Downgrade from 5.2 to 3.2 partly successful - Shield Android TV Q&A, Help & Troubleshooting

Today I attempted to downgrade to Marshmallow. First I tried downgrading to 3.3, but that resulted in bootloop. I then tried 3.2 and it worked out all right. I left out the bootloader and flashed all other files included in the factory image. To prevent the forced auto update I used TWRP to move TegraOTA.apk to a folder of my choice (I have also blocked OTAs through my router since one cannot be too careful).
Most things seems to be working. I got a green light when I tried to pair Shield Accessories but managed to connect my remote by the general bluetooth pairing. I also had some trouble getting the Shield to discover my 5G network, but I solved it by changing wifi channel.
Edit: I get a green screen when streaming via Kodi (which isn't a problem if you disable hardware acceleration in Kodi's settings). Also can't get Chrome to detect the Shield when trying to cast. The two only major problem to rectify.

Wireless "Disabled" - help

I just recently got this tablet from someone else. (This person had no problems and is trustworthy in reporting all that was done and care taken with it, even offering on advice on things you can do with it.)
My first step was to connect to Wifi. This happened without problems.
When returning home from work where I also connected, my wireless connection(s) said "Disabled" after trying to obtain the IP where they worked fine before. The first time this happened I had to do a factory reset to solve it (hardware reset didn't do it).
Today, it is happening again. I woke it from "standby" to start using again at home and received this message. In fact, any attempted WiFi connections comes up saying "disabled" after attempting to connect and obtain an IP. Again, these are saved connections that previously worked. I know for a fact that it's not the routers.
Please help if you can. I've tried:
1) power off/up 2x in a row to no avail
2) removing and adding back the connection with the appropriate passwords
3) a factory reset but I really don't want to do that again because I'm afraid flashing it back will bring back the same problem.
3) I haven't put any new apps on it since it last worked earlier today so I can't figure that as an issue. The first time it happened a week ago was when I'd just gotten it. It has worked for almost a week without problem. I did nothing special but travel home.
SPECS:
A500 Wifi
Rooted (was unrooted when it first happened); rooted now using IconiaRoot v1.3
(previously rooted and unrooted with Gingerbreak which would no longer root)
ROM: Honeycomb 3.1 with Virtuous Picasso v.1.1.0
Kernel: 2.6.36.4-UNITY-V5-ge7dee2a-dirty
Thanks in advance.
it's a known problem with this tablet when moving from one access poin to another, introduced with the update to 3.1. you have to reset using the pin hole near the micro USB port. i use a staple.
it may take a few tries. if it never works, there's a specific file you can delete if you're rooted. if you cant do that, you will have to do a device wipe.
There is a known issue of connecting to PEAP/EAP networks, which most work networks are. After connecting successfully, often many times, it will suddenly fail to connect. It also shows the signal from the access point to be very low or non-existent. After this happens, it can also cause problems with other PEAP/EAP access points as well.
If this is what happened to you, here's the fix. Try to connect to the access point giving you problems. While it is stuck on trying to connected, click the access point name and tell the tablet to Forget it. Then enter the same access point information manually and try to reconnect. This fixed my problem, and the fix sticks for a few weeks or so until it comes back.
Interesting, I had this same problem a few weeks ago when I visited my parents house. After a couple reboots it just started magically working again and didn't think anything of it. Their router is whatever the Verizon FiOS people install when you get their service.
Thanks, GeekGuy and Falkner, but.....
I've tried both before, but I went ahead and tried both of your recommendations again (pin reset and connection attempt/forget/add). Neither fixed it.
I would like to try to delete the file that Falkner mentioned, but you didn't specify a name and/or location of it. Can you share that?
I could never find what file to delete, so I've just installed a new ROM (thanks to XDA for info on all the how to stuff).
We'll see if it repeats.
Gone from V.Picasso v.1.1.10 with HC 3.1 to Taboonay 2.1 with HC 3.2.
Thanks for the attempted help!
Just guessing but I would say your problem is solved since no reply from yesterday?
Per my last post, I've switched ROMS. As it happened randomly before, I can only wait to see if it happens again. I will post back if it does.
And....as of tonight it happened again.
Note: Different ROM working since the last post 9-26-11.
ROM Taboonay 2.1
The only thing I can wonder about is if it happens when it tries to connect to a network that is actually down such that it cannot obtain an IP that actually gets internet access. However, it was "disabled" when I brought it up before ever trying to specifically reconnect to a network to realize the ISP wasn't doing their part.
Still....no reboots, or hardware resets have worked. I'm working on an image restore of only the system from the 9.25 install of the ROM rather than a factory data reset. Not sure if that would have been better. Trying to save some of what I've done recently. Gonna have to get used to a weekly backup if this is to continue.
Grrrrr..........restoring a backup turned out to be the last ROM. After reinstalling Taboonay 2.1, I still had all my apps and found the same problem. I'm doing a factory data reset as it's the only thing that fixed it before :-(
The only "oddity" I've experienced has been since last Thursday. The Android Market doesn't even recognize now that I have another device. Have communicated with them; they are investigating and saying they have received reports of this on free downloads giving an "unable to process purchase" message. It updates installed apps, but I cannot download any new ones through market, appbrain -even the appbrain app only and not to the market app. I can download through Amazon, so it's the Market issue. Still, that shouldn't affect this issue.
If you have any constructive feedback, I'd appreciate it!
This was happening to me. I had problems with every rom I tried until the following combo: Taboonay 2.2 with Richard's Villain ROM 3.7 kernel. Every other combo would lead to erratic wifi...now it hasn't happened in 2 days. I don't know why this is happening as many of the roms I tried claim to have the wifi fix integrated. I hope this helps. Just flash the latest Taboonay and then the kernel zip file on too of it. By the way, latest rabbinate is 2.2....NOT THE ONE YOU HAVE NOW.

How I fixed various problems (bluetooth, fingerprint sensor, stock apps, tablet mode)

BTV-DL09 C100, locked, unrooted
I got the tablet a couple of days ago and I've been battling various things and reading lots of guides, I thought this might help others. Tab was on Android 6 with no OTA available, so before I even set it up, I used the Firmware Finder app to upgrade to Android 7 Emui 5 B307 using dload method and dialler
Everything looked good, I set it up and started using it. Then I realised Bluetooth wasn't working, I couldn't change any of the Sounds, and I had a bunch of missing stock apps including Themes, Calendar, Compass, Sound Recorder (and some more)
I went back to Firmware Finder and re-downloaded B307. Then while reading some things online, realised that when it says to put the update.app in 'dload' folder on SD Card, it means internal phone storage not the actual removable SD CARD...so I did that, and installed using 3-button method, buuuuut no change
Back to Firmware Finder this time trying to download B303, but of the many B303 files available all would error except 1, and when it did download it was always corrupt (I always chose Full OTA's) - each time I tried it would take nearly an hour. I tried the Firmware Finder PC program, and after letting it search for a really long time, it only came back with Chinese versions of the firmware. I also found lots of web pages with links to firmware but NONE of them worked, they were all dead links or would redirect to pages that wanted to install malware
Now I started thinking I would just live without Bluetooth or themes
THEN I followed the instructions on this page http://www.stechguide.com/downgrade-mediapad-m3-from-nougat-to-marshmallow/ and downloaded the files to downgrade from Nougat to MM: . This worked, BUT...upon initial setup as soon as I put my wifi password in it started to do an official update to Android 7 and I couldn't stop it because the O/S hadn't properly loaded yet! I wanted the device to start up properly so I could check that the rollback had worked, and check if Bluetooth and the other missing things were working. I risked it and restarted, then the setup started from the beginning and this time I didn't put my wifi password in and was able to complete setup
So now I was on B009, Android 6, and Bluetooth worked...success? NO! The fingerprint sensor wasn't working at all, not for fingerprints and not as a navigation key - I was forced to use the navigation bar (and it's so ugly!)
I set up everything the way I wanted and connected to PC and Hi Suite so I can do a backup, and finally, Hi Suite told me there was an upgrade to B303 available. I let that run - and after many hours of reading and trying and ending up disappointed, I am now on B303 Android 7 Emui 5, and e v e r y t h i n g works!
Bluetooth works
Wifi is fast
Tablet mode works when you select - View mode: small; Font size: normal
Blockada works to block ads
New Pipe is installed to download YT videos
Animation scale in developer options is at 0.5 so everything is snappy
OK Google works
The stereo speakers are AMAZING and loud
...perfect!
Thanks for sharing, everything working. ??
Great !!! Thanx
I have same issue. On nougat now, no keyboard, bluetooth, missing some stock apps. I am on Nougat, locked bootlaoder, US version. I just want to go back to stock, no root, no 5ghz. So I can sell it....

Wifi dropping conection, and bluetooth not working.

Hello, I have unlocked my phone and flash stock rom nougat 7.1 with magisk, twrp and xposed. Three day after this process I try to install this two mods:
I - https://forum.xda-developers.com/apps/magisk/module-fingerprint-mi-5-mi-note-2-t3660179
II - https://forum.xda-developers.com/x-compact/themes/sound-boost-nougat-7-0-t3684917
And My phone start to drop all wifi conections and bluetooth stops working. So I tried to restore 3 backups that I made first of wifi problem beggins, and didnt make diference. So I flash a new stock rom, with other xperia firmware from Xperifirm, and nothing changed. My wifi conection and bluetooth still sucks.
Here's my questions: is possible that this change break up my network board, is this a hardware problem? Can anyone know if there is a way to know if is a software or hardware problem??
Can anyone copy and post here the wifi (data/misc/dhcp) and bluetooth (data/misc/bluetooth) files to see if i can fix it?
In worst situation I will restore drm keys, lock bootloader and go to a Sony Store, thank you guys for any help, I was really enjoying this phone =X

I've noticed this affecting my phone since the update to the 34.3.a.0.252.
Apps wont load content on wifi, auto update of google apps wont work over wifi, etc. (some have even been sitting waiting on auto updates for over a month...)
As soon as I turn wifi off from the tray, apps update, content updates, picture and videos instantly start to upload
i have not installed either of the two packages you list, or magisk, so I don't think they are related to the issue.
Its not an issue with my router set up as it happens on the main router, a repeater, shared connections, hotspots or public wifi. Its down to the phone and most recent update.

It's weird becase a tried 34.1.a... and didnt make out. Idk if some how I made some hardware crash, or drop wifi is just a bug from my rooted phone. Today I tried to install marshmallow stock rom, and stock + twrp and both with wifi issues, in weekend I ll try to restore drm-keys with locked bootloader.
I saw what heppen with explorer es.app, bluetooth and wifi files are missing, and even with a new flash rom or deleting folder they dont fix up files. The strangger part is that in the beggin everything was right, maybe I break up wifi hardware. My last chance will be install Paranoid Android, and if everything is all right, I will copy file for try to force software fix it.
Did you made anything to fix it?

I've just been living with it, though I may downgrade back to the October Rom version if i still have it while i wait for appropriate O versions, kernels with support for turning off encryption etc..
Just to close this post, and help others members I would like to notice that I solved my problem. Actually, it was just a coincidence. While the installation the required processing burned out the network card of the phone. This fact there is no connection with the installed mods or ROMs, nor either with any of the information or hypotheses I gave earlier. The problem occurred because the x compact's battery its attach with SoC, and therefore it is very sensitive to heat, fortunately my cell phone is warranty and I will get a new one. So, take care !

Wifi not turning on (i9505 - Stock rom)

Hi. After trying a couple of custom roms, I wanted to go back to a stock rom via Odin. I actually succeeded. The phone boots, and android setup screen comes. But in the "wifi connection" screen, when I touch the button to turn the wifi on, it just refuses to turn on. It goes back to off position. I have tried several different country's stock roms (4.4.2 only, I haven't tried 5.0) and they all ended up the same. I just can not turn wifi on in stock rom. Wifi works in custom roms that I installed using TWRP.
Any idea why this happens?
By the way, I also tried flashing different modems, but the result is the same. I read that turning off the phone and removing the battery helps, however, in my case, it didn't.
Any help is greatly appreciated.
EDIT: As I have looked into the issue, some people claim that a custom kernel usually solves wifi problems. I haven't tried it yet but I will as soon as I can get my hands on the phone. Also in another post, I have seen a build.prop tweak "ro.securestorage.support=false" which is claimed to have solved the wifi issues. I am writing these to be of help to others that might encounter the same problem. I will update the post after trying these ideas.
EDIT 2: It turns out, when you flash a stock rom, Odin can't actually flash the modem partition. It seems like it does but it actually fails. You have to do it twice.
No Wifi
Hi,
have some trouble with my Galaxy S4 (GT-I9505). Since 2 weeks I'm trying to get wifi working. 2 weeks ago I decided to root the phone (everything complete stock Android 5.0.1). At this moment wifi was working well..
I did:
- Flash TWRP with Odin
- Flash magisk 18.1
--> booted phone..
Everything seemed to work well..expect wifi. It wouldn't turn on. When trying to activate the WiFi button by sliding to the right it stays grey and after 10 sec. the slider goes to the right side again.
What I've done:
Downloaded several stock firmwares from sammobile --> no wifi
Flashed serveral custome rom's (lineage 14.1, 15.1), android 5.0 and 4.4 based --> no wifi
Tried differnt kernels --> no wifi
Flashed different bootloaders and modems--> no wifi.
Tried to delete files in /wifi folder suggested here in forum --> no wifi
Tried to modify buil.prob set the security value to false suggested here in forum --> no wifi
I don't think thats a damage on the hardware. It must be a software issue?
Bluetooth and mobile data are working well. GPS and wifi seem to be broken.
After spedning weeks of flashinng, recovering etc.. I am frustrated and don't know what to do.
Any advices?
My wifi is not being enabled with this rom. Does anyone know how to solve?

Wifi stopped working after flashing back to stock ROM

I have what appears to be a demo device; this one will not do OTA.
So I installed the newer roms but then speech to text, the microphone would not work except only for calling. I downgraded to the stock rom and it was fine.
But I decided to keep trying I was hoping it might be something I did wrong and could upgrade. Still no microphone so I downgraded back to stock again. This time; Wifi completely stopped working. It will not detect any wifi networks. Some goggle searching said that it is possible the modem got messed up. Not sure what to do. I tried flashing again it didn't make any difference.
One thing I noticed though is the first time when downgrading I forgot to turn on USB debugging, but it still allowed me to do it and it went smoothly.
Having no wifi on a smartphone with no apps on it is a bad thing
Well some google search told me if this happens you can flash to the July Oreo update and your stuff will work. I did that and it worked. My ,ic still won't record sound so then I went back to the 7.1.1 and it works fine. Too bad I am stuck with nouget or my mic will not record stound and I cannot do OTA.
Here is the thread I found which was quite helpful.:
https://forum.xda-developers.com/essential-phone/help/wifi-android-p-t3790678
I just used the July Oreo update, the fastboot version.
