I have XTZ SO-03e and I cant get a LTE signal on stock docomo firmware but after debranding(sgp321 firmware) it my LTE is working fine.. After flasing bAck the docomo firmware excluding the system to get my 32gb partition back I am unable again to get an LTE signal.. I think that the LTE signal in stock firmware for so-03e limited only for japan. Any suggestions to Make LTE signal work on docomo firmware or after flashing back the 32gb partition would greatly appreciated thank you

how can i make my phone work with T-mobile in Usa, i Have unlocked it but i dont know if i can make it work with Data because i have read that it's impossible to make it work with data on 3g. My Phone is S5830L and i have the kp3 modem from telcel.
You need to see the UMTS frequency that T-Mobile uses, I think it's 1900, so, you need to use the baseband for that frequency.
What rom are you using on your phone? You could try this one: http://forum.xda-developers.com/showthread.php?t=1399917

I got myself a MediaPad S7-302u on Tesco Thailand yesterday, and the first thing I did was to update the firmware to the International ICS available on the website. New firmware is great, all is working, I might change to a "modded/tweaked" version here from XDA like I do on my Galaxy S2, former Galaxy S, gf's Galaxy 5, etc...
Little problem... apparently the version on the website is for MediaPad S7-301u. Only difference between them seems to be frequency of the 3G networks. The tablet is working beautifully, GPS, mobile data, etc, EXCEPT for 3G, in the network I use, AIS/1-2-Call. I don't have a big problem in using Edge, I do the same with my S2, to save battery, and I don't care about the reduced speed (Edge here works well, I get usually close to the 384kbps max speed), but I'd like to have the option to, eventually, one day... go to 3G. The problem is that I can't seem to find ANY firmware versions for the 302u!
Any idea where those are hiding? Tks!
Install huawei mediapad Russian version which was released on 30th May, it solved my 3G issue with my network.

Thank you supun, but unfortunately it hasn't changed anything here. Still only on Edge, and no sign of 302u file on Huawei website.

Interesting. The 303U is the T-Mobile Springboard which is what I have.
I have two SIM cards in Canada with different 3G-only carriers, and a 303U Springboard unlocked from T-Mobile. One carrier uses AWS 3G (same as T-Mobile) and the tablet sees the network but cannot connect to it at all. The other carrier uses 850/1900 3G and the 303U supports 1900 but not 3G, so it does get connectivity with occasional dropouts.
I was never able to connect to the AWS network before the upgrade but I didn't try very hard. After the ICS upgrade I have still been unable to get on the AWS network and I tried in-store with a SIM from another AWS network too, to no avail.
From before the upgrade, I did capture an update.zip that seems to contain modem files for the T-Mobile Springboard, but the last time I tried to flash modem files directly I lost my IMEI and SIM unlock until I did a full reinstall of ICS.
Not sure either about 302U firmwares.
I just read on development forum a 302u ICS firmware has just been released. I might try that one later, it's just quite annoying to lose everything on every flash, specially on stock ROMs, with no root.

You can add root to any ROM. Download the CWM-based recovery from here (note it does NOT do backups properly so you can't rely on that):
http://forum.xda-developers.com/showpost.php?p=23601045&postcount=7
And also place the SuperSU zip from here on the root of your external SD card:
http://forum.xda-developers.com/showthread.php?t=1538053
Flash CWM in fastboot as described, to both recovery and recovery2, and then you may have to try a few times to get into recovery. From a totally off state, hold down the volume "UP" key (which is the one pointing AWAY from the power button) and hold down power until it vibrates. Let go of power and hold on to the volume key. Then in CWM you can find the SuperSU zip on SD and flash it. Now you're rooted and you can take a Titanium Backup.
BUT if you ever want to do an official upgrade now, you will need to revert to a stock recovery. Take the recovery.img from any ICS firmware package and flash that in fastboot to recovery and recovery2. Or if you are every currently on an HC ROM you need to use an HC recovery.
Something else to try... worst case scenario is you'll have to wipe anyway. Download the Huawei firmware zip, extract the dload directory, and then open the update.zip. Delete the userdata.img.ext4 from that zip. Put the modified dload directory on external SD and proceed as usual. If it installs correctly it should (I hope?) leave your data partition alone.
According to member cmstlist below are the different between huawei official releases.
302u is an 850/1900/2100 version
301u is 900/2100. T-Mobile Springboard is 303u
AWS/1900/2100. AT&T's is 312u.
I thinks because of using wrong FW updates some times experienced 3G/HSPA issue.
Should I ?

Can I quickly hijack this thread.
I have the 7A-301U. (Orange Tahiti UK) that came with ICS (Andy4). Works perfectly BUT abruptly stops ringing after one second on attempting to reach any 3G Signal Provider. (correct Orange EE sim inserted) . Similarly, if I attempt the simple task of dialing for my own IMEI ..... #06# Question: Should I re-Firmware from the Huawei site.
Ciao,ringrazie salute.
There's a new Mediapad s7 302 firmware on Huawei site (Dec 13). It says network function and official release version. It's still ICS.
312u = 302 ?

Can I use the official 302 Firmware in my AT&T 312u?
I have a DoCoMo SO-03E and also an SGP321. I have successfully de-branded the SO-03E to an SGP321. Comparing the two tablets, they are identical (after applying the old firmware system to get the 32Gig partition back).
The only issue I've hit has been with LTE in that it has maintained the DoCoMo LTE "working bands" as viewed from the hidden system menu which are 1, 19 and 21 which aren't applicable here in Australia! So it appears that the LTE working bands are part of the firmware of the SnapDragon chip (which has an integrated radio) and hence not changed via the FTF image.
Does anyone know how or if these can be changed via an API/SDK from Qualcomm (if possible) so that the true SGP321 working bands can be applied to the SO-03E to convert it to a true SGP321 with 32gig of internal flash? Looking at the snapdragonS4 pro data sheets and looking at the Sony description of both tablets that state they both use the Snapdragon S4 pro, I would think there is some EEPROM or memory address that could be updated to tell the SnapDragon that it can use the other LTE bands!?? Maybe Sony has the Snapdragon chips configured in batches - those for DoCoMo with 32gig internal flash and those for the rest of the world - SGP321?
Any ideas as to whether this is possible?
Im in your shoes to!
My DoCoMo is debranded with sgb321 and would love to be able to use LTE instead of 3g
I did read somewhere tho that a part of the hardware is different and isnt possibke to do what u want.
Letz hope I read wrong!
If there is an SDK available and the memory space which holds the configuration details for LTE is available then it may be possible. If not, we're stuck with the DoCoMo LTE bands
I was so hoping the firmware re-programed the radio. The issue is the radio is integrated into the Snapdragon S4 Pro chip and not a separate chip.

How did you manage to debrand the SO-03E?
I tried to flash the SGP321 firmware onto my SO-03E with flashtool but it wouldn't flash.
I have successfully flashed the tablet a couple of times using the flashtool. The last time excluding system with the latest so-03e image to get the 32gig partition back..
what did the flashtool say when you tried to flash the new firmware? Mu tablet is locked and not rooted.

I can't remember what the error was it was a while back when someone first posted the SGP321 firmware. it must have been a bad file or something, I just downloaded the latest firmware and flashed and it worked.
Can you explain how to get my 32gb partition back? do i just flash the So-03e image and tick system in the exclude section, and I will still be on sgp321 stock firmware but with 32gb partition?
thanks for your help!
yep. flash an SO-03E image and make sure you select "system" to ignore

thanks! will try that tonight!
as for the LTE bands, no one seems to even confirm if the hardware actually supports the other bands, and the tablet z doesn't seem popular enough for enough people to look into this. let alone the s0-o3e is even less common.
fingers crossed!

Looking into the specifications for the Snapdragon S4 Pro, the LTE radio is included in the chip which means that its actually in the Snapdragon code, not Android. Hence, if there is some EEPROM memory somewhere on the chip that allows for the programming of the LTE bands via a SnapDragon Software Development Kit (SDK) then it may be possible to update/change the bands. This would take some serious low level knowledge of the chip. I actually started looking at the Snapdragon data sheets and sdk examples and unfortunately no where did they mention changing settings for the radio..... I think there would be some demand for the ability to do this as the SGP321 doesn't support the LTE bands of some of the USA carriers... Supposedly the Qualcomm radios are the only ones at the moment that support ALL LTE bands... Obviously device manufacturers and carriers can limit the LTE bands which makes me think there are no different flavours of the chips and that it is the device manufacturers that are selecting/locking the bands.
Hi guys. I've a question. There's a way to unlock LTE bands on g850Y? I've bought my phone in Chile, but in Argentina LTE doesn't work on the same frec.
On theory, Panama's ROM for G850Y should work in Argentina's LTE frecuency, (band but i'm not really sure to flash, and i'm not sure if i'm doing something stupid and end up with a soft brick.
If that's possible, could someone explain the steps for flashing? (If i have to do a complete flash, or just modem.bin.. etc)
I need a ROM that get's BAND 4 AWS.. is any of this possible?
Thanks!
Same here
I have the same problem, if anyone can help please.
Hi, I need help.
So, I bought 2 moto E 2015 model (at&t unlocked) from Ebay - very cheap.
But this phones working with only 2G mode in my country (even theese are LTE models ).
I want to reinstall system to better one - which there is no any at&t default applications or any of carrier applications.
And I also want to change baseband versions - because, this phone working only with 2G network type with my country's mobile carriers. I think it should be for baseband (network standarts) .
is it possible to fix problem with change firmware and baseband to no-contract version?
I asked my mobile carrier, they said, "we are using 900-1800 MHZ for GSM ; 900-2100 for 3G, 2100 for LTE (up to 2100)
Who can provide how to and links?
Thanks.
The AT&T model cannot be bootloader unlocked, so you cannot change the firmware to another version. There's a guide in the General forum about enabling additional LTE bands, you can try tweaking it for 3G, but there's no guarantee that the AT&T model's antenna hardware can support those bands.
