LG G3 d855 problems after flash

Hello. I have d855 android 5.0 . Wanted to install cm 13. and here are my steps:
1. Rooted my 5.0 , flashed TWRP, and flashed CM13 and gapps. There was a problems with dialer after flash, so i downgraded phone into 4.4.2 V10a (using .tot and .dll files) . .
2. Again tried to flash CM13, but process was aborted and phone bricked.
3. Flashed stock 4.4.2 again. Again no luck to write CM .
4. Flashed stock 5.0 v21a using lg flashtool. Again - if i want to flash CM - phone always bricked (error executing updater binary) . And now, even with stock 5.0 my phone data connection do not work (only wifi works)
Please help .... how to reflash my phone and get CM and back data connection??

Just tried flash 4.4.2 again. Flashed successfully, but still any data connection Tried update into 5.0 using phone software updater, but after few updaters it fails (invalid software package).

Today found, that data connection works perfectly if i set GSM/WCDMA . If LTE is selected, there are no data connection at all. Also, can't flash custom rom, phone always stuck at LG logo. Anybody can help so solve my problems?

I want to cite only the first point you described, because it's "abominable"!
Sorry for the harsh tones, but... the dialer issues obviously involved the Cyanogen rom, especially because you're using the first nightlies, often unstable.
Why you accused the official firmware (therefore no more existing since you replaced them) and decided to downgrade?
Then you've to known that important downgrades like Lollilop > KitKat may irreversibly corrupt system partitions like "efs", which make your device losing of IMEI code and mobile data!
Now the only thing you can do is updating your device by settings menu until you reach latest firmware (21A).
Since you've to manually confirm each updates (10A, 10E, 20A etc.), the process will take almost 1-2 hour.
When the update process in definitely completed, you can try to root device, install TWRP and flash latest CM13 nightly.
In case of other issues, try the quite stable CM 12.1, or the stock-based FulmicsRom.
If you continue to have troubles, do a CSE flash of 21A firmware and send your device to warranty.

Last time I connected my phone to LG mobile support, and it automaticallly updated my phone into newest official 21A firmware. IMEI - OK, data connection - still do not work when LTE is selected. So what i need to do now ? Try to root, install TWRP and flash CM 12.1 or FulmicsRom ?

So what's your problem when LTE is enabled?
Mobile data won't work or simply fallback to HDSPA?

Surely downgrading the entire firmware to the first release of KitKat broke the radio part of your device.
Probably if you downgraded to latest KitKat firmware (10h maybe, instead of 10a), LTE should works properly.
Have you encountered that connectivity issue even before flashing CM 13 (on official firmware)?

No, after flashing everything was fine. There is a way to reflash radio part without downgrading again ? Because when i spoted that data connection do not working, i downgraded firstly to 10a (no data connection), then i get 10h update - still no data connection. And after 10h update, my phone got another update, but showed that can't update because package is wrong of something. After that i flashed 21A what i have in my phone now.

Probably the mobile data issue was related to CM 13.
But when you downgraded to 10A, the radio part was really damaged.
As I said if you want to downgrade, always preger the "less old" firmware you need.
Like you, I downgraded in past to KitKat, but I never looked for 10A! I directly flashed 10H.
Sorry, but at this point I don't know what you have to do.
When you flashed 21A firmware, have you done a CSE flash instead of a normal one?
If not, do it.
If yes, you have to appeal to warranty without any problem, since your device has official firmware.

How to downgrade to kitkat or lollipop from any higher android operating system

Hi Guys,
I am back with another thread for people who want to downgrade their Android ROM for different reasons from any higher android version, like some of you getting problem with new O.S, some of you might not like the new O.S and as in my case my new o.s marshmallow got crashed/currupted.
As in my case when my new updated O.S 6.0 Marshmallow got crashed, then no way was left to me but to reinstall 6.0 M on my phone, but as stock ROM of marshmalow for HTC Desire 816 dual sim A5_dwg indian version was not available on any portal online, so i need to rollback to any lower version android like kitkat or lollipop.
As you guys must know that if your phone is running on higher android O.S then it doesn't matter whether its corrupted or showing errors, you can't rollback/downgrade to any lower version android.
For finding way to get out of this problem, i am sharing some steps which i followed to rollback my phone to lower android version.
Step 1: First of all please make ready your computer by installing ADB drivers, fastboot utility and drivers for your phone.
Step 2: As i have already made clear that you can't roll back to lower android version from higher one so for doing that you need to unlock your phone's bootloader , ROOT your phone by following this thread
http://forum.xda-developers.com/showthread.php?t=2775801 and install any custom recovery available like CWM or TWRP, i personally prefer TWRP.
IMPORTANT Note: For users who have rooted and un-rooted their phones in past, updated stock ROM to any new stock version and already having Unlock_code.bin file on their e-mail, don't try to use that file now again for unlocking your phones bootloader as it will not work, you need regenerate that unlock_code.bin file from HTC website because with updated stock ROM, code for unlocking bootloader also changes.
Step 3: Once you are done with Rooting and installing custom recovery and Super user app. now it's time to install any custom ROM like cynogenmod or any other custom rom available for you phone. For downloading and installing CM 13 follow links given https://download.cyanogenmod.org/?device=a5dwg
https://wiki.cyanogenmod.org/w/Install_CM_for_a5dwg
Step 4: Once you are done with installing custom ROM CM 13 on your phone now you can start procedure to Un-Root your phone, install stock recovery and flash any lower android version stock ROM on your phone.
for unrooting and rolling back to stock rom you can follow my thread
http://forum.xda-developers.com/desire-816/help/how-to-unroot-roll-to-stock-htc-desire-t3487894
and
http://forum.xda-developers.com/desire-816/help/guide-how-to-flash-stock-recovery-ruu-t3308502
Wollah....... you are now ready with lower android version ROM on your phone and now you can update your phone O.S with OTA updates released by your phones manufacturer.

[OTA][6.0] Marshmallow update available for OPPO F1s

I just now landed to this page and found official Marshmallow update for our oppo f1s
How to update?
*BACK UP YOUR DATA*
Just put the zip file in your sdcard and reboot to stock recovery and "apply update"
Warning : This update will factory reset your phone and wipe all data. I upgraded without backup and lost all my data!
Link to OTA:
http://downloads.oppo.com.s3.amazon.../A1601EX_11_OTA_001_all_201703281552_wipe.zip
The OTA is released for Australia but it worked on Indian and Phillipines phones. I have tested it on my phone.
EDIT: Seems there's a global version also http://downloads.oppo.com.s3.amazon...A1601EX_11_OTA_027_all_201701110933_local.zip
I haven't yet tested the global version.

No point in upgrading. There are no root options.

The update zip doesn't contain stock recovery, which means if you flash the OTA via TWRP [by modifying updater-script] you can update to MM and re-root from twrp.
I haven't tried it because twrp is not working on my phone for some strange reason. Probably because I have 4GB version

There seems to be a problem with the mirror server in Australia, which means I can't download it. I've contacted oppo and asked for a download link from another server

Marshmallow suck oppo f1s , Not appearing notification on status bar , Internet isn't working well n it's slow ,

Can someone help me?
I have updated my F1s to marshmallow however, I am unable to get the latest monthly updates installed. I have tried downloading the latest update (A1601EX_11.A.38_20190328) and installing manually, however that results in an error and fails to update.
It seems the recent update is for the lollipop rom. I don't want to roll back to lollipop as I have seen major improvements to GPU performance and battery life since upgrading to marshmallow.
Is there a way to get the latest set of security patches for marshmallow?

Hi. Had to make an account to answer you lol.
For some reason, OPPO stopped supporting marshmallow on the countries it was implemented. Philippines, however, did not effected the idea and would say, if you ever ask them, that their team is working on it. It's just a bunch of rubbish, we both know they're too busy with their flagship phones. F1s has long been forgotten and the only latest marshmallow update you could find is here, I'm not sure though.

Reverting from custom ROM to stock causes bootloops

Hi guys,
I have a problem I need some advice for. A year ago, I purchased my Amami for the purpose of GPS-navigation on my bicycle. It always worked fine and I was able to charge it with my dynohub without any issues. The charging is giving me a headache now though, and all troubleshooting points at the phone being the problem.
Now, a couple months ago I decided to ditch 4.4 and go for a custom ROM (I've tried Oreo and Pie) which worked fine, but the phone doesn't charge as well as it used to on my bike. I'd like to go back to stock to see if that's what is causing the issue and used the Xperia Flashtool to revert to a stock image, but the ones that used to work on the phone now give me bootloops after I've flashed TWRP and ResurrectionRemix and Lineage OS.
Is there anything I need to know before I flash a stock firmware with the tool? Any input would be appreciated.

Sounds like to have not updated to Lolipop and therefore you do not have real recovery. Is your bootloader unlocked? Then you can try EMMA to update to Lollipop.

My bootloader is unlocked, I have TWRP installed and am currently running Lineage OS (Android 8). It doesn't matter if I flash Sony's original Kitkat or Lollipop; both will have bootloops. No offense, but I'm not sure you understood my original post: I'd like to go back to an old stock ROM, because 4.4 is the one that I'm sure have me no trouble with charging on my bike.

Proper BL relock:

If you use twrp in fotakernel partition maybe necassary to write back original fotakernel.sin (inside stock.ftf) before relock with flashtool. Remember! After relock with flastool the new BL unlock key here: DEVICESERIAL \ unlock.txt

Downgrade from OOS 9.0.6 to OOS 4.1.7

I'm running a completely stock OP3T with stock recovery and locked bootloader and latest OOS 9.0.6 installed.
Lately the phone has been unbearable to me and keeps hanging a lot with random crashes so im thinking about downgrading to OOS 4.1.7 as it is more stable. (I prefer OOS over custom roms to maintain stability and keep all the phone features intact).
I've downloaded OOS 4.1.7 from [oneplusupdates dot com] (cant post links cause im still new)
My question is : can I use the built in software update to locally select this file and preform the downgrade directly from pie to nougat?
I read somewhere that this could brick the device so i wanted to make sure.

Yes, that would surely brick the device. There are other steps involved before and while downgrading. Search on XDA for the steps.
The simplest solution to your problem is to download the current (9.06) OOS ROM and clean install/sideloading it. Your problem is most likely because of OTAs and not because of 9.06

The phone has replaced your bootloader to the point old roms are no longer compatible. Finding the correct zips and flashing order to downgrade the bootloader is a route i would not advise either. The easiest way to downgrade is find the msmdownloadtool unbrick thread of your specific model and download the version you desire or lower. Use this tool to flash the included files in upgrade mode and you will be on a stock, locked bootloader with the version you chose to download. Flashing always carries a risk, but i had no issues downgrading this way while i did run into issues flashing old zips. I switch between 5.0.8 based roms and the latest roms and its never let me down.
