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

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%

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.

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.

Never mind... I eventually found LordArcadius method here- https://forum.xda-developers.com/android/help/guide-how-to-fix-unknown-baseband-t3096927
And it is so simple working method that solved this IMEI problem.
Thanks.
Hi,
I just received my phone today and somehow I managed to brick it. I don't know how this happened as I was only trying to fix a common issue I was having with my google play store ("download pending"). I didn't uninstall anything as I didn't even root my phone. I just disabled some apps like the browser and now im stuck at the zuk logo boot page. I got into the bootloader page and it's asking me for an update.zip file. can anyone please help with this?
thanks
well, at least you can still enter the bootloader page, which means the phone is still alive. Which zuk do you have? Did you try reboot? How many times?
hi thanks for the reply. i tried rebooting more than ten times for sure and i am sure i didn't disable any important apps. My model is the Z2. The model number is Z2131 on the box.
I also tried flashing the phone with a new rom as per instructions on another thread but its only showing no port available and when it sometimes shows something its not qualcomm snapdragon as it said in the thread.
Hi all here is my dilemma concerning my personal DD, the phone was bought new in 2015-6 brand new and is currently on Android 7.0! The phone is in my opinion still very relevant and can be made even more so (if) I can update the whole firmware to the recent Note10 UI as seen elsewhere??
The trouble that I have experienced is trying to install TWRP via Odin? What happens, it recognises the file to be used, I set the parameters and start! It moves reasonable quickly then suddenly stops - No errors on the Pc/Odin page BUT the phone moves from the download mode in English to Chinese with Warning triangle and remains there until I reboot phone which starts up as normal??
I cannot get past this, and do Not know why the Change to Chinese that I do Not read or understand, so I have a few Pics but the 2 that I think are telling I will add if possible?
I found something in an overall search via the net, but this was the only one and this though Unclear in it self did Not assist me! Would I be correct in saying that this may be unique in that neither pictures or any where as this error arose hence why my possible struggles? Please can someone help in Solving this puzzle thank you.
Hi all.
I have an unbranded multimedia device installed in my car.
I know its cheep and old (OS is 4.1.1)
the only thing that can help identify is that on startup it says 'powered by Uzeb'
my problem is that the device is locked and no apps are allowed to be installed
I would like to root it so ill be able to install a newer version and if not than some apps.
problem is I can not find the option to Factory reset.
I am pretty sure that this option is gone or at list hidden from end users.
the company that installed it at first place demands an extra payment to unlock it back.
so Im trying to do it on my own.
For some reason I can't attach a photo
in About option,
there is a Uboot version - v00.01.13
Appreciate any sugestions.
no apps are allowed to be installed

Android Auto doesn't work that way - apps get installed on your phone, not on the head unit.
so what am I missing here ?
Its a touch screen mounted inside my car.
it runs on old version android and blocked to end users
who wants to update the OS by themselves or to install different apps (or even update the existing ones)
So this is not Android auto and perhaps im not at the right forum
any suggestions on what else can I do ?
Hello everyone, I am not a developer and don't really understand much of the ROM ROOT world and similar.. But I have a huge problem with my Mi 8. After the updating to MIUI 12.05.1 I could no longer open the Google play store, it kept crashing as son as I tapped on the icon, for that reason I uninstalled it and then I had to download the apk directly from the browse. But even after i reinstalled it, it kept on crashing, not working. I also have google maps and gmail on the phone, which I have not unistalled but I cannot sign in them nor add google account either in youtube or in the phone.
I currently live in Italy but I bought this phone in 2018 in China, so it's the chinese version, this is what makes it even more difficult to understand how to repair it.
I don't know how to solve this problem..
If there's anyone that had the same experience or anyone that has any idea on how to solve this problem please help me, I'd be very grateful. Thank you very much
Are you sure you installed the right version for your phone?
I think the latest version is 12.02. At least that's the version I have...
Did you solve your problem in the meantime?
just wipe, format entire device and reflash with global rom (choose fastboot methods)..

I didn't understand much of what you said.. I'm a complete beginner when it comes to this.
How should I do it? is it safe to do? Could you please explain in a bit more detail (for dummies like me @[email protected]) thank you very much
