Invalid IMEI, no sim, please help :(

Hi guys, I got a big big problem with my K3 Note, I think I went too far with wiping partitions before installing a new rom, here are the folders I wiped:
data, cache, system, protect_f, protect_s, dalvik cache.​
After reboot my phone worked just fine but it didn't see the simcard, I thought it's the OS issue and wiped and flashed several times more.
Now when I got into the issue I noticed *#06# returns "invalid imei", after a little bit research I found out it's a common issue with MTK phones and found multiple possibilities for solving the problem, none of which worked for me though, for no known reason ;( What I've tried so far is: chamelephon app, MTK Engineer mode commands, flashable ZIP with the IMEIs, writing it with SN write tool and another program named something like Mauri? if I remember correctly, all done on the stock rom flashed with flashtool, now I'm retrying all of above on a custom rom.
I read somewhere that missing basebands can be an issue for MTK engineer mode, but I couldn't find any more info on the topic
I don't know if it is connected but the stock rom worked much worse than I remember when I first got the phone, it freezes completely(doesn't react to power button, keeps the led light after unconnected from charger, completely no response, I have to take out the battery each time) about once every 3-5minutes.
Another thing is, does anybody have any idea what the protect_f and _s folders are? I think I shouldn't have wiped them...
Any help would be much appriciated, I don't need another bricked phone... ;(

can you access bootloader mode and reflash with flashtools? i assume you dont have a backup? as far as i know the first partitition is responsible for the connection through USB so as far as i know if im not wrong you could reflash these partitions. dont know much however over these mtk devices
---------- Post added at 11:46 PM ---------- Previous post was at 11:41 PM ----------
freezes and shutdowns, even in lenovo stock recovery are a common problem i have found out. this has nothing to do with partitions in this case however dont know if this can be valid in your case. however in my example it is a fault within some lenovo stock roms. hope anyone can help you with more information

I do can flash with flashtool, at least thats how I flashed the stock rom, but I dont have a backup. Is it possible to use my IMEI with a different backup?

with my limited knowledge over the subject. preloader is the recovery since you can get a connection, what is safe to try without tinkering to much is flashing the latest vibe 3.0 45 dev rom over at needrom.com, since this rom also affects other partitions. once you have done this completely wipe every partition manually sometimes in TWRP i have seen some partitions dont function fully until you change partition format from ext4 to f2fs and back to ext4 and then wipe and repair in my case it has been for example.
as for the IMEI i havent been handson with these subjects so it is better for someone else to inform. This tip can be tried without risk as hopefully the dev rom will restore partitioning, at least it is worth a try.

i cant answer your question on the IMEIs since lack of experience on the subject. however what i can say is that freezing and shutdown in stock k3 notes is a common problem and it is not hardware related. Does this problem also occur with a custom rom such as AOSP

Just to give you my total view on fixing the issue hopefully what i would try is:
1. flashing twrp
2.through twrp flashing the latest dev rom
3.reformatting every partition (meaning cache,dalvik cache,system,data,internal storage)
4.flashing a rom such as androim through twrp
5.trying the lost IMEI patch, input your info
6.to be sure use xposed framework uninstaller cause of performance gains
7.eventually using some tweaks such as l speed to get your device optimal
If the issue of freezing and random shutdown was of the same nature it should be solved 100%

http://forum.xda-developers.com/and...ed-thread-lenovo-k3-note-k50-t3158522/page117 latest dev rom

Damn, the official roms are unusable, they keep crashing after like 2-3mins.
Thanks for the link to the rom! I was looking for it for some time. Well, it installed without further complications, now I just need to find out how to restore my IMEIs... Hope at least one of all the methods will work this time.

I've found the answer to all my problems. I need a backup from another K3 Note, manually overwrite the IMEIs with mine and voila, it's supposed to work, at least works on other MTK phones.
If anybody here is willing to help me out please contact me, if you're afraid of sharing your IMEI numbers I can send you mine with an instruction on how to overwrite them, you could save me my phone and some money.

invalid imei number problem solved
1. flash new stock rom in ur device.
2. now you have two options
a. you can update your device. ( do all the updates of lollipop but don't upgrade it to marshmallow )
b. you can use the current rom that you have got after flashing.
3. root your device using kingroot app that you can easily find on net.
4. after rooting install chamelephon app on your device from play store.
5. remove the battery and note down the imei numbers written on back of the device.
6. plugin the battery and switch on your device.
7. open chamelephon app.
8. enter the imei numbers.
9. Hit apply new imei option.
10. wait for 1 min.
11. switch off your phone and then switch it on.
12. your sims are ready to work.....
Note ( do not update the device to marshmallow as kingroot app is not able to root lenovo vib marshmallow updated devices.)

hi himansu,
can you tell me which stock rom you use.
i try already your solution, but still not working for my phone.

Please help
Dear Nechoya,
I got the exact same problem as I followed your footsteps of wiping too much.
Now my K3 note has NO IMEI and sim says NO SIM CARD INSERTED. I have tried all the usual methods mentioned on various threads but nothing is working for me. Can you please clarify what worked for you with some details. I am not a pro and anything from your side or any of the members reading it will be of immense help.
Thank you.
PS I Dont have any kind of backup

Try lord Arcadius' method.

I used SP flash tool (format whole flash button). now the phone is hard bricked. not taking charge, didn't power on and it's like a dead phone. For unbricking, the stock rom is needed.

Few things your device doesn't have after formatting whole flash.
no preloader in bootloader partition.
no partition table exist in this state.
no nvram/nvdata means no IMEI, no working network, no working wifi etc etc.
one more question !
is it detected by pc or not ?
my view on stock rom requirement is pretty useless. The reason behind this, if someone give you the whole firmware package (it is possible to extract the whole firmware) but they won't give you their device nvram data. After recovering, it has no radio signal merely a music player and nothing else.
It is better to sent your device to the service center.
I also unable to restore firmware through Sp flash tool. The whole firmware dumped with miracle tool and only miracle tool flashable but it gives some strange error "Error 1: no 5A" after this error firmware installation stopped. Another way i found is to flash whole firmware through fastboot tool. Your device must have bootloader in bootloader partition and partition table along with this nvram data required too.
Hope this helps !

Why dont you flash TWRP followed by ROM of any choice ?
NV normally contained in EFS partition, which can be backed up and flash from TWRP and QPST.

This is absolutely not a issue, that requires using Qpst
You simply need to wipe data and follow the on screen prompts. (You will lose all data on your phone.) However the phone will work again.

Sorry that you are having these issues, But my comment was based on the photo that was posted on the OP. Typically formatting is the resolution. If you no longer have that screen available, you should contact an authorised repair center to fix it for you.
Otherwise If the phone is bound to your account, you could try what is listed here: https://www.mobilerdx.com/2019/02/xiaomi-mi-8-test-point-boot-xiaomi-mi-8-into-edl-9008-mode.html
Scams or Actual Fixes?
I have recently read about supposed hacks that according to a couple of Chinese BBS sites, has worked for some that require buying a specialised Jtag programming tool which cost about $60, that you use along with altered versions of following files: prog_emmc_firehose_8909.mbn.elf, mi8 persist image, rawprogram0, frp and a patch file. All of which that can all be obtained from here: https://romprovider.com/2019/09/mi-account-remove-xiaomi/ ( UMT Download)
Supposedly Chimera is another option: https://chimeratool.com/en/docs Again I have not used any of these tools with the mi8, I am merely sharing what I read about recently.
By the time you have spent the money acquiring the tools, it seems that you are better off just mailing the phone off to be repaired by an official repair center. Here is a web page that provides a list of official repair centers : https://www.pinoytechnoguide.com/2014/06/xiaomi-service-centers.html
Good Luck and try anything mentioned above at your own risk.
Edit: Have you tried the Flashall.bat method?
That should work since you are seeing the com port.

root cause of your issue is that you play with wrong qcn and messed up the nv,
wince you cant plugged to qpst, you need someone to make EFS backup for you torestore from twrp

You can restore phones imei if your bootloader is unlocked but only 2nd sim slot will work

How can I do this? Can you help me please?

Dear All,
While trying to install MIUI 12 Beta , I Lost my IMEI
Installed ENG Firmware which allowed my to edit the IMEI using the Maui META ver 10.1816.0.01 but due to corrupted NV Data the phone isn't booting
Anyone can backup and share the NV Data file ?! i found one online but unfortunately it has a password and can't unrar it.

You need backup EFS and Modem via TWRP first(better with OrangeFox). After you need Magisk first and some manipulation with QCN file via QPST. I will write it later

Maui Meta is for MTK cpu phones. You need QPST

Note 8 Pro is MTK Device

Mi9T Pro no IMEI, no sim card signal.

Heyo!
My Mi9T after updating to miui 12 stopped getting sim card signal and a local repair shop said it's because the phone has no IMEI number!????
What should i do now? How to resolve this issue?

Flash persist.img in recovery if you have a backup....

3 STEPS for you :
1. well , if you don't have efs/modemst's backups to restore, ITS NOT LOOKING GOOD.
2. next logical step try a fastboot rom flash , if IMEI is not restored , ITS BAD.
3. your device needs an IMEI repair , better done by a proffessional (he uses some hardware to repair the imei).
Best of luck to you

You cannot find them, they are specific to your phone , they have info on your IMEI numbers and device specific IDs ,so flashing other people's files would mess up your phone even more.
DO not flash FASTBOOT Image unless you backup your "persist" partition as you would lose other important stuff that cannot be recovered.
You have to root your phone , backup your persist partition , then flash Fastboot ROM to see if your IMEIs are restored.
If not , then IMEI repair is the way to go , just find a good repair shop and they will do it for you.
