This is a common problem form Lipo and Li battreis. When the shelf time is so long - the battery Voltage drops and it means the resistance goes very high. So there is a risk of fire if the power pass by upon connecting it to a power supply. Therefore, the little Capacitor behind the unit blocks all the current. I think Ledger changed this in the new firmware. So the tolerance is much more than before - and battery can charge now easier.

I must say I hear much less these days that this problem happens. And if a device has a problem, without changing the battery, I simply upgrade the firmware and problem simply gets solved.
Again, I am (somehow) expert on this, and I can imagine not everybody is familiar to do it.
I am not a technician, so I can't comment on whether or not your fix is good enough. What I can say is that Ledger obviously made physical (hardware) changes to their new black box version of the Nano X in the areas around the battery and connectors. So I don't think the problem can be fixed with just a firmware upgrade.

If you have so much experience in fixing these devices and are confident your solution works, make a video of a faulty device that you fixed in the way you explained it. Post it here so we can watch and send it to Ledger as well. Who knows, there might even be a reward for you if they like it. 

Sounds like a good idea. I will make the video first. Post it on youtube and share it wit you guys...give me like 10 days...I will work it out!

You do not own your private key or 12/18/24 recovery phrase: I am afraid you do not own your crypto anymore.
OP wrote in his second post that he recovered his wallet with the recovery phrase, but after LL performed the necessary scans, it didn't find any of his accounts. He might have made a mistake when writing down some of his seed words which resulted in the recovery of an empty wallet or he is using a completely different recovery phrase that never held any funds in the first place. Another possibility is that he downloaded a fake Ledger Live app, or that he forgot that his original seed was extended with a passphrase. Since OP never came back after his last post on the forum, we will never know how this ended and if he regained access to his crypto.

Is there any Fake Ledger Live app that can work with the hardware wallet? If so, can you send me a link of which to have a look at?

3) Lets agree that Ledger is strongest in this market and so far most successful.
It's your personal opinion that they are the strongest. They are certainly the most successful in terms of sold units and generated profit. They also have the best marketing and invest a great deal on that front.  


YES they are most Profitable!


5) I assume what I did, to share my knowledge with other readers in the forum is exactly the intention of these kind of forums. If you do not like my proposed method, you can simply ignore it.
You are free to write whatever you want, no matter what someone else says or thinks about it. But I am asking you again. Is this just theory, or have you tried it out yourself or maybe you know someone who has?

Answer to your question is "Yes". I tried / applied it several times on different devices including Ledger Nano X. At least I have repaired more than 50 LNX units (you may ask why: answer comes later). as well as Bluetooth headphones.
I am an electronic technician and I live in a country that Ledger does not ship product to (I mean Directly).
So traders brings the product on behalf of Ledger and resell. In this situation, consumer can not return the product to Ledger if it has a battery problem. Due to reasons:
1) they do not have any proof of purchase from Ledger
2) Ledger can not send them a return label, as Ledger does not have any shipping service to Iran.

So I have been working with local sellers such as: https://walletjoo.com/
They are not official seller - as ledger has not got one in Iran - but they resell genuine product.  
Even there is Ledger repair service in Iran, that provides all the local supports - including all the genuine parts.

Another crazy point is that you can not upgrade the device firmware with your iPhone, or Android!! while the product is meant to be used only with a mobile phone. I asked ledger support what to do, if one does not have a laptop? Are you going to send me one?  Grin they reacted , no you have to borrow one!! Stupid.

Lets be a bit structured:

1) I am not not representing Ledger. I have no common interest with Ledger to clean their a...!
2) I hope also others who are attacking to me are also not having interest with Ledge competition.
3) Lets agree that Ledger is strongest in this market and so far most successful.
4) What I shared is here with you guys, free, and honest, was only a practical way to solve the problem. Maybe the term of extremely simple was not very correct that people here are not expert with electronics. I only advise that for those who know basics around electroncis. Otherwise please do not open your device.
5) I assume what I did, to share my knowledge with other readers in the forum is exactly the intention of these kind of forums. If you do not like my proposed method, you can simply ignore it. But you can not ask me not to share it.
Ledger is not going to make a booklet / manual along with product for this type of solution. and I am sure it was a joke by others members.

It is not a suprise, as reserachers showed that 20% or more of BTCs are lost because ppl may not know about it Sad(

Hi all;

Do not panic! I have posted earlier today here: It is very simple to solve this problem by yourself. I have posted here below how to do so.

Solving the problem of Ledger Nano X is extremely simple!!!
Why are you making so much sorties around it?

Battries are not dead. They only need a so called Jump Start!

Physics around it is extremely simple: Due to whatever reason (for example long time shelf time) the voltage drops far below 3.7 v. That means natural Resistance of battery goes too high. It does not allow the motherboard to pass any current - sort of safety reason.

Sometimes, all you need is a little push to really get going, and for electronics, that push is called a jump-start. Unless you have incredible driving luck, you've probably had to jump-start a car once or twice, and the process for a lithium-ion battery is pretty similar (but not quite as dangerous).

Remove the battery from the Ledger, noting the negative and positive feeds. Find a USB cord you don't mind sacrificing and cut off the smaller end or B connector, exposing the positive  and negative  wires . Also you can connect your battery to another battery with same range of voltage 3.7 v I guess.

If you google it, it is a known practice for all Li batteries - like Bluetooth headphones etc.

If you need further help, simply drop me a text - I''ll be glad to help you.
