[Q] Questions about unrooting - One (M8) Q&A, Help & Troubleshooting

Hello just a few quick questions about unrooting my M8.
Will I lose the sim unlock?
What rom will I need to flash, just the latest stock rom?
I ask this as I want to use android pay and as far as I can tell there is no work around for using the app with root, Tried several methods and got nowhere.
I'd happily keep my root if there was a workaround
Kind regards!

I don't know much about android pay as I don't have that service here in my country.
If you need to unroot or flash a stock ROM, it will not remove your sim unlock..
You need to install the stock ROM that is meant for your current firmware.

Yeah, Android Pay has not been active long in the UK at all.
Ok I will give it a try later on, Thanks for the help!

How did you root? Are you on a stock ROM now? If you are on stock you can use the full unroot option in the Superuser app. If you are on a custom ROM did you take nandroid before hand? If so you can restore that. If you don't you can get one from ckpv5 thread here (if your firmware is listed)

[Q] Root after GB update

First, sorry for another 2.3 OTA question but I am getting confused reading all these threads, so I thought I would just post my question straight out: I am currently running Sinister ROM V4 and want to know if I run a RUU and then install the 2.3 update will I be able to root (using Unrevoked) again?

Just download and flash a rooted version. Don't bother taking the actual OTA update and risk not being able to root. The new bootloader that comes with the update is locked. You're better off just flashing the rooted version of the update, and eliminate any risk of not being able to get root back.
It is possible that if you remained S-off after the OTA, then you could reflash your recovery. I don't recommend that though, as a general rule of thumb, if you have any desire to root or remain rooted, then stay away from OTA's and just flash what the devs give us here.

That is the one I would flash. It's just the completely stock ROM, no modifications or anything. I would recommend doing a complete and full wipe before flashing this rom, just to make sure you get a totally clean flash.

[Q] how to unroot/flash to install sprint patches

I'm trying to revert a Sprint customers phone back to factory defaults so he can install the carrier patches and updates, is there a way to do this? would i need to unroot or just flash a stock rom?
just need to know where to start, any suggestions or advice would be greatly appreciated
Assuming it is rooted now, if you don't want it to be rooted, just flash a stock RUU, that will unroot and return you to stock. If you want it to stay rooted, just flash a stock rooted rom.

Sim Unlock Rogers S3 on CM11 M10 (4.4.4) [SOLVED]

Hi everyone,
I am looking for a way to sim unlock my S3 so my girlfriend can use it on Telus (I just got an OPO )
Before I purchase a code, I have a few questions, if anyone knows the answer
1- Will an unlock code work with my setup? (I am seeing reports of it only working on Stock 4.1 and whatnot)
2- Where is a good place to purchase a code? (Rogers a crooks with a 50$ fee and I don't wanna get ripped off online either)
Thanks!

You will need to be running a stock or close to stock ROM in order to use the unlock code. You do not need to be on stock 4.1.1 to use an unlock code. You need to be running stock 4.1.1 if you want to unlock using the free method. You may be able to unlock it using a code if you are running a stock dialler.
What bootloader or baseband is on your phone?

I managed to get a code from Rogers for half the price, which is "not that bad" I guess...
I have yet to try it as I don't have the SIM card with me atm.
Baseband: I747MVLUEMK5
it's my understanding that downgrading from this will brick your phone...
Thanks for all the info!
Yes, trying to downgrade from mk5 will brick your phone.
Find the stock Rogers ROM from sammobile.com and flash it via Odin. Flashing back to stock will wipe all user data and files so make sure you backup everything you need before flashing back to stock.

Ok I tried the code and it didn't work.
I'll read up on the Odin procedure... I've done it before on another phone but I wanna make sure I don't end up with a brick! Thanks!

ah one more thing... since I'm using the unlock code (I don't believe the free method works on Rogers phone anyway) should I flash to stock MK5?
If I go to stock MK5, eill I be able to come back to CM afterwise?
Thanks!
The free method will only work if you are running an i747 or i747m on stock 4.1.1 including the bootloader.
If you flash back to stock mk5, you should be able to re-install cwm and CM11. There are many threads on disabling knox and install CWM.

Hi! Reporting back, everything worked well flashing stock rom using this method:
http://forum.xda-developers.com/showthread.php?t=1739426
I had a slight problem after the Odin flash where I had to boot to recovery and factory reset to get out of a boot loop, but everything went fine after that.
I managed to unlocked the phone, changed the recovery using the aforementioned thread and got back up and running on CM11 M10 in no time!
Thanks a lot for your help sir =)

[Q] Is flashing back to stock and accepting OTA worht the headache?

Is returning to stock and accepting the ota any different than just flashing the new firmware that @Sneakyghost puts up? I am not using a stock rom so is there something I need from the ota? I'm still new to the custom rom world and have never had the option before.
I know it's probably a dumb question but thanks for your guidance.
If you flash my full stock, wipe package, and then TWRP and some custom ROM afterwards, you'll have pretty much the same effect. If you're S-OFF, you have no need to go back to stock.

If your S-off, just use sneakyghost's files. The ruu/ota method is only necessary if you're S-on and your provider provides an update.
sweet thanks guys. I am s-off so I will just stick with using sneakyghost's files. So much easier than having to reconfigure everything. I just flashed the 2.8 DevEd firmware about an hour ago. no complaints so far. Will use t-mobile's when they come out with their update. I have a DevEd and an AT&T Ed but they are both connected to t-mobile. Both are s-off and on custom roms. Only reason why I want to use t-mobile's firmware is to use the wifi calling feature when I travel. Thanks again!

Questions on how to go from VZW N4 LP to MM

Hope the title isn't confusing but I wanted to ask some questions and get some answers without blowing up hsbadr's thread on how to go from LP to MM. So here it goes.
When flashing the full firmware update coming from an already unlocked and rooted Verizon on LP to MM what happens?
Are you back to stock MM rom from Samsung or are you on a modified version of the MM firmware? In other words can I flash the full update and just stay on that base rom?
I believe that is the case and if so hsbadr says we can root and go through the process of unlocking again. What root works best and is it permanent or is it temporary? Is it really temperamental like on LP or will it stick easy enough to unlock?
My purpose in asking is I would like to do all this in phases and help others understand. If I flash the full firmware then I would like to stay on the base rom MM for awhile and when I have time I will unlock the phone.... Again. However if I can't have perm root then flashing the firmware would need to be done in one go with the whole unlocking process.
Any answers are very much appreciated! Thanks ??

Which full firmware? hsbadr's* is a hybrid Lollipop/Marshmallow version which I don't think would be a suitable daily driver. The full firmware from sammobile will give you Marshmallow as Verizon intended. Either way, your bootloader is locked. Using hsbadr's means your bootloader can be unlocked. The official version, not so much.
With the full official firmware being available, I would not advise using the update.zip method in other threads. Either flash the official firmware in ODIN or take the OTA update. Either way, you'll have a locked bootloader. Rumor has it that you can flash a Lollipop firmware and re-root, but I wasn't about to try. I could bide my time and let the developers work their magic.
* Also extending credit and thanks to ryanbg and beaups who together worked to get us an unlocked Marshmallow bootloader.

If you want root... if you think you'll want root... just bite the bullet and do it. Jasmine ROM has all of the benefits of the Verizon version of Marshmallow. If that's good enough, stay there. If you want to explore, that option will be available as well.
Yea I'm talking about hsbadr hybrid. I'm unlocked and rooted on LP using one of his roms right now. Just want sure what the hybrid version of MM meant. Thanks for the help and understanding. Makes sense now.
