Hi everyone. I'm coming over from Sammyville to the land of LG, on AT&T. From the reading I've been doing on these boards, I've decided that I'm going to root the phones right out of the gate, if only so that I can use the Xposed Framework (although I assume a custom ROM will be in the cards once I get sick of all the bloatware). I just want to ensure that I've managed to piece together the process so far.
1. Accept no OTA update
2. Install LG Drivers (non-verizon version)
3. Run IORoot, using steps here
4. Download and run Freegee app to bypass bootloader & install TWRP
5. Backup the EFS partition and save it somewhere, in case I bork everything afterwards
6. Don't accept any OTA
Is that the basic idea of the path of least resistance? As I understood it, accepting the OTA updates complicates installing a custom ROM later on?

I rooted, then installed the OTA. Then but on twrp did a backup and then flashed a custom rom. I also backed up the original recovery and bootloader with flashify..
Universal drivers. Back up EFS first and foremost after IOroot and recovery(both zips in multiple copies and locations). Freege works, but I prefer flashify / Phil's CWM. Backup also original boot, recovery, and kernel. Freeze the updater app as not accidentally accept. You sir, have done your homework. Accepting the OTA can fail or "softbrick" the phone destroying recovery. Freezing works better than chance. These steps may be painstaking, but will save your ass in a mishap.
I've been poking around the forums trying to figure out an answer to this, but nothing so far has worked. My question is a simple one:
How do I root a stock ROM of Android 5.0?
First, the tech stuff:
Device: SM-N900A / AT&T
Android: build LRX21V.n900AUCUEOC1
I had Android 4.4.3 (rooted with Towelroot), which I was finally able to force to upgrade to 4.4.4 by using ODIN to flash a firmware update. In the process, root access disappeared, but my overriding concern was to get Android 5. I found a stock ROM of it here, which I downloaded and which did install perfectly.
Now, I've tried a bunch of different things to get it rooted--including trying to flash the pre-rooted Android that Walter.White posted in another thread (my phone kicks back an "invalid signature" error when I try, the install always fails and what I get is a device that's like it's fresh out of the box)--I also tried the CF-Auto-Root route, with ODIN says fails and which causes my phone to freeze. Towelroot doesn't work, and I can't get Safestrap to work either (it complains that there is no root access and there's no Safestrap option in the restart dialogue box).
I know that I'm missing something, and I know that it's probably something absurdly simple. I've got no doubt someone else has cracked this, any chance someone out there could help me figure out what I'm getting wrong?
You must go back to android 4.4.3 and root like you once did, then flash the pre-rooted version android 5.0 and you're all set. Sounds like you have everything you need, just need to do it in the right order.
I rooted my wife's N9008V which was running Android 5.0 with Kingoroot and afterwards removed Kingoroot with Super-Sume. After that I installed SuperSu.
I know that I'm missing something, and I know that it's probably something absurdly simple.
very simple .
Op you are in the wrong forum this is NOT Note 3 AT&T forum .
I rooted my note 3 by flashing TWRP through odin then flashing the SuperSU.Zip package through TWRP
The n900a can't be flashed with twrp if it has a locked bootloader.
I've been having issues with my phone, and I'm not sure if this is a HW issue or not, but no matter what I do, either I lose recovery or get a security error. I poked around and found some instructions in the CloudyG3 thread. They're for 3.0 but I would guess 3.3 wouldn't be different enough to brick this thing. Can't remember who the quote is from, I just copy/pasted it, but here it is:
Some of you sent me a PM asking for the install instructions on D800 and this is how you install CloudyG2 3.0:
Downloads:
1. Download CloudyG2 3.0 - https://www.androidfilehost.com/?fid=95897840722646001
2. Download Patch - https://mega.co.nz/#!sVY0mRTb!qn7S9B...3m_QpMQkgzunn0
3. Download Signal Patch - https://dl.dropboxusercontent.com/u/...l_Variants.zip
4. Download LP Baseband - http://blastagator.ddns.net/modem.php - d800-30f-modem-blastagator-signed.zip
5. Download KK Bootstack - http://blastagator.ddns.net/bootloader.php - bootstack-d800-KK_20c-blastagator-signed.zip
6. Optional: Download JB Bootstack in case if you want to revert the installation process and go back to your current ROM - http://blastagator.ddns.net/bootloader.php - bootstack-d800-JB_10d-blastagator-signed.zip
Flashing Process:
1. Backup the existing ROM (including EFS, Modem, etc.) in TWRP - very important and copy it over to the computer, just in case!
2. Wipe System + Data + Cache + Dalvik Cache - Do NOT select internal storage as it contains all your downloaded files + backups!
3. Flash KK Bootstack (downloaded from Step 5)
4. Flash LP Baseband (downloaded from Step 4)
5. Flash CloudyG2 3.0 (downloaded from Step 1) - Leave the default in Aroma when you have to pick the variant. Do NOT reboot the device as the patch installation (next Step) is very important.
6. Flash Patch (dowloaded from Step 2) - Select your variant.
7. Flash Signal Patch (downloaded from Step 3)
8. Reboot
Enjoy!

I'm guessing I have the incorrect files, most of the links I found in the thread with these instructions didn't seem to work so I Googled for them, maybe I don't even have the correct files. I took a screenshot in cmd of the exact filesizes.
Any help would be greatly appriciated!

you want to install cloudy g2 3.3?
this is whati did
used to root http://www.droidviews.com/easily-root-lg-devices-using-the-one-click-root-script/ if you are on lollipop it gets stuck at 90% twice after 3 attemps same stuck at 90% rebooted and it was rooted
then on playstore i used autorec canat remeber if it says v2.. but for lollipop installed and it checked my device and its said it was ready. so i just clicked twrp and it installed twrp then i downloaded blastogator twrp and installed cloudy g2 3.3 on d800 unlocked... sorry if you were refferimg to another version of cloudy..

Coming off a fresh TOT flash, I root with towelroot, flash TWRP using AutoRec, flash bootloader, then flashed Cloudy. It will boot at first, but then I run into "black screen of death" or security errors or when trying to boot to recovery, I'll run into similar issues. Does Blastagator's TWRP make the difference here?

I had the exact problem happen to me ....... I got the black screen of death .... phone wouldnt boot ....... and when i used the kk bootloader i would lose recovery ..... I was coming from kk to CloudyG2 ....
This is how i solved.
1. Flashed back to stock, stumproot to root Autorec v1 for bootloader
2. used Flashify to upgrade to 2.8.7.1 ( its now 2.8.7.3)
3. Downloaded n used bumpted LP bootstack and flashed blastagator stripped rom (its in flashable zip and installs everythin including modem .... patches etc EVERYTHING) http://forum.xda-developers.com/att-g2/development/rom-stock-lollipop-30b-stripped-t3144195
4. Downloaded kk bootstack , CloudyG2 3.3 and clean flashed in recovery
I have been enjoying Cloudy ever since ...... D800
Thanks all, got it running! Cloudyfa has done some absolutely brilliant work here with this ROM, as well as xdabbeb with the advanced camera driver and xCam. I'm usually a vanilla-or-nothing guy with my Android ROMs but this one is quick and power efficient. The KitKat ROM that shipped with the phone was super bloated and gross, but I'll admit LG UX 4.0 isn't really that offensive, plus I like the goodies like Multi-Window and QuickRemote. Once I disabled/hid some of the remaining LG bloat, it's surprisingly pleasant and not really that far from AOSP aesthetically. Again, cheers to those who provided the assist on this one for me!
... now my only question is, should I try CloudyG3?
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

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.
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.
https://forum.xda-developers.com/galaxy-s4-verizon
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.
