flashing stock firmware and ROM

chemotkbilo · Apr 20, 2014

Hello Everyone,
I am a new Android User, switched from Blackberry (had to use it for work for many reasons, employer requirement) . i have searched the forum for possible existing answer, could not find any.

i have just bought G2 At&t (D800) version from a previous owner, and it is unlocked by the previous owner. i have already rooted my device with custom recovery, it is Stock ROM 4.2.2 and software version 10o

my main two questions,
Q1 : if i flashed and upgraded to 4.4.2 using either D80220a - KOT49I or recovery friendly D80020c method, will that lock my unlocked phone? (i am using it on tmobile)

Q2 : is there is a significant difference between using D8022a and D80010d boot loader mentioned in kk upgrades candidates.

p.s. Since i am a new android user, but with enough backgrounds to be a developer. i will be starting to work on porting M8 sense 6 and contribute To the LG G2 Community. finally have jumped into the bandwagon hahaha. took me a long time lol ..

cheers

I don't mind taking risks, my only main concern, will upgrading to stock based kitkat ROM and firmware lock my GSM again and be usable with AT&T ONLY. that is my main concern in the first question.
i know for a fact, that firmware originally is installed by the service provider and is separate from the locking mechanism. Most phones can be unbranded by reflashing a different firmware version. however, i am seeking reassurance from experts to confirm such knowledge

thank you

If you are gonna flash kk I suggest you first downgrade to 10d and use Gary's method or upgrade via tot and then root/install custom recovery but I cannot assure that it will remained unlock as I have not encountered many people who unlock and flash custom roms

I see, i guess i will take the risk and re-update here. but will it matter a lot in term of FUNCTIONALITY. using international (AndroidUser00110001- power user edition) vs garyd9 method, excluding the removal of bloatware.

thanks

Well using androiduser's Rom is nice because of less bloat plus no ciq but I myself would not flash a Rom that changes the model number from d800 to d802 just because if it soft bricks it will be harder to restore via flash tool, which is why I opted and am a current user of Gary's Rom but I debloated it
