Okay so I've been having an SGS3 with me lying around, but always love using it. It has TWRP on it and uses the app HIapn global so I could use T-Mobile on it. But I've been wondering, if I Install CM 12 on it will it erase the apns and not be unlocked? Because I can't stand touchwiz in anyway. Its on 4.1.2 with TWRP on it, Sch- I535. Will the phone also be bricked in any sort of way, because I've heard the new boot loader on the s3 makes it impossible to install a custom ROM. If anyone could help asap, it will be appreciated . :good: I just don't want my T-Mobile service gone Edit: service is now working fine, except every rom i install, I get no incoming calls? Any ideas? Roms I installed Mastamoon Cm11, Mastamoon Cm 12, LS Lollipop, Bliss 4.4, and Cm 11 by Invisiblek . Could it have anything to do with the baseband/modem version?
Guys, I got the OTA to android 5.0.2 about a week back, but I'm tired of the poor performance. Nova 3 is now unplayable at parts where transparency is used. So, I was thinking to revert back to KitKat 4.4.4.
>>Will the performance improve after the next update, i.e., 5.1??<<
The dilemma I'm facing now, is to whether flash back to stock KitKat 4.4.4, or to flash cyanogenmod 11 using cwm recovery. I also want to know which one of the two will be easier and less problematic.
Thank you.

OK, problem solved.
I installed cm11 using philz recovery. Now, the phone is blazing fast!
Did not downgrade to stock 4.4.4. Instead to cm11 4.4.4.
i had upgraded my mexi-maxx to lollipop a few months ago and could no longer stand it. outside of being picky with my phone, the GPS didn't work as I had hoped.
i reverted back to kitkat by means of a TWRP backup I had. Had some issues with doing so. some of my images would not work, but a stock on of KK did. could not use any of @ChazzMatt images either; nor factory images as RSD pinged a FAIL. started getting worried, but just about all good now.
the phone now boots directly to bootloader mode and i have to choose 'start' to boot into system.
is there a way to change this? thanks all.
You can try Brazil 22.34.16 lollipop build, it is the most stable 5.0.2 for moto maxx / turbo atm. Your issue is caused by the incompability with the lollipop bootloader and 4.4 kitkat twrp image. Take a copy of your nandroid backup to your pc and flash 4.4.4 images except gpt.bin.
http://forum.xda-developers.com/droid-turbo/help/tutorial-how-to-flash-official-firmware-t3074724 ( following 5.step )
Then flash twrp recovery and restore your 4.4.4 nandroid, it will be fine this time.

Thanks. really dislike LP as a whole. are there advantages i'm not seeing? battery was the same, wasn't really faster, GPS terrible (used stock rooted and CM12.1)
want to make sure I understand what i'm doing. according to thread you linked to (thank you btw I could not find that earlier too busy freaking out) because i took the LP OTA i have the upgraded LP bootloader, but I do not need to downgrade it to go back to KK? meaning LP BL is backwards compatible?

You need to downgrade to 4.4.4 with stock images except gpt.bin or else, it is normal having issues like you're facing. Lollipop bootloader is meant to work on lollipop system. Anyway, just flash 4.4.4 full images with mfastboot except gpt.bin, then flash your twrp recovery and restore your kitkat nandroid. It will be fine.
I downgraded my xt1225 back in time with the same tutorial and it works fine.
this works perfectly. old twrps work again.
trying to the india version of LP as some are saying its vetter, installed and then put cm12.1 back on. gonna give it a week or so and see if GPS locks better. if not, back to kitkat. thanks for the help.

India firmware is as bogus as a software can get and they didn't deploy patch ota's to fix its issues. Your best stock lolipop bet is brazil 5.0.2

bogus as in not official or bogus as in crap sw&support? again, no interest in using stock LP. cm12.1 fits all my needs except the double swipe to pattern unlock, which from what i read i'm stuck with.
at this point i'm only interested in the best driver set for the phone. interested in getting better GPS lock and hopefully better reception at work, in the middle of a giant metal building (kitkat worked much better IMO WRT to reception and LTE/HSPA+ handover)

If you were just running stock LP -- which you say you do not want to do -- then @Semseddin is correct that Brazil and Mexico factory images are better than India. Just because they both have newer updates India was never given.
In my images thread you can see,
Brazil: QUARK_RETBR_5.0.2_LXG22.33-12.13_cid12_subsidy-DEFAULT_CFC.xml.zip
vs
India: QUARK_RETEU_INDIA_5.0.2_LXG22.33-12.11_cid7_subsidy-DEFAULT_CFC.xml.zip
Then, @Jaocagomez has an OTA which takes it to:
OTA to 22.34.16 Brasil Retail Stock Lollipop 5.0.2 /// Blur_Version.22.34.16.quark_retbr.retbr.en.BR.zip
But CM12.1 beats all that by having 5.1.1.
Yes, CM 12.1 (5.1.1) is still using the stock 5.0.2 kernel source -- because Motorola has not yet released 5.1 kernel source they gave to the XT1254 Droid Turbo back at the beginning of July. But it's still 5.1.1 with 5.02 kernel source, NOT 5.0.2. with 5.02 kernel source. It's a vast improvement! Stock 5.0.2 was too laggy for me.
So, for me running CM12.1 (or another 5.1.1 custom ROM) gives me the best of both worlds. I have the latest kernel source/radio that Motorola has released for our phones, while still having 5.1.1.

Now having said all that, my wife and I have two XT1225.
I flashed both to India LP 5.0.2, then flashed CM.
I also re-flashed the India radio and bootloader (5.0.2) found in the CM12.1 op post just to make sure.
I have no problem with GPS. I use GPS every day. But I use TopNTP. See this post:

The only issues I have with CM12.1 is my phone seems to lock on to HSPA when leaving Wi-Fi network even though there are strong LTE signals around -- and even though I have "LTE Preferred" chosen. As I drive it will eventually move from HSPA to LTE, but takes like 15-20 minutes.
If I stop the car, remove and put back in the SIM card 2 or 3 times, then it finally locks onto LTE network that was there all along!
It was a change CM made to APNs/telephony back end of July that seems to cause this. (I kept my wife's phone on the July 29 nightly. We will be in the car, she will have LTE and I will have HSPA. Arghhh.)
But I put up with it, and keep flashing new nightlies -- hoping it will be fixed -- and also because other than that CM12.1 is very smooth and much better than stock 5.0.2. I don't want to flash my phone back to July 29 nightly. I still have it -- but I would have to wipe my phone completely and reinstall for it to work. I already tried just flashing that older nightly over a newer one and I got boot loops. I restored latest back up from recovery and haven't bothered since.
Fixed this issue. See here:

I recently purchased a D800 G2 off eBay, so I haven't the foggiest of this phone's history. When I got it, the stock firmware was pretty broken (Play Store not working, UID errors, ETC), so naturally I didn't hesitate to root and load TWRP via AutoRec (and subsequently updated to the latest unofficial TWRP). Unfortunately, once I flashed the latest snapshot build of CM13 (official), things took a turn for the weird. WiFi and cellular data will shut off sporadically--even at moments, leaving me internetless for 5-10 minutes--and this applies to all other snapshot builds of CM13. It will not turn back on manually; only time and patience can do that. Only on CM12.1 official or unofficial builds would internet hold.
I was wondering how I should approach this. My plan was to flash a KK tot and update the last LP firmware OTA; root with either OneClick or KingRoot; install recovery via AutoRec and bump update to unofficial TWRP 3.0.0.2; and finish with the latest official snapshot of CM13. I just wanted to make sure I'm going about this the right way or if CM13 isn't a good fit for the D800 variant of the G2. Any help is appreciated!
