[Q] SO-03E - changing working LTE basebands? - Xperia Tablet Z Q&A, Help & Troubleshooting

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.

[Q] Firmware version, modems, etc (301u/302u)

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!

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 ?

LTE bands unlock E2363

Hello all. I'm wondering if anyone here has tried to unlock additional bands on their M4...or more specifically E2363.
I purchased the E2363 but didn't initially realize that it does not support any LTE bands for US carriers (t-mobile and ATT)
I was thinking of using this guide to unlock the bands. However, I wanted to check first because can still return the device for a full refund since I have not opened it yet. I WOULD just purchase the E2306 model, which should work on USA LTE bands, but it is hard to find and much more expensive.
http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031
Any advice?
And how do you plan to follow that guide if you don't have root access to enable diagnostic mode? Root is required and at the moment there's no way of obtaining root access in M4 Aqua...
I guess I hadn't realized that it was not rooted yet. But I figure it should eventually happen right, or it is looking like there will be no exploit found?

It's a cat and mouse game, we'll find an exploit to root, Sony will fix it in a new update, we're going to find another exploit and so the game will continue. Also, when you get root, you'll probably have more luck using the unlock LTE bands from Sony cross-device section that is made especially for Xperia devices...
Hi, this is exactly the problem I try to resolve these days. I accidentally bought E2363 too and it does not support 800 MHz which is the only relevant band for me.
Are there the same chipsets in all devices so they support all bands and you only have to activate the relevant for your area and possibly deactivate the rest?

LG v10 korean version-flash or not

Hi to all!
This is my first post here.
Couple days ago i purchased LG v10 (F600L) with 64GB of ROM! This is korean model from network U+.
I live in Croatia so I can't use some features from phone, and it's not the major problem.
I wonder if is possible to flash phone with H960 firmware? Via LGUP app from my PC? Is it problem because my phone has no unlocked bootloader and in some posts on the internet I readed I can brick up my phone.
4G does not work either. Probably only korean version of LTE, not supported in Croatia.
So, if I do firmware upgrade via LGUP, with euro-version, will I get phone with only 32GB, will LTE bands be opened to euro-networks?
I didn't say that I can't upgrade my korean version to Android 6.0, via OTA or LG Bridge. It says Cannot check the latest firmware.
So, guys, to do it or stay out of any attempting?
Thanks and regards from Dubrovnik!
Is it true that noone knows?
Cannot, ne mozes! Just try to read a little more about it.
If you click the link you can see there is support for 4G in Croatia.

I can see Croatian operators can offer me LTE 1800mHz only.
So, in suburbs of croatian big cities I have LTE, but only in streets, outside places etc. Whei I enter in some bar or restaurant, LTE wanishes.
I'm on VIPnet Croatia which provides LTE 800/1800. It seems my Korean V10 works only on 1800.
Too bad. Cause, it's good phone. I upgraded recently to Android 6.0 (MM) via link on this forum and it works even better than on 5.1.
On posts on this forum(s) I can see that my device cannot be flashed with another firmware. I've downloaded Turkish version (64GB) but LG UP says Error. It seems I have to root my device, but even than, it's not for sure that all LTE bands will working.
Koreans made the mess by locking with brandings their devices.
@moby77: for what I know, you can't flash a different firmware... a brick is nearly assured.
But you can try this code: 5457#*600# then go to Multi Band Selection and check LTE bands that are available in your Country.
Don't know if that procedure works in your device, but it well worth a try!

I am not sure but most probably flashing wrong firmware will brick the phone. However, one thing I am sure is just flashing the firmware on different version never unlocks the bands of 3G/LTE. These bands cannot be unlocked this way. If F600L does not support a particular band in your country, it will not run LTE no matter what firmware you flash.
F600L is very well locked by Koreans so I san't do anything except flashing new kind of firmware, but one provided from U+ network.
One day I got mad, so I used LG UP, downloaded firmware for Turkish H960, and pressed Start button (it really was pissed off so even I bricked phone, my fault. Totaly insane, but...). After 4% od doing "something" it said Error, cannot flash firmware! (or something like this).

you have H901-10c official os bcz when i upgred using LGUP my phone is not starting as well as not showing charging sign when i am connect my charger

N9 LTE Radio vs N7 LTE

I flashed the full NPF26F Google image over NRD91N on my N9 LTE (volantisg) . My current baseband version is 0.09.30.0105_0055. Can someone please confirm this is the current radio for the N9 LTE version?
Also, could someone please help explain the difference between modems in the N9 LTE tablet versus the N7 LTE tablet? For the N7 LTE (and Nexus phones), the Google image file contains a radio.img and the devices have a modem partition that can be flashed separately with this file. Using Fastboot, I've been able to change radios on several Nexus phones I've owned, as well as the N7 LTE. The N9 LTE tablet is different. It has no visible modem partition, AND the Google image file contains no radio.img.... So the question is how are the modem drivers updated? Is modem located within the bootloader partition and updated with bootloader.img? Is this just due to a manufacturer design difference between HTC and Asus? Thanks.

What would happen if I flashed the USA SG771 (LTE) firmware to a Z4V phone (E6508)?

hey Folks,
I have, in my possession a real live Xperia Z4V (E6508) that is Verizon branded. Internally it is almost identical to the Z3+ phone with two exceptions that I can discover
1. CDMA Radio
2. UHD 2560x1440 Display
Seeing that the Z4 Tablet is almost identical and has a 2560 x 1600 display, what would happen if i flashed (locked bootloader so Flashmode only via flashtool) a Z4 Tablet STOCK firmware that includes LTE support?
Any chance this will work?
Since I cannot find a STOCK Z4V (E6508) ftf or any image at all I have some reservations about the attempt.
If it would work, which firmware would be appropriate? I have working ADB/Fastboot and Flashtool installed so I would D/L the actual firmware image via Xperifirm.
Opinions? Suggestions?
Thanks,
Rick

Interesting.

IMO the chances flashing will work are zero. The hardware is too different.
Use it as a webradio or something along the line.
If you flash without means reversing the flash it will become a paperweight ...
Ummm the hardware is almost identical.
