hi guys, i want to ask something, i am having serious issue here! my phone was running android 4.1.2 but having no imei and unknown baseband. some thread stating if i was downgrading my fw, i will be having lost imei and unknown baseband issue, but in my case, the only fw that working was just android 4.1.2, and in my country, my phone was supposedly running on android 4.3. but when i am trying to install stock fw, i got a bootloop state. i have tried different method as such using xperifirm to download stock fw and updated fw, using pcc, but still suck in bootloop.
and my another question was, when i tried to relock my bl, flashtool showing different imei for my phone.

Hi, a while back i debranded my fathers c6606 and flashed c6602 firmware for he can be on 4.2.2, i flashed the FTF using the flashtool and left out the baseband for he can still receive LTE but yesterday morning he accepted the .244 update and now doesn't have LTE. ive tried to flash the baseband of the t-mobile firmware, tried reverting back to stock, and also tried c6603 .244 but the flashtool keeps saying error flash aborted. any help would be appreciated

Hi all,
I'm running a Huawei P9 with a build number of L19C900B190. I am not rooted, bootloader locked. Having an insane time trying to find a way to upgrade from Marshmallow to Nougat. I can't find any other C900 firmwares, so is it impossible for me to upgrade? In my desperation I have finally resorted to opening a new thread. Which regions received the C900 firmware? I am based in Singapore.
I understand another method i can go is to unlock my bootloader, root my phone, flash another oem firmware like C636 or whatever and then upgrade to Nougat. However I am trying to find a method that can keep my warranty intact as my device is just a few weeks old. If anyone can point out a firmware i can flash Nougat for my phone type via the dload method, I would be really grateful.
Hi,
Just sharing my experiences with you.. I had the same problem as you. Tried to flash C636B190 firmware from stock firmware (which is customised by Starhub I guess Cause build number is L19 C20B150 and I can't find any info for C20 build) and end up having C900B190 installed. Regardless of how many times I reflash, build number stay with C900B190 instead of C636B190. Although I had the B190 build, but fail to install Nougat update via Hisuit.
You can try to use Hisuit and PC to update to Nougat, see either it will fall at 1% or not. No harm will occur on your phone.. I tried many times. After giving up, I just send the phone back to service center and revert back to their original firmware.. And to wait for OTA.
Good luck...
I ended up sticking with the C900B190 FW as it's a pretty stable firmware for marshmallow. I've read around and with some help, found out that only way to go to nougat is to debrand to a C636 FW and then upgrade manually.
Hi.
I have Note5 at&t and it has Bootloader.
When I was trying to flash another stock at&t firmware, I've lost my IMEI number. As I learned, in order to get back my IMEI, I have to flash my old firmware, but I didn't memorize my old firmware name. And because of the bootloader, there is no way to learn old firmware's name with the root access. I can't root my device. Is there any solution?
Thank y'all in advance.
hi, i have the same problem, tried to downgrade to marshmallow but got an error, i flashed stock AT&T nougat firmware and now have no imei info or baseband info, i have tried flashing n920aucu4eqk6 and n920aucu4eql1 which are the 2 latest firmware versions but still having same problem...help! please
in case this helps anyone, i managed to solve my issue, i downgraded firmware to a 5.1.1 combination firmware, where the baseband and the imei were still being picked up by the phone, then i reflashed the phone with PK1 marshmallow rom (except i did not flash the CP file), only flashing the BL, AP and CSC files and now the phone is running marshmallow and picking up the imei and baseband information and can make calls and send text and picture messages.
thank you
I'm using a Galaxy M20 (m205f). Trying to root it, I somehow messed up the radio and efs partitions. Tried to install the latest stock Rom and it updated the binary from U4 to U7 with a null IMEI and unknown baseband. The IMEI repair softwares need the modem and the modem version presently is of U7 binary which is pretty recent and no IMEI repair tool supports this modem version yet. Is there any way I can downgrade the modem? There's no lower Android version and no combination file for the U7 binary on the internet so I'm stuck. Can I somehow put an older CP/Modem (from lower binaries) and make it work with the latest firmware?
