Stock recovery extraced from BTV-W09C233B019 ROM - untested - Huawei Mediapad M3 Questions & Answers

Hi M3 users,
I'm a long time lurker and reader on XDA. Now it's time to give something back or at least participate
Following my recent M3 purchase a dugg a bit deeper into this topic and tried to get us the stock recovery for our devices.
I'm not really a dev. I just used the information I found here and in the russian forum where greatslon (thank you guy) is posting his work.
If you find an error in the process please let me know. The files have not been tested in any way. I have no idea if this would even work (encryption and so on).
So I managed to extract the recovery.img file from the chinese rom. This method will also work for the LTE variant.
Maybe @greatslon or @somboons can share their view on the topic or maybe @somboons can even use it in his tool.

Don't quite understand what's this for. First of all, recovery should be the same version as your ROM. I don't know if their mismatch will immediately lead to some malfunction, but some people on 4pda said they should match. Second - stock recovery's functions are limited to factory reset (wiping data, cache, etc.) and installing OTA updates. Without changing OEMINFO (and it's still unconfirmed), you won't be able to install any OTA except those, intented for your model and region, so again there's no need to install a higher version of recovery than your ROM is. But anyway, thank you for the extraction instruction.
P.S. I think there's no need to flash both recovery and recovery2. Recovery2 can be successfully replaced with TWRP and this combination is really great, cause you can launch TWRP by holding Volume Up button only.
And the only reason why you should keep recovery original is that it doesn't really wipe /data - it also creates some files there like custom.bin, containing your regional settings.

Hi Slavon,
Thanks for your highly appreciated comment. @somboons was looking for a stock recovery so I thought this might help.
Your given information are really helpful. I did not know that you could flash TWRP in recovery2 and replace erecovery Handy information.
I'm pretty new to the Huawei structure so always glad to learn something.
EDIT
A lot of good information can be found here: http://forum.xda-developers.com/honor-7/general/dual-recovery-honor-7-t3308398
Thank you very much,

Giving Back
Benjamin,
I've also been a long time XDA lurker. Most of the devices I have owned were mainstream and thus already had a very active XDA developer community; Even if root had yet to be achieved, there would be hundreds of messages on the topic.
It seems the Mediapad M3 is just getting started. I am a developer of over 20 years, but very little android experience. However, I have recently spent a considerable amount of time (about 50-100 hours) working with the low level ADB protocol source code. And I have rooted and flashed no less than 50 devices, everything from cell phones to Android TV devices to routers.
I'm going to take this device on as my first real dev effort in this arena.
I have a few goals:
1. Get working backups for people that soft-brick or need to revert (including myself).
2. Recompile TWRP for the M3 to confirm greatslon's work, and better understand the process.
3. Release a stock rom that's pre-rooted and cleaned up (not that there was a lot of bloat on my device).
4. Release a custom rom that's not MIUI (perhaps based of CyanogenMod).
Since I have virtually no experience, I am sure these goals are quite lofty and will take some time. But hey, you got to have a plan, and I don't have anything else to work on right now.
Let me know if you want to work on anything together, or if you need any help with anything development related.

Hey hey 0D0A,
I totally agree with you regarding the backups, I think once the first OTA update is pushed for the EU and US devices we have a good and safe way to go back.
Especially the US owners are struggling with greatslons TWRP version, that's the first thing we should tackle after the backup topic is cleared
I will contact you regarding possible work
Best regards,
Benjamin

can flash twrp via fastboot but get error saying and no recovery
hi, first thanks greatslon for doing the work on m3.
i seem to have succeeded in getting stuck and can't get it to boot into your custom twrp. adb on linux was working fine, but no longer. ditto for fastboot just get "waiting for devices" now. i switched to win10 and installed the hisuite app so i can use fastboot but still no adb. so i have tried to flash recovery and recovery2 but when i try to boot recovery i get error "Func NO: 11 (recovery image) ERROR NO: 2 (load failed)."
i then downloaded your custom rom and tried to flash the boot for that still no luck. i can't use adb so i am not sure how to just flash the custom rom with fastboot without being able to get into any recovery.
i did have this all rooted and working with your twrp but kept having issues with dpi and there was an ota update (b003) which wouldn't apply. so i tried to restore backup and it wen't south from there. basically now can't do much other than see the unlock "can't be trusted" page and bootloader.
any suggestions?

Desperately need stock recovery img, not sure exactly what when wrong, but it is stuck in a horrible boot loop. Tried Benjamin's recovery files and they seem to remove twrp and put it somewhat back to normal, but can only access the emui recovery and that fails to load the files. Put twrp back and tried greatslon's ROMs, they load but goes back to boot loop. Wipe and format everything, install my original backup through twrp recovery, it says it works, but again, back to boot loop... at this point I think I'm dead... any ideas, any word on the official recovery img? anything? Help!!

What device do you have? And what version were you on?

Hello, I am unlocked, TWRPed, and rooted, but am trying to reverse all of that. My build number is BTV-W09C128B002. Is it safe to download the stock recovery from the OP for my device? Or do I really need the C128 version?

Hello and sorry for the late response, you would need the matching version for your C128 device.
I may be able to extract recovery from an update, I have to look into this tomorrow.

Thanks! I have been able to use the Huawei Extractor to extract a recovery.img from OTA updates, but have been afraid to try flashing it. It has been recommended to hold off on trying that since that recovery.img is from an OTA and not a FULL update. Any thoughts?

[HELP] Need Expert Help! Asus Zenfone 5 LTE (A500KL)

First of all, I wanted to apologize if I'm posting at a wrong section but please do move this thread if necessary.
Second, I know some of you have already read a bunch of problems regarding to this model of zenfone 5 but I'm still hoping that one day someone can help us A500KL users. I've spent sleepless nights browsing the internet for solutions. I've been through different websites like taiwanese, chinese, russian and many more but still can't seem to find any guides or solution to my problem.
The thing is, one day after booting my phone and making it to home screen a few seconds later it's restarting on it's own. restarted and same thing happened over and over again. I didn't mind losing my files so i went to recovery to do a factory reset hoping it will resolve the problem. But the moment I press enter, a bunch of errors saying E:failed to mount...... (invalid argument) showed up. It failed wiping to factory reset. i tried wiping cache but still gets a bunch of those error. I know little about flashing so I came to a place where they said that i have to download the stock firmware from asus website with the same version and same SKU. so i did that and stored the stock rom on my external SD card (can't save in internal since I can't boot to homescreen anymore. Just ending up in Asus logo loading forever.) but still no luck. I Searched some more and found a guide about flashing using AFT. I tried but still no luck, says it needs a .raw firmware. unfortunately anywhere i go there is no .raw firmware for my phone. so I explore some more and came across about bootloader. but recently i found out that my bootloader is locked. Neither can I flash using sideload.
My phone is not rooted, no custom recovery installed, no option to install update from ADB and can't install from recovery. BUT still able to go to recovery, boot until asus logo, when charging battery icon still shows. still vibrates when powered.
I really hope someone out there can help me with my current problem. I still think this can be done cause i don't think theres a problem with the hardware. Been searching for days and I really need to recover my phone. Oh and not to mention there are 2 more of this phone on my relatives and all of them have the same problem. So please help us A500KL users. Sorry for the long message, I'm just so desperate to recover my phone. God Bless
hi bro
well firstly bootloader unlock is NOT needed for sideloading stock firmware.i'm giving you the link to one of my tutorials,follow the procedure carefully.note one thing that do NOT download the firmware whose link is given in tutorial,instead use kitkat firmware of your phone(download from asus support page)....use only kitkat firmware pls.coz my experience says that flashing lollipop directly gives errors.http://forum.xda-developers.com/zenfone-5/help/bootlooped-bricked-returning-to-stock-t3358662

That method only work for A500/501 cg models. Not A500KL .It will not work. I already came across this problem. There is NO RAW FIRMWARE FOR ZENFONE 5 LTE

Hello bro.. your tutorial is well said but unfortunately Zenfone 5 LTE is different. Yes i do have a firmware downloaded at the official asus website and it doesn't contain any recovery.img and fastboot.img there's only boot.img inside. and yes its only kitkat. its WW 11.4.6.94
Lastly, zenfone 5 LTE doesn't have "apply update from ADB" option in recovery by default so sideloading is not really possible. I can only depend on fastboot with locked bootloader. so yeah that makes things difficult.

You din't get what i mean.... His system partition is MESSED UP. The partition also contains fastboot and recovery partition. Flashing fastboot and recovery WILL FAIL. He will have to find AND RAW FIRMWARE NOT A ZIP FIRMWARE FROM ASUS.
I already searched for Raw firmware for zenfone 5 lte. There is no raw firmware for that model. Using that guide requires the raw firmware. In the process that tool will use the RAW firnware to fix the partition table.
Hopes that clears everything up
Hi Bazerald,
My 18-month old A500KL has exactly the same problem as you had described - startup never get pass the Asus logo screen, got a bunch of "E: failed to mount ....." error messages in Recovery. I was told by the Asus Service Centre technician that the problem was caused by a broken ROM and to revive the phone, a replacement of the mother board was required and they were charging megabuck for the job. I ended up taking my phone back without fixing and here I am browsing in this forum hoping to find an alternative solution.
Since I know everything else on my A500KL is still working except the internal ROM, what I am hoping to do is to find if there is a way to load the stock firmware onto an external SD card and boot up the phone from there, in other words, I would like to swap the internal and external memory. I can find a few discussions on this topic for the Samsung Galaxy, but I have yet to find a viable solution for our A500KL.
Any member has any suggestion on this idea?

I agree, I was hoping for the same thing here since xda is very popular for fixing tons of problems. I guess we'll just have to wait for THE ONE who can help us.. since A500KL doesn't seem have a raw firmware I'll be very happy if anyone can spend a time and make a raw firmware for us (if it's possible). Recovering the 3 A500KL here will be very rewarding.
Also, I'm trying to not depend too much on the raw firmawre cause the main reason is the messed up partition. Still searching for a way to fix it manually and getting some ideas on how it is done on other phones.
Unless you guys found a RAW firmware for the LTE model. It's preety much hopeless. Sorry........
does anyone know if repartitioning the messed up partition of A500KL manually is possible?
I got the same problem a few months ago. I searched through the Internet and found that many many people having such problem, I concluded that it is the quality of the chips (usually 15 months of usage), not software problem alone (the phone just died suddenly, I did nothing at all!!). This was the first time I had hardware failure in phones (in the past 20 years!). I WILL NEVER BUY ASUS phone again.
Ok guys, give me a sec and i'll find the firmware. Theres one on the website thats a revert firmware that will fix it. I had the same issue with mine. This firmware will revert it back to Kitkat. Yes.. Its DOES have the stock Recovery,Boot.img and System.img files.
This is the firmware your looking for Version WW_11.4.6.94 (Downgrade Version)
http://www.asus.com/us/support/Download/39/1/0/6/8/
ONLY FLASH THAT VERSION! Only Version WW_11.4.6.94 (Downgrade Version) (WorldWide) Version..
Only the Downgrade Versions have the complete files needed to repair a bad flash or root attempt.
Follow the directions Vaib posted on the previous page, but use the firmware file above.
Should fix the software,recovery and partition issue. Also, the bootloader unlock provided by Asus is hit and miss.
I've used it to root,but alot of the files are interlinked. So you run the risk of another app not working when trying to debloat the rom. As of now there is no Alternate non Stock Rom for the A500KL. Note: After flashing the WW firmware you phone will be recognized as an Asus "T00P". This is normal and doesnt cause any issues.
If all else fails, go here for more info on the A500KL. http://www.asus-zenfone.com/search/label/Zenfone 5 LTE
Good Luck. Happy Flashing

It should have, unless i accidentally linked to the wrong one. Let me see what happened.
The downgrade version should have recovery and fast-boot. It kicks it from L to KK. Since the fast-boot and recovery aren't compatible from L to KK, it should flash it. When i boot looped mine trying to a flash an alternate recovery i re-flashed using the downgrade version to fix it. I guess possibility that it could be in another WW Version, but im pretty sure i remember flashing the first WW Downgrade. I'm going to look at WW_11.4.6.71 and see if it in there.
OK, WW_11.4.6.71 has a script to install recovery. So the recovery.img is in the firmware somewhere. Try WW_11.4.6.71 instead and see if that fixes it for you.

The recovery isnt exactly named recovery.img, there's a script that refers to installing the recovery from another location. So i'd try flashing the downgrade version after getting the phone into fastboot. And unfortunately it can be difficult to tell if the phone is actually in fastboot.

ok thanks , will try it later on.
Wow.
You people really didn't read the comments section throughly.
Trying normal or downgrade firmware will not work.
This procedure requires a RAW firmware.
And using the offline update tool provided by @dgadelha.
If any of you found a RAW firmware for the A500KL model.
You can easily adapt the script from his Offline update tool.
It will repartition the device.
AGAIN. trying normal firmware is not going to fix the problem
@Bazerald (i think that your a500kl is WW) Try: with stock recovery try wipe the phone (data, cache), flash the firmware downloadable from asus site UL-ASUS_T00P-WW-11.4.6.94-user, (not the downgrade version), if not success, try UL-ASUS_T00P-WW-12.4.5.22

You'd think with all the other posts about problems there'd be something here by now.
Always thank those who are helpful...and just ignore those who aren't.
Mine happened when I wiped Internal storage from twrp. This caused the phone to only see 4gb of internal storage. Came to xda and it was suggested to flash back original boot.img. once that was done 4gb issue was fixed and the radio was gone.
I did indeed try every solution offered (thanks again for all the effort, DrakenFX and others). But, I've come to the conclusion that this is not going to get fixed until XTE releases US images. For other people's sake I hope I am wrong, but I myself decided to proceed with the exchange where I bought it, as I was right at the end of my 14 days (newegg doesn't seem to give the 30 days that xte does). I may be out of an Axon 7 for a while, so for now I am on my amazon ads, Blu R1 HD (with ads defeated
Is there a guide to go back to stock for the A2017G?
i'm on B02 with root and the bootloader still locked.
Like to go back to stock now that ZTE is working on an update to give the A2017G an unlocked bootloader.
Hi all,
I am currently experiencing a bootloop on my Chinese Axon 7. Some of you regulars may have seen me asking in other threads because I've tried to fix it myself, but I've kind of run out of options. Sincerely hoping one of you can help me out!!! I'll buy the winner a beer or 2, haha!
Back story:
Was on B07 with root (tenfar's tool) with locked bootloader and had some issues with the ROM. Like vibrating when I opened the camera and battery drops. So I decided to upgrade to B09. Placed the OTA on SD card and went to: Settings -> update. Worked fine. So I connected it to my PC and made a dump (tenfar's dump tool) of my recovery and boot and stored them. Then I ran the Tenfar's tool, the B09 version and it went like the last one. But when I booted I didn't have wifi, and other issues came up. So I thought: did I make a mistake? So I read it again, checked the COM port again... all checked out. And used Tenfar's tool again. After that it didn't even boot anymore! It plays the nice boot animation and then gets stuck on the end screen with all the pictures.
So after that I restored my dumped recovery.img and boot.img. This is when I knew something was wrong: it still didn't boot! I reset data/cache in the stock recovery: no boot. Still stuck at the end of the boot animation.
What I've tried:
- Flashing the stock B09 update.zip with TWRP.
- Flashing the stock B09 update.zip without updater-script 'assert' and 'get-prop' line. TWRP says 'update.zip is corrupt'. Doesn't install.
- The I put it on SD card and internal memory and tried updating it with stock recovery: 'sorry you cant sdcard upgrade'. That's all it says.
- ADB sideload stock recovery: 'cannot load update.zip'.
I tried different ADB versions, Windows and Mac, different drivers... I tried formatting SD card as FAT32.. Tried different SD card.. Doesn't make a difference.
TWRP log says it can't pass the Zip verification when I try that. If I turn that off it says re.product.name is wrong. But I checked build.prop and updater-script. It's the same! But somehow TWRP comes up with a different one. Also tried removing getprop and assert lines from updater-script. But then it says: ZIP file is corrupt.
TWRP log after trying original, stock B09 flash:
http://pastebin.com/cJivE2TK
Build.prop: moved from /system with TWRP:
http://pastebin.com/b6rryc2n
Build.prop: ro.product.name=P996A03
Updater-script:
Code:
getprop("ro.product.device") == "ailsa_ii" || abort("This package is for \"ailsa_ii\" devices; this is a \"" + getprop("ro.product.device") + "\".");
assert(getprop("ro.product.name") == "P996A03");
But TWRP log: ro.product.name=cm_ailsa_ii
So, yeah, I've been trying on and off for the past couple of days in between work and travelling. Got a back-up phone so it's not that bad. But I really like this phone! It's just been such a pain in the ass the past few days...
I tried researching online and reading all the XDA posts. It is my fault this has happened and feel such a newb for not being able to fix it myself
Many thanks in advance!

What I've tried:
- Flashing the stock B09 update.zip with TWRP.
- Flashing the stock B09 update.zip without updater-script 'assert' and 'get-prop' line. TWRP says 'update.zip is corrupt'. Doesn't install.
- The I put it on SD card and internal memory and tried updating it with stock recovery: 'sorry you cant sdcard upgrade'. That's all it says.
- ADB sideload stock recovery: 'cannot load update.zip'.
I tried different ADB versions, Windows and Mac, different drivers... I tried formatting SD card as FAT32.. Tried different SD card.. Doesn't make a difference.
TWRP log says it can't pass the Zip verification when I try that. If I turn that off it says re.product.name is wrong. But I checked build.prop and updater-script. It's the same! But somehow TWRP comes up with a different one. Also tried removing getprop and assert lines from updater-script. But then it says: ZIP file is corrupt.
TWRP log after trying original, stock B09 flash:
http://pastebin.com/cJivE2TK
Build.prop: moved from /system with TWRP:
http://pastebin.com/b6rryc2n
Build.prop: ro.product.name=P996A03
Updater-script:
Code:
getprop("ro.product.device") == "ailsa_ii" || abort("This package is for \"ailsa_ii\" devices; this is a \"" + getprop("ro.product.device") + "\".");
assert(getprop("ro.product.name") == "P996A03");
But TWRP log: ro.product.name=cm_ailsa_ii
So, yeah, I've been trying on and off for the past couple of days in between work and travelling. Got a back-up phone so it's not that bad. But I really like this phone! It's just been such a pain in the ass the past few days...
I tried researching online and reading all the XDA posts. It is my fault this has happened and feel such a newb for not being able to fix it myself
Many thanks in advance!

Dear All,
ZTE Axon 7 A2017 (Chinese version) Stuck on Bootloader mode.
Device after power on will Stuck on ZTE logo even power button press longer also will Off and came back to square one and the only way to power off is via selection on bootloader page via volume button which consists of Recovery mode, Power Off, Bootloader and some other mode which I can't recall.
History of this issue. Please bear with long story.
Manage to install MM ROM with B13 via sd card installation via update software in phone setting. follow by Unlocked bootloader and Install TWRP 3.1.1.0 then try few different ROM until one day when I use Xiaomi flashtool my PC crash half way through during flashing resulting in device with Pure Chinese ROM and TWRP also got corrupted, when I said corrupted because I install TWRP 3.1.1.0 but when I go to Recovery mode it shows TWRP 3.0 something. with this corrupted TWRP when I try to install ROM it will show loading but end result is NIL meaning same ROM nothing change.
Until this stage I never did a TWRP backup because all this while the ROM is Not my type of ROM from this junction when I boot back to TWRP and I did Advance Wipe most of it except external sd card thinking that I may be able to install fresh TWRP but my Recovery TWRP is residing in phone storage resulting in No more TWRP recovery software. next thing I did was I connect phone to PC and ran adb fastboot tool to detect device and managed to detect device in recovery mode and I make decision to Locked back the bootloader and did just that and Locked bootloader is Succes and it also Erased everything during the process.
To cut short the story after Locked back bootloader only Bootloader mode is accessible and when I connect to PC and enable Recovery mode (Black screen) and EDL mode (Black screen) from Windows PC Device Manager COM port able to see Qualcomm 9008 for this 2 mode.
I must admit after few days of trying to resolve this Stuck Bootloader issue I almost give up.
Then I remember this Woodo magic by jcadduno which recommends XM flashtool version 2016.08.30.0 but unable to flash after trying few version Xiaomi flashtool and the very latest and I mean from Xiaomi Flashtool webpage http://xiaomiflashtool.com/
version 20170425 that break the ice and finally able to load A2017U ROM because this US ROM my phone No Network detected.
From here onwards I unlocked bootloader and install back TWRP (Installation of TWRP via Axon7toolkit) because of Network issue since I got TWRP I install back A2017 ROM but still Not satisfied because Chinese ROM certain Apps having issue because of Google services and I chance upon this Conversion A2017 to A2017U ROM (Hybrid ROM caused ROM is US and Modem from Chinese Modem)
that I'm stay put right now and my phone now is A2017U model.
I hope this experience can help others with similar Stuck bootloader and those who wish to convert A2017 to A2017U ROM.

I am stuck in a position where I can restore my nandroid backups but get Error 7
when trying to reinstall any Rom on a2017u I was able to fix the unlocked bootloop
by the EDL method. The Rom's are the same as the backups. I think I tried to role back to B29 Causing the bootloop) and have had problems ever since.
Should I try flashing A2017Uv1.1.0B32_Bootstack_by_DrakenFX since the Rooms are all B32?
The B15 and B19 Nandroid's still Restore fine.
Hello all,
i don't get onto forums very often but i thought this was a nice one to add to. i've rooted a few motorolas, a few ztes, a cat; i've also bricked those ztes, cat & a few samsungs. i'm dealing with two Axon7U's; one is factory MM-b29, the other is N-b35.
while screwing around with TWRP, i bricked the b35 (the b29 has been bricked for a month at this time) after i had it almost perfected. by perfected i mean a custom recovery & root user access fully acquired. with DrakenFX's {YOURS; thanks so much. i'm learning to get along with linux} extensive files created to save people from themselves i was able to unbrick the b35. albeit its CELLULAR DATA became unhinged; that's something i could've lived with except it was a loaner and had NO CAMERA! it's camera (along with the ability to push both volume buttons at once for say EDL mode...) was damaged having been beaten across a steering wheel several times. so with my newfound unbricking superpowers i decided to take another crack at the b29. managed to get it unbricked but couldn't get it setup with both TWRP & SuperSU without losing one, the other or, both. at times it didn't even boot up. i was doing pretty much everything cited above for reasons 'why'. best way to learn is by trial & error (if one can afford it).
the b29 is rooted right at this moment; i'm working on it as soon as i leave this posting. i used Axon7_EDL_Tool. i used Axon7root. i used MiFlash. i used Fastboot. I used ADB App Controller software too. back & forth i fought for three days mostly due to downloading glitches and i prevailed. i manipulated a stock OTA full system update.zip by happenstance and it Auto_Updated over itself. in other words it already had the same ROM installed. i don't know what it tested to realize it needed to update to what it already had. it didn't have CELLULAR DATA either. just like the b35, it broke somehow while flashing TWRP or SuperSU. funny thing is it still wanted to update that same ROM after it did. while perusing the system update setting(s) i noticed it had downloaded N-b15 and it wanted to update b29 AGAIN! i opted for the Nougat update. it did alright and appears to have fixed it's CELLULAR DATA too. i haven't looked at it since but i'm confident i can gain root user access with a minimal amount of effort.
The main problem i've had with dealing with bricked devices is the age of the file downloads. most of them are simply GONE!, expired links and whatnot. if i'd had a clear path say from a custom recovery and rooted boot image of my factory version or the path that leads to it, i'd have been fixed up long ago. i've found partial 'paths' if you will that almost get me there but no quite all the way. flashing images & zips through fastboot are different from their counterparts entered through TWRP or Emergency Download Mode which of course are both different too. three different ways to get into one's phone makes it almost impossible to keep them perfected.
i'm not sure i did what i'm supposed to regarding this thread. Thank you DrakenFX for your time & knowledge; you've saved my old Axon7!
Hello all update;
b35 Nougat phone is retired. b29 managed to update itself to b35 7.1.1. however, its CELLULAR DATA is still broken. i haven't managed to figure out how or where it's broken so i cannot fix it.
what i'm trying to do now is flash Magisk instead of SuperSU and using a TWRP version 3.0.3-1. heck i've used all of TWRP's versions in my efforts to reacquire CELLULAR DATA.
crazy part is the phone knows its CELLULAR DATA carrier and freely displays all of its hookup info. this is very frustrating.

Recovery unaviable after Nougat update

Hey people,
I've updated to the unofficial Nougat leak here and ever since I can't get into the recovery. The ROM is OK but no matter what I do I can't get into the recovery. After "adb reboot recovery" I just get stuck in a boot loop and I must get into the upgrade utility and restart phone into the system from there. I've tried to flash few other recovery but nothing works. So far I'm fine with the system and I'd like to also try LineageOS but I have no way to flash the ROM. I have tried "Fastboot flash zip xx.zip" from the bootloader to flash LineageOS but it told me I don't have permissions so it was no good.
So do you folks here have any idea what I did wrong and how to make the recovery work again? I'm kind of learn from the tutorial guy so I'll post the sources I've been using to do the flash.
Unlocking bootloader and flashing new recovery
I've only used the unlock bootloader and flash twrp sections with their provided recovery. I've also tried to flash THIS recovery by Meticulus after the nougat update.
Flashing the ROM + used ROM
Used the old process because upgrade with system utility kept giving me errors.
Model number - VNS-L21
Also if this issue can't be (yet) fixed do you know any way to safely flash ROMs without recovery?
Thanks for any kind of help
You cannot flash any ROM in the nougat recovery, because it does not support /data mounting. Downgrade to MM and install the ROM you want from there.
@SALVO9
Ok, thank you for the reply. I'll probably try to downgrade and flash it afterwards to know which ROM suits me better. All I need to do is find the stock ROM copy it to the phone and restart with all buttons pushed right? Also, do you have any info about when there will be a nougat recovery that can mount /data?

No.
Flash proper OEMinfo first!
@Schlengge
Thanks for the advice. I did my research because I didn't know a thing about oeminfo and I have hit a wall since my phone is not rooted(Should have mentioned that earlier I know) and I'm supposed to replace custom.bin and then flash the img. So afterwards I searched how to root this nougat ROM and found nothing no app was working and everything I found was just using the phone's recovery which I can't access. Does anything come to mind? I will continue getting through the pages of google but I don't think I'll find anything useful.
EDIT> After some searching I found the official rollback package. I have yet to test it (downloading on slow connection atm) and I hope it will work.
Ok it's finally done and I'm back at old stock ROM(EMUI 4.1.1 VNS-L21C432B160) after hours of searching I gave up on the oeminfo or rooting the phone. I searched for the stock firmware and found some rollback packages on the Huawei site. I will post the links in there you even have instructions packed with the zip.
LINK1
LINK2
Download both start with the smaller one because it's flashing first and follow the instructions in the pdf. Worked for me so hope it also helps you.
Also as I found out just now this rollback also locks back your bootloader so be sure to unlock it back again with the code.

Need backup img for tb-x304f

Hi I have tb-x304f.
I installed TWRP to get root access and by mistake I deleted my backup and now I can't update to 8.1.
So can someone give me backup img?
Thanks :good:

They don't have images like Google devices, but flashable firmwares.
http://lenovo-forums.ru/files/category/287-lenovo-tab4-a10-tb4-x304l/ has it, second from the bottom, underneath all the OTAs. Double check that you got the 4F and not the 4L one.
I don't have this device so I cannot help you with it if you have issues, nor can I say this will work for you. I also really don't profess to be any kind of an expert so do ask in one of the other Tab 4 threads if needed... but I do have the TB-8704F & have restored it to stock several times and I would assume the devices to be identical in process so I can give you a guide if needed! The general path is:
Download the zip and extract it
Download and install Xiaomi Mi Flash (some say to use QFIL but it often throws up errors and sometimes requires flashing in multiple passes, when Mi Flash doesn't)
Plug your device into your PC
Put your device into Emergency Download Mode, easiest way for you is probably to first reboot to TWRP which you luckily already have installed
In TWRP go to Advanced>Terminal>type Reboot EDL
Open Mi Flash and it should see your device. Click Select, open the images directory in your extracted firmware and it should detect the flashing process XML
Click Flash, then leave everything to complete
I will warn you that you will lose everything on your device. There's no way around this that I know of, nor would I suggest it anyway. Just back up everything before doing the restore.
+ Good luck! But honestly I'd first weigh up whether you really want to update to 8.1 since you're already on a perfectly-working device. They already pushed the OTA once and had to retract it because of the amount of serious errors it had - but that's your call entirely.

bro help me unlocked the bootloader yesterday and flashed recovery but then decided to downgrade the system with system sparse image in fastboot mode provided by o.p. of rooting thread, but now it is not booting up just showing lenovo logo and in fastboot mode again

(SOLVED) I used TWRP and accidentally wrote over the boot recovery partition

Hello,
In a late-night act of utter stupidity, when over-tired, I re-flashed the boot recovery with TWRP and bricked my M3. It obviously can't now enter boot recovery.
I've used TWRP and successfully re-flashed custom roms on my original Mate, and changed regions. (Not in any way an expert, I know how to follow instructions.)
I was trying to convert my Chinese (I was living there) ROM to UK. It's tricky nowadays.
This was a stupid error when tired. Any way back?
I read somewhere that people with the right hardware can do it, but finding someone. I'm in Leeds, UK.
The pad does (did) what I need, and I'm not in a position to buy a new one. If it's dead, it's dead; and I can move on.
Cheers in advance for any input.
SOLVED
See my last post on this thread.
After using Multi Tool V8 to enquire into the machine I switched off and rebooted.
It came back with a "Wipe cache" and "Reset to factory settings" Huawei screen, so I did both and - It booted!
It had spectacularly failed to do anything but boot-loop since coming out of a very dead battery yesterday.
1) Boot recovery, OTA recovery, and dload recovery from SD were all unavailable after the original overwriting of the bootloader.
2) After being dead for months, all recovery options booted from power button plus vol- Vol+ and Vol+/- - but still bootlooping.
Then, suddenly it booted into wipe cache/factory reset screen.
Android 7, EMUI 5.1.3
I have no idea why.
Now fully working. (Including restarting)
I fell in a similar situation after having flashed a magisk module .. unfortunately my nandroid backup didn't restore my devices, but I was able to enter in twrp recovery.. so,..
if you can boot in twrp recovery, not all hopes are lost..
first of all, you must download a stock firmware for your device (i suggest to download trough huawei firmware finder: https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146/amp/)
You must download a fullota version of stock firmware
then, you can flash this firmware (3 zip files) trough hurupdater via twrp recovery: https://forum.xda-developers.com/ho...lash-official-firmware-recovery-t3769279/amp/
in order to not overwrite twrp recovery, put the twrp.img file in the same folder and rename it to recovery.img
you can find more info in this topic (follow the instructions, in particular those on how to use hurupdater): https://forum.xda-developers.com/me...ting-btv-dl09-to-unapproved-firmware-t3817541
in order to find a firmware suitable to your device, try to find info on it: you have a mediapad m3 European? American? asian? just wifi or also 4G-LTE (whit a sim and phone functions)? lite or normal version? 10 inches or 8.4?
everyone of these devices have different codenames and suitable firmwares
I found exact firmware for my devices with the procedure described here:
https://forum.xda-developers.com/showpost.php?p=77241673&postcount=3
.. but, if you flashed a wrong firmware, i really don't know if it might help you..
anyway, i wish the info above could help you.

Thanks for the reply, and sorry for the delay. New child has somewhat taken over our lives!
I'll take a look at the tablet again when I have time, probably next month.
Update - Bootloader working after battery drain: Now what?

Well...
After being without power for so long I turned the tablet on and it booted!
However, it then went into OTA and updated - rebooted - and locked the damned bootloader.
1) It's showing as rooted.
2) Boot loader is locked.
3) Fastboot & rescue mode comes up.
4) Recovery (OTA) still comes up but "Fails" this time.
I don't recall how I unlocked it last time. I don't ever rememebr an unlock code.
Status:
Fastboot reports it exists.
ADB reports "Null" not found. (ADB drivers installed).
Firmware version: CPN-AL00C233B078
Device name: CPN-AL00
Serial Number: Showing
IMEI: Showing
Bootloader state: LOCK
I have an old TWRP backup - don't know how to use it.
Solutions?
a) Any kind devs prepared to work with me and find the boot unlocker code for this 5-year old tablet?
b) Any other solutions now we know what's what?
I'm self employed without income in this pandemic and can't really afford to buy a new tablet. If I have to, it won't be Huawei.
(There's a T3 10.6" at £89, but I'm not biting - I need to sort out a budget tablet with at least the oomph of the M3.)
Any help much appreciated. :good:
David.
