Re-unlock - Nexus S Q&A, Help & Troubleshooting

I got a unlocked and rooted Nexus S. If for sercurity reasons i'll do a re-lock. Suppose i get my phone lost or stolen, the thief/person wont be able to flash any rom on that, since its locked. But if him do a re-unlock, i would get my data erased? Including my google account and security apps like Lookout, Prey, etc?
Thank you!

Yes - unlocking again will wipe again.

Wow... so we have no advantage on re-locking bootloader, isnt is? When it is locked, people will be able to flash over it but i think if someone have know-how to flash, probally they should know how to unlock too! And unlock seems easier than flash! Agree?

if you want to keep your data safer, re-locking bootloader will be better.
if you did not, someone can get your phone and refresh a rom, will get anything in your sd-card.

Will Gsm unlock remian intact after upgrade to ICS?

so I am using ATT Skyrocket outside USA. The previous owner somehow unlocked it and then sold it to me. The phone is currently running on Gingerbread and I am planning an upgrade to ICS (i know how to do this). What I want to know is that after upgrade will the sim lock be reverted or my phone will remain sim unlocked after update?
please consider that it will be difficult for me to buy an unlock code so please answer only if u have tried or some expert knowledge.
thank you
I had my phone unlocked by kachman from this forum by a usb hack as he clamined. It stays unlocked no matter what rom you flash or upgrade. Also from cellunlocker.net, they claim if you unlock your phone using their code, you phone will stay unlocked regardless of what system you flash. It's hard to say if your phone will remain unlocked given the little info you provided. I'd say just stick with gb until you could get it unlocked again if you need to.
Your phone SHOULD remain unlocked. An OS upgrade should not affect that, or else everyone who gets their phone unlocked would have to bring it in/get a new code every time they did an upgrade, which doesn't make much sense. I Mean I can't say this with 100% certainty but I'd be a considerable amount of money that this is the case.
unlocking is permanent ....

will there were four parties involved in the middle before i got hold of the phone but when it came to me it was already unlocked and ready to take in any sim...now the point is that since its unlocked is it possible to find out how was it actually unlocked? and if it was done through an unlock code, is it possible to extract it from the phone itself? (some one has already payed for unlocking it so now there seems to be no point of keeping the unlock code in a secret location)

is it possible to find out how was it actually unlocked? --No.
if it was done through an unlock code, is it possible to extract it from the phone itself? -- No.
is there any proof of what you say? -- The unlock code and unlock state are stored in an encrypted file system partition (mmcblk0p18) that is accessible only by the radio and completely separate from the kernel, radio, system, data, and cache partitions that are typically overwritten during a ROM install/upgrade. So, yes a SIM unlock is permanent.

[Q] Should I root and/or lock my bootloader

I have a nexus 5. The bootloader is unlocked. It has stock OTA lollipop.
I have a few questions about this device. I have read this device is special in that unlocking the bootloader does not wipe the phone. Is that true? My impression is that locking the bootloader does NOT wipe the device (true for many device), correct?
My dilemma is this. I have read it is good to have a locked bootloader, but I don't want to then later unlock it if it wipes my device. I could root and lock, but I think I lose root when the next OTA update comes. I will hence be in locked without root state.
Anyway, my question is, do I need to lock it? Should I root it first? What do I do when I lose root next OTA and the bootloader is locked? This isn't a problem if unlocking the loader doesn't wipe the device.

Unlocking the bootloader will wipe your device, unless you're rooted and use bootunlocker. Personally I leave my bootloader unlocked. You do loose some security though by doing this

I guess it would help to know the security risks.
I only install apps from the play store, and usually only ones with a huge amount of traffic.

The security risk is if you lost your phone or it's stolen. With an unlocked bootloader it's easier to get to the contents of your phone. But if you don't use a pin or pattern lock it wouldn't make a difference.

[Q] I want to get my hotspot enabled, so do I need to root to do this?

Hey all, just got my pixel. Wanna stay on stock, but maybe root? I want to get my hotspot enabled, so do I need to root to do this? I'm on sprint. Any guidance! Thank you!
If you don't or can't get hotspot enable you may have to root to get it. Plenty of info on how.
FYI
Since you are on Sprint I'm going to guess you bought directly from Google. To my knowledge you can disregard any convos about updates locking you down. That only seems to affect devices bought through Verizon.

Yes sprint and bought directly from play store.

Problem is, I already updated via OTA to latest version. Am I screwed?
Screwed?? If you mean BL locked, no. I have the Verizon branded variant but unlocked, rooted, and flashed SU. When I saw NMF26Q was available from Google I downloaded it, installed via flash-all from fastboot, then rerooted and flashed SU again no problem.

Please look at OP install instructions in this thread.
Please look at OP install instruction in TWRP thread.
I guess you aren't on Telus in Canada or your hotspot would work. When you give no information, too hard to help. But I read this forum so even though I don't have Sprint or Verizon as my provider, I know there are many threads about turning hotspot on for unlimited data plans. Guidance: read those threads too!
Then ask for specific guidance. I don't want to reread for 25 min to find and copy and paste to spoonfeed when you should read. Much nicer to fill in a few missing spots than hold your hand not having a clue of your technical knowledge and skills.
Happy holidays.
Specific guidance: update SDK tools before you start!

so I managed to unlock and run the fastboot command to push SuperSU to my new pixel. All seems good so far...but when I restart my device I get a "your device software cant be checked for corruption" message. What is that all about? Assuming from unlocking the bootloader. Is this permanent? or can I now relock bootloader since I'm rooted?

It just means your bootloader is unlocked and isn't anything to be worried about. As long as your bootloader is unlocked it will show.

Do not relock your bootloader unless you are fully 100% stock or you run the risk of bricking your phone

That makes sense. Ya havnt used a ROM or anything, do not plan on it. So for now I'm stock. So I can relock it though, get rid of that message but still maintain SuperSU/root right?
My only goal is to get hotspot working (sprint)

If you're rooted and have done the tether hack you're no longer stock. Don't lock the bootloader unless you are COMPLETELY stock.

If so, I have not done any tether hack yet....still reading since there are multiple ways to do it. (sprint variant/google play store)

No, having SuperSU means you are no longer stock. You need all stock images to lock bootloader.
If you need a locked bootloader for Android Pay or some other apps. Install one of the customer kernels, they hide it. You still need to remove SuperSU though. From what I've seen its a bit harder to hide that for now. So you can root, make change for hotspot and remove root.
Otherwise nothing hurts to have your bootloader unlocked. It gives you more options if anything ever goes wrong. You need unlocked bootloader to even load Google factory images.
PS. I'd recommend Franco kernel as it imporoves battery life.

No you don't have to root to have hotspot enabled, it's a build-in function. Simply set it up in “wireless & networks” and you are ready to go:laugh:

Depending on his plan, he may not have that option. Many do not, hence still need the tether hack.

unlocked bootloader for twrp?

Hi guys,
first of all, thank you all for your amazing work! Its great to have such nice guys working on android.
I saw a thead in the "rom" section but since im new in the forum i cant ask in the thread there :/
Do i need to unlock the bootloader in order to flash twrp for full root?
What about the OTA updates? I guess i cant updates after i unlocked the bootloader?
I read about the funkyhuwei method but it seems to be quite costly. One time or maybe even per month ok but 1 credit for 10$?? Wow..
Thanks guys!
Yes. You need unlock bootloader to do other things like flashing twrp.
And you can receive ota updates.

Hi, I unlocked my bootloader, but every time I boot I see these messages that my phone has been unlocked and can't be trusted. I understand this is normal, but is there any way to NOT see this warning?
Also, does this affect any encryption, AndroidPay, fingerprint phone lock, security setting,.... basically, what does that mean "phone cannot be trusted"?

It can't be removed without locking bootloader again.
Not until someone figures out how to flash TWRP without unlocking bootloader, OR flash official firmware but keep recovery untouched.
And it doesn't affect them (afaik anyway, it works great with Magisk and I don't think it hides unlocked bootloader).

Google Pixel Verizon bootloop, Lock bootloader

I lock bootloader on Verizon Google Pixel when my device have TWRP and i have brick! Device Loading up to logo Google on 1 sec and reboot. Fastboot work, but i don't unlock bootloader. In recovery is don't enter. Please help me!

Put the phone in fastboot mode, then run `fastboot flashing unlock` from a PC. If it says unlocking not allowed, you're out of luck, it's a brick now. Never lock your phone without being 100% stock on both slots

No idea. I've never relocked unless I am completely stock and take at least one ota first to make sure, along with full factory resets before and after updating.
There are others here that claim they where able to unlock again and save their phones though so maybe it's possible.
