[Q] Will OTA after SIM unlock break the unlock? - G2 and Desire Z General

Hello everyone,
I've searched the forums for this but I couldn't find an answer, so maybe someone can help me. My goal is to simply SIM unlock my Desire Z and nothing else.
I used gfree to Sim unlock, set SuperCID and Radio S-OFF using the method from the wiki:
http://forum.xda-developers.com/wiki/HTC_Vision#Rooting_the_Vision_.28G2.2FDZ.29_and_DHD.
I did not install a custom ROM and now I am getting a notification to do a system update.
My question is: if I install the OTA update, do I loose the SIM unlock? I am not interested in keeping root privileges (although SuperCID would be nice), I just don't want to have a SIM locked phone. Is it safe to do the OTA update after rooting and does it retain the SIM unlock?
Thanks

Someone can correct me if I'm wrong, but I'm pretty sure it will break it, cause you downgraded to a version that had it unlockable and now if you upgrade I think you lose that.

No, for 100% OTA will not revert you a sim lock in your phone.

Oh wait did I screw up s-off and sim unlock ?

What?!? What's UP?

This is correct once your phone is SIM unlocked a OTA unlock should not do anything to your SIM UNLOCK. if it did then there was something not done during the unlocking.
- My G2 is sim unlocked and has and will be for life

Thanks for the replies guys. So you are saying that if I do the OTA update, there should not be any problems? It will still be unlocked and SuperCID, S-OFF or the eng hboot would not have any negative impact during the update?
Would you do the OTA update if you were me ?
Thanks.

Sim Unlock, S-OFF and SuperCID will remain no matter what you flash on the phone.
The eng hboot might be gone if you flash the OTA though, but will not affect the phone at all if it doesn't.
I'd recommend using a custom rom, but if you don't care for root access, go ahead and flash the OTA

I know what your talking about and I have the same question...but let me be more specific cause I don't think the question was clearly answered..
The phone is rooted ofcourse, s-off, supercid and unlocked with gfree (not perm unlock via code). the update is not a android system update, its the supplemental update that adds wifi calling.. the actually update states that is includes:
*wifi calling for android
*resolves unexpected device freezes and power off issues
*improves data connection reliability
*optimizes radio recovery
So the question is for us running the stock rom with permanent root and unlock will this update break the root, s-off, supercid or the unlock?
***Nipqer you said s-off, supercid and sim unlock will remain no matter what?..are you saying that even if we flash the OTA gingerbread update that i assume will pop up after the supplemental OTA update is flashed that those will still remain??

You ask about SIM lock, ane with root, s-off, supercid is a different way.
It may unroot your phone, but it doesn't remove supercid and s-off (you will still have it like it is).
And Yes, thats correct. When you flash your phone using RUU or other roms you will not change simlock, s-off and supercid from like it is now on your phone.
ps. I'm using MIUI right now, so I can't said (but I will) upgrade or not (do an upgrade).

Question about Nexus One SLCD and unlocking bootloader

Hi all,
i have an Nexus One SLCD and want to flash the US Stock Adroid rom so i can get all further updates directly from google OTA.
I don't need root and i don't care if unlocking my bootloader will void my warranty.
The problem is: all i can find are many FAQs about "rooting without unlocking the bootloader".
Since i'm not interested in any custom roms, can somebody please explain to me how i can flash the stock us rom on my german Nexus One SLCD?
Is there any faq for this available?
As i said my two important points are following:
- i want the us stock rom
- i want OTA updates
I would appreciate a short step-by-step description (i did this with my old Nexus One AMOLED but it seems like the older roms don't work with SLCD devices as the drivers are missing, so in don't know which rom to flash after i unlocked the bootloader).
thanks!
Look in Nexus One Wiki, "Unroot/Restore your Nexus", PASSIMG method.
Flash Korean FRF91 ROM.
AFAIK, there is no US ROM with SLCD support.

thanks! i checked the FAQ and have a question about this:
"Using PASSIMG.ZIP method (adapted from here):
1. Revert HBOOT to older version, if needed (required for pre-FRG33 stock builds and for flashing CyanogenMod ROMs).
* Use the following steps to flash PASSIMG.ZIP that differs from EPF30.
"
it says that i have to revert the HBOOT if i have pre-FRG33 stock build (which is the case for me).
but when opening the link the first post says:
"this is especially useful for people who wish to use the rooting method without unlocking the bootloader. If you already have an unlocked bootloader, there is no reason to follow this guide."
since i want to unlock my bootloader, do i need the above mentioned steps at all?
edit: just saw that you updated your reply. is there really no us rom supporting slcd? i was hoping this was the case as even developer phones should start being sold as SLCD versions...
If you have HBOOT 0.33, then you don't need to downgrade it - which leaves you with easy procedure. I've changed the Wiki to be more understandable.

sorry for the dumb question. But how can i check which HBOOT version i have and if i have HBOOT 0.33, does this mean i don't even have to unlock the bootloader (via fastboot) to be able to flash the US STock ROM?
Reboot to bootloader (fastboot), it'll show you the version at the top of the screen.
Unlocking the bootloader isn't required anyway. If all you want is to have a stock ROM - then keep the phone stock, since unlocking won't be of any use to you.
You can flash US stock ROM (FRF91 PASSIMG - link exists in Wiki), but if you happen to end up with a phone that goes black after "X" splash screen - don't say I didn't tell you

But wouldn't my Vodafone Firmware throw an error if i just try to flash a stock us rom? And i would rather try to directly flash the newest rom, because as you said i don't think that FRF91 supports lcd.
Edit:
sorry i just realized that i haven't even mentioned until now that i'm talking about an european vosdafone nexus one SLCD (FRF91)...
The newest FRG83 ROM doesn't exist yet in PASSIMG version that I'm aware of. If it would exist - or if it appears at some point - it'll be easily flashable over FRF91, no matter what build.
Anyway, looks like Korean ROM won't help you, since it doesn't seem to receive OTAs either (I guessed you have VF version). I'm not aware of any other "clean" FRF91 ROM that supports SLCD, and I've googled it for 1/2 hour. You could wait until FRG83 PASSIMG appears, I guess...
Thanks. I rooted my Nexus One now. Guess I have to wait until the passimg FRG83 emerges. But if I want to keep root I have to wait until the passimg is rooted correct? And how long does it usually take until a new stock build is provided as passimg with root?

my aim is to have a stock us rom (root is no must - so no problem if i lose it during the process. currently i have a rooted vodafone FRF91 device.)
No you can't use that to upgrade the Voda ROM.
As it stands now you'd have to root the phone (using UniversalAndroot if you want to stay locked), and use fastboot or flash_image to "update" system.img and boot.img to the USA/Google orginal ones.

i have unlocked my bootloader now and rooted my device. is there any manual on how i can update system.img and boot.img with fastboot. And where can i find those files? Is there a risk to get a blank screen (SLCD)?

[Q] Verizon 2.3.4 out. Is it possible to get a ftf or update.zip of this

As I stated in the title. Anyone know how long the wait may be before those of us with unlocked bootloaders and rooted Xplays are able to get this in a ftf or update.zip format to flash manually? I am liking the 720p camera and of course the auto brightness option.
Or if someone knows if its a pain in the ass to create one of the above? I am sure that in order for any of this to happen someone would have to gain root access and then flash a recovery to do a complete backup, then piece it together and or convert it to one of the above formats.
Are you sure 2.3.4 is out for Verizon?
2.3.3 came out like 5 days ago.....
sorry, your right. I meant 2.3.3. By the way, would it be possible to flash a 2.3.4 ROM from the UK and then just flash the CDMA files from Frasertags ROM?
Do we know what the changelog is or the Verizon update? I cannot find it anywhere.....
Also, I now its the wrong thread but if I relock my phones bootloader and relfash stock ROM so I am unrooted, and I flashed the new 2.3.3 ROM, if I wanted to unlock the bootloader then would it be the same key I used to unlock the first time?

Sorry I run my phone stock not sure if any of that will work.
As for the changes, there is no changelog but there is another thread I think in Q&A where everyone has been documenting changes. 720P video recording is not one of them.
The major ones: better autobrightness and a way to disable it and Media Server (awesome feature, stream stuff from your phone wirelessly to any DLNA device).
Thanks Rogue, I found the thread about the changelog stuff..... where people are posting there findings. The 720p is from 2.3.4.
To answer earlier questions: If you re-lock your bootloader you _SHOULD_ be able to safely apply the OTA (or a flash file) and then re-unlock using the same code. However, I would probably try to do it via SEUS instead of the OTA. That way you can have the files ready just in case you need to unbrick and re-do it. There are unbrick from bad OTA threads around in case you booger the thing.
I wonder if somebody who hasn't unlocked could use SEUS (SonyEricsson Updater Service software) and download a copy of the flash and post it up for us. I imagine the Devs would like to have it, as well as the general unlocked community. I saw what looked like a link to a .IMG file over in the dev section that somebody was claiming was the R800x 2.3.3 (the new OTA) but I haven't verified it yet.

[attn] root and unlock your 4.4.2 xt926 now!

Hey, go ahead and take the OTA now, and do it NOW because another OTA is on the way that will definitely remove the root exploit which means unlocking your bootloader will be gone.
As SamuriHL and LifeAsDroid have mentioned in other threads, THIS IS A GIFT FROM THE MOTO GODS (an inadvertent gift that wasn't meant to be given to you, but it has been), so PLEASE take it NOW and use it, abuse it, whatever.
BTW, if you're worried about warranty, you already will void it once you root and they have a root checker built in, so they CAN tell if you rooted or not, so if you're going to root, you might as well unlock the bootloader too.
So, go here to root AND unlock your phone. SamuriHL has been keeping new findings up-to-date with this thread, so do it now:
http://www.droidrzr.com/index.php/topic/46155-rootunlock-razr-hdm-build-183-kitkat-towel-root/
Get Towelroot and the latest Motopocalypse files from SamuriHL and unlock your bootloader. Do this NOW because I just received an email today about another upcoming soak test, which means, root WILL be lost (Towelroot only works on kernels dated before June 3rd, 2014) which also means, once you lose root, you cannot use Motopocalypse to unlock your phone AND they'll probably re-patch the unlock exploit again.
So, do it now or forever hold your peace.

I am waiting for CM, not yet unlocked/rooted: Do I update to B27?

I basically am holding out switching my daily driver to the Axon 7 until we have a fully functional CM or other clean ROM with root capability. My Axon 7 is on B20, and I got the update notification. Any reason I should avoid going to B27?
My concern is that we've found an unlock workaround for B20 but I am not clear if it works on B27, and I don't think ZTE has re-opened unlocking after the B27 update. So is updating a big risk that I won't be able to unlock/install CM when it is feature-functional?
I'll be very simple and easy answer.
Yes , Unlock Bootloader with know method base on B20 and you'll still be able to get goodies

I am sorry, I am interested too in this topics and I do not understand well.
If I unlock the bootloader on the B20 and root the phone, can I simply update the smartphone at the B27 (and others) with the ZTE OTA updates without brick the phone or lost the unlock bootloader?
Thanks
Edit: I found the asnwer in an other topic, I am sorry.

No problem, in your case just unlock bootloader and get the update.
No need to root till you are B27.

Oh, of course you can UPDATE. You just can't do it via a "real" OTA : you have to go here, get the files, apply modded updates via sdcard.

What about receiving OTAs on rooted devices that haven't unlocked the bootloader?
I'm on B27 and I've been waiting for some progress before unlocking or rooting due to the plethora of issues reported like broken wifi, or camera, etc, but I'm getting tired of BS that could be dealt with if I had root such as the insufferable YouTube ads. I'm not going to watch an unskippable 30 second ad for a 2 minute video. I looked into it and the process of simply rooting it seems pretty convoluted (requiring drivers, flashing multiple things, etc) and some parts are ambiguous. For example there was no specific instructions, on the guide I was looking at, about how to install TWRP which I want to see stated clearly since again there are reports of people screwing up their phones simply trying to install that.
I'm kind of surprised there isn't an all-encompassing sticky with links to every possible issue and how to resolve them and I'm sitting here wondering if there's every going to be solid support for this device with easy root/unlock/recovery/updates like other flagships have.

About B27 and Cyanogen
- From what I've read, you still have to downgrade to B20 to unlock/root/twrp then update to B27 using modified files.
- Once you got TWRP, you have several options to restore your phone in case of problems (despite full stock firmwares being limited to EU models - officially)
- From the actual state of Cyanogen, to me, you're better off unlocking+rooting and using xposed than installing CM
- Unfortunately, the systemless root isn't compatible with Xposed (and likely will never be) so you don't have a "temporary" solution
- Think about us poor A2016G users in europe
About Root+OTA's
- If you have systemless Root, you can have the OTAs, but it will wipe the root...
About TWRP, if I remember correctly there is one requirement:
- Being unlocked (Guide here)
- Installing it (Guide here)
I am, myself, waiting for a repartition tool, because 14GB being used by system is making my eyes roll so hard I'm getting motion sickness. A stock MM build is 400MB today, and I can't believe there is 13.5GB worth of camera and wallpapers in here (so, wasted space)
- We can dream it's here for the Nougat Dual Boot system, but even then, 14GB !!!

Nope. I used the official ZTE OTA update that I grabbed from ZTE servers myself. I did not use any sort of modified update. Yes, I did sideload it via sdcard, but that was because I didn't want to bother connecting to the network. I used ZTE's official update and applied it through the stock recovery fine.

See above. Did not have to use modified to update from stock B20 (with unlocked bootloader) to stock B27 (still with unlocked bootloader).
I am interested in this post as I am in the same boot. I am kind of waiting for stock firmwares before I start messing around because things have gone wrong it the past that only a fresh install have fixed. I am good with my current build and am just missing xposed and all the ad block features.

My bad, I just assumed that unlocked meant modified recovery with TWRP (and in that situation, it seems OTA won't work). "Just" unlocking the bootloader with everything else stock is usually rare.

It makes sense to me the option is grey out since you unlocked the phone with chimera tool instead of HTCDev. Also one doesn't need to relock the bootloader for OTA, i.e. simply unlocking the bootloader doesn't affect OTA.
Come to think about it I haven't heard of an update for 128G, the 1.15 is for 64G. I could be missing something though.
