extra work, so I am wondering why this is said to be a must for rooters and non rooters need not do it when they get updates?
Im running CyanogenMod 18.104.22.168 with BlackIceTheme right now and im wanting to switch to NexTheme 2.0 so just switching themes not roms i went ahead and downloaded it on rom manager and installed it without wiping data/cache when the phone rebooted it had no signal and still had part of the BlackIce theme and parts of nextheme so no i need to wipe data/cache before installing this theme
I am confused about the whole wiping the cache and data. I don't know exactly what cache and data are and that's why I'm confused. Do u have to wipe all data and cache before u switch Roms, if not what happens? I am afraid of losing all of my apps and contacts even tho my gmail will restore my contacts how do I know if it has the contacts saved and how would I get my apps back? One more thing, do u have to make more than one backup if u already have one that u r happy with?
When downloading a custom rom and the dev says wipe data/cache thats when im in recovery right? I see the options but do i do the data first and will it take me out of there and I gotta go back then wipe the cache? or will it just wipe data and then hit the back button and wipe cache and then hit the back button and hit install from sd?
I have installed UD8 for about a week now. But ever since I have flashed some kernels (slayers 1100lv, chevys 1100 lv, p31200) I have not had the stability nor the quickness that the original 800 stock kernel gave.
I made a nandroid backup b4 flashing those roms..so my question is this: Do i have to wipe cache/data before i flash my nandroid backup? Or can i just flash it w/o doing any extra steps?
OK, before I start, it's about an LT15i. I don't know what's happening, but at some .FTFs Flashtool does not show the file list (middle column) and neither "wipe cache" or data and one FTF has the "wipe cache" option only. This is really annoying. Tutorials specify a download link for a specific FTF and after starting Flashtool and selecting the flash option, that FTF is not showing up properly. Should I download an earlier version of the program?
I am running rooted stock Android 2.3 on LG E405 (no working 4.x ROMs exist for the device)
I have two questions:
1) What is the shell command to manually make android allow the PC to mount androids' (internal) partition as USB-drive? (I cannot think of right keywords to google this one up - )
2) How does android determine which partition is which (i.e. which one to remount for the PC when connecting in "USB storage" mode), beside vold.fstab and init.rc? On android 2.3 that info is not in "framework-res.apk", so where is it? In the partition table itself?
I had switched data partition with internal sdcard partition.
Here's how: Phone had a very small "/data" partition on /dev/block/mmcblk0p21 and large internal "/sdcard" partition on mmcblk0p20
So I reformatted mmcblk0p20 (ex-sdcard partition) into EXT4 and mmcblk0p21 (ex-data partition) into FAT32
Then I changed init.rc to mount mmcblk0p20 as /data type EXT4 and mmcblk0p21 as /sdcard type VFAT (mounting /sdcard was commented out in stock init.rc for some reason). This required modifying my boot image.
I have also set correct partition number in vold.fstab:
[#]dev_mount sdcard /mnt/sdcard auto /devices/platform/msm_sdcc.3/mmc_host[/#]
So basicly I now have a large /data partition and small internal /sdcard. I'm able install up to a gigabyte of APKs and it works fine.
However, when I connect to my PC via USB into "USB Storage" mode, the phone seems to still try to unmount what was previously sdcard partition (/dev/block/mmcblk0p20), instead of what is NOW an sdcard partition (/dev/block/mmcblk0p21) I can still send files to the phone via wi-fi and ADB, but the ability to mount it directly would be nice.
If I accidentally select "erase internal sdcard" from storage menu, that will also most likely erase what is now my /data partition, softbricking the phone. The "factory reset" option will probably only corrupt the sdcard.
I'm have been trying to create a second partition on my sd card using miniTool Partition Wizard.But in the end I never get a 2nd partition but just a smaller first one.My approach is as follows:
insert empty SD card (FAT32, 4GB) open miniTool Partition Wizard right click on SD card - "Move/Resize" choose 1gb for unallocated space after - click ok right click on 2nd partition and choose "create" create 2nd partition with FAT32/Ext2/Ext3 (tried all options already) and "primary" and Cluster 4KB - click ok Apply
Afterwards my SD card is still shown as one partition, but this has just 1gb less capacity then before.Neither the Wizard nor the phone detects the 2nd partition then.
I have bought a cheap chinese phone that had a 4g rom. 512mb is mapped to data as p3 and p4 is mapped to internal storage which is 2g.
I have managed to work out how to delete partition4 and extend partition3 as they follow on from each other. However how do I remove all links to it in the system as it still tries to mount it on boot even though it isn't there.
I have removed the line from vold.fstab and that just crashed the external and internal sdcards and the storage section inside the system settings.
In cm roms, dalvik cache of system apps are generated in /cache but those data/apps are generated in /data. Is there any way to disable this behaviour? Cache partition in our phones is too small. In AOSP and AOKP and stock roms, dalvik cache is always generated in /data no matter whether its a system app. any way to achieve this in cm roms?
