The story
Hi everyone, thanks for reading me and thanks for your time.
I am stuck with this galaxy S5.
I got a S5 in the past, a beautiful SM-G900F on which I run lineageOS no problem whatsoever.
I bought another S5 from ebay, turns on it's a G900A.
Had problems from the start, the phone seemed to often restart instead of turning off normally, and I had severe battery drain both while on and while turned off. So I went to this section and looked at Root, Roms and other cool stuff and followed the guide to put up a custom ROM.
The problem
The first step, installing the experimental firmware, seemed to work but after reboot no OS would install, instead I got "MODEM CRASH".
So from there, I tried to roll back to stock.
I put on BOF3, which works, but since then I have baseband null and IMEI unknown.
Panicking, I tried to install COI5, but same problem there and also multiple bugs, so I went back to BOF3 and it's all functional, but same baseband/IMEI problem.
I have tried to reset to the oldest stock G900AUCU1ANCE but ODIN fails at the very start. I seem to understand I'm on android 5 and cannot rollback now, somehow.
If anyone has any idea on what I can do realistically.
I have no EFS backup as when I started I didn't know what EFS was.
Thank you all for your help.
I have seen many topics with this problem but I have only been confused more by them so forgive me for posting here.
Bump!
Can anyone help?

Hey everyone, this is my first time posting on a forum, everytime ive had a problem ive been able to find the answer to it. However today seems to be the day ive hit a brick wall. Upgraded a couple of weeks ago to ICS 4.0.4 on my uk galaxy note, and like many other users experienced a few bugs. I took it upon myself to downgrade back to gingerbread. I backed up my galaxy note using Kies before the downgrade. The downgrade went okay, had to wipe all data due to issues but i thought this wouldnt be a problem due to the back up i made. However i have now found that i cannot restore for whatever reason (suspect its because of the different firmware).
I tried to extract the SBU file using SSV card extractor to atleast get my contacts work but i had no luck working it.
Please if anyone can help me? Would upgrading back to ICS 4.0.4 allow me to recover files?
Thanks for your time.
Good day all, first timer posting but have been reading the forms for a while now.
I have a major problem with my galaxy note GT- N7000. I have browed through the forms and have not seen a problem like mine. I really need help with my phone.
Problem:
The phone is rooted with paranoid android rom; current version PA_n7000-3.60. I have been using this for over a year with no problem, when all of a sudden the phone goes into android update screen and ever since been on that screen whatever I do. I never tried to update the rom or anything when this happened, just found it like that. All auto update are turned off.
I have tired installing the rom again using CWM and even tried installing the latest update still the problem persists.
I don’t want to format the phone because I have some very important information I will lose if I do. Cannot back up using CWM, getting error messages, cannot get access to phone via connection to my computer. I am in a jam and really need help with this.
Thanks.
Hi all
I'm running PAC-ROM. So far everything has been fine for months, but sometimes when my device rebooted spontaneously it would be missing its signal. A quick reflash of the ROM usually solved this, but its not working this time.
Today I've found out it's because there's an unknown imei and baseband. I've searched and found a few threads but so far have nothing to work with.
I've got s-off if that helps. M7ul.mcan anyone help me?
Thanks in advance
Hi guys and gals.
I've been flashing roms for years and I've soft bricked my devices dozens of times and have always been able to recover, except this time.
I was running Cyanogen mod 12.1 and all the problems started happening after a nightly update. Basically, the phone got super laggy and eventually started random rebooting. I thought it was a bad flash or something was wrong with the latest update so I did a clean wipe and flashed another rom, same thing happened. Eventually I Odined back to stock and it ran fine for a few days but the problems came back. Now the phone won't even finish boot anymore. I used NAND erase all in odin and and reflashed again, it seems to be better since it wont reboot its self anymore but I can't get past the T-mobile splash screen. Last night I tried reformating the NAND using a PIT file but I kept getting "Secure check fail : PIT". I was starting to thing the problem is hardware related but it won't RR in download mode and I think its too big of a coincidence that it happened after the Cyanogen update. Any ideas?
My first and always main advice is that if you are unsure about your hardware the first step is to Odin back to stock. The reason is because it is a bit for bit rewrite back to the way the phone was intended to be run as long as you do a factory reset from Stock Android Recovery before it boots. This is how your phone was when it came out of the box and it is a great way to check if it has a hardware issue by looking for bad behavior when using the original drivers.
If you flash back to stock completely clean and your phone is still acting crazy you might have bad blocks on your NAND, you might have issues with your RAM/CPU, or it might just be a loose hardware connection from heat or impact. But you can only truly diagnose those from Touchwiz because the drivers are first-party, not reverse engineered to be compatible. If you can reinstall all your apps and use it normally for a week then your hardware is good and CM was the problem and you should try another AOSP build.
I am on the 09/09 Nightly for CM and I can tell you that I have no lag or issues on my device at the moment for what that is worth. Good luck!
Thanks. I might just send it into samsung and see what happens.
Hey all,
Looking for some assistance here. I apologize in advance for not having specifics on everything, but it's been a couple years since I've needed to do anything with this phone (SM-G900A). I picked it up used a couple years ago and shortly after, I did a NOX unlock and rooted the phone for two reasons - using Titanium Backup and to unlock the WiFi hot spot. I recently noticed that something had happened and my root access wasn't working correctly- guessing from one of the OTA updates that was attempting to occur on my phone. I say attempt, because I don't believe they ever successfully installed since they always seemed to error out. I'm currently on StraightTalk, not an AT&T customer. Something weird was up with it though, because I could never uninstall the Xposed Framework or app, yet Pokémon Go was recognizing it was rooted and blocking my access. I should also mention that I had towelroot running on the phone and it's showing the custom unlocked padlock on startup.
Fast forward to last night- I wanted to return it back to the stock ROM so I did my research, found a couple different tutorials that included the correct ROMs and applied one - G900AUCU1ANCE_G900AATT1ANCE_ATT.zip. After flashing, the phone will not boot and freezes halfway through the swirls around the Samsung logo, then goes blank. The blue notification light also stays lit on the phone.
Thinking it was most likely bootloader related, I found another ROM that included separate AP, BL, CSC files. I attempted to flash the bootloader, which failed and I got the following error on the phone - SW REV CHECK FAIL : [aboot]Fused 2 > Binary 1
At any rate, it seems like my boot loader somehow got corrupted or isn't compatible with this ROM, but I was hoping some of you experts out there could provide some answers. At this point my phone is dead, so I'm hoping I can get it restored very soon.
Thanks in advance guys!
The issue identified in this thread (http://forum.xda-developers.com/galaxy-s5/help/g900a-stuck-samsung-logo-black-screen-d-t3050369) seems very similar to mine as well as what's described on this website- http://www.galaxys5update.com/fix-black-screen-with-pulsating-blue-led-on-galaxy-s5-g900a/
I'm seeing the pulsing blue light as well. How do I find the 4.4.4 OA1 Kernel identified in the first link?
