[Script] Moto G US 4.4.2 Firmware Restore, Relock bootloader and flash Moto Logo

[nlra]

I am talking about stock rom always, no custom rom. With stock rom you can relock bl.

Incorrect. You cannot relock the bootloader on any Moto G without reflashing the stock ROM again during the procedure, even if you are already running stock. So there is no way to leave the phone rooted and then re-lock the bootloader. If you are still running stock but have modified it in the slightest (e.g., root), all of your changes will be wiped out during the re-locking procedure.

Procedure is:

fastboot oem lock begin
...various 'fastboot' commands to flash the different parts of the ROM...
fastboot oem lock

I know.

There is nothing wrong in my reply: "You can relock bl only on stock rom". Why you quoted me buddy?

Thank you Nathan. That's the answer I was looking for.
I have a few more questions if you could help me out please:

1. Is there a difference between STOCK ROM and STOCK RECOVERY? Say if I have STOCK ROM AND STOCK RECOVERY with SUPERSU installed, and later on i flash STOCK RECOVERY (not rom) would it enable me to relock bootloader? If so where can I find a STOCK RECOVERY?

2. If bootloader is unlocked first time, and subsequent relocks would still enable the data to be wiped clean upon unlocking?

3. I think I solved my problem sort of by installing AVAST MOBILE SECURITY ANTI THEFT. What it did was disable USB DEBUGGING. Do you reckon that now I dont really need to relock bootloader?

4. While unlocking bootloader it gave a stern warning on the lines of it might even cause PHYSICAL HARM or INJURY. I'm kind of scared about it. Do you reckon its safe to keep bootloader unlocked?

 

[denzel09]

You need a serious reading of all this forum and all basic guides about android or you will risk to do only damages. Seriously.
By the way why you or others need to relock bootloader?
What it the purpose?

Your reply was clearly made in the context of somebody asking whether or not they could unlock, flash stock ROM, root it, and then relock while keeping root. You can't do this. When you relock, you are forced to reflash the ROM and undo any modifications you made to it, including root.

You yourself even said in a previous message:

if you unlock bl, then root, then relock it so the root should remain and work easily i think

My point is that this is *not* possible. So I'm not sure why you are confused that I called you out on this.

1. Is there a difference between STOCK ROM and STOCK RECOVERY?

Recovery is just one aspect of the ROM. In reality, Recovery is a second partition on the flash chip that contains a bare-minimum installation of Android (along with a few simple diagnostic tools) that you can boot into if your main Android installation gets trashed and you want to attempt repair or maintenance on it.

2. If bootloader is unlocked first time, and subsequent relocks would still enable the data to be wiped clean upon unlocking?

I am not sure I understand the question.

3. I think I solved my problem sort of by installing AVAST MOBILE SECURITY ANTI THEFT. What it did was disable USB DEBUGGING. Do you reckon that now I dont really need to relock bootloader?

Why did you think you needed to undertake relocking the boot loader in the first place?

4. While unlocking bootloader it gave a stern warning on the lines of it might even cause PHYSICAL HARM or INJURY. I'm kind of scared about it. Do you reckon its safe to keep bootloader unlocked?

Generally speaking, it should be fine. The warning is there because without a locked bootloader, some software protections have been removed that might normally prevent hardware damage from occurring that is not easily repairable or reversible (for example, somebody either maliciously or accidentally flashing the wrong thing to the modem baseband chip, which would probably brick the RF part -- WiFi and cellular functionality -- of the phone, or perhaps somebody overclocking the CPU beyond its natural bounds and thus shortening its lifespan). Just be smart about what you do and what software you install (and what sources of software you trust).

Good question, and one that I also asked him. There are valid reasons for somebody to want to have their boot loader locked, such as the ability to continue to be offered and receive OTA updates rather than having to install them manually. Or, in the States, where Motorola has an all-too-common bias against phones running modified software, sending in an unlocked phone with a manufacturing defect to be repaired could result in your claim being rejected and your warranty voided, even in cases where it is abundantly clear that the modified software played no part in the hardware defect. (Unfortunately, Moto phones keep track of whether they have ever been unlocked, so even if you relock it, Moto can tell that it was unlocked at some point in its past, and still consider your warranty voided.)

I'm not sure why 'shmotog' in particular wants to relock his/her phone though.

Like written i don't know, because i never tried, it's completely unseful in this case, but in theory it should be like in other phones, from this my reply.
You tried? The next point was that on stock it's possible relock bootloader, this was the point. But if you tried and seen that it's need reflash rom also if this last it's completely stock without root, so ok

It's completely unseful relock bl, completely, first for that you writed, motorola can know always that bl has been unlocked at least one time, and second, you can receive OTA also with bl unlocked, my last 2 ota were with bl unlocked. There are not problems with bl unlocked and OTA. This last i tried

I do not care aobut motorola knowing, i do NOT want OTA. The purpose I wanted to relock bootloader, is simply so that adb commands cant be executed by a third party and my data would be wiped if they try to unlock bootloader.

Thanks for the reply Nathan, that really helped me. And the reason why I wanted bootloader re-locked is:

1. So that no one could exec adb pull commands and such in recovery as a locked bootloader wont allow this. So security is the reason. If they do it they would have to unlock bootloader which would execute wipe of my data which would mean that security would stay.

2. I was afraid of the 'physical injury' warning. I though relocking bootloader would make the phone 'safe'. However I understand from your reply that even if I do that, once its rooted, the bootloader doesnt matter.

 

[denzel09]

I do not care aobut motorola knowing, i do NOT want OTA. The purpose I wanted to relock bootloader, if you would only read what I wrote, is simply so that adb commands cant be executed by a third party and my data would be wiped if they try to unlock bootloader.

There is nothing between "i do NOT want OTA" and relock/unlock bootlodaer, really nothing. About the "security purpose", also here it's a bit unsense, who want that do all that on your phone:laugh: I don't think the reason is this.
Listen me, it's completely unseful relock bootloader for OTA updates, for not OTA updates or for warranty. But if you want that for "security reason" you must follow the procedure that you can find in many guides in this section, the input is what nlra has written before. So you will have a relock bootloader. :highfive:

 

[amazingone]

@denzel09 So if i got it, lock again bootloader is not good for warranty?

 

[denzel09]

@denzel09 So if i got it, lock again bootloader is not good for warranty?

This is a good question. Yes, in this case there is a qfuse, software, through which motorola always will know the unlock. :good:

Get some fresh air lads, things here are going a bit rough isn't it? I had to delete/edit some of the comments of this thread. Stay on topic, don't show disrespect to others, don't reply in a sarcasm or rude manner. If it happens next time, I will have to address users who are involved via PM. I don't think anyone would want that. Have a good day

 

[wrbl]

I was doing this method but on Tesco Moto G the option to flash the Rom and do everything is not working.

 

[abhishekk89]

I'm on stock ROM (rooted with unlocked bootloader) and have the latest update 4.4.3. I had a small hardware issue and I need to get the phone serviced. I hence have to relock the bootloader (consequently flash the stock ROM). Can it be done using this tutorial ? Are there any issues flashing the older 4.4.2 ROM ?

The link to the firmware tool doesn't work.

No, it doesn't. The link in the OP, when I click on it, says file doesn't exist.

Relock 4.4.4 XT1033 India version ?

wanna relock bootloader
android version KK 4.4.4

system version
210.12.40.falcon_umtsds.AsiaRetail.en.03

i got BIG problem

 

[lonaysta]

Yes you can relock and unlock the bootloader with the same code you unlock it with the first time.
when you got the device the bootloader is status code 0 locked once unlocked it is status code 3 and relocked is status code 2.
now you can bounce between status code 2 and 3 locked and unlocked with the bootloader unlock code.

Hi, I don't know if you're still active around here but this thread helps me a lot. I'd appreciate more if you could help clarify on this little confusion that I have.
Here's the information I comprehend. According to the post, the bootloader of Moto G (Gen 1 for the discussion. More precisely, I have a US Retail XT1034) has three status to show the lock status:
Status 0: never unlocked, warranty valid if not expired.
Status 3: unlocked, warranty void.
Status 2: unlocked before but relocked, warranty voided before.
Besides, for the full stock firmware, status 2 and 3 share a same logo.bin image with warning, while the status 0 has the "untainted" version.

Do I get it correctly?

My Moto G is relocked and showing status 2 and that warning screen. So the only way to get rid of that warning screen is to manually fastboot flash logo custom_logo.bin to overwrite the stock one. Is that correct? I'm quite happy that doing so doesn't require an unlocked bootloader
