[Q] Bootloader Unlock method(s)? - G1 Q&A, Help & Troubleshooting

I doubt this will get a reply but what's the best method for unlocking the Bootloader on the G1, HTC's official method or flashing a new Bootloader? (read it somewhere)

If you use HTCs method you will need to fastboot flash a new kernel after any ROM change, really a big pain in the butt
I would say use the tried and true methods of downgrading, exploiting, and then flash away to hearts content

Stock Unlocked Nexus One + root = voided warranty?

Hey Guys
I have bought myself a stock unlocked AT&T version of the Nexus one
It has never been rooted and I am on FRF85 at the moment (that was upgraded from EPE54b to FRF85 using the manual update method
Questions:
1. Does unlocking the bootloader mean you basically sim-unlock your phone?
2. If I have a stock unlocked phone, do I need to unlock the bootloader to root?
3. If I dont need to unlock the bootloader, when/if I decide to root my N1, will I lose warranty?
I guess question 3 is dependent on 2 above
Thanks
Unlocking the bootloader has nothing to do with sim unlocking your phone, these are two complete separate things
1 no. but I think there is no locked n1 available, so it is unlocked quite sure
2 maybe, depends on your build number. I think you have to unlock your bootloader with the att version
3 no

regarding rooting without unlocking bootloader, see the sticky in the nexus android development section
@flybyme - thanks for your reply - i had a look at the sticky thread you were talking about rooting without unlocking the bootloader.
1. what's easier? Rooting with unlocking the bootloader or without the bootloader?
2. What's more fool-proof so-to-speak?
3. What would you recommend?
Sorry for so many questions but thanks for reading
1. With unlocking the bootloader is alot simplet BUT you will loose your waranty.
2. Once either process is complete there's no real difference since you can use the custom recovery in exactly the same way to flash any further roms.
3. I would suggest _without_ unlocking the bootloader. At least give it a try, the worst that can happen is it doesnt work.

[Q] Bootloader unlock and Omnius problem

Hi
today i sim-unlocked my Xperia X8 using Omnius, but now i want to unlock the bootloader to install a different kernel from the stock kernel.
Following the instructions below http://forum.xda-developers.com/showthread.php?t=1254225, when i start the file msm7227_omniusSL.cmd i get this:

Thanks a lot
I have the same problem ...
me too...any news?
Same for me!
Any of you with original 2.1??? Maybe it only works on original 2.1, I remember that I had to change from rom to original 2.1 so I could unlock with Omnius.

Hi,
I have been making some experiences and I think that all of us want to unlock boot loader to be able to change kernel.
So it's true that using the omnius method it doesn't work but if we use semc method it works, but we loose radio.
So my idea was:
1- Unlock with SEMC method
2- Apply custom kernel
3- Unlock with Omnius method (this will relock bootloader but recover radio)
I have tried 1 and 3 and worked, I'm just affraid that also doing nº2 might bring some problems, what's your opinion?
Found my answer!-""If you relock your bootloader while using a custom kernel your phone will be bricked!""
Somebody already unlocked bootloader anyone of you?
I have searched I never found anyone that sim-unlocked with omnius and then unlocked bootloader

I just found out this myself. After wasting $100 (Sale Price) for the omnius unlocker. They never stated anywhere that it would relock bootloader, nor did they mention it could be unlocked. After an inquiry, I was told that msm7227_OmniusSL.cmd should help me...? So I am off on another research adventure. Not to mention I cannot even get my phone to "register on the network". Anyone want a Omnius License with 11months and 2weeks with 4 x10 unlock credits? I take paypal! I just knew I should have ordered the sekey and waited a month for it to arrive from hong kong. I truly feel like I got the "Royal Shaft!".
Can anyone help?
@unimatrix725 if you made a backup of your TA, then you could restore your TA as it was before you unlocked with omnius, so you can unlock your bootloader, the only downside is that your phone will be sim-locked once again, oh and watch out, because you can only restore TA with an active omnius account, i.e. have a 1 day/month/year account, so if you want to restore your TA you should do it before selling your credits
i hate that the only safe way to have both bootloader and sim unlocked is with setools, because the credits i dont mind, but the activation fee is too much price for unlocking one phone
well,for our x8 device,we can actually unlock bootloader using flashtool(latest one)
here a complete tutorial with picture that i manage to safe as pdf file(for my future use) and i think it might help,but it actually from x10 forum,however i already test it myself,and work it for our x8,to unlock the bootloader,follow this step carefully
press thanks if i help
he he he, sorry i think i misspoke that, what i meant was have unlocked sim with setools and unlock bootloader with any other method, not necessary both with setools , if someone could fix the my7227bootwrite_omniusSL so everyone that unlocked their sim with omnius could unlock the bootloader would be great, but i haven't seen any dev interested in helping us ...

OK EVERYONE HAVING THE SAME PROBLEM HERE IS HOW TO FIX IT!! After network unlocking your phone with Omnius and you then want to unlock the bootloader follow this tutorial: http://forum.xda-developers.com/showthread.php?t=1254225. You will be using tool msm7227_setool2.cmd to unlock your bootloader. When you have unlock the bootloader install a custom kernel then install your custom rom I suggest GingerDx. (I am not going to get into how to flash a custom kernel or roms there is loads of threads to help you with that). You will notice the network does not work (no coverage). Download the stock kernel from the link above. Flash the stock kernel then use msm7227_OmniusSL.cmd to lock your bootloader. This may take a few times and a bit of patience before the bootloader locks. Now you will have coverage and be able to use any sim card in your phone. Custom kernels dont work after using omnius network unlock tool. It always ends up with no coverage. So just stay on stock kernel. If you need to update your rom you will have to go through the whole method again. I have attached the bootloader unlocking/relocking tools below

[Q] Bootloader and Rooting - which one does what?

Hello,
I just got my new Xperia Z having used my ancient Iphone 1G for the last 4 years and I have no experience with Android and anything related to it what so ever. I've spent the last 2 days tirelessly working my way through various forums, guides, wikis to get an idea what I'm dealing with here and where to start, but there's an important decision that I could really use your thoughts and tips on.
After reading up on it, I decided I want to root my phone and this seems to be somehow connected to unlocking the bootloader and this is where I'm worried. I read the guide on how to unlock the bootloader and the warning about losing DRM Keys and the consequences of this scared me away from it. Now I'm left wondering, and this is my actual question here:
What is the difference between unlocking the bootloader and rooting my phone and simply rooting without unlocking the bootloader?
And in case the things I want to do are only available with an unlocked bootloader: how damaging is it to lose DRM keys and therefore the bravia engine and gracenote? What made you decided for or against unlocking the bootloader?
Thanks!
Hi,
maybe I can help you.
Bootloader is like the BIOS of a PC. It checks everything at start up.
Locked Bootloader only allows to run the Stock FW and in this case the DRM-Keys are working (everything is checked and safe)
Unlock the Bootloader means you were able to install an modified / other FW and then you loose the DRM-Keys (the manufacturer hasn´t checked the FW and it is in the eyes of an manufacturer "not safe". You will also loose your warranty.
If you unlock the bootloader Root is always possible as I know.
In this case the system is not from the manufacturer and unofficial modification could be done to the system. Normally all modified Systems have Root access. So you were able to do things that the manufacturer has normally not allowed. Modify system files or something like that. Also it could be possible to copy for example a downloaded and payed movie to another device. This is why you were not able to download a movie on the Play Store if you have root. On a locked bootloader the FW (system) does not give you the possibility to copy the movie to an other device and everything is "safe" (from the view of companies). No illegal copies are possible. (DRM-Keys)
Since some days Root is also possible on a locked bootloader.
The bootloader is checking the status (locked) .. then checking the FW (stock) ... DRM-Keys still valid.
But due to the root access you were also able to modify system files and apps can recognize that you have root access. So you can still use the bravia engine for example (DRM-Keys are ok). But the Google Play Store will still recognize that you have root and will not let you download movies.
This is my experience with Root ... If something is not correct, please correct me

Hi and thanks a lot for your reply, helped me understand the difference of both better!
If I only root but do not unlock my bootloader will I be able to do anything other than using custom firmware (ROMs)? Will I be able to install Apps that require root or install custom modification like the ones offered on this forum that need to be "flashed in recovery" if I only root not unlock my bootloader?
Also, still looking for some pros and cons (my second question in the original post).
Appreciate all your help!
root will give you access to recovery (in time - still in development) and you can install apps that require root access
custom mods - yes you can install them via recovery and some can be installed with root access and without recovery
if u unlock bootloader you will lose bravia engine not sure bout gracenote as i dont use it
you can check this thread http://forum.xda-developers.com/showthread.php?t=2154310 too see what have people wrote bout
rooting with unlocked bootloader
The main thing pointing me towards unlocking bootloader (I'm already rooted on locked bootloader) is being able to install kernels and major roms.
For example, you could flash Doomlords kernel and over clock the processor a bit, but you could also reduce power and save battery
The major roms I speak of are the ones that are kinda cross device: CyanogenMod and Paranoid Android to name 2. CM is based on pure android, no Sony changes so we can't flash that on locked bootloaders as it requires changing kernel. PA is same.
As for the downsides. I'm not too bothered about DRM keys. I use Spotify for music so don't think I need gracenote. Never watched a movie on my phone. BE2 isn't my cup of tea... Over saturates everything.
I'm going to look into DRM keys more tomorrow, but if someone can correct anything I've written then please do
Not being able to restore via Sony tools... Isn't that bad as you're going to be using flash tool a lot so you'll be used to that. Just keep a generic stick firmware .ftf around in case something goes horrendously wrong (usually recovery backup is enough I think).

Nice thread, I had this question too
It's my first android and I guess I should unlock the bootloader and then root, this way I won't have to wipe my data later when I decide to try cyanogenmod or something else?
Also what happens if sony release 4.2? Will I lose my bootloader unlock and root?

I would say root without unlock for now.
When you want to try cyanogenmod or others. Just backup everything using titanium backup and then u can restore after unlocking.
Rooting with a locked bootloader means sony are not aware your bootloader is unlocked

Thanks for all your replies, helped me out a ton!
I think Im gonna root without unlocking bootloader for now to get my feet wet and get a grasp of it's capabilities and limits. Can always restore the phone if I screw up and can always unlock bootloader later if I need it.

If you unlock Bootloader, you shouldn't update from Sony. Since you've (hypothetically) already unlocked, you already have 4.2 avaliable from FXP and if you really want the Sony Update maybe you could flash it via flash tool. Bootloader unlock will never be lost (until someone can create an explicit relock file, but customs roms won't relock it). Root maybe lost if you flash a rom without it but you should be able to get it back easy.
With locked bootloader, we have to wait for Sony to bring 4.2 as we can't access the kernel, but we retain the ability to use the official updates. If we're rooted and we update, we are no longer rooted and we may be unable to use the same exploit.

[Q] root by using exploit

Hi,
I'm looking to root my HTC One. I know the easy way is to unlock bootloader, flash recovery, flash su, done, but there is that part about "may void your warranty". I read that HTC will still repair hardware issues even if the bootloader is unlocked, but still I'm curious about different ways to root.
So... as far as I can tell by looking at the htcdev kernel source the kernel is vulnerable to the sw_perf_event exploit (http://packetstormsecurity.com/files/121616/semtex.c), and than there is this project https://github.com/android-rooting-tools/libperf_event_exploit.
I was wondering if anyone made that exploit work on the M7 (aka found the right offset) and also if you think it would be worth rooting with that. I guess I won't be able to flash new ROMs as the bootloader would still be locked, right? Or will I be able to flash the recovery partition withoud needing to unlock the bootloader (I guess not)?
Thanks

this is false. you will have to pay for any repairs performed on the device.
Blanket statements like this are troublesome. The warranty coverage varies by country. I've had warranty replaced phones that were rooted with no problem here in the US

[Q]s-off vs unlocked bootloader

What are the benefits of s-off over just unlocked boot loader
by unlocking bootloader u can root ur device, can flash custom recovery & custom roms on ur android device....

I don't have this particular device but I will tell you the general information and you can work with that.
About Bootloader(Unlocked Bootloader):
The bootloader is like a BIOS of your PC. It is the thing that is powered on and verifies all hardware and is responsible for making connection with the hardware. This can either be unlocked or locked. When you have a locked bootloader you can still root (if an exploit is available). You can even install a recovery or custom rom if an exploit is available (like BUMP was). What was it doing? Signing the images for your so the locked bootloader will think it is the OEM image. In most of the cases this is not so happy. Usually you can't flash a recovery or a custom rom or stuff like that with a locked bootloader. Some OEM's provide websites to unlock the bootloader (with the cost of losing warranty; well not really). This is the case of Sony, HTC. Some Oem's don't provide this.
About S-off:
What does S-off mean? Security off. Your device will come with S-ON always unless it's a Dev edition (correct me if I am wrong). What this does is it doesn't leave you to do very advanced operations related to the EMMC (the Nand chip). You can't flash a bootloader you wish or stuff like that. Update radio partition. In some cases system partition is also secured so you can't flash a custom ROM. By S-off you get full control of your device but if a mistakes occurs you will end up with a hard-bricked device.
Peace. Hope you understood.

Things is, i was more concerned about the practical info about this device specifically because I have read that with just bootloader unlocked, the roms that i'll be able to flash will only change the visual and not so much with the kernel etc. I don't understand why people would choose to S-OFF for this device for other than just relocking the bootloader.

yes but nth to lose on HTC except warranty (still subject to which svc ctr tho) while on Sony, losing DRM keys (w/o backup) are like downgrading ur phone full capabilities.

Not really, you can flash kernels, roms ( aosp roms etc ) with unlocked bootloader, S-off gives you other stuff like changing mid, cid, sim unlock, downgrading/upgrading bootloader, converting to full GPE or dev edition, unlocking bootloader without need of HTC, flashing splash image, custom bootloaders, even converting to Windows ( if available of course ) locking it instead of re-locking it, restoring it to full stock state ( which is not possible without S-off ), simply put your device has no limits with S-off on HTC.
Anyway S-off isn't really needed unless you care for the things above ( if Sony even has S-off ), Sony has poor development so S-off isn't even needed or unlocking bootloader since basically all you get is aosp roms, stock alike roms are flashable with locked bootloader as far as I remember.
