[Q] Unlocking my SGH-T999 with Jellybean 4.1 Update

Hey all,
I have NEVER tried to unlock or root a phone before, but I have the desire to try it now.
I have the T-mobile SGH-T999 with the new Android Jellybean 4.1.1 (Build Number JRO0L.T999UVDLJA)
I want to try to root my phone, but I would like to keep as much of the the new update (Jellybean) as possible instead of reverting to ICS. What I'm wondering is, what should I do to root the phone, and what programs are preffered, etc. Also, I was wondering how to back up my current build in case I want to set it back to default in case of warranty issues that I had to return it.
I am sure others have asked... maybe this would be a good sticky, I don't know... but I am hoping someone will take the time to point me in the right direction.
I need to know
a.) What I need to backup pre-root
b.) What software is best to root
c.) Any special instructions for rooting that may be specific for this build or this phone
d.) How to un-root in case I need to return the phone.
Any help would be appreciated, and apologies in advance if this is a repeated question. I just figured I'd ask because of the new update.
Thanks!

I would think the easiest is to use the root injected rom from this forum: http://forum.xda-developers.com/showthread.php?t=1771687
It is what I did and I have full root access and stock rom with no counter tripped. Backup preroot will be difficult but as long as everything is set up with google, you should be able to get all of your contacts back but not settings. Once rooted, you can use titanium backup. Great program. If you want to unroot you can use the same method you used to root but you can just odin back to the original rom again. If you like my response please click on Thanks.

Thanks!
I took a look at the thread you sent me, and have contacted the original member to get step by steps, just to make sure I dont screw it up.
Hopefully it will work as desired.

The person who wrote the thread may or may not have time to give a more detailed run-through.
I used that thread to root my phone - honestly, all the instructions have already been given in it. I have never done anything like this and I just followed the instructions as given - the process is covered completely. I'm not sure what more they could tell you.
Not trying to be rude. Just understand that they have already provided a full guide and it might be more considerate to ask questions to the open forum about any step that is troubling you - that way anyone who has free time can answer.

Ok

Thanks for that, I guess I just wanted to make sure I wasn't leaving anything to chance. Since the phone is a pretty penny, I didn't want to be screwed if I tried to root and somehow screwed up the phone.
I'll see if he responds in the next few days, if not, I'll give it a go.
thanks again!

It's so easy, you'd be hard pressed to screw it up.
Step 1): Download the Samsung USB Drivers from their site
Step 2): Download the pre-rooted stock firmware from the previously listed link here at xda(make sure you get the 4.1 with root)
Step 3): Download ODIN
Step 4): Plug phone into PC and launch ODIN
Step 5): Click "PDA" and then browse to the firmware you downloaded
Step 6): Hit Flash.
Step 7): Wait, wait some more. Wait more.
Step 8): Watch phone reboot and sweat manically as its your first time and you think you've bricked your phone.
Step 9): Tinker like a madman when your phone comes back and you see its rooted.
Step 10 through ifiniti): Continue to tinker, eventually find rom manager and aftermarket roms. some good, some bad.
PM me if you want and I can walk you through it via IM or something. I can even throw you my rom, which is essentially stock with all the tmobile BS removed.

Awesome (Easy) walkthrough

And then, if I need to send it back, I'd have to unroot the phone too, so I wanted to make sure I saved whatever I needed to. As for using yoru version without the bloatware, the bloatware doesn't bother me, since I use the Visual Voicemail, and the My Account features to manage the account for my wife and I. I just want to make sure I'm injecting the right stuff.
Thanks a lot for your help and the walkthrough above

You can always run a debloated rom and then reinstall the tmobile specific stuff.

LS990 Update Issues

hello everybody, quick question and i apologize in advance if this has been covered somewhere else or for just being a dumb question in general; I have the LG G3 from sprint and a little over a month ago i had a friend root my phone and convert it back to stock android. In anticipation for android 5.0 I removed the root. for over the past week I have been spamming the update software button and still have no lollipop. one of my good friends told me that by converting back to stock android i probably disabled the over the air updates. I was wondering about how to go about getting the updates, i have seen some posts suggesting to use the lg flash tool but I did not really comprehend how to use it. sorry if this is something stupid still really new to android.
thanks

You have to put in a valid Sprint sim card for the OTA to show up

In that case its best if you take into your local sprint store and see if they can fix it for you
I highly do not advise trying to flash the Lollipop TOT files as a fair majority of people have bricked their phone since they did not do it properly or something went wrong during the process

dont update or do anything unless you consider yourself strong minded and comfortable with rooting, flashing etc
the phone tends to get locked the moment you try to update.
So think thrice before doing anything with this phone.

Thank You for your reply, I've searched for long, and I want to update it, as long as a good guide is presented, I think it'sfine to use root and flash.

For persons that have done it (root, custom recovery, custom ROMs) it IS OK, but for people that have little to no experience doing it, reading and absorbing info thru video media is invaluable. This device can be a little balky, so heed the warnings given, STUDY UP, and be careful...

Thank you for the reply and advice, I actually did a lot of reading, and concluded that I need to return it to stock firmware, update it then flash it to read my sim card, I just do not know how to revert to stock firmawre and flash the sim card.
Any Ideas ?

How to remove t-mobile apps?

Hello everyone,
I have bought a LG G3 T-Mobile D851. I want to remove pre installed T-Mobile apps from my phone. I am new in Flashing/boot loader. Can anyone guide me how to do it?
I want to make my phone clean from useless apps.
Awaiting for your responses.
Thank you
Arfarsh

Best way is to root your phone & install a custom ROM without all the bloatware TMo put in. Plenty of how-tos in this forum, you need to spend some time & search & you will find what you need.

Hello LaserWolf, thank you for the video and clarification. I got a question, actually a couple. Before I go on to that, I am going to explain my background a little bit.
Initially I was on rooted 13a without trouble and last month my phone got into the hardware failure/bootloop issue so I had to send my phone to LG. Just got it back with 25a installed fresh. I am not sure how LG does it, push a force update after fixing or just swap out entire hardware and pushed in MM 25a straight. So, I am wondering-
1) Would it make a difference in consideration of downgrading- whether the 25a version was upgraded from a previous version vs. 25a installed fresh?
2) When downgrading, does it matter if I use 13b rooted version instead of fresh?
Thank you in advance.

to be honest i dont know cause i had a few people saying they was on 25A and it fails on them at 9% some say they succeed to 13B (not 13A) my g4 just broke and in need of a replacement and its going to cost $150 to get it replaced, screen shattered incase you wonder what happened. so i know if i get a replacement i'm pretty sure i be on 25A but i do not have the money for a replacement, its going to be months before i get it unless someone helps, i wont ask for help here as i don't think XDA will be happy with that
my phone was on 13B i did a kdz using lgup and was able to downgrade from 25A to 13B.
if its true with the qfuse what ever its called then i guess we all be stuck on MM but i will find out once i get a replacement and i redo the video if i succeed on the downgrade, you can try it if you like, the worst that will happy is it will fail at 9%

i want to give you an update. i took my broken g4 and did the OTA cause i know when i get a replacement i be on 25A, so i took the OTA to 25A then downgrade it to 13B, again. no issues and i don't why some people are having issues and failing at 9%. i want to blame it on there OS or how things are installed. i redid my OS (downgrade to 8.1. the moron at MS sucks and made 10 worst) and i did the downgrade on my g4 to 13B with no issues. i will post a video to help out with my knowledge on how to get it to work, if it fails then i do not know, all i can say from that point is to contact me, ask me to remote your PC via teamviewer and i take a look at it. please note i ONLY support the VS986
a video of proof will be uploaded here soon

i missed number 2. it is recommended that you use a fresh KDZ insted of a modified one. then root the phone, i have some root videos you can look up that will help you on 13B on my channel

Thanks for all the responses. Sorry I was not get back to you earlier. I tried but hit a brick wall with LG UP, it stopped recognizing my phone, in any way. I even removed all software/drivers and reinstall latest versions of everything, but still no go. Tried switching to various different modes on the phone. Looked up online and followed various tricks suggested at various forums to have LGUP recognize phone, but until yesterday I did not have much luck.
But anyways, I have to put the project off for now since I have faced a larger issue. Because LG wiped it clean, it prompted an activation process, which killed my grandfathered UDP (angry face emoji). Currently arguing with VZW to try to get it back. Meanwhile going to use my old rooted G2. If I don't get it back, I will sell my G4 and use the money to pay VZW's ETF. If I get it back, going to retry rooting the G4.
