Delta Updates - Thunderbolt General

Excuse my ignorance on this topic. Do any ROM authors use delta updates when rolling out new versions of their ROMs? One thing that has kept me from using custom ROMs is the prospect of wiping the phone every time I want to upgrade the ROM version. Are delta updates even within the realm of possibility for un-official ROMs?

It's not required to wipe with roms, just very strongly suggested. Some people don't wipe, update and say they don't have any problems.

[Q] Restoring to stock

Hello there! I had seen this guide here on XDA and was wondering if it were possible to restore to stock even if I had updated to .30 and then flashed this. Would it be easier to simply place the update file on the root and use the manual install method since this is basically stock with slight mods? I am using TWRP btw, and I wanted to know if this would work. With the JB update coming in a few days I really would like to prepare. And this seems to be the best way (via OTA) no? Thanks!
Your already unlocked. You won't be able to receive ota firmware updates. Best thing to do is wait for the devs to bring it to the unlocked community. They are pretty speedy about it you won't be waiting long.

I'll add to that...they are ready to pounce on the tf700-specific files and what we'll get out of it will far surpass the OTA. At least this has been my experience so far.

Thank you very much. I guess my basic question was would this method still work even after flashing .30 then changing to the ROM I posted about above. But what you're saying is it's not worth it?

[Q] 4.1.1 OTA

Will there be a specific date on when the 4,1,1 (OTA) fix will come in so you can use the AOSP ROMS? or will we just have to wait and see.
(I OTA updated before knowing of rooting, so don't tell me its a no no and stuff )

When kernel source is released
My guess is another two months at least on the kernel. No clue on if or when a fix will ever be released for the jb ota'ers sorry

Noooooo
I'm just guessing I know nothing about the new firmware and hboot from the jb ota. Another guess is once the flood of at&t ota people comes rushing in like a tsunami a solution may pop up shortly after.

From what I understand they have 90 days to release kernel source after releasing the kernel so we're looking at around 3 months. I'm in the same boat as you bud. Updated without realizing the downside and I much prefer aokp to sense. Until then I'm using viper 3.1.0 desensed with nova. I even went as far as to downgrade my hboot to see if I could flash aokp after with no difference.

Damn, I was just going to suggest that and see if it works i guess not. Couldn't we just downgrade to the ICS build by downgrading our hboot then flashing the 2.40 RUU?

Well actually nvm the 2.40 RUU isn't leaked yet i think so couldn't you downgrade to 1.09 and then Flash HK 2.42 RUU which is basically the same?

They DO NOT have 90 days. GPL clearly states it must be provided immediately when the accompanying software is available or before. HTC is in violation of the GPL. They are only allowed time to make it available for distribution. They think that this allows them to hold it back indefinitely while in reality it means time to upload and should always be available within 24 hours of the Rom being released to the public. This is not open to interpretation according to the GPL and any lawyer who has looked at it. Gpl-violations.org is a good place to file a complaint as well as HTC's legal department. This really needs some attention considering they routinely wipe their ass with a legally binding agreement that does not allow delaying kernel source at all.

Somewhat of a noob question, but I'm assuming AOKP ROMs also wouldn't work if I stupidly applied the 4.1.1 OTA update?

Yep only jb sense... And once kernel source is out it will be fixed so be assured and I thought they had 90 days? If they were in violation oh well but I could of sworn they had 90 days to do it either way until they become a dev friendlier community you have to wait at least 90 days for source

im just thinking of getting the nexus 4
So I applied this OTA update (flashed the stock recovery first), then re-flashed TWRP. Now, I can't for the life of me get the phone rooted again. I tried several different supersu apks, some older, some newer. SuperSU itself can't install, can't uninstall, can't update its binaries. Different supersu's allow SuperSU itself root access, but no other programs can be given root access (such as Titanium Backup).
Any ideas? I'm about to get rid of this phone, HTC is just making modding so painful. My fault I know for installing the OTA update, but still...

I installed the 4.1.1 update, so I have that kernel. Are there any kernels I can install that will function with the new update? I was under the impression I had to wait until HTC released their source before I could flash anything.

That should do what you want.
Thanks, I'll look into that.
I have a nandroid backup of my stock ROM (4.0). Would installing that work, or has the 4.1.1 update messed that up too?

Too late, your phone has the new hboot. It probably won't work

[Q] Updates

Do all roms update over the air or is it the user responsibility to do it. If the latter is correct, how do you update a rom.

Revert back to Stock for OTA

I see many different posts on this, but none seem very recent or one post compiled with all info. Here is my situation. I'm on stock rooted rom currently. I did a backup of the original rom after rooting and before deleting or doing anything my current rom. My question is what exactly do i need to do to get the update. I'm honestly looking to stay stock due to the small bugs that always pop up on custom roms. If i just install the update with my current configuration will I just lose root?

If you super CID'd you won't want to ota. Brick brick brick.
Why would you want the ota? its just loaded with even more bloatware

Updates while on custom kernel?

Ok, so I'm no stranger to modding and XDA but every phone I've always had I always flashed custom Roms immediately so I'm not sure how it works on stocks. I'm rooted with unlocked bootloader on the stock ROM with Franco's kernel. Can I install system updates or is it best to do that on stock kernel and does being rooted with unlocked boot loader affect it? Thanks for any help.

The OTA should contain the stock kernel, so you would just need to flash the custom one afterwards. I'm not 100% sure, but I don't see why it should be different from what I said...

Sorry, I wasn't clear: most likely the OTA itself contains the stock kernel, therefore it installs it instead of whatever you already have. After the OTA you should just have to (re-)flash your custom one back and be good to go.

worse case scenario you can flash an update zip but like previously mentioned the kernel is not what generally causes the issue but the recovery. I do not think you will have an issue but hey there are some nice custom roms out there with options give one a shot. Just nandroid you current setup
Remember custom roms are running 4.4.4

Yeah I know, I always use custom Roms cause I generally have phones that have some OEM ui plastered on so since this is already close to stock I'm going to ride it out and see how CM does updating for a bit. Especially since they promised L within 3 months after it's release.
