Hi everyone. My phone is rooted and has Safestrap Recovery. I've been anticipating the Android L update for some time and have been used the better part of my weekend trying to figure out how to get that experience. However I'm near my wits end and thought I might as well just ask the experts.
Has anyone tried or know of any way to try out the new update? I've tried a Cyanogenmod 12 rom with the Safestrap Recovery on a new partition or "slot" with no luck. I'd prefer some method that'll let me flash a non-stock rom so I can have the ability to tether (I'm on a T-Mobile sim card with an unlocked phone).
Any advice would be greatly appreciated.
I have also tried a Lollipop ROM, specifically the GPE one, with no luck. We unfortunately cannot use Cyanogenmod, due to the locked bootloader which prevents using custom kernels (SafeStrap is like a workaround, with some limitations). It's only a matter of time before the official Lollipop update rolls around. By then, there'll hopefully be a Safestrap-adapted GPE 5.0 Lollipop ROM.

Months ago I flashed my phone (AT&T S4 I337 running MLD baseband) to stock 4.3 ROM (JWR66V). I have TWRP installed as a custom recovery and the phone is working fine. However, I don't have root access when the OS is running. No sure why.
Anyway, I'm bored and there are a few nagging bugs, so want to give Cyanogenmod a shot. My questions for you are.
1) can I just download the appropriate CM release and flash it?
2) Do I need to reroot? If so, whats the best method for me?
If its really risky, I'm not interested. But if it's a matter of just flashing the rom, I'd like to give it a try. Any advice is appreciated. Thanks.
Hello everyone, I'm considering T-Mobile's LG G2 as my next device over the Nexus 5, but I've heard the latest update locks down the phone preventing the installation of custom ROMs. Is this true or am I misunderstanding something? Basically, If I were to purchase T-Mobile's G2 preinstalled with latest updates would I be unable to install ROMs like CM11 or AOSP at this point? I apologize if this has been answered before, but I haven't been able to find a clear answer and I am anxious to get my next handset.

Yes and no. When you get your G2, it will have Jelly Bean on and not KitKat. So with that, you can root/install recovery and flash CM11 or any other ROM you wish to. But if you choose to update your phone to TMO's official KitKat, there's no recovery yet for that at this point. But you can always downgrade back to Jelly Bean, I've done it numerous times.
Good luck!
Actually there is no way to install recovery on Kitkat. Only way is to have the phone running JB to have root and recovery but there is a way to have recovery on kitkat but for you to have that you have to have jb on your phone first. It have something to do with JB bootloader on kitkat. If you buy your phone and have kitkat. downgrade to jb root flash a recovery. and now most kitkat roms have these patches so you can keep recovery while on kk
Hey Everyone!!
Thank you for looking at this thread.
In a nutshell, I got my i9505 galaxy s4 since June 2013, rooted it straight away when i got it, its got twrp recovery, and im on omega v9 4.2.2. Havent touched it since to date
It does not have knox.
Is there a way I can simply upgrade to something like cm 12.1 with 5.1.1 with everything working, by simply flashing latest cm with gapps using twrp, or will I have to upgrade bootloader, radio, get knox, or even just start over, flash stock samsung lollipop firmware with knox using odin, in order to do so?
I already a while back tried updating twrp to latest, and tried flashing cm with lollipop 5.0 when it first first came out, but only 2g was working, and signal would cut if i lock my phone. Im guessing this is due to bootloader/radio incompatibility, or maybe because it was early builds? Apparently i cant flash lollipop bootloader and radio over old 4.2.2 stuff without consequently installing knox? Is knox that bad? I heard its better to not have knox but if its the only thing stopping from lollipop then so be it.
Any help and advice much appreciated.
Hope to hear soon,
DJ
You can try upgrading just the modem to be able to flash an Android 5.x ROM, but it likely will not work and thus you will have to flash an updated bootloader as well. The good news is that since your S4 is out of warranty, whether you trip the Knox flag or not will not matter.
You should be able to flash the updated bootloader and radio without having to install an entire ROM, though you might want to download the latest ROM for your S4 anyway. There is a thread in I9505 General that has a list of bootloaders and modems that can be downloaded and flashed through Odin. From there, you should have no problem flashing the custom ROM of your choice through recovery.
Hello,
I have a rooted i337 with MDL baseband, running stock 4.2.2 firmware. I am currently out of the US and therefore cannot receive any OTA. I want to upgrade to Lollipop or Marshmallow based custom ROMs, esp those that can still use the IR feature of the S4.
Can anyone guide me on how I do this upgrade, without bricking my phone? Would truly appreciate your help. Thanks.
Have you tried running ota updates via wifi without a SIM card in the phone.
To run a custom rom, you would need to install a custom recovery to flash the rom. Some mm and LP ROMs may not work with a 4.2.2 modem and bootloader.
If you want to use a custom ROM, DO NOT take any OTA updates. If you take an OTA and it is successful, then you will no longer be able to install a custom ROM.
Here is the Cyanogenmod thread to install CM to your phone: http://forum.xda-developers.com/showthread.php?t=3008609
If you would like to update to official ATT/Samsung lollipop(there is also a way to have root)[remember, once you take an official update from MDL, then you will no longer be able to install a custom ROM and you may never be able to get Marshmallow]: http://forum.xda-developers.com/showthread.php?t=2926642
My younger brother has a Note 4. It was previously on Kitkat 4.4.2, stock rom, rooted with dual recovery...
He wanted to manually update to either a 5.1.1 Lollipop rom or even 6.01 Marshmallow.
After having tried several 6.01 roms, the phone either bootloops or the sim card is not reading...
After having trying to flash the radio & bootloader to flash via odin, it keeps failing when trying to do so.
Could someone please recommend a simple Lollipop rom or Marshmallow rom that actually WORKS and the sim card is read as it should?
With my current Sony Z2, it is so much simpler, flashing any roms automatically comes with the kernal, radio, recovery, root, etc...
With Samsung it is much more complex and finding a rom which comes with everything seems difficult to find.
Some roms even ask to choose a kernel & modem/radio. How the F**K do i know which one I need? Even when selecting one it results in a bootloop.
I'm not interested in overclocking or using a custom kernel. I just want something that works and any 5.1.1 rom or Marshmallow rom would do. I want something as close as stock as possible. Not interested in Cyanogen mod, custom roms or such.
Thanks!!
you need to flash a compatible modem for your model number and version of android. If it helps, I'm using: N910FXXUICOL2 with Marshmallow
I have the N910F model.
Hmm, I don't know why you are having problems, actually its Samsung where you can simply flash a ROM with Odin, no need of ADB or anything.
You just make sure that you COMPLETELY WIPE your phone before flashing a stock ROM via Odin. You should not have any problem at all, no one should, unless its hardware.
