Missing IMEI & Bootloop - Galaxy S II Q&A, Help & Troubleshooting

I have been a user of Neat Rom Lite and Rootbox. I have been using Rootbox recently.
By updating from 7-16 Nightly to 7-19 Nightly (dirty flash) , I have lost my IMEI number and consequently cellular connection. Using EFS Pro, I've been able to recover my IMEI. After a day, I had to reboot my device randomly and IMEI went missing again!!
This time, I have used Rom Nuke and flashed NeatRom Lite and found the IMEI still missing. I've used EFS Pro again and now my s2 is in a bootloop. It doesn't get past the Samsung Logo!!
Need Help!!
Sry if posting in the wrong thread! :crying::crying:

Lost IMEI?? Is it showing zeroes or something wrong...?? I had lost IMEI once after installing some RIL app.. But after a fresh reinstall of OEM firmware i got it back... Try reinstalling the stock unrooted firmware.!!

fix bootloop by going in recovery and wiping data, cache, dalvik cache

Don't dirty flash. To risky and not recommend mate.

IMEI lost and stuck in Bootloop with stock

Hello,
Recently, I was having problems with my cache partition being corrupt as I could not install apps from the play store. To fix this, I flashed stock rom S5830i_XXLI1_ODDLI1_DDLI1. After flashing via odin, I got stuck in a bootloop and had to flash cyanogenmod RC 3 with the CM kernel after which the phone started working. Since then I have lost my IMEI number. I tried flashing S5830i_XXMC1_ODDLK1_DDMC1 but my phone is again stuck in bootloop? I think the kernel is the reason why I lost my IMEI, so I dont want to flash it again. Is there anyway I can get my phone to working conditions?
I have tried the Hex workshop method which hasn't yet worked for me.
In CM 7 Rom,IMEI bug is not solve. Search in xda you will get the information about how to restore IMEI or see CM7.2 Rom's thread and comments.

Flash a stock Rom again and boot into stock recovery(power+home+volume up).Now wipe data/factory reset, wipe cache and Reboot.

I9300 battery died now bootloops

Hi guys little intro
Samsung galaxy S3 I9300 International
Running
TWRP recovery
Slimbean android 4.3
Basically what happened is the battery died on the phone so i swapped it out for a charged one and the device just bootloops on the slimbean logo. I then went into recovery to restore from a backup and after the restore it said "This device does not appear to be rooted would you like to install supersu." <-- alarm bells?? so i click yes, and now it doesnt even boot up the slimbean logo it just sits at the samsung one.
I have tried
Re rooting using cfroot
Reinstalling recovery
Reinstalling the rom
Restoring to a backup.
Nothing is working? is it possible for phones to throw wobblys and unroot themselves? which would explain why i cant load a custom rom?
Whats worse i cannot for the life of me figure out why just pulling the battery would result in a bootloop?

help pleaseeee
An instant shut down will usually result in data corruption, first try clear cache and dalvik, next a mega wipe script.
If that also fails then probably best to flash a stock rom using odin on your pc. You might need your efs backup if that partition was damaged.
Managed to resolve the issue by first re rooting with cfroot then installing twrp then reflashing the ROM, unfortunately my micro SD card got corrupted over 30gb of music and data gone, not impressed, also lost my nandroid backups and my titanium backups

boot loop even after doing everything. :( HELP

hi. i tried to flash avatar on my rooted i9300 and i got into boot loop so i some how came out of that by flashing stock firmware via odin. but i could not get mobile network, so i tried to restore efs folder by EFS professional software. that is where again i got in to BOOT LOOP. (like never ending). since i had already experience this problem so i started with wiping data/ factory reset, wipe cache, use odin to flash stock firmware/checkrom/rescue rom. as far as i could read every possible thing, i tried to follow but all i am stuck with is a never ending boot loop which takes me up to asking Google account details then goes back to reboot and i9300 logo and same cycle.
one more thing i have removed sim card and sd card, but still in rebooting phase as i mentioned i can go up to Google account details. i can see network signal on top even if i have removed my sim card. Is there anyway out..
Wiping data factory reset does not wipe previous system rom only reset's it you need to wipe your system but make sure you install a rom soon has you have done it.I suggest installing philz recovery it as got a built in wipe before installing a rom feature.Follow this guide http://forum.xda-developers.com/showthread.php?t=1911726 look at Wiping & Flashing - Cleaner Flashing Method :good:
You can also use this http://forum.xda-developers.com/showthread.php?t=1832326 but be very careful make sure you have a rom ready to install on your sd card

Copy the ROM you want to use to your external SD card, also download the matching GApps.
Do a full reset of the phone. Go into Recover (most recent OrangeFox) and format DATA partition (type YES) and do a full wipe (DATA, System, Cache and Dalvik).
All your is now completely clean. Install your ROM, install GApps, restart your phone and be happy

The last option is to flash original Xiaomi ROM with EDL mode. Do that and see what's working and what not. Then we can continue
Did brother.
I already did that brother.. Problem exists.. I can share a log file..

This is what is says when I click summary.
Your issues were mostly caused by error in EFS partition. EFS stand for Encrypted File System, and it responsible for the modem, wifi, mobile data connection, and your IMEI. Once EFS error, your device won't be able to read IMEI nor give wifi and mobile data connections.
My advice is try to clean flashed Mido's latest official MIUI ROM (MIUI 11), which contain the right EFS for your device. Do not attempt to flash other ROM first, since that wouldn't succeed if your EFS still broken.
It is because the significance of EFS why official TWRP also offer to backup it in it's feature.
