[Q] WiFi Interface Debugging Required - Galaxy Note 3 Q&A, Help & Troubleshooting

Hi everybody,
I have SM-N900 and immediately after buying I noticed the GSM antenna power varies very much and drops calls every minute but WiFi worked great.
I flashed to latest ROM (Android 5 Official) and had most of the GSM issues over and now calls are not dropped.
HOWEVER,
WiFi does not turn on!
It keeps dark green (seems trying to bring the interface up and gives up after a while)
I'm sure there is no problem with the hardware because it was working on the later ROM.
I tried:
- Installing 4.4.2 ROMs again
- Factory rest
- Wipe cache from recovery
- Install many modems (from official releases)
- Those magic solutions like connecting charger when battery id out, etc.
Since no use, I'd like to know whether the underlying Linux OS of my android recognizes the WiFi adapter or not. Therefore, I'm working for a debugging tool that I can see what the error with WiFi is!
Could anybody help please?

Maybe I'd better ask the dear administrator to move this topic to development thread because it seems there is no interest in deep debugging here

[Q] Help! ATT S4 SGH I337 KitKat 4.4.2 : Unlocked and No Wifi - Bad Blue tooth

Hello the Xda developper community,
I have probably tried something with my phone way beyond my abilities (Unlocking my phone!!). My wifi is stuck and my bluetooth not working well. I have tried to fix the problem myself, without any success so far. I am tired of trying and getting I hope you could help me. :fingers-crossed:
See below the description of my problem. if you need more information, let me know.
Thanks for trying,
Kierskia
1- bought a AT&T Samsung S4 SGH-I337, OS Kit Kat 4.4.2 in May 2014
2- unlock it successfully and it worked well for a while.
3- Then the Wifi stopped working (Turn on button is "stuck" with a greyish green color!) and the bluetooth has since not worked well (short silent every 20 sec or so)
4- Just realized today that my phone doesn't show the IMEI number anymore... I read this is BAD. but apart from the wifi and bluetooth, the phone works just fine.
4- Reset the goddamn phone several time using the Kies software (samsung). Each time after rebooting, the wifi worked again for a while; but it systematically stopped working after few days (up to 1 week ).
5- I have tried:
- update/reinstallation software using Kies software: fail
- Root it: can't find the proper software to do it that is supported by my phone
- Use cyanogenmod: my device isn't supported.
- Use At&t website to update the software. not working
- getting my IMEI back: the process gets hairy.

I really appreciate what you guys do.

You can try flashing stock NB1. The unlock is permanent.

Wifi and bluetooth malfunction

I have a p8 lite. A couple of days ago it froze and i had to press the power button for a few seconds to reboot it. After that the wifi and bluetooth are not turning on. It was working fone before that. It just locked tge bootloader and rooted it after this. Do you guys think i can try flashing another rom on it to see if its a software issue. Can i get the baseband or radio for it so i can flash that?
Formwaee is b130

Your help is appreciated.
I am also having the same issue. The phone shutdown and when i turned it back on the wifi/bluetooth stopped working. Wifi can be switched on scans for available network but cannot see any, though my other devices are connected to the same router. There is another P8 Lite phone connected. Router has been rebooted and reset. Same thing happens to BT it wont see other BT enabled devices and other phones cant see the device. I have already rebooted the phone, checked wifi settings, Wipe Cache Partition several times and even did a Factory Reset but it didn't seem to help.

Boot into recovery (while turnig on your phone hold power + vol- + vol+), and wipe cache. It solved for me.

Yes, there is a fix available for the »»» Huawei P8 Lite ««« :
I have the same problem with the WIFI & BLUETOOTH: Both wifi & bluetooth buttons are gray and disabled.
This issue happened after an update from » Android 5.0 | EMUI 3.x « to » Android 6.0 | EMUI 4.0 « .
I researched a lot on the internet and found one useful information:
It is not a software issue - it is a hardware issue.
The best way to fix this ridiculous bug is simply to look for » Huawei Customer Service « so they can change/repair (or anything else they do) your hardware.
This is what i am gonna do the next days.
I hope this information was helpful somehow!

Hi, for me it solved with disabling only bluetooth search. :good:
I have my P8 Lite (2015) updated with original B634, only with bootloade unlocked.
The mobile phone is guaranteed by Huawei until 22/10/2019 (marketing bid in October 2017).
However, in recent days, I'm having difficulties in the speed of wifi (does not exceed 10k / s) when I have the bluetooth activated (for example when I arrive at my house and came with mobile phone connected to the bluetooth of the car).
If I turn off the bluetooth the speed of the wifi normalizes immediately!
Is it a software problem and a reset resolves or will it be a hardware problem to be solved under warranty?
Thank you for your opinion.
its hardware issue,just applied from my mobile operater,in Serbia
this issure is still on update? or they already fix the bug
SOLUTION!
In a Spanish forum I saw that they had solved this problem by installing the ALE-L21C432B564!
I tried but it did not work for me!
Then I remembered to do something I had not done yet!
I reset the factory settings with deletion of internal storage data, installed the rom ALE-L21C432B574 by fastboot (look for link FlashRom B574 Dual Sim).
Surprise!!!
Wifi worked at full speed, even with bluetooth on!
Then I installed the ALE-L21C432B636 by the native mode (dload - UPDATE.APP - off - start with the 3 buttons pressed)...
It is updated and with the problem of wifi + BT resolved.
NEW SOLUTION!
I found the reason for the Wi-Fi problem too slow (or stopping) when Bluetooth is turned on!
The problem is "Your location" from Google Play Services!!!
Until version 11.6.73 (14-09-2017) there is no problem, but from that version, more precisely 11.7.41 (05-10-2017), until today (12.8.74), and in the next versions (13.2 .77 beta), the problem persists.
Will Google solve the problem?
I do not know.
But to solve the problem I found this solution:
Disable GPS-Then go to Settings-Apps-Google Play services-Permissions-Your Location-Location Settings-Disable Access to my location.
From there, you may already have Bluetooth enabled and Wi-Fi will work properly.
However, if you also activate GPS (wf + bt + gps), the Wi-Fi will be very slow again, until you deactivate the GPS again.
It seems that some equipment does not have this problem! If so, good for them, but for those who have this problem, the real reason is already found, and until they solve it (if they solve), we have this solution.
I'm grateful that you also report this error to Google, to see if they fix it.

Successful Recovery Note7 from last Samsung "Death Update" Disabled Battery Charging!

Successful Recovery Note7 from last Samsung "Death Update" Disabled Battery Charging!
Ok, so here it goes, Im getting one more piece of Note7, addictive, I know... this piece has latest samsung's "Death Update" installed, thus its reportedly only working while plugged in with usb cable or charger but otherwise does not charge battery anywhere beyond 0%... so thats that.
My goal is to root this unit, and install custom rom (like hydra rom) and after probably reflash with ODIN with earlier version that did not have battery charging @ 0% cap , then again root the phone, install root package blocking program and just run stock rooted rom with updates disabled, thus having battery charging feature enabled. Ultimately my options of course are to attempt retrofit another battery to it like one discussed here in this thread:
https://forum.xda-developers.com/note-7/themes/note7-battery-swap-mod-note5-s6-s7e-t3545371
, since the model Im receiving has no warranty and it is already refunded unit to the original owner but was "written off" by samsung or whatever you call it, I dont care as long as I get it, I know me trading it in for S7e even aint an option so its going to be my test-unit for DIY and such.
Im wondering would charging features still be disabled if phone was powered via Download / Recovery modes? Anybody had first hand experience? Otherwise, is there anything else in place after the latest death update that prevents phone from being rooted and alternatively flashed with custom recovery/rom to enable charging?
Mega curious...
Hope ya'll having great weekend people

Not sure why you think that retrofitting a battery would allow the device to charge. The update on your device is what is preventing the charge cycle and also is stopping the device from using any radios.
You need to try to flash via Odin a complete rom, probably the last version that had the battery limited.
If you can manage this then you should be disable oem unlock under developer options and then install hydra by following the detailed instructions.

Battery retrofitting mod is not to get battery charging - is to keep note7 fail-proof, and with this specific unit that Im talking about it is especially the case only after getting it back to firmware that did not have it bricked.
I know about "OEM unlock" feature in dev mode is a must before any software tampering, so thats not an issue. I am aware phone works while on cable, so I should be able to navigate and activate OEM Unlock from dev menu, also I should be able to do straight ODIN flash with firmware that is of an earlier version without any battery cap's , so my question still remains - is there anything in this latest deadly update from samsung that prevents ODIN from flashing anything to the phone, or is it just charging orientated?
we shall all see once it comes across, should be following week, Im actually eager to start working with it. May as well just go ahead and order myself a S7 battery too so less time to waste waiting
I have a Note 7 that's on the "Death update".
1) Phone cannot be charge in normal mode or download mode.
2) I did not check on whether it could still function with a cable plug in.
3) Attempting to flash older Samsung firmware from ODIN will not work. It will give some errors and stop there.
4) Could not flash anything through ODIN. BL, CSC, CP, AP could not be flash into the phone.
5) Could not flash recovery from ODIN either.
6) Enabling OEM unlock doesn't help in anything. See point 3 and 4 above.
Hope the above helps.

Vey well, I have some extra ideas too, we shall see
Besides, what are your current plans for your note7?
are you willing to sell it by any chance?

I'm hoping to revive the Note 7 and use it if this is possible at all.
Won't mind selling if there are no other option.
Ok, so got my disabled charging note7, it has about 24% battery remaining and it stays this way if I keep it plugged in on USB or on wireless charger.
I tried flashing TWRP both versions available, both had flashed OK with ODIN however, it still has standard recovery...? wtf...
I remember my S7edge did have very similar behavior, odin would flash TWRP just perfectly fine but when going in to recovery on the phone it still starts in standard recovery, and this would continue until I flashed CF-Autoroot IMG.TAR file , but this time I cannot find it anywhere for note7....
Im thinking trying KingoRoot or OneClickRoot tools but I wanna hold back a little before I launch on those.
Ok good news (so far) , flashed custom kernel via ODIN, worked, but now I figured phone takes charge again while phone is off just on USB, so charge disable mode is within latest kernel update only.
I can still enter my standard recovery and do all I want there (havent tried factory reset yet!)
When powered off from recovery, phone began charging! now I have noticed it went from 23% to 24% and it is showing it is charging, where as before it would vibrate for second when plugged in and then show battery symbol which soon after would go offline and phone would be unresponsive like it is not plugged in - in not charging state. So for now 1:0 me vs note7
EDIT!
YESSS! IT IS CHARGING! NOW @ 26%!!!
Now @ 30% ... ok I should let it charge to 50% and then try perform more firmware DIY
ok, I will confess, I could not wait any longer, thought screw this sh*t, went in to recovery and wiped cache/factory reset, rebooted phone, then witness phone startup OK, welcome wizard started OK with 30% on battery and indicator on shows On-charge thought "yess!!!" , then I get this notification about battery is gonna run out and no longer recharge blah blah blah, but hey , it still charges and now Im at 33%
Yes, latest firmware and custom kernel and VIOLA , note7 is back in the game!
Also got this notification from device security thing asking me to reboot phone to try undo the changes... I guess I will not try just yet out of curiosity will try again to do TWRP reflash, this time it should work
Confirmed, now TWRP flash via ODIN worked liek a charm, so I should root via TWRP now and see if I can disable something in current latest software to disable these notifications playing around now
ok now rooted and lots knox stuff disabled with package disabler and etc, still getting this one notification about discharging battery warning when plugged in, anyone could advice me which file to edit in system root to bypass this?
Thanks
Wow, that's great. I've been trying for weeks but unable to get through to anything. Will it be possible to share on how you get to flash TWRP successfully? Thanks

I'm don't know about the editing stuff but if you could get TWRP to work, wouldn't it be simpler to flash custom ROM that already have KNOX etc disabled?
I was disabling all kind of random packages just to see what results will I get from doing it all , was expecting to somehow find package that relates to USB/wireless pad power circuit monitoring so I could work on it while maintaining the latest patched firmware but no nagging popups every time phone is powered on or plugged in to USB/wireles pad. Otherwise I observe phone is 99.99% perfect aside from the notification that I have described and security centre prompts warning time to time that device has been modified , click restart to undo-modification, which I actually tried and it undone-nothing, so it is permanently patched this way regardless what you try to do within the phone now.
I am in favor of keeping stock rom and stock appearance of note7 as much as possible.... dont know if it makes much sense but I love the way note7 is... with all functions working as much as possible as close to standard as much as possible, so thats why my reasoning trying to make this latest rom work.
I have few firmwares which were the original ones V.1 and V.2 but not V.3, which is what I have, so even if I install custom rom now, there is no way going back to factory firmware since V.3 full factory rom is nowhere to be found.
I am going to look in to ways on how to extract entire current firmware so I can go and learn a bit and maybe do few ROM builds myself, this is actually exciting now once I got this far.
Able to link me to the custom Kernel that you use?

Thanks. It works!!!. Thank you so much.
I managed to flash TWRP and Hydra ROM onto it. Everything works except mobile network. Somehow it is unable to detect the SIM card.
Will fiddle with it further. Hopefully I could get it up and running.
Thanks again.
only downside I see so far with current latest kill firmware and this patched kernel are those nagging notifications regardless battery charging to 100% ok, security center notification about modifications and about restart with attempt undoing them, which obviously will fail anyway anytime, and just now noticed it takes a little more time to activate wifi to show available networks, usually its instant, like 0.1second, and now its like 3-5 second delay once switch is toggled to ON position. Also, found out that when network sim card inserted, now phone prompts for network customization and asks to restart now or later to apply settings changes, and I tried restarting but this keeps coming on anyway, so finding the service package and disabling it solves this issue.
Besides no any network issues here, signal comes on every time I change sim cards around and all connectivity is there with data and all is OK, maybe try different kernel? I tried one with APO ,mine is European exynos SM-N930F model
I tried out Hydra kernel but it didn't work. Then I found this https://forum.xda-developers.com/note-7/how-to/spacex7-rom-kernel-kill-galaxy-note7-t3536693. I flash it and my SIM card works again.
This may help someone
Hi.
As I've read that there are people in the forum with problems after the last update from samsung, I decided to write my experience.
My first Note 7 was the Hong Kong version. It was amazing, because it had an fm radio built in, but of corse I couldn't flsh a costum rom on it, as there as none in the forum. In time, a gave up and send it to samsung, and I am glad for, since by now, I would have a death phone.
Anyway, after 2 months with a s7 edge, I found a person selling is international note 7, cause he would go to Brasil, and was afraid to had it apprehended at the aeroport. So I bought it, even with the limited charge at 60% problem.
First, I tried the Dr. Keatan rom, but the limited battery charge still persisted.
So I tried the TEKXodus rom, and I say its amazing.
My phone now as the batery charging to 100%, and even the shealth works fine, if you don't update it.
If it as an automatic update by google, just downgrad it and is fine.
When I received the samsung notification for the last update, I just needed to be sure that the update function was turn off, that the processes in the background were off too, and, with titanium backup, to freeze 2 "urgent update" apks.
Everything works fine.
So, for those who have problems, I recommend the TEKXodus rom.
Best regards

WIFI problems

Hi,
I open this thread because I detected this issue after doing a downgrade of the STOCK ROM.
- After apply the OTA for NPNS25-137-33-11 (RETEU) and return to NPNS25-137-33-5 I start to see very annoying troubles. Sometimes, when the WIFI state changes (mainly when stating it, or enable hotspot mode, or chaging from one to other network) in this case the phone hangs. The only solution is a hard power-off. Also I noticed that the WIFI range is very small.
I listen before that some users have troubles with WIFI. I haven't detected any problem before, only now. My assumption is that the OTA has updated some partition with RADIO data. Then, now the driver is unstable.
Perhaps some others have a similar problem because an upgrade using a flash backup and not upgrading their RADIO partitions.
Please, share your experiences to see if the problem is widespread?
Thank you!

SM-N910F to daily usage best roms and suggestion.

Hi friends. Yesterday my main phone (a OnePlus One) as decided to pass away
The lower part of touchscreen it's begin unresponsive and the phone it's pratically unusable.
My brother today gave me his old "Galaxy Note 4". he uses it at home with wifi whitout sim and it's usage to play some little games (his main phone it's a Note 10+) etc etc.
To replace my actual OPO i thinks it's a good temporary phone this Note 4........he asked me if maybe I could update it especially because the phone has the actually last official samsung image based on android 6.0.1.
we gave a view to several guides today but I got a lot of confusion...... who can show me how to behave ?
The phone it's completely stock.... it's never rooted or somethings similar mod..... has always and only installed the official updates that samsung distributed.
Every suggestion it's been accepted....... thanks in advance.
For absurd I have read that it is a N910F from the battery compartment and from the system info...... how i can check correctly the exact model of phone for prevent brick or somethings similar issue ?
*EDIT*
If from "phone" i tap *#1234# it's appear:
AP : N910FXXU1DRI2
CP : N910FXXS1DQA1
CSC : N910FFITV1DRJ1
It's be usefull this value ?

Sorry to hear about your OPO.
Yes, you can use the Galaxy Note 4 but of course depends on what you wan to use it for and what kind of phone user are you?
The SM-N910F shows it is a European model, so probably won't work in the us. However it does have a Qualcomm porcessor so should be able to run any ROM you decide to install as long as you get the Snapdragon version (NOT Exynos)!!!
Honestly, if you are just a casual user, you can certainly just leave it as stock and just keep everything as it is. I should caution you that messing with operating systems, or rooting, or firmware could result in your phone not working right anymore. And since this is your only working phone now, you need to consider the pro's and con's.
However, if you have a laptop or desktop computer, you CAN download some software called ODIN and it is fairly easy to flash new A)Firmware - how your phone handles radio signals B)ROM- how your phones operating systems work and C)Recovery - on board software that helps your load ROM's onto your phone.
After some time it's pass i have right now successfully installed TWRP on my phone using odin.
After that it's almost easy to flash roms or zip file for made obtain root accees or all other things.
Whit my old OPO these were things I had been doing for years.....
I just had to find the right directions to start all...........
I am in the same situation as you.
I have an old Note 4 SM-N910F. The phone is on latest stock firmware, but is hell of a slugish. Everything is sooo slow. SO i decided to flash some custom ROM.
I just want a phone that runs smoothly and everything works (fingerprint, camera, wifi, BT). No need for dozens of customization etc. I don´t care about the OS version.
Tried so far:
Dirty unicorn (android 6) - no wifi, camera FC
Resurrection Remix (ANdroid 9) - camera FC
Now I am on a crDroid 4.7.2 (android 8) - camera FC, reboot ends with "device unable to boot normally)
I do always a clean flash. Maybe my phone is broken.

Try crDroid 6. No problems with my camera....
@Unidave199 i have installed lineage os 17.1.
I obtain no sim signal sometimes at reboot of my phone.
I hope it's not a HARDWARE fault.........

No, its more like a a software thing... It happens to me occasinally as well.. I just reboot until it connects.
Hi
any other suggestions for stable ROMs ?
Lineageos 18 is great (freat work from Ripee) but has a 5 min GPS lock and bugs with Bluetooth which is an issue for me for work.
