[Q] Y300 IMEI bricked, searched everywhere, help please - Android Q&A, Help & Troubleshooting

I was installing different custom roms without problems and one day I decided to try Firefox Rom out, I did that and since that day I never got any signals from my network, I did a check on my IMEI it was blank(I have attached a screenshot)
I've tried using CM roms, original stock rom, even Gingerbread just incase :/
I've searched everywhere and found out about 2 softwares that might do the thing .. 1. SigmaKey 2. zZ Huawei Advanced tool
I did not make any backups before so im kinda doomed :/ I still have the IMEI written on the back on the phone though
Problems with SigmaKey:
It starts, says No Smart Card Reader Found.
It says Connect Dongle/Box
Problems with zZ Huawei Advanced tool:
It doesn't start, I've tried 3 different versions with every window's compatiblity set.

Flash modem files from original stock , extract the modem files and flash it through recovery or adb.

Go into the zip file, there will be a folder called modem or a file, extract it, make a flashable zip, tutorials can be found on the forum, flash, wipe cache, davlik, reboot into system.

are you sure thats how to do it? fyi i have flashed cm roms again and again and theyre all working but the imei isnt there .. if what youre saying is the way then flashing the complete rom will automatically flash the modem files right? and if so then i shoud've gotten the imei back which is not true in my case
i was searching for IMEI repair stuff, isn't this what i should be looking for?

Your IMEI is having problems because your modem files are either corrupt or a non compatible modem file has been flashed, Flashing the stock modem files will fix this problem.

If it was CWM compatible, then it wasn't the full stock firmware and not likely to flash the modem with it unless specifically stated by the developer of the rom.
So, flash the modem or full official firmware. If that doesn't work, then it's going to be even more of a headache, I'd imagine.

Probably easier to just flash official firmware and redo steps for root/recovery/rom.

man, I cannot find modem files :/ and I need a little help making a flashable file :/ I'm sorry for being sucha noob
Fist off, I downloaded the official file from the huawei's server which is update.APP and not a zip that I can just open and extract the modem files(if there are any)
Secondly, the other roms that I already have CM, etc .. they are all of ZIP format and after I searched inside them I could not find any modem files man .. is there any information you can provide?

I'm not as familiar with Huawei, as say, Samsung, but I can't say I've seen modem files only posted for many if any Huawei phones I have looked into. Decompiling the update.app, and figuring out how to grab the modem files and getting them to install to the correct partition might be more of a hassle than it is worth. I think all you have to do is put the update.app in a folder called dload on an external SD card and then boot to Software Update mode to let it do it's thing.

I believe i have already done this in the past, but I'm not quite sure as with all the experimenting its hard to keep track of what experiments have you already done lol .. but alright, I'm gonna put the UPDATE.APP inside the dload folder on the sd card ..
just to confirm, software update mode is the recovery mode right? where there are options to format and factory reset and wipe partitions or update via sd card ??

Follow the link (post 2) I sent you earlier. It has the steps that were pulled from the manual on how to update.
If you have a custom recovery, it might be possible to just make an update zip with the build.prop. You can decompile the update.app with this tool I believe: http://forum.xda-developers.com/showthread.php?t=2315547 to get the unmodded build.prop.

As stated in previous post, cwm flashable rom's don't have the full rom in them, most of the time modem is not included, you need the modem files from stock.
