Some beginner questions - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

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.

[Q] How to ensure a clean ROM install

After playing around with several ROM / kernel combinations I am looking to return to the latest stock Rom. I have the PC36IMG file on my SDcard and will be installing via ClockworkMod recovery. What is the proper procedure to ensure the cleanest possible installation? Im a bit scared of all the options in recovery such as all the format options in the partitions menu. Do I need to format everything? Will any files be carried over? I know I will need to re install Clockwork and SU app just want to make sure everything is as clean as possible. Thanks in advance.
cleanest possible? Flash this in recover. It wipes 100% of every every time.
Courtesy of Calk.
If you are just changing kernels, choose wipe catch and delv catch.
Changing to a different rom you need to wipe everything.
Thanks for the tip. I am running a custom kernel so I'd be looking to wipe all of those files as well as the ROM. The ROM I am using is just a re packaged RUU, does the RUU completely wipe all data or will I still need to manually wipe?
You should always manually wipe. I never count on something else to do it for me. When I am changing roms I always wipe data/factory reset, cache and davlick, plus I use calkulin's format all tool that the other responder to your question attached to his post. That way you know nothing will be left over. Before you do all that, remember to make a backup of your current configuration just in case something goes wrong. I have been bailed out by nandroid backup a few times.
Also one more thing, there is a Rom on here that is the latest stock already rooted which would make it much easier on you. You could just wipe and flash and still have SU and all other benefits of having root. Just a suggestion.
I found the stock rom thread. It has both odexed and deodexed version. Odexed will probably boot faster, but deodexed can be themed and/or modded. Heres the link: Stock 3.70 EVO Rooted
I reccommend clearing the cache, and then wiping the dalvik to ensure a clean rom. After that, just flash your rom. As always if you are unsure, you can backup your SD card.

Superwipe question?

Is it only necessary when coming from ICS to JB or is it necessary to do when coming from a JB ROM to another JB ROM? In my SGS2 days it was factory data wipe, wipe cache, wipe delvik cache, and maybe a kernel cleaning script for good measure, but never touched my SD user content( PDFs, music, etc.).
Super wipe will erase everything( as indicated by the warning in CWM), if you don't think it did cuz you still see the files, try and open them, its a shell only, no content (still lists correct file sizes though???)
I found this out by trying to flash some alternate ROM firmware or kernels I had but couldn't get them to work.
Don't use those stupid superwipe .zip's.
They're running the same scripts as your recovery runs...potentially multiple times for the "LULZOMGCLEAN" factor. [Uh...not needed]
Even installing a rom wipes /system...but %90 of people say "lul wipe /system/ /data/ /cache/ /dalvik/ and then flash superwipe..."
(Yes, I realize a script has to be run for the .zip to wipe system...and the Rom dev MAY leave it out. Personally, if the developer of my rom doesn't even make a "wipe system" script in the .zip I would not use that rom.)
NOT necessary.
If you don't trust your recovery to do it's job...wipe everything with one wipe...
Maybe you should get a new one.
Jubakuba is right but rather than assume the ROM zip wipes /system I find it easier to just wipe it. I never have the problems that others do when they flash ROMs and I always do a factory reset from recovery and wipe system. And if a ROM requires Gapps I always reflash the Gapps after a new ROM update. May not be needed but has saved me from problems before and only takes a couple seconds. Wipe zips are for chimps.

You have to flash Gapps after flashing a rom as they reside in /system/
FYI!

Right. Many ROMs like CM are supposed to have a script to preserve Gapps and they say that you don't need to flash Gapps after, say, updating to a new nightly but I've learned the hard way not to depend on it.

How to do a full wipe

This is my first phone that doesn't have an external SD card and I'm not 100% sure how to properly perform a full wipe it
I know this is a noob question, but I just don't want to brick my phone.
What I Used to Do
Back in the day with my SGS Captivate or SGS2 I just put all my files on my external SD card, then via Android (Astro File Manager) I deleted every folder from the internal SD card, booted into CWM, performed a wipe/factory default, cleared cache, formatted system partition and then installed custom ROM and everything worked fine.
What I Need
I want to be sure that I don't brick it so I'm hoping that someone can give me a step-by-step walk-through of how to install CM 10.1 (or any other ROM i guess) on my phone after completely wiping it of anything on it.
What I've Tried
I used the Galaxy Nexus Toolkit to unlock, root and install CWM but unfortunately when I then installed CM 10.1 via CWM, some leftover files remained from the stock ROM.
Basically, my phone is ridiculously slow/lagging and I'm getting sick of it.
I've tried installing a custom kernel (Franco Kernel), I've set the CPU governor on Performance (1200MHz always) uninstalling any un-needed apps... but my phone is still un-usable.
Sometimes when I install the latest nightly of CM 10.1 I do an update and other times I tried doing a full install where I wipe the Dalvik; neither way helps I still get the ridiculous lag.
The definition of a full wipe:
-wipe data / factory reset
-wipe cache
-wipe dalvik cache
-(optional) format system
Then flash the rom/gapps/kernel.
Maybe you have a "bricked" phone. It has something to do with the emmc chip. How much free storage do you have?
Check it by downloading the app in the screenshot.
If you havent a bricked emmc version, then I suggest returning to stock again, and then root again. ( most clean process , as it restores all the partitions to the stock state.)
Hopefully this helps my friend!
PS: you posted in the wrong forum, don't do it in the future

That's not related to development, read the rules next time.
Try the full wipe zip from Android Revolution HD Rom.
Use the pinned guide for fast boot. Use fast boot format/erase commands for all partitions, and for good measure flash to stock with fast boot also. This is the most surefire way and it hasn't failed me yet.

Thanks for the info, I'll be more careful in the future where I post.
I have the 16GB model and 4GB free right now.
I installed the eMMC Brickbug Check app and it says that my chip is ok (sane).
My phone is definately rooted, so I'm not sure why this app says that root is required for the memory test (clicking it just launches wiki page on rooting).

If you're on 4.2.1 you won't see any CWM backups so get ES File Explorer, give it root access and then go to /data/media/clockworkmod and see what's about. Or boot into CWM and delete some old backups
As for a full wipe, I use this before flashing a new ROM:

It totally forgot about the CWM backups
I'll delete those ASAP
There wasn't a lot in the backups folder but there is about 3.82 GB in the blobs folder in the clockworkmod folder; are those ok to delete?
Flash the newest version of CWM (6.0.2.3) as it doesn't use blobs any more. Delete all old backups and take a new one if you want. Also, check when I added to my last post

Thanks a lot, I'll give that a shot tonight.
I'll update CWM to the latest, then run your super wipe zip followed by the latest CM 10.1.
Thanks a lot for the super wipe zip too.
After wiping and flashing go ahead and run fix permission too.

Thanks guys, my phone is usable again
You guys are awesome.
What I Did
- installed the latest CWM using fastboot
- booted into recovery
- used adb to sideload your super wipe script, then the latest CM 10.1 nightly and then the latest gapps
- fixed permissions via CWM
- restarted my phone to get a very responsive phone again
With my last 2 phones I was spoiled having external SD cards so that i never had to sideload or use fastboot (I let Odin do that part).

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):
http://forum.xda-developers.com/showthread.php?p=43635198#post43635198
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.

[Q] Clean-up internal SD

I have two G3's that I have been flashing different ROMs on for the past six months or so. One is my primary phone and the other one is one that I picked up at a good price on eBay last October. The second phone is now my "play" phone. What I would like to do is clean-up the internal SD on both phones since free space is down to about 2gb on each one.
When I flash a ROM I generally do the following using CWM recovery –
1) Wipe data/factory reset.
2) Wipe cache. I know, it is redundant because the above wipes cache.
3) Wipe Dalvik
4) Format /system
Here is the info on both phones.
Phone # 1 -
This is my primary phone.
1) Phone is running on Straightalk's AT&T sim.
2) Modem is UCDMG2
3) Bootloader is UCDMG2
4) Probably will take phone to the UCUEMJB modem and the UCUEMJ2 bootloader
I know that I can ODIN back to stock or use KIES (not KIES3) to go back to stock. It is my understanding that this will totally redo everything. Is that correct? Does going into Backup & Reset and then factory data reset do the same thing. What is the best and easiest way? I want to get back to 4.1.2 or 4.2.1 and go from there avoiding the OTA of 4.3 and the infamous MJB bootloader.
Phone # 2 –
My play phone.
1) Phone currently does not have a sim card in it.
2) Modem is UCUEMJB
3) Bootloader is UCUEMJB
I know that I cannot ODIN back to stock because of the bootloader. I know that you need to use KIES3 with 4.3. However, will KIES3 work to go back to stock 4.3 if there is such a thing. Already bricked the phone once by mistake which is why it is on the MJB bootloader. So how do I clean-up this phone?
Again, bottom line is I just want to clean-up the phones freeing up space on the internal SD.
Thanks for any advice given.

I have the same problem man, my internal memory is still growing even though I've flashed other ROMS and wiped the data. I'm pretty sure there must be a way to wipe the internal memory on the recovery, but I've been too lazy to backup all my stuff to do it.
I've done it through recovery under wipe internal storage in twrp. I just went through the folders and made sure i wasnt deleting anything i was gonna miss later. Things you want to keep move em to ext sd or pc. Sure there's a similar option for wiping in cwm.

So it would be as simple as adding format data to the list of things I do when flashing a ROM. I was wondering about format /data but didn't want to really screw things up.
1) Wipe data/factory reset.
2) Wipe cache. I know, it is redundant because the above wipes cache.
3) Wipe Dalvik
4) Format /system
5) Format /data
I will try this on my play phone. Like this. No worrying about bootloaders and faster and easier than ODIN or KIES.
