[T-Mobile Samsung Galaxy S 4] No1sy B0y:
Hi.

OK, here's the thing. I installed this ROM http://xdaforums.com/showthread.php?t=2679913 on my rooted Galaxy S4, which was in Android version 4.2.2.

On the Installation Instructions, the Author mentions the following, "10. Wipe /data/, or if you are feeling dangerous, don't, then come back and wipe /data/ later if your phone is acting funny or does not boot."

I did that and now my phone is acting funny. One of the things it does is that it freezes on the Home Screen until a popup shows up saying that "TouchWiz stopped working". That has happened like 3-4 times now. Another thing that happened not long ago is that my phone suddenly Shut itself Off. The battery had plenty of Charge, yet it went off for no reason.

So my question is, I want to wipe the /data now, but what I don't know is that, will I have to re-flash the ROM after I have wiped the /data?

Help will be much appreciated.
[T-Mobile Samsung Galaxy S 4] lalec:
Yes. You have to full wipe and install again. You always have to full wipe before installing a different ROM or you are likely to have these types of problems. The OP of that thread was joking when he said you could choose not to wipe before installing.
[T-Mobile Samsung Galaxy S 4] No1sy B0y:
Thank you.

I couldn't tell if he was joking or not.

Sorry for the double post, but there's something else.

To my understanding, by wiping /data, eveything, including Text Messages disappear (correct me if I'm wrong). I have a Backup, but its a Backup of my previous Android version.

Can I make a Backup of the Text Messages only or can I Restore just the Text Messages of the Backup I have?
[T-Mobile Samsung Galaxy S 4] lalec:
Easiest way is to use free app "SMS backup & restore". Text messages are buried pretty deep in your backup and require manipulation to restore manually. But can you get your phone to run well enough to do that? If not, message back and we can help you do it manually.
[T-Mobile Samsung Galaxy S 4] No1sy B0y:
OK, I have Backup my Messages using that App. I have all my contacts saved on the ZIM Card. Will those disappear too?

There are quite a few apps in play store that will back up text messages. Just search. I've used helium before and it's pretty good.

Just export the contacts to your SD card and save it somewhere you can get again. Once you install new ROM import the contacts again. The import/export option is in contacts app itself.

Ok another stupid question, My battery graph shows upticks in reporting and im wondering if thats from kitkat or if my after market battery is the problem? Ive tried two different roms with 2 different kernels.
[T-Mobile Samsung Galaxy S 4] lalec:
Are you sure you didn't mean to say that you had version 4.3 instead of 2.3? This model phone had 4.2.2 originally (they came with UVUAMDB or UVUAMDL which was an incremental update). A few months after they were originally introduced they started shipping with 4.3. If that is what you have and you've already flashed a 4.4 ROM your easiest solution is to use Samsung Kies software to install a full ROM that includes radio firmware also (i.e., what Kies installs will include everything even radio). You will need a full install of the KitKat stock ROM to solve your problem.

---------- Post added at 07:41 PM ---------- Previous post was at 07:33 PM ----------

If you do the wipe correctly before installing the ROM there is no need to wipe the external SD card. If you aren't sure how to avoid wiping that you can shut your phone off and remove the microSD card from the slot and then proceed with your wipe and install. Just be sure that the SMS Backup & Restore app stored your backup on your external (i.e., removable) microSD card and not your internal (i.e., non-removable) SD. The SD storage is in a separate partition so it doesn't normally need to get wiped during a ROM install unless you had some software that moved apps to the SD storage. If that doesn't apply to you you don't need to worry about wiping SD. You can do a factory data reset, wipe cache, wipe data, wipe Dalvik cache, and format /system is what you usually need. I usually also wipe cache and data again just before I install the ROM and have fewer problems when I do that. Good luck!

[T-Mobile Samsung Galaxy S 4] No1sy B0y:
I was in a hurry, so I did it before you posted that.

What I did was, wipe /data, cache and Dalvik Cache, twice just to make sure before Flashing the ROM.

When the phone booted up. I followed the steps you follow when you have just gotten the phone new. So far, nothing major has pop up. The only thing that did happened today while it was charging and me surfing the web, was that the phone suddenly Rebooted. Other than that, the phone is working smoothly.

Internal Storage for SYSTEM

So the problem i have is that the SYSTEM memory usage is at 6.41 GB I will attach a screen shot.

I am currently using 4.4.2 GNF1 Sickness Style V3 ROM currently and before that i had the Wicked V10 ROM and am currently using TWRP 2.7.0.1( I've used Wicked Roms since version 3)(tried some Foxhound ROMs as well)

So I have always done a factory reset and wiped everything that DEVs have suggested. I dont know if this is just a problem with my phone (probably not). The only time the SYSTEM memory went down after flashing a ROM was when i soft bricked my phone(i went into recovery and advance wipe and wiped something i shouldn't have. Which in turn deleted duplicate system files from previous ROMs.) I dont want to go that route which i fear i may have to cause not even a Nandroid backup would make the phone work. I ended up having to go completly stock recovery and ROM.

Please Advise.
[T-Mobile Samsung Galaxy S 4] a103:
That's normal. Every Galaxy S4 has about 6.5 gb memory allocated as system memory. That's the partition Samsung has made. You can't change that. It means the usable memory on a 16 gb model would be about 9gb. Hope this helps.

If you installed a different ROM without formatting (i.e., wiping) /system you are likely to experience problems. Good work though, it sounds like you are back up and running.

I have a rooted S4 with Clockwork Recovery on 4.2.2 and I wanted to update to 4.4.2 or 4.4.4 or whatever I'm supposed to update to.

I had a few questions regarding this:

How do I go about upgrading from 4.2.2 to 4.4.X? I'm honestly just guessing, but do I odin flash to 4.4.X and then I'm free to install ROMs and stuff that pertain to 4.4.X? Is it that easy?

I also am running a custom kernel [faux kernel], do I have to worry about this when I upgrade?

What is the Knox Guarantee stuff I keep seeing? Should I really care about it?

If something goes wrong with 4.4.X, am I able to use a recovery image and revert(?) back to 4.2.2?

I saw something that updated the modem to 4.4.2 or whatever, will I have to update the modem if I upgrade to the next version? Does it matter?

Is there anything else I should be well aware of?

I'm also particularly interested in the CRT animation, where you sleep your phone and the screen cuts out like an old CRT TV. Most Roms that offer this are somewhat bloaty and change the icons needlessly. The only mod I could find was for GT-I9500 http://xdaforums.com/showthread.php?t=2309530 but I couldn't tell if it would work on my phone. If I flash this, will this just kill my phone, or will it just soft brick, and it will just display the "Samsung Galaxy S4" graphic and just loop [letting me just test harmlessly, I can just recover]? Is there an alternate way I can get this CRT animation? If I upgrade to 4.4.2, could I just flash this, even though it's not in the T-mobile forums? http://xdaforums.com/showthread.php?t=2510196
[T-Mobile Samsung Galaxy S 4] a103:
I'll try to answer whatever I can -

To update to 4.4.2 please visit this thread http://xdaforums.com/showthread.php?t=2816508 and Odin flash the 4.4.2 firmware. Once you flash that you'll be complete stock and lose root access. However you can root again and install custom recovery. And then flash custom ROMs again.

You'll lose the existing kernel because you'll get the stock kernel in the process.

Regarding Knox - you are currently on 4.2.2 means you have old bootloader without Knox but once you upgrade to 4.4.2 you'll have new bootloader with Knox abs and if you install a custom Recovery on new bootloader you'll trip Knox flag which will void your warranty. Once the flag is tripped it can't be reset so please think twice before you trip it.

You can very well flash 4.4.4 custom ROMs with your current set up as well however few people experienced data drops with Kitkat on old bootloader.

1. you can either flash 4.4.2 firmware via Odin or

2. just flash the modem via Odin. You'll get the modem here - http://xdaforums.com/showthread.php?t=2678774

Again please make sure that you are on old mdl bootloader before flashing the modern from above link. Also make a nandroid back up just in case. All the best.

I hope this helps.

i also have a question about the modem. my S4 was 4.3 with the MK2 baseband and i rooted it and installed twrp manager and was able to install slimkat, so im running 4.4.4 but i would like to use the newer NB4 modem

i keep seeing links for the NB4 modem (just a couple of posts above) and that you must be on the MDL bootloader to use it. how do i know if i am on the MDL bootloader and can i just pull the modem.bin from the NB4 firmware and use that with odin? not worried about knox and its already tripped when twrp was installed
[T-Mobile Samsung Galaxy S 4] a103:
Since you mentioned that you were on 4.3 it means you were not in mdl bootloader. I'm not sure about pulling the modem.bin part. But you can just flash the stock nb4 firmware that way you have latest boot loader with modem and since you already tripped knox it shouldn't be an issue [emoji2]

Once you flash 4.4.2 firmware there is no going back. You can't flash anything lower than 4.4.2 which means even if you have a nandroid back up of your 4.2.2 ROM it'll fail if you try to restore or even soft brick (I'm not sure) so would advise you to not try [emoji6]

Secondly the mod is for i9500 so don't flash at least I would not flash as it's not meant for the phone and hence not tested on it.

Thank you for helping me-- by the way, I got everything working and my phone is safe and sound.

I did restore it to my nandroid backup though-- and it recovered OK. I only went back when I deleted my app backups on accident when I cleared data-- It ran OK enough for me to get backups and flash the firmware again.

I am not going to flash the mod-- instead I will try xposed module because I saw there was an option for CRT animation there.

Thank you so much!
[T-Mobile Samsung Galaxy S 4] lalec:
No, just follow the steps mentioned previously. Depending on which recovery you use the menu options will look a little different but basic steps are (after you backup any settings and data you want to preserve) factory reset data, wipe cache, wipe data, wipe Dalvik cache, format /system, (optional: wipe data and cache again here), install ROM and on first boot leave it alone for at least 5 minutes while it rebuilds Dalvik cache, etc. Good luck.

So after I pay off what I owe on my S4 to T-Mobile I'm thinking of switching to another carrier that will let me take my S4 with me. I assume I will still need to flash T-Mobile ROMs and Kernels, right? Or will I have to find Kernels and ROMs that are made for the company I switch to? Or do I need to go back to stock and be stuck?

If it helps with any answers I'm thinking of switching to Cricket and I've already checked to make sure my S4 is compatible with their services.

A question about MDL modems...

Hi folks,

I'm the happy new owner of an M919 that is still on 4.2.2 MDL stock ROM. In case I ever need to flash its modem again on top of a custom ROM, what's the best one to use? I'm really quite confused. I've found lots of links with what seems to me to be at times conflicting information, much of which is six months to a year old, and may be outdated.

There was this thread: SGH-M919 T-Mobile MDL Modem

It seemed straight forward but a bit surprising that I would have to ODIN the modem instead of just flashing it in recovery. So I thought it might be outdated.

Then there was this thread: Modem / Radio Collection (M919 I9505) Odin Flashable MDL

But then it went all into data drops and sound problems and mixing bits of MDL and MK2 modems... I'm not sure why I'd ever have to do that...

So, now, in August 2014, and given that my unit is 4.2.2 MDL (no Knox, yea!), but I will be flashing ROMS that are mostly 4.4.4, what modem should I flash, if I ever have to flash any? And, can such be flashed in recovery or is ODIN a must for that step?

I'll actually be using it on ATT, but it is SIM unlocked and it's working fine on the ATT network so far as I can tell from some quick tests.

I'm about to install TWRP recovery and then install a unified ROM, Dirty Unicorns.

Before I do it, I want to make sure I've got all the bits I might need. I did diligently search for the answer before posting, and perhaps came up with too many answers... so please help me out to make sure I'm up to speed. Thanks!

Marc

PS: My ignorance comes in part from the fact that I'm migrating from an ATT I337, with locked bootloader, and I'm "used to" safestrap and only being able to flash non-kernel bits, which had to match up with the kernel, so I'm re-learning lots of things now!
[T-Mobile Samsung Galaxy S 4] a103:
You'll need to Odin flash the modem. One can't flash it through custom recovery. Since you have SGH-M919, this is the thread I used to flash latest NB4 modem -

http://xdaforums.com/showthread.php?t=2678774

You can flash the modem before or even after flashing the 4.4 4 ROM of your choice. Please note that people reported that NB4 modem doesn't stick if you flash it once in such cases you'll need to flash it twice [emoji6]. You can go through the thread above before you actually flash it.

Hope this helps

Thanks! (and, Thanks via clicking button :good: )

I figured, since I'm on an unlocked bootloader, I could use pretty much any modem, with probably the latest NB4 modem being presumably the best, if I need to flash any at all. But doing it via ODIN as a requirement is a bit of a surprise, though it's no big deal. I've seen the thread on needing to double-flash the NB4 modem... I'll re-read just in case I need it.

Hopefully the unified ROM will work out of the box for me without any need to redo the modem, but I'm all about being proactive with this stuff.

I appreciate the fast response.

One last question:

I'm still unclear on one point. The thread you referenced is just for MDL bootloader... and it seems like MDL bootloader + certain modems/radio combinations = loss of sound or connectivity issues.

While I understand that the MDL bootloader doesn't have Knox, and others do, I still don't quite get why the bootloader version should matter on our systems that allow full flashing of the entire ROM+Kernel+modems ... what part does the bootloader play in modem compatibility?

Sorry if I'm being dense... I'm clearly missing something, just not sure what.

LTE is tied to the bootloader
[T-Mobile Samsung Galaxy S 4] Frankenscript:
Ah! Now I get it. So, for any given bootloader, there is a matching, required LTE radio (NON-HLOs.bin), which is independent of the modem.bin GSM modem. LTE Radio must match bootloader or else bad mojo happens, but modem.bin can be updated at will, with consensus being that NB4 modem is the one that makes sense for people running modern 4.4.x ROMs.

Have I got it?

Stock NB4 (4.4.2 OTA) Capable of Cyanogenmod?

Hey, I'm probably going to buy a used T Mobile S4 tomorrow, and I assume it will be running the latest stock NB4 (4.4.2) firmware. Is the bootloader on this version unlocked? Basically, I don't care about tripping knox at all I just want a phone that I can flash Cyanogenmod or another non-Touchwiz rom on to. From what I've read in this thread it seems like it won't be a problem, but I just want to be really, really sure before I buy.

I'm paranoid because I bought an ATT S4 without doing my research, only to find that it was stuck on Touchwiz forever thanks to the bootloader. I sold it today. I don't want that to happen again.

It seems like the process, if possible, would just be root, install TWRP recovery, flash CM11 and GApps. Is this correct? Do I have to worry about Loki or anything?

Thanks in advance for your help!

P.S. Apparently I'm not the only paranoid former ATT S4 owner in here... Maybe we should start a class action for PTSD lol.
[T-Mobile Samsung Galaxy S 4] Frankenscript:
I feel you! There's no suit but there is an open petition, over in the ATT forums somewhere.

Per my messages recently in this thread, I just bought a T-mo M919 and am about to go flash happy. Note, unlike ATT, there's no need to root it before putting recovery on it. I just learned this. As long as you don't mind using ODIN to flash TWRP or whatever, you can just plug the phone in and go. If you want to install recovery via GooManager or the like, then you do have to root first.

Yes, that's it. I use the NB4 radio on my main phone which still has a 4.2.2 ROM on it.
