[Q]clockworkmod flash and zips

Just to confirm one thing before i go smoke my NS's warranty away. If i nand backup the current stock rom and then flash the custom roms...i can always easily flash back to stock rom no?

Yes it is pretty easy to restore to your current build from a backup
Also, there are threads with stock images for the different models of the Nexus S here on XDA detailing how to go back to stock if that's something you choose to do so later

but wouldn't just recovering to backup takes to stock rom? and i believe the root can be deleted right? so that if i plan to send back the phone, i can do that...i'm only flashing roms over the weekend so that i can see if the wifi problem is fixed with different kernels...
I can't get my router to be shown in the network list and other networks have poor wifi signals :/ i'm really worried...

Yes recovering from your backup will return you to a rooted stock, and you can remove root by deleting su from /system/xbin/

can you direct me to clockworkmod apk? since i don't want to flash the .img

The recovery image isn't an .apk file, you are going to have to flash the .img from fastboot to get clockwork recovery installed.

yes i know it's not an apk but i believe, clockwork can be installed as apk and then rebooted into the clockwork recovery through the application as my motorola defy...
i don't want to flash the .img file or i won't be able to remove it if i had to...

You can flash a recovery image from ROM Manger which will install a custom reocovery
**However**
ROM Manager needs root access to install a recovery image, so therefor you need to install root permission, which in turn requires a custom recovery to flash the zip file to install the necessary file.
So... flashing the recovery image from fastboot is a necessary step in rooting on this phone

so apps like z4root and universal root don't work for nexus s?

I'm honestly not sure what exploits work with the Nexus S personally, feel free to browse through the guides that are stickied
In my opinion if you already had the intention of unlocking the bootloader, then you'll already have fastboot setup and you will already be in the bootloader so it's just one additional command to type to get your recovery image installed, pretty easy
Since the Nexus S comes with a bootloader that can be unlocked I don't think anyone would look for an expoit that works specifically for this phone because, but exploits that were built for other phones may work on this one, again you would have to browse around to see, I'm not sure about this

my main purpose is to have an option to revert back the phone to its orignal state...unlocking bootloader would be permanent no? also if i flash clockwork, that would be permanent or is there an easy way (excluding ADB) to delete clockwork ?

This phone has an unlockable bootloader. You don't need exploits like that. Just follow the directions on this forum for your specific model and you will be fine. Everything you will do can be reversed. So don't worry.

read my previous post...unlocking bootloader will be permanent thus messing up with my warranty.

You can lock the bootloader on this phone, just use the following command in fastboot
fastboot oem lock
You would have to flash over the original recovery image from fastboot before relocking the bootloader
This phone can be returned to complete stock fairly easily, if you were to find all stock images for your particular model of the Nexus S you could completely return it to stock from fastboot with a few easy commands
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
Just look through root/unroot guides and find the images for your model, you will need to do this to at least get the recovery image for when you decide to return to stock

sorry i'm not with you here...so you're suggesting me to unlock my bootloader, flash rom? so for these purposes i won't have to install root? so how can i backup my current rom?
haha also i can't install ADB drivers :/ although i can access the phone memory lol

Yes, if you want to install custom ROM's then you should unlock your bootloader and install a custom recovery, these are both reversible.
To help getting adb/fastboot drivers you can get PDAnet from:
http://junefabrics.com/android/index.php
Setting up PDAnet usually fixes the driver problem, you can uninstall it once it's done
I think you should read through an root/unroot guide pertaining to your model, sounds like that would answer a lot of concerns and doubts
But mainly since you are concerned about your warranty, unlocking the bootloader and rooting your phone is completely reversible.

I don't think you get it. Nexus S is a development phone and comes with a factory built-in unlocker. This means you do NOT void your warranty when unlocking or rooting.
It is however recommended that you return to stock and lock the bootloader before returning the phone for any warranty needs because most idiots at sprint stores or service centers don't know any better even though the rules clearly tell them they must service the Nexus S even if rooted.
Now, to answer your question, when you restore back to stock and close bootloader the phone is indistinguishable from factory settings and data. So no, the bootloader unlocking is NOT permanent.
On a side note, you will have to use the Samsung exe to restore your phone to factory settings along with locking the bootloader if you want the original recovery. But I think there is an img of the original available somewhere.
Also, to replace the recovery you MUST use adb. There is a one click to do that but all it does is do all the steps you would do manually and still needs all drivers installed.

It clearly states while unlocking your bootloader that by doing so your warranty is voided.
While Sprint's policy is to in fact service unlocked/rooted phones this is not the case for all carrier's.
Returning or attempting to return a phone that is unlocked can very well have you turned away since your warranty is voided in many cases, especially depending on the carrier of the phone.

When I unlocked my phone the first time I had NO such disclaimer. This was something added later with an update. Therefore I did not void my warranty and anyone else can argue the same.

I'm pretty sure that the screen has always had the warranty information on it after you type "fastboot oem unlock" in fastboot and then you have to acknowledge the unlock on the phone. It was part of the original Nexus One unlock screen and I'm sure part of the unlock on Nexus S. Especially if you're on the NS4G which came out months after the original NS. I know I had to acknowledge it when I unlocked mine. It only makes sense that if you willingly unlock your device and flash something you shouldn't in example a radio for a different model and brick your device the manufacturer isn't responsible for your mistake.

Possible Brick after attempting to install Xposed

Some back story. My N5 was stock/rooted, with stock recovery. I had installed the beta Xposed framework, using this post as a guide. Following the install, during the reboot, my phone never restarted. Since then it has not been able to turn on.
Things I have tried:
I have done method 1 & 2 of this guide
I am able to lock and unlock the bootloader, it is currently locked.
I have tried the command fastboot -w
I am unable to perform a factory reset, it hangs at /data
If there is any ideas as to what I should do next, please don't hesitate to let me know.
If I am able to get the Tamper Flag reset, then my plan is to look into the RMA option.
Also, I have been following this thread for info.

So earlier when i did this, the phone would freeze. Now it went through with it, and is now showing the animated android images, with a moving bar at the bottom. It has been there for about 4 minutes now.

Same thing as before. All of the erase commands get processed, but when it gets the the system.img it fails to write it.

I think you've done her in. Can you get into recovery? You might be able to push the tamper zip and then run it in recovery.

I am able to access recovery. This is exactly what I am trying to do at the moment, but now I cannot adb sideload the zip. For some reason the N5 is not being recognized by windows.

yes, many times

So this is just a shot in the dark, but the fastboot command screenshot you posted, you had the command "fastboot flash bootloader."
I haven't read the articles you're using, but is there a reason you're flashing a bootloader after unlocking it? Wouldn't that just lock the bootloader again?
I'd start fastboot oem unlock, fastboot flash recovery, and then adb sideload the .zip you are using once you're in recovery.
Good luck.

I am just following the guide for How to return to stock. But to answer your question, no it does not re-lock the bootloader.

Here is some additional information. When I perform a factory reset in recovery it freezes while formatting /data. And when flashing the stock images, I am able to flash everything successfully except for the system.img

Reset Tamper Flag

I RMA'd my device and need to reset the tamper flag. I followed the instructions here in the forums, but it is not working. I've tried 2 different methods.
1) Download the flashable zip file and use fast boot to boot into TWRP. The problem with this is that once i boot into TWRP, it does not recognize any files in the sdcard/downloads folder.
2) Download boot unlocker from the playstore. I need an unlocked and rooted device so this seems pointless as I will need to unlock and relock my boot loader to use this.
Someone please help.

I followed that video and it did not work. First off, I can't find that zip file anywhere. The link on the xda forums doesn't give me the correct file. Second, I have a mac. For me to boot into TWRP using fast boot, it required the boot loader to be unlocked. If I unlock the boot loader to boot into TWRP via fast boot, TWRP doesn't recognize any files in the downloads folder.

Bro,
1. Flash the factory image in fastboot
2. Download the latest TWRP recovery and rename it to twrp.img and put it in the fastboot folder and download this zip http://forum.xda-developers.com/attachment.php?attachmentid=2467503&d=1387666907 and put it on the phone`s sdcard.
3. Go into bootloader mode and flash the downloaded zip in recovery, just type in cmd: `fastboot boot twrp.img` and you`ll boot into twrp recovery.
4. Done, you`re device is locked and the tampered flag is reset.
Oeps saw you have a Mac so look here:

Wrong order bro, and why would you have to reroot to flash twtp as long as the bootloader is unlocked. Once the bootloader is locked you can`t flash the image anymore

Because you need root to run BootUnlocker in order to reset the tamper flag. Resetting the tamper flag is the first thing you should do, relocking the bootloader is the last.

Yep it does. With BootUnlocker, you don't even need the script, and you can lock/unlock the bootloader any time without wiping your data and you can also reset the tamper flag.

Yes, I get that.. If I end up in a bootloop I would need to use fastboot which will erase all my data.. That's what you're warning me about, right?
To tell you the truth, I'm actually worried about this eMMC failure thing as I have a 1 year LG warranty (not google's). I have seen a few threads where they weren't able to relock their bootloaders before sending it in as the eMMC's write function was screwed up. If I send my device in with a unlocked bootloader, warranty will go down the drain for sure. LG is very strict regarding this matter.
May be I'm thinking too much but my friend had faced similar issues with his HTC One and he had to shell out half the price of the phone to get the mobo replaced even though he had warranty

I'm guessing that if your emmc failed you wouldn't be able to lock using this app. Boot it is an easy way to keep it locked until you need to unlock. It is a good app and it's been on my phone for months. But I usually keep it unlocked

you can have a custom recovery and use that app to lock and unlock your bootloader, just as you can have a custom recovery and lock/unlock your bootloader with the fastboot command.. fastboot oem lock(fastboot oem unlock).

Are you sure? If you oem lock and then oem unlock I think it wipes it each time.

Wooaaahh?! Thanks for the clarification... Just curious though, why does it not wipe everything when I unlock it the 2nd time? is it because the tamper flag is set to "true"? How does the bootloader determine that it's being unlocked the second time?
Thanks a lot!

As an fyi, I locked with bootunlocker once and then messed up by device where I had to use fastboot commands. It does wipe if you have to fastboot unlock the device again

[Q] Root in the past - Warranty

Hi guys,
I have a question for u. If I have rooted my N5 in the past and now I went back to stock, is it possible to check it?
And is it a reason to cancel my warranty?

If you returned to stock properly, no it cannot be traced.
Google won't reject warranty by apparently LG might

Did you reset the tamper flag? That's the only way Google/LG would know you modded.

How

Is it a way to reset temper flag without working screen? I watched this video - How to Unbrick or Unroot the Nexus 5 (incl. Tamper Flag Reset) on YT and I can't flash cwm-Nexus.BootUnlocker.zip because I don't have working screen and TWRP isn't help for me. Is there any other way to install cwm-Nexus.BootUnlocker.zip without TWRP?

If you're rooted and you have a video out, you can use BootUnlocker from play

I am not rooted, but I can get root via NRT. But I don't want to unlock my bootloader, only to reset temper flag.

OK, I know now, but I didn't in the past.
Will it work if I simply flash cwm-Nexus.BootUnlock.zip via fastboot using "fastboot flash cwm-Nexus.BootUnlock.zip"?

No. You cannot fastboot flash zips. You can either have root and use an application to do it, or you can have a custom recovery and flash a zip. These are the only 2 ways and both involve you needing video/ screen to do it. If it is not done, there is nothing you can do.

Thanks guys. You're awesome!
I hope LG won't check Temper flag. Rest of my phone is stock.

One more question. If I've flashed all stock files, my recovery is stock too? There was recovery.img file, but I want to be sure. And if not - Does the custom recovery void warranty?

Yes it does.
