I have an LG Optimus One and custom ROMs can't get any easier. It's just root with z4root, install Clockwork recovery with ROM Manager and flash away. I'm not yet familiar with the other aspects of rooting and installing. So I ask how easy is it on this device? I might pick one up soon since it seems to be getting cheaper and cheaper...
It's really simple. Same app to root, then use the Odin program to flash while in download mode. Instructions here.
I'm still a beginner when it comes to Modding and this was a cakewalk.
Sent from my GT-P1000 using XDA
Ok sounds good. But what does GSM and CDMA mean? How would you know what kind of Tab you got (I'm assuming these are hardware related since the roms have only one or the other)? And what does the modem have to do with anything?
I didn't have these terms involved with my O1 so I'm not sure yet what they do... At least I know to avoid the Wifi only p1010 since it isnt as developed for (really important to me).
gsm/cdma is about cellular networks, if you have a simcard slot then your a gsm, cdma is without one, the service company can provide you service without one, its mostly a USA thing, sprint, verizon etc, not sure about Europe,
look at the back of your tab and tell us your model no. i have a p1000t, but this tread states you have a p1000 so i assume you have a gsm one.
sorry if its not too informative.
Practice makes Perfect
All custom ROM providers these days seem to suggest you follow the Overcome Guide. This guide was the one I followed to start with and it is very clear. Go to the teamovercome.net website and look at the guide.
I can do this now from memory, and have used the same method to flash ICS, Hyperdroid, and Overcome.
It's a great guide - flash and enjoy!
Hello,
as I am completely new to Samsung, I have got a question regarding the different basebands.
My S4 is running XXUAME2. New custom Roms are using different versions (for example XXUBMF4). and what is a CSC?
I couldn't find information if it is important to stay at the same baseband version, wher the differences between the basebands ar.
Can anybody please explain me?
Thank you!

I would also love to get the answer to this question +1
Thanks
Basebands are the same as the radio. They can improve your signal, and i some cases even affect other things like camera quality.
Newer basebands are nearly always better.
CSC is country code and you should try to find a code with your country
makhakz correct me if im wrong but csc's and modems are two different things altogether. my advice would be to leave csc alone as its allready set for you and just flash a different modem.
some modems may increase speed and connectivity others may improve these.
its a case of trial and error really as to which one works best for you
I have a few general questions I hope some people can answer to help me understand these topics better, numbered it for ease of replying.
1) For unlocked stock firmwares, what is the point of Samsung having multiple firmware files for different countries/regions? If you go to sammobile's website, you can see what I mean. I understand having different firmwares for different providers as they have their own bloatware/branding. But unless the unlocked firmware files contain different languages for different countries/regions, what is the reason for multiple unlocked firmwares? Gets confusing when choosing a firmware to flash your unlocked device (if I should choose UK or Germany, for example - and I'm sure both would contain the English and German languages anyway).
2) Is region locking now a non-issue ever since CF's region lock away solution? I'm assuming if I had an unlocked phone with original firmware that was not region-locked, that I shouldn't have to worry about upgrading to another unlocked firmware (that does contain region-locking) since CF's solution works? Or should I be worried about upgrading into a firmware that does have region locking?
3) Do all firmwares that contain Knox have the potential efuse trigger? And if so, what actions trigger that efuse? I gather from reading the forums that normal rooting triggers it (the DLV method excepted). But what if I wanted to flash my unlocked device with another stock firmware from another region (because I liked that firmware better) - would that trigger the efuse as well? Any other conditions/activities that would trigger the efuse?
Thanks in advance for helping me out with these n00bish questions.:good:
Anyone want to take a crack at these questions? Thanks!

1. The different firmwares have variations on carrier specific bloatware and/or regional basebands that could impact your connection, although in reality, I've never had any problem using other modems on various Samsung devices in my region. This tends to vary quite a bit by region, so sometimes it matters, othertimes, it does not.
The general rule is to stick with your region if possible, but otherwise, if you want to avoid bloat, any firmware is possible as long as you make sure it's for your specific variant. That's the biggest caveat.
2. CF Region unlocking only works for the 9005, so Exynos based International models are not supported. Ony time will tell how long the exploit CF has found will actually be viable in future firmware updates. Things could change overnight.
3. Firmware versions beginning with J3 and above have the Knox bootloader, as far as anyone can tell at this point. I used to care about the Knox trigger, and it really pissed me off with the S4, but I've come to accept it as a price one must pay. In reality, all major players are working toward this "safety" goal. LG has their own version of a locked bootloader, etc. What triggers the Knox eFuse is custom ROM/Kernel/Recovery. Rooting alone isn't really enough to do it.

Not bloatware no, more carrier information, APN - http homepage/email set up etc. Unless it is a carrier's firmware rather than an unbranded firmware (unlocked)

Agreed. But you can install another region firmware if you wanted faster updates, or an update which is region specific

Right. I just meant to say that some firmwares are carrier firmware and others are open and tend to have less carrier branding and bloat in them.
Wow thanks guys for your detailed replies, much appreciated.
1) Yea, regarding the multiple firmware choices, I understand the need for separate firmware files depending on carrier-specific requirements. However, for a specific model of an unlocked/unbranded phone (say, the GT-I9505), the hardware should be identical regardless of where it's originally sold in the world. So it looks like the only reason for having multiple firmware files for say an unlocked GT-I9505 would be to include different languages. Why not just have one firmware file for a given unlocked phone and just include all languages? Unless I'm missing something here. A little confusing when I go to download a firmware file for my unlocked phone and have to wonder which choice contains the "best" upgrades.
2) So from what you say, as of right now, the N9005 version of the Note 3 is susceptible to CF's region lock away solution, which is great. Is this also true for all other Snapdragon-equipped models like the Galaxy S4?
3) So the Knox efuse becomes an issue only if you seek warranty work, correct? It doesn't actually hinder or restrict your ability to mod the phone even after the efuse is triggered?

Yup different languages and region specific updates (Poland tend to update before UK for example)

It seems it works yes, a few conflicting reports, but 9 out of 10 seem to be ok, as for other models I'm not sure

Well yes and No.
Samsung are honouring some warranty work with 0x1 and sometimes they are not.
As for things working correctly, once tripped to 0x1 you cannot use KNOX functions, encrypt your containers etc. - Possibly be one or two other things you can't use that may not have been found yet(?)
But no it doesn't restrict anything once triggered bar what I posted about.
Will ChainFire's Region Lock Away TRIP Knox...if rooted with Knox not tripped?.
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
These are guides for unlocking additional basebands on Qualcomm devices I want to try it on yotaphone 2 but I thought I would ask for advice first.
http://forum.xda-developers.com/showpost.php?p=56577252&postcount=455
http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269
That's would be really cool for our YD206! I always thought that the lack of some bands was physical, so it's not and they are present in the motherboard?
Have someone tried it?
I found something that might be useful to the OP: http://forum.xda-developers.com/google-nexus-5/general/radio-enable-lte-band-3-nexus-5-d820-t2928561
edit qcn file
It looks like only way to modify, add LTE bands is by modifying qcn files.
It is working procedure for Oneplus3, for example
https://forum.xda-developers.com/on...ck-additional-lte-bands-t3519563#post70099218
Does anyone can do that? To add band 17, for example? we can supply original qcn.
what are the risks? why all are asking and no one do something? OR we all need a guide special for YOTA
