This tool is to downgrade from Oreo public release build?

Bcz i downgraded from oreo beta by the old version just normally today
[Nokia 6 Guides, News, & Discussion] Gonz19:
Yes, you can use the old tool with Oreo beta because Oreo beta doesn't upgrade your bootloader. The official one upgrades everything

quertysmerty and Heineken 78:- hicari calyx is right. After editing online update config from 98 to 99, though it opens but only the last option (check system ap info) is there, hence one can't flash any firmware. Please could you help us fix the issue. Thanks

Hilarious calyx By the way I only want to downgrade to nougat cause I couldn't root oreo. I'd appreciate if you can aid us with a tutorial on how to root official oreo release. Thanks

Well, I managed to flash the recovery I used for Nougat build, it still boots, but userdata partition can't be mounted. It means the TWRP needs to be updated to adapt newer aboot.
[Nokia 6 Guides, News, & Discussion] Bawuro:
How did you manage that? Because I followed your guide on how to root nougat. Didn't work out for me. Could you explain how I can flash TWRP. That's all I need. I have a nandroid backup I need to restore. Please I eagerly await your response.

---------- Post added at 12:45 AM ---------- Previous post was at 12:37 AM ----------

Can you instruct me on how you managed to flash the TWRP, cause I followed your guide both on XDA and YouTube. Didn't work out for me.

This requires an account to OST LA 6.1.2, which I can't share.

Method is almost the same.

If someone could patch the latest version OST LA, this will be possible.

Heineken78 has patched it now.....
[Nokia 6 Guides, News, & Discussion] heineken78:
New nb0 unpacker/repacker is done, but is't time to publish it yet.
[Nokia 6 Guides, News, & Discussion] Bawuro:
Okay. But how about the flashing of TWRP so one can restore a nandroid backup?
[Nokia 6 Guides, News, & Discussion] heineken78:
all can be done in nb0 formal (or mlf) :)
[Nokia 6 Guides, News, & Discussion] Bawuro:
Can you explain that please. You see I have this backup I desperately want to restore. But this Oreo update won't allow me to flash TWRP custom recovery.

The nbo you refer to where can one find it please?
[Nokia 6 Guides, News, & Discussion] heineken78:
hahaha if you read logs from first page..

Oreo has new oem command oem dm-veracity

so get serial number of your nokia (letters and nubers), get md5 from this string.(ex. 0d0799797899798080...)

use it on fastboot oem dm-veracity 0d0799797899798080

then fastboot flash recovery yourfile.img
[Nokia 6 Guides, News, & Discussion] Bawuro:
What? I'm a noob :D.
[Nokia 6 Guides, News, & Discussion] heineken78:
And I dont have any Nokia's :)
[Nokia 6 Guides, News, & Discussion] Bawuro:
Okay :(Thanks anyway.
[Nokia 6 Guides, News, & Discussion] :
dm-veracity will give you nonce challenge, which should be encrypted with RSA-2048 key on server and send back to phone.

md5sum(productid) is removed because HMD noticed patched OSTLA and did not like this ;)
[Nokia 6 Guides, News, & Discussion] heineken78:
This is case with older chipsets that have oem commands in aboot. Return to older aboot gives you old algorythm.

But I noticed newer chisets 630+ and 830+ have oem commands in fuses not in rimware. How do they will manage it?

PLUS, why you are so sure about new encryption? May be they just changed the word and expected new LA not working offline?

..or you are the guy who were unlocking bootloaders with old md5 algorythm fired this changes up :)
[Nokia 6 Guides, News, & Discussion] wachiwachi:
Hello. It is possible to convert to nb0 a 1003 ROM wich is a ZIP?? And then flash it to a TA-1000??
[Nokia 6 Guides, News, & Discussion] :
if EDL cable still working - no problems to downgrade bootloader ( under question if new android will boot with old bootloader ).

i'm lost somehow my EDL cable, will build now new one and test if phone can enter EDL.

but it EDL cable was SOFTWARE thing, then to flash aboot you neen to pass new RSA authentication or disassemble phone to use hardware factory testpoint.

in fact, that RSA authentication were already present for different things ( for example, to boot FTM image ) , but for unknown reason they not used it for critical partitions flashing authentication.

why you think so ?

i'm 100% sure about this, because i'm have IDA and know, how to use it.

beside this, i'm have plenty of useful documents ;)
[Nokia 6 Guides, News, & Discussion] heineken78:
;)

Cracked OST knows how to put in emerency mode if you select it (i hope)

I have Ida too (no wonder)

About aboot, use search for commands and you find them in aboot image. New chipsets, i have analysed, besides not having sbl and aboot have xbl and abl and firmware has no commands inside ;)

So check cracked version of OST, may be its still can download hash, cos i replaced login function with super user function from login function inside. )))
[Nokia 6 Guides, News, & Discussion] :
it is NOT working with new bootloaders ( dm-veracity )

also, i'm assembled cable and it does not enter EDL on new bootloader. it is still possible that i'm soldered wires bad, but i'm checked with cable tester ... all is fine.

congrats, but i'm have legit one ;)

starting from msm8994 qualcomm changed signature format and changed sbl1/2/3 chain to UEFI xbl/abl chain.

google for "UEFI capsule" ( hint LZMA )

it does not work - service center commands now have auth is on server side.

good news - unlock bootloader implemented now, so i'm expecting HMD to launch some hmd.unlockbootloader.com
[Nokia 6 Guides, News, & Discussion] heineken78:
I seen it in flash dll, can easily be bypassed :)
[Nokia 6 Guides, News, & Discussion] :
you can bypass anything in OST on PC side, yet you can't bypass anything in phone ;)
[Nokia 6 Guides, News, & Discussion] heineken78:
reversing aboot.. FIH my ass:)

By the way aboot replacein pair with sbl
[Nokia 6 Guides, News, & Discussion] hikari_calyx:
Thanks a lot!
[Nokia 6 Guides, News, & Discussion] minhas729:
So the tool is fully functional to downgrade from Oreo to nougat now?

If yes please update the Post 1 with installation details of patch as well, please ?
[Nokia 6 Guides, News, & Discussion] hikari_calyx:
Yes, I'll update the detail ASAP.
[Nokia 6 Guides, News, & Discussion] :
you CAN NOT downgrade oreo ( bootloaders with security level >= 0004 ) with this PATCHED tool

you can only do it, if you have account on sts.c2dms.com
[Nokia 6 Guides, News, & Discussion] Bawuro:
the_laser you know I've been reading your posts, first in response to Heineken78's response to my post and now to the entire thread. If you know what the rest of us don't, why don't you help us out? I mean you seem to know how to unlock bootloaders. what do you say?
[Nokia 6 Guides, News, & Discussion] heineken78:
But you can unlock bootloader before Oreo update.

Unlock is stored where? You might know!

So why just don't replace this partition and have unlocked phone without unlocking procedure?

You people have sahara 9008 preloaders available for all nokia 2-8 and still have problem with locked bootloader? OMG!

---------- Post added at 06:53 PM ---------- Previous post was at 06:33 PM ----------

He mean soon will be online service from nokia for unlocking
[Nokia 6 Guides, News, & Discussion] :
of course, with proper preparation we can get oreo with unlocked bootloader - first, most obvious way :

- unpack .nb0

- change D1C-0-522A-emmc_appsboot.mbn to D1C-0-3700-emmc_appsboot.mbn

- correct md5.dat

- correct ND1-522A-0-00WW-B03.mlf ( dm-veracity to dm-verity )

- flash with OST or with fastboot ;)

BUT you see, this thread here how to downgrade phone/unlock bootloader AFTER it was flashed ( via OTA, for example )

and the thing you CAN NOT enter EDL mode on new bootloader without disassemble phone or via online authentication.

it is already up and running.

soon will be released for all.
[Nokia 6 Guides, News, & Discussion] Bawuro:
Now that's good news.
[Nokia 6 Guides, News, & Discussion] heineken78:
you will get the brick :)

always change aboot together with sbl in pair.

and in nokia 7-8 they are not able to change dm-verity command, thats flashed in fuses?
[Nokia 6 Guides, News, & Discussion] :
you don't have any nokia, how can you be so sure ?

dm-verity is done exactly for unlocking flashing of critical partitions, as they called it .
[Nokia 6 Guides, News, & Discussion] qwertysmerty:
I think at the moment you can do this by flashing OTA zip from SD card. Noticed in December's updater-script that it overwrites sbl/aboot before writing system. So if you try to apply Nougat December update on top of Oreo it will fail, but before failure it overwrites sbl, aboot, and recovery. So old OST LA should work again.
[Nokia 6 Guides, News, & Discussion] heineken78:
This is QC. For example downgrading aboot from Lollipop to KitKat was causing brick, even usb cable was helpless, only cutting pins on emmc helped. So aboot and sbl are compiled in pair, replace them both for bigger chance of working.

Does nokia has feature to install from recovery? So far I know latest Sharp S2 made by FIH, is updating OTA zips from Android. Recovery is completely useless, only makes data wipes.
[Nokia 6 Guides, News, & Discussion] qwertysmerty:
Yes, you can install ota zip from recovery in Nokia.

---------- Post added at 10:18 AM ---------- Previous post was at 10:14 AM ----------

Hope they wont tight bolts further and wont remove that ability from recovery.
[Nokia 6 Guides, News, & Discussion] heineken78:
in Sharp case update is done via payload.bin, when stock recovery starts with zip, its writes error: can't find/mount /cache :) so its even not adopted. But Sharp using everything same as Nokia- nb0 format and OST utility (may be another version?) files sutinfo containing same files..

Only problem there is no factory nb0 rom leaked, very need 9008 programmer from it..programmer from Nokia 7 has different signature.
[Nokia 6 Guides, News, & Discussion] SimGa:
I'm using OST LA 6.1.2 to unbrick my Nokia 5 after a failed Oreo OTA-zip update in the recovery menu.

OST LA 6.04 gave me the error: SE_ERR_ADB_CMD_GET_FAIL_RESULT.

Now, OST LA 6.1.2 is at second 800 still flashing service bootloader. Do you think its save to close it and redo the procedure again with emergency download? Any other suggestions why OST la 6.0.4 failed?

EDIT: I closed OST after waiting 1200 seconds and tried flashing with emergency download. OST stops after trying to poll my phone with the error DEVICE_NOT_CONFIGURE (0x4000)
[Nokia 6 Guides, News, & Discussion] heineken78:
Pls attach logs from c:\LogData

The main fault was that device aboot was updated to new security during flashing.
[Nokia 6 Guides, News, & Discussion] heineken78:
You need to unpack nb0 file, then take 3 files from it: programmer file (prog_firehose..blabla.mbn), emmc_appsboot.mbn and sbl1.mbn

then flash it manually via emmcdl tool in emergency mode, then you will be able to use OST 6.0.4 again. Tool https://xdaforums.com/showpost.php?p=69759574&postcount=109

flashing like:

emmcdl -p COM3 -f prog_firehose..blabla.mbn-b aboot emmc_appsboot.mbn

emmcdl -p COM3 -f prog_firehose..blabla.mbn-b sbl1 sbl1.mbn

where com is port number of Qualcomm 9008 driver

Perfect case will be making qpst recovery for nokia 5 from all unpacked files, but I can't download nokia 5 firmware, cos Russian site is blocked by idiots Ukrainian government.
[Nokia 6 Guides, News, & Discussion] SimGa:
Thank you for your guideance. I can't download emmcdl from your google drive as it says its a violation of their Terms of Service.

But i guess I can just download it from somewhere else.

Whats the trick to get into 9008 mode on nokia phones? I've tried several key and plug-in-just-in-time combinations, but none worked. I've already uninstalled and reinstalled the qualcomm usb drivers several times.
[Nokia 6 Guides, News, & Discussion] heineken78:
read forum, nokia require special download cable or short cutting of specific wires, to get in 9008 mode.

Without 9008 mode u are not able to do anything now with updated security.

If you are able to enter fastboot, why you cant enter recovery and reapply update.zip?
[Nokia 6 Guides, News, & Discussion] SimGa:
I've tried with short cutting black and green wire as I could find it in the forum. But if I connect my phone while having the two wires connected the phone just goes to the "Powered by android" screen and does nothing else. And the device manager of windows doesn't recognise it at all

I am able to enter recovery(despite having a "no command" screen before), but every time I reapply update.zip it loads the file, verifies it and while verifying the phone restarts and gets stuck at the "no command" screen again.

EDIT: Somehow it suddenly worked to get into 9008 and I could flash the files using your guide with emmcdl. OST6.1.2 doesn't work, but OST 6.0.4 does now. Now it flashes the bootloader successfully, but gets stuck due to a low battery power warning. Unfortunately, it doesn't seem like my phone is charging(it only shows the Powered by android screen)

EDIT2: Finally, I got it working again. Thank you so much, you saved my from being weeks without a phone :D
[Nokia 6 Guides, News, & Discussion] heineken78:
Ist looks like downgrading to old aboot and sbl1 bootloader files, makes "old" security working again.
[Nokia 6 Guides, News, & Discussion] :
thats the point of downgrade.

main question is how to reliable enter EDL mode on latest bootloader.

my phone received ND1-5220-0-00WW-B01 bootloader and i can't force phone to enter EDL with EDL cable - phone just power on, like in SimGa case
[Nokia 6 Guides, News, & Discussion] heineken78:
test points left. or upplying update.zip at bootloader fase reboot phone, that will cause corruption and EDL mode.. but you must be very lucky.

Basically corruption of any of system partitions may lead to EDL mode.
[Nokia 6 Guides, News, & Discussion] :
testpoint require phone opening, which can ruin it ;)

yes, need to corrupt any sbl files, probably best way to terminate update procedure in very beginning ...

but SimGa somehow entered EDL - probably he will shed more light on this.
[Nokia 6 Guides, News, & Discussion] Mayersdz:
I'm ofc Oreo user can I use this to roll nougat now ? ?
[Nokia 6 Guides, News, & Discussion] heineken78:
Everyone is waiting how you did that )

I've read on Russian forum about one of nokia models, they manage to run EDL with combination of download cable and pressing vol+ and -. It works till you keep pressing buttons. But this post was before Oreo update.
[Nokia 6 Guides, News, & Discussion] SimGa:
I just tried it again using my DIY cable and it worked on the first attempt without any need to press a button.

1. Make sure you have the qualcomm usb drivers installed(i also have installed QPST, but i didn't use that)

2. Turn off phone COMPLETELY and wait a few seconds

3. connect Micro USB to phone, Computer side not connected.

4. Connect green and black wire and keep them connected(make sure to have a good connection. I attached a 2.54mm jumper plug and socket)

5. Plug in USB cable into computer

6. If the screen on your phone stays black, disconnect green and black wire after a few(5-10) seconds. (If it shows "powered by android", going into 9008 failed)

7. Voila, you're in 9008 mode.

It's important to be able to disconnect the green and black connection as the port shows up after disconnecting them. The tinfoil-strip trick in the usb connector doesn't work here.
[Nokia 6 Guides, News, & Discussion] qwertysmerty:
But what version your phone runs right now, Oreo or Nougat?
[Nokia 6 Guides, News, & Discussion] SimGa:
Remember: I am using a Nokia 5 (TA-1053) and I am now back from Oreo Beta to Nougat.

I was on Oreo Beta( don't know which version exactly, but I guess it was 5.190) when I tried to update to Oreo Stable with a OTA-zipfile I found in the forum(using the recovery menu). I hadn't checked which version it was exactly (silly, I know)

Anyways, I got a "No command" screen, but I could still access the recovery menu which showed me 5.220(just as the_laser), which is weird, because the stable Oreo version for Nokia 5 is v5.200.

OST LA 6.0.4 and ADB sideload both failed when I tried to upload any OTA zip file(regardless if it was an update or a full verison)

I didn't really care which version I'll get at as long as my phone runs again. So I downloaded an extracted version from the "Unbrick your Nokia 5 Guide) which has the firehose files and so on.

I then patched the firehose files to get a Nougat bootloader and uploaded the 3700 nb0 file.
[Nokia 6 Guides, News, & Discussion] qwertysmerty:
So you're entering 9008 mode right now having Nougat, not Oreo.

I think you managed to enter 9008 previously after one of attempts to install update.zip from recovery overwrote aboot and sbl from Nougat
[Nokia 6 Guides, News, & Discussion] SimGa:
Oh, yes you are right. I can only test 9008 mode for Nougat right now. Sorry, I haven't received the oreo Ota yet. As soon as I have it, I'll report if theres any other trick i findto open it on oreo

sharp aquos s2 brick (EDL 9008 - halt)

Question to enthusiasts.

Have Sharp Aquos S2. Was trying to make it run in EDL mode (9008) without cable tricks:

flashed service "abl" bootloader, then flashed anything to "xbl" , after reboot I got EDL mode 9008 but..

Phone is hanging in 9008 and doesnt respond to programmer or querying, no any buttons are working.

Any solution? Searching of test points will bring to normal EDL mode, or need to short cut contacts on emmc directly?

so either remove cable, flash boot or just send reset command to EDL loader using fh_loader ...
