Help! Poor GSM signal and 4G/LTE after latest OTA update - Galaxy S6 Q&A, Help & Troubleshooting

Hi, I used this s6 (G920F) for more than a year without any issues. Few weeks ago I got an OTA update and since then the phone rarely goes to 4G mode (it almost always used to be in 4G), often stays 'out of coverage' and drains much more juice from the battery. I confirmed the phone is faulty by swapping the SIM over to another phone. This is the currrent config: AP: G920FXXS4DPG6, CP: G920FXXS4DPG3, CSC: G920FOJV3DPF3. Country code XSG, Status: Official, Knox: 0x0.
I already tried these:
Factory reset, Factory reset and wipe in recovery mode. Nil fix.
Emergency recovery/Re-initialise using SmartSwitch. It re-installed the same firmware with the same issues. Nil fix.
Numerous attempts to flash the previous firmware (G920FXXU3DPER_G920FOJV3DPF3_G920FXXU3DPF2_HOME.tar.md5) using Odin3.11.1 with this result:
<ID:0/005> Added!!

Flashed the current firmware using Odin (Passed), wiped in recovery, boot up, the same issues..
Has anyone experienced similar issue? Got any fix? I am out of warranty and have no problem rooting etc. if I must.
My primary intention was to restore the previous stock firmware, but it seems the bootloader will not allow this. Is there any workaround to bypass this block?
Could someone please help? Thanks!

If your build is from july you can't downgrade, it can be a software problem only if your phone has been unlocked before update

Sorry, didnt get that fully. It's international version, 100% stock no mods, no SIM or carrier lock.

You can't flash the previous firmware. You can try flashing the latest firmware through odin and check if it makes a difference.

Download this firmware and flash it.

Samsung has blocked downgrade since july 2016, so if you want to flash same version but older by release you will not succed, there is no way to flash older version at the moment

Tried it a few days ago, no luck. It flashed good, but booted up to the same problems.
What if I root and use a custom recovery? Will I be able to flash the previous firmware?

Nope. I'm afraid you're stuck with the latest version. You could try a custom kernal like Space-X and see if it solves your problem

Thanks, will try and post back

Can I flash another stock firmware newer than current, from another region/CSC..? If so, could you suggest one? I see many other regions already got August updates. Hope the updated FW would fix my problem. I am impatient coz I have holidays planned for next week. Worried about travel with broken phone!
I sent a mail to Samsung about the issue, they want me to give it to the service center, I dont think I should.

Tried connecting with Kies and Smart switch, none can find the device just keeps buffering and for smart switch it just say it's not supported. I am able to get into downloading mode, but that's it.
Got newest Kies, odin 3 v.10.7.exe however on my first go i noticed i had odin3 v.10.6 but now i got the latest i believe. After reading around i decided to try to fix it back to normal, so i downloaded my countries [sweden] firmware this one: http://www.sammobile.com/firmwares/confirm/57869/G920FXXU3COI9_G920FVDS3COI6_VDS/

And now i am here, i am truely nervous that i wont be able to get it to work.

Ps. Worth mentioning, sometimes my usb is not recongnized and it flickers on and off (connectiong) but seems
to be fine most of the times and during the odin trials.
To root your phone, couldn't you simply flash twrp and then unikernel, like the guides say?
However, I'd try doing the following:
First of all, download the stock firmware for your version from samfirmware, then flash it via Odin (make sure the versione you download is the same you had before, or at least a more recent one).
From your logs, the problem seems to be pit file, so try reading here http://forum.xda-developers.com/showthread.php?t=1916936
If not, completely delete odin and download it again, maybe trying with a different firmware.
If everything goes well, let it boot into setup wizard, then you will able to root it again, this time following the standard procedure with odin:
- Make sure "Auto reboot" flag is NOT checked;
- Flash the twrp odin-flashable file (can't post links here, but you'll find them in General section);
- Manually reboot into recovery (Hold power+home+volume up).
- Once you're into twrp, flash unikernel and reboot.
Your phone will be rooted

I just begain with youtubing easy way to root and i just said download odin, get the right firmware plug in an click odin.
That has failed and it's bricked, however i have tried to get my countries firmware, it didint work and produced my last log that i posted.
I am downloading another one there is two for Sweden however the other one says Sweden tre which is an operator over here and not one that i use so i doubt that will work?
i will attempt to download it but it takes 3h due to the limited speed at sammmobile.
So summarize, the sweden firmware from sammobile failed ;_;
What i do is, put phone in download mode, open odin, get the AP [Sweden from sammomobile] it finds it and press start, quickly after it says failed and i am back to square one.
I was reading the link you gave me about the pit files, it appears the error could be related to me having the wrong firmware?
I am seriously offering a bitcoin tip or a paypal tip to whomever helps me get my phone to work.
There are firmwares here for VDS.
Uninstall Kies and reboot your PC before using Odin.

Should i try all of those or just take the latest?

If you were on 5.1.1, then get 5.1.1
You can try the file you dl before. Just uninstall Kies before using Odin.

You dont need to download another rom dude...the problem is your usb dont get recognized and after a while it will disconnect...it happened to me aswell...searched on youtube did an easy fix and then i flashed stock rom with odin and joined marshmallow beta...
Tldr: search on youtube a fix for usb not recognized...i dont have a link sorry you have to search it by yourself its an easy fix..
Is it OK to flash with the latest stock roms? G920FXXU3? or should I flash only G920FXXU2? they are both 5.1.1 anyway.. If i flash with G920FXXU3, can i downgrade it to G920FXXU2? thanks for any help

You're fine with either.
@WaDoDem
First of all, calm down. Believe me it's harder than you think to brick S6 in a not fixable way
If Odin doesn't flash official roms or you just cant suffer a slow a** download speed from SamMobile :
1. Press and hold all of 4 buttons on your device. (Volume up + Volume Down + Home + Power) your device will reboot.
2. As soon as device reboots release volume up and hold other 3 three. (Power + Home + Volume Down). Your device should boot into downloading mode.
3. Download this :
https://dl.twrp.me/zeroflte/twrp-2.8.7.2-zeroflte.img.tar.html
4. Connect your phone to your pc and flash above file with Odin. As soon as flashing process finishes, hold Power+Home + Volume Up. Now your device will boot into TWRP recovery.
5. Wait for drivers to be installed. Your pc should show phone's internal storage as connected device. If not, go to TWRP Mount section and enable MTP mode. (Or if it's enabled, disable and re enable it )
6. Download this rom :
http://forum.xda-developers.com/gal...rom-2013266107-arrow-rom-v1-0-0-fast-t3212318
And this kernel:
http://forum.xda-developers.com/gal...nified-development/kernel-vindicator-t3156281
Then put them on your phone.
7. Wipe system,data,cache and dalvik cache from twrp.
8. Install Arrow Rom first and then flash Vindicator Kernel.
9.Reboot, first boot can take up to 15 minutes
10.Continue celebrating new year [emoji14]

sometimes if odin not working i restart my computer and put my mobile in downloadmode again and than i try again,most of the time it worked.....
If you think you can't find a wat at all, Samsung will help u. Download smartswitch to your PC and you can click in top corner emergency reinstall (or something like that) just put your serial number (as found on your backside of the phone)
4. Connect your phone to your pc and flash above file with Odin. As soon as flashing process finishes said:
Odin cant find the tar file.
I got odin 3V3.10.7 in options auto reboot and f. reset time are all bocked in is that right?
On files to download i am able to do, ap,cp,csc,bl neither of those help to find the recovery image that i am supposed to start?

I cannot use recovery since none of the numbers i have on the back of my phone matches the one i need to enter.
i tried device initialization that led to FAILED TO UPDATE DUE TO AN ERROR.
and then smart switch recommends emergency software recovery the one you were talking about but i dont know how to get my code.
I assumed you meant to input my phones IMEI however that did not prove to be correct.

Relax, flip your phone and on the bottom you'll see (barely visible) text. The last line it says: 'S/N:'
The code after is your serial number. So not your IMEI
The same code is found on the stickers you'd got with your phone

When i go to Smart switch Emergency Software recovery and input my S/N R58G52AMP1J
it says:
''Unable to find the recovery code. Check the recovery code in the PC's Emergency Software Recovery menu, or contact the samsung service center.''
When i did Device initialization used my model nr and S/N: R58G52AMP1J, halfway through completing the process, the first one did 100% then the next loading didint start got the error and that re-directed me to try Emergency Software Recovery.

If Odin says no PIT, he'll need to Odin the PIT file for his device first then Odin the factory firmware.

You don't need to flash the old bootloader anymore to flash TWRP.
Just flash this via Odin, and TWRP will be installed on your device;

I cant unroot my Galaxy S7 Verizon (SM-G930V)

I rooted my phone with odin and i decided later that i wanted to unroot it. So i went into SuperSu and went to settings and tried the full unroot thing. My phone restarted and everything and i went to the root checker and it said i was unrooted. Then, i was still getting the Security notification that always pops up saying " Security Notice: Unauthorized actions have been detected ". So i went to that and i decided to try to factory reset my phone from that screen. So I cleared all the data on the phone and everything and it came back completely reset. The only problem was that I am still getting the notification. I have no idea what to do to get rid of it and i want to completely unroot my phone. I have looked all over the internet for the Galaxy S7 Verizon stock firmware. I can't find the firmware anywhere and its really bugging me having that notification there still. If there is no unroot available for the S7 right now, i was wondering if there is someway i can hide that notification for now to give me peace of mind. Thank you so much in advance.

Hi mate
Just flash a stock rom with odin on top of it
http://www.sammobile.com/firmwares/database/SM-G930V/
back up everything important before you do it ..just in case
Hey, i have a whole new problem now. When i was trying to unroot my phone, i accidentally installed the wrong firmware on to the phone. I turned my verizon phone into a t-mobile phone.
Im not exactly sure what flashing is, but is it where you put the BL, AP, CP, and CSC things into Odin and start it?
I might have already done that because i found the verizon firmware somewhere and when i try to do it in odin. It gives me an error and says fail.

Hi
Yes you need to flash it with Odin
did you downloaded from sammobile?
if not try i from there , follow their instructions :
Extract (unzip) the firmware file
Download Odin v3.11.1
Extract Odin ZIP file
Open Odin v3.11.1
Reboot Phone in Download Mode (press and hold Home + Power + Volume Down buttons)
Connect phone and wait until you get a blue sign in Odin
Add the firmware file to AP / PDA
Make sure re-partition is NOT ticked
Click the start button, sit back and wait few minutes
Usually sammobile has only one tar file ( unzip it just once) , back up you photos and files before just in case
Check this thread is not for your phone but the basics apply to all samsung phones

Im not exactly sure what flashing is, but is it where you put the BL, AP, CP, and CSC things into Odin and start it?
I might have already done that because i found the verizon firmware somewhere and when i try to do it in odin. It gives me an error and says fail.

Can you post a pic of the back of the phone showing the model number as SM-G930V and FCC ID. Then take a pic of the bootloader screen and show what what model number it has, if flash successfully it should be showing as SM-G930T. If proven true then it may seem that as the S7 is a Universal Hardware phone (QCOMM that is).
Please Help
I'm not sure if this is the right place to post, but I have a similar problem.
I tried flashing SM-G930U to my SM-G930V.
Odin failed, and I rebooted my phone. It will only reboot to download mode or recovery mode.
- I have tried redownloading files to check for corruption.
- Using different versions of Odin.
- Flashing to the stock files, which also fails.
- Using stock USB cable.
- Using different ports.
It doesn't seem like Odin will flash anything
Benaiah1287: I am in the exact same predicament...
I got the G930U firmware from sammobile and have tried flashing it with Odin versions 3.10, 3.11, and 3.12, all with failure.
My next steps are to try the stock G930V firmware or to see if the Samsung Software Upgrade Assistant can repair.

You need to use the prince comsey's modified odin that bypasses SHA verification.

I hunted down the Comsy version of Odin 3.12 Odin3_v3.12_PrinceComsy.zip (MD5 hash 136E707B39C2E4CDC47820C68065CD5C)
but I still received a failure with the following output:

I also tried it without copying the BL file only, as I have also read that this could work, but no dice.
I then tried the stock G930V firmware (for my G930V) with the following result:

on reboot it gave me the 'Software Update Failed' screen
I then used the Samsung Repair Utility and after half an hour it was able to restore the original OS. It did give me a new warning about it not being able to make calls until it was set up with a Verizon account, but after reboot it still just has the message "SIM card is not from Verizon Wireless," so I'm assuming it is still in its original "factory unlocked" state.
So, about 8 hours of tinkering later, I cannot recommend trying to flash the SM-G930V at all.
My sole purpose for all this was in trying to get compatibility with Republic Wireless (which claims it supports the unlocked S7 but really means the North American 930U only).

You are trying to flash a downgraded bootloader version/firmware. Your phone has bootloader v4 and you are trying to flash a v2 firmware. Flashing a v4 or above will work.

For anyone keeping up, the source of the 930U with bootloader version 4 is here
...which I found through Fix For Those Who Tried Flashing The g930u Firmware
Too bad I just ordered a G930U instead thinking there was no current release
It appears it was also uploaded to sammobile just yesterday...but I am only assuming because the naming convention does not agree to the guide I found here, and I don't understand the 'PL#' part

I am having the same problem. How do I know the version before trying and failing until I get one that works?
Couldn't the boot loader 'version' be changed/hacked within the (down graded) boot loader so the version check would pass?

After that, I follow this thread [ROM] [8.0] [OFFICIAL] [CRGB] [ODIN FLASHABLE] For Galaxy S8+ [G955F/FD] [08.09.2018]. Everything was ok, I received an OTA didn't remember the version and continue configuring until I install the Magisk.apk and restart the device, the device stays on OEM boot loop again, trying to reflash S8+ Official Oreo CRGB Firmware 07.09.2018 this version, comes the error SW rev. check to fail device 4 binary 3 related that I am trying to use an older version.
So I find 2 newer versions: SM-G955F_1_20180904043214_2afttpa4az_fac // SM-G955F_1_20180904010814_39o648ohci_fac. Try and now the error is the Kernel rev.
Hope you can help me with some guideline here.

As you have already guessed you are trying to flash older firmware than what is on your phone. Device 4 = current bootloader version on phone.Binary 3 = bootloader your trying to flash.
Have a look through this and use samfirm to download latest firmware then flash with odin. Or download latest from sammobile and flash.
When looking at firmware names the 5th number from the right is the bootloader version number.You will need version 4 bootloader firmware.

Anyway to flash older firmware once the device has been updated?
Used to be absolutely fine on older devices, could rollback and flash any firmware you wanted.

your best bet is to go to sammobile.com/firmwares and download the latest FW for your device and flash it with Odin. I bet itll boot right up barring any hardware issues

GT-N8020 - Not booting - no Recovery - need access to data

I need some troubleshoot tinkering
I have received a Note 10.1 (GT-N8020) from a friend who would appreciate if I could salvage pictures and documents that was on this tablet, and let us not debate his backup options.
Problem with the tablet is it wont boot properly.
It just hangs on the Samsung animation.
As first troubleshoot step my thought was to boot into Recovery and wipe cache and dalvik, just to get it booting. But I simply cannot boot into Recovery. I can only get to ODIN mode.
After several attempts giving up on Recovery, my plan was to flash a new Recovery onto tablet by using ODIN mode, however all attempts both with several different version of ODIN and different version of TWRP fails to be flashed.
Code:
<ID:0/009> Added!!
<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..
<OSM> Checking MD5 finished Sucessfully..
<OSM> Leave CS..
<ID:0/009> Odin engine v(ID:3.1401)..
<ID:0/009> File analysis..
<ID:0/009> Total Binary size: 6 M
<ID:0/009> SetupConnection..
<ID:0/009> Initialzation..
<ID:0/009> Get PIT for mapping..
<ID:0/009> Firmware update start..
<ID:0/009> NAND Write Start!!

<ID:0/009> FAIL!
<ID:0/009>
<ID:0/009> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
So here I am, feeling stuck.
Either I am thinking there is a defect with the NAND chip, why the tablet must have failed in first place, however I can also find some articles claiming some of Samsung's tablets does not have a Recovery mode/partition, is this true for this model?
I have not reflashed entire tablet, since I need access to whatever data there must be on the tablet.
I also found description on sammobile explaining how to re-install ROM while preserving apps and data, but they keep mentioning ROMs based on 5 files (AP, BL, CP, CSC, HOME_CSC), while I can only find ROMs based on single files (AP)
Link to article (see step 2)
https://www.sammobile.com/samsung/galaxy-note-101/firmware/GT-N8020/CNX/download/N8020XXUDOH1/55623/
Anyone know where I can download such ROM based on 5 files (Samsung official ROM)
Suggestions for any other methods I can try to get the data out of tablet?
Try Philz Recovery instead of TWRP .
Not sure if ADB will work for you .

IIRC would that not require USB debugging enabled (which I cannot since it will not boot) and the Android in a running state?
Thanks to the SamFirm tool I managed to find some ROMs configured with CSC_HOME. On first shot it failed to flash these ROMs too. But I will try some more tinkering
I guess your eMMC is locked.
So the only possible solution would be to desolder it and read the data directly out of it.
Whereas the OP gives a link to an "article" at sammobile, that page has since changed and no longer gives any useful instruction for re-flashing while preserving apps and data. However, I believe that the original "step 2" of that page referred to was : "2. Add each file to its respective field in Odin v3.14.4. Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data."
Probably a bit late for the original poster from 2020 .
Could try flashing with No CSC .

Sure, there's a good chance that the original tablet has since become e-waste, however, there is also some chance that it's sitting in his friend's drawer in the slim hope of a resolution.
However, my clarification about "step 2" is for the benefit of other readers of this thread, since the OP will already know this information.
My own GT-N8020 tablet has the exact same problem. I was able to overcome the flashing difficulty by using the Prince Comsy patched version of Odin 3.12.3 (which disregards spurious USB communications errors that tend to occur).
However, re-flashing without the CSC portion of the firmware doesn't resolve the problem. I can't include the CSC portion as this will clear the data that I need to recover, and I haven't yet been able to find a HOME_CSC alternative.
Joe.
