Hi,
I tried upgrading the camera firmware.
The upgrade worked, but after that I could not use the camera any more as it said "Camera Failed".
Here is the fix:
There are 3 steps for the camera to get onto the camera chip itself.
A: /system/firmware
B: Somewhere else on the phone
C: The camera chip.
Backup first:
Use the "CAM FW to Phone dump" to backup your current firmware.
I have not yet found out where on the phone this ends up, so I do not know how to copy it a PC for backup purposes.
FIX Proceedure:
Copy the new camera firmware to A.
Reboot the phone. After the reboot, the camera firmware will be copied from A to B.
Use the "Phone to CAM FW" option to flash the firmware from B to C.
Reboot the phone as requested, and you should then have a working camera again.
I used the camera-wave.7z to fix mine. (Found in another thread)
The "Show Camera FW version" gives totally bogus information. It shows only the FW version of the files at A, and not the contents of the camera chip itself.
Was this meant to be a useful post?
Yes. It has the FIX proceedure.
It contains an extra "reboot" step that if not followed, results in the same old firmware being flashed to the camera, and not the new firmware, thus failing to fix the problem.
after flashing wave fw no sgs fw worked for me so don't think it's really a fix - i could do that as much as i want - replacing fw and none would work then go back to waves. but the wave FW is pretty crapy against updated sgs fw in quality. in the end i went to service and they replaced my camera module.
are u sure it works?? my camera flash process arrives to 98% then it hold on for 5 seconds and then it tells flash success but nothing change!
I cant find any donwloadfile for the neuw firmeware...
can someone help me????
I made the mistake of using samsung aps to update the camera firmware when it prompted me to.
Unfortunately this was not successful and the update FC so no my camera does not work properly.
Auto flash does not work, and the video only works at night (low light conditions). There is just a white screen in the day (normal light conditions)
There is the service menu to manually flash the firmware, just 2 (*#34971539#) issues with this:
1) I no longer have a fw that works.
2) My camera thinks it has the latest firmware so will not allow a reflash.
So can someone upload the files they have in : /etc/firmware
there should be 3/4 files:
RS_M5LS_OB.bin
RS_M5LS_OC.bin
RS_M5LS_TB.bin
qt602240.fw
The M5LS files look to be the firmware files for the camera.
Also does anyone know how I can update the version in these bin files from oced11 to a higher version oced12 maybe. So the camera firmware flash will allow the update? Or is there anyway that I can force the flash?
========================================================================================
Ok fixed it, for anyone else that has the issue with the Samsung App updater failing on the camera update here is how to fix it:
Copy /etc/firmware/RS_M5LS_OC.bin to the pc
open RS_M5LS_OC.bin in notepad++ and search for the version number (in this case oced11)
change the 11 to 12 (WARNING: only change the number do not add other characters adding even a space may corrupt the bin).
save RS_M5LS_OC.bin and copy it back to the phone in /etc/firmware
enter *#34971539# in the stock dialer.
select "Phone/CAM FW Ver Check" if you have done the previous steps correctly the versions will be different (phone version will be +1 on the camera version)
select "Phone to CAM FW Write"
Once this completes (takes 3min ish) the camera is now working correctly.
The files I used can be found: http://www.mirrorcreator.com/files/0PEES0BI/CamFW.zip_links
Thank you for sharing, might be helpful if something fails while updating.
Hi!
The cam update corrupted my camera, too. I tried to follow your tutorial but there's a little problem: I can't find the "/etc..." folder on my phone. I do have root access and dumped the cam firmware to the phone via the service interface. But still I cannot find it when I connect my phone to the pc. Can someone pleas help me? Thanks in advance!

Don't look for it on PC , disconnect phone and download "Root explorer" from market ,then on phone itself with root explorer go to system/etc .
OK I found the folder with android mate. But there is no RS_M5LS_OC.bin only RS_M5LS_OB.bin, qt602240.fw and RS_M5LS_TB. I don't know what to do now.
edit: I'm not sure what happens if I took thelestat's file and put it on my phone. Maybe it's too risky...

Hi, looks like you are on the OB firmware, where I had an OC camera. you can check using the secret code in the OP.
Copy the RS_M5LS_OB.bin to your PC, Open itin notepad++ and search for the version the secret code shows you. Increment the number by 1, save it. Then replace it on the phone. Flash using the secret code.
If you want, post here the versions from the swcret code, and upload the file. I can do the editing for you.
Mine was dead too.I also can't find RS_M5LS_OC.bin,but i find RS_M5LS_OE.bin,OB,TB...but I open this 3 files,and I can't find the secret code(OCEE09).
Cam FW Ver: SCEF02
Phone FW Ver: TBEC28
Here are my files: w*w.mirrorcreator.com/files/1ONIHVSU/Camfirmware.rar_links
Hi,
It was in the RS_M5LS_TB.bin file. I updated the version to TBEC29.
The file is: http://www.mirrorcreator.com/files/QNQXTGZ8/RS_M5LS_TB.zip_links
Just replace the one on your phone and use the secret code to flash it.
I have OCEF02 as Cam fw and in firmware folder I have:
qt602240.fw
RS_M5LS_OB.bin
RS_M5LS_TB.bin
RS_M5LS_OE.bin
That's meaning I have installed RS_M5LS_OC.bin?
There is any chance to revert to TBEC28?
Thank you.
hi
i really can't believe it
i was flashing firmware update when THE ALARM RINGED!!!!!!!!
the flash app has crashed now i have a non working camera
do i need root to do this procedure?
I just updated my camera firmware through Samsung Apps. It all went fine, took a few minutes then I manually rebooted. Video, photos, flash all work fine.
Strange why it fails for some people. Maybe battery was too low ? Or different version of the camera hardware ?
btw now I have:
Cam FW Ver: SCEF02
Phone FW Ver: TBEC28
hi Thelestat
i rooted the phone now i'm stuck to the "version" part

Is it based in TBEC28?
Cheers.
i REALLY don't know what happened
i managed to find that the firmware on camera was SCEF02
so i managed to put SCEF03 on the file
i tried to flash it started but crashed after 3 seconds
the i gave a punch to the table (i think it helped )
then i go to samsung apps redownloaded camera flash firmware and it said it was the latest version
uninstalled it
gone into the secret menu, and it said camera version SCEF02 and PHONE VERSIOn SCEF02
i gave ok and it started flashing
that were the longest three minutes of my life :O
i rebooted the phone and :O it is working now
it seems to me that downloading the camera firmware update left in /etc/firmware the "right one".... and even if it was the SAME version of the actual camera firmware, it worked
i'm really happy i was worried to have to send the phone to samsung.....
thank you thelestat... really, thank you!

Hi everyone,
I recently bought a Galaxy S2 and I'm getting a "camera failed" error whenever I try to start the camera. I even tried to instal some other camera apps from the market but same error.
Can someone please guide me what is wrong with my phone?

I'm confused now, thelestat. This is the exact version of my cam firmware. Is the file you updated for me still the right one? Sorrry, but I'm a little bit frightened of flashing the file. Can this cause serious harm to my phone if something goes wrong? Thank you so much for your help.

Yeah it is still the right version. It's the file you uploaded with the version number changed.
It is the exact same firmware as the samsung application tried to update, the change I made, just allows for the secret code flash option to work. It checks for a newer version before it allows the update.
It is unlikely to effect the rest of the phone, as it is only writing the camera firmware. I have used the secret codes to read an write a number of times, and have never had an issue.
I am not able to flash it: Invalid version TBEC29
Phone/CAM FW Ver Check:
Cam FW: SCEF02
Phone FW: TBEC29
By the way is it possible that there is no firmware version called TBEC29 out there? This would explain why it doesn't work.
This sucks...
I am unrooted running a stock B180 right now on my PLK-L01 Honor 7 device. I have over the past few months waited for Marshmallow 6.0 Upgrade as it was promised that it would come over OTA the start of this year. Though it hasn't so I decided to manually upgrade the software so I downloaded the latest full version firmware of B320-330 from the hihonor UK website. The software installation goes fine up until 60% then suddenly I get an error message saying "software failed". Why am I getting this error message when the firmware is correct? I am located in Sweden and the closest region to mine is UK so therefore I got on their website and downloaded this firmware. There is only 1 firmware that applies to the Europe region because there is no firmware that's particularly for Sweden itself.
Funny thing is even though I get an error message "software failed" the device still reboots and the Android v.6 works perfectly. If it does not install properly, marshmallow shouldn't even be working! Guys what could be wrong please help! I want to do a clean installation without any error message.

this is normal!
Now you can redo the update process with pressing vol+ & vol- & power button for more than 3 sec.
After than the update process starts again! This time it should be finished with 100%.
Thanks for your reply,
Really? That's strange. This is the first time I am to believe that even after an error message something works just as good. So just after the error message shows up I need to press vol+,- and power button at the same time so it will resume. Didn't know that. Instead what I did was I did a rollback to B300 and then updated to B330 this way I didn't get any error message. Very cumbersome.
If you are on B330 now, you should know this code too: *#*#2846579#*#*
If you enter this code, you will see a new service menu! This you need to manual update in the next future!
To manual update, you have to copy the update.zip into folder "dload" at your ext.sd.
After than, you use menu point 4 to have the possibility to start the update process manuay.
So don't forget this code.
Yes I know that code but honestly it doesn't matter whether you use that code or do a forced upgrade it still results in error message. Yes I did exactly as you are saying even before your message that's how I did it.
A question I have to you. If sometime later I regret and wanna go back to b180 can I do so and still get the marshmallow update OTA? Like going back to the stock b180 software which I had earlier or before I did any manual upgrade at all.

this should be possible. -> Rollback B300 -> reboot -> now you are on B300! -> Update B180 Full rom from the Honor page -> reboot.
If all is going right, you are back on B180.
During the rollback, all datas will be erased! So make a backup at first!!!
See my signature point 1 & 2!!!
BTW: I think there is no difference between the manual or OTA update becaus e it is nearls the same procedure and it has the same file.
Maybe it is possible to extract the B330 update.app with honrorextractor. Than you have to flash most of the extracted files with fastboot.
(Boot; Recovery2; Recovery; System; Data; Modem; Cust; *.img files)
After the next reboot (fingers crossed!) the update procedure should finished without errors.
Yes that's the way I had imagined it to be, doing a rollback to B300 and then downgrade to B180 however will this be the official stock firmware? What is signature point 1 & 2, I don't understand?
Also, where can I get the honorextractor from? Never heard of it besides flashing and fastboot all refers to when the device is rooted and mine is not. I am familiar with these terms as my previous phone was rooted so. I don't understand this boot, recovery, data ,modem, cust part etc its very confusing

hi Harman, sent you a private message if you can reply please. thanks
Just got my Axon 7, shipped from DE to UK, thought I'd try manual software update.
Current version listed as ZTE A2017GV1.0.0B06
It times out with Network Unavailable despite the fact it is connected to WiFi and Chrome works fine as well as everything else needing internet connections.
I am on Three UK, haven't tried updating without a SIM ... is that worth trying? I did see at initial setup I was prompted to accept some sort of 3UK profile though I assumed this is just APN/MMS stuff.
Anyone else having similar problem trying to update?
I see talk of updating to B08 etc, from 2017G --- is 2017G same as 2017GV1... wouldn't want to assume anything this early on in my game
TIA for any tips/advice.
Am really liking this phone though, might be nice to get latest update for security mainly, not sure if many features are added?
Same issue here as it happens, though I'm currently trying to update WITHOUT a sim (didn't appreciate it was nano so new one on order!).
I was thinking it maybe needed one to be present to update, but clearly that's not the case.

Can't speak to the EU version, but I was surprised when my A2017U would not complete initial setup (& update) without the SIM, although wifi was strong. All completed quickly as soon as I popped in the SIM.
Hi,
I have the same issue here.
I've just bought A2017G from Italy (Amazon) and I live in France. Can't have the upade to B08. There is always this message "No network" after a minute of searching. I tried with 4G and Wifi and there is the same issue!
Also can't connect
Same issue here. I am already on B.08 and have wifi/Sim in place.
Mysterious problem
I have tried many solutions but I wasn't able to update :
- used three different sim cards from 3 operators
- removed sim card and worked only on wifi
- used VPN
- tried to update via SD card form the update page and from recovery
... Unsuccessful !
Anyone have idea?
I'm also having the same problem. I live in Sweden and I just got the phone today. Would be nice if I could update sometime soon.
A2017g b06
Greenland here, I also have problems with the connectivity
Maybe ZTE is updating its servers so that the updates can finally deploy at the same time, the same version, for everyone.
Or, maybe... they are silently getting rid of Adups and moving to another kind of upload process, before **** hits the proverbial fan.
Also, Global Axon 7 here, brought via Amazon.es, sent from Germany and now used across Portugal/Spain. Running 0B08.

I can understand that, but even if we put the B08 update file downloaded from ZTE support in SD card, the update can't be processed.
Hello, I had the same problem, I reinitialized the Axon 7, and I copied the file update.zip B09 on the phone, it recognized and installed the file (I was on the b08 before)
Hallo, i have the same problem with update, I have B06, somebody can give me a link to download the latest firmware and how to install it.

hmm I put a b09 in the sd card and it updated no problem
Solution found!
I’ve already found the solution for the manual upadate from SD card and it’s easy to do.
Theses instructions are not mine and I’m not responsible of what you do with your phone. I found them inside the update file that I Downloaded then I unzipped.
You will find a PDF document called “ZTE A2017G Upgrade Guide (through an SD Card).pdf”. You can use it to do the upgrade step by step.
Till now, all was OKEY: backup is very quickly with Zte app. The update take about 5 minutes, than the phone restarts automatically.
If you cannot find the B08 update file, try to download it from here: http://www.ztedevice.com/support/detail?id=98CEB24F9FFD433EA99EC424163149A6
Here are the steps (exactly as mentioned in ZTE Upgrade Guide)
ZTE V7 Upgrade Guide (Through an SD Card)
1. Backing Up the Data
1) Download the upgrade package.
Open http://www.ztedevice.com.cn/support and download the upgrade package (update.zip) that matches your phone model. If the downloaded package is not update.zip, unzip the package to obtain update.zip.
Ensure that your micro SD card is at least 3GB.
2) Remove the SIM card before the upgrade. Back up the data and APPs in your phone by using the built-in Backup function. To enable the built-in Backup function of your phone (an SD card must be inserted), select
Backup and Restore from the main menu。
3) Perform data backup.
Note:
You should not remove the SD card during the backup process. To avoid data lost, it is not recommended to cancel the backup process.
4) Verify that the update.zip file in the root directory of the SD card
matches the model of the phone. Do not modify the file name and extension name of the files in the upgrade package.
5) Verify that your phone has enough (at least 30%) power. Charge the phone if required. To avoid data lost or upgrade failure, it is not recommended to upgrade your phone through an SD card when the phone is being charged.
Note:
You should not perform any other operation on the phone during the upgrade process. To avoid upgrade failure, do not forcibly remove the battery.
A normal upgrade should be completed in 2-3 minutes. If the phone does not reboot or show any response in three minutes, you should perform the upgrade process again. If the phone cannot be started, perform a forced upgrade. If the forced upgrade does not work, you should contact an after-sale service agent for support.
2. Upgrade Description
There are two upgrade methods: normal upgrade and forced upgrade.
If the phone cannot be started properly, for example, the phone cannot be started, or the phone does not enter stand-by state, perform a forced upgrade. If the phone can be started properly and the Settings menu can be selected, perform a normal upgrade.
3. Upgrade Steps
A. Normal upgrade (the primary upgrade method)
1) Download the upgrade package that matches the phone model from ZTE official website (http://www.ztedevice.com.cn/support/), extract update.zip from the package, and copy update.zip to the root directory of the SD card (the file name must be update.zip
2) Select System Manager > File Manager> SD Card from the main menu, and verify that the update.zip file in the root directory of the SD card is proper.
3) Tap the main screen is displayed. Tap and select SETTINGS >All setting > Updates>,
4) Click INSTALL, The phone automatically powers off and reboots. the SD
card upgrade screen is displayed,
After the phone is upgraded, it is rebooted again. After the phone starts properly, it is recommended to manually restore the phone to its original factory default settings. The phone is upgraded properly and can be used.
B. Forced upgrade (for the phones that cannot be started or the phones that cannot enter standby state)
1) For a powered-off phone, press and hold both the volume key + and power
key to enter into Recovery mode.
2) Press the volume key - to select apply update from sdcard, and press the power key to confirm it.
3) Press the volume key - to select the update.zip file, and press the power key to confirm it. The phone completes the upgrade process in about three minutes.
4) On the Upgrade Complete screen, select reboot system now and press the power key to confirm it.
4. (Optional) Restoring the Data
If you have backed up data before upgrading your phone, restore the data.
1) Backup and Restore important user information.
2) Perform data restoration.
Note:
Do not remove the SD card during the restoration process. To avoid data lost, it is not recommended to cancel the restoration process.

The file is on ztedevice (link in thread) but i think (as some of other users) that this patch is only for Spain - don't know that for 100% but most ppl that can upadate it with OTA are located in Spain. Also I still get "network unavailable" when I trying to check update (location Poland, phone from UK). But you should can update from B06 to B08 as I can without any doubts via OTA.

Here the problem is solved, this morning the ota update worked en now he is installing B08.
I downloaded B09 en wanted to go install it and than the give me the original B08 update in the screen, let see how it works.
As for 1.01.2017 update check start working for me - no more "network unavailable" just "up to date" at B08 a2017g.
I have an A2017U but since changing from stock rom B35 to B01, I have lost all sim card and phone functions. I've tried all these - B05, B15, B10, B35, B20,, B19, but all firmwares are identified as "not for this machine" error, and all relevant apps and "About Phone" information now indentifies the model as A2017G, which it certainly isn't. Is there a rollback set of firmwares I could use to regain mobile network functions back to this phone. Firmware installed is B01, and when I bought the phone it had B35 installed. I don't have a PC just mac, so all those nifty workarounds, I can't do.
Please Help

Hello,
Assuming you have stock recovery, you can get ZTE_A2017UV1.1.0B35 firmware here:
https://www.getdroidtips.com/zte-axon-7-stock-firmware-collections/
Normally the download file should be a zip, unzip it, you will find update.zip file. Put update.zip on the root
of your SD card. Then go to Phone Settings, search for update, it should tell you your current phone version
and the update it finds and suggests. Then tap on update : it will update for you then reboot automatically. First reboot
should be a little long (< 5 min). Then you should be back all right to B35 and phone OK since the right modem for A2017U is included
in the ZTE_A2017UV1.1.0B35 firmware.
Note : I guess you have applied incorrect A2017G firmware to your A2017U, this would explain the phone problem (incorrect modem).
Fixed!

I used B03 stock room and still had no phone functions, then I did another SD Card update with the B20 and it worked, I have all the phone functions back and am on the latest stock Oreo build too, I'm so glad to get it back, as I was using a spare Android phone on version 5, it was so slow, but it's fixed now.

The key part of the method was to remove the Google account before updating in recovery mode
