Asus zenfone laser 2 (ze550kl) : Help! Bootloop and imei issue. - Zenfone 2 Laser Q&A, Help & Troubleshooting

ASUS ZENFONE LASER 2 (ZE550KL)
So, I rooted and installed lineage OS, it worked quite well for a month or so, then :
1.) First of all, there was no network detected for both of my sim cards.
2.) On restarting the phone, it stuck in bootloop for 10-15 mins and then started, this time showing no sim card inserted, there was null IMEI when I check it in settings.
Went to twrp, wiped everything except sdcard and usb-otg, installed lineage, everything worked fine. Now, after some days, again the above 2 things happened.
Removed lineage and flashed Resurrection Remix 7.1.2 for the phone. Worked fine for 2 days and again network gone and no sim card with no imei. So, now i know its not a ROM issue.
Every ROM works fine and then randomly deletes IMEI after some time. Can someone suggest anything?
EDIT : I used this guide https://forum.xda-developers.com/ze...50kl-ze551kl-zd551kl-ze600kl-ze601kl-t3333482 . Now I have a stock recovery with no OS installed. Flashed the stock downloaded from ASUS website via "Apply update via MicroSD". Phone stuck in bootloop, sometimes starts showing "Optimizing App 1 of 1", then restarts all over.
Now, I have a phone with stock recovery and which won't start. Desperate for suggestions, anyone help please.

[Q] Soft Bricked handset

Hello,
I've got (had) an SM-G900W8 running the XtreStoLite v2.0 LP BETA5 ROM on the XXU1BOA3 kernel. I installed TWRP 2.7 via Odin, and left the latest modem and bootloader updates I got through KIES3.
At which point I got the chance to sell the handset on Kijiji, provided I could get the stock ROM back on.
I downloaded the latest Odin (3.09) and the correct Firmware for my handset from sam mobile, and factory reset the device. I pulled the battery, let it sit, and tried to flash once I got it back up in download mode, and it wouldn't work.
This isn't too much of a surprise to me, because since I flashed TWRP, Odin hasn't ever worked for me. Regardless of how many times I've tried to flash the modem and/or BL that XtreStoLite asked me to use in their how to thread, it wouldn't work. I was willing to ignore it b/c the ROM worked with the modem and BL it was running.
My problem is that once I tried to reboot, the system hung at the BL animation. I went back into recovery, and tried to move my backups off my external storage (I had 2 back ups that were about 2 or 3 gigs each, too much for the local storage) to the local card and restore (b/c TWRP won't restore from the external card) and the back ups failed.
Now I've got the BL screen, but it won't advance to the animation, and it won't boot to TWRP either.
I tried to restore from KEIS, but it says my device isn't supported by KIES 3 (it is). I could really use a hand here. Every time I try something this gets worse. I'm no pro, but I've had no problem figuring this out on my old HTC handsets.

Bricked phone? Cant flash anything, Odin crashes, Recovery wont install stock firmwar

Bought a 'new" Note 4 and right of the bat, I rooted the phone, flashed a custom rom, followed instructions one by one, last time I did this was 2 years ago. Everything was great, but wasn't able to call or text on a Sprint network, but had LTE/3G data.
I downloaded the stock firmware from SamMobile, cant flash it with Odin, it crashes right away with some error "BEX". So, copying the firmware to my sd card and installing it thru TWRP or PhilzTouch, instantly crashes, says install aborted and when it reboots, the Samsung powered by android is displayed and than keeps re-booting about every 10 seconds.
At this point, I at least want the phone to run stock. But is much harder than I thought it would be. IS there something im missing or not doing right?

Note 3 N9005 wont boot any ROM

HI
My friend need help with his NOTE 3 SM-N9005 LTE
Phone wont boot anymore. It only bootloops. I installed stock rom 2 times with ODIN and still phone stuck on recovery booting and then reboots only.
Then i flashed TWRP with ODIN and cleared everything on phone and wiped then installed MagMa_NX_UX9.7_Premium_XDA ROM
and everything sucess and seems fine, but when comes to boot it only stucks at Note 3 Splash some time and reboots.
I wonder if his partitions are ****ed up or something? ODIN dont show any errors neither.
HE said that this came after some update or something but i dont know if he tells the truth about what really happened
with the phone.
Any way to reparition whole phone and maybe update bootloader or something?
I forgot to mention that he replaced the LCD with new one but could it realy be issue? Because everything works in recovery and i can see Samsung Note splash screen.
I manage to fix it.
I flashed EUR version of STOCK ROM instead of NEE and phone finnaly booted. I dont know what the heck problem was.

SIM Card not usable after flash

Hello Community! I hope I am right here, otherwise please just move this thread to where it belongs to, thanks!
I have a serious problem with my sgs 8 (950F). I flashed newest twrp, magisk, renovate-ice-g95x-r164 and no-verity-opt-encrypt-5.1. Everything worked fine and like a charme. I decided to update to a nightly version (worst decision ever) and before i was able to flash, twrp said: zip file corrupted. So I decided to go back to version 164 via the full backup i´ve made in twrp before. After the restore-process was finished, the device didn´t recognize the sim card anymore. So I tried to go back to stock firmware, which did not work since (after odin says pass) the firmware always stops at 32% and erases everything but the download mode on my phone. So I flashed twrp again, made a full wipe und data format and installed the renovate ice 164 again. After the boot, the sim card is detected and I also have to unlock it with the pin code. The problem is, that i can´t enter the network (Austria/Telering) and also I can´t search for any networks with my sim card, only emergency call is available. I am desperately looking for a solution to solve that problem and since I am no expert when it comes to details in flashing and the connections between hardware and software, i really could need help from experts. My guess is, that something is wrong with the modem. Can this be solved by flashing the mode new via odin? Stock firmware is not able to be flashed on my device, because of the error I mentioned above.
Thanks for you help and time!

Mi a1 bootloop or no sim card detected

Hi recently i have tried to root and install twrp for my mi a1 I had a lot of issues but i finally got twrp installed. Once twrp was installed it was all fine but when i tried to install magisk and root my phone my wifi slider would not go on. So i flashed the stock rom with mi flash this is when the problems began. Any stock rom i tried to flash would just put the phone into a bootloop. There was one rom that i had installed that worked however my sim card was no longer detected. I tried to ota update to 8.1 to see if that would fix the sim card issue but as soon as i updated with ota the phone would start bootlooping again. I then installed twrp again and tried a custom rom instead same issue the phone will just keep bootlooping. Its been a couple days now pretty much non stop trying to fix this phone but nothing i have tried is working and im going to need my phone soon i dont care what rom i have i just need a working phone. All help is greatly appreciated. PS my sim card slot is stuck and wont open so i cant try a different sim card but the sim card was working before i reverted to android 8 stock rom. Thanks guys.
