So my friend gave me a lenovo tablet to fix. The problem was he changed sim card and tablet gone bootlooping. I flashed tabled using sp flash using format all and flash because that was only option working and i found that i erased IMEI And Serial number too. I fixed them using SN writer imei fixed serial number still shows as 00000000 (does that affect device function? ). But device still says there is no sim factorymode says both sims are missing (tried different sim cards too). What is probable cause of this malfunction?
Try factory reset
I suggest you to perform “Factory Data Reset”

Hello,
My phone: GSMART Roma R2 (Rooted)
I know there are a lot of threads how to restore IMEI but none of them worked when I dial up *#06#, it shows message with two lines containing "null".
I was using MIUI rom for a while and suddenly after I rebooted phone SIM was no longer recognized (before reboot I was playing with SWAP couldn't make it work so I uninstalled BusyBox (could that cause the issue?))
I already tried:
Engineering Mode: Displays "AT command is failed to send"
Terminal Emulator: Doesn't work
MAUI 3G: Flashing new IMEI changed nothing.
MTK Droid Tool - Changing IMEI did nothing.
SN Writer: Writing new IMEI changed nothing BUT when I choosed to read IMEI it successfully displayed both IMEI in the textbox. (So it looks like the IMEI actually is registered on the phone but phone doesn't seem to use it)
Manually writing MP0B_001 to NVRAM: Nothing changed.
I have used backup in CWM recovery to stock ROM, didn't work, then I did factory reset, didn't work, flashed back the stock recovery and installed update from Gigabyte site, didn't work. So basicly now my phone has stock rom, stock recovery, factory reseted and is rooted.
Thank you very much for any answers because I just fell hopeless about fixing my phone
Hi there,
I see you already posted new thread in the right place: [Q] IMEI null and SIM not recognized, nothing works
Please wait an answer there.
Thanks, thread closed.
Heya!
I'm using Lenovo A369i. I've flashed the phone a few times before but gotten myself into quite a trouble. I've accidentally plugged out the USB cable when I was flashing the phone the first time and I totally forgot to backup the IMEI number. So, it got a little bit messed up. It didn't turn on the first time. After few flashes in attempt to recover the damn phone, I finally got it on but it can't read my SIM card. It says "Invalid IMEI". I did try to fix it by replacing the MPB_001 thingy and by using the MTK Droid Tools (I didn't remember which one worked) but only managed to recover one IMEI number. Used the phone when it was recovered for about a week and did a format on the phone. After the format, I get the "Invalid IMEI" message again. Flashed the phone once again using the same stock ROM (v111) and afterwards I got a "No service" message instead of the "Invalid IMEI".
Any clue on fixing this one ? I need this ASAP. Tried to search around for answers but only managed to know that I need to change the radio IC but I dunno how to do that.
P.S: My phone stil; works just that it can't read my sim cards (dual-sim)
Currently on my ASUS Zenfone C
This problem raised When I flashed my lenovo s850 with custom rom when the flashing is done it worked but when I inserted my sims it showed me invalid imei then I typed *#06# it showed me invalid imei, ihav googled it & fixed my WiFi nvram error & successful with imei.zip method and pasted my imei numbers but same problem arises that no service when I inserted my sim & serial number also gone, it is showing sn:0000000, I have even showed in lenovo service center but they said it will take up to 20-30 days to return from factory.. Any suggestions to solve my problem?
Thank you.
