You need both NVRAM + NVDATA partitions,
or ...

Simple, format both partitions, and use MauiMeta 9.x build,
which doesn't need BPLGUI/APCFG database files,
to restore imei/etc.

Before that - try to reflash device with correct rom package,
which (for A7020a48) can be found - HERE

trying to understand what's happening

Guys
I got this phone with 6.0 row version (international) in it.

I tried to downgrade to lollipop row version --> phone got dead.

I tried to flash Chinese lollipop ROM got from neerdrom which the author claims it has got stock nvram/nvdat , probably a ROW to Chinese conversion ROM ---> the phone got dead.

gave to service center and got 6.0 row version installed in it.

Now I am in confusion that was my k5 note really a international Row version or k52e78. ??!

I got baseband unknown error.

Which ROM to flash??

I dunno how many times SAME thing should be repeated OVER AND OVER again.

everything is explained like 20 or more times before.

* If phone shows no baseband - wrong model / flash file mismatch
* If phone shows baseband, but no imei/imei null, erase nvram+nvdata, repair imei.

Very very simple. For A7020a48 - post #33. All there long time ago.
Probably in some earlier posts too.

There are 3 versions of A7020,

- A7020a48 WITH fingerpring sensor. ROM: A7020a40_S318_161128_ROW

- A7020a48 WithOUT fingerpring sensor. ROM: A7020a40_S318_161128_ROW

archive pass: lenovo-forums.ru

- A7020 China (K52e78).

There are also APDB / ModemDB files in ROM packages, for easy repair
of imei, sn, bt/wifi mac etc.

All before said, still applies, regarding baseband/imei problems.

Flash phone with format all+download with spflash tool v5.1552.00. Power on the phone then u will get ur baseband back.
For imei repair, use SN Writer V1.1632.00 and choose Target Type 'Smart Phone With C2k' witch is only available in this version, in system config check imei in write option, imei checkSum and dual imei in imei option, and check Load Modem DB friom DUT, then choose db file witch come with flash file. Then do repair.

Wifi nvram warning can be repaired with SN Writer just by repairing mac adress (put original mac adress if u know it or annything.

http://download1479.mediafire.com/p0...v1.1632.00.zip



About nvram restoring, only spflash tool v5.1548 is able to restore but nothing change, it seem fake restore.
Other spflash tool version give BROM ERROR : STATUS_SEC_IMG_TYPE_MISMATCH (0xC002002A) or other code.

Note:
- if u flash ur phone with spflash tool v5.1548 u will not get baseband if ur phone is formatted and other version will give error.

True.

Download attache archive, unpack, start SPFT, load scatter.
Press CTRL + ALT + V, go to drop-down menu "Window",
select "Write memory", new tab will appear - "Write memory".

In it, select under "File path" - nvram.bin,
input Begin Address (HEX): 0xd780000
Click "Write memory", connect powered off phone to cable, wait for finish.

Repeat procedure, under "File path", select - nvdata.bin,
input Begin Address (HEX): 0x4bc8000
Click "Write memory", connect powered off phone to cable, wait for finish.

Now you have valid nvram and nvdata.

If you get "Tool DL image" or other message in bottom left/right corner,
simply reflash (from stock rom) ONLY cache.img

post results.

p.s. PAY attention to ADDRESSES, they are different for NVRAM and NVDATA.
Copy/Paste them, thats best way.
