Hello everyone,
I'm a long-time member but seldom poster; owned several Samsung/Android devices in the past and rooted/installed custom ROMs in all of them, so I'm a not a newbie, have read the FAQs, searched, etc. I just got an I337M on my Fido renewal and was somewhat overwhelmed by warnings about requiring different approaches to rooting depending on the basebands, etc. Anyway, I have a couple of questions I did not find adequately answered and I hope you guys would be so kind to help.
In the course of composing this post, I took the plunge to root using CF-Auto-Root and install TWRP 2.8.3.0 - I guess Knox is now tripped and the warranty on my week-old phone is gone - oh well. Next on the agenda is to:
1) Unlock my phone;
2) Try to improve cell reception with a different modem (I have noticed I seldom have more than 2-3 bars while I have 2 other different devices in the same room on Koodo with full signal strength);
3) Flash @Danvdh's awesome 5.0.1 Lollipop GPE ROM.
My questions:
1) To unlock, it seems I have to downgrade to 4.2.2. first. @veryluckyguy suggests to get the MDJ ROM and only extract/flash the modem.bin and follow the rest of the instructions. Does the modem.bin get flashed over with any new complete ROM I flash or are they separate things? Will I lose the unlock when I flash a new ROM?
2) Are modems generally interchangeable across Android versions? For example, can I flash a 4.x modem in 5.0?
3) Anyone have experiences with poor reception on Fido/Rogers and solve it by flashing in different modem? If so, which?
Thanks for all help.
Like you I was on Fido and switched
1) To unlock I simply used online service for SIM unlocking. Cost $20
2) I am using a 4.x modem in 5.0.1 GPE ROM
3) I cannot answer your 3rd question as I simply switched service.
Hope this helps
I'd recommend you to not try any software related unlocking methods, they tend to give problems with some sim cards lately. requesting an unlock code with your imei is the best and safest way to unlock.
Thanks for the advice guys. Part of my wanting to do this was as a learning and tinkering experience. I could take my car to a garage to have it repaired or hire someone to do home reno work, but like most members of the site we are tinkerers. I don't have an immediate need to unlock my phone, so I'll wait for now until I have more time and maybe unlocking procedures/tools become more mature and robust. I'm happy that my phone is now rooted, TWRP'ed and 5.0.1 GPE'ed without having bricked it .
I'm still going to try to flash a different modem to try to get better reception.
Thanks to all the amazing help here!

If you're still willing to unlock, consider flashing stock MDJ, rooting, then unlocking with RegionlockAway. From there, you can work your way back up to GPE 5.0.1 and the unlock will remain. I'm my experience, modems can be Odin flashed across Android versions, but compatibility discrepancies may subject the device to overall instability (ie. bootloops etc). I have found though that the modem from stock NC1 allows for Rogers LTE in 5.0.1.
Long story short, I was in a similar boat, but thanks to the help and advice from the members and contributors on this forum, I managed to find the solution. Here is a step-by-step. Good luck

Hello all,
I just inherited a Samsung GT-S5360L phone from my father and i wanted to try some roms. Some of the available roms seem pretty cool, but i have noticed a small detail, my phone model ends with an L, and the roms available dont.
This is probably because my cellphone is a southamerican model. So, My main question is, what should i check before flashing a rom into my S5360L in order to avoid problems?
I am mainly worried about loosing the 3G signal (or the whole phone signal) if i flash an incorrect rom. I read some posts that said that i should use a specic CSC.
Can anyone explain to me a litle more about this? Do i need to flash the ROM and my original CSC files in order for the rom to work with my operators, or the process is different?
Thanks in advance.
Solution!
Sir,
You must have bought your Galaxy Y with some Carrier! That why it end with a "L", But that does not matter! To prevent bricking ur phone just follow the correct installation instruction.. If you brick your GY there is a guide in the general section to restore back! Make a Nandroid Backup first of all and then Flash GT-S5360 Firmware (The one preferred in the Rom's installation guide I hope this helps! As much as I know, all roms will work :laugh::fingers-crossed:
Best Regards,
ArnavGosain

to ensure installation success please download "Galaxy Toolbox" by doky in the playstore and unlock your network (if it is sim/carrier locked)
then follow all instructions provided by the rom authors to ensure success,
if in case all else fails just reflash to a stock rom via odin, not to worry since any stock rom will do
thanks for the information guys. I know any rom should work, i do it in mi LG Optimus2x but i had a samsung phone before (galaxy spica) and i had some troubles after flashing some custom roms, where i would only be able to have 2G signal and not 3G, or in some cases have no connectivity at all. I will give some roms a try and see how everyhting goes (and do a backup first, hehehe).
thanks again.
Hey everyone,
Please bare with me, this is my first time rooting & flashing a smartphone, so my knowledge on the topic is still limited even after some reads.
I also have the "misfortune" to not fall into the (apparent) easier route of having a non-Canadian Galaxy S4 where the model starts with "i950.." but mine being SGM-i337m. From what I've understood, the only reliable method I could use would be CF-Root, as described in this thread (OP's post), although the thing that bugs me, because I'd like to be able to install whatever ROM I'd like, is the line that says "[..] and those who want to keep as close to stock as possible. CF-Root is meant to be used in combination with stock Samsung firmwares [..]".
Also, which might be worth mentioning, my best bet is I'll probably end up flashing Cyanogenmod's ROM and they seem to have packaged installers, but I'm still worried it might not cover my model (if I take that route instead of rooting using CF-Root). From CGM's wiki under Supported Devices, there's a list that includes "jfltecan" (code name) for Canada, but I'm still hesitant. Do you guys think it covers Koodo (service provider) which I believe is owned by Telus (another SP) ? The last thing I want to do is brick my phone or have it unusable at the booting stage or whatever. And I don't mind reading, so any helpful links which covers this specifically would much be appreciated, although I don't mind an all cooked answer
Thanks
Hey XDA I have rooted and installed custom roms on various android devices in the past, and am now working on my Note 4.
I have it rooted and TWRP installed , but am now unsure if I need to flash a different modem or bootloader. I understand that the Canadian variant uses the T-Mobile Roms.
I am looking to install CMRemix http://forum.xda-developers.com/note-4-tmobile/development/rom-cmremix-rom-v2-5-12-23-14-t2981479 which is a T-Mobile Rom.
Will I simply download and flash it or do I need to do extra work first?
Thank you, and I apologize for posting this question. I was slowly going crazy after searching the forum for these things to no avail!
I figured it out. I checked by bootloader and it was up to date. I was having issues with Odin, but after reconnecting the USB cable 6 different times it finally picked up my phone in Downloading mode!
No worries. It seems that the N910W8 is basically the same hardware as the N910T3.
In the same way the Note 3 T-Mobile was the same as the Note 3 Canadian variant.
No need to worry about modems assuming yours is up to date.
Although, I must admit that while CM Roms tend to have interesting features, they lack support for some of the built-in hardware, and the battery life has been inferior in my own experience.
You should check out Temasek's CM versions.
Have fun
All,
Apologies in advance if this has been answered (I think it has, but I am being cautious here). I've seen a couple of posts that seem to indicate that this is indeed possible and relatively easy. Wanted to see if I could get confirmation before attempting this (seems too easy).
Full disclosure: this phone is not rooted. It is unlocked and I'm currently using it with a t-mobile sim, but the sprint activation app continues to cause problems and requires it to be force closed. I'm also now having sporadic issues with LTE connection. Double checked all settings with regard to t-mobile configuration already. Thinking this might be the best way to go at this point. I'm not interested in rooting/unlocking the bootloader unless absolutely necessary to do this.
Based on my research, it would seem that I could simply download Odin 3.12.3 (https://forum.xda-developers.com/showthread.php?t=2711451).
Then, use that to flash the flash the files found here https://forum.xda-developers.com/tm...o/g930tuvs4bqc1-odin-files-3-25-2017-t3579177.
Any guidance would be greatly appreciated. Thanks in advance!
Anyone have any suggestions?
Thanks.
Anyone? Don't all speak at once.
Thanks.
If it is unlocked, odin the tmobile firmware. It will unlock the correct bands. You can also flash the universal firmware and get the same thing without the bloat
Im having the same issue. Another thread suggests the universal version then flashing something else to open the bands we need. Those 5 download links you shared, are those all tmobile stock? Ya id love a tutorial lol
I decided to try this today using the files I originally linked and everything appears to be working just fine.
Thank you, lvpre, for the reply.
Hello guys, I'm posting this for first time.
My girlfriend is having a Samsung S5 from AT&T and I want to root it as she told me system apps from AT&T are taking too much space on her phone and so I was thinking can I flash any custom rom on it?
As I see the AT&T thread separate, I want to ask some things
Does Network provider has to do something with it ?
I can flash custom rom on her phone or not?
And same odin thing works ? Like unlocking bootloader and fishing custom recovery
I have never rooted any Samsung phone ever
I'm having a oneplus and HTC.
If anyone can tell me what all do I need to do, I would appreciate it a lot .
Att version has locked bootloader .... Root is possible and there a few roms but they are all based off the stock rom just tweaked a bit ...

You should consider two things:
1. ATT phone may be sim-locked (locked to their network), but it has nothing to do with custom firmware. This problem may be solved more or less easily.
2. ATT phone (SM-G900A) does have a locked bootloader. This is a real problem.
That's why you're limited to touchwiz-based ROMs and stock kernels.
This means, in it's turn, that you cannot have root on 6.0 and above, you cannot have custom recovery, LOS, etc.
If it was my device and I was going to use it as a smartphone (to communicate with others) on a GSM network, I'd install this ROM in unrooted variant and the latest firmware (boot, modem, kernel).

It's been over 2 years for her phone, unlocking bootloader won't be an issue ( we can unlock it right?) . And she will be using AT&T only because she is using family plan.
If you dare saying the real problem is locked bootloader then we can just unlock it , or I understood it wrong

I believe that the following thread may help you out with this. It's S5 AT&T device specific.
