Canada Telus,Rogers or Bell Galaxy Tab 10.1 4G stock rom

I missed up my Telus 4G 10.1
I could restored back but it seems I used unbranded 3G stock rom
it works fine but network mode showing CDMA not HASP+ as expected from 4G
so it behave as 3G not 4G
if anyone can post canadian stock rom or even a backup that would help me to bring back to normal

don't have the original firmware for my Rogers Tab. They are labelled 4G in Canada but that is actually 3g+ (there is a nice wikipedia discussion you can look up) and the Rogers model at least, will only run on 3G firmware not the LTE versions you can access -- the bootloader on mine has KG8 as its firmware, you can download that from sammobile if you want to restore your system or you can download the latest 3.1 firmware Ki2 here on xda or through check fus. The most recent firmware is 3,2 and there is a stock KJ6 version and a custom version Overcome 2.0.0 available.
The 3.2 based roms are significantly smoother,faster and without the launcher and browser lag sometimes evident with 3.1.
So, if its just to maximize your own use, I would suggest either stock or custom 3.2 firmware -- again, they will all show 3G as designation.

I already installed the KJ6 3.2 which runs very smooth with no problem
but I can see only CDMA or GSM
what you see in your network mode is it CDMA or HSAP as mentioned in user manual
and if I have a data plan up to 21 mb/sec do I can get this speed with this KJ6 rom

download network signal app from the market: it displays the signal our device is actually receiving on either wifi or 3G+: the device will support the speed, it whether or not you are in an area with that coverage
rogers will show umts
as wikipedia explains
UMTS supports maximum theoretical data transfer rates of 45 Mbit/s when HSPA+ is implemented in the network.[2] Users in deployed networks can expect a transfer rate of up to 384 kbit/s for R99 handsets, and 7.2 Mbit/s for HSDPA handsets in the downlink connection. These speeds are significantly faster than the 9.6 kbit/s of a single GSM error-corrected circuit switched data channel, multiple 9.6 kbit/s channels in HSCSD and 14.4 kbit/s for CDMAOne channels.
Since 2006, UMTS networks in many countries have been or are in the process of being upgraded with High Speed Downlink Packet Access (HSDPA), sometimes known as 3.5G. Currently, HSDPA enables downlink transfer speeds of up to 21 Mbit/s. Work is also progressing on improving the uplink transfer speed with the High-Speed Uplink Packet Access (HSUPA). Longer term, the 3GPP Long Term Evolution project plans to move UMTS to 4G speeds of 100 Mbit/s down and 50 Mbit/s up, using a next generation air interface technology based upon Orthogonal frequency-division multiplexing.
the last iteration is LTE which we can access using the 7500 version we have but not with the sim card we have

Howdy! I have a stock Canadian (Telus) Samsung 10.1 4G [GT-7500DTLSKH4]. If you'd care to provide explict instructions (for this Telus model) on how to root and backup rom, I can archive and forward. If you also have instructions to "unroot" said device, that would be greatly appreciated, too. Further, have you received the 3.2 update for this model as of yet? If you have, was it VIA WIFI or OTA? The reason I ask is that it informs me there are no updates available (I use WIFI only at this time).
Thanks in advance!
Thomas

For Telus:
www.sammobile.com/firmware/?page=3&t=3&o=1&m=GT-P7500D&r=-1#modelsa
Rogers, and Bell also at SamMobile Firmware page.
Telus is 3.1 (as is bell)
Rogers updated to 3.2 but has lots of rogers crap. ALSO note your telus sim with this firmware will pull the wrong apn, it'll get sp.telus.com and leave you with a HUGE data bill. SO if you use it make sure to change the APN before connecting to mobile data to isp.telus.com
Enjoy

Can the Rogers Firmware be installed to the bell model?

In the development forum the stock rogers is there ... I have the 7500r and running latest ics working great .... data rates are perfect

Yes you can flash bell, rogers or telus firmwares. I've converted several.

I hope you will forgive me for clarifying but I have the 7500R and I could flash the 7500M bell firmware to it with no issues?
Before any one asks why I would like to ask my other question... Has any one seen a Galaxy Tab re network lock? My device was unlocked since like November and all of a sudden today I am getting the SIM network unlock PIN. I tried the original unlock code but it doesn't work. As well I took the bell sim and used it in the Nexus S and accessed data so the sim seems fine. I know this might need to go to another thread but I thought maybe I should try flashing the bell rom? As well maybe I should just try a hard reset first? Any suggestions.
Thank you...
So it turns out some how it must have relocked... I used an app from the Marketplace that I linked to from XDA and unlocked it again... The original unlock was a code entry so I'm not sure why or if it should have relocked but I am back up and running now.

Sorry for the super late reply, I don't really monitor the threads.
Anyhow yes you can put any of the Canadian firmwares on your Rogers Tab. Or vs. No issues I've seen to date.
As for your second issue. A few months ago the same thing happened to one of my tablets it seemed to relock itself and would no longer accept the factory unlock code. I had to edit the nv file directly to fix that issue. And strangely enough another phone I had from Telus Samsung facinate 4G, did the exact same thing, and then another when that one was replaced by Samsung. On the facinate using a telus sim the phone would still ask for a unlock code. So something strange was happening. The phones were brand new, and never rooted, completely stock. The only thing I did was put in my kodoo sim and enter the unlock code.
So three devices in total did it.

No problems on the late reply. I ended up using an app by one of the xda members to edit the nv as you mentioned you had to do. I am actually very glad I purchased the app as it appears if you dont reverse it to check for firmware upgrades it is failing to connect.
In regards to the roms does anyone have any experience with one being better then the other? I am using a bell sim so was just curious if I should flash bell firmware.
Thank you for your reply.
Sent from my GT-P7500R using XDA

The firmware has nothing to do with your sim... I am running a generic ics build on my rogers p7500r, rogers 3g+ stillbworks, I plug in my tmobile $2/day sim card and it just works.
Good luck, pershots daily ics builds work great and so does overcome!

[Q] Galaxy S5 Active on T-Mobile

T-Mobile uses the 1700MHz and 2100MHz frequencies for 4G LTE data, and the Galaxy S5 Active supports 1700 and 2100, according to GSMArena.
1) Why then is the phone listed everywhere as "For AT&T"?
2) If I buy an S5 Active without a contract, how will data work on T-Mobile? 3G? 4G? 4G LTE?

Any given S5 model has the hardware capability to operate on all of the GSM and LTE bands. But Samsung can sell more phones, and carriers can deter you from jumping ship too readily by marketing lots of different S5 models that have various incompatibilities.
The S5 Active or SM-G870ADGEATT is a ruggedized variant, exclusive to ATT. So why is it said to be for ATT? Marketing.
As to compatibility with TMobile, assuming that you SIM unlock it, it can operate on most of the TMB bands. But again ATT has put a lot of thought into how to discourage you from moving to a different carrier. To wit, they have omitted support for TMB's 3G 1700 and LTE band 8.
You'd have to find out how widely TMB uses those bands to know if that would be a large impact on data use or not.

There was a rumor posted 2 months ago on the Android Community that a T-Mobile version of the Galaxy S5 Active (model SM-G870T vs the AT&T model SM-G870A) would be out in late July. Here's a link.
http://androidcommunity.com/samsung-galaxy-s5-active-availability-leaks-out-20140529/
Obviously it's late July now and we haven't seen it but I'm wondering if AT&T got an exclusive on the Galaxy S5 Active for a few months and T-Mobile will release it after the exclusivity period expires.

Sorry to dredge up an old topic, however you mentioned that the S5 active has the hardware capability to support all TMB bands, 1700 included, but then say "To wit, they have omitted support for TMB'S 3G 1700 and LTE band 8". Does this just mean the stock AT&T ROM is the only limiting factor? So, were I to flash the AT&T stock ROM and install a Tmobile ROM for example I could then utilize ALL of Tmobile ' 3G and LTE bands? (And wifi calling to boot).
Thanks

S5 Active is pretty limited on Tmobile network

I NEED to do something with my S5 Active to get it working better on Tmobile. I love the S5A... its a perfect phone for me. Not too big, but big enough. Rugged, waterproof, good camera, uSD card, etc. Without WiFi Calling and support for all of Tmo's freq & channels, its severely limiting.
I'd pay someone to help me convert my phone to Tmobiles stock S5 5.1.1 ROM and baseband radio firmware.
Help!
Jim

Also having the same problem with an unlocked S5 Active originally setup for AT&T. It uses the EDGE network only.
Has anyone successfully modified the phone to utilize the TMB 1700 band or the LTE band 8 as mentioned in this post? (either through ROM upgrade or other)?

I love the S5 Active, but using it with T-Mobile is such a hassle. I have the $30/mo. prepaid plan that includes unlimited text and data, so I'm not changing carriers anytime soon, but I have to buy new phones outright. When I bought this for myself last December, I saw it was compatible with T-Mobile so I pulled the trigger - a mistake in retrospect.
I'm from a large metro-area but T-Mobile's 4G signal is nearly impossible to get with this phone. Aside from never being able to connect to the internet when out of my apartment, sending/receiving MMS texts are a chore. I also discovered today that my android OS with this phone hasn't updated itself since I bought it - it's still running 4.4.2 and when I try to check for updates to Android through my device settings, it tells me AT&T has no new available updates at this time (there have in fact been 3 new updates AT&T released during this time).
So while I really love the phone, I'm going to have to sell it and look for a new device that's actually compatible with T-Mobile's network.

The Fix
I would go in the VPN settings and manually reset the ports and frequencies the phone reads and when it reads the T-Mobile sim card that it reads upon boot up.
Now, I'm running similar set up with Samsung Galaxy S4 & S5 (At&T variants), it seems like it works, have tried it on friend's S5 Active and it works perfectly.
The only problem is that you won't get to enjoy the freedom of wifi calling even though u have T-Mobile sim card and service, But at least u will be guaranteed to use T-Mobile 4G LTE speed and signals. Occassionally, T-Mobile will blackout or a region without T-Mobile and automatically the phone will roam with no charge and use AT&T signals for up to 15 minutes or depending to circumstances of the situation.

To get the At&T updates, I would advise you to go to Ebay and buy a prepaid At&t sim card for the phone and use it temporarily just to update it all the up to 5.1 Android OS and your phone will be running up to date. (cost anywhere from $3.99 to $15.99)

I got the AT&T updates by going into a Best Buy where they have a Samsung Experience center, took about 10 minutes but they updated my phone. I'll have to look into the VPN settings and see if there's anything I can do, but after purchasing the phone online I did have the folks at a T-Mobile store set the phone up for me so I would've figured they would have set it up proper.

I have a S5 Active and I was considering making the jump to TMo, but I really would like the functionality of the wi-fi calling and text, since I work in a hospital and can get no reception or texts. Pardon me if this is a dumb question as I have no experience in jumping carriers with rooted phones, but would I get the features if I had the TMo sim, applied the TMo APN's, flashed a TMo stock or custom rom that has the features baked in? Would I just flash the 870a kernel to make it work? Anybody that has any ideas, I would love to hear them. Thanks

I'm on T-Mobile, would it be worth getting the S5 Active? I currently have the S4 Active.

ZE552KL not connecting to LTE band 17.

Various websites confirm its compatible with LTE band 17. My other phone connects to it while in my house, but the Zenfone will mostly connect to HSPA+, or sometimes LTE band 2. I cannot get it to stay connected to LTE unless I get into town or on the highway. (Actually as I'm typing, it switched to LTE band 2, but in awhile it will go back to HSPA)
If I root is there any way to unlock band 17? I'm in the US and my carrier runs off AT&T towers. I got this phone specifically because band 17 reaches far off places much better but I am unable to use it.
Edit: I just realized the model number in the Android settings is "asus_Z012DA" and that apparently is not a US variant. I didn't know about the different variants at all. Am I out of luck?

Hi!
Your correct model for band 17 should be Z012DC, the same used in Brazil.

For the time being yes you are. There is a way to unlock LTE bands on Qualcomm devices, but it seems ASUS has a fail safe built into kernel preventing it at the moment. If there is ever a custom rom developed for your phone then it maybe possible to unlock band 17. Until then no. I have been trying on my Zenfone 3 Ultra. Got as far as entering in the values for the bands I want and when I reboot it resets them to default. You can read up on it here:
https://forum.xda-developers.com/zenfone-3/help/help-putting-phone-usb-diag-mode-t3571627
Me and another user have been working on it. Maybe it might work for your phone. Always a chance.

Yeah I realize that now. Even though I'm stuck with my phone, I still can't find the z012dc for sale anywhere. Practically no seller online lists which variant it is. In fact, after a few hours of research, I never even knew there was specifically variants.

Whoa thanks man. I'll keep checking back and maybe I'll try it myself. Seems you guys are close.
I must say though, this isn't a complete deal breaker, though I am stuck with this phone anyway. The Hspa network is actually FASTER than LTE band 17 in my house. I'm just afraid if I travel somewhere and only band 17 is available I might run into some trouble. But then again, 3g or Hspa might still be able to connect.

GT-i9515 only 2g speed?

Hey everyone,
I read for hours but unfortunately I haven't been able to find the solution.
So I bought a Galaxy S4 GT-I9515 in Europe and I'm not able to get any speeds higher than 2g on my USA 4g T-mobile plan.
The network mode is set on auto connect (LTE/WCDMA/GSM). I tried setting up a t-mobile 4g APN but it won't accept it (it pops back to standard after a few seconds..)
The simcard does work at 4g on another phone.
I rooted it with chainfire autoroot but this made no difference.
Anyone have a clue? At least 3g would be nice and should be possible..

Does the gt-9515 support the carrier's 3g and 4g frequencies?

Hey, thanks for thinking along..
According to frequencycheck.com, yes (both 3g and 4g).
Also, the t-mobile store didn't make notice of this being a problem. They were horribly incompetent though (just googling everything..) But you'd think they would at least check that much.

The I9515 won't get LTE in Europe as bands 2, 4, 12, and 17 aren't used there. The best you can do is HSPA (3.5G in the US) for data. If you're not getting at least HSPA the local carrier may have throttled you.

If I put the simcard in my old phone (moto G 1st gen) it makes an LTE connection so I'm not throttled.
I downloaded an app called LTE Discovery which doesn't read an LTE connection but says HSPA: -75.0 dBm is available.
With an internet speed test I'm only getting 770 Kbps however.

Oh, and I'm in Las Vegas currently (not in the middle of nowhere before anyone asks.. )
It's about the same speed in the Bay-area.

I misread your initial post. The fact you're not picking up LTE in Las Vegas means something else is wrong. In fact it makes me wonder if you even have an I9515. Kindly enter download mode and read off the model number please?
If things are as I suspect they are, then you're actually in possession of an I9505. My comments in my earlier post regarding LTE still apply, except it's the phone lacking the US bands instead of lacking European bands.

You're right, I mentioned the US T-mobile plan but forgot to clearly mention where the problem was occurring/where I want to use the phone (which I bought in the Netherlands). Just to be clear: I am in the USA and that's where I intend to use it.
ODIN MODE
Product Name: GT-I9515

Ok...I'm really confusing myself. For some odd reason I had the Straight Talk S4 in mind. LOL.
The I9505 and I9515 have the same bands: 1, 3, 5, 7, 8, and 20. You won't get LTE in the US on this device and are limited to HSPA here. Fortunately, HSPA is fast enough for multimedia​, so unless T-Mobile is repurposing its 3G network for LTE you should see about 4 or 5Mb a second.

Thanks for analyzing, you seem to know a lot about this.
However, the primary problem is I'm not reaching any HSPA speeds either.

I know a lot about this, as I have an I9505 and live in the US.
The phone is working properly, so speed issues are carrier related. And it's not uncommon. I've had it happen myself, on AT&T towers.

V20 LTE Band and Compatibility (vs995, h910)

Hello everyone! I'll start by saying I've done a lot of reading and searching, and I can't find my answers, so that's why I'm posting.
I recently acquired two LG v20s, which I intend to use as my primary daily handsets. The models are the h910 (att) and VS995 (verizon). Both have TWRP and magisk etc. I love the phones so far and everything is peachy, except one ... sordof big question/issue. LTE bands!! I've seen several people on XDA talk about the bands but I can't determine a clear answer. My first and primary question is, DOES the h910 support band 12/17?!?! Using network signal guru app, band 12 is listed. From what I understand (from what I have read) band 12 IS supported, and 17 is actually a thing of the past. If your phone has band 12, it can pick up all band 17 towers no problem, essentially meaning 12 has replaced 17. However, my h910 WILL NOT use band 12. Not if I force it, not on its own, nada. This is in places where I know band 12(17) exists, and is the strongest signal. In fact virtually everywhere, around the area I live (chattanooga TN). What actually really surprises me is that the phone gets great LTE reception everywhere I am 95% of the time, without band 12/17. I've checked numerous times (its kindof an ongoing thing...) and I've gotten every single other band, (2,4,5,30) usually with great reception and acceptable or good network speed. But never band 12. I can hold my galaxy note 4 right next to it, and the note will almost always be using band 17, and the LG refuses. Again , I can lock bands with Network signal guru, and still no bueno. If I lock the lg on only band 12, it will simply revert to HSPA.
Does anyone else have experience with this? Are other h910 users able to get band 12? Could I have a faulty handset? Is it software or hardware related? Just curious if anyone else has any info that could be helpful. I have noticed people in other random forums saying their v20 gets poor signal compared to other ATT devices, and I'm wondering if this is why (no band 12). Most people wouldn't know how to check what bands they're getting... or even know what "bands" are at all.
And a quick question about the vs995... I put an att sim in it, and got absolutely no signal at all on any band. Whats up with that?
Thanks in advance folks.

Seems US telecom companies are just weird I have 3 V20 phones that I use as 4G modem when in the country. My Vs995 worked for this for years but suddenly will not use mobile data here in Norway, tried factory reset. 1 910 that does not get phone signal at all - gave up on it, transferred screen and case to the VS995 which was worn, had broken screen. My Korean F800 with android 9 works fine. US carriers place artificial locks on bands it seems.
