NV ram error. Imei null

[LegendTDD]

The tittle in the thread is about IMEI lost and NVRAM issue related with. What do you want to do onto your device right now? Unlock it?, Which method are you using?

I have the same problem as you, I gave it format all+download and killed the nvram partition of our devices, what I want to know is how to load TWRP into the system to be able to do the procedure they did in the forum

can you link that thread, i haven't found any thread with imei solution,
i did once used chameleon phone apk to write fake imei with root, but that fix did not work, (upon reset, imei was again gone)
also it only worked on low level androids, doesn't work android 11,12,13

Chameleon didn't work for me, though. This is the link, I didn't try it my self, because I sold the device almost a year ago https://forum.xda-developers.com/t/hard-bricked-realme-7.4224115/post-88043143

Okay so I tried that method, it actually does overwrite the imei, but it is only a temporary fix as It uses magisk module to fake it..

My sim card still didn't work after imei overwrite, maybe because imeiSV is still unknown..

Same here, I don't trust much, that this method really works, or survive within reboots, or factory resetting.
And the baseband is good?

Hi people, I was for hours investigating the partitions of my RMX2020 and I discovered that with writing in the android file scatter, find the name of the partition and put TRUE, I could enable it to recover the bootloader, here I leave the zip with the modified android_file_scatter, also to solve the problem of nvram warning

 

[LegendTDD]

If you do not have the files that appear in the zip just search (* phone model * _dump file) and you're done and change the values from false to true of your model's scattered file

 

[LegendTDD]

Soon I will send the tutorial to do it without error in the sp flash tool

Yup the baseband version is still good.

Already tried that, doesn't work, the baseband version goes null after flashing with modified scatter and those listed partions.

i am not sure but i feel with the SN tool, the IMEI could be written again if we have valid database MD1-DB and AP - DB file which is not available for MT6785. SN tool help write with dual sim But it requires Original IMEI number to write again.

What about mtk 6768, ihave redmi note 11 4G stucked in recovry and NV DATA CURREPTED, if ther is solution helpe me, and thenks.

Wrong, and how did you recover the baseband of the device?

You should look for the nv_data file of your phone and with the sp flash tool you should flash_ that is my idea that I can raise but investigate better because I do not own a phone xiaomi

I have tried what you are suggesting, and it leads to no imei repair and baseband unknown as well, I tried my device specific backup,
Though it doesn't mean that it would not work for you, you can give it a try, these devices are unpredictable

By deleting nvram folder in twrp

Man I have tried to place the TWRP or PBRP on the recovery partition. Img in the sp flash tool and I continue in the recovery stock, explain me in detail how I do

 

[SubwayChamp]

In my long shots trying to sort out things, I found that nvdata, either a new one, or from a back-up don't have to be flashed, they have to be recreated/populated at every reboot, in case you format it., so you can try the guide without this partition.

Format NVdata partition, using mtk-cleint, then reboot.

Flash RUI1 first, then with unlocked bootloader, flash twrp v3.5.2 and modified vbmeta.img with sp flash to get the recovery to boot successfully.

Then why the imei is not populated like other information like baseband,

I was on the edge of writing imei by modem meta tool ,but when I use the built-in hex editor in modem meta, after editing the nvram partion upon saving,the whole application crashes..

They're different, IMEI is unique for every device, and it is hard coded, once is "lost", it can't be recover using simply software, it needs pure hardware, to be rewritten at a very low level. NVdata is just one of the partition related to the baseband, not directly related to the IMEI.

This is the reason why, you can´t...

When I tried, it didn't crash, simply it got to 99%, and finished with no success.

Okay, but why can't I use my sim like everyone else, I have my baseband working, I just wanna use my phone with sim card in peace now,
