Dears,
Is it the case that after flashing a firmware and (locking then unlocking bootloader) everything is deleted from the phone even the SDcard data?

Why did you lock the bootloader in the first place? I guess the unlocking process wiped everything, though, it should not wipe the sd card.

unlocking does wipe the data. or my second guess will be the firmware
usually firmware flash tend not to wipe sd data but some firmwares do wipe the whole thing

Without s-off it is necessary to lock/unlock device to flash firmware zip. That usually wipes it, supposedly for "safety" reasons.
In the future, you may want to s-off so lock/unlock is not necessary. Also, most firmware uploads on XDA say whether or not they will wipe data/sdcard.

I am on stock just unlocked bootloader and rooted.Will simply relocking bootloader and unrooting help to get updates?or I need to reflash stock Rom?
I am not sure about this, but the only reason you can't do OTA's with the bootloader unlocked is because the unlocking procedure deletes some of the built-in apps in HTC Sense. The phone will check for these apps when it tries to update and fail if they are not present. There is a thread somewhere in XDA which tries to solve this issue of apps being deleted when unlocking the bootloader.
You have to flash stock Rom, stock recovery, then relock to receive OTAs. At least that has been the case in all other HTC phones. The HTC one might be different since a couple of apps that come with the phone are not in the system partition and get wiped when you unlock the bootloader.

OT: The removed apps can be reinstalled here.

Well I havent flashed any other Rom. Just wondering if after unlocking bootloader some apps disappear, does that mean I need to reflash stock Rom. Don't think that simply relocking bootloader will bring them apps back. Hope someone can confirm that
When you unlock the data partition is wiped. Some of the apps that the ota looks for are in that partition. So you either have to flash a stock Rom or restore those missing apps before you relock.

Granted, I'm basing this on the HTC Droid Incredible, nearly a three year old phone, but with us you just have to have the standard HTC apps that it checks for, and the stock recovery to flash it. You could keep the bootloader unlocked, since the unlocked bootloader can take the same commands as the locked one, it just doesn't check for signatures. Again, this is based on a different device, so it may or may not work.
Hello everyone. Thanks for those who help me forward.
I've got a x8 which have a stock rom. The phone was sim locked to vodafone hungary, but i bought a software about a half yea ago, and it has benn unlocked, but the unlock wasnt permament as i remember. If i'll chnage the rom, the phone will be Vodafone locked again? can i change the rom and keep it unlocked?
You can change the rom/kernel after the sim unlock, you will NOT lost it.
are you sure? cuz then i will put on a 2.3.7 custom rom. btw i used the software of this site to unlock, htccode (called ezsemc s1 android v1.22, instead bypass unlock)and not the permament unlock, the other one.
I'm 99.9999% sure. Not tried the htccode method, but all other medhod (omnius, setool, plasmatool) is permanent (my x8 was also vodafone hu locked, unlocked with plasmatool). And finally: if the htccode method store anything on the visible partitions (system, data, cache), you can restore the previous rom from a backup.

i believe if you say, just in the program there was 2 option, first bypass unlock second full unlock, and i used the first, which is the bypass one.

but if u tell me to go on so, i'll try then.
This is your choice. As I wrote: I'm 99.999% sure the sim unlock not restored after a new rom install. If the sim unlock possible with writing something into the /system partition (what formatted with a new rom install) the people why use paid methods?
If you not sure: google about your used unlock method.

I'm kinda worn out by the slow release of updates and would like to go CM.
Having locked bootloader, I am unclear from reading/searching if I can, say in a few months, go back to stock (flash using FlashTool?) so I can sell the phone before I upgrade?
Thanks for any tips or RTFM links. :good:
You can't flash CM with a locked bootloader. CM needs a modified kernel to work and with a LB you can't do that. But to answer your question, yes you can. Simply wipe everything before flashing with flashtool and you are good to go.

So, in my case I need to
1. Unlock Bootloader (which will erase everything, including SD card)
2. Flash CM
3. Enjoy until time comes to sell device
4. Wipe data/cache/factory reset
5. FlashTool the latest STOCK I find
Is it accurate to assume that after step 5, the only difference between my (current) stock device and then will be unlocked bootloader (with zero impact for guy who buys after me) ? As much as I want to have KitKat, I do not want the buyer to be funked with something not matching his/her needs or impaired somehow...
Thank you for the confirmation :good:

After step 5 you can relock your BL by reflashing your TA partition (which you should backup before step 1) if i'm not mistaken.
Step 1) backup TA partition.
Step 2) unlock bootloader.
Step 3) flash cm.
Use as you wish.
When you want to sell device.
Step 1) Restore TA partition.
TA restore will block to boot with modified boot image.
Step 3) flash stock fw via flashtool. Do not select or unselect anything in flashtool.
That will flash full device including sdcard.

What is the risk of not reflashing the TA partition and flashing STOCK onto unlocked BL? Not receiving OTA updates or something more complex?

You lose your DRM keys. People say bravia engine stops working on photos and some stuff with the music info downloading with walkman. Unsure about OTA updates, as i have never done those. I flash FTF as soon as they get available.
Other than that, there is nothing different.

The SD card shouldn't get wiped when unlocking but the internal storage does.

Thank you to all who pitched in - I searched the fora for "TA partition" and discovered that [NUT has written a wonderful thread for people who have my question, I wish I knew about the TA partition importance and searched earlier.
For those who follow or need the same thing, thread is here: http://forum.xda-developers.com/showthread.php?t=2458530

Hey folks. Got a Dev edition here, which as I understand is easy to unlock. Question is must I lose my data when doing so? And if yes, how can I backup before unlocking? If I had root, I would run titanium backup, but given that I can't get root until I unlock, this seems like a chicken and egg problem....

Yes, doing the. Mfastboot oem unlock will factory reset the phone. You will lose apps and data. I am not familiar with a way (while not rooted) to back up everything and restore after unlocking such that everything is the same.
I may be wrong.....just going from memory of what I've read, but I think an app called helium can backup without root. Then you'd need to transfer the backup off the phone, cause everything is gone when you unlock. Pics too.
Hm. Can anyone confirm this happens for sure? On the Galaxy Nexus, people said the same thing but it turned out that if you just typed fastboot oem unlock without flashing any partitions that no data was actually erased. I just can't understand why unlocking would be linked to erasing.
Thanks!

Unlocking erases everything. On any device I've owned. The x for sure.
Why? Dunno. Lol
Unlocking the bootloader will reset the phone back to factory fresh condition as stated. When I unlocked my Moto X it was factory reset. Same for when I unlocked the bootloader in my Nexus 10, Droid Razr M, Incredible and Eris. I think this is the normal behavior.
There are ways to back up your data and apps even without an unlocked or rooted phone. There is a toolkit in this forum somewhere for the Moto X that will do that as well as a market app (Helium?). I used the toolkit here:
http://forum.xda-developers.com/moto-x/development/tool-moto-x-toolkit-v1-2-1-t2477132
But I did that while at 4.4, before the OTA update to 4.4.2.
Any tool to recover files from a recently formatted device by unlocking the bootloader? thanks.
No. "Format" means "Blotto Everything". That's exactly what happens.
IMO seems to be a commercial "feature" more than a technical limitation. The simply want to discourage you to unlock the bootlader. All along the process, there is a warning message telling you that unlocking the bootloader will make the phone less secure. A subliminal message from Xiaomi : Blessed be the freely included uninstallable without root - and by extention unlocking the bootloader... D'oh!- bloatware package ! Or go to hell with your data if you dare to spit on it!
If you are able to install twrp, does that mean that the phone is already unlocked? I've already deleted my stock android and I couldn't see any options there at all of unlocking the oem directly in the settings, but I was able to install twrp itself (2.6).
Title says it all really.
I previously had rooted my old HTC Wildfire S and that had a removable SD Card but with the HTC One M7, if I unlock the bootloader through HTCDev and flash a recovery etc, does this affect data on the /sdcard partition?
Will it get wiped? Cheers

Unlocking the bootloader will wipe your device, after that though you can flash recoveries, rom's, kernels whatever without wiping your sd card.
So if your going to unlock backup your internal storage to your pc first. After you've unlocked you can copy it back. Then you can flash a rom or or whatever without losing it :good:

like already said, /data is wiped during the bootloader unlocking process so yes /sdcard will be wiped because /sdcard is a simlink to /data/media/0.
And don't forget about /data/preload (preloaded HTC apps and weather animations) which will also be wiped thus preventing the installation of future ota updates and obviously, you won't have HTC apps anymore (flashlight, calculator...) on your phone nor weather animations in the weather app. (unless that folder is restored after the bootloader unlock).
