rooting - G2 Q&A, Help & Troubleshooting

Hi
I am going to root my G2 for the first time. its currently on stock jellybean.
I would like to know if I should root now on jelly bean and install a custom rom or upgrade to stock kitkat first and then root?
if I am going to a kitkat custom rom would it make more sense to upgrade to stock kit kat first or is it easier to root from jellybean?
What are the advantages/disadvantages of either?

Hi
Can anyone advise on the above? I know I should be reading all the forums which I will but was just after a quick general answer so I know where to start from. I'm not new to rooting and flashing roms but I am new to the G2.
Thanks

I would recommend updating to Kit Kat first then rooting using IOroot25. That way you will have the latest radio/modem stuff to use KK Roms

Depends on the ROM. If the dev says you have to have Kitkat modem or other stuff from Kitkat, then update and root with ioroot25. If not, it will be a waste of time, so:
Download anything you need from the new ROM and put all in your phone storage (so that if you accidentally brick you still have files to flash in your SD), root, install recovery (I suggest TWRP) and from there flash your ROM!

What are my options I am MDL and Rooted

AT&T S4 with 4.2.2 MDL. I rooted it way back when. I have CWM recovery installed. No AT&T Updates have happened because they always fail At the same time what are my options for getting 4.3 or for that matter when 4.4 comes out?
I have bloatware still. Use root for backups and a few other root required apps. I've run custom roms before when I was on my HTC Evo 3D. If I install a custom rom will I loose my current root / status?
If you want a stock rom minus bloat...

For a stock international rom

Or... Google Edition rom, no sammy features

I would use these as starting points because they're modded slightly and if you want more, explore other roms.
Make sure you update your recovery to avoid any errors in flashing. You can also flash to the latest radio and revert if it doesn't work for you.
You won't lose root. You already have recovery, so you can always get it back.
There are 4.3 custom roms out there, there are people who want an S4 that came with MDL. I'd flash a custom 4.3 rom. We can even ugrade (flash) our modems to MF3, MJ5, MJ6 and flash back to MDL without ruining the phone like those who took the upgrades prior to root and got screwed by Samsung.
Do some research like above and for gods sake dont unroot your phone and take any OTA updates or you will regret it.
Just my advice.

[Q] Root using ioRoot25?

Hey everyone!
I just got my AT&T G2 last night.. I like the phone, but really want to root and ROM, coming from a gnex.. its a bit bloated to me
Anyway, it was 4.4.2 out of the box with firmware verison, D80020c. Originally I thought I would need to revert to stock firmware D80010d? However now I have been told I can just use ioRoot25 and then flash Cloudyfa's AutoRec recovery? Is that correct?
I'm going to get at this, this afternoon but obviously it would save a lot of work if I could just use ioRoot25 but as I said, I want a custom recovery also so I can flash a non-stock rom.
Please let me know what would work, and what works best.. Thanks, Chris.
I've went ahead and downloaded supersports tool to revert to stock D80010d. I haven't actually ran it yet, because I want to wait on input from people in this thread. However, it seems like rooting with ioRoot on D80010d, flashing custom recovery, and than flashing a ROM would be the way to go.. It is my understand that currently it is no yet possible with KK to have custom recoveries? Being on stock KK doesn't do anything for me anyway.. I'll probably just flash a asop based ROM running 4.4.2 anyway and go that way with it.. So it would work like this..
Currently on D80020c (KK) --> Revert to stock, D80010d (JB) --> Root using ioRoot (any verison would work I guess?) --> ADB flash over either CWR, TWRP, or Philz recovery? --> Get some 4.4 based rom with gapps, flash it and all is well? Then I will be rooted and romed with a kitkat based rom correct? And all in time for the weekend?? lol.
Right on. Use ioroot25, but apart from that you've got it all figured out. You're right there is no recovery for pure kk because they patched the Loki exploit, but there are work arounds. Everything you need to know about rooting and flashing had been covered here so just go ahead and do your thing and enjoy your new phone :good:

Can I install CWM on the GS4?

Hello, I've been out of the rooting scene for over a year now since I bought my Galaxy S4. When I first bought it, i had it rooted but could not install a custom rom because it was on MF3. So, once again I am trying to get back into rooting with the latest OTA update and a NC1 baseband. I've been looking around on how to root and install a custom rom but I've been gone so long that I'm just lost.
From threads I have read I can downgrade my phone to NB1 then to MK2 to root. However, I haven't really been able to find an answer to if I can install a custom rom to it, only upgrading back to the OTA and keeping root. I have been having massive overheating problems with the stock firmware and have a large burn mark on the back of my phone and would like to switch back to CWM which i had on an old phone.

No CWM. You can only use Safestrap, a variant of TWRP for locked bootloaders that doesn't flash kernels. Due to that restriction (if we tried to flash a custom kernel we'd get bootloader check fails) we can only run ROMs which the stock kernel supports, meaning other Touchwiz ROMs and the one GPE that's been posted in the General section. Part of the downgrade and root process is using Safestrap to update to 4.4.2 with a modified OTA, and so you just replace that step with flashing a ROM, the kernel modules, and then the ODIN files.

[Q] Xposed on locked bootloader and Rolling back questions

Hello all,
I recently installed 5.0.1 rooted on galaxy s4 I337 using muniz's method and had some questions?
The main reason I rooted was to try to get xposed so I can edit the ui, I understand that it is not working on samsung devices right now, but when it does work, I understand the only way to install it is using a custom recovery.
Since I have a locked bootloader and am on 5.0.1 I don't think there is a way to get a custom recovery on here, correct me if I'm wrong.
How would I install the xposed framework? Will flashfire be able to load it?
Also, if I were to revert back to the stock NB1 build, can I re-root and install clockworkmod (would LOKI work then?) on it and then go to a custom rom like cynogenmod or are there problems with this because I already have updated all the way to 5.0.1? (I've done this rollback through ODIN before and it's not too bad.)
I'm new to android modding so this has been a learning experience.
Thanks
Once upgraded to the locked bootloaders, there is no going back to loki. You can downgrade from 5.0.1 to 4.4.2, but you can only use safestrap recovery, and only touchwiz based firmware. Also, safestrap doesn't work on 5.0.1 yet. From what I have read, with 5.0.1 you'll have to wait and see what the developers come up with. If you care to learn more about the history of bootloaders, there is lots of info in these forums.

If xposed ever is updated to support Lollipop Touchwiz, you'll be able to flash it using Flashfire or using the Safestrap workaround (flash 4.4 kernel so you can get into safestrap, flash files, then flash 5.0 kernel). There's no way to go back to CWM or TWRP past the old MF3 4.2.2 update, which has long come and gone now.

Newbie requesting help to upgrade from 4.2.2 to Lollipop

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
