[Completed] [Q] PLEASE HELP IMEI null and SIM not recognized, nothing works

Hello,
My phone: GSMART Roma R2 (Rooted)
I know there are a lot of threads how to restore IMEI but none of them worked when I dial up *#06#, it shows message with two lines containing "null".
I was using MIUI rom for a while and suddenly after I rebooted phone SIM was no longer recognized (before reboot I was playing with SWAP couldn't make it work so I uninstalled BusyBox (could that cause the issue?))
I already tried:
Engineering Mode: Displays "AT command is failed to send"
Terminal Emulator: Doesn't work
MAUI 3G: Flashing new IMEI changed nothing.
MTK Droid Tool - Changing IMEI did nothing.
SN Writer: Writing new IMEI changed nothing BUT when I choosed to read IMEI it successfully displayed both IMEI in the textbox. (So it looks like the IMEI actually is registered on the phone but phone doesn't seem to use it)
Manually writing MP0B_001 to NVRAM: Nothing changed.
I have used backup in CWM recovery to stock ROM, didn't work, then I did factory reset, didn't work, flashed back the stock recovery and installed update from Gigabyte site, didn't work. So basicly now my phone has stock rom, stock recovery, factory reseted and is rooted.
Thank you very much for any answers because I just fell hopeless about fixing my phone

[Completed] Micromax A110 eMMC Corrupted or Partition Overlapped!

Its been more than a month that I have been researching to rectify my Phone's flash.
I download several tools like fastboot, adb etc (these two by the way disappears in a flip of second as I open them). My phone is hard bricked but By luck Its detectable under COM ports in device manager.
I have SP Flash Tool (Old and new version, both encounters the same problem during Flash process). when I flash it says "BROM ERROR: S_DL_PMT_ERR_NO_SPACE(5069)" which I think is a problem of eMMC. By research, I found either eMMC is corrupted or damaged or there is a partition overlap in there.
Also, formatting by means of SP Flash Tool, can't help it.
When I run a memory test in SP Flash Tool, it fails to complete eMMC Pattern Test.
Please, Help me out to bring my phone back to life!
Thank you.

[Completed] Doogee X5 Pro Bricked

Ok, i have a doogee x5 pro phone and i tried to root it by flashing twrp recovery using sp flash tools. While flashing i got the error "PMT Changed for the rom it must be download". So i did a small research on internet and i found out that i needed to format everything except bootloader. This succeded. So after that i tried to install the firmware with this succeding to. Unfortunately the time i tried to turn phone on it was dead. SP Flash Tools wont detect it anymore. Please help me cause the phone is not mine and its brand new! I can rate my self as moderate android user. :crying:

i think i have a bigger problem... I downloaded a stock rom for doogee max pro(cause i just realised it wasnt just pro it was max pro) and it didnt seem to be recognised again. Any help would be appreciated. I constantly keep trying to raise it from the deads. Thanks!

On mtk devices a preloader is independently installed, it should be almost impossible to destroy, I owned a x5 pro and had best success to flash it with sp flash by taking out the battery, press flash button and plug it in...
The second huge issue I see is when you used the specific flash tool format option you very, very likely killed the nvram partition which contained the imei, so you'll have to fix this too by generating a new one and using mtk engineer mode which is well described and to find on Google..
But let's go step by step. Check without battery, or if it's a non replaceable you'll need find the reset button..

i have tried before without battery and i tried just now but nothing. Its very weird it was detected before and now no in same and another machine. I am pretty confused and stressed. Hope i didnt do any physical damage.. :crying:. THANKS!

starting to get pretty stressed omg! and is there a difference between MT6737M and MT6737?

i came to the point im starting to lose my mind... tried everything i could, i have 5 days left to repair this phone and i dont wanna pay 85 euros for this. SP Flash Tools wont detect the phone. Tried almost 5 different scatter files,2 different PCs and different mtk drivers. Im losing my mind already

UPDATE: I almost fixed it! I had flashed wrong preloader so phone wasn't recognized by SP Flash Tool. I fixed preloaded with a little trick from here: link. After that i flashed stock rom downloaded from doogee.cc but phone will not boot resulting in a total black screen. When i hot Power + Vol Up it takes me to another screen:
Select Boot Mode:
Recovery
Bootloader
Normal
Doesn't matter which boot mode i choose i just get a total black screen which means i get nothing. Idk what is happening! Any further help would be appreciated! I constantly try to bring it back working with little success and small improvements.

Last UPDATE: FIXED my phone had no juice left inside so couldnt complete boot proccess. Now its all good running Btw someone must pin this META trick link i send on my previous post cause im sure more people out there have preloader issues!!! Thank you everyone!!
