Hey xda-forums,
after rooting my Samsung Galaxy S5 (Vodafone Germany) I did a backup of my data and copied it to my PC (It were 7GB).
Now I wanted to restore the backup, so I copied the Backup files back on my SD-Card. As soon as I start the restoring, TWRP says "Cannot restore Modem -- mounted read only" .
Is anyone able to help me?
-Issei
I get this all the time. I usually unchecked modem and restore everything else. I'd like to know why this happens, too, so I can fix it. In the meantime, just uncheck modem before restoring your backup. Someone will see this and know how to fix.
You can mount RW in mount section. Check modem partition
Did you manage to solve this? I check modem in the mount menu but it keeps giving me the same error.
Not solved. Any help?
Workaround
I have S5 Verizon (USA). Have the same issue. Member mjw1 found workaround:
"I realized that I am also facing this issue on my G900T. So at the moment, I'm using 3.0.2-3-M for nandroid backups, then dropping back to 3.0.2-1 to restore the modem. I know it's a hassle, but at least I'm still able to restore 100% from my backups with this workaround."

This worked for me.
why would you want to restore modem/bootloader? always get the latest version with stock ROM, install recovery, then restore everything back except modem, bootloader & recovery. you don't even need to boot to android to do all these.

It depends. For example if I need to add additional LTE bands (in my case 3 & 20) to Verizon phone, I definitely need the possibility to backup – restore modem if something goes wrong.
Still not solved- anyone have another suggestion?
I found a solution.
I was not able to upgrade my modem with odin after knox became 1.
By using an usb JIG and going in "advanced downloadmode" I was able to update my modem.
I got the same error
And not only on the "Modem", but also on the "System" part. Except these 2 partitions, all other partitions could be recover. Anyone know why? and how to fix this problem? Thanks!

What's your phone version?
It looks like you have locked bootloader
SOLVED- it is a twrp problem. You're using 3.0.2.2, right? Go back to 3.0.2.1 and all will be fine again. I flashed 3.0.2.1 and modem restores without a hitch
Hi guys
Does anyone have a TWRP A2017G backup their willing to share?
I've lost IMEI and MEID and am trying to recover
Seconded. I seem to be in the same situation. Don't know if a TWRP backup will help, but I've been unable to connect to the cellular network after restoring a full TWRP backup which I suppose I shouldnt've restored. Re-entering my IMEI via a TWRP module didn't help as well. Neither does the adb shell dd command that formats the EFS partition found in another thread... Restoring EFS I backed up a while ago didn't help me as well.
Thanks in advance.
I have tried going back to stock boot/recovery backups, flashing every single A2017G update and even tried Tenfar's tool to restore the removed backups in his thread. Cannot seem to fix
Only had this phone for 3 days and it's now useless.

Do you have a backup you could share?
As far as I know, the EFS bit is unique to each device. It contains your IMEI code, for example, which is unique for each device.... I can give you mine, but I'm not sure if that will help you.
I'll probably make a new thread asking for some help because I've tried about everything and I can't fix this mess on my own... I hope I won't have to send it back, no way of knowing they'll believe me
I've been doing some googling and perhaps we need a modem.bin file from a A2017G?
this is really not looking good
Hello,
i need help. I messed up my phone while trying to repair my only read mode system partition after boot.
Current state:
Phone CAN-L11 with EU Firmeware and working TWRP Recovery.
I did a full wipe, but have no data partition to restore, because this couldn´t be saved with twrp while i made my first nand backups during no read access to data partition.
My phone always shows 2 times the huawei logo and then boot in erecovery from huawei where i tried to restore, but it shows always "fail to get data" (wifi works).
When i restore all partitions backups that i own via twrp i miss the data partition (is the cause why it wont boot - isn´t it?)
Now i searched for any img that i can use to get my phone working again - anyone has a tip what img i could use (i have a huawei update extractor) - through twrp or fastboot.
Could anyone help me with a twrp backup or a img file of data partition - or has another tip how to get my phone working again?
Thanks for tips!

I think that you need a system.img, so you can flash. This system imagem would write everything you need, so you can boot normally.
Have you tried to dowload @bluesmoothie backup from dropbox from the Root and Recovery post?
Here is the link, in case you don't find it https://www.dropbox.com/sh/qrk0fbpn5rnukxn/AAAmhFwBTNoqq0sWfCH-VMHLa?dl=0

Here the full Backup for the CAN-L11:
https://drive.google.com/open?id=0B134drJ4-Ed0R3VSY3A5NGpjVWc
Format /data, reboot recovery and than restore from backup. After the restore is complete make a wipe.
I restored my system from twrp (original first save). But that did not help.
After that i loaded the can-L11c432 update.zip from huawei and extracted with others the system.img - that also did not help to boot.
Tomorrow i flashed the orignal recovery.img from c432 but i did not find an update.zip wich works to manually flash in stock recovery.
@Vinnom the link you shared leads to twrp.img (no system.img).
@-=MoRpH=- thanks, i will try and report back. Is this anyway a chinese version in there? I think i have the same struggle you had days back. Is your phone completely working again?
So sick that my phone did not work. Now working with my "old" LG G2...
I report back later - first family dinner

Inside the folder twrp and its subfolders there it is system.img. I'm downloading it myself.

@merlin21 yes it sounds like my problem after I tried to flash the emui5 beta.
My phone is fully working again with the backup I posted.
This is not the Chinese version, if nothing works, you can try the caz ROM. But there are massive problems with the gapps, they are not included in the rom.

i just flashed the twrp.img with fastboot from xelfmade v22.12. and then rebooted twrp.
Then formated data and confirmed with yes - rebooted recovery and tried to restore your twrp. It did not restore and aborted instantly with the error message
during restoreing cust...
extractTarFork() proecess ended with ERROR: 255
what could that be?
IT WORKS! Thanks @murph... I had to use the cust from my backup, but with your data partition it successfully booted again. Locking forward if i now have still the problem with read only system partition. I am away setting up phone again (and of course rooting, modifying etc.. but FIRST do a full backup after basic setup and safe in PC !!!)
Thanks!
P.S. how did you manage to back up data partition in recovery? I thought this wouldn't be possible?! What is the cost for having this full working twrp?
PPS. Somehow knock on screen for screenshot does not work - could be, that i have to log in with huawei id... does it work for you morp?

That only work if the is not rooted... Idk whats up with that, but for now i use the quicksetting screenshot function.
Somehow it worked with my rooted device before. Must be the decrypted data partition?
With the recovery of your backup I could not access data or change memory from data to sd. What version do you use?
I flashed xelfmades v22 and now have rw access and could backup all partitions and restore. Root and xposed modules everything works, just the knock on screen to capture don't...

May I ask how?
I'm kinda stuck personnaly. I have tried both Nand backups but no cigar. Still can't boot. I had the Data issue which I managed to get rid of.
I still end up with a ExtTarFork 255 kind of error. I tried to change the files attributes via adb shell, but it failed so I've got an OS-Less phone...
Any help would be greatly appreciated.

I copied the backup, which is linked somewhere in this thread, to my sdcard and restored it on my Nova using twrp. The extractfork issue showed up while restoring '/cust' so i disselected cust in the restoring menu. After that the restoring worked and my nova was able to boot.
Hope this is any help to you.

That didn't do the trick for a while, or I might have forgotten a step, but deselecting CUST did the trick.
Thanks for the tip!
Although, maybe flashing the Cust partition I found in one of the two upgrade zips via fastboot might have helped? I dunno...
But in short, for those who haven't followed through, here's what I did, but I'm not sure this is why it worked:
1. Bricked my device : be sad;
2. DLed all the posted Nandroid backup on this thread and others;
3. With fastboot, reflashed TWRP from Xelfmade using "fastboot flash recovery twrp.img";
4. Flashed the CUST.img I found in the UPDATE.APP of the update_data_full_CAN-L11_hw_eu.zip; or maybe the other, only one of the two seem to have it; I extracted it using Huawei Firmware Extractor; using "fastboot flash cust cust.img";
5. Created a "fake" backup to create the right folder structure on my SD (TWRP Couldn't see the backups) and put the Nandroid Backups I DLed earlier in it;
6. Reboot in TWRP and Restore all partitions except CUST;
7. Reboot, sweat, wait, cry, roll on the floor in fear, heard the huawei startup sound, cried as if it was my first born child;
8. Setup the fone and profit; then enjoy Nova goodness;
92.324. and probably most important, TWRP BAAAACKUUUUP!!!!!
All done!
Thanks for your help my phone is saved with your method!!!
i downgraded my MLA-L03 variant with this, but now im stuck in french language with no other languages to choose from

Frankly, I don't know. I had not modified the partitions prior to bricking my phone, so I think the partitioning was OK. However, I think one of the TWRP availble in this forum can format Data partition properly, which would utlimately allow you to select which File Format you want. I haven't tried it myself, and I haven't been able to do much with TWRP since I flashed Lineage unfortunately. Most of my Mods were just upgrading and I had to ADB Sideload pretty much everything since I flashed Lineage...
Sorry I couldn't be more helpful than that!
Hi! I have a hlte/SM-N9005 with LineageOS.
Today I tried to turn on encryption, but then I was stuck in a boot loop. I did a full wipe in TWRP and restored everything from the backup I made before (including the modem partition).
My phone boots again (without encryption), but isn't able to detect any SIM card suddenly. Not sure if something went wrong with the restored modem backup?
I tried downloading a Swiss firmware from this link, extracted it, and flashed modem.bin and NON-HLOS.bin via Heimdall - this didn't help either, though. I'm kind of out of ideas now... Any idea what's going wrong?
IMEI correct ??
Phone Status > Status > IMEI information says "IMEI: unknown" :-/ I'm guessing this is supposed to be there, even without a SIM?
Restore your backed up EFS folder .
Restoring the EFS folder from the TWRP backup is what got me into this mess in the first place. There's probably supposed to be a /efs/.nv_data.bin in the backup, but there isn't for whatever reason. I don't have older backups anymore either.
Hello guys. If you ever lost any of your wireless connectivity and sensors for flashing any other rom then I have a backup files here via twrp. I just don't know how to make them into flashable so I just compressed it in case you need it.
I've lost my sensors and wireless networks such as fingerprint, signal, Bluetooth and wifi when I restored a backuped system in twrp. I did so many things like restoring its efs, flashing its NON-HLOS.bin file, reverting back to stock to no avail. It just gave me a headache because my bootloader got unlocked again so I unlock it for the 2nd time and it succeeded.
What I did was:
Flash back twrp(persist error occured, then I cannot flash any rom)
Restored efs, and persist on my backuped ( I just remembered that I have backuped the persist)
Reboot to recovery
Flashed RR rom (as usual along with Gapps and SU)
And it succeeded
Waited to boot and I got shocked when everything on my phone was back to normal.
So I am sharing this twrp backup file for you in case you guys need it.
you are sharing your IMEI and other important things remove it or anyone can misuse it
I want to know which file is to be restored to get modem back from twrp backup folder ?
