Hello people, I have a rather peculiar issue with my SII
I have had this issue for some time now and really doesnt bother me that much, its just annoying. And its just now that I have bothered writing a post about it.
If Ive run out of battery, I plug my phone into the charger, turn it on while its charging, I get no service, not prompted to input PIN and get the Uknown IMEI\baseband version. But if I let it charge a couple of minutes, unplug the charger and turn it on, everything works fine. Whats going on here?
I think this problem occured after installing one of bmarko's MIUI roms. I have since full wiped and restored stock rom. Upgraded two new official samsung roms as they have been released, currently running XWKI8 unrooted completely stock and the issue still persist.
I have searched around and there are similar cases out there but not really any clear solutions. Theres even a post over at cyanogenmods forum site, but no replies.
As said earlier its not really a big issue for me, not expecting a immediate solution but I would really like to understand the problem if someone has the information since I dont have the technical competence to understand it myself. I obviously havent corrupted or lost anything in my efs folder since its working without the charger, or? Could there be remains of a bug from another rom still in the system causing this?
Any replies would be appreciated, thanks.
Same Problem
Hey FlipTrick,
I got exactly the same problem. Dont remember how it happened exactly, but do remember I didn't do anything exotic. Can't display my IMEI, unknown baseband version and no prompt for my PIN.
I Tried several things:
- Reflashed the advised codeworx kernel using odin.
- ReInstalled CM 7.1 and tried nightly version.
- Reflashed different RADIO ROMS from XDA (goo.gl/TjoaM)
Nothing worked. Does anyone know what the problem might be? Or know what I could try next?
Greetings,
Xianduras
I had this problem once when I used a jig to reset the flash counter. Given the modem (and the IMEI) wasn't showing up in the phone details, I reflashed the modem which fixed it.
Occasionally after a reboot my modem/IMEI details take around 20-30 seconds to appear, but they've never not turned up/left me without service apart from that one occasion.
problem gone?!
Problem seems to be gone, noticed it after flashing Hydrog3n rom. Cant say if thats the solution though, havent tested it for awhile and i've flashed alot of roms
Hi everybody, I decided to post my problem here, after not being able to find a solution on my own.
I'm experiencing the same issue as mentioned in some other threads: [1] [2] I have the drain since I wiped my EFS partition, because a corrupted twrp backup (it was a bug in a certain version that it made faulty backups) messed it up, and it wouldn't boot. So I found a solution to wipe it, but I have lost my IMEI. I didn't really notice it, because the phone was working fine, but recently I noticed that it shows "0" for both of my IMEI numbers. Also, I switched to oreo immediately after wiping the partition, initially I made the full backup just in case I had to go back to nougat. So first I thought that the problem is caused by the early oreo builds. But I have tried several nougat builds too, even miui, but I got the same issue, standby battery drain, and no IMEI, even after installing the fastboot rom of miui. Yesterday I thought that they may have something to do with each other, so I decided to try to restore the EFS, and the IMEI. I've followed some guides here on xda and also on miui forums, and after restoring the QCN file for my model (global version) and writing IMEI with the Qualcomm imei writer tool, I succeeded . I got my IMEIs back, and I hoped that it would solve the battery drain too. But today after letting it in idle, the battery drain is the same. I would rule out any ROM specific issue, because it happens on miui too, and every rom I have tried. Also I don't think it's connected to any apps, because I have tested roms also without restoring anything, I haven't even flashed gapps, and the idle battery drain was still there. I only managed to "solve" it one way: changing preferred network type to any of the options, without LTE. If the phone is connected to HSPA+/3G, (without mobile data, just the service) I can get it to last 2 days, and it's the same if I have it in airplane mode, the drain is gone. That's why I also think that it's not a hardware issue. I could use my phone without LTE, we don't even have VoLTE here, so it's not mandatory, but I would like to solve this problem If I have already spent that many hours figuring out what the solution could be. It's also important to mention that even if connected to LTE (phone service) kernel adiutor shows that when the phone is in idle, the CPU goes to deep sleep and not awake. Now I'm reaching out to you guys, could you please help me? Thank you in advance!

Many times, this problem is band specific. Since every country uses a different megahertz band for their LTE service, but in this case you said there wasnt any fault before. Have you tried flashing any custom kernel like francokernel?
Yes I have tried other kernels too and it didn't solve the problem, but I didn't try francokernel on the official rr oreo build yet, I'll give it a try, thanks
I also have to add that whenever I'm connected to LTE (service, not data), the signal is fluctuating heavily. If I switch to maximum HSPA+ preferred network type, the signal becomes stable again. Maybe I should try different firmware zips, idk ?
Okay, so I tried flashing the latest francokernel (r4), have been using it for 2 days, and I don't really notice any big difference in terms of battery life. I also switched the "preferred network type" option to include LTE too, but the battery started to drain immediately. Yesterday I also found a guide (on 4PDA, as I'm trying to find a solution really hard) about flashing a QCN with the qpst tool, to unlock some LTE bands and then enable carrier aggravation(?). I just completed the whole process hoping that it would solve my issue too, but after I enabled LTE again, the battery drain came back... I can't really come up with another thing now, but I'll keep searching for it.
Could anyone please share a full (without apps and data of course) backup from TWRP to see if I can restore my EFS partition successfully? Maybe it would solve my problem as I think it is related to some sorts of modem things, and as I have explained it may be a low-level problem.
Thank you in advance!
I took the time to save and search through the logs of my device, I'll attach it to the reply. This is a log taken from the phone as it was in "safe mode", just to exclude all the unnecessary logs from third-party apps, as I experienced that they don't influence the draining of my battery. As I observed, interesting parts are around line 2365 and 4494 from point of view of the phone service, SIM card, and things like that. Also, it's another interesting thing that until the 184th line, the date is way back in november, and as I looked back, it is 4 days before I wiped my EFS partition, because the phone didn't boot then. I don't know if it is connected to my issue somehow, I just noticed it. After that, until the 1886th line, the date is 2-24, when I flashed installed my current rom, and it may be a bug with the rom itself that the date switches back to the initial installation's time, it may not have anything in connection with my main issue. I would be very thankful if someone else could get something valuable out of it. Also, an EFS backup from TWRP may solve my issue... Thank you in advance!
Hey,
Any solution for this issue ? My case is the same with Lenovo z6 pro.
After accidentally erasing my imei, and flashing it back I have idle drain.
Thx
Hope some one will replay to this 'old' thread.

Hello, sorry for replying so late.
I was provided a solution by @evil-god , he sent me a "healthy" qcn, I only had to change my IMEI to my original one using an IMEI writer, and then restore the qcn file with QPST.
Since -as far as I know-, this is a device and hardware specific file, I don't think one should try it on other devices, but it should work if you have the same model.
As the original qcn (sent by "evil-god" as written above) contains his device's IMEI, I won't share it without his agreement, but hopefully he'll see this post and reply with either his agreement or the file itself.
