Rogers E971 helper thread

Alright so the point of this thread is to help people with their LG Optimus G for Rogers Wireless in Canada, also known simply as E971
Here are the official specs:
from LG:
http://www.lg.com/ca_en/cell-phones/lg-LGE971-optimus-g
from Rogers:
http://www.rogers.com/web/link/wire...normal&productId_Detailed=OPTIMUSGBLK&N=52+11
The main difference from this phone and the E973 version is the 700/2600mhz LTE frequency for Rogers as opposed to 700/1700 for Bell/Telus/Sasktel
The 2600MHz LTE spectrum (2x20MHz band) is the frequency used for LTE that has the most bandwidth available making it the fastest LTE band. Typical download speeds experienced will range from 12 Mbps up to 40Mbps. -from the Roger's site
This means that LTE will not work with other LTE such as BELL or TELUS unless they roll out a 700/2600mhz network, Fido piggy backs on Rogers and *should* work
Here are some of the more important threads to have your phone rooted and have a unlocked bootloader, up to know i do not know of any custom roms available for the E971
Give these guys your thanks and donate if you can
You'll have to root first then unlock the bootloader
Root:
Bin4ry's Root MANY ANDROID
http://forum.xda-developers.com/showthread.php?t=1886460
(confirmed working on E97120D)
unlocked bootloader:
Team Codefire's Project FreeGee

https://play.google.com/store/apps/details?id=edu.shell.freegee_free (Free)
If you want to keep your root and unlocked Bootloader do not update to the latest OTA (E97110E_00), you will lose root permanatly and Bin4ry's methode will not work anymore the previous version is linked at the 2nd post (E97110D_00)
more info here:
http://forum.xda-developers.com/showthread.php?t=2053880
to disable the OTA app:
"Disable" via Settings > Apps > All > Software Update > Tap Disable.
or freeze with Titanium Backup "Software Update 3.1.0"
Removing carrierware (only do if you have v0.5+ of FreeGee and Root or else you'll get a the security error bootloop)
You'll also receive the Security error if you tinker with the Google Apps that come with this phone (ex, google movies, google books, etc)
remove or delete the .apk , freezing with Titanium works as well

This makes me even MORE glad I bought an E970 instead of the E971. The Rogers phone doesn't even support both THEIR OWN FREQUENCIES, because the AWS band would mean the phone could easily be used on Telus or Bell. So the E971 doesn't actually get better LTE coverage than Galaxy S2s or iPhone5s by offering both bands Rogers supports.
The E971 supports 2600 and 700, 700 being the main frequency for AT&T in the US which is shared with the E970 but not supported by ANY carrier in Canada until after the 700mhz spectrum auction which isn't for another YEAR. But with an E970 on Rogers I still get the AWS band , and it is ALSO usable on Bell or Telus!
So overall, the AT&T phone gives just as good coverage out of the box, and better options for changing carriers and roaming than either regular Canadian model.
**** you, Rogers.

Thank you! This is very helpful!

With all due respect, unless you plan on changing carriers, then the E971 does in fact have the fastest up/down speeds. 2600 is basically empty right now, like driving a Ferrari down an empty highway. Not many people buy a phone knowing they'll be switching carriers - I certainly don't.
On a separate note, anyone else get a little happy tingle inside everytime the LTE icon comes on?

as far as i know the optimus g specs from LG/Rogers say the phone uses 700/2600 bands, im sure rogers has 700/1700 AWS deployed as well for other lte capable phones,
well that would be my best guess

From what I've read Rogers has the standard AWS frequency LTE, but is also rolling out an additional 2600MHz network in addition to AWS, providing a nice empty spectrum and supposedly better coverage in rural areas. This is supposed to be in partnership with Bell, but Bell is apparently not supporting the frequency at this time. This lead to my issues with Bell LTE linked in the OP.
In theory, if you have 2600MHz coverage, you should be able to get better throughput due to the empty spectrum, but in practice (from my limited testing) you get generally the same speeds as any other Rogers LTE phone (such as the iPhone, which is not using 2600MHz).

Has anyone tried the Base 0.5 Rom over in the at&t optimus G forum. Just wondering if it would work for the E91.
If you have what are your results?

I think someone did flash it. They said it worked. I'm not sure how because I thought partitions were different. I think it was an E973 though.

Yeah, I need to make my searching skills better. I did not know that there is A "Super One-Click Root" for ICS/JB. I believe in 2.2 and 2.3 days, there is one like this piece of rooting method but the development stopped after 2.3 for ICS has a very different system. Now some genius came up with this one....simply awesome!
EDIT: and it is a good idea to push "SuperSU" rather than the traditional Superuser app. It works better on Android devices with a custom UI on it. In other notes, I unlocked the bootloader (i think) but I don't see any indications on boot screen whatsoever that indicates that the device is unlocked. Maybe I failed on the boot loader unlock...

[Q] Korean F160s

hi, merry christmas and a happy new year, i received from a friend today an lg korean version f160s, acording to some post, over the internet the specs are
lte and network CDMA800, CDMA1900, 802.11b, 802.11g, 802.11n, Bluetooth 4.0, NFC,
but if you check on lgetool site
http://www.lgtool.net/phones/F160S.html
LG F160S
LG F160S is a GSM phone supported by LGtool.
Instant unlock by IMEI is supported by LGtool for this phone.
And since i have worked with some samsung and motorolas from sk korea, if you flash a compatible version form another model acording to the one that your trying to unlock, if succeded it works on a gsm network.
i believe that sk telecom uses gsm phones but with the imei and unlocking options removed or hidden.
this phone has an imei, so i believe it could work on a gsm system, and if posible can someone please, guide me, on how to remove sk bloatware to be able to input a network unlocking code? or how to change the rom to a compatible one for sim unlocking purposes.
examples
motorola xt910, xt720
samsung shv- e120s, m110s, e210s, e210l. shw- m110s m130k m130l, m190s, m240k, m240s, m440s.
that are from korea, and can be unlocked and used in gsm systems.
thank you very much indeed for your help

I am no expert, but I would be REALLY surprised if that is possible... According to specs, this is not a GSM device, and it makes no sense (to me, at least), that the GSM functionality would exist in hardware, but somehow be "hidden" or disabled in software. As regards to your examples, those are in fact GSM phones - both Motorolas, Samsung E120S, M110S, didn't check further...

posting this to just answer and because there is no forum for lte2 here...
f160 / lte2 is a cdma phone just like any other Korean LG phone like F180.
so just pop in the sim and it will work, but you wont get edge.
3g / lte are also dependent on the frequencies of your country and providers.
i had f160 and there is no english counterpart for tghis phone like f180 which has e975. its a decent enough phone, just root and remove the korean apps.

The first part is correct, the second part is not quite so... F160 is indeed a CDMA phone, but very different from F180, which is a GSM device (with WCDMA and LTE as well). The OP's question was about using F160 on GSM networks.

Calm down, will ya? The part I dont get is that you said youself it's a CDMA phone. F180x models are all listed as GSM devices, but F160x are spec'd as CDMA only. I don't have an F160, and I don't have a reason not to believe you - if you are saying it works on GSM networks, it means the published specs are incorrect, that's it.

i was pretty normal, perhaps my reply seemed im not.
yes F180 is speced wrong because its similar to E975 so they just put like e975, F180 ... blaa blaa. but it is exact to what gsmarena says for lte2.

Nah, it's all good... Your response did sound a little bit... overexcited, but I sometimes get that, too.
On the topic, though, it's interesting that the phone which is very specifically listed as CDMA only (GSM Arena is one example, but other places have the same apecs) actually works on GSM networks... It does sound like it's similar to the F180 family then.

unlock korean XT720
Go online and get you unlock code , update you phone to a custom rom you will find plenty of these on this site CM7 i used from J.Y daddy, then place in you sim and you will get request for a unlock code.
"Korean phones have this functionality removed so updating is the only way".
as for the use of the phone just like it is now, i just poped a 900 and 1900mhz claro sim card and, no network code request, but emergency calls only,
in the mobile network menu settings
Network mode
select a LTE/3g network
so unless it has a hidden menu to change bands, i will believe that it's imei in this case is only for LTE non gsm calling at all, or i do need a custom rom to habilitate other options.
i always believe that gsm arena listed 100% accurate specs.
but no, sometimes it says that it is not a gsm device specially, in asian devices, and at the end they turn to be gsm capable.
thanks, any other advice?

inshort
F160 will work on gsm sim if its not carrier locked for some reason. (mine was not, no code request or anything)
F160 will work with GPRS but not EDGE on gsm sim.
F160 will work on 3G if the frequencies match with the carrier in use.
custom ROM or Stock, doesn't matter. hidden menu is same as for e975, search for it.
dont want to be rude, but we have enough talk about the phone here, you can find info elsewhere.
you can always talk in General section but not in device specific forum.

[Q] Sprint LS980 Penta LTE band (5 bands)

Hi there,
I hope that I'm posting on the right place and sorry for my bad english.
I've searched everywhere on the web for infos about the sprint lg g2 ls980 lte limitations, and there are quite a lot of suggestions that the limitation is hardware level.
Today I found a guy that sells ls980 on ebay and he guaranties that the llimitation is sofware based and that the ls980 that he sells is open to 5 lte bands. He told me that you just need to instruct the modem to communicate on those frequencies.
Is this possible, a scam, something new.??...
Please do comment about this subject, all comments are wellcome.
I can't post the link for the ls980 on sale, but the sale title on ebay is :
LG G2 32GB Unlocked Worldwide & Rooted Smartphone Android 4.2.2 Jelly Bean
The seller is : droid_toy
For info, I have an ls980, allready flashed the same rom the guy uses but no 4g on band 7 with my sim card, and he states that the band 7 works on hes ls980.
Thank you,

I'm sure its possible maybee even more but good luck on the radio thats carrier based

I don't really know how the guy has done it...
Allready tryed, with an d801 from tmob, to flash it with an d802 rom, then flash an d801 kernel and no other ltes other then the original ones. The weird thing is that if then I try to flash just the radio over all this it will brick, what I find weird since the rom is allready a d802 rom and it is just the boot that is from a d801. (Flashing boot and radio changes commun things?)
Anyway, back to subject, if this method fails then on ls980 it also fails...
How it is possible to have other radios on ls980 and he acctually accepts then well?
Also the d801 when unlocked by code doesn't unlock other lte bands, so for ls980 it is not that either... I haven't tryed yeat, but I belive that with an d802 base rom on ls980 we gain access to same dial codes then d802, so it turns out to be possible to unlock the phone by code. Am I correct?
How can it possibly be done, can you point me some directions on how to try to unlock the lte bands?

Hi there,
No suggestions, no ideas, anyone?
Is it possible that the lte band permission are guiven by the kernel?

it is not a pentaband phone and it is a hardware limitation so buyer beware and don't get ripped off

Hi there,
Sorry to bother you again, but, are you 100% sure?
According to this site http://pdadb.net/ both ls980 and d802 models share the exact same processor, and this processor has the modem integrated, so, booth models should have the same capabilities.
What am I missing? Is there any other chip associated with the modem and responsable for the bands comunication?
Thanks in advance,

its not the chipset that is the problem it is the actual physical antennas you can have the same chipset in all models but the actual antennas are different making it not possible to pick up the other signals. Thats what makes it a hardware issue
Also I can not find the seller on ebay

For info, I'll continue to report my experiences.
As I think I've understood on the web, the 4g antenna is a part of the flex,/micro/charger piece.
As I have a few spare parts, I tryed to use a d802 motherboard with a flex cable I had from an ls980, to try and see if I would loose my band 7 4g on the d802.
Didn't worked at all, the d802 couldn't detect a sim card with that combination, whitch I find a bit weird as result since the sim is connected to the noard...
Next step, I'm waiting for some parts to try a combo ls980 board flashed with a rayglobe firmware + d802 flex cable (4g antenna).
I don't have much hope but, hey, we never know...

[Q] Is it possible to convert a Asia WWE model to US WWE or EU WWE?

Hi guys, my cousin just returned to Mexico from a trip to the US and she bought an HTC One M8 on BestBuy. The thing is that she bought it from a partner inside the store and the model is HTC Asia WWE. She wasn't able to connect to LTE there and neither here on Mexico now that she's back.
Here are the LTE frequencies I looked up:
LTE 700 / 850 / 1700 / 1800 / 1900 / 2100 / 2600 - AT&T
LTE 700 / 900 / 1800 / 2100 / 2600 - Asia - the phone she bought
The phone CID and MID are:
CID HTC__044
MID htc_asia_wwe
She can only connect to H and 3G (no H+ or LTE) with Telcel and was wondering if I can convert her phone to the US or EU unlocked model so she can have LTE speeds. It's weird that a partner inside BestBuy was selling unlocked asian models instead of the US ones and she has no other option now.
I can't find any info regarding the cellular hardware to see if a conversion is possible.
I have plenty of experience on my One M7 with WWE conversions. I once converted my US unlocked model the EU one in order to get Sense 5.5 first and to play around and get experience with the One's specifics flash methods, etc. but I don't know about other region's WWE models and the different frequencies they support. Are they hardware dependent or just by firmware/ROM?
She will be more than happy if I can convert her phone to a US or EU model and have LTE connectivity.
Any help with this question would be really appreciated. Thanks in advance!

It's AT&T that use odd frequencies, not Asia. The different frequencies are a hardware thing, and I think there may also be a protocol difference (AWS?). It can't be changed.

Frequency support is set in hardware and can't be "converted" with software. In particular, according to the following Wiki page, Telcel uses Band 4 (1700 MHz) for LTE, so you need to use a phone which supports this LTE band (which the Asian variant does not).
One has to be very careful (and do a lot of research) whenever buying a phone from a source outside your local carrier,region, etc. for this very reason.

Have a similar compatibility question ... Product specs for the phone I bought in India say that it supports the following 4G LTE frequencies. 700/900/1800/2100/2600. I am trying to use that in the U.S on AT&T which (according to the Wiki page) uses 700, 1700 and 1900. So, techincally shouldnt the phone work on the 700 MHz frequency. I dont think it is that straight forward since the is a "band" variable that I am assuming plays. Appreciate any clarification...

Yes did it, from asian cht to europe.. change model id and cpu id and you are free to convert

Wonderful to know. But, can you let me know the steps you took to update mid and cid and what you would update it to and what you did to "convert".
Thanks!!

Nan i dnt think so, all device hardware is the same, modem frequency do not rely on the hardware, i think its depends on the software configuration ( which band to enable or not).remember radio is integrated in the snapdragon 801 only changes is the increase in speed of the Asian version that all everthing remain the same.. i converted my Asian-cht to european-wwe, i am in mauritius and i get 4g on the two main carrier in my country.

Awesome. Thanks!!! Let me try this and get back. Will definitely would want to have an option to go back to stock if something goes wrong.

I really don't know what you're trying to show me.
The Asia and the EMEA HTC One M8 both support LTE on 1800MHz, the frequency that Orange - Mauritius operates on. What am I missing?

Thats a good question.. i will search for the frequency and post it later.

check the conversion guide in my sig. after a good read of the steps and links you can use this to convert to any GSM variant. (common sense required lol)
I converted back from Dev edition to european last night

Yes, I was just reading last week on a post here that apparently radio support is no longer set in hardware, but that the Snapdragon chipset can now support all bands, and its not set in software. This is a significant change in technology for previous smartphones.

So, how can I test this? If I get a radio from AT&T and flash it onto the Indian M8, would that turn on 4G LTE for the Indian phone in the US on AT&T?

All M8s using the same radio and multi-band amplifier. So the bands are activated through firmware.
It's been done before. When Nexus 4 was released, the multi-band amplifier supports one LTE band and people were able to get LTE signals and speed. Google later issued a radio firmware update that disabled the LTE. Subsequently, devs hacked the radio firmware and created "hybrid" radio that contains the newest update and LTE.

All new snapdragons support "World Mode" modem. All M8s use "World Mode" amplifier. Technically M8s can support ALL possible LTE bands.

I'll believe it when I see it.

I plan on trying it out but being a noob will need some help. I have a locked, S-On Indian M8 (CID: HTC__038). To test a new radio, i would:
1. unlock bootloader
2. root
3. S-OFF
4. How do I backup my current radio to be able to go back to it if the new radio does not work?
5. Change CID and MID to match the AT&T
6. Flash new radio - Where can I get the AT&T radio.
Anything I am missing or incorrect? Appreciate any input.
still havent sold my s4 so I guess I would be OK even if it is bricked but would prefer not to

What exactly are you asking
You don't know how to use the phone? You don't know what to do with your phone? Did you try the user manual that accompanies it?
Are you referring to what you can do with the phone in terms of custom ROMs? Are you asking about the hardware in the phone in regards to the topic at hand(RF360 Front end Solution from Qualcomm) ?

Flashing LG H815(International Version) rom onto LG H812 (Bell Canada) hardware

Hi all,
I am going on a long trip to the UK and Middle East, and want to take my LG G4 with me and use foreign service providers. I am planning on flashing the H815T (Similar to H815 International Version but supports more bands) KDZ file onto my existing LG H812 (Bell Canada) hardware, so I can have support for those frequency bands in the UK and Middle East.
According to my understanding, the H815T rom is compatible with the H812 hardware, as both the Bell Canada and International Versions have the same underlying hardware, but I would gladly appreciate if someone can confirm this. I have attached the phone details below.
Thanks and all the best!

The risk is not worth it ...

The risk is not worth it ... It is a lot cheaper to carrier unlock your phone so that you can put any foreign service provider's SIM card in rather than having to buy a new phone when you (hard?) brick it, i.e. ~ $20.00 vs $700.00 (or ~$150.00 on ebay for a used one).
But if you insist ... carry on.

I have done so previously with Samsung Galaxy S4 (all had different model numbers), I used to flash different carriers firmware regularly, as I travel quite often. Just wondering whether the same is true for LG.
Thanks!

Unfortunately ...

Unfortunately ... because you cannot unlock the H812's bootloader (at this point in time, any way), you cannot safely flash different firmware in the same way you did with your Samsung. Unlocking your carrier so you can replace your SIM card with foreign providers and if you wish, installing steadfasterX's TWRP-in-FisH to have a custom recovery is about it for now. If and when steadfasterX completes his efidroid port to LG G4 locked devices (he's working on it now for unlocked devices), then you may be able to install different firmwares.
All of us H812 owners as well as many others are in the same boat.
Safe travels,
S.

I read so much of bands because of Xiaomi phones. I don't think it would work. You need hardware for bands

Can you confirm that frequency bands are hardware based?

For Xiaomi yes: they unlocked the bands, still couldn't get running. I can't tell for LG, maybe every LG uses same antenna or they using different antennas. Check out, if your phone requires special antenna, then you now for sure. Just check that out, before you spend your time on this.

So if they are hardware based, then howcome when you unlock the phone, it suddenly supports all the bands? Also by antenna, do you mean the GSM transmitter and receiver?
