Hi.
I've purchased a ZE551ml in Taiwan, here in Chile we use 4GLTE 2600(7), the TW version doesn't support that band, I've flashed the latest firmware, and now the version is "LRX21V.WW-ASUS_Z00A-2.13.40.13_20150401-8390_USER044030427_201501060109", this means I'm in the WW firmaware version? If not what can I do, and add support for 4GLTE in 2600(7) band?
Thanks for your help.
It is my understanding you will need to purchase a WW or US version to get band 7 support. The WW version in France should be released soon. No word on the US version.
I am not sure if there are different versions of ZenFone 2 ZE551ML (as for the hardware). I bought the ZE551ML from Taiwan about 2 weeks ago. It came with a WW firmware & I am living in Romania (so Europe). I did had some issues with LTE even after the last OTA update (the network kept dropping again and again). I solved the issues! For me, I only had to change the phone's ATP settings with the ones required by my network operator (Settings -> Wireless & Networks category -> More -> Cellular networks -> Access Point Names). Now I don't have any issue. Maybe you could try to find what settings are required by your network operator.
Thank you for saying this. I also have a TW ZenFone 2 and it came with WW firmware. I thought it was a mistake.

Although it's WW, it's not the same build as real WW model.
I also have Zenfone 2 TW version. Re-flashed it to WW just to make it more generic.

Yeah, true. There is, for example, an asian-market game-store app, pre-installed. Even though my phone came in with a WW firmware, I chose to flash it with the WW ROM from their website (I thought it would have been a more light version with no 3rd-party apps like Kindle, TripAdvisor, etc...but it's the same )
My phone is working with 3G, and network APN are well recognized. Only have problem with 4G. I think the hardware must support all bands, it's a feature of the chipset. So I hope that with a different version of the firmware fue 4G could work.

For me, the APN was recognized, as well...but I had to make some changes in some names. I hope you will get yout problem solved, somehow.

How do you figure out if your Zenfone 2 is TW version if I may ask?

On the box check C.P/N barcode. Last two letters TW means Taiwan version.
Also, Taiwan version when bootы first time, suggests Chinese Traditional language by default.
Change FIrmware???
I keep reading different people saying: "I had CN firmware so I flashed WW firmware ...." while on the Asus site, from where I got the firmwares, says "DO NOT FLASH FIRMWARE OF DIFFERENT SKU VERSIONS" ... it explains further "CN SKU should flash CN firmware".
Can someone lead me in the right direction and tell me how to flash my CN version to WW version? Do I just flash the WW firmware off of Asus's site?
here is the bands it shut support from the differend versions

It seems that installing a different region firmware will work, but the bands won't. However, i know that the ZenFone 2 uses the same LTE modem in all these ZE551ML devices (Intel XMM 7262 Slim Modem—LTE Advanced). But this modem may come in 2 variants (not sure). I contacted Intel and Asus for more info regarding this. I know that there was an issue with Galaxy S5, for example, where some bands weren't allowed by default (market related), even though the phone supported them.
Flashing firmware from different region won't change supported 4G bands. Bands support relies on region of phone, which is defined in SFI (it's simpler version of ACPI found in PC) OEM1 table, and it's not touched by flashing procedure.
Although, it may be possible to spoof HW region in kernel. But it requires unlocked bootloader.
There may be another way to unlock bands: copy one region specific file set to another region set, but it may not work. This method doesn't require unlocked bootloader.
BTW, there is one more region not mentioned above, called FULL. So, according to name, it should support frequencies from all regions.

Taking a look at the recovery last_log file, the latest WW_ZE551ML_2.15.40.10_20150425 firmware include quite a few ifwi Image FW versions:
ifwi: 0002.50E6
ifwi: 0002.00E6
ifwi: 0005.00E6
ifwi: 0088.0163
ifwi: 0094.0171
ifwi: 1002.10E6
IFWI FW Major version numbers (the first four) have to match before it will flash the firmware.
I suspect these may be the different regional modems in our device, but allows ASUS to push a single firmware.

There are exactly 6 ifwi_ files in ifwi.zip inside the ROM package. But I can't figure out their versions... Maybe we can flash an ifwi with different major version with xFSTK Downloader?
EDIT: Finally got something...
0002.00E6 ifwi_ann_a0-mofd_v1.bin
1002.10E6 ifwi_ann_a0-mofd_v1-DBG.bin
0005.00E6 ifwi_ann_a0-mofd_v1-DSDA.bin
0002.50E6 ifwi_ann_a0-mofd_v1-SIL.bin
0088.0163 ifwi_ann_a0-mofd_v1-ze550ml.bin
0094.0171 ifwi_ann_a0-mofd_v1-ze551ml.bin

doing so can we change modem region and available lte bands?

Maybe not. (I'm wondering if -DBG version allows unsigned kernels, like unlocked bootloader, and if phone will recognize it)

I don't hope much. There are 2 different ifwi binaries:
Code:
ifwi_ann_a0-mofd_v1-ze550ml.bin
ifwi_ann_a0-mofd_v1-ze551ml.bin
But only one DBG version.
It means, DBG version is for special DEBUG device, with probably special hardware config, neither ZE550ML nor ZE551ML.
It's possible, that ZE551ML and ZE550ML are the same at bootloader stage where existing differences are not touched. But if there is some initialization or even access of device specific config, then wrong bootloader will eventually brick device.
For some unknown reason ASUS choose not to hardlock write access to boot block. It's only "soft locked". It means, with root access you can enable write access and then using dd, you can re-flash boot block. Btw, boot block (IFWI) is written not as-is. Updater reads some kind of settings/config from existing boot block, then copies it to new boot block and then writes it back to flash.
So, it's extremely dangerous to mess with boot block flashing!
What's the different SKU firmwares? I'm assuming JP is Japan, CN is China?, WW is World Wide version and there's a CUCC, not sure what that one is.
The question is, I have the WW firmware right now can I ONLY upgrade using the WW firmware from Asus site? I ask because WW is still at .97 and there's already been two firmware up (.102) and wondering why Asus is taking their sweet time this round for WW updates.
Isn't there more to the ww firmwares?
There's a way to change SKU version in the all-in-one thread. To change it from WW to CN you need a CN fastboot and recovery image (droidboot.img and recovery.img) instead of WW ones provided in that thread. There are many of these in Chinese forums, or you can just extract it yourself.

Hi!
I have purchased a Zenfone 3 Deluxe ZS570KL (SD820 version) from Italy, unfortunately it has branding by TIM (Italian Telecom) and thus a TIM SKU.
Can someone tell me the steps I must follow to change the software (incl SKU) to WW?
Does the Bootloader Unlock tool work on all SKU versions?
I heard someone found a way to install WW software, but unfortunately they didn't reply to questions on issues others ran into and I don't want to risk bricking the phone.
Thanks in advance
You have to unbrand your phone. The bootloader unlock tool works only with WW SKU, but i'm not sure. Try it
Check this thread: https://forum.xda-developers.com/zenfone-3-deluxe/help/help-flash-stock-7-0nougat-via-stock-t3588591
There is also a thread in an italian forum, "androidworld"
After unbrand, you have to replace the recovery with the WW SKU one and then you wil be able to update with downloadable firmwares on the asus website

Hi there,
I would like to flash realme Stock Rom On my realme c21 phone. On the web "oppostockrom.com" there Are many different versions/files
Example :
Realme_c21_rmx3201_PU_11_A.23_210210_rft.zip
Or
Realme_c21_rmx3201_PU_11_A.29_210419_rft.zip
...
Oppo Stock ROM
Find Oppo and Realme Stock ROM (Firmware) for various Oppo/Realme Devices. All the Oppo/Realme Firmwares listed are available for free.
oppostockrom.com
I dont know how do they differ - I dont known what do thé numbers And letters mean. So i dont know which one to choose.
Can anybody Tell me what Is thé difference; or better: give me advice how to get known which version do i Need for my phone
Thanks
Yes, it's confusing. I can only tell you the number after the A is a build number. https://realmefirmware.com/realme-c21-firmware/ has some versions broken down by region.
Any it the android 10 stock ROMs will work an you change your region firmware as as stated before. Android 10;firmwares start with a.xx.xx
The android 11 firmwares are more specific to region from android 10, and hence you will need to download the correct update from website or pick a region and wait for ota update.
Android 11 firmwares are c.xx builds
Here I am again
Finally I have found compatibile stock ROM file. BUT there is still little difference in the file name: the letters in the end of the codename are different:
Built number of my phone:
RMX3201VF_11_C.11
The chosen stock ROM name is:
RMX3201GDPR_11_C.11
What does there letters mean? Is this diference problem? In the web www.realmefirmware.comhttps://realmefirmware.com/realme-c21-firmware/ there is no file with "VF" in the name.
Thanks

I think you'll find the version with GDPR is the name is the European version. GDPR most likely stands for the EU General Data Protection Regulation
It's possible the version with VF in the name is a version specific to Vodafone. Is yours a Vodafone branded phone? As realmefirmware.com is a 3rd party site it does not have firmware links for every region.

Hm. It's strange, my phone isn't branded and never have been. But I am in EU and my phone was bought here, so I will probably use the "GDPR" version.

It's up to you. The safest strategy would probably be to return the phone to Android 10 and let the phone update itself to Android 11 based on its own location setting. Assuming that's how that update works.
Ok. I will think about your method. As you said I Could use any A.xx (android 10) version

Hey guys, sorry for late reply.
Gdpr is global.
A.53, a.23, a37 etc is androids 10 realme ui1 global varient use region changer to change which region
Global gdrp c_03, c_ 09,c_11 is android 11 realme ui1 global
Export, ex c_03,c_09c_011 is non global and generally has a region attached to it

There is 2 EU versions EUEX AND EU brande
Euex is your no branded EU varient otherwise there is the EU branded varients which are generally your Vodafone brands etc which are labelled generally like any other regions firmware.
Under android 10 region selector is the best screen to see this on. Otherwise there is a few files on /system (just have to find them againyself) that have the different firmware regions) can't cahnge it this way but just a good list.
