Differences between firmwares? - ZTE Axon 7 Questions & Answers

Hi all,
I just ordered the A2017 from aliexpress.
I have a question : once it arrives, are there any advantages of flashing the US or EU firmware as opposed to staying with Chinese firmware?
Also, I searched and found many threads that say the Chinese version doesn't have capacitive buttons, but the seller claims the phone does have them (it's the 128GB 4GB RAM version) so which one is the right answer?
Thanks a lot.

The 4gb ram 128gb rom has the buttons like the 64gb model. They don't light up.

Also, before flashing any other version of firmware, you MUST unlock your bootloader...

Thanks for letting me know

Yeah thanks, but what are the advantages of flashing another firmware?

None as far as I know, the Chinese version, aside from having Chinese apps included and no google looks to be fairly stable.
The European verion seems to have a few limitations due toregulations there - the most annoying I've seen is the earphone volume limit - and the US seems to have some translation errors (odd they aren't in the Chinese rom) but is the easiest to unlock bootloader and has some developement for.
Ultimately, if you cn unlock your bootloader, make sure you keep a copy of your boot image and recovery in case of problems, you can go to what you want.
Mixing boot images and recovery images is a bad idea however as it seems to cause issues with WIFI and could cause other problems too...

Chinese update
Excuse if I bump this. Bought a mobile in China with data below. Works like a charm, WiFi and GSM is as Galaxy 6. Sound is very good. Camera could be better, especially in dark environment. When I try to update, I get the message that it is already up to date. Are there no more updates for the Chinese version?
Version is zte A2017CTJMV1.0.0BM1

Yes, I have B13...
Go to this thread - http://forum.xda-developers.com/axon-7/development/axon-7-chinese-stock-roms-t3436817
Update to B11 by putting update.zip on sd card. You will probably loose the ability to boot after this so BACKUP everything you want to keep onto an sd card from internal memory.
Update, if you get a message after it restarts asking for a password you'll need to format data (Again, BACKUP 1ST) . Do this in recovery.
You should then be able to update to B13 through update in settings.
Now, you will need to, after 1st reboot, go to ZTE marke and enter "Google Installer". Install gmail, play store and Google Play services.
After installing all these items, find Mi-Assisstant in your apps. Select Auto-run. Tick the above installed google apps . Log into Gmail, it will say you need to update play services. It won't be able to do it for about an hour. Keep trying then you're back to the latest stock rom...
I believe the rom has been altered if it came with Play store and google installed, thats why you can't update...

How to fix your Chinese Samsung Galaxy I9220, (add google market and stuff)

Hi,
I live in Shanghai, China. Everyone who lives here knows that any phone you purchase here , even good brands (such as Samsung etc..) will not any have google applications installed. It's almost impossible to get these phones fixed without changing their roms, which is inconveneint and dangerous. From my personal experience once you change the rom of your chinese phone to a foreign one, you will never get the optimum performance. I first purchased a Samsung Galaxy S5660 in China. It worked perfectly expect for the fact that I couldn't use any google app. After being unable to add these applications, I finally flashed some rom from Europe. Then the market etc , all google apps worked fine but the performance was bad. Battery life was really poor. Also I changed several roms after that , none of which gave me the same performance which I had with the original chinese rom.
Now I have got a new Galaxy Note (not N7000), in China it's called I9220. I ran in to the exact same problem. No market, no google , absolutely nothing!! After a lot of research I was able to fix it this morning. If you have got the same problem then follow the steps. Here is how you do it!..
(But I must warn you that I am not responsible for any damage to your phone. Please do it at your own risk).
First use this video guide below :

In the above guide follow both recommendations. I mean root your device and then also change your kernel to FrancoICS. Both worked on my I9220 without any problems. My phone started and it was already rooted. Also I got the Clockworkrecovery as the default recovery.
Once you have finished this task, the final task is adding all the google applications. This is quite easy and I did it myself.
1. Go to the website goo.im/gapps and download the latest ICS gapps zip file, currently it is gapps-ics-20120429-signed.zip.
2. Save it to your external SD card.
3. Reboot into Clockwork recovery mode (you should know how to do this if you have already succesfully rooted your device using the above method)
4. Choose "install zip file from external sd"
5. Find the Gapps file and install it.
6. Done, and restart your phone.
You now have your Original Stock Chinese rom, but it's rooted and you have installed all google applications. Just make a google account and you can use the android market.
Even with the google market working , you cannot access many application since you are in China. If you want to be able to download all applications available in the USA for example, then you must also install marketEnabler.
Here's the link :

//Just google search market enabler, you will find it very easily.
1. After you install it, run it and choose T-Mobile (USA) and then click Fake this provider now.
Now if you use Google Market, you should be able to install or download almost any app (such as youtube, facebook, skype etc...)
I hope this is helpful to all the foreigners in China who are tortured by Chinese android phones that only come with Chinese bloatware and doesn't allow you to install any English app or access google stuff..
Good Luck!
Note : When I got my new phone today, it already had ICS so this whoe process worked for me. If your chinese I9220 isn't ICS, it's gingerbread, then don't attempt it, because it might not work.
Thanks a lot. It works on my Samsung S7562 which bought from China.

first switch off your phone then press the three button combination i.e. power +home +volume up and then when you see it getting started(when your phone model no. is shown up) then release the power button and continue pressing the other two buttons i.e. home +volume up

lol you are funny, Franko kernel was developed at xda, he quit developing, not sure why could have been ungrateful community, Its always had lots of bugs, but if it works for you it works. I wouldnt be surprised the rest originated from xda as well.
You better be careful with cwm. zip its been known to superbrick devices. Safest way to root would be the drPhills superuser and busybox zip, flashable as a upgrade zipbfrom stock recovery.

Samsung GT-S7568 China Model
Hi There.
I am new to this site but feel the solution posted would have fixed my problem had I found it before I tried messing around with ROM’s.
I have just returned from Shanghai where I purchased a Samsung Galaxy Trend GT-S7568. This model appears to only be available in china from my research. It is an original Samsung product not one of the many fakes out there.
In my attempts to get it to work with an English ROM, being the idiot that I am. I never created a backup of the system. I appear to have soft bricked the phone and I am unable to find a tool that can fix it. I am also unable to find an original stock ROM to attempt to get it back to the original Chinese firmware.
I have tried OneClick and I have also tried a firmware for the GT-S7562 (possibly what caused my current issue). I have found the Samsung official open source download page and have downloaded the correct files from there but have no idea how to prepare them to be transferred to the device as the “read me” file is not much help that came with the download.
Currently the Phone will boot into Download Mode but no matter what ROM I try The Oden Tool keeps failing at the complete Write operation.
I am hoping that I have posted this in the correct forum. If I not I am sorry but it is the closest I could find to my situation.
Any help or direction anyone may have would be greatly appreciated.
Thank You!

Thanks,my phone is GT-I9220, And this thread truly helps in rooting installing google apps.
What I want to add is to prepare an external sdcard before watching the video,
ar....
i have the i9220.
All i have to do is odin the stock rom from Hong Kong. (available @ SamMobile)
It is fast and stable, no problem whatsoever, and it has good battery life too. (that is only if you do not activate everything and keep you account in sync as little as possible, i only have google and facebook under sync.)

Hy, i'd like to root my S7568 as you did. Did you use the same files for Galaxy note as it is showed in the video?
Thanks!
Can't root my chinese mobile! Please give me some hope!
Hy everybody!
As I have bought a chinese samsung mobile, I can't use google play. So I'm trying to root it. I went through many software as Root_with_Restore_by_Bin4ry_v30 , SRSRoot for Android , SuperOneClickv2.3.3-ShortFuse and more. I also tried to do it as it is said in thoses previous post but there is nothing to do...
I think it's because my mobile:
Samsung GT-S7568
Ice cream sandwich 4.0.4
Is only available in China and all thoses software may not support my device.
So here comes my question. Do I have still any chance to take?
Thanks a lot!

PS: the mobile is not a fake!

Need Instructions to avoid almost bricking again

Hi guys. I very narrowly (somehow) managed to recover from almost bricking my phone.
I successfully S-Off'd my phone, and previously successfully installed TWRP. I tried to install this ROM:
https://forum.xda-developers.com/ve...m-perfumewl-m60-dev-edition-unlocked-t3442969
When I tried the to flash the ZIP for firmware and for the ROM, the firmware wouldn't install. I tried some other stuff and basically almost bricked my phone. Some how got it to suddenly start being able to use the htc_fastboot commands (????????) and was able to start installing the zip for stock... but it ran an error, I ran it again and it froze... then I forced my phone to reboot and somehow I'm back to having a stock system. No clue what I did.
My question is, can I take a software update on my phone normally (to 7.0) , and then install just that ROM? Or so I need to flash the firmware separately with a command line command? I just don't want to give myself another heart attack tonight. Current firmware version is 1.82.605.6, not rooted, don't believe my recovery is TWRP right now (but I know how to install that one).
I'm just looking for root access and the ability to remove pre-installed Verizon crap (VZW Messager, My Verizon, etc). Thanks guys.

I recommend you install this one instead:
https://forum.xda-developers.com/ve...m-1-85-605-9-aroma-root-root-debloat-t3529732
Follow instructions in OP...or:
1)fastboot flash FW w/o Boot w/ TWRP (htc_fastboot oem rebootRUU, fastboot flash zip...)
2)htc_fastboot reboot-bootloader
3) Finally, go into recovery-- backup and flash ROM (choose root w/ Magisk and debloat)
Thanks, I figured out why it wasn't working before. Used official TWRP, thats why it wasn't working. Wouldn't have thought that'd made that much of a difference.
New problem though; something I really would like to use the Google versions of contacts and dialers. Trying to flash those just made my phone app unusable. So I turned to LineageOS but it REFUSES to boot. Hangs on their little vertical line with a moving circle. Found out AOSP roms don't like VZW firmware? Flashed global firmware, updated through WiFi as much as possible, and then ran into issues with radio, even though I flashed the VZW one. So I reverted those changes, am going through with what you said above to have a working phone (after not having one all day), but any advice on getting Google dialer and contacts? I'd like to use LineageOS but I couldn't get it work at all.

You've got to read OPs, search threads, etc. Some ROMs work w/ our phone, and some do not. Check out the latest versions of ice and leedroid. Your most likely want to grab the SVN versions is the official versions may not yet support Verizon N firmware

I have been doing a lot of searching, but I've found so many different, conflicting sources of information. For example, one website told me to install LineageOS, was to be on latest Verizon OTA and just normally flash it; that obviously didn't work.
So from what I can see, our choices are Viper, Ice, LeeDroid, NuSense and the one you linked. I'm going to try out LeeDroid... out of curiousity, is there any reason, for example, LeeDroid or Ice haven't posted in this Verizon section with links to their ROMs?
*Edit Two* Dialer wouldn't work out of the "box" so to speak, so I had to go to Phone settings at the bottom, there is a menu called Calling Accounts. Had to go there and tap Receive Incoming Calls... why is that disabled in the first place..? But that seems to be an issue going even as far back as the Nexus 5. But that's how you find the option in the HTC 10 for anyone who comes across this issue too...
Not sure why your having issues with the flashing. Are you doing a full wipe? Not just factory reset. Going from stock to lineage requires a complete format of internal SD card. On the stock roms, most will ask if you are still on marshmallow firmware & are working fine. Again, we need more info on what firmware version your on, version of twrp& how your wiping your device. Most AOSP roms work, but no advanced calling
LOS ROMs will work without issue IF you have flashed the US unlocked firmware at some point in time. This is the only information that we have found from a VzW device with LOS booting and VzW device without. We started a thread awhile ago and is the only known method we currently know of to get LOS booting. Also works for Sprint users.

Axon 7: No connectivity after upgrade to 7.1.1

Hi
I have Axon 7 A2017G. Bought from AliExpess in Feb of this year. It has been a very good phone so far with no issues. Well, at least until yesterday.
I was on Android 6 until yesterday when I found out that I can upgrade to Android 7.1.1. So, I stupidly upgraded to 7.1.1 (getting the upgrade from from ZTE) and now I have *lost my connectivity* (I am using three.co.uk sim). It doesn't recognise my sim card at all.
I have tried deleting and wiping the cache - no joy. Not sure what else to do.
I tried to use other upgrade from ZTE (Nougat to Marshmallow) and Marshmallow. Both fail with 'e footer is wrong e signature verification failed installation aborted'.
Everything else seems to be fine and I have had no issues with Axon 7 (had it since Feb) before the upgrade.
Hope someone can either help to get the connectivity back or somehow degrade my Android back to 6 (when it was all working fine).
Thanks Robie

The problem is probably that you do not have an A2017G. Turn your phone around and tell me what the model erched into the back of the phone is. I suspect that you have an A2017, you didn't read the little paper that came with the phone that explained what they (the aliexpress seller) did with it, and you flashed an A2017G ROM on your A2017, effectively messing up the modem file.
I don't know if flashing through EDL fixes the issue, but it might be worth trying. It involves downloading a FULL_EDL package (the full system for your device model), then flashing it entirely through EDL.
The failproof method is to unlock the bootloader, flash TWRP, then flash the modem file corresponding to your device.

Doh! Doh! Doh! :crying:
You are ABSOLUTELY correct. I didn't read that little paper that came with it because it was all Chinese - not English. Damn - why didn't I check. :crying:
When I bought it, the website said it was a 2017G model and therefore I assumed it was 2017G model.
Anyway, I don't understand some of the things you wrote (I am okay with upgrade and such like but not so much programming lark). What is this FULL_EDL package and how straight forward would it be for me to use it? Where do I get hold of it?
Everything is fine except phone call, sms and data of course. Internet connection is fine and all the apps works too.
Another question, would it help if I did a full factory reset and then applied the correct upgrade? I have backup of all my apps, contacts, pictures, music, etc.
Thanks

Not at all, this is much more messed up. A factory reset only wipes data, you need to fix a part of the system. If you are okay with unlocking your phone (i think you don't have warranty anyways) then you should do that, there are guides but be sure that they are FOR THE A2017!
After unlocking you need to install TWRP, those guides usually also explain you how to do this. Then you download this file and flash it through TWRP (put it in the phone, go to TWRP, Install - select the zip - swipe to start)
It may help understanding to know that there are 3 models.
A2017 is the Chinese one, A2017U is the American one and A2017G is multinational/European. There are different telephony frequency bands in use around the world and the Chinese one also has different storage and memory. A bit bummed they held that back from the rest of the world.....

Thank you for quick response.
Yes, you are correct, warranty is non-issue anyway and I will make sure it is for A2017 (not A2017G/U). Wish I had just checked the back of the phone then I would not have ended up here but it is nice to learn new things, however painful..
Thanks for the heads up on the process as well. There goes my weekend but the boss (wife) is away so it is okay.
I will report if I manage to get it working next week. Wish me luck.
Robie
Update.
I spent the weekend on this and sadly didn't get anywhere. I followed the instructions and download from here:
http://https://forum.xda-developers.com/axon-7/how-to/guide-b13-chinese-a2017-root-unlock-t3549873.
Unfortunately, no joy. I can get my phone in EDL mode (drivers downloaded & suetup successfully, COM port is correct, etc) but the following commands just sit forever. They don't respond at all.
axon7backup.exe -p COM# -d
axon7root.exe -p COM# -r
Not sure where to go from here. If anyone has any ideas then please let me know.
Thanks.

AT&T in Australia

Hi all,
Was recently in the 'States and broke my S8 - it's now the third mobile screen I've busted since Samsung brought in curved edges, never had any issues with the S2 or S5 - who ever thought tempering glass and curving it would be a good idea??
Anyway I had the opportunity to pickup a brand new Samsung Galaxy S8 Active and did a quick bit of research. I found the most compatible version with my carriers back home in AUS was the SM-G892A from AT&T. Picked up a brand new unlocked model, stupid me didn't connect it up to AT&T while I was there. I turned it on and played around with it on Wifi for the last few days of our trip and returned home to Melbourne.
Basically I now understand AT&T are a bunch of ***** and do not allow updates to be pushed even for unlocked devices overseas. Considering a lot of the updates are for security I'm very surprised by this.
Anyway so I've notcied a few tiny bugs here and there with apps/OS and figured updating my device/OS is the way to go and might resolve the issues. I guess the easiest way to get the info I need is to put the questions I have individually, as my mind tends to jump all over the place when I'm working a problem:
1. Is there any way to get my phone updated without rooting/flashing the phone?
2. If not, what is the best option for a S8 Active? Are there any firmware versions that will enable OTA updates so I don't need to keep flashing everytime new firmware is released? I have seen some posts about T-Mobile being able to be flashed over an AT&T model or even the G892U or maybe a custom firmware that allows this?
3. Will rooting/flashing interfere with any of the carrier settings etc? Don't want to upgrade it only to find it disables an LTE band or something?
4. I am an absolute noob at flashing, have never done it but am pretty tech savvy so if there is a step-by-step procedure I wil have no dramas following it. Saying that, I would rather not make the device worse than it is so I only want to follow tried & tested procedures if that makes sense, I don't want my device to be a lab-rat.
5. If there is no way to enable OTA internationally as per Question #2 when new firmware updates become available on XDA will flashing a new update delete personalisation/settings/files etc? Or will it retain them and update like a stock model performing a firmware upgrade would? If not, that would be a pain in the ass and time consuming to have to re-apply settings and reinstall apps every time and almost makes the idea of flashing unattractive.
6. I have baseband G892AUCU1AQG4 - taking into account Question #2 what is the best way to move forward? Considering Android 8.0 is available for the S8 Active and has been available for my model from AT&T since March 1st, 2018 apparently I'm hoping there might be some way to move towards that.
Hope someone might be able to help,
Thanks in advance
UPDATE 05/05/2019
Got some answers to my original questions...
1. Rooting/Flashing are different things - rooting allows custom firmware, flashing is the procedure to install custom or OEM firmware onto the device.
2. The best option for me I think is to just update to newer AT&T firmware so I get the updates and new software features as I'm not interested in custom firmware. I still do not know if it is possible to get OTA updates for this device directly from Samsung/Google.
3. As long as you are flashing from the same model firmware as in SM-G892A to SM-G892A should be no issues, however using SM-G892U might cause issues.
4. Once I wrapped my head around how baseband versions of firmware work and what is needed to get between bootloader versions flashing from SD Card or Odin (as I suspected) was very straightforward thanks to some of the guides out there. To make this easier for anyone facing the same issue I have written how I did this below.
5. Yes, flashing for AT&T will delete everything, it's an absolute PIA and that's why I will keep searching for a way to get OTA updates enabled if at all possible. However I believe Samsung SmartSwitch is pretty good for backing up and restoring so that might be a simple way forward.
6. See my latest post, I was 12 updates behind but able to skip 7 of them using my method.
I'm considering importing an S8 Active AT&T and have the same questions. How did you go?

Sorry for the slow reply I've only just had the time to dive into this. Yes I have figured it out.
There are two ways, incrementally update by applying OTA updates via the SD card. However trying to find all of these can be a pain.
The other way you may have read about is to use Samsung's own 'Odin' flashing software.
Because I had the very first baseband version G892AUCU1AQG4 I was way behind. The fifth-last digit designates the bootloader version, you cannot jump from v1 to v3 for example. So what you can do is use a few OTA updates to jump you from v1 to the first v2, you can then use Odin to jump you all the way up and use another OTA to get you to the next bootloader version. Hope that makes sense?
So I was able to use x2 OTA updates to get from 1AQG4 to 1AQJ2, then I was able to do one more OTA to get from 1AQJ2-to-2AQK3. Now if I was to continue using the OTA method with the SD card, I would need to run the process x8 times. This presents 3 issues:
1. Time consuming, trying to find all the correct OTA updates.
2. Even when you do get all the correct OTA updates you then have to copy each on to the SD card waiting for the phone to update and then repeat the process.
3. Even if you can find a link for a required OTA update a lot of the links are dead.
However using Odin and the flash files I was able to skip these and go directly from 2AQK3 to 2BRF2, use one OTA update and then I was onto Bootloader v3 (which is the latest version). Here is how I compressed 12 updates do into 5, good luck..
1. 1AQG4-to-1AQJ2 OTA (SD CARD): dropbox.com/s/ikor71zt1ec0nyn/SS-G892AUCU1AQG4-to-S1AQJ2.zip?dl=0
2. 1AQJ2-to-2AQK3 OTA (SD CARD): dropbox.com/s/ott9fs9qunkvf9x/SS-G892AUCS1AQJ2-to-U2AQK3.zip?dl=0
3. 2AQK3-to-2BRF2 Odin Flash : androidfilehost.com/?fid=1322778262904016415
4. 2BRF2-to-3BRG1 OTA (SD CARD): androidfilehost.com/?fid=1322778262904016441
5. 3BRG1-to-3BRL1 Odin Flash: mega.nz/#!7M42VCAJ!-FKnhzwTZG0He1kb9FzHHaPX4Aanlnj4fpn0M61DzR4
Have the s8 active outside of America and desperately want to update it
Hey ,
I'm sorry to bring up this old thread but I didn't really understand the method you used sorry I'm really new to this thing, I have the s8 active Sm-g892A ( the att) model it's on the baseband version G892AUCS2ARB1 . If you could help me out a bit with this I would be really grateful, having Android 7.0 really makes me concerned as I've heard the security patches also won't update.

So you are on Bootloader v2 (5th character from the right). So you can skip straight to Step 3. Be warned all instructions below will result in all data on your device being wiped!
Using Odin to upgrade as directed on Step 3 & 5 or future upgrades (there is now v4 software appearing):
You need to download Odin (you don't need a modified/Comsy version).
You need to enable Developer Options on your Galaxy.
Once you have developer options you need to enable 'USB Debugging'.
You need to shutdown your Galaxy.
Connect your USB cabble to your PC.
Boot into Download mode by using the Power+Bixby+Volume Down combo. OR if that doesn't work Use the Power+Bixby+Volume Up and use the menu to get into Download Mode.
Open Odin on your PC, it should say 'Added' if it detects your Galaxy correctly. If it doesn't you may need to install some USB drivers (you can Google how to do this).
Once it says 'Added' you can add the files from Step 3 and flash but be warned it will wipe everything on your device.
For Step 4 OTA:
Very simply download the ZIP file and place the complete ZIP file on an SD Card (it should not be extracted must be complete ZIP archive). Place the SD Card in the Galaxy, power off and boot into Recovery Mode Power+Bixby+Volume Up. Then simply use the Volume Up/Down and Power keys to navigate through, 'Apply Update from SD Card', find your SD card and the ZIP file and allow the update to run.

Noob looking for pointers to help with upgrade process

Hi. Been waiting a while to post this, and playing around based on what I see, but I the last change I made to my phone hasn't worked out too well and I don't think I have enough of a grip on the process. I am an ex-computer 3rd level tech support so I have reasonable skills around computers etc.
I bought an Axon 7 (A2017G) in Germany but it got flooded one day when it went down the toilet pan, literally. So I replaced it with a 128 Gb model from China, not really thinking about the software versions. Of course it came with A2017, and more importantly, no ability got OTA upgrades from Android 6.
So recently I've been having some battery life issues so I've changed the battery.
Following guides here, I've managed to get it onto a newer A2017 version and it has taken an OTA upgrade to Android 7. The build number is B13. The boot loader is still unlocked. But it's not very stable and Google Play service has now stopped, and I can't be doing with the unreliability. And tbh although it worked, I can't remember exactly which guide or what steps I followed to do it.
So I want to put it onto a stock G version, which I think seems to be possible, based on stuff I've read here. I don't think I need root going forwards (once this is done) and I'm looking for the simplest method. Unfortunately, due to the length of time it's been live, this forum really is information-overload and I've been reading for two days now and made loads of notes but I'm not really very clear about what I need to do.
I'm quite happy to find and read the right guides but would be really grateful if someone could take a few minutes to just tell me exactly which bits are essential to be upgraded and what steps I do need to follow. If I am confused I can come back with any queries.
I'd be happy to root the phone if it's felt that is a really useful thing but I'm not really a "power user" and I'm OK with standard.
Also I'm assuming any upgrade would receive any future Android releases OTA (if there are any for this phone), but if not that's not too vital.
Thanks in advance...
Geoff
But regarding your situation: You have an A2017 with A2017G firmware, right? Can you tell us your firmware version?
Would you be fine with Chinese firmware (MiFavor 5.2, B17) or prefer stock+ (G B01/B02, U B12)?
Thanks for the quick response, really appreciated.
The firmware is still A2017 version AFAIK, but I don't know where to check. If I go to the boot loader screen it says ZTE/P996A03_N/ailsa_ii and on the next line 7.1.1/NMF26V/20170912.013327
I'm thinking I'd do the change from A2017 to A2017G to get round the annoying junk which came with the Chinese version, and also avoid the Google Play Services problem I came across. It may not be do-able but I thought I'd read it was.
I guess in addition to telling me the steps, telling me exactly which file versions to use would help a lot. I promise to keep notes!
I don't mind which firmware, so long as it works reliably and so long as I can preferably put a G version on it.
of course it's doable, the thing is that you'll need to unlock the bootloader in order to.
If you had trouble with Play Services then it's most probably on chinese firmware, finding out would be as easy as going to Settings, then About phone
The boot loader is still unlocked from when I managed to do the previous upgrade. That took me quite some hours, and it was more by luck than judgement that I got a result. This time I want to better understand what I'm doing.
Not sure what I'm looking at for the firmware, isn't it the versions I quoted above? But the menus (mostly) are in Chinese at start up, and I had to load Google Play and Play Services from the ZTEYR store so I'm pretty sure it is on Chinese firmware.
So if it is, do I just need to upgrade the firmware then the ROM (is that the terminology?). If so which versions would I use?
Ta
Geoff
EDIT I missed the kernel version - which is 3.18.31
OK so I've spent more time reading. I'm coming to the conclusion that I don't need TWRP and I don't need to update my Chinese bootloader, does that sound about right?
Is it right that all I need to do is
- find a G firmware zip file <<< may have incorrect terminology here, would appreciate a pointer to a valid download as I have many but not sure they are the right type of file
- put it on an SD card named as update.zip
- boot into recovery mode
- choose "apply update from SD card"
And, assuming I have used a stock version, will it then update to the latest version (hopefully Oreo) once it's started?
Do I need to do any formats or wipes anywhere in the process? I already have a backup of my stuff, done with AXON7Toolkit.
And can you recommend a version of firmware to go to, or does it not really matter as it'll update itself anyway?
UPDATE: MiFavor UI is v5.0
OK, so there is no real short easy answer to this.
I've used the updates from ZTE since I've had the phone until I soft bricked it.
Zte offer updates similar to this.
Eg: B06 to B08 or B08 to B09 and B09 to B12
The update has to be done in stages.
Some updates you can copy to the internal SD card then go settings > system > update, your phone should detect the updates and tap install.
Some Zip files can be done the same way after changing the file name to update.zip or Ota.zip depending on the instructions.
Some zip files have the update within the Zip so it needs to be extracted.
Make sure you have the correct version software and correct version for your phone.
After the update is done all the data etc will be still in place unless you reset your phone.
All I can say is research, research, research.
Btw if your bootloader is unlocked some updates will fail.
I hope this helps
PS: you can use the method you described as well, just follow the instructions carefully.
In most cases there is no need to wipe or format unless you are using a custom ROM etc.
Excellent, thanks.
Going back a post or two - I re-installed Google Play services but still have problems. Before a reboot it appears in the list of apps, and Play opens, but the sidebar comes straight in and behind there is a message "Error while retrieving information from server [RH-01]" . After a reboot it is no longer in the list of Apps (even when expanded to include System apps), and Play just opens and closes real quick.
So I found a thread which led me look in Settings in Play Store at the Play Protect Certification, which says the device is not certified. So I downloaded the related app and ran it, which gave me a code which I put in web page then entered the stuff into my phone but still no joy. I suspect this is causing the Play problem and I think it'd be due to trying to use Google product on a Chinese firmware (again I'm not sure my terminology is right - I mean whatever the software is which throws up the initial boot screen).
So I think I need to get off the Chinese firmware at the same time as going to a G version, and I'm even less clear on how to replace the firmware than the rest of the process - what files and how it's done.
Going back to the more recent post (Syberclone), as I have already wiped my phone I'm not concerned about keeping data. I understand about doing this is steps - I hadn't thought of doing it that way but it seems very sensible.
I found a post by Raystef66 with loads of links to software - including A2017X_B15_Universal_Bootloader.zip. Does this replace the Chinese firmware and would it work with all zipfiles? How would I apply it? (I was using Axon7ToolKit the other day and that looks quite impressive).
I am still confused over the different types of files and the naming conventions but it's slowly making more sense. Appreciate all advice.
Thanks
Geoff
Personally I use Edl packages much easier imo.
I use Miflash or Edl tool by @djkuz
I have a bad flash help page that explains the process.
The bootstacks etc are mainly for custom ROMs, if you are just looking a factory firmware, Edl's are much easier to install without worrying about bootstacks, twrp etc.
My last Edl update was from Nougat (Chinese Rom)
To Oreo A2017G I had to factory reset after the install though.
Thatnks. Today I've done a fwe more hours reading, literally. This is taking all my time!!
Anyway I decided to follow your advice and found a full EDL of Oreo, which I applied. (ZTE_A2017V3.0.0B17) and the phone is still working, and I've not lost my apps.
However I still have the problem that Play Services won't run. I've upgraded it, followed a few troubleshooting guides, used different versions ( - should I be using the 64 bit one??) but still no joy. If I could only get that going I'd stick with the Chinese firmware. It is looking to me like it can't sync, though whether that's a cause or an outcome I'm not sure. Not unexpectedly, a number of apps will not run as a result.
I haven't done a factory reset yet, I thought I'd ask here first to see if that is likely to fix it or whether anyone has any better ideas.
Despite the time this is taking I'm enjoying learning and am grateful to you all for the responses.
The play store link "device not certified" will happen when you change a ROM from its original.
So I have an A2017G, when I run any other ROM it will show "device not certified" because the link between the phone and the software isnt in sync.
When I was running the beta Oreo from the Chinese my device always had this issue and NFC does not either usually.
There is a play store app version which will work as it should however the certified is still a problem without a work around.
When I installed the G version Oreo to my device the certification is back.
I'm miss some of the Chinese ROM animations tho.
Anyway I hope this helps
I am using an A2017 ROM on an A2017. I've not changed anything else. Maybe I need to update the boot stuff (firmware?).
What I'm seeing is that Play Services always needs to be manually enabled, and seems to drop out and require re-installation sometimes. So I have an apk on my internal memory for quick access.
I'm not sure that the "device not certified" is a cause or effect really.
So I have an apk on my internal memory for quick access. It's the latest non-beta 64bit version for Android 8 - should I try a specific one, e.g. is there likely to be a specific one which matches the ROM? (An older non 64 bit one seemed to give much the same problem)
I'd put up with the problem except I can't run some Google stuff at all (Play Store for instance), and some other stuff is compromised (e.g. I can't get into Waze on my usual ID, I'm guessing Play Services plays a part in authorizing). And I can't install some stuff I'd like.
And I'd still be interested to know which bits require upgrade to go to a G version, if it is do-able and would run trouble free.
There was a play store app that worked on most ROMs.
You are on Oreo now yes?
There was a link on one of the Android pie ROMs that I used, it worked fine.
If you are still having issues you can use an app called Yalp that works like the play store.
I've used it on custom ROMs when the play store app refuses to work.
Yes, Oreo now.
I've put YALP on and that looks pretty good. I now seem to have most things working, and those that aren't I can probably live without.
I use a network tool called FING which reports my phone details, and I think it's incorrect but it's saying in one place it's a A2017U which I don't think is right. But now I am more comfortable with EDL and stuff I'm going to continue to fix this properly but the urgency is now not there. I was thinking if I couldn't fix this I might have to buy a new phone on black Friday!! So thanks for your help.
I'm still not really quite sure why I get Chinese characters at start up and what files I need to change to out a G firmware on, if that is what is wrong, and if it's do-able. I think if I knew how to do that then I could put on a G firmware and matching ROM and I'd be in business!!
The same page offered me F-DROID which seems to offer a whole load of different free apps. Maybe they don't have ads? Anyway I'll have a look.
Anyway, again - thanks!!
Geoff
Geoff I'm glad I could help
I was running the Chinese Oreo on my phone and after selecting English in setting some parts of the ROM were still in Chinese, even some notifications.
I converted to the A2017G Oreo update when it was released.
I miss some of the features in the Chinese ROM tho.
So... without wishing to prolong this... your phone was Chinese (as mine was) and you are now running a Global version and all you upgraded was the ROM? And are you able to use the Play Store and you don't have any issues running apps I - and can you run, say, Google Maps?). Is your bootloader still unlocked and if so is the menu at boot time still in Chinese?
Or have you upgraded something other than the ROM?
I actually have an Axon 7 A2017G here in Australia.
I soft bricked it when I accidentally made a mistake flashing a ROM.
I searched for a suitable stock firmware but I could only flash the Chinese Oreo Beta. It had to be modified to run on my device until the Oreo package for my A2017G had been uploaded.
I've now running the proper software for this phone.
Thanks.
Another couple of hours and I have made a Major breakthrough! I went back over all my notes and checked what i'd done and one thing I hadn't remembered doing was setting the Pay Store to Autorun. So using the Mi-Assistant I have done this, and most of the stuff which wasn't working now is. I am still working on why OK Google won't work, but the list of things I might have to live without is now quite short!! The one major benefit is that my battery life seems to be greatly increased. Boot time is also much quicker which is a bonus but not critical.
Nice, yes battery life is improved, actually the Chinese Oreo Beta has a better battery life than my current Oreo.
I could get up to 4 days out of the Chinese ROM, my current ROM can manage just over 3 days at best.
I have battery saver mode on but not ultra battery saver.
I hope this has been a good learning experience for you?

For sure it has. Back in the days when I was 3rd level computer techie, the best learning came from other experts and from being thrown in the deep end, rather than what they taught you in the classroom!
