Hi all, I just bought the Lenovo Tab M10 FHD Plus (TB-X606F) and read about the widevine L3 problem. It's been a problem since day 1 the tablet was released. It seems like there was firmware updates last year that solved the problem, changing widevine from L1 to L3 and finally users can watch HD quality on Netflix and other streaming platforms? Can any current users or Lenovo confirm that it is true and it is possible to watch HD with this device on netflix/prime/hbo/disney now? If not I'll need to return it, I haven't open and use the tablet yet.
[Thinkpad Tablet General] fire_cuber:
Why don't you ask the support directly from the manufacturer???
[Thinkpad Tablet General] ibyz:
Well I did. No harm asking on different platforms right? Since I am also searching for alternative solution to the isssue.

You have to ensure that the internal battery is seated properly.

Better yet, simply replace the battery.

OK, here is something.

Bootloader mode:

Disconnect from USB or shut down Active sync processes

While holding Record button(near reset) and Quick Launch(top) press Reset.

It will reboot and the following will appear STEPLDR:1.00.01 BOOT:1.00.04 MVB.

Next press Rotate button, otherwise it will exit bootloader.

USB disconnect message will appear.

Now shut down Activesync processes if haven't done already and connect USB, USB disconnect message will change to USB.

Next, run mtty11a.

Select USB port, \\.\WCEUSBSH002 in my case

Terminal window opens, but unfortunately no messages or any prompt :(

[Samsung Galaxy Z Fold 4] Adv.Chirag:
So I am using AT&T version Zfold 4 model SM-F936U/DS in India and my software version is as follows:

Build number

SP2A.220305.013.F936USQU1AVGA

Service provider software version

SAOMC_SM-F936U_OYN_GCF_12_0003

GCF/GCF.GCF/XAA

Its stuck on android 12 May update.

I want to flash Indian firmware to make it Indian version of Z fold 4 for faster updates and enabling the call recorder.

What do I need to do? Any help will be appreciated. If this is answered anywhere please provide links to that thread and I will delete this one.

I am totally confused about CSC, firmware version, carrier version etc.
[Samsung Galaxy Z Fold 4] ultramag69:
Not gonna happen without root, even then might be difficult.

The Indian model is a F936B model. Trying to flash the firmware on it is like trying to flash IOS on an android.

Did see a way to change CSC in the forum however I believe you needed to have the compatible variant as it needed the OXM ROM flashed 1st.
[Samsung Galaxy Z Fold 4] Adv.Chirag:
Thanks for the reply. I am browsing the forums for a solution and so far have got nothing. I don't want to root the device as of now.
[Samsung Galaxy Z Fold 4] Emmanuel Spadafora:
Hii have a zfold f936b bought from eBay.

It says IMEI is 00000000 and when I insert sim nothing happens.

Any idea what are my options ?
[Samsung Galaxy Z Fold 4] iron@ss:
Your phone, F936U, is carrier locked to the U.S. network, AT&T, and if genuine, can only receive updates when connected on their network as unlike other models, AT&T issue their own firmware updates.

This model also has a locked bootloader which prevents the flashing of alternative stock firmware.

Also, it seems strange that a phone that was only launched in August 2022 would have a, "May", update. Install DevCheck, free from the Play Store and check if you have a clone phone.

[Samsung Galaxy Z Fold 4] iron@ss:
Seems genuine. Your mention of a May update threw me.

It is running the F936USQU1AVGA firmware which it was launched with and therefore, has never received an update.

However, it is still a bootloader locked model, even though you have it carrier unlocked. The only way to update it is to insert an AT&T SIM card and connect to their network in the US. Other than that, you will need to do a search to see if there are any custom ROM's that utilises the locked AT&T bootloader. Alternatively, just carry on using it as it is
[Samsung Galaxy Z Fold 4] Adv.Chirag:
Thanks for clearing these things for me. I appreciate it.
[Samsung Galaxy Z Fold 4] ultramag69:
No experience with AT&T but if they release their firmware online then you should be able to download & flash latest using ODIN.

Good Luck....
[Samsung Galaxy Z Fold 4] Adv.Chirag:
Thanks
[Samsung Galaxy Z Fold 4] adv.ravi:
i dont think its possible, India phone comes with 2 physical sim slots or an esim option for the second sim where as the AT&T which you and I have, comes only with single physical sim.
[Samsung Galaxy Z Fold 4] chakraa2:
Hi Chirag,

were you able to update your phone? I have the same model(SM-F936U/DS) and stuck with an old update and no new updates show up even though Andriod 13 has been rolled out for the Indian variants.

if there is no possibility of updating the phone then I might consider selling it! any help woud be appreciated.
[Samsung Galaxy Z Fold 4] Adv.Chirag:
There is no way I could find online to get the updates. Nothing works. The only way is to have US sim and be connected to AT&T network in US to get the update which is impossible. So I guess we are stuck with the old os version.
[Samsung Galaxy Z Fold 4] chakraa2:
Hi Chirag,

Thanks for the revert. Thats a bummer that we can't do anything with the update. I can still make my peace with the slow updates but having no updates especially the security updates is very concerning.

I will keep you posted in case I happen to come across any solution to this.

Regards,

Amit.
[Samsung Galaxy Z Fold 4] kripas:
may I ask how you able to unlock it? Who did you go to?
[Samsung Galaxy Z Fold 4] shorty9210:
I would say just start going through the different csc that's how I got mine to show the new up date then I just went back to gfc

I would say just start changing csc until it comes up that's how I got mine to show then January update and then I went back to GFC
[Samsung Galaxy Z Fold 4] chakraa2:
Hi, Do you mind listing out the csc version that you used? Also any tips on how to flash it would be appreciated . The lack of software update is really driving me nuts man.
[Samsung Galaxy Z Fold 4] chakraa2:
Hi Chirag,

I can confirm the method mentioned shorty9210 indeed works! I just changed the CSC to T-Mob and the updates have started flowing. Just use the samFw.com tool to change the CSC, you will get T-MOB logo once you have changed the CSC but the updates will come by. It didnt delete the data too. Couldnt be any happier!

Give it a shot!

Cheers,

Amit.
[Samsung Galaxy Z Fold 4] chakraa2:
you are a life saver sir! Thanks so much! I changed the csc to T-Mob and the updates are flowing! A quick question though do we need to change back and forth to GFC everytime theres an update? For now mine is at T-MOB.
[Samsung Galaxy Z Fold 4] Adv.Chirag:
Bro did it format the data?

and you used 3.31 version of the tool? also is 5g working?
[Samsung Galaxy Z Fold 4] chakraa2:
No I didnt do a factory reset ,neither did the tool. Yes I used version 3.31 only. I dont use 5g so cant comment on that buddy.
[Samsung Galaxy Z Fold 4] shorty9210:
Of course, but with that Said I wish I caught you guys in time, at this time I would say probably don't want to update to the latest update I finally figured out how to flash my U to U1 and I've been messing around I went back to xar csc and then flashed xar firmware and did the change csc and noticed a lot more compatible csc which I'm starting to believe that doesn't matter but one of the csc is WWD an turns out its a B model csc, I think I just found are backdoor into a unlocked bootloader without a paid service, more testing todo flashing B firmware has failed two tests gonna see if I could possibly make some combination firmwares, just have to figure out how to get the device not to switch the main service back to ATT soon as I put my sim back in, and to end this for the time being I recommend a reset on all csc changes and firmware flashs you tend not to get the whole effect, screenshot is after the sim was put back in I'll redo want I started and make sure I save my screenshot, as well another one with what my service, security, etc. I downgrade from VL9 to VKB when I was flashing the XAR firmware to just be safe, I'll make a more detailed post when I figure out more, FREEDOM IS COMING FOR SM-F936U and SM-F936U1 I'm sure of it!!!!

Any other questions feel free to reach out, until then!!!
[Samsung Galaxy Z Fold 4] shorty9210:
I'm in the USA and my 5g has never stopped with all the CSC changes I have done and still working fine with the WWD csc
[Samsung Galaxy Z Fold 4] chakraa2:
That sounds interesting! Please let me know how it goes. For now, I have updated to Android 13 with Jan'23 security patch and reverted back to GCF CSC from T-MOB CSC. Everything seems to be functioning fine for now.

I honestly got the phone for quite cheap albeit without warranty, so don't really mind this workaround of switching to some other CSC every time there's a security update which probably would be once a month.

Cheers!

Amit.
[Samsung Galaxy Z Fold 4] sagpatel:
So, I also have this ATT version of FOLD 4 which was gifted and my wife is using it in India.

So as I understand i just have to change the CSC to T-MOB using the tool and the updates will start flowing? Can I use the INS CSC, would that work? Or I should stick to country specific CSC?

I have come across a youtube video and the guy seems to offer to do it for USD 30 one time charge. He would do it via remote access to my pc so assuming he would do it the same way as mentioned here or am I missing something?

Thanks
[Samsung Galaxy Z Fold 4] chakraa2:
I wouldnt recommend getting it done from outside. Its a fairly easy process once you start using the tool, right now your csc would be GCF change it to T-MOb using the tool , let the updates come in till the jan'23 security patch post the Android 13 update,then revert back to GCF csc.

You might just have to check on what all is needed to make the phone get recognized once you plug in to the tool. USB debbugin needs to be on for one, please check on the others.

This was wonderful! You rock man! Thanks so much. Worked like a charm for me.
[Samsung Galaxy Z Fold 4] abadskp:
This was very helpful and I could fix mine. Thanks so much for the post and support. I changed my CSC to TMK and it worked! The updates are now smoothly rolling in. Will use it for the next couple of days and then post again. SamFw.com tool doesnt give a choice of CSC when used, but it does ask you to type and enter the CSC code. I did that and it worked instantly.
[Samsung Galaxy Z Fold 4] abadskp:
I am not very sure. But mine was TMK, when I searched with my software version...TMK is also Tmobile. So you need to verify.

tmk is not t-mobile tmk is metroPCS tmb is t-mob and updates flow in smooth
[Samsung Galaxy Z Fold 4] abadskp:
One query if you can help...I changed CSC to TMK (from GCF). What if I don't change it back to GCF? Also, is it possible or wiser to try another CSC like INS to activate call recorder and Samsung Pay. Thanks
[Samsung Galaxy Z Fold 4] abadskp:
Thanks man. Just for your info and for helping other memebers I would like to add that MetroPCS also runs under TMobile. Though using TMB as CSC will show you just TMB logo when you start phone, using TMK will show both Metro and TMobile logos and bloatware. Updates worked as smooth in it.
[Samsung Galaxy Z Fold 4] abadskp:
Thanks for sharing your exprience. Using SamFw.com tool I switched back to GCF, but realised that Samsung Members doesnt work with it. It shows error. I switched the CSC to XAA and everything worked just fine. It took not more than a minute! Amazing. BTW, SamFw website says my original CSC was CHA. Interesting!

Only thing I did not try was using INU as CSC. Didn't dare to try. But if it succeeds, I guess I should be able to access Samsung's built in call recorder and Samsung Pay. Has anyone tried it yet?
[Samsung Galaxy Z Fold 4] sagpatel:
You guys are amazing. Just changed CSC to TMB. Updated the phone to latest update (not UI 5.1), changed CSC back to GCF.

No data loss, everything seems to be fine. Only thing that while updating all updates had to be done one by one as in android 13 update with November security patch, then December security patch and finally January security patch. I was thinking it will come under a single update like what we have for iphones but was not the case.
[Samsung Galaxy Z Fold 4] sagpatel:
Can you please let me know how much you paid for the phone, I got it as a gift, so just wondering how much was spent on the phone.

Use samfw latest version, enable usb debugging, let the device trust. Connect it. Use change csc option and follow on screen instructions. Device will auto restart to changed version.

My GPS will not turn off in suspend mode, I have plenty GPS tracking sw running in background and it works well when in suspend, even iGo8. However iGo will keep flashing on screen when in suspend. Sometimes iGo8 will loose connection to GPS when resuming from suspend and must be restarted, it's just crappy software.

If you want to keep GPS chip running while Igo is in suspend mode try to add following lines in SYS.TXT file which is located in the main memory (not in SD card) My Device -> Program Files ->iGO8:
