Hello.
I have G900V with unlocked bootloader (15xxx Samsung eMMC).
Can I use ODIN to flash one of G900F firmwares from sammobile.org ?
Will flashing it actually turn my phone into G900F?
Are there any risks in doing that?
Will bootloader stay unlocked and can I keep root?
I'm not using the phone in the US, so I don't care about CDMA support.
As I understand it, flashing a stock bootloader will re-lock the exploited bootloader. The key will be to flash, in a custom recovery or Odin, ROMs, firmwares, recoveries etc that do not include bootloader image files. I'm sure these ROMs will become plentiful very soon.
I am also looking for the same solution. I also have a Verison G900V, rooted, bootloader unlocked phone in India. I also want to upgrade it to international varient G900f. Please help on how to do.
If you have a Verison G900V, rooted, bootloader unlocked phone that runs 6.0.1 you can flash international variant G900F roms from a custom recovery(TWRP) and than if you use CDMA flash the Jrkruse's patch from here http://forum.xda-developers.com/ver...pment/4-4-4twinternational-rom-patch-t2897026 to have data and mms working . If you try to use odin for firmwares that are not from Verizon you might hardbrick your phone.
OK
Right now I am on MM6.0.1 with rooted and unlocked bootloader on S5 G900V . How to install TWRP so that I can flash custom patch. Right now my recovery is stock.

Will flashing G900F rom again lock the bootloader?
It will not lock your bootloader. Will only install a custom recovery. You can find TWRP here http://forum.xda-developers.com/gal...recovery-twrp-2-8-6-0-touch-recovery-t3107535 . Use odin and select the PDA tab or button to browse to the tar file that you downloaded and flash the device. I'll recommend you version 3.0.0

I currently have AT&T stock (I used to have a custom ROM then had to flash to stock ROM to be able to flash to another custom ROM--however, I accidentally flashed a newer version of the AT&T stock ROM which locked my bootloader and I could no longer flash to a custom ROM). I updated my AT&T stock ROM recently and now my back/menu buttons don't work, so I want to see if I can flash to a custom ROM now.
I don't remember the procedure to flash a custom ROM--do I first need to get root in order to unlock the bootloader to be able to flash ROMs (i.e. if I have root then I am guaranteed to be able to unlock bootloader in order to flash ROM)? Is the baseband version the only thing that determines whether I can unlock the bootloader and then be able to flash ROMs?
I currently have OK2 as broadband version and checked one of the stickied threads which said this:
" ROOT
OK2 -- No direct root method. Must Odin OC4 kernel, use Kingroot, then Odin OK2 kernel back."
Does that mean what I have to do is use Odin to get OC4 kernel, then use Kingroot, then Odin OK2 kernel and then I will be able to have root, which means I can then unlock my bootloader and be able to flash to ANY ROM (not just TouchWiz-based ROMs)? Is there anything else I need to consider or is this 100% foolproof? In the future, what should I be careful of in order to prevent getting my bootloader locked again--just that I don't flash a stock (AT&T) ROM that is known to lock back the bootloader?
Thank you all!
There's no way to unlock the bootloader if you have updated your device to the lastest firmware version. The only thing you can do is flash SafeStrap and use Stock Kernel Based ROMs which are compatible with Safestrap.
As regards to the procedure of rooting an OK2 firmware, I'm afraid I won't be able to help you.
Have a happy new year.

I was just about to sit down and flash a stock ROM. Can you explain what you mean by this? Did you flash OK2 and it caused you a problem?

It was a while ago but I used to have I believe an MDL broadband version which meant I could flash any ROM available. I tried a different ROM, didn't like it, then decided to flash back to the stock ROM but accidentally flashed a newer version of it, which meant that my bootloader is now locked. With a locked bootloader, apparently I can only flash to a newer stock ROM (not other ROMs like Cyanogenmod) via Safestrap.
I think if you don't have the MDL broadband version you shouldn't worry about it anyway because it is locked and you will only be limited to flashing stock ROMs.
Slight correction
The previous entry is not entirely correct. Like the OP, I was originally on an unlocked bootloader on my i337. I'd purchased my i337 on the first day and eschewed OTA updates. I wanted to try a touchwiz based ROM, Hyperdrive, and in doing so I recall flashing the stock NB1 firmware. Every firmware beginning with NB1 has a locked bootloader and there has been no progress for more than a year in unlocking the bootloader again. This can limit you to either stock ROMs OR other touchwiz based ROMs like Hyperdrive. I love the Hyperdrive ROM (now on release 21) but its developer has moved on to a newer phone, so it's stuck at Android 4.4.2 and no one has picked up the project in many months. There are several other touchwiz based ROMs for the i337 version of the S4 which I have also tried but I prefer Hyperdrive's myriad customization, even without proper patching. I'll be moving on soon to the Nexus 6P as my daily driver, but would very much like to keep my S4 up to date with a custom ROM. Given the number of people that have been in this same situation, where a newer stock ROM from AT&T locked a previously unlocked bootloader, it's been surprising that the issues have not been overcome on a phone as popular as the Galaxy S4 was and continues to be. I've seen unlocked versions of the S4 selling for just under $400 in the last week of 2015.
Use the desktop version of Kingoroot to root and use Super su and update the binary. Don't forget to hit thanks if this helped.
The bootloader for the at&t s4 was never unlocked. The MDL bootloader had a flaw in it that allowed you to use LOKI which is a lock bypass, not a way to unlock the bootloader.
Hello friends now my gti9505 have custom lollipop rom.UHOJ2 base modem and bl.one suggest me can I flash custom kk base rom?any problem after flash kk base modem bl over on lollipop modem and bl?

A custom rom never contains a modem or bootloader. So no that does not apply.
It mean no any problems after flashing?
Some custom ROMs require an up-to-date modem and bootloader. If you flash a custom ROM, the imei may disappear or wifi/calls may not work if the ROM is too new for the phone's bootloader and modem.
Before installing a custom ROM on a phone, I make sure that the phone is working properly with the latest stock ROM.

He means it the other way around. He wants to use a kitkat rom on a lollipop bootloader and modem. That's shouldn't be a problem.
I see the OP asking 2 questions:
1) Can a KK ROM be flashed to a phone running an LP bootloader and modem. Generally, I would say yes but whether all functions work will depend on the KK ROM. Some custom KK ROMs I ran on my Nexus 5 required me to downgrade the bootloader and radio to KK versions.
2) Can a KK modem and bootloader be flashed over an existing LP modem and bootloader? I think it depends on the phone's installed bootloader.
Yes audit13 brother my quistion is no1. I have now albe95 astra v2 on UHOJ2 base modem and bl lollipop. And goes to goldfinger kk base.now confused what can I do?
Did not try on i9505 but it works on i9500. I think it will work but u should backup your EFS partition
I say try the KK ROM on the LP bootloader and modem. If it doesn't work, you'll either have to find another ROM or you'll have to try and flash a KK bootloader and modem over a LP bootloader and modem.
Dear All,
If I want to flash any custom ROM do I need to unlock the Bootloader, or flashing TWRP Recovery through Odin will be enough to flash any custom ROM. The Model of the device is GT-I9505.
Thanks.

Only Verizon and AT&T models have locked bootloaders.
If your device is none of the above you should be fine with just flashing recovery through Odin.
Thanks dear.
Hi, I have recently rooted and bootloader unlocked a G900V and it works fine on Lollipop roms, but when the device is flashed with a MM rom via TWRP or Flashfire the Wifi wont work. IDK what is up with this. Maybe it has something to do with the baseband or whatnot, I'm out of ideas so I have to bug you guys for help, thanks in advance!
A little more Info I'm on PF4 baseband. Tried the Note5 port rom, the BS free rom and a deodexed debloated MM rom and all have no wifi. Ive tried the phoenix kernel, still no go. Tried flashing the PD1 baseband as its another MM baseband and it didnt take (via odin or TWRP ¯\_(ツ)_/¯) . So idk why flashing basebands doesn't work, maybe it'd solve my problem.
By using Getex's [GUIDE] Unlocking the Galaxys S5 Bootloader using DEV Bootloader [KK-MM]
and following the bottom subsection (If You Already Have Bootloader Unlocked And On A Samsung TW Rom) I was able to fix the problem.
Nice! Thanks GETEX!
Hello.
I have Samsung galaxy s4 (i9505) locked to orange UK. It's on lollipop 5.0.1.
I have tried unlocking it by the tutorial but i have read that the menu is locked on my device.
My question is would i be able to unlock it by flashing older firmware (and if im safe to do it)?
Regards
Try this: Flash a 4.2.2 modem, root, run regionlockaway, flash 5.01 modem.
