[Q] (Q) Would installing a custom rom lock my network? - General Questions and Answers

(Q) - Hi guys. I wanted to know that if you install a Custom rom on a rooted device, Samsung Galaxy SII i777 (AT&T) in my case, will it lock my network? I reside outside of the US and bought this phone in unlocked condition. A timely reply will he appreciated!

No. Simlock block is not written on normal rom/firmware flashing with cwm/flashtool/fastboot flash. It must be flashed separately to be over-written.

So in simpler terms, i can install a custom rom without getting worried about the network lock?
Thanks!

Yes, network lock/relock is excluded on normal flash.

Thanks again! What stable/normal Roms do you personally recommend for an SGH i777?

[Q] D2G not asking for unlock code

Hi
I bought D2G from ebay it was listed with bad esn.It's not asking unlock code or anything, reads the sim card, changes to global mode, connects to a network(jumps from one to another all the time) but no service when I try to dial a number says network not available. So what is wrong with my phone? is it unlock?something is wrong wit the radio? or what?
If it is not asking for network subsidy code, then it must be unlocked if it works with your sim. Make sure it is set to GSM/UMTS mode, not Global - if your sim is active you should get reception. At least on 2G (GSM). If you are not getting reception, something might be wrong with the phone.
It might also be running a custom ROM (unlock requests only work on Blurry ROMs afaik); another possibility is former owner going to the “hidden” menu and choosing “USA Band”.
In the latter case, you need to SBF.
thanks Gasai Yuno custom rom was the problem now it's on stock rom and is asking for unlock code. I'll try to unlock it thanks again

Good catch! I wouldn't thought somebody would sell their phone without bringing it factory default first..
Good luck to OP with the unlock codes - hopefully your phone won't turn out to be from those Verizon played with..

Ask much as I understand. it stop asking for unlock code because of Custom Rom. I have the same problem. What should I do to be able to enter unlock code with Custom Rom?

Flash the stock ROM.
I try to flash stock rom (kdz extension) but it doesn't work because my boot recovery is not stock recovery. What should I do to remove CWM recovery for my phone model LG Optimus G E973?

Please create an backup of your Rom using CWM and then you can try to update/flash your phone.. If your phone is locked again, put your backup back in and search for an patch for multilanguage with arabic support..

NO, the phone will NEVER be locked again
SIM LOCK is more like a hardware based security, not software.
you can flash stock safe

after you unlock the sim, you have to flash custom recovery and then root
then you can flash custom rom through recovery
BTW, its possible the phone can be lock again only if he unlocked the sim via root exploit
if he used an IMEI calculator, yes it is ok

at this point, your phone is not unlocked via root exploit
so you can do whatever you want, it will not lock
and the unlock being part of hardware, it will never lock back unless you want it to happen

he flashed stock rom as the method of calculating the unlock code based on imei is valid for this phone on 2,3,6
he could do this on kk risking to not work and losing the money
maybe he thinks the code resets the bootloader which happens on devices such as htc
but i have here a clear example:
if you use the yellow triangle away app from chainfire and you flash another rom, does the yellow triangle appears again?
i guess you know what is triangle away, search it on google if you dont
and the triangle thing is a hardware code, so is the sim lock
Hope i helped you!

Not without unlocking the device, which can't be done on the verizon s6.

I'm not talking about root. I'm talking about unlocking the bootloader so you can flash modified kernels and what not.

Ok. SO how do i know if it´s unlocked? Because i bought this s6 used....
The problem is the Verizon S6 family is currently unable to have modified bootloader files as no one has found a way to change them with or without tripping Knox, the security suite on our phones. Hell, everything updated past Firmware update OF1 isn't even rooted yet and no one is sure when or if we will even have one. Basically what I'm saying is, there is no way for you to get the international ROM onto your phone unless you just happened to either crack the system yourself or the person you got it from managed to find a way without telling the world about it.
Word of advice, you can have a phone that is rooted with a flashed ROM but still have a locked bootloader. In our case it was due to an exploit that was patched.

Looking to buy the Galaxy S7; couple questions

Hello,
I'm planning to buy this (Exynos) variant of the Galaxy S7. It has great specs and the availability of custom ROMs pleasantly surprised me. Therefore, I have some questions:
1. How do you go from full stock to being able to flash custom ROMs? Is it difficult to unlock the bootloader? I'm used to Nexus devices where you'd reboot to bootloader, fastboot oem/flashing unlock and that's it, but the procedure is certainly different on the Galaxy S7.
2. Are there any things I should be aware of? e.g. Can I brick my phone with flashing something or doing something that wouldn't brick some other phones?
3. Is it possible to return from custom ROMs to full stock? I guess I won't have KNOX back since that's a physical detail AFAIK, but I can live with it, I guess. Modded stock ROMs can also be flashed from TWRP, right?
4. I was really surprised that the Exynos variant got so much dev support. Normally I would expect that from a Snapdragon device, but the Snapdragon variant's BL is locked. How come Exynos got so much dev support and ROMs with practically no issues on this device (and some other like the Galaxy S6)? From what I've heard in the past, the Exynos phones aren't exactly the most dev-friendly ones. What has changed since? I may be completely wrong though
That's all for now.
Thanks in advance!

You need to flash TWRP custom recovery (Instructions in the TWRP thread)
Unlocking the bootloader is a simple toggle switch in developer options

Always a risk, make sure to read up thoroughly before flashing anything

Once KNOX is tripped that's permanent, but you can return to stock using ODIN and a stock ROM from sammobile or other sources scattered around the forum

So, to unlock the bootloader, I literally have to toggle "Enable OEM unlock" in developer options? That's it? I'll have this switch regardless if I'm on Marshmallow or Nougat, right?

Correct
Don't make the same mistake a few members have, and disabled it once they had TWRP installed, you need to leave it unlocked while you are running custom

I've never wanted to try this, but I'm curious. What happens if you toggle it back? Bricks the phone?

It gets stuck trying to boot with custom binary blocked errors iirc
Then you need to spend time working out how to bypass the lock and reflash stock etc
If i was you then i would keep the s7 with the stock rom because this stock rom is pretty awesome and i like having the secure folder functions etc.
