What ROMs can I flash, and how? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have a Samsung Galaxy S4 AT&T. An I337 with a locked bootloader. It is running Android 4.3 after I followed the downgrage guide from http://forum.xda-developers.com/showthread.php?p=50667360
So I am running a baseband version of NB1, and a build number of MK2. Everything I read says to then install Safestrap, and then flash a specific ROM that works with Safe Strap. However, under the Android Original Development, there are a bunch of ROMs that don't need safe strap and it seems like flashing regular ROMs. Why does everything I read state that I can only flash ROMs that work with Safe strap? Do the ROMs listed under Android Original Development all work with Safe Strap? I am very confused here.

More than likely NOTHING in the "Android ORIGINAL development" thread will work for you, and won't work on safestrap. Those are for those of us who got the phone when it came with MDB or MDL Firmwares that were able to use the Loki boot loader bypass. Which in turn let us use CWM or TWRP Custom recoveries. Also allowed us to flash kernels, which most if not all in the ORIGINAL development section will do/need to work.
For you on MK2/ NB1/NC1 you can ONLY use safestrap and its recovery. You CANNOT flash CWM or TWRP. You CANNOT flash kernels. So you need Roms that use the stock kernel. MANY ROM in the " Android Development" forum do work with safestrap. But do your research first. This means ONLY Touchwiz based Roms and possibly the GPE based ROM/s.
So NO Cyanogenmod, AOKP, or Other AOSP based Roms will work for you.

[Q] 4.4 Update to Help Development?

According to this article,
http://www.gottabemobile.com/2014/02/13/samsung-galaxy-s4-android-4-4-kitkat-update-detail-slips/
the update for Sprint's S4 might be indicating an update for Verizon and AT&T's variants. Would this mean more development for the Safestrap (speaking mainly about MF3+), and unlock the possibility for running the Google Play Edition 4.4 ROM through the kernel source that will be released? Or will we still be stuck with using a 4.2.2 ROM on Safestrap, and only be able to use the Touchwiz 4.4?
I have little to no knowledge about the development process for a virtualized ROM (ie: Safestrap), so any information would be awesome! Hopefully we can look forward to a stock 4.4, thanks!

Safestrap ROM's aren't special, just any ROM that can work with a stock kernel. If Hashcode can find an exploit to run safestrap on 4.4, then we will get 4.4 TW ROMs. Kernel source won't help get GPE as we can't modify the kernel on MF3+ devices.

Pretty much all stock based firmwares are very stable, as stable as stock really. Theres not really a 'best' ROM as everyone has different needs/tastes/preferences/etc, but the below two ROMs are stock based. They are based on the latest firmwares and have optional mods, but you can chose if you want to mod it or leave it alone and it will be as close to stock as you can get.
You dont really have to flash a stock odin base first, although if you are on pre-knox bootloader you could flash a pre-knox 4.2.2 stock rooted ROM via Odin and create a nandroid backup, so you have a backup option, 'just in case'.

only that, the 2 options are i9505 ....and I need 9500 versions
about flashing the odin base first?
- after 4 years and many roms ( all samsung versions )
I came to the conclusion is the best stable / unbugged way

Sorry didnt see you have a I9500..
Perhaps someone else can advise?
If it works for you flashing the odin base first then go for it. The only reason I would advise not to is if you are on the old pre-knox boot loader and want to avoid Knox. I flashed a pre-rooted MGA firmware on my I9505 shortly after I got it and used stock rooted for a while, then tried GoldenEye, which is a stock based custom ROM. Im now on the latest version of GE which is based on 4.4.2 and dont have any issues.
I would recommend checking the I9500 dev section to see what ROMs are available, the below one looks like what you may be after. Stock based with add ons that are optional with an aroma based installer.
http://forum.xda-developers.com/showthread.php?t=2662583
Im suprised that a member that is that long around asks a best rom question.
You should know by now that there is no best/bugfree rom. Every thread that has these kind of questions gets closed.
Try it out for yourself which rom suits you. There are plenty of roms to chose from.
Mod Edit
"Best" or "Recommend" ROM / Kernel threads are not allowed on XDA.
Please test these things for yourself. That is the only way you will get an unbiased opinion, and then, you can decide for yourself if it meets YOUR needs.

[Q] Can't find custom ROM for Cricket S4 'jflteaio'

Hello,
I am having trouble finding a custom ROM for my Cricket galaxy S4. Model is SGH-I337Z, codename 'jflteaio'. I have TWRP 2.7 recovery installed along with Touch-wiz ROM, Skyfall. But I would really like to have at least one custom ROM for this device. I have looked through the unified section, as well as the AT&T section with no luck for 'jflteaio'. Can someone point me in the right direction? Thank you all
Dan
I don't know if there are roms specific for that device.
The rom you mention is for a i337 right? Then maybe all the roms from that device work. Just flash them and see if they boot.
If not then you probably need to port them yourself, there are plenty of guides out here that explain how to do that.

Safestrap ROM Development

Forgive me, but I unable to find this information anywhere, so I am now asking:
How can one turn a ROM into a Safestrap ROM? For example, it would be great to have a Safestrap-compatible Cyanogenmod, but perhaps this is not possible. XDA developers, please share your knowledge and insight on this and thank you.
There's no such thing as a "Safe strap compatible Rom".
But if you are running safestrap then you need a TouchWiz based Rom, so a cyanogenmod Rom is not possible using safestrap.
and wrong thread lol. he is correct ∆
we have a locked BL so it wont flash the kernel therefore we cant flash an aosp kernel which prevents us from having an aosp rom.. closest you can get to aosp on here is eclipse rom

[Q] Firmware Updates, Rooting, Backing Up, Custom ROM Questions

Sorry for the noob questions. I just don't want to mess it up.
I plan to root shortly. I've watched a few YT vids, so I'm confident about doing that.
I'd like to about the order of doing things, if that makes sense.
At the moment, I've not downloaded the OTA firmware updates, so it's basic KK 4.4.4. But, I downloaded via SamMobile, the latest KK ROM (N910FXXU1ANK4_N910FBTU1ANK2_BTU)
Am I correct in thinking, I should reformat the phone (I've got nothing on the phone I want to keep), install the ROM from SamMobile via Odin (to be fully up to date with KK), then root and install TWRP, create a backup.
Then I'm free to install any custom ROMs, update to Lp?
Speaking of custom ROMs, at the moment I'd prefer to stick with KK, until Xposed is sorted and is easy to install when using Lp.
Without trying all the custom ROMs out there, do any support the fingerprint scanner, S Pen, Multi Window, S Health and the HRM or would I loose some/all of those features?
If in the future I upgrade to Lp, is it necessary to download/flash the latest stock ROM (to get the latest FW updates/fixes/security patches etc), before I installed a custom Lp ROM?
Thank you for any help and advice
Does anyone have any answers, before I try it and blow up my phone in a massive fireball?
You're pretty much such right on the above steps. Some (me included) prefer Phils CWR rather than TWRP as a custom recovery. Fair enough to stick with KK, but LP working ok with Xposed now, assuming you're using a custom rom. There are two distinct types of custom ROMs. Those based on touchwiz and those that aren't. The ones based on TW will be called things like BOD2 or BOE2 for LP or ANK2 for KK (like the one you pasted above). Other ROMs will be based on AOSP. The TW ones will work with the s-pen, fingerprint etc. The AOSP ones won't. You can go straight to LP custom from KK, you don't need to flash via a stock LP ROM but it doesn't harm to do so. The custom ROM installation instruction will often provide you with an extra bootloader/modem file to flash if you are coming from KK or a different version of LP. Stock ROMS do include bootloader and modem, custom ROMs generally don't.
Good luck

Thank you very much, that's been a great help Respect to the People's Republik of Mancunian :good:
A TW ROM sounds the best option for me at this time.
A few more Q's if you don't mind (or anyone else).
1. Is it worth installing a pre rooted stock ROM (for the 910F), so I can get any possible OTA updates (KK or Lp) or is it nothing to worry about?
I'm not sure if any exist at the moment for the 910F?
2. Is it best to just install 910F based ROMs? (I'm thinking about the telephone side of things, connecting to UK carriers)?
Thank you.

No prob. Yeah. I agree - go for a TW ROM. As for your questions:
1. No. OTA updates just take you from one stock ROM to next version of the stock ROM. OTA updates don't work well, usually failing, once you have rooted and maybe installed custom recovery. You can easily stay up to date without OTAs by just re-flashing with a new custom or stock ROM release. For me, the only reason to use a custom rom at present is to use Xposed (mostly to change DPI for different apps and also to add the symbols on the stock keyboard, oh and also to run a non-ads environment). If I was staying on KK I would have stayed on stock, rooted and then installed a custom recovery and Xposed. Currently Xposed is only compatible on the Note 4 with Lollipop if you are using a deodexed (custom) rom. All stock ROMs are ODEXED, and hence not compatible with Xposed (for now).
2. Yes. Stay away from ROMs for other variants (like the 910G). They're not compatible.
When you pick a ROM, ask questions in the ROM thread. It will be more read than these Q&A areas.
