[RAZR HD Q&A, Help & Troubleshooting] ponzs:
Hello. I have a XT925 running 4.1.2. The phone was rooted a long time ago. I don't remember if I installed a recovery, nor which recovery (if any) was installed at the time (volume up + power yields a boot mode selection menu; it seems to be the original bootloader).

My carrier released the 4.4.2 OTA just today. When I try to update, the phone reboots and displays an "Update failed" error message. I uninstalled as many apps as AdAway and XPosed that I think could be tampering with the process, but still I can't install the update.

How can I update to KitKat? (If it isn't obvious by now, I don't follow most of the technicalities of this things with Android. I'm fairly knowledgeable about computers, just not Android. I've read a lot of threads here and still can't figure out how to do this!)

Will I be able to re-root the phone afterwards? Will I be able to unlock it?

Thanks!
[RAZR HD Q&A, Help & Troubleshooting] hbenz2008:
unless you have some concerns about warranty, I suggest go ahead and unlock bootlocader via moto website. Then you are free to do as you please, meaning uprade to kk stock, custom rom and root without hassle.
[RAZR HD Q&A, Help & Troubleshooting] ponzs:
Ok, I did it (and lost everything on the phone in the process). The phone said it was unlocked. The phone is now back to stock, clean 4.1.2. But I still can't update. I get the same "update failed" error message.

What should I do?
[RAZR HD Q&A, Help & Troubleshooting] hbenz2008:
Dont panic! haha you will get it done I have no doubt.

First did you factory reset after all was done. Do that and try again

if not, there are other ways , some easier than others but all within your capabilities

[Galaxy Note 4 Q&A, Help & Troubleshooting] gavinfabl:
Put simply, the Note 4 has the worst signal strength of any phone ive ever had. I use 3 UK. Signal is weak inside house especially downstairs. Recently i have had the blackberry passport which was amazing signal wise. I currently have an iphone 6 plus too. The 6 Plus can make calls downstairs just about. The Note 4 has no reception.

In fact i have noticed the signal is weaker wherever i am...

Anybody else notice this. .

I really like the Note 4 but the weak radio is going to give me a problem. Maybe samsung can improve the radio with a firmware?

This is not good. Maybe we should not have asked Samsung to build a phone using metal! I also have the Gear S which is great. But I need the Note 4 to use the Gear S. I also need a phone to make phone calls so this seems like a design issue. Sad.

Here, in downtown Amsterdam I have bad 4G/LTE signal inside my apartment too, but it's even worse with my Galaxy S5. On the other hand 3G is full bars. In the elevator of my apartment building the S5 loses his signal completely (no network) while the Note 4 survives with a very weak signal. But overall both the Note 4 and Galaxy S5 suck at cell reception. You will have to learn to live with it.

Unlocked N910C Useless as a phone

My reception ANYWHERE is crap. I'm using AT&T's network and I have a Galaxy Tab S unlocked that has a phone and that has 3 or 4 bars to the GSNote 4 having maybe 1. I'm wondering if this happened because I rooted with CF Autoroot, as it seemed to appear after that, but I have no idea. I unrooted and flashed the latest firmware (NK5) and I still has the same crappy phone reception problem.

It is not just the qualacam. I have the n910C and it too has a very bad signal. I have tried every baseband to date and they have no effect. It is only the 3G and LTE that are bad. GSM is OK.

I sometime cannot even get the 3G while my iPhone has a full signal. I too noticed it after rooting. I just don't remember it being this bad when I first bought it.
[Galaxy Note 4 Q&A, Help & Troubleshooting] nacos:
The frame metal has nothing to do with reception (see the placement of the main antenna relative to the body on page 8). I cannot comment on other models but I've got the Canadian N910W8 and my signal is EXACTLY the same as my other 2 Galaxy S4's.

In your cases, I believe it's rather a software issue/mismatch (CSC/modem/RILJ, etc), especially If you bought it from a different country/region, you should probably start with the phone's CSC, matching it against your residential location...

Also, try choosing a non LTE network connections under More Networks > Mobile Networks > Network Mode. If the signal improves considerably, you're living in a poor LTE area. As of right now, since VoLTE is not yet widely supported, only your download speeds would be affected by leaving your phone connected to a non LTE network.
[Galaxy Note 4 Q&A, Help & Troubleshooting] sixline:
Same problem with my brother's note 4 bought from UAE. Its an exynos version. Turning LTE off does not improve the signal strength. On the other hand my note 1 (exynos) and lumia 1020 have excellent reception in the same room.
[Galaxy Note 4 Q&A, Help & Troubleshooting] nacos:
OK, you bought the phone from UAE, but where are you located/using the phone? If you're using it in a region/location other than UAE, then you should probably consider installing the modem for the region you're currently living in, and also changing the CSC.

Poor LTE signal due to incorrect band

I got an N910U for use on AT&T in the US. All the phones in my house get full bars since I am on a hill near a lot of cell towers. Except the N910U usually has 0 to 1 bars and only rarely gets LTE. I used LTE discovery app to see that it is almost always on band 2 where the signal is very poor, but very ocassionally switches to band 17 and gets full bars! Then it quickly switches back to band 2 and gets 0 or 1 bars. I tried flashing the other two modems I could find, but it did not change how it acted. I am about to send it back for a refund and get an N910T instead to see if that works better, but it would be much easier to find a solution to why it won't use the strongest signal,

[Galaxy Note 4 Q&A, Help & Troubleshooting] RyJa:
Any solution to this thread?

My Galaxy Note 4 has a issue. When in LTE/WCDMA/GSM mode there is no cellular signal and I am not able to make and receive calls. When I select GSM mode or WCDMA/GSM mode then the phone signal is good and working properly BUT I am only getting the 2G and 3G speeds.

I have done hours of troubleshooting with Samsung Australian support service and also with Amaysim. The sim card is 4G, new and works fine with 4G on my old phone. This issue I am describing occurred with two different sim cards that both function well on other phones.

I have lived in a 4G area for 18 months and have had a fairly consistent 4G service.

I ended up researching and finding some information that I believe may fix the issue.

almost-a-technocrat.blogspot.com.au/2014/12/how-to-force-only-4g-or-lte-network.html

My theory is that because the phone comes from China, it may not have the settings for 'All GTE' but rather it could be set for other countries.

I want to access service mode to check for the GTE Band settings but the code referred to in the website gives a response 'Invalid MMI code' and Samsung Australian support is not able to assist.

I wondered if it can be accessed through Developer options? I don't know how to do any of that.

[Sony Xperia ZL] ninguem98:
I would recommend to you to download some custom rom, extract the boot.img and flash it via fastboot. After this, the recovery mode should work, and you can wipe data, cache and dalvik, then install some rom. After that probably the flashmode and fastboot should work perfectly, and you can install the stock rom, if you want, of course. I'm not responsible for other brick, but i don't think that those steps could brick your phone. I follow this procedure when I brick my phone and it works.

Do not make anymore attempts to flash your phone with a lk3 firmware as you could hard brick your phone. This is a 4.1.1 ROM with a 4.1.1 bootloader. Your phone has at least a 4.3 bootloader which cannot be downgraded.

There is a thread about an Odin-flashable 4.3 file but some people have bricked their phones by following posts in the thread.

My advice: flash Philz Touch recovery for the d2lte, flash a CM10.1, and determine whether you have the 4.4.2 or 4.3 bootloader.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Xabier1121:
How do I find out what bootloader it has or needs? Everything else your saying makes sense. Aside from that. Lol.

[T-Mobile Samsung Galaxy S 4] davidshooki:
Can we have a class action suite against Google, the carriers and/or the phone vendors (Samsung in this case) for taking meaningful SD support away

1. sue to get reimbursed for the cost of the SD card which is now nearly useless.

2. sue them due to conflict of interest where the carrier charges for bandwidth-- when we use cloud storage instead of SD storage and where google is effectively forcing us to use the cloud-- which google has a great interest in.

Even a symbolic attempt at a class action suit maybe useful.

Maybe that will force google to pay attention to the user rather than to their big plans which they force on us?

Searching is so yesterday! I should be able to come and ask any question that pops into my head regardless of how many times it's been answered; I mean.. this IS a support site, right? :D

I'm obviously kidding. I just wanted to chime in.. what's so different about KitKat's SD policy and JellyBean? I mean, other than that SDFix app which I haven't had to use since KitKat first came out, I haven't noticed any difference in accessing the extSdCard between 4.2.2 up to 4.4.4. I assume most custom ROMs have the fix built right in? That could be why I haven't noticed it now that I think of it...
