[Q] do you need to wipe sd-ext? - EVO 4G Q&A, Help & Troubleshooting

is it necessary to wipe sd-ext between rom flashes? realistically isn't it just a bunch of apps on sd, so wouldn't leaving them on there have the same effect as just restoring them with titanium?
just partitioned my sd to take advantage of the apps2sd built into miui so im brand new to this. also i didn't find anything useful by googleing this so any help is appreciated.

Its always best to wipe it, if you're partitioned.

I've attempted do this for the same reasons with mixed results. When I did it my data was set to be stored internally though. I've wondered how it would work if data was on ext partition. U might be able to do a2sd reinstall and have em restored with data.

I does seem like there would be a way to make it work....it certainly would be a hell of a lot easier than wiping and restoring with titanium.

sd card partition?

so, i put a partition on my sd card for the specific purpose of apps2sd. I went from cm6 to slidemeroot5r1. how do I access the apps that i had saved on my sd card? they don't show up on the phone after i flashed the new rom.
I'm probably overlooking something simple, but any help would be appreciated
Umm, you can't. At least I don't think so since your phone can't see that partition unless you tell it to. I would just restore from a nandroid backup and use titanium backup to backup the apps then when you install the rom you want just restore the apps with titanium.

Assuming you wiped when you went from CM6 to SLIDEMEROOT5r1, all your apps would have been wiped as well including, if you have it, your ext partition on your sdcard. That's why you should always use a backup app like Titanium.

[Q] Starting from scratch?

Okay so here's my question. I've been running a variety of different roms since I rooted almost a year ago and it seems like my sd card is just full of junk from all the apps I've installed/removed as well and any number of files/folders injected when flashing. I would like to know what method I can use to reformat my sd card and wipe it clean. I guess what I'm asking is that if I boot to recovery (AmonRa) and check the options to wipe EVERYTHING, what am I left with? I'll still have the recovery along with usb mass storage capability right? If so, that would mean I could throw whatever rom onto the sdcard that way and reflash it? I'd just like to start over without any bloat at all and try to keep the card trimmed of fat. Sorry to be long winded and most likely not clear at all. Lol. Any direction would be appreciated.
Also, where is the backup information for titanium located so I can transfer it and restore my apps after all this. Thanks again.

I dont believe you can format the sd card through recovery.

[Q] Formatting System followed by nandroid restore

Hey guys,
I recently installed a new Rom, and its instructions mentioned that I need to format the system before flashing it. However I forgot to do that.
the rom works fine, but just in case, I want to format the system to make sure that i have no issues with the rom
however, i dont have enough time to have to set up my phone and reinstall all my apps and data etc afterwards (Im guessing that formatting the system will erase my memory)
so basically, Im wondering, if I make a nandroid in CWM before formatting, can i restore it after formatting so that i can have all my data back?...or will it simply undo the formatting?
i just want to know because this could save me a lot of time and trouble, however, if it does undo the formatting, then I have no choice really.
But just in case...
thanks in advance
It depends what you mean exactly by formatting. If you mean wipe data/cache then this will clear all your settings and user data (including apps).
If you say it works fine then I wouldn't worry about doing anything. There might be a slight chance that you see a problem with the rom in the future. If that's the case use titanium to backup and restore your settings and apps after clearing your data/cache.

Formatting system deletes the system partition completely.
That's all it means.
Hence:
Formatting /data and /cache
is the same as a factory reset (as it's labeled).
The Rom probably had a format /system script in there.
Some Rom devs just want you to be extra cautious.
I'm sure you're fine.
And your question about the nandroid...
No.
A nandroid will restore whatever system it backed up.

[Q] Desire have not enough space

Hi everybody!
I've a Desire with stock rom 2.3 (and no root yet) and it worked fine until last week.
If I try to install a new app I receive an error about free memory space. I've already try to move all apps to sd but nothing, I can't install anything.
I've try also to do an hard reset and fully wipe/factory reset (from recovery) and for a while it seems to works, but if I install some apps the problem come back.
Why? What can I do?
A friend suggest that maybe there are some directory in filesystem from older app (now unistalled) and, since I haven't root permession, I can't remove them. With root permission can I fix it?
Thanks!
I flashed a custom rom on my desire which used the sd card as internal storage. Problem solved.

Read this guide to s-off, and install a custom recovery
Use this guide to create a 1gb ext4 partition on your sd card. No swap.
Download a custom rom from the htc desire dev section and flash it. I would recommend milwilds redux rom. It will automatically install apps to the parittion and you will have space.
thanks for reply!
I'd like to fix this problem without flash new rom, eventually with root only. It's possible?
When I bought this there was space enough, why now I haven't? Factory reset does not erase all partition and sistems directories?
Thanks!
Also, before you flash the Rom, best to flash recommended hboot if necessary, read the first post or search each thread.
This way you use your internal memory more efficiently.

Factory reset only deletes user data.
When you bought it, you didn't have apps installed, and probably apps were smaller back then.
What are you trying to say? That you want to flash a stock rooted ROM?

Nope.
All my apps were installed somewhere in filesystem (maybe in /system?). My question is: when I do a factory reset, what I'm going to erase? Only user data in user directories, or all content of every system directory? (of course, not system files).
I'm only trying to understand why when I bought the phone I've a "lot" of space for my app and now, after a factory reset, I've not enough free space to install more then 2/3.
Example: I wipe/fr, reboot and config the phone; then I try to install Ruzzle (16Mb),Whatsapp (9Mb) and FB(18Mb). Now if I try to install any other apps I get the alert message of free space. Same error if I try to record a video or take a photo.
I think there is something wrong..
I hope that you can read and understand what I'm writing, my english is a little rusty

A factory reset will wipe /data, dalvik cache and /cache.
When did you buy your phone? I remember that, when I first bought my Desire, facebook was only 8mbin size, and moved to sd, it only took 2 mb of internal memory. Plus, large apps require large dalvik cache. That's why your memory gets filled so easily.
You can resolve easily and keeping your stock ROM (but you'll need a FAST microSD card, my 32GB is class 10):
1) Root and s-off your device
2) Format your microSD with an EXT2, EXT3 or EXT4 partition of 1GB, then the rest as FAT32 (you can do it directly from phone using the 4ext recovery, or you can format the card from PC using a tool for partitioning which supports linux formats... I don't know if I can mention names in this thread).
3) Install INT2EXT or INT2EXT+ from recovery.
4) You'll have 1GB internal memory with no out-of-space problems.
That's all
Stock kernel doesn't support ext4 nor ext3, use only ext2 if u want to keep it.
Anyway, I believe that supernova ROM would be a much better option, it's basically stock GB made by HTC with some tweaks and script for more space.
Thanks for replies!
I still do not understand why I've no memory for apps after a factory reset; if I wipe all data, I restore all space, like when I bought the phone. Ok, apps are bigger than 2 years ago, but not so bigger that with 3 apps I occupy all space!
Anyway I'm considering to upgrade to a newer version; if I must give root permission, install tools, repartition sdcard and so on, I might as well to flash a newer version.
Curiosity: are there filesystem directories that are not intrested from a wipe? Differently, which directories will not wiped during a factory reset?
Thank you very much!

yes what your seeing is caused by the apps being a lot bigger now. Facebook is a lot bigger.
And its impossible for your apps to be going to system. You'll have to root and use a2sd

I've install over 40 apps until this problem, including big app like FB.. strange things...
So, how much memory I have?
Rom 4.x for desire has a different partitions? If I just flash a new rom (like 4.0/4.1), will I fix this problem?
Thanks!

You need a rom with an a2sd script, regardless of it being GB, ICS or JB.
Good, I will search in subforum for a new rom.
Maybe it's a bit OT, but JB rom are stable enough for daily use? Can you suggest me a JB rom with a2sd script? (or even ICS, if JB is not stable enough).
Thank you!
I use jb as a daily driver. The ROM in my sig is the most stable jb ROM I've tried. It has very few soft reboots and has decent speed. It also has a2sd. (Activated through terminal after flashing rom)
However if you really need stability, speed and reliability I would highly recommend using gingerbread. Mildwilds ROMs are great and most of them have an a2sd script as well, which is automatically activated. Try the one based on redux.

I have a similar problem to this. I own a HTC Desire that is rooted, with Clockworkmod recovery environment, and I got it running Cyanogen mod 7.2.0.1.
So I was reading around this problem, and there are several solutions. It seems the most foolproof way is to format your SD card and partition it so that you have an EXT3 partition, and a FAT32 partition as has already been suggested here.. This way you can use an app to fool your phone into thinking that it has the EXT3 partition of the SD card to use for internal storage as well as the 150MB of internal storage it comes with. I had an 8GB SD card so I did a split of 2GB for the EXT3 partition, and 6GB for storage of music, photos, etc. etc. I followed this handy guide to do it, and it worked a treat: (sorry, have been unable to post an external link as I'm a new user.. maybe I can post this later).
When I rebooted my phone, sure enough, it showed 2GB+ of internal storage, and I can install all the apps I want. However, I'm experiencing apps hanging and crashing all the time, and I know it was caused by this most recent change. Prior to this, Cyanogenmod was running just fine! I've read a bit more into since doing this, and a lot of people reckon you shouldn't use more than a 512MB SD card partition, as anything over this causes performance issues. Others disagree, and think that anything 2GB or below should be fine. Presumably the apps hanging/crashing is because there is fragmentation of data between the SD card EXT3 partition and the actual 150MB internal storage.
It's frustrating, as other than this the phone is still a very decent handset despite it's age... it's really the storage letting it down. Before I try factory resetting (again!) and going back and trying a 512MB partition, (or just going back to having only 2 apps installed!), has any one else had experience of this?
Any help very much appreciated.

well,I don't use gingerbread anymore.but I can say that you can't experience a good performance to use both internal and external (sd-ext) partitions to use and install your apps. better choice is to use one of them.use default a2sd of rom,or use another script to install apps only in sd-ext partition. I have used and tested a lot of roms (GB-ICS-JB) and I can say in my experiences, that you don't have problem to use an sd-ext partition with about 1.5 - 2 gb size.you can see the recommendation of devs in first post of topics, and they tell us what is the minimum-maximum size for the best performance. sorry,i can't search and give you the links,but I just had a really good smoothness and speed with some scripts that you can try them: like mounts2sd, ad2sdx,... you can find link of them with search. and you can use cm7 int2sd version...but it has a bigger size than normal cm7. here is this topic : http://forum.xda-developers.com/showthread.php?t=1357257
@kmanpilkers
Which guide did you use to partition, should be done with gparted or 4ext recovery.
-Ext4 should also be slightly faster than ext3.
-Anything up to 2gb is sufficient. Don't know where you read about limiting it to 512mb. The whole idea is to be able to install more apps on the partition, 512mb will fill up a lot quicker than 2gb...
-you can use space more efficiently by s-off and changing hboot, so you have more than 150 MB of internal. You are currently on stock hboot and have a lot of free wasted space on your /system partition
-depending on your Rom, stick with a single a2sd script, it may be built in or need to be activated, read the Rom thread. Then let it do it's job to move apps to the partition

[Q] Wiping ALL data?

Galaxy s3 T999 tmobile phone.
Liquid Smooth ROM. - Amazing rom btw. I cant thank those folks enough for their brilliant work
TWRP for recovery
Ive done numerous dalvic/system/cache/data wipes through twrp in preparation for new roms. But my INTERNAL 16 gb SD card always shows that i have around 12GB USED. thats with no personal apps installed
Heres my question. How do i remove all unnecessary data thats hogging up space. I want a CLEAN space to work with!
I do have 4 twrp recovery files (4gb worth of data?) stored in there. Im assuming the system uses about 3 gb's. plus the gapps and liquid rom are only 194 mb combined. So that accounts for maybe 7 or 8 gb
So how do i do a totally clean wipe without losing twrp, recovery files AND root!
the only wipe option ive never used is USB-OTG. (USB On The Go?) No idea what it is or what it does. so i never messed with it. Ive read that it acts like a driver of some sort to allow usb devices to communicate with each other..
Ive also never gone into the Format data section of twrp out of fear that i might wipe the wrong things and render my phone useless
One article i read said that i might have to revert back to stock? im hoping thats not so. And do a factory wipe. Is that different from TWRP's functions? Im assuming that i would lose root.
they said din flash to stock
Odin master clear (or wipe SD from settings)
*2767*3855# on the phones keypad ...(i think codes in general only work on stock TW)
Do i have to format the sd card? would i lose important partitions that would delete the recovery system?
any ideas? i considered opening a partition wizard app to see the different partions on the internal sd card.
I'm no expert on this, but I think that Liquid Smooth has a place in Settings to let you view the space allocation of the storage in your phone and external SD card.
Go to Settings > Storage (or something similar) and take a look at how much space is being allocated of each of the different types of data. It might give you a better idea on what might be taking up that additional ~4GB of space.
If you can, provide us with a screenshot of the Storage screen. If not, you can just type them here so we can better understand what might be going on.
Back up internal sdcard to your computer.
Wipe data/factory reset.
Wipe /data/media.
You can do this through TWRP. Won't lose anything except contents of your internal sdcard. Which is why you back it up first.
Don't forget the formatting of the filesystem does this. Just like windows a 100gig hard drive formats to a smaller amount.
