[Galaxy S6 Q&A, Help & Troubleshooting] JaimeZX:
I have the SGS4 and the "Sim Card Removed" error is driving me bonkers. The SGS4 forum tracked it down to a certain serial number range; but I understand a subset of the SGS5 may also suffer from this. Also posting the same question in the SGS5 Q&A forum...

I'm looking at phones on Swappa; hoping for an idea of things to avoid, if possible, if I go with the S6.

Thanks!
[Galaxy S6 Q&A, Help & Troubleshooting] sofir786:
From my personal usage, I have no major issues with it. Build quality is great and it has future software updates planned too. Camera is one of the best still out there even with the s7, lg g5 and htc m10 being released. The only thing I would say is that battery life could be a little better, for my own usage it's okay I get just about a days use out of it. But if you're on Facebook all the time and playing games then the battery will need charging before the day is up, I always carry a power bank with me anyway so that's not much of an issue. The other thing if you wasn't aware of is that it does not have a microsd slot, so go for the 64gb version I would say. But all in all I've had the device since last September and I'm happy with it till my contract is up.

Quick question, did any of you on XT-1640 manage to safely root your phone?

You know, without losing wi-fi, data etc.? Which method did you use.
[Moto G4 Plus Questions & Answers] Edu_8914:
I did, got no problems so far. But you will lose all data when unlocking the bootloader, if its already unlocked then rooting isn't going to wipe your data. I also installed xposed and got no problems with it

Moto g4 Plus stuck at bootloader

Hi,

My Moto G4 plus is now stuck at bootloader. Below are the details of errors that I get

Recovery Mode - Failed to validate recovery image

Start the phone - Failed to validate boot image

Flash stock ROM via ADB - Pre flash validation failed

Flash stock boot.img - Image boot failed validation (Security version Downgare)

I am not even able to unlock the bootloader as the adb returns a message saying I need to toggle 'Allow OEM Unlock" in the Developers Menu. I connot do that as I cannot boot my phone.

Please help.
[Moto G4 Plus Questions & Answers] Priezti:
Looks like your trying to downgrade firmware there and from what I'm aware you can't downgrade certain sections like bootloader etc. What is it you're trying to achieve?
[Moto G4 Plus Questions & Answers] Karumbaiah:
I was just trying to flash the stock rom. Had some glitches in my phone. While I was trying to flash via adb, couple of steps failed and then I was not able to boot my phone back.

Im sure that I'm using the latest version of ROM. However, it's the one before the latest security patch. However, the boot image and recovery image should remain the same.

Here's the version that I'm trying to flash.

XT1641-XT1643_6.0.1_MPJ24.139-13.1_cid50_subsidy-DEFAULT_CFC

No matter what I do now, I just cannot get my phone to boot in recovery mode or just boot normally.

[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] zakariachelsea:
As you know, xiaomi has released a new version of redmi note 3 pro for taiwan market, and it support the 4g band 20 ( 800mhz ), i got the idea to flash only modem, and test if i can get the band. And it's work !

I'm on MIUI V8 6.6.30 EU ( android 5.1.1 ) and i get the modem file from miui_HMNote3GlobalPro_V7.3.9.0 the special edition ported by AndersonAragao :

http://en.miui.com/thread-300096-1-1.html

But i guess that will work with original special edition modem.

HOW TO INSTALL :

Download ROM

Extract it and get NON-HLOS.bin file from firmware-update folder

Flash it with fastboot ( unlock bootloader requirt ) : fastboot flash modem NON-HLOS.bin, and Voila !

EDIT

I'm not 100% sure that the trick work ! So test it if you want (can) and leave a feedback.

obviously we can lose Calling after flashing modem, so thanks MadVegetable for his feedback

Solution :

get Root,then go to /system fix "build.prop" as this:

change

to

That test not see effective. A more effective test would disable all frequencies with QXDM and activate only the frequency 800, so the only frencuencia for 4g will be 800.

Actually 7.3.9 ROM has 7.3.5 modem file. AndersonArageo ported the rom but it did not start when modem.img is in the zip file. That means you flashed 7.3.5(Android 5.1.1) img file on 6.6.30 and it works thats all. Last 2 photos places are different, just check the map carefully.

[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] SirNoish:
Zakariachelsea here I put the test that you are not at 800 mhz.

I'm not French but I searched a page that displays information for each mobile station.

In the first image you see the two towers that you show in your screenshots

Here one of the towers with frequency information.

I tested the modem now in my phone, i can see the 4g when i put the signal search in manual mode and i can select it, but during the speed test, the internet connection is slow. Also, i can't see the 4g icon in the signal bar. With the original modem, i can't see 4g, because in my city there is only 800mhz for TIM
[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] reggiexp:
that is FREE the operator :)

it doesnt have any 800mhz 4g towers. only 1800 and 2600

but the picture for our friend are from bouygue telecom who uses 800mhz 4g.

https://www.antennesmobiles.fr/ look here you can check the 4 french operators :) free, orange, sfr(vodafone) and bouygue telecom.

bouygue telecom where he lives

LTE 791 à 801 MHz

LTE 832 à 842 MHz

LTE 1765 à 1785 MHz

LTE 1860 à 1880 MHz

LTE 2535 à 2550 MHz

LTE 2655 à 2670 MHz

more i dont know how this towers works but voila :) i think 800 is for long range 2600 for close? if i remember
[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] xtribas:
so is it safe to flash this? i dont want to mess the phone
[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] reggiexp:
now i understand what i means :)

he could only see the 4g tower near his house on 1800 or 2600mhz (close range 4g)

but now he can see the other tower who is farder away from his house so on 800mhz (long range frequency) okay :) good good !) will need to try that tommorow :) (dont want to brick the phone also need some more info, it's my daily phone)
[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] SirNoish:
True, my fault sorry, I was looking the other operator. xD

Well then now confirming that the operator has 800 mhz, the only thing for sure is to disable the rest of frencuencias with QXDM.
[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] reggiexp:

[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] MadVegetable:
I'm on the same ROM as zakariachelsea (xiaomi.eu, MIUI 8 6.6.30, Android 5.1.1) and while mobile data and SMS worked fine with this modem, calls didn't. I could make and receive calls, but I couldn't hear any sound and the people on the other side couldn't hear me. I didn't get to test whether it successfully unlocked any 4G bands.

EDIT: Calling works using the tweak here: http://xdaforums.com/redmi-note-3/how-to/miui-8-6-6-236-0-1-redmi-note-3-t3404890

From what I gather Fluence is Qualcomm's noise cancellation technology... I'll have to confirm whether this firmware actually does unlock the additional LTE bands, otherwise it's not worth giving that up.

[Xiaomi Redmi Note 3 [Snapdragon] ROMs, Kernels, Re] MadVegetable:
I don't know for sure, but I would guess that it does work. It's from a MIUI 7 ROM based on Android 6.0, and if it works (mostly) fine on my MIUI 8/Android 5.1 ROM I think it'd be OK for 7.3.7 (which is MIUI 7/Android 5.1). That said, I have no solid evidence to base this on - just an educated guess.

Sure that you have a kenzo, not a Kate?

Could you please verify with that app on which Band you are?

https://play.google.com/store/apps/details?id=com.qtrun.QuickTest

It needs root. Wind Italy uses the 800mhz and 2600mhz band. So either you are on the 2600mhz band or the 800mhz band, which would be awesome.

Also how did you flashed the Rom? Can't get it working with fastboot/edl/twrp.
