Help: Phone is in bootloop - Lenovo P780

Hi,
I am using 8 GB version. I had rooted it some time back. Now since the phone was hanging few times, i did factory reset (as i understand now, may be was not a good option). Phone did boot one or two times since then, but crashed immediately. Afterwords, phone gets stuck at lenovo logo if I try rebooting.
I am a novice in this, so couldn't figure out the exact process (from the numerous related threads). Would greatly appreciate any help.

Hi. If its not too late look what you must do(this are some guide lines you must read alot in Q&A section):
1. First you must install Lenovo drivers. At the bottom of the page.
2. Now you must know if you have stock or custom recovery. To do that you must power down your phone and start with volume - and + and power buttons pressed all toghether. The phone must start in something called TWRP, CWM or stock recovery witch is very simple.
3. from there are few choices: go to wipe and wipe cache and data then reboot and see what happent, maybe the phone will start.... or you must flash another custom firmware and the phone will allso start. For custom firmware you must know and tell us what was your base firmware: chinese or ROW. ORRRR.... flash with SP Flash Tool another base firmware .... This is more difficult. Needs some basic knowledge about flashing.
Good Luck.

Thanks a lot Stympy ! The Q &A section was very helpful and I was able to figure out the way. In fact, the google pay store issue (i had messaged you about) was after flashing S228 ROW version.

[Q] tried to root i777, now stuck at galaxy s2 with triangle and i900 screen

Hello first time rooting this phone. Its a SGH-I777. I used the guide from galaxys2root.com/. At first it didnt work because my computer didnt recongnize my phone. I tried a different computer and it seemed successful until it rebooted. When the phone rebooted it did nothing but stay on the first screen. I still have the ability to get into Odin mode(download mode), but that is it. When i put the phone in download mode and use Odin it allows me to download the "zimage" but after rebooting it is the same exact thing. I have tried the one click root, one click factory restore. Tried restoring it on Kies. and nothing work took it to a store and the guy said he tried but it would stop in the middle of the download the only option i had with him was purchasing a new mother board for $80. Does anyone have a solution that can help me fix my phone.
Before i attempted to root it, it had OS 2.3.6 with kernal 2.6.35.7.
Go to the development section and read the stickies. There you will find stock rooted packages you can flash with Odin.

@jmula,
Enter recovery and perform a wipe data/factory reset. That may clear the failure to boot. If not you'll need to flash back to stock and start over.
The yellow trangle is a result of flashing a custom kernel using Odin or Heimdall, and is expected. You are not the first person having problems with the tools provided by GalaxyS2Root. In the future, I would recommend you avoid his site.
And... as suggested, read and study till you understand the basics. Then if you have questions, feel free to ask.

the only option that i have is to put the phone in download mode. when i try to download any kernel it reboots and does not go past the booting screen with the triangle.

You should be able to enter recovery. Hold down all three buttons, vol+ vol- and pwr, continuously until the phone boots into recovery. It could take 10 or 15 seconds or more. If that is unsuccessful, then since you can enter download mode, you will need to flash back to stock, or stock plus root. That is not just a kernel, but the entire package. Please see the links in my sig for instructions.
The dropbox links in the download repository are temporarily suspended until probably Monday night or Tuesday as someone abused and over-downloaded. But the hotfile links still work.

The next thing I would suggest is to try and flash the UCKH7 full stock package with bootloaders. However, as the dropbox links in the download repository are currently suspended, you will have to download it from SamFirmware. To be able to download, you will need to register for free if you havn't already. Search sgh-i777 in the upper right hand corner of the page, then download the I777UCKH7 version. Let us know if that will flash.
Ok it finally wokred after countless times of changing usb ports. I used the one click recovery. It restroed my phone to 2.3.4 i had 2.3.6. I tried to update by kies to 4.01 and it didnt work. Kies froze. The queestion is how do i safltey root the phone?

Flash a .tar version of a custom kernel with Odin. I always use an old siyah.tar, but that's just me. There are other methods floating around but that's the quickest and easiest for me. I think there's an old entropy dd.tar around somewhere too. But just flash it through Odin and you're good to go, assuming you flashed one for your version of android. If you just want to get into recovery to flash something this works as well.
There may be links to tar versions of the kernels in creepy's sig I don't remember offhand.
Ok since i do not want to brick my phone again where it is just stuck at the boot loop. I tried looking for ways to root and when i tried some of them my phone went back to the problem it had it the beginning. Should i just call it quits or do you guys have a guide?

Give up???
I personally don't think flashing a kernel with odin is the best way to root. It increments the flash counter, for one thing, though I'm not sure how many people care about that anymore. I would suggest that you use the stock plus root package to root the phone with odin. See the links in my sig.
Guide... did someone say guide?
Feeling the pain....

First, to Creepy....you've been a great resource here and I read a lot of what you post and you got me out of the very jam being discussed here. I made the mistake of trying to root via the galaxys2root.com site (actually, I thought it was a different site...was redirected), got the i9100 screen and a boot loop...couldn't go anywhere. I came back here and found resources eventually unrooting my phone all the way back to 2.3.4, then moved to 2.3.6, then the stock android 4.0.3 which updated to 4.0.4.
But I still want to root (4.0.4 shuts itself down A LOT...more than 4.0.3) and I have a Galaxy note 10.1 with JB 4.1.2 and I LOVE IT! I feel on a mission to get rooted and try out some of the JB roms I see talked about here, but can't seem to find the best way to root. I've heard exynosabuse referenced here (no links to it though) and I don't want to use the wrong one and mess up my phone. I've been reading for weeks here and there's obviously a lot of great material, but I'm not sure which material is critical to understand, and which is "nice to know" but might not even apply, and which material isn't even right. Very frustrating.

The ExynosAbuse application is the only practical way to root 4.0.4 without changing base. You can download it as an attachment in the OP of the developer's thread, but read through the thread first to understand its limitations and risks.
Alternatively, you could flash 4.0.3 plus root from the development forum. If you choose that route, please read the thread to understand how to install a custom kernel, which is recommended whether you plan to install a custom firmware or not. The custom kernel will contain ClockworkMod Recovery so you can flash the firmware of your choice if you wish.
There are really several routes you could choose. All of them work. Another would be to flash back to stock Gingerbread plus root. For that see my guide How to Flash Custom Binaries Without Ever Incrementing the Flash counter!! (link in sig)
Hmmmmm..
Well, I see that their are many, more experienced than me following this thread and my following comment is not meant to jump on the knowledge train here, but............... I had the same event happen as the orig poster earlier today. I had installed an app,I then rebooted and it got a bit stuck on the Galaxy SII, What I did was go into recovery ,cleared the Dalvik cache and that is all I cleared. Then I re-installed the RR Rom .rar, which I keep on my SD, over everything and rebooted, it came back as it was 4 mins before . All I did after, was do a system restore(only) using Titanium BU. So when I see all the "clear and restore this and that" I started to doubt some of the more experienced than I. My 2 cents is, that, if one does not know EXACTLY ,how to correct an issue,leave it for our more knowledgeable brothers and sisters.
If I am wrong ,please except my appology.

I don't know what you're trying to get across here. Yes, restoring a backup nandroid works. Yes, you can try wiping cache and dalvik to see if it fixes an issue. Yes you can restore apps via titanium backup. All these things are indeed true.

And yet you say, "All I did after, was do a system restore(only) using Titanium BU." This may have worked for you, but this is an absolute recipe for disaster, and should not be given as a recommendation.
And further, from what you say, you did not have the "same event happen as the orig poster." Instead you "had installed an app,I then rebooted and it got a bit stuck on the Galaxy SII." This is by far not the same as trying to root with a tool from GalaxyS2Root.

HELP Rooted and Installed ARHD Now Phone Hangs at Quietly Brilliant

Sorry I'm a noob at all of this. Successfully rooted my phone today thanks to Honsoon2000's excellent tutorial and toolkit. Then I went to install Android Revolution, which appeared to go successfully and then after I flashed the kernel the phone wouldn't load and just hangs at the quietly brilliant screen. I followed Honsoon's tutorial to the T (or so I thought) and everything went perfectly until right at the end when I flashed the kernel. I can make it back to the bootloader screen though it says "failed to load usb master mode". I can still make it into fastboot and recovery mode...tried recovery, and the process seemed to go sucessfully, but the phone still wouldn't load after...tried reinstalling ARHD-- it's still on the sd card and the install procedure still goes off without a hitch, but the phone still won't load. I've searched around and tried everything I can, to no avail. Any help would be muchly appreciated, and I apologize in advance for being a noob wasting people's time.
Edit: For example, when I follow the steps outlined in the FAQ it asks me to enter the command 'fastboot flash boot boot.img' , but when I do it says 'error: cannot load boot.img'.
Edit 2: So I put my boot.img file from Android Revolution into the data directory of the rooting toolkit and was able to complete the above flashboot command. I was also able to install the ROM off my SD card...however the phone still hangs on the Quietly Brilliant screen...I can't even power the phone down...whenever I try it just reboots...frustrating...really hoping someone can help me...cheers.
Before you begin, make sure that the drivers for the One X+ are installed.
Place the boot image being used on the computer's hard drive.
Boot in to recovery and flash the ROM.
When that is done, boot in to bootloader and connect the phone to the PC via a USB cable.
If the phone isn't in fastboot mode already, use the volume keys to highlight the word "fastboot", then press the power button.
Now, there should be text at the bootloader screen that says "Fastboot USB".
Finally, use the toolkit or command line and flash the kernel with the fastboot command.
This should successfully flash the ROM and the kernel. Make sure you full wipe before flashing a new ROM. If you can't seem to get the new ROM booting, the final choice is to relock the bootloader and run a RUU.
Which phone version you do own? International or AT&T / TELUS?
Did you flashed the correspondant boot.img? Did you cleared the cache? ( fastboot erase cache)
I'm trying to run an RUU but it keeps saying the battery isn't charged enough to flash anything...and this after it's been plugged in all day. Oh dear I think my phone might be done...really sucks :/
Also, it won't let me power the phone down-- every time i try it shuts the phone off briefly and then opens back up to the bootloader screen.
Fixed thanks to sarcasticphoenix. Cheers.
OK so I've tried 3 times to flash a new ROM onto my phone (Android Revolution twice and Eleganzia once) using Honsoon's toolkit...I've followed every instruction to the T as far as I can tell and all 3 times the process has gone perfectly right until the end when I flash the kernel...after that when I reboot the phone it just hangs at the Quietly Brilliant screen. I know how to relock the bootloader, flash the custom rom and get my phone back...but I really want to know what I'm doing wrong so I can install a custom ROM. I know I'm using the right ROM for my phone and am wondering what gives. Being driven crazy here...any ideas what's going wrong here would be helpful. BTW on the last attempt right after I finished and the phone hung I went into the boot loader and followed the instructions in the FAQ for fixing a bootloop...still nothing.
Edit: Solved my problem-- I managed to successfully load eleganzia...the only thing i did differently the last time was flash the kernel BEFORE installing the ROM off the SD card.

That's usually what I do first, flash the kernel and then install the zip via recovery
Sent from my HTC One X+ using xda premium
Which kernel are you referring too? Actually there is one or two kernels available but only for the International version, not the AT&T/TELUS which you seem to have.
I strongly suspect that your boot looping was because you didn't flash the boot.img file correctly or not at all. And you don't seem to install the good ROM version for your phone.
Elegancia has two ROM versions one for International and one for AT&T/TELUS users.
ARHD is for International users.
Please read Q12 of the FAQ.

Lol...yeah I don`t know how I missed that. I ended up getting elegancia successfully flashed and loaded so all is well. In retrospect this was a good experience because there`s nothing like having to get yourself unforked from a bad situation to gain an understanding of what`s going on. Cheers.
I have a couple questions and since I`m not allowed to post yet in the elegancia thread I'll try in this thread first:
1) An elegancia question: Is there a way (widget) to toggle data roaming on and off in this ROM?
2) Is there a way to tweak settings (transparent pull down, selection of launcher etc.) without wiping and reflashing the ROM?
3) What are people's favorite launcher for that ROM? I tried Atom but it was just a guess because I hadn't heard of any of them. I like it so far but am curious about the others.

Recover data from T399 with corrupted cache

I'm trying to get the user files off a phone with corrupted cache. When booted normally, it gets stuck on the white T-Mobile splash screen. When booting into recovery, I get an error about the cache and the phone restarts without loading into recovery. Screenshots attached.
I can get into download mode fine.
Using Odin to flash a custom recovery gives me the PASS message, but when I restart the phone, the stock recovery is still there with the same error message. I've tried TWRP and CWM.
I am hesitant to try flashing a custom ROM because I don't want to lose the data. The phone is not important, but the data is.

Dont try flashing a custom ROM on to the phone. Try flash the stock ROM through the lastest odin with the lastest drivers and let me know how that works out for ya. Unless that wipes the phone ( havent used it in quite some time) then I have no idea man.
I tried flashing the T399UVUAMJ4 ROM throught Odin. It went through the entire process and rebooted, but nothing changed. Does this mean the bootloader is locked?

I'm not sure maybe want to ask someone else I'm not as experienced as some people on here. Sorry man goodluck
I hope someone can help you out. I would say your cache partition somehow got renamed but I'm not sure if thats possible and if so how to fix it. Maybe someone with ADB knowledge can help?
Also what TWRP were you trying to install? I've had problems when I tried to flash older versions
okay so here is a site with the original firmware for the phone. It has both the t399 and the t399n for odin. It has them labeled so its not too confusing lol. http://forum.gsmhosting.com/vbb/f200/samsung-t399n-metro-pcs-firmware-here-1899016/
find the one for the t399, flash it with odin. this will fully restore your phone. HOPEFULLY it will be able to save the data. I know you said you did this before but I'm not sure if it was just system or everything like here.

So I tried the T399 files. Flashed with no errors, but when it reboots everything is still the same. I've even tried flashing from another computer. Mind boggling!

Thanks for the quick reply. Its a shame to hear that it didn't work
How did you come to this? as to me it seems the partions have be modified hence why giving those errors I seen similar errors to when users change cache sizes which tends to brick device or from using incorrect pit files.
You never be able to recover data from flashing Odin may be slim chance by custom Rom thru recovery if was a bkup of original system and not selecting data your old data may conflict causing either bootloop or basically stuck on splash screen.
If you was ever able to best way to pull data from device would be thru adb may have a chance.
This phone belongs to a friend of a friend. They said they brought it to T-Mo because it hung up during boot. The store worked on it for a few minutes, but couldn't get it to boot up either. When I tried to go into recovery, they said the store already went into that screen too. They have since bought a new phone, but would like to get the photos off it if possible. They never had an SD card so it's still on the device.
At the moment, I can just go into download mode. I was hoping to flash a custom recovery so I might possibly be able to ADB from there since it won't load the stock recovery.
I have a very similar issue but without "cache error messages". The phone (Samsung Galaxy Light with stock ROM and TWRP) just reboots no matter what I try to flash into it.
It does it while "drawing" the Samsung Logo animation (blue ring that gets created revealing the word samsung), so after the white wrintings of the phone name.
My attempts so far:
1. Flashed newer version of TWRP
2. Flashed CWM
3. Flashed two different versions of stock ROM (the original one and the one that T-Mobile released when upgraded to latest jelly Bean)
4. Flashed a custom ROM (Light ROM found here which is based on the stock one).
EVERY TIME the outcome was the same:
Phone reboots right after the phone name (written in white) while the Samsung animation starts. It just stops while the blue oval begins to appear. If I try to boot into recovery (via home/power/volume up combo) it shows the TWRP splash screen but it reboots right after and this happened even after I flashed (successfully according to Odin) CWM.
It really looks like I did nothing so far but I can assure it's not the first time I use Odin (4 different versions) to flash a custom recovery or a ROM. I did it successfully on other 4 different phones (all samsung).
On this same phone I did it the first time when flashed TWRP in order to root it via recovery.
I have no idea what to do next. I was thinking about using adb in order to wipe all the caches (dalvik included) but it looks like the phone can't be recognized unless I boot it into recovery mode (adb get-state returns "unknown") and I don't think I can do anything in Download mode which is the only mode I can enter apparently.
I was hoping someone here can help me to spare some money buying a new phone for my wife and tossing this one which is the best for its small size imho.
Thank you in advance to anyone interested in at least shading some light on what could have happened. This started to happen out of the blue and the last time I actively modified something (updating the recovery) was almost one year ago... It always worked like a charm until 4 days ago...
EDIT: To clarify: the reason why I posted here is because this looked like a problem the most similar to mine (boot loop or stuck at boot and can't enter either regular or recovery mode). I cannot create new posts due to my low "rank" yet... Please feel free to move this if you think it belongs to a separate thread.

3. Flashed two different versions of stock ROM (the original one and the one that T-Mobile released when upgraded to latest jelly Bean)
4. Flashed a custom ROM (Light ROM found here which is based on the stock one).
EVERY TIME the outcome was the same:
Phone reboots right after the phone name (written in white) while the Samsung animation starts. It just stops while the blue oval begins to appear. If I try to boot into recovery (via home/power/volume up combo) it shows the TWRP splash screen but it reboots right after and this happened even after I flashed (successfully according to Odin) CWM.
It really looks like I did nothing so far but I can assure it's not the first time I use Odin (4 different versions) to flash a custom recovery or a ROM. I did it successfully on other 4 different phones (all samsung).
On this same phone I did it the first time when flashed TWRP in order to root it via recovery.
I have no idea what to do next. I was thinking about using adb in order to wipe all the caches (dalvik included) but it looks like the phone can't be recognized unless I boot it into recovery mode (adb get-state returns "unknown") and I don't think I can do anything in Download mode which is the only mode I can enter apparently.
I was hoping someone here can help me to spare some money buying a new phone for my wife and tossing this one which is the best for its small size imho.
Thank you in advance to anyone interested in at least shading some light on what could have happened. This started to happen out of the blue and the last time I actively modified something (updating the recovery) was almost one year ago... It always worked like a charm until 4 days ago...
EDIT: To clarify: the reason why I posted here is because this looked like a problem the most similar to mine (boot loop or stuck at boot and can't enter either regular or recovery mode). I cannot create new posts due to my low "rank" yet... Please feel free to move this if you think it belongs to a separate thread.

ok so i read all that you have done which is basically everything i would of suggested to you other then could it be the battery may be faulty just random thought noticed you never mentioned trying kies you may have a chance with it beening detected as i see you can enter download mode so that help with odin also kies also have you tried firmware from here sam mobile here T399 or T399N OH2 lastest for tmo and OH3 for metro.
Try to only flash that thru odin i use 3.07 or 3.09 only difference is the pda button changes to AP .works perfect for me so i suggest it then returning back to stock recovery/firmware if it boots then awesome. then return to TWRP 2.8.4.0 beening lastest for this device also needed for CM12 also my projects for device current and future.
when using odin make sure that only “Auto Reboot” and “F. Reset Time” options are selected.
also just note when going into twrp release buttons as soon as you see logo otherwise it will continue to boot thru well happens to me when daydreaming lol.
also if your seeing this adb get-state returns "unknown" i believe installing kies may install the drivers for detection im not postive on that but im sure it something to do with missing the adb driver for device maybe another dev can confirm this ?
hopefully this may be of some help i keep on thread to see how the outcome goes
Thanks for the reply DJBoxer!
Regarding the battery it's a new one and I can confirm it's not a battery problem considering that the phone can stay in download mode and unplugged from any power source for very long times without turning off/rebooting and it never failed to keep the charge so far. I also tried with the old battery and the phone behaves exactly the same way.
I used 3 different versions of Odin (1.87, 3.07 and 3.09) with only “Auto Reboot” and “F. Reset Time” options selected and every time I got the PASS message even though the phone keeps rebooting after the first reboot once the procedure is terminated.
To clarify one thing : when I said "it shows the TWRP splash screen but it reboots right after and this happened even after I flashed CWM" I meant to point out that it looks odd to see the TWRP splash screen (even for just a few seconds) after I just flashed CWM and that makes me think that I'm really not flashing anything here...
Thank you very much for taking the time of posting the links and I actually didn't try with that latest OH2 version.
I am downloading it right now (it takes a while from sammobile) and I will keep you posted on the outcome.
I will try to flash it via Odin and I'll also try the latest version mentioned on sammobile (Odin3_v3.10.7).
Regarding Kies I wasn't able to have it recognize the phone. I may be missing something but I tried updating drivers and going through all the guided procedures with no luck... If you say it should recognize the phone right away while in download mode then something is amiss.
Could you please confirm that I should also be able to use adb commands with the phone connected via USB in download mode? Cause that doesn't look like the case either...
Thank you again and I'll give updates here about my last attempts.
Sorry for the late reply...
Nothing changed by the way...
I am about to send the phone back to the seller who told me they'll try to fix it. Let's see how it goes.

My Galaxy S6 stuck in boot loop after root

Hello, so I have a Galaxy S6 on Android 6.0.1 and I'm with T-mobile. I tried to root the phone using Odin first, downloaded a root checker and got the confirmation. And then I tried to get Xposed using TWRP but I had to back up my phone and all that first. After being prompted to reboot I chose an Xposed zip and since then I haven't been able to get past the Samsung logo during reboot. I've tried all the button combinations and I can get as far as the Warning screen about downloading custom OS asking to press volume up to continue or down to cancel and restart. Both of them take me to the Samsung logo where I get stuck with it flickering at me. At this point I'm panicking and waiting for the battery to drain on the blue Warning screen. Right now I have it plugged into the computer on the battery charging screen. I'm scared to turn it on and see I'm still stuck in the loop. Please help me, I cannot afford another smart phone and I had to buy this one unlocked full price. Thanks.
Edit: After turning on my phone and seeing the boot loop was still very real, I went into download mode and tried to factory reset the phone. This actually took me to the Team Win Recover Project 3.0.2-1 where is has the standard buttons for install, backup, restore, reboot, etc. At this point I am not sure what to do, I believe this is where I would want to install the Xposed zip but I am not going to proceed until I have a clear understanding on what it is I need to do.
Edit 2: I should also mention that on the TWRP recovery screen, the restore tab is EMPTY. I guess I either did not completely save a nandroid state, or didn't name it something I could find. I'm unsure on how to restore the phone to factory settings, if at all possible, with TWRP.
Edit 3: After doing some research, I've decided that my best bet is probably to download the necessary firmware for my phone, Model number SM-G920F, and use Odin once again or Smart Switch to hopefully revert back to factory settings. The problem I am now having is finding the right firmware. I'm on SamMobile but I cannot find a firmware that fits my country and carrier. I know that unstalling the wrong firmware can brick my phone so I am being very hesitant here. Can anyone help me?
I'm a bit confused...did you already install a version of Xposed that caused the bootloop or it just started bootlooping after the first reboot after it booted from the rooting process?

I only installed Xposed once, and that is when the boot loop started. I had to reboot my device two times; once for Odin, and once for TWRP to get Xposed. Like I said, I went with Odin first for the rooting process and then I used TWRP in an attempt to get the third party firmware. After rebooting for Odin I ran the root checker and everything was confirmed. If it isn't obvious by now, I'm new to this whole process and goofed somewhere along the line so there's my disclaimer. At this point I'm willing to do anything to get this phone working again. I appreciate any help.
Just run the Xposed uninstaller in TWRP.
I have seen this with my wife's galaxy s6 edge, she had dropped the phone after having it for three weeks and then the phone started to act funny. Luckily for me I did not root the phone yet so I did the button combination but instead of volume down I did volume up so I can do a complete factory reset. That had seemed to help, you can always go back to the Samsung site to get the rom you need for your phone and if its with T-Mobile which I also have, you should have no problem getting it.

I have tried the button combination that is supposed to lead to the factory reset, but this is what is taking me to the TWRP screen. What I haven't tried is finding the ROM from the site so I will try that now, thanks!

You don't need to flash the whole rom. Just run the Xposed uninstaller. It was specifically made to resolve these types of issues.

In the TWRP screen I'm not seeing anything about unistalling Xposed, do you know what tab it would be under?
You have to grab the zip from the Xposed thread. You should be able to connect your phone in recovery to the PC and drag and drop it. If not, you might need to use ADB.
Don't flash a firmware unless you are 100% sure it's the official firmware for your device. Maybe you could contact the company's website and ask for the firmware. Sometimes this works. If it doesn't search for one but be sure to flash the official one or it may cause problems.

You will never guess how this man put his phone in a bootloop!!!

First hello people who'll come here.
So here is the issue. I tried to root my Honor 7 and everythings did well to the moment when i want to leave recovery mode by a reboot. At this moment i was blocked in TWRP. I searched how to leave it and i found this http://forum.xda-developers.com/showthread.php?t=1845768 but i don't know if it works cause when i managed to leave recovery mode and go in bootloader i totally forget this. I was in bootloader and my first reaction was to change the version of TWRP beacause mine was in chinese so a little bit more complicated. But whith this process i put the phone in a bootloop. So i asked to you if someone could help me first to leave this bootloop without wait for the battery (all passed yesterday but actually the phone do not have enought battery so i managed to go in bootloader mode) and help to leave TWRP if i do again the manipulation.
Thanks in advance.
I followed this http://forum.xda-developers.com/honor-7/general/how-to-root-honor-7-t3170735

so,to leave the bootloop,you need a stock ROM/custom ROM for your device and flash it,it should recovered from bootloop,
and if you try to root it again,i suggest you to use another guide of how to root it and by following your phone model..
Instructions:
1.Download the Stock ROM/Custom ROM for your phone model,make sure the rom is the same model for your device or else,you're gonna be in a bootloop again,all phone model are practically not the same! remember this if you attempting to modified your device
2.after the rom has been downloaded,put the rom in any sd card,and then insert sd card that have the rom in it.
3.in this case,you need to format the system,data,cache, formatting the data is optional though,but if it still bootlooping,consider yourself to format the data,if you want the data to not be erase,dont format it or if you want a clean install,backup the Data
3.Flash the rom using the TWRP recovery that you have installed
4.Reboot to the system
And the problem are gonna fixed
