Need help flashing ROM on I545 - Galaxy S 4 Q&A, Help & Troubleshooting

Hi it is the first time I am flashing Android ROM. I have done some reading already. Before I start, I still have a few questions and also want to make sure I am doing it right.
I own the Galaxy S4 Verizon I545. It is running Samsung ROM Android 4.4.2, Baseband I545VRUFNC5. My goal is to flash a new ROM with recent Android versions, hopefully 7.1.1 (but I would settle with Marshmallow if that is more stable), it can be close to AOSP, I don't need ROMs with extra features.
In my understanding, the bootloader is locked, it will only load signed kernels and recovery. And then the kernel would load the system. In order to flash the system, it is best to flash the recovery first with TWRP. TWRP is modded with loki hack so it would load with the locked bootloader.
So here are my questions:
1. Does it matter which firmware/baseband I am currently on? For some phones (LG G2) I heard newer firmware fixed the loki hack. Should I update to the latest Samsung rom or leave it at NC5?
2. I don't see many ROM posted for the i545, which one is the most recent and reasonable stable? The Cyanogen website is down, should I try LineageOS?
3. I see different instructions for flashing TWRP. Can I flash it with just Odin? Some instruction mentioned rooting the phone first with KingRoot or other root, and then use dd. Does the phone have to be rooted? (I prefer not to if it is not necessary)
4. If after I flashed recovery, it fails to boot into TWRP, what can I do to restore everything to default?
5. The kernel will be untouched in the process right? I am only flashing recovery and system ROM, and the kernel will work fine with the new system ROM?
Here are the step and software I plan to use:
0. reset the phone to factory
1. use Odin to flash TWRP 2.8.7
2. download a ROM compatible with I545 and place it on the phone
3. flash the system using TWRP
Any feedback would be appreciated.
PS: Also I have a LG G2 D801. I would flash that phone instead if it is easier. I just want to get started and learn some things along the way.

Oh Sorry. Didn't notice there is another forum. Should I repost there?

Yes.

1. Yes, it does matter. As you said, newer firmwares have fixed the exploits which make the phone harder to hack.
2. Any ROM should support your phone. They are generally unified.
3. In the name of anything holy, do not root with KingRoot. If you want to root, then the only way to go is CF-Auto-Root.
Rooting is sometimes necessary because recovery won't always install with Odin.
4. Flash stock ROM.
5. Kernels are specific to ROMs. So no, the kernel won't be untouched.

[Solved] Best way to root a completely stock D801?

Just got my T-Mobile G2 a few days ago and have been looking around at the different ways of rooting it. I know the T-Mobile variant is harder to root and run a custom ROM on because IORoot doesn't work on the KitKat OTA, so I haven't updated it yet. Right now the phone is running the D80110C firmware.
What I'm asking for is a way of being able to get the phone to the point where I can flash any 4.4.2 ROM compatible with it (even if it needs patches). Looking at both dr87's guide and utesred's guide, I'm thinking I need to take the following steps:
1. Root the 4.2.2 D80110C firmware (currently on the phone) with IORoot.
2. Install latest version of TWRP. Need suggestions on how to do this.
3. Reboot into TWRP, wipe everything (minus internal storage), flash SmiLey497's 4.4.2 ROM and the SU file. I gotta do this all in one go or it will complicate things.
4. Reinstall TWRP using AutoRec.
5. Go on to flash something like CM11 or Mahdi-ROM.
Any help is greatly appreciated!
EDIT: Alright, I got it! Just followed my guide and the recovery install method suggested by XxZombiePikachu and everything worked great.
Can anyone assure me that this will work? Or even share a quick run down of what they did? Thanks!

that is all correct also install recovery guide
Ok, everything's rooted and running just fine! Installed CM11 and the KitKat modem with rotation fix.
For anyone who finds this thread in the future, here's the zip of stuff you need to flash TWRP the first time, just make sure to pick up IORoot25 as well, since that's what I used to for the adb. Second time around (once you have the rooted KitKat LG ROM installed), use AutoRec. Here's a link to the KitKat modem you might need if you flash a ROM and auto rotate doesn't work.
I'm not responsible if you screw up your device. This all worked for me, so I'm just sharing the steps for prosperity. Make sure you ready all the threads and guides I linked or mentioned, use OEM cables, use a USB 2.0 port that is actually connected to the motherboard in your PC (not a hub, pass-through, or front case port), as well as being focused at the task at hand. Disabling your anti-virus might help too, used to have to do this when rooting older phones, so it might still be necessary.
If this does work, have fun with your newly rooted LG G2 D801! :good:

I337mvlufnc1 bootloader - What are my options?

I picked up a used GS4 JFLTECAN and the battery life on the stock rom is brutal, so I would really like to try something else. I have flashed recoveries kernals and roms before on other devices but have never had to deal with these "locked" boot loaders.
I have the I337mvlufnc1 bootloader and the most recent Android 5.0.1 OTA update from Rogers. My ROM and modem are I337MVLUGOH1
Can I ODIN TWRP at this point? Or will I brick my device?
Here's how I wound up at this point.
I have managed to root by odining SuperUserSU.zip by following these instructions; http://www.google.ca/url?sa=t&rct=j...4gA4TauS3dXnXcIOA&sig2=MHLMfY4z5M21bgTArDKniQ
I installed wakelock detector and a root uninstaller for bloatware as well as greenify to take advantage of root and try to fix battery drain issues. However I did something wrong and now whenever I boot "Package Access Helper" and "System UI" both unfortunately stop. I am also being prompted to select a homescreen every time I boot (touchwiz variants)
Rather than factory resetting to the stock firmware I would prefer to get on something different. any help is appreciated.

From my understanding with that bootloader is that it will prevent you from downgrading to say 4.3 etc etc. To be extra Safe, have stock firmware files from sammobile handy, but you should be good..... Don't quote me on it tho lol
He was successful on twrp flash, anyone watching this lol, all i337m unlocked
So If anyone else gets a used galaxy s4 here is the procedure to root and install custom recovery with the most recent OTA updates installed. There is no need to worry about any locked bootloader or anything.
Step 1: get root with Odin
http://www.google.ca/url?sa=t&rct=j&...5M21bgTArDKniQ
go to twrp.me
Step 2: flash twrp 2.8.4.0 with Odin
Step 3: flash twrp 2.8.7.0 (or a newer version if one is available) via twrp itself. After 2.8.4.0 TWRP only has .img files released which are to be flashed directly from twrp.
Step 4: Flash a rom.

Starting the root, recovery and custom ROM procedure from KitKat (D80220d-HKG-XX)

I've read pretty much every source I can find on getting a custom ROM up on my LG G2, which I haven't even rooted in the past 2 and a half years. My warranty ran out a while back and I'm getting a bit bored with stock now, and I want to start flashing, but the last time I did this was with my old HTC Desire HD.
As you can see I'm on 20d on my LG G2. It's a Hong Kong version for some reason, lol. What I considered doing was the following: update to the latest Lollipop official ROM using the LG Flash Tool (it gives me an available update to 30d); root using the rooting app, install a recovery with AutoRec Lollipop, flash a thermal recovery from the installed recovery (very scared of my phone overheating, I'm even considering putting it on a large, fast-running fan while doing anything, read too much about the phone overheating and making the screen yellow); back up my phone's IMEI data; use the recovery to install a brand new (I'm hoping a Marshmallow) ROM. I also understood that I need to flash a bootstack to change my bootloader to a KitKat, because it can be "fooled" using the BUMP thing. Is that correct? Do I even have to update my phone to Lollipop in this case? Also, how likely is it to overheat while doing all of these procedures?
Thanks in advance!
Sorry for the necroing my old thread, but I have yet to do anything with my phone. I am also still on KK. I saw that I can start rooting and install TWRP from it straight away. After that I need to flash a bootstack, right? How likely is it that I can brick myself? By that I mean what could get mixed up to get a brick while flashing. Also, has anyone had overheating issues while doing root, recovery installation and flashing things (newer TWRP, bootstacks, new ROM)?
Hi, i can understand your situation as i was in same till today, g2 with stock kitkat.
i finally installed cm13 after rooting it and the phone feels fresh.
you have understood most things right and ready now.
you dont need to upgrade to lollipop if youdont want to, you can start from kitkat itself.
few things i can tell you to begin here,
Root your G2,
for kitkat i found few good methods. Either do it via ioRoot using pc. or you can use towelroot or kingoroot apps to do it from phone itself. I used kingoroot since i didnt have a system with me. You can find these apps by searching at google, jst tyoe kingoroot. At first i was skeptical but it worked nice.
after root, you download autorec app, this is to install a custom recovery(twrp) for kitkat. you just have to install the app and run it and press install recovery/twrp and it'll do the rest.
after you have twrp installed, you need to upgrade it to latest version. For that download blastgator's twrp for your model and flash it through your recovery.
oh and dont forget to learn, how to enter into recovery yourself, since each G2 model has different method.
once you have these things you can start flahing roms. Most of the instructions on how to flash certain rom with what bootloader and bootstack etc. is written in its own thread, so you can learn that from that rom's thread that you will flash.
but basically, you need kk bootloader and lp bootstack for cm13 and above. usually both these things come in one zip. (if not you check for hybrid bootstacks)
Just make sure you are downloading things For your Model, if you try to flash different models stuff into yours, itll brick.
The autorec app, blastgator's twrp and ioroot can be found in a sticky thread in G2 general section, along with many other files and guides in that thread, theres complete index in that thread of all thing for all g2 models .
here : http://forum.xda-developers.com/lg-g2/general/05-10-index-guides-fixes-roots-t3218178
also usually the phone doesnt heat up while flashing, just make sure your battery is more than 80% before you start and itll be ok. Even if it does a little, after a custom rom itll be fixed. I suggest you try cm13 for starters as your first custom rom.
hope this helps you :good:
Good Luck ::highfive:
Thank you very much, appreciate the vote of confidence, lol.
I've actually considered installing Resurrection Remix Marshmallow. In the thread they point to the hybrid bootstack I need to install. I am on a D802 phone, so I'll be downloading that boostack. Anything I should really know before flashing that particular stack, except that I need to run the latest recovery from blastagator? Can I boot back into my old stock KK installation before putting the new ROM and Gapps on my phone and wiping + flashing, or will the phone not be able to boot that old firmware with the new bootstack? Theoretically, can the phone still get bricked even if I'm using the latest recovery + the proper bootstack? I've read that the CM13 devs don't recommend flashing bootstacks but instead using the kdz flashing method to flash the latest Lollipop release...

to upgrade from kitkat you need lp or hybrid bootstacks. they have images (. img files) that are needed for your phone to function properly., like aboot, modem, radios etc. Hybrid bootstack contains aboot from kk and everyhing else from Lp. So when youll flash a bootstack, youll need to wipe everything, except internal storage(or external if you have one) , before you can flash it. that wipe will include, cache, dalvik cache, system, data. so basically all the old system stuff will be gone before you can flash this bootstack. i hope after reading that youll know that you cant access your old kk installation since itll be wiped, therell be nothing to boot to. if youll try, it will give you errors on lg logo.
understand it like this, to install new 21 inches tyres to your car, you need to upgrade the rims to hold a 21 inch tyre right? what will happen if you just put the 21' tyres on old 15' rim or old 15' tyres on new 21' rims?
the cm 13 devs dont recommend you to flash bootstacks because most of the models took the official lollipop update, which put everything in their phone to lolipop level. since there is no official marshmallow(MM) bootstack for our phone (because no official update), everyone developed ways to utilize lollipop bootstack to function on a custom MM Rom. Since most models are already on lollipop, theres no need to flash lollipop bootstack while flashing custom rom. That step is mostly for those who are still on stock or custom kitkat based rom. So they say to get official lollipop through kdz method, instead of flashing Lp bootstack before gettig their rom. But remember if a rom developer asks to install a bootstack for their rom, you should consider it if you dont have much knowledge about it, cause if you dont follow instructions, you can soft brick, in that case youll need hybrid bootstack.
see if you are using everyhing proper for your phone then your phone wont brick. only thing that can go wrong with that condition is your execution, your steps. As long as you dont make a mistake in these steps everything will go fine.
ill explain it what you should do.
1. first root your phone.
2. when done rooting, install "root checker" from google play. itll confirm if you have root or not.
3.Then you come back here and find autorec app from the link i gave you in my previous reply. download that, install the autorec app. and follow on screen instructions and itll install twrp recovery for you.
4. then come back here again, and find blastgator's twrp, from the same link in previous post. itll be the one whih says "twrp with f2fs". download it and remember where you put it.
5. turn off phone, boot into recovery (i hope you've learned by now how to get into recovery of your g2 model). Now youll be in recovery, hit install button there and find where you put that file, flash it, then reboot recovery, youll have new recovery after that. then you reboot into system.
now upto this point, you can play along in your kk, have fun with features, say last goodbyes and all lol. Because everything stock kk related will be gone, past this point, including all the apps you have installed.
[IMPORTANT] : after rooting and installing recovery, get bootstack zip, rom zip and gapps zip files downloaded and placed together in a folder on your phone, before you start with flashing bootstack. Because you wont be able to boot back into system after flashing just bootstack.
now you prepare for MM, boot into recovery, now since you are in kk, you need to install LP bootstack, and for that you need to wipe everything using your recovery's wipe feature.
6. in recovery, hit wipe, hit advanced, select cache, dalvik cache, system, data. [ Dont select internal storage otherwise all flashing files will be gone and youll be left with a brick.] and wipe.
7. Now hit the back button to go back to main recovery screen once wiping is finished. hit install, flash the bootstack zip.
8. now your phone has new bootloader but its still empty, like you got a body but no soul . so hit back button, hit install and flash the rom zip you downloaded.
9. now flash gApps same way.
10. once its done, just hit reboot system. no other steps needed.
11. be patient, first boot takes longer than normal boot.
12.enjoy MM :highfive:
you probably know these steps from all the reading but its for your reference, so you dont screw up at all and be safe from bricking.
you can get google apps from opengapps website. you need to get ARM-> 6.0 -> (your prefered ones) pico/nano/micro/etc.. pico has the least amount of gapps, all important ones are there in pico, then extra will increase as you go up from pico to stock. stock has all the gapps. size will also increase as you go up. so choose as you prefer.
now once you have a cm13 /MM based rom, you wont need to flash bootstacks for other roms from next time unless the developer instructs to do so.
good luck

Does the cwm mm come pre rooted? Or unrooted ready from whatever idiocy I'm ready for?
1.stock
2.root
3.autorec twrp
4.upgrade to blastagators 3.0.2-1> or a different version I'm missing? This one says blastas twrp bump
5.put cwm rom, bootloader, gapps <where to get gapps zip?> onto internal memory somewhere familiar to me
5.wipe all but internal memory
6.flash bootloader
7.flash rom
8.flash gapps
9.???
10.profit
Check my steps teacher? I'm gonna start it anyway when my phone hits 80+ percent

cwm is clockworkmod, its a custom recovery. i think you meant CM 13, mm rom.
yes, the Cyanogenmod team have placed root access into the rom, so once youll be finished wih installing cm 13 rom, you can just go to settings, Tap build number repeatedly until a message will show "congrats you are a developer now". that'll open developer options in main setting screen Go into that and youll see root access. turn it on. youll have root.
you can check in root checker app to confirm root access for confirmation. you wont need super su app in any of these roms anymore.
your steps :
stock
1. root
2.autorec (for installing twrp on your phone) for kitkat its on forums, for lollipop its in google play. just get the one for your model, search for autorec in google play.
- blastgator's twrp requires you to have any version of twrp beforehand in order to install his version.
3. download and save blastgator's latest twrp, when youll go to download his twrp, itll be written there which one's is the latest version, just download that one and flash it through recovery.
4. Yes place all files in your phone, you can get gapps from opengapps.org/
select arm- 6.0- whatever size you like(, pico is lightest contains all essential gapps, stock contains every gapps)
5. wipe yes.
6. flash bootstack
7. flash rom
8. flash gapps
9. once gapps done, just hit reboot system.
10. enjoy
yes go for it when you have more than 80% battery, this is to ensure that all flashing steps go through without any issue, you dont want your phone to run out of juice while flashing rom do you that could cause soft bricks. so always keep battery more before flashing.
[IMPORTANT] : remember to read instructions of the rom you're installing and adjust the steps as instructed in there.
Goodluck :highfive:
Awesome, I forgot to.flash gapps prior to something I just did, not sure if it will cause increased global warming or thermonuclear war...update soon
@MarshisnotMellow
Gapps installed!! No Internet connection on the d800 and something sinister has happened to my unlocked WiFi Hotspot so I'll have to check for play store capabilities later!! Thanks for the help!!
I decided to go with the latest 29.10.2016 nightly of CM13 for my first run on this phone. Everything went through, no one died, lol. I'm going to start installing and restoring stuff now, get Xposed on, like I have on my TF701T tablet and trick out my phone's appearance. Just a note - after you install new bootstacks your phone's MAC address will change, so if you have a WiFi network with a MAC filter you might want to add your new address.

had to give back note 7 so im resurrecting my note 3 thats still on mje/4.3

I was wondering if someone could give me a direct answer because i cant seem to find one sifting through the forums.
I originally rooted with root master back when i got the phone. it is still on mje/4.3 stock build. things look a little more complicated then i remember, since my phone hasn't seen an update in over 3 years. I originally froze the verizon ota updates with tibackup, along with all the other bloatware.
My main questions are:
1. I would like to get a 6.0 Rom that looks like the note 7 did, can i do it all with odin and just flash a bunch of files?
2. Do I need a custom recovery like twrp or cwm?
3. I've read about an activation lock but can't find it in my menus, did it not exist yet on 4.3?
If anyone can point me in the right direction I would appreciate it, I really dont wanna brick my phone.
I'm still on MJE firmware, but using an older CM13 (temasek) ROM. So it's marshmallow but no Touchwiz or other Samsung add-ons.
Here are the MJE-specific issues:
1) You can't boot N* or O* stock kernels because of differences in the way that DTB (device tree blobs) are packed into the boot image. I've played with re-packing the boot images, but the kernels seem to run off into the weeds after a few tens of seconds.
2) TowelRoot works on MI9 through NC2(leak) but I think not thereafter - if you wanted to avoid a bootloader firmware upgrade but re-flash via Odin the MJE firmware for "starting from scratch" purposes, you have a means to re-root that does not require a PC.
3) If you retain the MJE bootloader, use the TWRP (hltevzw) -4.3 recovery; the -4.4 recovery will not boot, presumably due to issues similar to (1) above.
4) Not specific to MJE - but important - is the fact that if you want to boot either a custom kernel or custom recovery, you need to unlock your bootloader first. You can unlock your bootloader from any rooted ROM, but be aware that flashing stock firmware with Odin thereafter will re-lock the bootloader.
If you were to "start from scratch" but upgrade to more recent stock software before rooting, be aware that there is no publicly available root for NC4 or NK1; you would need to install stock OB6 or OF1, and follow that by using those "yemen" rooting tools. (Are they safe to use? I don't know frankly)
I am assuming that the N* and O* series bootloaders are backwards compatible with regard to device tree booting issues (see #1 above), because the temasek CM13 roms (having a custom kernel) boot on both OF1- and (my) MJE- bootloader phone. I guess that means it uses a "4.3" DTB packing in the boot image.
You are probably going to want to use TiBu to make important backups, and also copy everything off the phone that is important to you. You should assume that if anything goes wrong, an Odin re-install and factory reset are in the device's future.
Having said all this, I'm not sure there is such a thing as a ROM which "looks like Note7" - this is an old phone with almost no ROM developers left. There might have been more, but the bootloader unlock was achieved 2+ years after the phone's release, and most of the active developers moved on to new phones before that happened.
good luck

Noob Questions: Firmware,Bootloader, root.

Hi, i just got the moto g5 plus, i always have phones that from the moment i bought them they wouldn recive any updates, so i realy didnt care if unlocking the bootloader installing new recoverys will affect the OTA updates. So i have a couple of questions.
1- first i want to at least have a stock firmware just in case, but i cant figure out which one should i download from here
firmware.center/firmware/Motorola/Moto%20G5%20Plus/Stock/
Before i always use sammobile.com and it was really easy to found a stock firmware from Argentina. My compilation number is: npns25.137-15-11 this means that i suppose to download that one XT1681-XT1683_POTTER_BRASIL_LATAM_MEXICO_7.0_NPN25.137-15_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip ?
2- it is possible to unlock the bootloader and root your phone without installing a new recovery? i was reading some post and when you change your recovery or you modify something the OTA update will stop working. they are some methods like the magisk but they seem i little bit too complex for me and i don't want to do it every time that a new update is available.
thanks for the help, and sorry for my English i am from Argentina.
1. yes, but any build will flash and run, so it doesn't really matter that much...
2. Nope. You need to flash TWRP in order to root. This is because the stock recovery will only flash signed images... You can use Magisk, after backing up a stock build. Anytime there is an OTA, just restore to that system image, Flash the original recovery via fastboot, and then take the OTA. Once you have it, flash TWRP again, and restore to your other build. Or just run a custom room like Lineage or RR, and this whole thing isn't really an issue anymore.

Anytime there is an OTA, just restore to that system image, Flash the original recovery via fastboot, and then take the OTA. Once you have it, flash TWRP again, and restore to your other build. Or just run a custom room like Lineage or RR, and this whole thing isn't really an issue anymore.

yeah i know i had a samsung galaxy s3 until now, and i always have cyanogen, slimrom or now lineage, but this is the first device that i have one that will get updates (at least 1 more :S) and i want to seize that
i will start downloading that file just in case
1- ok so unlocking the bootloader doesn't affect updates only when you modify files? when the update is installing is basically comparing the files that you have with the ones that you suppose to have and if there is something different it will fail? its something like that?
2-dumb question how do you do a full backup in the stock recovery there is no option no do a nandroid backup or it will appear after i just unlock the bootloader?
