[Q] Seriously desperate...

Ready to sell this phone... tried everything I know how to try... Dev Edition Verizon S5, CAN'T UPGRADE from stock NCG. The most I can do it root... any ROM I flash is nonfunctional on Verizon's network with NO SIGNAL. Replaced SIM, flashed modems, etc etc... I think I'm just not sure how to do it with a dev edition... seriously feel like I'm missing a step. Would like to start from scratch. Does anyone have a stock image of a G900V Dev Edition I could work from, since I'm starting to think the one I've been working from is somehow the incorrect version. Thanks!

I would but I'm trying to avoid locking the bootloader, if possible. Didn't intend on having a developer device, but now that I do, I'd like to try to maintain it's use as one. Bought this phone on swappa, seller didn't give any indication that it was a developer device. Now I'm concerned he did something to it prior to selling that is causing me difficulties. I don't think I should be having these network difficulties, but there could very well be something I'm supposed to be doing with the modem that I'm just unaware of. I figure if I can get back to the way this phone was when it was new (when the original seller bought it) I'd at least have a clean slate to work with.

I don't think so, but thanks... I think that's the same device firmware that the retail version comes with, which will lock my bootloader. I've actually considered just flashing it anyway and saying the hell with an unlocked bootloader, since I didn't really intend to have one to begin with and apparently there's nothing I can do with it, anyway (none of the unified builds work on my device, anyway) but this is a last-ditch effort to preserve it if i can, and I'm hoping some dev will be willing to help me diagnose my problem.

It's not like there's a ton of development going on for Dev edition. I'm loving the retail version of the phone just rooted and running some Xposed. Like it so much, I went out and got one for the wife too and I paid full retail for both to keep my old unlimited data plan. Hers I just left out of the box stock. Will be interested to see how Lolipop looks when it drops to her phone. Sure hope we keep root with Lolipop, I use the heck out of my hotspot, to the tune of about 70gb/mo ...

I'm far from a developer, but this may help. I also bought the phone without realizing what it was I was getting into and had similar problems flashing the Optimal rom on my dev edition s5. I could flash but phone would hang on the activation screen with no signal. I eventually succeeded. As near as I can recall this is what I did:
I dirty flashed Beantown 4.4.4 rom (twrp) over my 4.4.2 stock firmware. then flashed n12 firmware (included stock kernel, and modem) from dev edition make an update .tar thread (odin) (http://forum.xda-developers.com/showpost.php?p=56604757&postcount=2). I did a factory reset after flashing. Switched to art. Flashed optimal with clean reset, but did not flash kernel. Later flashed koontsez 4.4.4 kernel. Still running Optimal
Good luck.

Had marginal success using this method... Have been able to maintain a 3G signal, but no LTE after first boot. Rather, when I first booted, I had LTE and thought I was good, but since my first reboot, I can only get 3G and nothing I do can get it back so far.

This happened after I flashed the update.tar (with aboot.mbn removed) and I have note gotten LTE back. Is there something I can do with my aboot.bak that I'm missing?

New around here. Some doubts.

Hello.
Ever since I bought a Galaxy Nexus and found XDA, my life changed. Without noticing I got infected a virus: addiction to Android.
My Nexus got outdated quickly and now is pretty done and I need a new toy. 3,5 years later I finally got some spare money to buy a new phone. Since here in Portugal the minimum wage is around 500€ and top flagship phones cost around 700€ (and there's no affordable contract to get something cheaper and still nice), I had to wait until now to get a used Note 3 for 300€.
I love the phone's design and above all the specs. There's no other phone with 3GB RAM and Snap 800 for this price and I always liked big sized phones.
Well, I write too much unnecessary info... I need to stop
Let's get down to the point. I will get the phone tomorrow!!
TL;DR
How do I check the bootloader version? I want to flash TWRP right away and maybe install a Note4/5 port or something stock Android, do I need to be careful with the bootloader?
I know from other phones (i.e LG G2) that any custom rom uses KK bootloader and the stock roms use their respective version bootloader. Is this also true for the Note?
Also, which version of TWRP should I flash? Does it depend on the stock rom version that I have?
Checking if the device has 2.3x GB of available RAM, if Odin and Recovery have their stock aspect and if the S-Pen works is enough to ensure that the Note I'm getting is truly original?
Well, that's all. I'm sorry if I'm asking the same questions everyone does. I'm used to Nexus so I'm afraid of bricking the Note with dumb moves. That's why I am taking my time to read every important thread and asking here some doubts that went into my mind while doing the required reading. I have no warranty (no box nor invoice) so I can't afford to mess up with the new babe
Cheers!

this app will help you confirm your phone.
then you can proceed flashing twrp and supersu, things are so easy for N9005
and Welcome Aboard

Install phone info samsung from playstore. It could tell a lot about your phone.
To make it easy as long as the phone is running with android version 4.4.2 and above you should use twrp 4.4. If 4.3 use the right one for 4.3.
Sent from my SM-G925F

White Note3 do you have? There are several versions made by Samsung.
Regardless of the bootloader on the phone, I recommend using the latest TWRP as the latest TWRP can be used to flash all ROMs and zip files. Find your device from here: https://twrp.me/Devices/
Before moving to custom ROMs, I also recommend installing the latest bootlloader and ROM.
Not sure if your phone still has warranty but if it does, I would not change the ROM or root because doing either may trip the knox counter and void the warranty.

Thanks! I'm pretty sure it has 4.4.x or lollipop. Should I update to any of those versions (just in case it comes with 4.3) first and then install TWRP?

The phone doesn't come with box nor invoice so I don't have any warranty xd
What is the number or version of the latest bootloader?

What is the model # of the phone? There is the n-900t, n9005, n-900w8, etc.

N9005, it's the european unlocked version

The model # is important when asking questions because the AT&T version of the note 3 has a locked bootloader so it's more complicated to flash custom recovery and to get root.
If you want to run custom ROMs, I recommend upgrading to the latest modem and bootloader, install a custom recovery, back up your stock ROM, and try some custom ROMs to see which one you like.
Look for the tar version of TWRP for your phone from here: https://twrp.me/Devices/
You can flash TWRP with Odin.

I'll get the phone tomorrow!!!!!
So, by upgrading to the latest official rom avaiable I'll have the most recent modem and bootloader, right?
Do I need to follow the order you mentioned: modem->bootloader->recovery->backup->croms or can I flash TWRP, backup every partition, flash most recent modem and bootloader (not sure if I can flash a bootloader) and then install croms?

No, only flashing a newer custom ROM won't update your Bootloader and Modem. You will need to flash those files separately via Odin. Then you can flash the custom ROM you want. The order is simple. Get a custom recovery first, TWRP. Then update your Modem and Bootloader. Then wipe the device from TWRP (full wipe, take backup beforehand if you need) and flash the custom ROM of your choice.

Safest way to upgrade the modem and bootloader is via ota update on a completely stock unrooted rom with stock recovery. After the phone is running the latest rom, then start with customization.

I have the phone and managed to update it to 5.0 -> n9005xxugboa1
Is it the latest version or should I update it to another one?

BOD2 appears to be the latest according to sammobile.com: http://www.sammobile.com/firmwares/database/SM-N9005/

I'm from Portugal but the phone is unlocked (no carrier) and they only have firmware for carrier notes... Which one should I download and flash?
Also... with a G2 I flashed a .kdz file (official rom) and ended up with a bricked phone (later fixed via warranty), but I have no warranty in this phone, how can I make sure that the file is safe?

Just check for software updates from your phone.

It says the phone is already at the latest version. I've cleaned framework services and checked again but got the same result.

Try removing the SIM card and moving the date ahead by two days, then try again.

Done that, no update avaiable. Connected to Kies3, no update avaiable.
Is it really in a old version? It's 5.0. Do I really need the latest version to start flashing a recovery?
Also, can I use the recovery without flashing it? I want to check if it works nicely before flashing if it is possible. TWRP can be used to flash any rom right? I'm interested in trying darklord first.

Yes, you can flash recovery without updating. I suggested updating because the update probably deals with the stage fright bug.

Questions about installing custom rom and need rom suggestions.

Hey guys i want to install a custom rom for my t00j-d. I searched about unlocking bootloader and things like that but i couldnt find something useful. First off all i have latest stock rom (lolipop) and its not rooted so do i have to root my device first then unlock bootloader then flash rom? And which rom is good at the moment? My priorities are battery life > performance > visual.
thanks for reading and answers

i have been looking around and can not find any info on what i want to do. so i am just going to ask and see if anyone can help. hope ive come to the right place.
about a year ago i purchased a blu studio 6.0 hd(d651u). it came stock with kk(4.2.2 i believe. can confirm if needed.) i pulled the stock firmware using droid tool. so i do have the original rom and scatter file. the lollipop update was available so i updated. afterwards i ran the updated rom through SuperRs rom kitchen, rooted, de-odexed, debloated... afterwards when i was theming the apks and was almost satisfied, i dropped the phone and it broke.. so i purchased another one. same make same model(d651u). only thing i see any different is that this new one came stock with the same lollipop rom that my old phone had updated to. so my question is this. can i use the stock rom and scatter file that i got from my original device to restore the device i have now in case anything goes wrong. im trying to find out if i can safely skip the whole rom pull step and jump right into getting my custom rom onto my NEW phone. i know i can use my old rom, i just wonder if i would be able to restore a brick with my original rom pull because they are the same device, just manufactured at different times. any feed back would be GREATLY appreciated. thank you

no, you should not use the backup from another phone to restore your new one. and you should post in the section for blu studioinstead of here, the info you get here might be inaccurate

I'm scaring to brick my phone. So how to backup all things ?

Hello friends,
I would like to install custom rom on my phone Note 4 sm-n910C . I'm not an experienced person for it. But basicly I know that I need to root my phone 1st then install suitable version of TWRP on my phone. And then I can backup my stock rom and all things. Then install custom rom file.
But I scare to brick my phone doing this procedure. So I wonder, can i backup my phone's stock rom and other all things (kernel, firmware, modem etc...) without TWRP ? I mean , can do it with pc software ?
And if my phone become brick, thus, can i restore it completely via pc then ?
If i can do that, how ?
I'll be appreciate if you help me ?

Choose your Country and phone provider and download the stock ROM from Sammobile
If it's needed then use Odin to reload it. There's plenty of guides how to use it including those that explain how to root. I recently rooted one of my Note 4s, a N910C and apart from using a slightly older version of TWRP was pretty straightforward.
I used this guide and the downloaded the files from the links in it but there's other's available but be 100% sure you're following the guide for a N910C.
I'm not that knowledgeable about Rooting compared to many people on here although I've rooted all my Tablets and Phones but seem to recall you may need to use an older version of Odin to do so. The most difficult problem I had was getting the correct driver installed that would recognise all my devices and even that was just persistence. Just read everything a few times and double check you have the correct files before you start, it's pretty straightforward.
In all the above comments I'm assuming you're using the last version of the stock ROM that was released.

@Big Elf
Thank you very much for your reply and explanation. I looked at your shared pages. And I'd like to start it.
But I have some quesitons to not make a mistake. If you guide me, I will be appreciate.
But before that let me share my phone feautres screen shots. You may see all detailed information.
SCREENSHOTS
I can't share links due to xda rules bcos I need to reach 10 post. So pls complete http section if it need for below scrshoot links.
1- drive.google.com/open?id=0B6aBME5e-tzcYk1zY0dqeTZaMVk4eEdWbjN4SWVPSEU3cXFr
2- drive.google.com/open?id=0B6aBME5e-tzccHF6UFpCT29JT1ozRUFoMUtmWmZ0V0J3c19z
3- drive.google.com/open?id=0B6aBME5e-tzcajVnMGkyMTRJdmo3OTNPc29SQXlEbkY0R3N3
And My Questions
1- First of all ty for rooting page. According to explanation i'm going to root my phone. But I wonder that android version is matter or not. My phone version is 6.0.1 as you see. Is it okay, its suitable for my phone, right ?
2- As far as I read on internet, There are all TWRP versions are different for all diffrent smartphones. According to above scrshoot informations, which is the suitable, stable and latest version for my phone ? And Where can i find it from ? Or if its possible could you forward me exact page and/or link please ?
Because my scared major thing is that. Wrong type of TWRP. And so brick my phone. Btw, let me ask, wrong version lead to brick phone, right ?
If I install the true type (version anyway) of TWRP then I will be relax. Because after that, process will be very easy for me. I experienced from Huawei's first phone "IDEOS X5" . I have installed TWRP and custom roms on it , on years 2012-2013. I only scare to make mistake via perform it on note 4 & brick it.
Thank you so much again.

You've made your first mistake . I explained you need to read everything carefully and double check you have the correct files before starting so that you're reasonably confident that you know what you're doing.
The link I posted explaining how to root also has the link to the version of TWRP and Odin needed to install and Root it but you didn't read it properly.
You're running the same version of the ROM I have on my N910C albeit a different country (which won't make a difference).
If you install the Official TWRP App from Team Win you can update TWRP after rooting. I'd also suggest installing the SuperSu (Pro) App from Codingcode which will update itself after rooting. I also use Root Checker (Pro) from joeykrim to check that root has worked and SuperSu has installed correctly. All those apps are available in the Play Store. I pay for the Pro versions as I appreciate the work that's gone into them and as a thank you to the developers.
You don't have to root it so don't feel that you have to do so.
Although all my phones are rooted my Note 4s (N910Fs and a N910C) still run the stock ROM and the main reasons I did so was to run Adaway and also to debloat neither of which are essential. I also wanted to know how to do it.
Installing another non-Samsung ROM has 4 main disadvantages:
You lose the fine control over the OLED screen including the boost mode in bright sunlight
You lose some of the functionality of the s-pen
You lose a lot of quality from the camera that you won't get back with any ROM.
Most of the ROMs have some faults other than those just mentioned but are usually but not always minor.

Install non-carrier ROM

Hi All,
Complete noob here, so please be gentle!
I recently bought a new, "unlocked" LG V20 from an auction site.
The trouble is it came with AT&T carrier ROM, which being in the UK and not on AT&T means that it's stuck with the all of the branding and no access to updates.
Build number: NRD90M
Software version: H91010I
Android security patch level: December , 2016
If it's at all possible, I'd like to flash it with a generic non-carrier LG ROM, but unsure of what ROMs are safe to use on this phone, or exactly how to go about doing it.
I've looked at lots of forums and Youtube videos, but many of the links I've found are broken, or the instructions assume a level of previous knowledge that I don't have.
I'm not looking for the very latest firmware, or any trick customisations. I just want a phone that doesn't annoy me!
Can anyone advise what ROM to use, where to download it, and step by step instructions to install it without bricking my phone.
TIA

Being on 10i dirty santa method may work
I always stayed with stock rooted debloated roms on the V20. Most all the custom roms don't support the second screen or have something else I just didn't like.
I have a stock rooted Oreo thread in the developer section that I used for months until I got the PH1 [emoji16]

Use dirty santa, to unlock the bootloader and root, then you can flash 996 rom which should be unbranded

Try Super Rom. It's bare bones. No bloatware from LG or ATT.
Follow the steps here to flash TWRP https://forum.xda-developers.com/v20/how-to/root-h910-v10m-t3664500. I'm having trouble with backups fully restoring, but it works otherwise.
I'd imagine you could install Super Rom right after you can access TWRP, but I haven't tried it. I did it after flashing 10r.
Download Super Rom and put it on your SD card. Flash it after wiping everything https://forum.xda-developers.com/v20/development/rom-superv20-h918-t3764390. During the installation, it will ask you if you want to flash a kernel. Select mk2000. The speed difference is astounding. It's slow and lags without the kernel, but extremely fast if you include it. Boot system and set it up. Then go back to TWRP and flash SuperSU for root.

Wrong! Flash root immediately after you flash the rom
Sent from my LG-H910 using XDA Labs

You can just flash a US996 KDZ using patched LGUP, unticking modem. Don't accept OTA updates though

Thanks all,
Not been ignoring you - just crazy busy.
So if i understand correctly, the 996 rom will give me a stock, unbranded V20 with the 2nd screen working?
Is there any particular version of the rom to look for, or any to avoid.
TIA (again)

Update
I posted something else here, which wasn't relevant.

Just flash the newest US996 KDZ, don't worry about modem (they're both GSM only devices, so US996 modem should work on the h910, and it'll also change the unlocked-bands to US996). Use the patched LGUP from this forum, it allows cross flashing
