Update zip but the first question is what update zip .
Usual zip files install via CWM clockwork mod recovery .
Boot to recovery install sdcard/update/zip.

You need to have 2E recovery working on your phone in order to install unsigned update.zip files, either check your phone for the 2E recovery by going into 3 button recovery mode (switch phone off, hold volume up, home key and power button until logo appears on screen and let go of all 3) and the screen will say whether you have 2E or 3E recovery mode or here is a link to Chanfires excellent kernels which include 2E recovery but you must flash them with onto the phone with Odin. I'm not too familiar with the i9000t so you had best do some reading up first to make sure it can be done with your phone as you could brick it if the kernel is not for your unit.
Once you have the kernel flashed onto the phone or you have checked and already have 2E recovery, simply make sure the update.zip file is on the root folder of your internal SD and select the install update.zip option in recovery mode (you get into this as described above)
I have tried everything in my toolkit to get the Dexter Mod installed on my A7...the new firmware update worked fine, but when i follow the steps for the Dexter mod..in recovery mode, i get a message that says:
Install from sdcard
Finding update package
Opening update package
E:Can't open /sdcard/update.zip
(no such file or directory)
Installation aborted
Formatting MISC...
I even downloaded the Dexter Mod from my computer at work yesterday and brought it home to try to no avail...
Why isn't this working?
Is there another place I can download the Dexter Mod 11 from to get a different file..
How can I be sure I am in the root directory of the sdcard?
I realize i am brand new at this, and i am willing to do the work, but really I am disappointed the the mod will not install..
also, I noticed that when I ran the firmware update, a few programs that I had downloaded were erased...how do i back program up on the A7 so they are not lost
Another question
Is in necessary to install the previos Dexter mods before the 11?
No, you don't need to download the previous ROMs first.
Your download may be corrupted. That happens a lot with large files.
This one is over 90MB.
Getright is a free download manager that helps with this issue.
Get it here:
http://www.getright.com/
Try that and let us know if it works for you.
I installed update.zip from the root directory of sd card (nothing on sd card except Update.zip), from within settings> about> update firmware.
It will go through the steps and boot loop.
U then hold off for 15 secs, then turn on for 3secs, let go and hold till it says > loading boot kernel ( recovery mode), then wipe cache and settings.
Done!!
Whew.
when renaming the file leave out the zip part. i was having the same problem . if you noticed the elocity update doesnot name the update w/ zip at the end
thank you
Hi guys. M currently usimg Nephilim Rom V2. I was trying to flash b594 stock rom. Whenever i tried to install it with stock recovery it just says no update.app is found. Even though i extracted the update.zip file and put it in internal storage in dload folder. I cant even flash it through fastboot because it gives error even though i extracted the img files through Huawei extractor. Can anyone help!!!!
What kind of error fastboot method gives you? I always have went back to stock rom by flashing a rom in fastboot and never had problems with it
While flashing system.img i got error cant load system.img. even though it's in the same folder as adb is. There was also an error whule flashing recovery extracted from update.zip. i was flashing the recovery.img only and it says errot:too many links.
Try to re-download your adb and its related files

Done that to same result...
So you want your original firmware correct ? If so , go here: http://consumer.huawei.com/nl-en/support/downloads/detail/index.htm?id=82749
Change region (if needed) find your phone and download that.
Once you downloaded it:
1. put it on your sd card
1.1 Since when you download the file, its gonna be in .zip or .rar format, you are gonna need to extract that and what you get out of that file (its gonna be a folder called dload) put that whole thing "dload" on to your sdcard. ( put in in a main folder of your sd card its called root folder, its where your main folders are like pictures, DCIM etc.)
2. turn off your phone leave it for a sec
3. then hold all 3 buttons ( power ,volume up , volume down) and it should start installing the thing.
Hope this helps.

Are you able to install stock recovery through adb? If you are, you can easily use Huawei's recovery to flash the stock firmware

Ahh, sorry, I meant to say that you could try after flashing stock recovery to use EMUI updater to start the flashing.. anyway good that you got it to work
Hello,
I tried to flash the RessurectionRemix ROM and it was working well except the LTE so I decided to get back to EMUI.
Problem, i took the backup of bluesmoothie and flashed it but the phone never finish to boot.... (I didn't wipe anything, i thought that the restore function of TWRP was doing everything, am I wrong ?)
Moreover, the TWRP recovery can't access the content of my ext sdcard where the RR ROM is located and even if i put this rom to internal storage, i got the ERROR 7 (this is for deive: can; you have generic_a53)
Do you know what can I do to :
- Come back to EMUI
- Unroot the phone
- Re-lock the bootloader
The files of the TWRP backup are located on the sdcard, if i wipe data/system/cache, will it delete these files ?
Infos :
- Bootloader unlocked
- TWRP of Garak (but still have ERROR 7 now)
Thank you very much
First you need to flash the stock recovery in fastboot. After that you need to put the update.app in a folder called dload in your internal storage.

Okay but where can I find the stock recovery ?
Then, do i have to flash it via ADB like i did with TWRP ?
After that, where can I find the "update.app" that you are talking about ?
If i'm right, you're telling me that i can't go back to EMUI without flashing the stock recovery ?
That is correct. First use firmware finder to get the update.app. There is a firmware extractor tool for Huawei firmware. Use it to extract the recovery.img and flash with fastboot.

First of all, thank you very much for your anwser, it's very kind of you.
If i understood everything, that's what i have to do :
- Download one of the Huawei firmwares with Huawei Finder (Better get the B100 or another one ?)
- Extract the recovery.img with the update.app from Huawei Finder
- Flash the stock recovery with ADB
Then :
- I put the update.app that i get through the Huawei Finder in the dload folder of the internal storage (If i flash the stock recovery, will I be able to put files in the storage ?)
- I reboot the phone in recovery and normally, it should install the EMUI rom
At the end, my phone will no longer have a custom recvery, bootloader unlocked and root status ?

Yes, that's correct. But you have to put update.app in dload folder on your SD card as far as I know. That's how I did it.
I couldn't find B100 on Firmware Finder and I've got relocked bootloader on Nougat.
Yes, you will need to copy the update.app to internal storage in TWRP, then flash the stock recovery. After flashing you need to hold all three buttons when booting (just like getting into TWRP. After update you will have no custom recovery, no root, and it should lock bootloader.

If it doesn't boot, then boot in recovery and do a factory reset and then it should boot. It happened to me and that's what I did.

When i boot into recovery it's displaying "eRecovery" and ask me to download the new update of recovery but it fails when getting the package. I can only reboot and turn off :/

You shouldn't have that message anymore.
Are you sure that the update.app got installed? @wangdaning told you to put it on dload folder in internal memory. I don't know if that is right or if it works, but I've put it in dload folder on sdcard when I've installed update.app.

You can read in this post the steps I've used to relock the bootloader and get update (official I guess) through Settings > System update. Just "click to show content".

The problem is that the phone doesnt finish to but anymore... i can't do things in menu.
When you talk about SD card, it's the external sd card ? Because i don't have access to it anymore, but i have the partition SD Card
When you installed the B340 update, you seen the percent growing up and had a "success" message ? Because, for me, the update is stuck at 5% and then it reboot the phone

Yes, I mean external sdcard.
Reinstall TWRP and restore bluesmoothie's backup and then flash the stock recovery again.
I didn't have any issues with installing the B340 firmware. It was installed successfully.
Try to follow the steps I've used. You shouldn't have any problem.

Okay i'm going to try it right away
My external sd card doesnt show up anymore when i connect it to my PC, i don't know why
I mentioned internal SD card because you said your external was not recognized, but you might try putting the dload folder on external. I have done it both ways. Sometimes the update through stock recovery is finicky. If it doesn't finish run it again. Also, make sure your USB is disconnected, as may Huawei users have mentioned this causes it to freeze. If it still fails, try dloading a different update from firmware finder.
Did it work?
I didn't have so much time these days but I did it and it worked for the 1st part (flash bouesmoothie's backup). Tomorrow I'll do the final step! Thank you again
Here I am :
1 : flashed stock recovery from B350 and i don't have the "unlocked" message anymore !
2 : The update B350 made it, "update success"
3 : It doesn't boot for now
4 : The boot doesn't end
-----
1 : flashed TWRP recovery, launched a factory reset in the same time
2 : Phone booting again on B100
-----
1 : flashed stock recovery from b350
2 : flashed b350 update
3 : Everything is fine !

Hello,
i bought my Axon this week from Amazon Warehouse.
My problem is, that im not able to update my ROM.
I tried OTA, Install over Recovery (SD-Card), Install over Recovery (ADB Sideload).
All methods failed..
OTA is downloading the update, rebooting and than crashing. Hard to tell why, because i dont see any error logs. Just the information "Update Failed".
Next method i tried was to install over SD-Card. I downloaded the Update from ZTE, moved to my SD and tried to update. But my Smartphone always tells me "Couldn't mount /sdcard".. I tried to Format it with extFAT and FAT32 but both failed.
The last method I tried was using the ADB Sideload. I tried it with the update file, and also with the STOCK-Rom from this site: https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547. But also i get an error message.. ADB tellst me "Total xfer 0.00x"...
Have i bougth a bricked Axon? Can I update somehow to the new version?
I have the option to send it back to Amazon, but it was 100€ cheaper, so i would love to fix the problem.
Kind regards,
t4ggno
Recovery stock and SD card seem to be the most reliable method.
Did you check the md5 of the zip? Also update.zip to put on root of the SD card should be the final zip, not the zip that contains another zip.
Also when booting in Android, I assume your SD is recognized, isn't it?
If so, instead of going to recovery then update from SD card, you can try to update from inside Android, from Phone settings, then Update item.
The phone should indicate the current version and the version to be updated to. Then follow the phone indication to update.
Nope, i dont checked MD5. But shouldn't be the problen. I tried many different update files, always same error.
Yes, after booting the SD card is connected and i could use it. Just the recovery mode cant mount the card.
Also the updater recognize my update. But he just boot in the recovery mode and try to update -> Same error: "couldn't mount /sdcard"
Edit 1:
But i can check the MD5 files if necessary. I just need the "correct" MD5 value to compare.
Just a guess:
Is your micro SD card size greater than or equal to 128 GB? Some version has this bug, size less than or equal to 64 GB should work better. To try if this is the case.

Why are you using an SD card though? Put it in the root of the internal storage and it will surely pop up, then try again from Updates, not the recovery (and get the SD off the phone to avoid the phone from detecting the zip there)
Otherwise root and get TWRP and flash Tron1's stuff

I don't know where you read that, but the closest answer that I can give you is: if you don't install SuperSU, Magisk, or the dm-verity patch, TWRP will get replaced with the stock recovery and you'll have to flash it again (~2 minutes anyways). But it is in no way incompatible. Also you can relock and stuff, but yeah better keep the warranty at least until you're sure that your phone is good.
You unpacked the zip that you downloaded right? to get the update.zip inside? Or did you download it from raysteff's thread? It should work anyways
Another thing: What is your phone's model (G, U, chinese) and what is the update that you're trying to install? I guess it will fail if it is from another model, and if you're trying to jump fron a very old MM build to a very new N build it will probably fail too. Keep that in mind.
First, what is the version of your device?
I'm guessing you are using a chinese device with modified rom. Those units can't install updates unless you first restore to original chinese rom.

I have a A2017G (that information i found on the back of my phone).
My phone overview tells me:
Modelnumber: ZTE A201G
Build-Number: ZTE A2017GV1.0.0B08
Android-Version: 6.0.1
Security-Patch: 1. December 2016
I can try to install the B09. Probably this patch is required to go to version 10 (and than to nougat)?
Don't know if it applies to your situation, but when the OTA for 7.x came out, there was a bug that would not allow the update to be applied if there was an SD card installed. I know I had to pull my card to get the update to take. Might try running the OTA without the card installed and see if it works.

No, B09 was a patch only for Spain.
The zip you download from the ZTE website has a bunch of numbers as name and has an update.zip inside and a PDF or sth like that. The one you have to flash is the update.zip inside, just sayin'...
If you download the zips from raysteff's thread they are already unpacked.
Try installing an older zip, like B03, then B10

The big problem still exists -> I cant mount my SD card in recovery mode, so I cant install any patch.
I really want to try B03 as you suggested, but i am unable to install it.
I will search another SD card an try to use it. Probably my SD card has some problems.
Edit: I download my files from these side: http://www.ztemobile.de/support/downloads/?product_id=2100
They dont contain a update.zip. Only many .dat, .bin, .img and .mbn files.

But install it from the internal storage and with thr Updates option on Android itself... You need to put it in the root of the internal storage or it most likely won't find the zip

Thanks! That worked very well. I did a factory reset and moved the update file directly to the root of my internal storage. After that the updater detected my update and I could install the Patch B011. After that i was able to update to Nougat trough OTA. No errors, every worked fine.
