Today I made a first step towards custom ROM by installing the latest TWRP with Odin and taking a backup of all partitions. Rebooted and unfortunately now I have IMEI null and baseband null (it was originally I9305XXUFOA1 I believe)
Nothing else has been touched, I am still using stock ROM, and reset to factory default did not solve it...
I still have the IMEI number and a backup of the EFS partition. But when I restored this partition with TWRP, I still have No Signal.
I searched the forums and only thing closest is a post about the S4: http://forum.xda-developers.com/showthread.php?t=2370699
Is there any suggestion on what I can try to recover this problem?
If I type *#1234#, I get
AP I9305XXUFOB2
CSC I9305PHNFOB2
But no CP?
Now I did a total restore of the backup made with TWRP, but still "unknown baseband"
In case it helps others, here is what I learned
When flashing TWRP 2.8.7.0 on my 9305 with Odin, my modem becomes unusable every time.
It can be easily restored if you have the modem firmware, so that solved it. But it seems TWRP is very unreliable until I downgraded to an older version of it, 2.7.0.0. Now everything is working, although it can be tricky to get into the recovery mode (holding buttons for up to 30 seconds). I suppose this is normal behaviour...
Help please

Hi, I'm going nuts reading for the past 5 hours all the info about this issue and the multiple solutions i have tried with no success, i just stumbled in your post which describes exactly my problem, after flashing twrp bam!!
I have no backups, i bought this phone yesterday, unrooted this morning , spent some hours customizing stuff, got to the point to install a recovery to do a nand backup as the phone had all the apps and settings i wanted and this just happened, i am now going to do a complete stock flash, will it repair my modem? If not can you please provide me with a link to the modem firmware? Is it country associated, will i need a specific for my country/operator?
Thanks,
Bruno

Hi Bruno,
You should try to (re)flash only the modem with Odin. It's not so difficult, just take your time to familiarize with the steps.
To get a modem.bin, either you extract it yourself from a stock rom zip (see http://www.sammobile.com/firmwares/) or get one from the topics at xda (for the 9305 I got XXALK2 from http://forum.xda-developers.com/gal...05/modems-i9305-cwm-flashable-modems-t2010116).
I suppose you have no access to TWRP right now? If so, reflash it with Odin too. I recommend version 2.7.0; it works for me very well. Then immediately take backup of everything (EFS etc) and transfer it to your PC
Let us know how it goes,
SOLVED: Null IMEI and baseband
Hi all,
My problem is solved, after flashing the latest stock ROM for my model (I9300) I got my IMEI back and everything back to normal, as told I could have just the modem.bin flashed but I went for the full re-image.
Then i unrooted using cf-autoroot and flashed twrp version 2.8.6.0 instead of 2.8.7.0, rebooted and everything ok. I already performed a full nand backup and learned various lessons from this. I think guys at TWRP should know that their latest version for the galaxy s3 is causing this problem, i believe most people will send their phones for repair because there are so many possible causes for this problem and so many xdifferent possible solutions that most people will quit solving the problem and will try to return the phone for repair.
Thanks for your reply and for the help. I will send an email to twrp linking to this thread.

Search on P9 ROMs section for HWOTA7
Or older/simpler HWOTA - you will find instructions in Magic Rainbow v4 (also P9 ROMs section) - MR v3/v4 had clear instructuns how to go back to stock, applicable also to other P9 Nougat custom ROMs
Of course assuming that you don't want to go from Chinese Oreo back to Nougat - then the procedure is different but it is also clearly described in the corresponding HWOTA7 thread OP instructuns
Hey,
I need your help with going back from RROS to stock EMUI.
Im trying this since a couple of hours now but I dont get it.
So I started flashing RROS with the new TRWP everything worked fine but the battery drain was to big so I decided to restore to the nandroid backup I did before flashing the custom rom.
But there was the point I did anything wrong so... My device just bootloop now and I dont know what to do.
I tried the dload option to rollback to stock for so many times and in the end I got a bootloop again so can anybody help me with this sh*ty smartphone?
Id be so glad if anyone could please help me, Im so desperate :/
Why you didn't ask first for instructions in the RROS thread - supposidely the RROS authors and users should know how to go back (they are subscribed to and they read their thread)
I'm not sure if DLOAD method works from RROS.
If you still have TWRP, you can try

Thanks a lot Im goona try the first one but Im not sure its really working because I used a nandroid backup of another user from version B384 and flashed OEM info packages.
I dont rollback from full RROS so I dont really know in wich thread I should write.

First method, HWOTA, does not recover OEM Info - you should have never flashed Nandroid backups from another users.
I would suggest to go anyhow back to stock Android N, then to do rollback to MM and back, by OTAs to Android N (stock ROMs)
Btw, what was your orginal stock ROM, EVA-L09 c432 b384 or what (L19, etc)?

I got a L09, I dont know my stock and the ROM I moved over to RROS too.
However, Im going back to RROS with the nandroid backup I did before all this **** and then Im trying HWOTA.
Rollback doesnt work, I tried it with the stock and nocheck recovery, two times package errors.
Edit: restoring nandroid backup of RROS failed, with extractTarFork() error 255.
Im starting now with the HWOTA method after flashing the rom again without backup.

HWOTA method requires that you use ZIP corresponding to your original stock ROM you had.
This is because HWOTA actually uses no-check Recovery to force DLOAD to the chosen stock ROM, but DLOAD does not recover/reflash all partititions, they must be original/in sync. If not, DLOAD (as part of HWOTA) will probably fail.
You should at least know what was your original cust for L09, was it c432, c185 or c636 - to choose the corresponding HWOTA ZIP.

First of all thank you!
So... like I understood your post there ist no way for me any more to use DLOAD or HWOTA because I dont have any part of my stock ROM on my phone. Well, that doesnt sounds so good.
But what can I do then? How can I go to stock when I dont can use DLOAD or stuff like this??
Try with HWOTA and then try with rollback, maybe it will work
And/or try the second method from above (that one I never used).
Actually, that second method also utilzes rollback, to clean/restore all partitions.
Hence, it is important that you reach a point (having, even not fully functional, stock Android N) to execute rollback

I use the P9 L09 hardware version in Japan. I just installed rr 6.0 onto my P9 and now i want to go back to stock ROM. I had backup my stock rom with twrp (boot, data, system, vendor). But after I restore, my P9 hangs the logo. I waited 30 minutes. I just remembered updating the OTA to L09C635Bxxx NRD90M_test-keys but could not remember the number after B. tried L09V635B397 dload and fail. tried flash via fastboot boot, recovey, system extract from update.app but still stop at boot logo after I reboot to system. So what do I need to do to get back to the default software version? someone please help me. thanks so much. sorry for my bad English.

Every week or so a new user opens a new (but old) topic here, how he/she bricked the phone by trying to roll back fron RR to stock.
It's really boring to repeat the same each time again
I'm really puzzled with couple of questions
1. Why RR users don't post/ask in the RR thread
2. Why nobody searches on XDA (particularly in in this QA section) to learn how to do it properly, before bricking his phone
3. Why developer(s) of RR did not bother to advice users how to go back to stock. If he didn't bother to do it, why nobody else fron the P9 RR comunity did not bother either. After all, it looks like an intentional trap, how to screw up as many users and phones
This is the method to reinstall stock from custom ROMs like RR

You should have applied it while you were on RR, but maybe it can still help you

Really sorry if that made you feel so upset. I tried everything including HWOTA and not all. I am really impatient to set up this topic. After waiting for someone to respond to this topic, I went back to success by rolling back to android 6 and getting OTA back to 7.0. Anyway thank you for the answer.
closed topic. Admin please help me delete this thread. thanks again.
I know there are other threads like this but please read on.
I've installed the havoc os for the phone but I really wanna revert to stock with everything back to factory state including locked bootloader.
I have a LLD AL-10
I'm getting lots of annoying bugs now.
I did take a backup before flashing but it got corrupted because of twrp and upon restoring won't work.
I've seen lots of threads telling how to revert but none makes sense to me ?.
There was also a thread in the guides section on how to recover from bootloops to stock but when I use the second option it gets to 5 percent and shows an error.
I tried extracting the Img files from the update.app.
But while flashing it it gives some wierd errors.
When flashing the system.img it keeps on flashing again and again and dosent end , had to pull the cable and flash havoc os again.
I'm having an LLD AL-10.
I want to revert to factory condition.
Please someone provide detailed steps.
I'm all good and running now thanks to you guys.
Moderators kindly close the thread.
