[Q] rooting/flashing without void warranty - Nexus S Q&A, Help & Troubleshooting

Hi All,
I`ve just purchased a NS and I want it to be rooted. It was quite easy on my previous phone (SG3), but now I`m unable to find any guides to do this without unlocking the bootloader.
Actually flashing a custom ROM, such as CM7 would be the next step but I can live with this original one(2.3.4), but rooting is vital, I`m unable to live without eg. titanium backup, but also need the 2 years warranty...
Do you have any idea for solving this?
Thanks in advance.

You can try the Gingerbreak exploit. Other than that I know of no way without unlocking the bootloader.

I`v tried Gingerbreak yesterday but unfortunately it`s not working.
Any other idea?

No. I thought the Gingerbreak exploit might have been fixed in 2.3.4 but I wasn't sure. I don't know of any other way without unlocking the bootloader.

Why don't you unlock the bootloader? It is not like the nexus one. The bootloader can be locked again at ur wish with the command : fastboot OEM lock
You can unlock the bootloader, flash your recovery, flash your rom and lock it up again if that is your wish.

This would be fine if this is not causing warranty issues.
To be honest I've read somewhere in this forum that unlocking the bootloader is irreversible and voids the warranty.
So please repose me.

None that I'd know of, maybe someone got a private hardware approach/mod, but that I highly doubt.
Gingerbreak before 2.2 (I think) or unlocking bootloader via fastboot oem unlock.

This really shouldn't be a huge concern.
Look at the language on the unlock screen. Unlike the Nexus One which stated unlocking voids the warranty the Nexus S language has been tweaked to indicate unlocking *may* void your warranty.
Even with unlocked bootloaders HTC honored the warranty on the Nexus One for hardware issues. Don't expect to unlock, root, leave the LED on high for 20 minutes and then try to send it in for repair when it burns out though.

[Q] Phone vibrations stopped working.

Hi guys,
I know that this is a problem among other phones and I tried the trick where I hit the phone softly against the table or my hand. The vibrating comes back on briefly but then it goes away again. Anyone know:
1) Any other solutions? I'm pretty sure the internal vibrator is broken.
2) If warranty covers this? And if it does, can people give me direction to unroot my phone that so my warranty isn't voided?
Thanks
Unlocking the bootloader pretty much voided the warranty.
Depends on who check your phone, I know with the Nexus 1, HTC was doing repair work on hardware
problems even with an unlock bl.
To answer your question, relock the bootloader and run the RUU

HTC will honor the warranty a lot of times if its strictly hardware related.

Yes it will say "relocked" instead of "locked". Like mentioned already, HTC is pretty good at warranty when it's hardware problem.
And there's no way to get rid of that at all? :/
And Tmobile also doesn't check the bootloader and whatnot when doing this?

Can I root the Moto G3 with an app like KingRoot?

Hi peps,
I just switched from my crappy HTC One X to my new Moto G3 and I'm in love!
I don't really want a custom ROM, but I'd like to undervolt this babe. But since a root requires unlocking the bootloader = voiding the manufacturers warranty, I don't really wanna do that..
I've bought it over Amazon and I live in the EU, so I technically still have the retailer's warranty and Amazon would replace it without a hassle, but yeah.. it's new and all.
But I know there are apps like towelroot, KingRoot and what not, do they work with the Moto G3? I'm on 5.1.1.

Being a smartass is kind of my thing.
You're afraid to unlock your device's bootloader because you'll lose the warranty, but you're perfectly fine with risking the security of your device by rooting it, right? Seems odd to me, but whatever.
Generally speaking, both KingRoot and TowelRoot are used on devices where using those two methods are the only way to root those devices.
Unlocking the bootloader will have no ill effect on your device other than voiding the warranty, and, if you're worried about voiding your warranty, you shouldn't be trying to modify your device.

Who said I'm afraid of unlocking the bootloader? Who said I never unlocked the bootloader of other phones before?
I just don't wanna lose my warranty in the first two or three months, in case my phone breaks unexpectedly, I also don't plan on using custom roms, I just want the root features so I can undervolt like I said and IF I could root it permanently without unlocking the bootloader, why not?
I'm not worried, it would just be convenient to have root without losing the warranty, that's it.
As far as I know you may be able to do it search kingroot in Google then download the apk and install it then open in and follow the instructions

If you want the best of both worlds (root & warranty), then go buy a Nexus. Motorola drew a line in the sand as to what they will support, while still empowering owners with the option to unlock the bootloader.

Towelroot is exploiting a bug in the Linux Kernel in order to root a device. This bug was already fixed in June 2014.
On all Kernels with a later build date Towelroot will most likely not work.
For sure it will not work on the Moto G3 with a kernel build date more than one year after this bug was fixed.
Thanks!

It's probably been answered already but those exploits are security flaws with the SE Linux system and so with each release of android these have been patched, by 5.1 these security holes have been fixed and now by locking the bootloader
It's like just locking down and modifications to the system partition so unfortunately you can't root without unlocking, unless you have android versions lower down

What version of TWRP did you use coz I know there were some bugs on the moto range with TWRP 2.X.
I would completely wipe device using stock recovery, including dalvic/cache/data everything just to be on the safe side, then download the TWRP zip to your computer and flash it on using ADB.
Boot up normally and move the superSU zip from the link to your phones internal storage. Then reboot to TWRP, select install and pick the zip file.
superSU.zip:
http://dl-1.va.us.xda-developers.com/3/6/5/5/4/0/1/BETA-SuperSU-v2.62-3-20151211162651.zip?key=u0OeGV4-4s02KJXqrXJ-gg&ts=1466705675

Perhaps you can offer wisdom on this? I rooted my Moto G 3rd Gen once, wrecked something and had to go back to factory, then try to reroot again. Problem. No matter what I do in setting the device back to factory, the bootloader stays unlocked and reads the system software as "modified" which then seems to bork installing SuperSU. I install SuperSU via twrp and it goes fine, no errors, but when I reboot the system is lost in a loop of the "bootloader unlocked" screen.
So I cannot RE-lock the bootloader (ala setting the phone back to true factory) and after I flash SuperSU the phone refuses to successfully bootup.
Any aid? Ideas?
I had failed to backup my phone the first time with twrp and so to set to factory I downloaded the stock retail xml.zip for my phone and reflashed the entire thing via fastboot. Reinstall twrp, and try to root and the endless boot loop begins.
So I came to this thread to look into the possibility rooting my phone via another means that MIGHT work.

How to unlock bootloader again on stock 6.0.1

hi guy i already unlock bootloader previously and installed many rom but later i fastboot flashed MM6.0.1 stock and locked the bootloader and it show status :2 , now i want to unlock the bootloader again and want to install twrp and roor the device on stock mm 6.0.1 pls help
The process to unlock again is identical as the first time, if you still have the code you can still use the same one or go through Moto's website to get it again.
Note that some users have stated that if they unlock, then re-lock, unlocking again doesn't work (it worked fine for me though)... And I think one user had an issue where it bricked trying to unlock again but I could be foggy on that one.

How to set "locked" again the bootloader after unlock?

Hi guys, I've unlocked the bootloader, then I tried to lock it again, but now BL is set on "RELOCKED" and not on "LOCKED".
So, I think, in case I've to send my phone in warranty, I will have problems!
So, the question is: how can I set again in "LOCKED" the bootloader?
Thank you so much!
Did you not use the unlock code provided by Huawei? Otherwise, they already know you voided the warranty.

There is no way if you did it with the 16 digit code. It will be only relock and no lock. Had you used the other way of unlocking, you may have locked it again. Whats the requirements, only to regain warranty?

There isn't at least for now. And in any case until there is s-off even if there was other way it will show as relocked and modified after you lock it again.
there's no sunshine in the sky for now, but warranty is not voided in most countries/cases anyway.

I got the same response from HTC Czech Republic: unlocking the bootloader would instantly void my warranty, plus they said that warranty-keeping bootloader unlock is possible only in that one special case for US customers, the rest of the world voids their warranty by doing so :/
Rant on the side: I truly despise not being allowed to get root privileges without voiding the warranty - it is MY device, yet I can't control the system. I want to do MY own backups, control (or inspect) the data apps save to MY phone, and control the configuration of MY system. I really hate being locked out from even such basic configurations as the hosts file is - I'm effectively barred from some aspects of web development so that advertisements can be shoved down my throat

Right now it's only with the 175 USD XTC2Clip with all the attachments including the power adapter - and as of my last look, it cannot factory lock the bootloader thanks to temporary S-OFF so it will show up as relocked which will void the warranty anyway. In other words, we are all out of luck for now.
And it remains to be seen if HTC actually lets us keep our warranty in the US... The warranty in the box says otherwise.

175.00, S-off is not that important. Like you said a relocked bootloader voids your warranty. Why are people bothering to relock bootloader especially the OP to run the RUU, it is not needed. You do mention XTC2Clip a lot in these threads. You holding stock in the company? lol

Hell no, I have no interest in dropping another 175 bucks, I think it's ridiculous but it is currently the only way to do a number of things with the device. I'd consider it if being able to unlock and relock the phone without HTC ever having a clue was a big deal or there was a Google edition and I needed to change the CID and MID or other things but honestly, I still have my 10 if I really need to get at something that was on that phone but not on this one (for example my Battle.net authenticator). I suppose I could always try Helium though with my desktop but I imagine that's a protected app like Google Authenticator which required root to backup and why I switched to Authy.
I mentioned the XTC2Clip because it is the only way to get S-OFF of any kind right now and to point out that even with its temp S-OFF, it still can't restore the bootloader to factory locked status. It's an important thing to point out, not everyone knows that HTC has two different locked statuses, one that proves the phone has been tampered with, and one that is factory locked. A lot of people ask to go back to stock so they can send it in for a warranty claim or a refund to go buy another device. The relocked bootloader obviously kills one or both options depending on the situation.

Does it void warranty? I returned my bootloader relocked U11 to HTC due to a scratch on the display. Was offered a refund or exchange. I had to go the refund route to swap colours ( I went from Black to Blue). Was accepted without any fuss.

Yeah, a lot of people are claiming unlocked bootloader voids warranty now, however US is more relaxed. Every single HTC phone I had was returned with Unlocked Bootloader and S-off, never had a problem. Other countries are more strict I guess. I can understand not knowing the return policy and people relock for that reason(for returns) but I see many relocking for flashing RUU or firmware. This is not needed or even should be done. I'm a RUU flasher with each update, so I know no problems arise. This has been the case for the last 8,9 or 10 phones lol.
