doubt - General Questions and Answers

I have a doubt related to android OS.Suppose i unlock my bootloader (just only unlock the bootloader ,no rooting,no custom recovery installation).Now, can i install OTA updates with this unlocked bootloader.

I don't think so because while installing the new ota update would probably check whether the bootloader is locked or no.You can try otherwise and let us know how it went.

You can with an unlocked bootloader as long as you make no changes to your /system partition.

How do you update the bootloader?

Does the bootloader update when you install a new version of a stock rom such as 2.3.4 or how do you update it?
No, once you unlock it, it's going to stay unlocked unless you do a fastboot oem lock
There is no such thing as updating the bootloader

[Q] Question regarding the Xperia J

Right now I have the 4.0.4 Android( stock version) of the xperia j with locked bootloader and I've rooted-it and I've also installed the CWM.
I would like to install Cyanogen Mod 10.1 but since I have the 11.0.A.7.5 firmware I have locked bootloader and I can not flash it.
My question is if I can flash an older stock firmware and by doing so will I be able to unlock my bootloader?
From what I understand right now since I have a locked bootloader I can only flash stock ROMs so if that is correct than can I just flash an older stock ROM, one that will allow me to unlock my bootloader and than flash CM 10.1 on my Xperia J?
And another question- I know that by unlocking the bootloader I will also loose my warranty but from searching the XDA forums I saw that I can make a backup copy of my stock ROM and flash it to relock the bootloader again. Is that accurate ?
Thanks in advance for your help!
First is your bootloader unlockable. Then you can unlock on any firmware via sonys website. I dont think there's a cm10.1 released for j. If you unlock your bootloader you will loose DRM keys forever even if you relock they will still be gone that's how Sony will know your bootloader was unlocked.
It is not unlockable, that is why I wanted to flash another version of a stock ICS.
Won't that allow me to unlock the bootloader ?
From what I understood right now I can only flash stock Roms with the locked bootloader, is it correct or since I have the "NO" status at the bootloader I can't even do any of that ?

[Q] Will an unlocked bootloader remain unlocked after Lollipop update?

Hi all,
I have a rooted and unlocked Nexus 5. Just wondering if my bootloader will remain unlocked after Lollipop update, either through OTA or factory image. I need the bootloader to remain unlocked in case an unlocked bootloader becomes the prerequisite for rooting forever.
Thanks!

The bootloader will only lock if you specifically lock it using fastboot or an app. No other way

So a locked bootloader remains locked and an unlocked one stays unlocked if I don't change anything in the OTA zip or Factory Image when flashing? Or don't specify it in adb?

Yes. Though fastboot is not adb. two different things

[Q] Enabling tethering and stock Lollipop

I'm in 4.4.4 stock, locked bootloader, non-root and s-on. I want to be in stock lollipop with tethering enabled. I'm not in US
I know that I can get s-off with WeakSauce+sunshine (then root, unlock bootloader and enable tethering) , but since i'm not in US I can't get OTA update, then I have to use RUU.
Then I'm thinking to get s-off, apply Lollipop RUU, but to enable tethering i need a custom recovery, then I need to unlock bootloader. But to unlock the bootloader I need root (since I can't unlock it by htcdev) and I can't root if i have locked bootloader.
Any ideas?
the same to me, but now I have updated 5.0.1,also s-on and locked.

Sunshine gets you s-off and unlocks your bootloader so that shouldn't be a problem for you. Make sure you get s-off before you update to lollipop. Sunshine doesn't support lollipop yet. Once you have a custom recovery installed it's a simple matter of flashing a zip file in recovery to get root access.

bootloader relock

hello guys, im new here.
anybody tried relocking their bootloader by using this command?
fastboot oem lock
and does it work and restores warranty conditions?
That command has been tried since the original Moto G and no, contrary to what some people think you can't reset the internal unlock counter. They will always know you unlocked it. If nothing else, they know because you got the unlock code from them. I'm not sure why people overlook this clearly posted sentence when they request the unlock code from Motorola.
"Unless you have a Developer Edition device, once you get the unlock code, your device is no longer covered by the Motorola warranty; in other words, please don't blame us if things go wrong, even if they appear unrelated to unlocking the bootloader."

That command will lock your bootloader again. However, locking and unlocking will wipe your device.
Upon receiving your unlock code from Motorola, your warranty is void; regardless if you unlock it or not. The sheer act of asking for and receiving the code voids your warranty.
Of course, if there is a true hardware issue that is not caused by software tinkering, you can still use that piece of the warranty.

Yes you will be able to get over the air updates after relocking bootloader if necessary system apps and files are not modified.
If you are not able to get ota you could also flash stick firmware images.
Thanks man... I flashed the whole stock rom from xda here only...
Even though I've run the commands to re-lock, going into the fastboot (bootloader) mode shows it's unlocked.
Anyone figure out a way to actually re-lock it?

No, once it's unlocked, the counter will always show an unlocked bootloader. Best you can do is hide the opening unlocked bootloader screen.
In the 1st Moto G i have sucessfully relocked the bootloader.
You can use the command 'fastboot oem lock begin', then flash all files from fastboot firmware changing the logo file to logo-mod.bin (File that have removed the unlocked warning image, because flashing custom logo.bin doesn't check crc or hash when relocking the bootloader), then finish with 'fastboot oem lock' command.
Example:
fastboot oem lock begin
fastboot flash partition gpt.bin
- - - rest of commands
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot oem lock
I don't have tested because i don't have unlocked my g3 bootloader yet.
Just try

Been there, done that, got the T-Shirt, doesn't stop the banner from saying the bootloader is unlocked.

Have you flashed moded logo.bin?
I still don't understand the point of all this... why are people trying to go through all the work of relocking the bootloader?!?! There is ZERO benefit to it... your warranty is still void (you don't even have to unlock, just agree to the terms and get the unlock token), it doesn't enhance resale value, it doesn't change the performance, so why all the effort to try to do it?!?!

Hmm... Are you sure? If you are unlocked but otherwise pure stock, you should still get OTAs, if your not then they are most likely blocked server-side not client-side. In other words just accepting the T&C of a Motorola bootloader unlock could not only void your warranty, but also blacklist your IMEI from OTAs as well.
I could be wrong, but I think your "barking up the wrong tree" here... I can tell you for sure that Huawei does it this way since Lollipop, if you unlock the bootloader your IMEI is blacklisted server-side... They are very straightforward about it.

not at all... already flashed official firmware 3 times after experiencing the less battery backup on custom roms. in this 3 times i flashed the modified bootlogo so didnt got the warning of bootloader unstlocked and not able to get the OTA but then again i flashed the official firmware 4th time and without that modified bootlogo in hope to get the latest OTA build no. LPI23.72-65 and it worked i got that update next day... and still its show bootloader unlocked warning... so that warnling doesn't affect the OTA is you have everything stock with locked bootloder.
Can anyone post a modified logo without the unlocked warning? My bootlock is relocked but i wanna get rid of this message. Thanks!
Just to clear up any confusion. There is no need to relock the bootloader. In fact it seems like a waste of time to me...

After I unlock my device bootloader, am I still eligible to receive software upgrades from Motorola?
Unlocking your bootloader does not affect your eligibility to receive over-the-air (OTA) upgrades from Motorola. Upgrade packages to new versions of Android will be pushed to all eligible devices, regardless of their bootloader locking status.
