Hello,
is it possible to relock bootloader after ulocking it? I need it due to the warranty.
in short, No. please search the forum for details, as this is discussed.
i suggest you just try the luck sending the phone in and not mention anythong about the bootloader. of course should flash to stock rom if that still can be done

Why you want the warranty? Want to sell it later? Or did it already got any fault?

I think, he did not say he is sending to service center. He just said he needs it for warranty (in future).
See how smart these new pals are. May be we are all idiots to unlock it without giving a second thought. lolz
I do not have yet any fault, I just want to try alternative rom and I want to have way back to stock rom
My last phone had after 3 month of use some problem and I must return it. So I just want to know if it is possible
I thought that flashing the stock u-boot & x-boot will re-lock the bootloader.

Maybe this should be in a sticky post somewhere. I have seen a few people ask about re-locking the bootloader.
If this works, we should start collecting u-boot & x-boot images.
There is no way to relock bootloader. Here is good post about bootloader and omap4430, it applies to L9s. In our case ics xloader ,uboot or both simply don't recognize that bootloader had been unlocked and it just appears locked.
I see. Thanks you.
So, you guys with unlocked bootloader, have no problem with fact that your devices have no warranty?
If you don't mention the unlocked bootloader to the customer service and your device has an unrooted stock ROM, there is only a few chance that they check the bootloader if it is for an hardware issue.
It only requires a little bit luck .

With locked bootloader, then install cwm. May I then install cyanogenmod and if something goes wrong may i return to original stock rom together with warranty?

cwm requires unlocked bootloader
I think you need to install the "CWM Recovery" bootloader to flash a custom ROM. And with a locked bootloader, you can only have a bootloader signed by LG (not a "CWM Recovery" one).
However, you can try this : http://forum.xda-developers.com/showthread.php?t=2095825
It is a "CWM Recovery" which is not directly placed inside the bootloader (instead, it adds a step on Android start). When I tried it on my P760 (when it still had a locked bootloader), it failed (but you can still try).

Actually that recovery will not work on jb,
Ok, that's why it failed for me.
Now, you have your answer, you must stay on ICS if you wish to keep your bootloader locked with CWM Recovery.
However, I would be curious to know what happens if a JB ROM (custom or stock) is installed through using this "locked bootloader CWM Recovery".

I received "Security Error" when attempting to boot when I tried this a while back. It just won't work because the kernel needs to be signed by LG.
So may I at least root phone or even root is not possible without unlocked bootloader?

Root is possible with boolloader, try this method (it worked fine for me while I wasn't on an unlocked bootloader) :

so i'm about to install 4.5.91 in a few hours.. gonna backup lots of data first..
im trying to avoid bootloader unlocking for the meanwhile cause of the warranty issue and the fact u cannot re-lock.
anyway i just grabbed ATT-2.3.4_Pudding_preroot.rar and ill flash it over the gladiatrix 1.8.3 i have currently on the device (will it work?)
later i intend to use the preroot method and root and of course.. install a recovery BUT.. since the new recovery needs an unlocked bootloader.. ill use the previous one with the battery charging hack
so.. what do you think guys? will it work?

I would assume the att-2.3.4_pudding_preroot already is preunlocked (hence the pudding) which defeats your purpose?
Also, what would the purposed of the old plugged in Recovery? It won't install any of the new ROMs and I don't think the nandroid back up really works that well.
not quite.. its just have the "pudding" in it.. you'll have to perform an unlock with fastboot to void warranty.

Ok, so the other question - point of the old recovery? Just to help you wipe data/cache/batterystats?
The old recovery will still save him... You shouldn't need to be unlocked to do that.

save him from what and how? other than wiping data... he can't flash anything that can save him...
Indeed I think he can backup with old tenfar's recovery. The problem is that the sfb he wants to flash is the incorrect one, you can't use the prerooted without unlock the BL at least for the version I know. In other hand The update process is kinda complicated without unlocking the BL, if you do it OTA you will also update the BL and that one can't be unlocked now also could leave you bricked if flash back to 1.8.3.

Hello,
I am only user, so no detailed knowledge about Android. But I am able to read instruction, so I've flashed often ROMs and also Kernel without problems.
(BTW - nice forum - and thanks to all developers to give us the chance to modify mobile phone)
Last time after flashing CM7.22 + nAa-Kernel (I flashed without SIM inside) I had no GSM after inserting SIM-Card. All other functions works normally (in Stock-ROM only in flight mode - in normal mode it hangs).
After that I tried several things:
- PC Companion Repair - so flashing Stock ROM
- SEUS flashing Stock Rom
- Bootloader unlock
- Root again
- Other Kernel /ROMs
- Flashing Stock-ROM with bootloader
All time no GSM. Can I do anything else ? Can it be Software failure, or maybe random Hardware failure, happens just when I flashed....?
Has somebody an idea ? Or is it bricked ?
X10 MINI or MINI PRO?
Also, if your deviced was branded (I mean if it has some carrier's label on your phone or apps pre-installed) and supposing you unlock bootloader, the GSM gets disabled. When you flash stock, bootloader gets patched and you have GSM again, I think or you've lost it forever and you need to recover it with
Also please, post in the correct section, this is a Q/A thread.
A known quote from SpyderX
If the simlock certificate specified is SEMC SIMLOCK CERTIFICATE, or anything other than NOT RECOGNIZED SIMLOCK CERTIFICATE, or if you are sure you sim-unlocked your phone using Omnius, jump to step 3.
If the simlock certificate specified is NOT RECOGNIZED SIMLOCK CERTIFICATE, you can't unlock the bootloader of your phone. If you try, radio capability of your phone will be disabled (this has been reported to be untrue by a number of people who claim to have unlocked bootloader successfully with msm7227_semc.cmd).
Do note that the SIMLOCK certificate doesn't mean that you have/don't have a sim lock on your phone.

In fact, bootloader was never unlocked, it was backdoored patched, thus, when you flash stock the patch is replaced with stock "file" resulting a "bootloader lock".
Your argument is totally invalid. I had unlocked bootloader, flashed back to stock and bootloader was locked, I couldn't flash kernel. So I unlocked again.
I can confirm you are wrong, because I did many tests on bootloader locking/unlocking.
No offence,
Thank you.

I don't meant to prolong this out of place thread, but..
How do you unlock your bootloader ? When I unlock it using flashtool, I never got mine locked again, even after flashing back to stock rom / kernel using flashtool or SEUS as well... I can just flash another kernel after SEUS-ing it, without the need to unlocking it again. .
How can your phone locked itself again ?

I never used FlashTool for bootloader unlocking, always the old traditional way of patching bootlaoder with s1tools.
Unlocking with FlashTool might be the issue. I can't tell how to lock it again, I only know that this is due to FlashTool.

Hi,
at first so good news - phone works - very good feeling to write this !!!
I posted my problem in Q/A-section (sorry again for posting my question here first).
Roughly explained I got hints - so I flashed Stock-ROM again, then I relocked bootloader with S1tool, and suddenly phone works correctly.
I don't know what and when I did a failure with the result of GSM failure. But problem is solved. So thanks to all who has tried to help.

do you unlocked bootloader?
Hi everyone, i 'm going to be concise. I own an HTC onex+ international version (it should be no brand) and i would like to unroot it and reset to factory for a warranty issue. I'm extremely noob so i would like, if it's possibile, the fastest, easyest and safest way to do so.
On internet i found several guides about it as http://onexroot.com/one-x-unroot/how-to-unroot-rooted-htc-one-x/ or http://theunlockr.com/2012/12/28/how-to-unroot-the-htc-one-x-2/ BUT i found also an xda tool http://forum.xda-developers.com/showthread.php?t=1870652&nocache=1 that sounds appropriate to me; i read on other forum that i need some kind of extra instrument like boot.img
There are some things to take note of. The boot.img and HBoot image flashing requires users to get their own files as those are device specific and aren’t included

thank you in advance.
relock bootloader and install RUU and you are back on Stock
but would you be back on stock for a warranty issue, you didn't must do that.
warranty has nothing to do with your firmware or root or bootloader unlock.
they would be erase all at your phone and flash the RUU

if you dont touch the bootloader it says: LOCKED
if you unlocked bootloader it says: UNLOCKED
if you relocked bootloader it says: RELOCKED
we can never go back to LOCKED (RELOCKED is technical the same like LOCKED, but it shows as RELOCKED) all people can see that the bootloader was touched by the user
so it cant the reason for that
to relock:
boot into bootloader
and execute this command in fastboot:
fastboot oem lock
now you can install your latest RUU (RUU is the Stock Firmware from HTC as *.exe to install from Windows [depends on your CID])
The other day, I set about installing Cyanogenmod 11 on my Xperia Z2 D5603. I was already rooted on the stock rom 4.4.4 Kitkat 23.0.1.A.0.167. I used flashtool to downgrade to 4.4.2 17.1.2.A.0.314, rerooted it, and installed dualrecovery from this link: http://forum.xda-developers.com/showthread.php?t=2785598
But upon choosing reboot after flashing the custom ROM via TWRP, the phone went dark, and wouldn't turn on. The only response I got was a quick vibration every second or two if I hold down the power button. I could not access recovery either.
I was able to revive it by using flashtool to reflash 4.4.2 17.1.2.A.0.314. I tried the same procedure with AOKP ROM, which had the same result. After trying many different things, I realized that factory reset, or wiping 'system' under advanced wipe would cause this to happen. Flashing without factory reset either returns an error, or finishes, but doesn't actually flash the ROM (stock ROM boots)
How to I flash a ROM without this happening? Any help is appreciated.
Have you unlocked your bootloader? It doesn't sound like it.
These roms require another kernel and you need to unlock your bootloader to install it.

Hmm no.
Root ! = unlocked bootloader.
Go to the sony website ( http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader) to get instructions to unlock your bootloader.
But with your first assumption in mind, I suggest you read up about it first. Understand the risks and limitations.

Perfect! I unlocked the bootloader by using the instructions on sony's website. It did the trick, and CM11 is running successfully.
Thanks so much!
I have this PadFone S for over a week, and it's my 5th android device, but certainly the 1st one having a locked bootloader. So far I have read how to flash stock firmware, how to root and unroot, which requires unlocking bootloader first using CrowLock, how to install CWM and CM12 etc. I haven't try anything yet (still uprooted, and my bootloader is still unlocked).
One question still unanswered, is there any way to lock the bootloader after it's unlocked ? Perhaps by using the CrowLock app, or simply flashing stock firmware ? I need to be assured that any changes I do is reversible.
Thanks in advance
I too purchased the Padfone S and have the same question. Also, does anyone know if flashing crowlock will void the warranty of the phone? Can someone who has unlocked their bootloader using crowlock paste the output of "fastboot oem device-info"?
Does Asus' bootloader not check the signature for the recovery partition before booting from recovery? Given that everyone is flashing the recovery after rooting and running crowlock from the recovery, it seems so, but I'm not sure.
Anyone know if the bootloader's source code is available? I know it's based on the littlekernel, but I'm not sure which version it was built from.
Bump! I need the answer too.
