Unlocking bootloader or flashing custom ROM doesnt void your warranty!

| 0 comments |
Since HTC started htcdev.com with the possibility to unlock bootloader on HTC devices, I noticed that false information and beliefs are spreading around the world and more and more people think (and tell!) other users, that their warranty will be voided after unlocking particular device. This is not true!

In the past I wrote a short article on xda-developers about warranties and why, against common believes, flashing custom ROMs does not void your warranty. You can find this thread here.

Heres some information worth pointing out:
  1. Warranty is a contract. In every country there are laws and regulations about warranties, however these vary from place to place and may be slightly different in your country, keep that in mind.
  2. If its a contract, then both sides have some obligations and rights. Both - rights and obligations - needs to be written in the warranty, otherwise they doesnt exist. Warranty statements must be consistent with generally applicable law.
  3. As a contract, warranty can be created as the parties want, as long as its consistent with generally applicable law.
  4. To know exactly whats written in your warranty dont try to Google it - take it out of the box and READ IT. Dont trust what others say - their warranty might be different to your own.
Now, the question is - why unlocking the bootloader doesnt void the warranty? The answer is very simple. Because HTCs warranty contract doesnt state it. The only information about warranty on htcdev.com you can find is this:



So, once again:

"It is our responsibility to caution you that not all claims resulting or caused by or from the unlocking of the bootloader may be covered under warranty."

Is there any information, that unlocking bootloader voids warranty? Nope. So basically, what does it mean? Only this - if you brick your device as a result of e.g. flashing custom ROM (unlocked bootloader allows you doing that), you may have no warranty claim for that particular incident.

Two more important things to conclude:
  1. If "not all claims may be covered under warranty", then (logic conversion) some claims may still be covered under warranty.
  2. Even if you cant claim something under warranty because it was caused by or from the unlocking of the bootloader, that doesnt mean you have lost your warranty. You still have your warranty and you still can claim under warranty, but this warranty wont cover those particular claims caused by or from the unlocking of the bootloader.
So basically, HTC warns you, that some of the actions you might take after unlocking the bootloader may lead to a situation, when particular issue cant be covered under warranty.

Also, this information on htcdev.com doesnt expand or restrict your warranty terms. It doesnt change it at all. If warranty is given in the paper form, then as a contract the only way to change it, is a paper form too (if not stated otherwise in the warranty itself). HTC just kindly reminds you some sort of information you can conclude from the warranty itself.

Once again, if you are interested why flashing custom ROMs doesnt void warranty as well, please read this thread.

PS. Im also wondering why Samsung users are so crazy about so called flash counter and "Triangle Away" application. They dont need it to have a valid warranty, even with a yellow triangle.

This text is just for education purpose. Its not a law itself so you cant base your claims versus a company on this. I may be wrong in many parts - feel free to write a comment under this post and I will make any necessary corrections. I dont know the laws in every country so there may be some slight differences.

How to Copy ROM zip file to the freshly wiped device

| 0 comments |

Have you ever been in a situation where you mistakenly (or not) wiped the content of the internal storage (including system partition and virtual SD card) on your phone or tablet and unfortunately it doesnt support external storage? Now you cant flash desired custom ROM because you removed it and the device cant be booted due to wiped system partition. Dont worry - its very easy to fix!

Here are the steps you need to follow to copy the correct rom.zip package to your internal storage:
  1. Download this mini-sdk package and extract it to c:mini-sdk
  2. Rename the custom ROM package you want to flash to "rom.zip" and copy it to c:mini-sdk
  3. Connect your device to the PC
  4. Boot your device in recovery mode
  5. Open a command prompt on the PC (cmd.exe), type and confirm each command with ENTER:
  6. cd /d c:mini-sdk
  7. adb shell
  8. mount /data (error might mean that /data partition is already mounted)
  9. on Android 4.2 and above: mkdir -p /data/media/0
  10. on Android 4.1.2 and below: mkdir -p /data/media
  11. exit
  12. on Android 4.2 and above: adb push rom.zip /data/media/0
  13. on Android 4.1.2 and below: adb push rom.zip /data/media
  14. Wait for a few minutes until the file is copied. It will looks like command shell is not responding, but that means its still copying. Wait patiently until youll see blinking cursor again.
  15. Depends on your custom recovery, use the navigation keys to flash the custom rom.zip package in a typical way you used to flash custom ROMs. It should be on your internal storage now. Done!
