Hi,

I wonder since there's so much effort on rooting several devices, is there any thread about hardware-rooting the cheap Amazon Fire 7" Tablet?

I have all my old tablets rooted and replaced before Amazon's exploitable bugs were closed.

However I would be interested in a few more tablets from time to time.

Recently I had to recover one defect tablet, and desoldered the eMMc.

I have jumpwired the chip with a micro-sd card adapter (4bit transfer) and retrieved clean partitions.

Interesting sidenote:

There must be a big bug in the Linux sdcard driver support, when I have jumpwired only 1bit transfer the sdcard shown on the linux system contained the content of my harddisk instead of the eMMc.

[edit - after writing all that already] reconnecting the jumpwired 4bit microsd card resulted in further linux kernel driver issues

Only a clean linux boot and attaching the microsd/emmc card once works without any problem (I have pulled all my old apps and data without any problem)

According to the datasheet of the 8gb flash the flash can handle 3.3v (which makes it ideally for a micro-sd adapter

(eg. https://www.amazon.de/SanDisk-Micro-SD-Adapter-auf-SD/dp/B001PFAF9U I have just cut half of the top and soldered the pins)

eMMC Datasheet:

https://www.verical.com/datasheet/samsung-module-klmag2gend-b031-1212321.pdf

Flash used in the Kindle Fire 7" Tablet KLM8G1GEND (pinout is the same as for the KLMAG2GEND)

Did anyone already try to jumpwire a microsd card directly with the testpoints?

- CMD

- DATA0

- CLOCK

- 1v8

- 3v3

pins are exposed on the small firetv 7" tablet.

I don't have equipment for reballing here so I'm a bit limited with my ability to do further testing.
[Fire General] tf101crasher:
My internet is terrible at the moment... I'm having some issues with uploading the pictures

just another try here.

[ok you can delete this reply, I saw that the first post is ok everything's so slow here due to my unreliable DSL ...]
[Fire General] Rortiz2:
In this I can not help you because I'm not good at hardware mods . Maybe [MENTION=9348949]<br />[/MENTION] can help you.
[Fire General] ANDROID2468:
I'm not an expert in this or anything but I don't think you have to desolder the emmc. [MENTION=9348949]<br />[/MENTION] made a hardmod to root the he 8 here. he soldered to test pads. Maybe we can do something similar to the hd 7. The test pads may or may not be in the same spots as the hd 8.
[Fire General] hwmod:
You can compare your outcome with my attempts back in September, I had some success initially.

In subsequent testing I destroyed/ruined the DAT0 pad on the PCB and should abandon my investigation.

Also that was the only Fire 7" 5th Generation I had to do my investigation, so I lost my unique testing tablet.

Here are the links to the information I could gather and a picture with the pads:

* https://xdaforums.com/showpost.php?p=77501192&postcount=365

* https://xdaforums.com/showpost.php?p=77886908&postcount=381

After that I bought also a Fire 7" 7th Gen. and a friend gifted me with a broken Fire 7" tablet, also a 7th Gen.

So I started to trace-out the pads for doing the same tests, as you have come to know a slow and tedious process.

I am almost finished, I found almost all the needed signals CMD, DAT0, 3.3V and 1.8V I am only missing the CLOCK line.

The EMMC is a 16GB Samsung KMFE10012M-B214 which is a 221 BGA package.

One trick someone suggested, if the reading seems to fail, is to have 100 ohm pull-up resistors to 1.8V for both CMD and DAT0 lines.

I am obviously interested in your testing, so please report your success and your setup as detailed as you can, possibly with photos.

One interesting improvement is that you are taking the 1.8Vccq from a resistor which is much more solid then the pad I was using.

In fact I would suggest to avoid pads at any cost if there are alternative soldering points, these pads are easily ripped of the PCB by

sudden pulls of the connected cable or too many attempt with the soldering iron, due to the heat and too small nearby traces.

Well ... happy hacking I wish you success !

.:HWMOD:.
[Fire General] xyz`:
That's very strange. Can you post a picture of your fire 7th gen? I have a fire 7 7th gen too, and the emmc chip is skhynix, not samsung. Also it is a hybrid chip combining both dram and emmc in one. There's only one testpoint, here's my picture: https://i.imgur.com/fBx88CN.jpg Mine's 8gb model though, so maybe they use completely different PCB layouts?
[Fire General] hwmod:
Here are the pictures you requested (external to XDA):

The front & back of the FIre 7" 7th Generation PCB.

I am sure the 16GB LpDDR EMMC in my PCB is a Samsung KMFE10012M-B241 (moviNAND series).

Attached to this message you can find relevant EMMC pictures which leaves no doubts about that.

Your pictures are taken from a different angle but to me it looks like they are the same PCB.

As you said, it may be that the 8GB and 16GB EMMC versions have different vendor/manufacturer.

Nothing strange about that.

.:HWMOD:.
[Fire General] xyz`:
Oh yeah my bad I didn't realize it was also a hybrid chip in the 16gb case.
[Fire General] tf101crasher:
Can you take the shielding off and take another photo?

Putting some needle adapter on the traces shouldn't be a problem.

I won't be here for 4 month now ... too bad that I started to look at that so late.
[Fire General] xyz`:
If you short the test point under the shield (which is the eMMC CMD line) to ground, you can put the bootrom into download mode and exploit it the same way I did in https://xdaforums.com/hd8-hd10/orig-development/fire-hd-8-2018-downgrade-unlock-root-t3894256. No need to solder the adapter.
[Fire General] hwmod:
On these PCB the shielding is not removable easily it is soldered to the PCB and must be cut off with a sharp and robust enough hand cutter with small/thin blades.

Since the board was not functional, I did the job with an electric multifunction rotary cutter/grinder tool, consider the danger of cutting components or traces.

Hot air gun would not fit the job since the heat needed is likely to melt all the components around the PCB.

However attached here is a photo of a PCB with part of the shielding removed (not the same PCB in previous photos).

.:HWMOD:.
[Fire General] ANDROID2468:
I took the risk and removed the shield but not without board damage. luckily it still works

https://imgur.com/a/YRxzM6y

I used a pocket knife and needle nose pliers to remove my shield
[Fire General] ANDROID2468:

[Fire General] Rortiz2:
But where have you connected? What is the other pin?

EDIT: I confirm that it can be done without removing the shield. You need to have a little precision to put the metal through a hole (see attatchments). The problem is that I do not know where the other point is.
[Fire General] xyz`:
The other end is the ground plane, so for example the metal shield above it would work.
[Fire General] hwmod:
Yes that is the pin that should be temporarily connected to GND (the shield for example).

However FYI that pin is the CMD signal not the CLK signal, it doesn't make any difference in our case.

I wanted to underline the fact because I believe I have seen reference to it as the CLK (clock signal).

.:HWMOD:.
[Fire General] monkmandolins:
Hard Bricked

I figured I would try the method of using a metal object under the shield to see if it would work. This is an extra tablet for me, so I wanted to see what would happen. I had issues with the TTY serial port on my Ubuntu setup. The tablet kept turning on after being plugged in to USB. At some point it ceased to turn on at all. I shorted something.

I will say that the cover of this tablet is exceedingly easy to remove and reinstall without any damage to the tablet whatsoever. It is clipped on without glue.

If I had another tablet to mess with, I would use a dremel and trim away a small part of the shield over the solder point in question.

Thank you all for your fascinating and hard work. I have enjoyed following these threads.

[Samsung Galaxy S9+ Guides, News, & Discussion] call_of_ktulu25:
So its been 7 days since I updated my Galaxy S9 + to the official Android 9 Pie. I am loving it overall. I think moving the UI elements to the bottom was a nice touch, leaning towards one hand operation. I panicked at first seeing all that wasted space but once you scroll down, it returns to normal. Love the Dark mode but not fond of the quick panel icons, no big deal. So far i had notice these bugs or feature omissions:

• No inertia scrolling in recent Apps (no rubber band effect). Scrolling is just one at a time.

• Some animation Jittering and Stuttering in the UI but less frequent now as the OS settled.

• The options when you click the middle of the divider in split screen view is not working/showing up.

• Good lock Apps stopped working except One Hand Operation

• Good Lock One hand operation is miles better IMO than the new gesture system, even better than the stock pie gestures and Apple gestures. Why don't they just bake One hand operation into the system is beyond me. But at least we can hide the nav bar natively now. One hand operation can co-exist with default gestures without affecting each other.

• Finder seems slow in Pie than in Oreo. It doesn't show the most recent search (by showing the app icons) i made and often requires me to tap twice the name of the app then another selection of related things about that app and that is where the icon will appear. Multiple taps instead of one.

• Dolby Atmos for games seems missing

• Swiping down in the homescreen to show notifications Panel needs a long swipe down as oppose to before needs only a small swipe down.

• Gallery - some very high resolution photos are not displayed properly. You can see jagged/rough lines all through out. But when you set the photo into wallpaper, homescreen shows the same photos correctly.

• Samsung Internet - PiP button is gone and couldn't find it anymore even in settings.

• Keyboard - when gestures are on (nav bar is hidden) and keyboard is showing there is a large gap at the bottom as if the nav bar is still there

• Network name overlaps with notification settings in the notifications panel if you have many notifications.
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
1. Scrolling between recents doesn't stop at each app in recents on the k list recent C builds.

2. Don't atmos for games was reported as being somewhere different. I don't use it so I'm not sure where.

3. The keyboard gap is intentional. It's too help avoid hitting home when using space bar. If you use swiftkey there is no gap. I got home often when not intending to when using space bar.

4. Nav Gestures are appreciated here. No reason for something new when bar / gestures are fine. It's nice there's another option, but no reason it should be default IMHO.
[Samsung Galaxy S9+ Guides, News, & Discussion] call_of_ktulu25:
1. How about in yours? So looks like it was not implemented in the official and not just me.

2. I set atmos to auto so i guess it automatically set it for games, movies, and music, etc. But no option for games only. It is in Sounds and Vibration>Advanced Sound Settings>Sound Quality and Effects

3. Ok

4. Ok to each their own. One Hand Operation + was released since June 2018 along with other Good lock Apps so its not really new. It gives us a taste of the upcoming Pie update. And as it name says, it allows you to use the left and right edges for gestures in one hand. Try to reach the nav bar and do the new default gestures with your thumb with one hand and you'll know what I mean.
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
1. Yes, in the Z build I used it would stop at each app. I hated it. On CSA3 it works like in oreo.

2. I'm not sure where I read it, but there was something specific about Dolby for gaming mode being hidden off somewhere else. I didn't put much thought into it since I don't game. Could have even been in the pie thread for the 965F.

4. I do occasionally have a problem reaching that one button with my thumb in one handed mode. I've gotten used to it to be honest. The S9+ isn't the biggest device I've owned. The v20 and Nexus 6 were bigger.

That said, I can see the value in more one handed items. Choice is definitely a good thing. I'm just happy with the current implementation.

On the flip side, Samsung (and others) are always out to take more market share. I think they are seeing the error made by Apple. You can't raise prices and force unwanted changes on customers. Sticking with a more established bar / gestures would be the way I'd go. When you try to get new users, you want to give them something fairly familiar.

Just my opinion though.....
[Samsung Galaxy S9+ Guides, News, & Discussion] _Usama_:
Its terrible IMO. Probably the worst implementation of Pie. Samsung went from having the best skin to the worst now.

After Factory Reset

Deal Breakers :-

1:- Recents animation is worse than 200$ phone. When u are inside an app and press or trigger recents menu. It glitches and lags like everytime. Its only smooth when u are in the homescreen.

2:- Device Care Stuck at 95% for a long time before it shows status.

3:- Launcher sometimes lags when scrolling between pages.

4:- Scrolling lag in apps like reddit and playstore. Oreo scrolling was smooth.

Lag is the major issue in pie however IMO the icons are literally the worst now too. Experience Ui icons were 100x better.

I didn't factory reset, but that was the most annoying the recents scrolling. Animations in almost everywhere were lagging but as the OS settled and after a few reboots, its fluid 98% of the time. But still, i missed oreo due to its fluidity and icons and quick panel icons. No issues with device care.

Well... I am thinking of going back to Oreo acually..

1.Hangs, reboots

2.Stock launcher has this huge space underneath icons even with gestures on, same space thing on stock keyboard(using gboard removes it on keyboard)

3.My games dont launch like they did on Oreo

4.Notifications are messed up, constant connect/disconnect on my gear 3, even when turned of they show sometimes.

Maybe Goodlock 2019 will keep me on 9... but atm im very tempted to go back to 8.0 :/

Has anyone noticed the volume is so much quieter now? Looking for solutions. I'm not hard of hearing but I can barely hear my sounds anymore.

Now I have to remember to turn off wifi and turn on Bluetooth and vice versa multiple times a day to keep my battery in check. PITA. But that is negligible to the volume issue.

[Galaxy Tab S Q&A, Help & Troubleshooting] saintjules:
In the last 6 months or so I have been experiencing frequent wifi issues, regardless of the custom ROM I'm using. Usually some time after a new installation I am unable to connect to the networks I normally use (my home network and the one at work which uses a proxy server). No matter what I do (clear cache, factory reset, change ROM...) the problem persists. In settings a number of random messages are given: secured, disabled, authentication problem, etc. Every now and then I can get a connection (never at work though) but it doesn't last long. Any help for troubleshooting this would be appreciated. I hope it isn't hardware failure since I'm still enjoyng this tablet after all these years!
[Galaxy Tab S Q&A, Help & Troubleshooting] rp_63:
Mine started having wifi issues off and on a couple of weeks ago. The wifi started to not turn back on after waking it up, at first just in manually turning it off and then back on seemed to work. Last Friday it just wouldn't stay on at all. I would go to the wifi in settings, it sometimes would get stuck saying turning on. I finally did a factory reset on it, it at first seemed to fix the problem, even spent a couple of hours trying to get everything set back up. Then the problem returned, it just keeps turning the wifi off, if i can even get it to turn on at all. I was going to try and use my phone as a hotspot through Bluetooth (not sure if i can or jot, never tried before), but even the Bluetooth won't stay on. So Sunday, after spending way to many hours fighting with it, i went out and got a new tablet.
