[Q] Nexus 4 endless Bootloop. Help !! - Nexus 4 Q&A, Help & Troubleshooting
So
I just fixed my broken Screen on my Nexus 4 (i earn money repairing phones), and i got a problem. The Proximity Sensor and Light sensors werent working so i just took them off and tried to boot up again. But my phone isnt booting anymore. It just keeps bootin inside a bootloop. Device was never rooted or unlocked. So i tried resetting but didnt work. Then unlocked the device and flashed a custom recovery and several different roms but didnt work either.
Now i wanted you guys help, if you could tell me if nexus devices dont boot up with missing hardware. Because my experience tells me that almost every smartphone even boot up with mossing hardware like the sensors and things.
Dont know if anyone ever had a problem like this, but i hope you guys can help me.
I dont want to huy a new proxysensor before being sure its about the missing hardware, cause the sensors are like 20 $ and that phone isnt much worth anymore.

I'm having the same problem with my Nexus 4. It just went into bootloop and i've tried flashing these stock roms. The phone turns on normally after flashing these roms but the radio doesn't work. It shows baseband unknown and no imei.
If anyone can help then it would be great.

Did anyone's Nexus 4 fell or got damaged before getting stuck into bootloop?
In one Thread i read that there was some issue with the vibrator in the phone and after removing it and reflashing the phone worked perfectly normal.
I guess my Nexus 4 fell the day before it got stuck into bootloop.
But i don't know how right i am so if anything like this happened then do post it here to let us know.
Has this been resolved??? I have same issue as OP, replaced screen for nexus 4 proximity sensor problem, then tried to fix it and now in bootloop even after unlocking device and flashing android 4.4.4 and 4.3
Could someone try this and post the result here? http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060

Bootloop
same problem
Hey guys i don't know about the bootloop problem but i have changed my screen on my nexus 4 too and i had the proximity problem, i found a fix on the internet you just need to take the little rubber thing on the sensors with two holes and turn it around. I don't know why but it works. Hope this helps at least somebody.
If someone have another nexus 4, please backup EFS folder whit this http://forum.xda-developers.com/nexus-4/general/efs-nexus-4-imei-efs-backup-restore-t2740788, use it, move backup to compiter, open m9kefs1.img with an hex editor, find the place for IMEI code and change it to the original IMEI for not be illegal; maybe can work also from backup of another device that use EFS folder for IMEI.
If work please upload it without your IMEI
Sorry for my bad english

Did lg repair the phone? Sounds like the motherboard was damaged during the screen replacement.

[Q] Network Issues
Greetings all at XDA Developers I am having a very serious problem with my Galaxy Y. My phone keeps on going into Emergency Only mode intermittently. For example it will have signal when I go to bed and then when I wake up it will be on emergency only. It also happens randomly during the day and the only way to rectify the problem is to restart my phone. I did have a custom ROM and that is where it started, I then installed another ROM and the same issue occurred. I then decided to flash my phone to stock firmware (it is still on a custom kernel) yet it is still happening. If anyone could help on this problem it would be greatly appreciated. Thanks

keeps happening to SGY users i dont know why but i conclude this because some of my classmates use the same unit also my 2brothers experience both in stock rom at Custom ROm dont know how or why? we have all different kind of baseband but still it occure for me sometime oh dont know why
blackpanther2209 said: maybe the problem is your sim card but i'm not sure... Click to expand... Click to collapse I thought of that as a possibility. It could be but I doubt it. The SIM is only about a year and a half old. I think it could have been some dodgy configuration with a custom ROM that is still somehow present
R u sure when you flashed stock Rom it was the version you had originally So 2 android phones walk into a bar

No phone calls?
Hey guys, I come here very often and now I'm going to have to open this thread because I've seen absolutely no posts about my problem.. My S6 Edge+ is currently unable to make any calls and I don't know why..:crying: the strange part is that I can still send text messages and use my SIM's mobile data... Another weird thing is that whenever I reboot the phone, my WiFi passwords are forgotten.. Can any one help me? I'm currently running android 6.0.1 and I am considering downgrading it to 5.0.1 to see if it solves the issue...
Still needing help.. No one?? I really need some help since I've tried 4 different roms and modems ano nothing seems to work....
Have you wiped everything and then flashed a stock rom? /CK

Click to collapse Which variant do you have and which MM firmware did you flash? Check your modem, imei, network operator etc and provide that info here. Also wifi password IMO related with Code: ro.securestorage.support=true this line in build.prop. I would suggest you to add this line under 'ADDITIONAL_BUILD_PROPERTIES' in build.prop but assume you havent rooted your device. If have, add it. Powered by Elektrik
I've downgraded to 5.1.1 and it didn't work, I have the international version of the s6 edge plus and now I'm looking for a new ROM to test to see if I can solve it.. I've checked my imei in two different websites and on imei.info it comes clear, but the other site gives me a blacklisted warning, which makes me think since I bought it online second hand... it probably was reported stolen or lost and now it's blocked... which ise rather inconvenient. . If I go to SIM Card Status it says "Not Available" everywhere, but on imei information it says my imei and on IMEISV the value is 01. It's network unlocked and right now I'm about to flash a new ROM, probably stock..
Hello, I have the same problem at boot after I receive the call when making a call nothing remains of numbering you have a solution? thank you cordially guillaume
Hi guys, I know this is a really old thread but I'm here just to say that the problem was with the IMEI, it was blacklisted.. I changed it with a friend and then everything worked fine.. Thanks for you help mates!

E330l - enemy number 1
I've got Galaxy s4,korean model e330l. I've tried to install every rom I could found on the internet (about 10), from official samsung roms to unofficial roms. The phone is in bootloop, on some roms it turns on once on a while and then everything is fine untill next restart after few minutes. It's also getting hot in the area of the back camera. I've got two questions, maybe somebody could help me: 1) is it still possible that is a software issue? What else can I do through Odin? Install Pit files? 2) if I would like to change motherboard can somebody tell if the motherboard from e330s model will be ok with a display of e330l Thank you very much for your help
Doubt it's a software issue. The display should be fine. People have repaired GT-I9505 with GT-I9500 parts and vice versa.
