[Q] Does rooting void warranty? Can Nexus Root Toolkit bring warranty back?

Hi all,
I received my Nexus with 4.0.4 and after OTA update (4.1 JB) I had the following problem;
1) settings->mobile networks says (no sim)
2) *#60* says IMEI null/null
3) broadband version says 'unknown'.(device was not rooted at that time).
I tried several things to fix it by no luck at all. Could you please help me with the below questions? I searched a lot but no clear answer.
1) Does rooting void warranty? (I used Nexus Root Toolkit for rooting)
2) I used Nexus Root Toolkit to flash stock + lock the Galaxy Nexus. Can Samsung detect whether the device is rooted or not in the service? Does Nexus Root Toolkit's flash stock function wipes the data&cache and everything totally? (By the way it installed 4.1.1 as stock not 4.0.4 that I had when I received the device)
I will apreciate if you have any clear answers as I could not even use my phone for 1 day because of that official OTA update. Rooting is less risky than OTA I guess.
Thanks,

unroot, relock if you havent already, return the device.

When I press power + volume up&down bootloader menu appears. I can select to restart boot loader or recovery mode or shut dwon via that menu.
is it normal to have that on an unrooted phone? I already performed flash stock + lock operations.

This is normal as every Android phone has a recovery and a bootloader; a lot of people prefer an alternative to the stock recovery and usually will unlock a bootloader to do so and we need these things in the first place to get more creative with our devices .

Hi,
I have the same problem even I do not have a SIM Card installed on the phone.
I checked the status without a SIM Card and IMEI/Baseband still seem as UNKNOWN.

Mi Max 3/32 hardbricked after installing MIUI 7.5.11 from xiaomi.eu

I have flashed the newest MIUI developer from here from TWRP 3.1 and after I selected reboot -> system
After that my phone turned off and now I can't turn it on. My Mi Max can't go neither recovery mode nor fastboot nor EDL. It became hardbrick. No reaction after connecting to PC with any possible combination of pressed keys.
What's wrong with my Max? Can I bring my phone to life?

I hade something similar with my redmi note 3. (IF I remember correctly, only hade a blinkning red light). Check Guides for redmi note 3, its a more popular device. maybe some of this will help you: https://forum.xda-developers.com/redmi-note-3/help/hard-bricked-redmi-note-3-sd-t3360457
or google, might be info on another site, like miui.com

@Arti42000
Probably you need to remove the remains from the old Recovery (Stock).

You are going to have to open your phone up.
First download and install the Mi Flash Tool. Install it.
Second download the latest STABLE Miui fastboot rom.
http://en.miui.com/a-234.html
Untar the tarball somewhere.
Start the MiFlash tool and select the folder you untared
http://i.imgur.com/SUZWJMM.png
Open your Mi Max
http://www.ihowfix.com/xiaomi-mi-max-teardown/
Plug a good usb cable into your PC, then the other end part way but not fully into your Mi Max.
Find the two test points I circled in red in the picture, use a wire to short them. While you are doing that, have your computer ready.
Now, plug the usb cord all the way in and start clicking refresh in MiFlash
Your Mi Max should show up as id 2 device 09234f or whatever.
http://i.imgur.com/aC5S7Pt.png
Flash, and wait for the process to finish.
If your Mi Max doesn't show up, just unplug the usb cord, make sure you have those two points connected well, and replug. It's the hardest part and it can be difficult to do right.

@chriscarver
You are not allowed to unlock it officially ?
On the official forum is a form of treatment to the manufacturer to unlock the bootloader.
And what is the point in the wire, which until which the end not is inserted into, in the charging connector ?
The wire must be inserted with great speed or you'll perform the function of phase (+) current ?

It is so chaotic as the success of his operation.

No.
He hard bricked his phone during a flash.
He already has an unlocked bootloader. He is unable to get to recovery or fastboot.
In order to fix it he will have to follow the procedure I gave.

Not the fact that its bootloader is unlocked.
Recovery can be installed with locked bootloader.
The remains of the old recovery to do errors .
You must delete them manually.

You're tired... I see it... just the first time I hear about hardbricked mi max.
Maybe this moment was worded differently and I'm trying to understand.
For example, it may be the need in "Hard Reset" the device.
You don't have to repeat, it is your personal right.

I sorted mine with testpoint method.

Device need not be having unlocked bootloader to have custom recovery and rom.
OP will have to short points on motherboard to boot it into edl mode and then flash it. There is a thread for unbricking hard bricked mi max. Its explained there as well.

Need help unlocking my Note 4

Hello,
I have a Sprint Galaxy Note 4 I'd like to unlock. I called sprint and got the unlocking code. I was to wait 72 hours for the phone to be fully unlocked. Then, I needed to swap my sprint SIM with a different network SIM, and the phone would prompt me to enter the code, and that would be it. Unfortunately, I received an email with the following message:
Letting you know your CPO SAM N910 WHT SNGL on line XXXXXXXXXX cannot be
unlocked due to programming restrictions associated with phones like
yours that were manufactured before February, 2015. You can try
providing your master subsidy lock (MSL) code XXXXXX to your new
carrier to find out if it will work on their network.
Keep in mind we can't guarantee your older phone will operate correctly
on another carrier's network. Each wireless provider determines whether
or not they will utilize the MSL code to reprogram a phone for use on
their network.

I put a different SIM in my phone, boot it up, and I get an invalid SIM error, but the phone does not prompt me to enter a code.
I have read and seen multiple Note 4, including the Sprint variant, being unlocked. Does anyone know what I need to do to unlock it?
Thanks

Thanks - it's kind of hard to follow the instructions. It's unclear what he is doing.
It would appears that you first place the phone in download mode. In his instruction, he attempted to do that, but the phone rebooted. Is this a necessary step? Then he put the phone in recovery mode. But after that, he doesn't show you want happens. He simply moves on to unlocking a different phone. Is simply putting the phone in recovery mode unlock it? I doubt it... do I click on the Unlock button while in download mode to unlock it? It's not clear

Follow these steps exactly
Before you begin you must have samsung usb drivers installed in your windows pc.
1 download cdma yemen tool that i mentioned in my earlier replies.
2 put your phone in adb mode by dialing ##3424# and choose adb+dm (very important)
3 reboot device
4 open tool and connect your device via usb cable (WATCH OUT CAREFULLY FOR ANY POP UP WINDOW ON YOUR PHONE YOU MUST ALLOW PERMISSION TO CONNECT DEVICE WITH TOOL.
5 inside tool click on port/adb and select your device.
6 choose your correct model N910P of you have Note 4 sprint.
6 click UNLOCK TAB in tool and wait until your device will reboot automatically.
thats it.
After reboot hopefully you have permanently unlocked device.
If your device successfully unlocked then dial ##3424# and select mtp+adb back to normal.
The guy is showing in video all the stuff that this tool can do so dont go to download mode or recovery or anything because that's for removing frp lock and other stuff.
Let me know if it worked for you.
By the way if you are on latest QI5 firmware i am not 100% sure this tool will work because QI5 has latest bootloader/modem and it's not easy to unlock.
If this tool did not work for you let me know i have workaround.
Good luck

I am on QI5, and I didn't see a adb+dm option. I did see a DM + MODEM + ADM option under QUALCOMM USB SETTING (see attached screenshot), so I selected that.
The tool says Unlock Done With out Root... but it doesn't appear that the phone was indeed unlocked.
What's the workaround you have?

Yes DM+MODEM+ADM i was meaning.
The workaround i have is you have to flash Twrp RECOVERY and have to flash "ENG ROM" DONT FLASH ENG BOOTLOADER OR BASEBAND YOU WILL END UP UNKNOWN BASEBAND AND NULL IMEI.
Flash the rom from twrp and Also you have to flash supersu.zip to get full root with eng rom.
after that you have to use tool "Z3X SAMSUNG TOOLS PRO v27 or higher"
I cant share links here on xda for z3x because its heavily paid tool but if you search on youtube "z3x pro cracked" you will get 100s of videos with links to download.
HERE IS THE LINK FOR ENG ROM BY @freeza thanks to him.
https://forum.xda-developers.com/no...leakmm-sm-n910p-touchwiz-marshmallow-t3327350
After flashing eng rom the rom will take 35 minutes to boot so be patient and wait and also make sure battery is fully charged.
After that enable DM+MODEM+ADM as i mentioned earlier and you can unlock from z3x domestic use for american sim or unlock for international sim use.
Once phone is unlocked you must have to flash QI5 stock firmware via odin and do factory reset from stock recovery and dont worry the unlocking will stick permanently.
I personally did this method on QI5 ON my own device and it worked just fine.
I REPEAT DO NOT FLASH ENG BOOTLOADER OR MODEM OTHERWISE YOU WILL SCREW YOUR DEVICE COMPLETELY.
Cant explain more you got the idea i guess...
Good luck.

Btw try first the cdma yemen tool to.unlock with this rom with root. Maybe it can work.

It appears that I am not able to install TWRP... I install it via Odin from AP, and the install is successful. But when I try to boot into recovery, I get the stock recovery....
I tried TWRP 3.1.1 and 3.2.3... same thing. What am I not doing?

Open odin and uncheck auto reboot in odin options
Choose AP and flash twrp
After Odin shows pass remove battery
Insert battery and Boot straight into twrp by volume up+home+ power
If your phone reboots after flashing twrp the system overwrites the stock recovery over twrp thats why you are losing twrp so do not reboot system after flashing twrp.
Once you booted into twrp then if will stick permanently and stock recovery will never show up.
If i was helpful then consider hit thumbs up on my replies.

Thanks! It took a while with multiple flashes, but I think it is fully unlocked now. I am able to put a Verizon SIM card in it and get no sim card error message.

Usure if anyone still using this. But I just got my phone unlocc using it on crikket/att. Unsure why you got a 7 wait but I was able to make phones and use internet immediately after I unlocc the phone. The only problem I'm facing is being able to use 4g o the phone.

You won't get 4g/lte because n910p sprint note 4 is CDMA model and you need GSM model for 4g on at&t/cricket.

What's wrong with you!?
Where are you, xda senior

Have you checked that an update is available first?
I'm on September and no updates have been released yet. Same baseband as you.

Why do you want to unlock your bootloader? Checking that OEM unlocking box in the Developer settings doesn't unlock your bootloader.
Flashing anything on the phone will trip Knox and Void your warranty as well as prevent you from receiving updates including the Android 10 update coming this April. Your phone didn't stop receiving updates, it's just not available where you live yet. Just like waiting for replies to your post, you're impatient to get a security update that won't make much difference to your phone. My phone is on the November patch even though it's January and I couldn't care less, because I'm patient you should give that a try

I’m really grateful, thank you for responding to my topic
I Unlock bootloader in this manner
Step 1 – Allow bootloader unlocking in Developer options > enableOEM unlocking.
Step 2 – Power off your device. Press Volume Up + Volume Down and plug in your device to a PC to boot into download mode.
Step 3– Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
Then I locked it again in the same manner.
I don’t know yet if the bootloader is locked or unlocked
and how to fix this : Block-Based OTA
So... have I broken my phone?
I need help
God bless you....

Thanks a lot

The other user mentioned that official firmware through Odin wouldn't trip knox which is something I've read before but wasn't sure. In any case, I forgot to mention that if you live somewhere in the European Union, a tripped knox shouldn't void your warranty. If you want to flash with Odin I do think you need to have the bootloader unlocked, but I'm not sure how you would do that.

It's time for me to end your ignorance (im looking arrogant right )
first of all you dont need to unlock your bootloader to install official firmware.
-the Reboot Recovery Cause is ((bootchecker) rebootRecoverywithkey)#
blocked-based OTA
Supported API : 3
MANUAL MOD v1.0.0# is not an error
-Block based means what it means and OTA means Over The Air.
-manual mode if just stock recovery.
-flashing latest official firmware wont trip knox/void anything.
-it's completely 'normal' that you don't have latest update if you live in an area where providers (like algeria) don't give a damn about you.
here is the firmware you should flash in order to get latest update faster than any others countries: https://samfrew.com/download/Galaxy__A70__/to3j/SEK/A705FNXXU5ASL4/A705FNOXM5ATA1/
