UMIDIGI F1 NVRAM problems loss of RED connection - Android Q&A, Help & Troubleshooting

I have a UMIDIGI F1 since I was on the market and I was very satisfied, I put TWRP ROOT and everything like silk until ..... in the July update I could not flash any of the existing TWRP so far and in one of those Attempts appeared to me the warning or whatever in violent red and with parts in Chinese (attached a couple of screen copy) the serious thing is that NVRAM began to give problems and has failed to recognize IMEI even having "recovered" them with tools such as SN Writer and others based on META.
Is there anyone who has happened to you and in that case what was the remedy ?.
Or maybe someone could provide me with the NVRAM folder that I would already update my IMEIs and MAC

Can anyone tell me the situation of the NVRAM folder inside the ROOT tree? It would be helpful to see if I can solve my problem. The SN Writer tool gives me "PASS" in green, but I continue without having access to the SIM cards, it does not detect them.:crying:
Better suggestions are welcome.
Thanks in advance

[Q] IMEI is correct but no network detected MT65xx

First I'm so sorry if my question is similar with another threads. But I'm pretty sure I have been looking for the answer around the internet and of course XDA developer for a week. I follow every guide and method I found. But it still not answer of my problem.
I flashing camera driver I've got from my friend backup using TWRP backup. Actually I only need to choose uboot only to install. But I'm in hurry so I accidentally choose everything includes NVRAM. Since then I've got wrong IMEI on my phone because the IMEI overwritten with my friend phone. But it's not a problem because I can restore my original IMEI with MTKDroid & Tools.
And the problem is my IMEI is now back and corrected. But there is no network detected on the phone. SIM card detected fine. When I go to EngineerMode by pressing *#*#3646633#*#* and open Radio Information on CDS I saw IMSI field was unknown and Radio Status is turning on and off rapidly.
What I have done is :
1. Full flashing with the stock ROM via SP Flash Tools.
2. Change the IMEI with MTK Droid Tools
3. Change the IMEI with AT command ... echo 'AT+EGMR=1,7,"myIMEI1"' >/dev/pttycmd1
No result. IMEI is correct but no network.
I believe this is not a hardware problem, so please help me to solve this problem. Because it's my only phone to communicate with my whole families. I really appreciate with your help. Thanks.

I WHOLE formatted my Cherry Mobile Fuze Q390 (MT6582) with SP Flash Tool. Then I flashed the official firmware of this device with SP Flash Tool. I don't have any backups because I am reverting to stock. Now the phone works fine but it does NOT detect the SIM card. Also, the IMEI is shown as "INVALID" for both SIM slots when I input *#06#. When I try to fix IMEI from MTK Droid Tools it shows (ERROR : pttycmd1 device NOT found!). Also, MTK Droid Tools shows (Baseband V -----). I am sure the problem is that when I formatted the phone it wiped the NVRAM region too. So the device has no baseband or radio files right not and also the data/nvram/md folder has nothing in it. Although, WiFI still works perfectly except the annoying NVRAM Warning that I kept on seeing when ever that I wanted to connect to a network. Now the official firmware of Cherry Mobile Fuze Q390 does not contain any nvram.bin file. It does contain the BPLGU file but I can't seem to modify IMEI with SN Write Station, Maui META 3G, IMEI&SN Writer V1.5.3 and etc. I tried using the MTK Engineering mode mode also and tried to write it using the AT+ code but it keeps on saying failed to send command. Probably the SN Write Station, Maui META 3G, IMEI&SN Writer V1.5.3 and etc. only modify the IMEI when the baseband or radio files are already present on the phone. So I think the only way out for me is to flash a nvram.bin using SP Flash Tool or Flash nvram.bin+nvram.tar to MTK Droid Tools which I don't have. Any ideas whether I am on the track or not? If I am, then how can I get the IMEI back on my phone. As you people can see that I have tried a lot of things, so please suggest/advice accordingly and any help would be greatly appreciated.

[Q] MTK MT6582 IMEI repair failure

Hello XDA, I have been a user/fan of xda for about 5 yrs now. But I havent found a single problem that I didnt find the
answer for here on xda, or somewhere else (Google). I have a Computer and Phone repair shop in Ethiopia and I used the
internet and mostly XDA to Unlock Sprint HTCs, Unbrick Galaxy S/ SII/ SIIIs, repair corrupted efs partitions, install
custom roms like CM (on almost every smartphone I come around), fix bootloops of Best devices like Xperia Z, Galaxy SIII,
Sim unlock Moto Droid ...
But I have faced a serious problem and have been trying to solve it for about three months now.
To the real problem
There Are these MTK MT6582 Devices, Mostly Huawei devices (G730, G610, G630) and they are recently getting a major IMEI
failure (IMEI : null). I have tried through the ff methods (that I use for other MTK devices like MT6572, MT6575) With no
luck
1. Maui Meta 3G - It reads the devices in meta mode
- It can read the version (in "Get Version" window)
- I have selected the Nvram database of same baseband
- It fails to write the imei when I click "download to flash" It either replays "Check the load and device versions are the same (ish)" or "Download to flash time out"
2. IMEI & SN Write tool - Doesn't seem to read the device in meta mode.
3. MTK Droid - Rooted the device
- Restored "nvram" from another working phone
- Rewritten the IMEI
- Still the same (IMEI: Null)
4. Reformatted the whole device and installed firmware with "secro" file - Still the same - tried the above methods again, still the same.
Dear XDA Fellows, I am exhausted with these devices and they are keeping coming. So, Please help me solve these problem. Thank You.
P.S - I dont know where to post this, if there is another appropriate thread, lead me.

Problems after unbricking a Zenfone 3 Max

Hello I have Zenfone 3 Max ZC520TL. Recently, I bricked the Zenfone. Luckily I figure out how to unbrick it and it worked successfully. The inconvenient that I have right now is no network signal due to unrestored NVRAM and NVDATA. So what's the problem here? It's impossible to root (I tried a lot of methods and nothing), I cannot open the bootloader (open the bootloader to install the TWRP and restore) due to null Serial Number (I guess). So I need to restore those Nv's (I have those Nv's saved, backuped) to put on work my network signal and data
So, if someone knows how to solve this, please help me
Thank you!

MTK imei lost after flash stock rom / TCL 30 XE 5G

So i sucessfully rooted this device maybe 2 weeks ago... however bricked it trying to modify build.prop ( i still dont know how to mount system rw on this device)
so when i didnt have the firmware backed up i kind of was stuck so i ordered a junk phone off ebay same model but imei was blacklisted i did a full backup of the firmware and was able to unbrick my original device.. however the problem i face now is that it also copied the IMEI number from the ebay one onto this one.... ive tried numerous imei changer apps , tried clearing nvram nvdata, all that stuff but still it has the imei from the ebay device..... Im not asking how to change imei number persay because i know that is frowned upon and iilegal in some countries... but is there any way to restore the devices actual imei??? its a MT6833 ( mediatek dimensity 700 5g k6833) TCL t767w (30 XE 5g)
do i need to erase all paritions before flashing to get my imei number back? where did i go wrong? when flashing the ebay phones firmware should I not have flashed a certin partition pertaining to the imei ?
any insight or suggestions i thank you in advance
I can't help you with your question, but if you don't mind how did you root the phone? I'm trying to do this myself with no luck. My phone doesn't boot in bootloader or fastboot. It used too when I first bought it but after ota update it went away
with correct drivers installed (mediatek) you can use mtkclient gui or mtk meta tool... basically have your phone turned off have the program running on computer and plug your phone into the pc and it should automatically detect it or you can hold down all the buttons and mtk client gui should pick it up, load it up, from there can unlock bootloader and , backup firmware, flash firmware and so on
