Hisense A2 Connection Problem to 3G and 4G - General Questions and Answers

Hi All,
Meanwhile i do have my Hisense A2 for nearly 2 Month. I am a TeleXXX Customer and was having no problems with connectivity for my older Smartphones.
With my Hisense A2 it isnt possible to get a Dataconnection higher than 2G and all without working SMS. WLan is working very well.
So i was searching for Help in the Worl wide web.
I tried the correct APN from my Customer.
I was resetting my Phone.
I upgraded by the English/Chinese Version, and downgraded back to L126.1.6.03.09.00, thanks to Baistan.
Meanwhile i am near lost by find my Failure.
I rooted my MDA Innovation, my S2, my S5, my Ipad...., but my Original Hisense A2 wouldn`t work.......
Is there anything i can do, to get it work correctly? Is there another Thread i havent found?
Are there different Versions of that Phone, or do i have to upgrade the Baseband? (937_GENNS_PACK-1.79261.1.82796.1 (Kernel 3.18.24))
Thanks for Your Patience and, maybe, Help.

LTE and UMTS use different frequency bands and modulation types in different countries.
The A2 was made for the chinese market, and may not work well or at all on 3G/4G in other countries.
I'm kind of in the same boat, I'm using the A2 in Switzerland and can only use 3G but not 4G.
You didn't say which country you're in. Your phone may work with a different operator but I wouldn't bet on it.

I have found A2 works on ATT at 4g and 3g but only 2G for T-Mobile in US.

It's complicated!

Hi fellow Xoom owners.
I'm having this issue with my 3G Xoom that I can't just get past.
As soon as FedEx handed me my internet-ordered tablet, I started looking into rooting methods and all.
Strangely, even though I live in Saudi Arabia, I received it with the US firmware, kernel or whatever it's actually called (MZ600 - XOOM WITH WI-FI + VERIZON 3G Build HRI66) which I didn't know at the time it was Verizon's but was wondering why 3G didn't work.
Anyway, I followed a rooting tutorial without paying attention to the build which got my Xoom stuck into the Moto logo thing.
Following tutorials into how to restore it, I downloaded the right build for Saudi Arabia (MZ601 - XOOM WITH WI-FI + UMTS Build H.6.1-38-9 for Retail Other International) which worked like a charm and with 3G!
Since, at that point I was already out of warranty, I flashed a Tiamat ROM and worked great but without 3G (bummer!).
Going through ROM trials, I'm now on Team EOS Verizon 4G ICS ROM but, as you've already guessed, no 3G for me (duh!).
I noticed that Team EOS are also working on a MZ601 ROM which should have worked to my favor of regaining 3G back but is somwhy isn't.
Bottom line of the story, I want to regain my 3G back while staying on an ICS ROM, preferably Team EOS's .
It's way better than the Honeycomb it came with and I'm not ready to lose all my game save files again!
Please help me.
The Link you provided in you post (Team EOS Verizon 4G ICS ROM)- That Build is not for your Device, as you device is not MZ602 with 4G LTE. Seeing that you received a US MZ600 Xoom that is actually CDMA and not GSM, it is suprising that the MZ601 UMTS worked for you. But since you say that it worked:
Try this one Team EOS ICS, EU 3G Xoom (umts_everest / MZ601)

Google Applications (Required for all devices)
http://http://goo-inside.me/roms/teameos/gapps/EOS_GApps_ics_4.0.3_v10.5.zip
As Always, If This Was Helpful - Hit The Thanks Button!
I've already tried that ROM and for some reason it did't work.
Though on earlier versions, it used to give me a certain error which goes something like "phone.android.'something' stopped working" but now it doesn't.
As for the build I received it with, I haven'y the slightest idea how that happened!
I even took a picture of of my tablet before rooting in case anything went wrong... here.
Check this thread, you can try out Umts Everest - Euro & also Stingray 3G, as you are having CDMA xoom

Seems promising but gives me the "502 Bad Gateway" BS.
I'll try a bit later or will look for other sources.
EDIT: BTW, since I'm already on ICS, I don't need to factory reset, right?
yea there seems to be an issue with the download links.
its better to do a clean install, you can always backup your apps & data.
Since you brought it, how can I make a backup of my data?
By data I mean game saves 'cuz that's what I can't afford to lose {: s
I wanted to install CM9 on my Galaxy SII but stopped at the same data backup problem.
And, isn't there any tool to use on my PC to backup apps & data and manage my device ROMs... etc?
Titanium backup is one of the best apps to backup data and apps in my experience. You can find it on the play store. Also im not sure if you can buy the pro key for it but it makes reinstalling everything a breeze. Can you still connect to wifi?
Sent from my SPH-D710
@fredrick
RedXXII already gave the answer which i was gonna say. titanium backup is the best, you can backup & restore app + data easily. you just need a rooted device to use titanium backup.
So guys, let me get this straight:
You're saying that an MZ600 Xoom will work on a 900/1800 3g network just by flashing it with a european rom? I thought this was impossible
thread starter himself said that he flashed a 3G rom, which worked for him
I downloaded the right build for Saudi Arabia (MZ601 - XOOM WITH WI-FI + UMTS Build H.6.1-38-9 for Retail Other International) which worked like a charm and with 3G!

that's y its suggested to him to flash euro 3G rom
I have absolutely no idea how this happened.
I bought it from an Arabic online store for use in my country but received with a different ROM.
After restoring my tablet from the Moto logo error, I restored it to the official international firmware and it started working AND with Arabic support!
Maybe seller ordered the wrong software on the right hardware???

Agreed. The electronics involved in GSM and CDMA is definitely different. I think that is why his data never worked in the first place
OK.
I finally found working links for the codename android ROM v1.6.0 and tried the stingray 3G and the umts and none worked.
Any idea on what could be done at this point?
I re-checked the data bearers of both International and European firmwares and they are exactly the same.
Couldn't there be something like a missing driver or so that would make my Xoom recognize the carrier?
Or alternatively, isn't there a way to unlock it to any carrier supporting the same data bearers?
This is puzzling me for some time now. I have an MZ600 (Verizon 3G without the 4g upgrade) but I live in Europe. I know that MZ600 has Qualcomm MDM6600 which supports both cdma and umts. So I thought that using it in Europe would be as easy as switching Team Eos rom from "stingray_cdma / MZ600" to "umts_everest/MZ601" . I had the idea that this would change the baseband and I will manage to register on a 3g (european) network. Sadly, this isn't true and I'm still puzzled whether this is even possible or I haven't found the right way yet.
So to sum things up:
Is Qualcomm MDM6600 capable for both cdma & umts?
Is so, does anyone know someone that managed to get the MZ600 to register on a umts 3g network ?(you may see the signal of 3g but you cannot register)
If anyone can shed some light regarding this issue, it would be nice .
Check product specs for your original country and current place of use.
I believe they have totally different data bearers.
But, who am I to say?
I'm the one with a paradox over here!
so mr. Fredrick Sylar
what version of the xoom do you use...? the MZ600? or the MZ601?
well anyone ......?
have a look at this guys....

[Q] HTC ONE SV (k2_u) without LTE?

Hi guys
I recently bought a generic unbranded HTC ONE SV from a German website, as I was looking for an LTE-enabled phone that didn't have a screen big as a flatscreen TV.
I have had the phone now for a couple of weeks and I am overall happy with it. The only problem is that it does not seem to get any LTE action. My operator (Tele2 Sweden) assures me my sim card is enabled for 4G and I live in the center of a city with excellent 4G coverage. Yet, my phone shows an H at best (haven't actually ever seen even an H+).
Digging around this and other forums, I found a few indications that my ONE SV version K2_U (model id PL8013000) might actually not have support for LTE after all.
It seems also all ROM updates currently available are for the K2_UL model, including the one for JB (I have tried to flash these to my device after unlocking/rooting/s-offing it, but never actually managed to succeed with it, while I can flash and reflash the stock ROM for the k2_u version)
TBH I am quite confused: all HTC websites and reviews refer to the ONE SV as an LTE enabled phone, and I cannot find any official reference to the fact that there might be a version of this phone without LTE... So I wonder if maybe I am doing something wrong, or if maybe there is a software lock that has disabled LTE on my phone and that I can fix.
Or have I simply been screwed?
With the Easter holidays I'll have to wait until Tuesday to be able to call HTC... so if in the meantime anybody has any idea I would really appreciate it
There seems to be a lot of K2_U, non-LTE, in the US. You can have a look on the One SV root thread you'll find some.
In fact, in germany the LTE version is ONLY sold by operators (O2, Vodafone, Telekom).
All others come without LTE.

You'd think HTC would mention that on their website though... I am not upset about them selling a non-LTE version of the phone, I am outraged by the fact that they don't bother informing consumers that a phone advertised as LTE also happens to have a non-LTE version... I have also contacted them trough the htc.com website, but they did not bother to answer either.
If I had more time to waste on this I'd probably complain with the German consumer protection authorities, but TBH I have learned my lesson and this is the last HTC I buy
Thanks for your replies guys!
What does LTE means? I currently have old.splatterhands non-LTE stock rom installed for my HTC One SV. But for unknown reason, WiFi and radio connection are very weak.
LTE is fast, mobile internet.

You have the stock back/battery cover on the phone?
When you have a phone with LTE, it should be written on the backcover (4G LTE, or something like that).
If there is only written beatsaudio, you have non-LTE.
Thanks - non-LTE however

The mi4 LTE doesn't support the lower bands that is used in Sweden, therefore you only get limited access to the 4g.

[Completed] Noob in need of radio/modem flashing information

Hello,
I recently purchased a note 5 duos SM-N9208 from Taiwan. I was led to believe that the device was unlocked GSM, but had EV-DO capabilities. My understanding was that this would work on Verizon's network, because it had both radio chips inside. I was told by Verizon that "there is no approved way" for them to get me up and running on their network. The tech made a point of saying there is a difference between approved, and no way. This leads me to believe that something can be done. I'm wondering if someone would be kind enough to help me out. Phone is running original Rom, unrooted, and is basically useless to me right now, as I'm desperately clinging on to my unlimited data with Verizon. Is it possible to root the device, and flash the modem with Verizon note 5 baseband info? Any help anyone can offer would be very much appreciated.

Hi, and welcome to XDA!
When I looked up the specs on the Note 5 Duos, unfortunately it says nothing about CDMA. Having both "radio chips inside" can be taken two ways, in this case, this phone has the capability to handle two GSM carriers (and in this case, like most dual-sim phones, only the first SIM can do 3G/4G/LTE speeds).
Network Technology GSM / HSPA / LTE
2G bands GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 850 / 1900 / 2100
4G bands LTE
Speed HSPA 42.2/5.76 Mbps, LTE
GPRS Yes
EDGE Yes

It seems the only option (if you want to use this phone), is to join a GSM carrier like AT&T, T-Mobile, or one of their MVNO's (like MetroPCS).
Hope this helps.

Thank you, Joel! I'm excited to learn as much as possible from tgis forum. I actually changed over to T-Mobile, and have been good for the most part. The problem i'm having now is related to finding a way to flash the radio to all of their Rf's. I rooted, and attempted to flash the modem and bootloader from N920T, but it failed. I am still having a hard timr understanding why the identical hardware will not accept firmware from different model numbers. Again, very inexperienced, so it may be something very obvious i dont know about. If could offer any assistance, or provide and thread links that may be useful, i wpuld very grateful. Ive been searching nonstop, reading, and still cant seem to find a way.

Well, the hardware (particularly the modem) is not compatible, hance the failed install. You are lucky it cancelled out as you could have had worse problems on your hands.
The way i see it, you will have to wait for other regions for the Note 5 Duos to open up before you get flashing options. I would even question the need for that, if you get a decent range of bands with T-Mo (I am assuming you can get 4G).
If you want to explore further anyway, please check out this thread:

It did, thank you! I get decent service (including LTE) almost everywhere. Problem is, once I get to my.house, I go completely out of service. No call.I no text. It wouldn't be a big deal, but the Taiwanese phone doesn't have a way to turn WiFi calling.

Aha. That and no sign of the 700mHz band (which may not be part of your phone anyway, not just hidden by the current firmware).
Since the firmware would need deep support of Wifi Calling (or VoLTE), as in more than just an App, I am afraid you will have to wait until the Duos releases into an area with that support in their firmware (and hope that, that area's firmware doesn't disable a frequency you use).
Makes scraping all the lead paint[*] off the house the more manageable task, doesn't it?
[*] I really don't know if your house does indeed have lead paint. I am assuming it's coated in something metal, or concrete, which avoids typically high frequency radio waves from entering. I never had that problem with my house (which may be strange, since it was built in the 40's), but maybe creating ways to boost the existing signal may be in order instead.

[Completed] Please help me with my network problems on you yureka plus

Hello guys,
I have a you yureka plus phone which I bought a week ago. I'm facing network problems with it since the time II switched it on. I am not able to get network coverage and therefore very less Internet speed in my home whereas my older phone gets amazing coverage and very high internet speed.
I have contacted the sim card operator and they weren't able to help.
I tried almost all possible ways to get rid of the problem.
I tried the *#*#4636#*#* thing.
I tried changing different apns.
Rooted my phone and tried different custom ROMs and kernals.
So far global ROM miui v8 is the best one as it gives network bars but the internet speed is stilp very low compared to the other phone.
I flashed a different modem file found here in xda but that also didn't work.
I'm out of ideas and I'd really appreciate any help.
Sim cards- jio and tata DoCoMo
Current ROM - global miui v8 based on android 5.1.1
Kernal - velocity v10.3
Thank you.
Hi !
This seems to be a device specific issue , maybe your network doesn`t match the device basebands , try changing them from settings/prefered network type and also get in tuch with your provider about this
Cheers !
i tried all the options in the preferred network type with no success. my provider said there's something wrong with phone's software and he couldn't help with that

Are you sure that the phone supports your carriers bands ? You may find that you are only able to get 3g or only have one or two of the bands that your carrier uses
Regards
Sawdoctor
I'm sure it supports 4g, because I get good 4g speed in my workplace. I'm having this problem only in certain areas like my home and college. How do i check the exact bandwidth capabilities of my phone?
