Stock firmware for Huawei E5776

Hi
Does anyone have stock firmware for Huawei E5776 in English please.
My E5776 was showing NO SERVICE after unlocking from EE no matter which SIM I used so I updated it to a newer firmware version but that turned out to be some Russian network's firmware and moreover its in Russian language.
Is there anyway that I can revert back to the old EE firmware in English or update it to stock firmware if available.
Thanks

I have the same request.
I buyed my Huawei to ebay from UK but unfortually the modem wasn't a stock firmware but EE mobile firmware.
My modem is unsimlocked but I need stock firmware also because the modem is in roaming because I use it in France with Bouygues Telecom operator.
I use correct APN but WAN refuse to connect...

Got the same one with EE firmware, it reports that it's in roaming, but after setting up APN and connecting manually (or marking the connect in roaming checkbox) it works fine.
But I'm also interested in getting the stock (or other than EE and english) firmware.

Someone tried german updater?

Same for me, but we cannot use roaming protection in our country...

Found stock firmware/dashboard for my E5776 from ee.co.uk!
And it's working fine - here's a screenshot which proves that:

It's on german huawei site: http://huaweidevices.de/e5776?show=downloads but it's multi-language!
There's also pdf with instructions - first need to install the Update_UT* (drivers) and then the e5776_Update*.
If it asks for flash code, you can generate it here: http://www.modemunlock.com/huawei.php

firmware / version
hi
is this firmware compatible with all versions of e5776? mine is e5776s-32...
really hope so

Yes, it is
Hi,
Yes, I have just updated mine which was an EE branded, all is well happily connected to three using the stock firmware.
If yours is an EE one too then don't forget to get the firmware update password from that site in the post mentioned earlier.

what's EE? an network? i'm from Portugal... and mine is from a different network... 'll it work?

Likely to work
Yes, it is likely to work.
EE is a network in the UK.
The stock firmware is coming form the German Huawei site.
It did work for my device, at any rate, there are no guarantees.

No nothing to worry about. That is just the location of the JS served by the router. (It will not run, when you click that link.) But since yesterday I also need these:

No problem, just go to the page:

and then (if you use Firefox) hit CTRL-U. This opens a new browesr window with the pure HTML code, without the JavaScript modifications, so that you can copy & paste it.

Update and lose 4G
I recently followed the instructions on installing the stock firmware on my OPTUS 4G E5776. All seemed right, I had the Huawei dashboard, but after doing this, all I can connect to is to the 3G network. It seems that if you use the stock firmware, you will lose the ability to connect to the 4G network. Has anyone else had this problem? Is there a way to set is so you can still get 4G? I have searched high and low and could not find anywhere to download and reinstall the OPTUS firmware again so I just returned it to where I purchased it from for a replacement. I am not game enough to do this again until I know I can get 4G, as this is the reason I purchased the 4G modem in the first place for better and faster speeds.
Thanks

4G Connection
@Brad1982
Someone who followed the instructions on my website to update the firmware just got in contact with me today with exactly the same issue (on the UK EE network).
To restore 4G connection go to the connection settings page and switch from Auto to 4G only and save setting. The modem will now connect correctly. Once connected for the first time you can then switch back to Auto and 4G should still work. Why this step is necessary is a bit of a mystery I'm afraid!

drops connection
I followed this thread to unlock and install the default firmware, all went ok but I find that it drops connection frequently. I change settings to 3G only and manual connect which seems to help but it still does it, any ideas?
I have seen some of the bugs mentioned here also:

Get VoLTE working on H8314/H8324 XZ2 Compact in India on Airtel and Jio

I spent quite a bit of time figuring out how to make the VoLTE work on Airtel and Jio in India on a USA edition H8314 phone.
Sony for some reason doesn't bundle all operators VoLTE configuration in all images, not sure why, typically not the case with other high end phones. And they have region specific bundles or OEM customization.
I solved the problem by taking parts of the regular dual sim ZX2 firmware H8296_Customized IN_1314-9934_52.0.A.3.202_R4B, which has the VoLTE configuration for Airtel and Reliance, and flashing it on my phone. VoLTE works! No issues noticed so far (will update if I notice anything).
Here are the steps:
1. Install XperiFirm
2. download the Indian version of firmware for XZ2 dual, in my case H8296_Customized IN_1314-9934_52.0.A.3.202_R4B
3. download and install newflasher
4. From the downloaded and extracted set of files in XperiFirm download directory, copy the following to another directory
oem_other_X-FLASH-CUST-B6B5.sin
oem_X-FLASH-CUST-B6B5.sin
5. Copy the newflasher also to the same directory, now this directory should have 3 files
6. turn off the phone,
8. enter flashmode (vol down + connect USB cable to PC)
9. run the newflasher, in the directory you prepaired in step 4 and 5
10. Unplug from USB after the flashing is done and restart your phone, it should work with VoLTE on airtel as well as Jio. On airtel it may take a few minutes before the calls actually start going on VoLTE but it works perfectly fine.​
This doesn't require bootloader unlock so all phone function would remain good. Feel Free to ask questions, the version of firmware on my XZ2C is 52.0.A.3.163 USA generic.

So this works good with Indian and US networks ?

I haven't traveled to USA since, but I do not see why it won't work.

thanks ahzam for sharing this. My XZ2 is on Customized Version CE1 and VoLTE didn't work with o2 Germany. I downloaded the DE firmware with xperifirm and flashed the 2 files you mentioned via newflasher v13. Reboot and everything is working fine now!
Thanks again,

Hi ahzam,
I have bought H8296 unlocked international version from USA.
I am also not able to use the VoLTE in India on airtel idea or jio.
Will this firmware help me to get the VoLTE.
After doing so, will I be getting future official Sony updates or it will be rooted device and Xperia support will end?
Can you please help?
Regards
Akhilesh

For me updates still work.
Your device will not be rooted after that. So in my opinion you will not loose your warranty.
Greetz

Thank you for confirming
I will try this and keep you posted if this works

Thank you Guys
It worked and now I get VoLTE on both Airtel and Jio.
However for Airtel it takes some extra 10 seconds to get VoLTE.
One problem I have noticed after this. I received an official xperia update but got an error "Could not Install" while installing this update.
Do you know how to resolve this issue?
Regards
Akhilesh

For me all updates worked so far without any error. I think i've read somewhere, that the update can be done via Sony companion. (But for me companion never worked in any way^^)

you should be able to get VoLTE for any region by following this process, you need to extract the files from right version of the bundle for that region.

hi, actually I'm using xz2 premium (H8166) which isn't supported by the jio sim and airtel volte so can I try this method? Thanks.
updated : actually, it's working for xz2 premium so no problem in Volte... so rite now Im using airtel and jio both working fine... but mobile restarts for network optimization while changing mobile data from sim1 to sim2 or sim2 to sim1. Anyways thanks Alot for this awesome tip man.. I really felt bad for my xz2 premium now I'm really happy. You saved my money. Thanks again.

First of all, I would like to say Big thanks who share this Procedure, Now I am able to use Volte Functionality
Now I have the same problem while changing sim1 to sim2 to and vice versa but before did volte procedure it was working fine in both sim, so as per my opinion this problem related somewhere Volte functional
I bought this Cell from the Middle East, So in Middle east it was working fine while changing Sim1 & Sim2 Procedure and even in India it was working
So if someone does R&D than might be it is a curable issue, I don't know why Sony did a big mistake nowadays even Oops, Vivo, all Chinese implements successfully these things, even sony dosnt implement Auto Hide status bar in Compact Series Cell

Today I discovered 3 more problems
1)After Install Volte Firmware, Because in India no Official launched XZ2C , after install we can not get Firmware Update
2)If you Switch Mobile data between two sims, Cell will restart automatically
3)In Setting->Display you can not get Super Vivid Mode or Professional Mode for better color reproduction
So if anyone tells me XZ2C officially launched which country with Volte Function, if we get an answer than we can solve all the issue

Fact. reset

To get back this, just factory re-set and will get this options. Anyway It is not working any VoLTE (it's just showing the LTE symbol and option in seeting, in reality your call is routed on 3g/2g. ) you can verify this by selecting 4g only and try calling.

Can you tell me which Firmware you are using, because I am not able to get any OTA Update

https://xpericheck.com/device/H8296
Current build is 52.0.A.11.3

At&t branded phones on Tmobile network

My wife works in a hospital and we used wifi calling because reception was poor.
It's still poor with Tmobile but no wifi calling. When we moved from At&t the wifi
option was greyed out. Tmobile states that it works fine on their network.
Is there any way to get a samsung s7 g930a and a samsung j7-j727a to use wifi calling
on the Tmobile network?
I'm sure it will probably involve something over my pay grade but I am willing to try
anything needed to get this feature to work

If your current firmware has WiFi calling (Volte) You can only use Volte if the network supports it. There are however many apps you can use for WiFi calling look on the play store.

Not sure what volte is, I have had some other issues with the
service that I thought might be resolved by installing a
different rom
Tell me if i'm wrong
Thanks

Volte is wi fi calling over a network which the network operator supports without the need for a specific app.
Please tell me exactly what you are trying to do
What network are both phones using?
Which networks were the phones on initially?
Have you modified the phones in any way? Root? or TWRP?
What firmware are both phones currently using? Go to Settings>about phone>software information>baseband version G930A????

Sorry for not getting back sooner
Both phones are currently on Tmobile network
Both phones were originally on At&t network
No modification
Samsung s7 g930a baseband version G930AUCS8CRL1
Samsung j7-j727a baseband version J727AUCS4BRL1
Note: Wifi calling was available on original at&t network but is now greyed out on tmobile network

Ok since wi fi calling is network specific (some have it some don't) you either need to have unbranded firmware on your phone so it works no matter which network is providing it, or you need to now flash T Mobile firmware for it to work again on your phone.
US networks are a nightmare when it comes to this sort of thing and it's a right pain in the a** to solve it. So what you need to search for now on here is how to flash different firmware on AT&T S7. You should always try to flash unbranded firmware so everything works easily, if not it will have to be T Mobile Oreo.

Ok, If you think unbranded is the best way to go can you point me in the right direction

updato.com and sammobile.com both host firmware and have flash guides. SamFirmTool also is good for downloading firmware, but only lets you download the latest version and isn't as user friendly.
For unbranded you'll want to look for G930U firmware.
For best compatibility you flash all 4 files using (AP,BL,CP,CSC) this will wipe the phone clean. Otherwise you can try Home_CSC instead of CSC (So AP, BL, CP, Home_CSC) , which keeps your data but may not fully resolve your issues.

What beanvee has said but I think it's worth mentioning I find Sam Firm tool pretty straight forward to use and you'll always get the firmware in separate parts which can be useful.

I found a link for the G930A here
I'm not really understanding the differences in firmware. How is flashing with this firmware
any different than what's on the phone right now?
I am just trying to get the wifi calling to work, How is flashing it with at&t version firmware going
to help me on the tmobile network.
I guess I don't know what I need, stock, unbranded, official or custom rom.
I checked all sites listed and there is no firmware for the J727a, alternative?
I would rather someone more knowledgeable guess what I need to do, if that is what is
necessary because the phones are no good to me without that feature. Any suggestions
would be appreciated.

Each carrier deploys their own CSC file, which contains carrier specific configurations, and its this file that determines if VoLTE or VoWIFI is enabled and how it connects.
AT&T may have different VoWIFI settings to TMobile, which is why using AT&T firmware it doesn't work. Some carriers outright disable it since they don't offer it.
Your best bet would be G930T firmware https://updato.com/firmware-archive-select-model?q=SM-G930T&rpp=15&order=date&dir=desc&exact=1
However unbranded G930U should also work because the unbranded firmware is meant to work on all cariers. G930A would likely get you no where since it'll be AT&T specific
The phones in the USA are all identical hardware under the hood, the only difference is the carrier branding and firmware.
But that's only for the S7, I'm not familiar with the J7.

And it's not through lack of knowledge @JohnAtlas, US phones are a nightmare to do anything with. There are several options available but it's difficult to explain what to do and how to do if you are not familiar with how the software works.
There are many guides on how to unlock the software on all US networks, and depending on the network can include multiple steps to complete, you just have to search and read.

Ok, I was able to find the latest firmware for the G930 phone
I installed odin and have the files, BL, AP, CP, and CSC or Home CSC
My question is, Do I load all files and then start or do one file at a time in odin
I tried all files the first time and got failed error and dismatch
Thanks

All files in correct slots and use this Odin https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572

Put all files in and used patched odin via link
Received fail and screen that said, "An error has occurred while updating the device software"
After reading more, tried to install twrp and received secure check fail : recovery
Rebooted phone and this is the screen right now, not sure what to do next

That is the system recovery and when you flash with Odin you need to put your phone in download mode first press volume down+home+power. The phone should not go to that screen you have posted either before or after Odin, its a completely different recovery mode.
Get your firmware from updato. Com or sammobile
G930U, filter by USA and choose the latest XAA or USC and use the modified version of Odin. We know this works because thousands of people have used it to do what you are trying to do.

Thanks for info, I used G930U TMK version since we are on Tmobile carrier
It seems to be working fine and wifi calling is available
There is no TMK version for the J727U but will try the XAA for the other phone
The way I understand it is that the U means unlocked and the XAA is generic and not carrier specific
Please advise if I'm not on the right track
Thanks for your help

That's brilliant , glad your up and running.
So the letter "U"after the "G930" denotes the region of the world the device is build to operate in, the Americas just happens to be U. The unbranded firmware is the one that has a region but no network assigned to it, so a 3 letter code is used instead, in your case its USC, or XAA.
Europe is G930"F" or "FD" and the 3 letter code for unbranded is BTU & XEA.
Anyway if your phone is running great on T Mobile then don't update it anymore, turn auto update off. The advantage of keeping it T Mobile is you have the wifi calling, the unbranded firmware needs more fiddling around with the get the wifi calling working on the network your using, so best to stick with what works.
I will have a look for firmware for the J7 you have to see if i can recommend doing something with it to get the wifi calling working.
*update*
So it seems the J727 is the same as the J7 in terms of the internal components, everything is the same in both models so that's great news. I think the "27" bit is just a marketing thing.
In theory you should be able to flash the latest T Mobile Oreo to your device from this link https://www.sammobile.com/firmwares/galaxy-j7-pop/SM-J727T/TMB/download/J727TUVS4BRK1/249137/
Now before we start please check / do the following to avoid further problems.
1. Save everything you need from the phone to your pc.
2. Check that you have OEM unlocked in "developer settings" and "USB debug" enabled.
3. developer setting menu is, settings>about phone>software and information>build number>tap 7 or 8 times, developer menu should now appear. (Sometimes it's somewhere else but build number is what you want to find and tap on 7-8 times).
4. To avoid any issues with device FRP lock, delete your google account off the phone., settings>accounts>google. delete it. When successfully flashed you just add the account again when the phone starts for the first time by signing in.
5. Use the same version of Odin you used to flash your S7.
you can also use updato.com (i think it's slightly faster than sammobile.)
Let me know how you get on.
Remember J727T (TMB) is the firmware you want.

Since CSC change is not possible with latest UI 3.1 update what are options to change CSC

HI all,
With CSC change not possible using codes with latest UI 3.1 update what are options to change CSC?
For ex. I have SM-N986U unlocked Tmobile device but i changed CSC to ATT as im currently using ATT Prepaid and I'm on latest Apr update for ATT
How can i revert back to Tmobile CSC?
Do i need to flash Tmobile firmware using ODIN by first flashing to U1 firmware then Tmobile firmware or can i directly flash Tmobile latest firmware with Apr update using ODIN?
Will i be able to retain my app and data if I flash Tmobile firmware?
Any help will be appreciated.
Thanks

So you state csc change not possible then ask how to change it? lol.. and if it were as easy to just flash firmware in odin tgen that wouldve been the way to do it to begin with I would think lol

Update:
I was able to change CSC(ATT/ATT/TMB) to TMB/TMB/TMB but it was long and winded way. Just flashing firmware was not enough , need Tmobile sim to install carrier service and change CSC.
I followed the steps below:-
1) Did backup of my device using Smart Switch and removed my ATT sim.
2) Flashed latest T-Mobile firmware( N986USQU2DUC8 ) using instructions from post - https://forum.xda-developers.com/t/ota-and-non-ota-firmware-for-n986u-and-n986u1.4143833/ . Also, downloaded the ODIN (patched version) and T-Mobile firmware from links in the post. Flashed HOME_CSC too.
3) After rebooting phone with new firmware , the boot up screen was still ATT and CSC was still ATT/ATT/TMB.
4)Shut down phone and inserted Tmobile SIM i had lying around.
5) On reboot, i was asked to install Tmobile carrier services and on restart , Tmobile logo came on boot up with CSC changed to TMB/TMB/TMB.
6) Now, i have esim enabled and SIM manager showing up too.

thats the normal process.. that firmware is same for each carrier.. firmware is multi csc which changes based on sim inserted.. shouldnt have to go through all of that really.. i think most ppl who have issues are trying to change csc without a active sim card or on carrier locked devices etc.
glad u figured it out tho!

Well, the confusion for most ppl who are new to Samsung and CSC, like me , is that we could change CSC with code earlier and now cannot. Didn't have these issues with pixel and iPhone.

Yes, I was able to change CSC to ATT from TMobile, enable all LTE/5G bands before One UI update.Not, sure what u find so funny .
Yes, I'm aware that there is no CSC concept in pixel or iPhone or any other other manufacturer that I'm aware nor they are crippled in terms of hardware capability from carrier software like Samsung. LTE/5G bands not being enabled , esim not being enabled etc.

actually other devices are crippled in some cased disabled entirely.. for example u cant get a tmb oneplus 9 pro 5g and use it on verizon to get 5g bcuz vzw 5g bands are disabled in tmb variant..
its really the carriers to be honest..
and I say LOL all the time even in normal convo so not actually laughing sometimes, just say it out of habit

I have phones such as Z Flip3 5G and other models that do not change CSC like older models when following the flash procedure starting with U1, but the phones never prompt a restart. I have noticed it seems to be with TMB or VZW units. Any suggestion on how to actually get the CSC to change properly or is this something they are doing with new phones to avoid being able to use them fully on other carriers?

Go to the page, download theirs Samkey app, buy few credits on Ebay and you can change the CSC as you wish in a minute, the phone will reboot without loosing your data, it's the easiest way as far as I know

Hi, I have yhe following issue and I need your thoughts please.
I have a Telus plan, canadian with US roaming option.
I am traveling in US alot. I have a Note 20 Ultra U1 from Samsung USA. When in US I can only register on Tmobile and I can get 5G icon too. Won't let me on ATT or Verizon.
With same sim card in Note20 Ultra "W" variant, canadian one, it wil register on all 3 major networks in US. No issues with the sim, I guess.
Also in Canada won't get 5G ever.
My provider said nothing to do with them, Samsung told me the same.
I reseted all network setings my APN is ok. VOLTE on. Only getting acces to Tmobile.
Any ideea how I can fix this ? Is it related to CSC ? Mine is XAA.

(HELP)SM-N986U1 change CSC to TMB - Enable ESIm

Hey Everyone,
I have unlocked SM-N986U1 with the latest update installed (Updated with latest June update). I wanted to change my CSC to TMB (T-Mobile) so as to enable ESeim support. I tried using Samkey, wasted 1 credit too. It said CSC updated but nothing happened, my carrier still shows XAA.
Can anyone please guide me on how can I change CSC to TMB?
Thanks.

These links'could help. I think you have to flash the TMB Rom which enables and support the eSim on the phone. It would help to have a Tmobile Sim around during this process but I have heard others say it is not needed.

Yes you can. My device is from Xfinity and I have done the switch to any Carrier I choose on bootloader 2. U1 to U and back is doable. The key is to use the modified Odin as specified in the guide.
"
2. Download Patched Odin here
3. Unpack/Unzip what you downloaded in Step 2 (Odin Compatible ROm) and put in a folder. Lets call the folder "Flash"
4. Run Odin, click on BL, Browse to the "Flash" folder, add BL file from there, Do the same for AP (click on AP, Add AP file, this will take some time), Same for CP (click on CP, Add CP file)
5. Do the same for CSC (click on CSC, Add the file with the name starting with Home_CSC). If you use Home_CSC your phone will not get formatted and data will remain Intact
USERDATA Stays empty.
6. Now connect USB cable to your laptop (Only laptop and not the phone)>> Turn off your phone >> Press volume up and volume down keep them pressed and plug in the USB type C into your phone.
7. You should be in download mode now, press volume up. In Odin you will see that phone is added.
8. Press start in Odin. Wait for it to finish and let the phone restart (it will happen On its own).
9. Done

1) I used frija to download the firmware (I typed CSC: TMB in frija, as its the first time I am using it, is it the right way)
2) I also checked the version in frija with the CSC: XAA, the version is same. How can I make sure that I have downloaded the correct TMB firmware.

So the Model is 986U/DS ? And is eSim enabled ?. That is the state you would want to be in. I understand the last XXX in the service provider software can't be changed. Mine didn't change and stayed CCT which is for xfinity but the as you can see, I have TMB/TMB, TMB/CCT. Esim is enabled and my Mint mobile (Tmobile) number is on it and I have a foreign physical Sim which is roaming on AT&T on the physical slot.
You might be close.

Also picked this nugget up from another thread
"You have to flash full tmb firmware. Not xaa tmb but 986u tmb firmware. The esim is in the user data section you'll flash"
Others have suggested you have to do a factory reset or flash the actual CSC file not the Home CSC which means you will loose DATA. I was doing this on a phone I had not setup yet so didn't mind loosing DATA. I am also assuming you have a TMB sim card in the phone because I understand that is needed so the phone can connect to Tmobile and download the carrier data files that actually changes the CSC after a clean flash.
These are just some of the things I picked up from here when doing my conversion.

Yup I used the TMB version only. The model Number changed to 986U/DS. In About phone, it shows me the IMEI of the Esim, but its greyed out.
The only thing I dont have is the T-Mobile Sim. I think thats whats causing the issue. I will arrange a t-Mobile sim and try it tomorrow.

Since the OP looks like problem solved, and not wanting to waste new thread, i have similar issues, can you help?
I have an S10e I recently broke (amazon renewed w/U1 FW), so I got another S10e from amazon, renewed which appears to also be U1 FW.
Except the latest, the replacement phone, the one I have now, NOONE can hear me, like all the time!!!!!!! Dead spots everywhere! Its so annoying. Its like i have a bad Mic? Or something...
This didn't happen with my identical phone, the one I had prior to this one, using identical sim.
I'm on Mint mobile, which is a TMO MVNO and currently have XAA/XAG FW running on the new S10e, the new one w/bad Mic or FW problem
It appears I am on U1 Unlocked USA firmware on latest phone ( i may have flashed FW Odin when I got this new one-to be safe- i forgot)
ALSO: BOTH renewed S10e's I've Purchased from Amazon, when lookup the IMEI, it shows as the AT&T Model. Which i understand the U/U1 FW can be swapped, BUT, both phones were advertised as U1 Models for the Hardware, so they sold me U models but they flashed with U1 FW probably to make more money. (this may seem trivial, but Samsung specifically has stated TWICE, that I couldn't Beta Test their last to major android FW's, because my phone shows as At&t on their end, and not the truly unlocked U1 model, for which the beta tests were for. And i was told when i purchased it was fully unlocked U1 ver. The phone itself even says its 970u1 in settings etc.)
Are there ANY hardware (including frequency bands) differences between U and U1 Models???
Is it somehow possible that my CSC, or FW on my phone is affecting my phone so badly that people cant hear me like 88% of all calls? Like should i flash different FW, or reflash or use different CSC??
Is it possible that if I went with a locked TMO FW (or another) that I could possibly, maybe get better reception so folks can hear me better? Or hear me more often or more frequently?
How often do mics go bad or get dirty on these? Can a mic be cleaned?

I have been in the other Note 20 flashing thread but I am stuck. Tried so many ways but can't get the TMB csc to stick, always shows only XAA. I have TMO sim card too. Not sure if they blocked it on the newer releases of the phone
Has anyone tried Samkey to do this? Heard it only takes 1 credit but smallest amount of credits to purchase on ebay is 10 and I dont feel like investing more money into this effort
