Successful Recovery Note7 from last Samsung "Death Update" Disabled Battery Charging!

Ok, so here it goes, Im getting one more piece of Note7, addictive, I know... this piece has latest samsung's "Death Update" installed, thus its reportedly only working while plugged in with usb cable or charger but otherwise does not charge battery anywhere beyond 0%... so thats that.

My goal is to root this unit, and install custom rom (like hydra rom) and after probably reflash with ODIN with earlier version that did not have battery charging @ 0% cap , then again root the phone, install root package blocking program and just run stock rooted rom with updates disabled, thus having battery charging feature enabled. Ultimately my options of course are to attempt retrofit another battery to it like one discussed here in this thread:
https://forum.xda-developers.com/note-7/themes/note7-battery-swap-mod-note5-s6-s7e-t3545371

, since the model Im receiving has no warranty and it is already refunded unit to the original owner but was "written off" by samsung or whatever you call it, I dont care as long as I get it, I know me trading it in for S7e even aint an option so its going to be my test-unit for DIY and such.
Im wondering would charging features still be disabled if phone was powered via Download / Recovery modes? Anybody had first hand experience? Otherwise, is there anything else in place after the latest death update that prevents phone from being rooted and alternatively flashed with custom recovery/rom to enable charging?

Mega curious...

Hope ya'll having great weekend people

Not sure why you think that retrofitting a battery would allow the device to charge. The update on your device is what is preventing the charge cycle and also is stopping the device from using any radios.

You need to try to flash via Odin a complete rom, probably the last version that had the battery limited.

If you can manage this then you should be disable oem unlock under developer options and then install hydra by following the detailed instructions.

Battery retrofitting mod is not to get battery charging - is to keep note7 fail-proof, and with this specific unit that Im talking about it is especially the case only after getting it back to firmware that did not have it bricked.

I know about "OEM unlock" feature in dev mode is a must before any software tampering, so thats not an issue. I am aware phone works while on cable, so I should be able to navigate and activate OEM Unlock from dev menu, also I should be able to do straight ODIN flash with firmware that is of an earlier version without any battery cap's , so my question still remains - is there anything in this latest deadly update from samsung that prevents ODIN from flashing anything to the phone, or is it just charging orientated?

I have a Note 7 that's on the "Death update".

1) Phone cannot be charge in normal mode or download mode.
2) I did not check on whether it could still function with a cable plug in.
3) Attempting to flash older Samsung firmware from ODIN will not work. It will give some errors and stop there.
4) Could not flash anything through ODIN. BL, CSC, CP, AP could not be flash into the phone.
5) Could not flash recovery from ODIN either.
6) Enabling OEM unlock doesn't help in anything. See point 3 and 4 above.

Hope the above helps.

Ok, so got my disabled charging note7, it has about 24% battery remaining and it stays this way if I keep it plugged in on USB or on wireless charger.

I tried flashing TWRP both versions available, both had flashed OK with ODIN however, it still has standard recovery...? wtf...

I remember my S7edge did have very similar behavior, odin would flash TWRP just perfectly fine but when going in to recovery on the phone it still starts in standard recovery, and this would continue until I flashed CF-Autoroot IMG.TAR file , but this time I cannot find it anywhere for note7....

Im thinking trying KingoRoot or OneClickRoot tools but I wanna hold back a little before I launch on those.

Ok good news (so far) , flashed custom kernel via ODIN, worked, but now I figured phone takes charge again while phone is off just on USB, so charge disable mode is within latest kernel update only.

I can still enter my standard recovery and do all I want there (havent tried factory reset yet!)

When powered off from recovery, phone began charging! now I have noticed it went from 23% to 24% and it is showing it is charging, where as before it would vibrate for second when plugged in and then show battery symbol which soon after would go offline and phone would be unresponsive like it is not plugged in - in not charging state. So for now 1:0 me vs note7 :)


EDIT!

YESSS! IT IS CHARGING! NOW @ 26%!!!

Now @ 30% ... ok I should let it charge to 50% and then try perform more firmware DIY

ok, I will confess, I could not wait any longer, thought screw this sh*t, went in to recovery and wiped cache/factory reset, rebooted phone, then witness phone startup OK, welcome wizard started OK with 30% on battery and indicator on shows On-charge :) thought "yess!!!" , then I get this notification about battery is gonna run out and no longer recharge blah blah blah, but hey , it still charges and now Im at 33% :)

Yes, latest firmware and custom kernel and VIOLA , note7 is back in the game!

Also got this notification from device security thing asking me to reboot phone to try undo the changes... I guess I will not try just yet out of curiosity :) will try again to do TWRP reflash, this time it should work :)

Confirmed, now TWRP flash via ODIN worked liek a charm, so I should root via TWRP now and see if I can disable something in current latest software to disable these notifications :) playing around now

ok now rooted and lots knox stuff disabled with package disabler and etc, still getting this one notification about discharging battery warning when plugged in, anyone could advice me which file to edit in system root to bypass this?

Thanks

Wow, that's great. I've been trying for weeks but unable to get through to anything. Will it be possible to share on how you get to flash TWRP successfully? Thanks

I'm don't know about the editing stuff but if you could get TWRP to work, wouldn't it be simpler to flash custom ROM that already have KNOX etc disabled? :)

I was disabling all kind of random packages just to see what results will I get from doing it all , was expecting to somehow find package that relates to USB/wireless pad power circuit monitoring so I could work on it while maintaining the latest patched firmware but no nagging popups every time phone is powered on or plugged in to USB/wireles pad. Otherwise I observe phone is 99.99% perfect aside from the notification that I have described and security centre prompts warning time to time that device has been modified , click restart to undo-modification, which I actually tried and it undone-nothing, so it is permanently patched this way regardless what you try to do within the phone now.

I am in favor of keeping stock rom and stock appearance of note7 as much as possible.... dont know if it makes much sense but I love the way note7 is... with all functions working as much as possible as close to standard as much as possible, so thats why my reasoning trying to make this latest rom work.

I have few firmwares which were the original ones V.1 and V.2 but not V.3, which is what I have, so even if I install custom rom now, there is no way going back to factory firmware since V.3 full factory rom is nowhere to be found.

I am going to look in to ways on how to extract entire current firmware so I can go and learn a bit and maybe do few ROM builds myself, this is actually exciting now once I got this far.

only downside I see so far with current latest kill firmware and this patched kernel are those nagging notifications regardless battery charging to 100% ok, security center notification about modifications and about restart with attempt undoing them, which obviously will fail anyway anytime, and just now noticed it takes a little more time to activate wifi to show available networks, usually its instant, like 0.1second, and now its like 3-5 second delay once switch is toggled to ON position. Also, found out that when network sim card inserted, now phone prompts for network customization and asks to restart now or later to apply settings changes, and I tried restarting but this keeps coming on anyway, so finding the service package and disabling it solves this issue.

Besides no any network issues here, signal comes on every time I change sim cards around and all connectivity is there with data and all is OK, maybe try different kernel? I tried one with APO ,mine is European exynos SM-N930F model

This may help someone

Hi.
As I've read that there are people in the forum with problems after the last update from samsung, I decided to write my experience.

My first Note 7 was the Hong Kong version. It was amazing, because it had an fm radio built in, but of corse I couldn't flsh a costum rom on it, as there as none in the forum. In time, a gave up and send it to samsung, and I am glad for, since by now, I would have a death phone.

Anyway, after 2 months with a s7 edge, I found a person selling is international note 7, cause he would go to Brasil, and was afraid to had it apprehended at the aeroport. So I bought it, even with the limited charge at 60% problem.
First, I tried the Dr. Keatan rom, but the limited battery charge still persisted.
So I tried the TEKXodus rom, and I say its amazing.
My phone now as the batery charging to 100%, and even the shealth works fine, if you don't update it.
If it as an automatic update by google, just downgrad it and is fine.
When I received the samsung notification for the last update, I just needed to be sure that the update function was turn off, that the processes in the background were off too, and, with titanium backup, to freeze 2 "urgent update" apks.
Everything works fine.
So, for those who have problems, I recommend the TEKXodus rom.
Best regards
