Converting a X727 to a x720, 4G bands supported ? - LeEco Le Pro3 Guides, News, & Discussion

Hi, I´m from Portugal and my Carrier is MEO. For 4G they support band 20/3/7.
I want to buy LeTV LeEco Le Pro 3 X727 and it says he only supports 4G FDD-LTE: 2/4/5/7/12/17/29/30/38.
LeEco Le Pro 3 X720 support 4G FDD-LTE: B1/2/3/4/5/7/8/20.
IF i install Lineage rom, or another Rom for X720 on x727 model, do he gonna support the same bands as 720? the 2/7/20?
Thx in advance and sorry for my poor English.

This is not right. X727 have band 3 100%...

Yes I confirm it has B3, I checked on the official LeEco website.

Also to answer your question, the supported bands are written to the NVRAM of the phone and aren't part of the rom. So no, if you flash a X720 rom on an X727 you won't unlock any addition bands.

So the supported bands are not written in baseband modem that we flash?? Interesting..

Yeah, the baseband chip support all bands as it's part of the SoC. The modem driver is kind of generic. It reads a bit of read only storage on the phone called NV_RAM which contains stuff like the bands the phone supports, the IMEI, etc. So it is sometimes possible to unlock additional bands by editing the NV_RAM

So editing this in the Build.prop makes all x720 custom roms compatible with x727 (in theory)
*EDIT - Of-topic: Melbourne look likes the best city ever. Moving as soon as possible

I have the LEX 727 from Amazon but no working bands 2 or 4, any ideas to help me? changing the rom to the chinese version? something in the modem, baseband?

NVRAM isn't in the build prop, its a special bit of persistent memory in the phone. To edit it you need to put the phone into diagnostic mode and use QPST.
And yeah, Melbourne is pretty sweet. I hope to see you here soon!

Support for 4G LTE 2600(7)

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.

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...

1002.10E6 ifwi_ann_a0-mofd_v1-DBG.bin

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!

Unlock FDD LTE Band 3 (1800MHZ) on OnePlus 3 US Variant

Is there any way that I can buy the EU\Asia or Chinese variant of OnePlus 3 in US from OnePlus or flash a custom ROM or kernerl to get LTE Band 3 on the US variant?
OnePlus AMA going on over @ Reddit, there is no 32GB model coming.
https://www.reddit.com/r/Android/comments/4o308u/oneplus_ama_oneplus_3dition/
as all three models are sporting the Snapdragon 820 you will most likely find it is a ROM lock to certain bands and so flashing the EU/Asia ROM will open up Band 3, Otherwise CM13.
i am interested in finding this out also?
thank you

It actually might be locked on the Modem side.
Since there were tools to unlock the Bands for OP1, there might some tools coming to do the same for OP3.

P1C72 ROW have all lte bands unlocked?

Hi,
As titled, I would like to know if P1C72 ROW, has all lte bands or which lte bands he has?
A ROW rom will only work on a ROW phone, correct? I mean, if the phone is CN won´t accept or work with a ROW rom, or am I wrong?
Thank you

Many have successfully flashed p1a42 firmware (ROW) over p1c72 (CN) including myself. Others have reported that more LTE bands were then unlocked but I can't vouch for that as my LTE carrier also supports some bands already useable by the CN model, so I won't know for sure

Hi All, I have a China purchased P1c72 and updated it and it went pear shaped, I have managed to load a ROM that operates (P1a42_S152_160126_ROW) but it appears to have messed up my sim settings, none been seen, when I do the #### region code thing, it has no option for UK/Ireland...anyone able to help, maybe help me find a ROM or easyimage.zip to get a fix
Fixed.... Restored the qcn in recovery, have the sim working.

Make sure the devices lte bands match that of your carriers lte bands. Dont look at 2g and 3g bands. Only lte bands. Second id say make sure your apn settings are correct.
And last is make sure in mobile networks you have global or gsm cdma and lte selected
---------- Post added at 11:22 AM ---------- Previous post was at 11:19 AM ----------
A lot of times this could be due to specific hardware not picking up propper lte bands or those bands not being enabled. Which u can google on enabling hidden lte bands. I didnt notice what model u had from the seller. I noticed u said manipulations of unlocking bl so where u sucsessful? Then its a h815 i believe which would be the global model. Which then could be software relTed or a settings issue.
I had not specified that it is a h815 international version but planned for a planned commercialization in Singapore. According to my operator the antenna 4g near my home uses only the band 800 which is normally compatible with ... I also have a lg g4 that works perfectly with my chip. All APN settings are correct .. Is there a way to force to use this tape?
I tried manipulation to unlock the bootloader with the official version of LG but it is an Asian phone .. I thought of a software problem so I tried with lg bridge that does not pick up my phone. Is there any other way?

Unlock BAND 20 LTE

Hello folks, i need your help to unlock the band 20 of redmi K30 5G. Currently i have Chinese rom installed .
Is a way to unlock the band 20 ? I saw new Xiaomi MI 10, if you change the rom will enable the band 20 . ( in that case is a software limitation)
In our case ?
Thank you !

People tried to unlock bands at the poco F1, but, there was no success, And people tried a lot
I found the possible files causing the restrictions on LTE and 5G bands, but I have no idea how to modify them to unlock bands.
In the policyman folder, the files:

These files doesn't unlock B20 - this is hardware limitation. Bands are configured to nvitems but on 5G phones many things changed.
But could you please share to me your modem log file so i can list all hardware supported 4G bands to my cacombos.com website? I have here instruction how to get log file: https://mt-tech.fi/en/how-to-get-4g...phone/#Method_for_Qualcomm_Devices_after_2020 and you can send it to: https://cacombos.com/contribute . This help me understand what bands & combinations this device support.

If you change any ROMs from global to China and vice versa won't unlock the bands. This is locked down with hardware, not software. Older Qualcomm devices could unlock bands with Qualcomm tools/programs. This isn't the case with newer models.
