can i downgrade or flash a earlier modem partition? - Xiaomi Redmi 3s Questions & Answers

i am having issues with my phone now, i only get E (edge speed all the time ever i pay my bill) i have a gig of LTE data and i always get edge speed no matter where i am in the 5 burrows of NY. this was not the case before, i never gotten LTE from the beginning because tmobile uses different bands then what this phone has< that i understand and will address another time but i use to always get H+ service watch was great and idk what happen but after some updates my service degraded and i cant figure out what it is if its ether my sim card going bad (i dont know anyone with another tmobile phone) or if my phone is messing up. I called the company and they said everything is ok on their end and that i have coverage and lte capability and insisted that it was my phone. i tried back flashing a while back and to no avail. i am about to attempt to deepflash back to factory image back when the phone first came out but i was wondering if that will even downgrade the modem or make a difference?

yes, its related to bands avalible on your phone
for instance, my carrier uses B1-2100mhz and b8-900mhz for 3g. My phone doesnt work on 900mhz 3g so i disabled it
now i got full lte and 3g(H+) all the time
try disabling one of them and see for yourself

Hmm,I haven't tried disabling bands, I'll try that although I'm phone must have gotten damaged because even a stock deep flash didn't fix it

its hardware related

I have no choice but to believe that but I wonder how I never mistreat this phone and I never even dropped it before it still in a very tough case

its xiaomi's fault

X1i when using 3G on AT&T I cant make or receive calls???

So when I leave all the band settings to auto on the phone, it immediately connects to AT&T's 3G network and shows the "H" in the title bar it worked for a little while then calls stopped coming through, after a hard reset it works again with calls for a few hours, then it begins to fail.
If I switch the bands to GSM and manually select the frequencies (850 + 1900, according to wm) then it connects to the EDGE network, and I can make and receive calls as I please, no problems, except for the crappy network speed.
So someone help me out here please, is the phone defective, or is it not working as it should because of the lack of the 850 band? I know that AT&T works on either or but this problem has me stumped.
Other than this rather huge problem (phone that cant make calls), I absolutely love the Xperia and would hate to return and wait for another.
did you try to use the connection wizard to let the phone config itself?
after I put my iphone sim in it shows the H/3G icon on anf off all the time, while I can receive call I was unable to go online.... after someone suggested me to call att to update the imei on my account to the x1, I found that I still have to go to connection and change the setting myself b4 it can go online. you will have to remove the user name and pw in media net setting and uncheck the proxy server.
I guess my case is a little different than yours but I guess you can give it a try... good luck =)
Thanks, I actually haven't tried that since i figured it would be the same as what happens when you turn the phone on for the first time, when it autoconfigs.
if it say it detect a new sim and ask if you want to do the auto config then I guess its the same... but again I did need to change some settings inside the network config to make it work too... so I am guessing the "auto config" has some flaw in it
No problem with my X1i when I venture in a1900mhz area close to my home. I live in a small town in Ca. only 850mhz here. But in the larger Metro area around me... No Problems with calls or hspeed data access...
Stuart
Thanks for the replies, It looks like the Configuration wizard in the settings menu did the trick. It do something else that the autoconfig doesnt. The phone seems to work now just fine, although it doesnt hang on to the signal as well as my old k790a. The office I work in is an ATT dead zone and I could make calls using the K790a with only one bar, with the Xperia it either doesnt go through or drops the call.
Again this is better as it works now, just not as well as my old phone.
Also, scl_electronics, so you are saying the X1i has both 850 and 1900mhz bands? I had a feeling mine did too, but I thought it was put to rest that that wasnt the case with the X1i....
Sorry Aaron J,
i should have been more specific!! Where I live, 3G is only on 850mhz band so I don't get access..Just The edge network. When I venture about 10 mile away toward the major Metro areas..The 1900mhz band are used. So the H is displayed, but I don't have those access problems for calls or data!!
But i am waiting to see if they can crack the rom for 850mhz-3G access!!

Oh ok thats kind of makes, sense although I thought the X1i didnt have an 850 band at all, so what frequency does it work off then?
Anyways, back to my problem....I spoke too soon, it dont work on 3G switched to EDGE. I might just try getting a new sim card, mine is a Cingular one from 2005, that has been in at least 4 different phones now including the X1i.

Well out here in Ca... 850mhz gsm/edge is used ..So I quad band gsm phone is handy!!!
Stuart
Yes it is! My little problem is a little confusing though as one thing I just realized that I didnt say before is that the phone has no problem connecting to the 3G network using HSDPA. I get full bars with the H icon pretty much everywhere in my area and my data speeds are very good. So I can surf the net, download programs, watch high quality youtube videos using the app in touchflo and even send and receive texts just fine.....just no calls when on 3G. I'm hoping its just setting somewhere and not a faulty device.
I live in Raleigh NC by the way so maybe it could be a faulty tower?
Well when venture into Stockton Ca. my phone switches to 3G-HSDPA:1900MHZ Without a connection hitch....
Have you tried a soft reset......
But when all else fails Hard Reset to the Rescue!!!
Btw... in several of my ppc-wm units when restoring to OEM setting(hard reset) there has been many time the process had a problem. So something would be screwed up!! So when You don't succeed, try another hard reset!!
Good luck,
Stuart
hey i was wonder if your problem is HSDPA/HSUPA being on, i have at&t also and it worked for the first few weeks fine with it being on then all of a sudden it stopped and couldn't connect to the internet, before i had the H/Edge showing up and also my email never updated when it was set to do it every 15minutes. Now that i disable the HSDPA/HSUPA i see 3G/Edge and email update all the time on the X1i. Just wonder if that might fix it, I'm all kinda still new to all this but i had my X1i for 2 1/2 weeks now.
Hello thanks for all the suggestions, Experiaenjoy, no I haven't tried mainly because I can connect to the data network just fine and get awesome speeds with full bars pretty much everywhere, all of my data related activities and programs work just fine (aka murder my battery life ). I just cant make calls while on 3G.
I talked to a coworker today who used to be a regional manager at AT&T hee said that he saw many cases of people who were having problems where it was due to the SIM card. He said they all had the older orange Cingular card and that an update to the new blue AT&T card solved all problems. So right now I'm trying to see if I can get mine updated (I do have an older Cingular SIM). Once I get that, I will do a hard reset (3rd one also done about 20 soft resets since I 've had it-I've installed a bunch of programs and tweaks) and skip the auto config and go straight to the connection wizard.

[Q] HTC HD2 w/ WP7 keeps rebooting by itself + 3G not working help?

I recently put Windows phone 7 on my HTC HD2 and everything is working fine except that the
3G doesnt work at all and when i put the phone in my pocket it just shuts off, or when the
backlight turns off for more then a minute the phone shuts off and i have to pull the battery out to turn it on again. sometimes it softresets by itself and sometimes hard resets and i lose everything. its getting really annoying and i know lots of people had problems with this, but i havent seen any threads about em, maybe im blind. if there is can someone post a link leading me there?
I got the activation code from microsoft customer service so im able to sync windows live with the phone but i still cannot download apps. it says "cannot get info at this time please try again later"
If you know the solution to my problems please help? Thanks
edit: dammit now the wifi doesnt work anymore..;-(
edit: phone works perfectly now, running on HSPA+ network at 4mbps. marketplace works fine, random reboots were from a bent battery pin from yanking the battery to hard from time to time.
i used chevronwp7 unlock to get marketplace working and to download network config app.
Looks like an incompatible sd card, have you tried another one ?
What brand, size, and class is it ?

I had also the problem with the endless booting once, get the battery out and restart again.
For the 3g you should take a look at the apn settings which you will find in the settings --mobile network---apn settings you should call your operator and ask them the required fields. I also had to set up the settings manualy by myself
It's your sd card for sure.
try a new one.
well i got everything running perfectly fine sd card wasnt the problem.
i believe one of the battery pins was bent
also the 3g i called t-mobile and of course they couldnt do anything so i got chevronwp7 unlock and unlocked the phone and installed some apps with it to get live services working (doesnt work with just an activation code) and ran connection setup app now the device is perfect and even on HSPA+/4G
its pretty much like an hd7 now
only problem ive noticed is battery drains pretty quickly but thats about it

HTC HD2 Don't supports HSPA+ aswell not 4g...the maximum is HSPA 7,2Mbit
For the 3G problem, try going into the settings, then click on cellular, scroll down and click add apn, then in the APN field, type in internet2.voicestream.com and leave the user name and password fields blank. If that doesn't work, try typing in wap.voicestream.com or epc.tmobile.com. Make sure you turn roaming on. Note: Only works if you have T-Mobile. As for the rebooting problem, just flash the ROM again and it should fix it.
rebooting means bad sd card

im having the same problem with my phone resetting itself. my sd card is a SanDisk 8GB. Is that compatible? If not, which ones are?
My SD card is the original and it worked fine with Windows Mobile 6.5.
its not that the card its self is faulty or bad as has been said, its that its not compatible, likely because it has low random access speeds. no two cards are alike so dont assume that if one works so will an identical card

thats what i thought as well but t-mobile had me changed to their 4g network,
and now in the top left corner of the screen next to the signal bar an "H" appears and some areas where theres no 4g coverage it switches to 3g.
also i ran a mobile speed test with the wi-fi turned OFF and it ran at 4mbps
way faster then i was doing with gprs.
trust me its fast and apparently does work with t-mobiles 4g network
i tried to post the image of the result but i have less then 8 posts so it wont let me.
you guys are right it is the SD card causing the endless reboots, but the funny thing is the first time i installed wp7 my card worked fine its when i tried a new wp7 that things got messed up

First of all, the HD2 is only a 3G phone. 4G requires specific hardware! The "H" you see shows during any high-speed data transmission. As for 3G working on the 4G network, of course it has to work...4G has to be backward compatible and support 3G. When you have "H" it means the phone is operating in HSPA speeds.
BTW...no such thing as 4G here in the states. 4G is just a marketing term being used to sell HSPA+ which is just an enhanced 3G. And which also requires hardware...so again...you can't be getting 4G service on the HD2. The HD2 hardware doesn't support HSPA+.
And for the guy who can't get 3G to work...you need to go into Marketplace and to HTC Applications and download the Data Connection app. This automatically configures your phone to the T-Mobile network settings for the HD2.
And 4G doesn't mean it runs at 4mbps...LOL! If I were you I wouldn't go around claiming things that can never exist or try to sound like you're all that on 4G.

LMAO. No such thing as 4G? There is no such thing as a 4th generation network? So GPRS to HSPA+ is not an advancement? No **** its enhanced 3G, just as 3G is enhanced 2G. Also 4G T-Mobiles 4G network apparently runs at 1mbps dl speed, where as regular 4G speeds would be 3-6 mpbs. I'm at a steady 4. You are right about the HD2 hardware not supporting 4G, but since tmo upgraded their towers i am still able to use it but not to its full capacity. Pretty much it's like 3.5G which would explain the "H" in the top left corner. And since HD2 has HSDPA it is able to have a max or 7.2mbps dl speed and 2mbit upload, which imo is more then enough.
In conclusion, rather then trying to make someone seem dumb over the internet, you can just kindly correct them. Also this website was no help as i solved the problems i was having on my own when i finally figured it out. Everyone was telling me the problem was its an incompatible SD card when it was just the battery pins, LOL.
There is such a thing as 4G, but i doubt very much that anyone is using it, more likely you are using a system based on 3G tech, such as HSPA, typical types of 4G tech are WiMax and LTE.
HSPA+ is the current maximum you can get from 3G, it is not a 4th gen tech, it is firmly 3G, or for marketing, they may call its 3.5G, which is just a bollocks marketing term.
depends
i think a lot of these problems are user-specific because i flashed the ROM again and all my problems were solved except for Marketplace, which I also fixed myself.

Sorry to burst your bubble...again...but LTE does not conform to official 4G standards. No one officially conforms to 4G standards. What the companies claim as 4G is basically enhanced 3G tech for marketing purposes!!!!

Did you actually read the information available on the net on this?
LTE and WiMax both are considered pre-4G data services, and not 3G the 4G spec was updated which ment that both techs fell short of the standardised spec after they were submitted
So, WiMax2 and LTE advanced have now been created which do meet the spec, unless it changes again. In terms of a difference between the two versions you can think of the jump from 3G to HSPA, same tech, slight modifcation
Why do you have to be such an arse? go for a run or something, the Endorphins should make you a bit more cheerful and they cost nothing.

[N9005] 4G was working. Now it's not. Help!

One morning when I woke up my N9005 was stuck in the boot animation. I waited a while but I had to hold the power button in to force a power off. Since then I have had no 4G at all. 4G was working before this. Can anyone suggest anything that might re-enable 4G?

It's nothing to do with my operator. I have tried two different SIMs from two different operators that both worked with 4G before. I own the phone, it came from eBay but as I said it was doing 4G before.

I already did that. At least I think I did it right. Afterwards it started up exactly as usual. There was no extra optimising apps like after an upgrade. I used Odin. Do you think I did it right? I also tried a factory reset. Still no 4G.

I can't help anyhow but what I do if I loose LTE connection I force it back with 4G Switcher app. You choose LTE only and it should connect (though I can't call or receive calls in LTE only mode) so what I do is when LTE conects I swap mode to LTE/Gsm auto and LTE stays as long as I'm on LTE area (until I somehow loose LTE again in area where LTE is available). Try that out maybe it will drive you to some new conclusions what the issue may be.

1- Yes, that's the one
2- It works on my Note 3
3- As to your assumption...well I'm not sure what you talk about. I'll explain my issue. Sometimes when I'm on LTE available area my phone connects to HDSPA+. Then I do what I described (I choose LTE on this app to force connect via LTE). I don't know do I loose "ability to select "LTE/WCDMA/GSM (auto connect)" as you said. To be specific what are you reffering with it to? To phone settings or to this app setiings? All I can choose on phone settings is 2g,3g and 4g. There's no X/Y auto connect. This option is in apps settings though and I don't really care what I loose there as long as it works when I want to force LTE with it. I'm courius why it's not compatible with your device. What phone do you have?
All in all in the end use of this app won't solve your issue permanently but with it you could make sure LTE receiver and LTE drivers on your phone system works. Then you could dig down further. You would just know that LTE works at all on your phone.

"LTE/WCDMA/GSM (auto connect)" is a setting on my phone. See my Screenshot_A.png above. It tells the phone to automatically switch between LTE (4G), WCDMA (3G) and GSM (2G). The other choices don't include 4G. I reach it by Settings / Connections / More networks / Mobile networks / Network mode.
Is you phone rooted? Mine isn't. Could that be why the app doesn't like my phone?
Further info: apparently the phone was originally Portuguese but has been flashed with UK BTU firmware. However as I said before it definitely did do 4G when I first got it. Samsung tried to tell me there was some kind of update that might has disabled 4G in the UK for this device. Sounds like a made up excuse to me.

I think so. Isn't the info in my screenshots of Samsung Phone Info Plus (in a post a further up the thread) enough to confirm?
If not could you guide me how I can check. Thanks.
I compared it to uk firmware on sammobile.com and it seems to match. Maybe you need to flash the entire uk firmware again in Odin?
Still same. I've taken it to a Samsung service centre now.

It's back, and it's working fine now. And, nice surprise, it was apparently just inside it's guarantee period so I didn't have to pay.
I'm not sure what they did but it's back on Portuguese firmware, which doesn't seem to matter, I just select English (UK) after factory reset and all is well.
Oddly the WiFi adapter has a new MAC address but the magnetic field sensor must be the original one since it's calibration is way off exactly as it was originally. (You have to calibrate it after every reboot by rotating the device in three axis if you want compass functions to work).

UMI Super 3G instead of 4G

Hi,
did anyone using Umi Super have any problems with using 4G at 800MHz? Im on giffgaff and even though Umi Super is supposed to work at 4G under 800MHz (thats what the specification states) i cant manage to make it work. I have perfect 4G coverage, 4G sim, 4G tariff, even gave my sim to a friend with S7 edge and it worked on his phone. Maybe new update will fix that? I tried with different sim from different operator (LYCA) and it works but 4G in LYCA is at 2100MHz so I didnt really check the 800. I tried everything and still nothing. Did anyone have similar problem?
I actually bought 2 phones of the same model so I decided to check if 4G worked on the other one and as I put the sim card in I just remembered something and realized same thing happened with my phone. When I put the SIM card in for the first time it DID automatically go to 4G, ok, when I looked for available networks it found O2 4G, granted BUT!!! when i got to "preferred network type" there is only 3G to pick, and THE MOMENT I PICK IT there is not possible to go back. Every network I find from that moment is only 2G or 3G. Now i reckon that a software problem right? See attachments
It is a software bug and I think I sort it out after flashing the phone. For now I sorted out the problem using Networks app by Philipp Mangalov and switching network to LTE/GSM auto
Well it seems the data part of the UMI SUPER is not so super, is it? I face a similar problem but worse. The 4G band of 800 doesn't work(despite being advertized by UMI as supported) but luckily the band of 2100 works without any issues. The problem comes when I'm out of 2100 band coverage and phone must switch to 3G - then I lose all data connectivity completely. So basically whenever I'm out of 4G 2100 coverage(which is often) I am without any connectivity! Anyone facing the same? Solution?

I only have 3G and the phone shows that I have internet, but when I try to actually use the data it just says no connection on apps.

Hi,
did anyone using Umi Super have any problems with using 4G at 800MHz? Im on giffgaff and even though Umi Super is supposed to work at 4G under 800MHz (thats what the specification states) i cant manage to make it work. I have perfect 4G coverage, 4G sim, 4G tariff, even gave my sim to a friend with S7 edge and it worked on his phone. Maybe new update will fix that? I tried with different sim from different operator (LYCA) and it works but 4G in LYCA is at 2100MHz so I didnt really check the 800. I tried everything and still nothing. Did anyone have similar problem?

I don't have this issue at all. My UMi Super connects perfectly to my 4g network under 800MHz without an issue here in Uganda. You can install the MTK Engineering app from the play store and check the band compatibility on ur device and you can also set the mode using the same app under android settings.
You could also try updating to the latest OTA which is 20160810 or the one before it by downloading the files from forum post here and saving them to ur phone and updating manually if you don't have the current OTA

GravityBox is a perfect solution for this problem. You can set up an icon in notification bar allowing You to toggle between 2G/3G/4G

I actually bought 2 phones of the same model so I decided to check if 4G worked on the other one and as I put the sim card in I just remembered something and realized same thing happened with my phone. When I put the SIM card in for the first time it DID automatically go to 4G, ok, when I looked for available networks it found O2 4G, granted BUT!!! when i got to "preferred network type" there is only 3G to pick, and THE MOMENT I PICK IT there is not possible to go back. Every network I find from that moment is only 2G or 3G. Now i reckon that a software problem right? See attachments

same problem
This is indeed a software issue, one I have come accross many times - using an app to toggle between the service types is the best workaround!
There are many apps that work to resolve this, some great ones have already been mentioned.

4g Umi Super on Giff Gaff
You need Giff Gaff settings in access point name. If you try and use O2 4g it doesn't work even though Giff Gaff uses O2 network. Settings are really easy to input but MUST be Giff Gaff not O2.

All that's needed is GiffGaff settings inputing manually. Very easy to do. O2 settings that the phone recognises when a GiffGaff sim is used WILL NOT WORK. The Network is O2 but the APN settings for GiffGaff are totally different.
All you guys that think you know what you're doing obviously don't.
No need to Root or use GravityBox or any other App.

Well said. I just shake my head in despair when I see how totally clueless people try to be teachers and Internet gurus with very limited knowledge about the task at hand. These comments should come with warning stickers.
For those who want to be able to switch between 3G/4G and LTE only, use this nifty little APK that I've attached below. It will allow you to enter engineer mode without using the dial code.
Hi
This is a bug implemented in Android 7.0.
I had the same.
1 Just force in your parameters 2G/3G networks
2 wait for network authentification (no more excalamtion mark)
3 go back to 4G
Every thing will be OK to next switch off or plane mode.
Rgds,
LTE band 7 (2600) not working
I recently received my new Umi Super and updated to the last firmware V7.01_20170413, everything works fine except for the 4G. I live in an area where band 7 (2600) is available but the phone can't connect to it. Of course, my preferred network type is set to 4G/3G/2G (auto).
I read a lot about the issue on the internet but I can't find a solution.
I checked the BandMode on the phone by dialing *#*#3646633#*#*, band 7 is included and checked. However, when I tried to remove the other LTE bands and keep only band 7, I got a message explaining that the list can't be empty ("Failed. The band is changed from not null to null, it is illegal"), though the list was not completely empty because band 7 was still selected.
Also, I tried to change the radio band by dialing *#*#4636#*#*, but process com.android.phone stopped working when I pressed "select radio band", even after I cleared cache in phone and sim apps.
Can anyone tell me how to fix the problem and get connected to 4G.
BTW, Network by Philipp Mangelow is not available anymore. Switching between 3G/2G and 4G/3G/2G settings doesn't fix the issue. I tried the giffgaff settings, but the APN gets deleted as soon as I try to save it.
Thanks

You may try to force 3G and then try to force 4G
You may try to user another IMEI number from a UMI device with 2600 support (of course backup/write down the original one before just in case)
http://www.ucc.co.ug/data/imei/2
After the update to Nougat 7.x how long does it take to do a full recharge?
Do you still have fast charge feature (< 1 hour) or do you lost it like all users reported so far?
What about your GPS? Do you have a fast fix after cleaning history and is it reliable (not losing signal often?).

Is it safe to change the IMEI number? and where can I find another number for a UMI device?
GPS is working fine, it fixes pretty fast, but I'm not sure about interruption in the signal because I haven't used it enough yet

Any way to get 4G/LTE, Please Help!

Hi everyone. I have a Leeco Pro 3 X727. I am on Firmware 20s I am having issues to get 4G/LTE signal.
First thing, In my City there is 4G signal, even a couple a days ago I went to my carrier and change my Sim for the newset, just in case.
The last Rom where I had LTE signal IICR was AEX5.4 around May's days. After I changed to CDroid, then to DotsOS... Whatever all I can get its H+ signal. Couple a days ago I change to Carbon Rom 6.1 (Oreos) and the first install, in the configuration I get LTE, but after change to Wifi for finish install all apps, I cant get LTE again. I flashed back Dots, Cdroid and I am now and AEX5.7 and I I have the same issue, just 3G/H+, not LTE or 4G. Also, after flashing firmware 20S I get LTE signal for a While so I think that is not the problem...
I tried almost all APN setting and Nothing. Chang Rom, change Recovery, change Kernel... Nothing just 3g/H+.... My friends with same Carrier have LTE signal...
So, is there anything I can do...? Flash any app, setting?
Help please.

Only use the X7272 5.8.20s firmware - Then you should be able to get it with the correct APN and setting
Don't choose Global, you want the LTE/GSM/UMTS/CDMA setting. If you are still having issues, use the program LTE Discovery or Network Guru.
There are Magsisk
What network are you trying to connect to? What country are you in?
Go to Settings -> Backup & reset -> Network settings reset -> RESET SETTINGS

Nothing. Still "Orange 3G" and conexión icon show H+.
Honestly, I'd say something is wrong with your phone or wrong with your cell towers. The only LTE Band that Orange/Altice supports in DR is B3 (sorta strange that there's only one band, but for a relatively small country I suppose it doesn't matter) and the LEX727 and LEX720 both have band 3, as well as the only GSM(3g)/UMTS(4g) bands that Orange/Altice supports (that being GSM:1800/1900 and UMTS B8 (900GSM)) At first my assumption was that Orange/Altice was a CDMA network, but as far as I can see, there are no CDMA networks in DR!
Edit: download the speedtest app, and see if you're getting the same speeds as a phone that shows it's connected to LTE. If you are, there's no issue besides the phone reporting the connection wrong. If you're slower, though...

Maybe the problem is Orange Altice. The 4G coverage its very new in my city. I al ready tested speed and its 3G 5mb/3mb
Thanks for answering!

Oh! I think I know the issue! When I looked at Orange's website (trying to find network specs, which strangely for a network that supports BYOD, they don't have listed, or at least I couldn't find it) I saw that they have subscribers pay for data, as is standard practice in the US (where I live). But the thing that caught my eye is that you also pay for speed.
So... Let me take a guess here. You pay either RD$1499 Or RD$1349 for their 5mbps unlimited plan?
Basically, my assumption is that if you're paying for one of their lower speed tiers, they put you on a 4g or 3g network to save LTE bandwidth for the people who pay more than you.
Tell me if any of this sounds familiar... I feel like I may've found your problem!

Mmmmm suspect ... actually I have an even lower plan, RD $ 580 (USD$12) and I only use the data when I buy additional packages ... Most times I use Wi-Fi and just use Data when I am not at home/job and the 3G its veeeery looooow speed... Thank bro, that could be the problem.
