S4 wipe data internal or external etc

Helping my aunt do her phone to add google edition rom 4.2.2 i know how to root and install cwm but I know I need to transfer the rom do I need to transfer it on sd card because wipe data factory reset will delete all internal storage? And using that rom do I need to flash the tmobile kernel?

You need to flash the T-Mobile kernel, if you want to put the ROM on the internal SD card simply flash it first then wipe.

It doesn't matter whether you put the ROM zip on the external SD card or the internal memory. Before you flash a ROM you want to wipe cache, dalvik, data, and system.. not after. Wiping those partitions won't touch your internal storage; though it is true that if you want a clean slate after flashing the GE4.2.2, you could go through the steps, then wipe internal storage only AFTER the flash.

Can you link to me the tmobile kernel I want to make sure I get the right one so I have no problems and
it's only the ge edition 4.2.2 and 4,3 needs tmobile kernel right but the rest don't?
and wipe data factory reset deletes internal right?
So flash first then wipe data factory reset?
Sorry for the excessive questions I'm only used to doing my lg optimus

Download the Rom you want to flash.
If it is not for the SGH M919 (T Mobile S4), you will need to also download ANY SGH-M919 Kernel.
Cut out the middle man and just grab a GE rom from the T Mobile Development Thread.
(I recommend this one):

Throw the rom onto your external SD.
I recommend wiping everything for a clean slate, especially because you are changing everything about the phone, (data, factory reset, caches, internal, system).
This rom specifically gives you a nice little Aroma (or customization) while flashing the rom onto the phone.
Hope this helps.

T-Mobile kernels are in the Original Android Development section here. And no, it's not JUST the 4.2.2 and 4.3 needing TMO kernels; it's ANY Galaxy S4 ROM you flash outside of the T-Mobile development section. Best way to remember, if you download it from the T-Mobile section, no need to flash a kernel. If you download the ROM from any other S4 section, you WILL need a T-Mobile kernel. Also worth noting is that there are kernels for TouchWiz and AOSP/CM. A TouchWiz kernel will not work on AOSP/CM and vice versa. The GE 4.2.2, having the TouchWiz framework, can use any of the TouchWiz kernels here (not AOSP, also useless information if you d/l from the TMO dev section); but I won't comment on what kernels the 4.3 can use as I'm not exactly sure.
And as for what to wipe, it depends on what recovery you're using; I haven't used CWM in almost a year, so if you use CWM my recommendations may be a little off. I've used TWRP ever since it was ported to my previous device, so my directions are from using TWRP; the only time internal storage will be wiped is if you select it from the advanced wipe menu. None of the other options (dalvik cache, system, data, cache) will wipe your internal storage. If you are simply changing between different TouchWiz ROMs, there is no need to wipe data. The data partition should work fine between all TouchWiz ROMs. If I'm switching between TW ROMs, the order I use is to: wipe dalvik, system, and cache at one time; then flash the ROM and, if the ROM isn't for the M919, flash kernel. The only difference in my method when moving from TW to CM or vice versa is that I format data also. I haven't experienced too many problems saving data between ROMs of the same type; i.e. ParanoidAndroid and CM, or different versions of TouchWiz... but if you're moving from a CM variant to a TouchWiz ROM, it's really a good idea to go ahead and wipe your data partition.
And as always, if you experience problems in any ROM you flash, try wiping everything (dalvik, system, data, and cache) and trying from a clean slate. Another thing to keep in mind, if you use TiBu to backup your apps and data, there can be problems if using app data between CM and TW. When you restore, be sure to check App only and not App+data. I definitely wouldn't recommend interchanging app data between 4.3 and ANY version of 4.2.2.

TWRP - is DATA backup necessary?

Hi,
So the official 4.3 ROM UEMK8 was released today for my Note 2 n7100.
I'm currently running UEMK4 4.3, so I thought of backing up everything through TWRP before backing up, as the file I used to flash Odin with (the leaked 4.3) is no longer available as I deleted it by mistake.
so as I'm backing up, everything works but DATA gives me error tarring split files.
so is DATA backup necessary? can't I simply just install the K8 ROM , then if something fails I just wipe my data/cache then restore System and Boot? as I don't need the DATA inside, unless DATA is part of the OS and I MUST have it.
thanks

No one replied.
Conclusion:
No, just perform full wipe.

Some beginner questions

I have a Bell SGH-i747m.
Is it ok to flash i747 roms to an i747m? I've been doing some reading and it looks like what could go wrong is that it could change the modem. In that case can I install any i747 rom and if I find issues change the modem following the info from this thread?: http://forum.xda-developers.com/showthread.php?t=1831898
I've already installed Cyanogenmod using the automatic tool. Can I flash roms while Cyanogenmod is installed or should they be flashed from a stock firmware? (as a side note I have installed and flashed Clockworkmod Recovery)
Are there any issues flashing roms based off of other carriers? (Rogers based rom flashed to a bell phone)
How do I make sure I'm not downgrading my bootloader and bricking my phone?
Finally, are there any comprehensive lists to find nice custom ROMs and their features or is it just kind of a game of picking through the forums? What are your favorites or what are you using currently?

I'm not an expert but I'll try to answer your questions.
You can flash i747 ROMs onto an i747m but you cannot flash i747 modems and bootloaders on an i747m.
There is no need to return to stock before flashing a new ROM. You may have to wipe cache, data, Dalvik, and system before flashing the new ROM.
You can flash stock Rogers and Telus ROMs to your phone and it will work.
Make sure you are aware of a file's contents before flashing to ensure the bootloader and modem are designed specifically for your phone.

Imo, modems should never be included with a rom. And thankfully I have never come across one, so you dont really have to worry about that.
I agree with audit13 on everything but one small point. Unless under specific circumstances, I dont feel formatting /system before flashing a rom is a good idea. All roms do that as the first step in the flash so its already covered that way. But more importantly, ive seen lots of people format, then have an error and cannot flash their rom. They are then left with no OS on the device. Ive also seen several times where they ended up having to flash their firmware via odin and start over completely.
I know some will disagree with me on that, but I just dont see any real benefit to manually formatting the system partition.

Thanks guys
I'm looking at Dirty Unicorn http://forum.xda-developers.com/galaxy-s3-att/development/rom-dirty-unicorns-t2844362
Assuming I don't have to worry about the modem, is there anything I have to worry about with the bootloader? I don't see one specified and I don't know what bootloader I would have right now.
Also I've been reading that gapps are just google apps. It sounds like you just flash the gapps file the same way you flash the rom. Is this right?
And lastly, is there ever any issue with flashing a rom thats based off an earlier android version than the one you are currently using?

From a terminal windows, this should tell you the bootloader on your phone:
su
getprop ro.bootloader

Thanks
My bootloader is I747MVLUEMK5 . Looking in the about phone section in settings that is the same as my baseband. Are the bootloader and baseband related? How would I tell if its compatible with Dirty Unicorn?

Look at the updater script in the ROM as it will tell you what bootloaders are supported.
You can always try flashing and see of it works. Make as nandroid before flashimg the new ROM

I was able to flash DU and I'm using it now, however I'm experiencing some huge battery drain (25%/hr normal use)
I think its possible I did not clear everything correctly before I flashed. I've read the old rom can conflict with the new one if its not completely wiped which might kill the battery. I did a wipe fata/factory reset, wipe cache partition, and wipe dalvik like most guides described.
Reading the post on the DU G+ space https://plus.google.com/u/0/communities/109738128866939227235 however, it says
6. Wipe everything. This doesn't mean just system or factory settings. This means EVERYTHING!
Tap on Wipe/Advanced Wipe and check the following and swipe to wipe
- Dalvik Cache
- Cache
- Data
- Internal Storage
- System
- MicroSD (some devices don't have this option)

I'm not sure how to wipe data, internal storage, micro sd, or system. I saw there were some options to format these areas in CWM, but I didn't want to do anything hasty.
I'm also confused because if I format both my MicroSD and Internal Storage I will have deleted my rom file, and my phone doesn't seem to connect to my computer while in recovery if I need to put the file back on the phone.

Choose "format data". This will wipe the entire /data partition including your internal sd card, so make sure youve backed up everything first!

Thanks! To be clear, this means I'll store my backup and rom on my external SD card and direct CWM to the zip from there?

If you are asking if you need to store your backups on external sd, yes. It wont touch the external storage unless you specifically tell it to.

Stock Backups

for some reason my stock backups from the virgin ndc do not boot after i use a lp or mm rom. im using twrp 3. Someone posted about the stock backups not restoring but no help in that thread. clean wipes do not work either.

Clean wipe means, also wipe internal storage. To boot a KitKat ROM or restore a backup after lp or mm, you must wipe everything except external sd. It's the way lp and mm encrypt the internal storage.

Are you sure you're wiping internal? Not just wipe data, format internal (data/media) storage. Do it twice if you have to. If you've definitely done that, then your backup is corrupt. Because once you wipe internal (and data and system) you've removed all traces of mm or lp. So the previous rom has nothing to do with FC. Are you trying to restore titanium backups of apps from mm onto kk? Don't.
Also, have you moved apps to external sd on any rom? If you have, and not properly removed that data, it can cause problems.

no the fcs happen right at boot. dont see how my backup is corrupted and yea ive wiped internal storage. not that much of a noob lol just new to this device. what i did was restored with ndc tar and then flashed twrp then booted back to stock to make sure everything is ok. Then make a backup then clean wipe again to install lp or mm roms then if i do another clean wipe and restore stock backup fcs on boot.

[Q's] Custom ROM flashing

Hey,
My LG G3 currently running Android 5.0 (V21-SEA-XX), rooted, lastest TWRP flashed with AutoRec.
I want to CLEAN flash nightly CM13 and I have few questions:
1. After downloading ROM and GApps, where should I put them? Internal memory/SD card?
2. What should I backup in TWRP to get full backup? and where should I move the backup to before wiping?
3. What do I need to wipe to get the cleanest install possible? I own my G3 for over 2 years and it has a lot of junk on it. (of course without wiping the SD card)
4. Anything special you recommend me to backup with Titanium Backup?
5. Do I need to flash Modem? (My device is running 13.00002)

1. You can put them wherever you want. In internal or sd. If you are wiping internal, don't put it there
2. You can do a full backup using TWRP if you want a full backup of your current Rom, kernal, apps and so on. But it's not necessarily needed of you're sure that you don't mess things up.
3. A normal wipe(dalvik, cache and system) on TWRP is quite enough for installation of a rom. But if you want to wipe internal you can do that as well.
4. If you're not doing a TWRP backup, you can backup your apps using titanium backup. This is what I normally do, because I only usually need a backup of my apps and data, and not of the current rom(because we can reflash it later of needed).
5. You need to flash a 21B modem. Usually changing from stock based to cm roms requires change in modem.
And one more thing, you're just flashing a rom after 2 years [emoji15]
G3 D855---ROM : #DU ---Xposed

Thanks.
Few questions -
1. Why not flash 21C modem?
2. Can you tell me exactly what do I need to wipe in TWRP to wipe everything except SD card?
System, Dalvik, Cache, Internal Storage.. Data too?
