I have a Mediapad M5 Pro CMR-AL19 (432) with firmware 8.0.0.195 and security patch of first of January 2019.

I tried to downgrade it to version 8.0.0.161 as described in post #209, the downgrade was successful and now in the system information the installed firmware is 8.0.0.161 but the security patch is still that of first of January 2019 and obviously I can not unlock the bootloader.

I also tried the downgrade to versions 8.0.0.122 and 8.0.0.151 but without success, the flash process fails at 5%.

How can I downgrade the security patch too?
[Huawei MediaPad M5  Guides, News, & Discussion] JiiJii:
Sase situation here with me cmr-al09. I downgraded to 8.0.0.161 but the security patch is january 2019. DC-unlocker can't read bootloader code, unknown error 375 appears.

Any ideas what to do?

Issue with 8.0.0.190

Im having an issue with the DC unlocker and mediapad m5 SHT-W09 8.0.0.190(C567) build. DC unlocker says

'Reading bootloader code...

unknown error (375)'

when I try to get the code. Does anyone know a work around yet?

Edit: My security patch is October 1, 2018 not the January like most people who also have this problem are running
[Huawei MediaPad M5  Guides, News, & Discussion] supervhizor:
So can I downgrade to 8.0.0.167, unlock the bootloader, upgrade back to 8.0.0.190 and root or will the bootloader relock itself during the update? If it does is the unlock code still the same and I can just re-enter it after the update or do i need to STAY on 8.0.0.167 indefinitely?

Edit: after re-reading your post, I realized I'm an idiot. There should be no problems, right?
[Huawei MediaPad M5  Guides, News, & Discussion] :
Same probleme here from 8.0.0.195 . can't downgrade, it fails !
[Huawei MediaPad M5  Guides, News, & Discussion] Fredheg:
The security patch must under july 2018 to works with DC unlocker. DC unlocker use a fail break to read the bootloader code.

The fail Was corrected After july 2018

Are we lost now with the .195 firmware and security patch from 2019?

Cant believe that.

An developer of huawei can open the bootloader, too.

should we contact the dc-unlocker team?

I managed to downgrade from 8.0.0.196 with security patch February 2019 to 163 with security patch November 2018. But the security patch won't downgrade. Anyone know how to force the security patch to downgrade?

I was wondering if there was a way to completely wipe the OS from the tablet and then reinstall it so there wouldn't be previous version to mess the security patch.
[Huawei MediaPad M5  Guides, News, & Discussion] bombername:
That´s also the point where i am right now.

The issue is still the security patch level January 2019.

So you can´t unlock the bootloader again.

I have the bootloader unlocked and I am still on 8.0.0.181(C432). Can I flash the latest OTAs or will my booloader get re-lock and I will lose root access?
[Huawei MediaPad M5  Guides, News, & Discussion] Tool Belt:
You will not re-lock. You will lose root but that is easily retained following this thread (FOR YOUR MODEL).

Hi! I just bought M5 10.8 from amazon, and first thing I always do with new device is unlocking bootloader and rooting.

I'm a bit confused. Can I use this way of unlocking bootloader in CMR-W09 8.0.0.192 (c432) firmware with November 2018 secturity?

If there is NO way to unlock my device's bootloader and root I'll simply return it. All my android devices I ever used were rooted.
[Huawei MediaPad M5  Guides, News, & Discussion] StephenMSmith:
Nope. You need to get all the way back to the firmware from last June and then purchase code from DC-unlocker. Unfortunately, I haven't seen anyone successfully doengradeboth firmware and security patches, so DC unlocker fails.

I got super lucky in timing, as did rest of us with unlocked bootloaders. If your set on this tablet try to go d used one already unlocked. Huawei can't relock an uocked booouafer, thankfully.

WiFi performance is shockingly bad due to lame antenna hardware and I think lack of mimo. But there aren't many tablet alternatives in this price range.
[Huawei MediaPad M5  Guides, News, & Discussion] flamand:
Is it at all possible to downgrade to a version that can be unlocked? (DC-Unlocker says no go to my SHT-W09 on 196.)
[Huawei MediaPad M5  Guides, News, & Discussion] goodwin_c:
As of now - only one possible way to downgrade is through testpoints (openning device) - you may find my guide. This is if you are impatient + you really need unlock. Otherwise i may suggest to not upgrade anymore and wait - maybe, one day, somebody will find another solution.
[Huawei MediaPad M5  Guides, News, & Discussion] mudnightoil:
Can someone state what the last known good firmware (to unlock BL) was for the M5 8.4 LTE? SHT-AL09

Most Huaweis bought from China come with ancient firmware, so I'm guessing it's possible that if buying a new one now, BL unlock is possible.

Want to know the last known good BL unlock friendly firmware so I can then ask the sellers what it has factory.

Thanks.
[Huawei MediaPad M5  Guides, News, & Discussion] id4rox:
I have the US wifi version, but it seems like there are still issues with downgrading beyond a particular android security patch. I've been trying to figure out if it's possible to replace the version on the recovery partition with an older version that's unlockable, allowing for a simple factory reset to get us to a version we can work with. I haven't figured out yet how to do it, and my downgrade attempts in general haven't been working :(
[Huawei MediaPad M5  Guides, News, & Discussion] mudnightoil:
A lot of Chinese Huaweis ship with ancient FW though (and won't have later patches).

[Huawei MediaPad M5  Guides, News, & Discussion] ferraript:
Unfortunately not all of them then. I bought mine at GearBest, it arrived yestareday. Firmware is 8.0.0.190 (C636). DC-Unlocker can't identify it and downgrade attempts failed :(

---------- Post added at 11:02 ---------- Previous post was at 10:56 ----------

Buying should be moved after the point 9. Because if the tablet has new firmware, DC-Unlocker won't work and users spent those money for nothing (and they have to apply for refund if possible).

So check if DC-Unlocker can recognize the tablet first and then pay.
[Huawei MediaPad M5  Guides, News, & Discussion] ferraript:
None of the unlocking service is working anymore at the moment. I'm afraid we are stucked for good :crying:

This is not possible for anyone with the 8.4" version since there's no testpoint info for the board. I found this out after opening it up, I even tried testing all the points on the board that gave less than 3v, front and back.

There is no hope, weep for root ye locked out plebs.
[Huawei MediaPad M5  Guides, News, & Discussion] goodwin_c:
It's not possible to not have testpoint. You just didn't find it yet :) It should be on board for 100%
[Huawei MediaPad M5  Guides, News, & Discussion] wag3slav3:
You're right, I finally found it. It's on the back of the board. I was able to use it to downgrade, still fighting with the software to get it into a state where I can use dc-unlocker client.

[Huawei MediaPad M5  Guides, News, & Discussion] wag3slav3:
I was able to downgrade to Android 6 since that's all that comes with the board software (Schubert-W09A-BD 1.0.0.18_Board Software_general_8.0.0_r1_EMUI8.0_05022GAE) using the testpoint then used Read booloader code from dc-unlocker I wasn't able to unlock the phone directly with dc-unlocker.

After that I went into upgrade mode (both vol buttons and power) and used dc-phoenix to load Schubert-W09A 8.0.0.190(C567)_Firmware_8.0.0_r1_EMUI8.0_05014YFX and Schubert-W09A 8.0.0.190(C567)_Firmware_8.0.0_r1_EMUI8.0_05014YFX - SHT-W09_hw_usa as an addon package.

Once I was back up to 8.0.0.190 I got into fastboot and ran fastboot oem unlock (code from read bootloader code) and I now have an unlocked M5 8.4.

I just received one 10.8 CMR-W09 with .192 and 5 Nov 2018 security patch.

In developer options there is the selection to allow OEM unlock.

Is there a method to unlock this device (e.g. fastboot oem unlock) , or I should let it update and hope for a future solution?
[Huawei MediaPad M5  Guides, News, & Discussion] Volumetrik:
Just got EMUI 9/PIE update for CMR-AL19.

I am also interested by the answer....

What the purpose of this setting ?
[Huawei MediaPad M5  Guides, News, & Discussion] wag3slav3:
OEM Unlock Allowed is a user setting that blocks fastboot from doing an OEM unlock when you don't want it. It was in your previous version's developer options too, you just didn't notice it.

You need that AND the OEM code from Huawei to unlock the bootloader. You can't get the code from them anymore because, reasons.

This is why we have to force a downgrade with testpoint to something that's exploitable and extract that code.

Hello guys, I was stupid enough to upgrade my M5 10" (wifi only model) to v. 9.0.1.182 without having an unlocked bootloader, because I thought I'd stick to the stock firmware.

Nevertheless, I've now decided I'd rather root. I did some research and it looks like it's virtually impossible to unlock the bootloader unless I manage to downgrade to some version before July 2018, but some people saying this is impossible without interefering with the hardware as well.

Do you think it would be possible to downgrade in a painless way so that I can use DCUnlocker, or am I doomed to a life of bloatware with my tablet? -_-

Thanks in advance.
[Huawei MediaPad M5  Guides, News, & Discussion] dahawthorne:
This is exactly why I abandoned any idea of buying a Huawei product even before the US embargo fiasco. Huawei's decision to actively prevent owners doing what they want with their own property (i.e. rooting) is a deal-breaker. It was bad enough even before that, having to jump through hoops to get codes from Huawei, but now they've broken even third-party unlockers. Quite why anyone in XDA would buy a Huawei product in these circumstances is beyond my comprehension. "Ordinary" consumers with no interest in software, maybe, but XDA members...?

Rant mode off... :)
[Huawei MediaPad M5  Guides, News, & Discussion] gravitycode:
based on your reply I assume I am doomed then. Why I bought it tbh is that it's actually the first time I invest in a tablet, I wanted an alternative mobile coding workstation and I'm pretty happy with the setup I already achieved (TermuxArch + LXDE running on a VNC client), the hardware is just fine for some light coding on the go, but the bloatware is getting on my nerves now.

I didn't do proper research, unfortunately, into all of this before I bought the thing. Up until now I always had android phones but never bothered to root because I spend most of my time at a laptop, now that this tablet turned into a laptop alternative however, I saw the benefits of rooting.

I guess I'll just have to live with it and know better for the future :good:
[Huawei MediaPad M5  Guides, News, & Discussion] dahawthorne:
I'm in pretty much the same situation with my Lenovo TB-8704F 8" tablet. It's a beautiful little device with a full HD display, and was upgraded by Lenovo's OTA to Oreo 8.1 a full year after Oreo was introduced. I expect no further upgrades from Lenovo, and the tablet isn't popular enough to have enthused developers to create any custom ROMs, so like you I'm just living with the results of a poor decision. The best I can say is that at least I was able to unlock it via Lenovo's website and then root it.

From a consumer perspective the tablet is a pleasure to use, but from an enthusiastic propellorhead's point of view it's a write-off. No more Lenovo for me.

That's your problem, DCUnlocker only works with an earlier version of EMUI - Huawei patched whatever they were using to read the unlcok codes from the device. I had to downgrade to 8.0.0.163 (possibly 8.0.0.160? it's been a while) using the method in this link before I could pull the bootloader code.

I booted it up and may have gotten lucky with the firmware.

Android Security Patch 1 September 2018

I successfully used dload method to downgrade to SHT-W09A 8.0.0.163(C432) see link ministryofsolutions.com/2019/03/huawei-mediapad-m5-sht-w09-downgrade.html

[Huawei MediaPad M5  Guides, News, & Discussion] pasha_d:
Newegg is shipping 8.0.0.173. It can be downgraded. If you enabled Wi-Fi and ran OTA and upgraded to 8.0.0.198 before obtaining an unlock key, then there is no way back. What I was saying that most likely all Newegg stock has 8.0.0.173 just in case someone is in the same boat as I was and looking for new 8.4 tablet.

There's hardly any development available for this device since Huawei u-turned their stance on bootloader unlocking, I had bought it already updated so there was no way, I've seen some guides but it means taking the whole thing apart and using jtag points to unlock bootloader and what not, I'm not really willing to go that far.

Tbh there's lots of options out there for decent Bluetooth Earphones and good price too, I have an adaptor/Dock with earphone jack and I don't even use wired earphones with it
