Hey guys, i am looking for some help on how to upgrade my rooted s7 edge from MM to Nougat.
First of all let me tell you that I bought the phone used and rooted, it worked perfectly for some time until one day it had the Custom Binary blocked by FRP error. I tried to fix it by myself flashing a new rom. Everything worked fine except for the Signal and Data. I didn’t have any. I couldn’t fix it so I went with a guy that repairs these things. Nowdays I have the phone working on MM, but I would love to have Nougat.
I don’t know exactly what he did to make it work, I just noticed the phone has another IMEI and SuperSU with ADB Shell on it.
The problem is that the man told me I cannot update to Nougat or the “fix” he did would stop working. I want to know if there is a way to do it because I want to have the latest update.
I would just go stock and upgrade.
ok so i just got this phone coming from s5.its on the latest firmware QC5. the nougat root worked flawless and was able to flash things with flashfire..well messing around i flashed twrp just to see what would happen.well now it wont go in to recovery at all and the first time it did the l9ck said it was on..everythinh else still works still rooted.my qiestion is how to fix this? do i have to factory reset and start over or if i can find the lateest firmware and flash via odin?any help would be appreciated...
hey guys
i just brick my phone (no idea how, flashed android 7 firmware) after flash my phone was working for like 2 hours, then i let himself update a security options. After update my phone went brick
As far i found :
- installed Qualcoom QDLOADER 9008 driver
- found QFIL programmer
i need to have programmer path (something related to JTAG) and build xmp path
Where i can find them? Or is it a other way to resscue my phone?
I feel your pain. My timeline:
- The phone was unlocked but still in Stock Nougat (7.0?). Got that from OTA in Brazil.
- I tried to update to LineageOS 7 via TWRP. After a full wipe (everything, system, data, card, cache etc) I installed the new ROM. Turned on, bootlooped forever.
- Searching around I found out that there was no modem in the Nougat roms and for some reason I needed to flash a Marshmallow modem for my region to make that work (I think there is no Nougat modems around or something).
- I found a LA_DS modem for 6.0, flashed that using TWRP, still bootloop. Tried other roms using TWRP, still bootloop.
- I then downloaded a full stock old 6.0 firmware to go back to stock but the phone wouldn't accept some files ("preflash validation failed").
- Searched around and found out that you can't downgrade a bootloader from Moto.
- Using fastboot, I flashed the files the phone was willing to accept and it finally booted the 6.0 Marshmallow stock rom, but with no networking (radio/modem/baseband/IMEI missing).
- Flashed the 6.0 modem for my region again and everything worked. Connected on WiFi, dual sim cards detected etc.
- I started to install every update the phone showed to try to update it back to latest MM version.
- The three first updates went ok, the fourth turned off the phone to never turn on again.
Looks like there is no way out of this. My phone is pretty old and MotoCare in Brazil will charge a lung and a half for repair.

Pretty similar situation on my part. I downgraded back to 6.0 and when it tried to take the December update I ended up with the same thing as you. I ended up getting a replacement from Moto for under 100 dollars which was worth it rather than trying to find a solution that doesn't exist.
Hi,
I recently installed stock Nougat on my phone after being on LineageOS for some time. After installing, I noticed that I no longer had LTE or any data whatsoever. I can still connect to cell service, send texts, etc, but no data. At this point I'm desperate to get data so please let me know what I need to do to get back a data connection. I want to try installing a ROM on it to see if it's just a stock Nougat problem, but I'm nervous about that as I've heard it causes problems with the Nougat modems. Any advice?
How did you install the stock Nougat ROM? Via fastboot from the thread in my signature? If so, you need to do it again because the radio flash failed... if some other way, you likely have a kernel/radio mismatch causing this issue. Marshmallow radios are not compatible with the Nougat kernel, and Nougat radios are not compatible with the Marshmallow kernel.
I have migrated to TMobile and am trying to reflash my unlocked S8 Active from Sprint to TMobile mainly for wifi calling functionality. The phone was already running Android 9.
I downloaded & flashed the latest TMB firmware from sammobile via Odin v3.14.4 per the instructions on sammobile.
I flashed all the files including CSC and Userdata to ensure a complete wipe and flash.
I even wiped the cache and performed a factory reset after the firmware flash. The phone has been rebooted multiple times now since the reprogramming.
Unfortunately when the phone starts up I still get the Sprint flash screen and I don't have the Wifi Calling option available. The phone shows the latest TMB software is loaded (G892USQS6CTB2) however it still shows software ownership as Sprint (SPR/SPR/SPR).
Any advice on what I should be doing differently? Thanks!
It's a bit old to bump, but I'm in the exact same boat. Anyone have a fix for this?
I also am in the same boat: I want to use my SM-G892A on T-Mobile with wifi calling enabled. Many rooting resources say rooting this phone is not possible, but apparently on Sammobile there's instructions. I could not find them though. Any pointers appreciated.
